    Prenatal cocaine exposure (PCE) is linked to addiction and obesity vulnerability. Neural responses to stressful and appetitive cues in adolescents with PCE versus those without have been differentially linked to substance-use initiation. However, no prior studies have assessed cue-reactivity responses among PCE adolescents using a connectivity-based approach. Twenty-two PCE and 22 non-prenatally drug-exposed (NDE) age-, sex-, IQ- and BMI-matched adolescents participated in individualized guided imagery with appetitive (favorite-food), stressful and neutral-relaxing cue scripts during functional magnetic resonance imaging. Subjective favorite-food craving scores were collected before and after script exposure. A data-driven voxel-wise intrinsic connectivity distribution analysis was used to identify between-group differences and examine relationships with craving scores. A group-by-cue interaction effect identified a parietal lobe cluster where PCE versus NDE adolescents showed less connectivity during stressful and more connectivity during neutral-relaxing conditions. Follow-up seed-based connectivity analyses revealed that, among PCE adolescents, the parietal seed was positively connected to inferior parietal and sensory areas and negatively connected to corticolimbic during both stress and neutral-relaxing conditions. For NDE, greater parietal connectivity to parietal, cingulate and sensory areas and lesser parietal connectivity to medial prefrontal areas were found during stress compared to neutral-relaxing cueing. Craving scores inversely correlated with corticolimbic connectivity in PCE, but not NDE adolescents, during the favorite-food condition. Findings from this first data-driven intrinsic connectivity analysis of PCE influences on adolescent brain function indicate differences relating to PCE status and craving. These findings provide insight into the developmental impact of in utero drug exposure. Copyright © 2017 Elsevier B.V. All rights reserved.

    Risk for developing a learning disability (LD) or impaired intellectual functioning by age 7 was assessed in full-term children with prenatal cocaine exposure drawn from a cohort of 476 children born full term and enrolled prospectively at birth. Intellectual functioning was assessed using the Wechsler Intelligence Scale for Children-Third Edition (Wechsler, 1991) short form, and academic functioning was assessed using the Wechsler Individual Achievement Test (WIAT; Wechsler, 1993) Screener by examiners blind to exposure status. LDs were categorized based on ability-achievement discrepancy scores, using the regression-based predicted achievement method described in the WIAT manual. The sample in this report included 409 children (212 cocaine-exposed, 197 non-cocaine-exposed) from the birth cohort with available data. Cumulative incidence proportions and relative risk values were estimated using STATA software (Statacorp, 2003). No differences were found in the estimate of relative risk for impaired intellectual functioning (IQ below 70) between children with and without prenatal cocaine exposure (estimated relative risk = .95; 95% confidence interval [CI] = 0.65, 1.39; p = .79). The cocaine-exposed children had 2.8 times greater risk of developing a LD by age 7 than non-cocaine-exposed children (95% CI = 1.05, 7.67; p = .038; IQ >/= 70 cutoff). Results remained stable with adjustment for multiple child and caregiver covariates, suggesting that children with prenatal cocaine exposure are at increased risk for developing a learning disability by age 7 when compared to their non-cocaine-exposed peers.

    Prenatal exposure to cocaine (PCE) may alter areas of the brain dense with monoamine receptors such as the prefrontal cortex and negatively affect cognitive processes implicated in executive function (EF). This study investigated the effects of PCE on EF at 12 and 15years. EF was examined in 189 PCE and 183 non-cocaine exposed (NCE) children who were primarily African American and of low socioeconomic status. Caregivers rated their child on the Behavior Rating Inventory of Executive Function (BRIEF) at ages 12 and 15. The BRIEF includes two summary scales and eight subscales: Behavioral Regulation Index (BRI) (Inhibit, Shift, and Emotion) and Metacognition Index (MI) (Monitor, Working Memory, Plan/Organize, Organization of Materials and Task Completion). Two additional measures were included at age 15 (BRIEF Self-Report and the CANTAB Stockings of Cambridge (SOC)). Girls with PCE were perceived by caregivers to have more behavioral regulation problems at age 12 (p<0.005) and more metacognitive problems at age 12 (p<0.003) than NCE females, but there was no association for males. PCE girls improved in behavioral regulation (p<0.05) and metacognition (p<0.04) from 12 to 15years compared to NCE girls based on caregiver report. By self-report PCE was associated with problems of inhibition (p<0.006). Girls with PCE performed more poorly on number of moves to complete the SOC, requiring planning and problem solving, than NCE girls. Prenatally cocaine exposed girls were perceived by caregivers as having problems of behavioral regulation, and by self-report, inhibitory control problems. Girls with PCE also performed more poorly on a task of planning and problem solving at age 15 which corresponded to caregiver report at age 12. Early assessment and remediation of these weaknesses in girls may improve school performance and behavior associated with poor EF. Copyright © 2016. Published by Elsevier Inc.

    Preclinical studies have identified alterations in cocaine and alcohol self-administration and behavioral responses to pharmacological challenges in adolescent offspring following prenatal exposure. To date, no published human studies have evaluated the relation between prenatal cocaine exposure and postnatal adolescent cocaine use. Human studies of prenatal cocaine-exposed children have also noted an increase in behaviors previously associated with substance use/abuse in teens and young adults, specifically childhood and teen externalizing behaviors, impulsivity, and attention problems. Despite these findings, human research has not addressed prior prenatal exposure as a potential predictor of teen drug use behavior. The purpose of this study was to evaluate the relations between prenatal cocaine exposure and teen cocaine use in a prospective longitudinal cohort (n = 316) that permitted extensive control for child, parent and community risk factors. Logistic regression analyses and Structural Equation Modeling revealed that both prenatal exposure and postnatal parent/caregiver cocaine use were uniquely related to teen use of cocaine at age 14 years. Teen cocaine use was also directly predicted by teen community violence exposure and caregiver negativity, and was indirectly related to teen community drug exposure. These data provide further evidence of the importance of prenatal exposure, family and community factors in the intergenerational transmission of teen/young adult substance abuse/use. PMID:20609384

    Although correlations have been reported between maternal cocaine use and impaired attention in exposed children, interpretation of these findings is complicated by the many risk factors that differentiate cocaine-exposed children from SES-matched controls. For this reason, the present dose-response study (0, 0.5, 1.0, or 3.0 mg/kg cocaine HCl) was designed to explore the effect of prenatal cocaine exposure on visual attention in a rodent model, using an intravenous injection protocol that closely mimics the pharmacokinetic profile and physiological effects of human recreational cocaine use. In adulthood, animals were tested on an attention task in which the duration, location, and onset time of a brief visual cue varied randomly between trials. The 3.0 mg/kg exposed males committed significantly more omission errors than control males during the final 1/3 of each testing session, specifically on trials that followed an error, which implicates impaired sustained attention and increased reactivity to committing an error. During the final 1/3 of each testing session, the 0.5 and 1.0 mg/kg exposed females took longer to enter the testing alcove at trial onset, and failed to enter the alcove more frequently than control females. Because these effects were not seen in other tasks of similar duration and reinforcement density, these findings suggest an impairment of sustained attention. This inference is supported by the finding that the increase in omission errors in the final block of trials in each daily session (relative to earlier in the session) was significantly greater for the 1.0 mg/kg females than for controls, a trend also seen for the 0.5 mg/kg group. Unlike the cocaine-exposed males, who remain engaged in the task when attention is waning, the cocaine-exposed females appear to opt for another strategy; namely, refusing to participate when their ability to sustain attention is surpassed.

    Children today are exposed to cell phones early in life, and may be at the greatest risk if exposure is harmful to health. We investigated associations between cell phone exposures and headaches in children. The Danish National Birth Cohort enrolled pregnant women between 1996 and 2002. When their children reached age seven years, mothers completed a questionnaire regarding the child's health, behaviors, and exposures. We used multivariable adjusted models to relate prenatal only, postnatal only, or both prenatal and postnatal cell phone exposure to whether the child had migraines and headache-related symptoms. Our analyses included data from 52,680 children. Children with cell phone exposure had higher odds of migraines and headache-related symptoms than children with no exposure. The odds ratio for migraines was 1.30 (95% confidence interval: 1.01-1.68) and for headache-related symptoms was 1.32 (95% confidence interval: 1.23-1.40) for children with both prenatal and postnatal exposure. In this study, cell phone exposures were associated with headaches in children, but the associations may not be causal given the potential for uncontrolled confounding and misclassification in observational studies such as this. However, given the widespread use of cell phones, if a causal effect exists it would have great public health impact.

    Children born to drug abusers are exposed to teratogenic influences on intrauterine brain development and undergo postnatal withdrawal. We investigated the interplay of different domains and levels of attention functioning in 24 prenatally exposed and 25 nonexposed children who were 5 to 6 years old. Assessment included parent ratings and neuropsychological and electrophysiological methods. Exposed children had a higher prevalence of attention deficit hyperactivity symptoms, tended to have poorer performance in an attention test battery, and showed EEG alterations in P3 and N2c. Findings suggest long-term effects of prenatal drug exposure on specific domains and on different levels of attention functioning. © 2015 Michigan Association for Infant Mental Health.

    Some human behaviors, including aggression and activity level, differ on average for males and females. Here we report findings from two studies investigating possible relations between prenatal androgen and children's aggression and activity level. For study 1, aggression and activity level scores for 43 girls and 38 boys, aged 4 to 11years, with congenital adrenal hyperplasia (CAH, a genetic condition causing increased adrenal androgen production beginning prenatally) were compared to those of similarly-aged, unaffected relatives (41 girls, 31 boys). Girls with CAH scored higher on aggression than unaffected girls, d=0.69, and unaffected boys scored higher on activity level than unaffected girls, d=0.50. No other group differences were significant. For study 2, the relationship of amniotic fluid testosterone to aggression and activity level was investigated in typically-developing children (48 girls, 44 boys), aged 3 to 5years. Boys scored higher than girls on aggression, d=0.41, and activity level, d=0.50. However, amniotic fluid testosterone was not a significant predictor of aggression or activity level for either sex. The results of the two studies provide some support for an influence of prenatal androgen exposure on children's aggressive behavior, but not activity level. The within-sex variation in amniotic fluid testosterone may not be sufficient to allow reliable assessment of relations to aggression or activity level. Copyright © 2017 Elsevier Inc.

    Whether fetal neurodevelopment is disrupted by traffic-related air pollution is uncertain. Animal studies suggest that chemical and non-chemical stressors interact to impact neurodevelopment, and that this association is further modified by sex. To examine associations between prenatal traffic-related black carbon exposure, prenatal stress, and sex with children's memory and learning. Analyses included N = 258 mother-child dyads enrolled in a Boston, Massachusetts pregnancy cohort. Black carbon exposure was estimated using a validated spatiotemporal land-use regression model. Prenatal stress was measured using the Crisis in Family Systems-Revised survey of negative life events. The Wide Range Assessment of Memory and Learning (WRAML2) was administered at age 6 years; outcomes included the General Memory Index and its component indices [Verbal, Visual, and Attention Concentration]. Relationships between black carbon and WRAML2 index scores were examined using multivariable-adjusted linear regression including effect modification by stress and sex. Mothers were primarily minorities (60% Hispanic, 26% Black); 67% had ≤12 years of education. The main effect for black carbon was not significant for any WRAML2 index; however, in stratified analyses, among boys with high exposure to prenatal stress, Attention Concentration Index scores were on average 9.5 points lower for those with high compared to low prenatal black carbon exposure (P3-way interaction = 0.04). The associations between prenatal exposure to black carbon and stress with children's memory scores were stronger in boys than in girls. Studies assessing complex interactions may more fully characterize health risks and, in particular, identify vulnerable subgroups.

    Developmental plasticity models hypothesize the role of genetic and prenatal environmental influences on the development of the hypothalamic-pituitary-adrenal (HPA) axis and highlight that genes and the prenatal environment may moderate early postnatal environmental influences on HPA functioning. This article examines the interplay of genetic, prenatal and parenting influences across the first 4.5 years of life on a novel index of children's cortisol variability. Repeated measures data were obtained from 134 adoption-linked families, adopted children and both their adoptive parents and birth mothers, who participated in a longitudinal, prospective US domestic adoption study. Genetic and prenatal influences moderated associations between inconsistency in overreactive parenting from child age 9 months to 4.5 years and children's cortisol variability at 4.5 years differently for mothers and fathers. Among children whose birth mothers had high morning cortisol, adoptive fathers' inconsistent overreactive parenting predicted higher cortisol variability, whereas among children with low birth mother morning cortisol adoptive fathers' inconsistent overreactive parenting predicted lower cortisol variability. Among children who experienced high levels of prenatal risk, adoptive mothers' inconsistent overreactive parenting predicted lower cortisol variability and adoptive fathers' inconsistent overreactive parenting predicted higher cortisol variability, whereas among children who experienced low levels of prenatal risk there were no associations between inconsistent overreactive parenting and children's cortisol variability. Findings supported developmental plasticity models and uncovered novel developmental, gene × environment and prenatal × environment influences on children's cortisol functioning.

    Full Text Available Abstract Background Prenatal cocaine exposure produces attentional deficits which to persist through early childhood. Given the role of norepinephrine (NE in attentional processes, we examined the forebrain NE systems from prenatal cocaine exposed rats. Cocaine was administered during pregnancy via the clinically relevant intravenous route of administration. Specifically, we measured α2-adrenergic receptor (α2-AR density in adolescent (35-days-old rats, using [3H]RX821002 (5 nM. Results Sex-specific alterations of α2-AR were found in the hippocampus and amygdala of the cocaine-exposed animals, as well as an upregulation of α2-AR in parietal cortex. Conclusion These data suggest that prenatal cocaine exposure results in a persistent alteration in forebrain NE systems as indicated by alterations in receptor density. These neurochemical changes may underlie behavioral abnormalities observed in offspring attentional processes following prenatal exposure to cocaine.

    This study investigated infant neurobehavioral functioning during the newborn period in 334 full-term, African American neonates (187 cocaine exposed, 147 non-cocaine exposed) enrolled prospectively at birth, with documentation of drug exposure status through maternal interview and urine and meconium toxicology assays. Infants were assessed using the Brazelton Neonatal Behavioral Assessment Scale (BNBAS) during the newborn period (0-6 postnatal days). Findings from multivariate profile analyses support a consistent, modest effect of prenatal cocaine exposure on neurobehavioral functioning in full-term neonates. All of the BNBAS cluster scores, with the exception of abnormal reflexes, were similarly affected, sharing a common slope (D=-0.14; 95% CI=-0.27, -0.003; P=.046) representing a -0.14 point difference between cocaine-exposed and non-cocaine-exposed infants after controlling for prenatal exposure to alcohol, tobacco, and marijuana (ATM); maternal age, education, employment, primigravida status, and prenatal care visits; and infant sex and postnatal age in days. Fetal growth was also related to neurobehavioral functioning and, in part, mediated the relationship between cocaine exposure and the BNBAS cluster scores. Cocaine exposure during each trimester similarly influenced infant neurobehavioral profiles, with cocaine-associated deficits most pronounced in infants with exposure in all three trimesters. Results from qualitative and quantitative urine and meconium bioassay indicators further substantiated these results. Findings, while significant, represent modest effect sizes in full-term infants.

  19. Prenatal Exposure to Perfluoroalkyl Substances and Behavioral Development in Children

    Full Text Available Background: In recent years, prevalence rates of behavioral disorders in children have increased. One factor possibly implied in the etiology of behavioral disorders is exposure to perfluoroalkyl substances (PFASs. The use of PFASs is highly integrated into everyday life, and exposure is ubiquitous. Exposure to PFASs during early life may be particularly harmful, as it represents a critical time window for brain development. However, research in the area is limited, especially among preschool children. The objective of the current study was to explore the relationship between prenatal exposure to several PFASs and behavioral development at the age of 18 months. Methods: Data from the Dutch cohort LINC (Linking Maternal Nutrition to Child Health were used. Perfluorooctanesulfonic acid (PFOS and perfluorooctanoic acid (PFOA were measured in cord plasma. The total exposure of PFASs was also calculated (ΣPFASs. Behavioral development was assessed with the Child Behavior Checklist 1.5–5 (CBCL 1.5–5. The CBCL scales “Attention Deficit Hyperactivity Disorder” (ADHD and “Externalizing problems” were used for further analysis. Separate regression models were composed for each combination, in which exposure levels were classified in tertiles. Both whole population and sex-stratified analyses were performed. A family history of ADHD, the educational level, smoking or using alcohol or illicit drugs during pregnancy were considered as confounders. In total, data from 76 mother-child pairs was included. Results: No significant associations were found between prenatal PFAS exposure and ADHD scores in the whole population and in the sex-stratified analyses. With regard to externalizing behavior, a significant negative association was found between the highest levels of ΣPFAS exposure and externalizing problem behavior in the whole population, but only in the crude model. After stratifying for sex, boys in the second and third tertile of exposure

    This pilot study compared the pharmacologic treatment history and clinical outcomes observed in pediatric outpatients with psychiatric disorders exposed to drugs of abuse in utero to those of an age-matched, sex-matched and psychiatric disorder-matched, non-drug-exposed group. In this matched cohort study, medical records of children treated at an academic, child and adolescent psychiatry outpatient clinic were reviewed. Children with caregiver-reported history of prenatal drug exposure were compared with a non-drug-exposed control group being cared for by the same providers. Patients were rated with the Clinical Global Impressions-Severity scale (CGI-S) throughout treatment. The changes in pre-treatment and post-treatment CGI-S scores and the total number of medication trials were determined between groups. The drug-exposed group (n = 30) had a higher total number of lifetime medication trials compared with the non-drug-exposed group (n = 28) and were taking significantly more total medications, at their final assessment. Unlike the non-drug-exposed group, the drug-exposed group demonstrated a lack of clinical improvement. These results suggest that in utero drug-exposed children may be more treatment-refractory to or experience greater side effects from the pharmacologic treatment of psychiatric disorders than controls, although we cannot determine if early environment or drugs exposure drives these findings.

    Prenatal exposure to substances, including alcohol, opiates, and a number of illicit drugs, may have a negative impact on fetal development. Studies have shown that substance exposure can influence a child's neurodevelopment and the need for care and supportive measures. In this study, we aimed to investigate the care status and the level of supportive measures in school-aged children prenatally exposed to alcohol and other substances. This study included children aged between 6 and 14 years who were referred to Haukeland University Hospital in Norway with developmental impairment and a history of prenatal substance exposure. Participants were classified according to their main prenatal exposure to either alcohol or other substances. Information on care status and supportive measures was obtained from medical records and participants' caregivers. We also compared the use of supportive measures for children placed into foster care before and after 1 year of age. A total of 111 (87% of 128 referrals) eligible children participated in the study. Of these 111 children, 96 (86%) were in foster care, of whom 29 (30%) were placed into foster care during their first year of life and 83 out of 90 (92%) had supportive measures, including reinforced foster care and school or social support. A high proportion of the sample lived in foster care and received supportive measures. Findings may reflect an increased need of care and support in school-aged children with prenatal substance exposure, highlighting the importance of awareness among caregivers and public agencies.

    Micronutrient supplementation is often prescribed during pregnancy. The effects of prenatal iron and multimicronutrient supplementation on intellectual development in young school-aged children are less than clear. The aim of this study was to examine the long-term effects of prenatal iron plus folic acid or multiple micronutrient (including iron and folic acid) supplementation vs. folic acid supplementation on the intellectual development of young school-aged children in rural China. Young school-aged children (aged 7-10 y, n = 1744) of women who had participated in a trial of prenatal supplementation with various combinations of micronutrients and remained residents in 2 rural counties in China were followed. We measured their intellectual development by Wechsler Intelligence Scale for Children Fourth Edition (WISC-IV). The WISC-IV generated the Full-Scale Intelligence Quotient (FSIQ), Verbal Comprehension Index (VCI), Working Memory Index (WMI), Perceptual Reasoning Index (PRI), and Processing Speed Index (PSI). Multilevel analyses were used to assess the effect of prenatal micronutrient supplementation on the intellectual development of children. The mean differences in FSIQ, VCI, WMI, PRI, and PSI, respectively, were not significant between prenatal folic acid supplementation and either iron plus folic acid [-0.34 (P = 0.65), -0.06 (P = 0.95), -0.22 (P = 0.76), -0.01 (P = 0.99), and -1.26 (P = 0.11)] or multimicronutrient [-0.39 (P = 0.60), -0.64 (P = 0.48), 0.11 (P = 0.87), -0.43 (P = 0.59), and -0.34; (P = 0.65)] supplementation after adjusting for confounders. There is no evidence to suggest a different effect on intellectual development between prenatal iron plus folic acid, multimicronutrient supplementation, and prenatal folic acid supplementation in children aged 7-10 y.

    To assess the influence of mother-child interaction on children's cognitive development in a group of children prenatally exposed to methadone or buprenorphine. The study is part of a prospective longitudinal project investigating the development of children born to women in opioid maintenance therapy (OMT). The sample includes 67 children born between 2005 and 2007, 35 of which prenatally exposed to either methadone or buprenorphine and 32 non-exposed comparison children. Both groups scored within the normal range of development. However, the OMT group scored significantly lower on measures of cognitive development and mother-child interaction compared to the comparison group. Cognitive development was found to be affected by both group status, F(1,54)=5.65, p=0.02, η(2)=0.10 and mother-child interaction F(1,54)=5.26, p=0.03, η(2)=0.09. Behavioral inhibition (statue), sensorimotor function (imitating hand positions), and short-term memory (sentences) was influenced by group status while narrative memory and vocabulary were found to be more influenced by mother-child interaction. Different risk factors may influence different cognitive functions in children of women in OMT. Specifically, language-related cognitive skills may be more related to mother-child interaction while performance in higher cognitive functions requiring precise control over sensorimotor responses may be more sensitive to other factors such as prenatal OMT exposure, genetics, and/or prenatal exposure to other substances.

    Introduction of prenatal ultrasonography (USG) in fetus diagnostic caused early detection of congenital urinary tract abnormalities. Dilatation of renal pelvis, which is detected in ultrasonography from 16 week of gestational age is the most common abnormality in fetal urinary tract. The aim of the study was to assess the frequency of congenital abnormalities in urinary tract in children with prenatal suspicion of anomalies. The retrospective study included 100 children with prenatal suspicion of congenital abnormalities in urinary tract. Changes in urinary tract were detected in ultrasonography between 18-41 (mean 32,6±5,6) week of gestational age. Unilateral dilatation of urinary tract was found in 57% fetuses, bilateral dilatation in 31%, others anomalies in 12% fetuses. Ultrasonography of urinary tract was done in all children in 1-122 (mean 17,5±20,5) day of life, cystourethrography in 93% of children, renal dynamic scintygraphy in 52%, renal static scintygraphy in 16% and urography in 39% of children. Congenital urinary tract abnormalities were detected in 63% of children. Transient dilatation of renal pelvis was observed in 25% of children. We didn't find any abnormalities in 12% patients. The most common changes in urinary tract were: ureteropelvic junction obstruction (22%), vesicoureteral reflux (15%), ureterovesical junction obstruction (7%), posterior urethral valve (7%) and polycystic renal dysplasia (7%). 33% children were qualified for invasive treatment. 1. Prenatal and postnatal ultrasonography of urinary tract allows detecting congenital abnormalities of urinary tract early age of life. 2. High percentage of abnormalities in urinary tract detected in prenatal ultrasonography orders cooperation between neonatologist, urologist and nephrologist. (author)

    To prospectively evaluate the association of maternal self-esteem measured when their offspring were toddlers with the subsequent development of attention deficit hyperactivity disorder (ADHD)-like behavior in their school-age offspring and the potential modifying effects of prenatal lead exposure. We evaluated a subsample of 192 mother-child pairs from a long-running birth-cohort project that enrolled mothers in Mexico from 1994-2011. Prenatal lead exposure was assessed using cord blood lead and maternal bone lead around delivery (tibia and patella lead, measured by K-x-ray-fluorescence). When children were 2 years old, maternal self-esteem was measured using the Coopersmith Self-Esteem Inventory. When children were 7-15 years old, children's blood lead levels and ADHD symptoms were assessed, and Conners' Parent Rating Scale-Revised and Behavior Rating Inventory of Executive Function-Parent Form were used as measures of ADHD-like behavior. Adjusting for family economic status, marital status, maternal education and age, child's age and sex, and children's current blood lead levels, increased maternal self-esteem was associated with reduced child inattention behavior. Compared with those among high prenatal lead exposure (P25-P100), this association was stronger among low prenatal lead exposure groups (P1-P25, P values for the interaction effects between prenatal lead exposure and maternal self-esteem levels of self-esteem scores was associated with 0.6- to 1.3-point decrease in Conners' Parent Rating Scale-Revised and Behavior Rating Inventory of Executive Function-Parent Form T-scores among groups with low cord blood lead and patella lead (P1-P25). Children experiencing high maternal self-esteem during toddlerhood were less likely to develop inattention behavior at school age. Prenatal lead exposure may play a role in attenuating this protective effect. Copyright © 2015 Elsevier Inc. All rights reserved.

    The objective of this study was to evaluate the effects of prenatal cocaine exposure on special education at age 7 with adjustment for covariates. As part of the prospective, longitudinal, multisite study of children with prenatal cocaine exposure (Maternal Lifestyle Study), school records were reviewed for 943 children at 7 years to determine involvement in special education outcomes: (1) individualized education plan; (2) special education conditions; (3) support services; (4) special education classes; and (5) speech and language services. Logistic regression was used to examine the effect of prenatal cocaine exposure on these outcomes with environmental, maternal, and infant medical variables as covariates, as well as with and without low child IQ. Complete data for each analysis model were available for 737 to 916 children. When controlling for covariates including low child IQ, prenatal cocaine exposure had a significant effect on individualized education plan. When low child IQ was not included in the model, prenatal cocaine exposure had a significant effect on support services. Male gender, low birth weight, white race, and low child IQ also predicted individualized education plan. Low birth weight and low child IQ were significant in all models. White race was also significant in speech and language services. Other covariate effects were model specific. When included in the models, low child IQ accounted for more of the variance and changed the significance of other covariates. Prenatal cocaine exposure increased the likelihood of receiving an individualized education plan and support services, with adjustment for covariates. Low birth weight and low child IQ increased the likelihood of all outcomes. The finding that white children were more likely to get an individualized education plan and speech and language services could indicate a greater advantage in getting educational resources for this population.

    To examine whether prenatal exposure to opioid agonist medication is associated with visual selective attention and general attention problems in early childhood. Twenty-two children (mean age = 52.17 months, SD = 1.81) prenatally exposed to methadone, 9 children (mean age = 52.41 months, SD = 1.42) prenatally exposed to buprenorphine and 25 nonexposed comparison children (mean age = 51.44 months, SD = 1.31) were tested. Visual selective attention was measured with a Tobii 1750 Eye Tracker using a spatial negative priming paradigm. Attention problems were measured using the Child Behavior Checklist. The comparison group demonstrated a larger spatial negative priming effect (mean = 23.50, SD = 45.50) than the exposed group [mean = -6.84, SD = 86.39, F(1,50) = 5.91, p = 0.019, η(2) = 0.11]. No difference in reported attention problems was found [F(1,51) = 1.63, p = 0.21, η(2) = 0.03]. Neonatal abstinence syndrome and prenatal exposure to marijuana were found to predict slower saccade latencies in the exposed group (b = 54.55, SE = 23.56, p = 0.03 and b = 88.86, SE = 32.07, p = 0.01, respectively). Although exposed children did not appear to have attention deficits in daily life, lower performance on the SNP task indicates subtle alteration in the attention system. © 2014 S. Karger AG, Basel.

    Exposure to perfluoroalkyl substances (PFASs) may impact children's neurodevelopment. To examine the association of prenatal and early childhood serum PFAS concentrations with children's reading skills at ages 5 and 8years. We used data from 167 mother-child pairs recruited during pregnancy (2003-2006) in Cincinnati, OH, quantified prenatal serum PFAS concentrations at 16±3weeks of gestation and childhood sera at ages 3 and 8years. We assessed children's reading skills using Woodcock-Johnson Tests of Achievement III at age 5years and Wide Range Achievement Test-4 at age 8years. We used general linear regression to quantify the covariate-adjusted associations between natural log-transformed PFAS concentrations and reading skills, and used multiple informant model to identify the potential windows of susceptibility. Median serum PFASs concentrations were PFOS>PFOA>PFHxS>PFNA in prenatal, 3-year, and 8-year children. The covariate-adjusted general linear regression identified positive associations between serum PFOA, PFOS and PFNA concentrations and children's reading scores at ages 5 and 8years, but no association between any PFHxS concentration and reading skills. The multiple informant model showed: a) Prenatal PFOA was positively associated with higher children's scores in Reading Composite (β: 4.0, 95% CI: 0.6, 7.4 per a natural log unit increase in exposure) and Sentence Comprehension (β: 4.2, 95% CI: 0.5, 8.0) at age 8years; b) 3-year PFOA was positively associated with higher children's scores in Brief Reading (β: 7.3, 95% CI: 0.9, 13.8), Letter Word Identification (β: 6.6, 95% CI: 1.1, 12.0), and Passage Comprehension (β: 5.9, 95% CI: 1.5, 10.2) at age 5years; c) 8-year PFOA was positively associated with higher children's Word Reading scores (β: 5.8, 95% CI: 0.8, 10.7) at age 8years. Prenatal PFOS and PFNA were positively associated with children's reading abilities at age 5years, but not at age 8years; 3-year PFOS and PFNA were positively associated

    Full Text Available The development of effective methods for the analysis and prognosis of the survival of newborns with prenatally diagnosed congenital malformations of the cardiovascular system are the urgent task of modern medicine. Objective – a neural network model for predicting the survival of children with prenatally diagnosed congenital malformations of the cardiovascular system was developed. Materials and methods. To create the artificial neural networks, the method of constructing multifactor mathematical prediction models in the software package Statistica 6.0 was used. The significance level of the factors influencing the survival of children with prenatally diagnosed congenital malformations of the cardiovascular system was determined using Wald statistics. When checking statistical hypotheses, the critical level of significance was assumed to be 0,05. Results. A neural network model for the determination of the probability of survival of a child with prenatally diagnosed congenital malformations of the cardiovascular system, which has a high prognostic ability of 0,88, sensitivity of the model was 77,6 %, specificity 86,4 %. The value of prognostic survival probability is in the range from 0 to 100 %. With an indicator value of more than 80 %, the probability of survival of a child with prenatally diagnosed congenital malformations of the cardiovascular system is estimated as high, ranging from 20 % to 80 % – as an average and less than 20 % – as low. Conclusion. In the algorithm for predicting the survival of children with prenatally diagnosed congenital malformations of the cardiovascular system it is necessary to include a combination with other pathology of cardiovascular system, with other organs and systems, with chromosomal abnormalities, with microdeletion and monogenic syndromes.

    We aimed to examine whether exposure to prenatal stress following maternal bereavement is associated with an increased risk of febrile seizures. In a longitudinal population-based cohort study, we followed 1,431,175 children born in Denmark. A total of 34,777 children were born to women who lost...... a close relative during pregnancy or within 1 year before the pregnancy and they were included in the exposed group. The exposed children had a risk of febrile seizures similar to that of the unexposed children (hazard ratio (HR) 1.00, 95% CI 0.94-1.06). The HRs did not differ according to the nature...... or timing of bereavement. Our data do not suggest any causal link between exposure to prenatal stress and febrile seizures in childhood....

    Background The long-term neurotoxicity risks caused by prenatal exposures to pesticides are unclear, but a previous pilot study of Ecuadorian school children suggested that blood pressure and visuospatial processing may be vulnerable. Objectives In northern Ecuador, where floriculture is intensive and relies on female employment, we carried out an intensive cross-sectional study to assess children’s neurobehavioral functions at 6–8 years of age. Methods We examined all 87 children attending two grades in the local public school with an expanded battery of neurobehavioral tests. Information on pesticide exposure during the index pregnancy was obtained from maternal interview. The children’s current pesticide exposure was assessed from the urinary excretion of organophosphate metabolites and erythrocyte acetylcholine esterase activity. Results Of 84 eligible participants, 35 were exposed to pesticides during pregnancy via maternal occupational exposure, and 23 had indirect exposure from paternal work. Twenty-two children had detectable current exposure irrespective of their prenatal exposure status. Only children with prenatal exposure from maternal greenhouse work showed consistent deficits after covariate adjustment, which included stunting and socioeconomic variables. Exposure-related deficits were the strongest for motor speed (Finger Tapping Task), motor coordination (Santa Ana Form Board), visuospatial performance (Stanford-Binet Copying Test), and visual memory (Stanford-Binet Copying Recall Test). These associations corresponded to a developmental delay of 1.5–2 years. Prenatal pesticide exposure was also significantly associated with an average increase of 3.6 mmHg in systolic blood pressure and a slight decrease in body mass index of 1.1 kg/m2. Inclusion of the pilot data strengthened these results. Conclusions These findings support the notion that prenatal exposure to pesticides—at levels not producing adverse health outcomes in the mother

    Psychological stress during pregnancy increases the risk of childhood wheeze and asthma. However, the transmitting mechanisms remain largely unknown. Since epigenetic alterations have emerged as a link between perturbations in the prenatal environment and an increased disease risk we used whole genome bisulfite sequencing (WGBS) to analyze changes in DNA methylation in mothers and their children related to prenatal psychosocial stress and assessed its role in the development of wheeze in the child. We evaluated genomic regions altered in their methylation level due to maternal stress based of WGBS data of 10 mother-child-pairs. These data were complemented by longitudinal targeted methylation and transcriptional analyses in children from our prospective mother-child cohort LINA for whom maternal stress and wheezing information was available (n = 443). High maternal stress was associated with an increased risk for persistent wheezing in the child until the age of 5. Both mothers and children showed genome-wide alterations in DNA-methylation specifically in enhancer elements. Deregulated neuroendocrine and neurotransmitter receptor interactions were observed in stressed mothers and their children. In children but not in mothers, calcium- and Wnt-signaling required for lung maturation in the prenatal period were epigenetically deregulated and could be linked with wheezing later in children's life.

    Heavy prenatal alcohol exposure is associated with impaired school functioning. Spelling performance has not been comprehensively evaluated. We examined whether children with heavy prenatal alcohol exposure demonstrate deficits in spelling and related abilities, including reading, and tested whether there are unique underlying mechanisms for observed deficits in this population. Ninety-six school-age children made up 2 groups: children with heavy prenatal alcohol exposure (AE, n = 49) and control children (CON, n = 47). Children completed select subtests from the Wechsler Individual Achievement Test-Second Edition and the NEPSY-II. Group differences and relations between spelling and theoretically related cognitive variables were evaluated using multivariate analysis of variance and Pearson correlations. Hierarchical regression analyses were used to assess contributions of group membership and cognitive variables to spelling performance. The specificity of these deficits and underlying mechanisms was tested by examining the relations between reading ability, group membership, and cognitive variables. Groups differed significantly on all variables. Group membership and phonological processing significantly contributed to spelling performance, whereas for reading, group membership and all cognitive variables contributed significantly. For both reading and spelling, group × working memory interactions revealed that working memory contributed independently only for alcohol-exposed children. Alcohol-exposed children demonstrated a unique pattern of spelling deficits. The relation of working memory to spelling and reading was specific to the AE group, suggesting that if prenatal alcohol exposure is known or suspected, working memory ability should be considered in the development and implementation of explicit instruction.

    To evaluate the effect of prenatal acetaminophen exposure on the future development of attention deficit/hyperactivity disorder (ADHD) in children. Literature searches of MEDLINE (1975 to June 2015), International Pharmaceutical Abstracts (1975 to June 2015), and Cochrane Database (publications through June 2015) for prospective clinical trials assessing the relationship of prenatal acetaminophen exposure and the development of attention deficit disorders or hyperactivity. Studies comparing self-reported maternal acetaminophen use during pregnancy to development of ADHD or ADHD-like behaviors in offspring between the ages of 3 and 12 years. Four studies examining the effects of prenatal acetaminophen exposure on subsequent ADHD behaviors were identified. Of these, one early study found no link to ADHD behaviors while the other studies found statistically significant correlations with the most prominent being a study finding a higher risk for using ADHD medications (hazard ratio = 1.29; 95% CI, 1.15-1.44) or having ADHD-like behaviors at age 7 years as determined by the Strengths and Difficulties Questionnaire (risk ratio = 1.13; 95% CI, 1.01-1.27) in children whose mothers used acetaminophen during pregnancy. While there does appear to be a mild correlation between prenatal acetaminophen use and the development of ADHD symptoms in children, current data do not provide sufficient evidence that prenatal acetaminophen exposure leads to development of ADHD symptoms late in life. Acetaminophen is a preferred option for pain management during pregnancy when compared with other medications such as nonsteroidal anti-inflammatory drugs or opioids for pyretic or pain relief. © The Author(s) 2015.

    Temporal- and sex-specific effects of perinatal stress have not been examined for childhood asthma. We examined associations between prenatal and/or postnatal stress and children's asthma (n = 765) and effect modification by sex in a prospective cohort study. Maternal negative life events were ascertained prenatally and postpartum. Negative life event scores were categorized as 0, 1 to 2, 3 to 4, or 5 or greater to assess exposure-response relationships. We examined effects of prenatal and postnatal stress on children's asthma by age 6 years, modeling each as independent predictors, mutually adjusting for prenatal and postnatal stress, and finally considering interactions between prenatal and postnatal stress. Effect modification by sex was examined in stratified analyses and by fitting interaction terms. When considering stress in each period independently, among boys, a dose-response relationship was evident for each level increase on the ordinal scale prenatally (odds ratio [OR], 1.38; 95% CI, 1.06-1.79; P value for trend = .03) and postnatally (OR, 1.53; 95% CI, 1.16-2.01; P value for trend = .001); among girls, only the postnatal trend was significant (OR, 1.60; 95% CI, 1.14-2.22; P value for trend = .005). Higher stress in both the prenatal and postnatal periods was associated with increased odds of receiving a diagnosis of asthma in girls (OR, 1.37; 95% CI, 0.98-1.91; Pinteraction = .07) but not boys (OR, 1.08; 95% CI, 0.82-1.42; Pinteraction = .61). Although boys were more vulnerable to stress during the prenatal period, girls were more affected by postnatal stress and cumulative stress across both periods in relation to asthma. Understanding sex and temporal differences in response to early-life stress might provide unique insight into the cause and natural history of asthma.

    Research suggests that genetic, prenatal, endocrine, and parenting influences across development individually contribute to internalizing and externalizing problems in children. The present study tests the combined contributions of genetic risk for psychopathology, prenatal environments (maternal drug use and internalizing symptoms), child cortisol at age 4.5 years, and overreactive parenting influences across childhood on 6-year-old children's internalizing and externalizing problems. We used data from an adoption design that included 361 domestically adopted children and their biological and adopted parents prospectively followed from birth. Only parenting influences contributed (independently) to externalizing problems. However, genetic influences were indirectly associated with internalizing problems (through increased prenatal risk and subsequent morning cortisol), and parenting factors were both directly and indirectly associated with internalizing problems (through morning cortisol). Results suggest that prenatal maternal drug use/symptoms and children's morning cortisol levels are mechanisms of genetic and environmental influences on internalizing problems, but not externalizing problems, in childhood.

    This study evaluated how enrollment in special education services in 11-year-old children relates to prenatal cocaine exposure (PCE), psychopathology, and other risk factors. Participants were 498 children enrolled in The Maternal Lifestyle Study, a prospective, longitudinal, multisite study examining outcomes of children with PCE. Logistic regression was used to examine the effect of PCE and psychopathology on enrollment in an individualized education plan (IEP; a designation specific to children with special education needs), with environmental, maternal, and infant medical variables as covariates. PCE, an interaction of PCE and oppositional defiant disorder, child attention-deficit hyperactivity disorder, parent-reported internalizing behaviors, and teacher-reported externalizing behaviors, predicted enrollment in an IEP. Other statistically significant variables in the model were male gender, low birth weight, being small for gestational age, white race, caregiver change, low socioeconomic status, low child intelligence quotient, caregiver depression, and prenatal marijuana exposure. PCE increased the likelihood of receiving an IEP with adjustment for covariates. Psychopathology also predicted this special education outcome, in combination with and independent of prenatal cocaine exposure.

    Full Text Available Emerging evidence indicate that maternal prenatal stress (MPS can result in a range of long-term adverse effects in the offspring. The underlying mechanism of MPS is not fully understood. However, its complexity is emphasized by the number of purportedly involved pathways namely, placental deregulated metabolism of maternal steroids, impaired maturation of fetal HPA axis, imbalanced efflux of commensal bacteria across the placenta, and skewed immune development toward Th2. Fetal programming probably exerts a pivotal role in the end result of the above pathways through the modulation of gene expression. In this review, we highlight the current knowledge from epidemiological and experimental studies regarding the effects of MPS on asthma development in the offspring.

    Prenatal maternal obesity has been linked to adverse childhood neuropsychiatric outcomes, including increased symptoms of attention deficit hyperactivity disorder (ADHD), internalizing and externalizing problems, affective disorders and neurodevelopmental problems but few studies have studied neuropsychiatric outcomes among offspring born to very severely obese women or assessed potential familial confounding by maternal psychological distress. We evaluated neuropsychiatric symptoms in 112 children aged 3-5 years whose mothers had participated in a longitudinal study of obesity in pregnancy (50 very severe obesity, BMI ⩾40 kg/m2, obese class III and 62 lean, BMI 18.5-25 kg/m2). The mothers completed the Conners' Hyperactivity Scale, Early Symptomatic Syndrome Eliciting Neurodevelopmental Clinical Examination Questionnaire (ESSENCE-Q), Child's Sleep Habits Questionnaire (CSHQ), Strengths and Difficulties Questionnaire (SDQ), and Child Behavior Checklist (CBCL) to assess child neuropsychiatric symptoms. Covariates included child's sex, age, birthweight, gestational age, socioeconomic deprivation levels, maternal age, parity, smoking status during pregnancy, gestational diabetes and maternal concurrent symptoms of anxiety and depression assessed using State Anxiety of Spielberger State-Trait Anxiety Index (STAI) and General Health Questionnaire (GHQ), respectively. Children exposed to prenatal maternal very severe obesity had significantly higher scores in the Conners' Hyperactivity Scale; ESSENCE-Q; total sleep problems in CSHQ; hyperactivity, conduct problems and total difficulties scales of the SDQ; higher externalizing and total problems, anxious/depressed, aggressive behaviour and other problem syndrome scores and higher DSM-oriented affective, anxiety and ADHD problems in CBCL. Prenatal maternal very severe obesity remained a significant predictor of child neuropsychiatric problems across multiple scales independent of demographic factors, prenatal factors and

    To study the oral health and dental neglect of prenatally buprenorphine-exposed 3-year-old children. The study consisted of 51 children who as newborns tested positive for buprenorphine in a urine screen. The control group comprised 68 children previously unexposed to narcotics. The dentist examined the children and interviewed their guardians. Buprenorphine-exposed children exhibited significantly more early childhood caries than did the control group. Caries indices, the number of decayed, missing and filled teeth or tooth surfaces and decayed teeth were greater in the buprenorphine-exposed children than the control children (p = 0.004, p = 0.004, p = 0.001, respectively). In the buprenorphine group, more children showed visible plaque (p = 0.003) and fewer children were caries-free (p = 0.009) than in the control group. The control children's teeth were also brushed more often than the buprenorphine-exposed children's teeth (p = 0.001) and the parents were more involved in their children's tooth brushing than were those in the buprenorphine-exposed group (p = 0.035). More caries and dental neglect were found in buprenorphine-exposed children than in controls. These findings highlight the importance of routine dental appointments, caries screening and preventive care for children in substance-abusing families.

    Full Text Available Introduction. The association of prenatal growth with nutritional status, metabolic syndrome (MS, and insulin resistance (IR was studied in school-age children. Methods. A retrospective cohort study was designed linking present data of children with perinatal records. 3325 subjects were enrolled. Anthropometry, blood pressure (BP, and pubertal status were assessed. Blood lipids, glucose, and insulin were measured. Linear associations were assessed using the Cochran-Armitage test. Odds ratios and nonlinear associations were computed. Results. 3290 children (52% females, mean age of 11.4 ± 1 years were analyzed. Prevalence of obesity, stunting, MS, and IR was 16.0%, 3.6%, 7.3%, and 25.5%, respectively. The strongest positive association was between birth weight (BW and obesity (OR 2.97 (95% CI 2.01–4.40 at BW ≥ 4,000 g compared to BW 2,500–2,999. The strongest inverse association was between birth length (BL and stunting (OR 8.70 (95% CI 3.66–20.67 at BL < 48 cm compared to BL 52-53 cm. A U-shaped association between BL and BP ≥ 90th percentile was observed. Significant ORs were also found for MS and IR. Adjustments for present fat mass increased or maintained the most prenatal growth influences. Conclusions. Prenatal growth influences MS, IR, and nutritional status. Prenatal growth was more important than present body composition in determining these outcomes.

    Prenatal exposure to chlorpyrifos (CPF), an organophosphate insecticide, is associated with neurobehavioral deficits in humans and animal models. We investigated associations between CPF exposure and brain morphology using magnetic resonance imaging in 40 children, 5.9-11.2 y, selected from a nonclinical, representative community-based cohort. Twenty high-exposure children (upper tertile of CPF concentrations in umbilical cord blood) were compared with 20 low-exposure children on cortical surface features; all participants had minimal prenatal exposure to environmental tobacco smoke and polycyclic aromatic hydrocarbons. High CPF exposure was associated with enlargement of superior temporal, posterior middle temporal, and inferior postcentral gyri bilaterally, and enlarged superior frontal gyrus, gyrus rectus, cuneus, and precuneus along the mesial wall of the right hemisphere. Group differences were derived from exposure effects on underlying white matter. A significant exposure × IQ interaction was derived from CPF disruption of normal IQ associations with surface measures in low-exposure children. In preliminary analyses, high-exposure children did not show expected sex differences in the right inferior parietal lobule and superior marginal gyrus, and displayed reversal of sex differences in the right mesial superior frontal gyrus, consistent with disruption by CPF of normal behavioral sexual dimorphisms reported in animal models. High-exposure children also showed frontal and parietal cortical thinning, and an inverse dose-response relationship between CPF and cortical thickness. This study reports significant associations of prenatal exposure to a widely used environmental neurotoxicant, at standard use levels, with structural changes in the developing human brain.

    Researchers are increasingly considering the importance of motor functioning of children with fetal alcohol spectrum disorder (FASD). The purpose of this study was to assess the motor development of young children with fetal alcohol syndrome (FAS) to determine the presence and degree of delay in their motor skills and to compare their motor development with that of matched children without FAS. The motor development of 14 children ages 20 to 68 months identified with FAS was assessed using the Vineland Adaptive Behavior Scales (VABS). In addition, 2 comparison groups were utilized. Eleven of the children with FAS were matched for chronological age, gender, ethnicity, and communication age to: (1) 11 children with prenatal alcohol exposure who did not have FAS and (2) 11 matched children without any reported prenatal alcohol exposure. The motor scores on the VABS were compared among the 3 groups. Most of the young children with FAS in this study showed clinically important delays in their motor development as measured on the VABS Motor Domain, and their fine motor skills were significantly more delayed than their gross motor skills. In the group comparisons, the young children with FAS had significantly lower Motor Domain standard (MotorSS) scores than the children not exposed to alcohol prenatally. They also had significantly lower Fine Motor Developmental Quotients than the children in both the other groups. No significant group differences were found in gross motor scores. For MotorSS scores and Fine Motor Developmental Quotients, the means and standard errors indicated a continuum in the scores from FAS to prenatal alcohol exposure to nonexposure. These findings strongly suggest that all young children with FAS should receive complete developmental evaluations that include assessment of their motor functioning, to identify problem areas and provide access to developmental intervention programs that target deficit areas such as fine motor skills.

