RESUMO

Host metabolic dysregulation, especially in tryptophan metabolism, is intricately linked to COVID-19 severity and its post-acute sequelae (Long COVID). People living with HIV (PLWH) experience similar metabolic dysregulation and face an increased risk of developing Long COVID. However, whether pre-existing HIV-associated metabolic dysregulations contribute in predisposing PLWH to severe COVID-19 outcomes remains underexplored. Analyzing pre-pandemic samples from PLWH with documented post-infection outcomes, we found specific metabolic alterations, including increased tryptophan catabolism, predicting an elevated risk of severe COVID-19 and the incidence of Long COVID. These alterations warrant further investigation for their potential prognostic and mechanistic significance in determining COVID-19 complications.

RESUMO

Among 103 reproductive-aged women with HIV in the U.S. South surveyed post-approval of long-acting injectable (LAI) cabotegravir/rilpivirine, nearly two-thirds reported willingness to try LAI antiretroviral therapy (ART). Most expressed preference for LAI over daily oral ART and had minimal concerns over potential LAI-ART use impacting reproductive health.

RESUMO

INTRODUCTION: This study used an unsupervised machine learning algorithm, sidClustering and random forests, to identify clusters of risk behaviors of Bacterial Vaginosis (BV), the most common cause of abnormal vaginal discharge linked to STI and HIV acquisition.  METHODS: Participants were 391 cisgender women in Miami, Florida, with a mean of 30.8 (SD = 7.81) years of age; 41.7% identified as Hispanic; 41.7% as Black and 44.8% as White. Participants completed measures of demographics, risk behaviors [sexual, medical, and reproductive history, substance use, and intravaginal practices (IVP)], and underwent collection of vaginal samples; 135 behavioral variables were analyzed. BV was diagnosed using Nugent criteria. RESULTS: We identified four clusters, and variables were ranked by importance in distinguishing clusters: Cluster 1: nulliparous women who engaged in IVPs to clean themselves and please sexual partners, and used substances frequently [n = 118 (30.2%)]; Cluster 2: primiparous women who engaged in IVPs using vaginal douches to clean themselves (n = 112 (28.6%)]; Cluster 3: primiparous women who did not use IVPs or substances [n = 87 (22.3%)]; and Cluster 4: nulliparous women who did not use IVPs but used substances [n = 74 (18.9%)]. Clusters were related to BV (p < 0.001). Cluster 2, the cluster of women who used vaginal douches as IVPs, had the highest prevalence of BV (52.7%). CONCLUSIONS: Machine learning methods may be particularly useful in identifying specific clusters of high-risk behaviors, in developing interventions intended to reduce BV and IVP, and ultimately in reducing the risk of HIV infection among women.

RESUMO

BACKGROUND: Direct-acting antiviral (DAA) therapy for hepatitis C virus (HCV) is well tolerated, cost-effective, and yields high sustained virologic response rates, yet it has remained financially inaccessible to many patients. METHODS: Participants of the Women's Interagency HIV Study (an observational US cohort) with human immunodeficiency virus (HIV) and HCV (RNA+) reporting no prior hepatitis C treatment were followed for DAA initiation (2015-2019). We estimated risk ratios (RRs) of the relationship between time-varying health insurance status and DAA initiation, adjusting for confounders with stabilized inverse probability weights. We also estimated weighted cumulative incidences of DAA initiation by health insurance status. RESULTS: A total of 139 women (74% Black) were included; at baseline, the median age was 55 years and 86% were insured. Most had annual household incomes ≤$18 000 (85%); advanced liver fibrosis (21%), alcohol use (45%), and recreational drug use (35%) were common. Across 439 subsequent semiannual visits, 88 women (63%) reported DAA initiation. Compared with no health insurance, health insurance increased the likelihood of reporting DAA initiation at a given visit (RR, 4.94; 95% confidence limit [CL], 1.92 to 12.8). At 2 years, the weighted cumulative incidence of DAA initiation was higher among the insured (51.2%; 95% CL, 43.3% to 60.6%) than the uninsured (3.5%; 95% CL, 0.8% to 14.6%). CONCLUSIONS: Accounting for clinical, behavioral, and sociodemographic factors over time, health insurance had a substantial positive effect on DAA initiation. Interventions to increase insurance coverage should be prioritized to increase HCV curative therapy uptake for persons with HIV.

