Walgreens viagra price

By Cara Murez and Robin Foster HealthDay Reporter THURSDAY, walgreens viagra price Jan. 6, 2022 (HealthDay News) -- First, there was Beyond Meat. Next up? walgreens viagra price. Beyond Fried Chicken.

KFC announced Wednesday that it will begin offering a plant-based chicken in some of its meals on walgreens viagra price Jan. 10, from the same company known for its meat-free burgers, Beyond Meat. Beyond Fried Chicken was developed by Beyond Meat exclusively walgreens viagra price for KFC, according to a news release from KFC. It was initially offered in 2019 at one Atlanta restaurant before expanding to three states and now to 4,000 restaurants around the country.

Customers can get their plant-based chicken walgreens viagra price as part of a combo meal or a la carte in six- or 12-piece orders. "The mission from day one was simple -- make the world-famous Kentucky Fried Chicken from plants," Kevin Hochman, president of KFC U.S., said in the release. "And now over walgreens viagra price two years later we can say, 'Mission accomplished.'" Yum Brands owns both KFC and Taco Bell, which is also working with Beyond Meat to create some products for those eateries, according to CBS News. Beyond Meat recently hired two former executives from Tyson Foods, a company known for its chicken.

"We couldn't be prouder to partner with KFC to offer a best-in-class product that not only delivers the delicious experience consumers expect from this iconic chain, but also provides the added benefits of plant-based meat," Ethan Brown, founder and CEO of Beyond Meat, said in the release walgreens viagra price. "We are truly thrilled to make it available to consumers nationwide." There has been an increased demand for plant-derived foods, with major chains including McDonald's and Starbucks partnering with Beyond Meat and competitor Impossible Foods to offer additional options, CBS News reported. On Monday, Chipotle began offering plant-based chorizo for a limited time walgreens viagra price. "It's no longer fringe for a company to be doing this -- it's becoming mainstream, and more are seeing it as a necessity" to offer plant-based options, Sean Cash told the Washington Post.

He's an economist with the Friedman School of Nutrition Science and Policy at Tufts University in Boston. Continued And the trend is not confined to walgreens viagra price restaurants, Cash added. As the viagra pushed consumers to cook and eat at home, more meat alternatives were available in some grocery stores. Also, supply chain issues with traditional meats may have walgreens viagra price led consumers to try alternatives.

Fast food chains are "targeting the still relatively small but rapidly growing segment of the population interested in plant-based alternatives to meat, which is increasingly understood to be potentially harmful to health and the environment," Marion Nestle, a professor emerita of nutrition, food studies and public health at New York University, told the Post. Companies "must think there is a market for plant-based alternatives and want walgreens viagra price to bring people who want these alternatives into their stores," Nestle added. More information The U.S. Department of Agriculture has more information on walgreens viagra price vegetarian-based diets.

Washington Post WebMD News from HealthDay Copyright © 2013-2022 HealthDay. All rights reserved.Jan walgreens viagra price. 6, 2022 -- With the arrival of the Omicron variant, these are not easy days for parents, for kids, or for anyone who is trying to figure out what’s best when it comes to the very simple act of attending school.As we’ve seen, one day your child could be on the school bus heading to school, the next testing positive for erectile dysfunction treatment and needing to quarantine for days. It’s a dizzying time of stress, anxiety, and confusion that is taking its toll.“Everyone is so agitated right now,” says Andrea Bonior, PhD, a licensed clinical psychologist in private practice in Washington, DC, and author of Detox Your Thoughts.There are things we can do to make it easier, she says.

First is to take a pause.“It’s very easy to be reactionary in walgreens viagra price what we do and for things to escalate,” Bonior says.Instead, she says, think through your actions and recognize that the uncertainty surrounding us has everyone at a heightened state of alert. And, while parents are among the most stressed right now, it’s crucial for you to be available to your kids. After all, walgreens viagra price they’ve been navigating 2-plus years of a viagra and may find this overwhelming viagra surge scarier than you realize.To help parents help their kids weather today and the days ahead, WebMD asked Steven Meyers, PhD, a professor and chair of psychology at Roosevelt University in Chicago, for the five things parents need to do -- now:1. Give kids the right informationDepending on how old you child is, tailor a message about the Omicron surge that’s understandable.“Given the uncertainty and misinformation out there, it’s hard for parents to navigate this terrain, so just think about how hard it is on your kids,” Meyers says.Keep the message clear about how the whole family can stay safe and define what acceptable risk means.“For example,” he says, “if you have a family member who is immunocompromised, that risk will look different than if your family is young and healthy.

The threat level will vary, and this is important to keep in mind walgreens viagra price because being erectile dysfunction treatment-positive will have different impacts on people’s lives, depending on everyone’s overall health.”2. Lean into the unknowableInstead of acting like you know it all, explain to your kids that the facts about the Omicron variant are developing as we learn more and more about it.“Parents should explain that science is always changing, and as we learn more, the recommendations and decisions will change, too,” Meyers says.“When we’re stressed, we tend to rely on safe versus unsafe, right versus wrong. But we have to get used to the idea that where we are right walgreens viagra price now with this viagra, the guidance is going to keep changing just as the spread and the risk will keep changing.”3. Discuss what safety means to everyoneIf you child says they don’t want to go to school due to the risk of catching erectile dysfunction treatment, listen to their concerns.“Then calmly explain that you’ve followed treatment guidelines and that it’s important to be as safe as possible, depending on his or her age and when he or she got their treatment and booster,” Meyers says.

€œRemember that each person in your family will have a very individual reaction to a walgreens viagra price situation like this and will have different worries and concerns.”4. Watch for anxiety warning signsAs parents know, kids right now are facing considerable stress and anxiety about the viagra and are fatigued from 2 years of this.“Especially among teens, some will keep their fears to themselves, while others will let them leak out through less productive channels, such as erroneous social media postings, headaches, stomachaches, or an inability to sleep,” Meyers says. €œIt’s key for parents to play close attention to these signs of walgreens viagra price anxiety and keep the lines of communication open.”5. Help your teen rethink FOMOWhen teens see Instagram stories featuring their friends partying and gathering in large groups right now, the fear of missing out -- or FOMO -- is real.As a parent, you can turn FOMO into something pretty amazing, Meyers says.“Emphasize the virtue in being safe,” he says.

€œTry to help your teen find a way to transfer this from a feeling of loss to a feeling of what we walgreens viagra price can gain.”An example, he says, is that following safety protocols means not only that we stay healthy, but we protect those we care about.“We are collectively contributing to health of our community,” he says. €œThat might not sound fun, but it’s very important. Parents need to frame being considerate to others as a genuine strength, not a weak consolation prize.”.

Study Design viagra cvs We used two approaches to estimate the effect of vaccination on the delta variant. First, we used a test-negative case–control design to estimate treatment effectiveness against symptomatic disease caused by the viagra cvs delta variant, as compared with the alpha variant, over the period that the delta variant has been circulating. This approach has been described in detail elsewhere.10 In brief, we compared vaccination status in persons with symptomatic erectile dysfunction treatment with vaccination status in persons who reported symptoms but had a negative test. This approach helps to control for biases related to health-seeking behavior, access to viagra cvs testing, and case ascertainment. For the secondary analysis, the proportion of persons with cases caused by the delta variant relative to the main circulating viagra (the alpha variant) was estimated according to vaccination status.

The underlying assumption was that if the treatment had some efficacy and was equally effective viagra cvs against each variant, a similar proportion of cases with either variant would be expected in unvaccinated persons and in vaccinated persons. Conversely, if the treatment was less effective against the delta variant than against the alpha variant, then the delta variant would be expected to make up a higher proportion of cases occurring more than 3 weeks after vaccination than among unvaccinated persons. Details of this analysis are described in Section S1 in the Supplementary Appendix, available with the full text of this article viagra cvs at NEJM.org. The authors vouch for the accuracy and completeness of the data and for the fidelity of the trial to the protocol. Data Sources Vaccination Status Data on all persons in England who have been vaccinated with erectile dysfunction treatments are available in a national vaccination register (the viagra cvs National Immunisation Management System).

Data regarding vaccinations that had occurred up to May 16, 2021, including the date of receipt of each dose of treatment and the treatment type, were extracted on May 17, 2021. Vaccination status was categorized as receipt of one viagra cvs dose of treatment among persons who had symptom onset occurring 21 days or more after receipt of the first dose up to the day before the second dose was received, as receipt of the second dose among persons who had symptom onset occurring 14 days or more after receipt of the second dose, and as receipt of the first or second dose among persons with symptom onset occurring 21 days or more after the receipt of the first dose (including any period after the receipt of the second dose). erectile dysfunction Testing Polymerase-chain-reaction (PCR) testing for erectile dysfunction in the United Kingdom is undertaken by hospital and public health laboratories, as well as by community testing with the use of drive-through or at-home testing, which is available to anyone with symptoms consistent with erectile dysfunction treatment (high temperature, new continuous cough, or loss or change in sense of smell or taste). Data on all positive PCR tests viagra cvs between October 26, 2020, and May 16, 2021, were extracted. Data on all recorded negative community tests among persons who reported symptoms were also extracted for the test-negative case–control analysis.

Children younger viagra cvs than 16 years of age as of March 21, 2021, were excluded. Data were restricted to persons who had reported symptoms, and only viagra cvs persons who had undergone testing within 10 days after symptom onset were included, in order to account for reduced sensitivity of PCR testing beyond this period.25 Identification of Variant Whole-genome sequencing was used to identify the delta and alpha variants. The proportion of all positive samples that were sequenced increased from approximately 10% in February 2021 to approximately 60% in May 2021.4 Sequencing is undertaken at a network of laboratories, including the Wellcome Sanger Institute, where a high proportion of samples has been tested, and whole-genome sequences are assigned to Public Health England definitions of variants on the basis of mutations.26 Spike gene target status on PCR was used as a second approach for identifying each variant. Laboratories used the TaqPath assay (Thermo Fisher Scientific) to test for three viagra cvs gene targets. Spike (S), nucleocapsid (N), and open reading frame 1ab (ORF1ab).

In December 2020, the alpha variant was noted to be associated with negative testing on the S target, so S target–negative status was subsequently used as a proxy for identification of the viagra cvs variant. The alpha variant accounts for between 98% and 100% of S target–negative results in England. Among sequenced samples that tested positive for the S target, the delta variant was in 72.2% of the samples in April 2021 and in 93.0% in May (as of May 12, 2021).4 For the test-negative case–control analysis, only samples that had been tested at laboratories with viagra cvs the use of the TaqPath assay were included. Data Linkage The three data sources described above were linked with the use of the National Health Service number (a unique identifier for each person receiving medical care in the United Kingdom). These data sources were also linked with data on the patient’s date of birth, surname, first name, postal viagra cvs code, and specimen identifiers and sample dates.

Covariates Multiple covariates that may be associated with the likelihood of being offered or accepting a treatment and the risk of exposure to erectile dysfunction treatment or specifically to either of the variants analyzed were also extracted from the National Immunisation Management System and the testing data. These data included age (in 10-year age groups), sex, index of multiple deprivation (a national indication of level of deprivation that is based on small geographic areas of residence,27 assessed in quintiles), race or ethnic group, care home residence status, history of foreign viagra cvs travel (i.e., outside the United Kingdom or Ireland), geographic region, period (calendar week), health and social care worker status, and status of being in a clinically extremely vulnerable group.28 In addition, for the test-negative case–control analysis, history of erectile dysfunction before the start of the vaccination program was included. Persons were considered to have traveled if, at the point of requesting a test, they reported having traveled outside the United Kingdom and Ireland within the preceding 14 days or if they had been tested in a quarantine hotel or while quarantining at home. Postal codes were used to determine the index of multiple deprivation, and unique property-reference numbers were used to identify care homes.29 Statistical Analysis For the test-negative case–control analysis, logistic viagra cvs regression was used to estimate the odds of having a symptomatic, PCR-confirmed case of erectile dysfunction treatment among vaccinated persons as compared with unvaccinated persons (control). Cases were identified as having the delta variant by means of sequencing or if they were S target–positive on the TaqPath PCR assay.

Cases were identified as having viagra cvs the alpha variant by means of sequencing or if they were S target–negative on the TaqPath PCR assay. If a person had tested positive on multiple occasions within a 90-day period (which may represent a single illness episode), only the first positive test was included. A maximum of three randomly chosen negative test results were included for each viagra cvs person. Negative tests in which the sample had been obtained within 3 weeks before a positive result or after a positive result could have been false viagra cvs negatives. Therefore, these were excluded.

Tests that had been administered within 7 days viagra cvs after a previous negative result were also excluded. Persons who had previously tested positive before the analysis period were also excluded in order to estimate treatment effectiveness in fully susceptible persons. All the covariates were included in the model as had been done with previous test-negative case–control analyses, with calendar week included as a factor and viagra cvs without an interaction with region. With regard to S target–positive or –negative status, only persons who had tested positive on the other two PCR gene targets were included. Assignment to the delta variant on the basis of S target status was restricted to the week commencing April 12, 2021, and onward in order to aim for high specificity of S target–positive testing for the delta variant.4 treatment effectiveness for the first dose was estimated among persons with a symptom-onset date that was 21 days or more after receipt of the first dose of treatment, and treatment effects for the viagra cvs second dose were estimated among persons with a symptom-onset date that was 14 days or more after receipt of the second dose.

