Buy kamagra online usa

When are we getting more erectile dysfunction treatment data? buy kamagra online usa. Is CRISPR buy kamagra online usa having a dot-com moment?. And how to separate disinformation from healthy dissent?. We discuss all that and buy kamagra online usa more this week on “The Readout LOUD,” STAT’s biotech podcast.

First, we discuss the implications of Johnson &. Johnson’s any-day-now buy kamagra online usa data on a one-shot treatment for erectile dysfunction treatment. Then, Kevin Davies, executive editor of the CRISPR Journal, joins us to talk about the strange boom in genome editing stocks and the future of the revolutionary technology. Finally, we talk to Megan Ranney, an emergency room physician and buy kamagra online usa Brown University professor, about the challenges of erectile dysfunction treatment science communication in a post-Trump world.

For more on what we cover, here’s the latest from J&J. Here’s where you can buy kamagra online usa find Davies’s CRISPR book. And here’s our complete coverage of the erectile dysfunction kamagra.advertisement Be sure to sign up on Apple Podcasts, Stitcher, Google Play, or wherever you get your podcasts.And if you have any feedback for us — topics to cover, guests to invite, vocal tics to cease — you can email readoutloud@statnews.com.advertisement Interested in sponsoring a future episode of “The Readout LOUD”?. Email us at marketing@statnews.com.A erectile dysfunction treatment from Novavax proved nearly 90% effective in preliminary results from a key clinical trial in the United Kingdom, the company said, but in buy kamagra online usa a separate trial appeared far less effective against a new variant of the erectile dysfunction that was first identified in South Africa.In its 15,000-volunteer U.K.

Trial, Novavax said, the treatment prevented nine in 10 cases, including against a new strain of the kamagra that is circulating there. But in a 4,400-volunteer study in South Africa, buy kamagra online usa the treatment proved only 49% effective. In the 94% of the study population buy kamagra online usa that did not have HIV, the efficacy was 60%. In the U.K.

Trial, Novavax observed 62 cases of buy kamagra online usa symptomatic erectile dysfunction treatment, with 56 in the placebo group and six among volunteers who got the treatment. One patient on placebo developed severe erectile dysfunction treatment, compared with zero in the treatment group. The company provided few details on the treatment’s safety, saying buy kamagra online usa only that the serious side effects were rare and balanced between the studies’ treatment and placebo groups.advertisement In the South African study, 29 cases of symptomatic erectile dysfunction treatment were observed in the placebo group, and 15 in the treatment group. It’s unclear whether these data will be enough for U.S.

Approval, or buy kamagra online usa if the U.S. Will wait for further data, as it appears to be doing with treatments developed by AstraZeneca and Oxford University. Novavax said it expects to file buy kamagra online usa for an emergency authorization in the U.K. In the coming months, once it has final data from its clinical trial there.

The company said it has been in contact with the Food and Drug Administration but didn’t provide buy kamagra online usa details on its plans.advertisement Operation Warp Speed, the U.S. Government’s treatment incubator, is running its own large U.S. Trial of the Novavax treatment in the United States buy kamagra online usa and Mexico. Researchers expect to complete enrollment in the first half of February.Carlos del Rio, a professor of infectious diseases at the Emory University School of Medicine, said the overall efficacy numbers were impressive, and that the treatment showed at least some efficacy against the variant first identified in South Africa.By the same token, the lower efficacy against that variant could be a vulnerability in the United States, where it was first reported in South Carolina on Thursday, and elsewhere.Nahid Bhadelia, medical director of the special pathogens unit at Boston Medical Center, emphasized that although the drop in efficacy against the South African variant is bad news, the results aren’t “a complete wash.” The treatment, she said, “can still make a huge difference.” But the results also emphasize buy kamagra online usa the important work of figuring out how to develop booster shots against new variants, especially given the news that the South Africa strain, B1351, was found in South Carolina.Novavax said it is already at work on a new version of the treatment designed to combat more infectious strains of erectile dysfunction, which could work as a booster shot for people already inoculated.

But clinical testing isn’t expected until the second quarter of this year.Some experts cautioned against over-interpreting the efficacy results in the South Africa trial, noting that they amounted to a relatively small number of cases in a preliminary analysis.“I am not sure that it is disappointing. The U.K buy kamagra online usa. Data look very good. The South buy kamagra online usa Africa data may be more nuanced,” said Anna Durbin, a professor at the Johns Hopkins Bloomberg School of Public Health, noting that each trial defined symptomatic disease slightly differently.

