Pancreatic cyst fluid concentration of high-mobility group A2 protein acts as a differential biomarker of dysplasia in intraductal papillary mucinous neoplasm.
No reliable cyst fluid biomarkers exist that allow preoperative identification of patients with intraductal papillary mucinous neoplasms (IPMNs) and high-risk pathology. High-mobility group (HMG) A2 protein has been demonstrated to be a biomarker of dysplasia in IPMNs. It is unknown whether HMGA2 protein is present in the cyst fluid from IPMNs. The aims of this study were to determine whether HMGA2 protein is present in the cyst fluid of IPMNs and demonstrate whether HMGA2 protein concentration correlates with the degree of dysplasia. ⋯ HMGA2 protein is present in IPMN cyst fluid. Significantly higher concentrations of cyst fluid HMGA2 protein are found in IPMNs with HGD compared with lesions with LGD or MD. Cyst fluid concentrations of HMGA2 protein may thus serve as a biomarker to differentiate patients with high-risk IPMNs from those with low-risk IPMNs.

Comparative StudyRisk stratification in acute upper GI bleeding: comparison of the AIMS65 score to the Glasgow-Blatchford and Rockall scoring systems.
The American College of Gastroenterology recommends early risk stratification in patients presenting with upper GI bleeding (UGIB). The AIMS65 score is a risk stratification score previously validated to predict inpatient mortality. The aim of this study was to validate the AIMS65 score as a predictor of inpatient mortality in patients with acute UGIB and to compare it with established pre- and postendoscopy risk scores. ⋯ The AIMS65 score is a simple risk stratification score for UGIB with accuracy superior to that of GBS and pre-endoscopy Rockall scores in predicting in-hospital mortality and the need for ICU admission.
