To discuss the risks that heteronormative assumptions play in prostate cancer care and how these may be addressed.There is international evidence to support the case that LGBT patients with cancer are less likely to report poor health or self-disclose sexual orientation. Gender-specific cancers, such as prostate cancer, require particular interventions in terms of supportive care. These may include advice about side-effect management (such as incontinence or erectile dysfunction), treatment choices and social and emotional issues. In this paper, we discuss and analyse the heteronormative assumptions and culture that exist around this cancer. We argue that this situation may act as a barrier to effective supportive care for all Lesbian women, Gay, Transgender and Bisexual patients, in this case men who have sex with men. [Correction added on 21 September 2017, after first online publication: The first sentence of the Background section has been revised for clarity in this current version.] DESIGN: Theoretical exploration of heteronormativity considered against the clinical context of prostate cancer.Identification and inclusion of relevant international evidence combined with clinical discussion.This paper posits a number of questions around heteronormativity in relation to prostate cancer information provision, supportive care and male sexuality. While assumptions regarding sexual orientation should be avoided in clinical encounters, this may be difficult when heteronormative assumptions dominate. Existing research supports the assertion that patient experience, including the needs of LGBT patients, should be central to service developments.Assumptions about sexual orientation should be avoided and recorded accurately and sensitively, and relational models of care should be promoted at the start of cancer treatment in an appropriate manner. These may assist in reducing the risks of embarrassment or offence to nonheterosexual patients, or to professionals who may adopt heteronormative assumptions.Having an awareness of the risks of making heteronormative assumptions in clinical practice will be useful for all health professionals engaged in prostate cancer care. This awareness can prevent embarrassment or upset for patients and ensure a more equitable provision of service, including men with prostate cancer who do not identify as heterosexual.

IntroductionMen who have sex with men (MSM) are one of the most at-risk group for contracting HIV in the USA. However, the HIV epidemic impacts some groups of MSM disproportionately. Latino MSM comprise 25.1% of new HIV infections among MSM between the ages of 13 and 29 years. The daily medication tenofovir/emtricitabine was approved by the Food and Drug Administration for pre-exposure prophylaxis (PrEP) in 2012 and has demonstrated strong efficacy in reducing HIV acquisition.Methods and analysisThrough extensive formative research, this study uses a pilot randomised controlled trial design and will examine the feasibility and acceptability of a patient navigation intervention designed to address multiple barriers to improve engagement in the PrEP continuum among 60 Latino MSM between the ages of 18 and 29 years. The patient navigation intervention will be compared with usual care plus written information to evaluate the feasibility and acceptability of the intervention and study methods and the intervention’s potential in improving PrEP continuum behaviours. The results will be reviewed for preparation for a future full-scale efficacy trial.Ethics and disseminationThis study was approved by the institutional review board at San Diego State University and is registered at ClinicalTrials.gov. The intervention development process, plan and the results of this study will be shared through peer-reviewed journal publications, conference presentations and healthcare system and community presentations.Registration detailsRegistered under the National Institutes of Health’s ClinicalTrials.gov (NCT04048382) on 7 August 2019 and approved by the San Diego State University (HS-2017–0187) institutional review board. This study began on 5 August 2019 and is estimated to continue through 31 March 2021. The clinical trial is in the pre-results stage.

Alcohol-using Black MSM (Men who have sex with men) are disproportionately impacted by HIV in the U.S.—particularly in the southern U.S.—despite the availability of antiretroviral therapy (ART). The purpose of this study was to summarize the current evidence on alcohol use and ART adherence among Black MSM in the U.S. and in the South and to identify future research needs. A systematic review was conducted using eight databases to identify relevant peer-reviewed articles published between January 2010 and April 2021. The authors also snowballed remaining studies and hand-searched for additional studies. Including both quantitative and qualitative studies, five published studies examined alcohol and ART adherence among Black MSM in the U.S. The search identified 240 articles, the study team reviewed 114 in full-text and determined that only five met the inclusion criteria. Three of the five included studies identified alcohol use as a barrier to ART adherence. In conclusions, the general lack of literature on HIV disparities among alcohol-using Black MSM in the U.S. (specifically in the South) indicates a critical need for research on this population’s unique risks and needs to inform the development of tailored interventions.

Data on long-term survival among people with HIV (PWH) can inform the development of services for this population. An estimated 90,000 PWH live in New York City (NYC). Using HIV surveillance data, we conducted survival analysis of PWH diagnosed in NYC before and after introduction of highly active antiretroviral therapy (HAART) (pre-HAART cohort: 1981–1994; post-HAART cohort: 1995–2016). We created Kaplan–Meier curves by cohort and demographic factors, and Cox proportional hazards models to evaluate adjusted mortality risk by cohort. 205,584 adults and adolescents were diagnosed with HIV in NYC from 1981 to 2016, half each in the pre-HAART and post-HAART eras. The pre-HAART cohort had significantly poorer survival compared with the post-HAART cohort. Adjusted mortality risk in the pre-HAART cohort was almost threefold that in the post-HAART cohort (HR 2.84, 95% confidence interval [CI] 2.80–2.88). In sex- and risk-stratified models, men who have sex with men (MSM) had the largest difference in mortality risk pre-HAART versus post-HAART (HR 5.41, 95% CI 5.23–5.59). Race/ethnic disparities were pronounced among MSM, with Latino/Hispanic and White MSM having lower mortality than Black MSM. Females with heterosexual risk born outside the US had lower mortality than US-born women. The improvement in survival post-HAART was most pronounced for White people. Survival among persons diagnosed with HIV in NYC increased significantly since the introduction of HAART. However, among MSM and among PWH overall, improvements even post-HAART lagged for Black and Latino/Hispanic people, underscoring the need to address structural barriers, including racism, to achieve optimal health outcomes among people with HIV.

The COVID-19 pandemic has caused disruptions to health care access for sexual and gender minorities in the U.S. We sought to explore the impact of COVID-19 on HIV pre-exposure prophylaxis (PrEP) use and sexual health services by assessing PrEP eligibility and use, changes in sexual behaviors, and HIV/STI testing during the COVID-19 pandemic. We surveyed 239 young sexual minority men (YSMM) 17-24 years old between April and September 2020 in the U.S. One-in-seven YSMM PrEP users discontinued use during the pandemic, and all those who discontinued PrEP reported a decrease in sexual activity. Twenty percent reported difficulty getting prescriptions and medications from their doctors or pharmacies, and more than 10% reported challenges accessing HIV/STI testing. Among those who met Centers for Disease Control and Prevention criteria for PrEP (n = 104), 86.5% were not currently using PrEP. Among those surveyed 3 months or later after the start of major COVID-19 stay-at-home measures (n = 165), 35.8% reported CAS with a causal partner within the past 3 months during the COVID-19 pandemic. Seeking HIV testing was associated with reporting condomless anal sex in the previous 3 months, indicating the necessity for ensuring continuity of basic sexual health services for YSMM. Failure to adequately adjust HIV prevention services and intervention in the face of pandemic-related adversity undermines efforts to end the HIV epidemic in the U.S.La pandemia de COVID-19 ha causado interrupciones en el acceso a la atención médica para las minorías sexuales y de género en los EE. UU. Buscamos explorar el impacto de COVID-19 en el uso de la profilaxis de preexposición al VIH (PrEP) y los servicios de salud sexual mediante la evaluación de la elegibilidad y el uso de PrEP, los cambios en los comportamientos sexuales y las pruebas de VIH/ITS durante la pandemia de COVID-19. Encuestamos a 239 hombres jóvenes de minorías sexuales (YSMM) de 17 a 24 años entre abril y septiembre de 2020 en los EE. UU. Uno de cada siete usuarios de PrEP YSMM interrumpió su uso durante la pandemia, y todos los que interrumpieron la PrEP informaron una disminución en la actividad sexual. El veinte por ciento informó tener dificultades para obtener recetas y medicamentos de sus médicos o farmacias, y más del 10% informó tener dificultades para acceder a las pruebas de VIH/ITS. Entre los que cumplieron con los criterios de los Centros para el Control y la Prevención de Enfermedades para la PrEP (n = 104), el 86,5% no estaba usando PrEP actualmente. Entre los encuestados 3 meses o más después del inicio de las principales medidas de COVID-19 para quedarse en casa (n = 165), el 35,8% informó CAS con una pareja causal en los últimos 3 meses durante la pandemia de COVID-19. La búsqueda de la prueba del VIH se asoció con la notificación de sexo anal sin condón en los 3 meses anteriores, lo que indica la necesidad de garantizar la continuidad de los servicios básicos de salud sexual para YSMM. No ajustar adecuadamente los servicios de prevención del VIH y la intervención frente a la adversidad relacionada con la pandemia socava los esfuerzos para poner fin a la epidemia del VIH en los EE. UU.

