Background: Preexposure prophylaxis (PrEP) is an effective biological option for HIV prevention yet persistent disparities in PrEP uptake and retention exist among Hispanic/Latino men who have sex with men (MSM). We evaluated barriers and facilitators to PrEP care among Hispanic/Latino MSM at risk for and living with HIV., Setting: A small urban setting in the Northeastern United States., Methods: This was a mixed-methods, exploratory, sequential, qualitative and quantitative pilot study among Latino MSM at-risk and/or living with HIV across (1) semistructured qualitative interviews (N = 15) and (2) cross-sectional survey (N = 98)., Results: Participants reported a diverse range of sexual identities, HIV statuses, and PrEP statuses. Qualitative participants described feelings of isolation in both Hispanic/Latino and queer communities that made it challenging to learn about HIV prevention or PrEP from peers. Participants in the survey indicated that they would be more inclined to uptake PrEP if PrEP were offered in primary care settings (n = 61; 62.2%); there were specific LGBTQ+ affirming medical settings (n = 36; 36.7%); and/or they could meet other people who are currently on PrEP and sharing experiences online (n = 46; 46.9%) or in person (n = 38; 38.8%). Findings were organized to reflect determinants and implementation strategies that could be used to improve PrEP uptake among this population., Conclusions: This mixed-methods study identified several challenges and opportunities for increasing the reach of PrEP to Hispanic/Latino MSM. These findings should be used to inform tailored implementation strategies to promote PrEP uptake among this at-risk yet currently underserved population., Competing Interests: Dr. B.G.R. received funding in the form of a Developmental Research Award from the Providence/Boston Center for AIDS Research to conduct this project (P30AI042853).

Men who have sex with men (MSM) are at high risk of acquiring hepatitis A virus (HAV) and in recent years several HAV outbreaks mostly affecting MSM have been described. These outbreaks were caused by subtype IA strains circulating in this high-risk population. After years of low incidence, an outbreak among MSM in Hungary caused a significant increase in reported HAV infections in 2022. Samples from 224 HAV IgM-positive patients diagnosed in 2022 were tested for HAV RNA and positive samples were genotyped by sequencing. In 171 patients a unique subtype IB virus was detected with 99.8-100% sequence identity in the VP1/P2A junction. It was distinct from previously published strains, but most closely related to an Egyptian isolate. Sequence analysis revealed one dominant and three minor variants based on VP1/P2A. Whole genome sequencing revealed limited variation among these variants, suggesting a recent common origin. Epidemiological data indicated that sexual transmission was driving the outbreak for most of the year, suggested by the high male to female ratio and the large number of coinfections with HIV and other sexually transmitted infections among the patients. The outbreak was also associated with a restaurant cluster, in which one of the variants was detected and frozen berries were implicated as the source of infections. The outbreak strain was also detected in other countries around Europe and remained frequently detectable in Hungary in 2023. This study provides insights into the molecular and epidemiological characteristics of the described HAV outbreak. The results show that sequencing is not only useful in connecting cases to an outbreak, but also helps to clarify the relatedness of detected variants. Prevention strategies focusing on vulnerable communities may reduce the burden of HAV infections in the future., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

Background: Men who have sex with men (MSM) are more vulnerable to acquiring sexually transmitted infections (STIs). In 2019, for instance, 74% of European Neisseria gonorrhoeae (Ng) cases among males affected MSM. A recent report by the World Health Organization showed that most of the 2020' interim targets to end STIs by 2030 had not been met. A broadened understanding of STI transmission networks could guide future elimination strategies and reduce the STI burden. Therefore, we used whole-genome sequencing (WGS) to determine Ng-clusters and assess sexual mixing., Methods: WGS was performed on Ng-isolates collected at the Medical University of Vienna, Austria and was used for core genome multi-locus sequencing typing cluster analysis. Epidemiologic and infection-specific details were extracted from medical records., Results: Genomic analysis and demographic data were available for 415 isolates, and 43.9% (182/415) were allocated to 31 Ng-clusters. Nine clusters comprised samples from heterosexual individuals only (women N  = 4, human immunodeficiency virus (HIV)-negative men N  = 49, HIV-positive man N  = 1), nine clusters included MSM only (HIV-negative N  = 22, HIV-positive N  = 13) and 13 clusters included both heterosexuals and MSM (HIV-negative N  = 75, HIV-positive N  = 18). Current use of HIV pre-exposure prophylaxis (PrEP) was reported by 22.8% of MSM. In multivariate analysis, only 'MSM' predicted clustering with isolates from HIV-positive individuals (adjusted odds ratio 10.24 (95% CI 5.02-20.90))., Conclusions: Sexual mixing of HIV-positive, HIV-negative MSM and non-MSM was frequently observed. Furthermore, HIV-serodiscordant clustering highlights the importance of PrEP rollout to avert HIV transmission. Our findings can inform future STI prevention strategies and continuous surveillance efforts are required to keep up with transmission dynamics.

Objective.: To analyze the elements of a navigation program in Lima that facilitated the linkage of men who have sex with men (MSM) and transgender women (TW) with HIV care., Material and Methods.: We conducted interviews with 20 users receiving navigation services and 4 peer navigators living with HIV., Results.: The work of the navigators contributed to filling a gap in HIV services, providing personalized accompaniment to navigate the health care system and facilitating the process of engaging with care., Conclusions.: Patient navigation based on the development of users' strengths can be a useful and feasible strategy to improve linkage to medical care for MSM and TW in Peru, incorporating peer navigators to health teams, horizontality in treatment and public health strategies with greater community participation., Motivation for the study. In Peru, men who have sex with men (MSM) and transgender women (TW) present low levels of linkage to HIV medical care, which is crucial to consider it a chronic disease, guarantee a healthy life and prevent transmission. Main findings. We implemented a program with specialized personnel called peer navigators, which helped MSM and TW to identify personal strengths and become autonomous within a fragmented and unfriendly health system. Implications. Incorporating peer navigators is a useful and feasible strategy that contributed to filling a gap in HIV care services, providing accompaniment, education and horizontal treatment to improve linkage to medical care for MSM and TW.

Objectives: Doxycycline as post-exposure prophylaxis (DoxyPEP) is a novel prevention approach which has demonstrated efficacy in preventing bacterial sexually transmitted infections (STIs) in men who have sex with men (MSM) and transgender women (TGW) including people who are living with HIV and those on HIV pre-exposure prophylaxis (PrEP). We evaluated patient knowledge and interest in DoxyPEP, as well as early adopters of its use., Methods: In 2023, patients presenting for HIV and STI services at a primary care and sexual health clinic were asked about DoxyPEP knowledge, interest and use. Bivariate and multivariate analyses were used to evaluate demographics and behaviours associated with these outcomes., Results: A total of n=421 people presented for care. Of these, 314 were MSM/TGW. Fifteen percent were Black/African-American, and 21% were Hispanic/Latino. A total of 50% of MSM/TGW had heard of DoxyPEP, 49% were interested and 18% reported prior DoxyPEP use. Having a history of STI infection ever (adjusted OR (aOR) 5.95, 95% CI 2.69 to 13.13) and in the past 12 months (aOR 2.99, 95% CI 1.56 to 5.72) were both associated with DoxyPEP use. Individuals who had ever used HIV PrEP had nearly three times the odds of ever taking DoxyPEP (aOR 2.88, 95% CI 1.56 to 5.30). There was no association between the use of DoxyPEP and race, ethnicity or HIV status., Conclusions: Among MSM and TGW, there is already significant awareness, interest and use of DoxyPEP to prevent bacterial STIs. Public health efforts should focus on improving access and delivery of this STI prevention intervention to MSM and TGW., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Background: Anal cancer is caused by human papillomavirus (HPV), particularly HPV-16, and is preceded by anal high-grade squamous intraepithelial lesions (HSILs). The incidence of anal cancer is highest among men who have sex with men (MSM) living with HIV (MSMLWH) and increases with age. However, most previous studies of anal HPV infection and anal HSIL were performed on men under 50 years old, and relatively little is known about HSIL among older MSMLWH or MSM not living with HIV (MSM-Not-LWH)., Setting: We enrolled MSM who were aged 50+ during 2018-2022 in San Francisco, CA., Methods: One hundred twenty-nine MSMLWH and 109 MSM-not-LWH participated. All participants had anal HPV DNA testing (Atila Biosystems) and high-resolution anoscopy with a biopsy of visible lesions., Results: Among MSMLWH, 47% had anal HSIL, 19% had HPV-16, and 51% had other oncogenic anal HPV types (excluding HPV-16). Among MSM-not-LWH, 37% had anal HSIL, 22% had HPV-16, and 34% had other oncogenic anal HPV types. Increasing age was not statistically associated with prevalent HSIL, HPV-16, or other oncogenic HPV infections in MSMLWH or MSM-not-LWH. HPV-16 (odds ratio: 45.1, 95% confidence interval: 15.8-129); other oncogenic HPV types (odds ratio: 5.95, 95% confidence interval: 2.74-12.9) were associated with increased odds of anal HSIL, adjusted for age, income, education, and HIV status., Conclusion: The prevalence of oncogenic anal HPV, anal HPV-16, and anal HSIL remains very high in older MSMLWH and MSM-not-LWH. With recent evidence showing that treating anal HSIL prevents anal cancer, MSM aged 50+ should be considered for anal cancer screening., Competing Interests: The authors have no funding or conflicts of interest to disclose., (Copyright © 2024 Wolters Kluwer Health, Inc.

