Triple-phase abdominal computed tomography for detecting spontaneous portopulmonary shunts in cirrhotic patients.

Background And Aim: Data on prevalence of portopulmonary shunts (PPS) are quite limited. Most studies have used cineportography or echocardiography for diagnosis. Only few recent case reports have reported the use of computed tomography (CT) for identification of PPS.

Adenoma detection rate is not influenced by full-day blocks, time, or modified queue position.

Background: Recent studies have shown the adenoma detection rate (ADR) to decrease from endoscopist fatigue.

Objective: Our primary objective was to evaluate the afternoon ADR in half-day versus full-day blocks. Secondary objectives were to determine whether time or complexity of prior procedures (modified queue position) influence ADR.

Association of body mass index and lipid profiles: evaluation of a broad spectrum of body mass index patients including the morbidly obese.

Prior epidemiologic studies have shown that increasing body mass index (BMI) is associated with higher total cholesterol and low-density lipoprotein cholesterol (LDL). However, these studies were limited by underrepresentation of obese subjects. The aim of this study was to determine whether there is an association between BMI and lipid profiles in a population of patients with a broad spectrum of BMI values.