RESUMO

BACKGROUND: Estrogen-based hormone therapy (HT) may have beneficial cardiovascular effects when initiated in early menopause. This has not been examined in women with human immunodeficiency virus (HIV), who have heightened immune activation and cardiovascular risks. METHODS: Among 609 postmenopausal women (1234 person-visits) in the Women's Interagency HIV Study, we examined the relationship of ever HT use (oral, patch, or vaginal) with subclinical atherosclerosis: carotid artery intima-media thickness (CIMT), distensibility, and plaque assessed via repeated B-mode ultrasound imaging (2004-2013). We also examined associations of HT with cross-sectional biomarkers of immune activation and D-dimer. Statistical models were adjusted for sociodemographic, behavioral, and cardiometabolic factors. RESULTS: Women (mean age, 51 years; 80% HIV positive) who ever used HT at baseline were older, and more likely to be non-Hispanic White and report higher income, than never-users. Women who ever used HT had 43% lower prevalence of plaque (prevalence ratio, 0.57 [95% confidence interval {CI}, .40-.80]; P < .01), 2.51 µm less progression of CIMT per year (95% CI, -4.60, to -.41; P = .02), and marginally lower incidence of plaque over approximately 7 years (risk ratio, 0.38 [95% CI, .14-1.03; P = .06), compared with never-users, adjusting for covariates; ever HT use was not associated with distensibility. These findings were similar for women with and without HIV. Ever HT use was associated with lower serum D-dimer, but not with biomarkers of immune activation after covariate adjustment. CONCLUSIONS: HT may confer a subclinical cardiovascular benefit in women with HIV. These results begin to fill a knowledge gap in menopausal care for women with HIV, in whom uptake of HT is very low.

RESUMO

Intravaginal practices (IVPs) refer to placing items (e.g., water, soap, commercial douches, fingers, rags) inside the vagina. IVPs have been shown to contribute to the development of bacterial vaginosis (BV) and may increase sexually transmitted infections and HIV risk. We developed the Intravaginal Practices Questionnaire (IVQ). The purpose of this study was to validate the IVQ, with the goal of establishing a consistent method of assessing IVP across studies. Women enrolled in this study (n = 180) were on average 30 years of age (SD = 8.32). Half (54%) identified as non-Hispanic, and 45% identified as Black; 41% reported lifetime IVP. Past month IVP use included commercial douches (9%), water (35%), fingers (41%), soap (21%), cloths/rags/wipes (10%), and vinegar (3%), which were placed in the vagina. No women used yogurt or herbs. An exploratory factor analysis indicated that a single-factor structure best explained the underlying constructs in participant responses in six endorsed items assessing commercial douches, water, fingers, soap, clothes/rags/ wipes, and vinegar use, suggesting that a common factor underlies these behaviors. All factor loadings were > 0.496. Cronbach's α was 0.99, suggesting that the reliability of the scale was excellent. Lastly, a total IVQ score was related to BV diagnosis (p = .007) as well as self-reported symptoms of BV (p = .034). Results illustrate that the IVQ has adequate psychometric properties. This tool may be used by public health experts and clinicians to identify IVPs that may potentially increase HIV risk.

RESUMO

BACKGROUND: Persistent immune activation due to gut barrier dysfunction is a suspected cause of morbidity in HIV, but the impact of menopause on this pathway is unknown. METHODS: In 350 women with HIV from the Women's Interagency HIV Study, plasma biomarkers of gut barrier dysfunction (intestinal fatty acid binding protein; IFAB), innate immune activation (soluble CD14 and CD163; sCD14, sCD163), and systemic inflammation (interleukin-6 and tumor necrosis factor receptor 1; IL-6, TNFR1) were measured at 674 person-visits spanning ≤2 years. RESULTS: Menopause (post- vs premenopausal status) was associated with higher plasma sCD14 and sCD163 in linear mixed-effects regression adjusting for age and other covariates (ß = 161.89 ng/mL; 95% confidence interval [CI], 18.37-305.41 and 65.48 ng/mL, 95% CI, 6.64-124.33, respectively); but not with plasma IFAB, IL-6, or TNFR1. In piece-wise linear mixed-effects regression of biomarkers on years before/after the final menstrual period, sCD14 increased during the menopausal transition by 250.71 ng/mL per year (95% CI, 16.63-484.79; P = .04), but not in premenopausal or postmenopausal periods. CONCLUSIONS: In women with HIV, menopause may increase innate immune activation, but data did not support an influence on the gut barrier or inflammation. Clinical implications of immune activation during menopausal transition warrant further investigation.