Using a comprehensive molecular epidemiological approach, we characterized the transmission dynamics of HIV-1 among the MSM population in Tianjin, China. Our findings revealed that 38.56% (386/1001) of individuals clustered across 109 molecular transmission clusters (TCs), with MSM aged 50 and below being the group most commonly transmitting HIV-1. Among the identified TCs, CRF01_AE predominated, followed by CRF07_BC. Notably, CRF07_BC demonstrated a higher propensity for forming large clusters compared to CRF01_AE. Birth-death skyline analyses of the two largest clusters indicated that the HIV/AIDS transmission may be at a critical point, nearly all had Re approximately 1 by now. A retrospective analysis revealed that the rapid expansion of these large clusters was primarily driven by the introduction of viruses in 2021, highlighting the crucial importance of continuous molecular surveillance in identifying newly emerging high-risk transmission chains and adapting measures to address evolving epidemic dynamics. Furthermore, we detected the transmission of drug-resistant mutations (DRMs) within the TCs, particularly in the CRF07_BC clusters (K103N, Y181C, and K101E) and CRF01_AE clusters (P225H and K219R), emphasizing the importance of monitoring to support the continued efficacy of first-line therapies and pre-exposure prophylaxis (PrEP). Recombination analyses indicated that complex recombinant patterns, associated with increased amino acid variability, could confer adaptive traits to the viruses, potentially providing a competitive advantage in certain host populations or regions. Our study highlights the potential of integrating molecular epidemiological and phylodynamic approaches to inform targeted interventions., (© 2024 Wiley Periodicals LLC.)

Background: Shigellosis is diarrheal disease caused by highly infectious Shigella bacteria. Shigella can spread in multiple ways, including sexual contact. Gay, bisexual, and other men who have sex with men are particularly at risk for shigellosis., Methods: To evaluate the acceptability of 3 Centers for Disease Control and Prevention-developed behavioral recommendations for the prevention of sexually transmitted shigellosis, virtual in-depth interviews were conducted among 26 gay or bisexual men in March to May 2021., Results: Participants had a median age of 25 years; 65% were non-Hispanic White, 12% were Hispanic White, 12% Asian, 4% Hispanic Black, and 8% multiracial/other. Respondents indicated willingness to engage in certain prevention behaviors (e.g., washing hands, genitals, and anus before and after sex), but were less willing to engage in behaviors that were viewed as outside social norms or difficult to practice (e.g., dental dams for oral-anal contact; latex gloves for fingering or fisting). Respondents thought recommendations may be more feasible if knowledge of shigellosis was greater; however, some perceived that the severity of shigellosis is low and did not warrant the effort of engaging in prevention behaviors., Conclusions: Educational efforts to increase awareness of shigellosis and other enteric diseases spread through sexual contact are needed and public health practitioners should consider the acceptability of how realistic it is for individuals to engage in certain prevention behaviors. Rather than recommending behaviors that do not have buy-in, it may be more efficacious to focus recommendations on adopting behaviors reported as acceptable to the target audience., Competing Interests: Conflicts of Interest and Source of Funding: None declared., (Copyright © 2024 American Sexually Transmitted Diseases Association.

Objectives: This study aimed to assess associations of potential risk factors with human papillomavirus (HPV) seropositivity among men who have sex with men (MSM) and compare these to risk factors for anal and penile (HPV) deoxyribonucleic acid (DNA)-positivity in the same study population., Methods: Seropositivity and anal and penile HPV DNA-positivity were determined for seven high-risk HPV genotypes for MSM aged 16-24 years participating in Papillomavirus Surveillance among STI clinic Youngsters in the Netherlands (PASSYON) 2009-2021. Logistic regression models were conducted to assess risk factors for seropositivity, anal and penile HPV DNA-positivity., Results: Overall, 1019 MSM were included. HPV-16 and -18 were most common for serology, and anal and penile HPV DNA-positivity. Although no clear similarities were observed for most risk factors for HPV seropositivity and anal or penile DNA positivity, receptive anal intercourse (RAI) was the strongest associated risk factor for both seropositivity ('RAI ever' adjusted odds ratio [aOR] 3.50, 95% confidence interval [CI] 1.56-7.88; 'RAI previous 6 months' aOR 2.17, 95% CI 1.44-3.26) and anal DNA-positivity ('RAI previous 6 months' aOR 1.67, 95% CI 1.09-2.56)., Conclusions: Our study is suggestive of site-specific immune response after HPV infection; RAI might lead to anal HPV infections and consequently to seroconversion. Finally, as the two genotypes that are most oncogenic and preventable by all HPV vaccines were most common, our results underline the importance of gender-neutral vaccination., Competing Interests: Declarations of competing interests The institution of M.

Background: Home-based sampling could create accessible testing opportunities for men who have sex with men (MSM) who use pre-exposure prophylaxis (PrEP). Blood collection is required for the most reliable laboratory results for HIV and syphilis testing. An innovative blood collection method (Tasso+) creates a vacuum and semi-automatically collects larger volumes of blood from the upper arm. This study aimed to assess acceptability and feasibility of this device among PrEP-using MSM and the performance of blood collection., Methods: Between August 2022 and January 2023, 47 MSM were recruited during their routine PrEP consultations at a Dutch Centre for Sexual Health. Participants tested the method directly after consultation, and an online questionnaire determined acceptability and feasibility. Blood and residual serum volumes were measured after sampling and after HIV and syphilis testing., Results: Of the participants, 87% had a positive attitude toward use of the device, and 77% would use it again for self-sampling at home. Participants rated the use of the blood collection device as easy (96%). On average, 536 μL whole blood (244 μL serum) was collected. All samples were tested for HIV and syphilis, and most samples had sufficient blood for routine HIV (91%) and syphilis testing (89%). Most samples (85%) had 220 μL residual blood, sufficient for further testing (e.g., confirmation)., Conclusions: Blood self-sampling with a method that creates a vacuum from the upper arm is highly acceptable by users and performs well in blood collection for multiple tests. This method has promising potential for use in home-based sexual health care for PrEP-using MSM., Competing Interests: Conflict of Interest and Sources of Funding: None declared., (Copyright © 2024 The Author(s).