Comparison was made with unvaccinated persons and with persons who had symptom onset in the period of 4 to 13 days after vaccination in order to help account for differences in underlying risk of . The period from the day of treatment administration (day 0) to day 3 was excluded because reactogenicity to the treatment can cause an increase in testing that biases results, as previously described.10Trial Population Between December 9, 2020, and February 28, 2021, a total of 3732 adolescents were randomly assigned in a 2:1 ratio to receive mRNA-1273 (2489 viagra cvs participants) or placebo (1243 participants) at 26 sites in the United States (Figure 1 and Fig. S1). More than 98% of viagra cvs the participants received a second injection. The most common reasons for not receiving a second injection were withdrawal of consent (10 participants) and loss to follow-up (8 participants).

Table 1 viagra cvs. Table 1. Demographic and Clinical Characteristics in the Safety Population at viagra cvs Baseline. The baseline viagra cvs characteristics were generally balanced in the mRNA-1273 and placebo groups. The mean age of the participants was 14.3 years (74% were 12 to 15 years of age), half of the participants were male (51%), most were White (84%) and most were not Hispanic or Latinx (88%), and 93% had a body-mass index (the weight in kilograms divided by the square of the height in meters) of less than 30 (Table 1).

The median duration of follow-up from randomization to the data snapshot was 83 days, and the median duration from the second viagra cvs injection to the database lock was 53 days. The demographic characteristics of the adolescents were generally similar to those of the young adults in the phase 3 trial (Table S12). A total viagra cvs of 2% of the adults in the phase 3 trial had a positive erectile dysfunction status at baseline as compared with 6% of the adolescents. The demographic characteristics of the per-protocol immunogenicity subpopulations are shown in Table S10. The percentages of adolescents as compared with the young adults years were 8% and 27% for Hispanic or Latinx, 1% and 11% for Black, and 79% and 48% for White non-Hispanic participants, viagra cvs respectively (Table S10).

Safety Figure 2. Figure 2 viagra cvs. Solicited Local and Systemic Adverse Reactions. Shown is the percentage of participants who had a solicited local or systemic adverse reaction within 7 days after the first or second injection (dose 1 or dose 2) of either mRNA-1273 treatment or placebo.Solicited local reactions occurred more frequently in the mRNA-1273 group after the first injection (94.2%) and after the second injection (93.4%) than in viagra cvs the placebo group (36.8% and 32.6%, respectively). In the mRNA-1273 group, the most common solicited local reaction was injection-site pain after the first injection (93.1%.

Grade 3, 5.4%) and second injection (92.4% viagra cvs. Grade 3, 5.1%). In the placebo group, injection-site pain was reported viagra cvs in 34.8% of the participants after the first injection and in 30.3% after the second injection. Grade 3 local adverse reactions in the mRNA-1273 group occurred in 6.8% of the participants after the first injection and in 8.9% after the second injection (Figure 2 and Table S2). In the mRNA-1273 group, systemic adverse reactions were reported in 68.5% of the participants after the first injection and in 86.1% viagra cvs after the second injection.

Grade 3 events were reported in 4.4% and viagra cvs 13.7%, respectively. The most common systemic reactions were fatigue, headache, myalgia, and chills. Headache was reported in 44.6% of the participants viagra cvs in the mRNA-1273 group after the first injection and in 70.2% after the second injection, as compared with 38.5% and 30.2%, respectively, in the placebo group. Fatigue was reported in 47.9% of the participants in the mRNA-1273 group after the first injection and in 67.8% after the second injection, as compared with 36.6% and 28.9%, respectively, in the placebo group. After the second injection, among the mRNA-1273 recipients viagra cvs with available data, grade 3 fever occurred in 46 of 2477 participants (1.9%) and grade 4 fever occurred in 1 of 2477 participants (<0.1%) (Figure 2).

Solicited local or systemic reactions generally persisted for a mean of approximately 4 days (Table S4). Incidences of local reactions that persisted beyond 7 days were numerically higher in the mRNA-1273 group than in the placebo viagra cvs group and were also higher after the first injection (6.4%) than after the second injection (1.6%) in the mRNA-1273 group (Table S5). These results were primarily attributed to axillary swelling or tenderness. The local reactions with onset after day 7 after any injection occurred in 1.3% of mRNA-1273 recipients (erythema in 0.7%, swelling in 0.4%, and axillary swelling or tenderness in viagra cvs 0.4%) (Table S13). The incidences of solicited systemic reactions that persisted beyond 7 days were similar in the mRNA-1273 group (3.1%) and the placebo group (2.6%).

Those with onset after day 7 viagra cvs after any injection occurred in 0.7% and 0.3%, respectively. Overall, the incidence of solicited adverse reactions was generally similar among participants 12 to 15 years of age and those 16 to 17 years of age (Fig. S4). In the mRNA-1273 group, the incidence of solicited local or systemic adverse reactions was generally similar among adolescent participants and young adults, but the incidence of erythema was higher among adolescents than among young adults (Table S8). Unsolicited adverse events up to 28 days after any injection were more frequent in the mRNA-1273 group (20.5%) than in the placebo group (15.9%) (Table S3).

The most common events in the mRNA-1273 group were injection-site lymphadenopathy (in 4.3%) and headache (in 2.4%). Adverse events that were considered by the investigators to be related to the treatment or placebo within 28 days were reported by 12.6% participants in the mRNA-1273 group and 5.8% in the placebo group. One participant had a medically attended adverse event of grade 2 anaphylaxis to tree nuts on day 21 after the second injection of mRNA-1273 that was considered by the investigators to be unrelated to the treatment. No deaths, MIS-C, or adverse events of special interest occurred. No cases of myocarditis or pericarditis have been reported at the time of this report.

Immunogenicity Table 2. Table 2. Immunogenicity of mRNA-1273 in Adolescents and Young Adults. The primary analysis was based on noninferiority of neutralizing antibody titers in adolescents in the phase 2 trial as compared with young adults in the phase 3 trial. The geometric mean titer ratio for neutralizing antibodies in adolescents relative to young adults was 1.08 (95% CI, 0.94 to 1.24) (Table 2).

The levels of antibodies specific for the spike protein are shown in Table S6. In addition, the serologic response was 98.8% among adolescents and 98.6% among young adults, and the absolute difference in serologic response between the adolescents and young adults was 0.2 percentage points (95% CI, −1.8 to 2.4). Therefore, the criteria for noninferiority were met for both primary objectives. Efficacy Figure 3. Figure 3.

Secondary Analyses of Efficacy. treatment efficacy was calculated as 1 minus the ratio of the incidence of erectile dysfunction per 1000 person-years (mRNA-1273 vs. Placebo). The primary definition of erectile dysfunction treatment was at least two systemic symptoms or at least one respiratory symptom plus at least one nasopharyngeal swab, nasal swab, or saliva sample that was positive for erectile dysfunction by RT-PCR. The secondary case definition of erectile dysfunction treatment was at least one systemic or respiratory symptom plus a swab that was positive for erectile dysfunction by RT-PCR.

The category of erectile dysfunction (regardless of symptoms) was defined as a combination of postbaseline symptomatic erectile dysfunction treatment and asymptomatic erectile dysfunction in participants with a negative erectile dysfunction status at baseline. Asymptomatic erectile dysfunction was defined as the absence of symptoms and s detected by a postbaseline positive RT-PCR or serologic test in participants with a negative erectile dysfunction status at baseline. The per-protocol (PP) population consisted of all participants who had received at least one injection of mRNA-1273 or placebo and received planned injections of mRNA-1273 or placebo, complied with the timing of the second injection, had no immunologic and virologic evidence of previous erectile dysfunction treatment at baseline, and had no major protocol deviations. This population included 1042 participants in the placebo group and 2139 participants in the mRNA-1273 group. The modified intention-to-treat population with the exclusion of those who had received the incorrect injection (mITT1) consisted of all participants who had no serologic or virologic evidence of previous erectile dysfunction before the first injection of mRNA-1273 or placebo (both a negative RT-PCR test for erectile dysfunction and a negative serologic test based on binding antibodies specific to erectile dysfunction nucleocapsid at baseline.

This population included 1073 participants in the placebo group and 2163 participants in the mRNA-1273 group. NE denotes not estimated.The treatment efficacy of mRNA-1273 14 days after the second injection was difficult to assess precisely because of the low incidence of erectile dysfunction treatment in the trial population (four cases in the placebo group and no cases in the mRNA-1273 group) (Figure 3 and Table S7). The treatment efficacy of mRNA-1273 according to the less stringent CDC definition of erectile dysfunction treatment with an onset of 14 days after the second injection was 93.3% (95% CI, 47.9 to 99.9) in the per-protocol population and 92.7% (95% CI, 67.8 to 99.2) for cases with an onset of 14 days after the first injection in the mITT1 population (Figure 3 and Fig. S2). For the secondary objectives of prevention of erectile dysfunction with an onset of 14 days after the second injection (in the per-protocol population) and 14 days after the first injection (in the mITT1 population), the treatment efficacy estimates for mRNA-1273 were 55.7% (95% CI, 16.8 to 76.4) and 69.8% (95% CI, 49.9 to 82.1), respectively (Figure 3).

The treatment efficacy of mRNA-1273 was 39.2% (95% CI, −24.7 to 69.7) for asymptomatic with an onset of 14 days after the second injection (per-protocol population) and 59.5% (95% CI, 28.4 to 77.3) with an onset of 14 days after the first injection (mITT1 population) (Figure 3). The breakdown of asymptomatic cases starting 14 days after the first dose (mITT1 population) were 14 cases in the mRNA-1273 group and 20 in the placebo group according to RT-PCR results and 15 cases in each group according to serologic results against nucleocapsid (Table S11). The person-years of follow-up were 513 to 522 (6156 to 6264 person-months) in the mRNA-1273 group and 238 to 248 (2856 to 2976 person-months) in the placebo group.V-safe Surveillance. Local and Systemic Reactogenicity in Pregnant Persons Table 1. Table 1.

Characteristics of Persons Who Identified as Pregnant in the V-safe Surveillance System and Received an mRNA erectile dysfunction treatment. Table 2. Table 2. Frequency of Local and Systemic Reactions Reported on the Day after mRNA erectile dysfunction treatment Vaccination in Pregnant Persons. From December 14, 2020, to February 28, 2021, a total of 35,691 v-safe participants identified as pregnant.

Age distributions were similar among the participants who received the Pfizer–BioNTech treatment and those who received the Moderna treatment, with the majority of the participants being 25 to 34 years of age (61.9% and 60.6% for each treatment, respectively) and non-Hispanic White (76.2% and 75.4%, respectively). Most participants (85.8% and 87.4%, respectively) reported being pregnant at the time of vaccination (Table 1). Solicited reports of injection-site pain, fatigue, headache, and myalgia were the most frequent local and systemic reactions after either dose for both treatments (Table 2) and were reported more frequently after dose 2 for both treatments. Participant-measured temperature at or above 38°C was reported by less than 1% of the participants on day 1 after dose 1 and by 8.0% after dose 2 for both treatments. Figure 1.

Figure 1. Most Frequent Local and Systemic Reactions Reported in the V-safe Surveillance System on the Day after mRNA erectile dysfunction treatment Vaccination. Shown are solicited reactions in pregnant persons and nonpregnant women 16 to 54 years of age who received a messenger RNA (mRNA) erectile dysfunction disease 2019 (erectile dysfunction treatment) treatment — BNT162b2 (Pfizer–BioNTech) or mRNA-1273 (Moderna) — from December 14, 2020, to February 28, 2021. The percentage of respondents was calculated among those who completed a day 1 survey, with the top events shown of injection-site pain (pain), fatigue or tiredness (fatigue), headache, muscle or body aches (myalgia), chills, and fever or felt feverish (fever).These patterns of reporting, with respect to both most frequently reported solicited reactions and the higher reporting of reactogenicity after dose 2, were similar to patterns observed among nonpregnant women (Figure 1). Small differences in reporting frequency between pregnant persons and nonpregnant women were observed for specific reactions (injection-site pain was reported more frequently among pregnant persons, and other systemic reactions were reported more frequently among nonpregnant women), but the overall reactogenicity profile was similar.

Pregnant persons did not report having severe reactions more frequently than nonpregnant women, except for nausea and vomiting, which were reported slightly more frequently only after dose 2 (Table S3). V-safe Pregnancy Registry. Pregnancy Outcomes and Neonatal Outcomes Table 3. Table 3. Characteristics of V-safe Pregnancy Registry Participants.

As of March 30, 2021, the v-safe pregnancy registry call center attempted to contact 5230 persons who were vaccinated through February 28, 2021, and who identified during a v-safe survey as pregnant at or shortly after erectile dysfunction treatment vaccination. Of these, 912 were unreachable, 86 declined to participate, and 274 did not meet inclusion criteria (e.g., were never pregnant, were pregnant but received vaccination more than 30 days before the last menstrual period, or did not provide enough information to determine eligibility). The registry enrolled 3958 participants with vaccination from December 14, 2020, to February 28, 2021, of whom 3719 (94.0%) identified as health care personnel. Among enrolled participants, most were 25 to 44 years of age (98.8%), non-Hispanic White (79.0%), and, at the time of interview, did not report a erectile dysfunction treatment diagnosis during pregnancy (97.6%) (Table 3). Receipt of a first dose of treatment meeting registry-eligibility criteria was reported by 92 participants (2.3%) during the periconception period, by 1132 (28.6%) in the first trimester of pregnancy, by 1714 (43.3%) in the second trimester, and by 1019 (25.7%) in the third trimester (1 participant was missing information to determine the timing of vaccination) (Table 3).

Among 1040 participants (91.9%) who received a treatment in the first trimester and 1700 (99.2%) who received a treatment in the second trimester, initial data had been collected and follow-up scheduled at designated time points approximately 10 to 12 weeks apart. Limited follow-up calls had been made at the time of this analysis. Table 4. Table 4. Pregnancy Loss and Neonatal Outcomes in Published Studies and V-safe Pregnancy Registry Participants.

