George N. Ioannou, Christopher L. Bryson, Noel S. Weiss, Richard Miller, John D. Scott, Edward J. Boyko – 24 April 2012 – Cirrhosis is a leading cause of death among patients infected with human immunodeficiency virus (HIV). We sought to determine risk factors for and time trends in the prevalence of cirrhosis, decompensated cirrhosis, and hepatocellular carcinoma (HCC) among patients diagnosed with HIV who received care in the Veterans Affairs (VA) health care system nationally between 1996 and 2009 (n = 24,040 in 2009).

James J. Pomposelli, Assanee Tongyoo, Christoph Wald, Elizabeth A. Pomfret – 24 April 2012 – The estimation of the standard liver volume (SLV) is an important component of the evaluation of potential living liver donors and the surgical planning for resection for tumors. At least 16 different formulas for estimating SLV have been published in the worldwide literature. More recently, several proprietary software‐assisted image postprocessing (SAIP) programs have been developed to provide accurate volume measurements based on the actual anatomy of a specific patient.

Norman, Aftab A. Ansari, Xiao‐Song He, Ross L. Coppel, M. Eric Gershwin – 24 April 2012 – Dominant negative form of transforming growth factor beta receptor type II (dnTGFβRII) mice, expressing a dominant negative form of TGFβ receptor II under control of the CD4 promoter, develop autoimmune colitis and cholangitis.

Benjamin Krämer, Christian Körner, Moritz Kebschull, Andreas Glässner, Marianne Eisenhardt, Hans‐Dieter Nischalke, Michael Alexander, Tilman Sauerbruch, Ulrich Spengler, Jacob Nattermann – 24 April 2012 – Natural killer (NK) cells play a role in the early control and natural course of hepatitis C virus (HCV) infection. NK cell function is regulated by a multitude of receptors, including activating NKp46 receptor. However, reports on NKp46 in hepatitis C are controversial.

Dahee Choi, Kyoung‐Jin Oh, Hye‐Sook Han, Young‐Sil Yoon, Chang‐Yun Jung, Seong‐Tae Kim, Seung‐Hoi Koo – 24 April 2012 – Postprandial insulin plays a critical role in suppressing hepatic glucose production to maintain euglycemia in mammals. Insulin‐dependent activation of protein kinase B (Akt) regulates this process, in part, by inhibiting FoxO1‐dependent hepatic gluconeogenesis by direct phosphorylation and subsequent cytoplasmic exclusion.

Monika Ferlitsch, Thomas Reiberger, Matthias Hoke, Petra Salzl, Bernadette Schwengerer, Gregor Ulbrich, Berit Anna Payer, Michael Trauner, Markus Peck‐Radosavljevic, Arnulf Ferlitsch – 24 April 2012 – von Willebrand factor antigen (vWF‐Ag) is elevated in patients with liver cirrhosis, but the clinical significance is unclear. We hypothesized that vWF‐Ag levels may correlate with portal pressure, measured by hepatic venous pressure gradient (HVPG), and predict clinically significant portal hypertension (CSPH; HVPG ≥10 mmHg), decompensation and mortality.
