Background: Elastography is a noninvasive method to assess liver fibrosis by measuring liver stiffness. Studies have compared elas-tography to percutaneous biopsy. Laparoscopic biopsy is associated with decreased sampling error compared to percutaneous biopsy, as laparoscopic biopsies are obtained from both liver lobes and gross nodu-larity can be visualized.
Methods: Patients undergoing laparoscopic liver biopsy were enrolled. Gross liver appearance was assessed, and biopsy specimens were blindly evaluated by a pathologist. Elastography (FibroScan) was used to measure liver stiffness.
Results: 101 patients were examined. Fibrosis was related to elasticity (Spearman correlation r=0.63; P<.0001). Elasticity was strongly associated with advanced stages of fibrosis (stages 3 and 4; Spearman correlation r(2)=0.44; P<.001). Significant fibrosis was associated with an irregular liver surface, nodularity, and thickened edge (multiple regression r(2)=0.41; P<.001). Increased elasticity was associated with a fatty-appearing liver, irregular surface, firmness, and nodularity (multiple regression r(2)=0.46; P<.001). Receiver operating characteristic curve for elasticity for identifying patients with a liver fibrosis stage of at least 3 or of 4 had an area under the curve (AUC) of 0.85 or 0.86, respectively. AUC was 0.857 when gross nodularity was used as the gold standard for cirrhosis and 0.875 when nodularity/histology were used. Elasticity of at least 7 kPa, at least 9.5 kPa, and at least 11.8 kPa had the highest accuracy for identifying patients with a fibrosis stage of at least 2, at least 3, and 4, respectively. In hepatitis C patients, AUC was 0.921, 0.882, and 0.925 when histology, gross nodularity, and nodularity/histology, respectively, were used as the gold standard for cirrhosis.
Conclusion: FibroScan could be useful for detecting advanced stages of fibrosis when validated against laparoscopic liver biopsy.

The frequency of drug-induced liver injury (DILI) in clinical trials remains a challenge for drug developers despite advances in human hepatotoxicity models and improvements in reducing liver-related attrition in preclinical species. TAK-994, an oral orexin receptor 2 agonist, was withdrawn from phase II clinical trials due to the appearance of severe DILI. Here, we investigate the likely mechanism of TAK-994 DILI in hepatic cell culture systems examined cytotoxicity, mitochondrial toxicity, impact on drug transporter proteins, and covalent binding.

Unintentional weight loss in older populations is linked to greater mortality and morbidity risks. This study aims to understand the metabolic mechanisms of unintentional weight loss and their relationship with body composition changes in older adults. We investigated plasma metabolite associations with weight and body composition changes over 5 years in 1335 participants (mean age 73.

We present Enterocytozoon bieneusi infection in four patients with autoimmune diseases undergoing prolonged monoclonal antibody therapies. Two patients suffered from inflammatory bowel disease and received anti-TNF therapies, whereas two other patients suffered from systemic lupus erythematosus with renal involvement and received anti-CD20 or anti-BLyS protein therapies. Three out of four patients consulted for diarrhea with abdominal pain without intestinal inflammation or bleeding at the time of sampling.
