STUDY QUESTION: Can we separate embryos cultured under either 7% or 20% oxygen atmospheres by measuring their metabolic heterogeneity? SUMMARY ANSWER: Metabolic heterogeneity and changes in metabolic profiles in morula exposed to two different oxygen concentrations were not detectable using traditional fluorophore and two-channel autofluorescence but were detectable using hyperspectral microscopy. WHAT IS KNOWN ALREADY: Increased genetic and morphological blastomere heterogeneity is associated with compromised developmental competence of embryos and currently forms the basis for embryo scoring within the clinic...

BACKGROUND AND PURPOSE: With the popularization of a two-child policy in China, the number of pregnant women of advanced maternal age will increase steadily. We aimed to assess the association between pre-pregnancy body mass index (BMI) and weight gain in the first and second trimester and the risk of gestational diabetes (GDM) in the advanced maternal age group and control group defined as maternal age of 20-35 years. RESULTS: The risk of GDM for obesity before pregnancy was 2...

Context: Low vitamin B12 (B12) during pregnancy is associated with higher maternal obesity, insulin resistance(IR) and gestational diabetes(GDM). B12 is a key co-factor in 1-carbon metabolism. Objective: We hypothesize that B12 plays a role in epigenetic regulation by altering circulating miRNAs(miRs) during adipocyte differentiation and results in an adverse metabolic phenotype. Design, settings and main-outcome measure: Human pre-adipocyte cell-line(Chub-S7) were differentiated in various B12 concentrations: Control(500nM), LowB12(0...

The endocrine disrupting chemical bisphenol A (BPA) increases adipose tissue mass in vivo and promotes adipogenesis in vitro. However, mechanisms explaining BPA's obesogenic effect remain unknown. We investigated the effects of gestational BPA and its analogue, bisphenol S (BPS), exposure on the adipogenic differentiation ability of fetal preadipocytes and the role of endoplasmic reticulum stress in regulating this process. Pregnant sheep (n=7-8/group) mated to the same male were exposed to BPA or BPS from days 30 to 100 of gestation, and pregnancies terminated 20 days later...

Context: High homocysteine concentrations are associated with maternal pregnancy complications and low birth weight, jaundice and cerebrovascular accidents in neonates. Thyroid hormone may interfere with homocysteine metabolism via stimulation of vitamin B12- and folate-dependent processes and via effects on enzymes of the re-methylation pathway. Objective: Investigating the associations of maternal and neonatal thyroid function with homocysteine during pregnancy and after delivery, respectively...

Context: Women with polycystic ovary syndrome (PCOS) commonly have intrinsic insulin resistance and are recommended to undergo an oral glucose tolerance test (OGTT) for diabetes screening. However, the effect of preconception impaired glucose tolerance (IGT) on pregnancy is still unclear. Objective: To prospectively assess the effect of preconception IGT on pregnancy outcomes. Design, Setting, Patients, Intervention(s) and Main Outcome Measure(s): This was a secondary analysis of a multicenter randomized trial in 1508 women with PCOS comparing live birth and obstetric complications between fresh and frozen embryo transfer...

Calreticulin (CRT), a molecular chaperone in the endoplasmic reticulum (ER), plays a variety of roles in cell growth, differentiation, apoptosis, immunity, and cancer biology. It has been reported that CRT is expressed in the human placenta, although its function in placental development is poorly understood. Appropriate invasion of extravillous trophoblasts (EVTs) into the maternal decidua is necessary for successful pregnancy. The objective of the present study was to investigate the expression and functional role of CRT in EVTs by utilizing the human EVT cell line HTR8/SVneo, in which CRT gene expression was knocked down...

Context: Resistance to thyroid hormone beta (RTHβ) is an autosomal dominant disorder characterized by reduced sensitivity of target tissues to thyroid hormones (TH). Individuals with RTHβ have high TH levels usually due to mutations in the TH receptor beta (THRB) gene. The management of RTHβ during pregnancy is challenging as wild-type (WT) fetuses born to RTHβ mothers have low birth weight and suppressed postnatal TSH, due to intrauterine exposure to excess TH. Objective: To determine birth weight and postnatal TSH of WT fetuses carried by mothers with RTHβ whose fT4 levels were maintained below 20% the upper limit of normal (ULN)...

