RESUMO

PURPOSE OF REVIEW: In the era of HIV treatment as prevention (TasP), more clarity is needed regarding whether people with HIV who use stimulants (i.e., methamphetamine, powder cocaine, and crack cocaine) display elevated HIV viral load and greater immune dysregulation. RECENT FINDINGS: Although rates of viral suppression have improved in the TasP era, stimulant use was independently associated with elevated viral load in 23 of 28 studies included in our review. In the 12 studies examining other HIV disease markers, there was preliminary evidence for stimulant-associated alterations in gut-immune dysfunction and cellular immunity despite effective HIV treatment. Studies generally focused on documenting the direct associations of stimulant use with biomarkers of HIV pathogenesis without placing these in the context of social determinants of health. Stimulant use is a key barrier to optimizing the effectiveness of TasP. Elucidating the microbiome-gut-brain axis pathways whereby stimulants alter neuroimmune functioning could identify viable targets for pharmacotherapies for stimulant use disorders. Examining interpersonal, neighborhood, and structural determinants that could modify the associations of stimulant use with biomarkers of HIV pathogenesis is critical to guiding the development of comprehensive, multi-level interventions.

RESUMO

HIV-related stigma is recognized as a top barrier to achieve viral suppression in the United States, but data describing who is most affected by HIV stigma is limited. The study sought to (1) identify the relationships between HIV-related stigma and unsuppressed viral load and (2) examine whether the association between HIV stigma subtypes and unsuppressed viral load differ by age group (i.e., 18-34, 35-49, and 50+ years-old) using surveillance data from the Florida Medical Monitoring Project (n = 1195). Most participants were 50+ years-old (55%), male (71%), and Black (51%). Enacted stigma was significantly associated with unsuppressed viral loads among the 18-34-year-old age group (OR 1.68, CI 1.09-2.60). After adjusting for potential confounders, only enacted stigma was independently associated with unsuppressed viral load in the 18-34-year-old age group. Results highlight the need for targeted interventions to reduce enacted stigma among younger persons with HIV to achieve viral suppression.

RESUMO

OBJECTIVE: Sexual minority men (e.g., gay, bisexual, and other men who have sex with men) experience stigma and sexual minority stress, which are theorized to drive negative health outcomes. Sexual minority men with treated HIV display persistent immune dysregulation, which could be amplified by sexual minority stress responses to potentiate cellular aging. METHODS: This cross-sectional study included 52 sexual minority men living with HIV who had undetectable viral load (<40 copies/mL) and biologically confirmed recent methamphetamine use. Participants completed measures assessing sexual minority stress and openness about sexual minority status (i.e., outness). DNA methylation-derived outcomes included the following: the extrinsic epigenetic age acceleration clock, telomere length, naive CD4+ T-helper cells, and naive CD8+ T-cytotoxic/suppressor cells. RESULTS: After adjusting for negative affect and recent stimulant use, higher sexual minority stress was associated with a faster extrinsic epigenetic age acceleration clock ( ß = 0.29, p = .030), shorter telomere length ( ß = -0.43, p = .002), and fewer naive CD4+ (ß = -0.57, p < .001) and naive CD8+ T cells ( ß = -0.57, p < .001). Greater outness was associated with higher naive CD4+ ( ß = 0.32, p = .030) and naive CD8+ T cells ( ß = 0.38, p = .008) as well as lower plasma interleukin 6 ( ß = -0.33, p = .027). CONCLUSIONS: Sexual minority stress processes are associated with markers of cellular aging and inflammation in methamphetamine-using sexual minority men living with HIV. Longitudinal research should elucidate biobehavioral mechanisms linking sexual minority stress processes with accelerated cellular aging in those with and without HIV.