Background: Associations of sleep deficiency and methamphetamine use with sexual health and HIV treatment outcomes are poorly understood., Setting: A longitudinal cohort of men who have sex with men at risk for or living with HIV (the mSTUDY) was analyzed. This analysis included 1445 study visits among 382 participants. Data were collected from June 2018 to February 2022., Methods: Semiannual study visits included self-interviews for sleep deficiency, sexual behaviors, substance use, and HIV treatment. Sleep deficiency was measured using the Pittsburgh Sleep Quality Index. Participants provided specimens for HIV viral load and sexually transmitted infection (STI) testing (chlamydia, gonorrhea, syphilis). Associations between sleep deficiency and STI/HIV outcomes were estimated using multiple logistic regression., Results: Across visits, the prevalence of sleep deficiency was 56%, with 33% reporting methamphetamine use and 55% living with HIV. Sleep deficiency was associated with reporting at least 1 new anal sex partner (aOR = 1.62, 95% CI: 1.21 to 2.15), exchange sex (aOR = 2.71, 95% CI: 1.15 to 6.39), sex party attendance (aOR = 2.60, 95% CI: 1.68 to 4.04), and missing HIV medications (aOR = 1.91, 95% CI: 1.16 to 3.14). The association between sleep deficiency and exchange sex differed for participants who did and did not report the use of methamphetamine (P = 0.09)., Conclusion: Sleep deficiency was associated with sexual health and HIV treatment behaviors after accounting for methamphetamine use. Sleep health should be considered in STI/HIV prevention, particularly for those who use methamphetamine., Competing Interests: The authors have no funding or conflicts of interest to disclose., (Copyright © 2024 Wolters Kluwer Health, Inc.

Objectives: Anal cancer risk is elevated in MSM with HIV (MSMWH). Anal high-risk human papillomavirus (hr-HPV) infection is necessary but insufficient to develop high-grade squamous intraepithelial lesion (HSIL), the anal cancer precursor, suggesting additional factors. We sought to determine whether the microbiome of the anal canal is distinct by comparing it with the microbiome of stool. We also sought to determine whether changes in the anal microbiome are associated with HSIL among MSMWH., Design: Cross-sectional comparison of the microbiome of the anal canal with the microbiome of stool in MSMWH and cross-sectional comparison of the anal microbiome of MSMWH with anal HSIL with the anal microbiome of MSMWH without anal HSIL., Methods: Sterile swabs were used to sample the anus of MSMWH for microbiome and HPV testing, followed by high-resolution anoscopy. Stool samples were mailed from home. 16S sequencing was used for bacterial identification. Measures of alpha diversity, beta diversity, and differential abundance analysis were used to compare samples., Results: One hundred sixty-six anal samples and 103 matching stool samples were sequenced. Beta diversity showed clustering of stool and anal samples. Of hr-HPV-positive MSMWH, 31 had HSIL and 13 had no SIL. Comparison of the microbiome between these revealed 28 different species. The highest-fold enrichment among MSMWH/hr-HPV/HSIL included pro-inflammatory and carcinogenic Prevotella, Parasuterella, Hungatella, Sneathia, and Fusobacterium species. The anti-inflammatory Anaerostipes caccae showed the greatest reduction among MSMWH/hr-HPV/HSIL., Conclusion: The anal microbiome is distinct from stool. A pro-inflammatory and carcinogenic environment may be associated with anal HSIL., (Copyright © 2024 The Author(s). Published by Wolters Kluwer Health, Inc.)

In China, the proportion of HIV-1 infections due to men who have sex with men (MSM) has increased rapidly. More and more new subtypes are found among the MSM population besides known CRF01_AE, CRF07_BC, and B. The co-circulation of several HIV subtypes in the same population provides the opportunity to develop a new circulating recombinant form (CRF) and unique recombinant form (URF). Here we reported two new URFs from two HIV-1 positive subjects infected through homosexual contact in Hebei, China. Phylogenetic and recombinant analyses based on the near full-length genome (NFLG) of the two URFs are the second-generation recombinant strains that originated from B, CRF01_AE, and CRF07_BC. The CRF01_AE segments in the genome of two URFs originated from cluster 4 of CRF01_AE strains, while the CRF07_BC segments were clustered with 07BC_N in the phylogenetic tree. The emergence of the novel CRF01_AE/CRF07_BC and CRF01_AE/B recombinant forms indicated the importance of the continuous monitoring of the HIV-1 epidemic and new URFs among the MSM population.

In this article, I consider a selection of photographs of a man of color from a luxury book of male nudes, Images (1982), aimed at white gay men and published in South Africa by Alternative Books (AB) in the late apartheid period. Given the exclusive association of assimilable homosexuality with whiteness in the national gay press and other homoerotic commodities available in South Africa at the same historical juncture, I propose that these photographs, which interrupted longstanding, racist homoerotic iconographies, elicited experiences of ambivalence (and thus critical reflection) amongst their historical audiences. To this end, I analyze the editorial and commercial content of the newspapers Link/Skakel and Exit for the period that AB was active (1981-1991), anticipating an overlap of readership between these papers and the publisher's titles. More precisely, I discuss the prevalence of the figure of the "good homosexual" and representations of classical (that is, white) male beauty in these papers to plot how apartheid logic was broadly reproduced (and same-sex desire disciplined according to such dictates) in mainstream South African gay movements, institutions, and print cultures during this time, but, notably, not in Images .

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., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Background: In the Netherlands, the number of mpox cases started declining before mpox vaccination was initiated. Most cases were men who have sex with men (MSM). We investigated whether the decline in mpox could be attributed to infection-induced immunity or behavioral adaptations., Methods: We developed a transmission model and accounted for possible behavioral adaptations: fewer casual partners and shorter time until MSM with mpox refrain from sexual contacts., Results: Without behavioral adaptations, the peak in modelled cases matched observations, but the decline was less steep than observed. With behavioral adaptations in the model, we found a decline of 16%-18% in numbers of casual partners in June and 13%-22% in July 2022. Model results showed a halving of the time before refraining from sex. When mpox vaccination started, 57% of MSM with very high sexual activity in the model had been infected. Model scenarios revealed that the outbreak could have waned by November 2022 even without vaccination., Conclusions: The limited duration of the mpox outbreak in the Netherlands can be ascribed primarily to infection-induced immunity among MSM with high sexual activity levels. The decline was accelerated by behavioral adaptations. Immunity among those most sexually active is essential to impede mpox resurgence., Competing Interests: Potential conflicts of interest.

We assessed cumulative detection and determinants of anal high-grade squamous intraepithelial lesions (HSILs) in men who have sex with men living with human immunodeficiency virus and who underwent 3 visits over 2 years, with cytology and high-resolution anoscopy, within the ANRS-EP57-APACHES study. The cumulative HSIL detection rate was 33% (134 of 410), of which 48% HSILs were detected at baseline. HSIL detection varied considerably by center (from 13% to 51%). The strongest HSIL determinants were baseline human papillomavirus 16 (adjusted odds ratio, 8.2; 95% confidence interval, 3.6-18.9) and p16/Ki67 (4.6 [2.3-9.1]). Repeated annual cytology and high-resolution anoscopy improved HSIL detection but did not fully compensate for between-center heterogeneity., Competing Interests: Potential conflicts of interest. O.

Background: Most international treatment guidelines recommend rapid initiation of antiretroviral therapy (ART) for people newly diagnosed with human immunodeficiency virus (HIV)-1 infection, but experiences with rapid ART initiation remain limited in China. We aimed to evaluate the efficacy and safety of efavirenz (400 mg) plus lamivudine and tenofovir disoproxil fumarate (EFV + 3TC + TDF) versus coformulated bictegravir, emtricitabine, and tenofovir alafenamide (BIC/FTC/TAF) in rapid ART initiation among men who have sex with men (MSM) who have been diagnosed with HIV., Methods: This multicenter, open-label, randomized clinical trial enrolled MSM aged ≥18 years to start ART within 14 days of confirmed HIV diagnosis. The participants were randomly assigned in a 1:1 ratio to receive EFV (400 mg) + 3TC + TDF or BIC/FTC/TAF. The primary end point was viral suppression (<50 copies/mL) at 48 weeks per US Food and Drug Administration Snapshot analysis., Results: Between March 2021 and July 2022, 300 participants were enrolled; 154 were assigned to receive EFV + 3TC + TDF (EFV group) and 146 BIC/FTC/TAF (BIC group). At week 48, 118 (79.2%) and 140 (95.9%) participants in the EFV and BIC group, respectively, were retained in care with viral suppression, and 24 (16.1%) and 1 (0.7%) participant in the EFV and BIC group (P < .001), respectively, discontinued treatment because of adverse effects, death, or lost to follow-up. The median increase of CD4 count was 181 and 223 cells/μL (P = .020), respectively, for the EFV and BIC group, at week 48. The overall incidence of adverse effects was significantly higher for the EFV group (65.8% vs 37.7%, P < .001)., Conclusions: BIC/FTC/TAF was more efficacious and safer than EFV (400 mg) + 3TC + TDF for rapid ART initiation among HIV-positive MSM in China., Competing Interests: Potential conflicts of interest.

