Folate deficiency during pregnancy has been related to low birth weight, preterm (PT) birth and other health risks in the offspring; however, it is unknown whether prematurity is related to low folate transport through the placenta due to altered expression of specific folate transporters. We determined placental expression (mRNA and protein concentrations by RT-qPCR and WB respectively) of specific folate transporters: RFC, PCFT/HCP1 and FOLR1 in chorionic (fetal) and basal (maternal) plates of placentas of PT pregnancies (PT, 32-36 weeks, n = 51)...

Pertussis and influenza infections can result in severe disease in infants. The diphtheria, tetanus, acellular pertussis (DTaP) vaccine is recommended for infants beginning at age 2 months, and influenza vaccine is recommended for infants aged ≥6 months. Vaccination of pregnant women induces the production of antibodies that are transferred across the placenta to the fetus and provide passive protection until infants are old enough to receive DTaP and influenza vaccines (1-3). To protect young infants before they are age-eligible for vaccination, the Advisory Committee on Immunization Practices (ACIP) has recommended since 2004 that all women who are or will be pregnant during influenza season receive inactivated influenza vaccine (1), and since 2013 that all pregnant women receive the tetanus, diphtheria, acellular pertussis (Tdap) vaccine (3)...

Invasive placentation and cancer development shares many similar molecular and epigenetic pathways. Paternally expressed, growth promoting genes (SNRPN, PEG10 and MEST) which are known to play crucial role in tumorogenesis, are not well studied during placentation. This study reports for the first time of the impact of gestational-age, pathological conditions and folic acid supplementation on dynamic nature of DNA and histone methylation present at their differentially methylated regions (DMRs). Here, we reported the association between low DNA methylation/H3K27me3 and higher expression of SNRPN, PEG10 and MEST in highly proliferating normal early gestational placenta...

Autophagy, a cell-survival process responsible for degradation of protein aggregates and damaged organelles, is increasingly recognized as another mechanism essential for human placentation. A substantial body of experiments suggests inflammation and oxidative stress as the underlying stimuli for altered placental autophagy, giving rise to placenta dysfunction and pregnancy pathologies. Here, the hypothesis is tested whether or not pro-inflammatory cytokines interleukin (IL)-6 and tumor necrosis factor (TNF)-α are able to influence the expression profile of autophagy genes in human first-trimester villous placenta...

Endometrial ablation offers symptomatic relief for menorrhagia. Pregnancy after ablation is rare but is often complicated due to pregnancy loss, growth restriction, preterm premature rupture of membranes, preterm delivery, and morbidly adherent placentation, a dangerous complication that can result in hemorrhage, intensive care unit admission, and cesarean hysterectomy. We report a case of pregnancy conceived contemporaneously with endometrial ablation and tubal occlusion. Diagnosis of pregnancy was delayed due to low suspicion...

Fetal exposure to drugs cannot be readily estimated from single time point cord blood sampling at the time of delivery. Therefore, we developed a physiologically-based pharmacokinetic (PBPK) model to estimate fetal drug exposure throughout pregnancy. Here we report verification of this novel maternal-fetal physiologically-based pharmacokinetic (m-f-PBPK) model for drugs that passively diffuse across the placenta and are not metabolized/transported there. Our recently built m-f-PBPK model was populated with gestational age-dependent changes in maternal drug disposition and maternal-fetal physiology...

BACKGROUND: Failure of physiologic transformation of spiral arteries has been reported in preeclampsia, fetal growth restriction, fetal death, and spontaneous preterm labor with intact or ruptured membranes. Spiral arteries with failure of physiologic transformation are prone to develop atherosclerotic-like lesions of atherosis. There are striking parallels between preeclampsia and atherosclerotic disease, and between lesions of atherosis and atherosclerosis. Endothelial activation, identified by intercellular adhesion molecule-1 (ICAM-1) expression, is present in atherosclerotic-like lesions of heart transplantation, and is considered a manifestation of rejection...

BACKGROUND: Autism spectrum disorders (ASD) are increasingly prevalent neurodevelopmental disorders that are behaviorally diagnosed in early childhood. Most ASD cases likely arise from a complex mixture of genetic and environmental factors, an interface where the epigenetic marks of DNA methylation may be useful as risk biomarkers. The placenta is a potentially useful surrogate tissue characterized by a methylation pattern of partially methylated domains (PMDs) and highly methylated domains (HMDs) reflective of methylation patterns observed in the early embryo...

A farm-level stochastic model was used to estimate costs of 7 common clinical diseases in the United States: mastitis, lameness, metritis, retained placenta, left-displaced abomasum, ketosis, and hypocalcemia. The total disease costs were divided into 7 categories: veterinary and treatment, producer labor, milk loss, discarded milk, culling cost, extended days open, and on-farm death. A Monte Carlo simulation with 5,000 iterations was applied to the model to account for inherent system variation. Four types of market prices (milk, feed, slaughter, and replacement cow) and 3 herd-performance factors (rolling herd average, product of heat detection rate and conception rate, and age at first calving) were modeled stochastically...

INTRODUCTION: Offspring exposed to preeclampsia (PE) show an increased risk of cardiovascular disease in adulthood. We hypothesize that this is mediated by a disturbed vascular development of the placenta, umbilical cord and fetus. Therefore, we investigated associations between early-onset PE (EOPE), late-onset PE (LOPE) and features of placental and newborn vascular health. METHODS: We performed a nested case-control study in The Rotterdam Periconceptional Cohort, including 30 PE pregnancies (15 EOPE, 15 LOPE) and 218 control pregnancies (164 uncomplicated controls, 54 complicated controls including 28 fetal growth restriction, 26 preterm birth) and assessed macroscopic and histomorphometric outcomes of the placenta and umbilical cord...

INTRODUCTION: Maternal vascular malperfusion (MVM) lesions represent hypoxic-ischemic damage to the placenta, and they are associated with adverse pregnancy outcomes. Women with gestational diabetes (GDM) are at increased risk for pregnancy complications, so we set out to characterize the prevalence and clinical correlates of MVM lesions in this cohort. METHODS: This was a retrospective cohort study of 1187/1374 (86.4%) women with GDM delivered between 2009 and 2012 who had placental pathology available...

BACKGROUND: Endometriosis, which occurs in approximately 10% of women of reproductive age, is defined as the presence of endometrial tissue outside the uterus. Women with endometriosis are more likely to have difficulty conceiving and tend to receive infertility treatment, including assisted reproductive technology (ART) therapy. There has not yet been a prospective cohort study examining the effects of endometriosis on pregnancy outcome in pregnant Japanese women. METHODOLOGY: This was a prospective cohort study of the incidence of obstetrical complications in women with endometriosis using data of the Japan Environment & Children's Study (JECS)...
