Active clinical trials for "Hypoxia-Ischemia, Brain"

To determine effectiveness of therapy to improve neurodevelopmental outcomes in infants with mild HIE. To determine the adverse effects of Therapeutic Hypothermia (TH) in mild HIE on the neonate and his/her family. Determine heterogeneity of the treatment effect across key subgroups obtained in the first 6 hours after birth prior to the decision to initiate therapy.

Ammonia is a waste product of protein and amino acid catabolism and is also a potent neurotoxin. High blood ammonia levels on the brain can manifest as cytotoxic brain edema and vascular compromise leading to intellectual and developmental disabilities. The following aims are proposed: Aim 1 of this study will be to determine the chronology of biomarkers of brain injury in response to a hyperammonemic (HA) brain insult in patients with an inherited hyperammonemic disorder. Aim 2 will be to determine if S100B, NSE, and UCHL1 are altered in patients with two other inborn errors of metabolism, Maple Syrup Urine Disease (MSUD) and Glutaric Acidemia (GA1).

Hypoxic-ischemic encephalopathy is the most common cause of neurological damage in the neonatal period. It has an incidence of about 1.5-2.5% of livebirths in developed countries. It is associated with a high rate of mortality and morbidity. Major neurological outcomes such as cerebral palsy, mental retardation, learning disabilities, epilepsy occur in approximately 25% of survivors. The diagnostic and prognostic tools currently available for enrollment have limitations and additional reliable biomarkers are needed for all phases of clinical management. Sarnat staging has taken on a role in identifying those infants who may benefit from treatment of hypothermia, resulting in the need for neurological evaluation and staging within 6 hours of life. Therapeutic hypothermia is still the best therapeutic treatment. A new tool in neuroscience research is represented by micro-ribonucleic acid (microRNA) profiling. The presence of microRNAs in blood, urine and saliva and the ability to measure their levels non-invasively has opened new doors in the search for peripheral biomarkers for the diagnosis and prognosis of neurodegenerative diseases and also as possible pharmacological targets. The aim of the present study is to analyze a specific cluster of miRNAs selected from data obtained by macroarray (NGS Pannel) on the entire microRNAome in healthy newborns with normal cord arterial pH value (7.26-7.35) as control cases and in newborns with fetal metabolic acidosis with a pH threshold value lower than 7.12 of the blood gas analysis from cord arterial blood. This latter group will be further stratified into two groups, neonates who will practice therapeutic hypothermia according to current guidelines and a further group who will not practice therapeutic hypothermia. This study will make a further international contribution in evaluating and identifying the potential of microRNAs as diagnostic and prognostic biomarkers in perinatal asphyxia and hypoxic ischemic encephalopathy. Furthermore, the study aims to identify specific microRNA sequences as new possible markers to be used as an additional parameter for the enrollment of therapeutic hypothermia, especially in cases of mild hypoxic-ischemic encephalopathy.

The objective of this study is to estimate the feasibility and safety of early weaning from ICU treatment in patients after cardiac arrest and an early (< 12 h) favourable EEG pattern (indicating no or mild postanoxic encephalopathy).

This is a feasibility study to begin investigating the possibility that early use of near vision glasses will improve vision in infants at risk of Cerebral Visual Impairment (CVI), leading to further improvement in other areas of development. This active intervention, starting at either 2 or 4 months of age (depending on randomisation), could be more effective than waiting until a problem is detected before giving glasses. As this is a feasibility study, the investigators are looking at a small sample of babies (n=75) to see whether their parents/carers are willing to take part in a 3-arm study comparing two differently timed interventions to a control group, as well as looking at different aspects of the research plan in preparation for a larger final study.

To study the safety and efficacy of intranasal administration of exosomes derived from mesenchymal stromal cells on long-term neurodevelopmental outcome in extremely low birth weight infants born at gestational age 25/0-27/6 weeks.

The aim of our study is to investigate changes of brain perfusion and elasticity in neonates during the time that a neonate is adapting to live outside the womb and during diseases that are suspected to affect neonatal brain perfusion. We use contrast enhanced ultrasound (sulphur hexafluoride) and ultrasound-assisted elastography to evaluate the state of brain perfusion. We will study neonates recruited from the Neonatal Units of Turku University Hospital.

The purpose of this research study is to gather more information on how eye injury is related to a baby's future development and see if eye function and brain test results can be used, along with current measures, to better diagnose and treat babies with hypoxic-ischemic encephalopathy (HIE). Participants will undergo up to two eye exam sessions, involving both Visual Evoked Potential (VEP) and Electroretinogram (ERG) exams.

The study aims to identify factors that predict the medium and long-term outcome of patients with disorders of consciousness (DOC) undergoing early neurological rehabilitation. In this prospective, observational study, 130 DOC patients are going to be included (36 months). At study entry, different routine data, disease severity and functional status are documented for each patient. In addition, MRI, EEG and evoked potentials are measured within the first week. The level of consciousness is recorded with the Coma-Recovery-Scale-Revised and serves as the primary outcome parameter. Complications, comorbidities, functional status and leve of consciousness are assessed weekly. After eight weeks, the measurement of the MRI, the EEG and the evoked potentials are repeated. After 3, 6 and 12 months, the Glasgow Outcome Scale-Revised is used to followed up the current status of the patients.

The NSR-DEV study is a longitudinal cohort study of around 280 Neonatal Seizure Registry participants that aims to evaluate childhood outcomes after acute symptomatic neonatal seizures, as well as examine risk factors for developmental disabilities and whether these are modified by parent well-being.
