Sickle cell trait (SCT) is a heterozygotic state defined by having one normal hemoglobin gene and one sickle hemoglobin gene. Individuals with SCT are at increased risk for negative health outcomes during intense physical exertion, especially in hot climates and high-elevation locations, or when dehydrated. The U.S. Air Force mitigates this risk through universal screening after accession followed by education of SCT-positive airmen. Airmen who are SCT positive but remain asymptomatic are not restricted in occupation choice or deployment/duty locations based on their SCT status. Previous studies have analyzed the relationship between SCT and health and fitness outcomes. The objective of this study was to analyze the relationship between SCT and career and operational outcomes in a large cohort of airmen and secondarily to analyze the relationship between hemoglobin S (HgbS) percentage and these outcomes. ⋯ SCT-positive and SCT-negative airmen had similar career and operational outcomes, with two exceptions: SCT-positive airmen were less likely to be promoted to staff sergeant within 4 years, and they spent less time at a high-elevation location during their first 6 years of service. The underlying explanation of these findings should be explored with an aim to support SCT-positive airmen and to reduce potentially unwarranted discrepancies. Efforts should continue to reduce the stigma associated with SCT.

At the start of the coronavirus disease 2019 (COVID-19) pandemic, Walter Reed Army Institute of Research (WRAIR) mobilized to rapidly conduct medical research to detect, prevent, and treat the disease in order to minimize the impact of the pandemic on the health and readiness of U.S. Forces. WRAIR's major efforts included the development of the Department of Defense (DoD) COVID-19 vaccine candidate, researching novel drug therapies and monoclonal antibodies, refining and scaling-up diagnostic capabilities, evaluating the impact of viral diversity, assessing the behavioral health of Soldiers, supporting U.S. DoD operational forces overseas, and providing myriad assistance to allied nations. WRAIR personnel have also filled key roles within the whole of government response to the pandemic. WRAIR had to overcome major pandemic-related operational challenges in order to quickly execute a multimillion-dollar portfolio of COVID-19 research. Consequently, the organization learned lessons that could benefit other leaders of medical research organizations preparing for the next pandemic. ⋯ An effective pandemic response requires comprehensive institutional preparedness that facilitates flexibility and surge capacity. The single most important action leaders of medical research organizations can take to prepare for the next pandemic is to develop a quick-reaction force that would activate under prespecified criteria to manage reprioritization of all science and support activities to address pandemic response priorities at the velocity of relevance.

Case Reports
Bidirectional Ventricular Tachycardia in a Young Female: A Case of Andersen-Tawil Syndrome.
Bidirectional ventricular tachycardia (VT) is a rare ventricular dysrhythmia with a limited differential diagnosis that includes digitalis toxicity, catecholaminergic polymorphic VT, aconite poisoning, and genetic channelopathy syndromes, specifically, Andersen-Tawil syndrome (ATS). We present a case of a young female with palpitations found to have bidirectional VT on cardiac event monitor and strong family history of cardiac dysrhythmias. Her physical examination findings included minor dysmorphic features of mandibular hypoplasia, hypertelorism, and clinodactyly. ⋯ Although there are no strong recommendations that exist for treatment of ventricular dysrhythmias associated with this genetic disorder, we demonstrate a case of clinical improvement in a patient with ATS by using the beta-blocker metoprolol succinate. Furthermore, we propose that ATS patients may not need exercise restrictions as overall ventricular ectopy burden decreased with exercise and there was no prolongation of the QT interval. This patient will continue to follow up in our clinic to reassess symptom burden and for continued monitoring for the development of any new features.

Military medical providers are a unique population that encounter different environments across the world. From hospital clinics to war zones, these providers must perform procedures and rely on their training and skill to help their patients. This pilot study aimed to assess the self-confidence of military medical providers performing joint aspiration and injection before and after a simulation workshop in both clinical and austere settings. ⋯ Simulation training can lead to increased medical provider self-confidence in performing musculoskeletal joint aspirations and injections in both clinic and austere settings. The military medicine demographics have had little research in joint injections and provider confidence to date. This pilot study was one of the first to evaluate this unique population. The methods used in this study, and the positive data collected on provider confidence, can be used in larger studies, encompassing other medical providers to increase the confidence of providers throughout various fields of medicine.

Under current regulations, there are three separate authorities for which the Veterans Health Administration (VHA) can pay for emergency medical care received by Veterans in the community. The three VHA authorities have overlapping criteria and eligibility requirements that contribute to a complex and confusing landscape for Veterans when they obtain emergency care in the community. Given the intricacies in how VHA provides coverage for community emergency care and the desire to provide seamless Veteran-centric care, it is imperative to understand Veterans' experiences with navigating coverage for community emergency care. The purpose of this study was to elicit feedback from Veterans about their experiences with and perceptions of community emergency care coverage paid for by VHA. ⋯ Our results highlight the challenges Veterans experience in understanding VHA coverage for community emergency care. Feedback suggests that improving information, support, and communication may help Veterans make timely, informed decisions when experiencing unexpected illness or injury.
