RESUMO
There are significant disparities in HIV pre-exposure prophylaxis (PrEP) use that disproportionately impact Black transgender women. Medical mistrust and discriminatory experiences in healthcare settings have been identified as critical barriers to equitable PrEP implementation. This qualitative study examines Black transgender women's experiences in healthcare to better understand how patient-provider relationships can help overcome the challenges brought on by medical mistrust. We interviewed 42 Black transgender women about their experiences with healthcare and PrEP access. Data were analyzed using inductive thematic content analysis to develop the following themes: (1) historical and ongoing marginalization and exclusion from healthcare remains a barrier to PrEP use; (2) Many providers continue to be unprepared to prescribe PrEP; (3) Providers can act as important advocates and sources of support; and (4) Compassionate, trusting patient-provider relationships can facilitate PrEP use. Our results highlight the importance of supportive and positive patient-provider relationships and demonstrate how providers can build trusting relationships with Black transgender women to help overcome barriers to healthcare and PrEP use.
RESUMO
Black men face high rates of police violence, including direct victimization and indirect exposure to or knowledge of harmful policing. This violence can result in death and physical harm, as well as in numerous poor mental health outcomes. There has been little research examining experiences of police violence experienced by Black gay and bisexual men or the effects of police brutality on HIV continuum of care outcomes. To address this important gap, in this exploratory study, we examined the effects of police brutality on engagement in HIV care and adherence to antiretroviral medications. Cross-sectional survey data were collected from 107 Black gay and bisexual men living with HIV. The path analysis showed that men with greater exposure to police violence had increased symptoms of post-traumatic stress disorder and were more likely to have missed HIV care appointments in the past year. Additionally, there was a significant indirect effect of exposure to police violence on missed medication doses via PTSD symptoms.

People living with HIV (PLH) who live in rural areas of the United States (US) face more challenges to obtaining medical care and suffer higher mortality rates compared to non-rural PLH. Compared with younger PLH, older PLH (age 50+) also face additional challenges to maintaining their health and wellbeing. Despite the heightened barriers to receiving care and remaining adherent to treatment among older rural PLH, few interventions to increase viral suppression and improve quality of life exist for this population. We pilot-tested four remotely-delivered interventions-group-based social support, group-based stigma-reduction, individual strengths-based case management, and individual technology detailing-aimed to improve care engagement and quality of life in rural older PLH in the southern US. Participants (N = 61, Mage = 58, 75% male) completed surveys and self-collected blood specimens at baseline and 3 months; in between, they were randomized to 0-4 interventions. We assessed feasibility, acceptability, and preliminary impact on medication adherence, viral suppression, quality of life, depressive symptoms, and hypothesized mediating mechanisms. More than 80% participated in assigned intervention(s), and 84% completed the study. Interventions were highly acceptable to participants, with more than 80% reporting they would recommend interventions to peers. More than 80% found the social support and case management interventions to be relevant and enjoyable. We found promising preliminary impact of interventions on quality of life, medication adherence, depressive symptoms, internalized stigma, and loneliness. Remotely-delivered interventions targeting rural older PLH are feasible to conduct and acceptable to participants. Larger scale study of these interventions is warranted.
RESUMEN: A pesar de las múltiples barreras para la adherencia a la medicación y la recepción de atención entre las personas mayores de zonas rurales que viven con el VIH, existen pocas intervenciones para mejorar la supresión viral y la calidad de vida para esta población. Realizamos pruebas piloto de intervenciones realizadas de forma remota (grupos de apoyo social, grupos de reducción del estigma, manejo de casos basado en los puntos fuertes y "technology detailing") entre las personas que viven con el VIH en zonas rurales del sur de Estados Unidos. Los participantes (N = 61, Medad = 58, 75% hombres) completaron encuestas y recolectaron muestras de sangre al inicio y a los 3 meses; en el medio, fueron asignados al azar a 04 intervenciones. Evaluamos la viabilidad, la aceptabilidad y el impacto preliminar. Más del 80% participó en la(s) intervención(es) y el 84% completó el estudio. Las intervenciones fueron muy aceptables para los participantes; más del 80% consideró que las intervenciones de apoyo social y gestión de casos eran relevantes y agradables. Las intervenciones tuvieron un impacto preliminar prometedor sobre la calidad de vida, la adherencia a la medicación, los síntomas depresivos, el estigma y la soledad. Las intervenciones realizadas a distancia dirigidas a las personas que viven con el VIH en zonas rurales de edad avanzada son viables y aceptables, y se justifica un estudio a mayor escala.

