We investigated men who have sex with men's (MSM) location preferences for long-acting injectable pre-exposure prophylaxis (LA-PrEP). MSM (n = 1076) who completed the 2021 American Men's Internet Survey, were currently prescribed oral PrEP, and expressed LA-PrEP interest reported location preferences for receiving LA-PrEP: healthcare provider (HCP) setting, pharmacy, or at-home. HCP settings were preferred by 60% of participants; 26% preferred home and 14% preferred pharmacy. In adjusted models, high healthcare stigma was associated with preferring pharmacy and at-home versus HCP, while high friends/family stigma was associated with preferring HCP settings versus pharmacy. Healthcare access history was associated with preference for HCP setting versus home. Being 25 to 29 or 30 to 29 years old versus 40+ was associated with preferring HCP versus home. Private insurance was associated with location preferences. Findings support the need for multiple LA-PrEP service locations to best reach MSM and highlight multiple complex factors that influence such preferences. Plain Language Summary: Location Preferences for Receiving Long-Acting Injectable Pre-Exposure Prophylaxis (LA-Prep) among Men who have Sex with Men (MSM) We investigated location preferences among men who have sex with men (MSM) for receiving long-acting injectable pre-exposure prophylaxis (LA-PrEP), a medication approved to prevent human immunodeficiency virus (HIV). MSM (n = 1076) who completed the 2021 American Men's Internet Survey, were currently prescribed oral PrEP, and expressed interest in switching to LA-PrEP reported preferences for where they would like to receive LA-PrEP. Responses included healthcare provider (HCP) setting, pharmacy, or at-home. HCP settings were preferred among 60% of MSM; 26% preferred home, and 14% preferred pharmacy. In adjusted models, high healthcare stigma was associated with preferring pharmacy and at-home over HCP setting, while high friends/family stigma was associated with preferring HCP settings over pharmacy. Healthcare access history was associated with preference for HCP setting over home. Being younger (25-29 or 30-29 vs 40+ years old) was associated with preferring HCP over home. Private insurance was associated with various location preferences. Findings support the need for multiple LA-PrEP service location options to best reach MSM and highlight multiple complex factors that influence their preferences. [ABSTRACT FROM AUTHOR]

The introduction of the undetectable equals untransmittable (U = U) statement significantly reduces HIV stigma and provides an empirical basis for achieving "zero transmission." U = U messaging has gained increasing support and is well-developed in several countries. However, the current status of accurate knowledge of U = U and its associated factors among men who have sex with men (MSM) in China remians unclear. We conducted a cross-sectional survey among MSM recruited in Chengdu, China, from March to May 2022 to investigate the percentage of those who knew U = U accurately and to explore associations between sexual risk behaviors, HIV testing, socio-behavioral measures, and accurate knowledge of U = U. Of 497 MSM included in our study, 23.4% (116/497) had accurate knowledge of U = U. More than half of the participants (63.2%, 314/497) reported multiple sexual partnerships, 15.7% (78/497) used substance during sex, 37.4% (186/497) reported inconsistent condom use, and 76.1% (378/497) took HIV testing in the past six months. Factors associated with accurate knowledge of U = U among MSM included substance use during sex (multivariate odds ratios ORm = 1.96; 95%CI: 1.13–3.41), HIV status tested in the last six months (ORm = 2.07; 95%CI: 1.14–3.77), HIV-related literacy (ORm = 1.41; 95%CI: 1.14–1.74) and perceived higher risk of HIV infection (ORm = 1.11; 95%CI: 1.02–1.21). The findings indicate that great challenges need to be conquered for U = U achievement among the MSM population in Chengdu, China. Intervention strategies should be prioritized in health education on high-risk behaviors such as group sex and substance use, information provision and counseling of U = U in HIV testing services, and encouraging U = U knowledge sharing among MSM with their partners in China. Resumen: La introducción de la declaración "indetectable es igual a intransmisible" (Singla en inglés: U = U) reduce significativamente el estigma asociado al VIH y proporciona una base empírica para lograr la "transmisión cero." Los mensajes de U = U han ganado cada vez más apoyo y están bien desarrollados en varios países. Sin embargo, el estado actual del conocimiento preciso sobre U = U y sus factores asociados entre los hombres que tienen sexo con hombres (HSH) en China sigue siendo incierto. Realizamos una encuesta transversal entre HSH reclutados en Chengdu, China, de marzo a mayo de 2022, para investigar el porcentaje de participantes que conocían U = U con precisión y explorar las asociaciones entre comportamientos sexuales de riesgo, pruebas de VIH, medidas socio-comportamentales y el conocimiento preciso de U = U. De los 497 HSH incluidos en nuestro estudio, 23.4% (116/497) tenían un conocimiento preciso de U = U. Más de la mitad de los participantes (63.2%, 314/497) informaron tener múltiples parejas sexuales, el 15.7% (78/497) usaron sustancias durante el sexo, el 37.4% (186/497) informaron un uso inconsistente de condones, y el 76.1% (378/497) se realizaron pruebas de VIH en los últimos seis meses. Los factores asociados con el conocimiento preciso de U = U entre los HSH incluyeron el uso de sustancias durante el sexo (razones de probabilidad multivariadas ORm = 1.96; IC95%: 1.13–3.41), pruebas recientes de VIH (ORm = 2.07; IC95%: 1.14–3.77), la alfabetización relacionada con el VIH (ORm = 1.41; IC95%: 1.14–1.74) y la percepción de un mayor riesgo de infección por VIH (ORm = 1.11; IC95%: 1.02–1.21). Estos hallazgos destacan que se deben superar grandes desafíos para lograr el objetivo de U = U entre la población HSH en Chengdu, China. Las estrategias de intervención deben priorizarse en la educación sanitaria sobre comportamientos de alto riesgo, como el sexo grupal y el uso de sustancias, la provisión de información y el asesoramiento sobre U = U en los servicios de pruebas de VIH, y fomentar la difusión del conocimiento de U = U entre los HSH y sus parejas en China.

Abstract Background Pre-exposure prophylaxis (PrEP) is a highly effective pharmaceutical intervention that prevents HIV infection, but PrEP uptake across the US has been slow among men who have sex with men (MSM), especially among Black/African American (B/AA) and Hispanic /Latino (H/L) MSM. This study investigates the acceptability and essential components of a peer-driven intervention (PDI) for promoting PrEP uptake among MSM, with a specific focus on B/AA and H/L communities. Methods We conducted 28 semi-structured, qualitative interviews with MSM in southern New England to explore the components of a PDI, including attitudes, content, and effective communication methods. A purposive sampling strategy was used to recruit diverse participants who reflect the communities with the highest burden of HIV infection. Results Of 28 study participants, the median age was 28 years (interquartile range [IQR]: 25, 35). The sample comprised B/AA (39%, n = 11) and H/L (50%, n = 14) individuals. Notably, nearly half of the participants (46%) were current PrEP users. We found that many participants were in favor of using a PDI approach for promoting PrEP. Additionally, several participants showed interest in becoming peer educators themselves. They emphasized the need for strong communication skills to effectively teach others about PrEP. Moreover, participants noted that peer education should cover key topics like how PrEP works, how effective it is, and any possible side effects. Conclusions Our study shows that effective PDIs, facilitated by well-trained peers knowledgeable about PrEP, could enhance PrEP uptake among MSM, addressing health disparities and potentially reducing HIV transmission in B/AA and H/L communities.

Abstract Background Chlamydia and gonorrhea notifications are rapidly rising in men who have sex with men (MSM). Currently, there are limited data on the prevalence of chlamydia and gonorrhea across various anatomical sites. Our study aimed to explore the prevalence, association and changing trends of urethral and rectal chlamydia and gonorrhea among MSM in Guangdong Province, China. Methods We analyzed data among MSM attending sexually transmitted infections (STI) clinics in the Guangdong governmental sentinel network between 2018 and 2022. Chi-square tests were used to compare the difference, Join-point regressions for analyzing changing trends, and multivariate logistic regressions for examining associated factors. Results We included 4856 men in the analysis. Rectal chlamydia significantly increased from 13.8% to 26.4% over the past 5 years (average annual percentage change [AAPC] 19.2%, 95%CI 1.0-40.6, p = 0.043). After adjusting for covariates, chlamydia infection positively associated with main venue used to seek sexual partners (aOR = 2.31, 95%CI 1.17–4.55), having regular sexual partners in the past 6 months (aOR = 3.32, 95%CI 1.95–5.64), receiving HIV counselling and testing services (aOR = 2.94, 95%CI 1.67–5.17), receiving peer education (aOR = 1.80, 95%CI 1.14–2.83), infection with syphilis (aOR = 2.02, 95%CI 1.02–4.01) and infection with gonorrhea (aOR 7.04, 95% CI 3.01–16.48). Gonorrhea infection positively associated with having regular sexual partners in the past 6 months (aOR = 3.48.95%CI 1.16–10.49), and infection with chlamydia (aOR 7.03, 95% CI 2.99–16.51). Conclusions To conclude, our findings reveal a high prevalence of chlamydia infections among MSM, particularly in the rectal area. Comprehensive chlamydia and gonorrhea health services are necessary for MSM to improve sexual health.

