Introduction: The fit of military clothing and equipment is essential for the health and safety of military operators. Given the aim of increasing the proportion of women and the known biological and morphological differences between male and female soldiers, an understanding of fit across different items of kit is needed. The aim of this study was to quantify subjective fit ratings of 8 items of military clothing and equipment, including combat shirt, combat pants, rucksack, small pack, tactical vest, fragmentation vest, helmet, and ballistic eyewear as a function of relative stature and occupational group among male and female Canadian Armed Forces members.
Materials and methods: An online survey was distributed to male and female Canadian Armed Forces members, where fit was reported by participants according to a 7-point Likert acceptability scale. Participants were binned into 1 of 6 (3 males, 3 females) standing stature categories based on percentiles in a male and female distribution that included (1) under 35th percentile stature, (2) 35th to 80th percentile stature, and (3) over 80th percentile stature. Additionally, participants were separated according to occupational group: Group A: Infantry, Combat Engineer, Artillery, Armored; group B: Signals, Medical Technician, Intelligence, Signals Intelligence/Cyber Ops; group C: Supply Technician, Weapons Technician, Vehicle Technician, Electronic-Optronic Technician, Ammunition Technician; other: Not in other groups, examples include: Financial Services Administrator, Cook. This study was approved by the Defence Research and Development Canada Human Research Ethics Committee under protocol 2019-048, Amendment 2.
Results: There were significant effects attributable to stature category and occupational group on the fit of equipment. Specifically, fit acceptability of the rucksack helmet, small pack, and tactical vest was significantly affected by occupational group. Differences between stature categories were detected in all items with the exception of the small pack.
Conclusions: Military equipment fit has previously been shown to have implications for protection, performance, and mobility. The results of the investigation demonstrate different patterns of fit acceptability in male and female soldiers across items of clothing and equipment and may require different solutions.
简介:军用服装和装备的合身性对军事人员的健康和安全至关重要。鉴于增加女兵比例的目标,以及男女士兵之间已知的生理和形态差异,需要了解不同装备的合身性。本研究的目的是量化加拿大武装部队男性和女性成员对 8 种军用服装和装备(包括作战衬衫、作战裤子、背包、小背包、战术背心、防弹背心、头盔和防弹眼镜)的主观合身性评分,并将其与相对身材和职业类别挂钩:我们向加拿大武装部队的男女成员发放了一份在线调查问卷,参与者根据 7 点李克特可接受性量表来报告是否适合自己。根据男性和女性分布中的百分位数,将参与者分为 6 个站立身材类别(3 男 3 女)中的 1 个,这些类别包括:(1)低于第 35 百分位数的身材;(2)第 35 至 80 百分位数的身材;以及(3)超过第 80 百分位数的身材。此外,还根据职业组别对参与者进行了分类:A 组:步兵、战斗工兵、炮兵、装甲兵;B 组:信号兵、医疗技术员、情报员、信号情报员/网络行动员;C 组:供应技术员、武器技术员:供应技术员、武器技术员、车辆技术员、电子-光电技术员、弹药技术员;其他:不属于其他组别,例如财务管理员、厨师。本研究获得了加拿大国防研究与发展部人类研究伦理委员会(Defence Research and Development Canada Human Research Ethics Committee)2019-048号协议第2修正案的批准:结果:身材类别和职业组别对装备的合身性有明显影响。具体来说,职业类别对背包头盔、小背包和战术背心的合身性有显著影响。除小背包外,所有装备在身材类别上都存在差异:军事装备的适配性先前已被证明对防护、性能和机动性有影响。调查结果表明,男性和女性士兵对不同服装和装备的合身性有不同的接受模式,可能需要不同的解决方案。

