BACKGROUND: Research suggests that prenatal alcohol exposure (PAE) and Fetal Alcohol Spectrum Disorder (FASD) increases the risk of insecure caregiver-child attachment and related negative child emotional-behavioural outcomes. Research also shows positive effects of attachment-focused interventions in preventing disrupted caregiver-child attachment relationships; however, such interventions have not been specifically adapted for children with FASD. OBJECTIVES: This paper describes the implementation, challenges, and results of a community home-based attachment intervention, Circle of Security® (COS), with preschool children affected by PAE/FASD in Manitoba, Canada...

Listeria monocytogenes is an important cause of foodborne illness hospitalization, fetal loss, and death in the United States. Listeriosis incidence rate varies significantly among population subgroups with pregnant women, older persons, and the Hispanic population having increased relative risks compared with the other subpopulations. Using estimated rates of listeriosis per subpopulation based on FoodNet data from 2004 to 2009, we evaluate the expected number of cases and incidence rates of listeriosis in the US population and the pregnant women subpopulation as the demographic composition changes over time with respect to ethnicity, pregnancy status, and age distribution...

The green sea turtle (Chelonia mydas) has been a species of global concern for decades. In this study, heavy metals (mercury: Hg; Cadmium: Cd; Lead: Pb; Copper: Cu; and Zinc: Zn) were measured in blood and three egg fraction of green sea turtles nesting on the northern coast of Sea of Oman. Heavy metals concentrations in blood, yolk, albumen, and egg shell ranged between 0.16-36.78, 0.006-33.88, 0.003-4.02, and 0.002-6.85 μg/g (ww), respectively. According to the results, all heavy metals found in blood samples (n = 12) also were detected in the various parts of the eggs (n = 48)...

Hypotension commonly occurs in parturients undergoing cesarean delivery under spinal anesthesia. This leads to maternal and neonatal adverse outcomes, including maternal nausea and vomiting and fetal acidosis, and might even lead to cardiovascular collapse if not treated. Arterial dilatation and reduction in systemic vascular resistance are the major contributors to spinal-induced hypotension. Therefore, strategies aimed at expanding the intravascular volume with fluid loading or increasing venous return with lower extremities mechanical compression and lateral tilt have had limited effectiveness in the management of spinal-induced hypotension...

OBJECTIVE: Villous immaturity for gestational age is a multifactorial developmental deviation associated with unexpected placental insufficiency, fetal hypoxia and term fetal death. In our previous work we have shown that immature CD15+/CD31+/CD34+ endothelial cells were an important indicator of placental villous immaturity and chronic insufficiency. The aim of this study was to perform a comparative analysis of CD15-marked immaturity in the vessel walls between normal and pathological term placentas of clinically and structurally heterogenous groups with normal, low and high weight...

Metabolite transport is a major function for the retinal pigment epithelium (RPE) to support the neural retina. RPE dysfunction plays a significant role in retinal degenerative diseases. We have used mass spectrometry with (13)C tracers to systematically study nutrient consumption and metabolite transport in cultured human fetal RPE. LC MS/MS detected 120 metabolites in the medium from either the apical or basal side. Surprisingly, more proline is consumed than any other nutrient including glucose, taurine, lipids, vitamins, or other amino acids...

INTRODUCTION: While nausea and vomiting in early pregnancy are very common, affecting approximately 80% of pregnancies, hyperemesis gravidarum is a severe form affecting 0.3-1.0% of pregnancies. Although hyperemesis gravidarum is rarely a source of mortality, it is a significant source of morbidity. It is one of the most common indications for hospitalization in pregnancy. Beyond the maternal and fetal consequences of malnutrition, the severity of hyperemesis symptoms causes a major psychosocial burden leading to depression, anxiety, and even pregnancy termination...

Congenital microcephaly, with or without additional developmental defects, is a heterogeneous disorder resulting from impaired brain development during early fetal life. The majority of causative genetic variants identified thus far are inherited in an autosomal recessive manner and impact key cellular pathways such as mitosis, DNA damage response and repair, apoptosis and splicing. Here, we report a novel donor splice site variant in the G-patch domain and KOW motifs (GPKOW) gene (NG_021310.2:g.6126G>A, NM_015698...

