AbstractForensic fractographic features of bone reliably establish crack propagation in perimortem injuries. We investigated if similar fracture surface features characterize postmortem fractures. Experimentally induced peri‐ and postmortem fractures were used to assess if fractographic features vary as bone elasticity decreases during the postmortem interval (PMI). Thirty‐seven unembalmed, defleshed human femoral shafts from males and females aged 33–81 years were fractured at varying PMIs with a drop test frame using a three‐point bending setup and recorded with a high‐speed camera. Vital statistics, cause of death, PMI length, temperature, humidity, collagen percentage, water loss, fracture energy, and fractography scores were recorded for each sample. Results showed that fractographic features associated with perimortem fractures were expressed in PMIs up to 40,600 accumulated degree hours (ADH), or 60 warm weather days. Hackle was the most consistently expressed feature, occurring in all fractures regardless of ADH. The most variable characteristics were wake features (78.4%) and arrest ridges (70.3%). Collagen percentage did not correlate strongly with ADH (r = −0.04, p = 0.81); however, there was a strong significant correlation between ADH and water loss (r = 0.74, p < 0.001). Multinomial logistic regression showed no association between fractographic feature expression and ADH or collagen percentage. In conclusion, forensic fractographic features reliably determine initiation and directionality of crack propagation in experimentally induced PMIs up to 40,600 ADH, demonstrating the utility of this method into the recent postmortem interval. This expression of reliable fractographic features throughout the early PMI intimates these characteristics may not be useful standalone features for discerning peri‐ versus postmortem fractures.

Introduction: Eye movement desensitization and reprocessing (EMDR) is an evidence-based psychotherapy method designed to treat distress associated with traumatic memories. The COVID-19 pandemic has challenged providers to shift EMDR to telehealth platforms. Objectives: This research had to aims. (1) To compare EMDR in conjunction with cognitive behavioral therapy (CBT) with CBT alone for treatment of a patient population with prevalent anxiety and (2) to compare the efficacy of virtual EMDR with that of in-person EMDR in the primary care setting. Methods: Retrospective chart review of all adult patients seen by a single therapist at a primary care center was conducted from January 2018 to December 2020. Charts were reviewed for demographics, psychiatric diagnoses, number of visits, number and type of EMDR treatments, and patient health questionnaire (PHQ)-9 and general anxiety disorder (GAD-7) scores pre- and post-treatment. Results: Patients who underwent EMDR with CBT demonstrated greater decreases in PHQ-9 and GAD-7 scores than patients who had only CBT (2.4, 2.5 vs. 0.9, 1.1). However, after adjusting for total number of sessions, post-traumatic stress disorder, grief, and pain, the adjusted mean differences of change in PHQ-9 and GAD-7 scores between those who underwent EMDR with CBT and CBT-exclusive patients were not statistically significant. Similarly, the adjusted mean differences of change in PHQ-9 and GAD-7 scores between those who underwent virtual EMDR and those who had in-person EMDR were not statistically significant. Conclusions: To our knowledge, this is the first study describing the use of virtual EMDR in a primary care setting. Although our data did not provide evidence for the superiority of EMDR with CBT over CBT alone, we demonstrate that both in-person and virtual EMDR led to significantly improved GAD-7 scores.