RESUMO

Despite the efficacy of antiretroviral-based pre-exposure prophylactics (PrEP) in men who have sex with men, studies in women have produced widely varying outcomes. Recent evidence demonstrates that vaginal microbial communities are associated with increased HIV acquisition risk and may impact PrEP efficacy. Here, we investigate the mechanisms underlying how vaginal bacteria alter PrEP drug levels and impact HIV infection rates ex vivo. Using cervicovaginal lavages (CVLs) from women with or without bacterial vaginosis (BV), we identified microbial metabolism of PrEP drugs in BV samples through LC-MS/MS analysis of soluble drug levels and metabolite formation in dual T-cell cultures. CVL samples were assessed for microbiome analysis using sequencing of bacterial 16S rRNA genes. We also observed non-Lactobacillus bacteria that are associated with BV may potentially impact PrEP efficacy through increased HIV infection rates in co-cultures containing Lactobacillus or BV bacteria, PrEP drugs, CEM-GFP cells, and HIV-1LAI virus. Finally, we used these data to develop a novel predictive mathematical simulation modeling system to predict these drug interactions for future trials. These studies demonstrate how dysbiotic vaginal microbiota may impact PrEP drugs and provides evidence linking vaginal bacteria to PrEP efficacy in women.

RESUMO

Objectives. To examine the effects of within-neighborhood and neighboring characteristics on discrimination, stigma, mental health, and HIV outcomes among Black women living with HIV (BWLWH). Methods. A total of 151 BWLWH in a southeastern US city provided baseline data (October 2019‒January 2020) on experienced microaggressions and discrimination (race-, gender-, sexual orientation-, or HIV-related), mental health (e.g., depression, posttraumatic stress disorder), and HIV outcomes (e.g., viral load, antiretroviral therapy adherence). Neighborhood characteristics by census tract were gathered from the American Community Survey and the National Center for Charitable Statistics. Spatial econometrics guided the identification strategy, and we used the maximum likelihood technique to estimate relationships between a number of predictors and outcomes. Results. Within-neighborhood and neighboring characteristics (employment, education, crime, income, number of religious organizations, and low-income housing) were significantly related to intersectional stigma, discrimination, mental health, HIV viral load, and medication adherence. Conclusions. Policy, research, and interventions for BWLWH need to address the role of neighborhood characteristics to improve quality of life and HIV outcomes.

RESUMO

We evaluated the psychometric properties of a modified version of the Vaccine Hesitancy Scale (VHS) among people with HIV (PWH) for COVID-19 vaccination in a cross-sectional study in the US. Self-report data from an online questionnaire were collected from a sample of N = 175 PWH. Participants were surveyed in English or Spanish regarding attitudes towards COVID-19 vaccination using the adapted VHS. Participants were on average 51.55 years of age (SD = 13.90) 55% were women. The reliability of the scale was acceptable (α = 0.72). An exploratory factor analysis showed that "Lack of confidence" and "Risks" explained 45.55% and 12.31% of the variance. Related items showed expected associations with these factors, supporting construct validity. Results illustrate that the modified VHS for COVID-19 vaccination has adequate psychometric properties. We replicated the original factor structure of the VHS and demonstrated adequate internal consistency and construct validity. Validated tools are essential to guide vaccination policy and campaigns towards populations at risk.


