Thyroid Function in Late Preterm Infants

Transient Hypothyroxinemia

Transient hypothyroxinemia (TH) is a condition characterized by low levels of serum thyroxine (T4) and normal levels of thyroid stimulating hormone (TSH). TH in premature infants has been found to be related to severity of illness. T4 levels in very low birth weight infants born prematurely has been found to be inversely correlated to severity of illness. In very low birth weight infants, TH has been associated with poor outcomes. Little is known about thyroid function in late preterm infants. Hypotheses: Ill late preterm infants will have lower total T4 levels than healthy late preterm infants. Total T4 and possibly TSH levels will be inversely correlated with short-term outcomes. Late Preterm infants born by cesarean section will have lower T4 levels compared to those born by vaginal birth.

The Biomarker Study

Preterm BirthPreterm Labor

Preterm birth (PTB) is a leading contributor to perinatal morbidity and mortality. While patients with preterm labor (PTL) are at an increased risk for PTB, not all PTL patients will deliver preterm. In patients with PTB, there is a high prevalence of 'intrauterine inflammation' as demonstrated by a large body of evidence. The presence of inflammation is noted by infiltration of inflammatory cells in the placenta and/or maternal fever in labor and/or elevation of cytokines in the amniotic fluid. Despite this significant association of inflammation with PTB, identification of women destined to deliver preterm by inflammatory markers in maternal blood has not been successful. To date, it has been difficult to determine which patients with PTL will experience PTB. Identification of biomarkers, such as high sensitivity C-Reactive Protein (hsCRP) as well as others such as sICAM, Pentraxin, sE-Selectin, and CxCL-10 in maternal serum and in placental cord blood, may help to serve three very important clinical aims. 1) Identification of novel biomarkers in maternal serum could help to distinguish those women with PTL who are most likely to deliver PTB. 2) These biomarkers may have a high negative predictive value and thus identify those women who are not likely to deliver preterm, avoiding undue hospital admission and medical therapies. 3) Select biomarkers in the mother and/or in cord blood may serve to identify those preterm neonates at greatest risk for adverse outcome. Through improved identification of these infants, studies with targeted therapies to reduce adverse neonatal outcomes in preterm neonates become feasible. This study involves a cohort assessment of women at risk for Preterm birth secondary to preterm labor, preterm premature rupture of membranes (PPROM), and cervical insufficiency (CI), between 22-0/7 and 33-6/7 weeks gestational age. We will obtain information regarding patients' pertinent past medical and obstetric history as well as small samples of maternal blood at up to four occasions, small samples of placental cord blood, a maternal saliva sample, and an infant buccal swab. We will follow each of these patient's pregnancy outcomes, and determine if there are any correlations between levels of certain biomarkers and latency to delivery as well as composite adverse neonatal outcomes. In women with PTB < 37 weeks, cord blood will be collected (as well as maternal saliva and an infant buccal swab) and biomarkers compared between those infants with and without specific adverse neonatal outcomes. Maternal saliva and buccal will be collected on all women and infants enrolled.

Va-Sense - Bacterial Vaginosis Once A Week Screening And Treatment To Reduce Infective Complications,...

Vaginal InfectionsBacterial Vaginosis3 more

The purpose of this study is to determine whether screening of pregnant women with history of previous preterm delivery, once a week, for bacterial vaginosis using VA-SENSE, and treatment of positive women will reduce the risk of spontaneous preterm birth. We will compare between the effectiveness of once a week screening and once during pregnancy screening.

Wales Electronic Cohort for Children

MacrosomiaLow Birth Weight3 more

The investigators are developing a research platform capable of improving children's health through the generation of knowledge from analysis of routinely collected data from within and outside the health service. The investigators are using the data that are routinely collected in Wales to answer specific questions about child health and well-being, with the aim of informing policy and practice in Wales, whilst also being internationally relevant. Routinely collected datasets are publicly funded, and have already been incorporated into the Secure Anonymised Information Linkage databank. The investigators are combining these datasets on children from health and social care to establish an anonymised Wales wide Electronic Cohort for Children (WECC). WECC will serve as the platform for future work in translating information into child population health policy. There are 35,000 births in Wales per year, and data are available for the previous ten years. Thus, WECC will be sufficiently powered to answer important social, economic and health policy questions. WECC will also act as a demonstration project which would inform the development of e-cohorts to support translational research across the life course and disease spectrum.