Abstract Background In Vietnam and other global settings, men who have sex with men (MSM) have become the population at greatest risk of HIV infection. Although HIV pre-exposure prophylaxis (PrEP) has been implemented as a prevention strategy, PrEP outcomes may be affected by low persistence and adherence among MSM with unhealthy alcohol use. MSM have a high prevalence of unhealthy alcohol use in Vietnam, which may affect PrEP outcomes. Methods Design: We will conduct a two-arm hybrid type 1 effectiveness-implementation randomized controlled trial of a brief alcohol intervention (BAI) compared to the standard of care (SOC) at the Sexual Health Promotion (SHP) clinic Hanoi, Vietnam. Participants: Sexually active MSM (n=564) who are newly initiating PrEP or re-initiating PrEP and have unhealthy alcohol use will be recruited and randomized 1:1 to the SOC or BAI arm. A subgroup of participants (n=20) in each arm will be selected for longitudinal qualitative interviews; an additional subset (n=48) in the BAI arm will complete brief quantitative and qualitative interviews after completion of the BAI to assess the acceptability of the intervention. Additional implementation outcomes will be assessed through interviews with clinic staff and stakeholders (n=35). Intervention: Study participants in both arms will receive standard care for PrEP clients. In the BAI arm, each participant will receive two face-to-face intervention sessions and two brief booster phone sessions, based on cognitive behavioral therapy and delivered in motivational interviewing informed style, to address their unhealthy alcohol use. Outcomes: Effectiveness (PrEP and alcohol use) and cost-effectiveness outcomes will be compared between the two arms. Intervention implementation outcomes (acceptability, feasibility, adoption) will be assessed among MSM participants, clinic staff, and stakeholders. Discussion This proposed trial will assess an alcohol intervention for MSM with unhealthy alcohol use who initiate or re-initiate PrEP, while simultaneously preparing for subsequent implementation. The study will measure the effectiveness of the BAI for increasing PrEP persistence through reducing unhealthy alcohol use in a setting where excessive alcohol consumption is a normative behavior. If effective, implementation-focused results will inform future scale-up of the BAI in similar settings. Trial registration NCT06094634 on clinicaltrials.gov. Registered 16 October 2023.

Background The 2022 monkeypox (mpox) outbreak in Los Angeles County (LAC) emphasized the need to prepare for emergent infectious disease outbreaks. Vaccination and promotion of sexual risk reduction practices appeared successful in LAC, as mpox cases declined starting in August. Nonetheless, questions persisted regarding the effectiveness of targeting vaccinations and the role of sexual risk reduction in reducing mpox cases. Methods We collaborated with the LAC Department of Public Health to develop a microsimulation for men who have sex with men (MSM). This model tracked mpox dynamics by age, race/ethnicity, and HIV status and was calibrated and validated against surveillance data. We simulated counterfactual scenarios to understand the effects of variation in vaccination rates, timing of vaccination rollout, vaccine allocation, and sexual contact rates. Results In the simulation, doubling the vaccination rate reduced cumulative cases over a 40-week time horizon by 13% but would necessitate 88 995 additional doses. Initiating vaccination 2 weeks earlier decreased cases by 11%, while an 8-week delay yielded a 20% increase in cases. A 3-week earlier decrease in sexual contact rates reduced cumulative cases by 60%, while a 3-week delay resulted in a 95% increase. Prioritizing people with HIV (PWH) for vaccination reduced cumulative cases, while allocating vaccines to a single racial/ethnic group was not effective. Conclusions Our study highlights the significance of policies to support timely vaccination and sexual partnership reduction to address mpox outbreaks among MSM. These findings also underscore the need to target vulnerable risk groups, such as PWH. [ABSTRACT FROM AUTHOR]

This study quantitatively and qualitatively examined the prevalence, frequency, and content of discrimination exposure among gay, bisexual, and other sexually minoritized men (SMM) within sexual minority contexts. Participants were an online, U.S. national sample of 14,133 SMM who reported discrimination exposure within sexual minority contexts targeting: body type, race, sexual behavior, HIV status, gender expression, age, and income/employment. Quantitative analyses included prevalence percentages and frequencies and ANOVAs, t-tests, and correlations to examine the frequency of discrimination exposure type across participant race/ethnicity, sexual identity, gender identity, HIV status, age, and income. Qualitative analyses included conventional content analysis of responses to an open-ended discrimination exposure item. Results showed that discrimination exposure was nearly universal (99%). Discrimination exposure frequency was lowest among White men and, other than for income/employment discrimination exposure, highest among Asian/Pacific Islander men. For several discrimination types, exposure frequency was highest among groups targeted by group-specific negative stereotypes (e.g., Black men were exposed to the most income/employment discrimination). Qualitative analyses highlighted specific exposures to discrimination targeting body type, race/ethnicity, gender identity, attractiveness, education, and intersections between forms of discrimination. Over 69% of write-in responses were relevant to online/app-based discrimination. Findings underscore the importance of examining individual and intersectional discrimination exposure targeting marginalized social positions within sexual minority communities, particularly in online/app contexts.

Literature is sparse regarding men's attitudes towards male sexual assault and the role that the sexuality of those involved may have. Despite the high prevalence of chemsex and GHB (gamma-hydroxybutyrate) participation among men who have sex with men, no study has yet investigated attitudes towards such. Utilising a community sample of 141 UK men, participants were randomly assigned into one of six conditions based on victim sexuality (heterosexual or homosexual) and the drug used present during the sexual assault (chemsex, chemical submission, or no drugs). All participants completed the Male Rape Victim and Perpetrator Blaming Scale and Victim-Blaming Empathy Scale to measure victim-blame and empathy attributions. Results of a two-way MANOVA revealed a significant difference between participant gender and empathic ratings, with heterosexual participants significantly less likely to empathise than their homosexual counterparts. A non-significant difference was observed between the conditions alongside a non-significant interaction. Nevertheless, results indicate that victims in the chemsex condition, along with heterosexual victims, encountered the greatest victim-blaming attributions and the lowest rates of participant empathy overall. Findings overall appear to indicate a general decline in victim-blame attitudes towards men who have sex with men, though a level of uncertainty was apparent among the sample. Implications and limitations of the work are discussed alongside the importance of future research and psychoeducation interventions. [ABSTRACT FROM AUTHOR]

Background: Combining pathogen reduction technology (PRT) with blood screening may alleviate concerns over the risk of transfusion‐transmitted infections (TTI) and support changes in blood donor selection to potentially increase blood availability. This study aimed to estimate the residual risk of human immunodeficiency virus (HIV), hepatitis B virus (HBV), and hepatitis C virus (HCV) transfusion‐transmission in Canada after implementing PRT, while eliminating deferrals for sexual risk behaviors. Study Design and Methods: A probabilistic approach that combined Bayesian networks with Monte Carlo simulations was used to estimate the risk of transfusing HIV‐, HBV‐, or HCV‐contaminated blood components. Different scenarios were considered to compare the current residual risk after PRT implementation, with and without donor deferral criteria for sexual risk behaviors. Donor profiles and blood component outcomes were simulated based on a literature review including the prevalence and incidence of HIV, HBV, and HCV in the Canadian blood donor population; the use of current blood screening assays; and HIV, HBV, and HCV blood donor viral loads. Results: In the universal PRT scenario (i.e., with PRT/without deferral criteria), the estimated risks of HIV, HBV, and HCV transmission were significantly lower than those in the currently observed scenario (i.e., without PRT/with deferral criteria). Conclusions: This risk model suggests that PRT for platelets and plasma (and eventually for RBCs when available) significantly reduces the residual risks of HIV, HBV and HCV transfusion‐transmission and could enable the removal of blood donor deferral criteria for sexual risk behaviors.

