RESUMEN

BACKGROUND: The COVID-19 pandemic continues to spread across the globe and is associated with significant clinical and humanitarian burden. The desire for parenthood has been described to be positively correlated with psychological well-being: An unfulfilled wish for parenthood is associated with impaired mental health, and the wish for parenthood is a predictor for the development of depressive symptoms. While higher rates of anxiety and depression have been reported in individuals with minoritized sexual identities (compared to heterosexual individuals) during the COVID-19 pandemic, the specific impact of the pandemic and its social restriction measures on this population is poorly understood. METHODS: From April to July 2020, we conducted an anonymous cross-sectional survey online among N = 2463 adults living in Germany. We screened for depressive symptoms (Patient Health Questionnaire-4; PHQ-4) and assessed individuals' desire for parenthood during the pandemic, and motives for or against the desire for parenthood (Leipzig questionnaire on motives for having a child, Version 20; LKM-20), with the aim of identifying differences between individuals with minoritized sexual identities and heterosexual individuals. RESULTS: Compared to heterosexual individuals (n = 1304), individuals with minoritized sexual identities (n = 831) indicated higher levels of depressive symptoms. In our study sample the majority of all participants (81.9%) reported no change in the desire for parenthood since the COVID-19 pandemic. CONCLUSION: The findings underline the unmet need for social, psychological and medical support in regard to family-planning and the desire for parenthood during a pandemic. Furthermore, future research should explore COVID-19-related psychological consequences on individuals' desire for parenthood and building a family.

RESUMEN

BACKGROUND: Preliminary research shows a substantial impact of the COVID-19 pandemic on women's sexual health, whereby empirical work on sexual well-being of minoritized sexual identities is still rare. AIM: The objective of this study was to explore sexual health in heterosexual, lesbian and bisexual cis women during the first wave of COVID-19 pandemic in Germany. METHODS: An anonymous nationwide online survey was conducted among cis women during the first nationwide lockdown in Germany from April 20th to July 20th, 2020. The questionnaire was distributed via e-mail, online chats and social-media platforms. OUTCOMES: Demographic variables and self-report measures from the Sexual Behavior Questionnaire (SBQ-G) "before the pandemic" and "since the pandemic" were collected. RESULTS: A total of 1,368 cis women participants were included: heterosexual women (n = 844), lesbian women (n = 293), bisexual women (n = 231). Results indicate overall decrease in frequency of sexual contacts and masturbation during the COVID-19 pandemic. Regarding differences before and during the pandemic lesbian women showed significant changes in sexual arousal whereas heterosexual women showed significant changes in all dimensions except capability to enjoy sexual intercourse. The data of bisexual women showed significant changes in almost all dimensions except for frequency of sexual intercourse and sexual arousal. Results of the multiple regression analysis revealed that being younger than 36 years-old, and being in a relationship as well as being heterosexual (compared with being lesbian) is positively associated with general satisfaction with sexual life during the pandemic. CLINICAL IMPLICATIONS: The findings suggest that during a pandemic sexual and mental health care for (cis) women should be provided and address the specific needs of sexual minority groups. STRENGTHS & LIMITATIONS: This is the first study to describe sexual behavior in heterosexual, lesbian and bisexual women during the COVID-19 pandemic in Germany. Limitations, however, include the fact that the data described were obtained at only one time point so there is a possibility of recall bias, and that the results cannot be generalized because of the underrepresentation of women over age 46. CONCLUSION: This study examined the impact of the COVID-19 pandemic and resulting social constraints on the sexual health of particular groups of lesbian and bisexual women, which may improve preparedness for future public health and policy crises.

