Filter by:Sickle cell disease (SCD) is the most common genetic disease, affecting about 25 million people worldwide. Approximately 150,000 Nigerian children are born each year with sickle cell disease (SCD), making it the country with the largest burden of SCD in the world. Recent advancements in care for children with SCA have translated into improved survival of children in both high and low-resource settings. However, more complications of SCD are seen in those who survive to adulthood. Silent cerebral infarcts (SCI) and strokes are among the most devastating complications of SCD, affecting 40% and 10% of children, respectively. The overall goal of this study is to extend the Investigator's successful capacity-building effort in the assessment of neurological morbidity in children with SCD living in northern Nigeria (Kano) to young adults with SCD living in the same region. About 50% of all adults with SCD live in Nigeria. Despite the high prevalence of SCD in Africa, the neurological morbidity is not well characterized, limiting opportunities for primary and secondary stroke prevention strategies. At least 50% of young adults with sickle cell anemia (SCA), the most severe form of the disease, will have SCIs and an estimated 10% will have strokes, based on studies in high-resource settings. In high-resource settings, screening for abnormal transcranial Doppler (TCD) velocities in children with SCA, coupled with regular blood transfusion has resulted in a 92% reduction of relative risk for strokes. Despite this effective strategy, regular blood transfusion therapy does not seem sustainable in sub-Saharan Africa due to shortages and the risk of transfusion transmissible infections. Additionally, there is a lack of evidence-based stroke prevention strategies in young adults with SCA, either in the high-income or in low-resource settings. Based on the foregoing, the Investigators propose to determine the prevalence of neurological injury (overt stroke, transient ischemic attacks, and silent cerebral infarcts) in young adults at the transition age from 16-25 years. The Investigators will also, for the first time, assess conventional risk factors of stroke in the general population to determine whether a different prevention strategy is required to reduce the incidence of neurological injury in this high-risk population.
The main aim of this project is to demonstrate an association between gut and oral microbiota and their metabolites to carotid atherosclerosis and risk of ischemic stroke. The investigators aim to show that these metabolite levels are diet-dependent (mainly egg yalk and red meat) and associated with specific types of microbiota. The investigators to assess serum microbiota metabolite levels as a predictor of stroke and plaque progression for patients with carotid atherosclerosis.
The purpose of the ANT-006 study is to evaluate the bleeding profile of abelacimab relative to rivaroxaban in patients with atrial fibrillation (AF) at moderate-to-high risk of stroke.
Upper limb impairment occurs in approximately 70 to 80 per cent of adults post stroke. These impairments will have consequences on functional performance in activities of daily living and hence quality of life. Assessment of upper limb function is a component of rehabilitation that contributes to the selection of optimal interventions according to patient individualized needs. The Arm Activity Measure (ArmA) provides a standardized assessment of upper limb passive and active perceived performance that is only available in it's English version. The aim of this study is to translate and conduct a cross-cultural adaptation of the ArmA is order to investigate its psychometric properties through a validation study among stroke patients.
Patent foramen ovale (PFO) is a prevalent cause of ischemic stroke and transient ischemic attack (TIA) in young patients. Its role as a cause of cerebrovascular events in the older population is more controversial because of other competing causes are more frequent in the elderly. Recent randomized controlled trials (RCTs) have shown that PFO closure is associated with a 59% relative risk reduction in the risk of recurrent ischemic stroke. As such, the number of PFO closure procedures are expected to increase substantially in the upcoming years. Real world data (RWD) informing on the medical management, the risk of stroke recurrence, incident atrial fibrillation, and other outcomes in stroke patients with PFO, with and without PFO closure, will become crucial for understanding how results from RCTs are translated into clinical practice globally. The IMPROVE (International Multicenter Patent foRamen OVale & strokE) Registry is an observational, multicenter, international registry of men and women with an ischemic stroke or TIA. The aim is to enroll 8,800 patient-years at ≥50 sites in ≥20 countries. The IMPROVE Registry will provide important information about the management and related outcomes of patients with ischemic stroke or TIA and PFO throughout different regions of the world and across a wide spectrum of healthcare systems.
