Coronavirus disease 2019 (COVID-19) vaccine hesitancy is a major impediment to achieving herd immunity and overcoming the current pandemic. Our aim was to decrease the prevalence of vaccine hesitancy through an education intervention. ⋯ Our education intervention was effective in reducing COVID-19 vaccine hesitancy in a military base population. Study limitations include applications toward other military and non-military populations, the possibility of nonresponse bias, and absence of prior validated interventions. Area for future studies includes improvement upon educational intervention, development of other effective methods, and application of intervention in other populations.

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.

Hemorrhage is the leading threat to the survival of battlefield casualties. This study aims to investigate the types of fluids and blood products administered in prehospital trauma encounters to discover the effectiveness of Tactical Combat Casualty Care (TCCC) recommendations. ⋯ Changes in TCCC guidelines did not immediately translate into changes in prehospital fluid administration practices. Crystalloid fluids continue to dominate as the most commonly administered fluid even after the 2014 TCCC guidelines changed to use of blood products over crystalloids. There should be future studies to investigate the reasons for delay in guideline implementation and efforts to improve adherence.

Cases of multisystem inflammatory syndrome after current or previous SARS-CoV-2 infection have been extensively documented in children. Although there has been recent recognition of a similar adult post-COVID entity known as multisystem inflammatory syndrome in adults (MIS-A), these cases have rarely been reported. This report describes the case of a soldier in the deployed setting with a benign initial clinical presentation who rapidly developed life-threatening MIS-A.

Published guidelines on spirometry interpretation suggest an elevated FVC and FEV1 > 100% of predicted with an obstructive ratio may represent a physiological variant. Further evidence is needed on whether this finding indicates symptomatic airways obstruction and what additional evaluation should be done. ⋯ Normal FEV1 > 90% of predicted and obstructive indices may not represent a normal physiological variant in all patients. In symptomatic patients, a positive MCT and elevated baseline IOS values were more common than in asymptomatic patients with similar PFT characteristics. These findings suggest that clinicians should still evaluate for airway hyperresponsiveness in patients with exertional dyspnea with airway obstruction and FEV1 > 90% of predicted and consider alternative diagnoses to include a normal physiologic variant if non-reactive.
