Safety and efficacy of new oral anticoagulants compared to those of warfarin in AF patients with cancer: a meta-analysis of randomized clinical trials and observational studies.

Background: Data on the efficacy and safety of nonvitamin K antagonist oral anticoagulants (NOACs) in atrial fibrillation (AF) patients with cancer are limited. Therefore, we conducted a meta-analysis to compare the efficacy and safety between NOACs and warfarin in this population.

Methods: A comprehensive search of the PubMed, Embase, and Cochrane databases for articles published through July 2020 was performed.

Risk of bleeding complications after preoperative antiplatelet withdrawal versus continuing antiplatelet drugs during transurethral resection of the prostate and prostate puncture biopsy: a systematic review and meta-analysis.

Objective: To systematically evaluate the risk of antiplatelet drugs (APs) on bleeding complications in urological surgery.

Methods: Studies were sought and included in this review if they were clinical controlled trials and involved transurethral resection of the prostate (TURP) and prostate puncture biopsy (PPB), which compared preoperative AP withdrawal (control group) with continuing APs (experimental group) and revealed bleeding complications as outcomes. A literature search was conducted of the electronic databases PubMed, Ovid, ScienceDirect and Embase for studies published between 1990 and 2012.
