Psychosis risk for lesbian, gay, and bisexual individuals: systematic review and meta-analysis.

The social defeat hypothesis posits that low status and repeated humiliation increase the risk for psychotic disorders (PDs) and psychotic experiences (PEs). The purpose of this paper was to provide a systematic review of studies on risk of PDs and PEs among lesbian, gay, or bisexual (LGB) people and a quantitative synthesis of any difference in risk. PubMed, PsycINFO, Embase, and Web of Science were searched from database inception until January 30, 2024. Two independent reviewers assessed the eligibility and quality of studies, extracted effect sizes, and noted the results of mediation analyses. Using a random effects model we computed pooled odds ratios (ORs). Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed. The search identified seven studies of PDs and six of PEs. As for PDs, the unadjusted (2.13; 95% confidence interval 0.72-6.34) and covariate-adjusted pooled OR (2.24; 1.72-3.53) were not significantly increased for LGB individuals. After exclusion of a study of limited quality, both the unadjusted pooled OR (2.77; 1.21-6.32) and the covariate-adjusted pooled OR (2.67; 1.53-4.66) were significantly increased. The pooled ORs were increased for PEs: unadjusted, pooled OR = 1.97 (1.47-2.63), covariate-adjusted, pooled OR = 1.85 (1.50-2.28). Studies of PE that examined the mediating role of several variables reported that the contribution of drug abuse was small compared to that of psychosocial stressors. The results of a study in adolescents suggested a protective effect of parental support. These findings suggest an increased psychosis risk for LGB people and support the social defeat hypothesis.

Religious Affiliation, Internalized Homonegativity and Depressive Symptoms: Unveiling Mental Health Inequalities among Brazilian Gay Men.

INTRODUCTION: Different religious narratives associate same-sex sexuality, in its various manifestations, with moral deviation or sin. Gay men who are socialized in more religious communities appear to experience and internalize greater levels of homonegativity, as well as to present greater indicators of depressive symptoms. The purpose of this study was to evaluate indicators of perceived homonegativity in the community and internalized, and signs/symptoms of depression reported by Brazilian gay men with a nominal religion and compare them to those reported by Atheists or Agnostics. METHOD: Our sample comprised 194 Brazilian gay men, distributed into three groups: Christians (Protestants and Catholics, n = 71; 36.6%); Spiritualists (Kardecists or religions of African origin, n = 52; 26.8%) and Atheists or Agnostics (n = 71; 36.6%). The following measurement instruments were used: sociodemographic questionnaire, Internalized Homophobia Scale and Beck Depression Scale. RESULTS: High mean scores of depression were verified in all groups, and 60% of the sample presented some level of depression. There was a higher level of self-reported homonegativity among Christians and Spiritualists compared to that reported by Atheists or Agnostics, with the differences between the groups being significant. The regression analysis indicated a significant effect of religion on homonegativity, but not on depression. CONCLUSION: Our results suggest that gay men's chronic exposure to non-affirming religious affiliation contexts may harm the construction of a positive gay identity and should be taken into consideration when addressing mental health inequalities of sexual minorities.

Syphilis among Roma community: a single-center experience in Bulgaria (socio-demographic data collection, 2008-2022).

INTRODUCTION: With a population of roughly 11 million, the Roma (Gypsies) are the largest ethnic minority in Europe, particularly in the countries of Central and Eastern Europe. A number of serious socioeconomic issues, such as poor health, low levels of education, unemployment, discrimination, criminal activity, high-risk sexual behavior, and a high rate of illnesses, including STDs, are present in their society.

Invasive Neisseria meningitidis subtype C in gay, bisexual and other men who have sex with men: a systematic review.

