Role of videourodynamics in the identification of causes of lower urinary tract symptoms and low uroflow in young men.

Introduction: The etiology of lower urinary tract symptoms (LUTS) is multifactorial with causes attributed either to the dysfunction of the bladder or its outlet. Although the etiologies are well studied in aged men, very limited research trials are available in young men with LUTS. Most of the time young men presenting with chronic irritative or obstructive symptoms are labeled with chronic prostatitis or prostatodynia and are treated empirically.

Intragastric balloons in high-risk obese patients in a Brazilian center: initial experience.

Objective: to assess the short-term efficacy, tolerance and complications in high-risk morbidly obese patients treated with an intragastric balloon as a bridge for surgery.

Methods: we conducted a post-hoc analysis study in a Brazilian teaching hospital from 2010 to 2014, with 23 adult patients with a BMI of 48kg/m2, who received a single intragastric air or liquid balloon. We defined efficacy as 10% excess weight loss, and complications, as adverse events consequent to the intragastric balloon diagnosed after the initial accommodative period.

Elipse, the first procedureless gastric balloon for weight loss: a prospective, observational, open-label, multicenter study.

 Conventional gastric balloons for weight loss require endoscopy for placement and removal. The Elipse device is swallowed, resides in the stomach for 4 months, and is then expelled. The objectives of this study were to assess the safety of Elipse and to measure its effects on weight loss, metabolic parameters, and quality of life.

Prediction of Low versus High Recurrence Scores in Estrogen Receptor-Positive, Lymph Node-Negative Invasive Breast Cancer on the Basis of Radiologic-Pathologic Features: Comparison with Oncotype DX Test Recurrence Scores.

Purpose To review mammographic, ultrasonographic (US), and magnetic resonance (MR) imaging features and pathologic characteristics of estrogen receptor (ER)-positive, lymph node-negative invasive breast cancer and to determine the relationship of these characteristics to Oncotype DX (Genomic Health, Redwood City, Calif) test recurrence scores (ODRS) for breast cancer recurrence. Materials and Methods This institutional review board-approved retrospective study was performed in a single large academic medical center. The study population included patients with ER-positive, lymph node-negative invasive breast cancer who underwent genomic testing from January 1, 2009, to December 31, 2013.

Elipse™, a Procedureless Gastric Balloon for Weight Loss: a Proof-of-Concept Pilot Study.

Background: Endoscopic gastric balloons have been used effectively as weight loss devices for decades, but the requirement for endoscopy and sedation poses several limitations. The goal of this pilot study was to evaluate the safety and performance of a prototype version of Elipse™, a procedureless gastric balloon.

Methods: Eight patients (mean BMI = 31.

Hepatic arterial chemoembolization using drug-eluting beads in gastrointestinal neuroendocrine tumor metastatic to the liver.

Purpose: This study was designed to evaluate short (<3 months) and intermediate-term (>3 months) follow-up in patients with metastatic neuroendocrine tumor to the liver who underwent hepatic arterial chemoembolization with drug-eluting beads at a single institution.

Methods: Institutional review board approval was obtained for this retrospective review. All patients who were treated with 100-300 or 300-500 μm drug-eluting LC Beads (Biocompatibles, UK) preloaded with doxorubicin (range, 50-100 mg) for GI neuroendocrine tumor metastatic to the liver from June 2004 to June 2009 were included.

Pharmacologic inhibition of the anaphase-promoting complex induces a spindle checkpoint-dependent mitotic arrest in the absence of spindle damage.

Microtubule inhibitors are important cancer drugs that induce mitotic arrest by activating the spindle assembly checkpoint (SAC), which, in turn, inhibits the ubiquitin ligase activity of the anaphase-promoting complex (APC). Here, we report a small molecule, tosyl-L-arginine methyl ester (TAME), which binds to the APC and prevents its activation by Cdc20 and Cdh1. A prodrug of TAME arrests cells in metaphase without perturbing the spindle, but nonetheless the arrest is dependent on the SAC.

Disease-associated mutations affect GPR56 protein trafficking and cell surface expression.

Bilateral frontoparietal polymicrogyria (BFPP) is a congenital brain malformation resulting in irregularities on the surface of the cortex, where normally convoluted gyri are replaced by numerous (poly) and noticeably smaller (micro) gyri. Individuals with BFPP suffer from epilepsy, mental retardation, language impairment and motor developmental delay. Mutations in the gene-encoding G protein-coupled receptor 56 (GPR56) cause BFPP; however, it remains unclear how these mutations affect GPR56 function.
