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.

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.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.

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.

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.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.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.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.

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.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%: 1.01–1.07) y un tratamiento respetuoso (RMa: 2.17; IC del 95%: 1.09–4.32) 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%: 0.34–0.95) como la supresión viral (RMa: 0.59, IC del 95%: 0.41–0.85). 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%: 1.50–11.52) y la supresión viral (RMa: 2.75 para la comprensión del conteo de CD4; IC del 95%: 1.31–5.80). 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.

Globally, transgender (trans) women experience pervasive stigma, which contributes to health inequities across multiple mental health outcomes. While trans stigma has been associated with increased mental health challenges, less is known about how stigma related to sex work and HIV affect mental health. Social cohesion may ameliorate the negative health consequences of stigma, but little is known about how social cohesion is associated with mental health among trans women. Using cross-sectional survey data collected in 2019 among 100 trans women sex workers living with HIV in Santo Domingo, Dominican Republic, we examined associations between stigma (related to HIV, sex work, and trans identity), social cohesion, and depression and anxiety symptoms. In unadjusted models, enacted and internalized sex work stigma were associated with greater odds of depression and anxiety symptoms and social cohesion was associated with less depression and anxiety. Resisted sex work stigma, which captured acceptance of self and work, was associated with lower odds of depression and trans stigma was associated with increased anxiety. In adjusted models, internalized sex work stigma was associated with increased depression (aOR=1.19, p=0.018) and anxiety symptoms (aOR=1.12, p=0.021), while social cohesion was associated with reduced depression (OR=0.81, p=0.002) and anxiety symptoms (aOR=0.086, p=0.023). Findings indicate the need for interventions to focus on reducing internalized sex work stigma and promoting social cohesion to improve mental health among trans women. Additional research is needed to determine how to best measure the intersections between HIV, sex work, and trans stigma and their impact on mental health.

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.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.

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.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.

The purpose of this study was to characterize the social networks of female sex workers (FSWs) living with HIV in the Dominican Republic (DR) and to examine the association between daily drug use and network risk profile. The study employed a micro-longitudinal observational design using a 7-day mobile health (mHealth) daily diary to collect daily substance use behaviors and social network data was collected at study enrollment. A series of crude and adjusted modified log-Poisson repeated measures regression models with generalized estimating equations (GEE), clustering by individual with a compound symmetry working correlation structure were fit to estimate the relative risks and 95% confidence intervals. Controlling for individual level factors, findings revealed that FSWs with more network members who were drug users (≥ 3) and more network members who were sexual partners and also drugs users (≥ 2) were 8.89 (95% CI 2.62, 30.22) and 6.08 (95% CI 1.20, 30.92) times more likely to engage in daily drug use compared to women with small drug and sex and drug networks. Study findings demonstrate the role high risk networks have on risk behaviors. Results may be used to inform interventions that focus on modifying negative social ties, creating and/or improving existing positive support relationships, and integrating drug use harm reduction promotion within HIV treatment programs.El objetivo de este estudio era de caracterizar las redes sociales de las trabajadoras sexuales viviendo con VIH en la República Dominicana y examinar la asociación entre el uso diario de drogas y las características de la red de riesgo. El estudio utilizó un diseño observacional micro-longitudinal utilizando un diario móvil de 7 días para capturar los comportamientos diarios del uso de sustancias, y los datos de las redes sociales fue recolectado durante la inscripción al estudio. Una serie de modelos crudos y ajustados de regresión de log-Poisson con medidas repetidas y Ecuaciones de Estimación Generalizadas (EEG), agrupando por individuo con una estructura de correlación de simetría compuesta para estimar el riesgo relativo y los intervalos de confianza al 95%. Los hallazgos mostraron que las trabajadoras sexuales con mayor número de miembros de sus redes sociales que usaran drogas (3) y parejas sexuales que usaran drogas (2) fueron 8.89 (95% IC: 2.62, 30.33) y 6.08 (95% CI: 1.02, 30.92) veces más probables de participar en el consumo diario de drogas en comparación con las mujeres con pequeñas redes de consumo de drogas y sexo, controlando por factores a nivel individual. Los resultados del estudio demuestran el papel que las redes de alto riesgo tienen en los comportamientos de riesgo. Los resultados pueden ser utilizados para informar intervenciones que se enfoquen en el cambio de las relaciones negativas, creando o mejorando las relaciones de apoyo, e integrando la promoción de la reducción del uso de drogas dentro de los programas de tratamiento del VIH.