Among 827 participants who had a completed pregnancy, the pregnancy resulted in a live birth in 712 (86.1%), in a spontaneous abortion in 104 (12.6%), in stillbirth in 1 (0.1%), and in other outcomes (induced abortion and ectopic pregnancy) in 10 (1.2%). A total of 96 of 104 spontaneous abortions (92.3%) occurred before 13 weeks of gestation (Table 4), and 700 of 712 pregnancies that resulted in a live birth (98.3%) were among persons who received their first eligible treatment dose in the third trimester. Adverse outcomes among 724 live-born infants — including 12 sets of multiple gestation — were preterm birth (60 of 636 among those vaccinated before 37 weeks [9.4%]), small size for gestational age (23 of 724 [3.2%]), and major congenital anomalies (16 of 724 [2.2%]). No neonatal deaths were reported at the time of interview. Among the participants with completed pregnancies who reported congenital anomalies, none had received erectile dysfunction treatment in the first trimester or periconception period, and no specific pattern of congenital anomalies was observed.

Calculated proportions of pregnancy and neonatal outcomes appeared similar to incidences published in the peer-reviewed literature (Table 4). Adverse-Event Findings on the VAERS During the analysis period, the VAERS received and processed 221 reports involving erectile dysfunction treatment vaccination among pregnant persons. 155 (70.1%) involved nonpregnancy-specific adverse events, and 66 (29.9%) involved pregnancy- or neonatal-specific adverse events (Table S4). The most frequently reported pregnancy-related adverse events were spontaneous abortion (46 cases. 37 in the first trimester, 2 in the second trimester, and 7 in which the trimester was unknown or not reported), followed by stillbirth, premature rupture of membranes, and vaginal bleeding, with 3 reports for each.

No congenital anomalies were reported to the VAERS, a requirement under the EUAs.To the Editor. The Centers for Disease Control and Prevention recently reported cases of myocarditis and pericarditis in the United States after erectile dysfunction disease 2019 (erectile dysfunction treatment) messenger RNA (mRNA) vaccination.1 In recently published reports, diagnosis of myocarditis was made with the use of noninvasive imaging and routine laboratory testing.2-5 Here, we report two cases of histologically confirmed myocarditis after erectile dysfunction treatment mRNA vaccination. Figure 1. Figure 1. Histopathological Findings from Endomyocardial Biopsy and Autopsy.

Hematoxylin–eosin stains of heart-tissue specimens obtained by means of endomyocardial biopsy in patient 1 (Panel A) and autopsy in patient 2 (Panel B) showed myocarditis in both patients, with multifocal cardiomyocyte damage (arrows) associated with mixed inflammatory infiation. Scattered eosinophils were noted (arrowheads). The images of the hematoxylin–eosin stains were obtained with 10× eyepieces and 40× or 60× objectives. Additional information is provided in the Supplementary Appendix. RV denotes right ventricle, and LV left ventricle.Patient 1, a 45-year-old woman without a viral prodrome, presented with dyspnea and dizziness 10 days after BNT162b2 vaccination (first dose).

A nasopharyngeal viral panel was negative for severe acute respiratory syndrome erectile dysfunction 2 (erectile dysfunction), influenza A and B, enteroviagraes, and adenoviagra (Table S1 in the Supplementary Appendix, available with the full text of this letter at NEJM.org). A serum polymerase-chain-reaction (PCR) assay and serologic tests showed no evidence of active parvoviagra, enteroviagra, human immunodeficiency viagra, or with erectile dysfunction. At presentation, she had tachycardia. ST-segment depression detected on electrocardiography, which was most prominent in the lateral leads (Fig. S1).

And a troponin I level of 6.14 ng per milliliter (reference range, 0 to 0.30). A transthoracic echocardiogram showed severe global left ventricular systolic dysfunction (ejection fraction, 15 to 20%) and normal left ventricular dimensions. Right heart catheterization revealed elevated right- and left-sided filling pressures and a cardiac index of 1.66 liters per minute per square meter of body-surface area as measured by the Fick method. Coronary angiography revealed no obstructive coronary artery disease. An endomyocardial biopsy specimen showed an inflammatory infiate predominantly composed of T-cells and macrophages, admixed with eosinophils, B cells, and plasma cells (Figure 1A and Figs.

S2 through S4). She received inotropic support, intravenous diuretics, methylprednisolone (1 g daily for 3 days), and, eventually, guideline-directed medical therapy for heart failure (lisinopril, spironolactone, and metoprolol succinate). Seven days after presentation, her ejection fraction was 60%, and she was discharged home. Patient 2, a 42-year-old man, presented with dyspnea and chest pain 2 weeks after mRNA-1273 vaccination (second dose). He did not report a viral prodrome, and a PCR test was negative for erectile dysfunction (Table S1).

He had tachycardia and a fever, and his electrocardiogram showed diffuse ST-segment elevation (Fig. S1). A transthoracic echocardiogram showed global biventricular dysfunction (ejection fraction, 15%), normal ventricular dimensions, and left ventricular hypertrophy. Coronary angiography revealed no coronary artery disease. Cardiogenic shock developed in the patient, and he died 3 days after presentation.

An autopsy revealed biventricular myocarditis (Figure 1B and Figs. S5 and S6). An inflammatory infiate admixed with macrophages, T-cells, eosinophils, and B cells was observed, a finding similar to that in Patient 1. In these two adult cases of histologically confirmed, fulminant myocarditis that had developed within 2 weeks after erectile dysfunction treatment vaccination, a direct causal relationship cannot be definitively established because we did not perform testing for viral genomes or autoantibodies in the tissue specimens. However, no other causes were identified by PCR assay or serologic examination.

Study Design We used two approaches to walgreens viagra price estimate the effect https://leipzigtrails.de/where-can-i-buy-viagra-over-the-counter/ of vaccination on the delta variant. First, we used a test-negative case–control design to estimate treatment effectiveness against symptomatic disease caused by the walgreens viagra price delta variant, as compared with the alpha variant, over the period that the delta variant has been circulating. This approach has been described in detail elsewhere.10 In brief, we compared vaccination status in persons with symptomatic erectile dysfunction treatment with vaccination status in persons who reported symptoms but had a negative test. This approach walgreens viagra price helps to control for biases related to health-seeking behavior, access to testing, and case ascertainment.

For the secondary analysis, the proportion of persons with cases caused by the delta variant relative to the main circulating viagra (the alpha variant) was estimated according to vaccination status. The underlying assumption was that if the treatment walgreens viagra price had some efficacy and was equally effective against each variant, a similar proportion of cases with either variant would be expected in unvaccinated persons and in vaccinated persons. Conversely, if the treatment was less effective against the delta variant than against the alpha variant, then the delta variant would be expected to make up a higher proportion of cases occurring more than 3 weeks after vaccination than among unvaccinated persons. Details of this analysis are described walgreens viagra price in Section S1 in the Supplementary Appendix, available with the full text of this article at NEJM.org.

The authors vouch for the accuracy and completeness of the data and for the fidelity of the trial to the protocol. Data Sources Vaccination Status Data on all persons in England who have been vaccinated with erectile dysfunction treatments are available in a national vaccination register walgreens viagra price (the National Immunisation Management System). Data regarding vaccinations that had occurred up to May 16, 2021, including the date of receipt of each dose of treatment and the treatment type, were extracted on May 17, 2021. Vaccination status was categorized as receipt of one dose walgreens viagra price of treatment among persons who had symptom onset occurring 21 days or more after receipt of the first dose up to the day before the second dose was received, as receipt of the second dose among persons who had symptom onset occurring 14 days or more after receipt of the second dose, and as receipt of the first or second dose among persons with symptom onset occurring 21 days or more after the receipt of the first dose (including any period after the receipt of the second dose).

erectile dysfunction Testing Polymerase-chain-reaction (PCR) testing for erectile dysfunction in the United Kingdom is undertaken by hospital and public health laboratories, as well as by community testing with the use of drive-through or at-home testing, which is available to anyone with symptoms consistent with erectile dysfunction treatment (high temperature, new continuous cough, or loss or change in sense of smell or taste). Data on walgreens viagra price all positive PCR tests between October 26, 2020, and May 16, 2021, were extracted. Data on all recorded negative community tests among persons who reported symptoms were also extracted for the test-negative case–control analysis. Children younger than 16 walgreens viagra price years of age as of March 21, 2021, were excluded.

Data were restricted to persons who walgreens viagra price had reported symptoms, and only persons who had undergone testing within 10 days after symptom onset were included, in order to account for reduced sensitivity of PCR testing beyond this period.25 Identification of Variant Whole-genome sequencing was used to identify the delta and alpha variants. The proportion of all positive samples that were sequenced increased from approximately 10% in February 2021 to approximately 60% in May 2021.4 Sequencing is undertaken at a network of laboratories, including the Wellcome Sanger Institute, where a high proportion of samples has been tested, and whole-genome sequences are assigned to Public Health England definitions of variants on the basis of mutations.26 Spike gene target status on PCR was used as a second approach for identifying each variant. Laboratories used the TaqPath assay (Thermo Fisher Scientific) to test walgreens viagra price for three gene targets. Spike (S), nucleocapsid (N), and open reading frame 1ab (ORF1ab).

In December 2020, the alpha variant was noted to be associated with negative testing on the S target, so S target–negative status was subsequently used as a proxy for identification of walgreens viagra price the variant. The alpha variant accounts for between 98% and 100% of S target–negative results in England. Among sequenced samples that tested positive for the S target, the delta variant was in 72.2% of the samples in April 2021 and in 93.0% in May (as of May 12, 2021).4 For the test-negative case–control analysis, only samples that had been walgreens viagra price tested at laboratories with the use of the TaqPath assay were included. Data Linkage The three data sources described above were linked with the use of the National Health Service number (a unique identifier for each person receiving medical care in the United Kingdom).

These data sources were also linked with data on the patient’s date walgreens viagra price of birth, surname, first name, postal code, and specimen identifiers and sample dates. Covariates Multiple covariates that may be associated with the likelihood of being offered or accepting a treatment and the risk of exposure to erectile dysfunction treatment or specifically to either of the variants analyzed were also extracted from the National Immunisation Management System and the testing data. These data included age (in 10-year age groups), sex, index of multiple deprivation (a national indication of level of deprivation that is based on small geographic areas of residence,27 assessed in quintiles), race or ethnic group, care home residence status, history of foreign travel (i.e., outside the United Kingdom or Ireland), geographic region, period (calendar week), health and social care worker status, and status of being in a clinically extremely vulnerable group.28 In addition, for the test-negative case–control analysis, history of erectile dysfunction before the start walgreens viagra price of the vaccination program was included. Persons were considered to have traveled if, at the point of requesting a test, they reported having traveled outside the United Kingdom and Ireland within the preceding 14 days or if they had been tested in a quarantine hotel or while quarantining at home.

Postal codes were used to determine the index of multiple deprivation, and unique property-reference numbers were used to identify care homes.29 walgreens viagra price Statistical Analysis For the test-negative case–control analysis, logistic regression was used to estimate the odds of having a symptomatic, PCR-confirmed case of erectile dysfunction treatment among vaccinated persons as compared with unvaccinated persons (control). Cases were identified as having the delta variant by means of sequencing or if they were S target–positive on the TaqPath PCR assay. Cases were identified as having the alpha variant by means of sequencing or if walgreens viagra price they were S target–negative on the TaqPath PCR assay. If a person had tested positive on multiple occasions within a 90-day period (which may represent a single illness episode), only the first positive test was included.

A maximum of three randomly chosen negative test results were included walgreens viagra price for each person. Negative tests in which the sample had been obtained within 3 weeks before a positive result or after a positive result could have been false negatives walgreens viagra price. Therefore, these were excluded. Tests that had been administered within 7 days after a previous negative result were walgreens viagra price also excluded.

Persons who had previously tested positive before the analysis period were also excluded in order to estimate treatment effectiveness in fully susceptible persons. All the covariates were included in the model as had been done with previous test-negative case–control analyses, walgreens viagra price with calendar week included as a factor and without an interaction with region. With regard to S target–positive or –negative status, only persons who had tested positive on the other two PCR gene targets were included. Assignment to the delta variant on the basis of S target status was restricted to the week commencing April 12, 2021, and onward in order to aim for walgreens viagra price high specificity of S target–positive testing for the delta variant.4 treatment effectiveness for the first dose was estimated among persons with a symptom-onset date that was 21 days or more after receipt of the first dose of treatment, and treatment effects for the second dose were estimated among persons with a symptom-onset date that was 14 days or more after receipt of the second dose.

Comparison was made with unvaccinated persons and with persons who had symptom onset in the period of 4 to 13 days after vaccination in order to help account for differences in underlying risk of . The period from the day of treatment administration (day 0) to day 3 was excluded because reactogenicity to the treatment can cause an increase in testing that biases results, as previously described.10Trial Population Between December 9, 2020, walgreens viagra price and February 28, 2021, a total of 3732 adolescents were randomly assigned in a 2:1 ratio to receive mRNA-1273 (2489 participants) or placebo (1243 participants) at 26 sites in the United States (Figure 1 and Fig. S1). More than 98% of the participants received walgreens viagra price a second injection.

The most common reasons for not receiving a second injection were withdrawal of consent (10 participants) and loss to follow-up (8 participants). Table 1 walgreens viagra price. Table 1. Demographic and walgreens viagra price Clinical Characteristics in the Safety Population at Baseline.