The HIV epidemic continues to expand in Russia, with suboptimal levels of care uptake. This qualitative study aimed to characterize social capital resources and lived stigma experiences, coping, and disclosure among care-nonadherent men who have sex with men (MSM) living with HIV in Russia. Twenty-five HIV-positive MSM - recruited online - completed in-depth interviews over Zoom, with data analyzed using MAXQDA software. Stigma was more likely to be encountered in interactions with persons with whom social ties were weaker such as medical providers and relatives, particularly males. Close friends - often other HIV-positive MSM and female relatives - were the most supportive and least stigmatizing. Similar persons were most often considered for HIV serostatus disclosure. Coping strategies to reduce the impact of stigma included ignoring stigmatizing experiences, seeking support from members of one's social circle, minimizing contact with stigmatizing persons, seeking new relationships with persons who are also HIV-positive, proactively reducing stigma through involvement in advocacy roles, and correcting myths and educating others about HIV infection. These findings underscore the need for interventions to assist HIV-positive MSM in building accepting social capital resources to reduce the impact of stigma and to build support within their social networks, often with other HIV-positive MSM.

This study examined the relationship between exposure to community violence and HIV care engagement among 107 Black gay or bisexual men living with HIV in Chicago. Measures assessed the importance of demographic covariates (age, annual income, health insurance status, and years living with HIV), community violence exposures, mental health, social support, in explaining variations in missed doses of antiretroviral therapy (ART) medication and missed HIV care appointments. Results showed that participants who reported higher rates of exposure to community violence were two times more likely to have missed ART doses and HIV care appointments. Participants who reported depression scores were two times more likely to have greater non-ART adherence. Finally, older participants were more likely to report fewer missed ART doses. More research is needed to clarify the mechanisms between age or depression and ART adherence given community violence exposure. Health care providers should screen for depression when attempting to promote better ART adherence and keeping HIV care appointments for Black gay and bisexual men living with HIV. Younger Black gay and bisexual men living with HIV may be more vulnerable than older men for missed ART doses and may require additional screening and follow-up.

Black sexual minority men who have sex with men (MSM) in the United States are at disparate risk for contracting HIV infection, but pre-exposure prophylaxis (PrEP) use is suboptimal. Social network methods were used to recruit a community sample of racial minority MSM and transgender women (TGW) in two Midwestern US cities. 250 PrEP-eligible (HIV-negative) participants completed measures assessing current and intended PrEP use; demographic characteristics; PrEP knowledge, attitudes, norms, stigma, and self-efficacy; and structural barriers to PrEP. Multivariate analyses established predictors of current and intended PrEP use. Only 12% of participants reported currently using PrEP, which was associated with greater PrEP knowledge and not having a main partner, with trends for greater PrEP use by younger participants and those with partners living with HIV. Among participants not currently on PrEP, strength of PrEP use intentions was associated with higher PrEP knowledge, PrEP descriptive social norms, and PrEP use self-efficacy. This study is among few to directly compare Black who have adopted PrEP with those who have not. Its findings underscore the potential benefits of employing social network approaches for strengthening PrEP use peer norms, increasing PrEP knowledge and self-efficacy, and optimizing PrEP uptake among racial minority MSM and TGW.

The goal of this study was to examine the effects of racial discrimination, depression, and Black LGBTQ community support on HIV care outcomes among a sample of Black sexually minoritized men living with HIV. We conducted a cross-sectional survey with 107 Black sexually minoritized men living with HIV in Chicago. A path model was used to test associations between racial discrimination, Black LGBTQ community support, depressive symptoms, and missed antiretroviral medication doses and HIV care appointments. Results of the path model showed that men who had experienced more racism had more depressive symptoms and subsequently, missed more doses of HIV antiretroviral medication and had missed more HIV care appointments. Greater Black LGBTQ community support was associated with fewer missed HIV care appointments in the past year. This research shows that anti-Black racism may be a pervasive and harmful determinant of HIV inequities and a critical driver of racial disparities in ART adherence and HIV care engagement experienced by Black SMM. Black LGBTQ community support may buffer against the effects of racial discrimination on HIV care outcomes by providing safe, inclusive, supportive spaces for Black SMM.

