RÉSUMÉ

Stigmatisation processes constitute key barriers to effectively addressing the HIV pandemic. In this article, we provide a critical overview of this field's current state of the art, highlighting some key emerging issues that merit greater research attention in the future to ensure that contemporary research on stigmatisation and resistance processes continues to engage with changing social and political circumstances. We look at how resistance to stigma has developed in the context of HIV and highlight some of the most important programmatic strategies that have emerged over the history of the pandemic. We present the key concepts of 'moral panics' and 'necropolitics', and we articulate them in relation to new global phenomena that deepen the processes of stigmatisation. Moreover, we identify an agenda for investigation which merits greater attention in future research, intervention, and advocacy: 1) changing political environments, neoliberalism, growing political polarisation, and the rise of political extremism; 2) the rise of the information age, technological change, and social media; and 3) rebuilding civil society and governmental responses to stigma.

RÉSUMÉ

OBJECTIVE: To analyze HIV Post-Exposure Prophylaxis (PEP) prescription and return for follow-up appointments. METHODS: This was a descriptive cross-sectional study using data on people who sought PEP in emergency care units (UPAs) and specialized medical services in Salvador, BA, Brazil, between January-December/2018. RESULTS: Of the 1,525 people who sought PEP at UPAs, 1,273 (83.5%) met PEP eligibility criteria, while 252 (16.5%) did not; of the eligible group, 1,166 (91.6%) had antiretrovirals prescribed, while 107 (8.4%) eligible people did not; of the total number of people with PEP prescriptions, only 226 (19.4%) returned for the first follow-up appointment, 115 (9.9%) for the second, and 33 (2.8%) for the third in order to complete the protocol. CONCLUSION: We found a significant proportion of eligible users who did not have PEP prescribed at UPAs and a significant loss of return for specialized service follow-up appointments.

RÉSUMÉ

BACKGROUND: Primary Health Care (PHC) is essential for effective, efficient, and more equitable health systems for all people, including those living with HIV/AIDS. This study evaluated the impact of the exposure to one of the largest community-based PHC programs in the world, the Brazilian Family Health Strategy (FHS), on AIDS incidence and mortality. METHODS AND FINDINGS: A retrospective cohort study carried out in Brazil from January 1, 2007 to December 31, 2015. We conducted an impact evaluation using a cohort of 3,435,068 ≥13 years low-income individuals who were members of the 100 Million Brazilians Cohort, linked to AIDS diagnoses and deaths registries. We evaluated the impact of FHS on AIDS incidence and mortality and compared outcomes between residents of municipalities with low or no FHS coverage (unexposed) with those in municipalities with 100% FHS coverage (exposed). We used multivariable Poisson regressions adjusted for all relevant municipal and individual-level demographic, socioeconomic, and contextual variables, and weighted with inverse probability of treatment weighting (IPTW). We also estimated the FHS impact by sex and age and performed a wide range of sensitivity and triangulation analyses; 100% FHS coverage was associated with lower AIDS incidence (rate ratio [RR]: 0.76, 95% CI: 0.68 to 0.84) and mortality (RR: 0.68, 95%CI: 0.56 to 0.82). FHS impact was similar between men and women, but was larger in people aged ≥35 years old both for incidence (RR: 0.62, 95% CI: 0.53 to 0.72) and mortality (RR: 0.56, 95% CI: 0.43 to 0.72). The absence of important confounding variables (e.g., sexual behavior) is a key limitation of this study. CONCLUSIONS: AIDS should be an avoidable outcome for most people living with HIV today and our study shows that FHS coverage could significantly reduce AIDS incidence and mortality among low-income populations in Brazil. Universal access to comprehensive healthcare through community-based PHC programs should be promoted to achieve the Sustainable Development Goals of ending AIDS by 2030.

