ABSTRACT
OBJECTIVE: Aim: To study the peculiarities of maintaining a healthy lifestyle by service members under martial law. PATIENTS AND METHODS: Materials and Methods: The research was conducted in 2022-2024 and involved 60 service members aged 22 to 54. According to their military rank, the respondents were divided into the following groups: junior enlisted (51.7 %), non-commissioned officers (25 %) and commissioned officers (23.3 %). Methods: bibliographic, system analysis and generalization, medical and sociological (questionnaire survey), and statistical. RESULTS: Results: It was found that a healthy lifestyle for most service members is associated with motor activities (51.7 %), rational nutrition (55.9 %), the ability to cope with stress (42.4 %), and giving up bad habits (37.3 %). Only 46.7 % of service members adhere to the relevant principles, even though 55.0 % of respondents named a HLS as one of the values in their unit. It was found that it is difficult to fully adhere to the principles of a healthy lifestyle under the conditions of war. 76.7 % of service members have bad habits (the most common is smoking - 72.2 %). CONCLUSION: Conclusions: Promising means of forming a healthy lifestyle for service members are: positive motivation and personal conviction in the need to maintain a healthy lifestyle, high-quality medical care, conducting educational work with personnel about the benefits of leading a healthy lifestyle, etc. However, these measures will become fully effective only if we end the war with victory and liberate all Ukrainian lands from the occupying forces.

BACKGROUND: Studies on oral health status of adults are sparse and rarely include data on endodontic treatment and trauma. In the military, those data are available because recruits are routinely assessed with a clinical and radiological examination at the start of their career. This study aimed to identify differences in oral health status of Dutch Armed Forces recruits between cohorts, departments, sex, age and rank, with DMF-T, endodontic treatment and dental trauma as outcome measures. METHODS: Data from Electronic Patient Files from all recruits enlisted in 2000, 2010 and 2020 were used for analysis in a hurdle model resulting in the estimated cohort effect, controlled for the demographic variables. The total number of recruits was 5,764. Due to the retrospective character of the study a proxy was used to compose D-T and dental trauma. RESULTS: The mean DMF-T number in recruits decreases from 5.3 in cohort 2000 to 4.13 in cohort 2010 and 3.41 in cohort 2020. The percentage of endodontically treated teeth increases from 6% in cohort 2000 to respectively 9% in 2010 and 8% in 2020. The percentage of recruits showing signs of dental trauma did not change significantly between cohort 2000 (3.1%) and cohort 2010 and 2020 (both 2.7%). CONCLUSIONS: Oral health in Armed Forces recruits is improving over the years, following a similar trend as the general population in the Netherlands. Lower SES represented by enlisted rank showed substantial lower oral health status.

BACKGROUND: The positive changes in hygienic living conditions are commonly believed to explain secular changes in body height and the age of maturity. However, it is difficult to estimate the separate impacts of these factors due to the lack of social and economic data and variations in the sources of information. We hypothesized that final male body height could be associated with various socioeconomic indicators, such as the development of the medical care system, the quality of nutrition, and the level of sanitary and hygienic conditions. Moreover, we hypothesized that male body height could be associated with the level of morbidity in the region during the time of conscript childhood (from 1 to 7 years old). MATERIALS AND METHODS: We used two main sources of information in the analyses. The first is the data from the Statistical Reference Book published by the Central Statistical Committee in 1929. The second is the annual data from the Statistical Reference Book published in the Russian Empire. Since the conscripts were born between 1906 and 1909, we used datasets from 1910 to 1913. To analyze the data, we used a method of analyzing interacting variables called St. Nicolas House Analysis (SNHA). RESULTS: Our analyses revealed direct associations between the morbidity of some diseases and male body height and other anthropometric parameters. CONCLUSIONS: There are associations between conscript final body height and the morbidity of influenza, dysentery and some venereal diseases, such as chancroid and syphilis. There were no associations between conscript final body height and the level of morbidity during childhood. However, other final parameters, such as BMI, weight, and chest circumference, could be associated with the morbidity of malaria, scabies, scurvy, and scarlet fever during childhood. The prevalence of these diseases could be strongly connected with unfavorable living conditions. The results are similar for both urban and rural areas.

