The Maternal Cytokine and Chemokine Profile of Naturally Conceived Gestations Is Mainly Preserved duringIn VitroFertilization and Egg Donation Pregna…

2015

This prospective longitudinal study aimed at comparing maternal immune response among naturally conceived (NC;n=25),in vitrofertilization (IVF;n=25), and egg donation (ED;n=25) pregnancies. The main outcome measures were, firstly, to follow up plasma levels of interleukin (IL) 1beta, IL2, IL4, IL5, IL6, IL8, IL10, IL17, interferon gamma, tumor necrosis factor-alpha (TNFα), transforming growth factor-beta (TGFβ), regulated upon activation normal T-cell expressed and secreted (RANTES), stromal cell-derived factor 1 alpha (SDF1α), and decidual granulocyte-macrophage colony-stimulating factor (GM-CSF) during the three trimesters of pregnancy during the three trimesters of pregnancy; secondly, t…

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…

Reference Values of Thyroid Hormones During the First Trimester of Pregnancy in Valencian Community (Spain) and Their Relationship with Iodine Intake

2020

Thyroid hormones require special monitoring during the first trimester of gestation. Local reference values should be applied if available, especially in iodine-deficient areas, as generalized iodine supplementation is controversial. The aim of the present study was to establish thyroid stimulating hormone (TSH) and free thyroxine (FT4) reference values in the first trimester of gestation in the Valencian community (Spain) and relate them to iodine intake. A total of 261 healthy pregnant women participated in the study. The calculated reference values were 0.128&ndash

Study on maternal, fetal and amniotic prolactin in gestational diabetic women, at term.

1982

In order to determine whether prolactin secretion was affected in diabetic pregnancy, maternal, fetal and amniotic fluid prolactin (PRL) concentrations were measured in gestational non treated diabetic women at parturition. Amniotic fluid PRL levels, though higher than those in maternal and fetal serum, were significantly lower than those of the controls (p less than 0.005); no case of respiratory distress syndrome or congenital malformation was found at birth.

Ramadan exposure and birth outcomes: a population-based study from the Netherlands.

2020

AbstractBackground:Ramadan, the Islamic month of daytime fasting, is observed by many pregnant Muslims. Although pregnant women are exempt, many prefer to fast. Previous research has shown long-term adverse effects on various health outcomes among the offspring, but evidence on effects on perinatal outcomes is mixed. This study investigates effects of Ramadan during pregnancy among Muslims in the Netherlands.Methods:Data from the Perinatal Registry of the Netherlands (Perined) on all births between 2000 and 2010 to mothers recorded as Mediterranean (i.e. of Turkish/Moroccan descent, a proxy for Muslim) (n = 139,322) or as ethnically Dutch (n = 1,481,435) were used. Ramadan exposure was defi…

One uterus bridging three generations: first live birth after mother-to-daughter uterus transplantation

2016

Objective To determine whether a uterus from the mother of a woman with absolute uterine factor infertility can be transplanted to daughter and carry a pregnancy with delivery of a healthy child. Design Part of an observational study. Setting University teaching hospital. Patient(s) Twenty eight-year-old woman with uterine agenesis, her male partner, and her 50-year-old mother. Intervention(s) In vitro fertilization with embryo cryopreservation before live donor uterus transplantation (UTx). Induction immunosuppression. Embryo transfer 12 months after UTx, pregnancy controls, delivery, and hysterectomy. Main Outcome Measure(s) Results of IVF-ET, parameters of pregnancy/birth, and surgical d…

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…

Artificial Neural Network for Predicting Iodine Deficiency in the First Trimester of Pregnancy in Healthy Women

2020

Iodine deficiency in Spain is a persisting public health problem and the prescription of potassium iodide is recommended during pregnancy. The purpose of this study was to develop an Artificial Neural Network (ANN) to predict the risk factors of iodine deficiency during pregnancy, and compare the results obtained with a logistic regression model. Two hundred forty-four healthy pregnant women were included in a descriptive and prospective study in their first trimester of pregnancy. The women enrolled were asked specifically about their use of supplements containing potassium iodide, iron, folic acid and/or multivitamins during pregnancy. The consumption of iodine-rich foods was assessed thr…

Exposure to ambient air pollution during pregnancy and preterm birth: A Spanish multicenter birth cohort study

2016

Background and objective: Preterm birth is a major determinant of infant mortality and morbidity. Air pollution has been suggested as a risk factor for preterm delivery; however, the scientific evidence on this impact remains inconsistent. We assessed the association between residential exposure to air pollution during pregnancy and preterm birth (gestational age at delivery <37 weeks) in Spain. Methods: This study was based on 2409 pregnant women participating in the INMA birth cohorts in Asturias, Gipuzkoa, Sabadell and Valencia. Ambient levels of nitrogen dioxide (NO2) and benzene were estimated for each woman's residence for each trimester and for the whole pregnancy, using temporally a…