    The investigation involved 50 children aged median 6 years and 6 months. The group was selected in view of the critical period for occurrence of radiation-related deviations in mental development (8-15 gestation weeks) and the period of maximum irradiation during the Chernobyl accident. Assessment of the individual exposure and analysis of possible impacts from non-radiation risk factors were based on guided parental history reports. The dose of accidental irradiation was determined using the radiological data for the country. A Bulgarian standardization of the Wechsler Intelligence Scale for Children (WISC-R) was used. The procedure includes 5 verbal and 5 nonverbal subtests. Results were compared with those from a countrywide control group of children (including a large city, a small town, a village). The analysis indicated higher mean IQ scores in the investigated children. The children were additionally studied by original tests for attention and gnosis-praxis functions using tactile and visual modalities. The tests included intra- and transmodal versions, bilateral simultaneous presentation of stimuli with verbal and nonverbal characteristics in applying analytical and global strategies. Comparisons were made with results for children in the same age range, who had been studied prior to the Chernobyl accident. The evidence surprisingly varied, taking into account the small size of the investigation group. A longitudinal follow-up of this population thus appears to be appropriate. (author)

    Prenatal maternal depression has been associated with multiple problems in offspring involving affect, cognition, and neuroendocrine functioning. This suggests that prenatal depression influences neurodevelopment. However, the underlying neurodevelopmental mechanism remains unclear. We prospectively assessed whether maternal depressive symptoms during pregnancy and at the child's age 3 years are related to white matter microstructure in 690 children. The association of paternal depressive symptoms with childhood white matter microstructure was assessed to evaluate genetic or familial confounding. Parental depressive symptoms were measured using the Brief Symptom Inventory. In children aged 6-9 years, we used diffusion tensor imaging to assess white matter microstructure characteristics including fractional anisotropy (FA) and mean diffusivity (MD). Exposure to maternal depressive symptoms during pregnancy was associated with higher MD in the uncinate fasciculus and to lower FA and higher MD in the cingulum bundle. No associations of maternal depressive symptoms at the child's age of 3 years with white matter characteristics were observed. Paternal depressive symptoms also showed a trend toward significance for a lower FA in the cingulum bundle. Prenatal maternal depressive symptoms were associated with higher MD in the uncinate fasciculus and the cingulum bundle. These structures are part of the limbic system, which is involved in motivation, emotion, learning, and memory. As paternal depressive symptoms were also related to lower FA in the cingulum, the observed effect may partly reflect a genetic predisposition and shared environmental family factors and to a lesser extent a specific intrauterine effect. © 2018 Wiley Periodicals, Inc.

    BACKGROUND: Emerging evidence suggests that prenatal or early-life exposures to environmental contaminants may contribute to an increased risk of asthma and allergies in children. We aimed to the explore associations of prenatal exposures to a large set of environmental chemical contaminants...... asthma, eczema, and wheeze. We applied principal components analysis (PCA) to sixteen contaminants in maternal serum sampled during pregnancy, including perfluoroalkyl substances (PFASs), metabolites of diethylhexyl (DEHP) and diisononyl (DiNP) phthalates, PCB-153, and p,p'-DDE. Scores of five principal...... components (PCs) explaining 70% of the variance were included in multiple logistic regression models. RESULTS: In a meta-analysis that included both populations, the PC2 score, reflecting exposure to DiNP, was negatively associated with current eczema (OR 0.71, 95% CI 0.52-0.96). Other associations were...

    Polybrominated diphenyl ethers (PBDEs) are associated with impaired visual spatial abilities in toxicological studies, but no epidemiologic study has investigated PBDEs and visual spatial abilities in children. The Health Outcomes and Measures of the Environment Study, a prospective birth cohort (2003–2006, Cincinnati, OH), was used to examine prenatal and childhood PBDEs and visual spatial abilities in 199 children. PBDEs were measured at 16±3 weeks gestation and at 1, 2, 3, 5, and 8 years using gas chromatography/isotope dilution high-resolution mass spectrometry. We used the Virtual Morris Water Maze to measure visual spatial abilities at 8 years. In covariate-adjusted models, 10-fold increases in BDE-47, −99, and −100 at 5 years were associated with shorter completion times by 5.2 s (95% Confidence Interval [CI] −9.3, −1.1), 4.5 s (95% CI −8.1, −0.9), and 4.7 s (95% CI −9.0, −0.3), respectively. However, children with higher BDE-153 at 3 years had longer completion times (β=5.4 s, 95% CI −0.3, 11.1). Prenatal PBDEs were associated with improved visual spatial memory retention, with children spending a higher percentage of their search path in the correct quadrant. Child sex modified some associations between PBDEs and visual spatial learning. Longer path lengths were observed among males with increased BDE-47 at 2 and 3 years, while females had shorter paths. In conclusion, prenatal and postnatal BDE-28, −47, −99, and −100 at 5 and 8 years were associated with improved visual spatial abilities, whereas a pattern of impairments in visual spatial learning was noted with early childhood BDE-153 concentrations. - Highlights: • The VMWM test was used to assess visual spatial abilities in children at 8 years. • BDE-153 at 3 years was adversely associated with visual spatial learning. • BDE-47, −99, and −100 at 5 years was associated with better visual spatial learning. • Prenatal PBDEs were associated with improved visual

    Full Text Available Number processing is a cognitive domain particularly sensitive to prenatal alcohol exposure, which relies on intact parietal functioning. Alcohol-related alterations in brain activation have been found in the parietal lobe during symbolic number processing. However, the effects of prenatal alcohol exposure on the neural correlates of non-symbolic number comparison and the numerical distance effect have not been investigated. Using functional magnetic resonance imaging (fMRI, we examined differences in brain activation associated with prenatal alcohol exposure in five parietal regions involved in number processing during a non-symbolic number comparison task with varying degrees of difficulty. fMRI results are presented for 27 Cape Colored children (6 fetal alcohol syndome (FAS/partial FAS, 5 heavily exposed (HE non-sydromal, 16 controls; mean age ± SD = 11.7 ± 1.1 years. Fetal alcohol exposure was assessed by interviewing mothers using a timeline follow-back approach. Separate subject analyses were performed in each of five regions of interest, bilateral horizontal intraparietal sulci (IPS, bilateral posterior superior parietal lobules (PSPL, and left angular gyrus (left AG, using the general linear model with predictors for number comparison and difficulty level. Mean percent signal change for each predictor was extracted for each subject for each region to examine group differences and associations with continuous measures of alcohol exposure. Although groups did not differ in performance, controls activated the right PSPL more during non-symbolic number comparison than exposed children, but this was not significant after controlling for maternal smoking, and the right IPS more than children with fetal alcohol syndrome (FAS or partial FAS. More heavily exposed children recruited the left AG to a greater extent as task difficulty increased, possibly to compensate, in part, for impairments in function in the PSPL and IPS. Notably, in non

    The reproductive safety of selective reuptake inhibitor (SRI) antidepressants needs to be established to provide optimal control of maternal depression while protecting the fetus. To define a child's neurodevelopment following prenatal exposure to SRIs and to account for genetic and environmental confounders in a sibling design using the Toronto Motherisk prospective database. Intelligence and behavior of siblings prenatally exposed and unexposed to SRIs were assessed by using the Wechsler Preschool and Primary Scale of Intelligence-Third Edition, Child Behavior Checklist, and Conners Parent Rating Scale-Revised and subsequently compared. Mothers, diagnosed with depression using DSM-IV, were assessed for intelligence quotient (IQ) and for severity of depressive symptoms with the Center for Epidemiologic Studies Depression scale. Prenatal drug doses and durations of exposure, child's age, child's sex, birth order, severity of maternal depression symptoms, and Full Scale IQ, the primary outcome measure, of both the mother and the child were considered in the analyses. Forty-five sibling pairs (ages 3 years to 6 years 11 months, prenatally exposed and unexposed to SRIs) did not differ in their mean ± SD Full Scale IQs (103 ± 13 vs 106 ± 12; P = .30; 95% CI, -7.06 to 2.21) or rates of problematic behaviors. Significant predictor of children's intelligence was maternal IQ (P = .043, β = 0.306). Severity of maternal depression was a significant predictor of Child Behavior Checklist Internalizing (P = .019, β = 0.366), Externalizing (P = .003, β = 0.457), and Total scores (P = .001, β = 0.494). Drug doses and durations of exposure during pregnancy did not predict any outcomes of interest in the exposed siblings. SRI antidepressants were not found to be neurotoxic. Maternal depression may risk the child's future psychopathology. The sibling design in behavioral teratology aids in separating the effects of maternal depression from those of SRIs, providing stronger

    The goal of this study was to assess the effect of prenatal maternal cigarette smoking on children's BMI z-score trajectories, and to evaluate whether small-for-gestational-age (SGA) acts as a potential mediator between prenatal maternal cigarette smoking and child's BMI z-score at 4 years of age. Group-based trajectory modeling (GBTM) methods were employed to describe and classify developmental BMI z-score trajectories (the outcome of interest) in children from 9 months to 4 years of age (n = 5221) in the Early Childhood Longitudinal Study, Birth Cohort (ECLS-B) study (2001-2005). Further analysis examined whether the identified BMI z-score trajectories varied with the exposure, prenatal maternal cigarette smoking. Mediation analyses were utilized to examine whether being SGA (binary measure) acted as a potential mediator in the relationship between prenatal maternal cigarette smoking and BMI z-score among 4-year-old children. Using GBTM, two BMI z-score trajectory groups were identified: normal BMI z-score (57.8%); and high BMI z-score (42.2%). Children of mothers who smoked cigarettes during pregnancy were 2.1 times (RR 95% CI: 1.1-4.0, P value = 0.023) more at risk of being in the high BMI z-score trajectory group. Prenatal cigarette smoking was positively related to SGA at birth, but SGA was inversely related to BMI z-score at 4 years. The direct effect (0.19, 95% CI: 0.18, 0.19; P value BMI z-score among 4-year-old children was stronger and in the opposite direction of the indirect effect (-0.04, 95% CI: -0.04, -0.04; P value BMI z-score group, as well with SGA. The effects of prenatal smoking on BMI z-score at 4 years appears to act through pathways other than SGA.

    The current study examined the relationship between mathematics and attention, working memory, and visual memory in children with heavy prenatal alcohol exposure and controls. Subjects were 56 children (29 AE, 27 CON) who were administered measures of global mathematics achievement (WRAT-3 Arithmetic & WISC-III Written Arithmetic), attention, (WISC-III Digit Span forward and Spatial Span forward), working memory (WISC-III Digit Span backward and Spatial Span backward), and visual memory (CANTAB Spatial Recognition Memory and Pattern Recognition Memory). The contribution of cognitive domains to mathematics achievement was analyzed using linear regression techniques. Attention, working memory, and visual memory data were entered together on Step 1 followed by group on Step 2, and the interaction terms on Step 3. Model 1 accounted for a significant amount of variance in both mathematics achievement measures; however, model fit improved with the addition of group on Step 2. Significant predictors of mathematics achievement were Spatial Span forward and backward and Spatial Recognition Memory. These findings suggest that deficits in spatial processing may be related to math impairments seen in FASD. In addition, prenatal alcohol exposure was associated with deficits in mathematics achievement, above and beyond the contribution of general cognitive abilities.

    The present experiment assessed motor response programming and movement time in children with histories of heavy prenatal alcohol exposure (PEA). Alcohol-exposed children between the ages of 7 and 17 years were classified into two groups: Fetal Alcohol Syndrome (FAS: n=9) and children with PEA (PEA: n=19) but who did not have the defining characteristics of FAS. The FAS and PEA children were compared with non-alcohol-exposed children (NC: n=23) when completing two tasks: a simple reaction time task (RT alone condition) and a reaction plus movement task (RT+Move condition). The movement involved responding to an imperative stimulus signal and depressing three target buttons in a set sequence. Participants completed 24 trials each for the RT alone and RT+Move response conditions. Results indicated no significant differences in performance among FAS, PEA, and NC groups during the RT alone condition. However, during the RT+Move condition, the FAS group produced significantly longer and more variable RTs than the PEA and NC groups, which produced comparable RTs. The FAS group also produced significantly slower movement times when moving to all three targets, whereas movement time variability did not significantly differ as a function of group. The observed results indicate children with FAS experience deficits in response programming and movement time production. 2010 Elsevier Inc. All rights reserved.

    This manuscript provides an overview of the current scientific literature on the impact of maternal drug use, specifically opioids and cocaine, during pregnancy on the acute and long-term outcomes of infants and toddlers from birth through age 3 years. Emphasis with regard to opioids is placed on heroin and opioid substitutes used to treat opioid addiction, including methadone, which has long been regarded as the standard of care in pregnancy, and buprenorphine, which is increasingly being investigated and prescribed as an alternative to methadone. Controlled studies comparing methadone at high and low doses, as well as those comparing methadone with buprenorphine, are highlighted and the diagnosis and management of neonatal abstinence syndrome is discussed. Over the past two decades, attention of the scientific and lay communities has also been focused on the potential adverse effects of cocaine and crack cocaine, especially during the height of the cocaine epidemic in the United States. Herein, the findings are summarized from prospective studies comparing cocaine-exposed with non-cocaine-exposed infants and toddlers with respect to anthropometric growth, infant neurobehavior, visual and auditory function, and cognitive, motor, and language development. The potentially stigmatizing label of the so-called "crack baby" preceded the evidence now accumulating from well-designed prospective investigations that have revealed less severe sequelae in the majority of prenatally exposed infants than originally anticipated. In contrast to opioids, which may produce neonatal abstinence syndrome and infant neurobehavioral deficits, prenatal cocaine exposure appears to be associated with what has been described as statistically significant but subtle decrements in neurobehavioral, cognitive, and language function, especially when viewed in the context of other exposures and the caregiving environment which may mediate or moderate the effects. Whether these early findings may

    The influence of particulate air pollution on respiratory health starts in utero. Fetal lung growth and structural development occurs in stages; thus, effects on postnatal respiratory disorders may differ based on timing of exposure. We implemented an innovative method to identify sensitive windows for effects of prenatal exposure to particulate matter with a diameter less than or equal to 2.5 μm (PM2.5) on children's asthma development in an urban pregnancy cohort. Analyses included 736 full-term (≥37 wk) children. Each mother's daily PM2.5 exposure was estimated over gestation using a validated satellite-based spatiotemporal resolved model. Using distributed lag models, we examined associations between weekly averaged PM2.5 levels over pregnancy and physician-diagnosed asthma in children by age 6 years. Effect modification by sex was also examined. Most mothers were ethnic minorities (54% Hispanic, 30% black), had 12 or fewer years of education (66%), and did not smoke in pregnancy (80%). In the sample as a whole, distributed lag models adjusting for child age, sex, and maternal factors (education, race and ethnicity, smoking, stress, atopy, prepregnancy obesity) showed that increased PM2.5 exposure levels at 16-25 weeks gestation were significantly associated with early childhood asthma development. An interaction between PM2.5 and sex was significant (P = 0.01) with sex-stratified analyses showing that the association exists only for boys. Higher prenatal PM2.5 exposure at midgestation was associated with asthma development by age 6 years in boys. Methods to better characterize vulnerable windows may provide insight into underlying mechanisms.

    Maternal anxiety during pregnancy can negatively affect fetal neurodevelopment, predisposing the offspring to a higher risk of behavioral and emotional problems later in life. The current study investigates the association between maternal anxiety during pregnancy and child affective picture processing using event-related brain potentials (ERPs). Mothers reported anxiety during the second trimester using the anxiety subscale of the Symptom Checklist (SCL-90). At age 4 years, child affective picture processing (N = 86) was measured by recording ERPs during viewing of neutral, pleasant, and unpleasant pictures selected from the International Affective Pictures System. The late positive potential (LPP)-an ERP component reflecting individual differences in affective processing-was used as child outcome. The expected positive association between maternal anxiety and LPP amplitude for unpleasant pictures was not found. Nevertheless, we found a positive association between maternal anxiety during pregnancy and LPP amplitudes for neutral pictures in the middle and late time window at anterior locations (all p anxiety and gestational age at birth and after FDR correction for multiple comparisons. Our study provides neurophysiological evidence that children prenatally exposed to higher maternal anxiety devote more attentional resources to neutral pictures, but not to unpleasant pictures. Possibly, these children show enhanced vigilance for threat when viewing neutral pictures. Although useful in dangerous environments, this enhanced vigilance may predispose children prenatally exposed to higher maternal anxiety to developing behavioral and/or emotional problems later in life.

    Oxidative stress has been linked to many obesity-related conditions among children including cardiovascular disease, diabetes mellitus and hypertension. Exposure to environmental chemicals such as phthalates, ubiquitously found in humans, may also generate reactive oxygen species and subsequent oxidative stress. We examined longitudinal changes of 8-isoprostane urinary concentrations, a validated biomarker of oxidative stress, and associations with maternal prenatal urinary concentrations of phthalate metabolites for 258 children at 5, 9 and 14 years of age participating in a birth cohort residing in an agricultural area in California. Phthalates are endocrine disruptors, and in utero exposure has been also linked to altered lipid metabolism, as well as adverse birth and neurodevelopmental outcomes. We found that median creatinine-corrected 8-isoprostane concentrations remained constant across all age groups and did not differ by sex. Total cholesterol, systolic and diastolic blood pressure were positively associated with 8-isoprostane in 14-year-old children. No associations were observed between 8-isoprostane and body mass index (BMI), BMI Z-score or waist circumference at any age. Concentrations of three metabolites of high molecular weight phthalates measured at 13 weeks of gestation (monobenzyl, monocarboxyoctyl and monocarboxynonyl phthalates) were negatively associated with 8-isoprostane concentrations among 9-year olds. However, at 14 years of age, isoprostane concentrations were positively associated with two other metabolites (mono(2-ethylhexyl) and mono(2-ethyl-5-carboxypentyl) phthalates) measured in early pregnancy. Longitudinal data on 8-isoprostane in this pediatric population with a high prevalence of obesity provides new insight on certain potential cardiometabolic risks of prenatal exposure to phthalates.

    Research shows that stress in pregnancy has powerful and enduring effects on many facets of child development, including increases in behavior problems and neurodevelopmental disorders. Theory of mind is an important aspect of child development that is predictive of successful social functioning and is impaired in children with autism. A number of factors related to individual differences in theory of mind have been identified, but whether theory of mind development is shaped by prenatal events has not yet been examined. In this study we utilized a sudden onset flood that occurred in Queensland, Australia in 2011 to examine whether disaster-related prenatal maternal stress predicts child theory of mind and whether sex of the child or timing of the stressor in pregnancy moderates these effects. Higher levels of flood-related maternal subjective stress, but not objective hardship, predicted worse theory of mind at 30 months (n=130). Further, maternal cognitive appraisal of the flood moderated the effects of stress in pregnancy on girls' theory of mind performance but not boys'. These results illuminate how stress in pregnancy can shape child development and the findings are discussed in relation to biological mechanisms in pregnancy and stress theory.

    It is investigated a state of the hypophysis thyroid system at 44 pregnant women in age 19-36 years, which were irradiated by low dozes during the Chernobyl NPP accident and evacuated from the contaminated zone in first 10 days. The average doze of internal irradiation of the thyroid for pregnant women is equal 4,374 +- 1,364 mGy and for irradiated prenatally children -5,283 +- 1,454 mGy. The researches of free thyroxine, triiodothyronine and thyroxine binding globulin were done by the radiation immunological method in a venous blood serum, and a thyrotropic hormone - by a set of the 'CIS Bio International' firm. The diagnosis of the thyroid pathology was confirmed by a ultrasonic research and determination of contents of thyroid hormones. The account of the internal irradiation dozes for a thyroid was conducted by means of a use of a single exponential model of a removing of iodine 131. The fetus' thyroid irradiation doze owing to a entering of radioisotopes to the mother's body was estimated by means of the dose rate on the basis of the Johnson three component model. Direct correlation between the thyroid function at pregnant women, which were irradiation by low doses, and frequency of occurrence of an endemic goiter at the children irradiated prenatally is established. At the contents of the free thyroxine 128,9 +- 4,8 nmol/l or more, triiodothyronine 1,9 +- 0,2 nmol/l or less and increase of an activity of thyrotropic hormone from 1,3 +- 0,1 μU/ml in 12 - 27 weeks of pregnancy up to 1,9 +- 0,2 μU/ml in 38-40 weeks it is possible to predict an occurrence of the thyroid pathology at the future child. Is offered to use from the 12-weak term of pregnancy a radiation immunological method of research of thyrotropic and thyroid hormones of pregnant women, subjected to radiation effect, for preventive maintenance and revealing of early disorders of a thyroid at the children irradiated prenatally. 10 refs., 1 tab

    Prenatal alcohol exposure (PAE) can cause fetal alcohol spectrum disorders (FASD) and associated neurodevelopmental impairments. It is uncertain which types of fine motor skills are most likely to be affected after PAE or which assessment tools are most appropriate to use in FASD diagnostic assessments. This systematic review examined which types of fine motor skills are impaired in children with PAE or FASD; which fine motor assessments are appropriate for FASD diagnosis; and whether fine motor impairments are evident at both "low" and "high" PAE levels. A systematic review of relevant databases was undertaken using key terms. Relevant studies were extracted using a standardized form, and methodological quality was rated using a critical appraisal tool. Twenty-four studies met inclusion criteria. Complex fine motor skills, such as visual-motor integration, were more frequently impaired than basic fine motor skills, such as grip strength. Assessment tools that specifically assessed fine motor skills more consistently identified impairments than those which assessed fine motor skills as part of a generalized neurodevelopmental assessment. Fine motor impairments were associated with "moderate" to "high" PAE levels. Few studies reported fine motor skills of children with "low" PAE levels, so the effect of lower PAE levels on fine motor skills remains uncertain. Comprehensive assessment of a range of fine motor skills in children with PAE is important to ensure an accurate FASD diagnosis and develop appropriate therapeutic interventions for children with PAE-related fine motor impairments.

    We studied the growth and development of children prenatally exposed to telbivudine used to treat chronic hepatitis B virus (HBV) infection in their mothers. Maternal abnormalities during pregnancy and delivery and infant congenital anomalies, physical development status, developmental quotient (DQ), HBV vertical transmission status, and HBV vaccination outcomes of 54 infants were evaluated (2010-2013). No fetal abnormalities were observed during pregnancy or delivery. Postpartum, three infants (5.56%) had abnormalities: ankyloglossia, cutaneous hemangioma, and vaginal canal leak. Height and weight were within the normal range at birth and at 6 weeks, but were higher than the reference at 12 months (pchildren (68.52%), abnormal or suspicious for a developmental delay (15.19%, 41/270) in 17 children (31.48%), and indicated a developmental delay (4.07%, 11/270) in seven children (12.96%). There were no significant differences in developmental delay between children prenatally exposed to telbivudine and controls (p>0.05). HBV vertical transmission was successfully blocked in all infants. The effective HBV vaccination rate was 98.15% (53/54). The growth and development of children prenatally exposed to telbivudine was normal, indicating that telbivudine treatment during pregnancy is safe and effective. Copyright © 2015.

    Full Text Available This paper presents a new initiative in the South-Eastern Health Region of Norway to establish a regional resource center focusing on services for children and adolescents aged 2–18 years with prenatal exposure to alcohol or other drugs. In Norway, the prevalence of fetal alcohol spectrum (FAS is not known but has been estimated to be between 1 and 2 children per 1000 births, while the prevalence of prenatal exposure to illicit drugs is unknown. The resource center is the first of its kind in Scandinavia and will have three main objectives: (1 provide hospital staff, community health and child welfare personnel, and special educators with information, educational courses, and seminars focused on the identification, diagnosis, and treatment of children with a history of prenatal alcohol/drug exposure; (2 provide specialized health services, such as diagnostic services and intervention planning, for children referred from hospitals in the South-Eastern Health Region of Norway; and (3 initiate multicenter studies focusing on the diagnostic process and evaluation of interventions.

    We examined the association between telomere length and prenatal tobacco exposure (PTE) in 104 children aged 4 to 14 years. Salivary telomere length (STL) was determined from salivary DNA using quantitative polymerase chain reaction. Of the children, 18% had maternal reported PTE. Mean STL was significantly lower among children with PTE (6.4 vs 7.5, P < .05). Findings extend the literature demonstrating the negative long-term effects of PTE to include a cellular marker of aging linked to multiple negative health outcomes. PMID:23927510

    Response inhibition is a distinct aspect of executive function that is frequently impaired in children with fetal alcohol spectrum disorders (FASD). We used a Go/NoGo (GNG) task in a functional MRI protocol to investigate differential activation of brain regions in the response inhibition network in children diagnosed with full or partial fetal alcohol syndrome (FAS/PFAS), compared with healthy controls. A rapid, event-related task with 120 Go and 60 NoGo trials was used to study children aged 8 to 12 years-8 with FAS/PFAS, 17 controls. Letters were projected sequentially, with Go and NoGo trials randomly interspersed across the task. BOLD signal in the whole brain was contrasted for the correct NoGo minus correct Go trials between the FAS/PFAS and control groups. Compared to the FAS/PFAS group, controls showed greater activation of the inferior frontal and anterior cingulate network linked to response inhibition in typically developing children. By contrast, the FAS/PFAS group showed greater BOLD response in dorsolateral prefrontal cortex and other middle prefrontal regions, suggesting compensation for inefficient function of pathways that normally mediate inhibitory processing. All group differences were significant after control for potential confounding variables. None of the effects of prenatal alcohol exposure on activation of the regions associated with response inhibition were attributable to the effects of this exposure on IQ. This is the first FASD GNG study in which all participants in the exposed group met criteria for a diagnosis of full FAS or PFAS. Although FASD is frequently comorbid with attention deficit hyperactivity disorder, the pattern of brain activation seen in these disorders differs, suggesting that different neural pathways mediate response inhibition in FASD and that different interventions for FASD are, therefore, warranted.

    Limited human data are available to assess the association between prenatal mercury vapor (Hg⁰)) exposure from maternal dental amalgam restorations and neurodevelopment of children. We evaluated the association between maternal dental amalgam status during gestation and children's neurodevelopmental outcomes at 5 years in the Seychelles Child Development Nutrition Study (SCDNS). Maternal amalgam status was determined prospectively in a longitudinal cohort study examining the associations of prenatal exposure to nutrients and methylmercury (MeHg) with neurodevelopment. A total of 236 mother-child pairs initially enrolled in the SCDNS in 2001 were eligible to participate. Maternal amalgam status was measured as number of amalgam surfaces (the primary metric) and number of occlusal points. The neurodevelopmental assessment battery was comprised of age-appropriate tests of cognitive, language, and perceptual functions, and scholastic achievement. Linear regression analysis controlled for MeHg exposure, maternal fatty acid status, and other covariates relevant to child development. Maternal amalgam status evaluation yielded an average of 7.0 surfaces (range 0-28) and 11.0 occlusal points (range 0-40) during pregnancy. Neither the number of maternal amalgam surfaces nor occlusal points were associated with any outcome. Our findings do not provide evidence to support a relationship between prenatal exposure to Hg⁰ from maternal dental amalgam and neurodevelopmental outcomes in children at 5 years of age. © 2013.

    To assess the relative influence of size at birth, infant growth, and late postnatal growth on intellectual functioning at 9 years of age. A follow-up, cross-sectional study. Three districts in Khon Kaen province, northeast Thailand. A total of 560 children, or 92% of former participants of a trial of iron and/or zinc supplementation during infancy. Prenatal (size at birth), early infancy (birth to 4 months), late infancy (4 months to 1 year), and late postnatal (1 to 9 years) growth. Multiple-stage least squares analyses were used to generate uncorrelated residuals of postnatal growth. Intellectual functioning was measured at 9 years using the Wechsler Intelligence Scale for Children and the Raven's Colored Progressive Matrices (Pearson). Analyses included adjustment for maternal, household, and school characteristics. Significant relationships were found between growth and IQ (Wechsler Intelligence Scale for children, third edition, Thai version), but only up to 1 year of age; overall, growth was not related to the Raven's Colored Progressive Matrices. The strongest and most consistent relationships were with length (birth, early infancy, and late infancy); for weight, only early infancy gain was consistently related to IQ. Head circumference at birth was not collected routinely; head circumference at 4 months (but not head circumference growth thereafter) was related to IQ. Late postnatal growth was not associated with any outcome. Physical growth in early infancy (and, to a lesser extent, physical growth in late infancy and at birth) is associated with IQ at 9 years of age. Early infancy may be a critical window for human development.

    Prenatal depressive symptoms have been associated with multiple adverse outcomes. Previously, we demonstrated that prenatal depressive symptoms were associated with impaired growth of the fetus and increased behavioral problems in children aged between 1.5 and 6 years. In this prospective study, we aimed to assess whether prenatal maternal depressive symptoms at 3 years have long-term consequences on brain development in a cohort of children aged 6-10 years. As a contrast, the association of paternal depressive symptoms during pregnancy and brain morphology was assessed to serve as a marker of background confounding due to shared genetic and environmental family factors. We assessed parental depressive symptoms during pregnancy with the Brief Symptom Inventory. At approximately 8 years of age, we collected structural neuroimaging data, using cortical thickness, surface area, and gyrification as outcomes (n = 654). We found that exposure to prenatal maternal depressive symptoms during pregnancy was associated with a thinner superior frontal cortex in the left hemisphere. Additionally, prenatal maternal depressive symptoms were related to larger caudal middle frontal area in the left hemisphere. Maternal depressive symptoms at 3 years were not associated with cortical thickness, surface area, or gyrification in the left and right hemispheres. No effects of paternal depressive symptoms on brain morphology were observed. Prenatal maternal depressive symptoms were associated with differences in brain morphology in children. It is important to prevent, identify, and treat depressive symptoms during pregnancy as it may have long-term consequences on child brain development. © 2016 Wiley Periodicals, Inc.

    Full Text Available Background: While current research suggests that genetic factors confer the greatest risk for the development of tic disorders, studies of environmental factors are relatively few, with a lack of consistent risk factors across studies. Our aim is to analyze the association of tic disorders with exposure to prenatal and perinatal morbidity. Methods: This was a nested case–control study design. Cases and controls were selected and identified from a mainstream, school-based sample. The diagnosis of tic disorders was assigned by a movement disorder neurologist using ‘Diagnostic and statistical manual of mental disorders, 4th edition, text revision’ criteria, and neuropsychiatric comorbidities were screened using the Spanish computerized version of the Diagnostic Interview Schedule for Children Predictive Scale. Information regarding the exposure to pre-perinatal risk factors was collected by a retrospective review of the birth certificates. Logistic regression analyses were then performed to test the association of tic disorders with pre-perinatal risk factors.Results: Out of 407 participants, complete pre-perinatal data were available in 153 children (64 with tics and 89 without tics;. After adjusting for family history of tics, neonatal respiratory distress syndrome, body mass index, prenatal infection, and coexisting comorbid neuropsychiatric disturbances, tic disorders were associated with prenatal exposure to tobacco (odds ratio [OR] = 3.07, 95% confidence interval [CI] 1.24–7.60, p = 0.007, and cesarean section (OR = 5.78, 95% CI 1.60–20.91, p = 0.01.Discussion: This nested case–control study of children with tic disorders demonstrates higher adjusted odds for tics in children with exposure to cesarean delivery and maternal smoking. Longitudinal, population-based samples are required to confirm these results.

    Some evidence suggests that fluoride may be neurotoxic to children. Few of the epidemiologic studies have been longitudinal, had individual measures of fluoride exposure, addressed the impact of prenatal exposures or involved more than 100 participants. Our aim was to estimate the association of prenatal exposure to fluoride with offspring neurocognitive development. We studied participants from the Early Life Exposures in Mexico to Environmental Toxicants (ELEMENT) project. An ion-selective electrode technique was used to measure fluoride in archived urine samples taken from mothers during pregnancy and from their children when 6-12 y old, adjusted for urinary creatinine and specific gravity, respectively. Child intelligence was measured by the General Cognitive Index (GCI) of the McCarthy Scales of Children's Abilities at age 4 and full scale intelligence quotient (IQ) from the Wechsler Abbreviated Scale of Intelligence (WASI) at age 6-12. We had complete data on 299 mother-child pairs, of whom 287 and 211 had data for the GCI and IQ analyses, respectively. Mean (SD) values for urinary fluoride in all of the mothers (n=299) and children with available urine samples (n=211) were 0.90 (0.35) mg/L and 0.82 (0.38) mg/L, respectively. In multivariate models we found that an increase in maternal urine fluoride of 0.5mg/L (approximately the IQR) predicted 3.15 (95% CI: -5.42, -0.87) and 2.50 (95% CI -4.12, -0.59) lower offspring GCI and IQ scores, respectively. In this study, higher prenatal fluoride exposure, in the general range of exposures reported for other general population samples of pregnant women and nonpregnant adults, was associated with lower scores on tests of cognitive function in the offspring at age 4 and 6-12 y. https://doi.org/10.1289/EHP655.

    To study the genetic effects in children exposed to radiation in utero as a result of the Chornobyl nuclear power plant accident accounting the total radiation doses and equivalent radiation doses to the red bone marrow. Incidence of minor developmental anomalies was studied in children exposed to radiation in utero (study group) and in the control group (1144 subjects surveyed in total). Cytogenetic tests using the method of differential G-banding of chromosomes were conducted in 60 children of both study and control groups (10-12-year-olds) and repeatedly in 39 adolescents (15-17-year-olds). A direct correlation was found between the number of minor developmental anomalies and fetal dose of radiation, and a reverse one with fetal gestational age at the time of radiation exposure. Incidence of chromosomal damage in somatic cells of 10-12-year-old children exposed prenatally was associated with radiation dose to the red bone marrow. The repeated testing has revealed that an increased level of chromosomal aberrations was preserved in a third of adolescents. The persons exposed to ionizing radiation at prenatal period should be attributed to the group of carcinogenic risk due to persisting increased levels of chromosome damage. This article is a part of a Special Issue entitled "The Chornobyl Nuclear Accident: Thirty Years After".

    Some experimental and human data suggest that exposure to polychlorinated biphenyls (PCBs) may induce ototoxicity, though results of previous epidemiologic studies are mixed and generally focus on either prenatal or postnatal PCB concentrations exclusively. Our aim was to evaluate the association between pre- and postnatal PCB concentrations in relation to cochlear status, assessed by distortion product otoacoustic emissions (DPOAEs), and to further clarify the critical periods in development where cochlear status may be most susceptible to PCBs. A total of 351 children from a birth cohort in eastern Slovakia underwent otoacoustic testing at 45 months of age. Maternal pregnancy, cord, and child 6-, 16-, and 45-month blood samples were collected and analyzed for PCB concentrations. At 45 months of age, DPOAEs were assessed at 11 frequencies in both ears. Multivariate, generalized linear models were used to estimate the associations between PCB concentrations at different ages and DPOAEs, adjusting for potential confounders. Maternal and cord PCB-153 concentrations were not associated with DPOAEs at 45 months. Higher postnatal PCB concentrations at 6-, 16-, and 45-months of age were associated with lower (poorer) DPOAE amplitudes. When all postnatal PCB exposures were considered as an area-under-the-curve metric, an increase in PCB-153 concentration from the 25th to the 75th percentile was associated with a 1.6-dB SPL (sound pressure level) decrease in DPOAE amplitude (95% CI: -2.6, -0.5; p = 0.003). In this study, postnatal rather than maternal or cord PCB concentrations were associated with poorer performance on otoacoustic tests at age 45 months.

    The aim of this study was to evaluate the effect of prenatal and postnatal malnutrition on the intellectual functioning of early school-aged children. We followed the offspring of women who had participated in a trial of prenatal supplementation with different combinations of micronutrients and who remained resident in the study field. We measured their intellectual functioning using the Wechsler intelligence scale for children (WISC-IV). Height-for-age, weight-for-age, and body mass index (BMI)-for-age were used as anthropometric nutritional status indices. Four of the 5 composite scores derived from the WISC-IV, except for working memory index (WMI), were significantly lower in low birth weight children after adjusting for confounds. All 5 composite scores, including full-scale intelligence quotient (FSIQ), verbal comprehension index (VCI), WMI, perceptual reasoning index (PRI), and processing speed index (PSI) were significant lower in stunted and underweight children. The differences in the means of WISC-IV test scores were greatest between stunted and nonstunted children. The means for FSIQ, VCI, WMI, PRI, and PSI were as follows: 5.88 (95% confidence interval [CI]: 2.84-8.92), 5.08 (95% CI: 1.12-8.41), 4.71 (95% CI: 1.78-7.66), 6.13 (95% CI: 2.83-9.44), and 5.81 (95% CI: 2.61-9.00). These means were lower in stunted children after adjusting for confounds. Our results suggest the important influences of low birth weight and postnatal malnutrition (stunting, low body weight) on intellectual functioning in early school-aged children.

    Full Text Available Abstract Background Endocrine disrupting chemicals have been hypothesized to play a role in the obesity epidemic. Long-term effects of prenatal exposure to non-persistent pesticides on body composition have so far not been investigated. The purpose of this study was to assess possible effects of prenatal exposure to currently used pesticides on children's growth, endocrine and reproductive function. Methods In a prospective study of 247 children born by women working in greenhouses in early pregnancy, 168 were categorized as prenatally exposed to pesticides. At three months (n = 203 and at 6 to11 years of age (n = 177 the children underwent a clinical examination and blood sampling for analysis of IGF-I, IGFBP3 and thyroid hormones. Body fat percentage at age 6 to11 years was calculated from skin fold measurements. Pesticide related associations were tested by linear multiple regression analysis, adjusting for relevant confounders. Results Compared to unexposed children birth weight and weight for gestational age were lower in the highly exposed children: -173 g (-322; -23, -4.8% (-9.0; -0.7 and medium exposed children: -139 g (-272; -6, -3.6% (-7.2; -0.0. Exposed (medium and highly together children had significantly larger increase in BMI Z-score (0.55 SD (95% CI: 0.1; 1.0 from birth to school age and highly exposed children had 15.8% (0.2; 34.6 larger skin folds and higher body fat percentage compared to unexposed. If prenatally exposed to both pesticides and maternal smoking (any amount, the sum of four skin folds was 46.9% (95% CI: 8.1; 99.5 and body fat percentage 29.1% (95% CI: 3.0; 61.4 higher.

    Evolving animal studies and limited epidemiological data show that prenatal air pollution exposure is associated with childhood obesity. Timing of exposure and child sex may play an important role in these associations. We applied an innovative method to examine sex-specific sensitive prenatal windows of exposure to PM 2.5 on anthropometric measures in preschool-aged children. Analyses included 239 children born ≥ 37 weeks gestation in an ethnically-mixed lower-income urban birth cohort. Prenatal daily PM 2.5 exposure was estimated using a validated satellite-based spatio-temporal model. Body mass index z-score (BMI-z), fat mass, % body fat, subscapular and triceps skinfold thickness, waist and hip circumferences and waist-to-hip ratio (WHR) were assessed at age 4.0 ± 0.7 years. Using Bayesian distributed lag interaction models (BDLIMs), we examined sex differences in sensitive windows of weekly averaged PM 2.5 levels on these measures, adjusting for child age, maternal age, education, race/ethnicity, and pre-pregnancy BMI. Mothers were primarily Hispanic (55%) or Black (26%), had ≤ 12 years of education (66%) and never smoked (80%). Increased PM 2.5 exposure 8-17 and 15-22 weeks gestation was significantly associated with increased BMI z-scores and fat mass in boys, but not in girls. Higher PM 2.5 exposure 10-29 weeks gestation was significantly associated with increased WHR in girls, but not in boys. Prenatal PM 2.5 was not significantly associated with other measures of body composition. Estimated cumulative effects across pregnancy, accounting for sensitive windows and within-window effects, were 0.21 (95%CI = 0.01-0.37) for BMI-z and 0.36 (95%CI = 0.12-0.68) for fat mass (kg) in boys, and 0.02 (95%CI = 0.01-0.03) for WHR in girls, all per µg/m 3 increase in PM 2.5 . Increased prenatal PM 2.5 exposure was more strongly associated with indices of increased whole body size in boys and with an indicator of body shape in girls. Methods to better characterize

    Prenatal polycyclic aromatic hydrocarbon (PAH) exposure has been shown to increase DNA adduct levels and to affect neurodevelopment. Micronutrients may modify the adverse effect of PAH on neurodevelopment. Thus, we examined if micronutrient concentrations modified the association between PAH exposure and neurodevelopmental outcomes. 151 children from a birth cohort who had micronutrient concentrations measured in cord blood and completed the Child Behavioral Checklist (CBCL), between the ages of 6 and 9 years, were evaluated. Prenatal airborne PAH exposure was measured by personal air monitoring. The betas and 95% CI for the associations of antioxidant concentrations and PAH exposure with each of the outcomes of CBCL raw score and dichotomized standardized T-score (based on clinical cutpoints) were estimated, respectively, by multivariable poisson and logistic models. Children below the median for alpha-tocopherol and gamma-tocopherol concentrations, compared to those above, were more likely to have thought problems, aggressive behavior and externalizing problems (pPAH in relation to CBCL symptoms (e.g., internalizing and externalizing problems, pPAH exposure. Future research to confirm these findings are warranted given the importance of identifying modifiable factors for reducing harmful PAH effects. Copyright © 2015 Elsevier Inc. All rights reserved.

    Children with fetal alcohol spectrum disorder (FASD) or prenatal alcohol exposure (PAE) frequently exhibit impairment on tasks measuring inhibition. The objective of this study was to determine if a performance-based relationship exists between psychometric tests and eye movement tasks in children with FASD. Participants for this dataset were aged 5-17 years and included those diagnosed with an FASD (n=72), those with PAE but no clinical FASD diagnosis (n=21), and typically developing controls (n=139). Participants completed a neurobehavioral test battery, which included the NEPSY-II subtests of auditory attention, response set, and inhibition. Each participant completed a series of saccadic eye movement tasks, which included the antisaccade and memory-guided tasks. Both the FASD and the PAE groups performed worse than controls on the subtest measures of attention and inhibition. Compared with controls, the FASD group made more errors on the antisaccade and memory-guided tasks. Among the combined FASD/PAE group, inhibition and switching errors were negatively correlated with direction errors on the antisaccade task but not on the memory-guided task. There were no significant correlations in the control group. These data suggests that response inhibition deficits in children with FASD/PAE are associated with difficulty controlling saccadic eye movements which may point to overlapping brain regions damaged by prenatal alcohol exposure. The results of this study demonstrate that eye movement control tasks directly relate to outcome measures obtained with psychometric tests that are used during FASD diagnosis, and may therefore help with early identification of children who would benefit from a multidisciplinary diagnostic assessment.

    We sought to determine whether prenatal co-exposure to As, Cd, Hg, Mn, and Pb was associated with impaired neurodevelopment in preschool children from the Spanish Environment and Childhood (INMA) Project, using the placenta as exposure matrix. We measured metal levels in placenta tissue samples randomly selected from five of the seven population-based birth cohorts participating in the INMA Project, collected between 2000 and 2008. Neuropsychological assessment of cognitive and motor function was carried through the use of the McCarthy Scales of Children's Abilities (MSCA) at the age of 4-5years. Data on placental metal levels, MSCA scores, and relevant covariates was available for 302 children. Mn was detected in all placental samples, Cd in nearly all placentas (99%) and As, Hg, and Pb in 22%, 58%, and 17% of the placentas, respectively. After adjusting for potential confounders, detectable As levels were associated with decrements in global and verbal executive functions and quantitative abilities; detectable Hg was associated with lower scores on the verbal function of posterior cortex in a dose-response manner, and non-linearly related to poorer motor function and gross motor skills; and Mn levels were associated with decrement in perceptual-performance skills in a dose-response manner but with better memory span and quantitative skills. A synergistic interactive effect was found between As and Pb with respect to the general cognitive score, whereas an antagonistic interaction was found between Mn and Hg. Prenatal exposure to As and Hg may be a risk factor for cognitive and motor impairment in children, while the effects of Cd and Mn on neurodevelopment are less clear. Future studies should examine combined and interactive effects of exposure to multiple metals during vulnerable periods of brain development prospectively. Copyright © 2017 Elsevier B.V.

  11. Benefits of reducing prenatal exposure to coal-burning pollutants to children's neurodevelopment in China

    Coal burning provides 70% of the energy for China's industry and power, but releases large quantities of polycyclic aromatic hydrocarbons (PAHs) and other pollutants. PAHs are reproductive and developmental toxicants, mutagens, and carcinogens. We evaluated the benefit to neurobehavioral development from the closure of a coal-fired power plant that was the major local source of ambient PAHs. The research was conducted in Tongliang, Chongqing, China, where a coal-fired power plant operated seasonally before it was shut down in May 2004. Two identical prospective cohort studies enrolled nonsmoking women and their newborns in 2002 (before shutdown) and 2005 (after shutdown). Prenatal PAH exposure was measured by PAH-DNA adducts (benzo(a)pyrene-DNA) in umbilical cord blood. Child development was assessed by the Gesell Developmental Schedules at 2 years of age. Prenatal exposure to other neurotoxicants and potential confounders (including lead, mercury, and environmental tobacco smoke) was measured. We compared the cohorts regarding the association between PAH-DNA adduct levels and neurodevelopmental outcomes. Significant associations previously seen in 2002 between elevated adducts and decreased motor area developmental quotient (DQ) (p = 0.043) and average DQ (p = 0.047) were not observed in the 2005 cohort (p = 0.546 and p = 0.146). However, the direction of the relationship did not change. The findings indicate that neurobehavioral development in Tongliang children benefitedby elimination of PAH exposure from the coal-burning plant, consistent with the significant reduction in PAH-DNA adducts in cord blood of children in the 2005 cohort. The results have implications for children's environmental health in China and elsewhere.

    An increasing consumption of opioids in the general population has been reported in several countries also among pregnant women. Limited information is available regarding the effect of prenatal exposure to analgesic opioids on long-term neurocognitive function in children. The primary aim of the study was to determine the association between prenatal exposure to analgesic opioids and language competence and communication skills at 3 years of age. The Norwegian Mother and Child Cohort Study (MoBa) prospectively included pregnant women during the period from 1999 to 2008. Participants reported medication use at pregnancy weeks 17-18 and 30, and 6 months after birth. Children's language competence and communication skills were reported by mothers on validated scales. A total of 45 211 women with 51 679 singleton pregnancies were included. The use of analgesic opioids was reported in 892 pregnancies (1.7%). In adjusted analyses, no association between opioid use and reduced language competence or communication skills was found, OR = 1.04 (95%CI: 0.89-1.22) and OR = 1.10 (95%CI: 0.95-1.27), respectively. Both pain and use of paracetamol were associated with a small reduction in communication skills. No such association was found for language competence. The use of analgesic opioids in pregnant women does not seem to affect language development or communication skills in children at 3 years of age. Copyright © 2017 John Wiley & Sons, Ltd.

    BACKGROUND: Previous studies have evaluated the effect of medical diagnostic radiation on brain tumors. Recent cohort studies have reported an increased risk associated with exposure to head CT scans. METHODS: Information regarding medical conditions, including prenatal and postnatal exposure...... to medical diagnostic radiation, was obtained from CEFALO, a multicenter case-control study performed in Denmark, Norway, Sweden, and Switzerland through face-to-face interview. Eligible cases of childhood and adolescent brain tumors (CABT) were ages 7 to 19 years, diagnosed between January 1, 2004...... and August 31, 2008, and living in the participating countries (n = 352). The cases were matched by age, sex, and region to 646 population-based controls. RESULTS: Prenatal exposure to medical diagnostic radiation and postnatal exposure to X-rays were not associated with CABTs. A higher risk estimate...

    To examine whether cumulative family discrimination and acculturation stress (prenatally to 24 months postpartum) among Mexican-origin adolescent mothers and their mother-figures predicted children's socio-emotional functioning and academic achievement at 5 years of age, and the role of maternal depressive symptoms and mother-child interactions in the association. Mexican-origin families (N = 204) with an adolescent mother, a child, and a mother-figure participated in a 6-wave longitudinal study (2007-2013). Families were recruited and interviewed during the adolescent mother's pregnancy; adolescent mothers, mother-figures, and children were then assessed annually for the next 5 years using a combination of interview-based survey and observational methods. Maternal reports of children's socio-emotional behaviors (measured using the Child Behavior Checklist) and children's academic achievement (assessed with the Woodcock Johnson III Tests of Achievement/Bateria III Woodcock-Muñoz) were used. Structural equation modeling revealed that greater cumulative family discrimination and acculturation stress from pregnancy to 24 months postpartum predicted higher adolescent mothers' depressive symptoms, greater mother-child intrusive interactions, and less mother sensitivity at 36 months postpartum. Maternal depressive symptoms were positively related to children's CBCL symptoms at 60 months postpartum. Greater cumulative discrimination and acculturation stressors directly predicted children's lower Woodcock Johnson/Bateria test scores after accounting for socio-economic status. Mexican-origin adolescent mothers' and mother figures' cumulative discrimination and acculturation stress from pregnancy through children's second birthday predicted children's socio-emotional and academic achievement at age 5. Overall, the findings underscore the cumulative impact of these stressors on well-being in a population with substantial public health significance.

    The ice storm in the winter of 1998 left three million people in Quebec without power for as long as 40 days. This study recruited 224 women who were pregnant during the storm or who became pregnant within 3 months after the storm. The study examined the effects of prenatal maternal stress (PNMS) in an effort to fill gaps in literature regarding prenatal stress and increased risks and to assist in the development of preventive interventions for pregnant women who have experienced stress or trauma. Natural disaster studies provide good opportunities to study the effects of PNMS, as effects are random across large numbers of women and can be assessed independently of the pregnant women's own personality traits. The study examined whether there was an effect of the timing and severity of the ice storm on perinatal outcomes and later health; intellectual and linguistic functioning at two and a half and five years of age; behavioural and attention problems at four and five and a half years of age and physical features. The study concluded that pregnant women are a risk group and need proper interventions as children experienced delays or deficiencies in several key developmental areas. tabs., figs.