PURPOSE OF REVIEW: This review describes social determinants of HIV in two geographic and epidemic settings, the Dominican Republic (DR) and Tanzania, among female sex workers (FSW), their influence on HIV outcomes including 90-90-90 goals, and the development and impact of tailored, context driven, community empowerment-based responses in each setting. RECENT FINDINGS: Our review documents the significance of social determinants of HIV including sex work-related stigma, discrimination and violence and the impact of community empowerment-based approaches on HIV incidence in Tanzania and other HIV prevention, treatment and care outcomes, including care engagement and adherence, in the DR and Tanzania. SUMMARY: Community empowerment approaches where FSW drive the response to HIV and strategically engage partners to target socio-structural and environmental factors can have a demonstrable impact on HIV prevention, treatment and care outcomes. Such approaches can also support further gains towards reaching the 90-90-90 across geographies and types of epidemics.

Overall, adult men are less likely to seek and receive health care than women, but male circumcision for HIV prevention has been successful in engaging men in health services. The purpose of this paper is to examine the relationship between masculine norms and health care-seeking among men participating in a voluntary male medical circumcision (VMMC) programme in the Dominican Republic (DR). We employed a mixed methods approach integrating survey data collected 6-12 months post-circumcision (

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.

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

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.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.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.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.

Background A common approach for measuring place-based exposure is to use geographically-defined administrative boundaries and to link neighborhood characteristics at this level. This approach, however, may not be feasible in low-to middle-income countries where neighborhood-level data are limited or unavailable, and administrative boundaries are often unstandardized and not proportional to population size. Furthermore, such traditional approaches may not be appropriate for marginalized populations whose environments can be more difficult to study. In this paper, we describe two innovative and feasible methods to generate geospatial data to characterize and assess the role of risk environments on drug use among female sex workers living with HIV in the Dominican Republic. Methods Participatory geographic mapping and daily activity space travel diaries were employed. Results The methods presented in this study were feasible to implement, acceptable by study participants, and yielded rich geospatial data to analyze the impact of contextual factors on risk behaviors of female sex workers in a low-to middle-income country. Conclusion Participatory geographic mapping and activity space diaries are two alternative methods for collecting geospatial data among hard-to-reach populations in resource constrained settings. Moreover, the methods are interactive and educational, allowing study participants to take an active role in the data collection process and potentially allowing for a deeper understanding of place-based effects on health and behavior.

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. Trial registration: ClinicalTrials.gov NCT00801697, NCT00961883, NCT02207920, NCT00125970, NCT02852005)., Author summary Previous HIV-1 vaccine trials, including the RV144 efficacy trial that resulted in moderate protection from infection, showed the importance of non-neutralizing antibody responses and their contribution to protection against the virus. However, so far it is unclear how to specifically induce these potentially protective responses via vaccination and the question remains which prime/boost vaccine strategy is the most promising one. In this study, we directly compared the humoral immune response elicited by different heterologous HIV-1 prime/boost vaccine regimen utilizing different components such as DNA, pox- and adenovectors (rAd) and protein. We found that the combination of a DNA or rAd prime with a rAd boost resulted in strong IgG1 and IgG3 responses, which have been shown to be associated with reduced risk in RV144. Moreover, these regimens induced long-lived ADCP responses, an antibody driven functional response mediated by monocytes, that has been shown to be protective in non-human primate trials. In the light of the ongoing efficacy trial HVTN 705 which is utilizing an adenovirus prime, this data could give important input to analyze Fc-mediated functions and non-neutralizing antibody titers in future efficacy trials.

