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.

Early continuous renal replacement therapy in septic acute kidney injury could be defined by its initiation within 24 hours of vasopressor infusion.
The optimal timing for the initiation of early continuous renal replacement therapy (CRRT) is uncertain and requires a practically feasible definition with acceptable evidence. ⋯ Considering the possible therapeutic measurement by physician on the basis of the results in this study, early CRRT could be defined by a Tvaso-CRRT less than 24 h.

A description of the "event manager" role in resuscitations: A qualitative study of interviews and focus groups of resuscitation participants.
Communication during resuscitation is essential for the provision of coordinated, effective care. Previously, we observed 44% of resuscitation communication originated from participants other than the physician team leader; 65% of which was directed to the team, exclusive of the team leader. We called this outer-loop communication. ⋯ "Outer-loop" communication supports resuscitation activities. An event manager gives direction to the team, coordinates activities, and supports the team leader. We describe a new role in resuscitation in light of structural organizational theory and cognitive load with a view to incorporating this structure into resuscitation training.

Community analysis of dental plaque and endotracheal tube biofilms from mechanically ventilated patients.
Mechanically ventilated patients are at risk for developing ventilator-associated pneumonia, and it has been reported that dental plaque provides a reservoir of respiratory pathogens that may aspirate to the lungs and endotracheal tube (ETT) biofilms. For the first time, metataxonomics was used to simultaneously characterize the microbiome of dental plaque, ETTs, and non-directed bronchial lavages (NBLs) in mechanically ventilated patients to determine similarities in respective microbial communities and therefore likely associations. ⋯ The high similarity between the microbiomes of dental plaque, NBLs, and ETTs suggests that the oral cavity is indeed an important site involved in microbial aspiration to the lower airway and ETT. As such, maintenance of good oral hygiene is likely to be highly important in limiting aspiration of bacteria in this vulnerable patient group.

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.