RÉSUMÉ

BACKGROUND: As new and improved antigen-detecting rapid diagnostic tests for SARS-CoV-2 infection (Ag-RDT) continue to be developed, assessing their diagnostic performance is necessary to increase test options with accurate and rapid diagnostic capacity especially in resource-constrained settings. This study aimed to assess the performance of two Ag-RDTs in a population-based study. METHODS: We conducted a diagnostic accuracy study in neighborhoods with high socioeconomic vulnerability in Salvador-Brazil, including individuals aged ≥12 years old who attended primary health services, between July and December 2022, with COVID-19 symptoms or who had been in contact with a confirmed case. Two Ag-RDTs were compared in parallel using reverse transcription polymerase chain reaction (RT-PCR) as reference standard, the PanbioTM COVID-19 Ag test (Abbott®) and Immuno-Rapid COVID-19 Ag (WAMA Diagnostic®). Sensitivity, specificity, positive (PPV) and negative predictive values (NPV) were calculated. RESULTS: For the Abbott test the sensitivity was 52.7% (95% CI: 44.3% - 61.0%), specificity 100% (95% CI: 98.7% - 100%), PPV 100% (95% CI: 95.4% - 100%) and NPV 80.4% (95% CI: 75.9% - 84.4%). For the WAMA test, the sensitivity was 53.4% (95% CI: 45.0% - 61.6%), specificity 100% (95% CI: 98.7% - 100%), PPV 100% (95% CI: 95.4% - 100%) and NPV 80.7% (95% CI: 76.2% - 84.6%). Sensitivity for the group with Cycle Threshold (CT) <24 was 82.3% (95%CI: 72.1-90.0, n = 83) for PanbioTM COVID-19 Ag test and 87.3% (95%CI: 77.9-93.8, n = 83) for Immuno-Rapid COVID-19 Ag test. CONCLUSION: Sensitivity for both Ag-RDT was lower than reported by manufacturers. In the stratified analysis, sensitivity was higher among those with lower CT values <24. Specificity was high for both rapid antigen tests. Both Ag-RDT showed to be useful for rapid diagnostic of potential cases of COVID-19. Negative results must be assessed carefully according to clinical and epidemiological information.

RÉSUMÉ

This study aims to estimate the COVID-19 vaccine acceptance and hesitancy among people living with HIV (PLWHA). A search for observational studies was conducted in five databases and preprinted literature. Summary estimates were pooled using a random effects model and meta-regression. Of 150 identified studies, 31 were eligible (18,550 PLWHA). The weighted prevalence of COVID-19 vaccine hesitancy overall was 29.07% among PLWHA (95%CI = 24.33-34.32; I² = 98%,) and that of vaccine acceptance was 68.66% (95%CI = 62.25-74.43; I² = 98%). Higher hesitancy prevalence was identified in low/lower-middle income countries (35.05; 95% CI = 19.38-54.78). The heterogeneity was explained by the risk of bias, region, and year of data collection. The findings conclude that the COVID-19 vaccine hesitancy rate remains high, especially in low-income countries. Evidence-informed interventions aimed at increasing COVID-19 vaccine acceptance at the national and individual levels ought to be designed to increase COVID-19 vaccine acceptance among PLWHA.

RÉSUMÉ

This study aimed to analyze the challenges in demand creation for participation in an HIV pre-exposure prophylaxis (PrEP) project in two Brazilian capitals. This qualitative study was conducted with men who have sex with men and transgender women aged 15 to 19 years who lived in two Brazilian state capitals. For this analysis, 27 semi-structured interviews carried out from 2019 to 2020 were evaluated by reflexive thematic content analysis. For participants, PrEP demand creation was essential for their interaction, mediation, bonding, and attachment and proved effective for PrEP acceptability and adherence. Adolescents' narratives showed that the strategies promoted HIV combination prevention, opened up opportunities for recruitment meetings, helped to negotiate with and convince individuals to use PrEP, strengthened peer education, and evoked a feeling of "being with" and "walking together" despite the challenges. Face-to-face or online interactions using social technologies played a crucial role in recruiting adolescents for the project, expanding knowledge on PrEP and other combination prevention strategies and access to health services and self-care.

RÉSUMÉ

The relationships between race, education, wealth, their intersections and AIDS morbidity/mortality were analyzed in retrospective cohort of 28.3 million individuals followed for 9 years (2007-2015). Together with several sensitivity analyses, a wide range of interactions on additive and multiplicative scales were estimated. Race, education, and wealth were each strongly associated with all of the AIDS-related outcomes, and the magnitude of the associations increased as intersections were included. A significantly higher risk of illness (aRR: 3.07, 95%CI:2.67-3.53) and death (aRR: 4.96, 95%CI:3.99-6.16) from AIDS was observed at the intersection of Black race, lower educational attainment, and less wealth. A higher case-fatality rate (aRR: 1.62, 95%CI:1.18-2.21) was also seen for the same intersectional group. Historically oppressed groups lying at the intersections of race, education, and wealth, had a considerably higher risk of illness and death from AIDS. AIDS-related interventions will require the implementation of comprehensive intersectoral policies that follow an intersectionality perspective.