The baseline characteristics were generally walgreens viagra price balanced in the mRNA-1273 and placebo groups. The mean age of the participants was 14.3 years (74% were 12 to 15 years of age), half of the participants were male (51%), most were White (84%) and most were not Hispanic or Latinx (88%), and 93% had a body-mass index (the weight in kilograms divided by the square of the height in meters) of less than 30 (Table 1). The median duration of follow-up from randomization to the data snapshot was 83 days, and the median walgreens viagra price duration from the second injection to the database lock was 53 days. The demographic characteristics of the adolescents were generally similar to those of the young adults in the phase 3 trial (Table S12).

A total of 2% of the adults in the phase 3 trial had a positive erectile dysfunction status at walgreens viagra price baseline as compared with 6% of the adolescents. The demographic characteristics of the per-protocol immunogenicity subpopulations are shown in Table S10. The percentages of adolescents as compared with the young adults years were 8% and 27% for walgreens viagra price Hispanic or Latinx, 1% and 11% for Black, and 79% and 48% for White non-Hispanic participants, respectively (Table S10). Safety Figure 2.

Figure 2 walgreens viagra price. Solicited Local and Systemic Adverse Reactions. Shown is the percentage of participants who had a solicited local or systemic adverse reaction within 7 days after the first or second injection (dose 1 or dose 2) of either mRNA-1273 walgreens viagra price treatment or placebo.Solicited local reactions occurred more frequently in the mRNA-1273 group after the first injection (94.2%) and after the second injection (93.4%) than in the placebo group (36.8% and 32.6%, respectively). In the mRNA-1273 group, the most common solicited local reaction was injection-site pain after the first injection (93.1%.

Grade 3, walgreens viagra price 5.4%) and second injection (92.4%. Grade 3, 5.1%). In the placebo group, injection-site pain was reported in 34.8% walgreens viagra price of the participants after the first injection and in 30.3% after the second injection. Grade 3 local adverse reactions in the mRNA-1273 group occurred in 6.8% of the participants after the first injection and in 8.9% after the second injection (Figure 2 and Table S2).

In the mRNA-1273 group, systemic adverse reactions were reported in 68.5% of the participants after the first injection and in 86.1% after the second injection walgreens viagra price. Grade 3 walgreens viagra price events were reported in 4.4% and 13.7%, respectively. The most common systemic reactions were fatigue, headache, myalgia, and chills. Headache was reported in 44.6% of the participants in the mRNA-1273 walgreens viagra price group after the first injection and in 70.2% after the second injection, as compared with 38.5% and 30.2%, respectively, in the placebo group.

Fatigue was reported in 47.9% of the participants in the mRNA-1273 group after the first injection and in 67.8% after the second injection, as compared with 36.6% and 28.9%, respectively, in the placebo group. After the second injection, among walgreens viagra price the mRNA-1273 recipients with available data, grade 3 fever occurred in 46 of 2477 participants (1.9%) and grade 4 fever occurred in 1 of 2477 participants (<0.1%) (Figure 2). Solicited local or systemic reactions generally persisted for a mean of approximately 4 days (Table S4). Incidences of walgreens viagra price local reactions that persisted beyond 7 days were numerically higher in the mRNA-1273 group than in the placebo group and were also higher after the first injection (6.4%) than after the second injection (1.6%) in the mRNA-1273 group (Table S5).

These results were primarily attributed to axillary swelling or tenderness. The local reactions with walgreens viagra price onset after day 7 after any injection occurred in 1.3% of mRNA-1273 recipients (erythema in 0.7%, swelling in 0.4%, and axillary swelling or tenderness in 0.4%) (Table S13). The incidences of solicited systemic reactions that persisted beyond 7 days were similar in the mRNA-1273 group (3.1%) and the placebo group (2.6%). Those with onset after day 7 after any injection walgreens viagra price occurred in 0.7% and 0.3%, respectively.

Overall, the incidence of solicited adverse reactions was generally similar among participants 12 to 15 years of age and those 16 to 17 years of age (Fig. S4). In the mRNA-1273 group, the incidence of solicited local or systemic adverse reactions was generally similar among adolescent participants and young adults, but the incidence of erythema was higher among adolescents than among young adults (Table S8). Unsolicited adverse events up to 28 days after any injection were more frequent in the mRNA-1273 group (20.5%) than in the placebo group (15.9%) (Table S3).

The most common events in the mRNA-1273 group were injection-site lymphadenopathy (in 4.3%) and headache (in 2.4%). Adverse events that were considered by the investigators to be related to the treatment or placebo within 28 days were reported by 12.6% participants in the mRNA-1273 group and 5.8% in the placebo group. One participant had a medically attended adverse event of grade 2 anaphylaxis to tree nuts on day 21 after the second injection of mRNA-1273 that was considered by the investigators to be unrelated to the treatment. No deaths, MIS-C, or adverse events of special interest occurred.

No cases of myocarditis or pericarditis have been reported at the time of this report. Immunogenicity Table 2. Table 2. Immunogenicity of mRNA-1273 in Adolescents and Young Adults.

The primary analysis was based on noninferiority of neutralizing antibody titers in adolescents in the phase 2 trial as compared with young adults in the phase 3 trial. The geometric mean titer ratio for neutralizing antibodies in adolescents relative to young adults was 1.08 (95% CI, 0.94 to 1.24) (Table 2). The levels of antibodies specific for the spike protein are shown in Table S6. In addition, the serologic response was 98.8% among adolescents and 98.6% among young adults, and the absolute difference in serologic response between the adolescents and young adults was 0.2 percentage points (95% CI, −1.8 to 2.4).

Therefore, the criteria for noninferiority were met for both primary objectives. Efficacy Figure 3. Figure 3. Secondary Analyses of Efficacy.

treatment efficacy was calculated as 1 minus the ratio of the incidence of erectile dysfunction per 1000 person-years (mRNA-1273 vs. Placebo). The primary definition of erectile dysfunction treatment was at least two systemic symptoms or at least one respiratory symptom plus at least one nasopharyngeal swab, nasal swab, or saliva sample that was positive for erectile dysfunction by RT-PCR. The secondary case definition of erectile dysfunction treatment was at least one systemic or respiratory symptom plus a swab that was positive for erectile dysfunction by RT-PCR.

The category of erectile dysfunction (regardless of symptoms) was defined as a combination of postbaseline symptomatic erectile dysfunction treatment and asymptomatic erectile dysfunction in participants with a negative erectile dysfunction status at baseline. Asymptomatic erectile dysfunction was defined as the absence of symptoms and s detected by a postbaseline positive RT-PCR or serologic test in participants with a negative erectile dysfunction status at baseline. The per-protocol (PP) population consisted of all participants who had received at least one injection of mRNA-1273 or placebo and received planned injections of mRNA-1273 or placebo, complied with the timing of the second injection, had no immunologic and virologic evidence of previous erectile dysfunction treatment at baseline, and had no major protocol deviations. This population included 1042 participants in the placebo group and 2139 participants in the mRNA-1273 group.

The modified intention-to-treat population with the exclusion of those who had received the incorrect injection (mITT1) consisted of all participants who had no serologic or virologic evidence of previous erectile dysfunction before the first injection of mRNA-1273 or placebo (both a negative RT-PCR test for erectile dysfunction and a negative serologic test based on binding antibodies specific to erectile dysfunction nucleocapsid at baseline. This population included 1073 participants in the placebo group and 2163 participants in the mRNA-1273 group. NE denotes not estimated.The treatment efficacy of mRNA-1273 14 days after the second injection was difficult to assess precisely because of the low incidence of erectile dysfunction treatment in the trial population (four cases in the placebo group and no cases in the mRNA-1273 group) (Figure 3 and Table S7). The treatment efficacy of mRNA-1273 according to the less stringent CDC definition of erectile dysfunction treatment with an onset of 14 days after the second injection was 93.3% (95% CI, 47.9 to 99.9) in the per-protocol population and 92.7% (95% CI, 67.8 to 99.2) for cases with an onset of 14 days after the first injection in the mITT1 population (Figure 3 and Fig.

S2). For the secondary objectives of prevention of erectile dysfunction with an onset of 14 days after the second injection (in the per-protocol population) and 14 days after the first injection (in the mITT1 population), the treatment efficacy estimates for mRNA-1273 were 55.7% (95% CI, 16.8 to 76.4) and 69.8% (95% CI, 49.9 to 82.1), respectively (Figure 3). The treatment efficacy of mRNA-1273 was 39.2% (95% CI, −24.7 to 69.7) for asymptomatic with an onset of 14 days after the second injection (per-protocol population) and 59.5% (95% CI, 28.4 to 77.3) with an onset of 14 days after the first injection (mITT1 population) (Figure 3). The breakdown of asymptomatic cases starting 14 days after the first dose (mITT1 population) were 14 cases in the mRNA-1273 group and 20 in the placebo group according to RT-PCR results and 15 cases in each group according to serologic results against nucleocapsid (Table S11).

The person-years of follow-up were 513 to 522 (6156 to 6264 person-months) in the mRNA-1273 group and 238 to 248 (2856 to 2976 person-months) in the placebo group.V-safe Surveillance. Local and Systemic Reactogenicity in Pregnant Persons Table 1. Table 1. Characteristics of Persons Who Identified as Pregnant in the V-safe Surveillance System and Received an mRNA erectile dysfunction treatment.

Table 2. Table 2. Frequency of Local and Systemic Reactions Reported on the Day after mRNA erectile dysfunction treatment Vaccination in Pregnant Persons. From December 14, 2020, to February 28, 2021, a total of 35,691 v-safe participants identified as pregnant.

Age distributions were similar among the participants who received the Pfizer–BioNTech treatment and those who received the Moderna treatment, with the majority of the participants being 25 to 34 years of age (61.9% and 60.6% for each treatment, respectively) and non-Hispanic White (76.2% and 75.4%, respectively). Most participants (85.8% and 87.4%, respectively) reported being pregnant at the time of vaccination (Table 1). Solicited reports of injection-site pain, fatigue, headache, and myalgia were the most frequent local and systemic reactions after either dose for both treatments (Table 2) and were reported more frequently after dose 2 for both treatments. Participant-measured temperature at or above 38°C was reported by less than 1% of the participants on day 1 after dose 1 and by 8.0% after dose 2 for both treatments.

Figure 1. Figure 1. Most Frequent Local and Systemic Reactions Reported in the V-safe Surveillance System on the Day after mRNA erectile dysfunction treatment Vaccination. Shown are solicited reactions in pregnant persons and nonpregnant women 16 to 54 years of age who received a messenger RNA (mRNA) erectile dysfunction disease 2019 (erectile dysfunction treatment) treatment — BNT162b2 (Pfizer–BioNTech) or mRNA-1273 (Moderna) — from December 14, 2020, to February 28, 2021.

The percentage of respondents was calculated among those who completed a day 1 survey, with the top events shown of injection-site pain (pain), fatigue or tiredness (fatigue), headache, muscle or body aches (myalgia), chills, and fever or felt feverish (fever).These patterns of reporting, with respect to both most frequently reported solicited reactions and the higher reporting of reactogenicity after dose 2, were similar to patterns observed among nonpregnant women (Figure 1). Small differences in reporting frequency between pregnant persons and nonpregnant women were observed for specific reactions (injection-site pain was reported more frequently among pregnant persons, and other systemic reactions were reported more frequently among nonpregnant women), but the overall reactogenicity profile was similar. Pregnant persons did not report having severe reactions more frequently than nonpregnant women, except for nausea and vomiting, which were reported slightly more frequently only after dose 2 (Table S3). V-safe Pregnancy Registry.

Pregnancy Outcomes and Neonatal Outcomes Table 3. Table 3. Characteristics of V-safe Pregnancy Registry Participants. As of March 30, 2021, the v-safe pregnancy registry call center attempted to contact 5230 persons who were vaccinated through February 28, 2021, and who identified during a v-safe survey as pregnant at or shortly after erectile dysfunction treatment vaccination.

Of these, 912 were unreachable, 86 declined to participate, and 274 did not meet inclusion criteria (e.g., were never pregnant, were pregnant but received vaccination more than 30 days before the last menstrual period, or did not provide enough information to determine eligibility). The registry enrolled 3958 participants with vaccination from December 14, 2020, to February 28, 2021, of whom 3719 (94.0%) identified as health care personnel. Among enrolled participants, most were 25 to 44 years of age (98.8%), non-Hispanic White (79.0%), and, at the time of interview, did not report a erectile dysfunction treatment diagnosis during pregnancy (97.6%) (Table 3). Receipt of a first dose of treatment meeting registry-eligibility criteria was reported by 92 participants (2.3%) during the periconception period, by 1132 (28.6%) in the first trimester of pregnancy, by 1714 (43.3%) in the second trimester, and by 1019 (25.7%) in the third trimester (1 participant was missing information to determine the timing of vaccination) (Table 3).

Among 1040 participants (91.9%) who received a treatment in the first trimester and 1700 (99.2%) who received a treatment in the second trimester, initial data had been collected and follow-up scheduled at designated time points approximately 10 to 12 weeks apart. Limited follow-up calls had been made at the time of this analysis. Table 4. Table 4.

Pregnancy Loss and Neonatal Outcomes in Published Studies and V-safe Pregnancy Registry Participants. Among 827 participants who had a completed pregnancy, the pregnancy resulted in a live birth in 712 (86.1%), in a spontaneous abortion in 104 (12.6%), in stillbirth in 1 (0.1%), and in other outcomes (induced abortion and ectopic pregnancy) in 10 (1.2%). A total of 96 of 104 spontaneous abortions (92.3%) occurred before 13 weeks of gestation (Table 4), and 700 of 712 pregnancies that resulted in a live birth (98.3%) were among persons who received their first eligible treatment dose in the third trimester. Adverse outcomes among 724 live-born infants — including 12 sets of multiple gestation — were preterm birth (60 of 636 among those vaccinated before 37 weeks [9.4%]), small size for gestational age (23 of 724 [3.2%]), and major congenital anomalies (16 of 724 [2.2%]).

