Randomized Controlled TrialThe degree of oxidative stress is associated with major adverse effects after lung resection: a prospective study.
This prospective randomized study was conducted in order to define the contribution of the generated oxygen and nitrogen reactive species on postlobectomy morbidity and mortality. ⋯ Protracted (>1h) OLV should be considered a potential cause for cardiovascular complications through the generation of severe oxidative stress due to lung reexpansion.

Randomized Controlled Trial Comparative StudyEvaluation of respiratory muscle strength by randomized controlled trial comparing thoracoscopy, transaxillary thoracotomy, and posterolateral thoracotomy for lung biopsy.
The aim of this study was to demonstrate that the postoperative recovery of respiratory muscle strength is better in patients who undergo video-thoracoscopy than in patients who undergo transaxillary thoracotomy or posterolateral thoracotomy. ⋯ Video-thoracoscopy allows better recovery of respiratory muscle function after surgery than posterolateral thoracotomy. However, at 4 and 30 days after surgery, video-thoracoscopy and transaxillary thoracotomy gave similar results of impairment of respiratory muscle strength.

Randomized Controlled Trial Comparative StudyEndothelial apoptosis and circulating endothelial cells after bypass grafting with and without cardiopulmonary bypass.
We compared profiles of the numbers of circulating endothelial cells (CEC) and the apoptosis-inducing capacity of serum samples on human endothelial cells (hEC) in on-pump and off-pump coronary artery bypass grafting (CABG) patients. ⋯ The number of circulating endothelial cells and apoptotic endothelial cell death are markers of endothelial activation and damage during CABG. This study provides evidence that CABG with the use of CPB in comparison to OPCAB surgery is associated with a significantly more pronounced endothelial response in the immediate postoperative period.

Frequency, characteristics, and predictors of microbiologically documented nosocomial infections after cardiac surgery.
Nosocomial infections still remain a serious problem in patients undergoing open heart surgery. The objective of this study was to evaluate frequency, characteristics, and predictors of nosocomial infections after cardiac surgery. ⋯ Postoperative nosocomial infections are a considerable problem in cardiac surgery patients. The identified independent predictors of nosocomial infection may be useful in identifying those at high risk for development of such infection in cardiac surgery patients.

The present study was aimed to assess the results of newly developed aortic valve repair technique. ⋯ The results showed this technique to be safe and effective. Thus far broad application of this repair technique has been demonstrated to be highly feasible.
