A psychometric assessment of a network social capital scale among sexual minority men and gender minority individuals.

BACKGROUND: Social capital, the potential for individuals to access resources through group memberships, is linked to a constellation of health outcomes. We modified a previously evaluated Constructed Family Social Capital Scale for gay, bisexual and other men who have sex with men who belong to constructed families to create a new measure of social capital within sexual minority men and gender minority individuals' social networks. METHODS: Participants were recruited from a Pride festival in Milwaukee, Wisconsin in 2018 to complete a cross-sectional survey. This analysis is restricted to 383 participants who identified as sexual minority men or gender minority individuals and completed nine items measuring social capital within their social networks. We conducted exploratory and confirmatory factor analyses to assess factor structure. Internal consistency was measured using Cronbach's alpha. RESULTS: Reliability was high, indicating the scale's utility to assess Network Social Capital among sexual minority men and gender minority individuals. A single-factor solution with high factor loadings was found for the nine-item scale. CONCLUSIONS: This study extended the psychometric properties of a preliminary social capital instrument modified from a prior study in a different population and context. The modified measure has implications for use among sexual minority men and gender minority individuals to measure social capital within social networks. Previous studies suggest that interventions to enhance social capital among sexual minority men and gender minority individuals may be beneficial for HIV prevention interventions. This tool may be relevant for the evaluation of social capital interventions within networks of sexual minority men and gender minority individuals.

Changes in institution for mental diseases (IMD) ownership status and insurance acceptance over time.

State Medicaid programs are prohibited from using federal dollars to pay institutions for mental diseases (IMDs)-freestanding psychiatric facilities with more than 16 beds. Increasingly, regulatory mechanisms have made payment of treatment in these settings substantially more feasible. This study evaluates if changing financial incentives are associated with increases in for-profit ownership among IMD facilities relative to non-IMD facilities, as well as greater increases in Medicaid acceptance among for-profit IMD facilities relative to for-profit non-IMD facilities. We used data from the 2014-2020 National Mental Health Services Surveys and examined 11 945 facility-years. Relative to non-IMDs, the increase in for-profit ownership among IMDs was 6.6 percentage points greater. The largest proportional change in Medicaid acceptance occurred among for-profit IMD facilities relative to for-profit non-IMDs (18.5 percentage points). Existing research is mixed on the quality of inpatient and residential psychiatric care provided in for-profit vs nonprofit and public facilities, as well as in IMD relative to non-IMD facilities. As payment policy increasingly incentivizes for-profit facilities to enter the psychiatric care space, we should be mindful of the impact of these decisions on patient safety.

Collectives for Care: Perspectives of Providers and Community Members in Transgender Health Care in a Southern U.S. City.

Affirming and accessible health care may improve health outcomes for trans individuals in the U.S. We explored strategies to improve affirming care for trans individuals from the perspectives of providers and transgender and non-binary community members. Forty members of a collective group of gender-affirming providers (GAP) in the southern U.S. were recruited to participate in a brief online survey. A graphical LASSO undirected network analysis approach visualized associations across outcomes and explanatory variables. Multinomial ordered (or logistic, for binary outcomes) models explored associations between a common set of explanatory variables and outcomes. Strong partial correlations (network) and statistically significant explanatory variables (ordinal and logistic models) were identified. Additionally, we conducted three focus groups (FGs) audio-recorded over Zoom with 11 community members. Four study team members analyzed the transcripts using content analyses. Survey results indicated that higher frequency of attendance at monthly provider meetings, additional training, and provision of training and consultation were associated with greater perceived competence among GAP members. To improve services, FG participants suggested treating patients as experts, increasing diversity and representation among providers, and expanding the GAP group. These results highlight the critical need to design and implement community-identified interventions to improve gender-affirming services and enhance provider training.

Human Cell-Derived Matrix Composite Hydrogels with Diverse Composition for Use in Vasculature-on-chip Models.

