Filter by:Preclinical research has established a convincing connection between changes in the gut microbiota composition and stroke outcome. However clinical data on the gut-brain axis, and its chronic characteristics, is sparse. Additional investigations in the context of ischemic stroke regarding the relationship between dysbiosis and functional changes of the microbiome, as characterized by the metabolome, are still required. The StrokeMicroBiomics study will offer insight into these mechanisms and offer new potential targets for therapeutic interventions. The primary objective is the characterisation of gut dysbiosis in ischemic stroke patients in the acute phase after stroke and during a 3 month follow-up period. The secondary objectives include the identification of dysregulated gut microbiome metabolites and key immune cell populations in addition to the clinical progression of the study participants during the 3 month follow-up period after disease onset.
The purpose of this study is to establish a methodological framework based on existing advanced neuroimaging technologies as a new clinical neuroimaging tool for assessment of possible affected brain connections in stroke and TIA patients. Thus, providing new insights into microstructural changes that may underline why those patients experience deficits like fatigue.
Patient Registration Study of Acute Ischemic Stroke/transient ischemic attack(TIA) With Atrial Fibrillation (AISWAF) is a single-center prospective, consecutively, observational study, was conducted in patients with acute ischemic stroke/TIA with atrial fibrillation. The aim of this study was to understand the stroke mechanism, the regularity of stroke recurrence and its influencing factors, to establish a risk stratification model for stroke recurrence, and to preliminarily explore the relationship between stroke mechanism, risk stratification and antithrombotic regimen in this population.
Transient ischemic attack (TIA) is a common neurologic emergency. Although the detection of atrial fibrillation (AF) has identical consequences for preventive therapy in patients with ischemic stroke and TIA, the management setting and diagnostic pathways frequently differ substantially between both manifestations. Despite these differences between stroke and TIA patients, previous studies have investigated diagnostic work-up for AF primarily in stroke patients. Thus, there is no common practice or "gold standard" of rhythm monitoring for TIA patients in most healthcare systems and the optimal method and duration of cardiac monitoring for TIA patients is currently unknown. This is likely to result in a substantial under-diagnosis of AF in TIA patients, failure to initiate appropriate secondary preventive medication (i.e. anticoagulation) and ultimately the occurrence of many otherwise preventable strokes. The primary research question of the trial is whether prolonged ECG recording (intervention) significantly increases the rate of detection of paroxysmal AF compared to 24 h electrocardiogram (ECG) monitoring (control) 6 months after start of monitoring in patients with recent TIA. The co-primary question of the trial is whether 28 d non-invasive continuous ECG monitoring is non-inferior to ECG recording using an implanted event recorder for AF detection.
The purpose of this study is to assess the safety and efficacy of glucagon-like peptide-1 (GLP-1) analogue liraglutide in the treatment of acute minor stroke (National Institute of Health stroke scale, NIHSS ≤ 3) or high-risk transient ischemic attack (TIA) (ABCD2 score ≥ 4 ) patients with type 2 diabetes mellitus.
The aim of the study is to find a radiological biomarker of Transient Ischemic Attacks (TIA) thanks to functional Magnetic Resonance Imaging (fMRI) done within the 24 hour after symptoms onset.
The proposed study will investigate the clinical use of the ISCDX test that may differentiate between diverse stroke etiologies as listed below: Aim 1: Differentiate between cardioembolic and large artery atherosclerotic ischemic strokes, when hemorrhagic stroke is ruled out, as defined by TOAST classification of subtypes of acute ischemic stroke. Aim 2: In cases of ischemic strokes of unknown or "cryptogenic" etiology, determine the ability of biomarker blood tests to predict etiology between cardioembolic and large artery atherosclerotic.
The CARDIOSTROKE is a randomized trial comparing mobile-device assisted control of hypertension together with screening of occult atrial fibrillation to standard care in patients with recent ischemic stroke or transient ischemic attack.
Study is designed for two parts, a perspective, multi-center, historial control study and a randomized controlled study of acute ischemic stroke patients. For achieving the target of diagnosis and treatment KPI (Key performance indicator) of AIS patients and improving the defects of the traditional working mode, our center developed the medical records data acquisition and KPI statistics system based on computer scan. This method guarantees the authenticity of the data, It computes the KPI of the corresponding medical institutions in the corresponding period and gives feedback on a regular basis. Based on the KPI feedback system, a multifaceted quality improvement intervention is conducted in the intervention group hospitals. This study aims to explore whether this new working mode can continuously improve the overall KPI in Zhejiang province, and thus reflect the improvement of quality and standardization of medical service in AIS patients.
Fragile brain is the most common phenomenon seen in the patients undergoing CEA. The patients with fragile brain have a high incidence of postoperative brain dysfunction. This study intends to apply EEG monitoring (Sedline) to CEA to investigate whether EEG monitoring can reduce the incidence of postoperative neurological complications in CEA patients and improve their prognosis. 220 patients with CEA were randomly divided into 2 groups. Group S [Sedline monitoring + Transcranial Doppler (TCD) + regional cerebral oxygen saturation (rS02)，n=110] and group C [Bispectral index (BIS)/Sedline monitoring + TCD +rSO2,n=110], recording intraoperative and postoperative conditions, neuropsychology scale assessment, blood examination and imaging examination. The incidence of postoperative neurological complications was compared between the two groups.
