Oxygen supplementation is frequently used in critically injured trauma casualties in the combat setting. Oxygen supplies in the deployed setting are limited so excessive use of oxygen may unnecessarily consume this limited resource. We describe the incidence of supraphysiologic oxygenation (hyperoxia) within casualties in the Department of Defense Trauma Registry (DoDTR). ⋯ In our dataset, more than 1 in 5 casualties overall had documented hyperoxia on ABG measurement, 1 in 3 intubated casualties, and almost 1 in 2 TBI casualties. With limited oxygen supplies in theater and logistical challenges with oxygen resupply, efforts to avoid unnecessary oxygen supplementation may have material impact on preserving this scarce resource and avoid potential detrimental clinical effects from supraphysiologic oxygen concentrations.

Seasonal aeroallergens commonly cause allergic conjunctivitis, rhinorrhea, sinusitis, and cough in sensitized individuals. These clinical symptoms are the result of IgE-mediated type I hypersensitivity reactions, which trigger the degranulaton of mast cells and basophils. In contrast, aeroallergens are not common precipitants of urticarial dermatitis, which is driven by a cell-mediated type IV hypersensitivity reaction. ⋯ Further, his skin disease rapidly cleared within 24 hours of leaving southern Texas. Because of the recalcitrant nature of his condition upon returning home, he was considered unfit for further military service. This case not only highlights the growing link between IgE and chronic skin disease, but also the impact aeroallergens can have on the medical readiness and world-wide deployability of Airmen, Sailors, Soldiers, and Marines.

This study was conducted to determine what physical and physiological characteristics contribute to the performance of an urban operation casualty evacuation (UO) and its predictive test, FORCE combat (FC) and describe the metabolic demand of the UO in female soldiers. ⋯ This study showed that modifiable factors such as body composition, PF on IMTP and L.VO2max are key contributors to performance on UO and FC performance.

Soldiers have a higher risk for developing psychiatric disorders that require treatment; often with antidepressants. However, antidepressants as well as the psychiatric disorder, may influence military readiness in several ways. In the general population, early discontinuation of antidepressant treatment is often seen. It is yet unknown whether this occurs to a similar extent in soldiers. The objective of this study was to evaluate discontinuation of antidepressant use by Dutch soldiers in the first 12 months after start and determinants thereof. ⋯ More than half of the soldiers discontinued their prescribed antidepressant within 3 months and after 6 months, only 30% were still on antidepressants.