Previous research has demonstrated associations between experiences of microaggressions and negative mental and physical health outcomes, and national organizations such as the Centers for Disease Control and Prevention have acknowledged racism as a public health issue. Individuals with multiple marginalized identities, such as young Black men who have sex with men and transgender women, are commonly affected by discrimination and stigma, contributing to health disparities. One possible path by which microaggressions are linked to negative health outcomes for these groups is their impact on individuals' decisions to conceal their sexual identity, in some cases leading to increased stress and use of maladaptive coping strategies. We surveyed 280 young Black male (86%) and transgender or non-binary (14%) individuals between the ages of 16-25 years old (M = 21.68, SD = 2.73) who reported being recently sexually active with men about their experiences with intersectional microaggressions, concealment of their sexual identity, psychological distress, and substance use before and during sexual activity. Structural equation modeling revealed that experiences of microaggressions were associated with greater sexual identity concealment, and concealment partially mediated the relationship between microaggressions and psychological distress. While microaggressions were associated with greater substance use, sexual identity concealment did not mediate this relationship. Findings have implications for addressing health disparities among this population.

INTRODUCTION: This study aimed to assess prevalence of back pain among older people living with HIV (PLH) in rural areas of the United States (US); compare the presence of comorbidities, socioeconomic factors, and sociodemographic factors among older PLH in rural areas of the US with and without back pain; and examine the associations between back pain, depression, and QOL among older PLH in rural areas of the US. METHODS: Cross-sectional data was collected among US rural dwelling PLH of at least 50 years of age. Multiple logistic regression was performed to examine the association between back pain and depression. Multiple linear regression was performed to assess the association between back pain and QOL. RESULTS: A total of 38.8% (n = 164) of participants self-reported back pain. PLH with back pain were more likely to have depression (60.87%, n = 98). PLH with back pain had lower mean QOL scores (53.01 ± 18.39). Back pain was associated with greater odds of having depression (OR 1.61 [CI 0.99-2.61], p = .054) and was significantly associated with lower QOL (p < .001). CONCLUSIONS: Prevention strategies to reduce back pain and poor HIV outcomes among PLH living in rural areas of the US are needed.
RESUMO
Intersectional stigma and discrimination have increasingly been recognized as impediments to the health and well-being of young Black sexual minority men (YBSMM) and transgender women (TW). However, little research has examined the relationship between intersectional discrimination and HIV pre-exposure prophylaxis (PrEP) outcomes. This study with 283 YBSMM and TW examines the relationship between intersectional discrimination and current PrEP use and likelihood of future PrEP use. Path models were used to test associations between intersectional discrimination, resilience and social support, and PrEP use and intentions. Individuals with higher levels of anticipated discrimination were less likely to be current PrEP users (OR = 0.59, p = .013), and higher levels of daily discrimination were associated with increased likelihood of using PrEP in the future (B = 0.48 (0.16), p = .002). Greater discrimination was associated with higher levels of resilience, social support, and connection to the Black LGBTQ community. Social support mediated the effect of day-to-day discrimination on likelihood of future PrEP use. Additionally, there was a significant and negative indirect effect of PrEP social concerns on current PrEP use via Black LGBTQ community connectedness. The results of this study highlight the complexity of the relationships between discrimination, resilience, and health outcomes.

This study conducted 28 semi-structured, in-depth interviews with Young Black Men who have Sex with Men in Chicago to investigate the impact of COVID-19 on their HIV care and ancillary service access. The qualitative analysis identified both negative and positive effects. The negative effects included: (l) mixed disruptions in linkage to and receipt of HIV care and ancillary services, and (2) heightened concerns about police and racial tensions in Chicago following the murder of George Floyd, contributing to possible disruption of retention in care. The positive effects included: (1) the ability to reflect and socially connect, contributing to heightened self-care and retention in care, and (2) some improvements in receipt of medical care. These findings suggest that while COVID-19 disruptions in care reduced in-person use of HIV care, the expansion of telemedicine allowed more administrative tasks to be handled online and focused in-person interactions on more substantive interactions.