Tijuana, Mexico, has a concentrated HIV epidemic among overlapping key populations (KPs) including people who inject drugs (PWID), female sex workers (FSW), their male clients, and men who have sex with men (MSM). We developed a dynamic HIV transmission model among these KPs to determine the extent to which their unmet prevention and treatment needs is driving HIV transmission. Over 2020-2029 we estimated the proportion of new infections acquired in each KP, and the proportion due to their unprotected risk behaviours. We estimate that 43.7% and 55.3% of new infections are among MSM and PWID, respectively, with FSW and their clients making-up 10% of new infections. Projections suggest 93.8% of new infections over 2020-2029 will be due to unprotected sex between MSM or unsafe injecting drug use. Prioritizing interventions addressing sexual and injecting risks among MSM and PWID are critical to controlling HIV in Tijuana.Tijuana, México, tiene una epidemia de VIH concentrada en poblaciones claves (PC) superpuestas que incluyen personas que se inyectan drogas (PID), trabajadoras sexuales (MTS), sus clientes hombres, y hombres que tienen sexo con hombres (HSH). Desarrollamos un modelo dinámico de transmisión de VIH en estas PC para determinar hasta dónde sus necesidades no atendidas de prevención y tratamiento dirigen la transmisión del VIH. Para 2020–2029 estimamos la proporción de nuevas infecciones adquiridas en cada PC, y la proporción atribuida a sus comportamientos de riesgo sin protección. Estimamos que 43.7% y 55.3% de nuevas infecciones se dan en HSH y PID, respectivamente, con MTS y clientes conformando 10% de nuevas infecciones. Las proyecciones sugieren que 93.8% de nuevas infecciones en 2020–2029 se deberán a sexo sin protección en HSH o uso inseguro de drogas inyectables. Dar prioridad a intervenciones que atienden los riesgos sexual y de inyección en HSH y PID es crítico para controlar el VIH en Tijuana.

The purpose of this study was to evaluate the impact of the Coronavirus Disease 2019 (COVID-19) pandemic on sexual behavior, mental health, and substance use among men who have sex with men (MSM) engaged in pre-exposure prophylaxis (PrEP) care. Generalized linear mixed models and logistic mixed-effect models examined change over time for number of sexual partners, mood, and alcohol consumption. From February 29, 2020 to July 31, 2020, 177 MSM actively engaged in PrEP care were evaluated. The median age was 37 [interquartile range (IQR 30, 51]. Patients in the sample were largely representative of the clinic population and identified as White (73.0%), Black/African American (9.2%), and other race (17.2%), and 11.8% identified as Hispanic/Latino ethnicity. Men reported an average of 2.60 fewer sexual partners (95% CI -4.04, -1.40) during the pandemic compared to pre-COVID-19. Rates of depressive symptoms and alcohol use remained stable and few patients reported substance use. The reduced number of sexual partners may be explained by patients' efforts to reduce risk of exposure to COVID-19 and low rates of psychosocial symptoms may be indicative of only the highest functioning patients continuing to engage in care. Reductions in sexual partners may offset reduced engagement in care and help mitigate risk of HIV and other sexually transmitted infections (STIs).El propósito de este estudio fue evaluar el impacto que tuvo la pandemia causada por la enfermedad del coronavirus 2019 (COVID-19) en el comportamiento sexual, la salud mental y el uso de sustancias en hombres que tienen sexo con hombres (HSH) que reciben profilaxis previa a la exposición (PrEP). Los modelos lineales mixtos generalizados y los modelos logísticos de efectos mixtos examinaron el cambio a través del tiempo en el número de parejas sexuales, el estado de ánimo y el consumo de alcohol. Desde el 29 de febrero de 2020 hasta el 31 de julio de 2020, se evaluaron 177 HSH que recibían los servicios de la PrEP. La mediana de edad fue de 37 (rango intercuartílico (IQR: 30, 51). Los pacientes de la muestra eran en gran parte representativos de la población de la clínica y se identificaban como Blancos (73.0%), Negros/Afroamericanos (9.2%) y de Otra raza (17.2%) y el 11.8% se identificó de origen Hispano/Latino. Los hombres reportaron un promedio de 2.60 parejas sexuales menos (IC del 95%: -4.04, -1.40) durante la pandemia en comparación con antes de COVID-19. Las tasas de síntomas depresivos y el uso de alcohol se mantuvieron estables y pocos pacientes reportaron uso de sustancias. El número reducido de parejas sexuales puede explicarse por los esfuerzos de los pacientes para reducir su riesgo de exposición al COVID-19 y las bajas tasas de síntomas psicosociales pueden ser indicativos de que solo los pacientes con mayor funcionamiento continúan participando. La reducción en el número de parejas sexuales puede contrarrestar la baja participación en la atención medica de la PrEP y ayudar a mitigar el riesgo de contraer el VIH y otras infecciones de transmisión sexual (ITS).

Indonesia’s HIV epidemic is concentrated among key populations. While prevalence among men who have sex with men (MSM) is high, transmission among young MSM (15–24-years-old) remains poorly understood. We conducted a respondent driven sampling survey of 211 young MSM in urban Bandung, Indonesia in 2018–2019 to estimate HIV prevalence and associated risk factors. Thirty percent of young MSM were HIV antibody positive. This is nearly 100-fold greater than Indonesia’s population prevalence and sevenfold higher than average estimates for young MSM across Asia and the Pacific Region. Individual risk factors associated with HIV infection were being 20–24 years old, having a steady partner and preferring the receptive position during sex. Issues of stigma, discrimination and social exclusion were common. Few young MSM who were open with friends and family members about their sexual identity. Among those that were, close to half reported experiencing feelings of aversion from these groups. Wider structural factors that reduce social tolerance, restrict the rights of young MSM and compel concealment of sexual identity are likely to fuel high-risk behaviors and limit access to essential testing care and support services including pre-exposure prophylaxis which is not yet widely available. Urgent health, social, legal and political actions are required to respond to these factors and reduce the disproportionate contribution of young MSM to Indonesia’s HIV epidemic.

HIV risk perception plays a crucial role in the uptake of preventive strategies. We investigated how risk perception and its determinants changed between 1999 and 2018 in an open, prospective cohort of 1323 HIV-negative men who have sex with men (MSM). Risk perception, defined as the perceived likelihood of acquiring HIV in the past 6 months, changed over time: being relatively lower in 2008–2011, higher in 2012–2016, and again lower in 2017–2018. Irrespective of calendar year, condomless anal intercourse (AI) with casual partners and high numbers of partners were associated with higher risk perception. In 2017–2018, condomless receptive AI with a partner living with HIV was no longer associated with risk perception, while PrEP use and condomless AI with a steady partner were associated with lower risk perception. We showed that risk perception has fluctuated among MSM in the past 20 years. The Undetectable equals Untransmittable statement and PrEP coincided with lower perceived risk.

Sexual agreements are an important element of HIV prevention for many partnered gay, bisexual, and other men who have sex with men (GBMSM). This study describes sexual agreement and sexual behavior changes during the 2020 pandemic among a sample of 215 coupled US GBMSM. Overall, reported behavior shifted towards monogamy. Fifteen percent of respondents developed/ended/changed their agreement during the pandemic; the pandemic factored into 85% of reported changes. Individuals reported fewer outside sexual partners compared to the 3 months pre-pandemic. More research is needed to investigate shifting behavior and associated risk in order to adapt HIV services during the pandemic.

Despite the prevailing consensus on the role that stigma and discrimination play in limiting access to HIV prevention technology, discouraging HIV testing, and impeding access to HIV care, studies that focus on structural interventions to address stigma and discrimination for gay, bisexual, and other men who have sex with men and transgender women are surprisingly uncommon. We aimed to identify the outcomes from a coordinated set of community-led advocacy initiatives targeting structural changes that might eliminate barriers to HIV care for gay and bisexual men and transgender women in five African and two Caribbean countries. We conducted a prospective evaluation that included repeated site visits and in-depth semi-structured interviews with 112 people with direct knowledge of project activities, accomplishments, failures, and challenges. Using outcome harvesting and qualitative analysis methods, we observed that over the 18-month implementation period, local advocacy efforts contributed to enhanced political will on the part of duty bearers for ensuring equitable access to HIV care, increases in the availability of affirming resources, improved access to existing resources, and changes in normative institutional practices to enable access to HIV care. Evidence on Project ACT points to the vital role community-led advocacy plays in addressing stigma and discrimination as structural barriers to HIV care.Estudios cual centran en intervenciones estructurales para abordar el estigma y la discriminación de los hombres gay, bisexuales y otros hombres que tienen sexo con hombres y mujeres transgénero son sorprendentemente poco comunes, a pesar del consenso prevaleciente sobre el rol que desempeñan el estigma y la discriminación al limitar el acceso a la tecnología de prevención del VIH, desalentar las pruebas del VIH e impedir el acceso a la atención del VIH. Nuestro objetivo era identificar los resultados de un conjunto coordinado de iniciativas de incidencia política dirigidas por la comunidad que apuntan a cambios estructurales que podrían eliminar las barreras a la atención del VIH para hombres gay y bisexuales y mujeres transgénero en cinco países de África y dos del Caribe. Realizamos una evaluación prospectiva que incluyó visitas repetidas al sitio y entrevistas profundas semiestructuradas con 112 personas con conocimiento directo de las actividades, logros, fracasos y desafíos del proyecto. Utilizando métodos de recolección de resultados y análisis cualitativo, observamos que durante el período de implementación de 18 meses, los esfuerzos de promoción local contribuyeron a una mayor voluntad política por parte de los titulares de deberes para garantizar el acceso equitativo a la atención del VIH, aumentos en la disponibilidad de recursos afirmativos, mejoras al acceso a los recursos existentes y cambios en las prácticas institucionales normativas para permitir el acceso a la atención del VIH. La evidencia sobre el Proyecto ACT apunta al papel vital que desempeñan las iniciativas de incidencia política liderada por la comunidad para abordar el estigma y la discriminación como barreras estructurales para la atención del VIH.

