Filter by:Studies have demonstrated that brief (5-10 min a day) passive range-of-motion exercise is beneficial for bone development in very low birth weight (VLBW) preterm infants. However, the optimal duration and frequency of exercise for bone development in preterm infants is yet unknown. The effect of exercise on the immune system was widely studied in adult and children. Exercise induces increase in IL-6, IL-10, and IL1ra. In adult even 10 minutes of flexion and extension of the wrist cause systemic increase in IL-6. The effect of physical activity on pro and anti inflammatory cytokines in preterm infant was not studied. Objectives: 1. To assess weather twice daily exercise intervention will enhance bone strength compared to once a day intervention 2. To evaluate the effect of a single exercise intervention on inflammatory mediators. Methods: Single center (Meir Medical Center), double blind, randomized control study.
VLBW infants are at risk of developing retinopathy of prematurity (ROP). In the first phase of ROP there is a down-regulation of retinal VEGF-expression because of postnatal relative hyperoxia, followed by an upregulation of VEGF mediated through retinal hypoxia, which leads to pathologic vessel formation. VEGF acts through binding to the specific receptor FLT-1, the soluble form sFLT-1 is a specific antagonist of VEGF action. Erythropoietin, given to VLBW infants to prevent anemia, may stimulate VEGF-production in neuronal cells. Currently, there are no data published about VEGF urine-levels in VLBW infants and it is not known, if urine VEGF-levels may serve as a non-invasive marker of ROP-risk. Further shall be investigated, if erythropoietin-therapy increases urine VEGF-levels and if there is a correlation with ROP-development.
The purpose of this study is to determine if sequence variations in genes involved in the development and function of vulnerable organs increases susceptibility to chronic lung disease (CLD) and other diseases affecting premature infants, such as necrotizing enterocolitis (NEC), sepsis, patent ductus arteriosus (PDA) and intraventricular hemorrhage (IVH). The study will also determine whether measurement of certain biomarkers in serum will identify infants who will develop these complications of prematurity. Previous studies from this institution and others have identified genetic variants in some genes, such as toll like receptor genes are associated with higher risk of CLD or NEC. The interaction of these variants with other gene variants that can influence the risk of these diseases remains unclear.
The purpose of this study is to compare two different treatment strategies for RDS in preterm infants > 1500 grams and evaluate whether a selective surfactant administration would reduce the need of intubation, mechanical ventilation and surfactant use.
Continuous positive airway pressure (CPAP) has been used successfully to promote extubation in the premature infant population. The two methods of CPAP to be examined are currently used by many institutions, yet no study has compared these methods to determine which is better in the population of newborns < 1500 grams (birth weight) at supporting extubation. This randomised controlled study will examine two types of CPAP: the Infant Flow System and the Bubble CPAP. This randomised controlled, single site, clinical study is to determine whether the Bubble CPAP or the Infant Flow System (IFS) CPAP is more effective at supporting the extubation in infants of birth weights < 1500 grams. Seventy-six infants will be randomised, immediately prior to extubation, to IFS or Bubble CPAP of 5 cmH2O. The primary outcome is successful extubation, defined as not reaching failure criteria for the 7 days post-extubation. Failure criteria are defined as pH < 7.25 and PCO2 > 65 mmHg or a sustained increase in FiO2 of 0.15.
The Generic Database (GDB) is a registry of very low birth weight infants born alive in NICHD Neonatal Research Network (NRN) centers. The GDB collects observational baseline data on both mothers and infants, and the therapies used and outcomes of the infants. The information collected is not specific to a disease or treatment (i.e., it is "generic"). Data are analyzed to find associations and trends between baseline information, treatments, and infant outcome, and to develop future NRN trials.
The NICHD Neonatal Research Network's Follow-Up study is a multi-center cohort in which surviving extremely low birth-weight infants born in participating network centers receive neurodevelopmental, neurosensory and functional assessments at 22-26 months corrected age (Infants born prior to July 1, 2012 were seen at 18-22 months corrected age). Data regarding pregnancy and neonatal outcome are collected prospectively. The goal is to identify potential maternal and neonatal risk factors that may affect infant neurodevelopment.
RATIONALE: Very low birth weight infants have problems maintaining normal blood sugar levels. Gluconeogenesis is the production of sugar from amino acids and fats. The best combination of amino acids, fat, and sugar to help very low birth weigh infants maintain normal blood sugar levels is not yet known. PURPOSE: Clinical trial to study how very low birth weight infants break down amino acids, fat, and sugar given by intravenous infusion, and the effect of different combinations of nutrients on the infants' ability to maintain normal blood sugar levels.
