Factors associated with placement along the HIV prevention and care continuum among sexual minority men who use methamphetamine.

AIDS Care

March 2025

Center for Behavioral and Addiction Medicine, Department of Family Medicine, University of California, Los Angeles, Los Angeles, CA, USA.

Methamphetamine use among sexual minority men (SMM) has been associated with poor ART adherence, and reduced initiation and adherence to PrEP. From May 2021 to May 2023, 226 SMM were enrolled in , a culturally responsive smartphone application to reduce methamphetamine use and improve sexual health. Using a status-neutral approach, an ordinal variable reflected participants' placement on the HIV Prevention/Care Continuum, from HIV-positive, not taking ART, to HIV-negative, currently taking PrEP.

Seborrheic dermatitis (SD) is a chronic inflammatory skin disorder most commonly affecting areas rich in sebaceous glands, such as the scalp, face, axilla, and groin. Several factors can precipitate SD development, such as colonization of Malassezia, sebocyte activity, impaired immunity, and environmental influences. Topical antifungals, corticosteroids, and calcineurin inhibitors are the current mainstay treatment of SD.

Females remain underrepresented in opioid use disorder (OUD) research, particularly regarding dorsal striatal neuroadaptations. Chaperonins seem to play a role in opioid-induced neural plasticity, yet their contribution to OUD-related changes in the dorsal striatum (DS) remains poorly understood. Given known sex differences in opioid sensitivity, it is important to determine how chaperonin expression contributes to OUD-related adaptations in females.

Context: Sarcopenia is a disease characterized by low muscle mass and function that places individuals at greater risk of disability, loss of independence, and death. Current therapies include addressing underlying performance issues, resistance training, and/or nutritional strategies. However, these approaches have significant limitations, and chronic inflammation associated with sarcopenia may blunt the anabolic response to exercise and nutrition.

Studies show that friendships help undergraduates navigate the transition to college, but it is unclear how technology use impacts the maintenance of friendships and students' subsequent adjustment. This study fills this gap by examining how maintenance over communication technologies with pre-college and in-college friends is associated with freshmen's social adjustment to college, via two psychological processes: social support and belongingness. 194 college freshmen completed online surveys.

Tobacco 21 (T21) laws (prohibiting tobacco sales under age 21) and flavor restrictions have recently been enacted, yet little is known about the extent to which these policies shifted adolescent tobacco use. To examine the associations between state-level T21 laws and flavor restrictions with adolescent tobacco use overall and by age. We linked state-level T21 laws and flavor restrictions with individual-level data on self-reported levels of cigarette, cigar, and electronic nicotine delivery systems (ENDS) use among 979,477 (500,205 female/479,272 male) 14-18+-year-olds from the 2011-2021 Youth Risk Behavior Surveys.

Realist synthesis is a recognized methodological approach to evidence synthesis to inform evidence-based health policy and practice. The implicit assumption behind research synthesis is that the evidence it generates should be generalizable--drawing broad inferences from specific observations. While this understanding is generally shared among social scientists, tensions exist between having generalizable evidence and how this evidence can be useful in specific contexts.

Atrial fibrillation (AF) is one of the most common cardiac diseases and a complicating comorbidity for multiple associated diseases. Many clinical decisions regarding AF are currently based on the binary recognition of AF being present or absent with the categorical appraisal of AF as continued or intermittent. Assessment of AF in clinical trials is largely limited to the time to (first) detection of an AF episode.

Itaconate restrains acute proinflammatory activation of microglia MG after traumatic brain injury in mice.

Sci Transl Med

March 2025

Clinical Neuroscience Research Center, Department of Neurosurgery and Neurology, Tulane University School of Medicine, New Orleans, LA 70112, USA.

Traumatic brain injury (TBI) rapidly triggers proinflammatory activation of microglia, contributing to secondary brain damage post-TBI. Although the governing role of energy metabolism in shaping the inflammatory phenotype and function of immune cells has been increasingly recognized, the specific alterations in microglial bioenergetics post-TBI remain poorly understood. Itaconate, a metabolite produced by the enzyme aconitate decarboxylase 1 [IRG1; encoded by immune responsive gene 1 ()], is a pivotal metabolic regulator in immune cells, particularly in macrophages.
