    Full Text Available Background0 : Human chimerism is rare and usually uncovered through investigations of ambiguous genitalia or blood grouping or prenatal diagnosis. Most of the publications on placental chimerism are mainly case reports. There is no systematic search with sensitive techniques for placental chimerism in human. Aim0 : This study was aimed to asses placental chimerism through two sensitive molecular techniques i.e., interphase fluorescent in situ hybridization and quantitative fluorescent PCR. Material and methods0 : Placental chimerism was analyzed using X & Y dual color fluorescent in-situ hybridization onto 154 placentae from natural conceptions, obtained at termination of pregnancy between 7 to 16 weeks of gestation. Results0 : Three cases of placental sex chromosome chimerism were observed (1.95%. Exclusion of maternal contamination and diagnosis was confirmed later by quantitative fluorescent PCR. Conclusion0 : This finding indicates that placental chimerism in early human pregnancy is not rare.

    Full Text Available Our objective was to determine the expression of the elements of the Lin28/Let-7 system, and related microRNAs (miRNAs, in early stages of human placentation and ectopic pregnancy, as a means to assess the potential role of this molecular hub in the pathogenesis of ectopic gestation. Seventeen patients suffering from tubal ectopic pregnancy (cases and forty-three women with normal on-going gestation that desired voluntary termination of pregnancy (VTOP; controls were recruited for the study. Embryonic tissues were subjected to RNA extraction and quantitative PCR analyses for LIN28B, Let-7a, miR-132, miR-145 and mir-323-3p were performed. Our results demonstrate that the expression of LIN28B mRNA was barely detectable in embryonic tissue from early stages of gestation and sharply increased thereafter to plateau between gestational weeks 7-9. In contrast, expression levels of Let-7, mir-132 and mir-145 were high in embryonic tissue from early gestations (≤ 6-weeks and abruptly declined thereafter, especially for Let-7. Opposite trends were detected for mir-323-3p. Embryonic expression of LIN28B mRNA was higher in early stages (≤ 6-weeks of ectopic pregnancy than in normal gestation. In contrast, Let-7a expression was significantly lower in early ectopic pregnancies, while miR-132 and miR-145 levels were not altered. Expression of mir-323-3p was also suppressed in ectopic embryonic tissue. We are the first to document reciprocal changes in the expression profiles of the gene encoding the RNA-binding protein, LIN28B, and the related miRNAs, Let-7a, mir-132 and mir-145, in early stages of human placentation. This finding suggests the potential involvement of LIN28B/Let-7 (deregulated pathways in the pathophysiology of ectopic pregnancy in humans.

    Preeclampsia, a cardiovascular disorder of late pregnancy, is characterized as a low-renin hypertensive state relative to normotensive pregnancy. Because other nonpregnant low-renin hypertensive disorders often exhibit and are occasionally dependent on elevated arginine vasopressin (AVP) secretion, we hypothesized a possible use for plasma AVP measurements in the prediction of preeclampsia. Copeptin is an inert prosegment of AVP that is secreted in a 1:1 molar ratio and exhibits a substantially longer biological half-life compared with AVP, rendering it a clinically useful biomarker of AVP secretion. Copeptin was measured throughout pregnancy in maternal plasma from preeclamptic and control women. Maternal plasma copeptin was significantly higher throughout preeclamptic pregnancies versus control pregnancies. While controlling for clinically significant confounders (age, body mass index, chronic essential hypertension, twin gestation, diabetes mellitus, and history of preeclampsia) using multivariate regression, the association of higher copeptin concentration and the development of preeclampsia remained significant. Receiver operating characteristic analyses reveal that as early as the sixth week of gestation, elevated maternal plasma copeptin concentration is a highly significant predictor of preeclampsia throughout pregnancy. Finally, chronic infusion of AVP during pregnancy (24 ng per hour) is sufficient to phenocopy preeclampsia in C57BL/6J mice, causing pregnancy-specific hypertension, renal glomerular endotheliosis, proteinuria, and intrauterine growth restriction. These data implicate AVP release as a novel predictive biomarker for preeclampsia very early in pregnancy, identify chronic AVP infusion as a novel and clinically relevant model of preeclampsia in mice, and are consistent with a potential causative role for AVP in preeclampsia in humans. © 2014 American Heart Association, Inc.

    C1q is the first recognition subcomponent of the complement classical pathway, which in addition to being synthesized in the liver, is also expressed by macrophages and dendritic cells (DCs). Trophoblast invasion during early placentation results in accumulation of debris that triggers the complement system. Hence, both early and late components of the classical pathway are widely distributed in the placenta and decidua. In addition, C1q has recently been shown to significantly contribute to feto-maternal tolerance, trophoblast migration, and spiral artery remodeling, although the exact mechanism remains unknown. Pregnancy in mice, genetically deficient in C1q, mirrors symptoms similar to that of human preeclampsia. Thus, regulated complement activation has been proposed as an essential requirement for normal successful pregnancy. Little is known about the molecular pathways that regulate C1q expression in pregnancy. PU.1, an Ets-family transcription factor, is required for the development of hematopoietic myeloid lineage immune cells, and its expression is tissue-specific. Recently, PU.1 has been shown to regulate C1q gene expression in DCs and macrophages. Here, we have examined if PU.1 transcription factor regulates decidual C1q expression. We used immune-histochemical analysis, PCR, and immunostaining to localize and study the gene expression of PU.1 transcription factor in early human decidua. PU.1 was highly expressed at gene and protein level in early human decidual cells including trophoblast and stromal cells. Surprisingly, nuclear as well as cytoplasmic PU.1 expression was observed. Decidual cells with predominantly nuclear PU.1 expression had higher C1q expression. It is likely that nuclear and cytoplasmic PU.1 localization has a role to play in early pregnancy via regulating C1q expression in the decidua during implantation.

    Ectopic pregnancy is a high-risk condition that occurs in 2% of reported pregnancies. This percentage is fivefold higher than that registered in the 1970s. Since 1970 there has been a two-fold increase in the ratio of ectopic pregnancies to all reported pregnancies in Hungary and in 2012 7.4 ectopic pregnancies per thousand registered pregnancies were reported. Recently, the majority (80%) of cases can be diagnosed in early stage, and the related mortality objectively decreased in the past few decades to 3.8/10,000 ectopic pregnancies. If a woman with positive pregnancy test has abdominal pain and/or vaginal bleeding the physician should perform a work-up to safely exclude the possibility of ectopic pregnancy. The basis of diagnosis is ultrasonography, especially vaginal ultrasound examination and measurement of the β-subunit of human chorionic gonadotropin. The ultrasound diagnosis is based on the visualization of an ectopic mass rather than the inability to visualize an intrauterine pregnancy. In some questionable cases the diagnostic uterine curettage or laparoscopy may be useful. The actuality of this topic is justified by practical difficulties in obtaining correct diagnosis, especially in the early gestational time.

However, evidence points towards low expression of these proteins, especially HLA-G, being associated with reduced fertility. To clarify...

  8. HLA-G in human early pregnancy: Control of uterine immune cell activation and likely

    Full Text Available Despite a number of controversies, the functional importance of human leukocyte antigen G (HLA-G in early human pregnancy is now sustained by a large amount of sound data. Membrane-bound and soluble HLA-G isoforms, either as β2-microglobulin-free or -associated as monomers or dimers, are expressed by different trophoblast subpopulations, the only fetal-derived cells that are directly in contact with maternal cells (maternal-fetal interfaces. Trophoblast HLA-G is the specific ligand of multiple cellular receptors present in maternal immune and non-immune cells, including CD8, leukocyte immunoglobulin-like receptor (LILR B1, LILRB2, killer cell immunoglobulin-like receptor (KIR 2DL4, and possibly CD160. Trophoblast HLA-G specific engagement of these cellular receptors triggers either inhibitory or activating signals in decidual CD8 + T cells, CD4 + T cells, natural killer (NK cells, macrophages, dendritic cells, or endothelial cells. Such HLA-G-receptor specific interactions first contribute to limit potentially harmful maternal anti-paternal immune response by impairment of decidual NK cell cytotoxicity, inhibition of CD4 + and CD8 + T-cell and B-cell proliferation, and induction of apoptosis of activated CD8 + T cells. Second, these HLA-G specific interactions contribute to stimulate placental development through secretion of angiogenic factors by decidual NK cells and macrophages, and to provide a protective effect for the outcome of pregnancy by the secretion of interleukin (IL-4 by decidual trophoblast antigen-specific CD4 + T cells.

    The differentiation of human endometrial epithelium is a dynamic event that occurs throughout the menstrual cycle and early pregnancy. The structural transformation and differentiation of human uterine luminal and glandular epithelium of early human pregnancy (n=14) was investigated ultrastructurally and immunohistochemically using antibodies against cytokeratin (CT), endothelial marker CD31, Fas, and proliferating cell nuclear antigen (PCNA). Ultrastructurally, luminal epithelial cells showed distinctive euchromatic nuclei with prominent nucleoli and relatively loose cell membranes in all poles (apical to basal). Subcellular components were easily recognized in luminal epithelium except in degenerating cells. Mainly two cell types, dark and clear cells, formed the glandular epithelium. In the early gestation period, microvilli were abundant on the apical and apico-lateral poles of these cells. Only a few cytoplasmic projections were observed in dark cells. Numerous cilia were observed on the apical pole of some clear cells, located at the adluminal segment. In contrast, dark cells lacked cilia, nuclear channels, or giant mitochondrial profiles. Glycogen synthesis and apocrine secretion were recognizable for several days during early gestation. The apocrine secretory activity differed among dark cells of the glandular epithelium. The immunoreactivity of PCNA and Fas, and ultrastructural observations in the glandular epithelium suggest that, even in different segments of the same gland, epithelial cells do not regress during early gestation, but proliferate, perhaps representing a resistance against trophoblastic invasion. These morphological and molecular changes suggest that both luminal and glandular epithelium may play an important role in cellular defense and limitation for trophoblastic invasion during early pregnancy since plasma membrane alterations of the surface epithelium take place at the apical, basal and lateral poles compared to early secretory phase

    {sup 18}F-FDG is the most widely used PET radiopharmaceutical. Nevertheless, no data for {sup 18}F-FDG uptake in the human placenta have been reported. We recently reported on embryo dosimetry in a woman who underwent an {sup 18}F-FDG PET/CT scan during early pregnancy. In the present work we attempt an in vivo quantification of the {sup 18}F-FDG uptake by the placenta. The 27-y-old woman received 320 MBq of {sup 18}F-FDG for a follow-up study for Hodgkin's lymphoma and was later discovered to be pregnant (embryo age 8 wk). Imaging started 1 h after injection. The maximum placental tissue uptake (SUVmax) was 2.5. This value was conservatively attributed to the entire placental volume, i.e., 45 mL, a value representative of the average dimensions of a normal placenta at 8 wk. On the basis of these measurements, placenta {sup 18}F-FDG uptake in our patient was 0.19% of the injected activity. A Monte Carlo simulation was used to derive the photon dose to the embryo from the placenta (0.022 * 10{sup -2} mGy per MBq of injected {sup 18}F-FDG) and from the surrounding amniotic fluid (0.017 * 10{sup -2} mGy MBq{sup -1}). This increases our previously calculated dose (3.3 * 10{sup -2} mGy MBq{sup -1}) by only a small fraction (1.18%), which does not justify modifying the previous estimate given the overall uncertainties.

    Uterine spiral arteriole (SA) remodeling in early pregnancy involves a coordinated series of events including decidual immune cell recruitment, vascular cell disruption and loss, and colonization by placental-derived extravillous trophoblast (EVT). During this process, decidual SA are converted from narrow, muscular vessels into dilated channels lacking vasomotor control. We hypothesized that this extensive alteration in SA architecture must require significant reorganization and/or breakdown of the vascular extracellular matrix (ECM). First trimester decidua basalis (30 specimens) was immunostained to identify spiral arterioles undergoing trophoblast-independent and -dependent phases of remodeling. Serial sections were then immunostained for a panel of ECM markers, to examine changes in vascular ECM during the remodeling process. The initial stages of SA remodeling were characterized by loss of laminin, elastin, fibrillin, collagen types III, IV and VI from the basement membrane, vascular media and/or adventitia, and surrounding decidual stromal cells. Loss of ECM correlated with disruption and disorganization of vascular smooth muscle cells, and the majority of changes occurred prior to extensive colonization of the vessel wall by EVT. The final stages of SA remodeling, characterized by the arrival of EVT, were associated with the increased mural deposition of fibronectin and fibrinoid. This study provides the first detailed analysis of the spatial and temporal loss of ECM from the walls of remodeling decidual SA in early pregnancy.

  13. Early pregnancy azathioprine use and pregnancy outcomes.

    2012-02-01

    BACKGROUND: Azathioprine (AZA) is used during pregnancy by women with inflammatory bowel disease (IBD), other autoimmune disorders, malignancy, and organ transplantation. Previous studies have demonstrated potential risks. METHODS: The Swedish Medical Birth Register was used to identify 476 women who reported the use of AZA in early pregnancy. The effect of AZA exposure on pregnancy outcomes was studied after adjustment for maternal characteristics that could act as confounders. RESULTS: The most common indication for AZA use was IBD. The rate of congenital malformations was 6.2% in the AZA group and 4.7% among all infants born (adjusted OR: 1.41, 95% CI: 0.98-2.04). An association between early pregnancy AZA exposure and ventricular\\/atrial septal defects was found (adjusted OR: 3.18, 95% CI: 1.45-6.04). Exposed infants were also more likely to be preterm, to weigh <2500 gm, and to be small for gestational age compared to all infants born. This effect remained for preterm birth and low birth weight when infants of women with IBD but without AZA exposure were used as a comparison group. A trend toward an increased risk of congenital malformations was found among infants of women with IBD using AZA compared to women with IBD not using AZA (adjusted OR: 1.42, 95% CI: 0.93-2.18). CONCLUSIONS: Infants exposed to AZA in early pregnancy may be at a moderately increased risk of congenital malformations, specifically ventricular\\/atrial septal defects. There is also an increased risk of growth restriction and preterm delivery. These associations may be confounded by the severity of maternal illness.

    Abnormal placentation is a common pathogenic mechanism of many placenta-mediated complications of late pregnancy, including pre-eclampsia, fetal growth restriction, stillbirth, and placental abruption. During successful placentation, the trophoblast (which is a semi-allograft) is not rejected by decidual immune cells because of maternal immune tolerance, mainly induced by human leukocyte antigen G (HLA-G). Deficient HLA-G expression seems to be associated with the development of complications of pregnancy. The aim of this study was to determine whether low soluble HLA-G (sHLA-G) levels in maternal blood at the beginning of pregnancy may be associated with subsequent placenta-mediated complications. For this retrospective case-control study, 117 cases of placenta-mediated complications of pregnancy and 234 controls with uneventful pregnancy were selected. Plasma sHLA-G levels were measured at 11-13 weeks' gestation by the enzyme-linked immunosorbent assay method in blood samples previously obtained at first-trimester prenatal screening for chromosomal fetal abnormalities. Women who subsequently developed placenta-mediated complications had significantly lower sHLA-G levels at the beginning of pregnancy (median, 43.08 IU/mL) than controls (median, 49.10 IU/mL; P = 0.008). An sHLA-G level lower than 43.50 IU/mL at the end of the first trimester was associated with a twofold increased risk of developing a pregnancy complication (odds ratio, 1.82; 95% confidence interval, 1.22-2.73). The strongest association, although only moderately strong, was observed with severe pre-eclampsia (odds ratio, 2.66; 95% confidence interval, 1.08-6.56). Placenta-mediated complications of pregnancy may be associated with low sHLA-G levels in the first trimester, suggesting a potential role of sHLA-G in the early stages of placentation. © 2017 Japan Society of Obstetrics and Gynecology.

    Elevation in placental corticotropin-releasing hormone (pCRH) during the last trimester of pregnancy has been associated with an increased risk for preterm delivery. Less is known about the consequences for the human fetus exposed to high levels of pCRH early in pregnancy. pCRH levels were measured in 138 pregnant women at least once at 15, 20 and 25 weeks of gestation. At 25 weeks of gestation, fetal heart rate (FHR) responses to a startling vibroacoustic stimulus (VAS) were recorded as an index of maturity. pCRH levels at 15 weeks of gestation, but at no later point, predicted FHR responses to the VAS. Fetuses exposed to the lowest concentrations of pCRH at 15 weeks of gestation exhibited a distinguishable response to the VAS, whereas fetuses exposed to higher levels of pCRH did not respond. The findings suggest that exposure to low levels of pCRH early in gestation may be optimal and associated with a response pattern indicating greater maturity. (c) 2009 S. Karger AG, Basel.

    Objective To study the role of IFN-γ /IL-10 cytokines on IL-10 receptor gene and protein expression of human decidual stromal cells(DSC) in human early pregnancy in vitro.Methods Human DSC was isolated and cultured in vitro, and the expression of IL-10R1 and IL-10R2 gene was analyzed after cells had been treated with TH2-type cytokines IL-10 and TH1-type cytokines IFN-γ within 60 min with semiquantitative reverse transcriptase-PCR, then the influence of IL-10 and IFN-γ on expression of IL-10R protein was examined by first trimester DSC using flow cytometry. In addition,the vitality of DSC was detected by MTT.Results IL-10R1 mRNA levels of DSC treated with IL-10 (10 ng/ml) reached the peak level within 15 min, and were significantly lower at 30 min, then were not detected at 45 min. The expression of IL-10R1 were induced to moderate level by IFN-γ(10 ng/ml)within 30 min, and reduced to undetected levels at 60 min. There was no significant difference of IL-10R2 expression (P>0.05) between treated and not with the abovementioned cytokines. The IL-10R protein expression and vitality of DSC were significantly enhanced by IL-10 (10 ng/ml) and IFN-γ (10 ng/ml) which treated DSC 48 h (P<0. 05).Conclusion IL-10 and IFN-γ may play an important role of biologic function in early pregnancy by influencing IL-10R expression of DSC.

  18. Phytoestrogens in Human Pregnancy

    Full Text Available Background. The hormonal milieu associated with pregnancy has become a focus of interest owing to potential links with the developmental origins of health and disease. Phytoestrogens are hormonally active plant-derived chemicals that may have an impact on human reproductive processes. However, developmental exposure to phytoestrogens has not been well characterized and thus our objective was to quantify phytoestrogen exposure during pregnancy and lactation. Methods. Women in the second trimester of pregnancy entered the study during counseling for prenatal genetic information. Women who had an indication for a genetic amniocentesis on the basis of late maternal age were approached for inclusion. They completed an environmental questionnaire; a sample of amniotic fluid was collected for karyotype, blood was collected from women during pregnancy and at birth, from the umbilical cord and breast milk. Samples were tested for the presence of daidzein and genistein by GC Mass Spectroscopy. Findings. Phytoestrogens are commonly found in pregnant women’s serum and amniotic fluid during pregnancy. There is a sex difference in the concentrations with higher levels in amniotic fluid containing female fetuses. This difference was not present in maternal serum. Soy ingestion increases amniotic fluid phytoestrogen concentrations in female and male fetuses. The presence and concentrations of phytoestrogens did not differ in relation to common pregnancy complications or preexisting infertility.

Both of these hypotheses derive from an adaptive view of pregnancy sickness that proposes the function of pregnancy sickness is to decrease the likelihood of ingestion of foods with toxins or teratogens.

  1. The Small-Conductance Ca2+-Activated Potassium Channel, Subtype SK3, in the Human Myometrium Is Downregulated in Early Stages of Pregnancy

    2013-01-01

    Full Text Available The human myometrium is mainly relaxed during pregnancy, but, up to term, contractions become more coordinated and forceful in order to initiate delivery. Small conductance Ca2+-activated K+ channels (SK channels in human myometrium have been shown to be downregulated in late pregnancy. The aim was to investigate the presence of SK2 and SK3 in the human myometrium from nonpregnant women, pregnant women at term, and pregnancies delivered preterm and, in addition, to characterize the time of downregulation of these channels. Using qRT-PCR, we observed significantly lower levels of mRNA for SK2 than for SK3 in the nonpregnant tissue. The mRNA levels of SK3 were significantly reduced in tissue from pregnancies at term and pregnancies resulting in preterm deliveries, whereas no downregulation for SK2 was observed. Western blotting confirmed the qRT-PCR results. Using immunohistochemical staining, both SK2 and SK3 were detected in endometrial glandular epithelium. We conclude that SK3 mRNA is downregulated early in pregnancy—at least among those that result in preterm deliveries. Furthermore, we find that SK channels are expressed not only in the uterine smooth muscle but also in the endometrial epithelium.

    Imtnunohistochemical assessment of estrogen recceptor(ER) and progesterone receptors(PR) were performed using monoetonat antibodies to the receptors. A totalof 81 samples. from pregnant women at 5-13 weeks of gestation were immunostained by peroxidase anti-peroxidase method (PAP). hnmunostaining pattern of PR in early pregnant decidua was similar to that of the late luteal phase of normal endometrium characterized by little reaction in supecfieiat glandular epithelia and retatively intense in stroma. Positive stainig was atsa revealed in structure of blood vessels including pericyte and smooth muscle cells. An interesting finding is that endothelial cells Of the vessels expressed PR which has not been reported in normal cyclic endometrium. The endothelial nature of their PR partitive cell was further confirmed by immunostaining of specific endothelial marker, Factor VⅢ. The trophoblast population in villi anddecidua also showed positive reaction inctnding villous trophoblast, column andinterstitial trophobtast. In eontrast to PR, little ER were revealed in deteected tissue.

    This review summarizes information regarding how human energy metabolism is affected by pregnancy, and current estimates of energy requirements during pregnancy are presented. Such estimates can be calculated using either increases in basal metabolic rate (BMR) or increases in total energy expenditure (TEE). The two modes of calculation give similar results for a complete pregnancy but different distributions of energy requirements in the three trimesters. Recent information is presented regarding the effect of pregnancy on BMR, TEE, diet-induced thermogenesis, and physical activity. The validity of energy intake (EI) data recently assessed in well-nourished pregnant women was evaluated using information regarding energy metabolism during pregnancy. The results show that underreporting of EI is common during pregnancy and indicate that additional longitudinal studies, taking the total energy budget during pregnancy into account, are needed to satisfactorily define energy requirements during the three trimesters of gestation.

    The erythropoietin (EPO) belongs to the family of angiogenic factors, which is regulated by Hypoxia-inducible factor- 1α (HIF-1α). As known, EPO are expressed in human villi and decidua, but the function is not clear. In this study, we investigated the expression and roles of HIF-1α, EPO and its receptor (EPOR) in the biological functions of trophoblast and decidual stromal cell (DSC) in human early pregnancy. The expression of EPO, EPOR and HIF-1α was evaluated in the villi and deciduas by RT-PCR and immunohistochemistry. Thereafter, we silenced HIF-1α expression in HTR-8/SVneo cell line and decidual stromal cells (DSCs). The effects of EPO on the proliferation and apoptosis of trophoblasts and DSCs, and activation of signal molecules were investigated by BrdU proliferation assay, flow cytometry and western blot, respectively. We have observed that the HIF-1α silence results in the lower expression of EPO in trophoblasts and DSCs. The anti-EPO neutralizing antibody can inactivate the phosphorylation of STAT5 and activate p38 of these cells in a dosage-dependent manner. Furthermore, the expressions of EPO, EPOR and HIF-1α in the villi and decidua from the unexplained miscarriage were significantly lower than that of the normal early pregnancy. This study suggests that HIF-1α may regulate the expression of EPO, which plays a favorable regulatory role in the proliferation and survival of human first-trimester trophoblast cells and DSCs via inactivating p38 and activating STAT5 in an autocrine manner, while the inadequate EPO expression at maternal-fetal interface may lead to pregnancy wastage in humans.

    In addition to its role in the prevention of neural tube defects, folic acid has many other physiological functions, including cell proliferation, DNA replication, and antioxidant protection. The aim of this study was to determine the role that folic acid has in regulating placental trophoblast development. Placental explants from placentae at gestational age 7 wk (n = 3) were cultured in folic acid at concentrations of 10(-6) M, 10(-8) M, and 10(-10) M. Extravillous trophoblast (EVT) invasion was assessed following 6-day culture, and explants were used for immunohistochemical evaluation of proliferation (MKI67) and apoptosis (active caspase 3). In addition, an array was performed on cell culture supernatants to examine a range of matrix metalloproteinases (MMPs) and tissue inhibitors of MMPs (TIMPs). Folic acid increased the invasion of EVT cells in this explant model by between 83% and 19% (P = 0.005), and this was associated with increased MKI67 positivity and decreased active caspase 3 positivity; this effect was concentration dependent and showed a biphasic response. In addition, culture in folic acid increased vascular density, as determined by anti-CD31 immunostaining (P = 0.05). The increase in EVT invasion correlated with increased placental explant secretion of MMP2 (P = 0.01), MMP3 (P = 0.01), and MMP9 (P = 0.02). This study demonstrates that folic acid is potentially important in a number of crucial early stages of placental development, including EVT invasion, angiogenesis, and secretion of MMPs, and highlights the need for further studies to address the benefit of longer-term folic acid supplementation throughout pregnancy to prevent pregnancy disorders associated with deficient placental development, including preeclampsia.

    Most cases of urolithiasis in pregnancy are managed conservatively either with ureteric stents or percutaneous nephrostomy tubes, which need to be changed at regular intervals. Definitive management of the stone is usually delayed till after delivery. We describe a patient who presented with pyonephrosis in the fifth week of gestation, due to a stone obstructing the right ureteropelvic junction. This was managed by insertion of a nephrostomy tube. She declined nephrostomy tube/stent changes during the rest of her pregnancy and requested termination as an alternative. She successfully underwent percutaneous nephrolithotomy in the 14th week of pregnancy, with radiation exposure strictly localised to the kidney for 6 s. A healthy male baby was delivered at term.

  11. Shifts in Color Discrimination during Early Pregnancy

    2012-04-01

    Full Text Available The present study explores two hypotheses: a women during early pregnancy should experience increased color discrimination ability, and b women during early pregnancy should experience shifts in subjective preference away from images of foods that appear either unripe or spoiled. Both of these hypotheses derive from an adaptive view of pregnancy sickness that proposes the function of pregnancy sickness is to decrease the likelihood of ingestion of foods with toxins or teratogens. Changes to color discrimination could be part of a network of perceptual and physiological defenses (e.g., changes to olfaction, nausea, vomiting that support such a function. Participants included 13 pregnant women and 18 non-pregnant women. Pregnant women scored significantly higher than non-pregnant controls on the Farnsworth-Munsell (FM 100 Hue Test, an objective test of color discrimination, although no difference was found between groups in preferences for food images at different stages of ripeness or spoilage. These results are the first indication that changes to color discrimination may occur during early pregnancy, and is consistent with the view that pregnancy sickness may function as an adaptive defense mechanism.

    The effect of laser on anti-early pregnancy in rabbits showed that laser in combination with HPD could induce necrosis of blastocysts and complete absorption. The anti-fertility efficiency of the combined treatment was more effective than that of the He-Ne laser or the HPD treatment alone. The fluorescence spectrum of HPD determined by PNQ3 showed that its affinity to embryonic tissue was about 4 times greater than that to uterine tissue. This may underlie the mechanisms of anti-early pregnancy of the laser. The operation of artificial abortion is a routine method to terminate early pregnancy. Though it is simple and easy, its syndrome and complications can not be absolutely avoided. Many antifertility drugs have been reported, however, they often bring in general reaction. Our present work is to explore a new way of anti-early pregnancy in rabbits by means of the light inhibitory and light sensitive effects of laser. It is a quite safe and painless treatment without expanding and scraping of the uterus.

  13. Notch2 controls prolactin and insulin-like growth factor binding protein-1 expression in decidualizing human stromal cells of early pregnancy.

    Full Text Available Decidualization, the transformation of the human uterine mucosa into the endometrium of pregnancy, is critical for successful implantation and embryonic development. However, key regulatory factors controlling differentiation of uterine stromal cells into hormone-secreting decidual cells have not been fully elucidated. Hence, we herein investigated the role of the Notch signaling pathway in human decidual stromal cells (HDSC isolated from early pregnancy samples. Immunofluorescence of first trimester decidual tissues revealed expression of Notch2 receptor and its putative, membrane-anchored interaction partners Jagged1, Delta-like (DLL 1 and DLL4 in stromal cells whereas other Notch receptors and ligands were absent from these cells. During in vitro differentiation with estrogen/progesterone (E2P4 and/or cyclic adenosine monophosphate (cAMP HDSC constitutively expressed Notch2 and weakly downregulated Jagged1 mRNA and protein, measured by quantitative PCR (qPCR and Western blotting, respectively. However, increased levels of DLL1 and DLL4 were observed in the decidualizing cultures. Transfection of a Notch luciferase reporter and qPCR of the Notch target gene hairy and enhancer of split 1 (HES1 revealed an induction of canonical Notch activity during in vitro differentiation. In contrast, treatment of HDSC with a chemical Notch/γ-secretase inhibitor decreased cAMP/E2P4-stimulated Notch luciferase activity, HES1 transcript levels and mRNA expression of the decidual marker genes prolactin (PRL and insulin-like growth factor binding protein 1 (IGFBP1. Similarly, siRNA-mediated gene silencing or antibody-mediated blocking of Notch2 diminished HES1, PRL and IGFBP1 mRNA levels as well as secreted PRL protein. In summary, the data suggest that canonical, Notch2-dependent signaling plays a role in human decidualization.

    Despite a rising prevalence worldwide, there is limited data on pregnancy outcome among African women with prepregnancy or early pregnancy obesity. This was a case-control study to determine the prevalence of maternal obesity in early pregnancy and compare the subsequent pregnancy outcome between 201 women with obesity and 201 non-obese controls in a University Teaching Hospital in Nigeria. The prevalence of obesity in early pregnancy was 9.63%. Obesity was significantly associated with advanced maternal age and parity > or =1. It was also a risk factor for pregnancy induced hypertension, admissions during pregnancy, caesarean delivery and associated with 5th minute apgar score Obesity in early pregnancy is a risk factor for adverse pregnancy outcome among pregnant Nigerian women. This information should be utilised by physicians to improve the outcome of pregnancy and promote safe motherhood.

    By using the Ladisch partitioning and microscale-analysis of HPTLC the comparative quantitative and qualitative studies of gangtiosides (Gg) and neutral gtycosphingotipids ( N-GSL ) compositions from human chorionic villi tissues of normal early pregnant women and women treated with mifepristone, norethisterone (NET) and tamoxifen (TAM) were reported in this paper. The patterns of Gg and N-GSL in three treated groups were similar to those in normal pregnant group, The total values of Gg from the ckorionic villi tissues reduced significantly in three treated groups (P<0. 01), In all treated groups, the amounts of NeuNAC-Gal-Glc-cer (GM3) , NeuNAC-NeuNAC-Gal-Gtc-cer ( GD3) and Gal-GalNAC-(NeuNAC)-Gal-Glc-eer(GM1 ) were decreased significantly compared with those in normal (P<0. 01 or P<0. 05), In NET and TAM groups, Neu NAC-Gal-GalNAC-(NeuNAC-NeuNAC )-Gal-Glc-cer( GT16 ) was markedly lower than that in normal (P<0. 01), The total values of N-GSL extracted from the chorionic villi tissues were obviously higher in mifepristone and TAM groups than those in normal (P<0. 01). The Gal-Gte-cer(LacCer) (CDH) and Gal-Gal-Glc-cer(Gat-LacCer) (CTH)were greatly increased in mifepristone group as compared with normal (P<0. 05 ), Paragloboside : Gat-GalNAC-Gal-Gtc-cer (PG) in NETgroup was significantly higher than that in normal (P<0. 01 ).

    Pregnancy at an early age has a strong protective effect against breast cancer in humans and rodents. Postulated mechanisms underlying this phenomenon include alterations in the relative dynamics of hormone and growth factor-initiated cell fate-determining signaling pathways within the hierarchically organized mammary gland epithelium. Recent studies in epithelial cell subpopulations isolated from mouse and human mammary glands have shown that early pregnancy decreases the proportion of hormone receptor-positive cells and causes pronounced changes in gene expression as well as decreased proliferation in stem/progenitor cells. The changes include downregulation of Wnt and transforming growth factor β (TGFβ) signaling. These new findings highlight the importance of cell-cell interactions within the mammary gland epithelium in modulating cancer risk and provide potential targets for breast cancer prevention strategies.

    During human and mammalian pregnancy,endogenous progesterone is the dominant hormone since it is not only essential for conception and implantation,but also needed throughout pregnancy.Progesterone provided the effects of prevention and treatment in human pregnancy by certain mechanisms.If one considers prevention or treatment with progestogens in human pregnancy,that all progestogens are progestogenic,if one condsiders the progestogens for prevention and therapeutic approaches,nowadays,only two progenstogens can be considered fully suitable for prevention and treatment in human pregnancy:progesterone and dydrogesteone.This review introduced the mechanism of progesterone and dydrogesterone in pregnancy and treatment in human.

    Full Text Available To explore the frequency and weight that psychosocial risk factors predispose to outcomes of early pregnancy and scholar dropout, a descriptive review was conducted. Materials and Meth­ods: A search and review of the results reported by observational studies in the PubMed data­base indexed from July 27, 2010 until July 25, 2013 was performed, restricting the search to studies in humans, Spanish or English written, not made in countries in Africa or Asia. Search was widened to LILACS database for the years 2006 to 2013 for Latinamerican countries. For inclusion, all case-control studies comparing different types of interventions and psychosocial risk factors in adolescents were eligible. Results: The review suggests violence experienced dur­ing adolescence, sexual abuse, belonging to a low socioeconomic status, low self-esteem, eating behavior disorders, smoking, alcoholism and drug addiction, mental disorders, early initiation of sex, poor family ties, lack of access to information, and resources for family planning as main psychosocial factors related to early pregnancy and scholar dropout in adolescents. Conclusions: Both risk factors associated with pregnancy and scholar dropout were described, and interven­tions targeting the described risk factors could potentially contribute to the reduction of these outcomes were described.

    Conservative treatment of metastatic germ-cell tumor of the ovary does not exclude the possibility of pregnancy in the future. Serum beta-human chorionic gonadotropin (beta-hCG) serves as pregnancy test, and has also been proven to be a useful marker for ovarian germ-cell tumors. This paper is a case report of a 19-year-old patient who was admitted to a district hospital in emergency due to pelvic pain, amenorrhoea, and free fluid in the pelvis. Laboratory tests demonstrated slight increase in beta-hCG serum concentration and transvaginal ultrasound (TVUS) showed no evidence of gestational sac in the uterus. At the age of 14, the patient was diagnosed with malignant germ-cell tumor of the left ovary in FIGO Stage IV and was treated with four courses of chemotherapy according to TGM-95 protocol with etoposide, ifosfamide, and cisplatin, followed by conservative surgery and adjuvant two courses of cytostatics. The initial diagnosis was recurrence of ovarian malignancy and the patient was referred to an oncology center. Wait-and-see approach and repeated ultrasound examination confirmed a normal intrauterine pregnancy which concluded with the delivery of a healthy newborn through cesarean section.

    Although pre-pregnancy weight status and early pregnancy lipid profile are known to influence blood pressure course during pregnancy, little is known about how these two factors interact. The association between pre-pregnancy weight status and blood pressure course during pregnancy was assessed in the prospective ABCD study and the role (independent/mediating/moderating) of early pregnancy lipid profile in this association was determined. We included 2500 normal weight (lipids [median (IQR): 13 (12-14) weeks of gestation] and blood pressure during pregnancy [mean (SD) = 10 (2.3)]. Lipids (triglycerides, total cholesterol, apolipoprotein A1, apolipoprotein B and free fatty acids) were divided into tertiles. Multilevel piecewise linear spline models were used to describe the course of systolic and diastolic blood pressure (SBP/DBP) in four time periods during gestation for overweight and normal weight women. Both SBP (5.3 mmHg) and DBP (3.9 mmHg) were higher in overweight compared to normal weight women and this difference remained the same over all four time periods. The difference in SBP and DBP was not mediated or moderated by the lipid profile. Lipid profile had an independent positive effect on both SBP (range 1.3-2.2 mmHg) and DBP (0.8-1.1 mmHg), but did not change blood pressure course. Both pre-pregnancy weight status and early pregnancy lipid profile independently increase blood pressure during pregnancy. Improving pre-pregnancy weight status and early pregnancy lipid profile might result in a healthier blood pressure course during pregnancy.

    OBJECTIVE To investigate the extent to which Danish women attending antenatal care plan their pregnancies and to determine the association between pregnancy planning and the intake of folic acid, alcohol consumption and smoking habits prior to conception and before the 16th week of gestation. METHODS A cross-sectional survey of 258 women. intake of folic acid, alcohol consumption and smoking. Pregnancy planning was assessed by the London Measure of Unplanned Pregnancy (LMUP) and the five graded Swedish Pregnancy Planning Scale. RESULTS Most (77%) of the participants reported that their pregnancies were very or fairly well planned. Higher median LMUP scores were observed in women taking folic acid (p planning and 98% of those with a low degree of planning had not taken folic acid prior to pregnancy. Binge drinking during early pregnancy was reported by 20% of women with a high degree of planned pregnancy and 31% of those with a low degree (p = 0.1). CONCLUSION Pregnancy planning was associated with a healthier lifestyle but still many women could improve their lifestyle in connection to pregnancy. Their level of alcohol consumption is higher than that recommended for best pregnancy outcome.

    Recent observational studies suggest that mean birth weight and body fat growth in the first year of life have increased continuously over the last decades. Both elevated birth weight and early fat mass are potential risk factors for childhood obesity. Experimental and limited clinical data suggest that the dietary ratio of n-6 to n-3 fatty acids (FAs) during pregnancy is critical for early adipose tissue growth. The aim of this randomized controlled study is to examine the effect of the supplementation with n-3 long-chain polyunsaturated FAs and reduction in the n-6/n-3 ratio in the diet of pregnant women/breast-feeding mothers on adipose tissue growth in their newborns using various methods for the assessment of body fat mass. Measurement of skinfold thickness in the newborn is the primary outcome parameter. Two hundred and four pregnant women will be recruited before the 15th week of gestation and randomly assigned to either active intervention or an isocaloric control diet. This upcoming study will explore the potential of this dietary approach to limit early adipose tissue growth and may contribute to the development of a new strategy for the primary prevention of childhood obesity. 2009 S.

    Serum human placental lactogen (hPL) levels were measured in duplicate with a radioimmunoassay in 206 serum samples at 30 and 36 weeks' gestation from women with normal singleton pregnancies (75) or pregnancies with twins (37). One triplet pregnancy was also studied. The results show a significant elevation of hPL in the women with twin pregnancies at both the 30th (7.0 vs 6.0 microgram/ml) and the 36th (9.2 vs 7.4 microgram/ml) weeks. One-third of the twin pregnancies had values of hPL in excess of 8.0 microgram/ml at 30 weeks and more than half had values in excess of 9.0 microgram/ml at 36 weeks. The triplet pregnancy had an hPL value of 11.0 microgram/ml at 36 weeks' gestation. These data support the potential usefulness of serum hPL measurements in the screening profile for the detection of high-risk pregnancies.

    Spontaneous abortion refers to pregnancy loss up to the end of 22 weeks' (21(+7)) gestation. Currently, the terminology suggests early pregnancy loss or early pregnancy failure. Miscarriage occurs in 10-20% of pregnancies, and most of them take place up to 13 weeks'gestation. Management in the case of vaginal bleeding in women with a confirmed pregnancy requires a physical examination (with a speculum), and a biochemical and ultrasound diagnosis. Conservative, pharmacological or surgical management can be offered to patients with an incomplete miscarriage. The pharmacological method of proceeding in miscarriages is recommended by many scientific societies (ACOG, RCOG), and WHO, as well as in manuals for students and for obstetrician-gynecologists developed by leading experts in Poland. The procedure for pharmacological treatment with mizoprostol is: 1. Pregnancy under 9 weeks gestation: 800 mg vaginally, and if there is no effect after 4 h another 400 mg vaginally or orally. 2. Pregnancy over 9 weeks gestation: up to 4 x 400 mg every 3 hours. 3. In the absence of any effect after 36 hours from the start of the treatment, a surgical procedure is recommended. 4. The prevention of chlamydia infection in each patient: 1 g of metronidazole rectally and one dose of 1 g azithromycin, or 2 x 100 mg of doxycycline for 7 days. The legal aspects regarding the administrative proceedings after early pregnancy failure relate to the correct reporting of feat death on proper forms.

    Full Text Available An early and accurate diagnosis of reproductive dysfunctions or aberrations is crucial to better reproductive management in livestock. High reproductive efficiency is a prerequisite for high life-time production in dairy animals. Early pregnancy diagnosis is key to shorten the calving interval through early identification of open animals and their timely treatment and rebreeding so as to maintain a postpartum barren interval close to 60 days. A buffalo, the most important dairy animal in the Indian subcontinent, is known for problems related to high calving interval, late puberty, and high incidence of anestrus. Lack of reliable cow-side early pregnancy diagnosis methods further aggravates the situation. Several methods of pregnancy diagnosis are being practiced in bovine species, yet none qualifies as the ideal pregnancy diagnosis method due to the inherent limitations of sensitivity, accuracy, specificity, speed, and ease of performing the test. The advancement of molecular techniques like proteomics and their applications in animal research has given a new hope to look for pregnancy biomarker molecules in these animals. This review attempts to examine common pregnancy diagnosis methods available for dairy animals, while assessing the usefulness of the modern technologies in detecting novel pregnancy markers and designing future strategies for research in this area.

  16. Genetic Conflict in Human Pregnancy

    OpenAIRE

    1993-01-01

    Pregnancy has commonly been viewed as a cooperative interaction between a mother and her fetus. The effects of natural selection on genes expressed in fetuses, however, may be opposed by the effects of natural selection on genes expressed in mothers. In this sense, a genetic conflict can be said to exist between maternal and fetal genes. Fetal genes will be selected to increase the transfer of nutrients to their fetus, and maternal genes will be selected to limit transfers in excess of Soma m...

    Full Text Available Background: There are few studies focusing on women's experiences of early pregnancy. Medical and psychological approaches have dominated the research. Taking women's experiences seriously during early pregnancy may prevent future suffering during childbirth. Aim: To describe and understand women's first time experiences of early pregnancy. Method: Qualitative study using a phenomenological hermeneutic approach. Data were collected via tape-recorded interviews in two antenatal care units in Sweden. Twelve first time pregnant women in week 10–14, aged between 17 and 37 years participated. Results: To be in early pregnancy means for the women a life opening both in terms of life affirming and suffering. The central themes are: living in the present and thinking ahead, being in a change of new perspectives and values and being in change to becoming a mother. Conclusions: The results have implications for the midwife's encounter with the women during pregnancy. Questions of more existential nature, instead of only focusing the physical aspects of the pregnancy, may lead to an improvement in health condition and a positive experience for the pregnant woman.

    Shannon K Flood-Nichols

    Full Text Available Vitamin D deficiency is a common problem in reproductive-aged women in the United States. The effect of vitamin D deficiency in pregnancy is unknown, but has been associated with adverse pregnancy outcomes. The objective of this study was to analyze the relationship between vitamin D deficiency in the first trimester and subsequent clinical outcomes.This is a retrospective cohort study. Plasma was collected in the first trimester from 310 nulliparous women with singleton gestations without significant medical problems. Competitive enzymatic vitamin D assays were performed on banked plasma specimens and pregnancy outcomes were collected after delivery. Logistic regression was performed on patients stratified by plasma vitamin D concentration and the following combined clinical outcomes: preeclampsia, preterm delivery, intrauterine growth restriction, gestational diabetes, and spontaneous abortion.Vitamin D concentrations were obtained from 235 patients (mean age 24.3 years, range 18-40 years. Seventy percent of our study population was vitamin D insufficient with a serum concentration less than 30 ng/mL (mean serum concentration 27.6 ng/mL, range 13-71.6 ng/mL. Logistic regression was performed adjusting for age, race, body mass index, tobacco use, and time of year. Adverse pregnancy outcomes included preeclampsia, growth restriction, preterm delivery, gestational diabetes, and spontaneous abortion. There was no association between vitamin D deficiency and composite adverse pregnancy outcomes with an adjusted odds ratio of 1.01 (p value 0.738, 95% confidence intervals 0.961-1.057.Vitamin D deficiency did not associate with adverse pregnancy outcomes in this study population. However, the high percentage of affected individuals highlights the prevalence of vitamin D deficiency in young, reproductive-aged women.

    Results: Offspring whose mothers had any AR symptoms during early pregnancy showed a significantly higher adjusted odds ratio for the onset of AR in offspring than those whose mothers had no symptoms during pregnancy (adjusted Odds Ratio: 6.26, p=0.036. However, the symptoms of AR during late pregnancy showed no effects on the odds ratio. In contrast, the presence or absence of AR symptoms during early or late pregnancy showed no association with the prevalence of food allergy, atopic dermatitis or asthma in offspring. Conclusions: Our results suggest the presence of possible epigenetic mechanisms regulating the onset of AR in humans presumably through increased organ-specific hypersensitivity.

    A miscarriage can be very traumatic for a couple and their immediate family. The aim of this study was to assess, using the Perinatal Grief Scale (PGS), whether the type of early pregnancy loss influences the severity of grief and whether the presence of living children influences the severity of grief. Over a period of 6 months in 2008, seventy five patients were recruited for the study, of which 7 (9.3%) had molar pregnancies, 20 (26.7%) had ectopic pregnancies, 43 (573%) had a miscarriage and 5 (6.7%) had recurrent miscarriages. In this study there was no significant difference in severity of grief, between women that had a miscarriage and ectopic pregnancy (p = 0.14) or, between women that had a miscarriage and a molar pregnancy (p = 0.85). Women who had experienced a ectopic pregnancy did not have a higher grief intensity than the women that had a molar pregnancy (p = 0.75). However, for women with a child, the grief intensity significantly increases with the number of miscarriages (p = 0.015). Women with no children with an ectopic pregnancy grieve significantly more than those with a child (p = 0.019). An appointment for the \\'Miscarriage Clinic\\' should be offered to all of these women but special attention should be paid to those in the categories most at risk

    Antenatal anxiety symptoms are not only a health problem for the expectant mother. Research has found that maternal anxiety may also have an impact on the developing baby. Therefore, it is important to estimate the prevalence of maternal anxiety and associated factors. The current study aims to estimate the prevalence of anxiety symptoms during the first trimester of pregnancy and to identify associated risk factors. Secondly, to investigate other factors associated with anxiety during early pregnancy including fear of childbirth and a preference for cesarean section. In a population-based community sample of 1,175 pregnant women, 916 women (78%) were investigated in the first trimester (gestation week 8-12). The Hospital Anxiety Depression Scale (HADS-A) was used to measure anxiety symptoms. The prevalence of anxiety symptoms (HADS-A scores≥8 during pregnancy) was 15.6% in early pregnancy. Women under 25 years of age were at an increased risk of anxiety symptoms during early pregnancy (OR 2.6, CI 1.7-4.0). Women who reported a language other than Swedish as their native language (OR 4.2, CI 2.7-7.0), reported high school as their highest level of education (OR 1.6, CI 1.1-2.3), were unemployed (OR 3.5, CI 2.1-5.8), used nicotine before pregnancy (OR 1.7, CI 1.1-2.5), and had a self-reported psychiatric history of either depression (OR 3.8, CI 2.6-5.6) or anxiety (OR 5.2, CI 3.5-7.9) before their current pregnancy were all at an increased risk of anxiety symptoms during early pregnancy. Anxiety symptoms during pregnancy increased the rate of fear of birth (OR 3.0, CI 1.9-4.7) and a preference for cesarean section (OR 1.7, CI 1.0-2.8). Caregivers should pay careful attention to history of mental illness to be able to identify women with symptoms of anxiety during early pregnancy. When presenting with symptoms of anxiety, the women might need counseling and or treatment in order to decrease her anxiety.

    Full Text Available OBJECTIVE : A study was planned to find out the cause of false positive urinary pregnancy test in early pregnancy as some times when ultrasonography is done on these women with positive pregnancy test , they are found to be non - pregnant . Such reports on false positive urinary pregnancy test , confirmed by ultrason ography are few and therefore the study was planned. METHOD: A total number of 218 women who came to the Deptt. o f Radiology Era’s Lucknow Medical College Lucknow , for routine first trimester ultrasonographies from April 2012 to Dec 2012 were analyzed . All th ese women had their urinary pregnancy test positive tested by commonly available test kits. Some of them were found to be non - pregnant on ultrasonography. The study was conducted for nine months . RESULT: Out of the 218 women who came with positive urinary pregnancy test were examined by ultrasonography. Out of these 18(8.2% cases were found to be non - pregnant and the test was false positive. These women had performed the urinary pregnancy test by themselves and out of these 4 cases were confirmed by hospit al/ lab. These women had performed the urinary pregnancy test in the months from April 2012 to September 2012 , when atmospheric temperature is high and weather is dry. CONCLUSION : Care should be taken to avoid drying of the test membrane in the pregnancy car d test kit by replacing it in its packet soon after adding the urine sample. The result should be noted within the time mentioned on the pack. Such instructions should be followed strictly while testing the urine for pregnancy.

