BACKGROUND AND OBJECTIVES: Understanding the real-world impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) mitigation measures, particularly vaccination, in children and adolescents in congregate settings remains important. We evaluated protection against SARS-CoV-2 infection using school-based testing data. METHODS: Using data from Utah middle- and high-school students participating in school-wide antigen testing in January 2022 during omicron (BA...

Purpose: To report an incident of a breakthrough deep vein thrombosis (DVT) and potential example of a drug-drug interaction in a patient treated with edoxaban and rifabutin who was being treated for respiratory tuberculosis. Case: A 76-year-old male presented with anemia requiring transfusion and subsequent shortness of breath that was later diagnosed to be respiratory tuberculosis. He experienced a prolonged hospital stay due to persistently positive Mycobacterium tuberculosis respiratory samples and a complicated social situation that required continuous hospitalization for approximately five months...

OBJECTIVE: The study investigated the association over time between the rates of anger/hostility and suicidality in post-9/11 veterans as a function of time following separation from the military and combat exposure. METHOD: Structured clinical interviews were conducted with N = 2,580 Iraq/Afghanistan-era U.S. military veterans serving since 9/11/01. For each participant, a postseparation interval was calculated as the time between military separation and the clinical interview, with a range of up to 9 years...

While a number of enteric coatings and pH-sensitive oral delivery vehicles have been developed, they lack the ability to sufficiently protect proteins from proteolytic degradation once released from the carrier. In this work, we show that H-bonded, pH-sensitive poly(methacrylic acid-grafted ethylene glycol) glycol (henceforth designated as P(MAA-g-EG) gels) exhibit great promise as protein carriers, as they utilize poly(ethylene glycol) (PEG) chains to promote mucoadhesion in the small intestine, increasing the chances that the drug is released within the villus of the absorptive intestinal wall...

Infection, autoimmunity, and cancer are the principal human health challenges of the 21st century and major contributors to human death and disease. Often regarded as distinct ends of the immunological spectrum, recent studies have hinted there may be more overlap between these diseases than appears. For example, pathogenic inflammation has been demonstrated as conserved between infection and autoimmune settings. T resident memory (T RM ) cells have been highlighted as beneficial for infection and cancer. However, these findings are limited by patient number and disease scope; exact immunological factors shared across disease remain elusive...

RATIONALE: Acute lung injury (ALI) carries a high risk of mortality but has no established pharmacologic therapy. We previously found that experimental ALI occurs through natural killer (NK) cell NKG2D receptor activation and that the cognate human ligand, MICB, was associated with ALI after transplantation. OBJECTIVE: To investigate the association of a common missense variant MICBG406A with ALI. METHODS: We assessed MICBG406A genotypes within two multicenter observational at risk for ALI: primary graft dysfunction (PGD, N = 619) and acute respiratory distress syndrome (ARDS, N = 1,376)...

INTRODUCTION: Mild traumatic brain injury (mTBI) caused by repetitive low-intensity blast overpressure (relBOP) in military personnel exposed to breaching and heavy weapons is often unrecognized and is understudied. Exposure to relBOP poses the risk of developing abnormal behavioral and psychological changes such as altered cognitive function, anxiety, and depression, all of which can severely compromise the quality of the life of the affected individual. Due to the structural and anatomical heterogeneity of the brain, understanding the potentially varied effects of relBOP in different regions of the brain could lend insights into the risks from exposures...

OBJECTIVE: Imaging changes after stereotactic radiosurgery (SRS) can occur for years after treatment, though the available data on the incidence of tumor progression and adverse radiation effects (ARE) are generally limited to the first two years after treatment. METHODS: A single institution retrospective review was conducted for patients who had greater than 18 months of imaging follow-up. Patients who had one or more metastatic brain lesions treated with Gamma Knife SRS were assessed for time to radiographic progression; those who progressed 18 months or longer out from the time of initial treatment were included in the study...

PURPOSE: Fournier's gangrene (FG), a rapidly progressive necrotizing soft tissue infection of the external genitalia and perineum, necessitates urgent surgical debridement. The time to surgery effect of preoperative computed tomography (CT) in managing this condition is yet to be fully explored. The purpose of this study was to assess whether obtaining a preoperative CT in patients with FG impacts the time to surgical intervention. METHODS: This was a single-center retrospective study of patients who underwent CT prior to surgical debridement of FG during a 9-year period vs patients who did not undergo CT...

