Individual and Collective Forms of Stigma Resistance: Pathways Between HIV and Sex Work Stigma and Viral Suppression Among Female Sex Workers in the Dominican Republic.

Intersecting forms of stigma including both HIV and sex work stigma have been known to impede HIV prevention and optimal treatment outcomes among FSW. Recent research has indicated that intersectional stigma can be resisted at the community and individual level. We assessed pathways between HIV stigma, sex work stigma, social cohesion and viral suppression among a cohort of 210 FSW living with HIV in the Dominican Republic. Through Poisson regression we explored the relationship between HIV outcomes and internalized, anticipated and enacted HIV and sex work stigma, and resisted sex work stigma. We employed structural equation modeling to explore the direct effect of various forms of stigma on HIV outcomes, and the mediating effects of multi-level stigma resistance including social cohesion at the community level and occupational dignity at the individual level. 76.2% of FSW were virally suppressed and 28.1% had stopped ART at least once in the last 6 months. ART interruption had a significant negative direct effect on viral suppression (OR = 0.26, p < 0.001, 95% CI: 0.13-0.51). Social cohesion had a significant positive direct effect on viral suppression (OR = 2.07, p = 0.046, 95% CI: 1.01-4.25). Anticipated HIV stigma had a significant negative effect on viral suppression (OR = 0.34, p = 0.055, 95% CI: 0.11-1.02). This effect was mediated by the interaction between cohesion and dignity which rendered the impact of HIV stigma on viral suppression not significant. Findings demonstrate that while HIV stigma has a negative impact on viral suppression among FSW, it can be resisted through individual and collective means. Results reinforce the importance of community-driven, multi-level interventions.

High burden of sexually transmitted infections among under-resourced populations in the Dominican Republic.

Background: Sexually transmitted infections (STIs) are a major health issue, exacerbated by limited financial and infrastructural resources in developing countries. Methods: Prevalence of STIs was assessed in two urban centers of the Dominican Republic (DR) among populations at high risk for STIs: pregnant youth, men who have sex with men (MSM), trans women (TG), batey residents, female sex workers, and people living with human immunodeficiency virus (HIV). We conducted a cross-sectional survey and biological specimen collection to screen for Chlamydia trachomatis, Neisseria gonorrhea, Mycoplasma genitalium, Trichomonas vaginalis (trichomoniasis), Treponema pallidum (syphilis), HIV, hepatitis B and C, and human papillomavirus (HPV) among at-risk populations between 2015 and 2018. Ureaplasma urealyticum testing was also conducted even though it is not considered a STI. A non-probability community sample was recruited. Descriptive statistics examined the prevalence of STIs by population. Results: A total of 1991 subjects participated in the study. The median age was 26 years (range: 18-65). Most participants were female (65.3%), heterosexual (76.7%), and were not partnered (55.7%). Most of the participants reported unprotected vaginal sex in the last 6 months (54%); among MSM and TG almost half of the participants reported unprotected anal sex in the last 6 months and 17.6% reported drug use in the last 6 months. Almost half of the participants (49%) tested positive for one or more STIs. The most prevalent STI was Chlamydia trachomatis (12.8%), and human papillomavirus (11.9%). Among transgender women, 65.3% tested positive for an STI, 64.8% of female sex workers tested positive for an STI, and 53.8% of pregnant adolescents tested positive for an STI. Conclusion: There is a high prevalence of STIs among key and under resourced populations in the DR. Our findings highlight the need to conduct further research to optimize prevention and care strategies for structurally vulnerable and under resourced populations in the DR.

Comparing typologies of violence exposure and associations with syndemic health outcomes among cisgender and transgender female sex workers living with HIV in the Dominican Republic.

