Artificial intelligence technologies are being increasingly relied upon in the healthcare domain, particularly when it comes to decision support, precision medicine, and levitra cheap online the improvement of the quality of care. Regarding primary care specifically, AI also represents an opportunity levitra cheap online to assist with electronic health record documentation. A new study published in the Journal of American Medical Informatics Association this week shows that, although AI documentation assistants (or digital scribes) offer great potential in the primary care setting, they will need to be supervised by a human until strong evidence is available for their autonomous potential. In workshops with primary care doctors, wrote researchers from the Australian Institute of Health Innovation, "There was consensus that consultations of the future would increasingly involve more automated and AI-supported systems levitra cheap online. However, there were differing views on how this human-AI collaboration would work, what roles doctors and AI would take, and what tasks could be delegated to AI."

Get Started levitra cheap online >>. WHY IT MATTERS Researchers worked with primary care doctors who use EHRs regularly for documentation purposes to understand their views on future AI documentation assistants. They identified three major themes that emerged levitra cheap online from the discussions. Professional autonomy, human-AI collaboration and new models of care. First, levitra cheap online the doctors emphasized the importance of their ability to care for patients in their own way with the abilities AI technology provided."If they [patients] think that we're just getting suggestions from a computer, then maybe they can just get suggestions from a computer.

I think it becomes more difficult to convince them that our recommendations are more valuable than what they can pick up on the internet," said one physician. They noted the need for a bottom-up approach to technology development, with a focus on delivering levitra cheap online clear benefits to practice and workflow, and expressed fears around potential legal complications that could stem from working with an AI assistant.With regard to human-AI collaboration, doctors expressed a variety of viewpoints about what tasks could be delegated to AI. Many believed that an AI system could assist with tasks such as documentation, referrals and other paperwork. Most said that AI systems would lack levitra cheap online empathy. "GPs voiced several concerns, including some potential biases in patient data and system design, the time needed to fix the errors and train the system, challenges of dealing with complex cases, and the auditing of AI," wrote the researchers.

However, levitra cheap online doctors also discussed how AI could help with emerging models of primary care, including preconsultation, mobile health and telehealth. THE LARGER TREND The question of reducing EHR-related clinician burnout has loomed large, with vendors and researchers trying to pinpoint major causes – and, in turn, potential solutions. AI has been raised as one such solution, with several major levitra cheap online EHR vendors offering plans for incorporating the technology into their workflows. But human input remains vital, as the new JAMIA study and other research has noted. AI could "bring back meaning and purpose in the practice of medicine while providing new levels levitra cheap online of efficiency and accuracy," wrote Stanford researchers in a 2017 Journal of the American Medical Association study.

But, they continued, physicians must "proactively guide, oversee, and monitor the adoption of artificial intelligence as a partner in patient care."ON THE RECORD"AI documentation assistants will likely ... Be integral to the future primary care levitra cheap online consultations. However, these technologies will still need to be supervised by a human until strong evidence for reliable autonomous performance is available. Therefore, different human-AI collaboration models will need to be designed levitra cheap online and evaluated to ensure patient safety, quality of care, doctor safety, and doctor autonomy," wrote the Australian Institute for Health Innovation researchers.

@kjercichHealthcare IT News is a HIMSS Media publication.Konica Minolta Healthcare Americas will pay $500,000 to settle a whistleblower case that alleged its Viztek electronic health record subsidiary had falsified levitra cheap online data for certification tests.WHY IT MATTERSIn the qui tam complaint, filed in 2017 in U.S. District Court in New Jersey – where Konica Minolta is based – was filed by whistleblower Leighsa Wilson, who worked for two years at Viztek, best known for its PACS and imaging technologies, as a project manager for its EXA EHR product.In mid-2015, the complaint alleges, Viztek, which was in negotiations to be acquired by Konica Minolta, worked together with InfoGard Laboratories (which was then an ONC-authorized certification and testing body) to make false representations that the EHR software complied with requirements for certification – and qualified for receipt of incentive payments under the federal meaningful use program."To ensure that their product was certified and that their customers received incentive payments, Viztek and Konica Minolta. (a) falsely attested to InfoGard that their software met levitra cheap online the certification criteria. (b) hard-coded their software to pass certification testing requirements temporarily without ensuring that the software released to customers met certification criteria. And (c) caused their users to falsely attest to using a certified EHR technology, when their software levitra cheap online could not support the applicable certification criteria in the field," according to the complaint, which also alleges that InfoGard "facilitated and participated in" these false attestations, "knowingly or with reckless disregard," certifying the EHR software despite its inability to meet ONC's certification criteria.The flaws in Viztek's software "not only rendered the system unreliable and unable to meet meaningful use standards, but the flaws also created a risk to patient health and safety.

Rather than spend the time and resources necessary to correct the flaws in its EHR software, the EHR defendants opted to do nothing."THE LARGER TRENDThis is only the most recent settlement of this type from health IT vendors accused of False Claims Act violations, of course.Most notable, was the case of eClinicalWorks, which was alleged by the Department of Justice to have falsely claimed meaningful use certification, to have neglected to have safety addressed issues in its software and to have paid kickbacks to clients. That case was settled in 2017 for $155 million.More recently, similar complaints were lodged against companies such as Practice levitra cheap online Fusion and Greenway Health. They settled with DOJ for $145 million and $57 million, respectively."We will be unflagging in our efforts to preserve the accuracy and reliability of Americans’ health records and guard the public against corporate greed," said U.S. Attorney for the District of Vermont Christina Nolan after the Greenway case this past levitra cheap online year. "EHR companies should consider themselves on notice."ON THE RECORD"The lives of patients depend upon the information processed by electronic health records," said Wilson – who, as a qui tam whistleblower will receive 20% of the financial settlement – in a statement.

"Functionality testing and subsequent certification must be performed and obtained through a reliable, measurable process.""Filing a qui tam lawsuit is a powerful and effective way to report levitra cheap online problems with EHR software purchased with federal funds and get the problems fixed when they are ignored," said Luke Diamond, an associate at Phillips &. Cohen. "The False Claims Act protects whistleblowers from job retaliation and offers rewards if the government recovers funds as a result of the levitra cheap online qui tam case.""Our client was concerned about possible patient harm that can occur if EHR software isn't properly certified, so she stepped forward to inform the government about what she had witnessed," said Colette Matzzie, a partner and whistleblower attorney with Phillips &. Cohen, which brought the case. "Ensuring that EHR software meets all governmental requirements is important to safeguard both patient care and federal funds."The Arc Madison Cortland in Oneida, New York, knows that levitra cheap online there is a lack of providers that specialize in the intellectual/developmental disability field.

Making the problem worse, levitra cheap online not so many that understand dual diagnosis.THE PROBLEMWith COVID-19 minimizing the ability for individuals to receive face-to-face services with their providers, many patients are resorting to emergency department visits.Additionally, The Arc is in a rural area requiring travel to see a provider, and there is a lack of providers in the field. The population itself is underserved, with a lack of transportation to get to appointments. Without the ability to institute telemedicine as a levitra cheap online solution to these problems, the population supported by The Arc would have seen a lengthy (permanent?. ) pause for needed medical services.PROPOSALThe Arc this year received funding from the FCC to help provide telehealth services.“With this funding we can further treat patients, reduce crisis and allow for social distancing, which is imperative to our vulnerable population,” said Jackie Fahey, director of clinic services at The Arc Madison Cortland. €œWe could provide ongoing services to the individuals levitra cheap online we serve to ensure there are no unnecessary emergency department visits.

This places less of a strain on our local emergency departments and unneeded additional costs.”With the purchase of tablets and headsets and telehealth services from vendor Doxy.me, The Arc was able to still provide medical care to its population of people with an I/DD. Additionally, eliminating emergency department visits also eliminates their exposure to COVID-19 and eases the burden of the ED providers who are overburdened right now.MARKETPLACEThere are many vendors of telemedicine technology and services on the health IT market levitra cheap online today. Healthcare IT News recently compiled a comprehensive list of these vendors with detailed descriptions. To read this special report, click here.MEETING THE CHALLENGE“When all of our locations were closed abruptly in the middle of March due to the COVID-19 pandemic, we needed to determine a way to quickly and easily implement a telehealth levitra cheap online solution so that we were able to still support the individuals that we serve during the crisis, especially when many were under strict quarantine protocols for a variety of reasons,” Fahey explained.“We signed up immediately for the Doxy.me telehealth platform as it was a user-friendly platform that is HIPAA-compliant. The feature we liked about Doxy.me was that it is web-based, so nothing had to be downloaded and it could easily be used on a laptop, tablet or smartphone.”The Arc rolled out the technology initially with its mental health providers, who offer psychiatry/medication monitoring services, social work counseling and mental health counseling.

More than half the organization’s enrollment is enrolled in one or all of these three services, so it was able to continue providing services to a large number of enrolled individuals.“We then began to roll the telehealth services out to nutrition, speech therapy, physical therapy and occupational therapy caseloads if individuals were appropriate to receive the service through telehealth,” Fahey said.RESULTSThe first success metric The Arc has been able to achieve with the technology is maintaining levitra cheap online its utilization for mental health services. When everything was running normal prior to COVID-19, The Arc’s mental health services made up about 25% of the services it provided on a monthly basis. With the implementation of telehealth services during the COVID-19 pandemic, the organization was able to achieve 20% of the services provided on a monthly basis.This has shown to staff that they have been able to still serve and respond to the needs of their psychiatry, social work and mental health counseling patients with minimal issues by implementing the telehealth technology.“The second success metric we have been able to achieve with the technology is levitra cheap online we have been able to continue to receive referrals for our services and enroll new individuals into the services they need if the services are able to be completed via telehealth,” she said. €œBetween April, May and June, we have enrolled 16 new individuals into ongoing clinic services, which is right on par for our normal enrollment average per month.”USING FCC AWARD FUNDSThe Arc Madison Cortland was awarded $49,455 by the FCC earlier this year for laptop computers and headsets to provide remote consultations and treatment during the COVID-19 pandemic for psychological services, counseling, and occupational and physical therapy for people with developmental and other disabilities.“With the funds, we purchased headsets and tablets to allow the people we support to have access to medical appointments, along with physical therapy, occupational therapy and psychology appointments remotely,” Fahey explained. €œThe technology enables us to continue to provide these services at levitra cheap online a time when the people we support are unable to leave for traditional in-person appointments.“Because these are such uncertain times, and a time frame for when we may return to ‘normalcy’ is unknown, the technology allows us to continue delivering medical support without the concern of a pause in those services.”Twitter.

@SiwickiHealthITEmail the writer. Bill.siwicki@himss.orgHealthcare IT News is a HIMSS Media publication.HIMSSCast host Jonah Comstock convenes a panel of HIMSS Media editors – HITN Senior Editor Kat Jercich, MobiHealthNews Associate Editor Dave Muoio and HFN Associate Editor Jeff Lagasse – to discuss recent delivery slowdowns at the Post Office and how they have and haven't affected healthcare levitra cheap online stakeholders, including startups and patients. The team also looks into the broader trend of the politicization of traditionally apolitical government agencies and how that could affect public faith in COVID-19 treatments or vaccines.More about this episode:USPS service delays are hitting some mail-order pharmacies and telehealth platforms harder than othersMail delays may affect medication supply for nearly 1 in 4 Americans over 50Postmaster General Louis DeJoy's full testimony (C-SPAN)The Package Coalition homepageThe Trump administration this week asked the U.S. Supreme Court levitra cheap online to reverse a lower court ruling that allowed for mail-order and telemedicine abortion during the COVID-19 crisis. U.S.

Food and Drug Administration regulations require mifepristone, which is used in medication abortion, to levitra cheap online be dispensed at a clinic, hospital or medical office. In June, U.S. District Judge for the District of Maryland Theodore Chuang levitra cheap online blocked the requirements during the pandemic, finding them to be a "substantial obstacle." Mifepristone, in combination with misoprostol, is FDA-approved for abortions up to ten weeks' gestation. In 2017, a New England Journal of Medicine article argued against the FDA regulations for mifepristone given the drug's safety record. WHY IT MATTERS Acting Solicitor levitra cheap online General Jeffrey B.

Wall applied for a stay of Chuang's injunction on Wednesday as the case makes its way through the lower courts, arguing that the regulations do not represent an undue burden. "The safety requirements here concern only medication abortions using Mifeprex, which is approved for use only levitra cheap online during the first ten weeks of pregnancy. They have no effect on the availability of surgical abortions, a method that this Court has treated as safe for women," wrote Wall. Reproductive rights groups spoke out against the move, noting that people of levitra cheap online color are disproportionately affected both by abortion restrictions and by the COVID-19 pandemic. "Black, Brown, Indigenous people and people of color are already dying/getting sick at disproportionate rates from COVID-19," said All Above All* on Twitter.

"The Trump-Pence admin is trying to make this worse by asking SCOTUS to require people face unnecessary risk just to get abortion care." "The FDA’s in-person requirements on mifepristone subject patients to unnecessary exposure to a levitra cheap online deadly virus, and two federal courts have already rejected the Trump administration’s argument. Forcing patients to travel to a health center to access the safe, effective medication they need especially hurts people of color and people with low-incomes, who already face more barriers to care," said Planned Parenthood Federation of America President and CEO Alexis McGill-Johnson in a statement.THE LARGER TREND The COVID-19 pandemic has exacerbated many existing barriers to care, including for reproductive health services. "We’ve seen the undue burden and hardship these restrictions create during COVID-19, especially in communities hit hardest by the pandemic," said Skye Perryman, chief legal officer at the American College of Obstetricians and Gynecologists, a co-plaintiff in the telemedicine case, to Healthcare IT levitra cheap online News. In response to the July ruling, some abortion providers reportedly moved to delivering mifepristone by mail. Still, others faced state laws levitra cheap online that restricted the provision of abortion via telemedicine.And as Dr.

Jacquelyn Yeh from Physicians from Reproductive Health pointed out in July, telemedicine itself involves hurdles such as broadband access and privacy concerns. It remains to be seen whether the Supreme Court will grant the levitra cheap online Trump administration's request. ON THE RECORD "As COVID-19 ravages Black, Latino, Indigenous, and other communities of color across the country, the Trump administration should be aiming to keep us healthy – not moving forward with an agenda to endanger people who seek abortion," said McGill-Johnson.

Is i magenThe Swedish expression http://sw.keimfarben.de/how-much-does-generic-levitra-cost/ ‘att ha lite is i buy levitra uk online magen’ (literally to have some ice in the stomach) like many idiomatic aphorisms, is hard to translate directly. The advantage, of course, is the flexibility that being unbound to a set definition affords and it has come to mean both ‘have something in reserve’ and to ‘keep cool’.Whichever definition is used (and they aren’t mutually exclusive) each of the featured papers imbues us with extra ‘is’, affirms we’re on roughly the right track or that our suspicions of a wrong turn have been corroborated.Preventable child mortality. European figuresUsing WHO global database coding and an incidence rate ratio approach, Ward examines UK standing relative to 17 buy levitra uk online other European countries in preventable child and adolescent mortality.

The numbers (both in progress and current grade in the class) make for uncomfortable reading. UK mortality in 2015 was significantly higher than buy levitra uk online the EU15 +for common infections. Chronic respiratory conditions and digestive, neurological and diabetes/urological/blood/endocrine conditions in teenaged girls.

The UK had the worst to third worst mortality buy levitra uk online rank for common infections in both sexes and all age groups, and in five out of eight non-communicable disease (NCD). Worryingly, despite relatively better placings on injury-related deaths, total mortality has increased year on year since 2013 among adolescent girls and in an estimated two thirds of UK deaths due to asthma and a quarter of deaths in children with epilepsy there were avoidable factors. See page buy levitra uk online 1055So, where next?.

Availability of paediatric expertise early in the illness course (debate point—is this a collateral (positive) effect of COVID-19?. ) to improve recognition of severity has promise but cannot alone compensate for the disparities with which the UK has wrestled for so long.Adolescent healthFemale genital mutilationAli’s examination of referral buy levitra uk online and outcome data in girls seen at London FGM specialist clinic over 5 years (2014–2019) find that the number and proportions to be substantially lower than expected based on UK prevalence estimates. Median age at assessment was 13 years, most children had undergone FGM prior to UK entry and in most cases were initially disclosed by the child or family themselves.

With the usual provisos of case ascertainment, these results suggest that, though there are still buy levitra uk online pockets of practice, it is largely being abandoned by communities after migration. See page 1075Racism. Psychological effectsIn the speak out against racism (SOAR) study, Priest evaluates buy levitra uk online associations between self-reported direct and vicarious racism on psychological well-being in Australian adolescents.

Outcomes were quantified by the Strengths and Difficulties Questionnaire and sleep duration and sadly but unsurprisingly, direct and vicarious experiences of racial discrimination were associated with difficulty in socioemotional adjustment and poorer sleep duration. See page 1079Protracted bacterial bronchitisThough the term protracted bacterial bronchitis (PBB) has existed for years, the label had a spell in the wilderness not so long ago, the result of scepticism as to whether the diagnosis (requiring a persistent wet cough and response to antibiotic treatment) was, in fact, a buy levitra uk online separate entity. I suspect that the use of the term ‘bronchitis’ was thought by many to be too nebulous, but, with the wider use of broncho-alveolar lavage and hard evidence of intrabronchial inflammation, the phenotype is now firmly accepted.

There is a recognised association with relapse and later bronchiectasis and although standard treatment consists of a ‘long course’ of antibiotics, the best of which has been amoxycillin-clavulanate, the problem is no-one knows what duration that should mean. Gross-Hodge’s evaluation of the buy levitra uk online North Midlands University Hospitals’ database strongly suggests that a 6 rather than 2 week course should be chosen with an OR (95% CI) for recurrence of 0.12 (0.03 to 0.51). Biologically, this seems plausible, longer duration courses possible can break down bronchial bacterial biofilms more successfully.

These data are observational, but any allocation bias would be likely to be in favour of the 2 week course based on the sicker-appearing children being given longer courses and an RCT now feels buy levitra uk online overdue. See page 1111E cigarettes. HypersensitivityAfter a buy levitra uk online Warholian 15 min of fame, basking in their ‘healthy (or less harmful) alternative’ label, reality (and infamy) is catching up with low tar cigarettes.

Literature in this area is accumulating, but, little as directly implicating as Bhatt’s report showing clinical, immunological and histological evidence of a pulmonary hypersensitivity reaction in a ‘casual vaper’, triggers likely being propylene glycol, vegetable glycerides or the flavourings inherent to the experience. See page 1114TraditionsIn a delightful Voices from buy levitra uk online History, Emma Sharland chronicles the origins of oral penicillin V dosing. This appears to have become established in children after use by a GP in 1955 based on a child receiving half an adult’s dose and an infant half of that which a child receives.

The scientific buy levitra uk online basis for this and subsequent BNF recommended dosing?. Almost none, but the tradition was set and, despite pharmacokinetic and body composition science has never been seriously challenged. See page 1118EnvironmentAfter some lockdown-related delays, Archives is now buy levitra uk online being mailed in a polymer derived from the waste products of sugar cane processing, polyair.

This is still a single-use plastic wrapping, but it is made up of 75% biological material, is recyclable in plastic recycling collections, and has been certified as carbon neutral by the Carbon Trust. Progress on recyclable paper buy levitra uk online wrapping has been slow because of COVID-19 and lockdown but is still very much the aim. Armed with this ‘is’, you should be feeling ‘varmare i kläderna’—but that’s a tangent for another day…IntroductionIn the midst of lockdown, just as patient acuity and bed pressures eased, a number of teenagers were transferred to the paediatric intensive care unit (PICU) at Evelina London Children’s Hospital for inotropic support in the absence of respiratory involvement or any features of acute Severe acute respiratory syndrome related coronavirus 2 (SARS CoV-2) infection.1 All patients had features of toxic shock syndrome (TSS) but no pathogens were identified despite extensive microbiological investigation.

Several new patients presented buy levitra uk online over the next few days. Febrile with high inflammatory markers and multisystem involvement. The unusually high number of cases raised concerns, which were discussed with Public Health England regarding a possible infectious disease cluster with pathogen unknown.Following several discussions with National Health Service England (NHSE) and pan-London tertiary paediatric services who had also seen cases, a consensus was reached that a new http://sw.keimfarben.de/low-cost-levitra/ clinical phenomenon was being seen across London.

It was sufficiently concerning to send out an NHSE alert at the end of April which triggered international discussion.2 Numerous teleconferences later, the emerging condition had a name buy levitra uk online. Paediatric inflammatory multisystem syndrome temporally associated with SARS-CoV-2 (PIMS-TS).3 Since the alert other countries have reported similar cases (figure 1).4 ,5 ,6Timeline of paediatric inflammatory multisystem syndrome temporally associated with SARS-CoV-2 (PIMS-TS) development.1–4 6–9 NHSE, National Health Service England." data-icon-position data-hide-link-title="0">Figure 1 Timeline of paediatric inflammatory multisystem syndrome temporally associated with SARS-CoV-2 (PIMS-TS) development.1–4 6–9 NHSE, National Health Service England.PresentationOver 6 weeks more than 70 patients were admitted to Evelina London Children’s Hospital who fulfilled criteria for a diagnosis of PIMS-TS.3 The majority of patients were between 9 years and 16 years of age with the youngest presenting at only 3 months. A higher proportion of patients was male, from black, Asian and buy levitra uk online minority ethnic groups, and had a parent classed as a key worker.All of the patients presented with a history of fever and most presented with gastrointestinal symptoms including abdominal pain, diarrhoea or vomiting.

A number of patients were transferred following surgery for symptoms and signs classical of acute appendicitis but intraoperatively found to have a normal appendix. Other presenting features included conjunctivitis, rashes and lethargy.Key laboratory findings on presentation included a very high C reactive protein buy levitra uk online (CRP), high ferritin, raised neutrophils, low lymphocytes, raised D-dimer, raised troponin I, raised N-terminal pro B-type natriuretic peptide and low vitamin D levels.The most common cardiac manifestation was myocarditis with impaired function. Other cardiac abnormalities included arrhythmias, ischaemia and pericardial effusions.

Patients were monitored closely for coronary artery dilatation which in buy levitra uk online some patients continued to progress despite improvement in clinical symptoms and laboratory markers.Acute kidney injury was the most common renal complication which improved with conservative management. Some patients developed thrombus formation and pulmonary emboli due to their prothrombotic state. Neurological involvement was also observed with one patient developing autoimmune encephalitis.PathogenesisMost patients buy levitra uk online with PIMS-TS reported no preceding illness or mild symptoms consistent with COVID-19, 4–6 weeks prior to presentation.