    BackgroundPrenatal maternal obesity has been associated with an increased risk of neurocognitive problems in childhood, but there are fewer studies on executive functioning.MethodsTests and questionnaires to assess neurodevelopment, executive functioning, and the ability to delay gratification were conducted in 113 children (mean (SD)=4.24 (0.63) years of age) born to mothers with very severe obesity (SO, body mass index (BMI)⩾40 kg/m 2 , n=51) or to lean mothers (BMI⩽25 kg/m 2 , n=62).ResultsPrenatal maternal SO predicted poorer neurodevelopment (unstandardized regression coefficient (B)=-0.42, 95% confidence interval (CI) (-0.82; -0.02)), worse problem-solving (odd ratio (OR)=0.60, 95% CI (1.13; 0.07)), and fine motor skills (OR=4.91, 95% CI (1.27; 19.04)), poorer executive functioning in areas of attention, inhibitory control, and working memory (standardized B=3.75, 95% CI (1.01; 13.93)) but not in self-gratification delay. The effects were independent of maternal concurrent psychological well-being and child's BMI, but not independent of maternal education.ConclusionFuture studies should investigate whether perinatal management of maternal obesity could prevent adverse outcomes in child neurodevelopment.

    Background: Some evidence suggests that fluoride may be neurotoxic to children. Few of the epidemiologic studies have been longitudinal, had individual measures of fluoride exposure, addressed the impact of prenatal exposures or involved more than 100 participants. Objective: Our aim was to estimate the association of prenatal exposure to fluoride with offspring neurocognitive development. Methods: We studied participants from the Early Life Exposures in Mexico to Environmental Toxicants (ELEMENT) project. An ion-selective electrode technique was used to measure fluoride in archived urine samples taken from mothers during pregnancy and from their children when 6–12 y old, adjusted for urinary creatinine and specific gravity, respectively. Child intelligence was measured by the General Cognitive Index (GCI) of the McCarthy Scales of Children’s Abilities at age 4 and full scale intelligence quotient (IQ) from the Wechsler Abbreviated Scale of Intelligence (WASI) at age 6–12. Results: We had complete data on 299 mother–child pairs, of whom 287 and 211 had data for the GCI and IQ analyses, respectively. Mean (SD) values for urinary fluoride in all of the mothers (n=299) and children with available urine samples (n=211) were 0.90 (0.35) mg/L and 0.82 (0.38) mg/L, respectively. In multivariate models we found that an increase in maternal urine fluoride of 0.5mg/L (approximately the IQR) predicted 3.15 (95% CI: −5.42, −0.87) and 2.50 (95% CI −4.12, −0.59) lower offspring GCI and IQ scores, respectively. Conclusions: In this study, higher prenatal fluoride exposure, in the general range of exposures reported for other general population samples of pregnant women and nonpregnant adults, was associated with lower scores on tests of cognitive function in the offspring at age 4 and 6–12 y. https://doi.org/10.1289/EHP655 PMID:28937959

  18. Does prenatal care increase access to child immunization? Gender bias among children in India.

    Prenatal care appears to serve as a trigger in increasing the chances for access to subsequent health care services. Although several previous studies have investigated this connection, none have focused specifically on how parents' behavior differs before and after learning the gender of their babies. Investigating parents' behavioral changes after the child's birth provides a quasi-natural experiment with which to test the gender discrimination hypothesis. This issue was examined here, using a rich family health survey data set from India. We find evidence for the triggering effect of prenatal care on immunization only among rural boys, but we find no compelling evidence for this effect among other sub-samples. This finding suggests two things, which are not mutually exclusive. One is that the information spillover from prenatal care has a much larger impact in rural areas, where alternative sources of information are scarce, compared with urban areas. The other is that the sex of a child is a critical factor in producing different levels of health care behavior in rural areas, where sons are favored and more valued than in urban areas.

    2017-01-01

    Background: Perfluoroalkyl substances (PFAS) may affect body mass index (BMI) and other components of cardiometabolic (CM) risk during childhood, but evidence is scarce and inconsistent. Objectives: We estimated associations between prenatal PFAS exposures and outcomes relevant to cardiometabolic risk, including a composite CM-risk score. Methods: We measured perfluorohexanesulfonic acid (PFHxS), perfluorooctanesulfonic acid (PFOS), perfluorooctanoic acid (PFOA), and perfluorononanoic acid (PFNA) in maternal plasma (first trimester). We assessed weight gain from birth until 6 mo. At 4 and 7 y, we calculated the age- and sex-specific z-scores for BMI, waist circumference (WC), and blood pressure (BP) (n≈1,000). At age 4, we calculated the age-, sex-, and region-specific z-scores for cholesterol, triglycerides (TGs), high-density (HDL-C), and low-density lipoprotein cholesterol (LDL-C) (n=627). At age 4, we calculated a CM-risk score (n=386) as the sum of the individual age-, sex-, and region-specific z-scores for WC, BP, HDL-C, and TGs. We used the average between the negative of HDL-C z-score and TGs z-score to give similar weight to lipids and the other components in the score. A higher score indicates a higher cardiometabolic risk at age 4. Results: PFOS and PFOA were the most abundant PFAS (geometric mean: 5.80 and 2.32 ng/mL, respectively). In general, prenatal PFAS concentrations were not associated with individual outcomes or the combined CM-risk score. Exceptions were positive associations between prenatal PFHxS and TGs z-score [for a doubling of exposure, β=0.11; 95% confidence interval (CI): 0.01, 0.21], and between PFNA and the CM-risk score (β=0.60; 95% CI: 0.04, 1.16). There was not clear or consistent evidence of modification by sex. Conclusions: We observed little or no evidence of associations between low prenatal PFAS exposures and outcomes related to cardiometabolic risk in a cohort of Spanish children followed from birth until 7 y. https

    Full Text Available Objectives: To assess the attitudes of pregnant women and mothers of children with orofacial clefts toward prenatal diagnosis of clefts and elective termination of pregnancy, and to investigate their opinion about who makes reproductive decisions in the family. Design: Two hundred subjects were included in the study prospectively regarding hypothetical prenatal ultrasound diagnosis of clefts. Setting: The study was done in a private tertiary care institution and a teaching hospital. Subjects/Participants: One hundred pregnant women consulting the Obstetrics department and 100 mothers of children with orofacial clefts in the Cleft and Craniofacial Unit were selected. Materials and Methods: Group I subjects were interviewed using a questionnaire and were shown preoperative and postoperative pictures of children treated for cleft lip and palate. Group II subjects were interviewed using a questionnaire. Results: Only 3% of Group I subjects and 2% of Group II opined that they would choose the elective termination of pregnancy if the fetus was diagnosed with a cleft on an ultrasound scan. In Group II, 70% subjects wished to have known about pregnancy affected with cleft prenatally and 96% said they would definitely avail ultrasound scans to determine pregnancy affected by clefts in future. Conclusions: Majority of the respondents from both the groups chose to continue with the pregnancy affected with a cleft when questioned regarding hypothetical prenatal ultrasound diagnosis of the cleft.

    The main purpose of the present study was to test the hypothesis that the depressed lung growth attributable to prenatal exposure to polycyclic aromatic hydrocarbons (PAH) may be modified by the intake of antihistamine medications. Individual prenatal PAH exposure was assessed by personal air monitoring in 176 children who were followed over nine years, in the course of which outdoor residential air monitoring, allergic skin tests for indoor allergens, lung function tests (FVC, FEV(1), FEV(05), and FEF(25-75)) were performed. The analysis with the General Estimated Equation (GEE) showed no association between prenatal PAH exposure and lung function in the group of children who were reported to be antihistamine users. However, in the group of antihistamine non-users all lung function tests except for FEF(25-75) were significantly and inversely associated with prenatal airborne PAH exposure. The results of the study suggest that the intake of antihistamine medications in early childhood may inhibit the negative effect of fetal PAH exposure on lung growth and provides additional indirect evidence for the hypothesis that lung alterations in young children resulting from PAH exposure may be caused by the allergic inflammation within lung. © 2014 Wiley Periodicals, Inc.

    It has been suggested that prenatal maternal stress may increase the risk of childhood externalizing disorders, yet no large cohort study has investigated this association across a large range of acute stressors. Our objective was to estimate the association between prenatal stressful events and risk of offspring conduct disorder and hyperactivity. We used data from 10,184 mother-offspring pairs from the United Kingdom-based Avon Longitudinal Study of Parents and Children. Mothers self-reported 42 prenatal stressful life events at 18 weeks' gestation. Symptoms of conduct disorder and hyperactivity in their offspring were measured at 6, 9, 11, 13, and 16 years of age using the Strengths and Difficulties Questionnaire. The primary outcome was membership in high-symptom trajectories of 1) conduct disorder and 2) hyperactivity throughout childhood, identified using latent class growth modeling. Multinomial logistic regression models estimated the association between prenatal stress and both conduct disorder and hyperactivity, after adjusting for sex, parental education, low birth weight, preterm birth, parental social class, maternal smoking and drinking, maternal mental health, offspring stressful life events, and offspring depressive and anxious symptoms. Those exposed to the highest quartile of prenatal stress were more likely to belong to the high symptom trajectory for hyperactivity (B = 0.46, p < .05) and conduct disorder (B = 0.88, p < .01), respectively. Prenatal stress further demonstrated a positive, dose-response relationship with symptoms of externalizing disorders at independent time points. The findings suggest that prenatal stressful events may be an independent risk factor for offspring externalizing symptoms, regardless of maternal mental health and offspring internalizing.

    Valproate sodium is used for the treatment of epilepsy and other neuropsychiatric disorders in women of childbearing potential. However, there are concerns about impaired cognitive development in children who have been exposed to valproate during pregnancy. To estimate the association between long-term school performance and prenatal exposure to valproate and a number of other antiepileptic drugs (AEDs). In a prospective, population-based cohort study conducted from August 1, 2015, to May 31, 2017, data used in the study were provided by Statistics Denmark on April 15, 2016. All children born alive in Denmark between 1997 and 2006 (n = 656 496) were identified. From this cohort, children who did not participate in the national tests, with presumed coding errors in gestational age and children missing information on their mother's educational level or household income were excluded (n = 177 469) leaving 479 027 children for the analyses. Children were identified and linked across national registers that had information on exposure, covariates, and outcome. The primary outcome was performance in national tests, an academic test taken by students in Danish primary and lower secondary state schools. We assessed performance in Danish and mathematics at different grades among valproate-exposed children and compared their performance with that of unexposed children and children exposed to another AED (lamotrigine). Test scores were standardized to z scores and adjusted for risk factors. Difference in standardized z scores in Danish and mathematics tests among valproate-exposed children compared with unexposed and lamotrigine-exposed children. Of the 656 496 children identified, 479 027 children who participated in the national tests were evaluated, including children exposed to the following AEDs in monotherapy: valproate, 253; phenobarbital, 86; oxcarbazepine, 236; lamotrigine, 396; clonazepam, 188; and carbamazepine, 294.

    Risk factors for urinary tract infection (UTI) in children with prenatal hydronephrosis (PNH) are not clearly defined. Our study aim was to describe incidence and identify factors associated with UTI among a cohort of children diagnosed with PNH. Patients with confirmed PNH from four medical centers were prospectively enrolled in the Society for Fetal Urology (SFU) hydronephrosis registry between 9/2008 and 10/2015. Exclusion criteria included enrollment because of UTI, associated congenital anomalies, and less than 1-month follow-up. Univariate analysis was performed using Fisher's Exact test or Mann-Whitney U. Probability for UTI was determined by Kaplan-Meier curve. Median follow-up was 12 (IQR 4-20) months in 213 patients prenatally diagnosed with hydronephrosis. The majority of the cohort was male (72%), Caucasian (77%), and 26% had high grade (SFU 3 or 4) hydronephrosis. Circumcision was performed in 116/147 (79%) with known status, 19% had vesicoureteral reflux (VUR), and 11% had ureteral dilatation. UTI developed in 8% (n = 18), 89% during their first year of life. Univariate analysis found UTI developed more frequently in females (p hydronephrosis grade nor parenchymal renal cyst to be significant risk factors for UTI development among females. However, hydronephrosis grade and circumcision status were significant risk factors for development of UTI among males (p hydronephrosis. However, we were unable to demonstrate an association between UTI and the use of PA, presence of VUR, dilated ureter, or renal duplication in this observational registry.

    Epidemiological studies of the association between smoking exposure and dental caries are limited. The purpose of this cross-sectional study was to examine the association between prenatal and postnatal secondhand smoke (SHS) exposure and the prevalence of dental caries in primary dentition in young Japanese children. Study subjects were 6412 children aged 3 years. Information on exposure to maternal smoking during pregnancy and postnatal SHS exposure at home was collected via parent questionnaire. Children were classified as having dental caries if one or more primary teeth had decayed or had been filled. Compared with never smoking during pregnancy, maternal smoking in the first trimester of pregnancy was significantly associated with an increased prevalence of dental caries in children (adjusted odds ratio=1.37, 95% confidence interval: 1.03-1.80). Postnatal SHS exposure was also positively associated with dental caries, with a significant positive exposure-response relationship. Compared with children not exposed to prenatal maternal smoking or postnatal SHS at home, those exposed to both prenatal and postnatal smoking had higher odds of dental caries (adjusted odds ratio=1.62, 95% confidence interval: 1.23-2.11). Our findings suggest that maternal smoking during pregnancy and postnatal SHS exposure may be associated with an increased prevalence of dental caries in primary dentition. Copyright © 2015.

    2018-06-01

    Prenatal alcohol exposure (PAE) can be associated with significant difficulties in self-regulatory abilities. As such, interventions have been developed that focus on improving varying aspects of self-regulation for this population. The application of a multilevel theoretical framework that describes the development of self-regulation during early childhood could further advance the field. First, this framework could assist in elucidating mechanisms in the trajectories of early adjustment problems in this population and, second, informing the development of more precise assessment and interventions for those affected by PAE. The aims of the current review were to provide an overview of the self-regulatory framework proposed by Calkins and colleagues (e.g., Calkins, 2007; Calkins and Fox, 2002); examine the self-regulatory difficulties that are commonly experienced during infancy (i.e., 0 to 2 years) and early childhood (i.e., 3 to 8 years) in children with PAE in the context of the developmental framework; and describe how the framework can inform the development of future assessment and intervention provision for young children with PAE. The application of a developmental framework, such as proposed by Calkins and colleagues, allows for a systematic and theoretically driven approach to assessment and intervention programs for young children with PAE.

  9. Protocols on prenatal care for pregnant women with Zika infection and children with microcephaly: nutritional approach

    Directory of Open Access Journals (Sweden)

    Rachel de Sá Barreto Luna Callou Cruz

    Full Text Available Abstract This summary aimed to synthesize the protocol guidelines of Pernambuco, the Ministry of Health and the Centers for Disease Control and Prevention which deal with health care related to Zika virus infection during pregnancy and the preliminary procedures for surveillance on microcephaly cases including nutritional care. With the increase of number of cases on this event since August, 2015, it was necessary to reorganize the prenatal care which is offered to pregnant women, including the protocols in order to reduce the chances of a possible contamination of the virus, to detect previously suspected cases as well as perform follow up on confirmed cases. The gaps in the knowledge of this morbidity, it should be noted that the information and recommendations are subject to revision due to possible incorporation of new knowledge and other evidence, as well as the need for adequacy of surveillance actions in new epidemiological scenarios. It is known that cases of nutritional deficiencies are capable of producing malformation of the Central Nervous System, including microcephaly. In the analysis of the protocols, there were no changes as to the nutritional recommendations already established for the low-risk pregnant women. The authors presented a hypothesis and conceptually, as a prevention measurement, the inclusion of prenatal care to prevent and control isolated or multiple deficiencies associated to microcephaly, such as protein, vitamin A, iodine, folate, B12, vitamin D, biotin, zinc and selenium.

    The main goal of the study was to test the hypothesis that prenatal and postnatal exposures to polycyclic aromatic hydrocarbons (PAH) are associated with depressed lung function in non-asthmatic children. The study sample comprises 195 non-asthmatic children of non-smoking mothers, among whom the prenatal PAH exposure was assessed by personal air monitoring in pregnancy. At the age of 3, residential air monitoring was carried out to evaluate the residential PAH exposure indoors and outdoors. At the age of 5 to 8, children were given allergic skin tests for indoor allergens; and between 5 and 9 years lung function testing (FVC, FEV05, FEV1 and FEF25-75) was performed. The effects of prenatal PAH exposure on lung function tests repeated over the follow-up were adjusted in the General Estimated Equation (GEE) model for the relevant covariates. No association between FVC with prenatal PAH exposure was found; however for the FEV1 deficit associated with higher prenatal PAH exposure (above 37 ng/m(3)) amounted to 53 mL (p=0.050) and the deficit of FEF25-75 reached 164 mL (p=0.013). The corresponding deficits related to postnatal residential indoor PAH level (above 42 ng/m(3)) were 59 mL of FEV1 (p=0.028) and 140 mL of FEF25-75 (p=0.031). At the higher residential outdoor PAH level (above 90 ng/m(3)) slightly greater deficit of FEV1 (71 mL, p=0.009) was observed. The results of the study suggest that transplacental exposure to PAH compromises the normal developmental process of respiratory airways and that this effect is compounded by postnatal PAH exposure.

    The main goal of the study was to test the hypothesis that prenatal and postnatal exposure to polycyclic aromatic hydrocarbons (PAH) is associated with depressed lung function in non-asthmatic children. The study sample comprises 195 non-asthmatic children of non-smoking mothers, among whom the prenatal PAH exposure was assessed by personal air monitoring in pregnancy. At the age of 3, residential air monitoring was carried out to evaluate the residential PAH exposure indoors and outdoors. At the age of 5 to 8, children were given allergic skin tests for indoor allergens; and between 5–9 years lung function testing (FVC, FEV05, FEV1 and FEF25–75) was performed. The effects of prenatal PAH exposure on lung function tests repeated over the follow-up were adjusted in the General Estimated Equation (GEE) model for the relevant covariates. No association between FVC with prenatal PAH exposure was found; however for the FEV1 deficit associated with higher prenatal PAH exposure (above 37ng/m3) amounted to 53 mL (p = 0.050) and the deficit of FEF25–75 reached 164 mL (p=0.013). The corresponding deficits related to postnatal residential indoor PAH level (above 42 ng/m3) were 59 mL of FEV1 (p=0.028) and 140 mL of FEF25–75 (p=0.031). At the higher residential outdoor PAH level (above 90 ng/m3) slightly greater deficit of FEV1 (71mL, p = 0.009) was observed. The results of the study suggest that transplacental exposure to PAH compromises the normal developmental process of respiratory airways and that this effect is compounded by postnatal PAH exposure.

    We prospectively investigated the impact of risk factors for febrile urinary tract infection in infants with postnatally confirmed prenatal hydronephrosis. Patients seen for prenatal hydronephrosis from 2010 to 2013 were prospectively followed. Those with ectopic ureters and ureteroceles, posterior urethral valves and neuropathic bladders were excluded. The primary outcome was febrile catheter specimen urinary tract infection. We performed univariate analysis of 7 a priori risk factors, including age, hydronephrosis grade (low-I or II vs high-III or IV), type (isolated hydronephrosis vs hydroureteronephrosis), continuous antibiotic prophylaxis, vesicoureteral reflux grade, gender and circumcision status. Time to febrile urinary tract infection curves analyzed by Cox proportional regression were generated to adjust for confounders. We collected data on 334 patients, of whom 78% were male. A febrile urinary tract infection developed in 65 patients (19%) at a median of 4 months (range 1 to 31). High grade hydronephrosis was present in 192 infants (57%). Continuous antibiotic prophylaxis was prescribed in 96 cases (29%). Of patients on continuous antibiotic prophylaxis 69% had high grade hydronephrosis. Vesicoureteral reflux was identified in 57 of 238 patients in whom voiding cystourethrogram was done. Reflux was grade I to III in 14 cases and grade IV or V in 43. Two-thirds of the patients with reflux were on continuous antibiotic prophylaxis. Circumcision was performed in 95 males (36%). Cox proportional regression identified female gender (HR 3.3, p = 0.02), uncircumcised males (HR 3.2, p = 0.02), hydroureteronephrosis (HR 10.9, p hydronephrosis was also a significant risk factor (HR 3.0, p = 0.04). After patients with vesicoureteral reflux were excluded from the study, females and uncircumcised males with high grade hydroureteronephrosis had significantly higher febrile urinary tract infection rates. Therefore, those patients may benefit from continuous

    Full Text Available Although speech and language deficits are common in children and strongly associated with poor educational and social outcomes, little attention has been paid to the antecedents. In this study we used the information from the Avon Longitudinal Study of Parents and Children to examine preconception and prenatal environmental risk factors that were related to communication difficulties in children using the Children's Communication Checklist (CCC. We used an exposome-wide approach to identify environmental factors univariably associated with the CCC. Taking account of the False Discovery rate, we used a P value of 0.000157 to identify 621 of 3855 items tested. These were then subjected to a series of stepwise linear regression analyses, firstly within 10 domains: personal characteristics, health, development, education, socio-economic variables, lifestyle, home and social environments, life events and chemical and other exposures; and then with the predictive variables from each domain. The final model consisted of 19 variables independently associated with the communication scale. These variables suggested 6 possible mechanisms: stressors primarily associated with socio-economic disadvantage although other lifestyle choices such as a social network of family or friends can ameliorate these effects; indicators of future parenting skills primarily associated with aspects of parental personality; aspects of the home environment; poor maternal health with a novel finding concerning maternal hearing loss; and maternal education which was partially mediated by the child's IQ. Finally, there may be a mechanism via the maternal diet in pregnancy in particular the consumption of fatty or processed foods. This is the subject of ongoing investigation.

  14. Behavior and Attention Problems in Eight-Year-Old Children with Prenatal Opiate and Poly-Substance Exposure: A Longitudinal Study.

    Egil Nygaard

    Full Text Available Multiple studies have found that children born to mothers with opioid or poly-substance use during pregnancy have more behavior and attention problems and lower cognitive functioning than non-exposed children. The present study aimed to investigate whether behavior and attention problems are more prominent than general cognitive deficits in this risk group and whether the problems wane or increase over time. This prospective longitudinal cross-informant study compared 72 children who were prenatally exposed to heroin and multiple drugs with a group of 58 children without known prenatal risk factors. Group differences in caregivers' and teachers' reports of the children's behavior and attention problems based on the Child Behavior Check List and the ADHD Rating Scale were compared based on group differences in general cognitive functioning at 4 ½ and 8 ½ years of age. Both parent and teacher reports suggest that the exposed group has significantly more problems in several behavioral areas than the comparison group, particularly with regard to attention problems. The preschool teachers had already reported these problems when the children were 4 ½ years old, whereas the caregivers reported these problems mainly when the children were 8 ½ years old. The group differences in behavioral and attentional problems were not significantly greater and some were even significantly smaller than the group differences in general cognitive abilities. These findings suggest that children subject to prenatally drug exposure have increasing problems in multiple areas related to behavior from preschool age to 8 ½ years but that these problems do not seem to be specific; i.e., they are not more severe than the problems with general cognitive abilities found for this group.

    Full Text Available Prenatal diagnosis is the process of determining the health or disease status of the fetus or embryo before birth. The purpose is early detection of diseases and early intervention when required. Prenatal genetic tests comprise of cytogenetic (chromosome assessment and molecular (DNA mutation analysis tests. Prenatal testing enables the early diagnosis of many diseases in risky pregnancies. Furthermore, in the event of a disease, diagnosing prenatally will facilitate the planning of necessary precautions and treatments, both before and after birth. Upon prenatal diagnosis of some diseases, termination of the pregnancy could be possible according to the family's wishes and within the legal frameworks.

    Evidence from the Seychelles Child Development Nutrition Study suggests that maternal nutritional status can modulate the relationship between prenatal methylmercury (MeHg) exposure and developmental outcomes in children. The aim of this study was to investigate whether maternal PUFA status was a confounding factor in any possible associations between prenatal MeHg exposure and developmental outcomes at 5 y of age in the Republic of Seychelles. Maternal status of (n-3) and (n-6) PUFA were measured in serum collected at 28 wk gestation and delivery. Prenatal MeHg exposure was determined in maternal hair collected at delivery. At 5 y of age, the children completed a comprehensive range of sensitive developmental assessments. Complete data from 225 mothers and their children were available for analysis. Multiple linear regression analyses revealed Preschool Language Scale scores of the children improved with increasing maternal serum DHA [22:6(n-3)] concentrations and decreased with increasing arachidonic acid [20:4(n-6)] concentrations, albeit verbal intelligence improved with increasing (n-6) PUFA concentrations in maternal serum. There were no adverse associations between MeHg exposure and developmental outcomes. These findings suggest that higher fish consumption, resulting in higher maternal (n-3) PUFA status, during pregnancy is associated with beneficial developmental effects rather than detrimental effects resulting from the higher concomitant exposures of the fetus to MeHg. The association of maternal (n-3) PUFA status with improved child language development may partially explain the authors' previous finding of improving language scores, as prenatal MeHg exposure increased in an earlier mother-child cohort in the Seychelles where maternal PUFA status was not measured.

    To determine whether prenatal vitamin A and/or Zn supplementation affects postnatal growth. Follow-up of a randomized controlled trial monitoring growth in children from birth up to 24 months of age. Central Java, Indonesia. Children (n 343) of mothers participating in a double-blinded, randomized controlled study of vitamin A and/or Zn supplementation during pregnancy. We report the effects of prenatal supplementation on infant growth, measured as weight-for-age Z-scores (WAZ), height-for-age Z-scores (HAZ) and weight-for-height Z-scores (WHZ ), from 0 to 24 months, as well as differences in growth faltering among the supplementation groups. For HAZ, the absolute differences between the vitamin A-only and vitamin A + Zn groups at 3 and 9 months were 0·34 SD and 0·37 SD, respectively, and the absolute difference between the vitamin A-only and Zn-only groups at 18 months was 0·31 SD. Compared with placebo, none of the supplements affected growth. Defining growth faltering as a downward crossing of two or more major percentile lines, 50-75% of the children were found to be growth faltering within 9 months of age, whereas 17% and 8% scored <-2 SD for WAZ and HAZ, respectively. Prenatal supplementation did not reduce the prevalence of growth faltering. Prenatal vitamin A supplementation had a small but significant effect on postnatal growth of children's length until 18 months of age compared with supplementation with either vitamin A + Zn or Zn alone, but not compared with placebo. It had no effects on other anthropometric measures and did not reduce the prevalence of growth faltering. Future studies should duplicate these findings before recommendations can be made.

    As part of the Avon Longitudinal Study of Parents and Children (ALSPAC), measures of child IQ were collected by trained psychologists. The Wechsler Pre-school and Primary Scale of Intelligence - Revised UK edition (WPPSI) was used at age 4 years in a subsample of children enrolled in ALSPAC (the Children in Focus cohort), chosen at random from the last 6 months of ALSPAC births (about 10% of the participants). At age 8 years all children enrolled in the main cohort were invited to complete a short form of the Wechsler Intelligence Scale for Children (WISC)-III UK . Prenatal blood lead (B-Pb) concentrations were measured by inductively-couple plasma mass spectrometry in samples from women at a median gestation age of 11 weeks. Child blood lead was measured by atomic absorption spectrometry in samples from children attending the Children in Focus clinic at age 30 months. Maternal reports at 32 weeks' gestation were used to generate data on a range of potential confounders. The data were used to determine the associations between prenatal exposure to lead and child IQ at 4 and 8 years. The effect of child B-Pb at 3 years as a moderator of these associations was tested.

    Summer slide, uneven growth of academic skills over the calendar year, captures the fact that the learning gains children make over the school year do not continue at the same pace over the summer, when children are typically not in school. We compared growth of reading skills during the school year and over the summer months in children with pre-or perinatal brain lesion (PL) and typically-developing (TD) children from varying socioeconomic status (SES) backgrounds as a new way to probe the role of structured environmental support in functional plasticity for reading skills in children with PL. Results showed that children with PL performed lower than TD children on both reading decoding and reading comprehension. Group differences were primarily driven by children with larger lesions and children with right hemisphere lesions (RH). For reading comprehension, children with RH showed greater growth during the school year but more slide during the summer months than both TD children and children with left hemisphere lesions, implicating a particularly strong role of structured input in supporting reading comprehension in this group. TD children from lower SES backgrounds fell behind their TD peers from higher SES backgrounds on decoding and reading comprehension, but did not show differential patterns of school year and summer growth. Overall, results highlight the importance of considering the role of a host of factors interacting at multiple levels of analyses, including biological and environmental, in influencing developmental trajectories of typically and atypically-developing children.

    Smoking during pregnancy is common among Inuit women from the Canadian Arctic. Yet prenatal cigarette smoke exposure (PCSE) is seen as a major risk factor for childhood behavior problems. Recent data also suggest that co-exposure to neurotoxic environmental contaminants can exacerbate the effects of PCSE on behavior. This study examined the association between PCSE and behavior at school age in a sample of Inuit children from Nunavik, Québec, where co-exposure to environmental contaminants is also an important issue. Interactions with lead (Pb) and mercury (Hg), two contaminants associated with behavioral problems, were also explored. Participants were 271 children (mean age=11.3years) involved in a prospective birth-cohort study. PCSE was assessed through maternal recall. Assessment of child behavior was obtained from the child's classroom teacher on the Teacher Report Form (TRF) and the Disruptive Behavior Disorders Rating Scale (DBD). Exposure to contaminants was assessed from umbilical cord and child blood samples. Other confounders were documented by maternal interview. After control for contaminants and confounders, PCSE was associated with increased externalizing behaviors and attention problems on the TRF and higher prevalence of attention deficit hyperactivity disorder (ADHD) assessed on the DBD. No interactions were found with contaminants. This study extends the existing empirical evidence linking PCSE to behavioral problems in school-aged children by reporting these effects in a population where tobacco use is normative rather than marginal. Co-exposure to Pb and Hg do not appear to exacerbate tobacco effects, suggesting that these substances act independently. © 2013. Published by Elsevier Inc. All rights reserved.

    Objective: To explore the associations between maternal and prenatal depressive symptoms and children's behavioral problems at 2 years old. Methods: In the present study, a total of 491 mother-child pairs were selected from the Shanghai-Minhang Birth Cohort Study (S-MBCS) which was conducted in Maternal and Child Health Hospital of Minhang District in Shanghai between April and December, 2012. Data from the Center for Epidemiologic Studies on Depression was gathered to assess the maternal depressive symptoms in the second and third trimester of pregnancy, as well as at 6 months and 12 months postpartum. Neurodevelopment at 2 years was assessed, using the Child Behavior Checklist. We used generalized linear models with a log-link function and a Binomial distribution to estimate the risk ratios ( RR s) and 95% CI s, on children's behavioral problems at 2 years of age. Sensitivity analyses were performed among participants without postpartum depressive symptoms. Results: After adjustment on factors as maternal age, gestation week, average monthly income per person, parental education and children's gender etc ., maternal depression in second trimester of pregnancy was found associated with higher risk of both developing emotional ( RR =2.61, 95% CI : 1.36-4.99) and internalizing problems ( RR =1.94, 95% CI : 1.22-3.08). However, maternal depression in third trimester was found to be associated with higher risks of developing emotional ( RR =6.46, 95% CI : 3.09-13.53), withdrawn ( RR =2.42, 95% CI : 1.16-5.02), aggressive ( RR =2.93, 95% CI : 1.45-5.94), internalizing ( RR =1.79, 95% CI : 1.01-3.16) or externalizing problems ( RR =2.56, 95% CI :1.49-4.42). In sensitivity analysis, antenatal maternal depression was found positively associated with children's emotional, internalizing and externalizing problems and the differences all statistically significant. Conclusions: Maternal depression during pregnancy might increase the risks of children's behavioral problems. In

    In this prospective cohort study of Caucasian mothers and children in Krakow, Poland, we evaluated the role of prenatal exposure to urban air pollutants in the pathogenesis of neurobehavioral disorders. The objective of this study was to investigate the relationship between prenatal polycyclic aromatic hydrocarbon (PAH) exposure and child intelligence at 5 years of age, controlling for potential confounders suspected to play a role in neurodevelopment. A cohort of pregnant, healthy, nonsmoking women was enrolled in Krakow, Poland, between 2001 and 2006. During pregnancy, participants were invited to complete a questionnaire and undergo 48-hr personal air monitoring to estimate their babies' exposure, and to provide a blood sample and/or a cord blood sample at the time of delivery. Two hundred fourteen children were followed through 5 years of age, when their nonverbal reasoning ability was assessed using the Raven Coloured Progressive Matrices (RCPM). We found that higher (above the median of 17.96 ng/m3) prenatal exposure to airborne PAHs (range, 1.8-272.2 ng/m3) was associated with decreased RCPM scores at 5 years of age, after adjusting for potential confounding variables (n = 214). Further adjusting for maternal intelligence, lead, or dietary PAHs did not alter this association. The reduction in RCPM score associated with high airborne PAH exposure corresponded to an estimated average decrease of 3.8 IQ points. These results suggest that prenatal exposure to airborne PAHs adversely affects children's cognitive development by 5 years of age, with potential implications for school performance. They are consistent with a recent finding in a parallel cohort in New York City.

    The 2002 "unborn child ruling" resulted in State Children's Health Insurance Program (SCHIP) expansion for states to cover prenatal care for low-income women without health insurance. Foreign-born Latinas who do not qualify for Medicaid coverage theoretically should have benefited most from the policy ruling given their documented low rates of prenatal care utilization. This study compares prenatal care utilization and subsequent birth outcomes among foreign-born Latinas in six states that used the unborn child ruling to expand coverage to those in ten states that did not implement the expansion. This policy analysis examines cross-sectional pooled US natality data from the pre-enactment years (2000-2003) versus post-enactment years (2004-2007) to estimate the effect of the UCR on prenatal care utilization and birth outcome measures for foreign-born Latinas. Then using a difference-in-difference estimator, we assessed these differences across time for states that did or did not enact the unborn child ruling. Analyses were then replicated on a high-risk subset of the population (single foreign-born Latinas with lower levels of education). The SCHIP unborn child ruling policy expansion increased PNCU over time in the six enacting states. Foreign-born Latinas in expansion enacting states experienced increases in prenatal care utilization though only the high-risk subset were statistically significant. Birth outcomes did not change. The SCHIP unborn child ruling policy was associated with enhanced PNC for a subset of high-risk foreign-born Latinas.

    This study examines the association between expectant parents' psychological distress and children's development at 36 months old. This is a prospective population study based on the Norwegian Mother and Child Cohort Study, N = 31,663. Logistic regression models were used to assess whether high scores (cutoff ≥ 2.00) on the symptom checklist-5 in parents predicted higher levels (cutoff ≥ 90 percentile) of developmental problems in their children. The risk of emotional and behavioral problems were significantly increased in children when both parents were affected by psychological distress during pregnancy, fully adjusted OR 2.35 (95% CI 1.36, 4.07) and OR 2.65 (96% CI 1.564.48), respectively. The risk was higher when mothers reported high level of psychological distress than when only the fathers did, but the risk of emotional difficulties in children was highest when both parents presented high levels of psychological distress, indicating an additive effect of parental psychological distress.

    Environmental pollutants such as polycyclic aromatic hydrocarbons (PAHs), lead, and mercury are released by combustion of coal and other fossil fuels. In the present study we evaluated the association between prenatal exposure to these pollutants and child development measured by the Gesell Developmental Schedules at 2 years of age. The study was conducted in Tongliang, Chongqing, China, where a seasonally operated coal-fired power plant was the major source of ambient PAHs and also contributed lead and mercury to the air. In a cohort of nonsmoking women and their newborns enrolled between March 2002 and June 2002, we measured levels of PAH-DNA adducts, lead, and mercury in umbilical cord blood. PAH-DNA adducts (specifically benzo(a)pyrene adducts) provided a biologically relevant measure of PAH exposure. We also obtained developmental quotients (DQs) in motor, adaptive, language, and social areas. Decrements in one or more DQs were significantly associated with cord blood levels of PAH-DNA adducts and lead, but not mercury. Increased adduct levels were associated with decreased motor area DQ (p = 0.043), language area DQ (p = 0.059), and average DQ (p = 0.047) after adjusting for cord lead level, environmental tobacco smoke, sex, gestational age, and maternal education. In the same model, high cord blood lead level was significantly associated with decreased social area DQ (p = 0.009) and average DQ (p = 0.038). The findings indicate that exposure to pollutants from the power plant adversely affected the development of children living in Tongliang.

    Fish contain nutrients essential to the developing fetal brain, but they are contaminated with methylmercury. The Tohoku Study of Child Development, now underway in the Sanriku coastal area of Miyagi prefecture, Japan, follows mother-child pairs to examine the risks and benefits of fish consumption during pregnancy, especially the effects of prenatal exposures to methylmercury, selenium, and docosahexaenoic acid (DHA) on child neurodevelopment. Children aged 18 months were administered the Bayley Scales of Infant Development second edition (BSID-II) and Kyoto Scale of Psychological Development (KSPD) in 2004-2008. Complete data of cord-blood total mercury (THg), cord-plasma selenium, maternal-plasma DHA, the above test scores, and confounders for 566 mother-child pairs were available. The median cord-blood THg level was 15.7 (range, 2.7-96.1) ng/g. Since the BSID-II and KSPD scores were significantly lower in the 285 boys than in the 281 girls, analyses were conducted separately. The Psychomotor Development Index (PDI) of BSID-II was significantly correlated with cord-blood THg only in the boys, and significance of the association remained unchanged after adjusting for possible confounders; i.e., a 10-fold increase in cord-blood THg was associated with a 8.3-point decrease in the score of the PDI. Other significant correlations of THg were not seen in the boys or girls. Selenium and DHA showed no significant correlations with the BSID-II or KSPD scores in either sex. In conclusion, intrauterine methylmercury exposure may affect psychomotor development, and boys appear to be more vulnerable to the exposure than girls.

    BackgroundEarlier identification of children with prenatal alcohol exposure (PAE) remains a challenge. The objective of this study was to identify neurobehavioral (NB) outcomes associated with PAE in infants.MethodsThis manuscript evaluates NB outcomes at 6.33±1.12 months of age in 93 infants (39 PAE and 54 No-PAE) recruited prospectively into the ENRICH cohort. PAE was assessed by prospective repeated TLFB interviews and a panel of ethanol biomarkers. NB outcomes were evaluated by the Bayley Scales of Infant Development (BSID-III), Parenting Stress Index (PSI), Infant Behavior Questionnaire (IBQ-R), and Infant Sensory Profile (ISP).ResultsMean maternal age at enrollment was 28.18±5.75, and 64.52% were Hispanic/Latina. Across three TLFB calendars, absolute alcohol per day in the PAE group was 0.44±0.72, corresponding to low-moderate alcohol consumption. While no association was observed between PAE and BSID-III (P's>0.05), PAE was associated with higher scores on the PSI difficult child scale (=13.9; P=0.015), total stress (=13.9; P=0.010), and IBQ negative affect (=8.60; P=0.008) measures after adjustment for covariates.ConclusionsCaregiver-reported assessments may provide a currently unrecognized opportunity to identify behavioral deficits, point to early interventions, and should be included in clinical assessments of infants at-risk for fetal alcohol spectrum disorder.Pediatric Research advance online publication, 16 May 2018; doi:10.1038/pr.2018.26.

    Our previous study demonstrated that prenatal manganese exposure is associated with cognitive test scores among a cohort of 2- to 3-year-old Bangladeshi children. This study tested the hypothesis that the adverse effects of manganese are mediated through poor prenatal growth. Pregnant mothers were enrolled in a birth cohort in Bangladesh between 2008 and 2011, and children were followed at birth and age 20-40 months. Manganese concentration was measured in umbilical cord blood. Anthropometric measurements (weight, length, head circumference) were assessed at delivery. Children's cognitive development was assessed at age 20-40 months using the Bayley Scales of Infant and Toddler Development-Third Edition. Using recently developed statistical approaches that estimate mediation and interaction effects simultaneously, we evaluated whether the association between cord blood manganese and cognitive score was mediated through anthropometric measures at birth. This analysis included 764 mother-child pairs. Higher manganese concentration was associated with lower cognitive score [β=-0.61, standard error (SE)=0.23, p = 0.009]. Among the birth measures, we found a significant indirect effect only through birth length (β =-0.10, SE = 0.03, p = 0.001). We also found evidence of mediated interaction (both mediation and interaction, β =-0.03, SE = 0.01, p = 0.01) with birth length in the association between cord blood manganese and cognitive score. The overall proportion mediated by birth length was 33% (p = 0.02) and the proportion attributed to interaction was 11% (p = 0.04). We did not find evidence of a mediating effect through birth weight or head circumference. Our findings confirm that prenatal growth, particularly birth length, contributes to the overall effect of environmental manganese exposure on a child's cognitive development.

    Despite accumulating evidence from animal models demonstrating that prenatal alcohol exposure (PAE) results in life-long neuroendocrine dysregulation, very little is known on this topic among humans with fetal alcohol spectrum disorders (FASD). We expected that alterations in gonadal hormones might interfere with the typical development of white matter (WM) myelination, and in a sex-dependent manner, in human adolescents with FASD. In order to investigate this hypothesis, we used diffusion tensor imaging (DTI) to assess: 1) whether or not sex moderates the impact of PAE on WM microstructure; and 2) how gonadal hormones relate to alterations in WM microstructure in children and adolescents affected by PAE. 61 youth (9 to 16 yrs.; 49% girls; 50% PAE) participated as part of the Collaborative Initiative on Fetal Alcohol Spectrum Disorders (CIFASD). DTI scans and passive drool samples were obtained to examine neurodevelopmental associations with testosterone (T) and dehydroepiandrosterone (DHEA) levels in boys and girls, and estradiol (E2) and progesterone (P) levels in girls. Tract-based spatial statistics were utilized to generate fractional anisotropy (FA) and mean diffusivity (MD) for 9 a priori WM regions of interest (ROIs). As predicted, alterations in FA were observed in adolescents with PAE relative to controls, and these differences varied by sex. Girls with PAE exhibited lower FA (Inferior fronto-occipital and Uncinate fasciculi) while boys with PAE exhibited higher FA (Callosal body, Cingulum, Corticospinal tract, Optic radiation, Superior longitudinal fasciculus) relative to age-matched controls. When gonadal hormone levels were examined in relation to DTI measures, additional group differences in FA were revealed, demonstrating that neuroendocrine factors are associated with PAE-related brain alterations. These findings provide human evidence that PAE relates to sex-specific differences in WM microstructure, and underlying alterations in gonadal hormone

    Full Text Available Objectives: The main goal of the study was to assess possible association between fetal exposure to fi ne particulate matter (PM2.5 and exhaled carbon monoxide (eCO measured in non-asthmatic children. Material and Methods: The subjects include 118 children taking part in an ongoing population-based birth cohort study in Kraków. Personal samplers of PM2.5 were used to measure fi ne particle mass in the fetal period and carbon monoxide (CO in exhaled breath from a single exhalation effort at the age of 7. In the statistical analysis of the effect of prenatal PM2.5 exposure on eCO, a set of potential confounders, such as environmental tobacco smoke (ETS, city residence area, sensitization to house dust allergens and the occurrence of respiratory symptoms monitored over the seven-year follow-up was considered. Results: The level of eCO did not correlate with the self-reported ETS exposure recorded over the follow-up, however, there was a positive signifi cant relationship with the prenatal PM2.5 exposure (non-parametric trend p = 0.042. The eCO mean level was higher in atopic children (geometric mean = 2.06 ppm, 95% CI: 1.58–2.66 ppm than in non-atopic ones (geometric mean = 1.57 ppm, 95% CI: 1.47–1.73 ppm and the difference was statistically signifi cant (p = 0.036. As for the respiratory symptoms, eCO values were associated positively only with the cough severity score recorded in the follow-up (nonparametric trend p = 0.057. In the nested multivariable linear regression model, only the effects of prenatal PM2.5 and cough severity recorded in the follow-up were related to eCO level. The prenatal PM2.5 exposure represented 5.1%, while children’s cough represented only 2.6% of the eCO variability. Conclusion: Our study suggests that elevated eCO in non-asthmatic children may result from oxidative stress experienced in the fetal period and that heme oxygenase (HO activity in body tissues may be programmed in the fetal period by the exposure to

    Fetal alcohol spectrum disorders (FASD) are characterized by impairment in cognitive function that may or may not be accompanied by craniofacial anomalies, microcephaly, and/or growth retardation. Resting-state functional MRI (rs-fMRI), which examines the low-frequency component of the blood oxygen level dependent (BOLD) signal in the absence of an explicit task, provides an efficient and powerful mechanism for studying functional brain networks even in low-functioning and young subjects. Studies using independent component analysis (ICA) have identified a set of resting-state networks (RSNs) that have been linked to distinct domains of cognitive and perceptual function, which are believed to reflect the intrinsic functional architecture of the brain. This study is the first to examine resting-state functional connectivity within these RSNs in FASD. Rs-fMRI scans were performed on 38 children with FASD (19 with either full fetal alcohol syndrome (FAS) or partial FAS (PFAS), 19 nonsyndromal heavily exposed (HE)), and 19 controls, mean age 11.3 ± 0.9 years, from the Cape Town Longitudinal Cohort. Nine resting-state networks were generated by ICA. Voxelwise group comparison between a combined FAS/PFAS group and controls revealed localized dose-dependent functional connectivity reductions in five regions in separate networks: anterior default mode, salience, ventral and dorsal attention, and R executive control. The former three also showed lower connectivity in the HE group. Gray matter connectivity deficits in four of the five networks appear to be related to deficits in white matter tracts that provide intra-RSN connections.

    Full Text Available Prenatal sex hormones can induce abnormalities in the reproductive system and adversely impact on genital development. We investigated whether sex hormones in cord blood influenced the ratio of the second to fourth digit lengths (2D/4D in school-aged children. Of the 514 children who participated in a prospective cohort study on birth in Sapporo between 2002 and 2005, the following sex hormone levels were measured in 294 stored cord blood samples (135 boys and 159 girls; testosterone (T, estradiol (E, progesterone, LH, FSH, inhibin B, and insulin-like factor 3 (INSL3. A total of 350 children, who were of school age and could be contacted for this survey, were then requested via mail to send black-and-white photocopies of the palms of both the left and right hands. 2D/4D was calculated in 190 children (88 boys and 102 girls using photocopies and derived from participants with the characteristics of older mothers, a higher annual household income, higher educational level, and fewer smokers among family members. 2D/4D was significantly lower in males than in females (p<0.01. In the 294 stored cord blood samples, T, T/E, LH, FSH, Inhibin B, and INSL3 levels were significantly higher in samples collected from males than those from females. A multivariate regression model revealed that 2D/4D negatively correlated with INSL3 in males and was significantly higher in males with <0.32 ng/mL of INSL3 (p<0.01. No correlations were observed between other hormones and 2D/4D. In conclusion, 2D/4D in school-aged children, which was significantly lower in males than in females, was affected by prenatal Leydig cell function.

    Only 60–70% of fertilized eggs may result in a live birth, and very early fetal loss mainly goes unnoticed. Outcomes that can only be ascertained in live-born children will be missing for those who do not survive till birth. In this article, we illustrate a common bias structure (leading to ‘live-birth bias’) that arises from studying the effects of prenatal exposure to environmental factors on long-term health outcomes among live births only in pregnancy cohorts. To illustrate this we used prenatal exposure to perfluoroalkyl substances (PFAS) and attention-deficit/hyperactivity disorder (ADHD) in school-aged children as an example. PFAS are persistent organic pollutants that may impact human fecundity and be toxic for neurodevelopment. We simulated several hypothetical scenarios based on characteristics from the Danish National Birth Cohort and found that a weak inverse association may appear even if PFAS do not cause ADHD but have a considerable effect on fetal survival. The magnitude of the negative bias was generally small, and adjusting for common causes of the outcome and fetal loss can reduce the bias. Our example highlights the need to identify the determinants of pregnancy loss and the importance of quantifying bias arising from conditioning on live birth in observational studies. PMID:25604449

    Prenatal cocaine exposure (PCE) in humans and animals has been shown to impair social development. Molecules that mediate synaptic plasticity and learning in the medial prefrontal cortex (mPFC), specifically brain-derived neurotrophic factor (BDNF) and its downstream signaling molecule, early growth response protein 1 (egr1), have been shown to affect the regulation of social interactions (SI). In this study we determined the effects of PCE on SI and the corresponding ultrasonic vocalizations (USVs) in developing mice. Furthermore, we studied the PCE-induced changes in the constitutive expression of BDNF, egr1 and their transcriptional regulators in the mPFC as a possible molecular mechanism mediating the altered SI. In prenatal cocaine-exposed (PCOC) mice we identified increased SI and USV production at postnatal day (PD) 25, and increased SI but not USVs at PD35. By PD45 the expression of both social behaviors normalized in PCOC mice. At the molecular level, we found increased BDNF exon IV and egr1 mRNA in the mPFC of PCOC mice at PD30 that normalized by PD45. This was concurrent with increased EGR1 protein in the mPFC of PCOC mice at PD30, suggesting a role of egr1 in the enhanced SI observed in juvenile PCOC mice. Additionally, by measuring the association of acetylation of histone 3 at lysine residues 9 and 14 (acH3K9,14) and MeCP2 at the promoters of BDNF exons I and IV and egr1, our results provide evidence of promoter-specific alterations in the mPFC of PCOC juvenile mice, with increased association of acH3K9,14 only at the BDNF exon IV promoter. These results identify a potential PCE-induced molecular alteration as the underlying neurobiological mechanism mediating the altered social development in juvenile mice. © 2014 S. Karger AG, Basel.