RESUMEN

OBJECTIVE: Recent studies revealed intriguing associations between cholecalciferol (D3) and reproductive functions. Seasonal changes of D3 concentrations are well known; however, they are not always considered in the context of reproductive functions. In this study, we analyzed D3 serum concentration in IVF/ICSI patients with respect to seasonal 3-month quartiles and anti-Muellerian hormone (AMH) referring to the impact on Assisted Reproductive Technologies (ART) outcome. MATERIALS AND RESEARCH METHODS: We studied 469 female patients, presenting between 2012 and 2018 for ART treatment in our fertility center. D3 as well as the AMH serum concentrations were measured at the beginning of the follicle stimulation (days 3-5 of menstrual cycles). Results were evaluated with respect to seasonal quartiles and outcome of the ART cycles. RESULTS: D3 concentrations showed significant fluctuations within annual quartiles with a pronounced peak in August-October and a minimum in February-April (26.0 vs. 20.5 mg/dl; p < 0.0001). Similar seasonal dynamics were found for AMH (2.98 vs. 1.78 ng/ml; p = 0.010) and these were associated with significantly shorter stimulation periods during August-October (11.29 vs. 12.12 days; p = 0.042), higher number of fertilized oocytes between August and October (6.23 vs. 4.97; p = 0.05) along with a trend towards higher numbers of cumulus-oocyte complexes. However, no such differences were found for the numbers of MII oocytes or pregnancy rates. CONCLUSION: Our data indicate seasonal 3-month quartile variations of AMH concentrations and characteristics of ART, such as days of ovarian stimulation and number of fertilized oocytes. Highest AMH concentrations were found between August and October and this quartile was associated with highest D3 concentrations.

RESUMEN

BACKGROUND: The important role of vitamin D3 in human health is well recognized. In this study, we measured serum concentrations of vitamin D3, vitamin B12 and B9 (folic acid) in 410 women undergoing in vitro fertilisation (IVF)/intracytoplasmatic sperm injection (ICSI) with dedicated focus on 3-month changes in consideration of patients' BMI. METHODS: Patients were of European origin and did not take any supplementation of D3. In preparing for pregnancy, patients took ≥4 weeks 400 µg folic acid combined with 9 µg vitamin B12 and 150 µg iodide as recommended. RESULTS: We found a significant 3-month quartile change of D3 serum concentrations (p < 0.0001) with maximum levels in autumn and lowest in spring. D3 correlated significantly with B12 (p = 0.035, ρ = 0.102) and folic acid (p < 0.0001, ρ = 0.191). BMIs however showed a negative correlation with B12 (p = 0.031, ρ = -0.105) and folic acid (p = 0.012, ρ = -0.125). CONCLUSIONS: Our results suggest a model in which the sun exposure during summer months enables storage of D3 followed by a slow release as a major factor to maintain D3 levels throughout the year. Finally, our data indicate that B12 and folic acid uptake might be influenced by vitamin D receptor and D3, where D3 and the BMI appear to have an indirect relationship - via B12 and folic acid.

RESUMEN

PURPOSE: The aim of this study was to confirm the associated M2/ANXA5 carrier risk in women with placenta-mediated pregnancy complications (PMPC) and to test their male partners for such association. Further analysis evaluated the influence of maternal vs. paternal M2 alleles on miscarriage. METHODS: Two hundred eighty-eight couples with preeclampsia (PE), intrauterine growth restriction (IUGR), or premature birth (PB) were recruited (n = 96 of each phenotype). The prevalence of the M2 haplotype was compared to two control cohorts. They included a group of women with a history of normal pregnancy without gestational pathology (Munich controls, n = 94) and a random population sample (PopGen controls, n = 533). RESULTS: Significant association of M2 haplotype and pregnancy complications was confirmed for women and for couples, where prevalence was elevated from 15.4 to 23.8% (p < 0.001). Post hoc analyses demonstrated an association for IUGR and PB individually. A strong link between previous miscarriages and M2 carrier status was identified which may explain the predisposition to placental pregnancy complication. M2/ANXA5 appears to be a risk factor for adverse pregnancy outcomes related, but not limited to miscarriages, with similar prevalence in women and their male partners. CONCLUSION: These findings support the proposed physiological function of ANXA5 as an embryonic anticoagulant that appears deficient in contiguous specter of thrombophilia-related pregnancy complications culminating more frequently in miscarriage in a maternal M2 carrier background.