Others had a household member with previous symptoms consistent with COVID-19 infection. Most patients with PIMS-TS were SARS-CoV-2 PCR-negative but positive for IgG antibodies against SARS-CoV-2 indicating buy levitra uk online previous infection. It has been postulated that a host immune response to SARS-CoV-2 triggers an inflammatory response.Although cases of PIMS-TS have similarities to Kawasaki disease (KD) and TSS, there are clear differences.7 Patients with PIMS-TS are older and present with higher inflammatory markers including CRP and ferritin plus higher troponin I suggestive of myocardial ischaemia.

Like TSS a proportion of patients with PIMS-TS present in shock with poor cardiac function but none buy levitra uk online had confirmed staphylococcus or streptococcus on microbiology.ManagementAssessment, stabilisation and early involvement of specialist centresThe majority of the patients needed intensive care for cardiovascular instability requiring single or multiple inotropic agents. Early discussion with specialist centres and transfer to a centre with PICU and cardiology on site is a necessity.Management for each patient was decided within a multidisciplinary team (MDT) setting including General Paediatrics, Cardiology, Paediatric Infectious Diseases and Immunology (PIID), Rheumatology, PICU, Haematology, Renal and Pharmacy, with re-evaluation on a twice daily basis as a minimum. A General Paediatric overview was vital in coordinating the MDT and providing holistic care.TreatmentIn our cohort, as we gained experience, prompting earlier diagnosis and treatment initiation, fewer cardiac complications and reduced buy levitra uk online PICU stay were observed.

Treatments included intravenous immunoglobulin, methylprednisolone and biologics including tocilizumab, infliximab and anakinra. Currently there is no evidence for this area and recruiting children to research studies such as Recovery (https://www.recoverytrial.net/) and the ‘Best available treatment study (BATS) for inflammatory conditions associated with COVID-19’ (https://doi.org/10.1186/ISRCTN69546370) will hopefully provide evidence on which to base our treatment decisions. All patients receiving treatment were routinely prescribed aspirin, prophylactic dalteparin, high dose cholecalciferol and omeprazole.Psychology and supportPlay therapy involvement and psychological support for this cohort was buy levitra uk online quickly escalated.

Families were understandably extremely worried by the sudden clinical deterioration of their previously well child and need for intensive care. Multiple interventions including scans, cannulas and blood tests by staff masked in buy levitra uk online personal protective equipment added to the stress. Psychology support is now a routine part of the care offered.Overcoming challengesTo cope with the large number of unpredictable and high acuity patients with PIMS-TS, additional staffing was required on our paediatric wards.

Within days, the number of high dependency unit (HDU) beds buy levitra uk online was rapidly increased to accommodate the intense level of monitoring and treatment required. Ward rounds, handovers, MDT meetings and pathways were rapidly revised and implemented. We sought the return of our buy levitra uk online experienced paediatric nurses and doctors who had been redeployed to adult services.

Additional pharmacists, psychologists and play therapists also joined a newly created and dedicated PIMS-TS team with representation from General Paediatrics, PIID, Cardiology and Rheumatology to manage the daily care of the patients. This ensured individualised, holistic management plans could be made to buy levitra uk online provide the highest quality of care. The responsiveness by everyone involved was phenomenal.As patients are discharged the next challenge is ensuring follow-up plans are appropriately tailored, responsive and clinically robust.

In the current lockdown era, this buy levitra uk online is no small task given the numbers involved, the follow-up investigations needed, plus national pressures to reduce face-to-face appointments.Managing a new condition with no published consensus on treatment was a huge challenge, especially given the large numbers and high acuity of the patients who were admitted. Seeking out opinions, information and advice from other centres, nationally and internationally, as well as shared learning with other paediatric specialities has been key in helping manage these children. Collaborative learning and reflection has enabled buy levitra uk online us to develop a treatment pathway and shared management pathway for our patients.

We have witnessed the MDT working at its best within the hospital, united with the sole aim of combating this rare condition.Next stepsLong-term follow-up is essential to enable us to understand the long-term implications and prognosis for these patients. Planning and vigilance is required to manage a possible influx buy levitra uk online of patients with PIMS-TS if there is another surge of SARS-CoV-2.An ongoing coordinated effort is required to undertake paediatric research to understand PIMS-TS and establish the most effective treatment. The British Paediatric Surveillance Unit team is collecting data about all reported cases in the UK and Ireland.8 We eagerly await the publication of evidence which may support, or disprove an association with SARS-CoV-2.

Certainly, the clinical histories taken from this cohort offer fascinating glimpses into the possibilities of an association..

These data are observational, but any allocation bias would be likely to be in favour of the 2 week course levitra cheap online based on the sicker-appearing children being given longer courses and an RCT now feels overdue.

HypersensitivityAfter a Warholian 15 min of fame, basking in their levitra cheap online ‘healthy (or less harmful) alternative’ label, reality (and infamy) is catching up with low tar cigarettes.

Literature in this area is accumulating, but, little as directly implicating as Bhatt’s report showing clinical, immunological and histological evidence of a pulmonary hypersensitivity reaction in a ‘casual vaper’, triggers likely being propylene glycol, vegetable glycerides or the flavourings inherent to the experience.

This appears to have become established in children after use by a GP in 1955 based on a child receiving half an adult’s dose and an infant half of that which a child receives. The scientific basis for this and subsequent BNF levitra cheap online recommended dosing?.

Almost none, but the tradition was set and, despite pharmacokinetic and body composition science has never been seriously challenged.

This is still a single-use plastic wrapping, but it is made up of 75% biological material, is recyclable in plastic recycling collections, and has been certified as carbon neutral by the Carbon Trust. Progress on recyclable paper wrapping has been slow because of COVID-19 and lockdown but is still levitra cheap online very much the aim.

Armed with this ‘is’, you should be feeling ‘varmare i kläderna’—but that’s a tangent for another day…IntroductionIn the midst of lockdown, just as patient acuity and bed pressures eased, a number of teenagers were transferred to the paediatric intensive care unit (PICU) at Evelina London Children’s Hospital for inotropic support in the absence of respiratory involvement or any features of acute Severe acute respiratory syndrome related coronavirus 2 (SARS CoV-2) infection.1 All patients had features of toxic shock syndrome (TSS) but no pathogens were identified despite extensive microbiological investigation. Several new levitra cheap online patients presented over the next few days. Febrile with high inflammatory markers and multisystem involvement. The unusually high number of cases raised concerns, which were discussed with Public Health England regarding a possible infectious disease cluster with pathogen unknown.Following several discussions with National Health Service England (NHSE) and pan-London tertiary paediatric services who had also seen cases, a consensus was reached that a new clinical phenomenon was being seen across London.

It was sufficiently concerning to send out an NHSE alert at the end of April which triggered international discussion.2 Numerous teleconferences levitra cheap online later, the emerging condition had a name. Paediatric inflammatory multisystem syndrome temporally associated with SARS-CoV-2 (PIMS-TS).3 Since the alert other countries have reported similar cases (figure 1).4 ,5 ,6Timeline of paediatric inflammatory multisystem syndrome temporally associated with SARS-CoV-2 (PIMS-TS) development.1–4 6–9 NHSE, National Health Service England." data-icon-position data-hide-link-title="0">Figure 1 Timeline of paediatric inflammatory multisystem syndrome temporally associated with SARS-CoV-2 (PIMS-TS) development.1–4 6–9 NHSE, National Health Service England.PresentationOver 6 weeks more than 70 patients were admitted to Evelina London Children’s Hospital who fulfilled criteria for a diagnosis of PIMS-TS.3 The majority of patients were between 9 years and 16 years of age with the youngest presenting at only 3 months. A higher proportion of patients was male, from black, Asian and minority ethnic groups, and had a parent levitra cheap online classed as a key worker.All of the patients presented with a history of fever and most presented with gastrointestinal symptoms including abdominal pain, diarrhoea or vomiting. A number of patients were transferred following surgery for symptoms and signs classical of acute appendicitis but intraoperatively found to have a normal appendix.

Other presenting features included conjunctivitis, rashes and lethargy.Key laboratory findings on presentation included a very high C reactive protein (CRP), high ferritin, raised neutrophils, low lymphocytes, raised D-dimer, levitra cheap online raised troponin I, raised N-terminal pro B-type natriuretic peptide and low vitamin D levels.The most common cardiac manifestation was myocarditis with impaired function. Other cardiac abnormalities included arrhythmias, ischaemia and pericardial effusions. Patients were monitored closely for coronary artery dilatation which levitra cheap online in some patients continued to progress despite improvement in clinical symptoms and laboratory markers.Acute kidney injury was the most common renal complication which improved with conservative management. Some patients developed thrombus formation and pulmonary emboli due to their prothrombotic state.

Neurological involvement was also observed with one patient developing autoimmune encephalitis.PathogenesisMost patients with PIMS-TS reported no preceding illness or levitra cheap online mild symptoms consistent with COVID-19, 4–6 weeks prior to presentation. Others had a household member with previous symptoms consistent with COVID-19 infection. Most patients with PIMS-TS were SARS-CoV-2 PCR-negative but levitra cheap online positive for IgG antibodies against SARS-CoV-2 indicating previous infection. It has been postulated that a host immune response to SARS-CoV-2 triggers an inflammatory response.Although cases of PIMS-TS have similarities to Kawasaki disease (KD) and TSS, there are clear differences.7 Patients with PIMS-TS are older and present with higher inflammatory markers including CRP and ferritin plus higher troponin I suggestive of myocardial ischaemia.

Like TSS a proportion of patients with PIMS-TS present in shock with poor cardiac function but none had confirmed staphylococcus or streptococcus on microbiology.ManagementAssessment, stabilisation and early levitra cheap online involvement of specialist centresThe majority of the patients needed intensive care for cardiovascular instability requiring single or multiple inotropic agents. Early discussion with specialist centres and transfer to a centre with PICU and cardiology on site is a necessity.Management for each patient was decided within a multidisciplinary team (MDT) setting including General Paediatrics, Cardiology, Paediatric Infectious Diseases and Immunology (PIID), Rheumatology, PICU, Haematology, Renal and Pharmacy, with re-evaluation on a twice daily basis as a minimum. A General Paediatric overview was levitra cheap online vital in coordinating the MDT and providing holistic care.TreatmentIn our cohort, as we gained experience, prompting earlier diagnosis and treatment initiation, fewer cardiac complications and reduced PICU stay were observed. Treatments included intravenous immunoglobulin, methylprednisolone and biologics including tocilizumab, infliximab and anakinra.

Currently there is no evidence for this area and recruiting children to research studies such as Recovery (https://www.recoverytrial.net/) and the ‘Best available treatment study (BATS) for inflammatory conditions associated with COVID-19’ (https://doi.org/10.1186/ISRCTN69546370) will hopefully provide evidence on which to base our treatment decisions. All patients receiving treatment were routinely prescribed aspirin, prophylactic dalteparin, high dose cholecalciferol and omeprazole.Psychology and supportPlay therapy involvement and psychological support for this cohort was quickly levitra cheap online escalated. Families were understandably extremely worried by the sudden clinical deterioration of their previously well child and need for intensive care. Multiple interventions including scans, cannulas levitra cheap online and blood tests by staff masked in personal protective equipment added to the stress.

Psychology support is now a routine part of the care offered.Overcoming challengesTo cope with the large number of unpredictable and high acuity patients with PIMS-TS, additional staffing was required on our paediatric wards. Within days, the number of high dependency unit (HDU) beds was rapidly increased to accommodate levitra cheap online the intense level of monitoring and treatment required. Ward rounds, handovers, MDT meetings and pathways were rapidly revised and implemented. We sought the return of our experienced paediatric nurses and doctors who had been levitra cheap online redeployed to adult services.

Additional pharmacists, psychologists and play therapists also joined a newly created and dedicated PIMS-TS team with representation from General Paediatrics, PIID, Cardiology and Rheumatology to manage the daily care of the patients. This ensured individualised, holistic management levitra cheap online plans could be made to provide the highest quality of care. The responsiveness by everyone involved was phenomenal.As patients are discharged the next challenge is ensuring follow-up plans are appropriately tailored, responsive and clinically robust. In the current lockdown era, this is no small task given the numbers involved, the follow-up investigations needed, plus national pressures to reduce face-to-face appointments.Managing a new levitra cheap online condition with no published consensus on treatment was a huge challenge, especially given the large numbers and high acuity of the patients who were admitted.

Seeking out opinions, information and advice from other centres, nationally and internationally, as well as shared learning with other paediatric specialities has been key in helping manage these children. Collaborative learning and reflection has enabled us to develop a treatment pathway and shared management pathway for our levitra cheap online patients. We have witnessed the MDT working at its best within the hospital, united with the sole aim of combating this rare condition.Next stepsLong-term follow-up is essential to enable us to understand the long-term implications and prognosis for these patients. Planning and vigilance is required to manage a possible influx of patients with PIMS-TS if there is another surge of SARS-CoV-2.An ongoing coordinated effort is required to undertake paediatric research to levitra cheap online understand PIMS-TS and establish the most effective treatment.

The British Paediatric Surveillance Unit team is collecting data about all reported cases in the UK and Ireland.8 We eagerly await the publication of evidence which may support, or disprove an association with SARS-CoV-2. Certainly, the clinical histories taken from this cohort offer fascinating glimpses into the possibilities of an association..

That idea is at the heart of a fascinating new study of the differing effects of running and walking on the knee joint. Using motion capture and sophisticated computer modeling, the study confirms that running pummels knees more than walking does.

But in the process, the authors conclude, running likely also fortifies and bulks up the cartilage, the rubbery tissue that cushions levitra yorum the ends of bones. The findings raise the beguiling possibility that, instead of harming knees, running might fortify them and help to stave off knee arthritis.Of course, the notion that running wrecks knees is widespread and entrenched. Almost anyone who runs is familiar with warnings from well-meaning, nonrunning family members, friends and strangers that their knees are doomed.This concern is not unwarranted.

Running involves substantial levitra yorum joint bending and pounding, which can fray the cushioning cartilage inside the knee. Cartilage, which does not have its own blood supply, generally is thought to have little ability to repair itself when damaged or to change much at all after childhood. So, repeated running conceivably wears away fragile cartilage and almost inevitably should lead to crippling knee arthritis.But in real life, it does not.

Some runners levitra yorum develop knee arthritis, but not all. As a group, in fact, runners may be statistically less likely to become arthritic than nonrunners.The question of why running spares so many runners’ knees has long intrigued Ross Miller, an associate professor of kinesiology at the University of Maryland in College Park. In earlier research, he and his colleagues had looked into whether running mechanics matter, by asking volunteers to walk and run along a track outfitted with plates to measure the forces generated with each step.The resulting data showed that people hit the ground harder while running, clobbering their knees far more with each stride.

But they also spent more time aloft between strides, meaning they took fewer strides while covering the same distance levitra yorum as when walking. So, the cumulative forces moving through their knees over time should be about the same, the researchers concluded, whether someone walked or ran.But, recently, Dr. Miller had begun to doubt whether this finding really explained why running wasn’t wrecking more knees.

He knew that some recent studies with animals intimated levitra yorum that cartilage might be more resilient than researchers previously had believed. In those studies, animals that ran tended to have thicker, healthier knee cartilage than comparable tissues from sedentary animals, suggesting that the active animals’ cartilage had changed in response to their running.Perhaps, Dr. Miller speculated, cartilage in human runners’ knees likewise might alter and adapt.To find out, he again asked a group of healthy young men and women to walk and run along a track containing force plates, while he and his colleagues filmed them.

The researchers then computed the forces the volunteers had generated levitra yorum while strolling and running. Finally, they modeled what the future might hold for the volunteers’ knees.More specifically, they used the force-plate numbers, plus extensive additional data from past studies of biopsied cartilage pulled and pummeled in the lab until it fell apart and other sources to create computer simulations. They wanted to see what, theoretically, would happen to healthy knee cartilage if an adult walked for six kilometers (about 3.7 miles) every day for years, compared to if they walked for three kilometers and ran for another three kilometers each of those days.They also tested two additional theoretical situations.

For one, the researchers programmed in levitra yorum the possibility that people’s knee cartilage would slightly repair itself after repeated small damage from walking or running — but not otherwise change. And for the last scenario, they presumed that the cartilage would actively remodel itself and adapt to the demands of moving, growing thicker and stronger, much as muscle does when we exercise.The models’ final results were eye-opening. According to the simulations, daily walkers faced about a 36 percent chance of developing arthritis by the age of 55, if the model did not include the possibility of the knee cartilage adapting or repairing itself.

That risk dropped to about 13 percent if cartilage were assumed to be able to repair or adapt, which is about what studies predict to be levitra yorum the real-world arthritis risk for otherwise healthy people.The numbers for running were more worrisome. When the model assumed cartilage cannot change, the runners’ risk of eventual arthritis was a whopping 98 percent, declining only to 95 percent if the model factored in the possibility of cartilage repair. In effect, according to this scenario, the damage to cartilage from frequent running would overwhelm any ability of the tissue to fix itself.But if the model included the likelihood of the cartilage actively adapting — growing thicker and cushier — when people ran, the odds of runners developing arthritis fell to about 13 percent, the same as for healthy walkers.What these results suggest is that cartilage is malleable, Dr.

Ross says levitra yorum. It must be able to sense the strains and slight damage from running and rebuild itself, becoming stronger. In this scenario, running bolsters cartilage health.Modeled results like these are theoretical, though, and limited.

They do not explain how cartilage remodels itself without a blood supply or if genetics, nutrition, body weight, knee injuries and other factors affect levitra yorum individual arthritis risks. Such models also do not tell us if different distances, speeds or running forms would alter the outcomes. To learn more, we will need direct measures of molecular and other changes in living human cartilage after running, Dr.

Miller says, but such tests are difficult.Still, this study may quiet some runners’ qualms — and those of levitra yorum their families and friends. €œIt looks like running is unlikely to cause knee arthritis by wearing out cartilage,” Dr. Ross says.Weathered, wiry and in his early 60s, the man stumbled into clinic, trailing cigarette smoke and clutching his chest.

Over the previous week, he had had fleeting episodes of chest pressure but stayed away from the hospital.“I didn’t want to levitra yorum get the coronavirus,” he gasped as the nurses unbuttoned his shirt to get an EKG. Only when his pain had become relentless did he feel he had no choice but to come in.In pre-pandemic times, patients like him were routine at my Boston-area hospital. We saw them almost every day.

But for levitra yorum much of the spring and summer, the halls and parking lots were eerily empty. I wondered if people were staying home and getting sicker, and I imagined that in a few months’ time these patients, once they became too ill to manage on their own, might flood the emergency rooms, wards and I.C.U.s, in a non-Covid wave.But more than seven months into the pandemic, there are still no lines of patients in the halls. While my colleagues and I are busier than we were in March, there has been no pent-up overflow of people with crushing chest pain, debilitating shortness of breath or fevers and wet, rattling coughs.“It’s so weird,” a colleague remarked recently.

€œIt’s like those people have vanished.”I remembered my colleague’s observation when levitra yorum I read a recent study that suggested why those patients have never returned. #styln-briefing-block { font-family. Nyt-franklin,helvetica,arial,sans-serif.

That idea is at the heart of a fascinating new study of the differing effects of running and walking on the knee joint. Using motion capture and sophisticated computer modeling, the study confirms that running pummels knees more than walking does.

But in the process, the authors conclude, running likely also levitra cheap online fortifies and bulks up the cartilage, the rubbery tissue that cushions the ends of bones. The findings raise the beguiling possibility that, instead of harming knees, running might fortify them and help to stave off knee arthritis.Of course, the notion that running wrecks knees is widespread and entrenched. Almost anyone who runs is familiar with warnings from well-meaning, nonrunning family members, friends and strangers that their knees are doomed.This concern is not unwarranted.

Running involves substantial joint bending and pounding, which can fray the cushioning cartilage inside levitra cheap online the knee. Cartilage, which does not have its own blood supply, generally is thought to have little ability to repair itself when damaged or to change much at all after childhood. So, repeated running conceivably wears away fragile cartilage and almost inevitably should lead to crippling knee arthritis.But in real life, it does not.

Some runners levitra cheap online develop knee arthritis, but not all. As a group, in fact, runners may be statistically less likely to become arthritic than nonrunners.The question of why running spares so many runners’ knees has long intrigued Ross Miller, an associate professor of kinesiology at the University of Maryland in College Park. In earlier research, he and his colleagues had looked into whether running mechanics matter, by asking volunteers to walk and run along a track outfitted with plates to measure the forces generated with each step.The resulting data showed that people hit the ground harder while running, clobbering their knees far more with each stride.

But they also spent levitra cheap online more time aloft between strides, meaning they took fewer strides while covering the same distance as when walking. So, the cumulative forces moving through their knees over time should be about the same, the researchers concluded, whether someone walked or ran.But, recently, Dr. Miller had begun to doubt whether this finding really explained why running wasn’t wrecking more knees.

He knew that some recent studies with animals intimated that cartilage might be more resilient than levitra cheap online researchers previously had believed. In those studies, animals that ran tended to have thicker, healthier knee cartilage than comparable tissues from sedentary animals, suggesting that the active animals’ cartilage had changed in response to their running.Perhaps, Dr. Miller speculated, cartilage in human runners’ knees likewise might alter and adapt.To find out, he again asked a group of healthy young men and women to walk and run along a track containing force plates, while he and his colleagues filmed them.

The researchers then levitra cheap online computed the forces the volunteers had generated while strolling and running. Finally, they modeled what the future might hold for the volunteers’ knees.More specifically, they used the force-plate numbers, plus extensive additional data from past studies of biopsied cartilage pulled and pummeled in the lab until it fell apart and other sources to create computer simulations. They wanted to see what, theoretically, would happen to healthy knee cartilage if an adult walked for six kilometers (about 3.7 miles) every day for years, compared to if they walked for three kilometers and ran for another three kilometers each of those days.They also tested two additional theoretical situations.

For one, the researchers programmed in the possibility that people’s knee cartilage would slightly repair itself after repeated small damage from walking levitra cheap online or running — but not otherwise change. And for the last scenario, they presumed that the cartilage would actively remodel itself and adapt to the demands of moving, growing thicker and stronger, much as muscle does when we exercise.The models’ final results were eye-opening. According to the simulations, daily walkers faced about a 36 percent chance of developing arthritis by the age of 55, if the model did not include the possibility of the knee cartilage adapting or repairing itself.