RESUMO

There is a paucity of research on the prevalence of subjective cognitive complaints in people living with human immunodeficiency virus, along with the predictors and outcomes related to these complaints. We assessed demographics, substance use and psychiatric predictors, and HIV-related outcomes associated with subjective cognitive complaint items from the Cognitive Difficulties Scale. The sample consisted of 889 people living with HIV in the survey-based Florida Cohort. Results of multivariable regression models indicated that age (45-54), hazardous alcohol consumption, more frequent marijuana use and psychiatric symptoms (depression, anxiety, PTSD) were significant predictors of subjective cognitive complaints. Subjective cognitive complaints were associated with lower adherence to antiretroviral therapy in bivariate analyses, but this relationship was no longer significant after controlling for depression, race, alcohol and drug use. Further research into the relationship between depressive and subjective cognitive complaints may provide additional avenues for intervention.


RESUMEN: Existe una escasez de investigación sobre la prevalencia de quejas cognitivas subjetivas en personas que viven con el virus de la inmunodeficiencia humana (VIH), junto con los predictores y los resultados relacionados con estas quejas. Evaluamos la demografía, el uso de sustancias y los predictores psiquiátricos, y los resultados relacionados con el VIH asociados con los ítems de quejas cognitivas subjetivas de la Escala de Dificultades Cognitivas. La muestra consistió en 889 personas que viven con el VIH en la cohorte de Florida basada en la encuesta. Los resultados de los modelos de regresión multivariable indicaron que la edad (45-54), el consumo peligroso de alcohol, el uso más frecuente de marihuana y los síntomas psiquiátricos (depresión, ansiedad, trastorno de estrés postraumático) fueron predictores significativos de quejas cognitivas subjetivas. Las quejas cognitivas subjetivas se asociaron con una menor adherencia a la terapia antirretroviral en los análisis bivariados, pero esta relación dejó de ser significativa después de controlar la depresión, la raza, el alcohol y el consumo de drogas. La investigación adicional sobre la relación entre las quejas cognitivas depresivas y subjetivas puede proporcionar vías adicionales de intervención.

RESUMO

Using data collected from the Florida Medical Monitoring Project, we sought to compare the prevalence of overall HIV-related stigma, including its subdimensions among persons with HIV and disability(s) and persons with HIV without disability in Florida. Disability was classified as having difficulty in one or more areas: activity limitations, participation restrictions, and functional or sensory activities. HIV-related stigma was assessed using the HIV Stigma Scale, which measures (1) overall stigma (2) negative self-image, (3) personalized, and (4) anticipated stigma. Multivariate analysis indicates that the crude prevalence ratios of overall stigma, including negative self-image, personalized, and anticipated stigma among persons with HIV and disability(s) were 1.43, 1.24, 1.20, and 1.23 compared to persons with HIV without disability, respectively. After adjusting for confounders, the prevalence ratios of HIV-related stigma ranged from 1.33-1.07 among persons with HIV and disability(s) compared to persons with HIV without disability. The implications of these findings reveal that persons with HIV and disability(s) are more vulnerable to HIV-related stigma. Researchers could consider distinct stigma interventions tailored towards persons with HIV and disability(s) in Florida.

RESUMO

BACKGROUND: Human Immunodeficiency Virus (HIV) disproportionately affects the Southern United States, accounting for approximately 46% of people living with HIV. HIV-related stigma is recognized as a barrier to testing, treatment, and prevention efforts. However, little is known about HIV-related stigma experiences in Florida. Using data collected from the Florida Medical Monitoring Project, we sought to examine individual characteristics associated with HIV-related stigma. METHODS: We analyzed secondary data from the 2015-2016 Medical Monitoring Project in Florida (n = 603). Stigma was measured using the 10-item HIV Stigma Scale. Exploratory factor analysis of the HIV Stigma Scale revealed three subscales: negative self-image, anticipated, and personalized stigma. Bivariate and multivariate regression models were used to determine the individual characteristics associated with the HIV Stigma Scale. RESULTS: Multivariate analysis indicated that people with severe depression scores (OR: 3.13; CI: 1.38-7.13) and persons with disability (OR: 1.64; CI: 1.03-2.61) had significantly increased odds of higher overall stigma. In the subscale analyses, negative self-image was significantly associated with alcohol misuse (OR: 2.02; CI: 1.15-3.56) depression (OR: 2.81; CI: 1.38-5.72) and/or those who identify as homosexual (OR: 0.54; CI: 0.31-0.93). Anticipated stigma was significantly associated with people who had mild-moderate depression (OR: 3.03; CI: 1.20-7.65), severe depression (OR: 2.87; CI: 1.38-5.98), identified as Black (OR: 0.60; CI: 0.37-0.98), non-injection drug use (OR: 0.55; CI: 0.33-0.91), and/or people aged 50 years and older (OR: 0.28; CI: 0.09-0.82). Personalized stigma was not associated with any of the variables examined. CONCLUSIONS: The implications of these findings reveal that certain individuals are more vulnerable to stigma. Researchers could consider distinct stigma interventions strategies based on the characteristics of specific individuals (i.e., targeting depression, disability, sexual orientation, avoidant coping, racial/ethnic groups, and youth) in Florida.

