ABSTRACT
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.

BACKGROUND: This study aimed to determine the prevalence and factors associated with susceptibility to hepatitis B virus (HBV) among cisgender men who have sex with men (MSM) on HIV pre-exposure prophylaxis (PrEP) in Northeastern Brazil. METHODS: This was a cross-sectional, analytical study conducted between September 2021 and June 2023. Participants underwent structured interviews to collect sociodemographic and clinical information, including hepatitis B vaccination history, HIV PrEP use and sexual health history. Blood samples were collected for hepatitis B serologic testing: HBV surface antigen (HBsAg), HBV surface antibody (anti-HBs), total and IgM HBV core antibody (anti-HBc). HBV susceptibility was defined as nonreactive results for all these serological markers. RESULTS: A total of 287 participants were enrolled into the study. The median age of the individuals was 31 years (interquartile range: 27; 36). HBV susceptibility was found in 58 out 286 individuals (20.3%; 95% CI: 15.9-25.2). Seventy-six percent of the participants reported completing the three-dose hepatitis B vaccine schedule. Susceptibility was significantly associated with a monthly income ≤ 5 minimum wages (PR: 2.02; 95% CI: 1.01-4.05), lack of complete hepatitis B vaccination schedule (PR: 4.52; 95% CI: 2.89-7.06), initiation of HIV PrEP (PR: 2.18; 95% CI: 1.21-3.94), duration of six months of HIV PrEP (PR: 2.16; 95% CI: 1.19-3.91), absence of tattoos (PR: 1.55; 95% CI: 1.00-2.40) and no history of sexually transmitted infections (PR: 1.65; 95% CI: 1.07-2.54). CONCLUSION: Our findings highlight the significant burden of HBV susceptibility among MSM on HIV PrEP in Northeastern Brazil. Socioeconomic factors, vaccination status, PrEP use and sexual health behaviors play critical roles in determining susceptibility to HBV. Integrating hepatitis B screening and vaccination into PrEP services is critical for identifying and addressing HBV susceptibility among MSM. Interventions aimed at increasing vaccination coverage and promoting safer sexual practices are essential for mitigating the burden of HBV infection in this population.

BackgroundSyphilis in blood donors (BD) has increased in many countries.AimWe aimed to describe trends in syphilis seroposivity in BD in France, to identify risk factors and assess if a non-treponemic test (NTT) could define BD having recovered from syphilis for more than 1â¯year.MethodsThe analysis covered the period 2007 to 2022 and 45,875,939 donations. Of the 474 BD syphilis-positive in 2022, 429 underwent additional investigations with an NTT. History of syphilis was obtained at the post-donation interview or based on serology results for repeat donors.ResultsUntil 2021, positivity rates remained stable (mean: 1.18/10,000 donations, range: 1.01-1.38). An increased rate was observed in 2022 (1.74/10,000; p = 0.02). Over the whole study period, prevalence was 2.2 times higher in male than in female BD (4.1 times higher in 2022). The proportion of males with an identified risk factor who have sex with men increased from 16.7% in 2007 to 64.9% in 2022. Based on NTT, 79 (18%) of the donors who were seropositive in 2022 were classified as having been infected in the previous year. History of syphilis was available for 30 of them. All had an infection within the previous 3 years. Among seven donors with a syphilis < 12 months before testing, one had an NTT titre ≥ 8, three a titre between 1 and 4, three were negative.ConclusionSyphilis seropositivity increased considerably in BDs in 2022, mostly in males, notably MSM. Available data did not allow appropriate evaluation of the NTT to distinguish recent from past infection.

