Background

Unpredictability in the child’s environment has recently emerged as a significant and unique form of early life adversity (ELA). Cross-sectional studies have linked childhood unpredictability with increased post-traumatic stress disorder (PTSD) symptoms in adults; however, no prospective studies have tested the link between childhood unpredictability and PTSD risk in later life, nor what processes, such as increased anhedonia symptoms, might mediate such risk. Here, we leveraged three distinct prospective, longitudinal cohorts to test the hypothesis that unpredictability during childhood contributes to adult PTSD via worsening anhedonia symptoms.

Methods

Participants were male service members (n=314), adult females (n=170), and adolescents …

Depression Due To Combined Dexamethasone And Cyproheptadine Abuse For Weight Gain, Sanjana Sateesh, Jatin Kumar, Dhananjay Ardawatia, Kishor M, Shashidhara Kc, Srikanth Ms

Digital Journal of Clinical Medicine

Cyproheptadine, an H1 antihistamine, and Dexamethasone, a long-acting steroid, are often misused in combination for addressing self-perceived body image issues and have become a popular but dangerous ‘weight gain cocktail’, often available over the counter without any prescription. This case describes a 25-year-old man who had self-prescribed the above-mentioned drugs in combination to address his self-perceived lean physique. This resulted in a significant weight gain, followed by an abnormal increase in appetite, which affected his daily life. Upon cessation, it resulted in rebound weight changes, depressive features, along with features of corticosteroid withdrawal, which required multidisciplinary management.

An Odd Protocol For An Agent-Based Model Of Hepatitis C Virus Transmission In A Homogeneous Syringe-Sharing Network, Seun Ale, Que Thi Nguyet Nguyen Dr., John D. Kelleher Prof., Elizabeth Hunter Dr.

Reports

The model described in this ODD is an agent-based model of hepatitis C virus (HCV) transmission among people who inject drugs (PWID). The model assumes homogeneous mixing among syringe-sharing agents, without any form of heterogeneity in the agents interactions or syringe-sharing attitude. All syringe-sharing PWID are treated as identical in terms of their interaction frequency and syringe-sharing probability. Interactions are generated dynamically using proximity-based sampling at each timestep (one day), allowing agents to form syringe-sharing interactions based on spatial closeness. The number of daily interaction events is fixed at the population level, and each syringe-sharing agent has the same probability …

Mainstreaming Mistrust: The Shift In Us Vaccine Policy Under The Trump Administration, Sanjin Musa, Amy Estlund, Megan A. Berman

Faculty Scholarship

Department of Health and Human Services led by Robert F. Kennedy Jr., represents a significant departure from long-standing public health norms. This commentary explores how historically marginalized anti-vaccine activism has moved into the mainstream of government oversight. Key actions driving this transition include the wholesale replacement of the Advisory Committee on Immunization Practices, the departure of senior CDC officials, and the public questioning of established childhood immunization schedules. Furthermore, the administration has ceased financial support for global health entities like the World Health Organization and Gavi, the Vaccine Alliance, while canceling funding for innovative mRNA vaccine platforms.
