Global Blood-Brain Barrier Disruption and Post-Stroke Cognitive Decline
Ischemic StrokeThe goal of this study is to gain a better understanding of why some individuals who have suffered a stroke experience post-stroke cognitive decline. Specifically this study is testing whether global disruption of the blood-brain barrier detected at the time of the stroke is informative about the risk of post-stroke cognitive decline over the next 3 years.
Prognostic Markers of Post-Stroke Depression (PROMoSD)
Acute Ischemic StrokeSingle-center prospective observational study investigating the association of brainstem raphe hypoechogenicity detected by transcranial sonography and post-stroke depression three months after an acute ischemic stroke.
a Cohort Study of Ischemic Cerebrovascular Disease
Ischaemic StrokeThis study aims to establish a multicenter, large-scale, prospective cohort of patients with ischemic stroke. Various biological samples such as blood, feces, and urine are collected to identify biomarkers associated with ischemic stroke. By integrating demographic information, clinical indicators, imaging parameters, and biomarker parameters, the study aims to develop risk assessment, early warning, and prognosis prediction models. Additionally, the study aims to identify key genes and explore relevant signaling pathways related to ischemic stroke.
The Association of Gut Microbes and Their Metabolites With Post-stroke Depression
Acute Ischemic StrokeIn this study, the clinical data of patients with AIS were collected, 16s RNA was used to detect the composition and diversity of intestinal flora, and flow cytometry and mass spectrometry were used to detect intestinal flora-related metabolites in plasma,to explore the influence of gut microbiota and its metabolites on stroke prognosis.
Post-stroke Cognitive Impairment
First-ever Ischemic StrokeCognitive PerformancePresent study aims to track the post-stroke cognitive trajectories and to investigate its inter-individual variability.
Imaging the Pathogenesis of Cerebral Small Vessel Disease
Ischemic StrokeHypertension2 moreCerebral small vessel disease (CSVD) can lead to vascular cognitive impairment and dementia (VCID). The hallmark of CSVD is the appearance and progression of white matter hyperintensities (WMH) on MRI. The goal of this study it to recruit and follow individuals at risk for WMH progression and use serial MRI scanning to gain insights into the pathogenesis of CSVD.
Epicardial Adipose Tissue Volume and Attenuation in Acute Ischemic Stroke
Ischemic StrokeExcessive accumulation or abnormal distribution of adipose tissue is a recognized risk factor for ischemic stroke. However, the impact of overweight or obesity on clinical outcomes of ischemic stroke is uncertain. The proposition of obesity paradox in stroke patients makes secondary prevention ambiguous for patients with ischemic stroke and overweight or obesity. Body mass index (BMI) or abdominal visceral fat area was used to measure obesity in previous studies. Epicardial adipose tissue (EAT) is a unique visceral fat, which has higher expression of proinflammatory genes than subcutaneous fat and abdominal visceral fat. And inflammation is closely related to the prognosis of ischemic stroke. In this study, the investigators assume EAT volume or attenuation evaluated by chest computed tomography (CT) scan might affect the prognosis of patients with acute ischemic stroke (AIS). Patients with the first acute ischemic stroke will be stratified into tertile groups based on EAT volume or attenuation. The primary endpoint measure is the proportion of patients with a favorable recovery of nerve function deficiency assessed by Modified Rankin Scale (mRS≤2) at 90 days after the onset of symptoms. Secondary endpoints include the following: the percentage of functional recovery measured by the Barthel Index (BI) at day 90 after stroke onset, the propotion of clinical improvement (with an improvement of ≥ 4 points on the National Institute of Health Stroke Scale score or the resolution of the neurologic deficit) or neurological deterioration (with a decline by ≥ 4 points in the total National Institute of Health Stroke Scale score) at day 7 after stroke onset, incidence of hemorrhagic transformation and mortality within 7 days of symptom onset.
Bio-Repository of DNA in Stroke: an Epidemiological and Genetic Study
StrokeStroke2 moreThe Bio-Repository of DNA in Stroke (BRAINS) recruits all subtypes of stroke as well as controls from two different continents, Europe and Asia. Subjects recruited from the United Kingdom (UK) will include stroke patients of European ancestry as well as British South Asians. Stroke subjects from South Asia will be recruited from India and Sri Lanka. Subjects are also recruited in Qatar. South Asian cases will also have control subjects recruited.
Potential Use of a POCT for the Direct Transfer of Stroke Patients From the Ambulance to the Thrombectomy...
StrokeAcute IschemicStroke is the leading cause of long-term disability and the second most common cause of death worldwide. Currently, the protocols require the imaging techniques at the hospitals to differ ischemic strokes with large vessel occlusion (LVO) from others. In this study, a duplex POC will be used in combination with an APP to identify LVO ischemic strokes in a 800 patients'cohort with pre-hospital and in-hospital blood samples.
Exploring Accessible Beauty for Individuals With Upper Extremity Deficits
StrokeIschemic14 moreThe purpose of this study is to investigate the accessibility of beauty products for individuals with upper extremity disabilities. By examining various factors such as packaging design, product applicators, and ease of use, this research aims to identify barriers faced by individuals with upper extremity disabilities or visual deficits when using beauty products. The study seeks to provide insights and recommendations for improving the accessibility of beauty products, ultimately promoting inclusivity and enhancing the overall beauty experience for individuals with disabilities.