RÉSUMÉ

Many barriers to human immunodeficiency virus (HIV) testing among Black people exist. This study analysed the association between race/skin colour and lifetime HIV testing among adolescent men who have sex with men (AMSM) and transgender women (ATGW) in three Brazilian cities. This cross-sectional study was nested within the PrEP1519 cohort, a multicentre study of AMSM and ATGW aged 15-19 years in Belo Horizonte, Salvador, and São Paulo, Brazil. The outcome variable was the lifetime HIV testing (no or yes). The main exposure variable was self-reported race/skin colour as White and a unique Black group (composed of Pardo-mixed colour and Black, according to the Brazilian classification). Descriptive statistics and bivariate and multiple logistic regression analyses were conducted to estimate the adjusted odds ratios (ORs) and 95% confidence intervals (95% CIs) to determine the association between the main exposure and outcome, adjusted for covariates. White adolescents were tested more frequently than the unique Black group (64.0% vs. 53.7%, respectively; Ρ = 0.001). Multiple logistic regression analysis showed that the unique Black group of AMSM and ATGW had 26% (adjusted OR [aOR], 0.74; 95% CI, 0.55-0.98) and 38% (aOR, 0.62; 95% CI, 0.45-0.87) lower odds of being tested for HIV in a lifetime than Whites in model 1 and 2, respectively. Our findings highlight the role of racism in lifetime HIV testing among AMSM and ATGW. Therefore, an urgent need for advances exists in public policies to combat racism in Brazil.


RESUMEN: Existen numerosas barreras para la realización de las pruebas del virus de la inmunodeficiencia humana (VIH) entre la población negra. Este estudio analizó la asociación entre la raza/color de piel y haber realizado pruebas de VIH a lo largo de la vida entre hombres adolescentes que tienen sexo con hombres (AHSH) y mujeres transgénero (AMTG) en tres ciudades brasileñas. Este estudio transversal es parte de la cohorte PrEP1519, un estudio multicéntrico de AHSH y AMTG de 15 a 19 años en Belo Horizonte, Salvador y São Paulo, Brasil. La variable de resultado fue haber realizado la prueba del VIH a lo largo de la vida (no o sí). La variable de exposición principal fue la raza/color de piel autoinformada, categorizada como blanca y un grupo negro único (compuesto por color pardo/mixto y negro, según la clasificación brasileña). Se realizaron estadísticas descriptivas y análisis de regresión logística bivariada y multivariada para estimar los odds ratios (OR) ajustados y los intervalos de confianza del 95% (IC del 95%) con el fin de determinar la asociación entre la exposición principal y el resultado, ajustado por covariables. Los adolescentes blancos se hicieron la prueba del VIH con más frecuencia que el grupo negro único (64,0% frente a 53,7%, respectivamente; Ρ = 0,001). El análisis de regresión logística múltiple reveló que el grupo negro único de AHSH y AMTG tenía 26% (OR ajustado [aOR], 0,74; IC 95%, 0,55­0,98) y 38% (aOR, 0,62; IC 95%, 0,45­0,87) menores probabilidades de realizarse la prueba del VIH a lo largo de su vida que los blancos en los modelos 1 y 2, respectivamente. Nuestros hallazgos resaltan la influencia del racismo en la realización de pruebas de VIH a lo largo de la vida entre AHSH y AMTG. Por lo tanto, es urgente avanzar en la implementación de políticas públicas para combatir el racismo en Brasil.

