    Aim: Aquaporin 8 (AQP8) is expressed within the female reproductive system but its physiological function reminds to be elucidated.This study investigates the role of AQP8 during pregnancy using AQP8-knockout (AQP8-KO) mice.Methods: Homozygous AQP8-KO mice were mated, and the conception rate was recorded. AQP8-KO pregnant mice or their offspring were divided into 5 subgroups according to fetal gestational day (7, 13, 16, 18 GD) and newborn. Wild type C57 pregnant mice served as the control group. The number of pregnant mice, total embryos and atrophic embryos, as well as fetal weight, placental weight and placental area were recorded for each subgroup. The amount of amniotic fluid in each sac at 13, 16, and 18 GD was calculated. Statistical significance was determined by analysis of variance of factorial design and chi-square tests.Results: Conception rates did not differ significantly between AQP8-KO and wild type mice. AQP8-KO pregnant mice had a significantly higher number of embryos compared to wild type controls. Fetal/neonatal weight was also significantly greater in the AQP8-KO group compared to age-matched wild type controls. The amount of amniotic fluid was greater in AQP8-KO pregnant mice than wild type controis, although the FM/AFA (fetal weight/amniotic fluid amount) did not differ. While AQP8-KO placental weight was significantly larger than wild type controls, there was no evidence of placental pathology in either group.Conclusion: The results suggest that AQP8 deficiency plays an important role in pregnancy outcome.

The increased usage of AgNPs leads to a potential hazard to human health. However, the potential effects of AgNPs on animal models are not clear. This study was designed to investigate the potential impact of AgNPs on pregnant mice.Methods: The synthesis of AgNPs was performed using culture extracts of Bacillus cereus. The synthesized AgNPs were characterized by X-ray diffraction, Fourier transform infrared spectroscopy, and transmission electron microscopy. AgNPs were administrated into pregnant mice via intravenous infusion at 1.0 mg/kg doses at 6.5 days postcoitum (dpc. At 13.5, 15.5, and 17.5 dpc, the pregnant mice were euthanized, and the embryo and placenta were isolated. The meiotic status of oocytes was evaluated. DNA methylation studies were performed, and aberrant imprinting disrupted fetal, placental, and postnatal development. Quantitative real-time polymerase chain reaction analysis and Western blot were used to analyze various gene expressions.Results: The synthesized AgNPs were uniformly distributed and were spherical in shape with an average size of 8 nm. AgNPs exposure increased the meiotic progression of female germ cells in the fetal mouse ovaries, and maternal AgNP exposure significantly disrupted imprinted gene expression in 15.5 dpc embryos and placentas, such as Ascl2, Snrpn, Kcnq1ot1, Peg3, Zac1, H19, Igf2r, and Igf2; DNA methylation studies revealed that AgNPs exposure significantly altered the methylation levels of

    Congenital toxoplasmosis is one cause of abortion. Infection can disrupt ovarian cycles and because toxoplasmosis is an infectious disease may have a similar effect on the ovaries. The purpose of this study was to investigate the pathological changes in the ovaries due to toxoplasmosis. Tachyzoites of Toxoplasma gondii were harvested from peritoneal fluid of mice, experimentally infected. Two females and one male mouse were housed per cage for mating in the overnight. The pregnant mice were divided into experimental and control groups. Experimental group were infected by parasite but the control group received the normal saline. The experimental and control mice were euthanized. Ovaries and uterine horns of animals were removed and prepared for light microscopy. Ovaries of infected pregnant mice presented gross morphological differences compared to the control groups. In ovaries of experimental groups, changes of corpus luteum were observed. The comparison of experimental and control groups revealed that the number of primary follicles, secondary follicle, atretic primary follicles and atretic secondary follicles had significant differences (P≤0.001). Toxoplasma gondii alters ovarian follicular growth and development in mice. In addition, it alters number of different phases of follicles and corpus luteum in ovaries of mice.

    Sugar expressions were examined on the epithelium of both the middle portion of the vagina and the vaginal portion of the cervical canal (CC) in pregnant mice to understand the pathogenesis of bacterial infection in the female reproductive organ by using a panel of lectins. As a result, N-acetylglucosamine was positive before pregnant day (P) 7 but negative after P10 and at diestrus on both the vagina and the CC. In addition, some differences in sugar expressions were seen between them. These results suggest that sugar expressions on the mucosal surface would change not only site-specifically but also time-dependently, and these sugar differences indicate the possibility of the alteration of the settled bacterial species on the vaginal mucosa in pregnancy.

    The effect of beryllium (Be) compounds on porphyrins was investigated in pregnant mice. The blood protoporphyrin (Proto) and zinc protoporphyrin (Zn Proto) concentrations were increased in pregnancy. Regardless of pregnancy or nonpregnancy, the Proto concentration was decreased after Be injection. Delta-aminolevulinic acid dehydratase (ALA-D) and porphobilinogen deaminase (PBG-D) activities in blood were significantly elevated in the pregnant untreated (Con-pregnant) group, compared to the nonpregnant mice untreated (Con-nonpregnant) and nonpregnant mice treated with Be (Be-nonpregnant) groups. The blood ALA-D activity of the pregnant mice treated with Be (Be-pregnant group) tended to decrease, compared to Con-pregnant group. The blood PBG-D activity in the Be-pregnant group was significantly lower compared with that of the Con-pregnant group. The ALA-D and PBG-D activities in the spleen were also significantly elevated in the Con-pregnant group, compared to nonpregnant groups. However, it was noted that these values in the Be-pregnant group were almost the same as that of the Con-nonpregnant group and were significantly lower than that in the Con-pregnant group. The elevation of ALA-D and PBG-D activities in the blood and spleen, which play a role in the hematopoietic function of mice, was observed in the Con-pregnant mice compared to the nonpregnant mice. However, the phenomenon was not observed in the Be-pregnant mice, it suggesting that Be suppressed the pregnancy-induced increase in hematopoietic function.

    Full Text Available Introduction. Usually, infusion of intermittent doses of succinylcholin is used for relaxation of muscles in the preeclamptic pregnant women treated with magnesium sulfate during cesarian. section This drug has complications such as hyperkalemia, phase 11block, etc. On the other hand non depolarizing muscle relaxant in these patients should be used only in the presence of nerve stimulator and with careful titration. Methods. Duration of clinical action of a medium acting non depolarizing muscle relaxant "atracurium" with succinylcolin's infusion was studied in 86 preeclamptic pregnant women who received therapeutic doses of magnesium sulfate. Findings. Magnesium sulfate did not prolong clinical action of atracurium. Conclusion. Based on this study it can be concluded that administration of atracurium in the pregnant women who received therapeutic dose of magnesium sulfate in the absence of peripheral nerve stimulator is not contraindicated.

    Full Text Available Introduction: In traditional medicine, saffron is used as a drug for treating many diseases. However there are many documents and evidences concerning its abortive and teratogenic effect especially in high doses. Aim: This study was conducted to evaluate the effect of saffron decoction consumption on pregnant mice and their offspring. Methods: In this study, 20 female mice after breeding and observation of vaginal plaque, randomly and equally divided into two groups. During pregnancy, animals were housed under the same environmental and nutritional condition while the test group received 0.5% saffron decoction as their drinks instead of tape water for control group. The pregnant mice were weighted during pregnancy and after delivery. Following the parturition, the number of live kids, their weight and sex and any pretended obvious abnormality were assigned. Results: The duration of pregnancy period and the number of live kids in test group were significantly less than control group while the mean infant’s weight in test group was more than control group. There was obvious one-eye blindness in 4 kids from saffron consumed group. In the case of mother's weight and sex ratio of live kids there was no significant difference between the two groups. Conclusion: This study indicated that saffron has a specific teratogenic effect on visual system and causes preterm labor and reduces the number of live infants which may be due to its abortive effect.

    Iron deficiency is the most common nutritional disorder. Children and pregnant women are at highest risk for developing iron deficiency because of their increased iron requirements. Iron-deficiency anemia during pregnancy is associated with adverse effects on fetal development, including low birth weight, growth retardation, hypertension, intrauterine fetal death, neurologic impairment, and premature birth. We hypothesized that pregnant mice fed an iron-deficient diet would have a similar outcome regarding fetal growth to that of humans. To this end, we randomly assigned female C57BL/6 mice to consume 1 of 4 diets (high-iron–low-bioavailability, high-iron–high-bioavailability, iron-replete, and iron-deficient) for 4 wk before breeding, followed by euthanasia on day 17 to 18 of gestation. Compared with all other groups, dams fed the high-iron–high-bioavailability diet had significantly higher liver iron. Hct and Hgb levels in dams fed the iron-deficient diet were decreased by at least 2.5 g/dL as compared with those of all other groups. In addition, the percentage of viable pups among dams fed the iron-deficient diet was lower than that of all other groups. Finally, compared with all other groups, fetuses from dams fed the iron-deficient diet had lower fetal brain iron levels, shorter crown–rump lengths, and lower weights. In summary, mice fed an iron-deficient diet had similar hematologic values and fetal outcomes as those of iron-deficient humans, making this a useful model for studying iron-deficiency anemia during pregnancy.

    Full Text Available The results of research conducted in the canton of San Ramón, Costa Rica are presented, with 2012 data provided by the Local Committee on Maternal and Infant Mortality Review ( COLAMMI . The goal was to identifysources of support received by pregnant women, during pregnancy, after learning that the fetus had, malformations incompatible with life outside the womb, this support is provided in the process of mourning and sought to know the impact of that support with regard to mental health. From a qualitative approach the retrospective case study methodology was developed. The population was composed of three pregnant women who participated voluntarily and informed, the loss occurred between 3 months and a year prior to the study. Interview technique and review of the reports prepared by the COLAMMI was applied. The results indicate thatinterventions received by the first level of care are scarce and very late. It is concluded that the support provided by health personnel in the third level of health helped the pregnant to receive information about the grieving process and take more favorably decision. In this case, the intervention of first level of care was delayed and was difficult to access.

    Early and consistent intervention with pregnant smokers can reduce the incidence of adverse pregnancy outcomes associated with smoking during pregnancy. A survey of 470 pregnant women was conducted to establish the care they received in relation to smoking whilst attending routine public antenatal appointments. The overall prevalence of smoking was 23.5%. Age, level of education and nationality were associated with smoking status with younger, less educated Irish women being most likely to smoke. Women attending for their first visit were much more likely to be asked about their smoking status 71 (85.5) versus 68 (17.8) and advised to quit if they were smokers 11 (73.3) versus 11 (15.7). None of the women were offered specific assistance to help them stop smoking or had a follow-up appointment arranged specifically to do with smoking. 167 women (35.6) were exposed to passive smoking in their own homes.

    Microvesicles including exosomes and microparticles, participate in the placental-maternal crosstalk in normal pregnancies and gestational vascular complications (GVC). Low molecular weight heparin (LMWH) is known to reduce the risk of placenta-mediated pregnancy complications. This study was aimed to characterize microvesicles of pregnant women receiving LMWH and explore microvesicle involvement in trophoblast and endothelial cell function. Microvesicles were isolated from blood samples obtained from non-pregnant women, healthy pregnant women (HP) and pregnant woman treated with LMWH. Microvesicle protein contents were assessed by protein array and ELISA. Microvesicle effects on early stage trophoblasts, term trophoblasts and endothelial cell migration, angiogenesis and apoptosis were evaluated. Microvesicles derived from the group treated with LMWH contained higher levels of several proangiogenic proteins compared to those of HP women. Exposure of endothelial cells to circulating microvesicles derived from HP and LMWH treated groups induced significantly higher cell migration and branch tube formation compared to untreated cells. The effect of microvesicles from HP- and LMWH groups on early-stage trophoblast migration was similar. Microvesicles derived from these two study groups significantly decreased early-stage trophoblast apoptosis, while microvesicles derived from the HP-group (but not from the LMWH-group) significantly increased the term trophoblast apoptosis (TUNEL assay) compared to untreated cells. Therapy with LMWH affects patients' microvesicle content, leading to normalization of invasion, angiogenesis activity and survival of endothelial and trophoblast cells in vitro. The effects of LMWH on microvesicles may point to an additional mechanism of heparin action in high-risk pregnancy. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Full Text Available Background Given that family health is tied to women health, illness, or death of a woman has an adverse effect on the health of her child, family, and community; awareness of women’s preferences in receiving health information can help to improve and modify the methods of informing and providing appropriate services to them, and also makes pregnant women training more efficient and more effective. Objectives The aim of this study is to prioritize the preferences of women before and during pregnancy on receiving health information. Patients and Methods This descriptive study was performed on pregnant women who had referred to health care centers affiliated to Semnan University of Medical Sciences, Iran in 2014. An anonymous self-administered questionnaire was developed. Results The results showed that 17.5% (n = 35 of the participants reported their information needs about physical health to become pregnant, 36% (n = 72 psychological readiness for pregnancy and 57.5% (n = 115 domestic violence and its impact on the health of the mother and fetus. Number of previous delivery had a negative and significant relationship with the pregnant women’s preferences (B = - 1.31, P < 0.001. Conclusions It is concluded that the most of pregnant women are oblivious to their health for getting pregnant and some of them experience symptoms of mental disorders in reproductive age. The findings show that domestic violence is a hidden and persistent epidemic among the pregnant women. Women, who had more previous delivery, needed this information less.

    Concern about the possible adverse effects of radiofrequency (RF)-field exposure on public health has increased because of the extensive use of wireless mobile phones and other telecommunication devices in daily life. The murine fetus is a very sensitive indicator of the effects of stress or stimuli in the environment. Therefore, we investigated the teratogenic effects of multi-signal radiofrequency electromagnetic fields (RF EMFs) on mouse fetuses. Pregnant mice were simultaneously exposed to two types of RF signals, single code division multiple access (CDMA) and wideband code division multiple access (WCDMA). Mice received two 45-min RF-field exposures, separated by a 15-min interval, daily throughout the entire gestation period. The whole-body average specific absorption rate (SAR) of CDMA or WCDMA was 2.0 W/kg. The animals were killed humanely on the 18th day of gestation and fetuses were examined for mortality, growth retardation, changes in head size and other morphological abnormalities. From the results, we report for the first time that simultaneous experimental exposure to CDMA and WCDMA RF EMFs did not cause any observable adverse effects on mouse fetuses.

    To examine prenatal dental care needs, utilization and oral health counseling among Maryland women who delivered a live infant during 2001-2003 and identify the factors associated with having a dental visit and having an unmet dental need during pregnancy. Pregnancy Risk Assessment Monitoring System is an ongoing population based surveillance system that collects information of women's attitudes and experiences before, during, and shortly after pregnancy. Logistic regression was used to model dental visits and unmet dental need using predictor variables for Maryland 2001-2003 births. Less than half of all women reported having a dental visit and receiving oral health advice during pregnancy. Twenty-five percent of women reported a need for dental care, of which 33 % did not receive dental care despite their perceived need. Multivariate modeling revealed that racial minorities, women who were not married and those with annual income dental visit. Women who were not married, had low annual income, were older than 40 years of age, had an unintended pregnancy and received prenatal care later than desired were most likely to have an unmet dental need during pregnancy. Despite reported needs and existing recommendations to include oral health as a component of prenatal care, less than half of pregnant women have a dental visit during their pregnancy. One-third of women with a dental problem did not have a dental visit highlighting the unmet need for dental care during pregnancy.

