OBJECTIVE: The role of proteoglycans in the rearrangement of the extracellular matrix of the umbilical cord vein wall in pre-eclampsia is not known. Decorin, biglycan and versican are the main proteoglycans of the umbilical cord vein wall. We decided to test whether the amounts of these proteoglycans alter in pre-eclampsia. ...

Insulinlike growth factors (IGFs) exert profound effects on somatic growth and cellular proliferation of many tissues and play an essential role in bone metabolism. The aim of this study was to investigate how fetal growth and bone mineralization correlate with IGF-I and IGF-binding protein-3 (IGFBP-3) levels of newborn infants and ...

Umbilical cord blood gas and acid-base assessment are the most objective determinations of the fetal metabolic condition at the moment of birth. Moderate and severe newborn encephalopathy, respiratory complications, and composite complication scores increase with an umbilical arterial base deficit of 12-16 mmol/L. Moderate or severe newborn complications occur in ...

BACKGROUND: Umbilical cord blood (UCB) is an acceptable source of hematopoietic cells for transplantation with success being associated with the nucleated cell count (NCC), CD34+ cells, and colony-forming unit-granulocyte-macrophage (CFU-GM) content infused. A total of 1033 UCB samples with neonatal and paternal characteristics that might influence hematopoietic content were examined. ...

BACKGROUND: Periventricular-intraventricular hemorrhage, necrotizing enterocolitis, chronic lung disease and retinopathy of prematurity have been referred to as oxygen radical diseases (ORD) because they are thought to be related to excess oxidant stress relative to anti-oxidant defenses in premature infants. 8-Isoprostane is a product of lipid peroxidation that can be used ...

Thirteen infants born into the lead contaminated environment of Port Pirie, South Australia, were followed approximately monthly from birth until they were about 36 months. Blood-lead levels of infants at birth were similar to their mothers but fell rapidly during the first 35 days of life. Thereafter, infants born with ...

Mannose-binding lectin (MBL) is a component of innate immunity and thus particularly important in neonates in whom adaptive immunity is not yet completely developed. Promoter polymorphisms and structural exon-1 mutations in the MBL2 gene cause reduced or deficient MBL plasma concentrations. The aim of our study was to determine the ...

OBJECTIVE: Many previous studies of agreement in identifying placental histopathologic lesions have been based on small sample sizes, and none has examined whether individual histologic features cluster robustly together within and between observers. STUDY DESIGN: We studied 767 placental specimens from case-control studies of preterm birth and preeclampsia nested within ...
van Dijk A J - - 2006
In the limited number of studies that reported on the relation between factors affecting birth of individual piglets and acid-base balance values at birth, predominantly simple correlation coefficients have been used. The aim of the present study was to analyse the relation between factors affecting delivery of individual liveborn piglets ...

Catheterization of the umbilical artery has been a useful aid in the management of sick neonates for the past few decades. However, it is associated with various complications. Reported studies strongly suggest a significant role of intravascular catheterization in the development of aortic thrombi. Increase in thrombosis of large vessels ...

Clinical and experimental studies showing lung damage associated with biologically active neutrophil derivatives suggests the possibility that intrauterine neutrophil activation may predispose to the development of pulmonary haemorrhage in extremely low birthweight infants early after birth. To assess neutrophil functional activity in cord blood from extremely low birthweight infants who ...
Martínez-Cordero Claudia - - 2006
BACKGROUND: Low birthweight has been associated with an increased risk of obesity, insulin resistance, and diabetes in adulthood. The aim of this study was to evaluate IGF-I, adiponectin, insulin levels, and body fat in small-for-gestational-age (SGA) infants at birth. METHODS: We performed a transverse comparative study in SGA and appropriate-for-gestational-age ...

INTRODUCTION: The main limitation factor for wide use of umbilical cord blood units (UCBs) as a source of hematopoietic progenitors for transplantation is cell dose. International standard guidelines recommend 2 x 10(7)/kg as the minimal nucleated cell dose for UCB transplantation for adults and 3.7 x 10(7)/kg for children. Therefore ...

This study compared the effects of immediate (ICC) and delayed (DCC) cord clamping on very low birth weight (VLBW) infants on 2 primary variables: bronchopulmonary dysplasia (BPD) and suspected necrotizing enterocolitis (SNEC). Other outcome variables were late-onset sepsis (LOS) and intraventricular hemorrhage (IVH). This was a randomized, controlled unmasked trial ...
Ceriani Cernadas José M - - 2006
BACKGROUND: The umbilical cord is usually clamped immediately after birth. There is no sound evidence to support this approach, which might deprive the newborn of some benefits such as an increase in iron storage. OBJECTIVES: We sought to determine the effect of timing of cord clamping on neonatal venous hematocrit ...

Adiponectin is a recognized protective risk marker for cardiovascular disease in adults and is associated with an optimal lipid profile. The role of adiponectin at birth is not well understood, and its relationship with the neonatal lipid profile is unknown. Because ethnic disparities in cardiovascular risk have been attributed to ...

Omphalitis contributes to neonatal morbidity and mortality in developing countries. Umbilical cord cleansing with antiseptics might reduce infection and mortality risk, but has not been rigorously investigated. In our community-based, cluster-randomised trial, 413 communities in Sarlahi, Nepal, were randomly assigned to one of three cord-care regimens. 4934 infants were assigned ...

An infant, born at 35 weeks' gestation to a woman who sniffed petrol, had a cord blood lead level eight times the accepted limit. Treatment with oral dimercaptosuccinic acid promptly reduced his blood lead levels. To our knowledge, this is the first reported case of congenital lead poisoning secondary to ...

OBJECTIVE: Resistin is a novel hormone secreted by human adipocytes and mononuclear cells. It is expressed in the human placenta, and has been postulated to play a role in the regulation of energy metabolism during pregnancy. However, correlations between umbilical and maternal serum resistin levels and neonatal birth weight remain ...

Although cord cutting has been performed since the beginning of mankind, the timing and advantages of early versus delayed cord clamping are still controversial. Early cord clamping (within the first 30 s after birth) is usually justified for potential prevention of postpartum hemorrhage and for immediate treatment of the newborn, ...

BACKGROUND: Oxidative stress may play an important role in the pathophysiology of preeclampsia. An increase in lipid peroxidation products and a decrease in antioxidant activity in preeclamptic women have been reported in many papers. The objective of this study was to evaluate oxidative stress in infants born to preeclamptic mothers. ...

BACKGROUND: Previous studies indicate that there may be infant gender differences in cytokine expression associated with differences in neonatal morbidity. OBJECTIVE: We tested the hypothesis that umbilical cord interleukin-1 receptor antagonist (IL-1ra) correlates with infant gender and neonatal outcome in preterm infants. STUDY DESIGN: IL-1ra was measured in cord blood ...

Increased levels of unbound Free Fatty acid (FFAu) have been found in adults undergoing coronary angioplasty as a result of acute hypoxia-ischemia. We hypohesized that infants suffering from a 1-minute Apgar score of less than 5 will demonstrate elevated FFAu levels in the cord blood. One hundred ninety-nine infants between ...

Oral folic acid above certain threshold doses results in unmetabolised folic acid in serum. This raises a number of public health safety issues, principally the potential to mask pernicious anaemia; more recently the theoretical potential for high-dose folic acid to promote cancer has been highlighted. In this paper we set ...