Young MSM (YMSM), aged 15–24, account for nearly half of new HIV infections in Thailand. Pre-exposure prophylaxis (PrEP) is an effective prevention medicine for populations at substantial HIV risk, yet YMSM frequently have suboptimal uptake of and adherence to PrEP. We conducted 35 in-depth interviews with YMSM to explore barriers and facilitators of both PrEP initiation and adherence. Interviews also elicited the perceptions and experiences of healthcare providers (HCPs) working with YMSM at three clinics in Bangkok. Primary barriers to PrEP initiation were limited accessibility, insufficient knowledge, and efficacy concerns; HCPs identified no-to-low self-perception of HIV risk, pre-existing health problems, fears of side effects, and living in distant provinces as barriers to PrEP initiation. YMSM primarily reported PrEP information and self-perceptions of elevated HIV risk as facilitators to PrEP initiation. Additionally, forgetfulness and low HIV risk awareness were common barriers to PrEP adherence. Reminders were a prominent facilitator of PrEP adherence alongside disclosure to close relationships, the routinization of regimens, and convenient facilities. HCPs regarded counseling as the leading facilitator of PrEP adherence. By understanding the barriers/facilitators of PrEP use, the current study seeks to help develop evidence-informed PrEP intervention programs among YMSM while considering cultural sensitivity.

Pre-exposure prophylaxis (PrEP) is an effective tool for human immunodeficiency virus (HIV) prevention. The purpose of this study is to identify correlates of PrEP retention using patient data from an urban, publicly funded safety-net clinic in Washington, DC. Cox proportional hazards regression, logistical regression, and survival curves were used to assess the association of age, gender, race/ethnicity, insurance, number of partners, and sexually transmitted infection (STI) diagnosis at PrEP initiation with time on PrEP. From August 2016-December 2020, 1,126 people were prescribed PrEP - patients were mostly Black (44.8%) or Latinx (30.4%) and identified as cisgender men (84.6%). Half had no insurance (49.1%), with the remaining patients reporting private (28.9%) or public (21.5%) insurance. Age at PrEP prescription ranged from 15 to 66 with 80% being 20 to 39 years. For the 87.7% (n = 987) of patients who discontinued PrEP, mean PrEP time was 158 days and median was 28 days. The highest rates of discontinuation were observed within the first month with 44.3% discontinuing by day 30, 52.3% by 3 months, and 73.2% by 1 year. Cisgender women, transgender persons, and those younger than 30 years were more likely to discontinue PrEP. Latinx and patients with less than 3 male partners in the last 90 days were less likely to discontinue PrEP. We demonstrated a high level of PrEP uptake among populations disproportionally affected by HIV. Future analyses are needed to examine ways of reducing barriers to PrEP initiation and improving PrEP adherence. [ABSTRACT FROM AUTHOR]

ObjectiveThis study aimed to update baseline data on monkeypox (mpox)-related knowledge and vaccination willingness among human immunodeficiency virus (HIV) diagnosed and suspected males.MethodsThe cross-sectional survey was conducted in Changsha, a provincial capital in China, during 5 JULY to 5 SEPTEMBER 2023. Among the three study groups, the participants in the “previously diagnosed” group were recruited from a cohort of HIV-infected patients. The “newly diagnosed” and the “suspected” groups were recruited from the outpatients and grouped according to their confirmatory test results. The the exploratory factor analysis was firstly applied to capture the latent structure of participants’ response to the questionnaire about monkeypox. The component and factor scores were compared between groups using the Kruskal-Wallis H tests. The chi-square test was then used to assess the difference of mpox vaccination willingness between MSM and non-MSM in each group. Finally, multivariate logistic regression analysis was performed to identify the determinants of vaccination willingness.ResultsA total of 481 males were included in the final analysis. The results revealed that there was a gap in knowledge about monkeypox between the three participant groups. The vaccination willingness rate of HIV-infected participants was above 90%, while the rate in the HIV-suspected group was 72.60%. Multivariate logistic regression analysis revealed that the previously diagnosed group (adjusted odds ratio [aOR] = 0.314, 95% confidence interval [CI]: 0.105–0.940) and the suspected group (aOR = 0.111, 95% CI: 0.034–0.363) had a lower level of vaccination willingness and they were referred to the newly diagnosed group. Participants in the age groups ranging 25–34 (aOR = 0.287, 95% CI: 0.086–0.959) and 35–44 (aOR = 0.136, 95% CI: 0.039–0.478) years showed a lower level of vaccination willingness, referred to the 15–24 year age group. A better knowledge about monkeypox was associated with a higher level of vaccination willingness (aOR = 1.701, 95% CI: 1.165–2.483). Additionally, a considerable percentage of heterosexual individuals in each group indicated their acceptance of monkeypox vaccines.ConclusionAn overall high level of vaccination willingness was observed among HIV-infected and-suspected male individuals with disparities noted among those with different HIV infection status, knowledge levels of monkeypox, and age. Addressing the existing knowledge gap and engaging people with persistent risks—regardless of their sexual orientation—for a timely HIV diagnosis may facilitate vaccine-based mitigation measures against monkeypox.

Pre-exposure prophylaxis (PrEP) is a highly effective biomedical prevention strategy that remarkably reduces HIV transmission risk. Although PrEP has been available in Nepal since 2019, very little is known about PrEP use among MSM in Nepal. This study aimed to examine PrEP awareness and its use among Nepali MSM and the factors influencing its adoption. A cross-sectional survey was conducted among MSM in Nepal between October and December 2022 (N = 250). Bivariate analysis and logistic regression were performed to determine factors associated with awareness and use of PrEP. In the study population, 59.6% of participants were aware of PrEP, however, only 30.4% of them had utilized it. The odds of PrEP awareness were higher among participants who had completed high school or above (aOR = 4.1; 95% CI = 1.8–9.6), those with health insurance coverage (aOR = 6.9; 95% CI = 2.1–22.3) and had tested for HIV (aOR = 21.2; 95% CI = 8.3–53.9). Similarly, participants who identified as gay (aOR = 3.4; 95% CI = 1.4–8.4), had visited a doctor within the past 6 months (aOR = 2.9; 95% CI = 1.2–6.5), had previously tested for HIV (aOR = 12.3; 95% CI = 3.4–44.7), and had been diagnosed with sexually transmitted infections (aOR = 7.0; 95% CI = 2.5–19.5) were more likely to have used PrEP. Our results highlight the critical importance of healthcare providers engaging in providing care for MSM, including facilitating as well as discussions about PrEP. In addition, there is a pressing need for innovative strategies (e.g., peer educators, social media, online facilitating technologies) to disseminate PrEP knowledge and reduce stigma surrounding PrEP.

Background: Anal cancer disproportionately affects sexual and gender minority individuals living with HIV. High-resolution anoscopy (HRA) is an in-clinic procedure to detect precancerous anal lesions and cancer, yet prospective data on factors associated with HRA attendance are lacking. We examined whether anal HPV sampling at home versus in a clinic impacts HRA uptake and assessed HRA acceptability. Methods: Sexual and gender minority individuals were randomised to home-based self-sampling or clinical sampling. All were asked to attend in-clinic HRA 1 year later. We regressed HRA attendance on study arm using multivariable Poisson regression and assessed HRA acceptability using χ 2 tests. Results: A total of 62.8% of 196 participants who engaged in screening attended HRA. Although not significant (P = 0.13), a higher proportion of participants who engaged in clinic-based screening attended HRA (68.5%) compared to home-based participants (57.9%). Overall, HRA uptake was higher among participants with anal cytology history (aRR 1.40, 95% CI 1.07–1.82), and lower among participants preferring a versatile anal sex position versus insertive (aRR 0.70, 95% CI 0.53–0.91), but did not differ by race or HIV serostatus. In the clinic arm, persons living with HIV had lower HRA attendance (42.9%) versus HIV-negative participants (73.3%) (P = 0.02) and Black non-Hispanic participants had lower HRA attendance (41.7%) than White non-Hispanic participants (73.1%), (P = 0.04). No differences in attendance by race or HIV status were observed in the home arm. Conclusions: HRA uptake differed significantly by race and HIV status in the clinic arm but not the home arm. Anal cancer disproportionately affects men who have sex with men living with HIV. We examined whether anal HPV sampling at home versus in a clinic impacts uptake of high-resolution anoscopy (HRA), an in-clinic procedure. Anal cytology history and insertive anal sex position were associated with higher HRA uptake, and attendance differed by race and HIV status in the clinic arm. Given that people living with HIV and Black men who have sex with men are disproportionately affected by anal cancer, interventions are needed to support their clinic attendance.

