RESUMEN
Cold weather operations are logistically difficult to orchestrate and extremely challenging for soldiers. Decades of research and empirical evidence indicate that humans are extremely vulnerable to cold and that individual responses are highly variable. In this context, it may be necessary to develop personalised strategies to sustain soldiers' performance and ensure overall mission success in the cold. Systematic cold weather training is essential for soldiers to best prepare to operate during, and recover from, cold weather operations. The purpose of this review is to highlight key aspects of cold weather training, including (1) human responses to cold, (2) nutrition, (3) sleep and (4) protective equipment requirements. Bringing science to practice to improve training principles can facilitate soldiers performing safely and effectively in the cold. Cold weather training prepares soldiers for operations in cold, harsh environments. However, decreases in physical, psychological and thermoregulatory performance have been reported following such training, which influences operational ability and increases the overall risk of injuries. When optimising the planning of field training exercises or operational missions, it is important to understand the soldiers' physical and cognitive performance capacity, as well as their capacity to cope and recover during and after the exercise or mission. Even though the body is fully recovered in terms of body composition or hormonal concentrations, physical or cognitive performance can still be unrecovered. When overlooked, symptoms of overtraining and risk of injury may increase, decreasing operational readiness.
RESUMEN
Background: Post-traumatic stress disorder (PTSD) is one of the most common mental health problems that military personnel encounter. It could be lifelong and affect every aspect of military personnel, including their mental and physical health, family and social interactions, and their work. However, in Ethiopia, the magnitude and its associated factors have not been well investigated. Objective: This study aimed to determine the prevalence of PTSD and its associated factors among military personnel, who were admitted at the Northwest Command Level Three Military Hospital, Bahir Dar, Northwest, Ethiopia, 2022. Methods: An institution-based cross-sectional study was conducted from 21 June to 21 July 2022, at the Northwest Command Level Three Military Hospital. A computer-generated simple random sampling technique was used to select a total of 627 participants. The 17-item Military Version Checklist was utilized to measure PTSD. The Patient Health Questionnaire, Brief Resilience Coping, and Critical War Zone Experience scale were utilized to measure depression, resilience, and combat exposure, respectively. Descriptive, bivariate, and multivariate binary logistic regressions with odds ratios and a 95% confidence interval were used. The level of significance of the association was determined at a p-value < 0.05. Results: A total of 612 respondents participated, with a response rate of 97.6%. The prevalence of PTSD in this study was 21.9% (95% CI: 18.6, 25.2). In multivariable regression, female sex [adjusted odds ratio (AOR) = 2.3, 95% CI; 1.3, 3.87], combat personnel (AOR = 2.75, 95% CI; 1.44, 6.36), handling dead bodies (AOR = 2.5, 95% CI,1.24, 5.02), having 4-5 deployments (AOR = 2.94, 95% CI, 1.63, 5.32), having ≥6 deployments (AOR = 3.4, 95% CI, 1.95, 6.17), low resilience coping (AOR = 2.02, 95% CI; 1.16, 3.53), poor social support (AOR = 2.46, 95% CI, 1.39, 4.35), very high combat exposures (AOR = 4.8, 95% CI, 2.03, 11.93), and depression (AOR = 2.8, 95% CI, 1.68, 4.67) were significantly associated with PTSD. Conclusion: PTSD is markedly prevalent among the Ethiopian military population, with key risk factors identified as being female, poor social support, low resilience coping skills, handling dead bodies, multiple deployments (four or more), high combat experiences, and depression. Healthcare professionals must prioritize the early diagnosis and intervention of PTSD in vulnerable groups of military personnel.
RESUMEN
BACKGROUND: Neurorehabilitation in military populations is complicated by higher rates of PTSD and unique characteristics of military institutions. These factors can adversely impact the patient-therapist therapeutic alliance and engagement with the rehabilitation process leading to poorer outcomes. MDMA is a non-classical psychedelic with pro-social and fear regulating properties. MDMA-assisted therapy is being explored as a novel treatment for PTSD that potentially offers rapid symptom improvement and enhances therapeutic alliance. OBJECTIVE: A review of MDMA-assisted therapy for PTSD is provided in the context of neurorehabilitation in military populations. The molecular mechanism of MDMA is outlined and a novel application of MDMA for neurorehabilitation is proposed. METHODS: This is an expert review and synthesis of the literature. RESULTS: Results from late-stage clinical trials suggest MDMA-assisted therapy for PTSD would be of particular benefit for military populations with PTSD. The unique pro-social properties of MDMA could be leveraged to enhance the therapeutic alliance and patient engagement during neurorehabilitation. CONCLUSION: The unique qualities and benefits of MDMA and MDMA-assisted therapy for PTSD suggest relevant application in military personnel undergoing neurorehabilitation. There are many similarities in patient-therapist dynamics in PTSD treatment and neurorehabilitation. The properties of MDMA which enhance therapeutic alliance, downregulate fear, and increase cognitive flexibility would potentially benefit both military personnel with and without PTSD undergoing neurorehabilitation.
