Meta Analysis Comparative StudyLong-term outcomes of mechanical versus biological aortic valve prosthesis: Systematic review and meta-analysis.
In recent years, the use of surgically implanted biological aortic valves has been favored over mechanical prosthesis in patients between 50 and 70 years of age. However, outcomes on long-term survival are contradictory. The objective of this study was to determine if patients with mechanical valves have worse long-term survival than patients with biological prostheses. ⋯ Compared with biological aortic valves, mechanical valves are associated with a long-term survival benefit for patients between 50 and 70 years.

Randomized Controlled Trial Multicenter Study Comparative StudyComparison of pulmonary segmentectomy and lobectomy: Safety results of a randomized trial.
No definitive comparisons of surgical morbidity between segmentectomy and lobectomy for non-small cell lung cancer have been reported. ⋯ There was no difference in almost any postoperative measure of intraoperative and postoperative complication in segmentectomy and lobectomy patients, except more air leakage was observed in the segmentectomy arm. Segmentectomy will be a standard treatment if the superior pulmonary function and noninferiority in overall survival are confirmed.