RESUMEN: En este estudio transversal, evaluamos las propiedades psicométricas de la Escala de Reticencia a la Vacunación (VHS, por sus siglas en inglés) para la vacuna contra el COVID-19 en personas con VIH (PCV) en los EE. UU. Los participantes (N = 175) respondieron a una encuesta en línea en inglés o en español, sobre las actitudes hacia la vacuna contra el COVID-19 utilizando una version adaptada de la VHS. La edad promedio de los participantes fue de 51,55 años (DE = 13,90;) y 55% eran mujeres. La fiabilidad de la escala fue aceptable (α = 0,72). Un análisis factorial exploratorio mostró que la "falta de confianza" y los "riesgos" explicaron el 45,55% y el 12,31% de la varianza. Los elementos relacionados mostraron asociaciones esperadas con dichos factores, apoyando la validez de la VHS adaptada para esta población. Los resultados ilustran que la VHS modificada para la vacuna contra el COVID-19 tiene propiedades psicométricas adecuadas. Replicamos la estructura factorial original de la VHS y demostramos una adecuada validez y consistencia interna. La validación de instrumentos de recolección de datos es esencial para orientar las políticas y campañas de vacunación para poblaciones en riesgo, tal como PCV.

RESUMO

Although prior research has examined associations between blood pressure (BP), depression, and suicidal ideation, few studies have examined this in high-risk populations such as pregnant women with HIV (WHIV). The current study examined the association of BP with depression and suicidal ideation among pregnant WHIV (n = 217) in rural South Africa. BP data (measured ≤ 1 month before the study visit) was extracted from medical records. Depressive symptomatology and suicidal ideation were assessed using the Edinburgh Postnatal Depression Scale. Diastolic BP was positively associated with both suicidal ideation and depressive symptomatology, even after controlling for demographic variables, gestational age, and intimate partner violence. These findings suggest that WHIV with elevated BP may be at greater risk for antenatal depression and suicidal ideation. Future research should utilize longitudinal designs to examine potential mechanisms and the directionality of the relationship, as well as other contributing factors.


RESUMEN: Aunque investigaciones anteriores han examinado las asociaciones entre la presión arterial (PA), depresión e ideación suicida, pocos estudios han examinado esto en poblaciones de alto riesgo, como las mujeres embarazadas con VIH. El estudio actual examinó la asociación de la PA con la depresión y la ideación suicida entre mujeres embarazadas con VIH (n = 217) en zonas rurales de Sudáfrica. Los datos de PA (medidos ≤ 1 mes antes de la visita del estudio) se extrajeron de los registros médicos. La sintomatología depresiva y la ideación suicida se evaluaron mediante la Escala de depresión posnatal de Edimburgo. La PA diastólica se asoció positivamente tanto con la ideación suicida como con la sintomatología depresiva, incluso después de controlar variables demográficas, edad gestacional y violencia de la pareja íntima. Estos hallazgos sugieren que mujeres embarazadas con VIH con PA elevada puede tener un mayor riesgo de depresión prenatal e ideación suicida. Las investigaciones futuras deberían aprovechar diseños longitudinales para examinar los posibles mecanismos y la direccionalidad de la relación, así como otros factores contribuyentes.

RESUMO

Bacterial vaginosis (BV) is the most common genital infection in women and is associated with an increased risk of sexually transmitted infections and HIV. This study uses a syndemic approach to evaluate factors associated with BV. Non-pregnant, HIV-negative, sexually active, cis-gender women aged 18-45 years living in Miami, Florida were recruited from Nov.2018- Jun.2021. Participants completed a sociodemographic and behavioral questionnaire along with gynecological examinations. BV was diagnosed by Amsel criteria and confirmed by a Nugent score ≥ 4. A syndemic score was calculated as the sum of factors associated with BV. The association between syndemic score and BV was assessed using logistic regression. Of 166 women included, 60.2% had BV. Race, ethnicity, education, vaginal sex, recent cannabis use, and reasons for intravaginal practices were included in the syndemic score. Higher odds of BV were found in women with a score of ≥ 3 compared to women with a score of 0/1. A higher syndemic score was associated with increased odds of having BV. Multilevel interventions to decrease BV are needed to decrease women's risk of acquiring HIV.