    Polychlorinated biphenyls (PCBs), organochlorine pesticides, and methylmercury (MeHg) are environmentally persistent with adverse effects on neurodevelopment. However, especially among populations with commonly experienced low levels of exposure, research on neurodevelopmental effects of these toxicants has produced conflicting results. We assessed the association of low-level prenatal exposure to these contaminants with memory and learning. We studied 393 children, born between 1993 and 1998 to mothers residing near a PCB-contaminated harbor in New Bedford, Massachusetts. Cord serum PCB, DDE (dichlorodiphenyldichloroethylene), and maternal peripartum hair mercury (Hg) levels were measured to estimate prenatal exposure. Memory and learning were assessed at 8 years of age (range, 7-11 years) using the Wide Range Assessment of Memory and Learning (WRAML), age-standardized to a mean ± SD of 100 ± 15. Associations with each WRAML index-Visual Memory, Verbal Memory, and Learning-were examined with multivariable linear regression, controlling for potential confounders. Although cord serum PCB levels were low (sum of four PCBs: mean, 0.3 ng/g serum; range, 0.01-4.4), hair Hg levels were typical of the U.S. fish-eating population (mean, 0.6 μg/g; range, 0.3-5.1). In multivariable models, each microgram per gram increase in hair Hg was associated with, on average, decrements of -2.8 on Visual Memory (95% CI: -5.0, -0.6, p = 0.01), -2.2 on Learning (95% CI: -4.6, 0.2, p = 0.08), and -1.7 on Verbal Memory (95% CI: -3.9, 0.6, p = 0.14). There were no significant adverse associations of PCBs or DDE with WRAML indices. These results support an adverse relationship between low-level prenatal MeHg exposure and childhood memory and learning, particularly visual memory.

    adverse maternal and child outcomes that are important in their own right, but that also have significant implications for the development of criminal behavior. This paper summarizes a three-decade program of research that has attempted to improve the health and development of mothers and infants and their future life prospects with prenatal and infancy home visiting by nurses. The program, known as the Nurse-Family Partnership, is designed for low-income mothers who have had no previous live births. The home visiting nurses have three major goals: to improve the outcomes of pregnancy by helping women improve their prenatal health; to improve the child’s health and development by helping parents provide more sensitive and competent care of the child; and to improve parental life-course by helping parents plan future pregnancies, complete their educations, and find work. Given consistent effects on prenatal health behaviors, parental care of the child, child abuse and neglect, child health and development, maternal life-course, and criminal involvement of the mothers and children, the program is now being offered for public investment throughout the United States, where careful attention is being given to ensuring that the program is being conducted in accordance with the program model tested in the randomized trials. The program also is being adapted, developed, and tested in countries outside of the US: the Netherlands, England, Scotland, Northern Ireland, Australia, and Canada, as well as Native American and Alaskan Native populations in the US, where programmatic adjustments are being made to accommodate different populations served and health and human service contexts. We believe it is important to test this program in randomized controlled trials in these new settings before it is offered for public investment.

    Trisomy 13 and trisomy 18 (T13-18) are associated with high rates of perinatal death and with severe disability among survivors. Prenatal diagnosis (PND) may lead many women to terminate their pregnancy but some women choose to continue their pregnancy. We sent 503 invitations to answer a questionnaire to parents who belong to T13 and 18 internet support groups. Using mixed methods, we asked parents about their prenatal experience, their hopes, the life of their affected child, and their family experience. 332 parents answered questions about 272 children; 128 experienced PND. These parents, despite feeling pressure to terminate (61%) and being told that their baby would likely die before birth (94%), chose to continue the pregnancy. Their reasons included: moral beliefs (68%), child-centered reasons (64%), religious beliefs (48%), parent-centered reasons (28%), and practical reasons (6%). At the time of the diagnosis, most of these parents (80%) hoped to meet their child alive. By the time of birth, 25% chose a plan of full interventions. A choice of interventions at birth was associated with fewer major anomalies (P Parents describe "Special" healthcare providers as those who gave balanced and personalized information, respected their choice, and provided support.

    Many children in the remote Fitzroy Valley region of Western Australia have prenatal alcohol exposure (PAE). Individuals with PAE can have neurodevelopmental impairments and be diagnosed with one of several types of Fetal Alcohol Spectrum Disorder (FASD). Fine motor skills can be impaired by PAE, but no studies have developed a comprehensive profile of fine motor skills in a population-based cohort of children with FASD. We aimed to develop a comprehensive profile of fine motor skills in a cohort of Western Australian children; determine whether these differed in children with PAE or FASD; and establish the prevalence of impairment. Children (n = 108, 7 to 9 years) were participants in a population-prevalence study of FASD in Western Australia. Fine motor skills were assessed using the Bruininks-Oseretsky Test of Motor Proficiency, which provided a Fine Motor Composite score, and evaluated Fine Manual Control (Fine Motor Precision; Fine Motor Integration) and Manual Coordination (Manual Dexterity; Upper-Limb Coordination). Descriptive statistics were reported for the overall cohort; and comparisons made between children with and without PAE and/or FASD. The prevalence of severe (≤ 2nd percentile) and moderate (≤16th percentile) impairments was determined. Overall, Fine Motor Composite scores were 'average' (M = 48.6 ± 7.4), as were Manual Coordination (M = 55.7 ± 7.9) and Fine Manual Control scores (M = 42.5 ± 6.2). Children with FASD had significantly lower Fine Motor Composite (M = 45.2 ± 7.7 p = 0.046) and Manual Coordination scores (M = 51.8 ± 7.3, p = 0.027) than children without PAE (Fine Motor Composite M = 49.8 ± 7.2; Manual Coordination M = 57.0 ± 7.7). Few children had severe impairment, but rates of moderate impairment were very high. Different types of fine motor skills should be evaluated in children with PAE or FASD.

    Studies have reported some evidence of adverse effects of organochlorine exposures on child development, but the results have been inconsistent, and few studies have evaluated associations with child behavior. We investigated the association between prenatal and early-life exposures to 2,2',4,4',5,5'-hexachlorobiphenyl (PCB-153) and 1,1-dichloro-2,2-bis( p -chlorophenyl)-ethylene ( p,p '-DDE) and behaviors in children between 5 and 9 y of age. In the Biopersistent organochlorines in diet and human fertility: Epidemiologic studies of time to pregnancy and semen quality in Inuit and European populations (INUENDO) cohort, consisting of mother-child pairs from Greenland and Ukraine ( n =1,018), maternal serum PCB-153 and p,p '-DDE concentrations were measured during pregnancy, and cumulative postnatal exposures during the first 12 months after delivery were estimated using a pharmacokinetic model. Parents completed the Strengths and Difficulties Questionnaire (SDQ), and children's behaviors were dichotomized as abnormal (high) versus normal/borderline for five SDQ subscales and the total difficulties score. The total difficulties score, an overall measure of abnormal behavior, was not clearly associated with pre- or postnatal exposures to PCB-153 or to p,p '-DDE. However, pooled adjusted odds ratios (ORs) for high conduct problem scores with a doubling of exposure were 1.19 (95% CI: 0.99, 1.42) and 1.16 (95% CI: 0.96, 1.41) for pre- and postnatal PCB-153, respectively, and 1.25 (95% CI: 1.04, 1.51) and 1.24 (95% CI: 1.01, 1.51) for pre- and postnatal p,p '-DDE, respectively. Corresponding ORs for high hyperactivity scores were 1.24 (95% CI: 0.94, 1.62) and 1.08 (95% CI: 0.81, 1.45) for pre- and postnatal PCB-153, respectively, and 1.43 (95% CI: 1.06, 1.92) and 1.27 (95% CI: 0.93, 1.73) for pre- and postnatal p,p '-DDE, respectively.

    To identify postnatal predictors of malnutrition among 7- to 10-year-old children and to assess the long-term effects of antenatal micronutrient supplementation on malnutrition. A follow-up study was conducted to assess the nutritional status of 7- to 10-year-olds (1747 children) whose mothers participated in a cluster-randomized double-blind controlled trial from 2002 to 2006. The rate of malnourished 7- to 10-year-olds was 11.1%. A mixed-effects logistic regression model adjusted for the cluster-sampling design indicated that mothers with low prepregnant midupper arm circumference had boys with an increased risk of thinness (aOR  2.05, 95% CI  1.11, 3.79) and girls who were more likely to be underweight (aOR 2.01, 95% CI 1.05, 3.85). Antenatal micronutrient supplementation was not significantly associated with malnutrition. Low birth weight was significantly associated with increased odds of malnutrition among boys (aOR 4.34, 95% CI 1.82, 10.39) and girls (aOR  7.50, 95% CI 3.48, 16.13). Being small for gestational age significantly increased the odds of malnutrition among boys (aOR 1.75, 95% CI 1.01, 3.04) and girls (aOR 4.20, 95% CI  2.39, 7.39). In addition, household wealth, parental height, being picky eater, and illness frequency also predicted malnutrition. Both maternal prenatal nutrition and adverse birth outcomes are strong predictors of malnutrition among early school-aged children. Currently, available evidence is insufficient to support long-term effects of antenatal micronutrient supplementation on children's nutrition. www.isrctn.com: ISRCTN08850194.

    The American Urological Association established the Vesicoureteral Reflux Guideline Update Committee in July 2005 to update the management of primary vesicoureteral reflux in children guideline. The Panel defined the task into 5 topics pertaining to specific vesicoureteral reflux management issues, which correspond to the management of 3 distinct index patients and the screening of 2 distinct index patients. This report summarizes the existing evidence pertaining to screening of siblings and offspring of index patients with vesicoureteral reflux and infants with prenatal hydronephrosis. From this evidence clinical practice guidelines are developed to manage the clinical scenarios insofar as the data permit. The Panel searched the MEDLINE(R) database from 1994 to 2008 for all relevant articles dealing with the 5 chosen guideline topics. The database was reviewed and each abstract segregated into a specific topic area. Exclusions were case reports, basic science, secondary reflux, review articles and not relevant. The extracted article to be accepted should have assessed a cohort of children, clearly stating the number of children undergoing screening for vesicoureteral reflux. Vesicoureteral reflux should have been diagnosed with a cystogram and renal outcomes assessed by nuclear scintigraphy. The screening articles were extracted into data tables developed to evaluate epidemiological factors, patient and renal outcomes, and results of treatment. The reporting of meta-analysis of observational studies elaborated by the MOOSE group was followed. The extracted data were analyzed and formulated into evidence-based recommendations regarding the screening of siblings and offspring in index cases with vesicoureteral reflux and infants with prenatal hydronephrosis. In screened populations the prevalence of vesicoureteral reflux is 27.4% in siblings and 35.7% in offspring. Prevalence decreases at a rate of 1 screened person every 3 months of age. The prevalence is the same

    2017-06-01

    Patients participating in group prenatal care gather together with women of similar gestational ages and 2 providers who cofacilitate an educational session after a brief medical assessment. The model was first described in the 1990s by a midwife for low-risk patients and is now practiced by midwives and physicians for both low-risk patients and some high-risk patients, such as those with diabetes. The majority of literature on group prenatal care uses CenteringPregnancy, the most popular model. The first randomized controlled trial of CenteringPregnancy showed that it reduced the risk of preterm birth in low-risk women. However, recent meta-analyses have shown similar rates of preterm birth, low birthweight, and neonatal intensive care unit admission between women participating in group prenatal care and individual prenatal care. There may be subgroups, such as African Americans, who benefit from this type of prenatal care with significantly lower rates of preterm birth. Group prenatal care seems to result in increased patient satisfaction and knowledge and use of postpartum family planning as well as improved weight gain parameters. The literature is inconclusive regarding breast-feeding, stress, depression, and positive health behaviors, although it is theorized that group prenatal care positively affects these outcomes. It is unclear whether group prenatal care results in cost savings, although it may in large-volume practices if each group consists of approximately 8-10 women. Group prenatal care requires a significant paradigm shift. It can be difficult to implement and sustain. More randomized trials are needed to ascertain the true benefits of the model, best practices for implementation, and subgroups who may benefit most from this innovative way to provide prenatal care. In short, group prenatal care is an innovative and promising model with comparable pregnancy outcomes to individual prenatal care in the general population and improved outcomes in some

    Objectives. We used a geographic information system and cluster analyses to determine locations in need of enhanced Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) Program services. Methods. We linked documented births in the 2010 California Birth Statistical Master File with the 2010 data from the WIC Integrated Statewide Information System. Analyses focused on the density of pregnant women who were eligible for but not receiving WIC services in California’s 7049 census tracts. We used incremental spatial autocorrelation and hot spot analyses to identify clusters of WIC-eligible nonparticipants. Results. We detected clusters of census tracts with higher-than-expected densities, compared with the state mean density of WIC-eligible nonparticipants, in 21 of 58 (36.2%) California counties (P Hot spot analyses provided a rigorous and objective approach to determine the locations of statistically significant clusters of WIC-eligible nonparticipants. Results helped inform WIC program and funding decisions, including the opening of new WIC centers, and offered a novel approach for targeting public health services. PMID:24354821

    To review the scientific evidence for prenatal programming of childhood overweight and obesity, and discuss its implications for MCH research, practice, and policy. A systematic review of observational studies examining the relationship between prenatal exposures and childhood overweight and obesity was conducted using MOOSE guidelines. The review included literature posted on PubMed and MDConsult and published between January 1975 and December 2005. Prenatal exposures to maternal diabetes, malnutrition, and cigarette smoking were examined, and primary study outcome was childhood overweight or obesity as measured by body mass index (BMI) for children ages 5 to 21. Four of six included studies of prenatal exposure to maternal diabetes found higher prevalence of childhood overweight or obesity among offspring of diabetic mothers, with the highest quality study reporting an odds ratio of adolescent overweight of 1.4 (95% CI 1.0-1.9). The Dutch famine study found that exposure to maternal malnutrition in early, but not late, gestation was associated with increased odds of childhood obesity (OR 1.9, 95% CI 1.5-2.4). All eight included studies of prenatal exposure to maternal smoking showed significantly increased odds of childhood overweight and obesity, with most odds ratios clustering around 1.5 to 2.0. The biological mechanisms mediating these relationships are unknown but may be partially related to programming of insulin, leptin, and glucocorticoid resistance in utero. Our review supports prenatal programming of childhood overweight and obesity. MCH research, practice, and policy need to consider the prenatal period a window of opportunity for obesity prevention.

    Full Text Available Introduction. Lissencephaly (“smooth brain” forms a major group of brain malformations due to abnormal neuronal migration. It can cause severe intellectual and motor disability and epilepsy in children. The prenatal diagnosis of this malformation is rare. Case report. We presented a case of the prenatal diagnosis of lissencephaly. A 30-year old pregnant woman was reffered to the hospital at the week 35 of gestation for magnetic resonance imaging (MRI after an ultrasound examination demonstrated fetal cerebral ventriculomegaly. Fetal MRI of the brain showed “smooth”, agyrya cortex. The female infant was born at term with birth weight of 2,500 g and Apgar score 8, showing global developmental delay. Postnatal ultrasound and MRI confirmed classical lissencephaly. She is now 8 years old and has spastic quadriparesis, mental retardation and epilepsy. Conclusion. Confirmation of the ultrasound diagnosis with MRI is desirable for the prenatal diagnosis of lissencephaly.

  2. Robustness of estimation of differential renal function in infants and children with unilateral prenatal diagnosis of a hydronephrotic kidney on dynamic renography: How real is the supranormal kidney?

    The two methods recommended for estimation of differential renal function (DRF) in the renography guidelines published by the European Association of Nuclear Medicine are the area under the background-subtracted time-activity curves (AUCs) (often called the integral method) and the regression slope of the background-subtracted Rutland/Patlak plot analysis. The current study investigated the agreement/disagreement of DRF estimations obtained using these two techniques. This report also focusses on the occurrence of supranormal function of the affected kidney (defined as DRF >55%) and reviews the related technical and physiological factors. A total of 394 renographic studies in 101 children with a prenatal diagnosis of unilateral renal pelvic dilatation confirmed on postnatal studies were retrieved from optical disc and reprocessed by one author. DRF was calculated using the Rutland/Patlak plot and the AUC over the time period 40-120 s following an injection of{sup 99m}Tc-mercaptoacetyltriglycine. The difference in DRF between the methods (Rutland/Patlak minus AUC) and 95% limits of agreement were calculated. The age distribution of the difference between the methods was also analysed. For all 394 measurements the mean difference was -0.8% (range -21.0% to 16.9%, SD 3.9%). The 95% limits of agreement were -7.0% to 8.6%. Analysis of the data revealed that greater spread of DRF between the techniques was seen in studies performed at a younger age: a discrepancy of >5% DRF was significantly more common in those <1 year of age than in those >1 year old (25.3% vs 9.9%; chi-square, p<0.0005). Supranormal function was found less frequently using the Rutland/Patlak method than with the AUC method (8.4% vs 11.2%; chi-square, p<0.0005). The frequency of this diagnosis was reduced to 4.6% when both methods were required to be in agreement. (orig.)

As we show, these terms have different meanings, and we...... examine definitions of the relevant concepts in order to illustrate this point. The concepts are i) prenatal, ii) genetic screening, iii) screening, scanning and testing, iv) maternal and foetal tests, v) test techniques and vi) genetic conditions. So far, prenatal screening has little connection...... with precisely defined genetics. There are benefits but also disadvantages in overstating current links between them in the term genetic screening. Policy making and professional and public understandings about screening could be clarified if the distinct meanings of prenatal screening and genetic screening were...

    South Africa carries a high burden of alcohol abuse. The effects of maternal alcohol consumption during pregnancy are most pronounced in poor, rural communities. Earlier research suggests that children with prenatal alcohol exposure have poor social behaviour; however, to date, no research has investigated their playfulness. This study investigated the differences in playfulness of children with and without prenatal alcohol exposure. Grade one learners with a positive history of prenatal alcohol exposure (n = 15) and a reference group without a positive history of prenatal alcohol exposure (n = 15) were filmed engaging in free play at their schools. The Test of Playfulness was used to measure playfulness from recordings. Data were subjected to Rasch analysis to calculate interval level measure scores for each participant. The overall measure scores and individual Test of Playfulness social items were subjected to paired samples t-tests to calculate if significant differences existed between the groups. Children with prenatal alcohol exposure had a significantly lower mean overall playfulness score than the reference group (t = -2.51; d.f. = 28; P = 0.02). Children with prenatal alcohol exposure also scored significantly lower than the reference group on 5 of the 12 Test of Playfulness items related to social play. This research suggests that children with prenatal alcohol exposure are more likely to experience poorer overall quality of play, with particular deficits in social play. Considering play is a child's primary occupation, this finding becomes pertinent for occupational therapy practice, particularly in post-apartheid South Africa, where high prenatal alcohol exposure prevalence rates are couched within persistent socio-economic inequalities. © 2014 Occupational Therapy Australia.

  11. Should prenatal hydronephrosis that resolves before birth be followed postnatally? Analysis and comparison to persistent prenatal hydronephrosis.

    Scarborough, Patrick L; Ferrara, Elizabeth; Storm, Douglas W

    2015-09-01

    Prenatal ultrasonography has greatly enhanced detection of congenital genitourinary abnormalities. However, although persistent prenatal hydronephrosis (PPH) is typically imaged and followed postnatally, it remains unclear if prenatal hydronephrosis that resolves in utero (RPH) should be similarly managed. We determined postnatal abnormalities associated with RPH and compared these to those associated with PPH. We performed a retrospective review of all consecutive patients evaluated for prenatal hydronephrosis over 24 months. Patients were followed prenatally with serial ultrasounds and postnatally with ultrasonography and a voiding cystourethrogram. Of the consecutive 165 patients enrolled in the study, 72 had RPH. The average prenatal anterior-posterior renal pelvis length was significantly longer in patients with PPH (5.5 mm) than in those with RPH (4.9 mm) (p = 0.01). Recurrent postnatal hydronephrosis occurred in 44% of patients with RPH, with eventual resolution in 34% of those affected. In comparison, 29% of PPH cases resolved postnatally. Mean time to resolution was statistically shorter for PPH (116 days) than for RPH (175 days) (p = 0.01). Seven PPH patients required surgery, while no RPH patients needed intervention (difference was statistically significant). A significant number of RPH children had postnatal hydronephrosis. Despite a slower resolution time, no children with RPH required intervention. Although RPH may recur postnatally, the significantly lower chance of intervention being required suggests that these children may not require postnatal imaging.

  12. Prenatal choline supplementation mitigates behavioral alterations associated with prenatal alcohol exposure in rats.

    Prenatal alcohol exposure can alter physical and behavioral development, leading to a range of fetal alcohol spectrum disorders. Despite warning labels, pregnant women continue to drink alcohol, creating a need to identify effective interventions to reduce the severity of alcohol's teratogenic effects. Choline is an essential nutrient that influences brain and behavioral development. Recent studies indicate that choline supplementation can reduce the teratogenic effects of developmental alcohol exposure. The present study examined whether choline supplementation during prenatal ethanol treatment could mitigate the adverse effects of ethanol on behavioral development. Pregnant Sprague-Dawley rats were intubated with 6 g/kg/day ethanol in a binge-like manner from gestational days 5-20; pair-fed and ad libitum chow controls were included. During treatment, subjects from each group were intubated with either 250 mg/kg/day choline chloride or vehicle. Spontaneous alternation, parallel bar motor coordination, Morris water maze, and spatial working memory were assessed in male and female offspring. Subjects prenatally exposed to alcohol exhibited delayed development of spontaneous alternation behavior and deficits on the working memory version of the Morris water maze during adulthood, effects that were mitigated with prenatal choline supplementation. Neither alcohol nor choline influenced performance on the motor coordination task. These data indicate that choline supplementation during prenatal alcohol exposure may reduce the severity of fetal alcohol effects, particularly on alterations in tasks that require behavioral flexibility. These findings have important implications for children of women who drink alcohol during pregnancy. © 2010 Wiley-Liss, Inc.

    Impact of ambient pollution upon children's asthma may differ by sex, and exposure dose and timing. Psychosocial stress can also modify pollutant effects. These associations have not been examined for in utero ambient nitrate exposure. We implemented Bayesian-distributed lag interaction models to identify sensitive prenatal windows for the influence of nitrate (NO 3 - ) on child asthma, accounting for effect modification by sex and stress. Analyses included 752 mother-child dyads. Daily ambient NO 3 - exposure during pregnancy was derived using a hybrid chemical transport (Geos-Chem)/land-use regression model and natural log transformed. Prenatal maternal stress was indexed by a negative life events score (high [>2] vs. low [≤2]). The outcome was clinician-diagnosed asthma by age 6 years. Most mothers were Hispanic (54%) or black (29%), had a high school education or less (66%), never smoked (80%), and reported low prenatal stress (58%); 15% of children developed asthma. BDILMs adjusted for maternal age, race, education, prepregnancy obesity, atopy, and smoking status identified two sensitive windows (7-19 and 33-40 wk gestation), during which increased NO 3 - was associated with greater odds of asthma, specifically among boys born to mothers reporting high prenatal stress. Cumulative effects of NO 3 - across pregnancy were also significant in this subgroup (odds ratio = 2.64, 95% confidence interval = 1.27-5.39; per interquartile range increase in ln NO 3 - ). Prenatal NO 3 - exposure during distinct sensitive windows was associated with incident asthma in boys concurrently exposed to high prenatal stress.

  15. In defense of prenatal genetic interventions.

    Science.gov (United States)

    Murphy, Timothy F

    2014-09-01

    Jürgen Habermas has argued against prenatal genetic interventions used to influence traits on the grounds that only biogenetic contingency in the conception of children preserves the conditions that make the presumption of moral equality possible. This argument fails for a number of reasons. The contingency that Habermas points to as the condition of moral equality is an artifact of evolutionary contingency and not inviolable in itself. Moreover, as a precedent for genetic interventions, parents and society already affect children's traits, which is to say there is moral precedent for influencing the traits of descendants. A veil-of-ignorance methodology can also be used to justify prenatal interventions through its method of advance consent and its preservation of the contingency of human identities in a moral sense. In any case, the selection of children's traits does not undermine the prospects of authoring a life since their future remains just as contingent morally as if no trait had been selected. Ironically, the prospect of preserving human beings as they are--to counteract genetic drift--might even require interventions to preserve the ability to author a life in a moral sense. In light of these analyses, Habermas' concerns about prenatal genetic interventions cannot succeed as objections to their practice as a matter of principle; the merits of these interventions must be evaluated individually. © 2012 John Wiley & Sons Ltd.

    1990-01-01

    Available data on the coverage of prenatal care in Latin America were reviewed. In recent years, only Bolivia had a coverage of prenatal care of less than 50 per cent. More than 90 per cent of pregnant women received prenatal care in Chile, Cuba, the Dominican Republic, and Puerto Rico. Prenatal care increased between the 1970 and 1980 in the Dominican Republic, Ecuador, Guatemala, Honduras, Mexico, and Peru. The coverage of prenatal care decreased in Bolivia and Colombia. The mean number of visits increased in Cuba and Puerto Rico. The increase of prenatal care in Guatemala and Honduras is due to increased care by traditional birth attendants, compared to the role of health care institutions. We compared the more recent data on tetanus immunization of pregnant women to the more recent data on prenatal care. The rates of tetanus immunization are always lower than the rates of prenatal care attendance, except in Costa Rica. The rates of tetanus immunization was less than half as compared to the rates of prenatal care in Bolivia, Guatemala, and Peru. To improve the content of prenatal care should be an objective complementary to the increase of the number of attending women.

    The advancing sophistication and availability of prenatal diagnostic technologies, such as transvaginal ultrasound, chorionic villus sampling, amniocentesis, and alpha feto-protein testing, have increased the medical capacity to detect genetic and congenital conditions during pregnancy. This paper raises many social and ethical questions about how families, craniofacial teams, and society respond when a prenatal diagnosis is made and considers the ethical and social issues around counseling, managing information, and making decisions. Ethical and sociological analysis. Implications examined on the societal, health professional, and family level. Families and health professionals often manage ambiguity, uncertainty, and complex decision making in facing a prenatal diagnosis. Embedded in parental and clinical decisions are values about children with birth defects. Families are making decisions about whether to bear or abort an affected fetus on the basis of their perceptions of the impairment and on their expectation of the burden involved for the family and the child. On a broader, societal level, pressures to conform and minimize human differences are apparent in biomedical interventions, the Human Genome Project, advertising and media images, and social pressures to normalize disabilities. How society deals with prenatal diagnosis will impact upon social values; moral, legal, and ethical perspectives; and on health policy. Prenatal diagnostic technologies raise complex ethical, family, policy, and legal issues that have broad implications for the lives of children born with special health care needs, including children with cleft lip and palate.

    Alcohol dependence is more prevalent in men than in women. The evidence for how prenatal and adult androgens influence alcohol dependence is limited. We investigated the effects of prenatal and adult androgen activity on alcohol dependence. Moreover, we studied how the behaviours of pregnant women affect their children's prenatal androgen load. We quantified prenatal androgen markers (e.g., second-to-fourth finger length ratio [2D : 4D]) and blood androgens in 200 early-abstinent alcohol-dependent in-patients and 240 controls (2013-2015, including a 12-month follow-up). We also surveyed 134 women during pregnancy (2005-2007) and measured the 2D : 4D of their children (2013-2016). The prenatal androgen loads were higher in the male alcohol-dependent patients compared to the controls (lower 2D : 4D, P = 0.004) and correlated positively with the patients' liver transaminase activities (P alcohol withdrawal severity (P = 0.019). Higher prenatal androgen loads and increasing androgen levels during withdrawal predicted earlier and more frequent 12-month hospital readmission in alcohol-dependent patients (P alcohol (P = 0.010) and tobacco consumption (P = 0.017), and lifetime stressors (P = 0.019) of women during pregnancy related positively to their children's prenatal androgen loads (lower 2D : 4D). Androgen activities in alcohol-dependent patients and behaviours of pregnant women represent novel preventive and therapeutic targets of alcohol dependence. © 2017 John Wiley & Sons A/S.

  3. Prenatal stress, prematurity and asthma

    Asthma is the most common chronic disease of childhood, affecting millions of children in the U.S. and worldwide. Prematurity is a risk factor for asthma, and certain ethnic or racial minorities such as Puerto Ricans and non-Hispanic Blacks are disproportionately affected by both prematurity and asthma. In this review, we examine current evidence to support maternal psychosocial stress as a putative link between prematurity and asthma, while also focusing on disruption of the hypothalamic-pituitary-adrenal (HPA) axis and immune responses as potential underlying mechanisms for stress-induced “premature asthma”. Prenatal stress may not only cause abnormalities in the HPA axis but also epigenetic changes in the fetal glucocorticoid receptor gene (NR3C1), leading to impaired glucocorticoid metabolism. Moreover, maternal stress can alter fetal cytokine balance, favoring Th2 (allergic) immune responses characteristic of atopic asthma: IL-6, which has been associated with premature labor, can promote Th2 responses by stimulating production of IL-4 and IL-13. Given a link among stress, prematurity, and asthma, future research should include birth cohorts aimed at confirming and better characterizing “premature asthma”. If confirmed, clinical trials of prenatal maternal stress reduction would be warranted to reduce the burden of these common co-morbidities. While awaiting the results of such studies, sound policies to prevent domestic and community violence (e.g. from firearms) are justified, not only by public safety but also by growing evidence of detrimental effects of violence-induced stress on psychiatric and somatic health.

    The prevalence of stuttering is much higher in males compared to females. The biological underpinnings of this skewed sex-ratio is poorly understood, but it has often been speculated that sex hormones could play an important role. The present study investigated a potential link between prenatal testosterone and stuttering. Here, an indirect indicator of prenatal testosterone levels, the Digit Ratio (2D:4D) of the hand, was used. As numerous studies have shown, hands with more "male" characteristics (putatively representing greater prenatal testosterone levels) are characterized by a longer ring finger compared to the index finger (represented as a lower 2D:4D ratio) in the general population. We searched for differences in the 2D:4D ratios between 38 persons who stutter and 36 persons who do not stutter. In a second step, we investigated potential links between the 2D:4D ratio and the multifaceted symptomatology of stuttering, as measured by the Overall Assessment of the Speaker's Experience of Stuttering (OASES), in a larger sample of 44 adults who stutter. In the first step, no significant differences in the 2D:4D were observed between individuals who stutter and individuals who do not stutter. In the second step, 2D:4D correlated negatively with higher scores of the OASES (representing higher negative experiences due to stuttering), and this effect was more pronounced for female persons who stutter. The findings indicate for the first time that prenatal testosterone may influence individual differences in psychosocial impact of this speech disorder. Copyright © 2014 Elsevier Ltd.

    Although banned in most countries, dichlorodiphenyl-trichloroethane (DDT) continues to be used for vector control in some malaria endemic areas. Previous findings from the Center for the Health Assessment of Mothers and Children of Salinas (CHAMACOS) cohort study found increased prenatal levels of DDT and its breakdown product dichlorodiphenyl-dichloroethylene (DDE) to be associated with altered neurodevelopment in children at 1 and 2years of age. In this study, we combined the measured maternal DDT/E concentrations during pregnancy obtained for the prospective birth cohort with predicted prenatal DDT and DDE levels estimated for a retrospective birth cohort. Using generalized estimating equation (GEE) and linear regression models, we evaluated the relationship of prenatal maternal DDT and DDE serum concentrations with children's cognition at ages 7 and 10.5years as assessed using the Full Scale Intelligence Quotient (IQ) and 4 subtest scores (Working Memory, Perceptual Reasoning, Verbal Comprehension, and Processing Speed) of the Wechsler Intelligence Scale for Children (WISC). In GEE analyses incorporating both age 7 and 10.5 scores (n=619), we found prenatal DDT and DDE levels were not associated with Full Scale IQ or any of the WISC subscales (p-value>0.05). In linear regression analyses assessing each time point separately, prenatal DDT levels were inversely associated with Processing Speed at age 7years (n=316), but prenatal DDT and DDE levels were not associated with Full Scale IQ or any of the WISC subscales at age 10.5years (n=595). We found evidence for effect modification by sex. In girls, but not boys, prenatal DDE levels were inversely associated with Full Scale IQ and Processing Speed at age 7years. We conclude that prenatal DDT levels may be associated with delayed Processing Speed in children at age 7years and the relationship between prenatal DDE levels and children's cognitive development may be modified by sex, with girls being more adversely

    Prenatal stress and prenatal nutrition each have demonstrable impact on fetal development, with implications for child neurodevelopment and behavior. However, few studies have examined their joint influences despite evidence of potential interactive effects. We examined associations among prenatal stress, prenatal antioxidant intakes, and child temperament in a sociodemographically diverse pregnancy cohort (N=137 mother-child dyads). In mid-pregnancy, mothers completed an assessment of recent negative life events as a measure of prenatal stress and an assessment of prenatal diet. When the children were 30 months of age, mothers completed the Early Childhood Behavior Questionnaire-Very Short form, which provides scores on child Negative Affectivity, Effortful Control, and Surgency/Extraversion. Linear regressions tested associations between maternal prenatal negative life events and child temperament, and effect modification by maternal prenatal antioxidant intakes (vitamins A, C, and E, magnesium, zinc, selenium, β-carotene). Analyses revealed that increased maternal prenatal negative life events were associated with higher child Negative Affectivity (β=0.08, P=0.009) but not with child Effortful Control (β=-0.03, P=0.39) or Surgency/Extraversion (β=0.04, P=0.14). Prenatal intakes of zinc and selenium modified this effect: Maternal exposure to prenatal negative life events was associated with higher child Negative Affectivity in the presence of lower intakes of zinc and selenium. Modification effects approached significance for vitamins A and C. The results suggest that the combination of elevated stress exposures and lower antioxidant intakes in pregnancy increases the likelihood of heightened child temperamental negative affectivity. Increased antioxidant intakes during pregnancy may protect against influences of prenatal stress on child temperament.

    Full Text Available The aim of the study was to investigate early executive functioning in young children from 6–35 months of age. The study involved 319 randomly selected children from the community, 17 HIV exposed but uninfected children and 31 HIV infected ARV-naive children. A variation of the A-not-B task was used. While there were no group differences in total correct, perseverative errors, nor maximum error run, a significant percentage of children were unable to complete the task as a consequence of the children becoming overtly distressed or refusing to continue. In a multivariate analysis we observed that the significant predictors of non-completion were HIV exposure (both infected and exposed and being under 24 months of age. These patterns of results indicate that future work with a broader array of tasks need to look at the association of HIV and EF tasks and potential contribution of factors such as emotion regulation, persistence and motivation on performance on EF tasks.

  16. Biological effects of prenatal irradiation

    International Nuclear Information System (INIS)

    Streffer, Christian

    1997-01-01

    After large releases of radionuclides, exposure of the embryo or fetus can take place by external irradiation or uptake of radionuclies. The embryo and fetus are radiosensitive throughout prenatal development. The quality and extent of radiation effects depend on the development stage. During the preimplantation period (one to 10 days postconception, p.c.) a radiation exposure of at least 0.2 Gy can cause the death of the embryo. Malformations are only observed in rare cases when genetic predisposition exist. Macroscopic, anatomical malformations are induced only after irradiation during the major organogenesis (two to eight weeks p.c.). A radiation dose of about 0.2 Gy is a doubling dose for the malformation risks as extrapolated from experiments with rodents. The human embryo may be more radioresistant. During early fetogenesis (8-15 weeks p.c.) a high radiosensitivity exists for the developmental of the brain. Radiation doses of 1.0 Gy cause severe mental retardation in about 40% of the exposed fetuses. It must be taken into account that a radiation exposure during the fetal period can also induce cancer. It is generally assumed that the risk exists at about the same level as for children. (Author)

    Rationale: Exploring prenatal factors influencing childhood wheeze may inform programming mechanisms. Objectives: We examined associations among prenatal maternal cortisol profiles, maternal obesity, and repeated wheeze up to age 2 years (n = 261). Methods: Salivary cortisol was collected five times per day over 3 days at 29.0 ± 4.9 weeks gestation. Mothers were categorized as obese (body mass index ≥ 30 kg/m2) versus nonobese (body mass index cortisol metrics (level at each time point, morning rise, diurnal and afternoon slopes) and obesity on wheeze adjusting for covariates. Linear mixed models were implemented to examine associations between cortisol trajectories and wheezing. Interactions between maternal cortisol and obesity were considered. Measurements and Main Results: Mothers were primarily minority (56.5% Hispanic, 24.1% African American), 61% had less than or equal to 12 years of education, 34% were obese, and 8.4% of children had repeated wheeze. An interquartile range increase in mean log cortisol at bedtime (odds ratio, 2.2; 95% confidence interval, 1.09–4.09) and maternal obesity (odds ratio, 3.43; 95% confidence interval, 1.26–9.35) were independently associated with wheeze. Linear mixed models revealed an association between a flatter afternoon slope (slower decline in log cortisol per hour) and repeated wheeze in children of obese mothers (children with [−0.017 change] and without [−0.061 change] wheeze [P = 0.009 for time × wheeze interaction]), but not in children of nonobese mothers (with [−0.050 change] and without [−0.061 change] wheeze [P = 0.51]). Conclusions: Maternal prenatal cortisol disruption and obesity were independently associated with children’s wheeze. Obese women with adverse cortisol profiles were most likely to have children with repeated wheeze. PMID:23590260

    Evidence shows that diet contributes substantially to lifelong physical and mental health. Although dietary exposure during gestation and early postnatal life is critical, human epidemiological data are limited regarding its link with children's subsequent externalizing issues. The aim of this study was to investigate the role of maternal diet during pregnancy in offspring's symptoms of hyperactivity-inattention and conduct problems from ages 3 to 8 years. We used data of 1,242 mother-child pairs from a French cohort followed up from pregnancy until the children were 8 years of age. Dietary patterns (DP) of the mother during pregnancy were assessed with food frequency questionnaires. Children's externalizing behavior was assessed with the Strength and Difficulties Questionnaire at ages 3, 5, and 8 years, from which trajectories of hyperactivity-inattention symptoms and conduct problems were derived. We conducted multivariable logistic models to study associations adjusted for a range of potential confounders. Results showed significant relationships between maternal 'low Healthy diet' (adjusted Odds Ratio (aOR) = 1.61; IC 95%: 1.09-2.37) and 'high Western diet' (aOR = 1.67; IC 95%: 1.13-2.47) during pregnancy and children's trajectories of high symptoms of hyperactivity-inattention. The associations took into account relevant confounders such as DP of the children at age 2 years, maternal stress and depression, gestational diabetes, and socioeconomic variables. Maternal diet during pregnancy was independently associated with children's hyperactivity-inattention symptoms but not with conduct problems. Early prevention addressing lifestyle should specifically target diet in pregnant women. © 2018 Association for Child and Adolescent Mental Health.

    A large body of literature documents the effects of prenatal exposure to polychlorinated biphenyls (PCBs) on cognitive development of children. Despite this fact, no integrative synthesis has been published yet to identify the cognitive functions that are particularly affected. Our aim is to review this literature in an attempt to identify the cognitive profile associated with prenatal PCB exposure. Studies were identified by searching the PubMed database for articles published before June 2008. We reviewed data from nine prospective longitudinal birth cohorts for different aspects of cognition. Associations between indicators of prenatal PCB exposure and performance on cognitive tasks reported in the selected studies are summarized and classified as general cognitive abilities, verbal or visual-spatial skills, memory, attention, and executive functions. The most consistent effects observed across studies are impaired executive functioning related to increased prenatal PCB exposure. Negative effects on processing speed, verbal abilities, and visual recognition memory are also reported by most studies. Converging results from different cohort studies in which exposure arises from different sources make it unlikely that co-exposure with another associated contaminant is responsible for the observed effects. Prenatal PCB exposure appears to be related to a relatively specific cognitive profile of impairments. Failure to assess functions that are specifically impaired may explain the absence of effects found in some studies. Our findings have implications in the selection of cognitive assessment methods in future studies.

    Prenatal exposure to alcohol is associated with cognitive, behavioral and social deficits, including delinquency. Although delinquent populations and those with intellectual and behavioral deficits exhibit impaired moral judgment and reasoning, this area remains unexplored in alcohol-exposed individuals. Moral maturity and delinquency were evaluated in 27 participants with prenatal alcohol exposure (ALC group) and 29 nonexposed controls (CON group) matched on age (range: 10-18), gender, handedness, socioeconomic status and ethnicity. Moral maturity was evaluated using the Sociomoral Reflection Measure-Short Form, and delinquency was evaluated with the Conduct Disorder (CD) Questionnaire. Additional measures included social desirability and inhibition. The ALC group performed at a lower level of moral maturity than the CON group. Whereas Verbal IQ primarily predicted this difference, a deficit on the moral value judgment having to do with relationships with others was specific to prenatal alcohol exposure. Furthermore, delinquency was higher in the ALC group, and specific sociomoral values were predictive of delinquent behavior. Finally, half of the children and adolescents with a history of prenatal alcohol exposure but without fetal alcohol syndrome had probable CD. The results of this study indicate that interventions aimed at reducing delinquency in those with prenatal alcohol exposure are necessary, and targeting moral judgment for this purpose may be beneficial.

    Locus of control is one of the most widely studied concepts in the history of personality psychology. In spite of its popularity and its associations with numerous relevant outcomes, the ability of locus of control to predict future behaviors involving parenting effectiveness has been under researched. The few parent locus of control children's outcome studies are characterized by cross-sectional methodologies that focus on mothers. The present study uses a prospective methodology to compare data on mothers' and fathers' locus of control with their child's behavior outcomes from a large scale research project, the Avon Longitudinal Study of Parents and Children (ALSPAC). Based on Rotter's Social Learning Theory published in 1954 and past empirical research, it was predicted and found that parent internality was associated with more positive child outcomes than parent externality. More specifically, when both parents were internal, their children had more positive outcomes in sleeping, eating, and tantrum behavior as compared to any other parent locus of control combination. However external parents had a less restrictive attitude which appeared to have a more beneficial effect on picky eating. Results confirmed how important parent locus of control is in the lives of children. Based on the findings, researchers are urged to develop interventions to change advice to parents and promote more internal locus of control among parents.

  8. Parental Virtue and Prenatal Genetic Alteration Research.

    2015-12-01

    Although the philosophical literature on the ethics of human prenatal genetic alteration (PGA) purports to inform us about how to act, it rarely explicitly recognizes the perspective of those who will be making the PGA decision in practice. Here I approach the ethics of PGA from a distinctly virtue-based perspective, taking seriously what it means to be a good parent making this decision for one's child. From this perspective, I generate a sound verdict on the moral standing of human PGA (research): given the current state of the art, good parents have compelling reason not to consent to PGA (research) for their child, especially as part of the first wave(s) of PGA research participants and especially for non-medically oriented purposes. This is because doing otherwise is inconsistent with a plausible and defensible understanding of virtuous parenting and parental virtues, founded on a genuine concern for promoting the overall flourishing of the eventual child. In essence, given the current and foreseeable state of the art, parents who allow prenatal genetic alteration of their children are less-than-virtuous parents to those children, even in cases where they have a right to do so and even if PGA turns out to be beneficial to the eventual child.

Cutaneous examination revealed moist eroded areas in the perianal region and fine scaly lesions over palms and soles. Radiograph of both upper limbs and limbs revealed early periosteal changes in lower end of humerus and lower end of tibia. Diagnosis of early pre-natal syphilis was confirmed by Child′s Serum Rapid Plasma Reagin Antibody test [S.RPR] being positive with 1:64 dilution while that of mother was 1:8.

    Congenital hydronephrosis is one of the most common anomalies identified on antenatal ultrasound. The underlying etiology of congenital hydronephrosis is multifold, ranging from transient hydronephrosis in utero to clinically significant congenital anomalies of the kidney and urinary tract. While traditional management of hydronephrosis was aimed at relieving symptoms, the advent of routine prenatal ultrasound has led to a shift in the goal of treatment to prevention of renal injury in the asymptomatic patient. However, despite this focus on renal preservation, the diagnostic criteria for identification of children "at risk" for renal damage that can be alleviated by surgical treatment remain a subject of debate. Both antenatal and postnatal imaging studies have been evaluated as indicators for potential reversible renal damage and have been used as potential indicators of the need for surgical intervention. The aim of this review is to discuss the current literature regarding the role of postnatal clinical and radiographic evaluation to identify children who may benefit from early surgical intervention.

    To evaluate the effects of maternal lead exposure during pregnancy on toddler cognitive development and the potential effect modification by maternal stress. We conducted a prospective birth-cohort study in Shanghai from 2010 to 2012 and investigated 225 mother-infant pairs. The mothers were recruited in mid-to-late pregnancy and children were followed up until 24-36 months old. A self-administered Symptom Checklist-90-Revised Scale (SCL-90-R) was used to assess maternal emotional stress during pregnancy. Maternal whole blood lead levels were measured during gestational weeks 28-36. The toddlers' cognitive levels were assessed using the Gesell Development Scale. Multiple linear regression models were established to explore the main effects of prenatal lead exposure on toddlers' cognitive abilities and the modifying effects of maternal stress. Covariate information was collected through interviews, questionnaires and medical records. The mean maternal blood lead concentration was 3.30 (95%CI: 3.05, 3.57) μg/dL. After adjusting for relevant confounders, no significant associations of maternal blood lead concentrations with toddlers' cognitive levels were observed in all five domains of the Gesell scale (P>0.05). However, the interaction between prenatal maternal blood lead and stress was significant in the domains of adaptive behavior, language and social behavior. When stratified by maternal stress levels, compared with non-significant associations (P>0.05) among low (P1-P75) prenatal stress group, adverse associations between maternal blood lead concentrations (log10-transformed) and toddlers' cognitive levels were observed among high (P75-P100) prenatal stress group in the domains of language (β=-33.82, 95%CI: -60.04, -7.59), social behavior (β=-41.00, 95%CI: -63.11, -18.89) and adaptive behavior (β=-17.93, 95%CI: -35.83, -0.03). Prenatal maternal stress may exacerbate the deleterious effects of prenatal exposure to lead on toddler cognitive development

    2007-04-01

    Research reveals that prenatal alcohol exposure and child trauma (i.e., abuse, neglect, sexual abuse) can have deleterious effects on child development across multiple domains. This study analyzed the impact on childhood neurodevelopment of prenatal alcohol exposure and postnatal traumatic experience compared to postnatal traumatic experience alone. Although the harmful effects of both have been well documented individually, there is no research documenting the concurrent effects of prenatal alcohol exposure and postnatal trauma on a child's developmental process. Transdisciplinary assessment of the children included the core disciplines of medicine, speech-language pathology, occupational therapy, social work, and psychology. Medical examination, standardized developmental and intelligence testing, projective tools, parent questionnaires, and psychosocial interviews provided information in the primary developmental areas. Findings indicated that children who had been exposed prenatally to alcohol along with postnatal traumatic experience had lower intelligence scores and more severe neurodevelopmental deficits in language, memory, visual processing, motor skills, and attention than did traumatized children without prenatal alcohol exposure, as well as greater oppositional/defiant behavior, inattention, hyperactivity, impulsivity, and social problems. Successful teacher and speech-language pathologist interventions with traumatized children with prenatal alcohol exposure demand a paradigm shift that requires the development of new perspectives and ongoing training.