BACKGROUND: Problematic anger, characterized by excessive frequency, intensity, and duration of anger which causes substantial emotional distress and functional interference, poses a marked challenge in military populations. Despite its importance, research on this topic is limited. This study contributes to the literature by exploring problematic anger in a large sample of Norwegian military personnel who served in NATO missions in Afghanistan. METHODS: All Norwegian military personnel who deployed to Afghanistan between 2001 and 2020 were sent a link to a cross-sectional web-based survey by the Joint Medical Services of the Norwegian Armed Forces in 2020. A total of 6205 individuals (response rate: 67.7%) participated. The cross-sectional survey assessed problematic anger, mental and physical health, war zone stressor exposure, and quality of life. RESULTS: Overall, 8.4% of participants reported problematic anger. Mental health disorders, deployment-related shame and guilt, chronic pain, and challenges with the military-to-civilian transition were independently associated with problematic anger. Both staying in service and maintaining a part-time connection with the military as a reservist mitigated the risk of problematic anger after deployment, compared to complete separation from military service. CONCLUSION: Findings demonstrate a sizeable prevalence of problematic anger among veterans of combat deployments. Given the associations between problematic anger and mental health disorders, chronic pain, and transition challenges, interventions designed to mitigate problematic anger need to be multi-faceted, including the possibility of maintaining an ongoing connection to military service. By reducing the risk of problematic anger, occupational, interpersonal and health outcomes may be improved for service members. Future research should examine the impact of problematic anger on adjustment over time, prevention strategies, and problematic anger in other high-risk occupations.

INTRODUCTION: Pilots are frequently exposed to thrombotic risk as a result of immobility from air travel. As hypoxemia is associated with secondary polycythemia, and polycythemia increases the risk of thrombosis, intermittent exposure to high-altitude hypoxic environments could escalate the risk of thrombosis in pilots. Our objectives were to find the prevalence of polycythemia in airplane pilots (primary outcome) and to assess associated risk factors of polycythemia (secondary outcome).METHODS: This study is a cross-sectional descriptive study. Data was collected from paper-based and computerized medical records of airplane pilots who applied for Class 1 Aviation Medical Certificate renewal at the Institute of Aviation Medicine, Royal Thai Air Force, Bangkok, Thailand, in 2018. The data was sampled by a simple random sampling technique.RESULTS: A total of 386 paper-based records were sampled. Of those, 29 (7.5%) of the pilots met polycythemia criteria. Spearman's correlation analysis showed a significant positive correlation between Body Mass Index (BMI) and hemoglobin (correlation coefficient = 0.127) and between BMI and hematocrit (correlation coefficient = 0.105). In multivariate logistic regression of each variable on polycythemia as defined by hemoglobin alone, piloting a non-pressurized aircraft was found to be an independent predictor of polycythemia (odds ratio = 4.3).DISCUSSION: The prevalence of polycythemia in airplane pilots was 7.5%. Operating a non-pressurized aircraft was a significant risk factor of polycythemia, and pilots with higher BMI were more likely to have increased red blood cell parameters.Thanapaisan P, Plaingam M, Manyanont S.

INTRODUCTION: Military aviation poses unique occupational risks, including exposures to intermittent hypoxia, high gravitational force, and toxic materials, in addition to circadian disruption, cosmic radiation, and ergonomic stressors also present in commercial flight. We sought to investigate whether a military aviation officer's career is associated with adverse maternal or fetal health outcomes.METHODS: We conducted a retrospective cohort study of female aviation and nonaviation officers in the Military Health System from October 2002 to December 2019. Exposure was identified as assignment of an aviation occupation code. Maternal and fetal health outcomes were identified by International Classification of Diseases codes from medical records. Regression analysis was used to estimate adjusted relative risks (aRR).RESULTS: Included in the study were 25,929 active-duty female officers, with 46,323 recorded pregnancies and 32,853 recorded deliveries; 2131 pregnancies were diagnosed in aviation officers. Pregnant aviation officers had a decreased risk of composite adverse pregnancy outcomes [aRR 0.82 (0.73-0.92)], including gestational diabetes [aRR 0.69 (0.57-0.85)] and gestational hypertension [aRR 0.84 (0.71-0.99)]. Pregnant aviation officers had a decreased risk of depression prior to delivery [aRR 0.43 (0.35-0.53)] and hyperemesis gravidarum [aRR 0.74 (0.57-0.96)], but an increased risk of placental complications [aRR 1.15 (1.02-1.30)] and fetal growth restriction [aRR 1.36 (1.16-1.60)].DISCUSSION: Pregnant military aviation officers have an increased risk of placental complications and fetal growth restriction in spite of a lower risk of gestational diabetes and gestational hypertension. Further research is needed to determine how flight-related occupations impact pregnancy.Stark CM, Sorensen IS, Royall M, Dorr M, Brown J, Dobson N, Salzman S, Susi A, Hisle-Gorman E, Huggins BH, Nylund CM.

