Wentao Wang, Chun Yang, Kai Zhu, Li Yang, Ying Ding, Rongkui Luo, Shuo Zhu, Caizhong Chen, Wei Sun, Mengsu Zeng, Sheng‐Xiang Rao – 4 January 2020 – Small recurrent hepatocellular carcinoma (HCC) can show atypical imaging patterns, and a specific diagnostic algorithm for HCC is lacking. This study aimed to better characterize postoperative recurrent HCCs <20 mm in size with gadoxetic acid–enhanced magnetic resonance imaging (MRI). We evaluated 373 newly developed nodules after hepatectomy in 204 HCC patients with chronic hepatitis B virus infection.

Delaney, Alexander Ploss, Robert E. Lanford, Christian Voitenleitner – 3 January 2020 – Development of curative therapies for chronic hepatitis B virus (HBV) infection will likely require new animal models. Here, we evaluate HBV infection in squirrel monkeys based on the high‐sequence homology of the HBV receptor, Na+/taurocholate co‐transporting peptide (NTCP), between humans and squirrel monkeys.

Kaori Ishiguro, Irene K. Yan, Laura Lewis‐Tuffin, Tushar Patel – 3 January 2020 – By exploiting their biological functions, the use of biological nanoparticles such as extracellular vesicles can provide an efficient and effective approach for hepatic delivery of RNA‐based therapeutics for the treatment of liver cancers such as hepatocellular cancer (HCC). Targeting liver cancer stem cells (LCSC) within HCC provide an untapped opportunity to improve outcomes by enhancing therapeutic responses.

Joan Ericka Flores, Shivakumar Chitturi, Sarah Walker – 3 January 2020 – Selective androgenic receptor modulators (SARMs) have not been approved by the U.S. Food and Drug Administration but they are heavily promoted as alternatives to androgenic anabolic steroids. We present two cases of liver injury associated with SARMs.

Parth Shah, Vinay Sundaram, Einar Björnsson – 2 January 2020 – Biologics are among the most commonly prescribed medications for several chronic inflammatory diseases. Tumor necrosis factor alpha inhibitors, more so than other agents, have been observed to cause drug‐induced liver injury. Additionally, because the approval and popularity of checkpoint inhibitors have grown, similar patterns of liver injury have been documented, with a majority of cases describing immune‐mediated hepatitis.

Ayumi Kiso, Yukiko Toba, Susumu Tsutsumi, Sayaka Deguchi, Keisuke Igai, Saki Koshino, Yasuhito Tanaka, Kazuo Takayama, Hiroyuki Mizuguchi – 2 January 2020 – Single nucleotide polymorphisms in Tolloid‐like 1 (TLL1) and the expression of TLL1 are known to be closely related to hepatocarcinogenesis after hepatitis C virus elimination or liver fibrosis in patients with nonalcoholic fatty liver disease. TLL1 is a type of matrix metalloprotease and has two isoforms in humans, with the short isoform showing higher activity.
