Randomized Controlled Trial Comparative Study Clinical Trial
[Propofol for induction and maintenance of anesthesia during heart surgery. Results of pharmacological studies in man].
Numerous reports have concluded that propofol is suitable for maintenance of anesthesia by continuous infusion. The aim of this study was to evaluate the use of propofol and fentanyl for coronary bypass surgery in patients with good left ventricular function. The effects of this anesthetic combination on quality of anesthesia, hemodynamic status, and endocrine and metabolic responses were assessed. ⋯ CONCLUSION. In summary, it can be concluded that a propofol infusion technique positively enhances the recovery period after cardiac surgery and provides good control during anesthesia. However, the use of propofolfentanyl for induction of anesthesia in patients with limited coronary perfusion is not recommended because of its hypotensive effect.

The impact of diabetes on the outcomes of surgical and nonsurgical treatment of patients in the spine patient outcomes research trial.
A secondary analysis comparing diabetic patients with nondiabetic patients enrolled in the Spine Patient Outcomes Research Trial (SPORT). ⋯ Diabetic patients with SpS and DS benefited from surgery, though older SpS patients with diabetes have more postoperative complications. IDH patients with diabetes did not benefit from surgical intervention.

Randomized Controlled Trial Clinical TrialUsing attentional bias modification as a cognitive vaccine against depression.
Negative attentional biases are thought to increase the risk of recurrence in depression, suggesting that reduction of such biases may be a plausible strategy in the secondary prevention of the illness. However, no previous study has tested whether reducing negative attentional bias causally affects risk factors for depressive recurrence. The current experimental medicine study reports the effects of a computerized attentional bias modification (ABM) procedure on intermediate measures of the risk of depressive recurrence (residual depressive symptoms and the cortisol awakening response) in patients with recurrent depression. ⋯ Positive face-based ABM was able to reduce intermediate measures of recurrence risk in previously depressed patients. These results suggest that ABM may provide a "cognitive vaccine" against depression and offer a useful strategy in the secondary prevention of the illness.

Randomized Controlled Trial Multicenter Study Comparative StudyImpact of coronary anatomy and stenting technique on long-term outcome after drug-eluting stent implantation for unprotected left main coronary artery disease.
This study sought to evaluate the impact of anatomic and procedural variables on the outcome of the unprotected left main coronary artery (uLMCA) itself after drug-eluting stent (DES) implantation. ⋯ PCI of uLMCA lesions with DES is safe and effective out to 3 years. TBL and multiple stents were independent predictors for ISR. In the multivariate analysis, independent predictors for TLR were TBL, age, and EuroSCORE (European System for Cardiac Operative Risk Evaluation). (Drug-Eluting-Stents for Unprotected Left Main Stem Disease [ISAR-LEFT-MAIN]; NCT00133237).

Randomized Controlled Trial Comparative StudyThe different effects of midazolam and propofol sedation on dynamic cerebral autoregulation.
Although midazolam and propofol reduce cerebral blood flow (CBF) similarly, they generate different effects on the autonomic nervous system and endothelium-induced relaxation. Midazolam induces sympathetic dominance, whereas propofol induces parasympathetic dominance. Midazolam has no effect on endothelium-dependent relaxation, whereas propofol suppresses endothelium-dependent relaxation. Moreover, midazolam apparently constricts cerebral arterioles. We therefore hypothesized that midazolam and propofol have different effects on dynamic cerebral autoregulation. ⋯ Our results suggest that midazolam and propofol sedation have different effects on dynamic cerebral autoregulation despite causing equivalent decreases in steady-state CBF velocity. Only midazolam sedation is likely to improve dynamic cerebral autoregulation.
