Suicidal ideation and attempts are considered to be graduated risks for suicide, yet they remain under studied. Suicide is among the leading causes of death in the U.S. for all individuals between the ages of 10 and 64 years. Suicide is a critical problem in the U.S. Military. The U.S. Army suicide rates surpassed civilian rates in 2008 and continue to climb steadily; with U.S. Army soldiers at more than twice the risk than U.S. civilians, and enlisted personnel at more than twice the risk of officers. Suicidal ideation and attempts are routinely reported within U.S. Army brigades using suicide-related serious incident reports (SR-SIRs). These reports could form a useful source of information for prevention planning, but to date there have been no efforts to summary these reports. This paper analyzes SR-SIRs among enlisted personnel for a 4-year period for 1 Army brigade, to test the usefulness of this information and to explore whether risk factors for attempts compared to ideation can be identified. ⋯ The study can help inform unit-specific suicide prevention and intervention strategies. Off duty hours and alcohol use are risk factors for attempts, particularly among soldiers who have sought behavioral health care. Plans to engage and support soldiers who have sought behavioral health care during off duty hours, and information regarding the risks of alcohol use, could meaningfully reduce their risk. This is the first known attempt to examine active duty U.S. Army brigade combat team SR-SIRs, and they are a potentially valuable source of health and mental health-related information.

Sexual and reproductive health is critical for the readiness of the warfighter, as costs of sexually transmitted infections and unintended pregnancy result in added health care costs, lost mission time, and impact on morale. The Multiphase Optimization Strategy (MOST) is an engineering-inspired framework used to optimize biobehavioral interventions. The Military Active-Duty Reproductive and Sexual Health (MARSH) research team applied the MOST framework to develop "Mission Wellness"-an electronic health intervention to promote sexual and reproductive health within the U.S. Military. ⋯ In line with the iterative nature of MOST, the lessons learned during the optimization trial led the MARSH team to return "Mission Wellness" to the preparation phase. The utilization of mixed (i.e., qualitative and quantitative) research methods and engagement with stakeholders at multiple levels of the military enterprise provided the information necessary to further optimize "Mission Wellness." This programmatic approach also provides a blueprint for the development of research design and testing in military health care balancing rigor and agility.

Illnesses among Navy divers degrade readiness, decrease manpower levels, and increase costs for medical care. Prior research has shown that Navy divers have high rates of the types of illnesses that might be because of diving in contaminated water. The objectives of this study were to examine medical records of U.S. Navy Sailors from 2016 to 2022 and determine if divers have higher incidence rates of health conditions that might be associated with contaminated water diving compared to non-divers. ⋯ The high RRs found for otitis externa and ear disorders support the need to devote resources to better understand the reasons for these higher risks and to develop, test, and implement targeted risk-reduction strategies. Future studies should attempt to link verified contaminated water exposures with adverse health outcomes and calculate risks based on criteria such as age and dive factors.

Post-traumatic stress disorder (PTSD) is a primary military psychiatric condition with complex etiology including strong genetic and/or environmental influences. Environmental influences and demographics can play a role in supporting underlying genetic traits for clinical utility evaluation as risk modifying factors. We are undertaking an IRB approved study to evaluate polygenic scores of PTSD risk in the adverse childhood experience and serotonin (ACES) transporter cohort. ⋯ Demographic characteristics of the ACES cohort fit a coherent model of risk for PTSD to evaluate polygenic scores. Additional research is merited to understand PTSD effects on these confounding factors.

High-rate non-penetrating blunt impacts to the thorax, such as from impacts to protective equipment, can lead to a wide range of thoracic injuries. These injuries can include rib fractures, lung contusions, and abdominal organ contusions. Ovine animals have been used to study such impacts, in a variety of ways, including in silico. To properly model these impacts in silico, it is imperative that the tissues impacted are properly characterized. The objective of this study is to characterize and validate two tissues impacted that are adjacent to the point of impact-costal cartilage and hide. Heretofore, these materials have not been characterized for use in computational models despite their nearly immediate engagement in the high-rate, non-penetrating loading environment. ⋯ Overall, we successfully characterized the mechanical behavior of the hide and costal cartilage in an ovine model. The data are intended for use in computational analogs of the ovine model for testing non-penetrating blunt impact in silico. To improve upon these models, rate sensitivity should be included, which will require additional mechanical testing.
