Anawin Sanguankeo, Sikarin Upala – 4 September 2018

Chhagan Bihari, Deepika Lal, Monika Thakur, Sukriti Sukriti, Dhananjay Mathur, Anupama G. Patil, Lovkesh Anand, Guresh Kumar, Shvetank Sharma, Shalini Thapar, Apurba Rajbongshi, Archana Rastogi, Anupam Kumar, Shiv K. Sarin – 4 September 2018 – Bone loss is common in advanced cirrhosis, although the precise mechanisms underlying bone loss in cirrhosis are unknown. We studied the profile and functionality of bone‐forming cells and bone‐building proteins in bone marrow (BM) of individuals with cirrhosis (n = 61) and individuals without cirrhosis as normal controls (n = 50).

Zobair M. Younossi, Radhika Tampi, Massoom Priyadarshini, Fatema Nader, Issah M. Younossi, Andrei Racila – 4 September 2018 – Nonalcoholic steatohepatitis (NASH) is the progressive form of nonalcoholic fatty liver disease. Our aim was to estimate the total economic burden of NASH and advanced NASH in the United States. We constructed lifetime Markov models for all stages of NASH and a separate model to specifically identify the increased burden of advanced NASH (fibrosis stage >3). The models comprised patients aged 18+, who moved through seven different health states.

Binita Kamath, Cara Mack – 4 September 2018

Jingwen Wang, Jianwen Chen, Yang Liu, Xianhuang Zeng, Mingcong Wei, Shaoshuai Wu, Qiushuang Xiong, Feifei Song, Xu Yuan, Yu Xiao, Yun Cao, Changyong Li, Lang Chen, Mingxiong Guo, Yun‐Bo Shi, Guihong Sun, Deyin Guo – 4 September 2018 – Hepatitis B virus (HBV) is a major risk factor for the development and progression of hepatocellular carcinoma. It has been reported that viral infection can interfere with cellular microRNA (miRNA) expression and participate in the pathogenesis of oncogenicity.

Zobair Younossi, Frank Tacke, Marco Arrese, Barjesh Chander Sharma, Ibrahim Mostafa, Elisabetta Bugianesi, Vincent Wai‐Sun Wong, Yusuf Yilmaz, Jacob George, Jiangao Fan, Miriam B. Vos – 4 September 2018 – Over the past 2 decades, nonalcoholic fatty liver disease (NAFLD) has grown from a relatively unknown disease to the most common cause of chronic liver disease in the world. In fact, 25% of the world’s population is currently thought to have NAFLD. Nonalcoholic steatohepatitis (NASH) is the subtype of NAFLD that can progress to cirrhosis, hepatocellular carcinoma (HCC), and death.

Aditya Ambade, Patrick Lowe, Karen Kodys, Donna Catalano, Benedek Gyongyosi, Yeonhee Cho, Arvin Iracheta‐Vellve, Adeyinka Adejumo, Banishree Saha, Charles Calenda, Jeeval Mehta, Eric Lefebvre, Pamela Vig, Gyongyi Szabo – 4 September 2018 – Kupffer cell and macrophage (MØ) activation contributes to steatosis, inflammation, and fibrosis in alcoholic liver disease (ALD).

Maria Eugenia Inzaugarat, Casey D. Johnson, Theresa Maria Holtmann, Matthew D. McGeough, Christian Trautwein, Bettina G. Papouchado, Robert Schwabe, Hal M. Hoffman, Alexander Wree, Ariel E. Feldstein – 4 September 2018 – The NLR family pyrin domain‐containing 3 (NLRP3) inflammasome plays an important role in liver fibrosis (LF) development. However, the mechanisms involved in NLRP3‐induced fibrosis are unclear. Our aim was to test the hypothesis that the NLRP3 inflammasome in hepatic stellate cells (HSCs) can directly regulate their activation and contribute to LF.
