Active clinical trials for "Brain Ischemia"

Hypoxic-ischemic encephalopathy (HIE) due to perinatal asphyxia is common and often fatal. Therapeutic hypothermia reduces mortality and morbidity in infants with HIE. Even with the widespread use of therapeutic hypothermia, ~60% of infants with HIE die or have neurodevelopmental impairment. As a result, there is an urgent, unmet public health need to develop adjuvant therapies to improve survival and neurodevelopmental outcomes in this population. Caffeine may offer neuroprotection for infants with HIE by blocking adenosine receptors in the brain and reducing neuronal cell death. In animal models of HIE, caffeine reduces white matter brain injury. Drugs in the same class as caffeine (i.e., methylxanthines) have been shown to be protective against acute kidney injury in the setting of HIE. However, their safety and efficacy have not been studied in the setting of therapeutic hypothermia and their effect on neurological outcomes is not known. Since these drugs reduce injury to the kidney in infants with HIE, they may also reduce injury to the brain. This phase I study will evaluate the pharmacokinetics, safety, and preliminary effectiveness of caffeine as an adjuvant therapy to improve neurodevelopmental outcomes in infants with HIE.

This study aims to determine the safety of HB-adMSC infusion and treatment effects of HB-adMSC infusion on brain structure, neurocognitive/functional outcomes, and neuroinflammation after subacute and chronic neurological injury in adults.

A prospective, multi-center, single-arm study to evaluate the safety and efficacy of drug eluting balloon catheter for the treatment of patients with symptomatic intracranial atherosclerotic stenosis.

The aim of the biomedical research is to determine the informativeness and prognostic factors of surface electromyography by assessing the probability of recovery of balance and gait parameters in the second stage of rehabilitation of persons with cerebral infarction.

Neonatal anoxia-ischemia causes significant neurodevelopmental disorders. In this study the investigators want to better understand the interactions between the nervous and the hemodynamic cerebral systems during the adaptation of the neonate to ectopic life just after birth. Birth is an at risk situation of neonatal anoxic ischemia and the lack of objective criteria for cerebral tissue oxygenation has consequences on neuronal activity. Ph cord analysis is inadequate and only indirectly reflects the state of cerebral oxygenation. Both neuronal and vascular systems are part of the same functional entity and the analysis of their interactions is likely to reveal some early malfunctions of these networks. In this study, the investigators want to develop a multi-scale, multimodal approach that allows simultaneous interrogation of both neuronal and vascular compartments during the 15 minutes after delivery. The investigators will record, with the aid of a single sensor placed on the scalp of the child, the electroencephalogram and the cerebral tissue oxygenation. The investigators will measure interactions by means of correlation analysis between both signals.

The objective of the study is to compare the incidence of Hypoxic ischemic encephalopathy (all stages) among singleton term neonates (≥ 37 weeks) requiring resuscitation who will undergo Umbilical cord milking as compared to Immediate cord clamping.

Neonates presenting with neurologic symptoms require rapid, non-invasive imaging with high spatial resolution and tissue contrast. The purpose of this study is to evaluate brain perfusion using contrast-enhanced ultrasound CEUS in bedside monitoring of neonates and infants with hypoxic ischemic injury. Investigational CEUS scan will be performed separately from clinically indicated conventional US, in the ICU. Subjects will be scanned with CEUS at two different time-points (at the time HII is first suspected or diagnosed and at time of MRI scan), separately from clinically indicated ultrasound. The CEUS scan will be interpreted by the sponsor-investigator. The study will be conducted at one site, The Children's Hospital of Philadelphia. It is expected that up to 100 subjects will be enrolled per year, for up to two years, for a total enrollment of up to 200 subjects.

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.

There is no international application of infant running stimulation system to evaluate the brain injury in children with various stages of nerve and motor development in a large sample of studies. The study of neonatal brain injury is only limited to intraventricular hemorrhage(IVH),periventricular leukomalacia(PVL), Down's syndrome(DS), premature birth of these four conditions, and the number of samples in the single digits, there is no representative of the disease population. Therefore, from the newborn to the infant development of the critical period, the investigator will refer to the previous treadmill parameters set on the research results, optimize the application of neonatal treadmill. The study hypothesized that neonatal treadmill stimulation with brain-injured children could improve his / her staggered gait characteristics and long-term nerve development through large sample data. It is important to preserve and analyze the gait characteristics and the changes of nerve development in every stage of growth and development of neonates with brain injury so as to provide clinical evidence for rehabilitation intervention. It is of great significance to judge whether this technique can be used in the early stage of brain injury in neonates.

An extension of the CORDMILK trial, the CORDMILK follow-up trial will evaluate the neurodevelopmental outcomes at 22-26 months age of term/late preterm infants who were non-vigorous at birth and received umbilical cord milking (UCM) or early cord clamping (ECC).