BACKGROUND: The COVID-19 pandemic disrupted the daily life and routines of Americans across the United States (U.S.), including those of our active-duty service members (ADSMs). Limited movement orders enacted during this time to promote social distancing prohibited access to fitness and dining facilities for ADSMs. This study aims to expand on previous work identifying changes in body mass index (BMI) among U.S. Army service members by identifying changes in body mass index (BMI) among active-duty service members from both the Navy and Marine Corps during the same time period. METHODS: We conducted a retrospective cohort study of active-duty service members from the Navy and Marine Corps using data from the Military Health System Data Repository. BMI was calculated and categorized according to CDC guidelines both before (February 2019 - January 2020) and during the pandemic (September 2020 - June 2021). Women who were pregnant or delivered during and one year prior to the study periods were excluded. Statistical analyses included paired t-tests evaluating mean BMI, percent change, and the Stuart-Maxwell test for marginal homogeneity. RESULTS: We identified 98,330 active-duty Sailors and 55,298 active-duty Marines for inclusion in this study. During the pandemic period the percentage of Sailors with Underweight decreased by 11%, Healthy weight decreased by 11.1%, Overweight increased by 2.1%, and the percentage of Sailors with Obesity increased by 16.5%. During this same time period, Marines with Underweight decreased by 1%, Healthy weight decreased by 16%, Overweight increased by 3.0%, and Marines with Obesity increased by 51%. The largest increases in service members with overweight and obesity observed among both cohorts were among female service members, service members under age 20, and service members with a Junior Enlisted rank. CONCLUSIONS: Significant increases in obesity were observed amongst active-duty United States Navy and Marine Corps service members during DoD pandemic mitigation efforts. Increased rates of obesity likely effected fitness and force readiness. Future interventions should be targeted at younger, Junior-Enlisted Marines and Sailors to promote healthy lifestyles and provide education on nutrition, appropriate exercise, sleep hygiene, and stress management.

INTRODUCTION: We evaluated the risk factors associated with gastrointestinal disorders (GD) among the soldiers of the Army and Marine Aviation community (AMAC) using an exposomic approach. Specifically, we aimed to determine the medical and operational factors associated with reported GD in the Military Health System. METHODS: Longitudinal data were obtained from the Medical Assessment and Readiness System (MARS) housed at Womack Army Medical Center, Fort Liberty, NC, for a retrospective cohort study that included 79,249 active duty United States AMAC active duty service members (ADSMs) from October 2015 to December 2019. Multivariable mixed-effects logistic regression was used to assess the relationship between the incidence occurrence of GD and variables including rank, service time, deployment, Armed Forces Qualification Test score, education, tobacco use, alcohol use, age, gender, race, ethnicity, body mass index (BMI), and marital status. RESULTS: The incidence of GD included 22,813 person-years of observations with a rate of 2.2 per 100 person-years and a period prevalence of 3.2%. GD was independently associated with rank, service time, and deployment (all P < 0.05). CONCLUSION: The high-risk categories associated with GD in the AMAC included age, BMI, race (not ethnicity), marital status, and service time. Our data also show that deployment time, not geographical location, was associated with a higher risk of GD. Together, these analyses suggest that White ADSMs older than 33 years of age who have experienced marriage, longer service time, and deployments appear to have a higher risk of GDs. Our assessment shows the utility of using an exposomic approach to create a member-specific, big data-informed personalized clinical algorithm of health outcomes.

INTRODUCTION: Suicide is a prevalent problem impacting the military community. The U.S. Army recognized the need to address this complex issue; one line of effort has been to provide suicide prevention and intervention education and training that is informed by current research, doctrine, and implementation best practices. The purpose of this article is to outline and present the genesis of the Army's new suicide prevention and intervention training-"Ask, Care, Escort (ACE) Base +1"-that aligns with the DoD newly published regulation-driven initiatives. MATERIALS AND METHODS: The development of the "ACE Base +1" curriculum was a collaborative effort between two organizations within the Defense Health Agency: The Defense Centers for Public Health-Aberdeen and the WRAIR. A multidisciplinary team was formed by selecting specific operational and subject-matter experts from each organization based on educational qualifications and practical experiences expected to aid the development of curriculum content (e.g., subject-matter experts) and/or the training design. Revisions to the curriculum were informed by the Army's existing suicide prevention training module, current research in suicide prevention and public health, updated and relevant Army regulations, and current public health policy guidance from the CDC and the Department of Suicide Prevention Office. A detailed account of the systematic and iterative curriculum development process is provided. RESULTS AND CONCLUSIONS: The interagency collaborative efforts resulted in a suite of training products, "ACE Base +1" version 1.3 that is modernized in training content, delivery methods, and design. Four primary elements shaped the final products: (1) A modular framework allowing a tailored approach to mandatory training, (2) a public-health approach that focuses on earlier intervention opportunities while building trust and cohesion, (3) a training design centered on peer discussions and behavioral rehearsal, and (4) an expansion of the curriculum to be inclusive of the entire Army community. Practical implications for each element are discussed.As the program of record, "ACE Base +1" training satisfies the annual requirement for all Active Army, Army National Guard, U.S. Army Reserve, and Department of the Army (DA) civilians. Both the training content (e.g., public-health concepts) and design of "ACE Base +1" reflect a comprehensive approach, focused on developing concrete, applicable skills that support the shared responsibility to suicide prevention and intervention. Limitations, such as delayed interagency collaboration and time constraints, are discussed. Future directions include recommendations for future curriculum projects, specifically within military populations, such as interprofessional, interagency collaboration, and selecting a multidisciplinary team of subject-matter experts. Additionally, WRAIR plans to continue their support to Directorate of Prevention, Resilience and Readiness with the expansion of the +1 menu of trainings, ongoing program evaluation, and longitudinal analysis to inform future revisions and ensure the content and delivery methods remain modernized, relevant, and effective.

