Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccines are a remarkable scientific achievement. The perspective on past viral vaccine performance and viral characteristics, such as incubation period, can help with messaging and instilling vaccine confidence. Protection against mild infection occurs in the short term (months), but the persistence of protection against severe disease will likely endure longer.

One of the main avoidable causes of combat-related injury death is extremity hemorrhage. Even with regular training, failure to properly apply a tourniquet is common. In this study, we sought to assess if rescuer's stress and personality traits, along with victim's state of consciousness, had a role to explain tourniquet application failure. ⋯ Combat-related injuries, even simulated, not only involve the rescuer's technical skills but also their ability to deal with stressful external stimuli. Tourniquet application speed seems to be influenced by perceived stress and personality traits of the rescuers. Frequent failures justify repeated training, and one way to pursue improvement could be to develop a personalized pedagogy adapting to the needs of the students according to their current skillset but also their perceived stress and personality determinants. In the pedagogical process (planning, goal setting, teaching, and evaluating), the state of consciousness of the victim seems to be a parameter that needs to be accounted for, but further studies are required to accurately describe its influence.

The Effectiveness of a Standardized Ice-Sheet Cooling Method Following Exertional Hyperthermia.
Exertional heat illnesses remain a major threat to military service members in the United States and around the world. Exertional heat stroke (EHS) is the most severe heat illness, characterized by core hyperthermia and central nervous system dysfunction. Per current Army regulations, iced-sheet cooling (ISC) is the recommended immediate treatment for heat casualties in the field, but concerns have been raised regarding the efficacy of this approach. Thus, the purpose of this study was to quantify the cooling rate of ISC following exertional hyperthermia. ⋯ ISC increases the cooling rate of those recovering from exertional hyperthermia. With the observed cooling rate, we can extrapolate that ISC would reduce core temperature by ∼2 °C within 30 minutes during a case of EHS. We conclude that ISC provides a safe and effective alternative for the field where cold water immersion resources may not be readily available.

Sleep disorders are common in the military, and there is a gross shortage of sleep specialists in the military health system. The purposes of the present study were to (1) understand perceptions and expectations surrounding sleep telehealth approaches and (2) solicit feedback to optimize and refine a proposed novel sleep telehealth management platform. To accomplish these objectives, we investigated the perceptions, expectations, and preferences of active duty service members (ADSMs) with sleep disorders, primary care managers (PCMs), and administrative stakeholders regarding sleep telehealth management. ⋯ The proposed sleep telehealth platform appealed to nearly all participants as a significant force multiplier to enhance sleep disorder management in the military. Stakeholders offered valuable recommendations to optimize the platform to ensure its successful real-world implementation.

The impact of deployment and combat on mental health of military personnel is well described. Less evidence is available to demonstrate and summarize the incidence, prevalence, and risks of these exposures on physical health. This study aims to (1) systematically review the available literature to determine the incidence and prevalence of physical health conditions among military personnel during and after deployment and (2) investigate the risks of deployment and combat exposure on physical health. ⋯ Given the characteristics of included studies and extracted data, the magnitude of the found differences in incidence and prevalence rates is most likely to be due to methodological heterogeneity. The specific exposures (e.g., infrastructure, environmental conditions, and activities during deployment) are suggested to be the determinants of (post) deployment physical health problems and need to be addressed to decrease the impact of deployment. Findings from this systematic review highlight which conditions should be addressed in response to service members' health and wellness needs in the (post)deployment phase and may be used by clinicians, researchers, and policy-makers. However, knowledge gaps regarding the potential risk factors during deployment and combat still exist. Studies using consistent methods to define and measure the physical health conditions and specific exposures are needed.
