Active clinical trials for "Hypoxia-Ischemia, Brain"

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).

The purpose of the research is to determine if the Hepatitis B vaccine after birth provides enough protection after cooling for Hypoxic Ischemic Encephalopathy (HIE). To do this, Hepatitis B titers (blood sample) would be taken before, during, and after administering of the Hepatitis B vaccine series to measure efficacy of the vaccine.

The TIME study is a randomized, controlled trial to evaluate impact on early measures of neurodevelopment and the safety profile of therapeutic hypothermia in term neonates with Mild Hypoxic-Ischemic Encephalopathy who are < 6 hours of age. Neurodevelopmental outcome will be assessed at 12-14 months of age. The study will enroll 68 neonates randomized to therapeutic hypothermia or normothermia across 5 centers in California.

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

The goal of this single centre observational study is to use near-infrared spectroscopy (NIRS) monitoring to investigate cerebral oxygenation in two groups of newborn infants who are at high risk of brain injury. The NIRS monitor used in this study will be the Masimo O3 regional oximeter with neonatal sensors. Near-infrared spectroscopy (NIRS) monitoring uses near-infrared light to measure oxygen levels in the brain tissue (cerebral oxygenation). It provides information about blood flow to the brain and the balance between oxygen supply and demand in the brain tissue. It is non-invasive, safe and used routinely to monitor term and premature babies in the neonatal intensive care unit (NICU). This study will recruit two groups of infants admitted to the NICU who are at risk of brain injury in the newborn period, namely: Term and near-term babies who are undergoing cooling treatment (therapeutic hypothermia) for moderate to severe hypoxic ischaemic encephalopathy (HIE). Preterm babies who are born extremely prematurely (before 28 weeks of pregnancy). In the term/near-term group, the primary aims of the study are: To investigate if cerebral oxygenation during and after cooling treatment relates to markers of brain injury detected on detailed brain scans (MRI and MRS scans). To describe any changes in cerebral oxygenation which occur during and after seizures (fits) in babies undergoing cooling treatment. In the preterm group, the primary aims of the study are: To investigate if any changes in cerebral oxygenation occurring during skin-to-skin care are different in premature babies with brain injury (bleeding or cysts in the brain seen on ultrasound scan) compared to babies without these changes. To investigate if cerebral oxygenation at 36 weeks corrected gestational age differs in babies with bronchopulmonary dysplasia (BDP, a chronic lung disease of prematurity) compared to babies without BPD.

A phase 1 study investigating the tolerability and pharmacokinetics of caffeine citrate in neonates with hypoxic ischemic encephalopathy receiving therapeutic hypothermia. This study is an essential first step to develop caffeine as a kidney protective medication in this in this vulnerable group of newborns.

A randomized controlled study was conducted to explore the efficacy of early transcranial direct current stimulation (tDCS) and repetitive transcranial magnetic stimulation (rTMS) to promote wakefulness in patients with disorder of consciousness (DOC). In order to improve the prognosis of DOC patients with nontraumatic brain injury, we compared the effects of tDCS and rTMS on clinical behavior and neurophysiological performance, and selected a wake-up technique that could improve the prognosis of DOC patients with nontraumatic brain injury as early as possible, so as to reduce the pain of patients and their loved ones, and to reduce the economic burden of society and families.

Background the research proposed herein is in line with the Swedish Research Council's current focus on International collaborations and postdoctoral work abroad. In this case the child brain and translational and clinical infant brain research. Neonatal hypoxic ischemic encephalopathy in term infants constitutes a serious health problem, not the least due to its often life-long consequences in the form of cerebral palsy and other forms of brain dysfunction. An estimated 3-5 of every 1000 live term births are affected, a quarter of which with severe symptoms; 10-30% of the affected children do not survive, 30% suffer life-long disabilities. The incidence may be 10-fold higher in the developing world. In Sweden, an estimated 200 children are born each year with hypoxic ischemic asphyxia or oxygen deprivation during delivery of a severity necessitating treatment, in order to reduce future handicap. Not only the brain, but also other organs, such as the heart, liver or kidney can be damaged by hypoxic ischemia. In clinical trials, proof has been obtained that cooling can have positive effects counteracting brain injury induced by oxygen deprivation (asphyxia). Recent research suggests that cooling may also have a positive effect in stroke during the pre-treatment/transportation to hospital phase. PCM. A material with phase change properties (PCM) can be a chemical element, a solution or a substance with high melting energy. It melts/solidifies at a precise temperature and can store considerable amounts of energy (heat) before changing from one phase to another. The study group have used elements or solutions that change between solid and fluid phases within a narrow temperature interval. The most common use of PCM today is for energy storage, accomplished by having the PCM change between solid and fluid phases. Phase changes that include other PCMs, high temperatures and/or gas phases are less useful in medical applications due to the need of either large volumes in a low pressure setting or smaller amounts in a high pressure setting, increasing the risk for mistakes or secondary injury to medical staff or patients. For the clinical purposes of hypothermic treatment described here, the Glauber salt-based PCM in a mattress form developed by the applicant has near ideal properties; it is completely safe, does not cause over-cooling, can be reused many times, eliminates cooling fluctuations, is easy to handle and biodegradable.

The goal of this clinical trial is to explore the effect of FDA-approved antiseizure drugs in the brain connectivity patterns of severe acute brain injury patients with suppression of consciousness. The main questions it aims to answer are: Does the antiseizure medication reduce the functional connectivity of seizure networks, as identified by resting state functional MRI (rs-fMRI), within this specific target population? What is the prevalence of seizure networks in patients from the target population, both with EEG suggestive and not suggestive of epileptogenic activity? Participants will have a rs-fMRI and those with seizure networks will receive treatment with two antiseizure medications and a post-treatment rs-fMRI. Researchers will compare the pretreatment and post-treatment rs-fMRIs to see if there are changes in the participant's functional connectivity including seizure networks and typical resting state networks.

Some patients with refractory cardiac arrest can be saved by ECMO-treatment. However predictors defining which patients can be saved, and not, is missing. This shall be evaluated together with neurological prognostic factors during ECMO treatment. Long term cognitive function will be evaluated by physical examination and standardized tests in survivors. Costs will be assessed. Infection rates in patients will be studied.
