Formal Methods for Establishing Simulation Interoperability for Military Health System Applications.
Advancements in information technology have facilitated information exchange practices within the Military Health System (MHS), enabling "systems of systems" approaches that broaden and coordinate the set of capabilities available to enhance patient outcomes. This is applicable for MHS modeling and simulation (M&S) applications as well. Learning from successful approaches applied in current interoperability solutions used in the military helps to ensure interoperability practices yield trusted compositions of simulations. ⋯ Biomedical research must contend with complexity inherent to computational human body modeling, enlisting expert knowledge from multiple domains supporting the development of cross-disciplinary research tools that resolve research foci and associated differences in underlying theories, methods, and applied tools. This is closely related to the broader context of digital engineering for military systems engineering.

The condition of trauma patients and the urgent need for timely resuscitation present unique challenges to trauma teams. These difficulties are exacerbated for military trauma teams in combat environments. Consequently, there is a need for continued improvement of nontechnical skills (NTS) training for trauma teams. However, current approaches to NTS assessment rely on subjective ratings, which can introduce bias. Accordingly, objective methods of NTS evaluation are needed. Eye-tracking (ET) methods have been applied to studying communication, situation awareness, and leadership in many health care settings, and could be applied to studying physicians' NTS during trauma situations. In this study, we aimed to assess the relationship between trauma team leaders' objective gaze patterns and subjective expert NTS ratings during patient care simulations. ⋯ This study utilized a mixed methods approach to assess trauma team leaders' NTS in simulated acute care trauma simulations. Our results provide several objective insights into trauma team leaders' NTS behaviors during patient care simulations. Such objective insights provide a more comprehensive understanding of NTS behaviors and can be leveraged to guide NTS training of trauma physicians in the future. More studies are needed to apply these methods to capture NTS from a larger sample of teams in both simulated and real trauma environments.

Auditory injuries induced by repeated exposures to blasts reduce the operational performance capability and the life quality of military personnel. The treatment for blast-induced progressive hearing damage is lacking. We have recently investigated the therapeutic function of liraglutide, a glucagon-like peptide-1 receptor agonist, to mitigate blast-induced hearing damage in the animal model of chinchilla, under different blast intensities, wearing earplugs (EPs) or not during blasts, and drug-treatment plan. The goal of this study was to investigate the therapeutical function of liraglutide by comparing the results obtained under different conditions. ⋯ This study indicated that the liraglutide mitigated the blast-induced auditory injuries. In EP ears, the pre-blast administration of liraglutide reduced the severity of blast-induced acute damage in ears with EP protection, especially under G2. In animals with open ears, the effect of liraglutide on the restoration of hearing increased with time. The liraglutide potentially benefits post-blast hearing through multiple approaches with different mechanics.

Addressing hazing within the U.S. Military has become a critical concern to safeguard the well-being of service members; recent attempts to assess hazing prevalence in the military have been unsuccessful due to under representative data. ⋯ Distinct elements of military culture, such as the hierarchical chain of command, loyalty to the brotherhood/sisterhood, and the emphasis on resilience, likely amplify these responses. This study adds to the mounting evidence showcasing gaps in assessing hazing within the U.S. Military. It emphasizes the necessity for a comprehensive hazing prevention program. Presently, prevention relies on mandatory training, often integrated into safety briefings or harassment workshops. However, service members require further assistance in recognizing, rejecting, and reporting instances of hazing despite these trainings.

Sternal intraosseous (IO) access has advantages over humeral and tibial access for fluid resuscitation in military medical settings due to superior flow rates and pharmacokinetics. However, the morphology of the young adult manubrial cortical and medullary bone as it relates to IO catheter tips of currently available FDA-approved IO access devices is unclear. ⋯ Present findings suggest that both FAST1 and TALON sternal IO catheter tips can be successfully placed into the target medullary bone with high accuracy in male military members aged 18 to 30 who require rapid resuscitation.