That risk dropped to about 13 percent if cartilage were assumed to be able to repair or adapt, which is about what studies predict to be the real-world arthritis risk levitra cheap online for otherwise healthy people.The numbers for running were more worrisome. When the model assumed cartilage cannot change, the runners’ risk of eventual arthritis was a whopping 98 percent, declining only to 95 percent if the model factored in the possibility of cartilage repair. In effect, according to this scenario, the damage to cartilage from frequent running would overwhelm any ability of the tissue to fix itself.But if the model included the likelihood of the cartilage actively adapting — growing thicker and cushier — when people ran, the odds of runners developing arthritis fell to about 13 percent, the same as for healthy walkers.What these results suggest is that cartilage is malleable, Dr.

Ross says levitra cheap online. It must be able to sense the strains and slight damage from running and rebuild itself, becoming stronger. In this scenario, running bolsters cartilage health.Modeled results like these are theoretical, though, and limited.

They do not explain how cartilage remodels itself without a blood supply or if genetics, nutrition, body weight, knee injuries and other levitra cheap online factors affect individual arthritis risks. Such models also do not tell us if different distances, speeds or running forms would alter the outcomes. To learn more, we will need direct measures of molecular and other changes in living human cartilage after running, Dr.

Miller says, but such tests are difficult.Still, this study levitra cheap online may quiet some runners’ qualms — and those of their families and friends. €œIt looks like running is unlikely to cause knee arthritis by wearing out cartilage,” Dr. Ross says.Weathered, wiry and in his early 60s, the man stumbled into clinic, trailing cigarette smoke and clutching his chest.

Over the previous week, he had had fleeting episodes of chest pressure but stayed levitra cheap online away from the hospital.“I didn’t want to get the coronavirus,” he gasped as the nurses unbuttoned his shirt to get an EKG. Only when his pain had become relentless did he feel he had no choice but to come in.In pre-pandemic times, patients like him were routine at my Boston-area hospital. We saw them almost every day.

But for much of the levitra cheap online spring and summer, the halls and parking lots were eerily empty. I wondered if people were staying home and getting sicker, and I imagined that in a few months’ time these patients, once they became too ill to manage on their own, might flood the emergency rooms, wards and I.C.U.s, in a non-Covid wave.But more than seven months into the pandemic, there are still no lines of patients in the halls. While my colleagues and I are busier than we were in March, there has been no pent-up overflow of people with crushing chest pain, debilitating shortness of breath or fevers and wet, rattling coughs.“It’s so weird,” a colleague remarked recently.

€œIt’s like those people have vanished.”I remembered my colleague’s observation when I read a recent study that suggested why those patients have never levitra cheap online returned. #styln-briefing-block { font-family. Nyt-franklin,helvetica,arial,sans-serif.

IntroductionIn recent years, many studies have been published on new diagnostic possibilities and management approaches in cohorts of patients suspected to have a disorder/difference of sex development (DSD).1–13 Based on these studies, it has become clear that services and institutions still differ in the composition of the viagra vs cialis vs levitra forum multidisciplinary teams that provide care for patients who have a DSD.11 14 Several projects have now worked to resolve this variability in care. The European Cooperation in Science and Technology (EU COST) action BM1303 ‘A systematic elucidation of differences of sex development’ has been a platform to achieve European agreement on harmonisation of clinical management and laboratory practices.15–17 Another such initiative involved an update of the 2006 DSD consensus document by an international group of professionals and patient representatives.18 These initiatives have highlighted viagra vs cialis vs levitra forum how cultural and financial aspects and the availability of resources differ significantly between countries and societies, a situation that hampers supranational agreement on common diagnostic protocols. As only a few national guidelines have been published in international journals, comparison of these guidelines is difficult even though such a comparison is necessary to capture the differences and initiate actions to overcome them.

Nonetheless, four DSD (expert) centres located in the Netherlands and Flanders (the viagra vs cialis vs levitra forum Dutch-speaking Northern part of Belgium) have collaborated to produce a detailed guideline on diagnostics in DSD.19 This shows that a supranational guideline can be a reasonable approach for countries with similarly structured healthcare systems and similar resources. Within the guideline there is agreement that optimisation of expertise and care can be achieved through centralisation, for example, by limiting analysis of next-generation sequencing (NGS)-based diagnostic panels to only a few centres and by centralising pathological review of gonadal tissues. International networks such as the European Reference Network for viagra vs cialis vs levitra forum rare endocrine conditions (EndoERN), in which DSD is embedded, may facilitate the expansion of this kind of collaboration across Europe.This paper highlights key discussion points in the Dutch-Flemish guideline that have been insufficiently addressed in the literature thus far because they reflect evolving technologies or less visible stakeholders.

For example, prenatal observation of an atypical aspect of the genitalia indicating a possible DSD is becoming increasingly common, and we discuss appropriate counselling and a diagnostic approach for these cases, including the option of using NGS-based genetic testing. So far, little attention has been paid to this process.20 21 Furthermore, informing patients and/or their parents about atypical sex development and why this may warrant referral to viagra vs cialis vs levitra forum a specialised team may be challenging, especially for professionals with limited experience in DSD.22 23 Therefore, a section of the Dutch-Flemish guideline was written for these healthcare providers. Moreover, this enables DSD specialists to refer to the guideline when advising a referral.

Transition from the prenatal to the postnatal team and from the paediatric to the viagra vs cialis vs levitra forum adult team requires optimal communication between the specialists involved. Application of NGS-based techniques may lead to a higher diagnostic yield, providing a molecular genetic diagnosis in previously unsolved cases.16 We address the timing of this testing and the problems associated with this technique such as the interpretation of variants of unknown clinical significance (VUS). Similarly, histopathological interpretation and classification of removed gonadal tissue is challenging and would benefit from international viagra vs cialis vs levitra forum collaboration and centralisation of expertise.MethodsFor the guideline revision, an interdisciplinary multicentre group was formed with all members responsible for updating the literature for a specific part of the guideline.

Literature search in PubMed was not systematic, but rather intended to be broad in order to cover all areas and follow expert opinions. This approach is more in line with the Clinical Practice Advisory Document method described by Burke et al24 for guidelines involving genetic practice because it is often troublesome to substantiate such guidelines with sufficient evidence due to the rapid changes in testing methods, for example, gene viagra vs cialis vs levitra forum panels. All input provided by the group was synthesised by the chairperson (YvB), who also reviewed abstracts of papers on DSD published between 2010 and September 2017 for the guideline and up to October 2019 for this paper.

Abstracts had to be written in English and were identified using a broad range of Medical Subject Headings terms (eg, DSD, genetic, review, diagnosis, diagnostics, 46,XX DSD, 46,XY DSD, guideline, multidisciplinary care) viagra vs cialis vs levitra forum. Next, potentially relevant papers on diagnostic procedures in DSD were selected. Case reports were excluded, as were articles that were not open access or retrievable through viagra vs cialis vs levitra forum institutional access.

Based on this, a draft guideline was produced that was in line with the international principles of good diagnostic care in DSD. This draft was discussed by the writing committee and, after having obtained agreement on remaining points of viagra vs cialis vs levitra forum discussion, revised into a final draft. This version was sent to a broad group of professionals from academic centres and DSD teams whose members had volunteered to review the draft guideline.

After receiving and viagra vs cialis vs levitra forum incorporating their input, the final version was presented to the paediatric and genetic associations for approval. After approval by the members of the paediatric (NVK), clinical genetic (VKGN) and genetic laboratory (VKGL) associations, the guideline was published on their respective websites.19 Although Turner syndrome and Klinefelter syndrome are considered to be part of the DSD spectrum, they are not extensively discussed in this diagnostic guideline as guidelines dedicated to these syndromes already exist.25 26 However, some individuals with Turner syndrome or Klinefelter syndrome may present with ambiguous or atypical genitalia and may therefore initially follow the DSD diagnostic process.Guideline highlightsPrenatal settingPresentationThe most frequent prenatal presentation of a DSD condition is atypical genitalia found on prenatal ultrasound as an isolated finding or in combination with other structural anomalies. This usually occurs after the 20-week routine medical ultrasound for screening of congenital anomalies, but may also occur earlier, for example, when a commercial ultrasound is performed at the request of the parents.Another way DSD can be diagnosed before birth is when invasive prenatal genetic testing carried out for a different reason, for example, due to suspicion of other structural anomalies, reveals a discrepancy between the genotypic viagra vs cialis vs levitra forum sex and the phenotypic sex seen by ultrasound.

In certified laboratories, the possibility of a sample switch is extremely low but should be ruled out immediately. More often, the discrepancy will be due to sex-chromosome mosaicism or a true form of DSD.A situation now occurring with increasing frequency is a discrepancy between the genotypic sex revealed by viagra vs cialis vs levitra forum non-invasive prenatal testing (NIPT), which is now available to high-risk pregnant women in the Netherlands and to all pregnant women in Belgium, and later ultrasound findings. NIPT screens for CNVs in the fetus.

However, depending on legal restrictions and/or ethical considerations, the X and Y chromosomes are not always included viagra vs cialis vs levitra forum in NIPT analysis and reports. If the X and Y chromosomes are included, it is important to realise that the presence of a Y-chromosome does not necessarily imply male fetal development. At the time that NIPT is performed (usually 11–13 weeks), genital development cannot be reliably appreciated by ultrasound, so any discrepancy or atypical aspect of the genitalia will only be noticed later in pregnancy and should prompt further evaluation.Counselling and diagnosticsIf viagra vs cialis vs levitra forum a DSD is suspected, first-line sonographers and obstetricians should refer the couple to their colleague prenatal specialists working with or in a DSD team.

After confirming an atypical genital on ultrasound, the specialist team should offer the couple a referral for genetic counselling to discuss the possibility of performing invasive prenatal testing (usually an amniocentesis) to identify an underlying cause that fits the ultrasound findings.22 23 To enable the parents to make a well-informed decision, prenatal counselling should, in our opinion, include. Information on the ultrasound findings and the limitations of viagra vs cialis vs levitra forum this technique. The procedure(s) that can be followed, including the risks associated with an amniocentesis.

And the type viagra vs cialis vs levitra forum of information genetic testing can and cannot provide. Knowing which information has been provided and what words have been used by the prenatal specialist is very helpful for those involved in postnatal care.It is important that parents understand that the biological sex of a baby is determined by a complex interplay of chromosomes, genes and hormones, and thus that assessment of the presence or absence of a Y-chromosome alone is insufficient to assign the sex of their unborn child or, as in any unborn child, say anything about the child’s future gender identity.Expecting parents can be counselled by the clinical geneticist and the psychologist from the DSD team, although other DSD specialists can also be involved. The clinical geneticist should be experienced in prenatal counselling and well informed about the diagnostic possibilities given the limited time span in which test results need to be available to allow parents to make a well-informed decision about whether or not to viagra vs cialis vs levitra forum continue the pregnancy.

Termination of pregnancy can be considered, for instance, in a syndromic form of viagra vs cialis vs levitra forum DSD with multiple malformations, but when the DSD occurs as an apparently isolated condition, expecting parents may also consider termination of pregnancy, which, although considered controversial by some, is legal in Belgium and the Netherlands. The psychologist of the DSD team can support parents during and after pregnancy and help them cope with feelings of uncertainty and eventual considerations of a termination of pregnancy, as well as with practical issues, for example, how to inform others. The stress of not knowing exactly what the child’s genitalia will look like and uncertainty about the diagnosis, viagra vs cialis vs levitra forum treatment and prognosis cannot be avoided completely.

Parents are informed that if the postnatal phenotype is different from what was prenatally expected, the advice given about diagnostic testing can be adjusted accordingly, for example, if a hypospadias is milder than was expected based on prenatal ultrasound images. In our experience, parents appreciate having already spoken to some members of the DSD team during pregnancy and having a contact person before birth.After expert prenatal counselling, a significant number of viagra vs cialis vs levitra forum pregnant couples decline prenatal testing (personal experience IALG, MK, ABD, YvB, MC and HC-vdG). At birth, umbilical cord blood is a good source for (molecular) karyotyping and storage of DNA and can be obtained by the obstetrician, midwife or neonatologist.

The terminology used in communication with parents should be carefully chosen,22 23 and midwives and staff of neonatal and delivery units should be clearly instructed to use gender-neutral and non-stigmatising vocabulary (eg, ‘your viagra vs cialis vs levitra forum baby’) as long as sex assignment is pending.An algorithm for diagnostic evaluation of a suspected DSD in the prenatal situation is proposed in figure 1. When couples opt for invasive prenatal diagnosis, the genetic analysis usually involves an (SNP)-array. It was viagra vs cialis vs levitra forum recently estimated that >30% of individuals who have a DSD have additional structural anomalies, with cardiac and neurological anomalies and fetal growth restriction being particularly common.27 28 If additional anomalies are seen, the geneticist can consider specific gene defects that may underlie a known genetic syndrome or carry out NGS.

NGS-based techniques have also now made their appearance in prenatal diagnosis of congenital anomalies.29 30 Panels using these techniques can be specific for genes involved in DSD, or be larger panels covering multiple congenital anomalies, and are usually employed with trio-analysis to compare variants identified in the child with the parents’ genetics.29–31 Finding a genetic cause before delivery can help reduce parental stress in the neonatal period and speed up decisions regarding gender assignment. In such cases there viagra vs cialis vs levitra forum is no tight time limit, and we propose completing the analysis well before the expected delivery.Disorders/differences of sex development (DSD) in the prenatal setting.

NGS, next-generation sequencing.First contact by a professional less experienced in DSDWhereas most current guidelines start from the point when an individual has been referred to the DSD team,1 15 the Dutch-Flemish guideline dedicates a chapter to healthcare professionals less experienced in DSD as they are often the first to suspect or identify such a condition.

Apart from the paper of Indyk,7 little guidance is available for these professionals about how to act in such a situation. The chapter in the Dutch-Flemish guideline summarises the various clinical presentations that a DSD can have and provides information on how to communicate with parents and/or patients about the findings of the physical examination, the first-line investigations and the need for prompt referral to a specialised centre for further evaluation. Clinical examples are offered to illustrate some of these recurring situations.

The medical issues in DSD can be very challenging, and the social and psychological impact is high. For neonates with ambiguous genitalia, sex assignment is an urgent and crucial issue, and it is mandatory that parents are informed that it is possible to postpone registration of their child’s sex. In cases where sex assignment has already taken place, the message that the development of the gonads or genitalia is still atypical is complicated and distressing for patients and parents or carers.

A list of contact details for DSD centres and patient organisations in the Netherlands and Flanders is attached to the Dutch-Flemish guideline. Publishing such a list, either in guidelines or online, can help healthcare professionals find the nearest centres for consultations and provide patients and patient organisations with an overview of the centres where expertise is available.Timing and place of genetic testing using NGS-based gene panelsThe diagnostic workup that is proposed for 46,XX and 46,XY DSD is shown in figures 2 and 3, respectively. Even with the rapidly expanding molecular possibilities, a (family) history and a physical examination remain the essential first steps in the diagnostic process.

Biochemical and hormonal screening aim at investigating serum electrolytes, renal function and the hypothalamic-pituitary-gonadal and hypothalamic-pituitary-adrenal axes. Ultrasound screening of kidneys and internal genitalia, as well as establishing genotypic sex, should be accomplished within 48 hours and complete the baseline diagnostic work-up of a child born with ambiguous genitalia.1 16 32 3346,XX disorders/differences of sex development (DSD) in the postnatal setting.

Conventional karyotyping can be useful. NGS, next-generation sequencing.Very recently, a European position paper has been published focusing on the genetic workup of DSD.16 It highlights the limitations and drawbacks of NGS-based tests, which include the chance of missing subtle structural variants such as CNVs and mosaicism and the fact that NGS cannot detect methylation defects or other epigenetic changes.16 28 31 Targeted DNA analysis is preferred in cases where hormonal investigations suggest a block in steroidogenesis (eg, 11-β-hydroxylase deficiency, 21-hydroxylase deficiency), or in the context of a specific clinical constellation such as the often coincidental finding of Müllerian structures in a boy with normal external genitalia or cryptorchidism, that is, persistent Müllerian duct syndrome.33 34 Alternative tests should also be considered depending on the available information. Sometimes, a simple mouth swab for FISH analysis can detect mosaic XY/X in a male with hypospadias or asymmetric gonadal development or in a female with little or no Turner syndrome stigmata and a normal male molecular karyotyping profile or peripheral blood karyotype.

Such targeted testing avoids incidental findings and is cheaper and faster than analysis of a large NGS-based panel, although the cost difference is rapidly declining.However, due to the genetic and phenotypic heterogeneity of DSD conditions, the most cost-effective next steps in the majority of cases are whole exome sequencing followed by panel analysis of genes involved in genital development and function or trio-analysis of a large gene panel (such as a Mendeliome).16 35–38 Pretest genetic counselling involves discussing what kind of information will be reported to patients or parents and the chance of detecting VUS, and the small risk of incidental findings when analysing a DSD panel should be mentioned. Laboratories also differ in what class of variants they report.39 In our experience, the fear of incidental findings is a major reason why some parents refrain from genetic testing.Timing of the DSD gene panel analysis is also important. While some patients or parents prefer that all diagnostic procedures be performed as soon as possible, others need time to reflect on the complex information related to more extensive genetic testing and on its possible consequences.

If parents or patients do not consent to panel-based genetic testing, analysis of specific genes, such as WT1, should be considered when appropriate in view of the clinical consequences if a mutation is present (eg, clinical surveillance of renal function and screening for Wilms’ tumour in the case of WT1 mutations). Genes that are more frequently involved in DSD (eg, SRY, NR5A1) and that match the specific clinical and hormonal features in a given patient could also be considered for sequencing. Targeted gene analysis may also be preferred in centres located in countries that do not have the resources or technical requirements to perform NGS panel-based genetic testing.

Alternatively, participation by these centres in international collaborative networks may allow them to outsource the molecular genetic workup abroad.Gene panels differ between centres and are regularly updated based on scientific progress. A comparison of DSD gene panels used in recent studies can be found at https://www.nature.com/articles/s41574-018-0010-8%23Sec46.15 The panels currently used at the coauthors’ institutions can be found on their respective websites. Given the pace of change, it is important to regularly consider repeating analysis in patients with an unexplained DSD, for example, when they transition into adult care or when they move from one centre to another.

This also applies to patients in whom a clinical diagnosis has never been genetically confirmed. Confusion may arise when the diagnosis cannot be confirmed or when a mutation is identified in a different gene, for example, NR5A1 in someone with a clinical diagnosis of CAIS that has other consequences for relatives. Hence, new genetic counselling should always accompany new diagnostic endeavours.Class 3 variants and histopathological examinationsThe rapidly evolving diagnostic possibilities raise new questions.

What do laboratories report?. How should we deal with the frequent findings of mainly unique VUS or class 3 variants (ACMG recommendation) in the many different DSD-related genes in the diagnostic setting?. Reporting VUS can be a source of uncertainty for parents, but not reporting these variants precludes further investigations to determine their possible pathogenicity.

It can also be difficult to prove variant pathogenicity, both on gene-level and variant-level.39 Moreover, given the gonad-specific expression of some genes and the variable phenotypic spectrum and reduced penetrance, segregation analysis is not always informative. A class 3 variant that does not fit the clinical presentation may be unrelated to the observed phenotype, but it could also represent a newly emerging phenotype. This was recently demonstrated by the identification of the NR5A1 mutation, R92W, in individuals with 46,XX testicular and ovotesticular DSD.40 This gene had previously been associated with 46,XY DSD.

In diagnostic laboratories, there is usually no capacity or expertise to conduct large-scale functional studies to determine pathogenicity of these unique class 3 VUS in the different genes involved in DSD. Functional validation of variants identified in novel genes may be more attractive in a research context. However, for individual families with VUS in well-established DSD genes such as AR or HSD17B3, functional analysis may provide a confirmed diagnosis that implies for relatives the option of undergoing their own DNA analysis and estimating the genetic risk of their own future offspring.

This makes genetic follow-up important in these cases and demonstrates the usefulness of international databases and networks and the centralisation of functional studies of genetic variants in order to reduce costs and maximise expertise.The same is true for histopathological description, germ-cell tumour risk assessment in specific forms of DSD and classification of gonadal samples. Germ-cell tumour risk is related to the type of DSD (among other factors), but it is impossible to make risk estimates in individual cases.41–44 Gonadectomy may be indicated in cases with high-risk dysgenetic abdominal gonads that cannot be brought into a stable superficial (ie, inguinal, labioscrotal) position that allows clinical or radiological surveillance, or to avoid virilisation due to 5-alpha reductase deficiency in a 46,XY girl with a stable female gender identity.45 Pathological examination of DSD gonads requires specific expertise. For example, the differentiation between benign germ cell abnormalities, such as delayed maturation and (pre)malignant development of germ cells, is crucial for clinical management but can be very troublesome.46 Centralised pathological examination of gonadal biopsy and gonadectomy samples in one centre, or a restricted number of centres, on a national scale can help to overcome the problem of non-uniform classification and has proven feasible in the Netherlands and Belgium.

We therefore believe that uniform assessment and classification of gonadal differentiation patterns should also be addressed in guidelines on DSD management.International databases of gonadal tissues are crucial for learning more about the risk of malignancy in different forms of DSD, but they are only reliable if uniform criteria for histological classification are strictly applied.46 These criteria could be incorporated in many existing networks such as the I-DSD consortium, the Disorders of Sex Development Translational Research Network, the European Reference Network on Urogenital Diseases (eUROGEN), the EndoERN and COST actions.15–17 47Communication at the transition from paediatric to adult carePaediatric and adult teams need to collaborate closely to facilitate a well-organised transition from paediatric to adult specialist care.15 48–50 Both teams need to exchange information optimally and should consider transition as a longitudinal process rather than a fixed moment in time. Age-appropriate information is key at all ages, and an overview of topics to be discussed at each stage is described by Cools et al.15 Table 1 shows an example of how transition can be organised.View this table:Table 1 Example of transition table as used in the DSD clinic of the Erasmus Medical CenterPsychological support and the continued provision of information remains important for individuals with a DSD at all ages.15 22 In addition to the information given by the DSD team members, families and patients can benefit from resources such as support groups and information available on the internet.47 Information available online should be checked for accuracy and completeness when referring patients and parents to internet sites.Recommendations for future actionsMost guidelines and articles on the diagnosis and management of DSD are aimed at specialists and are only published in specialist journals or on websites for endocrinologists, urologists or geneticists. Yet there is a need for guidelines directed towards first-line and second-line healthcare workers that summarise the recommendations about the first crucial steps in the management of DSD.

