https://www.selleckchem.com/products/jnj-42226314.html Gastroesophageal reflux disease (GERD) is one of the complications of bariatric operations that might affect the quality of life. We aim to perform a retrospective cohort study to determine the incidence of symptomatic GERD following different types of bariatric surgery and which operations are considered a contraindication of GERD. Besides, we are attempting to identify the risk factors of GERD after bariatric surgery. Medical records of 729 patients who had undergone bariatric operations between January 2010 and June 2019 at the Shamir (Assaf Harofeh) Medical Center were reviewed. There was a significant difference between the type of bariatric procedure and the incidence of GERD symptoms after the operation. The incidence of symptomatic GERD in patients who underwent sleeve gastrectomy (SG) was 39.9% (p = 0.0131). This was significantly higher compared to 16.4% following Roux-en-Y gastric bypass, 23.4% following laparoscopic adjustable gastric band, and 11% following one anastomosis gastric bypass. 1low study and symptomatic GERD patients preoperatively because of high levels of symptomatic GERD postoperatively. Asymptomatic reflux at contrast swallow study preoperatively could be considered a risk factor for GERD after the operation. More studies are needed to be performed on this subject with the addition of postoperative contrast swallow test and pH monitoring preoperatively and postoperatively.Aichi virus 1 (AiV-1) has been proposed as a causative agent of human gastroenteritis. In this study, raw, decanted, and treated wastewater samples from a wastewater treatment plant in an urban area of Dakar, Senegal, were collected. AiV-1 was detected in raw (70%, 14/20), decanted (68.4%, 13/19), and treated (59.3%, 16/27) samples, revealing a noticeable resistance of AiV-1 to chlorine-based treatment. Phylogenetic analysis revealed that all sequences clustered within genotype B. Our study presents the first report