INTRODUCTION: Outbreaks of invasive Neisseria meningitidis subtype C in networks of gay, bisexual and other men who have sex with men (MSM) have been reported. We aimed to explore any factors seen in MSM with invasive N.meningitidis subtype C. METHOD: We searched three bibliographical databases for manuscripts written in English exploring at least one factor seen in MSM with invasive N. meningitidis subtype C published up to May 2024. Following an initial search, removal of duplicates and abstract review, two authors independently reviewed full-text manuscripts and performed a risk of bias assessment using the Joanna Briggs Institute toolkit. Narrative data were synthesised to generate themes. RESULTS: 16 manuscripts were included in this review from the USA (n=10), Germany (n=2), France (n=2), Canada (n=1) and Italy (n=1) and consisted of nine case series, four cross-sectional studies, two case reports and one case-control study published between 2003 and 2024 involving 236 MSM with invasive N. meningitidis subtype C, of which at least 64 died. We have highlighted some demographic (African-American or Hispanic identity in the USA, living with HIV), behavioural (kissing, sharing drinks, visiting sex-on-premises venues, visiting gay-oriented venues, using websites/mobile phone apps to meet sexual partners, recreational drug use, multiple and non-regular sexual partners) and infection (previous Chlamydia trachomatis, Treponema pallidum, Neisseria gonorrhoeae, Mpox) factors in MSM with invasive N. meningitidis subtype C. CONCLUSION: These data serve as an important resource to inform and target future public health strategies and outbreak control measures for the prevention of invasive N. meningitidis subtype C in MSM.

Does use of anal cytology as a triage test improve the performance of high-risk human papillomavirus screening in gay and bisexual men for anal cancer prevention?

Anal high-risk human papillomavirus (HRHPV) testing-based anal cancer screening gay and bisexual men (GBM) is associated with high sensitivity, but low specificity. We report the potential role of triage use of anal cytology with HRHPV testing in detecting 12-month persistent anal high-grade squamous epithelial lesions (HSIL) in a cohort of GBM in Sydney, Australia. Participants were GBM from the Study of the Prevention of Anal Cancer (SPANC) who underwent annual anal HPV testing, cytology, and high-resolution anoscopy (HRA)-guided histology. The sensitivity and specificity of five screening algorithms based on HRHPV test results with triage use of anal cytology (atypical squamous cells of undetermined significance (ASCUS) and atypical squamous cells, cannot exclude HSIL (ASC-H) used as referral thresholds) were compared to these of HRHPV testing and anal cytology alone. A total of 475 men who had valid HRHPV, cytological, and histological results at both baseline and first annual follow-up visits were included, median age 49 years (inter-quartile range: 43-56) and 173 (36.4%) GBM with human immunodeficiency virus. Of all triage algorithms assessed, two had comparable sensitivity with HRHPV testing alone in detecting persistent anal HSIL, but ~20% higher specificity and 20% lower HRA referral rates. These two algorithms involved the immediate referral of those with HPV16 and for those with non-16 HRHPV either immediate or delayed (for 12 months) referral, depending on cytology result at baseline. Triage use of anal cytology in GBM testing positive for anal HRHPV increases specificity and reduces referral rates while maintaining high sensitivity in detection of HSIL.

Beyond the Iron Throne: exploring the representation of homosexuality in the series Game of Thrones.

Introduction: This research delves into the representation of homosexuality in the television series Game of Thrones, adapted from George R.R. Martin's A Song of Ice and Fire saga. The study focuses on the navigation and portrayal of homosexual identities and relationships within a historically patriarchal and heteronormative genre. Methodology: A qualitative research approach, specifically thematic analysis, was utilized to scrutinize the portrayal of homosexuality across all eight seasons and 73 episodes of Game of Thrones. The analysis encompassed pivotal scenes, character development, and dialogues related to homosexual representation. Findings: Thematic analysis revealed several significant themes concerning the representation of homosexuality, including heteronormativity, the interplay of love and war, and the societal and personal impacts of sexual identity. The series portrays the challenges and resilience of homosexual characters, such as Renly Baratheon and Loras Tyrell, against a backdrop of political intrigue and personal ambition. However, the depiction at times veers into sensationalism, which may potentially desensitize viewers to the real-life struggles faced by LGBTQ+ individuals. Discussion: The study findings suggest that while Game of Thrones aims to depict homosexual relationships with complexity and depth, it also risks perpetuating negative stereotypes and sensationalizing trauma for dramatic effect. This dual portrayal underscores the broader challenge within popular media to balance representation with responsible storytelling. The study emphasizes the necessity for more nuanced and empathetic portrayals of marginalized groups to promote greater understanding and inclusivity in media narratives.

