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.

Mediastinal masses are a rare finding in the emergency department and typically present with vague chest complaints such as chest discomfort, chest pain, or dyspnea. Rarely do these tumors present with dysrhythmias, and when dysrhythmias are present, they typically arise secondary to endocrine or metabolic effects exerted by the tumor. Here we report a case of a patient who presented to the emergency department with atrial fibrillation with rapid ventricular response, concomitant with a history of recurrent palpitations that were previously aborted with self-induced vagal maneuvers. Upon further investigation, the patient had an anterior mediastinal mass, diagnosed as a thymoma, suspected to be contributing to his presenting dysrhythmia through mass effect.

The decision to enter the Navy as a physician is a major career choice. However, there are no published studies that address the typical Navy physician's experience in the Health Professions Scholarship Program (HPSP) and Uniformed Services University of the Health Sciences (USUHS) programs. The purpose of this qualitative study is to describe the typical Navy physician's experience in the HPSP and USUHS programs. ⋯ The principal findings in this study are that most Navy physicians favored paid medical school/financial support, working overseas and in unique operational climates, having unique life experiences, leadership skills, and prior military experience put them ahead of their civilian colleagues, thought the Navy experience was worth it, and would join again if given the opportunity. However, most Navy physicians had a lack of career control due to needs of the Navy, lack of knowledge regarding residency selection, operational billets, and active duty service obligation, had more difficulty getting into a military residency of their choice versus civilians, and had interrupted residency training/training delays. The Navy would possibly benefit from a nationwide HPSP/USUHS physician mentorship program and an educational seminar to increase medical student applicant knowledge, which may improve recruiting and retention.

Physical fitness is foundational to the U.S. Army as a component of combat readiness, and accurate assessment of readiness is imperative for mission success and soldiers' health and safety. To this end, the Army has developed the Army Combat Fitness Test (ACFT), which more accurately assesses these abilities and may aid development of a more combat-ready force. Reserve Officer Training Corps (ROTC) programs nationwide are often challenged by limited structured training time, as well as access to equipment and training space. Development and/or adaptation of a training program that addresses these limitations would benefit ROTC programs nationally. Therefore, the purpose of this study was to compare a standard military fitness training program to High-Intensity Functional Training (HIFT) in ROTC cadets. We hypothesized that a HIFT program would be more effective than the standard military program developed by the DoD on both ACFT performance and assessment of common Warrior Tasks and Battle Drills (WTBDs). ⋯ Three 60-minute sessions per week of moderate-high-intensity training elicited improvements in ACFT scores, with no statistically significant differences between training programs. For this population of ROTC cadets, implementing a structured training program with expert oversight appears to be effective. Based on the successes and unanticipated challenges encountered in this study, training programs that emphasize intensity, train a wide variety of movements, maximize adherence, and are adaptable to a variety of situations are likely to be successful at improving ACFT scores.

Exertional heatstroke (EHS) is defined as a disturbance in consciousness, ranging from confusion to coma, with hyperthermia typically higher than 40 °C that occurs during intense physical activity. It is a life-threatening pathology that has been observed in the military since antiquity. Recent research has changed the understanding of the pathophysiology of EHS and led to the development of gold-standard treatment, which includes intrarectal temperature monitoring and cooling the patient as quickly as possible. The objective of this study was to describe the theoretical knowledge of French military unit practitioners regarding the latest recommendations for the treatment of EHS and their management of this condition in practice. ⋯ French military practitioners' theoretical knowledge of EHS is insufficient for a lethal pathology that is common in the military. Thus, improvements must be made in training and disseminating up-to-date knowledge. In practice, a lack of adequate logistics and the fact that first responders are rarely practitioners increase the suboptimal care of EHS. First responders should be equipped with valid and adapted protocols and adequate logistical means to manage this condition. By establishing a cohort of well-treated patients, we will be able to develop evidence-based recommendations for when to cease cooling and identify intrinsic susceptibility to EHS.