HIV incidence among men who have sex with men (MSM) in Greece remains unchanged despite effective response to a recent outbreak among people who inject drugs (PWID). Network factors are increasingly understood to drive transmission in epidemics. The primary objective of the study was to characterize MSM in Greece, their sexual behaviors, and sexual network mixing patterns. We investigated the relationship between serostatus, sexual behaviors, and self-reported sex networks in a sample of MSM in Athens, Greece, generated using respondent driven sampling. We estimated mixing coefficients (r) based on survey-generated egonets. Additionally, multiple logistic regression was used to estimate adjusted odds ratios (AOR) and to assess relationships between serostatus, sexual behaviors, and sociodemographic indicators. A sample of 1,520 MSM participants included study respondents (n = 308) and their network members (n = 1,212). Mixing based on serostatus (r = 0.12, σr = 0.09–0.15) and condomless sex (r = 0.11, σr = 0.07–0.14) was random. However, mixing based on sex-drug use was highly assortative (r = 0.37, σr = 0.32–0.42). This study represents the first analysis of Greek MSM sexual networks. Our findings highlight protective behavior in two distinct network typologies. The first typology mixed assortatively based on serostatus and sex-drug use and was less likely to engage in condomless sex. The second typology mixed randomly based on condomless sex but was less likely to engage in sex-drug use. These findings support the potential benefit of HIV prevention program scale-up for this population including but not limited to PrEP.

HIV testing among young Black MSM and transwomen (YBMSM/TW) is the gateway to biomedical HIV prevention or treatment. HIV self-testing (HST) is a method that may increase consistent HIV testing. TRUST, a brief, peer-based behavioral intervention, was designed to increase uptake of consistent (every three months) HST among YBMSM/TW in New York City. To test the efficacy of the intervention, we randomized 200 friend pairs into either the intervention condition (TRUST) or a time and attention control condition. A modified intent-to-treat analysis found that self-reported HST at 3-month follow-up was statistically significantly higher (uOR 2.29; 95% CI 1.15, 4.58) and at 6-month follow-up was marginally statistically significantly higher (uOR 1.94; 95% CI 1.00, 3.75) in the intervention arm as compared with the control arm. There were no statistically significant differences by arm at 9- or 12-month follow-up. TRUST, a culturally-congruent intervention to increase HST among YBMSM/TW, had short-term impact on past-three month HST. Clinical Trials Registration ClinicalTrial.gov NCT04210271.

Improving HIV testing rates and increasing early detection among men who have sex with men (MSM) are critical strategies for enhancing overall health and decreasing HIV transmission. Remote testing and phone delivery of HIV test results may reduce barriers such as geographic isolation or HIV-related stigma. In 2018-19, 50 MSM completed qualitative interviews about their experience receiving a positive HIV test result via phone through their participation in a research study that included remote HIV testing. Interview topics included the acceptability of, and concerns about, phone delivery of HIV results, as well as suggestions for improvement. Interviews were transcribed, coded, and analysed using an inductive thematic approach. Overall, participants reported high acceptability of phone delivery of HIV-positive results. Participants praised the support and information provided by study staff. Benefits identified included increased convenience compared to in-person medical visits, allowing participants to emotionally process their test results privately, as well as receiving the results from supportive and responsive staff members. A few participants indicated drawbacks to phone-based HIV test result delivery, such as logistical concerns about receiving a phone call during the day (e.g., while at work), reduced confidentiality, and the lack of in-person emotional support. Overall, participants described phone delivery of positive HIV-results as acceptable. At-home testing with phone delivery has the potential to increase HIV testing access, especially to geographically isolated or medically underserved patients.

Despite increased availability of pre-exposure prophylaxis (PrEP), PrEP uptake has remained low. To promote uptake, factors related to PrEP interest among relevant target populations warrant investigation. The aim of this study was to provide an analysis of PrEP interest among men who have sex with men (MSM) in the Netherlands, while taking study recruitment strategies into account. We recruited 154 MSM from an LGBT research panel (AmsterdamPinkPanel) and 272 MSM from convenience sampling. Both samples were part of the Flash! PrEP in Europe Survey and were compared on their PrEP interest, usage intentions, and sexual behavior. We conducted logistic regression analyses to discover variables associated with PrEP interest and intentions. Participants from the AmsterdamPinkPanel were less likely to use PrEP, had less knowledge of PrEP, and were less interested in PrEP than participants from convenience sampling. Significant covariates of PrEP interest were being single, more prior PrEP knowledge, sexual risk behaviors, such as not having used a condom during last sex and having ever used drugs in a sexual context, and not participating in the AmsterdamPinkPanel. Adding the recruitment strategy to the regression increased explained variance on top of predictors already described in the literature. Increased sexual risk behavior is related to increased PrEP interest and it helps to identify PrEP target groups. Recruitment strategies have a substantial impact on findings regarding PrEP interest and usage intentions. This study emphasizes the importance of using multiple strategies for recruiting participants to obtain a more comprehensive view of MSM’s attitudes toward PrEP.

Little is known about Community Health Workers (CHWs) who work in non-clinical settings to provide sexual health support around HIV, viral hepatitis, and other sexually transmitted infections (STIs) to men who have sex with men (MSM) in Europe and neighbouring countries. This article describes for the first time, who CHWs are, and how they contribute to the continuum of services for HIV, viral hepatitis, and other STIs amongst MSM. The first European Community Health Worker Online Survey (ECHOES) developed in the framework of the EU-funded ESTICOM project ( www.esticom.eu ), was available in 16 languages (October 2017-January 2018). Amongst the 1035 persons aged 18 and older reporting CHW activities in the previous 12 months, 28.2% were women, 30.7% were volunteers, 59.2% were men self-defining as gay/homosexual, bisexual or queer (‘peer CHWs’), and most CHWs worked/volunteered in private not-for-profit organisations (86.4%). CHWs involvement in the continuum of services for HIV, viral hepatitis and other STIs was as follows: primary prevention (88.6%), consultation and counselling (58.0%), testing provision (50.6%), linkage to care (49.8%), and treatment and support activities (51.3%). CHWs were also involved in cross-cutting activities such as developing interventions, advocacy, and engaging in research (46.3%). CHWs as a public health workforce contribute to all steps of the continuum of services for HIV, viral hepatitis, and other STIs amongst MSM in Europe. National governments should recognise and support CHWs better in order to make their activities more visible and sustainable, and increase their impact on the continuum of services.

HIV rapid testing algorithms (RTAs) using any two orthogonal rapid tests (RTs) allow for on-site confirmation of infection. RTs vary in performance characteristics therefore the selection of RTs in an algorithm may affect identification of infection, particularly if acute. National HIV Behavioral Surveillance (NHBS) assessed RTAs among men who have sex with men recruited using anonymous venue-based sampling. Different algorithms were evaluated among participants who self-reported never having received a positive HIV test result prior to the interview. NHBS project areas performed sequential or parallel RTs using whole blood. Participants with at least one reactive RT were offered anonymous linkage to care and provided a dried blood spot (DBS) for testing at CDC. Discordant results (RT-1 reactive/RT-2 non-reactive) were tested at CDC with lab protocols modified for DBS. DBS were also tested for HIV-1 RNA (VL) and antiretroviral (ARV) drug levels. Of 6500 RTAs, 238 were RT-1 reactive; of those, 97.1% (231/238) had concordant results (RT-1/RT-2 reactive) and 2.9% (7/238) had discordant results. Five DBS associated with discordant results were available for confirmation at CDC. Four had non-reactive confirmatory test results that implied RT-1 false reactivity; one had ambiguous confirmatory test results which was non-reactive in further testing. Regardless of order and type of RT used, RTAs demonstrated high concordant results in the population surveyed. Additional laboratory testing on DBS following discordant results confirmed no infection. Implementing RTAs in the context of anonymous venue-based HIV testing could be an option when laboratory follow-up is not practicable.

