Active clinical trials for "Cerebral Infarction"

This study has been added as a sub study to the Simulation Training for Emergency Department Imaging 2 study (ClinicalTrials.gov ID NCT05427838). The purpose of the study is to assess the impact of an Artificial Intelligence (AI) tool called qER 2.0 EU on the performance of readers, including general radiologists, emergency medicine clinicians, and radiographers, in interpreting non-contrast CT head scans. The study aims to evaluate the changes in accuracy, review time, and diagnostic confidence when using the AI tool. It also seeks to provide evidence on the diagnostic performance of the AI tool and its potential to improve efficiency and patient care in the context of the National Health Service (NHS). The study will use a dataset of 150 CT head scans, including both control cases and abnormal cases with specific abnormalities. The results of this study will inform larger follow-up studies in real-life Emergency Department (ED) settings.

This study is a multi-center, prospective, registry study. This research was supported by the National Key Research and Development Program. To establish a domestic multi-center, large-scale "brain-heart comorbidity" dynamic database platform including clinical, sample database, image and other multi-dimensional information requirements, through the construction of a multi-center intelligent scientific research integration platform based on artificial intelligence. Any of newly diagnosed cardiovascular related diseases were identified via ICD-10-CM codes: I21, I22, I24 (Ischaemic heart diseases) [i.e., ACS], I46 (cardiac arrest), I48 (Atrial fibrillation/flutter), I50 (Heart failure), I71 (Aortic disease), I60 (subarachnoid hemorrhage), I61 (intracerebral hemorrhage), I63 (Cerebral infarction), I65 (Occlusion and stenosis of precerebral arteries), I66 (Occlusion and stenosis of cerebral arteries), I67.1 (cerebral aneurysm), I67.5 (moyamoya diseases), Q28.2 (Arteriovenous malformation of cerebral vessels). The data is stored on the brain-heart comorbidity warehouse via a physical server at the institution's data centre or a virtual hosted appliance. The brain-heart comorbidity platform comprises of a series of these appliances connected into a multicenter network. This network can broadcast queries to each appliance. Results are subsequently collected and aggregated. Once the data is sent to the network, it is mapped to a standard and controlled set of clinical terminologies and undergoes a data quality assessment including 'data cleaning' that rejects records which do not meet the brain-heart comorbidity quality standards. The brain-heart comorbidity warehouse performs internal and extensive data quality assessment with every refresh based on conformance, completeness, and plausibility (http://10.100.101.65:30080/login).

The study aimed to access the microvascular changes in the superficial capillary plexus (SCP) and deep capillary plexus (DCP) in patients with ischemic stroke and its different types using optical coherence tomography angiography.

Carotid Web located at the bulb level is a rare condition and is often associated with severe cerebral infarction in the carotid territory. This condition has been described predominantly in the black population. However, limited data are available for the epidemiology of carotid web and often result from selected population studies. It has been shown that the carotid web is a focal intimal dysplasia. Rate of ischemic stroke recurrence is high, even in patients treated with antiplatelet therapy. This subtle lesion is often unknown and misdiagnosed including in stroke unit. We assume that the implementation of a multicentric cohort would allow a comprehensive analysis of the carotid web condition.

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.

The purpose of this study is to observe the efficacy and safety of ozonated autohemotherapy in patients of post-ischemic stroke insomnia and to explore its mechanism of action.

The main purposes of this trial are to analyze the pharmacodynamic substances and the effects of Yiqihuayu Decotion for acute ischemic stroke. The trial is a non-randomized, controlled clinical trial.

Ischemic stroke has high morbidity and mortality worldwide. Stroke patients experience physical, psychological, and social problems, and require rehabilitation. The aim of stroke rehabilitation is to support patients in optimizing their physical, functional, mental, social, and occupational aspects. Telerehabilitation-based coaching interventions are among the individualized interventions applied to patients. This study aimed to examine the effects of telerehabilitation-based coaching interventions on self-efficacy, modifiable risk factors, and repeated hospitalizations in patients with ischemic stroke. It is predicted that discharge education in disease management and telerehabilitation-based coaching interventions will increase self-efficacy, reduce modifiable risk factors (blood pressure, cholesterol, triglyceride, HbA1c levels, body mass index, smoking, and alcohol use), and reduce repeated hospitalizations. With an education booklet prepared for ischemic stroke patients and primary care providers, one-on-one face-to-face education is planned while patients are in the clinic on the fourth or fifth day of stroke. Determination of individual goals with motivational interview, sending educational videos prepared in cooperation with the multidisciplinary health team to the phones or e-mails of the patients, providing telerehabilitation-based coaching a total of seven times for three months after discharge, monitoring the targets set weekly and monthly, and monthly follow-up after three months. It is planned to support patients with practices such as achieving their goals, maintaining healthy lifestyle changes such as diet and physical activity, and monitoring metabolic parameters. The evaluation form of the education booklet, videos prepared with the cooperation of the multidisciplinary team, and phone call evaluation form will be evaluated by 10 experts. The preliminary application will be tested with 6 patients, and the final form will be provided. The second phase of the study was designed as a single-center, single-blind (participant), randomized controlled study. The study will be carried out with a total of 60 patients with ischemic stroke, 30 in the intervention group and 30 in the control group, who continued to be followed up and treated at the Neurology Clinic of Akdeniz University Hospital.

IMMUNOSTROKE study aims to describe the immuno-inflammatory and thrombo-inflammatory profiles during the course of AIC management by reperfusion treatment and to monitor changes in these different parameters over time. Post-hoc analyses will make it possible to correlate the immuno-inflammatory and thrombo-inflammatory profiles and their evolution with the clinical outcome in terms of post-AIC functional and cognitive disability.

The main purpose of this multicentric, prospective, randomized, placebo-controlled, double-blind study is the validation of pulsed ELF-MF stimulation as non-invasive and safe tool to promote recovery in acute ischemic stroke patients. 124 patients with acute ischemic stroke will be recruited and randomly assigned to real or sham group. Patients will be stimulated with pulsed ELF-MF (75 Hz, 1,8 mT), for 120 min daily, for 5 consecutive days, starting within 48 hours from the onset of stroke. The primary outcome will consist of reduction of the expected infarct growth at MR measured in the subacute and chronic phase. Secondary outcomes will explore clinical effectiveness, safety and tolerability of pulsed ELF-MF in acute ischemic stroke.
