Multicenter Study
Hemoglobin and renal replacement therapy after cardiopulmonary bypass surgery: a predictive score from the Cardiac Surgery Registry of Puglia.
Acute Kidney Injury (AKI) after cardiac surgery is a complication influencing postoperative outcome. Preoperative hemoglobin is a predictor of postoperative AKI. We aimed to identify preoperative predictors of Renal Replacement Therapy (RRT) and to develop a new risk-scoring system including hemoglobin to better stratify the risk of events. ⋯ Our simple bedside prognostic score demonstrates good performance in predicting RRT. Hemoglobin plays an important role and future studies will clarify if preoperative anemia correction will lead to decreased RRT risk.

Multicenter Study Comparative Study
Long-term comparison of cryoballoon and radiofrequency ablation of paroxysmal atrial fibrillation: a propensity score matched analysis.
Although radiofrequency (RF) and cryoballoon (CB) based technologies for pulmonary vein isolation (PVI) have both individually been demonstrated to be effective and safe for the treatment of paroxysmal AF, head-to-head comparisons are lacking. The purpose of this study was to compare the outcome of cryoballoon versus radiofrequency ablation in patients with paroxysmal atrial fibrillation undergoing pulmonary vein isolation. ⋯ A propensity score matched comparison between CB-PVI and RF-PVI using a 3D-mapping system for AF ablation showed similar long-term success rates.

Despite the fact that recent evidence from meta-analysis of randomized trials indicates an increase in mortality, perioperative treatment with β-blockers is still widely advocated. We therefore performed a meta-analysis of cohort studies to evaluate the effects of perioperative β-blockers on mortality in patients undergoing non-cardiac surgery in the real world scenarios. ⋯ In the real world scenarios, for patients undergoing non-cardiac surgery, the routine use of β-blockers does not seem to reduce the risk of death. Moreover, those who are taking β-blockers on the day of surgery may have an increased risk of postoperative mortality. However, these results should be interpreted with caution because of the significant heterogeneity across the studies.