Pre-exposure prophylaxis (PrEP) became publicly available in Quebec for gay, bisexual and other men who have sex with men (GBM) in 2013. We used baseline data from Engage, a cohort of GBM recruited by respondent-driven sampling, to examine patterns of combination HIV prevention use among Montreal GBM since PrEP became available. Latent class analysis, stratified by HIV status, was used to categorize GBM by self-reported use of biomedical and behavioural prevention strategies. Correlates of resulting classes were identified using multinomial logistic regression. Among HIV-negative/unknown GBM (n = 968), we identified four classes: low use of prevention (32%), condoms (40%), seroadaptive behaviour (21%), and biomedical (including PrEP; 7%). Those using prevention (condoms, seroadaptive behaviour, and biomedical) had a higher number of anal sex partners and were more likely to report a recent sexually transmitted infection diagnosis. GBM using biomedical prevention also had a higher level of formal education. Among GBM living with HIV (n = 200), we identified three classes: mainly antiretroviral treatment (ART) with viral suppression (53%), ART with viral suppression and condoms (19%), and ART with viral suppression and seroadaptive behaviour (18%). Again, the number of anal sex partners was higher among those using condoms and seroadaptive behaviours. Our findings show antiretroviral-based prevention, either alone or in combination with other strategies, is clearly a component of the HIV prevention landscape for GBM in Montreal. Nevertheless, PrEP uptake remains low, and there is a need to promote its availability more widely.

This study explored factors associated with interest in taking PrEP among men who have sex with men (MSM) attending HIV testing venues in Sweden. Data from 658 HIV-negative respondents, surveyed by a questionnaire at six sites, were analyzed descriptively and by univariable and multivariable logistic regression. A total of 453 (68.8%) of the respondents expressed interest in taking PrEP. Reporting self-perceived risk of HIV acquisition as moderate or high, reporting ≥ 5 partners for condomless anal intercourse during the past year, and reporting hard drug use during the past year were independently associated with interest in taking PrEP. However, an aggregated variable of self-reported rectal gonorrhea, rectal chlamydia, or syphilis infection during the past year was not associated with interest in taking PrEP. Overall, Swedish MSM were well-informed regarding PrEP, and interest in taking PrEP was positively associated with sexual risk indicators.

We implemented a pilot home HIV self-testing program one week after a stay-home order for SARS-CoV2 was enacted in Oregon. We advertised the program on a geospatial networking app and community partner websites targeting men who have sex with men; nine percent of web visits resulted in an order. Over 70% of the kits initially allotted to the program were ordered in the first 24 h of launch. One-third of participants had never tested for HIV. We found enthusiasm for discreet, free, home-based testing and uncovered an unmet need for HIV testing as clinical and outreach programs shuttered in Oregon.

Pre-exposure prophylaxis (PrEP) is an evidence-based new biomedical HIV prevention intervention, which involves the pre-emptive use of daily (or event-based) antiretroviral drugs, to reduce risk of HIV acquisition if exposed. PrEP has recently been positioned as an integral prevention tool to reduce HIV acquisition risk among men who have sex with men (MSM) at country-level and within global prevention strategies. Given this global scale up of PrEP, we conducted a scoping review of extant international literature documenting service related perspectives, models and lessons learnt in PrEP programming for MSM. A systematic search of literature was conducted, and restricted to English language records in the timeframe 2008 to February 2019. Eligibility criteria centered on whether studies broadly described PrEP programming and service delivery for MSM as well as health communication. Following exclusion of ineligible records and removal of duplicates, 84 records were charted and thematically analysed according to scoping review methods. Four themes emerged from the thematic analysis of data; ‘PrEP service aspects, settings and staff’; ‘PrEP prescriber experiences, therapeutic alliance and care planning’; ‘PrEP adherence within formal service structures’; and ‘Multi-disciplinary and innovative PrEP care pathways’. The review highlights the complexities in providing optimal PrEP services for MSM by mapping and illustrating the importance of understanding the informal and formal routes to PrEP use among this HIV risk population; the barriers to uptake; the requirement for the presence of a positive therapeutic alliance between patient and prescriber in supporting patient initiation and adherence to PrEP regimes; and the need for availability in different culturally and ethnically sensitive models of PrEP service delivery according to low to high risk groups within the MSM communities.

Syphilis and HIV among gay, bisexual and other men who have sex with men (MSM) are syndemic suggesting current prevention strategies are not effective. Sex partner meeting places and their networks may yield effective and optimal interventions. From 2009 to 2017, 57 unique venues were reported by > 1 MSM and 7.0% (n = 4), 21.1% (n = 12) and 71.9% (n = 41) were classified as syphilis, HIV or co-diagnosed venues, respectively. Forty-nine venues were connected in one main network component with four online, co-diagnosis venues representing 51.6% of reports and the highest degree and eigenvector centralities. In a sub-analysis during a local syphilis epidemic, the proportion of venues connected in the main component increased 38.7% (61.5% to 86.4%); suggesting increasing overlap in syphilis and HIV transmission and density of the venue network structure over time. This network analysis may identify the optimal set of venues for tailored interventions. It also suggests increasing difficulty of interrupting network transmission through fragmentation.

Background Men who have sex with men are a risk group for anal human papillomavirus (HPV) and anal cancer. Australia introduced a universal school-based HPV vaccination program in 2013. Self-reported HPV vaccination status has been widely used in clinical and research settings, but its accuracy is understudied. Objective We aimed to examine the accuracy of self-reported HPV vaccination status among gay and bisexual adolescent males. Methods We included 192 gay and bisexual males aged 16-20 years from the Human Papillomavirus in Young People Epidemiological Research 2 (HYPER2) study in Melbourne, Australia. All participants had been eligible for the universal school-based HPV vaccination program implemented in 2013 and were asked to self-report their HPV vaccination status. Written informed consent was obtained to verify their HPV vaccination status using records at the National HPV Vaccination Program Register and the Australian Immunisation Register. We calculated the sensitivity, specificity, positive predictive value, and negative predictive value of self-reported HPV vaccination status. Results The median age of the 192 males was 19 (IQR 18-20) years. There were 128 males (67%) who had HPV vaccination records documented on either registry. Self-reported HPV vaccination had a sensitivity of 47.7% (95% CI 38.8%-56.7%; 61/128), a specificity of 85.9% (95% CI 75.0%-93.4%; 55/64), a positive predictive value of 87.1% (95% CI 77.0%-93.9%; 61/70), and a negative predictive value of 45.1% (95% CI 36.1%-54.3%; 55/122). Conclusions Self-reported HPV vaccination status among Australian gay and bisexual adolescent males underestimates actual vaccination and may be inaccurate for clinical and research purposes.

Background New innovative technologies, such as mobile apps, have been developed to increase pre-exposure prophylaxis (PrEP) adherence and the use of log sex diaries. The contiguity of mobile apps reduces the recall bias that generally affects reported condom and PrEP use. However, none of the currently used mobile apps were designed for event-driven PrEP users, and few studies have demonstrated the potential usage of sex diary data to facilitate the understanding of the different HIV risks among heterogeneous profiles of sex diaries and PrEP use. Objective We aim to discriminate the heterogeneous profiles of sex events and PrEP use and examine the risk of condomless anal sex among different types of sex events. Methods We recruited 35 adult men who have sex with men from two medical centers in Taiwan since May 2020 and followed up for four months. Participants were on PrEP or willing to take PrEP. They were asked to log their sex events, PrEP use, and dosing regimens on a mobile app to improve their PrEP adherence. Latent class analysis was used to distinguish profiles of sex events and PrEP use. Indicators included correct intake of PrEP for each sex event, participants’ sexual positioning, partner’s HIV status, and age. Results A total of 551 sex events were classified into three classes by latent class analysis: PrEP nonadherent flip-flopping (234/551, 42%), PrEP imperfect-adherent power bottoming (284/551, 52%), and PrEP adherent serodiscordant topping (33/551, 6%). “PrEP nonadherent flip-flopping” sex events were more likely to involve condomless anal sex than “PrEP imperfect-adherent power bottoming” (OR 1.83, 95% CI 1.03-3.25) after considering random intercepts for individuals, and this class needed to increase their PrEP adherence and use of condoms. “PrEP imperfect-adherent power bottoming” realized their own risk and packaged PrEP with condoms to protect themselves. Up to 99% (32/33) of sex events in “PrEP adherent serodiscordant topping” were protected by PrEP, but all of the sex events in this group were condomless. Conclusions Using the sex diary data could advance the capacity to identify high-risk groups. HIV prevention strategy should be more flexible and combine PrEP with condom use for future HIV prevention.

