The glucagon-like peptide-1 (GLP-1) receptor agonists (RAs) exenatide and lixisenatide reduce cholecystokinin (CCK)-induced gallbladder emptying in healthy subjects. It is unknown if all GLP-1 RAs share this effect; therefore, the effect of the GLP-1 RA albiglutide on gallbladder function was assessed. In this randomized, double-blind, 2-way crossover study, a single dose of subcutaneous albiglutide 50 mg or placebo was administered to 17 healthy subjects, and CCK-induced gallbladder contractility was measured by ultrasonography...

BACKGROUND: Arterial stiffness is a principal cardiovascular risk factor. Metabolic syndrome (MetS) is a predisposing factor to arterial stiffness and persistent MetS circumstances can deteriorate the arterial stiffness severity. Low concentrations of plasma ghrelin are meticulously connected to arterial stiffness. This work targeted to judge the relationship between plasma ghrelin levels and intima-media thickness (IMT) and brachial-ankle pulse wave velocity (baPWV) as markers of arterial stiffness and inflammatory markers and in Saudi subjects with MetS...

INTRODUCTION: Liver hemangiomas are the most common benign tumors of the liver. Most are asymptomatic and are found accidentally by ultrasonography, computed tomography or magnetic resonance imaging of the abdomen. Liver hemangiomas usually do not need any treatment. Nevertheless, symptomatic, giant hemangiomas can be indicated for surgery, embolization or thermoablation. The aim of this study was to define based on our own experience and on the literature when and what treatment option should be indicated in patients suffering from liver hemangioma...