RÉSUMÉ

BACKGROUND: The effective testing of sexually transmitted infections (STIs) requires sampling from potential infection sites. This study aimed to assess the choice, satisfaction, and performance of self-collected samples (SCS) from potential infection sites for STI testing among transgender women in Brazil. METHODS: TransOdara was a multicentric, cross-sectional STI prevalence study conducted in 5 Brazilian cities. Using respondent-driven sampling, 1317 transgender women 18 years or older were recruited. Participants completed interviewer-led questionnaires and provided swab samples from multiple sites (anorectal, oropharyngeal, genital) for Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), and human papillomavirus (HPV) testing. Participants were given a choice of SCS or provider-collected samples (PCS) at each site. RESULTS: Most participants selected SCS for anorectal (74.9%; 95% confidence interval [CI], 72.4-77.3) and genital (72.7%; 95% CI, 70.2-75.1) sites, whereas fewer chose for oropharyngeal samples (49.8%; 95% CI, 47.0-52.6). For future testing, most participants expressed a preference for SCS for genital (72.2%; 95% CI, 69.5-74.7) and anorectal (70.2%; 95% CI, 67.6-72.7) sites. There was no significant difference in the positive test results for CT and NG between SCS and PCS at anorectal and oropharyngeal sites, or for HPV at anorectal and genital (penile or neovaginal) sites. CONCLUSIONS: This study demonstrated a high level of acceptability and usability of self-sampling for STI testing among transgender women. A preference for SCS was evident at the anorectal and genital sites, and the results of SCS were comparable to those of PCS. The findings suggest that multisite STI testing utilizing self-collection methods as a provided option can be effectively integrated into sexual health services for transgender women.

RÉSUMÉ

Living with extremely low-income is an important risk factor for HIV/AIDS and can be mitigated by conditional cash transfers. Using a cohort of 22.7 million low-income individuals during 9 years, we evaluated the effects of the world's largest conditional cash transfer, the Programa Bolsa Família, on HIV/AIDS-related outcomes. Exposure to Programa Bolsa Família was associated with reduced AIDS incidence by 41% (RR:0.59; 95%CI:0.57-0.61), mortality by 39% (RR:0.61; 95%CI:0.57-0.64), and case fatality rates by 25% (RR:0.75; 95%CI:0.66-0.85) in the cohort, and Programa Bolsa Família effects were considerably stronger among individuals of extremely low-income [reduction of 55% for incidence (RR:0.45, 95% CI:0.42-0.47), 54% mortality (RR:0.46, 95% CI:0.42-0.49), and 37% case-fatality (RR:0.63, 95% CI:0.51 -0.76)], decreasing gradually until having no effect in individuals with higher incomes. Similar effects were observed on HIV notification. Programa Bolsa Família impact was also stronger among women and adolescents. Several sensitivity and triangulation analyses demonstrated the robustness of the results. Conditional cash transfers can significantly reduce AIDS morbidity and mortality in extremely vulnerable populations and should be considered an essential intervention to achieve AIDS-related sustainable development goals by 2030.

RÉSUMÉ

BACKGROUND: Migration is common among transgender women (TGW), often driven by the desire to escape stigma, find acceptance, establish new connections, access body modifications, or enter new avenues of sex work. Given the heightened mobility of TGW, they are mostly vulnerable to human immunodeficiency virus (HIV) due to migration. This study aimed to evaluate the association between in-country migration and HIV infection among TGW in Northeast Brazil. METHODS: The DIVAS was a cross-sectional, multicity study investigating risk behaviors and sexually transmitted infections (STI) among TGW in 2016-2017. A total of 864 TGW were recruited through respondent-driven sampling from three capital cities in Northeast Brazil. Logistic regression estimating odds ratios (OR) and 95% confidence intervals (CI) was used to assess the relationship between in-country migration and HIV infection. RESULTS: The prevalence of HIV among TGW was 24.5%, 21.4% among those aged 18-34 and 36.1% among those ≥ 35 years old. In-country migration increased the odds of HIV infection among TGW aged 18-34 years (OR = 1.84; 95%CI:1.04-3.27) and even higher among those aged ≥ 35y old (OR = 3.08; 95%CI:1.18-8.04). CONCLUSIONS: These data reinforce the pressing need for public health policies that provide comprehensive access and strategies for demand creation for HIV/AIDS prevention and care for TGW who are already highly vulnerable to infection.

