Afr J Prim Health Care Fam Med 2024; 16:e1-e12. [PMID: 38708735 PMCID: PMC11079388 DOI: 10.4102/phcfm.v16i1.4088] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2023] [Revised: 10/31/2023] [Accepted: 11/01/2023] [Indexed: 05/07/2024] Open
Abstract
BACKGROUND Targeted interventions for key populations remain critical for realisation of epidemic control for human immunodeficiency virus (HIV) infection because of the causal relationship between HIV infection in the general population and among key population groups. AIM To consolidate evidence on the fast-track interventions towards achieving HIV epidemic control among key populations. METHODS A rapid scoping review was conducted using the methodological framework by Arksey and O' Malley. The Population, Intervention, Context and Outcome (PICO) framework was used to identify relevant studies using key words with Boolean operators in electronic data bases, namely CINHAL, Web of Science, Psych Info and Sabinet. Studies were extracted using a modified data extraction tool, and results were presented narratively. RESULTS A total of 19 articles were included in this review. Most articles were primary studies (n = 17), while another involved the review of existing literature and policies (n = 2) and routinely collected data (n = 1). Most studies were conducted in the United States of America (n = 6), while another were conducted in China, Kenya, Botswana, South Africa and Mozambique. All studies revealed findings on tested interventions to achieve HIV epidemic control among key populations. CONCLUSION Effective interventions for HIV epidemic control were stand-alone behavioural preventive interventions, stand-alone biomedical preventive strategies and combination prevention approaches. Furthermore, the findings suggest that effective activities to achieve HIV epidemic control among key populations should be centred around prevention.Contribution: The findings of this study have policy and practice implications for high HIV burden settings such as South Africa in terms of interventions to facilitate realisation of the Joint United Nations Programme on HIV/AIDS (UNAIDS) 95-95-95 targets, thereby contributing to HIV epidemic control.

HIV Testing Strategies, Types of Tests, and Uptake by Men Who have Sex with Men and Transgender Women: A Systematic Review and Meta-analysis. AIDS Behav 2023; 27:678-707. [PMID: 35984608 DOI: 10.1007/s10461-022-03803-5] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 07/24/2022] [Indexed: 11/01/2022]
Abstract
This systematic review and meta-analysis investigated the effectiveness of strategies and types of tests on HIV testing uptake by men who have sex with men (MSM) and transgender women (TGW), and in reaching PLWH. Articles published up to July 2020 were identified from major electronic databases and grey literature. Data were extracted and assessed for risk of bias. Estimates were pooled using random-effect meta-analysis while heterogeneity was evaluated by Cochran's Q test and I2. This study is registered with PROSPERO (CRD42020192740). Of 6820 titles, 263 studies (n = 67,288 participants) were included. The testing strategies reported in most studies were community- (71.2%) and facility-based (28.8%). Highest uptake, with facility-based testing, occurred and reached more PLWH while with standard laboratory tests, it occurred with the highest HIV prevalence among MSM. However, urine test showed a highest rate of new HIV infection. Multiple test combinations had the highest uptake and reached more PLWH among TGW. Various testing strategies, considering barriers and regional differences, and different test types, need be considered, to increase uptake among MSM and TGW.

Abstract
This systematic review and meta-analysis aims to compare the effects of couple-based prevention interventions against individual-level interventions on HIV prevention in randomized controlled trials (RCTs), identify potential moderators, and assess study quality. Eleven RCTs were included, comprising 3933 couples in the intervention group and 7125 individuals in the individual control group, predominantly in heterosexual couples from the USA and Africa. Couple-based interventions had a more significant effect in promoting condom use and HIV testing. Education levels of high school or above, residence in low- and middle-income countries, and intervention design incorporating HIV counseling and testing were associated with higher odds of condom use. The quality assessment analysis identified methodological and theoretical heterogeneity factors. Evidence of couple-based HIV prevention RCTs among men who have sex with men, injecting drug users, sex workers, and transgender women warrant further investigation. Recommendations are made to improve the quality and replicability of future intervention studies.