While HIV stigma has received significant attention, limited work has been conducted on the measurement of intersecting stigmas. We developed the Experiences of Sex Work Stigma (ESWS) scale in the Dominican Republic (DR) and Tanzania. We conducted in-depth interviews with 20 female sex workers (FSW) per country to identify scale domains followed by cognitive debriefing interviews to assess content validity. Items were administered in a survey to FSW in DR (n = 211) and Tanzania (n = 205). Factor analysis established four sex work stigma domains including: shame (internalized), dignity (resisted), silence (anticipated) and treatment (enacted). Reliability across domains ranged from 0.81 to 0.93. Using item response theory (IRT) we created context-specific domain scores accounting for differential item functioning between countries. ESWS domains were associated with internalized HIV stigma, depression, anxiety, sexual partner violence and social cohesion across contexts. The ESWS is the first reliable and valid scale to assess multiple domains of sex work stigma and can be used to examine the effects of this form of intersectional stigma on HIV-related outcomes across settings.

We examined the relationship between mindfulness, mental health and HIV outcomes among female sex workers (FSW) from the Dominican Republic (DR) (n = 201) and Tanzania (n = 208) using cross-sectional survey and biologic data. We employed stratified multivariate linear and logistic regression. Depression was associated with lower odds of ART adherence in the DR (AOR 0.25, 95% CI: 0.08-0.78) and of viral suppression in Tanzania (AOR 0.49, 95% CI: 0.24-0.97). In both countries, mindfulness was associated with lower odds of moderate to severe depression (AOR 0.82, 95% CI: 0.76-0.88 for the DR; AOR 0.85, 95% CI: 0.77-0.95 for Tanzania). In the DR, mindfulness was associated with lower odds of anxiety (AOR 0.83, 95% CI: 0.77-0.89), lower HIV stigma (β = - 0.28 per unit change, 95% CI: - 0.37 to - 0.19) and greater odds of viral suppression (AOR 1.09, 95% CI: 1.02-1.15). Findings demonstrate the potential of tailored mindfulness interventions to improve mental health and HIV outcomes among FSW.Examinamos la relación entre la atención plena, la salud mental y los resultados del VIH entre las trabajadoras sexuales (TRSX) de la República Dominicana (RD) (n = 201) y Tanzania (n = 208) utilizando una encuesta transversal y datos biológicos. Empleamos regresión lineal multivariada estratificada y regresión logística. La depresión se asoció con menores probabilidades de adherencia al terapia antiretroviral (TAR) en la República Dominicana (AOR 0.25, IC del 95%: 0.08–0.78) y de supresión viral en Tanzania (AOR 0.49, IC del 95%: 0.24–0.97). En ambos países, la atención plena se asoció con menores probabilidades de depresión moderada a grave (AOR 0.82, IC del 95%: 0.76–0.88 para la República Dominicana; AOR 0.85, IC del 95%: 0.77–0.95 para Tanzania). En la República Dominicana, la atención plena se asoció con menores probabilidades de ansiedad (AOR 0.83, IC del 95%: 0.77–0.89), menor estigma del VIH (β = − 0.28 por unidad de cambio, IC del 95%: − 0.37 to − 0.19) y mayores probabilidades de supresión viral (AOR 1.09, 95% CI: 1.02–1.15). Los hallazgos demuestran el potencial de las intervenciones de atención plena para mejorar la salud mental y los resultados del VIH entre las TRSX.