BackgroundMen who have sex with men (MSM) are vulnerable to HPV infection. This study aims to explore the HPV infection status at different sites among HIV-positive MSM, HIV-negative MSM, and men who have sex with women (MSW), and to investigate their willingness to receive HPV vaccination.MethodsFrom September 2023 to April 2024, three groups were recruited in Tianjin, China. Participants completed an electronic self-administered questionnaire, which included demographic information, knowledge related to sexually transmitted diseases, behavioral information, and willingness to receive the HPV vaccine. Samples were collected from the anal region, genitals, and oral cavity for HPV typing.ResultsA total of 1,559 participants were recruited, including 300 HIV-positive MSM, 600 HIV-negative MSM, and 659 MSW. The HPV infection prevalence for any site were 62.0, 53.7 and 8.3%, respectively (p

Background: While cancer is a leading cause of death worldwide, significant disparities exist in care access in low- and middle-income countries (LMICs). In Liberia, screening and treatment for anal cancers remain limited, and are exacerbated among vulnerable groups, including men who have sex with men (MSM). Screen-triage-treat models for cancerous lesions have been successful in reducing cervical cancer mortality, but the feasibility of this approach has not been studied for anal cancers in a low-resource context. Objective: The aim of this study is to determine the feasibility of implementing a screen-triage-treat model for anal high-grade squamous intraepithelial lesions (aHSIL) among MSM in Liberia. Methods: This descriptive study represented a collaboration between Stop AIDS in Liberia (SAIL) and health institutions in Liberia and the USA. MSM and transgender participants were recruited through convenience sampling with SAIL peer-educators. A survey validated by SAIL experts assessed demographics and sexual risk factors. Participants underwent anal self-swabbing for high-risk human papillomavirus (HPV) and offered human immunodeficiency virus (HIV) testing. Those with positive results were offered a screen-triage-treat model through high-resolution anoscopy (HRA) and infrared coagulation (IRC). Data were cleaned and analyzed in SPSS. Findings: Among 110 participants, most were single (n = 94, 88%) and without formal employment (n = 21, 75%). Participants engaged in regular anal (n = 64, 60%), oral (n = 62, 58%), and receptive sex (n = 58, 54%), and sex with women (n = 51, 48%). Nearly 20% of participants reported being HIV positive (n = 21). In all, 50 participants (45%) tested positive for anal high-risk HPV, 34 (68%) elected to undergo HRA, and 10 (84%) were treated with IRC. Of those who underwent HRA, 75% tested HIV positive. Conclusions: Our findings suggest that a screen-triage-treat model presents a feasible option to identify and reduce the incidence of anal cancer among MSM in Liberia. The screen-triage-treat model, with proven success in management of cervical dysplasia, may be a viable option to treat aHSIL for anal cancer prevention in LMICs.

Previous research has demonstrated associations between experiences of microaggressions and negative mental and physical health outcomes, and national organizations such as the Centers for Disease Control and Prevention have acknowledged racism as a public health issue. Individuals with multiple marginalized identities, such as young Black men who have sex with men and transgender women, are commonly affected by discrimination and stigma, contributing to health disparities. One possible path by which microaggressions are linked to negative health outcomes for these groups is their impact on individuals' decisions to conceal their sexual identity, in some cases leading to increased stress and use of maladaptive coping strategies. We surveyed 280 young Black male (86%) and transgender or non-binary (14%) individuals between the ages of 16–25 years old (M = 21.68, SD = 2.73) who reported being recently sexually active with men about their experiences with intersectional microaggressions, concealment of their sexual identity, psychological distress, and substance use before and during sexual activity. Structural equation modeling revealed that experiences of microaggressions were associated with greater sexual identity concealment, and concealment partially mediated the relationship between microaggressions and psychological distress. While microaggressions were associated with greater substance use, sexual identity concealment did not mediate this relationship. Findings have implications for addressing health disparities among this population. [ABSTRACT FROM AUTHOR]

Summary: Background and Objectives: Serovar L1–L3 of Chlamydia trachomatis (CT) causes lymphogranuloma venereum (LGV). A surge in LGV‐cases has been observed among HIV‐positive men who have sex with men (MSM). Discrimination between LGV and non‐LGV is pivotal since it has major treatment implications. Here, we aimed to determine the prevalence and characteristics of LGV among CT‐infections. Patients and Methods: All CT‐positive results from 04/2014–12/2021 at the four largest Austrian HIV and STI clinics were evaluated. Disease characteristics and patient demographics were analyzed. Results: Overall, n = 2,083 infections of CT were documented in n = 1,479 individual patients: median age was 31.4 years, 81% were male, 59% MSM, 44% HIV‐positive, 13% on HIV pre‐exposure‐prophylaxis. Available serovar analyses (61% [1,258/2,083]) showed L1–L3 in 15% (192/1,258). Considering only MSM with rectal CT‐infection, LGV accounted for 23% (101/439). Cases of LGV vs. other CT‐infections were primarily MSM (92% [177/192] vs. 62% [1,179/1,891], p < 0.001), more often HIV‐positive (64% [116/180] vs. 46% [631/1,376]; p < 0.001) and had frequently concomitant syphilis infection (18% [32/180] vs. 7% [52/749]; p < 0.001). LGV commonly manifested as proctitis (38% [72/192]) whereas 45% (87/192) were asymptomatic. Conclusions: Lymphogranuloma venereum accounted for 23% of rectal CT‐infections in MSM. Furthermore, 45% of all LGV‐cases were asymptomatic. In the absence of CT‐serovar analysis, a high LGV prevalence should be considered in risk‐populations and guide empiric treatment selection.

Objectives: This study aimed to investigate the prevalence of mpox virus (MPXV) infections in the general population consulting for routine sexually transmitted infections (STIs) in our Marseille public hospital. In fact, the recent worldwide MPXV outbreak mainly impacted men who have sex with men and the prevalence of MPXV infections in the general population remains poorly defined. Methods: All samples addressed routinely to our microbiological laboratory for STIs between July 1 and October 15, 2022 were screened with MPXV-specific quantitative polymerase chain reaction. Results: A total of 2688 samples from 1896 patients suspected of having STIs were tested and eight (0.4%) patients were incidentally diagnosed with MPXV infection, including six men and two women. MPXV was detected in rectal swabs (n = 2), urine (n = 2), vaginal swabs (n = 2), a urethral swab (n = 1), and a skin swab (n = 1). Conclusions: This study suggests that some MPXV infections are likely to be underdiagnosed because of their non-specific clinical presentation and/or insufficient clinical knowledge of the disease. Our data showed that systematic screening was particularly useful for detecting MPXV in patients without classic lesions or cases of asymptomatic carriage in patients reporting recent high-risk exposure and in patients presenting no obvious risk factor.

Objectives: This study aimed to assess the effects of COVID-19 nonpharmaceutical interventions (NPIs) on the human papillomavirus (HPV) epidemic among men who have sex with men (MSM) in Xinjiang, China. Methods: In our cohort study, we enrolled and followed HIV-negative MSM in Xinjiang, China, between 2016 and 2022. Anal swab samples were collected to test for HPV DNA. We used interrupted time series analysis to characterize the temporal trends in HPV prevalence, incidence, and clearance before (September 01, 2016, to July 16, 2020) and during the implementation of COVID-19 NPIs in Xinjiang (July 17, 2020, to March 31, 2022). We used binomial segmented regression models to estimate the impact of COVID-19 NPIs on HPV prevalence, incidence, and clearance. Results: We recruited 1296 MSM who contributed to a total of 5374 HPV tests in our study. COVID-19 NPIs were associated with a 37.9% decrease in the prevalence (prevalence ratio, 0.621; 95% confidence interval, 0.465-0.830), 52.2% decrease in the incidence (risk ratio, 0.478; 0.377-0.606), and 40.4% increase in the clearance (risk ratio, 1.404; 1.212-1.627) of HPV of any genotype after the implementation of COVID-19 NPIs in Xinjiang. Conclusion: COVID-19 NPIs may lead to lower transmission and higher clearance of HPV among MSM. Future studies are needed to clarify the longer-term impact of COVID-19 on the transmission and natural history of HPV among MSM.

Background: In Latvia outbreaks of the HAV were observed between 2008 and early 2010 and again in 2017–2018. However, the risks of introducing and spreading infection still exist, as the virus spreads easily when personal hygiene is not followed. Methods: To determine the spread of HAV subgenotypes in the territory of Latvia the VP1/P2A genomic region of HAV was amplified and sequenced for 259 case serum samples. The study carried out a molecular biological investigation and molecular epidemiological investigation. Demographic data (sex, age), disease data (hepatitis symptoms, hospitalization, vaccination) and epidemiology data (part of the outbreak, possible source of infection, recent travel) were collected. Based on the obtained sequences, the phylogenetic tree was built and analyzed for the homology and belonging to different isolated HAV clusters from other countries. Results: From the obtained data, it was concluded that HAV subgenotype IA had 13 clusters and 12 sporadic cases, HAV subgenotype IB had eight clusters and 11 sporadic cases, HAV subgenotype IIIA had one cluster and nine sporadic cases. It was found that the sources of infection among the investigated cases were different, they were mostly associated with contact with a patient with HAV, travel, as well as between persons who inject drugs and men who have sex with men, and the prevalence of HAV similar sequences was observed in different years. It was concluded that patients with HAV subgenotype IA had the longest hospitalization duration and averaged 9.3 days, while patients with subgenotype IB - 7.3 days, subgenotype IIIA - 7.7 days. Analyzing the data on vaccination, it was found that mostly all were not vaccinated or had an unknown vaccination status. Conclusions: All of this has led to the conclusion that the application of molecular biological methods of the HAV and a careful analysis of epidemiological data can help to better understand the ways of spreading the infection, investigate local outbreaks, detect cases of imported infection and track the recirculation of the virus.