INTRODUCTION: Obstructive sleep apnea (OSA) is a treatable cause of daytime sleepiness and associated medical problems that can negatively impact soldier readiness and performance. This study examined adherence to positive airway pressure (PAP) by soldiers who were newly diagnosed with OSA and prescribed PAP therapy and participated in a Knowledge, Skills, and Attitudes (KSA) behavioral intervention class. MATERIALS AND METHODS: The KSA was a one-time, interactive 90-minute class attended by up to 10 patients per class. PAP adherence was examined using Medicare standard at 30-, 60-, 90-, and 180 days post class. The analytic sample comprised 379 active duty patients (93% men; mean age 40.21 ± 8.06) categorized into 3 groups: KSA (n = 235), did not show (DNS; n = 61), and mandatory education class (MEC; n = 83). The MEC group comprised patients from an education class in a previous year. RESULTS: Baseline scores on the apnea hypopnea index, body mass index, sleepiness, insomnia severity, and age were non-significant among the 3 groups. At 30 days, significantly more patients in KSA (48%) and MEC (51%) were adherent than the DNS group (16%). At 60 days, the adherence rates for the KSA, DNS, and MEC were significantly different at 39%, 22%, and 27%, respectively. At 90- and 180 days, the adherence rates among the KSA, DNS, and MEC groups did not differ significantly at 34%, 17%, and 26% (90 days) and 34%, 27%, and 25% (180 days), respectively. Consistently, more patients in KSA were adherent than those in DNS and MEC, except at 30 days. Additionally, adherence rates for KSA intervention declined more gradually over the 6 month period. The mean PAP usage on nights used was 4.6 hours that computed to a 34% non-use rate based on an optimal 7-hour/night sleep time. CONCLUSION: KSA could be a behavioral intervention that enhances PAP adherence with a booster session implemented at the 90 days mark.

INTRODUCTION: The association between hypothermia, coagulopathy, and acidosis in trauma is well described. Hypothermia mitigation starts in the prehospital setting; however, it is often a secondary focus after other life-saving interventions. The deployed environment further compounds the problem due to prolonged evacuation times in rotary wing aircraft, resource limitations, and competing priorities. This analysis evaluates hypothermia in combat casualties and the relationship to resuscitation strategy with blood products. METHODS: Using the data from the Department of Defense Joint Trauma Registry from 2003 to 2021, a retrospective analysis was conducted on adult trauma patients. Inclusion criteria was arrival at the first military treatment facility (MTF) hypothermic (<95ºF). Study variables included: mortality, year, demographics, battle vs non-battle injury, mechanism, theater of operation, vitals, and labs. Subgroup analysis was performed on severely injured (15 < ISS < 75) hypothermic trauma patients resuscitated with whole blood (WB) vs only component therapy. RESULTS: Of the 69,364 patients included, 908 (1.3%) arrived hypothermic; the vast majority of whom (N = 847, 93.3%) arrived mildly hypothermic (90-94.9°F). Overall mortality rate was 14.8%. Rates of hypothermia varied by year from 0.7% in 2003 to 3.9% in 2014 (P <0.005). On subgroup analysis, mortality rates were similar between patients resuscitated with WB vs only component therapy; though base deficit values were higher in the WB cohort (-10 vs -6, P < 0.001). CONCLUSION: Despite nearly 20 years of combat operations, hypothermia continues to be a challenge in military trauma and is associated with a high mortality rate. Mortality was similar between hypothermic trauma patients resuscitated with WB vs component therapy, despite greater physiologic derangements on arrival in patients who received WB. As the military has the potential to conduct missions in environments where the risk of hypothermia is high, further research into hypothermia mitigation techniques and resuscitation strategies in the deployed setting is warranted.

