Performance of magnetic resonance elastography in primary sclerosing cholangitis.
Liver stiffness (LS) measured by magnetic resonance elastography (MRE) is emerging as an important biomarker in chronic liver diseases. We examined the diagnostic performance of MRE, factors associated with an increased LS and the prognostic value of LS as measured by MRE among patients with primary sclerosing cholangitis (PSC). ⋯ Magnetic resonance elastography is able to detect cirrhosis with high specificity and an alkaline phosphatase <1.5 times the upper limit of normal makes the presence of advanced LS unlikely. Moreover, LS obtained by MRE is predictive of hepatic decompensation in PSC.

Elevated H2 O2 levels in trinitrobenzene sulfate-induced colitis rats contributes to visceral hyperalgesia through interaction with the transient receptor potential ankyrin 1 cation channel.
Inflammatory bowel disease is associated with chronic abdominal pain. Transient receptor potential ankyrin 1 (TRPA1) is a well-known pain sensor expressed in primary sensory neurons. Recent studies indicate that reactive oxygen species such as hydrogen peroxide (H2 O2 ) may activate TRPA1. ⋯ These results suggest that H2 O2 content of the colonic tissue is increased in the early stage of TNBS-induced colitis. The increased H2 O2 content may contribute to the visceral hyperalgesia by activating TRPA1.

Review Meta AnalysisSafety and efficacy of antibiotic prophylaxis in patients undergoing elective laparoscopic cholecystectomy: A systematic review and meta-analysis.
Owing to persistent controversy regarding the use of routine antibiotic prophylaxis in patients undergoing elective laparoscopic cholecystectomy and the availability of several new randomized controlled trials (RCTs), we conducted an up-to-date meta-analysis to provide the best current evidence. The aim of the article is to evaluate the safety and efficacy of routine antibiotic prophylaxis in low-risk patients undergoing elective laparoscopic cholecystectomy. ⋯ Antibiotic prophylaxis is safe and effective in reducing surgical site infections and global infections during hospitalization or after discharge, and postoperative length of hospital stay in low-risk patients undergoing elective laparoscopic cholecystectomy.

The development of a non-invasive model to predict the presence of non-alcoholic steatohepatitis in patients with non-alcoholic fatty liver disease.
Non-alcoholic steatohepatitis (NASH) is an advanced and aggressive form of non-alcoholic fatty liver disease (NAFLD), which remains difficult to diagnose without a liver biopsy. Hyperferritinemia has increasingly been associated with the presence of NASH. Hence, we sought to explore the relationship between ferritin and NASH and to develop a composite model based on ferritin to predict the presence of NASH. ⋯ While higher ferritin was significantly associated with NASH, ferritin alone lacked diagnostic accuracy to predict NASH. However, incorporating several easily obtainable variables with ferritin allowed the construction of a novel scoring system that can be easily applied in the clinical setting to guide management of NAFLD.

α-fetoprotein levels after interferon therapy predict regression of liver fibrosis in patients with sustained virological response.
Eradicating chronic hepatitis C virus (HCV) infection improves liver fibrosis and reduces hepatocellular carcinoma (HCC) incidence in chronic HCV patients. We evaluated the relationship between fibrosis regression, as assessed by sequential biopsies, and clinical factors of patients with sustained virological response (SVR). ⋯ Lower post-treatment AFP levels and HCV genotype 2 significantly correlated with liver fibrosis regression after SVR.