    Full Text Available Abstract Background Alcohol related neurodevelopmental disorder (ARND falls under the umbrella of fetal alcohol spectrum disorder (FASD, but individuals do not demonstrate the facial characteristics associated with fetal alcohol syndrome (FAS, making diagnosis difficult. While attentional problems in ARND are similar to those found in attention-deficit/hyperactivity disorder (ADHD, the underlying impairment in attention pathways may be different. Methods Functional magnetic resonance imaging (fMRI of a working memory (1-back task of 63 children, 10 to 14 years old, diagnosed with ARND and ADHD, as well as typically developing (TD controls, was conducted at 3 T. Diffusion tensor imaging (DTI data were also acquired. Results Activations were observed in posterior parietal and occipital regions in the TD group and in dorsolateral prefrontal and posterior parietal regions in the ARND group, whereas the ADHD group activated only dorsolateral prefrontal regions, during the working memory component of the task (1-back minus 0-back contrast. The increases in frontal and parietal activity were significantly greater in the ARND group compared to the other groups. This increased activity was associated with reduced accuracy and increased response time variability, suggesting that ARND subjects exert greater effort to manage short-term memory load. Significantly greater intra-subject variability, demonstrated by fMRI region-of-interest analysis, in the ADHD and ARND groups compared to the TD group suggests that moment-to-moment lapses in attention contributed to their poorer task performance. Differences in functional activity in ARND subjects with and without a diagnosis of ADHD resulted primarily from reduced activation by the ARND/ADHD + group during the 0-back task. In contrast, children with ADHD alone clearly showed reduced activations during the 1-back task. DTI analysis revealed that the TD group had significantly higher total tract volume

  15. Prenatal anxiety effects: A review.

    Field, Tiffany

    2017-11-01

    This review is based on literature on prenatal anxiety effects that was found on Pubmed and PsycINFO for the years 2010-2016. Prenatal anxiety is thought to have distinct features, although it has been measured both by specific prenatal anxiety symptoms as well as by standardized anxiety scales. Its prevalence has ranged from 21 to 25% and it has been predicted by a number of pregnancy - related variables such as unintended pregnancy, demographic variables such as low acculturation and income and psychosocial factors including pessimism and partner tension. Prenatal anxiety effects on pregnancy include increased cortisol levels, pro-inflammatory cytokines, obstetric problems and cesarean section. Effects on the neonate include lower gestational age, prematurity, less insulin-like growth factor in cord blood, less exclusive breast-feeding and less self-regulation during the heelstick procedure. Prenatal anxiety effects continue into infancy and childhood both on physiological development and emotional/mental development. Among the physiological effects are lower vagal activity across the first two years, and lower immunity, more illnesses and reduced gray matter in childhood. Prenatal anxiety effects on emotional/mental development include greater negative emotionality and in infants, lower mental development scores and internalizing problems. Anxiety disorders occur during childhood and elevated cortisol and internalizing behaviors occur during adolescence. Interventions for prenatal anxiety are virtually nonexistent, although stroking (massaging) the infant has moderated the pregnancy - specific anxiety effects on internalizing behaviors in the offspring. The limitations of this literature include the homogeneity of samples, the frequent use of anxiety measures that are not specific to pregnancy, and the reliance on self-report. Nonetheless, the literature highlights the negative, long-term effects of prenatal anxiety and the need for screening and early

    The study aim was to investigate the association between prenatal exposure to endocrine disrupting chemicals (EDCs) and the body composition of 7 to 9 year old Flemish children. The subjects were 114 Flemish children (50% boys) that took part in the first Flemish Environment and Health Study (2002–2006). Cadmium, PCBs, dioxins, p,p′-DDE and HCB were analysed in cord blood/plasma. When the child reached 7–9 years, height, weight, waist circumference and skinfolds were measured. Significant associations between prenatal exposure to EDCs and indicators of body composition were only found in girls. After adjustment for confounders and covariates, a significant negative association was found in girls between prenatal cadmium exposure and weight, BMI and waist circumference (indicator of abdominal fat) and the sum of four skinfolds (indicator of subcutaneous fat). In contrast, a significant positive association (after adjustment for confounders/covariates) was found between prenatal p,p′-DDE exposure and waist circumference as well as waist/height ratio in girls (indicators of abdominal fat). No significant associations were found for prenatal PCBs, dioxins and HCB exposure after adjustment for confounders/covariates. This study suggests a positive association between prenatal p,p′-DDE exposure and indicators of abdominal fat and a negative association between prenatal cadmium exposure and indicators of both abdominal as well as subcutaneous fat in girls between 7 and 9 years old. - Highlights: • Associations between prenatal contaminant exposure and anthropometrics in children. • Significant association only found in girls. • No significant associations found for prenatal PCBs, dioxins and HCB exposure. • Girls: negative association between cadmium and abdominal and subcutaneous fat. • Girls: positive association between p,p′-DDE and indicators of abdominal fat

  18. Comparing CenteringPregnancy® to standard prenatal care plus prenatal education

    Science.gov (United States)

    2013-01-01

    Background There is significant evidence to support the importance of prenatal care in preventing adverse outcomes such as preterm birth and low infant birth weight. Previous studies have indicated that the benefits of prenatal care are not evenly distributed throughout the social strata. In addition, emerging evidence suggests that among particular populations, rates of preterm birth are unchanged or increasing. This suggests that an alternate care model is necessary, one that seeks to addresses some of the myriad of social factors that also contribute to adverse birth outcomes. In previous studies, the group prenatal care model CenteringPregnancy® had been shown to reduce adverse birth outcomes, but to date, no comparison had been made with a model that included prenatal education. This study sought to investigate whether any significant difference remained within the comparison groups when both models accounted for social factors. Methods This analysis was based on survey data collected from a prospective cohort of pregnant women through the All Our Babies Study in Calgary, Alberta. Results At baseline, there were significant differences between the comparison groups in their psychosocial health, with the women in the CenteringPregnancy® group scoring higher levels of depressive symptoms, stress and anxiety. At four months postpartum, the differences between the groups were no longer significant. Conclusions: These results suggest that CenteringPregnancy® can recruit and retain a demographically vulnerable group of women with a constellation of risk factors for poor pregnancy and birth outcomes, including poverty, language barriers and poor mental health. Post program, the rates of stress, anxiety and depression were similar to other women with more social and financial advantage. These findings suggest that CenteringPregnancy® may be a community based care strategy that contributes to improved mental health, knowledge, and behaviours to optimize outcomes

    To identify prenatal, perinatal and postnatal risk factors in children with autism spectrum disorder (ASD) by comparing them to their siblings without autistic disorders. The present study is cross sectional and comparative. It was conducted over a period of three months (July-September 2014). It included 101 children: 50 ASD's children diagnosed according to DSM-5 criteria and 51 unaffected siblings. The severity of ASD was assessed by the CARS. Our study revealed a higher prevalence of prenatal, perinatal and postnatal factors in children with ASD in comparison with unaffected siblings. It showed also a significant association between perinatal and postnatal factors and ASD (respectively p=0.03 and p=0.042). In this group, perinatal factors were mainly as type of suffering acute fetal (26% of cases), long duration of delivery and prematurity (18% of cases for each factor), while postnatal factors were represented principally by respiratory infections (24%). As for parental factors, no correlation was found between advanced age of parents at the moment of the conception and ASD. Likewise, no correlation was observed between the severity of ASD and different factors. After logistic regression, the risk factors retained for autism in the final model were: male gender, prenatal urinary tract infection, acute fetal distress, difficult labor and respiratory infection. The present survey confirms the high prevalence of prenatal, perinatal and postnatal factors in children with ASD and suggests the intervention of some of these factors (acute fetal distress and difficult labor, among others), as determinant variables for the genesis of ASD.

    The impact of prenatal ambient air pollution on child asthma may be modified by maternal stress, child sex, and exposure dose and timing. We prospectively examined associations between coexposure to prenatal particulate matter with an aerodynamic diameter of less than 2.5 microns (PM 2.5 ) and maternal stress and childhood asthma (n = 736). Daily PM 2.5 exposure during pregnancy was estimated using a validated satellite-based spatiotemporally resolved prediction model. Prenatal maternal negative life events (NLEs) were dichotomized around the median (high: NLE ≥ 3; low: NLE stress and child sex. Bayesian distributed lag interaction models identified a critical window of exposure (19-23 weeks' gestation, cumulative odds ratio, 1.15; 95% CI, 1.03-1.26; per interquartile range [1.7 μg/m 3 ] increase in prenatal PM 2.5 level) during which children concomitantly exposed to prenatal PM 2.5 and maternal stress had increased risk of asthma. No significant association was seen in children born to women reporting low prenatal stress. When examining modifying effects of prenatal stress and fetal sex, we found that boys born to mothers with higher prenatal stress were most vulnerable (19-21 weeks' gestation; cumulative odds ratio, 1.28; 95% CI, 1.15-1.41; per interquartile range increase in PM 2.5 ). Prenatal PM 2.5 exposure during sensitive windows is associated with increased risk of child asthma, especially in boys concurrently exposed to elevated maternal stress.

    M. Genco Usta

    2012-03-01

    Full Text Available The influence of prenatal stress on psychopathology has been observed in many animal and human studies. In many studies, stress during prenatal period has been shown to result in negative feedback dysregulation and hyperactivity of hypothalamo-pituitary-adrenocortical axis. Prenatal stres also may cause increased risk of birth complications, startle or distress in response to novel and surprising stimuli during infancy; lower Full Scale IQs, language abilities and attention deficiency in period of 3-5 years; increased risk of attention deficit hyperactivity syndrome, anxiety symptoms, depressive disorder and impulsivity during adolescence. Additionally, timing of prenatal stress is also important and 12-22 weeks of gestation seems to be the most vulnerable period. The results underline the need for early prevention and intervention programs for highly anxious women during pregnancy. Administration of prenatal stress monitoring to public health programs or removing pregnant women who have been exposed to life events such as natural disaster, terror attack to secure areas that provide basic needs may be crucial.

    In a longitudinal birth cohort study of inner-city mothers and children (Columbia Center for Children's Environmental Health), we have previously reported that prenatal exposure to chlorpyrifos (CPF) was associated with neurodevelopmental problems at 3 years of age. The goal of the study was to estimate the relationship between prenatal CPF exposure and neurodevelopment among cohort children at 7 years of age. In a sample of 265 children, participants in a prospective study of air pollution, we measured prenatal CPF exposure using umbilical cord blood plasma (picograms/gram plasma) and 7-year neurodevelopment using the Wechsler Intelligence Scale for Children, 4th edition (WISC-IV). Linear regression models were used to estimate associations, with covariate selection based on two alternate approaches. On average, for each standard deviation increase in CPF exposure (4.61 pg/g), Full-Scale intelligence quotient (IQ) declined by 1.4% and Working Memory declined by 2.8%. Final covariates included maternal educational level, maternal IQ, and quality of the home environment. We found no significant interactions between CPF and any covariates, including the other chemical exposures measured during the prenatal period (environmental tobacco smoke and polycyclic aromatic hydrocarbons). We report evidence of deficits in Working Memory Index and Full-Scale IQ as a function of prenatal CPF exposure at 7 years of age. These findings are important in light of continued widespread use of CPF in agricultural settings and possible longer-term educational implications of early cognitive deficits.

    Childhood pneumonia is one of the leading single causes of mortality and morbidity in children worldwide, but its etiology still remains unclear. We investigate the association between childhood pneumonia and exposure to diurnal temperature variation (DTV) in different timing windows. We conducted a prospective cohort study of 2,598 children aged 3-6 years in Changsha, China. The lifetime prevalence of pneumonia was assessed by a questionnaire administered by the parents. Individual exposure to DTV during both prenatal and postnatal periods was estimated. Logic regression models was used to examine the association between childhood pneumonia and DTV exposure in terms of odds ratios (OR) and 95% confidence interval (CI). Lifetime prevalence of childhood pneumonia in preschool children in Changsha was high up to 38.6%. We found that childhood pneumonia was significantly associated with prenatal DTV exposure, with adjusted OR (95%CI) =1.19 (1.02-1.38), particularly during the second trimester. However, childhood pneumonia not associated with postnatal DTV exposure. Sensitivity analysis indicated that boys are more susceptible to the pneumonia risk of diurnal temperature variation than girls. We further observed that the prevalence of childhood pneumonia was decreased in recent years as DTV shrinked. Early childhood pneumonia was associated with prenatal exposure to the diurnal temperature variation (DTV) during pregnancy, particularly in the second trimester, which suggests fetal origin of childhood pneumonia.

    Full Text Available With the objective of evaluating the quality of prenatal and analyse the epidemiological data of their women in the city of Tefé, in the interior of the Amazon, was a study descriptive and quantitative, secondary source documentation, by evaluation of the book of records that contain information about the card of their women who attended prenatal 93 in Tefé Regional Hospital of that city in April 2009. The results showed that the average age of women in labour was 23.3 years, most completed elementary education, and more than 50% have stable relationship, being three the number of children. Regarding prenatal assessment, 55% prenatal began until the fourth month, approximately 46% held six consultations during the prenatal,22.6% had 65.6% have 6 queries, at least 1 time basic examinations and 77% were immunized. The comparison of these results with other studies conducted in different regions of Brazil served as a tool to compare prenatal assessment in several Brazilian States. Is of great value the result of this research for improvement of care, since there are no records of assessment of quality of care provided during prenatal Amazonas State and also to encourage new research in the State.

    Maternal and child mortality are the key indicators of health and development of the country. Maternal and child health are interconnected to prenatal care. Consulting a doctor at the prenatal stage will not only ensure mother's and her unborn babies' safety, but also has a great influence to reduce the maternal and infant mortality. In this paper, an attempt has been made to analyze the status of prenatal care provided by the qualified doctor among pregnant mothers in Bangladesh. Data and required information of 8793 reproductive women were collected from the Bangladesh Demographic and Health Survey (BDHS) 2014. Logistic regression model has been used to identify the most significant determinants of the prenatal doctor visits. In this research, it is found that prenatal cares by a qualified doctor during pregnancy depend on several social and demographic characteristics of a woman. It is observed that women staying both urban and rural areas have similar behaviour of caring regarding their pregnancy related complications. Beside this Respondent's age, education, her husband's education and the number of ever born children have significant contribution on prenatal doctor visit. On the other hand, division, religion, husband's desire for children has no effect on it. Overall the model is able to predict 71.65% women into their appropriate group based on these factors.

    Meditation is important in facilitating health. Pregnancy health has been shown to have significant consequences for infant behaviors. In view of limited studies on meditation and infant temperament, this study aims to explore the effects of prenatal meditation on these aspects. The conceptual framework was based on the postulation of positive relationships between prenatal meditation and infant health. A randomized control quantitative study was carried out at Obstetric Unit, Queen Elizabeth Hospital in Hong Kong. 64 pregnant Chinese women were recruited for intervention and 59 were for control. Outcome measures were cord blood cortisol, infant salivary cortisol, and Carey Infant Temperament Questionnaire. Cord blood cortisol level of babies was higher in the intervention group (pmeditation can influence fetal health. Carey Infant Temperament Questionnaire showed that the infants of intervention group have better temperament (pmeditation in relation to child health. Present study concludes the positive effects of prenatal meditation on infant behaviors and recommends that pregnancy care providers should provide prenatal meditation to pregnant women.

    Examine factors influencing late (> sixth month of gestation) entry into prenatal care by race/ethnicity and insurance payer. The study population was drawn from singleton live births in California from 2007-2012 in the birth cohort file maintained by the California Office of Statewide Health Planning and Development, which includes linked birth certificate and mother and infant hospital discharge records. The sample was restricted to infants delivered between 20 and 44 weeks gestation. Logistic regression was used to calculate relative risks (RR) and 95% confidence intervals (CI) for factors influencing late entry into prenatal care. Maternal age, education, smoking, drug or alcohol abuse/dependence, mental illness, participation in the Women, Infants and Children's program and rural residence were evaluated for women entering prenatal care > sixth month of gestation compared with women entering prenatal care entry for each race or ethnicity and insurance payer. The sample included 2 963 888 women. The percent of women with late entry into prenatal care was consistently higher among women with public versus private insurance. Less than 1% of white non-Hispanic and Asian women with private insurance entered prenatal care late versus more than 4% of white non-Hispanic and black women with public insurance. After stratifying by race or ethnicity and insurance status, women less than 18 years of age were more likely to enter prenatal care late, with young Asian women with private insurance at the highest risk (15.6%; adjusted RR 7.4, 95% CI 5.3-10.5). Among all women with private insurance, > 12-year education or age > 34 years at term reduced the likelihood of late prenatal care entry (adjusted RRs 0.5-0.7). Drugs and alcohol abuse/dependence and residing in a rural county were associated with increased risk of late prenatal care across all subgroups (adjusted RRs 1.3-3.8). Participation in the Women, Infants and Children's program was associated with decreased

    α-Thalassemia is a common inherited disease in southern China. The severest form is Hb Bart's hydrops fetalis, in which the affected fetuses almost always die in utero or shortly after birth, and the mothers are at high risk for severe morbidity. Therefore, this condition should be controlled, especially prenatally. In this study, we reported on a two-year experience in prenatal control of Hb Bart's hydrops fetalis at a mainland Chinese hospital. Totally, 573 pregnancies at risk for Hb Bart's hydrops fetalis were referred and different prenatal procedures were offered depending on the gestational age at presentation. One hundred fifty-two affected fetuses were diagnosed prenatally; among these, only half presented in early gestation, and were terminated in time. Although our prenatal program has successfully prevented the birth of children with severe thalassemia, it does not show a satisfactory outcome, considering the gestational age when an affected pregnancy is terminated.

    2017-12-01

    In the present review, we examine the association between maternal prenatal stress or anxiety and children's early negative reactivity or self-regulation. The review includes 32 studies that focus on pregnancy-related anxiety, state or trait anxiety, perceived stress, and stressful life events in relation to child's crying, temperament, or behavior during the first 2 years of life. We searched four electronic databases and 32 studies were selected based on the inclusion criteria. Twenty-three studies found an association between maternal prenatal anxiety or stress and a child's negative reactivity or self-regulation, and typically the effect sizes varied from low to moderate. The association was found regardless of the form of prenatal stress or anxiety and the trimester in which the prenatal stress or anxiety was measured. In conclusion, several forms of prenatal anxiety and stress may increase the risk of emotional and self-regulatory difficulties during the first 2 years of life.

    We report the clinical characteristics and the outcome of two cases of pontocerebellar hypoplasia (PCH) in one family. The objective of this report is to describe the mode of presentation, discuss the clinical course, and address the dilemma of prenatal diagnosis and the prospects for genetic diagnosis for PCH. The first case is a 4-year-old boy in whom the diagnosis was made in the neonatal period. Despite extensive prenatal follow-up during the mother's subsequent pregnancy, prenatal diagnosis could not be made and a second affected child was born. Both siblings have severe developmental delay. The cases raise an important ethical dilemma about the most appropriate intervention if the mother of a child affected with PCH becomes pregnant. PCH is considered to have an autosomal-recessive mode of inheritance and a recurrence risk of 25% in each pregnancy. Until recently when genetic mutations in PCH types 2, 4, and 6 began to be identified, the lack of well-recognized genetic testing precluded experts from making clear recommendations. The best advice to these parents was difficult or elusive. With two children currently affected, should the parents terminate or continue with the latest pregnancy? Extensive monitoring with serial prenatal ultrasound failed in the previous pregnancy and resulted in the birth of the second affected child. It is evident that serial ultrasound scan may not be helpful in making the diagnosis prenatally. Therefore, other diagnostic modalities such as magnetic resonance imaging may be necessary and should be considered. With the identification of genetic basis or mutations in PCH types 2, 4, and 6 and possible development of commercial genetic testing for these types of PCH, reproductive decision or genetic testing during pregnancy should be recommended to affected families to enable informed choices.

    For many diseases, the comparison of prenatal diagnosis with a histopathological reality is not always possible. Fetal lung pathology, with its high rate of surgery in postnatal, allows this assessment. This study proposes an approach to the reliability of prenatal diagnosis and analysis of the postnatal development of all children in care for congenital pulmonary malformation (CPM). This is a retrospective study of all cases of CPM diagnosed in Poitiers University Hospital from 1995 to 2011. Cases diagnosed prenatally were identified and the diagnostic accuracy was studied by histology when cases had surgery. The postnatal development of prenatally diagnosed cases is described and compared to children who did not receive prenatal diagnosis. Among the 45 cases of CPM supported at the Poitiers University Hospital, 30 had received prenatal diagnosis of isolated CPM. The diagnostic concordance between antenatal ultrasound and the final diagnosis is κ=0.67 (CI95% [0.38 to 0.94]). The sensitivity of ultrasound was 90% (CI95% [55-99.7]) in our series for the diagnosis of CAMP (cystic adenomatoid malformation pulmonary). We found a sonographic disappearance of lesions in 4 children, 1 child in regression, stable lesions in 21 cases. Four children showed an increase in volume of the malformation, with signs of poor tolerance in 3 cases. After birth, children who received a prenatal diagnosis were no more symptomatic than those whose diagnosis was made postnatal: 21 (70%) versus 11 (73%; P=1) respectively. Similarly, they often received prophylactic surgery: 18 (60%) versus 2 (13%) respectively (P<0.01) and less often suffered post-surgery complication: 3 (10%) versus 10 (67%) respectively (P<0.01). The number of children monitored was not significantly different in the two groups. Prenatal diagnosis allows for the precise nature of the lesion in 90% of cases in 2013 and had no impact on symptomatology at birth. When prenatal diagnosis is possible, preventive

    Prenatal detection of chromosome abnormalities has been offered for more than 40 years, first by amniocentesis in the early 1970s and additionally by chorionic villus sampling (CVS) in the early 1980s. Given the well-recognized association between increasing maternal age and trisomy,1-3 the primary utilization of prenatal testing has been by older mothers. This has drastically reduced the incidence of aneuploid children born to older mothers.4 Although younger women have relatively low risks of conceiving a child with aneuploidy, the majority of pregnant women are in their late teens, 20s, and early 30s. As such, most viable aneuploid babies are born to these younger mothers.5 Invasive prenatal diagnosis (CVS and amniocentesis) is not a feasible option for all low-risk mothers, as these procedures carry a small but finite risk and would ultimately cause more miscarriages than they would detect aneuploidy. For this reason, a number of noninvasive tests have been developed-including first-trimester risk assessment at 11 to 14 weeks, maternal serum analyte (quad) screening at 15 to 20 weeks, and sonographic fetal structural survey at 18 to 22 weeks-all of which are designed to give a woman an adjusted (more accurate) estimate of having an aneuploid fetus using as baseline her a priori age-related risk. Ultrasound and maternal serum analysis are considered screening procedures and both require follow up by CVS or amniocentesis in screen-positive cases for a definitive diagnosis of a chromosome abnormality in the fetus. The ability to isolate fetal cells and fetal DNA from maternal blood during pregnancy has opened up exciting opportunities for improved noninvasive prenatal testing (NIPT). Direct analysis of fetal cells from maternal circulation has been challenging given the scarcity of fetal cells in maternal blood (1:10,000-1:1,000,000) and the focus has shifted to the analysis of cell-free fetal DNA, which is found at a concentration almost 25 times higher than that

    Full Text Available OBJECTIVE: The aim of the study was to investigate the association between prenatal exposure to AEDs and the risk of dental agenesis and to differentiate between the possible effects of the different drugs used. METHODS: Data on 214 exposed and 255 unexposed children, aged 12-18 years, were extracted from the Prescription Database of the Central Denmark Region and North Denmark Region and the Danish Medical Birth Registry. The children's dental charts were examined for the presence of dental agenesis. RESULTS: Overall, children exposed to AED in utero had an increased risk of developing dental agenesis, but as a group, the difference was not significant (OR = 1.7; [95% CI: 0.8-3.6]. The risk of developing dental agenesis was three-fold increased (OR = 3.1; [95% CI: 1.3-7.4] in children exposed to valproate in mono- or in poly-therapy with other AEDs than carbamazepine or oxcarbazepine. The risk was further increased (OR = 11.2; [95% CI: 2.4-51.9] in children exposed to valproate and carbamazepine or oxcarbazepine in combination. CONCLUSIONS: The present study shows that dental agenesis is a potential congenital abnormality that is related to prenatal exposure to valproate, and dental agenesis may be considered a sensitive marker for the teratogenicity of valproate.

    Congenital toxoplasmosis is considered a rare but potentially severe infection. Prenatal education about congenital toxoplasmosis could be the most efficient and least harmful intervention, yet its effectiveness is uncertain. To assess the effects of prenatal education for preventing congenital toxoplasmosis. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (31 May 2015), and reference lists of relevant papers, reviews and websites. Randomized and quasi-randomized controlled trials of all types of prenatal education on toxoplasmosis infection during pregnancy. Cluster-randomized trials were eligible for inclusion. Two review authors independently assessed trials for inclusion and risk of bias, extracted data and checked them for accuracy. Two cluster-randomized controlled trials (RCTs) (involving a total of 5455 women) met the inclusion criteria. The two included trials measured the effectiveness of the intervention in different ways, which meant that meta-analysis of the results was not possible. The overall quality of the two studies, as assessed using the GRADE approach, was low, with high risk of detection and attrition bias in both included trials.One trial (432 women enrolled) conducted in Canada was judged of low methodological quality. This trial did not report on any of the review's pre-specified primary outcomes and the secondary outcomes reported results only as P values. Moreover, losses to follow-up were high (34%, 147 out of 432 women initially enrolled). The authors concluded that prenatal education can effectively change pregnant women's behavior as it increased pet, personal and food hygiene. The second trial conducted in France was also judged of low methodological quality. Losses to follow-up were also high (44.5%, 2233 out of 5023 women initially enrolled) and differential (40% in the intervention group and 52% in the control group). The authors concluded that prenatal education for congenital toxoplasmoses has a

    Objectives The broad maternal and child health community has witnessed increased attention to the entire continuum of reproductive and perinatal health concerns over the past few years. However, both recent discouraging trends in prenatal care access and utilization and a renewed understanding of prenatal care as a critical anchor of the reproductive/perinatal health continuum for women who do get pregnant demand a new effort to focus on the prenatal period as a gateway for maternal and infant health. Methods This commentary: describes the Medicaid expansions and the momentum for universal access to prenatal care of the 1980-1990s; examines the pivot away from this goal and its aftermath; provides a rationale for why renewed attention to prenatal care and the prenatal period is essential; and, explores the potential focus of an updated prenatal care agenda. Conclusion We conclude that increasing women's access to high quality prenatal care will require substantial effort at the clinical, community, policy, and system levels. Only when attention is paid to all phases of the reproductive/perinatal health continuum with an emphasis on continuity between all periods, and on the social determinants that affect health and well-being, will our nation be able to ensure the health of all women across the life course (whether or not they ever become mothers), while simultaneously fulfilling our nation's promise that all children-no matter their income or race/ethnicity-will have the opportunity to be born well.

    Organic solvents have become ubiquitous in our environment and are essential for industry. Many women of reproductive age are increasingly exposed to solvents such as toluene in occupational settings (ie, long-term, low-concentration exposures) or through inhalant abuse (eg, episodic, binge exposures to high concentrations). The risk for teratogenic outcome is much less with low to moderate occupational solvent exposure compared with the greater potential for adverse pregnancy outcomes, developmental delays, and neurobehavioral problems in children born to women exposed to high concentrations of abused organic solvents such as toluene, 1,1,1-trichloroethane, xylenes, and nitrous oxide. Yet the teratogenic effects of abuse patterns of exposure to toluene and other inhalants remain understudied. We briefly review how animal models can aid substantially in clarifying the developmental risk of exposure to solvents for adverse biobehavioral outcomes following abuse patterns of use and in the absence of associated health problems and co-drug abuse (eg, alcohol). Our studies also begin to establish the importance of dose (concentration) and critical perinatal periods of exposure to specific outcomes. The present results with our clinically relevant animal model of repeated, brief, high-concentration binge prenatal toluene exposure demonstrate the dose-dependent effect of toluene on prenatal development, early postnatal maturation, spontaneous exploration, and amphetamine-induced locomotor activity. The results imply that abuse patterns of toluene exposure may be more deleterious than typical occupational exposure on fetal development and suggest that animal models are effective in studying the mechanisms and risk factors of organic solvent teratogenicity.

    Full Text Available Maternal markers are widely used to screen for fetal neural tube defects (NTDs, chromosomal abnormalities and cardiac defects. Some are beginning to broaden prenatal screening to include pregnancy complications such as pre-eclampsia. The methods initially developed for NTDs using a single marker have since been built upon to develop high performance multi-maker tests for chromosomal abnormalities. Although cell-free DNA testing is still too expensive to be considered for routine application in public health settings, it can be cost-effective when used in combination with existing multi-maker marker tests. The established screening methods can be readily applied in the first trimester to identify pregnancies at high risk of pre-eclampsia and offer prevention though aspirin treatment. Prenatal screening for fragile X syndrome might be adopted more widely if the test was to be framed as a form of maternal marker screening.

    Full Text Available Skeletal dysplasias are a group of diseases with a wide spectrum related to bone and cartilage. Some forms are lethal whereas some forms have milder clinical progression. Prenatal diagnosis of skeletal dysplasias may be possible especially when there is an index case in the family. Ultrasonography plays the central role in prenatal diagnosis and most common sonographic features are angulation of long bones, bending of femur or bowing signin the long bones. We present a case whose follow up for fetal short extremities ended with termination of pregnancy. The differential diagnosis is hard and depend especially on the fetal x-ray. Final diagnosis was lethal type osteogenesis imperfecta.

    Prenatal medicine strives to reveal hereditary disorders and congenital malformations before delivery. The application of RIA significantly widened the spectrum of available diagnostic possibilities. We first focused our attention on determining alpha-1-fetoprotein in the amniotic fluid and the serum. We used the results of 33 examinations of the amniotic fluid and 100 samples of the blood serum to compile a graph of physiological values during pregnancy. The graph is used in assessing clinical samples in suspect congenital disorders of neural tube closure and other malformations. In the last two years we have tested testosterone determination in the amniotic fluid to ascertain prenatally the fetal sex in early pregnancy. The results were satisfactory and agreed in 70.6%.

    Research suggests that genetic, prenatal, endocrine, and parenting influences across development individually contribute to internalizing and externalizing problems in children. The present study tests the combined contributions of genetic risk for psychopathology, prenatal environments (maternal drug use and internalizing symptoms), child cortisol at age 4.5 years, and overreactive parenting influences across childhood on 6-year-old children’s internalizing and externalizing problems. We used data from an adoption design that included 361 domestically adopted children and their biological and adopted parents prospectively followed from birth. Only parenting influences contributed (independently) to externalizing problems. However, genetic influences were indirectly associated with internalizing problems (through increased prenatal risk and subsequent morning cortisol), and parenting factors were both directly and indirectly associated with internalizing problems (through morning cortisol). Results suggest that prenatal maternal drug use/symptoms and children’s morning cortisol levels are mechanisms of genetic and environmental influences on internalizing problems, but not externalizing problems, in childhood.

    Objective: Ovarian cysts are the most frequently encountered intra-abdominal masses in females in utero. They may, at times, require perinatal intervention. Using magnetic resonance imaging (MRI) as an adjunct to ultrasonography (US) in prenatal diagnosis, we sought to demonstrate the ability to visualize ovarian cysts on prenatal MRI. Materials and methods: This retrospective study included 17 fetal MRI scans from 16 female fetuses (23–37 gestational weeks) with an MRI diagnosis of ovarian cysts after suspicious US findings. A multiplanar MRI protocol was applied to image and to characterize the cysts. The US and MRI findings were compared, and the prenatal findings were compared with postnatal imaging findings or histopathology. Results: Simple ovarian cysts were found in 10/16 cases and complex cysts in 7/16 cases, including one case with both. In 11/16 (69%) cases, US and MRI diagnoses were in agreement, and, in 5/16 (31%) cases, MRI specified or expanded the US diagnosis. In 6/16 cases, postnatal US showed that the cysts spontaneously resolved or decreased in size, and in 1/16 cases, postnatal imaging confirmed a hemorrhagic cyst. In 4/16 cases, the prenatal diagnoses were confirmed by surgery/histopathology, and for the rest, postnatal correlation was not available. Conclusion: Our results illustrate the MRI visualization of ovarian cysts in utero. In most cases, MRI will confirm the US diagnosis. In certain cases, MRI may provide further diagnostic information, additional to US, which is the standard technique for diagnosis, monitoring, and treatment planning.

    Cleft lip and/or palate is the most common congenital craniofacial anomaly. Prenatal diagnosis of the craniofacial anomalies is possible with the advent of newer imaging modalities. The identification of the defect at an early stage in the pregnancy helps the parents to be well informed and counseled regarding the treatment possibilities and outcomes of cleft lip and palate (CLP) treatment. To analyze the psychological effects of prenatal diagnosis of CLP on the parents. PubMed, Cochrane, and Google Scholar searches were made with search strings "prenatal diagnosis cleft lip palate," "antenatal diagnosis," "anomaly scan," "psychological effect cleft lip palate," and "prenatal counseling cleft lip palate." Of the results obtained, studies which evaluated the psychological aspects of parents of cleft children were further included in the study. Electronic search yielded 500 articles after duplication removal. Forty studies concentrated on the results of the scan and their implications predominantly in the diagnosis and management of cleft and other related abnormalities. Eight studies discussed the effects of prenatal diagnosis and counseling on the parents. Prenatal diagnosis enables appropriate and timely counseling of the parents by the cleft team and helps instill a sense of preparedness for the family which highly improves the quality of treatment received by the child enabling a near-to-normal quality and standard of life.

    The majority of pregnant women in the U.S. undergo prenatal ultrasonography and approximately 0.5% of these examinations will detect fetal malformations. Up to one-half of these abnormalities include the genitourinary system and the most common urological finding is hydronephrosis. Some conditions associated with prenatal hydronephrosis portend a poor prognosis, while others can follow a fairly benign course. This review focuses on the definition and prenatal assessment of hydronephrosis, fetal intervention, and postnatal management. PMID:19618087

    During the last years, technical improvements have increased the possibilities in prenatal ultrasound. During the eighties and nineties, fetal malformations were increasingly detected and specified. Since a few years, the measurement of the fetal nuchal translucency between 11 and 14 weeks of gestation has been implemented to calculate the individual risk, in combination with most recent biochemical markers. Today, the sonographic measurement of the nuchal translucency is regarded as a valuable screening tool for chromosomal anomalies in prenatal medicine. Beside standardized examinations, a profound information and counseling of the pregnant women should be emphasized. With the improvement of the specific maternal risk calculation, using the sonographic measurement of the nuchal translucency, the biochemical markers and the maternal age, unnecessary invasive examinations may be prevented and their overall number can significantly be reduced. The same trend is seen in the whole field of prenatal medicine, illustrated by the detection of the fetal rhesus D status from the maternal blood and the use of Doppler ultrasound in the management of fetal anemia.

    Congenital adrenal hyperplasia (CAH) owing to 21-hydroxylase deficiency is a monogenic disorder of adrenal steroidogenesis. To prevent genital ambiguity, in girls, prenatal dexamethasone treatment is administered early in the first trimester. Prenatal genetic diagnosis of CAH and fetal sex determination identify affected female fetuses at risk for genital virilization. Advancements in prenatal diagnosis are owing to improved understanding of the genetic basis of CAH and improved technology. Cloning of the CYP21A2 gene ushered in molecular genetic analysis as the current standard of care. Noninvasive prenatal diagnosis allows for targeted treatment and avoids unnecessary treatment of males and unaffected females. Copyright © 2016 Elsevier Inc. All rights reserved.

    The objectives were to investigate the prevalence of adverse birth outcomes according to maternal age range in the city of Rio de Janeiro, Brazil, in 2002, and to evaluate the association between maternal age range and adverse birth outcomes using additive interaction to determine whether adequate prenatal care can attenuate the harmful effect of young age on pregnancy outcomes. A cross-sectional analysis was performed in women up to 24 years of age who gave birth to live children in 2002 in the city of Rio de Janeiro. To evaluate adverse outcomes, the exposure variable was maternal age range, and the outcome variables were very preterm birth, low birth weight, prematurity, and low 5-minute Apgar score. The presence of interaction was investigated with the composite variable maternal age plus prenatal care. The proportions and respective 95% confidence intervals were calculated for adequate schooling, delivery in a public maternity hospital, and adequate prenatal care, and the outcomes according to maternal age range. The chi-square test was used. The association between age range and birth outcomes was evaluated with logistic models adjusted for schooling and type of hospital for each prenatal stratum and outcome. Attributable proportion was calculated in order to measure additive interaction. Of the 40,111 live births in the sample, 1.9% corresponded to children of mothers from 10-14 years of age, 38% from 15-19 years, and 59.9% from 20-24 years. An association between maternal age and adverse outcomes was observed only in adolescent mothers with inadequate prenatal care, and significant additive interaction was observed between prenatal care and maternal age for all the outcomes. Adolescent mothers and their newborns are exposed to greater risk of adverse outcomes when prenatal care fails to comply with current guidelines.

    Maternal stress is associated with impairments in the neurodevelopment of offspring; however, the effects of the timing of exposure to maternal stress on a child's neurodevelopment are unclear. In 2010, we studied 225 mother-child pairs in Shanghai, recruiting mothers in mid-to-late pregnancy and monitoring offspring from birth until 30 months of age. Maternal stress was assessed prenatally (at 28-36 weeks of gestation) and postnatally (at 24-30 months postpartum) using the Symptom-Checklist-90-Revised Scale (SCL-90-R) and Life-Event-Stress Scale to evaluate mothers' emotional stress and life event stress levels, respectively. Children's cognition and temperament were assessed at 24-30 months of age using the Gesell Development Scale and Toddler Temperament Scale, respectively. Multi-variable linear regression models were used to associate prenatal and postnatal stress with child cognitive and temperamental development. Maternal prenatal and postnatal Global Severity Index (GSI) of SCL-90-R were moderately correlated (ICC r=0.30, Ptoddlers' gross motor, fine motor, adaptive and social behavior development independently of postnatal GSI, while the increase in postnatal GSI was associated with changes in multiple temperament dimensions independently of prenatal GSI. The effects of prenatal and postnatal depression scores of SCL-90-R were similar to those of GSI. Relatively small sample size. Compared with postnatal exposure, children's cognitive development may be more susceptible to prenatal exposure to maternal emotional stress, whereas temperamental development may be more affected by postnatal exposure to maternal emotional stress compared with prenatal exposure.

    This is the first nationwide register-based study to examine the relationship between prenatal maternal smoking and Tourette syndrome. A total of 767 children diagnosed with Tourette syndrome were identified from the Finnish Hospital Discharge Register. Each case was matched to four controls. Information on maternal smoking during pregnancy was obtained from the Finnish Medical Birth Register. Conditional logistic regression models were used for statistical analyses. Prenatal maternal smoking was associated with Tourette syndrome when comorbid with ADHD (OR 4.0, 95 % CI 1.2-13.5, p = 0.027 for exposure during first trimester, OR 1.7, 95 % CI, 1.05-2.7, p = 0.031 for exposure for the whole pregnancy). There was no association between maternal smoking during pregnancy and Tourette syndrome without comorbid ADHD (OR 0.5, 95 % CI 0.2-1.3, p = 0.166, OR 0.9, 95 % CI 0.7-1.3, p = 0.567). Further research is needed to elucidate the mechanisms behind the association between prenatal maternal smoking and Tourette syndrome with comorbid ADHD.

    International studies suggest that low dose prenatal methylmercury exposure (>29 nmol/L) has long-term adverse neurocognitive effects. There is evidence that the majority of children in Hong Kong exceed this level as a result of high fish consumption of mothers during pregnancy. To study whether there are any associations between low-dose prenatal methylmercury exposure and neurocognitive outcomes in Hong Kong children. All 1057 children from the original birth cohort were eligible for entry into the study, except children with conditions that would affect neurocognitive development, but were unrelated to methylmercury exposure. Subjects were assessed by a wide panel of tests covering a broad range of neurocognitive functions: Hong Kong Wechsler Intelligence Scale for Children (HK-WISC), Hong Kong List Learning Test (HKLLT), Tests of Everyday Attention for Children (TEACH), Boston Naming Test, and Grooved Pegboard Test. 608 subjects were recruited (median age 8.2 years, IQR 7.3, 8.8; 53.9% boys). After correction by confounders including child age and sex, multivariate analysis showed that cord blood mercury concentration was significantly associated with three subtests: Picture Arrangement of HK-WISC (coefficient -0.944, P=0.049) and Short and Long Delay Recall Difference of the HKLLT (coefficient -1.087, P=0.007 and coefficient -1.161, P=0.005, respectively), i.e., performance worsened with increasing prenatal methylmercury exposure in these subtests. Small, but statistically significant adverse associations between prenatal methylmercury exposure and long-term neurocognitive effects (a visual sequencing task and retention ability of verbal memory) were found in our study. These effects are compatible with findings of studies with higher prenatal methylmercury exposure levels and suggest that safe strategies to further reduce exposure levels in Hong Kong are desirable.

  9. Research review: maternal prenatal distress and poor nutrition - mutually influencing risk factors affecting infant neurocognitive development.

    2013-02-01

    Accumulating data from animal and human studies indicate that the prenatal environment plays a significant role in shaping children's neurocognitive development. Clinical, epidemiologic, and basic science research suggests that two experiences relatively common in pregnancy - an unhealthy maternal diet and psychosocial distress - significantly affect children's future neurodevelopment. These prenatal experiences exert their influence in the context of one another and yet, almost uniformly, are studied independently. In this review, we suggest that studying neurocognitive development in children in relation to both prenatal exposures is ecologically most relevant, and methodologically most sound. To support this approach, we selectively review two research topics that demonstrate the need for dual exposure studies, including exemplar findings on (a) the associations between pregnant women's inadequate maternal intake of key nutrients - protein, fat, iron, zinc, and choline - as well as distress in relation to overlapping effects on children's neurocognitive development; and (b) cross-talk between the biology of stress and nutrition that can amplify each experience for the mother and fetus,. We also consider obstacles to this kind of study design, such as questions of statistical methods for 'disentangling' the exposure effects, and aim to provide some answers. Studies that specifically include both exposures in their design can begin to determine the relative and/or synergistic impact of these prenatal experiences on developmental trajectories - and thereby contribute most fully to the understanding of the early origins of health and disease. © 2012 The Author.

    2017-01-01

    Glucocorticoids (cortisol in humans) are the end product of the hypothalamic-pituitary-adrenocortical (HPA) axis and are proposed as a key mechanism for programming fetal brain development. The present prospective longitudinal study evaluates the association between prenatal maternal cortisol concentrations and child neurodevelopment. Participants included a low risk sample of 91 mother-child pairs. Prenatal maternal plasma cortisol concentrations were measured at 19 and 31 gestational weeks. Brain development and cognitive functioning were assessed when children were 6-9 years of age. Structural magnetic resonance imaging scans were acquired and cortical thickness was determined. Child cognitive functioning was evaluated using standardized measures (Wechsler Intelligence Scale for Children IV and Expressive Vocabulary Test, Second Edition). Higher maternal cortisol concentrations during the third trimester were associated with greater child cortical thickness primarily in frontal regions. No significant associations were observed between prenatal maternal cortisol concentrations and child cortical thinning. Elevated third trimester maternal cortisol additionally was associated with enhanced child cognitive performance. Findings in this normative sample of typically developing children suggest that elevated maternal cortisol during late gestation exert lasting benefits for brain development and cognitive functioning 6-9 years later. The benefits of fetal exposure to higher maternal cortisol during the third trimester for child neurodevelopment are consistent with the role cortisol plays in maturation of the human fetus. It is plausible that more extreme elevations in maternal cortisol concentrations late in gestation, as well as exposure to pharmacological levels of synthetic glucocorticoids, may have neurotoxic effects on the developing fetal brain.

  14. Toward healthy offspring: Some origins of prenatal testing in Spain

    Directory of Open Access Journals (Sweden)

    2008-06-01

    Full Text Available This paper deals with prenatal diagnosis practices in Spain. For pursuing this aim it reviews both literature on the origins of these practices in foreign countries as well as some of the early publications by Spanish practitioners. Those publications appeared to be connected to previous genetic testing in children such as the case of Down syndrome. Socio-political norms and values of Franco’s regime together with clinicians’ interests on introducing new testing techniques resulted in the stabilization of these practices associated to a reconceptualisation of pregnancy. Although prenatal diagnosis techniques made the body of pregnant women invisible, women’s bodies remained at the core of the technicalisation of contemporary reproductive options.

    Este trabajo reflexiona sobre las prácticas de diagnóstico prenatal en España. Con este fin se manejan tanto bibliografía sobre los orígenes de estas prácticas en otros países como datos encontrados en las primeras publicaciones al respecto de especialistas de nuestro país. Estas publicaciones se relacionan también con algunas previas sobre diagnóstico genético en la clínica en el caso del síndrome de Down. Se sugiere que las normas sociopolíticas propias de la dictadura de Franco se combinaron con la difusión de técnicas desarrolladas en el extranjero para estabilizar prácticas médicas asociadas a una reconceptualización del embarazo. Las técnicas de diagnóstico prenatal, pese a invisibilizar el cuerpo de las mujeres, mantienen a este en el centro de la tecnificación de las opciones reproductivas contemporáneas.

    hydronephrosis were studied. The maternofetal ultrasound showed a double excretory system. To this end, all the newborns and infants with prenatally detected hydronephrosis and double excretory system diagnosed before or after birth were followed up by evolutive renal ultrasonography, micturition urethrocystography, static or dynamic scintigraphy and, in some cases, by excretory urogram. Double excretory system was found in 7 of the 182 patients (3.8 % with abnormalities of the urinary tract diagnosed before birth. Diagnosis was prenatal in just one of the fetuses (31 weeks of pregnancy. Hydronephrotic dilatation was mild in two fetuses and severe in five. Hydronephrosis had different causes. Upper polar nephrectomy was performed in those cases of ureteral ectopy and obstructed upper ureter, reimplantation in one ureterocele, whereas in another it was confirmed the spontaneous rupture by endoscopy. The rest of the patients were symptomatically treated. The hydronephrosis detected before birth by maternofetal ultrasonography may be associated with a double excretory system. Hydronephrotic dilatation associated with a double excretory system may have different causes, and it is necessary to study carefully and systematically these children and to treat them adequately, since each of them may need a different conduct.

    The radiopharmaceutical administration with diagnostic or therapeutic purpose during pregnancy implies a prenatal radiation dose. The dose assessment and the evaluation of the radiological risks become relevant due to the great radiosensitivity of the fetal tissues in development. This paper is a revision of the available data for estimating fetal doses in the cases of the more frequently used radiopharmaceuticals in nuclear medicine, taking into account recent investigation in placental crossover. The more frequent diagnostic and therapeutic procedures were analyzed according to the radiation doses implied. (author) [es

    Per- and polyfluoroalkyl substances (PFASs) are suspected developmental toxicants, but epidemiological evidence on neurodevelopmental effects of PFAS exposure is inconsistent. We examined associations of prenatal and childhood PFAS exposure with performance on assessments of cognition in children. We included mother-child pairs from Project Viva, a longitudinal Boston-area birth cohort enrolled during 1999-2002. We quantified concentrations of eight PFASs, including perfluorooctane sulfonate (PFOS), perfluorooctanoate (PFOA), and perfluorohexane sulfonate (PFHxS), in plasma collected from women during pregnancy (median 9.7 weeks gestation) and from children at a visit in mid-childhood (median age 7.7 years). In early childhood (median age 3.2 years) we administered standardized assessments of visual motor skills and vocabulary comprehension, and in mid-childhood we assessed visual motor skills, visual memory, and verbal and non-verbal intelligence. Using multivariable regression, we estimated associations of prenatal and childhood PFAS plasma concentrations with children's cognitive assessment scores, adjusted for relevant covariates including breastfeeding, maternal intelligence, parental education, and household income. Samples sizes ranged from 631 to 971, depending on analysis. Prenatal PFAS concentrations were associated with both better and worse cognitive performance; children with top quartile prenatal concentrations of some PFASs had better visual motor abilities in early childhood and non-verbal IQ and visual memory in mid-childhood, while children with upper quartile prenatal PFOA and PFOS had lower mid-childhood visual-motor scores. In cross-sectional analyses of mid-childhood PFAS concentrations and cognitive assessments, visual-motor scores on the Wide Range Assessment of Visual Motor Abilities (WRAVMA) (standardized mean = 100, standard deviation = 15) were lower among children with higher PFHxS (fourth quartile (Q4) vs. Q1: -5.0, 95

These threshold doses are generally above the exposures from medical diagnostic procedures. The quality and extent of radiation effects are very much dependent on the developmental stage during which an exposure takes place and on the radiation dose. An exposure during the preimplantation period will cause lethality. Malformations are usually induced after exposures during the major organogenesis. Growth retardation is also possible during the late organogenesis and foetal periods. The lower limits of threshold doses for these effects are in the range of 100 mGy. A radiation exposure during the early foetal period can lead to severe mental retardation and impairment of intelligence. There are very serious effects with radiation doses above 0.3 Gy. Carcinogenesis can apparently occur after radiation exposures during the total prenatal development period. The radiation risk factor up to now has not been clear, but it seems that it is in the range of risk factors for cancer that are observed after exposures during childhood. For radiation doses that are used in radiological diagnostics the risk is zero or very low. A termination of pregnancy after doses below 100 mGy should not be considered. (author)

    The effectiveness of prenatal treatment to prevent serious neurological sequelae (SNSD) of congenital toxoplasmosis is not known. Congenital toxoplasmosis was prospectively identified by universal prenatal or neonatal screening in 14 European centres and children were followed for a median of 4 years. We evaluated determinants of postnatal death or SNSD defined by one or more of functional neurological abnormalities, severe bilateral visual impairment, or pregnancy termination for confirmed congenital toxoplasmosis. Two-thirds of the cohort received prenatal treatment (189/293; 65%). 23/293 (8%) fetuses developed SNSD of which nine were pregnancy terminations. Prenatal treatment reduced the risk of SNSD. The odds ratio for prenatal treatment, adjusted for gestational age at maternal seroconversion, was 0.24 (95% Bayesian credible intervals 0.07-0.71). This effect was robust to most sensitivity analyses. The number of infected fetuses needed to be treated to prevent one case of SNSD was three (95% Bayesian credible intervals 2-15) after maternal seroconversion at 10 weeks, and 18 (9-75) at 30 weeks of gestation. Pyrimethamine-sulphonamide treatment did not reduce SNSD compared with spiramycin alone (adjusted odds ratio 0.78, 0.21-2.95). The proportion of live-born infants with intracranial lesions detected postnatally who developed SNSD was 31.0% (17.0%-38.1%). The finding that prenatal treatment reduced the risk of SNSD in infected fetuses should be interpreted with caution because of the low number of SNSD cases and uncertainty about the timing of maternal seroconversion. As these are observational data, policy decisions about screening require further evidence from a randomized trial of prenatal screening and from cost-effectiveness analyses that take into account the incidence and prevalence of maternal infection.

