Active duty flight crew plays a critical role in military operations. The occupational demands of the flying environment require a certain level of medical suitability. Additionally, such an environment could be more hazardous for certain populations. While the Centers for Disease Control and Prevention, the American Academy of Pediatrics, and the World Health Organization strongly support exclusive breastfeeding for the health benefit of both the mother and the child in the first 6 months of life, the aeromedical implications of lactating are not widely discussed. Breastfeeding is inherently challenging for many women, in part because of the frequent emptying required to maintain breastmilk supply and avoid complications such as engorgement, clogged ducts, and mastitis. This pilot study evaluated the experiences of individuals concurrently breastfeeding while on active duty Naval flying status to (1) assess whether these individuals experience frequent challenges or complications associated with lactating and (2) establish the need for future expanded studies. ⋯ This study hypothesizes that occupational demands associated with aviation result in a decreased ability to maintain exclusive breastfeeding, an increased risk for engorgement and clogged ducts, and a higher likelihood of early weaning among Naval aviators. It included only the perspectives of Naval officers, thereby lacking the input of enlisted aircrew on flight status, who comprise a large population of active duty flyers. The responses, although limited by a lack of controls and survey limitations, indicate that a future study to expand understanding of the aeromedical implications on lactating individuals would be valuable for improving workplace support and the ultimate success of lactating women in meeting their breastfeeding goals.

Metabolic Demands and Kinematics During Level Walking in Darkness With No Vision or With Visual Aid.
Uniformed services commonly perform foot-borne operations at night, while using visual aid in terms of night vision goggles (NVG). During slow-level walking, complete lack of visual input alters kinematics and markedly increases the metabolic demand, whereas the effect on kinematics and energy expenditure of restricting the peripheral visual field by wearing NVG is still unknown. The purpose was to evaluate whether metabolic demands and kinematics during level walking are affected by complete darkness with and without visual aid. ⋯ The study confirms that complete lack of visual cues markedly reduces the mechanical efficiency during level walking, even under obstacle-free and highly predictable conditions. That $\dot{\text{V}}$O2 and step length values for the NVG conditions fell in between those of the Light and Dark conditions suggest that both foveal and peripheral vision may play important roles in optimizing the mechanical efficiency during level walking.

Routinely faced with potentially traumatizing situations, resilience is critical for military physicians. However, related studies are limited in scope. The current study distinctively combines hyper-realistic immersion training for military medical students with emotional intelligence and hardiness measures. With self-reflection shown to improve performance, qualitative inquiry was concurrently conducted in a mixed methodology approach to provide a uniquely comprehensive perspective on the resilience training needs of this population. ⋯ This unique pilot study showed that quantitative and qualitative results aligned, supporting the finding that a safe trauma-related training environment can improve the confidence and resilience in military medical students. The goal of this training was to promote resilience and mitigate trauma. Results demonstrate improved self-efficacy and enhanced commitment. Increases in self-awareness and confidence made participants more inclined to see their worth and strengthened their sense of duty as described in their qualitative responses. Pervasive gains suggest that the training aligned well with its purpose, and the methods employed enhanced participant experience. Long-term follow-up studies are needed to assess outcome sustainability.

We report the case of a 37-year-old man presenting with pain out of proportion to the exam with hydrofluoric acid burns to his upper extremities after he spilled a wheel-stripping compound on his forearms while working at his powder coating business. His burns initially appeared mild and superficial, but over the course of several days, these evolved from simple erythema to significant partial thickness tissue destruction and ulceration. He required substantial topical, intradermal, and intravenous therapies to control the unseen burning process during his index visit to the emergency department. ⋯ Following nonoperative management, he had an uneventful recovery with full function retained in the affected extremities. Hydrofluoric acid burns require prompt treatment with calcium to neutralize the burning process, despite a potentially benign initial appearance. The emergency clinician should use an aggressive diagnostic and therapeutic approach to patients presenting with pain out of proportion to their exam, as this finding is associated with various serious underlying pathology.

High rates of physician burnout are well documented in the USA. Identifying beneficial leadership behaviors as an organizational approach to mitigating burnout can lead to improved wellness in the physicians that they lead; however, few studies have examined which leadership behaviors are beneficial and which may be detrimental. ⋯ Organizational interventions are needed to improve burnout in physicians. Adopting favorable leadership behaviors while avoiding unfavorable leadership behaviors can improve burnout in those physicians being led. These findings could inform the conceptual basis of future physician leadership training programs as transactional leadership behaviors also have an impact on physician wellness.
