The neurobehavioral significance of white matter hyperintensities (WMHs) seen on magnetic resonance imaging after traumatic brain injury (TBI) remains unclear, especially in Veterans and Service Members with a history of mild TBI (mTBI). In this study, we investigate the relation between WMH, mTBI, age, and cognitive performance in a large multisite cohort from the Long-term Impact of Military-relevant Brain Injury Consortium-Chronic Effects of Neurotrauma Consortium. ⋯ Subtle but important clinical relationships are identified when larger samples of mTBI participants are used to examine the relationship between history of head injury and radiological findings. Future studies should use follow-up magnetic resonance imaging and longitudinal neurobehavioral assessments to evaluate the long-term implications of WMHs following mTBI.

The reality of pilot health care avoidance behavior is often common knowledge to both pilots and aeromedical physicians, but the underlying factors leading to this behavior are less understood. In the current study, we conducted a qualitative assessment of a sample of U.S. Air Force (USAF) pilots to gather firsthand perceptions of the factors that encourage and discourage disclosure during aeromedical screening and use of mental and physical health care services, as well as recommendations to improve the USAF aeromedical health care system. ⋯ Results from firsthand interviews with pilots provide valuable information for flight surgeons to focus on building trust with their pilots to reduce health care avoidance.

Hemorrhage control and resuscitative concepts have evolved in recent years, leading to aggressive use of blood products in trauma patients. There is subsequently a potential risk for overtransfusion, adverse effects, and waste associated with unnecessary transfusion. Methods for conserving blood products are of particular importance in future large-scale combat operations where supply chains are likely to be strained. This study examined the association of emergency department (ED) arrival hemoglobin (HGB) with overtransfusion among survivors at 24 hours after major trauma at a military trauma center. ⋯ We found that the arrival HGB value was associated with overtransfusion among 24-hour survivors in a civilian trauma setting. Our findings will inform future prospective studies that investigate blood sparing clinical practice guidelines.

The National Guard (NG) served as a critical component of the U.S. response to the coronavirus disease 2019 pandemic. Understanding the impact of types of pandemic-related disaster work on mental health responses can aid in sustaining NG service members' health and preparation for subsequent activations and future pandemics. ⋯ Identifying work tasks associated with high levels of stress can help detect individuals at risk for adverse mental health responses post-exposure. Distinguishing features of high-stress work conditions can be generalized to other types of work conditions and disaster response and are important targets for planning and preventive efforts.

In ensuring the timely delivery of emergency care to Veterans, Veterans Affairs (VA) offers both emergency care services in its own facilities and, increasingly, purchases care for Veterans in non-VA (community) emergency department (ED) settings. Although in recent years emergency care coverage has become the single largest contributor to VA community care spending, no study to date has examined Veteran decision-making as it relates to ED setting choice. The purpose of this study is to identify and describe reasons why Veterans choose VA versus non-VA emergency care settings. ⋯ Our qualitative results help provide insight into how and why Veterans choose to seek emergency care. As the number of Veterans treated in non-VA EDs continues to rise, VA and non-VA ED providers as well as policy makers may benefit from understanding the challenges Veterans face when making this decision.