Violence against women research largely excludes transgender women's experiences and violence from perpetrators other than intimate partners. This study compares patterns of violence exposure among cisgender and transgender female sex workers (FSWs) and the associations with syndemic health outcomes. We used cross-sectional surveys from samples of cisgender and transgender FSWs living with HIV in the Dominican Republic (N = 211 and 100, respectively). We used latent class analysis to identify patterns of emotional, physical, and sexual violence and harassment by partners, clients, and police. We assessed sociodemographic and occupational predictors in relation to class membership, and class membership in relation to health (HIV continuum of care outcomes, mental health, substance use), using logistic regression. Two classes were identified in cisgender sample: Low Reported Violence Exposure (Class 1) and Sex Work-related Police Harassment (Class 2). Class 2 participants had greater odds of scoring abnormal or borderline abnormal anxiety on the Hospital Anxiety and Depression Scale (HADS-A) (adjusted OR = 3.97, p<0.01), moderate-to-severe depression per the Patient Health Questionnaire-9 (PHQ-9) (aOR = 5.74, p<0.01), and any illicit drug use in the past six months (aOR = 3.06, p<0.05), compared to Class 1. The transgender sample produced three classes: Low Reported Violence Exposure (Class 1); Sex Work-related Police Harassment (Class 2); and Sex Work-related Violence and Harassment (Class 3). Class 3 participants had greater odds of having anxiety (aOR = 6.65, p<0.01) and depression (aOR = 4.45, p<0.05), while Class 2 participants had greater odds of perfect ART adherence during the previous four days (aOR = 2.78, p<0.05), compared to Class 1. The more diverse and extreme violence patterns uncovered for the transgender sample show this group's heightened risk, while similar patterns across groups regarding police abuse highlight a need for police-focused violence prevention interventions. Each sample's highest violence class was associated with poor mental health, underscoring the need for mental health interventions for all FSWs.

Beyond a deficit-based approach: Characterizing typologies of assets for cisgender and transgender female sex workers and their relationship with syndemic health outcomes.

Female sex workers (FSWs) live and work at the intersection of multiple marginalized identities that place them at greater risk for various negative health outcomes. Resilience theory asserts that an individual or community needs assets from which they can draw in response to stressors, such as chronic discrimination and abuse. This study characterizes and compares patterns of assets among cisgender and transgender FSWs living with HIV in the Dominican Republic and their relations with syndemic health outcomes. With Latent Class Analysis, we used companion cross-sectional datasets comprised of cisgender and transgender FSWs (N = 211 and 100, respectively) to estimate typologies of interpersonal, community, and institutional assets. We used multivariate logistic regression to model the relationship between class membership and HIV care and treatment, mental health, violence exposure, and substance use outcomes, respectively. Among cisgender FSWs, we identified three classes: Internal and External Multilevel Assets (Class 1); External Institutional Assets (Class 2); and Low Reported Assets (Class 3). Compared to Class 3, Class 1 membership among cisgender FSWs was significantly associated with ART adherence and marginally associated with viral suppression, and Class 2 membership was marginally associated with currently taking ART. We identified two classes in the transgender sample: Internal and External Multilevel Assets (Class 1) and External Institutional Assets (Class 2). Class 1 membership among transgender FSWs was significantly associated with ART adherence and marginally associated with current ART use and physical or sexual violence, compared to Class 2. Having a variety of assets may explain the ability of some FSWs to more effectively engage with healthcare and maintain their HIV medication regimen. Future interventions should seek to expand FSWs' interpersonal and community assets, both from within and outside of the sex worker community, to bolster their ability to care for themselves and their community.

Exploring the dynamics of the quality of HIV care experienced by female sex workers living in the Dominican Republic.

Despite increased attention and efforts to improve HIV care among female sex workers (FSWs), they continue to have suboptimal HIV outcomes. Exploring the socio-structural dynamics related to the quality of HIV care received by FSWs is critical to further strengthen interventions to improve their HIV care continuum outcomes. In this study, we conducted two rounds of qualitative in-depth interviews with 20 FSWs living with HIV in the Dominican Republic to explore how healthcare experiences contributed to their quality of HIV care. Data was analyzed using a thematic analytic approach exploring diverse structural and relational aspects of the quality of HIV care affecting FSWs as they navigate the clinic environment. Results indicated that quality of HIV care was influenced by both structural and relational factors within clinics. At the structural level, insufficient stock of antiretroviral therapy and the financial burden created by HIV care related costs hindered FSWs' satisfaction with their current HIV care and presented a barrier in FSWs' ability to access HIV care services. Quality of care was also closely linked to relational aspects of the HIV care environment, including FSWs' relationship and communication with their clinical providers, as FSWs often expressed their satisfaction with HIV care experiences based on these interpersonal factors. Lastly, personal agency emerged as an important factor contributing to the quality of HIV care, specifically as FSWs' treatment literacy resulted in greater advocacy and demands for quality care. Programmatic efforts should be directed to improving the quality of HIV care experiences of FSWs in the clinic environment. These include addressing resource shortages, promoting positive and effective patient-provider relationships, and facilitating HIV treatment education opportunities for FSWs.