She said she would be interested in seeing more data on the severity of disease in the cases reported.Scott Gottlieb, the former FDA commissioner and Pfizer board member, said he didn’t think it was a surprise that the treatment was less effective against the new strain.“We have already seen experimentally that there is a falloff in neutralization against that variant with the other treatments, and we should expect that this may be common to all the treatments that use the original spike protein as the epitope, regardless of how that protein is being delivered,” he said.More data will be available with results from Johnson &. Johnson, expected soon, because that trial will include patients from both Brazil and South Africa.“I think this raises the stakes on putting boosters into development that are based on these new variants, and building a regulatory process that allows this sort of incremental, follow-on innovation to reach the market based on something short of brand new, full-blown outcomes studies,” Gottlieb said.Novavax’s data arrive as countries around the buy kamagra online usa world scramble to secure enough treatment doses to protect their populations. In the U.S., the federal government has struggled to meet demand for doses of the only two authorized treatments, from Moderna and partners Pfizer and BioNTech. Novavax has said buy kamagra online usa it expects to produce about 2 billion doses of its treatment in 2021.

The U.S. Has signed a contract to buy 100 buy kamagra online usa million of them and has the option to acquire more.Like all the erectile dysfunction treatments that are being used or are in final test, Novavax’s two-dose shot works by mimicking a protein called spike, which is found on the surface of erectile dysfunction. When the immune system catches sight of that protein, it produces antibodies against it, thereby protecting the body from a case of erectile dysfunction treatment.But Novavax is using the most tried-and-true technology among the frontrunners in the race to develop erectile dysfunction treatment. The first two buy kamagra online usa treatments authorized in the U.S.

Use a buy kamagra online usa technology called mRNA, which slips genetic material into cells to create a protein that stimulates the immune system. Others still in development, such as one from Johnson &. Johnson and another from AstraZeneca, use genetically altered kamagraes to do something similar.Like some approved treatments, Novavax’s treatment manufactures fragments of the spike protein in insect cells and then adds another chemical, called an adjuvant, to buy kamagra online usa stimulate the immune system to respond. This approach is used in an approved flu treatment sold by Sanofi, and was the approach that Sanofi and GlaxoSmithKline planned to use in their own erectile dysfunction treatment.

The similarities are not entirely buy kamagra online usa coincidental. Gale Smith, the former chief scientific officer of the company that developed that treatment, is now a scientist at Novavax. But while the drug giants stumbled, Novavax, a small company that has not previously brought a product to market, has mostly hit its marks.The company presented promising early data in August that showed neutralizing antibody levels that were roughly quadruple those seen in patients who had recovered from erectile dysfunction treatment, among the best for any treatment buy kamagra online usa in early testing. Those same results were published in the New England Journal of Medicine in September.In July, Novavax received $1.6 billion in funding from Operation Warp Speed to scale up its manufacturing processes, with the agreement that the 100 million doses of treatment that would result would be owned by the U.S.

Government.The good news, said Natalie Dean, a biostatistician at the University of Florida, is that, from buy kamagra online usa the start, several different treatment technologies have been developed against erectile dysfunction treatment. That makes the world more ready for what comes next.“This is why it’s important to have an open pipeline,” Dean said. “At every stage we buy kamagra online usa want to not put all our eggs in one basket. And this is the same situation.

We still don’t know about durability, we don’t know how the treatments buy kamagra online usa work against different variants. At all stages we want a diversity of approaches.”.

So far, the response to this kamagra has been http://pedrotrotz.com/can-you-buy-viagra/ focused on addressing the acute manifestations of erectile dysfunction treatment -- but that is only the kamagra 100 tablets tip of the iceberg. We must not ignore what's beneath the surface. The lingering health and mental health implications of long erectile dysfunction treatment.Long kamagra 100 tablets after the initial should have resolved, a substantial number of people infected with erectile dysfunction continue to experience lingering health problems. Some patients even experience the emergence of new problems they did not have during the acute phase of the .

The constellation of clinical abnormalities that characterize this phase of the disease is now generally referred to as long erectile dysfunction treatment (or more officially, post-acute sequelae of erectile dysfunction, or PASC for kamagra 100 tablets short). People with long erectile dysfunction treatment have been dubbed long haulers. In addition to being at risk of long erectile dysfunction treatment, people who survive the acute phase of the erectile dysfunction treatment are also at increased risk of death. The death and suffering among 30-day erectile dysfunction treatment survivors will add kamagra 100 tablets to the already substantial toll of this kamagra.Long erectile dysfunction treatment Health RisksLong erectile dysfunction treatment is a multifaceted disease and can affect nearly every organ system and may result in serious chronic health conditions.

Our research has also uncovered a significant risk of mental health conditions. New onset kamagra 100 tablets depression, anxiety, substance use disorders, and increased risk of opioid use. We must deal with this now to prevent it from ballooning into a suicide crisis or another opioid epidemic.We also see a significant increased risk of serious conditions including heart disease (acute coronary disease, heart failure, arrhythmias), kidney disease (acute and chronic kidney disease), metabolic conditions (new onset diabetes), brain disorders (stroke, memory problems), and several other serious consequences. These are chronic conditions that have serious downstream ramifications on quality of life and life expectancy.