Background  Monochorionic-triamniotic pregnancies are rare and fraught with complications. Case  A case of monochorionic-triamniotic triplet pregnancy complicated by twin reversed arterial perfusion (TRAP) sequence is presented. The patient declined termination or selective fetal reduction. Triplet C was acardiac. At 24 weeks, triplet B developed polyhydramnios. At 30 weeks, polyhydramnios was seen in all three amniotic sacs, but without signs of fetal hydrops and with normal Doppler velocimetry measurements in the umbilical artery, middle cerebral artery, and ductus arteriosus of triplets A and B...

Immunomodulation by mesenchymal stem cells (MSCs) is potentially important for maintaining peripheral tolerance. Preeclampsia may be due to maternal immune rejection of the genetically foreign fetus. This study aimed to investigate the biological function of human umbilical cord-derived mesenchymal stem cells (HU-MSCs) for the treatment of angiotensin receptor agonistic autoantibody (AT1-AA)-induced hypertension during pregnancy. HU-MSCs were isolated, cultured, and labeled in vitro. AT1-AA and HU-MSCs were administered to pregnant rats...

Links between the central nervous stress system and peripheral immune cells in lymphoid organs have been detailed through 50 years of intensive research. The brain can interfere with the immune system, where chronic psychological stress inhibits many functions of the immune system. On the other hand, chronic peripheral inflammation-whether mild (during aging and psychological stress) or severe (chronic inflammatory diseases)-clearly interferes with brain function, leading to disease sequelae like fatigue but also to overt psychiatric illness...

Gene silencing has immense potential in the treatment of cancer. However, enhancement of its efficiency requires the development of specifically targeted and safe carrier systems. Cationic carriers are generally limited by their immunogenicity. Hence, in this study, we report hybrid liposomes encapsulating Poly (L-lysine)-siRNA complex to silence epithelial cell adhesion molecule (EpCAM), highly expressed in epithelial cancers. The hybrid liposomes LL1 (Egg PC:DSPE-PEG, 10:0) and hybrid immunoliposomes LL2 (Egg PC:DSPE-PEG, 8:2) linked with EpCAM antibody as the targeting ligand showed an encapsulation efficiency of 70% and 86%, respectively...

OBJECTIVE: Current United States Preventative Services Task Force and other guidelines recommend low-dose aspirin for all pregnant women with pre-gestational diabetes mellitus to prevent preeclampsia and small for gestational age birth. The Maternal-Fetal Medicine Units High-Risk Aspirin trial did not show a reduction in either preeclampsia or small for gestational age birth in diabetic women. Our objective was to reassess the impact of aspirin on fetal growth in diabetic pregnancies overall and according to White classification...

INTRODUCTION: Preeclampsia is a leading cause of maternal and fetal mortality worldwide, yet its exact pathogenesis remains elusive. OBJECTIVES: This study, nested within the Vitamin D Antenatal Asthma Reduction Trial (VDAART), aimed to develop integrated omics models of preeclampsia that have utility in both prediction and in the elucidation of underlying biological mechanisms. METHODS: Metabolomic profiling was performed on first trimester plasma samples of 47 pregnant women from VDAART who subsequently developed preeclampsia and 62 controls with healthy pregnancies, using liquid-chromatography tandem mass-spectrometry...

Maternal infection during pregnancy increases the risk of neurodevelopmental conditions such as autism spectrum disorders and schizophrenia in offspring. Several previous animal studies have indicated that maternal immune activation (MIA), rather than a specific pathogen, alters fetal brain development. Among them, prenatal exposure to interleukin-6 (IL-6) has been associated with behavioral and neuropathological abnormalities, though such findings remain to be elucidated in humans. We developed a human cell-based model of MIA by exposing human induced pluripotent stem cells (hiPSCs)-derived neural aggregates to IL-6 and investigated whether luteolin-a naturally occurring flavonoid found in edible plants-could prevent MIA-induced abnormalities...

The fetal isoform A of the insulin receptor (IR-A) is frequently overexpressed in a variety of malignancies including breast cancer. IR overexpression has a recognized role in cancer progression and resistance to anticancer therapies. In particular, IR-A has a peculiar mitogenic potential and is activated not only by insulin but also by IGF-2. Previously, we identified discoidin domain receptor 1 (DDR1) as a new IR-A interacting protein. DDR1, a non-integrin collagen tyrosine kinase receptor, is overexpressed in several malignancies and plays a role in cancer progression and metastasis...
