OBJECTIVES: To evaluate the influence of examiner experience on the accuracy of sonographic weight estimation and to further analyze examiners' individual learning curves. METHODS: In this multicenter study, 4613 sonographic weight estimations performed by 18 examiners at the beginning of their ultrasound training were included. To assess the effect of experience on the accuracy of weight estimation, a multivariable mixed regression model analysis was performed, with percentage error and absolute percentage error as outcome variables and the examiner, the examiner's experience (number of examinations), birth weight, gestational age, scan-to-delivery interval, and maternal body mass index as fixed effects and the perinatal center as random intercepts...

OBJECTIVE: To evaluate the histopathological effects of smoking before, during and after pregnancy on the intervertebral disc structure of the newborns in an experimental rat model. METHODS: Seven adult female Wistar Albino rats were randomly allocated into 7 groups. Nicotine (2 mg/kg/day) was intraperitoneally introduced to these rats in 6 groups before, during and after pregnancy, while the rat in the control group received isotonic saline intraperitoneally. Fourteen newborns delivered by each rat were sacrificed at the end of 9 weeks after being breastfed for 3 weeks after birth...

OBJECTIVES: Prior studies suggest that the composition of the vaginal microbiome may positively or negatively affect susceptibility to sexually transmitted infections (STI) and bacterial vaginosis (BV). Some female hormonal contraceptive methods also appear to positively or negatively influence STI transmission and BV. Therefore changes in the vaginal microbiome that are associated with different contraceptive methods may explain, in part, effects on STI transmission and BV. STUDY DESIGN: We performed a retrospective study of 16S rRNA gene survey data of vaginal samples from a subset of participants from the Human Vaginal Microbiome Project at Virginia Commonwealth University...

INTRODUCTION: Postnatal growth restriction is considered a universal problem in extremely premature infants (EPI), and causes great concern due to the possible relationship between nutrition, sub-optimal postnatal growth, and neurodevelopment delay. OBJECTIVES: To describe the weight gain in EPI and to determine the changes in the length and head circumference (HC) at hospital discharge in survivors. PATIENTS AND METHODS: The study included 4,520 Caucasian EPI from single pregnancies and without severe malformations, born in the centres participating in the Spanish SEN1500 network (2002-2011)...

OBJECTIVES: Births to less educated women are more likely to be classified as unintended than other births. We question a common interpretation that this association reflects a lack of contraceptive knowledge or self-efficacy among less educated women. We theorize that differences in early life educational advantages structure pregnancy desires and the salience and opportunity costs of precise fertility timing. We hypothesize that net of covariates indicative of early educational disadvantage, mothers with less education are not more likely to report births as unintended compared with mothers who have attained higher levels of education before becoming mothers...

Risky, non-dependent alcohol use is prevalent in the United States, affecting 25% of adults (Centers for Disease Control and Prevention, 2014b). Massachusetts has higher rates of alcohol use and binge drinking than most states (Substance Abuse and Mental Health Services Administration, 2015). Serious physical, social, and economic consequences result. Excessive alcohol use contributes to cancer, cardiovascular disease, sleep disorders, birth defects, motor vehicle injuries, and suicide, and it complicates management of chronic illnesses (Green, McKnight-Eily, Tan, Mejia, & Denny, 2016; Laramee et al...

To evaluate the effect of endometrial injury on clinical outcomes in subfertile women with repeated implantation failures (RIF) undergoing assisted reproduction. In this prospective nonrandomized controlled trial, 103 subfertile women with RIF were included. Fifty-one underwent endometrial injury through hysteroscopy in the early follicular phase of the previous cycle and 52 underwent the standard protocol without any intervention. Live birth and miscarriage were the primary outcomes. Clinical and in vitro fertilization (IVF) cycle characteristics, were also compared between groups...

INTRODUCTION: Pituitary disorders during pregnancy are uncommon. The approach should include a close follow-up in order to reduce maternal and fetal risks associated with physiological changes during pregnancy or treatment side effects. MATERIALS AND METHODS: We report a 21-year-old woman with a thyroid-stimulating hormone-secreting pituitary macroadenoma and positive antithyroid antibodies. She was initially treated using transsphenoidal pituitary surgery. The patient relapsed 17-month post-surgery...