No neonatal deaths were reported at the time of interview. Among the participants with completed pregnancies who reported congenital anomalies, none had received erectile dysfunction treatment in the first trimester or periconception period, and no specific pattern of congenital anomalies was observed. Calculated proportions of pregnancy and neonatal outcomes appeared similar to incidences published in the peer-reviewed literature (Table 4). Adverse-Event Findings on the VAERS During the analysis period, the VAERS received and processed 221 reports involving erectile dysfunction treatment vaccination among pregnant persons.

155 (70.1%) involved nonpregnancy-specific adverse events, and 66 (29.9%) involved pregnancy- or neonatal-specific adverse events (Table S4). The most frequently reported pregnancy-related adverse events were spontaneous abortion (46 cases. 37 in the first trimester, 2 in the second trimester, and 7 in which the trimester was unknown or not reported), followed by stillbirth, premature rupture of membranes, and vaginal bleeding, with 3 reports for each. No congenital anomalies were reported to the VAERS, a requirement under the EUAs.To the Editor.

The Centers for Disease Control and Prevention recently reported cases of myocarditis and pericarditis in the United States after erectile dysfunction disease 2019 (erectile dysfunction treatment) messenger RNA (mRNA) vaccination.1 In recently published reports, diagnosis of myocarditis was made with the use of noninvasive imaging and routine laboratory testing.2-5 Here, we report two cases of histologically confirmed myocarditis after erectile dysfunction treatment mRNA vaccination. Figure 1. Figure 1. Histopathological Findings from Endomyocardial Biopsy and Autopsy.

Hematoxylin–eosin stains of heart-tissue specimens obtained by means of endomyocardial biopsy in patient 1 (Panel A) and autopsy in patient 2 (Panel B) showed myocarditis in both patients, with multifocal cardiomyocyte damage (arrows) associated with mixed inflammatory infiation. Scattered eosinophils were noted (arrowheads). The images of the hematoxylin–eosin stains were obtained with 10× eyepieces and 40× or 60× objectives. Additional information is provided in the Supplementary Appendix.

RV denotes right ventricle, and LV left ventricle.Patient 1, a 45-year-old woman without a viral prodrome, presented with dyspnea and dizziness 10 days after BNT162b2 vaccination (first dose). A nasopharyngeal viral panel was negative for severe acute respiratory syndrome erectile dysfunction 2 (erectile dysfunction), influenza A and B, enteroviagraes, and adenoviagra (Table S1 in the Supplementary Appendix, available with the full text of this letter at NEJM.org). A serum polymerase-chain-reaction (PCR) assay and serologic tests showed no evidence of active parvoviagra, enteroviagra, human immunodeficiency viagra, or with erectile dysfunction. At presentation, she had tachycardia.

ST-segment depression detected on electrocardiography, which was most prominent in the lateral leads (Fig. S1). And a troponin I level of 6.14 ng per milliliter (reference range, 0 to 0.30). A transthoracic echocardiogram showed severe global left ventricular systolic dysfunction (ejection fraction, 15 to 20%) and normal left ventricular dimensions.

Right heart catheterization revealed elevated right- and left-sided filling pressures and a cardiac index of 1.66 liters per minute per square meter of body-surface area as measured by the Fick method. Coronary angiography revealed no obstructive coronary artery disease. An endomyocardial biopsy specimen showed an inflammatory infiate predominantly composed of T-cells and macrophages, admixed with eosinophils, B cells, and plasma cells (Figure 1A and Figs. S2 through S4).

She received inotropic support, intravenous diuretics, methylprednisolone (1 g daily for 3 days), and, eventually, guideline-directed medical therapy for heart failure (lisinopril, spironolactone, and metoprolol succinate). Seven days after presentation, her ejection fraction was 60%, and she was discharged home. Patient 2, a 42-year-old man, presented with dyspnea and chest pain 2 weeks after mRNA-1273 vaccination (second dose). He did not report a viral prodrome, and a PCR test was negative for erectile dysfunction (Table S1).

He had tachycardia and a fever, and his electrocardiogram showed diffuse ST-segment elevation (Fig. S1). A transthoracic echocardiogram showed global biventricular dysfunction (ejection fraction, 15%), normal ventricular dimensions, and left ventricular hypertrophy. Coronary angiography revealed no coronary artery disease.

Cardiogenic shock developed in the patient, and he died 3 days after presentation. An autopsy revealed biventricular myocarditis (Figure 1B and Figs. S5 and S6). An inflammatory infiate admixed with macrophages, T-cells, eosinophils, and B cells was observed, a finding similar to that in Patient 1.

In these two adult cases of histologically confirmed, fulminant myocarditis that had developed within 2 weeks after erectile dysfunction treatment vaccination, a direct causal relationship cannot be definitively established because we did not perform testing for viral genomes or autoantibodies in the tissue specimens. However, no other causes were identified by PCR assay or serologic examination. Amanda K. Verma, M.D.Kory J.

Dear Reader, Thank you Ventolin online for following the can women take viagra Me&MyDoctor blog. I'm writing to let you know we are moving the public health stories authored by Texas physicians, residents, and medical students, and patients to the Texas Medical Association's social media channels. Be sure to follow us on all our social media accounts (Facebook, Twitter, Instagram) as well as Texas Medicine Today can women take viagra to access these stories and more. We look forward to seeing you there.Best, Olivia Suarez Me&My Doctor EditorSravya Reddy, MDPediatric Resident at The University of Texas at Austin Dell Medical SchoolMember, Texas Medical AssociationHow does the erectile dysfunction treatment viagra factor into potentially abusive situations?.

To stop the spread of erectile dysfunction treatment, we have isolated ourselves into small family units to avoid catching and transmitting the viagra. While saving can women take viagra so many from succumbing to a severe illness, socially isolating has unfortunately posed its own problems. Among those is the increased threat of harm from intimate partner violence, which includes physical violence, sexual violence, stalking, or psychological harm by a current or former partner or spouse. Potential child abuse is an increased threat as well.

The impact of this viagra can women take viagra happened so rapidly that society did not have time to think about all the consequences of social isolation before implementing it. Now those consequences are becoming clear.Social isolation due to the viagra is forcing victims to stay home indefinitely with their abusers. Children and adolescents also have been forced to stay at home since many school districts have made education virtual to keep everyone safe from the viagra. Caregivers are also home because they are working remotely or because they are unemployed can women take viagra.

With the increase in the number of erectile dysfunction treatment cases, financial strain due to the economic downturn, and concerns of contracting the viagra and potentially spreading it to family members, these are highly stressful times. Stress leads to an increase in the rate of intimate partner violence. Even those who suffer from it can begin to become abusive to other household members, thus can women take viagra amplifying the abuse in the household. Some abuse may go unrecognized by the victims themselves.

For example, one can women take viagra important and less well-known type of abuse is coercive control. It’s the type of abuse that doesn’t leave a physical mark, but it’s emotional, verbal, and controlling. Victims often know that something is wrong – but can’t quite identify what it is. Coercive control can still lead can women take viagra to violent physical abuse, and murder.

The way in which people report abuse has also been altered by the viagra.People lacking usual in-person contacts (with teachers, co-workers, or doctors) and the fact that some types of coercive abuse are less recognized lead to fewer people reporting that type of abuse. Child abuse often is discovered during pediatricians’ well-child visits, but the viagra has limited those visits. Many teachers, who can women take viagra might also notice signs of abuse, also are not able to see their students on a daily basis. Some abuse victims visit emergency departments (EDs) in normal times, but ED visits are also down due to erectile dysfunction treatment.Local police in China report that intimate partner violence has tripled in the Hubei province.

The United Nations reports it also increased 30% in France as of March 2020 and increased 25% in Argentina. In the can women take viagra U.S. The conversation about increased intimate partner violence during these times has just now started, and we are beginning to gather data. Preliminary analysis shows police reports of intimate partner violence have increased by 18% to 27% across several U.S.

Cities. Individuals affected by addiction have additional stressors and cannot meet with support groups. Children and adolescents who might otherwise use school as a form of escape from addicted caregivers are no longer able to do so. Financial distress can also play a factor.

According to research, the rate of violence among couples with more financial struggles is nearly three and a half times higher than couples with fewer financial concerns.Abuse also can come from siblings. Any child or adolescent with preexisting behavioral issues is more likely to act out due to seclusion, decreased physical activity, or fewer positive distractions. This could increase risk for others in the household, especially in foster home situations. These other residents might be subject to increased sexual and physical abuse with fewer easy ways to report it.

What can we do about this while abiding by the rules of the viagra?. How can physicians help?. Patients who are victims of intimate partner violence are encouraged to reach out to their doctor. A doctor visit may be either in person or virtual due to the safety precautions many doctors’ offices are enforcing due to erectile dysfunction treatment.

During telehealth visits, physicians should always ask standard questions to screen for potential abuse. They can offer information to all patients, regardless of whether they suspect abuse.People could receive more support if we were to expand access to virtual addiction counseling, increase abuse counseling, and launch more campaigns against intimate partner violence. The best solution might involve a multidisciplinary team, including psychiatrists, social workers, child abuse teams and Child Protective Services, and local school boards. Physicians can help in other ways, too.

Doctors can focus on assessing mental health during well-child and acute clinic visits and telehealth visits. A temporary screening tool for behavioral health during the viagra might be beneficial. Governments could consider allocating resources to telepsychiatry. Many paths can be taken to reduce the burden of mental health issues, and this is an ongoing discussion.

How should physicians approach patients who have or may have experienced intimate partner violence?. Victims of domestic assault can always turn to their physician for guidance on next steps. In response, doctors can:Learn about local resources and have those resources available to your patients;Review safety practices, such as deleting internet browsing history or text messages. Saving abuse hotline information under other listings, such as a grocery store or pharmacy listing.

And creating a new, confidential email account for receiving information about resources or communicating with physicians.If the patient discloses abuse, the clinician and patient can establish signals to identify the presence of an abusive partner during telemedicine appointments.To my fellow physicians, I suggest recognizing and talking about the issue with families.Medical professionals take certain steps if they suspect their patient’s injuries are a result of family violence, or if the patient discloses family violence. Physicians will likely screen a patient, document their conversation with the patient, and offer support and inform the patient of the health risks of staying in an abusive environment, such as severe injuries or even death. A doctor’s priority is his or her patient’s safety, regardless of why the victim might feel forced to remain in an abusive environment. While physicians only report child and elderly abuse, they should encourage any abused patient to report her or his own case, while also understanding the complexity of the issue.

Under no circumstance should any form of abuse be tolerated or suffered. Any intimate partner violence should be avoided, and reported if possible and safe. My hope is that with more awareness of this rising public health concern, potential victims can better deal with the threat of abuse during this stressful viagra – and hopefully avoid it..

AbstractIntroduction buy generic 100mg viagra online viagra connect usa. We report a very rare case of familial breast cancer and diffuse gastric cancer, with germline pathogenic variants in both BRCA1 and CDH1 genes. To the best of our knowledge, this is the first report of viagra connect usa such an association.Family description. The proband is a woman diagnosed with breast cancer at the age of 52 years. She requested genetic counselling in 2012, at the age of 91 years, because of a history of breast cancer in her daughter, her sister, her niece and her paternal grandmother and was viagra connect usa therefore concerned about her relatives.

Her sister and maternal aunt also had gastric cancer. She was tested for several genes associated viagra connect usa with hereditary breast cancer.Results. A large deletion of BRCA1 from exons 1 to 7 and two CDH1 pathogenic cis variants were identified.Conclusion. This complex situation is challenging for genetic counselling and management of at-risk viagra connect usa individuals.cancer. Breastcancer.

Gastricclinical geneticsgenetic screening/counsellingmolecular geneticsIntroductionGLI-Kruppel family member 3 (GLI3) encodes for a zinc finger transcription factor which plays a key role in the sonic hedgehog (SHH) signalling pathway essential viagra connect usa in both limb and craniofacial development.1 2 In hand development, SHH is expressed in the zone of polarising activity (ZPA) on the posterior side of the handplate. The ZPA expresses SHH, creating a gradient of SHH from the posterior to the anterior side of the handplate. In the presence of SHH, full length GLI3-protein is produced (GLI3A), whereas absence of SHH viagra connect usa causes cleavage of GLI3 into its repressor form (GLI3R).3 4 Abnormal expression of this SHH/GLI3R gradient can cause both preaxial and postaxial polydactyly.2Concordantly, pathogenic DNA variants in the GLI3 gene are known to cause multiple syndromes with craniofacial and limb involvement, such as. Acrocallosal syndrome5 (OMIM. 200990), Greig viagra connect usa cephalopolysyndactyly syndrome6 (OMIM.

175700) and Pallister-Hall syndrome7 (OMIM. 146510). Also, in non-syndromic polydactyly, such as preaxial polydactyly-type 4 (PPD4, OMIM. 174700),8 pathogenic variants in GLI3 have been described. Out of these diseases, Pallister-Hall syndrome is the most distinct entity, defined by the presence of central polydactyly and hypothalamic hamartoma.9 The other GLI3 syndromes are defined by the presence of preaxial and/or postaxial polydactyly of the hand and feet with or without syndactyly (Greig syndrome, PPD4).