BACKGROUND: DiversiPrEP is a culturally-tailored PrEP program for LMSM offered in South Florida. DiversiPrEP navigates LMSM through their PrEP journey, including education, deciding if PrEP is relevant for them, payment, and accessing/maintaining PrEP use. DiversiPrEP includes five ERIC strategies (Increase Demand, Promote Adaptability, Alter Client Fees, Intervene with Clients to Enhance Uptake and Adherence, and Tailor Strategies). DESCRIPTION: Photovoice was used to conduct five two-part focus groups with LMSM (n = 12) and Non-LMSM (n = 12). In the first session, trainers provided guidance on selecting and contextualizing photos to generate CFIR themes. Then, participants captured photos that embodied their lived experiences accessing PrEP. In the second session, using SHOWeD, participants discussed photos, identifiedhow photos relate to culturally relevant issues. Triangulation approaches compared/contrasted themes between LMSM and Non-LMSM. RESULTS: Five central themes emerged around barriers and facilitators to PrEP services: 1) the need for normalizing PrEP messages within the MSM community, 2) the need for normalizing PrEP messages outside the MSM community, 3) the need for expanding PrEP knowledge, 4) different motivations for using PrEP, and 5) the presence of structural barriers that limit PrEP access. This study compared similarities and differences of barriers and facilitators to PrEP use between Latino/a and non-Latino/a MSM. Similarities included the built environment (outer setting) as a barrier, the need for normalizing PrEP messaging within and outside of the MSM community, and the need to expand PrEP knowledge. Differences between Latino/a and non-Latino/a MSM were found in assessing the motivation and personal drivers (inner setting) for initiating PrEP associated with how participants viewed their responsibilities to self or others. CONCLUSIONS: Photovoice with focus groups identified CFIR constructs that can guide the large-scale implementation of a client-centered PrEP service model with telehealth for both Latino/a and non-Latino/a MSM. Implementing client-centered accessible PrEP programs is an essential step to promoting sexual-health equity.

OBJECTIF: Présenter un guide à l'intention des professionnels des soins primaires sur le dépistage approprié des infections transmissibles sexuellement (ITS) chez des patients qui s'identifient comme des hommes ayant des rapports sexuels avec des hommes (HSH). SOURCES DE L'INFORMATION: Les lignes directrices canadiennes sur le dépistage des ITS et des infections entériques et par des protozoaires; les lignes directrices ontariennes sur le dépistage du VIH et du mpox; et les lignes directrices américaines sur le dépistage des ITS. MESSAGE PRINCIPAL: Dans toutes les régions du Canada, les taux des infections bactériennes, entériques, par protozoaires et systémiques, y compris le VIH et la mpox, qui sont transmissibles sexuellement, ont augmenté de manière constante chez les HSH cisgenres et transgenres. Même si elles présentent souvent des tableaux cliniques semblables, ces infections ont diverses périodes d'incubation et requièrent des méthodes de dépistage différentes, et leur présence doit être effectivement exclue afin d'orienter le diagnostic et le traitement chez des patients qui s'identifient comme des HSH et ont des symptômes de divers problèmes de santé. Par ailleurs, les renseignements et les recommandations cliniques se trouvent souvent dans de multiples lignes directrices plutôt que dans une seule source, ce qui complique encore davantage ces rencontres cliniques. Ce document fournit une consolidation des données probantes et des recommandations sur le dépistage des ITS chez les HSH. CONCLUSION: Les approches de dépistage des ITS devraient être rigoureuses, et fondées sur les facteurs de risque signalés par le patient et sur la présentation clinique. Lorsqu'un risque d'ITS est cerné, mais que les résultats des analyses en laboratoire sont négatifs, il faudrait aussi expliquer aux HSH les recommandations entourant la répétition des tests, de même que les services de prévention du VIH, comme la prophylaxie préexposition.

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.

BACKGROUND: In Brazil, ~35% of people living with HIV (PLHIV) have poor adherence to antiretroviral therapy (ART). HIV-related stigma is associated with worst continuum of care outcomes, however evidence from Brazil is scarce. We explored pathways between HIV-related stigma dimensions and ART adherence among Brazilian cisgender gay, bisexual and other men who have sex with men (MSM) living with HIV. METHODS: A sample of MSM ≥18 years was recruited online between February/March 2020 through advertisements on Hornet, a location-based dating app. Validated scales were used to assess ART adherence and HIV-related stigma. Indirect and direct pathways between HIV-related stigma dimensions and ART adherence were estimated using structural equation models while considering socio-demographic and substance use related variables. Models were estimated using mean- and variance-adjusted weighted least squares, and goodness of fit indices were calculated. FINDINGS: Among 1,719 MSM living with HIV who reported starting ART, 70% were adherent. There was evidence of indirect effects of concerns about public attitudes (standardized coefficient (SC) = -0.095, 95% confidence interval (95%CI) = -0.172 - -0.017) and personalized HIV-stigma (SC = -0.022, 95%CI = -0.043 - -0.001) on ART adherence mediated through negative self-image. Personalized HIV stigma and concerns about public attitudes were both positively associated with negative self-image (SC = 0.129, 95%CI = 0.066-0.193; SC = 0.549, 95%CI = 0.494-0.603), and concerns about public attitudes was associated with HIV disclosure concerns (SC = 0.522, 95%CI = 0.463-0.581). However, the direct paths from personalized HIV stigma and concerns about public attitudes to ART adherence were not significant. INTERPRETATION: Our research underscores the critical need for multifaceted interventions to eliminate HIV-related stigma at both individual and societal levels. At the individual level, psychotherapeutic interventions to improve self-image might helpful. Additionally, public policy should aim to dismantle structural stigma with awareness campaigns on various media channels, integration of anti-stigma curriculum into schools, and training for professionals.