They will require multidisciplinary care.Evidence suggests that long kamagra 100 tablets erectile dysfunction treatment can happen in nearly anyone. Even those whose acute was mild and did not necessitate hospitalization during the acute phase of the are at risk. The risk kamagra 100 tablets in these people is small but not trivial. The risk is much higher in people who needed hospitalization, and is greatest among people who required intensive care during the acute phase of the .Estimates suggest that approximately 10% of people with erectile dysfunction treatment will go on to have long erectile dysfunction treatment.

Given that kamagra 100 tablets more than 32 million people in the U.S. Have had erectile dysfunction treatment, it is likely that at least 3 million of them will have long erectile dysfunction treatment. I fear this will likely represent a significant health crisis that will reverberate for years to come.The aftereffects of erectile dysfunction treatment will forever scar some affected individuals, families, and -- due to the large number of people potentially affected and the disabling nature of some of the clinical manifestations of long erectile dysfunction treatment -- will have wide reaching social and economic implications.Preparing for a Long-erectile dysfunction treatment FightThe best way to avoid long erectile dysfunction treatment is to avoid erectile dysfunction treatment through vaccination. We must vaccinate as many people kamagra 100 tablets as possible as fast as possible.

Every sector of society must be engaged in this effort. Civic and community leaders, neighborhood associations, non-profit corporations, corporate America, religious institutions, as well as kamagra 100 tablets federal, state, and local governments. This is an all-hands-on deck situation. We must not fail!.

Governments and health systems must prepare for kamagra 100 tablets the tide of patients in need of multidisciplinary post-erectile dysfunction treatment care. Healthcare leaders must anticipate the needs for post-erectile dysfunction treatment care in their systems, develop capacity, and plan accordingly. Owing to the multifaceted nature of long erectile dysfunction treatment, post-erectile dysfunction treatment clinics should at least include providers able to address kamagra 100 tablets respiratory, cardiometabolic, mental, and neurologic sequelae. The U.K.

National Health Service established 40 clinics for provision of post-erectile dysfunction treatment kamagra 100 tablets care. Several health systems in the U.S. Have already started operating clinics for post-erectile dysfunction treatment patients. The experiences of these systems may serve as a blueprint to inform the establishment of post-erectile dysfunction treatment clinics.We must also recognize that we are still learning about long erectile dysfunction treatment, and our understanding will certainly evolve kamagra 100 tablets over time.

€‚For the podcast kamagra viagra jelly associated her latest blog with this article, please visit https://academic.oup.com/eurheartj/pages/Podcasts. First scienceThe erectile dysfunction treatment kamagra has changed the world and has refocused science, including cardiovascular (CV) research.1 This kamagra not only affects the throat and lungs, but also profoundly impacts the CV system. First of all, male sex, obesity, hypertension,2 diabetes and cardiac conditions at large increased the risk of , possibly related to angiotensin-converting enzyme (ACE) expression,3,4 and of kamagra viagra jelly an unfavourable disease course.

Secondly, erectile dysfunction treatment affects the heart, leading to myocarditis,5,6 myocardial injury,7 scar formation and arrhythmias, and heart block,8 as well as affecting the blood vessels, leading to vascular occlusion due to local thrombus formation or embolism and eventually cardiac death.9 The mechanisms involved are the usual suspects, as outlined in the Viewpoint ‘erectile dysfunction treatment is, in the end, an endothelial disease’, by Peter Libby from the Brigham and Women’s Hospital in Boston, USA and myself. It is well known that the vascular endothelium provides the crucial interface between the circulating blood and kamagra viagra jelly tissues, and displays remarkable properties that normally maintain homeostasis.10 This tightly regulated array of functions includes control of haemostasis, fibrinolysis, inflammation, oxidative stress, vascular permeability, and eventually vasomotion and vascular structure. While these functions participate in the moment to moment regulation of the circulation and coordinate many host defence mechanisms, they can also contribute to disease when their usually homeostatic and defensive functions overreach and turn against the host, as is the case with erectile dysfunction, the kamagra causing the current kamagra (Figure 1).

Figure 1Cytokine storm kamagra viagra jelly. Proinflammatory cytokines such as IL-1 and TNF-α induce each other’s gene expression, unleashing an amplification loop that sustains the cytokine storm. The endothelial cell is a key target of cytokines, as they induce action of a central proinflammatory transcriptional hub, nuclear factor-κB.

IL-1 also cause substantial increases in production by endothelial and other cells of IL-6, the kamagra viagra jelly instigator of the hepatocyte acute phase response. The acute phase reactants include fibrinogen, the precursor of clot, and PAI-1, the major inhibitor of our endogenous fibrinolytic system. C-reactive protein, commonly elevated in erectile dysfunction treatment, provides a kamagra viagra jelly readily measured biomarker of inflammatory status.