Introduction: Surgical volume at Military Treatment Facilities (MTFs) has been gradually decreasing for roughly the past 2 decades. The Knowledge, Skills, and Abilities (KSA) Clinical Readiness Program linked surgical volume and readiness using a tool known as the KSA metric. However, the extent to which military medical missions contribute to the readiness of critical wartime specialties has not been evaluated using this metric.
Methods: In this study, a retrospective analysis was conducted using the surgical case logs from the US Naval Ship (USNS) Comfort missions in 2018 and 2019. The comprehensive case log data were categorized by year, surgeon, procedure, and location. The analysis focused on providing detailed descriptive statistics, including percentages pertaining to the types of procedures performed during these missions. The 2018 mission was 11 weeks in duration, and supported activities in Ecuador, Peru, Colombia, and Honduras. The USNS Comfort mission in 2019 lasted 6 months (June-November 2019), and visited 12 countries in Central America, South America, and the Caribbean.
Results: The 2019 mission case log, spanning 6 months, was evaluated using the KSA score in order to assess readiness and compare against 6 months of MTF KSA values within the same calendar year. In 2019, the orthopedic surgeon aboard the USNS Comfort had a total KSA score of 44,006, but the 6-month USNS Comfort mission only contributed 5,364 points (12% of the annual score). The general surgery practice aboard the USNS Comfort produced lower KSA scores compared to each surgeon's respective MTF practice (Table III). Analyzing the cases logged by general surgeons also highlights minimal surgical diversity during these missions, with more than 90% of cases being hernia repairs or laparoscopic cholecystectomies (Table I). In addition, 35% of total procedures performed in 2018 and 2019 were performed laparoscopically.
Conclusions: The analysis of operative data from the 2019 USNS Comfort mission, in comparison with the surgeons' work at their respective MTFs, reveals limited benefit in the ability of hospital-ship missions to bolster surgical readiness as measured by the KSA score. However, this is not a reflection on the value of Global Health Engagement (GHE) itself but a review of the way in which it is leveraged to support surgical readiness. Military surgeons participate in GHE as part of a larger strategy to strengthen relationships with partner nations, improve military medical force interoperability, and bolster partner nation medical capacity and capabilities. The KSA score offers an excellent tool to compare readiness metrics across significantly different GHE missions, and facilitates the opportunity for future prospective studies to improve case volume, diversity, and ultimately readiness.

Introduction: The global rise in obesity is well-established, with significant health implications. This study aims to comprehensively assess overweight and obesity prevalence within the French Armed Forces.
Materials and methods: Using data from the Unique Medical-Military Software (UMMS) in 2018, a cross-sectional study was conducted on active French Military personnel aged 18 and above, who underwent periodic medical examinations (PME) in 2017. Body Mass Index (BMI) served as the main criterion for overweight and obesity classification. A representative sample was obtained through random sampling.
Results: The sample included 17,082 individuals, revealing an average age of 33.5 years, with 36.1% classified as overweight and 9.6% as obese. The mean BMI of women was significantly lower than that of men (23.9 vs 25.3 kg/m2-P < .001). Results indicated that 22.4% of women vs 38.5% of men were overweight (P < .001). For obesity, the difference was not significant (8.8% of women vs 9.8% of men-P = .138). BMI increased with age, and non-commissioned officers (NCOs) showed the highest prevalence of obesity. Gendarmes exhibited the highest BMI and overweight rates (50.1%) among military branches.
Conclusion: While obesity is less prevalent in the French Armed Forces compared to the general population, the study emphasizes the equivalent prevalence of overweight. We confirm here that the global epidemic of obesity and overweight affects all armed forces. France seems less affected than other Western armies. Targeting specific groups, such as NCOs and the national gendarmerie, is crucial for prevention.

Introduction: In military training settings, stress can improve focus and motivation fostering effective learning. However, high perceived stress can be debilitating resulting in poor learning and clinical errors. Multiple studies have focused on medical residency stress; but there has been minimal focus on dental residents and even less on the impact of the unique stressors from the COVID-19 pandemic. The objectives of this study were to determine the impact of the COVID-19 pandemic on perceived stress of residents in a military dental residency training program and explore the association among perceived stress and anxiety, depression, sleep quality, and social support.
Materials and methods: Dental residents (N = 20) at the Naval Postgraduate Dental School participated in this study. Residents were assessed via self-report measures quarterly from March 2020 through June 2021. The assessment included measures of anxiety (GAD-7), depression (PHQ-9), perceived stress (PSS), fatigue (FSI), and social support (DUKE-SSQ).
Results: Before the pandemic shutdown, 60% of participants reported high perceived stress. These residents reported an initial decrease in symptoms of anxiety, depression, and fatigue compared to residents reporting low pre-pandemic perceived stress but returned to baseline levels post-shutdown. Additionally, the high stress participants reported lower social support.
Conclusions: Based on pre-pandemic perceived stress, participants responded differently to the impact of the pandemic shutdown. The low baseline stress participants may have a more robust sense of grit and resilience. These findings suggest that postgraduate dental training programs should integrate coping skills training opportunities, especially for residents reporting high perceived stress before residency.

