Spain is the country with the highest number of health care workers affected by coronavirus disease 2019 (COVID-19) in the world. The aim of this study was to describe the epidemiology of severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) infection in health care worker (HCW) at the Gómez Ulla Military Hospital (HCDGU). ⋯ One hundred fifty professionals answered the questionnaire. Cases were defined as those who tested positive in the diagnostic tests (n = 28, 20.7%) and no cases were those who tested negative (n = 107, 79.3%). Therefore, the percentage of SARS-CoV-2 in the GUMH was 20.7%. Of the total number of cases, 64.3% were men (P < .05), with a mean age of 47.1 years (SD 13.3), a mean BMI of 25.3 (SD 3.8), and 48.2% being overweight. Of the total cases, 59.3% had "A" blood group type and 69.2% were Rh positive. 50% were physicians, 32.1% were nurses, and 17.9% were auxiliary nurses (P < .05). Cases and controls with vitamin D deficiency and who took supplements had a lower risk of suffering COVID-19, with significant differences. Fever, cough, and diarrhea were found in at least 50% of the samples with significant differences.

Segmental bone defects (SBDs) are devastating injuries sustained by warfighters and are difficult to heal. Preclinical models that accurately simulate human conditions are necessary to investigate therapies to treat SBDs. We have developed two novel porcine SBD models that take advantage of similarities in bone healing and immunologic response to injury between pigs and humans. The purpose of this study was to investigate the efficacy of Bone Morphogenetic Protein-2 (BMP-2) to heal a critical sized defect (CSD) in two novel porcine SBD models. ⋯ We have developed two porcine CSD models, including fixation with IMN and with dual-plate fixation. Porcine models are particularly relevant for SBD research as the porcine immunologic response to injury closely mimics the human response. BMP-2 restored healing in both CSD models, and the effects were evident within the first month after injury. These findings support the use of both porcine CSD models to investigate new therapies to heal SBDs.

The anesthesiology in-training exam (ITE) is a 200-item multiple-choice assessment completed annually by physician residents. Because all matriculated U.S. Department of Defense (DoD) anesthesiology residents are "hired" by the DoD after residency graduation, it is important to ensure that ITE performance, as a proxy for core competencies achievement, is maximized. ⋯ Resident physicians enter residency with varying degrees of past academic success, and it is important to develop early strategies to support them in acquiring the requisite knowledge base.

Hepatitis C Virus (HCV) infection is a leading cause of chronic liver disease and hepatocellular carcinoma, and universal screening of all adults is recommended. Treatment with new direct antiviral agents are well tolerated and highly effective and decrease morbidity and mortality from HCV. The timely treatment of active-duty Service members (SMs) is essential to prevent complications of HCV and to ensure medical readiness and safety of the Department of Defense blood supply. We performed a retrospective review of the quality of care of Navy Active Duty (AD) and reserve SMs diagnosed with HCV to assess rates of successful treatment and compliance with national guideline recommendations and identify potential challenges to receiving curative HCV therapy. ⋯ As HCV screening recommendations expand to include all adults, more HCV infections will be identified in both the active and reserve components. Modern HCV therapies are both relatively short in duration as well as curative, allowing for the restoration of medical readiness and military service retention. Despite these advantages, we identified challenges of effecting HCV cures in a mobile military population. We recommend centralized compliance monitoring of not only HCV force screening but also HCV treatment to ensure maximized military medical readiness.

To understand the prevalence of comorbidities associated with traumatic brain injury (TBI) patients among active and reserve service members in the U.S. Military. ⋯ A large proportion of our TBI patients are afflicted with comorbidities, particularly post-TBI, indicating many have a complex profile. The military health system should continue tracking comorbidities associated with TBI within the U.S. Military and devise clinical practices that acknowledge the complexity of the TBI patient.
