Filter by:Evidence suggests that oxytocin has a neuroprotective role on a systemic and cellular level in the context of acute ischemic stroke (AIS). The investigators therefore hypothesize that high levels of circulating oxytocin measured within the first 72 hours after symptom onset are associated with lower mortality and favorable outcome in acute ischemic stroke.
The purpose of this cross-sectional study is to translate and cross-culturally adapt to Spanish the Motor Evaluation Scale for Upper Extremity in Stroke Patients (MESUPES) and the Stroke Upper Limb Capacity Scale (SULCS) and to assess their psychometric properties in Spanish people with chronic stroke.
Introduction Remote cerebral hemorrhage following reperfusion treatment in ischemic stroke is rare (1.3-3.7% of all treated strokes) and is associated with worse functional and vital prognosis. Multicenter observational studies suggest that amyloid angiopathy may be one of the main risk factors for remote hemorrhage. Currently, it is unknown what happens to those patients with remote hemorrhage beyond 3 months of follow-up in terms of risk/benefit balance when receiving antiplatelet or anticoagulant therapy, as well as from a cognitive point of view. Considering an analogy with amyloid angiopathy, the hypothesis is that those patients with remote hemorrhage have a higher risk of intracranial hemorrhage during follow-up when receiving stroke secondary prevention, and will also present greater cognitive deterioration during long-term follow-up. Main Objectives - To explore the frequency and risk factors for intracranial hemorrhage during follow-up of patients with remote cerebral hemorrhage. - To explore the frequency and progression of cognitive deterioration during follow-up in patients with remote cerebral hemorrhage. Methodology Observational, prospective, multicenter registry with a population-based case-control design of consecutive patients with remote hemorrhage following reperfusion therapy in acute ischemic stroke. Inclusion criteria: Diagnosis of ischemic stroke with age greater than or equal to 18 years who has remote cerebral hemorrhage after receiving reperfusion therapy in the acute phase. Exclusion criteria: Lack of basic data (age, sex, neuroimaging data) or telephone for follow-up. The cases will be those patients with remote hemorrhage. For each case included, 4 consecutive controls will be included (2 with local parenchymal hemorrhagic transformation and 2 without hemorrhagic transformation). The data will be filled out within the (Codi Ictus de CATalunya) CICAT registry form (currently mandatory in all stroke centers in Catalonia) to which additional variables will be added. Telephone follow-up will be conducted at 3, 12, and 24 months. Main study variable: - Any type of spontaneous or traumatic intracranial hemorrhage during a 24-month follow-up. - Score on the "Short Informant Questionnaire" scale (a validated 17-question questionnaire to be conducted over the phone, where a score higher than 57 points indicates cognitive impairment). Expected sample size during a 2-year recruitment period: 105-300 patients (considering the participating centers to date). Additional information. This study is endorsed by the "Pla Director de la Malaltia Vascular Cerebral" in Catalonia. Participating Centers. Participation offers have been sent to the 28 hospitals in the hospital network of Catalonia with the capacity to administer intravenous fibrinolysis. Positive responses have been received from 13 of them so far. In case the project is accepted by the (Comité Ético de Investigación Clínica) CEIC Sant Pau, the centers that have not responded will be contacted again to obtain their participation.
Hypothesis: Hyper chloremia is associated with poor outcome in Intracerebral Hemorrhage (ICT). Hyperchloremia is defined as serum chloride level of 110mmol/L or greater. This clinical study is assuming that, by increasing the ratio of Sodium-acetate to Sodium-chloride solutions in IV treatment, the incidence of Hyperchloremia can be lowered significantly. This result can be demonstrated by measuring serum chloride levels at Baseline, 24Hr, 48Hr and 72 Hours' time intervals and compare them between the three treatment and one Control arm. Intervention (drug/biologic/device/behavioral): Phase 2-dose finding Patients will be enrolled in the study and randomized into one of the four study treatment arms(target fluid administration rate 1 ml/kg/hour) initiated within 12 hours. IVF will be prepared in the main hospital pharmacy. 1. Sodium chloride (0.9%) referred as 0.9% NaCl for 72 hours post symptom onset (60-72 hourspost randomization); 2. Sodium chloride (0.9%) and sodium acetate (0.9%) mixture 3:1 ratio for 72 hours post symptom onset (60-72 hours post randomization); 3. Sodium chloride (0.9%) and sodium acetate (0.9%) mixture 2:1 ratio for 72 hours post symptom onset (60-72 hours post randomization); 4. Sodium chloride (0.9%) and sodium acetate (0.9%) mixture 1:1 ratio for 72 hours post symptom onset (60-72 hours post randomization).
Sleep difficulties are common following stroke yet effective evidence-based interventions for improving sleep in this population are lacking. A small number of studies have investigated the use of music listening as a way to improve sleep in adults with insomnia. This study aims to examine whether a mindful music-listening intervention can reduce subjective and objective insomnia symptoms and improve mood and fatigue post-stroke. Six adults with a clinical diagnosis of stroke presenting with an insomnia disorder will be recruited from stroke services within NHS Greater Glasgow and Clyde. A multiple baseline single case experimental design will be employed. Participants will be randomly allocated to a baseline phase of 7, 11 or 15 days, followed by a five-week mindful music-listening intervention incorporating sleep hygiene. Changes in subjective and objective sleep will be measured using questionnaires and actigraphy, respectively. Mood and fatigue will also be measured. The data will be analysed using visual inspection, Tau-U and multi-level modelling.
After a stroke, it is very common to lose the ability to open the affected hand. Occupational and physical rehabilitation therapy (OT and PT) combined with non-invasive brain stimulation may help a person recover hand movement. The purpose of this study is to compare 3 non-invasive brain stimulation protocols combined with therapy to see if they result in different amounts of recovery of hand movement after a stroke.
Study using ultrasound of the brain as a diagnostic tool to differentiate between ischemic stroke and hemorrhagic stroke. Correlation of brain perfusion and size of stroke in relation to systemic hemodynamic targets will be assessed on serial scans.
This clinical trial aims to determine if a new smartphone-based speech therapy is effective and feasible for patients with post-stroke dysarthria. Participants in the intervention group will use the speech therapy app for 1 hour per day, 5 days per week, over a 4-week period. The control group will receive the same duration and frequency of traditional speech therapy as the intervention group. The study will help us understand if smartphone-based speech therapy is a viable treatment option for post-stroke dysarthria patients.
A Multicenter Registry of Endovascular Treatment for Acute Ischemic Stroke.
The goal of this observational study is to learn about epilepsy after a stroke (post-stroke epilepsy). The main questions it aims to answer are: - What make some patients develop epilepsy after a stroke? - Does sleep have an impact on the development of post-stroke epilepsy? Participants will undergo: - Electroencephalography (EEG) - Magnetic resonance imaging (MRI) - Polysomnography (only patients) Blood tests will also be taken. The patient group will be compared to the healthy controls. Researchers will also look into medical records of stroke patients hospitalized at St. Olavs hospital and collect relevant information.
