INTRODUCTION: Evidence from animal models suggests that prenatal exposure to bisphenol A (BPA), a ubiquitous endocrine-disrupting chemical, is associated with adverse reproductive outcomes in females. Exposure during early gestation, a critical period for reproductive development, is of particular concern. Anogenital distance (AGD) is a sensitive biomarker of the fetal hormonal milieu and a measure of reproductive toxicity in animal models. In some studies, the daughters of BPA-exposed dams have shorter AGD than controls...

A deep dive into microglia form and function reveals startling regional heterogeneity in number, morphology, activity, and transcriptomics in nuclei relevant to motor control and motivation (De Biase et al., 2017). Differences appear 2 weeks after birth, and depletion and recolonization in adulthood recapitulate the original phenotype, implicating local environment as mediators of microglial phenotype.

BACKGROUND: Preterm birth is known to constitute the major risk factor for development of germinal matrix-intraventricular hemorrhage (GM-IVH). Head position may affect cerebral hemodynamics and thus may be involved indirectly in development of GM-IVH. Turning the head toward one side may functionally occlude jugular venous drainage on the ipsilateral side while increasing intracranial pressure and cerebral blood volume. Thus, it has been suggested that cerebral venous pressure is reduced and hydrostatic brain drainage improved if the patient is in supine midline position with the bed tilted 30°...

BACKGROUND: There is no apparent consensus on obstetric management, i.e., induction of labor or expectant management of women with suspected large-for-gestational-age (LGA)-fetuses. METHODS AND FINDINGS: To further examine the subject, a nationwide population-based cohort study from the Swedish Medical Birth Register in nulliparous non-diabetic women with singleton, vertex LGA (>90th centile) births, 1992-2013, was performed. Delivery of a live-born LGA infant induced at 38 completed weeks of gestation in non-preeclamptic pregnancies, was compared to those of expectant management, with delivery at 39, 40, 41, or 42 completed weeks of gestation and beyond, either by labor induction or via spontaneous labor...

BACKGROUND: The triggering of thyroid autoimmunity in the genetically susceptible remains a conundrum. Environmental exposures during gestation and/or early postnatally have proponents, as suggested in diabetes mellitus, with a higher incidence of births during spring and summer. Whether the development of autoimmune hypothyroidism (AIT) is influenced by month or season of birth is less clear. METHOD: Nationwide cohort study of 111,565 individuals diagnosed with AIT and four euthyroid controls per case, matched according to age and sex, were identified from Danish health registers...

INTRODUCTION: The long allele of the DRD4 gene can confer different behavioral and emotional phenotypes depending upon environmental exposure, although the physiological changes underlying these phenotypes are not fully known. We sought to extend this work by assessing the interaction of the DRD4 gene and exposure to perinatal adversity (indexed by extremely low birth weight [ELBW]) on resting respiratory sinus arrhythmia (RSA), a neurophysiological measure of emotion regulation, in adulthood...

The size, support, and health of udders limit the productive life of beef cows, especially those with background, because, in general, such cows have a reputation for problems with udders. Genomic association studies of bovine udder traits have been conducted in dairy cattle and recently in Continental European beef breeds but not in cows with background. The objective of this study was to determine associations of SNP and udder support scores, teat length, and teat diameter in half (Nellore), half (Angus) cows...

AIM: To explore attitudes to safe-induced abortion among pregnant women in Iran. BACKGROUND: In Islamic teachings abortion is generally forbidden. However in specific circumstances abortion may be permitted and currently, in Iran, the law allows termination of pregnancy only if three specialist physicians confirm that the pregnancy outcome may be harmful for the mother during pregnancy or after birth. DESIGN: Pilot, descriptive survey. METHODS: A 15-item structured questionnaire focusing on attitudes to safe-induced abortion was developed and pilot tested...

REVIEW
William E Benitz, Shazia Bhombal
Over the last four decades, non-steroidal anti-inflammatory drugs have been widely used to induce closure of the patent ductus arteriosus (PDA) in preterm infants. Evidence to support this practice is lacking, despite performance of >50 randomized trials. The credibility of those trials may have been compromised by high rates of open treatment in controls, era of study prior to advent of modern practices, or inclusion of insufficient numbers of very immature infants. Meta-analyses show little impact of those factors on main conclusions...

The rhesus macaque population at Cayo Santiago increases annually and is in urgent need of control. In-depth assessments of the colony's population genetic and pedigree structures provide a starting point for improving the colony's long-term management program. We evaluated the degree of genetic variation and coefficients of inbreeding and kinship of the Cayo Santiago colony by using pedigree and short tandem repeat (STR) data from 4738 rhesus macaques, which represent 7 extant social groups and a group of migrant males...

GOALS: To examine the impact of maternal hepatitis B virus infection on pregnancy outcomes. BACKGROUND: Studies regarding hepatitis B virus infection and pregnancy outcomes are limited with inconsistent results, and none of them have evaluated the effect of maternal viral load in pregnancy on pregnancy outcomes. STUDY: A hospital-based case-control study was conducted. In total, 1728 hepatitis B surface antigen (HBsAg)-positive women who delivered consecutively at Wuhan Women and Children Medical and Healthcare Center, Wuhan, China, from June 2008 to May 2015, were compared with 1497 HBsAg-negative women giving birth in the same hospital during the same period who were randomly identified and selected from the computerized medical record database in parallel...

We evaluated the association between maternal occupation and the risk of neural tube defects (NTDs) in offspring. Data for 491 nonsyndromic cases were obtained from the Texas Birth Defects Registry for deliveries between 1999 and 2009. We randomly selected 2,291 controls among all live births in Texas during this time. Maternal occupations were classified using automated software and manual assignment. Multivariable logistic regression analyses were used to examine the relationship between maternal occupation and risk for any NTD, adjusting for maternal race/ethnicity, any diabetes, and maternal body mass index...

BACKGROUND: Pain is a common feature of childhood and adolescence around the world, and for many young people, that pain is chronic. The World Health Organization (WHO) guidelines for pharmacological treatments for children's persisting pain acknowledge that pain in children is a major public health concern of high significance in most parts of the world. Views on children's pain have changed over time and relief of pain is now seen as important. In the past, pain was largely dismissed and was frequently left untreated, and it was assumed that children quickly forgot about painful experiences...

Infectious diarrhoea is a worldwide problem in newborns. Optimal bacterial colonisation may enhance gut maturation and protect against pathogenic bacteria after birth. We hypothesised that lactic acid bacteria (LAB) administration prevents pathogen-induced diarrhoea in formula-fed newborns. Newborn caesarean-delivered, colostrum-deprived term piglets on parenteral nutrition for the first 15 h, were used as models for sensitive newborn infants. A commercially available probiotic strain, Lactobacillus paracasei F19 (LAP, 2·6×108 colony-forming units (CFU)/kg per d) and a novel LAB isolate, Pediococcus pentosaceus (PEP, 1·3×1010 CFU/kg per d), were administered for 5 d with or without inoculation of the porcine pathogen, Escherichia coli F18 (F18, 1010 CFU/d)...