Pakistan bears a substantial burden of hepatitis C virus (HCV) infection, with the second-highest prevalence globally. This community-based cross-sectional study, conducted from January to December 2022 in Punjab, Pakistan, investigates the seroprevalence of HCV among the men who have sex with men (MSM) population. The study identifies demographic and behavioral risk factors associated with HCV infection within this population group. Among the 501 participants, the study found an HCV seroprevalence of 14.86%. The association between demographic characteristics and seroprevalence is assessed by calculating the percentage of positive cases, revealing notable associations with age, education level, and self-identified sexual orientation. Furthermore, the study identified several behavioral risk factors positively associated with HCV seroprevalence, including sharing personal items such as razors and toothbrushes, histories of surgery, blood transfusion, dental procedures, intravenous drug use, and therapeutic injection histories. These risk factors were identified through structured interviews, and the prevalence of HCV seropositivity among the exposed groups was calculated accordingly. Interestingly, a lower HCV positivity rate was observed among self-reported HIV-positive individuals, contradicting previous research. The findings underscore the need for comprehensive, targeted prevention strategies such as risk factor awareness campaigns and educational programs tailored for the MSM population in Pakistan. Further research is warranted to validate these findings and better understand the complex interplay of factors contributing to HCV seroprevalence in this high-risk population., (© 2024.

Background: Since common diagnostic tests for gonorrhea do not provide information about susceptibility to antibiotics, treatment of gonorrhea remains empiric. Antibiotics used for empiric therapy are usually changed once resistance prevalence exceeds a certain threshold (e.g., 5%). A low switch threshold is intended to increase the probability that an infection is successfully treated with the first-line antibiotic, but it could also increase the pace at which recommendations are switched to newer antibiotics. Little is known about the impact of changing the switch threshold on the incidence of gonorrhea, the rate of treatment failure, and the overall cost and quality-adjusted life-years (QALYs) associated with gonorrhea., Methods and Findings: We developed a transmission model of gonococcal infection with multiple resistant strains to project gonorrhea-associated costs and loss in QALYs under different switch thresholds among men who have sex with men (MSM) in the United States. We accounted for the costs and disutilities associated with symptoms, diagnosis, treatment, and sequelae, and combined costs and QALYs in a measure of net health benefit (NHB). Our results suggest that under a scenario where 3 antibiotics are available over the next 50 years (2 suitable for the first-line therapy of gonorrhea and 1 suitable only for the retreatment of resistant infections), changing the switch threshold between 1% and 10% does not meaningfully impact the annual number of gonorrhea cases, total costs, or total QALY losses associated with gonorrhea. However, if a new antibiotic is to become available in the future, choosing a lower switch threshold could improve the population NHB. If in addition, drug-susceptibility testing (DST) is available to inform retreatment regimens after unsuccessful first-line therapy, setting the switch threshold at 1% to 2% is expected to maximize the population NHB. A limitation of our study is that our analysis only focuses on the MSM population and does not consider the influence of interventions such as vaccine and common use of rapid drugs susceptibility tests to inform first-line therapy., Conclusions: Changing the switch threshold for first-line antibiotics may not substantially change the health and financial outcomes associated with gonorrhea. However, the switch threshold could be reduced when newer antibiotics are expected to become available soon or when in addition to future novel antibiotics, DST is also available to inform retreatment regimens., Competing Interests: T.L.G is employed by CDC; other authors declare no competing interests., (Copyright: This is an open access article, free of all copyright, and may be freely reproduced, distributed, transmitted, modified, built upon, or otherwise used by anyone for any lawful purpose.

Objective: To provide a guide on appropriate sexually transmitted infection (STI) testing for primary care providers to use with patients who identify as men who have sex with men (MSM)., Sources of Information: Canadian guidelines for STI testing and enteric and protozoan infections; Ontario guidelines for HIV screening and mpox; and US guidelines for STI testing., Main Message: Across Canada rates of sexually transmitted bacterial, enteric, protozoan, and systemic infections-including HIV and mpox-have been steadily increasing among cisgender and transgender MSM. Despite often having similar clinical presentations, these infections have different incubation periods and testing approaches and must be ruled out effectively to guide diagnosis and treatment for MSM-identifying patients who present with symptoms of various conditions. Clinical information and screening recommendations, however, are often found in multiple guidelines rather than in a single source, thus further complicating these clinical encounters. This document provides a consolidated set of evidence and recommendations for STI testing in MSM., Conclusion: Testing approaches for STIs should be comprehensive and based on the patient's reported risk factors and clinical presentation. Where ongoing STI risk is identified and negative laboratory test results are received, MSM should also be counselled on recommendations for repeat screening and HIV prevention services, such as preexposure prophylaxis., (Copyright © 2024 the College of Family Physicians of Canada.)

Introduction: Past research shows that HIV self-testing (HIVST) can increase testing and facilitate more HIV diagnoses relative to clinic testing. However, in the United States, the use of HIVSTs is limited due to concerns that those who use HIVST could be less likely to be linked to care., Methods: From January 2019 to April 2022, we recruited 811 men who have sex with men (MSM) in the United States who tested infrequently using an online marketing campaign and randomized them 1:1:1 to receive one of the following every 3 months for a year: (1) text message reminders to get tested at a local clinic (control); (2) mailed HIVST kits with access to a free helpline (standard HIVST); and (3) mailed HIVST kits with counselling provided within 24 hours of opening a kit (eTest). Quarterly follow-up surveys assessed HIV testing, sexually transmitted infection (STI) testing, pre-exposure prophylaxis (PrEP) use and sexual risk behaviour., Findings: Eight participants were diagnosed with HIV, and all but one were through HIVST. Participants in either HIVST condition, standard or eTest, had significantly higher odds of any testing (OR = 7.9, 95% CI = 4.9-12.9 and OR = 6.6, 95% CI = 4.2-10.5) and repeat testing (>1 test; OR = 8.5, 95% CI = 5.7-12.6; OR = 8.9, 95% CI = 6.1-13.4) over 12 months relative to the control group. Rates of STI testing and PrEP uptake did not differ across study condition, but those in the eTest condition reported 27% fewer sexual risk events across the study period relative to other groups., Conclusions: HIVST vastly increased testing, encouraged more regular testing among MSM, and identified nearly all new cases, suggesting that HIVST could diagnose HIV acquisition earlier. Providing timely follow-up counselling after HIVST did not increase rates of STI testing or PrEP use, but some evidence suggested that counselling may have reduced sexual risk behaviour. To encourage more optimal testing, programmes should incorporate HIVST and ship kits directly to recipients at regular intervals., (© 2024 The Author(s).

Introduction: Improving the delivery of existing evidence-based interventions to prevent and diagnose HIV is key to Ending the HIV Epidemic in the United States. Structural barriers in the access and delivery of related health services require municipal or state-level policy changes; however, suboptimal implementation can be addressed directly through interventions designed to improve the reach, effectiveness, adoption or maintenance of available interventions. Our objective was to estimate the cost-effectiveness and potential epidemiological impact of six real-world implementation interventions designed to address these barriers and increase the scale of delivery of interventions for HIV testing and pre-exposure prophylaxis (PrEP) in three US metropolitan areas., Methods: We used a dynamic HIV transmission model calibrated to replicate HIV microepidemics in Atlanta, Los Angeles (LA) and Miami. We identified six implementation interventions designed to improve HIV testing uptake ("Academic detailing for HIV testing," "CyBER/testing," "All About Me") and PrEP uptake/persistence ("Project SLIP," "PrEPmate," "PrEP patient navigation"). Our comparator scenario reflected a scale-up of interventions with no additional efforts to mitigate implementation and structural barriers. We accounted for potential heterogeneity in population-level effectiveness across jurisdictions. We sustained implementation interventions over a 10-year period and evaluated HIV acquisitions averted, costs, quality-adjusted life years and incremental cost-effectiveness ratios over a 20-year time horizon (2023-2042)., Results: Across jurisdictions, implementation interventions to improve the scale of HIV testing were most cost-effective in Atlanta and LA (CyBER/testing cost-saving and All About Me cost-effective), while interventions for PrEP were most cost-effective in Miami (two of three were cost-saving). We estimated that the most impactful HIV testing intervention, CyBER/testing, was projected to avert 111 (95% credible interval: 110-111), 230 (228-233) and 101 (101-103) acquisitions over 20 years in Atlanta, LA and Miami, respectively. The most impactful implementation intervention to improve PrEP engagement, PrEPmate, averted an estimated 936 (929-943), 860 (853-867) and 2152 (2127-2178) acquisitions over 20 years, in Atlanta, LA and Miami, respectively., Conclusions: Our results highlight the potential impact of interventions to enhance the implementation of existing evidence-based interventions for the prevention and diagnosis of HIV., (© 2024 The Author(s).