BackgroundLong-acting injectable antiretroviral therapy (LA ART) was found to be non-inferior to daily oral ART in Phase 3 clinical trials. LA ART may offer an important alternative for people living with HIV with challenges adhering to daily oral ART or preferences for non-pill-based regimens.MethodsUsing a mixed methods approach integrating survey, in-depth interview and biological data from female sex workers (FSW) living with HIV in Tanzania (N = 208) and the Dominican Republic (DR) (N = 201), we assessed factors associated with the potential likelihood of LA ART use if it were available. We conducted multivariate logistic regression and thematic content analysis.ResultsLikelihood of LA ART use was high with 84.92% of FSW from the DR and 92.27% of FSW from Tanzania reporting they would be "likely" or "very likely" to use LA ART if available (p = 0.02). In Tanzania better HIV-related patient-provider communication (AOR 4.58; 95% CI 1.90-11.05) and quality of HIV clinical care (AOR 3.68; 95% CI 1.05-12.86) were positively associated with the high likelihood of LA ART use. In the DR, easier clinic access was associated with a higher likelihood of LA ART use (AOR 3.04; 95% CI 1.41-6.56), as was greater monthly income from sex work (AOR 2.37; 95% CI 1.27-4.41). In both settings, years on ART was significantly associated with a strong likelihood of LA ART use (TZ: AOR 1.16 per year; 95% CI 1.00-1.34/DR: AOR 1.07 per year; 95% CI 1.00-1.14). Qualitative findings underscored enthusiasm for LA ART and reinforced its potential to address sex work-specific barriers to daily oral ART adherence including work-related schedules and substance use.ConclusionsWe found a high likelihood of LA ART use if available among FSW in two diverse settings and documented barriers to future uptake. Community-driven approaches which include tailored health education and improved patient-provider communication and quality of care, as well as strategies to facilitate appointment adherence are needed to optimize LA ART use among FSW.

Evidence indicates that social cohesion is a successful strategy to improve consistent condom use (CCU) among female sex workers. However, the individual and layered or combined effect that various types of overlapping stigmas may have on CCU between female sex workers living with HIV and their clients and steady partners has not been analyzed. Drawing on the Abriendo Puertas cohort of female sex workers living with HIV in the Dominican Republic, we used structural equation modeling to test the hypothesis that both HIV stigma and sex work stigma mediate the association between social cohesion and CCU and that they have a layered effect. The results indicated that HIV stigma mediated the association between social cohesion and CCU with clients and partners, while sex work-related stigma did not. There was no evidence of a layered HIV stigma and sex work stigma effect, which may be due to methodological limitations to handle highly correlated latent variables. Findings highlight the need to address internalized HIV stigma within the context of community-based approaches to enhance their HIV prevention impact. This will help to reduce the risk of HIV re-infection with a new distinct HIV viral strain, STI infection, and onward HIV transmission among female sex workers living with HIV.

We use data collected from in-depth interviews with men ( n = 30) in the Dominican Republic to explore how men’s concern about being perceived as masculine influences their interactions with their social networks and how those interactions drive men’s sexual behaviors and use of violence. Men’s sexual and violent behaviors were shaped by the need to compete with other men for social status. This sense of competition also generated fear of humiliation for failing to provide for their families, satisfy sexual partners, or being openly disrespected. In an effort to avoid humiliation within a specific social group, men adapted their behaviors to emphasize their masculinity. Additionally, men who were humiliated recouped their masculinity by perpetrating physical or emotional violence or finding new sexual partners. These findings emphasize the need for understanding these social dynamics to better understand men’s violent and sexual behaviors.

Female sex workers (FSWs) are disproportionately affected by HIV, but there is limited research on their HIV care experiences. This study explored the experiences of 44 FSWs living with HIV in Santo Domingo, Dominican Republic along the HIV care continuum using in-depth interviews and focus groups. Data were analysed through narrative and thematic analysis. Individual-level factors that facilitated engagement in HIV care were physical and mental health. At the interpersonal level, disclosure of HIV or sex work status and receipt of emotional and economic support were important influences on engagement. Yet, negative reactions to or lack of disclosure of these statuses compromised engagement, further highlighting the role of stigma and discrimination. At the environmental level, FSWs described considerable challenges with the health system including long waits and treatment stock-outs at their clinics, but were generally satisfied with HIV clinic staff. At the structural level, lack of economic resources complicated care and treatment adherence. Findings underscore the need for psychosocial and economic support tailored to the unique needs of FSWs to maximise the individual and public health benefits of HIV care.