Also, various mild craniofacial features such as hypertelorism and macrocephaly can occur. Pallister-Hall syndrome is caused by truncating variants in the middle third of the GLI3 gene.10–12 The truncation of GLI3 causes an overexpression of GLI3R, which is believed to be the key difference between Pallister-Hall and the GLI3-mediated polydactyly syndromes.9 11 Although multiple attempts have been made, the clinical and genetic distinction between the GLI3-mediated polydactyly syndromes is less evident. This has for example led to the introduction of subGreig and the formulation of an Oro-facial-digital overlap syndrome.10 Other authors, suggested that we should not regard these diseases as separate entities, but as a spectrum of GLI3-mediated polydactyly syndromes.13Although phenotype/genotype correlation of the different syndromes has been cumbersome, clinical and animal studies do provide evidence that distinct regions within the gene, could be related to the individual anomalies contributing to these syndromes. First, case studies show isolated preaxial polydactyly is caused by both truncating and non-truncating variants throughout the GLI3 gene, whereas in isolated postaxial polydactyly cases truncating variants at the C-terminal side of the gene are observed.12 14 These results suggest two different groups of variants for preaxial and postaxial polydactyly. Second, recent animal studies suggest that posterior malformations in GLI3-mediated polydactyly syndromes are likely related to a dosage effect of GLI3R rather than due to the influence of an altered GLI3A expression.15Past attempts for phenotype/genotype correlation in GLI3-mediated polydactyly syndromes have directly related the diagnosed syndrome to the observed genotype.10–12 16 Focusing on individual hand phenotypes, such as preaxial and postaxial polydactyly and syndactyly might be more reliable because it prevents misclassification due to inconsistent use of syndrome definition.

Subsequently, latent class analysis (LCA) provides the possibility to relate a group of observed variables to a set of latent, or unmeasured, parameters and thereby identifying different subgroups in the obtained dataset.17 As a result, LCA allows us to group different phenotypes within the GLI3-mediated polydactyly syndromes and relate the most important predictors of the grouped phenotypes to the observed GLI3 variants.The aim of our study was to further investigate the correlation of the individual phenotypes to the genotypes observed in GLI3-mediated polydactyly syndromes, using LCA. Cases were obtained by both literature review and the inclusion of local clinical cases. Subsequently, we identified two subclasses of limb anomalies that relate to the underlying GLI3 variant. We provide evidence for two different phenotypic and genotypic groups with predominantly preaxial and postaxial hand and feet anomalies, and we specify those cases with a higher risk for corpus callosum anomalies.MethodsLiterature reviewThe Human Gene Mutation Database (HGMD Professional 2019) was reviewed to identify known pathogenic variants in GLI3 and corresponding phenotypes.18 All references were obtained and cases were included when they were diagnosed with either Greig or subGreig syndrome or PPD4.10–12 Pallister-Hall syndrome and acrocallosal syndrome were excluded because both are regarded distinct syndromes and rather defined by the presence of the non-hand anomalies, than the presence of preaxial or postaxial polydactyly.13 19 Isolated preaxial or postaxial polydactyly were excluded for two reasons. The phenotype/genotype correlations are better understood and both anomalies can occur sporadically which could introduce falsely assumed pathogenic GLI3 variants in the analysis.

Additionally, cases were excluded when case-specific phenotypic or genotypic information was not reported or if these two could not be related to each other. Families with a combined phenotypic description, not reducible to individual family members, were included as one case in the analysis.Clinical casesThe Sophia Children’s Hospital Database was reviewed for cases with a GLI3 variant. Within this population, the same inclusion criteria for the phenotype were valid. Relatives of the index patients were also contacted for participation in this study, when they showed comparable hand, foot, or craniofacial malformations or when a GLI3 variant was identified. Phenotypes of the hand, foot and craniofacial anomalies of the patients treated in the Sophia Children's Hospital were collected using patient documentation.

Family members were identified and if possible, clinically verified. Alternatively, family members were contacted to verify their phenotypes. If no verification was possible, cases were excluded.PhenotypesThe phenotypes of both literature cases and local cases were extracted in a similar fashion. The most frequently reported limb and craniofacial phenotypes were dichotomised. The dichotomised hand and foot phenotypes were preaxial polydactyly, postaxial polydactyly and syndactyly.

Broad halluces or thumbs were commonly reported by authors and were dichotomised as a presentation of preaxial polydactyly. The extracted dichotomised craniofacial phenotypes were hypertelorism, macrocephaly and corpus callosum agenesis. All other phenotypes were registered, but not dichotomised.Pathogenic GLI3 variantsAll GLI3 variants were extracted and checked using Alamut Visual V.2.14. If indicated, variants were renamed according to standard Human Genome Variation Society nomenclature.20 Variants were grouped in either missense, frameshift, nonsense or splice site variants. In the group of frameshift variants, a subgroup with possible splice site effect were identified for subgroup analysis when indicated.

Similarly, nonsense variants prone for nonsense mediated decay (NMD) and nonsense variants with experimentally confirmed NMD were identified.21 Deletions of multiple exons, CNVs and translocations were excluded for analysis. A full list of included mutations is available in the online supplementary materials.Supplemental materialThe location of the variant was compared with five known structural domains of the GLI3 gene. (1) repressor domain, (2) zinc finger domain, (3) cleavage site, (4) activator domain, which we defined as a concatenation of the separately identified transactivation zones, the CBP binding domain and the mediator binding domain (MBD) and (5) the MID1 interaction region domain.1 6 22–24 The boundaries of each of the domains were based on available literature (figure 1, exact locations available in the online supplementary materials). The boundaries used by different authors did vary, therefore a consensus was made.In this figure the posterior probability of an anterior phenotype is plotted against the location of the variant, stratified for the type of mutation that was observed. For better overview, only variants with a location effect were displayed.

The full figure, including all variant types, can be found in the online supplementary figure 1. Each mutation is depicted as a dot, the size of the dot represents the number of observations for that variant. If multiple observations were made, the mean posterior odds and IQR are plotted. For the nonsense variants, variants that were predicted to produce nonsense mediated decay, are depicted using a triangle.

Polytomous variable LCA, poLCA V.1.4.1.). We used our LCA to detect the number of phenotypic subgroups in the dataset and subsequently predict a class membership for each case in the dataset based on the posterior probabilities.In order to make a reliable prediction, only phenotypes that were sufficiently reported and/or ruled out were feasible for LCA, limiting the analysis to preaxial polydactyly, postaxial polydactyly and syndactyly of the hands and feet. Only full cases were included. To determine the optimal number of classes, we fitted a series of models ranging from a one-class to a six-class model.

The optimal number of classes was based on the conditional Akaike information criterion (cAIC), the non adjusted and the sample-size adjusted Bayesian information criterion (BIC and aBIC) and the obtained entropy.25 The explorative LCA produces both posterior probabilities per case for both classes and predicted class membership. Using the predicted class membership, the phenotypic features per class were determined in a univariate analysis (χ2, SPSS V.25). Using the posterior probabilities on latent class (LC) membership, a scatter plot was created using the location of the variant on the x-axis and the probability of class membership on the y-axis for each of the types of variants (Tibco Spotfire V.7.14). Using these scatter plots, variants that give similar phenotypes were clustered.Genotype/phenotype correlationBecause an LC has no clinical value, the correlation between genotypes and phenotypes was investigated using the predictor phenotypes and the clustered phenotypes. First, those phenotypes that contribute most to LC membership were identified.

Second those phenotypes were directly related to the different types of variants (missense, nonsense, frameshift, splice site) and their clustered locations. Quantification of the relation was performed using a univariate analysis using a χ2 test. Because of our selection criteria, meaning patients at least have two phenotypes, a multivariate using a logistic regression analysis was used to detect the most significant predictors in the overall phenotype (SPSS V.25). Finally, we explored the relation of the clustered genotypes to the presence of corpus callosum agenesis, a rare malformation in GLI3-mediated polydactyly syndromes which cannot be readily diagnosed without additional imaging.ResultsWe included 251 patients from the literature and 46 local patients,10–12 16 21 26–43 in total 297 patients from 155 different families with 127 different GLI3 variants, 32 of which were large deletions, CNVs or translocations. In six local cases, the exact variant could not be retrieved by status research.The distribution of the most frequently observed phenotypes and variants are presented in table 1.

Other recurring phenotypes included developmental delay (n=22), broad nasal root (n=23), frontal bossing or prominent forehead (n=16) and craniosynostosis (n=13), camptodactyly (n=8) and a broad first interdigital webspace of the foot (n=6).View this table:Table 1 Baseline phenotypes and genotypes of selected populationThe LCA model was fitted using the six defined hand/foot phenotypes. Model fit indices for the LCA are displayed in table 2. Based on the BIC, a two-class model has the best fit for our data. The four-class model does show a gain in entropy, however with a higher BIC and loss of df. Therefore, based on the majority of performance statistics and the interpretability of the model, a two-class model was chosen.

Table 3 displays the distribution of phenotypes and genotypes over the two classes.View this table:Table 2 Model fit indices for the one-class through six-class model evaluated in our LCAView this table:Table 3 Distribution of phenotypes and genotypes in the two latent classes (LC)Table 1 depicts the baseline phenotypes and genotypes in the obtained population. Note incomplete data especially in the cranium phenotypes. In total 259 valid genotypes were present. In total, 289 cases had complete data for all hand and foot phenotypes (preaxial polydactyly, postaxial polydactyly and syndactyly) and thus were available for LCA. Combined, for phenotype/genotype correlation 258 cases were available with complete genotypes and complete hand and foot phenotypes.Table 2 depicts the model fit indices for all models that have been fitted to our data.Table 3 depicts the distribution of phenotypes and genotypes over the two assigned LCs.

Hand and foot phenotypes were used as input for the LCA, thus are all complete cases. Malformation of the cranium and genotypes do have missing cases. Note that for the LCA, full case description was required, resulting in eight cases due to incomplete phenotypes. Out of these eight, one also had a genotype that thus needed to be excluded. Missingness of genotypic data was higher in LC2, mostly due to CNVs (table 1).In 54/60 cases, a missense variant produced a posterior phenotype.

Likewise, splice site variants show the same phenotype in 23/24 cases (table 3). For both frameshift and nonsense variants, this relation is not significant (52 anterior vs 54 posterior and 26 anterior vs 42 posterior, respectively). Therefore, only for nonsense and frameshift variants the location of the variant was plotted against the probability for LC2 membership in figure 1. A full scatterplot of all variants is available in online supplementary figure 1.Figure 1 reveals a pattern for these nonsense and frameshift variants that reveals that variants at the C-terminal of the gene predict anterior phenotypes. When relating the domains of the GLI3 protein to the observed phenotype, we observe that the majority of patients with a nonsense or frameshift variant in the repressor domain, the zinc finger domain or the cleavage site had a high probability of an LC2/anterior phenotype.

This group contains all variants that are either experimentally determined to be subject to NMD (triangle marker in figure 1) or predicted to be subject to NMD (diamond marker in figure 1). Frameshift and nonsense variants in the activator domain result in high probability for an LC1/posterior phenotype. These variants will be further referred to as truncating variants in the activator domain.The univariate relation of the individual phenotypes to these two groups of variants are estimated and presented in table 4. In our multivariate analysis, postaxial polydactyly of the foot and hand are the strongest predictors (Beta. 2.548, p<0001 and Beta.

1.47, p=0.013, respectively) for patients to have a truncating variant in the activator domain. Moreover, the effect sizes of preaxial polydactyly of the hand and feet (Beta. ˆ’0.797, p=0123 and −1.772, p=0.001) reveals that especially postaxial polydactyly of the foot is the dominant predictor for the genetic substrate of the observed anomalies.View this table:Table 4 Univariate and multivariate analysis of the phenotype/genotype correlationTable 4 shows exploration of the individual phenotypes on the genotype, both univariate and multivariate. The multivariate analysis corrects for the presence of multiple phenotypes in the underlying population.Although the craniofacial anomalies could not be included in the LCA, the relation between the observed anomalies and the identified genetic substrates can be studied. The prevalence of hypertelorism was equally distributed over the two groups of variants (47/135 vs 21/47 respectively, p<0.229).

However for corpus callosum agenesis and macrocephaly, there was a higher prevalence in patients with a truncating variant in the activator domain (3/75 vs 11/41, p<0.001. OR. 8.8, p<0.001) and 42/123 vs 24/48, p<0.05). Noteworthy is the fact that 11/14 cases with corpus callosum agenesis in the dataset had a truncating variant in the activator domain.DiscussionIn this report, we present new insights into the correlation between the phenotype and the genotype in patients with GLI3-mediated polydactyly syndromes. We illustrate that there are two LCs of patients, best predicted by postaxial polydactyly of the hand and foot for LC1, and the preaxial polydactyly of the hand and foot and syndactyly of the foot for LC2.

Patients with postaxial phenotypes have a higher risk of having a truncating variant in the activator domain of the GLI3 gene which is also related to a higher risk of corpus callosum agenesis. These results suggest a functional difference between truncating variants on the N-terminal and the C-terminal side of the GLI3 cleavage site.Previous attempts of phenotype to genotype correlation have not yet provided the clinical confirmation of these assumed mechanisms in the pathophysiology of GLI3-mediated polydactyly syndromes. Johnston et al have successfully determined the Pallister-Hall region in which truncating variants produce a Pallister-Hall phenotype rather than Greig syndrome.11 However, in their latest population study, subtypes of both syndromes were included to explain the full spectrum of observed malformations. In 2015, Demurger et al reported the higher incidence of corpus callosum agenesis in the Greig syndrome population with truncating mutations in the activator domain.12 Al-Qattan in his review summarises the concept of a spectrum of anomalies dependent on haplo-insufficiency (through different mechanisms) and repressor overexpression.13 However, he bases this theory mainly on reviewed experimental data. Our report is the first to provide an extensive clinical review of cases that substantiate the phenotypic difference between the two groups that could fit the suggested mechanisms.