    Sevoflurane is widely used in non-obstetric surgeries of pregnant women, but its influences on fetal brain are still not fully known. We set out to assess the effects of multiple maternal sevoflurane exposure on neurogenesis and cognitive dysfunction in fetus and offspring. Pregnant mice (gestational day 15.5) and cultured mouse neural stem cells (NSCs) received daily sevoflurane exposure (2.5%×2h and 4.1%×2h respectively) for three consecutive days. Cognitive function of the offspring was determined with the Morris water maze. The expression of Ccnd1 and Pax6 in fetal brains and NSCs were analyzed by immunofluorescence, Western blot and qPCR. The neurogenesis was evaluated by BrdU staining. Results showed that multiple sevoflurane exposure in pregnant mice caused the decrease of Pax6 and Ccnd1 expression, the inhibition of NSCs proliferation and fetal hippocampus neurogenesis, which may contribute to the impaired learning and memory in offspring at P28. Moreover, lithium mitigated the sevoflurane-induced reduction in Pax6, Ccnd1 and neurogenesis. All these results suggest that multiple sevoflurane exposure may induce detrimental effects in the developing brains of fetus and offspring by the depression of neurogenesis through Pax6 pathway.

    Household air pollution (HAP) resulting from the use of solid cooking fuels is a leading contributor to the burden of disease in India. Advanced combustion cookstoves that reduce emissions from biomass fuels have been considered potential interventions to reduce this burden. Relatively little effort has been directed, however, to assessing the concentration and exposure changes associated with the introduction of such devices in households. The aim of this study was to describe HAP exposure patterns in pregnant women receiving a forced-draft advanced combustion cookstove (Philips model HD 4012) in the SOMAARTH Demographic Development & Environmental Surveillance Site (DDESS) Palwal District, Haryana, India. The monitoring was performed as part of a feasibility study to inform a potential large-scale HAP intervention (Newborn Stove trial) directed at pregnant women and newborns. This was a paired comparison exercise study with measurements of 24-hour personal exposures and kitchen area concentrations of carbon monoxide (CO) and particulate matter less than 2.5 μm in aerodynamic diameter (PM2.5), before and after the cookstove intervention. Women (N = 65) were recruited from 4 villages of SOMAARTH DDESS. Measurements were performed between December 2011 and March 2013. Ambient measurements of PM2.5 were also performed throughout the study period. Measurements showed modest improvements in 24-hour average concentrations and exposures for PM2.5 and CO (ranging from 16% to 57%) with the use of the new stoves. Only those for CO showed statistically significant reductions. Results from the present study did not support the widespread use of this type of stove in this population as a means to reliably provide health-relevant reductions in HAP exposures for pregnant women compared with open biomass cookstoves. The feasibility assessment identified multiple factors related to user requirements and scale of adoption within communities that affect the field efficacy of

    Bovine genital tritrichomonosis is caused by the protozoon Tritrichomonas foetus and leads to embryonic death and abortion. The complexity of handling bovine experimental systems has led to the development of alternative models. The infection has been reproduced in pregnant BALB/c mice. In the pathogenesis of the disease, adhesion of the protozoon to host cell surface glycoproteins is important. Labelling with soya bean agglutinin (SBA) and peanut agglutinin (PNA) lectins increases in the luminal and glandular uterine epithelium of non-pregnant infected mice. The aim of the present study was to determine whether these changes also occur in pregnant infected BALB/c mice. Female BALB/c mice were inoculated intravaginally with T. foetus and, 15 ± 3 days post infection, were paired with males overnight. Infected and control mice were sacrificed 6, 8 and 10 days later. Samples of uterus were labelled with a panel of biotinylated lectins. Infected mice showed increased binding of PNA and SBA. There was also increased binding of concanavalin (Con-A) by luminal epithelium and Ricinus communis agglutinin (RCA-1) by glandular epithelium at day 6 post coitum. These changes may be due to the production of enzymes by T. foetus, which could act to enhance adhesion and colonization and thus favour infection.

    Oxytocin (OT) is the strongest uterotonic substance and has been used widely to induce labor. The physiological importance of OT in modulating the initiation and progression of labor remains unclear. In this study, we showed the roles of OT with onset of labor and also the arginine vasopressin (AVP) effect on urine volume in vivo using both wild type (WT) and placental leucine aminopeptidase (P-LAP)-deficient (KO) mice. OT (1, 2, 2.5 U/day) or recombinant P-LAP (0.01 U/day) was continuously infused from gestation day 15.5 in WT and P-LAP KO mice. Duration until onset of labor was observed. Before and after administration of AVP (1 U/day) in WT and P-LAP KO mice, urine volume was measured. A significant shortening of pregnancy term was observed in P-LAP KO mice. Continuous infusion of OT (1 U/day) revealed that P-LAP KO mice resulted in premature delivery (OT hypersensitivity). We could observe a significant decrease of urine volume in P-LAP KO mice by administration of AVP. Administration of recombinant P-LAP in WT mice resulted in the delay of the onset of labor about 1.5 days compared with control mice. Our present study shows that the regulation of the onset of labor mainly depends on OT and its degradation by P-LAP and also the possible role of P-LAP in the regulation of urine output. P-LAP might be involved in the increased OT sensitivity just prior to onset of labor and also in the onset of labor by degradation of OT.

    Full Text Available Low birth weight is commonly attributed to malaria in pregnancy, but the cellular and molecular mechanisms that underlie this poor birth outcome are incompletely understood. A universally described histopathological feature of placental malaria is excessive deposition of fibrin, the end-product of the coagulation cascade. This study was conducted to compare fibrin deposit in pregnant mice that infected by Plasmodium berghei (treatment group to the normal pregnant mice (control group and its association with fetal weight. This research is in vivo experimental laboratory study that used 18 pregnant Balb/c mice which divided to the control the group (8 mice and treatment group (9 mice infected by P.berghei. Placentas were staining with Haematoxylin-Eosin (HE for fibrin deposits examination whereas fetal weight was performed with Mettler analytical balance AE 50. Fetal weight of the treatment group was lower than those of the control group (t test, p=0,002. Fibrin deposits were increased in the treatment group (t test, p=0,005 and influenced weight of fetuses (Spearman r= -0,586, p= 0,014. Weights of fetuses are interfered by fibrin deposits during malaria infection.

    To investigate the effects of chlorella on methylmercury (MeHg) transfer to the fetus during pregnancy, female C57BL/6N mice (aged 10 weeks) were housed for 7 to 8 weeks, from 4 weeks before mating to birth, with diets containing 0% or 10% chlorella powder (CP) and MeHg-containing drinking water (2 µg Hg/ml). The consumption volume of the MeHg-containing water was limited to 15 ml/mouse/week throughout the experiment. Distilled water and a basal diet (0% CP) was given to control mice. Except for the mating period, during the 5(th) week, mice were housed individually until parturition. Two neonates were randomly selected from each mother mouse within 24 hr after parturition for Hg analysis of the blood, brain, liver, and kidneys. Mother mice were sacrificed on the same day as neonates to obtain tissue samples for Hg analysis. The blood and brain Hg levels of both neonates and mothers in the CP diet group were significantly lower than those in the basal diet group. Although the hepatic and renal Hg levels were not significant in mothers between the two dietary groups, in neonates, the CP diet group showed significantly lower Hg levels in these tissues than the basal diet group. The results obtained here revealed that continuous CP intake suppressed MeHg transfer to the fetus, in addition to effective suppressing MeHg accumulation in brains of the mothers.

    Expression patterns of sugars on the mucosal surface of the uterus in pregnant mice were investigated by using 21 kinds of lectins. In the uterine mucosa, the GlcNAc group tended to express a positive reaction before pregnant day 10, but the glucose/mannose group generally expressed a positive reaction after pregnant day 10. On the other hand, the fucose group expressed a negative reaction during all periods in pregnancy. These findings were almost the same on both the mesometrial side and anti-mesometrial side of the uterus. These differences of sugar expression probably reflect the functional change of the mucosa during pregnancy and the alteration of sugar expression may give a chance for pathogens to infect in the uterus with limited periods.

    Ruta graveolens L. is used in many countries, including Brazil, as an abortifacient. To determine its effect on pregnancy, the lyophilized hydroalcoholic extract of its aerial parts was administered orally at a dose of 1000 mg/kg per day to mice between the first and third day of pregnancy (DOP), between the fourth and sixth DOP or between the seventh and ninth DOP. The extract did not cause preimplantation embryonic loss or reabsorptions. Fetal death was found. Estrogenic activity was not exhibited by the extract.

    The mechanism of birth defects induced by folate deficiency was focused on mainly in fetal development. Little is known about the effect of folate deficiency on the maternal uterus, especially on decidual angiogenesis after implantation which establishes vessel networks to support embryo development. The aim of this study was to investigate the effects of folate deficiency on decidual angiogenesis. Serum folate levels were measured by electrochemiluminescence. The status of decidual angiogenesis was examined by cluster designation 34 (CD34) immunohistochemistry and the expression of angiogenic factors, including vascular endothelial growth factor A (VEGFA), placental growth factor (PLGF), and VEGF receptor 2 (VEGFR2) were also tested. Serum levels of homocysteine (Hcy), follicle stimulating hormone (FSH), luteinizing hormone (LH), prolactin (PRL), progesterone (P4), and estradiol (E2) were detected by Enzyme-linked immunosorbent assay. The folate-deficient mice had a lower folate level and a higher Hcy level. Folate deficiency restrained decidual angiogenesis with significant abnormalities in vascular density and the enlargement and elongation of the vascular sinus. It also showed a reduction in the expressions of VEGFA, VEGFR2, and PLGF. In addition, the serum levels of P4, E2, LH, and PRL were reduced in folate-deficient mice, and the expression of progesterone receptor (PR) and estrogen receptor α (ERα) were abnormal. These results indicated that folate deficiency could impaire decidual angiogenesis and it may be related to the vasculotoxic properties of Hcy and the imbalance of the reproductive hormone.

    The mechanism by which nanoparticles cross the placental barrier was studied by using isotopic tracers. The abortion rates and other related data were counted and analysed in pregnant mice with different pregnancy times. Results showed that oxidised multi-walled carbon nanotubes (oMWCNTs) crossed the placental barrier and entered the foetus body. The abortion rates in the pregnant mice depended on pregnancy times. The abortion rates in the first-time, second-time and fourth-time pregnant mice were 70%, 40% and 50%, respectively. The maternal body weight gain was inhibited until gestational ages of 13, 10 and 11 d. oMWCNTs decreased the serum progesterone level and increased the serum oestradiol level in a dose- and time-dependent manner. However, this effect decreased with gestational age. The histology and vascular endothelial growth factor/reactive oxygen species content in the placenta showed that oMWCNTs narrowed the blood vessel and decreased the number of blood vessels in the placenta.

    Full Text Available Iron deficiency and iron deficiency anemia during pregnancy call for safe treatment options that raise maternal hemoglobin levels and counterbalance iron demand and blood volume expansion while minimizing risks for the growing fetus. This retrospective study describes experience with intravenous ferric carboxymaltose given to pregnant women in a tertiary hospital in Spain. In a 5-year period, 95 pregnant women who had pretreatment hemoglobin <10 g/dL and at least one time of ferric carboxymaltose administration during pregnancy were included. Main outcome measures were week of pregnancy at iron administration, Hb levels before and after treatment, neonatal 5-minute Apgar scores, and birth weight. The majority received one dose of ferric carboxymaltose (1000 mg iron during advanced pregnancy (median 31 weeks; interquartile range [IQR]: 27; 37 weeks with minor to no adverse outcomes. Overall, median Hb increased from 8.5 g/dL (8.1; 8.9 g/dL before treatment to 11.0 g/dL (9.9; 11.7 g/dL after treatment. Normal Apgar scores were observed in all 97 infants (median birth weights 3560 g, 3270, and 3798 g. Four women received ferric carboxymaltose in the first trimester and twenty-eight during the second trimester without adverse outcomes for mother or child. These cases add to the evidence that ferric carboxymaltose administration during pregnancy is effective and safe.

    Full Text Available A number of factors influence the development of tolerance, including the nature, concentration and mode of antigen presentation to the immune system, as well as the age of the host. The studies were conducted to determine whether immunizing pregnant mice with liposome-encapsulated DNA vaccines had an effect on the immune status of their offspring. Two different plasmids (encoding antigens from HIV-1 and influenza virus were administered intravenously to pregnant mice. At 9.5 days post conception with cationic liposomes, injected plasmid was present in the tissues of the fetus, consistent with trans-placental transfer. When the offspring of vaccinated dams were immunized with DNA vaccine, they mounted stronger antigen-specific immune responses than controls and were protected against challenge by homologous influenza virus after vaccination. Moreover, such immune responses were strong in the offspring of mothers injected with DNA plasmid 9.5 days after coitus. These results suggest that DNA vaccinated mothers confer the antigen-specific immunity to their progeny. Here we describe the methods in detail as they relate to our previously published work.

    Full Text Available Background: Single dose of Nevirapine to prevent mother to child transmission of HIV is the commonest preventive regimen in resource-limited countries. Objectives: The objective of this study was to detect drug-resistant virus after single dose of Nevirapine (sdNVP provided to delivering HIV seropositive (HIV+ve women and to evaluate the time taken for its decay. Results: Of the 36 consenting HIV+ve pregnant women enrolled into the study, the mean hemoglobin and total lymphocyte counts were 10.8 g/dl and 1843 cells/mm 3 , respectively. Mean CD4 counts in 64% of women was 363 cells/mm 3 and mean viral load for 16/36 women was 28,143 copies/ml of plasma. Nevirapine-resistance mutations were detected in 28% of women at delivery; using OLA (Oligonucleotide Ligation Assay. K103N mutations were seen in 19.4% of women while the Y181C mutation was seen in 5%. Both the mutations were detected in 2.7% of women. Sequential blood samples collected at delivery, 7-10 days, 6 weeks, 4 months, 6 months and one year postpartum showed that 81% of K103N mutations and 66.7% of Y181C mutations were detected at 6 weeks postpartum . Wild-type virus had replaced the mutants by one year postpartum in all women except one. Conclusion : These observations are relevant for future treatment with antiretroviral therapy in these women for their HIV disease.

    Zika virus (ZIKV) crosses the placenta and causes congenital disease. Here we develop an animal model utilizing direct ZIKV inoculation into the uterine wall of pregnant, immunocompetent mice to evaluate transplacental transmission. Intrauterine inoculation at embryonic day (E) 10, but not E14, with African, Asian or American strains of ZIKV reduces fetal viability and increases infection of placental and fetal tissues. ZIKV inoculation at E10 causes placental inflammation, placental dysfunction and reduces neonatal brain cortical thickness, which is associated with increased activation of microglia. Viral antigen localizes in trophoblast and endothelial cells in the placenta, and endothelial, microglial and neural progenitor cells in the fetal brain. ZIKV infection of the placenta increases production of IFNβ and expression of IFN-stimulated genes 48 h after infection. This mouse model provides a platform for identifying factors at the maternal–fetal interface that contribute to adverse perinatal outcomes in a host with an intact immune system. PMID:28220786

    Full Text Available T-2 toxin is a cytotoxic secondary fungal metabolite that belongs to the trichothecene mycotoxin family. This mycotoxin is a well known inhibitor of protein synthesis through its high binding affinity to peptidyl transferase, which is an integral part of the ribosomal 60s subunit, and it also inhibits the synthesis of DNA and RNA, probably secondary to the inhibition of protein synthesis. In addition, T-2 toxin is said to induce apoptosis in many types of cells bearing high proliferating activity. T-2 toxin readily passes the placenta and is distributed to embryo/fetal tissues, which include many component cells bearing high proliferating activity. This paper reviews the reported data related to T-2 toxin-induced maternal and fetal toxicities in pregnant mice and rats. The mechanisms of T-2 toxin-induced apoptosis in maternal and fetal tissues are also discussed in this paper.