Background Voluntary medical male circumcision (VMMC) is effective in decreasing the risk of HIV acquisition. As men resume sexual activity after circumcision, it will be important to study their satisfaction with the procedure, sexual pleasure and function, coital trauma, and risk compensation (RC), which can hamper or facilitate the long-term success of VMMC programs. Aim To assess men's satisfaction with VMMC, sexual pleasure and function, coital trauma, and RC after VMMC. Methods This is a cohort study of circumcised men who presented for follow-up 6 to 24 months after VMMC. Logarithmic binomial regression was performed to explore factors associated with any increase in the number of sex partners after VMMC as a measurement of RC. Main Outcome Measures (i) Men's satisfaction with their VMMC; (ii) sexual pleasure and function after VMMC; (iii) coital trauma; and (iv) RC. Results Of 454 circumcised men, 362 (80%) returned for a follow-up visit 6 to 24 months after VMMC. Almost all (98%) were satisfied with the outcome of their VMMC; most (95%) reported that their female partners were satisfied with their circumcision. Two thirds (67%) reported enjoying sex more after VMMC and most were very satisfied or somewhat satisfied (94%) with sexual intercourse after VMMC. Sexual function improved and reported sex-induced coital injuries decreased significantly in most men after VMMC. There was an increase in the proportion of men who reported at least two sexual partners after VMMC compared with baseline. In multivariate analysis, having sex with a woman they met the same day (adjusted relative risk = 1.7, 95% CI = 1.2–2.4) and having at least two sexual partners at baseline (adjusted relative risk = 0.5, 95% CI = 0.3–0.8) were associated with the outcome of any increase in the number of partners after VMMC. Clinical Implications VMMC can be offered to Dominican men for HIV prevention without adversely affecting sexual pleasure or function. The procedure substantially reduces coital trauma. Strengths & Limitations This is the first report of long-term overall satisfaction, sexual pleasure/function and sex behaviors in the context of VMMC outside of Africa. Limitations of the study included the reliance on self-reported sex behaviors, the lack of physiologic measurement of penile sensitivity and the lack of follow up data beyond 24 months, which precludes the assessment of longer term RC. Conclusion The study confirmed men's long-term satisfaction with the outcome of their VMMC. VMMC improved sexual pleasure and function for most men and significantly decreased coital injuries. There was mixed evidence of RC.

Background Health providers can play an important role in communication about pregnancy, particularly for women at increased risk for pregnancy complications, including female sex workers (FSWs) living with HIV. This study explored factors related to patient-provider communication about pregnancy among 253 FSWs living with HIV of reproductive age in Santo Domingo, Dominican Republic. Methods A cross-sectional design was employed including structured socio-behavioral surveys. Data were analyzed utilizing bivariate and multivariate logistic regression. Results Of the 253 FSWs living with HIV in this study, 95.7% had been pregnant at least once (median: 4; IQR: 3,6), 28.0% wanted more children and 36% reported a pregnancy after HIV diagnosis. Over half of participants (58.0%) reported having ever spoken to a health provider about pregnancy while living with HIV. Multivariate logistic regression found significant associations between having spoken to a health provider about HIV in pregnancy and a more positive perception of their provider (AOR: 2.0; 95% CI: 1.0, 2.5) and years since HIV diagnosis (AOR: 1.1; 95% CI: 1.0, 1.1). Participants were less likely to speak with a provider if they had a history of drug use (AOR: 0.4; 95% CI: 0.2, 0.9) or current alcohol use (AOR: 0.5; 95% CI: 0.3, 0.9). Conclusion Findings highlight the importance of non-judgmental and tailored provider-initiated conversations surrounding pregnancy. Future research is needed to better understand how and when pregnancy communication is initiated, as well as the content of clinical care conversations, to address the reproductive health of FSWs living with HIV.

