Comparative StudyPredicting risk for portal vein thrombosis in acute pancreatitis patients: A comparison of radical basis function artificial neural network and logistic regression models.
To construct a radical basis function (RBF) artificial neural networks (ANNs) model to predict the incidence of acute pancreatitis (AP)-induced portal vein thrombosis. ⋯ The RBF ANNs model is more likely to predict the occurrence of PVT induced by AP than logistic regression model. D-dimer, AMY, Hct and PT were important prediction factors of approval for AP-induced PVT.

Predicting the incidence of portosplenomesenteric vein thrombosis in patients with acute pancreatitis using classification and regression tree algorithm.
The accurate prediction of portosplenomesenteric vein thrombosis (PVT) in patients with acute pancreatitis(AP) is very important but may also be difficult because of our insufficient understanding of the characteristics of AP-induced PVT. The purpose of this study is to design a decision tree model that provides critical factors associated with PVT using an approach that makes use of classification and regression tree (CART) algorithm. ⋯ The CART model based on serum amylase, d-dimer, Acute Physiology and Chronic Health Evaluation II, and prothrombin time is more likely to predict the occurrence of PVT induced by AP.

Selective digestive decontamination in critically ill children: A survey of Canadian providers.
Selective digestive decontamination of the digestive tract involves the routine administration of oral, gastric, and intravenous antibiotics to mechanically ventilated children to prevent hospital-acquired infections. It has a strong evidence base in adults, with limited pediatric evidence. Current utilization of this intervention among pediatric physicians in North America is unknown. ⋯ Among surveyed providers, there is little knowledge and no use of selective digestive decontamination for the prevention of hospital-acquired infections. Before interventional studies are performed in pediatric practice, there is a need for study of facilitators, barriers and acceptability of SDD in practice.
