Imeglimin promotes glucose-stimulated insulin secretion in the pancreas in a glucose-dependent manner and inhibits gluconeogenesis in the liver. Meanwhile, imeglimin can improve mitochondrial function in hepatocytes. We used a nondiabetic metabolic dysfunction-associated steatohepatitis (MASH) model to examine the effects of imeglimin on MASH independent of its glucose-lowering action.

Recently, endoscopic ultrasound-guided tissue acquisition (EUS-TA) has been widely used to diagnose pancreatic ductal adenocarcinoma (PDAC). The histological examination of core tissues acquired using novel biopsy needles is the primary diagnostic approach for patients with PDAC. However, in patients with early-stage PDAC, such as Stages 0 and I, EUS-TA can be challenging, and its diagnostic accuracy may be limited.

Article Synopsis
  • A study investigated the impact of the rs16906115 polymorphism in the interleukin-7 gene on immune-related adverse events (irAEs) and treatment response to immune checkpoint inhibitors within a Japanese population.
  • Conducting a comparison between participants with severe irAEs and those with none, as well as hepatocellular carcinoma patients categorized by treatment response, researchers found no significant association between the polymorphism and irAEs, but identified a link to poorer treatment outcomes in responders.
  • The findings suggest that while the rs16906115 minor allele does not predict irAEs, its homozygosity may indicate a reduced likelihood of effective treatment results in this Japanese cohort.

Article Synopsis
  • The study aimed to determine if the levels of von Willebrand factor (VWF) and a protein called ADAMTS13 can predict the progression of esophagogastric varices (EGV) in patients with liver cirrhosis caused by hepatitis C after successful antiviral treatment.
  • Researchers analyzed 47 patients who achieved a sustained virologic response (SVR) after direct-acting antiviral (DAA) therapy; 18 of these patients showed signs of EGV progression post-treatment.
  • Results indicated that a higher VWF-to-ADAMTS13 ratio (greater than 2.3) was a significant risk factor for EGV progression, suggesting that this ratio can help identify patients at risk for complications

  • - The study evaluated how the COVID-19 pandemic affected the treatment of acute cholangitis due to choledocholithiasis by analyzing medical records from April 2017 to December 2022 during a declared state of emergency in Japan.
  • - Results showed an increase in the number of endoscopic retrograde cholangiopancreatography (ERCP) cases and successful stone removals after the state of emergency. Additionally, patients treated during this time tended to be in better health, while those on certain medications and with previous health issues were fewer.
  • - The findings indicated that the pandemic led to more efficient single-stage endoscopic treatments and shorter hospital stays without increasing safety risks for patients undergoing ERCP.

Article Synopsis
  • Lipopolysaccharides (LPSs) are linked to the progression of hepatocellular carcinoma (HCC), but the exact mechanisms are still unclear.
  • The study hypothesizes that epiregulin (EREG), produced in the presence of LPS by liver cells, is a key factor in HCC growth by affecting the epidermal growth factor receptor (EGFR) in tumors.
  • Experiments in a mouse model show that LPS treatment not only increases tumor size and EREG levels but also enhances blood vessel formation and expression of IL-8, indicating EREG's role in tumor growth and invasion.
