Utilization of Non-Gated Chest Computed Tomography Scans in Predicting Acute Coronary Occlusion in Out-of-Hospital Cardiac Arrest.

Coronary artery disease is thought to be responsible for up to 60%-80% of out-of-hospital cardiac arrests. The utility of Computed Tomography (CT) chest when it comes to identifying acute coronary occlusion in patients following an arrest has not been studied. We evaluated whether myocardial perfusion on a contrast-enhanced chest CT performed for a non-cardiac cause can predict culprit coronary occlusion as the cause of cardiac arrest and if the absence of a perfusion defect can exclude an ischemic etiology.

Adrenal cavernous hemangioma: A rare tumor that mimics adrenal cortical carcinoma.

Background: Adrenal cavernous hemangioma is a rare tumor with only 60 cases previously reported. The aim of this study was to determine the frequency and clinical significance of adrenal cavernous hemangioma at our institution.

Methods: A retrospective review of consecutive patients undergoing adrenalectomy from 1994 to 2018 was completed to determine the frequency of cavernous hemangioma, characterize the clinical presentation, imaging and pathologic features and review the operative management and outcome.

Selective nonoperative management of abdominal gunshot wounds with isolated solid organ injury.

Objective: To review selective nonoperative management (SNOM) of gunshot wound (GSW) patients with isolated abdominal solid organ injury.

Methods: Patients who sustained isolated solid organ injury secondary to GSW from 2003 to 2014 were studied. The use of SNOM over time was analyzed, and comparisons of initial SNOM and operative management (OM) groups were performed.

Conversion of ammonia-pretreated switchgrass to biofuel precursors by bacterial-fungal consortia under solid-state and submerged-state cultivation.

Aim: The aim of this study was to develop and evaluate bacterial-fungal communities to deconstruct switchgrass to biofuel precursors.

Methods And Results: Bacterial-fungal consortia, mesophilic (25°C) and thermophilic (50°C), were enriched from switchgrass bales from which enzyme mixtures were used to deconstruct delignified switchgrass (DSG). The bacterial-fungal consortia were able to produce enzymes including endoglucanase, exoglucanase, β-glucosidase, xylanase, xylosidase and pectinase to convert DSG to soluble carbohydrates.

Tumors and Tumorlike Conditions of the Anal Canal and Perianal Region: MR Imaging Findings.

Tumors and tumorlike conditions of the anus and perianal region originate from the anal canal and anal margin or result from direct extension of tumors from adjacent organs. The anatomy of the anal canal is complex, and its different histologic characteristics can lead to diverse pathologic conditions. The anal canal extends from the anorectal junction to the anal verge.