    Methylmercury (MeHg) is a developmental neurotoxicant; exposure results principally from consumption of seafood contaminated by mercury (Hg). In this analysis, the burden of mental retardation (MR) associated with methylmercury exposure in the 2000 U.S. birth cohort is estimated, and the portion of this burden attributable to mercury (Hg) emissions from coal-fired power plants is identified. The aggregate loss in cognition associated with MeHg exposure in the 2000 U.S. birth cohort was estimated using two previously published dose-response models that relate increases in cord blood Hg concentrations with decrements in IQ. MeHg exposure was assumed not to be correlated with native cognitive ability. Previously published estimates were used to estimate economic costs of MR caused by MeHg. Downward shifts in IQ resulting from prenatal exposure to MeHg of anthropogenic origin are associated with 1,566 excess cases of MR annually (range: 376-14,293). This represents 3.2% of MR cases in the US (range: 0.8%-29.2%). The MR costs associated with decreases in IQ in these children amount to $2.0 billion/year (range: $0.5-17.9 billion). Hg from American power plants accounts for 231 of the excess MR cases year (range: 28-2,109), or 0.5% (range: 0.06%-4.3%) of all MR. These cases cost $289 million (range: $35 million-2.6 billion). Toxic injury to the fetal brain caused by Hg emitted from coal-fired power plants exacts a significant human and economic toll on American children.

    Full Text Available BackgroundThe prenatal ultrasound detection of cleft lip with or without cleft palate (CL/P and its continuous management in the prenatal, perinatal, and postnatal periods using a multidisciplinary team approach can be beneficial for parents and their infants. In this report, we share our experiences with the prenatal detection of CL/P and the multidisciplinary management of this malformation in our institution's Congenital Disease Center.MethodsThe multidisciplinary team of the Congenital Disease Center for mothers of children with CL/P is composed of obstetricians, plastic and reconstructive surgeons, pediatricians, and psychiatrists. A total of 11 fetuses were diagnosed with CL/P from March 2009 to December 2013, and their mothers were referred to the Congenital Disease Center of our hospital. When CL/P is suspected in the prenatal ultrasound screening examination, the pregnant woman is referred to our center for further evaluation.ResultsThe abortion rate was 28% (3/11. The concordance rate of the sonographic and final diagnoses was 100%. Ten women (91% reported that they were satisfied with the multidisciplinary management in our center.ConclusionsAlthough a child with a birth defect is unlikely to be received well, the women whose fetuses were diagnosed with CL/P on prenatal ultrasound screening and who underwent multidisciplinary team management were more likely to decide to continue their pregnancy.

    Hypertensive disorders of pregnancy (HDP) are the most important cause of maternal and fetal death and pregnancy complications in Latin America and the Caribbean. The objective of this study was to characterize the epidemiological profile of women with HDP admitted to a Brazilian tertiary reference hospital, and to evaluate maternal and fetal outcome in each HDP and the impact of prenatal care on the maternal and fetal outcome. HDP in 1501 women were classified according to usual definitions as chronic hypertension (n = 564), pre-eclampsia (n = 579), eclampsia (n = 74) and pre-eclampsia/eclampsia superimposed on chronic hypertension (n = 284). Adverse maternal and fetal outcomes registered as maternal death and near miss and fetal outcomes documented as stillbirth, neonatal death and newborn respiratory complications were compiled. Prenatal care was classified as complete (⩾ 6 visits), incomplete (prenatal care or prenatal not done had progressive higher mortality rates and greater frequency of near miss cases, and their children had higher mortality rates. In a tertiary reference hospital, eclampsia and chronic hypertension superimposed on pre-eclampsia are associated with a worst outcome for mothers and fetuses, whereas complete prenatal care is associated with a better maternal and fetal outcome in HDP. © The Author(s), 2015.

  14. Characterization of the cognitive impairments induced by prenatal exposure to stress in the rat

    Full Text Available We have previously shown that male rats exposed to gestational stress exhibit phenotypes resembling what is observed in schizophrenia, including hypersensitivity to amphetamine, blunted sensory gating, disrupted social behavior, impaired stress axis regulation, and aberrant prefrontal expression of genes involved in synaptic plasticity. Maternal psychological stress during pregnancy has been associated with adverse cognitive outcomes among children, as well as an increased risk for developing schizophrenia, which is characterized by significant cognitive deficits. We sought to characterize the long-term cognitive outcome of prenatal stress using a preclinical paradigm, which is readily amenable to the development of novel therapeutic strategies. Rats exposed to repeated variable prenatal stress during the third week of gestation were evaluated using a battery of cognitive tests, including the novel object recognition task, cued and contextual fear conditioning, the Morris water maze, and iterative versions of a paradigm in which working and reference memory for both objects and spatial locations can be assessed (the ‘Can Test’. Prenatally stressed males were impaired relative to controls on each of these tasks, confirming the face validity of this preclinical paradigm and extending the cognitive implications of prenatal stress exposure beyond the hippocampus. Interestingly, in experiments where both sexes were included, the performance of females was found to be less affected by prenatal stress compared to that of males. This could be related to the finding that women are less vulnerable than men to schizophrenia, and merits further investigation.

    Full Text Available Congenital malformations are one of the main causes of high infant mortality and disability from childhood. Medical and genetic counseling is an important integral part of prenatal diagnosis. Aim. The experience of the work of prenatal consultation at the clinic of Zaporizhzhya Regional Center of Human Reproduction for the 2011- 2015 years has been analyzed. Modern methods of prenatal diagnosis, including mass and selective testing of pregnant women on birth defects and chromosomal abnormalities by ultrasound examination and evaluation of maternal serum markers, as well as prenatal, cytogenetic diagnosis of chromosomal diseases in high-risk groups have been used for the early detection and prevention of birth of children with hereditary diseases in the Zaporizhzhia region. Methods and results. 2,528 Pregnant women with suspected congenital malformations of the fetus have been examined. To adequately assess the perinatal prognosis and develop tactics of pregnancy in the early neonatal period the diagnosis of pregnant women included consultation of geneticist, obstetrician - gynecologist, others specialists. Malformations of the fetus have been identified in 1.435 pregnant women. Conclusions. To identify chromosomal aberrations and congenital malformations in the fetus the prenatal consultation defines: the forecast for the life and health of the child, the tactics of pregnancy and birth, postnatal correction. Multiple malformations in the fetus and congenital central nervous system development occupy the first place in the structure of abortion during the observed period (2011-2015 years.

    MECP2 duplication results in a well-recognised syndrome in 100% of affected male children; this syndrome is characterised by severe neurodevelopmental disabilities and recurrent infections. However, no sonographic findings have been reported for affected foetuses, and prenatal molecular diagnosis has not been possible for this disease due to lack of prenatal clinical presentation. In this study, we identified a small duplication comprising the MECP2 and L1CAM genes in the Xq28 region in a patient from a family with severe X-linked mental retardation and in a prenatal foetus with brain structural abnormalities. Using high-resolution chromosome microarray analysis (CMA) to screen 108 foetuses with congenital structural abnormalities, we identified additional three foetuses with the MECP2 duplication. Our study indicates that ventriculomegaly, hydrocephalus, agenesis of the corpus callosum, choroid plexus cysts, foetal growth restriction and hydronephrosis might be common ultrasound findings in prenatal foetuses with the MECP2 duplication and provides the first set of prenatal cases with MECP2 duplication, the ultrasonographic phenotype described in these patients will help to recognise the foetuses with possible MECP2 duplication and prompt the appropriate molecular testing.

    Toxoplasmosis is an infection that affects almost a third of the world population. In adults, it is often asymptomatic, although having important manifestation in children- infected by placental transmission. The prenatal is an important moment, requiring actions in women's care during pregnancy, in order to prevent diseases that could compromise the mother and the child's life. This is a descriptive study of qualitative approach aimed to understand the perception of nurses and pregnant women about toxoplasmosis during primary - prenatal care. The study was conducted in five selected primary health care units, in the municipality of São Luis - MA. The sample consisted of 15 nurses working in nursing consultation and 15 pregnant women attended in prenatal care. For data collection, a semi-structured questionnaire and an interview guide covering issues related to knowledge and conduct on toxoplasmosis were used. For analysis, the content analysis technique was used. The answers were transcribed, organized and grouped thematically, where the following categories emerged: knowledge about examination requests; knowledge about toxoplasmosis; guidance during prenatal consultation; knowledge of nurses about the avidity test; procedures and guidelines on reagent cases. Pregnant women showed unawareness about toxoplasmosis and its effects. Nurses, although having basic knowledge about the subject, showed little applicability regarding pregnant women's guidance. The nurse plays an important role in educational activities regarding pregnant women, contributing to the quality of prenatal care. Pregnant women were shown to have some knowledge about toxoplasmosis, although they said they did not have assurance about prevention.

    Experimental animal studies and limited epidemiologic evidence suggest that prenatal exposure to phthalates may be obesogenic, with potential sex-specific effects of phthalates having anti-androgenic activity. We aimed to assess associations between prenatal phthalate exposures and childhood fat mass in a prospective cohort study. We measured phthalate metabolite concentrations in third-trimester maternal urine in a cohort of women enrolled in New York City between 1998 and 2002 (n = 404). Among 180 children (82 girls and 98 boys), we evaluated body composition using a Tanita scale at multiple follow-up visits between ages 4 and 9 years (363 total visits). We estimated associations of standard deviation differences or tertiles of natural log phthalate metabolite concentrations with percent fat mass using linear mixed-effects regression models with random intercepts for repeated outcome measurements. We assessed associations in multiple metabolite models and adjusted for covariates including prepregnancy body mass index, gestational weight gain, maternal smoking during pregnancy, and breastfeeding. We did not observe associations between maternal urinary phthalate concentrations and percent body fat in models examining continuous exposures. Fat mass was 3.06% (95% CI: -5.99, -0.09%) lower among children in the highest tertile of maternal urinary concentrations of summed di(2-ethylhexyl) phthalate (ΣDEHP) metabolites than in children in the lowest tertile. Though estimates were imprecise, there was little evidence that associations between maternal urinary phthalate concentrations and percent fat mass were modified by child's sex. Prenatal phthalate exposures were not associated with increased body fat among children 4-9 years of age, though high prenatal DEHP exposure may be associated with lower fat mass in childhood.

    Full Text Available Prior research reports inverse associations between maternal prenatal urinary phthalate metabolite concentrations and mental and motor development in preschoolers. No study evaluated whether these associations persist into school age.In a follow up of 328 inner-city mothers and their children, we measured prenatal urinary metabolites of di-n-butyl phthalate (DnBP, butylbenzyl phthalate (BBzP, di-isobutyl phthalate (DiBP, di-2-ethylhexyl phthalate and diethyl phthalate in late pregnancy. The Wechsler Intelligence Scale for Children, 4th edition was administered at child age 7 years and evaluates four areas of cognitive function associated with overall intelligence quotient (IQ.Child full-scale IQ was inversely associated with prenatal urinary metabolite concentrations of DnBP and DiBP: b = -2.69 (95% confidence interval [CI] = -4.33, -1.05 and b = -2.69 (95% CI = -4.22, -1.16 per log unit increase. Among children of mothers with the highest versus lowest quartile DnBP and DiBP metabolite concentrations, IQ was 6.7 (95% CI = 1.9, 11.4 and 7.6 (95% CI = 3.2, 12.1 points lower, respectively. Associations were unchanged after control for cognition at age 3 years. Significant inverse associations were also seen between maternal prenatal metabolite concentrations of DnBP and DiBP and child processing speed, perceptual reasoning and working memory; DiBP and child verbal comprehension; and BBzP and child perceptual reasoning.Maternal prenatal urinary metabolite concentrations measured in late pregnancy of DnBP and DiBP are associated with deficits in children's intellectual development at age 7 years. Because phthalate exposures are ubiquitous and concentrations seen here within the range previously observed among general populations, results are of public health significance.

    Recent rodent studies have demonstrated that parental cocaine exposure can influence offspring behavior, supporting the idea that environmental insults can impact subsequent generations. However, studies on the effects of paternal cocaine exposure are limited and multiple inconsistencies exist. In the current study, we behaviorally characterize the effects of paternal cocaine exposure in a C57BL/6J intergenerational mouse model. Male sires were administered cocaine hydrochloride (20mg/kg) or saline (0.01mL/g) once a day for 75days, and bred with drug naïve females twenty-four hours after the final injection. Offspring, separated by sex, were tested in a battery of behaviors. We found that paternal cocaine exposure altered sensitivity to the rewarding and stimulant effects of psychostimulants and natural reward (sucrose) in female offspring; female cocaine-sired offspring showed blunted cocaine preference using cocaine conditioned place preference (CPP) at a low dose (5mg/kg), but displayed similar preference at a higher dose (10mg/kg) compared to saline-sired controls. Additionally, cocaine-sired female offspring exhibited higher psychomotor sensitivity to cocaine (10mg/kg) and amphetamine (2mg/kg) and consumed more sucrose. Cocaine-sired males exhibited increased psychomotor effects of cocaine and amphetamine. Male offspring also displayed an anxiety-like phenotype. No effect of paternal cocaine exposure was observed on depressive-like, learning and memory or social behavior in male or female offspring. Collectively, our findings show that paternal, chronic cocaine exposure induces intergenerational behavioral effects in male and female offspring with greatest impact on sensitivity to psychostimulants and sucrose in females.

    To measure the effect of access to prenatal care on unauthorized and low-income, new legal permanent resident immigrant women and their offspring. We used a difference-in-differences design that leverages the staggered rollout of Emergency Medicaid Plus by county from 2008 to 2013 as a natural experiment to estimate the effect on health service utilization for women and health outcomes for their infants. Regular Medicaid pregnancies were used as an additional control in a triple difference design. Our sample included pregnancies covered by Emergency Medicaid (35,182), Emergency Medicaid Plus (12,510), and Medicaid (166,054). After expansion of access to prenatal care, there was an increase in prenatal visits (7.2 more visits, 95% CI 6.45-7.96), receipt of adequate prenatal care (28% increased rate, CI 26-31), rates of diabetes screening (61% increased rate, CI 56-66), and fetal ultrasonograms (74% increased rate, CI 72-76). Maternal access to prenatal care was also associated with an increased number of well child visits (0.24 more visits, CI 0.07-0.41), increased rates of recommended screenings and vaccines (0.04 increased probability, CI 0.002-0.074), and reduced infant mortality (-1.01/1,000, CI -1.42 to -0.60) and rates of extremely low birth weight (less than 1,000 g) (-1.33/1,000, CI -2.44 to -0.21). Our results provide evidence of increased utilization and improved health outcomes for unauthorized immigrants and their children who are U.S. citizens after introduction of prenatal care expansion in Oregon. This study contributes to the debate around reauthorization of the Children's Health Insurance Program in 2017.

    Prenatal diagnosis of complex laparoschisis is difficult and yet it is associated with a significantly increased morbidity and mortality. The aim of the study was to define ultrasonographic factor and obstetrical criteria to predicting adverse neonatal outcome. Retrospective cohort study over 10 years, of 35 gastroschisis cases in CHU of Reims (France). The primary outcome was the neonatal death due to gastroschisis. The sonographic markers was bowel dilatation intra- or extra-abdominale, amniotic fluid, intra-uterin growth. The obstetrical criteria was fetal vitality, fetal heart rate, type of delivery, the weight and the term of birth. There were 28 live births, 16 children with favorable outcome, 8 children with adverse perinatal outcome and 4 deaths. There were any sonographic criteria to predicting adverse neonatal outcome. Only the birth weight less than 2000g was associated with an increase gastrointestinal complications (P=0.049). The type of the delivery was not associated with an adverse prenatal outcome. The birth weight less than 2000g seems to be associate with an increase gastrointestinal complications. It is important to fight against prematurity in case of gastroschisis.

    Seizures are a frequent sequela of impaired brain development and can be expected to affect more children with radiation-related brain damage than children without such damage. This report deals with the incidence and type of seizures among survivors prenatally exposed to the atomic bombing of Hiroshima and Nagasaki, and their association with specific stages of prenatal development at the time of irradiation. Fetal radiation dose was assumed to be equal to the dose to the maternal uterus. Seizures here include all references in the clinical record to seizure, epilepsy, or convulsion. Histories of seizures were obtained at biennial routine clinical examinations starting at about the age of 2 years. These clinical records were used to classify seizures as febrile or unprovoked (without precipitating cause). No seizures were ascertained among subjects exposed 0-7 weeks after fertilization at doses higher than 0.10 Gy. The incidence of seizures was highest with irradiation at the eighth through the 15th week after fertilization among subjects with doses exceeding 0.10 Gy and was linearly related to the level of fetal exposure. This obtains for all seizures without regard to the presence of fever or precipitating causes, and for unprovoked seizures. When the 22 cases of severe mental retardation were excluded, the increase in seizures was only suggestively significant and only for unprovoked seizures. After exposure at later stages of development, there was no increase in recorded seizures

    these modified criteria, only 3 patients in each group met criteria but did not receive a shunt. For the revised composite outcome, there was a difference between the prenatal and postnatal surgery groups: 49.5% versus 87.0% (p < 0.0001). There was also a significant reduction in the number of children who had a shunt placed and then required a revision by 1 year of age in the prenatal group (15.4% vs 40.2%, relative risk 0.38 [95% CI 0.22–0.66]). In the prenatal surgery group, 20% of those with ventricle size < 10 mm at initial screening, 45.2% with ventricle size of 10 up to 15 mm, and 79.0% with ventricle size ≥ 15 mm received a shunt, whereas in the postnatal group, 79.4%, 86.0%, and 87.5%, respectively, received a shunt (p = 0.02). Lesion level and degree of hindbrain herniation appeared to have no effect on the eventual need for shunting (p = 0.19 and p = 0.13, respectively). Similar results were obtained for the revised outcome. Conclusions Larger ventricles at initial screening are associated with an increased need for shunting among those undergoing fetal surgery for myelomeningocele. During prenatal counseling, care should be exercised in recommending prenatal surgery when the ventricles are 15 mm or larger because prenatal surgery does not appear to improve outcome in this group. The revised criteria may be useful as guidelines for treating hydrocephalus in this group. PMID:26369371

    Objective: Situs anomalies refer to an abnormal organ arrangement, which may be associated with severe errors of development. Due regard being given to prenatal magnetic resonance imaging (MRI) as an adjunct to ultrasonography (US), this study sought to demonstrate the in utero visualization of situs anomalies on MRI, compared to US. Materials and methods: This retrospective study included 12 fetuses with situs anomalies depicted on fetal MRI using prenatal US as a comparison modality. With an MRI standard protocol, the whole fetus was assessed for anomalies, with regard to the position and morphology of the following structures: heart; venous drainage and aorta; stomach and intestines; liver and gallbladder; and the presence and number of spleens. Results: Situs inversus totalis was found in 3/12 fetuses; situs inversus with levocardia in 1/12 fetuses; situs inversus abdominis in 2/12 fetuses; situs ambiguous with polysplenia in 3/12 fetuses, and with asplenia in 2/12 fetuses; and isolated dextrocardia in 1/12 fetuses. Congenital heart defects (CHDs), vascular anomalies, and intestinal malrotations were the most frequent associated malformations. In 5/12 cases, the US and MRI diagnoses were concordant. Compared to US, in 7/12 cases, additional MRI findings specified the situs anomaly, but CHDs were only partially visualized in six cases. Conclusions: Our initial MRI results demonstrate the visualization of situs anomalies and associated malformations in utero, which may provide important information for perinatal management. Using a standard protocol, MRI may identify additional findings, compared to US, which confirm and specify the situs anomaly, but, with limited MRI visualization of fetal CHDs.

    Prenatal tobacco exposure, through maternal smoking during pregnancy, has been associated with adverse mental health outcomes in childhood. However, the mechanisms by which prenatal tobacco exposure compromises mental health later in life are unclear. We hypothesized that sensitized reactivity to stressful life events in early childhood mediates the effect of prenatal tobacco exposure on mental health outcomes in middle childhood, after accounting for earlier mental health outcomes. Data were from 12,308 mothers and their children drawn from the Avon Longitudinal Study of Parents and Children, a large prospective population-based study. Mothers' self-reports of smoking during pregnancy, mothers' ratings of their child's reactivity to stressful life events, and teachers' and mothers' ratings of the Strengths and Difficulties Questionnaire assessing 5 domains of mental health outcomes were measured. A positive association was found between prenatal tobacco exposure and stress reactivity between the ages of 2 and 6. In turn, stress reactivity was positively associated with peer (isolation), hyperactivity, conduct, and emotional problems (but not prosocial behaviors) between the ages of 7 and 11, after accounting for the mental health outcome at age 4 and other confounders. Heightened stress reactivity in preschool ages mediated the effect of prenatal tobacco exposure on adverse mental health outcomes between the ages of 7 and 11. Interventions to assist children exposed to tobacco smoke during gestation in coping with stressful life events may help mitigate psychiatric symptoms in this population.

    The neonatal line (NNL) is used to distinguish developmental events observed in enamel which occurred before and after birth. However, there are few studies reporting relationship between the characteristics of the NNL and factors affecting prenatal conditions. The aim of the study was to determine prenatal factors that may influence the NNL thickness in human deciduous teeth. The material consisted of longitudinal ground sections of 60 modern human deciduous incisors obtained from full-term healthy children with reported birth histories and prenatal factors. All teeth were sectioned in the labio-lingual plane using diamond blade (Buechler IsoMet 1000). Final specimens were observed using scanning electron microscopy at magnifications 320×. For each tooth, linear measurements of the NNL thickness were taken on its labial surface at the three levels from the cemento-enamel junction. The difference in the neonatal line thickness between tooth types and between males and females was statistically significant. A multiple regression analyses confirmed influence of two variables on the NNL thickness standardised on tooth type and the children's sex (z-score values). These variables are the taking of an antispasmodic medicine by the mother during pregnancy and the season of the child's birth. These two variables together explain nearly 17% of the variability of the NNL. Children of mothers taking a spasmolytic medicine during pregnancy were characterised by a thinner NNL compared with children whose mothers did not take such medication. Children born in summer and spring had a thinner NNL than children born in winter. These results indicate that the prenatal environment significantly contributes to the thickness of the NNL influencing the pace of reaching the post-delivery homeostasis by the newborn's organism.

    Many pregnant women in the United States have suboptimal vitamin D, but the impact on infant development is unclear. Moreover, no pregnancy-specific vitamin D recommendations have been widely accepted. Given the ubiquitous expression of vitamin D receptors in the brain, we investigated the association between early prenatal plasma 25-hydroxyvitamin D (25(OH)D) concentrations and children's social and emotional development in the Newborn Epigenetic Study, a prospective study of pregnancies from 2009 to 2011 in Durham, North Carolina. We measured 25(OH)D concentrations in first or second trimester plasma samples and categorized 25(OH)D concentrations into quartiles. Covariates were derived from maternal questionnaires. Mothers completed the Infant Toddler Social-Emotional Development Assessment when children were 12-24 months of age. We used multivariable linear regression to evaluate associations between 25(OH)D and specific behavior scores, adjusted for season of blood draw, maternal age, education, parity, smoking, marital status, prepregnancy BMI, and infant gender. We investigated effect-measure modification by race/ethnicity. Of the 218 mother-infant pairs with complete data, Black mothers had much lower 25(OH)D concentrations as compared to White and Hispanic mothers. After adjustment, lower prenatal 25(OH)D was associated with slightly higher (less favorable) Internalizing scores among White children, but lower (more favorable) Internalizing scores among Black and Hispanic children. Lower prenatal 25(OH)D also appears to be associated with higher (less favorable) dysregulation scores, though only among White and Hispanic children. Though imprecise, preliminary results warrant further investigation regarding a role for prenatal vitamin D on children's early social and emotional development.

    To evaluate the ultrasonographic characteristic of a rare malformation comples, Cloacal anomaly on prenatal ultrasonography. From March 1991 to July 2001, eight cases with the persistent cloaca (4 cases in female and 1 case in male) and cloacal exstrophy (3 cases) diagnosed by prenatal ultrasound examination were included, and all of them were pathologically confirmed by autopsy. One radiologist retrospectively analyzed the prenatal sonographic images, including the urinary bladder, kidney, pelvic cyst, abdominal wall defect and amount of amniotic fluid. The ultrasonographic diagnosis was established at 21.8 {+-} 7.8 weeks of gestation. The prenatal ultrasonographic findings of the persistent cloaca were absent bladder (n=2), distended bladder (n=2) and small thick bladder (n=1). Sonography of the kidney showed normal (n=2), hydronephrosis (n=1), dysplasia (n=1) and unilateral hydronephrosis with absent contralateral kidney (n=1). Four fetuses showed septated pelvic cyst; three fetuses, oligohydramnios. The prenatal ultrasonographic findings of cloacal exstrophy included absent bladder (n=3), normal kidney (n=1), hydronephrosis (n=1) and absent kidney (n=1). All fetuses with cloacal exstrophy had abdominal wall defect while two of them had oligohydramnios. A prenatal diagnosis of persistent cloaca can be confidently made when there is septated pelvic cyst combined oligohydramnios, sediments within the cyst and intraluminal calcifications. Cloacal exstrophy should be included in diagnosis if there is a low abdominal wall defect with absent urinary bladder.

    Full Text Available This cross-sectional study intended to assess the use of prenatal care according to the family structure in a population with free universal access to prenatal care. In 2005-2006, the Portuguese birth cohort was assembled by the recruitment of puerperae at public maternity wards in Porto, Portugal. In the current analysis, 7,211 were included. Data on socio-demographic characteristics, obstetric history, and prenatal care were self-reported. Single mothers were considered as those whose household composition did not include a partner at delivery. Approximately 6% of the puerperae were single mothers. These women were more likely to have an unplanned pregnancy (OR = 6.30; 95%CI: 4.94-8.04, an inadequate prenatal care (OR = 2.30; 95%CI: 1.32-4.02, and to miss the ultrasound and the intake of folic acid supplements during the first trimester of pregnancy (OR = 1.71; 95%CI: 1.30-2.27; and OR = 1.67; 95%CI: 1.32-2.13, respectively. The adequacy and use of prenatal care was less frequent in single mothers. Educational interventions should reinforce the use and early initiation of prenatal care.

    Considerable animal research and available human studies suggest that psychological distress experienced by mothers during gestation is associated with later neurodevelopmental deficits in offspring; however, little research has examined potential protective factors that might mitigate this risk. The current study examined the impact of maternal prenatal psychological distress during pregnancy on cognitive outcomes in preschoolers (ages 2.5-5 years) and positive parenting as a potential protective factor. Mother-child dyads (N = 162, mean child age = 44 months, 49 % female) were recruited from a longitudinal cohort of women who had previously participated in a study of maternal mood disorders during pregnancy. Maternal prenatal distress was assessed with multiple measures collected throughout pregnancy. During a follow-up visit, mothers were interviewed about their psychological symptoms since the birth of the child, parenting behaviors were recorded during a parent-child interaction, and children's cognitive abilities were measured using the Differential Ability Scales, 2nd Edition. Maternal prenatal distress significantly predicted lower general cognitive abilities; however, this relationship was strongest for children whose mothers exhibited low levels of positive engagement and not significant when mothers exhibited high levels of positive engagement. Results suggest that positive parental engagement can protect against the detrimental effects of maternal prenatal distress on preschoolers' cognitive abilities.

    Parents' representations of their infants consist of parents' subjective experiences of how they perceive their infants. They provide important information about the quality of the parent-infant relationship and are closely related to parenting behavior and infant attachment. Previous studies have shown that parents' representations emerge during pregnancy. However, little is known about prenatal (risk) factors that are related to parents' representations. In a prospective study, 308 mothers and 243 fathers were followed during pregnancy and postpartum. Prenatal risk factors were assessed with an adapted version of the Dunedin Family Services Indicator (T.G. Egan et al., ; R.C. Muir et al., ). At 26 weeks' gestation and 6 months' postpartum, parents' representations of their children were assessed with the Working Model of the Child Interview (C.H. Zeanah, D. Benoit, L. Hirshberg, M.L. Barton, & C. Regan). Results showed stability between pre- and postnatal representations, with fathers having more disengaged representations than did mothers. In addition, prenatal risk factors of parenting problems were associated with the quality of parents' prenatal (only in mothers) and postnatal representations. This study provides valuable information concerning parents at risk of developing nonbalanced representations of their children. In clinical practice, these families could be monitored more intensively and may be supported in developing a more optimal parent-infant relationship. © 2015 Michigan Association for Infant Mental Health.

    Objective To describe the utilization of prenatal care in American Samoan women and to identify socio-demographic predictors of inadequate prenatal care utilization. Methods Using data from prenatal clinic records, women (n=692) were categorized according to the Adequacy of Prenatal Care Utilization Index as having received adequate plus, adequate, intermediate or inadequate prenatal care during their pregnancy. Categorical socio-demographic predictors of the timing of initiation of prenatal care (week of gestation) and the adequacy of received services were identified using one way Analysis of Variance (ANOVA) and independent samples t-tests. Results Between 2001 and 2008 85.4% of women received inadequate prenatal care. Parity (P=0.02), maternal unemployment (P=0.03), and both parents being unemployed (P=0.03) were negatively associated with the timing of prenatal care initation. Giving birth in 2007–2008, after a prenatal care incentive scheme had been introduced in the major hospital, was associated with earlier initiation of prenatal care (20.75 versus 25.12 weeks; Pprenatal care utilization in American Samoa is a major concern. Improving healthcare accessibility will be key in encouraging women to attend prenatal care. The significant improvements in the adequacy of prenatal care seen in 2007–2008 suggest that the prenatal care incentive program implemented in 2006 may be a very positive step toward addressing issues of prenatal care utilization in this population.

  2. Prenatal methadone exposure is associated with altered neonatal brain development

    Directory of Open Access Journals (Sweden)

    Full Text Available Methadone is used for medication-assisted treatment of heroin addiction during pregnancy. The neurodevelopmental outcome of children with prenatal methadone exposure can be sub-optimal. We tested the hypothesis that brain development is altered among newborn infants whose mothers were prescribed methadone.20 methadone-exposed neonates born after 37weeks' postmenstrual age (PMA and 20 non-exposed controls underwent diffusion MRI at mean PMA of 39+2 and 41+1weeks, respectively. An age-optimized Tract-based Spatial Statistics (TBSS pipeline was used to perform voxel-wise statistical comparison of fractional anisotropy (FA data between exposed and non-exposed neonates.Methadone-exposed neonates had decreased FA within the centrum semiovale, inferior longitudinal fasciculi (ILF and the internal and external capsules after adjustment for GA at MRI (p<0.05, TFCE corrected. Median FA across the white matter skeleton was 12% lower among methadone-exposed infants. Mean head circumference (HC z-scores were lower in the methadone-exposed group (−0.52 (0.99 vs 1.15 (0.84, p<0.001; after adjustment for HC z-scores, differences in FA remained in the anterior and posterior limbs of the internal capsule and the ILF. Polydrug use among cases was common.Prenatal methadone exposure is associated with microstructural alteration in major white matter tracts, which is present at birth and is independent of head growth. Although the findings cannot be attributed to methadone per se, the data indicate that further research to determine optimal management of opioid use disorder during pregnancy is required. Future studies should evaluate childhood outcomes including infant brain development and long-term neurocognitive function. Keywords: Prenatal, Methadone, Brain, Neonate, MRI, Opioid

Offspring of rat dams stressed...... of the acoustic startle response. Further, a single aversive life event showed capable of changing the reactivity of prenatally stressed offspring, whereas offspring of dams going through a less stressful gestation was largely unaffected by this event.

    Paracetamol exposure has been positively associated with asthma development. The relative importance of prenatal vs infant exposure and confounding by indication remains elusive. We examined the association of prenatal and infant (first 6 months) paracetamol exposure with asthma development while addressing confounding by indication. We used information from the Norwegian Mother and Child Cohort Study, including 53169 children for evaluation of current asthma at 3 years, 25394 for current asthma at 7 years and 45607 for dispensed asthma medications at 7 years in the Norwegian Prescription Database. We calculated adjusted relative risks (adj. RR) and 95% confidence intervals (CI) using log-binomial regression. There were independent modest associations between asthma at 3 years with prenatal paracetamol exposure (adj. RR 1.13; 95% CI: 1.02-1.25) and use of paracetamol during infancy (adj. RR 1.29; 95% CI: 1.16-1.45). The results were consistent for asthma at 7 years. The associations with prenatal paracetamol exposure were seen for different indications (pain, respiratory tract infections/influenza and fever). Maternal pain during pregnancy was the only indication that showed an association both with and without paracetamol use. Maternal paracetamol use outside pregnancy and paternal paracetamol use were not associated with asthma development. In a secondary analysis, prenatal ibuprofen exposure was positively associated with asthma at 3 years but not asthma at 7 years. This study provides evidence that prenatal and infant paracetamol exposure have independent associations with asthma development. Our findings suggest that the associations could not be fully explained by confounding by indication. © The Author 2016; all rights reserved.

    Marital distress, parental depression, and weak quality of parental representations are all known risk factors for parent-child relationships. However, the relation between marital distress, depressive symptoms, and parents' prenatal representation is uncertain, especially regarding fathers. The present study aimed to explore how mothers' and fathers' prenatal experience of marital distress and depressive symptoms affects the organization of their prenatal representations in late pregnancy. Participants were 153 pregnant couples from a Finnish follow-up study called "Steps to the Healthy Development and Well-being of Children" (H. Lagström et al., ). Marital distress (Revised Dyadic Adjustment Scale; D.M. Busby, C. Christensen, D. Crane, & J. Larson, 1995) and depressive symptoms (Edinburgh Postnatal Depression Scale) were assessed at 20 gestational weeks, and prenatal representations (Working Model of the Child Interview; D. Benoit, K.C.H. Parker, & C.H. Zeanah, 1997; C.H. Zeanah, D. Benoit, M. Barton, & L. Hirshberg, 1996) were assessed between 29 and 32 gestational weeks. The mothers' risks of distorted representations increased significantly when they had at least minor depressive symptoms. Marital distress was associated with the fathers' prenatal representations, although the association was weak; fathers within the marital distress group had less balanced representations. Coexisting marital distress and depressive symptoms were only associated with the mothers' representations; lack of marital distress and depressive symptoms increased the likelihood for mothers to have balanced representations. The results imply that marital distress and depressive symptoms are differently related to the organizations of mothers' and fathers' prenatal representations. © 2016 Michigan Association for Infant Mental Health.

    Despite media reports and educators' concerns, little substantive data have been published to document or refute the emerging reports that children prenatally exposed to cocaine have serious behavioral problems in school. Recent pilot data from this institution have indeed demonstrated teacher-reported problem behaviors following prenatal cocaine exposure after controlling for the effects of prenatal alcohol use and cigarette exposure. Imperative in the study of prenatal exposure and child outcome is an acknowledgement of the influence of other control factors such as postnatal environment, secondary exposures, and parenting issues. We report preliminary evaluation from a large ongoing historical prospective study of prenatal cocaine exposure on school-age outcomes. The primary aim of this NIDA-funded study is to determine if a relationship exists between prenatal cocaine/alcohol exposures and school behavior and, if so, to determine if the relationship is characterized by a dose-response relationship. A secondary aim evaluates the relationship between prenatal cocaine/alcohol exposures and school achievement. Both relationships will be assessed in a black, urban sample of first grade students using multivariate statistical techniques for confounding as well as mediating and moderating prenatal and postnatal variables. A third aim is to evaluate the relationship between a general standardized classroom behavioral measure and a tool designed to tap the effects thought to be specific to prenatal cocaine exposure. This interdisciplinary research team can address these aims because of the existence of a unique, prospectively collected perinatal Database, funded in part by NIAAA and NICHD. The database includes repeated measures of cocaine, alcohol, and other substances for over 3,500 births since 1986. Information from this database is combined with information from the database of one of the largest public school systems in the nation. The final sample will be

  9. The prenatal roots of music

    Full Text Available Although the idea that pulse in music may be related to human pulse is ancient and has recently been promoted by researchers (Parncutt, 2006; Snowdon & Teie, 2010, there has been no ordered delineation of the characteristics of music that are based on the sounds of the womb. I describe features of music that are based on sounds that are present in the womb: tempo of pulse (pulse is understood as the regular, underlying beat that defines the meter, amplitude contour of pulse, meter, musical notes, melodic frequency range, continuity, syllabic contour, melodic rhythm, melodic accents, phrase length, and phrase contour. There are a number of features of prenatal development that allow for the formation of long-term memories of the sounds of the womb in the areas of the brain that are responsible for emotions. Taken together, these features and the similarities between the sounds of the womb and the elemental building blocks of music allow for a postulation that the fetal acoustic environment may provide the bases for the fundamental musical elements that are found in the music of all cultures. This hypothesis is supported by a one-to-one matching of the universal features of music with the sounds of the womb: 1 all of the regularly heard sounds that are present in the fetal environment are represented in the music of every culture, and 2 all of the features of music that are present in the music of all cultures can be traced to the fetal environment.

    Triple X syndrome is a relatively common sex chromosomal abnormality occurring in 0,1% of live-born female infants. Most of these infants have a normal phenotype and only a few cases with 47, XXX karyotype have congenital malformations. We report three cases of triple X syndrome that were diagnosed prenatally by genetic amniocentesis for advanced maternal age and have been observed from birth to age of 3 to 12 years. A description of their growth and development is presented. The birth weight was normal in all patients and one of them had facial dysmorphism with right microphtalmia and auricular septal defect. During the first 2 years of life, the neuromotor development of these infants was not distinguishable from chromosomally normal children. By 3 years of age, two patients have a moderate developmental delay in speech and language. One girl 12-year-old had normal schooling. The diagnosis of the triple X syndrome can be never made because clinical demonstrations are not rather important to arouse the demand of a karyotype. Prenatal diagnosis is often made in front of the advanced maternal age. Expectant parents must be counseled as to the significance of this 47, XXX karyotype and prognostic information must be given.

  11. Prenatal diagnosis: the irresistible rise of the 'visible fetus'.

    Prenatal diagnosis was developed in the 1970s, a result of a partly contingent coming together of three medical innovations-amniocentesis, the study of human chromosomes and obstetrical ultrasound-with a social innovation, the decriminalization of abortion. Initially this diagnostic approach was proposed only to women at high risk of fetal malformations. Later, however, the supervision of the fetus was extended to all pregnant women. The latter step was strongly favoured by professionals' aspiration to prevent the birth of children with Down syndrome, an inborn condition perceived as a source of suffering for families and a burden on public purse. Experts who promoted screening for 'Down risk' assumed that the majority of women who carry a Down fetus will decide to terminate the pregnancy, and will provide a private solution to a public health problem. The generalization of screening for Down risk increased in turn the frequency of diagnoses of other, confirmed or potential fetal pathologies, and of dilemmas linked with such diagnoses. Debates on such dilemmas are usually limited to professionals. The transformation of prenatal diagnosis into a routine medical technology was, to a great extent, an invisible revolution.

  15. Medicaid reimbursement, prenatal care and infant health.

    Sonchak, Lyudmyla

    2015-12-01

    This paper evaluates the impact of state-level Medicaid reimbursement rates for obstetric care on prenatal care utilization across demographic groups. It also uses these rates as an instrumental variable to assess the importance of prenatal care on birth weight. The analysis is conducted using a unique dataset of Medicaid reimbursement rates and 2001-2010 Vital Statistics Natality data. Conditional on county fixed effects, the study finds a modest, but statistically significant positive relationship between Medicaid reimbursement rates and the number of prenatal visits obtained by pregnant women. Additionally, higher rates are associated with an increase in the probability of obtaining adequate care, as well as a reduction in the incidence of going without any prenatal care. However, the effect of an additional prenatal visit on birth weight is virtually zero for black disadvantaged mothers, while an additional visit yields a substantial increase in birth weight of over 20 g for white disadvantaged mothers.

    Congenital anomalies of the kidney and urinary tract are common findings on fetal ultrasound. The aim of this prospective observational study was to describe outcome and risk factors in 115 patients born 1995-2001. All prenatally diagnosed children were stratified into low- and high-risk group and followed postnatally clinically and by imaging at defined endpoints. Risk factors were evaluated using odds ratios. Neonatal diagnosis included pelvi-ureteric junction obstruction (n = 33), vesicoureteral reflux (n = 27), solitary mild pelvic dilatation (postnatal anteroposterior diameter 5-10 mm; n = 25), and further diagnosis as primary obstructive megaureter, unilateral multicystic dysplastic kidney, renal dysplasia and posterior urethral valves. In 38 children with prenatal isolated hydronephrosis, ultrasound normalized at median age of 1.2 years (range 0.1-9). Surgery was performed in 34 children at median age of 0.4 years (0.1-10.8). Persistent renal anomalies without surgery were present in 43 children and followed in 36 for median time of 16 years (12.2-18). Oligohydramnios and postnatal bilateral anomalies were significantly associated with surgery and impaired renal function. The majority of children had a favourable postnatal outcome, in particular children with prenatally low risk, i.e. isolated uni- or bilateral hydronephrosis. Oligohydramnios and postnatal bilateral anomalies were risk factors for non-favourable outcome. • In congenital anomalies of the kidney and urinary tract significantly poorer outcome is known in patients with bilateral renal hypoplasia or solitary kidney associated with posterior urethral valves. • Other factors as proteinuria and vesicoureteral reflux were associated with a higher risk of progression to chronic renal failure in these patients. What is New: • Unlike other studies giving us above-mentioned information, we included all patients with any kind of prenatally diagnosed congenital anomalies of the kidney

    Full Text Available Prenatal exposure to serotonin reuptake inhibitor (SRI antidepressants and maternal depression may affect prefrontal cognitive skills (executive functions; EFs including self-control, working memory and cognitive flexibility. We examined long-term effects of prenatal SRI exposure on EFs to determine whether effects are moderated by maternal mood and/or genetic variations in SLC6A4 (a gene that codes for the serotonin transporter [5-HTT] central to the regulation of synaptic serotonin levels and behavior. Children who were exposed to SRIs prenatally (SRI-exposed N=26 and non-exposed (N=38 were studied at age 6 years (M=6.3 SD=0.5 using the Hearts & Flowers task (H&F to assess EFs. Maternal mood was measured during pregnancy (3rd trimester and when the child was age 6 years (Hamilton Depression Scale. Parent reports of child behavior were also obtained (MacArthur Health & Behavior Questionnaire. Parents of prenatally SRI-exposed children reported fewer child externalizing and inattentive (ADHD behaviors. Generalized estimate equation modeling showed a significant 3-way interaction between prenatal SRI exposure, SLC6A4 variant, and maternal mood at the 6-year time-point on H&F accuracy. For prenatally SRI-exposed children, regardless of maternal mood, the H&F accuracy of children with reduced 5HTT expression (a short [S] allele remained stable. Even with increasing maternal depressive symptoms (though all below clinical threshold, EFs of children with at least one short allele were comparable to children with the same genotype whose mothers reported few if any depressive symptoms – in this sense they showed resilience. Children with two long (L alleles were more sensitive to context. When their mothers had few depressive symptoms, LL children showed extremely good EF performance – better than any other group. When their mothers reported more depressive symptoms, LL children’s EF performance was worse than that of any other group.

    To investigate whether (1) maternal psychosocial stress (depression/anxiety) during pregnancy is associated with offspring vascular function and (2) whether any association differs depending on the gestational timing of exposure to stress. We also investigated whether any association is likely to be due to intrauterine mechanisms by (3) comparing with the association of paternal stress with offspring vascular function and (4) examining whether any prenatal association is explained by maternal postnatal stress. Associations were examined in a UK birth cohort, with offspring outcomes (systolic and diastolic blood pressure, SBP and DBP, endothelial function assessed by brachial artery flow-mediated dilatation (FMD); arterial stiffness assessed by carotid to radial pulse wave velocity (PWV), brachial artery distensibility (DC), and brachial artery diameter (BD) assessed at age 10-11 years (n = 4,318). Maternal depressive symptoms and anxiety were assessed at 18 and 32 weeks gestation and 8 months postnatally. Paternal symptoms were assessed at week 19. With the exception of DBP and BD, there were no associations of maternal depressive symptoms with any of the vascular outcomes. Maternal depressive and anxiety symptoms were associated with lower offspring DBP and wider BD, though the latter attenuated to the null with adjustment for confounding factors. Paternal symptoms were not associated with offspring outcomes. Maternal postnatal depressive symptoms were associated with lower offspring SBP. We found no evidence to support the hypothesis that maternal stress during pregnancy adversely affects offspring vascular function at age 10-12 years via intrauterine mechanisms. © Authors 2013 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    Full Text Available BACKGROUND: The etiology of type-2 diabetes is only partly known, and a possible role of prenatal stress in programming offspring for insulin resistance has been suggested by animal models. Previously, we found an association between prenatal stress and type-1 diabetes. Here we examine the association between prenatal exposure to maternal bereavement during preconception and pregnancy and development of type-2 diabetes in the off-spring. METHODS: We utilized data from the Danish Civil Registration System to identify singleton births in Denmark born January 1(st 1979 through December 31(st 2008 (N = 1,878,246, and linked them to their parents, grandparents, and siblings. We categorized children as exposed to bereavement during prenatal life if their mothers lost an elder child, husband or parent during the period from one year before conception to the child's birth. We identified 45,302 children exposed to maternal bereavement; the remaining children were included in the unexposed cohort. The outcome of interest was diagnosis of type-2 diabetes. We estimated incidence rate ratios (IRRs from birth using log-linear poisson regression models and used person-years as the offset variable. All models were adjusted for maternal residence, income, education, marital status, sibling order, calendar year, sex, and parents' history of diabetes at the time of pregnancy. RESULTS: We found children exposed to bereavement during their prenatal life were more likely to have a type-2 diabetes diagnosis later in life (aIRR: 1.31, 1.01-1.69. These findings were most pronounced when bereavement was caused by death of an elder child (aIRR: 1.51, 0.94-2.44. Results also indicated the second trimester of pregnancy to be the most sensitive period of bereavement exposure (aIRR:2.08, 1.15-3.76. CONCLUSIONS: Our data suggests that fetal exposure to maternal bereavement during preconception and the prenatal period may increase the risk for developing type-2 diabetes in

    This study was designed to evaluate the impact of an interactive computer program developed to empower prenatal communication among women with restricted literacy skills. A total of 83 women seeing 17 clinicians were randomized to a computer-based communication activation intervention (Healthy Babies Healthy Moms [HBHM]) or prenatal education (Baby Basics [BB]) prior to their prenatal visit. Visit communication was coded with the Roter Interaction Analysis System, and postvisit satisfaction was reported. Participants were on average 24 years of age and 25 weeks pregnant; 80% were African American. Two thirds scored ≤8th grade on a literacy screener. Women with literacy deficits were more verbally active, disclosed more medical and psychosocial/lifestyle information, and were rated as more dominant by coders in the HBHM group relative to their counterparts in the BB group (all ps literacy in the HBHM relative to the BB group (p literacy deficits. Satisfaction, however, tended to be lower for these women.