These should be published in widely available general medical journals and online, along with a national list of DSD centres. Furthermore, DSD (expert) centres should provide continuous education to all those who may be involved in the identification of individuals with a DSD in order to enable these healthcare professionals to recognise atypical genitalia, to promptly refer individuals who have a DSD and to inform the patient and parents about this and subsequent diagnostic procedures.As DSD continues to be a rare condition, it will take time to evaluate the effects of having such a guideline on the preparedness of first-line and second-line healthcare workers to recognise DSD conditions. One way to evaluate this might be the development and use of questionnaires asking patients, carers and families and referring physicians how satisfied they were with the initial medical consultation and referral and what could be improved.

A helpful addition to existing international databases that collect information on genetic variations would be a list of centres that offer suitable functional studies for certain genes, ideally covering the most frequently mutated genes (at minimum).Patient organisations can also play an important role in informing patients about newly available diagnostic or therapeutic strategies and options, and their influence and specific role has now been recognised and discussed in several publications.17 47 However, it should be kept in mind that these organisations do not represent all patients, as a substantial number of patients and parents are not member of such an organisation.Professionals have to provide optimal medical care based on well-established evidence, or at least on broad consensus. Yet not everything can be regulated by recommendations and guidelines. Options, ideas and wishes should be openly discussed between professionals, patients and families within their confidential relationship.

This will enable highly individualised holistic care tailored to the patient’s needs and expectations. Once they are well-informed of all available options, parents and/or patients can choose what they consider the optimal care for their children or themselves.15 16ConclusionThe Dutch-Flemish guideline uniquely addresses some topics that are under-represented in the literature, thus adding some key aspects to those addressed in recent consensus papers and guidelines.15–17 33 47As more children with a DSD are now being identified prenatally, and the literature on prenatal diagnosis of DSD remains scarce,20 21 we propose a prenatal diagnostic algorithm and emphasise the importance of having a prenatal specialist involved in or collaborating with DSD (expert) centres.We also stress that good communication between all involved parties is essential. Professionals should be well informed about protocols and communication.

Collaboration between centres is necessary to optimise aspects of care such as uniform interpretation of gonadal pathology and functional testing of class 3 variants found by genetic testing. Guidelines can provide a framework within which individualised patient care should be discussed with all stakeholders.AcknowledgmentsThe authors would like to thank the colleagues of the DSD teams for their input in and critical reading of the Dutch-Flemish guideline.

Three of the authors of this publication are members of the European Reference Network for rare endocrine diseases—Project ID 739543.IntroductionEndometrial cancer is the most common gynaecological malignancy in the developed world.1 Its incidence has risen over the last two decades as a consequence of the ageing population, fewer hysterectomies for benign disease and the obesity epidemic. In the USA, it is estimated that women have a 1 in 35 lifetime risk of endometrial cancer, and in contrast to cancers of most other sites, cancer-specific mortality has risen by approximately 2% every year since 2008 related to the rapidly rising incidence.2Endometrial cancer has traditionally been classified into type I and type II based on morphology.3 The more common subtype, type I, is mostly comprised of endometrioid tumours and is oestrogen-driven, arises from a hyperplastic endometrium, presents at an early stage and has an excellent 5 year survival rate.4 By contrast, type II includes non-endometrioid tumours, specifically serous, carcinosarcoma and clear cell subtypes, which are biologically aggressive tumours with a poor prognosis that are often diagnosed at an advanced stage.5 Recent efforts have focused on a molecular classification system for more accurate categorisation of endometrial tumours into four groups with distinct prognostic profiles.6 7The majority of endometrial cancers arise through the interplay of familial, genetic and lifestyle factors.

Two inherited cancer predisposition syndromes, Lynch syndrome and the much rarer Cowden syndrome, substantially increase the lifetime risk of endometrial cancer, but these only account for around 3–5% of cases.8–10 Having first or second degree relative(s) with endometrial or colorectal cancer increases endometrial cancer risk, although a large European twin study failed to demonstrate a strong heritable link.11 The authors failed to show that there was greater concordance in monozygotic than dizygotic twins, but the study was based on relatively small numbers of endometrial cancers. Lu and colleagues reported an association between common single nucleotide polymorphisms (SNPs) and endometrial cancer risk, revealing the potential role of SNPs in explaining part of the risk in both the familial and general populations.12 Thus far, many SNPs have been reported to modify susceptibility to endometrial cancer. However, much of this work predated genome wide association studies and is of variable quality.

Understanding genetic predisposition to endometrial cancer could facilitate personalised risk assessment with a view to targeted prevention and screening interventions.13 This emerged as the most important unanswered research question in endometrial cancer according to patients, carers and healthcare professionals in our recently completed James Lind Womb Cancer Alliance Priority Setting Partnership.14 It would be particularly useful for non-endometrioid endometrial cancers, for which advancing age is so far the only predictor.15We therefore conducted a comprehensive systematic review of the literature to provide an overview of the relationship between SNPs and endometrial cancer risk. We compiled a list of the most robust endometrial cancer-associated SNPs. We assessed the applicability of this panel of SNPs with a theoretical polygenic risk score (PRS) calculation.

We also critically appraised the meta-analyses investigating the most frequently reported SNPs in MDM2. Finally, we described all SNPs reported within genes and pathways that are likely involved in endometrial carcinogenesis and metastasis.MethodsOur systematic review follows the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) collaboration 2009 recommendations. The registered protocol is available through PROSPERO (CRD42018091907).16Search strategyWe searched Embase, MEDLINE and Cumulative Index to Nursing and Allied Health Literature (CINAHL) databases via the Healthcare Databases Advanced Search (HDAS) platform, from 2007 to 2018, to identify studies reporting associations between polymorphisms and endometrial cancer risk.

Key words including MeSH (Medical Subject Heading) terms and free-text words were searched in both titles and abstracts. The following terms were used. €œendomet*”,“uter*”, “womb”, “cancer(s)”, “neoplasm(s)”, “endometrium tumour”, “carcinoma”, “adenosarcoma”, “clear cell carcinoma”, “carcinosarcoma”, “SNP”, “single nucleotide polymorphism”, “GWAS”, and “genome-wide association study/ies”.

No other restrictions were applied. The search was repeated with time restrictions between 2018 and June 2019 to capture any recent publications.Eligibility criteriaStudies were selected for full-text evaluation if they were primary articles investigating a relationship between endometrial cancer and SNPs. Study outcome was either the increased or decreased risk of endometrial cancer relative to controls reported as an odds ratio (OR) with corresponding 95% confidence intervals (95% CIs).Study selectionThree independent reviewers screened all articles uploaded to a screening spreadsheet developed by Helena VonVille.17 Disagreements were resolved by discussion.

Chronbach’s α score was calculated between reviewers and indicated high consistency at 0.92. Case–control, prospective and retrospective studies, genome-wide association studies (GWAS), and both discovery and validation studies were selected for full-text evaluation. Non-English articles, editorials, conference abstracts and proceedings, letters and correspondence, case reports and review articles were excluded.Candidate-gene studies with at least 100 women and GWAS with at least 1000 women in the case arm were selected to ensure reliability of the results, as explained by Spencer et al.18 To construct a panel of up to 30 SNPs with the strongest evidence of association, those with the strongest p values were selected.

For the purpose of an SNP panel, articles utilising broad European or multi-ethnic cohorts were selected. Where overlapping populations were identified, the most comprehensive study was included.Data extraction and synthesisFor each study, the following data were extracted. SNP ID, nearby gene(s)/chromosome location, OR (95% CI), p value, minor or effect allele frequency (MAF/EAF), EA (effect allele) and OA (other allele), adjustment, ethnicity and ancestry, number of cases and controls, endometrial cancer type, and study type including discovery or validation study and meta-analysis.

For risk estimates, a preference towards most adjusted results was applied. For candidate-gene studies, a standard p value of<0.05 was applied and for GWAS a p value of <5×10-8, indicating genome-wide significance, was accepted as statistically significant. However, due to the limited number of SNPs with p values reaching genome-wide significance, this threshold was then lowered to <1×10-5, allowing for marginally significant SNPs to be included.

As shown by Mavaddat et al, for breast cancer, SNPs that fall below genome-wide significance may still be useful for generating a PRS and improving the models.19We estimated the potential value of a PRS based on the most significant SNPs by comparing the predicted risk for a woman with a risk score in the top 1% of the distribution to the mean predicted risk. Per-allele ORs and MAFs were taken from the publications and standard errors (SEs) for the lnORs were derived from published 95% CIs. The PRS was assumed to have a Normal distribution, with mean 2∑βipI and SE, σ, equal to √2∑βi2pI(1−pi), according to the binomial distribution, where the summation is over all SNPs in the risk score.

Hence the relative risk (RR) comparing the top 1% of the distribution to the mean is given by exp(Z0.01σ), where Z is the inverse of the standard normal cumulative distribution.ResultsThe flow chart of study selection is illustrated in figure 1. In total, 453 text articles were evaluated and, of those, 149 articles met our inclusion criteria. One study was excluded from table 1, for having an Asian-only population, as this would make it harder to compare with the rest of the results which were all either multi-ethnic or Caucasian cohorts, as stated in our inclusion criteria for the SNP panel.20 Any SNPs without 95% CIs were also excluded from any downstream analysis.

Additionally, SNPs in linkage disequilibrium (r2 >0.2) with each other were examined, and of those in linkage disequilibrium, the SNP with strongest association was reported. Per allele ORs were used unless stated otherwise.View this table:Table 1 List of top SNPs most likely to contribute to endometrial cancer risk identified through systematic review of recent literature21–25Study selection flow diagram. *Reasons.

Doi:10.1371/journal.pmed1000097.Top SNPs associated with endometrial cancer riskFollowing careful interpretation of the data, 24 independent SNPs with the lowest p values that showed the strongest association with endometrial cancer were obtained (table 1).21–25 These SNPs are located in or around genes coding for transcription factors, cell growth and apoptosis regulators, and enzymes involved in the steroidogenesis pathway. All the SNPs presented here were reported on the basis of a GWAS or in one case, an exome-wide association study, and hence no SNPs from candidate-gene studies made it to the list. This is partly due to the nature of larger GWAS providing more comprehensive and powered results as opposed to candidate gene studies.

Additionally, a vast majority of SNPs reported by candidate-gene studies were later refuted by large-scale GWAS such as in the case of TERT and MDM2 variants.26 27 The exception to this is the CYP19 gene, where candidate-gene studies reported an association between variants in this gene with endometrial cancer in both Asian and broad European populations, and this association was more recently confirmed by large-scale GWAS.21 28–30 Moreover, a recent article authored by O’Mara and colleagues reviewed the GWAS that identified most of the currently known SNPs associated with endometrial cancer.31Most of the studies represented in table 1 are GWAS and the majority of these involved broad European populations. Those having a multi-ethnic cohort also consisted primarily of broad European populations. Only four of the variants in table 1 are located in coding regions of a gene, or in regulatory flanking regions around the gene.

Thus, most of these variants would not be expected to cause any functional effects on the gene or the resulting protein. An eQTL search using GTEx Portal showed that some of the SNPs are significantly associated (p<0.05) with modified transcription levels of the respective genes in various tissues such as prostate (rs11263761), thyroid (rs9668337), pituitary (rs2747716), breast mammary (rs882380) and testicular (rs2498794) tissue, as summarised in table 2.View this table:Table 2 List of eQTL hits for the selected panel of SNPsThe only variant for which there was an indication of a specific association with non-endometrioid endometrial cancer was rs148261157 near the BCL11A gene. The A allele of this SNP had a moderately higher association in the non-endometrioid arm (OR 1.64, 95% CI 1.32 to 2.04.

P=9.6×10-6) compared with the endometrioid arm (OR 1.25, 95% CI 1.14 to 1.38. P=4.7×10-6).21Oestrogen receptors α and β encoded by ESR1 and ESR2, respectively, have been extensively studied due to the assumed role of oestrogens in the development of endometrial cancer. O’Mara et al reported a lead SNP (rs79575945) in the ESR1 region that was associated with endometrial cancer (p=1.86×10-5).24 However, this SNP did not reach genome-wide significance in a more recent larger GWAS.21 No statistically significant associations have been reported between endometrial cancer and SNPs in the ESR2 gene region.AKT is an oncogene linked to endometrial carcinogenesis.

It is involved in the PI3K/AKT/mTOR pro-proliferative signalling pathway to inactivate apoptosis and allow cell survival. The A allele of rs2494737 and G allele of rs2498796 were reported to be associated with increased and decreased risk of endometrial cancer in 2016, respectively.22 30 However, this association was not replicated in a larger GWAS in 2018.21 Nevertheless, given the previous strong indications, and biological basis that could explain endometrial carcinogenesis, we decided to include an AKT1 variant (rs2498794) in our results.PTEN is a multi-functional tumour suppressor gene that regulates the AKT/PKB signalling pathway and is commonly mutated in many cancers including endometrial cancer.32 Loss-of-function germline mutations in PTEN are responsible for Cowden syndrome, which exerts a lifetime risk of endometrial cancer of up to 28%.9 Lacey and colleagues studied SNPs in the PTEN gene region. However, none showed significant differences in frequency between 447 endometrial cancer cases and 439 controls of European ancestry.33KRAS mutations are known to be present in endometrial cancer.

These can be activated by high levels of KLF5 (transcriptional activator). Three SNPs have been identified in or around KLF5 that are associated with endometrial cancer. The G allele of rs11841589 (OR 1.15, 95% CI 1.11 to 1.21.

P=4.83×10-11), the A allele of rs9600103 (OR 1.23, 95% CI 1.16 to 1.30. P=3.76×10-12) and C allele of rs7981863 (OR 1.16, 95% CI 1.12 to 1.20. P=2.70×10-17) have all been found to be associated with an increased likelihood of endometrial cancer in large European cohorts.21 30 34 It is worth noting that these SNPs are not independent, and hence they quite possibly tag the same causal variant.The MYC family of proto-oncogenes encode transcription factors that regulate cell proliferation, which can contribute to cancer development if dysregulated.

The recent GWAS by O’Mara et al reported three SNPs within the MYC region that reached genome-wide significance with conditional p values reaching at least 5×10–8.35To test the utility of these SNPs as predictive markers, we devised a theoretical PRS calculation using the log ORs and EAFs per SNP from the published data. The results were very encouraging with an RR of 3.16 for the top 1% versus the mean, using all the top SNPs presented in table 1 and 2.09 when using only the SNPs that reached genome-wide significance (including AKT1).Controversy surrounding MDM2 variant SNP309MDM2 negatively regulates tumour suppressor gene TP53, and as such, has been extensively studied in relation to its potential role in predisposition to endometrial cancer. Our search identified six original studies of the association between MDM2 SNP rs2279744 (also referred to as SNP309) and endometrial cancer, all of which found a statistically significant increased risk per copy of the G allele.

Two more original studies were identified through our full-text evaluation. However, these were not included here as they did not meet our inclusion criteria—one due to small sample size, the other due to studying rs2279744 status dependent on another SNP.36 37 Even so, the two studies were described in multiple meta-analyses that are listed in table 3. Different permutations of these eight original studies appear in at least eight published meta-analyses.

However, even the largest meta-analysis contained <2000 cases (table 3)38View this table:Table 3 Characteristics of studies that examined MDM2 SNP rs2279744In comparison, a GWAS including nearly 13 000 cases found no evidence of an association with OR and corresponding 95% CI of 1.00 (0.97 to 1.03) and a p value of 0.93 (personal communication).21 Nevertheless, we cannot completely rule out a role for MDM2 variants in endometrial cancer predisposition as the candidate-gene studies reported larger effects in Asians, whereas the GWAS primarily contained participants of European ancestry. There is also some suggestion that the SNP309 variant is in linkage disequilibrium with another variant, SNP285, which confers an opposite effect.It is worth noting that the SNP285C/SNP309G haplotype frequency was observed in up to 8% of Europeans, thus requiring correction for the confounding effect of SNP285C in European studies.39 However, aside from one study conducted by Knappskog et al, no other study including the meta-analyses corrected for the confounding effect of SNP285.40 Among the studies presented in table 3, Knappskog et al (2012) reported that after correcting for SNP285, the OR for association of this haplotype with endometrial cancer was much lower, though still significant. Unfortunately, the meta-analyses which synthesised Knappskog et al (2012), as part of their analysis, did not correct for SNP285C in the European-based studies they included.38 41 42 It is also concerning that two meta-analyses using the same primary articles failed to report the same result, in two instances.38 42–44DiscussionThis article represents the most comprehensive systematic review to date, regarding critical appraisal of the available evidence of common low-penetrance variants implicated in predisposition to endometrial cancer.

We have identified the most robust SNPs in the context of endometrial cancer risk. Of those, only 19 were significant at genome-wide level and a further five were considered marginally significant. The largest GWAS conducted in this field was the discovery- and meta-GWAS by O’Mara et al, which utilised 12 096 cases and 108 979 controls.21 Despite the inclusion of all published GWAS and around 5000 newly genotyped cases, the total number did not reach anywhere near what is currently available for other common cancers such as breast cancer.

For instance, BCAC (Breast Cancer Association Consortium) stands at well over 200 000 individuals with more than half being cases, and resulted in identification of ~170 SNPs in relation to breast cancer.19 45 A total of 313 SNPs including imputations were then used to derive a PRS for breast cancer.19 Therefore, further efforts should be directed to recruit more patients, with deep phenotypic clinical data to allow for relevant adjustments and subgroup analyses to be conducted for better precision.A recent pre-print study by Zhang and colleagues examined the polygenicity and potential for SNP-based risk prediction for 14 common cancers, including endometrial cancer, using available summary-level data from European-ancestry datasets.46 They estimated that there are just over 1000 independent endometrial cancer susceptibility SNPs, and that a PRS comprising all such SNPs would have an area under the receiver-operator curve of 0.64, similar to that predicted for ovarian cancer, but lower than that for the other cancers in the study. The modelling in the paper suggests that an endometrial cancer GWAS double the size of the current largest study would be able to identify susceptibility SNPs together explaining 40% of the genetic variance, but that in order to explain 75% of the genetic variance it would be necessary to have a GWAS comprising close to 150 000 cases and controls, far in excess of what is currently feasible.We found that the literature consists mainly of candidate-gene studies with small sample sizes, meta-analyses reporting conflicting results despite using the same set of primary articles, and multiple reports of significant SNPs that have not been validated by any larger GWAS. The candidate-gene studies were indeed the most useful and cheaper technique available until the mid to late 2000s.

However, a lack of reproducibility (particularly due to population stratification and reporting bias), uncertainty of reported associations, and considerably high false discovery rates make these studies much less appropriate in the post-GWAS era. Unlike the candidate-gene approach, GWAS do not require prior knowledge, selection of genes or SNPs, and provide vast amounts of data. Furthermore, both the genotyping process and data analysis phases have become cheaper, the latter particularly due to faster and open-access pre-phasing and imputation tools being made available.It is clear from table 1 that some SNPs were reported with wide 95% CI, which can be directly attributed to small sample sizes particularly when restricting the cases to non-endometrioid histology only, low EAF or poor imputation quality.

Thus, these should be interpreted with caution. Additionally, most of the SNPs reported by candidate-gene studies were not detected by the largest GWAS to date conducted by O’Mara et al.21 However, this does not necessarily mean that the possibility of those SNPs being relevant should be completely dismissed. Moreover, meta-analyses were attempted for other variants.

However, these showed no statistically significant association and many presented with high heterogeneity between the respective studies (data not shown). Furthermore, as many studies utilised the same set of cases and/or controls, conducting a meta-analysis was not possible for a good number of SNPs. It is therefore unequivocal that the literature is crowded with numerous small candidate-gene studies and conflicting data.

This makes it particularly hard to detect novel SNPs and conduct meaningful meta-analyses.We found convincing evidence for 19 variants that indicated the strongest association with endometrial cancer, as shown in table 1. The associations between endometrial cancer and variants in or around HNF1B, CYP19A1, SOX4, MYC, KLF and EIF2AK found in earlier GWAS were then replicated in the latest and largest GWAS. These SNPs showed promising potential in a theoretical PRS we devised based on published data.

Using all 24 or genome-wide significant SNPs only, women with a PRS in the top 1% of the distribution would be predicted to have a risk of endometrial cancer 3.16 and 2.09 times higher than the mean risk, respectively.However, the importance of these variants and relevance of the proximate genes in a functional or biological context is challenging to evaluate. Long distance promoter regulation by enhancers may disguise the genuine target gene. In addition, enhancers often do not loop to the nearest gene, further complicating the relevance of nearby gene(s) to a GWAS hit.

In order to elucidate biologically relevant candidate target genes in endometrial cancer, O’Mara et al looked into promoter-associated chromatin looping using a modern HiChIP approach.47 The authors utilised normal and tumoural endometrial cell lines for this analysis which showed significant enrichment for endometrial cancer heritability, with 103 candidate target genes identified across the 13 risk loci identified by the largest ECAC GWAS. Notable genes identified here were CDKN2A and WT1, and their antisense counterparts. The former was reported to be nearby of rs1679014 and the latter of rs10835920, as shown in table 1.

Moreover, of the 36 candidate target genes, 17 were found to be downregulated while 19 were upregulated in endometrial tumours.The authors also investigated overlap between the 13 endometrial cancer risk loci and top eQTL variants for each target gene.47 In whole blood, of the two particular lead SNPs, rs8822380 at 17q21.32 was a top eQTL for SNX11 and HOXB2, whereas rs937213 at 15q15.1 was a top eQTL for SRP14. In endometrial tumour, rs7579014 at 2p16.1 was found to be a top eQTL for BCL11A. This is particularly interesting because BCL11A was the only nearby/candidate gene that had a GWAS association reported in both endometrioid and non-endometrioid subtypes.

The study looked at protein–protein interactions between endometrial cancer drivers and candidate target gene products. Significant interactions were observed with TP53 (most significant), AKT, PTEN, ESR1 and KRAS, among others. Finally, when 103 target candidate genes and 387 proteins were combined together, 462 pathways were found to be significantly enriched.

Many of these are related to gene regulation, cancer, obesity, insulinaemia and oestrogen exposure. This study clearly showed a potential biological relevance for some of the SNPs reported by ECAC GWAS in 2018.Most of the larger included studies used cohorts primarily composed of women of broad European descent. Hence, there are negligible data available for other ethnicities, particularly African women.

This is compounded by the lack of reference genotype data available for comparative analysis, making it harder for research to be conducted in ethnicities other than Europeans. This poses a problem for developing risk prediction models that are equally valuable and predictive across populations. Thus, our results also are of limited applicability to non-European populations.Furthermore, considering that non-endometrioid cases comprise a small proportion (~20%) of all endometrial cancer cases, much larger cohort sizes are needed to detect any genuine signals for non-endometrioid tumours.