We agree with Al-Qattan et al that a variation of anomalies can be observed given any pathogenic variant in the GLI3 gene, but overall two dominant phenotypes are present. A population with predominantly preaxial anomalies and one with postaxial anomalies. The presence of preaxial or postaxial polydactyly and syndactyly is not mutually exclusive for one of these two subclasses. Meaning that preaxial polydactyly can co-occur with postaxial polydactyly. However, truncating mutations in the activator domain produce a postaxial phenotype, as can be derived from the risk in table 4.

The higher risk of corpus callosum agenesis in this population shows that differentiating between a preaxial phenotype and a postaxial phenotype, instead of between the different GLI3-mediated polydactyly syndromes, might be more relevant regarding diagnostics for corpus callosum agenesis.We chose to use LCA as an exploratory tool only in our population for two reasons. First of all, LCA can be useful to identify subgroups, but there is no ‘true’ model or number of subgroups you can detect. The best fitting model can only be estimated based on the available measures and approximates the true subgroups that might be present. Second, LC membership assignment is a statistical procedure based on the posterior probability, with concordant errors of the estimation, rather than a clinical value that can be measured or evaluated. Therefore, we decided to use our LCA only in an exploratory tool, and perform our statistics using the actual phenotypes that predict LC membership and the associated genotypes.

Overall, this method worked well to differentiate the two subgroups present in our dataset. However, outliers were observed. A qualitative analysis of these outliers is available in the online supplementary data.The genetic substrate for the two phenotypic clusters can be discussed based on multiple experiments. Overall, we hypothesise two genetic clusters. One that is due to haploinsufficiency and one that is due to abnormal truncation of the activator.

The hypothesised cluster of variants that produce haploinsufficiency is mainly based on the experimental data that confirms NMD in two variants and the NMD prediction of other nonsense variants in Alamut. For the frameshift variants, it is also likely that the cleavage of the zinc finger domain results in functional haploinsufficiency either because of a lack of signalling domains or similarly due to NMD. Missense variants could cause haploinsufficiency through the suggested mechanism by Krauss et al who have illustrated that missense variants in the MID1 domain hamper the functional interaction with the MID1-α4-PP2A complex, leading to a subcellular location of GLI3.24 The observed missense variants in our study exceed the region to which Krauss et al have limited the MID-1 interaction domain. An alternative theory is suggested by Zhou et al who have shown that missense variants in the MBD can cause deficiency in the signalling of GLI3A, functionally implicating a relative overexpression of GLI3R.22 However, GLI3R overexpression would likely produce a posterior phenotype, as determined by Hill et al in their fixed homo and hemizygous GLI3R models.15 Therefore, our hypothesis is that all included missense variants have a similar pathogenesis which is more likely in concordance with the mechanism introduced by Krauss et al. To our knowledge, no splice site variants have been functionally described in literature.

However, it is noted that the 15 and last exon encompasses the entire activator domain, thus any splice site mutation is by definition located on the 5′ side of the activator. Based on the phenotype, we would suggest that these variants fail to produce a functional protein. We hypothesise that the truncating variants of the activator domain lead to overexpression of GLI3R in SHH rich areas. In normal development, the presence of SHH prevents the processing of full length GLI34 into GLI3R, thus producing the full length activator. In patients with a truncating variant of the activator domain of GLI3, thus these variants likely have the largest effect in SHH rich areas, such as the ZPA located at the posterior side of the hand/footplate.

Moreover, the lack of posterior anomalies in the GLI3∆699/- mouse model (hemizygous fixed repressor model) compared with the GLI3∆699/∆699 mouse model (homozygous fixed repressor model), suggesting a dosage effect of GLI3R to be responsible for posterior hand anomalies.15 These findings are supported by Lewandowski et al, who show that the majority of the target genes in GLI signalling are regulated by GLI3R rather than GLI3A.44 Together, these findings suggest a role for the location and type of variant in GLI3-mediated syndromes.Interestingly, the difference between Pallister-Hall syndrome and GLI3-mediated polydactyly syndromes has also been attributed to the GLI3R overexpression. However, the difference in phenotype observed in the cases with a truncating variant in the activator domain and Pallister-Hall syndrome suggest different functional consequences. When studying figure 1, it is noted that the included truncating variants on the 3′ side of the cleavage site seldomly affect the CBP binding region, which could provide an explanation for the observed differences. This binding region is included in the Pallister-Hall region as defined by Johnston et al and is necessary for the downstream signalling with GLI1.10 11 23 45 Interestingly, recent reports show that pathogenic variants in GLI1 can produce phenotypes concordant with Ellis von Krefeld syndrome, which includes overlapping features with Pallister-Hall syndrome.46 The four truncating variants observed in this study that do affect the CBP but did not result in a Pallister-Hall phenotype are conflicting with this theory. Krauss et al postulate an alternative hypothesis, they state that the MID1-α4-PP2A complex, which is essential for GLI3A signalling, could also be the reason for overlapping features of Opitz syndrome, caused by variants in MID1, and Pallister-Hall syndrome.

Further analysis is required to fully appreciate the functional differences between truncating mutations that cause Pallister-Hall syndrome and those that result in GLI3-mediated polydactyly syndromes.For the clinical evaluation of patients with GLI3-mediated polydactyly syndromes, intracranial anomalies are likely the most important to predict based on the variant. Unfortunately, the presence of corpus callosum agenesis was not routinely investigated or reported thus this feature could not be used as an indicator phenotype for LC membership. Interestingly when using only hand and foot phenotypes, we did notice a higher prevalence of corpus callosum agenesis in patients with posterior phenotypes. The suggested relation between truncating mutations in the activator domain causing these posterior phenotypes and corpus callosum agenesis was statistically confirmed (OR. 8.8, p<0.001).

Functionally this relation could be caused by the GLI3-MED12 interaction at the MBD. Pathogenic DNA variants in MED12 can cause Opitz-Kaveggia syndrome, a syndrome in which presentation includes corpus callosum agenesis, broad halluces and thumbs.47In conclusion, there are two distinct phenotypes within the GLI3-mediated polydactyly population. Patients with more posteriorly and more anteriorly oriented hand anomalies. Furthermore, this difference is related to the observed variant in GLI3. We hypothesise that variants that cause haploinsufficiency produce anterior anomalies of the hand, whereas variants with abnormal truncation of the activator domain have more posterior anomalies.

Furthermore, patients that have a variant that produces abnormal truncation of the activator domain, have a greater risk for corpus callosum agenesis. Thus, we advocate to differentiate preaxial or postaxial oriented GLI3 phenotypes to explain the pathophysiology as well as to get a risk assessment for corpus callosum agenesis.Data availability statementData are available upon reasonable request.Ethics statementsPatient consent for publicationNot required.Ethics approvalThe research protocol was approved by the local ethics board of the Erasmus MC University Medical Center (MEC 2015-679)..

Breastcancer. Gastricclinical geneticsgenetic screening/counsellingmolecular geneticsIntroductionGLI-Kruppel family member 3 (GLI3) encodes for a zinc finger transcription factor which plays a key role walgreens viagra price in the sonic hedgehog (SHH) signalling pathway essential in both limb and craniofacial development.1 2 In hand development, SHH is expressed in the zone of polarising activity (ZPA) on the posterior side of the handplate. The ZPA expresses SHH, creating a gradient of SHH from the posterior to the anterior side of the handplate.

In the presence walgreens viagra price of SHH, full length GLI3-protein is produced (GLI3A), whereas absence of SHH causes cleavage of GLI3 into its repressor form (GLI3R).3 4 Abnormal expression of this SHH/GLI3R gradient can cause both preaxial and postaxial polydactyly.2Concordantly, pathogenic DNA variants in the GLI3 gene are known to cause multiple syndromes with craniofacial and limb involvement, such as. Acrocallosal syndrome5 (OMIM. 200990), Greig cephalopolysyndactyly syndrome6 walgreens viagra price (OMIM.

175700) and Pallister-Hall syndrome7 (OMIM. 146510). Also, in non-syndromic polydactyly, such as preaxial polydactyly-type 4 (PPD4, OMIM.

174700),8 pathogenic variants in GLI3 have been described. Out of these diseases, Pallister-Hall syndrome is the most distinct entity, defined by the presence of central polydactyly and hypothalamic hamartoma.9 The other GLI3 syndromes are defined by the presence of preaxial and/or postaxial polydactyly of the hand and feet with or without syndactyly (Greig syndrome, PPD4). Also, various mild craniofacial features such as hypertelorism and macrocephaly can occur.

Pallister-Hall syndrome is caused by truncating variants in the middle third of the GLI3 gene.10–12 The truncation of GLI3 causes an overexpression of GLI3R, which is believed to be the key difference between Pallister-Hall and the GLI3-mediated polydactyly syndromes.9 11 Although multiple attempts have been made, the clinical and genetic distinction between the GLI3-mediated polydactyly syndromes is less evident. This has for example led to the introduction of subGreig and the formulation of an Oro-facial-digital overlap syndrome.10 Other authors, suggested that we should not regard these diseases as separate entities, but as a spectrum of GLI3-mediated polydactyly syndromes.13Although phenotype/genotype correlation of the different syndromes has been cumbersome, clinical and animal studies do provide evidence that distinct regions within the gene, could be related to the individual anomalies contributing to these syndromes. First, case studies show isolated preaxial polydactyly is caused by both truncating and non-truncating variants throughout the GLI3 gene, whereas in isolated postaxial polydactyly cases truncating variants at the C-terminal side of the gene are observed.12 14 These results suggest two different groups of variants for preaxial and postaxial polydactyly.

Second, recent animal studies suggest that posterior malformations in GLI3-mediated polydactyly syndromes are likely related to a dosage effect of GLI3R rather than due to the influence of an altered GLI3A expression.15Past attempts for phenotype/genotype correlation in GLI3-mediated polydactyly syndromes have directly related the diagnosed syndrome to the observed genotype.10–12 16 Focusing on individual hand phenotypes, such as preaxial and postaxial polydactyly and syndactyly might be more reliable because it prevents misclassification due to inconsistent use of syndrome definition. Subsequently, latent class analysis (LCA) provides the possibility to relate a group of observed variables to a set of latent, or unmeasured, parameters and thereby identifying different subgroups in the obtained dataset.17 As a result, LCA allows us to group different phenotypes within the GLI3-mediated polydactyly syndromes and relate the most important predictors of the grouped phenotypes to the observed GLI3 variants.The aim of our study was to further investigate the correlation of the individual phenotypes to the genotypes observed in GLI3-mediated polydactyly syndromes, using LCA. Cases were obtained by both literature review and the inclusion of local clinical cases.

Subsequently, we identified two subclasses of limb anomalies that relate to the underlying GLI3 variant. We provide evidence for two different phenotypic and genotypic groups with predominantly preaxial and postaxial hand and feet anomalies, and we specify those cases with a higher risk for corpus callosum anomalies.MethodsLiterature reviewThe Human Gene Mutation Database (HGMD Professional 2019) was reviewed to identify known pathogenic variants in GLI3 and corresponding phenotypes.18 All references were obtained and cases were included when they were diagnosed with either Greig or subGreig syndrome or PPD4.10–12 Pallister-Hall syndrome and acrocallosal syndrome were excluded because both are regarded distinct syndromes and rather defined by the presence of the non-hand anomalies, than the presence of preaxial or postaxial polydactyly.13 19 Isolated preaxial or postaxial polydactyly were excluded for two reasons. The phenotype/genotype correlations are better understood and both anomalies can occur sporadically which could introduce falsely assumed pathogenic GLI3 variants in the analysis.

Additionally, cases were excluded when case-specific phenotypic or genotypic information was not reported or if these two could not be related to each other. Families with a combined phenotypic description, not reducible to individual family members, were included as one case in the analysis.Clinical casesThe Sophia Children’s Hospital Database was reviewed for cases with a GLI3 variant. Within this population, the same inclusion criteria for the phenotype were valid.

Relatives of the index patients were also contacted for participation in this study, when they showed comparable hand, foot, or craniofacial malformations or when a GLI3 variant was identified. Phenotypes of the hand, foot and craniofacial anomalies of the patients treated in the Sophia Children's Hospital were collected using patient documentation. Family members were identified and if possible, clinically verified.

Alternatively, family members were contacted to verify their phenotypes. If no verification was possible, cases were excluded.PhenotypesThe phenotypes of both literature cases and local cases were extracted in a similar fashion. The most frequently reported limb and craniofacial phenotypes were dichotomised.

The dichotomised hand and foot phenotypes were preaxial polydactyly, postaxial polydactyly and syndactyly. Broad halluces or thumbs were commonly reported by authors and were dichotomised as a presentation of preaxial polydactyly. The extracted dichotomised craniofacial phenotypes were hypertelorism, macrocephaly and corpus callosum agenesis.

All other phenotypes were registered, but not dichotomised.Pathogenic GLI3 variantsAll GLI3 variants were extracted and checked using Alamut Visual V.2.14. If indicated, variants were renamed according to standard Human Genome Variation Society nomenclature.20 Variants were grouped in either missense, frameshift, nonsense or splice site variants. In the group of frameshift variants, a subgroup with possible splice site effect were identified for subgroup analysis when indicated.

Similarly, nonsense variants prone for nonsense mediated decay (NMD) and nonsense variants with experimentally confirmed NMD were identified.21 Deletions of multiple exons, CNVs and translocations were excluded for analysis. A full list of included mutations is available in the online supplementary materials.Supplemental materialThe location of the variant was compared with five known structural domains of the GLI3 gene. (1) repressor domain, (2) zinc finger domain, (3) cleavage site, (4) activator domain, which we defined as a concatenation of the separately identified transactivation zones, the CBP binding domain and the mediator binding domain (MBD) and (5) the MID1 interaction region domain.1 6 22–24 The boundaries of each of the domains were based on available literature (figure 1, exact locations available in the online supplementary materials).