RESUMEN

STUDY QUESTION: Are unexplained recurrent miscarriages associated with abnormal protamine-1 and protamine-2 mRNA levels in spermatozoa? SUMMARY ANSWER: Both protamine-1 and protamine-2 mRNA levels as well as the protamine-1 to protamine-2 mRNA ratio in spermatozoa from men whose female partners experienced two or more consecutive miscarriages were significantly different compared to those from both healthy control men and subfertile couples undergoing IVF/ICSI. WHAT IS KNOWN ALREADY: Aberrant sperm protamine ratios are known to be associated with male-factor infertility. Data from this study suggest that the protamine mRNA ratio may additionally affect early embryo development. STUDY DESIGN, SIZE, DURATION: The study population was recruited from men whose female partners presented with two or more consecutive unexplained miscarriages in a consultation for recurrent pregnancy loss between 2014 and 2016. At the research laboratory of the Urological Clinic of the University Giessen, spermatozoa from cases and controls were subjected to reverse transcription quantitative PCR (RTqPCR) using specific primer pairs for protamine-1 and protamine-2. PARTICIPANTS/MATERIALS, SETTING, METHODS: Protamine-1 and protamine-2 mRNA levels were analysed in semen samples from 25 men whose female partners experienced at least two consecutive idiopathic miscarriages before the 20th week of gestation. The couples were recruited during consultation at the Fertility Center of the LMU Munich, Germany, and at the Clinical Division of Gynecologic Endocrinology and Reproductive Medicine of the Medical University of Vienna, Austria. Results were compared with those from 32 healthy donors (WHO, 2010) recruited at the Department of Urology, Pediatric Urology and Andrology, Giessen, Germany, and 107 men whose partners participated in an IVF/ICSI program at the Fertility Center of the LMU Munich, Germany. MAIN RESULTS AND THE ROLE OF CHANCE: Protamine-1 and protamine-2 mRNA levels as well as the protamine mRNA ratio and all routine semen parameters revealed significant differences between recurrent miscarriage couples and healthy volunteers (P < 0.01). When comparing recurrent miscarriage couples with couples undergoing IVF/ICSI, Ct-values of protamine-1 and protamine-2 mRNAs were significantly higher and the protamine mRNA ratio was significantly lower in RM couples (P < 0.01). When comparing protamine mRNA levels and the protamine mRNA ratio with routine semen parameters, a significant negative correlation was evident between progressive motility and the protamine-2 mRNA level (P = 0.015), as well as between non-progressive motility and the protamine mRNA ratio (P = 0.023). LIMITATIONS REASONS FOR CAUTION: Although our data demonstrate significant abnormalities in RM, larger sample sizes will be needed to confirm our results. Larger sample sizes should also balance the fact that we had to focus mainly on median protamine mRNA levels. Finally, men in the healthy control group were younger in age than those in the case group, which might have introduced some bias, at least concerning the classic semen parameters. Moreover, only protamine mRNA instead of protein levels could be measured. WIDER IMPLICATIONS OF THE FINDINGS: Although the exact mechanism remains to be elucidated, our data suggest that protamine mRNA levels in spermatozoa are not only important for successful fertilization, but also for proper development of the early embryo. STUDY FUNDING/COMPETING INTEREST(S): Grant from the University Clinic Giessen and Marburg (UKGM 29/2015GI). There are no competing interests. TRIAL REGISTRATION NUMBER: N/A.

RESUMEN

PURPOSE: A repeat Pap smear is sometimes necessary after a short time interval or even immediately, when patients seek for a second opinion or due to study participation. Only limited information is available on the possible impact of a short interval between two Pap smears. Most institutions therefore practice a minimum time span of 6-8 weeks before obtaining a second smear since a short interval is commonly believed to be associated with an increase of false negative results in the second smear. METHODS: Two consecutive Pap smears were obtained from 81 women. 41 smears were processed using the conventional technique, whereas liquid-based cytology was used in the remaining 40 women. Smears were independently evaluated by four different cytopathologists. We analyzed the effect of time interval, both processing techniques and inter-observer variance in cytological evaluation. RESULTS: While the result of the second smear shows a tendency towards a more benign outcome (odds ratio (OR) 1.436, 95% CI 0.972-2.121), this difference was not statistically significant (p = 0.07). No significant differences were observed between conservative and liquid-based cytology (OR 1.554, 95% CI 0.659-3.667, p = 0.31). There was considerable inter-observer variability, and the observer was a strong predictor of the cytological result (OR 0.632-5.083, 95% CI 0.355-8.975, p < 0.01). CONCLUSIONS: We document a tendency towards a more benign outcome without statistical significance in the second smear. Inter-observer variability of different cytopathologists is high and should be kept in mind when evaluating cytology results.

