Over the past 2 decades, nonalcoholic fatty liver disease (NAFLD) has grown from a relatively unknown disease to the most common cause of CLD in the world. In fact, 25% of the world's population is currently thought to have NAFLD. Non-alcoholic steatohepatitis (NASH) is the subtype of NAFLD that can progress to cirrhosis, hepatocellular carcinoma, and death. NAFLD and NASH are found in not only adults-there is a high prevalence in children and adolescents. Due to NAFLD's close association with type 2 diabetes (T2DM) and obesity, the latest models predict the prevalence of NAFLD and NASH will increase, causing a tremendous clinical and economic burden and poor patient-reported outcomes. Nonetheless, there is no accurate non-invasive method to detect NASH and treatment is limited to life style modifications. To examine the state of NAFLD among different regions and understand the global trajectory of this disease, an international group of experts came together during 2017 AASLD Global NAFLD Forum. We provide a summary of this forum and an assessment of the current state of NAFLD and NASH worldwide. This article is protected by copyright. All rights reserved.

Perioperative use of terlipressin abrogates the early postoperative decline in renal function of patients who have chronic liver disease and undergo liver transplantation without any detrimental effect on hepatosplanchnic gas exchange and lactate metabolism.

Gastroscopy and colonoscopy are standard practice for diagnosing upper gastrointestinal and colonic diseases. Sedation improves tolerance of the endoscopic procedures, but may be responsible for about 50% of the complication rate of the examination. Data from countries of the five continents regarding the rate of using sedation for gastrointestinal endoscopy are rare. We performed a literature search (PubMed) to identify published national or international studies and summarize data on the rate of using sedation for diagnostic gastrointestinal endoscopic procedures in countries of Europe, North America, Asia, Africa and Australia. In continents where data were not available, we used mailed questionnaires to endoscopy centers in countries of these continents. Our data indicate that the use of sedation for diagnostic gastrointestinal endoscopy is high in North America and Australia, but varies considerably among countries in Europe, Asia and Africa.

The aim of this position statement is to reinforce the key points of hygiene in digestive endoscopy. The present article details the minimum hygiene requirements for reprocessing of endoscopes and endoscopic devices, regardless of the reprocessing method (automated washer-disinfector or manual cleaning) and the endoscopy setting (endoscopy suite, operating room, elective or emergency procedures). These minimum requirements are mandatory for patient safety. Both advanced diagnostic and therapeutic endoscopies should be carried out in an environment that is safe for patients and staff. Particular attention is given to contaminants. Procedural errors in decontamination, defective equipment, and failure to follow disinfection guidelines are major factors contributing to transmission of infection during endoscopy. Other important risk factors include inadequate cleaning, use of older endoscopes with surface and working channel irregularities, and contamination of water bottles or irrigating solutions. Infections by multidrug-resistant organisms have become an increasing problem in health-care systems worldwide. Since 2010, outbreaks of multidrug-resistant bacteria associated with endoscopic retrograde cholangiopancreatography have been reported from the USA, France, Germany, and The Netherlands. In many endoscopy units in Asia and the Middle East, reprocessing procedures have lagged behind those of Western countries for cultural reasons or lack of financial resources. This inconsistency in standards is now being addressed, and the World Endoscopy Organization has prepared this position statement to highlight key points for quality assurance in any endoscopy unit in any country.
