For tactical reasons, the foot-borne soldiers sometimes undertake nighttime operations. However, the metabolic demand during walking in complete darkness may be markedly increased. The purpose of this study was to investigate if metabolic demand and kinematics would change while walking on a gravel road and a slightly hilly trail in darkness with or without visual aid. ⋯ Walking on a gravel road or a forest trail wearing a blindfold or visual aid increased the metabolic demand. Thus, it appears that the metabolic demand is higher during overground walking with night vision goggles than with full vision, which may influence the performance of nighttime operations.

Changes to severe acute respiratory syndrome 2 (SARS-CoV-2) vaccine guidance since their initial authorization may lead to confusion and hesitancy. Suggested recommendations for an annual SARS-CoV-2 vaccine naturally draw comparisons with the influenza vaccine program. Considering viral and vaccine characteristics between these pathogens provides an important perspective that can help increase vaccine confidence with SARS-CoV-2 vaccines.

Psychological problems and family maltreatment are significant public health problems. Although research focuses almost exclusively on either individual psychological problems or family maltreatment, there is substantial co-occurrence of these problems. Similarly, intervention services are often "siloed": individuals with mental health needs are referred for mental health services, individuals with family conflict are referred for family-based treatment, etc. These treatment "silos" may miss the larger picture of the co-occurrence of risk, promotion, and the problems themselves. In a previous paper, we used latent class analysis to identify subgroups of individuals with crosscutting patterns (i.e., classes) of psychological and family maltreatment problems. In this study, we explored the predictors of these latent classes. ⋯ These findings reinforce the need for integrated prevention and treatment of psychological and family maltreatment problems. Not only do these problems often co-occur, but their risk and promotive factors also tend to be intertwined. The unique (i.e., not on the continuum of the other five classes) problem profile of participants evidencing disinhibitory psychopathology is matched by a unique risk/promotive factor profile, and they will thus likely require a unique intervention approach.

The Brazilian Air Force (BAF) personnel must be prepared to perform their professional activities under the worst conditions. This preparation goes beyond habits of practicing physical activity, since it is necessary to perform specific physical tasks, referred to as "combat tasks" (CTs). This study aimed to investigate a combination of specific physical tests (SPTs) for predicting physical performance on simulated tasks (STs) that mimicked the performance of CTs. ⋯ In conclusion, this study identified a test battery for predicting performance on the following STs: foot march, casualty drag, and move under direct fire. This finding represents the first step to improve the reliability of the BAF physical assessments, focusing on combat readiness levels.

Mental health treatment is a service for military service members who have experienced psychological injury or trauma. Unfortunately, the stigma associated with treatment can prevent many service members from seeking and receiving treatment designed to help them recover. Previous studies have examined the impacts of stigma among military personnel as well as civilians; however, stigma among service members currently receiving mental health treatment is unknown. The purpose of this study is to understand the relationships between stigma, demographic variables, and mental health symptoms in a sample of active duty service members receiving mental health services in a partial hospitalization program. ⋯ In this active duty military cohort, greater mental health stigma was associated with greater severity of mental health symptoms, especially post-traumatic stress symptoms. Some evidence found that ethnicity may also play a role in stigma score differences, particularly in the Asian/Pacific Islander group. Service providers could consider assessing mental health stigma to meet the clinical needs of their patients within the context of their willingness to obtain and adhere to treatment. Anti-stigma efforts to reduce stigma and its impacts on mental health are discussed. Additional research investigating the effect stigma has on treatment outcomes would help guide the relative importance of assessing stigma, in addition to other behavioral health realms.
