The worldwide COVID-19 pandemic poses challenges to healthcare capacity and infrastructure. The authors discuss the structure and efficacy of the U.S. Navy's response to COVID-19 and evaluate the utility of this endeavor, with the objective of providing future recommendations for managing worldwide healthcare and medical operational demands from the perspective of Navy Neurosurgery. ⋯ The U.S. Navy neurosurgical response to the COVID-19 pandemic was swift and altruistic. Although neurosurgical pathologies were limited among the presenting patients, readiness and manpower continue to be strong influences within the Armed Forces. The COVID-19 response demonstrates that neurosurgical assets can be rapidly mobilized and deployed in support of wartime, domestic, and global humanitarian crises to augment both trauma and critical care capabilities.

Review Case Reports
Fatal Isoniazid Hepatotoxicity in the Deployed Environment.
Deployed clinicians have limited resources at their disposal to augment medical decision-making and management. All deploying personnel undergo predeployment medical assessment to evaluate their fitness for deployment. The purpose of predeployment screening is to allow for anticipation of medical needs that may arise which could challenge the available medical resources in an expeditionary environment. ⋯ Isoniazid is not specifically mentioned as a disqualifying medication, though it is well known to have the potential of causing drug-induced liver injury. Here, a case of fatal isoniazid-induced drug-induced liver injury in a deployed setting is presented with a review of current latent tuberculosis infection literature. Our goal is for the reader to form their own opinion whether or not isoniazid should be used in the forward environment.

The goal of Pressurized Submarine Escape Training (PSET) is to prepare future submariners for the physical and mental challenges of escaping a disabled submarine and promote proper handling of the Beaufort Ltd Mk 11 Submarine Escape and Immersion Equipment suit. Training participants are only permitted to enter PSET after strict health screening protocols have been met to optimize trainees' safety. Before PSET, trainees are given detailed, one-on-one instruction on proper ascent mechanics by specially trained Navy Dive instructors. ⋯ Prompted by the recent incidents relative to the low reported incidence rate of AGE in historical PSET training, reported potential risk factors were compared with better understand potential etiologies of AGE in already medically screened individuals. Risks and benefits of PSET were listed, compared, and analyzed. The relative safety and cost effectiveness of this rigorous form of training was reconfirmed.

The U.S. forward military surgical assets have deployed throughout the Iraq and Afghanistan theaters of operations to maintain surgical support for injured service members in compliance with the "golden hour" as specified in the Gates Memorandum. The support of evacuation times of less than 60 minutes to a surgical capability has resulted in smaller surgical teams being deployed to an increased number of locations. Over the last 5 years, the combat trauma patient encounters have decreased. Although some Role 2 medical treatment facilities (MTFs) maintain a medical mission, most of them are set up to provide trauma care. The largest and busiest Role 2 MTF is located near Kabul and serves the NATO population. The aims of this review are to examine the epidemiological data of the largest Role 2 MTF in theater, to examine damage control surgical capability optimization in a facility with a largely medical mission, and to analyze what this may mean in the context of surgical skill atrophy. ⋯ The ratio of operative cases per surgeon is substantially higher at these Role 3 facilities, when compared to Role 2 facilities, although still significantly lower than would be expected at an U.S. Level 1 trauma center. This is consistent with other larger epidemiological studies on forward MTF workload. The vast majority of patient care is related to treatment of disease and preventative medicine. Only 0.7% of the large volume of patient visits evaluated were for battle injuries. There is a scarcity of both surgical and trauma patients, with a more pronounced reduction at Role 2 compared to Role 3 facilities. This is especially evident here with a facility that has such a large patient population but low trauma or surgical patient volume. Sustaining trauma and surgical skills for both surgeons and trauma teams with a paucity of trauma patients is a significant concern.

Randomized Controlled Trial
Influence of Self-managed Rehabilitation on Work Efficiency in Active Duty Military With a Knee Injury.
Knee injuries associated with intense physical training are one of the most frequent injuries associated with medical encounters for military members. The purpose of this study was to evaluate four approaches to physiotherapy rehabilitation and their effects on work efficiency in active duty military with a knee injury. The four groups included neuromuscular electrical stimulation (NMES), walking with a weighted vest (WALK), combined NMES/Walk, and standard physiotherapy rehabilitation. All groups received standard physiotherapy rehabilitation.We have previously reported that quadriceps muscle strength improved over 18 weeks in the study for the three interventions relative to standard rehabilitation alone. This report presents results from an examination of work efficiency as evaluated during a step test while measuring oxygen utilization. ⋯ All groups showed improved submaximal exercise efficiency based on oxygen utilization, with the intervention groups showing a greater improvement in work efficiency as compared to standard rehabilitation. Knee injuries can be problematic for active duty members because of reduced mobility leading to deconditioning and associated declines in work efficiency. Rehabilitative programs, including those described in this study, may minimize loss of work efficiency and fitness and promote a quicker recovery.