    . Similarly, between the groups, there were no differences in pregnancy adaptation with similar trends in cardiovascular function changes from pre-pregnancy to 6 weeks gestation. Whilst this is the first study to investigate preconception and early pregnancy haemodynamic and arterial function in relation to viability, the relatively modest number of miscarriages may not be sufficient to show subtle differences in haemodynamic changes if these were present. This study suggests that pre-pregnancy haemodynamic and arterial function is unlikely to be the causal link between miscarriages and future cardiovascular disease. Our findings suggests that factors other than the presence of a viable embryo drive cardiovascular changes in early pregnancy. This study raises new questions about miscarriages as an independent risk event which predisposes women to increased cardiovascular risk later in life.

    Cerebral venous thrombosis (CVT) is an uncommon cause of stroke, accounting to less than 1% of all strokes. We describe a pregnant woman with a massive CVT in early pregnancy, complicated by status epilepticus. The mother was treated with levetiracetam, lacosamide, and enoxaparin throughout pregnancy. A male infant was born on pregnancy week 36, weighing 2.2kg. Both levetiracetam and and lacosamide were present in cord blood in levels similar to those in maternal blood. The infant was partially breast-fed and experienced poor feeding and sleepiness, starting to resolve after two first weeks. Milk samples were drawn 5 days after the delivery and a blood sample from the infant 3 days later. Lacosamide level in milk was low, resulting in an estimated relative infant dose of 1.8% of the maternal weight-adjusted daily dose in a fully breast-fed infant. This is the first case describing lacosamide use during pregnancy and lactation.

Objectives: To investigate the association between maternal exposure to tobacco smoking during pregnancy and early age (< 2 yr. leukemia (EAL. Methods: A hospital-based multicenter case-control study aiming to explore EAL risk factors was carried out in Brazil during 1999-2007. Data were collected by direct interview with the biological mothers using a standardized questionnaire. The present study included 675 children, being 193 acute lymphoblastic leukemia (ALL, 59 acute myeloid leukemia (AML, and 423 controls, being the latter age frequency matched and paired by area of residence with the cases. Unconditional logistic regression was performed, and odds ratios (OR on the association between tobacco smoking (3 months before pregnancy, during pregnancy, and 3 months after delivery and EAL were ascertained after adjustment for selected variables (maternal age at birth and education, birth weight, infant skin color, and oral contraceptives use during pregnancy.Results: Smoking was reported by 17.5% of case mothers and 20.6% of controls´. Among women who reported to have smoked 20 or more cigarettes during the index pregnancy, an adjusted OR = 5.28 (95% C.I. 1.40-19.95 for ALL was observed. Heavy smoking during breastfeeding yielded an adjusted risk estimate for ALL, OR = 7.78 (95% C.I. 1.33-45.5. No dose-response effect was observed according to smoking exposure during pregnancy and EAL. An association between secondhand smoking during pregnancy or breastfeeding was not observed. Conclusion: An association between maternal smoking and AAL in the offspring was restricted to women who have reported an intense exposure to tobacco smoke during pregnancy and breastfeeding.

    Understanding associations between pregnancy and HIV disease progression is critical to provide appropriate counseling and care to HIV-positive women. From 2006 to 2011, women less than age 40 with incident HIV infection were enrolled in an early HIV infection cohort in Kenya, Rwanda, South Africa, Uganda, and Zambia. Time-dependent Cox models evaluated associations between pregnancy and HIV disease progression. Clinical progression was defined as a single CD4 measurement <200 cells/μl, percent CD4 <14%, or category C event, with censoring at antiretroviral (ART) initiation for reasons other than prevention of mother-to-child transmission (PMTCT). Immunologic progression was defined as two consecutive CD4s ≤350 cells/μl or a single CD4 ≤350 cells/μl followed by non-PMTCT ART initiation. Generalized estimating equations assessed changes in CD4 before and after pregnancy. Among 222 women, 63 experienced clinical progression during 783.5 person-years at risk (8.0/100). Among 205 women, 87 experienced immunologic progression during 680.1 person-years at risk (12.8/100). The association between pregnancy and clinical progression was adjusted hazard ratio [aHR] = 0.7; 95% confidence interval (CI): 0.2, 1.8. The association between pregnancy and immunologic progression was aHR = 1.7; 95% CI: 0.9, 3.3. Models controlled for age; human leukocyte antigen alleles A*03:01, B*45, B*57; CD4 set point; and HIV-1 subtype. CD4 measurements before versus after pregnancies were not different. In this cohort, pregnancy was not associated with increased clinical or immunologic HIV progression. Similarly, we did not observe meaningful deleterious associations of pregnancy with CD4s. Our findings suggest that HIV-positive women may become pregnant without harmful health effects occurring during the pregnancy. Evaluation of longer-term impact of pregnancy on progression is warranted.

    Periconception supplementation with folic acid is recommended until 12 gestational weeks to prevent neural tube defects. Doses of folic acid contained in supplements and timing and length of use during pregnancy vary. The effects of status in periconception and pregnancy folate, cobalamin, betaine and their interactions on one carbon metabolism (1C), as well as the global effect of 1C on foetal growth and pregnancy outcome, are reviewed. Results from prospective studies are reviewed. Cessation of folic acid supplement use after the first trimester is associated with a sharp drop in plasma folate status and enhanced conversion of betaine to dimethylglycine. Dimethylglycine production is also higher in mothers with low folate status than in those with normal-high folate status. The effects of high doses of folic acid on one carbon metabolism in mothers with low early pregnancy cobalamin status and on foetal growth are also reviewed. Several studies report that moderately elevated early pregnancy fasting plasma total homocysteine (tHcy) is inversely associated with birth weight and a predictor of intrauterine growth retardation. There is also evidence for increased risk of preterm birth when maternal folate status is low.

    Full Text Available INTRODUCTION: Nearly 20% of all confirmed pregnancies end in spontaneous abortion. Misoprostol’s use in early pregnancy failure is varied and dose and route are not well established. AIM: To study the efficacy of sublingual misoprostol in causing expulsion of products of conception in early pregnancy failure. METHODS: Women with an ultrasound diagnosis of early pregnancy failure, less than 12 weeks gestation were included in the study. Tablet Misoprostol 600 mcg was given six hourly sublingually for 3 doses. All observations were noted and analyzed. RESULTS: Mean gestational age was 7.946+1.2 weeks. Mean induction abortion interval was 18.241+1.2 hours. Women with gestational age six to eight weeks had least mean induction-abortion interval time of 17.38+2. Mean dose required was 1564mcg.Efficacy of protocol was 92.85% in achieving complete abortion. CONCLUSION: The regime had 92.85% efficacy, acceptability (90% and few side effects. Thus by using a lower dose and appropriate interval between two doses (six hours, the side effects were lessened with high efficacy

  15. Human Immunodeficiency Virus Infection in Pregnancy

    Full Text Available The incidence and prevalence of human immunodeficiency virus (HIV infection in women of child-bearing age continue to increase both internationally and in Canada. The care of HIV-infected pregnant women is complex, and multiple issues must be addressed, including the current and future health of the woman, minimization of the risk of maternal-infant HIV transmission, and maintenance of the well-being of the fetus and neonate. Vertical transmission of HIV can occur in utero, intrapartum and postpartum, but current evidence suggests that the majority of transmission occurs toward end of term, or during labour and delivery. Several maternal and obstetrical factors influence transmission rates, which can be reduced by optimal medical and obstetrical care. Zidovudine therapy has been demonstrated to reduce maternal-infant transmission significantly, but several issues, including the short and long term safety of antiretrovirals and the optimal use of combination antiretroviral therapy in pregnancy, remain to be defined. It is essential that health care workers providing care to these women fully understand the natural history of HIV disease in pregnancy, the factors that affect vertical transmission and the management issues during pregnancy. Close collaboration among a multidisciplinary team of knowledgeable health professionals and, most importantly, the woman herself can improve both maternal and infant outcomes.

    Human parvovirus B19 infection is widespread. Approximately 30-50% of pregnant women are non-immune and vertical transmission is common following maternal infection in pregnancy. Fetal infection may be associated with a normal outcome but fetal death may also occur without ultrasound evidence of infections sequelae. B19 infection should be considered in any case of non-immune hydrops. Diagnosis is mainly through serology and PCR. Surveillance requires sequential ultrasound and Doppler screening for signs of fetal anemia, heart failure, and hydrops. Immunoglobulins antiviral and vaccination are not yet available but intrauterine transfusion in selected cases can be lifesaving. PMID:21040396

    There is a need to elucidate what affects the implantation and early pregnancy course in pregnancies conceived with assisted reproductive technology (ART) so that pregnancy rates and outcomes can be improved. Our aim was to determine the role of maternal Helicobacter pylori infection. We did a prospective study of 187 infertile couples undergoing intracytoplasmic sperm injection (ICSI) and segregated those according to underlying infertility etiology. We assessed the status of H. pylori IgG antibodies and anti-CagA IgG antibodies by ELISA assay. All pregnancies were followed for early pregnancy loss (EPL, first 12 weeks). The likelihood of H. pylori infection increased with age (1.01, 95% confidence interval [CI]: 1.0-1.13; P = 0.040) but there was no association with EPL. Women infected with CagA-positive strains were more likely to have EPL (19.39, 95% CI: 1.8-208.4; P = 0.014). Women with tubal factor or ovulatory disorder infertility were more likely to abort early (12.95, 95% CI: 1.28-131.11; P = 0.030, 10.84, 95% CI: 1.47-80.03; P = 0.020, respectively). There was no association between EPL and age, number of embryos formed or transferred, or number of oocytes retrieved. Our findings suggest that infection with CagA-positive H. pylori strains is linked to an increase in women's potential to abort early (possibly through increased release of inflammatory cytokines). In addition, tubal factor and ovulatory disorder infertility are linked to EPL after ICSI due to unknown mechanisms. Proposals to eradicate H. pylori infection prior to ICSI could lead to a decrease in EPL after ART.

    Low vitamin D status in pregnancy was proposed as a risk factor of preeclampsia. We assessed the effect of vitamin D supplementation (4,400 vs. 400 IU/day), initiated early in pregnancy (10-18 weeks), on the development of preeclampsia. The effects of serum vitamin D (25-hydroxyvitamin D [25OHD]) levels on preeclampsia incidence at trial entry and in the third trimester (32-38 weeks) were studied. We also conducted a nested case-control study of 157 women to investigate peripheral blood vitamin D-associated gene expression profiles at 10 to 18 weeks in 47 participants who developed preeclampsia. Of 881 women randomized, outcome data were available for 816, with 67 (8.2%) developing preeclampsia. There was no significant difference between treatment (N = 408) or control (N = 408) groups in the incidence of preeclampsia (8.08% vs. 8.33%, respectively; relative risk: 0.97; 95% CI, 0.61-1.53). However, in a cohort analysis and after adjustment for confounders, a significant effect of sufficient vitamin D status (25OHD ≥30 ng/ml) was observed in both early and late pregnancy compared with insufficient levels (25OHD preeclampsia (FDR preeclampsia incidence in the intention-to-treat paradigm. However, vitamin D levels of 30 ng/ml or higher at trial entry and in late pregnancy were associated with a lower risk of preeclampsia. Differentially expressed vitamin D-associated transcriptomes implicated the emergence of an early pregnancy, distinctive immune response in women who went on to develop preeclampsia.

    Hypertensive diseases are directly responsible for 24 % of maternal deaths in India. A screening method is yet to be discovered to reduce the morbidity and mortality related to it. Serum triglyceride (TG) levels are reported to increase in hypertensive pregnant women. To predict pregnancy-induced hypertension (PIH) by serum triglyceride values. This study is a prospective cohort study that was conducted over three hundred normotensive, primigravida women with singleton pregnancy at 14-20 weeks of gestation. These were divided into two groups on the basis of their TG concentration estimated at 14-20 weeks of gestation. The pregnancy was then followed till delivery and, signs and symptoms of PIH were noted in both the groups. Out of 300 women, 210 women completed the study. Fifty-nine women developed PIH and 151 women remained normotensive. Among 59 women, 45 women had raised TG values i.e., ≥160 mg/dL and 14 women were with normal TG levels i.e., hypertriglyceridemia were found to be at higher risk of developing early-onset PIH. Our study supports the evidence that early pregnancy hypertriglyceridemia is associated with an increased risk of PIH.

    Recent study has suggested that innate immune system might play an important role in pregnancy progression. In this study, to investigate whether NK cells and NKT cells, instead of T cells, are the dominant populations of peripheral blood in early pregnancy, flow cytometry was used to detect the percentage and intracellular cytokine expressions of T cells, NK cells, NKT cells in peripheral blood of non-pregnant women and early pregnant women.In our result, the percentages of NK cells and NKT cells were significantly increased in pregnancy compared to non-pregnancy. However, the percentage of T cells was not changed. We did not detect the Th2-dominance of total lymphocytes or T cells in peripheral blood of early pregnant women and there were also no significant changes of type 1 and type 2 cytokines in T cells, but IFN-γ production in both NK and NKT cells was decreased in early pregnancy. These results suggest that the innate immune system including NK cells and NKT cells should play a pivotal role in pregnancy progression. Type 1/type 2 shift mechanisms in innate immune system during the human early pregnancy should be paid more attention.

    In the present study, we aimed to evaluate the effects of high doses of dexamethasone (DEX) in early pregnancy on pregnancy outcomes. Pregnant BALB/c mice were treated with high-dose DEX in the experimental group or saline in the control group on gestational days (GDs) 0.5 to 4.5. Pregnant mice were sacrificed on GDs 7.5, 13.5, or 18.5 and their peripheral blood, placentas, fetuses, and uterine tissue were collected. Decidual and placenta cell supernatants were examined to evaluate the effect of DEX on the proliferation of mononuclear cells, the quantity of uterine macrophages and uterine natural killer (uNK) cells, and levels of progesterone and 17β-estradiol, as determined by an 3-(4,5-dimethylthiazole-2-yl)-2,5-diphenyltetrazolium bromide assay, immunohistochemistry, and enzyme-linked immunosorbent assay, respectively. We also were measured fetal and placental growth parameters on GD 18.5. We found that high doses of DEX were associated with an increased abortion rate, enhancement of the immunosuppressive effect of the decidua, alterations in placental growth parameters, decreased progesterone and 17β-estradiol levels, and a reduced frequency of macrophages and uNK cells. Our data suggest that the high-dose administration of DEX during early pregnancy negatively affected pregnancy outcomes.

    Only few studies exist regarding the risk of a teratogenic effect of tramadol when used in early pregnancy. Using the Swedish Medical Birth Register, women (deliveries in 1997-2013) who had reported the use of tramadol in early pregnancy were identified. Maternal characteristics and concomitant drug use were analyzed. Among 1,682,846 women (1,797,678 infants), 1751 (1776 infants) had used tramadol, 96 of the infants had a congenital malformation and 70 of them were relatively severe. The adjusted odds ratio for a relatively severe malformation was 1.33 (95% CI 1.05-1.70). The odds ratios for cardiovascular defects (1.56, 95% CI 1.04-2.29) and for pes equinovarus (3.63, 95% CI 1.61-6.89) were significantly increased. The study suggests a teratogenic effect of tramadol but the risk increase is moderate. Copyright © 2015 Elsevier Inc. All rights reserved.

    To assess uterine contractions in early pregnancies using transvaginal color Doppler sonography (TVCDS) and to determine the role of uterine contractions in the diagnosis of early pregnancy failure. 76 patients with abnormal pregnancy diagnosed by sonography or histopathology up to 10 weeks of gestation and 38 normal pregnant women as the control group were examines with TVCDS. The presence of uterine contractions was determined by complete or partial disappearance of the color flow signals of vessels within myometrium, and the direction, amplitude (grade 1-3), and interval of uterine contractions were also evaluated. Uterine contractions were identified in 42 (55.3%) of 76 patients with abnormal pregnancy, whereas they were detected only in 2 (5.3%) of 38 normal pregnant women who had initial grade 1 contraction but disappeared in the follow-up study. In 26 patients with blighted ovum or missed abortion, 15 patients (57.7%),showed uterine contraction of grade 1 in 3 cases, grade 2 in 8 cases, and grade 3 in 4 cases and interval from 45 seconds to 5 minutes. In 30 patients with inevitable or incomplete abortion, 23 patients (76.6%) showed uterine contraction of grade 1 in 2 cases, grade 2 in 9 cases, and grade 3 in 12 cases and interval from 1 to 5 minutes. 4 (20%) of 20 patients with threatened abortion had uterine contraction of grade 2 and interval from 2 to 4 minutes. The presence of uterine contractions was significantly different in abnormal pregnancies compared with that of normal and also among the tree different groups of abnormal pregnancies, but the amplitude did not differ.

  6. A molar masquerading as an ectopic pregnancy in the early first trimester: a salutary lesson.

    The authors report a case in which a molar pregnancy was mistaken for an ectopic pregnancy in the early first trimester. This confusion delayed diagnosis and caused distress; follow-up led to the final diagnosis of complete hydatidiform mole. Correct preoperative diagnosis of molar pregnancy by ultrasound in early pregnancy may be tricky. It is important to obtain histological evidence to make the final diagnosis of gestational trophoblastic disease. While relatively rare, consideration of molar pregnancy in the differential diagnosis of early pregnancy loss may avoid unnecessary distress.

    Full Text Available Background. The question is debated on whether maternal hypothyroidism or use of thyroxin in early pregnancy affects the risk for infant congenital malformations. Objectives. To expand the previously published study on maternal thyroxin use in early pregnancy and the risk for congenital malformations. Methods. Data from the Swedish Medical Birth Register were used for the years 1996–2011 and infant malformations were identified from national health registers. Women with preexisting diabetes or reporting the use of thyreostatics, anticonvulsants, or antihypertensives were excluded from analysis. Risk estimates were made as odds ratios (ORs or risk ratios (RRs after adjustment for year of delivery, maternal age, parity, smoking, and body mass index. Results. Among 23 259 infants whose mothers in early pregnancy used thyroxin, 730 had a major malformation; among all 1 567 736 infants, 48012 had such malformations. The adjusted OR was 1.06 (95% CI 0.98–1.14. For anal atresia the RR was 1.85 (95% CI 1.00–1.85 and for choanal atresia 3.14 (95% CI 1.26–6.47. The risk of some other malformations was also increased but statistical significance was not reached. Conclusions. Treated maternal hypothyroidism may be a weak risk factor for infant congenital malformations but an association with a few rare conditions is possible.

    To determine the prevalence and explore predictors of Complementary and Alternative Medicine (CAM) use during early pregnancy. A questionnaire survey of pregnant women (500) attending for mid trimester scan at the maternity services in Grampian, North-East Scotland. Outcome measures included; CAM used; vitamins and minerals used; independent predictors of use; views and experiences. Descriptive and inferential statistical analysis. The response rate was 66%. Two thirds of respondents (63%) reported using CAM, excluding vitamins and minerals, during early pregnancy. Respondents reported using a total of 28 different CAM modalities, of which oral herbal products were the most common (37% of respondents, 25 different products). The independent predictors of CAM use identified were: use by family and friends (OR 4.1, 95% CI 2.3-7.3, ppregnancy (OR 2.4, 95% CI 1.2-4.8, p=0.014). In comparison to prescribed medicines, most users were uncertain if CAM were safer (63%), more effective (66%), free from possible adverse effects (46%) or drug-CAM interactions (50%). Despite the majority of respondents being uncertain about their safety and effectiveness, CAM modalities and CAM products are widely used during the early stages of pregnancy in this study population. The role of family and friends rather than health professionals in the decision to use CAM may be of concern and requires further investigation. Copyright © 2014 Elsevier Ireland Ltd.

    An early pregnancy risk scale, with scores ranging from 11 to 66 points from lower to higher risk, was constructed using variables associated with teenager's pregnancy. This scale was applied to 3000 female teenagers, coming from Metropolitan Santiago public schools. The sample was divided in three risk groups: group A (high risk) with scores equal or over 35 points, group B (low risk) with scores equal or below 20 points and group B (intermediate risk) with scores between 20.1 and 34.9 points. These girls were followed during 2 years. During this period, 84 girls became pregnant, 24 of 184 (13%) in group A, 60 of 2332 (2.6%) in group C and none of 307 in group B. There were 104 school desertions in group A and 37 in group B. To study associations and analyze risk, the sample was divided in two risk groups: high, with scores over 27 and low, with scores below 27. There was a high association between pregnancy risk score and the occurrence of pregnancy (RR 5.25 p school desertion (RR 3.32 p School desertion was predicted with a 74% sensitivity and 56% specificity.

    BACKGROUND An ectopic pregnancy is a pregnancy which occurs outside of the uterine cavity, and over 98% implant in the Fallopian tube. Tubal ectopic pregnancy remains the most common cause of maternal mortality in the first trimester of pregnancy. The epidemiological risk factors for tubal ectopic pregnancy are well established and include: tubal damage as a result of surgery or infection (particularly Chlamydia trachomatis), smoking and in vitro fertilization. This review appraises the data to date researching the aetiology of tubal ectopic pregnancy. METHODS Scientific literature was searched for studies investigating the underlying aetiology of tubal ectopic pregnancy. RESULTS Existing data addressing the underlying cause of tubal ectopic pregnancy are mostly descriptive. There are currently few good animal models of tubal ectopic pregnancy. There are limited data explaining the link between risk factors and tubal implantation. CONCLUSIONS Current evidence supports the hypothesis that tubal ectopic pregnancy is caused by a combination of retention of the embryo within the Fallopian tube due to impaired embryo-tubal transport and alterations in the tubal environment allowing early implantation to occur. Future studies are needed that address the functional consequences of infection and smoking on Fallopian tube physiology. A greater understanding of the aetiology of tubal ectopic pregnancy is critical for the development of improved preventative measures, the advancement of diagnostic screening methods and the development of novel treatments.

    The endocrinology was studied throughout pregnancy in reindeer (Rangifer tarandus tarandus) located in Oulu, Finland (65 degrees N, 25 degrees E) with 13 captive, semi domestic adult females. Blood samples were analyzed for plasma progesterone (P4), estradiol (E2) and estrone sulphate (E1SO4), 15-ketodihydro-PGF2alpha (PG-metabolite) and pregnancy associated glycoproteins (PAG). The mean plasma P4 concentration peaked twice during gestation: at around 24 and three weeks prior to calving. In pregnant females the plasma PAG concentration increased over basal concentrations 21-30 days after the estimated day of conception and peaked at the time of calving. The concentrations of E2 and E1SO4 remained low until 60 days before calving when a rapid increase was found for both hormones. The mean plasma concentration of PG-metabolite increased throughout pregnancy to a maximum at parturition. The estimated mean (range) gestation length was 216 (212-220) days. Judged from measures on reproductive organs collected from 86 free-ranging, semi-domestic female reindeer of unknown age presented for slaughter at Roros, Norway (63 degrees N, 11 degrees E) in the second week of December 1999, it was concluded that the breeding season lasted from early September until the end of November. The results also showed that plasma PAG concentration could provide a tool for detection of pregnancy in reindeer.

    Preeclampsia is a pregnancy-specific syndrome that causes substantial maternal and fetal morbidity and mortality. The etiology is incompletely understood, and there is no clinically useful screening test. Current metabolomic technologies have allowed the establishment of metabolic signatures of preeclampsia in early pregnancy. Here, a 2-phase discovery\\/validation metabolic profiling study was performed. In the discovery phase, a nested case-control study was designed, using samples obtained at 15±1 weeks\\' gestation from 60 women who subsequently developed preeclampsia and 60 controls taking part in the prospective Screening for Pregnancy Endpoints cohort study. Controls were proportionally population matched for age, ethnicity, and body mass index at booking. Plasma samples were analyzed using ultra performance liquid chromatography-mass spectrometry. A multivariate predictive model combining 14 metabolites gave an odds ratio for developing preeclampsia of 36 (95% CI: 12 to 108), with an area under the receiver operator characteristic curve of 0.94. These findings were then validated using an independent case-control study on plasma obtained at 15±1 weeks from 39 women who subsequently developed preeclampsia and 40 similarly matched controls from a participating center in a different country. The same 14 metabolites produced an odds ratio of 23 (95% CI: 7 to 73) with an area under receiver operator characteristic curve of 0.92. The finding of a consistent discriminatory metabolite signature in early pregnancy plasma preceding the onset of preeclampsia offers insight into disease pathogenesis and offers the tantalizing promise of a robust presymptomatic screening test.

    Proving incest from tissue obtained by abortion early in pregnancy can be a challenge. Problems include the small quantity of embryonic tissue in the products of conception, and the mixing of DNA from mother and embryo. In many cases, this amorphous material cannot be grossly segregated into maternal and fetal components. Thus, morphological discrimination requires microscopy to select relevant tissue particles from which DNA can be typed. This combination of methods is reliable and efficient. In this article, we present two cases of incest discovered by examination of products of conception.

    To examine peak serum levels of the β-subunit of human chorionic gonadotropin (β-hCG) for prediction of early pregnancy outcomes among women with recurrent spontaneous abortion (RSA). In a retrospective study, the medical records of pregnant women with a history of RSA treated at Sun Yat-sen Memorial Hospital, China, between January 2011 and July 2013 were reviewed. Serum β-hCG had been measured twice weekly from 5 to 13weeks of pregnancy, and pregnancy was monitored by transvaginal ultrasonography to 13(+6)weeks. Optimal cutoff for peak β-hCG level was determined by receiver operator characteristic curve analysis and Youden index. Women were divided into four groups on the basis of optimal peak β-hCG cutoff and pregnancy outcome (pregnancy at 13weeks or spontaneous abortion). Peak β-hCG levels and length of pregnancy at this peak were examined. Overall, 1240 patients were included. The optimal cutoff value of peak β-hCG was 88 468IU/L, with a sensitivity, specificity, positive predictive value, and negative predictive value for successful pregnancy of 95.6%, 88.0%, 95.6%, and 89.0%, respectively. A faster rise in β-hCG, higher peak β-hCG, and longer pregnancy length at peak β-hCG were associated with successful early pregnancy. A cutoff value of serum β-hCG of 88 000IU/L could be used to predict early pregnancy outcomes for women with a history of RSA. Copyright © 2016. Published by Elsevier Ireland Ltd.

    , diversity, and evenness during pregnancy (P preterm birth is associated with increased vaginal microbiome instability compared to term birth. No distinct taxa were associated with preterm birth. In a predominantly African-American population, a significant decrease of vaginal microbial community richness and diversity is associated with preterm birth. The timing of this suppression appears early in pregnancy, between the first and second trimesters, suggesting that early gestation may be an ecologically important time for events that ordain subsequent term and preterm birth outcomes.

    There is growing evidence that the reproductive schedules of female mammals can be affected by conditions experienced during early development, with low parental investment leading to accelerated life-history strategies in the offspring. In humans, the relationships between early-life conditions and timing of puberty are well studied, but much less attention has been paid to reproductive behaviour. Here, we investigate associations between early-life conditions and age at first pregnancy (AFP) in a large, longitudinally studied cohort of British women (n = 4553). Low birthweight for gestational age, short duration of breastfeeding, separation from mother in childhood, frequent family residential moves and lack of paternal involvement are all independently associated with earlier first pregnancy. Apart from that of birthweight, the effects are robust to adjustment for family socioeconomic position (SEP) and the cohort member's mother's age at her birth. The association between childhood SEP and AFP is partially mediated by early-life conditions, and the association between early-life conditions and AFP is partially mediated by emotional and behavioural problems in childhood. The overall relationship between early-life adversities and AFP appears to be approximately additive.

    Full Text Available During pregnancy, many women gain excessive weight, which is related to adverse maternal and neonatal outcomes. In this study, we evaluated whether rate of gestational weight gain (RGWG in early, mid, and late pregnancy is strongly associated with adverse pregnancy outcomes. A retrospective chart review of 2,789 pregnant Korean women was performed. Weights were recorded at the first clinic visit, during the screening test for fetal anomaly, and during the 50g oral glucose challenge test and delivery, to represent early, mid, and late pregnancy, respectively. A multivariate logistic regression analysis was performed to examine the relationship between RGWG and adverse pregnancy outcomes. At early pregnancy, the RGWG was significantly associated with high risk of developing gestational diabetes mellitus (GDM, pregnancy-induced hypertension (PIH, large for gestational age (LGA infants, macrosomia, and primary cesarean section (P-CS. The RGWG of mid pregnancy was not significantly associated with any adverse pregnancy outcomes. The RGWG at late pregnancy was significantly associated with a lower risk of developing GDM, preterm birth and P-CS, but with a higher risk of developing LGA infants and macrosomia. When the subjects were divided into three groups (Underweight, Normal, and Obese, based on pre-pregnancy body mass index (BMI, the relationship between early RGWG and adverse pregnancy outcomes was significantly different across the three BMI groups. At early pregnancy, RGWG was not significantly associated to adverse pregnancy outcomes for subjects in the Underweight group. In the Normal group, however, early RGWG was significantly associated with GDM, PIH, LGA infants, macrosomia, P-CS, and small for gestational weight (SGA infants, whereas early RGWG was significantly associated with only a high risk of PIH in the Obese group. The results of our study suggest that early RGWG is significantly associated with various adverse pregnancy outcomes

    Women who undergo in vitro fertilization/embryo transfer (IVF/ET) face complicated psychological stress and negative emotions, which may affect health during pregnancy and the development of the fetus. The current literature does not address the question of whether women who become pregnant spontaneously and women who undergo IVF face similar levels of pregnancy stress. This study investigates the differences in pregnancy stress between women with spontaneous pregnancy and women with IVF/ET pregnancy living in central Taiwan during their first 20 weeks of pregnancy. A prospective, longitudinal design with repeated measures, generalized estimated equations model, Wilks' λ, and Bonferroni test was used. Purposive samples of 163 women who had undergone IVF/ET and of 94 women who had undergone spontaneous pregnancy were enrolled as participants. Pregnancy stress was measured using the Chinese version of the self-administered Pregnancy Stress Scale at the 9th, 12th, and 20th weeks of pregnancy. The psychological stress experienced by IVF participants significantly increased with gestational week during the first 20 weeks of pregnancy (p pregnancy participants. Gestational week was the main factor found to influence stress ratings for "identifying maternal role." "Altering body structure and body function" was the main factor found to influence pregnancy stress (p pregnancy stress during the first 20 weeks of pregnancy (p > .05). The results of this study provide clinical evidence that IVF/ET does not cause more stress for women than spontaneous pregnancy. However, the intensity and trend of stresses differed between these two groups. These findings suggest that nurses should consider method of pregnancy when assessing the risk of stress in expectant mothers for each gestational week and when providing appropriate care and support.

    Bleeding and pain are experienced by 20% of women during the first trimester of pregnancy. Although most pregnancies complicated by pain and bleeding tend to progress normally, these symptoms are distressing for woman, and they are also associated with an increased risk of miscarriage and ectopic pregnancy. Ultrasound is the first and often the only diagnostic modality that is used to determine location of early pregnancy and to assess its health. Ultrasound is an accurate, safe, painless and relatively inexpensive diagnostic tool, which all contributed to its widespread use in early pregnancy. Pain and bleeding in early pregnancy are sometimes caused by concomitant gynaecological, gastrointestinal, and urological problems, which could also be detected on ultrasound scan. In women with suspected intra-abdominal bleeding, ultrasound scan can be used to detect the presence of blood and provide information about the extent of bleeding. In this chapter, we comprehensively review the use of ultrasound in the diagnosis and management of early pregnancy complications. We include information about the diagnosis of gynaecological and other pelvic abnormalities, which could cause pain or bleeding in pregnancy. We also provide a summary of the current views on the safety of ultrasound in early pregnancy.

    Adiponectin is the most abundant adipose-released protein that circulates in human plasma at high concentrations. The neuropeptides orexin A (OXA, hypocretin-1) and orexin B (OXB, hypocretin-2) are derived from a common precursor peptide, prepro-orexin and are produced mainly by neurons located in the lateral hypothalamus. It has been demonstrated that the peptides such as adiponectin and orexins have an important role in the regulation of energy metabolism and neuroendocrine functions. These hormones appear to be implicated in both normal and disturbed pregnancy. The objectives of this study were to determine adiponectin and orexin concentrations in the plasma and uterine luminal fluid (ULF) of pigs during early gestation and to explore the relationships between hormone concentrations and stages of pregnancy. The greatest plasma concentrations of adiponectin were observed on days 15-16 and 27-28 of pregnancy, and the least concentrations were on days 30-32 of gestation and on days 10-11 of the oestrous cycle. In ULF, adiponectin concentrations were greater on days 15-16 of pregnancy and on days 10-11 of the oestrous cycle than on days 10-11 and days 12-13 of pregnancy. The greatest OXA concentrations in the blood plasma were noted on days 10-16 of gestation, and the least OXA concentrations were on days 27-32 of pregnancy and on days 10-11 of the oestrous cycle. Orexin A concentrations in ULF were greater on days 10-11 of the cycle than throughout pregnancy. Serum OXB concentrations were greatest on days 10-11 and 30-32 of pregnancy, and least on days 12-28 of gestation. The greatest OXB concentrations in ULF were on days 10-13 of gestation, and the least OXB concentrations were on days 15-16 of pregnancy. This is first study to demonstrate the presence of adiponectin and orexins in the serum and ULF during early pregnancy of pigs as well as the relationships between adiponectin and orexin concentrations and the stage of pregnancy.

  17. The dysfunction of CD4(+CD25(+ regulatory T cells contributes to the abortion of mice caused by Toxoplasma gondii excreted-secreted antigens in early pregnancy.

    Directory of Open Access Journals (Sweden)

    Jin-ling Chen

    Full Text Available Toxoplasma gondii is an opportunistic intracellular parasite that is highly prevalent in human and warm-blooded animals throughout the world, leading to potentially severe congenital infections. Although the abortion caused by T. gondii is believed to be dependent on the timing of maternal infection during pregnancy, the mechanism remains unclear. This study was focused on the effects of T. gondii excreted-secreted antigens on pregnant outcomes and CD4(+CD25(+ Foxp3(+ regulatory T cells at different stages of pregnancy. The results showed that in mice the frequency and suppressive function of CD4(+CD25(+ regulatory cells were diminished after injection of T. gondii excreted-secreted antigens at early and intermediate stages of pregnancy. The abortion caused by T. gondii excreted-secreted antigens at early pregnancy could be partly prevented by adoptively transferring of CD4(+CD25(+ cells from the mice injected with T. gondii excreted-secreted antigens at late pregnancy, but not from the mice with the same treatment at early pregnancy. Furthermore, T. gondii excreted-secreted antigens induced apoptosis of CD4(+CD25(+ regulatory cells of mice in early and intermediate stages of pregnancy by down-regulating their Bcl-2 expressions and Bcl-2/Bax ratio. This study provides new insights into the mechanism that T. gondii infection is the high risk factor for abortion in early pregnancy.

    Shiga toxin type 2 (Stx2), a toxin secreted by Shiga toxin-producing Escherichia coli (STEC), could be one of the causes of maternal and fetal morbimortality not yet investigated. In this study, we examined the effects of Stx2 in rats in the early stage of pregnancy. Sprague-Dawley pregnant rats were intraperitoneally (i.p.) injected with sublethal doses of Stx2, 0.25 and 0.5 ng Stx2/g of body weight (bwt), at day 8 of gestation (early postimplantation period of gestation). Maternal weight loss and food and water intake were analyzed after Stx2 injection. Another group of rats were euthanized and uteri were collected at different times to evaluate fetal status. Immunolocalization of Stx2 in uterus and maternal kidneys was analyzed by immunohistochemistry. The presence of Stx2 receptor (globotriaosylceramide, Gb3) in the uteroplacental unit was observed by thin layer chromatography (TLC). Sublethal doses of Stx2 in rats caused maternal weight loss and pregnancy loss. Stx2 and Gb3 receptor were localized in decidual tissues. Stx2 was also immunolocalized in renal tissues. Our results demonstrate that Stx2 leads to pregnancy loss and maternal morbidity in rats in the early stage of pregnancy. This study highlights the possibility of human pregnancy loss and maternal morbidity mediated by Stx2. PMID:25157355

    Exercise during pregnancy is associated with health benefits for both the mother and the fetus, and is therefore recommended in several national guidelines. Only few studies investigate whether these guideline recommendations are met. The aims of this study were 1. To assess the prevalence of pregnant women meeting the Danish recommendations for exercise during early pregnancy, 2. To identify pre-pregnancy factors associated with a lower probability for meeting the recommendations, and 3. To describe which types of exercise pregnant women prefer before and during pregnancy. We conducted a cross-sectional study based on a questionnaire during the first trimester among 7,915 women participating in the prospective Copenhagen Pregnancy Cohort. Associations were estimated by multivariate regression analyses. In early pregnancy, 38 % of the study population met the recommendation for exercise from the Danish Health and Medicines Authority (≥3.5 hours a week). Multiparity, previous miscarriage use of assisted reproductive technology, no engagement in exercise before pregnancy, smoking, pregnancy following assisted reproductive technology, overweight, not understanding Danish language and a low educational level were all factors associated a lower probability for meeting the recommendations. The preferred types of exercise before and during pregnancy were bicycling, brisk walking, running and strength training. The proportion of women engaged in any type of exercise decreased in early pregnancy with the exception of swimming and aquatic exercise. In this cohort, more than one-third met the Danish recommendation for exercise during early pregnancy. Exercise in pregnancy is still an issue to address because the most vulnerable groups of pregnant women do not exercise. This is a cause of concern because it may reflect social inequalities in health and highlights the need for a structural and systematic approach to preconception care and early antenatal counselling.

    Early pregnancy diagnosis and monitoring play an important role following embryo transfer in sheep. The aims of the current study were to investigate (i) the pattern of serum progesterone profiles in sheep carrying somatic cell nuclear transfer (SCNT)-derived (clone) pregnancies, and (ii) the frequency of pregnancy loss during development following SCNT embryo transfer. Sheep SCNT embryos were made using standard nuclear transfer techniques. Day 7 embryos were surgically transferred to oestrus-synchronized recipients (n = 27). As a control, normal fertile ewes (n = 12) were bred by natural breeding. Serum was collected from all the ewes on the day of estrus (day 0 sample), 7 days post-estrus (day 7 sample) and 19 days post-estrus (day 19 sample) and every 10 days thereafter until lambing or pregnancy loss occurred. Serum progesterone (P4) was assessed using enzyme immunoassay. Pregnancy was confirmed by ultrasound scanning on day 35 of pregnancy followed by subsequent scanning every 10 days. In control ewes, pregnancy rate on day 35 was 83.3% (10/12), whereas in the ewes that received SCNT embryos, it was 22.2% (6/27; p sheep. Further, the serum P4 levels directly reflect the degree of placental development in these two groups.

    Fe deficiency anaemia during early pregnancy has been linked with low birth weight and preterm birth. However, this evidence comes mostly from studies measuring Hb levels rather than specific measures of Fe deficiency. The present study aimed to examine the association between maternal Fe status during the first trimester of pregnancy, as assessed by serum ferritin, transferrin receptor and their ratio, with size at birth and preterm birth. In the Baby VIP (Baby's Vascular health and Iron in Pregnancy) study, we recruited 362 infants and their mothers after delivery in Leeds, UK. Biomarkers were measured in maternal serum samples previously obtained in the first trimester of pregnancy. The cohort included sixty-four (18 %) small for gestational age (SGA) babies. Thirty-three babies were born preterm (9 %; between 34 and 37 weeks). First trimester maternal Fe depletion was associated with a higher risk of SGA (adjusted OR 2·2, 95 % CI 1·1, 4·1). This relationship was attenuated when including early pregnancy Hb in the model, suggesting it as a mediator (adjusted OR 1·6, 95 % CI 0·8, 3·2). For every 10 g/l increase in maternal Hb level in the first half of pregnancy the risk of SGA was reduced by 30 % (adjusted 95 % CI 0, 40 %); levels below 110 g/l were associated with a 3-fold increase in the risk of SGA (95 % CI 1·0, 9·0). There was no evidence of association between maternal Fe depletion and preterm birth (adjusted OR 1·5, 95 % 0·6, 3·8). The present study shows that depleted Fe stores in early pregnancy are associated with higher risk of SGA.

Analyzing pregnancy-associated dynamics of the factor confers a valuable addition to the case-control studies and can help advance our understanding of the fundamentals of the factor’s involvement in pregnancy. However, as seen from the systematic literature review presented in this paper, current data set significant questions on roles of GDF15 in pregnancy. Additionally, a significant controversy is seen in the literature regarding the gestational dynamics of GDF15. Thus, we tried to contribute to the field by assessing the dynamics of serum GDF15 protein in the course of the physiological human pregnancy. We found that serum maternal GDF15 levels increase by almost two orders of magnitude with progression of pregnancy from the mid-first trimester towards the early second trimester and then towards the term. These data were further compared with those found in the literature.

    In this paper I explore some of the moral issues that could emerge from the creation of human-nonhuman chimeras (HNH-chimeras) capable of human gamete production and human pregnancy. First I explore whether there is a cogent argument against the creation of HNH-chimeras that could produce human gametes. I conclude that so far there is none, and that in fact there is at least one good moral reason for producing such types of creatures. Afterwards I explore some of the moral problems that could emerge from the fact that a HNH-chimera could become pregnant with a human conceptus. I focus on two sets of problems: problems that would arise by virtue of the fact that a human is gestated by a nonhuman creature, and problems that would emerge from the fact that such pregnancies could affect the health of the HNH-chimera.

    St. John's Wort is a herbal therapy, shown to be effective in treating mild to moderate depression; a disease common in women in their childbearing years. With a significant proportion of unplanned pregnancies, exposure to St. John's Wort into pregnancy is expected to occur. The purpose of this study was to determine whether exposure to this agent in pregnancy is associated with major malformations. We prospectively collected and followed subjects taking St. John's Wort and compared them to a matched group of pregnant women taking other pharmacologic therapy for depression and a third group of healthy women, not exposed to any known teratogens. We obtained follow-up information on 54 St. John's Wort exposed pregnancies and 108 pregnancies in the two comparator groups. Our results indicated that the rates of major malformations were similar across the three groups, with 5%, 4% and 0% in the St. John's Wort, disease comparator, and health group, respectively (p=0.26), This was not different that the 3-5% risk expected in the general population. The live birth and prematurity rates were also not different among the three groups. Though further large scale studies are still needed, this first study on the effects of St. John's Wort in human pregnancy does provide some evidence of fetal safety.

    Potential factors affecting retention of pregnancy during weeks 5-9 of gestation were studied in dairy cows and heifers (N = 211) on two farms. Cows were examined by ultrasonography for presence of a viable embryo, and sizes of the corpus luteum (CL) and of follicles > or = 5mm were recorded. Blood samples were taken at each examination and assayed for progesterone and estradiol. Overall pregnancy loss was 11.4%. Cows with two CL did not have greater concentrations of progesterone than cows with one CL and they retained fewer pregnancies (P Embryos that were lost apparently died before CL regression. Retention of pregnancy declined in cows with high body condition and as age of the cow increased. Pregnancy retention was lower in cows bred to one of four frequently-used service sires (P body condition and service sire.

    1993-01-01

    Recent attention to methanol (MeOH) as a potential alternative fuel prompted an evaluation of the chemical's effects during very early pregnancy. Rats were dosed by gavage during Days 1-8 of pregnancy at 0, 1.6, 2.4 or 3.2 g MeOH/kg/day. Groups of animals were killed on Days 9, 11 or 20 of pregnancy, and maternal, embryonic, or fetal parameters were assessed, depending on the stage of pregnancy. The decidual cell response (DCR) technique was also applied to rats treated with MeOH during pseudopregnancy. (Copyright (c) 1993 Elsevier Scientific Publishers Ireland Ltd.).

    To evaluate the advantages and disadvantages of early-early pregnancy induced abortion (EPIA). A total of 10 404 cases of EPIA performed at our hospital from January 1993 to December 2003 were retrospectively analyzed and compared with 9434 cases of common induced abortion (CIA). The amount of hemorrhage and operative duration, degree of pain, rate of induced-abortion syndrome, rate of incomplete abortion, menstrual changes and post-operative onset of Asherman's syndrome were observed and compared between 2 groups. The average age, ratio of parous cases, ratio of the cases of first-pregnancy induced abortion were not different between 2 groups (P > 0.05). The amount of hemorrhage bleeding ((4.9 ± 3.2) ml), operative duration ((90.3 ± 12.4) s), degree of pain, rate of induced-abortion syndrome, menstrual changes and the rate of Asherman's syndrome in the EPIA group were all significantly less than those in the CIA group (P abortion (0.44%) in the EPIA group was significantly higher than that (0.21%) in the CIA group (P abortion stays high.

    Few data exist on the impact of maternal weight gain on offspring despite evidence demonstrating that early-life environment precipitates risks for metabolic syndrome. We hypothesized that excessive weight gain during pregnancy results in programming that predisposes offspring to obesity and metabolic syndrome. We further hypothesized that early postweaning nutrition alters the effects of maternal weight gain on indications of metabolic syndrome in offspring. Pregnant sows and their offspring were used for these experiments due to similarities with human digestive physiology, metabolism, and neonatal development. First parity sows fed a high-energy (maternal nutrition high energy [MatHE]) diet gained 12.4 kg (42%) more weight during pregnancy than sows fed a normal energy (maternal nutrition normal energy) diet. Birth weight and litter characteristics did not differ, but offspring MatHE gilts weighed more (P pregnancy. These data indicate that excessive gestational weight gain during pregnancy in a pig model promotes early indications of metabolic syndrome in offspring that are further promoted by a high-energy postweaning diet.

    In the present study, four RIA systems (RIA-1 to -4) based on two antisera raised against ovine pregnancy-associated glycoproteins (ovPAGs), combined with an ovine or a bovine PAG tracer were used to measure PAG concentrations in plasma and milk samples of dairy ewes. Blood and milk samples were collected on different days of gestation: 0, 18, 20, 22, 25, 28, 32, 42, and 49. From day 20 onward, the PAG in plasma could be detected in all pregnant ewes using the four RIA systems. By using milk, except for RIA-1, the other systems showed a sensitivity of 100% from day 28 of gestation onward. In plasma, PAG concentrations were higher in multiple than in single pregnancies, while no clear relationship was observed in milk. In conclusion, milk is a good alternative to plasma for early pregnancy diagnosis in sheep from day 28 to day 42.

  4. Human teratogens update 2011: can we ensure safety during pregnancy?

    2012-03-01

    Anniversaries of the identification of three human teratogens (i.e., rubella virus in 1941, thalidomide in 1961, and diethylstilbestrol in 1971) occurred in 2011. These experiences highlight the critical role that scientists with an interest in teratology play in the identification of teratogenic exposures as the basis for developing strategies for prevention of those exposures and the adverse outcomes associated with them. However, an equally important responsibility for teratologists is to evaluate whether medications and vaccines are safe for use during pregnancy so informed decisions about disease treatment and prevention during pregnancy can be made. Several recent studies have examined the safety of medications during pregnancy, including antiviral medications used to treat herpes simplex and zoster, proton pump inhibitors used to treat gastroesophageal reflux, and newer-generation antiepileptic medications used to treat seizures and other conditions. Despite the large numbers of pregnant women included in these studies and the relatively reassuring results, the question of whether these medications are teratogens remains. In addition, certain vaccines are recommended during pregnancy to prevent infections in mothers and infants, but clinical trials to test these vaccines typically exclude pregnant women; thus, evaluation of their safety depends on observational studies. For pregnant women to receive optimal care, we need to define the data needed to determine whether a medication or vaccine is "safe" for use during pregnancy. In the absence of adequate, well-controlled data, it will often be necessary to weigh the benefits of medications or vaccines with potential risks to the embryo or fetus.

    During the first trimester of pregnancy, foetal endovascular trophoblasts invade into maternal spiral arteries, accumulate and form plugs in the lumen of the vessels. These plugs only allow blood plasma to seep through. Hence, during the first trimester of pregnancy, a first flow of fluids through the placental intervillous space is established, resulting in a physiological oxygen gradient between mother and foetus. The trophoblast plugs block spiral arteries until the beginning of the second...

