Cerebellum and Prematurity: A Complex Interplay Between Disruptive and Dysmaturational Events.
2021
The cerebellum plays a critical regulatory role in motor coordination, cognition, behavior, language, memory, and learning, hence overseeing a multiplicity of functions. Cerebellar development begins during early embryonic development, lasting until the first postnatal years. Particularly, the greatest increase of its volume occurs during the third trimester of pregnancy, which represents a critical period for cerebellar maturation. Preterm birth and all the related prenatal and perinatal contingencies may determine both dysmaturative and lesional events, potentially involving the developing cerebellum, and contributing to the constellation of the neuropsychiatric outcomes with several impl…
Whole blood selenium content in pregnant women
1999
The selenium content in the blood of pregnant women in the Valencian Community, Spain was determined until the end of gestation in order to assess its evolution and detect possible differences in relation to the values corresponding to non-pregnant women of fertile age. A total of 158 blood samples were obtained from 137 pregnant women. Samples were classified as: (a) first; (b) second; and (c) third trimester. Selenium was determined by a flow injection hydride atomic absorption spectrometric method (Seronorm whole blood was used as a quality control check). The selenium values obtained for the three trimesters followed a Gaussian distribution. The intervals for mean found were: (a) 75.7-8…
Determinants of self-reported smoking and misclassification during pregnancy, and analysis of optimal cut-off points for urinary cotinine: a cross-se…
2013
10 p. Objectives: To estimate the prevalence and factors associated with smoking and misclassification in pregnant women from INMA (INfancia y Medio Ambiente, Environment and Childhood) project, Spain, and to assess the optimal cut-offs for urinary cotinine (UC) that best distinguish daily and occasional smokers with varying levels of second-hand smoke (SHS) exposure.-- Design: We used logistic regression models to study the relationship between sociodemographic variables and self-reported smoking and misclassification (self-reported non-smokers with UC >50 ng/ml). Receiver operating characteristic (ROC) curves were used to calculate the optimal cut-off point for discriminating smokers. The…
Tobacco use in the third trimester of pregnancy and its relationship to birth weight. A prospective study in Spain
2015
Abstract Background Few studies have been carried out in Spain examining the use of tobacco amongst expectant mothers and its effect on birth weight. Aims To observe the proportion of expectant mothers who smoke during their pregnancy, and the impact of tobacco consumption on maternal and birth weight. We also aimed to identify the trimester of pregnancy in which tobacco use produced the greatest reduction in birth weight. Methods Prospective observational study in Spain. A random sampling strategy was used to select health centres and participant women. A total of 137 individuals were enrolled in the study. Exposure to tobacco was measured through a self-reported questionnaire. Regressions…
Sleep during the third trimester of pregnancy: the role of depression and anxiety
2015
Depression has been associated with sleep disturbances in pregnancy; however, no previous research has controlled the possible confounding effect of anxiety on this association. This study aims to analyze the effect of depression on sleep during the third trimester of pregnancy controlling for anxiety. The sample was composed by 143 depressed (n = 77) and non-depressed (n = 66) pregnant women who completed measures of depression, anxiety, and sleep. Differences between groups in sleep controlling for anxiety were found. Depressed pregnant women present higher number of nocturnal awakenings and spent more hours trying falling asleep during the night and the entire 24 h period. Present findin…
Therapeutic group psychoeducation and relaxation in treating fear of childbirth
2006
The increase in the numbers of women fearing childbirth and requesting cesarean sections call for new forms of antenatal treatment.Finnish nulliparous women experiencing severe fear of childbirth (experimental group, n = 102) attended 5 group sessions with a psychologist, once together with a midwife, during the third trimester. One session was held 3 months after the delivery. Each session consisted of a discussion of fear and feelings towards the impending birth and parenthood in a psychotherapeutic atmosphere and of relaxation exercises focused on an imaginary childbirth. The results were compared with those of 85 women treated for fear of childbirth by 2 appointments with an obstetricia…
Dietary and Household Sources of Prenatal Exposure to Polybrominated Diphenyl Ethers (PBDEs) in the INMA Birth Cohort (Spain)
2016
This study looked at predictors of exposure to polybrominated diphenyl ethers (PBDEs) with a focus on dietary and household-level factors. Concentrations of BDE-47, -99, -153, and -209 and their sum (∑PBDEs) were measured in cord serum. Spanish women (n = 541) completed two semiquantitative food frequency questionnaires during the first and third trimesters of pregnancy. The daily mean intake (grams) of eggs, dairy products, meat, cereals and pasta, vegetables and pulses, fruits, shellfish and cephalopods, and fish, and the weekly mean intake (servings) of lean, large oily, other oily, and other fish from both questionnaires were averaged. Information on house size, curtains and carpets at …
Predicted and actual fetal weight throughout the last trimester.
1997
The aim of our study was to obtain, in normal pregnancies, references values of predicted and actual fetal weight for both male and female fetuses and for fetuses born to nulliparous and multiparous women between weeks 28 and 41 of gestation. Predicted fetal weight curves represented calculations of weight in the third trimester based on weight data obtained during the second trimester. These curves were obtained from 134 ultrasonograms obtained between weeks 20 and 27. Actual fetal weight curves represented the values calculated from third trimester measurements and were based on 374 ultrasonograms obtained between weeks 28 and 41. For predicted fetal weight minor differences were found be…