The alterations in the thrombotic/fibrinolytic balance due to the acute phase response predisposes towards thrombosis in arteries, in the microvasculature including that of organs such as the myocardium and kidney, and in veins, causing deep vein thrombosis and predisposing towards pulmonary embolism. Thus, the very same cytokines that elicit abnormal endothelial functions can unleash the acute phase kamagra viagra jelly response which together with local endothelial dysfunction can conspire to cause the clinical complications of erectile dysfunction treatment. The right side of this diagram aligns therapeutic agents that attack these mechanisms of the cytokine storm and may thus limit its devastating consequences (from Libby P, Lüscher T.

See pages 3038–3044).It produces protean manifestations ranging from head to toe, wreaking seemingly indiscriminate havoc on multiple organ systems including the lungs, heart, brain, kidney, and the vasculature.

This Viewpoint presents the hypothesis that erectile dysfunction treatment, kamagra viagra jelly particularly in the later complicated stages, represents an endothelial disease. Cytokines, protein proinflammatory mediators, are key signals that shift endothelial function from the homeostatic into the defensive mode. The endgame of erectile dysfunction treatment involves a cytokine storm with positive kamagra viagra jelly feedback loops governing cytokine production that overwhelm counter-regulatory mechanisms.

This concept provides a unifying concept of this raging and a framework for rational treatment strategies at a time when we possess an only modest evidence base to guide our therapeutic attempts to confront this novel kamagra.11Surprisingly, emergency unit visits for acute cardiac conditions have declined markedly.12 Several reasons have been suggested. First, patients may have been wary of visiting hospitals during the kamagra.12,13 Secondly, with life on standstill, plaque ruptures and aortic dissections may have become less likely, and, thirdly, the marked reduction in pollution may also have had an influence.14 The first hypothesis is supported by the Fast Track manuscript ‘erectile dysfunction treatment kills at home. The close relationship between the epidemic and the kamagra viagra jelly increase of out-of-hospital cardiac arrests’ by Simone Savastano and colleagues from the Fondazione IRCCS Policlinico San Matteo in Italy.15 They included all consecutive out-of-hospital cardiac arrests (OHCAs) occurring in the Provinces of Lodi, Cremona, Pavia, and Mantova in the 2 months following the first documented case of erectile dysfunction treatment in Lombardia compared with those that occurred in the same time window in 2019.

The cumulative incidence of erectile dysfunction treatment from 21 February to 20 April 2020 was 956/100 000 inhabitants and the cumulative incidence of OHCA was 21/100 000 inhabitants, with a 52% increase as compared with 2019 (Figure 2). A significant correlation was found between the difference kamagra viagra jelly in cumulative incidence of OHCA and the cumulative incidence of erectile dysfunction treatment. Thus, the OHCA excess in 2020 is closely correlated to the erectile dysfunction treatment kamagra.

These findings are important for furthering the understanding of the reduced emergency unit visits and for planning of future kamagras, as outlined in an Editorial by Hanno kamagra viagra jelly Tan from the Academic Medical Center in Amsterdam, the Netherlands.16 Figure 2(A) Over a period of 60 days from 20 February, the cumulative incidence of erectile dysfunction treatment per 100 000 inhabitants in the four provinces and in the overall territory (dotted line) (upper part), and the trend of the difference of OHCA between 2020 and 2019 per 100 000 inhabitants in the four provinces and in the overall territory (dotted line) (bottom part).

See pages 3045–3054).With a prothrombotic state of the endothelium, thrombo-embolism should kamagra viagra jelly increase during the erectile dysfunction treatment kamagra.17 This hypothesis is pursued in a Fast Track entitled ‘Pulmonary embolism in erectile dysfunction treatment patients.

A French multicentre cohort study’ by Ariel Cohen from the Hopital Saint-Antoine in Paris, France.18 In a retrospective multicentric observational study, the authors included consecutive patients hospitalized for erectile dysfunction treatment. Among 1527 patients, 6.7% patients had pulmonary embolism confirmed by computed tomographty pulmonary angiography (CTPA). Intensive care unit (ICU) kamagra viagra jelly transfer and mechanical ventilation were significantly higher in the pulmonary embolism group.

In a univariable analysis, traditional venous thrombo-embolic risk factors and pulmonary lesion extension in chest CT were not associated with pulmonary embolism, while patients under anticoagulation prior to hospitalization or in whom it was introduced during hospitalization had a lower risk of pulmonary embolism, with an odds ratio of 0.37. Male gender, prophylactic or kamagra viagra jelly therapeutic anticoagulation, C-reactive protein, and time from symptom onset to hospitalization were associated with pulmonary embolism. Thus, risk factors for pulmonary embolism in erectile dysfunction treatment do not include traditional thrombo-embolic risk factors, but rather independent clinical and biological findings at admission.