    Full Text Available Abstracts: Congenital paraesophageal hiatal hernia (CPEH is a rare condition. CPEH can cause important clinical problems such as gastric volvulus, hematemesis, vomiting, failure to thrive, and respiratory distress, it requires early diagnosis and prompt surgical treatment. In this paper, we describe a case of CPEH that was suspected in a prenatal ultrasound. Postnatal upper gastrointestinal contrast series confirmed a CPEH with intrathoracic gastric volvulus. An emergency operation was performed. The stomach was reduced, the hiatal defect was repaired by crural approximation, and a Nissen fundoplication was done. The prenatal diagnosis of CPEH is unusual, but prenatal detection is important because it allows planned neonatal surgery before the onset of complications and reduces long-term morbidity.

    Emerging work has examined neurodevelopmental outcomes following prenatal exposure to per- and polyfluoroalkyl substances (PFAS), but few studies have assessed associations with autism spectrum disorder (ASD). Our objective was to estimate associations of maternal prenatal PFAS concentrations with ASD and intellectual disability (ID) in children. Participants were from a population-based nested case-control study of children born from 2000 to 2003 in southern California, including children diagnosed with ASD ( n =553), ID without autism ( n =189), and general population (GP) controls ( n =433). Concentrations of eight PFAS from stored maternal sera collected at 15-19 wk gestational age were quantified and compared among study groups. We used logistic regression to obtain adjusted odds ratios for the association between prenatal PFAS concentrations (parameterized continuously and as quartiles) and ASD versus GP controls, and separately for ID versus GP controls. Geometric mean concentrations of most PFAS were lower in ASD and ID groups relative to GP controls. ASD was not significantly associated with prenatal concentrations of most PFAS, though significant inverse associations were found for perfluorooctanoate (PFOA) and perfluorooctane sulfonate (PFOS) [adjusted ORs for the highest vs. lowest quartiles 0.62 (95% CI: 0.41, 0.93) and 0.64 (95% CI: 0.43, 0.97), respectively]. Results for ID were similar. Results from this large case-control study with prospectively collected prenatal measurements do not support the hypothesis that prenatal exposure to PFAS is positively associated with ASD or ID. https://doi.org/10.1289/EHP1830.

    The role of mother-infant interaction quality is studied in the relation between prenatal maternal emotional symptoms and child behavioral problems. Healthy pregnant, Dutch women (N = 96, M = 31.6, SD = 3.3) were allocated to the "exposed group" (n = 46), consisting of mothers with high levels of prenatal feelings of anxiety and depression, or the "low-exposed group" (n = 50), consisting of mothers with normal levels of depressive or anxious symptoms during pregnancy. When the children (49 girls, 47 boys) were 23 to 60 months of age (M = 39.0, SD = 9.6), parents completed the Child Behavior Checklist (T.M. Achenbach & L.A. Rescorla, ), and mother-child interaction quality during a home visit was rated using the Emotional Availability Scales. There were no differences in mother-child interaction quality between the prenatally exposed and low-exposed groups. Girls exposed to high prenatal emotional symptoms showed more internalizing problems, if maternal interaction quality was less optimal. No significant effects were found for boys. © 2017 Michigan Association for Infant Mental Health.

    Poor executive functioning has been implicated in children's concurrent and future behavioral difficulties, making work aimed at understanding processes related to the development of early executive function (EF) critical for models of developmental psychopathology. Deficits in EF have been associated with adverse prenatal experiences, genetic influences, and temperament characteristics. However, our ability to disentangle the predictive and independent effects of these influences has been limited by a dearth of genetically informed research designs that also consider prenatal influences. The present study examined EF and language development in a sample of 361 toddlers who were adopted at birth and reared in nonrelative adoptive families. Predictors included genetic influences (as inherited from birth mothers), prenatal risk, and growth in child negative emotionality. Structural equation modeling indicated that the effect of prenatal risk on toddler effortful attention at age 27 months became nonsignificant once genetic influences were considered in the model. In addition, genetic influences had unique effects on toddler effortful attention. Latent growth modeling indicated that increases in toddler negative emotionality from 9 to 27 months were associated with poorer delay of gratification and poorer language development. Similar results were obtained in models incorporating birth father data. Mechanisms of intergenerational transmission of EF deficits are discussed.

    The "Unborn Child" (UC) option provides state Medicaid/Children's Health Insurance Program (CHIP) programs with a new strategy to extend prenatal coverage to low-income women who would otherwise have difficulty enrolling in or would be ineligible for Medicaid. To examine the association of the UC option with the probability of enrollment in Medicaid/CHIP during pregnancy and probability of receiving adequate prenatal care. We use pooled cross-sectional data from the Pregnancy Risk Assessment Monitoring System from 32 states between 2004 and 2010 (n = 81,983). Multivariable regression is employed to examine the association of the UC option with Medicaid/CHIP enrollment during pregnancy among eligible women who were uninsured preconception (n = 45,082) and those who had insurance (but not Medicaid) preconception (n = 36,901). Multivariable regression is also employed to assess the association between the UC option and receipt of adequate prenatal care, measured by the Adequacy of Prenatal Care Utilization Index. Residing in a state with the UC option is associated with a greater probability of Medicaid enrollment during pregnancy relative to residing in a state without the policy both among women uninsured preconception (88% vs. 77%, P option is not significantly associated with receiving adequate prenatal care, among both women with and without insurance preconception. The UC option provides states a key way to expand or simplify prenatal insurance coverage, but further policy efforts are needed to ensure that coverage improves access to high-quality prenatal care.

    Illegal drug use throughout the nation is a problem of epidemic proportion. Of particular concern is drug use among pregnant women. In most cases, these women have little hope of achieving a better life for themselves or their children. Illegal drugs, cocaine in particular, can have devastating effects on the neonate. These effects can last well into childhood and can exhibit themselves in academic, social, and family situations. Challenges for the neonatal nurse include early identification of these infants and use of available resources. This article addresses prenatal cocaine use and support services for drug-dependent women, effects of cocaine during the neonatal period, possible neonatal and infant outcomes, and implications for nursing practice.

    The American Journal of Medical Genetics Part A is to be congratulated for taking a leadership role by publishing a number of papers challenging the status quo of prenatal counseling for Down syndrome and of care for children and adults with Down syndrome. Parents want to know about the future abilities and potential of their fetus with Down syndrome, not simply negative medical information that may be outdated. Those providing counseling and those providing medical care could benefit from contact with individuals with Down syndrome outside the medical context. It is imperative that each person with Down syndrome be viewed as a unique individual with particular talents. Medical care providers should work with parents to help the child or adult with Down syndrome reach his/her goals. Copyright © 2012 Wiley Periodicals, Inc.

    A variety of neoplasms can develop in each tetal organ. Most fetal neoplasms can be detected by careful prenatal ultrasonographic examination. Some neoplosms show specific ultrasonographic findings suggesting the differential diagnosis, but others do not. Knowledge of the presence of a neoplasm in the fetus may alter the prenatal management of a pregnancy and the mode of delivery, and facilitates immediate postnatal treatment. During the last five years, we experienced 32 cases of fetal neoplasms in a variety of organs. We describe their typical and ultrasonographic findings with correlating postnatal CT, MRI, and pathologic findings

    Intestinal volvulus is a life-threatening emergency requiring prompt surgical management. Prenatal intestinal volvulus is rare, and most are secondary to intestinal atresia, mesenteric defect or without any underlying cause. Cystic fibrosis (CF) is known to cause digestive tract disorders. After birth, 10-15% of newborns with CF may develop intestinal obstruction within a few days of birth because of meconial ileus. 1 This obstruction is a result of dehydrated thickened meconium obstructing the intestinal lumen. We report two cases of fetuses with prenatal diagnosis of segmental volvulus in whom CF was diagnosed. 2016 BMJ Publishing Group Ltd.

    Phthalate diesters are commonly used and have been well established as environmental endocrine disruptors. However, few studies have examined their effects on sex steroid hormones in children. We followed children over time to examine the association between pre- and post-natal phthalate exposure and sex steroid hormone levels at 2, 5, 8, and 11 years of age. We recruited 430 pregnant women from central Taiwan from 2000 to 2001 and assessed their children at birth, 2, 5, 8, and 11 years of age. We studies children with at least one measurement for both phthalate and hormone levels during each any of the follow-up time point (n = 193). Estradiol, free testosterone, testosterone, and progesterone were measured from venous blood. Three monoesters of di-2-ethylhexyl phthalate (DEHP), mono-benzyl phthalate, mono-n-butyl phthalate, mono-ethyl phthalate, and mono-methyl phthalate were measured in maternal urine collected during the 3rd trimester and child urine collected at each follow-up point. The sum of mono-2-ethylhexyl phthalate (∑MEHP) was calculated by summing the concentrations of the three DEHP monoesters. Generalized estimating equation regression analysis with repeated measures was used to estimate associations between phthalate metabolites and hormone levels. After adjustment for potential confounders, maternal ∑MEHP level was associated with decreased levels of progesterone in girls (β = -0.309 p = 0.001). The child ∑MEHP concentration was associated with decreased levels of progesterone for girls (β = -0.194, p = 0.003) and with decreased levels of free testosterone for boys (β = -0.124, p = 0.004). Early-life DEHP exposure may alter sex steroid hormones of children over time, which may pose potential reproductive health risks. Copyright © 2017 The Authors.

    To evaluate the performance of different antenatal tools for the monitoring of fetuses with isolated intrauterine growth restriction (IUGR). To define the prenatal management of IUGR and indications for delivery before and after 32 weeks of gestation. PubMed, Embase and the Cochrane databases were searched using the keywords "IUGR", "fetal growth restriction", "cardiotocography", "amniotic fluid", "ultrasound assessment", "biophysical profile", "Doppler ultrasonography", "randomized trial", "meta-analysis". These terms were also combined together. Fetal monitoring of isolated IUGR should be based on the combined use of fetal heart rate (FHR) and ultrasound Doppler. The use of computerized FHR, with short-term variability (STV) measurement allows longitudinal monitoring and provides objective values upon which to decide very premature delivery (LE3). The use of umbilical Doppler is associated with a decrease in perinatal morbidity, especially in IUGR (LE1). It should be the first-line mean for the monitoring of SGA and IUGR fetuses (LE1). The additional use of cerebral Doppler is associated with a better predictive value for a poor perinatal outcome than the umbilical Doppler alone (LE3). Therefore, cerebral Doppler should be used in fetuses with IUGR, whether the umbilical Doppler is normal or not. As morbidity and mortality is increased in IUGR with pathological ductus venosus, the use of this Doppler should be considered in the monitoring of IUGR at before 32 weeks (professional consensus). Routine hospitalization is not mandatory for the monitoring of fetuses with IUGR/SGA. However, tertiary referral is advisable in cases of severe IUGR at between 26 to 32 weeks (professional consensus). The decision for delivery cannot be standardized and should be based on the combined analysis of gestational age, fetal heart rate analysis and Doppler study (professional consensus). Monitoring of fetuses with IUGR and decision for delivery should be based on the combined

    Full Text Available BACKGROUND: To assess the risk of developing Type-1 diabetes among children who were exposed to maternal bereavement during the prenatal or 1-year preconception period. METHODS: We identified N = 1,548,746 singleton births born in Denmark between January 1(st 1979 through December 31(st 2004, and their next of kin. Altogether, 39,857 children were exposed to bereavement during their prenatal life. The main outcome of interest was hospitalization for type-1 diabetes (ICD 8: 249; ICD 10: E10. RESULTS: We found the strongest association for type-1 diabetes among children exposed to traumatic father or sibling deaths (aIRR: 2.03, 1.22-3.38; the association was mainly seen for girls (aIRR: 2.91, 1.61-5.26. CONCLUSIONS: We found evidence to suggest that female fetuses exposed to severe prenatal stress are at increased risk for developing type-1 diabetes.

    To investigate the effects of mothers' prenatal depression on parenting during infancy, ensuing childhood regulation, and body mass index (BMI) at age 3 years. The sample (N = 284) included teen mothers (n = 157), adult mothers with low education (n = 69), and adult mothers with high education (n = 58), and their first-born children. Maternal depressive symptoms were assessed prenatally through self-report; observational methods and self-report were used to assess mothers' parenting at 4, 6, and 8 months and children's regulation at 18, 24, and 30 months of age. Child BMI was measured at 36 months of age in the laboratory. Structural equation modeling supported mediating processes such that mothers who reported more depressive symptoms prenatally exhibited less positive parenting during infancy. In turn, less positive parenting predicted lower levels of child regulation during toddlerhood, which predicted higher child BMIs at 36 months of age, even after controlling for infant birth weight and concurrent maternal BMI. Models comparing groups (teen mothers, adult low-educated mothers, and adult-high educated mothers) indicated mean differences in maternal depression, parenting, and child regulation, but similar patterns of prediction across groups. The present study provides evidence of cascading psychosocial processes beginning prenatally and continuing through infancy, toddlerhood, and into early childhood. Results have implications for family-wide intervention strategies to help lower the risk for early onset obesity in children. Copyright © 2016 Elsevier Inc. All rights reserved.

    We examined associations of depressive symptoms and social support with late and inadequate prenatal care in a low-income urban population. The sample was prenatal care patients at five community health centers. Measures of depressive symptoms, social support, and covariates were collected at prenatal care entry. Prenatal care entry and adequacy came from birth certificates. We examined outcomes of late prenatal care and less than adequate care in multivariable models. Among 2341 study participants, 16% had elevated depressive symptoms, 70% had moderate/poor social support, 21% had no/low partner support, 37% had late prenatal care, and 29% had less than adequate prenatal care. Women with both no/low partner support and elevated depressive symptoms were at highest risk of late care (AOR 1.85, CI 1.31, 2.60, p care (AOR 0.74, CI 0.54, 1.10, p = 0.051). Women with moderate/high depressive symptoms were less likely to experience less than adequate care compared to women with low symptoms (AOR 0.73, CI 0.56, 0.96, p = 0.022). Social support and partner support were negatively associated with indices of prenatal care use. Partner support was identified as protective for women with depressive symptoms with regard to late care. Study findings support public health initiatives focused on promoting models of care that address preconception and reproductive life planning. Practice-based implications include possible screening for social support and depression in preconception contexts.

    Noninvasive prenatal diagnosis for single gene disorders is coming to fruition in its clinical utility. The presence of cell-free DNA in maternal plasma has been recognized for many years, and a number of applications have developed from this. Noninvasive prenatal diagnosis for single gene disorders has lagged behind due to complexities of technology development, lack of investment and the need for validation samples for rare disorders. Publications are emerging demonstrating a variety of technical approaches and feasibility of clinical application. Techniques for analysis of cell-free DNA including digital PCR, next-generation sequencing and relative haplotype dosage have been used most often for assay development. Analysis of circulating fetal cells in the maternal blood is still being investigated as a viable alternative and more recently transcervical trophoblast cells. Studies exploring ethical and social issues are generally positive but raise concerns around the routinization of prenatal testing. Further work is necessary to make testing available to all patients with a pregnancy at risk of a single gene disorder, and it remains to be seen if the development of more powerful technologies such as isolation and analysis of single cells will shift the emphasis of noninvasive prenatal diagnosis. As testing becomes possible for a wider range of conditions, more ethical questions will become relevant.

    2006-10-01

    The pressing need for empirically informed public policies aimed at understanding and promoting children's health has challenged environmental scientists to modify traditional research paradigms and reevaluate their roles and obligations toward research participants. Methodologic approaches to children's environmental health research raise ethical challenges for which federal regulations may provide insufficient guidance. In this article I begin with a general discussion of privacy concerns and informed consent within pediatric environmental health research contexts. I then turn to specific ethical challenges associated with research on genetic determinants of environmental risk, prenatal studies and maternal privacy, and data causing inflicted insight or affecting the informational rights of third parties.

    Methyl mercury (MeHg) is a well-known neurotoxin and evidence suggests that also low level exposure may affect prenatal neurodevelopment. Uncertainty exists as to whether the maternal MeHg burden in Norway might affect child neurodevelopment. To evaluate the association between prenatal mercury exposure, maternal seafood consumption and child language and communication skills at age five. The study sample comprised 38,581 mother-child pairs in the Norwegian Mother and Child Cohort Study. Maternal mercury blood concentration in gestational week 17 was analysed in a sub-sample of 2239 women. Prenatal mercury exposure from maternal diet was calculated from a validated FFQ answered in mid-pregnancy. Mothers reported children's language and communications skills at age five by a questionnaire including questions from the Ages and Stages Questionnaire (ASQ), the Speech and Language Assessment Scale (SLAS) and the Twenty Statements about Language-Related Difficulties (language 20). We performed linear regression analyses adjusting for maternal characteristics, nutritional status and socioeconomic factors. Median maternal blood mercury concentration was 1.03μg/L, dietary mercury exposure was 0.15μg/kgbw/wk, and seafood intake was 217g/wk. Blood mercury concentrations were not associated with any language and communication scales. Increased dietary mercury exposure was significantly associated with improved SLAS scores when mothers had a seafood intake below 400g/wk in the adjusted analysis. Sibling matched analysis showed a small significant adverse association between those above the 90th percentile dietary mercury exposure and the SLAS scores. Maternal seafood intake during pregnancy was positively associated with the language and communication scales. Low levels of prenatal mercury exposure were positively associated with language and communication skills at five years. However, the matched sibling analyses suggested an adverse association between mercury and child

    Primary infection of Toxoplasma gondii during pregnancy can be transmitted to the unborn child and may have serious consequences, including retinochoroiditis, hydrocephaly, cerebral calcifications, encephalitis, splenomegaly, hearing loss, blindness, and death. Austria, a country with moderate seroprevalence, instituted mandatory prenatal screening for toxoplasma infection to minimize the effects of congenital transmission. This work compares the societal costs of congenital toxoplasmosis under the Austrian national prenatal screening program with the societal costs that would have occurred in a No-Screening scenario. We retrospectively investigated data from the Austrian Toxoplasmosis Register for birth cohorts from 1992 to 2008, including pediatric long-term follow-up until May 2013. We constructed a decision-analytic model to compare lifetime societal costs of prenatal screening with lifetime societal costs estimated in a No-Screening scenario. We included costs of treatment, lifetime care, accommodation of injuries, loss of life, and lost earnings that would have occurred in a No-Screening scenario and compared them with the actual costs of screening, treatment, lifetime care, accommodation, loss of life, and lost earnings. We replicated that analysis excluding loss of life and lost earnings to estimate the budgetary impact alone. Our model calculated total lifetime costs of €103 per birth under prenatal screening as carried out in Austria, saving €323 per birth compared with No-Screening. Without screening and treatment, lifetime societal costs for all affected children would have been €35 million per year; the implementation costs of the Austrian program are less than €2 million per year. Calculating only the budgetary impact, the national program was still cost-saving by more than €15 million per year and saved €258 million in 17 years. Cost savings under a national program of prenatal screening for toxoplasma infection and treatment are

    We report 6 cases of polysplenic syndrome diagnosed on prenatal sonography. The mean menstrual age at the time of presentation was 275 weeks (range 184 to 38 weeks). All cases were examined using level-II prenatal sonography. The sonographic findings of polysplenic syndrome were retrograde analyzed and compared to the autopsy or postnatal findings. Polysplenia was detected in 5 cases on the prenatal sonography. Associated cardiovascular anomalies were detected in all 6 cases, all of which had more than one anomaly, namely complete atrioventricular septal defect in two cases, double outlet right ventricle combined with rudimentary LV or mitral atresia in two cases and VSD and ASD in one case each. There were three cases of interrupted IVC with azygous continuation of the posterior thorax. Bradycardia was observed in 2 cases, one of which showed AV dissociation of rhythm. Visceral abnormalities were present in all cases and there were combined anomalies such as echogenic bowel, pelviectasia, horseshoe kidney, and posterior neck cystic hygroma and fetal hydrops. Four cases terminated pregnancy. The autopsy results of 2 cases were comparable to those of the prenatal sonography, however autopsies were not performed in 2 cases. One fetus near term was delivered and the baby subsequently underwent heart surgery and was still alive at the last follow-up. The remaining one case was lost to follow-up. If multiple fetal anomalies, including complex heart disease and polysplenia, are detected in the prenatal sonography, a diagnosis of polysplenic syndrome can be made. IVC interruption with azygous continuation can also be helpful in the diagnosis of polysplenic syndrome, and this can be observed by detecting the double vessel of the posterior thorax

    Prenatal distress has been linked to pregnancy complications and poor offspring's health, despite the fact that longitudinal assessments of various stress dimensions are still lacking. Hence, we aimed to assess perceived stress over the course of pregnancy. Moreover, we examined whether social support and coping styles are linked to prenatal stress trajectories. Data from 543 women participating in the PRINCE (Prenatal Identification of Children Health) study, a prospective population-based cohort study, was used for the present analyses. Once per trimester the women completed questionnaires regarding different psychometric measures, including the Perceived Stress Scale (PSS). Linear mixed regression models were used to examine perceived stress development longitudinally and to relate social support and coping styles to stress trajectories during pregnancy. A significant decrease of perceived stress was observed over the course of pregnancy. Stratifying the study sample according to parity, women delivering their first child had continuously lower perceived stress scores compared to women having already one or more children, and a significant decrease during pregnancy was exclusively observed in primiparous women. Both, positive coping strategies and higher perceived and received social support were independently associated with lower perceived stress, while evasive coping strategies were associated with higher levels of perceived stress. Our study reveals stress perception trajectories during pregnancies in primi- and multiparous women. Our findings underscore the need for intervention strategies aiming to improve social support and positive coping strategies especially in multiparous women in order to reduce the risks for adverse pregnancy outcomes.

    A cohort of 154 children born between April 26, 1986 and February 26, 1987 to mothers who had been evacuated from Pripyat to Kiev, and 143 classmates from Kiev were examined. Individual dose reconstruction of the children exposed in utero was carried out considering internal and external exposure. Prenatal equivalent brain doses were 19.2 ± 11.3 mSv and 0.8 ± 0.2 mSv for the exposed and control groups, respectively. Thyroid doses in utero were 760.4 ± 631.8.1 mSv and 44.5 ± 43.3 mSv for the exposed and control groups, correspondingly. There were 20 children from Pripyat town (13.2%) who had been exposed in utero to thyroid doses >1 Sv. The prenatally exposed children show significantly more diseases of the nervous system and mental disorders. Among mothers of the exposed group of children with the neuropsychiatric disorders there are much more depression and somatization, as well as mental disorders

    We assessed the screening and remediation of home lead hazards prenatally in a high-risk population, hypothesizing that average blood-lead level and the number of poisonings would drop by 25%. One hundred fifty-two women underwent prenatal home inspections by certified lead inspectors. The hazards that were identified were remediated. The blood-lead levels of children of participating women were compared with matched control subjects. Blood-lead levels were obtained from 60 children and compared with matched control subjects. The average blood-lead level of children in the treatment group was 2.70 μg/dL vs 3.73 μg/dL in control subjects (P = .019). The percentage of children with levels >10 μg/dL in the treatment group was 0% vs 4.2% in control subjects (P = .128). Screening and remediation of houses of pregnant women is effective to reduce the average blood-lead level and number of children that exceed the federal level of concern for lead poisoning in a high-risk population.

Longitudinal follow-up study. Denmark, 2003-2008. A total of 1780 women and their children sampled from the Danish National Birth Cohort. Self-reported information on use of SSRI and anxiolytics was obtained from the Danish National Birth Cohort at the time of consent and from two prenatal interviews. Intelligence was assessed at age 5 years, and parental education, maternal intelligence quotient (IQ), maternal smoking and alcohol consumption in pregnancy, the child's age at testing, sex, and tester were included in the full model. The IQ of 13 medication-exposed children was compared with the IQ of 19 children whose mothers had untreated depression and 1748 control children. Wechsler Preschool and Primary Scale of Intelligence - Revised. In unadjusted analyses, children of mothers who used antidepressants or anxiolytics during pregnancy had higher verbal IQ; this association, however, was insignificant after adjustment for potentially confounding maternal and child factors. No consistent associations between IQ and fetal exposure to antidepressants and anxiolytics were observed, but the study had low statistical power, and there is an obvious need to conduct long-term follow-up studies with comprehensive cognitive assessment and sufficiently large samples of adolescent or adult offspring. © 2015 Nordic Federation of Societies of Obstetrics and Gynecology.

    Full Text Available Prenatal exposure to valproic acid (VPA, an established antiepileptic drug, has been reported to impair postnatal cognitive function in children born to VPA-treated epileptic mothers. However, how these defects arise and how they can be overcome remain unknown. Using mice, we found that comparable postnatal cognitive functional impairment is very likely correlated to the untimely enhancement of embryonic neurogenesis, which led to depletion of the neural precursor cell pool and consequently a decreased level of adult neurogenesis in the hippocampus. Moreover, hippocampal neurons in the offspring of VPA-treated mice showed abnormal morphology and activity. Surprisingly, these impairments could be ameliorated by voluntary running. Our study suggests that although prenatal exposure to antiepileptic drugs such as VPA may have detrimental effects that persist until adulthood, these effects may be offset by a simple physical activity such as running.

    Background: Few studies have examined whether prenatal exposure to perfluoroalkyl substances (PFASs) is associated with childhood adiposity. Objective: We examined associations of prenatal exposure to PFASs with adiposity in early and mid-childhood. Methods: We measured plasma PFAS concentrations in 1,645 pregnant women (median, 9.6 weeks gestation) enrolled in Project Viva, a prospective pre-birth cohort study in Massachusetts (USA), between 1999 and 2002. We assessed overall and central adiposity in 1,006 children in early childhood (median, 3.2 years) and 876 in mid-childhood (median, 7.7 years) using anthropometric and dual X-ray absorptiometry (DXA) measurements. We fitted multivariable linear regression models to estimate exposure-outcome associations and evaluated effect modification by child sex. Results: Median (25–75th percentiles) prenatal plasma perfluorooctanoate (PFOA), perfluorooctane sulfonate (PFOS), perfluorohexane sulfonate (PFHxS), and perfluorononanoate (PFNA) concentrations in children assessed in early childhood were 5.6 (4.1–7.7), 24.8 (18.4–33.9), 2.4 (1.6–3.8), and 0.6 (0.5–0.9) ng/mL, respectively. Among girls, each interquartile range increment of prenatal PFOA concentrations was associated with 0.21 kg/m2 (95% CI: –0.05, 0.48) higher body mass index, 0.76 mm (95% CI: –0.17, 1.70) higher sum of subscapular and triceps skinfold thickness, and 0.17 kg/m2 (95% CI: –0.02, 0.36) higher DXA total fat mass index in mid-childhood. Similar associations were observed for PFOS, PFHxS, and PFNA. We observed null associations for boys and early-childhood adiposity measures. Conclusions: In this cohort, prenatal exposure to PFASs was associated with small increases in adiposity measurements in mid-childhood, but only among girls.

    The enlargement of suprarenal gland is related to preterm birth and the birth weight. The ultrasound measurement of fetal adrenal gland volume may identify women at risk for impending preterm birth. The aim of our study was to investigate the newborns in the region of western Slovakia followed up due to suprarenal gland enlargement. To set the ratio of prenatally diagnosed suprarenal gland enlargment, postnatal managment and treatment and interventions. The newborns with congenital adrenal hyperplasia were excluded. We have analyzed 6 years of medical records of all cases from the western Slovakia region of suprarenal gland enlargement encountered to 1st Pediatric Department, Children's University Hospital Bratislava Republic in the time period of January 2010 to Janurary 2016. The diagnosis of suprarenal gland enlargement was set by ultrasound examination performed on the 4th postnatal day as an overall screening test. Newborns with positive laboratory screening on congenital adrenal hyperplasia (CAH) were excluded from our study. We analyzed the origin of surarenal gland enlargement, gestation week on the due date, the birth weight and other comorbidities and genetic pathologies in newborns with the enlarged suprarenal glands. There were 6 newborns followed up due to suprarenal gland enlargement. All of the patients had diagnosed the adrenal haemorrhage. Adrenal lesions like adrenal cysts or neuroblastomas were not confirmed. All of the adrenal enlargements were benign with no need of other medical or surgical intervention. None of the newborn patients had other genetic abnormalities, mineral or hormonal imbalances, problems with arterial pressure or haemodynamic instability. All of the patients underwent at least 5 prenatal ultrasound tests and at least 2 postnatal ultrasound measurements. The avarage birth weight was 3030 grams (2700 grams - to 3750 grams). The avarage birth lenght was 50 cm (47 centimeter to 53 cm).The average gestation week (gw) on due date

    Background: Phthalates are used as plasticizers in soft polyvinyl chloride (PVC) and in a large number of consumer products. Because of reported health risks, diisononyl phthalate (DiNP) has been introduced as a replacement for di(2-ethylhexyl) phthalate (DEHP) in soft PVC. This raises concerns because animal data suggest that DiNP may have antiandrogenic properties similar to those of DEHP. The anogenital distance (AGD)—the distance from the anus to the genitals—has been used to assess reproductive toxicity. Objective: The objective of this study was to examine the associations between prenatal phthalate exposure and AGD in Swedish infants. Methods: AGD was measured in 196 boys at 21 months of age, and first-trimester urine was analyzed for 10 phthalate metabolites of DEP (diethyl phthalate), DBP (dibutyl phthalate), DEHP, BBzP (benzylbutyl phthalate), as well as DiNP and creatinine. Data on covariates were collected by questionnaires. Results: The most significant associations were found between the shorter of two AGD measures (anoscrotal distance; AGDas) and DiNP metabolites and strongest for oh-MMeOP [mono-(4-methyl-7-hydroxyloctyl) phthalate] and oxo-MMeOP [mono-(2-ethyl-5-oxohexyl) phthalate]. However, the AGDas reduction was small (4%) in relation to more than an interquartile range increase in DiNP exposure. Conclusions: These findings call into question the safety of substituting DiNP for DEHP in soft PVC, particularly because a shorter male AGD has been shown to relate to male genital birth defects in children and impaired reproductive function in adult males and the fact that human levels of DiNP are increasing globally.

    2010-08-01

    Full Text Available Abstract Background Polychlorinated biphenyls (PCBs are ubiquitous environmental toxins. Although there is growing evidence to support an association between PCBs and deficits of neurodevelopment, the specific mechanisms are not well understood. The potentially different roles of specific PCB groups defined by chemical structures or hormonal activities e.g., dioxin-like, non-dioxin like, or anti-estrogenic PCBs, remain unclear. Our objective was to examine the association between prenatal exposure to defined subsets of PCBs and neurodevelopment in a cohort of infants in eastern Slovakia enrolled at birth in 2002-2004. Methods Maternal and cord serum samples were collected at delivery, and analyzed for PCBs using high-resolution gas chromatography. The Bayley Scales of Infant Development -II (BSID were administered at 16 months of age to over 750 children who also had prenatal PCB measurements. Results Based on final multivariate-adjusted linear regression model, maternal mono-ortho-substituted PCBs were significantly associated with lower scores on both the psychomotor (PDI and mental development indices (MDI. Also a significant association between cord mono-ortho-substituted PCBs and reduced PDI was observed, but the association with MDI was marginal (p = 0.05. Anti-estrogenic and di-ortho-substituted PCBs did not show any statistically significant association with cognitive scores, but a suggestive association between di-ortho-substituted PCBs measured in cord serum and poorer PDI was observed. Conclusion Children with higher prenatal mono-ortho-substituted PCB exposures performed more poorly on the Bayley Scales. Evidence from this and other studies suggests that prenatal dioxin-like PCB exposure, including mono-ortho congeners, may interfere with brain development in utero. Non-dioxin-like di-ortho-substituted PCBs require further investigation.

    Full Text Available In recent years, prenatal diagnosis and elective pregnancy termination have affected the reported birth prevalence of trisomies. Trisomy 13, or Patau syndrome, represents the third autosomic trisomy in order of frequency, after trisomy 21 (Down syndrome and trisomy 18 (Edwards syndrome, with a prevalence at birth estimated as between 1:12000 and 1:29000. In this study, we are presenting the results of cytogenetic analysis and clinic assessment in fetus of a woman at 22 weeks gestation, who were referred to our genetic diagnostic laboratory with abnormal triple test result, omphalosel and hydrocephaly. We performed the cordocentesis and pedigree analysis. We found a karyotype (47,XY,+13 in fetus. Because individuals of the family didn’t want, we were not followed the pregnancy prognosis for the mother and the fetus. We were recommending to the prenatal diagnosis for their further pregnancies.

    A healthy 27-year-old pregnant woman underwent sonographic examination because her uterine size was large for 20 weeks' menstrual age. Sonograms showed short fetal limbs with hitchhiker thumbs and toes, thoracic scoliosis, clubbed feet, and polyhydramnios. The ossification of all bony structures appeared normal, and there was no evidence of fractures. On the basis of these sonographic findings, we diagnosed skeletal dysplasia and short-limbed dwarfism, most likely diastrophic dwarfism. We counseled the parents, and the pregnancy was continued. At 37 weeks menstrual age, the patient vaginally delivered a male infant that weighed 2,560 g. The infant survived with respiratory support during his first few days of life. Postnatal physical and radiologic examinations confirmed the prenatal diagnosis of diastrophic dwarfism. Sonography is the modality of choice for prenatal detection of diastrophic dwarfism.

    2016-03-01

    Despite efforts to improve access to prenatal care, emerging adult Latinas in the United States continue to enter care late in their pregnancies and/or underutilize these services. Since little is known about emerging adult Latinas and their prenatal care experiences, the purpose of this study was to identify actual and perceived prenatal care barriers in a sample of 54 emerging adult Latinas between 18 and 21 years of age. More than 95% of the sample experienced personal and institutional barriers when attempting to access prenatal care. Results from this study lend support for policy changes for time away from school or work to attend prenatal care and for group prenatal care. © 2016. All rights reserved.

    Full Text Available Objective: To identify prenatal, perinatal and postnatal risk factors in children with autism spectrum disorder (ASD by comparing them to their siblings without autistic disorders. Method: The present study is cross sectional and comparative. It was conducted over a period of three months (July–September 2014. It included 101 children: 50 ASD's children diagnosed according to DSM-5 criteria and 51 unaffected siblings. The severity of ASD was assessed by the CARS. Results: Our study revealed a higher prevalence of prenatal, perinatal and postnatal factors in children with ASD in comparison with unaffected siblings. It showed also a significant association between perinatal and postnatal factors and ASD (respectively p = 0.03 and p = 0.042. In this group, perinatal factors were mainly as type of suffering acute fetal (26% of cases, long duration of delivery and prematurity (18% of cases for each factor, while postnatal factors were represented principally by respiratory infections (24%. As for parental factors, no correlation was found between advanced age of parents at the moment of the conception and ASD. Likewise, no correlation was observed between the severity of ASD and different factors. After logistic regression, the risk factors retained for autism in the final model were: male gender, prenatal urinary tract infection, acute fetal distress, difficult labor and respiratory infection. Conclusions: The present survey confirms the high prevalence of prenatal, perinatal and postnatal factors in children with ASD and suggests the intervention of some of these factors (acute fetal distress and difficult labor, among others, as determinant variables for the genesis of ASD.

    Mothers have many opportunities to invest in their own or their child's health and well-being during pregnancy and immediately after birth. These investments include seeking prenatal care, taking prenatal vitamins, and breastfeeding. In this paper, we investigate a potential determinant of mothers' investments that has been largely overlooked by previous research-birth order. Data are from the National Longitudinal Study of Youth 1979 (NLSY79) Child and Young Adult Survey, which provides detailed information on pre- and post-natal behaviors of women from the NLSY79. These women were between the ages of 14 and 22 in 1979, and form a nationally representative sample of youth in the United States. Our sample includes births to these women between 1973 and 2010 (10,328 births to 3755 mothers). We use fixed effects regression models to estimate within-mother differences in pre- and post-natal behaviors across births. We find that mothers are 6.6 percent less likely to take prenatal vitamins in a fourth or higher-order birth than in a first and are 10.6 percent less likely to receive early prenatal care. Remarkably, mothers are 15.4 percent less likely to breastfeed a second-born child than a first, and are 20.9 percent less likely to breastfeed a fourth or higher-order child. These results are not explained by changing attitudes toward investments over time. These findings suggest that providers may want to increase efforts to encourage these behaviors at women with higher parity. The results also identify a potential mechanism for the emergence of differences in health and other outcomes across birth orders. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Focal musculoskeletal anomalies vary, and can manifest as part of a syndrome or be accompanied by numerous other conditions such as genetic disorders, karyotype abnormalities, central nervous system anomalies and other skeletal anomalies, lsolated focal musculoskeletal anomaly does, however, also occur; its early prenatal diagnosis is important in deciding prenatal care, and also helps in counseling parents about the postnatal effects of numerous possible associated anomalies. We have encountered 50 cases involving focal musculoskeletal anomalies, including total limb dysplasia [radial ray abnormality (n=3), mesomelic dysplasia (n=1)]; anomalies of the hand [polydactyly (n=8), syndactyly (n=3), ectrodactyly (n=1), clinodactyly (n=6), clenched hand (n=5)]; anomalies of the foot [clubfoot (n=10), rockerbottom foot (n=5), sandal gap deformity (n=1), curly toe (n=2)]; amniotic band syndrome (n=3); and anomalies of the focal spine [block vertebra (n=1), hemivertebra (n=1)]. Among these 50 cases, five [polydactyly (n=1), syndactyly (n=2) and curly toe (n=2) were confirmed by postnatal physical evaluation, two (focal spine anomalies) were diagnosed after postnatal radiologic examination, and the remaining 43 were proven at autopsy.

    Multiple studies have demonstrated improved perinatal outcomes for group prenatal care (GPC) when compared to traditional prenatal care. Benefits of GPC include lower rates of prematurity and low birth weight, fewer cesarean deliveries, improved breastfeeding outcomes and improved maternal satisfaction with care. However, the outpatient financial costs of running a GPC program are not well established. This study involved the creation of a financial model that forecasted costs and revenues for prenatal care groups with various numbers of participants based on numerous variables, including patient population, payor mix, patient show rates, staffing mix, supply usage and overhead costs. The model was developed for use in an urban underserved practice. Adjusted revenue per pregnancy in this model was found to be $989.93 for traditional care and $1080.69 for GPC. Cost neutrality for GPC was achieved when each group enrolled an average of 10.652 women with an enriched staffing model or 4.801 women when groups were staffed by a single nurse and single clinician. Mathematical cost-benefit modeling in an urban underserved practice demonstrated that GPC can be not only financially sustainable but possibly a net income generator for the outpatient clinic. Use of this model could offer maternity care practices an important tool for demonstrating the financial practicality of GPC.

    Background Paracetamol is used extensively during pregnancy, but studies regarding the potential neurodevelopmental sequelae of foetal paracetamol exposure are lacking. Method Between 1999 and 2008 all pregnant Norwegian women were eligible for recruitment into the prospective Norwegian Mother and Child Cohort Study. The mothers were asked to report on their use of paracetamol at gestational weeks 17 and 30 and at 6 months postpartum. We used data on 48 631 children whose mothers returned the 3-year follow-up questionnaire by May 2011. Within this sample were 2919 same-sex sibling pairs who were used to adjust for familial and genetic factors. We modelled psychomotor development (communication, fine and gross motor development), externalizing and internalizing behaviour problems, and temperament (emotionality, activity, sociability and shyness) based on prenatal paracetamol exposure using generalized linear regression, adjusting for a number of factors, including febrile illness, infections and co-medication use during pregnancy. Results The sibling-control analysis revealed that children exposed to prenatal paracetamol for more than 28 days had poorer gross motor development [β 0.24, 95% confidence interval (CI) 0.12–0.51], communication (β 0.20, 95% CI 0.01–0.39), externalizing behaviour (β 0.28, 95% CI 0.15–0.42), internalizing behaviour (β 0.14, 95% CI 0.01–0.28), and higher activity levels (β 0.24, 95% CI 0.11–0.38). Children exposed prenatally to short-term use of paracetamol (1–27 days) also had poorer gross motor outcomes (β 0.10, 95% CI 0.02–0.19), but the effects were smaller than with long-term use. Ibuprofen exposure was not associated with neurodevelopmental outcomes. Conclusion Children exposed to long-term use of paracetamol during pregnancy had substantially adverse developmental outcomes at 3 years of age. PMID:24163279

    To identify prenatal and perinatal risk factors for childhood asthma. A retrospective case-control study was undertaken among children aged 7-14 years in Tehran, Iran, between March 2009 and November 2014. Data for children with asthma (Iranian nationality, non-smoking parents, and middle-class socioeconomic status) were compared with those for an equal number of age- and sex-matched non-asthmatic children. Prenatal and perinatal risk factors were evaluated via complete data sheets of maternal pregnancy and delivery. Forward logistic regression analysis was performed. Both groups contained 134 children. Risk of asthma was shown to be associated with maternal history of asthma (adjusted odds ratio [aOR] 11.62, 95% confidence interval 1.38-96.93; P=0.024), vaginal bleeding during pregnancy (aOR 3.76, 95% CI 1.86-7.57; Pchildhood asthma (aOR 0.29, 95% CI 0.151-0.575; Pasthma was the most influential factor on development of childhood asthma, followed by vaginal bleeding during pregnancy, antibiotic exposure in utero, and older maternal age. © 2017 International Federation of Gynecology and Obstetrics.

    Neurodevelopmental outcome in children with agenesis of the corpus callosum (ACC) is correlated with the presence or absence of associated brain abnormalities. Indeed, neurodevelopmental outcome shows severe disabilities when the ACC is not isolated whereas in isolated forms, the neurologic development is mainly normal. Contrary to data in several published studies, the prognosis remains uncertain even in isolated forms, which may lead in France to medical termination of pregnancy. To evaluate long-term neurodevelopmental outcome in children with prenatally diagnosed isolated ACC. This is a follow-up study conducted in Normandy (France). It included a cohort of 25 children born between January 1991 and June 2016, with a prenatal diagnosis of isolated ACC and who were followed for at least two years. The average follow-up was 8±5years. ACC was complete in 17 patients (68%), partial in 5 (20%) and hypoplastic in 3 (12%). Whereas global motor development was normal in each case, normal neurodevelopmental outcome or mild disabilities occurred in 88% children and moderate/severe neuro-disabilities were present in 12% of children. Wechsler Intelligence Scale for Children-IV evaluations and Intellectual Total Quotients were within normal range, but we observed lower scores in verbal comprehension, social judgment, executive functions. A lower score in morphosyntax was observed among 52% of children with oral language disorders. Neurodevelopmental outcome was favorable in most of our patients with isolated ACC, but mild learning disabilities emerged in older children. Long-term follow-up until school age is essential to provide early diagnosis and appropriate care support. Copyright © 2017 Elsevier B.V. All rights reserved.

    Individual prenatal care is intended to prevent poor perinatal outcomes and provide education to women throughout pregnancy, childbirth, and the postpartum period through a series of one-on-one encounters between a woman and her obstetrician or other obstetric care provider. Concerns regarding increasing health care costs, health care provider availability, dissatisfaction with wait times, and the minimal opportunity for education and support associated with the individual care model have given rise to interest in alternative models of prenatal care. One alternative model, group prenatal care, may be beneficial or preferred for some practice settings and patient populations, although individual prenatal care remains standard practice. Group prenatal care models are designed to improve patient education and include opportunities for social support while maintaining the risk screening and physical assessment of individual prenatal care. Bringing patients with similar needs together for health care encounters increases the time available for the educational component of the encounter, improves efficiency, and reduces repetition. Evidence suggests patients have better prenatal knowledge, feel more ready for labor and delivery, are more satisfied with care in prenatal care groups, and initiate breastfeeding more often. There is no evidence that suggests that group prenatal care causes harm. Individual and group care models warrant additional study with a goal of demonstrating differences in outcomes and identifying populations that benefit most from specific care models.

    estimates is low and possible consequences if the test reveals a problem is seldom considered beforehand. A woman's attitude to prenatal examinations is found decisive for up-take of prenatal tests, with no association between a woman's attitude towards prenatal examinations and her knowledge of those tests....... Most women consider their doctor an important source of information, and state that information has influenced their decision.      Conclusions: Pregnant women favor prenatal examinations, but participation does not seem to be based on an informed consent....

    A key question in understanding gender development concerns the origins of sex segregation. Children's tendencies to interact with same-sex others have been hypothesized to result from gender identity and cognitions, behavioral compatibility, and personal characteristics. We examined whether prenatal androgen exposure was related to time spent with boys and girls, and how that gendered peer involvement was related to sex-typed activities and gender identity and cognitions. We studied 54 girls with congenital adrenal hyperplasia (CAH) aged 10-13 years varying in degree of prenatal androgen exposure: 40 girls with classical CAH (C-CAH) exposed to high prenatal androgens and 14 girls with non-classical CAH (NC-CAH) exposed to low, female-typical, prenatal androgens. Home interviews and questionnaires provided assessments of gendered activity interests and participation, gender identity, and gender cognitions. Daily phone calls over 7 days assessed time spent in gendered activities and with peers. Girls with both C-CAH and NC-CAH interacted more with girls than with boys, with no significant group differences. The groups did not differ significantly in gender identity or gender cognitions, but girls with C-CAH spent more time in male-typed activities and less time in female-typed activities than did girls with NC-CAH. Time spent with girls reflected direct effects of gender identity/cognitions and gender-typed activities, and an indirect effect of prenatal androgens (CAH type) through gender-typed activities. Our results extend findings that prenatal androgens differentially affect gendered characteristics and that gendered peer interactions reflect combined effects of behavioral compatibility and feelings and cognitions about gender. The study also shows the value of natural experiments for testing hypotheses about gender development.

Prenatal exposure to AP medication has been associated with several adverse outcomes, but the findings remain inconsistent.Purpose: We aimed to investigate prenatal exposure to AP medication and the use of primary health care system in childhood.Subjects and methods: All live-born singletons in Denmark during 1997–2012 were identified in the nationwide Danish National Patient Register and followed until December 31, 2013 (n = 963,010. Information on prenatal exposure to AP medication was obtained from the Danish Register of Medicinal Product Statistics. Contacts to the general practitioner (GP were used as a proxy for the overall health of the children. Negative binomial regression was used to calculate incidence rate ratios (IRRs and 95% confidence intervals (CIs for the association between prenatal exposure to AP medication and number and type of GP contacts, excluding routine well-child visits and vaccinations. The models were adjusted for sex and birth date of the child, maternal age, parity, cohabitation status, income, education, smoking status, diagnosis of substance abuse, severe psychiatric disorder, depression and epilepsy as well as the use of antiepileptic drugs, antidepressants, benzodiazepines and insulin.Results: The prenatally AP-exposed children had 7% more GP contacts than unexposed children, IRR: 1.07 (95% CI: 1.03, 1.11.