Pasteurella bettyae is a gram-negative bacillus sporadically involved in human infections; its main reservoirs are cats and dogs. A recent publication suggests the possibility of sexual transmission leading to genital infections in men who have sex with men. We report 9 cases in France of genital infection among this population.

Partner notification services (PNS) offers opportunities to discuss HIV pre-exposure prophylaxis (PrEP) and provide referrals. We evaluated the PrEP care cascade among men who have sex with men (MSM) engaging in PNS within a sexually transmitted infections clinic. Among 121 MSM eligible for PrEP during PNS, 21% subsequently initiated PrEP.

Background: Lymphogranuloma venereum (LGV) remains endemic in the United Kingdom, primarily among gay, bisexual or other men who have sex with men (GBMSM). Current treatment guidelines recommend 21 days of doxycycline, but recent evidence suggests shorter antibiotic duration is as effective. We evaluated clinical outcomes in a cohort with LGV treated with 7 days of doxycycline., Methods: We reviewed case notes of all LGV cases at a South London sexual health service between November 2016 and September 2022, treated with only 7 days of doxycycline and anonymized data were collected from electronic patient records., Results: Fifty-two individuals with detected LGV-specific DNA were treated with 7 days of doxycycline 100 mg twice daily. All were GBMSM, median age of 35 years (range, 21-64 years), 21 (40%) were living with HIV, and 18 (35%) had concomitant sexually transmitted infections. Thirty-four (65%) were asymptomatic, whereas 18 (35%) reported symptoms: 7 (13%) urethral, 11 (21%) anorectal, and 2 (4%) other symptoms. Twenty-two (42%) were prescribed additional antimicrobials; however, none were active against Chlamydia trachomatis . All 52 underwent follow-up testing (range, 4-481 days). Chlamydia trachomatis was detected in one individual, but negative for LGV-specific DNA, and so considered to be a reinfection. All other cases were C. trachomatis -negative, indicating successful LGV eradication., Conclusions: Our data support the approach of offering a 7-day doxycycline course routinely for asymptomatic or clinically mild C. trachomatis infections, and contacts of LGV infection, regardless of their LGV status. This may simplify patient management, reduce cost, and improve antimicrobial stewardship., Competing Interests: Conflicts of Interest and Sources of Funding: None declared., (Copyright © 2024 American Sexually Transmitted Diseases Association.

Background: Monkeypox virus (MPXV) is spreading globally and nearly half of the infected people were human immunodeficiency virus (HIV) positive. Therefore, an in-depth understanding of the effects of HIV infection on the outcomes of MPXV infection is urgently needed. This study aimed to explore the clinical features, viral dynamics, and antibody response to MPXV infections in men who had sex with men (MSM) with and without HIV co-infection., Design or Methods: MPXV-infected patients diagnosed by PCR were recruited in this study and were divided into MPXV and MPXV + HIV groups based on whether they were co-infected with HIV. Clinical data and samples were collected during of the hospital stay and follow up interviews. The symptoms and signs, laboratory examinations, viral shedding in various body fluids or swabs, antibody dynamics were tracked and compared between the two groups., Results: A total of 41 MPXV patients were recruited through June 2023 to September 2023 in Guangzhou. The MPXV group and MPXV + HIV group comprised 20 and 21 MSM, respectively. Patients in the two groups exhibited similar clinical characteristics except for pruritus and eschar, both were significantly fewer in MPXV + HIV group than in MPXV only group. Among the 355 clinical samples collected, MPXV DNA was detected in 100% of scabs, 97.4% of skin swabs, and 92.3% of exudate swabs from lesions, while the positive rate was 87.5% from oropharyngeal swabs, 59% from saliva, 51.3% from anal swabs, 50% from feces, 30.6% from urine samples, 37.5% of semen, and 28.2% from sera. Dynamics analysis revealed that viral DNA was undetectable in most patients 20 days after symptom onset. IgM and IgG antibodies to MPXV were detected in all patients with 3-5 days earlier in the MPXV group than in the MPXV + HIV group., Conclusion: This cohort analysis based on a large outbreak among MSM in Guangzhou indicated no obvious differences in clinical symptoms, viral DNA data, but antibody responses were 3-5 days later in mpox patients with HIV infection., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Yang, Xie, Zeng, Cao, Fan, Jiang, Lei, Wang, Li, Tang, Yu and Li.)

Introduction: In 2016, WHO estimated there were roughly 374 million new infections among adults of the following four curable sexually transmitted infections (STIs): chlamydia (caused by Chlamydia trachomatis (CT)), gonorrhoea ( Neisseria gonorrhoeae (NG)), syphilis ( Treponema pallidum ) and trichomoniasis ( Trichomonas vaginalis (TV)). Accurate point-of-care tests (POCTs) for screening of genital and extragenital CT, NG and TV infections are of great value and have been developed during recent decade. Several tests are commercially available and have shown encouraging performance compared with 'gold-standard' reference tests in laboratory-based studies. However, there is limited data on their clinical performance, including at the POC. Key populations, such as men who have sex with men (MSM), are at higher risk of these STIs at genital and extragenital sites and these STIs are often asymptomatic, especially in extragenital sites and in women. We will conduct a clinical-based evaluation to assess the performance characteristics and acceptability to end-users of molecular-based diagnostic technology for POC/near patient use of the Xpert CT/NG (Cepheid, Sunnyvale, California, USA) test for screening of genital, anorectal and pharyngeal CT and NG infections in MSM and the Xpert CT/NG and Xpert TV (Cepheid, Sunnyvale, California, USA) for screening of genital CT, NG and TV among women at risk for these STIs compared with gold-standard reference nucleic acid amplification tests. This master protocol outlines the overall research approach that will be used in seven countries., Method and Analyses: Consecutive MSM and women at risk presenting at the clinical sites in high, and low- and middle-income countries will be enrolled. The POCTs to be evaluated are Xpert CT/NG and Xpert TV. All procedures will be carried out by trained healthcare staff and tests performed in strict accordance with the manufacturer's instructions. The sensitivity, specificity, positive and negative predictive values for each POCT will be calculated. The study is ongoing with recruitment expected to be completed in all countries by mid-2022 to late-2022., Ethics and Dissemination: Prior to enrolment, this core protocol was independently peer-reviewed and approved by the research project review panel (RP2) of the WHO Department of Sexual and Reproductive Health and Research and by the WHO Ethics Review Committee (ERC). The core protocol has been slightly adapted accordingly to individual countries and adaptations approved by both RP2 and ERC, as well as all relevant institutional review boards at each participating site. Results will be disseminated through peer-reviewed journals and presented at relevant national/international conferences., Competing Interests: Competing interests: The POCT manufacturer discloses and furnishes free of charge to WHO the information and sufficient quantities of the product(s) in order to enable this evaluation as part of the WHO/RHR STI POC initiative. WHO is entitled to evaluate and publish the trial results, and to exclusively control this evaluation and the content of the aforesaid publication. WHO shall submit any proposed publication to the POCT manufacturer for review, comments received will be considered in good faith, but the decision to publish rests with WHO., (© World Health Organization 2024.