    Bowel obstruction is rare in pregnancy, and delay in recognition can lead to serious maternal and fetal complications. Most reported causes of bowel obstruction in pregnancy (adhesions, intussusception, hernia, and carcinoma) require surgical intervention. Sigmoid volvulus is an acute surgical cause that can now be managed successfully without surgery. We report the case of 33-year-old lady who presented with a sigmoid volvulus that was successfully managed with urgent endoscopic decompression.

    ABSTRACT Mouse and human pregnancy-specific glycoproteins (PSG) are known to exert immunomodulatory functions during pregnancy by inducing maternal leukocytes to secrete anti-inflammatory cytokines that promote a tolerogenic decidual microenvironment. Many such anti-inflammatory mediators also function as proangiogenic factors, which, along with the reported association of murine PSG with the uterine vasculature, suggest that PSG may contribute to the vascular adaptations necessary for successful implantation and placental development. We observed that PSG22 is strongly expressed around the embryonic crypt on Gestation Day 5.5, indicating that trophoblast giant cells are the main source of PSG22 during the early stages of pregnancy. PSG22 treatment up-regulated the secretion of transforming growth factor beta 1 and vascular endothelial growth factor A (VEGFA) in murine macrophages, uterine dendritic cells, and natural killer cells. A possible role of PSGs in uteroplacental angiogenesis is further supported by the finding that incubation of endothelial cells with PSG22 resulted in the formation of tubes in the presence and absence of VEGFA. We determined that PSG22, like human PSG1 and murine PSG17 and PSG23, binds to the heparan sulfate chains in syndecans. Therefore, our findings indicate that despite the independent evolution and expansion of human and rodent PSG, members in both families have conserved functions that include their ability to induce anti-inflammatory cytokines and proangiogenic factors as well as to induce the formation of capillary structures by endothelial cells. In summary, our results indicate that PSG22, the most abundant PSG expressed during mouse early pregnancy, is likely a major contributor to the establishment of a successful pregnancy. PMID:22423048

  12. Risk factors and birth outcomes of anaemia in early pregnancy in a nulliparous cohort.

    Directory of Open Access Journals (Sweden)

    Gwinyai Masukume

    Full Text Available Anaemia in pregnancy is a major public health and economic problem worldwide, that contributes to both maternal and fetal morbidity and mortality.The aim of the study was to calculate the prevalence of anaemia in early pregnancy in a cohort of 'low risk' women participating in a large international multicentre prospective study (n = 5 609, to identify the modifiable risk factors for anaemia in pregnancy in this cohort, and to compare the birth outcomes between pregnancies with and without anaemia in early gestation.The study is an analysis of data that were collected prospectively during the Screening for Pregnancy Endpoints study. Anaemia was defined according to the World Health Organization's definition of anaemia in pregnancy (haemoglobin < 11g/dL. Binary logistic regression with adjustment for potential confounders (country, maternal age, having a marital partner, ethnic origin, years of schooling, and having paid work was the main method of analysis.The hallmark findings were the low prevalence of anaemia (2.2%, that having no marital partner was an independent risk factor for having anaemia (OR 1.34, 95% CI 1.01-1.78, and that there was no statistically significant effect of anaemia on adverse pregnancy outcomes (small for gestational age, pre-tem birth, mode of delivery, low birth weight, APGAR score < 7 at one and five minutes. Adverse pregnancy outcomes were however more common in those with anaemia than in those without.In this low risk healthy pregnant population we found a low anaemia rate. The absence of a marital partner was a non-modifiable factor, albeit one which may reflect a variety of confounding factors, that should be considered for addition to anaemia's conceptual framework of determinants. Although not statistically significant, clinically, a trend towards a higher risk of adverse pregnancy outcomes was observed in women that were anaemic in early pregnancy.

  13. Are female orphans at risk for early marriage, early sexual debut, and teen pregnancy? Evidence from sub-Saharan Africa.

    2009-06-01

    Female orphans are widely cited as being at risk for early marriage, early childbearing, and risky sexual behavior; however, to date no studies have examined these linkages using population-level data across multiple countries. This study draws from recent Demographic and Health Surveys from ten sub-Saharan African countries to examine the relationship between orphanhood status and measures of early marriage, early sexual debut, and teen pregnancy among adolescent girls aged 15 to 17. Results indicate that, overall, little association is found between orphanhood and early marriage or teen pregnancy, whereas evidence from seven countries supports associations between orphanhood and early sexual debut. Findings are sensitive to the use of multivariate models, type of orphan, and country setting. Orphanhood status alone may not be a sufficient targeting mechanism for addressing these outcomes in many countries; a broader, multidimensional targeting scheme including orphan type, schooling, and poverty measures would be more robust in identifying and aiding young women at risk.

    Beryllium is widely used in fatigue-resistant alloys, nuclear reactors, space device, missiles parts, electronics and other specialized purposes. Workers both in industries and mines are constantly exposed through inhalation or direct skin contact. A number of investigations have been made in different laboratories in relation to its toxicological effects in laboratory animals and humans. The lethal dose (LD/sub 50/) of beryllium nitrate through intravenous route in rats has been reported from our laboratory to be 3.16 mg/kg body weight. But not much is known about its effects on reproductive physiology. The present communication deals with the effect of beryllium nitrate on early and late pregnancy in the albino rats.

  15. Compensatory placental growth after restricted maternal nutrition in early pregnancy.

    Lumey, L H

    1998-01-01

    This study examined the effects of undernutrition in pregnancy on fetal and placental growth among infants born in 1944-1946 in The Netherlands, including infants born during the war-induced Dutch famine of 1944-1945. There was an increase in placental weight, but not in birthweight, in infants whose mothers' nutrition was compromised around conception or in the first trimester of pregnancy. Therefore, the placental index was also increased. Compared to pre-famine controls, the relative increase after first trimester exposure to undernutrition was larger in the northern part of the country (5.2 per cent, 95 per cent confidence interval 1.4, 9.0) where nutritional deprivation was presumably moderate compared to the west (3.5 per cent, 95 per cent confidence interval 0.2, 7.2) where nutritional deprivation was severe. The increase in placental weight is interpreted as compensatory for the reduction in maternal caloric intake. Whereas this suggests that pregnancy undernutrition can stimulate compensatory placental growth, the latter was only seen after first trimester undernutrition, which does not affect infant size at birth. For these infants, therefore, birthweight is not an appropriate proxy measure of undernutrition in pregnancy. These factors need to be considered in future studies relating pregnancy nutrition to adult health outcomes.

    Misoprostol can be used in the prevention of gastric ulcer in treatment with diclofenac and is used in rheumatic diseases. Since misoprostol causes contractions of the uterus, it can also be used to induce abortions when administrated vaginally. The aim of the study was to investigate if early pregnancy exposure to oral diclofenac/misoprostol was associated with miscarriage. We conducted a nationwide cohort study identifying all registered pregnancies in Denmark from 1997 to 2011. All births were identified using the Medical Birth Registry, and all records of induced abortion and miscarriage were from the National Hospital Register. Data on drug use were from the National Prescription Register. Cox proportional hazard regression models were used to calculate the hazard of miscarriage in women exposed to diclofenac/misoprostol in early pregnancy. We identified 1,338,824 pregnancies (970,491 births, 142,147 miscarriages, 226,145 induced abortions). One hundred sixty-six were exposed to diclofenac/misoprostol in the early pregnancy of which 28.3 % (47) ended up in a miscarriage compared to 10.6 % among unexposed. The adjusted hazard ratio of having a miscarriage after exposure to diclofenac/misoprostol in the first trimester was 3.6 (CI 95 % 2.6-4.9). We found an increased risk of miscarriage after exposure to diclofenac/misoprostol during the early pregnancy. Women in the fertile age should not be treated with the combination of diclofenac/misoprostol if other options were available.

    Subclinical hypothyroidism (SCH) is associated with a higher miscarriage rate. It is unclear how the thyroid function in SCH differs from that in euthyroidism during early pregnancy. We intended to determine the regulation of thyroid function in women with SCH receiving constant l-thyroxine (T4) replacement during early pregnancy as compared to euthyroid controls. This was a prospective cohort study with weekly serum sampling in eight women in early pregnancy with SCH and eight euthyroid women from week 5 to week 12 of pregnancy. Thyroid function was assessed before pregnancy. Women with SCH were treated with T4 (50 microg daily) and continued on an unchanged dose until week 12. The following parameters were measured weekly: thyrotropin (TSH), thyroglobulin, thyroxine, triiodothyronine, free thyroxine (FT4), free triiodothyronine (FT3), estradiol, progesterone, human chorionic gonadotropin, and prolactin. Although the pregestational levels of TSH were significantly higher among women with SCH as compared to euthyroid controls, the self-limited estrogen-induced increment of TSH during early pregnancy was similar in both groups. Although both SCH and ovarian hyperstimulation were associated with an intermediate rise in TSH, the pattern of thyroid function followed similar changes as in euthyroid controls and is unlikely to cause the higher miscarriage rate observed in SCH.

    Full Text Available Background. According to present views proliferation and apoptosis plays an important role in the mechanisms of placenta formation, particularly in process of vasculogenesis that begins on the third week of pregnancy. Objective: To investigate the immunohistochemical features of chorion and endometrium in women with early pregnancy losses. Methods. 98 samples of abortive and surgical material in pregnant women in terms of 4-10 weeks of pregnancy were analyzed. 48 samples were obtained from women with missed abortion (1st group, 20 samples from women with spontaneous abortion (2nd group; 20 samples from women with tubal pregnancy (3rd group; 10 samples from pregnant women with normal singleton pregnancy, after medical abortion on their own wish (control group. Histological, histochemical and immunohistochemical methods were used. Monoclonal antibodies (MAbs to Ki-67 and bcl-2 were applied. Results. Pathological picture of spontaneous abortion is characterized by the dominance of violation of blood circulation, presence of significant foci of hemorrhage occurring parallel with a pronounced disruption of apoptosis and proliferation in chorionic villi and decidual tissue, leading to the detachment of placenta. Conclusion. In 75% of cases of tubal pregnancy ectopic cytotrophoblast invasion is caused by prominent changes in the structure of the fallopian tube. First of all due to the inflammatory process and a sharp reduction of proliferation in the basal chorion and parietal deciduitis in 65% of cases. Citation: Trohimovych OV.

    Pregnancy, parity, and circulating steroid hormone levels are associated with risk of breast cancer, but little is known about hormone concentrations during pregnancy and subsequent breast cancer risk. We evaluated early pregnancy (pregnancies registered in Finland since 1983. Individuals with samples collected in the first pregnancy leading to a live birth were eligible. Breast cancer cases (n = 1,199) were identified through linkage with the Finnish Cancer Registry; 2,281 matched controls were selected using incidence density sampling. ORs were calculated using conditional logistic regression. Hormone concentrations were not associated with breast cancer overall. Estradiol was positively associated with risk of breast cancer diagnosed age hormones were associated with increased risk of estrogen receptor (ER)- and progesterone receptor (PR)-negative tumors in women age hormones and ER(+)/PR(+) disease. These data suggest a positive association between high concentrations of early pregnancy steroid hormones and risk of ER(-)/PR(-) breast cancer in women diagnosed age pregnancy hormones and risk of steroid receptor-negative cancers is needed to further characterize this association.

    Full Text Available Background: The maternal cardiovascular system undergoes progressive adaptations throughout pregnancy, causing blood pressure fluctuations. However, no consensus has been established on its normal variation in uncomplicated pregnancies. Objective: To describe the variation in systolic blood pressure (SBP and diastolic blood pressure (DBP levels during pregnancy according to early pregnancy body mass index (BMI. Methods: SBP and DBP were measured during the first, second and third trimesters and at 30-45 days postpartum in a prospective cohort of 189 women aged 20-40 years. BMI (kg/m2 was measured up to the 13th gestational week and classified as normal-weight (<25.0 or excessive weight (≥25.0. Longitudinal linear mixed-effects models were used for statistical analysis. Results: A decrease in SBP and DBP was observed from the first to the second trimester (βSBP=-0.394; 95%CI: -0.600- -0.188 and βDBP=-0.617; 95%CI: -0.780- -0.454, as was an increase in SBP and DBP up to 30-45 postpartum days (βSBP=0.010; 95%CI: 0.006-0.014 and βDBP=0.015; 95%CI: 0.012-0.018. Women with excessive weight at early pregnancy showed higher mean SBP in all gestational trimesters, and higher mean DBP in the first and third trimesters. Excessive early pregnancy BMI was positively associated with prospective changes in SBP (βSBP=7.055; 95%CI: 4.499-9.610 and in DBP (βDBP=3.201; 95%CI: 1.136-5.266. Conclusion: SBP and DBP decreased from the first to the second trimester and then increased up to the postpartum period. Women with excessive early pregnancy BMI had higher SBP and DBP than their normal-weight counterparts throughout pregnancy, but not in the postpartum period.

    Miscarriage is a common and poorly understood adverse pregnancy outcome. In this study, the authors sought to evaluate the relation between self-reported use of prenatal vitamins in early pregnancy and the risk of miscarriage. Between 2000 and 2008, 4,752 US women were prospectively enrolled in Right From the Start. Information about vitamin use was obtained from a first-trimester interview. Discrete-time hazard models were used, candidate confounders were assessed, and the following variables were included in the model: study site, maternal age, gravidity, marital status, education, race/ethnicity, smoking, and use of progesterone in early pregnancy. Approximately 95% of participants reported use of vitamins during early pregnancy. A total of 524 women had a miscarriage. In the final adjusted model, any use of vitamins during pregnancy was associated with decreased odds of miscarriage (odds ratio = 0.43, 95% confidence interval: 0.30, 0.60) in comparison with no exposure. These results should be viewed in the context of a potentially preventive biologic mechanism mitigated by possible confounding by healthy behaviors and practices that are also associated with vitamin supplement use during pregnancy.

    Appropriate nutrition in pregnancy is fundamental for maternal and fetal health, and the long-term physiological wellbeing of the offspring. We aimed to determine whether a sample of pregnant women met the national guidelines for healthy eating during pregnancy, and to examine if compliance differs when analysed by Body Mass Index (BMI) category. Subjects completed a 24-hr dietary recall, and had their BMI calculated. The mean age was 27.8 years. The mean BMI was 25.1 kg\\/m2, with 32 (31.7%) subjects overweight and 14 (13.9%) obese based on BMI category. Although the majority of subjects thought that they had a healthy diet, less than half met the recommended guidelines for each individual food group with achievement of the dairy group being particularly low. Achievement of food group recommendations was not influenced by BMI category. Public health messages on healthy eating guidelines need to be clearly communicated to pregnant women.

    Objective To explore the effects on macaques' menstrual recovery after terminating early pregnancy by focused ultrasound beams (FUB)Methods FUB was used to terminate early pregnancy in 5 macaques with gestation duration ranging from 37-66 d. Two circles after the recovery of menstruation, color Doppler flow imaging (CDFI) and magnetic resonance imaging (MRI) were used to estimate the shape, size and blood flow of uterus, and pathological examinations were performed to check against any lesions to uterine endometrium and ovary.Results Forty days after FUB abortion, menstruation recovered and the volume and duration of each macaque's menstruation were not changed compared with those before gestation. CDFI and MRI suggested that the siz.e and shape of uterus were normal.The endometrial line was clear and no lesions were found in adjacent organs.Conclusion FUB termination of early pregnancy in macaques did not damage their ovarian tissue and had no influence on subsequent menstrual recovery.

    This study aimed to determine the association between early pregnancy loss and serum ischemia-modified albumin (IMA) concentrations. Serum samples of 180 women that included healthy pregnant women, women admitted for termination of pregnancy due to the absence of fetal cardiac activity or absence of fetal pole on ultrasonographic examination, and healthy non-pregnant women attending for gynecological examination. Each group included 60 patients. Serum concentrations of IMA were compared among the groups, and the correlations with patients' age, gravidity, BMI, gestational age and total serum albumin concentrations were calculated. When the groups were compared with respect to IMA concentrations, the group with early pregnancy loss was found to have significantly higher IMA concentrations (p 163 ng/mL had a sensitivity of 75%, specificity of 55% to discriminate between healthy pregnant patients and patients with early pregnancy loss in first trimester. Our findings support the theory that possible oxidative stress, a more hypoxic environment and defective placentation lead to increased serum IMA concentrations. These findings may help to shed light on the complicated pathogenesis of early pregnancy loss.

    Vaginal bleeding is a common event in early pregnancy, with 20-40% of pregnancies affected. Prompt diagnosis and management of bleeding is important, both to reduce morbidity and to avoid excessive emotional distress. This was a prospective study of an educational programme aimed at Obstetrics and Gynaecology BST trainees in the National Maternity Hospital, Dublin. The educational programme consisted of didactic lectures, and simulation and practical sessions. A questionnaire reviewing early pregnancy complications was used to assess participant knowledge. Six trainees participated in the programme, with five (83%) answering the questionnaire. The pre-education questionnaire showed a generally poor level of knowledge of early pregnancy complications with 8\\/50 (16%) questions answered correctly. Following the educational intervention there was a statistically significant increase in participant knowledge with 45\\/50 (90%) questions answered correctly. A significant increase in participant knowledge of early pregnancy complications followed our multifaceted educational programme. Study limitations exist, however we have shown the potential value of our educational programme.

    Full Text Available The first cases of mother to child transmission of human immunodeficiency virus (HIV were described more than two decades ago and since then several thousands more have been reported in western countries. In the early 1980s the majority of perinatally acquired HIV children did not survive beyond childhood. However combined antiretroviral therapy (ART for perinatally HIV-acquired children has prolonged their survival and in the past 2 decades, many have reached adulthood. As the perinatally HIV-infected females become sexually active, they are in turn at risk for pregnancy and of transmitting HIV infection to their children. A considerable proportion of this population appears to engage in unprotected sexual intercourse leading to teenage pregnancies, STDs, and abnormal cervical cytology despite frequent contact with HIV health care providers and clinics. Currently there is a paucity of data regarding pregnancy and neonatal outcomes in HIV perinatally infected women. As increasing number of pregnancies will occur among this population we must continue to monitor and focus on their reproductive health issues to improve perinatal and long-term maternal outcomes. This paper will summarize our current knowledge about reproductive health issues and identify areas for future inquiry.

    Thyroid hormones are important for normal fetal development. Maternal hypothyroidism during early pregnancy is associated with impaired neuropsychological development of children and other adverse outcomes. The primary aim of this prospective study was to determine whether thyroxine-treated pregnant women with hypothyroidism are adequately thyroxine substituted in early pregnancy. A secondary aim was to determine if fetal loss differed between females with thyrotropin (TSH) values within and outside the reference range at their first TSH test, scheduled for 1-2 weeks after verification of pregnancy. This was a prospective open-labeled study. During the years 1997-2002, 119 consecutive pregnancies in 101 females with thyroid diseases were followed at the Department of Endocrinology, Malmö University Hospital. At the first visit, 63 patients, median age 30 years (range 17-45 years), were on thyroxine substitution therapy for hypothyroidism. In these patients 83% were in their first trimester at the time of the initial test. Of the 63 patients on thyroxine substitution for hypothyroidism 32 (51%; Group A) patients had serum TSH values within the reference range at their initial test and 31 (49%; Group B) had serum TSH values outside the reference range. Twelve (19%) had TSH values of 4.0 mIU=l. The fetal loss was 2 of 32 (6%) in Group A compared to 9 of 31 (29%) in Group B ( p pregnant women on thyroxine substitution, serum TSH values were outside the reference range when first tested, generally in the first trimester. Fetal loss was significantly greater in pregnant women with abnormal TSH values compared to those with normal TSH values. Thyroid function in pregnant women on thyroxine substitution should be monitored early in pregnancy and carefully followed during pregnancy. The thyroxine dose should be increased as needed early in pregnancy to avoid hypothyroidism.

    Human chorionic gonadotropin (hCG) as the most important factor to controlled implantation is one of the early embryonic signals in primates that is secreted by the embryo before its implantation. This study was designed to assess the effects of intrauterine injection of hCG before the embryo transfer in an in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) cycle on pregnancy rate in infertile patients. This randomized study was done on 100 infertile patients in two groups: intervention group received injection of 700 IU of intrauterine hCG 10 min before embryo transfer and control group did not receive hCG. The pregnancy rate was tested 2 weeks after embryo transfer, and if the pregnancy test was positive, a transvaginal ultrasound was performed 3 weeks later to search for signs of pregnancy, such as the presence of a gestational sac, embryo, and fetal heart rate, and confirmed as successful pregnancy. Pregnancy test was positive in 13 (28.6%) of 46 patients in hCG group and in control group was positive in 6 (12.5%) of 48 patients. The pregnancy rate between hCG group and control group was not significantly different (P = 0.54). The pregnancy rate in hCG group with IVF fertilization was 20.8% and in their controls was 7.4% (P = 0.51). The pregnancy rate in hCG group with ICSI fertilization was 36.4% and in their controls was 19% (P = 0.16). The intrauterine injection of 700 IU of hCG before embryo transfer improved pregnancy rate compared to control group but was not significantly different.

    Full Text Available Objective: to assess the relationship of corpus luteum morphology and vascularity by 3 dimensional power Doppler ultrasound and the pregnancy outcome in early pregnancy. Design: prospective observational cohort study. Setting: Zagazig University Hospital. Materials and methods: this is a prospective observational cohort study of thirty six pregnant patients examined by two dimensional and three dimensional transvaginal sonography for corpus luteum volume, echostructure and corpus luteum vascularization index in the period after documentation of fetal heart activity and nine weeks. Results: there were 36 study women, ultrasound morphologic features of corpus luteum: volume ranged from 0.91 to 42.8 ml with median of 6.85, vascularization index ranged from 0.05 to 23.8 with a median of 6.85, echostructure was cystic in 12 women (33.3%, hemorrhagic in 18 (50% and solid in 6 women (16.7%. The relation between CL volume and pregnancy outcome was significant (p-value was 0.02, being smaller in group of missed abortion. The relation between CL VI and pregnancy outcome was non significant (p-value was 0.229. The relation between CL echostructure and pregnancy outcome was highly significant (p-value was 0.009. The prognosis was worst in group of solid echostructure. Conclusion: the corpus luteum volume and echostructure assessed by 3D power Doppler ultrasound have statistical relationship with the early pregnancy outcome.

    Pregnancy is a unique period to quit smoking and alcohol consumption and although motivated, not all women succeed at this. We investigated the associations of personality with continued smoking and continued alcohol consumption during early pregnancy. In addition, we studied whether antenatal anxiety and depressive symptoms can explain these associations. Two antenatal measurements from the population-based Pregnancy Anxiety and Depression cohort study were used. Pregnant women in their first trimester were recruited via midwifery practices and hospitals. We analyzed a sample of women who continued (n=101) or quit smoking (n=254), and a sample of women who continued (n=110) or quit alcohol consumption (n=1230). Measures included questions about smoking, alcohol consumption, the NEO-Five Factor Inventory (personality), the State Trait Anxiety Inventory, and the Edinburgh Postnatal Depression Scale. We found associations between continued alcohol consumption and higher levels of openness to experience, and lower levels of conscientiousness (psmoking emerged. This study contributes to the limited literature on personality differences between women who continue and quit smoking and alcohol consumption during early pregnancy. General population studies have not confirmed the association between openness to experience and alcohol consumption which implies that pregnancy is indeed a unique period. Increased insight in how personality influences continued smoking and alcohol consumption during pregnancy can help health professionals to improve lifestyle interventions targeted at pregnant women.

    Maternal fish consumption during pregnancy may affect children's asthma risk by modulating early-life immune development. Type of fish intake may be important because of differences in fatty acid content. To test this hypothesis, we conducted a nested case-control study, selecting subjects from the Children's Health Study, a population-based study of school-aged children in southern California. Cases had physician-diagnosed asthma and controls were asthma-free by age 5 years. Mothers or guardians provided information on fish consumption during pregnancy in telephone interviews. We computed odds ratio (OR) and 95% confidence interval (CI) by using conditional logistic regression models that accounted for the sampling. In children born to mothers with a history of asthma, the OR of asthma was 0.20 (95% CI = 0.06-0.65) when mothers ate oily fish at least monthly during pregnancy compared with no consumption (p(trend) = 0.006). Maternal oily fish consumption during pregnancy did not benefit children of non-asthmatic mothers. In contrast, fish stick (a source of trans-fats) consumption during pregnancy increased asthma risk in children (OR = 2.04; 95% CI = 1.18-3.51). Our results suggest that maternal oily fish intake during pregnancy may protect offspring from asthma; however, eating fish sticks during pregnancy may increase asthma risk in children.

    Female sexual function is negatively influenced by pregnancy due to the physical and emotional changes. Although the most significant effect is seen in the third trimester of pregnancy, a considerable decrease in the frequency of intercourse and sexual desire in the first trimester has also been shown. To investigate the factors that affect sexuality in early pregnancy and the impact of awareness of pregnancy on female sexual function in the first trimester of pregnancy using two self-reported questionnaires. In this cross-sectional study, 130 healthy, married pregnant women who were admitted to the gynecology clinic between the 4th and 10th week of gestation were asked to complete a self-administered questionnaire and the female sexual function index (FSFI). The factors associated with FSFI score and monthly sexual activity frequency in the first trimester, as well as the differences in sexual activity frequency and FSFI scores between the women who were previously aware of their pregnancy and those who were yet unaware of their pregnancy. Women who were unaware of their pregnancy had significantly higher coitus frequency in comparison with the aware group (P = 0.002). Total FSFI score was 21.99 ± 8.13 in the aware group and 24.66 ± 3.76 in the unaware group (P = 0.02). None of the obstetric and sociodemographic variables had an influence on desire and pain scores. Arousal, lubrication, and satisfaction scores were adversely affected by awareness of pregnancy. Orgasm scores were influenced negatively by awareness and positively by love marriage; however, in multivariate linear regression analysis none of these were defined as independent factor for orgasm scores. Overall FSFI scores and monthly frequency of sexual activity were only affected by awareness. The results of this study suggest that in early gestation, awareness of pregnancy is associated with lower female sexual function. Furthermore, obstetric and sociodemographic factors seem to be

    Full Text Available Background: Bacteriuria is a major risk factor for developing symptomatic urinary tract infection which is associated with significant maternal and fetal risks. Various studies have put a prevalence of asymptomatic bacteriuria between 2-10% in pregnancy. Maternal and fetal complications like gestational hypertension, anaemia, premature delivery, IUGR, and low birth weight are commonly associated with pyelonephritis which occurs as a result of undiagnosed or inadequately treated infections of the urinary tract. The primary objective was to find out the prevalence of asymptomatic bacteriuria in pregnancies less than 28 weeks gestation in our hospital and to study the various adverse pregnancy outcomes in the study group. Methods: This was a cross sectional study done over a period of 12 months at this tertiary care centre in Government sector in Trivandrum, Kerala. A sample size was calculated statistically and 400 women with gestational age less than 28 weeks attending the outpatient department were included in this study. A structured proforma, urine microscopy and urine culture and sensitivity were the study tools. Results: Prevalence of asymptomatic bacteriuria in our study population was 8.25%. Commonest pathogen isolated was E.coli in 57.14% cases. Maternal morbidity was higher in women with asymptomatic bacteriuria (24.2% than those without (12.5%. Fetal morbidity in women with asymptomatic bacteriuria was 24% whereas it was 12.5% in those without it. Preterm labour, preeclampsia and prematurity were the common morbidities noted. Conclusions: Since pregnant women with asymptomatic bacteriuria were at an increased risk of adverse maternal and fetal outcome, routine screening for asymptomatic bacteriuria preferably in the first trimester is highly recommended.

    Environmental and occupational exposure to endocrine disrupting chemicals (EDCs) is a major threat to female reproductive health. Bisphenol A (BPA), an environmental toxicant that is commonly found in polycarbonate plastics and epoxy resins, has received much attention due to its estrogenic activity and high risk of chronic exposure in human. Whereas BPA has been linked to infertility and recurrent miscarriage in women, the impact of its exposure on uterine function during early pregnancy remains unclear. In a recent publication in Endocrinology, we demonstrated that prolonged exposure to an environmental relevant dose of BPA disrupts progesterone receptor-regulated uterine functions, thus affecting uterine receptivity for embryo implantation and decidua morphogenesis, two critical events for establishment and maintenance of early pregnancy. In particular we reported a marked impairment of progesterone receptor (PGR) expression and its downstream effector HAND2 in the uterine stromal cells in response to chronic BPA exposure. In an earlier study we have shown that HAND2 controls embryo implantation by repressing fibroblast growth factor (FGF) expression and the MAP kinase signaling pathway, thus inhibiting epithelial proliferation. Interestingly we observed that downregulation of PGR and HAND2 expression in uterine stroma upon BPA exposure was associated with an enhanced activation of FGFR and MAPK signaling, aberrant proliferation, and lack of uterine receptivity in the epithelium. In addition, the proliferation and differentiation of endometrial stromal cells to decidual cells, an event critical for the maintenance of early pregnancy, was severely compromised in response to BPA. This research highlight will provide an overview of our findings and discuss the potential mechanisms by which chronic BPA impairs PGR-HAND2 pathway and adversely affects implantation and the establishment of pregnancy.

    Early diagnosis of ectopic pregnancy (EP) is important due to life-threatening consequences in the first trimester of pregnancy. In this study we aimed to investigate the role of adenosine deaminase (ADA) activity in the prediction of EP. Forty-one patients with unruptured ectopic pregnancy comprised the case group and forty-two first trimester pregnant women with shown foetal heart beating in ultrasound comprised the control group. The mean ADA level in EP (10.9 ± 3.0 IU/L) was higher than that in control group (9.2 ± 3.6 IU/L) (p = 0.018). Receiver operating characteristics or ROC curve identified ADA value of 10.95 IU/L as optimal threshold for the prediction of EP with 56% sensitivity and 67% specificity. High ADA levels are valuable in the early diagnosis of EP. However more comprehensive studies are required.

    INTRODUCTION: Misoprostol can be used in the prevention of gastric ulcer in treatment with diclofenac and is used in rheumatic diseases. Since misoprostol causes contractions of the uterus, it can also be used to induce abortions when administrated vaginally. The aim of the study was to investigate...... if early pregnancy exposure to oral diclofenac/misoprostol was associated with miscarriage. METHOD: We conducted a nationwide cohort study identifying all registered pregnancies in Denmark from 1997 to 2011. All births were identified using the Medical Birth Registry, and all records of induced abortion...... and miscarriage were from the National Hospital Register. Data on drug use were from the National Prescription Register. Cox proportional hazard regression models were used to calculate the hazard of miscarriage in women exposed to diclofenac/misoprostol in early pregnancy. RESULT: We identified 1...

Petropoulos et al. now provide an extensive transcriptome analysis of a large number of human pre-implantation embryos at single-cell resolution, revealing previously unrecognized features unique to early human development.

  7. Docosahexaenoic Acid Supplementation Early in Pregnancy May Prevent Deep Placentation Disorders

    Full Text Available Uteroplacental ischemia may cause preterm birth, either due to preterm labor, preterm premature rupture of membranes, or medical indication (in the presence of preeclampsia or fetal growth restriction. Uteroplacental ischemia is the product of defective deep placentation, a failure of invasion, and transformation of the spiral arteries by the trophoblast. The failure of normal placentation generates a series of clinical abnormalities nowadays called “deep placentation disorders”; they include preeclampsia, fetal growth restriction, preterm labor, preterm premature rupture of membranes, in utero fetal death, and placental abruption. Early reports suggested that a LC-PUFAs (long chain polyunsaturated fatty acids rich diet reduces the incidence of deep placentation disorders. Recent randomized controlled trials are inconsistent to show the benefit of docosahexaenoic acid (DHA supplementation during pregnancy to prevent deep placentation disorders, but most of them showed that DHA supplementation was associated with lower risk of early preterm birth. We postulate that DHA supplementation, early in pregnancy, may reduce the incidence of deep placentation disorders. If our hypothesis is correct, DHA supplementation, early in pregnancy, will become a safe and effective strategy for primary prevention of highly relevant pregnancy diseases, such as preterm birth, preeclampsia, and fetal growth restriction.

    2015-10-01

    Full Text Available Antihistamines are a group of medications which can inhibit various histaminic actions at one of two histamine receptors (H1 or H2. H1 receptor antagonists are used for the relief of allergic dermatological and nondermatological conditions. We will review classes of antihistamines (H1 antagonists and the relationship between specific antihistamines and specific birth defects. Although many findings provide reassurance about the relative safety of many antihistamine drugs and that any malformation reported is most probably caused by chance, studies are still required to assure fetal safety. As pruritus is sometimes troublesome for pregnant women topical medications like emollients should be tried first in the first trimester of pregnancy. Also pregnant women should be advised to consult their health care provider before taking any medication.

  17. [Female genital mutilations, forced marriages, and early pregnancies].

    Female genital mutilations, as well as forcible childhood marriage and their correlate adolescent pregnancies are traditional practices which, not only violate the dignity, but also jeopardize the health, and even the life, of women and their children. The complications of genital mutilations are frequent for a number of reasons: the fact that the clitoris is highly vascularized, the nature of the mutilations, excision or infibulation, and the poor conditions of hygiene. The short term complications are pain, hemorrhage, shock, and urinary retention. Medium term complications include gangrene, septicemia, tetanus, pelvic inflammatory disease, HIV/AIDS, and hepatitis B or C infections. Serious sequelae may occur, including infertility and gynecologic disorders, and sexual life is invariably altered. The main obstetrical complications of genital mutilations are genital lacerations involving the labia minor and the perineum, which can lead to hemorrhage and sequelae such as urinary or anal incontinence, recto-vaginal and vesico-vaginal fistulas. The role of doctors, which is delicate because these customs are entrenched, is to detect genital mutilations, repair them and prevent them, by participating in health education programs. The consequences of forcible childhood marriage are serious, besides the fact that this is a disguised form of rape. The obstetrical risks favored by the underdevelopment of the uterus and the pelvis, include uterine rupture, preeclampsia and eclampsia, and obstetrical hemorrhage. The fetus/neonate are jeopardized by these complications, which can result in perinatal asphyxia and death, as well as the high rates of intrauterine growth retardation and preterm delivery. The impact of genital mutilations on delivery are compounded in childhood pregnancies for anatomical reasons, but also because these adolescents or children are extremely vulnerable and have poor access to perinatal care. In France, as well as in Africa, non-governmental and

    The body of first-time pregnant women is affected in many ways, and the women may not know what to expect. Conversations between women and healthcare personnel about women's bodily experience in early pregnancy can contribute to increased body knowledge, which may have a positive impact in later stages of their pregnancy and in relation to delivery. The aim of the study was to describe first-time pregnant women's experiences of their body in early pregnancy (pregnancy weeks 10-14). Twelve women were asked to draw pictures and answer questions freely about their experiences of their first pregnant body. Hermeneutical text interpretation was used to obtain an overall view of the experiences. A main theme emerged: 'the body is connected to the cycle of life'. This theme comprised five subthemes: 'bodily longing and a sense of ambivalence', 'being doubtful', 'welcoming changes in body and mind', 'feeling inner strength and struggle to find strength' and 'accepting a different body and mind'. This main theme and the subthemes were further interpreted and were understood as an experience of 'me and my body'. The body reminded the women to take care of it and gave rise to positive thoughts. When the body exhibited uncomfortable reactions and sensations, these were taken as evidence of pregnancy, which was also seen positive but it also triggered a sense of dissatisfaction with the body and a feeling of it becoming alien. © 2016 Nordic College of Caring Science.

    This study compared early plasma levels of plasminogen activator inhibitor-1 (PAI-1) in normal pregnancy and preeclampsia and determined its relationship with disease severity. This was a prospective cohort study of 195 normotensive, aproteinuric pregnant women without prior history of gestational hypertension. The women were attending the Antenatal Clinic at The Lagos University Teaching Hospital and were within 24 weeks gestation at recruitment. The outcome measures were PAI-1, systolic blood pressure (SBP), diastolic blood pressure (DBP), and significant proteinuria. The endpoint of the study was the development of preeclampsia. The diagnosis of preeclampsia was made by the attending Obstetrician. The data were analyzed using the IBM SPSS statistical software. Statistical significance was set at P women who later developed preeclampsia compared to those who had a normal pregnancy (P women who later developed preeclampsia, PAI-1 had an inverse relationship with gestational age (r = 0.878) whereas in normal pregnancy, PAI-1 and gestational age had a direct relationship (r = 0.017). Second trimester systolic and DBP values were also significantly higher in the women who later developed preeclampsia compared to normal pregnancy, P = 0.007 and 0.004, respectively. There was, however, no correlation between PAI-1 values and SBP, DBP and proteinuria in the women who developed preeclampsia. Plasma levels of PAI-1 are increased early in pregnancies complicated by preeclampsia, but the lack of correlation of this marker with disease severity may limit its clinical utility.

    This study investigated whether a 27-day period of nutrition at half-maintenance during early pregnancy (up to Day 14) could alter maternal endocrine responses. Forty-six ewes were fed all or half of their maintenance requirements and slaughtered on Day 14 of the oestrous cycle or pregnancy. We used real time RT-PCR to study gene expression of growth hormone receptor (GHR) and leptin in adipose tissue and GHR, GHR1A and of the insulin-like growth factor I (IGF-I) in the liver. Blood profiles of metabolites and metabolic hormones were also determined. Throughout the experiment, underfed animals presented lower body weight and body condition, greater plasma concentrations of non-esterified fatty acids (NEFA), and lower plasma concentrations of leptin, compared to adequately fed animals. Undernutrition affected the patterns of gene expression in adipose and hepatic tissues, and the responses differed between pregnant and non-pregnant ewes. In adequately fed ewes, pregnancy up-regulated leptin mRNA expression in adipose tissue, a response that was impaired in underfed ewes. The hepatic expression of IGF-I mRNA was increased by pregnancy in underfed animals while no effect was observed in adequately fed ewes. It remains to be determined whether the changes in the endocrine milieu are paralleled by modifications in uterine gene expression that could alter the environment of the embryo during early pregnancy.

    The stage-specific expression of functional proteins within the endometrium, and their regulation by conceptus-derived signals, are crucial for conceptus development and successful establishment of pregnancy. Accurate knowledge of endometrium-conceptus interactions is key for the development of effective strategies to improve conceptus implantation rates both following natural conception and/or assisted reproductive technologies. The unilateral pregnant ewe provides a powerful experimental model for the study of endometrial function in the presence or absence of conceptuses during the peri-implantation period. Two-dimensional gel electrophoresis and mass spectrometry-based proteomics were used to compare and identify differentially expressed proteins in caruncular endometrium collected from the gravid uterine horns and the non-gravid uterine horns at the time of conceptus attachment (day 16 of pregnancy) and early post-implantation period (day 20 of pregnancy). Fifty seven protein spots were up-regulated in the gravid horn at day 16 of pregnancy and twenty seven protein spots were up-regulated in the gravid horn at day 20 of pregnancy. Sixteen proteins with different functions such as protein metabolism, cholesterol and ion transport and cell adhesion were identified. In conclusion, the use of the unilaterally pregnant ewe model provides evidence that the early implantation and post-implanting conceptus-derived signals up-regulate caruncle endometrial proteins, including carbonic anhydrase 2 (CA-II) and apolipoprotein A-1 (APOA1) and down-regulate caruncle endometrial proteins, including adenosylhomocysteinase (AHCY) and heat shock 60kDa protein 1 (HSP60). These regulated proteins are likely involved in providing a suitable intra-uterine environment required for conceptus attachment, implantation, early post-implantation development and the successful establishment of pregnancy in sheep.

    2008-02-01

    Past studies of the source of estrogens secreted during maternal recognition of pregnancy in pigs have focused on embryonic rather than uterine origin of these steroids. The present study documents: (1) the expression of the gene CYP 17, encoding cytochrome P450 17alpha-hydroxylase/C(17-20) lyase and (2) the synthesis and secretion of estradiol-17 beta (E(2)) in endometrial and myometrial tissues in gilts. The expression of CYP 17 gene was shown in porcine endometrium and myometrium. Basal endometrial secretion of E(2) was higher in pregnant gilts than in cyclic gilts (days 14-16). The myometrium secreted more E(2) during the expected time of luteolysis compared to early pregnancy. Basal secretion of E(2) during pregnancy was higher from the endometrium than from the myometrium. Conversely, during luteolysis E(2) secretion was higher from the myometrium and lower from the endometrium. In pregnant and cyclic gilts (days 14-16), progesterone (P(4), 10(-5)M) in vitro significantly increased E(2) secretion regardless of reproductive status. Oxytocin (OT, 10(-7)M) had no influence on E(2) secretion and did not change the stimulatory effect of P(4) in both tissues examined. In conclusions: (1) the CYP 17 gene transcript is present in porcine endometrium and myometrium; (2) porcine endometrium and myometrium release E(2) in vitro; (3) the endometrium releases more E(2) than the myometrium during early pregnancy; (4) the myometrium releases E(2) mainly during luteolysis; (5) the endometrium and myometrium can increase E(2) release in vitro if substrate (P(4)) is provided during early pregnancy and luteolysis. These data suggest active estrogen production by the myometrium and endometrium as an alternative source for this signal for recognition of pregnancy in the pig.

    Full Text Available BACKGROUND Genetic diseases are one of the major causes of hospital admissions due to disability and mortality particularly among children (1:5 children of hospital admission either partially/completely as distribution of genetic diseases is not related to socioeconomic background, which implies that developing world has a large number of genetic diseases largely left uncared for, i.e. overall incidence of foetal/neonatal loss due to genetic/genetic environmental causes are as follows: 1:50 newborns have major congenital abnormality, 1:100 have a unifactorial disorder, 1:200 have a major chromosomal abnormality before birth. Diagnosis of chromosomal anomalies in foetus is one of the most important challenges in modern perinatology as invasive or noninvasive methods. The aim of the study is to review on cytogenetic evaluation of CVS obtained (transcervically during first trimester of pregnancy by direct karyotyping of tissue. MATERIALS AND METHODS This study was conducted in 2001 in Department of Anatomy along with Obstetrics and Gynaecology Department, LNJP Hospital. 37 healthy cases with 6-12 weeks of gestational age coming for medical termination of pregnancy were included in the study. After written informed consent for procedure, ultrasound-guided transcervical chorionic villus sampling was done (Brambati’s method. Tissue procured was then processed for direct karyotyping and studied. Metaphase spreads were photographed and karyotypes prepared and studied. RESULTS Out of 37 pregnant females, 30 samples were successfully prepared and processed by Direct method out of which 23 were normal female (46, XX and 7 were normal male (46, XY. No normal anomaly was detected. Best biopsies were obtained with 8-12 weeks gestation. G Banding could not be performed as chromosome obtained were found to be resistant to banding. CONCLUSIONS To summarise chromosome preparations obtained from CVS by Direct method has advantage of providing sufficient number

    Plasma volume expansion has been associated with fetal growth. Our objective was to examine the associations between maternal nutritional status in early pregnancy and extracellular water (ECW), total body water (TBW), and percentage plasma volume change across pregnancy. In a subsample of 377 pregnant women participating in a cluster-randomized trial of micronutrient supplementation, hemoglobin, hematocrit, and multi-frequency bioelectrical impedance were measured at ~10, 20, and 32 wk of gestation. In early pregnancy, women were short (mean ± SD, 148.9 ± 5.3 cm) and thin (19.5 ± 2.5 kg/m(2)). In mixed-effects multiple regression models, a 1-unit higher BMI at ~10 wk was associated with higher ECW and TBW (0.27 and 0.66 kg per kg/m(2), respectively; P pregnancy BMI was negatively associated with gains in ECW and TBW (-0.06 and -0.14 kg per kg/m(2), respectively; P pregnancy have lower ECW and TBW in early, mid, and late pregnancy and lower late pregnancy plasma volume expansion, potentially increasing risk of fetal growth restriction.

    We report a case of painless thyroiditis detected during the first trimester of pregnancy. A 29-year-old Japanese woman was hospitalized because of thyrotoxicosis and she was confirmed to be pregnant. The gestational age was 4 weeks. Blood examinations revealed negative TSH receptor antibodies, however, we started potassium iodide because we were unable to rule out Graves' disease. Thyroid hormone levels were normalized in 3 weeks and remained low even after discontinuation of medication. She received replacement therapy with levothyroxine sodium hydrate till 3 months after delivery. Painless thyroiditis can be one of the differential diagnoses of thyrotoxicosis in a very early stage of pregnancy.

    Cervico-isthmic pregnancy is a rare and potentially life-threatening form of ectopic gestation in which the blastocyst implants in the uterine cervico-isthmus between the histological and anatomical internal os, followed by subsequent extension to the lower uterine segment. Early diagnosis may allow a conservative therapeutic approach that avoids catastrophic hemorrhage requiring hysterectomy. Here we report the case of a 43-year-old primigravida woman whose cervico-isthmic pregnancy complicated by massive hematometra was diagnosed at 6 weeks gestation by multimodal imaging and successfully treated by hysteroscopic resection, securing adequate hemostasis, after transcatheter arterial chemoembolization.

    The paper is a report of ultrasonic examinations of IUD positions in women who became pregnant with IUD in situ. 61 pregnant women aged 23 to 41 wearing stainless steel single ring IUD were examined between 1983 and 1985. The duration between the IUD insertion and pregnancy of these women ranged from one month to 5 years with 67.2% under 1 year. This indicated that the first year after IUD insertion is a critical period for method failure. Extra care should be taken in the follow-up of insertion. Among the cases studied, the IUD position of 42 women was below the embryo in the uterine cavity, including some around the cervix. The position change of IUD apparently lost its contraceptive effect. The declined position of IUD in the uterus could be associated with the skill of inserter, and the compatibility of the shape and the size of IUD with the uterine cavity. It was suggested that both the length and width of uterine cavity should be measured before the insertion, and IUD's of all sizes should be made available in the clinics where the insertions are conducted. IUD different shapes should also be kept too fit those women with irregularly shaped uteri.

    We explored the effectiveness, safety, and feasibility of focused ultrasound in terminating undesired pregnancy. A high-intensity focused ultrasound therapeutic unit was employed to terminate early pregnancies in rhesus macaques. B-mode ultrasound incorporated within the system was used to locate and study the gestational sacs of 6 rhesus macaques with gestation ages of 37 to 66 days, and varying modes of ultrasound exposure were adopted in the termination of the early pregnancies of the rhesus macaques. After focused ultrasound exposure, B-mode ultrasound of the gestational sacs showed significant lethal changes. Of the 6 rhesus macaques, 5 underwent complete abortions whereas 1 rhesus macaque underwent an incomplete abortion. The rhesus macaques resumed their menstrual cycles 50 days after focused-ultrasound treatment. The results suggested that focused ultrasound could be safe, feasible, and effective in terminating early pregnancies in rhesus macaques. As a novel physical method, it may be a promising ablation for a potentially clinical application. Copyright © 2012 World Federation for Ultrasound in Medicine & Biology. Published by Elsevier Inc.

  9. Clarithromycin in early pregnancy and the risk of miscarriage and malformation: a register based nationwide cohort study.

    Directory of Open Access Journals (Sweden)

    Jon Trærup Andersen

    Full Text Available BACKGROUND: The antibiotic clarithromycin has been associated with fetal loss in animals and a study has found a doubling in the frequency of miscarriages among women using clarithromycin in pregnancy. The aim of the study was to investigate whether clarithromycin use in early pregnancy was associated with an increased risk for miscarriages and major malformations. METHODS: We conducted a nationwide cohort study including all women in Denmark with a known conception between 1997 and 2007. The Fertility Database was used to identify all women giving birth and the National Hospital Register was used to identify all women with a record of miscarriage or induced abortion. Prescription data was obtained from the National Prescription Register. The primary outcome was the number of miscarriages and offspring with major congenital malformations among users of clarithromycin compared to non-users. RESULTS: We identified 931 504 pregnancies (705 837 live births, 77 553 miscarriages, and 148 114 induced abortions. 401 women redeemed a prescription of clarithromycin in the first trimester of which 40 (10.0% experienced a miscarriage and among the live born nine (3.6% had offspring with malformations. The hazard ratio (HR of having a miscarriage after exposure to clarithromycin was 1.56 (CI95% 1.14-2.13. There was no increased hazard of having a miscarriage when being exposed to penicillin or erythromycin. There was no increased prevalence (OR = 1.03 (CI95% 0.52-2.00 of having offspring with malformations after exposure to clarithromycin. CONCLUSIONS: We found an increased hazard of miscarriage but no increased prevalance of having offspring with malformations among women redeeming a prescription of clarithromycin in early pregnancy. This is supported by previous studies in animals and humans. However, further research is required to explore the possible effect of treatment indication on the associations found.