The HIV test is an important strategy for HIV prevention and treatment, starting from screening individuals who are unaware of being infected with HIV and requiring antiretroviral therapy. Information about sexual behavior factors related to HIV testing initiatives among MSM in Indonesia is still limited. Previous studies only showed the correlation of various sexual behavior variables with the decision whether to obtain an HIV test or not; but did not learn whether the HIV testing was obtained due to personal initiative or invited by others. This research can be used as a reference for developing an HIV testing program based on sexual behavior variables. This research aims to study the sexual behavior factors related to the personal initiative on taking the HIV test among men who have sex with men (MSM). We used cross-sectional study among 300 MSM who had an HIV test. This research found that homosexual orientation was negative factor related to the personal initiative for obtaining an HIV test. Sexual behavior among MSM is correlated with the personal initiative to take HIV testing. Further investigation should emphasize among homosexuals because they do not have the initiative to take an HIV test.
Le test du VIH est une stratégie importante pour la prévention et le traitement du VIH, qui commence par le dépistage des personnes qui ignorent qu'elles sont infectées par le VIH et qui nécessitent un traitement antirétroviral. Les informations sur les facteurs de comportement sexuel liés aux initiatives de dépistage du VIH parmi les HSH en Indonésie sont encore limitées. Des études antérieures ont uniquement montré la corrélation entre diverses variables du comportement sexuel et la décision d'obtenir ou non un test de dépistage du VIH; mais n'a pas appris si le test du VIH avait été obtenu grâce à une initiative personnelle ou sur invitation d'autres personnes. Cette recherche peut servir de référence pour développer un programme de dépistage du VIH basé sur des variables de comportement sexuel. Cette recherche vise à étudier les facteurs de comportement sexuel liés à l'initiative personnelle de faire le test du VIH chez les hommes ayant des rapports sexuels avec des hommes (HSH). Nous avons utilisé une étude transversale auprès de 300 HSH ayant subi un test de dépistage du VIH. Cette recherche a révélé que l'orientation homosexuelle était un facteur négatif lié à l'initiative personnelle d'obtenir un test de dépistage du VIH. Le comportement sexuel des HSH est corrélé à l'initiative personnelle de se soumettre au test du VIH. Une enquête plus approfondie devrait être menée auprès des homosexuels car ils n'ont pas l'initiative de faire un test de dépistage du VIH.

Nitrite inhalants (poppers) are associated with HIV transmission and commonly used among young men who have sex with men (YMSM), a group at increased risk for HIV. Significant research gaps exist in understanding the context in which YMSM use poppers. Qualitative interviews were conducted with 15 YMSM (22-31 years) with HIV to better understand the context in which poppers are used and their impacts on HIV care outcomes, such as care retention and antiretroviral adherence. The Social Ecological Model was applied to understand intrapersonal, interpersonal, community, and system level influences on popper use. Factors influencing popper use included: ubiquity of popper use in sexual settings, introduction to poppers by casual sexual partners, patient-HIV provider communication surrounding poppers, neighborhood, substance use and HIV care systems, and the legal status of poppers. Implications for clinical care, public health, policy, and future research are discussed.

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.