RESUMEN

Normal pregnancy is a state of hypercoagulability with diminishing fibrinolytic activity, which is mainly caused by an increase of plasminogen activator inhibitor type 1 (PAI-1). PAI-1 is the main inhibitor of plasminogen activators, including tissue-type plasminogen activator (tPA) and urokinase-type plasminogen activator (uPA). In human placentas, PAI-1 is expressed in extravillous interstitial trophoblasts and vascular trophoblasts. During implantation and placentation, PAI-1 is responsible for inhibiting extra cellular matrix (ECM) degradation, thereby causing an inhibition of trophoblasts invasion. In the present study, we have reviewed the literature of various reproductive diseases where PAI-1 plays a role. PAI-1 levels are increased in patients with recurrent pregnancy losses (RPL), preeclampsia, intrauterine growth restriction (IUGR), gestational diabetes mellitus (GDM) in the previous pregnancy, endometriosis and polycystic ovary syndrome (PCOS). In general, an increased expression of PAI-1 in the blood is associated with an increased risk for infertility and a worse pregnancy outcome. GDM and PCOS are related to the genetic role of the 4G/5G polymorphism of PAI-1. This review provides an overview of the current knowledge of the role of PAI-1 in reproductive diseases. PAI-1 represents a promising monitoring biomarker for reproductive diseases and may be a treatment target in the near future.

RESUMEN

Antithrombin (AT) deficiency is a rare hereditary thrombophilia with a mean prevalence of 0.02 % in the general population, associated with a more than ten-fold increased risk of venous thromboembolism (VTE). Within this multicenter retrospective clinical analysis, female patients with inherited AT deficiency were evaluated concerning the type of inheritance and extent of AT deficiency, medical treatment during pregnancy and postpartally, VTE risk as well as maternal and neonatal outcome. Statistical analysis was performed with SPPS for Windows (19.0). A total of 18 pregnancies in 7 patients were evaluated, including 11 healthy newborns ≥37th gestational weeks (gw), one small for gestational age premature infant (25th gw), two late-pregnancy losses (21st and 28th gw) and four early miscarriages. Despite low molecular weight heparin (LMWH) administration, three VTE occurred during pregnancy and one postpartally. Several adverse pregnancy outcomes occurred including fetal and neonatal death, as well as severe maternal neurologic disorders occurred. Patients with substitution of AT during pregnancy in addition to LMWH showed the best maternal and neonatal outcome. Close monitoring with appropriate anticoagulant treatment including surveillance of AT levels might help to optimize maternal and fetal outcome in patients with hereditary AT deficiency.

RESUMEN

Background: Recent years have seen a considerable shift from male doctors to female doctors in the field of gynecology. Female doctors are traditionally more involved with planning and maintaining their family. For gynecology, this could be associated with a risk that research activities will decrease, particularly if results are published in scientific journals. Methods: In view of this shift, a comparative observational study was carried for 2022 in which 1306 publications were matched to 1786 female and male doctors reported on the websites of the 44 locations of university gynecology departments in Germany. In addition, the volume of publications issued between 2014 and 2022 was compared for Germany, France, the United Kingdom, and the United States. In Germany, the volume of publications in Gynecology was additionally compared with the publication outputs of the specialties Urology and Trauma Surgery. Results: Since 2014, the increase in the numbers of publications in the field of Gynecology in Germany was lower (225%) than that of the countries with which it was compared (238%/252%/260% for F/UK/USA). When Gynecology was compared with other medical specialties in Germany, the number of publications in Urology were found to have increased at a lower rate (196%) while the number of publications in the field of Trauma Surgery increased by more (286%) than that of Gynecology. At the start of 2023, the percentage of women who were working as doctors at the lowest hierarchical level (junior doctor) was 81%. The publication output per capita of female doctors working at lower levels in the medical hierarchy, i.e., working as junior doctors and senior physicians, was between 40% and 80% lower than that of male doctors working at the same level. However, female directors published as much as male directors did. In the lower hierarchy levels, men were up to 14% more likely to be without an academic title. Predictors for more extensive publication activities by young female and male doctors include the extent and quality of publications by doctors in senior positions, the presence of a comprehensive cancer center or an institute for human genetics at the location where the young doctors were working, and joint publications with foreign authors. Conclusion: For the German Society of Gynecology and Obstetrics, the results suggest a number of approaches to promote young researchers. The support provided to young female doctors is especially important as this should help to retain them as junior researchers over the long term.

