Occupational exposure to repetitive, low-level blasts in military training and combat has been tied to subconcussive injury and poor health outcomes for service members. Most low-level blast studies to date have focused on explosive breaching and firing heavy weapon systems; however, there is limited research on the repetitive blast exposure and physiological effects that mortarmen experience when firing mortar weapon systems. Motivated by anecdotal symptoms of mortarmen, the purpose of this paper is to characterize this exposure and its resulting neurocognitive effects in order to provide preliminary findings and actionable recommendations to safeguard the health of mortarmen. ⋯ Mortarmen experienced high cumulative blast exposure coinciding with altered neurocognition that is suggestive of blast-related subconcussive injury. These neurocognitive effects occurred even in mortarmen with average BOP below the 4 psi safety threshold. While this study was limited by a small sample size, its results demonstrate a concerning health risk for mortarmen that requires additional study and immediate action. Behavioral changes like ducking and standing farther from the mortar when firing can generally help reduce mortarmen BOP exposure, but we recommend the establishment of daily cumulative safety thresholds and daily firing limits in training to reduce cumulative blast exposure, and ultimately, improve mortarmen's quality of life and longevity in service.

This case discusses a 34-year-old active duty male who presented to the emergency department with a 2-week persistent headache. His initial review of symptoms was reassuring until a detailed neurologic examination on his second visit revealed a visual deficit in the left upper quadrant. ⋯ The patient was admitted for medical management and subsequently found to have suffered a small infarction of right lingual gyrus cortex on magnetic resonance imaging. This case illustrates the importance of maintaining a broad differential diagnosis and high index of suspicion in the patient with new focal neurologic findings in order to diagnose a potentially fatal disease.

Medical direction has been the cornerstone to safe and effective prehospital and enroute care since the establishment of emergency medical services (EMS). Medical oversight by a physician has been shown to improve clinical outcomes in both settings. When the Navy Regional Office of the EMS Medical Director was established in 2016, it brought additional resources, including the addition of a paramedic and nurse EMS analyst and recruitment of additional local medical directors (LMDs). This, combined with the engagement of military leadership, allowed for expansion and improvement of medical direction in our prehospital and enroute care system and the establishment of a continuous quality improvement (CQI) program. ⋯ Our results demonstrate that improvement in medical oversight in a large regional prehospital system can be achieved through persistence and engagement of nonmedical leadership.

Traumatic brain injury (TBI) entails chronic neurological symptoms and deficits, such as smell and taste impairment. In the general population, a prevalence of 13.5% for smell impairment, 17% for taste impairment, and 2.2% for both have been reported. Studies establishing prevalence of sensorial dysfunction in the U.S. general population showed that prevalence increased with age and was higher in ethnic minorities and men. To understand the mechanisms that lead to these deficits, the prevalence of sensory dysfunction was studied in the Veteran TBI population of the VA Caribbean Healthcare System (VACHS). The aims were to find the prevalence of sensorial dysfunction in smell and/or taste in TBI patients at the VACHS Polytrauma Clinic and its association with demographic characteristics and medical comorbidities. The hypothesis was that the prevalence of sensory dysfunction in smell and/or taste of VACHS Veterans (mostly Hispanics minority) with TBI will be higher than the one historically reported in the literature for the U.S. general population. ⋯ The investigators found that the prevalence of sensory dysfunction in smell and/or taste in VACHS Veterans with TBI was 38.3% (n = 31). A significant association was found between smell and/or taste dysfunction and being a combat veteran (P = .018). A marginally significant association to obesity was also observed (P = .053). To the scientific community, the results will serve as a base for sensorial dysfunction and TBI research given that this prevalence, and the correlation to demographics and comorbidities, has not been fully established in the Veteran population.

Brachytherapy, with external beam radiation, increases survival in the treatment of locally advanced cervical cancer (LACC). In 2016, Robin et al. reported only 44% of patients received standard-of-care (SOC) brachytherapy in the USA. The Pacific Island Health Care Project has provided humanitarian medical care to women from the U.S. Associated Pacific Islands (USAPI) for three decades at Tripler Army Medical Center (TAMC), a military health care system (MHS) facility. We evaluated whether this underserved and understudied patient population received SOC treatment for LACC at TAMC. ⋯ Women with cervical cancer from USAPI in the PIHCP program treated at TAMC received significantly higher rates of SOC radiation treatment than the U.S. population on average. This highlights the ability of PIHCP, through the MHS, to deliver SOC treatment for cervical cancer to an otherwise underserved patient population.