Abstract Introduction Pre-exposure prophylaxis (PrEP) persistence among men who have sex with men (MSM) in real world clinical settings for HIV prevention is suboptimal. New longer-acting formulations of PrEP are becoming available, including injectables, subdermal implants, and other oral medications. These longer-acting formulations have the potential to improve retention among those who have challenges remaining adherent to daily oral PrEP. Methods We interviewed 49 MSM who had initiated but discontinued oral PrEP at three diverse clinics across the United States. We examined participants’ perspectives about long-acting PrEP formulations and how long-acting options could affect PrEP use using thematic analysis. Results Participants were not very knowledgeable about long-acting formulations of PrEP but were open to learning about them and considering use. Participants were concerned about safety and efficacy of products given that they were still newer and/or in development. Finally, participants had clear preferences for oral pills, injectables, and then subdermal implants and were most interested in options that reduced the number of visits to the clinic. Conclusion Long-acting formulations of PrEP are acceptable to MSM with suboptimal PrEP persistence and have the potential to improve PrEP persistence. However, many felt they needed more information on safety, efficacy, and use to consider these options. As these long-acting formulations are implemented, public health campaigns and clinical interventions to encourage may maximize uptake particularly among those who are not currently adherent to daily oral PrEP.

Summary: Background: Despite high rates of HIV transmission among men who have sex with men (MSM) in Lima, Peru, limited data exist on the sexual network characteristics or risk factors for secondary HIV transmission among MSM with uncontrolled HIV infection. We report the frequency of serodiscordant, condomless anal intercourse (CAI) and associated sexual network characteristics among MSM in Lima with detectable HIV viremia and compare to those with undetectable viremia. Methods: This cross-sectional analysis includes MSM who tested positive for HIV-1 during screening for a trial of partner management and STI control (June 2022–January 2023). Participants were tested for HIV, gonorrhoea, chlamydia, and syphilis, and completed questionnaires on their demographic characteristics, sexual identity and behaviour, sexual network structures and engagement in HIV care. Findings: Of 665 MSM, 153 (23%) had detectable (>200 copies/mL) viremia. 75% (499/662) of men living with HIV were previously diagnosed, with 94% (n = 469/499) reporting that they were on ART, and 93% (n = 436/469) virally suppressed. 96% (n = 147/153) of men with detectable viremia reported serodiscordant CAI with at least one of their last three sexual partners, and 74% (n = 106/144) reported the same with all three of their recent partners. In contrast, 62% (n = 302/489) of men with undetectable viral load reported serodiscordant CAI with all of their last three partners (p

BackgroundThe May 2022 global outbreak of monkeypox (MPX) poses a threat to the health of men who have sex with men. However, there is limited data on the willingness of MSM to receive monkeypox vaccination in Southern China. This study aimed to assess the knowledge of MPX, concerns regarding MPX, and willingness to receive monkeypox vaccination, as well as their correlates, among MSM in China.MethodsWe conducted a Web-based online survey of MSM in Southern China from August to September 2022. Data were collected on the socio-demographic characteristics, knowledge, worries, concerns regarding MPX and willingness to receive monkeypox vaccination. Multivariate logistic regression was employed to explore the factors associated with willingness to receive monkeypox vaccination.ResultsA total of 1903 participants completed the survey. Among them, approximately 69.9% reported being aware of MPX awareness, 94.1% of the participants supported the promotion of monkeypox vaccination. The majority of participants (91.4%) expressed their willingness to receive monkeypox vaccination. Participants who considered monkeypox vaccination safe [adjusted odds ratio (aOR) = 4.82, 95% CI: 1.35–17.18], agreed on the necessity of government promotion of monkeypox vaccination in China (aOR = 6.03, 95% CI: 1.07–33.93), believed in prioritizing monkeypox vaccination for MSM (aOR = 5.01, 95% CI: 1.10–22.71), and had friends or sexual partners who had already received the monkeypox or smallpox vaccination (aOR = 10.37, 95% CI: 2.11–50.99) are more likely to be vaccinated. Conversely, married individuals (aOR = 0.13, 95% CI: 0.03–0.47), those engaging in anal sex 4–6 times per week in the past 3 months (aOR = 0.26, 95% CI: 0.09–0.77) expressed hesitancy toward monkeypox vaccination.ConclusionThere was a high willingness to receive monkeypox vaccination among MSM in China. The hesitancy toward the monkeypox vaccine can be effectively mitigated by addressing concerns about its safety and potential adverse reactions. Moreover, increasing acceptance of the monkeypox vaccination among MSM and their peers is crucial, as social influence significantly impacts vaccine attitudes and behaviors.

Abstract Introduction There are no data on community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) infections in the context of the chemsex phenomenon. This study aimed to characterize CA-MRSA-related infections in a cohort of people living with HIV (PLWH) who engage in chemsex. Methods At the Hospital Clinic of Barcelona, from February 2018 to January 2022, we analyzed CA-MRSA infections diagnosed in a cohort of PLWH who engage in chemsex. Epidemiological, behavioral and clinical variables were assessed. Mass spectrometry identification and antimicrobial susceptibility testing were performed on MRSA isolates. Pulse field electrophoresis was used to assess the clonality of the MRSA strains. The presence of Panton-Valentine leukocidin was also investigated. Results Among the cohort of 299 participants who engage in chemsex, 25 (8%) with CA-MRSA infections were identified, 9 at baseline and 16 with incident cases; the cumulative incidence was 5.5% (95% CI: 3.2%, 8.8%). The most common drugs were methamphetamine (96%) and GHB/GBL (92%). Poly-consumption and slamming were reported by 32% and 46%, respectively. CA-MRSA was isolated from the infection sites of 20 participants, and CA-MRSA colonization was confirmed in the remaining 5 persons. Seventy-one percent had used antibiotics in the previous year. All participants presented with skin and soft tissue infections, 28% required hospitalization, and 48% had recurrence. Of the 23 MRSA isolates further studied, 19 (82,6%) belonged to the same clone. Panton-Valentine leukocidin was detected in all isolates. Conclusion PLWH who engage in chemsex may present with CA-MRSA infections. Clinical suspicion and microbiological diagnosis are required to provide adequate therapy, and CA-MRSA prevention interventions should be designed.

BackgroundThe 2022 multicountry mpox outbreaks predominantly affected gay, bisexual and other men who have sex with men (GBMSM) in non-endemic countries, including in the Netherlands. We conducted a survey-based assessment of the alignment between the risk factors associated with mpox diagnosis among GBMSM in the Netherlands and the eligibility criteria used in 2022 for vaccinating this group, with the aim to refine these criteria.MethodsAn online self-report survey was conducted among adult GBMSM in the Netherlands between 29 July and 30 August 2022, corresponding to the first month of the Dutch mpox vaccination campaign. GBMSM were recruited via advertisements on social media and gay dating apps. Participants reported on their sexual behaviour, mpox diagnosis, and/or (initial) mpox vaccination since the start of the outbreak. Covariables of mpox diagnosis and vaccination were assessed using logistic regression analyses.ResultsOf the 2,460 participants, 73 (3.0%, 95% CI 2.3–3.6%) were diagnosed with mpox and 485 (19.7%, 95% CI 18.1–21.3%) had received (initial) mpox vaccination. Using sample weighting, we estimated that, of the GBMSM population aged 18–80 years in the Netherlands, 1.1% (95% CI 0.7–1.6%) had been diagnosed with mpox and 7.8% (95% CI 6.8–8.9%) had received (initial) vaccination. HIV-PrEP use, living with HIV, reporting ≥20 sex partners in the past 12 months, and sex in sex venues/parties in the past 2 months were independent risk factors for mpox diagnosis. Except for sex in sex venues/parties, these variables were also independently associated with mpox vaccination.ConclusionThis study provides novel evidence regarding the degree to which the 2022 eligibility criteria for mpox vaccination align with the risk factors for mpox among GBMSM in the Netherlands. The findings contribute to a refinement of the eligibility criteria for mpox vaccination, to which sex in sex venues/parties should be added.