Most of the evaluated studies looked at either overall/mixed endometrial cancer subtypes or endometrioid histology, and those that looked at variant associations with non-endometrioid histology were unlikely to have enough power to detect any signal with statistical significance. This is particularly concerning because non-endometrioid subtypes are biologically aggressive tumours with a much poorer prognosis that contribute disproportionately to mortality from endometrial cancer. It is particularly important that attempts to improve early detection and prevention of endometrial cancer focus primarily on improving outcomes from these subtypes.

It is also worth noting that, despite the current shift towards a molecular classification of endometrial cancer, most studies used the overarching classical Bokhman’s classification system, type I versus type II, or no histological classification system at all. Therefore, it is important to create and follow a standardised and comprehensive classification system for reporting tumour subtypes for future studies.This study compiled and presented available information for an extensively studied, yet unproven in large datasets, SNP309 variant in MDM2. Currently, there is no convincing evidence for an association between this variant and endometrial cancer risk.

Additionally, of all the studies, only one accounted for the opposing effect of a nearby variant SNP285 in their analyses. Thus, we conclude that until confirmed by a sufficiently large GWAS, this variant should not be considered significant in influencing the risk of endometrial cancer and therefore not included in a PRS. This is also true for the majority of the SNPs reported in candidate-gene studies, as the numbers fall far short of being able to detect genuine signals.This systematic review presents the most up-to-date evidence for endometrial cancer susceptibility variants, emphasising the need for further large-scale studies to identify more variants of importance, and validation of these associations.

Until data from larger and more diverse cohorts are available, the top 24 SNPs presented here are the most robust common genetic variants that affect endometrial cancer risk. The multiplicative effects of these SNPs could be used in a PRS to allow personalised risk prediction models to be developed for targeted screening and prevention interventions for women at greatest risk of endometrial cancer..

IntroductionIn recent years, many studies have been published on new diagnostic possibilities and management approaches in cohorts of patients suspected to have a disorder/difference of sex development (DSD).1–13 Based on these studies, it has become clear that services and institutions still differ in the composition of the multidisciplinary teams that provide care for patients who have a DSD.11 14 Several levitra cheap online projects have now worked to resolve this http://sw.keimfarben.de/buy-generic-levitra-australia/ variability in care. The European Cooperation in Science and Technology (EU COST) action BM1303 ‘A systematic elucidation of differences of sex development’ has been a platform to achieve European agreement on harmonisation of clinical management and laboratory practices.15–17 Another such initiative involved an update of the 2006 DSD consensus document by an levitra cheap online international group of professionals and patient representatives.18 These initiatives have highlighted how cultural and financial aspects and the availability of resources differ significantly between countries and societies, a situation that hampers supranational agreement on common diagnostic protocols. As only a few national guidelines have been published in international journals, comparison of these guidelines is difficult even though such a comparison is necessary to capture the differences and initiate actions to overcome them.

Nonetheless, four DSD (expert) centres located in the Netherlands and Flanders (the Dutch-speaking Northern part of Belgium) have collaborated levitra cheap online to produce a detailed guideline on diagnostics in DSD.19 This shows that a supranational guideline can be a reasonable approach for countries with similarly structured healthcare systems and similar resources. Within the guideline there is agreement that optimisation of expertise and care can be achieved through centralisation, for example, by limiting analysis of next-generation sequencing (NGS)-based diagnostic panels to only a few centres and by centralising pathological review of gonadal tissues. International networks levitra cheap online such as the European Reference Network for rare endocrine conditions (EndoERN), in which DSD is embedded, may facilitate the expansion of this kind of collaboration across Europe.This paper highlights key discussion points in the Dutch-Flemish guideline that have been insufficiently addressed in the literature thus far because they reflect evolving technologies or less visible stakeholders.

For example, prenatal observation of an atypical aspect of the genitalia indicating a possible DSD is becoming increasingly common, and we discuss appropriate counselling and a diagnostic approach for these cases, including the option of using NGS-based genetic testing. So far, little attention has been paid to this process.20 21 Furthermore, informing patients and/or their parents about atypical sex development and why this may warrant referral to a specialised team may be challenging, especially for professionals with limited experience in DSD.22 23 Therefore, a section of levitra cheap online the Dutch-Flemish guideline was written for these healthcare providers. Moreover, this enables DSD specialists to refer to the guideline when advising a referral.

Transition from the prenatal to the postnatal team and from the paediatric to the adult team requires optimal levitra cheap online communication between the specialists involved. Application of NGS-based techniques may lead to a higher diagnostic yield, providing a molecular genetic diagnosis in previously unsolved cases.16 We address the timing of this testing and the problems associated with this technique such as the interpretation of variants of unknown clinical significance (VUS). Similarly, histopathological interpretation and classification of removed gonadal tissue is challenging and would benefit from international collaboration and centralisation of expertise.MethodsFor the guideline revision, an levitra cheap online interdisciplinary multicentre group was formed with all members responsible for updating the literature for a specific part of the guideline.

Literature search in PubMed was not systematic, but rather intended to be broad in order to cover all areas and follow expert opinions. This approach is more in line with the Clinical Practice Advisory Document method described by Burke et al24 for guidelines involving genetic practice because it is often troublesome to substantiate such guidelines with sufficient evidence due to the levitra cheap online rapid changes in testing methods, for example, gene panels. All input provided by the group was synthesised by the chairperson (YvB), who also reviewed abstracts of papers on DSD published between 2010 and September 2017 for the guideline and up to October 2019 for this paper.

Abstracts had to be written in English and were identified using a broad range of Medical Subject Headings terms (eg, DSD, levitra cheap online genetic, review, diagnosis, diagnostics, 46,XX DSD, 46,XY DSD, guideline, multidisciplinary care). Next, potentially relevant papers on diagnostic procedures in DSD were selected. Case reports were excluded, as were articles that were not open levitra cheap online access or retrievable through institutional access.

Based on this, a draft guideline was produced that was in line with the international principles of good diagnostic care in DSD. This draft was discussed by the writing committee and, after having obtained levitra cheap online agreement on remaining points of discussion, revised into a final draft. This version was sent to a broad group of professionals from academic centres and DSD teams whose members had volunteered to review the draft guideline.

After receiving and incorporating levitra cheap online their input, the final version was presented to the paediatric and genetic associations for approval. After approval by the members of the paediatric (NVK), clinical genetic (VKGN) and genetic laboratory (VKGL) associations, the guideline was published on their respective websites.19 Although Turner syndrome and Klinefelter syndrome are considered to be part of the DSD spectrum, they are not extensively discussed in this diagnostic guideline as guidelines dedicated to these syndromes already exist.25 26 However, some individuals with Turner syndrome or Klinefelter syndrome may present with ambiguous or atypical genitalia and may therefore initially follow the DSD diagnostic process.Guideline highlightsPrenatal settingPresentationThe most frequent prenatal presentation of a DSD condition is atypical genitalia found on prenatal ultrasound as an isolated finding or in combination with other structural anomalies. This usually occurs after the 20-week routine medical ultrasound for screening of congenital anomalies, but may also occur earlier, for example, when a commercial ultrasound is performed at the request of the parents.Another way DSD can be diagnosed before birth is when invasive prenatal genetic testing carried out for a different reason, for example, due to suspicion of other structural anomalies, reveals a discrepancy between the levitra cheap online genotypic sex and the phenotypic sex seen by ultrasound.

In certified laboratories, the possibility of a sample switch is extremely low but should be ruled out immediately. More often, the discrepancy will be due to sex-chromosome mosaicism or a true form of DSD.A situation now occurring levitra cheap online with increasing frequency is a discrepancy between the genotypic sex revealed by non-invasive prenatal testing (NIPT), which is now available to high-risk pregnant women in the Netherlands and to all pregnant women in Belgium, and later ultrasound findings. NIPT screens for CNVs in the fetus.

However, depending on legal restrictions and/or ethical considerations, levitra cheap online the X and Y chromosomes are not always included in NIPT analysis and reports. If the X and Y chromosomes are included, it is important to realise that the presence of a Y-chromosome does not necessarily imply male fetal development. At the time that NIPT is performed (usually 11–13 weeks), genital development cannot be reliably appreciated by ultrasound, so any discrepancy or atypical aspect of the genitalia will only be noticed later in pregnancy and should prompt further evaluation.Counselling and diagnosticsIf a DSD is suspected, first-line sonographers and obstetricians should refer levitra cheap online the couple to their colleague prenatal specialists working with or in a DSD team.

After confirming an atypical genital on ultrasound, the specialist team should offer the couple a referral for genetic counselling to discuss the possibility of performing invasive prenatal testing (usually an amniocentesis) to identify an underlying cause that fits the ultrasound findings.22 23 To enable the parents to make a well-informed decision, prenatal counselling should, in our opinion, include. Information on the ultrasound findings and the limitations of levitra cheap online this technique. The procedure(s) that can be followed, including the risks associated with an amniocentesis.

And the type of information genetic testing can and cannot provide levitra cheap online. Knowing which information has been provided and what words have been used by the prenatal specialist is very helpful for those involved in postnatal care.It is important that parents understand that the biological sex of a baby is determined by a complex interplay of chromosomes, genes and hormones, and thus that assessment of the presence or absence of a Y-chromosome alone is insufficient to assign the sex of their unborn child or, as in any unborn child, say anything about the child’s future gender identity.Expecting parents can be counselled by the clinical geneticist and the psychologist from the DSD team, although other DSD specialists can also be involved. The clinical geneticist should be experienced in prenatal counselling and well informed about the diagnostic possibilities given the limited time span in which test results need to be available to allow parents to make a well-informed decision about whether or levitra cheap online not to continue the pregnancy.

Termination of pregnancy can be considered, for instance, in a syndromic form of DSD with multiple malformations, but when the DSD occurs as an apparently isolated condition, expecting parents may also consider termination of pregnancy, which, although considered controversial by some, is legal in levitra cheap online Belgium and the Netherlands. The psychologist of the DSD team can support parents during and after pregnancy and help them cope with feelings of uncertainty and eventual considerations of a termination of pregnancy, as well as with practical issues, for example, how to inform others. The stress of not knowing exactly what the child’s genitalia will look like and uncertainty about the diagnosis, levitra cheap online treatment and prognosis cannot be avoided completely.

Parents are informed that if the postnatal phenotype is different from what was prenatally expected, the advice given about diagnostic testing can be adjusted accordingly, for example, if a hypospadias is milder than was expected based on prenatal ultrasound images. In our experience, parents appreciate having levitra cheap online already spoken to some members of the DSD team during pregnancy and having a contact person before birth.After expert prenatal counselling, a significant number of pregnant couples decline prenatal testing (personal experience IALG, MK, ABD, YvB, MC and HC-vdG). At birth, umbilical cord blood is a good source for (molecular) karyotyping and storage of DNA and can be obtained by the obstetrician, midwife or neonatologist.

The terminology used in communication with parents should be carefully chosen,22 23 and midwives and staff of neonatal and delivery units should be clearly instructed to use gender-neutral and non-stigmatising vocabulary (eg, ‘your baby’) as long as sex assignment is pending.An algorithm for diagnostic evaluation of a suspected DSD in the levitra cheap online prenatal situation is proposed in figure 1. When couples opt for invasive prenatal diagnosis, the genetic analysis usually involves an (SNP)-array. It was recently estimated that >30% of individuals who have a DSD have additional structural anomalies, with cardiac and neurological anomalies and fetal growth restriction being particularly common.27 28 If additional anomalies are seen, the geneticist can levitra cheap online consider specific gene defects that may underlie a known genetic syndrome or carry out NGS.

NGS-based techniques have also now made their appearance in prenatal diagnosis of congenital anomalies.29 30 Panels using these techniques can be specific for genes involved in DSD, or be larger panels covering multiple congenital anomalies, and are usually employed with trio-analysis to compare variants identified in the child with the parents’ genetics.29–31 Finding a genetic cause before delivery can help reduce parental stress in the neonatal period and speed up decisions regarding gender assignment. In such cases there is no tight time limit, and we propose completing the analysis well before the levitra cheap online expected delivery.Disorders/differences of sex development (DSD) in the prenatal setting.

NGS, next-generation sequencing.First contact by a professional less experienced in DSDWhereas most current guidelines start from the point when an individual has been referred to the DSD team,1 15 the Dutch-Flemish guideline dedicates a chapter to healthcare professionals less experienced in DSD as they are often the first to suspect or identify such a condition.

Apart from the paper of Indyk,7 little guidance is available for these professionals about how to act in such a situation. The chapter in the Dutch-Flemish guideline summarises the various clinical presentations that a DSD can have and provides information on how to communicate with parents and/or patients about the findings of the physical examination, the first-line investigations and the need for prompt referral to a specialised centre for further evaluation. Clinical examples are offered to illustrate some of these recurring situations.

The medical issues in DSD can be very challenging, and the social and psychological impact is high. For neonates with ambiguous genitalia, sex assignment is an urgent and crucial issue, and it is mandatory that parents are informed that it is possible to postpone registration of their child’s sex. In cases where sex assignment has already taken place, the message that the development of the gonads or genitalia is still atypical is complicated and distressing for patients and parents or carers.

A list of contact details for DSD centres and patient organisations in the Netherlands and Flanders is attached to the Dutch-Flemish guideline. Publishing such a list, either in guidelines or online, can help healthcare professionals find the nearest centres for consultations and provide patients and patient organisations with an overview of the centres where expertise is available.Timing and place of genetic testing using NGS-based gene panelsThe diagnostic workup that is proposed for 46,XX and 46,XY DSD is shown in figures 2 and 3, respectively. Even with the rapidly expanding molecular possibilities, a (family) history and a physical examination remain the essential first steps in the diagnostic process.

Biochemical and hormonal screening aim at investigating serum electrolytes, renal function and the hypothalamic-pituitary-gonadal and hypothalamic-pituitary-adrenal axes. Ultrasound screening of kidneys and internal genitalia, as well as establishing genotypic sex, should be accomplished within 48 hours and complete the baseline diagnostic work-up of a child born with ambiguous genitalia.1 16 32 3346,XX disorders/differences of sex development (DSD) in the postnatal setting.

Conventional karyotyping can be useful. NGS, next-generation sequencing.Very recently, a European position paper has been published focusing on the genetic workup of DSD.16 It highlights the limitations and drawbacks of NGS-based tests, which include the chance of missing subtle structural variants such as CNVs and mosaicism and the fact that NGS cannot detect methylation defects or other epigenetic changes.16 28 31 Targeted DNA analysis is preferred in cases where hormonal investigations suggest a block in steroidogenesis (eg, 11-β-hydroxylase deficiency, 21-hydroxylase deficiency), or in the context of a specific clinical constellation such as the often coincidental finding of Müllerian structures in a boy with normal external genitalia or cryptorchidism, that is, persistent Müllerian duct syndrome.33 34 Alternative tests should also be considered depending on the available information. Sometimes, a simple mouth swab for FISH analysis can detect mosaic XY/X in a male with hypospadias or asymmetric gonadal development or in a female with little or no Turner syndrome stigmata and a normal male molecular karyotyping profile or peripheral blood karyotype.

Such targeted testing avoids incidental findings and is cheaper and faster than analysis of a large NGS-based panel, although the cost difference is rapidly declining.However, due to the genetic and phenotypic heterogeneity of DSD conditions, the most cost-effective next steps in the majority of cases are whole exome sequencing followed by panel analysis of genes involved in genital development and function or trio-analysis of a large gene panel (such as a Mendeliome).16 35–38 Pretest genetic counselling involves discussing what kind of information will be reported to patients or parents and the chance of detecting VUS, and the small risk of incidental findings when analysing a DSD panel should be mentioned. Laboratories also differ in what class of variants they report.39 In our experience, the fear of incidental findings is a major reason why some parents refrain from genetic testing.Timing of the DSD gene panel analysis is also important. While some patients or parents prefer that all diagnostic procedures be performed as soon as possible, others need time to reflect on the complex information related to more extensive genetic testing and on its possible consequences.

If parents or patients do not consent to panel-based genetic testing, analysis of specific genes, such as WT1, should be considered when appropriate in view of the clinical consequences if a mutation is present (eg, clinical surveillance of renal function and screening for Wilms’ tumour in the case of WT1 mutations). Genes that are more frequently involved in DSD (eg, SRY, NR5A1) and that match the specific clinical and hormonal features in a given patient could also be considered for sequencing. Targeted gene analysis may also be preferred in centres located in countries that do not have the resources or technical requirements to perform NGS panel-based genetic testing.

Alternatively, participation by these centres in international collaborative networks may allow them to outsource the molecular genetic workup abroad.Gene panels differ between centres and are regularly updated based on scientific progress. A comparison of DSD gene panels used in recent studies can be found at https://www.nature.com/articles/s41574-018-0010-8%23Sec46.15 The panels currently used at the coauthors’ institutions can be found on their respective websites. Given the pace of change, it is important to regularly consider repeating analysis in patients with an unexplained DSD, for example, when they transition into adult care or when they move from one centre to another.

This also applies to patients in whom a clinical diagnosis has never been genetically confirmed. Confusion may arise when the diagnosis cannot be confirmed or when a mutation is identified in a different gene, for example, NR5A1 in someone with a clinical diagnosis of CAIS that has other consequences for relatives. Hence, new genetic counselling should always accompany new diagnostic endeavours.Class 3 variants and histopathological examinationsThe rapidly evolving diagnostic possibilities raise new questions.

What do laboratories report?. How should we deal with the frequent findings of mainly unique VUS or class 3 variants (ACMG recommendation) in the many different DSD-related genes in the diagnostic setting?. Reporting VUS can be a source of uncertainty for parents, but not reporting these variants precludes further investigations to determine their possible pathogenicity.

It can also be difficult to prove variant pathogenicity, both on gene-level and variant-level.39 Moreover, given the gonad-specific expression of some genes and the variable phenotypic spectrum and reduced penetrance, segregation analysis is not always informative. A class 3 variant that does not fit the clinical presentation may be unrelated to the observed phenotype, but it could also represent a newly emerging phenotype. This was recently demonstrated by the identification of the NR5A1 mutation, R92W, in individuals with 46,XX testicular and ovotesticular DSD.40 This gene had previously been associated with 46,XY DSD.

In diagnostic laboratories, there is usually no capacity or expertise to conduct large-scale functional studies to determine pathogenicity of these unique class 3 VUS in the different genes involved in DSD. Functional validation of variants identified in novel genes may be more attractive in a research context. However, for individual families with VUS in well-established DSD genes such as AR or HSD17B3, functional analysis may provide a confirmed diagnosis that implies for relatives the option of undergoing their own DNA analysis and estimating the genetic risk of their own future offspring.

This makes genetic follow-up important in these cases and demonstrates the usefulness of international databases and networks and the centralisation of functional studies of genetic variants in order to reduce costs and maximise expertise.The same is true for histopathological description, germ-cell tumour risk assessment in specific forms of DSD and classification of gonadal samples. Germ-cell tumour risk is related to the type of DSD (among other factors), but it is impossible to make risk estimates in individual cases.41–44 Gonadectomy may be indicated in cases with high-risk dysgenetic abdominal gonads that cannot be brought into a stable superficial (ie, inguinal, labioscrotal) position that allows clinical or radiological surveillance, or to avoid virilisation due to 5-alpha reductase deficiency in a 46,XY girl with a stable female gender identity.45 Pathological examination of DSD gonads requires specific expertise. For example, the differentiation between benign germ cell abnormalities, such as delayed maturation and (pre)malignant development of germ cells, is crucial for clinical management but can be very troublesome.46 Centralised pathological examination of gonadal biopsy and gonadectomy samples in one centre, or a restricted number of centres, on a national scale can help to overcome the problem of non-uniform classification and has proven feasible in the Netherlands and Belgium.

We therefore believe that uniform assessment and classification of gonadal differentiation patterns should also be addressed in guidelines on DSD management.International databases of gonadal tissues are crucial for learning more about the risk of malignancy in different forms of DSD, but they are only reliable if uniform criteria for histological classification are strictly applied.46 These criteria could be incorporated in many existing networks such as the I-DSD consortium, the Disorders of Sex Development Translational Research Network, the European Reference Network on Urogenital Diseases (eUROGEN), the EndoERN and COST actions.15–17 47Communication at the transition from paediatric to adult carePaediatric and adult teams need to collaborate closely to facilitate a well-organised transition from paediatric to adult specialist care.15 48–50 Both teams need to exchange information optimally and should consider transition as a longitudinal process rather than a fixed moment in time. Age-appropriate information is key at all ages, and an overview of topics to be discussed at each stage is described by Cools et al.15 Table 1 shows an example of how transition can be organised.View this table:Table 1 Example of transition table as used in the DSD clinic of the Erasmus Medical CenterPsychological support and the continued provision of information remains important for individuals with a DSD at all ages.15 22 In addition to the information given by the DSD team members, families and patients can benefit from resources such as support groups and information available on the internet.47 Information available online should be checked for accuracy and completeness when referring patients and parents to internet sites.Recommendations for future actionsMost guidelines and articles on the diagnosis and management of DSD are aimed at specialists and are only published in specialist journals or on websites for endocrinologists, urologists or geneticists. Yet there is a need for guidelines directed towards first-line and second-line healthcare workers that summarise the recommendations about the first crucial steps in the management of DSD.

These should be published in widely available general medical journals and online, along with a national list of DSD centres. Furthermore, DSD (expert) centres should provide continuous education to all those who may be involved in the identification of individuals with a DSD in order to enable these healthcare professionals to recognise atypical genitalia, to promptly refer individuals who have a DSD and to inform the patient and parents about this and subsequent diagnostic procedures.As DSD continues to be a rare condition, it will take time to evaluate the effects of having such a guideline on the preparedness of first-line and second-line healthcare workers to recognise DSD conditions. One way to evaluate this might be the development and use of questionnaires asking patients, carers and families and referring physicians how satisfied they were with the initial medical consultation and referral and what could be improved.

A helpful addition to existing international databases that collect information on genetic variations would be a list of centres that offer suitable functional studies for certain genes, ideally covering the most frequently mutated genes (at minimum).Patient organisations can also play an important role in informing patients about newly available diagnostic or therapeutic strategies and options, and their influence and specific role has now been recognised and discussed in several publications.17 47 However, it should be kept in mind that these organisations do not represent all patients, as a substantial number of patients and parents are not member of such an organisation.Professionals have to provide optimal medical care based on well-established evidence, or at least on broad consensus. Yet not everything can be regulated by recommendations and guidelines. Options, ideas and wishes should be openly discussed between professionals, patients and families within their confidential relationship.

