This study was undertaken to identify the risk of bleeding events and potential risk factors within 90 days in patients who carried CYP2C19 loss-of-function alleles and received dual antiplatelet therapy after minor stroke or transient ischemic attack.A total of 6,412 patients were enrolled from the CHANCE-2 (Clopidogrel with Aspirin in High-Risk Patients with Acute Non-disabling Cerebrovascular Events II) trial. The main outcome was any bleeding within 90 days defined by the criteria from GUSTO (Global Utilization of Streptokinase and Tissue Plasminogen Activator for Occluded Coronary Arteries).A total of 250 (3.9%) bleeding events were reported, which occurred mainly within the 21 days of dual antiplatelet therapy (200 cases, 3.1%). Minor bleeding of the skin bruises, epistaxis, and gum bleeding were most frequent. Multivariate analysis showed that treatment with ticagrelor-aspirin compared with clopidogrel-aspirin was associated with increased bleeding (hazard ratio [HR] = 2.21, 95% confidence interval [CI] = 1.68-2.89, p 0.001). Current smoking was associated with a lower risk of bleeding (HR = 0.70, 95% CI = 0.52-0.95, p = 0.02). Additionally, ticagrelor-aspirin compared with clopidogrel-aspirin was associated with higher risk of bleeding in patients aged65 years (HR = 2.87, 95% CI = 1.95-4.22) and those without diabetes mellitus (HR = 2.65, 95% CI = 1.88-3.73; p for interaction = 0.04 and 0.03, respectively).Bleeding events mostly occurred within the 21-day dual antiplatelet therapy stage and were generally mild. The risk of bleeding was greater in nonsmoking patients, and was associated with treatment with ticagrelor-aspirin compared with clopidogrel-aspirin, particularly in patients aged65 years and nondiabetic patients.

Epilepsy is a brain and neurological disorder with high prevalence. It was reported that more than 70% of epileptic seizures were controlled by anti-epileptic medications, whereas the lack of evidence with respect to head-to-head comparisons motivated researchers to seek alternative approaches that are able to provide deep insights into the profile of anti-epileptic medications. In this study, we performed a network meta-analysis (NMA) to evaluate the efficacy and safety of anti-epileptic medications for partial seizures of epilepsy. Publications were retrieved from PubMed, Embase, and Cochrane Library. Then, studies were screened and selected based on the inclusion criteria. Data were extracted and a NMA was performed to combine both direct and indirect evidence. Surface under the cumulative ranking curve (SUCRA) was obtained for ranking purposes. Consistency between direct and indirect evidence was assessed by using the node-splitting method. Seventeen anti-epileptic medications from 90 publications were enrolled. Fifty percent responder and state of seizure freedom were studied as outcomes for efficacy; treatment emergent adverse effect (TEAE), including dizziness, somnolence, headache, fatigue, and nausea were evaluated as safety outcomes. Topiramate, levetiracetam, pregabalin, and oxcarbazepine were recommended for their relatively high efficacy and low-risk of adverse events for partial seizures. Rufinamide was the least preferable medication due to its low efficacy and high-risk of adverse effects. J. Cell. Biochem. 118: 2850-2864, 2017. © 2017 Wiley Periodicals, Inc.
