Robert P. Myers, Hude Quan, James N. Hubbard, Abdel Aziz M. Shaheen, Gilaad G. Kaplan – 28 January 2009 – Risk‐adjusted health outcomes are often used to measure the quality of hospital care, yet the optimal approach in patients with liver disease is unclear. We sought to determine whether assessments of illness severity, defined as risk for in‐hospital mortality, vary across methods in patients with cirrhosis. We identified 258,731 patients with cirrhosis hospitalized in the Nationwide Inpatient Sample between 2002 and 2005.

Giovanni Musso, Roberto Gambino, Giovanni Pacini, Gianfranco Pagano, Marilena Durazzo, Maurizio Cassader – 28 January 2009 – Genetic factors underlying the association of NAFLD with diabetes and atherosclerosis are unknown. Recent human studies suggest transcription factor 7–like 2 (TCF7L2) polymorphism predisposes to diabetes through modulation of β‐cell function and modulates lipid levels in familial dyslipidemia. Emerging experimental evidence connects TCF7L2 to adipocyte metabolism and lipid homeostasis, as well.

Jane A. Byrne, Sandra S. Strautnieks, Gudrun Ihrke, Franco Pagani, A.S. Knisely, Kenneth J. Linton, Giorgina Mieli‐Vergani, Richard J. Thompson – 28 January 2009 – The gene encoding the human bile salt export pump (BSEP), ABCB11, is mutated in several forms of intrahepatic cholestasis. Here we classified the majority (63) of known ABCB11 missense mutations and 21 single‐nucleotide polymorphisms (SNPs) to determine whether they caused abnormal ABCB11 pre‐messenger RNA splicing, abnormal processing of BSEP protein, or alterations in BSEP protein function.

Edward E. Cable, Patricia D. Finn, Jeffrey W. Stebbins, Jinzhao Hou, Bruce R. Ito, Paul D. van Poelje, David L. Linemeyer, Mark D. Erion – 28 January 2009 – Non‐alcoholic fatty liver disease (NAFLD) is one of the most common forms of chronic liver disease, with a prevalence ranging from 10% to 30%. The use of thyroid hormone receptor (TR) agonists for the treatment of NAFLD has not been considered viable because thyroid hormones increase free fatty acid (FFA) flux from the periphery to the liver, induce hepatic lipogenesis, and therefore could potentially cause steatosis.

Roniel Cabrera, Miguel Ararat, Consuelo Soldevila‐Pico, Lisa Dixon, Jen‐Jung Pan, Roberto Firpi, Victor Machicao, Cynthia Levy, David Nelson, Giuseppe Morelli – 28 January 2009 – In transplant recipients transplanted for hepatitis C, presentation of abnormal transaminases can herald the presentation of recurrent hepatitis C, cellular rejection, or both. Given the sometimes ambiguous histology with these 2 entities, the ability to distinguish them is of great importance because misinterpretation can potentially affect graft survival.

Henry L. Y. Chan – 28 January 2009

Judith M. Gottwein, Troels K. H. Scheel, Tanja B. Jensen, Jacob B. Lademann, Jannick C. Prentoe, Maria L. Knudsen, Anne M. Hoegh, Jens Bukh – 28 January 2009 – Six major hepatitis C virus (HCV) genotypes and numerous subtypes have been described, and recently a seventh major genotype was discovered. Genotypes show significant molecular and clinical differences, such as differential response to combination therapy with interferon‐α and ribavirin. Recently, HCV research has been accelerated by cell culture systems based on the unique growth capacity of strain JFH1 (genotype 2a).

Zhaoli Sun, Xiuying Zhang, Jayme E. Locke, Qizhi Zheng, Shingo Tachibana, Anna Mae Diehl, George Melville Williams – 28 January 2009 – Despite major histocompatibility complex incompatibility, liver transplants from Lewis rats to dark agouti (DA) rats survive indefinitely without immunosuppression, and the studies we report sought the mechanism(s) responsible for this. At 1 year, most of the liver reacted positively to host anti‐DA antibody. When small (50%) grafts were transplanted, recruitment was more rapid because most of the organ assumed the host phenotype at 3 months.

Darrell H. G. Crawford, Therese L. Murphy, Louise E. Ramm, Linda M. Fletcher, Andrew D. Clouston, Gregory J. Anderson, V. Nathan Subramaniam, Lawrie W. Powell, Grant A. Ramm – 28 January 2009 – Diagnosing the presence of cirrhosis is crucial for the management of patients with C282Y hereditary hemochromatosis (HH). HH patients with serum ferritin >1,000 μg/L are at risk of cirrhosis; however, the majority of these patients do not have cirrhosis.
