Impact of SARS-CoV-2 Arrival Surveillance Screening by Nucleic Acid Amplification Versus Rapid Antigen Detection on Subsequent COVID-19 Infections in Military Trainees.

BACKGROUND: For persons entering congregate settings, optimal severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) arrival surveillance screening method, nucleic acid amplification test (NAAT) versus rapid antigen detection test (RADT), is debated. To aid this, we sought to determine the risk of secondary symptomatic coronavirus disease 19 (COVID-19) among military trainees with negative arrival NAAT or RADT screening. METHODS: Individuals who arrived for US Air Force basic military training from 1 January-31 August 2021 were placed into training groups and screened for SARS-CoV-2 via NAAT or RADT. Secondary symptomatic COVID-19 cases within 2 weeks of training were then measured. A case cluster was defined as ≥5 individual symptomatic COVID-19 cases. RESULTS: 406 (1.6%) of 24 601 trainees screened positive upon arrival. The rate of positive screen was greater for those tested with NAAT versus RADT (2.5% vs 0.4%; RR: 5.4; 95% CI: 4.0-7.3; P < .001). The proportion of training groups with ≥1 positive individual screen was greater in groups screened via NAAT (57.5% vs 10.8%; RR: 5.31; 95% CI: 3.65-7.72; P < .001). However, NAAT versus RADT screening was not associated with a difference in number of training groups to develop a secondary symptomatic case (20.3% vs 22.5%; RR: .9; 95% CI: .66-1.23; P = .53) or case cluster of COVID-19 (4% vs 6.6%; RR: .61; 95% CI: .3-1.22; P = .16). CONCLUSIONS: NAAT versus RADT arrival surveillance screening method impacted individual transmission of COVID-19 but had no effect on number of training groups developing a secondary symptomatic case or case cluster. This study provides consideration for RADT arrival screening in congregate settings.

Clinical Practice Guidelines for Exertional Rhabdomyolysis: A Military Medicine Perspective.

ABSTRACT: Exertional rhabdomyolysis (ER) is an uncommon condition with a paucity of evidence-based guidance for diagnosis, management, and return to duty or play. Recently, a clinical practice guideline for diagnosis and management of ER in warfighters was updated by a team of military and civilian physicians and researchers using current scientific literature and decades of experience within the military population. The revision concentrated on challenging and controversial clinical questions with applicability to providers in the military and those in the greater sports medicine community. Specific topics addressed: 1) diagnostic criteria for ER; 2) clinical decision making for outpatient versus inpatient treatment; 3) optimal strategies for inpatient management; 4) discharge criteria; 5) identification and assessment of warfighters/athletes at risk for recurrent ER; 6) an appropriate rehabilitative plan; and finally, 7) key clinical questions warranting future research.

Case Report and Management of Discovery of Lower Extremity Venous Thrombosis on Musculoskeletal Ultrasound.

Despite the increasing availability of ultrasound in the ambulatory setting, there has yet to be an established consensus on what constitutes proper diagnosis of a deep vein thrombosis (DVT) using point-of-care ultrasound (POCUS) as well as proper management if one is suspected using this modality. This case report presents the discovery of non-compressible veins during a musculoskeletal (MSK) POCUS examination for a calf injury and explores the current standard of care for the appropriate subsequent steps in the diagnosis and management of suspected lower-extremity (LE) DVT using MSK POCUS.

Deaths Among U.S. Air Force Basic Military Trainees, 2008-2020.

INTRODUCTION: The U.S. Air Force (USAF) Basic Military Training (BMT), a rigorous training program for all enlisted members of the USAF, trains roughly 36,000 recruits annually. Transforming civilians into ready warrior airmen has inherent risks to trainee health, which has infrequently included death. While the average death rate at USAF BMT has decreased between 1956 and 2007 due to process improvement and preventive medicine efforts, further review is warranted to examine the deaths that have occurred since the last published period (1997-2007) and to determine the impact policy changes and updates have had on death rates since that time. Therefore, the purpose of this paper is to identify death rates and types from 2008 to 2020, explore policy implementation, and identify areas needing further improvement or modifications to the overall safety, fitness, and health of USAF BMT trainees. MATERIALS AND METHODS: All deaths were examined and reviewed from 2008 through 2020 for trainees attending the USAF BMT using medical records and autopsy reports. Death rates were calculated using the total population of trainees in a given year as well as over the entire 13-year study period. RESULTS: From 2008 to 2020, five deaths occurred among USAF BMT trainees (one cardiac, two exertional sickling due to sickle cell trait, one infection, and one suicide). This resulted in an overall average death rate of 1.08 per 100,000 trainees, as compared to 1.46 per 100,000 from 1997 to 2007. The last death in the study period occurred in 2016. CONCLUSION: A modest downward trend of average death rate has continued since 2007, and no deaths from 2016 through 2020 represents the longest time frame without any deaths at USAF BMT over all times reported (dating back to 1956) which suggest that emergency best practice policies are/have improved. However, cardiac death rate and suicide rate have not changed since the last report. Policies and practices should be continuously reviewed and refined to reduce the risk of death at USAF BMT.

