Background: COVID-19 has been associated with negative results in patients with A blood group and with a better evolution in O blood group individuals.
Aim: Because the evidence regarding ABO blood groups and COVID was empirically not that clear in our country, we tested the association regarding COVID-19 and blood groups.
Material And Methods: Adult patients were enrolled in this prospective, case-control, observational multicenter study.
Background: Polymorphisms in the endothelial nitric oxide synthase (eNOS) and in the plasminogen activator inhibitor -1 (PAI-1) genes have been implicated in stroke pathogenesis but results are still controversial. The aim of this study was to examine the possible contribution of Glu298Asp in the eNOS and 4G/5G in the PAI-1polymorphisms with ischemic stroke in a young Mexican population.
Materials And Methods: In a case-control study, conducted between January 2006 and June 2010, 204 patients ≤45 years of age with ischemic stroke and 204 controls matched by age and gender, were recruited.
It has been identified that platelet glycoprotein IIIa PIA1/A2 polymorphism plays an important role in atherothrombotic disease such as myocardial infarction and stroke, but results remain controversial. Here, we investigated whether the PIA2 allele is associated with ST myocardial infarction or idiopathic ischemic stroke in young individuals in two independent studies. In a case-control study 275 patients with ST elevation myocardial infarction ≤45 years of age and 278 controls were recruited.