    Full Text Available Pregnancy is a leading risk factor for severe complications during an influenza virus infection. Women infected during their second and third trimesters are at increased risk for severe cardiopulmonary complications, premature delivery, and death. Here, we establish a murine model of aerosolized influenza infection during pregnancy. We find significantly altered innate antiviral responses in pregnant mice, including decreased levels of IFN-β, IL-1α, and IFN-γ at early time points of infection. We also find reduced cytotoxic T cell activity and delayed viral clearance. We further demonstrate that pregnancy levels of the estrogen 17-β-estradiol are able to induce key anti-inflammatory phenotypes in immune responses to the virus independently of other hormones or pregnancy-related stressors. We conclude that elevated estrogen levels result in an attenuated anti-viral immune response, and that pregnancy-associated morbidities occur in the context of this anti-inflammatory phenotype.

    Plants belonging to Rhodiola kirilowii species, members of Rhodiola genus and Crassulaceae family, grow wildly in Tibet, Mongolia and China mountains and are traditionally used as adaptogens, antidepressants and anti-inflammatory remedies. Nowadays, R. kirilowii is cultivated in some countries, also in Poland. In our previous papers we reported immuno- and angio-modulatory effects of aqueous and hydro-alcoholic extracts of radix and rhizome of this plant in non-pregnant and pregnant mice. The aim of the present study was to evaluate the effect of feeding pregnant and further lactating mice these extracts on selected thymus function parameters in adult progeny. The counts of M-30+ apoptotic cells, in the thymuses obtained from progeny of mice fed during pregnancy and lactation water or 50% water-alcoholic extract of Rhodiola kirilowii, were significantly lower (p<0.05) than apoptotic cells counts observed in the control mice. No significant differences in the counts of IL-7-positive cells in the thymuses obtained from progeny of the control mice and mothers treated with water or hydro-alcohol extracts of Rhodiola kirilowii were observed.

    The distribution of /sup 74/As-labelled and arsenite in pregnant mice and a monkey has been studied by autoradiography and gamma counting of isolated tissues, and their in vitro toxicity to a chondrogenic system has been investigated. With both arsenic forms, given as single intravenous injections to the mother, the /sup 74/As-arsenic appeared to pass the mouse placenta relatively freely and approximately to the same extent. The retention time in material tissues including the placenta was, however, around three times longer with arsenite than with arsenate. In early gestation, high activity was registered in the embryonic neuroepithelium, which correlates well with reported CNS malformations in rodents. In late gestation, the distribution pattern was more like that in the adults. Accumulation in skin and squamous epithelia of the upper gastrointestinal tract (oral cavity, oesophagus and oesophageal region of stomach) dominated the distribution picture, especially at a long survival interval. Arsenate, but not arsenite, showed affinity for the calcified areas of the skeleton. A marmoset monkey in late gestation receiving arsenite showed a somewhat lower rate of placental transfer than the mice. Skin and liver had the highest concentrations (at 8 hrs), both in mother and foetuses. This species is known not to methylate arsenic, resulting in stronger binding and longer retention times of arsenic as compared with other species. The stronger binding in maternal tissues may possibly explain the lower rate of placental transfer. Arsenite was shown to inhibit cartilage formation in a chick limb bud mesenchymal spot culture system (ED50 approximately 5-10..mu..M) while arsenate seemed to be without effect at concentrations up to 200 ..mu..M (highest tested). Arsenate, however, showed a potential of the arsenite toxicity.

    Indoleamine 2,3-dioxygenase (IDO) initiated tryptophan degradation in the placenta has a role in the prevention of allogeneic fetus rejection by T-cells. The present study aimed to investigate the relationship between IDO and CD4+CD25+Foxp3+ T cells in pregnant mice. The percentage of CD4+CD25+Foxp3+ T cells in peripheral blood mononuclear cells (PBMC) and IDO mRNA levels were detected in pregnant mice. The non-pregnant mice were used as control in this study. To confirm the effect of IDO, 1-methyl-trytophan (IDO inhibitor) was used in this study. The percentage of CD4+CD25+Foxp3+T cells in PBMC in pregnant mice was significantly higher than this in non-pregnant mice controls from day-6 to the end of the study (p<0.05). IDO mRNA levels in PBMC also markedly increased after pregnancy. The upregulation of IDO expression reached a maximum at day 18 after pregnancy (p<0.05). Compared to the pregnant group, the inhibitor could significantly decrease the IDO expression and Treg percentage (p<0.05). There was a positive association between IDO mRNA and CD4+CD25+Foxp3+ T cells percentage. The results suggested IDO might play a role in the generation of CD4+CD25+Foxp3+ T cells in pregnant mice.

    Full Text Available Background: The objective of the present study was to investigate the ability of butanolic extract from leaves of Chrysanthemum fontanesii, vitamin E and C to modulate ethanol-Induced toxicity and oxidation damage in maternal and fetal tissues of mice. Butanolic extract from leaves of Chrysanthemum fontanesii (200 mg/Kg per day, vitamin E (100mg/Kg per day and C (8.3mg/Kg per day were administered by gavage to groups of pregnant mice from the 6 th to 17 th day of gestation. A number of animals received plant extract, vitamin E and C, also treated with an oral administration of ethanol (0.02ml/g of 25% v/v absolute ethanol in water per day in same conditions. On day 18 of gestation, pregnant mice were killed, fetus, placenta, fetal liver, liver, kidneys and brain were removed, homogenised and used for determination of lipid peroxidation (LPO using TBARS method. Embryotoxicity was assessed by counting the number of live and dead fetus and growth retardation. Results: Severe alterations in all biomarkers were observed after injury with ETOH. ETOH produced significant decreases in fetal weight and significant increases in embryolethality and lipid peroxidation relative to control values. Treatment with Chrysanthemum fontanesii extract, vitamin C and vitamin E resulted in markedly decreased embryolethality and fetal growth retardation, while increased fetal weight were observed. Conclusion: The butanolic extract from leaves of Chrysanthemum fontanesii, vitamin E and C protected against ethanol induce fetal and maternal toxicity as revealed by the decrease in the extent of lipid peroxidation. So that butanolic extract from leaves of Chrysanthemum fontanesii posses in vivo antioxidant properties.

    HIV-infected pregnant women are particularly more susceptible to the deleterious effects of malaria infection particularly anaemia. In order to prevent opportunistic infections and malaria, a policy of daily co-trimoxazole prophylaxis without the standard Suphadoxine-Pyrimethamine intermittent preventive treatment (SP-IPT) was introduced to all HIV infected pregnant women in the year 2011. However, there is limited information about the effectiveness of this policy. This was a cross sectional study conducted among HIV-infected pregnant women receiving co-trimoxazole prophylaxis in eight public health facilities in Kinondoni Municipality from February to April 2013. Blood was tested for malaria infection and anaemia (haemoglobin anaemia. Pearson chi-square test, Fischer's exact test and multivariate logistic regression were used in the statistical analysis. This study enrolled 420 HIV infected pregnant women. The prevalence of malaria infection was 4.5%, while that of anaemia was 54%. The proportion of subjects with poor adherence to co-trimoxazole was 50.5%. As compared to HIV infected pregnant women with good adherence to co-trimoxazole prophylaxis, the poor adherents were more likely to have a malaria infection (Adjusted Odds Ratio, AOR = 6.81, 95% CI = 1.35-34.43, P = 0.02) or anaemia (AOR = 1.75, 95% CI = 1.03-2.98, P = 0.039). Other risk factors associated with anaemia were advanced WHO clinical stages, current malaria infection and history of episodes of malaria illness during the index pregnancy. The prevalence of malaria was low; however, a significant proportion of subjects had anaemia. Good adherence to co-trimoxazole prophylaxis was associated with reduction of both malaria infection and anaemia among HIV infected pregnant women.

Methods  Thirty female BALB/c mice were divided into three groups at random (n=10 per group: healthy pregnancy (HP group, asthma in pregnancy (AP group and dexamethasone (DXM treated group (DXM group. The mice were treated as follows: those in AP and DXM groups were sensitized with an intraperitoneal injection of chicken ovalbumin-aluminum hydroxide [OVA/A1(OH3] suspension on days 0, 7 and 14. The HP mice were sensitized with normal saline (NS following the same protocol. All the mice were then bred with male BALB/c male mice. Pregnant mice in AP and DXM groups were exposed to 40-minute of 50g/L OVA aerosol for seven consecutive days starting from day 21. Dexamethasone in a dose of 1mg/kg was injected intraperitoneally in DXM mice 30 minutes before inhaling 50g/L OVA aerosol, while the HP group received NS only. The airway responsiveness to corresponding concentrations of inhaled acetylcholine was recorded 24h after the final OVA challenge. The index of airflow obstruction was expressed as enhanced pause (Penh and its mean value after each nebulization. The airway tone is further expressed as the Penh(% after being normalized by the baseline value. Total and differential cell counts in bronchoalveolar lavage fluid (BALF were carried out in each sample. The histological changes in the lungs were assessed using light microscopy. The propotions of Th17 and Treg cell in mice peripheral blood cells were calculated and the Th17/Treg ratio was determined by flow cytometry. IL-17, IL-23, IFN-γand RORγt levels in the serum of mice were quantified by using ELISA technique. RT-PCR and Western blotting were performed to determine the levels of IL-17, RORγt, IL

    Full Text Available Angiogenesis plays an important role in many physiological processes, among them the formation of tissues and organs during embryogenesis. A lot of medicinal plants exhibit angiomodulatory properties. This creates the need for a thorough check of whether the plant extracts that we would like to give to pregnant women in order to increase their resistance to bacterial or viral infection will have negative effects on angiogenesis, and consequently on fetal development. This paper seeks to investigate the effect of serum of pregnant and nursing Balb/c mice that received aqueous (RKW or hydro-alcoholic (RKW-A R. kirilowii extracts (20 mg/kg, or epigallocatechin (0.2 mg/kg, on the in vitro proliferation and migration of mouse endothelial cell line HECa10. Of the 15 identified polyphenols in the extracts by HPLC, 8 were present in the sera. Chemical analysis revealed higher salidroside, kaempferol, chlorogenic acid, bFGF and VEGF concentration in RKW-A sera than in the sera of RKW group of mice. RKW-A and EGC sera did not affect migration of endothelial cells, however we noted some increase of migrating cells after RKW-sera treatment. RKW and EGC sera did not affect proliferation of endothelial cells. Sera of mothers from RKW-A group impaired the proliferation of endothelial cells in comparison to other groups. These data allow us to assume that Rhodiola kirilowii hydro-alcoholic extract (RKW-A is potentially able to modulate pre- and post- natal angiogenesis what might influence the development of organs in progeny. Sera of RKW mothers have not harm the proliferation of endothelial cells, despite they also contain antiangiogenic catechins and salidroside. This suggests the existence in RKW-A extract and in RKW-A sera of some other, as yet unidentified substances influencing endothelial cells proliferation.

    Pregnant women are at high risk for severe influenza disease outcomes, yet insights into the underlying mechanisms are limited. Here, we present models of H1N1 infection in syngenic and allogenic pregnant mice; infection in the latter mirrors the severe course of 2009 pandemic influenza in pregnant women. We found that the anti-viral immune response in the pregnant host was significantly restricted as compared to the non-pregnant host. This included a reduced type I interferon response as well as impaired migration of CD8(+) T cells into the lung. The multi-faceted failure to mount an anti-viral response in allogenic pregnant mice resulted in a less stringent selective environment that promoted the emergence of 2009 H1N1 virus variants that specifically counteract type I interferon response and mediate increased viral pathogenicity. These insights underscore the importance of influenza vaccination compliance in pregnant women and may open novel therapeutic avenues. Copyright © 2017 Elsevier Inc. All rights reserved.

    Full Text Available BACKGROUND: Chronic hyperglycemia-associated inflammation plays critical roles in disease initiation and the progression of diabetic complications, including Alzheimer's disease (AD. However, the association of chronic hyperglycemia with acute inflammation of the central nervous system in the progression of AD still needs to be elucidated. In addition, recent evidence suggests that Glucagon-like peptide-1 receptor (GLP-1R protects against neuronal damage in the brain. Therefore, the neuroprotective effects of the GLP-1R agonist exendin-4 (EX-4 against hyperglycemia/lipopolysaccharides (LPS damage were also evaluated in this study. METHODOLOGY/PRINCIPAL FINDINGS: Ten days after streptozotocin (STZ or vehicle (sodium citrate treatment in mice, EX-4 treatment (10 µg/kg/day was applied to the mice before intrahippocampal CA1 injection of LPS or vehicle (saline and continued for 28 days. This study examined the molecular alterations in these mice after LPS and EX4 application, respectively. The mouse cognitive function was evaluated during the last 6 days of EX-4 treatment. The results showed that the activation of NF-κB-related inflammatory responses induced cognitive dysfunction in both the hyperglycemic mice and the mice that received acute intrahippocampal LPS injection. Furthermore, acute intrahippocampal LPS injection exacerbated the impairment of spatial learning and memory through a strong decrease in monoaminergic neurons and increases in astrocytes activation and apoptosis in the hyperglycemic mice. However, EX-4 treatment protected against the cognitive dysfunction resulting from hyperglycemia or/and intrahippocampal LPS injection. CONCLUSIONS/SIGNIFICANCE: These findings reveal that both hyperglycemia and intrahippocampal LPS injection induced cognitive dysfunction via activation of NF-κB-related inflammatory responses. However, acute intrahippocampal LPS injection exacerbated the progression of cognitive dysfunction in the

    Caffeine is the psychostimulant most consumed worldwide. Anxiogenic effects of caffeine have been described in adult animals with controversial findings about its anxiogenic potential. Besides, the effects of caffeine on anxiety with aging are still poorly known. In this study, adult mice (6months old) started to receive caffeine (0.3 and 1.0mg/mL, drinking water) during 12-14months only in the light cycle and at weekdays. The open field (OF) and elevated plus maze (EPM) testing were used to determine the effects of caffeine on anxiety-related behavior in adult and aged mice (18-20months old). Because aging alters synaptic proteins, we also evaluated SNAP-25 (as a nerve terminals marker), GFAP (as an astrocyte marker) and adenosine A1 and A2A receptors levels in the cortex. According to the OF analysis, caffeine did not change both hypolocomotion and anxiety with aging. However, aged mice showed less anxiety behavior in the EPM, but after receiving caffeine (0.3mg/mL) during adulthood they were anxious as adult mice. While SNAP-25 and adenosine A2A receptors increased with aging, both GFAP and adenosine A1 receptors were not affected. Caffeine at moderate dose prevented the age-related increase of the SNAP-25, with no effect on adenosine A2A receptors. The absence of effect for the highest dose suggests that tolerance to caffeine may have developed over time. Aged mice showed high responsiveness to the OF, being difficult to achieve any effect of caffeine. On the other hand this substance sustained the adult anxious behavior over time in a less stressful paradigm, and this effect was coincident with changes in the SNAP-25, suggesting the involvement of this synaptic protein in the ability of caffeine to preserve changes related to emotionality with aging.