Abstract
The use of multiple HIV prevention services has been found to decrease the risk of acquiring HIV when tailored to individuals at risk of HIV exposure, including transport workers. Therefore, we assessed the uptake of multiple HIV prevention services (≥2) and associated factors among transport workers in a city in Southwestern Uganda. This cross-sectional study comprised motorcycle taxi riders, motor vehicle and truck drivers, aged 18 to 55 years who were selected and responded to an interviewer-administered questionnaire, between November 2021 and February 2022. Data was analyzed using descriptive statistical and modified Poisson regression analyses. Out of 420 participants, 97.6% were male, with a median age of 28 years and the majority were aged <34 years (84.6%). Overall, less than half (45.3%) of the participants had used multiple (≥2) HIV prevention services within a one-year period. Many participants had used condoms (32.2%) followed by voluntary HIV counseling and testing (27.1%), and safe male circumcision (17.3%). Most participants who tested for HIV had ever used condoms (16.2%), followed by those who received safe male circumcision and had ever used condoms (15%), and those who tested for HIV and had started on antiretroviral therapy (ART) (9.1%). In the adjusted model, factors that were significantly associated with the use of multiple HIV prevention services included religion (aPR = 1.25, 95% CI = 1.05-1.49), the number of concurrent sex partners (aPR = 1.33, 95% CI = 1.10-1.61), prior HIV testing and awareness of HIV serostatus (aPR = 0.55, 95% CI = 0.43-0.70), awareness of HIV prevention services (aPR = 2.49, 95% CI = 1.16-5.38), and financial payment to access HIV services (aPR = 2.27, 95% CI = 1.47-3.49). In conclusion, the uptake of multiple HIV prevention services among transport workers remains suboptimal. Additionally, individual behavioral factors influence the use of multiple HIV services compared with other factors. Therefore, differentiated strategies are needed to increase the utilization of HIV prevention services among transport workers.

BMC Infect Dis 2022; 22:679. [PMID: 35941562 PMCID: PMC9361597 DOI: 10.1186/s12879-022-07649-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2021] [Accepted: 07/25/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Interventions aimed at reducing risky sexual behavior are considered an important strategy for averting Human Immunodeficiency Virus (HIV) infection among youth (15-24 years) who continue to be at risk of the disease. Enhancing intervention success requires a comprehensive understanding of the barriers and facilitators to interventions targeting youth. However, there is lack of a systematic review of both quantitative and qualitative studies to comprehensively identify and synthesize barriers and facilitators to HIV prevention interventions for reducing risky sexual behavior among youth worldwide. This review aimed to identify and synthesize barriers and facilitators to HIV prevention interventions for reducing risky sexual behavior among youth globally based on original peer-reviewed studies published in the last decade. METHODS The Joanna Briggs Institute approach for mixed methods systematic reviews and Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines were used to guide this review. Nine electronic databases, Joint United Nations Programme on HIV/AIDS and World Health Organization websites, and reference lists of included studies and systematic reviews on barriers and facilitators to HIV prevention interventions for reducing risky sexual behavior among youth were searched for eligible articles. Studies that met the inclusion criteria underwent quality appraisal and data extraction. Findings were analyzed using thematic synthesis and underpinned by Nilsen, 2015's Determinant Framework. RESULTS Overall 13 studies comprising of eight qualitative studies, four quantitative studies and one mixed methods study were included in the review. Several barriers and facilitators across the five Determinant Framework domains were identified. Most of the barriers fell under the characteristics of the context domain (e.g., gender-biased norms). The next important group of barriers emerged within the characteristics of the end users domain (e.g., fear of relationship breakdown). In terms of facilitators, the majority fell under the characteristics of the strategy of facilitating implementation domain (e.g., implementation of intervention with fidelity) and characteristics of the end users domain (e.g., fear of pregnancy or sexually transmitted infections). The next common set of facilitators appeared within the characteristics of the context domain (e.g., family support). CONCLUSION This review identified several multi-level barriers and facilitators to HIV prevention interventions for reducing risky sexual behavior among youth. Multi-level and combination approaches are needed to address these factors and enhance intervention success.