RESUMO

Purpose: Latino sexual minority men (LSMM) may experience oppression based on their ethnicity, sexual orientation, and migratory status, yet scientific literature is only beginning to explore the intersection of these experiences. This study examined mental health (MH) in relation to LSMM's experiences of intersectional oppression and affirmation. Methods: We conducted a secondary analysis of baseline data from a cohort study examining LSMM's (n = 290) health care engagement in Miami, FL, from February to September 2020. Latent class analysis (LCA) identified classes based on self-reported multiple identity discrimination (e.g., race, ethnicity, and skin color), sexual orientation stigma/affirmation, and migration-related stress. Logistic and linear regressions examined associations between class membership and anxious, depressive, post-traumatic stress, somatic symptoms, and overall MH burden. Results: The LCA revealed a three-class solution: (1) affirmed LSMM (73.8%), (2) LSMM with intersectional oppression (21.7%), and (3) LSMM with immigration stress (4.5%). The three classes varied in terms of multiple identity discrimination, sexual orientation stigma/affirmation, and migration-related stress. Compared with Class 1, Class 2 had greater conditional probabilities of reporting clinically significant depressive (p = 0.033) and post-traumatic stress symptoms (p = 0.031), and at least one MH concern (p = 0.018). Greater depressive symptoms (p = 0.007), post-traumatic stress symptoms (p = 0.049), somatic symptoms (p = 0.024), and clinically significant MH concerns (p = 0.018) were found among Class 2 than among Class 1. Conclusion: Findings identified three groups of LSMM based on their experiences of intersectional oppression and affirmation. Discrimination at the intersection of multiple identities, sexual orientation stigma/affirmation, and migration-related stress were associated with LSMM's MH outcomes, particularly among immigrants.

RESUMO

ABSTRACT: African Americans are disproportionally affected by HIV/AIDS compared with other races/ethnicities, yet few studies have examined the cultural and/or attitudinal precursors that can make African American women vulnerable to HIV-related stigma in the rural South. This study qualitatively explored the meaning and perceptions of HIV-related stigma among African American women in Florida. Thirteen semi-structured interviews were conducted using an empirical phenomenological approach. Five observer perspectives and 26 participant perspectives emerged. Participants described stigma through self-conceptualizations (e.g., ignorance), experiences (e.g., judgments), psychological dysfunction (e.g., mental health), intersectionality (e.g., race, disability), and overcoming stigma (e.g., advocacy). Our findings reveal that HIV-related stigma is unpleasant for African American women. However, over time, women in this study developed strategies to combat stigma. Elements of stigma reduction described in this study may be an important starting point for designing a culturally targeted intervention for African American women living with HIV.

