Recurrence of thrombotic events during aspirin therapy is known as aspirin resistance (AR). This study aimed to investigate the rate of AR, the factors influencing AR in patients with acute ischemic stroke under regular aspirin use, and the relationship between AR and ABCB1 (MDR-1) C3435T (rs1045642) polymorphism. Throughout this multicenter prospective study, 174 patients with acute ischemic stroke who had been prescribed aspirin for at least one month due to the risk of vascular disease, along with 106 healthy volunteers, were included as part of the study group.

Can C-reactive protein/albumin ratio be a prognostic factor in acute stroke patients undergoing mechanical thrombectomy?

Introduction: C-reactive protein (CRP) and albumin are markers synthesized by the liver and may reflect inflammatory responses. CRP/Albumin ratio (CAR) serves better to reflect the inflammatory state and therefore the prognosis. Worse prognosis is reported in previous studies when CAR rate on admission is high in patients with stroke, aneurysmal subarachnoid hemorrhage, malignancy or patients followed in intensive care units.

Understanding the Burden of Atrial Fibrillation and Importance of Screening: A Global Perspective and Recommendations for Turkey.

Considering the aging population, the increase in predisposing factors, and the improvement in healthcare with increased survival rates, atrial fibrillation has been the most common cardiac arrhythmia in adults with a rise in the estimated lifetime risk over recent years. While aging is a powerful risk factor for atrial fibrillation, the leading prevalent comorbidities are hypertension, heart failure, obesity, obstructive sleep apnea, diabetes mellitus, and chronic kidney disease. Atrial fibrillation is associated with substantial morbidity, impaired quality of life, and increased mortality and healthcare costs.

The Role of Non-Vitamin K Antagonist Oral Anticoagulants (NOACs) in Atrial Fibrillation: Treatment Management Based on Patient and Drug Characteristics.

Data from Turkey revealed that atrial fibrillation patient percentage under adequate anti- coagulation in Turkey is less than that in other countries due to multiple parameters such as treatment adherence problems, failure to follow guideline recommendations, negative perspective on the use of new drugs, drug costs, and payment conditions. The aim of this article is to provide physicians with a compiled resource that focuses on the differences between non-vitamin K antagonist oral anticoagulants and heterogeneity of atrial fibrilla- tion patients by reviewing the global and national data from a multidisciplinary perspective and provide guidance on the choice of non-vitamin K antagonist oral anticoagulants in atrial fibrillation patients. A gastroenterologist, 2 neurologists, and 11 cardiologists from university and training and research hospitals in Turkey who are experienced in atrial fibrillation and non-vitamin K antagonist oral anticoagulant treatments gathered in 3 separate meetings to identify the review topics and evaluate the outcomes of the systematic literature search.

Endovascular Thrombectomy With or Without Intravenous Thrombolysis: A Meta-Analysis of Randomized Controlled Trials.

Background: We performed this meta-analysis of randomized clinical trials to compare the outcomes in patients treated with endovascular thrombectomy who receive prior intravenous thrombolysis with those who do not receive such treatment. Recently, one randomized trial reported outcomes to address this issue, so timely update of meta-analysis is needed to determine the value of administering intravenous thrombolysis before endovascular thrombectomy.

Materials And Methods: Four randomized clinical trials are included in our meta-analysis.

Predictors of Symptomatic Hemorrhage After Endovascular Treatment for Anterior Circulation Occlusions: Turkish Endovascular Stroke Registry.

We evaluated the predictive factors of symptomatic intracranial hemorrhage (SICH) in endovascular treatment of stroke. We included 975 ischemic stroke patients with anterior circulation occlusion. Patients that had hemorrhage and an increase of ≥4 points in their National Institutes of Health Stroke Scale (NIHSS) after the treatment were considered as SICH.

Elevated Red Blood Cell Distribution Width May Be a Novel Independent Predictor of Poor Functional Outcome in Patients Treated with Mechanical Thrombectomy.

Purpose: Red blood cell distribution width (RDW) evaluates the variation (size heterogeneity) in red blood cells.