Stigma and HIV Treatment Outcomes Among Transgender Women Sex Workers in the Dominican Republic.

Trans women experience multiple forms of intersecting stigma due to trans identity, HIV, and sex work, which can negatively affect their health. There is limited understanding of the relationships between stigma and HIV care and treatment outcomes. We assessed associations between multiple forms and types of stigma and HIV treatment outcomes among trans women who conduct sex work in Santo Domingo, Dominican Republic using cross-sectional survey data. Most participants had received HIV care (91%) and were currently taking anti-retroviral therapy (ART) (84%). Only 64% were virally suppressed. Nearly one-third (32%) had interrupted ART at some point; those who had never interrupted ART were more likely to be suppressed. Drug use was associated with ART interruption. Higher enacted HIV stigma was associated with current ART use. Higher enacted HIV stigma and higher anticipated sex work stigma were associated with ART adherence. Higher trans stigma was associated with being virally suppressed. Findings highlight the importance of addressing multiple forms of stigma at the individual and clinic levels to improve and sustain viral suppression. Future research is needed to assess if unexpected associations between stigma and HIV outcomes reflect processes of resilience. Future research is also needed to assess the pathways between drug use, ART interruption, and viral suppression among trans women.

Trajectories of HIV management among virally suppressed and unsuppressed female sex workers in the Dominican Republic: A comparative qualitative analysis.

PURPOSE: Despite suboptimal HIV outcomes among female sex workers (FSW), limited research has been conducted on factors that impact viral suppression among this population. Examining narratives of HIV management, we examined how experiences of diagnosis, treatment initiation, and ongoing care behaviours shaped viral suppression outcomes over time. METHODS: We conducted 20 in-depth interviews with FSW in Santo Domingo, Dominican Republic. Using narrative and thematic qualitative approaches, we developed analytic summaries and matrices to compare trajectories of managing HIV between suppressed and unsuppressed participants. RESULTS: Regardless of suppression status, participants described similar narratives of overcoming initial challenges to HIV management through personal resilience and social support. Unsuppressed participants identified more delays in initiating antiretroviral therapy and more lapses in adherence due to less active acceptance of their HIV status and more persistent experiences of economic hardship and HIV stigma. CONCLUSIONS: We found that individual, interpersonal and structural factors, including stigma and economic precarity, differentiated trajectories towards viral suppression among FSW indicating the importance of multilevel interventions. Improved access to mental health services and social support could promote greater early acceptance of HIV status and progress towards viral suppression among FSW.

Preliminary Effects of an Urban Gardens and Peer Nutritional Counseling Intervention on HIV Treatment Adherence and Detectable Viral Load Among People with HIV and Food Insecurity: Evidence from a Pilot Cluster Randomized Controlled Trial in the Dominican Republic.

A pilot cluster randomized controlled trial involving two HIV clinics in the Dominican Republic assessed preliminary efficacy of an urban garden and peer nutritional counseling intervention. A total of 115 participants (52 intervention, 63 control) with moderate or severe food insecurity and sub-optimal antiretroviral therapy (ART) adherence and/or detectable viral load were assessed at baseline, 6- and 12-months. Longitudinal multivariate regression analysis controlling for socio-demographics and accounting for serial cluster correlation found that the intervention: reduced the prevalence of detectable viral load by 20 percentage points at 12 months; reduced any missed clinic appointments by 34 and 16 percentage points at 6 and 12 months; increased the probability of "perfect" ART adherence by 24 and 20 percentage points at 6 and 12 months; and decreased food insecurity at 6 and 12 months. Results are promising and warrant a larger controlled trial to establish intervention efficacy for improving HIV clinical outcomes.Trial registry Clinical Trials Identifier: NCT03568682.

