N‐myc downstream‐regulated gene 2 inhibits human cholangiocarcinoma progression and is regulated by leukemia inhibitory factor/MicroRNA‐181c negative feedback pathway

Jiabei Wang, Changming Xie, Shangha Pan, Yingjian Liang, Jihua Han, Yaliang Lan, Jing Sun, Keyu Li, Boshi Sun, Guangchao Yang, Huawen Shi, Yuejin Li, Ruipeng Song, Xirui Liu, Mingxi Zhu, Dalong Yin, Huanlai Wang, Xuan Song, Zhaoyang Lu, Hongchi Jiang, Tongsen Zheng, Lianxin Liu – 17 August 2016 – Increasing evidence supports a role for N‐myc downstream‐regulated gene 2 (NDRG2) deregulation in tumorigenesis. We investigated the roles and mechanisms of NDRG2 in human cholangiocarcinoma (CCA) progression.

Patient‐reported barriers are associated with lower hepatocellular carcinoma surveillance rates in patients with cirrhosis

Sherean Farvardin, Jaimin Patel, Maleka Khambaty, Olutola A. Yerokun, Huram Mok, Jasmin A. Tiro, Adam C. Yopp, Neehar D. Parikh, Jorge A. Marrero, Amit G. Singal – 17 August 2016 – Over 20% of patients with cirrhosis are nonadherent with hepatocellular carcinoma (HCC) surveillance recommendations; however, few studies have evaluated the impact of patient‐level factors on surveillance receipt.

Evaluation of proton pump inhibitor use on treatment outcomes with ledipasvir and sofosbuvir in a real‐world cohort study

Elliot B. Tapper, Bruce R. Bacon, Michael P. Curry, Douglas T. Dieterich, Steven L. Flamm, Lauren E. Guest, Kris V. Kowdley, Yoori Lee, Naoky C. Tsai, Zobair M. Younossi, Nezam H. Afdhal – 17 August 2016 – Many patients with chronic hepatitis C virus (HCV) are on prolonged proton‐pump inhibitor (PPI) therapy and wish to remain on PPI therapy once treatment for HCV starts. A preliminary report recently suggested decrease rates of sustained virological response (SVR) for patients taking concomitant PPI and ledipasvir/sofosbuvir (LDV/SOF).

Hepatitis C virus transmission among human immunodeficiency virus‐infected men who have sex with men: Modeling the effect of behavioral and treatment interventions

Luisa Salazar‐Vizcaya, Roger D. Kouyos, Cindy Zahnd, Gilles Wandeler, Manuel Battegay, Katharine Elizabeth Anna Darling, Enos Bernasconi, Alexandra Calmy, Pietro Vernazza, Hansjakob Furrer, Matthias Egger, Olivia Keiser, Andri Rauch, the Swiss HIV Cohort Study – 17 August 2016 – The incidence of hepatitis C virus (HCV) infections among human immunodeficiency virus (HIV)‐infected men who have sex with men has increased in recent years and is associated with high‐risk sexual behavior.

Wnt signaling regulates hepatobiliary repair following cholestatic liver injury in mice

Hirohisa Okabe, Jing Yang, Kyle Sylakowski, Mladen Yovchev, Yoshitaka Miyagawa, Shanmugam Nagarajan, Maria Chikina, Michael Thompson, Michael Oertel, Hideo Baba, Satdarshan P Monga, Kari Nichole Nejak‐Bowen – 17 August 2016 – Hepatic repair is directed chiefly by the proliferation of resident mature epithelial cells. Furthermore, if predominant injury is to cholangiocytes, the hepatocytes can transdifferentiate to cholangiocytes to assist in the repair and vice versa, as shown by various fate‐tracing studies. However, the molecular bases of reprogramming remain elusive.

Sirtuin 2 aggravates postischemic liver injury by deacetylating mitogen‐activated protein kinase phosphatase‐1

Jie Wang, Hyoung‐Won Koh, Lu Zhou, Ui‐Jin Bae, Hwa‐Suk Lee, In Hyuk Bang, Sun‐O Ka, Seon‐Hee Oh, Eun Ju Bae, Byung‐Hyun Park – 17 August 2016 – Sirtuin 2 (Sirt2) is known to negatively regulate anoxia‐reoxygenation injury in myoblasts. Because protein levels of Sirt2 are increased in ischemia‐reperfusion (I/R)‐injured liver tissues, we examined whether Sirt2 is protective or detrimental against hepatic I/R injury. We overexpressed Sirt2 in the liver of C57BL/6 mice using a Sirt2 adenovirus.

Longterm outcomes of stent placement for hepatic venous outflow obstruction in adult liver transplantation recipients

Hee Ho Chu, Nam‐Joon Yi, Hyo‐Cheol Kim, Kwang‐Woong Lee, Kyung‐Suk Suh, Hwan Jun Jae, Jin Wook Chung – 12 August 2016 – The purpose of this study was to evaluate the longterm outcomes of stent placement for a hepatic venous outflow obstruction in adult liver transplantation recipients. From June 2002 to March 2014, 23 patients were confirmed to have a hepatic venous outflow obstruction after liver transplantation (18 of 789 living donors [2.3%] and 5 of 449 deceased donors [1.1%]) at our institute.

Impact of donor‐recipient genetic relationship on outcome of living donor liver transplantation

Mahmoud Abdelwahab Ali, Mohamed Morsi Elshobari, Tarek Salah, Al‐Refaey Kandeel, Ahmad Mohammad Sultan, Ahmad Nabieh Elghawalby, Ahmed Shehta, Usama Elsayed, Omar Fathy, Amr Yassen, Mohamed Abdel Wahab – 12 August 2016 – Living donor liver transplantation (LDLT) is a valuable option for expanding the donor pool, especially in localities where deceased organ harvesting is not allowed. In addition, rejection rates were found to be lower in LDLT, which is attributed to the fact that LDLT is usually performed between relatives.
