PrEP Disparities Among Transgender Feminine, Transgender Masculine, Nonbinary, and Gender Expansive Youth and Young Adults in the United States.

This study assessed disparities in pre-exposure prophylaxis (PrEP) use among transgender and gender expansive youth and young adults (N = 477) between 15 and 24 years old in the CARES (ATN 149) and TechStep (ATN 160) study protocols within the National Adolescent Medicine Trials Network for HIV/AIDS Interventions (ATN). Structural equation modeling was used to test mediation pathways between gender identity and PrEP uptake among the full sample and stratified by sex assigned at birth. Lifetime PrEP uptake was higher among those assigned male at birth (26%) versus assigned female at birth (9%), explained by greater structural and behavioral risks and perceived need for PrEP, especially among trans women.

Adolescents may accurately self-collect pharyngeal and rectal clinical specimens for the detection of Chlamydia trachomatis and Neisseria gonorrhoeae infection.

Background: The COVID-19 pandemic illuminated the benefits of telemedicine. Self-collected specimens are a promising alternative to clinician-collected specimens when in-person testing is not feasible. In this study, we assessed the adequacy of self-collected pharyngeal and rectal specimens for the detection of Chlamydia trachomatis and Neisseria gonorrhoeae among individuals undergoing chlamydia and gonorrhea screening.

Cooking behaviors are related to household particulate matter exposure in children with asthma in the urban East Bay Area of Northern California.

Background: Asthma is a common childhood disease that leads to many missed days of school and parents' work. There are multiple environmental contributors to asthma symptoms and understanding the potential factors inside children's homes is crucial.