Abstract
BACKGROUND Numerous cost-effectiveness analyses have indicated good value for money from a wide array of interventions for treatment and prevention of HIV/AIDS. There is limited evidence, however, regarding how cost-effectiveness information contributes to better decision-making around investment and action in the global HIV response. METHODS We review challenges for economic evaluation relevant to the global HIV response and consider how the practice of cost-effectiveness analysis could integrate approaches and insights from implementation science to enhance the impact and efficiency of HIV investments. RESULTS In light of signals that cost-effectiveness analyses may be vulnerable to systematic bias toward overly optimistic conclusions, we emphasize two priorities for advancing the field of economic evaluation in HIV/AIDS and more broadly in global health: (1) systematic reevaluation of the cost-effectiveness literature with reference to ex-post empirical evidence on costs and effects in real-world programs and (2) development and adoption of good-practice guidelines for incorporating implementation and delivery aspects into economic evaluations. Toward the latter aim, we propose an integrative approach that focuses on comparative evaluation of strategies, which specify both technologies/interventions as well as the delivery platforms, complementary interventions, and actions needed to increase coverage, quality, and uptake of those technologies/interventions. Specific recommendations draw on several existing implementation science models that provide systematic frameworks for understanding implementation barriers and enablers, designing and choosing specific implementation and policy actions, and evaluating outcomes. DISCUSSION These preliminary steps aimed at bridging the divide between economic evaluation and implementation science can help to advance the practice of economic evaluation toward a science of comparative strategy evaluation.

Abstract
The objective of this study was to examine direct and indirect relationships among peer norms, self-efficacy, and condom use among Chinese men who have sex with men (MSM). A longitudinal study determined the effectiveness of a condom use video promotion among Chinese MSM in 2015. In this analysis, 804 Chinese MSM were recruited at baseline and then followed at 3 weeks and 3 months after the intervention. Parallel process latent growth curve modeling (LGM) with multiple indicators and bootstrapping was conducted using Mplus 7.4. The LGM model fit indexes were good with RMSEA = 0.046, 90% CI (0.044, 0.048), CFI = 0.956, TLI = 0.955. Our results showed that the initial measure of peer norms affected the initial measure of condom use indirectly through the initial measure of self-efficacy (αβ = 0.414, 95% CI 0.260-0.759). The rate of change in peer norms over time also significantly affected the rate of change in condom use through the rate of change in self-efficacy (αβ = 0.101, 95% CI 0.014-0.262). Self-efficacy mediated the association between peer norms and condom use, indicating a strong potential of causal relationship between peer norms and self-efficacy among Chinese MSM.

Do combination HIV prevention programmes result in increased empowerment, inclusion and agency to demand equal rights for marginalised populations in low-income and middle-income countries? A systematic review. BMJ Glob Health 2019; 4:e001560. [PMID: 31673432 PMCID: PMC6797339 DOI: 10.1136/bmjgh-2019-001560] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2019] [Revised: 07/30/2019] [Accepted: 09/11/2019] [Indexed: 12/23/2022] Open
Abstract
Introduction This systematic review aims to determine if combination HIV prevention programmes include outcome measures for empowerment, inclusion and agency to demand equal rights and measure the relationship between empowerment and HIV prevention outcomes. Methods An electronic literature search of PubMed, POPLINE, Index Medicus and Google Scholar was conducted between August and October 2018. We included studies that evaluated combination prevention programmes that had all three types of intervention components and that specifically serve members of populations disproportionately affected by HIV published from 2008 to 2018. The selected studies were screened for inclusion, and relevant data abstracted, assessed for bias and synthesised. Results This review included a total of 15 studies. Findings indicate that combination HIV prevention programmes for marginalised populations have delivered a variety of theory-based behavioural and structural interventions that support improvements in empowerment, inclusion and agency. However, empowerment, inclusion and least of all agency are not measured consistently or in a standardised way. In addition, analysis of their relationships with HIV prevention outcomes is rare. Out of our 15 included studies, only two measured a relationship between an empowerment, inclusion or agency outcome and an HIV prevention outcome. Conclusion These findings suggest that policy-makers, programme planners and researchers might need to consider the intermediate steps on the pathway to increased condom use and HIV testing so as to explain the ‘how’ of their achievements and inform future investments in HIV prevention. This will support replication and expansion of programmes and ensure sustainability of the programmes. PROSPERO registration number CRD42018106909

A systematic review and meta-analysis of evidence (2007-2018). PLoS One 2019; 14:e0219826.

