NCT ID: NCT04800809 Active, not recruiting - Stroke Clinical Trials

The Afolabi Stroke Registry for Children and Young Adults With SCD in Northern Nigeria

Start date: April 1, 2020
Study type: Observational [Patient Registry]

Sickle Cell Anemia (SCA) occurs in 300,000 newborns per year in the world, with 150,000 affected births in Nigeria, alone. With improvement in survival for children with SCA in both high- and low-resource countries, neurological morbidity is an emerging significant public health challenge, particularly in countries with a high rate of sickle cell disease (SCD). Both silent cerebral infarcts (SCI) and overt strokes result in significant neurological morbidity and premature death. Five NIH-funded randomized controlled trials (RCT) demonstrated that regular blood transfusion or hydroxyurea therapy are efficacious treatments for primary and secondary stroke prevention in children with SCA. Despite the observation that at least 99% of children with SCA in high-resource settings reach adulthood, and approximately 60% of adults will experience one or more strokes (~50% with SCI and ~10% with overt strokes) and the high disease-burden in Nigeria, the prevalence and incidence rates of new and recurrent stroke (overt and silent strokes)have not been collected systematically in children and young adults (16-25 years old) with SCA. In the last decade, there has been growing use of stroke registries in economically advanced nations, particularly for epidemiological purposes of trend analysis, clinical effectiveness, compliance to guidelines, assessment of implementation, adoption of novel techniques, and quality improvement process. For the first time in clinical centers in Nigeria, the Investigators will conduct an observational epidemiological study to document the prevalence and track the incidence of new and recurrent strokes in children and young adults with SCD. The Investigators will create a stroke registry referred to as the Afolabi Stroke Registry for Children and Young Adults with Sickle Cell Disease in Nigeria. The overall purpose of the stroke registry is to document the natural history of SCD in a low-resource setting and to improve the quality of the care of children and young adults with SCD living in Nigeria.

NCT ID: NCT04754555 Active, not recruiting - Stroke Clinical Trials

Translation and Transcultural Adaptation of the Arm Activity Measure (ArmA) and Motor Activity Log (MAL)

Start date: February 9, 2021
Study type: Observational

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.

NCT ID: NCT04728997 Active, not recruiting - Stroke Clinical Trials

Mobility Assessment in Stroke Patients

Start date: April 3, 2019
Study type: Observational

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.

NCT ID: NCT04726007 Active, not recruiting - VTE After Stroke Clinical Trials

Management of TA in VaS-Patients and HT

Start date: January 1, 2018
Study type: Observational

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.

NCT ID: NCT04664946 Active, not recruiting - Ischemic Stroke Clinical Trials

NCT ID: NCT04648449 Active, not recruiting - Stroke, Acute Clinical Trials

Artificial Intelligence (AI) Support in Stroke Calls

Start date: September 1, 2020
Study type: Observational

More than 12.000 patients suffer acute stroke in Norway every year, but less than half of them reach hospital within the current treatment window for thrombolysis. Stroke is the third-highest cause of death and the number one cause of severe disability requiring long time care at institutions. Consequently this has a high impact on society, patients and relatives, in addition to high costs related to care estimated to approximately 10 billion NOK per year. Although there are few studies on emergency medical communication centres (EMCC) in Norway, some have shown that the performance of the emergency medical communication centres can be improved. This project will seek to amend EMCC´s handling of acute stroke inquiries using artificial intelligence (AI), thus contributing to getting the patient to hospital in time for optimal treatments.