RESUMEN: La vaginosis bacteriana (VB) es la infección genital más común en mujeres y está asociada con un mayor riesgo de enfermedades de transmisión sexual (ETS) y de VIH. Este estudio utilizó un enfoque sindémico para evaluar factores asociados con VB. Entre noviembre del 2018 y junio del 2021, se reclutaron mujeres cisgénero de entre 18­45 años, que no estuvieran embarazadas, que fueran VIH negativas y sexualmente activas, y que vivieran en Miami, Florida. Las participantes completaron un cuestionario sociodemográfico y de comportamiento junto con un examen ginecológico. Se diagnosticó VB empleando los criterios de Amsel y se confirmó empleando el criterio de Nugent con una puntuación ≥ 4. La puntuación sindémica fue calculada como la suma de factores asociados con VB utilizando. La asociación entre la puntuación sindémica con VB se evaluó mediate una regresión logística. De 166 mujeres incluidas, 60.2% fueron diagnosticadas con VB. Los factores incluidos en la puntuación sindémica fueron la raza, etnia, educación, sexo vaginal, consumo reciente de cannabis, y el uso de prácticas intravaginales. Se encontraron mayores probabilidades de VB en mujeres con una puntuación ≥ 3 en comparación con aquellas con una puntuación de 0/1. Una puntuación sindémica alta se asoció con una mayor probabilidad de tener VB. Son necesarias intervenciones multinivel para disminuir la VB y disminuir el riesgo de que las mujeres contraigan ETS y VIH.

RESUMO

BACKGROUND: Transgender women (TGW) consistently show lower adherence to antiretroviral treatment (ART), than cisgender people (CP) living with HIV. This study examined sociodemographic and psychosocial factors associated with gender identity among individuals disengaged from HIV care in Argentina. METHODS: Data for this study was obtained at baseline from the Conexiones y Opciones Positivas en la Argentina 2 (COPA2) study. Forty-one TGW and 360 CP (177 male, 183 female) disengaged from HIV care completed questionnaires assessing sociodemographic information, severity of depressive symptoms, substance and alcohol use, patient-provider relationship quality, self-efficacy, ART adherence motivation, self-reported adherence, and treatment-related factors. Analyses included chi-square tests exploring the association between categorical variables and gender identity, and ANCOVAs comparing groups controlling for age. RESULTS: Being a TGW was associated with having only public health insurance; substance use, particularly cocaine; substance-related problems; and hazardous drinking. TGW showed more negative consequences related to substance use, more hazardous alcohol use, lower patient-provider relationship quality, and lower self-reported adherence, than CP. CONCLUSIONS: Harm reduction should be a key component in HIV care for TGW to address substance use. Health care teams should receive formal training in patient-provider communication skills and trans-specific competencies to enhance TGW's adherence and retention. Public policies to address structural factors that negatively affect TGW's adherence to ART are also needed.

RESUMO

In 2019, the National Institutes of Health combined the Multicenter AIDS Cohort Study (MACS) and the Women's Interagency HIV Study (WIHS) into the MACS/WIHS Combined Cohort Study (MWCCS). In this paper, participants who made a study visit during October 2018-September 2019 (targeted for MWCCS enrollment) are described by human immunodeficiency virus (HIV) serostatus and compared with people living with HIV (PLWH) in the United States. Participants include 2,115 women and 1,901 men with a median age of 56 years (interquartile range, 48-63); 62% are PLWH. Study sites encompass the South (18%), the Mid-Atlantic/Northeast (45%), the West Coast (22%), and the Midwest (15%). Participant race/ethnicity approximates that of PLWH throughout the United States. Longitudinal data and specimens collected for 35 years (men) and 25 years (women) were combined. Differences in data collection and coding were reviewed, and key risk factor and comorbidity data were harmonized. For example, recent use of alcohol (62%) and tobacco (28%) are common, as are dyslipidemia (64%), hypertension (56%), obesity (42%), mildly or severely impaired daily activities (31%), depressive symptoms (28%), and diabetes (22%). The MWCCS repository includes serum, plasma, peripheral blood mononuclear cells, cell pellets, urine, cervicovaginal lavage samples, oral samples, B-cell lines, stool, and semen specimens. Demographic differences between the MACS and WIHS can confound analyses by sex. The merged MWCCS is both an ongoing observational cohort study and a valuable resource for harmonized longitudinal data and specimens for HIV-related research.

