Comparative StudyMetabolic syndrome exacerbates short-term postoperative cognitive dysfunction in patients undergoing cardiac surgery: results of a pilot study.
The authors tested the hypothesis that patients with metabolic syndrome are more likely to develop short-term cognitive dysfunction after cardiac surgery with cardiopulmonary bypass. ⋯ The results indicate that short-term cognitive functions were more profoundly impaired in patients with metabolic syndrome undergoing cardiac surgery with cardiopulmonary bypass compared with their healthier counterparts.

Comparative StudyClostridium difficile-associated disease acquired in the cardiothoracic intensive care unit.
To determine the prevalence, severity, and outcome associated with Clostridium difficile-associated disease (CDAD) acquired while in the cardiothoracic intensive care unit (CTICU). ⋯ C difficile-associated disease rarely is acquired in the CTICU. Approximately one third of patients may experience disease progression, and just over a quarter may die within 30 days of diagnosis. The implementation of recommended severity definitions and treatment algorithms may reduce complication rates and merits prospective evaluation.

Comparative StudyComparative feasibility of myocardial velocity and strain measurements using 2 different methods with transesophageal echocardiography during cardiac surgery.
To assess the feasibility and correlation between tissue Doppler and speckle tracking imaging when measuring myocardial velocity, strain, and strain rate with transesophageal echocardiography. ⋯ The correlation between tissue Doppler and speckle tracking with transesophageal echocardiography appears valid when predominantly confined to segments moving in a radial direction adjacent to the ultrasound transducer. Tissue Doppler echocardiography of radial cardiac motion appears to be the most feasible technique of measuring myocardial velocity, strain, and strain rate during cardiac surgery.

Comparative StudyDoes preoperative B-type natriuretic peptide better predict adverse outcome and prolonged length of stay than the standard European System for Cardiac Operative Risk Evaluation after cardiac surgery?
Although B-type natriuretic peptide (BNP) strongly predicts cardiac morbidity and mortality, the European System for Cardiac Operative Risk Evaluation (EuroSCORE) has a modest predictive value to identify a composite operative risk after cardiac surgery. The authors tested the hypothesis that a single preoperative BNP measurement would be superior to standard EuroSCORE in predicting composite adverse outcomes after cardiac surgery. ⋯ Preoperative BNP measurement is a strong, independent, and more accurate predictor of adverse outcome than EuroSCORE in patients undergoing cardiac surgery. BNP could be considered as a simple and objective tool for the detection of high-risk patients after cardiac surgery.