BACKGROUND: The ongoing multi-country mpox outbreak in previously unaffected countries is primarily affecting sexual networks of men who have sex with men. Evidence is needed on the effectiveness of recommended preventive interventions. To inform WHO guidelines, a systematic review and qualitative evidence synthesis were conducted on mpox preventive behavioural interventions to reduce: (i) sexual acquisition; (ii) onward sexual transmission from confirmed/probable cases; and (iii) utility of asymptomatic testing. METHODS: Medline, EMBASE, PubMed, Cochrane and WHO trial databases, grey literature and conferences were searched for English-language primary research published since 1 January 2022. A reviewer team performed screening, data extraction and bias assessment. A qualitative thematic synthesis explored views and experiences of engagement in prevention in individuals at increased risk. RESULTS: There were 16 studies: 1 on contact-tracing, 2 on sexual behaviour, and 13 on asymptomatic testing. Although MPXV was detected in varying proportions of samples (0.17%-6.5%), the testing studies provide insufficient evidence to fully evaluate this strategy. For the qualitative evidence synthesis, four studies evaluated the experiences of most affected communities. Preferences about preventive interventions were shaped by: mpox information; the diversity of sexual practices; accessibility and quality of mpox testing and care; and perceived cost to wellbeing. CONCLUSIONS: Evidence on the effectiveness of interventions to prevent the sexual transmission of mpox remains scarce. Limited qualitative evidence on values and preferences provides insight into factors influencing intervention acceptability. Given global and local inequities in access to vaccines and treatment, further research is needed to establish the effectiveness of additional interventions.

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.

BACKGROUND: Gay, bisexual, and other men who have sex with men (GBMSM) represent a high-risk group for HIV transmission in Romania, yet they possess few resources for prevention. Despite having no formal access to pre-exposure prophylaxis (PrEP) through the health system, GBMSM in Romania demonstrate a high need for and interest in this medication. In anticipation of a national rollout of PrEP, this study tests the efficacy of a novel strategy, Prepare Romania, that combines two evidence-based PrEP promotion interventions for GBMSM living in Romania. METHODS: This study uses a randomized controlled trial design to examine whether GBMSM living in Romania receiving Prepare Romania, a culturally adapted counseling and mobile health intervention (expected n = 60), demonstrate greater PrEP adherence and persistence than those assigned to a PrEP education control arm (expected n = 60). Participants from two main cities in Romania are prescribed PrEP and followed-up at 3 and 6 months post-randomization. PrEP adherence data are obtained through weekly self-report surveys and dried blood spot testing at follow-up visits. Potential mediators (e.g., PrEP use motivation) of intervention efficacy are also assessed. Furthermore, Prepare Romania's implementation (e.g., proportion of enrolled participants attending medical visits, intervention experience) will be examined through interviews with participants, study implementers, and healthcare officials. DISCUSSION: The knowledge gained from this study will be utilized for further refinement and scale-up of Prepare Romania for a future multi-city effectiveness trial. By studying the efficacy of tools to support PrEP adherence and persistence, this research has the potential to lay the groundwork for PrEP rollout in Romania and similar contexts. Trial registration This study was registered on ClinicalTrials.gov, identifier NCT05323123 , on March 25, 2022.

INTRODUCTION: Effective HIV prevention programme coverage is necessary to achieve Nigeria's goal of ending the epidemic by 2030. Recent evidence highlights gaps in service coverage and utilization across the country. The Effective Programme Coverage framework is a Programme Science tool to optimize a programme's population-level impact by examining gaps in programme coverage using data generated through programme-embedded research and learning. We apply the framework using Integrated Biological and Behavioural Surveillance Survey (IBBSS) data from Nigeria to examine coverage of four prevention interventions-condoms, HIV testing, and needle and syringe programmes (NSP)-among four key population groups-female sex workers (FSW), men who have sex with men (MSM), people who inject drugs (PWID) and transgender people. METHODS: Data from Nigeria's 2020 IBBSS, implemented in 12 states, were analysed to examine HIV prevention programme coverage among key populations. For each key population group and prevention intervention of interest, weighted IBBSS data were used to retrospectively generate coverage cascades that identify and quantify coverage gaps. Required coverage targets were informed by targets articulated in Nigeria's National HIV/AIDS Strategic Framework or, in their absence, by guidelines from policy normative bodies. Availability-, outreach- and utilization coverage proxy indicators were defined using variables from IBBSS data collection tools. Sankey diagrams are presented to visualize pathways followed by participants between coverage cascade steps. RESULTS: Required coverage targets were missed for HIV testing and NSP among all key population groups. Condom availability coverage surpassed required coverage targets among FSW and MSM, while utilization coverage only among FSW exceeded the 90% required coverage target. Outreach coverage was low for all key population groups, falling below all required coverage targets. CONCLUSIONS: Our findings identify critical gaps in HIV prevention programme coverage for key populations in Nigeria and demonstrate non-linear movement across coverage cascades, signalling the need for innovative solutions to optimize coverage of prevention services. Programme-embedded research is required to better understand how key population groups in Nigeria access and use different HIV prevention services so that programmes, policies and resource allocation decisions can be optimized to achieve effective programme coverage and population-level impact.

