Filter by:This is a prospective in vitro cell biology study of polymorphonuclear leukocyte (PMN) protein synthesis in response to PAF. PMNs from cord blood of premature human infants at risk for NEC (birth weight between 501 - 1500 grams) and PMNs from cord blood of healthy term infants will be isolated and stimulated with PAF, a biologically active phospholipid implicated in the pathogenesis of NEC. NEC, a disease of prematurity with an incidence of 10.1% of infants born weighing between 501 - 1500 grams, is associated with significant morbidity and mortality. We will compare the protein synthesis of inflammatory modulators, including Interleukin 6 Receptor alpha (IL-6R alpha) and Retinoic Acid Receptor alpha (RAR alpha) proteins to protein synthesis responses already observed in PMNs isolated from healthy adults. Furthermore, we will characterize the expression and activity of the mammalian target of rapamycin (mTOR) translational protein synthesis control pathway in PMNs isolated from preterm and term infants and compare those results with previous observations in PMNs isolated from adults. This pathway is known to regulate IL-6R alpha and RAR alpha protein expression in PMNs isolated from adults. We will also follow those premature infants at risk for NEC clinically to determine which infants develop NEC and what risk factors may be associated with NEC in this population.
The purpose of the study is to determine whether vitamin A can improve survival and facilitate recovery from sepsis and necrotizing enterocolitis in hospitalized neonates.
Meropenem is an antibiotic that is commonly used to treat serious infections. Although it is used in premature and young infants, the correct dose is not known. The purpose of this study is to determine the correct dose and the safety of meropenem for the treatment of complicated intra-abdominal infections in these young babies.
A pilot study to test the safety of use of lactulose in preterm infants and to preliminary assess the hypothesis that lactulose would support the early growth of Lactobacilli in the stools of premature infants and possibly would also improve nutritional status and decrease NEC and late-onset sepsis.
Necrotizing enterocolitis (NEC) is a severe, sometimes life-threatening inflammation of the intestine that occurs most often in premature babies. If it progresses, the wall of the intestine may perforate, spilling bacteria and stool into the abdomen. Parts or all of the intestine may die. Despite 30 years of clinical studies, the cause of NEC remains unknown. In this study, we will be conducting an independent case-control validation study to verify the diagnostic and prognostic biomarker panels, develop validated biomarkers on boisensors in preparation for prospective validation studies, and conduct independent prospective validation of biosensor based biomarker panels on clinical samples.
We investigate the efficacy of probiotics in reducing the incidence and severity of necrotizing enterocolitis (NEC) for very low birth weight (VLBW) infants.A prospective, masked, multi-center randomized control trial will be conducted level III neonatal center to evaluate the beneficial effects of probiotics for NEC among VLBW (<1500 g) infants. VLBW infants who start to feed enterally are eligible and are randomized into 2 groups after parental informed consents were obtained. Infants in the study group are fed with Infloran (Lactobacillus acidophilus and Bifidobacterium bifidus) with breast or formula milk twice daily for 6 weeks. Infants in the control group are fed with breast or formula milk alone. The clinicians caring for the infants are blinded to the group assignment. The primary outcome measurement is death or NEC (≧stage 2).
Necrotizing enterocolitis (NEC) is the most common gastrointestinal catastrophe affecting 10-15% of premature neonates of <1500 gm. NEC is a disease of the immature intestine, characterized by impaired mucosal barrier function leading to increased gut permeability. We have previously demonstrated a protective effect of probiotic administration against the development of NEC. Others have shown that prebiotics can stimulate natural production of bifidobacteria and lactobacillus in the preterm gut. We have therefore hypothesized that prophylactic administration of prebiotics would also provide protection against necrotizing enterocolitis in the premature neonate, without the potential for sepsis which has been reported on rare occasions with probiotics administration.
Excessive exposure to manganese (Mn) results in Mn deposition in the brain causing adverse neurological effects. Sick infants requiring parenteral nutrition (PN) may be at increased risk of Mn neurotoxicity because neonatal PN solutions contain high concentrations of Mn. This proposal will investigate brain deposition of Mn, a paramagnetic element, by magnetic resonance (MR) imaging in preterm and term neonates receiving Mn-supplemented PN and gestational age-matched control infants. The goals of this project are to identify neonatal populations that are at increased risk of excessive brain Mn deposition based on their gestational age, iron status, hepatic function and dietary Mn intake, and to make evidence-based recommendations for appropriate Mn supplementation and monitoring of infants receiving PN.
Manganese (Mn) is an essential metal required for normal growth and development. However, exposure to high Mn levels can be toxic to the brain. The objectives of this project are to identify neonatal and young pediatric populations that are at increased risk of excessive brain Mn deposition and altered cognitive and motor development based on their dietary parenteral Mn exposure, and to make sound and evidence-based recommendations for appropriate Mn supplementation and monitoring of infants and young children receiving parenteral nutrition (PN). Our studies are designed to test the hypotheses that, compared with unexposed age-matched controls, infants and young children receiving prolonged Mn-supplemented PN will have increased deposition of Mn in their brains and lower scores on neurodevelopmental, cognitive and psychophysiological assessments.
NEC is a serious inflammatory bowel disease, which almost only strikes infants with low birth weight and low gestational age. The morbidity and mortality rates are high, and early diagnosis and treatment is mandatory. The primary aim of the present study is to investigate the clinical use of intragastric microdialysis and whether it is able to select patients, who may benefit from either medical or surgical therapy. The aim of intraperitoneal microdialysis is to evaluate whether changes in intraperitoneal microdialysis reflect the clinical outcome after laparotomy.
