Drill sergeants work under mentally and physically challenging conditions. The current study examined self-reported rates of physical injuries in drill sergeants; rates of treatment-seeking for injuries; perceived barriers toward treatment-seeking; and associated demographic and environmental factors. ⋯ This study is the first to examine injury occurrence, treatment-seeking, and perceived barriers to treatment-seeking in U.S. Army drill sergeants. Building on previous studies that showed the negative effects of sleep deprivation on the safety and behavioral health of drill sergeants, the current study gives further evidence of the negative effects of such sleep deprivation, this time in the domain of physical injuries. The results suggest that pursuing strategies that allow for healthier sleep duration may contribute to injury reduction.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent of coronavirus disease 2019 (COVID-19), was first identified in 2019 in Wuhan, China, and has rapidly spread across the world. As of April 2021, SARS-CoV-2 has infected more than 140,000,000 and caused more than 3,000,000 deaths globally. In November 2020, the monoclonal antibody bamlanivimab was approved by the FDA for non-hospitalized patients with SARS-CoV-2 (COVID-19) who possessed risk factors for progression to severe COVID-19. This provided a treatment option that may help prevent hospitalization. ⋯ Global improvement of symptoms within 24 to 72 hours of infusion was reported by 94.4% of patients receiving bamlanivimab; however, statistical significance could not be determined due to the small sample size and lack of placebo group due to study design. Furthermore, ED visits and hospital admissions were analyzed, but with only six patients in the comparison group, the relative risk was not statistically significant and could not be precisely estimated. In the future, this study can be replicated with both larger control/treatment arms to validate the initial results of this small, retrospective, cohort study.

Observational Study
Anthropometrics and Body Composition Predict Physical Performance and Selection to Attend Special Forces Training in United States Army Soldiers.
Anthropometrics and body composition characteristics differentiate many types of athletes and are related to performance on fitness tests and tasks in military personnel. Soldiers competing to enter elite units must demonstrate physical fitness and operational competence across multiple events. Therefore, this study determined whether anthropometrics and body composition predicted physical performance and selection for special forces training among soldiers attending the rigorous Special Forces Assessment and Selection (SFAS) course. ⋯ Anthropometrics and body composition are predictors of physical performance and SFAS success. Since these measures are modifiable (excluding height), they may be the focus of intervention studies aiming to improve performance in arduous military training courses, sports that require competition in multiple events, and occupations that have varied physical demands, such as firefighting, law enforcement, and construction.

Safe and effective vaccines against severe acute respiratory syndrome-associated coronavirus 2 are essential tools in the fight against the coronavirus disease 2019 (COVID-19) pandemic. However, hesitancy to vaccination is a major barrier to achieving herd immunity, particularly among a population working on a military base. To better understand the perceptions and concerns of these individuals, a voluntary survey was conducted. ⋯ Younger age and medical occupation were independent risk factors for vaccine hesitancy and these individuals were less likely to recommend vaccination to a friend or family member. We also identified several key concerns related to vaccination hesitancy, in particular those related to short- and long-term side effects, and the spread of misinformation. Among military personnel, these findings carry important implications that may negatively impact mission readiness, a matter that merits further investigation. Our COVID-19 vaccination hesitancy findings can be used to guide targeted interventions at future vaccination campaigns in a military population.

On February 24, 2022, Russia began a military invasion of Ukraine. Missile and air strikes were reported throughout the country, shortly followed by a large ground invasion from multiple directions. Four major theaters developed: the Kyiv offensive, the Northeastern Ukraine offensive, the Eastern Ukraine offensive, and the Southern Ukraine offensive, with continued missile and air strikes far into Western Ukraine. ⋯ There are 15 operating nuclear reactors in Ukraine. Each is vulnerable to an attack or sabotage that could precipitate a malfunction and possible release of radioactive isotopes. In this short commentary, we will discuss radiobiologic data obtained after the analysis of historical nuclear power plant (NPP) accidents and emphasize new challenges for nuclear security when NPPs are found and are possible targets within a conflict zone.