    Pre-eclampsia, the development of hypertension and proteinuria or end-organ damage during pregnancy, is a leading cause of both maternal and fetal morbidity and mortality, and there are no effective clinical treatments for pre-eclampsia aside from delivery. The development of pre-eclampsia is characterized by maladaptation of the maternal immune system, excessive inflammation and endothelial dysfunction. We have reported that detection of extracellular RNA by the Toll-like receptors (TLRs) 3 and 7 is a key initiating signal that contributes to the development of pre-eclampsia. PLacental eXpanded (PLX-PAD) cells are human placenta-derived, mesenchymal-like, adherent stromal cells that have anti-inflammatory, proangiogenic, cytoprotective and regenerative properties, secondary to paracrine secretion of various molecules in response to environmental stimulation. We hypothesized that PLX-PAD cells would reduce the associated inflammation and tissue damage and lower blood pressure in mice with pre-eclampsia induced by TLR3 or TLR7 activation. Injection of PLX-PAD cells on gestational day 14 significantly decreased systolic blood pressure by day 17 in TLR3-induced and TLR7-induced hypertensive mice (TLR3 144-111 mmHg; TLR7 145-106 mmHg; both Pinflammation and placental injury, increased markedly in both groups of TLR-induced hypertensive mice, were reduced by PLX-PAD cells. Importantly, PLX-PAD cell therapy had no effects on these measures in pregnant control mice or on the fetuses. These data demonstrate that PLX-PAD cell therapy can safely reverse pre-eclampsia-like features during pregnancy and have a potential therapeutic role in pre-eclampsia treatment.

  11. A safe vaccine (DV-STM-07 against Salmonella infection prevents abortion and confers protective immunity to the pregnant and new born mice.

    Directory of Open Access Journals (Sweden)

    Vidya Devi Negi

    Full Text Available Pregnancy is a transient immuno-compromised condition which has evolved to avoid the immune rejection of the fetus by the maternal immune system. The altered immune response of the pregnant female leads to increased susceptibility to invading pathogens, resulting in abortion and congenital defects of the fetus and a subnormal response to vaccination. Active vaccination during pregnancy may lead to abortion induced by heightened cell mediated immune response. In this study, we have administered the highly attenuated vaccine strain DeltapmrG-HM-D (DV-STM-07 in female mice before the onset of pregnancy and followed the immune reaction against challenge with virulent S. Typhimurium in pregnant mice. Here we demonstrate that DV-STM-07 vaccine gives protection against Salmonella in pregnant mice and also prevents Salmonella induced abortion. This protection is conferred by directing the immune response towards Th2 activation and Th1 suppression. The low Th1 response prevents abortion. The use of live attenuated vaccine just before pregnancy carries the risk of transmission to the fetus. We have shown that this vaccine is safe as the vaccine strain is quickly eliminated from the mother and is not transmitted to the fetus. This vaccine also confers immunity to the new born mice of vaccinated mothers. Since there is no evidence of the vaccine candidate reaching the new born mice, we hypothesize that it may be due to trans-colostral transfer of protective anti-Salmonella antibodies. These results suggest that our vaccine DV-STM-07 can be very useful in preventing abortion in the pregnant individuals and confer immunity to the new born. Since there are no such vaccine candidates which can be given to the new born and to the pregnant women, this vaccine holds a very bright future to combat Salmonella induced pregnancy loss.

    Pregnancy is associated with complex immunoreactions. In the present study, the effect of SB-273005, an antagonist of αvβ3 integrin, on the alterations of T helper (Th) cells and their derived cytokines that occur during pregnancy was investigated in mice. Five non-pregnant mice were used as a negative control. Mice were impregnated by co-housing females and males at a ratio of 2:1 overnight and pregnancy was confirmed by the appearance of vaginal plugs the following morning. Day 1 (D1) pregnant mice were randomly divided into two groups (n=20) and were administered either dimethylsulfoxide (mock treatment) or SB-273005 (3 mg/kg) by gavage at D3, D4 and D5. At D8, the levels of Th1 and Th2 cells and interleukin (IL)-2 and IL-10 in the spleen and peripheral blood were determined using flow cytometry and enzyme-linked immunosorbent assay. Pregnancy significantly increased the ratio of Th2:Th1 cells in the spleen compared with that in non-pregnant mice (PSB-273005 (PSB-273005 reversed both processes (PSB-273005, indicating an important role for αvβ3 integrin in mediating these immunological alterations.

    Mothers with obesity or gestational diabetes mellitus have low circulating levels of adiponectin (ADN) and frequently deliver large babies with increased fat mass, who are susceptible to perinatal complications and to development of metabolic syndrome later in life. It is currently unknown if the inverse correlation between maternal ADN and fetal growth reflects a cause-and-effect relationship. We tested the hypothesis that ADN supplementation in obese pregnant dams improves maternal insulin sensitivity, restores normal placental insulin/mechanistic target of rapamycin complex 1 (mTORC1) signaling and nutrient transport, and prevents fetal overgrowth. Compared with dams on a control diet, female C57BL/6J mice fed an obesogenic diet before mating and throughout gestation had increased fasting serum leptin, insulin, and C-peptide, and reduced high-molecular-weight ADN at embryonic day (E) 18.5. Placental insulin and mTORC1 signaling was activated, peroxisome proliferator-activated receptor-α (PPARα) phosphorylation was reduced, placental transport of glucose and amino acids in vivo was increased, and fetal weights were 29% higher in obese dams. Maternal ADN infusion in obese dams from E14.5 to E18.5 normalized maternal insulin sensitivity, placental insulin/mTORC1 and PPARα signaling, nutrient transport, and fetal growth without affecting maternal fat mass. Using a mouse model with striking similarities to obese pregnant women, we demonstrate that ADN functions as an endocrine link between maternal adipose tissue and fetal growth by regulating placental function. Importantly, maternal ADN supplementation reversed the adverse effects of maternal obesity on placental function and fetal growth. Improving maternal ADN levels may serve as an effective intervention strategy to prevent fetal overgrowth caused by maternal obesity.

    To explore the pathogenesis in placental dysfunction and abruptio placentae, we analyzed the occurrence of placental cell apoptosis and the role of Fas and Fas ligand (L) in that process in an inflammatory placental dysfunction model of pregnant mice, using lipopolysaccharides (LPS). In the present study, Day 13 pregnant mice were injected i.p. with LPS (50 microg/kg) or saline as a control, and the placentas were isolated at various time points after the injection. Analysis of the isolated DNA in agarose-gel electrophoresis revealed a typical ladder pattern of bands consisting of 180-200 base pairs (bp), which is regarded as a hallmark of apoptosis. The intensity of the bands increased time-dependently, reaching a maximum level at 12 h after LPS injection. In accord with the biochemical data, histochemical analysis using terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling (TUNEL) revealed that nuclei positive for double-stranded DNA breaks were found in decidua, diploid trophoblasts in the basal zone, and spongiotrophoblasts. The number of positive nuclei was maximized at 12 h after LPS injection. As a next step, we investigated the possible involvement of Fas and Fas L in the induction of apoptosis of the placental cells after LPS injection. Western blot analysis indicated that LPS increased the expression of Fas and Fas L in the placenta by about 4-fold at 12 h and 18 h, respectively, after injection. The cells expressing Fas and Fas L were identified, using immunohistochemistry and nonradioactive in situ hybridization, as decidua, diploid trophoblasts in the basal zone, and spongiotrophoblasts. Furthermore, when the expression of 4-hydroxy-2-nonenal (HNE)-modified proteins was assessed to evaluate the relation of oxidative stress elicited by LPS to the induction of apoptosis, once again decidua, diploid trophoblasts in the basal zone, and spongiotrophoblasts were positive. Therefore, the placental dysfunction by LPS may be brought about

    Autoradiography was used to study the distribution of /sup 14/C-labelled ochratoxin A for up to 4 hr after its iv administration to mice at various stages of pregnancy. The highest /sup 14/C concentration was consistently found in the bile throughout the experimental period. The concentration of radioactivity in the tissues was found, in decreasing order, in the liver, kidney, blood, salivary glands, large vessels, brown fat, myocardium, uterus and lymphatic tissues. The toxin was shown to cross the placental barrier on day 9 of pregnancy, at which time it is most effective in producing fetal malformations.

    Highlights: • The influence of DEHP on the development of placenta was investigated. • DEHP disrupts the growth and development of placenta. • DEHP disrupts the formation of labyrinth vascularization. • DEHP inhibits the proliferation of ectoplacental cone and placenta. • DEHP induces the apoptosis of placenta via activated MAPK signaling pathway. - Abstract: Di-(2-ethylhexyl) phthalate (DEHP) is used as a plasticizer and widely dispersed in the environment. DEHP exposure reduces embryo implantations, increases embryonic loss, and decreases fetal body weights. However, no detailed information is available about the effect of DEHP on the placentation during pregnancy. Thus, our aim was to explore the effect of DEHP on the growth and development of placenta in vivo. Mice were administered DEHP by gavages at 125, 250, 500 mg/kg/day from gestational days (GD) 1 until sacrifice. Results showed that DEHP treatment significantly reduced the weight of placenta at GD 13. Histopathologically, in DEHP-treated group, the ectoplacental cones significantly became smaller at GD9, and total area of placenta and area of spongiotrophoblast were significantly reduced at GD 13. Expression levels of Ascl2, Esx1 and Fosl1 mRNA dramatically decreased in DEHP-treated placenta at GD 13. DEHP administration disrupted labyrinth vascularization of placentas, and inhibited proliferation and induced apoptosis of placenta by the activation of caspase-3 and -8, up-regulation of Bax and down-regulation of Bcl-2 mRNA and protein at GD 13. In conclusion, these results suggest that adverse pregnancy outcomes including low birth-weight and pregnancy loss exposed to DEHP are possibly mediated, at least in part, via the suppression of placental growth and development.

    A good proportion of pregnant women patronize traditional birth homes in Nigeria for ante-natal care. This study aimed at determining the prevalence, risk factors, and susceptibility profile of etiologic agents of urinary tract infection among ante-natal attendees in a traditional birth home in Benin City, Nigeria. Clean-catch urine was collected from 220 pregnant women attending a traditional birth home in Benin City, Nigeria. Urine samples were processed, and microbial isolates identified using standard bacteriological procedures. A cross-sectional study design was used. The prevalence of urinary tract infection among pregnant women was 55.0%, significantly affected by parity and gestational age (Pinfection was recorded among 13(10.7%) pregnant women, and was unaffected by maternal age, parity, gravidity, gestational age, and educational status. Irrespective of trimester Escherichia coli was the most prevalent etiologic agent of urinary tract infection, followed by Staphylococcus aureus. The flouroquinolones were the most effective antibacterial agents, while Sulphamethoxazole-trimetoprim, Amoxicillin, Nalidixic acid, and Nitrofurantoin had poor activity against uropathogens isolated. The prevalence of urinary tract infection among pregnant women was 55.0% and significantly affected by gestational age and parity. The most prevalent etiologic agent observed was Escherichia coli. With the exception of the flouroquinolones, aminoglycoside, and Amoxicillin-cluvanate, the activity of other antibiotics used on uropathogens were poor. Health education of the traditional birth attendant and her clients by relevant intervention agencies is strongly advocated.

    CD200 overexpression in transgenic mice increases skin, cardiac, and renal allograft survival. Elevated levels of soluble CD200 (sCD200) are found in the serum of cancer individuals. We investigated whether sCD200 levels increase in mice with prolonged graft survival. Control or CD200 BL/6 recipients of BALB/c cardiac or skin grafts received low-dose rapamycin (0.5 mg/kg) at 36-hr intervals, a dose shown previously not to augment the survival of control grafts or alter the host antigraft immunity or graft gene expression profiles. Separate groups received high-dose rapamycin (1.5 mg/kg). Serum was obtained at 8, 15, and 80 days after grafting and assayed for sCD200 (enzyme-linked immunosorbent assay), for the suppression of immunity in mixed leukocyte cultures (MLCs), for the induction of regulatory T cells able to suppress cytotoxic T lymphocyte induction in MLCs, and for the ability to transfer graft survival to naïve recipients. Both CD200 and conventional mice with early enhanced graft survival had increased levels of sCD200 in serum, which induced Tr1 able to suppress MLCs. Suppression was abolished after passage of serum over a CD200 immunoadsorbent column. Dendritic cells maturing in the presence of sCD200 serum could induce populations of Foxp3 regulatory T cells able to suppress MLCs in vitro. In CD200 mice with long-term surviving cardiac (skin) allografts in the absence of continued transgene induction (>80 days [>35 days]), sCD200 levels returned to baseline, with no loss of grafts, but sera were unable to suppress MLCs in vitro. sCD200 serum adoptively transferred increased graft survival to naïve mice. We conclude that monitoring sCD200 at early times after engraftment may predict allograft survival.

    Humoral and cellular immune responses are associated with protection against extracellular and intracellular pathogens, respectively. In the present study, we evaluated the effect of receiving human secretory immunoglobulin A (hsIgA) on the histopathology of the lungs of mice challenged with virulent Mycobacterium tuberculosis. The hsIgA was purified from human colostrum and administered to Balb/c mice by the intranasal route prior to infection with M. tuberculosis or in a pre-incubated formulation with mycobacteria, with the principal aim to study its effect on qualitative pulmonary histopathology. The intranasal administration of hsIgA and the pre-incubation of mycobacteria with this preparation was associated with the presence of organised granulomas with signs of immune activation and histological features related to efficient disease control. This effect was highly evident during the late stage of infection (60 days), as demonstrated by numerous organised granulomas with numerous activated macrophages in the lungs of treated mice. The administration of hsIgA to mice before intratracheal infection with M. tuberculosis or the pre-incubation of the bacteria with the antibody formulation induced the formation of well-organised granulomas and inflammatory lesions in lungs compared with non-treated animals which correlates with the protective effect already demonstrated by these antibody formulations.

  1. The Swiss iodized salt program provides adequate iodine for school children and pregnant women, but weaning infants not receiving iodine-containing complementary foods as well as their mothers are iodine deficient.

