The impact of deployment and combat on mental health of military personnel is well described. Less evidence is available to demonstrate and summarize the incidence, prevalence, and risks of these exposures on physical health. This study aims to (1) systematically review the available literature to determine the incidence and prevalence of physical health conditions among military personnel during and after deployment and (2) investigate the risks of deployment and combat exposure on physical health. ⋯ Given the characteristics of included studies and extracted data, the magnitude of the found differences in incidence and prevalence rates is most likely to be due to methodological heterogeneity. The specific exposures (e.g., infrastructure, environmental conditions, and activities during deployment) are suggested to be the determinants of (post) deployment physical health problems and need to be addressed to decrease the impact of deployment. Findings from this systematic review highlight which conditions should be addressed in response to service members' health and wellness needs in the (post)deployment phase and may be used by clinicians, researchers, and policy-makers. However, knowledge gaps regarding the potential risk factors during deployment and combat still exist. Studies using consistent methods to define and measure the physical health conditions and specific exposures are needed.

A military exists in a unique position. It is an organization in which active duty members knowingly join or are conscripted into service with the understanding that there is an increased risk of mental and/or bodily harm as compared to many other occupations. However, while the nature of the profession can inherently be dangerous, it does not follow that its members be placed at undue excess risk if that risk can be reasonably avoided or reduced. ⋯ The ethical obligation is fortified by the extent of control a military exercises over its personnel. Taken together, these factors necessitate a concerted effort by militaries to remain cognizant of the ethical impacts of their policies and practices and to ensure focus remains on the well-being and readiness of its personnel. As such, militaries have ethical responsibilities to promote healthy social determinants of health among their service members via policies and public health measures.

The glia-operated glymphatic system, analogous to but separate from the lymphatics in the periphery, is unique to brain and retina, where it is very closely aligned with the arteriolar system. This intimate relationship leads to a "blood vessel like" distribution pattern of glymphatic vessels in the brain. The spatial relationship of glymphatics, including their essential component aquaporin-4 with vascular pericytes of brain arterioles is critical to functionality and is termed "polarization". ⋯ Damage to the glymphatic system might explain the brain edema so often seen following TBI or other insult. Moreover, similar damage should be expected in response to seizures, which can often be associated with chemical exposures as well as with TBI. Military operations, whether night operations or continuous operations, quite often impose limitations on sleep. As glymphatic function is sleep-dependent, sleep deprivation alone could compromise glymphatic function, as well, and might in addition, explain some of the well-known performance deficits associated with sleep deprivation. Possible effects of submarine and diving operations, chemical agents (including seizures), as well as high altitude exposure and other threats should be considered. In addition to the brain, the retina is also served and protected by the glymphatic system. Accordingly, the effect of military-related risks (e.g., exposure to laser or other threats) to retinal glymphatic function should also be considered. An intact glymphatic system is absolutely essential to support normal central nervous system functionality, including cognition. This effects a broad range of military threats on brain and retinal glymphatics should be explored. Possible preventive and therapeutic measures should be proposed and evaluated, as well.

Traumatic injuries were the most common reason for admission of pediatric patients to military hospitals during the recent wars in Iraq and Afghanistan. We compare survival and interventions between female and male pediatric casualties. ⋯ Among pediatric patients treated by U.S. medical personnel in Iraq and Afghanistan, females had a lower survival to hospital discharge despite similar severity of injury. Further studies are necessary to elucidate causes for this finding.

Residency programs in the combined specialty of Internal Medicine-Pediatrics (Med-Peds) are not offered in the military graduate medical education system despite existing in the civilian sector for over 50 years. This residency consists of 4 years of training and results in the development of board-certified internists and pediatricians who can care for patients from infancy to death. This versatility, combined with an emphasis on the transition from childhood to adulthood, would be valuable to the Military Health System. ⋯ As there are already military residency programs in pediatrics and internal medicine, the required infrastructure for such a training program exists. The addition of this residency may also lead to more interest in military medicine from prospective applicants to medical school. This essay uses personal experience to explain how the addition of this specialty to the military would benefit the medical mission domestically and abroad.