One of the most severe detrimental environmental factors acting during pregnancy is foetal smoke exposure. The aim of this study was to assess the effect of maternal, paternal and parental smoking during pregnancy on relative leg length in 7- to 10-year-old children. The research conducted in the years 2001-2002 included 978 term-born children, 348 boys and 630 girls, at the age of 7-10 years. Information concerning the birth weight of a child was obtained from the health records of the women. Information about the mother's and the father's smoking habits during pregnancy and about the mothers' education level was obtained from a questionnaire...

BACKGROUND: The association between prenatal exposure to maternal cigarette smoking (PEMCS) and adult cognition is debated, including if there are differences according to sex. We aimed to determine if there are associations between PEMCS and cognition in early adulthood in men and women and examine if observed associations were mediated by adolescent mental health factors that are associated with cognition, namely psychotic-like experiences (PLEs), inattention and hyperactivity, and other externalizing behaviors...

The field of neurocritical care has evolved tremendously in recent years, a development explained vastly by the advent of neurophysiological monitoring. From basic intracranial pressure measurements to brain tissue oxygenation, microdialysis, cerebral blood flow (CBF), and surface and intracortical electroencephalography (EEG), our ability to detect and control physiologic endpoints of brain function in comatose patients has grown substantially. The integration of these data gave birth to the concept of multimodality monitoring (MMM)...

STUDY QUESTION: Is blastocyst transfer safe when compared to cleavage stage embryo transfer regarding obstetric and perinatal outcomes? SUMMARY ANSWER: The clinical equipoise between blastocyst and cleavage stage embryo transfer remains as the evidence associating blastocyst transfer with some adverse perinatal outcomes is of low/very low quality. WHAT IS KNOWN ALREADY: Extended embryo culture to the blastocyst stage provides some theoretical advantages and disadvantages...

Previous studies have demonstrated the influence of changes in the age at which women give birth, and of developments in prenatal screening and diagnosis on the number of pregnancies diagnosed and terminated with chromosomal anomalies. However, we are unaware of any population studies examining pregnancy terminations after diagnosis of chromosomal anomalies that has included all aneuploidies and the influence of maternal factors. The aims of this study were to examine the association between results of prenatal tests and pregnancy termination, and the proportion of foetuses with and without chromosomal anomalies referred for invasive diagnostic tests over time...

FIAT (Factor Inhibiting ATF4-mediated Transcription) interacts with ATF4 to repress its transcriptional activity. We performed a phenotypic analysis of Fiat-deficient male mice (Fiat(-/Y)) at 8 and 16 weeks of age. Fiat(-/Y) mice appeared normal at birth and weight gain was comparable between genotypes. μCT analysis of proximal femur demonstrated 46% and 13% age-dependent increases in trabecular bone volume and thickness, respectively, in Fiat(-/Y) mice. Cortical bone measurements at the femoral midshaft revealed a significant increase in cortical thickness in older Fiat(-/Y) mice...

Hypomethylation of DNA repeats has been linked to diseases and cancer predisposition. Human studies suggest that higher blood concentrations of environmental contaminants (EC) correlate with levels of hypomethylation of DNA repeats in blood. The objective of this study was to examine the effect of in utero and/or lactational exposure to EC on the methylation of DNA repeats (LINE-1 and identifier element) in Sprague-Dawley rat pups at birth, at postnatal day (PND) 21, and in adulthood (PND78-86). From gestation day 0 to PND20, dams were exposed to a mixture "M" of polychlorinated biphenyls (PCB), pesticides, and methylmercury (MeHg), at 0...

BACKGROUND: A "less than good" experience during childbirth can affect a mother's early interaction with her child and may significantly influence a woman's emotional well-being. In this study, we focus on clients who experienced midwifery care provided during childbirth as "less than good" care. The aim of this study was to understand the relationship between client-related factors and the experience of midwifery care during childbirth to improve this care. METHODS: This study was part of the "DELIVER study" where mothers report on the care they received...
