Reserve Officers' Training Corps (ROTC) trainees are college students who complete military courses and participate in physical and tactical training under the direction of military Service Members assigned to ROTC programs to serve as faculty and staff at US colleges. ROTC trainees report musculoskeletal injuries (MSKIs) attributable to ROTC training in line with MSKI incidence in other training environments. However, concealment is prevalent, as 66% of MSKIs in ROTC go unreported. The current study investigated if a brief, online educational video could increase ROTC trainees' reporting intentions. In addition, we investigated if the message's source (i.e., peer or authority figure) affected reporting intentions. ⋯ Findings did not support the use of a single educational intervention video to influence MSKI help-seeking intentions of ROTC trainees. Intentions may already be ingrained such that a single intervention could not influence change. Previous research on concussion reporting indicates that concealment cultures may be systematic and indoctrination of concealment can influence one's reporting intentions. Our sample had already participated in ROTC for 2 years. Future research should evaluate if MSKI help-seeking intentions change over the course of ROTC participation, or even over a military career.

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.

The cervical spine, pivotal for mobility and overall body function, can be affected by cervical spondylosis, a major contributor to neural disorders. Prevalent in both general and military populations, especially among pilots, cervical spondylosis induces pain and limits spinal capabilities. Anterior Cervical Discectomy and Fusion (ACDF) surgery, proposed by Cloward in the 1950s, is a promising solution for restoring natural cervical curvature. The study objective was to investigate the impacts of ACDF implant design on postsurgical cervical biomechanics and neurorehabilitation outcomes by utilizing a biofield head-neck finite element (FE) platform that can facilitate scenario-specific perturbations of neck muscle activations. This study addresses the critical need to enhance computational models, specifically FE modeling, for ACDF implant design. ⋯ This study emphasized the use of a biofidelic head-neck model to assess ACDF implant designs. Our results indicated that including neck muscles and head structures improves biomechanical outcome measures. Furthermore, unlike Ti implants, our findings showed that PEEK implants maintain neck motion at the affected level and reduce disk stresses. Practitioners can use this information to enhance postsurgery outcomes and reduce the likelihood of secondary surgeries. Therefore, this study makes an important contribution to computational biomechanics and implant design domains by advancing computational modeling and theoretical knowledge on ACDF-spine interaction dynamics.

Future multidomain operational combat environments will require combat medics to play a larger role in managing behavioral health (BH) conditions in forward environments, as soldiers in small teams may have them as their sole medical support for extended periods of time. Previously they were not expected to serve in this role, and thus, they receive minimal BH training. It is unknown to what extent combat medics consider BH tasks as falling within their scope of practice and how often they engage with their soldiers currently related to BH. Qualitative research suggests that many medics feel inadequately prepared to handle BH problems. Our aim is to further assess medic attitudes and behaviors related to BH to better understand the landscape of medic preparedness to fill an expanded role. ⋯ Most medics agreed that numerous BH tasks fell within the scope of their work, but few felt confident engaging in those tasks. These findings support a need for additional training in BH-related tasks across the force. Exploring ways to provide medics BH-related work rotations would augment their general proficiency as first-line treatment providers for soldiers in combat units, and increased training in BH-related tasks should be studied to determine its ability to increase competency and confidence. If medics can learn to assess and recognize BH concerns before they escalate to needing specialty BH care, this could potentially reduce the burden on BH clinics, as well as strengthen the overall force.

As female active duty populations increase in all military environments, it is critical that women's health be addressed in a comprehensive manner. The study's results will be utilized to assist Navy health care leaders in addressing female force readiness policies, treatment gaps, and training specific to women's mental health. ⋯ This exploratory study highlights that provider variables impact assessment and treatment of and for patients. The study highlights the interplay of gender, treatment setting, experiences, and level of comfort are associated with provider assessment of presenting concerns. The authors hope this study will help in prioritizing women's mental health practices, mental health training, and research, and in informing policy and decision-making.
