Immediate evacuation of burn casualties can be challenging in austere environments, and it is predicted to be even more difficult in future multi-domain battlespaces against near-peer foes. Therefore, a need exists to treat burn wounds at the point of injury to protect the exposed injury for an extended period. In this study, we compare two commercially available FDA-approved therapies to the current gold standard of care (GSOC), excisional debridement followed by the application of split-thickness skin graft, and the standard for prolonged field care, silver sulfadiazine (SSD) cream. The shelf-stable therapies evaluated were irradiated human skin (IHS) allograft and polylactic acid (PLA). Our objective was to study whether they have the potential capability to reduce the need for evacuation to a burn center for surgical intervention so that the combat power can be preserved in the field. ⋯ This preclinical study demonstrated that the use of the PLA and the IHS dressings resulted in similar outcomes to the GSOC-treated burns in several key metrics of wound healing. These therapies represent a potentially useful tool in current and future battlespaces, where surgical intervention is not possible. The products are lightweight and, more importantly, stable at room temperature for their entire shelf lives. This would allow for easy storage and transport by medical practitioners in the field.

We tested the hypothesis that a carbohydrate (CHO: 6.5%) or carbohydrate-electrolyte (CHO + E: 6.5% + 50 mmol/L NaCl) drink would better recover plasma volume (PV) and exercise performance compared to water (H2O) after immersion diuresis. ⋯ Although CHO and CHO + E better restored PV after immersion, post-immersion exercise performance was not augmented compared to H2O, highlighting that fluid replacement following immersion diuresis should focus on restoring volume lost rather than fluid constituents.

Patient demographics, such as sex and age, are known risk factors for undergoing revision following primary total hip arthroplasty (THA). The military population is unique because of the increased rates of primary and secondary osteoarthritis of the hip. Treatment options are limited for returning patients to their line of duty; however, THA has been shown to be an effective option. The primary purpose of this study was to evaluate and contrast the demographic differences of patients undergoing primary THA between the U.S. active duty military population and the general population. The secondary goal was to identify the proportion of primary THA performed at the MTF within the military health system (MHS). ⋯ Patients in the MHS are undergoing THA at a younger age and are more likely to be male compared to the general population. A significant portion of primary THAs in the MHS are also being performed at civilian institutions. These demographics may result in increased risk of revision; however, long-term studies are warranted to evaluate survivorship in this unique population.

Impostor phenomenon (IP) is an experience where an individual believes that their success was because of chance or luck and was not associated with the mastery of skills. There is a gap in the literature in understanding what role, if any, onboarding (e.g., orientation weeks) into a military medical school plays into student experiences with IP. For many, onboarding serves as the first exposure to the climate, culture, and learning environment of both medical school and the military. Prevention, or early intervention, of IP may reduce potential effects on a medical trainee's confidence and competence in their profession, which may ultimately enhance health care team performance and impact patient outcomes. This study explores if and why military medical students experience IP during a 2-week-long orientation into a military medical school. ⋯ Our identified themes provide us with a better understanding of if and why military medical students experience IP during onboarding. Our findings are also consistent with the situated learning theory, which places emphasis on the sense of belonging and may provide a unique and insightful lens through which IP can be further explored and studied, particularly at a military medical school where various identities, dynamics, and aspirations can converge simultaneously. Additionally, our findings suggest that existing practices may benefit from a number of improvements including, but not limited to, tailoring onboarding activities to entail more reflective discussion using small groups, especially for topics related to diversity and inclusion, revisiting areas where students may feel inadequately prepared to transition and perform well in a medical school, reevaluating administrative and financial support that can be roadblocks to a student's transition into the new environment and removing these barriers, and ensuring cultural coherence (organizational alignment of vision and mission) among faculty, staff, and upperclassmen. Future research directions include better understanding how developing single or multiple, identities can impact a medical students' experience with IP during onboarding, pre-clerkship, clerkship, or post-clerkship period, if at all.

Insulin-like growth factor type I (IGF-I) has gained considerable notoriety in military training, primarily because it is responsible for energy deficits and sensitive to an inadequate protein intake, which are situations that are commonly experienced in specific military operations. Therefore, this study aimed to assess the kinetics of IGF-I and insulin-like growth factor binding protein type 3 (IGFBP-3) in a 4-day military field training exercise. ⋯ It can be concluded that IGF-I and IGFBP-3 levels respond quickly to the stimuli caused by military training, especially after specific field training. However, the same markers quickly return to their basal values after this type of training finishes, simply by following the daily routine of the battalion in the control weeks, with no specific intervention being necessary.