Abstract
Background Reaching the Joint United Nations Programme on HIV/AIDS (UNAIDS) 90-90-90 targets to end the HIV epidemic relies on effective interventions that engage untested HIV+ individuals and retain them in care. Evidence on community-based interventions through the lens of the targets has not yet been synthesized, reflecting a knowledge gap. We conducted a systematic review and meta-analysis to shed light on successful community-based interventions that have been effective in contributing, directly or indirectly, towards the UNAIDS 90-90-90 targets: knowledge of HIV status, linkage to care/on treatment, and viral suppression. Linkage to care was also included in this review due to the limitations of studies. Methods We conducted a systematic review and meta-analysis of the period 2007–2018. Eleven databases were searched to identify community-based interventions designed to improve knowledge of HIV status (in particular HIV testing), linkage to care/on treatment, and/or viral suppression. Eligible studies were classified by intervention, population, country income level, outcomes and success. Success was defined as interventions demonstrating statistical significance between intervention and control group or that reached any target by proportion; 90% testing, 81% linked to care/on treatment and 73% viral suppression. Results Of 82 eligible studies, 51.2% (42/82) reported on HIV testing (first 90), 20.7% (17/82) on linkage to care/ on treatment (second 90), and 45.1% (37/82) on viral suppression (third 90). In all, 67.1% (55/82) of studies reported success; 21 studies on the first 90, 9 towards linkage to care/on treatment, and 25 towards the third. By strategies, 36.6% deployed community workers/peers, 22% used combined test and treat strategies, 12.2% used educational methods, 8.5% used mobile testing, 7.3% used campaigns and 13.4% used technology. For HIV testing/linkage, combined test/treat interventions were often used, for viral suppression, educational interventions and technologies were commonly deployed. Our pooled analysis suggested that deployment of community health care workers/peer workers significantly improved viral suppression (pooled OR: 1.40 95% CI 1.06–1.86). Of the studies published after 2014, 50.0% reported metrics aligned with UNAIDS targets. Conclusions Data on linkage to care/on treatment (second target) remained weak, because many studies reported successes on the first and third targets. Stratification by targets and country income levels is informative and guides adaptation of successful interventions in comparable settings. Consistent reporting of clear metrics aligned with UNAIDS targets will aid in synergy of study data with programmatic data that will help reportage. Exploration of innovative interventions, for engagement and linkage and deployment of community/ peer workers is strongly encouraged.

Abstract
The goal to effectively prevent new HIV infections among gay, bisexual, and other men who have sex with men (MSM) is more challenging now than ever before. Despite declines in the late 1990s and early 2000s, HIV incidence among MSM is now increasing in many low- and high-income settings including the US, with young, adolescent, and racial/ethnic minority MSM being among those at highest risk. Potentiating HIV risks across all settings are individual-, network-, and structural-level factors such as stigma and lack of access to pre-exposure prophylaxis (PrEP) and antiretroviral treatment as prevention. To make a sustained impact on the epidemic, a concerted effort must integrate all evidence-based interventions that will most proximally decrease HIV acquisition and transmission risks, together with structural interventions that will support improved coverage and retention in care. Universal HIV treatment, increased access to HIV testing, and daily oral PrEP have emerged as integral to the prevention of HIV transmission, and such efforts should be immediately expanded for MSM and other populations disproportionately affected by HIV. Respect for human rights and efforts to combat stigma and improve access to prevention services are needed to change the trajectory of the HIV pandemic among MSM.

[PMID: 30886716 PMCID: PMC6413419 DOI: 10.1177/2050312119836030] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2018] [Accepted: 01/04/2019] [Indexed: 12/21/2022] Open
Abstract
Objectives Florida ranks highest in the United States among newly diagnosed HIV infections. This ranking reflects the need for investigation of healthcare providers' knowledge, readiness, prescribing behaviors, and perceived barriers to routine HIV testing and pre-exposure prophylaxis. Methods We adapted national questionnaires with questions co-developed with Florida Department of Health to form a 25-item instrument. Questionnaires were distributed to the population of eligible healthcare providers in DeLand, Florida. Results Results from an approximate 20% response rate that encompasses 12 providers demonstrate baseline findings to inform future studies. For example, 75% of respondents were aware of FL Administrative Code 64D-3.042 that pregnant women should receive HIV testing during first and third trimesters. However, 50% of respondents rarely or never offer tests to pregnant women according to practice guidelines. About 75% of respondents strongly agree or agree with willingness to prescribe pre-exposure prophylaxis to high-risk patients, yet 8.3% always or very often prescribe pre-exposure prophylaxis. Conclusions Results convey the importance of and need for greater collaboration between providers and the Florida Department of Health to enhance providers' knowledge, readiness, and, ultimately, behaviors regarding routine HIV testing and pre-exposure prophylaxis prescription.