    People worldwide depend upon daily fish consumption as a major source of protein and other nutrients. Fish are high in nutrients essential for normal brain development, but they also contain methylmercury (MeHg), a neurotoxicant. Our studies in a population consuming fish daily have indicated no consistent pattern of adverse associations between prenatal MeHg and children's development. For some endpoints we found performance improved with increasing prenatal exposure to MeHg. Follow up studies indicate this association is related to the beneficial nutrients present in fish. To determine if the absence of adverse outcomes and the presence of beneficial associations between prenatal MeHg and developmental outcomes previously reported persists into adolescence. This study was conducted on the Main Cohort of the Seychelles Child Development Study (SCDS). We examined the association between prenatal MeHg exposure and subjects' performance at 17 years of age on 27 endpoints. The test battery included the Wisconsin Card Sorting Test (WCST), the California Verbal Learning Test (CVLT), the Woodcock-Johnson (W-J-II) Achievement Test, subtests of the Cambridge Neuropsychological Test Automated Battery (CANTAB), and measures of problematic behaviors. Analyses for all endpoints were adjusted for postnatal MeHg, sex, socioeconomic status, maternal IQ, and child's age at testing and the child's IQ was added for problematic behavioral endpoints. Mean prenatal MeHg exposure was 6.9 ppm. There was no association between prenatal MeHg and 21 endpoints. Increasing prenatal MeHg was associated with better scores on four endpoints (higher W-J-II math calculation scores, reduced numbers of trials on the Intra-Extradimensional Shift Set of the CANTAB), fewer reports of substance use and incidents of and referrals for problematic behaviors in school. Increasing prenatal MeHg was adversely associated with one level of referrals to a school counselor. At age 17 years there was no consistent

    To compare the psychosocial outcomes of the CenteringPregnancy (CP) model of group prenatal care to individual prenatal care, we conducted a prospective cohort study of women who chose CP group (N = 124) or individual prenatal care (N = 124). Study participants completed the first survey at study recruitment (mean gestational age 12.5 weeks), with 89% completing the second survey (mean gestational age 32.7 weeks) and 84% completing the third survey (6 weeks' postpartum). Multiple linear regression models compared changes by prenatal care model in pregnancy-specific distress, prenatal planning-preparation and avoidance coping, perceived stress, affect and depressive symptoms, pregnancy-related empowerment, and postpartum maternal-infant attachment and maternal functioning. Using intention-to-treat models, group prenatal care participants demonstrated a 3.2 point greater increase (p prenatal planning-preparation coping strategies. While group participants did not demonstrate significantly greater positive outcomes in other measures, women who were at greater psychosocial risk benefitted from participation in group prenatal care. Among women reporting inadequate social support in early pregnancy, group participants demonstrated a 2.9 point greater decrease (p = 0.03) in pregnancy-specific distress in late pregnancy and 5.6 point higher mean maternal functioning scores postpartum (p = 0.03). Among women with high pregnancy-specific distress in early pregnancy, group participants had an 8.3 point greater increase (p prenatal planning-preparation coping strategies in late pregnancy and a 4.9 point greater decrease (p = 0.02) in postpartum depressive symptom scores. This study provides further evidence that group prenatal care positively impacts the psychosocial well-being of women with greater stress or lower personal coping resources. Large randomized studies are needed to establish conclusively the biological and psychosocial benefits of group

    Full Text Available Recent developments in molecular genetics improved our knowledge on fetal genome and physiology. Novel scientific innovations in prenatal diagnosis have accelerated in the last decade changing our vision immensely. Data obtained from fetal genomic studies brought new insights to fetal medicine and by the advances in fetal DNA and RNA sequencing technology novel treatment strategies has evolved. Non-invasive prenatal diagnosis found ground in genetics and the results are widely studied in scientific arena. When Lo and colleges proved fetal genetic material can be extracted from maternal plasma and fetal DNA can be isolated from maternal serum, the gate to many exciting discoveries was open. Microarray technology and advances in sequencing helped fetal diagnosis as well as other areas of medicine. Today it is a very crucial prerequisite for physicians practicing prenatal diagnosis to have a profound knowledge in genetics. Prevailing practical use and application of fetal genomic tests in maternal and fetal medicine mandates obstetricians to update their knowledge in genetics. The purpose of this review is to assist physicians to understand and update their knowledge in fetal genetic testing from maternal blood, individualized prenatal counseling and advancements on the subject by sharing our experiences as İstanbul University Fetal Nucleic Acid Research Group.

    2006-09-01

    Full Text Available Abstract Background Despite the wide availability of prenatal screening and diagnosis, a number of studies have reported no decrease in the rate of babies born with Down syndrome. The objective of this study was to investigate the geodemographic characteristics of women who have prenatal diagnosis in Victoria, Australia, by applying a novel consumer behaviour modelling technique in the analysis of health data. Methods A descriptive analysis of data on all prenatal diagnostic tests, births (1998 and 2002 and births of babies with Down syndrome (1998 to 2002 was undertaken using a Geographic Information System and socioeconomic lifestyle segmentation classifications. Results Most metropolitan women in Victoria have average or above State average levels of uptake of prenatal diagnosis. Inner city women residing in high socioeconomic lifestyle segments who have high rates of prenatal diagnosis spend 20% more on specialist physician's fees when compared to those whose rates are average. Rates of prenatal diagnosis are generally low amongst women in rural Victoria, with the lowest rates observed in farming districts. Reasons for this are likely to be a combination of lack of access to services (remoteness and individual opportunity (lack of transportation, low levels of support and income. However, there are additional reasons for low uptake rates in farming areas that could not be explained by the behaviour modelling. These may relate to women's attitudes and choices. Conclusion A lack of statewide geodemographic consistency in uptake of prenatal diagnosis implies that there is a need to target health professionals and pregnant women in specific areas to ensure there is increased equity of access to services and that all pregnant women can make informed choices that are best for them. Equally as important is appropriate health service provision for families of children with Down syndrome. Our findings show that these potential interventions are

    2017-01-01

    BACKGROUND Cardiac rhabdomyoma (CRs) are the most common primary tumour of the heart in infants and children. Usually are multiple and, basing on the location can cause a haemodynamic disturbance, dysrhythmias or heart failure during the fetal and early postnatal period. CRs have a natural history of spontaneous regression and are closely associated with tuberous sclerosis complex (TSC). It has an association with tuberous sclerosis (TS), and in those, the tumour may regress and disappear completely, or remain consistent in size. AIM: We aimed to evaluate the prenatal diagnosis, clinical presentation and outcome of CRs and their association with TSC in a single centre. The median follow-up period was three years (range: 6 months - 5 years). MATERIAL AND METHODS: We reviewed medical records of all fetuses diagnosed prenatally with cardiac rhabdomyoma covering the period January 2010 to December 2016 which had undergone detailed ultrasound evaluation at a single centre with limited technical resources. RESULTS: Twelve fetuses were included in the study; mostly had multiple tumours and a total of 53 tumours were identified in all patients - the maximum was one fetus with16 tumours. All patients were diagnosed prenatally by fetal echocardiography. In two patient’s haemodynamic disturbances during the fetal period was noted and pregnancies have been terminated. After long consultation termination of pregnancy was chosen by the parents in totally 8 cases. In four continuing pregnancies during the first year of live tumours regressed. TSC was diagnosed in all patients during the follow-up. CONCLUSIONS: Cardiac rhabdomyoma are benign from the cardiovascular standpoint in most affected fetuses. An early prenatal diagnosis may help for an adequate planning of perinatal monitoring and treatment with the involvement of a multidisciplinary team. Large tumour size, the number of tumours and localisation may cause hydrops, and they are significantly associated with poor

  16. Maternal prenatal distress and poor nutrition – mutually influencing risk factors affecting infant neurocognitive development

    2012-01-01

    Background Accumulating data from animal and human studies indicate that the prenatal environment plays a significant role in shaping children’s neurocognitive development. Clinical, epidemiologic, and basic science research suggests that two experiences relatively common in pregnancy — an unhealthy maternal diet and psychosocial distress — significantly affect children’s future neurodevelopment. These prenatal experiences exert their influence in the context of one another and yet, almost uniformly, are studied independently. Scope and Method of Review In this review, we suggest that studying neurocognitive development in children in relation to both prenatal exposures is ecologically most relevant, and methodologically most sound. To support this approach, we selectively review two research topics that demonstrate the need for dual exposure studies, including exemplar findings on (1) the associations between pregnant women’s inadequate maternal intake of key nutrients – protein, fat, iron, zinc, and choline – as well as distress in relation to overlapping effects on children’s neurocognitive development; and (2) cross-talk between the biology of stress and nutrition that can amplify each experience for the mother and fetus,. We also consider obstacles to this kind of study design, such as questions of statistical methods for ‘disentangling’ the exposure effects, and aim to provide some answers. Conclusion Studies that specifically include both exposures in their design can begin to determine the relative and/or synergistic impact of these prenatal experiences on developmental trajectories — and thereby contribute most fully to the understanding of the early origins of health and disease.

    2012-01-01

    Objectives The broad goal of contemporary prenatal care is to promote the health of the mother, child, and family through the pregnancy, delivery, and the child’s development. Although the vast majority of mothers giving birth in developed countries receive prenatal care, past research has not found compelling evidence that early or adequate prenatal care has favorable effects on birth outcomes. It is possible that prenatal care confers health benefits to the child that do not become apparent until after the perinatal period. Methods Using data from a national urban birth cohort study in the U.S., we estimate the effects of prenatal care on four markers of child health at age 5—maternal-reported health status, asthma diagnosis, overweight, and height. We implement a number of different strategies to address the issue of potential omitted variables bias as well as a large number of specification checks to validate the findings. Results and Conclusions Prenatal care, defined a number of different ways, does not appear to have any effect on the outcomes examined. The findings are robust and suggest that routine health care encounters during the prenatal period could potentially be used more effectively to enhance children’s health trajectories. However, future research is needed to explore the effects of prenatal care on additional child health and developmental outcomes as well as the effects of preconceptional and maternal lifetime helathcare on child health.

    To compare gestational weight gain among women in group prenatal care with that of women in individual prenatal care. In this retrospective cohort study, women who participated in group prenatal care from 2009 to 2015 and whose body mass indexes (BMIs) and gestational weight gain were recorded were matched with the next two women who had the same payer type, were within 2-kg/m prepregnancy BMI and 2-week gestational age at delivery, and had received individual prenatal care. Bivariate comparisons of demographics and antenatal complications were performed for women in group and individual prenatal care, and weight gain was categorized as "below," "met," or "exceeded" goals according to the 2009 Institute of Medicine guidelines. Logistic regression analysis estimated the association between excessive weight gain and model of care, with adjustment for confounders, stratified by BMI. Women in group prenatal care (n=2,117) were younger and more commonly non-Hispanic black, nulliparous, and without gestational diabetes (P≤.005 for all). Women in group prenatal care more commonly exceeded the weight gain goals (55% compared with 48%, Pprenatal care, compared with individual prenatal care, is associated with excessive gestational weight gain.

  3. The Paradigm of Unity in Prenatal Education and Pedagogy

    Directory of Open Access Journals (Sweden)

    Kornas-Biela Dorota

    2014-07-01

    Full Text Available The traditional approach to the relation between parents and their prenatal child presents the child as a fetus, a mainly passive recipient of the mother’s vital biological resources. Contemporary prenatal psychology and pedagogy recognizes this relationship in a quite different perspective: the prenatal child is a member of the family and may be seen as an active member of the wider family as a community, extended to grandparents and other relatives. Between parents and their child in the womb exists a reciprocal relationship at a physiological (hormonal, psychological and spiritual level. The prenatal child communicates with the parents in different ways and reacts to their stimulation (acoustic, tactile, loco-motoric, chemo-receptive, thermo-receptive, and emotional. This dialogue of the parents and their prenatal child enriches each member of the family community. In this sense, the prenatal child is a gift and a challenge for the parents to develop their personality, social competences and spiritual life. The reflections presented in this paper fit the conception of the paradigm of unity applied into the area of prenatal education and prenatal pedagogy as a new pedagogical subdisciline.

    Exposure to prenatal and early-life stress results in alterations in neural connectivity and an increased risk for neuropsychiatric disorders. In particular, alterations in amygdala connectivity have emerged as a common effect across several recent studies. However, the impact of prenatal stress exposure on the functional organization of the amygdala has yet to be explored in the prematurely-born, a population at high risk for neuropsychiatric disorders. We test the hypothesis that preterm birth and prenatal exposure to maternal stress alter functional connectivity of the amygdala using two independent cohorts. The first cohort is used to establish the effects of preterm birth and consists of 12 very preterm neonates and 25 term controls, all without prenatal stress exposure. The second is analyzed to establish the effects of prenatal stress exposure and consists of 16 extremely preterm neonates with prenatal stress exposure and 10 extremely preterm neonates with no known prenatal stress exposure. Standard resting-state functional magnetic resonance imaging and seed connectivity methods are used. When compared to term controls, very preterm neonates show significantly reduced connectivity between the amygdala and the thalamus, the hypothalamus, the brainstem, and the insula (p amygdala and the thalamus, the hypothalamus, and the peristriate cortex (p amygdala connectivity associated with preterm birth. Functional connectivity from the amygdala to other subcortical regions is decreased in preterm neonates compared to term controls. In addition, these data, for the first time, suggest that prenatal stress exposure amplifies these decreases.

    Prenatal care is a pillar of public health, enabling access to interventions including prevention of mother-to-child transmission of HIV and congenital syphilis. This paper describes social factors related to use of prenatal care in Ecuador. In 2011 and 2012, participant clinical history and interview information was analyzed from a national probability sample of 5 998 women presenting for delivery or miscarriage services in 15 healthcare facilities in Ecuador, to estimate prevalence of HIV, syphilis, and Chagas disease, and prenatal care coverage. The study found that 94.1% of women had attended at least one prenatal visit, but that attendance at no less than four visits was 73.1%. Furthermore, lower educational level, greater number of pregnancies, occupation in the agriculture or livestock sector, and membership in ethnic indigenous, Afro-Ecuadorian, or other minority groups were factors associated with lack of use (no prenatal visits) or insufficient use of prenatal care (fewer than four visits or first visit at >20 weeks gestation) in Ecuador. These results point to persistence of marked inequalities in access to and use of prenatal health services attributable to socioeconomic factors and to the need to strengthen strategies to address them, to reach the goal of universal prenatal care coverage.

    Prenatal breastfeeding education increases breastfeeding initiation, exclusivity, and duration. Current research regarding antenatal breastfeeding education suggests that recurrent, individual, and technology-based education programs are effective in providing women with evidence-based breastfeeding information and guidance. This project was implemented at an obstetrical practice in the northeast United States. Pregnant women between 32 weeks of gestation and birth, receiving care from certified nurse-midwives, were the targeted population. Three breastfeeding modules were created and offered to women at the 32-, 34-, and 36-week prenatal visit via computer tablets. Women answered questionnaires at the end of each module, serving as a measure for participation and content learning. Women also completed a questionnaire at the 6-week postpartum visit to assess summative perceptions. Twenty-three women participated, and 21 women completed questionnaires at 6 weeks postpartum. All women answered the content questions at the end of the modules correctly. Sixty-seven percent reported prior breastfeeding experience, 95% initiated breastfeeding, 86% were exclusively breastfeeding at 6 weeks postpartum, and 71% of the women planned to exclusively breastfeed for 6 months. Sixty-seven percent reported the modules promoted or affirmed their decision to breastfeed, whereas 5% would have preferred group-based education. Providers documented breastfeeding education 52% of the time. The results of this project indicate that women successfully learned breastfeeding content via the tablet methodology. The results confirm that prenatal breastfeeding education, in the office setting, is well accepted by women. In order to assess the impact of the program on breastfeeding success, further study is needed.

  16. Prenatal stressors in rodents: Effects on behavior

    2017-02-01

    Full Text Available The current review focuses on studies in rodents published since 2008 and explores possible reasons for any differences they report in the effects of gestational stress on various types of behavior in the offspring. An abundance of experimental data shows that different maternal stressors in rodents can replicate some of the abnormalities in offspring behavior observed in humans. These include, anxiety, in juvenile and adult rats and mice, assessed in the elevated plus maze and open field tests and depression, detected in the forced swim and sucrose-preference tests. Deficits were reported in social interaction that is suggestive of pathology associated with schizophrenia, and in spatial learning and memory in adult rats in the Morris water maze test, but in most studies only males were tested. There were too few studies on the novel object recognition test at different inter-trial intervals to enable a conclusion about the effect of prenatal stress and whether any deficits are more prevalent in males. Among hippocampal glutamate receptors, NR2B was the only subtype consistently reduced in association with learning deficits. However, like in humans with schizophrenia and depression, prenatal stress lowered hippocampal levels of BDNF, which were closely correlated with decreases in hippocampal long-term potentiation. In mice, down-regulation of BDNF appeared to occur through the action of gene-methylating enzymes that are already increased above controls in prenatally-stressed neonates. In conclusion, the data obtained so far from experiments in rodents lend support to a physiological basis for the neurodevelopmental hypothesis of schizophrenia and depression.

    We sought to evaluate the prenatal decision-making of pregnant adolescents identified at increased risk for identifiable fetal genetic abnormalities. A retrospective review of records of gravid women 19 years old or younger undergoing genetic counseling from 2001-2003 (inclusive) was undertaken. Hospital-based academic center. Thirty-seven women were identified; four cases did not meet inclusion criteria. None. Decision to undergo or forgo invasive prenatal testing. Of the 33 women included in this study, the average age was 17.6 years (range: 15-19). Eighteen were Latinas, eight were African-Americans, and seven were Caucasians. Sixteen women had positive maternal serum screening outcomes; nine women sought counseling because of personal/family histories of genetic abnormalities, seven sought counseling after fetal structural anomalies were detected by ultrasound, and one woman sought counseling because she and her partner were positive for Mendelian disorder screening (sickle cell disease). Sixteen of the women (48.5%) chose to undergo invasive testing (15 amniocenteses, one chorionic villus sampling) whereas 17 (51.5%) chose to forgo invasive testing. Adolescents offered invasive prenatal diagnosis will chose to undergo or forgo such testing based on diagnostic and personal criteria as do adult women. Nonetheless, unique adolescent issues may make the process by which information is obtained and communicated during counseling to be different from counseling provided to adults. The development of new genetic screening and diagnostic protocols has and will increase the number of pregnant adolescent women who will be offered genetic counseling during their pregnancies. Such an increase in numbers will place considerably more pressure on an already taxed genetic counseling system; accordingly, new counseling paradigms will need to be developed to provide service to an expanded patient population seeking information for an increasing number of genetic issues.

    Activation of gene transcription by radiation has been recently demonstrated in vivo. However, little is known on the specificity of these alterations on gene transcription. Prenatal irradiation is a known teratogen that affects the developing mammalian central nervous system (CNS). Altered neuronal migration has been suggested as a mechanism for abnormal development of prenatally irradiated brains. Fibronectin (FN), an extracellular glycoprotein, is essential for neural crest cell migration and neural cell growth. In addition, elevated levels of FN have been found in the extracellular matrix of irradiated lung. To test whether brain FN is affected by radiation, either FN level in insoluble matrix fraction or expression of FN mRNA was examined pre- and postnatally after irradiation. Mice (CD1), at 13 d of gestation (DG), served either as controls or were irradiated with 14 DG, 17 DG, or 5,6, or 14 d postnatal. Brain and liver were collected from offspring and analyzed for either total FN protein levels or relative mRNAs for FN and tubulin. Results of prenatal irradiation on reduction of postnatal brain weight relative to whole are comparable to that reported by others. Insoluble matrix fraction (IMF) per gram of brain, liver, lung, and heart weight was not significantly different either between control and irradiated groups or between postnatal stages, suggesting that radiation did not affect the IMF. However, total amounts of FN in brain IMF at 17 DG were significantly different (p < .02) between normal (1.66 ± 0.80 μg) and irradiated brains (0.58 ± 0.22 μg). FN mRNA was detectable at 13, 14, and 17 DG, but was not detectable at 6 and 14 d postnatal, indicating that FN mRNA is developmentally regulated. 41 refs., 4 figs., 3 tabs

    The migrational disorders are a rare group of congenital malformations of the brain seen in children. They are primarily cortical and gray matter abnormalities. Forty patients, divided into two groups, were studied. In one group were patients with the classic migrational lesions of lissencephaly, pachygyria, schizencephaly, heterotopia, and polymicrogyria in which the underlying cause is genetic, chromosomal, or unknown. In the second group were patients with lesions caused by a prenatally acquired infection (toxoplasmosis or cytomegalic virus) or a metabolic abnormality. The CT and MR imaging findings in these two groups are discussed

    Background Prenatal exposure to traffic pollution has been associated with faster infant weight gain, but implications for cardiometabolic health in later childhood are unknown. Methods Among 1,418 children in Project Viva, a Boston-area pre-birth cohort, we assessed anthropometric and biochemical parameters of cardiometabolic health in early (median age 3.3 years) and mid- (median age 7.7 years) childhood. We used spatiotemporal models to estimate prenatal and early life residential PM2.5 and black carbon exposure as well as traffic density and roadway proximity. We performed linear regression analyses adjusted for sociodemographics Results Children whose mothers lived close to a major roadway at the time of delivery had higher markers of adverse cardiometabolic risk in early and mid-childhood. For example, total fat mass was 2.1kg (95%CI: 0.8, 3.5) higher in mid-childhood for children of mothers who lived < 50 m vs. ≥ 200m from a major roadway. Black carbon exposure and traffic density were generally not associated with cardiometabolic parameters, and PM2.5 exposure during the year prior was paradoxically associated with improved cardiometabolic profile Conclusions Infants whose mothers lived close to a major roadway at the time of delivery may be at later risk for adverse cardiometabolic health.

    Experimental animal studies suggest that early glucocorticoid exposure may have lasting effects on the neurodevelopment of the offspring; animal studies also suggest that this effect may be eliminated by positive postnatal rearing. The relevance of these findings to humans is not known. We prospectively followed 125 mothers and their normally developing children from pregnancy through 17 months postnatal. Amniotic fluid was obtained at, on average, 17.2 weeks gestation; infants were assessed at an average age of 17 months with the Bayley Scales of Infant Development, and ratings of infant-mother attachment classification were made from the standard Ainsworth Strange Situation assessment. Prenatal cortisol exposure, indexed by amniotic fluid levels, negatively predicted cognitive ability in the infant, independent of prenatal, obstetric, and socioeconomic factors. This association was moderated by child-mother attachment: in children with an insecure attachment, the correlation was [r(54) = -.47, p < .001]; in contrast, the association was nonexistent in children who had a secure attachment [r(70) = -.05, ns]. These findings mimic experimental animal findings and provide the first direct human evidence that increased cortisol in utero is associated with impaired cognitive development, and that its impact is dependent on the quality of the mother-infant relationship.

    Two cases of dyssegmental dysplasia (type Silverman-Handmaker) in siblings are presented. The first-born died at the age of 3 months and the second fetus was followed during pregnancy with ultrasound examinations. In the 20th week of gestation marked shortening of the extremities was found; a female infant showing the same radiologic bony malformations as the firstborn was born by cesarean section. These cases support the autosomal recessive inheritance and demonstrate the possibility of prenatal diagnosis in this type of micromelic dwarfism. (orig.)

    We studied congenital hydrocephalus in 14 patients who were diagnosed prenatally. As a result, we obtained the following insights concerning the prenatal diagnosis by MRI (magnetic resonance imaging) and perinatal management of congenital hydrocephalus. Accurate diagnosis of congenital hydrocephalus was impossible prenatally by two-dimensional ultrasonography or computed tomography alone in some patients. MRI was useful for accurate prenatal diagnosis. Problem of MRI in prenatal diagnosis included deterioration of the image by fetal movements and safety concern over the fetus. The cause of hydrocephalus, complicated anomaly, cerebral cortical thickness, and gestational age must be considered in the perinatal management of congenital hydrocephalus. There appeared to be a chance of recovery to a certain extent from thinning of cerebral cortex by decompression in a patient in whom dilation of cerebral ventricles progressed rapidly. (author)

  7. The Motivation-Facilitation Theory of Prenatal Care Access.

    Despite the availability of services, accessing health care remains a problem in the United States and other developed countries. Prenatal care has the potential to improve perinatal outcomes and decrease health disparities, yet many women struggle with access to care. Current theories addressing access to prenatal care focus on barriers, although such knowledge is minimally useful for clinicians. We propose a middle-range theory, the motivation-facilitation theory of prenatal care access, which condenses the prenatal care access process into 2 interacting components: motivation and facilitation. Maternal motivation is the mother's desire to begin and maintain care. Facilitation represents the goal of the clinic to create easy, open access to person-centered beneficial care. This simple model directs the focus of research and change to the interface of the woman and the clinic and encourages practice-level interventions that facilitate women entering and maintaining prenatal care. © 2013 by the American College of Nurse‐Midwives.

    Little is known about neurodevelopment of children exposed to psychotropic drugs during pregnancy. The purpose of this study was to evaluate the effects of prenatal exposure to psychotropic drugs on psychomotor development in children. This observational study used the EFEMERIS database. The database records the drugs prescribed and delivered during pregnancy and the resulting outcomes. Neurodevelopment at nine and 24 months of children born to women exposed to psychotropic drugs (anxiolytics, antidepressants, neuroleptics and anti-epileptics) during the second and/or third trimesters of pregnancy was compared to children who were not exposed to these drugs. Psychomotor development of 493 children (1.5%) exposed to psychotropic drugs during pregnancy was compared to 32 303 unexposed children. Exposure to psychotropic drugs during pregnancy was associated with an increased risk of abnormal motor development at 9 months (OR = 1.3 [1.1-2.2]) and abnormal motor and mental development at 24 months (OR = 4.8 [2.1-11.0] and OR = 2.3 [1.05-4.9]). Increased risk was observed in children born to women exposed to anti-epileptic drugs, neuroleptics or antidepressants during pregnancy. This study found a higher rate of deviation from the normal developmental milestones in children born to women exposed to psychotropic drugs during pregnancy and more particularly antidepressants, neuroleptics and anti-epileptics. © 2016 Société Française de Pharmacologie et de Thérapeutique.

    Chronic psychological stress is a risk factor for osteoporosis. Maternal active mastication during prenatal stress attenuates stress response. The aim of this study is to test the hypothesis that maternal active mastication influences the effect of prenatal stress on bone mass and bone microstructure in adult offspring. Pregnant ddY mice were randomly divided into control, stress, and stress/chewing groups. Mice in the stress and stress/chewing groups were placed in a ventilated restraint tube for 45 minutes, 3 times a day, and was initiated on day 12 of gestation and continued until delivery. Mice in the stress/chewing group were allowed to chew a wooden stick during the restraint stress period. The bone response of 5-month-old male offspring was evaluated using quantitative micro-CT, bone histomorphometry, and biochemical markers. Prenatal stress resulted in significant decrease of trabecular bone mass in both vertebra and distal femur of the offspring. Maternal active mastication during prenatal stress attenuated the reduced bone formation and increased bone resorption, improved the lower trabecular bone volume and bone microstructural deterioration induced by prenatal stress in the offspring. These findings indicate that maternal active mastication during prenatal stress can ameliorate prenatal stress-induced lower bone mass of the vertebra and femur in adult offspring. Active mastication during prenatal stress in dams could be an effective coping strategy to prevent lower bone mass in their offspring.

    Long-chain polyunsaturated fatty acids such as docosahexaenoic acid (DHA) influence immune function and inflammation; however, the influence of maternal DHA supplementation on infant morbidity is unknown. We investigated the effects of prenatal DHA supplementation on infant morbidity. In a double-blind randomized controlled trial conducted in Mexico, pregnant women received daily supplementation with 400 mg of DHA or placebo from 18 to 22 weeks' gestation through parturition. In infants aged 1, 3, and 6 months, caregivers reported the occurrence of common illness symptoms in the preceding 15 days. Data were available at 1, 3, and 6 months for 849, 834, and 834 infants, respectively. The occurrence of specific illness symptoms did not differ between groups; however, the occurrence of a combined measure of cold symptoms was lower in the DHA group at 1 month (OR: 0.76; 95% CI: 0.58-1.00). At 1 month, the DHA group experienced 26%, 15%, and 30% shorter duration of cough, phlegm, and wheezing, respectively, but 22% longer duration of rash (all P ≤ .01). At 3 months, infants in the DHA group spent 14% less time ill (P DHA group experienced 20%, 13%, 54%, 23%, and 25% shorter duration of fever, nasal secretion, difficulty breathing, rash, and "other illness," respectively, but 74% longer duration of vomiting (all P DHA supplementation during pregnancy decreased the occurrence of colds in children at 1 month and influenced illness symptom duration at 1, 3, and 6 months.

  13. ICRP and impairment of mental function following prenatal irradiation

    1992-01-01

    A brief account is given of mental retardation and intelligence testing in unirradiated human populations, without which it is not possible to judge the 1991 ICRP Recommendations relating to mental impairment. The dose-response used by ICRP (1991) for the reduction of IQ by irradiation in utero has no radiobiological basis because IQ values are derived from intelligence test scores by transforming the scale of measurement. It is also defective because it assumed that IQ is distributed normally whereas this is so only in normal school children, not in a population in general including retarded persons. There seems good evidence for a substantial threshold of dose for both reduction in IQ and increase in severe mental retardation (SMR). The four prenatally irradiated bomb survivors with SMR and intrauterine dose in the dose range 1-49 cGy were not intelligence tested, so the relation between SMR and IQ in that practically important dose range cannot be examined directly, SMR is a deterministic phenomenon, so is not expected to occur unless dose exceeds a threshold. The threshold doses for SMR based on linear dose-responses using ungrouped doses were 46 and 55 cGy DS86 intrauterine dose (Otake et al 1987). The threshold 50 cGy derived here for reduction in IQ is closely similar. Mild mental retardation has not been reported as a diagnosis in bombs survivors exposed in utero. (Author)

    The practice of prenatal screening is undergoing important changes as a result of the introduction of genomic testing technologies at different stages of the screening trajectory. It is expected that eventually it will become possible to routinely obtain a comprehensive 'genome scan' of all fetuses. Although this will still take several years, there are clear continuities between present developments and this future scenario. As this review shows, behind the still limited scope of screening for common aneuploidies, a rapid widening of the range of conditions tested for is already taking shape at the invasive testing stage. But the continuities are not just technical; they are also ethical. If screening for Down's syndrome is a matter of providing autonomous reproductive choice, then why would providing the choice to have a full fetal genome scan be something entirely different? There is a clear need for a sustainable normative framework that will have to answer three challenges: the indeterminateness of the autonomy paradigm, the need to acknowledge the future child as an interested stakeholder, and the prospect of broad-scope genomic prenatal screening with a double purpose: autonomy and prevention. © 2015 John Wiley & Sons A/S.

    This study was performed to present the prenatal sonographic findings and the associated abnormalities of acardiac twins. Seven cases of acardiac twins were reviewed retrospectively. Prenatal ultrasonography was performed in all patients at a gestational age between 12 and 27 weeks (mean 17.6 weeks). Autopsy was performed in four cases. The sonographic and autopsy findings were reviewed to report the associated abnormalities of the acardiac and donor fetuses. The diagnosis of acardiac twins was made on the basis of ultrasonography (n=6) or autopsy (n=1). The associated abnormalities of the acardiac fetuses were single umbilical artery (SUA) (n=5), abdominal wall defect (n=4), club feet (n=4), scoliosis (n=1), cleft lip and palate (n=1), digital anomaly (n=1), and umbilical cord cyst (n=1). In four of the donor fetuses, sonographic abnormalities were found. Autopsy was performed in three of the four cases to reveal hydropic change (n=2), diaphragmatic hernia (n=1) and multiple structural abnormalities of interventricular septal defect, polydactyly, club feet and SUA (n=1). Intrauterine fetal death occurred in five donors and follow-up was lost in the remaining two. Meticulous sonography enables the diagnosis of acardiac twins at an early gestational age and can reveal the associated abnormalities of the donor fetus as well as the acardiac fetus

    Full text: Fetal MRI is an already established method in prenatal imaging, with complementary to US role. Most common considerations for fetal MRI are CNS anomalies and urogenital anomalies. Practically, the most frequent indication is ultrasonographically established ventriculomegaly. We introduce our experience in fetal MRI, presenting the distribution of pathological findings and our protocols. We have examined 33 fetuses for a 3-year period. Among these 13 cases were affected by CNS anomalies (neural tube defects, Dandy-Walker, cerebellar hypoplasia, agenesis of corpus callosum, aqueductal atresia, etc.), 11 fetuses are affected by urogenital anomalies (pieloureteral stenosis, VUR, renal agenesis, etc.), 5 with other pathology (congenital tumor, ovarian cysts, etc.) and 4 are normal fetuses. The findings in most interesting cases are reviewed; in some of them we present imaging-pathological correlation and/or follow up imaging. Main advantages of fetal MRI over US consist of acquiring objective and reproducible images, giving the opportunity of multiple expert-leveled reviews; exceptionally high detail concerning CNS-anatomy; additional confidence in excluding presence of concomitant anomalies; independence from calavarial ossification and maternal obesity. Ultrasound remains the main tool for prenatal imaging. MRI has similar sensitivity and higher specificity, thus serving as an arbitrage method and improving accuracy about outcome prognosis

    It is well known that stressful experiences may shape hippocampus-dependent learning and memory processes. However, although most studies focused on the impact of stress at the time of learning or memory testing, very little is known about how stress during critical periods of brain development affects learning and memory later in life. In this study, we asked whether prenatal stress exposure may influence the engagement of hippocampus-dependent spatial learning strategies and caudate nucleus-dependent response learning strategies in later life. To this end, we tested healthy participants whose mothers had experienced major negative life events during their pregnancy in a virtual navigation task that can be solved by spatial and response strategies. We found that young adults with prenatal stress used rigid response learning strategies more often than flexible spatial learning strategies compared with participants whose mothers did not experience major negative life events during pregnancy. Individual differences in acute or chronic stress do not account for these findings. Our data suggest that the engagement of hippocampal and nonhippocampal learning strategies may be influenced by stress very early in life. Copyright © 2012 Wiley Periodicals, Inc.

    A major hallmark of classical congenital adrenal hyperplasia (CAH) is genital ambiguity noted at birth in affected females, which leads to psychological and psychosexual issues in adult life. Attempts to correct genital ambiguity through surgical intervention have been partially successful. Fetal hyperandrogenemia and genital ambiguity have been shown to be preventable by prenatal administration of low-dose dexamethasone initiated before the 9th week of gestation. In 7 of 8 at-risk pregnancies, the unaffected fetus is unnecessarily exposed to dexamethasone for weeks until the diagnosis of classical CAH is ruled out by invasive procedures. This therapeutic dilemma calls for early prenatal diagnosis so that dexamethasone treatment can be directed to affected female fetuses only. We describe the utilization of cell-free fetal DNA in mothers carrying at-risk fetuses as early as 6 gestational weeks by targeted massively parallel sequencing of the genomic region including and flanking the CYP21A2 gene. Our highly personalized and innovative approach should permit the diagnosis of CAH before genital development begins, therefore restricting the purposeful administration of dexamethasone to mothers carrying affected females. © 2016 S.

    Intimate partner violence (IPV) during pregnancy can have serious health consequences for mothers and newborns. The aim of the study is to explore: 1) the influence of experiencing IPV during pregnancy on delayed entry into prenatal care; and 2) whether women's decision-making autonomy and the support for traditional gender roles act to mediate or moderate the relationship between IPV and delayed entry into prenatal care. cross-sectional survey. Multivariate logistic regression models were estimated that control for various socio-demographic and pregnancy related factors to assess whether women who experienced IPV during pregnancy were more likely to delay entry into prenatal care compared with women who had not experienced IPV. The influence of traditional gender roles acceptance and decision-making autonomy were examined both as independent variables and in interaction with IPV, to assess their role as potential mediators or moderators. Chandpur district, Bangladesh. the sample comprised of 426 Bangladeshi women, aged 15-49 years. Postpartum mothers who visited vaccinations centres to receive their children's vaccinations constitute the sampling frame. almost 70% of the women surveyed reported patterns consistent with delayed entry into prenatal care. Accounting for the influence of other covariates, women who experienced physical IPV during pregnancy were 2.61 times more likely (95% CI [1.33, 5.09]) to have delayed entry into prenatal care than their counterparts who did not report physical IPV. Neither sexual nor psychological IPV victimization during pregnancy was linked with late entry into prenatal care. Both gender role attitudes and levels of autonomy mediate the effect of IPV on prenatal care. the results suggest that the high rates of IPV in Bangladesh have effects that can compromise women's health seeking behaviour during pregnancy, putting them and their developing fetus at risk. Specifically, Bangladeshi women who experience physical IPV during

    Studies examining prenatal exposure to mobile phone use and its effect on child neurodevelopment show different results, according to child's developmental stages. To examine neurodevelopment in children up to 36 months of age, following prenatal mobile phone use and radiofrequency radiation (RFR) exposure, in relation to prenatal lead exposure. We analyzed 1198 mother-child pairs from a prospective cohort study (the Mothers and Children's Environmental Health Study). Questionnaires were provided to pregnant women at ≤20 weeks of gestation to assess mobile phone call frequency and duration. A personal exposure meter (PEM) was used to measure RFR exposure for 24h in 210 pregnant women. Maternal blood lead level (BLL) was measured during pregnancy. Child neurodevelopment was assessed using the Korean version of the Bayley Scales of Infant Development-Revised at 6, 12, 24, and 36 months of age. Logistic regression analysis applied to groups classified by trajectory analysis showing neurodevelopmental patterns over time. The psychomotor development index (PDI) and the mental development index (MDI) at 6, 12, 24, and 36 months of age were not significantly associated with maternal mobile phone use during pregnancy. However, among children exposed to high maternal BLL in utero, there was a significantly increased risk of having a low PDI up to 36 months of age, in relation to an increasing average calling time (p-trend=0.008). There was also a risk of having decreasing MDI up to 36 months of age, in relation to an increasing average calling time or frequency during pregnancy (p-trend=0.05 and 0.007 for time and frequency, respectively). There was no significant association between child neurodevelopment and prenatal RFR exposure measured by PEM in all subjects or in groups stratified by maternal BLL during pregnancy. We found no association between prenatal exposure to RFR and child neurodevelopment during the first three years of life; however, a potential combined

    Several persistent organochlorine pollutants (POPs) possess endocrine disrupting abilities, thereby potentially leading to an increased risk of obesity and metabolic diseases, especially if the exposure occurs during prenatal life. We have previously found associations between prenatal POP exposures and increased BMI, waist circumference and change in BMI from 5 to 7 years of age, though only among girls with overweight mothers. In the same birth cohort, we investigated whether prenatal POP exposure was associated with serum concentrations of insulin and leptin among 5-year-old children, thus possibly mediating the association with overweight and obesity at 7 years of age. The analyses were based on a prospective Faroese Birth Cohort (n=656), recruited between 1997 and 2000. Major POPs, polychlorinated biphenyls (PCBs), p,p'-dichlorodiphenyldichloroethylene (DDE) and hexachlorobenzene (HCB), were measured in maternal pregnancy serum and breast milk. Children were followed-up at the age of 5 years where a non-fasting blood sample was drawn; 520 children (273 boys and 247 girls) had adequate serum amounts available for biomarker analyses by Luminex® technology. Insulin and leptin concentrations were transformed from continuous to binary variables, using the 75th percentile as a cut-off point. Multiple logistic regression was used to investigate associations between prenatal POP exposures and non-fasting serum concentrations of insulin and leptin at age 5 while taking into account confounders. Girls with highest prenatal POP exposure were more likely to have high non-fasting insulin levels (PCBs 4th quartile: OR=3.71; 95% CI: 1.36, 10.01. DDE 4th quartile: OR=2.75; 95% CI: 1.09, 6.90. HCB 4th quartile: OR=1.98; 95% CI: 1.06, 3.69) compared to girls in the lowest quartile. No significant associations were observed with leptin, or among boys. A mediating effect of insulin or leptin on later obesity was not observed. These findings suggest, that for girls, prenatal

    The association between childhood exposure to lead (Pb) and deficits in cognitive function is well established. The association with prenatal exposure, however, is not well understood, even though the potential adverse effects are equally important. To evaluate the association between low prenatal exposure to lead and IQ in children, to determine whether there were sex differences in the associations, and to evaluate the moderation effect of prenatal Pb exposure on child IQ. Whole blood samples from pregnant women enrolled in ALSPAC (n=4285) and from offspring at age 30 months (n=235) were analysed for Pb. Associations between prenatal blood lead concentrations (B-Pb) and child IQ at age 4 and 8 years (WPPSI and WISC-III, respectively) were examined in adjusted regression models. There was no association of prenatal lead exposure with child IQ at 4 or 8 years old in adjusted regression models, and no moderation of the association between child B-Pb and IQ. However, there was a positive association for IQ at age 8 years in girls with a predicted increase in IQ (points) per 1μg/dl of: verbal 0.71, performance 0.57, total 0.73. In boys, the coefficients tended to be negative (-0.15, -0.42 and -0.29 points, respectively). Prenatal lead exposure was not associated with adverse effects on child IQ at age 4 or 8 years in this study. There was, however, some evidence to suggest that boys are more susceptible than girls to prenatal exposure to lead. Further investigation in other cohorts is required. Copyright © 2017 The Authors.

    After the Chernobyl accident many countries renewed their radiological emergency plans, also considering the possibility of over boundary accidents. This has been set out by the 96/29/Euratom Directive (Council Directive, 1996), which states that E ach Member State shall ensure that account is taken of the fact that radiological emergencies may occur in connection with practices on or outside its territory and affect it . Moreover, after September 11, 2001, the need to prepare emergency plans for possible terroristic attacks became evident and these plans are now being worked out in many countries for intervention in case of biological, chemical and/or radiological risk. In the event of radiological emergency, all decisions to be taken are based on possible doses to critical groups (European Commission, 1997), which are the population groups most at risk. These critical groups are, in most cases, infants or children, given that dose coefficients for these age groups are generally higher than for adults. However, a new ICRP Recommendation (ICRP, 2001) has recently been published that gives dose coefficients for embryo/foetus due to intake by the mother, by inhalation or ingestion, of 31 radionuclides. Also as a result of the revaluation in the last years of the possible health effects of prenatal exposure to ionising radiation (see e.g. the review in P. Fattibene et al., 1999), the consequences for the embryo/foetus of a possible radiological emergency connected to a nuclear plant and to possible dispersion of Depleted Uranium (DU) in the environment are analysed and discussed in this paper. For the former type of accident, Derived Intervention Levels (DILs) are calculated for prenatal exposure due to acute inhalation by the mother (female member of the public) and an assessment is performed of ingestion doses for the offspring resulting from consumption of foodstuffs by the mother of which 10% of the annual consumption is contaminated at the maximum levels

    There is growing concern that prenatal exposure to bisphenol A (BPA) and phthalates, which are widely used in consumer products, might affect susceptibility to infections and the development of allergy and asthma in children, but there are currently very few prospective studies. We sought to evaluate whether prenatal exposure to BPA and phthalates increases the risk of respiratory and allergic outcomes in children at various ages from birth to 7 years. We measured BPA and metabolites of high-molecular-weight phthalates, 4 di-(2-ethylhexyl) phthalate (DEHP) metabolites (Σ4DEHP) and mono-benzyl phthalate (MBzP), and 3 low-molecular-weight phthalate (LMWP) metabolites (Σ3LMWP) in urine samples collected during the first and third trimesters in pregnant women participating in the Infancia y Medio Ambiente-Sabadell birth cohort study. The occurrence of chest infections, bronchitis, wheeze, and eczema in children was assessed at ages 6 and 14 months and 4 and 7 years through questionnaires given to the mothers. Atopy (specific IgE measurement) and asthma (questionnaire) were assessed at ages 4 and 7 years, respectively. The relative risks (RRs) of wheeze (RR, 1.20; 95% CI, 1.03-1.40; P = .02), chest infections (RR, 1.15; 95% CI, 1.00-1.32; P = .05), and bronchitis (RR, 1.18; 95% CI, 1.01-1.37; P = .04) at any age increased for each doubling in concentration of maternal urinary BPA. Σ4DEHP metabolites were associated with the same outcomes (wheeze: RR, 1.25; 95% CI, 1.04-1.50, P = .02; chest infections: RR, 1.15; 95% CI, 0.97-1.35; P = .11; bronchitis: RR, 1.20; 95% CI, 1.01-1.43; P = .04). MBzP was associated with higher risk of wheeze (RR, 1.15; 95% CI, 1.00-1.33; P = .05). The risk of asthma at age 7 years was also increased with increasing prenatal BPA, Σ4DEHP, and MBzP exposure. There were no other exposure-outcome associations. Prenatal exposure to BPA and high-molecular-weight phthalates might increase the risk of asthma symptoms and respiratory tract

    Polycyclic aromatic hydrocarbons are common carcinogenic and neurotoxic urban air pollutants. Toxic exposures, including air pollution, are disproportionately high in communities of color and frequently co-occur with chronic economic deprivation. We examined whether the association between child IQ and prenatal exposure to polycyclic aromatic hydrocarbons differed between groups of children whose mothers reported high vs. low material hardship during their pregnancy and through child age 5. We tested statistical interactions between hardships and polycyclic aromatic hydrocarbons, as measured by DNA adducts in cord blood, to determine whether material hardship exacerbated the association between adducts and IQ scores. Prospective cohort. Participants were recruited from 1998 to 2006 and followed from gestation through age 7 years. Urban community (New York City) A community-based sample of 276 minority urban youth EXPOSURE MEASURE: Polycyclic aromatic hydrocarbon-DNA adducts in cord blood as an individual biomarker of prenatal polycyclic aromatic hydrocarbon exposure. Maternal material hardship self-reported prenatally and at multiple timepoints through early childhood. Child IQ at 7 years assessed using the Wechsler Intelligence Scale for Children. Significant inverse effects of high cord PAH-DNA adducts on full scale IQ, perceptual reasoning and working memory scores were observed in the groups whose mothers reported a high level of material hardship during pregnancy or recurring high hardship into the child's early years, and not in those without reported high hardship. Significant interactions were observed between high cord adducts and prenatal hardship on working memory scores (β = -8.07, 95% CI (-14.48, -1.66)) and between high cord adducts and recurrent material hardship (β = -9.82, 95% CI (-16.22, -3.42)). The findings add to other evidence that socioeconomic disadvantage can increase the adverse effects of toxic physical "stressors" like air pollutants

    Phthalates are a group of chemicals found in a variety of consumer products. They have anti-androgenic properties and human studies have reported associations between prenatal phthalate exposure and neuropsychological development in the offspring despite different cognitive tests, different ages and varying timing of exposure. To investigate the association between prenatal phthalate exposure and language development in children aged 20-36months. In the Odense Child Cohort, we analyzed 3rd trimester urine samples of 518 pregnant women for content of metabolites of diethyl, di-n-butyl, diisobutyl, butylbenzyl, di(2-ethylhexyl), and diisononyl phthalate, adjusted for osmolality. Language development was addressed using the Danish version of the MacArthur-Bates Communicative Development Inventories "Words and Sentences". Associations were assessed using logistic regression models comparing children below and above the 15th percentile while stratifying by sex and adjusting for maternal age and educational level. Phthalate metabolites were detectable in all samples although in lower levels than previous studies. Among boys, increased prenatal phthalate exposure was associated with lower scores in language development; odds ratios for vocabulary score below the 15th percentile with doubling in monoethyl phthalate, and summed di-(2-ethylhexyl) phthalate metabolites were respectively 1.24 (95% confidence interval: 1.05,1.46), and 1.33 (1.01,1.75). Similar associations were found for language complexity. No associations were found for girls. Our findings are notable, as adverse associations were suggested even in this low-level exposed population, with only one spot urine sample for exposure assessment and control for confounders. Lower scores in early language development are of relevance to health as this test predicts later educational success. Copyright © 2017. Published by Elsevier Inc.

    Objective To test the hypothesis that childhood maltreatment history would be associated with inadequate prenatal care utilization. Design A post-hoc analysis of a prospective cohort study of the effects of post traumatic stress disorder (PTSD) on pregnancy outcomes. Setting Recruitment took place via prenatal clinics from three academic health systems in southeast Michigan. Participants This analysis included 467 diverse, nulliparous, English-speaking adult women expecting their first infants. Methods Data were gathered from structured telephone interviews at two time points in pregnancy and from prenatal medical records. Results Contrary to our hypothesis, history of childhood maltreatment was associated with better likelihood of using adequate prenatal care. Risk for inadequate prenatal care occurred in association with the posttraumatic stress and interpersonal sensitivity that can result from maltreatment, with low alliance with the maternity care provider, and with public insurance coverage. Prior mental health treatment was associated with using adequate prenatal care. Conclusion When childhood maltreatment survivors were resilient or have used mental health treatment, they were more likely to utilize adequate prenatal care. The maternity care relationship or service delivery model (e.g., no continuity of care) as well as structural factors may adversely affect utilization among PTSD-affected survivors. Since inadequate care was associated with adverse outcomes, further studies of these modifiable factors are warranted. PMID:23772546

  9. Consumerism in prenatal diagnosis: a challenge for ethical guidelines

    2000-01-01

    The ethical guidelines for prenatal diagnosis proposed by the World Health Organisation (WHO), as well as by national regulations, only refer to paternity and gender of the fetus as unacceptable, disease-unrelated criteria for prenatal selection, as no other such parameters are at hand so far. This perspective is too narrow because research on complex genetic systems such as cognition and ageing is about to provide clinically applicable tests for genetic constituents of potentially desirable properties such as intelligence or longevity which could be misused as parameters for prenatal diagnosis. Moreover, there is an increasing number of prenatally testable genetic traits, such as heritable deafness, which are generally regarded as pathological but desired by some prospective parents and taken into account as parameters for pro-disability selection. To protect prenatal diagnosis from ethically unacceptable genetic consumerism, guidelines must be clarified as soon as possible and updated towards a worldwide restriction of prenatal genetic testing to immediately disease-determining traits. Key Words: Genetics • prenatal diagnosis • ethics • consumerism PMID:11129845

    Prenatal care coverage in Vietnam has been improving, but ethnic minority women still lag behind in receiving adequate level and type of care. This paper examines ethnic disparities in prenatal care utilization by comparing two groups of ethnic minority and majority women. We examine the roots of ethnic disparity in prenatal care utilization, focusing on how education and media exposure change health behaviours and lessen disparities. We rely on the 2002 Vietnam Demographic and Health Survey to draw our sample, predictors and the three dimensions of prenatal care, including timing of onset, frequency of visits, and type of provider. Results from multinomial-, and
