Corporate governance in banks: Systematic literature review and meta-analysis

This paper provides a two steps investigation of the literature on banking corporate governance. We firstly perform a systematic literature review on the academics papers focused on risk management, compensation and ownership structure of banks. Then we run a meta-analysis investigation over more than 2,500 observations to clarify the understanding of the relationship with performance and risk in banks. The sub-group analysis related with bank performance shows a clear and significant finding: Board ownership, CEO ownership and Controlling shareholder enhance the performance of banks. Conversely, State ownership is negatively associated with bank performance. Results of the whole investigation and directions for scholars are also discussed.

Prophylactic Use

Introduction:The prophylactic use of closed suction drains after retroperitoneal lymphadenectomy in the management of gynecologic tumors has been widely used to prevent collections of clots or lymph and to avoid infections and postoperative fistulas. The improvement of newer surgical techniques, the use of antibiotic prophylaxis, and the nonclosure of the peritoneum led to the need to reevaluate the use of drains. Retrospective, prospective, and randomized studies did not find differences in the postoperative morbidity between the use and nonuse of drains. Some studies even suggested worse morbidity with the use of drains.Objectives:To assess the morbidity of the use of drains compared with no drains in a systematic literature review with aggregate effect measure (meta-analysis).Materials and Methods:Between 1966 and August 2007, 3 independent reviewers analyzed all studies that assessed the use of drains or no drains through a comprehensive literature search of the MEDLINE, EMBASE, and Cochrane Central Databases. Statistical analysis was carried out through the RevMan software.Results:Of the 285 studies initially reviewed, 11 were selected. Only 4 were considered adequate for group analysis, totaling 571 patients. When assessing outcomes altogether, namely, fever morbidity, symptomatic lymphocysts, deep vein thrombosis, pelvic infection, and fistulas, the relative risk was 1.76 (95% confidence interval, 1.04-3.01) and number necessary to harm was 12.2 referring to the use of drains.Conclusions:The prophylactic use of continuous suction drains after retroperitoneal lymphadenectomy in the management of gynecologic tumors should be avoided.

Performance Results

Background: Withania somnifera has been used as an ergogenic resource in recent years. In this scenario, a systematic literature review is justified to compile the findings in the scientific literature and to evaluate the methodological quality of these investigations. Aims: Our objective with this review was to evaluate the effects of Withania somnifera supplementation on sports performance in physical exercise practitioners. Material and Methods: This systematic literature review with meta-analysis addresses the effects of Withania somnifera supplementation on sports performance. Results: Of the parameters evaluated in the articles, the maximum oxygen uptake was shown to improve significantly in the three studies in which it was evaluated. Maximum strength was not influenced by the supplementation. Conclusions: The results of the present systematic literature review showed evidence that the supplementation of Withania somnifera over 500 mg to 1,250 mg before or after exercise can improve physical performance. Keywords: Withania, Sports, Dietary Supplements, Athletic Performance.