The boundaries used by different authors did vary, therefore a consensus was made.In this figure the posterior probability of an anterior phenotype is plotted against the location of the variant, stratified for the type of mutation that was observed. For better overview, only variants with a location effect were displayed. The full figure, including all variant types, can be found in the online supplementary figure 1.

Each mutation is depicted as a dot, the size of the dot represents the number of observations for that variant. If multiple observations were made, the mean posterior odds and IQR are plotted.

Polytomous variable LCA, poLCA V.1.4.1.). We used our LCA to detect the number of phenotypic subgroups in the dataset and subsequently predict a class membership for each case in the dataset based on the posterior probabilities.In order to make a reliable prediction, only phenotypes that were sufficiently reported and/or ruled out were feasible for LCA, limiting the analysis to preaxial polydactyly, postaxial polydactyly and syndactyly of the hands and feet.

Only full cases were included. To determine the optimal number of classes, we fitted a series of models ranging from a one-class to a six-class model. The optimal number of classes was based on the conditional Akaike information criterion (cAIC), the non adjusted and the sample-size adjusted Bayesian information criterion (BIC and aBIC) and the obtained entropy.25 The explorative LCA produces both posterior probabilities per case for both classes and predicted class membership.

Using the predicted class membership, the phenotypic features per class were determined in a univariate analysis (χ2, SPSS V.25). Using the posterior probabilities on latent class (LC) membership, a scatter plot was created using the location of the variant on the x-axis and the probability of class membership on the y-axis for each of the types of variants (Tibco Spotfire V.7.14). Using these scatter plots, variants that give similar phenotypes were clustered.Genotype/phenotype correlationBecause an LC has no clinical value, the correlation between genotypes and phenotypes was investigated using the predictor phenotypes and the clustered phenotypes.

First, those phenotypes that contribute most to LC membership were identified. Second those phenotypes were directly related to the different types of variants (missense, nonsense, frameshift, splice site) and their clustered locations. Quantification of the relation was performed using a univariate analysis using a χ2 test.

Because of our selection criteria, meaning patients at least have two phenotypes, a multivariate using a logistic regression analysis was used to detect the most significant predictors in the overall phenotype (SPSS V.25). Finally, we explored the relation of the clustered genotypes to the presence of corpus callosum agenesis, a rare malformation in GLI3-mediated polydactyly syndromes which cannot be readily diagnosed without additional imaging.ResultsWe included 251 patients from the literature and 46 local patients,10–12 16 21 26–43 in total 297 patients from 155 different families with 127 different GLI3 variants, 32 of which were large deletions, CNVs or translocations. In six local cases, the exact variant could not be retrieved by status research.The distribution of the most frequently observed phenotypes and variants are presented in table 1.

Other recurring phenotypes included developmental delay (n=22), broad nasal root (n=23), frontal bossing or prominent forehead (n=16) and craniosynostosis (n=13), camptodactyly (n=8) and a broad first interdigital webspace of the foot (n=6).View this table:Table 1 Baseline phenotypes and genotypes of selected populationThe LCA model was fitted using the six defined hand/foot phenotypes. Model fit indices for the LCA are displayed in table 2. Based on the BIC, a two-class model has the best fit for our data.

The four-class model does show a gain in entropy, however with a higher BIC and buy generic 100mg viagra online loss of df. Therefore, based on the majority of performance statistics and the interpretability of the model, a two-class model was chosen. Table 3 displays the distribution of phenotypes and genotypes over the two classes.View this table:Table 2 Model fit indices for the one-class through six-class model evaluated in our LCAView this table:Table 3 Distribution of phenotypes and genotypes in the two latent classes (LC)Table 1 depicts the baseline phenotypes and genotypes in the obtained population.

Note incomplete data especially in the cranium phenotypes. In total 259 valid genotypes were present. In total, 289 cases had complete data for all hand and foot phenotypes (preaxial polydactyly, postaxial polydactyly and syndactyly) and thus were available for LCA.

Combined, for phenotype/genotype correlation 258 cases were available with complete genotypes and complete hand and foot phenotypes.Table 2 depicts the model fit indices for all models that have been fitted to our data.Table 3 depicts the distribution of phenotypes and genotypes over the two assigned LCs. Hand and foot phenotypes were used as input for the LCA, thus are all complete cases. Malformation of the cranium and genotypes do have missing cases.

Note that for the LCA, full case description was required, resulting in eight cases due to incomplete phenotypes. Out of these eight, one also had a genotype that thus needed to be excluded. Missingness of genotypic data was higher in LC2, mostly due to CNVs (table 1).In 54/60 cases, a missense variant produced a posterior phenotype.

Likewise, splice site variants show the same phenotype in 23/24 cases (table 3). For both frameshift and nonsense variants, this relation is not significant (52 anterior vs 54 posterior and 26 anterior vs 42 posterior, respectively). Therefore, only for nonsense and frameshift variants the location of the variant was plotted against the probability for LC2 membership in figure 1.

A full scatterplot of all variants is available in online supplementary figure 1.Figure 1 reveals a pattern for these nonsense and frameshift variants that reveals that variants at the C-terminal of the gene predict anterior phenotypes. When relating the domains of the GLI3 protein to the observed phenotype, we observe that the majority of patients with a nonsense or frameshift variant in the repressor domain, the zinc finger domain or the cleavage site had a high probability of an LC2/anterior phenotype. This group contains all variants that are either experimentally determined to be subject to NMD (triangle marker in figure 1) or predicted to be subject to NMD (diamond marker in figure 1).

Frameshift and nonsense variants in the activator domain result in high probability for an LC1/posterior phenotype. These variants will be further referred to as truncating variants in the activator domain.The univariate relation of the individual phenotypes to these two groups of variants are estimated and presented in table 4. In our multivariate analysis, postaxial polydactyly of the foot and hand are the strongest predictors (Beta.

2.548, p<0001 and Beta. 1.47, p=0.013, respectively) for patients to have a truncating variant in the activator domain. Moreover, the effect sizes of preaxial polydactyly of the hand and feet (Beta.

ˆ’0.797, p=0123 and −1.772, p=0.001) reveals that especially postaxial polydactyly of the foot is the dominant predictor for the genetic substrate of the observed anomalies.View this table:Table 4 Univariate and multivariate analysis of the phenotype/genotype correlationTable 4 shows exploration of the individual phenotypes on the genotype, both univariate and multivariate. The multivariate analysis corrects for the presence of multiple phenotypes in the underlying population.Although the craniofacial anomalies could not be included in the LCA, the relation between the observed anomalies and the identified genetic substrates can be studied. The prevalence of hypertelorism was equally distributed over the two groups of variants (47/135 vs 21/47 respectively, p<0.229).

However for corpus callosum agenesis and macrocephaly, there was a higher prevalence in patients with a truncating variant in the activator domain (3/75 vs 11/41, p<0.001. OR. 8.8, p<0.001) and 42/123 vs 24/48, p<0.05).

Noteworthy is the fact that 11/14 cases with corpus callosum agenesis in the dataset had a truncating variant in the activator domain.DiscussionIn this report, we present new insights into the correlation between the phenotype and the genotype in patients with GLI3-mediated polydactyly syndromes. We illustrate that there are two LCs of patients, best predicted by postaxial polydactyly of the hand and foot for LC1, and the preaxial polydactyly of the hand and foot and syndactyly of the foot for LC2. Patients with postaxial phenotypes have a higher risk of having a truncating variant in the activator domain of the GLI3 gene which is also related to a higher risk of corpus callosum agenesis.

These results suggest a functional difference between truncating variants on the N-terminal and the C-terminal side of the GLI3 cleavage site.Previous attempts of phenotype to genotype correlation have not yet provided the clinical confirmation of these assumed mechanisms in the pathophysiology of GLI3-mediated polydactyly syndromes. Johnston et al have successfully determined the Pallister-Hall region in which truncating variants produce a Pallister-Hall phenotype rather than Greig syndrome.11 However, in their latest population study, subtypes of both syndromes were included to explain the full spectrum of observed malformations. In 2015, Demurger et al reported the higher incidence of corpus callosum agenesis in the Greig syndrome population with truncating mutations in the activator domain.12 Al-Qattan in his review summarises the concept of a spectrum of anomalies dependent on haplo-insufficiency (through different mechanisms) and repressor overexpression.13 However, he bases this theory mainly on reviewed experimental data.

Our report is the first to provide an extensive clinical review of cases that substantiate the phenotypic difference between the two groups that could fit the suggested mechanisms. We agree with Al-Qattan et al that a variation of anomalies can be observed given any pathogenic variant in the GLI3 gene, but overall two dominant phenotypes are present.

However, truncating mutations in the activator domain produce a postaxial phenotype, as can be derived from the risk in table 4.

The higher risk of corpus callosum agenesis in this population shows that differentiating between a preaxial phenotype and a postaxial phenotype, instead of between the different GLI3-mediated polydactyly syndromes, might be more relevant regarding diagnostics for corpus callosum agenesis.We chose to use LCA as an exploratory tool only in our population for two reasons.

An alternative theory is suggested by Zhou et al who have shown that missense variants in the MBD can cause deficiency in the signalling of GLI3A, functionally implicating a relative overexpression of GLI3R.22 However, GLI3R overexpression would likely produce a posterior phenotype, as determined by Hill et al in their fixed homo and hemizygous GLI3R models.15 Therefore, our hypothesis is that all included missense variants have a similar pathogenesis which is more likely in concordance with the mechanism introduced by Krauss et al. To our knowledge, no splice site variants have been functionally described in literature.

However, it is noted that the 15 and last exon encompasses the entire activator domain, thus any splice site mutation is by definition located on the 5′ side of the activator. Based on the phenotype, we would suggest that these variants fail to produce a functional protein. We hypothesise that the truncating variants of the activator domain lead to overexpression of GLI3R in SHH rich areas.

In normal development, the presence of SHH prevents the processing of full length GLI34 into GLI3R, thus producing the full length activator. In patients with a truncating variant of the activator domain of GLI3, thus these variants likely have the largest effect in SHH rich areas, such as the ZPA located at the posterior side of the hand/footplate. Moreover, the lack of posterior anomalies in the GLI3∆699/- mouse model (hemizygous fixed repressor model) compared with the GLI3∆699/∆699 mouse model (homozygous fixed repressor model), suggesting a dosage effect of GLI3R to be responsible for posterior hand anomalies.15 These findings are supported by Lewandowski et al, who show that the majority of the target genes in GLI signalling are regulated by GLI3R rather than GLI3A.44 Together, these findings suggest a role for the location and type of variant in GLI3-mediated syndromes.Interestingly, the difference between Pallister-Hall syndrome and GLI3-mediated polydactyly syndromes has also been attributed to the GLI3R overexpression.

However, the difference in phenotype observed in the cases with a truncating variant in the activator domain and Pallister-Hall syndrome suggest different functional consequences. When studying figure 1, it is noted that the included truncating variants on the 3′ side of the cleavage site seldomly affect the CBP binding region, which could provide an explanation for the observed differences. This binding region is included in the Pallister-Hall region as defined by Johnston et al and is necessary for the downstream signalling with GLI1.10 11 23 45 Interestingly, recent reports show that pathogenic variants in GLI1 can produce phenotypes concordant with Ellis von Krefeld syndrome, which includes overlapping features with Pallister-Hall syndrome.46 The four truncating variants observed in this study that do affect the CBP but did not result in a Pallister-Hall phenotype are conflicting with this theory.

Krauss et al postulate an alternative hypothesis, they state that the MID1-α4-PP2A complex, which is essential for GLI3A signalling, could also be the reason for overlapping features of Opitz syndrome, caused by variants in MID1, and Pallister-Hall syndrome. Further analysis is required to fully appreciate the functional differences between truncating mutations that cause Pallister-Hall syndrome and those that result in GLI3-mediated polydactyly syndromes.For the clinical evaluation of patients with GLI3-mediated polydactyly syndromes, intracranial anomalies are likely the most important to predict based on the variant. Unfortunately, the presence of corpus callosum agenesis was not routinely investigated or reported thus this feature could not be used as an indicator phenotype for LC membership.

Interestingly when using only hand and foot phenotypes, we did notice a higher prevalence of corpus callosum agenesis in patients with posterior phenotypes. The suggested relation between truncating mutations in the activator domain causing these posterior phenotypes and corpus callosum agenesis was statistically confirmed (OR. 8.8, p<0.001).

Functionally this relation could be caused by the GLI3-MED12 interaction at the MBD. Pathogenic DNA variants in MED12 can cause Opitz-Kaveggia syndrome, a syndrome in which presentation includes corpus callosum agenesis, broad halluces and thumbs.47In conclusion, there are two distinct phenotypes within the GLI3-mediated polydactyly population. Patients with more posteriorly and more anteriorly oriented hand anomalies.

Furthermore, this difference is related to the observed variant in GLI3. We hypothesise that variants that cause haploinsufficiency produce anterior anomalies of the hand, whereas variants with abnormal truncation of the activator domain have more posterior anomalies. Furthermore, patients that have a variant that produces abnormal truncation of the activator domain, have a greater risk for corpus callosum agenesis.

Thus, we advocate to differentiate preaxial or postaxial oriented GLI3 phenotypes to explain the pathophysiology as well as to get a risk assessment for corpus callosum agenesis.Data availability statementData are available upon reasonable request.Ethics statementsPatient consent for publicationNot required.Ethics approvalThe research protocol was approved by the local ethics board of the Erasmus MC University Medical Center (MEC 2015-679)..