RESUMEN

STUDY QUESTION: Could the protamine-1 to protamine-2 mRNA ratio serve as a biomarker to estimate the fertilizing capacity of sperm from men taking part in an IVF/ICSI programme? SUMMARY ANSWER: The protamine mRNA ratio clearly discriminates between fertile and subfertile men and sperm with a normal protamine mRNA ratio exhibit a higher fertilizing capacity in IVF/ICSI. WHAT IS KNOWN ALREADY: Aberrant sperm protamine ratios are associated with male factor infertility and mRNA ratio is comparable with protein ratio (due to transcriptional stop in elongating spermatids). STUDY DESIGN, SIZE, DURATION: The study population was drawn from subfertile men, whose female partners participated in IVF or ICSI programmes between September 2010 and February 2012. Normozoospermic healthy volunteers served as controls. Sperm cells were lysed, mRNA extracted, reverse transcribed and subjected to real-time quantitative PCR using specific primer pairs for protamine-1 and protamine-2. Relative protamine-1 and protamine-2 mRNA levels were analysed with the Mann-Whitney U-test (two-tailed). PARTICIPANTS/MATERIALS, SETTING, METHODS: Quantitative RT-PCR for protamines 1 and 2 has been performed in ejaculates from 32 normozoospermic volunteers (control, University Clinic Giessen, Germany) and 306 patients, whose female partners took part in an IVF (n = 76; University Clinic Hamburg, Germany and Shanghai Jiaotong University, China) or an ICSI (n = 230; University Clinic Munich, Germany and Kinderwunschzentrum Wiesbaden, Germany) programme. MAIN RESULTS AND THE ROLE OF CHANCE: The sperm protamine mRNA ratio in normozoospermic men (0.98 ± 0.3) differed significantly from that of ICSI patients (Munich 0.81 ± 0.1; Wiesbaden 0.78 ± 0.2; P < 0.001), while processed samples obtained from IVF patients revealed a normal protamine mRNA ratio (Hamburg 1.0 ± 0.07; Shanghai 1.0 ± 0.54). Normal protamine mRNA ratios were associated with a significantly higher total motile sperm count and a significantly higher percentage of progressively motile sperm. Sperm with a normal protamine mRNA ratio revealed a higher fertilization capacity (fc) in both IVF (53.6% of patients with fc > 80%; P = 0.017) and ICSI (65.1% of patients with fc > 70%; P = 0.028). LIMITATIONS, REASONS FOR CAUTION: The protamine mRNA ratio in an individual sperm cell used for ICSI may be different from the overall value obtained from a semen aliquot. WIDER IMPLICATIONS OF THE FINDINGS: Data are in line with current literature and suggest the protamine mRNA ratio as a diagnostic marker to estimate the fertilizing capacity of sperm. STUDY FUNDING: The German Research Foundation (DFG) to K.S., W.W. and A.P. (STE 892/9-2), as well as to A.S. and H.C.O. (SP721/1-3). COMPETING INTEREST(S): None.

RESUMEN

PURPOSE: The M2 haplotype in ANXA5 as well as antitrophoblast antibodies predispose to recurrent pregnancy loss (RPL). Since M2/ANXA5 can be a factor for development of antiphospholipid antibodies (aPL), this study aimed to trace a possible association of M2 with antitrophoblast antibodies. METHODS: One hundred patients with two or more consecutive, idiopathic RPLs were divided in two subgroups, JEG-3(+) (n = 42) and JEG-3(-) (n = 58), according to the anti-JEG-3 reactivity measured in subjects' sera. Both subgroups were genotyped for ANXA5 promoter haplotypes and genetic frequencies were compared to available fertile and control populations, as well as within the subgroups. RESULTS: M2/ANXA5 was generally enriched in the JEG-3 screened cohort of RPL patients in comparison to fertile and population controls. Despite the relatively higher abundance of the haplotype in the JEG-3(-) sample as compared to JEG-3(+) patients and in the JEG-3(-) primary RPL subset in particular, compared to the rest of patients, there was no statistically significant difference between both, JEG-3(-) and JEG-3(+) subgroups. CONCLUSION: It appears that the haplotype M2/ANXA5 is not associated with the presence of anti-trophoblast antibodies. Our finding indicates that anti-trophoblast antibodies are a class of molecules that differ from aPL and from anti-b2-GPI antibodies, apparently not directed to same or similar epitopes that aPL and anti-b2-GPI would recognize.