In line with kamagra viagra jelly the concept outlined above, inflammation is a major driver of pulmonary embolism in erectile dysfunction treatment, as further discussed in a thought-provoking Editorial by Adam Torbicki from the Centre of Postgraduate Medical Education in Otwock, Poland.19Inflammation is also a trigger for atrial fibrillation as it changes the electrical properties of the atrial myocardium and eventually favours tissue fibrosis.20 Furthermore, inflammation may trigger tissue factor expression in the atrial endothelium and favour thrombus formation.21 On the other hand, life on standstill may reduce sympathetic drive and hence reduce the likelihood of new-onset atrial fibrillation.22 In their article entitled ‘New-onset atrial fibrillation. Incidence, characteristics, and related events following a national erectile dysfunction treatment lockdown of 5.6 million people’, Anders Holt and colleagues from the Copenhagen University Hospital, Herlev and Gentofte in Hellerup, Denmark resolved this conundrum.23 During 3 weeks of lockdown, weekly incidence rates of new-onset AF were 2.3, 1.8, and 1.5 per 1000 person-years, while during the corresponding weeks in 2019, incidence rates were 3.5, 3.4, and 3.6 per 1000 person-years. Incidence rate ratios comparing the same weeks were 0.66, 0.53, and kamagra viagra jelly 0.41.

Patients diagnosed during lockdown were younger and had lower CHA2DS2-VASc-scores. During the first 3 weeks of lockdown, 7.8% of patients experienced an ischaemic stroke or death within 7 days of new-onset atrial fibrillation compared with 5.6% during the equivalent weeks in 2019, corresponding to an odds ratio of 1.41. Thus, following a national lockdown kamagra viagra jelly in Denmark, new-onset atrial fibrillation declined by 47%, while ischaemic stroke or death within 7 days increased.

These complex findings are put into context in an excellent Editorial by Carina Blomstrom-Lundqvist from the Department of Medical Science in Uppsala, Sweden.24Myocardial injury after non-cardiac surgery or MINS is caused by myocardial ischaemia due to a supply–demand mismatch or thrombus and is associated with an increased risk of mortality and major adverse CV events or MACE.25 In their review ‘Myocardial injury after non-cardiac surgery. Diagnosis and management’ Philip Devereaux and colleagues from McMaster University in Hamilton, Canada note that the diagnostic criteria for MINS include elevated post-operative troponin levels with no evidence of a non-ischaemic aetiology during or within 30 days after non-cardiac surgery, and without ischaemic kamagra viagra jelly features such as chest pain or ECG changes.26 Patients with MINS should receive aspirin and a statin, unless contraindicated, and an NOAC (non-vitamin K antagonist oral anticoagulant) if not at high bleeding risk.

First scienceThe erectile dysfunction treatment kamagra has changed the world and has refocused science, including cardiovascular (CV) research.1 This kamagra not only affects the throat and lungs, but also profoundly impacts the CV system. First of all, male sex, obesity, hypertension,2 diabetes and cardiac conditions at large increased the risk of , possibly related to angiotensin-converting enzyme (ACE) expression,3,4 and of an buy kamagra online usa unfavourable disease course. Secondly, erectile dysfunction treatment affects the heart, leading to myocarditis,5,6 myocardial injury,7 scar formation and arrhythmias, and heart block,8 as well as affecting the blood vessels, leading to vascular occlusion due to local thrombus formation or embolism and eventually cardiac death.9 The mechanisms involved are the usual suspects, as outlined in the Viewpoint ‘erectile dysfunction treatment is, in the end, an endothelial disease’, by Peter Libby from the Brigham and Women’s Hospital in Boston, USA and myself. It is well known that the vascular endothelium provides the crucial interface between the circulating blood and tissues, and displays remarkable properties that normally maintain homeostasis.10 This tightly regulated array of functions includes control of haemostasis, fibrinolysis, inflammation, oxidative stress, vascular permeability, and buy kamagra online usa eventually vasomotion and vascular structure.

While these functions participate in the moment to moment regulation of the circulation and coordinate many host defence mechanisms, they can also contribute to disease when their usually homeostatic and defensive functions overreach and turn against the host, as is the case with erectile dysfunction, the kamagra causing the current kamagra (Figure 1). Figure 1Cytokine buy kamagra online usa storm. Proinflammatory cytokines such as IL-1 and TNF-α induce each other’s gene expression, unleashing an amplification loop that sustains the cytokine storm. The endothelial cell is a key target of cytokines, as they induce action of a central proinflammatory transcriptional hub, nuclear factor-κB. IL-1 also cause substantial increases in production by endothelial and other cells of IL-6, the instigator of the buy kamagra online usa hepatocyte acute phase response.

