The Neu-Prem Trial: Neuromonitoring of Preterm Newborn Brain During Birth Resuscitation
Neurologic ManifestationsPremature Birth2 moreThe purpose of this study is to characterize the normal brain function of premature infants (23 to 31+6 weeks GA) during birth transition and through the first 72 hours of life.
Correlation of Risk Factors and Severity of Hypoxic-ischaemic Encephalopathy
Hypoxic Ischaemic EncephalopathyThe first aim of this study is to analyse perinatal risk factors leading to hypoxic ischaemic encephalopathy in term and near term neonates born in Switzerland who were admitted to the neonatal and intensive care units offering hypothermia therapy. Further, investigators would like to analyse the influence of these perinatal risk factors on the severity of encephalopathy during and after hypothermia therapy.
Cytokines Associated With Cord Blood Cell Therapy for Neonatal Encephalopathy
Neonatal Encephalopathy (Neonatal Hypoxic-ischemic Encephalopathy)This is a observational study to assess the effects of and to explore the mechanisms of autologous umbilical cord blood cell therapy for neonatal encephalopathy by way of measuring serum cytokines.

Brain Hypoxia IschemiaThis study uses a CPOM Optical neuromonitor to assess the relationship between brain cytochrome C oxidase, cerebral oxygen saturation and blood pressure during surgery performed under general anesthesia.
MRI of Neonate With HIE Before and During the Moderate Hypothermia
Hypoxic-Ischemic EncephalopathyModerate hypothermia has been demonstrated to be the effective treatment for neonates with hypoxic-ischemic encephalopathy (HIE). However, few studies reveal the actual alterations in physiological parameters (i.e. brain temperature and cerebral blood flow) of neonates undergoing cooling, especially for HIE lesions. Therefore, this project aims to utilize the magnetic resonance imaging (MRI), i.e. MR thermal imaging and phase contrast MRI to measure the changes of these parameters before and during hypothermia; and then make comparisons with the routine nasopharyngeal and rectal temperature. All these would provide in vivo quantitative data for therapeutic evaluation and promote the optimization.
THE ROLE OF CARDIAC MARKERS IN HYPOXIC ISCHEMIC ENCEPHALOPATHY IN LONG-TERM NEURODEVELOPMENTAL FOLLOW...
Hypoxic-Ischemic EncephalopathyNewborn MorbidityIn this study, the correlation of cardiac marker values (Troponin I, CK, CK-MB) measured before treatment with the long-term neurodevelopmental score of newborns diagnosed with perinatal asphyxia and treated with therapeutic hypothermia with a diagnosis of hypoxic ischemic encephalopathy (HIE) will be evaluated. Physical examination, laboratory (especially cardiac markers), aEEG findings and diffusion MRI findings of babies who have been hospitalized in the neonatal intensive care unit between 2015-2020 due to respiratory distress and who have undergone perinatal asphyxia but have undergone therapeutic hypothermia treatment will be recorded from their files in the hospital system. The neurological evaluations and neurodevelopmental scores of the babies in the follow-up in the neonatal high risk follow-up clinic after discharge will be recorded from their files.
Antenatal and Intrapartum Risk Factors Associated With Neonatal Hypoxic Ischemic Encephalopathy...
Neonatal Hypoxic Ischemic EncephalopathyPerinatal asphyxia is a major cause of hypoxic Ischemic encephalopathy (HIE), perinatal death and long term neurodisability. This can be devastating for the individual and their family; the healthcare and litigation costs notwithstanding. In recent years have attempted to quantify the effect, and wider impact of intrapartum compromise, as well as the underlying mechanisms for it. After a poor outcome related to intrapartum care parents and healthcare practitioners often strive to understand whether the event could have been predicted and/or prevented. This can be difficult to answer, at least partly related to the heterogeneous fetal response to perinatal asphyxia. Mothers and the maternity service are increasingly encouraged to personalize care and their choices around the birth process, however the information required to guide these choices is most often missing. This makes it difficult for women and professionals to make an informed choice about their care, including the safest mode of birth for them and their baby. Aim of the study: Identifying antenatal and intrapartum risk factors associated with neonatal hypoxic ischemic encephalopathy.
Long Term Prognostic of Neonatal Hypoxic Ischemic Encephalopathy With Hypothermia Treatment
Ischemic-Hypoxic EncephalopathyThe primary objective is to evaluate neonatal characteristics, and biological and clinical investigations as predictive factors of death, or of severe and moderate neurodevelopmental disability at 3 years, in a large population-based cohort of full-term and late preterm neonates with moderate or severe HIE. Contrary to most previous studies which have often analyzed the accuracy of one factor among all other clinical investigations, the investigators objective's is to seek a relevant combination of several factors among the following list: Neonatal characteristics: gestational age and birthweight, maternal disease, acute intrapartum event, delivery mode, acidosis, neurological examination, place of birth and neonatal transfer Laboratory investigations: pH, lactates and new biological markers as detailed below Clinical investigations: aEEG, EEG, MRI, diffusion-weighted MRI
MRI Thermal Imaging of Infants Undergoing Cooling for Hypoxic Ischemic Encephalopathy(HIE)
Hypoxic Ischemic EncephalopathyHundreds of babies in the world are being treated with brain cooling to prevent brain injury after they lose oxygen at birth. This study will use the newly developed information from the magnet resonance image to determine the actual temperature of the brain. This will enable us to determine if the brain is being uniformly cooled and if techniques that provide cooling need to be changed to improve the injury prevention from cooling.
Asphyxia Associated Metabolite Biomarker Investigation 2
Birth AsphyxiaFollow-up of participants of AAMBI1 study at age of at least 2 years. AAMBI1(ClinicalTrials.gov ID: NCT03354208): Verification of biomarkers in a human population for their ability to diagnose the severity of neonatal asphyxia. These biomarkers linked to asphyxia have been identified in animal studies.