RESUMEN

PROBLEM: Some studies suggest intravenous intralipid infusions (IVIL) to be effective in the treatment of immune-mediated pregnancy failure. To this date it remains to be established, how IVIL might protect pregnancy and therefore a specific subgroup of RPL patients that might benefit from IVIL has not been defined. Anti-trophoblast antibodies (ATAb) have been associated with RPL and appear to mediate immune pathology. We have shown, that ATAb in vitro decrease HCG- and progesterone production pointing to a mechanism how ATAb interfere with normal pregnancies. We have measured ATAb-activities in patients undergoing off label IVIL-treatment. METHOD OF STUDY: Ten RPL-patients with positive ATAb, determined by using the choriocarcinoma cellline JEG-3 and flow cytometry as described before, and otherwise unexplained RPL, received off-label IVIL during pregnancy. Two ATAb-positive RPL patients preferred expectant management. In addition, ATAb-activity was studied in pregnancies of two healthy ATAb-negative volunteers without miscarriages. RESULTS: In RPL patients receiving IVIL, relative ATAb-activity decreased from an average of 56.8±17.0% to 20.8±11.0% (P < .001). The two RPL-patients without IVIL, aborted at 6+3gw and 7+4gw and embryonic genetic testing revealed euploid karyotypes. During pregnancies of the two healthy ATAb-negative individuals, ATAb-activities remained negative (16±9.8%) without significant changes (P = .22). Nine of the 10 pregnancies receiving IVIL proceeded uneventful with healthy newborns ≥37gw. One patient receiving IVIL aborted at 7+6gw and embryonic genetic-testing revealed a trisomy 16. No specific side effects concerning IVIL were noted. CONCLUSIONS: Intralipid preparations during pregnancies of ATAb-positive RPL-patients significantly reduce ATAb-activities and this may indicate a therapeutic mechanism of IVIL.

RESUMEN

Objective To compare steroid profiles in the follicular fluid (FF) from women homozygous for the methylenetetrahydrofolate reductase (MTHFR) 677C>T mutation and wildtype controls and to correlate it with the folic acid administration scheme applied at the time of oocyte retrieval. Design Retrospective single center study. Subjects and Methods Infertile patients treated by using assisted reproductive techniques were genotyped routinely for the MTHFR 677C>T mutation. In 2006 they had received folic acid supplementation doses of 400 µg daily per os. This group was designated Group-400 (n = 10). From 2008 onwards, all of our infertility patients received a daily dose of 800 µg folic acid per os. Women from this group were designated Group-800 (n = 28). FF were collected and a panel of steroid hormones (estradiol, estrone, estriol, cortisol, progesterone, 17-OH progesterone, testosterone, androstenedione, aldosterone, DHEA, and DHEA-S) was measured by isotope dilution liquid chromatography-tandem mass spectrometry employing atmospheric pressure photo ionization (APPI). Results In Group-400, the FF hormone profile confirmed a significant reduction of estradiol in homozygous 677TT carriers (0.52 ± 0.08-fold, exact p = 0.032) and for the first time also revealed significantly reduced estriol concentrations in these individuals (0.54 ± 0.05-fold, p = 0.016), as compared to wildtype controls. In Group-800, no significant differences were found for concentrations of any of the steroid hormones between homozygous 677TT carriers and wildtype controls. Conclusions The current findings support and extend previous reports on reduced concentrations of specific steroid hormones in follicular fluids of homozygous MTHFR 677C>T mutation carriers. The restoration of the FF hormone profile by elevated-dose folic acid supplementation might impact performing ART in infertile women with the MTHFR 677TT-genotype. Further adequately powered studies are necessary to verify our finding and to demonstrate the clinical effect of enhanced folic supplementation on ovarian function.

RESUMEN

BACKGROUND: Preliminary empirical data indicates a substantial impact of the COVID-19 pandemic on well-being and mental health. Individuals with minoritized sexual and gender identities are at a higher risk of experiencing such negative changes in their well-being. The objective of this study was to compare levels of well-being among cis-heterosexual individuals and individuals with minoritized sexual and gender identities during the COVID-19 pandemic. METHODS: Using data obtained in a cross-sectional online survey between April 20 to July 20, 2020 (N = 2332), we compared levels of well-being (WHO-5) across subgroups (cis-individuals with minoritized sexual identities, individuals with minoritized gender identities and cis-heterosexual individuals) applying univariate (two-sample t-test) and multivariate analysis (multivariate linear regression). RESULTS: Results indicate overall lower levels of well-being as well as lower levels of well-being in minoritized sexual or gender identities compared to cis-heterosexual individuals. Further, multivariate analyses revealed that living in urban communities as well as being in a relationship were positively associated with higher levels of well-being. Furthermore, a moderation analysis showed that being in a relationship reduces the difference between groups in terms of well-being. CONCLUSION: Access to mental healthcare for individuals with minoritized sexual and gender identities as well as access to gender-affirming resources should be strengthened during COVID-19 pandemic. Healthcare services with low barriers of access such as telehealth and online peer support groups should be made available, especially for vulnerable groups.