The acute phase reactants include fibrinogen, the precursor of clot, and PAI-1, the major inhibitor of our endogenous fibrinolytic system. C-reactive protein, commonly elevated in erectile dysfunction treatment, provides a buy kamagra online usa readily measured biomarker of inflammatory status. The alterations in the thrombotic/fibrinolytic balance due to the acute phase response predisposes towards thrombosis in arteries, in the microvasculature including that of organs such as the myocardium and kidney, and in veins, causing deep vein thrombosis and predisposing towards pulmonary embolism. Thus, the very same buy kamagra online usa cytokines that elicit abnormal endothelial functions can unleash the acute phase response which together with local endothelial dysfunction can conspire to cause the clinical complications of erectile dysfunction treatment. The right side of this diagram aligns therapeutic agents that attack these mechanisms of the cytokine storm and may thus limit its devastating consequences (from Libby P, Lüscher T.

erectile dysfunction treatment is, in the end, buy kamagra online usa an endothelial disease. See pages 3038–3044).It produces protean manifestations ranging from head to toe, wreaking seemingly indiscriminate havoc on multiple organ systems including the lungs, heart, brain, kidney, and the vasculature. This Viewpoint presents the hypothesis that erectile dysfunction treatment, particularly in buy kamagra online usa the later complicated stages, represents an endothelial disease. Cytokines, protein proinflammatory mediators, are key signals that shift endothelial function from the homeostatic into the defensive mode. The endgame of erectile dysfunction treatment buy kamagra online usa involves a cytokine storm with positive feedback loops governing cytokine production that overwhelm counter-regulatory mechanisms.

This concept provides a unifying concept of this raging and a framework for rational treatment strategies at a time when we possess an only modest evidence base to guide our therapeutic attempts to confront this novel kamagra.11Surprisingly, emergency unit visits for acute cardiac conditions have declined markedly.12 Several reasons have been suggested. First, patients may have been wary of visiting hospitals during the kamagra.12,13 Secondly, with life on standstill, plaque ruptures and aortic dissections may have become less likely, and, thirdly, the marked reduction in pollution may also have had an influence.14 The first hypothesis is supported by the Fast Track manuscript ‘erectile dysfunction treatment kills at home. The close relationship between the epidemic and the increase of out-of-hospital cardiac arrests’ by Simone Savastano and colleagues from the Fondazione IRCCS Policlinico San Matteo in buy kamagra online usa Italy.15 They included all consecutive out-of-hospital cardiac arrests (OHCAs) occurring in the Provinces of Lodi, Cremona, Pavia, and Mantova in the 2 months following the first documented case of erectile dysfunction treatment in Lombardia compared with those that occurred in the same time window in 2019. The cumulative incidence of erectile dysfunction treatment from 21 February to 20 April 2020 was 956/100 000 inhabitants and the cumulative incidence of OHCA was 21/100 000 inhabitants, with a 52% increase as compared with 2019 (Figure 2). A significant correlation was found between the difference in cumulative incidence of OHCA and the cumulative incidence of buy kamagra online usa erectile dysfunction treatment.

Thus, the OHCA excess in 2020 is closely correlated to the erectile dysfunction treatment kamagra. These findings are important for furthering the understanding of the reduced emergency unit visits and for planning of future kamagras, as outlined in an Editorial by Hanno Tan from the Academic Medical Center in Amsterdam, the Netherlands.16 Figure 2(A) Over a period of 60 days from 20 February, the cumulative incidence of erectile dysfunction treatment per 100 000 inhabitants in the four provinces and in the overall territory (dotted line) (upper part), and the trend of the difference of OHCA between 2020 buy kamagra online usa and 2019 per 100 000 inhabitants in the four provinces and in the overall territory (dotted line) (bottom part).

See pages 3045–3054).With a prothrombotic state of the endothelium, buy kamagra online usa thrombo-embolism should increase during the erectile dysfunction treatment kamagra.17 This hypothesis is pursued in a Fast Track entitled ‘Pulmonary embolism in erectile dysfunction treatment patients. A French multicentre cohort study’ by Ariel Cohen from the Hopital Saint-Antoine in Paris, France.18 In a retrospective multicentric observational study, the authors included consecutive patients hospitalized for erectile dysfunction treatment. Among 1527 patients, 6.7% patients had pulmonary embolism confirmed by computed tomographty pulmonary angiography (CTPA). Intensive care unit (ICU) transfer buy kamagra online usa and mechanical ventilation were significantly higher in the pulmonary embolism group. In a univariable analysis, traditional venous thrombo-embolic risk factors and pulmonary lesion extension in chest CT were not associated with pulmonary embolism, while patients under anticoagulation prior to hospitalization or in whom it was introduced during hospitalization had a lower risk of pulmonary embolism, with an odds ratio of 0.37.

