Confidentiality concerns are a well-established barrier to sexual health services for adolescents. These barriers are likely even greater for young men who have sex with men (YMSM), who often experience stigma at multiple levels. This study examined the relationship between state laws regulating minors' access to confidential sexual health services, sexual behavior, and lifetime HIV testing among a large, representative sample of sexually active male high school students from the 2019 state-level Youth Risk Behavior Surveillance System (23 states; N = 17,509).

Exhausted T (T) cells are characterized by upregulation of coinhibitory molecules and reduced polyfunctionality. T cells in the TME experience an immunosuppressive metabolic environment via reduced levels of nutrients and oxygen and a buildup of lactic acid.

Methods: Using data from the 2016 to 2019 National Survey on Drug Use and Health, we used logistic regression models to estimate the interactive effects of sexual identity, race/ethnicity, and gender on past-year DUIA among adults who used alcohol and DUIC among adults who used cannabis, accounting for covariates. Using model estimates and linear combinations, we calculated the predicted probabilities of each outcome and compared sexual identity differences within and across race/ethnicity and gender.
Introduction: Substance use disorders (SUD) are associated with HIV acquisition and care disruptions. Most research focuses on clinical samples; however, we used a nationally representative, community-based sample to estimate SUD treatment need and utilization by HIV status.
Methods: We included participants from the 2015-2019 National Survey on Drug Use and Health aged 18 and older who met past-year DSM-IV SUD criteria (n = 22,166).
Gender refers to the socially constructed roles, behaviors, and attributes that a particular society considers appropriate for men and women based on assumptions about biological sex. It also operates as a major social organizing principle that confers unequal power, status, and resources to men and women, with direct consequences for health. Historic patriarchal and misogynistic beliefs and values are reinforced through social institutions, including health science, which reify gender inequities.

This was exacerbated by psychological stressors stemming from the COVID-19 pandemic; these experiences intersected with YYA unique developmental stage. Here we explored LGBTQ+ YYA's pandemic-related experiences, focusing on intersections between stigma and belonging, developmental processes, and their relationship to mental health.

However, realizing the public health potential of LAI ART requires reaching patients who face barriers to daily oral ART adherence and thus can clinically benefit from alternative treatment modalities. Ryan White HIV/AIDS Program Part A medical case management (MCM) programs provide an array of services to address barriers to HIV care and treatment among economically and socially marginalized people living with HIV.

There is an urgent need to examine challenges navigating the evolving HIV treatment and cure research landscape. From August to October 2022, we conducted 26 semistructured interviews with biomedical researchers and community members representing a predominantly woman demographic to explore the complexity of navigating the rapidly evolving HIV therapeutic and HIV cure research landscape.

However, current research efforts toward a cure for HIV focus predominantly on cisgender men. The under-representation of women in HIV cure clinical studies is particularly problematic given data suggesting that sex-dependent phenotypes limit scientific discovery.

However, limited research has explored structural drivers of Black YMSM' criminal justice involvement, particularly co-occurring forms of discrimination. This article examines the temporal relationship between perceived racial discrimination, perceived sexual orientation discrimination, and community-level HIV discrimination and criminal justice involvement among Black YMSM in North Carolina.

Methods: We searched four databases through May 21st, 2022: PubMed, Embase, PsycInfo and the Web of Science according to a specified search strings. Study inclusion criteria include: (1) cohort and case-control peer-reviewed studies published in English; (2) studies comparing neurodevelopmental outcomes among children with prenatal opioid-exposure (prescribed or used non-medically) vs.
Aim: In the context of the continued overdose epidemic, recent population estimates of opioid use in highly affected groups, such as people at risk for or people living with HIV (PLWH), are essential for service planning and provision. Although nonmedical opioid use is associated with HIV transmission and with lowered adherence and care engagement, most studies rely on clinic-based samples and focus on medical use of opioids only. We examine associations between opioid-related outcomes by HIV status in a community-based nationally representative sample.

In the case of sexual and gender minority youth (SGMY), life trajectories are shaped not only by targeted, SGM-focused policies, but also by social policies more broadly which may have unique impacts on SGMY given their social position. However, little work has explored the pathways that connect both targeted and universal social policies and the health and well-being of SGMY.

Patterns of research participation are particularly salient at this moment given emerging biomedical prevention paradigms. This paper explores the perspectives of Black and Latino young men who have sex with men (BL-YMSM) regarding research recruitment and eligibility criteria, how their experiences influence willingness to enroll in a given study, and implications for the veracity and representativeness of resulting data.

However, there are many advantages in studying CAR-T cell biology in an immunocompetent setting. We generated a fully murine CAR targeting CD105 (endoglin), a component of the TGFβ receptor expressed on the surface of certain solid tumors and acute leukemias.

Long-acting PrEP modalities hold promise for HIV prevention among PWID, but product preferences remain poorly understood. From September to November 2021, we conducted qualitative interviews with 28 HIV-negative, adult (≥18 years) PWID in San Diego County, CA, to explore their perspectives on daily oral PrEP pills and long-acting PrEP modalities (i.