RESUMEN: Un estudio piloto de un ensayo controlado aleatorio por conglomerados que involucró a dos clínicas del VIH en la República Dominicana evaluó de forma preliminar la eficacia de una intervención de huertos urbanos y consejería nutricional entre pares. Un total de 115 participantes (52 de intervención, 63 de control) con inseguridad alimentaria moderada o grave y con adherencia subóptima a la terapia antirretroviral (TARV) y/o carga viral detectable fueron evaluados al inicio del estudio, y a los 6 y 12 meses. El análisis de regresión longitudinal multivariada controlando por variables sociodemográficas y tomando en cuenta la correlación serial de clúster encontró que la intervención: redujo la prevalencia de carga viral detectable en 20 puntos porcentuales a los 12 meses; redujo las citas clínicas perdidas en 34 y 16 puntos porcentuales a los 6 y 12 meses; aumentó la probabilidad de adherencia "perfecta" al TARV en 24 y 20 puntos porcentuales a los 6 y 12 meses; y disminuyó la inseguridad alimentaria a los 6 y 12 meses. Los resultados son prometedores y justifican un ensayo controlado más grande para establecer la eficacia de la intervención en mejorar los resultados clínicos del VIH.

Substance Use and Depression Impede ART Adherence Among Female Sex Workers Living with HIV in the Dominican Republic.

Female sex workers (FSW) have worse HIV outcomes in part due to lower anti-retroviral therapy (ART) adherence. Substance use and depression are important barriers to ART adherence, yet few studies have assessed these relationships among FSW in longitudinal studies. Cross-Lagged Panel Models and autoregressive mediation analyses assessed substance use (illicit drug use and alcohol use disorders) in relation to ART non-adherence and the mediation role of depressive symptoms among 240 FSW living with HIV in the Dominican Republic. In annual visits (T1, T2, T3), the majority (70%, 66%, and 53%) reported at-risk drinking and 15%, 13% and 9% used illicit drug during the past 6 months. Most FSW (70%, 62% and 46%) had mild-to-severe depression. Illicit drug use predicted later ART non-adherence. This relationship was not mediated via depressive symptoms. Integrated substance use and HIV care interventions are needed to promote ART adherence and viral suppression among FSW.

RESUMEN: Las trabajadoras sexuales (TRSX) tienen peores resultados de VIH debido en parte a la menor adherencia a la terapia antirretroviral (TAR). El uso de sustancias y la depresión son barreras importantes para la adherencia; sin embargo, pocos estudios longitudinales han evaluado estas relaciones entre las TRSX. Utilizamos modelos de panel y análisis de mediación para evaluar el uso de sustancias en relación a la falta de adherencia al TAR y el papel de mediación de los síntomas depresivos entre 240 TRSX con VIH en la República Dominicana. En visitas anuales (T1, T2, T3), la mayoría (70%, 66%, and 53%) reportó consumo riesgoso de alcohol y 15%, 13% y 9% consumieron alguna droga ilícita durante los últimos 6 meses. La mayoría (70%, 62% y 46%) tenían depresión leve a grave. El uso de drogas ilícitas predijo la falta de adherencia al TAR. Esta relación no fue mediada por síntomas depresivos. Se necesitan intervenciones integradas de atención del VIH y el uso de sustancias para promover la adherencia al TAR y la supresión viral entre TRSX.

Relationships Between Stigma and Intimate Partner Violence Among Female Sex Workers Living With HIV: Social and Economic Exclusion.

Violence against female sex workers (FSWs) perpetrated by their intimate (i.e., non-commercial) partners, particularly against FSWs living with HIV, is understudied. Stigma can deplete the economic resources, social relationships, and mental well-being of stigmatized people, which may increase their intimate partner violence (IPV) risk. We quantitatively assessed relationships between HIV stigma and sex work stigma and IPV victimization among FSWs living with HIV in the Dominican Republic (n = 266). Enacted HIV stigma, in the form of job loss, and anticipated HIV stigma, in the form of fear of exclusion by family, were associated with increased IPV risk. Potential association mechanisms, including increased economic vulnerability and social isolation, and programmatic responses are discussed.

A Two-stage Approach for Rapid Assessment of the Proportion Achieving Viral Suppression Using Routine Clinical Data.