RÉSUMÉ

ABSTRACT: We evaluated the quality of care provided by the nursing team within specialized care services (SCS) from the perspective of persons with HIV (PWH). A cross-sectional study was conducted in 25 SCS selected by a single-stage cluster sampling in 21 municipalities in Brazil. Systematic sampling was performed between October 2019 and March 2020 in the reception areas of SCS locations to choose the study population ( N = 377). The adapted and validated Quality of Care Through the Patient's Eyes-HIV (QUOTE-HIV) questionnaire was used to measure the quality of perceived care, and the Mann-Whitney test to compare the scores between men and women. Of the 377 PWH, most were women (57.71%), Black or Brown (85.9%), heterosexual (67.1%), and cisgendered (96.0%); the mean age was ≥30 years (76.1%). Users' evaluation of the care provided by SCS according to scores of importance and performance of the QUOTE-HIV instrument ranged from 5.60 to 8.95 and 0.03 to 0.76, respectively. The perception of PWH about the quality of care provided by the nursing team in SCS suggests that there are opportunities to improve.

RÉSUMÉ

The adverse effects of oral pre-exposure prophylaxis (PrEP) using tenofovir disoproxil fumarate are barriers to PrEP initiation and continuation. Although serious effects are rare and predictable, evidence for this assessment among men who have sex with men (MSM) and transgender women (TGW) is still limited. This study assesses the adverse effects of daily oral PrEP in MSM and TGW. This is a systematic review and meta-analysis of clinical trials and cohort studies on the use of daily oral PrEP selected from the PubMed/MEDLINE, Embase, LILACS, and Cochrane CENTRAL databases. Data extraction included adverse effects and changes in renal and hepatic markers. Random effects models were used to summarize the risk of adverse effects throughout the study. Heterogeneity was assessed using the Cochran's Q test and the inconsistency test (I2). The risk of bias and the certainty of the evidence were assessed using the Cochrane Collaboration recommendations. The search identified 653 references. Of these, 10 were selected. All studies assessed the eligibility of renal and hepatic markers. The use of daily oral PrEP was not associated with grade 3 or 4 adverse events (RR = 0.99; 95%CI: 0.83-1.18; I2 = 26.1%), any serious adverse event (RR = 1.04; 95%CI: 0.58-1.87; I2 = 88.4%), grade 3+4 creatinine level (RR = 0.66; 95%CI: 0.24-1.84; I2 = 79.9%), and grade 3 or 4 hypophosphatemia (RR = 0.56; 95%CI: 0.15-2.10). The certainty of the evidence ranged from high to moderate for the outcomes analyzed. Daily oral PrEP is safe and well tolerated by MSM and TGW. Adverse effects were minimal and evenly distributed between intervention and control.

RÉSUMÉ

The HIV epidemic has a disproportionate impact on adolescent and young men who have sex with men (AMSM) and transgender women and travestis (ATGW), with an increased HIV prevalence over the last 10 years. Violence affects the lives of these populations, undermining their ability to self-care and making them more vulnerable to HIV infection. In this study, we aimed to examine the association between different types of victimization by violence and discrimination and sexual health practices of these adolescent populations in steady and casual relationships. We conducted a cross-sectional study using baseline data from the cohort of PrEP1519 project. We used the mean score of sexual health practices as our outcome and the cumulative score of discrimination (within family, community, education, religious, online and public spaces) and violence (physical, sexual and intimate partner) as our exposure variable. We performed linear regression analyses to estimate the association between exposure and outcome. We found that 90% of AMSM and 95% of ATGW experienced at least one form of violence in the three months prior to this study and about 45% of ATGW suffered sexual violence during the same period. Experiencing discrimination within healthcare settings (from facilities or providers) was negatively associated with sexual health practices. Discrimination and violence negatively affect sexual health practices. HIV prevention and care of AMSM and ATGW people should involve listening to their experiences and addressing discrimination and violence in this population.

RÉSUMÉ

The United Nations has underscored the possibility of ending the HIV epidemic as a public health problem. However, an increase in the incidence among adolescents and youth has indicated a greater distance between HIV responses and the specificities of the new generations, which can maintain the epidemic for an extended period. Regards this matter, it is debated that the provision of a range of preventive methods, even if highly effective, and a conservatism that has internalized stigma within government policies, hinder the proper and essential dialogue between current preventive policies and the needs of the new generations. These generations are marked by a social representation of AIDS as a mild disease, by new gender and sexuality performances, and by the search for a more critical role in affective and sexual encounters, which includes frequent use of dating apps and substances. The hierarchy of the delivery of prevention methods is presented as a proposal for a new policy, prioritizing pre-exposure prophylaxis (PrEP) and addressing the social determinants of the HIV epidemic, including strategies to mitigate stigma. The importance of the participation of adolescents and youth in constructing the policy and the need for an intersectoral response are also reinforced.


