Phenolic compounds are among the endocrine disruptors which are widely used in daily life products. Studies in laboratory animals showed reproductive and developmental effects. In spite of widespread exposure to phenols, only few studies examined their effects on human development. This study was designed to investigate the relationship between antenatal phenol exposure and birth outcomes in a Chinese obstetric population. Four hundred ninety-six mother-infant pairs recruited from the Laizhou Wan prospective birth cohort in northern China between 2010 and 2013 were included in the study...

A common practice when analyzing multi-site epidemiological data is to include a term for 'site' to account for unmeasured effects at each location. This practice should be carefully considered when site can have complex relationships with important demographic and exposure variables. We leverage data from three longitudinal North American pregnancy cohorts to demonstrate a novel method to assess study heterogeneity and potential combinability of studies for pooled analyses in order to better understand how to consider site in analyses...

BACKGROUND: Prolonged storage of transfused red blood cells (RBCs) is associated with hemolysis in healthy adults and inflammation in animal models. We aimed to determine whether storage duration affects markers of hemolysis (e.g., serum bilirubin, iron, and non-transferrin-bound iron (NTBI)) and inflammation (e.g., interleukin (IL)-8 and monocyte chemoattractant protein (MCP)-1) in transfused very low birth weight (VLBW) infants. METHODS: Blood samples from 23 independent transfusion events were collected by heel stick before and 2-6 h after transfusion...

Ovarian cancer is one of the most common types of solid carcinoma diagnosed during pregnancy. Taxane plus a platinum derivative is a combination therapy that is predominantly used in the treatment of ovarian cancer in non-pregnant women. Pregnancy adds various complexities to a course of treatment. In pregnant patients diagnosed with cancer during the first trimester, the risks of fetal malformations and fetal loss increase following the administration of cytotoxic drugs, and this is higher with multi-agent vs...

BACKGROUND: Painful procedures are unavoidable in the medical care of preterm babies. The unpleasant experience during the neonatal period may contribute to hyperalgesia and poor neurodevelopment outcome later. Seeking effective interventions to reduce pain are strongly indicated for these very small premature babies. The aim of this study is to investigate if instilling breast milk (BM) or dextrose water into oral cavity can reduce the procedural pain of heel stick for preterm babies...

BACKGROUND: Low birth weights have been associated with a reduction in nephron number with compensatory hypertrophy of existing glomeruli. The impact of donor birth weight as an estimate of nephron number on allograft function, however, has not been examined. METHODS: We collected donor birth weight, kidney weight, and volume from 91 living kidney donor-recipient pairs before nephrectomy and after 12, 36, and 60 months. Nephron number was calculated from donor birth weight and age...

The objective of this study was to evaluate the effects of the energy restriction of gestation of adult ewes from day 45 to day 115 on lamb live performance parameters, carcass and meat traits. In experiment I, dietary energy was restricted at 70% of the metabolizable energy (ME) requirements, after which ewes were re-fed ad libitum until lambing. In experiment II, dietary energy was restricted at 60% of the ME requirements, and ewes were re-fed to ME requirements until lambing. All ewes grazed together from the end of the restriction periods to weaning...

BACKGROUND: Maternal exposures to fever and infections in pregnancy have been linked to subsequent psychiatric morbidity in the child. This study examined whether fever and common infections in pregnancy were associated with psychosis-like experiences (PLEs) in the child. METHODS: A longitudinal study of 46 184 children who participated in the 11-year follow-up of the Danish National Birth Cohort was conducted. Pregnant women were enrolled between 1996 and 2002 and information on fever, genitourinary infections, respiratory tract infection, and influenza-like illness during pregnancy was prospectively collected in two interviews during pregnancy...

This study assessed infant sleep-wake behavior at two weeks, three and six months as function of feeding method at three months (exclusively breastfed, partially breastfed, and exclusively formula fed infants). Mothers of 163 first-born, full-term, normal birth weight, healthy infants completed socio-demographic, depression, anxiety, and infant sleep-wake behavior measures. No effects were found for sleep arrangements, depression or anxiety, on feeding methods and sleep-wake behavior at three months. At two weeks exclusively breastfed infants at three months spent more hours sleeping and less hours awake during the 24-h period than partially breastfed infants...

To confirm genetic variation in low-dose effects of diethylstilbestrol (DES), two inbred strains of rats, which have been selectively bred for high- and low-avoidance learning (HAA and LAA, respectively), were used in this study. LAA rats characteristically show later sexual maturation, earlier reproductive senescence, and lower body weight as compared to HAA rats. Female neonates of each strain were daily administered DES by oral gavage at doses of 0 (vehicle only), 0.05 and 0.5μg/kg for the first 5days after birth...

PURPOSE: To investigate the ability of three-dimensional (3D) MRI placental shape and textural features to predict fetal growth restriction (FGR) and birth weight (BW) for both healthy and FGR fetuses. MATERIALS AND METHODS: We recruited two groups of pregnant volunteers between 18 and 39 weeks of gestation; 46 healthy subjects and 34 FGR. Both groups underwent fetal MR imaging on a 1.5 Tesla GE scanner using an eight-channel receiver coil. We acquired T2-weighted images on either the coronal or the axial plane to obtain MR volumes with a slice thickness of either 4 or 8 mm covering the full placenta...