    If children and pregnant women in the population are iodine sufficient, it is generally assumed infants are also sufficient. But weaning infants may be at risk of iodine deficiency because iodized salt contributes little dietary iodine during this period. To fill this gap, iodine fortification of infant formula milk (IFM) and complementary foods (CF) is likely important. The objective of the study was to first confirm that Swiss school children and pregnant women remain iodine sufficient and then to assess iodine status in infancy and the relative contribution of breast milk and IFM/CF to their iodine intakes. We measured urinary iodine concentrations (UIC) in national cross-sectional samples of: 1) pregnant women (n=648); 2) school children (n=916); 3) infants at three time points: at 3-4 d after birth and at 6 and 12 months (n=875); and 4) breast-feeding mothers (n=507). We measured breast milk iodine concentrations in the mothers, assessed iodine sources in infant diets, and analyzed iodine content of commercial IFM/CFs (n=22) and salt samples from the school children's households (n=266). Median (m) UICs in pregnant women (162 μg/liter) and school children (120 μg/liter) were sufficient, and 80% of the household salt was adequately iodized (≥15 ppm). However, mUICs in infants not receiving IFM/CF were not sufficient: 1) mUIC in breast-fed infants (82 μg/liter) was lower than in non-breast-fed infants (105 μg/liter) (P<0.001) and 2) mUIC in breast-fed weaning infants not receiving IFM/CF (70 μg/liter) was lower than infants receiving IFM (109 μg/liter) (P<0.01). mUIC was low in lactating mothers (67 μg/liter) and median breast milk iodine concentration was 49 μg/kg. In countries in which iodized salt programs supply sufficient iodine to older children and pregnant women, weaning infants, particularly those not receiving iodine-containing IFM, may be at risk of inadequate iodine intakes.

Given its' reported significance in biofilm formation and the superior performance of S. aureus biofilm versus planktonic vaccine in the mouse mastitis model, it was of interest to determine the immunogenicity and protective potential of Protein A as a potential vaccine candidate against bovine mastitis using the mouse mastitis model. Pregnant Balb/c mice were immunised with Protein A emulsified in an alum-based adjuvant by subcutaneous (s/c or intramammary (i/mam routes. While humoral immune response of mice post-immunization were determined using indirect ELISA, cell-mediated immune response was assessed by estimation of interferon-gamma (IFN-γ produced by protein A-stimulated splenocyte supernatants. Protective potential of Protein A against experimental mastitis was determined by challenge of immunized versus sham-vaccinated mice by i/mam route, based upon manifestation of clinical symptoms, total bacterial load and histopathological damage to mammary glands. Significantly (p<0.05 higher levels of IgG1 isotype were produced in mice immunized by the s/c route. In contrast, significantly higher levels of the antibody isotype IgG2a were produced in mice immunized by the i/mam route (p<0.05. There was significant reduction (p<0.05 in bacterial loads of the mammary glands of mice immunized by Protein A regardless of the route of immunization, with medium level of clinical symptoms observed up to day 3 post-challenge. However, Protein A vaccine failed to protect immunized mice post-challenge with biofilm producing encapsulated S. aureus via i/mam route, regardless of the route of immunization, as measured by the level of mammary tissue damage. It was concluded that, Protein A in its' native state was apparently not a suitable candidate for inclusion

    Full Text Available Pregnancy-associated malaria (PAM is expressed in a range of clinical complications that include increased disease severity in pregnant women, decreased fetal viability, intra-uterine growth retardation, low birth weight and infant mortality. The physiopathology of malaria in pregnancy is difficult to scrutinize and attempts were made in the past to use animal models for pregnancy malaria studies. Here, we describe a comprehensive mouse experimental model that recapitulates many of the pathological and clinical features typical of human severe malaria in pregnancy. We used P. berghei ANKA-GFP infection during pregnancy to evoke a prominent inflammatory response in the placenta that entails CD11b mononuclear infiltration, up-regulation of MIP-1 alpha chemokine and is associated with marked reduction of placental vascular spaces. Placenta pathology was associated with decreased fetal viability, intra-uterine growth retardation, gross post-natal growth impairment and increased disease severity in pregnant females. Moreover, we provide evidence that CSA and HA, known to mediate P. falciparum adhesion to human placenta, are also involved in mouse placental malaria infection. We propose that reduction of maternal blood flow in the placenta is a key pathogenic factor in murine pregnancy malaria and we hypothesize that exacerbated innate inflammatory responses to Plasmodium infected red blood cells trigger severe placenta pathology. This experimental model provides an opportunity to identify cell and molecular components of severe PAM pathogenesis and to investigate the inflammatory response that leads to the observed fetal and placental blood circulation abnormalities.

    Brucella abortus S19 is a smooth strain used as live vaccine against bovine brucellosis. Smooth lipopolysaccharide (LPS) is responsible for its residual virulence and serological interference. Rough mutants defective of LPS are more attenuated but confers lower level of protection. We describe a modified B. abortus S19 strain, named as S19Δper, which exhibits intermediate rough phenotype with residual O-polysaccharide (OPS). Deletion of perosamine synthetase gene resulted in substantial attenuation of S19Δper mutant without affecting immunogenic properties. It mounted strong immune response in Swiss albino mice and conferred protection similar to S19 vaccine. Immunized mice produced higher levels of IFN-γ, IgG2a and thus has immune response inclined towards Th1 cell mediated immunity. Sera from immunized animals did not show agglutination reaction with RBPT antigen and thus could serve as DIVA (Differentiating Infected from Vaccinated Animals) vaccine. S19Δper mutant displayed more susceptibility to serum complement mediated killing and sensitivity to polymyxin B. Pregnant guinea pigs injected with S19Δper mutant completed full term of pregnancy and did not cause abortion, still birth or birth of weak offspring. S19Δper mutant with intermediate rough phenotype displayed remarkable resemblance to S19 vaccine strain with improved properties of safety, immunogenicity and DIVA capability for control of bovine brucellosis.

    Iron oxide nanoparticles have attracted much attention because of their potential applications, such as drug delivery, biomedical imaging, and photocatalysis. Due to their small size and the potential to cross the placental barrier, the risk to pregnant women and the developing fetus from exposure to nanoparticles is of great concern. The developmental toxicity and biodistribution of a single dose versus multiple doses of iron oxide nanoparticles with positive or negative surface charges were investigated in vivo. Multiple doses of positively-charged nanoparticles given over several days resulted in significantly increased fetal deaths and accumulation of iron in the fetal liver and placenta. These results indicate both positively and negatively charged iron oxide nanoparticles have the ability to cross the placenta and accumulate in the fetus, though greater bioaccumulation and toxicity was observed with a positively-charged surface coating.

    Immune phenomena during the preimplantation period of pregnancy are poorly understood. The aim of our study was to assess the capacity for antigen presentation of splenic antigen-presenting cells (APCs) derived from pregnant and pseudopregnant mice in in vitro conditions. Therefore, sorted CD11c+ dendritic cells and macrophages F4/80+ and CD11b+ presenting ovalbumin (OVA) were cocultured with CD4+ T cells derived from OT-II mice's (C57BL6/J-Tg(TcraTcrb)1100Mjb/J) spleen. After 132 hours of cell culture, proliferation of lymphocytes (ELISA-BrdU), activation of these cells (flow cytometry), cytokine profile (ELISA), and influence of costimulatory molecules blocking on these parameters were measured. We did not detect any differences in regulation of Th1/Th2 cytokine balance. CD86 seems to be the main costimulatory molecule involved in the proliferation response but CD80 is the main costimulatory molecule influencing cytokine secretion in pregnant mice. In conclusion, this study showed that CD80 and CD86 costimulatory molecules regulate OT-II CD4+ T lymphocyte proliferation and cytokine response in cocultures with antigen-presenting cells derived from pregnant and pseudopregnant mice. The implications of these changes still remain unclear. PMID:24771983

    We report the case of a 19-year-old young woman for whom was discovered a pregnancy at the end of the irradiation for a Hodgkin lymphoma (stage IV bone Bb), initially treated by chemotherapy. The radiotherapy delivered 36 Gy in infra-diaphragmatic volumes (lumbo-aortic, spleen, L5), beginning in a pregnant patient for less than 4 amenorrhea weeks. The calculated received fetal dose (literature data, measurement with software T.P.S., measurement on phantom) is high: it's between 2.8 and 5 Gy. With a current follow-up of 4 years since the radiotherapy's end, the patient is in complete remission and her child presents with a normal development for the age, in spite of the infra diaphragmatic irradiation.

    The intestinal microbiota is important for tolerance induction through mucosal immunological responses. The composition of the gut microbiota of an infant is affected by environmental factors such as diet, disease and antibiotic treatment. However, already in utero, these environmental factors can affect the immunological development of the foetus and influence the future gut microbiota of the infant. To investigate the effects of antibiotic treatment of pregnant mothers on the offspring's gut microbiome and diabetes development, we treated non-obese diabetic (NOD) mice with a cocktail of antibiotics during gestation and the composition of the gut microbiota, diabetes incidence and major gut-related T lymphocyte populations were investigated in the offspring. We observed a persistent reduction in the general diversity of the gut microbiota in the offspring from NOD mothers treated with antibiotics during gestation compared with offspring from control mothers. In addition, by clustering the present bacterial taxa with principal component analysis, we found a differential clustering of gut microbiota in the offspring from NOD mothers treated with antibiotics during gestation compared with offspring from control mothers. Offspring from NOD mothers treated with antibiotics during gestation also showed some immunological alterations in the gut immune system, which could be related to the diversity of the gut microbiome and influence modulation of diabetes development at 20 weeks. Our data point out maternal derangement of the intestinal microbiota as a potential environmental risk factor for T1D development.

    Although the neuromedin B receptor (NMBR), a bombesin receptor family member, has been implicated in thermoregulation and in stimulation of both urogenital and gastrointestinal smooth muscle contraction, its underlying role in labor onset and its associated molecular mechanisms remain poorly understood. We examined the relationship between temporal and spatial NMBR expression in the myometrium of pregnant mice and potential mechanistic pathways leading to labor onset. Resultant data indicate that NMBR expression peaked at term and before parturition. Maternal exposure to the NMBR agonist neuromedin B (NMB) shortened the gestational age of pups, an effect that was also observed after oxytocin administration. Both RELA (NFKB P65) DNA-binding activity and interleukin 6 (Il6) mRNA expression were greatest during parturition and after maternal exposure to the highest NMB concentration administered (150 μg/kg). Furthermore, a significant correlation was observed among NMBR mRNA expression, RELA DNA-binding activity, and Il6 mRNA expression. These data demonstrate that NMB and its receptor can induce the onset of labor via a RELA/IL6-mediated pathway.

    To describe characteristics, referrals, service utilization, and self-reported quit rates among pregnant and non-pregnant women enrolled in a smoking cessation quitline. This information can be used to improve strategies to increase pregnant and non-pregnant smokers' use of quitlines. We examined tobacco use characteristics, referral sources, and use of services among 1,718 pregnant and 24,321 non-pregnant women aged 18-44 years enrolled in quitline services in 10 states during 2006-2008. We examined self-reported 30-day quit rates 7 months after enrollment among 246 pregnant and 4,123 non-pregnant women and, within groups, used Chi-square tests to compare quit rates by type of service received. The majority of pregnant and non-pregnant callers, respectively, smoked ≥10 cigarettes per day (62 %; 83 %), had recently attempted to quit (55 %; 58 %), smoked 5 or minutes after waking (59 %; 55 %), and lived with a smoker (63 %; 48 %). Of callers, 24.3 % of pregnant and 36.4 % of non-pregnant women were uninsured. Pregnant callers heard about the quitline most often from a health care provider (50 %) and non-pregnant callers most often through mass media (59 %). Over half of pregnant (52 %) and non-pregnant (57 %) women received self-help materials only, the remainder received counseling. Self-reported quit rates at 7 months after enrollment in the subsample were 26.4 % for pregnant women and 22.6 % for non-pregnant women. Quitlines provide needed services for pregnant and non-pregnant smokers, many of whom are uninsured. Smokers should be encouraged to access counseling services.

  14. Effects of gestational stage and injection route on the corporeal distribution and placental transfer of selenium in pregnant mice

    Corporeal distribution and placental transfer of selenium after a single injection of sodium selenite (SS) were investigated over a period of 24 h with regard to the gestational stages of mice and the injection routes of SS. On day 16 of gestation, feto-placental accumulation of selenium was remarkably increased compared with that on day 12 following subcutaneous (sc) injection of SS. Selenium concentrations in the maternal liver, kidneys and lungs were higher on day 16 than on day 12. These results explain the occurrence of the enhanced abortion or maternal death due to SS injection (sc) on day 16 compared with that on day 12, in the previous study. Intravenous (iv) injection of SS caused increased selenium concentrations in most of the maternal organs and tissues but not in the placenta or the fetus compared with sc injection. This may explain the disappearance of the abortion-inducing effect of SS when iv injection is used. 12 references, 1 figure, 5 tables.

    This paper deals with the quantitative localization of Candida albicans in different parts of white micr gastrointestinal tract after oral inoculation of the yeast. Animals are previously treated with ampicillin, cortisone, or estradiol. Female pregnant and normal adult mice are also used. Our results show that the number of yeasts increases respectively in small intestine, stomach, caecum, and sigmoid. As compared with normal adult mice, C. albicans is more abundant in mice treated wtih ampicillin or cortisone whereas the yeast growth is lower in pregnant animals or in mice receiving estradiol. Moreover, male animals ordinarily show higher values than those found in female mice.

  16. Intravenous Exposure of Pregnant Mice to Silver Nanoparticles: Silver Tissue Distribution and Effects in Maternal and Extra-Embryonic Tissues and Embryos

    Austin, Carlye Anne

    This research explores the tissue distribution of silver, as well as adverse effects in pregnant mice and embryos, following prenatal silver nanoparticle (AgNP) exposure. Chapter one of this dissertation is a survey of the published literature on the reproductive and/or developmental toxicity of AgNPs. The available data indicate that AgNPs adversely affect sperm count, viability, and/or motility both in vivo and in vitro, and cause apoptosis and necrosis in spermatogonial stem cells and testicular cells. Additionally, AgNP exposure results in mortality and morphological deformities in fish embryos, but produces no adverse effects in chicken embryos. The current published research on in vivo AgNP exposure to mammals during gestation consists of only three studies, one of which is described in chapter two of this dissertation. These studies report results that may suggest a potential for adverse effects on fetal development (e.g. , decreased viability and fetal and placental weights, increased incidence of developmentally young embryos), but additional research is needed. Chapter two of this dissertation investigates the distribution of silver in tissues of pregnant mice and gestation day (GD) 10 embryos following intravenous maternal exposure to 50 nm AgNPs during early organogenesis (GDs 7-9). Examinations of embryo morphology and histology were also performed. Results demonstrated the presence of silver in all organs and tissues examined. Silver concentrations were highest in liver, spleen, and visceral yolk sac, and lowest in embryos. Groups of mice were also treated with soluble silver nitrate, and the pattern of silver tissue distribution following silver nitrate exposure was similar to that which followed AgNP treatment. Transmission electron microscopy-energy dispersive x-ray spectroscopy (TEM-EDS) confirmed the presence of vesicle-bound nanoparticulate silver in visceral yolk sac endoderm, but not mesoderm. This finding, along with the high silver

    Pregnancy induces transitory metabolic changes including increases in food intake and body fat deposition, as well as leptin and insulin resistance. Recent findings have suggested that increased hypothalamic expression of suppressor of cytokine signaling-3 (SOCS3) is a key mechanism responsible for triggering those metabolic adaptations. Because obesity is a risk factor for gestational metabolic imbalances, we aimed to study the role of SOCS3 during pregnancy in obese mice. Female mice carrying a deletion of SOCS3 in leptin receptor-expressing cells (SOCS3 KO mice) were exposed to a chronic high-fat diet (HFD), and we then studied their energy balance and glucose homeostasis during pregnancy. SOCS3 deletion did not prevent diet-induced obesity or changes in body weight and adiposity observed during pregnancy. However, the typical increase in food intake during mid- and late-pregnancy was blunted in SOCS3 KO females. We also observed a slight improvement in glucose homeostasis and increased leptin sensitivity in the arcuate nucleus of the hypothalamus in pregnant SOCS3 KO mice on HFD. Despite this, SOCS3 KO mice had an increased number of uterine reabsorptions and fewer fetuses compared to the controls. Compared to control animals, a reduction in proopiomelanocortin and an increase in oxytocin mRNA levels were observed in the hypothalamus of pregnant SOCS3 KO mice. In contrast to previous studies using lean animals, conditional SOCS3 ablation did not prevent major gestational metabolic changes in diet-induced obese mice. Our findings contribute to the understanding of the role of SOCS3 in mediating pregnancy-induced metabolic adaptations.