A Organização das Nações Unidas tem destacado a possibilidade de eliminar a epidemia de HIV como um problema de saúde pública. Porém, um aumento da incidência em adolescentes e jovens tem indicado um maior distanciamento entre a resposta ao HIV e as especificidades próprias das novas gerações, que pode estender a epidemia por um longo período. Frente a isso, é discutido que a oferta de uma cesta universal de métodos preventivos, mesmo que altamente eficazes, e um conservadorismo que internalizou o estigma em políticas governamentais, inviabilizam o adequado e necessário diálogo entre as atuais políticas preventivas e as necessidades das novas gerações. Estas gerações que são marcadas por uma representação social da aids com menor gravidade; novas performances de gênero e de orientação sexual; e a busca de um maior protagonismo nas interações afetivas e sexuais, o que inclui o uso mais frequente de aplicativos de encontro de parcerias e de substâncias na cena de sexo. É apresentado como proposta de uma nova política a hierarquização da oferta de métodos preventivos, com a priorização da profilaxia pré-exposição (PrEP) e o enfrentamento dos determinantes sociais da epidemia do HIV, incluindo estratégias de redução do estigma. Reforça-se, ainda, a importância da participação de adolescentes e jovens na construção da política e a necessidade de uma resposta intersetorial.


Las Naciones Unidas señalan la posibilidad de eliminar la epidemia del VIH como un problema de salud pública. Sin embargo, un incremento de la incidencia de esta enfermedad en adolescentes y jóvenes muestra una mayor distancia entre la respuesta al VIH y las especificidades de las nuevas generaciones, lo que puede extender la epidemia durante un largo periodo. En este contexto, se discute que la oferta de una canasta universal de métodos preventivos, aunque altamente efectivos, y que un conservadurismo que interiorizó el estigma en las políticas gubernamentales hacen inviable un adecuado y necesario diálogo entre las políticas preventivas actuales y las necesidades de las nuevas generaciones. Estas generaciones están marcadas por una representación social del sida con menos gravedad, por nuevas actuaciones de género y orientación sexual y por la búsqueda de un mayor protagonismo en las interacciones afectivas y sexuales, que incluye el uso más frecuente de aplicaciones para encontrar parejas y de sustancias en la escena sexual. Se presenta como propuesta de una nueva política la priorización de la oferta de métodos preventivos, con la priorización de la profilaxis preexposición (PrEP) y la confrontación de los determinantes sociales de la epidemia del VIH, que incluyen estrategias para reducir el estigma. También refuerza la importancia de la participación de los adolescentes y jóvenes en la construcción de la política y la necesidad de una respuesta intersectorial.