INTRODUCTION: Military medical evacuations (MEDEVACs) are resource intensive and can disrupt operations and decrease readiness. Medical evacuations are a concern for the submarine force because of the limited medical resources onboard, the impact of manpower loss on smaller crews, and the compromise of operational stealth. Although some medical emergencies cannot be avoided, some MEDEVACs may be preventable. However, there is limited knowledge of the underlying causes and risk factors associated with submarine MEDEVACs. This work describes an approach to identify individual characteristics associated with submarine MEDEVACs by presenting preliminary results and next steps. Identifying those most at risk for a MEDEVAC will foster prevention strategies that lead to fewer MEDEVACs, military operation disruptions, missed work and limited duty days, unplanned losses, early separations, and disability compensation claims among navy submariners. MATERIALS AND METHODS: This retrospective study examines MEDEVACs from U.S. Navy submarines from January 1, 2012 to December 31, 2020. Medical evacuation causes were classified by 3 major diagnostic categories: Injury, psychiatric, and medical (i.e., all other non-injury medical events, including dental issues). Diagnostic subcategories were grouped by body region (for injuries) and body system (for non-injuries). Identifiable information from MEDEVAC records were linked to personnel files to capture demographic and occupational variables. Trends across the years were examined, and frequencies and percentages of MEDEVAC cases by both major and sub-diagnostic categories were presented. For cases where both the major diagnostic categories and characteristics were both available, we assessed associations between major diagnostic categories and demographic and occupational characteristics, using Pearson's χ2 test for proportions and Fisher Freeman-Halton exact tests. Pairwise z-tests for proportions were used to determine which proportions differed significantly. RESULTS: A total of 1,283 MEDEVACs were confirmed from 2012 to 2020, with an annual average of 143. Across the years, 24.3% were caused by psychiatric issues (e.g., suicidal ideation), 18.4% were caused by injuries (e.g., blunt trauma), and the remaining 57.3% were caused by other medical emergencies (e.g., gastrointestinal issues). Among the cases linked to personnel files, the major diagnostic category was associated with age, rank, department, and submarine qualification status (group size varied). By age (n = 973), large differences in MEDEVAC causes were seen among submariners 21 to 25 years old who represented 52.4% of psychiatric versus 37.5% of medical MEDEVACs. In contrast, those 35 and older represented 17.0% medical versus 2.7% psychiatric MEDEVACs. CONCLUSIONS: Medical, non-injury cases were the most common cause for a MEDEVAC. There were proportionately more psychiatric than medical cases among younger, less experienced submariners. Conversely, there were proportionately more medical than psychiatric cases among older submariners. A centralized approach to collecting MEDEVAC data is needed. This is the most comprehensive study examining risk factors associated with submarine MEDEVACs. Follow-on work will include adding prior medical waiver requests, health indicators, and confirmed diagnoses to the dataset to conduct a risk analysis. Considering submarines have smaller crews than most surface ships, limited medical assets, and often operate in austere environments, examination of submarine MEDEVACs should be distinct from other navy and military MEDEVACs.

INTRODUCTION: Department of the Air Force basic military training (BMT) is the 7.5-week initial entry training for all enlisting U.S. Air Force and Space Force recruits. Overuse musculoskeletal injuries (MSKI) during training threaten success in BMT, and trainees with nutritional deficiencies are at higher risk. Several efforts are made at BMT to mitigate these issues to help trainees graduate on time, such as the distribution of multivitamins (MVI) to female recruits. However, trainee compliance with the prescribed MVI has been reported to be low, calling into question the effectiveness of this intervention. This study evaluated the effect of briefing modality offered to these trainees at the time of distribution on educational effectiveness, MVI compliance, and injury rates. MATERIALS AND METHODS: This was a randomized controlled cohort study of BMT female trainees. Subjects included all female trainees of a single iteration of BMT concurrently completing training within the same squadron. At the outset of training, cohorts were randomly educated in one of two ways regarding the provided MVI. The control cohort (n = 80) was presented with the standard educational video created by BMT-registered dietitians, while the test cohort (n = 79) was presented the video and then also briefed in-person by a group of subject matter experts. At the end of BMT, the trainees completed a questionnaire regarding their knowledge, confidence, and compliance with the MVI. Additionally, a routinely collected training database was queried and analyzed for differences in injuries and training outcomes using the chi-squared test with significance set to α ≤ 0.05. RESULTS: Although both cohorts found their educational presentation useful, the "in-person" cohort reported significantly higher compliance rates and were found to be diagnosed with MSKI and bone stress injuries at significantly lower rates (43% and 66% relative risk reductions, respectively). CONCLUSIONS: Education to female BMT trainees regarding the MVI, which included a face-to-face discussion with subject matter experts, resulted in greater compliance and reduced incidence of MSKI and bone stress injury, compared to a video prepared by registered dietitians alone. Such educational approaches should continue to be strived for in this and other military population health measures. This study's implication of MVI efficacy for injury risk reduction in female trainees should be further studied, verified, and improved upon in this and other populations.