    Full Text Available The present study was undertaken to examine if microdoses of ultra-high diluted arsenic trioxide (a potentized homeopathic remedy, Arsenicum Album 200C, diluted 10-400 times have hepatoprotective potentials in mice subjected to repeated injections of arsenic trioxide. Arsenic intoxicated mice were divided into: (i those receiving Arsenicum Album-200C daily, (ii those receiving the same dose of diluted succussed alcohol (Alc 200C and (iii another group receiving neither drug nor succussed alcohol. Two other control groups were also maintained: one fed normal diet only and the other receiving normal diet and Alc-200C. Toxicity biomarkers like aspartate and alanine aminotransferases, glutathione reductase, catalase, succinate dehydrogenase, superoxide dismutase and reduced glutathione contents were periodically assayed keeping the observer “blinded”. Additionally, electron microscopic studies and gelatin zymography for matrix metalloproteinases of liver tissues were made at day 90 and 120. Blood glucose, hemoglobin, estradiol and testosterone contents were also studied. Compared to controls, Arsenicum Album-200C fed mice showed positive modulations of all parameters studied, thereby providing evidence of protective potentials of the homeopathic drug against chronic arsenic poisoning.

    Full Text Available The effects of pregnancy on the Oral Mucosa Disorder (OMD have been sporadically documented in some developed countries. Less known is the status of OMD during pregnancy in less developed/developing countries. Iran is no exception. This study assesses the prevalence of OMD in 200 pregnant women and compares the findings with the findings from a 200 non-pregnant woman of similar age distribution in Iran. The participants had been referred to a clinic to receive reproductive age-related services. Participants suffering from systemic chronic diseases, those on medications/drugs, smokers, needing biopsies, and those with urgent Oral Mucosal Lesion (OML treatments were excluded from the study. Oral mucosal of all 400 participants were examined. The participants’ age ranges were from 17 to 47; with the average age of 33.14 for one group; and 30.23 for the other group. Both groups had the same level of formal education. Out of 400 examined women; 62 had lesions, including 47 pregnant (23.5%; and 15 non-pregnant (7.5% women. This result shows that the OMD rate of occurrence was significantly higher among the pregnant women. Higher OML prevalence in pregnant women, as compared to the non-pregnant women, indicates the importance of timely oral examination of pregnant women and subsequent treatment plans for them.

    The tissue distribution of diazinon and the inhibition of cholinesterase (ChE) activities in plasma, erythrocyte and brain were investigated using male rats and mice which received a single intraperitoneal (i.p.) dose of diazinon (20 or 100 mg/kg body wt) in olive oil. The blood diazinon level was estimated to reach a maximum at 1-2 h after the i.p. administration. It was demonstrated that the diazinon residue levels are the highest in the kidney, when comparing the distribution of diazinon among liver, kidney and brain in the animals after dosing. It was indicated that the ChE inhibition by diazinon exposure is greater in the plasma than in the erythrocytes for male mice, while its inhibition is greater in the erythrocytes for male rats. Brain ChE activity was also inhibited markedly in the mice after dosing.

    Use of soy supplements to inhibit cancer cell growth is increasing among patients due to the perception that phytoestrogens in soy inhibit carcinogenesis via induction of apoptosis. Genistein, the most prevalent phytoestrogen in soy, is a potent endocrine disruptor and tyrosine kinase inhibitor (TKI) that causes apoptosis in many cells types. Chemotherapeutic TKIs limit cancer cell growth via the same mechanisms. However, TKIs such as Sunitinib cause cardiotoxicity in a significant number of patients. Molecular interactions between Sunitinib and dietary TKIs like genistein have not been examined in cardiomyocytes. Significant lethality occurred in mice treated with Sunitinib and fed a phytoestrogen-supplemented diet. Isolated cardiomyocytes co-treated with genistein and Sunitinib exhibited additive inhibition of signaling molecules important for normal cardiac function and increased apoptosis compared with Sunitinib alone. Thus, dietary soy supplementation should be avoided during administration of Sunitinib due to exacerbated cardiotoxicity, despite evidence for positive effects in cancer.

    Cytomegalovirus (CMV) infections are associated with vascular diseases in the human population. We have previously shown vascular dysfunction in systemic and uterine arteries dissected from nonpregnant (NP) mouse CMV (mCMV)-infected mice that was further impaired during late pregnancy (LP). CMV attachment alone through glycoprotein B (GB) can generate signals that impact vascular tone regulation. However, the contribution of direct virus interactions with endothelium to the vascular dysfunction we previously observed after in vivo mCMV infection is not known. We used a pressure myograph system to infuse GB or whole intact mCMV inside arteries dissected from uninfected mice and assessed vasodilation to methacholine infused inside pressurized arteries rather than applied abluminally. These results were compared to those observed after methacholine infusion into untreated arteries dissected from mCMV-infected mice. In mesenteric arteries, vasodilation to infused methacholine did not differ among treatments in NP or LP groups in contrast to previously published studies. However, increased vasoconstrictor activity was unmasked after blocking thromboxane receptors or prostaglandin production. Vasodilation in uterine arteries from uninfected NP mice to infused methacholine was increased by both GB and whole intact mCMV pretreatment. Untreated uterine arteries from mCMV-infected NP mice showed even greater vasodilation. There was no effect of GB or whole intact mCMV pretreatment in uterine arteries from uninfected LP mice, whereas vasodilation to infused methacholine was reduced in untreated uterine arteries from mCMV-infected LP mice. CMV exerts direct effects on vascular function which should be considered during viral reactivation leading to viremia and during GB-based vaccine administration.

    Maternal undernutrition is linked with an elevated risk of diabetes mellitus in offspring regardless of the postnatal dietary status. This is also found in maternal micro-nutrition deficiency, especial chromium which is a key glucose regulator. We investigated whether maternal chromium restriction contributes to the development of diabetes in offspring by affecting DNA methylation status in liver tissue. After being mated with control males, female weanling 8-week-old C57BL mice were fed a control diet (CON, 1.19 mg chromium/kg diet) or a low chromium diet (LC, 0.14 mg chromium/kg diet) during pregnancy and lactation. After weaning, some offspring were shifted to the other diet (CON-LC, or LC-CON), while others remained on the same diet (CON-CON, or LC-LC) for 29 weeks. Fasting blood glucose, serum insulin, and oral glucose tolerance test was performed to evaluate the glucose metabolism condition. Methylation differences in liver from the LC-CON group and CON-CON groups were studied by using a DNA methylation array. Bisulfite sequencing was carried out to validate the results of the methylation array. Maternal chromium limitation diet increased the body weight, blood glucose, and serum insulin levels. Even when switched to the control diet after weaning, the offspring also showed impaired glucose tolerance and insulin resistance. DNA methylation profiling of the offspring livers revealed 935 differentially methylated genes in livers of the maternal chromium restriction diet group. Pathway analysis identified the insulin signaling pathway was the main process affected by hypermethylated genes. Bisulfite sequencing confirmed that some genes in insulin signaling pathway were hypermethylated in livers of the LC-CON and LC-LC group. Accordingly, the expression of genes in insulin signaling pathway was downregulated. There findings suggest that maternal chromium restriction diet results in glucose intolerance in male offspring through alterations in DNA methylation which

    The prevalence of anaemia during pregnancy is estimated to be 35-75% in sub-Saharan Africa and is associated with an increased risk of maternal mortality. We evaluated the frequency and factors associated with anaemia in HIV-infected women undergoing antiretroviral (ARV) therapy for prevention of mother-to-child transmission (PMTCT) enrolled in The Kisumu Breastfeeding Study 2003-2009. Maternal haematological parameters were monitored from 32 to 34 weeks of gestation to 2 years post-delivery among 522 enrolled women. Clinical and laboratory assessments for causes of anaemia were performed, and appropriate management was initiated. Anaemia was graded using the National Institutes of Health Division of AIDS 1994 Adult Toxicity Tables. Data were analysed using SAS software, v 9.2. The Wilcoxon two-sample rank test was used to compare groups. A logistic regression model was fitted to describe the trend in anaemia over time. At enrolment, the prevalence of any grade anaemia (Hb < 9.4 g/dl) was 61.8%, but fell during ARV therapy, reaching a nadir (7.4%) by 6 months post-partum. A total of 41 women (8%) developed severe anaemia (Hb < 7 g/dl) during follow-up; 2 (4.9%) were hospitalised for blood transfusion, whereas 3 (7.3%) were transfused while hospitalised (for delivery). The greatest proportion of severe anaemia events occurred around delivery (48.8%; n = 20). Anaemia (Hb ≥ 7 and < 9.4 g/dl) at enrolment was associated with severe anaemia at delivery (OR 5.87; 95% CI: 4.48, 7.68, P < 0.01). Few cases of severe anaemia coincided with clinical malaria (24.4%; n = 10) and helminth (7.3%; n = 3) infections. Resolution of anaemia among most participants during study follow-up was likely related to receipt of ARV therapy. Efforts should be geared towards addressing common causes of anaemia in HIV-infected pregnant women, prioritising initiation of ARV therapy and management of peripartum blood loss. © 2016 John Wiley & Sons Ltd.

    To understand roles of interleukin 6 (IL-6) family cytokines for pregnancy in mice, localization of IL-6 receptor (IL-6R) mRNA was investigated in non- and early pregnant uteri by in situ hybridization. IL-6R mRNA was expressed in all non-pregnant uteri and in pregnant uteri from the third day (Day 3) to the sixth day of pregnancy (Day 6; the day of plug = Day 1). IL-6R mRNA signals were detected in non-pregnant mice in the luminal and glandular epithelium. Signal strength varied according to the sexual cycle. There was no correlation between the signal strength of the IL-6R mRNA and the serum concentrations of progesterone and 17beta-estradiol, which show a monophasic rise in the non-pregnant sexual cycle. In pregnant mice, slight signals were detectable in the luminal and glandular epithelium on Day 3. IL-6R mRNA messages increased with progression towards Day 4, however, localization changed drastically on Day 5. Stromal cells abruptly expressed their mRNA on Day 5, and these cells strongly expressed it on Day 6. The function of IL-6R in the luminal and glandular epithelium might be different from that in the stroma during the implantation period. In addition, few signals were identified in the stromal cells adjacent to the luminal epithelium on Day 6. This suggests that there are two types of stromal cells on Day 6 in mice.

    received the rutine, the concentration of rutine in the group of non-pregnant females was 9.3 +/- 1.0 microg/ml of urine, and in the group of the pregnant ones 8.5 +/- 1.1 microg/ml of urine. In the lungs of non-pregnant animals exposed to tobacco smoke, the decreased permeability of vessels for the albumin-Evans blue complex was proven. The administration of rutine to non-pregnant and pregnant animals did not exert influence on the permeability of vessels in lungs. A similar result was obtained for the lungs of rats receiving the rutine, as well as those exposed to tobacco smoke. In the brain tissue of non-pregnant and pregnant animals, a slight decrease in the content of Evans blue was declared as a consequence of tobacco smoke impact. In the groups receiving the rutine, this flavonoid was declared to influence the blood supply of the brain tissue, and the permeability of the vascular walls. In the liver tissue of animals inhaling the tobacco smoke, the permeability of vascular walls for albumin-Evans blue complex was increased. The rutine did not affect significantly the permeability of vessels, whereas the exposure of pregnant females, which received rutine, to smoke decreased the content of Evans blue in the liver tissue. In the tissues of all tested females, no significant differences between the control groups and groups exposed to tobacco smoke as well as rutine+tobacco smoke were detected. The obtained results do not indicate, however, that in case of chronic exposure to tobacco smoke, the rutine has insignificant protective meaning.

    Objective To observe the expression changes in Thl7-related cytokines and retinoid acid receptor-related orphan receptor gamma t (ROR y t) in mouse model of asthma during pregnancy, and to explore the effects of dexamethasone (DXM) on Thl7 cell secretory function and airway inflammation in mice. Methods Thirty female BALB/c mice were divided into three groups at random (n=10 per group): healthy pregnancy (HP) group, asthma in pregnancy (AP) group and dexamethasone (DXM) treated group (DXM group). The mice were treated as follows: those in AP and DXM groups were sensitized with an intraperitoneal injection of chicken ovalbumin-aluminum hydroxide [OVA/A1(OH)3] suspension on days 0, 7 and 14. The HP mice were sensitized with normal saline (NS) following the same protocol. All the mice were then bred with male BALB/c male mice. Pregnant mice in AP and DXM groups were exposed to 40-minute of 50g/L OVA aerosol for seven consecutive days starting from day 21. Dexamethasone in a dose of lmg/kg was injected intraperitoneally in DXM mice 30 minutes before inhaling SOg/L OVA aerosol, while the HP group received NS only. The airway responsiveness to corresponding concentrations of inhaled acetylcholine was recorded 24h after the final OVA challenge. The index of airflow obstruction was expressed as enhanced pause (Penh) and its mean value after each nebulization. The airway tone is further expressed as the Penh(%) after being normalized by the baseline value. Total and differential cell counts in bronchoalveolar lavage fluid (BALF) were carried out in each sample. The histological changes in the lungs were assessed using light microscopy. The propotions of Thl7 and Treg cell in mice peripheral blood cells were calculated and the Thl7/Treg ratio was determined by flow cytometry. IL-17, IL-23, IFN- 7 and RORγ t levels in the serum of mice were quantified by using ELISA technique. RT-PCR and Western blotting were performed to determine the levels of IL-17, RORγ t, IL-23 and IFN

    The objective of this study was to provide trained labor support (doulas) to pregnant women in jail. A multiagency intervention project provided doula birth services to pregnant women in urban jails. Program evaluation included interviews with women and written satisfaction surveys of providers and correctional officers. A convenience sample of 18 incarcerated women received doula services. A doula visited each woman in jail antepartum to review expectations for labor and birth; during hospitalization, the doula provided continuous support throughout labor and birth. Doulas visited women postpartum to review birth events. Surveys administered to providers and officers demonstrated high satisfaction with the program. Qualitative interviews with 14 women indicated unanimous support for the services and documented women's major concerns. Findings support offering doula services to all pregnant women in custody and expanding doula services to include early and comprehensive intervention coordinated by nurses.