Introduction: A challenge confronting health care is the national physician shortage, notably impacting the DoD's recruitment of military physicians. To address this, the Health Professions Scholarship Program is annually awarded to medical students to facilitate their transition into the U.S. Armed Forces. There is a glaring absence of military medical education in civilian schools to accommodate the unique interests of these students. While medical schools have adapted with interest groups and specialty tracks, the current presence of military medicine interest groups (MMIGs) and military medicine specialty tracks (MMSTs) remains under-explored. This study aimed to (1) update the prevalence of MMIGs in U.S. medical institutions, (2) identify the presence of MMSTs, and (3) compare military medicine involvement between allopathic and osteopathic programs.
Methods: The study was approved for exempt status from the Kansas City University Institutional Review Board (study number 20,211,568-1). In a cross-sectional analysis, surveys were sent to 208 U.S. medical schools, with responses from student services or available public data from 200 institutions included in the final analysis. A secondary survey was sent to respondents who provided MMIG or MMST contacts.
Results: Results indicated that 62% (n = 124/200) of schools currently have an established MMIG, a modest growth from 56% (n = 70/125) in 2015 (p = .14). MMST prevalence, however, is minimal at 2.5% (5/200). Osteopathic institutions demonstrated a significantly greater engagement in military medicine education (88.7%) compared to allopathic schools (52.4%) (p < .001).
Conclusion: This research underscores the need for comprehensive military medical training in medical schools to meet the interests and career aspirations of their students. Future studies should also evaluate the efficacy of MMIGs and MMSTs in preparing students for military medical roles.

Mal de Débarquement Syndrome (MdDS) is a poorly understood vestibular disorder that frequently affects military personnel exposed to motion during transportation and deployment. It is characterized by a persistent sensation of motion often experienced after disembarking from a ship or other mode of transportation. It can significantly affect a service member's balance, coordination, attention, and focus, which can then substantially impact their quality of life, ability to perform their military duties, and overall mission readiness. Despite its potential impact, comprehensive studies on MdDS are scarce, especially within the military. The unique conditions of military service, including frequent travel, long flights, maritime deployments, and high-stress environments, make the military well suited to study MdDS. Increased awareness and understanding of MdDS is crucial for everyone in the military-from medical personnel responsible for the diagnosis and treatment of MdDS to commanders who must consider the operational impact of impaired personnel.

<p><strong>Introduction: </strong>The U.S. Military members experiencing combat-related injuries have a higher chance of developing infections by multidrug-resistant (MDR) bacteria at admission to military hospitals. MDR wound infections result in higher amputation rates and greater risks for subsequent or chronic infections that require readmission or extended stay in the hospital.

<p><strong>Introduction: </strong>Military service members (SMs) are exposed to repetitive head impacts (RHIs) in combat and training that are purported to adversely affect brain health, including cognition, behavior, and function. Researchers have reported that RHI from blast-related exposure may affect both vestibular and ocular function, which in turn may be related to symptomology. As such, an examination of the effects of RHI on exposed military SMs should incorporate these domains. To date, researchers have not compared groups of exposed special operations forces (SOF) operators on combined clinical vestibular/ocular and eye-tracker-based outcomes. Therefore, the primary purpose of this study was to compare participant-reported symptoms and performance on the Vestibular/Ocular Motor Screening (VOMS) tool with performance on the computerized RightEye tracking system between SOF operators exposed to blast-related RHI and healthy controls without blast-related exposure. In addition, the study aimed to compare subgroups of snipers and breachers exposed to RHI to controls on the preceding metrics, as well as identify a subset of individual (demographic) factors, participant-reported symptoms, and performance metrics on VOMS and RightEye that best identify SOF operators exposed to RHI from unexposed controls.</p><p><strong>Materials and methods: </strong>The study involved a cross-sectional design including 25 Canadian SOF SMs comprised of breachers (n = 9), snipers (n = 9), and healthy, unexposed controls (n = 7). The former 2 groups were combined into an RHI group (n = 18) and compared to controls (n = 7). Participants provided demographics and completed a self-reported concussion-related symptom report via the Military Acute Concussion Evaluation 2, the VOMS, and RightEye computerized eye-tracking assessments. Independent samples t-tests and ANOVAs were used to compare the groups on the outcomes, with receiver operating characteristic curve and area under the curve (AUC) analyses to identify predictors of blast exposure. This study was approved by the Defence Research Development Canada Human Research Ethics Committee and the Canadian Forces Surgeon General/Special Forces Command.</p><p><strong>Results: </strong>The results from t-tests supported group differences for age (P = .012), participant-reported symptoms (P = .006), and all VOMS items (P range = <.001-.02), with the RHI group being higher than healthy controls on all variables. ANOVA results supported group differences among snipers, breachers, and controls for age (P = .01), RightEye saccades (P = .04), participant-reported total symptom severity (P = .03), and VOMS total scores (P = .003). The results of the receiver operating characteristic curve analyses supported age (AUC = 0.81), Military Acute Concussion Evaluation 2 participant-reported total symptom severity (AUC = 0.87), and VOMS total scores (AUC = 0.92) as significant predictors of prior blast exposure.</p><p><strong>Concl