Effeminate gay bottoms, or gender nonconforming men who are anally receptive and/or give oral sex to other men who are also "gender nonconforming," are persistently marginalized in gay and LGBTQ+ communities in Britain and the US. For some LGBTQ+ commentators, "twink" has become relexified to mean a young-looking, slim, hairless effeminate bottom, whereas originally the term primarily denoted a body type and age bracket among gay men. This article explores how the twink has come to bear connotations of effeminacy and bottom subjectivity, highlighting the steady erosion of other available cultural terms to denote a bottom whose gender expression does not conform to dominant cultural masculine stereotypes. It offers an analysis of two key historical effeminate bottom identities in Britain and the US, the "fairy" and "queen," and argues that the twink not only now carries connotations originally attached to these historical identities, but that it merges their gendered and sexual connotations with new characteristics concerning age and body type that may cause considerable anxiety among contemporary gay men due to their unsustainable "shelf life."

Background: HIV-infected persons demonstrate notable disturbances in their intestinal microbiota; however, the impact of intestinal microbiota on HIV susceptibility in men who have sex with men (MSM), as well as the effects of HIV and antiretroviral therapy (ART) on their gut microbiota, remains under active study. Thus, our research focuses on clarifying the distinctions in intestinal microbiota composition among uninfected MSM and non-MSM healthy controls, investigating the alterations in early-stage intestinal microbial communities following HIV infection, and assessing how ART affects the intestinal microbiota., Methods: This study enrolled four participant groups: uninfected MSM, Recent HIV-1 infection (RHI) MSM, MSM on ART, and non-MSM healthy controls, with 30 individuals in each group. We utilized 16S ribosomal DNA (16S rDNA) amplicon sequencing to analyze fecal microbiota and employed Luminex multiplex assays to measure plasma markers for microbial translocation (LBP, sCD14) and the inflammatory marker CRP., Findings: Comparing uninfected MSM to non-MSM healthy controls, no substantial variances were observed in α and β diversity. Uninfected MSM had higher average relative abundances of Bacteroidetes, Prevotella, and Alloprevotella, while Bacteroides, Firmicutes, and Faecalibacterium had lower average relative abundances. MSM on ART had lower intestinal microbiota diversity than RHI MSM and uninfected MSM. In MSM on ART, Megasphaera and Fusobacterium increased, while Faecalibacterium and Roseburia decreased at genus level. Additionally, treatment with a non-nucleoside reverse transcriptase inhibitor (NNRTI) led to significant alterations in intestinal microbiota diversity and composition compared to RHI MSM. The random forest model showed that HIV infection biomarkers effectively distinguished between newly diagnosed HIV-infected MSM and HIV-negative MSM, with an ROC AUC of 76.24% (95% CI: 61.17-91.31%)., Conclusions: MSM showed early intestinal microbiota imbalances after new HIV infection. MSM on ART experienced worsened dysbiosis, indicating a combined effect of HIV and ART. NNRTI-based treatment notably changed intestinal microbiota, suggesting a potential direct impact of NNRTI drugs on intestinal microbiota., (© 2024. The Author(s).)

Background: Observational studies suggest that voluntary medical male circumcision (VMMC) may lower HIV risk among men who have sex with men (MSM). A randomized controlled trial (RCT) is needed to confirm this., Objective: To assess the efficacy of VMMC in preventing incident HIV infection among MSM., Design: An RCT with up to 12 months of follow-up. (Chinese Clinical Trial Registry: ChiCTR2000039436)., Setting: 8 cities in China., Participants: Uncircumcised, HIV-seronegative men aged 18 to 49 years who self-reported predominantly practicing insertive anal intercourse and had 2 or more male sex partners in the past 6 months., Intervention: VMMC., Measurements: Rapid testing for HIV was done at baseline and at 3, 6, 9, and 12 months. Behavioral questionnaires and other tests for sexually transmitted infections were done at baseline, 6 months, and 12 months. The primary outcome was HIV seroconversion using an intention-to-treat analysis., Results: The study enrolled 124 men in the intervention group and 123 in the control group, who contributed 120.7 and 123.1 person-years of observation, respectively. There were 0 seroconversions in the intervention group (0 infections [95% CI, 0.0 to 3.1 infections] per 100 person-years) and 5 seroconversions in the control group (4.1 infections [CI, 1.3 to 9.5 infections] per 100 person-years). The HIV hazard ratio was 0.09 (CI, 0.00 to 0.81; P  = 0.029), and the HIV incidence was lower in the intervention group (log-rank P  = 0.025). The incidence rates of syphilis, herpes simplex virus type 2, and penile human papillomavirus were not statistically significantly different between the 2 groups. There was no evidence of HIV risk compensation., Limitation: Few HIV seroconversions and limited follow-up period., Conclusion: Among MSM who predominantly practice insertive anal intercourse, VMMC is efficacious in preventing incident HIV infection; MSM should be included in VMMC guidelines., Primary Funding Source: The National Science and Technology Major Project of China., Competing Interests: Disclosures: Disclosures can be viewed at www.acponline.org/authors/icmje/ConflictOfInterestForms.do?msNum=M23-3317.

Objective: To evaluate the effect of preexposure prophylaxis (PrEP) initiation on bacterial sexually transmitted infection (STI) occurrence (overall; chlamydia; gonorrhea; syphilis), in MSM., Design: Systematic review and meta-analysis., Methods: Systematic searches were performed in PubMed, Embase, and Scopus without language restrictions until 1 February 2023. We sought studies reporting data for the estimation of incidence rate ratios (IRR), prevalence ratios or cumulative incidence ratios (the latter in equal time periods before and after PrEP initiation) regarding bacterial STI occurrence. Separate analyses were performed overall for any STI, syphilis, chlamydia and gonorrhea (overall; rectal; urethral; pharyngeal for the two latter conditions); ratios greater than unity denoted increase in STI occurrence after PrEP initiation., Results: Twenty-three eligible studies with 11 776 participants (age range: 18-71 years) with a median follow-up of 12 months were included. Overall, PrEP initiation was associated with a significant increase in the occurrence of any STI (pooled effect size: 1.15, 95% confidence interval (CI): 1.04-1.26), any gonorrhea (pooled effect size: 1.17, 95% CI: 1.02-1.34), any chlamydia (pooled effect size: 1.31, 95% CI: 1.09-1.58) and rectal chlamydia (pooled effect size: 1.31, 95% CI: 1.05-1.64), whereas a borderline increase was found in urethral chlamydia (pooled effect size: 1.25, 95% CI: 0.99-1.60, P  = 0.064). Changes in pharyngeal chlamydia and site-specific gonorrhea occurrence did not reach statistical significance. Syphilis showed virtually no change after PrEP initiation (pooled effect size: 0.99, 95% CI: 0.72-1.37)., Conclusion: These results highlight the need for more comprehensive, accessible STI testing to tackle bacterial STI infections in PrEP users., (Copyright © 2024 Wolters Kluwer Health, Inc.

Background: Rectal Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) infections among men who have sex with men (MSM) are escalating public health concerns. This study aimed to explore (1) the reliability of self-reported sexual positioning as an indicator for rectal CT and NG screening, and (2) factors associated with rectal CT and NG infections in Shenzhen, China., Methods: A cross-sectional study was conducted in 2 settings in Shenzhen, China, from April 1, 2021, to March 31, 2022. Data on sociodemographic characteristics, sexual behaviors, and basic CT knowledge were collected. Urine and self-collected rectal swabs were collected for CT and NG testing., Results: In total, 195 MSM participated in the study, and 5.1% tested positive for urogenital CT, 29.2% for rectal CT, 1.0% for urogenital NG, and 8.2% for rectal NG. Among those who reported exclusively insertive anal sex, 69.2% of CT infections and 85.7% of NG infections would have remained undetected with urine testing alone. Risk factors for rectal CT infection included engaging in both insertive and receptive anal sex, with a significant association found for coinfection with rectal NG., Conclusions: Self-reported sexual positioning was found to be an unreliable indicator for CT and NG screening, as a substantial proportion of infections would have remained undetected. The findings suggest that CT and NG screening in China should be offered to all MSM regardless of self-reported sexual positioning, and that the dual CT/NG testing is recommended., Competing Interests: Conflict of Interest and Sources of Funding: The authors declare no conflict of interest.