INTRODUCTION: Musculoskeletal injuries (MSIs) are a leading cause of separation from the U.S. Navy. Data have shown that several psychological responses to MSI are associated with treatment outcomes. Yellow flags are maladaptive psychological responses to injury and predict delayed recovery, whereas pink flags indicate resilience after MSI and are associated with good treatment outcomes. Identifying these factors in patients with MSI would permit early targeted care to address factors that may delay their readiness for deployment and enhance factors that support recovery. MATERIALS AND METHODS: Active duty service members with MSI who reported to physical therapy outpatient services at a naval hospital were recruited for the study. Yellow flags were assessed at baseline as part of a larger study. Participants completed the Fear Avoidance Beliefs Questionnaire (with two subscales, physical activity and work), the Pain Catastrophizing Scale, and the Hospital Anxiety and Depression Scale. Clinically relevant cut-off scores were used to indicate risk factors of delayed recovery. Pink flags were assessed with the Pain Self-Efficacy Questionnaire and a measure of positive outcome expectations for recovery. RESULTS: Two hundred and ninety participants responded to some or all of the questionnaires. Of these, 82% exceeded the cut-off scores on the physical activity subscale of the Fear Avoidance Beliefs Questionnaire, and 39% did so on the work subscale. Pain catastrophizing exceeded the cut-off in only 4.9% of the sample. Forty-three percent of these exceeded the cut-off for the anxiety subscale of the Hospital Anxiety and Depression Scale; 27% exceeded the cut-off on the depression subscale of the Hospital Anxiety and Depression Scale. Additionally, 54% endorsed scores greater than 40 on the Pain Self-Efficacy Questionnaire, and 53% endorsed a high score on the positive outcome expectations. CONCLUSIONS: A substantial portion of the sample endorsed elevated scores on one or more indicators of delayed recovery from MSI. Most participants showed a fear of physical activity, and approximately half reported pain-related distress (anxiety and depression). In addition, feelings of self-efficacy and positive outcome expectations of treatment were endorsed by only about half of the participants, indicating that the remaining half did not report adaptive responses to MSI. Early identification of these risk factors will allow for targeted treatment approaches that incorporate these yellow flags into treatment and support a psychologically informed approach to physical therapy. This approach is likely to reduce delayed recovery and improve deployment readiness.

INTRODUCTION: Musculoskeletal injuries (MSKIs) among active duty soldiers result in more than 10 million limited duty days each year and account for more than 70% of the medically nondeployable population. Overuse injuries in lower limbs from running, foot marching long distances with heavy loads, and lifting heavy objects are the most common types of injuries in the military. Physical training and rehabilitation exercises for greater resiliency through aerobic, muscle strength, endurance, and agility conditioning programs can prevent or reduce the effects of MSKIs if Soldiers adhere to proper biomechanics and training techniques. We are introducing a three-dimensional (3D) camera-based platform for Optical Screening and Conditioning for Injury Resilience (OSCIR) that is designed to identify and correct high-risk movement patterns based on quantifiable biomechanical measurements in clinical or field settings. Our goal is to improve resilience to MSKI by offering greater access to quality of movement skills in warfighters through an autonomous device that can be used in Sports Medicine and Reconditioning Team (SMART) clinics and High-Intensity Tactical Training (HITT) sites. MATERIALS AND METHODS: OSCIR fuses four pairs of Kinect Azure cameras into a concise footprint to achieve suitable sampling rates and an unobstructed field of view for accurate dynamic movement tracking using a custom point cloud solution. We designed a unique multistage 3D joint tracking algorithm architecture to methodically isolate the human body point cloud from the background, identify individual limb segments, and perform iterative joint optimization at the global and local joint levels. We evaluated the feasibility of our prototype system among N = 12 control participants (6 M/6 F; 21-37 years) in compliance with the Western Institutional Review Board (Tracking #20225920, approved on November 4, 2022). Five task-specific MSKI outcome metrics identified by end-user physical therapists and athletic trainers as indicators for movement quality were assessed across 7 lower-extremity exercises derived from standardized MSK assessment/conditioning batteries used in the military. Data were recorded concurrently by OSCIR and a reference standard Vicon motion capture system for validating system accuracy. RESULTS: Task-specific MSKI indicators for knee flexion and hip flexion range of motion achieved an average error of 4.05 ± 2.34°, while 3D position-based postural outcomes of left-right foot distance, left-right hand distance, and step length obtained mean absolute errors of 2.58 ± 2.30 cm. Results support the feasibility of our system in achieving outcomes that are comparable to currently accepted laboratory standards. CONCLUSIONS: Our study describes the integration process for a 3D camera-based clinical system for MSKI conditioning and rehabilitation. The impact of our system will enable key stakeholders in the military to manage MSKIs in warfighters by automating key assessment and rehabilitation test batteries; making tests more readily accessible, and interpretations more accurate by providing objective biomechanical measures. OSCIR is undergoing turn-key design features to serve as a screening tool for warfighters to readily assess susceptibility to MSKI or as a training platform to help guide exercise techniques to achieve resiliency against future injuries.