Do men who have sex with men recognise syphilis symptoms? A syphilis awareness campaign in Amsterdam, the Netherlands.

INTRODUCTION: Syphilis incidence is rising among gay, bisexual and other men who have sex with men (GBMSM). To improve early health-seeking behaviour, we developed an online syphilis symptom score tool for GBMSM to self-identify a higher likelihood of infectious syphilis and promoted its use via an online and offline awareness campaign. METHODS: From October 2018 through September 2019, a dedicated website on syphilis including the online symptom score tool was promoted. The reach of the campaign was measured by website metrics and the completion of the self-assessment tool. The impact of the campaign was assessed by comparing the monthly number of syphilis serology tests and the percentages of infectious syphilis diagnoses at the Centre for Sexual Health (CSH) in Amsterdam between three periods: 12 months preceding, 12 months during and 6 months after the campaign. RESULTS: During the campaign, 20 341 visitors viewed the website. A total of 13 499 (66.4%) visitors started the self-assessment algorithm, and 11 626 (86.1%) completed it. Prior to the campaign, the mean number of syphilis tests per month was 1650 compared with 1806 per month during the campaign (p=0.02). In the 6 months after the campaign, the mean number of tests per month was 1798 (compared with the period of the campaign, p=0.94). Prior to the campaign, the percentage of infectious syphilis diagnoses was 2.5% compared with 3.0% during the campaign (p=0.009). The percentage of infectious syphilis diagnoses in the 6 months after the campaign was 2.2% (p<0.0001 compared with the period of the campaign, and p=0.045, compared with the period prior to the campaign). CONCLUSIONS: Although we did not find definite proof of a (sustained) effect, syphilis symptoms awareness campaigns deserve further evaluation and improvements to help those suspected of syphilis to get tested.

Updating prospective marriage and divorce data on Norwegian cohorts of two-sex marriages from 1886 until 2018 with same-sex marriages from 1993 until 2018.

This paper presents an update to the previously published dataset known as prospective marriage and divorce data on Norwegian cohorts of two-sex marriages from 1886 until 2018. This update adds prospective data from all same-sex marriages formed in Norway between 1993 and 2018, with annual follow-up for 25 years, totaling 26 cohorts and 5,187 marriages. The data list the number of marriages that ended in divorce throughout each year of follow-up. The data contain information about the age of both spouses, the number of divorces from each cohort in the total population of marriages, as well as divorces among marriages formed in urban and rural areas of the country. Marriages formed within a calendar year are pooled into cohorts, and each pair is examined annually to ensure that the same two people remain married. As a result, the method is equivalent to the initial dataset on two-sex marriages presented in the first dataset.

Examining the Fraternal Birth Order Effect and Sexual Orientation: Insights from an East European Population.

The development of human sexual orientation remains a complex and multifaceted subject. It is often studied but its origins continue to elude us. In this preregistered study, our primary objective was to demonstrate the fraternal birth order effect (FBOE), which assumes a higher prevalence of older brothers in gay men than in their straight counterparts and which has also been recently recorded in lesbian women. Our second aim was to explore any potential impact of the FBOE on anal-erotic role orientation (AERO), both in gay and straight men. Our study sample included 693 gay men, 843 straight men, 265 lesbian women, and 331 straight women from Czechia and Slovakia. Employing a conventionally parameterized logistic regression model, we substantiated the FBOE among both gay men (OR = 1.35 for maternal older brothers) and lesbian women (OR = 1.71). These outcomes were confirmed by a more nuanced parameterization recently proposed by Blanchard (2022). Nonmaternal older brothers did not exhibit a significant influence on their younger brothers' sexual orientation. Contrary to some earlier reports, however, our data did not establish the FBOE as exclusive to gay men with the receptive AERO. Furthermore, our observations indicated a lower offspring count for mothers of gay men compared to mothers of straight men. Emphasizing the positive FBOE outcomes, we acknowledge the need for caution regarding the various options that can be used to estimate the familial influences on sexual orientation.