Background: Sexual behavior may influence the composition of the male urethral microbiota, but this hypothesis has not been tested in longitudinal studies of men who have sex with men (MSM)., Methods: From December 2014 to July 2018, we enrolled MSM with nongonococcal urethritis (NGU) attending a sexual health clinic. Men attended 5 in-clinic visits at 3-week intervals, collected weekly urine specimens at home, and reported daily antibiotics and sexual activity on weekly diaries. We applied broad-range 16S rRNA gene sequencing to urine. We used generalized estimating equations to estimate the association between urethral sexual exposures in the prior 7 days (insertive oral sex [IOS] only, condomless insertive anal intercourse [CIAI] only, IOS with CIAI [IOS + CIAI], or none) and Shannon index, number of species (observed, oral indicator, and rectal indicator), and specific taxa, adjusting for recent antibiotics, age, race/ethnicity, HIV, and preexposure prophylaxis., Results: Ninety-six of 108 MSM with NGU attended ≥1 follow-up visit. They contributed 1140 person-weeks of behavioral data and 1006 urine specimens. Compared with those with no urethral sexual exposures, those with IOS only had higher Shannon index ( P = 0.03 ) but similar number of species and presence of specific taxa considered, adjusting for confounders; the exception was an association with Haemophilus parainfluenzae . CIAI only was not associated with measured aspects of the urethral microbiota. IOS + CIAI was only associated with presence of H. parainfluenzae and Haemophilus ., Conclusions: Among MSM after NGU, IOS and CIAI did not seem to have a substantial influence on measured aspects of the composition of the urethral microbiota., Competing Interests: Conflict of Interest of Sources of Funding: This work was supported by the National Institutes of Health (grant number U19 AI113173).

Background: Standard-of-care nucleic acid amplification tests (routine NAATs) for Neisseria gonorrhoeae (GC) and Chlamydia trachomatis (CT) can take several days to result and therefore delay treatment. Rapid point-of-care GC/CT NAAT (rapid NAAT) could reduce the time to treatment and therefore onward transmission. This study evaluated the incremental cost per infectious day averted and overall cost of implementation associated with rapid compared with routine NAAT., Methods: Prospective sexually transmitted infection (STI) treatment data from men who have sex with men and transgender women in San Diego who received rapid NAAT between November 2018 and February 2021 were evaluated. Historical time from testing to treatment for routine NAAT was abstracted from the literature. Costs per test for rapid and routine NAAT were calculated using a micro-costing approach. The incremental cost per infectious day averted comparing rapid to routine NAAT and the costs of rapid GC/CT NAAT implementation in San Diego Public Health STI clinics were calculated., Results: Overall, 2333 individuals underwent rapid NAAT with a median time from sample collection to treatment of 2 days compared with 7 to 14 days for routine NAAT equating to a reduction of 5 to 12 days. The cost of rapid and routine GC/CT NAAT was $57.86 and $18.38 per test, respectively, with a cost-effectiveness of between $2.43 and $5.82 per infectious day averted. The incremental cost of rapid NAAT improved when at least 2000 tests were performed annually., Conclusions: Although rapid GC/CT NAAT is more expensive than routine testing, the reduction of infectious days between testing and treatment may reduce transmission and provide improved STI treatment services to patients., Competing Interests: Conflict of Interest and Sources of Funding: S.J.L. has received funding from Gilead Sciences paid to her institution and donation of medications from Gilead Sciences.

Objectives: We aimed to assess whether a self-collected oral rinse was non-inferior to clinician-collected oropharyngeal swabs to detect Neisseria gonorrhoeae (Ng) using culture and nucleic acid amplification tests (NAAT) among men who have sex with men (MSM), and whether Ng may still be detected in oral rinses for a minimum of 5 days after collection., Methods: MSM with a positive Ng result in an oropharyngeal or pooled sample (oropharynx, urethra and anorectum) were approached. Clinician-collected oropharyngeal swabs and oral rinses (15 mL sterile water) were taken. Ng culture and NAAT (Abbott 2000m RealTime System CT/NG assay and in-house PCR) were performed. Diagnostic accuracy was assessed using sensitivity and specificity, and agreement between both techniques using Cohen's kappa statistic. Aliquots of positive oral rinses were left at room temperature for a minimum of 5 days and reanalysed using NAAT. Lastly, participants filled in a questionnaire to explore perceptions of both methods., Results: We included 100 participants between June 2022 and October 2023. 45 individuals (45 of 100) had a positive Ng result in either the oral rinses (42 of 45, 93%) or the swabs (36 of 45, 80%). Sensitivity was higher for oral rinses than swabs (sensitivity=0.93/0.80, specificity=1.0/1.0, respectively) and agreement between both techniques was good (kappa=0.75, p<0.001). Of the 42 positive oral rinses, 37 remained positive after a minimum of 5 days (88.1%). Using culture, 18 individuals had a positive Ng result in either the oral rinses (8 of 18, 44%) or the swabs (16 of 18, 88%). Most participants found the oral rinse easy or very easy to use and would be willing to use the oral rinse for home-based sampling., Conclusion: We detected more oropharyngeal Ng infections via NAAT using oral rinses than swab samples. However, swabs were better than oral rinses for culturing Ng. Oral rinses might allow for home-based self-sampling to detect oropharyngeal Ng., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Kaposi sarcoma (KS) continues to cause substantial morbidity and mortality in populations at risk in the southern United States. Utilizing biospecimens from the Houston site of the Young Men's Affiliate Project, 351 men who have sex with men had blood tested for KS-associated herpesvirus (KSHV) IgG. Seroprevalence, seroconversion between time points, and demographic and clinical correlates were measured. KSHV prevalence was 36.7% and incidence was 8.9 per 100 person-years. Furthermore, prevalence and incidence were higher among Black individuals, people living with HIV, and those with a history of syphilis. Further research on KSHV risk may improve health disparities in KS diagnosis and outcomes., Competing Interests: Potential conflicts of interest. A. E.

This article explores how gay men in Iceland were constructed as good responsible citizens through neoliberal discourses from 1990 to 2010. Drawing on interviews with gay men in Icelandic magazines, we focus on three discursive formations of responsibilization that reveal the technologies of agency at play in transforming the men into good, responsible gay citizens capable of self-management. The discursive formations focus on the good gay citizen who (a) has a positive mind-set, (b) transforms himself, and (c) displaces responsibility for personal harm. They reveal how gay men are constituted as neoliberal subjects through discursive practices linked to responsibility, happiness, and national progress. These practices enable a normalization process devoid of confrontation, anger, or blame where gay men are not only made responsible for their own lives but also the marginalization they experienced in the past.

Chemsex refers to the use of psychoactive substances with sex. We carried out a systematic scoping review of methodological characteristics of chemsex research among men who have sex with men (MSM), published between 2010 and 2020. For inclusion, chemsex had to be the main focus, and studies had to specify GHB/GBL, stimulant (amphetamine, crystal meth, ecstasy/MDMA, cathinones, cocaine) and/or ketamine use with sex as a variable. From 7055 titles/abstracts, 108 studies were included, mostly cross-sectional, and from Western countries. About one-third of studies recruited exclusively from clinical settings. A majority of these recruited from sexually transmitted infection (STI) clinics. The included quantitative studies analyzed possible associations between chemsex and STI health (40%), mental health (15%), drug health (12%), sexological health (10%), and post-diagnostic HIV health (7%). Most studies included GHB/GBL and crystal meth in their operationalization of chemsex. Definitions and operationalizations of chemsex vary greatly in the literature, and researchers of chemsex among MSM should consider ways in which this variation impacts the validity of their results. More studies are needed among MSM in non-high income and non-Western countries, and examination of possible links between chemsex and post-diagnostic HIV health, sexological health, and mental health.