RESUMO

The COVID-19 pandemic poses a risk to mental health and may disproportionately affect people living with HIV (PLWH). This study examined the interaction of social support and resilient coping in predicting depressive symptoms among PLWH. PLWH residing in Buenos Aires, Argentina and in Miami, Florida (US) were asked to complete an anonymous survey on the impact of COVID-19. Statistical analysis included ordinary least squares regression. A total of 1,554 participants were included. Mean age was 47.30 years; 63.70% were men. A test of three-way interaction of social support × resilient coping × study site indicated differences by site (b = -0.63, p = 0.04, 95%CI [-1.24, -0.02]). In Argentina, higher levels of social support and resilient coping were associated with lower depressive symptoms. Lower levels of social support and resilient coping were associated with higher depressive symptoms. The impact of COVID-19 on mental health illustrates the need for developing innovative strategies to support resilience and to enhance coping with stress and adversity among PLWH.


RESUMEN: La pandemia de COVID-19 presenta riesgos importantes para la salud mental y puede afectar desproporcionadamente a personas con VIH. Este estudio examinó el efecto entre el apoyo social y la resiliencia para afrontar situaciones difíciles en predecir síntomas depresivos en personas con VIH. Personas con VIH residentes de Buenos Aires (Argentina) y Miami, Florida (EE.UU) completaron una encuesta anónima sobre el impacto del COVID-19. El análisis estadístico incluyó un modelo clásico de regresión lineal con mínimos cuadrados ordinarios. Se incluyeron 1554 participantes. La edad promedio fue 47.30 años y 63.7% eran hombres. La prueba de interacción de apoyo social × resiliencia para hacer frente a situaciones difíciles × país indicó diferencias entre países (b = −0.63, p = 0.043, IC 95% [1.24, −0.02]). En Argentina, los participantes con mayor apoyo social y resiliencia para hacer frente a situaciones difíciles mostraron síntomas depresivos más bajos; y aquellos con menor apoyo social y resiliencia para hacer frente a situaciones difíciles, mostraron síntomas depresivos más altos. Este efecto no se observó en los participantes de Miami.

RESUMO

Long-acting injectable (LAI) pre-exposure prophylaxis (PrEP) has the potential to facilitate adherence and transform HIV prevention. However, little LAI PrEP research has occurred among women, who face unique barriers. We conducted 30 in-depth interviews with HIV-negative women from 2017-2018 across six sites (New York; Chicago; San Francisco; Atlanta; Washington, DC; Chapel Hill) of the Women's Interagency HIV Study. Interviews were recorded, transcribed, and analyzed using thematic content analysis. Few women expressed interest in PrEP and when prompted to choose a regimen, 55% would prefer LAI, 10% daily pills, and 33% said they would not take PrEP regardless of formulation. Perceived barriers included: (1) the fear of new-and perceived untested-injectable products and (2) potential side effects (e.g., injection-site pain, nausea). Facilitators included: (1) believing shots were more effective than pills; (2) ease and convenience; and (3) confidentiality. Future studies should incorporate women's LAI PrEP-related experiences to facilitate uptake.

RESUMO

Black women living with HIV (BWLWH) in the U.S. face microaggressions based on race, gender, HIV-status, and sexual orientation. We examined changes in daily microaggressions and related distress among 143 BWLWH in Miami, FL. Microaggression-related distress increased from 52% at baseline/October, peaked at 70% during the holidays (November/December), declined to 55% in March when COVID-19 social distancing began, and peaked to 83% in June/July 2020 during widespread Black Lives Matters protests. Baseline viral suppression was associated with lower microaggressions across the 9-months. Microaggression-related distress may change due to social context and research is needed on microaggressions and viral load overtime.


