This study used machine learning methods to examine features from 26 posttraumatic symptoms assessed during the first 8 weeks following traumatic exposure in order to develop a pragmatic algorithm to predict PTSD. The resulting algorithm accurately predicted PTSD and contained the mean scores from three items: nervousness, re-hashing, and fatigue.

This pilot implementation study outlines a curriculum on digital psychiatry at a large US-based psychiatry residency training program, including an evaluation of learner confidence in the appraisal and clinical recommendation of digital mental health apps.

ShapeAXI is a framework for shape analysis that uses a multi-view approach, capturing 3D objects from various angles and analyzing them with 2D CNNs. It features an automatic N-fold cross-validation process and generates explainability heat-maps, demonstrating its effectiveness in classifying condyles and cleft patient shapes, with its implementation available on GitHub.

The current study developed and validated a brief bedside screening tool that could be used with recent sexual assault survivors to understand who is at risk for chronic and impairing posttraumatic stress (PTS) and could benefit from early intervention. The sample included 547 women presenting to one of thirteen hospitals across the US for acute … Read more

Dynamic functional network connectivity (dFNC) analysis is a widely used approach for studying brain function and offering insight into how brain networks evolve over time. Functional dysconnectivity between different brain regions has been reported in schizophrenia, yet the neural mechanisms behind it remain elusive. This manuscript presents a complementary novel approach that optimizes FNC, as … Read more

Post-traumatic stress disorder (PTSD) and alcohol use disorder (AUD) are highly comorbid and individual differences in response to stress suggest resilient and susceptible populations. The current review discusses the advantages of using predator odor stressors to better understand PTSD pathophysiology and neurobiological mechanisms associated with stress reactivity and subsequent increases in alcohol drinking. In addition, … Read more
