Habituation's Mechanisms in Preterm and Term Infants
HabituationPsychophysiological2 moreEach year in France, 7 % of newborns are born preterm (before 37 weeks of gestational age (GA)). The investigators called very preterm infants those who were born before 33 weeks of GA. These very preterm infants have a higher risk of developing neurological complications like developmental disabilities or cerebral palsy. To date, early assessment of these infants is difficult and not reliable enough to detect those who are at risks of developing neurological issues. Now, the investigators need to identify earlier these infants to provide them interventions to improve their development (physical therapy for example). Consequently, the investigators are examining a study whose aim is to assess preterm infants habituation. Habituation is the newborn ability to become familiar with new environmental stimulations (noise, light…). This habituation allows the newborn to maintain his sleep even at onset of a noise or light. To study this phenomenon in infants born preterm near to corrected term (around 40 weeks of postnatal GA), will allow us to better understand neurological development of these infants. The investigators plan to compare habituation skills of preterm infants near to their theorical date of birth (40 weeks of GA) to a population of infants born at term. The investigators will also study the link between habituation abilities and sleep quality as well as neurodevelopmental outcome at the corrected age of two years old.
A Clinical Efficacy and Safety Study of OHB-607 in Preventing Chronic Lung Disease in Extremely...
Bronchopulmonary DysplasiaChronic Lung Disease of Prematurity2 moreThe purpose of this study is to determine if an investigational drug can reduce the burden of chronic lung disease in extremely premature infants, as compared to extremely premature infants receiving standard neonatal care alone.
Longterm Outcome of Children With Neonatal Intra-Ventricular or Intra-Cranial Hemorrhage
Neonates PrematureIntraventricular hemorrhage (IVH) is the most commonly recognized cerebral lesion on ultrasound in extremely preterm infants. Papile classification is commonly used to grade the severity of IVH. Grade III-IV IVH and other lesions noted on ultrasound including periventricular leukomalacia (pvl) porencephaly, and ventriculomegaly are well Documented to be associated with adverse neurodevelopmental outcomes. However, the true impact of lower-grade IVH on the neurodevelopment of these extreme preterm infants has not been well described. Also Neurodevelopmental outcome for neonatal non-traumatic Intra Cranial Hemorrhage (ICH) is not well established. The aim of this study is to look retrospectively at babies with neonatal IVH or ICH and follow their radiological, cognitive, motor and functional outcomes. The study will focus on postnatal files, and on images performed as part of the child's follow-up during hospitalization and after discharge.
Physiological Phenotyping of Respiratory Outcomes in Infants Born Premature
Premature LungsThe purpose of this study is to examine if infants are more likely to suffer from respiratory complications during their first year of life due to being born premature.
Development of a Developmental Prognostic Tool for the Premature Child Based on Automated Spontaneous...
Premature BirthPrematurity is a major risk factor for poor neurodevelopmental outcomes. The clinical and neuroradiological evaluations proposed during the neonatal period to assess the developmental prognosis of children born prematurely are not sensitive and nor specific. The analysis of spontaneous motor activity by Prechtl's method has a better predictive value but is currently unfeasible in clinical routine. The study's principal objective is to describe the standardized values of complexity, variability, and fluidity of general movements.
Detection of CardioRespiratory Events Using Acoustic Monitoring in Preterm Infants on CPAP
Apnea of PrematurityThis is an observational, proof-of-concept, feasibility study where 50 preterm infants with gestational age < 32+0 weeks will be recruited from the neonatal intensive care unit (NICU) at the Montreal Children's Hospital. The study's primary objective is to describe the relationship between respiratory acoustics and airflow and determine the reliability of a novel respiratory acoustic sensor at detecting breathing sounds in preterm infants. The study's secondary objectives are: To compare transthoracic impedance, respiratory inductive plethysmography and an inertial measurement unit for the detection of respiratory efforts in preterm infants. To evaluate the feasibility and accuracy of a novel, non-invasive method for continuously detecting and differentiating cardiorespiratory events in preterm infants on CPAP by integrating measurements of respiratory effort with respiratory acoustic monitoring.
Investigation Into the Microorganisms in Pregnant Women
Cervical InsufficiencyPreterm BirthPregnant women with short cervical length (<25 mm) in second-trimester ultrasonographic assessment are at high risk for preterm birth, a major cause of perinatal mortality and morbidity worldwide. Some of these short-cervix women proceed to a more advanced stage manifested as a painless prematurely dilated cervix in the second trimester. It is not fully understood why some women have short cervical length or prematurely dilated cervix (cervical insufficiency), although evidence is mounting that there is an association between short cervical length and infection by microorganisms. The investigators hypothesize that the cervical microorganisms in pregnant women with a shortened or dilated cervix are different, compared with those in women with normal cervical length and a closed cervix.
Prevention of Stroke and Sudden Cardiac Death by Recording of 1-Channel Electrocardiograms
Sinus RhythmAtrial Fibrillation4 moreSingle-channel electrocardiograms (lead I of 12-lead surface ECG; 30 seconds) will be collected from subjects/patients at 11 clinical centers in Germany to train an Artificial Intelligence in the automatic diagnosis of regular and irregular heart rhythms. Heart rhythms of interest are normal sinus rhythm (SR), atrial fibrillation (AF), atrial premature beats (APBs), ventricular premature beats (VPBs), and nonsustained ventricular tachycardia (VT). Per diagnosis, 20,000 ECGs are required, for a total of 100,000 ECGs to be obtained from approximately 10,000 subjects/patients.
Can Cervical Stiffness in the Second Trimester Predict Preterm Birth in High-Risk Singleton Pregnancies?...
Preterm BirthPreterm birth (PTB), defined as delivery before 37 weeks gestation, is a common complication of pregnancy and affects up to 1 in 10 women in the UK. PTB is the leading cause of neonatal mortality and morbidity with babies born earliest being at the greatest risk. Identifying women at high risk of having a PTB and offering treatments and intervention to try and prevent this outcome is a huge priority in clinical practice and in government policy. The PRECISION study will explore the use of a new antenatal test of cervical stiffness to try and improve the recognition of women who may deliver early. Current clinical practice involves measurement of cervical length (CL) and fetal fibronectin in women known to be high risk for PTB. However recent research suggests these methods could be improved upon and we may be able to recognise women at risk more reliably and at an earlier stage in the pregnancy if we use cervical stiffness assessments. A licensed, CE-marked, vacuum-aspiration device called the Pregnolia system has been developed to give quantitative cervical stiffness index scores during pregnancy. This study will directly compare cervical length measurements and fetal fibronectin results with cervical stiffness, using the Pregnolia system, during the second trimester in women known to be high risk for preterm birth. The investigators will aim to explore the best possible predictive tool kit bundle for PTB using any combination of these assessments.
A RCT of CenteringPregnancy on Birth Outcomes and Maternal Inflammation
Preterm BirthThe purpose of the PIINC study is to identify differences in placental inflammatory lesions between women participating in group prenatal care versus standard prenatal care, and additionally, examine whether the frequency of placental inflammatory lesions differ by race and income. The investigators hypothesize that women participating in group prenatal care will have lower pro-inflammatory profiles compared to women in routine prenatal care.