RESUMEN

PURPOSE: We tested the hypothesis that the application of intranasal oxytocin (8 IU) following intrauterine insemination (IUI) would increase pregnancy rates, without causing major side effects. METHODS: Randomized, double-blind, placebo-controlled pilot study: eighty-six couples with idiopathic infertility, polycystic ovary syndrome and/or male sub-fertility treated with 132 homologous IUI cycles with nasal application of placebo or 8 IU oxytocin following IUI. RESULTS: In 132 IUI cycles of 86 women, 17 pregnancies were achieved, accounting for a pregnancy rate of 12.9% (17/132) per IUI cycle. The pregnancy rates were 13.4% (9/67) per IUI cycle in the placebo group, and 12.3% (8/65) per IUI cycle in the oxytocin group, the difference not being statistically significant. No relevant side effects were observed in both groups. CONCLUSIONS: Intranasal application of 8 IU oxytocin has no major side effects but at the same time did not affect pregnancy rates after IUI in our population. This study does not exclude that a larger patient group, a different time interval between oxytocin application and IUI, higher or multiple oxytocin applications or a different mode of application would have achieved different effects on pregnancy rates.

RESUMEN

BACKGROUND/AIM: The incidence of human papilloma virus (HPV)-related head and neck squamous cell carcinoma (HNSCC) has been increasing in the last decades. Analysis of oral brushing or rinsing samples for screening or stratification could potentially improve screening and prevention. PATIENTS AND METHODS: Oral brushes and mouthwashes were taken from 20 patients with HPV-associated HNSCC before definite therapy. HPV genotyping was performed for the detection of 14 high-risk HPV subtypes and correlated to DNA isolated from tumor tissue. RESULTS: Ten of 20 patients were tested HPV positive by using either method. There was a significant correlation between macroscopic visibility of tumor and positive HPV detection (p<0.001) and HPV detection and tumor size (p<0.001). HPV was detected in all macroscopically visible tumors. Half of the HPV cases who had macroscopically invisible tumors were missed by both methods. CONCLUSION: Both techniques are limited in the detection of macroscopically non-visible and small tumors. Therefore, the application of these techniques for screening or diagnosis of HNSCC is not recommended.

RESUMEN

OBJECTIVE: Analysis of serum beta-human chorionic gonadotropin (beta-hCG) levels on standardized days after oocyte retrieval (OR) following single blastocyst transfer to predict pregnancy outcome after assisted reproductive technology. DESIGN: Retrospective study. SETTING: Private fertility center. POPULATION: A total of 230 women with an intact intrauterine pregnancy 21 days after OR and a vital term delivery (n = 191) or a miscarriage (< 10+0 gestational weeks) (n = 39) in the course of the pregnancy following single blastocyst transfer between 1999 and 2008. METHODS: Blood was sampled 11, 14 and partly 21 days after OR. The serum concentration of total beta-hCG was measured by an automated quantitative immunoassay. Receiver operating characteristic curves were generated to calculate sensitivity and specificity. MAIN OUTCOME MEASURES: A total of 509 beta-hCG measurements. RESULTS: The mean beta-hCG concentrations on days 11, 14 and 21 after OR were significantly lower in the group of patients with a miscarriage compared to the group with a term delivery (p = 0.02, < 0.001 and < 0.001 respectively). With the cut-off values of 15 mIU/mL, 80 mIU/mL and 1500 mIU/mL on days 11, 14 and 21, the positive predictive value was 89%, 93% and 92%. The negative predictive value was 28%, 40% and 54%. CONCLUSIONS: The predictive value of a single beta-hCG measurement for pregnancy outcome after single blastocyst transfer increases between days 11 and 21 after OR. A single beta-hCG measurement on day 14 may balance the accuracy of prediction and the necessity of an early reassuring test.
