Studies on the kinetics and renal excretion of low and high molecular weight dextrans in preterm babies, newborns and young infants.

1977

Administration of low and high molecular weight dextrans in the initial phase of shock is no longer controversial. The special conditions in newborns, however, have been insufficiently considered in planning therapy. This investigation aimed at determining the biological half-lives of dextran 40 (Rheomacrodex®) and dextran 60 (Macrodex®) in this age group. The half-life of dextran 40 was found to be 60 min and that of dextran 60 3 h. Preterm babies and newborns excrete up to 25% less dextran 40 and 60 in 24 h than infants and adults. Normal adult values for excretion are only reached towards the end of the first year of life.

Prevalence of hypospadias in Italy according to severity, gestational age and birthweight: an epidemiological study

2009

Abstract Background Hypospadias is a congenital displacement of the urethral meatus in male newborns, being either an isolated defect at birth or a sign of sexual development disorders. The aim of this study was to assess the prevalence rate of hypospadias in different Districts of Italy, in order to make a comparison with other countries all over the world. Methods We reviewed all the newborns file records (years 2001–2004) in 15 Italian Hospitals. Results We found an overall hypospadias prevalence rate of 3.066 ± 0.99 per 1000 live births (82.48% mild hypospadias, 17.52% moderate-severe). In newborns Small for Gestational Age (birthweight th percentile) of any gestational age the prevalen…

MicroRNA-30d deficiency during preconception affects endometrial receptivity by decreasing implantation rates and impairing fetal growth.

2019

Background Maternal–embryonic crosstalk between the endometrium and the preimplantation embryo is required for normal pregnancy. Our previous results demonstrated that maternal microRNAs secreted into the endometrial fluid, specifically miR-30d, act as a transcriptomic regulator of the preimplantation embryo by the maternal intrauterine environment. Objective To investigate the reproductive and fetal effects of murine miR-30d deficiency at the maternal–embryonic interface according to the origin of its maternal or embryonic default. Study Design A miR-30d knockout murine model was used as the animal model to investigate the impact of maternal and/or embryonic origin of miR-30d deficiency on…

Residential Exposure to Outdoor Air Pollution during Pregnancy and Anthropometric Measures at Birth in a Multicenter Cohort in Spain

2011

Background: A growing body of research suggests that prenatal exposure to air pollution may be harmful to fetal development. We assessed the association between exposure to air pollution during pregnancy and anthropometric measures at birth in four areas within the Spanish Children’s Health and Environment (INMA) mother and child cohort study. Methods: Exposure to ambient nitrogen dioxide (NO2) and benzene was estimated for the residence of each woman (n = 2,337) for each trimester and for the entire pregnancy. Outcomes included birth weight, length, and head circumference. The association between residential outdoor air pollution exposure and birth outcomes was assessed with linear regress…

Exposure to video display terminals and risk of small-for-gestational-age birth

2010

In this study, the authors analyzed the association between video display terminal (VDT) use before and during the three trimesters of pregnancy and risk of small-for-gestational-age (SGA) birth in a case-control study. The cases for this study were 555 women who delivered SGA births. The controls were 1966 women who gave birth at term to healthy infants of normal weight. In terms of the length of exposure, the odds ratios (OR) of SGA birth were 1.2 for less than one hour and 1.3 for between two and 20 hours per week. For higher usage (more than 20 hours per week), the OR was 1.2 (95% CI: [Confidence Interval] 0.9-1.7). The authors conclude that this study does not show any association betw…

Multiple pregnancies and environmental exposure: An impact of air pollution on fetal growth?

2018

Introduction Multiple pregnancies display all the complications of singletons, but in highest frequencies, especially for fetal growth abnormalities. In singletons, air pollution seems to be negatively associated with fetal growth. A similar relationship in multiple pregnancies can be expected. However, multiple pregnancies are systematically excluded from the studies of the impact of air pollution on pregnancy outcomes. This study aims to analyze in a population of multiple pregnancies the relationship between fetal growth restriction (FGR), small for gestational age (SGA) and environmental chronic exposure to air pollution in moderately polluted cities. Methods All the multiple pregnancie…

Air pollution exposure during pregnancy and reduced birth size: a prospective birth cohort study in Valencia, Spain

2010

Abstract Background Maternal exposure to air pollution has been related to fetal growth in a number of recent scientific studies. The objective of this study was to assess the association between exposure to air pollution during pregnancy and anthropometric measures at birth in a cohort in Valencia, Spain. Methods Seven hundred and eighty-five pregnant women and their singleton newborns participated in the study. Exposure to ambient nitrogen dioxide (NO2) was estimated by means of land use regression. NO2 spatial estimations were adjusted to correspond to relevant pregnancy periods (whole pregnancy and trimesters) for each woman. Outcome variables were birth weight, length, and head circumf…

Small for gestational age (SGA) neonates show reduced suppressive activity of their regulatory T cells

2009

Little information exists concerning the role of fetal regulatory T cells (Tregs) during intrauterine development. We examined whether complications such as reduced birth weight or the occurrence of preterm labor were associated with deficiencies in the number or in the immunosuppressive activity of Tregs in the fetal circulation. Their total number did not change during normal or complicated pregnancy. In contrast, their level of FoxP3 expression decreased continuously with gestational age and was significantly reduced in the presence of spontaneous term, but not preterm labor. In small for gestational age (SGA) neonates, FoxP3 expression was constantly decreased when compared to age match…

2019

To evaluate the progression of Doppler abnormalities in fetuses with late-onset fetal smallness (SGA) that become growth restricted (FGR).524 Doppler examinations of the umbilical and cerebral arteries systems, belonging to 442 late-onset SGA fetuses after week 34, were studied, evaluating by means of the statistical difference with the respective abnormal centiles, the pattern of progression into abnormal Doppler values and the distribution and cumulative sum of Doppler anomalies according to the interval to delivery.Only one third (33.5%,Two thirds of late-onset fetal smallness occurs without hemodynamic changes. In half of the remaining cases an initial cerebral vasodilation defines a gr…

Maternal profile according to Mediterranean diet adherence and small for gestational age and preterm newborn outcomes

2020

AbstractObjective:The objective was to evaluate maternal Mediterranean diet (MD) pattern adherence during pregnancy and its association with small for gestational age (SGA) and preterm birth. A secondary objective of the current study was to describe the sociodemographic, lifestyle and obstetric profile of the mothers studied as well as the most relevant paternal and newborn characteristics.Design:The current study is a two-phase retrospective population-based study of maternal dietary habits during pregnancy and their effect on newborn size and prematurity. The descriptive first phase examined maternal dietary habits during pregnancy along with the maternal sociodemographic, lifestyle and …