In 2020, the COVID-19 pandemic emerged against a backdrop of long-standing racial inequities that contributed to significant disparities in COVID-19 mortality, morbidity, and eventually, vaccination rates. COVID-19 also converged with two social crises: anti-Black racism and community and police violence. The goal of this study was to examine the associations between community violence, police violence, anti-Black racism, and COVID-19 vaccination. Survey data were collected from a sample of 538 Black residents of Chicago between September 2021 and March 2022. Structural equation modeling was used to test associations between neighborhood violence, police violence, racism, medical mistrust, trust in COVID-related information, depressive symptoms, and having received a COVID-19 vaccination. In line with predictions, neighborhood violence had a significant indirect effect on vaccination via trust in COVID-related information from a personal doctor. Additionally, racism had a significant indirect effect on vaccination via trust in COVID-related information from a personal doctor, as well as via medical mistrust and trust in COVID-related information from a personal doctor. These findings add to the growing body of literature demonstrating the importance of medical mistrust when examining COVID-19 vaccination disparities. Furthermore, this study highlights the importance of considering how social and structural factors such as violence and racism can influence medical mistrust.
RESUMO
Complex models in physics, biology, economics, and engineering are oftensloppy, meaning that the model parameters are not well determined by the model predictions for collective behavior. Many parameter combinations can vary over decades without significant changes in the predictions. This review uses information geometry to explore sloppiness and its deep relation to emergent theories. We introduce themodel manifoldof predictions, whose coordinates are the model parameters. Itshyperribbonstructure explains why only a few parameter combinations matter for the behavior. We review recent rigorous results that connect the hierarchy of hyperribbon widths to approximation theory, and to the smoothness of model predictions under changes of the control variables. We discuss recent geodesic methods to find simpler models on nearby boundaries of the model manifold-emergent theories with fewer parameters that explain the behavior equally well. We discuss a Bayesian prior which optimizes the mutual information between model parameters and experimental data, naturally favoring points on the emergent boundary theories and thus simpler models. We introduce a 'projected maximum likelihood' prior that efficiently approximates this optimal prior, and contrast both to the poor behavior of the traditional Jeffreys prior. We discuss the way the renormalization group coarse-graining in statistical mechanics introduces a flow of the model manifold, and connect stiff and sloppy directions along the model manifold with relevant and irrelevant eigendirections of the renormalization group. Finally, we discuss recently developed 'intensive' embedding methods, allowing one to visualize the predictions of arbitrary probabilistic models as low-dimensional projections of an isometric embedding, and illustrate our method by generating the model manifold of the Ising model.

BACKGROUND: The COVID-19 pandemic adversely affected sexual health services. Given the burden of sexually transmitted infections (STIs) on sexual and gender minorities (SGMs), we estimated incidence of self-reported STI diagnoses and factors associated with STI diagnoses among SGMs during the pandemic's first year. METHODS: A cohort of 426 SGM persons, 25 years or older, recruited in Chicago, Milwaukee, Detroit, Minneapolis, and Houston completed 5 online surveys from April 2020 to February 2021. Persons self-reported on each survey all health care provider STI diagnoses. Kaplan-Meier was used to estimate the cumulative risk of STI diagnoses, stratified by human immunodeficiency virus (HIV) status. Factors associated with STI diagnoses were assessed with a longitudinal negative binomial regression. RESULTS: Median age was 37 years, and 27.0% were persons living with HIV (PLH). Participants reported 63 STIs for a cumulative incidence for PLH and HIV-negative persons of 0.19 (95% confidence interval [CI], 0.13-0.29) and 0.12 (95% CI, 0.09-0.17), respectively. Regardless of HIV, a younger age and changes in health care use were associated with STI diagnoses. Among HIV-negative persons, the rate of STI diagnoses was higher in Houston than the Midwest cities (adjusted relative risk, 2.37; 95% CI, 1.08-5.20). Among PLH, a decrease in health care use was also associated with STI diagnoses (adjusted relative risk, 3.53; 95% CI, 1.01-12.32 vs no change in health care services), as was Hispanic ethnicity and using a dating app to meet a sex partner. CONCLUSIONS: Factors associated with STI diagnoses during the COVID-19 pandemic generally reflected factors associated with STI incidence before the pandemic like geography, HIV, age, and ethnicity.

Objectives. To investigate resilience strategies used by Black gay, bisexual, and other men who have sex with men (MSM) to navigate racism and heterosexism. Methods. In 2019, we conducted in-depth interviews with 46 Black MSM in Milwaukee, Wisconsin, and Cleveland, Ohio. Thematic analysis, informed by intersectionality, was used to identify intersectional resilience within the context of participants' lives. Results. Our analyses revealed ways in which Black MSM respond to stigma and oppression. We identified the following themes that capture these experiences: pride in intersectional identities, perseverance, community advocacy, and social support. Our analyses reveal how men draw on these assets and resources to positively adapt despite experiences of racism and heterosexism. Conclusions. Intersectional resilience can support Black MSM in navigating racism and heterosexism. However, public health interventions at the institutional and system levels are needed to directly target the root causes of oppression and support resources that facilitate intersectional resilience.

Researchers are increasingly recognizing the importance of studying and addressing intersectional stigma within the field of HIV. Yet, researchers have, arguably, struggled to operationalize intersectional stigma. To ensure that future research and methodological innovation is guided by frameworks from which this area of inquiry has arisen, we propose a series of core elements for future HIV-related intersectional stigma research. These core elements include multidimensional, multilevel, multidirectional, and action-oriented methods that sharpen focus on, and aim to transform, interlocking and reinforcing systems of oppression. We further identify opportunities for advancing HIV-related intersectional stigma research, including reducing barriers to and strengthening investments in resources, building capacity to engage in research and implementation of interventions, and creating meaningful pathways for HIV-related intersectional stigma research to produce structural change. Ultimately, the expected payoff for incorporating these core elements is a body of HIV-related intersectional stigma research that is both better aligned with the transformative potential of intersectionality and better positioned to achieve the goals of Ending the HIV Epidemic in the United States and globally. (Am J Public Health. 2022;112(S4):S413-S419. https://doi.org/10.2105/AJPH.2021.306710).

