Pulmonary sarcoidosis is a rare heterogeneous lung disease of unknown aetiology, with limited treatment options. Phenotyping relies on clinical testing including visual scoring of chest radiographs. Objective radiomic measures from high-resolution computed tomography (HRCT) may provide additional information to assess disease status. As the first radiomics analysis in sarcoidosis, we investigate the potential of radiomic measures as biomarkers for sarcoidosis, by assessing 1) differences in HRCT between sarcoidosis subjects and healthy controls, 2) associations between radiomic measures and spirometry, and 3) trends between Scadding stages.
A standard lung template could improve population-level analyses for computed tomography (CT) scans of the lung. We develop a fully automated preprocessing pipeline for image analysis of the lungs using updated methodologies and R software that results in the creation of a standard lung template. We apply this pipeline to CT scans from a sarcoidosis population, exploring the influence of registration on radiomic analyses

Children with complex medical problems who require anesthesia are known to be at risk for acute adverse physiologic events related to anesthesia. The risks of anesthesia include short- and long-term psychological and neurobehavioral issues. Magnetic …
Federal regulations governing access to levonorgestrel (LNG) emergency contraception (EC) have evolved since its introduction in the 1990s. LNG EC was initially available by prescription only, but is now available over-the-counter to consumers of all …
BACKGROUND In patients with atrial fibrillation or flutter, a left atrial appendage ejection velocity measured via transesophageal echocardiography equal to or less than 40 cm/sec has been shown to correlate with an increased risk of developing left …
Type 1 diabetes (T1D) is an autoimmune proinflammatory disease with no effective intervention. A major obstacle in developing new immunotherapies for T1D is the lack of means for monitoring immune responsiveness to experimental therapies. The …