The purpose of this study was to explore the daily activity spaces of female sex workers living with HIV in the Dominican Republic and assess the relationship between activity path and location-based risk exposure measures and daily drug use. The study employed a micro-longitudinal observational study design using an innovative 7-day travel diary to capture daily activity routes and a 7-day mobile health (mHealth) daily diary to collect daily substance use behaviors among 51 female sex workers. To estimate between-subject variability, a series of crude and adjusted modified log-Poisson repeated measures regression models with generalized estimating equations, clustering by individual with a compound symmetry working correlation structure were fit to estimate the relative risks and 95% confidence intervals. Controlling for individual level factors, findings showed that female sex workers exposed to a higher number of risk outlets (e.g., liquor stores, bars, hotels, nightclubs, brothels, etc.) within 200 and 100-meters of sex work locations were at an increased risk of daily drug use (RRadj: 1.03, 95%CI: 1.01, 1.05, RRadj: 1.05, 95%CI: 1.01, 1.09). No association was detected between activity path exposure and daily drug use. These findings illustrate the importance of moving beyond static residential neighborhood boundaries for measuring risk exposures and highlight the significant role that daily work environments have on drug harms among a highly stigmatized and vulnerable population.

Quantitative analyses exploring the relationship between masculinities and men's sexual risk behaviors have most commonly used one dimension of masculinities: men's gender ideology. Examining other dimensions may enhance our understanding of and ability to intervene upon this relationship. In this article, we examined the association between Gender Role Conflict/Stress (GRC/S)–men's concern about demonstrating masculine characteristics–and three different sexual risk behaviors (having two or more sex partners in the last 30 days; never/inconsistent condom use with non-steady partners; and drinking alcohol at last sex) among a sample of heterosexual men in the Dominican Republic who were participating in an HIV prevention intervention (n = 293). The GRC/S scale we used was adapted for this specific cultural context and has 17 items (α = 0.75). We used logistic regression to assess the relationship between GRC/S and each sexual behavior, controlling for sociodemographic characteristics. In adjusted models, a higher GRC/S score was significantly associated with increased odds of having two or more sex partners in the past 30 days (AOR: 1.33, 95% CI: 1.01-1.74), never/inconsistent condom use with non-steady partners (AOR: 1.45, 95% CI: 1.04-2.01), and drinking alcohol at last sex (AOR: 1.56, 95% CI: 1.13-2.17). These results highlight the importance of expanding beyond gender ideology to understanding the influence of GRC/S on men's sexual risk behaviors. Interventions should address men's concern about demonstrating masculine characteristics to reduce the social and internalized pressure men feel to engage in sexual risk behaviors.

Female sex workers (FSW) are disproportionately affected by HIV. Yet, few interventions address the needs of FSW living with HIV. We developed a multi-level intervention, Abriendo Puertas (Opening Doors), and assessed its feasibility and effectiveness among a cohort of 250 FSW living with HIV in the Dominican Republic. We conducted socio-behavioral surveys and sexually transmitted infection and viral load testing at baseline and 10-month follow-up. We assessed changes in protected sex and adherence to antiretroviral therapy (ART) with logistic regression using generalized estimating equations. Significant pre-post intervention changes were documented for adherence (72-89 %; p