BACKGROUND: Improving viral suppression among people with HIV reduces morbidity, mortality, and transmission. Accordingly, monitoring the proportion of patients with a suppressed viral load is important to optimizing HIV care and treatment programs. But viral load data are often incomplete in clinical records. We illustrate a two-stage approach to estimate the proportion of treated people with HIV who have a suppressed viral load in the Dominican Republic. METHODS: Routinely collected data on viral load and patient characteristics were recorded in a national database, but 74% of patients on treatment at the time of the study did not have a recent viral load measurement. We recruited a subset of these patients for a rapid assessment that obtained additional viral load measurements. We combined results from the rapid assessment and main database using a two-stage weighting approach and compared results to estimates obtained using standard approaches to account for missing data. RESULTS: Of patients with recent routinely collected viral load data, 60% had a suppressed viral load. Results were similar after applying standard approaches to account for missing data. Using the two-stage approach, we estimated that 77% (95% confidence interval [CI] = 74, 80) of those on treatment had a suppressed viral load. CONCLUSIONS: When assessing the proportion of people on treatment with a suppressed viral load using routinely collected data, applying standard approaches to handle missing data may be inadequate. In these settings, augmenting routinely collected data with data collected through sampling-based approaches could allow more accurate and efficient monitoring of HIV treatment program effectiveness.

Assessing the Relationship Between HIV Quality of Care and Treatment Literacy on ART Adherence and Viral Suppression Among Female Sex Workers Living in the Dominican Republic.

This study assessed the relationship between the quality of HIV care and treatment literacy on antiretroviral therapy (ART) adherence and viral suppression among female sex workers (FSWs) living with HIV (n = 211) in Santo Domingo, Dominican Republic. Multivariable logistic regression results indicate better patient-provider communication (AOR 1.04; 95% CI 1.01-1.07) and respectful treatment (AOR 2.17; 95% CI 1.09-4.32) increase the odds of viral suppression, while higher costs reduce both the odds of ART adherence (AOR 0.57, 95% CI 0.34- 0.95) and being virally suppressed (AOR 0.59, 95% CI 0.41-0.85). Greater treatment literacy was associated with an increased odds of ART adherence (AOR 4.15 for understanding of viral load; 95% CI 1.50-11.52) and viral suppression (AOR 2.75 for understanding of CD4 count; 95% CI 1.31-5.80). Findings support investments in treatment education, effective and respectful patient-provider communication, dignified care, and cost-support for associated HIV care costs to facilitate FSWs' pathway towards viral suppression.

RESUMEN: Este estudio evaluó la relación entre la calidad de la atención para el VIH y la alfabetización relacionada al tratamiento sobre la adherencia a la terapia antirretroviral (TAR) y la supresión viral entre las trabajadoras sexuales (TRSX) que viven con el VIH (n = 211) en Santo Domingo, República Dominicana. Los resultados de la regresión logística multivariable indican una mejor comunicación entre el paciente y el proveedor (RMa: 1.04; IC del 95%: 1.01­1.07) y un tratamiento respetuoso (RMa: 2.17; IC del 95%: 1.09­4.32) aumenta la probabilidad de supresión viral, mientras que los costos elevados reducen tanto las probabilidades de adherencia al TAR (RMa: 0.57; IC del 95%: 0.34­0.95) como la supresión viral (RMa: 0.59, IC del 95%: 0.41­0.85). Una mayor alfabetización relacionada al tratamiento se asoció con una mayor probabilidad de adherencia al TAR (RMa: 4.15 para la comprensión de la carga viral; IC del 95%: 1.50­11.52) y la supresión viral (RMa: 2.75 para la comprensión del conteo de CD4; IC del 95%: 1.31­5.80). Los hallazgos respaldan inversiones en educación sobre el tratamiento, la comunicación efectiva y respetuosa entre el paciente y el proveedor, la atención digna y el apoyo económico para los costos asociados con la atención del VIH para facilitar el camino de las TRSX hacia la supresión viral.

Structural and Psychosocial Impacts of the COVID-19 Pandemic on HIV Care and Treatment Outcomes Among Female Sex Workers in the Dominican Republic.