BackgroundThe epidemic of HIV infection among men who have sex with men (MSM) is a major public health concern in some parts of China, but data on trends in HIV incidence are limited. This study aimed to examine the trends in HIV incidence and factors associated with recent HIV infection among MSM in Jiangsu province, China, based on the limiting-antigen avidity enzyme immunoassay (LAg-Avidity-EIA) method.MethodsSix consecutive surveys were implemented among MSM throughout Jiangsu province from 2016 to 2021. Participants were recruited in three ways. Socio-demographic and behavioral information were collected through face-to-face interviews. Venous blood samples were taken to test for HIV and syphilis. HIV incidence was estimated using the LAg-Avidity-EIA method. Chi-square trend tests were used to observe trends over the years. Multivariate regression analyses were used to identify factors associated with recent HIV infection.ResultsA total of 15,401 participants were enrolled in the study. The prevalence of HIV infection ranged from 8.0 to 9.8%, with no consistent rise or fall over the years (P = 0.189). HIV incidence ranged from 5.0 to 9.0%, and no uptrend or downtrend was shown (P = 0.418). MSM who lived locally for more than 2 years (aOR = 1.366, P = 0.019), had a lack of comprehensive HIV knowledge (aOR = 1.643, P = 0.031), had engaged in unprotected anal intercourse (UAI) in the past 6 months (aOR = 7.373, P < 0.001), had been tested for HIV within 12 months (aOR = 1.292, P = 0.035), and tested positive for syphilis (aOR = 2.840, P < 0.001) were likely to be recently infected with HIV.ConclusionsHIV incidence among MSM has remained at a high level in Jiangsu province. In China, health education, condom use, and HIV/syphilis testing should continue to be top priorities for HIV prevention among MSM to reduce HIV transmission.

Background: Black/African American (B/AA) and Hispanic/Latino (H/L) men who have sex with men (MSM) are significantly less likely than white MSM to initiate pre-exposure prophylaxis (PrEP). A peer-driven intervention (PDI) may be an effective approach to addressing this disparity. In this study, we explored community member perspectives of a PDI to promote PrEP uptake among B/AA and H/L MSM. Methods: We conducted semi-structured interviews with B/AA and H/L HIV-negative MSM between August 2018 and October 2019 in Rhode Island, USA. Participants reported their perspectives and recommendations for a PDI. Data from participant responses were thematically analysed. Results: Of 15 MSM, the median age was 25 years (interquartile range: 22, 33). The majority identified as B/AA (53.3%), H/L (66.7%), and having a college education or above (53.3%). Most participants viewed a PDI positively and were willing to learn and promote PrEP among their peers. Participants identified and supported several potential intervention components, such as education about the benefit of PrEP, emphasising prevention-effective dosing, and clarifying no prevention effect towards other sexually transmitted infections. They preferred in-person meetings to electronic communication. Preferred characteristics of peer educators included compassion, good communication skills, and enthusiasm about PrEP. Conclusions: This in-depth qualitative interview suggested that a PDI approach is promising in promoting PrEP uptake, as it could deliver culturally appropriate education and encourage PrEP uptake via peer influence among B/AA and H/L MSM. Peer approach is effective in promoting health among hard-to-reach populations. This study aims to explore the feasibility of implementing a peer approach for improving pre-exposure prophylaxis (PrEP) use among Black/African American (B/AA) and Hispanic/Latino (H/L) men who have sex with men (MSM). Study findings will be used to develop a peer approach for a real-world implementation. Participants were interviewed for their perspectives on such a peer approach, including willingness to disseminate PrEP knowledge and potential barriers to initiating PrEP. [ABSTRACT FROM AUTHOR]

Multiple studies have described the relationship between discrimination and health outcomes among gay, bisexual, and other men who have sex with men (GBMSM). However, little attention has been paid to prejudiced events in workplace environments. Rooted in a social determinants of health framework, we sought to examine associations between sexuality-based workplace discrimination (SBWD) and health outcomes in an online survey of Canadian GBMSM (N = 7,872). A minority (6.5%) of GBMSM reported past-year SBWD, which was more common among those identified as queer, Latino, Aboriginal, single, or with annual income less than CAD $30,000. GBMSM partnered with a man or woman reported less SBWD than single men. After adjusting for sociodemographics, SBWD was positively associated with having discussed depression and anxiety with a healthcare provider, suicidality, sexually transmitted infections (STIs), and intimate partner violence (IPV). More GBMSM who reported SBWD rated their health as poor, as compared with those who did not report SBWD. This is the first study to examine SBWD as a social determinant of health among Canadian GBMSM. Findings document that despite the social and legal gains of the last three decades, about 1 in 15 GBMSM report recent workplace discrimination due to their sexuality, which threatens their health. Work-based policies and interventions are urgently needed to provide safer workplace environments for sexual minorities. [ABSTRACT FROM AUTHOR]

Background: men who have sex with men (MSM) are a high-risk group for human papillomavirus (HPV) infection, and the HPV vaccine is effective in preventing it. However, according to risk compensation theory, people may increase sexual risk behaviors after receiving HPV vaccination. Based on the Health Action Process Approach (HAPA), this study investigated the influencing factors to predict intention to reduce condom use (risk compensation intention) among MSM after taking HPV vaccination in southwest China. Methods: we conducted a cross-sectional study among 948 MSM in southwest China using a non-probability sampling method and an electronic questionnaire including sociodemographic characteristics, sexual risk behavior characteristics, HPV-related prevention behavior, and the HAPA scale. Confirmatory factor analysis was performed using a structural equation model. Results: among 948 MSM, the incidence rate of reducing the frequency of condom use was 14.1%. The structural equation model showed that self-efficacy (β = −0.378, p = 0.020) and positive outcome expectancy (β = 0.366, p < 0.05) had greater effects on behavioral intention, followed by negative outcome expectancy (β = −0.296, p < 0.05) and risk perception (β = −0.232, p < 0.05). Conclusions: risk compensation may not be a major barrier to receiving HPV vaccination among MSM. Nevertheless, the recognition of possible risk compensation is necessary to implement appropriate interventions to reduce the occurrence of risk compensation. [ABSTRACT FROM AUTHOR]

The association between HIV pre‐exposure prophylaxis (PrEP) and the natural history of human papillomavirus (HPV) has not been well documented. Our objective was to evaluate the impact of PrEP on the prevalence, incidence, and clearance of anal HPV among men who have sex with men (MSM). Sexually active, HIV‐negative MSM aged 18 years and older in Xinjiang, China since September 1, 2016, were enrolled in an ongoing observational cohort study of HPV. At baseline and every 6 months, an anal swab was taken to test for HPV and a questionnaire on sociodemographic characteristics and sexual behaviors was collected. Those who consented to receive PrEP were enrolled in an open‐label PrEP intervention study from November 1, 2019, to June 30, 2021. This study analyzed data from participants present in the HPV cohort between November 1, 2019, and June 30, 2021. We compared the prevalence, incidence, and clearance of anal HPV between men who received PrEP (PrEP users) and those who did not (non‐PrEP users), and compared men before and after initiating PrEP. We calculated prevalence ratios (PRs), incidence rate ratios (IRRs), and clearance rate ratios (CRRs) for both comparisons. Of the 870 participants present in the HPV cohort during the period between November 1, 2019, and June 30, 2021, 859 had adequate β‐globin for HPV genotype testing and were included in our study. Among them, 429 were PrEP users, while 430 were non‐PrEP users. Median age was 32 years (interquartile range [IQR]: 26–38). Among PrEP users, 217 were tested for anal HPV before PrEP initiation. PrEP users had lower prevalence of HPV 45, 51, and 54 (PRs: 0.27 [95% CI: 0.09–0.80], 0.42 [0.21–0.85], and 0.41 [0.17–0.99], respectively) and lower clearance of HPV 16 (CRR: 0.31 [0.10–0.91]) compared with non‐PrEP users. PrEP users exhibited lower prevalence of HPV 51 (PR: 0.31 [0.12–0.84]), lower incidence of HPV 6, 11, 16, 39 and 61 (IRRs: 0.34 [0.13–0.90], 0.26 [0.08–0.87], 0.44 [0.21–0.91], 0.21 [0.05–0.93], and 0.19 [0.04–0.82], respectively), as well as higher clearance of HPV 52 (CRR: 2.17 [1.08–4.35]) after PrEP initiation. PrEP use may lower the risk of HPV infection among MSM in Xinjiang, China. Our findings further extend the knowledge of the impact of PrEP on sexually transmitted infections. [ABSTRACT FROM AUTHOR]

Introduction: Pre-exposure prophylaxis (PrEP) persistence among men who have sex with men (MSM) in real world clinical settings for HIV prevention is suboptimal. New longer-acting formulations of PrEP are becoming available, including injectables, subdermal implants, and other oral medications. These longer-acting formulations have the potential to improve retention among those who have challenges remaining adherent to daily oral PrEP. Methods: We interviewed 49 MSM who had initiated but discontinued oral PrEP at three diverse clinics across the United States. We examined participants’ perspectives about long-acting PrEP formulations and how long-acting options could affect PrEP use using thematic analysis. Results: Participants were not very knowledgeable about long-acting formulations of PrEP but were open to learning about them and considering use. Participants were concerned about safety and efficacy of products given that they were still newer and/or in development. Finally, participants had clear preferences for oral pills, injectables, and then subdermal implants and were most interested in options that reduced the number of visits to the clinic. Conclusion: Long-acting formulations of PrEP are acceptable to MSM with suboptimal PrEP persistence and have the potential to improve PrEP persistence. However, many felt they needed more information on safety, efficacy, and use to consider these options. As these long-acting formulations are implemented, public health campaigns and clinical interventions to encourage may maximize uptake particularly among those who are not currently adherent to daily oral PrEP.