Stigma and outness about sexual behaviors among cisgender men who have sex with men and transgender women in Eswatini: a latent class analysis. BMC Infect Dis 2019; 19:211. [PMID: 30832602 PMCID: PMC6399954 DOI: 10.1186/s12879-019-3711-2] [Citation(s) in RCA: 25] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2017] [Accepted: 01/10/2019] [Indexed: 11/12/2022] Open
Abstract
Background Men who have sex with men (MSM) and transgender women in Sub-Saharan Africa are subjected to high levels of sexual behavior-related stigma, which may affect mental health and sexual risk behaviors. MSM and transgender women who are open about, or have disclosed their sexual behaviors appear to be most affected by stigma. Characterizing the mechanism of action of stigma in potentiating HIV-risks among these key populations is important to support the development of interventions. Methods In this study, a total of 532 individuals were recruited across Eswatini (Swaziland) through chain-referral-sampling from October – December 2014, including 419 cisgender MSM and 109 transgender women. Participants were surveyed about demographics, stigma, outness of same-sex practices to family members and healthcare workers, and mental and sexual health. This study used latent class analysis (LCA) to determine latent constructs of stigma/outness, and used multinomial logistic regression to determine associations with underlying constructs and sexual risk behaviors. Results Three latent classes emerged: 1) Those who reported low probabilities of stigma (55%; 276/502); 2) Those who reported high probabilities of stigma including physical violence and fear/avoidance of healthcare, and were not “out” (11%; 54/502); and 3) Those who reported high probabilities of stigma including verbal harassment and stigma from family and friends, and were “out” (34%; 172/502). Relative to the “low stigma” class, participants from an urban area (adjusted odds ratio [AOR] = 2.78, 95% Confidence Interval [CI] = 1.53–5.07) and who engaged in condomless anal sex (AOR = 1.85, 95% CI = 1.17–2.91) were more likely to belong to the “high stigma, ‘out’” class. In contrast, those who had a concurrent male or female partner were more likely to belong to the “high stigma, not ‘out’” class AOR = 2.73, 95% CI = 1.05–7.07). Depression was associated with membership in both high-stigma classes (AOR = 3.14, 95% CI = 1.50–6.55 “not out”, AOR = 2.42, 95% CI = 1.51–3.87 “out”). Conclusions Sexual behavior stigma at a community level is associated with individual-level risk behaviors among MSM and transgender women, and these associations vary by level of outness about sexual practices. Achieving sufficient coverage of evidence-based stigma interventions may be key to realizing the potential impact of HIV prevention and treatment interventions for MSM and transgender women in Eswatini.

Abstract
This paper estimates population-based prevalence of HIV, syphilis, HSV-2 and factors influencing HIV infection using a national sample of 1914 female sex workers (FSWs) in 7 regions in Tanzania. Additionally, HIV incidence was estimated by comparing biological HIV results with self-reported HIV status. The average HIV prevalence among FSWs in all 7 regions was 28%, ranging from 14% in Tabora to 38% in Shinyanga. HIV incidence was found to be 13 per 100 person-years. Syphilis prevalence was 8% with significantly higher burden found in Iringa (11%), Mbeya (13%), and Shinyanga (12%). Nearly 60% of the study population was infected with HSV-2. The high HIV prevalence and incidence coupled with suboptimal condom use indicate an urgent need to roll out the "Treat-All" approach and provide antiretroviral therapy to FSWs living with HIV regardless of their CD4 count. In addition, antiretroviral-based prevention technologies such as oral pre-exposure prophylaxis and microbicides should be piloted and evaluated.