BACKGROUND: The COVID-19 pandemic and its associated socioeconomic disruptions have disproportionally affected marginalized populations, including people living with HIV. Little is known about how the pandemic has affected populations experiencing multiple forms of stigma, discrimination, and violence, such as female sex workers (FSW) living with HIV. METHODS: We conducted a cross-sectional survey between August and December 2020 among 187 FSW living with HIV in the Dominican Republic to examine the impact of COVID-19. Using multivariable logistic regression, we examined associations between COVID-19-related financial concerns, mental health, substance use, and partner abuse on engagement in HIV care and antiretroviral therapy adherence. We conducted mediation analysis to assess whether mental health challenges mediated the impact of partner abuse or substance use on HIV outcomes. RESULTS: Most participants reported no income (72%) or a substantial decline in income (25%) since the COVID-19 pandemic. Approximately one-third of the participants (34%) reported COVID-19 had an impact on their HIV care and treatment. Greater COVID-19 financial concerns (adjusted odds ratio [aOR] = 1.14, 95% CI: 1.02 to 1.27), mental health challenges (aOR = 1.38, 95% CI: 1.06 to 1.79), and partner emotional abuse (aOR = 2.62, 95% CI: 1.01 to 6.79) were associated with higher odds of negatively affected HIV care, respectively. The relationship between increased emotional partner abuse and negatively affected HIV care was mediated by greater COVID-19-related mental health challenges. CONCLUSIONS: FSW living with HIV in the Dominican Republic have been significantly affected by the COVID-19 pandemic. Targeted interventions that address structural (financial security and partner abuse) and psychosocial (mental health) factors are needed to sustain HIV outcomes and well-being.

Exploring peer navigation and support in the quality of HIV care experiences of female sex workers in the Dominican Republic.

BACKGROUND: Despite evidence on peer navigation's association with positive HIV outcomes, such as engagement in HIV care and antiretroviral therapy (ART) initiation, the mechanisms through which peer navigation may influence these outcomes have been less explored. The purpose of this study is to describe the role of peer navigation and support on enhancing the quality of HIV treatment and care services experienced by female sex workers (FSWs). METHODS: Survey data was derived from a quantitative cohort (n = 211) of FSWs living with HIV in the Dominican Republic and complemented with data from two rounds of in-depth interviews (IDIs) from a qualitative subsample (n = 20 per round). Descriptive statistics and multivariable logistic regressions were used to explore the association between peer navigation and relational aspects of care and overall satisfaction of the quality of HIV treatment and care. Thematic analysis was employed to code and synthesize textual data from IDIs. RESULTS: 41.2% of the participants reported having had contact with a peer navigator in the last 6 months. Qualitative data revealed that peer navigation and support was instrumental in assisting FSWs linkage to HIV care after diagnosis, elevating FSWs' ability to access more comprehensive clinical care facilities, and promoting agency by improving FSWs' skills to more strategically and effectively engage with the clinic environment and health care providers. Peer navigation was positively associated with experiencing more respectful treatment by clinic staff (AOR: 6.65, 95% CI: 2.32-19.02), and greater satisfaction with overall HIV care services (AOR: 2.57, 95% CI: 1.77-3.74). CONCLUSION: Promoting the full integration of peer navigation into healthcare structures is a strategic approach to enhance the quality of HIV care experienced by FSWs and improve their HIV-related outcomes.

"She is the one who knows": A qualitative exploration of oral and injectable PrEP as part of a community empowerment approach to HIV prevention among female sex workers in the Dominican Republic and Tanzania.

Despite documented interest among female sex workers (FSW), uptake of oral pre-exposure prophylaxis (PrEP) for HIV prevention has been low. Recent trials and regulatory approval of long-acting injectable (LAI) PrEP offer new hope for the potential of this biomedical intervention. We examined FSW's PrEP-related interest and preferences regarding both oral and LAI PrEP situating these dynamics within their specific social and occupational realities. We conducted this work using qualitative methods across two distinct contexts by conducting 40 in-depth interviews with FSW in Tanzania and the Dominican Republic. Textual data was coded using iterative thematic content analysis. Analytic summaries were developed and reviewed to identify recurring themes. We systematically organized themes within each country and then compared across settings. Women in both settings expressed strong interest in PrEP seeing it as an important option to protect themselves in their work. Most participants preferred LAI PrEP due to expectations of reduced stigma and concerns about daily pill adherence and side effects. Occupational factors such as alcohol use, overnight dates with clients, and fear of violence from clients were identified as barriers to daily oral PrEP. LAI PrEP was seen as having the potential to reduce stress related to oral PrEP. Women who preferred pills discussed fear of needles, skepticism about the injections, and others relayed that taking a daily pill would not be challenging for them. There was a pre-dominant sentiment that women know best whether they are better suited for oral or LAI PrEP. Participants stressed the importance of FSW understanding both options to ensure informed decision-making around PrEP and described community-led peer education as key to delivering trusted information. Community empowerment approaches led by FSW which address structural and psychosocial constraints and promote safe work environments may facilitate equitable access and uptake of PrEP among FSW across settings.