Stroke ranks 3rd among disability-causing diseases worldwide. Following a stroke, loss of lower extremity motor function causes serious gait disturbances. The walking activity is the basis for daily and social engagement activities. Mobility (locomotion) ability; gait analysis can be evaluated with tests and reports examining walking performance. ABILOCO is also a questionnaire developed by Caty et al., evaluating mobility and locomotion in individuals after stroke. The aim of this study is; To investigate the validity and reliability of the Turkish version of the ABILOCO questionnaire developed to evaluate mobility in patients with stroke. The sample of the study will be literate individuals who have had a stroke who applied to the Neurology Unit of Ankara Hacettepe University Faculty of Physical Medicine and Rehabilitation. Demographic information of the cases will be recorded. ABILOCO questionnaire will be adapted to Turkish. The validity and reliability comparison of the ABILOCO questionnaire with the Berg Balance Scale and Timed Get Up and Go Test will be performed.
Stroke is an independent risk factor for venous thrombosis (VTE), which leads to a significant increase in the mortality and disability rate after stroke. For patients with high risk factors for VTE such as advanced age, paralysis, infection, dehydration, etc., the incidence of death and disability is higher. Studies have shown that the incidence of deep vein thrombosis in bedridden ischemic stroke patients is about 20%, and the incidence of pulmonary embolism is about 2%, and causes 10% of post-stroke deaths. In order to prevent the occurrence of VTE, the American Heart Association, the American Stroke Association, the Cerebrovascular Disease Group of the Neurology Branch of the Chinese Medical Association, etc. pointed out in the guidelines that heparin or low molecular weight heparin should be used for stroke patients with "restricted mobility" or "incapable mobility" to prevent VTE. For patients with evidence of thrombosis or symptoms of DVT, antithrombotic therapy should be initiated immediately. Paradoxically, ischemic stroke significantly increases the risk of cerebral hemorrhage. Besides There is an increased risk of primary intracerebral hemorrhage (ICH) associated with aspirin or antiplatelet agent monotherapy and it is difficult to achieve a balance between preventing blood clots and reducing the risk of bleeding complications. In addition, stroke patients are elderly and have speech and intellectual impairment, and the non-specific symptoms and signs of intracranial hemorrhage caused by improper antithrombotic therapy make the rate of misdiagnosis and missed diagnosis extremely high. Therefore, clarifying the clinical characteristics of stroke patients with VTE and launching targeted interventions to effectively balance the risk of anti-thrombosis and bleeding have become the key to improving the prognosis of patients. This study is based on real-world data to study the bleeding risk and antithrombotic treatment options in VaS (1) the risk factors associated with hemorrhage in patients with VTE after stroke; and (2) the characteristics and pharmacotherapeutics regimen of high-risk populations with VTE after stroke; and(3) the Optimal antithrombotic treatment regimen for patients with VTE after stroke, including the timing of starting and stopping the antithrombotic treatment, selection of varieties, dosage, and course of treatment, etc.
The aim of this study is to examine the effect of an additional VR training program on unilateral spatial neglect (USN) after stroke. Principally, clinical assessment of the presence of unilateral spatial neglect and additionally the severity of USN will be measured using the Behavioral Inattention test (BIT), using only the BIT Conventional subtest (BITC). Secondarily, the VR outcomes will be included as well. Finally, we want to determine if the effects last over a short period of time. It is important to know whether the potential effects of the VR-training remain without continuing the intervention. Therefore, we will perform a follow-up assessment after 1 week.
This study will test whether a culturally-tailored nutrition and exercise intervention designed for African-American women will lead to sustained improvements in exercise and healthy eating through improvements in self-management mediators: mindfulness, stress management, positive reappraisal, self-regulation, and self-efficacy.
The aim of the study is to collect and analyze specimen from ischemic stroke patients undergoing thrombectomy procedures and from patients undergoing minimally invasive surgery for intracranial hematoma evacuation.
