Quantification of alcohol intake in patients with steatotic liver disease and excessive alcohol intake.

Background & Aims: Quantifying alcohol intake is crucial for subclassifying participants with steatotic liver disease (SLD) and interpreting clinical trials of alcohol-related liver disease (ALD) and metabolic and alcohol-related liver disease (MetALD). However, the accuracy of self-reported alcohol intake is considered imprecise. We compared the diagnostic and prognostic utility of self-reported alcohol intake with blood-based biomarkers of alcohol intake: phosphatidylethanol (PEth) and carbohydrate-deficient transferrin (CDT).

Accuracy and clinical outcomes of pancreatic EUS-guided fine-needle biopsy in a consecutive series of 852 specimens.

Background And Objectives: Pancreatic EUS-guided fine needle biopsy (EUS-FNB) is increasingly used. Accuracy of EUS-FNB, particularly for benign diseases, utility of additional EUS-FNB if malignancy is suspected but initial diagnosis is inconclusive, and complication rate are not fully elucidated. We evaluated operating characteristics of EUS-FNB overall and for different diagnostic categories, value of additional EUS-FNB if malignancy is suspected but initial diagnosis is inconclusive, and frequency and type of complications.

Utility of pVHL, maspin, IMP3, S100P and Ki67 in the distinction of autoimmune pancreatitis from pancreatic ductal adenocarcinoma.

Morphology plays an important role in the distinction of autoimmune pancreatitis (AIP) from pancreatic ductal adenocarcinoma (PDAC). However, we aimed to determine the utility of immunohistochemical tumor markers to contribute in the distinction of these entities. In surgical specimens with AIP (n = 20), PDAC (n = 20) and normal pancreas (n = 20), the expression of pVHL, maspin, IMP3, S100P and Ki67 was examined.
