Background: Most of the newborn deaths in developing countries occur at home. Up to two-thirds of these deaths would have been prevented if mothers and newborns had received known and effective interventions. The objective of this study is to determine newborn-care practices and health-seeking behavior in rural Eastern Ethiopia. Methods: A community-based cross-sectional study was conducted in Adadle district, Ethiopian Somali Regional State. A multi-stage random sampling technique was applied...

BACKGROUND: Small ubiquitin-like modifiers (SUMOs) conjugate to proteins post-translationally, thereby affecting target localization, activity and stability. Functional SUMO family members identified in the human placenta include SUMO-1 to SUMO-3, which are elevated in pre-eclampsia. Whether the fourth isoform, SUMO-4, plays a role in placental development and function remains unknown. OBJECTIVES: We tested the hypothesis that SUMO-4 is expressed in the human placenta and demonstrates altered SUMOylation in pre-eclamptic pregnancies...

BACKGROUND: The accuracy of common ultrasound parameters for the estimation of gestational age (GA) decreases as pregnancy advances in age. Hence, there is need to explore other parameters that may complement the established fetal biometric parameters in predicting GA in late pregnancy. AIM: The aim of this study is to determine the relationship between the sonographic placental thickness (PT) and GA in the second and third trimesters. SUBJECTS AND METHODS: A cross-sectional study of 627 normal pregnant women with GA between 14 and 40 weeks was conducted at the University of Nigeria Teaching Hospital Ituku-Ozalla, Enugu from May 2013 to February 2014 by sonography...

This study aimed to measure the physiological changes in the combined utero-placental thickness (CUPT) during the course of normal pregnancy in Mangalarga Marchador mares. Transrectal B-mode ultrasonography was used to measure CUPT in 42 pregnant mares with a mean age, 8.7 (±3.5 years). CUPT was measured every month from 150 days of gestation until delivery. CUPT was expressed as an average of three measurements of the distance (mm) between the middle part of the uterine artery and the allantoic fluid. A General Linear Model was used to evaluate the major effects of the chronological age and stage of gestation on CUPT in mares...

BACKGROUND: Polycystic ovary syndrome (PCOS) is the most common endocrinopathy affecting reproductive-aged women. The pathophysiology of this syndrome is still not completely understood but recent evidence suggests that the intra-uterine environment may be a key factor in the pathogenesis of PCOS, in particular, hyperexposure of the foetus to androgens. High concentrations of maternal serum testosterone during pregnancy have been shown to influence behaviour during childhood, the prevalence of autism disorders and anti-Mullerian hormone (AMH) concentrations in adolescence...

Reproductive failure in humans is a very important social and economic problem, because nowadays women decide to conceive later in life and delay motherhood. Unfortunately, with increasing age they have less chance for natural fertilization and maintenance of pregnancy. Many of them need assisted reproductive technology. Approximately 10% of women after in vitro fertilization-embryo transfers experience recurrent implantation failure (RIF). Multiple factors may contribute to RIF, including oocyte and sperm quality, parental chromosomal anomalies, genetic or metabolic abnormalities of the embryo, poor uterine receptivity, immunological disturbances in the implantation site, and some gynecologic pathologies such as endometriosis, uterine fibroids, hydrosalpinx and endometrial polyps...

Lead in maternal blood can cross the placenta and result in elevated blood lead levels in newborns, potentially producing negative effects on neurocognitive function, particularly if combined with childhood lead exposure. Little research exists, however, into the burden of elevated blood lead levels in newborns, or the places and populations in which elevated lead levels are observed in newborns, particularly in rural settings. Using ~2300 dried bloods spots collected within 1-3 days of birth among Iowa newborns, linked with the area of mother's residence at the time of birth, we examine the spatial patterns of elevated (>5 μg/dL) blood lead levels and the ecological-level predictors of elevated blood lead levels...

Maternal obesity is a major risk factor for pregnancy complications, causing inflammatory cytokine release in the placenta, including interleukin-1β (IL-1β), IL-6, and IL-8. Pregnant women with obesity develop accelerated systemic and placental inflammation with elevated circulating advanced glycation end products (AGEs). IL-1β is a pivotal inflammatory cytokine associated with obesity and pregnancy complications, and its production is regulated by NLR family pyrin domain-containing 3 (NLRP3) inflammasomes...

INTRODUCTION: Hypertensive Disorders of Pregnancy (HDP) are one of the most widespread complications of pregnancy that affects both mother and foetus. It has been observed that in Preeclampsia, the release of soluble angiogenic factors from the ischemic placenta into maternal plasma plays a crucial role in the pathogenesis. AIM: To assess the plasma Soluble Endoglin (sEng) and Transforming Growth Factor (TGF-β1) levels in various types of HDP and to correlate the levels of these markers with the pregnancy outcome...

Small for gestational age infants have greater risk of developing metabolic diseases in adult life. It has been suggested that low birth weight may result from glucocorticoid excess in utero, a key mechanism in fetal programming. The placental enzyme 11-beta hydroxysteroid dehydrogenase type 2 (11β-HSD2, HSD11B2 gene) acts as a barrier protecting the fetus from maternal corticosteroid deleterious effects. Low placental 11β-HSD2 transcription and activity have been associated with low birth weight, yet the mechanism regulating its protein expression is not fully understood...

BACKGROUND: The developmentally important DLK1-DIO3 imprinted domain on human chromosome 14 is regulated by two differentially methylated regions(DMRs), the IG-DMR and the MEG3 DMR. OBJECTIVES: The aim was to determine the natural variation in DNA methylation at these DMRs in human placentas, and to determine its link to gene expression levels at the domain. Second, to explore whether the domain's methylation and gene expression correlate with pre- and early-postnatal growth of the conceptus...

Abnormally invasive placentation is becoming more common with a recent increase in cesarean sections and maternal age, among other risk factors. Ultrasonography is the first line-imaging, but it can be difficult to diagnose when limiting factors are present. Failure to recognize this serious placental abnormality precludes us from making the appropriate plan for the delivery and consequently can lead to fatal results. In this report, we present a case in which magnetic resonance imaging was used to diagnose posterior placenta increta missed by multiple sonographic examinations in a patient with previous myomectomies, and we also include a review of the literature on this topic...

Gestational diabetes mellitus (GDM) is associated with obesity in childhood. This suggests that consequences of in utero exposure to maternal hyperglycemia extend beyond the fetal development, possibly through epigenetic programming. The aims of this study were to assess whether placental DNA methylation (DNAm) marks were associated with maternal GDM status and to offspring body composition at 5 years old in a prospective birth cohort. DNAm levels were measured in the fetal side of the placenta in 66 samples (24 from GDM mothers) using bisDNA-pyrosequencing...

Trophoblast cells are the first embryonic lineage to differentiate during human development, and are needed to sustain fetal life through their role in constructing a placenta. As the fetus grows, the trophoblast rapidly expands and further differentiates to produce an extravillous subtype that invades the maternal tissues. Some of the extravillous trophoblast cells find their way into the reproductive tract, and can be safely captured by noninvasive collection from the endocervical canal, similarly to a Pap smear...