    Early intermittent cortical activity is thought to play a crucial role in the growth of neuronal network development, and large scale brain networks are known to provide the basis for higher brain functions. Yet, the early development of the large scale synchrony in cortical activations is unknown. Here, we tested the hypothesis that the early intermittent cortical activations seen in the human scalp EEG show a clear developmental course during the last trimester of pregnancy, the period of intensive growth of cortico-cortical connections. We recorded scalp EEG from altogether 22 premature infants at post-menstrual age between 30 and 44 weeks, and the early cortical synchrony was quantified using recently introduced activation synchrony index (ASI). The developmental correlations of ASI were computed for individual EEG signals as well as anatomically and mathematically defined spatial subgroups. We report two main findings. First, we observed a robust and statistically significant increase in ASI in all cortical areas. Second, there were significant spatial gradients in the synchrony in fronto-occipital and left-to-right directions. These findings provide evidence that early cortical activity is increasingly synchronized across the neocortex. The ASI-based metrics introduced in our work allow direct translational comparison to in vivo animal models, as well as hold promise for implementation as a functional developmental biomarker in future research on human neonates.

    We previously reported that hypergravity exposure affects food intake and mass gain during pregnancy. In the present study, we explored the hypothesis that changes in maternal body mass in hypergravity-exposed pregnant rat dams affect pregnancy outcome and early offspring development. Furthermore, we hypothesized that the changes observed at 1.5G will be magnified at higher gravity and by exposure during critical developmental periods. To test this hypothesis, we compared maternal body mass gain, food consumption, birth outcome and early offspring development between Sprague Dawley rat dams exposed to graded (1.5 1.75G) chronic hypergravity (HG) or rotation (rotational control, RC) on a 24-ft centrifuge for 22.5 h starting on gestational day (G) 10 with dams housed under identical conditions but not exposed to hypergravity (SC). We also compared maternal body mass, food consumption, birth outcome and early offspring development between rat dams exposed to 1.65G during different stages of pregnancy and nursing. Exposure to hypergravity resulted in transient loss in body mass and prolonged decrease in food consumption in HG dams, but the changes observed at 1.5G were not magnified at 1.65G or 1.75G. On the other hand RC dams gained more mass and consumed more food than SC dams. Exposure to hypergravity also affected pregnancy outcome as evidenced by decreased litter size, lowered neonatal mass at birth, and higher neonatal mortality; pregnancy outcome was not affected in RC dams. Neonatal changes evidenced by impaired righting response observed at 1.5G was magnified at higher gravity and was dependent on the period of hypergravity exposure. On the other hand, righting response was improved in RC neonates. Hypergravity exposure during early postpartum affected the food consumption of nursing mothers and affected early survival of their offspring. The changes observed in dams and neonates appear to be due to hypergravity exposure since animals exposed to the rotation

    Using a longitudinal study design, we investigated changes in maternal core temperature and ambient temperatures before and after a localized cooling procedure to the right hand. Fifteen pregnant women participated. The experiments were sequentially performed for 21 month periods on each subject: from the 8th week of gestation to 1 year after delivery on seven separate occasions (gestational weeks 8, 16, 26, 36 and 12, 24, 52 weeks post-partum). The experiments were conducted in a climactic chamber, allowing ambient temperature adjustment to each subjects' thermoneutral zone determined using Doppler ultrasound of the digital artery. Maternal core temperature decreased from 37.1 °C (week 8) towards term, reaching a nadir (36.4 °C) at 12 weeks post-partum (P temperature required to reach the thermoneutral zone changed significantly from 26.5 °C (week 8) falling to its lowest point: 23.0 °C (week 36) (P temperature is highest in the first trimester but falls during pregnancy to a nadir 3 months post-partum. The ambient temperature required to reach the thermoneutral zone was 4 °C lower at 36 weeks of gestation compared with early pregnancy and late post-partum. Human temperature regulation is altered in pregnancy and for at least 3 months post-partum.

  18. Ambulatory blood pressure monitoring for the early identification of hypertension in pregnancy.

    Ayala, Diana E; Hermida, Ramón C

    2013-03-01

    Gestational hypertension and preeclampsia are major contributors to perinatal morbidity and mortality. The diagnosis of gestational hypertension still relies on conventional clinic blood pressure (BP) measurements and thresholds of ≥140/90 mm Hg for systolic (SBP)/diastolic (DBP) BP. However, the correlation between BP level and target organ damage, cardiovascular disease risk, and long-term prognosis is greater for ambulatory BP monitoring (ABPM) than clinic BP measurement. Accordingly, ABPM has been suggested as the logical approach to overcoming the low sensitivity and specificity of clinic BP measurements in pregnancy. With the use of ABPM, differing predictable BP patterns throughout gestation have been identified for clinically healthy and hypertensive pregnant women. In normotensive pregnancies, BP steadily decreases up to the middle of gestation and then increases up to the day of delivery. In contrast, women who develop gestational hypertension or preeclampsia show stable BP during the first half of pregnancy and a continuous linear BP increase thereafter until delivery. Epidemiologic studies have also consistently reported sex differences in the 24-h patterns of ambulatory BP and heart rate. Typically, men exhibit a lower heart rate and higher BP than women, the differences being larger for SBP than DBP. Additionally, as early as in the first trimester of gestation, statistically significant increased 24-h SBP and DBP means characterize women complicated with gestational hypertension or preeclampsia compared with women with uncomplicated pregnancies. However, the normally lower BP in nongravid women as compared with men, additional decrease in BP during the second trimester of gestation in normotensive but not in hypertensive pregnant women, and significant differences in the 24-h BP pattern between healthy and complicated pregnancies at all gestational ages have not been taken into consideration when establishing reference BP thresholds for the

    Full Text Available Pre-eclampsia (PE complicates 2%–8% of all pregnancies and is an important cause of perinatal morbidity and mortality worldwide. In order to reduce these complications and to develop possible treatment modalities, it is important to identify women at risk of developing PE. The use of biomarkers in early pregnancy would allow appropriate stratification into high and low risk pregnancies for the purpose of defining surveillance in pregnancy and to administer interventions. We used formal methods for a systematic review and meta-analyses to assess the accuracy of all biomarkers that have been evaluated so far during the first and early second trimester of pregnancy to predict PE. We found low predictive values using individual biomarkers which included a disintegrin and metalloprotease 12 (ADAM-12, inhibin-A, pregnancy associated plasma protein A (PAPP-A, placental growth factor (PlGF and placental protein 13 (PP-13. The pooled sensitivity of all single biomarkers was 0.40 (95% CI 0.39–0.41 at a false positive rate of 10%. The area under the Summary of Receiver Operating Characteristics Curve (SROC was 0.786 (SE 0.02. When a combination model was used, the predictive value improved to an area under the SROC of 0.893 (SE 0.03. In conclusion, although there are multiple potential biomarkers for PE their efficacy has been inconsistent and comparisons are difficult because of heterogeneity between different studies. Therefore, there is an urgent need for high quality, large-scale multicentre research in biomarkers for PE so that the best predictive marker(s can be identified in order to improve the management of women destined to develop PE.

  2. Early adult psychological consequences for males of adolescent pregnancy and its resolution.

    Using data front 2522 young men who were first surveyed as 7th-grade students in Houston, Texas in 1971, we examined the psychological consequences in early adulthood of having a girlfriend become pregnant in adolescence. By age 21, 15% of the young men were involved in a nonmarital pregnancy. Rates were higher for blacks (24%) than for whites (12%) or Hispanics (16%). Among whites, most adolescent pregnancies were ended by abortion (58%). Adolescent pregnancies to blacks most often resulted in single parenthood (56%). Hispanics tended to have the child, and marry or live together (55%). Consistent with the life course perspective, young men involved in adolescent pregnancies were more psychologically distressed as young adults than those who did not have a girlfriend become pregnant in adolescence. The greater distress in adulthood is not simply a function of accelerated role transitions, because men whose girlfriends had abortions are also distressed, and those who let their girlfriends assume major parenting responsibility are no less distressed than those who became fathers and married or lived with their girlfriends. Subgroup comparisons revealed that psychological distress levels of young black men were not influenced by adolescent pregnancy.

    It is known that infertility affects emotional well-being, satisfaction with life and self-esteem and that failed assisted reproductive technology (ART) treatment is associated with diminished life satisfaction, reduced self-confidence and substantial psychological distress. Investigations of whether these persist when treatment results in a pregnancy and live birth have been undertaken. A systematic search for English-language research articles on psychological and social aspects of pregnancy, childbirth and the first post-partum year after ART conception. Of 466 retrieved papers, 46 met inclusion criteria. These reported data from 28 studies. There is consistent evidence that marital satisfaction, emotional well-being and self-regard in pregnancy, attachment to the fetus and parent-infant relationship in ART groups are similar to comparison groups. Anxiety about the survival of the fetus and early parenting difficulties appear to be higher and post-natal self-confidence lower. Evidence about adjustment to pregnancy and parenthood and the experience of childbirth is inconclusive and reports of parental perceptions of infant temperament and behaviour are contradictory. Between-study methodological differences may explain the lack of consistency in findings of the influence of infertility and ART on some aspects of the transition to parenthood. Overall, this body of evidence is best described as emergent. It is possible that in pregnancy after ART, parenthood might be idealized and this might then hinder adjustment and the development of a confident parental identity.

    The changes in blood serum fructosamine concentrations as indicators of glycaemia during a longer period of time were investigated in mares during late pregnancy and early lactation, as well as their relationship to the changes in the concentration of biochemical indicators of energetic status. The samples were taken from eleven mares on 60 +/- 10 and 20 +/- 10 days before foaling, and 20 +/- 10 and 60 +/- 10 days after foaling. Concentrations of serum fructosamine, non-esterified fatty acids and triglycerides were higher during late pregnancy (from P < 0.05 to P < 0.0005), while the concentrations of beta- hydroxybutyrate increased significantly (P < 0.00001) during early lactation. A significant correlation between the concentrations of fructosamine and metabolic parameters was observed. The results indicate a relationship between energetic status and serum fructosamine in mares. Higher concentrations of fructosamine are related to the adaptation to late pregnancy. Therefore, the measurement of the serum fructosamine concentrations could serve as an indicator of energetic status of mares during pregnancy and lactation.

  5. Possible Roles of CC- and CXC-Chemokines in Regulating Bovine Endometrial Function during Early Pregnancy

    2017-03-01

    Full Text Available The aim of the present study was to determine the possible roles of chemokines in regulating bovine endometrial function during early pregnancy. The expression of six chemokines, including CCL2, CCL8, CCL11, CCL14, CCL16, and CXCL10, was higher in the endometrium at 15 and 18 days of pregnancy than at the same days in non-pregnant animals. Immunohistochemical staining showed that chemokine receptors (CCR1, CCR2, CCR3, and CXCR3 were expressed in the epithelial cells and glandular epithelial cells of the bovine endometrium as well as in the fetal trophoblast obtained from a cow on day 18 of pregnancy. The addition of interferon-τ (IFNT to an endometrial tissue culture system increased CCL8 and CXCL10 expression in the tissues, but did not affect CCL2, CCL11, and CCL16 expression. CCL14 expression by these tissues was inhibited by IFNT. CCL16, but not other chemokines, clearly stimulated interferon-stimulated gene 15 (ISG15 and myxovirus-resistance gene 1 (MX1 expression in these tissues. Cyclooxygenase 2 (COX2 expression decreased after stimulation with CCL8 and CCL14, and oxytocin receptor (OTR expression was decreased by CCL2, CCL8, CCL14, and CXCL10. Collectively, the expression of chemokine genes is increased in the endometrium during early pregnancy. These genes may contribute to the regulation of endometrial function by inhibiting COX2 and OTR expression, subsequently decreasing prostaglandin production and preventing luteolysis in cows.

    For successful embryo implantation, endometrial stromal cells must undergo functional and morphological changes, referred to as decidualization. However, the molecular mechanisms that regulate implantation and decidualization are not well defined. Here we demonstrate that the estradiol- and progesterone-regulated microRNA (miR)-200 family was markedly down-regulated in mouse endometrial stromal cells prior to implantation, whereas zinc finger E-box binding homeobox-1 and -2 and other known and predicted targets were up-regulated. Conversely, miR-200 was up-regulated during in vitro decidualization of human endometrial stromal cells. Knockdown of miR-200 negatively affected decidualization and prevented the mesenchymal-epithelial transition-like changes that accompanied decidual differentiation. Notably, superovulation of mice and humans altered miR-200 expression. Our findings suggest that hormonal alterations that accompany superovulation may negatively impact endometrial development and decidualization by causing aberrant miR-200 expression.

    The purpose of this study was to investigate the relationship between abdominal subcutaneous fat thickness(ASFT) and maternal gestational diabetes mellitus(GDM) measured by ultrasound at period of pregnancy. We compared maternal age, pre-pregnancy body mass index, and weight gain during pregnancy in 286 pregnant women who were diagnosed with early pregnancy ASFT and high GDM screening test(50 g OGTT) of more than 140 mg/dL. ROC curve analysis was used to determine the cut-off value of ASFT for GDM prediction. Maternal age and weight gain during pregnancy were not related to GDM in the mid-trimester and pre-pregnancy body mass index and early pregnancy ASFT were significantly different between normal and GDM high risk groups. The cut-off value of ASFT for GDM prediction was 2.23 cm(AUC 0.913. Sensitivity 76.19%, Specificity 93.72%). ASFT measured by ultrasound in early pregnancy was useful as an important index for predicting mid-trimester GDM prediction. Therefore, ASFT can be used as an auxiliary diagnostic index for early recognition of GDM.

    To evaluate and compare the risk of early pregnancy loss in patients stimulated with GnRH antagonist protocols according to oral contraceptive pill (OCP) pretreatment. Retrospective case-control study. Instituto Valenciano de Infertilidad. University of Valencia. Spain. One thousand five hundred thirty-nine patients, aged <36, stimulated with GnRH antagonists for IVF between January 1, 2000 and November 1, 2005. Reproductive outcome was compared based on the application (or not) of OCP pretreatment: 944 women were included in the OCP group and 595 in the non-OCP group. The Student's t test was used for statistics. Pregnancy, biochemical pregnancy, ectopic pregnancy, early clinical pregnancy loss, early pregnancy loss, and ongoing pregnancy rates. No significant differences were observed in any of the outcome parameters. Early pregnancy loss rates were similar: 23% in the OCP pretreatment group versus 19.2% in the non-OCP pretreatment group. However, longer periods of ovarian stimulation and higher doses of gonadotropins needed to be employed in the OCP group. There is not sufficient evidence to confirm OCP pretreatment as a risk factor for miscarriage in patients stimulated with GnRH antagonist protocols.

    To analyse drug use in early pregnancy with special focus on socio-demographic factors associated with psychotropic and analgesic drug use. Cross-sectional study. A total of 1765 women were invited via their local health care centres, and 1111 participated at 11-16 weeks of pregnancy by filling out a postal questionnaire concerning socio-demographic and obstetric background, stressful life events, and drug use. Drug use prior to and early on in pregnancy, socio-demographic factors, smoking, and adverse life events were investigated. Drug categories screened for were psychotropics (collective term for antidepressants, relaxants, and sleep medication), analgesics, hormones, nicotine, vitamins/minerals, and homeopathic medicine. Drug use from the aforementioned drug categories, excluding vitamins/minerals and homeopathic medicine, was reduced by 18% during early pregnancy, compared with six months prior to conception (49% vs. 60%). Psychotropic drug use during early pregnancy was associated with elementary maternal education (p pregnancy (p pregnancy (p pregnancy. Our results indicate that lack of a support network, stressful life events, and lower status in society may predispose women to more drug use. GPs and midwives responsible for maternity care could take this into account when evaluating risk and gain for women and foetuses in the primary care setting.

    In surrogate pregnancies the genetic parents have little opportunity for early bonding to their infant, either prenatally (in utero) or in the immediate postnatal period. The purpose of this article is to describe a new method for encouraging early parent-infant bonding after surrogate pregnancy by hospitalizing the genetic mother in the maternity ward immediately after the delivery. Two genetic mothers were hospitalized in the maternity ward (rooming-in system) at the Rabin Medical Center in Israel immediately after delivery of their infants by surrogate arrangement. The first birth was a singleton pregnancy with vaginal delivery and the second, a twin pregnancy with delivery by cesarean section. The genetic parents were counseled by a social worker from the adoption agency, starting 3 months before the estimated date of delivery. The parents were referred to the hospital social worker before the delivery. To assess attachment, we observed the parents' behavior toward their children during two daily 15-minute periods of free, unstructured interaction. The parents showed good primary caregiving functions and established affective verbal and physical contact with the infants. They began to recognize the infants' needs and temperament, and exhibited an aura of self-confidence during their interactions. All expressed satisfaction with the method at discharge and reported on reduction of their fears about returning home with the infants. We believe that early hospitalization of the genetic mother in a surrogate delivery may be desirable to establish good and safe early mother-infant bonding, and that it should be considered for adoption as regular hospital policy. Further randomized studies with larger samples over the long term are warranted.

    Being born small for gestational age (SGA) confers increased risks of perinatal morbidity and mortality and increases the risk of cardiovascular complications and diabetes in later life. Accumulating evidence suggests that the etiology of SGA is usually associated with poor placental vascular development in early pregnancy. We examined metabolomic profiles using ultra performance liquid chromatography-mass spectrometry (UPLC-MS) in three independent studies: (a) venous cord plasma from normal and SGA babies, (b) plasma from a rat model of placental insufficiency and controls, and (c) early pregnancy peripheral plasma samples from women who subsequently delivered a SGA baby and controls. Multivariate analysis by cross-validated Partial Least Squares Discriminant Analysis (PLS-DA) of all 3 studies showed a comprehensive and similar disruption of plasma metabolism. A multivariate predictive model combining 19 metabolites produced by a Genetic Algorithm-based search program gave an Odds Ratio for developing SGA of 44, with an area under the Receiver Operator Characteristic curve of 0.9. Sphingolipids, phospholipids, carnitines, and fatty acids were among this panel of metabolites. The finding of a consistent discriminatory metabolite signature in early pregnancy plasma preceding the onset of SGA offers insight into disease pathogenesis and offers the promise of a robust presymptomatic screening test.

    Objective In this double-blind randomized trial, we compare the effect of 75 mg mifeprostone in capsules on termination of early pregnancy was compared with that of 150 mg in tablets combined with misoprostol. Methods A total of 160 patients were randomly divided into two groups with 80 for each group. The capsule group was administered with mifeprostone 75 mg in capsules,placebo tablets and misoprostol 0. 6 mg. The tablet group was administered with mifeprostone 150 mg in tablets, placebo capsules and misoprostol 0. 6 mg.Results The complete abortion rate in the capsule group and in the tablet group was 98. 8% and 97. 5% respectively, with no significant difference (P> 0. 05). There were no significant differences in bleeding time after abortion, side effects, recovery of menstruation or length of menstrual period between the two groups.Conclusion The clinical effect of mifeprostone capsule is the same with that of tablet in combination with misoprostol in terminating early pregnancy, while dose and cost is lower and the side effect is smaller. Mi feprostone capsule is recommended to be widely used for terminating early pregnancy.

    Utero-placental growth and vascular development are critical for pregnancy establishment that may be altered by various factors including assisted reproductive technologies (ART), nutrition, or others, leading to compromised pregnancy. We hypothesized that placental vascularization and expression of angiogenic factors are altered early in pregnancies after transfer of embryos created using selected ART methods. Pregnancies were achieved through natural mating (NAT), or transfer of embryos from natural mating (NAT-ET), or in vitro fertilization (IVF) or activation (IVA). Placental tissues were collected on day 22 of pregnancy. In maternal caruncles (CAR), vascular cell proliferation was less (P<0.05) for IVA than other groups. Compared to NAT, density of blood vessels was less (P<0.05) for IVF and IVA in fetal membranes (FM), and for NAT-ET, IVF and IVA in CAR. In FM, mRNA expression was decreased (P<0.01–0.08) in NAT-ET, IVF and IVA compared to NAT for vascular endothelial growth factor (VEGF) and its receptor FLT-1, placental growth factor (PGF), neuropilin (NP) 1 and 2, angiopoietin (ANGPT) 1 and 2, endothelial nitric oxide synthase (NOS3), hypoxia inducible factor-1A (HIF1A), fibroblast growth factor (FGF) 2 and its receptor FGFR2. In CAR, mRNA expression was decreased (P<0.01–0.05) in NAT-ET, IVF and IVA compared to NAT for VEGF, FLT-1, PGF, ANGPT1 and TEK. Decreased mRNA expression for 12 of 14 angiogenic factors across FM and CAR in NAT-ET, IVF and IVA pregnancies was associated with reduced placental vascular development, which would lead to poor placental function and compromised fetal and placental growth and development.

    Full Text Available Aims. Normal human pregnancy is a complex process of many immunoregulatory mechanisms which protect fetus from the activation of the maternal immune system. The aim of the study was to investigate the apoptosis of lymphocytes in peripheral blood of normal pregnant patients and healthy nonpregnant women. Methods. Sixty pregnant women and 17 nonpregnant women were included in the study. Lymphocytes were isolated and labeled with anti-CD3, anti-CD4, and anti-CD8 monoclonal antibodies. Apoptosis was detected by CMXRos staining and analyzed using the flow cytometric method. Results. We found significantly higher apoptosis of total lymphocytes in peripheral blood of pregnant patients when compared to healthy nonpregnant women. The percentage of apoptotic T CD3+CD8+ cells in the first trimester was significantly higher when compared to the third trimester of normal pregnancy. The ratio of T CD3+CD4+ : T CD3+CD8+ apoptotic lymphocytes was significantly lower in the first trimester when compared to other trimesters of pregnancy and to both of the phases of the menstrual cycle. Conclusions. The higher apoptosis of T CD3+CD8+ lymphocytes and the lower ratio of T CD3+CD4+ : T CD3+CD8+ apoptotic cells in the first trimester of normal pregnancy may suggest a higher susceptibility of T CD3+CD8+ cells for apoptosis as a protective mechanism at the early stage of pregnancy.

    Background Previous studies have shown an association between total excessive gestational weight gain and hypertension in pregnancy. However, this may be a reflection of excessive water retention associated with the pathophysiology of hypertensive disorders of pregnancy. Early excessive weight gain, prior to the third trimester, results in greater maternal fat deposition and inflammation, which has also been associated with the development of hypertension. By focusing on early excessive weight gain, the association between maternal weight gain and the future development of hypertension can be examined. Objective To evaluate the association between early excessive maternal weight gain and the development of hypertension during pregnancy. Study Design This was a secondary analysis of a longitudinal cohort study of 1,441 women without chronic hypertension who were enrolled in a prospective study evaluating maternal angiogenic factors and the prediction of preeclampsia. Initial body mass index (BMI) was calculated by weight and height at the first study visit. Early excessive maternal weight gain was defined as weight gain by 28 weeks that exceeded the Institute of Medicine (IOM) guidelines and was calculated utilizing the maximum amount of weight gain per week recommended by the IOM based on the patient's starting BMI (normal: 0.45 kg; overweight: 0.32 kg; obese: 0.27 kg). Hypertension was defined as a sustained systolic blood pressure of ≥140 mm Hg or a diastolic blood pressure of ≥90 mm Hg. Logistic regression was used to determine the association between early excessive weight gain, initial BMI, and the development of hypertension, including gestational hypertension and preeclampsia, during pregnancy. Results Of 1,441 women, 767 (53.2%) had weight gain that exceeded the IOM guidelines in the first 28 weeks and 154 (10.8%) developed hypertension during pregnancy. Women whose weight gain exceeded the IOM guidelines were more likely to develop

    Full Text Available The objective of the study was to characterize the developmental sequence of pre- and postnatal risk factors for inattention-hyperactivity symptoms in preschoolers.Longitudinal data came from a French population based birth cohort study (EDEN; N = 1311 mother-child pairs followed from the pregnancy onwards. Inattention-hyperactivity symptoms were assessed with the Strengths and Difficulties Questionnaire when participating children were 3 years of age. Potential risk factors were classified in four domains (fetal exposures and child somatic characteristics, child temperament, child neurodevelopmental status, psychosocial environment and four periods (before pregnancy, prenatal/birth, infancy, toddlerhood. Their role as potential moderator or mediator was tested with path analysis to determine the developmental sequence.A low family socioeconomic status before pregnancy was the main environmental risk factor for inattention-hyperactivity symptoms at 3 years, and its effect occurred via two pathways. The first was a risk pathway, where lower SES was associated with higher maternal depression and anxiety during pregnancy; then to higher maternal and child distress and dysregulation in infancy; and in turn to higher levels of inattention-hyperactivity at 3 years. The second was a protective pathway, where higher SES was associated with longer duration of breastfeeding during infancy; then to better child neurodevelopmental status in toddlerhood; and in turn to lower levels of inattention-hyperactivity at 3 years.This study identified psychosocial factors at several developmental periods that represent potential targets for preventing the emergence of inattention-hyperactivity symptoms in early childhood.

    The aim of this study was to investigate the influence of progesterone (P4) on adiponectin system genes and protein expression in the endometrium and myometrium during early gestation. Twenty-five gilts were assigned to 1 of 5 groups ( = 5): d 10 to 11 (embryo migration), 12 to 13 (maternal recognition of pregnancy), 15 to 16 (implantation), and 27 to 28 (end of implantation) of pregnancy and d 10 to 11 of the cycle (fully active corpora lutea, corresponding to the corpora lutea activity during gestation). The endometrial and myometrial tissues were cut into 100 mg slices, treated with P4 (10, 100, 1000 nM) and incubated for 24 h. Gene expression was analyzed by the real-time PCR method. Adiponectin secretion was determined by ELISA. Receptor protein content was defined using Western Blot analysis. In the endometrium, on d 10 to 11 of pregnancy, P4 stimulated adiponectin protein secretion. On those days, P4 enhanced adiponectin receptor type 1 () and type 2 () gene expression but inhibited both receptors' protein content. On d 12 to 13 of pregnancy, P4 inhibited adiponectin gene expression. During those period, P4 enhanced gene expression but suppressed both receptors' protein content. On d 15 to 16 of gestation, P4 increased adiponectin gene expression but inhibited the protein secretion. During those days, P4 suppressed gene expression and enhanced AdipoR2 protein content. On d 27 to 28 of gestation, P4 enhanced gene and AdipoR1 protein expression ( adiponectin and genes and AdipoR1 protein expression but decreased AdipoR2 protein content. On d 15 to 16 of gestation, P4 inhibited adiponectin gene expression. On those days, P4 enhanced gene and protein expression. On d 27 to 28 of gestation, P4 decreased adiponectin gene expression. On those days, P4 increased the myometrial AdipoR2 protein concentration and decreased gene protein expression ( adiponectin system in the porcine uterus during early pregnancy, which may suggest the involvement of this adipokine in

    Full Text Available Hyaluronan (HA and its receptor CD44 are expressed at the maternal-fetal interface, but its role in early pregnancy remains unclear. Here, we found that primary decidual stromal cells (DSCs continuously secreted HA and expressed its receptor CD44. Pregnancy-associated hormones up-regulated HA synthetase (HAS 2 transcription and HA release from DSCs. High molecular weight-HA (HMW-HA, but not medium molecular weight (MMW-HA or low molecular weight (LMW-HA, promoted proliferation and inhibited apoptosis of DSCs in a CD44-dependent manner. The in-cell Western analysis revealed HMW-HA activated PI3K/AKT and mitogen-activated protein kinase (MAPK/ERK1/2 signaling pathways time-dependently. Blocking these pathways by specific inhibitor LY294002 or U0126 abrogated HMW-HA-regulated DSc proliferation and apoptosis. Finally, we have found that HA content, HA molecular weight, HAS2 mRNA level, and CD44 expression were significantly decreased in DSCs from unexplained miscarriage compared with the normal pregnancy. Collectively, our results indicate that higher level and greater molecular mass of HA at maternal-fetal interface contributes to DSc growth and maintenance of DSCs in human early pregnancy.

    Evidence from basic science studies supports a causative relationship between antiphospholipid antibodies (aPL) and recurrent early miscarriage (REM) (prior to 10 weeks of gestation). However, human studies have not consistently found a relationship between aPL and REM. Members of the Obstetric Task Force of the 14th International Congress on Antiphospholipid Antibodies performed a literature review of the association of aPL and REM and searched for clinical trials in women with REM who tested positive for aPL. Of the 46 studies that investigated the relationship between aPL and REM, 27 found a positive association, seven found no association, and the remaining 12 papers could not report an association (lack of control group). The main identified problems for such conflicting results were varying definitions of REM (two or three abortions, not necessarily consecutive; different gestational age at which pregnancy losses occurred); analysis of patients with previous fetal death (>10 weeks) in the same group of REM; and different definitions of "positive aPL" (cutoffs not following international recommendations; small number of studies confirmed persistence of positive aPL after six to 12 weeks). The 10 identified randomized trials with proposed treatments for women with REM who test positive for aPL also had heterogeneous inclusion criteria, with only one trial limited to subjects who would meet the current criteria for antiphospholipid syndrome (APS) by both clinical and laboratory criteria. Against this background, we conclude that the association between REM and aPL remains inconclusive and that the findings of treatment trials are at best inconsistent and at worst misleading. More convincing data are critically needed. Studies that identify, or at least stratify, according to international consensus criteria and include standardized core laboratory testing results are crucial if we are to establish an evidence-based association between aPL and REM and treatment

    Orexin A and B are hypothalamic peptides derived from the prepro-orexin (PPO) precursor. Orexins stimulate food intake and arousal. Those peptides bind and activate two G protein-coupled receptors: orexin receptor 1 (OX1R) and orexin receptor 2 (OX2R). Numerous authors have suggested that orexins play an important role in the regulation of the reproductive functions. The objective of the present study was to analyse the presence of and changes in the gene and protein expression pattern of the orexin system in the porcine uterus, conceptus and trophoblast (chorioallantois) during early pregnancy. In the endometrium, the highest PPO and OX1R gene expression was detected on days 15 to 16 of gestation. The OX2R mRNA content in the endometrium was higher on days 10 to 11 and 15 to 16 than on days 12 to 13 and 27 to 28. In the trophoblasts, PPO gene expression was higher on days 30 to 32 than on days 27 to 28. The highest PPO protein content in the endometrium was noted on days 12 to 13. The highest OX1R protein content in the endometrium was detected on days 10 to 11, whereas OX2R protein on days 15 to 16. In the trophoblasts, PPO and OX1R protein levels were more pronounced on days 27 to 28 than on days 30 to 32, but OX2R expression was higher on days 30 to 32. The expression of PPO, OX1R and OX2R was different in the conceptuses and trophoblasts during early pregnancy. Local orexin production and the presence of the specific orexin receptors suggest that the orexin system may participate in the control of porcine reproductive functions by exerting endocrine and auto/paracrine effects on the uterus, conceptuses and trophoblasts during early pregnancy. This study provides the first evidence for the presence of orexins and their receptors in the uteri, conceptuses and trophoblasts in pigs during early pregnancy. The local orexin system is dependent on the stage of pregnancy.

    During pregnancy, important changes take place in maternal metabolism because of the growing fetus and placental formation. The increase in insulin resistance during pregnancy is paralleled by the progressive increase of maternal adipose tissue deposition. This review examines the topography of fat mass deposition during pregnancy in relation to factors such as parity and maternal age that might affect this deposition. We also examine adipose tissue markers, such as pregravid weight and weight gain during pregnancy, and their effect on fetal growth and pregnancy outcomes. In addition, this review studies the possible effects of cytokines that are produced by adipose tissue and the placenta on maternal metabolism and its complications. Finally, we also consider the possible role of maternal adipocytokines and fetal adipocytokines on fetal growth. © 2010 New York Academy of Sciences.

    Background & objectives: Asymptomatic bacteriuria during pregnancy if left untreated, may lead to acute pyelonephritis, preterm labour, low birth weight foetus, etc. Adequate and early treatment reduces the incidence of these obstetric complications. The present study was done to determine presence of asymptomatic bacteriuria (ASB) and obstetric outcome following treatment in early versus late pregnancy. Methods: A prospective cohort study was conducted at a tertiary care teaching hospital of north India. Pregnant women till 20 wk (n=371) and between 32 to 34 wk gestation (n=274) having no urinary complaints were included. Their mid stream urine sample was sent for culture and sensitivity. Women having > 105 colony forming units/ml of single organism were diagnosed positive for ASB and treated. They were followed till delivery for obstetric outcome. Relative risk with 95% confidence interval was used to describe association between ASB and outcome of interest. Results: ASB was found in 17 per cent pregnant women till 20 wk and in 16 per cent between 32 to 34 wk gestation. Increased incidence of preeclamptic toxaemia (PET) [RR 3.79, 95% CI 1.80-7.97], preterm premature rupture of membrane (PPROM)[RR 3.63, 45% CI 1.63-8.07], preterm labour (PTL) [RR 3.27, 95% CI 1.38-7.72], intrauterine growth restriction (IUGR)[RR 3.79, 95% CI 1.80-79], low birth weight (LBW) [RR1.37, 95% CI 0.71-2.61] was seen in late detected women (32-34 wk) as compared to ASB negative women, whereas no significant difference was seen in early detected women (till 20 wk) as compared to ASB negative women. Interpretation & conclusions: Early detection and treatment of ASB during pregnancy prevents complications like PET, IUGR, PTL, PPROM and LBW. Therefore, screening and treatment of ASB may be incorporated as routine antenatal care for safe motherhood and healthy newborn. PMID:23703344

    Full Text Available Introduction: Adolescents having unprotected heterosexual intercourse are at risk of HIV infection and unwanted pregnancy. However, there is little evidence to indicate whether pregnancy in early adolescence increases the risk of subsequent HIV infection. In this paper, we tested the hypothesis that adolescent pregnancy (aged 15 or younger increases the risk of incident HIV infection in young South African women. Methods: We assessed 1099 HIV-negative women, aged 15–26 years, who were volunteer participants in a cluster-randomized, controlled HIV prevention trial in the predominantly rural Eastern Cape province of South Africa. All of these young women had at least one additional HIV test over two years of follow-up. Outcomes were HIV incidence rates per 100 person years and HIV incidence rate ratios (IRRs estimated by Poisson multivariate models. Three pregnancy categories were created for the Poisson model: early adolescent pregnancy (a first pregnancy at age 15 years or younger; later adolescent pregnancy (a first pregnancy at age 16 to 19 years; and women who did not report an adolescent pregnancy. Models were adjusted for study design, age, education, time since first sexual experience, socio-economic status, childhood trauma and herpes simplex virus type 2 infection. Results: HIV incidence rates were 6.0 per 100 person years over two years of follow-up. The adjusted IRR was 3.02 (95% CI 1.50–6.09 for a pregnancy occurring at age 15 or younger. Women with pregnancies occurring between 16 and 19 years of age did not have a higher incidence of HIV (IRR 1.08; 95% CI 0.64–1.84. Early adolescent pregnancies were associated with higher partner numbers and a greater age difference with partners. Conclusions: Early adolescent pregnancies increase the incidence of HIV among South African women. The higher risk is associated with sexual risk behaviours such as higher partner numbers and a greater age difference with partners rather than a

    Requests for termination of pregnancy (TOP) at very early gestation (≤6 weeks) can prove challenging for abortion services as the ultrasound feature usually accepted as definitive evidence of an intrauterine pregnancy (IUP), the presence of a yolk sac within a gestational sac, may not yet be evident. In 2011 the Edinburgh TOP service introduced a protocol permitting women to proceed to treatment without further investigations provided that ultrasound showed the features of an eccentrically placed gestational sac (≥3 mm) with a decidual reaction, and there were no signs, symptoms or risk factors for ectopic pregnancy. A retrospective audit was conducted of outcomes of women presenting for TOP at ≤6 weeks' gestation over a 2-year period using the hospital computerised database. A total of 1155 women presented for TOP with an ultrasound gestational age of ≤6 weeks. Of these, 1030 (89%) had ultrasound evidence of a yolk sac. Eighty-seven women (7.5%) had an eccentrically placed gestational sac with a decidual reaction. All 87 women fulfilled our criteria to proceed to medical TOP, and 66 did so. In the remaining 21 cases, further investigations were performed before they proceeded to medical TOP. Two (0.17%) medical TOPs failed, both in women whose initial ultrasound had shown a yolk sac. Women with ultrasound features consistent with a very early IUP (≥3 mm eccentrically placed gestational sac with a decidual reaction) and without signs, symptoms or risk factors for ectopic pregnancy can proceed directly to medical TOP without the need for delay for further ultrasonography.

    The goal of this study was to describe the alterations in the transcriptome of the endometrium in pigs during the beginning of implantation (days 15-16 of pregnancy) compared to cyclic pigs during the onset of luteolysis (days 15-16 of the estrous cycle). The global expression of genes in porcine gravid and non-gravid endometria was investigated using the Porcine (V2) Two-color gene expression microarray, 4 × 44 (Agilent, USA). Analysis of the microarray data showed that, of 589 accurately annotated genes, the expression of 266 genes was up-regulated and expression of 323 was down-regulated in the endometrium harvested during early pregnancy compared with the endometrium during the estrous cycle. In pregnant pigs, genes with the most significantly altered expression were involved in the following biological processes: the metabolic process, cellular process, cell communication, immune system process, developmental process, cell adhesion, antigen processing and presentation, antigen processing and presentation of peptide or polysaccharide antigen via major histocompatibility complex (MHC) class II, immune response, and the polysaccharide metabolic process. In the pregnant endometrium, cell adhesion molecules and steroid hormone biosynthesis pathways were the most significantly enriched biological pathways. Analysis of the interaction network among selected genes showed that androgen receptor (AR) encoding genes interact with genes involved in important processes occurring during early pregnancy. The bioinformatic analysis revealed information about the meaning of differentially expressed genes. The data provided new insight into the dynamic changes of the endometrial gene expression profile during days 15-16 of pregnancy.

    To examine the effects of binge alcohol consumption during early pregnancy, including the number of binge episodes and the timing of binge drinking, on general intelligence in 5-year-old children. Follow-up study. Neuropsychological testing in four Danish cities 2003-2008. A cohort of 1617 women and their children sampled from the Danish National Birth Cohort. Participants were sampled on the basis of maternal alcohol consumption during pregnancy. At 5 years of age the children were tested with six subtests from the Wechsler Preschool and Primary Scale of Intelligence - Revised (WPPSI-R). Parental education, maternal IQ, prenatal maternal smoking, the child's age at testing, the gender of the child, and tester were considered core confounding factors, whereas the full model also controlled for prenatal maternal average alcohol intake, maternal age, maternal pre-pregnancy body mass index (BMI), parity, home environment, postnatal parental smoking, health status, and indicators for hearing and vision impairment. WPPSI-R. There were no systematic or significant differences in general intelligence between children of mothers reporting binge drinking and children of mothers with no binge episodes, except that binge drinking in gestational weeks 1-2 significantly reduced the risk of low, full-scale IQ (OR 0.54; 95% CI 0.31-0.96) when adjusted for core confounding factors. The results were otherwise not statistically significantly related to the number of binge episodes (with a maximum of 12) and timing of binge drinking. We found no systematic association between binge drinking during early pregnancy and child intelligence. However, binge drinking reduced the risk of low, full-scale IQ in gestational weeks 1-2. This finding may be explained by residual confounding. © 2012 The Authors BJOG An International Journal of Obstetrics and Gynaecology © 2012 RCOG.

    To determine 20- and 40-week fetal outcomes following documentation of fetal cardiac activity (FCA) and intrauterine pregnancy (IUP) in women at less than 20 weeks' gestation presenting to the emergency department (ED) with vaginal bleeding. Prospective observational cohort study. Single-centre tertiary care ED. Pregnant women at less than 20 weeks' gestation presenting to the ED with vaginal bleeding. All study participants underwent ED point-of-care ultrasound (POCUS) to document IUP and FCA. Prevalence of spontaneous abortion or pregnancy loss by 40 weeks' gestational age following ED POCUS documentation of FCA or IUP in women at less than 20 weeks' gestation. A total of 85 of 111 eligible patients were enrolled; FCA and IUP were detected in 43 (50.6%) and 54 (63.5%) participants, respectively. Participants with documented FCA on ED POCUS were less likely to experience pregnancy loss than participants without documented FCA were (5.0% vs 92.7%; Δ = 87.7%; 95% CI 71.0% to 93.7%), and participants with documented IUP were less likely to experience pregnancy loss than participants without documented IUP were (22.0% vs 93.5%; Δ = 71.5%; 95% CI 52.1% to 81.9%). Compared with radiologist-interpreted ultrasound, ED POCUS had sensitivity of 88.9% (95% CI 75.9% to 96.2%) and specificity of 100.0% (95% CI 89.6% to 100.0%) for documenting FCA, and sensitivity of 96.0% (95% CI 86.3% to 99.4%) and specificity of 93.1% (95% CI 77.2% to 99.0%) for documenting IUP. In this cohort of women presenting to the ED with bleeding in the first 20 weeks of pregnancy, detection of IUP and especially FCA using POCUS performed by providers certified by the Canadian Emergency Ultrasound Society was associated with ongoing viable pregnancy at 20 and 40 weeks' gestational age. These data might be useful for ED physicians counseling women with symptomatic early pregnancies about the chance of miscarriage after an episode of vaginal bleeding.

    Do number of cells in the transferred cleavage stage embryo and number of oocytes retrieved for IVF influence maternal hCG concentrations in early pregnancies? Compared with transfer of a 2-cell embryo, transfer of a 4-cell embryo results in higher hCG concentrations on Day 12 after transfer, and more than 20 oocytes retrieved were associated with low hCG concentrations. Maternal hCG concentration in very early pregnancy varies considerably among women, but is likely to be an indicator of time since implantation of the embryo into the endometrium, in addition to number and function of trophoblast cells. We followed 1047 pregnancies after IVF/ICSI from oocyte retrieval until Day 12 after embryo transfer. Women were recruited in Norway during the years 2005-2013. Successful pregnancies after transfer of one single embryo that had been cultured for 2 days were included. Maternal hCG was quantified on Day 12 after embryo transfer by chemiluminescence immunoassay, which measures intact hCG and the free β-hCG chain. Information on a successful pregnancy, defined as birth after >16 weeks, was obtained by linkage to the Medical Birth Registry of Norway. Transfer of a 4-cell embryo resulted in higher maternal hCG concentrations compared with transfer of a 2-cell embryo (134.8 versus 87.8 IU/l, P 20) was associated with low hCG concentrations (P hCG concentrations in early pregnancy. Although embryo transfer was performed at the same time after fertilization, we do not know the exact time of implantation. A further limitation to our study is that the number of pregnancies after transfer of a 2-cell embryo was small (27 cases). Number of cells in the transferred embryo and number of oocytes retrieved may influence the conditions and timing for embryo implantation in different ways and thereby influence maternal hCG concentrations. Such knowledge may be important for interpretation of hCG concentrations in early pregnancy. © The Author 2015. Published by Oxford University

    Full Text Available The endocrinology of human pregnancy involves endocrine and metabolic changes that result from physiological alterations at the boundary between mother and fetus. Progesterone and oestrogen have a great role along with other hormones. The controversies of use of progestogen and others are discussed in this chapter. Progesterone has been shown to stimulate the secretion of Th2 and reduces the secretion of Th1 cytokines which maintains pregnancy. Supportive care in early pregnancy is associated with a significant beneficial effect on pregnancy outcome. Prophylactic hormonal supplementation can be recommended for all assisted reproduction techniques cycles. Preterm labor can be prevented by the use of progestogen. The route of administration plays an important role in the drug′s safety and efficacy profile in different trimesters of pregnancy. Thyroid disorders have a great impact on pregnancy outcome and needs to be monitored and treated accordingly. Method of locating review: Pubmed, scopus

    Full Text Available Background : Recurrent spontaneous pregnancy (RSA is defined as a sequence of three or more consecutive spontaneous abortions. One of the major causes of RSA is immunological where alloimmune antibodies develop towards human leucocyte antigen (HLA antigens. Earlier research had suggested that anti-HLA antibodies are produced in normal women; studies have been reported that normal pregnant women develop anti-HLA antibodies, mostly after 20-28 weeks of gestation. Aim : To evaluate the role of anti-HLA antibodies in RSA patients Materials and Methods : A total of 80 randomly selected couples with unexplained three or more RSA and control group of 50 normal pregnant women were screened for anti-HLA A and B antibodies. The anti-HLA antibodies were analyzed following the standard two-stage NIH microlymphocytotoxicity assay. Results : In our study group a high frequency of anti-HLA antibodies among women with RSA (26.25% was detected compared to normal pregnant women (8.0%. Most of the sera showed HLA-A and HLA-B antibodies which had high titer, up to a dilution of 1: 4096. Conclusion : This incidence of high anti-HLA antibodies in RSA women during early weeks of gestation may explain the recurrent pregnancy loss.

    Most studies of alcohol consumption in pregnancy have looked at one time point only, often relying on recall. The aim of this longitudinal study was to determine whether alcohol consumption changes in early and late pregnancy and whether this affects perinatal outcomes. We performed a prospective cohort study, conducted from November 2010 to December 2011 at a teaching hospital in the Republic of Ireland. Of the 907 women with a singleton pregnancy who booked for antenatal care and delivered at the hospital, 185 (20%) abstained from alcohol in the first trimester but drank in the third trimester, 105 (12%) consumed alcohol in the first and third trimesters, and the remaining 617 (68%) consumed no alcohol in pregnancy. Factors associated with continuing to drink in pregnancy included older maternal age (30-39 years), Irish nationality, private healthcare, smoking, and a history of illicit drug use. Compared to pre-pregnancy, alcohol consumption in pregnancy was markedly reduced, with the majority of drinkers consuming ≤ 5 units per week (92% in first trimester, 72-75% in third trimester). Perhaps because of this, perinatal outcomes were similar for non-drinkers, women who abstained from alcohol in the first trimester, and women who drank in the first and third trimester of pregnancy. Most women moderate their alcohol consumption in pregnancy, especially in the first trimester, and have perinatal outcomes similar to those who abstain.

    The health risks associated with e-cigarette use in pregnancy are mostly unknown. Guidelines by the World Health Organization and national health agencies warn women against using e-cigarettes in pregnancy; however, in the UK, a recent multiagency guideline takes a different approach by not discouraging e-cigarette use in pregnancy. Furthermore, e-Voke(™) , an e-cigarette, has been approved for use in pregnancy in the UK. We analyze United Nations human rights treaties to examine how they might inform best practice recommendations for e-cigarette use in pregnancy. These treaties oblige Parties to adopt policies that protect children's and women's right to health, appropriate pregnancy services, and health education. We argue that clinical practice guidelines related to use of e-cigarettes in pregnancy should consider both evidence and human rights principles, and ensure that healthcare providers and patients are given clear, accurate messages about the known and potential risks associated with e-cigarette use in pregnancy. © 2017 Nordic Federation of Societies of Obstetrics and Gynecology, Acta Obstetricia et Gynecologica Scandinavica.

    Previous studies have reported inconsistent associations between maternal serum ferritin concentrations and the risk of spontaneous preterm birth (sPTB). The aim of the present study was to examine the association between Fe biomarkers, including serum ferritin concentrations, and the risk of total ( 75th percentile ( ≥ 43 μg/l) (OR 1.49, 95% CI 1.06, 2.10) and >90th percentile ( ≥ 68 μg/l) (OR 1.92, 95% CI 1.25, 2.96). Increased odds of early and moderate-to-late sPTB were associated with ferritin levels >90th percentile (OR 2.50, 95% CI 1.32, 4.73) and >75th percentile (OR 1.56, 95% CI 1.03, 2.37), respectively. No association was found between the risk of sPTB and elevated sTfR levels or Fe deficiency. In conclusion, elevated maternal serum ferritin levels in early pregnancy are associated with an increased risk of sPTB from 34 weeks of gestation. The usefulness of early pregnancy ferritin levels in identifying women at risk of sPTB warrants further investigation.