Divergence in Chinese Sexual Attitudes: An Age-Period-Cohort Analysis.

A crucial component of comprehending societal change is understanding how sexual attitudes have evolved over time. The substantial and typical changes in China have created an ideal quasi-experimental design and a wealth of empirical data for tracking the evolution of sexual attitudes. However, existing research has failed to adequately analyze the temporal trends in Chinese sexual attitudes. This study employed an age-period-cohort framework to investigate changes in public sexual attitudes, including premarital sex, extramarital sex, and homosexuality. And it further delved into these attitudes in light of two unique aspects of Chinese society: urban-rural divide and political status. It explored the contributing elements and potential processes of changing public sexual attitudes in China using data from seven waves of national social survey conducted from 2010 to 2021. The findings indicated that public sexual attitudes became more conservative with age; the period effect exhibited a fluctuating upward trend, indicating a general increase in acceptance of the three sexual attitudes; notable differences in sexual attitudes among cohorts were identified. The divergence in sexual attitudes was significantly influenced by urban-rural divide and political status.

Estimated prevalence and associations of sexually transmissible bacterial enteric pathogens in asymptomatic men who have sex with men: a systematic review and meta-analysis.

OBJECTIVE: The reservoir of sexually transmissible bacterial enteric pathogens in asymptomatic men who have sex with men (MSM) may impact future outbreaks, and the evolution of antimicrobial resistance. We aimed to estimate the pooled prevalence and explore any factors associated with Shigella spp, Campylobacter spp, diarrhoeagenic Escherichia coli and Salmonella spp in asymptomatic MSM using the random effects model. METHODS: We searched Embase, MEDLINE, CINAHL and Web of Science Core Collections for manuscripts published up to February 2024. One author screened citations and abstracts; two authors independently conducted a full-text review. We included manuscripts which measured the prevalence of Shigella spp, Campylobacter spp, diarrhoeagenic E. coli and Salmonella spp in asymptomatic MSM. Quality and risk of bias was assessed independently by two authors using the Joanna Briggs Institute critical appraisal tools. We calculated pooled prevalence and CIs using the random effects model. RESULTS: Six manuscripts were included in the final review. The manuscripts were from Australia (n=2), the UK (n=2), the Netherlands (n=1) and the USA (n=1) and included data from 3766 asymptomatic MSM tested for bacterial enteric pathogens. The prevalence of Shigella spp was 1.1% (95% CI 0.7% to 1.7%), Campylobacter spp 1.9% (95% CI 1.5% to 2.5%), diarrhoeagenic E. coli 3.8% (95% CI 2.1% to 6.7%) and Salmonella spp 0.3% (95% CI 0.1% to 0.6%). Two manuscripts demonstrated that the detection of bacterial enteric pathogen was more frequent in asymptomatic MSM using HIV-pre-exposure prophylaxis (PrEP), living with HIV, reporting <5 new sexual partners in the past 3 months, reporting insertive oral-anal sex and group sex compared with MSM testing negative. CONCLUSION: Despite a small number of manuscripts, this review has estimated the pooled prevalence, and highlighted some possible associations with sexually transmissible bacterial enteric pathogens in asymptomatic MSM, which can inform future clinical guidelines, public health control strategies and research to increase our understanding of transmission and the evolution of antimicrobial resistance.

The Association Between Active Membership in Voluntary Organizations and Homonegativity.