    The beta 2-sympathomimetic drug fenoterol (fenoterol hydrobromide, CAS 1944-12-3, Partusisten) is routinely used to inhibit uterine contractions (tocolysis). Investigations of plasma concentrations of those receiving i.v. or oral tocolysis often show different results, both within particular groups of pregnant women and in comparison with non-pregnant persons. The aim of this study was to determine the pharmacokinetics of fenoterol in pregnant women, an important factor which so far had not been known. Four healthy pregnant women with similar weight and gestational age and all with premature labor were administered a continuous intravenous infusion of 4 micrograms fenoterol/min. During and up to 24 hours after the end of the infusion, venous blood samples were taken in order to determine the fenoterol plasma concentrations by radioimmunoassay. From a steady state concentration (css) of 2242 +/- 391 pg/ml (x +/- S.E.), a non-linear two-phased plasma elimination was seen with half-lives t1/2 of 11.40 min and 4.87 h. The area under the plasma concentration-time curve (AUC0-12h) was 6.27 ng/ml x h. The total clearance (Cltot) was 114.8 l/h. These data are nearly the same as the data already known for healthy non-pregnant (male) volunteers. The deviations which are seen in the plasma concentrations in pregnant women in comparison to non-pregnant persons during or after continuous i.v. infusion can therefore not be caused by differences in the pharmacokinetics. Other factors, however, such as body weight and/or gestational age, might influence the results.

    ón con criterio para evitar posibles daños al feto.OBJECTIVE: To identify the use of medicines by pregnant women who receive care at the Brazilian universal healthcare system, specifically in the municipal district of Bandeirantes, Paraná. METHODS: A cross-sectional descriptive study was used. A sample of 205 women participated in the study. Data were collected from July 2006 to November 2007 using a structured questionnaire. RESULTS: A great number of participants (83.4% reported they had used at least one medicine during their pregnancy and 8.2% of them used over-the-counter medicines. The majority of the women (80.5% received warnings about the use of medicines during pregnancy. There was significant statistical relationship between the last 3 months of pregnancy and the increase in medicines use. Although Ferrous sulfate (45.0% and Paracetamol (43.4% offer serious risks to the fetus, these two medicines were among those most used by the participants. CONCLUSION: Pregnant women have been exposed to a variety of medicines. There is a need to improve the quality of care to pregnant women in order to prevent potential risks to the fetus.

    Key points Older pregnant women have a greater risk of operative delivery, still birth and post‐term induction.This suggests that maternal age can influence the timing of birth and processes of parturition.We have found that increasing maternal age in C57BL/6J mice is associated with prolongation of gestation and length of labour.Older pregnant mice also had delayed progesterone withdrawal and impaired myometrial function.Uterine ageing and labour dysfunction should be investigated further in older primigravid women. Abstract Advanced maternal age (≥35 years) is associated with increased rates of operative delivery, stillbirth and post‐term labour induction. The physiological causes remain uncertain, although impaired myometrial function has been implicated. To investigate the hypothesis that maternal age directly influences successful parturition, we assessed the timing of birth and fetal outcome in pregnant C57BL/6J mice at 3 months (young) and 5 months (intermediate) vs. 8 months (older) of age using infrared video recording. Serum progesterone profiles, myometrium and cervix function, and mitochondrial electron transport chain complex enzymatic activities were also examined. Older pregnant mice had a longer mean gestation and labour duration (P changes to the enzymatic activities of the mitochondrial electron transport chain complexes. In conclusion, 8‐month‐old mice provide a useful model of reproductive ageing. The present study has identified potential causes of labour dysfunction amenable to investigation in older primigravid women. PMID:28083928

Mice from all experimental groups received folate-free balanced diet + saccharose with folate diluted in water during their three-day mating period and thereafter 15 days until animals were put down. RESULTS: Mice from groups D and D/DS showed alopecia, pale eyes and adynamia while on folate-free saccharose water regimen. These symptoms disappeared after the introduction of saccharose with folate diluted in water. No statistical difference was noted among groups as to pregnancy, number of implants, live fetuses, reabsorption, late fetal death, serum folate levels and red blood cells count and no congenital abnormalities were identified in any groups by the end of the experiment. CONCLUSION: Saccharose is a suitable vehicle for the dietary supplementation of folate.

    The current research targets 4 potential stereotypes driving hostile attitudes and discriminatory behaviors toward pregnant women: incompetence, lack of commitment, inflexibility, and need for accommodation. We tested the relative efficacy of reducing concerns related to each of the stereotypes in a field experiment in which female confederates who sometimes wore pregnancy prostheses applied for jobs in a retail setting. As expected, ratings from 3 perspectives (applicants, observers, and independent coders) converged to show that pregnant applicants received more interpersonal hostility than did nonpregnant applicants. However, when hiring managers received (vs. did not receive) counterstereotypic information about certain pregnancy-related stereotypes (particularly lack of commitment and inflexibility), managers displayed significantly less interpersonal discrimination. Explicit comparisons of counterstereotypic information shed light on the fact that certain information may be more effective in reducing discrimination than others. We conclude by discussing how the current research makes novel theoretical contributions and describe some practical organizational implications for understanding and improving the experiences of pregnant workers.

    Full Text Available Abstract Background The World Health Organization endorses the use of artemisinin-based combination therapy for treatment of acute uncomplicated falciparum malaria in the second and third trimesters of pregnancy. However, the effects of pregnancy on the pharmacokinetics of artemisinin derivatives, such as artesunate (AS, are poorly understood. In this analysis, the population pharmacokinetics of oral AS, and its active metabolite dihydroartemisinin (DHA, were studied in pregnant and non-pregnant women at the Kingasani Maternity Clinic in the DRC. Methods Data were obtained from 26 pregnant women in the second (22 - 26 weeks or the third (32 - 36 weeks trimester of pregnancy and from 25 non-pregnant female controls. All subjects received 200 mg AS. Plasma AS and DHA were measured using a validated LC-MS method. Estimates for pharmacokinetic and variability parameters were obtained through nonlinear mixed effects modelling. Results A simultaneous parent-metabolite model was developed consisting of mixed zero-order, lagged first-order absorption of AS, a one-compartment model for AS, and a one-compartment model for DHA. Complete conversion of AS to DHA was assumed. The model displayed satisfactory goodness-of-fit, stability, and predictive ability. Apparent clearance (CL/F and volume of distribution (V/F estimates, with 95% bootstrap confidence intervals, were as follows: 195 L (139-285 L for AS V/F, 895 L/h (788-1045 L/h for AS CL/F, 91.4 L (78.5-109 L for DHA V/F, and 64.0 L/h (55.1-75.2 L/h for DHA CL/F. The effect of pregnancy on DHA CL/F was determined to be significant, with a pregnancy-associated increase in DHA CL/F of 42.3% (19.7 - 72.3%. Conclusions In this analysis, pharmacokinetic modelling suggests that pregnant women have accelerated DHA clearance compared to non-pregnant women receiving orally administered AS. These findings, in conjunction with a previous non-compartmental analysis of the modelled data, provide further evidence that

    Full Text Available The effects of chronic alcohol consumption during pregnancy were analysed in the gestation and offspring of alcoholized mice. Female C57BL/6J mice were placed overnight with stud males and the presence of a sperm plug in the next morning indicated the onset of gestation. Pregnant mice were distributed in two weight-matched groups. In the alcoholized group, the mice received a high protein liquid diet ad libitum containing 27.5% of ethanol-derived calories (5.28% v/v from gestation day 5 to 19. The control group received the same volume of diet containing isocaloric amounts of maltose-dextrin substituted for ethanol. After postnatal day zero, the dams received food pellets and tap water ad libitum. On postnatal day 6 the pups were counted and weighed at variable intervals up to the 60th day of life. The majority of the pregnant dams that have received ethanol completed the gestational period, and the chronic consumption of alcohol did not interfere with the number of dams that gave birth. The alcoholized and control dams gained an equivalent weight and consumed an equivalent volume of diet throughout the gestation. The number of pups from alcohol diet dams was 46,26% smaller compared with the control group. There were less male than female pups in the offspring of alcoholized mice. Teratogeny like gastroschisis and limb malformation were present in the offspring of alcoholized dams. The body weight of the offspring of alcoholized mice increased from the 18th to the 36th postnatal day.

    An oxidative burst occurs during pregnancy due to the large consumption of oxygen in the tissues and an increase in metabolic demands in response to maternal physiological changes and fetal growth. This study aimed to determine the oxidative profile and activity of δ-aminolevulinate dehydratase (δ-ALA-D) in pregnant women who received iron supplementation. Oxidative stress parameters were evaluated in 25 pregnant women with iron supplementation, 25 pregnant women without supplementation and 25 non-pregnant women. The following oxidative stress parameters were evaluated: thiobarbituric acid reactive substances (TBARS), protein thiol groups (P-SH), non-protein thiol levels (NP-SH), vitamin C levels, catalase and δ-ALA-D activity. Markers of oxidative stress and cell damage, such as TBARS in plasma were significantly higher in pregnant women without supplementation. Levels of P-SH, NP-SH and δ-ALA-D activity were significantly lower in pregnant women without supplementation compared to non-pregnant and pregnant women with supplementation, while vitamin C levels were significantly lower in pregnant women without supplementation when compared to non-pregnant women. The increase in the generation of oxidative species and decrease of antioxidants suggest the loss of physiological oxidative balance during normal pregnancy, which was not observed in pregnant women with iron supplementation, suggesting a protective effect of iron against oxidative damage.

    In the United States, eradication and reduction of vaccine-preventable diseases through immunization has directly increased life expectancy by reducing mortality. Although immunization is a public priority, vaccine coverage among adult Americans is inadequate. The Institute of Medicine, the Community Preventive Services Task Force, and other public health entities have called for the development of innovative programs to incorporate adult vaccination into routine clinical practice. Obstetrician-gynecologists are well suited to serve as vaccinators of women in general and more specifically pregnant women. Pregnant women are at risk for vaccine-preventable disease-related morbidity and mortality and adverse pregnancy outcomes, including congenital anomalies, spontaneous abortion, preterm birth, and low birth weight. In addition to providing direct maternal benefit, vaccination during pregnancy likely provides direct fetal and neonatal benefit through passive immunity (transplacental transfer of maternal vaccine-induced antibodies). This article reviews: 1) types of vaccines; 2) vaccines specifically recommended during pregnancy and postpartum; 3) vaccines recommended during pregnancy and postpartum based on risk factors and special circumstances; 4) vaccines currently under research and development for licensure for maternal-fetal immunization; and 5) barriers to maternal immunization and available patient and health care provider resources.

    Full Text Available This short story raises ethical issues about a woman’s request for medical assistance to get pregnant. In this fictional account, a 34-year-old woman has been trying to get pregnant for the last year. Her husband would like to keep trying for one more year, but the woman loses patience. She visits an ob-gyn and requests artificial insemination. She does not intend to tell her husband about this medical assistance. The doctor has helped single women, lesbian couples, and married couples with pregnancies, but he feels conflicted by this request. The doctor and the woman discuss their concerns and plans. Then they decide on a course of action. In a creative way, this story aims to bring to life ethical issues about assisted reproduction, complex relationships, individual choice, non- judgmental attitudes, deception, confidentiality, genetic connections, and social parents. But this story is not a textbook case that illustrates a clearly defined ethical issue. On the contrary, the story shows that some common ethical ideas don’t quite fit the characters’ experiences and the readers’ reactions.

To determine maternal hemoglobin behavior during pregnancy for middle altitude residents and to compare it with that reported in other populations with or without iron supplementation. Materials and methods. Hematological values from 227 pregnant women residing at 2 240 m altitude (Mexico City, with low obstetric and perinatal risk, and receiving supplementary iron, were compared with reference values obtained from other populations of pregnant women residing at different altitudes, after correcting for altitude. Results. While the hemoglobin values for the first and second trimester of pregnancy in our studied population were similar to those reported for iron-supplemented populations (p mayor que 0.05, the third trimester values were similar to those reported for a population without this supplement (p mayor que 0.05. Conclusions. Despite receiving supplementary iron, hemoglobin values during pregnancy from women residing at middle altitude show similar behavior to that reported for pregnant women without iron supplementation.

    Folic acid (FA) deficiency is associated with neural tube defects (NTD). In a non-risk pregnancy, The Danish National Board of Health recommends FA supplementation from planned pregnancy until three months after conception. We explored pregnant women's knowledge about and actual supplementation with FA and related this to education, number of pregnancies and age. Eighty-four consecutive pregnant women with a midwife consultation were included in the period 25-28 August 2008. All filled in a unified questionnaire. 82% had knowledge of FA supplementation and 89% received FA supplementation. 51% followed national recommendations. We found a statistically significant correlation between higher educational level and knowledge about FA supplementation, actual supplementation of FA and FA supplementation in accordance with national recommendations. No statistical associations were found between number of pregnancies or age and any FA-related parameters. Family, friends, general practitioner (GP) and the internet were the main information sources. Correct FA supplementation is quite low; conversely, knowledge about and actual FA supplementation are fairly high. Further intervention is necessary to increase the level of correct FA supplementation. Women with a low educational level--which may herald low socio-economic status--seem to form a suitable target group for information campaigns. Multiple pregnancies or higher age should not be perceived as indicators of a higher information level. Dissemination of information to the pregnant women including family, friends, GPs or the internet is recommended.

    We evaluated the effects of phenylalanine on reproductive performance and teratogenesis in mice, as well as we assessed its protective effect in mice treated with an acute dose of cyclophosphamide. Animals were divided into 6 experimental groups (females N = 15/group, males N = 5/group): G1, the negative control group, phosphate-buffered saline; G2, the positive control group, 35 mg cyclophosphamide/kg body weight (b.w.); G3 and G4 received phenylalanine at doses of 150 and 300 mg/ kg b.w., respectively; G5 and G6 received phenylalanine at doses of 150 and 300 mg/kg b.w. co-administered with cyclophosphamide at a dose of 35 mg/kg b.w., respectively. Pregnant mice received phenylalanine from 8-12 days of pregnancy and cyclophosphamide on the 10th day of treatment or the respective vehicles. In animals treated with cyclophosphamide, offspring fetal weight significantly decreased. The G5 and G6 groups, which received cyclophosphamide co-administered with phenylalanine, showed a smaller reduction in weight. Based on this analysis, the offspring from groups G2, G5, and G6 showed low weight due to pregnancy age. Moreover, at the doses used, phenylalanine did not interfere with embryo-fetal development. However, further studies are necessary to increase the understanding of the effects of phenylalanine on mouse reproductive performance and teratogenesis.