INTRODUCTION: Chemsex, the use of psychotropic drugs before or during sexual intercourse, is associated with various HIV risk factors, including condomless sex and reduced adherence to pre-exposure prophylaxis or antiretroviral therapy (ART). In the Philippines, there are still limited studies exploring the associations between chemsex, HIV status and ART adherence. This study aims to compare recent and lifetime chemsex engagement in association with self-reported HIV status among Filipino men who have sex with men (MSM). We further explored the association between chemsex and ART adherence among people living with HIV engaged in chemsex. METHODS: A cross-sectional online survey of 479 Filipino MSM was conducted from 3 August to 1 December 2019. Demographic profiles, sexual behaviours, drug use, history of sexually transmitted infections (STIs), chemsex engagement and HIV status were collected and analysed. Bivariable and multivariable logistic regression were employed to assess the association between self-reported HIV status and chemsex engagement. RESULTS: Among the 479 respondents, Filipino MSM engaged in drug use and chemsex were generally older compared to those not engaged in drug use and chemsex (average age 31-33 vs. 29 years old; p<0.05). Methamphetamine was the most common drug for people who reported using drugs. An HIV-positive status was associated with recent chemsex engagement (aOR = 5.18, p<0.05) and a history of STIs (aOR = 2.09, p<0.05). The subgroup analysis showed that 79% (166/200) of persons living with HIV were adherent to ART. There was no significant association found between chemsex and ART adherence in the logistic regression analyses. CONCLUSIONS: Chemsex behaviour, particularly recent chemsex engagement, is significantly associated with self-reported HIV status. The emerging data on MSM engaged in chemsex require integration of a more person-centred, comprehensive and robust harm reduction programmes into the existing combination prevention strategies in the country. Health education for Filipino MSM engaged in chemsex should prioritize raising awareness about methamphetamine effects and overdose risks, alongside proper medical management.

INTRODUCTION: Measuring the coverage of HIV prevention services for key populations (KPs) has consistently been a challenge for national HIV programmes. The current frameworks and measurement methods lack emphasis on effective coverage, occur infrequently, lack timeliness and limit the participation of KPs. The Effective Programme Coverage framework, which utilizes a programme science approach, provides an opportunity to assess gaps in various coverage domains and explore the underlying reasons for these gaps, in order to develop targeted solutions. We have demonstrated the application of this framework in partnership with the KP community in Nairobi, Kenya, using an expanded Polling Booth Survey (ePBS) method. METHODS: Data were collected between April and May 2023 among female sex workers (FSWs) and men who have sex with men (MSM) using (a) PBS, (b) bio-behavioural survey and (c) focus group discussions. Data collection and analysis involved both KP community and non-community researchers. Descriptive analysis was performed, and proportions were used to assess the programme coverage gaps. The data were weighted to account for the sampling design and unequal selection probabilities. Thematic analysis was conducted on the qualitative data. RESULTS: The condom programme for FSW and MSM had low availability (60.2% and 50.9%), contact (68.8% and 65.9%) and utilization (52.1% and 43.9%) coverages. The pre-exposure prophylaxis (PrEP) programme had very low utilization coverage for FSW and MSM (4.4% and 2.8%), while antiretroviral therapy utilization coverage was higher (86.6% and 87.7%). Reasons for coverage gaps included a low peer educator-to-peer ratio, longer distance to the clinics, shortage of free condoms supplied by the government, experienced and anticipated side effects related to PrEP, and stigma and discrimination experienced in the facilities. CONCLUSIONS: The Effective Programme Coverage framework allows programmes to assess coverage gaps and develop solutions and a research agenda targeted at specific domains of coverage with large gaps. The ePBS method works well in collecting data to understand coverage gaps rapidly and allows for the engagement of the KP community.

