In military training settings, stress can improve focus and motivation fostering effective learning. However, high perceived stress can be debilitating resulting in poor learning and clinical errors. Multiple studies have focused on medical residency stress; but there has been minimal focus on dental residents and even less on the impact of the unique stressors from the COVID-19 pandemic. The objectives of this study were to determine the impact of the COVID-19 pandemic on perceived stress of residents in a military dental residency training program and explore the association among perceived stress and anxiety, depression, sleep quality, and social support. ⋯ Based on pre-pandemic perceived stress, participants responded differently to the impact of the pandemic shutdown. The low baseline stress participants may have a more robust sense of grit and resilience. These findings suggest that postgraduate dental training programs should integrate coping skills training opportunities, especially for residents reporting high perceived stress before residency.

In this article, I present my views on the diversified approaches to assess the physical fitness of soldiers within selected armies worldwide. I discussed the related common features and paradoxes associated with these approaches. For the comparative analysis, national diversity was taken into account and subjective selection of the physical fitness tests conducted in the armies of the United States, Finland, Germany, India, China, Israel, Netherlands, Sweden, Switzerland, United Kingdom, and Poland was done. ⋯ In conclusion, I am in favor of multi-system tests, comprised of obstacle courses mirroring potential situations in combat tasks. In my opinion, multi-system tests are superior compared to single-system function tests since they enable a comprehensive assessment of effort, coordination, and mental predispositions necessary for functioning in real-life conditions. I also support physical fitness evaluation that is not differentiated based on a soldier's gender and age, as there is no logical justification for such distinctions.

Acute respiratory distress syndrome (ARDS) is a widespread and often fatal clinical syndrome marked by the acute onset of pulmonary edema and inflammatory-mediated disruptions in alveolar-capillary permeability resulting in impaired gas exchange and tissue oxygenation with subsequent acute respiratory failure that accounts for 10.4% of all intensive care unit admissions worldwide and boasts a mortality rate of 38.5%. The current treatment for ARDS remains largely supportive. This is largely because of the many challenges of achieving a stable and sustainable animal model that recreates the pathophysiology of ARDS experimentally in a controlled setting to allow research to elucidate potential treatments of ARDS moving forward. ⋯ In conclusion, we demonstrated a viable animal model of human ARDS that is maintained for a prolonged period, suitable for continuous monitoring of the progression, and evaluation of potential future treatments and procedures to reduce patient morbidity and mortality. To carry out this two-hit model, lung injury was induced through a combination of bronchoalveolar lavage and oleic acid administration and the disease process of ARDS is subsequently tracked through clinically relevant parameters such as respiratory mechanics, cytokine response, aretrial blood gas (ABG) changes, and observation of postmortem histopathologic changes. This promising new model has the capacity to successfully replicate human ARDS which is a well-known and notoriously multifactorial pathogenic process to reproduce experimentally for an extended period of time. The "two-hit model" is a viable and appropriate model for the research of novel treatments for ARDS.

The U.S. Military members experiencing combat-related injuries have a higher chance of developing infections by multidrug-resistant (MDR) bacteria at admission to military hospitals. MDR wound infections result in higher amputation rates and greater risks for subsequent or chronic infections that require readmission or extended stay in the hospital. Currently, there is no FDA-clear, deployable early diagnostic system for suitable field use.We are reporting our efforts to improve a previously developed Rapid Label-free Pathogen Identification (RAPID) system to detect viable MDR bacteria in wound infections and perform antibiotic susceptibility testing (AST). Specifically, we added multiplex and automation capability and significantly simplified the sample preparation process. A functional prototype of the improved system was built, and its performance was validated using a variety of lab-prepared spiked samples and real-world samples. ⋯ Our system has achieved excellent performance in detecting viable bacteria presence and in performing AST in a multiplex, automated, and easy-to-operate manner, on both lab-prepared and real samples. Our results have shown a path forward to a rapid (sample-to-answer time ≤3 hours), accurate, sensitive, species-specific, and portable system to detect the presence of MDR combat-related wound infections in the field environment. Our future efforts involve ruggedizing the RAPID system and evaluating performance under relevant environmental conditions.

Efficacy of 1% Clotrimazole Powder Monotherapy for Treating Tinea Cruris: A Comparative Randomized Study.
A rise in tinea cruris among Thai Naval Cadets has been observed. Clotrimazole powder has been shown to be effective as an adjunct treatment for tinea cruris; however, its efficacy as a monotherapy is limited. ⋯ Monotherapy with 1% clotrimazole powder showed comparable efficacy to 1% clotrimazole cream. Furthermore, the powder treatment reduced sweat more effectively compared to the cream.