    Two experiments were conducted to examine the temporal aspects of luteal resistance to the luteolytic effect of prostaglandin (PG) F2 alpha during early pregnancy. In Exp. 1, 14 pregnant and 12 nonpregnant ewes were treated with PGF2 alpha either on d 10 or 13 post-estrus. Jugular venous blood samples were collected at -30 min, 0, 6, 12, 18, 24, 30 and 36 h post-injection for quantification of progesterone. The difference (delta P) between pre-treatment and post-treatment concentrations of progesterone was calculated for each ewe. There was a significant interaction between pregnancy status and day of treatment on delta P (P less than .05). Pregnant and nonpregnant ewes treated on d 10 showed a large delta P. A large delta P also was observed in nonpregnant ewes treated on d 13 post-estrus. However, delta P in pregnant ewes treated on d 13 was smaller than in the other three groups (P less than .05). The temporal patterns of concentrations of progesterone in serum were different among treatment groups (P less than .05). A suppression in the concentration of progesterone was observed by 24 h post-injection in all four treatment groups. Progesterone returned to pre-treatment levels only in pregnant ewes treated on d 13. In Exp. 2, 47 pregnant ewes were treated with PGF2 alpha on d 10, 13, 16, 19, 22, 26 or 30 postestrus. Blood samples were collected and data were analyzed as described for Exp. 1.(ABSTRACT TRUNCATED AT 250 WORDS)

    The present prospective study examines proportions of maternal erythrocyte fatty acids across gestation and their association with cord erythrocyte fatty acids in normotensive control (NC) and preeclamptic pregnancies. We hypothesize that maternal fatty acid status in early pregnancy influences fetal fatty acid stores in preeclampsia. 137 NC women and 58 women with preeclampsia were included in this study. Maternal blood was collected at 3 time points during pregnancy (16-20th weeks, 26-30th weeks and at delivery). Cord blood was collected at delivery. Fatty acids were analyzed using gas chromatography. The proportions of maternal erythrocyte α-linolenic acid, docosahexaenoic acid, nervonic acid, and monounsaturated fatty acids (MUFA) (p preeclampsia as compared with NC. Cord 18:3n-3, 22:6n-3, 24:1n-9, MUFA, and total n-3 fatty acids (p preeclampsia as compared with NC. A positive association was observed between maternal erythrocyte 22:6n-3 and 24:1n-9 at 16-20th weeks with the same fatty acids in cord erythrocytes (p preeclampsia. Our study for the first time indicates alteration in maternal erythrocyte fatty acids at 16th weeks of gestation which is further reflected in cord erythrocytes at delivery in preeclampsia.

    Recent data have indicated a relationship between placental oxygen and angiogenic protein levels in the first trimester of normal pregnancies. Our objective was to investigate if maternal serum levels of angiogenic factors Soluble vascular endothelial growth factor (VEGF) receptor 1 (sFlt-1), soluble Endoglin and placental growth factor (PlGF) are altered in women with symptoms of threatened miscarriage (TM) and if they are predictive of a subsequent miscarriage. Blood samples were collected at 6-10 weeks from women presenting with TM (n = 40), from asymptomatic controls (n = 32) and from non- pregnant women in their luteal phase (n = 14). All samples were assayed for serum level of sFLT-1, PlGF, sEndoglin and HSP70 using commercial ELISAs. Samples were analysed retrospectively on the basis of pregnancy outcome. TM group included 21 women with a normal pregnancy outcome and 19 with subsequent complete miscarriage. The latter subgroup had significantly lower mean maternal serum (MS) sFlt-1 (83%, P<0.001) and PlGF (44%, P<0.001) compared to those with a normal pregnancy outcome. Asymptomatic control pregnant women had similar MS levels of sFlt-1 and PlGF compared to the TM patients with a normal outcome. The mean MS sFlt-1 (>10 fold) and MS PlGF ( approximately 2 fold) levels were significantly (P<0.001) higher in control pregnant women compared to the non-pregnant group in the luteal phase of the menstrual cycle. Soluble Endoglin was not altered in the normal pregnant women compared to non pregnant women, although lower in the TM subgroup with a subsequent miscarriage ( approximately 25%, P<0.001) compared to TM with a live birth. There was no significant difference in the mean MS HSP 70 levels between the different groups. This study shows that sFlt1 and PlGF MS levels are increased by several folds in early pregnancy and that MS sFlt-1 and MS PlGF are markedly decreased in threatened miscarriage patients who subsequently have a miscarriage suggesting these

The initial cohort (Cohort I) that underwent IVF between January 2011 and March 2012 included a total of 68 attempted IVF cycles. Thirty-four cycles were treated with the conventional GnRH antagonist protocol, and 34 cycles with an early GnRH antagonist start protocol. The second cohort (Cohort II) that underwent IVF between June 2012 and February 2013 included a total of 150 embryo-transfer (ET) cycles. Forty-three cycles were treated with the conventional GnRH antagonist protocol, 34 cycles with the modified early GnRH antagonist start protocol using highly purified human menopause gonadotropin and an addition of GnRH agonist to the luteal phase support, and 73 cycles with the GnRH agonist long protocol. The analysis of Cohort I showed that the number of mature oocytes retrieved was significantly higher in the early GnRH antagonist start cycles than in the conventional antagonist cycles (11.9 vs. 8.2, p=0.04). The analysis of Cohort II revealed higher but non-significant CPR/ET in the modified early GnRH antagonist start cycles (41.2%) than in the conventional antagonist cycles (30.2%), which was comparable to that of the GnRH agonist long protocol cycles (39.7%). The modified early antagonist start protocol may improve the mature oocyte yield, possibly via enhanced follicular synchronization, while resulting in superior CPR as compared to the conventional antagonist protocol, which needs to be studied further in prospective randomized controlled trials.

    Background: Air pollution has been linked to gestational diabetes mellitus (GDM) but no studies have evaluated impact of preconception and early pregnancy air pollution exposures on GDM risk. Methods: Electronic medical records provided data on 219,952 singleton deliveries to mothers with (n=11,334) and without GDM (n=208,618). Average maternal exposures to particulate matter (PM) ≤ 2.5 μm (PM{sub 2.5}) and PM{sub 2.5} constituents, PM ≤ 10 μm (PM{sub 10}), nitrogen oxides (NO{sub x}), carbon monoxide, sulfur dioxide (SO{sub 2}) and ozone (O{sub 3}) were estimated for the 3-month preconception window, first trimester, and gestational weeks 1–24 based on modified Community Multiscale Air Quality models for delivery hospital referral regions. Binary regression models with robust standard errors estimated relative risks (RR) for GDM per interquartile range (IQR) increase in pollutant concentrations adjusted for study site, maternal age and race/ethnicity. Results: Preconception maternal exposure to NO{sub X} (RR=1.09, 95% CI: 1.04, 1.13) and SO{sub 2} (RR=1.05, 1.01, 1.09) were associated with increased risk of subsequent GDM and risk estimates remained elevated for first trimester exposure. Preconception O{sub 3} was associated with lower risk of subsequent GDM (RR=0.93, 0.90, 0.96) but risks increased later in pregnancy. Conclusion: Maternal exposures to NO{sub x} and SO{sub 2} preconception and during the first few weeks of pregnancy were associated with increased GDM risk. O{sub 3} appeared to increase GDM risk in association with mid-pregnancy exposure but not in earlier time windows. These common exposures merit further investigation. - Highlights: • Air pollution may be related to gestational diabetes (GDM). • No prior studies have examined preconception exposure. • Maternal exposure to NO{sub x} and SO{sub 2} before conception increased subsequent GDM risk. • NO{sub x} and SO{sub 2} exposure in the first seven weeks of pregnancy also increased

  16. Medication use in early pregnancy-prevalence and determinants of use in a prospective cohort of women.

    PURPOSE: To examine the extent, nature and determinants of medication use in early pregnancy. METHODS: We reviewed early pregnancy medication use, as reported to a midwife at the booking interview, in women delivering between 2000 and 2007 in a large maternity hospital in Dublin, Ireland (n = 61 252). RESULTS: Excluding folic acid, at least one medication was reported in 23 989 (39.2%) pregnancies. Over the counter (OTC) medications were reported in 11 970 (19.5%) pregnancies, illicit drugs or methadone in 545 (0.9%) and herbal medicines\\/supplements in 352 (0.58%). FDA category D and X medications were reported by 1532 (2.5%) and 1987 (3.2%) women. Asthma, depression and hypertension were among the most commonly reported chronic medical disorders. Medications with potential for foetal harm were reported by 86 (15.7%) women treated for depression and 68 (20%) women treated for hypertension. Factors associated with reporting the use of medications with potential for foetal harm included unplanned pregnancy (adjusted odds ratio [aOR] 1.31, 95% confidence interval [CI] 1.12-1.52), booking at less than 12 weeks gestation (aOR 1.83, 95%CI 1.58-2.13), being above 25 years of age, unemployed (aOR 2.58, 95%CI 2.03-3.29), nulliparous (aOR 1.41; 95%CI 1.22-1.63), single (aOR 1.28; 95%CI 1.06-1.54) or smoking during pregnancy (aOR 1.96, 95%CI 1.67-2.28). CONCLUSIONS: Women frequently report medication use in early pregnancy. Women and prescribers need to be aware of the lack of pregnancy safety data for many medications, and the need for pre-pregnancy planning. Prescribers should ensure that optimal medications are used when treating women of childbearing potential with chronic medical disorders.

    To assess the predictive value of the combination of ultrasound scanning, yolk sacs and CA125 levels for pregnancy outcomes in early threatened abortion. A total 196 pregnant women at less than 12 weeks gestation were enrolled. They were assigned into: (A) normal pregnancy (n = 61); (B) early threatened abortion but with favorable outcomes after active treatment (n = 56); (C) pregnancy with spontaneous miscarriage and threatened abortions (n = 79). The yolk sacs were examined and serum CA125 levels were measured. The visualization rate in groups A and B were significantly higher than that in group C. For the mean yolk sac diameter, there was a statistically significant difference between groups A and C (p 0.05). The mean serum CA125 levels were significantly different (p ultrasound scanning of yolk sacs and measurement of serum CA125 levels is of great value for predicting pregnancy outcomes.

    This experiment investigated whether allopregnanolone, a neurosteroid metabolite from progesterone, modulates the stress response during early pregnancy. Twenty-five nulliparous sows (Sus scrofa) were allocated to one of three treatments: pregnant, ovariectomized or ovariectomized administered daily intravenously with alfaxalone as a synthetic allopregnanolone analog. On days 5, 12 and 19 of pregnancy, all sows were subjected to social stress by submitting them individually to a resident-intruder test, acting as the intruder. Blood samples were collected to analyze plasma progesterone, allopregnanolone, cortisol and adrenocorticotropic hormone (ACTH) concentrations. On day 26, 10 sows across the three treatments were subjected to a dexamethasone suppression test followed by a corticotrophin-releasing hormone administration to test the functionality of their hypothalamo-pituitary-adrenal (HPA) axis through cortisol release. Pregnant sows returned more rapidly to baseline cortisol concentrations following the resident-intruder test (p = 0.006). However, there were no other differences in cortisol or ACTH concentrations according to treatment or day, or to the HPA responsivity test on day 26. Allopregnanolone concentration in pregnant sows was higher than in ovariectomized sows (p pregnancy. Allopregnanolone concentration was correlated with longer resident-intruder test duration (pregnant: r = 0.66, p = 0.0003; ovariectomized: r = 0.47, p = 0.03), reflecting lower aggressiveness, and with progesterone concentration (r = 0.25, p = 0.03). Alfaxalone administration raised plasma allopregnanolone concentration in alfaxalone-administered sows but resulted in little behavioral and physiological effects. These findings did not support the hypothesis that the stress response of the female pig changes in the first third of pregnancy. Allopregnanolone was associated with lower aggression in social encounters.

    This study examines the differential role of calcium signaling pathway(s) in histamine-induced uterotonic action during early and mid-pregnancy stages in buffaloes. Compared to mid pregnancy, tonic contraction, amplitude and mean-integral tension were significantly increased by histamine to produce myometrial contraction during early pregnancy with small effects on phasic contraction and frequency. Although uterotonic action of histamine during both stages of pregnancy is sensitive to nifedipine (a L-type Ca(2+) channels blocker) and NNC55-0396 (T-type Ca(2+) channels blocker), the role of extracellular calcium seems to be more significant during mid-pregnancy as in this stage histamine produced only 9.38±0.96% contraction in Ca(2+) free-RLS compared to 21.60±1.45% in uteri of early pregnancy stage. Intracellular calcium plays major role in histamine-induced myometrial contraction during early pregnancy as compared to mid pregnancy, as in the presence of cyclopiazonic acid (CPA) Ca(2+)-free RLS, histamine produced significantly higher contraction in myometrial strips of early-pregancy in comparison to mid-pregnancy (10.59±1.58% and 3.13±0.46%, respectively). In the presence of U-73122, the DRC of histamine was significantly shifted towards right with decrease in maximal effect (Emax) only in early pregnancy suggesting the predominant role of phospholipase-C (PL-C) in this stage of pregnancy.

    This article draws on data from the ongoing federal Evaluation of Adolescent Pregnancy Prevention Approaches to discuss the early implementation experiences of two new and innovative programs intended to delay rapid repeat pregnancy among teen mothers: (1) AIM 4 Teen Moms, in Los Angeles County, California; and (2) Teen Options to Prevent Pregnancy (T.O.P.P.), in Columbus, Ohio. Program staff report common challenges in working with teen mothers, particularly concerning recruitment and retention, staff capacity and training, barriers to participation, and participants' overarching service needs. Lessons learned in addressing these challenges provide useful guidance to program developers, providers, policy makers, and stakeholders working with similar populations.

    Maternal nutrition and inflammation have been suggested as mediators in the development of various adverse pregnancy outcomes associated with maternal obesity. We have investigated the relation between pre-pregnancy BMI, B vitamin status, and inflammatory markers in a group of healthy pregnant women. Cobalamin, folate, pyridoxal 5'-phosphate, and riboflavin; and the metabolic markers homocysteine, methylmalonic acid, and 3-hydroxykynurenine/xanthurenic acid ratio (HK/XA); and markers of cellular inflammation, neopterin and kynurenine/tryptophan ratio (KTR) were determined in pregnancy week 18 and related to pre-pregnancy body mass index (BMI), in 2797 women from the Norwegian Mother and Child Cohort Study (MoBa). Pre-pregnancy BMI was inversely related to folate, cobalamin, pyridoxal 5'-phosphate (PLP), and riboflavin (p pregnancy BMI is a risk factor for low B vitamin status and increased cellular inflammation. As an optimal micronutrient status is vital for normal fetal development, the observed lower B vitamin levels may contribute to adverse pregnancy outcomes associated with maternal obesity and B vitamin status should be assessed in women with high BMI before they get pregnant.

    Subclinical hypothyroidism (SH) is associated with adverse obstetric outcomes and neurodevelopment disorders. Both iodine deficiency and excess are associated with SH; however, few data regarding iodine nutrition status of pregnant women with SH are available. This study aimed to clarify whether iodine deficiency or excess is associated with SH, especially, when test results for anti-thyroid autoantibodies are negative. A total of 115 women with SH and 104 women with euthyroidism (EH) in early pregnancy in Tianjin, China were investigated, and their serum thyroid-stimulating hormone, free thyroxine, free triiodothyronine, anti-thyroid peroxidase antibody (TPOAb), anti-thyroid globulin antibody (TGAb), urinary iodine (UIC), and urinary creatinine (UCr) concentrations were measured. Thyroid ultrasonography was performed to determine thyroid echogenicity and volume. The UIC, UIC/UCr ratio, prevalence of TPOAb and TGAb positivity, and thyroid gland volume were compared between the EH and SH groups. UIC and ultrasonographic features were analysed in subjects in the SH group who were negative for TPOAb and TGAb. Median UIC of SH (154.0 μg/L) and EH (150.1 μg/L) met the World Health Organization criterion for iodine sufficiency in pregnant women. Neither UIC nor the UIC/UCr ratio differed significantly between groups. The prevalence of TPOAb and TGAb positivity in the SH group was significantly higher than that in the EH group (P Women in early pregnancy with SH in Tianjin were iodine sufficient, but still at risk of iodine deficiency as pregnancy progressed. UIC ≥ 250 μg/L was associated with increased risk of SH. Serological negative autoimmune thyroiditis and UIC ≥ 250 μg/L may play a role in pathogenesis of SH cases with negative results for autoantibodies.

    Full Text Available Objective. This study aims to explore adolescents’ intentions related to the early formation of a family. Materials and methods. We administered a survey to students in eight schools in Morelos and Mexico City, in 2010. We analyzed intentions of marrying or having a child and fitted an exploratory path model to assess predictors of the intentions of having a child before the age of 20 (n=2974. Results. Around 77% of adolescents expect to have their first child at 20 years or later; 21% show ambivalence or incongruence regarding this, whereas 2% expect to have a child before the age of 20. Parents’ expectations for their child’s education influence the importance that adolescents give to education. The latter promotes the idea of postponing childbearing until 20 years or later (β=0.13. Conclusions. In order to prevent early pregnancies, interventions and programs should encourage the construction of personal and professional goals.

    Polycomb group (PcG) proteins are transcription regulatory proteins that control the expression of a variety of genes and the antero-posterior neural patterning from early embryogenesis. Although expression of PcG genes in the nervous system has been noticed, but the expression pattern of PcG proteins in early embryonic nervous system is still unclear. In this study, we analyzed the expression pattern of PRC1 complex members (BMI-1 and RING1B) and PRC2 complex members (EED, SUZ12 and EZH2) in early embryonic nervous system in mouse and human by Western blot and Immunohistochemistry. The results of Western blot showed that EED protein was significantly up-regulated with the increase of the day of pregnancy during the early embryogenesis in mouse. BMI-1 protein level was significantly increased from the day 10 of pregnancy, when compared with the day 9 of pregnancy. But the SUZ12, EZH2 and RING1B protein level did not change significantly. From the results of Immunohistochemistry, we found that the four PcG proteins were all expressed in the fetal brain and fetal spinal cord in mouse. In human, the expression of EED, SUZ12, and EZH2 was not significantly different in cerebral cortex and sacral spinal cord, but BMI-1 and RING1B expression was enhanced with the development of embryos in early pregnancy. Collectively, our findings showed that PRC1 and PRC2 were spatiotemporally expressed in brain and spinal cord of early embryos.

    To compare social and emotional adjustment including educational attainment and substance use in women who had a child, pregnancy termination, or miscarriage by young adulthood. Data were from a population-based longitudinal study of the health and well-being of 1,943 young Australians (Victorian Adolescent Health Cohort Study) followed from 15 to 24 years of age. The sample was restricted to female participants and based on pregnancies reported by age 24 years. Analyses were adjusted for early teenage depressive symptoms, cigarette smoking, alcohol use, cannabis use, and parent socioeconomic context. A total of 208 pregnancies (in 170 women) were reported from a sample of 824 young women by 24 years of age. Compared with those who had never been pregnant, those who had a child had lower tertiary education completion and a higher risk of nicotine dependence; those who terminated a pregnancy were more commonly single and had a higher risk of smoking and alcohol use as well as nicotine and alcohol dependence; and those who had a miscarriage had a higher risk of depressive symptomatology and binge drinking as well as nicotine and cannabis dependence. Young women who have been pregnant by their mid-twenties report a range of difficulties in social and emotional adjustment that vary across the different pregnancy outcomes. Broad-based psychosocial health care is essential not only for young women whose pregnancies proceed to live birth, but also for those whose pregnancies end with miscarriage or induced abortion.

    The association between vitamin D deficiency in the first trimester and GDM development remains controversial in various ethnicities. We prospectively assessed whether pregnant women with vitamin D deficiency during early pregnancy had an increased likelihood of GDM development or poor fetal growth or pregnancy outcomes compared to those with sufficient vitamin D levels. Serum 25-OH-D measurements and fetal ultrasonograms were carried out at 12-14, 20-22, and 32-34 wk in 523 pregnant women. Each woman was screened for GDM at 24-28 wk. There were no differences in serum 25-OH-D levels at 12-14 wk or 22-24 wk of pregnancy between GDM and non-GDM women after adjusting for maternal age, BMI at prepregnancy, BMI at first visit, BMI at GDM screening, gestational age at sampling, previous history of GDM, vitamin D intake, and seasonal variation in sampling. The risk of GDM, insulin resistance, and impaired β-cell function had no association with serum 25-OH-D levels in crude or adjusted logistic regression analysis. GDM was not associated with maternal serum 25-OH-D deficiency during the first trimester or fetal growth during the first and second trimesters. Pregnancy outcomes such as miscarriage, Apgar 1, Apgar 5 and birth weight were independent of maternal serum 25-OH-D levels during the first, second and third trimester of pregnancy. In conclusion, neither GDM prevalence nor fetal growth during pregnancy is associated with vitamin D deficiency at the first trimester in Korean women. Pregnancy outcomes are also independent of maternal vitamin D status.

    The purpose of this study was to examine the effectiveness of a professional support (PS) intervention (including individualized health education and supportive phone calls) in reducing the severity of nausea and vomiting (NV) and improving the quality of life (QOL) of women in early pregnancy. An experimental pretest/posttest design with a control group was used. Participants were recruited from a regional teaching hospital in southern Taiwan. The women in the experimental group (n = 40) received the PS intervention, while those in the control group (n = 39) only received routine nursing care. Analysis of covariance and mixed models were used to compare the experimental and control groups while adjusting for covariates. The severity of NV and the perceived level of symptom distress were significantly lower in the experimental group than in the control group during weeks 2 and 4, and the women in the experimental group showed a significant improvement in their QOL in week 4 (p < .05). However, there was no significant difference between the two groups in body weight at week 4 (p = .501). These findings provide empirical evidence in support of the effectiveness of PS in reducing the severity of NV and improving QOL for women during early pregnancy. This intervention could be routinely applied in prenatal nursing health education. Future studies could apply the concept of PS to different populations and health issues.

    Mefloquine (MQ) is a potent effective antimalarial drug against multiple drug-resistant Plasmodium falciparum. It has been proved that MQ can be given safely during the second and third trimesters. However, there is very limited information on the drug safety during the first trimester. The aim of the present work was to investigate the embryotoxicity and teratogenicity of MQ during critical periods of early development. Wistar rats were orally administered with a single dose of MQ (45 mg/kg bwt or 187 mg/kg bwt) on the 1st, 6th or 13th days of pregnancy. Cyclophosphamide (CPA) was chosen as a positive control. On the 21st day of gestation, standard parameters of reproductive performance and fetal examination were estimated. Malondialdehyde (MDA) level, glutathione reductase activity and glutathione (GSH) content were evaluated in placenta and liver homogenates of mothers and fetuses. The results indicated that MQ did not adversely affect the number of implantation, resorption, litter size and fetal body weight and length. Only groups treated with MQ on the 1st day of gestation exhibited significant decrease in fetal body weight. Examination of fetuses for external, visceral and skeletal changes showed minimal variations involving extension of lateral brain ventricles and renal pelvis and signs of delayed ossification. These variations were accompanied with significant elevation of MDA level and reduction of GSH content of fetal liver. Prenatal exposure to MQ at early pregnancy did not cause any embryolethal or teratogenic effect. It could slightly exacerbate minor variations.

  12. Environment and Climate of Early Human Evolution

    2015-05-01

    Evaluating the relationships between climate, the environment, and human traits is a key part of human origins research because changes in Earth's atmosphere, oceans, landscapes, and ecosystems over the past 10 Myr shaped the selection pressures experienced by early humans. In Africa, these relationships have been influenced by a combination of high-latitude ice distributions, sea surface temperatures, and low-latitude orbital forcing that resulted in large oscillations in vegetation and moisture availability that were modulated by local basin dynamics. The importance of both climate and tectonics in shaping African landscapes means that integrated views of the ecological, environmental, and tectonic histories of a region are necessary in order to understand the relationships between climate and human evolution.

  13. Postweaning Exposure to Dietary Zearalenone, a Mycotoxin, Promotes Premature Onset of Puberty and Disrupts Early Pregnancy Events in Female Mice

    Zearalenone (ZEA) is a mycotoxin commonly found in contaminated livestock feed and human food with levels in the range of ppb and low ppm. It was hypothesized that ZEA, an endocrine disruptor, could affect puberty and early pregnancy. To test this hypothesis, newly weaned (3 weeks old) C57BL/6J female mice were exposed to 0, 0.002, 4, 10, and 40 ppm ZEA and 0.05 ppm diethylstilbestrol (positive control) in phytoestrogen-free AIN-93G diet. Females exposed to 10 and 40 ppm ZEA diets showed earlier onset of vaginal opening. Those treated with 40 ppm ZEA diet also had earlier first copulation plug and irregular estrous cyclicity. At 8 weeks old, all females were mated with untreated stud males on AIN-93G diet during mating. Treatment resumed upon identification of a vaginal plug on gestation day 0.5 (D0.5). Embryo implantation was assessed on D4.5. Exposure to 40 ppm ZEA diet resulted in reduced percentage of plugged mice with implantation sites, distended uterine appearance, and retained expression of progesterone receptor in D4.5 uterine epithelium. To determine the exposure timing and mechanisms of disrupted embryo implantation, four groups of females were fed with 0 or 40 ppm ZEA diets during premating (weaning to mating) and postmating (D0.5–D4.5), respectively. Premating exposure to 40 ppm ZEA diet reduced fertilization rate, whereas postmating exposure to 40 ppm ZEA diet delayed embryo transport and preimplantation embryo development, which subsequently affected embryo implantation. These data demonstrate that postweaning exposure to dietary ZEA can promote premature onset of puberty and disrupt early pregnancy events. PMID:23291560

    Human chorionic gonadotropin (hCG) is an essential hormone for development and sustaining of gestation. Adequate hCG production is fundamental for pregnancy success since abnormal hCG serum concentrations have been correlated with pregnancy anomalies such as recurrent abortions and preeclampsia. Regulation of hCG production involves diverse molecules associated with different signaling pathways, which have complicated the establishment of the mechanisms involved in its production. The present study provides a critical review of the most relevant findings related to hCG production and functions during pregnancy, in order to help to understand some related pathologies and to treat them more adequately.

    Pregnancy at early, but not late age, has a strong and life-long protective effect against breast cancer. The expected overall increase in breast cancer incidence demands the development of a pharmaceutical mimicry of early-age pregnancy-mediated protection. Recently, converging results from rodent models and women on molecular and cellular mechanisms underlying the protective effect of early-age pregnancy have opened the door for translational studies on pharmacologic prevention against breast cancer. In particular, alterations in Wnt and TGFβ signaling in mammary stem/progenitor cells reveal new potential targets for preventive interventions, and thus might help to significantly reduce the incidence of breast cancer in the future. ©2015 American Association for Cancer Research.

    To investigate whether the cervical length measured by transvaginal ultrasound at 35 to 36 weeks of gestation is predictive of spontaneous early onset of labor in pregnancies scheduled for elective cesarean section (CS). This was a prospective observational study on 167 women scheduled for elective CS at 39 weeks of gestation. The cervical length was measured ultrasonographycally at 35 to 36 weeks of gestation and the pregnancies characteristics were recorded. The presence or absence of spontaneous onset of labor before the time scheduled for elective CS was related to cervical length and pregnancies characteristics. Of the 167 pregnancies enrolled, 25 (14.97%) underwent early spontaneous onset of labor before the time scheduled for the elective CS. The cervical length was significantly shorter in these women when compared with those delivering with an elective CS (21 vs. 30 mm z=5.49 Ponset of labor in univariate analysis (P=0.01). Multivariate logistic regression analysis showed that cervical length (adjusted odds ratio 1.40; 95% confidence interval (CI) 1.22-1.61; P≤0.0001) was the only predictor for the early onset of labor. The area under the receiver-operating characteristics curve for the prediction of early onset of labor was 0.844 (95% CI 0.738-0.950) for cervical length as test variable. Kaplan-Meier analysis demonstrated that a cervical length onset of labor in pregnancies scheduled for CS and may be useful in individualizing the gestational age for elective CS.

    Full Text Available Failure to detect pregnancy in the emergency situations can have important consequences. These include missing of ectopic pregnancy (the leading cause of first-trimester pregnancy-related maternal death, administration of medications contraindicated in pregnancy, fetal radiation exposure, and medico legal problems. This in turn has led to the dictum to check for pregnancy in all women of child-bearing age group. Urine pregnancy (human chorionic gonadotropin [hCG] test is the commonly used test to rule out pregnancy and has been reported by Griffey et al. in their study to achieve 100% sensitivity and 99.2% specificity in a clinical setting, resulting in a positive predictive value of 98.3% and a negative predictive value of nearly 100%. However, the sensitivity is influenced not only by the quantity of β hCG but on its variants that vary with different weeks of pregnancy. β hCG is present in several variant forms that change in their concentrations at different stages of pregnancy. In spite of its high sensitivity, in the presence of molar pregnancy that is associated with very high levels of β hCG it fails to detect the antigen (β hCG. This is explained by the phenomenon known as "high-dose hook effect" which further leads to delay in diagnosis and treatment. This can be overcome by dilution of the sample. In such cases, diagnosis will be made by serum β hCG and ultrasound (USG. Here, we present a case of gravida 2 para 1 living 1 with 2΍ months amenorrhea with bleeding p/v and pain abdomen of 20 days duration whose urine β hCG was repeatedly negative and diagnosis was made by serum β hCG and USG.

    Low vitamin D levels during pregnancy may have negative consequences for the health of both the mother and child. Cross-sectional studies in childbearing women suggest that vitamin D levels are low during pregnancy, but few studies have followed the same women during pregnancy and postpartum. The aims of this study were to longitudinally assess vitamin D status during pregnancy and postpartum and identify the factors associated with vitamin D status in pregnant women in northern Sweden. Between September 2006 and March 2009, 184 women were consecutively recruited at five antenatal primary care clinics. Blood was sampled, and dietary intake was estimated using a food frequency questionnaire with 66 food items/food aggregates and questions on the intake of vitamin supplements at gestational weeks 12, 21, and 35, as well as at 12 and 29 weeks after birth. Plasma 25(OH) vitamin D levels were analyzed using liquid chromatography tandem-mass spectrometry. At least one-third of the women had 25(OH) vitamin D levels pregnancy. The levels reverted to the baseline levels after birth. Multivariate analysis showed that gestational and postpartum week, season, dietary intake of vitamin D, and vitamin supplementation were significantly related to plasma levels. There was also an influence of season on the longitudinal concentration patterns. In conclusion, more than one-third of the women studied had low 25(OH) vitamin D levels, and gestational and postpartum week was related to 25(OH) vitamin D levels after adjustment for season and vitamin D intake.

    With the advancement of ultrasonic technology in recent years, sonography has become a common medical diagnostic tool, as it has elevated output sonic intensity and elongated exposure time. This study investigates the effect of ultrasound on human chorionic villus cell apoptosis during early pregnancy. Transvaginal ultrasound was performed for a total of 60 women who had undergone induced abortion at our hospital. They were randomly divided into the control, short ultrasound (10 min), and long ultrasound (20 min) groups (N = 20 each). Twenty-four hours after ultrasonic exposure, chorionic villus tissues were extracted during induced abortion, and were tested for cell apoptosis using flow cytometry. Bax and B cell lymphoma-2 (Bcl-2) protein levels were also quantified by immunohistochemistry. We found that the long ultrasound group had significantly higher cell apoptosis rates compared to the short ultrasound group, which in turn had higher rates compared to the control group (P ultrasound groups (P ultrasound groups, however, were downregulated as compared to those in the control group (P < 0.05). It is therefore possible that transvaginal sonography can potentiate the apoptosis of human chorionic villus cells by increasing the Bax/Bcl-2 protein ratio.

    Concerns about the increasing rates of obesity in developing countries have led many policy makers to question the impacts of maternal and early child nutrition on risk of later obesity. The purposes of the review are to summarise the studies on the associations between nutrition during pregnancy and infant feeding practices with later obesity from childhood through adulthood and to identify potential ways for preventing obesity in developing countries. As few studies were identified in developing countries, key studies in developed countries were included in the review. Poor prenatal dietary intakes of energy, protein and micronutrients were shown to be associated with increased risk of adult obesity in offspring. Female offspring seem to be more vulnerable than male offspring when their mothers receive insufficient energy during pregnancy. By influencing birthweight, optimal prenatal nutrition might reduce the risk of obesity in adults. While normal birthweights (2500-3999 g) were associated with higher body mass index (BMI) as adults, they generally were associated with higher fat-free mass and lower fat mass compared with low birthweights (obesity in adults. Breastfeeding and timely introduction of complementary foods were shown to protect against obesity later in life in observational studies. High-protein intake during early childhood however was associated with higher body fat mass and obesity in adulthood. In developed countries, increased weight gain during the first 2 years of life was associated with a higher BMI in adulthood. However, recent studies in developing countries showed that higher BMI was more related to greater lean body mass than fat mass. It appears that increased length at 2 years of age was positively associated with height, weight and fat-free mass, and was only weakly associated with fat mass. The protective associations between breastfeeding and obesity may differ in developing countries compared to developed countries because many

    Thyroid peroxidase antibodies (TPOAb) in pregnancy are a marker for postpartum (PPTD) and long-term thyroid dysfunction, with variable sensitivity and specificity in PPTD prediction. To test its utility in prediction, we recruited 308 TPOAb-positive (147 developed PPTD (PPTD group) and 161 remained euthyroid [PPTE group]) and 102 TPOAb-negative women (none developed PPTD), in early pregnancy (median, 18; range, 9-19 weeks' gestation). TPOAb levels were higher in the PPTD group (median) (125.2 kIU/L; p < 0.001), and in its hypothyroid (162.4 kIU.; p < 0.0001), hyperthyroid (114.2 kIU/L; p < 0.007), and biphasic (105.1 kIU/L; p < 0.02) variants, compared to the PPTE group (66.7 kIU/L) The incidence of PPTD was significantly higher with TPOAb levels above 58.2 kIU/L (early pregnancy versus postpartum; relative risk, 1.37 [95% confidence interval [CI] 1.17-1.61] versus 0.78 [95% CI 0.5-1.2]) compared to levels below. The integrated postpartum TPOAb response was higher in the PPTD group (median) (159 kIU/L per week) and its variants (hypothyroid; 199 kIU/L per week; biphasic, 180 kIU/L per week; hyperthyroid, 120 kIU/L per week), compared to the PPTE group (86 kIU/L per week p < 0.004). Median early pregnancy TPOAb levels in the PPTD and PPTE groups correlated well with the postpartum antibody response (r = 0.58, p < 0.001). The sensitivity of TPOAb in PPTD prediction was 100% (early pregnancy and postpartum), specificity 62% (early pregnancy) versus 41% (postpartum) and positive predictive value 48% (early pregnancy and postpartum). The timing of TPOAb testing, the sensitive assay used and the absence of PPTD in TPOAb-negative subjects contributed to this high sensitivity. We recommend TPOAb in early pregnancy as a useful predictor of PPTD, particularly in populations where PPTD does not occur in TPOAb-negative women.

    We investigated the expression of methyl transferase G9a and methylated histone H3-K9 in fresh human decidual/endometrial tissue of 12 normal early pregnancies and 15 unexplained recurrent spontaneous abortions (URSA). The samples were obtained through dilatation and curettage and collected as per strict inclusion-exclusion criteria. The tissue was subjected to immunohistochemical analysis (IHC), western blotting (WB) and RT-PCR analysis. The results demonstrated methyl transferase G9a to have a lower expression in abortions when compared with that in normal pregnancy (P K9 was significantly lower (P < 0.0001) in URSA tissues than in controls. This study suggests that methylation may cause URSA and indicates the need for further work to explore the role of methylation in URSA and its possible prevention through locally acting methylating/demethylating agents.

    Maternal thyroid dysfunction in early pregnancy may increase the risk of adverse pregnancy complications and neurocognitive deficiencies in the developing fetus. Currently, some researchers demonstrated that body mass index (BMI) is associated with thyroid function in nonpregnant population. Hence, the American Thyroid Association recommended screening thyroid function in obese pregnant women; however, the evidence for this is weak. For this purpose, our study investigated the relationship between high BMI and thyroid functions during early pregnancy in Liaoning province, an iodine-sufficient region of China. Serum thyroid stimulating hormone (TSH), free thyroxine (FT4), thyroid-peroxidase antibody (TPOAb), thyroglobulin antibody (TgAb) concentration, urinary iodine concentration (UIC), and BMI were determined in 6303 pregnant women. BMI ≥ 25 kg/m(2) may act as an indicator of hypothyroxinemia and TPOAb positivity and BMI ≥ 30 kg/m(2) was associated with increases in the odds of hypothyroidism, hypothyroxinemia, and TPOAb positivity. The prevalence of isolated hypothyroxinemia increased among pregnant women with BMI > 24 kg/m(2). High BMI during early pregnancy may be an indicator of maternal thyroid dysfunction; for Asian women whose BMI > 24 kg/m(2) and who are within 8 weeks of pregnancy, thyroid functions should be assessed especially.

    China is a key area for probing into human occupation in the Old World after the initial expansion of early humans out of Africa. Chronology of Chinese Paleolithic/hominin sites in different paleoclimatic and paleoenvironmental settings is paramount for understanding early human migration and adaptation. In recent years, we conducted detailed magnetostratigraphic investigations on the Nihewan Basin in temperate northern China and the Yuanmou Basin in subtropical southern China, both of which contained abundant sites of early humans and mammalian faunas. The age of the sedimentary sequence of the eastern Nihewan Basin can be magnetostratigraphically constrained to an interval from late Pliocene to late Pleistocene. The basal age of the Nihewan Formation in the eastern basin is constrained just prior to the Gauss-Matuyama geomagnetic reversal, that is, between ~2.6 Ma and ~3.0 Ma. The fluvio-lacustrine sequences in this basin were deposited from the late Gauss chron into the late Brunhes chron, and are capped by the last interglacial soil and the last glacial loess , or by the late Pleistocene or Holocene loess sediments. As a result, the Nihewan faunas (sensu lato) can be placed between the Matuyama-Brunhes geomagnetic reversal and the onset of the Olduvai subchron (0.78-1.95 Ma), and a robust chronological sequence of early human colonization in this basin has been established: Maliang (0.8 Ma), Huojiadi (1.0 Ma), Donggutuo and Cenjiawan (1.1 Ma), Feiliang (1.2 Ma), Banshan (1.32 Ma), Xiaochangliang and Xiantai (1.36 Ma), MJG-I (1.55 Ma), MJG-II (1.64 Ma), and MJG-III (1.66 Ma). The age of the sedimentary sequence of the Yuanmou Basin can be magnetostratigraphically constrained to an interval from early Pliocene to Pleistocene. The basal age of this basin sedimentary sequence is constrained just prior to the onset of the Sidufjall subchron, that is, ~4.9 Ma. Accumulation of the Yuanmou sequence was terminated during the Matuyama chron bracketed by the Olduvai and

    Preeclampsia (PE) is a pregnancy-specific disorder, defined as new onset of maternal hypertension and proteinuria after 20 weeks of gestation. Our earlier study has shown increased maternal oxidative stress at delivery to be associated with poor birth outcome in PE. However, these results were observed when the pathology had progressed and may have been secondary to the effects of the disorder. To understand the role of antioxidant defense mechanisms in PE right from early pregnancy, in this prospective study, we measured malondialdehyde (MDA), superoxide dismutase (SOD), glutathione peroxidase (GPx) and glutathione (GSH) concentrations in maternal blood at 3 time-points of gestation [16-20 weeks (T1), 26-30 weeks (T2), at delivery (T3)] and in cord blood. Gene expression of SOD and GPx and protein levels of endothelial nitric oxide synthase (eNOS) enzyme were also analyzed in the placenta. MDA levels were higher at T1 (p stress right from 16 to 20 weeks of gestation. This may alter placental development and lead to fetal programming of adult non-communicable disease in the offspring.

    There are few established causes of leukemia, the most common type of cancer in children. Studies in adults suggest a role for specific environmental agents, but little is known about any effect from exposures in pregnancy to toxics in ambient air. In our case-control study, we ascertained 69 cases of acute lymphoblastic leukemia (ALL) and 46 cases of acute myeloid leukemia (AML) from California Cancer Registry records of children leukemia associated with one interquartile range increase in air toxic exposure. Risk of ALL was elevated with 3(rd) trimester exposure to polycyclic aromatic hydrocarbons (OR=1.16, 95% CI 1.04, 1.29), arsenic (OR=1.33, 95% CI 1.02, 1.73), benzene (OR=1.50, 95% CI 1.08, 2.09), and three other toxics related to fuel combustion. Risk of AML was increased with 3rd trimester exposure to chloroform (OR=1.30, 95% CI 1.00, 1.69), benzene (1.75, 95% CI 1.04, 2.93), and two other traffic-related toxics. During the child's first year, exposure to butadiene, ortho-xylene, and toluene increased risk for AML and exposure to selenium increased risk for ALL. Benzene is an established cause of leukemia in adults; this study supports that ambient exposures to this and other chemicals in pregnancy and early life may also increase leukemia risk in children.

    While associations of vitamin D deficiency with type 2 diabetes have been well demonstrated, investigations of vitamin D and risk of gestational diabetes mellitus (GDM) reported inconsistent findings. We examined associations of vitamin D status with GDM. In a nested case-cohort study (135 GDM cases and 517 non-GDM controls), we measured maternal serum vitamin D status (total 25[OH]D and 25[OH]D3 ) in early pregnancy (16 weeks on average) using liquid chromatography-tandem mass spectroscopy. GDM was diagnosed according to the American Diabetes Association guidelines. We calculated adjusted odds ratios and 95% confidence intervals (CIs) using logistic regression models. GDM cases had lower mean total 25[OH]D (27.3 vs. 29.3 ng/mL) and 25[OH]D3 (23.9 vs. 26.7 ng/mL) concentrations compared with women who did not develop GDM (both P-values pregnancy vitamin D status, particularly 25[OH]D3 , is inversely associated with GDM risk. © 2015 John Wiley & Sons Ltd.

    Data surrounding the use of a random urine protein:creatinine ratio (PCR) in the diagnosis of preeclampsia is conflicting. We sought to determine whether PCR in early pregnancy can replace the 24-hour urine collection as the primary screening test in patients at risk for baseline proteinuria. Women requiring a baseline evaluation for proteinuria supplied a urine sample the morning after their 24-hour collection. The PCR was analyzed as a predictor of significant proteinuria (≥150 mg). A regression equation to estimate the 24-hour protein value from the PCR was then developed. Sixty of 135 subjects enrolled completed the study. The median 24-hour urine protein and PCR were 90 mg (IQR: 50-145) and 0.063 (IQR: 0.039-0.083), respectively. Fifteen patients (25%) had significant proteinuria. PCR was strongly correlated with the 24-hour protein value (r = 0.99, p proteinuria (AUC = 0.86). A PCR cut-point of 0.079 yielded a sensitivity of 93.3% and a specificity of 57.8%. The resulting regression equation [total protein = 46.5 + 904.2*PCR] accurately estimates the actual 24-hour protein (95% CI: ±88 mg). A random urine PCR accurately estimates the 24-hour protein excretion in the first half of pregnancy and can be used as the primary screening test for baseline proteinuria in at-risk patients.

    Directory of Open Access Journals (Sweden)

    Patrícia El Beitune

    Full Text Available Women have emerged as the fastest growing human immunodeficiency virus (HIV infected population worldwide, mainly because of the increasing occurrence of heterosexual transmission. Most infected women are of reproductive age and one of the greatest concerns for both women and their physicians is that more than 1,600 infants become infected with HIV each day. Almost all infections are a result of mother-to-child transmission of HIV. With the advent of combination antiretroviral therapies, transmission rates lower than 2% have been achieved in clinical studies. Antiretroviral compounds differ from most other new pharmaceutical agents in that they have become widely prescribed in pregnancy in the absence of proof of safety. We reviewed antiretroviral agents used in pregnant women infected with human immunodeficiency virus, mother-to-child transmission, and their consequences for infants.

    Observational studies have shown an increased lifetime risk of cardiovascular disease (CVD) in women who experienced a hypertensive disorder in pregnancy. This risk is related to the severity of the pregnancy-related hypertensive disease and gestational age at onset. However, it has not been investigated whether these differences in CVD risk factors are already present at postpartum cardiovascular screening. We evaluated postpartum differences in CVD risk factors in 3 subgroups of patients with a history of hypertensive pregnancy. We compared the prevalence of common CVD risk factors postpartum among 448 women with previous early-onset preeclampsia, 76 women with previous late-onset preeclampsia, and 224 women with previous pregnancy-induced hypertension. Women with previous early-onset preeclampsia were compared with women with late-onset preeclampsia and pregnancy-induced hypertension and had significantly higher fasting blood glucose (5.29 versus 4.80 and 4.83 mmol/L), insulin (9.12 versus 6.31 and 6.7 uIU/L), triglycerides (1.32 versus 1.02 and 0.97 mmol/L), and total cholesterol (5.14 versus 4.73 and 4.73 mmol/L). Almost half of the early-onset preeclampsia women had developed hypertension, as opposed to 39% and 25% of women in the pregnancy-induced hypertension and late-onset preeclampsia groups, respectively. Our data show differences in the prevalence of common modifiable CVD risk factors postpartum and suggest that prevention strategies should be stratified according to severity and gestational age of onset for the hypertensive disorders of pregnancy.

    Plasma HCS levels have been measured in normal and pathological pregnant women. In the normal group HCS levels increased from 6--8 weeks till 33-34 weeks and then felt significantly. HCS pattern in prediabetic and chemical diabetic pregnant women was similar to the normal group. However HCS levels in chemical diabetics were significantly higher during the first two trimesters. HCS levels increased in twin pregnancy, diminished in cases of eclampsia, hypertension, fetal growth retardation, mole and blighted ovum, and disappeared after intrauterine death. Nothing could be deduced from the obese and Rh-isoimmunization groups. It is confirmed the value of HCS determination as an index of placental maturation. Also, insulin/HCS ratio may be of some aid in the study of carbohydrate intolerance in pregnancy.

    T helper 17 (TH17) cells have been identified as a new lineage of helper T cells and have been shown to be important in host defense against extracellular infectious agents, autoimmune disease and chronic inflammatory diseases. Recently, TH17 cells have also been shown to participate in successful pregnancy, as well as in the pathogenesis of diseases of pregnancy, such as recurrent spontaneous abortion (RSA) and pre-eclampsia (PE). Here, we review our current knowledge of TH17 cells in human RSA and PE. We also discuss how the local uterine microenvironment affects the differentiation of TH17 cells and the mechanisms that regulate TH17 cells during pregnancy. Research into TH17 cells will not only advance our understanding of TH17-related pregnancy complications, but will also facilitate the design of novel therapies for reproductive diseases.

    Abstract Although epidemiological studies suggest that offspring of women with preeclampsia are at increased risk to higher blood pressures and cardiovascular disease, little is known about the nature of blood pressures between the mother and her offspring. As blood pressures comprise of both pulsatile (systolic blood pressure [SBP] and pulse pressure [PP]) and stable (diastolic blood pressure [DBP]) components, and they differ between central and peripheral sites, we sought to examine maternal peripheral and central blood pressure components in relation to offspring early childhood blood pressures. A prospective birth cohort of 567 Chinese, Malay, and Indian mother–offspring with complete blood pressure information were studied. Maternal brachial artery SBP, DBP, and PP were measured at 26 to 28 weeks gestation; and central SBP and PP were estimated from radial artery waveforms. Offspring brachial artery SBP, DBP, and PP were measured at 3 years of age. Associations between continuous variables of maternal blood pressures (peripheral SBP, DBP, PP, central SBP, and PP) and offspring blood pressures (peripheral SBP, DBP, and PP) were examined using multiple linear regression with adjustment for maternal characteristics (age, education level, parity, smoking status, alcohol consumption and physical activity during pregnancy, and pre-pregnancy BMI) and offspring characteristics (sex, ethnicity, BMI, and height at 3 years of age). In the multivariate models, offspring peripheral SBP increased by 0.08 (95% confidence interval 0.00–0.17, P = 0.06) mmHg with every 1-mmHg increase in maternal central SBP, and offspring peripheral PP increased by 0.10 (0.01–0.18, P = 0.03) mmHg for every 1-mmHg increase in maternal central PP. The relations of maternal-offspring peripheral blood pressures (SBP, DBP, and PP) were positive but not statistically significant, and the corresponding values were 0.05 (−0.03 to 0.13; P = 0.21), 0.03 (−0.04 to 0.10; P = 0

    Background: The maternal cardiovascular system undergoes progressive adaptations throughout pregnancy, causing blood pressure fluctuations. However, no consensus has been established on its normal variation in uncomplicated pregnancies. Objective: To describe the variation in systolic blood pressure (SBP) and diastolic blood pressure (DBP) levels during pregnancy according to early pregnancy body mass index (BMI). Methods: SBP and DBP were measured during the first, second and third trimesters and at 30-45 days postpartum in a prospective cohort of 189 women aged 20-40 years. BMI (kg/m2) was measured up to the 13th gestational week and classified as normal-weight (parto imediato segundo o índice de massa corporal (IMC) no início da gravidez. Métodos: A PAS e a PAD foram medidas no 1º, 2º e 3º trimestres gestacionais e aos 30-45 dias pós-parto em uma coorte prospectiva de 189 mulheres com idade entre 20 e 40 anos. O IMC (kg/m2) foi aferido até a 13a semana e classificado como normal (parto (βPAS=0,010; IC95%:0,006-0,014 e βPAD=0,015; IC95%:0,012-0,018). As mulheres com IMC excessivo apresentaram média de PAS maior em todos os trimestres, e de PAD maior no primeiro e no terceiro trimestres. O IMC excessivo no início da gestação esteve positivamente associado com mudanças na PAS (βPAS=7,055; IC95%:4,499-9,610) e na PAD (βPAD=3,201; IC95%:1,136-5,266). Conclusão: A PAS e a PAD diminuíram do primeiro para o segundo trimestre e aumentaram do segundo trimestre até o pósparto. Mulheres com IMC excessivo no início da gestação apresentaram valores mais elevados de PAS e PAD ao longo da gravidez, mas não no pós-parto, quando comparadas às de IMC normal.

