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

Social anxiety is the most common anxiety disorder among youth; theoretical and empirical work suggest specific parenting behaviors may be relevant. However, findings are inconsistent, particularly in terms of maternal as compared to paternal effects. In the current study, we evaluated the indirect effects of perceived psychological control on the relation between anxious rearing behaviors and child social anxiety among 112 community-recruited girls (ages 12-15 years). In addition to self-report, adolescent participants completed a laboratory-based social stress task...

BACKGROUND: Prenatal phthalate exposure has been associated with behavioral problems and lower performance on measures of cognitive ability in children. However, the potential effect of phthalate exposure during the sensitive preconception period is unknown. OBJECTIVES: To estimate the association of maternal and paternal preconception urinary phthalate metabolite concentrations with child behavior and evaluate potential modification by child sex. METHODS: We used data from 166 children (111 singletons, 26 pairs of twins, and 1 set of triplets) born to 134 mothers and 100 fathers participating in a prospective preconception cohort study of subfertile couples from the Massachusetts General Hospital Fertility Center...

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

OBJECTIVES: Advancing paternal age has been associated with several neuropsychiatric disorders in children. However, there is limited understanding of this association with obsessive compulsive disorder (OCD) and Tourette syndrome/chronic tic disorder (TS/CT) with inconsistent findings. We examined the association between parental age and offspring OCD and TS/CT. METHODS: This nested case-control study used the Finnish Hospital Discharge Register (FHDR) to identify 1358 individuals with OCD and 1195 with TS/CT, born from 1991 to 2009 and diagnosed by 2010...

During pregnancy, tryptophan (Trp) is required for several purposes, and Trp metabolism varies over time in the mother and fetus. Increased oxidative stress (OS) with high metabolic, energy and oxygen demands during normal pregnancy or in pregnancy-associated disorders has been reported. Taking the antioxidant properties of Trp and its metabolites into consideration, we made four hypotheses. First, the use of Trp and its metabolites is optional based on their antioxidant properties during pregnancy. Second, dynamic Trp metabolism is an accommodation mechanism in response to OS...

Vitamin D deficiency in pregnancy may be associated with increased offspring adiposity, but evidence from human studies is inconclusive. We examined associations between prenatal vitamin D intake, 25-hydroxyvitamin D (25(OH)D) in cord blood, and offspring size and body composition at birth and 5 months. Participants included 605 mother-offspring dyads from the Healthy Start study, an ongoing, pre-birth prospective cohort study in Denver, Colorado, USA. Prenatal vitamin D intake was assessed with diet recalls and questionnaires, and offspring body composition was measured via air displacement plethysmography at birth and 5 months...

Chikungunya virus is capable of affecting the nervous system of children and adults. We describe a case of sepsis and encephalitis triggered by this agent in a newborn whose mother developed symptoms of acute infection two days before delivery. Consequently, the infant had severe encephalitis that evolved with postnatal-onset microcephaly, bilateral optic atrophy, epilepsy and cerebral palsy.

OBJECTIVES: Breast-feeding may protect against infections, but its optimal duration remains controversial. We aimed to study the association of the duration of full and any breast-feeding with infections the first 18 months of life. METHODS: The Norwegian Mother and Child study (MoBa) is a prospective birth cohort which recruited expecting mothers giving birth from 2000 to 2009. We analyzed data from the full cohort (n = 70,511) and sibling sets (n = 21,220) with parental report of breast-feeding and infections...

In this study, we describe two patients with a recombinant chromosome secondary to a maternal intrachromosomal insertion. Patient 1 was a girl with dup(6)(p22.3p25.3). Patient 2 was a boy with dup(2)(q24.2q32.1). Both familial rearrangements were characterized by means of GTG-bands, fluorescence in-situ hybridization, and comparative genomic hybridization microarray analyses. Patient 1 had an ∼23 Mb gain that involved the bands 6p22.3-6p25.3. Patient 2 had an ∼23 Mb gain (cytobands 2q24.2-2q32.1) and a further ∼1...

BACKGROUND: Given the increasing proportion of United States hospitals that are for-profit, we examined whether women who give birth in for-profit hospitals are more likely to have cesareans than women who give birth in not-for-profit hospitals. We hypothesized that cesareans are more likely to occur in for-profit hospitals because of the organizational emphasis on short-term financial indicators, including payment of shareholder dividends. METHODS: We used logistic regression and difference of means tests to analyze data from the Listening to Mothers III survey of women who gave birth in the United States in 2011 and 2012...

Images of four qualities of Mangoes and Guavas are evaluated for colour and textural features to characterize and classify them, and to model the fruit appearance grading. The paper discusses three approaches to identify most discriminating texture features of both the fruits. In the first approach, fruit's colour and texture features are selected using Mahalanobis distance. A total of 20 colour features and 40 textural features are extracted for analysis. Using Mahalanobis distance and feature inter-correlation analyses, one best colour features [mean of a* (L*a*b* colour space) and two textural features [energy a*, contrast of H*]are selected as features for guava while two best colour features [R std, H std] and one textural features [energy b*]are selected as features for Mangoes with the highest discriminate power...
