Pressurized Submarine Escape Training (PSET) physically prepares submariners to safely escape a submarine at depth. Failure to complete PSET is not a submarine service disqualification. Serious medical incidents are rare, but the safety record tradeoff has been low throughput. ⋯ Basic Enlisted Submarine School students were more likely to be disqualified and attrite than other submariner groups, and black/African American (ORadj 1.53) students were more likely to attrite than white students. Only cold/congestion/cough (ORadj 1.52), trouble swimming (ORadj 1.53), and screening during cold/flu season (ORadj 1.28), were associated with training attrition. Recommendations to modify screening requirements are listed in conclusions.

Operative case volumes for military surgeons are reported to be significantly lower than civilian counterparts. Among the concern that this raises is an inability of military surgeons to achieve mastery of their craft. ⋯ Obtaining mastery of general surgery is a nearly impossible proposition given the current care models at Army MTFs. Alternative staffing and patient care models should be developed if Army surgeons are to be masters at their craft.

The prevalence of smokeless tobacco use among U.S. active duty service members has been much higher than in the U.S. general population. The association between deployment and smokeless tobacco use has not been well studied. We investigated the association between deployment and smokeless tobacco use among U.S. active duty service members. We also evaluated the modification effects from other factors related to smokeless tobacco use on the deployment-smokeless tobacco use association. ⋯ Military deployment was associated with smokeless tobacco use among active service members. However, the influence of military deployment on smokeless tobacco use was not equally strong on all service members. Subjects who never smoked cigarettes, who had no family history of use and who had low perception of harm were the most susceptible subgroups to deployment-related smokeless tobacco use. This study has implications to identify high-risk subgroups to reduce smokeless tobacco use in the U.S. military.

A new product prototype system for diagnosing vision and neurological disorders, called NeuroDotVR, is described herein: this system utilizes a novel wireless NeuroDot brain sensor [Versek C et al. J Neural Eng. 2018 Aug; 15(4):046027] that quantitatively measures visual evoked potentials and fields resulting from custom visual stimuli displayed on a smartphone housed in a virtual reality headset. ⋯ Steady state and transient visual evoked potentials and fields using reversing checkerboard stimuli are presented with case studies in amblyopia, glaucoma, and dark adaptation. These preliminary data sets highlight potential clinical applications that may be pursued in further product development and scientific studies.

Orthopedic trauma is a significant military problem, causing several of the most disabling conditions with high rates of separation from duty and erosion of military readiness. The objective of this report is to summarize the findings of case series of a non-opioid therapy-percutaneous peripheral nerve stimulation (PNS) - and describe its potential for postoperative analgesia, early opioid cessation, and improved function following orthopedic trauma. ⋯ Collectively, the results of these three clinical studies demonstrated that percutaneous PNS can provide substantial pain relief, reduce opioid use, and improve function. These outcomes suggest that there is substantial potential for the use of percutaneous PNS following orthopedic trauma.