    Full Text Available The aim of present study was to determine the distributions of proliferating cell nuclear agent (PCNA and Cas-pase-3 (Cas-3 and their possible roles in implantation and decidualization during early pregnancy at immunohistochemical level. The tissue samples from pregnant animals between gestational days 1-5 were incubated by PCNA and Cas-3 antibodies and the obtained results were evaluated quantitatively. It was observed that PCNA immunoreactivity in uterine luminal epithelium and glandular epithelium reduced as from day 2 of gestation and disappeared as from day 4 of gestation. PCNA staining intensity in stromal cells and myometrium increased gradually with progressing gestation. While Cas-3 immunoreactivity was strongly detected in luminal and glandular epithelium throughout the whole gestational period, its reactivity markedly increased as from day 3 of gestation. In conclusion, it may suggest that the blastocyst implantation induces the uterine luminal epithelial cell death and stromal cell proliferation around the embryo in the uterus.

    The chorionic cavity, vertex-breech length, yolk sac, and amnion were systematically demonstrated and measured in 50 early pregnancies, i.e., between the end of the sixth and the tenth week of gestation post menstruationem (p.m.). This was done in 23 cases with clinically and sonographically intact pregnancies without symptoms of abortion, in 12 cases with living embryos with symptoms of abortion, and in 15 cases of retained miscarriage. The thin amniotic membrane is sonographically demonstrated as a narrow, sharply defined reflected band in the chorionic cavity. In addition to direct demonstration of the amniotic membrane, the amniotic cavity can be demonstrated by a density difference in the echogenicity of the chorionic and amniotic fluids. While there are delicate, homogenously distributed inner echoes in the chorionic cavity, the amniotic cavity is empty save for the embryo structure. Sonographically, therefore, the amniotic cavity stands out as a spherical structure within the chorionic cavity. In all pregnancies with a living embryo it was possible to demonstrate the yolk sac sonographically as a sharply defined ring structure in the chorionic cavity. In 10 of the 15 cases of retained miscarriage only a rudimentary remnant of the yolk sac could be detected. The development of the amniotic and chorionic cavities and vertex-breech length was constant in the pregnancies with living embryos, the amnion developing synchronously with the vertex-breech length.(ABSTRACT TRUNCATED AT 250 WORDS)

    To evaluate the construct validity and factor structure of the Spanish-language version of the Ford Insomnia Response to Stress Test questionnaire (FIRST-S) when used in early pregnancy. A cohort of 647 women were interviewed at ≤ 16 weeks of gestation to collect information regarding lifestyle, demographic, and sleep characteristics. The factorial structure of the FIRST-S was tested through exploratory and confirmatory factor analyses (EFA and CFA). Internal consistency and construct validity were also assessed by evaluating the association between the FIRST-S with symptoms of depression, anxiety, and sleep quality. Item response theory (IRT) analyses were conducted to complement classical test theory (CTT) analytic approaches. The mean score of the FIRST-S was 13.8 (range: 9-33). The results of the EFA showed that the FIRST-S contained a one-factor solution that accounted for 69.8% of the variance. The FIRST-S items showed good internal consistency (Cronbach α = 0.81). CFA results corroborated the one-factor structure finding from the EFA; and yielded measures indicating goodness of fit (comparative fit index of 0.902) and accuracy (root mean square error of approximation of 0.057). The FIRST-S had good construct validity as demonstrated by statistically significant associations of FIRST-S scores with sleep quality, antepartum depression and anxiety symptoms. Finally, results from IRT analyses suggested excellent item infit and outfit measures. The FIRST-S was found to have good construct validity and internal consistency for assessing vulnerability to insomnia during early pregnancy. © 2016 American Academy of Sleep Medicine.

    Full Text Available Aim: To asses the efficacy of screening thyroid function during early pregnancy. Material and Method: One hundred and eighty five pregnant women who attended a secondary center for their first antenatal visits (6-12 weeks of gestation between May 2012 and August 2012 were divided into two groups comprising 94 women regarded as high-risk and 91 low-risk. Maternal serum concentrations of TSH, fT4 and fT3 were measured. The thyroid function of the study group was evaluated for euthyroidism, hypothyroidism, hyperthyroidism, subclinical hypothyroidism, and subclinical hyperthyroidism according to TSH, fT3 and fT4 results. Analysis of data were performed, using the SPSS software version 11.5. In all tests, p<0.05 was accepted as statistically significant. Results: We screened thyroid function in 185 pregnant women, of whom 151 (81.62% were euthyroid and 34 (18.38%  had thyroid dysfunction, with 24 (12.98% in the high-risk group and 10 (5.4% in the low-risk group. When the results of thyroid function tests were evaluated as normal and abnormal, the most statistically significant characteristics for abnormal results were found to be history of antithyroid therapy and thyroid surgery (p=0.005, p=0.015. We would fail to spot about one third of thyroid dysfunctions if only high-risk women were screened. Discussion: Risk-stratified screening for maternal thyroid dysfunction during early pregnancy may led to neglected diagnoses of thyroid disorders. Results here indicated universal screening, but the debate regarding the targeting of high-risk cases seems set to continue into the future.

    Emerging evidence has suggested that folic acid-containing multivitamins may markedly reduce the risk of gestational hypertension or preeclampsia. We examined whether maternal supplementation with folic acid alone during early pregnancy can prevent the occurrence of gestational hypertension and preeclampsia. The data are from a large population-based cohort study established to evaluate the effectiveness of the campaign to prevent neural tube defects with folic acid supplementation in China. We selected participants who were registered in 2 southern provinces, had exact information on folic acid use, and were not affected by chronic hypertension or diabetes mellitus before 20 weeks gestation. A logistic regression model was used to adjust for the effects of the main potential confounders, including age, body mass index, education, occupation, parity, and multiple births. The study size had 99.9% power (α=0.05) to detect a decrease of 10% over the unexposed rate of 9.4% for gestational hypertension. Among the 193 554 women (47.9% took folic acid, 52.1% did not), the overall incidence of gestational hypertension and preeclampsia was 9.5% and 2.5%, respectively. The incidence of gestational hypertension and preeclampsia was 9.7% and 2.5% for women who took folic acid, and 9.4% and 2.4% for women who did not use it. The adjusted risk ratio associated with folic acid use was 1.08 (95% confidence interval, 1.04-1.11) for gestational hypertension and 1.11 (95% confidence interval, 1.04-1.18) for preeclampsia. Our findings suggest that daily consumption of 400 μg folic acid alone during early pregnancy cannot prevent the occurrence of gestational hypertension and preeclampsia.

    Full Text Available In four Kenyan pig breeding units the pregnancy diagnosis of sows has been carried out in two groups: Group 1 (n = 1911: the sows were transrectaly pregnancy tested between Days 17–22 post-mating by ultrasound. Sows testing non-pregnant immediately received one dose of 400 IU pregnant mare serum gonadotropin (PMSG (equine chorion gonadotropin, eCG and 200 IU human chorion gonadotropin (hCG. On showing signs of oestrous, the animals were subsequently artificially inseminated (AI. Group 2 (n = 1923: sows were pregnancy tested by serum progesterone (P4-based enzyme-linked immunosorbent assay (ELISA on Day 17 post-breeding. P4 concentrations were categorized as positive (> 5 ng/ml or negative (< 5 ng/ml. Sows testing non-pregnant immediately received one dose of 400 IU PMSG and 200 IU hCG by injection, and were subsequently artificially inseminated. The following parameters were evaluated: sows diagnosed non-pregnant, days from first post-weaning insemination until the sows were inseminated at their first return to oestrus; farrowing rate and total piglets born and number of live-born piglets in litters.The percentage of sows diagnosed non-pregnant in the two groups, as well as the totals of born piglets and of live-born piglets in litters did not differ significantly between the two groups. The number of days from the first post-weaning mating until the sows were artificially inseminated at their first return to oestrus and the administration of eCG and hCG was shorter (P < 0.01 and farrowing rate was higher (P < 0.01 in the ELISA-tested sows.

    China is a key area for research into human occupation in the Old World after the initial expansion of early humans out of Africa. Reliable age determinations are pivotal for assessing the patterns of human evolution and dispersal in this region. This paper reviews magnetostratigraphic studies of some early Pleistocene strata bearing hominin remains and/or artifact stone tools from northern to southern China. The quality and reliability of the paleomagnetic dates are also evaluated. New magnetostratigraphic results for the Xihoudu Paleolithic site in north-central China are also presented. Among the few hominin or Paleolithic sites in China from the early Pleistocene, five have been well investigated. Three of these are in northern China at Xiaochangliang, Donggutuo and Gongwangling; the remaining two in southern China at Longgupo and Yuanmou. Considerable progress has been made during the past three decades towards paleomagnetically dating these sites. Indeed, the age estimates at Xiaochangliang and Gongwangling have been widely accepted. Magnetostratigraphic consensus about the age of the Donggutuo site has also been reached. However, the age determination for the two sites in southern China is still contested. The integration of rock-magnetic stratigraphy with magnetic polarity stratigraphy has resulted in a determined age of 1.36 Ma for a stone tool-containing layer of lacustrine sediments at the Xiaochangliang site in the Nihewan Basin. Lithostratigraphic constraints have significantly contributed to determining the age of Lantian Homo erectus at Gongwangling, which occurred in a loess-paleosol sequence of the southern Loess Plateau. Its age, paleomagnetically derived, is about 1.15 Ma. These two paleomagnetic ages suggest an expansion and flourishing of human groups from northern to north-central China during the early Pleistocene. This suggestion has been reinforced by our new magnetostratigraphic age estimate of about 1.27 Ma for the Xihoudu site as will be

    Subclinical hypothyroidism is common in pregnant women and often related to adverse pregnancy outcomes, but its relationship with gestational diabetes remains controversial. In particular, the impact of thyroperoxidase antibodies status on the relationship between subclinical hypothyroidism and gestational diabetes is not clear. We investigated the association between combined thyroid stimulating hormone (TSH) level and thyroperoxidase antibodies status in early pregnancy (diabetes mellitus. A total of 7084 pregnant women met the inclusion criteria, which included thyroperoxidase antibodies-positive subclinical hypothyroidism [TSH(H)TPOAb(+)] (n = 78), thyroperoxidase antibodies-negative subclinical hypothyroidism [TSH(H)TPOAb(-)] (n = 281), thyroperoxidase antibodies-positive euthyroidism [TSH(N)TPOAb(+)] (n = 648), and thyroperoxidase antibodies-negative euthyroidism [TSH(N)TPOAb(-)] (n = 6077). Of the 7084 cases included in our study, 1141 cases were diagnosed with gestational diabetes mellitus at 24-28 weeks of pregnancy. The prevalence of gestational diabetes mellitus in TSH(N)TPOAb(-), TSH(H)TPOAb(-), TSH(N)TPOAb(+), and TSH(H)TPOAb(+) was 14.65, 19.57, 24.85, and 46.15 %, respectively. Compared with TSH(N)TPOAb(-) women, the risk of gestational diabetes mellitus was increased in all other groups of women in early pregnancy. After dividing early pregnancy into first and second trimesters, we found that TSH(H)TPOAb(-) women in the first trimester do not show this increase. Our study suggests that subclinical hypothyroidism and thyroperoxidase antibodies-positive euthyroidism in early pregnancy are associated with an increased risk of gestational diabetes mellitus.

    Full Text Available Abstract Background Childhood obesity is on the rise and is a major risk factor for type 2 diabetes later in life. Recent evidence indicates that abnormalities that increase risk for diabetes may be initiated early in infancy. Since the offspring of women with diabetes have an increased long-term risk for obesity and type 2 diabetes, the impact of maternal metabolic abnormalities on early nutrition and infant metabolic trajectories is of considerable interest. Human breast milk, the preferred food during infancy, contains not only nutrients but also an array of bioactive substances including metabolic hormones. Nonetheless, only a few studies have reported concentrations of metabolic hormones in human milk specifically from women with metabolic abnormalities. We aim to investigate the impact of maternal metabolic abnormalities in pregnancy on human milk hormones and subsequently on infant development over the first year of life. The objective of this report is to present the methodology and design of this study. Methods/Design The current investigation is a prospective study conducted within ongoing cohort studies of women and their offspring. Pregnant women attending outpatient obstetrics clinics in Toronto, Canada were recruited. Between April 2009 and July 2010, a total of 216 pregnant women underwent a baseline oral glucose tolerance test and provided medical and lifestyle history. Follow-up visits and telephone interviews are conducted and expected to be completed in October 2011. Upon delivery, infant birth anthropometry measurements and human breast milk samples are collected. At 3 and 12 months postpartum, mothers and infants are invited for follow-up assessments. Interim telephone interviews are conducted during the first year of offspring life to characterize infant feeding and supplementation behaviors. Discussion An improved understanding of the link between maternal metabolic abnormalities in pregnancy and early infant nutrition may

    We hypothesized that a standing flank ovariohysterectomy procedure could be developed in beef heifers that would provide high quality tissues for addressing critical questions during early pregnancy, while concomitantly keeping livestock stewardship a high priority. To test the hypothesis, we: 1) developed a standing flank ovariohysterectomy procedure for use in beef heifers, and 2) implemented this procedure in a cohort of heifers up to d 50 of pregnancy for tissue collections, documentation of post-surgical recovery, and assessment of feedlot finishing performance. Ovariectomy and cesarean section protocols are well established in research and veterinary medicine and were used as starting points for procedural development. Crossbred Angus heifers ( = 46; ∼ 15 mo of age; BW = 362.3 ± 34.7 kg) were used to develop this new surgical tissue collection technique. Heifers were subjected to the 5-d CO-Synch + CIDR estrous synchronization protocol so ovariohysterectomy occurred at d 16, 22, 28, 34, 40, and 50 of gestation. Key aspects of the standing flank ovariohysterectomy technique included 1) use of local anesthetic for a standing flank incision, 2) locate the uterine and ovarian arteries via blind palpation and ligate them through the broad ligament via an improved clinch knot, 3) cut the ovaries and uterus free from the broad ligament, 4) ligate the cervix and uterine branch of the vaginal artery, and 5) cut through the cervix and remove the reproductive tract. Surgical times, from skin incision to placement of the last suture, were influenced ( = 0.04) by stage of gestation. In pregnant heifers, time decreased from d 22 (120.0 ± 12.0 min) of gestation to d 40 (79.5 ± 12.0 min) of gestation; then increased at d 50 (90.5 ± 14.7 min) of gestation. Using this procedure, we obtained uterine, placental, and embryo/fetal tissues that had experienced limited hypoxia, little or no trauma, and thus were excellent quality for scientific study. All heifers recovered

    To explore adolescent health seeking behavior during pregnancy and early motherhood in order to contribute to health policy formulation and improved access to health care. This will in long-term have an impact on the reduction of morbidity and mortality among adolescent mothers and their newborns. This was a qualitative study that employed focus group discussions (FGDs) among adolescent girls (10-19 years) and key informant (KI) interviews with health workers. Age for FGD participants ranged from 16 to 19 years. The FGD participants were recruited while seeking antenatal care for their first pregnancy or immunization service for their first child, not being older than 6 months. Six health facilities were selected. Key informants were purposefully selected on the basis of being in-charge of maternity units. Thirteen FGDs comprising of a total of 92 adolescent girls were conducted. The FGDs were held with homogeneously constituted categories; married pregnant adolescents (5), unmarried pregnant adolescents (3) and married or not married adolescents with children (5). Semi structured interviews were held with six KIs who were in-charge of maternity units of health facilities. Latent content analysis technique was used for data analysis. Two main themes emerged; 'feeling exposed and powerless', and 'seeking safety and empathy'. The categories identified in the first theme were "the dilemma of becoming an adolescent mother" and "lack of decision power". In the second theme the following categories were identified: "cultural practices and beliefs about birth", "expectations and experiences", "transport, a key determinant to health seeking", and "dealing with constraints". Adolescents felt exposed and powerless due to the dilemma of early motherhood and lack of decision making power. The adolescent mothers seemed to be in continuous quest for safety and empathy. In so doing they are part of cultural practices and beliefs about birth. They had expectations about the health

    Full Text Available Abstract Background Bacterial vaginosis (BV is the single most common vaginal infection in women of childbearing age and associated with a sizeable infectious disease burden among both non-pregnant and pregnant women, including a significantly elevated risk of adverse pregnancy outcome. Overall, little progress has been made in identifying causal factors involved in BV acquisition and persistence. We sought to evaluate maternal iron status in early pregnancy as a putative risk factor for BV, considering that micronutrients, and iron deficiency in particular, affect the host response against bacterial colonization, even in the setting of mild micronutrient deficiencies. Methods In a nested case-control study, we compared maternal iron status at entry to prenatal care (mean gestational age 9.2 ± 2.6 weeks between eighty women with healthy vaginal microflora and eighteen women with vaginosis-like microflora. Vaginal microflora status was assessed by assigning a modified Nugent score to a Gram-stained vaginal smear. Maternal iron status was assayed by an array of conventional erythrocyte and serum indicators for iron status assessment, but also by more sensitive and more specific indicators of iron deficiency, including soluble transferrin receptors (sTfR as an accurate measure of cellular and tissue iron deficiency and the iron deficiency log10[sTfR/ferritin] index as the presently most accurate measure of body storage iron available. Results We found no statistically significant correlation between vaginal microflora status and routinely assessed iron parameters. In contrast, a highly significant difference between the healthy and vaginosis-like microflora groups of women was shown in mean values of sTfR concentrations (1.15 ± 0.30 mg/L versus 1.37 ± 0.38 mg/L, p = 0.008 and in mean iron deficiency log10[sTfR/ferritin] index values (1.57 ± 0.30 versus 1.08 ± 0.56, p = 0.003, indicating a strong association between iron deficiency and

    Expression of Smad2 and Smad4 mRNAs in the endometrium of rhesus monkey on Days 8, 20 and 28 of the normal menstrual cycle and on Days 12, 18 and 26 of early pregnancy was detected using in situ hybridization. The results showed that Smad2 and Smad4 mRNAs were mainly localized in luminal epithelium and glandular epithelium. The expression of Smad2 mRNA in glandular epithelium was sustained at moderate level on Days 8, 20 and 28 of the menstrual cycle, while the expression of Smad4 gradually increased with the menstrual cycle. Both Smad2 and Smad4 mRNAs in functionalis glandular epithelium were expressed at the highest levels on Day 12 of early pregnancy, while in basalis glandular epithelium the most abundant expression of both Smads occurred on Days 12 and 18 of pregnancy. On Day 26, both Smads mRNAs were expressed at the lowest levels either in functionalis or in basalis. The data suggest that the epithelium is the major compartment where TGF-βs/activins exert their biological effects via Smads, and that Smad4 may play a role in the maintenance of endometrial gland function during secreting period of the menstrual cycle. During lacunar stage of early pregnancy, Smad2 and Smad4 are implicated in the tissue remodeling of endometrial functionalis and basalis, and during early villous stage both Smads are functional primarily in basalis.

    The aim of this study was to explore changes in health-related quality of life, anxiety and depression symptoms during pregnancy in women with pregestational diabetes. An observational cohort study including 137 pregnant women with pregestational diabetes (110 with type 1 and 27 with type 2). To evaluate changes from early to late pregnancy, the internationally validated questionnaires 36-Item Short-Form Health Survey (SF-36) and Hospital Anxiety and Depression Scale (HADS) were completed at 8 and 33 gestational weeks. From early to late pregnancy, the SF-36 scales Physical Function, Role Physical, Bodily Pain and Physical Component Summary worsened (p anxiety score improved slightly from 5.0 (3.3) to 4.5 (3.4) (p = 0.04) whereas the HADS depression score remained unchanged. The prevalence of women with HADS anxiety or depression score ≥8 did not change. Physical quality of life deteriorated whereas mental quality of life improved slightly during pregnancy in women with pregestational diabetes. A minor reduction in anxiety and stable depression symptoms was observed. The results on mental health are reassuring, considering the great demands that pregnancy places on women with pregestational diabetes. © 2016 Nordic Federation of Societies of Obstetrics and Gynecology.

    William Simpson

    Full Text Available Objective: Perinatal depressive symptoms often co-occur with other inflammatory morbidities of pregnancy. The goals of our study were 1 to examine whether changes in inflammatory markers from the third trimester of pregnancy to 12 weeks postpartum were associated with changes in depressive symptoms; 2 to examine whether third trimester inflammatory markers alone were predictive of postpartum depressive symptoms; and 3 to examine the relationship between inflammatory markers and depressive symptoms during the third trimester of pregnancy and at 12 weeks postpartum. Methods: Thirty-three healthy pregnant women were recruited from the Women’s Health Concerns Clinic at St. Joseph’s Healthcare in Hamilton, Canada. The impact of depressive symptoms on the levels of interleukin (IL-6, IL-10, tumor necrosis factor alpha (TNF-α, and C-reactive protein (CRP at the third trimester of pregnancy, at 12 weeks postpartum, and across time was assessed using linear and mixed-model regression. Results: Regression analysis revealed no significant association between depressive symptoms and any of the candidate biomarkers during pregnancy, at 12 weeks postpartum, or over time. Pregnancy depressive symptoms (p > 0.001, IL-6 (p = 0.025, and IL-10 (p = 0.006 were significant predictors of postpartum Edinburgh Perinatal Depression Scale (EPDS score. Conclusions: Our study supports previous reports from the literature showing no relationship between inflammatory biomarkers and depressive symptoms during late pregnancy, early postpartum, or across time. Our study is the first to observe an association between late pregnancy levels of IL-6 and IL-10 and postpartum depressive symptoms. Further studies with larger samples are required to confirm these findings.

  5. [Changes in the innervation of the uterus during pregnancy and following parturition. Histochemical and electron microscopic observations in rat and humans].

    A histochemical, electronmicroscopic study was made of time changes in uterine nerves during and after pregnancy in rats. Uterine observations in pregnant humans were also conducted with the following results. 1. Except at the oviductal end, the catecholamine (CA) fluorescence of adrenergic nerves distributed in the uterine horn myometrium begins to decrease around the implantation sites, and this spreads peripherally until most of the fluorescence in the uterine horns, including the mesometrium, disappears directly after parturition. 2. In lactating rats, fluorescence is almost completely restored by 1 month after parturition. But in non-lactating rats, recovery of fluorescence after parturition is delayed about 3 months. 3. The activity of acetylcholinesterase (AChE) in rat uterine cholinergic nerves clearly decreased during pregnancy. 4. In the early, middle and late periods of pregnancy, axonal swelling, agglutination of axonal cytoplasm and mitochondrial breakdown were observed, but no marked degeneration appeared in virgin rat uteri. 5. In humans, there was a sporadic distribution of adrenergic nerves in the uterine body myometrium, but fluorescent fibers were present in the terminal period of pregnancy. These results suggest that rat uterine nerves, especially most adrenergic nerves, degenerate and regenerate throughout pregnancy, parturition and puerperium. Apparently a localized humoral factor from the placenta and systemic endocrine environment affected by lactation or non-lactation is involved in the process.

    Reproductive health care, including treatment of early pregnancy failure (EPF) and induced abortion, is an integral part of patient-centered care provided by family physicians, but data suggest that comprehensive training is not widely available to family medicine residents. The purpose of this study was to assess EPF and induced abortion management practices and attitudes of family medicine physician educators throughout the United States and Canada. These data were collected as part of a cross-sectional survey conducted by the Council of Academic Family Medicine Educational Research Alliance that was distributed via E-mail to 3152 practicing physician members of Council of Academic Family Medicine organizations. The vast majority of respondents (88.2%) had treated EPF, whereas few respondents (15.3%) had provided induced medication or aspiration abortions. Of those who had treated EPF, most had offered medication management (72.7%), whereas a minority had provided aspiration management (16.4%). Almost all respondents (95%) agreed that EPF management is within the scope of family medicine, and nearly three-quarters (73.2%) agreed that early induced abortion is within the scope of family medicine. Our findings suggest that family physician educators are more experienced with EPF management than elective abortion. Given the overlap of skills needed for provision of these services, there is the potential to increase the number of family physician faculty members providing induced abortions.

  8. Gene expression in the mouse brain following early pregnancy exposure to ethanol

    Full Text Available Exposure to alcohol during early embryonic or fetal development has been linked with a variety of adverse outcomes, the most common of which are structural and functional abnormalities of the central nervous system [1]. Behavioural and cognitive deficits reported in individuals exposed to alcohol in utero include intellectual impairment, learning and memory difficulties, diminished executive functioning, attention problems, poor motor function and hyperactivity [2]. The economic and social costs of these outcomes are substantial and profound [3,4]. Improvement of neurobehavioural outcomes following prenatal alcohol exposure requires greater understanding of the mechanisms of alcohol-induced damage to the brain. Here we use a mouse model of relatively moderate ethanol exposure early in pregnancy and profile gene expression in the hippocampus and caudate putamen of adult male offspring. The effects of offspring sex and age on ethanol-sensitive hippocampal gene expression were also examined. All array data are available at the Gene Expression Omnibus (GEO repository under accession number GSE87736.

    Objectives To examine the effect of mifepristone compound (mifepristone + anordrin) on estrogen receptor (ER) and progesterone receptor (PR) in early pregnancy decidua.Materials & Methods A Controlled study was carried out among 60 normal early pregnant volunteers ( ≤ 49 d) in the department of obstetric and gynecology of Peking Union Medical Hospital. The concentrations of ER and PR were measured by radioligand and were compared with the control subjects after oral administration of mifepristone or mifepristone compound in different doses.Results The concentration of PR decreased while that of ER increased significantly in the decidua from all subjects administrated with mifepristone compound. We also found the concentration of EcR in Group 5 (mifepristone 30 mg + AF- 53 5 mg) was the highest among 6 groups. The compound may be in favor of estrogen's action on endometrium.Conclusion The results indicate that mi f epristone compound with AF-53 has a coordinated function and can change the proportion of PR and ER. Hence, it can facilitate abortion. The compound dose of mifepristone 30 mg q- AF- 53 5 mg is in favor of the endometrium recovering.

    Areca nut (Areca catechu) is chewed by roughly 10% of the world population, including India, Taiwan and parts of China. Lower mean birth-weight and higher neonatal jaundice were reported in the babies of betel chewing pregnant women in 1982. Although areca nut chewing during pregnancy has been associated with lower birth weight and premature delivery, the mechanism of such complications is not entirely understood. A possible contributor, arecoline, a major alkaloid in the areca nut, has been reported to be cytotoxic and genotoxic. To determine the influence of arecoline on reproduction, we study the effects of arecoline on embryos during peri-implantation stages in mice. Mice consuming varying dosages of arecoline were checked for their ability to successfully produce viable embryos. In addition, trophoblast outgrowth from mice blastocysts was evaluated the survival status of the embryos. Our investigation revealed that arecoline decreased the number of implanted embryos in early pregnant mice. In addition, trophoblast outgrowth expansion of blastocysts was also inhibited by arecoline. These observations suggest that arecoline is toxic to mouse embryos as early as peri-implantation. Improved understanding of the effects of arecoline during embryogenesis may help to establish public health policies and to develop potential treatments for such patients.

    To determine the risk of congenital toxoplasmosis (CT) and provide early (pre- or postnatal) identification of cases of CT in the absence of systematic screening in pregnancy.I n the presented cross-sectional study, serological criteria were used to date Toxoplasma gondii infection versus conception in 80 pregnant women with fetal abnormalities or referred to as suspected of acute infection, and in 16 women after delivery of symptomatic neonates. A combination of serological, molecular (qPCR), and biological (bioassay) methods was used for prenatal and/or postnatal diagnosis of CT. Most (77.5%) pregnant women were examined in advanced pregnancy. Of all the examined seropositive women (n = 90), infection could not be ruled out to have occurred during pregnancy in 93.3%, of which the majority (69%) was dated to the periconceptual period. CT was diagnosed in 25 cases, of which 17 prenatally and 8 postnatally. Molecular diagnosis proved superior, but the diagnosis of CT based on bioassay in 7 instances and by Western blot in 2 neonates shows that other methods remain indispensable. In the absence of systematic screening in pregnancy, maternal infection is often diagnosed late, or even only when fetal/neonatal infection is suspected. In such situations, use of a complex algorithm involving a combination of serological, biological, and molecular methods allows for prenatal and/or early postnatal diagnosis of CT, but lacks the preventive capacity provided by early maternal treatment.

    Vaginal bleeding in the first trimester has wide differential diagnoses, the most common being a normal early intrauterine pregnancy, with other potential causes including spontaneous abortion and ectopic pregnancy. The incidence of ectopic pregnancy is approximately 2% of all reported pregnancies and is one of the leading causes of maternal mortality worldwide. Clinical signs and symptoms of ectopic pregnancy are often nonspecific. History of pelvic pain with bleeding and positive β-human chorionic gonadotropin should raise the possibility of ectopic pregnancy. Knowledge of the different locations of ectopic pregnancy is of utmost importance, in which ultrasound imaging plays a crucial role. This pictorial essay depicts sonographic findings and essential pitfalls in diagnosing ectopic pregnancy.

    All gilts and sows in production from which the detailed production information was available in a 160-sow unit were included to the study. In winter-spring, there were complete data available from 47 animals and in summer-autumn from 64 animals. The farm had a consistent history of the seasonally reduced farrowing rate in summer-autumn. Success of inseminations was monitored during a 4-month breeding period in winter-spring and in summer-autumn. Each animal was bled twice a week for 6 weeks starting a day before insemination and the blood samples were assayed to determine serum progesterone concentration. The blood samples were also assayed for cortisol to detect any acute infectious response. Starting on day 18, animals were pregnancy tested by transcutaneous real time ultrasound twice a week. In winter-spring, the farrowing rate was 72% (58 inseminations, 1.2 inseminations/sow) and in summer-autumn 63% (81 inseminations, 1.3 inseminations/sow). In winter-spring, there was only one detected case of early disruption of pregnancy (EDP), whereas nine such cases were recognised in summer-autumn. Five out of those nine animals returned to oestrus with a mean insemination to oestrus interval of 25.8+/-1.6 days. One sow returned to oestrus 35 days after insemination and three sows did not return to oestrus within 45 days. However, two of these sows had progesterone profiles that indicated an undetected oestrus around day 25. In those nine animals, no acute phase infectious response as indicated by a rise in serum cortisol was evident. Serum progesterone concentrations in the animals eventually loosing the pregnancy tended to be lower on day 13 (no significant difference) and were significantly lower on day 20 when compared with animals remaining pregnant. There was no difference in serum progesterone levels of pregnant animals between winter-spring and summer-autumn. Litter size was not affected by the season. The weaning to oestrus interval tended to be longer in

    The mechanisms of fetal semi-allograft acceptance by the mother's immune system have been the target of many immunological studies. Early pregnancy factor (EPF) is a molecule present in the serum of pregnant mammals soon after conception that has been reported to have immunomodulatory effects. In the present study, we aimed to determine whether immune cells such as CD4(+)CD25(+) regulatory T cells (Tregs) are involved in the suppressive mechanism of EPF. Accordingly, CD4(+)CD25(-) T cells were isolated from spleens of female C57BL/6 mice and stimulated with anti-CD3 antibody, anti-CD28 antibody and IL-2 in the presence or absence of EPF. Flow cytometry was used to analyze the differentiation of CD4(+)CD25(-) T cells to CD4(+)CD25(+) Tregs. We thus found a remarkable rise in the Treg ratio in the EPF-treated cells. Higher mRNA and protein levels of fork head box P3 (Foxp3), a marker of the Treg lineage, were also observed in cells treated with EPF. Furthermore, the effect of EPF on Treg immunosuppressive capacity was evaluated. EPF treatment induced the expression of interleukin-10 and transforming growth factor β1 in Tregs. The suppressive capacity of Tregs was further measured by their capability to inhibit T cell receptor-mediated proliferation of CD4(+)CD25(-) T cells. We thus found that EPF exposure can enhance the immunosuppressive functions of Tregs. Overall, our data suggest that EPF induces the differentiation of Tregs and increases their immunosuppressive activities, which might be an important mechanism to inhibit immune responses during pregnancy.

    Twenty-four healthy female volunteers with amenorrhea for seven weeks or less,asking .for legal termination of pregnancy were recruited and divided into 4 groups (6each), The subjects were orally administered with RU486 of 50mg (Group I), 50mgQ12h×6 (Group Ⅱ ), 200mg (GroupⅢ) or 600mg (Group Ⅳ ). Vacuum aspiration( Group Ⅰ) or Methyl Carprost Suppository ( PG05 1.0mg) (Group Ⅱ-Ⅳ) was given 72h after the first dose followed by a 6-hour medical surveillance. Blood samples were collected on day 1-6, 8, 15, 43 to measure the serum levels of β-hCG, E2, P, PRL,ACTH, Cortisol. T3, T4 and TSH in eaeh subject. The results showed that no significant dose-effect relationship was observed in terms of clinical efficacy, vaginal bleeding or side effects, All four groups shared the same tendency of changes in serum levels of β-hCG, E2 and P, β-hCG levels increased by 50-100% (P 0.05). This study indicated that RU486 has no dose-effect relationship when used for interruption of early pregnancy and its main action site seems neither in ovary nor in villi. It has some effects on pituitary-adrenat axis, especially in large dosage, however, it has no obvious impact on pituitary-thyroid axis. It seems that the changes in PRL serum levels were directly due to the drug itself, its clinical significance should be further studied,

  19. Parent-offspring conflict and the persistence of pregnancy-induced hypertension in modern humans.

    Directory of Open Access Journals (Sweden)

    Birgitte Hollegaard

    Full Text Available Preeclampsia is a major cause of perinatal mortality and disease affecting 5-10% of all pregnancies worldwide, but its etiology remains poorly understood despite considerable research effort. Parent-offspring conflict theory suggests that such hypertensive disorders of pregnancy may have evolved through the ability of fetal genes to increase maternal blood pressure as this enhances general nutrient supply. However, such mechanisms for inducing hypertension in pregnancy would need to incur sufficient offspring health benefits to compensate for the obvious risks for maternal and fetal health towards the end of pregnancy in order to explain why these disorders have not been removed by natural selection in our hunter-gatherer ancestors. We analyzed >750,000 live births in the Danish National Patient Registry and all registered medical diagnoses for up to 30 years after birth. We show that offspring exposed to pregnancy-induced hypertension (PIH in trimester 1 had significantly reduced overall later-life disease risks, but increased risks when PIH exposure started or developed as preeclampsia in later trimesters. Similar patterns were found for first-year mortality. These results suggest that early PIH leading to improved postpartum survival and health represents a balanced compromise between the reproductive interests of parents and offspring, whereas later onset of PIH may reflect an unbalanced parent-offspring conflict at the detriment of maternal and offspring health.

    Full Text Available Abstract Background To explore any association between the timing of the initiation of sexual activity and sexual behaviors and risks among university students in China. Methods Data were derived from a cross-sectional study on sexual behavior among university students conducted in Ningbo municipality, China, at the end of 2003. Students completed a self-administered, structured questionnaire. Of 1981 sexually active male students, 1908 (96.3% completed the item for timing of the initiation of sexual activity and were included in bivariate trend analyses and multiple logistic regression analyses to compare the association between this timing and sexual behavior and risks. Results Male early sexual initiators had a significantly higher risk profile, including a significantly higher proportion reporting non-regular partners (i.e., casual or commercial partners, multiple partners, diagnosis with a sexually transmitted disease (STD, partner history of pregnancy, partner history of induced abortion, and less condom and oral contraceptive use, compared with late initiators. Multivariate analyses confirmed the increased likelihood of these risks in early initiators versus late initiators, other than partner type during the last year. Conclusion Our results showed that, compared to late initiators, people who initiated sexual activity early engaged in more risky behaviors that could lead to elevated risks of unwanted pregnancies and STDs or human immunodeficiency virus infection. Sex-education strategies should be focused on an earlier age, should include advice on delaying the age of first sexual activity, and should target young people who continue to take sexual risks.

    Full Text Available In this data, non-pregnant women during the menstrual cycle, women with normal intrauterine pregnancy (IUP, and women with tubal ectopic pregnancy (EP after informed consent were included. The serum levels of 17β-estradiol, progesterone, testosterone, beta-human chorionic gonadotropin, interleukin (IL-1β, IL-4, IL-6, IL-7, IL-8, IL-10, tumor necrosis factor α (TNFα, and interferon-γ (IFN-γ, epidermal growth factor, the Chlamydia (C. trachomatis IgG and HSP60 were analyzed. Receiver operating characteristic analysis was used to assess the diagnostic discrimination of tubal EP and gestational age-matched IUP. Our data show that C. trachomatis infection is associated with IL-8 levels, which had excellent discriminative validity in positively identifying tubal EP (concomitant with C. trachomatis infection from IUP and non-pregnant conditions regardless of C. trachomatis infection.

    Globally, fifteen million babies are born preterm each year, affecting 1 in 8 pregnancies in the US alone. Cervical remodeling includes a biochemical cascade of changes that ultimately result in the thinning and dilation of the cervix for passage of a fetus. This process is poorly understood and is the focus of this study. Our group is utilizing Raman spectroscopy to evaluate biochemical changes occurring in the human cervix throughout pregnancy. This technique has high molecular specificity and can be performed in vivo, with the potential to unveil new molecular dynamics essential for cervical remodeling.

  3. Human placental development is impaired by abnormal human chorionic gonadotropin signaling in trisomy 21 pregnancies.

    Placental development is markedly abnormal in women bearing a fetus with trisomy 21, with defective syncytiotrophoblast (ST) formation and function. The ST occurs from cytotrophoblast (CT) fusion and plays an essential role by secreting human chorionic gonadotropin (hCG), which is essential to placental development. In trisomy of chromosome 21 (T21) pregnancies, CTs do not fuse and differentiate properly into STs, leading to the secretion of an abnormal and weakly bioactive hCG. In this study we report for the first time, a marked decrease in the number of mature hCG receptor (LH/CG-R) molecules expressed at the surface of T21-affected CTs. The LH/CG-R seems to be functional based on sequencing that revealed no mutations or deletions and binding of recombinant hCG as well as endogenous hCG. We hypothesize that weakly bioactive hCG and lower LH/CG-R expression may be involved in the defect of ST formation. Interestingly, the defective ST formation is mimicked in normal CT cultures by using LH/CG-R small interfering RNA, which result in a lower hCG secretion. Furthermore, treatment of T21-affected CTs with recombinant hCG overcomes in vitro the T21 phenotype, allowing CTs to fuse and form a large ST. These results illustrate for the first time in trisomy 21 pathology, how abnormal endogenous hCG signaling impairs human placental development.

  4. Compartmentalized localization of 11β-HSD 1 and 2 at the feto-maternal interface in the first trimester of human pregnancy.

    Glucocorticoids are engaged in a number of actions at the feto-maternal interface for the establishment of early pregnancy. However, excessive glucocorticoids can be deleterious to fetal development. Therefore, compartmentalized distribution of 11β-hydroxysteroid dehydrogenase 1 and 2 (11β-HSD1 and 2), which regenerates and inactivates cortisol respectively, would ensure an optimal cortisol concentration at the feto-maternal interface for the establishment of early gestation. However, the distribution pattern of 11β-HSD1 and 2 at the feto-maternal interface in early human pregnancy is not clearly defined. Here we showed that 11β-HSD1 distributed extensively on the maternal side including decidual stromal cells and epithelial cells but scarcely on the fetal side except for localization in the fetal blood vessels of the chorionic villi. In contrast, 11β-HSD2 was abundantly localized in syncytial layer of the chorionic villi and the decidual epithelium. In primary cultures, cortisol upregulated not only 11β-HSD1 expression in decidual stromal cells but also 11β-HSD2 expression in villous trophoblasts of early pregnancy. Further studies revealed that cortisol inhibited the expression of interleukin-1β and 6 in decidual stromal cells and villous trophoblasts, and stimulated expression of human chorionic gonadotropin in villous trophoblasts. Collectively, this study has revealed a compartmentalized distribution pattern of 11β-HSD 1 and 2 at the feto-maternal interface, both of which can be upregulated by glucocorticoids, suggesting that a coordinated interaction between 11β-HSD 1 and 2 may exist to ensure an optimal cortisol concentration at discrete locations at the feto-maternal interface for the establishment of early pregnancy.

    In this study, we investigated whether the concentrations of pregnancy-associated plasma protein-A (PAPP-A) or free β-hCG (fβhCG) in the first trimester can identify women at increased risk of subsequent preterm delivery in the absence of hypertensive disorders. Preterm and early preterm deliveries are defined as those deliveries before completing 37 and 34 weeks, respectively. A total of 868 women were enrolled into this study. According to the level of the markers, the patients were evaluated in three groups: 1 - maternal serum level ≤ 5 th percentile, 2 - between 5th and 95th percentiles, 3 - ≥ 95 th percentile. In the group of patients with a PAPP-A level ≤ 5 th percentile [≤ 0.35 multiples of the median (MoM)], mean gestational age (GA) at delivery, mean birth weight and the number of the cases with early preterm delivery were significantly lower than the others. Mean level of PAPP-A was significantly lower in cases with early preterm than term deliveries (0.58 ± 0.32 versus 1.09 ± 0.69; p = 0.01). Maternal serum level of fβhCG did not show significant difference between these groups (0.84 ± 0.45 versus 1.17 ± 0.77; p = 0.15). Low levels of maternal serum PAPP-A (≤ 0.35 MoM) (Odds ratio = 7; 95% confidence interval 1.8-27.7; p = 0.0048) significantly predicted early preterm delivery in normotensive pregnancies. Women with low levels of PAPP-A at first trimester have a higher risk of early preterm delivery even in the absence of hypertensive disorders.

    Deciduallzation is accompanied by extensive angiogenesis, which is an essential step In the maturation of new blood vessels in mammalian pregnancy. The purpose of this study was to determine a distribution of uNK cells (CD56+ uNK or CD56brlght cells) in human decidua of the first-trimestsr pregnancy, and investigate whether uNK cells in human decidua could express vascular endothelial growth factor (VEGF-A) and/or angiopoietin2 (Ang2), Our immunohistochemical staining results demonstrated that a great amount of uNK (CD56+) cells scattered throughout the decidual stroma and near endometriel gland and spiral vessels in human decidua. The protein expression of VEGF-A and Ang2 was detected in decidual stroma cells, capillary endothelial cells and glandular cells in tissue specimens. There was a positive correlation between microvessel density (MVD) and the number of the CD56-positive uNK cells in decldual stroma, and also between the number of the CD56-positive UNK cells and VEGF-A protein expression in the tissue. In addition, we found that uNK cells in human decidua could express YEGF-A mRNA, but not Ang2 mRNA, in Isolated uNK cells in human decidua of the first-trimester gestation by combination of LCM and Nested-PCR. Our study Indicated that uNK cells, through expressing VEGF-A, may play an important role in the angiogenic response at the time of human decidualization and early placenta development.

    Increased human chorionic gonadotropin levels (HCG) can be detected in femoral blood, bile, and vitreous humor collected during autopsy of pregnant women using a standard kit designed for living patients. In the study herein, the concentrations of HCG were measured in postmortem serum, vitreous, bile, cerebrospinal, and pericardial fluids in 4 cases of fatal ectopic pregnancy and 40 controls using a quantitative electrochemiluminescence immunoassay designed for living patients. No false-negative cases were identified in any of the analyzed samples in any of the ectopic pregnancy cases. No correlations were found between total HCG levels in postmortem serum and the other tested specimens. The results of this study would suggest that higher HCG in bile, vitreous, pericardial, and cerebrospinal fluids may confirm the existence of ectopic pregnancy and therefore identify other situations in which this hormone is increased, although gestational age cannot be reliably estimated using these values. © 2015 American Academy of Forensic Sciences.

    Mouse and vole embryos were allogeneically and xenogeneically transferred into pseudopregnant CD.1 and immunodeficient (seid)female mice,and we investigated the distribution of uterine leucocytes cells in the implantation sites on days 5,6,and 7 of pregnancy. Maerophages were evenly distributed in the endometrium on days 5-7.Neutrophils were rarely seen on days 5-7,but lymphocytes were found throughout the endometrium,often in groups associated with glands or the luminal epithelium.The number of uNK cells increased markedly at the mesometrial uriangle and the outer decidual area in the CD-1 uteri containing vole embryos;by contrast,seid uteri having vole embryos showed almost the same number as those having mouse embryos.Mast cells were present in large numbers at the myometrium,but rarely in the decidua in all types of pregnant uteri.Cells at the myometrium were more numerous in xenogeneic than in allogeneic transfer.Maay mast cells appeared in the inner decidua where xenogeneically transferred vole embryos were dead and aborted.These results suggest the possibility that uterine leucocytes mediate various immunological events in the mouse-vole interspesific pregnancies.

    To assess and compare the ability of serum β-human chorionic gonadotropin (β-hCG) and serum lipid profile in early second trimester as predictors of hypertensive disorders of pregnancy. The present hospital-based prospective study was conducted between November 24, 2012, and April 30, 2014, at a tertiary hospital in Mangalore, India. Women of any parity with a pregnancy of 14-20 weeks were included. Venous blood (3 mL) was collected, and serum β-hCG and lipid profile were estimated by enzyme-linked immunosorbent assay and an enzymatic colorimetric test with lipid clearing factor, respectively. A cutoff value of β-hCG for predicting hypertensive disorders was obtained by receiver operating curve analysis. Serum β-hCG was significantly higher among women who subsequently developed hypertension (71 142 IU/L [n=27]) than among those who did not (20 541 IU/L [n=137]; PhCG to predict hypertension were 92.6% and 94.9% respectively. The positive and negative predictive values were 78.1% and 98.5%, respectively. Serum β-hCG might be used as a predictor of hypertensive disorders that complicate pregnancy. Dyslipidemia was not found to be a useful marker. © 2017 International Federation of Gynecology and Obstetrics.

    Full Text Available Abstract Background Increasing access to safe abortion services is the most effective way of preventing the burden of unsafe abortion, which is achieved by increasing safe choices for pregnancy termination. Medical abortion for termination of early abortion is said to safe, effective, and acceptable to women in several countries. In Ethiopia, however, medical methods have, until recently, never been used. For this reason it is important to assess women's preferences and the acceptability of medical abortion and manual vacuum aspiration (MVA in the early first trimester pregnancy termination and factors affecting acceptability of medical and MVA abortion services. Methods A prospective study was conducted in two hospitals and two clinics from March 2009 to November 2009. The study population consisted of 414 subjects over the age of 18 with intrauterine pregnancies of up to 63 days' estimated gestation. Of these 251 subjects received mifepristone and misoprostol and 159 subjects received MVA. Questionnaires regarding expectations and experiences were administered before the abortion and at the 2-week follow-up visit. Results The study groups were similar with respect to age, marital status, educational status, religion and ethnicity. Their mean age was about 23, majority in both group completed secondary education and about half were married. Place of residence and duration of pregnancy were associated with method choice. Subjects undergoing medical abortions reported significantly greater satisfaction than those undergoing surgical abortions (91.2% vs 82.4%; P Conclusions Women receiving medical abortion were more satisfied with their method and more likely to choose the same method again than were subjects undergoing surgical abortion. We conclude that medical abortion can be used widely as an alternative method for early pregnancy termination.

    The researchers' aim was to examine whether it was better to predict new-onset postpartum depression (PPD) during pregnancy or immediately after childbirth. A prospective study conducted in Croatia followed women (N = 272) from the third trimester of pregnancy through the early postpartum period (within the first 3 postpartum days), to 6 weeks postpartum. Questionnaires on depression, anxiety, stress, coping, self-esteem, and social support were administered. Through regression analyses we showed that PPD symptoms could be equally predicted by variables from pregnancy (30.3%) and the early postpartum period (34.0%), with a small advantage of PPD prediction in the early postpartum period.