Introduction: There are no data on community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) infections in the context of the chemsex phenomenon. This study aimed to characterize CA-MRSA-related infections in a cohort of people living with HIV (PLWH) who engage in chemsex. Methods: At the Hospital Clinic of Barcelona, from February 2018 to January 2022, we analyzed CA-MRSA infections diagnosed in a cohort of PLWH who engage in chemsex. Epidemiological, behavioral and clinical variables were assessed. Mass spectrometry identification and antimicrobial susceptibility testing were performed on MRSA isolates. Pulse field electrophoresis was used to assess the clonality of the MRSA strains. The presence of Panton-Valentine leukocidin was also investigated. Results: Among the cohort of 299 participants who engage in chemsex, 25 (8%) with CA-MRSA infections were identified, 9 at baseline and 16 with incident cases; the cumulative incidence was 5.5% (95% CI: 3.2%, 8.8%). The most common drugs were methamphetamine (96%) and GHB/GBL (92%). Poly-consumption and slamming were reported by 32% and 46%, respectively. CA-MRSA was isolated from the infection sites of 20 participants, and CA-MRSA colonization was confirmed in the remaining 5 persons. Seventy-one percent had used antibiotics in the previous year. All participants presented with skin and soft tissue infections, 28% required hospitalization, and 48% had recurrence. Of the 23 MRSA isolates further studied, 19 (82,6%) belonged to the same clone. Panton-Valentine leukocidin was detected in all isolates. Conclusion: PLWH who engage in chemsex may present with CA-MRSA infections. Clinical suspicion and microbiological diagnosis are required to provide adequate therapy, and CA-MRSA prevention interventions should be designed. [ABSTRACT FROM AUTHOR]

Treating marginalized populations with HCV infection for elimination is faced with the challenge for the integration of HCV screening service offered for patients often moving across multiple settings. We envisaged a novel collaborative care approach to identify to what extent HCV patients overlapped between and within these multiple institutions and reported the findings of treatment coverage of these marginalized populations after HCV care cascades. We enrolled 7765 patients residing in the Changhua County, Taiwan offered with HCV screening from correctional institutions, HIV clinics, methadone clinics, and the existing HIV surveillance program (four subgroups including police-arrested people, probationers, non-injection drug user, and high-risk behavior people) between 2019 and 2020. The collaborative care and information were integrated through a teamwork of gastroenterologists, psychologists, infectious disease specialists, and nursing coordinators under the auspices of local health authority. The overall participation rate in HCV screening was 92.65% (7194/7765). The prevalence rate was the highest in methadone clinics (90.17%) followed by correctional institutions (37.67%), HIV clinics (34.60%), and the surveillance program (18.14%). We found 25.41% (77/303) of methadone clinic patients, 17.65% (129/731) of HIV clinic patients, and various proportions for 44.09% (41/93) of deferred prosecuted or probationers under surveillance program were also recruited into other settings. Individuals' patient flow within setting was more frequent than that between setting. After calibrating the overlap of patient flow, a total of 1700 anti-HCV positives out of 4074 after screening were traced with available follow-up information to complete 92.52% treatment coverage of 1177 RNA-positives (77.23%) diagnosed from 1524 undergoing RNA testing with similar findings across multiple settings. A new collaborative integrated care was adopted for elucidating patient flow between and within multiple settings in order to calibrate the accurate demand for HCV care cascades and enhance HCV treatment coverage in marginalized populations.

This study aims to identify the factors that are associated with homonegativity toward men who have sex with men (MSM) within Black communities since the expansion of LGBTQ rights. A survey was completed in 2016 by a nationally representative sample of 868 Black respondents, 18–50 years old, via e-mail. Demographics, perception of same-gender sexual behaviors, religiosity, experienced racism, and contact with the carceral system (CS) were assessed. 61.6% of respondents endorsed at least one homonegative belief. Being male, residing in the South, attending religious services, receiving homonegative faith messaging, and having contact with the CS were significantly associated with homonegativity toward MSM while experiencing racism, older age, and residing in a non-metropolitan area were not. Education efforts on LGBTQ identities in Black communities should engage faith communities, extend to metropolitan and non-metropolitan areas of the South, and include younger and older adults. Programs that decrease the arrest of Black individuals may also help reduce homonegativity toward MSM. [ABSTRACT FROM AUTHOR]

Abstract Background Gonorrhoea is an ongoing public health concern due to its rising incidence and the emergence of antibiotic resistance. There are an estimated 82 million new Neisseria gonorrhoeae infections each year, with several populations at higher risk for gonococcal infection, including gay and bisexual men (GBM). If left untreated, infection can lead to serious morbidity including infertility, sepsis and increased risk of HIV acquisition. Development of a gonorrhoea vaccine has been challenging, however there is observational evidence that serogroup B meningococcal vaccines, used to protect against the closely related bacteria Neisseria meningitidis, could provide cross-protection against N. gonorrhoeae. Methods The MenGO (Meningococcal vaccine efficacy against Gonorrhoea) study is a phase III open-label randomised control trial in GBM to evaluate the efficacy of the four-component meningococcal serogroup B vaccine, 4CMenB, against gonorrhoea. A total of 130 GBM will be recruited at the Gold Coast Sexual Health Clinic, Australia, and randomised to either receive 2 doses of 4CMenB or no intervention. Participants will be followed up for 24 months with testing for N. gonorrhoeae and other sexually transmissible infections every three months. Demographics, sexual behaviour risk, antibiotic use, and blood samples for analysis of N. gonorrhoeae-specific immune responses, will be collected during the study. The primary outcome is the number of N. gonorrhoeae infections in participants over 2 years measured by nucleic acid amplification test (NAAT). Secondary outcomes are vaccine-induced N. gonorrhoeae-specific immune responses, and adverse events in trial participants. Discussion This trial will determine if the 4CMenB vaccine is able to reduce N. gonorrhoeae infection. If shown to be effective, 4CMenB could be used in gonococcal prevention. Analysis of 4CMenB-induced immune responses will increase understanding of the type of immune response needed to prevent N. gonorrhoeae, which may enable identification of a potential correlate of protection to aid future gonorrhoea vaccine development. Trial registration The trial has been registered on the Australian and New Zealand Clinical Trials Registry (ACTRN12619001478101) on 25 October 2019.

Background: World Health Organization (WHO) reported that there are 6 million new cases of syphilis worldwide per year. The incidence of syphilis in Indonesia has increased over the past few years, particularly among men who have sex with men (MSM). Purpose: To report a case of secondary syphilis with Human Immunodeficiency Virus (HIV) coinfection in MSM, thereby increasing understanding of high-risk sexual behavior among MSM. Case: A 26-year-old man with a chief complaint of rashes on both palms, soles of the feet, and face. The rashes spread with no itching, heat, or pain, which occurred two weeks ago. The patient was diagnosed with HIV in 2019. Physical examination found multiple violaceus macules with clear boundaries, 0.5–1 cm in size, covered with scales. Venereal Disease Research Laboratory (VDRL) serology titer was 1:16 and Treponema Pallidum Haemagglutination Assay (TPHA) was 1:20.480. The recent CD4 count was 440 with an undetectable HIV RNA viral load. Benzathine penicillin G 2.4 million units was given intramuscularly 3 times at 1-week intervals. The patient experienced clinical improvement and decreased VDRL and TPHA titers. Discussion: Syphilis patients with or without HIV would have similar clinical symptoms. However, syphilis patients with HIV tend to have more extensive lesions. The treatment option with three doses of benzathine penicillin G is still very effective in cases of syphilis with HIV. Conclusion: Syphilis has a higher incidence in MSM patients with extensive clinical manifestations of skin lesions. It can be observed in syphilis patients with HIV; therefore, close monitoring is needed.