RESUMO

BACKGROUND: HIV remains a significant health issue in the United States and disproportionately affects African Americans. African American women living with HIV (AAWH) experience a particularly high number of barriers when attempting to manage their HIV care, including antiretroviral therapy (ART) adherence. To enable the development and assessment of effective interventions that address these barriers to support ART adherence, there is a critical need to understand more fully the use of objective measures of ART adherence among AAWH, including electronic medication dispensers for real-time surveillance. OBJECTIVE: This study aimed to evaluate the use of the Wisepill medication event-monitoring system (MEMS) and compare the objective and subjective measures of ART adherence. METHODS: We conducted a 30-day exploratory pilot study of the MEMS among a convenience sample of community-dwelling AAWH (N=14) in rural Florida. AAWH were trained on the use of the MEMS to determine the feasibility of collecting, capturing, and manipulating the MEMS data for an objective measure of ART adherence. Self-reported sociodemographic information, including a self-reported measure of ART adherence, was also collected from AAWH. RESULTS: We found that the majority of participants were successful at using the electronic MEMS. Daily use of the MEMS tended to be outside of the usual time participants took their medication. Three 30-day medication event patterns were found that characterized ART adherence, specifically uniform and nonuniform medication adherence and nonuniform medication nonadherence. There were relatively few MEMS disruptions among study participants. Overall, adjusted daily ART adherence was 81.08% and subjective ART adherence was 77.78%. CONCLUSIONS: This pilot study on the use and evaluation of the Wisepill MEMS among AAWH in rural Florida is the first such study in the United States. The findings of this study are encouraging because 10 out of 12 participants consistently used the MEMS, there were relatively few failures, and objective adjusted daily and overall subjective ART adherence were very similar. On the basis of these findings, we think researchers should consider using the Wisepill MEMS in future studies of AAWH and people living with HIV in the United States after taking into account our practical suggestions. The following practical considerations are suggested when measuring objective medication adherence: (1) before using an MEMS, be familiar with the targeted populations' characteristics; (2) choose an MEMS that aligns with the participants' day-to-day activities; (3) ensure the MEMS' features and resulting data support the research goals; (4) assess the match among the user's ability, wireless features of the MEMS, and the geographic location of the participants; and (5) consider the cost of MEMS and the research budget.

RESUMO

INTRODUCTION: Information and communication technology (ICT) has emerged as promising to support health care consumers, including informal caregivers. This systematic review seeks to evaluate the state of the science of ICT interventions on the health of informal dementia caregivers. METHODS: We searched PubMed, CINAHL, Web of Science, and PsycINFO using concepts associated with ICT, dementia, and caregiver. Studies were assessed using the Quality Assessment Tool for Quantitative Studies. RESULTS: We identified 657 full-text publications. After removal of duplicates and title, abstract, and full-text screening, the quality of 12 studies was assessed. Studies varied in technology, implementation, results, and intervention evaluation. DISCUSSION: The methodological quality of the ICT intervention studies among dementia family caregivers was moderate to strong, yet outcome measurement was not uniform. The evidence is strongest for various forms of telephone-based interventions. However, there is a need for research that includes heterogeneous participants based on gender, race, and ethnicity.

RESUMO

BACKGROUND: Peripheral arterial disease (PAD) carries a significant morbidity and mortality. Women are more commonly affected with this condition and are mostly asymptomatic, and undertreated. The objective of the study was to develop and validate a simple risk score to identify women with PAD. HYPOTHESIS: Identifying those at early stage of the disease could help reduce the risk of complications. METHODS: Using data from the National Health and Nutrition Examination Survey 1999-2004, we identified women who had data on ankle brachial index. The cohort was divided into development (70%) and validation (30%) groups. Using variables that are self-reported or measured without laboratory data, we developed a multivariable logistic regression to predict PAD, which was evaluated in the validation cohort. RESULTS: A total of 150.6 million women were included. A diagnosis of PAD was reported in 13.7%. Age, body mass index, hypertension, diabetes mellitus, smoking, non-oral contraceptive pill usage, and parity were all independently associated with PAD. The C-statistics was 0.74, with good calibration. The model showed good stability in the validation cohort (C-statistics 0.73). CONCLUSION: This parsimonious risk model is a valid tool for risk prediction of PAD in women, and could be easily applied in routine clinical practice.