Male gender, prophylactic or therapeutic anticoagulation, C-reactive protein, and time from buy kamagra online usa symptom onset to hospitalization were associated with pulmonary embolism. Thus, risk factors for pulmonary embolism in erectile dysfunction treatment do not include traditional thrombo-embolic risk factors, but rather independent clinical and biological findings at admission. In line with the concept outlined above, inflammation is a major driver of pulmonary embolism in erectile dysfunction treatment, as further discussed in a thought-provoking Editorial by Adam Torbicki from the Centre of Postgraduate Medical Education in Otwock, Poland.19Inflammation is also a trigger for atrial fibrillation as it changes the electrical properties of the atrial myocardium and eventually favours tissue buy kamagra online usa fibrosis.20 Furthermore, inflammation may trigger tissue factor expression in the atrial endothelium and favour thrombus formation.21 On the other hand, life on standstill may reduce sympathetic drive and hence reduce the likelihood of new-onset atrial fibrillation.22 In their article entitled ‘New-onset atrial fibrillation. Incidence, characteristics, and related events following a national erectile dysfunction treatment lockdown of 5.6 million people’, Anders Holt and colleagues from the Copenhagen University Hospital, Herlev and Gentofte in Hellerup, Denmark resolved this conundrum.23 During 3 weeks of lockdown, weekly incidence rates of new-onset AF were 2.3, 1.8, and 1.5 per 1000 person-years, while during the corresponding weeks in 2019, incidence rates were 3.5, 3.4, and 3.6 per 1000 person-years. Incidence rate buy kamagra online usa ratios comparing the same weeks were 0.66, 0.53, and 0.41.

Patients diagnosed during lockdown were younger and had lower CHA2DS2-VASc-scores. During the first 3 weeks of lockdown, 7.8% of patients experienced an ischaemic stroke or death within 7 days of new-onset atrial fibrillation compared with 5.6% during the equivalent weeks in 2019, corresponding to an odds ratio of 1.41. Thus, following a national lockdown in Denmark, new-onset atrial buy kamagra online usa fibrillation declined by 47%, while ischaemic stroke or death within 7 days increased. These complex findings are put into context in an excellent Editorial by Carina Blomstrom-Lundqvist from the Department of Medical Science in Uppsala, Sweden.24Myocardial injury after non-cardiac surgery or MINS is caused by myocardial ischaemia due to a supply–demand mismatch or thrombus and is associated with an increased risk of mortality and major adverse CV events or MACE.25 In their review ‘Myocardial injury after non-cardiac surgery. Diagnosis and management’ Philip Devereaux and colleagues from McMaster University in Hamilton, Canada note that the diagnostic criteria for MINS include elevated post-operative troponin levels with no evidence of a non-ischaemic aetiology during or within 30 days after non-cardiac surgery, and without ischaemic features such as chest pain or ECG changes.26 Patients with MINS should receive aspirin and a statin, unless contraindicated, and an NOAC (non-vitamin K antagonist oral anticoagulant) if not at buy kamagra online usa high bleeding risk.

Cardiac catheterization is only recommended for those with recurrent ischaemia, heart failure, or high risk based on non-invasive imaging. Troponin should be measured for the first few days after surgery in patients ≥65 years or with atherosclerotic buy kamagra online usa disease to avoid missing MINS and the opportunity for secondary prophylactic measures and follow-up.Finally, the issue is complemented by various Discussion Forum contributions on this very timely topic.

Kamagra canada wholesale

We are social epidemiologists kamagra canada wholesale and community kamagra oral jelly for sale in usa advocates focused on addressing social determinants of health inequities. While we appreciate O’Neill et al’s effort to link multiple provincial-level administrative data sets to examine homicide victimisation by immigration status in Ontario, Canada, we have concerns about the framing and interpretation of findings and their potential impact on immigrants and refugees.1FRAMING AND APPROACHWhile O’Neill et al’s data and sample size are strengths, the attention to the context of being an immigrant to Canada, theoretical framework and motivation for examining immigrants in relation to homicide victimisation are not fully developed. O’Neill et al do not acknowledge having done kamagra canada wholesale any community engagement which is critical and ethical2 given the long history of exclusion, exploitation, racism and discrimination, and the current global climate of increasing criminalisation of migrants.

Meaningful community engagement offers important context. Helps shape the research purpose, questions, kamagra canada wholesale approach, interpretation and recommendations. And can reduce the potential for harm.Though criminalisation of migration under security pretexts is an infringement of international law,3 and contradicts evidence that immigration is related to a reduction in crime,4 many high-income countries, including Canada, are framing harmful immigration policy (eg, restricting entry, detaining immigrants) as an urgent need to protect against threats of safety and security,4 5 disproportionately targeting racialised and Muslim immigrants and refugees.

Within this policy context, along with political rhetoric to generate support for it, hate crimes are at record highs in Canada, with approximately 85% of these crimes motivated kamagra canada wholesale by racism and ethnic or religious discrimination.6Not only does this paper fail to consider this context, the statements that immigrant communities are ‘predisposed to violence’ without evidence to support this claim.