INTRODUCTION: Comorbidities such as hypertension, diabetes mellitus, asthma, and cardiovascular conditions have been reported to worsen the clinical progression of coronavirus disease 2019 (COVID-19) and related hospitalizations. Furthermore, the COVID-19 pandemic has disproportionately affected the historically marginalized groups, i.e., Black, Hispanic, and Asian individuals have substantially higher rates of Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) infection, COVID-19 hospitalization, and death compared to White individuals. Despite these findings in civilian populations, the impact of comorbidities and race in SARS-CoV-2 infection and COVID-19 hospitalizations in military populations is unknown. We evaluated the relationship of pre-selected pre-pandemic comorbidities and race with SARS-CoV-2 infections and COVID-19 hospitalizations in U.S. military service members (SMs). MATERIALS AND METHODS: We conducted a systematic review of Military Health System beneficiaries' records by accessing the Defense Medical Epidemiological Database. Our inclusion criteria were being an active duty SM and having at least one pre-COVID-19 pandemic comorbidity. Retired as well as uninfected healthy active duty SMs and beneficiaries were excluded from the study. A total population of 1.334 million active duty SM records was drawn from Defense Medical Epidemiological Database. The data were stratified, by race (primary outcome), as well as gender, age, and military service branches (secondary outcomes). RESULTS: We found higher trends in SARS-CoV-2 infection and COVID-19 hospitalization rates in Black compared to White SMs. This seamless inequality was also seen in other viral infections affecting SMs including human immunodeficiency virus and viral hepatitis. We hypothesized this disparity to some extent be associated with the presence of pre-pandemic comorbidities that is affecting this military subpopulation. Supporting our hypothesis, we found trends toward the higher pre-pandemic prevalence of diabetes mellitus, asthma, hypertension, and ischemic heart disease, in Black compared to White military SMs, especially in Black older male adults. CONCLUSION: Our results highlight the role of pre-pandemic comorbidities and race likely enhancing the frequency of SARS-CoV-2 infections and COVID-19 hospitalizations in military SMs. These preliminary findings underscore the need for future retrospective studies using additional Military Health System data bases reporting data on this military subpopulation, especially in the setting of future pathogens outbreaks or pandemics affecting military populations.

INTRODUCTION: The Office of the Secretary of Defense and each of the services have made an unprecedented commitment to the prevention of sexual assault and related behavioral health phenomena. Indeed, the Department of Air Force has selected, in some cases tailored, and disseminated a wide array of evidence-based preventative programs, policies, and practices (EBPs) over the last few decades. However, many of these efforts seem to follow a predictable life course. EBPs are initially implemented with great enthusiasm, supported for a few years, then fall out of favor, and are replaced by a different effort. This research effort aims to build on the existing civilian implementation science research to (1) offer a military-specific model of sustained, high-quality implementation and (2) test this model in a series of interconnected studies. MATERIALS AND METHODS: New York University's Institutional Review Board approved the study protocols, and the Army's Human Research Protection Office provided permission to collect data. We conducted interviews first with prevention leaders in the services and at the Office of the Secretary of Defense level regarding factors that they thought helped or hurt the sustainment of EBPs. We used these interviews to identify EBPs currently implemented in Department of Air Force and selected four EBPs out of the 25 identified for intensive study. We then interviewed implementers of those four EBPs regarding what they thought helped or hurt the sustainment of that EBP. We also gathered information about the 25 currently implemented EBPs themselves and gathered policy and guidance, as well as leadership communication about those EBPs and the target problems they focus on. We coded this information to allow us to test EBP parameters and policy and leader communication that predict sustained high-quality implementation. We conducted over 100 observations of the 4 EBPs we are studying intensively and have collected quantitative data from implementers and participants to help us test factors related to sustained high-quality implementation within each of those 4 EBPs and across the EBPs. RESULTS: Several military-specific factors were nominated for inclusion in the military-specific model of implementation sustainment. The implementation of even highly standardized EBPs varies greatly. Implementers and participants are generally highly engaged, but implementers vary in the extent to which they understand the mechanisms of action for the EBP they are implementing. CONCLUSIONS: We recommend training implementers in the mechanisms of action in the EBPs they are expected to implement and including quality assurance as a component of prevention efforts in a manner more similar to how the military addresses aspects of the operational mission. By moving beyond counting classes and attendance, and specifying how to engage participants in the EBPs in the manner that produces the key outcomes, it is likely that EBPs will have more robust implementations that can be better sustained over time.

INTRODUCTION: 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. METHODS: To delve into the hazing climate and reporting culture at Fort Bragg, now Fort Liberty, 227 individuals took part in an anonymous online survey. The survey collected demographics and insights on hazing attitudes and behaviors, perceptions of group experiences including hazing/non-hazing activities, views on leadership, familiarity and experiences with reporting procedures, and bystander intervention. RESULTS: The findings echoed existing literature: while only 17.2% admitted to experiencing hazing, a striking 70.3% acknowledged involvement in specific hazing behaviors. Only 40% of participants who acknowledged experiencing hazing (n = 35) disclosed that they reported or confided in someone about the incident. Responses highlight reporting hurdles including concerns about anonymity, confidence in the reporting process, leadership reactions to reports, and the normalization of these events as tradition. DISCUSSION: 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.

