Observational StudySomatostatin analogue-induced pancreatic exocrine insufficiency in patients with neuroendocrine tumors: results of a prospective observational study.
Patients with advanced well-differentiated neuroendocrine tumours (Wd-NETs) are commonly treated with somatostatin analogues (SSAs). Some patients may develop SSA-related side effects such as pancreatic exocrine insufficiency (PEI). ⋯ This study demonstrated that PEI occurs at a higher rate than previously reported; clinicians need to diagnose and treat this SSA-related adverse-event which occurs in 1 in 4 patients with Wd-NETs treated with SSAs. Screening with FE1 in symtomatic patients is recommend.

ReviewAcute-on-chronic liver failure in chronic hepatitis B: an update.
Acute-on-chronic liver failure is a common pattern of end-stage liver disease in clinical practice and occurs frequently in patients with chronic hepatitis B or HBV-related cirrhosis. New progress in recent years leads to a better understanding of this disease. Areas covered: This review updates the current comprehensive knowledge about HBV-ACLF from epidemiological studies, experimental studies, and clinical studies and provide new insights into the definition, diagnostic criteria, epidemiology, nature history, pathogenesis, treatment and prognostication of HBV-ACLF. ⋯ Cell therapy is a promising alternative to LT, but requires validation and still has concern of long-term safety. Other medical therapies, such as nucleoside analogue, artificial liver supporting and glucocorticoid may improve survival in a specific subgroup. New scoring systems improve the accuracy of prognostication in HBV-ACLF, which is critical for early identification of candidates for LT.

ReviewDysplasia and colorectal cancer surveillance in inflammatory bowel disease.
Inflammatory bowel disease (IBD) patients are at an increased risk of developing colorectal cancer (CRC), a devastating complication of which intestinal dysplasia is the precursor. Considerable progress has been made to determine CRC risk in IBD, identification & management of dysplasia and preventative methods. Traditionally, surveillance colonoscopies with random colonic biopsies was used. ⋯ Expert commentary: The role of our strategies in modifying CRC risk needs further assessment. Future research should aim to fill knowledge gaps such as high quality evidence for Chromoendoscopy and development of molecular markers for dysplasia detection. Our ultimate goal would be to eliminate CRC and is possible by better understanding of key pathogenic mechanisms in IBD.

ReviewOmbitasvir and paritaprevir boosted with ritonavir and combined with dasabuvir for chronic hepatitis C.
Hepatitis C is a leading cause of cirrhosis and hepatocellular carcinoma responsible for almost 700,000 deaths worldwide annually. Until 2014, management of HCV infections was based on interferon alfa containing regimens, with efficacy of 40-70% and a high adverse event rate. Interferon-free therapeutic options improved sustained viral response (SVR) rate to >90% and safety profile to placebo-like levels. ⋯ Expert commentary: Combination of OBV/PTV/r±DSV±RBV provides SVR rate of about 95% and good safety profile even in patients with compensated liver cirrhosis and failure with previous therapy. Currently it should be of particular value in areas with a predominance of genotype 1b infections. Due to the complexity and risk of drug to drug interactions, it will probably be replaced in coming few years with pangenotypic combinations of next generation DAAs.