BACKGROUND: Sentinel node biopsy is performed to stage clinically and radiographically occult regional disease in cases of malignancy, including cutaneous cancer such as melanoma. The use of tumescent anesthesia with sentinel node biopsy for cutaneous malignancies has not been well studied. Therefore, we aimed to compare the rate of successful sentinel node identification and estimated blood loss between patients who underwent sentinel node biopsy with and without the use of tumescent anesthesia...

Primary graft dysfunction (PGD) limits clinical benefit after lung transplantation, a life-prolonging therapy for patients with end-stage disease. PGD is the clinical syndrome resulting from pulmonary ischemia-reperfusion injury (IRI), driven by innate immune inflammation. We recently demonstrated a key role for NK cells in the airways of mouse models and human tissue samples of IRI. Here we used 2 mouse models paired with human lung transplant samples to investigate the mechanisms whereby NK cells migrate to the airways to mediate lung injury...

PURPOSE/OBJECTIVE(S): The role of radiotherapy (RT) for diffuse large B-cell lymphoma (DLBCL) is unclear. In patients treated with upfront chemotherapy for DLBCL, indications for RT are often considered to be bulky (7.5 cm +) or extranodal disease. This is thought to improve outcomes through improvement in local control. Many trials call into question the actual benefit of RT. Alliance/CALGB 50303 was a randomized phase III trial comparing two chemotherapy regimens for the treatment for DLBCL in which no patients were to receive RT...

PURPOSE/OBJECTIVE(S): Extrapulmonary small cell carcinoma (EPSCC) is a rare entity with 1,000 cases reported annually in the U.S. It can originate in a variety of sites outside of the lung, and even with locoregional disease, relapse is common, and survival is poor. Prophylactic cranial irradiation (PCI) can improve survival in small cell lung carcinoma, however in the setting of EPSCC its role has not been clearly defined. We offer a single institution retrospective review of EPSCC, outlining the incidence of brain metastases, treatment paradigms, and patient outcomes...

BACKGROUND: Peri-diagnostic vaccination contemporaneous with SARS-CoV-2 infection might boost antiviral immunity and improve patient outcomes. We investigated, among previously unvaccinated patients, whether vaccination (with the Pfizer, Moderna, or J&J vaccines) during the week before or after a positive COVID-19 test was associated with altered 30-day patient outcomes. METHODS: Using a deidentified longitudinal EHR repository, we selected all previously unvaccinated adults who initially tested positive for SARS-CoV-2 between December 11, 2020 (the date of vaccine emergency use approval) and December 19, 2021...

Magnetic resonance spectroscopy (MRS) is one of the few non-invasive imaging modalities capable of making neurochemical and metabolic measurements in vivo . Traditionally, the clinical utility of MRS has been narrow. The most common use has been the "single-voxel spectroscopy" variant to discern the presence of a lactate peak in the spectra in one location in the brain, typically to evaluate for ischemia in neonates. Thus, the reduction of rich spectral data to a binary variable has not classically necessitated much signal processing...

BACKGROUND: Atrial fibrillation (AF) recurrence during the blanking period is under investigated. With the rise of smartphone-based electrocardiogram (ECG) monitoring, there's potential for better prediction and understanding of AF recurrence trends. OBJECTIVES: In this study we hypothesize that AF burden derived from a single-lead Smartphone ECG during the blanking period predicts recurrence of atrial arrhythmias after ablation. METHODS: 630 patients with persistent AF undergoing ablation were included from the DECAAF II (Effect of MRI-Guided Fibrosis Ablation vs Conventional Catheter Ablation on Atrial Arrhythmia Recurrence in Patients With Persistent Atrial Fibrillation) trial...

INTRODUCTION: Treatment of refractory pulmonary arterial hypertension (PAH) is challenging and rarely the focus of reviews. The purpose of this review is to discuss current treatment options of refractory PAH, along with the state of research of several new medications. AREAS COVERED: We conducted a comprehensive PubMed search on the relevant literature on treating PAH, with a focus on approved and investigational interventions for high-risk patients. Our strategy used keywords 'Treatment' AND 'Pulmonary Hypertension,' without date restrictions, ensuring a thorough survey of available literature for our review...

BACKGROUND: The advent of direct-acting antivirals has helped to increase the safe utilization of organs from hepatitis C virus positive (HCV+) donors. However, the outcomes of heart transplantation (HT) using an HCV+ donor are unclear in recipients with underlying liver disease represented by an elevated model for end-stage liver disease excluding international normalized ratio (MELD-XI). METHODS: The United Network of Organ Sharing database was queried from Jan 2016 to Dec 2021...
