Low-income, urban-dwelling Black adults are disproportionately affected by traumatic experiences, post-traumatic stress disorder (PTSD), and depression and encounter inequities in treatment access. In addition to the benefits Mindfulness-Based Cognitive Therapy (MBCT) for depression, there is preliminary evidence of successful symptom reduction in PTSD via MBCT across two prior pilot studies in veterans. Studies examining the effects of MBCT among trauma-exposed Black adults remains limited, and examination of effects across specific PTSD clusters is almost nonexistent.

Article Synopsis
  • Researchers aimed to create and validate Methylation Risk Scores (MRS) using machine learning to identify individuals at risk for PTSD based on genomic and trauma exposure data.
  • The study developed three models: eMRS (which combines trauma exposure and methylation data), MoRS (which relies only on methylation data), and MoRSAE (which adjusts MoRS for trauma exposure).
  • The eMRS model showed the best performance with a 92% accuracy, and all models were able to predict post-deployment PTSD significantly, suggesting that including trauma exposure improves risk assessment.

Heart failure (HF) is an important comorbidity for patients with ischemic stroke, present in 11 %-18 % of patients, and may also independently increase the risk of first-ever and recurrent ischemic stroke. HF is categorized based on ejection fraction (EF) into HF with reduced (HFrEF), mildly-reduced (HFmrEG) and preserved ejection fraction (HFpEF), with the efficacy of HF therapies differing between the three subcategories. Despite this classification, the incidence, recurrence rates and outcomes of ischemic stroke do not appear to differ significantly between the three subtypes, even when considering the concurrent presence of atrial fibrillation.

Chronic pain is prevalent among individuals with higher body weight and associated with greater impairment. As a result, weight loss is a common recommendation for pain management among those with higher body weight. Body weight is an appealing target because it is modifiable and evidence-based treatments to produce weight loss are well-established.

Unhealthy alcohol use is a common, often unaddressed behavior associated with increased risk for acquisition of HIV and may also be associated with decreased adherence to oral pre-exposure prophylaxis (PrEP) among gay, bisexual, and other men who have sex with men (MSM) living in the United States. To inform future alcohol-reduction interventions among individuals engaging in PrEP care, we sought to explore perspectives on alcohol use, PrEP adherence, and the acceptability of alcohol use treatment options for MSM prescribed oral formulations of PrEP in the Northeastern United States. Between February 2019 and July 2020, we conducted semi-structured interviews with 15 MSM without HIV who were prescribed PrEP and screened positive for unhealthy alcohol use with AUDIT-C ≥ 4 and were receiving care in Providence, Rhode Island or New Haven, Connecticut.