Running Gait Training Improves Outcomes at United States Air Force Basic Military Training.

INTRODUCTION: The aim is to investigate the impact of large-group, motor learning-based running gait training on injury risk in United States Air Force (USAF) Basic Military Training (BMT). DESIGN: A prospective quasi-experimental program evaluation is used. MATERIALS AND METHODS: Medical providers taught running gait form to groups of trainees in the first week of training of BMT from August 2020 to March 2021. The main outcome measures included risk ratio of reported injuries, removal from training because of injury, and separation from service because of injury. RESULTS: Of BMT trainees, 2,205 underwent group, motor learning-based running gait training; this was compared with two intake groups (nA = 3,941 and nB = 2,041) who were only given introductions to sports medicine staff in a classroom setting. Reported pain complaints increased (χ2 = 27.4A and 20.83B, P < .001). Risk ratios for more severe injuries necessitating time out of training or separation from USAF were reduced, although these were statistically not significant (13%, P = .48 and 22%, P = .29, respectively). Leadership implemented gait training across BMT, and data from the following 8 weeks of intake (n = 6,223) demonstrated similar trends in increases in patient reports of pain (χ2 = 67.25, P < .001) but significantly reduced risk ratios of removal from training (32%, χ2 = 16.35, P < .001) or separation (32%, χ2 = 12.54, P < .001). CONCLUSIONS: While not previously shown to mitigate injury, large-group, running gait training was associated with a significant reduction in injury severity defined by training delays and separation from service in USAF BMT.

Osteopathic Manipulative Treatment as a Novel Way to Manage Postvasectomy Pain Syndrome.

Postvasectomy pain syndrome (PVPS) can be debilitating and is notoriously difficult to treat, often requiring a multidisciplinary approach. In this case report, osteopathic manipulative treatment (OMT) was used to treat a patient with PVPS. After vasectomy, an otherwise-healthy man experienced chronic right testicular pain, aggravated by exercise, touch, and sexual intercourse, resulting in marital strain and an inability to perform routine fitness activities. Symptoms persisted for 8 years, despite lifestyle modifications, orally administered pain regimens, pelvic floor physical therapy, nerve blocks, steroid injections, epididymectomy, spermatic cord denervation, and counseling. After the patient's urologist suggested orchiectomy, his family medicine physician referred him for OMT. The OMT interventions, applied over a 4-month period, were directed at the lumbar spine, pelvis, pelvic floor, and lower abdomen. After treatment, the patient reported absence of testicular pain most of the time and described his quality of life as "10 times better." Literature review revealed no reports of OMT used to manage PVPS.

Third-Party Evaluation: A Review of Dietary Supplements Dispensed by Military Treatment Facilities From 2007 to 2011.

INTRODUCTION: Third-party certification/verification of dietary supplements (DS), although not mainstream, is one way to help ensure high-quality products. In the medical setting, physicians may prescribe DS to correct a deficiency or improve a health care outcome, and they want products of a certain standard of quality, free of adulteration/contamination. OBJECTIVE: We reviewed DS dispensed from all Department of Defense military treatment facilities over a 5-year period to determine which products had been third-party reviewed and certified/verified. METHODS: By using product name, manufacturer, and/or National Drug Codes, we examined product listings on the websites of three independent-evaluating organizations. RESULTS: Over 1.5 million dietary supplement prescriptions consisting of 753 different products were dispensed from 2007 through 2011. Less than 3.6% of the products examined were third-party certified/verified by any of the three most well-known evaluation organizations: 19 were verified by United States Pharmacopeial Convention; 9 products were reviewed and 8 certified by ConsumerLab; and none of the products were certified by NSF International. CONCLUSION: Most DS dispensed by military treatment facilities are not reviewed by a third party. This is not unexpected, as third party certification is not yet mainstream. However, one way to reduce potential hazards and exposure to unsafe products is to encourage use of supplements that have third-party certification/verification.
