Filter by:A phase I study to test the feasibility and safety of treatment with metformin in infants affected by hypoxic ischemic encephalopathy (HIE) or prematurity-related brain injury
A longitudinal study evaluating the predictive ability of near infrared spectroscopy to predict brain injury in infants with hypoxic ischemic encephalopathy. Data will be analyzed at two different time periods, at discharge and again at 2 years of age.
There have been many studies on the use of running training in older children to improve gait development in children with cerebral palsy. The aim of our study was to conduct early treadmill training in infants who were highly suspected of cerebral palsy and to follow up on their long-term gait development.
The main goal of this study is to quantitatively assess the sucking and feeding activity of infants at high risk of neurological impairment (preterm infants and term infants at risk of abnormal neurodevelopment) during oral sucking and feeding and correlate it with their underlying neurological impairment for the early diagnosis of brain injury.
Cerebral oxygen desaturation during cardiac surgery measured using near infrared spectroscopy (NIRS) derived cerebral oximetry has been associated with significant postoperative morbidity. If significant desaturation occurs during this period, it may represent an ideal opportunity to further optimize the postoperative care of these patients.
The primary objective of this multicenter observational study is to determine the effect size of the relationship between DCI and neuropsychological impairment 14-28 days and 3 months after aSAH. Secondary objectives are the feasibility to administer and the validity of the MoCA in an intensive care unit setting, as well as the test/retest reliability of the MoCA in patients with acute brain damage in absence of aSAH.
The aim of this study is to assess the feasibility of using the Life Recovery Systems ThermoSuit Device to induce therapeutic hypothermia (32-34°C) in victims of ischemic stroke. This feasibility clinical study will enroll a total of 30 patients with acute ischemic stroke at four clinical centers. Subjects will receive hypothermia plus conventional therapy (such as IV-tPA and/or neurothrombectomy therapies if indicated). Endpoints will include feasibility of cooling, adverse events, and neurological recovery in comparison with matched historical controls.
Introduction Aneurysmal subarachnoid hemorrhage (aSAH) is bleeding around the under surface of the brain caused by rupture of an aneurysm arising from a blood vessel. Stroke may occur in approximately one third of patients as a result of narrowing of the blood vessels around the brain, following aSAH. One theory as to why this may happen is because bleeding around the base of the brain damages particular cells (neurons) that control blood flow around the rest of the brain. These neurons may control blood flow by releasing a neurotransmitter called Acetyl Choline (ACh). Our hypothesis is that damage to these neurons may prevent the production of ACh, which then causes reduced blood flow and stroke if left untreated. By stimulating these neurons, we aim to investigate whether it is possible to improve the blood flow around brain and ultimately prevent strokes in patients following subarachnoid haemorrhage. Donepezil, a drug widely used in dementia, inhibits the brain's natural break down of ACh. We predict that by increasing the amount of Ach in these neurons, donepezil may improve blood flow to the brain, reducing the chance of developing stroke. Trial Protocol All patients admitted to St George's hospital with a confirmed aneurysmal subarachnoid haemorrhage between the ages of 18 and 85 years old will be invited to participate in the trial. The protocol has been designed to take place around the patients' aneurysm treatment, which is performed under general anesthesia (GA). Recruited participants will be anesthetized for their aneurysm treatment and then enter the study. All trial participants will have a Xenon CT scan under GA to assess brain blood flow prior to having treatment of their aneurysm. Patients randomized to donepezil treatment will receive a loading dose of 20mg via a feeding tube immediately after their Xenon scan. Patients in the control group will not receive the drug. All patients in the trial will undergo repeat Xenon perfusion scanning under GA between 3 and 4 hours after their first scan, which coincides with the completion of their aneurysm treatment. Those in the donepezil group will then receive a daily dose of 5 mg for a period of 21 days. All aspects of care other than those related to the trial will be the same as for any other subarachnoid haemorrhage patients. Patients (or their legal representative for those unable to consent) will be able to decline participation in the trial or withdraw at any point.
The investigators will test the central hypothesis that DFO treatment after SAH may improve cerebrovascular regulation, mitigate ischemic neural injury, and serve as an effective neuroprotectant against delayed ischemic injury after SAH.
Dexmedetomidine is a unique sedative medication able to provide sedation without causing respiratory depression and maintaining neurological functions. Patients having an acute ischemic stroke and need to undergo endovascular therapy require constant assessment of their neurological status prior, during and after the interventional procedure. In this study the investigators will compare the efficacy of Dexmedetomidine to other standard sedative medications in providing optimal sedative effect while maintaining neurological function.
