First responders and military personnel are particularly susceptible to behind armor blunt thoracic trauma in occupational scenarios. The objective of this study was to develop an armored thorax injury risk criterion for short duration ballistic impacts. 9 cadavers and 2 anthropomorphic test dummies (AUSMAN and NIJ 0101.04 surrogate) were tested over a range of velocities encompassing low severity impacts, medium severity impacts, and high severity impacts based upon risk of sternal fracture. Thoracic injuries ranged from minor skin abrasions (abbreviated injury scale [AIS] 1) to severe sternal fractures (AIS 3+) and were well correlated with impact velocity and bone mineral density. 8 male cadavers were used in the injury risk criterion development. A 50% risk of AIS 3+ injury corresponded to a peak impact force of 24,900 +/- 1,400 N. The AUSMAN impact force correlated strongly with impact velocity. Recommendations to improve the biofidelity of the AUSMAN include implementing more realistic viscera and decreasing the skin thickness.

Background: The Veterans Aging Cohort Study (VACS) Index is a summary measure of routinely obtained clinical variables that predicts numerous health outcomes. Since there are currently no tools to predict acute kidney injury (AKI) in persons with HIV (PWH), we investigated the association of preadmission VACS Index with hospital AKI in PWH.
Methods: We conducted an observational study of PWH hospitalized in a New York City health system between 2010-2019.

Objective: The short-term efficacy of red blood cell (RBC) transfusion among general traumatic brain injury (TBI) patients is unclear.
Methods: We used the MIMIC database to compare the efficacy of liberal (10 g/dL) versus conservative (7 g/dL) transfusion strategy in TBI patients. The outcomes were neurological progression (decrease of Glasgow coma scale (GCS) of at least 2 points) and death within 28 days of ICU admission.

Objective: To evaluate the trabecular bone score (TBS) Z scores in long-distance runners with bone stress injuries (BSIs) in whom the bone mineral density (BMD) Z score is more than -1.0 (Aim 1) and whether the number of runners with abnormal TBS Z scores would be higher in those with BSI in trabecular-rich sites as compared with cortical-rich sites (Aim 2).
Design: Retrospective cohort study.

Background: The inferior alveolar nerve (IAN), a crucial branch of the trigeminal nerve, innervates the mandible. Precise knowledge of IAN positioning ensures surgical safety.
Methods: This cross-sectional study analyzed head and neck computed tomography scans from Maharaj Nakorn Chiang Mai Hospital.

BACKGROUND Appropriate management of patients who have fallen is crucial for reducing damage and mortality. We report the case of a patient who fell from a seated position, which caused traumatic liver injury, with gastrointestinal symptoms as the primary patient concern. CASE REPORT A woman in her 80s who was living independently fell from a seated position during the daytime.
