Can we predict a delirium after cardiac surgery? A validation study of a delirium risk checklist.

Background: Delirium is a common temporary mental disorder that often occurs in patients who undergo cardiac surgery. It is important to prevent the negative side effects of delirium by identifying high-risk patients before surgery. Koster and colleagues designed a risk model to identify patients with an increased risk of postoperative delirium after cardiac surgery.

A European Multicenter Study of 616 Patients Receiving the Freedom Solo Stentless Bioprosthesis.

Background: The purpose of this study was to evaluate the safety and performance of the Freedom Solo valve in aortic valve replacement by clinical and hemodynamic outcomes.

Methods: Six hundred sixteen patients underwent aortic valve replacement in 18 European centers; mean age was 74.5 ± 5.

Development and validation of a 'universal' HPLC method for pyrethroid quantification in long-lasting insecticidal mosquito nets for malaria control and prevention.

Objectives: To outline the development and validation of a universal method for quantifying deltamethrin, permethrin and alpha-cypermethrin levels in a variety of long-lasting insecticidal mosquito nets.

Methods: Using the HPLC conditions found in the CIPAC method for deltamethrin quantification, the method is based on a simple extraction technique for sample preparation (heating in isooctane at approximately 100 °C for 15 min). The method was validated for linearity, specificity, accuracy, precision, insecticide stability to extraction conditions and required extraction time for insecticide removal.

Prediction of delirium after cardiac surgery and the use of a risk checklist.

Background: Delirium is a temporary mental disorder, which occurs frequently among patients who undergo cardiac surgery. Delirium prediction and its associated prevention is essential. In a previous study, a risk checklist for delirium was developed.

Consequences of delirium after cardiac operations.

Background: Delirium is a transient mental syndrome characterized by disturbances in consciousness, cognition, and perception. The risk that delirium will develop is increased in patients who undergo cardiac operations, especially the elderly. Generally, delirium during hospital admission is independently associated with many negative consequences, such as higher mortality, increased length of hospital stay, nursing home placement after admission, and cognitive and functional decline.