Men who have sex with men (MSM), regardless of HIV infection status, have an intestinal microbiome that is compositionally distinct from men who have sex with women (MSW) and women. We recently showed HIV-negative MSM have elevated levels of intestinal CD4+ T cells expressing CCR5, a critical co-receptor for HIV. Whether elevated expression of CCR5 is driven by the altered gut microbiome composition in MSM has not been explored. Here we used in vitro stimulation of gut Lamina Propria Mononuclear Cells (LPMCs) with whole intact microbial cells isolated from stool to demonstrate that fecal bacterial communities (FBCs) from HIV-positive/negative MSM induced higher frequencies of CCR5+ CD4+ T cells compared to FBCs from HIV-negative MSW and women. To identify potential microbial drivers, we related the frequency of CCR5+ CD4+ T cells to the abundance of individual microbial taxa in rectal biopsy of HIV-positive/negative MSM and controls, and Holdemanella biformis was strongly associated with increased frequency of CCR5+ CD4+ T cells. We used in vitro stimulation of gut LPMCs with the type strain of H. biformis, a second strain of H. biformis and an isolate of the closely related Holdemanella porci , cultured from either a HIV-positive or a HIV-negative MSM stool. H. porci elevated the frequency of both CCR5+ CD4+ T cells and the ratio of TNF-α/IL-10 Genomic comparisons of the 3 Holdemanella isolates revealed unique cell wall and capsular components, which may be responsible for their differences in immunogenicity. These findings describe a novel mechanism potentially linking intestinal dysbiosis in MSM to HIV transmission and mucosal pathogenesis.

Late HIV diagnosis remains frequent among the gay, bisexual, and other men who have sex with men (GBMSM) population across Europe. HIV self-sampling could help remove barriers and facilitate access to testing for this high-risk population. We assessed the capacity of HIV self-sampling to increase the testing frequency among GBMSM living in Denmark, Germany, Greece, Portugal, Romania, and Spain, and evaluated the role of new technologies in the result communication phase. We analyzed a convenience sample of 5019 GBMSM with prior HIV testing experience who were recruited during 2016 through gay dating websites. We estimated the proportion of GBMSM who reported that the availability of self-sampling would result in an increase of their current testing frequency. We constructed a Poisson regression model for each country to calculate prevalence ratios and 95% CIs of factors associated with an increase of testing frequency as a result of self-sampling availability. Overall, 59% (between country range 54.2%-77.2%) of the participants considered that they would test more frequently for HIV if self-sampling was available in their country. In the multivariate analysis, the increase of testing frequency as a result of self-sampling availability was independently associated with reporting a higher number of unprotected anal intercourse events in all countries except for Greece. Independent associations were also observed among GBMSM who were not open about their sex life in Germany, Greece, Portugal, and Spain; those with a lower number of previous HIV tests in Denmark, Greece, Portugal, and Spain; and for those that took their last test more than 3 months previously in Germany, Portugal, Romania, and Spain. In addition, 58.4% (range 40.5%-73.6%) of the participants indicated a preference for learning their result through one-way interaction methods, mainly via email (25.6%, range 16.8%-35.2%) and through a secure website (20.3%, range 7.3%-23.7%). Almost two thirds (65%) of GBMSM indicated preferring one of these methods even if the result was reactive. Availability of HIV self-sampling kits as an additional testing methodology would lead to a much-needed increase of testing frequency, especially for the hidden, high-risk, and undertested GBMSM population. Online-based technologies without any personal interaction were preferred for the communication of the results, even for reactive results. This study was supported by the Consumers, Health and Food Executive Agency (CHAFEA: 20131101) and Acción Estratégica Intramural (PI17CIII/00037). The funding sources were not involved in the study design; in the collection, analysis, and interpretation of data; in the writing of the report; or in the decision to submit the paper for publication.

This paper presents data from a recent cross-sectional survey of gay, bisexual and other men who have sex with men (GBMSM) in the US, to understand changes in sexual behavior and access to HIV prevention options (i.e. condoms and pre-exposure prophylaxis (PrEP)) during the COVID-19 lockdown period. The Love and Sex in the Time of COVID-19 survey was conducted online from April to May, 2020. GBMSM were recruited through advertisements featured on social networking platforms, recruiting a sample size of 518 GBMSM. Analysis considers changes three in self-reported measures of sexual behavior: number of sex partners, number of anal sex partners and number of anal sex partners not protected by pre-exposure prophylaxis (PrEP) or condoms. Approximately two-thirds of the sample reported that they believed it was possible to contract COVID-19 through sex, with anal sex reported as the least risky sex act. Men did not generally feel it was important to reduce their number of sex partners during COVID-19, but reported a moderate willingness to have sex during COVID-19. For the period between February and April-May 20,202, participants reported a mean increase of 2.3 sex partners during COVID-19, a mean increase of 2.1 anal sex partners (range - 40 to 70), but a very small increase in the number of unprotected anal sex partners. Increases in sexual behavior during COVID-19 were associated with increases in substance use during the same period. High levels of sexual activity continue to be reported during the COVID-19 lockdown period and these high levels of sexual activity are often paralleled by increases in substance use and binge drinking. There is a clear need to continue to provide comprehensive HIV prevention and care services during COVID-19, and telehealth and other eHealth platforms provide a safe, flexible mechanism for providing services.

BACKGROUND In the United States, young cisgender men who have sex with men (YMSM), young transgender women (YTW), and gender nonconforming (GNC) youth face elevated rates of HIV infection. However, racial and ethnic disparities in adolescent HIV infection cannot be attributed to individual-level factors alone and are situated within larger social and structural contexts that marginalize and predispose sexual and gender minority youth of color to HIV. Addressing broader ecological factors that drive transmission requires interventions that focus on the distal drivers of HIV infection, including violence exposure, housing, food insecurity, educational attainment, and employment. Given the ways that economic instability may make YMSM, YTW, and GNC youth of color vulnerable to HIV exposure, this study focuses on employment as an HIV prevention intervention. More specifically, the intervention, called Work2Prevent (W2P), targets economic stability through job readiness and employment as a means of preventing behaviors and factors associated with adolescent and young adult HIV, such as transactional sex work and homelessness. The intervention was adapted from iFOUR, an evidence-based employment program for HIV-positive adults in phase 1 of this study, and pilot tested in a university-based setting in phase 2. OBJECTIVE This paper aims to describe the protocol for the community-based test phase of W2P. The purpose of this phase was to pilot test a tailored, theoretically informed employment intervention program among YMSM, YTW, and GNC youth of color within a lesbian, gay, bisexual, transgender, and queer (LGBTQ) community setting. METHODS The employment intervention was pilot tested using a single-arm pretest-posttest trial design implemented among a sample of vulnerable YMSM, YTW, and GNC youth of color using services within a community-based LGBTQ center. Assessments will examine intervention feasibility, acceptability, and preliminary estimates of efficacy. RESULTS Phase 3 of W2P research activities began in May 2019 and was completed in December 2019. Overall, 41 participants were enrolled in the community-based pilot. CONCLUSIONS This study will assess intervention feasibility and acceptability in the target populations and determine preliminary efficacy of the intervention to increase employment and reduce vulnerability to HIV when implemented in a community-based setting serving LGBTQ youth of color. Testing the intervention in a community setting is an opportunity to evaluate how recruitment, retention, and other outcomes are impacted by delivery in a venue akin to where this intervention could eventually be used by nonresearchers. If W2P demonstrates feasibility and acceptability, a larger multisite trial implemented in multiple community settings serving YMSM, YTW, and GNC youth of color is planned.

BACKGROUND Cisgender men who have sex with men (MSM) and transgender people (TGP) who use methamphetamine are disproportionately impacted by HIV acquisition. Pre-exposure prophylaxis (PrEP) is highly effective at preventing HIV, and interventions that support PrEP persistence and adherence should be evaluated among MSM and TGP who use methamphetamine. OBJECTIVE We conducted formative work to inform the development of text messaging and peer navigation interventions to support PrEP persistence and adherence among MSM and TGP who use methamphetamine. In this paper, we describe how the findings from these focus groups and interviews were used to refine the study interventions and protocol for the Hit Me Up! study (HMU!; HIV Prevention in Methamphetamine Users). METHODS Between October 2017 and March 2018, we conducted two focus groups and three in-depth interviews with MSM and TGP who use methamphetamine or who have worked with people who use methamphetamine. During these formative activities, we asked participants about their opinions on the proposed interventions, education and recruitment materials, and study design. We focused on how we could develop peer navigation and text messaging interventions that would be culturally appropriate and acceptable to MSM and TGP who use methamphetamine. Transcripts were reviewed by two authors who performed a retrospective content analysis to describe which specific opinions and recommendations influenced protocol development and the refinement of the interventions. RESULTS Overall, participants thought that MSM and TGP would be interested in participating in the study, although they expected recruitment and retention to be challenging. Participants thought that the peer navigator should be someone who is nonjudgmental, has experience with people who use methamphetamine, and is patient and flexible. There was consensus that three text messages per day were appropriate, adherence reminders should be straightforward, all messages should be nonjudgmental, and participants should be able to tailor the timing and content of the text messages. These suggestions were incorporated into the study interventions via the hiring and training process and into the development of the text library, platform selection, and customizability of messages. CONCLUSIONS It is important to include the opinions and insights of populations most impacted by HIV to develop PrEP interventions with the greatest chance of success. Our formative work generated several recommendations that were incorporated into the interventions and protocol development for our ongoing study.