RESUMEN: Las mujeres de raza negra que viven con el VIH (MNVV) en los EE. UU. enfrentan microagresiones basadas en la raza, el género, el estado serológico del VIH y la orientación sexual. Examinamos los cambios en las microagresiones diarias y el estrés relacionado entre 143 MNVV en Miami, FL. El estrés relacionado con la microagresión aumentó del 52% en la línea de base/octubre, alcanzó un máximo del 70% durante las vacaciones (noviembre/diciembre), disminuyó al 55% en marzo cuando comenzó el distanciamiento social por el COVID-19 y alcanzó un máximo del 83% en junio/julio de 2020 durante las protestas generalizadas de Black Lives Matters. La supresión viral inicial se asoció con menores microagresiones durante los 9 meses. El estrés relacionada con la microagresión puede cambiar debido al contexto social y se necesitan investigaciones sobre las microagresiones y la carga viral con el tiempo.

RESUMO

The syndemic conditions of low education, childhood maltreatment, depression, HIV, alcohol and cocaine use, and obesity have been established as independent risk factors for cardiovascular risk, but research examining the association between syndemic conditions and cardiovascular risk in high-risk populations is lacking. A total of N = 503 participants underwent an ultrasound of the carotid artery to assess for atherosclerotic plaque. Participants, HIV-infected (n = 202) and HIV-uninfected (n = 301) with and without a history of cocaine use, were a mean age of 36.13 years (SD = 9.51); 50% were male, and 62% were African-American. Each syndemic condition was associated with 8% greater odds of atherosclerotic plaque (OR = 1.08), 9% greater odds of systolic blood pressure (OR = 1.09), and 10% greater odds of diastolic blood pressure (OR = 1.10). Multilevel research, interventions, and public policy initiatives are needed to activate stakeholders at each level to maximize their impact at a community level among populations with high rates of syndemic conditions.

RESUMO

Our objective was to examine the association between healthcare payer type and missed HIV care visits among 1,366 US women living with HIV (WLWH) enrolled in the prospective Women's Interagency HIV Study (WIHS). We collected secondary patient-level data (October 1, 2017-September 30, 2018) from WLWH at nine WIHS sites. We used bivariate and multivariable binary logistic regression to examine the relationship between healthcare payer type (cross-classification of patients' ADAP and health insurance enrollment) and missed visits-based retention in care, defined as no-show appointments for which patients did not reschedule. Our sample included all WLWH who self-reported having received HIV care at least once during the two consecutive biannual WIHS visits a year prior to October 1, 2017-September 30, 2018. In the bivariate model, compared to uninsured WLWH without ADAP, WLWH with private insurance + ADAP were more likely to be retained in care, as were WLWH with Medicaid only and private insurance only. In the adjusted model, WLWH with private insurance only were more likely to be retained in care compared to uninsured WLWH without ADAP. Private health insurance and ADAP are associated with increased odds of retention in care among WLWH.

RESUMO

BACKGROUND: Cumulative burden of multiple mental health conditions may worsen physical health outcomes in vulnerable populations. Accordingly, identifying cumulative burdens of mental health conditions that may affect HIV treatment and care can guide public health strategies to reduce their impact on HIV-related health outcomes. This study examined the relationship between the cumulative burden of mental health conditions and factors associated with engagement in HIV care in Argentina. METHOD: Data for this study was obtained at baseline from Conexiones y Opciones Positivas en la Argentina 2 (COPA2). Participants (N = 360) were cisgender patients living with HIV who were lost to care, recruited from seven clinics serving people living with HIV in four Argentine urban centers. Cumulative burden of mental health conditions (i.e., depressive symptoms, problematic substance use, unhealthy alcohol use, and psychotic symptoms) was assessed. RESULTS: Every one-point increase in the number of mental health conditions present was associated with a decrement in patient-provider communication (b = - 0.22, p < .001), self-efficacy (b = - 0.13, p = .012), and motivation for adherence (b = - 0.11, p = .039). CONCLUSION: This study found cumulative burden of depression, problematic substance use, unhealthy alcohol use, and psychotic symptoms to be negatively associated with factors related to engagement in HIV care. Results highlight the importance of identification and treatment of challenges to mental health, in order to ameliorate their influence on engagement in HIV care.