Prior research has highlighted the impact of the COVID-19 pandemic on HIV prevention services within the U.S., but few studies have explored this impact through an exploratory, qualitative lens. In this study, we sought to highlight the voices of young sexual minority men (YSMM) 17-24 years old and explored the perceived impact of the pandemic on HIV prevention among a diverse, nationwide sample of YSMM who participated in synchronous online focus group discussions between April and September 2020. Forty-one YSMM described the negative effects of the COVID-19 pandemic on HIV testing and prevention services, including limited and disrupted access to HIV testing, HIV pre-exposure prophylaxis (PrEP), and HIV post-exposure prophylaxis. COVID-19-related challenges were compounded by ongoing, pre-COVID-19 barriers experienced by YSMM in the U.S. For instance, many YSMM relocated back home with family, causing men to avoid HIV prevention services for fear of outing themselves to relatives. YSMM also worried about placing their family at increased risk of COVID-19 by attending clinical appointments. YSMM who did seek HIV prevention services, including access to PrEP, experienced significant barriers, including limited appointment availability and services not tailored to YSMM. Further efforts are needed to support YSMM re-engaging in HIV prevention during and after the COVID-19 era.

Unsupervised learning makes manifest the underlying structure of data without curated training and specific problem definitions. However, the inference of relationships between data points is frustrated by the "curse of dimensionality" in high dimensions. Inspired by replica theory from statistical mechanics, we consider replicas of the system to tune the dimensionality and take the limit as the number of replicas goes to zero. The result is intensive embedding, which not only is isometric (preserving local distances) but also allows global structure to be more transparently visualized. We develop the Intensive Principal Component Analysis (InPCA) and demonstrate clear improvements in visualizations of the Ising model of magnetic spins, a neural network, and the dark energy cold dark matter ([Formula: see text]) model as applied to the cosmic microwave background.
RESUMO
BACKGROUND: Providing permanent supportive housing to chronically homeless persons living with human immunodeficiency virus (PLH) contributes to improved human immunodeficiency virus (HIV) outcomes, including adherence to antiretroviral therapy (ART). This study seeks to understand whether certain components of housing, namely intensity of case management and specialized HIV housing programs, affects ART adherence for PLH in supportive housing. METHODS: From 2015 to 2019 we conducted quantitative assessments with 157 PLH in supportive housing at baseline, 6-, 12-, and 18-month postbaseline to identify factors associated with ART adherence. General Estimating Equations for repeated measures were performed to assess bivariate and multivariate measures. RESULTS: Two thirds of PLH in supportive housing reported 95% or greater adherence to ART. Multivariate analyses indicate that neither intensity of case management services nor specialized housing for PLH were associated with greater ART adherence. Greater time since diagnosis was positively associated with ART adherence. Greater depressive symptoms and African American race were negatively associated with ART adherence. CONCLUSIONS: Study findings reveal that although prior research has established the importance of receipt of housing for homeless PLH, the type or intensity of case management services associated with that housing may not be as important as simply being housed. Our results highlight the importance of considering mental health and more recent HIV diagnosis when developing treatment and case management plans to enhance residents' ART adherence.

As communities struggle with how to cope with the health and social consequences of coronavirus disease 2019 (COVID-19), sexual and gender minority men living with or affected by the HIV/AIDS epidemic have important insights into how to cope with uncertainty, public health protocols, and grief. We recruited sexual and gender minority men using online networking apps from April 18-24, 2020 to enroll a longitudinal cohort. We analyzed baseline qualitative data from open-ended responses using content analysis to examine how the HIV/AIDS epidemic has helped sexual minority men with the current COVID-19 pandemic. Of the 437 participants who completed the survey, 155 (35%) indicated that HIV/AIDS had helped them cope with COVID-19. Free-response data from those 135 of those participants clustered around four themes: (1) experience having lived through a pandemic, (2) experience coping with stigma, (3) familiarity with public health protocols, and (4) belief in collective action. Based on the experiences of these men, public health approaches centered on resilience and collective action could be particularly helpful in responding and coping with COVID-19-especially if the pandemic persists over longer periods of time.
