Free amino acids in preterm and term milk from mothers delivering appropriate- or small-for-gestational-age infants.
1989
Free amino acids were quantitated in human milk collected during the first month postpartum from mothers of appropriate preterm (26-32 and 33-36 wk gestation) and term (small or appropriate-for-gestational-age) infants. Glutamic acid and taurine were the most abundant amino acids in all four groups at all stages of lactation. The ratio of essential to nonessential amino acids was higher in colostrum than in mature milk although the total amino acid level of mature milk was double that of the colostrum. Nonprotein amino acids amount to approximately 40% of the free-amino acid pool in colostrum. Differences in the content and changes in free-amino acid levels during lactation among the groups…
Maternal coffee drinking in pregnancy and risk of small for gestational age birth
2005
Objective: We have analysed the association between coffee drinking before and during the three trimesters of pregnancy and risk of small for gestational age (SGA) birth. Methods: Cases were 555 women who delivered SGA births (ie <10th percentile according Italian standard). The controls included 1966 women who gave birth at term (≥37 weeks of gestation) to healthy infants of normal weight. Results: In comparison with nondrinkers, the ORs for SGA birth were 1.3 (95% confidence interval, CI, 0.9–1.9) for consumption of four or more cups of coffee/day before pregnancy, and 1.2 (95% CI 0.8–1.8), 1.2 (95% CI 0.8–1.8) and 0.9 (95% CI 0.6–1.4) for consumption of three or more cups of coffee/day d…
Assessment of ten trace elements in umbilical cord blood and maternal blood: association with birth weight
2015
Background Trace elements are an essential nutritional component for humans and inadequate tissue-concentrations may have a significant effect on fetal size. Objective To measure ten trace elements in blood samples from mothers and their newborns, and assess their association with anthropometric characteristics at birth. The effects of other factors on fetal growth, such as biologic characteristics of the infant and mother, were analysed. Methods A cross-sectional study was conducted in the Hospital general, University of Valencia, Spain. Healthy pregnant women, and their full-term infants were selected (n = 54 paired samples). Infants were grouped according to birth weight: small for gesta…
Bile salt-stimulated lipase activity in human colostrum from mothers of infants of different gestational age and birthweight.
1987
. The bile salt-stimulated lipase (BSSL) activity was measured in milk collected at 3–4 days postpartum (colostrum) from 36 mothers divided into three groups according to gestational age and birthweight of their infants. BSSL activity changed with the length of gestation. Preterm colostrum presented a mean activity significantly higher than the term groups (small-for-gestational age and appropriate-for-gestational age) which had similar values. The ratio of BSSL activity to the estimated fat content was 6.33 in colostrum of mothers who delivered preterm and 4.20 in colostrum of both groups of term mothers. These data suggest that preterm colostrum has a higher fat digesting potential than t…
Coffee drinking and risk of preterm birth
2006
Objectives: We analysed the association between coffee drinking before and during the three trimesters of pregnancy and the risk of preterm birth of babies normal for gestational age (NGA) or small for gestational age (SGA). Methods: Case-control study conducted in University clinics of North Italy. Cases were 502 women who delivered at < weeks of gestation. The controls included 1966 women who gave birth at term (≥37 weeks of gestation) to healthy infants on randomly selected days at the hospitals where cases had been identified. Results: There was inverse association for coffee consumption in the third trimester of pregnancy in SGA cases compared to NGA (heterogeneity test between OR: χ12…
Associations of maternal circulating 25-hydroxyvitamin D3 concentration with pregnancy and birth outcomes
2015
Objective To investigate the association of maternal circulating 25-hydroxyvitamin D3 [25(OH)D3] concentration with pregnancy and birth outcomes. Design Prospective cohort study. Setting Four geographical areas of Spain, 2003–2008. Population Of 2382 mother–child pairs participating in the INfancia y Medio Ambiente (INMA) Project. Methods Maternal circulating 25(OH)D3 concentration was measured in pregnancy (mean [SD] 13.5 [2.2] weeks of gestation). We tested associations of maternal 25(OH)D3 concentration with pregnancy and birth outcomes. Main outcome measures Gestational diabetes mellitus (GDM), preterm delivery, caesarean section, fetal growth restriction (FGR) and small-for-gestational…
Induced abortion and risk of small-for-gestational-age birth.
2007
Objective: To investigate the possibility of an association between previous induced abortion and subsequent birth of a small-for-gestational-age (SGA) infant. Design: Case-control study. Setting: General and university hospitals. Methods: Cases were 555 women who delivered SGA babies. Controls were 1966 women who gave birth at term (>37 weeks of gestation) to healthy infants of normal weight on randomly selected days at the hospital where cases had been identified. All women in the case and control categories were interviewed on the obstetric wards by one of a team of six interviewers. During the interviews, information was obtained regarding general socio-demographic factors, personal cha…
Proteins in preterm and term milk from mothers delivering appropriate or small-for-gestational age infants.
1986
The concentrations of total protein, secretory immunoglobulin A (IgA), lactotransferrin (LTF) and serum albumin (SA) were measured in sequential samples of colostrum, transitional and mature milk from 53 mothers divided into four groups according to gestational age and birthweight of their infants. Individual proteins were determined by single radial immunodiffusion. From the covariance analysis of data controlling for the day of lactation and the milk volume it was found that these covariables were significantly negative correlated with total protein and IgA. The concentration of LTF was also significantly negative correlated with the day but positively with the volume; whereas the contrar…
Blood cell transcript levels in 5-year-old children as potential markers of breastfeeding effects in those small for gestational age at birth
2019
BackgroundNutrition of the newborn during the early postnatal period seems to be of capital importance and there is clinical evidence showing the protective effect of breastfeeding compared with formula feeding on childhood obesity and its comorbidities. Infants born small for gestation age may be more sensitive to the type of feeding during lactation. Here, we aimed to analyze the impact of birth weight and the type of infant feeding on the expression levels in peripheral blood cells of selected candidate genes involved in energy homeostasis in 5-year-old children, to find out potential early biomarkers of metabolic programming effects during this period of metabolic plasticity.MethodsFort…
Frequency and characterization of DNA methylation defects in children born SGA
2012
Various genes located at imprinted loci and regulated by epigenetic mechanisms are involved in the control of growth and differentiation. The broad phenotypic variability of imprinting disorders suggests that individuals with inborn errors of imprinting might remain undetected among patients born small for gestational age (SGA). We evaluated quantitative DNA methylation analysis at differentially methylated regions (DMRs) of 10 imprinted loci (PLAGL1, IGF2R DMR2, GRB10, H19 DMR, IGF2, MEG3, NDN, SNRPN, NESP, NESPAS) by bisulphite pyrosequencing in 98 patients born SGA and 50 controls. For IGF2R DMR2, methylation patterns of additional 47 parent pairs and one mother (95 individuals) of patie…