BACKGROUND: Many European countries experienced outbreaks of mpox in 2022, and there was an mpox outbreak in 2023 in the Democratic Republic of Congo. There were many apparent differences between these outbreaks and previous outbreaks of mpox; the recent outbreaks were observed in men who have sex with men after sexual encounters at common events, whereas earlier outbreaks were observed in a wider population with no identifiable link to sexual contacts. These apparent differences meant that data from previous outbreaks could not reliably be used to parametrise infectious disease models during the 2022 and 2023 mpox outbreaks, and modelling efforts were hampered by uncertainty around key transmission and immunity parameters. METHODS: We developed a stochastic, discrete-time metapopulation model for mpox that allowed for sexual and non-sexual transmission and the implementation of non-pharmaceutical interventions, specifically contact tracing and pre- and post-exposure vaccinations. We calibrated the model to case data from Berlin and used Sobol sensitivity analysis to identify parameters that mpox transmission is especially sensitive to. We also briefly analysed the sensitivity of the effectiveness of non-pharmaceutical interventions to various efficacy parameters. RESULTS: We found that variance in the transmission probabilities due to both sexual and non-sexual transmission had a large effect on mpox transmission in the model, as did the level of immunity to mpox conferred by a previous smallpox vaccination. Furthermore, variance in the number of pre-exposure vaccinations offered was the dominant contributor to variance in mpox dynamics in men who have sex with men. If pre-exposure vaccinations were not available, both the accuracy and timeliness of contact tracing had a large impact on mpox transmission in the model. CONCLUSIONS: Our results are valuable for guiding epidemiological studies for parameter ascertainment and identifying key factors for success of non-pharmaceutical interventions.

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.

BACKGROUND: Since May 2022, mpox outbreaks have been occurring in non-mpox endemic areas, with the main population affected being men who have sex with men (MSM). Outbreak prevention and control depend not only on the effectiveness of vaccines but also on people's willingness to receive these vaccines. Currently, there is lack of synthesis on the overall rates and influence factors of MSMs' willingness to vaccinate against mpox. Therefore, we systematically reviewed studies that assessed the willingness of MSM to receive mpox vaccine. METHODS: Studies reporting mpox vaccination intentions among MSM were included by searching five databases (PubMed, Web of Science, EMBASE, CINAHL, and SCOPUS) from inception to May 12, 2024. The quality of the included literature was assessed using Joanna Briggs Institute's critical appraisal tool. The data analysis software is Stata17. The systematic review has been registered with Prospero (registration ID: CRD42023452357). RESULTS: Twenty cross-sectional studies were included in the review. Meta-analysis results showed that the pooled willingness rate of vaccinate against mpox was 77.0% (95% CI: 73-81%, I2 = 99.4%). According to subgroup analysis, study countries (P = 0.002), research sample size (P = 0.001), and whether participants were infected with HIV (P = 0.002) may be sources of heterogeneity. The results of the meta-analysis of influencing factors showed that more number of sexual partners (OR: 2.24, 95%CI: 1.86-2.69), pre-exposure prophylaxis use (OR: 6.04, 95%CI: 4.80-7.61), history of sexually transmitted infections (OR: 2.96, 95%CI: 2.33-3.76), confidence in the vaccine's effectiveness (OR: 2.79, 95%CI: 2.04-3.80) and safety (OR: 10.89, 95%CI: 5.22-22.72), fear of mpox infection (OR: 2.47, 95%CI: 2.11-2.89) and epidemics (OR: 2.87, 95%CI: 2.22-3.70), high mpox knowledge (OR: 2.35, 95%CI: 1.51-3.66), and the belief that people at high risk should be prioritized for vaccination (OR: 3.09, 95%CI: 1.40-6.84) were the facilitators of vaccine willingness. In addition, as a secondary outcome, meta-analysis results showed a pooled unwillingness rate of 16% (95% CI: 13-20%, I2 = 98.1%, 9 studies). CONCLUSION: Willingness to vaccinate mpox was high among MSM, but some participants still had negative attitudes towards vaccination. Therefore, the Ministry of Public Health should develop targeted and effective strategies against those influencing factors to prevent and manage mpox outbreaks.