ObjectiveFemale sex workers (FSW) have increased risk of HIV infection. Antiretroviral treatment (ART) can improve HIV outcomes and prevent HIV transmission. We analyzed antiretroviral (ARV) drug use and HIV drug resistance among HIV-positive FSW in the Dominican Republic and Tanzania.MethodsPlasma samples collected at study entry with viral loads >1,000 copies/mL were tested for ARV drugs and HIV drug resistance. ARV drug testing was performed using a qualitative assay that detects 22 ARV drugs in five classes. HIV genotyping was performed using the ViroSeq HIV-1 Genotyping System. Phylogenetic analyses were performed to determine HIV subtype and assess transmission clusters.ResultsAmong 410 FSW, 144 (35.1%) had viral loads >1,000 copies/mL (DR: n = 50; Tanzania: n = 94). ARV drugs were detected in 36 (25.0%) of 144 samples. HIV genotyping results were obtained for 138 (95.8%) cases. No transmission clusters were observed in either country. HIV drug resistance was detected in 54 (39.1%) of 138 samples (31/35 [88.6%] with drugs detected; 23/103 [22.3%] without drugs detected); 29/138 (21.0%) had multi-class resistance (MCR). None with MCR had integrase strand transfer inhibitor resistance. In eight cases, one or more ARV drug was detected without corresponding resistance mutations; those women were at risk of acquiring additional drug resistance. Using multivariate logistic regression, resistance was associated with ARV drug detection (pConclusionsIn this cohort, many women were on ART, but were not virally suppressed. High levels of HIV drug resistance, including MCR, were observed. Resistance was associated with detection of ARV drugs, self-report of ART with full or partial adherence, and duration of HIV infection. These findings highlight the need for better HIV care among FSW to improve their health, reduce HIV drug resistance, and decrease risk of transmission to others.

Importance Chikungunya virus (CHIKV) is a mosquito-borneAlphavirusprevalent worldwide. There are currently no licensed vaccines or therapies. Objective To evaluate the safety and tolerability of an investigational CHIKV virus–like particle (VLP) vaccine in endemic regions. Design, Setting, and Participants This was a randomized, placebo-controlled, double-blind, phase 2 clinical trial to assess the vaccine VRC-CHKVLP059-00-VP (CHIKV VLP). The trial was conducted at 6 outpatient clinical research sites located in Haiti, Dominican Republic, Martinique, Guadeloupe, and Puerto Rico. A total of 400 healthy adults aged 18 through 60 years were enrolled after meeting eligibility criteria. The first study enrollment occurred on November 18, 2015; the final study visit, March 6, 2018. Interventions Participants were randomized 1:1 to receive 2 intramuscular injections 28 days apart (20 µg, n = 201) or placebo (n = 199) and were followed up for 72 weeks. Main Outcomes and Measures The primary outcome was the safety (laboratory parameters, adverse events, and CHIKV infection) and tolerability (local and systemic reactogenicity) of the vaccine, and the secondary outcome was immune response by neutralization assay 4 weeks after second vaccination. Results Of the 400 randomized participants (mean age, 35 years; 199 [50%] women), 393 (98%) completed the primary safety analysis. All injections were well tolerated. Of the 16 serious adverse events unrelated to the study drugs, 4 (25%) occurred among 4 patients in the vaccine group and 12 (75%) occurred among 11 patients in the placebo group. Of the 16 mild to moderate unsolicited adverse events that were potentially related to the drug, 12 (75%) occurred among 8 patients in the vaccine group and 4 (25%) occurred among 3 patients in the placebo group. All potentially related adverse events resolved without clinical sequelae. At baseline, there was no significant difference between the effective concentration (EC50)—which is the dilution of sera that inhibits 50% infection in viral neutralization assay—geometric mean titers (GMTs) of neutralizing antibodies of the vaccine group (46; 95% CI, 34-63) and the placebo group (43; 95% CI, 32-57). Eight weeks following the first administration, the EC50 GMT in the vaccine group was 2005 (95% CI, 1680-2392) vs 43 (95% CI, 32-58;P Conclusions and Relevance Among healthy adults in a chikungunya endemic population, a virus-like particle vaccine compared with placebo demonstrated safety and tolerability. Phase 3 trials are needed to assess clinical efficacy. Trial Registration ClinicalTrials.gov Identifier:NCT02562482