Common Neonatal Procedures Could Affect the aEEG in <30 Weeks of Gestational Age Preterms

Regional Blood FlowPremature Birth1 more

Very low birth weight infants has increased dramatically their survival. Survival without neurologic disturbance varies a lot between centers.There is evidence that fluctuations in cerebral blood flow influences the appearance of intraventricular hemorrhage and itself implies a detrimental neurologic developing.The electroencephalography is the result of electric base membrane activity on rest, and it's influenced by the blood flow either. The Amplitude-integrated electroencephalography is a novel tool, that is capable to be continuously used at the patient bed and is easily to be read by the trained clinician.The hypothesis is that common procedures as Surfactant instilation, Indomethacin and Aminophyline infusion as the appearance of apneas alters the aEEG register. It is a prospective study that tries to recruit 10 < 30 weeks of gestational age with aprofen consent to monitorize the aEEG since birth to the seventh day of live.

Cerebral Function Monitoring in Premature Infants

InfantNewborn7 more

This observational study tests the feasibility of enrolling subjects and obtaining an amplitude-integrated electroencephalogram (aEEG) within the first 72 hours of life, a second aEEG recording between 72-168 hours of life, and weekly thereafter up to 36 weeks post-menstrual age. It will enroll 85-100 infants between 401-1,000 grams birth weight OR between 23 0/7 and 28 6/7 weeks gestational age born at the 7 participating NICHD Neonatal Research Network sites.

Long-term Effect of The Mother Infant Transaction Program (MITP)

Premature Births

The purpose of this study is to investigate if a cost and time effective intervention in a previous RCT for preterm infants and their parents can reduce the parents experience of concern and stress, and improve the childrens development in various aspects at three years of corrected age. Hypothesis 1: The preterm born children of parents who were enrolled in the earlier RCT have a higher developmental level then preterm children of parents who received the usual treatment. Hypothesis 2: Parents who who were enrolled in the earlier RCT will have a lower level of stress and concern then parents who received treatment as usual.

Influenza Vaccine in Premature Infants

InfluenzaInfant1 more

Background. Influenza is increasingly recognized as causing severe respiratory illness in children. High-risk infants, like former premature infants, and particularly those with lung disease, have influenza hospitalization rates about five times higher than healthy children. Influenza vaccine does not protect young children against influenza as well as it does healthy adults. A small study that measured antibodies (proteins that protect against infection) to influenza suggested that premature infants get even less protection from influenza vaccine than full-term infants. More information about influenza vaccine in premature infants is needed. The overall goals of this project are to collect information about the how well the influenza vaccine induces antibody production, and to develop the collaborative network of centers necessary for a larger trial of influenza vaccine in premature infants. Objective and Hypotheses. The objective of this study is to measure the amount of protective antibody produced by influenza vaccine in premature (less than 30 weeks' [about 7 months] gestation at birth), extremely-low-birth-weight (1000 grams [2¼ pounds] or less at birth) infants. Influenza vaccine needs to be given yearly. We will assess premature infants during their first series of influenza vaccines. We hypothesize that the levels of antibody will be lower in premature infants receiving their first series of influenza vaccine than in full-term infants. Design. We will measure the immune response in premature and full term infants. During the 2007-2008 influenza season, a total of 92 subjects, divided among 2 groups (premature infants 6-17 months old receiving their first influenza vaccine series and full-term infants 6-17 months old receiving their first influenza vaccine series) will be recruited at a consortium of five centers (the University of Rochester, the University of Texas Southwestern Medical Center, Wake Forest University, the University of Miami and the State University of New York at Buffalo), receive 2 doses of influenza vaccine, and have antibody and immune cell responses to each vaccine component measured 4-6 weeks after the second dose of vaccine. Potential Impact. If this study and future investigations suggested ways to improve premature infants influenza vaccine responses, they could lead to changes in recommendations for the number or timing of vaccine doses or of the type of vaccine used in this high-risk group.