RESUMEN
The Department of Defense (DoD) requires both current and projected estimates of the size of its workforce population with specific categories of disabilities. These estimates support the requirements under the Rehabilitation Act of 1973 as well as the goals outlined in multiple executive orders, including Executive Order 14035, directing DoD to hire employees with disabilities and provide them with reasonable accommodations. These estimates are necessary to determine the assistive technology (AT) required and its anticipated costs through 2031. AT also furthers DoD's goals in aiding the recovery and retention of injured service members, as well as the broader DoD and U.S. Department of Veteran Affairs (VA) community in aiding in the post-service employment of service members who are medically separating. Thus, the authors seek to estimate the potential demand for AT from these groups. The authors give projections of the DoD civilian employee population-and of injured and wounded service members-with specific disabilities categorized by DoD's centralized AT procurer (hearing, vision, cognitive, and dexterity disabilities), as well as the potential anticipated requests for AT by these populations and their costs between 2021 and 2031.
RESUMEN
OBJECTIVES: We investigated whether UK military personnel exposed to sarin during the 'Service Volunteer Programme' at Porton Down had increased rates of mortality or cancer incidence over a 52-year follow-up. METHODS: A historical cohort study assembled from UK military records, comprising male veterans exposed to sarin during the 'Service Volunteer Programme' at Porton Down, UK (n=2975) and a comparison group of similar veterans who did not attend (n=2919). Mortality and cancer incidence data were obtained from national registries up to December 2019. Analysis was conducted using Cox regression adjusted for age, year of birth and service characteristics. RESULTS: Over a median follow-up of 52.2 years (range 2 days to 74.6 years), 1598 (53.7%) sarin-exposed veterans and 1583 (54.3%) non-exposed veterans died. Adjusted HRs for all-cause mortality were raised for any sarin exposure (HR=1.08, 95% CI 1.01 to 1.16), two or more exposures (HR=1.25, 95% CI 1.04 to 1.49) and higher doses (air >15 mg.min/m3) (HR=1.15, 95% CI 1.02 to 1.30). For cause-specific mortality, sarin exposure was associated with deaths from 'other' circulatory diseases (excludes ischaemic and cerebrovascular diseases) (HR=1.41, 95% CI 1.06 to 1.87) and alcohol-attributable deaths (HR=2.66, 95% CI 1.40 to 5.07). There was no association between sarin exposure and overall cancer incidence (HR=1.01, 95% CI 0.93 to 1.10), but cancer incidence was higher for alcohol-related neoplasms (HR=1.24, 95% CI 1.01 to 1.51). CONCLUSIONS: Sarin exposure was associated with increased rates of mortality over a 50-year follow-up. The strongest associations were observed for deaths attributable to alcohol and 'other' circulatory diseases.
RESUMEN
Neutrophilic figurate erythema (NFE) is a rarely reported figurate erythema that clinically presents similarly to erythema annulare centrifugum (EAC) with neutrophil-predominant perivascular and interstitial infiltrate in the dermis on histopathology. We present the case of a 32-year-old active-duty military male who presented with a chronic treatment-resistant skin rash. The rash began on his thighs five years previously and was treated with topical and oral antifungals repeatedly without improvement. The patient was deployed overseas during the rash onset, but the rash persisted upon his return stateside. No triggers were identified. His persistent skin eruption consisted of erythematous polycyclic annular plaques with a "trailing edge" scale. Histologic examination revealed perivascular neutrophils and perivascular and interstitial eosinophils without signs of vasculitis or infection. With only 15 reported cases, it can be difficult to recognize leading to long delays in diagnosis and treatment. Despite having a clinical course similar to EAC, NFE may require anti-neutrophil therapy to resolve completely.
RESUMEN
Introduction: The influence of deployments on family relationships has hardly been investigated. Following a recently proposed new research strategy, military personnel with and without deployment-related life-threatening military incidents during deployment were compared. The hypothesis was that partner and family relationships of military personnel who experienced such an event would deteriorate more. Methods: This study included N = 255 military personnel who had a romantic partner (n = 78 of them had children) when deployed to Afghanistan. Of these, n = 68 military personnel experienced a deployment-related critical event during the deployment, n = 187 did not. Partnership quality was assessed using a semi-structured pre- and post-deployment interview. Results: The partner relationships of military personnel who experienced a deployment-related life-threatening military incident during deployment broke up significantly more often. The partner relationships of all military personnel deteriorated significantly, with greater deterioration after deployment in the group who faced such incidents. These results were independent of age, rank or number of previous deployments. In addition, there was a significant deterioration in the relationships between all military personnel and their children with greater deterioration after deployment in the group who faced such incidents. Conclusion: Life-threatening military incidents during a deployment abroad appear to have a considerable influence on the quality and stability of the partner and family relationships of military personnel. These findings can be used to inform the development of specific pre- and post-deployment measures and training.