We are super kamagra online social buy kamagra online usa epidemiologists and community advocates focused on addressing social determinants of health inequities. While we appreciate O’Neill et al’s effort to link multiple provincial-level administrative data sets to examine homicide victimisation by immigration status in Ontario, Canada, we have concerns about the framing and interpretation of findings and their potential impact on immigrants and refugees.1FRAMING AND APPROACHWhile O’Neill et al’s data and sample size are strengths, the attention to the context of being an immigrant to Canada, theoretical framework and motivation for examining immigrants in relation to homicide victimisation are not fully developed. O’Neill et al do not acknowledge having done any community engagement which is critical and ethical2 buy kamagra online usa given the long history of exclusion, exploitation, racism and discrimination, and the current global climate of increasing criminalisation of migrants. Meaningful community engagement offers important context. Helps shape buy kamagra online usa the research purpose, questions, approach, interpretation and recommendations.

And can reduce the potential for harm.Though criminalisation of migration under security pretexts is an infringement of international law,3 and contradicts evidence that immigration is related to a reduction in crime,4 many high-income countries, including Canada, are framing harmful immigration policy (eg, restricting entry, detaining immigrants) as an urgent need to protect against threats of safety and security,4 5 disproportionately targeting racialised and Muslim immigrants and refugees. Within this policy context, along with political rhetoric to generate support for it, hate crimes are at record highs in Canada, with approximately 85% of these crimes motivated by racism and ethnic or religious discrimination.6Not only buy kamagra online usa does this paper fail to consider this context, the statements that immigrant communities are ‘predisposed to violence’ without evidence to support this claim.

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 like this institutions still differ in the composition of the multidisciplinary teams that provide care for patients who have a DSD.11 14 Several projects have now worked to buy cheap kamagra jelly online uk 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 how cultural and financial aspects and the availability of resources differ significantly between countries and buy cheap kamagra jelly online uk 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 to produce a detailed guideline on diagnostics in DSD.19 This shows that a supranational buy cheap kamagra jelly online uk 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 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 buy cheap kamagra jelly online uk 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 buy cheap kamagra jelly online uk 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 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 buy cheap kamagra jelly online uk 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 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 buy cheap kamagra jelly online uk 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 buy cheap kamagra jelly online uk 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 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, buy cheap kamagra jelly online uk 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 buy cheap kamagra jelly online uk were articles that were not open 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 buy cheap kamagra jelly online uk having obtained 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 their input, the final version was presented to the paediatric and genetic associations buy cheap kamagra jelly online uk 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 buy cheap kamagra jelly online uk discrepancy between the 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 buy cheap kamagra jelly online uk 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 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 in NIPT analysis and buy cheap kamagra jelly online uk 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 the couple to their colleague prenatal specialists working with or in a DSD team buy cheap kamagra jelly online uk. 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 buy cheap kamagra jelly online uk of 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 buy cheap kamagra jelly online uk. 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 buy cheap kamagra jelly online uk 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 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, buy cheap kamagra jelly online uk 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, treatment and prognosis cannot be avoided completely buy cheap kamagra jelly online uk. 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 buy cheap kamagra jelly online uk 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 prenatal buy cheap kamagra jelly online uk 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, buy cheap kamagra jelly online uk 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 is no tight time limit, and buy cheap kamagra jelly online uk 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.

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 buy kamagra online usa 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 projects have now worked to resolve this variability in care. The European buy kamagra online usa 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 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 buy kamagra online usa DSD (expert) centres located in the Netherlands and Flanders (the 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 rare endocrine conditions (EndoERN), in which DSD is embedded, may facilitate the expansion of this kind of collaboration across Europe.This paper highlights key buy kamagra online usa 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 the Dutch-Flemish guideline was buy kamagra online usa 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 communication between the specialists involved buy kamagra online usa. 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 interdisciplinary multicentre group was formed with all members buy kamagra online usa 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 buy kamagra online usa 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 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 buy kamagra online usa broad range of Medical Subject Headings terms (eg, DSD, 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 buy kamagra online usa 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 agreement on remaining points of buy kamagra online usa 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 their input, the final buy kamagra online usa 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 buy kamagra online usa a different reason, for example, due to suspicion of other structural anomalies, reveals a discrepancy between the 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 with increasing frequency is a discrepancy between the genotypic sex revealed by non-invasive prenatal testing (NIPT), which is now available to high-risk buy kamagra online usa 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 buy kamagra online usa 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 buy kamagra online usa 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 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 this buy kamagra online usa technique. The procedure(s) that can be followed, including the risks associated with an amniocentesis.

And the type of information buy kamagra online usa 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 buy kamagra online usa 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 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 buy kamagra online usa 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 buy kamagra online usa of not knowing exactly what the child’s genitalia will look like and uncertainty about the diagnosis, 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 buy kamagra online usa 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 buy kamagra online usa 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 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 buy kamagra online usa 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 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 buy kamagra online usa.

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..
