Filter by:A problem with breathing during sleep, called obstructive sleep apnea (OSA), likely increases the risk of stroke and is common in people who have had a stroke, present in about 2/3 of stroke survivors. There is also evidence that OSA predicts worse outcome after stroke. The question being addressed in the Stroke and CPAP Outcome Study 3 (SCOUTS3) is how to improve use of continuous positive airway pressure (CPAP) therapy to treat OSA when started during intensive stroke rehabilitation.
The research will investigate the hypothesis that timely identification of the optimal value of the cerebral perfusion pressure (optCPP) or optimal arterial blood pressure (optABP) is possible after detecting informative episodes of arterial blood pressure (ABP) that reflects the physiological autoregulatory reactions of the cerebral blood flow, This biomedical study will be conducted to test this hypothesis and to develop an algorithm for identification of optimal brain perfusion pressure within limited time (several tens of minutes). The goal of this observational study is to test the method of timely optimal cerebral perfusion pressure value or optimal arterial pressure value in intensive care patients after brain surgery. The main question it aims to answer are: how long it takes to identify optimal cerebral perfusion value when arterial blood pressure is changing within safe physiological limits. Objectives of the study 1. To perform a prospective observational study by collecting multimodal physiological brain monitoring data: intracranial pressure (ICP), arterial blood pressure (ABP), End-tidal carbon dioxide (ETCO2), cerebral blood flow velocity (CBFV), ECG. 2. To perform a retrospective analysis of the accumulated clinical monitoring data, in order to create an algorithm for the identification of informative monitoring data fragments, according to which it would be possible to identify the optimal cerebral perfusion pressure (optCPP) value in a limited time interval (within a few or a dozen minutes). 3. To perform a retrospective analysis of accumulated clinical monitoring data, determining correlations of cerebral blood flow autoregulation and optCPP-related parameters with the clinical outcome of patients and with the risk of cerebral vasospasm or cerebral ischemia.
For stroke patients, early initiation of therapy typically yields the best functional outcomes. Rehabilitation of stroke patients immediately after hospitalization minimizes deleterious effects of immobility and facilitates restoration of function. The investigators are testing if coordinated efforts between the medical and rehabilitation disciplines may improve stroke patient's functional recovery and subsequent follow-ups after discharge.
The goal of this clinical trial is to compare a telemedicine neurologist staffing model to a traditional on-board model in patients being assessed for suspected acute stroke on a mobile stroke unit.
Background: Despite the capability of emergency surgery to reduce the mortality of severe spontaneous intracranial hemorrhage (SSICH) patients, the effect and safety of surgical treatment for severe spontaneous intracranial hemorrhage (SSICH) patients receiving long-term oral antiplatelet treatment (LOAPT) remains unclear. In consideration of this, the cohort study is aimed at figuring out the effect and safety of emergency surgery for SSICH patients on LOAPT. Methods: As a multicenter and prospective cohort study, it will be conducted across 7 representative clinical centers. Starting in September 2019, the observation is scheduled to be completed by December 2022, with a total of 450 SSICH patients recruited. The information on clinical, radiological, and laboratory practices will be recorded objectively. All of the patients will be monitored until death or 6 months after the occurrence of primary hemorrhage. Study Design: In this study, two comparative cohorts and an observational cohort will be set up. The primary outcome is the effect of emergency surgery, which is subject to assessment using the total mortality and comparison in the survival rate of SSICH patients on LOAPT between surgical treatment and conservative treatment. The second outcome is the safety of surgery, with the postoperative hemorrhagic complication which is compared between the operated SSICH patients on and not on LOAPT. Based on the observation of the characteristics and outcome of SSICH patients on LOAPT, the ischemic events after discontinuing LOAPT will be further addressed, and the coagulation function assessment system for operated SSICH patients on LOAPT will be established. Objective: In this study, investigators will estimate the effect and safety of emergency surgery for SSICH patients on LOAPT, which will provide an evidence for management in the future.
The purpose of this research study is to evaluate the safety and outcomes associated with the use of IRRAflow® System catheters in externally draining intracranial fluid to reduce intracranial pressure. This study will be comparing the IRRAflow® system to standard of care catheters used in the same procedure. The IRRAflow® system is FDA approved for this procedure.
The purpose of the study is to provide a first assessment of safety, tolerability and efficacy of Ir-CPI, administered on top of standard-of-care, on secondary brain injury in patients with spontaneous intracerebral haemorrhage.
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 SIM0355-201 trial is a multicenter, randomized, double-blind, placebo-controlled exploratory clinical trial with the main study objective of evaluating the safety and tolerability of different doses of Edaravone Dexborneol concentrate for injection combined with conventional medical therapy in patients with cerebral hemorrhage. The subject had a clinical diagnosis of cerebral hemorrhage, within 6-24 hours from stroke onset to start of study treatment, with the bleeding site in basal ganglia and a hematoma volume ≤ 30 ml at the bleeding site. The trial was divided into two periods (Period A and Period B), with Period A being a dose escalation period divided into two dose levels: the first dose level group (Dose 1 group: Synbixin 37.5 mg; placebo group) and the second dose level group (Dose 2 group: Synbixin 62.5 mg; placebo group).
Disorders of consciousness (DOC) refers to the persistent loss of consciousness after 28 days in patients with brain injury caused by trauma, stroke, or hypoxia. It includes coma, vegetative state, and minimally conscious state. At present, there is no effective treatment for DOC. Only one RCT study of amantadine has proved that it may be effective for the treatment of DOC. In recent years, more evidence has shown that neuromodulation technology is beneficial to the recovery of DOC. Cervical spinal cord stimulation surgery is a new treatment method for patients with DOC. Electrodes are implanted in the high cervical spinal cord C2-C5. By adjusting different electrical stimulation parameters, it has a wake-promoting effect. In this study, patients were selected into the spinal cord stimulation group and the conventional treatment group according to the wishes of their families. The patients in the spinal cord stimulation group were given 21 days of cervical spinal cord stimulation treatment on the basis of conventional brain rehabilitation. Patients were followed up routinely and completed designated examinations at 12 months to determine the safety and efficacy of cervical spinal cord stimulation therapy.