Background Men who have sex with men (MSM) are a key group for HIV interventions in Malawi considering their high HIV prevalence (17.5% compared to 8.4% among men in the general population). The use of oral preexposure prophylaxis (PrEP) presents a new opportunity for MSM to be protected. We present the findings from a qualitative assessment designed to assess awareness of and willingness and barriers to using PrEP among MSM in Malawi. Objective The 3 main objectives of this assessment were to determine: (1) awareness of PrEP, (2) factors that influence willingness to use PrEP, and (3) potential barriers to PrEP use and adherence among MSM in order to guide the design and implementation of a PrEP program in Malawi. Methods Ahead of the introduction of PrEP in Malawi, a qualitative study using in-depth interviews (IDIs) and focus group discussions (FGDs) was conducted in October 2018 in Blantyre, Lilongwe, and rural districts of Mzimba North and Mangochi. With support of members of the population, study participants were purposively recruited from 4 MSM-friendly drop-in centers where MSM receive a range of health services to ensure representativeness across sites and age. Participants were asked what they had heard about PrEP, their willingness to use PrEP, their barriers to PrEP use, and their preferences for service delivery. The data were analyzed using a thematic content analysis framework that was predetermined in line with objectives. Results A total of 109 MSM were interviewed—13 through IDIs and 96 through FGDs. Most participants were aware of PrEP as a new HIV intervention but had limited knowledge related to its use. However, the majority were willing to use it and were looking forward to having access to it. IDI participants indicated that they will be more willing to take PrEP if the dosing frequency were appropriate and MSM were involved in information giving and distribution of the drug. FGD participants emphasized that places of distribution and characteristics of the service provider are the key factors that will affect use. Knowing the benefits of PrEP emerged as a key theme in both the IDIs and FGDs. Participants highlighted barriers that would hinder them from taking PrEP such as side effects which were cited in IDIs and FGDs. Key factors from FGDs include cost, fear of being outed, drug stockouts, fear of being known as MSMs by wives, and lack of relevant information. FGDs cited stigma from health care workers, forgetfulness, and community associated factors. Conclusions Despite having inadequate knowledge about PrEP, study participants were largely willing to use PrEP if available. Programs should include an effective information, education, and communication component around their preferences and provide PrEP in MSM-friendly sites.

We investigated the longitudinal relationship between erectile dysfunction (ED) drug use with behavioral factors, including substance use and sexual activities in men who have sex with men from the Multicenter AIDS Cohort Study during 1998–2016 (n = 1636). We used a bivariate random-intercept model to evaluate ED drug use along with other behavioral factors to assess relationships between the two outcomes over time on a population level and also at the individual level. Average ED drug use among men who have sex with men (MSM) with HIV was positively correlated with average use of marijuana (r = .19), poppers (r = .27), and stimulants (r = .25). In this group, testosterone use (r = .32), multiple partners (r = .41), insertive anal intercourse with condom (r = .40), and insertive anal intercourse without condom (r = .43) all showed moderate correlations over time with average ED use (p r = .19) and stimulant use (r = .22) being positively correlated with average ED drug use, and were also correlated with having multiple partners (r = .36), insertive anal intercourse with condom (r = .22), and insertive anal intercourse without condom (r = .18) over time. Positive within-individual associations between ED drug use and multiple partners and insertive anal intercourse with and without condom were observed regardless of HIV serostatus. This study showed that MSM who reported use of ED drugs were also, on average, more likely to use recreational drugs and engage in sexual activities, such as having multiple partners and insertive anal intercourse. Within individuals, average ED drug use was also positively correlated with sexual behaviors.

Masturbation is a common sexual practice in men, and saliva is often used as a lubricant during masturbation by men who have sex with men. However, the role of saliva use during masturbation in the transmission of chlamydia is still unclear. We developed population-level, susceptible-infected-susceptible compartmental models to explore the role of saliva use during masturbation on the transmission of chlamydia at multiple anatomical sites. In this study, we simulated both solo masturbation and mutual masturbation. Our baseline model did not include masturbation but included transmission routes (anal sex, oral-penile sex, rimming, kissing and sequential sexual practices) we have previously validated (model 1). We added masturbation to model 1 to develop the second model (model 2). We calibrated the model to five clinical datasets separately to assess the effects of masturbation on the prevalence of site-specific infection. The inclusion of masturbation (model 2) significantly worsened the ability of the models to replicate the prevalence of C. trachomatis. Using model 2 and the five data sets, we estimated that saliva use during masturbation was responsible for between 3.9% [95% confidence interval (CI) 2.0–6.8] and 6.2% (95% CI 3.8–10.5) of incident chlamydia cases at all sites. Our models suggest that saliva use during masturbation is unlikely to play a major role in chlamydia transmission between men, and even if it does have a role, about one in seven cases of urethral chlamydia might arise from masturbation.

Background In Burundi, given the low testing numbers among key populations (KPs), peer-assisted HIV self-testing (HIVST) was initiated for female sex workers (FSWs), men who have sex with men (MSM), and transgender people to provide another testing option. HIVST was provided by existing peer outreach workers who were trained to provide support before, during, and after the administration of the test. People who screened reactive were referred and actively linked to confirmatory testing, and those confirmed positive were linked to treatment. Standard testing included HIV testing by clinical staff either at mobile clinics in the community or in facilities. Objective This study aims to improve access to HIV testing for underserved KPs, improve diagnoses of HIV serostatus among key populations, and link those who were confirmed HIV positive to life-saving treatment for epidemic control. Methods A descriptive analysis was conducted using routine programmatic data that were collected during a 9-month implementation period (June 2018 to March 2019) for peer-assisted HIVST among FSWs, MSM, and transgender people in 6 provinces where the US Agency for International Development–and US President’s Emergency Plan for AIDS Relief–funded LINKAGES (Linkage across the Continuum of HIV Services for KP Affected by HIV) Burundi project was being implemented. Chi-square tests were used to compare case-finding rates among individuals who were tested through HIVST versus standard testing. Multivariable logistic regression was performed to assess factors that were independently associated with HIV seropositivity among FSWs and MSM who used HIVST kits. Results A total of 2198 HIVST kits were administered (FSWs: 1791/2198, 81.48%; MSM: 363/2198, 16.52%; transgender people: 44/2198, 2%). HIV seropositivity rates from HIVST were significantly higher than those from standard testing for FSWs and MEM and nonsignificantly higher than those from standard testing for transgender people (FSWs: 257/1791, 14.35% vs 890/9609, 9.26%; P8 clients per week (adjusted odds ratio 1.3, 95% CI 1.0-1.8) were independently associated with HIV seropositivity. Conclusions The results demonstrate the potential effectiveness of HIVST in newly diagnosing underserved KPs and linking them to treatment.

Chemsex is an escalating public health issue among men who have sex with men, with potentially severe somatic and psychiatric consequences. Given the limited knowledge and lack of treatment recommendations available in this area, we proposed the use of noninvasive brain stimulation in order to reduce problematic chemsex behavior. This is the first open-label case report of a positive effect of transcranial direct current stimulation (tDCS) in a patient who was complaining of severe chemsex addiction. Total disappearance of chemsex behavior occurred after 5 days of daily sessions of right prefrontal cortex stimulation and did not return after 8 months of follow-up. The strengthening of dorsolateral prefrontal cortex activity may have modulated limbic pathways and reduced incentive salience and craving of both sexual addiction and concomitant illicit drug use. .El Chemsex es un problema de salud pública creciente entre los hombres homosexuales, con consecuencias somáticas y psiquiátricas potencialmente graves. Dados el conocimiento limitado y la falta de recomendaciones de tratamiento disponibles en esta área, propusimos el uso de estimulación cerebral no invasiva para reducir los comportamientos problemáticos relacionados con el chemsex. Este es el primer informe de caso clínico abierto que muestra un efecto positivo de la estimulación transcraneal de corriente directa (tDCS) en un paciente que se quejaba de una adicción grave al chemsex. La desaparición total de los comportamientos relacionados con el chemsex se produjo después de 5 días de sesiones diarias de estimulación de la corteza prefrontal derecha y no regresó después de 8 meses de seguimiento. El aumento de la actividad de la corteza prefrontal dorsolateral puede haber modulado las vías límbicas y reducido la prominencia del incentivo y los antojos asociados tanto con la adicción sexual como con el uso concurrente de drogas ilícitas.Le chemsex est un problème de santé publique croissant chez les hommes ayant des relations homosexuelles, aux conséquences somatiques et psychiatriques potentiellement graves. Compte tenu des connaissances limitées et du manque de recommandations de traitement disponibles dans ce domaine, nous avons proposé l'utilisation de stimulation cérébrale non invasive afin de réduire les comportements problématiques liés au chemsex. C'est le premier rapport de cas clinique ouvert montrant un effet positif du courant continu transcrânien stimulation (tDCS) chez un patient qui se plaignait d'une grave dépendance au chemsex. La disparition totale des comportements liés au chemsex est survenue après 5 jours de séances quotidiennes de stimulation du cortex préfrontal droit et n'est pas revenue après 8 mois de suivi. Le renforcement de l'activité du cortex préfrontal dorsolatéral peut avoir modulé les voies limbiques et réduit la saillance incitative et les état de manque liés tant à la dépendance sexuelle qu’à l’usage concomitant de drogues illicites.

