Neuroendocrine tumors (NET) are rare malignancies that contain neural and endocrine cells with a median age of diagnosis of 63 years. NETs are typically located in the gastrointestinal (GI) tract, the pancreas, or the lungs. Within the GI tract, the most common locations for NETs are the small bowel, appendix, or rectum. ⋯ NETs arising from the left side of the colon are very uncommon. While most NETs are well-differentiated by histology and are slow growing, 7% are poorly differentiated and usually progress rapidly. While rare, it is vital to be vigilant for this reason We present such a case of poorly differentiated metastatic NET of the sigmoid colon in a young active duty service member.

Obesity is a significant health concern for veterans and individuals with spinal cord injury, yet screening for overweight/obesity can be challenging. This study examines how healthcare providers screen for overweight/obesity and the challenges encountered in identifying overweight/obesity in veterans and persons with spinal cord injury. ⋯ This study identified the most commonly used indicators of weight or body composition in veterans and persons with spinal cord injury and highlighted providers' concerns with these measures. Future research is needed to identify the most feasible, accurate, and appropriate health indicators that could be used in a clinical setting to identify overweight and obesity in this population.

Immediate evacuation of burn casualties can be challenging in austere environments, and it is predicted to be even more difficult in future multi-domain battlespaces against near-peer foes. Therefore, a need exists to treat burn wounds at the point of injury to protect the exposed injury for an extended period. In this study, we compare two commercially available FDA-approved therapies to the current gold standard of care (GSOC), excisional debridement followed by the application of split-thickness skin graft, and the standard for prolonged field care, silver sulfadiazine (SSD) cream. The shelf-stable therapies evaluated were irradiated human skin (IHS) allograft and polylactic acid (PLA). Our objective was to study whether they have the potential capability to reduce the need for evacuation to a burn center for surgical intervention so that the combat power can be preserved in the field. ⋯ This preclinical study demonstrated that the use of the PLA and the IHS dressings resulted in similar outcomes to the GSOC-treated burns in several key metrics of wound healing. These therapies represent a potentially useful tool in current and future battlespaces, where surgical intervention is not possible. The products are lightweight and, more importantly, stable at room temperature for their entire shelf lives. This would allow for easy storage and transport by medical practitioners in the field.

Patient demographics, such as sex and age, are known risk factors for undergoing revision following primary total hip arthroplasty (THA). The military population is unique because of the increased rates of primary and secondary osteoarthritis of the hip. Treatment options are limited for returning patients to their line of duty; however, THA has been shown to be an effective option. The primary purpose of this study was to evaluate and contrast the demographic differences of patients undergoing primary THA between the U.S. active duty military population and the general population. The secondary goal was to identify the proportion of primary THA performed at the MTF within the military health system (MHS). ⋯ Patients in the MHS are undergoing THA at a younger age and are more likely to be male compared to the general population. A significant portion of primary THAs in the MHS are also being performed at civilian institutions. These demographics may result in increased risk of revision; however, long-term studies are warranted to evaluate survivorship in this unique population.

Coronavirus disease 2019 (COVID-19) and the resulting societal reaction presented new challenges to the medical community by limiting patient access to care in 2020 and 2021. The Navy Postgraduate Dental School (NPDS) oral and maxillofacial pathology biopsy service is dependent on in-office physician or dentist appointments and patient biopsies. The purpose of this study was to understand the regulatory and societal impacts of COVID-19 restrictions on biopsy service submissions by assessing NPDS biopsy submission quantities and disease distribution. ⋯ Overall, preventative COVID-19 health measures and protocols resulted in a reduction in biopsy submission frequency, particularly during the second quarter (April to June) of 2020. However, case counts for malignant biopsies remained consistent between pre-COVID and COVID time intervals, suggesting that the identification and analysis of cases requiring follow-on care were unaffected by COVID-19 protocols.