RÉSUMÉ

BACKGROUND: Men who have sex with men (MSM) and transgender women (TGW) have a disproportionately higher risk of human immunodeficiency virus (HIV) infection than other groups. Oral HIV pre-exposure prophylaxis (PrEP) is an effective prevention tool and should be offered to those at higher risk. Identifying demand creation strategies (DCS) and retention strategies (RS) to improve PrEP persistence is essential to control the HIV epidemic. AIM: We aimed to identify the (DCS and RS with higher proportions among MSM and TGW. METHODS: A systematic review and meta-analysis of prospective studies were conducted, with studies retrieved from five databases until November, 2022 following the Cochrane and PRISMA guidelines. The study protocol was registered in PROSPERO (CRD42022323220). The outcomes were DCS and RS for PrEP use among MSM and TGW. Strategies used for users enrolled in the PrEP-recruited (DCS) were classified as face-to-face (peer educator recruitment at social venues, nongovernmental organizations, and parties; direct referrals by health services; friends and/or sexual partners); online (chatbot or peer educator recruitment on social media [e.g., , Instagram or Facebook] or dating/hook-up apps [e.g., Grindr, Tinder, Badoo, and Scruff]); and mixed (face-to-face and online). RS was classified as provider counseling (face-to-face by a health professional; prevention of HIV risk counseling, distribution of condoms, lubricants, and testing for HIV or other sexually transmitted infections); online counseling (text messages, chatbots, telephone calls, social media, and peer educators); and mixed (all previous strategies). Subgroup analyses were conducted for each treatment strategy. Meta-analyses were performed using the R software version 4.2.1. RESULTS: A total of 1, 129 studies were retrieved from the five databases. After eligibility, 46 studies were included. For MSM, most DCS and RS were online at 91% (95% CI: 0.85-0.97; I2=53%), and 83% (95% CI: 0.80-0.85; I2=17%) respectively. For TGW, mixed DCS and RS were the most frequent at85% (95% CI: 0.60-1.00; I2=91%) and online counseling at 84% (95% CI: 0.64-0.95) compared to other strategies. CONCLUSION: Critical issues play. Pivotal role in increasing PrEP awareness among MSM and TGW, minimizing access gaps, and ensuring retention of PrEP services. Offering oral PrEP using online DCS and RS can reach and retain high numbers of MSM and TGW, and reduce HIV incidence in these populations.

RÉSUMÉ

PURPOSE: To explore legal and ethical challenges related to adolescents' participation in human immunodeficiency virus (HIV) research that may affect their best interests. METHODS: We analyzed the ethical principles and legal aspects of the participation of 15-17-year-old men who have sex with men and transgender women in the pre-exposure prophylaxis (PrEP) 1519 study, a PrEP demonstration cohort study in three Brazilian cities. The analyses of ethics review committees' (ERCs) evaluations and court decisions followed ethical and human rights principles. An HIV vulnerability score was created, and descriptive statistics and multivariate logistic regression were performed using data from 347 participants. RESULTS: The ERCs evaluated the benefits and risks of research participation, all finding that the benefits outweighed the risks. ERCs deferred responsibility for decisions about waiving parental consent to the judiciary. State courts reached different decisions about waiving parental consent, reflecting variation in recognition of adolescents' evolving capacities and the adolescent as a subject of sexual rights and the primary agent capable of deciding on their health and best interests. The most vulnerable adolescent participants were found in sites where the blanket waiver was in place. DISCUSSION: Judicializing the ethical review process is detrimental to fulfilling the ethical principle of justice and vulnerable adolescents' access to health research. ERCs must be sufficiently independent and autonomous and have the capacity to respect, protect, and help fulfill the rights of participants while ensuring the generation of adequate evidence to inform public health practice.

RÉSUMÉ

PURPOSE: This study aimed at describing the prevalence of symptoms of depression among 15-19 year old adolescent men who have sex with men (aMSM) and transgender women (aTGW), who were recruited in an HIV pre-exposure prophylaxis cohort study in three Brazilian capital cities. The study also examined potential associations, including violence and discrimination, with severe symptoms of depression among aMSM. METHODS: This is a cross-sectional study of baseline data among 730 aMSM and 56 aTGW recruited between February 2019 and February 2021. Sociodemographic and behavioral data were collected. The 20-item Center for Epidemiologic Studies Depression scale was used to screen for symptoms of depression. Scores of ≥22 points indicate the presence of severe symptoms associated with major depression. Logistic regression was used to assess independent associations among aMSM, adjusting for sociodemographic variables. RESULTS: Our findings indicate a high prevalence of symptoms of depression (overall prevalence = 58.5% and 69.6%; 21.2% and 25.0% for mild/moderate, and 37.3% and 44.6% for severe) among these aMSM and aTGW, respectively. Psychological violence (aOR = 1.74; 95% CI = 1.12-2.70), sexual violence (aOR = 1.79; 95% CI = 1.07-2.98), and discrimination due to sexual orientation (aOR = 1.71; 95% CI = 1.23-2.38) were independently associated with severe symptoms of depression in aMSM. DISCUSSION: The high prevalence of severe symptoms of depression and its association with psychological and sexual violence and discrimination creates cycles of vulnerability and carries important public health implications. Thus, our findings indicate public policies should consider assessing depression, psychological and sexual violence, as well as discrimination, especially in populations that will be targeted by interventions, such as the use of pre-exposure prophylaxis.