Background A substantial proportion of people living with HIV (PLHIV) present for care with advanced HIV disease (AHD), which may result in difficulty reaching the “90–90–90” target to end AIDS in 2030. We assessed the risk of AHD for different transmission routes to summarize the evidence for priority prevention strategies for key populations. Methods Observational studies published before September 10th, 2019 in the PubMed, EMBASE, Web of Science and Chinese electronic databases were analysed. The outcomes of interest were the number of PLHIV and AHD patients and their associated transmission routes. We assessed the risk of AHD among the different transmission routes using the multi-armed network meta-analysis based on the Bayesian method. The associations between AHD and regional policies for sex work and compulsory drug treatment were estimated using ecological linear regression. Findings One hundred and one articles were included, covering 1,297,872 PLHIV with 478,830 patients who developed AHD. The network analysis revealed that among PLHIV, heterosexual contact was associated with the highest risk of AHD, followed by injection drug use (odds ratio [OR]=0•56, 95% credible interval [CrI] 0•47–0•68), and men who have sex with men (OR=0•54, 95% CrI 0•46–0•63). Regions that criminalized sex work and compulsory drug treatment had higher risks for AHD than those that did not. Interpretation Our findings suggest HC is at a higher risk of AHD compared to IDU and MSM. This justifies the need to expand prevention campaigns and maintain efforts to increase HIV testing in the heterosexual population.

Our aim was to better understand Human Papillomavirus (HPV) vaccine acceptance among Mexican adults including people with and without HIV, cisgender men who have sex with men (MSM) or with women (MSW), cisgender and transgender women. A computer-assisted, self-administered questionnaire was completed by healthcare users and participants recruited through community organizations, and the first dose of the quadrivalent HPV vaccine was offered at no cost at a large sexual health clinic in Mexico City, from May to December 2018. Socio-demographic characteristics and factors associated with HPV vaccine acceptance were analyzed using logistic regression. The sample of 1915 participants included 1341 cisgender men (70.9%, 1247 MSM and 94 MSW), 396 (20.7%) cisgender women and 178 (9.3%) transwomen; 615 people (32.1%) were HIV positive. Uptake of the HPV vaccine was higher in men and transwomen (91.5% and 87%, respectively) than among cisgender women (81.8%; p

Background: Available agents within the integrase strand-transfer inhibitor (INSTI) class have been shown to lead to a faster decay in viral load than other regimens. Therefore, we estimated the potential reduction in HIV transmission risk among antiretroviral-naïve individuals initiating on INSTI-based antiretroviral therapy (ART), focusing on the gay, bisexual and other men who have sex with men (gbMSM) population and various degrees of sexual activity. Methods: Using two mathematical models that estimate the HIV transmission risk corresponding to different viral loads, we estimated the average probability of HIV transmission per risky contact for gbMSM during the six months post-ART initiation, stratified by stage of HIV infection, viral load at ART initiation and type of first-line ART (i.e., INSTI or non-INSTI-based ART). This study focused individuals who initiated ART between 2011 and 2016 with at least one year of follow-up in British Columbia, Canada. Findings: Time to first virologic suppression for INSTI-based regimens was 21.4 days (95% credible interval (CI) 19.9–23.2), compared to 58.6 days (95% CI 54.1–62.2) for non-INSTI regimens. We showed that INSTI-based regimens could reduce the HIV transmission risk by at least 25% among those with viral load ≥5 log10 copies/mL at ART initiation. Interpretation: Initiating ART on INSTI-based regimens has the potential to reduce HIV transmission risk among individuals with high baseline viral load levels, especially among those with high levels of sexual activity.

Background Encouraging consistent use of pre-exposure prophylaxis (PrEP) is essential for reducing HIV incidence, particularly among gay, bisexual, and other men who have sex with men (GBM), and especially those who engage in heavy drinking. Although practice guidelines recommend providing adherence counseling to PrEP patients, clinics and providers may not have the resources or expertise to provide it. Internet-facilitated interventions have been shown to improve HIV prevention outcomes, including medication and care adherence. Game Plan is a website we created to help users make a tangible plan for reducing their HIV risk. We designed additional components of Game Plan to address key individual level barriers to PrEP use. Objective The aim of this mixed methods research is to test the usability and user experience of these components with intended users: GBM who drink heavily and are on PrEP. Methods In study 1 (usability), we completed a detailed individual interview in which participants (n=10) walked through a prototype of the website, thinking aloud as they did, and completed a follow-up interview and web-based survey afterward. Study 2 (user experience) involved providing participants (n=40) with a link to the prototype website to explore on their own and asking them to complete the same follow-up survey afterward. Qualitative data were analyzed using thematic analysis, and descriptive statistics were used to analyze quantitative data. Results Users in both studies gave the website excellent ratings for usability, overall satisfaction, and quality, and most often described the site as informative, helpful, and supportive. Users also rated the site’s content and feel as respectful of them and their autonomy, empathetic, and they stated that it conveyed confidence in their ability to change. The study 1 interviews highlighted the importance of the website’s esthetics to the participants’ engagement with it and its credibility in prompting genuine reflection. Conclusions GBM who reported heavy drinking and used PrEP generally found a website focused on helping them to create a plan to use PrEP consistently to be helpful. Adopting user-centered design methods and attending to the esthetics of mobile health interventions are important steps toward encouraging engagement and reducing at-risk behaviors.

Background: Monitoring progress towards the UNAIDS ‘first 90’ target requires accurate estimates of levels of diagnosis among people living with HIV (PLHIV). Knowledge of HIV-positive status is often estimated using self-report, potentially leading to information bias. We aimed to systematically review the evidence and quantify levels of under-reporting of knowledge of HIV-positive status among PLHIV using objective proxies of knowledge of status. Methods: Databases were searched for studies providing self-reported and biological/clinical markers of prior knowledge of HIV-positive status among laboratory-confirmed PLHIV. PLHIV with antiretroviral drugs detected, viral load suppression, or prior diagnosis in medical records, but not reporting being HIV-positive, were classified as under-reporting known HIV-positive status. Random-effects models were used to derive pooled estimates of the proportion under-reporting known HIV-positive status. Possible sources of heterogeneity were investigated using sub-group analyses. Findings: Thirty-two independent estimates from 26 studies including 41,465 PLHIV were included. Most studies were conducted in North America (number of estimates [Ne]=12) or Africa [Ne=14], in the general population [Ne=10] or among men who have sex with men [MSM; Ne=10]). The pooled proportion under-reporting known HIV-positive status among all PLHIV was 20% (95% confidence interval: 13%–26%, I2=99%). In sub-group analysis, under-reporting was higher among MSM (32%, Ne=10) compared to the general population (9%, Ne=10). In the subset of North American studies with data stratified by race, under-reporting was higher among Black (18%, Ne=5) than non-Black (3%, Ne=3; p=0.026) individuals. Interestingly, the absolute magnitude of under-reporting was not associated with the level of self-reporting (slope 0.12, p=0.168). Interpretation: Substantial under-reporting of knowledge of HIV-positive status was found, particularly among MSM, and among Black PLHIV in North America. Supplementing self-reported data with biological/clinical proxies where possible may improve the validity of the ‘first 90’ estimates.