    Full Text Available Introduction: Prenatal diagnosis is testing for detection of diseases or conditions in a fetus or embryo before it is born. Most of prenatal diagnostic (PD techniques are invasive and done in late stages of pregnancy. Using fetal DNA in maternal blood for fetal sex determination in early pregnancy might help in management of X-linked genetic diseases. This study aimed to investigate the accuracy of sex determination using fetal DNA in maternal blood at 8-12 weeks of gestation. Methods: In this cross-sectional study, 30 pregnant women at 8-12 weeks of gestation were enrolled. The sex-determining region Y (SRY gene expression with the internal control (IC glyceraldehyde 3-phosphate dehydrogenase (GAPDH was investigated with quantitative real-time polymerase chain reaction (PCR using specific primers and probes. Results: Accuracy of sex determination with SRY gene expression in 8-12 weeks of pregnancy were 85%, 85%, 90% and 100% respectively. Conclusion: It seems that fetal sex determining using fetal DNA in maternal blood is a reliable method for early stage of pregnancy.

    Tularemia is a zoonotic infection caused by Francisella tularensis with a worldwide distribution and diverse clinical manifestations. Although F. tularensis has been recognized as a human pathogen for a century, there are few reports regarding the occurrence of tularemia in pregnant women and its effect on the fetus; only seven cases have been reported in the literature. In view of the sparse literature, it is not clear whether tularemia increases the risk of adverse pregnancy outcomes. In this paper we review tularemia infection during pregnancy, its complications and management. In addition, we present a case of tularemia that occurred in the first trimester of pregnancy and resulted in third-trimester intrauterine fetal death, highlighting the consequences of tularemia in pregnancy and the importance of early detection and treatment.

    Full Text Available We have previously shown that in successful pregnancies increased arginase activity is a mechanism that contributes to the suppression of the maternal immune system. We identified the main type of arginase-expressing cells as a population of activated low-density granulocytes (LDGs in peripheral blood mononuclear cells and in term placentae. In the present study, we analyzed the phenotype of LDGs and compared it to the phenotype of normal density granulocytes (NDGs in maternal peripheral blood, placental biopsies and cord blood. Our data reveal that only LDGs but no NDGs could be detected in placental biopsies. Phenotypically, NDGs and LDGs from both maternal and cord blood expressed different levels of maturation, activation and degranulation markers. NDGs from the maternal and cord blood were phenotypically similar, while maternal, cord and placental LDGs showed different expression levels of CD66b. LDGs present in cord blood expressed higher levels of arginase compared to maternal and placental LDGs. In summary, our results show that in maternal and cord blood, two phenotypically different populations of neutrophils can be identified, whereas in term placentae, only activated neutrophils are present.

    2015-01-01

    Epidemiological studies have led scientists to postulate the developmental origins of health and disease hypothesis for noncommunicable diseases such as diabetes, cardiovascular diseases, hypertension, and obesity. However, the cellular and molecular mechanisms involved in the development of these diseases are not well understood. In various animal models, it has been observed that oxidative stress during pregnancy is associated with the early development of endothelial dysfunction in offspring. This phenomenon suggests that endothelial dysfunction may initiate in the uterus and could lead to increased risk of cardiovascular disease later in life. Currently, it is known that many of the fetal adaptive responses to environmental factors are mediated by epigenetic changes in the genome, especially by the degree of methylation in cytosines in the promoter regions of genes. These findings suggest that the establishment of a particular epigenetic pattern in the genome may be generated by oxidative stress. © The Author(s) 2014.

    2009-08-01

    Full Text Available Abstract Background The evidence of an association between neighbourhood deprivation and overweight is established for different populations. However no previous studies on neighbourhood variations in obesity in pregnant women were found. In this study we aimed to determine whether obesity during early pregnancy varied by neighbourhood economic status. Methods A register based study on 94,323 primiparous pregnant women in 586 Swedish neighbourhoods during the years 1992–2001. Multilevel technique was used to regress obesity prevalence on socioeconomic individual-level variables and the neighbourhood economic status. Five hundred and eighty-six neighbourhoods in the three major cities of Sweden, Stockholm, Göteborg and Malmö, during 1992–2001, were included. The majority of neighbourhoods had a population of 4 000–10 000 inhabitants. Results Seven per cent of the variation in obesity prevalence was at the neighbourhood level and the odds of being obese were almost doubled in poor areas. Conclusion Our findings supports a community approach in the prevention of obesity in general and thus also in pregnant women.

    Full Text Available BACKGROUND Maternal overweight/obesity causes many complications during pregnancy and delivery. It can also increase neonatal and infant morbidity and mortality. BMI is an important measure of under/overweight. This observational study examines the correlation between maternal Body Mass Index (BMI with maternal outcome in women. MATERIALS AND METHODS This study was conducted at Department of Obstetrics and Gynaecology, Government Medical College, Kottayam, Kerala, for a period of one year. A sample of 300 pregnant women with intrauterine pregnancy of gestational age <12 weeks at first visit was taken for this study with an age between 18 and 35 years with singleton pregnancy. BMI of these women were calculated and they were classified into two categories (BMI <23 kg/m2 and BMI ≥23 kg/m2 . The Chi-square test was done to find the association of BMI and various maternal outcomes. RESULTS In the sample of 300 pregnant women, 39% were having BMI <23 kg/m2 and 61% were having BMI ≥23 kg/m2 . Pregnant women with BMI ≥23 kg/m2 were found to have significantly increased risk of developing gestational hypertension, gestational diabetes and macrosomia. We found that a significantly increased need of induction and increased risk of developing intrapartum and postpartum complications in those with BMI ≥23 kg/m2 . Our study also found out that an increased incidence of elective as well as emergency caesareans and increased risk of neonatal complications in women whose BMI ≥23 kg/m2 . CONCLUSION Adverse maternal and perinatal outcomes are significantly related to extremes of BMI categories and least complications were seen in normal BMI group. Therefore, it is ideal to reduce the body weight to an optimal level so that the complications, which are attributed to overweight and obesity can be reduced. We recommended future research on the association of BMI and maternal outcomes involving large samples comparable to those done in developed countries.

    Regulatory T cells (Tregs) support pregnancy maintenance by suppressing placental inflammation, while diminished Treg function may accompany reproductive failure. Experimental FIV infection frequently results in vertical transmission and increased pregnancy failure in the cat. The mechanism of reproductive compromise is unknown. We hypothesized that FIV infection alters endometrial Treg population dynamics and function, potentiating vertical transmission and reproductive failure. RNA collected from early and late gestation reproductive tissue and fetuses from FIV infected and control cats was probed for expression of FIV gag and Treg markers CD25, FOXP3, and CTLA4, using real time reverse-transcriptase (RT)-PCR. Frequent placental and fetal infection and reproductive failure were detected at early and late pregnancy. Expression of FOXP3 and CTLA4 was higher in early gestation tissues from control cats. FIV infection significantly reduced expression of FOXP3 and CTLA4 at early, but not late pregnancy. At late pregnancy, CTLA4 was expressed to higher levels in infected tissues. The number of tissues with decreased co-expression of FOXP3 and CTLA4 was significant in infected cats at early pregnancy. No significant changes in CD25 expression occurred between FIV-infected and control animals at early or late pregnancy. Differences in Treg marker expression were not significant between viable and non-viable pregnancies in infected cats. The detection of Treg markers in these feline tissues provides the first evidence of feline endometrial Tregs and suggests that such cells diminish as pregnancy progresses. These cells may be depleted or rendered less functional by viral infection, but understanding their role in pregnancy requires further study.

    2014-09-01

    New early first-trimester diagnostic criteria for nonviable pregnancy recommended by the Society of Radiologists in Ultrasound via a multispecialty consensus panel extended the diagnostic size criteria of crown-rump length from 5 to 7 mm for embryos without a heartbeat and mean sac diameter from 16 to 25 mm for "empty" sacs. Our study assessed the potential impact of the new criteria on the number of additional follow-up sonograms these changes would engender. A retrospective study of all first-trimester sonograms in women with first trimester bleeding from 1999 to 2008 was conducted. Everyone included in the study had a visible gestational sac in the uterus. There were no pregnancies of unknown location or ectopic pregnancies included in this study cohort. Pregnancy of unknown location was used to describe cases in which there were no signs of pregnancy inside or outside the uterus on transvaginal sonography despite a positive pregnancy test result. A total of 1013 patients met the inclusion criteria. Seven hundred fifty-two patients (74%) had identifiable embryos, and 261 (26%) did not. Of those with an identifiable embryo, 286 (38%) had no detectable embryonic cardiac activity. The breakdown of crown-rump lengths in this group was as follows: 100 measuring less than 5 mm, 36 measuring 5 to 7 mm, and 150 measuring 7 mm or greater. The breakdown of mean sac diameters in those without a visible embryo was as follows: 120 measuring less than 16 mm, 90 measuring 16 to 25 mm, and 51 measuring 25 mm or greater. When diagnosing a failed pregnancy, there can be no room for error. Only 126 of 1013 early pregnancies threatening to abort (12%) fell into the more conservative zones defined by the new compared to the former size criteria (crown-rump length, 5-7 mm; mean sac diameter, 16-25 mm). Therefore, the potential impact of the new guidelines on follow-up sonograms does not appear inordinate. © 2014 by the American Institute of Ultrasound in Medicine.

    OBJECTIVE(S): Early pregnancy failure (EPF) is a common complication of pregnancy. Surgical intervention carries a risk of complications and, therefore, medical treatment appears to be a safe alternative. Unfortunately, the current medical treatment with misoprostol alone has complete evacuation rat

    Pregnancy is accompanied by prolonged exposure to high estrogen levels. Animal studies have shown that estrogen influences navigation strategies and, hence, affects navigation performance. High estrogen levels are related to increased use of hippocampal-based allocentric strategies and decreased use of striatal-based egocentric strategies. In humans, associations between hormonal shifts and navigation strategies are less well studied. This study compared 30 peripartal women (mean age 28years) to an age-matched control group on allocentric versus egocentric navigation performance (measured in the last month of pregnancy) and gray matter volume (measured within two months after delivery). None of the women had a previous pregnancy before study participation. Relative to controls, pregnant women performed less well in the egocentric condition of the navigation task, but not the allocentric condition. A whole-brain group comparison revealed smaller left striatal volume (putamen) in the peripartal women. Across the two groups, left striatal volume was associated with superior egocentric over allocentric performance. Limited by the cross-sectional study design, the findings are a first indication that human pregnancy might be accompanied by structural brain changes in navigation-related neural systems and concomitant changes in navigation strategy.

    To characterize the hourly profiles of hCG secretion in blood during conceptive cycles that ended in successful pregnancy. Prospective study. University fertility clinic and research laboratories. Healthy spontaneously ovulating women with regular menses, no history of infertility, and either no male partner or an azospermic partner. Frequent blood samples were collected daily from 11 spontaneously ovulating women during 11 cycles of artifical insemination with donor semen. The concentrations of hCG, LH, and FSH were measured in the blood by immunoassay. The concentration of hCG in the frequent blood samples and the rate that the concentration of hCG changed during the period of frequent sampling. For the conceptive cycles resulting in successful pregnancies analyzed, hourly hCG concentrations were observed to increase in a consistent nonpulsatile manner. These data provide the first characterization of the hourly secretion profile of hCG in early pregnancy as well as provide further evidence that individual daily blood samples are sufficient for the accurate assessment of pregnancy.

    This study evaluated the effectiveness and acute toxicity of DL111-IT combined with mifepristone (RU486) and misoprostol (MISO) on early pregnancy termination. In the pregnant rats experiments, the ED(50) values of RU486 in two-drug combinations were 0.16 (combined with DL111-IT) and 0.40 (combined with MISO) mg x kg(-1) x d(-1), while in three-drug combination treatment group (DL111-IT 9.0 mg x kg(-1) (toxicity, the LD(50) values and 95% confidence limit of DL111-IT (i.p.) alone and in combination with RU486 and MISO were 1379.4 (1278.2-1514.7) mg x kg(-1) and 1574.1 (1407.8-1762.7) mg x kg(-1), respectively. There was no significant difference. All data suggested that DL111-IT in combination with RU486 and MISO significantly increased the effect on early pregnancy termination without increasing acute toxicity compared to the treatment of DL111-IT alone, and this combination may be a promising regimen for early pregnancy termination.

    Successful outcome in pregnancy hyperthyroidism depends on the cause, interpretation of laboratory tests, and careful use of antithyroid drug (ATD) therapy. Planning of a pregnancy in a woman with active or past history of Graves' hyperthyroidism is mandatory in order to avoid complications. Fetal health may be affected by three factors: poor control of maternal hyperthyroidism, titer of maternal TRAb, and inappropriate use of ATD. Careful assessment of thyroid function through pregnancy and evaluation of fetal development by ultrasonography is the cornerstone for a successful outcome. In a subgroup of women previously treated with ablation therapy, those whose serum TSRAb titers remained elevated, are at risk of having a fetus/neonate with Graves' hyperthyroidism. Use of ATD during lactation is well tolerated, if recommended guidelines are followed. Women during their childbearing age with active Graves' hyperthyroidism should plan their pregnancy. Causes of hyperthyroidism in pregnancy include Graves' disease or autonomous adenoma, and transient gestational thyrotoxicosis as a consequence of excessive production of human chroionic gonadotropin by the placenta. Careful interpretation of thyroid function tests and frequent adjustment of ATD is of utmost importance in the outcome of pregnancy. Graves' hyperthyroidism may relapse early in pregnancy or at the end of the first year postpartum.

    Clomiphene citrate (2 mg/kg body wt) given on the day of mating can block or interrupt pregnancy in guinea-pigs. Corpus luteum function, uterine histology, implantation and embryo development were studied in clomiphene-treated and control animals on Days 5, 9 and 20 of pregnancy. Following treatment, only 25% of the females were regularly pregnant, presenting large and healthy foetuses. The other females examined showed either pregnancy with embryos undergoing resorption or no sign of pregnancy. In these females, corpus luteum size was reduced, progesterone concentrations were very low and the endometrial glands and the epithelium were often altered. It is concluded that clomiphene causes a reduction in fertility by altering the uterus and, by directly or indirectly inducing luteolysis, causes later pregnancy loss.

    Full Text Available The measurment of various cytokines may provide a different tool for evaluation of the immune system. Recent investigations have shown that the number and function of peripheral natural killer cells (NK- cells increase during early pregnancy in women with a history of unexplained recurrent spontaneous abortions (RSA. NK-cells activity may be responsible for some cases of RSA. The objective of this study was to assess the role of the Thl cytokines (IL-2, IFN-y, TNF-a ; TNF-/0 in this phenomenon, and detection of Thl cytokines in women with RSA. The control group consisted of 40 women with no history of pregnancy loss and complication. The abortion group comprised of 92 women having at least 3 pregnancy losses. Blood from the control group and women with RSA was taken at the end of first trimester of gestational age and at the time of abortion, respectively. Sera were separated and peripheral blood lymphocytes were challenged with PHA using RPMI medium. All samples were tested for concentration of Thl cytokines using ELISA methods. It was considered that sera from women with RSA produced higher concentration of TNF-«, TNF-/? , and IL-2 in comparison with sera from normal pregnant women (NPW (P<0.001. We were not able to detect IL-2 in (NPW whereas in 31% sera from RSA group, IL-2 was detectable (P<0.001. However, there was no significant difference between IFN-y, concentration in sera from patients and control group (P<0.182. Tissue culture supernatant from women with RSA also produced higher concentration of TNF-a. IFN-y, TNF-/* and IL2, than control group. These data may explain the increase NK-cells cytotoxicity during early pregnancy in women with a history of RSA. It may also provide a diagnostic tool to predict the outcome of pregnancy.

    Although {sup 18}F-FDG examinations are widely used, data are lacking on the dose to human embryo tissues in cases of exposure in early pregnancy. Although the photon component can easily be estimated from available data on the pharmacokinetics of {sup 18}F-FDG in female organs and from phantom measurements (considering the uterus as the target organ), the intensity of embryo tissue uptake, which is essential for deriving the {beta}+ dose, is not known. We report the case of a patient who underwent {sup 18}F-FDG PET/CT for tumor surveillance and who was later found to have been pregnant at the time of the examination(embryo age, 8 wk). Methods: The patient received 320 MBq of {sup 18}F-FDG. Imaging started with an unenhanced CT scan 1 h after the injection, followed by PET acquisition. PET images were used to compute the total number of {beta}+ emissions in embryo tissues per unit of injected activity, from standardized uptake value (SUV) measurements corrected for partial-volume effects. A Monte Carlo track structure code was then used to derive the {beta}+ self-dose and the {beta}+ cross-dose from amniotic fluid. The photon and CT doses were added to obtain the final dose received by the embryo. Results: The mean SUV in embryo tissues was 2.7, after correction for the partial-volume effect. The mean corrected SUV of amniotic fluid was 1.1. Monte Carlo simulation showed that the {beta}+ dose to the embryo (self-dose plus cross-dose from amniotic fluid) was 1.8 E-2 mGy per MBq of injected {sup 18}F-FDG. Based on MIRD data for the photon dose to the uterus, the estimated photon dose to the embryo was 1.5 E-2 mGy/MBq. Thus, the specific {sup 18}F-FDG dose to the embryo was 3.3 E-2 mGy/MBq (10.6 mGy in this patient). The CT scan added a further 8.3 mGy. Conclusion: The dose to the embryo is 3.3 E-2 mGy/MBq of {sup 18}F-FDG. The {beta}+ dose contributes 55% of the total dose. This value is higher than previous estimates in late nonhuman-primate pregnancies. (authors)

  13. Global gene expression profiling of individual human oocytes and embryos demonstrates heterogeneity in early development.

    Directory of Open Access Journals (Sweden)

    Lisa Shaw

    Full Text Available Early development in humans is characterised by low and variable embryonic viability, reflected in low fecundity and high rates of miscarriage, relative to other mammals. Data from assisted reproduction programmes provides additional evidence that this is largely mediated at the level of embryonic competence and is highly heterogeneous among embryos. Understanding the basis of this heterogeneity has important implications in a number of areas including: the regulation of early human development, disorders of pregnancy, assisted reproduction programmes, the long term health of children which may be programmed in early development, and the molecular basis of pluripotency in human stem cell populations. We have therefore investigated global gene expression profiles using polyAPCR amplification and microarray technology applied to individual human oocytes and 4-cell and blastocyst stage embryos. In order to explore the basis of any variability in detail, each developmental stage is replicated in triplicate. Our data show that although transcript profiles are highly stage-specific, within each stage they are relatively variable. We describe expression of a number of gene families and pathways including apoptosis, cell cycle and amino acid metabolism, which are variably expressed and may be reflective of embryonic developmental competence. Overall, our data suggest that heterogeneity in human embryo developmental competence is reflected in global transcript profiles, and that the vast majority of existing human embryo gene expression data based on pooled oocytes and embryos need to be reinterpreted.

    2013-01-01

    Full Text Available Aims: Pregnancies achieved by in vitro fertilization (IVF are at increased risk of adverse outcome. The main objective of this study was to evaluate the predictive value of β-human chorionic gonadotrophin (β-HCG and age of the patient for the successful outcome in IVF. Materials and Methods: A retrospective study was done in 139 pregnancies after IVF at single IVF center from June 2007 to July 2012. The age of the patient and initial serum values of β-HCG on day 14 of embryo transfer were correlated with ongoing pregnancy (>12 weeks gestation. Results: The β-HCG level on day 14 of more than 347 mIU/ml has a sensitivity of 72.2% and specificity of 73.6% in prediction of pregnancy beyond 12 weeks period of gestation. Positive likelihood ratio (LR is 2.74 and negative LR is 0.37, (receiver operating characteristic area = 0.79. Discussion: In IVF cycles, there is a lot of stress on the couples while the cycle is going on. There was a positive correlation between the higher values of early serum β-HCG levels and ongoing pregnancy. Hence, it can be used as an independent predictor of a successful outcome of IVF cycle. Conclusion: We concluded from our study that early serum β-HCG can be used as a predictor of a successful outcome in IVF.

  17. Effects of prenatal stress on pregnancy and human development: mechanisms and pathways

    Science.gov (United States)

    Coussons-Read, Mary E

    2013-01-01

    A growing body of research shows that prenatal stress can have significant effects on pregnancy, maternal health and human development across the lifespan. These effects may occur directly through the influence of prenatal stress-related physiological changes on the developing fetus, or indirectly through the effects of prenatal stress on maternal health and pregnancy outcome which, in turn, affect infant health and development. Animal and human studies suggest that activation of the maternal stress response and resulting changes in endocrine and inflammatory activity play a role in the aetiology of these effects. Ongoing research is focusing on clarifying these mechanisms, understanding the role of racial and cultural factors in these effects, and examining the epigenetic and transgenerational influences of prenatal stress.

    This retrospective cohort study reviewed the diagnosis of all ectopic pregnancies within a district general hospital over a 5-year period after the establishment of a dedicated Early Pregnancy Assessment Unit (EPAU). Of 215 ectopic pregnancies identified, notes were available for 208 (97%). Two-hundred and two cases were determined to have been diagnosed and managed as ectopic pregnancies. Six cases were excluded as they were pregnancies of unknown location managed as such. Overall, 91% were diagnosed by ultrasound scan, 5% were diagnosed clinically and 3% were diagnosed on serial human chorionic gonadotrophin (hCG) levels. This study found that the introduction of a dedicated, multi-professional, EPAU with a stable workforce improved ultrasound visualisation of ectopic pregnancies at first ultrasound scan from 22% prior to its commencement, to 61% over this period. The improvement in positive scan diagnosis of ectopic pregnancy was associated with a reduction in negative laparoscopy rate from 13% to 6%.

    No previous study has shown the validity of a food frequency questionnaire (FFQ) in early pregnancy with consideration of nausea and vomiting during pregnancy (NVP). The aim of this study was to evaluate the validity of a FFQ in early pregnancy for Japanese pregnant women. We included 188 women before 15 weeks of gestation and compared estimated nutrient intake and food group intake based on a modified FFQ with that based on 3-day dietary records (DRs). Spearman's rank correlation coefficients, adjusting energy intake and attenuating within-person error, were calculated. Subgroup analysis for those with and without NVP was conducted. We also examined the degree of appropriate classification across categories between FFQ and DRs through division of consumption of nutrients and food groups into quintiles. Crude Spearman's correlation coefficients of nutrients ranged from 0.098 (sodium) to 0.401 (vitamin C), and all of the 36 nutrients were statistically significant. In 27 food groups, correlation coefficients ranged from -0.015 (alcohol) to 0.572 (yogurt), and 81% were statistically significant. In subgroup analysis, correlation coefficients in 89% of nutrients and 70% of food groups in women with NVP and 97% of nutrients and 74% of food groups in women without NVP were statistically significant. On average, 63.7% of nutrients and 60.4% of food groups were classified into same or adjacent quintiles according to the FFQ and DRs. The FFQ is a useful instrument, regardless of NVP, for assessing the diet of women in early pregnancy in Japan. Copyright © 2016 The Authors. Production and hosting by Elsevier B.V.

    HIV-related stigma is associated with many psychological challenges; however, minimal research has explored how perceived HIV-related stigma intersects with psychosocial issues that mothers living with HIV may experience including depression, perceived stress and social isolation. The present study aims to describe the correlates and predictors of HIV-related stigma in a cohort of women living with HIV (WLWH) from across Ontario, Canada during pregnancy and early postpartum. From March 2011 to December 2012, WLWH ≥ 18 years (n = 77) completed a study instrument measuring independent variables including sociodemographic characteristics, perceived stress, depression symptoms, social isolation, social support and perceived racism in the third trimester and 3, 6 and 12 months postpartum. Multivariable linear regression was employed to explore the relationship between HIV-related stigma and multiple independent variables. HIV-related stigma generally increased from pregnancy to postpartum; however, there were no significant differences in HIV-related stigma across all study time points. In multivariable regression, depression symptoms and perceived racism were significant predictors of overall HIV-related stigma from pregnancy to postpartum. The present analysis contributes to our understanding of HIV-related stigma throughout the pregnancy-motherhood trajectory for WLWH including the interactional relationship between HIV-related stigma and other psychosocial variables, most notably, depression and racism.

  3. Urinary Phthalate Metabolites and Biomarkers of Oxidative Stress in a Mexican-American Cohort: Variability in Early and Late Pregnancy

    2016-03-01

    Full Text Available People are exposed to phthalates through their wide use as plasticizers and in personal care products. Many phthalates are endocrine disruptors and have been associated with adverse health outcomes. However, knowledge gaps exist in understanding the molecular mechanisms associated with the effects of exposure in early and late pregnancy. In this study, we examined the relationship of eleven urinary phthalate metabolites with isoprostane, an established marker of oxidative stress, among pregnant Mexican-American women from an agricultural cohort. Isoprostane levels were on average 20% higher at 26 weeks than at 13 weeks of pregnancy. Urinary phthalate metabolite concentrations suggested relatively consistent phthalate exposures over pregnancy. The relationship between phthalate metabolite concentrations and isoprostane levels was significant for the sum of di-2-ethylhexyl phthalate and the sum of high molecular weight metabolites with the exception of monobenzyl phthalate, which was not associated with oxidative stress at either time point. In contrast, low molecular weight metabolite concentrations were not associated with isoprostane at 13 weeks, but this relationship became stronger later in pregnancy (p-value = 0.009 for the sum of low molecular weight metabolites. Our findings suggest that prenatal exposure to phthalates may influence oxidative stress, which is consistent with their relationship with obesity and other adverse health outcomes.

  4. Osteopontin is expressed in the mouse uterus during early pregnancy and promotes mouse blastocyst attachment and invasion in vitro.

    Directory of Open Access Journals (Sweden)

    Qian-Rong Qi

    Full Text Available Embryo implantation into the maternal uterus is a decisive step for successful mammalian pregnancy. Osteopontin (OPN is a member of the small integrin-binding ligand N-linked glycoprotein family and participates in cell adhesion and invasion. In this study, we showed that Opn mRNA levels are up-regulated in the mouse uterus on day 4 and at the implantation sites on days 5 and 8 of pregnancy. Immunohistochemistry localized the OPN protein to the glandular epithelium on day 4 and to the decidual zone on day 8 of pregnancy. OPN mRNA and proteins are induced by in vivo and in vitro decidualization. OPN expression in the endometrial stromal cells is regulated by progesterone, a key regulator during decidualization. As a secreted protein, the protein level of OPN in the uterine cavity is enriched on day 4, and in vitro embryo culturing has indicated that OPN can facilitate blastocyst hatching and adhesion. Knockdown of OPN attenuates the adhesion and invasion of blastocysts in mouse endometrial stromal cells by suppressing the expression and enzymatic activity of matrix metalloproteinase-9 in the trophoblast. Our data indicated that OPN expression in the mouse uterus during early pregnancy is essential for blastocyst hatching and adhesion and that the knockdown of OPN in mouse endometrial stroma cells could lead to a restrained in vitro trophoblast invasion.

    Maternal plasma levels of human placental lactogen (HPL) are decreased in hypertensive pregnancies and the concentration is related to the severity of the condition. Of infants who had HPL concentrations in the fetal danger zone (more than 2 SD's below normal mean) 75 per cent developed fetal distress, neonatal asphyxia or were light for dates. Patients who are identified in this way have lighter infants and placentae than their unidentified counterparts with normal HPL levels.

    Background The objective of this study was to validate previously published rates of remission, continuation, and incidence of broadly defined eating disorders during pregnancy. The previous rate modeling was done by our group (Bulik et al. 2007) and yielded participants halfway into recruitment of the planned 100,000 pregnancies in the Norwegian Mother and Child (MoBa) Cohort at the Norwegian Institute of Public Health. This study aimed to internally validate the findings with the completed cohort. Methods 77267 pregnant women enrolled at 17 weeks gestation between 2001 and 2009 were included. Participants were split into a “training” sample (n=41243) based on participants in the MoBa version 2 dataset of the original study and a “validation” sample (n=36024) comprising individuals in the MoBa version 5 dataset that were not in the original study (Bulik et al. 2007). Internal validation of all original rate models involved fitting a calibration model to compare model parameters between the “training” and “validation” samples as well as bootstrap estimates of bias in the entire version 5 dataset. Results Remission, continuation, and incidence estimates from the “training” sample remained stable when evaluated via a split sample validation procedure. Pre-pregnancy prevalence estimates in the “validation” sample were 0.1% for anorexia nervosa, 1.0% for bulimia nervosa (BN), 3.3% for binge eating disorder (BED), and 0.1% for purging disorder (EDNOS-P). In early pregnancy, estimates were 0.2% for BN, 4.8% for BED, and eating disorders during pregnancy. Eating disorders during pregnancy were relatively common, occurring in nearly 1 in every 20 women, although almost all were cases of BED. Pregnancy was a window of remission from BN but a window of vulnerability for onset and continuation of BED.

    Induction of labor among pregnant women with high levels of total bile acid (TBA) is common among clinicians. We examined, if women with intrahepatic cholestasis of pregnancy (ICP) and TBA ≥ 40 μmol/l have a higher risk of maternal-fetal complications, when labor is induced at 37 weeks of gestation, compared with induction of labor at term in women with low-risk ICP. Retrospective cohort study of 16,185 women delivering at Roskilde University Hospital in the period 2006-2011. Women with high-risk ICP (TBA ≥ 40 μmol/l) had labor induced at 37 weeks of gestation; women with low-risk ICP (TBA < 40 μmol/l) at term. Mode of delivery, duration of induction procedures, highest level of TBA and alanine aminotransferase (ALT) and for the neonates: Apgar scores at 5 min, umbilical cord pHs and SBEs, NICU admissions and birthweights. The incidences of ICP was 1.2 % (95 % CI 1.05-1.39 %) altogether and for high-risk ICP 0.4 % (95 % CI 0.27-0.46 %). No difference was found in mode of delivery, length of induction of labor nor in neonatal outcomes, except for an expected difference in birthweight. In high-risk ICP, ALT was not raised in 10.3 % (95 % CI 2.5-18.2 %). Early induction of labor at 37 weeks of gestation seems justified in high-risk ICP, as, except for abbreviating gestational age by 9 days with 296 g smaller babies, induction of labor was not followed by detectable maternal-fetal disadvantages and is favored by an expected major reduction in ICP stillbirth risk.

    Previous studies have investigated the lower embryo implantation rates in women with polycystic ovary syndrome, obesity and type 2 diabetes, and specifically the association between the abnormal oocyte and embryo and hyperinsulinemia. The importance of hyperinsulinemia on maternal endometrium receptivity remains to be elucidated. The present study used a hyperinsulinemic mouse model to determine whether hyperinsulinemia may affect endometrial receptivity. An insulin intervention mouse model was first established. The serum levels of insulin, progesterone and estradiol were subsequently detected by ELISA assay analysis. The number of implantation sites was recorded using Trypan blue dye and the morphology of mice uteri was investigated using hematoxylin and eosin staining. The expression levels of molecular markers associated with endometrial receptivity were detected by reverse transcription-quantitative polymerase chain reaction, western blotting and immunohistochemistry analyses. Finally, the importance of mechanistic target of rapamycin (mTOR) expression following insulin treatment was determined. Mice treated with insulin developed insulin resistance and hyperinsulinemia. The number of implantation sites following insulin treatment did not differ between the control and insulin-treated groups. Additionally, no significant morphological alterations in mice uteri between control and insulin-treated groups were observed. However, the expression levels of estrogen receptor (Esr) 1, Esr2, progesterone receptor and homeobox A10 associated with endometrial receptivity, were imbalanced during endometrium receptivity when maternal hyperinsulinemia was induced. Western blot analysis revealed that expression levels of endometrial phosphorylated (p)-mTOR and p-ribosomal protein S6 kinase β-1 were significantly greater in the insulin-treated group. These results demonstrated that although an embryo may implant into endometrium, mice endometrium receptivity in early

    Randomized clinical trials (RCTs) demonstrated the equal efficacy of urinary human chorionic gonadotropin (uhCG) and recombinant hCG (rhCG) products in in vitro fertilisation (IVF). However, limitations inherent with RCTs necessitate the reinforcement of RCT results in real-life. We retrospectively analyzed pregnancies after treatment with rhCG and uhCG products (n = 391, and 96, resp.). We found that laboratory-verified pregnancy occurred more frequently in rhCG patients than in those on uhCG (43% versus 30%, P = 0.02). The association remains significant (P = 0.002) after its adjustment for clinical characteristics. The prevalence of laboratory-verified pregnancies was higher with GnRH agonist use (P = 0.012) and BMI under 30 kg/m(2) (P = 0.053) while decreased the age (P = 0.014) and the number of previous failed attempts (P = 0.08). Similar (but not significant) trends were observed with rates of pregnancy filled the 24th week. These results reinforce RCTs supporting the notion that rhCG is more efficient as uhCG during IVF.

    Metabolic diseases induced by metabolic syndrome (MS) have been increased during the past two decades. During healthy pregnancy maternal organs and placenta are challenged to adapt to the increasingly physiological changes. In addition to the increasingly proatherogenic MS, pregnant woman develops a high cardiac output, hypercoagulability, increased inflammatory activity and insulin resistance with dyslipidemia. The MS describes a cluster of metabolic changes associated with an impact on the physiology of many organs. While the metabolic syndrome is directly responsible for the development of atherosclerotic cardiovascular disease, additional impact on human pregnancy like preterm delivery with low-birth-weight infants as well as the development of diseases such as diabetes, preeclampsia and hypertension. Recent evidence suggests that MS is originated in fetal life in association with maternal nutrition during pregnancy and fetal programming which apparently increases the susceptibility for MS in children and later life. This review will describe the MS in association with the origin of the emerging diseases during pregnancy such as diabetes, preeclampsia and others. The influence of perinatal environment and maternal diet and smoking on MS as well as the genetic biomarkers of MS will be described.

    We investigated population-based vital records of the seventeenth and eighteenth century French Canadian population to assess the effects of marriage season on the outcome of the first births under natural fertility conditions (n=21,698 marriages). Promptness of the first successful conception after marriage differed according to marriage season; the proportion of marriages with a marriage-first birth interval of 8.0-10.0 months was lowest (34%) for marriages in August-October (P=0.001). Although the male/female sex ratio of the babies born with an interval of 8.0-10.0 months was generally higher (1.10) than those with an interval of 10.0-24.0 months (1.05), the marriages in August-October resulted in a significantly reduced sex ratio (0.96) among only the prompt conceptions (P=0.026). We discuss whether this seasonal reduction of the sex ratio could be partly explained by a clustered pregnancy loss of male zygotes in early pregnancy.

    Highlights: Black-Right-Pointing-Pointer Spiral artery (SA) wall remodeling (SAR) is ill-defined and clinically important. Black-Right-Pointing-Pointer SA muscular phenotype prior to and during SAR in mice is underexplored. Black-Right-Pointing-Pointer SA muscular wall consists of contractile and non-contractile components. Black-Right-Pointing-Pointer SA wall non-contractile component may be synthetic smooth muscle. Black-Right-Pointing-Pointer Timing and extent of SA wall contractile component loss is revealed. -- Abstract: During pregnancy the walls of decidual spiral arteries (SAs) undergo clinically important structural modifications crucial for embryo survival/growth and maternal health. However, the mechanisms of SA remodeling (SAR) are poorly understood. Although an important prerequisite to this understanding is knowledge about the phenotype of SA muscular wall prior to and during the beginning of mouse SAR, this remains largely unexplored and was the main aim of this work. Using histological and immunohistochemical techniques, this study shows for the first time that during early mouse gestation, from embryonic day 7.5 (E7.5) to E10.5, the decidual SA muscular coat is not a homogeneous structure, but consists of two concentric layers. The first is a largely one cell-thick sub-endothelial layer of contractile mural cells (positive for {alpha}-smooth muscle actin, calponin and SM22{alpha}) with pericyte characteristics (NG2 positive). The second layer is thicker, and evidence is presented that it may be of the synthetic/proliferative smooth muscle phenotype, based on absence ({alpha}-smooth muscle actin and calponin) or weak (SM22{alpha}) expression of contractile mural cell markers, and presence of synthetic smooth muscle characteristics (expression of non-muscle Myosin heavy chain-IIA and of the cell proliferation marker PCNA). Importantly, immunohistochemistry and morphometrics showed that the contractile mural cell layer although prominent at E7.5-E8

    Intrahepatic cholestasis of pregnancy (ICP) is the commonest gestational liver disease. The risk of adverse fetal outcome has been associated with the severity of maternal hypercholanemia after diagnosis. To investigate whether there is a relationship between the severity and timing of onset of hypercholanemia and the risk of meconium-stained amniotic fluid (MSAF) and adverse neonatal events. The study included 382 pregnancies complicated by ICP managed at a referral hospital in Buenos Aires (Argentina) between June 2009 and December 2013. The patients were classified into three groups according to the severity of hypercholanemia at diagnosis; mild (10-19.9 μmol/L), moderate (20-39.9 μmol/L) and severe (≥40 μmol/L). Their clinical characteristics and pregnancy outcomes were investigated in a prospective observational study. Higher risk of MSAF was observed when ICP appeared early in gestation or when hypercholanemia was more severe. Taking both parameters into account an MSAF risk factor (MRF) was defined. Based on a model of positive/negative predictive values, a cut-off point of MRF = 3 was selected, which prioritized sensitivity versus specificity. In ICP patients with MRF>3, the probability of MSAF was enhanced 4-fold. An increase in the frequency of MSAF was also associated with higher serum levels at diagnosis of alanine transaminase, alkaline phosphatase and direct bilirubin. The risk of MSAF is associated not only with the magnitude of hypercholanemia at diagnosis but also with the early gestational onset of raised maternal serum bile acids.

    Full Text Available Pregnant women with gestational diabetes mellitus (GDM are reported to be at increased risk for infections of the genital tract. This study aimed to compare the prevalence of asymptomatic bacterial vaginosis (BV and Candida colonization at early gestation between pregnant women with and without diabetic conditions during pregnancy. We included data from 8, 486 singleton pregnancies that underwent an antenatal infection screen-and-treat programme at our department. All women with GDM or pre-existing diabetes were retrospectively assigned to the diabetic group (DIAB, whereas non-diabetic women served as controls (CON. Prevalence for BV and Candida colonization was 9% and 14% in the DIAB group, and 9% and 13% in the CON group, respectively (n.s.. No significant difference regarding stillbirth and preterm delivery (PTD, defined as a delivery earlier than 37 + 0 (37 weeks plus 0 days weeks of gestation was found. We could not find an increased risk of colonization with vaginal pathogens at early gestation in pregnant women with diabetes, compared to non-diabetic women. Large prospective studies are needed to evaluate the long-term risk of colonization with vaginal pathogens during the course of pregnancy in these women.

    There is promising evidence that poverty-targeted cash transfer programs can have positive impacts on adolescent transitions to adulthood in resource poor settings, however existing research is typically from small scale programs in diverse geographic and cultural settings. We provide estimates of the impact of a national unconditional cash transfer program, the Kenya Cash Transfer for Orphans and Vulnerable Children, on pregnancy and early marriage among females aged 12 to 24, four years after program initiation. The evaluation was designed as a clustered randomized controlled trial and ran from 2007 to 2011, capitalizing on the existence of a control group, which was delayed entry to the program due to budget constraints. Findings indicate that, among 1549 females included in the study, while the program reduced the likelihood of pregnancy by five percentage points, there was no significant impact on likelihood of early marriage. Program impacts on pregnancy appear to work through increasing the enrollment of young women in school, financial stability of the household and delayed age at first sex. The Kenyan program is similar in design to most other major national cash transfer programs in Eastern and Southern Africa, suggesting a degree of generalizability of the results reported here. Although the objective of the program is primarily poverty alleviation, it appears to have an important impact on facilitating the successful transition of adolescent girls into adulthood.

    The influence of male-induced early puberty on female reproductive rate was determined in three lines of mice differing in litter size and body weight. The lines originated from a single base population and had undergone 20 generations of selection for the following criteria: large litter size at birth (L(+)), large litter size and small 6-week body weight (L(+)W(-)), or small litter size and large 6-week body weight (L(-)W(+)). Females were paired with a mature intact male of the same line at 3, 5 or 7 weeks of age. Mean mating age, averaged over lines, was 26.5 ± .3, 38.3 ± .3 and 52.7 ± .3 days. Exposure to a mature male accelerated female sexual maturation in each line. When contrasted with their sibs mated at a later age, early-pregnant females from each line exhibited a decline in one or more component of reproductive performance, suggesting that the physiological state of the very young female was not optimum for normal pregnancy. In comparisons of early and later mating ages, all three lines showed a decreased littering rate at first mating, number born alive, and individual birth weight of progeny adjusted for litter size; L(+) and L(+)W(-) mice showed an increased perinatal mortality rate; L(+) and L(-)W(+) had a reduction in litter size at birth. When the L(+), L(+)W(-) and L(-)W(+) lines were compared with an unselected strain and a line selected for high postweaning gain in similar experiments, a genotype by environment interaction was apparent since all lines did not respond in a similar manner to early mating. The line ranking for litter size at birth for each age at male-exposure was L(+)>L(+)W(-)>L(-)W(+), despite the significant line by age interaction. When litter size was adjusted by covariance for body weight at mating, the significant effects of age at male-exposure and line by age interaction were eliminated. All fertile females were remated after they had weaned their first litter to obtain information on litter size in parity two. Line

    Maternal early pregnancy lipid profile might influence offspring's lipids and glycaemic control, through an increased offspring's fat percentage. This explorative study investigates whether maternal early pregnancy lipid profile is associated with offspring's lipids and glycaemic control independently of offspring's fat percentage and if these associations are mediated by offspring's fat percentage. Possible sex differences in these associations are also examined. 1133 mother-child pairs of the prospective ABCD-study were included. Maternal non-fasting lipids were collected in early pregnancy: triglycerides, total cholesterol (TC), Apolipoprotein A1 (ApoA1), Apolipoprotein B (ApoB) and free fatty acids (FFA). Fasting triglycerides, TC, high density lipoprotein (HDL), low density lipoprotein (LDL), glucose and C-peptide were assessed in offspring aged 5-6 years and HOMA2-IR was calculated. After adjustment for covariates, strongest associations were found between maternal TC and offspring's TC (boys β(95%CI) = 0.141 (0.074-0.207); girls β(95%CI) = 0.268 (0.200; 0.336)) and LDL (boys β(95%CI) = 0.114 (0.052; 0.176); girls β(95%CI) = 0.247 (0.181-0.312)), maternal ApoB and offspring's TC (boys β(95%CI) = 0.638 (0.311-0.965); girls β(95%CI) = 1.121 (0.766-1.475)) and LDL (boys β(95%CI) = 0.699 (0.393-1.005); girls β(95%CI) = 1.198 (0.868-1.529)), and maternal ApoA1 and offspring's HDL (only boys β(95%CI) = 0.221 (0.101-0.341)). No significant association was found between maternal lipids and offspring's glycaemic control, and offspring's fat percentage played no mediating role. Maternal early pregnancy lipid profile is associated with offspring's lipid profile in childhood, with overall stronger associations in girls. This study provides further evidence that lowering lipid levels during pregnancy might be beneficial for the long term health of the offspring.

    To investigate the maternal serum concentration of human placental growth hormone (hPGH) in trisomy 21 and trisomy 18 pregnancies at 11 to 13 weeks of gestation and to examine the possible association between fetal nuchal translucency (NT) thickness and maternal serum free beta-human chorionic gonadotrophin (beta-hCG) and pregnancy-associated plasma protein-A (PAPP-A). The maternal serum concentration of hPGH at 11 to 13 weeks was measured in a case-control study from 28 pregnancies with fetal trisomy 21, 28 with trisomy 18 and 112 pregnancies with euploid fetuses. The median hPGH multiple of the median (MoM) in trisomy 21 and trisomy 18 pregnancies were compared with euploid pregnancies. Serum hPGH was significantly lower in trisomy 21 (0.93 MoM) and trisomy 18 (0.62 MoM) compared to euploid pregnancies (1.02 MoM). There was a significant association between serum hPGH and PAPP-A in both the euploid (r = 0.258, p = 0.006) and trisomy 21 pregnancies (r = 0.410, p = 0.030) but not in trisomy 18 pregnancies (p = 0.445). In the first trimester, serum hPGH in trisomy 21 and trisomy 18 pregnancies is reduced. This is the opposite of findings in previous studies reporting that in the second trimester, trisomy 21 and 18 pregnancies have increased hPGH. Copyright (c) 2010 John Wiley & Sons, Ltd.

    To identify dietary factors related to the risk of gaining weight outside recommendations for pregnancy weight gain and birth outcome. An observational study with free-living conditions. Four hundred and ninety five healthy pregnant Icelandic women. The dietary intake of the women was estimated with a semiquantitative food frequency questionnaire covering food intake together with lifestyle factors for the previous 3 months. Questionnaires were filled out at between 11 and 15 weeks and between 34 and 37 weeks gestation. Comparison of birth outcome between the three weight gain groups was made with ANOVA and Bonferroni post hoc tests. Dietary factors related to at least optimal and excessive weight gain during pregnancy were represented with logistic regression controlling for potential confounding. Of the women, 26% gained suboptimal and 34% excessive weight during pregnancy. Women in late pregnancy with at least optimal, compared with women with suboptimal, weight gain were eating more (OR = 3.32, confidence interval (CI)=1.81-6.09, P lifestyle modifications affecting consequent weight gain during pregnancy. They are most likely to gain excessive weight and therefore most likely to suffer pregnancy and delivery complications and struggle with increasing overweight and obesity after giving birth.

    More than half of all cases of preeclampsia occur in healthy first-time pregnant women. Our aim was to develop a method to predict those at risk by combining clinical factors and measurements of biomarkers in women recruited to the Screening for Pregnancy Endpoints (SCOPE) study of low-risk nulliparous women. Forty-seven biomarkers identified on the basis of (1) association with preeclampsia, (2) a biological role in placentation, or (3) a role in cellular mechanisms involved in the pathogenesis of preeclampsia were measured in plasma sampled at 14 to 16 weeks' gestation from 5623 women. The cohort was randomly divided into training (n=3747) and validation (n=1876) cohorts. Preeclampsia developed in 278 (4.9%) women, of whom 28 (0.5%) developed early-onset preeclampsia. The final model for the prediction of preeclampsia included placental growth factor, mean arterial pressure, and body mass index at 14 to 16 weeks' gestation, the consumption of ≥3 pieces of fruit per day, and mean uterine artery resistance index. The area under the receiver operator curve (95% confidence interval) for this model in training and validation cohorts was 0.73 (0.70-0.77) and 0.68 (0.63-0.74), respectively. A predictive model of early-onset preeclampsia included angiogenin/placental growth factor as a ratio, mean arterial pressure, any pregnancy loss preeclampsia in populations of mixed parity and risk. In nulliparous women, combining multiple biomarkers and clinical data provided modest prediction of preeclampsia. © 2014 American Heart Association, Inc.

    The purpose of the present study was to investigate the relationship between psychosocial characteristics and broadly defined bulimia nervosa during early pregnancy, including factors associated with continuation, incidence and remission. A total of 41 157 women completed questionnaires at approximately gestation week 18, including items on eating disorders and psychosocial characteristics as a part of Norwegian Mother and Child Cohort Study conducted by the Norwegian Institute of Public Health. Incident bulimia nervosa during the first trimester was significantly associated with symptoms of anxiety and depression and low self-esteem and life satisfaction, whereas remission was significantly associated with higher self-esteem and life satisfaction. Continuation was not significantly related to any of the psychosocial variables tested. Onset of bulimia nervosa during pregnancy is associated with mood and anxiety symptoms. Remission of bulimic symptoms and new onset of bulimia nervosa are associated with opposite profiles of self-esteem, and life satisfaction measures.

