Clostridium difficile infection in hospitalized liver transplant patients: A nationwide analysis
Muhammad Ali, Ashwin N. Ananthakrishnan, Shahryar Ahmad, Nilay Kumar, Gagan Kumar, Kia Saeian – 14 April 2012 – The incidence of Clostridium difficile infection (CDI) is increasing among hospitalized patients. Liver transplantation (LT) patients are at higher risk for acquiring CDI. Small, single‐center studies (but no nationwide analyses) have assessed this association. We used the Nationwide Inpatient Sample of the Healthcare Cost and Utilization Project (2004‐2008) for this retrospective, cross‐sectional study.
Pentoxifylline decreases oxidized lipid products in nonalcoholic steatohepatitis: New evidence on the potential therapeutic mechanism
Claudia O. Zein, Rocio Lopez, Xiaoming Fu, John P. Kirwan, Lisa M. Yerian, Arthur J. McCullough, Stanley L. Hazen, Ariel E. Feldstein – 13 April 2012 – Pentoxifylline (PTX) improved the histological features of nonalcoholic steatohepatitis (NASH) in a recent randomized placebo‐controlled trial. However, the underlying mechanism responsible for the beneficial effects of PTX in NASH remains unidentified. A key role of lipid oxidation in the pathogenesis and progression of NASH has been established. PTX is known to decrease free‐radical‐mediated oxidative stress and inhibit lipid oxidation.
Intraductal papillary neoplasm of the bile duct: A biliary equivalent to intraductal papillary mucinous neoplasm of the pancreas?
Flavio G. Rocha, Hwajeong Lee, Nora Katabi, Ronald P. DeMatteo, Yuman Fong, Michael I. D'Angelica, Peter J. Allen, David S. Klimstra, William R. Jarnagin – 13 April 2012 – Intraductal papillary neoplasm of the bile duct (IPNB) is a variant of bile duct carcinoma characterized by intraductal growth and better outcome compared with the more common nodular‐sclerosing type. IPNB is a recognized precursor of invasive carcinoma, but its pathogenesis and natural history are ill‐defined. This study examines the clinicopathologic features and outcomes of IPNB.
Primary biliary cirrhosis and cancer risk: A systematic review and meta‐analysis
Yan Liang, Zaixing Yang, Renqian Zhong – 13 April 2012 – Several studies have indicated that primary biliary cirrhosis (PBC) may be associated with increased risk of some cancers, but the results are controversial. We conducted a systematic review of studies to examine the association of PBC with cancer risk by meta‐analysis. We searched the PubMed and EMBASE databases for English‐language studies published before November 2011. Studies were included if they reported relative risk estimates with 95% confidence intervals (CIs) or related data for the association between PBC and cancer risk.
Race‐ and gender‐related variation in natural killer p46 expression associated with differential anti‐hepatitis c virus immunity
Lucy Golden‐Mason, Amy E.L. Stone, Kiran M. Bambha, Linling Cheng, Hugo R. Rosen – 13 April 2012 – Major racial and gender differences have been documented in the natural history and treatment responses of chronic hepatitis C virus (HCV) infection; however, distinct mechanisms have remained enigmatic. We hypothesized that racial‐ and gender‐related differences in natural killer (NK) cell populations may explain altered natural history and treatment responses.
Hydrogen‐rich water prevents progression of nonalcoholic steatohepatitis and accompanying hepatocarcinogenesis in mice
Daisuke Kawai, Akinobu Takaki, Atsuko Nakatsuka, Jun Wada, Naofumi Tamaki, Tetsuya Yasunaka, Kazuko Koike, Ryuichiro Tsuzaki, Kazuyuki Matsumoto, Yasuhiro Miyake, Hidenori Shiraha, Manabu Morita, Hirofumi Makino, Kazuhide Yamamoto – 13 April 2012 – Oxidative stress is a strong contributor to the progression from simple fatty liver to nonalcoholic steatohepatitis (NASH). Molecular hydrogen is an effective antioxidant that reduces cytotoxic reactive oxygen species.
Cardiovascular phenotype of nonalcoholic fatty liver disease: Hanging the paradigm about the role of distant toxic fat accumulation on vascular disease

Antagonism of sphingosine 1‐phosphate receptor 2 causes a selective reduction of portal vein pressure in bile duct‐ligated rodents
Yuko Kageyama, Hitoshi Ikeda, Naoko Watanabe, Masakazu Nagamine, Yoshika Kusumoto, Mitsuru Yashiro, Yumiko Satoh, Tatsuo Shimosawa, Koji Shinozaki, Tomoaki Tomiya, Yukiko Inoue, Takako Nishikawa, Natsuko Ohtomo, Yasushi Tanoue, Hiromitsu Yokota, Takatoshi Koyama, Kazuhiro Ishimaru, Yasuo Okamoto, Yoh Takuwa, Kazuhiko Koike, Yutaka Yatomi – 13 April 2012 – Sinusoidal vasoconstriction, in which hepatic stellate cells operate as contractile machinery, has been suggested to play a pivotal role in the pathophysiology of portal hypertension.
Tim‐3/galectin‐9 signaling pathway mediates T‐cell dysfunction and predicts poor prognosis in patients with hepatitis B virus‐associated hepatocellular carcinoma
Hang Li, Ke Wu, Kaixiong Tao, Libo Chen, Qichang Zheng, Xiaoming Lu, Jun Liu, Liang Shi, Chuanqiao Liu, Guobin Wang, Weiping Zou – 13 April 2012 – The interaction between T cell immunoglobulin‐ and mucin‐domain‐containing molecule (Tim‐3) expressed on T helper 1 (Th1) cells, and its ligand, galectin‐9, negatively regulates Th1‐mediated immune responses. However, it is poorly understood if and how the Tim‐3/galectin‐9 signaling pathway is involved in immune escape in patients with hepatocellular carcinoma (HCC).
