Context: Exertional heat stroke (EHS) is the most deadly form the exertional heat illness with a higher incidence among active duty US military members than in the general population. Current guidelines on EHS recovery timelines and return to duty vary among the military branches. In some cases, individuals experience prolonged heat and exercise intolerance with repeat exertional heat illness events, which can complicate the recovery process. Management and rehabilitation of such individuals is unclear. Case Presentation: This manuscript addresses the case and management of a US Air Force Special Warfare trainee who experienced 2 episodes of EHS, despite early recognition, gold standard treatment, and undergoing 4 weeks of a stepwise recovery after an initial EHS. Management and Outcomes: After the second episode, a 3-step process was utilized, consisting of a prolonged and personalized recovery period, heat tolerance testing using Israeli Defense Force advanced modeling, and stepwise reacclimatization. This process allowed the trainee to successfully recover from repeat EHS and return to duty, and set a framework for future repeat EHS treatment guidelines. Conclusions: In individuals with repeat EHS, a prolonged recovery period followed by heat tolerance testing can be used to demonstrate appropriate thermotolerance and safely clear an individual to begin stepwise reacclimatization. Overall, patient care and military readiness may be improved by unified Department of Defense guidelines for return to duty after EHS. [ABSTRACT FROM AUTHOR]

Some leaders tend to use their intuition to think and make decisions more than others do. This individual difference (i.e., an intuitive cognitive style) may have important implications for the collectives of people they lead. Unfortunately, scholars lack a clear understanding of the conditions under which intuition is effective, especially in the context of large and complex organizational structures such as multiteam systems (MTSs). We argue that the effects of leaders' intuitive cognitive style on MTS performance depends on the amount of information load they face in their roles, as well as their level of introversion: a personality characteristic that is associated with an inward and reflective focus. Using a sample of 222 MTSs comprised of Captains in the United States Air Force, our study demonstrated that the intuitive cognitive style of leaders in high information load roles positively affected MTS performance, especially if they were high in introversion. In low information load roles, however, an intuitive cognitive style had a negative effect on MTS performance, especially for leaders low in introversion. We also argued and found that MTS coordination effectiveness played a key mediating role. Our study advances research in multiple areas of work, including intuition, MTSs, and leadership.

The interest in flying wings dates as far as the early years of the aviation age. Early investigations of the feasibility of the concept demonstrated increased aerodynamic efficiency and reduced fuel consumption. However, structural, engine integration, and stability and control issues prevented further development. In the 1990s, a new concept, the blended wing body (BWB), was created to alleviate some of the concerns of flying wings while maintaining increased efficiency and adding further benefits, such as reduced pollutant and noise emissions. Despite the promise, technical hurdles once again proved to be a deal breaker and, as of 2024, the only successful flying wing is the B-2 Spirit, an extremely complex and expensive aircraft. Nowadays, with the world quickly transitioning towards cleaner energy, the interest in the BWB has been renewed. The latest technological advancements in the aerospace industry should make its development more plausible; however, passenger comfort issues remain. Surprisingly, the BWB development may come from an unexpected application, as a tanker aircraft. As the U.S. Air Force is seeking a replacement to hundreds of aging tankers, a startup company was recently funded to develop the concept and build a prototype. In this study, we explore the history of blended designs from its early days, highlighting its opportunities and challenges—and why the design is an intriguing fit for application as a tanker aircraft.

U.S. service members are at an enhanced risk for developing mental disorders. To address these challenges, while promoting operational readiness and improving mental health outcomes, the Department of Defense directed each service component to develop and implement universal resilience enhancing programs. This paper provides a review of theoretical approaches conceptualizing resilience to trauma, including the theoretical foundations of programs currently in place. The resilience programs of U.S. Army, U.S. Air Force, U.S. Navy and U.S. Marine Corps are described, and available program effectiveness data are reviewed. Gaps between theory and practice are identified and an alternative method of assessing psychological readiness in Army units that is informed by resilience theory is offered as one way to address these gaps and scientific concerns. By comprehensively assessing the stressors affecting Soldiers at regular intervals, military leaders may be able to better identify and mitigate stressors in a systematic way that bolsters individual and unit psychological fitness. An enhanced psychological readiness metric stands to strengthen the validity of current resilience programs, bring clarity to the mechanisms of resilience, and provide a novel way for leaders to promote readiness in their units. Application of this metric within the infrastructure of existing reporting systems stands to improve mental health outcomes for Service Members, enhance the psychological readiness of the force, and reduce healthcare costs over time.

