Cerebral Oxygenation and Autoregulation in Preterm Infants
Intraventricular Hemorrhage of PrematurityComplications of PrematurityPremature infants are at high risk for variations in blood pressure and oxygenation during the first few days of life. The immaturity of the premature brain may further predispose these infants to death or the development of neurologic problems. The relationship between unstable blood pressure and oxygen levels and brain injury has not been well elucidated. This study investigates the utility of near-infrared spectroscopy (NIRS), a non-invasive oxygen-measuring device, to identify preterm infants at highest risk for brain injury or death.
Early NCPAP Before Surfactant Treatment in Very Preterm Infants With RDS
Nasal Continuous Positive Airway Pressure,Preterm Infants,3 moreWe hypothesis a period of early NCPAP before surfactant treatment is effective for treating RDS and preventing BPD in very premature infants.
The Use of Methadone in Newborn Infants
Premature Birth of NewbornCritically IllThis proposed investigation will test the following hypotheses: 1) Enzymatic activity of CYP2B6 characterized by the formation clearance of methadone to EDDP (CLf,EDDP), is directly related to both gestational and postnatal age; 2) variations in the CYP2B6 gene (SNPs) are associated with variable activity of the CYP2B6 enzyme (as measured by the formation clearance, CLf,EDDP), and 3) the elimination rate of methadone and its major metabolite EDDP in neonates is dependent on the glomerular filtration rate and therefore on the stage of development (defined by both gestational and postnatal age). The investigators propose to develop a PK model for methadone dosing in neonates that takes into account both developmental stage and genetic variability. The long-term goal of the proposed investigations is to improve dosing of methadone in neonates exposed to opioids in utero or post-natally, leading to improved control of their withdrawal syndrome and decreased adverse drug reactions associated with the current use of methadone in these vulnerable patients. More immediately, the investigators will develop a PK model for methadone dosing based on relevant developmental and genetic characteristics. The acquired knowledge based on the proposed study will lead to a more efficacious treatment of pain or opiate withdrawal syndrome in newborn infants with a decreased chance of adverse drug reactions.
Helping Our Premature Infants ON to Better Motor Skills (HOP-ON)
Motor Development of Premature InfantsInfants born very premature have biological risk factors for later developmental coordination disorder. Parental stereotyping of infants as fragile and other environmental factors, such as spending long periods laying on their backs, also contribute to motor delay. This study aims to develop and evaluate a computer-based intervention (Helping Our Premature infants ON to better motor skills - HOP-ON) for parents of preterm infants. HOP-ON will model evidence based strategies to develop infants' fine and gross motor skills, and aims to reduce parental stereotyping. It is hypothesised that infants whose parents receive the HOPON CD-ROM/DVD and Booklet will have better motor skills at 12 months adjusted age compared to those whose parents receive a control CD-ROM/DVD and booklet. Parents of infants born at less than 32 weeks gestation (target n = 138) will be recruited prior to discharge from the neonatal unit and randomised to either HOP-ON or control. The primary outcome is motor score (Bayleys III) at 12 months adjusted age. Other outcomes are parental confidence and perceptions of infant capability at 3 months and quality of movement, infant growth, fine and gross motor movement and parenting stress at 12 months. Data will be analysed blind to study condition and on an intention to treat basis.
Stochastic Resonance Mattress (Physiological Interventions) and Biomarkers for Enhancing Neonatal...
Apnea of PrematurityThe purpose of this study is to explore physiological interventions and biomarkers for Apnea of Prematurity in newborn infants.
Hepcidin Levels in Preterm Infants
Preterm InfantsAnemia of Prematurity1 moreA recently isolated peptide hormone, hepcidin, is thought to be the principal regulator of iron homeostasis. Hepcidin acts by limiting intestinal iron absorption and promoting iron retention in reticuloendothelial cells. The aims of this study were to determine serum hepcidin levels in preterm infants who receive blood transfusion and preterm infants having sepsis, in order to assess possible relationships between hepcidin and serum iron, serum ferritin,in iron load situations.
Tidal Neonatal NO, Vitamins A and D, and Infant Lung Disease - The AD-ON Study
Term Delivery With Preterm LaborThird Trimester3 moreChildren born prematurely are of greater risk of developing chronic lung disease (Bronchopulmonary Dysplasia). With an increase in the amount of premature children, we expect an increasing number of children with BPD. Today we do not have many ways of predicting or treating this condition, and the children are usually in hospital for several months after birth. Many are dismissed with home oxygen. Children with BPD are typically often re-submitted to hospital with respiratory disease the first couple of years, and some of them have problems throughout childhood and into adulthood. Other scientists have found a correlation between BPD and Chronic Obstructive Pulmonary Disease (COPD). The condition as well as the treatment (steroids), are associated with great risk of adverse effects as Cerebral Palsy, blindness, deafness and mental retardation. The investigators wish to find a safe way to identify the children in greater risk of developing BPD, who could therefore benefit from a more intensive treatment.An early diagnosis would increase the possibility of predicting the prognosis. Other studies have proven a connection between both low vitamin A and D and high exhaled nitrogen oxide (NO) with lung disease. With this trial the investigators wish to make a reference material for NO and vitamins A and D in infants admitted to the neonatal department at two hospitals in Denmark, both with and without treatment with nasal Continuous Positive Airway Pressure. The investigators furthermore wish to describe an eventual connection between BPD and these factors by examining a large group of children on 7 specific occasions within the first two months of life and at a one year follow up.
Individualized Dosing of Nifedipine For Tocolysis in Preterm Labor
Preterm LaborThis study looks at the effects of a mother's genes and other characteristics (mother's age, baby's age, race, and other diseases) on the ability of nifedipine to end contractions and prevent an early delivery. This information will be used to decide what amount of nifedipine women need to best treat preterm contractions.
Assessing the Impact of Smoke-free Legislation on Perinatal Health in the Netherlands
Premature BirthPerinatal Mortality9 moreThe purpose of this study is to investigate whether there has been a change in perinatal outcomes following the phased smoking ban introduction (January 2004 for workplaces; July 2008 for bars and restaurants) workplaces in the Netherlands.
A Longitudinal Study of Effectiveness of Early Intervention for Preterm Infants
Premature BirthThe main purpose of this study is to extend the investigators' previous research to longitudinally examine the effectiveness of three early intervention programs: usual care program, clinic-based intervention program and home-based intervention program for very low birth weight preterm children at 3 and 4 years of age. Normal weight full-term children will also be included to serve as the reference group. Effectiveness assessments will include child, parenting, and transactions measures. Child outcome measures will include health status, growth, neurodevelopment and behavior; parenting outcome measures will include parental stress, competence, efficacy and family support; transactions outcome measure will include parent-child interaction procedures.
