A predictive Bayesian network that risk stratifies patients undergoing Barrett's surveillance for personalized risk of developing malignancy.

Background: Barrett's esophagus is strongly associated with esophageal adenocarcinoma. Considering costs and risks associated with invasive surveillance endoscopies better methods of risk stratification are required to assist decision-making and move toward more personalised tailoring of Barrett's surveillance.

Methods: A Bayesian network was created by synthesizing data from published studies analysing risk factors for developing adenocarcinoma in Barrett's oesophagus through a two-stage weighting process.

Laparoscopic bowel resection in the presence of a lumbo-peritoneal shunt: a rare case.

The presence of a cerebrospinal fluid (CSF) shunt was previously considered a contra-indication to laparoscopic surgery, however, case reports appeared that describe laparoscopic surgery proceeding with no adverse outcomes in such patients. The majority of these reports relate to laparoscopic cholecystectomy. Here we present what we believe to be only the second report of a patient undergoing laparoscopic bowel resection in the presence of a lumbo-peritoneal shunt.

Epidemiology and location of primary retrieval missions in a Scottish aeromedical service.

Introduction: Prehospital critical care teams comprising an appropriately trained physician and paramedic or nurse have been associated with improved outcomes in selected trauma patients. These teams are a scarce and expensive resource, especially when delivered by rotary air assets. The optimal tasking of prehospital critical care teams is therefore vital and remains a subject of debate.