OBJECTIVES:  Homonegativity adversely affects the health and well-being of homosexuals in society, making it vital to identify factors associated with it. This study investigates whether active membership in voluntary organizations correlates with homonegativity, examining how this varies by gender and age. METHODS:  Using the World Values Survey data (2017-2022) from 87,777 participants in 63 countries, we performed binary logistic regression to assess relationships between homonegativity and factors including socioeconomic status, demographics, and voluntary activity participation. RESULTS:  Our findings suggest that active membership in certain voluntary organizations correlates with homonegativity levels among both men and women across various age groups. Specifically, active participation in sports or recreational organizations, professional associations, art, music, or educational organizations, and humanitarian or charitable organizations was found to be negatively correlated with homonegativity in specific gender-age groups, albeit with varying degrees of association strength. CONCLUSION:  This study highlights the complex relationship between engagement in voluntary organizations and attitudes toward homosexuality, with significant differences observed across gender and age. While identifying a correlation rather than causation, this study suggests the importance of societal and community participation in fostering more tolerant views toward homosexuals. Furthermore, our analysis indicates that demographic and socioeconomic variables, the political freedom of the respondent's country, and the respondent's life satisfaction are also linked to homonegativity.

Beyond Translation: Exploring the Stigmatization of Rainbow Works Translation Under Frame Theory.

Drawing on Goffman's frame theory, this study examines the attitudes of nine Chinese university teacher translators in translating rainbow works, ranging from hesitancy to resistance. The primary objective is to uncover the frames of stigmatization inherent in their negative attitudes toward rainbow works translation. The research clarifies the identities of perpetrators and victims in these frames leading to stigmatization. Findings indicate that various stigmatization events in rainbow works translation share a common feature-an unfavorable depiction of rainbow culture and related elements, encompassing the rainbow community, works, and translators. Perpetrators and victims vary across events, demonstrating diversity. The research interprets stigmatization in rainbow works translation at individual, institutional, and sociocultural levels. Providing a unique Chinese perspective, the study contributes to international understanding of stigmatization in a heteronormative society. It challenges traditional Chinese norms, advocates reevaluating identity labels for the rainbow community, and underscores the importance of addressing translators' circumstances in translating rainbow works within specific societal contexts.

Attitudes of Medical Students Toward Sexual Minorities: A Multicentric Survey from the Medical Education Without Discrimination Project.

This study, as a part of the 'Medical Education without Discrimination (MED) Project," focuses on investigating attitudes toward sexual minorities and demographics among Turkish medical students. In the needs assessment phase of MED Project, a survey covering demographics, sexual orientation, attitudes toward sexual minorities, and Index of Attitudes Toward Homosexuals by Hudson & Ricketts (6-point Likert) was conducted among 523 medical students of one public and two nonprofit private medical schools in Istanbul. Of the students, 4.2% declared themselves as non-heterosexual. The findings highlight that medical students are on the verge of homophobia (44th percentile). Homophobia was significantly higher among public university students, males, younger individuals, those who originated from underdeveloped settlements, those who grew up with mothers who did not graduate from university, those who considered themselves happier, and those without LGBTI+ acquaintances. Of the respondents, 14.1% do not perceive LGBTI+ people as equals within the community, and 75.7% assert that they would conceal their own LGBTI+ identity if they were part of this community. This study highlights that the need for targeted interventions in medical education in line with the global commitment to reduce inequalities and promote inclusive health care.

Synergistic interaction between pay-it-forward incentives and recreational drug use on hepatitis B virus and hepatitis C virus testing among men who have sex with men in China.

OBJECTIVES: Pay-it-forward incentives effectively promote hepatitis B virus (HBV) and hepatitis C virus (HCV) testing among men who have sex with men (MSM) by offering free testing and donation opportunities. This study aims to explore the interaction between pay-it-forward incentives and recreational drug use on HBV and HCV testing uptake among Chinese MSM. METHODS: We pooled data from two pay-it-forward studies that aimed to promote dual HBV and HCV testing among MSM in Jiangsu, China. We explored factors associated with hepatitis testing uptake in the two study groups and examined the interaction between pay-it-forward incentives and recreational drug use on hepatitis testing uptake. RESULTS: Overall, 511 MSM participated in these two studies, with 265 participants in the pay-it-forward incentives group and 246 participants in the standard-of-care group. Among these participants, 59.3% in the pay-it-forward incentive group and 24.8% in the standard-of-care group received dual HBV and HCV testing, respectively. In the pay-it-forward incentives group, participants who used recreational drugs in the past 12 months (adjusted OR (AOR)=1.83, 95% CI 1.09 to 3.06) were more likely to receive dual HBV and HCV testing, compared with those who never used recreational drugs, whereas in the standard-of-care group, those who used recreational drugs were less likely to receive dual HBC and HCV testing (AOR=0.38, 95% CI 0.18 to 0.78). MSM with higher community connectedness (AOR=1.10, 95% CI 1.00 to 1.21) were also more likely to receive hepatitis testing with pay-it-forward incentives. There was a synergistic interaction on both the multiplicative (ratio of ORs=4.83, 95% CI 1.98 to 11.7) and additive scales (the relative excess risk of interaction=2.97, 95% CI 0.56 to 5.38) of pay-it-forward incentives and recreational drug use behaviours on dual HBV and HCV testing uptake among MSM. CONCLUSION: Pay-it-forward incentives may be particularly useful in promoting hepatitis testing among MSM who use recreational drugs.