Background: Men with sex with men (MSM) may face obstacles in accessing culturally competent and quality healthcare services since current medical practice does not often promote discussing sexual habits. The coronavirus disease-2019 (COVID-19) pandemic has further affected this group. This study assessed the impacts of COVID-19 and the general challenges of MSM in Benue State, Nigeria. Materials and Methods: This study was a quantitative cross-sectional survey conducted across three geopolitical zones of Benue State using a multistage cluster sampling method to collect data from MSM. The data collected were analyzed using IBM-Statistical Package for Social Sciences (IBM-SPSS) version 25.0 for Windows IBM Corp., Armonk, New York. Result: More than half (59.2%) of respondents said they were not denied healthcare services, and 78.4% were not afraid to seek them. Most (88%) were comfortable seeking medical help, and 61.6% did not experience stigmatization from healthcare providers. Many (68.0%) were not exposed to violence after sharing their status with healthcare providers. About half (50.4%) said COVID-19 did not affect their general quality of life. Over half (51.2%) said there was a decline in access to resources like food and money during the pandemic, 49.6% experienced difficulties accessing HIV testing, and 52.0% could not access PrEP. More than half (53.6%) reported challenges getting viral load or other laboratory tests, but 57.5% had no trouble getting HIV medication prescriptions. Conclusion: The Federal Government, and the Ministry of Health, Nigeria, should support intervention programs, peer educators, and outreach workers providing services to MSM.

Abstract Background New HIV infections in the Philippines are increasing at an alarming rate. However, over three quarters of men who have sex with men (MSM) have never been tested for HIV. HIV self-testing (HIVST) may increase overall testing rates by removing barriers, particularly fear of stigmatization and mistrust of providers. This study aimed to determine if these factors are associated with preference for HIVST among Filipino cisgender MSM (cis-MSM), and whether there is an interaction between anticipated HIV testing stigma and provider mistrust on preference for HIVST. Methods We conducted secondary analysis of a one-time survey of 803 cis-MSM who were recruited using purposive sampling from online MSM dating sites and MSM-themed bar locations in Metro Manila, Philippines. Summary statistics were computed to describe participant characteristics. Multivariable modified Poisson regression analyses were conducted to determine if anticipated HIV testing stigma and provider mistrust were associated with preference for HIVST among cis-MSM. Other variables such as age, education, monthly income, relationship status, HIV serostatus, and knowing where to get HIV testing were the minimal sufficient adjustment set in the analyses. Results Average age of participants was 28.6 years (SD = 8.0); most had received college degrees (73%) and were employed (80%). Most respondents (81%) preferred facility-based testing, while 19% preferred HIVST. A high percentage of participants reported anticipated HIV testing stigma (66%) and provider mistrust (44%). Anticipated HIV testing stigma (aPR = 1.51; 95% CI = 1.01–2.25, p = 0.046) and provider mistrust (aPR = 1.49; 95% CI = 1.07–2.09, p = 0.020) were independently associated with a preference for HIVST. There was a positive, additive interaction between provider mistrust and anticipated HIV testing stigma on preference for HIVST (RERI = 1.13, 95% CI: 0.20–2.06; p = 0.017), indicating that the association between anticipated HIV testing stigma and preference for HIVST is greater among those with provider mistrust compared to those without provider mistrust. Conclusions HIVST should be offered as a supplement to traditional facility-based HIV testing services in the Philippines to expand testing and reach individuals who may not undergo testing due to anticipated HIV testing stigma and provider mistrust.

Introduction: The health and economic benefits of human papillomavirus (HPV) vaccination targeted at men who have sex with men (MSM) in developing settings have been rarely assessed. This study aimed to evaluate the effectiveness and cost-effectiveness of different HPV vaccination strategies among MSM in China. Methods: A Markov model was developed to simulate HPV transmission dynamics among a total of 30.73 million MSM in China. The corresponding natural history included 6 states: susceptible, infected with low-risk subtypes, high-risk subtypes, anogenital warts and anal cancer, and deaths from anal cancer. MSM were divided into three age groups with cut-off points of 27 and 45 years. Alternative vaccination strategies were built by allocating bivalent, quadrivalent, nine-valent, or no vaccine to each of the groups. We generated the prevented infections and deaths by vaccination compared with baseline (no vaccination) and calculated incremental cost-effectiveness ratios (ICERs) to determine the optimal strategy. Results: The model showed that in 10 years, at baseline, the existing cases of anogenital warts would reach 5,464,225 (IQR, 4,685,708-6,174,175); that of anal cancer would reach 1,922.95 (1,716.56-2,119.93), resulting in 940.55 (732.27-1,141.87) deaths. Under 50% vaccination coverage among one age group, the prevented cases of anogenital warts were maximized with quadrivalent vaccines allocated to MSM aged 27-45 years; that of anal cancer were maximized when offering nine-valent vaccines to the same group. Under 50% vaccination coverage among all groups, the lowest ICER (34,098.09 USD/QALY, 31,146.54-37,062.88) was reached when only quadrivalent vaccines were provided. Based on this strategy, when the annual vaccination rate increased by 30%, the ICER (33,521.75 USD/QALY, 31,040.73-36,013.92) would fall below three times China's per capita GDP. When the vaccine price decreased by 60%, the ICER was reduced to 7,344.44 USD/QALY (4,392.89-10,309.23), indicating good costeffectiveness taking China's per capita GDP as a threshold. Conclusions: HPV vaccination can effectively reduce the prevalence and mortality of related diseases among MSM in China, especially quadrivalent vaccines for anogenital warts and nine-valent vaccines for anal cancer. MSM aged 27-45 years were the optimal group for vaccination. Annual vaccination and appropriate adjustment of vaccine price are necessary to further improve the cost-effectiveness.

Syphilis testing uptake is low among men who have sex with men (MSM) around the world. Syphilis self-testing (SST) may complement facility-based testing; the distribution model is yet to be explored. This study aimed to investigate the effectiveness of peer distribution of syphilis self-testing on promoting syphilis testing. We conducted a three-arm, unblinded, parallel individually randomized controlled trial among MSM in three cities in Guangdong, China. Inclusion criteria were: men who were born biologically male, aged 18 or above, have ever had sex with a man, will refer the interventions to peers, and will take the three-month follow-up survey. Enrolled indexes were randomly assigned in a 1:1:1 ratio into standard-of-care arm (SOC arm), standard SST delivery arm (S-SST arm), and a web-based referral link SST delivery arm (RL-SST arm). The primary outcome was the number of returned photograph-verified syphilis testing results per index. A total number of 300 indexes were enrolled, with 100 indexes in each arm. The number of verified syphilis tests per index conducted by alters was 0.05 in the control arm, 0.51 in the S-SST arm, and 0.31 in the RL-SST arm. The cost per alter tested was $760.60 for SOC, $83.78 for S-SST, and $93.10 for RL-SST. Minimal adverse event was reported among both indexes and alters during the study. This study showed that peer distribution of SST could improve syphilis testing uptake among MSM in China compared to facility-based testing. This approach warrants further consideration as part of expanding syphilis self-testing. [ABSTRACT FROM AUTHOR]

HIV incidence is disproportionately high among young cisgender men who have sex with men (YMSM), but YMSM are less likely than adults to use HIV pre-exposure prophylaxis (PrEP). Among YMSM living with HIV, peer navigation programs have been effective in linkage to care and increasing medication adherence; such programs may aid HIV-uninfected YMSM in overcoming barriers to engagement in PrEP care. We conducted 32 semi-structured qualitative interviews at a community health center in Massachusetts, USA, specializing in sexual and gender minority health with four sub-groups of YMSM who: (1) had never discussed PrEP with a medical provider, (2) had discussed PrEP with a medical provider but declined a prescription, (3) were prescribed PrEP and have sub-optimal adherence (taking fewer than 4 pills per week), and (4) were prescribed PrEP and were optimally adherent. Domains addressed in the interviews included knowledge of PrEP and HIV prevention, barriers and facilitators to PrEP adherence, and attitudes toward peer navigation for PrEP. Interviews were transcribed and coded using thematic analysis methodology. Multiple themes emerged from the interviews, including finding that perceived costs, anticipated stigma, sexual activity, and relationship status influence PrEP uptake and adherence; establishing pill-taking routines is an important adherence facilitator; and peer navigators could offer benefits for PrEP adherence.