Microphysiological and organ-on-chip platforms seek to address critical gaps in human disease models and drug development that underlie poor rates of clinical success for novel interventions. While the fabrication technology and model cells used to synthesize organs-on-chip have advanced considerably, most platforms rely on animal-derived or synthetic extracellular matrix as a cell substrate, limiting mimicry of human physiology and precluding use in modeling diseases in which matrix dynamics play a role in pathogenesis. Here, the development of human cell-derived matrix (hCDM) composite hydrogels for use in 3D microphysiologic models of the vasculature is reported. hCDM composite hydrogels are derived from human donor fibroblasts and maintain a complex milieu of basement membrane, proteoglycans, and nonfibrillar matrix components. The use of hCDM composite hydrogels as 2D and 3D cell culture substrates is demonstrated, and hCDM composite hydrogels are patterned to form engineered human microvessels. Interestingly, hCDM composite hydrogels are enriched in proteins associated with vascular morphogenesis as determined by mass spectrometry, and functional analysis demonstrates proangiogenic signatures in human endothelial cells cultured in these hydrogels. In conclusion, this study suggests that human donor-derived hCDM composite hydrogels could address technical gaps in human organs-on-chip development and serve as substrates to promote vascularization.

PrEP awareness, willingness, and likelihood to use future HIV prevention methods among undergraduate college students in an ending the HIV epidemic jurisdiction.

OBJECTIVE: Identify factors associated with PrEP awareness, willingness, and future prevention modalities among undergraduate college students. PARTICIPANTS: Undergraduates (N = 701) were recruited from a private university, a public research university, and a private historically Black college and university for an online survey. METHODS: Upon multiple imputations, a multivariate logistic model, a multivariate multinomial model, and independent multivariate ordinal logistic models were used to calculate Rubin's rules-pooled adjusted odds ratios for PrEP awareness, willingness, and future HIV prevention methods. RESULTS: Only 33.4% of students had heard of and 32.4% were willing to take PrEP. PrEP willingness was higher among sexual minority students compared to heterosexual/straight students (OR = 1.65; 95% CI: 1.03-2.63); p = .036). The likelihood to take a future vaccine or antibody prophylaxis treatment was higher than the likelihood to take injectable PrEP or implants. CONCLUSIONS: Interventions to increase PrEP uptake and willingness among undergraduates should emphasize equity in HIV education and include future prevention modalities.

Perceptions of HIV Research Participation Among Gay, Bisexual, and Other Men who Have Sex with Men and Transgender and Nonbinary Adults: Results From a Midwest Pride Event.

Human immunodeficiency virus (HIV) continues to disproportionately affect gay, bisexual, and other men who have sex with men (GBM) and transgender and nonbinary (trans/NB) individuals. This study investigated attitudes toward participation in HIV survey research, guided by Emanuel's framework for ethical clinical research (e.g., risk-benefit ratio, fair participant selection, respect for participants, social value, and collaborative partnership). GBM (n = 294) and trans/NB (n = 86) persons recruited at a Pride event in Milwaukee completed a survey assessing risks and benefits of participation in, and comfort responding to, sexual health surveys. Participants reported few ethical concerns (e.g., privacy and confidentiality), with notable differences by race, sexual orientation and gender identity, and prior research experiences. Implications for HIV research with GBM and trans/NB individuals are discussed.

COVID-19 Exposure, Stress, and Mental Health Outcomes: Results From a Needs Assessment Among Low Income Adults in Central North Carolina.

This study focuses on identifying COVID-19 related exposure, stress, and mental health concerns in the larger Charlotte, North Carolina region, an area with many low-income and under resourced communities. A community-academic partnership conducted a regional COVID-19 needs assessment. Low-income adults (N = 156) completed an online-administered survey of demographic information, COVID-19 exposure, stress, coping-related factors, and mental health. Frequency data showed that common COVID-19 related stressors included job exposure, lost job/income, and increased home responsibilities. Frequency data further showed elevated screening risk rates for mental health concerns were observed for post-traumatic stress (83.3%), depression (52.2%), problematic drinking (50.0%), generalized anxiety (43.0%), and suicide (40.4%). Bivariate correlation and multivariate regression models identified robust mental health risk factors including COVID-19 related stress affecting close persons, fear/worry reaction to the pandemic, and use of venting as a coping strategy; protective factors included active coping and problem-focused coping beliefs. Findings are discussed with respect to informing regional public health efforts during the pandemic.