This will enable highly individualised holistic care tailored to the patient’s needs and expectations. Once they are well-informed of all available options, parents and/or patients can choose what they consider the optimal care for their children or themselves.15 16ConclusionThe Dutch-Flemish guideline uniquely addresses some topics that are under-represented in the literature, thus adding some key aspects to those addressed in recent consensus papers and guidelines.15–17 33 47As more children with a DSD are now being identified prenatally, and the literature on prenatal diagnosis of DSD remains scarce,20 21 we propose a prenatal diagnostic algorithm and emphasise the importance of having a prenatal specialist involved in or collaborating with DSD (expert) centres.We also stress that good communication between all involved parties is essential. Professionals should be well informed about protocols and communication.

Collaboration between centres is necessary to optimise aspects of care such as uniform interpretation of gonadal pathology and functional testing of class 3 variants found by genetic testing. Guidelines can provide a framework within which individualised patient care should be discussed with all stakeholders.AcknowledgmentsThe authors would like to thank the colleagues of the DSD teams for their input in and critical reading of the Dutch-Flemish guideline.

Three of the authors of this publication are members of the European Reference Network for rare endocrine diseases—Project ID 739543.IntroductionEndometrial cancer is the most common gynaecological malignancy in the developed world.1 Its incidence has risen over the last two decades as a consequence of the ageing population, fewer hysterectomies for benign disease and the obesity epidemic. In the USA, it is estimated that women have a 1 in 35 lifetime risk of endometrial cancer, and in contrast to cancers of most other sites, cancer-specific mortality has risen by approximately 2% every year since 2008 related to the rapidly rising incidence.2Endometrial cancer has traditionally been classified into type I and type II based on morphology.3 The more common subtype, type I, is mostly comprised of endometrioid tumours and is oestrogen-driven, arises from a hyperplastic endometrium, presents at an early stage and has an excellent 5 year survival rate.4 By contrast, type II includes non-endometrioid tumours, specifically serous, carcinosarcoma and clear cell subtypes, which are biologically aggressive tumours with a poor prognosis that are often diagnosed at an advanced stage.5 Recent efforts have focused on a molecular classification system for more accurate categorisation low price levitra of endometrial tumours into four groups with distinct prognostic profiles.6 7The majority of endometrial cancers arise through the interplay of familial, genetic and lifestyle factors.

Two inherited cancer predisposition syndromes, Lynch syndrome and the much rarer Cowden syndrome, substantially increase the lifetime risk of endometrial cancer, but these only account for around 3–5% of cases.8–10 Having first or second degree relative(s) with endometrial or colorectal cancer increases endometrial cancer risk, although a large European twin study failed to demonstrate a strong heritable link.11 The authors failed to show that there was greater concordance in monozygotic than dizygotic twins, but the study was based on relatively small numbers of endometrial cancers. Lu and colleagues reported an association between common single nucleotide polymorphisms (SNPs) and endometrial cancer risk, revealing the potential role of SNPs in explaining part of the risk in both the familial and general populations.12 Thus far, many SNPs have been reported to modify susceptibility to endometrial cancer. However, much of this work predated genome wide association studies and is of variable quality.

Understanding genetic predisposition to endometrial cancer could facilitate personalised risk assessment with a view to targeted prevention and screening interventions.13 This emerged as the most important unanswered research question in endometrial cancer according to patients, carers and healthcare professionals in our recently completed James Lind Womb Cancer Alliance Priority Setting Partnership.14 It would be particularly useful for non-endometrioid endometrial cancers, for which advancing age is so far the only predictor.15We therefore conducted a comprehensive systematic review of the literature to provide an overview of the relationship between SNPs and endometrial cancer risk. We compiled a list of the most robust endometrial cancer-associated SNPs. We assessed the applicability of this panel of SNPs with a theoretical polygenic risk score (PRS) calculation.

We also critically appraised the meta-analyses investigating the most frequently reported SNPs in MDM2. Finally, we described all SNPs reported within genes and pathways that are likely involved in endometrial carcinogenesis and metastasis.MethodsOur systematic review follows the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) collaboration 2009 recommendations. The registered protocol is available through PROSPERO (CRD42018091907).16Search strategyWe searched Embase, MEDLINE and Cumulative Index to Nursing and Allied Health Literature (CINAHL) databases via the Healthcare Databases Advanced Search (HDAS) platform, from 2007 to 2018, to identify studies reporting associations between polymorphisms and endometrial cancer risk.

Key words including MeSH (Medical Subject Heading) terms and free-text words were searched in both titles and abstracts. The following terms were used. €œendomet*”,“uter*”, “womb”, “cancer(s)”, “neoplasm(s)”, “endometrium tumour”, “carcinoma”, “adenosarcoma”, “clear cell carcinoma”, “carcinosarcoma”, “SNP”, “single nucleotide polymorphism”, “GWAS”, and “genome-wide association study/ies”.

No other restrictions were applied. The search was repeated with time restrictions between 2018 and June 2019 to capture any recent publications.Eligibility criteriaStudies were selected for full-text evaluation if they were primary articles investigating a relationship between endometrial cancer and SNPs. Study outcome was either the increased or decreased risk of endometrial cancer relative to controls reported as an odds ratio (OR) with corresponding 95% confidence intervals (95% CIs).Study selectionThree independent reviewers screened all articles uploaded to a screening spreadsheet developed by Helena VonVille.17 Disagreements were resolved by discussion.

Chronbach’s α score was calculated between reviewers and indicated high consistency at 0.92. Case–control, prospective and retrospective studies, genome-wide association studies (GWAS), and both discovery and validation studies were selected for full-text evaluation. Non-English articles, editorials, conference abstracts and proceedings, letters and correspondence, case reports and review articles were excluded.Candidate-gene studies with at least 100 women and GWAS with at least 1000 women in the case arm were selected to ensure reliability of the results, as explained by Spencer et al.18 To construct a panel of up to 30 SNPs with the strongest evidence of association, those with the strongest p values were selected.

For the purpose of an SNP panel, articles utilising broad European or multi-ethnic cohorts were selected. Where overlapping populations were identified, the most comprehensive study was included.Data extraction and synthesisFor each study, the following data were extracted. SNP ID, nearby gene(s)/chromosome location, OR (95% CI), p value, minor or effect allele frequency (MAF/EAF), EA (effect allele) and OA (other allele), adjustment, ethnicity and ancestry, number of cases and controls, endometrial cancer type, and study type including discovery or validation study and meta-analysis.

For risk estimates, a preference towards most adjusted results was applied. For candidate-gene studies, a standard p value of<0.05 was applied and for GWAS a p value of <5×10-8, indicating genome-wide significance, was accepted as statistically significant. However, due to the limited number of SNPs with p values reaching genome-wide significance, this threshold was then lowered to <1×10-5, allowing for marginally significant SNPs to be included.

As shown by Mavaddat et al, for breast cancer, SNPs that fall below genome-wide significance may still be useful for generating a PRS and improving the models.19We estimated the potential value of a PRS based on the most significant SNPs by comparing the predicted risk for a woman with a risk score in the top 1% of the distribution to the mean predicted risk. Per-allele ORs and MAFs were taken from the publications and standard errors (SEs) for the lnORs were derived from published 95% CIs. The PRS was assumed to have a Normal distribution, with mean 2∑βipI and SE, σ, equal to √2∑βi2pI(1−pi), according to the binomial distribution, where the summation is over all SNPs in the risk score.

Hence the relative risk (RR) comparing the top 1% of the distribution to the mean is given by exp(Z0.01σ), where Z is the inverse of the standard normal cumulative distribution.ResultsThe flow chart of study selection is illustrated in figure 1. In total, 453 text articles were evaluated and, of those, 149 articles met our inclusion criteria. One study was excluded from table 1, for having an Asian-only population, as this would make it harder to compare with the rest of the results which were all either multi-ethnic or Caucasian cohorts, as stated in our inclusion criteria for the SNP panel.20 Any SNPs without 95% CIs were also excluded from any downstream analysis.

Additionally, SNPs in linkage disequilibrium (r2 >0.2) with each other were examined, and of those in linkage disequilibrium, the SNP with strongest association was reported. Per allele ORs were used unless stated otherwise.View this table:Table 1 List of top SNPs most likely to contribute to endometrial cancer risk identified through systematic review of recent literature21–25Study selection flow diagram. *Reasons.

Doi:10.1371/journal.pmed1000097.Top SNPs associated with endometrial cancer riskFollowing careful interpretation of the data, 24 independent SNPs with the lowest p values that showed the strongest association with endometrial cancer were obtained (table 1).21–25 These SNPs are located in or around genes coding for transcription factors, cell growth and apoptosis regulators, and enzymes involved in the steroidogenesis pathway. All the SNPs presented here were reported on the basis of a GWAS or in one case, an exome-wide association study, and hence no SNPs from candidate-gene studies made it to the list. This is partly due to the nature of larger GWAS providing more comprehensive and powered results as opposed to candidate gene studies.

Additionally, a vast majority of SNPs reported by candidate-gene studies were later refuted by large-scale GWAS such as in the case of TERT and MDM2 variants.26 27 The exception to this is the CYP19 gene, where candidate-gene studies reported an association between variants in this gene with endometrial cancer in both Asian and broad European populations, and this association was more recently confirmed by large-scale GWAS.21 28–30 Moreover, a recent article authored by O’Mara and colleagues reviewed the GWAS that identified most of the currently known SNPs associated with endometrial cancer.31Most of the studies represented in table 1 are GWAS and the majority of these involved broad European populations. Those having a multi-ethnic cohort also consisted primarily of broad European populations. Only four of the variants in table 1 are located in coding regions of a gene, or in regulatory flanking regions around the gene.

Thus, most of these variants would not be expected to cause any functional effects on the gene or the resulting protein. An eQTL search using GTEx Portal showed that some of the SNPs are significantly associated (p<0.05) with modified transcription levels of the respective genes in various tissues such as prostate (rs11263761), thyroid (rs9668337), pituitary (rs2747716), breast mammary (rs882380) and testicular (rs2498794) tissue, as summarised in table 2.View this table:Table 2 List of eQTL hits for the selected panel of SNPsThe only variant for which there was an indication of a specific association with non-endometrioid endometrial cancer was rs148261157 near the BCL11A gene. The A allele of this SNP had a moderately higher association in the non-endometrioid arm (OR 1.64, 95% CI 1.32 to 2.04.

P=9.6×10-6) compared with the endometrioid arm (OR 1.25, 95% CI 1.14 to 1.38. P=4.7×10-6).21Oestrogen receptors α and β encoded by ESR1 and ESR2, respectively, have been extensively studied due to the assumed role of oestrogens in the development of endometrial cancer. O’Mara et al reported a lead SNP (rs79575945) in the ESR1 region that was associated with endometrial cancer (p=1.86×10-5).24 However, this SNP did not reach genome-wide significance in a more recent larger GWAS.21 No statistically significant associations have been reported between endometrial cancer and SNPs in the ESR2 gene region.AKT is an oncogene linked to endometrial carcinogenesis.

It is involved in the PI3K/AKT/mTOR pro-proliferative signalling pathway to inactivate apoptosis and allow cell survival. The A allele of rs2494737 and G allele of rs2498796 were reported to be associated with increased and decreased risk of endometrial cancer in 2016, respectively.22 30 However, this association was not replicated in a larger GWAS in 2018.21 Nevertheless, given the previous strong indications, and biological basis that could explain endometrial carcinogenesis, we decided to include an AKT1 variant (rs2498794) in our results.PTEN is a multi-functional tumour suppressor gene that regulates the AKT/PKB signalling pathway and is commonly mutated in many cancers including endometrial cancer.32 Loss-of-function germline mutations in PTEN are responsible for Cowden syndrome, which exerts a lifetime risk of endometrial cancer of up to 28%.9 Lacey and colleagues studied SNPs in the PTEN gene region. However, none showed significant differences in frequency between 447 endometrial cancer cases and 439 controls of European ancestry.33KRAS mutations are known to be present in endometrial cancer.

These can be activated by high levels of KLF5 (transcriptional activator). Three SNPs have been identified in or around KLF5 that are associated with endometrial cancer. The G allele of rs11841589 (OR 1.15, 95% CI 1.11 to 1.21.

P=4.83×10-11), the A allele of rs9600103 (OR 1.23, 95% CI 1.16 to 1.30. P=3.76×10-12) and C allele of rs7981863 (OR 1.16, 95% CI 1.12 to 1.20. P=2.70×10-17) have all been found to be associated with an increased likelihood of endometrial cancer in large European cohorts.21 30 34 It is worth noting that these SNPs are not independent, and hence they quite possibly tag the same causal variant.The MYC family of proto-oncogenes encode transcription factors that regulate cell proliferation, which can contribute to cancer development if dysregulated.

The recent GWAS by O’Mara et al reported three SNPs within the MYC region that reached genome-wide significance with conditional p values reaching at least 5×10–8.35To test the utility of these SNPs as predictive markers, we devised a theoretical PRS calculation using the log ORs and EAFs per SNP from the published data. The results were very encouraging with an RR of 3.16 for the top 1% versus the mean, using all the top SNPs presented in table 1 and 2.09 when using only the SNPs that reached genome-wide significance (including AKT1).Controversy surrounding MDM2 variant SNP309MDM2 negatively regulates tumour suppressor gene TP53, and as such, has been extensively studied in relation to its potential role in predisposition to endometrial cancer. Our search identified six original studies of the association between MDM2 SNP rs2279744 (also referred to as SNP309) and endometrial cancer, all of which found a statistically significant increased risk per copy of the G allele.

Two more original studies were identified through our full-text evaluation. However, these were not included here as they did not meet our inclusion criteria—one due to small sample size, the other due to studying rs2279744 status dependent on another SNP.36 37 Even so, the two studies were described in multiple meta-analyses that are listed in table 3. Different permutations of these eight original studies appear in at least eight published meta-analyses.

However, even the largest meta-analysis contained <2000 cases (table 3)38View this table:Table 3 Characteristics of studies that examined MDM2 SNP rs2279744In comparison, a GWAS including nearly 13 000 cases found no evidence of an association with OR and corresponding 95% CI of 1.00 (0.97 to 1.03) and a p value of 0.93 (personal communication).21 Nevertheless, we cannot completely rule out a role for MDM2 variants in endometrial cancer predisposition as the candidate-gene studies reported larger effects in Asians, whereas the GWAS primarily contained participants of European ancestry. There is also some suggestion that the SNP309 variant is in linkage disequilibrium with another variant, SNP285, which confers an opposite effect.It is worth noting that the SNP285C/SNP309G haplotype frequency was observed in up to 8% of Europeans, thus requiring correction for the confounding effect of SNP285C in European studies.39 However, aside from one study conducted by Knappskog et al, no other study including the meta-analyses corrected for the confounding effect of SNP285.40 Among the studies presented in table 3, Knappskog et al (2012) reported that after correcting for SNP285, the OR for association of this haplotype with endometrial cancer was much lower, though still significant. Unfortunately, the meta-analyses which synthesised Knappskog et al (2012), as part of their analysis, did not correct for SNP285C in the European-based studies they included.38 41 42 It is also concerning that two meta-analyses using the same primary articles failed to report the same result, in two instances.38 42–44DiscussionThis article represents the most comprehensive systematic review to date, regarding critical appraisal of the available evidence of common low-penetrance variants implicated in predisposition to endometrial cancer.

We have identified the most robust SNPs in the context of endometrial cancer risk. Of those, only 19 were significant at genome-wide level and a further five were considered marginally significant. The largest GWAS conducted in this field was the discovery- and meta-GWAS by O’Mara et al, which utilised 12 096 cases and 108 979 controls.21 Despite the inclusion of all published GWAS and around 5000 newly genotyped cases, the total number did not reach anywhere near what is currently available for other common cancers such as breast cancer.

For instance, BCAC (Breast Cancer Association Consortium) stands at well over 200 000 individuals with more than half being cases, and resulted in identification of ~170 SNPs in relation to breast cancer.19 45 A total of 313 SNPs including imputations were then used to derive a PRS for breast cancer.19 Therefore, further efforts should be directed to recruit more patients, with deep phenotypic clinical data to allow for relevant adjustments and subgroup analyses to be conducted for better precision.A recent pre-print study by Zhang and colleagues examined the polygenicity and potential for SNP-based risk prediction for 14 common cancers, including endometrial cancer, using available summary-level data from European-ancestry datasets.46 They estimated that there are just over 1000 independent endometrial cancer susceptibility SNPs, and that a PRS comprising all such SNPs would have an area under the receiver-operator curve of 0.64, similar to that predicted for ovarian cancer, but lower than that for the other cancers in the study. The modelling in the paper suggests that an endometrial cancer GWAS double the size of the current largest study would be able to identify susceptibility SNPs together explaining 40% of the genetic variance, but that in order to explain 75% of the genetic variance it would be necessary to have a GWAS comprising close to 150 000 cases and controls, far in excess of what is currently feasible.We found that the literature consists mainly of candidate-gene studies with small sample sizes, meta-analyses reporting conflicting results despite using the same set of primary articles, and multiple reports of significant SNPs that have not been validated by any larger GWAS. The candidate-gene studies were indeed the most useful and cheaper technique available until the mid to late 2000s.

However, a lack of reproducibility (particularly due to population stratification and reporting bias), uncertainty of reported associations, and considerably high false discovery rates make these studies much less appropriate in the post-GWAS era. Unlike the candidate-gene approach, GWAS do not require prior knowledge, selection of genes or SNPs, and provide vast amounts of data. Furthermore, both the genotyping process and data analysis phases have become cheaper, the latter particularly due to faster and open-access pre-phasing and imputation tools being made available.It is clear from table 1 that some SNPs were reported with wide 95% CI, which can be directly attributed to small sample sizes particularly when restricting the cases to non-endometrioid histology only, low EAF or poor imputation quality.

Thus, these should be interpreted with caution. Additionally, most of the SNPs reported by candidate-gene studies were not detected by the largest GWAS to date conducted by O’Mara et al.21 However, this does not necessarily mean that the possibility of those SNPs being relevant should be completely dismissed. Moreover, meta-analyses were attempted for other variants.

However, these showed no statistically significant association and many presented with high heterogeneity between the respective studies (data not shown). Furthermore, as many studies utilised the same set of cases and/or controls, conducting a meta-analysis was not possible for a good number of SNPs. It is therefore unequivocal that the literature is crowded with numerous small candidate-gene studies and conflicting data.

This makes it particularly hard to detect novel SNPs and conduct meaningful meta-analyses.We found convincing evidence for 19 variants that indicated the strongest association with endometrial cancer, as shown in table 1. The associations between endometrial cancer and variants in or around HNF1B, CYP19A1, SOX4, MYC, KLF and EIF2AK found in earlier GWAS were then replicated in the latest and largest GWAS. These SNPs showed promising potential in a theoretical PRS we devised based on published data.

Using all 24 or genome-wide significant SNPs only, women with a PRS in the top 1% of the distribution would be predicted to have a risk of endometrial cancer 3.16 and 2.09 times higher than the mean risk, respectively.However, the importance of these variants and relevance of the proximate genes in a functional or biological context is challenging to evaluate. Long distance promoter regulation by enhancers may disguise the genuine target gene. In addition, enhancers often do not loop to the nearest gene, further complicating the relevance of nearby gene(s) to a GWAS hit.

In order to elucidate biologically relevant candidate target genes in endometrial cancer, O’Mara et al looked into promoter-associated chromatin looping using a modern HiChIP approach.47 The authors utilised normal and tumoural endometrial cell lines for this analysis which showed significant enrichment for endometrial cancer heritability, with 103 candidate target genes identified across the 13 risk loci identified by the largest ECAC GWAS. Notable genes identified here were CDKN2A and WT1, and their antisense counterparts. The former was reported to be nearby of rs1679014 and the latter of rs10835920, as shown in table 1.

Moreover, of the 36 candidate target genes, 17 were found to be downregulated while 19 were upregulated in endometrial tumours.The authors also investigated overlap between the 13 endometrial cancer risk loci and top eQTL variants for each target gene.47 In whole blood, of the two particular lead SNPs, rs8822380 at 17q21.32 was a top eQTL for SNX11 and HOXB2, whereas rs937213 at 15q15.1 was a top eQTL for SRP14. In endometrial tumour, rs7579014 at 2p16.1 was found to be a top eQTL for BCL11A. This is particularly interesting because BCL11A was the only nearby/candidate gene that had a GWAS association reported in both endometrioid and non-endometrioid subtypes.

The study looked at protein–protein interactions between endometrial cancer drivers and candidate target gene products. Significant interactions were observed with TP53 (most significant), AKT, PTEN, ESR1 and KRAS, among others. Finally, when 103 target candidate genes and 387 proteins were combined together, 462 pathways were found to be significantly enriched.

Many of these are related to gene regulation, cancer, obesity, insulinaemia and oestrogen exposure. This study clearly showed a potential biological relevance for some of the SNPs reported by ECAC GWAS in 2018.Most of the larger included studies used cohorts primarily composed of women of broad European descent. Hence, there are negligible data available for other ethnicities, particularly African women.

This is compounded by the lack of reference genotype data available for comparative analysis, making it harder for research to be conducted in ethnicities other than Europeans. This poses a problem for developing risk prediction models that are equally valuable and predictive across populations. Thus, our results also are of limited applicability to non-European populations.Furthermore, considering that non-endometrioid cases comprise a small proportion (~20%) of all endometrial cancer cases, much larger cohort sizes are needed to detect any genuine signals for non-endometrioid tumours.

Most of the evaluated studies looked at either overall/mixed endometrial cancer subtypes or endometrioid histology, and those that looked at variant associations with non-endometrioid histology were unlikely to have enough power to detect any signal with statistical significance. This is particularly concerning because non-endometrioid subtypes are biologically aggressive tumours with a much poorer prognosis that contribute disproportionately to mortality from endometrial cancer. It is particularly important that attempts to improve early detection and prevention of endometrial cancer focus primarily on improving outcomes from these subtypes.

It is also worth noting that, despite the current shift towards a molecular classification of endometrial cancer, most studies used the overarching classical Bokhman’s classification system, type I versus type II, or no histological classification system at all. Therefore, it is important to create and follow a standardised and comprehensive classification system for reporting tumour subtypes for future studies.This study compiled and presented available information for an extensively studied, yet unproven in large datasets, SNP309 variant in MDM2. Currently, there is no convincing evidence for an association between this variant and endometrial cancer risk.

