Objectives: To evaluate the ability of sphericity in glioblastomas (GBMs) for predicting overall survival (OS) and the survival benefit from gross tumour resection (GTR).
Methods: Preoperative MRI scans were retrospectively analysed in IDH-wildtype GBM patients from two datasets. After MRI preprocessing and tumour segmentation, tumour sphericity was calculated based on the tumour core region.
Purpose: There has been much controversy over the use of angiotensin-converting enzyme inhibitors/angiotensin receptor blockers (ACEIs/ARBs) on patients with renal dysfunction. The purpose of this study was to summarize the evidence regarding the effect of ACEIs/ARBs administration on mortality in patients with nondialysis-dependent chronic kidney disease (CKD) by using a meta-analytic approach.
Methods: We searched the PubMed, Embase, and Web of Science databases for studies on the effect of ACEIs/ARBs administration on mortality in patients with nondialysis-dependent CKD published before March 2015.
