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.\n\nIn 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.",[28,29],"Anoxia-Ischemia, Brain","Neonatal Encephalopathy",[28,31,32,33,34,35,36,37],"postpartum","Electroencephalography","Cerebral oxymetry","Near Infrared spectroscopy","EEG","NIRS","Neonate","RECRUITING","2026-05-12",{"date":41,"type":42},"2026-05-13","ACTUAL",{"date":44,"type":42},"2021-03-03",{"date":46,"type":22},"2027-01",{"name":48,"class":49},"Centre Hospitalier Universitaire, Amiens","OTHER",1,{"id":52,"slug":53,"hasResults":11,"nctId":54,"briefTitle":55,"officialTitle":56,"acronym":57,"eligibilityCriteria":58,"healthyVolunteers":59,"sex":17,"minAge":60,"maxAge":4,"enrollmentInfo":61,"targetDuration":4,"studyType":23,"phases":62,"briefSummary":63,"conditions":64,"keywords":68,"overallStatus":74,"whyStopped":4,"lastUpdateSubmitDate":75,"lastUpdatePostDateStruct":76,"startDateStruct":78,"completionDateStruct":80,"leadSponsor":82,"locationsCount":50},"100606607","assessment-of-structural-brain-changes-related-to-anoxic-coma-using-high-field-and-very-low-field-mobile-mri-100606607","NCT07177755","Assessment of Structural Brain Changes Related to Anoxic Coma Using High-field and Very Low Field Mobile MRI","Assessment of Structural Brain Changes Related to Anoxic Coma Using High-field (3T) and Very Low-field (0.064T) Mobile MRI - CUBE","CUBE","Inclusion criteria :\n\nCOMA PATIENTS\n\n* Adult patients (male or female ≥ 18 years).\n* Coma, as indicated by a Glasgow Coma Scale (GCS) ≤ 8 (motor score ≤ 2) immediately after CA resuscitation and before sedation onset.\n* Written informed consent from patient's legal representative.\n* Affiliation to the French social security system\n\nHEALTHY VOLUNTEERS\n\n* Adult patients (male or female ≥ 18 years).\n* Written informed consent.\n* Affiliation to the French social security system\n\nExclusion criteria :\n\nCOMA PATIENTS\n\n* Brain death.\n* Coma explained by other cause than CA.\n* Pregnancy.\n* MRI contraindication: medical material not MRI compatible.\n* Hemodynamic instability or respiratory failure precluding patient's transport and MRI scanning.\n\nHEALTHY VOLUNTEERS\n\n* Pregnancy.\n* MRI contraindication: medical material not MRI compatible.\n* Volunteers who do not wish to be informed of an abnormality detected on MRI a posteriori",true,"18 Years",{"count":21,"type":22},[25],"Standard predictors of outcome after cardiac arrest (CA) have substantial limitations in terms of reliability and generalizability. By providing brain structural connectivity maps, or connectomes, advanced MRI techniques, operating through high-strength magnetic field (HF; 1.5 to 3-T), have precisely revealed white and grey brain matter damages induced by CA, and have demonstrated the high sensitivity and specificity of these indicators for predicting neurological outcome after CA. However, HF MRI requires rigid safety precautions, highly trained technicians and patient transport to dedicated hospital imaging suites, hindering the implementation of these promising neuroimaging techniques in the setting of critical illness.\n\nInterestingly, a recent report demonstrates the capability of a proof-of-concept very low-field (VLF; 0.064-T) mobile MRI to obtain neuroimaging at the bedside in critically ill patients. Nevertheless, the spatial resolution of VLF-MRI seems low and there is no available evidence about the use of VLF-MRI to extract highly needed new predictors of neurological recovery based on critical brain structural connectomes.\n\nThe CUBE project holds the promise of providing a radical paradigm shift in the field of neuroprognostication of anoxic coma patients. The current proposal is a \"proof-of concept\" study which aims to compare for the first time, HF, VLF and enhanced VLF (recon-VLF) structural connectomes from anoxic coma patients and healthy subjects across the time (3 paired HF and VLF brain scan across the first two weeks after CA). To obtain recon-VLF data, the Investigators will use an ensemble of ground-breaking methods to increase the native spatial resolution of VLF-MRI data. The whole brain imaging dataset will be used to prepare future neuroprognostication studies based on fully bedside assessment of brain structural integrity after CA.",[65,66,28,67],"Anoxic Coma","Cardiac Arrest (CA)","Coma",[65,69,70,71,72,73],"Cardiac arrest","VLF MRI","HF MRI","structural brain","connectomes","NOT_YET_RECRUITING","2025-09-10",{"date":77,"type":42},"2025-09-17",{"date":79,"type":22},"2025-09-15",{"date":81,"type":22},"2029-03",{"name":83,"class":49},"University Hospital, Toulouse"]