Background: Engaging in anal sexual intercourse markedly increases the risk of developing HIV among men who have sex with men (MSM); oral sexual activities tend to uniquely introduce gut-derived microbes to salivary microbiota, which, combined with an individual's positive HIV status, may greatly perturb oral microecology. However, till date, only a few published studies have addressed this aspect., Methods: Based on 16S rRNA sequencing data of bacterial taxa, MicroPITA picks representative samples for metagenomic analysis, effectively revealing how the development and progression of the HIV disease influences oral microbiota in MSM. Therefore, we collected samples from 11 HIV-negative and 44 HIV-positive MSM subjects (stage 0 was defined by HIV RNA positivity, but negative or indeterminate antibody status; stages 1, 2, and 3 were defined by CD4 + T lymphocyte counts ≥ 500, 200-499, and ≤ 200 or opportunistic infection) and selected 25 representative saliva samples (5 cases/stage) using MicroPITA. Metagenomic sequencing analysis were performed to explore whether positive HIV status changes salivary bacterial KEGG function and metabolic pathway in MSM., Results: The core functions of oral microbiota were maintained across each of the five groups, including metabolism, genetic and environmental information processing. All HIV-positive groups displayed KEGG functions of abnormal proliferation, most prominently at stage 0, and others related to metabolism. Clustering relationship analysis tentatively identified functional relationships between groups, with bacterial function being more similar between stage 0-control groups and stage 1-2 groups, whereas the stage 3 group exhibited large functional changes. Although we identified most metabolic pathways as being common to all five groups, several unique pathways formed clusters for certain groups; the stage 0 group had several, while the stage 2 and 3 groups had few, such clusters. The abundance of K03046 was positively correlated with CD4 counts., Conclusion: As HIV progresses, salivary bacterial function and metabolic pathways in MSM progressively changes, which may be related to HIV promoting abnormal energy metabolism and exacerbate pathogen virulence. Further, infection and drug resistance of acute stage and immune cell destruction of AIDS stage were abnormally increased, predicting an increased risk for MSM individuals to develop systemic and oral diseases., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Guo, Wang, Yu, Sun, Zhang, Wang, Cao, Wen, Wang, Li, Cai, Wu, Duan, Xia, Wei, Duan, Dong, Guo, Zhang, Sun and Huang.)

Background: An increasing number of countries are currently implementing or scaling-up HIV pre-exposure prophylaxis (PrEP) care. With the introduction of PrEP, there was apprehension that condom use would decline and sexually transmitted infections (STIs) would increase. To inform sexual health counselling and STI screening programmes, we aimed to study sexual behaviour and STI incidence among men who have sex with men (MSM) and transgender women who use long-term daily or event-driven PrEP., Methods and Findings: The Amsterdam PrEP demonstration project (AMPrEP) was a prospective, closed cohort study, providing oral daily PrEP and event-driven PrEP to MSM and transgender women from 2015 to 2020. Participants could choose their PrEP regimen and could switch at each three-monthly visit. STI testing occurred at and, upon request, in-between 3-monthly study visits. We assessed changes in numbers of sex partners and condomless anal sex (CAS) acts with casual partners over time using negative binomial regression, adjusted for age. We assessed HIV incidence and changes in incidence rates (IRs) of any STI (i.e., chlamydia, gonorrhoea, or infectious syphilis) and individual STIs over time using Poisson regression, adjusted for age and testing frequency. A total of 367 participants (365 MSM) commenced PrEP and were followed for a median 3.9 years (interquartile range [IQR] = 3.4-4.0). Median age was 40 years (IQR = 32-48), 315 participants (85.8%) self-declared ethnicity as white and 280 (76.3%) had a university or university of applied sciences degree. Overall median number of sex partners (past 3 months) was 13 (IQR = 6-26) and decreased per additional year on PrEP (adjusted rate ratio [aRR] = 0.86/year, 95% confidence interval [CI] = 0.83-0.88). Overall median number of CAS acts with casual partners (past 3 months) was 10 (IQR = 3-20.5) and also decreased (aRR = 0.92/year, 95% CI = 0.88-0.97). We diagnosed any STI in 1,092 consultations during 1,258 person years, resulting in an IR of 87/100 person years (95% CI = 82-92). IRs of any STI did not increase over time for daily PrEP or event-driven PrEP users. Two daily PrEP users, and no event-driven PrEP users, were diagnosed with HIV during their first year on PrEP. Study limitations include censoring follow-up due to COVID-19 measures and an underrepresentation of younger, non-white, practically educated, and transgender individuals., Conclusions: In this prospective cohort with a comparatively long follow-up period of 4 years, we observed very low HIV incidence and decreases in the numbers of casual sex partners and CAS acts over time. Although the STI incidence was high, it did not increase over time., Trial Registration: The study was registered at the Netherlands Trial Register (NL5413) https://www.onderzoekmetmensen.nl/en/trial/22706., Competing Interests: PA has received personal fees from Gilead, Merck, Viiv, and research support from Gilead, paid to his institution.

From June 16 to 30, 2023, men who have sex with men (MSM) who had visited Voluntary Counseling Testing (VCT) clinics in the Luohu, Futian and Nanshan districts of Shenzhen were included in this study to analyze their awareness of Mpox and the influencing factors. The mean age of the 262 MSM was (34.78±8.94) years, with the majority being unmarried (75.2%) and 79.0% confirmed to be infected with HIV. The awareness rates for five primary indicators, current status of Mpox, pathogen and source of infection, mode of transmission, population susceptibility, clinical manifestations and treatment were 68.4%, 84.7%, 60.3%, 87.8%, and 52.5%, respectively. The awareness rates for five secondary indicators, earliest transmission location (44.7%), main mode of transmission (54.2%), role of masks (46.9%), drug accessibility (46.6%), and self-limiting nature (38.2%) were all below 60%. The MSM population in Shenzhen perceived their likelihood of being infected (2.76±1.32) and discriminated against (3.87±1.26) as relatively low. The logistic analysis showed that the high school or vocational school education ( OR :3.094, 95 %CI: 1.180-9.299), college or above education ( OR :5.360, 95% CI :2.159-15.501), and higher scores on questions affecting learning or work ( OR :2.196, 95% CI :1.409-3.599) were promoting factors for Mpox awareness, while higher scores on questions concerning the possibility of Mpox mortality ( OR :0.591, 95% CI :0.432-0.791) was the hindering factor for Mpox awareness.

The unique recombinant form (URF) of HIV is formed by multiple subtypes which are cocirculating in some area, and the number of HIV recombinants is on the increase worldwide. In this study, we identified a URF named 2019638, composed of CRF01&#95;AE and subtype B, in a man who has sex with men in Qinhuangdao, Hebei province, China. The near-full-length genome (NFLG) sequence was confirmed to be a novel URF. Within this NFLG, two CRF01&#95;AE fragments were inserted into the pol and vif regions, respectively, using subtype B as the backbone. Moreover, the presence of the V106M and V179D point mutations in the reverse transcriptase (RT) region rendered the high-level resistance to efavirenz and nevirapine and intermediate resistance to doravirine. Our findings suggest that the HIV epidemic is evolving toward a high degree of recombination, and we need to continuously monitor HIV genetic diversity to control the further development of the AIDS epidemic.

The 2022 mpox (formerly monkeypox) outbreak affected predominantly men who have sex with men (MSM), likely through sexual transmission, which resulted in institutions specializing in sexual health being at the frontlines of the mpox outbreak. Fenway Health in Boston serves close to 10 000 MSM annually, which includes more than 2400 MSM who are living with HIV and 3320 MSM with active HIV preexposure prophylaxis (PrEP) prescriptions. We report on the programs implemented and changes to clinical practice at Fenway Health during the mpox outbreak. Fenway Health diagnosed its first case of mpox in June 2022 and treated this patient with tecovirimat. In early July 2022, Fenway Health administered its first dose of the Jynneos vaccine under the Emergency Use Authorization for protection against mpox. As of October 6, 2022, 69 people had tested positive for the mpox virus at Fenway Health. Among the 69 people who tested positive, 43 (62.3%) self-identified as male, with the remaining not reporting a sex or gender identity, and 40 (58.0%) reported their sexual orientation as gay or bisexual. Twenty-five people (36.2%) were treated with tecovirimat. As of October 30, 2022, Fenway Health had administered 6376 doses of the Jynneos vaccine. The programmatic changes involved in rollout and scale-up of vaccination, treatment, and community outreach services at Fenway Health during the 2022 mpox outbreak that we describe here could inform strategies to address subsequent outbreaks., Competing Interests: Declaration of Conflicting InterestsThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.