Acceptability and perceptions of HIV oral self-testing across settings: A comparative qualitative study among Dominican and Tanzanian female sex workers.

Rapid oral HIV self-tests (HIVST) have potential to increase the proportion of people who know their HIV status, especially among stigmatised populations. This study was embedded in two cohorts of female sex workers (FSW) in the Dominican Republic (DR) and Tanzania. Qualitative interviews with 40 FSW were conducted to explore perceived acceptability of HIVST. Interviews were analysed using inductive and deductive thematic coding. Emergent themes were organised by socio-ecological framework levels. FSW in both settings responded positively to the ease of use of HIVST but questioned test accuracy due to the use of saliva rather than blood. FSW in the DR had a more cautious response, while women in Tanzania had favourable perceptions expressing eagerness to use it. At the individual level, themes shaping participants' interest included autonomy, HIV risk perception, and emotional well-being for those with reactive test results, and self-efficacy. At the interpersonal level, privacy, confidentiality, sex work and HIV stigma and social support were salient. Structural level themes focused on health systems including linkages to HIV treatment, provider roles, and access (cost, travel, distribution). Understanding FSW's perceptions and acceptability of HIVST is essential to its integration into health systems and programmes using a community-driven approach.

Exploring antiretroviral therapy adherence, competing needs, and viral suppression among people living with HIV and food insecurity in the Dominican Republic.

Understanding factors related to suboptimal adherence to antiretroviral therapy (ART) and detectable viral load (VL), especially among vulnerable populations, is needed to improve HIV outcomes. The Caribbean is highly impacted by HIV and socioeconomic inequalities, but few studies have been conducted there to explore food insecurity among people with HIV and factors associated with viral suppression in this vulnerable population. Using baseline data from a pilot intervention trial among people living with HIV and food insecurity in the Dominican Republic, we examined psychosocial and behavioral factors associated with viral suppression, ART adherence, and competing needs. Among participants (n = 115), 61% had a detectable VL; the strongest factor associated with detectable VL was having missed taking ART in the last six months due to not having food (OR = 2.68, p = 0.02). Greater odds of reporting missed ART doses due to not having food were associated with severe food insecurity (OR = 4.60, p = 0.006), clinical depression (OR = 2.76, p = 0.018), Haitian background (OR = 6.62 p = 0.017), and internalized HIV stigma (OR = 1.09, p = 0.041), while lower odds were associated with social support (OR = 0.89, p = 0.03) and having health insurance (OR = 0.27, p = 0.017). Ensuring that people with HIV and food insecurity have food to take with their ART is essential for viral suppression.

Sequence and vector shapes vaccine induced antibody effector functions in HIV vaccine trials.

Despite the advent of long-acting anti-retroviral therapy able to control and prevent infection, a preventative vaccine remains a global priority for the elimination of HIV. The moderately protective RV144 vaccine trial suggested functional IgG1 and IgG3 antibodies were a potential correlate of protection, but the RV144-inspired HVTN702 validation trial failed to demonstrate efficacy despite inducing targeted levels of IgG1/IgG3. Alterations in inserts, and antigens, adjuvant, and regimen also resulted in vaccine induced target quantitative levels of the immune correlates, but drove qualitative changes to the humoral immune response, pointing to the urgent need to define the influence of vaccine strategies on shaping antibody quality, not just quantity. Thus, defining how distinct prime/boost approaches tune long-lived functional antibodies represents an important goal in vaccine development. Here, we compared vaccine responses in Phase I and II studies in humans utilizing various combinations of DNA/vector, vector/vector and DNA/protein HIV vaccines. We found that adenoviral vector immunization, compared to pox-viral vectors, resulted in the most potent IgG1 and IgG3 responses, linked to highly functional antibody activity, including assisting NK cell related functions. Minimal differences were observed in the durability of the functional humoral immune response across vaccine regimens, except for antibody dependent phagocytic function, which persisted for longer periods in the DNA/rAd5 and rAd35/rAd5 regimen, likely driven by higher IgG1 levels. Collectively, these findings suggest adenoviral vectors drive superior antibody quality and durability that could inform future clinical vaccine studies.

