Initial research supports the use of propranolol to prevent posttraumatic stress disorder (PTSD); research has not examined pharmacological prevention for children. Twenty-nine injury patients (ages 10-18 years old) at risk for PTSD were randomized to a double-blind 10-day trial of propranolol or placebo initiated within 12 hours postadmission. Six-week PTSD symptoms and heart rate were assessed. Although intent-to-treat analyses revealed no group differences, findings supported a significant interaction between gender and treatment in medication-adherent participants, Delta R(2) = .21. Whereas girls receiving propranolol reported more PTSD symptoms relative to girls receiving placebo, Delta R(2) = .44, boys receiving propranolol showed a nonsignificant trend toward fewer PTSD symptoms than boys receiving placebo, Delta R(2) = .32. Findings inform gender differences regarding pharmacological PTSD prevention in youth.

The importance of mental toughness on lung transplant outcomes is unknown. We performed a pilot study to assess whether pretransplant grit and resilience are associated with short-term posttransplant outcomes. We enrolled 31 lung transplant candidates, of whom 7 (26%) had greater mental toughness, defined as the upper tertile for both grit and resilience within our cohort.

Objective: Natural variation in ovarian steroid hormones across the female lifespan contributes to an increased risk for depressive and posttraumatic stress disorder (PTSD) symptoms in women. However, minimal work has focused on understanding the impacts of reproductive aging on the brain and behavioral health of trauma-exposed women. This systematic review examines the bidirectional relationship between trauma-related psychopathology and reproductive aging.

Background: Recurrent symptom-relevant negative autobiographical memories are common in patients with emotional disorders such as anxiety and depression, even among those without a trauma-related diagnosis. Recurrent negative autobiographical memories may also contribute to distress in non-clinical populations.
Methods: To examine the prevalence of recurrent negative autobiographical memories and associated psychological features, we recruited a student sample ( = 101) and a treatment-seeking sample of patients with emotional disorders ( = 123).

Complex regional pain syndrome (CRPS) is a chronic pain disorder characterized by severe, disproportionate pain relative to an inciting event. The disorder's pathophysiology is complex, involving both central and peripheral nervous system alterations, alongside genetic, inflammatory, and psychological factors. Using data from TriNetX, this study investigated the impact of analgesic and adjuvant therapies on psychiatric outcomes in CRPS patients.

Victimization in the United States is common and has long lasting negative impacts for individuals, often disproportionately impacting those of color and from low socioeconomic communities. The Trauma Recovery Center (TRC) model aims to provide comprehensive mental health and wrap-around case management services for underserved victims of crime. Following PRISMA-ScR guidelines, we sought to further our knowledge about the impact of the TRC model.
