Clinical investigations have attributed lumbar spine injuries in combat to the vertical vector. Injury prevention strategies include the determination of spine biomechanics under this vector and developing/evaluating physical devices for use in live fire and evaluation-type tests to enhance Warfighter safety. While biological models have replicated theater injuries in the laboratory, matched-pair tests with physical devices are needed for standardized tests. The objective of this investigation is to determine the responses of the widely used Hybrid III lumbar spine under the vertical impact-loading vector. ⋯ The Hybrid III lumbar spine when subjected to vertical impact simulating underbody blast levels showed that the impact is transmitted via the axial loading mechanism. This finding paralleled the results of axial force predominance over shear forces and axial loading injuries to human spines. Axial forces increased with increasing velocity suggesting the possibility of developing injury assessment risk curves, i.e., the manikin spine does not saturate, and its response is not a step function. It is possible to associate probability values for different force magnitudes. A similar conclusion was found to be true for both magnitudes of added effective torso mass at the superior end of the manikin spinal column. Additional matched-pair tests are needed to develop injury criteria for the Hybrid III male and female lumbar spines.

Obstructive sleep apnea (OSA) is a treatable cause of daytime sleepiness and associated medical problems that can negatively impact soldier readiness and performance. This study examined adherence to positive airway pressure (PAP) by soldiers who were newly diagnosed with OSA and prescribed PAP therapy and participated in a Knowledge, Skills, and Attitudes (KSA) behavioral intervention class. ⋯ KSA could be a behavioral intervention that enhances PAP adherence with a booster session implemented at the 90 days mark.

Military exposures may present a cumulative load and increased individual susceptibility to negative health outcomes. Currently, there are no comprehensive and validated environmental exposure assessment tools covering the full spectrum of occupational and environmental exposures for Veterans. The Veterans Affairs (VA) War Related Illness and Injury Study Center in Washington, DC, developed the Veteran Military Occupational and Environmental Exposure Assessment Tool (VMOAT) to establish a structured, comprehensive self-report tool that captures military and non-military occupational and environmental exposures. The VMOAT is clinically insightful, modular, and flexible for adding novel exposures, meeting the needs of modern evolving threats and exposures in both clinical and research settings. This manuscript reviews the ongoing development and validation plans for the VMOAT. ⋯ VMOAT development supports the 2022 Promise to Address Comprehensive Toxics Act and fits into the existing VA exposure assessment approach as a standardized, comprehensive self-reported exposure assessment tool. It can be utilized as a stand-alone instrument or supplemented by clinician interviews in research or specialty evaluation programs. The collected VMOAT self-report information on military occupational and environmental exposures will allow direct evaluation with objective measures of exposure and health outcomes. These data outcomes have a high potential to guide the DoD and VA environmental exposure risk mitigation and risk communication efforts.

Between June 2021 and December 2022, the Practice-Based Implementation (PBI) Network conducted a pilot to study the optimization of behavioral health technicians (BHTs) within military behavioral health (BH) care system specialty BH clinics. Behavioral health technicians are paraprofessionals found in all branches of the military, and with training across a variety of clinic functions. Behavioral health technicians support BH specialty providers in many clinic functions (i.e., administrative, case management, clinical, and outreach). The primary aim of the BHT optimization pilot was to increase BHTs' involvement in clinical care. ⋯ Overall, individualized clinic BHT optimization plans and strategies appear to be feasible and acceptable methods for military health system BH clinics to optimize BHTs' clinical skills.

Sleep-related disorders are associated with pain, fatigue, and deficits in cognitive performance, which may interfere with successful rehabilitation. The study objectives were to (1) quantify outpatient prescriptions for insomnia medications during the first year following combat-related amputations, (2) examine longitudinal changes in prescriptions for insomnia medications, and (3) analyze patient characteristics associated with prescriptions for insomnia medications. ⋯ The present results indicate a high prevalence of outpatient prescriptions for insomnia medications following combat-related amputations, a prevalence that is substantially higher than previously reported among active duty personnel. These findings can inform DVA/DoD guidelines for amputation care and insomnia among military subpopulations. The results highlight the need for more research on the treatment of insomnia during early postinjury rehabilitation among patients who sustained serious combat injuries.