Assessing COVID-19 Vulnerability Among HIV-positive Men Who Have Sex With Men in Korea: The Role of Vaccination and Sexual Behaviors.

OBJECTIVES: Comorbidities increase susceptibility to severe coronavirus disease 2019 (COVID-19) infections, but limited information has been published regarding human immunodeficiency virus (HIV) and COVID-19 co-infections. This study explored the relationships among socioeconomic characteristics, sexual behaviors, and COVID-19 infection rates among Korean men who have sex with men (MSM) who are also living with HIV. METHODS: Data were collected through a web survey aimed at members of the largest gay portal site in Korea, supported by the National Research Foundation of Korea (n=1005). The primary independent variables included COVID-19-related vaccinations and sexual behaviors. The dependent variable was the incidence of COVID-19 infection among respondents during the pandemic. For statistical analysis, hierarchical multiple logistic regression was performed, controlling for potential confounding variables. RESULTS: Model I indicated that older MSM were less likely to contract COVID-19 (adjusted odds ratio [aOR], 0.98; 95% confidence interval [CI], 0.96 to 0.99). Model II demonstrated that HIV-positive MSM were nearly twice as likely to be infected with COVID-19 compared to their HIV-negative counterparts (aOR, 1.97; 95% CI, 1.14 to 3.41). Furthermore, even after accounting for COVID-19 vaccination status in model III, HIV-positive MSM continued to show a higher risk of infection (aOR, 1.93; 95% CI, 1.12 to 3.35). CONCLUSIONS: The findings of this study indicate that HIV-positive MSM are at an increased risk of contracting COVID-19, even when their vaccination status is considered. Therefore, it is essential to prioritize the prevention of COVID-19 infections in HIV-positive individuals by administering appropriate antiretroviral therapy and ensuring adherence to public health guidelines.

Wakefield's Harm-Based Critique of the Biostatistical Theory.

Jerome Wakefield criticizes my biostatistical analysis of the pathological-as statistically subnormal biological part-functional ability relative to species, sex, and age-for its lack of a harm clause. He first charges me with ignoring two general distinctions: biological versus medical pathology, and disease of a part versus disease of a whole organism. He then offers 10 counterexamples that, he says, are harmless dysfunctions but not medical disorders. Wakefield ends by arguing that we need a harm clause to explain American psychiatry's 1973 decision to declassify homosexuality. I reply, first, that his two distinctions are philosophic fantasies alien to medical usage, invented only to save his own harmful-dysfunction analysis (HDA) from a host of obvious counterexamples. In any case, they do not coincide with the harmless/harmful distinction. In reality, medicine admits countless chronic diseases that are, contrary to Wakefield, subclinical for most of their course, as well as many kinds of typically harmless skin pathology. As for his 10 counterexamples, no medical source he cites describes them as he does. I argue that none of his examples contradicts the biostatistical analysis: all either are not part-dysfunctions (situs inversus, incompetent sperm, normal-flora infection) or are indeed classified as medical disorders (donated kidney, Typhoid Mary's carrier status, latent tuberculosis or HIV, cherry angiomas). And if Wakefield's HDA fits psychiatry, the fact that it does not fit medicine casts doubt on psychiatry's status as a medical specialty.
