The human newborn is a reflection of the entirety of nutrients transferred from the maternal to the fetal circulation across the placenta during gestation. By extension, birth weight and newborn health depend on placental function. In this article, we quantify efficiency of the transport system in the human placenta and study its role played in the birth weight as well as the gestational age of...
OBJECTIVE To assess the association between iron status at birth and growth of preterm infants. METHODS Ninety-five premature babies (26 to 36 weeks of gestational age) born from July 2000 to May 2001 in a public hospital in Rio de Janeiro, Southeastern Brazil, were followed up for six months, corrected by gestational age. Iron measurements at birth were available for 82 mothers and 78 childr...
BACKGROUND Small-for-gestational-age in infancy is a known risk factor not only for short-term prognosis but also for several long-term outcomes, such as neurological and metabolic disorders in adulthood. Previous research has shown that severe nausea and vomiting in early pregnancy (NVP) and hyperemesis gravidarum, which is an extreme form of NVP, represent risk factors for small-for-gestation...
OBJECTIVE To determine the factors associated with mortality in a hospitalised cohort of infants in Asmara, Eritrea. DESIGN Retrospective cross-sectional review of all 2006 admissions to a specialised neonatal intensive care unit. Data on gestational age (prematurity), age at presentation, birth weight, gender, mode of delivery, Apgar score, maternal age, birth location, admission diagnosis, ...
Purpose. To investigate the association of birth parameters with refractive status in different age groups of Caucasian children. Materials and Methods. This cross-sectional study included 564 eyes of 282 children aged 4 to 17 years. All children underwent complete ophthalmologic examination. The children were divided into three groups according to their refractive status (emmetropia,myopia, an...
Immunoglobulin concentrations were determined in 64 consecutively born preterm babies at birth and serially throughout each baby's stay in the neonatal unit. No significant IgG generation was found during the first 15 weeks of life, regression analysis giving an exponential decay model. Concentrations fell to 2 g/l or less in 10 (16%) babies (gestational age 25 to 32 weeks), and were as low as ...
INTRODUCTION The pregnancy complications preeclampsia, gestational hypertension, small for gestational age infants (SGA) and pre-term birth (PTB) affect approximately 21% of all pregnancies. The Vascular Endothelial Growth Factor family (VEGF) is implicated in the pathogenesis of these complications. We aimed to evaluate the placental mRNA expression of VEGFA, PGF, FLT1 and KDR in pregnancies c...
introduction: the fetus needs a considerable amount of cholesterol for the development of tissues and organs. studies have suggested that genetic and environmental factors influence the composition of cord blood lipoproteins. in this study, we aim to assess the effect of gestational age, sex and birth weight on the cord blood lipoproteins. methods: we collected umbilical cord blood samples fr...
Received 10 June 2008 Accepted 15 October 2008 Published Online First 13 November 2008 ABSTRACT Background: Thirteen studies investigating the association between asthma during pregnancy and perinatal mortality reported generally no increased risk. Most of these studies should be interpreted with caution because they were limited in terms of statistical power. A study was therefore undertaken t...
The objective of this study was to evaluate and compare risk factor patterns in association with preeclampsia and gestational hypertension. The data were collected from The Swedish Medical Birth Register and include all nulliparas aged 34 years or less who gave birth at the University Hospital of Uppsala, Sweden, during 1987-1993. Of these 10,666 women, 4.4% developed gestational hypertension, ...