INTRODUCTION: Military service members (SMs) with mild traumatic brain injury (mTBI or concussion) frequently report cognitive and behavioral difficulties. Currently, military clinical guidelines recommend clinician-run, manualized cognitive rehabilitation (CR) to treat these symptoms; however, it is unclear whether this approach adequately addresses the unique needs of warfighters. Computerized cognitive training (CCT) programs represent an innovative, promising approach to treating cognitive difficulties; however, whether these programs can effectively remediate cognitive impairment in individuals with mTBI remains unclear. MATERIALS AND METHODS: A total of 65 SMs with a history of at least 1 diagnosed mTBI were recruited from a military hospital. Participants received 1 of 2 interventions: Clinician-run, manualized CR (Study of Cognitive Rehabilitation Effectiveness [SCORE]; n = 37), consisting of 60 total intervention hours over 6 weeks, or CCT (n = 28), in which participants trained with either a commercial CCT (n = 14) or noncommercial CCT (n = 14), for a total of 12 hours over 4 weeks. Participants were assessed pre- and postintervention, using a combination of self-report and objective outcome measures: Key Behaviors Change Inventory (KBCI), a self-report measure of functional difficulties; Paced Auditory Serial Addition Test (PASAT), an objective cognitive assessment that measures both information processing speed and sustained and divided attention; and Symbol Digit Modalities Test (SDMT), an objective cognitive assessment that measures information processing speed. RESULTS: Mixed ANOVA revealed no interaction effect between intervention type and time (pre- and postassessment) on the PASAT (P = .643, ηp2 = 0.003), SDMT (P = .423, ηp2 = 0.010), or KBCI (P = .434, ηp2 = 0.010); however, there was a significant within-group main effect (time) on all 3 outcome measures (PASAT P < .001, ηp2 = 0.54; SDMT P < .001, ηp2 = 0.25; and KBCI P = .001, ηp2 = 0.15). On average, participants showed improvement over baseline on the PASAT (SCORE delta = 6.98, SD = 7.25, P < .001; CCT delta = 7.79, SD = 6.45, P < .001), SDMT (SCORE delta = 4.62, SD = 8.82, P = .003; CCT delta = 6.58, SD = 10.81, P = .003), and KBCI (SCORE delta = -3.22, SD = 7.09, P = .009; CCT delta = -2.00, SD = 4.72, P = .033). Additional analysis comparing the relative effectiveness of the 2 different CCTs revealed that while training with either program resulted in improved performance on the PASAT (P < .001, ηp2 = 0.627), SDMT (P = .003, ηp2 = 0.286), and KBCI (P = .036, ηp2 = 0.158), there was no interaction effect of CCT program type and change over time for any measure (PASAT P = .102, ηp2 = 1.00; SDMT P = .317, ηp2 = 0.038; and KBCI P = .719, ηp2 = 0.005). CONCLUSIONS: We showed that CCT programs do not differ in efficacy compared to clinician-run, manualized CR for treating symptoms associated with mTBI; however, exploratory analyses suggest that each approach may have distinct advantages for treating specific symptoms. Additionally, we showed that the improvement in the CCT intervention did not differ between those who trained using the commercial program vs. those who trained with the noncommercial program.

INTRODUCTION: Sleep-related disorders are associated with pain, fatigue, and deficits in cognitive performance, which may interfere with successful rehabilitation. The study objectives were to (1) quantify outpatient prescriptions for insomnia medications during the first year following combat-related amputations, (2) examine longitudinal changes in prescriptions for insomnia medications, and (3) analyze patient characteristics associated with prescriptions for insomnia medications. MATERIAL AND METHODS: This was a retrospective study of DoD casualty records from the Expeditionary Medical Encounter Dataset and prescriptions for outpatient medications from the Pharmacy Data Transaction Service. Patients were a total of 1,651 U.S. service members who sustained major limb amputations in Operations Iraqi and Enduring Freedom from 2001 through 2017 and had outpatient prescriptions for any medication during the first year postinjury. Prescriptions for medications recommended for insomnia were low-dose antidepressants, anxiolytic sedatives, benzodiazepines, melatonin receptor agonist, and low-dose quetiapine. These prescription medications were analyzed by medication type, postinjury time, and patient characteristics during the first year postinjury. RESULTS: During the first year postinjury, 78% of patients (1,291 of 1,651) had outpatient prescriptions for insomnia medications, primarily anxiolytic sedative drugs (e.g., zolpidem), averaging a total of 86 prescription days (median = 66). The prevalence of these prescriptions declined substantially during the first year, from 57% of patients during the first quarter to 28% during the fourth quarter postinjury. In univariate analyses, multiple patient characteristics, including high Injury Severity Score, continued opioid and non-opioid analgesic prescriptions, and diagnoses of chronic pain, mood disorder, and posttraumatic stress disorder, were significantly associated with higher prevalence and duration of outpatient prescriptions for insomnia medications. CONCLUSIONS: The present results indicate a high prevalence of outpatient prescriptions for insomnia medications following combat-related amputations, a prevalence that is substantially higher than previously reported among active duty personnel. These findings can inform DVA/DoD guidelines for amputation care and insomnia among military subpopulations. The results highlight the need for more research on the treatment of insomnia during early postinjury rehabilitation among patients who sustained serious combat injuries.