Additionally, of all the studies, only one accounted for the opposing effect of a nearby variant SNP285 in their analyses. Thus, we conclude that until confirmed by a sufficiently large GWAS, this variant should not be considered significant in influencing the risk of endometrial cancer and therefore not included in a PRS. This is also true for the majority of the SNPs reported in candidate-gene studies, as the numbers fall far short of being able to detect genuine signals.This systematic review presents the most up-to-date evidence for endometrial cancer susceptibility variants, emphasising the need for further large-scale studies to identify more variants of importance, and validation of these associations.

Until data from larger and more diverse cohorts are available, the top 24 SNPs presented here are the most robust common genetic variants that affect endometrial cancer risk. The multiplicative effects of these SNPs could be used in a PRS to allow personalised risk prediction models to be developed for targeted screening and prevention interventions for women at greatest risk of endometrial cancer..

Elon Musk on Friday unveiled a coin-sized prototype of a brain implant developed by his startup Neuralink to enable people who are paralyzed to operate buy levitra online in usa smartphones and robotic limbs with their thoughts — and said the company had worked to “dramatically simplify” the device since presenting an earlier version last summer.In an event live-streamed on YouTube to more than 150,000 levitra 10mg dosage viewers at one point, the company staged a demonstration in which it trotted out a pig named Gertrude that was said to have had the company’s device implanted in its head two months ago. The live stream showed what Musk claimed to be Gertrude’s real-time brain activity as it sniffed around a pen. At no point, though, did he provide evidence that the signals — rendered in beeps and bright blue wave patterns on screen — were, in fact, emanating from the pig’s brain.A pig presented at a Neuralink demonstration was said to have levitra 10mg dosage one of the company’s brain implants in its head. YouTube screenshot“This is obviously sounding increasingly like a Black Mirror episode,” Musk said at one point during the event as he responded affirmatively to a question about whether the company’s implant could eventually be used to save and replay memories.

€œThe future’s going to be weird.”advertisement Musk said that in July Neuralink received a breakthrough device designation from the Food and Drug Administration — a regulatory pathway that could allow the company to soon start a levitra 10mg dosage clinical trial in people with paraplegia and tetraplegia. The big reveal came after four former Neuralink employees told STAT that the company’s leaders have long fostered an internal culture characterized by rushed timelines and the “move fast and break things” ethos of a tech company — a pace sometimes at odds with the slow and incremental pace that’s typical of medical device development. Advertisement Friday’s event began, 40 minutes late, with a glossy video about the company’s work — and then panned to levitra 10mg dosage Musk, standing in front of a blue curtain beside a gleaming new version of the company’s surgical “sewing machine” robot that could easily have been mistaken for a giant Apple device. Musk described the event as a “product demo” and said its primary purpose was to recruit potential new employees.

It was unclear whether the demonstration was taking place at the company’s levitra 10mg dosage Fremont, Calif., headquarters or elsewhere. Musk proceeded to reveal the new version of Neuralink’s brain implant, which he said was designed to fit snugly into the top of the skull. Neuralink’s technological design has changed significantly since its last big levitra 10mg dosage update in July 2019. At that time, the company’s brain implant system involved a credit-card sized device designed to be positioned behind the back of a person’s ear, with several wires stretching to the top of the skull.

After demonstrating the pig’s brain activity at Friday’s event, Musk showed video footage of a pig walking on a treadmill and said Neuralink’s device could be used to “predict levitra 10mg dosage the position of limbs with high accuracy.” That capability would be critical to allowing someone using the device to do something like controlling a prosthetic limb, for example.Neuralink for months has signaled that it initially plans to develop its device for people who are paralyzed. It said at its July 2019 event that it wanted to start human testing by the end of 2020. Receiving the breakthrough device designation from the FDA — designed to speed up the lengthy regulatory process — is a step forward, levitra 10mg dosage but it by no means guarantees that a device will receive a green light, either in a short or longer-term time frame. After Musk’s presentation, a handful of the company’s employees — all wearing masks, but seated only inches apart — joined him to take questions submitted on Twitter or from the small audience in the room.In typical fashion for a man who in 2018 sent a Tesla Roadster into space, Musk didn’t hesitate to use the event to cross-promote his electric car company.

Asked whether the Neuralink chip levitra 10mg dosage would allow people to summon their Tesla telepathically, Musk responded. €œDefinitely — of course.”Matthew MacDougall, the company’s head neurosurgeon, appearing in scrubs, said the company had so far only implanted its technology into the brain’s cortical surface, the coaster-width layer enveloping the brain, but added that it hoped to go deeper in the future. Still, Musk levitra 10mg dosage said. €œYou could solve blindness, you could solve paralysis, you could solve hearing — you can solve a lot just by interfacing with the cortex.”Musk and MacDougall said they hoped to eventually implant Neuralink’s devices — which they referred to on stage simply as “links” — in the deeper structures of the brain, such as in the hypothalamus, which is believed to play a critical role in mental illnesses including depression, anxiety, and PTSD.There were no updates at the event of Neuralink’s research in monkeys, which the company has been conducting in partnership with the University of California, Davis since 2017.

At last July’s event, Musk said — without providing evidence — that a monkey had controlled a computer with its brain.At that same July 2019 event, Neuralink released levitra 10mg dosage a preprint paper — published a few months later — that claimed to show that a series of Neuralink electrodes implanted in the brains of rats could record neural signals. Critically, the work did not show where in the brain the implanted electrodes were recording from, for how long they were recording, or whether the recordings could be linked to any of the rats’ bodily movements.In touting Friday’s event — and Neuralink’s technological capabilities — on Twitter in recent weeks, Musk spoke of “AI symbiosis while u wait” and referenced the “matrix in the matrix” — a science-fiction reference about revealing the true nature of reality. The progress the company reported on Friday fell far short of levitra 10mg dosage that. Neuralink’s prototype is ambitious, but it has yet to show evidence that it can match up to the brain-machine interfaces developed by academic labs and other companies.

Other groups have shown that they can listen in on neural activity and allow primates and people to control a computer cursor with their brain — so-called “read-out” technology — and have also shown that they can use electrical stimulation to input information, such as a command or the heat levitra 10mg dosage of a hot cup of coffee, using “write-in” technology. Neuralink said on Friday that its technology would have both read-out and write-in capabilities.Musk acknowledged that Neuralink still has a long way to go. In closing the event after more than 70 minutes, levitra 10mg dosage Musk said. €œThere’s a tremendous amount of work to be done to go from here to a device that is widely available and affordable and reliable.”Following the news this week of what appears to have been the first confirmed case of a Covid-19 reinfection, other researchers have been coming forward with their own reports.

One in levitra 10mg dosage Belgium, another in the Netherlands. And now, one in Nevada.What caught experts’ attention about the case of the 25-year-old Reno man was not that he appears to have contracted SARS-CoV-2 (the name of the virus that causes Covid-19) a second time. Rather, it’s that his second bout was more serious than his first.Immunologists had expected that if the immune response generated after an initial infection could not prevent a second case, then it should at least stave off more severe illness levitra 10mg dosage. That’s what occurred with the first known reinfection case, in a 33-year-old Hong Kong man.advertisement Still, despite what happened to the man in Nevada, researchers are stressing this is not a sky-is-falling situation or one that should result in firm conclusions.

They always presumed people would become vulnerable to Covid-19 again some time levitra 10mg dosage after recovering from an initial case, based on how our immune systems respond to other respiratory viruses, including other coronaviruses. It’s possible that these early cases of reinfection are outliers and have features that won’t apply to the tens of millions of other people who have already shaken off Covid-19.“There are millions and millions of cases,” said Michael Mina, an epidemiologist at Harvard’s T.H. Chan School levitra 10mg dosage of Public Health. The real question that should get the most focus, Mina said, is, “What happens to most people?.

€advertisement But with more reinfection reports likely to make it into the scientific literature soon, and from there into the mainstream press, here are levitra 10mg dosage some things to look for in assessing them.What’s the deal with the Nevada case?. The Reno resident in question first tested positive for SARS-CoV-2 in April after coming down with a sore throat, cough, and headache, as well as nausea and diarrhea. He got levitra 10mg dosage better over time and later tested negative twice. But then, some 48 days later, the man started experiencing headaches, cough, and other symptoms again.

Eventually, he became so sick that he had to be hospitalized and was found to have pneumonia.Researchers sequenced virus samples from both of his infections and found they were different, providing evidence that this was a new infection distinct from the first. What happens when we get Covid-19 in the levitra 10mg dosage first case?. Researchers are finding that, generally, people who get Covid-19 develop a healthy immune response replete with both antibodies (molecules that can block pathogens from infecting cells) and T cells (which help wipe out the virus). This is what happens after other viral infections.In addition to fending off the virus the first time, that immune response also creates memories of levitra 10mg dosage the virus, should it try to invade a second time.

It’s thought, then, that people who recover from Covid-19 will typically be protected from another case for some amount of time. With other coronaviruses, protection is thought to last for perhaps a little less than a year to about three years.But researchers can’t tell levitra 10mg dosage how long immunity will last with a new pathogen (like SARS-CoV-2) until people start getting reinfected. They also don’t know exactly what mechanisms provide protection against Covid-19, nor do they know what levels of antibodies or T cells are required to signal that someone is protected through a blood test. (These are called levitra 10mg dosage the “correlates of protection.”) Why do experts expect second cases to be milder?.

With other viruses, protective immunity doesn’t just vanish one day. Instead, it levitra 10mg dosage wanes over time. Researchers have then hypothesized that with SARS-CoV-2, perhaps our immune systems might not always be able to prevent it from getting a toehold in our cells — to halt infection entirely — but that it could still put up enough of a fight to guard us from getting really sick. Again, this is what happens with other respiratory pathogens.And it’s why some researchers actually looked at levitra 10mg dosage the Hong Kong case with relief.

The man had mild to moderate Covid-19 symptoms during the first case, but was asymptomatic the second time. It was levitra 10mg dosage a demonstration, experts said, of what you would want your immune system to do. (The case was only detected because the man’s sample was taken at the airport when he arrived back in Hong Kong after traveling in Europe.)“The fact that somebody may get reinfected is not surprising,” Malik Peiris, a virologist at the University of Hong Kong, told STAT earlier this week about the first reinfection. €œBut the reinfection didn’t cause disease, so that’s the levitra 10mg dosage first point.”The Nevada case, then, provides a counterexample to that.

What kind of immune response did the person who was reinfected generate initially?. Earlier, we levitra 10mg dosage described the robust immune response that most people who have Covid-19 seem to mount. But that was a generalization. Infections and the immune responses they induce in different people are “heterogeneous,” said Sarah Cobey, an epidemiologist and evolutionary biologist at the University of Chicago.Older people often generate weaker levitra 10mg dosage immune responses than younger people.

Some studies have also indicated that milder cases of Covid-19 induce tamer immune responses that might not provide as lasting or as thorough of a defense as stronger immune responses. The man levitra 10mg dosage in Hong Kong, for example, did not generate antibodies to the virus after his first infection, at least to the level that could be detected by blood tests. Perhaps that explains why he contracted the virus again just about 4 1/2 months after recovering from his initial infection.In the Nevada case, researchers did not test what kind of immune response the man generated after the first case.“Infection is not some binary event,” Cobey said. And with reinfection, “there’s going to be some viral replication, but the question is levitra 10mg dosage how much is the immune system getting engaged?.

€What might be broadly meaningful is when people who mounted robust immune responses start getting reinfected, and how severe their second cases are. Are people who have Covid-19 a second time levitra 10mg dosage infectious?. As discussed, immune memory can prevent reinfection. If it can’t, it might stave off serious levitra 10mg dosage illness.

But there’s a third aspect of this, too.“The most important question for reinfection, with the most serious implications for controlling the pandemic, is whether reinfected people can transmit the virus to others,” Columbia University virologist Angela Rasmussen wrote in Slate this week.Unfortunately, neither the Hong Kong nor the Reno studies looked at this question. But if most people who get reinfected levitra 10mg dosage don’t spread the virus, that’s obviously good news. What happens when people broadly become susceptible again?. Whether it’s six months after the first infection or nine months or a year or longer, at some point, protection for most people who recover from Covid-19 levitra 10mg dosage is expected to wane.

And without the arrival of a vaccine and broad uptake of it, that could change the dynamics of local outbreaks.In some communities, it’s thought that more than 20% of residents have experienced an initial Covid-19 case, and are thus theoretically protected from another case for some time. That is still below the point of herd immunity — when enough people are immune that transmission doesn’t occur — but still, the fewer vulnerable people there are, the less likely spread is to occur.On the flip levitra 10mg dosage side though, if more people become susceptible to the virus again, that could increase the risk of transmission. Modelers are starting to factor that possibility into their forecasts.A crucial question for which there is not an answer yet is whether what happened to the man in Reno, where the second case was more severe than the first, remains a rare occurrence, as researchers expect and hope. As the Nevada researchers wrote, “the generalizability of this finding is unknown.”An advocacy group has asked the Department of Defense to investigate what it called “an apparent failure” by levitra 10mg dosage Moderna (MRNA) to disclose millions of dollars in awards received from the Defense Advanced Research Projects Agency in patent applications the company filed for vaccines.In a letter to the agency, Knowledge Ecology International explained that a review of dozens of patent applications found the company received approximately $20 million from the federal government in grants several years ago and the funds “likely” led to the creation of its vaccine technology.

This was used to develop vaccines to combat different viruses, such as Zika and, later, the virus that causes Covid-19.In arguing for an investigation, the advocacy group maintained Moderna is obligated under federal law to disclose the grants that led to nearly a dozen specific patent applications and explained the financial support means the U.S. Government would have certain rights levitra 10mg dosage over the patents. In other words, U.S. Taxpayers would have an ownership stake in vaccines levitra 10mg dosage developed by the company.advertisement “This clarifies the public’s right in the inventions,” said Jamie Love, who heads Knowledge Ecology International, a nonprofit that tracks patents and access to medicines issues.

€œThe disclosure (also) http://sw.keimfarben.de/buy-levitra-online/ changes the narrative about who has financed the inventive activity, often the most risky part of development.” advertisement One particular patent assigned to Moderna concerns methods and compositions that can be used specifically against coronaviruses, including COVID-19. The patent names a Moderna scientist and a former Moderna scientist as inventors, both of which acknowledged performing work under the DARPA awards in two academic papers, according to the report by the advocacy group.The group examined the 126 patents assigned to Moderna or ModernaTx as well as 154 patent applications. €œDespite the evidence that multiple inventions were conceived in the course of research supported by the DARPA awards, not a single one of the patents levitra 10mg dosage or applications assigned to Moderna disclose U.S. Federal government funding,” the report stated.We asked Moderna and the Department of Defense for comment and will update you accordingly.The missive to the Department of Defense follows a recent analysis by Public Citizen, another advocacy group, indicating the National Institutes of Health may own mRNA-1273, the Moderna vaccine candidate for Covid-19.

The advocacy group noted the federal government filed multiple patents covering the vaccine and two patent applications, in particular, list federal scientists as co-inventors.The analyses are part of a larger campaign levitra 10mg dosage among advocacy groups and others in the U.S. And elsewhere to ensure that Covid-19 medical products are available to poor populations around the world. The concern levitra 10mg dosage reflects the unprecedented global demand for therapies and vaccines, and a race among wealthy nations to snap up supplies from vaccine makers. In the U.S., the effort has focused on the extent to which the federal government has provided taxpayer dollars to different companies to help fund their discoveries.

In some levitra 10mg dosage cases, advocates argue that federal funding matters because it clarifies the rights that the U.S. Government has to ensure a therapy or vaccine is available to Americans on reasonable terms.One example has been remdesivir, the Gilead Sciences (GILD) treatment being given to hospitalized Covid-19 patients. The role played by the levitra 10mg dosage U.S. Government in developing remdesivir to combat coronaviruses involved contributions from government personnel at such agencies as the U.S.

Army Medical Research Institute of Infectious Diseases.As for the Moderna vaccine, earlier this month, the company was awarded a $1.525 billion contract by the Department of Defense and the Department levitra 10mg dosage of Health and Human Services to manufacture and deliver 100 million doses of its Covid-19 vaccine. The agreement also includes an option to purchase another 400 million doses, although the terms were not disclosed. In announcing the agreement, the government said it would ensure Americans receive the Covid-19 vaccine at no cost, although they may be charged by health care providers for administering a levitra 10mg dosage shot.In this instance, however, Love said the “letter is not about price or profits. It’s about (Moderna) not owning up to DARPA funding inventions.

If the levitra 10mg dosage U.S. Wants to pay for all of the development of Moderna’s vaccine, as Moderna now acknowledges, and throw in a few more billion now, and an option to spend billions more, it’s not unreasonable to have some transparency over who paid for their inventions.”This is not the first time Moderna has been accused of insufficient disclosure. Earlier this month, Knowledge Ecology International and Public Citizen maintained the company failed to disclose development costs in a $955 million levitra 10mg dosage contract awarded by BARDA for its Covid-19 vaccine. In all, the federal government has awarded the company approximately $2.5 billion to develop the vaccine.The coming few weeks represent a crucial moment for an ambitious plan to try to secure Covid-19 vaccines for roughly 170 countries around the world without the deep pockets to compete for what will be scarce initial supplies.Under the plan, countries that want to pool resources to buy vaccines must notify the World Health Organization and other organizers — Gavi, the Vaccine Alliance, as well as the Coalition for Epidemic Preparedness Innovations — of their intentions by Monday.

That means it’s fish-or-cut-bait time for the so-called COVAX facility.Already, wealthy countries — the United States, levitra 10mg dosage the United Kingdom, Japan, Canada, and Australia, among others, as well as the European Union — have opted to buy their own vaccine, signing bilateral contracts with manufacturers that have secured billions of doses of vaccine already. That raises the possibility that less wealthy countries will be boxed out of supplies.advertisement And yet Richard Hatchett, the CEO of CEPI, insists there is a path to billions of doses of vaccine for the rest of the world in 2021. STAT spoke levitra 10mg dosage with Hatchett this week. A transcript of the conversation, lightly edited for clarity and length, follows.

You said this is levitra 10mg dosage a critical time for CEPI. Can you explain what needs to happen between now and mid-September for this joint purchasing approach to be a success?. Advertisement The critical moment is now for countries to commit to the COVAX facility, because that will enable us to secure ample quantities of vaccine and then to be able to convey when that vaccine is likely to become available based on current information.What we’re now here asking countries to do is to indicate their intent to participate by Aug levitra 10mg dosage. 31, and to make a binding commitment by Sept.

18. And to provide funds in support of that binding commitment by early October. Our negotiations with companies are already taking place and it will be important for us from a planning purpose that countries indicate their intent to participate.Those binding commitments we think will be sufficient to allow us to then secure the advance purchase agreements, particularly with those companies that don’t have a prior contractual obligation to COVAX. And then obviously, we need the funds to live up to those advance purchase agreements.Is it possible this thing could still fall apart?.

There appears to be some concern COVAX has been boxed out by rich countries. There was always a possibility that there wouldn’t be sufficient uptake. But I think we’re very encouraged at this point by the level of commitment, both from countries that would be beneficiaries of the advance market commitment — that’s the lower-income, lower-middle-income countries — as well as the self-financing countries. To have over 170 countries expressing interest in participating — they see the value.We’re much more encouraged now that it’s not going to fall apart.

We still need to bring it off to maximize its value. And we’re right at the crunch moment where countries are going to have to make these commitments. So, the next month is really absolutely critical to the facility. I am confident at this point that the world recognizes the value and wants it to work.I’ve been keeping tabs on advance purchase agreements that have been announced.

And at this point, a small number of rich countries have nailed down a lot of vaccine — more than 3 billion doses. How hard does that make your job?. The fact that they’re doing it creates anxiety among other countries. And that in itself can accelerate the pace.

So, I’m not going to say that we’re not watching that with concern.I will say that for COVAX and the facility, this is absolutely critical moment. I think we still have a window of opportunity between now and mid-September — when we’re asking that the self-financing countries to make their commitments — to make the facility real and to make it work. Between doses that are committed to COVAX through the access agreements and other agreements — these are discussions with partners that CEPI has funded as well as partners that CEPI has not funded — we still see a pathway for COVAX to well over 3 billion doses in 2021.I think it’s really important to bear in mind is that there are at least a few countries — and I think the U.S. And the U.K.

Most publicly — that may be in a situation of significant oversupply. I believe the U.S. And U.K. Numbers, if you add them together, would result in enough vaccine for 600 million people to receive two doses of vaccine each.

And, you know, there is no possible way that the U.S. Or the U.K. Can use that much vaccine.So, there may be a lot of extra supply that looks like it’s been tied up sloshing around later. I don’t think that the bilateral deals that have been struck are going to prevent COVAX from achieving its goals.But if so much vaccine has been pre-ordered by rich countries, can countries in the COVAX pool get enough for their needs?.

One of the things that we’ve argued through COVAX is that to control the pandemic or to end the acute phase of the pandemic to allow normalcy to start to reassert itself, you don’t have to vaccinate 100% of your population.You need to vaccinate those at greatest risk for bad outcomes and you need to vaccinate certain critical workers, particularly your health care workforce. And if you can achieve that goal, which for most countries means vaccinating between 20% and maybe 30% of the population, then you can transform the pandemic into something that is much more manageable. Then you can buy yourself time to vaccinate everybody who wants to be vaccinated.We’ve argued the COVAX facility really offers the world the best shot at doing that globally in the fastest possible way, as well as providing for equitable access. This is a case where doing the equitable thing is also doing the efficient thing.CEPI has provided funding to nine vaccines.

Is it true that all those manufacturers aren’t required to provide the COVAX facility with vaccine?. That is correct. One of the things that we did, and I think it was an important role that CEPI played early on, was that we moved money very, very quickly, in small increments. You know, some of the early contracts were only $5 million or $10 million, to get programs up and running while we potentially put in place much larger-scale, longer-term contracts.If you were doing it over again, would you have given money without strings attached?.

Yes, I think I would have. I think that was critically important to initiating programs.Our contract with Moderna was established in about 48 hours. And that provided critical funding to them to manufacture doses that got them into clinical trials within nine weeks of the genetic sequences [of the SARS-CoV-2 virus] being released.And if you look at the nine programs that we’ve invested in, seven are in clinical trials. Two — the AstraZeneca program now and the Moderna program — are among the handful in Phase 3 clinical trials.