Successful pregnancy relies on dynamic control of cell signaling in order to achieve uterine receptivity and the necessary biological changes required for endometrial decidualization, embryo implantation, and fetal development. Glucocorticoids are master regulators of intracellular signaling and can directly regulate embryo implantation and endometrial remodeling during murine pregnancy. In immortalized human uterine cells, we have shown that glucocorticoids and estradiol co-regulate thousands of genes. Recently, glucocorticoids and estradiol were shown to co-regulate the expression of Left-right determination factor 1 (LEFTY1), previously implicated in the regulation of decidualization...

PURPOSE OF REVIEW: Quality contraceptive counseling has been identified as a potential means to reduce unintended pregnancy and to increase contraceptive continuation and satisfaction. Past approaches that focused on autonomous decision making and directive counseling have not been shown to meet these goals consistently. Women's health organizations globally are calling for improved counseling through more thorough discussion of side-effects and bleeding changes, and renewed focus on shared decision making and patient-centered care...

Domestic violence is a global public health issue. Midwives are ideally placed to screen for, and respond to, disclosure of domestic violence. Qualified midwives and midwifery students report a lack of preparedness and low levels of confidence in working with women who disclose domestic violence. This paper reports the findings from an education intervention designed to increase midwifery students' confidence in working with pregnant women who disclose domestic violence. An authentic practice video and associated interactive workshop was developed to bring the 'woman' into the classroom and to provide role-modelling of exemplary midwifery practice in screening for and responding to disclosure of domestic violence...

During pregnancy, prolactin (PRL) is a neuro-immuno-cytokine that contributes actively to the crosstalk between the immune and endocrine systems and, thus, to the creation of an immune-privileged milieu. This work aims to analyze the capacity of PRL to modulate the synthesis and secretion of pro-inflammatory markers associated with labor. Studies were conducted using human fetal membranes at term mounted in a model of two independent chambers. The choriodecidual region was stimulated with 500-ng/mL lipopolysaccharide (LPS), and the amnion and choriodecidual region were co-simulated with different concentrations of PRL that can arise during pregnancy: 250, 500, 1000, and 4000ng/mL...

The high neonatal and maternal morbidity and mortality associated with the extremes of birth weight is referred to as the obstetric dilemma. Pre-eclampsia and other conditions that lead to low birth weight are considered as the Great Obstetrical Syndromes (GOS). At the other extreme is high birth weight resulting in obstructed labour. Fetal weight largely depends on placental function and defective placentation is a common feature of the GOS. There is evidence that the local uterine immune system (KIR and HLA-C) regulates placentation, with racial differences noted...

BACKGROUND: Sex-specific associations have been reported between phthalates, bisphenol A (BPA), and child behavior. No data on large study populations are available for other phenols with possible endocrine-disrupting properties. OBJECTIVES: We aimed to study associations between prenatal exposure to phthalates and several phenols on behavior among male infants. METHODS: We quantified 11 phthalate metabolites and nine phenols (four parabens, benzophenone-3, BPA, two dichlorophenols, triclosan) in spot urine samples collected during pregnancy among EDEN cohort mothers who delivered a boy...

BACKGROUND: Postpartum contraception is especially important for women who use alcohol and other substances, given the risk of possible rapid repeat pregnancy and prenatal substance exposure. However, little is known about postpartum contraceptive use among women with substance use histories. OBJECTIVE: To characterize postpartum contraceptive initiation, 24-month continuation, and rapid repeat pregnancy among women who used substances during pregnancy. METHODS: This is a secondary analysis of 161 pregnant women who enrolled in a randomized clinical trial to treat substance use in pregnancy and completed at least one follow-up assessment...
