Detecting CYP2C19 genes through an integrated CRISPR/Cas13a-assisted system.

CYP2C19 gene single nucleotide polymorphisms (SNPs) should be considered in the clinical use of clopidogrel as they have important guiding value for predicting the risk of bleeding and thrombosis after clopidogrel treatment. The CRISPR/Cas system is increasingly used for SNP detection owing to its single-nucleotide mismatch specificity. Simultaneous detection of multiple SNPs for rapid identification of the CYP2C19 genotype is important, but there is no method to detect a wide variety of CYP2C19 SNPs.

Hypercoagulable states in young adults with ischemic stroke in a Stroke Belt state: a retrospective study.

We theorize that the southeastern United States has a higher stroke mortality rate and higher recurrent ischemic stroke rate than the rest of the United States due to (1) an increased prevalence of hypercoagulable states among young adults in the region, (2) failure to diagnose hypercoagulable states as the cause of ischemic stroke in young adults, and (3) underutilization of anticoagulation for ischemic stroke secondary prevention in young adults with hypercoagulable states. In an attempt to investigate this hypothesis, we conducted a retrospective chart review of 311 inpatients with first-ever ischemic stroke from age 18 to 55 years at an Oklahoma academic medical center from 1 July 2011 to 30 April 2017. Using Chi-squared test, we compared the stroke etiologic diagnosis of the attending neurologist at discharge-when hypercoagulable profile results were rarely available-to the diagnosis of a vascular neurologist postdischarge who had access to all available etiologic test results.