And, I think the number of projects that that we funded initially, which started in kind of a biotech or academic phase that have now been picked up by large multinational corporations, there’s at least four. The Themis program being picked up by Merck, Oxford University by AstraZeneca, the University of Queensland by CSL, and Clover being in partnership with GSK, I think that speaks to the quality of the programs that we selected.So, I think that combination of rapid review, speed of funding, getting those programs started, getting them oriented in the right direction, I think all of that is critical to where we are now.Companies that got money from CEPI to build out production capacity — that money came with strings attached, right?. Yes, exactly. So, where CEPI has made investments that create manufacturing, or secure manufacturing capacity, the commitment has been that the capacity that is attributable to the CEPI investment is committed — at least right of first refusal — to the global procurement facility.WASHINGTON — The Trump administration removed a top Food and Drug Administration communications official from her post on Friday in the wake of several controversial agency misstatements, a senior administration official confirmed to STAT.The spokeswoman, Emily Miller, had played a lead role in defending the FDA commissioner, Stephen Hahn, after he misrepresented data regarding the use of blood plasma from recovered Covid-19 patients.

The New York Times first reported Miller’s ouster. Miller’s tenure at as the top FDA spokeswoman lasted only 11 days. Her appointment was viewed with alarm by agency officials who felt her presence at the agency was emblematic of broader political pressure from the Trump administration, STAT first reported earlier this week.advertisement Before joining the FDA, Miller had no experience in health or medicine. Her former role as assistant commissioner for media affairs is typically not an appointment filled by political appointees.

The FDA’s communications arm typically maintains a neutral, nonpolitical tone.Miller’s appointment particularly alarmed FDA staff and outside scientists given her history in right-wing political advocacy and conservatism journalism. Her résumé included a stint as a Washington Times columnist, where she penned columns with titles that include “New Obamacare ads make young women look like sluts,” and a 2013 book on gun rights titled “Emily Gets Her Gun. But Obama Wants to Take Yours.”advertisement She also worked as a reporter for One America News Network, a right-wing cable channel that frequently espouses conspiracy theories and has declared an open alliance with President Trump.Miller quickly made her presence known at the FDA. In the wake of Hahn’s misstatements on blood plasma, she aggressively defended the commissioner, falsely claiming in a tweet that the therapy “has shown to be beneficial for 35% of patients.” An FDA press release on blood plasma, issued less than a week after her appointment, similarly alarmed agency insiders by trumpeting the emergency authorization as “Another Achievement in Administration’s Fight Against [the] Pandemic.”.

Elon Musk on Friday unveiled a coin-sized prototype of a brain implant developed by his startup Neuralink to enable people who are paralyzed to levitra cheap online operate smartphones and robotic limbs with their thoughts — and said the company had worked to “dramatically simplify” the levitra walgreens device since presenting an earlier version last summer.In an event live-streamed on YouTube to more than 150,000 viewers at one point, the company staged a demonstration in which it trotted out a pig named Gertrude that was said to have had the company’s device implanted in its head two months ago. The live stream showed what Musk claimed to be Gertrude’s real-time brain activity as it sniffed around a pen. At no point, though, did levitra cheap online he provide evidence that the signals — rendered in beeps and bright blue wave patterns on screen — were, in fact, emanating from the pig’s brain.A pig presented at a Neuralink demonstration was said to have one of the company’s brain implants in its head. YouTube screenshot“This is obviously sounding increasingly like a Black Mirror episode,” Musk said at one point during the event as he responded affirmatively to a question about whether the company’s implant could eventually be used to save and replay memories. €œThe future’s going to be weird.”advertisement Musk said that in July Neuralink received a breakthrough device designation from the Food and Drug Administration — a regulatory pathway that could allow the company to soon start a clinical trial levitra cheap online in people with paraplegia and tetraplegia.

The big reveal came after four former Neuralink employees told STAT that the company’s leaders have long fostered an internal culture characterized by rushed timelines and the “move fast and break things” ethos of a tech company — a pace sometimes at odds with the slow and incremental pace that’s typical of medical device development. Advertisement Friday’s event began, 40 minutes late, with levitra cheap online a glossy video about the company’s work — and then panned to Musk, standing in front of a blue curtain beside a gleaming new version of the company’s surgical “sewing machine” robot that could easily have been mistaken for a giant Apple device. Musk described the event as a “product demo” and said its primary purpose was to recruit potential new employees. It was unclear whether the demonstration was taking place at the company’s Fremont, levitra cheap online Calif., headquarters or elsewhere. Musk proceeded to reveal the new version of Neuralink’s brain implant, which he said was designed to fit snugly into the top of the skull.

Neuralink’s technological design has changed significantly since its last big levitra cheap online update in July 2019. At that time, the company’s brain implant system involved a credit-card sized device designed to be positioned behind the back of a person’s ear, with several wires stretching to the top of the skull. After demonstrating the pig’s brain activity at Friday’s event, Musk showed video footage of a pig walking on a treadmill and said Neuralink’s device could be used to “predict the position of limbs with high accuracy.” That capability would be critical to allowing someone using the device to do something like controlling a prosthetic limb, for example.Neuralink for months levitra cheap online has signaled that it initially plans to develop its device for people who are paralyzed. It said at its July 2019 event that it wanted to start human testing by the end of 2020. Receiving the breakthrough device designation from the FDA — designed levitra cheap online to speed up the lengthy regulatory process — is a step forward, but it by no means guarantees that a device will receive a green light, either in a short or longer-term time frame.

After Musk’s presentation, a handful of the company’s employees — all wearing masks, but seated only inches apart — joined him to take questions submitted on Twitter or from the small audience in the room.In typical fashion for a man who in 2018 sent a Tesla Roadster into space, Musk didn’t hesitate to use the event to cross-promote his electric car company. Asked whether the levitra cheap online Neuralink chip would allow people to summon their Tesla telepathically, Musk responded. €œDefinitely — of course.”Matthew MacDougall, the company’s head neurosurgeon, appearing in scrubs, said the company had so far only implanted its technology into the brain’s cortical surface, the coaster-width layer enveloping the brain, but added that it hoped to go deeper in the future. Still, Musk levitra cheap online said. €œYou could solve blindness, you could solve paralysis, you could solve hearing — you can solve a lot just by interfacing with the cortex.”Musk and MacDougall said they hoped to eventually implant Neuralink’s devices — which they referred to on stage simply as “links” — in the deeper structures of the brain, such as in the hypothalamus, which is believed to play a critical role in mental illnesses including depression, anxiety, and PTSD.There were no updates at the event of Neuralink’s research in monkeys, which the company has been conducting in partnership with the University of California, Davis since 2017.

At last July’s event, levitra cheap online Musk said — without providing evidence — that a monkey had controlled a computer with its brain.At that same July 2019 event, Neuralink released a preprint paper — published a few months later — that claimed to show that a series of Neuralink electrodes implanted in the brains of rats could record neural signals. Critically, the work did not show where in the brain the implanted electrodes were recording from, for how long they were recording, or whether the recordings could be linked to any of the rats’ bodily movements.In touting Friday’s event — and Neuralink’s technological capabilities — on Twitter in recent weeks, Musk spoke of “AI symbiosis while u wait” and referenced the “matrix in the matrix” — a science-fiction reference about revealing the true nature of reality. The progress the company levitra cheap online reported on Friday fell far short of that. Neuralink’s prototype is ambitious, but it has yet to show evidence that it can match up to the brain-machine interfaces developed by academic labs and other companies. Other groups have shown that they can listen in on neural activity and allow primates and people to control a computer cursor levitra cheap online with their brain — so-called “read-out” technology — and have also shown that they can use electrical stimulation to input information, such as a command or the heat of a hot cup of coffee, using “write-in” technology.

Neuralink said on Friday that its technology would have both read-out and write-in capabilities.Musk acknowledged that Neuralink still has a long way to go. In closing the event after more than levitra cheap online 70 minutes, Musk said. €œThere’s a tremendous amount of work to be done to go from here to a device that is widely available and affordable and reliable.”Following the news this week of what appears to have been the first confirmed case of a Covid-19 reinfection, other researchers have been coming forward with their own reports. One in levitra cheap online Belgium, another in the Netherlands. And now, one in Nevada.What caught experts’ attention about the case of the 25-year-old Reno man was not that he appears to have contracted SARS-CoV-2 (the name of the virus that causes Covid-19) a second time.

Rather, it’s that his second levitra cheap online bout was more serious than his first.Immunologists had expected that if the immune response generated after an initial infection could not prevent a second case, then it should at least stave off more severe illness. That’s what occurred with the first known reinfection case, in a 33-year-old Hong Kong man.advertisement Still, despite what happened to the man in Nevada, researchers are stressing this is not a sky-is-falling situation or one that should result in firm conclusions. They always presumed people would become vulnerable to Covid-19 levitra cheap online again some time after recovering from an initial case, based on how our immune systems respond to other respiratory viruses, including other coronaviruses. It’s possible that these early cases of reinfection are outliers and have features that won’t apply to the tens of millions of other people who have already shaken off Covid-19.“There are millions and millions of cases,” said Michael Mina, an epidemiologist at Harvard’s T.H. Chan School of Public levitra cheap online Health.

The real question that should get the most focus, Mina said, is, “What happens to most people?. €advertisement But with more reinfection reports likely to make levitra cheap online it into the scientific literature soon, and from there into the mainstream press, here are some things to look for in assessing them.What’s the deal with the Nevada case?. The Reno resident in question first tested positive for SARS-CoV-2 in April after coming down with a sore throat, cough, and headache, as well as nausea and diarrhea. He got better over time and later tested levitra cheap online negative twice. But then, some 48 days later, the man started experiencing headaches, cough, and other symptoms again.

Eventually, he became so sick that he had to be hospitalized and was found to have pneumonia.Researchers sequenced virus samples from both of his infections and found they were different, providing evidence that this was a new infection distinct from the first. What happens when we get Covid-19 in the first case? levitra cheap online. Researchers are finding that, generally, people who get Covid-19 develop a healthy immune response replete with both antibodies (molecules that can block pathogens from infecting cells) and T cells (which help wipe out the virus). This is what happens after other viral infections.In addition to fending off the virus the first time, levitra cheap online that immune response also creates memories of the virus, should it try to invade a second time. It’s thought, then, that people who recover from Covid-19 will typically be protected from another case for some amount of time.

With other coronaviruses, protection is thought to last for perhaps a little less levitra cheap online than a year to about three years.But researchers can’t tell how long immunity will last with a new pathogen (like SARS-CoV-2) until people start getting reinfected. They also don’t know exactly what mechanisms provide protection against Covid-19, nor do they know what levels of antibodies or T cells are required to signal that someone is protected through a blood test. (These are levitra cheap online called the “correlates of protection.”) Why do experts expect second cases to be milder?. With other viruses, protective immunity doesn’t just vanish one day. Instead, it levitra cheap online wanes over time.

Researchers have then hypothesized that with SARS-CoV-2, perhaps our immune systems might not always be able to prevent it from getting a toehold in our cells — to halt infection entirely — but that it could still put up enough of a fight to guard us from getting really sick. Again, this is what happens with other respiratory pathogens.And it’s why some researchers actually looked at levitra cheap online the Hong Kong case with relief. The man had mild to moderate Covid-19 symptoms during the first case, but was asymptomatic the second time. It was a levitra cheap online demonstration, experts said, of what you would want your immune system to do. (The case was only detected because the man’s sample was taken at the airport when he arrived back in Hong Kong after traveling in Europe.)“The fact that somebody may get reinfected is not surprising,” Malik Peiris, a virologist at the University of Hong Kong, told STAT earlier this week about the first reinfection.

€œBut the reinfection didn’t cause disease, so that’s the first point.”The Nevada case, levitra cheap online then, provides a counterexample to that. What kind of immune response did the person who was reinfected generate initially?. Earlier, we described the robust immune response that most people who have Covid-19 seem to mount levitra cheap online. But that was a generalization. Infections and the immune responses they induce in different people are “heterogeneous,” said Sarah Cobey, levitra cheap online an epidemiologist and evolutionary biologist at the University of Chicago.Older people often generate weaker immune responses than younger people.

Some studies have also indicated that milder cases of Covid-19 induce tamer immune responses that might not provide as lasting or as thorough of a defense as stronger immune responses. The man levitra cheap online in Hong Kong, for example, did not generate antibodies to the virus after his first infection, at least to the level that could be detected by blood tests. Perhaps that explains why he contracted the virus again just about 4 1/2 months after recovering from his initial infection.In the Nevada case, researchers did not test what kind of immune response the man generated after the first case.“Infection is not some binary event,” Cobey said. And with levitra cheap online reinfection, “there’s going to be some viral replication, but the question is how much is the immune system getting engaged?. €What might be broadly meaningful is when people who mounted robust immune responses start getting reinfected, and how severe their second cases are.

Are people who have Covid-19 a levitra cheap online second time infectious?. As discussed, immune memory can prevent reinfection. If it can’t, it might stave levitra cheap online off serious illness. But there’s a third aspect of this, too.“The most important question for reinfection, with the most serious implications for controlling the pandemic, is whether reinfected people can transmit the virus to others,” Columbia University virologist Angela Rasmussen wrote in Slate this week.Unfortunately, neither the Hong Kong nor the Reno studies looked at this question. But if most people who levitra cheap online get reinfected don’t spread the virus, that’s obviously good news.

What happens when people broadly become susceptible again?. Whether it’s six months after the first infection or nine months or a year or levitra cheap online longer, at some point, protection for most people who recover from Covid-19 is expected to wane. And without the arrival of a vaccine and broad uptake of it, that could change the dynamics of local outbreaks.In some communities, it’s thought that more than 20% of residents have experienced an initial Covid-19 case, and are thus theoretically protected from another case for some time. That is still below the point of herd immunity — when enough people are immune that transmission doesn’t levitra cheap online occur — but still, the fewer vulnerable people there are, the less likely spread is to occur.On the flip side though, if more people become susceptible to the virus again, that could increase the risk of transmission. Modelers are starting to factor that possibility into their forecasts.A crucial question for which there is not an answer yet is whether what happened to the man in Reno, where the second case was more severe than the first, remains a rare occurrence, as researchers expect and hope.

As the Nevada researchers wrote, “the generalizability of this finding is unknown.”An advocacy group has asked the Department of Defense to investigate what it called “an apparent failure” by Moderna (MRNA) to disclose millions of dollars in awards levitra cheap online received from the Defense Advanced Research Projects Agency in patent applications the company filed for vaccines.In a letter to the agency, Knowledge Ecology International explained that a review of dozens of patent applications found the company received approximately $20 million from the federal government in grants several years ago and the funds “likely” led to the creation of its vaccine technology. This was used to develop vaccines to combat different viruses, such as Zika and, later, the virus that causes Covid-19.In arguing for an investigation, the advocacy group maintained Moderna is obligated under federal law to disclose the grants that led to nearly a dozen specific patent applications and explained the financial support means the U.S. Government would have certain levitra cheap online rights over the patents. In other words, U.S. Taxpayers would have an ownership stake in vaccines developed by the company.advertisement “This clarifies the levitra cheap online public’s right in the inventions,” said Jamie Love, who heads Knowledge Ecology International, a nonprofit that tracks patents and access to medicines issues.

€œThe disclosure (also) changes the narrative about who has financed the inventive how much levitra can you take activity, often the most risky part of development.” advertisement One particular patent assigned to Moderna concerns methods and compositions that can be used specifically against coronaviruses, including COVID-19. The patent names a Moderna scientist and a former Moderna scientist as inventors, both of which acknowledged performing work under the DARPA awards in two academic papers, according to the report by the advocacy group.The group examined the 126 patents assigned to Moderna or ModernaTx as well as 154 patent applications. €œDespite the evidence that multiple inventions were conceived in the course of research supported by the DARPA awards, not a single levitra cheap online one of the patents or applications assigned to Moderna disclose U.S. Federal government funding,” the report stated.We asked Moderna and the Department of Defense for comment and will update you accordingly.The missive to the Department of Defense follows a recent analysis by Public Citizen, another advocacy group, indicating the National Institutes of Health may own mRNA-1273, the Moderna vaccine candidate for Covid-19. The advocacy group noted the federal government filed levitra cheap online multiple patents covering the vaccine and two patent applications, in particular, list federal scientists as co-inventors.The analyses are part of a larger campaign among advocacy groups and others in the U.S.

And elsewhere to ensure that Covid-19 medical products are available to poor populations around the world. The concern reflects the unprecedented global demand for therapies and vaccines, and a race among wealthy nations to levitra cheap online snap up supplies from vaccine makers. In the U.S., the effort has focused on the extent to which the federal government has provided taxpayer dollars to different companies to help fund their discoveries. In some cases, advocates argue levitra cheap online that federal funding matters because it clarifies the rights that the U.S. Government has to ensure a therapy or vaccine is available to Americans on reasonable terms.One example has been remdesivir, the Gilead Sciences (GILD) treatment being given to hospitalized Covid-19 patients.

The role played by levitra cheap online the U.S. Government in developing remdesivir to combat coronaviruses involved contributions from government personnel at such agencies as the U.S. Army Medical Research Institute of Infectious Diseases.As for the Moderna vaccine, earlier this month, the company was awarded a $1.525 billion contract by the Department of Defense and the Department of Health and Human Services to manufacture and deliver 100 levitra cheap online million doses of its Covid-19 vaccine. The agreement also includes an option to purchase another 400 million doses, although the terms were not disclosed. In announcing the agreement, the government said it would ensure Americans receive the Covid-19 vaccine at no cost, although they may levitra cheap online be charged by health care providers for administering a shot.In this instance, however, Love said the “letter is not about price or profits.

It’s about (Moderna) not owning up to DARPA funding inventions. If the levitra cheap online U.S. Wants to pay for all of the development of Moderna’s vaccine, as Moderna now acknowledges, and throw in a few more billion now, and an option to spend billions more, it’s not unreasonable to have some transparency over who paid for their inventions.”This is not the first time Moderna has been accused of insufficient disclosure. Earlier this month, Knowledge Ecology International levitra cheap online and Public Citizen maintained the company failed to disclose development costs in a $955 million contract awarded by BARDA for its Covid-19 vaccine. In all, the federal government has awarded the company approximately $2.5 billion to develop the vaccine.The coming few weeks represent a crucial moment for an ambitious plan to try to secure Covid-19 vaccines for roughly 170 countries around the world without the deep pockets to compete for what will be scarce initial supplies.Under the plan, countries that want to pool resources to buy vaccines must notify the World Health Organization and other organizers — Gavi, the Vaccine Alliance, as well as the Coalition for Epidemic Preparedness Innovations — of their intentions by Monday.

I think we still have a window of opportunity between now and mid-September — when we’re asking that the self-financing countries to make their commitments — to make the facility real and to make it work. Between doses that are committed to COVAX through the access agreements and other agreements — these are discussions with partners that CEPI has funded as well as partners that CEPI has not funded — we still see a pathway for COVAX to well over 3 billion doses in 2021.I think it’s really important to bear in mind is that there are at least a few countries — and I think the U.S. And the U.K. Most publicly — that may be in a situation of significant oversupply. I believe the U.S.

And U.K. Numbers, if you add them together, would result in enough vaccine for 600 million people to receive two doses of vaccine each. And, you know, there is no possible way that the U.S. Or the U.K. Can use that much vaccine.So, there may be a lot of extra supply that looks like it’s been tied up sloshing around later.

This is a case where doing the equitable thing is also doing the efficient thing.CEPI has provided funding to nine vaccines.

Is it true that all those manufacturers aren’t required to provide the COVAX facility with vaccine?. That is correct. One of the things that we did, and I think it was an important role that CEPI played early on, was that we moved money very, very quickly, in small increments. You know, some of the early contracts were only $5 million or $10 million, to get programs up and running while we potentially put in place much larger-scale, longer-term contracts.If you were doing it over again, would you have given money without strings attached?. Yes, I think I would have.

I think that was critically important to initiating programs.Our contract with Moderna was established in about 48 hours. And that provided critical funding to them to manufacture doses that got them into clinical trials within nine weeks of the genetic sequences [of the SARS-CoV-2 virus] being released.And if you look at the nine programs that we’ve invested in, seven are in clinical trials. Two — the AstraZeneca program now and the Moderna program — are among the handful in Phase 3 clinical trials. And, I think the number of projects that that we funded initially, which started in kind of a biotech or academic phase that have now been picked up by large multinational corporations, there’s at least four. The Themis program being picked up by Merck, Oxford University by AstraZeneca, the University of Queensland by CSL, and Clover being in partnership with GSK, I think that speaks to the quality of the programs that we selected.So, I think that combination of rapid review, speed of funding, getting those programs started, getting them oriented in the right direction, I think all of that is critical to where we are now.Companies that got money from CEPI to build out production capacity — that money came with strings attached, right?.

Yes, exactly. So, where CEPI has made investments that create manufacturing, or secure manufacturing capacity, the commitment has been that the capacity that is attributable to the CEPI investment is committed — at least right of first refusal — to the global procurement facility.WASHINGTON — The Trump administration removed a top Food and Drug Administration communications official from her post on Friday in the wake of several controversial agency misstatements, a senior administration official confirmed to STAT.The spokeswoman, Emily Miller, had played a lead role in defending the FDA commissioner, Stephen Hahn, after he misrepresented data regarding the use of blood plasma from recovered Covid-19 patients. The New York Times first reported Miller’s ouster. Miller’s tenure at as the top FDA spokeswoman lasted only 11 days. Her appointment was viewed with alarm by agency officials who felt her presence at the agency was emblematic of broader political pressure from the Trump administration, STAT first reported earlier this week.advertisement Before joining the FDA, Miller had no experience in health or medicine.

Her former role as assistant commissioner for media affairs is typically not an appointment filled by political appointees. The FDA’s communications arm typically maintains a neutral, nonpolitical tone.Miller’s appointment particularly alarmed FDA staff and outside scientists given her history in right-wing political advocacy and conservatism journalism. Her résumé included a stint as a Washington Times columnist, where she penned columns with titles that include “New Obamacare ads make young women look like sluts,” and a 2013 book on gun rights titled “Emily Gets Her Gun. But Obama Wants to Take Yours.”advertisement She also worked as a reporter for One America News Network, a right-wing cable channel that frequently espouses conspiracy theories and has declared an open alliance with President Trump.Miller quickly made her presence known at the FDA. In the wake of Hahn’s misstatements on blood plasma, she aggressively defended the commissioner, falsely claiming in a tweet that the therapy “has shown to be beneficial for 35% of patients.” An FDA press release on blood plasma, issued less than a week after her appointment, similarly alarmed agency insiders by trumpeting the emergency authorization as “Another Achievement in Administration’s Fight Against [the] Pandemic.”.