Abstract
This study aims to describe the transgender women and men who have sex with men (MSM) missed through venue-based sampling and illustrate how data on venues can be used to prioritize service delivery. Respondent-driven sampling (RDS) and time-location sampling (TLS) were used concurrently in 2010 for behavioral surveillance among MSM and transgender women in Guatemala City. RDS recruits who did not frequent venues (n = 106) were compared to TLS recruits (n = 609). TLS participants recruited at different types of venues were compared. RDS recruits who did not frequent venues were less educated, less likely to identify as gay, more likely to have concurrent partners and female sexual partners. Participants recruited at NGOs, saunas, hotels, streets and parks had more partners, were more likely to receive money for sex or have concurrent partners. Prevention programs for MSM and transgender women should characterize social venues and people that frequent them and improve service coverage through venues and social networks.

Abstract
BACKGROUND Substance use is common among men who have sex with men (MSM) worldwide, and epidemiologic data suggest that alcohol/substance-using MSM are at greater risk for HIV. However, there are scarce data on substance abuse treatment programs (SATPs) for substance-using MSM. OBJECTIVES We examined proportions of substance use as well as SATP availability and use. We used multivariable regression models, controlling for potential confounders, to examine behavioral and demographic correlates of SATP availability and use. METHODS This is a cross-sectional study of a multi-region, online sample of substance-using MSM. RESULTS In this sample, 75% were substance-using MSM of whom 36% reported at-least-weekly use. Substance use was most prevalent among respondents from Eastern Europe/Central Asia (86%) and Latin America (79%). Among substance-using MSM, 96% and 33% reported alcohol intoxication and other substance use, respectively; 11% reported having high SATP availability; and 5% reported using SATPs. Controlling for global region of origin and age, high SATP availability was associated with high access to HIV risk-reduction education (aOR = 3.19; CI = 1.48-6.89), mental health services (aOR = 2.53; CI = 1.32-4.83), and medical care (aOR = 2.32; CI = 1.12-4.80); less than college-level education (aOR = 0.32; CI = 0.18-0.54); and higher comfort levels with providers (aOR = 1.75; CI = 1.30-2.37). Controlling for substance use frequency and personal income additionally, using SATPs was associated with higher levels of connection to the gay community (aOR = 2.76; CI = 1.22-6.22). CONCLUSION In this global sample of MSM, we found high alcohol intoxication and other substance use proportions. Few substance-using MSM report SATP availability, highlighting the need to develop novel substance use programs outside traditional treatment settings.

Abstract
El Salvador was one of three countries to receive funding from the Global Fund to Fight AIDS, Tuberculosis and Malaria to conduct a combination HIV prevention intervention among transwomen (TW), men who have sex with men (MSM), and commercial sex workers (CSW). Program evaluation revealed that prevention activities reached only 50% of the target population. The purpose of this study is to examine the barriers that Salvadoran educators faced in implementing the peer education as designed and adaptations made as a result. Between March and June 2015, 18 in-depth interviews with educators were conducted. Violence was reported as the biggest barrier to intervention implementation. Other barriers differed by subpopulation. The level of violence and discrimination calls into question the feasibility and appropriateness of peer-led interventions in the Salvadoran context and demonstrates the importance of implementation research when translating HIV prevention interventions developed in high-income countries to low- and middle-income countries.

Abstract
Gay, bisexual, and other men who have sex with men (MSM) have adapted their sexual practices over the course of the HIV/AIDS epidemic based on available data and knowledge about HIV. This study sought to identify and compare patterns in condom use among gay, bisexual, and other MSM who were tested for HIV at a community-based testing site in Montreal, Canada. Results showed that while study participants use condoms to a certain extent with HIV-positive partners and partners of unknown HIV status, they also make use of various other strategies such as adjusting to a partner's presumed or known HIV status and viral load, avoiding certain types of partners, taking PEP, and getting tested for HIV. These findings suggest that MSM who use condoms less systematically are not necessarily taking fewer precautions but may instead be combining or replacing condom use with other approaches to risk reduction.

Abstract
Four HIV rapid tests were subjected to field validation in Panama and compared to an enzyme-linked immunosorbent assay/Multispot-based testing algorithm. The sensitivities of Determine, Uni-Gold, SD Bioline, and INSTI were 99.8%. The specificities of Determine, SD-Bioline, and Uni-Gold were 100%, and the specificity of INSTI was 99.8%. On the basis of these data, we determined that these rapid tests can be used in an appropriate algorithm to diagnose HIV infection and are suitable for use in testing and counseling settings in Panama.