Background HIV disproportionately affects young Black men who have sex with men (YBMSM) in the United States. eHealth holds potential for supporting linkage and engagement in HIV prevention and care and the delivery of HIV information to YBMSM. Objective This study aims to investigate HIV information acquisition and use among YBMSM who use the internet. Methods A web-based self-administered survey and semistructured interviews were conducted. The survey findings informed the development of the interview guide. Descriptive statistics were used to characterize the survey sample, and interview data were analyzed thematically using modified grounded theory methodologies. Results Among the internet sample (N=83), the average age was 29.2 (SD 3.5) years, 41% (n=34) of participants self-reported living with HIV, 43% (n=36) were HIV-negative, and 15% (n=13) were unsure of their HIV status. Most participants (n=79, 95%) acquired HIV information through the internet while using a mobile phone. Web-based HIV information was intentionally sought from consumer health information websites (n=31, 37%), government health information websites (n=25, 30%), and social media (n=14, 17%). Most men incidentally acquired HIV information via advertisements on social media sites and geospatial dating apps (n=54, 65%), posts on social media sites from their web-based social ties (n=44, 53%), and advertisements while browsing the internet (n=40, 48%). Although the internet is the top source of HIV information, health care providers were the most preferred (n=42, 50%) and trusted (n=80, 96%) source of HIV information. HIV information was used to facilitate the use of HIV prevention and care services. The qualitative sample included YBMSM across a range of ages and at different points of engagement in HIV prevention and care. Qualitative findings included the importance of the internet as a primary source of HIV information. The internet was used because of its ease of accessibility, because of its ability to maintain anonymity while searching for sensitive information, and to mitigate intersecting stigmas in health care settings. Participants used HIV information to assess their risk for HIV and AIDS, support their skill building for HIV prevention, inform patient–doctor communication, and learn about HIV prevention and treatment options. Men expressed concerns about their diminishing access to online spaces for HIV information exchange among YBMSM because of censorship policies on social media sites and the stigmatizing framing and tone of mass media HIV-prevention advertisements encountered while using the internet. Conclusions YBMSM in this sample had high utilization of eHealth for HIV information acquisition and use but diminished access to their preferred and most trusted source of HIV information: health care providers. Future eHealth-based HIV interventions culturally tailored for YBMSM should aim to reduce intersectional stigma at the point of care and support patient–provider communication. The findings demonstrate the need for community-informed, culturally tailored HIV messaging and online spaces for informational support exchange among YBMSM.

Background Social media networks provide an abundance of diverse information that can be leveraged for data-driven applications across various social and physical sciences. One opportunity to utilize such data exists in the public health domain, where data collection is often constrained by organizational funding and limited user adoption. Furthermore, the efficacy of health interventions is often based on self-reported data, which are not always reliable. Health-promotion strategies for communities facing multiple vulnerabilities, such as men who have sex with men, can benefit from an automated system that not only determines health behavior risk but also suggests appropriate intervention targets. Objective This study aims to determine the value of leveraging social media messages to identify health risk behavior for men who have sex with men. Methods The Gay Social Networking Analysis Program was created as a preliminary framework for intelligent web-based health-promotion intervention. The program consisted of a data collection system that automatically gathered social media data, health questionnaires, and clinical results for sexually transmitted diseases and drug tests across 51 participants over 3 months. Machine learning techniques were utilized to assess the relationship between social media messages and participants' offline sexual health and substance use biological outcomes. The F1 score, a weighted average of precision and recall, was used to evaluate each algorithm. Natural language processing techniques were employed to create health behavior risk scores from participant messages. Results Offline HIV, amphetamine, and methamphetamine use were correctly identified using only social media data, with machine learning models obtaining F1 scores of 82.6%, 85.9%, and 85.3%, respectively. Additionally, constructed risk scores were found to be reasonably comparable to risk scores adapted from the Center for Disease Control. Conclusions To our knowledge, our study is the first empirical evaluation of a social media–based public health intervention framework for men who have sex with men. We found that social media data were correlated with offline sexual health and substance use, verified through biological testing. The proof of concept and initial results validate that public health interventions can indeed use social media–based systems to successfully determine offline health risk behaviors. The findings demonstrate the promise of deploying a social media–based just-in-time adaptive intervention to target substance use and HIV risk behavior.

The aim of this qualitative study was to explore the experiences of informal PrEP users regarding access to PrEP and PrEP-related healthcare, community responses, sexual behavior and well-being. We interviewed 30 men who have sex with men (MSM) in semi-structured online interviews between March and August 2018. Interviews were analyzed using interpretive description. Informal PrEP users were well informed about the use of PrEP, but sometimes did not make use of renal testing. Participants reported a lack of PrEP knowledge among healthcare providers, which limited their access to PrEP and put them at risk, as they received incorrect information. Although some participants reported negative reactions from potential sex partners, most received positive reactions and were sometimes seen as more desirable sex partners. PrEP healthcare services should not only be accessible to formal PrEP users, but also to PrEP users who procure PrEP informally.

Background HIV self-testing (HIVST) kits are common in key sexually active populations. Direct secondary distribution of HIVST kits (DSDHK) is effective in improving the uptake of HIVST. However, there are concerns about the various limitations of DSDHK, including limited geographic reach, payment problems, and need for face-to-face interactions. Objective In this study, we aim to evaluate the feasibility and characteristics of indirect secondary distribution of HIVST kits (ISDHK) via WeChat (distributing HIVST application links and follow-up HIVST kits to partners) among men who have sex with men (MSM). Methods From October 2017 to September 2019, an HIVST recruitment advertisement was disseminated on the WeChat social media platform to invite MSM to apply for the HIVST kits (referred to as index participants [IPs]). All MSM participants were encouraged to distribute the HIVST application link to their friends and sexual partners (referred to as alters) through their social networks. All the alters were further encouraged to continue distributing the HIVST application link. All participants paid a deposit (US $7), which was refundable upon completion of the questionnaire, and uploaded the test results via a web-based survey system. Results A total of 2263 MSM met the criteria and successfully applied for HIVST. Of these, 1816 participants returned their HIVST results, including 1422 (88.3%) IPs and 394 (21.7%) alters. More alters had condomless anal intercourse, a higher proportion of them had never previously tested for HIV, and they showed a greater willingness to distribute HIVST kits to their sexual partners (P=.002) than the IPs. After controlling for age, education, and income, the alters had a greater proportion of MSM who had never tested for HIV before (adjusted odds ratio [aOR] 1.29, 95% CI 1.00-1.68), were more willing to distribute the HIVST application link (aOR 1.71, 95% CI 1.21-2.40), had a lower number of sexual partners (aOR 0.71, 95% CI 0.57-0.90), and were less likely to search for sexual partners on the web (aOR 0.78, 95% CI 0.60-1.02) than IPs. In comparison, the rates of reactive HIVST results, conducting HIV confirmatory tests, HIV seropositivity, and initiation of HIV antiretroviral therapy were similar for IPs and alters. Conclusions The ISDHK model of distributing HIVST application links among the MSM population via social media is feasible. The ISDHK model should be used to supplement the DSDHK model to enable a greater proportion of the MSM population to know their HIV infection status.

Background The use of mobile health (mHealth), including smartphone apps, can improve the HIV prevention cascade for key populations such as men who have sex with men (MSM). In Malaysia, where stigma and discrimination toward MSM are high, the mHealth platform has the potential to open new frontiers for HIV prevention efforts. However, little guidance is available to inform researchers about privacy and confidentiality concerns unique to the development and implementation of app-based HIV prevention programs. Objective Given the lack of empirical data in this area, we aim to understand the privacy and confidentiality concerns associated with participation in a hypothetical app-based research study for HIV prevention efforts. Methods A cross-sectional, web-based survey was conducted between June and July 2020 among 355 Malaysian MSM. The survey included demographic and sexual health questions and a series of short videos describing a hypothetical app-based HIV prevention program, followed by questions related to privacy and confidentiality concerns in each step of the app-based program (ie, recruitment, clinical interaction, risk assessment, and weekly reminder). Multivariable logistic regression models were used to identify the correlates of willingness to use such an app-based program. Results Most of the participants (266/355, 74.9%) indicated their willingness to participate in a hypothetical mHealth app–based HIV prevention program. Participants expressed concerns about privacy, confidentiality, data security, and risks and benefits of participating in all stages of the app-based HIV research process. Multivariate analyses indicated that participants who had a higher degree of perceived participation benefits (adjusted odds ratio [aOR] 1.873; 95% CI 1.274-2.755; P=.001) were more willing to participate. In contrast, participants who had increased concerns about app-based clinical interaction and e-prescription (aOR 0.610; 95% CI 0.445-0.838; P=.002) and those who had a higher degree of perceived risks of participating (aOR 0.731; 95% CI 0.594-0.899; P=.003) were less willing to participate. Conclusions Overall, our results indicate that mHealth app–based HIV prevention programs are acceptable for future research on Malaysian MSM. The findings further highlighted the role of privacy and confidentiality, as well as the associated risks and benefits associated with participation in such a program. Given the ever-evolving nature of such technological platforms and the complex ethical–legal landscape, such platforms must be safe and secure to ensure widespread public trust and uptake.