    Full Text Available Abstract Background The development of the in vitro cell culture model has greatly facilitated the ability to study gene expression and regulation within human tissues. Within the human uterus, the upper (fundal segment and the lower segment may provide distinct functions throughout pregnancy and during labour. We have established primary cultured human myometrial cells, isolated from both upper and lower segment regions of the pregnant human uterus, and validated them for the purpose of studying human pregnancy and labour. The specific objectives of this study were to monitor the viability and characterize the expression profile using selected cellular, contractile and pregnancy associated markers in the primary cultured human myometrial cells. Labour has been described as an inflammatory process; therefore, the ability of these cells to respond to an inflammatory stimulus was also investigated. Methods Myometrial cells isolated from paired upper segment (US and lower segment (LS biopsies, obtained from women undergoing Caesarean section deliveries at term prior to the onset of labour, were used to identify expression of; α smooth muscle actin, calponin, caldesmon, connexin 43, cyclo-oxygenase-2 (COX-2, oxytocin receptor, tropomyosin and vimentin, by RT-PCR and/or immunocytochemistry. Interleukin (IL-1β was used to treat cells, subsequently expression of COX-2 mRNA and release of interleukin-8 (CXCL8, were measured. ANOVA followed by Bonferroni’s multiple comparisons test was performed. Results We demonstrate that US and LS human myometrial cells stably express all markers examined to at least passage ten (p10. Connexin 43, COX-2 and vimentin mRNA expression were significantly higher in LS cells compared to US cells. Both cell populations respond to IL-1β, demonstrated by a robust release of CXCL8 and increased expression of COX-2 mRNA from passage one (p1 through to p10. Conclusions Isolated primary myometrial cells maintain expression of

    Full Text Available OBJECTIVE: Much controversy still exists about maternal-to-infant transmission of human papillomavirus (HPV infection, specifically about the magnitude of the risk and the route and timing of such vertical transmission. This prospective cohort study examines the risk of vertical transmission of maternal HPV in each trimester of pregnancy. STUDY DESIGN: One hundred fifty three healthy pregnant women were followed longitudinally throughout pregnancy and cervical swabs obtained in each trimester and postpartum for HPV detection. Cord blood, neonatal nasopharyngeal aspirates, and placental biopsies were collected at delivery. DNA isolation, polymerase chain reaction, and hybridization were performed using the GG HPV Genotyping Chip Kit (Goodgene Inc., Seoul, Korea. Detection of HPV in neonates was defined as the presence of HPV DNA in either cord blood or neonatal nasopharyngeal aspirate. RESULTS: HPV DNA was detected in 14%(22/153 of healthy women in the first trimester, 18%(22/124 in the second trimester, and 10%(15/153 in the third trimester; 24%(37/153 were positive for HPV DNA on at least one occasion in pregnancy. At birth, 5.2%(8/153 of neonates were HPV DNA positive. Seven of these eight infants were born to HPV-positive mothers. Placental HPV DNA was positive in 3.3%(5/152 of cases, and all five cases were from mothers with at least one HPV-positive test. Detection of HPV DNA in neonates was associated with detection of HPV in mothers during any of the three trimesters of pregnancy. CONCLUSION: HPV DNA was detected at birth in 5.2%(8/153 of neonates born to healthy women, and was associated with the detection of HPV in mothers during any of the three trimesters of pregnancy.

    Full Text Available Dendritic cells (DCs are critically involved in the determination of immunity versus tolerance. Hence, DCs are key regulators of immune responses either favoring or disfavoring fetal survival. Several factors were proposed to modulate DC phenotype and function during preg-nancy. Here, we studied whether the pregnancy hormone human Chorionic Gonadotropin (hCG is involved in DC regulation.In vitro, bone-marrow-derived DCs (BMDCs were stimulated in the presence or absence of urine-purified (uhCG or recombinant hCG (rhCG preparations. Subsequently, BMDC matu-ration was assessed. Cytokine secretion of activated BMDCs and their capability to enforce TH1, TH2, TH17 or Treg cell differentiation was determined after rhCG treatment. Moreover, the in vivo potential of hCG-modulated BMDCs to influence pregnancy outcome, Treg cell number and local cytokine expression was evaluated after adoptive transfer in a murine abor-tion-prone model before and after conception. Both hCG preparations impaired the maturation process of BMDCs. rhCG treatment did nei-ther alter cytokine secretion by BMDCs nor their ability to drive TH1, TH2 or TH17 differen-tiation. rhCG-treated BMDCs augmented the number of Treg cells within the T cell popula-tion. Adoptive transfer of rhCG-treated BMDCs after conception did not influence pregnancy outcome. However, transfer of hCG-treated BMDCs prior to mating had a protective effect on pregnancy. This positive effect was accompanied by increased Treg cell numbers and decidual IL-10 and TGF-β expression. Our results unveil the importance of hCG in retaining DCs in a tolerogenic state, thereby promoting Treg cell increment and supporting fetal survival.

    This study aimed to assess the impact of wearing compression stockings on women's quality of life (QoL) associated with nausea and vomiting in early pregnancy (NVP). In this randomized, open, single-center, crossover study, 74 women were assigned 1:1 to 2 weeks with compression stockings followed by 2 weeks without or vice versa. The main outcomes were NVP-associated QoL, leg-related QoL, and dizziness, as assessed by the Nausea and Vomiting in Pregnancy Quality of Life (NVPQOL) questionnaire, Chronic Venous Disease Quality of Life (CIVIQ) questionnaire, and questions on dizziness at baseline and after each 2-week period, respectively. Daily NVP was assessed using the modified Pregnancy-Unique Quantification of Emesis and Nausea (PUQE) questionnaire. Data were analyzed using Pearson's chi-square and independent t-tests. Fifty-eight women completed the study. QoL scores improved with compression treatment; changes in mean total scores were as follows: NVPQOL, -36.7 with compression vs -21.7 without (P<0.0001); and CIVIQ, -4.5 with compression vs +1.4 without (P=0.001). Mean dizziness scores were -3.2 with compression vs -0.4 without (P<0.0001). PUQE mean total score (standard deviation) was 4.9 (2.3) with compression vs 5.5 (2.2) without (P=0.042). Wearing of compression stockings in early pregnancy may improve nausea and vomiting-associated symptoms in addition to improving QoL factors.

    Full Text Available BACKGROUND: Heme oxygenase-1 (HO-1 concentrations have been recently reported to be elevated in impaired glucose tolerance and type 2 diabetes mellitus (T2DM. However, no study has examined the association between HO-1 concentrations and gestational diabetes mellitus (GDM. METHODS: In a case-control study, nested within a prospective cohort of pregnant women (186 GDM cases and 191 women who remained eu-glycemic through pregnancy, we assessed the association of maternal serum HO-1 concentrations, measured in samples collected at 16 weeks gestation, on average, with subsequent risk of GDM. Maternal serum HO-1 concentrations were determined using ELISA. We fitted multivariate logistic regression models to derive estimates of odds ratios (ORs and 95% confidence intervals (CIs. RESULTS: Median serum HO-1 concentrations in early pregnancy were lower in women who subsequently developed GDM compared with those who did not (1.60 vs. 1.80 ng/mL, p-value=0.002. After adjusting for maternal age, race, family history of T2DM and pre-pregnancy body mass index, women with HO-1 ≥ 3.05 ng/mL (highest decile experienced a 74% reduction of GDM risk (95% CI; 0.09-0.77 compared with women whose concentrations were<1.23 ng/mL (lowest quartile. CONCLUSION: Serum HO-1 concentrations were inversely associated with subsequent GDM risk. These findings underscore the role of oxidative stress in the pathogenesis of GDM. Additional studies are warranted to confirm the clinical utility of serum HO-1 in diagnosis of GDM, particularly in the early pregnancy.

  14. Early embryonic failure: Expression and imprinted status of candidate genes on human chromosome 21

    Two cases of maternal uniparental (hetero)disomy for human chromosome 21 (mUPD21) have been identified in a systematic search for UPD in 23 cases of early embryonic failure (EEF). Bi-parental origin of the other chromosome pairs was confirmed using specific VNTR probes or dinucleotide repeat analysis. Both maternally and paternally derived isochromosomes 21q have previously been identified in two individuals with normal phenotypes. Full UPD21 has a different mechanism of origin than uniparental isochromosome 21q and its effect on imprinted genes and phenotypic outcome will therefore not necessarily be the same. EEF associated with mUPD21 suggests that developmentally important genes on HSA 21 may be imprinted such that they are only expressed from either the maternally or paternally derived alleles. We have searched for monoallelic expression of candidate genes on HSA 21 in human pregnancy (CBS, IFNAR, COL6A1) using intragenic DNA polymorphisms. These genes were chosen either because their murine homologues lie in imprinted regions or because they are potentially important in embryogenesis. Once imprinted candidate genes have been identified, their methylation status and expression in normal, early embryonic failure and uniparental disomy 21 pregnancies will be studied. At the same time, a larger number of cases of EEF are being examined to further investigate the incidence of UPD21 in this group.

    Arachidonic acid is metabolized by means of P450 isoenzyme(s) to form epoxyeicosatrienoic acids (EETs) and their corresponding dihydroxy derivatives (DHETs). In the present study, we established the presence in human urine of 8,9-, 11,12-, and 14,15-EETs and their corresponding DHETs by developing quantitative assays and using negative ion, chemical ionization GC/MS and octadeuterated internal standards. Urinary excretion of 8,9- and 11,12-DHET increased in healthy pregnant women compared with nonpregnant female volunteers. By contrast, excretion of 11,12-DHET and 14,15-DHET, but not the 8,9-DHET regioisomer, increased even further in patients with pregnancy-induced hypertension. Intravenous administration of (3H)14,15-EET to three dogs markedly increased its DHET in plasma. The terminal half-life ranged from 7.9-12.3 min and the volume of distribution (3.5-5.3 liters) suggested limited distribution outside the plasma compartment. Negligible radioactivity was detected in urine; this fact infers that under physiological circumstances, urinary DHETs largely derive from the kidney. That P450 metabolites of arachidonic acid are formed in humans supports the hypothesis that these metabolites contribute to the physiological response to normal pregnancy and the pathophysiology of pregnancy-induced hypertension.

    Nitric oxide was proposed as an endogenous inhibitor of myometrial contractility during pregnancy. Carbon monoxide (CO) like nitric oxide increases cGMP and is generated during the degradation of heme to biliverdin IX by hemeoxygenases (HO). Here we report that the expression of both HO-1 (inducible) and HO-2 (constitutive) were > 15-fold higher in pregnant myometrium compared to nonpregnant myometrium (n = 4, P synthesis (n = 4, P tin protoporphyrin IX (20 microM). This study clearly demonstrates the expression of HO in the human myometrium and shows that its induction produces CO that limits uterine contractility in pregnant myometrium indicating a role for the HO-CO-cGMP pathway in the maintenance of the quiescent state of the uterus during pregnancy.

    Early-pregnancy lifestyle (EPL) could influence the development of gestational diabetes mellitus(GDM), depending on the diagnostic criteria used. We studied EPL in 1750 pregnant women using Carpenter-Coustan criteria(CCc), and in 1526 with the International Association of Diabetes and Pregnancy Study Groups criteria(IADPSGc). GDM risk factors were assessed in women between 24 and 28 weeks of gestational age during two consecutive years. A semiquantitative frequent-food-consumption questionnaire was used to evaluate lifestyle during pregnancy. Multiple logistic regression analysis was conducted to assess GDM risk with different lifestyle patterns. Using IADPSGc, the GDM ORs (95%CI) for intake/week were: nuts >3 times: 0.59 (0.39-0.91; p < 0.015), refined cereals ≤1 serving: 0.72(0.58-0.89; p < 0.003), juices <4 servings: 0.77 (0.62-0.95; p < 0.017), cookies and pastries <4 servings: 0.71(0.57-0.89; p < 0.003) as compared to opposite habits. No significant nutritional patterns were found to be significant using CCc. The OR (95%CI) for GDM with none of the four risk patterns as compared to having three-four risk factors was 0.21(0.07-0.62; p < 0.005), remaining significant after stratification by BMI, age, obstetric events, parity and family history. The multiple logistic regression model including nutritional categories and pregestational BMI, age, obstetric history, parity, personal/family history, had an area under the curve(AUC) of the receiver operating curve(ROC) for the probability to predict GDM of 0.66 (CI 95%: 0.63-0.69; p < 0.001). Our study is the first to identify four early-pregnancy nutritional patterns associated with the GDM when using IADPSGc. Adherence to a low-risk nutritional pattern from early pregnancy on could be an effective strategy for GDM prevention.

    to investigate women's physical activity levels, diet and gestational weight gain, and their experiences and motivations of behavior change. analysis of cross-sectional data collected during a longitudinal, cohort study examining physiological, psychological, sociodemographic, and self-reported behavioural measures relating to bodyweight. women recruited from routine antenatal clinics at the Nottingham University Hospitals NHS Trust. 193 women ≤27 weeks gestation and aged 18 years or over. MEASUREMENTS & FINDINGS: measurements included weight and height, the Dietary Instrument for Nutrition Education (Brief Version), the International Physical Activity Questionnaire (Short Form), and open questions of perceptions of behaviour change. 50.3% (n=97) were overweight/obese, and women gained 0.26kg/wk (IQR 0.34kg/wk) since conception. The majority consumed low levels of fat (n=121; 63.4%), high levels of unsaturated fat (n=103; 53.9%), and used a dietary supplement (n=166; 86.5%). However, 41% (n=76) were inactive, 74.8% (n=143) did not consume high levels of fibre, and 90.0% (n=171) consumed less than 5 portions of fruit and vegetables a day. Body mass index category was not associated with diet, physical activity levels, or gestational weight gain. Themes generated from open-questions relating to behaviour change were: (1) Risk management, (2) Coping with symptoms, (3) Self-control, (4) Deviation from norm, (5) Nature knows best. early pregnancy is a period of significant and heterogeneous behaviour change, influenced by perceptions of risk and women's lived experience. Behaviour was influenced not only by perceptions of immediate risk to the fetus, but also by the women's lived experience of being pregnant. There are exciting opportunities to constructively reframe health promotion advice relating to physical activity and diet in light of women's priorities. The need for individualized advice is highlighted, and women across all body mass index categories would

    Despite documented effects on fetal brain development, little is currently known about the relationship between maternal pregnancy hypertension and child neuropsychological outcomes. This brief report examined the association between maternal hypertension during pregnancy and children's social cognition and executive functioning when children were 18 months, 3 years, and 4.5 years. A community sample of 501 families (23 hypertensive mothers; 478 nonhypertensive) was recruited when children were newborns. Social cognition (including theory of mind [ToM]) and executive functioning (EF) were measured using a battery of age-appropriate standardized and/or observational tasks. Information on pregnancy and prenatal factors were measured via maternal report when children were newborns. After controlling for prenatal and demographic covariates, the presence of hypertension difficulties during pregnancy was associated with all measures of social cognition, ToM, and EF. A secondary analysis comparing the hypertension group (n = 23) to a nonhypertensive matched control group (n = 23) supported the effect of pregnancy hypertension on children's social-cognitive and EF development. Future studies using obstetrical records are encouraged based on these preliminary findings.

    Thyroid hormones are essential for normal brain development in vertebrates. In humans, abnormal maternal thyroid hormone levels during early pregnancy are associated with decreased offspring IQ and modified brain structure. As numerous environmental chemicals disrupt thyroid hormone signalling, we questioned whether exposure to ubiquitous chemicals affects thyroid hormone responses during early neurogenesis. We established a mixture of 15 common chemicals at concentrations reported in human amniotic fluid. An in vivo larval reporter (GFP) assay served to determine integrated thyroid hormone transcriptional responses. Dose-dependent effects of short-term (72 h) exposure to single chemicals and the mixture were found. qPCR on dissected brains showed significant changes in thyroid hormone-related genes including receptors, deiodinases and neural differentiation markers. Further, exposure to mixture also modified neural proliferation as well as neuron and oligodendrocyte size. Finally, exposed tadpoles showed behavioural responses with dose-dependent reductions in mobility. In conclusion, exposure to a mixture of ubiquitous chemicals at concentrations found in human amniotic fluid affect thyroid hormone-dependent transcription, gene expression, brain development and behaviour in early embryogenesis. As thyroid hormone signalling is strongly conserved across vertebrates the results suggest that ubiquitous chemical mixtures could be exerting adverse effects on foetal human brain development.

    Next to nothing is known about nanoparticle and nanofiber trafficking at the feto-maternal interface in early human pregnancy. As the first trimester is thought to be crucial for the further placental and fetal development, it will be important to assess the possible risks of nanomaterial exposures during this period. There are some intriguing observations in nanotoxicology, however, indicating certain differences between classical toxicology and nanotoxicology. To understand nanomaterial-biokinetics and placental toxicity in early gestation, the special architecture, the hypoxic condition, the bilayer of villous trophoblast, the plugging of spiral arteries and the contribution of intrauterine glands to nutrition, as well as the delicate immunologic situation at the implantation site, will have to be considered. Unless nano-specific biokinetics are properly understood, it will be difficult to ensure identification of potential "nano-thalidomides" among all the newly engineered nanoparticles and fibers, based on the models available in reproductive toxicology.

    Context Postpartum depression (PPD) is common and has serious implications for the mother and her newborn. A possible link between placental corticotropin-releasing hormone (pCRH) and PPD incidence has been discussed, but there is a lack of empirical evidence. Objective To determine whether accelerated pCRH increases throughout pregnancy are associated with PPD symptoms. Design Pregnant women were recruited into this longitudinal cohort study. Blood samples were obtained at 15, 19, 25, 31 and 37 weeks gestational age (GA) for assessment of pCRH, cortisol and ACTH. Depressive symptoms were assessed with a standardized questionnaire at the last four pregnancy visits and postpartum. Setting Subjects were recruited from two Southern California Medical Centers, and visits were conducted in university research laboratories. Participants 100 adult women with a singleton pregnancy. Main Outcome Measure PPD symptoms were assessed 8.7 weeks (SD = 2.94 wks) after delivery with the Edinburgh Postnatal Depression Scale. Results Sixteen women developed PPD symptoms. At 25 weeks GA, pCRH was a strong predictor of PPD symptoms (R2 = .21, β = .46, p < .001), an effect that remained significant after controlling for prenatal depressive symptoms. No significant associations were found for cortisol and ACTH. Receiver Operating Characteristic curve analyses revealed that pCRH at 25 weeks GA is a useful diagnostic test (area under the curve = .78, p = .001). Sensitivity (.75) and specificity (.74) at the ideal cut-off point (56.86 pg/ml pCRH) were high. Growth curve analyses indicated that pCRH trajectories in women with PPD symptoms are significantly accelerated between 23 and 26 weeks GA. Conclusion There is a critical period in mid-pregnancy during which pCRH is a sensitive and specific early diagnostic test for PPD symptoms. If replicated, these results have implications for identification and treatment of pregnant women at risk of PPD. PMID:19188538

    Full Text Available Folate deficiency (FD during pregnancy can cause fetal intrauterine growth restriction in pigs, of which the skeletal dysplasia is a major manifestation. Factors influencing muscle development are very important in the formation of porcine meat quality trait. However, the effect of folate deficiency on skeletal muscle development and its molecular mechanisms are unknown. The objective of this study is to determine the effect of maternal folate deficiency on the skeletal muscle transcriptome of piglets from a reciprocal cross, in which full-sibling Landrace (LR and full-sibling Chinese local breed Laiwu (LW pigs were used for reciprocal cross matings, and sows were fed either a folate deficient or a normal diet during early-mid gestation. In addition, the difference in the responsiveness of the piglets to folate deficiency during early-mid pregnancy between reciprocal cross groups was investigated. Longissimus dorsi (LD muscle samples were collected from newborn piglets and a 4 × 44K Agilent porcine oligo microarray was used for transcriptome analysis of porcine LD muscle. The results showed that folate deficiency during early-mid pregnancy affected piglet body weight, LD muscle fiber number and content of intramuscular triglyceride. The microarray results indicated that 3154 genes were differentially expressed between folate deficient and normal piglets from the LR♂ × LW♀ cross, and 3885 differentially expressed genes (DEGs in the ones from the LW♂ × LR♀ cross. From functional analyses, sow folate deficiency affected almost all biological processes in the progeny. Lipid metabolism-related genes and associated metabolic pathways were regulated extensively by folate deficiency, especially in LR♂ × LW♀ cross piglets. Most of the genes that are regulated by folate deficiency in the LD muscle of piglets were different between LR♂ × LW♀ and LW♂ × LR♀ crosses, suggesting some epigenetic effects of FD exist in genes underlying

    To describe the histological changes of fetal adnexa throughout the physiological pregnancy, canine samples were obtained during natural delivery and caesarean section, as well as during ovariohysterectomy performed at any stage of undesired pregnancies (N=12). The first period of pregnancy (multiple samples collected at 10, 12, 14 days) was consistent with pre- and peri-implantation events, i.e. apposition and initial invasion steps into the endometrium. The second period (multiple samples collected at 18, 38, 40, 45 days) was related to the development of extra-embryonic structures, placenta establishment and labyrinth formation. At the end of this period the maximum morphological complexity of the endotheliochorial placenta was achieved, characterized by complete erosion of the endometrial epithelium and underlying interstitium with exposure of maternal capillaries to the chorial cells. The third period of gestation (multiple samples collected at 50, 53, 57, 60, 63 days) was characterized by enhancement either of placental and extra-embryonic tissues.

    Full Text Available We present a case of sonographic demonstration of quadruplet heterotopic pregnancy consisting of twin intrauterine (IU pregnancy and a twin adnexal pregnancy after ovulation induction (OI with clomiphene citrate (CC and timed intercourse (TI. Both heterotopic pregnancy and spontaneous twinning are frequent after OI, this combination although extremely rare must be kept in mind. The role of early transvaginal sonography and serum beta human chorionic gonadotrophin after missed periods helps in early diagnosis. It gives us an opportunity for medical management, saving the patient the agony of surgery along with loss of pregnancy. The management of heterotopic pregnancy is controversial. This patient did not have a viable IU pregnancy and both the sacs in the adnexa were small. Thus, we treated her successfully by medical management with systemic methotrexate, with regular follow-up. This patient successfully conceived after 6 months with OI and TI, with ovulation occurring from the same side of the previous ectopic. She had a viable IU gestation corresponding to 12 weeks.

    Full Text Available Abstract Background There are good opportunities in Sweden for health promotion targeting expectant parents and parents of young children, as almost all are reached by antenatal and child health care. In 2005, a multisectoral child health promotion programme (the Salut Programme was launched to further strengthen such efforts. Methods Between June and December 2010 twenty-four in-depth interviews were conducted separately with first-time mothers and fathers when their child had reached 18 months of age. The aim was to explore their experiences of health promotion and lifestyle change during pregnancy and early parenthood. Qualitative manifest and latent content analysis was applied. Results Parents reported undertaking lifestyle changes to secure the health of the fetus during pregnancy, and in early parenthood to create a health-promoting environment for the child. Both women and men portrayed themselves as highly receptive to health messages regarding the effect of their lifestyle on fetal health, and they frequently mentioned risks related to tobacco and alcohol, as well as toxins and infectious agents in specific foods. However, health promotion strategies in pregnancy and early parenthood did not seem to influence parents to make lifestyle change primarily to promote their own health; a healthy lifestyle was simply perceived as 'common knowledge'. Although trust in health care was generally high, both women and men described some resistance to what they saw as preaching, or very directive counselling about healthy living and the lack of a holistic approach from health care providers. They also reported insufficient engagement with fathers in antenatal care and child health care. Conclusion Perceptions about risks to the offspring's health appear to be the primary driving force for lifestyle change during pregnancy and early parenthood. However, as parents' motivation to prioritise their own health per se seems to be low during this period

    This prospective study evaluated whether serum glycodelin and insulin-like growth factor binding protein 1 (IGFBP-1) predict the likelihood of embryo implantation in recipients undergoing donor egg in vitro fertilization. We measured glycodelin and IGFBP-1 at 6 points from lining check to lutenizing hormone (LH) + 31. β-Human chorionic gonadotropin levels were first measured at LH + 17. The recipients were divided into those without embryo implantation (group 1, n = 6) and those with successful implantation (group 2, n = 30). Although this is a negative study in that neither glycodelin nor IGFBP-1 alone reflected endometrial (EM) receptivity, the glycodelin/IGFBP-1 ratio on the day of blastocyst transfer was higher in recipients who achieved pregnancy (P = .05). At LH + 17, glycodelin was higher (P = .04), and IGFBP-1 was lower (P = .004) in recipients who achieved pregnancy when compared to those who did not. These observations are likely due to EM changes induced by successful embryo implantation.

    Full Text Available Abstract Background The female reproductive tract is amongst the main routes for Human Immunodeficiency Virus (HIV transmission. Cervical mucus however is known to protect the female reproductive tract from bacterial invasion and fluid loss and regulates and facilitates sperm transport to the upper reproductive tract. The purpose of this study was to purify and characterize pregnancy plug mucins and determine their anti-HIV-1 activity in an HIV inhibition assay. Methods Pregnancy plug mucins were purified by caesium chloride density-gradient ultra-centrifugation and characterized by Western blotting analysis. The anti-HIV-1 activities of the crude pregnancy plug mucus and purified pregnancy plug mucins was determined by incubating them with HIV-1 prior to infection of the human T lymphoblastoid cell line (CEM SS cells. Results The pregnancy plug mucus had MUC1, MUC2, MUC5AC and MUC5B. The HIV inhibition assay revealed that while the purified pregnancy plug mucins inhibit HIV-1 activity by approximately 97.5%, the crude pregnancy plug mucus failed to inhibit HIV-1 activity. Conclusion Although it is not clear why the crude sample did not inhibit HIV-1 activity, it may be that the amount of mucins in the crude pregnancy plug mucus (which contains water, mucins, lipids, nucleic acids, lactoferrin, lysozyme, immunoglobulins and ions, is insufficient to cause viral inhibition or aggregation.

    Full Text Available Abstract Background Heat shock proteins (Hsps are a set of highly conserved proteins, Hsp105, has been suggested to play a role in reproduction. Methods Spatio-temporal expression of Hsp105 in rat uterus during peri-implantation period was examined by immunohistochemistry and Western blot, pseudopregnant uterus was used as control. Injection of antisense oligodeoxynucleotides to Hsp105 into pregnant rat uteri was carried out to look at effect of Hsp105 on embryo implantation. Results Expression of Hsp105 was mainly in the luminal epithelium on day 1 of pregnancy, and reached a peak level on day 5, whereas in stroma cells, adjacent to the implanting embryo, the strongest expression of Hsp105 was observed on day 6. The immunostaining profile in the uterus was consistent with that obtained by Western blot in the early pregnancy. In contrast, no obvious peak level of Hsp105 was observed in the uterus of pseudopregnant rat on day 5 or day 6. Furthermore, injection of antisense oligodeoxynucleotides to Hsp105 into the rat uterine horn on day 3 of pregnancy obviously suppressed the protein expression as expected and reduced number of the implanted embryos as compared with the control. Conclusion Temporal and spatial changes in Hsp105 expression in pregnant rat uterus may play a physiological role in regulating embryo implantation.

    The utility of transrectal ultrasonography was tested in a field setting to characterize the reproductive tract and detect early pregnancy (embryonic vesicles body, ovaries with follicles and corpora lutea) using a 5-10 MHz linear-array probe with a 70 cm-long extension. A single pregnancy was detected in 14 of 17 seals (82.4%) as a circular or guitar-pick shaped nonechogenic (black) vesicle with a clearly visible echogenic border within the lumen of the uterus. The stage of embryonic development (ostensibly the gestational age) varied markedly among individuals, ranging from a vesicle with no embryo proper to a large fetus with an ocular orbit, nose/mouth, limb buds, spinal column, umbilical cord, and prominent vasculature. Two of the pregnant seals were re-examined 3-6 days after the initial examination to obtain longitudinal growth rates. Images of one or both ovaries were obtained in nine and seven of the 19 examinations, respectively. Numerous ovarian follicles (3 to 12 mm diameter) were detected and animals typically had a single well-perfused corpus luteum (determined by Doppler color-flow) ipsilateral to the uterine horn containing the pregnancy. We conclude that real-time transrectal ultrasonography is an effective tool for characterizing reproductive events in phocids including ovarian dynamics, and for elucidating the nature of embryonic diapause.

    The case study is a 33-year-old white female with persistently elevated serum human chorionic gonadotropin (hCG) levels following methotrexate treatment and emergency surgery for ectopic pregnancy. At the time of the first methotrexate dose, the serum hCG concentration was 27,995 IU/L. The laboratory was consulted 3.5 months after the surgery, because serum hCG levels had stopped declining and had leveled off to around 80 to 90 IU/L but with negative urine pregnancy tests. Laboratory studies ruled out heterophile antibody interference and hook effect by multiple methods including analysis by different serum hCG assays, treatment with heterophile antibody blocking agents, and dilution studies. Three additional doses of methotrexate over six months were required for serum hCG concentrations to decline to undetectable levels. This case illustrates challenges that may arise with serum hCG measurements in management of ectopic pregnancies. Close collaboration between the laboratory and clinical service is key for optimal patient care.

  1. Selective Serotonin Reuptake Inhibitors in Human Pregnancy: To Treat or Not to Treat?

    Directory of Open Access Journals (Sweden)

    Orna Diav-Citrin

    2012-01-01

    Full Text Available Selective serotonin reuptake inhibitors (SSRIs are increasingly prescribed during pregnancy. The purpose of the present paper is to summarize and evaluate the current evidence for the risk/benefit analysis of SSRI use in human pregnancy. The literature has been inconsistent. Although most studies have not shown an increase in the overall risk of major malformations, several studies have suggested that SSRIs may be associated with a small increased risk for cardiovascular malformations. Others have noted associations between SSRIs and specific types of rare major malformations. In some studies, there appears to be a small increased risk for miscarriages, which may be associated with the underlying maternal condition. Neonatal effects have been described in up to 30% of neonates exposed to SSRIs late in pregnancy. Persistent pulmonary hypertension of the newborn has also been described with an absolute risk of <1%. The risk associated with treatment discontinuation, for example, higher frequency of relapse and increased risk of preterm delivery, should also be considered. The overall benefit of treatment seems to outweigh the potential risks.

    2009-09-01

    Full Text Available Abstract Background Apolipoprotein D (ApoD is a lipocalin involved in several processes including lipid transport, but its modulation during human pregnancy was never examined. Methods We investigated the changes in the levels of ApoD in the plasma of pregnant women at the two first trimesters of gestation and at delivery as well as in the placenta and in venous cord blood. These changes were studied in 151 women classified into 9 groups in relation to their prepregnancy body mass index (BMI and gestational weight gain (GWG. Results Plasma ApoD levels decrease significantly during normal uncomplicated pregnancy. ApoD is further decreased in women with excessive GWG and their newborns. In these women, the ApoD concentration was tightly associated with the lipid parameters. However, the similar ApoD levels in low cholesterol (LC and high cholesterol (HC women suggest that the plasma ApoD variation is not cholesterol dependant. A tight regulation of both placental ApoD transcription and protein content is most probably at the basis of the low circulating ApoD concentrations in women with excessive GWG. After delivery, the plasma ApoD concentrations depended on whether the mother was breast-feeding or not, lactation favoring a faster return to baseline values. Conclusion It is speculated that the decrease in plasma ApoD concentration during pregnancy is an adaptive response aimed at maintaining fetal lipid homeostasis. The exact mechanism of this adaptation is not known.

    Telephone follow-up with a self-performed low-sensitivity urine pregnancy (LSUP) test was introduced at the Royal Infirmary of Edinburgh, Scotland, as an alternative to routine ultrasonography for confirming successful abortion at 2 weeks following early medical abortion (ultrasound. A service evaluation was conducted of the first 8 months of telephone follow-up consisting of a review of the numbers choosing this method of follow-up, the proportion successfully contacted and the efficacy for detecting ongoing pregnancies. In the last 3 months of the study, women were surveyed about their satisfaction with this method of follow-up. Opting for telephone follow-up were 476 out of 619 women (77%). Four women (1%) attended the clinic before telephone follow-up because of pain or bleeding. A total of 410 (87%) of the remaining 472 women were successfully contacted by telephone. Sixty women (15%) screened 'positive', three of whom had ongoing pregnancies, and one woman falsely screened 'negative'. The sensitivity of the telephone follow-up was 75% [95% confidence interval (CI) 30.1-95.4], and specificity was 86% (95% CI 82.2-89). The negative predictive value was 99.7% (95% CI 98.4-99.9), and positive predictive value was 5% (95% CI 1.7-13.7). All women surveyed (n=75) would recommend telephone follow-up to a friend. A telephone follow-up and an LSUP test at 2 weeks are effective for detecting ongoing pregnancy, have good follow-up rates and are popular choices for women. Copyright © 2012 Elsevier Inc.

    Full Text Available The aim of this study was to analyze the specificity and dynamics of psychomotor development in children from triplet pregnancy. The studied group was composed of siblings from triple pregnancy (T1, T2, T3, including two girls and one boy. This longitudinal study comprised three stages: stage I – children aged 25 months, stage II – children aged 29 months, and stage III – children aged 38 months. At each stage, the psychomotor development of children was examined with the Third Edition of Bayley Scales of Infant and Toddler Development (BSID-III and subjectively by their mother. Additionally, medical and nursing documentation was analyzed. Individual psychomotor development of children from triple pregnancy is different with regards to various spheres, and has different rates and dynamics throughout consecutive years. Psychomotor development of children from triple pregnancies is determined by gender and postnatal clinical parameters, i.e. birth weight, head circumference, postnatal morbidity, and prematurity-related conditions.

    Little is known about the relationships between pregnancy cravings, maternal diet, and development of abnormal glucose tolerance. We examined relationships of pregnancy cravings with dietary intake and risk of developing isolated hyperglycemia (IH), impaired glucose tolerance (IGT), or gestational diabetes (GDM) later in pregnancy. Among 2,022 mothers in Project Viva, a prospective birth cohort recruited from medical practices in eastern Massachusetts between 1999 and 2002, we assessed type of pregnancy craving based on self-report at mean gestation of 10.9 weeks. The outcomes were cross-sectional dietary intake from a food frequency questionnaire and incident IH, IGT, or GDM determined by glucose tolerance screening at 26 to 28 weeks. We used linear regression to analyze the cross-sectional relationships between pregnancy cravings and dietary intake and multinomial logistic regression to analyze the prospective relationships among pregnancy cravings and development of IH, IGT, or GDM. During the first trimester, 443 (22%) women craved sweets, 225 (11%) craved salty foods, 261 (13%) craved savory foods, and 100 (4.9%) craved starchy foods. Sweet cravings were associated with increased intake of sucrose (1.9 g/day; 95% CI 0.1 to 3.7), total fat (1.5 g/day; 95% CI 0.1 to 2.9), and saturated fat (0.8 g/day; 95% CI 0.2 to 1.4); salty cravings were associated with increased fiber (0.7 servings/day; 95% CI -0.1 to 1.6); savory cravings were associated with increased n-3 fatty acids (0.10 g/day; 95% CI 0.02 to 0.17); and starchy cravings were associated with increased carbohydrates (8.0 g/day; 95% CI 0.3 to 15.7) and decreased total fat (-2.6 g/day; 95% CI -5.2 to -0.1). Salty cravings were associated with lower risk of GDM (adjusted odds ratio 0.34, 95% CI 0.12-0.97). New cravings in the first trimester of pregnancy were associated with dietary intake. Craving salty foods may predict reduced risk of developing GDM, whereas craving sweet food does not appear to alter one

    Background Some studies suggested that human papillomavirus (HPV) infection could reduce the clinical pregnancy rate and double the spontaneous abortion rate compared with non-infected women after in-vitro fertilization and embryo transfer (IVF-ET).But some other studies showed there was no difference between HPV infected and non-infected groups of ART outcomes.The role of HPV infection in infertile women undergoing IVF treatments has been a controversial issue which this article attempts to investigate.Methods This is a retrospective analysis of 3880 infertile women undergoing IVF treatment at Peking University Third hospital reproductive medical center in 2008.Patients with abnormal thin-layer preparation cytologic test (TCT) results who underwent fresh cycle embryo transfer were divided into an HPV positive group (n=56) and an HPV negative group (n=56).The clinical parameters were compared (using Student's t-test and chi-squared test).Univariate and multivariate analyses were taken to see if HPV infection affects the clinical pregnancy rate.Results Of the 3880 cases 157 had TCT abnormality (4.0%).Of the 149 patients who had HPVtest results,112 women (81.2%) received a fresh cycle embryo transfer.Each group had 56 cases.The patients were of similar age and BMI,basic hormone levels,and infertile factors were similar.The gonadotropin use,oocyte retrieval number,clinical pregnancy rate,abortion rate and newborn condition were all similar between groups.Analyses showed neither HPV infection nor HPV hybrid capture (HC) Ⅱ results affected clinical pregnancy rate after IVF treatments,but the FSH level did.Conclusion HPV positivity did not appear to impact assisted reproductive technology (ART) success."Extensive treatment" for HPV before IVF was not recommended because treatment time will increase age and reduce ovarian function,which will lead to inferior IVF outcomes.

    Full Text Available Abstract Background The role for endometrial secretion of cytokines during the establishment of pregnancy in a number of mammals is well established. The current study determined endometrial expression of caspase 1 (CASP1 and interleukin-18 (IL18 during the estrous cycle and early pregnancy, and following early estrogen administration, which induces conceptus loss during early development in pigs. Methods Gilts were hysterectomized on either D 0, 5, 10, 12, 15 and 18 of the estrous cycle, or D 10, 12, 15 or 18 of pregnancy. The abundance of endometrial CASP1 mRNA was unaffected by day of the estrous cycle, however there was a 6 and 10-fold increase in expression on D 15 and 18 of pregnancy. Endometrial expression of IL18 mRNA increased 5-fold between D 10 to 18 in cyclic and pregnant gilts. Total recoverable IL18 in uterine flushings was greater in pregnant compared to cyclic gilts on D 15 and 18. In the second experiment, mated gilts were treated with either corn oil (CO or estrogen (E on D 9 and 10 and hysterectomized on either D 10, 12, 13, 15 or 17 of pregnancy. The current study localizes the presence of CASP1 to the epithelial layer of the endometrium for the first time. Further, a day × treatment interaction was detected for endometrial CASP1 mRNA and protein abundance as E stimulated an earlier increase on D 13 compared to CO gilts. Although IL18 mRNA expression remained unaltered from the E treatment, protein abundance was significantly attenuated on D 15 and 18 in response to E treatment. Conclusions Endometrial expression of CASP1 and IL18 is associated with establishment of pregnancy in pigs. Alteration of CASP1 and IL18 following premature exposure of the uterus to estrogen during early pregnancy may contribute to conceptus loss between Days 15 to 18 of pregnancy.

    Objective To determine the concentrations of cholesterol sulfate (CS) in human sera and placental villi during the course of pregnancy. And to analyze its inhibitory activity on thrombin and further characterize the functional significance of CS. Methods The concentrations of CS were determined by thin-layer chromatography (TLC) on 60 cases of normal pregnant women and 30 cases of normal placental villi. The effect of CS in human sera on the activity of thrombin was analyzed. Results The concentrations of CS in human sera gradually increased from the first to third trimester of gestation with a correlation coefficient of 0.69, and a correlation between the concentration of CS and weeks of gestation (P <0.01 ). CS was also contained in the placental villi, and its concentrations at the second and third trimester of gestations were 4. 7 and 6. 2-fold of that at the first trimester of gestation. CS inhibited the activity of thrombin. Conclusion Placental CS is one of the sources of CS in the serum, probably by shedding. From the observation that CS inhibited the activity of thrombin, the increased expression of CS may play an important role in the regulation of blood coagulation during the course of pregnancy.

    The effects of ritodrine, administered by intravenous, intramuscular or per os routes, upon plasma levels of unconjugated estriol, estradiol, progesterone and human placental lactogen (HPL) were investigated in 24 third-trimester pregnancies. Ritodrine administered at a constant rate of 200 micrograms/min for 3 h, injected intramuscularly 8 x 10 mg/day for 5 days or given orally in doses of 6 x 20 mg/day for 10 days resulted in a significant decrease in the steroid hormone concentration and a significant elevation of HPL levels.

    Maternal thyroid hormone insufficiency during pregnancy can affect children's cognitive development. Nevertheless, the behavioral outcomes of children exposed prenatally to mild thyroid hormone insufficiency are understudied. To examine whether exposure to maternal mild thyroid hormone insufficiency in early pregnancy was related to symptoms of attention-deficit/hyperactivity disorder (ADHD) in children at 8 years of age. The study was embedded within the Generation R, a population-based birth cohort in the Netherlands. Children in the Generation R Study are followed up from birth (April 1, 2002, through January 31, 2006) until young adulthood. Of the 4997 eligible mother-child pairs with data on maternal thyroid levels (excluding twins), 3873 pairs of children and caregivers (77.5%) visited the Generation R research center for in-depth assessments and were included in the main analyses. Data collection in Generation R started December 1, 2001 (enrollment of pregnant women), and is ongoing. For this study, we used the data that were collected until January 1, 2014. Data analyses started on January 31 and finished June 30, 2014. Maternal hypothyroxinemia, characterized by low levels of free thyroxine coexisting with reference thyrotropin levels, and children's symptoms of ADHD. Maternal thyroid hormone levels (thyrotropin, free thyroxine, thyroid peroxidase antibodies) were measured at a mean (SD) of 13.6 (1.9) weeks of gestation. Children's ADHD symptoms were assessed at 8 years of age using the Conners' Parent Rating Scale-Revised Short Form; higher scores indicate more ADHD symptoms (possible range, 0-36). Maternal hypothyroxinemia (n = 127) in early pregnancy was associated with higher scores for ADHD symptoms in children at 8 years of age after adjustments for child and maternal factors (ie, sex, ethnicity, maternal age, maternal educational level, and income) (increase in ADHD scores, 7% [95% CI, 0.3%-15%]). The results remained essentially unchanged when

    Cytokines within the uterus are critical in the maternal-fetal immune regulation. Immunosuppressive cytokine IL-35 was recently discovered inhibitory cytokine, which were pivotal in the establishment of immune tolerance against self-antigens and antigens encountered in foreign implantation. In order to analyze the role of IL-35 in maternal-fetal immune tolerance, the expression patterns of IL-35 in mouse endometrium were studied during early pregnancy by immunohistochemistry, ELISA and quantitative real-time PCR. As results, we found that IL-35 positive cells in the uterus showed significant distribution difference after fetal implantation, which mainly distributed in luminal epithelium and glandular epithelium of mouse uterus from gestational day 1 to 2, and glandular epithelium and stroma from gestational day 4 to 7. The number of positive cells, immunoreactive scores, protein and mRNA expression of IL-35 showed firstly increased and then decreased with the increase of pregnancy day. The largest contents of IL-35 in the uterus were detected on gestational day 4. Compared with non-pregnant mice, pregnant mice showed the significantly increased mRNA expression of Ebi3 (Epstein-Barr virus-induced gene 3, IL-35 subunit) in the endometrium on gestational day 2 and the highest level of expression on gestational day 4. The mRNA expression of p35 (IL-35 subunit) was significantly lower than that of Ebi3 gene and showed the inconsistent change from gestational day 5 to 7. However, the significant correlation existed between the immunohistochemical expression, contents and mRNA expression of IL-35. These results indicated that IL-35 contributed to the establishment and maintenance of maternal-fetal tolerance during early pregnancy.

METHODS AND RESULTS: Of 266 healthy, singleton pregnancies, 182 women were nonsmokers, 43 were smokers, and 41 stopped smoking early in pregnancy. eNOS activity and concentration were quantified...... were similar for nonsmokers, smokers, and ex-smokers. CONCLUSIONS: The findings suggest that maternal smoking reduces eNOS activity in the fetal vascular bed, contributing to retarded fetal growth caused by the reduction of vasodilatory capacity, and suggest that smoking cessation early in pregnancy...... in endothelial cells of the fetal vessels. Cotinine, lipid profiles, estradiol, l-arginine, and dimethylarginines that may affect NO production were determined in maternal and fetal blood. Serum cotinine verified self-reported smoking. Newborns of smokers had a lower weight (P

    The INMA (INfancia y Medio Ambiente [Spanish for Environment and Childhood]) project is a cooperative research network. This project aims to study the effects of environment and diet on fetal and early childhood development. This article aims to present the air pollutant exposure protocol during pregnancy and fetal and early childhood development of the INMA project. The information to assess air pollutant exposure during pregnancy is based on outdoor measurement of air pollutants (nitrogen dioxide [NO2], volatile organic compounds [VOC], ozone, particulate matter [PM10, PM2,5 ] and of their composition [polycyclic aromatic hydrocarbons]); measurement of indoor and personal exposure (VOC and NO2); urinary measurement of a biological marker of hydrocarbon exposure (1-hydroxypyrene); and data gathered by questionnaires and geographic information systems. These data allow individual air pollutant exposure indexes to be developed, which can then be used to analyze the possible effects of exposure on fetal development and child health. This protocol and the type of study allow an approximation to individual air pollutant exposure to be obtained. Finally, the large number of participants (N = 4,000), as well as their geographic and social diversity, increases the study's potential.

    The health of the new-born is largely a function of the mother's nutritional, general and reproductive health status. Therefore, pregnancy is considered as a critical window in child’s growth and development. Several characteristics of a woman prior or in early pregnancy, as well as external, environmental factors affect pregnancy outcomes. External factors account for 30% of the pregnancy outcome and infant's birth weight, and mother’s diet during pregnancy is one of the most important ones....

    We examined the impact of human pregnancy on breathlessness intensity at matched levels of ventilation (V˙E) during isoxic hyperoxic CO₂ rebreathing and incremental cycle exercise tests in 21 healthy women in the third trimester (TM₃) and again ∼5 months post-partum (PP). Pregnancy had no significant (P > 0.05) effect on the slope or threshold of the breathlessness intensity-V˙E relationship during both exercise and rebreathing. By contrast, the slope of the breathlessness intensity-V˙E relationship was significantly higher, while the threshold of this relationship was consistently lower during rebreathing vs. exercise (both P pregnancy status (P > 0.05). As a result, breathlessness intensity was markedly higher at any given V˙E (e.g., by ∼4 Borg units at 40 L/min) during rebreathing vs. exercise, regardless of pregnancy status. Inter-subject variation in breathlessness intensity-V˙E slopes during exercise was not associated with inter-subject variation in breathlessness intensity-V˙E slopes during rebreathing or with increased central chemoreflex responsiveness during pregnancy (both P > 0.05). In conclusion, the intensity of perceived breathlessness for a given V˙E depends, at least in part, on the nature and source of increased central respiratory motor command output, independent of pregnancy status; and pregnancy-induced increases in activity-related breathlessness cannot be easily explained by increased central chemoreflex responsiveness.

  5. Thyroid disease and pregnancy.

    Thyroid disease is common in younger women and may be a factor in reproductive dysfunction. This probably only applies to severe cases of hyper- or hypothyroidism. Once adequately treated, neither of these disorders significantly impacts on fertility. The key is to recognize and to treat thyroid disorders in the reproductive-age woman before conception. Thyroxine therapy and even antithyroid drug therapy should be continued during pregnancy as necessary. Pregnancy is a euthyroid state that is normally maintained by complex changes in thyroid physiology. The fetal and neonatal hypothalamic-pituitary-thyroid system develops independently, but it may be influenced by thyroid disease in the mother. Early pregnancy is characterized by an increase in maternal T4 secretion stimulated by hCG and an increase in TBG, resulting in the elevated total serum T4 in pregnancy. The debate continues as to whether maternal T4 is important in early or late fetal brain development. If so, the physiologic changes in thyroid hormone secretion and transport in early pregnancy would help to ensure that a sufficient amount of thyroid hormone was available. There is new evidence in human subjects that substantial maternal T4 can cross the placenta during pregnancy, and this may be particularly important when fetal thyroid function is compromised as a result of congenital hypothyroidism. Maternal and fetal/neonatal outcomes in pregnancy are adversely affected if severe hypothyroidism is undiagnosed or inadequately treated. Thyroid function tests should be obtained during gestation in women taking T4 and appropriate dose adjustments should be made for TSH levels outside a normal range. The TSH-receptor blocking antibodies from the mother are a recognized cause of congenital hypothyroidism in the fetus and neonate that can be permanent or transient. If neonatal hypothyroidism is detected through neonatal screening programs, and prompt and adequate T4 replacement therapy is instituted as soon as

    During pregnancy and postpartum rats experience a wide variety of behavioural changes. Since the somatostatinergic system has been implicated in the control of some of these changes, the present study examined somatostatin (SS) content and specific binding in the frontoparietal cortex and hippocampus of non-pregnant, pregnant (17 to 18 days), parturition and postpartum (10 and 30 days) rats as well as in ovariectomized rats which were or were not treated with estradiol valerianate. The content of somatostatin-like immunoreactivity (SSLI) was increased at 17 days of pregnancy in frontoparietal cortex and decreased at parturition and 10 days postpartum in that region and the hippocampus under study when compared with SSLI levels in non-pregnant rats. At 30 days postpartum the SSLI content returned to non-pregnant values in both brain regions. Scatchard analysis showed that the decrease in [125I]Tyr11-SS binding observed at 17 days of pregnancy in the frontoparietal cortex was due to the decrease in the number of SS receptors. In contrast, on the day of delivery the number of SS receptors in the same brain region increased. The affinity of the SS receptors was consistently unchanged in pregnant and non-pregnant rats in both regions. At 10 days postpartum the value of specific binding of the tracer to SS receptors in the frontoparietal cortex w
