Subcutaneous and submuscular anterior ulnar nerve transposition have been widely used in patients with cubital tunnel syndrome. However, the reliable evidence in favor of 1 of 2 surgical options on clinical improvement remains controversial. To maximize the value of the available literature, we performed a systematic review and meta-analysis to compare subcutaneous versus submuscular anterior ulnar nerve transposition in patients with ulnar neuropathy at the elbow. ⋯ The available evidence is not adequately powered to identify the best anterior ulnar nerve transposition technique for cubital tunnel syndrome on the basis of clinical outcomes, that is, suggests that subcutaneous and submuscular anterior transposition might be equally effective in terms of postoperative clinical improvement. However, differences in clinical outcomes metrics should be noted, and these findings largely rely on the outcomes data from observational studies that are potentially subject to a high risk of selection bias. Therefore, more high-quality and adequately powered RCTs with standardized clinical outcomes metrics are necessary for proper comparison of these techniques.

Review Meta Analysis
Rosuvastatin Treatment for Preventing Contrast-Induced Acute Kidney Injury After Cardiac Catheterization: A Meta-Analysis of Randomized Controlled Trials.
We performed a meta-analysis of randomized controlled trials (RCTs) to evaluate the protective effects of rosuvastatin on contrast-induced acute kidney injury (CI-AKI) and major adverse cardiovascular events (MACEs) in patients undergoing cardiac catherization. PubMed, MEDLINE, Web of Science, EMBASE, ClinicalTrials.gov, and the Cochrane Central RCTs were searched for RCTs from inception to May 2015, to compare rosuvastatin for preventing CI-AKI with placebo treatment in patients undergoing cardiac catherization. Five RCTs with a total of 4045 patients involving 2020 patients pretreated with rosuvastatin and 2025 control patients were identified and analyzed. ⋯ In addition, the rosuvastatin treatment showed no effect for preventing CI-AKI in patients with chronic kidney disease (CKD) undergoing elective cardiac catherization (I = 0%, OR = 0.81, 95% CI = 0.41-1.61, P = 0.55). This updated meta-analysis demonstrated that preprocedural rosuvastatin treatment could significantly reduce the incidence of CI-AKI, with a trend toward a reduced risk of MACEs in patients undergoing cardiac catheterization. However, rosuvastatin treatment did not seem to be effective for preventing CI-AKI in CKD patients undergoing elective cardiac catheterization.

To appraise the current reporting methodological quality of randomized clinical trials (RCTs) in 3 leading diabetes journals. We systematically searched the literature for RCTs in Diabetes Care, Diabetes and Diabetologia from 2011 to 2013. Characteristics were extracted based on Consolidated Standards of Reporting Trials (CONSORT) statement. ⋯ No improvements were found in these 3 years. This study shows that methodological reporting quality of RCTs in the major diabetes journals remains suboptimal. It can be further improved to meet and keep up with the standards of the CONSORT statement.

Review Meta Analysis Comparative Study
Systematic Review and Meta-Analysis of Carotid Artery Stenting Versus Endarterectomy for Carotid Stenosis: A Chronological and Worldwide Study.
There are disparities among the results of meta-analyses under different circumstances of carotid artery stenting (CAS) versus endarterectomy (CEA) for carotid stenosis. This study aimed to assess the efficacies of CAS and CEA for carotid stenosis at 5-year intervals and worldwide. Comparative studies simultaneously reporting CAS and CEA for carotid stenosis with at least 10 patients in each group were identified by searching PubMed and Embase in accordance with preferred reporting items for systematic reviews and meta-analyses guidelines, and by reviewing the reference lists of retrieved articles. ⋯ This systematic review, compared with those of other meta-analyses, included all available comparative studies and analyzed them at 5-year intervals, in different continents, and under different study designs. Current evidence suggests that the efficacy of CEA is superior to CAS for freedom from stroke/death within 30 d, especially from 2006 to 2015, in North America and Europe. Meanwhile, the superiority was also observed for restenosis at 1-year, transient ischemic attack within 30 d, and stroke/death at 4- and 10-year follow-ups.

Review Meta Analysis
A Systematic Review and Meta-Analysis of Medical Students' Perspectives on the Engagement in Research.
Engaging students in active learning lies at the center of effective higher education. In medical schools, students' engagement in learning and research has come under increasing attention. The objective of this study was to synthesize evidence on medical students' perspectives on the engagement in research. ⋯ We acknowledged the caveats and the merit of the current review. Findings showed that engagement in research resulted in favorable reactions toward research and academic learning. Future well-designed studies using standardized research tools on how to engage students in research are recommended.
