Combat-related injuries from improvised explosive devices occur commonly to the lower extremity and spine. As the underbody blast impact loading traverses from the seat to pelvis to spine, energy transfer occurs through deformations of the combined pelvis-sacrum-lumbar spine complex, and the time factor plays a role in injury to any of these components. Previous studies have largely ignored the role of the time variable in injuries, injury mechanisms, and warfighter tolerance. The objective of this study is to relate the time or temporal factor using a multi-component, pelvis-sacrum-lumbar spinal column complex model. ⋯ With adequate time for the underbody blast loading to traverse the pelvis-sacrum-spine complex, distal structures are spared while proximal/spine structures sustain severe/unstable injuries. The time factor may have implications in seat and/or seat structure design in future military vehicles to advance warfighter safety.

Traumatic brain injury (TBI) is highly prevalent among active duty service members (ADSMs) and imposes a significant health burden, particularly on mental health (e.g., post-traumatic stress disorder [PTSD] and depressive symptoms). Little is known about how TBI setting characteristics impact PTSD and depressive symptom expression in service members undergoing interdisciplinary TBI care. ⋯ There was a differential impact of TBI settings, particularly between TBI sustained before military service and that from combat deployment among ADSMs enrolled in outpatient TBI programs. This may be indicative of differences in the characteristics of these environments (e.g., injury severity) or the impact of such an event during recovery from current TBIs. The large percentage of ADSMs who present with clinically-elevated mental health symptoms after treatment may suggest the need for additional resources to address mental health needs before, during, and after treatment in TBI programs.

U.S. Army regulations require all soldiers to undergo annual audiometric testing to maintain hearing readiness. The standard method of monitoring hearing in the DoD is via multi-person testing in sound-treated booths using the Defense Occupational and Environmental Health Readiness System-Hearing Conservation. COVID-19 significantly hindered the standard method, resulting in alarming declines in hearing readiness. In response, the Army Hearing Program initiated a pilot program to use boothless audiometers to supplement standard methods to increase hearing readiness. ⋯ Significant reductions in patient encounters as a direct result of the COVID-19 pandemic have led to innovative solutions leveraging boothless audiometers. While this has aided the primary mission to maintain a medically ready force, innovations from this endeavor highlight several additional improvements relative to current standards of care that should be considered for permanent inclusion in DoD Hearing Conservation Programs.

Chronic pain is highly prevalent among soldiers leading to costly impacts on disability and readiness. Depression and anxiety (D&A) are frequently comorbid with chronic pain, but previous studies tend to focus on reporting the odds of co-occurrence. The aim of this study was to examine the association of properly diagnosed D&A disorders on chronic pain indicators among active duty soldiers. ⋯ Soldiers who have chronic pain with coexisting D&A disorders experience a greater degree of perceived negative impacts. Consequently, attentiveness to proper diagnosis and treatment of coexisting clinical mood disorders is an essential step in fully addressing chronic pain management.

The Cohesion Assessment Team (CAT) provides battalion and brigade command teams with actionable insight into the climate of their unit and the presence of certain harmful behaviors. This assessment, initiated by the Vice Chief of Staff of the Army and initially managed by the Headquarters Department of the Army's People First Task Force, employs a framework from the Center for Army Professional Leadership to structure data and findings. ⋯ The CAT focuses on providing leaders at brigade and below with relevant and actionable information to help inform their internal decision-making to improve their unit's climate. This capability is distinct in many ways, including its non-attributional systems focus and its methodical approach to quickly collecting and triangulating multiple data points. Additionally, the CAT helps leaders identify areas under their control that will impact unit climate, similar to the feedback that training events provide on unit readiness. Army leadership deemed the CAT pilot a success, and responsibility for future CATs was transferred to the Training and Doctrine Command (TRADOC) in October 2022.
