Factors Associated With COVID-19 Vaccination Among Racial/Ethnic Minority Groups With HIV in South Florida.

BACKGROUND: Racial/ethnic minority groups with HIV in the United States are particularly vulnerable to COVID-19 consequences and can significantly benefit from increased uptake of COVID-19 vaccines. This study identified factors associated with full COVID-19 vaccination among people with HIV. SETTING: Ryan White HIV/AIDS Program in Miami-Dade County, FL. METHODS: Data were collected from 299 Ryan White HIV/AIDS Program adult clients during January-March 2022 using a cross-sectional phone survey. Multivariable logistic regression was used to estimate adjusted odds ratios (aORs) with 95% confidence intervals (CIs). All analyses were weighted to be representative of the race/ethnicity and sex distribution of clients in the Ryan White HIV/AIDS Program. RESULTS: Eighty-four percent of participants were fully vaccinated with a primary vaccine series; stratified by race/ethnicity, the percentages were 88.9% of Hispanic, 72.0% of black/African American, and 67.5% of Haitian participants. Fully vaccinated participants were less likely to be black/African American than Hispanic (aOR = 0.18; 95% CI: 0.05 to 0.67) and more likely to not endorse any misconceptions about COVID-19 vaccines (aOR = 8.26; 95% CI: 1.38 to 49.64), to report encouragement to get vaccinated from sources of information (aOR = 20.82; 95% CI: 5.84 to 74.14), and to perceive that more than 50% of their social network was vaccinated (aOR = 3.35; 95% CI: 1.04 to 10.71). Experiences of health care discrimination, structural barriers to access vaccines, and recommendations from HIV providers were not associated with full vaccination. CONCLUSIONS: These findings highlight the importance of delivering accurate and positive messages about vaccines and engaging social networks to promote COVID-19 vaccination among people with HIV. This information can be leveraged to promote uptake of subsequent boosters and other recommended vaccines.

Sex differences in psychosocial and demographic factors associated with sustained HIV viral suppression in the Miami-Dade County Ryan White Program, 2017.

This exploratory study examined sex differences in psychosocial and demographic factors associated with sustained HIV viral suppression (SVS). The study population included 6,489 Miami-Dade Ryan White Program (RWP) clients receiving services during 2017; administrative data was analyzed. SVS was defined as having all viral load tests during 2017 below 200 copies/ml. Multilevel logistic regression models accounted for clustering by medical case management site. Models were stratified by sex. Overall, a higher proportion of females did not achieve SVS (23.5%) than males (18.1%). For females (n = 1,503), having acquired HIV perinatally and not having a partner oradult household member were associated with not achieving SVS. For males (n = 4,986), lacking access to food, Black or Haitian race/ethnicity, problematic substance use, and unknown physician were associated with not achieving SVS. For both sexes, younger age, lower household income, ever having an AIDS diagnosis, feeling depressed or anxious, and experiencing homelessness were associated with not achieving SVS. Elements of the transition from adolescent to adult HIV care that may differentially impact female clients and factors associated with disclosure should be explored further. Male clients may require additional support for food security. Improving culturally specific care for Haitian and non-Hispanic Black male clients should also be explored.

HIV Care Access During the COVID-19 Pandemic as Perceived by Racial/Ethnic Minority Groups Served by the Ryan White Program, Miami-Dade County, Florida.

The Ryan White Program (RWP) in Miami-Dade County, Florida made several modifications to keep HIV care accessible during the COVID-19 Pandemic, including expanding telehealth services, increasing access to HIV medications, and waiving required lab tests for service recertification. We assessed ease of access to medical providers, medical case managers, and antiretroviral medications during the COVID-19 Pandemic among 298 Non-Hispanic Black, Hispanic, and Haitian people with HIV (PWH) served by the RWP Part A, Miami-Dade County, Florida using a telephone-administered survey between October 2020 and January 2021. Overall, most clients reported similar or better access compared to before the Pandemic. Use of videocalls to communicate with HIV medical providers varied by race/ethnicity: Hispanics (49.6%), Non-Hispanic Blacks (37.7%), and Haitian clients (16.0%). Results suggest the modifications helped maintain access to care during an unprecedented health crisis. Permanently adopting many of these modifications should be considered to continue to facilitate access to care.