Disrupting the Systems: Opportunities to Enhance Methodological Approaches to Address Socio-Structural Determinants of HIV and End the Epidemic Through Effective Community Engagement.

A world without HIV is only possible by addressing the socio-structural determinants of health. Our understanding of socio-structural determinants is constantly changing, and parallel changes must occur with the methodologies used to explain the drivers of the HIV epidemic. We argue for the need to engage communities in the planning, implementation, and dissemination of research on the socio-structural determinants of HIV. Community engagement should cross-cut various types of research including rigorous measurement development of socio-structural determinants and novel analytic techniques to model their role in the trajectory of the epidemic and the impact of interventions. Considering the role of place, we recommend collaboration between scientists and communities in the interpretation of results from studies that map HIV-related behaviors and movement. As we collectively delve into historically oppressive systems with colonial antecedents, we must be ready to challenge these systems and replace them with collaborative models. The success of research-driven HIV policy and programming will best be evaluated with methodologies derived from the insights of the very individuals that these policies and programs aim to serve.

RESUMEN: Un mundo sin VIH es posible sólo si atendemos los determinantes socio-estructurales de la salud. Nuestra comprensión sobre determinantes socio-estructurales cambia constantemente y cambios similares deben ocurrir en las metodologías utilizadas para explicar los factores que rigen la epidemia del VIH. Argumentamos sobre la necesidad de involucrar las comunidades en la planificación, implementación y diseminación de investigaciones sobre los determinantes socio-estructurales del VIH. La participación comunitaria debe ser transversal en varios tipos de investigaciones, incluyendo el desarrollo riguroso de métricas sobre los determinantes socio-estructurales y técnicas noveles para la modelación de su rol en las trayectorias de la epidemia y el impacto de intervenciones. Considerando el rol que tiene el lugar físico, recomendamos la colaboración de científicos y comunidades en la interpretación de resultados de estudios que crean mapas de las conductas relacionadas al VIH y la movilidad de las personas. En la medida en que examinamos sistemas históricamente opresivos con antecedentes coloniales, debemos estar listos para retar estos sistemas y remplazarlos con modelos colaborativos. El logro de políticas y programas de VIH informados por la investigación sería evaluado mejor si se utilizan metodologías guiadas por el conocimiento de las personas a las cuales estas políticas y programas persiguen servir.

"I've Learned to Value Myself More": Piloting an Adapted Multilevel Intervention for Transgender Women Sex Workers Living with HIV in the Dominican Republic.

Purpose: Transgender (trans) women living with HIV experience suboptimal care and treatment outcomes. We adapted a multilevel intervention to improve HIV outcomes and overall well-being among trans women sex workers living with HIV. The intervention, called Abriendo Puertas (AP; Opening Doors), included: individual counseling, peer navigation, and community mobilization "open houses." The purpose of this article is to describe acceptability and initial outcomes of the adapted AP pilot and explore intervention experiences to inform recommendations for improvement. Methods: After an iterative adaptation process, we recruited 30 trans women sex workers living with HIV to participate in the pilot. We conducted baseline and endline (12-months) surveys to compare HIV care and treatment outcomes and qualitative interviews to assess intervention experiences with a subsample (n=20). Results: Intervention retention was high, with 86.7% of participants (n=26/30) completing both baseline and endline surveys. At endline, there was a significant increase in current anti-retroviral therapy (ART) use (70.0% to 84.6%, p<0.03) and positive, but not significant, trends in missed care appointments in the past 6 months (34.5% to 20.0%, p<0.39) and not having missed any ART doses in the past 4 days (85.7% to 95.5%, p<0.50). Intervention acceptability was high across all components: individual counseling (96.1%), peer navigation (80.8%), and open houses (84.6%). Participants emphasized that trust and being treated with respect allowed them to relax and improve their self-esteem. Limited trust and cohesion among trans women, however, limited more extensive engagement with peer navigation and community mobilization components. Conclusion: Future efforts to strengthen the AP intervention with trans women sex workers should continue to address emotional, instrumental, and informational support needs related to living with HIV through individual counseling, peer navigation, and open houses while also enhancing group-level activities to build trust and generate a collective commitment to promote the well-being of the community.
