Bioinformatic analysis and clinical diagnostic value of hsa_circ_0004099 in acute ischemic stroke
This study investigates the expression and effect of hsa_circ_0004099 in acute ischemic stroke (AIS). We conducted a case-controlled study that included 40 patients with AIS within 24 hours and 40 healthy subjects during the same period as a control group. Differentially expressed circular RNAs (c ircRNAs) were obtained using GEO2R, and the expression of hsa_circ_0004099 was verified using RT-PCR. Correlation analysis of the National Institutes of Health Stroke Scale (NIHSS) disease severity score and ischemic time with hsa_circ_0004099 expression levels was also performed. The receiver opera ting characteristic (ROC) curv...

Blood pressure variability and early neurological deterioration according to the chronic kidney disease risk categories in minor ischemic stroke patients
by Jae-Chan Ryu, Jae-Han Bae, Sang Hee Ha, Jun Young Chang, Dong-Wha Kang, Sun U. Kwon, Jong S. Kim, Chung Hee Baek, Bum Joon Kim ObjectiveChronic kidney disease (CKD) increases blood pressure variability (BPV) and affects stroke outcomes. However, the effect of BPV on early neurological deterioration (END) may be different according to the renal function. MethodsWe enrolled ischemic stroke patients with a National Institutes of Health Stroke Scale of ≤5. END was defined as worsening of ≥1 point in motor power or ≥2 points in total score. BPV was calculated with BP measured during the first 5 days and presented as st...

Risk of Subsequent Events in Patients With Minor Ischemic Stroke or High-Risk Transient Ischemic Attack
This study aimed to present the prognosis after minor acute ischemic stroke (AIS) or transient ischemic attack (TIA), using a definition of subsequent stroke in accordance with recent clinical trials. In total, 9,506 patients with minor AIS (National Institutes of Health Stroke Scale ≤ 5) or high-risk TIA (acute lesions or ≥ 50% cerebral artery steno-occlusion) admitted between November 2010 and October 2013 were included. The primary outcome was the composite of stroke (progression of initial event or a subsequent event) and all-cause mortality. The cumulative incidence of stroke or death was 11.2% at 1 month, 13.3% a...

Clinical-CT mismatch defined NIHSS ≥ 8 and CT-ASPECTS ≥ 9 as a reliable marker of candidacy for intravenous thrombolytic therapy in acute ischemic stroke
by Hung-Ming Wu, I-Hui Lee, Chao-Bao Luo, Chih-Ping Chung, Yung-Yang Lin BackgroundClinical-diffusion mismatch between stroke severity and diffusion-weighted imaging lesion volume seems to identify stroke patients with penumbra. However, urgent magnetic resonance imaging is sometimes inaccessible or contraindicated. Thus, we hypothesized that using brain computed tomography (CT) to determine a baseline “clinical-CT mismatch” may also predict the responses to thrombolytic therapy. MethodsBrain CT lesions were measured using the Alberta Stroke Program Early CT Score (ASPECTS). A total of 104 patients were included: 79 pa...

A high neutrophil-to-lymphocyte ratio predicts hemorrhagic transformation of large atherosclerotic infarction in patients with acute ischemic stroke.
Abstract Increasing evidence suggests that inflammation is associated with the development of acute ischemic stroke (AIS). The neutrophil-to-lymphocyte ratio (N/L) is an important marker of inflammation and is highly correlated with mortality in stroke patients in recent studies. The N/L of patients who experience hemorrhagic transformation (HT) after AIS is know, but any relationship between N/L and large artery atherosclerosis (LAA) remains unclear, this is our present topic. We enrolled 185 patients with LAA-type HT in the development cohort from a prospective, consecutive, hospital-based stroke registry to thi...

Clinical effect of mechanical fragmentation combined with recombinant tissue plasminogen activator artery thrombolysis on acute cerebral infarction.
This study aims to explore the clinical effect of mechanical fragmentation combined with recombinant tissue plasminogen activator (rt-PA) artery thrombolysis on acute cerebral infarction (ACI). One hundred and thirty-two cases of ACI patients were randomly divided into an experimental group (66 patients) and a control group (66 patients). The experimental group was treated with mechanical fragmentation combined with rt-PA artery thrombolysis method, while the control group was treated with only the rt- PA artery thrombolysis method. All the patients had their basic information recorded. A computational analysis on National...

The Number of Stenotic Intracranial Arteries Is Independently Associated with Ischemic Stroke Severity
by Xiaodan Wei, Zhuang Liu, Min Li, Chunhua Yang, Wenming Wang, Xianglin Li, Shuping Zhang, Xuri Li, Geng Tian, Jonas Bergquist, Bin Wang, Jia Mi BackgroundThe severity of ischemic stroke symptoms varies among patients and is a critical determinant of patient outcome. To date, the association between the number of stenotic intracranial arteries and stroke severity remains unclear. AimsWe aimed to investigate the association between the number of stenotic major intracranial arteries (NSMIA) and ischemic stroke severity, as well as the degree of stenosis and common stroke risk factors. MethodsWe performed a retrospective ana...

Interleukin-6 Receptor Polymorphisms Contribute to the Neurological Status of Korean Patients with Ischemic Stroke.
Authors: Kim DH, Yoo SD, Chon J, Yun DH, Kim HS, Park HJ, Kim SK, Chung JH, Kang JK, Lee SA Abstract To investigate the contribution of the interleukin-6 receptor (IL-6R) gene single nucleotide polymorphisms (SNPs) to the neurological status of Korean patients with ischemic stroke (IS), two SNPs of the IL-6R gene (rs4845617, 5 UTR; rs2228144, Ala31Ala) were selected. IS patients were classified into clinical phenotypes according to two well-defined scores: the National Institutes of Health Stroke Survey (NIHSS) and the Modified Barthel Index scores. There were 121 IS patients and 291 control subjects. The SNP rs484...

Association between Carotid Artery Stenosis and Cognitive Impairment in Stroke Patients: A Cross-Sectional Study
by Wei Yue, Anxin Wang, Runxiu Zhu, Zhongrui Yan, Shouhuan Zheng, Jingwei Wang, Jia Huo, Yunlin Liu, Xin Li, Yong Ji To investigate potential associations between carotid artery stenosis and cognitive impairment among patients with acute ischemic stroke and to provide important clinical implications. We measured the degree of carotid artery stenosis and recorded the Mini-Mental State Examination score (MMSE) at admission in 3116 acute ischemic stroke patients. The association between carotid stenosis and cognitive impairment assessed by MMSE was tested using multivariate regression analysis. Other clinical variables of in...
