Pilots of high-performance F15 and F16 jets must undergo periodic assessment of +8.5 Gz tolerance in a centrifuge, which is classified as a high-intensity exercise. Prior research has indicated that exercise performance may be correlated with alpha-actinin3 (ACTN3) and angiotensin-converting enzyme (ACE) genes, frequently termed the sports genes. This study aimed to investigate how ACTN3 and ACE genotypes correlate with high-g tolerance of Korean F15 and F16 pilots. ⋯ In a preliminary study, the RR ACTN3 genotype showed a significant correlation with +8.5 Gz tolerance. Pilots with the DI genotype showed the highest high-g tolerance in this test; however, the test pass rate was higher in pilots with the DD genotype in the preliminary study. This result shows the possibility of test passing and tolerance superiority consisting of two different factors in the relationship between high-g tolerance and ACE genotype. This study showed that pilots with the RR + DI genotype had the highest high-g tolerance, which correlated with the presence of the R and D alleles of the ACTN3 and ACE genes, respectively. However, body composition parameters were not significantly correlated with genotype. These results could suggest a plural gene effect on high-g tolerance; further follow-up is required to determine the practical usage and applications of these results.

Enterobius vermicularis is the most common helminthic infection in the United States, infecting an estimated 40 million persons. A rare complication of E. vermicularis infestation is appendicitis. The diagnosis must be considered during pathologic examination to ensure appropriate treatment with anti-helminthic therapy.

A deeper understanding of personality specifics in military personnel may increase the efficacy of health care professionals in this field. Changes in modern warfare require army officers to make decisions in complicated situations with increasing levels of autonomy. Character is traditionally regarded as a key quality in these dynamics. However, it remains unclear which character strengths are conducive to effective leadership in the military. The present study aims at mapping Czech Army cadets' and professional soldiers' perceptions of the character strengths of those officers, who they consider the best they served under. The study also examined how these perceptions vary across soldiers at different stages of their careers and how much they overlap with the same soldiers' ratings of their own strengths. In addition, a regression analysis, to outline combinations of strengths for various aspects of character-based leadership, was performed. ⋯ The present study achieved its aims. First, it suggests the officers' character strengths that tend to be most valued by their subordinates among Czech Army cadets and soldiers serving in reconnaissance units. Second, the strong overlap of best officers' character profiles in all groups suggests that this perception may remain stable throughout a soldier's career. Third, the relationship between chosen officers' and respondents' self-reported strengths was negligible, suggesting that the perception of officer's strengths may not be an individual's projection. Fourth, regression models of character-based leadership proposed a combination of character strengths that may contribute to the officer's perceived efficacy. Compared to other studies, the sample included both cadets and military professionals with a proportional number of females being included. These results imply that health care practitioners working with military clients may benefit from the acknowledgment of their specific character strengths, most notably honesty and fairness, while providing care to this population.

The coronavirus disease 2019 (COVID-19) pandemic disrupted U.S. Military operations and potentially compounded the risk for adverse mental health outcomes by layering unique occupational stress on top of general restrictions, fears, and concerns. The objective of the current study was to characterize the prevalence of COVID-19 concerns and information needs, demographic disparities in these outcomes, and the degree to which COVID-19 concerns and information needs were associated with heightened risk for adverse mental health outcomes among U.S. Army soldiers. ⋯ COVID-19 concerns and information needs were prevalent and showed little evidence of decrement over the course of the first 6 months of the pandemic. COVID-19 concerns were consistently associated with adverse mental health outcomes. These data highlight two targets and potential demographic subgroups such that local leadership and Army medicine and public health enterprises can be better prepared to monitor and address to maintain force health and readiness in the face of possible future biomedical threats.

The leadership of Vista Forge 2022 requested evaluation of the handoff process between military assets and civilian emergency medical services (EMS) providers by the Beth Israel Deaconess Fellowship in Disaster Medicine (BIDMF). Vista Forge was a multi-agency military-civilian full-scale disaster exercise coordinated by the U.S. Military. The exercise, held in Atlanta, Georgia, simulated response to a nuclear bomb in an urban setting by military and civilian disaster teams. ⋯ Future studies should develop a standardized handoff procedure to be used in mass casualty situations, and trial it in future multi-agency disaster exercises. Radiation specific triage tags should be considered.