Introduction Military physicians must be prepared to lead health care teams across complex landscapes of war during future small- and large-scale combat operations. This preparation optimally begins in medical school so that early career physicians are fully ready for their first deployment. Past qualitative research has suggested that military physicians who attended civilian medical school are not as well prepared for the operational environment as physicians who attended the Uniformed Services University (USU), our nation's military medical school. However, there is a lack of larger-scale quantitative research comparing the readiness differences between the two medical school pathways. The purpose of this study, therefore, was to quantify any differences in first deployment preparation between students attending USU and civilian medical schools through the Health Professions Scholarship Program (HPSP). Materials and Methods We compared USU and HPSP graduates' first deployment experiences by distributing a 14-item Likert survey to active duty military physicians in the U.S. Army, U.S. Navy, and U.S. Air Force who graduated within the past 10 years from medical school (USU or civilian). Results The USU graduates rated themselves significantly higher than the HPSP graduates on their readiness for deployment (3.83 vs. 3.24; P  < .001); ability to navigate the operational environment (3.59 vs. 2.99; P  < .001); confidence in communicating with their commanding officer (3.59 vs. 2.99; P  = .002); navigating the combined role as physician and officer (3.33 vs. 2.84; P  = .004); leading a health care team (3.94 vs. 3.43; P  = .001); preparation by a medical school (3.78 vs. 2.52; P  < .001); and overall readiness compared to peers (4.20 vs. 3.49; P  < .001). There was no significant difference between the two pathways regarding their stress level at the beginning of deployment (2.74 vs. 2.68; P  = .683); clinical preparation (3.94 vs. 3.76; P  = .202); and success of first deployment (3.87 vs. 3.91; P  = .792). The largest effect size of the difference between the two pathways was noted on the question "How well did medical school prepare you for your first deployment" (Cohen's d  = 1.02). Conclusions While both groups believed that they were prepared for their first deployment, USU graduates consistently reported being more prepared by medical school for their first deployment than HPSP graduates. To close this readiness gap, supplemental military unique curricula may help to optimize HPSP students' readiness. [ABSTRACT FROM AUTHOR]

Introduction The U.S. Air Force's Intercontinental Ballistic Missile (ICBM) force stands ready to launch weapons 365 days per year. Since its inception, missileers vigilantly operate launch consoles on a 3-day cycle: minimum 24-hour alert-shift/24-hour travel-admin/24-hour off, leading to concerns that health, morale, and alertness are chronically impacted. In 2020, a Missileer Occupational Health Assessment (OHA) revealed 76% of respondents struggle with being rested for duty and 29% of respondents never feel adequately rested for duty. Later that year, 20th Air Force initiated long-duration operations to safeguard from the SARS CoV-2 (COVID-19) Pandemic, resulting in increased operations tempo, and exacerbating crew fatigue. 341st Operations Group and 341st Medical Group at Malmstrom Air Force Base enacted interventions to mitigate crew fatigue and support continued readiness during pandemic operations. They recorded, analyzed, and compiled findings in this report, including recommendations for long-term ICBM operations at Missile Wings. Materials and Methods All participants were Nuclear and Missile Operations Officers, or missileers, were continuously evaluated with qualitative and quantitative measures to ensure safety of the force during a period of unprecedented change. Interventions implemented and evaluated during the 9-month period included: environmental modifications, scheduling changes, and crew education on fatigue management, nutrition, anticipatory sleep preparation, and fitness. Most notably, the 341st Operations Group examined various 3-person and 4-person shift-length and alert duration schedules. Psychomotor vigilance testing results validated safety of operators and delta between pre- and post-shift measurements. Crew force readiness trends were analyzed for force-health awareness. Pre- and post-OHA results were compared for subjective changes. Fatigue and health-related outcomes were collected from a safety monitoring effort during standard and COVID-19 operations at 341st Missile Wing. Results Findings from qualitative and quantitative data indicate the optimal schedule is a 3-week cycle: 7-day alert/7-day recovery/7-day training-administrative utilizing 4-member or 3-member crews for low tempo operations. Crews experimented with shift-lengths of 24hrs-on/24hrs-off, 16hrs-on/8hrs-off, and 12hrs-on/12hrs-off. Maximum safe alert duration is 7 days due to task fatigue onset between 8 and 10 days. Short and long duration Duties Not to Include Flight (DNIF) (also known as Duties Not to Include Alert (DNIA) among missileers) rates decreased from the first to last month of the period by 74.6% and 79.2%, respectively. The number of alerts missed per month decreased 86% from baseline. The 2021 OHA found a 7% decline in members seeking separation, and absence of sleep, fatigue, and physical or mental health as missileer concerns. Conclusions This analysis has identified a sustainable alert rotation of 7/7/7 with emphasis on protected recovery and training time and has been continued after concluding pandemic operations, creating consistent schedule stability where there once was none. If executed properly, this alert rotation, regardless of shift-length selected, has potential to improve trust between crews and leadership, provides adequate recovery time between alerts to maintain health, and improves wellness, family stability, morale, unit cohesion, and crew force retention. Notably, all Air Force Global Strike Missile Operations Groups adjusted scheduling practices to align with these findings. [ABSTRACT FROM AUTHOR]

There are no published studies on pregnancy-related concerns, worries, and fears (CWFs) in primiparous and multiparous women and men in U.S. Air Force (USAF) families. Reflecting a biopsychosocial model of behavioral health, women's and men's pregnancy-related CWF Questionnaires were developed. Usable data were obtained from 260 women and 243 men in USAF families. Similarities and differences in pregnancy-related CWFs were found when USAF and general population data were compared. The present findings can inform not only the general provision of pregnancy health-related services but also USAF secondary prevention pregnancy-related programs (e.g., USAF nurse home visiting programs for first-time parents). If CWF Questionnaires are individually administered, the information can be used to tailor services to individual client needs. [ABSTRACT FROM AUTHOR]
