Comparative Study
Optimizing Fetal Aneuploidy Screening in an Austere Military Clinical Environment: A Prenatal Cost Comparison.
Austere clinical settings, including remote military installations, face unique challenges in screening pregnant women for aneuploidy. The objective of this study was to compare the direct and indirect prenatal costs of traditional 2-part serum-based screening to cell-free DNA (cfDNA) for detection of trisomies 18 and 21 for a military treatment facility with limited in-house perinatal resources. ⋯ Cell-free DNA as an initial screening strategy offers enhanced detection rates for trisomies 18 and 21 but remains more costly than traditional screening when incorporating direct and indirect expenses. In a low volume setting with limited resources, the added cost may be justified given the implications of unrecognized aneuploidy.

Sleep disturbance is prevalent among service members; however, little is known about factors that compromise sleep in unique operational environments, such as naval ships. Given the importance of sleep to health and performance, it is critical to identify both causes and potential solutions to this serious issue. The objective of this qualitative study was to elucidate the barriers to sleep and the strategies service members use to improve their sleep and combat fatigue while living and working aboard ships (i.e., underway). ⋯ Service members reported many unique barriers to sleep in the shipboard environment, yet many did not report the use of strategies to mitigate them. Further, few used alerting techniques when fatigued. This at-risk population could benefit from targeted educational interventions on sleep-promoting behaviors, prioritization of sleep, and fatigue mitigation.

Increases in C-reactive protein (CRP) are used to track the inflammatory process of COVID-19 and are associated with disease state progression. Decreases in heart rate variability (HRV) correlate with worsening of disease states. This observational study tracks changes in HRV relative to changes in CRP in COVID-19 patients. ⋯ Substantial decreases in HRV preceded elevations in CRP in the ensuing 72 hours with a 90.9% positive predictive value. Early detection of increasing inflammation may prove vital in mitigating the deleterious effects of an abnormal inflammatory response, particularly in COVID-19 patients. This capability could have a major impact in triage and care of moderate to severe COVID-19 patients in major medical centers as well as field hospitals. This study demonstrates the potential value of short-segment, intermittent HRV analysis in COVID-19 patients.

Per Joint Trauma System guidelines, military anesthesiologists are expected to be ready to lead an Acute Pain Service with regional anesthesia in combat casualty care. However, regional anesthesia practice volume has not been assessed in the military. The objective of this study was to assess regional anesthesia utilization among current residents and graduates of U.S. military anesthesiology residency programs. ⋯ These findings highlight the need for creative solutions to increase regional anesthesia training in military anesthesiology programs and continued ability to implement skills, such that all military anesthesiologists have adequate practice for deployed responsibilities.

We present the experience of our U.S. Navy Role 2's deployment to the U.S. Central Command area of responsibility in support of Operation Inherent Resolve and serving a multinational, joint-service military base. We detail our efforts to establish a low-titer O (LTO) walking blood bank (WBB) in an effort to prepare for potential combat casualties. ⋯ A WBB based on LTO blood is possible in theater. In order to maximize donor pools, it is imperative that units deploying to forward areas complete titer and transfusion transmissible disease testing before arrival in theater.
