Chronic stress has been proposed to be involved the development of western life-style diseases such as cardiovascular disease and type 2 diabetes (T2DM). At the same time chronic stress is also believed to cause psychiatric disease such as melancholic depression (MD)and anxiety disorders. Accordingly, humans born with low birth weight (LBW) (ei. less than 5,0 LB) display an increased risk for T2DM and MD. Studies suggest stress and adrenal stress hormones (glucocorticoids) (GCC) might be involved in the development of both of these conditions. Recent studies of animals born LBW suggest, that SSRI-compounds, usually employed in the treatment of MD-related diseases, reduces stress-responses and levels of stress hormones such adrenal steroids and at the same time has a positive influence on glucose metabolism. In present study, the investigators aim to measure levels of GCC and stress and assess glucose metabolism in healthy young men (20-35 years) born LBW (40 subjects). The volume and structure of a certain brain area (ie. hippocampus) involved in regulation of adrenal GCC and known to be malfunctioning in chronically stressed individuals will be assessed by magnetic resonance imaging (MRI). Further metabolic examination will be accompanied by MRI spectroscopy of liver and muscle fat content as well as total fat content (Dexa-scanning) and contents of fat in the abdomen (by MRI) . Psychiatric well-ness and symptoms will be characterized by well-established questionnaires such as MDI and SCL-92 and responses as regards blood pressure, heart rate and changes in basal plasma concentrations of GCC and Epinephrine will be assessed while performing a Stroop Stress Test. Finally, a 24 hour blood pressure profile test will be included. After this extensive examination program, subjects will be randomized to 3-4 months of treatment with either Escitalopram (an SSRI-compound) or Placebo. Subsequently, at the end of the treatment, the whole examination program will be repeated to detect potential beneficial changes. A group of young normal birth weight men (20 subjects) will serve as a healthy baseline group for comparison and will not be exposed to any medical treatment. This trial will add understanding to the mechanism underlying the development of type 2 diabetes and depression in LBW. Additionally, present trial might be capable of proposing a novel treatment strategy to prevent the development of these diseases in LBW man.
The purpose of this study is to determine if routinely recording fluid balance in sick neonates admitted to the pediatric ward is reliable and useful. The investigators' hypothesis is that it is not useful and reliable.
The purpose of this study is to examine if single skin cleansing with 0.25% chlorhexidine affects skin condition, temperature, and bacterial colonization in stable preterm (28-36 weeks gestational age) low birth weight (1001-2000 g) infants admitted in a health facility.
Low birth weight (LBW) status (< 10% for gestational age at birth) is associated with increased risk for diseases such as type II diabetes mellitus, hypertension, chronic obstructive pulmonary disease and coronary artery disease in adults, and represents one example of the "fetal onset of adult disease" hypothesis. Recent data strongly associates LBW status with impaired innate and adaptive immunity leading to increased risk for severe infections during adolescence or early adulthood. Animal studies suggest that the ratio of certain B lymphocyte subpopulations, the B1a and B1b cells, determines whether deficits in immunity occur. This study will determine the ratio of B1b to B1a lymphocyte subpopulations in the cord blood of infants born LBW in the late preterm to term gestations (> 34 weeks at birth) and compare those ratios with those of normal birth weight (NBW) controls in a nested case control study design. Furthermore, animal studies suggest that the expression patterns of CD5 and CD19 proteins determines the cellular phenotype of the B lymphocyte, that of a B1a or a B1b cell, and that the regulatory regions controlling their expression are epigenetically vulnerable. The investigators will therefore isolate DNA and RNA from both B lymphocyte subpopulations and determine whether epigenetic changes to the regulatory regions of the genes coding for CD5 and CD19 protein expression occur in LBW lymphocyte subpopulations as compared to the lymphocytes from NBW infants. This proposal will be the first human study to examine epigenetic determination of a maladaptive phenotype following LBW status at birth in a specific cell type leading to a specific impairment of innate and adaptive immunity.
Low birth weight (LBW; birth weight<2,500g) is the most important determinant of mortality and morbidity in the neonatal period. It is also a very important factor in predicting nutritional status, health and development in childhood. It even influences health in adult life, contributing to the vicious cycle of disease and poverty. The high rate LBW in DCs represents therefore a major public health problem. Maternal chronic energy deficiency is assumed to be a major determinant of the problem in these countries along with prenatal micronutrient deficiencies. A large body of recent evidence points out that multiple micronutrient supplementation as such has only a modest beneficial effect on fetal growth. Therefore, it is expected that providing these multiple micronutrients in a food supplement covering energy requirement needs of pregnant women will have an effect of public health importance on children's health. This study has the objective of improving children's health by improving birth outcome and fetal growth through the provision of a food supplement enriched in multimicronutrients during pregnancy. This research includes 2 constituents: 1. a pilot phase during which dietary behavior of pregnant women is assessed as a component for optimal fetal growth 2. a randomized, placebo-controlled trial, including 1300 pregnant women aimed at testing 2 hypotheses: supplementing pregnant women with a food supplement containing a multivitamin-minerals mix will improve fetal growth; improved fetal growth will have a positive effect on health and growth during infancy. The trial is planned in Hounde District, Burkina Faso, in collaboration with Centre Muraz, which plays a leader role in research and services providing at the district level and in policy recommendations at the national level. This will ensure that the study findings are incorporated into on-going district programs with possible replication at the national level. The research lasts from February 2006 to August 2009.
This trial tests the feasibility of enrolling 60 extremely preterm infants in a randomized, double-blinded study of blood pressure management within 12 months. Eligible infants will receive an infusion drug (dopamine or a dextrose placebo) and a syringe drug (hydrocortisone or a normal saline placebo). Enrolled infants will be randomized to receive one of the following drug pairs: - dopamine and hydrocortisone - dopamine and normal saline - dextrose and hydrocortisone - dextrose and normal saline. In addition to the intervention above, the NRN is conducting a 6-month time-limited prospective observational study of all infants born at an NRN center between 23 and 26 weeks gestational age. All clinical decisions made for these babies will be at the discretion of the attending neonatologist/infant care team according to standard practice at each institution. Data on blood pressure management in the first 24 postnatal hours collected for each infant.
In this observational study, the NICHD Neonatal Research Network (NRN) is conducting surveillance of all infants born at NRN centers to identify all newborns who are diagnosed with early-onset sepsis (EOS) and/or meningitis. The study will: establish current hospital-based rates of EOS among term and preterm infants in the era of intrapartum antibiotic prophylaxis; monitor the organisms associated with EOS and meningitis; compare asymptomatic and symptomatic infants by gestational age and pathogen; and monitor sepsis-associated mortality rates by pathogen group.
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.
The purpose of this community-based randomized trial is to examine whether a daily antenatal and postnatal multiple micronutrient supplement given to women will enhance newborn and infant survival and health and other birth outcomes in a rural setting in northwestern Bangladesh.