Profiles of immune infiltration in abdominal aortic aneurysm and their associated marker genes: a gene expression-based study.

Immune-mediated inflammation plays a key role in the pathology of abdominal aortic aneurysm (AAA). We aimed to use a computational approach to profile the immune infiltration patterns and related core genes in AAA samples based on the overexpression of gene signatures. The microarray datasets of AAA and normal abdominal tissues were acquired from gene expression omnibus (GEO) database. We evaluated the composition of immune infiltrates through microenvironment cell populations (MCP)-counter. Weighted gene correlation network analysis (WGCNA) was employed to construct the co-expression network and extract gene information in the most relevant module. Functional and pathway enrichment analysis was performed and immune infiltration related core genes were screened. AAA tissues had a higher level of infiltration by cytotoxic lymphocytes, NK cells, T cells, fibroblasts, myeloid dendritic cells, and neutrophils than normal aorta. The red module was strongly correlated with the infiltrating levels of T cells and cytotoxic lymphocytes. Gene ontology (GO) and pathway analyses revealed that genes in the most relevant module were mainly enriched in T cell activation, regulation of lymphocyte activation, cytokine-cytokine receptor interaction, and chemokine signaling pathway, etc. The expression of GZMK, CCL5, GZMA, CD2, and EOMES showed significant correlations with cytotoxic lymphocytes, while CD247, CD2, CD6, RASGRP1, and CD48 expression were positively associated with T cell infiltration. In conclusion, we comprehensively analyzed profiles of infiltrated immune cells in AAA tissues and their associated marker genes. Our data may provide a novel clue to indicate the underlying molecular mechanisms of AAA formation in terms of immune infiltration.

Factors Associated With the Recurrence, Persistence, and Clearance of Asymptomatic Bacterial Vaginosis Among Young African American Women: A Repeated-Measures Latent Class Analysis.

BACKGROUND: Although risk factors of recurrent and persistent bacterial vaginosis (BV) have been explored in the literature, the longitudinal incidence patterns of BV remain elusive. METHODS: We conducted a secondary analysis of longitudinal data from a randomized clinical trial of metronidazole treatment for asymptomatic BV. Repeated-measures latent class analysis was used to identify distinct longitudinal patterns of incident BV cases. Multinomial regression analysis was used to determine the predictors of class membership. The multivariable model included age, last BV treatment, douching frequency, birth control, sexual risk behavior, and assignment to treatment arm. RESULTS: A total of 858 African American women who were asymptomatic for BV were included in the analysis. Three emergent patterns of BV for 12 months were identified by repeated-measures latent class analysis: persistent (55.9%), recurrent (30.5%), and clearance (13.5%). Participants who had douched at least once had significantly lower odds to be in the recurrent class versus the clearance class (adjusted odds ratio [adjOR], 0.55; 95% confidence interval [CI], 0.18-0.63). Women who had sex with women had significantly lower odds of belonging to the persistent class versus the clearance class (adjOR, 0.38; 95% CI, 0.22-0.68) and the recurrent class (adjOR, 0.43; 95% CI, 0.23-0.81). Those who were assigned to the treatment arm had significantly increased odds of being in the recurrent class versus the clearance class (adjOR, 1.92; 95% CI, 1.22-3.03). Women older than 21 years were significantly more likely to be in the recurrent class (adjOR, 1.88; 95% CI, 1.17-3.00) than in the clearance class. CONCLUSIONS: Assessment of BV cases revealed distinct patterns of recurrence and persistence of BV, which were significantly associated with douching, being in the treatment arm, and being a woman who had sex with women.
