Mobility paradoxes: disruptors, benefits, and agency among mobile female sex workers living with HIV in the Dominican Republic and Tanzania.

Background: Mobility is a key social determinant of health for female sex workers (FSWs). While extant research has focused on the adverse effects of mobility for FSWs, there are very few studies that have examined the multiple ways in which mobility may impact the lives of these mobile women from their perspective. This qualitative study aims to fill this gap by exploring how mobility impacts the lives, livelihoods, and HIV care and treatment from the perspectives of women living with HIV in two epidemic settings, the Dominican Republic and Tanzania.

Longitudinal analysis of the role of mindfulness on HIV stigma, depression, substance use and HIV outcomes among female sex workers living with HIV in the Dominican Republic.

Female sex workers (FSW) living with HIV experience greater depression and worse HIV outcomes than people living with HIV (PLHIV) overall. Mindfulness is related to lower depression and higher ART adherence in PLHIV. Few studies have assessed these relationships among FSW, especially longitudinally.

Family rejection, acceptance, support and health among transgender women sex workers living with HIV in Santo Domingo, Dominican Republic.

Background: Rejection from parents can lead transgender (trans) youth and young adults to experience poor health outcomes, while parental and sibling acceptance and support can be protective against poor health outcomes. The role of family in adult trans women's lives has been minimally investigated.

Aim: This study aimed to explore experiences of familial rejection, acceptance, and support in the lives of trans women sex workers living with HIV in the Dominican Republic.

Comparing Stigma and HIV Outcomes Between Transgender and Cisgender Women Sex Workers Living with HIV in the Dominican Republic.

Purpose: Using an intersectionality framework, we compared stigma and HIV care and treatment outcomes across transgender and cisgender women sex workers living with HIV in the Dominican Republic (DR).

Methods: In 2018-2019, data were collected in Santo Domingo, DR, using interviewer-administered surveys among 211 cisgender women and 100 transgender women. We used -tests and chi-square tests to examine differences in sex work stigma, HIV stigma, and HIV care and treatment.

"You know that we travel a lot": Mobility narratives among female sex workers living with HIV in Tanzania and the Dominican Republic.

Female sex workers (FSW) are highly mobile, which may result in reduced access to and use of health services and increased risk for poor health outcomes, particularly for those living with HIV. Mobility includes spatial, temporal, and social elements that are not fully captured by quantitative measures. We conducted two rounds of in-depth interviews with FSW living with HIV in Iringa, Tanzania (n = 20), and Santo Domingo, Dominican Republic (n = 20), to describe mobility experiences and compare mobility narratives across settings.

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.

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).

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 (trichomoniasis), (syphilis), HIV, hepatitis B and C, and (HPV) among at-risk populations between 2015 and 2018.

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.

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.

"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.

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.

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.

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.

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.

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.

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.

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).

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.

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.

Stigma, Social Cohesion, and Mental Health Among Transgender Women Sex Workers Living with HIV in the Dominican Republic.

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.

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.