    Sulfamonomethoxine (SMM), a veterinary antibiotic, is widely used in China. However, the impacts of maternal SMM exposure on neurobehavioral development in early life remain little known. In this study, we investigated the effects of maternal SMM exposure during pregnancy on behavioral and physiological responses in offspring mice. Pregnant mice were randomly divided into three SMM-treated groups, namely low-(10mg/kg/day), medium-(50mg/kg/day), and high-dose (200mg/kg/day), and a control group. The pregnant mice in the SMM-treated groups received SMM by gavage daily from gestational day 1-18, whereas those in the control received normal saline. On postnatal day (PND) 50, spatial memory was assessed using the Morris water maze test, and anxiety was measured using the elevated plus-maze and open field tests. The results showed significantly increased blood glucose in pups whose mothers received a high SMM dose. In addition, maternal SMM exposure increased anxiety-related activities among the offspring; spatial learning and memory were impaired more severely in the male offspring. The contents of tetrahydrobiopterin (BH4) and brain-derived neurotrophic factors (BDNF) on PND 22 were significantly reduced in the male offspring of the high-dose group compared with the controls. These findings indicate that SMM may be identified as a risk factor for cognitive and behavioral development on the basis of gender and that it may be associated with diminished BH4 and BDNF levels early in life.

    Sedentary behavior has been associated with adverse health outcomes among pregnant women; however, few studies have characterized sedentary behavior patterns in this population. We described patterns of accelerometer-determined indicators of sedentary behavior among a national sample of US pregnant (n = 234) women and non-pregnant (n = 1146) women participating in the NHANES 2003-06 cycles. We included women with ≥ 4 days of accelerometer wear of ≥ 10 h/day. A count threshold of sedentary behavior as: 1) total accumulated sedentary time by bout length categories; 2) accumulated sedentary time within discrete bout length categories; 3) mean, median, and usual bout length; and 4) and bout frequency. Both non-pregnant and pregnant women spent up to 60% of their accelerometer wear time in sedentary behavior depending on the minimum bout threshold applied. Sedentary time was higher among pregnant women compared to non-pregnant women when lower bout thresholds (i.e. 10 min or less) were applied. The majority of total sedentary time was accumulated in bouts lasting sedentary bouts (i.e., ≥ 30 min) per day, which accounted for nearly 20% of total accumulated sedentary time. When applying a minimum threshold of at least 15 min, sedentary time increased across pregnancy trimesters, while sedentary time was similar across trimesters when using lower thresholds. These findings provide the first characterization of accelerometer-determined indicators of sedentary behavior in pregnant women. The minimum bout threshold applied influenced estimates of sedentary time and patterns sedentary time accumulation across pregnancy trimesters.

    Full Text Available I have been photographing my children, Eden and Emmanuelle since I got pregnant in 2003. I photograph as a mother, from a mother's point of view, showing the different aspects of motherhood as I see them; the beautiful and the ugly, the magic and the frustration, the extremes that live side by side when you are a mother. I try to photograph them all. Crying, sadness, anxiety, mourning the body I will never have again, the woman I will never be again. The strong physical connection to the children, erotic at times, something I found out many mothers experience but do not talk about much. With my images I try to sing a love song to my children, they are my inspiration. Their love, sadness, joy and neediness are for me the most meaningful moments of my life, the moments I want to photograph and preserve. Those images are taken from my life, they are very personal, they are about being a mother, being a child, the intensity of raising a child. This work is about the essence of being human.

    Full Text Available The effects of a protein-restricted diet (8% protein, 81% carbohydrate and 11% lipids on Schistosoma mansoni infectivity, fecal egg excretion and intestinal egg distribution in Swiss (SW mice were studied. Pregnant mice received a deficient diet from the middle of gestation until delivery. Seven-days-old mice were exposed to 50 cercariae (BH strain, Brazil. Offspring mice had a free access to the deficient diet since lactation until adulthood. The controls were fed with a commercial mice diet. A parasitological examination was performed between six and eight weeks post-infection while both groups were necropsied one week later. Mice on the experimental diet showed a significant loss in body weight. There was no significant difference (p > 0.05 in pre-patent period, kinetics of egg excretion and worm recovery from mice on either diet. Significant differences (p < 0.05 were found concerning to the percentage of deposited eggs in the distal segment of the small intestine from hosts on the experimental diet.Our data suggest that experimental malnutrition induced for a long term has no detrimental effect on the acute schistosomiais infection in SW mice.

    There is a widespread notion, based on limited information, that in areas of stable malaria transmission most pregnant women with Plasmodium falciparum infection are asymptomatic. This study aim to characterize the clinical presentation of malaria in African pregnant women and to evaluate the adequacy of case management based on clinical complaints. A hospital-based descriptive study between August 2003 and November 2005 was conducted at the maternity clinic of a rural hospital in Mozambique. All women attending the maternity clinic were invited to participate. A total of 2,330 women made 3,437 eligible visits, 3129 were analysed, the remainder were excluded because diagnostic results were unavailable or they were repeat visits. Women gave a standardized clinical history and had a medical exam. Malaria parasitaemia and haematocrit in capillary blood was determined for all women with signs or symptoms compatible with malaria including: presence and history of fever, arthromyalgias, headache, history of convulsions and pallor. Outcome measure was association of malaria symptoms or signs with positive blood slide for malaria parasitaemia. In 77.4% of visits pregnant women had symptoms suggestive of malaria; 23% (708/3129) were in the first trimester. Malaria parasitaemia was confirmed in 26.9% (842/3129) of visits. Headache, arthromyalgias and history of fever were the most common symptoms (86.5%, 74.8% and 65.4%) presented, but their positive predictive values for malaria parasitaemia were low [28% (27-30), 29% (28-31), and 33% (31-35), respectively]. Symptoms suggestive of malaria were very frequent among pregnant women attending a rural maternity clinic in an area of stable malaria transmission. However, less than a third of them were parasitaemic. In the absence of microscopy or rapid diagnostic tests, a large proportion of women, including those in the first trimester of gestation, would be unnecessarily receiving antimalarial drugs, often those with unknown

    Smoking is associated with multiple adverse pregnancy outcomes, including fetal growth restriction. The objective of this study was to determine whether cigarette smoke exposure during pregnancy in a mouse model affects the functional properties of maternal uterine, mesenteric, and renal arteries as a possible mechanism for growth restriction. C57Bl/CJ mice were exposed to whole body sidestream smoke for 4 h/day. Smoke particle exposure was increased from day 4 of gestation until late pregnancy (day 16-19), with mean total suspended particle levels of 63 mg/m(3), representative of moderate-to-heavy smoking in humans. Uterine, mesenteric, and renal arteries from late-pregnant and virgin mice were isolated and studied in a pressure-arteriograph system (n = 23). Plasma cotinine was measured by ELISA. Fetal weights were significantly reduced in smoke-exposed compared with control fetuses (0.88 +/- 0.1 vs. 1.0 +/- 0.08 g, P pregnant mice exposed to cigarette smoke during gestation. This difference was not apparent in isolated renal arteries from pregnant mice exposed to cigarette smoke; however, relaxation was significantly reduced in renal arteries from smoke-exposed virgin mice. In conclusion, we found that passive cigarette smoke exposure is associated with impaired vascular relaxation of uterine and mesenteric arteries in pregnant mice. Functional maternal vascular perturbations during pregnancy, specifically impaired peripheral and uterine vasodilation, may contribute to a mechanism by which smoking results in fetal growth restriction.

    The pregnant abdominal trauma patient presents a unique diagnostic challenge. This study aimed to evaluate the accuracy of abdominal sonography for the detection of clinically important injuries in pregnant abdominal trauma patients. A retrospective review was performed of a trauma center database from 2001 to 2011. Medical records were reviewed to determine initial abdominal imaging test results and clinical course. Sensitivity, specificity, positive predictive value, and negative predictive value of ultrasound for detection of traumatic injury were calculated. Of 19,128 patients with suspected abdominal trauma, 385 (2 %) were pregnant. Of these, 372 (97 %) received ultrasound as the initial abdominal imaging test. All 13 pregnant patients who did not receive ultrasound received abdominal CT. Seven pregnant patients underwent both ultrasound and CT. Seven ultrasound examinations were positive, leading to one therapeutic Cesarean section and one laparotomy. One ultrasound was considered false positive (no injury was seen on subsequent CT). There were 365 negative ultrasound examinations. Of these, 364 were true negative (no abdominal injury subsequently found). One ultrasound was considered false negative (a large fetal subchorionic hemorrhage seen on subsequent dedicated obstetrical ultrasound). Sensitivity and positive predictive value were 85.7 %. Specificity and negative predictive value were 99.7 %. Abdominal sonography is an effective and sufficient imaging examination in pregnant abdominal trauma patients. When performed as part of the initial assessment using an abbreviated trauma protocol with brief modifications for pregnancy, ultrasound minimizes diagnostic delay, obviates radiation risk, and provides high sensitivity for injury in the pregnant population.

    Genetic or nutritional disturbances in one-carbon metabolism, with associated hyperhomocysteinemia, can result in complex disorders including pregnancy complications and neuropsychiatric diseases. In earlier work, we showed that mice with a complete deficiency of methylenetetrahydrofolate reductase (MTHFR), a critical enzyme in folate and homocysteine metabolism, had cognitive impairment with disturbances in choline metabolism. Maternal demands for folate and choline are increased during pregnancy and deficiencies of these nutrients result in several negative outcomes including increased resorption and delayed development. The goal of this study was to investigate the behavioral and neurobiological impact of a maternal genetic deficiency in MTHFR or maternal nutritional deficiency of folate or choline during pregnancy on 3-week-old Mthfr(+/+) offspring. Mthfr(+/+) and Mthfr(+/-) females were placed on control diets (CD); and Mthfr(+/+) females were placed on folate-deficient diets (FD) or choline-deficient diets (ChDD) throughout pregnancy and lactation until their offspring were 3weeks of age. Short-term memory was assessed in offspring, and hippocampal tissue was evaluated for morphological changes, apoptosis, proliferation and choline metabolism. Maternal MTHFR deficiency resulted in short-term memory impairment in offspring. These dams had elevated levels of plasma homocysteine when compared with wild-type dams. There were no differences in plasma homocysteine in offspring. Increased apoptosis and proliferation was observed in the hippocampus of offspring from Mthfr(+/-) mothers. In the maternal FD and ChDD study, offspring also showed short-term memory impairment with increased apoptosis in the hippocampus; increased neurogenesis was observed in ChDD offspring. Choline acetyltransferase protein was increased in the offspring hippocampus of both dietary groups and betaine was decreased in the hippocampus of FD offspring. Our results reveal short-term memory

    Asymptomatic bacteriuria is the significant presence of bacteria in urine of an individual without symptoms. The aim of the study is to determine the prevalence of asymptomatic bacteriuria in pregnant women. This study was a prospective study conducted in the department of Obstetrics and Gynaecology at B. P. Koirala Institute of Health Sciences. The duration of the study was six months from January to June 2012. A total of 600 pregnant women were enrolled. All women were clinically identified to have no signs and symptoms of UTI. Clean catch midstream urine sample was collected from each patient into a sterile vial. The urine samples were examined for microscopic and culture sensitivity test. Out of 600 pregnant women, 52 were positive for significant bacteriuria with a prevalence rate of 8.7%. There was a significant difference in prevalence of asymptomatic bacteriuria with respect to trimester (p=0.005). Age did not show any significant difference in the prevalence of asymptomatic bacteriuria (p=0.807). There was not any significant difference in the prevalence of asymptomatic bacteriuria with respect to parity (p=0.864) and booking status (p=0.397). Escherichia coli (35%), Acinetobacter species (15%), Enterococcus species (12%) and Klebsiella pneumoniae (10%) were the common isolates. Most of the isolates were sensitive either to Nitrofurantoin, Norfloxacin or Amikacin. Asymptomatic bacteriuria is common in pregnancy. Urine culture sensitivity should be carried out routinely on all pregnant patients in order to prevent the dangerous complications associated with it.

    Pregnancy in rabbits alters the reactivity of the tissues to the virus of infectious myxomatosis. The livers of pregnant animals with the myxoma have a central acidophilic necrosis. Secondary lesions in the lungs are much more numerous and larger in the pregnant than in the non-gravid animals. In like manner the lesions in the spleen are more extensive in the pregnant rabbit. On the other hand the skin lesions of the pregnant animal are decreased in size. PMID:19870088

    Cigarette smoking is prevalent in pregnant substance users but receives low priority in substance use disorder treatment. This article reports the results of a secondary analysis of a randomized, multisite trial with 200 pregnant substance users, 145 (72.5%) of whom smoked at baseline. As predicted: (1) smokers had significantly greater substance use; (2) approximately half of smokers wanted to quit; and (3) smokers with a quit goal had significantly greater self-efficacy and lower perceived difficulty of quitting. Smoking may be associated with more severe substance use in pregnant substance-using patients, half of whom may be interested in smoking-cessation interventions.

Statistical Analysis: Proportions and Chi-square Test Results: Most of the pregnant women (92.31% were registered for antenatal care, but only 30.00% of them were registered in the 1st trimester of pregnancy. As regards to TT immunization, 70.77% of the pregnant women had received 2 doses or 1 booster dose. Iron and Folic Acid supplementation was taken by 59.68% of the pregnant women. Nearly 39.52 % of pregnant women were provided with full antenatal care. The main antenatal care provider for pregnant women was doctor (64.52%. The provision of full antenatal care package was found to be significantly higher among the pregnant women belonging to social classes I and II and in those who have studied above SSLC. Conclusion: The study shows early and wide spread use of antenatal care, but it also reveals that the antenatal visits occur late in the pregnancy. The literacy of women has significant bearing on utilization of antenatal care by the pregnant women.

    Background and Objective: Vitamin D deficiency during pregnancy is a worldwide problem. Studies have reported prevalence ranged 18-84% in pregnant women. Receiving adequate calcium and vitamin D during pregnancy period is necessary for calcium homeostasis, fetal growth and bone mineralization. This study was aimed to determine the prevalence of vitamin D deficiency in pregnant women and their neonates in Shahroud city in the northeast Iran. Methods: In this cross-sectional study, 284 pregnant women and their neonates referred to Fatemiyeh Hospital of Shahroud were included. Blood samples of mothers and umbilical cords were collected during the delivery and were sent to laboratory in order to measure calcium and 25-hydroxy vitamin D. Findings: Amounts of Vitamin D insufficiency (20-30 ng/mL) and deficiency (vitamin D (r=0.12, p=0.053). Conclusion: More than half of the mothers and their neonates had some degrees of vitamin D deficiency. It is recommended to evaluate the nutritional status of vitamin D in pregnant women along with public health interventions to be carried out. PMID:27157170

    Full Text Available Objective: To evaluate the association between perceived social support and anxiety disorders in pregnant adolescents. Methods: We conducted a cross-sectional study with a sample of 871 pregnant women aged 10 to 19 years who received prenatal care in the national public health care system in the urban area of Pelotas, state of Rio Grande do Sul, southern Brazil. We assessed perceived social support and anxiety disorders using the Medical Outcomes Study Social Support Survey and the Mini International Neuropsychiatric Interview. A self-report questionnaire was used to obtain sociodemographic information. Results: The prevalence of any anxiety disorder was 13.6%. Pregnant adolescents with an anxiety disorder reported less perceived social support in all domains (affectionate, emotional, tangible, informational, and positive social interaction. Older teenagers reported lower perceived support in the emotional, informational, and positive social interaction domains, whereas those with low socioeconomic status reported lower perceived social support in the material domain. Women who did not live with a partner had less perceived social support in the affectionate and positive social interaction domains. Conclusion: Perceived social support seems to be a protective factor against anxiety disorders in pregnant adolescents, with a positive effect on mental health.

    Paracoccidioidomycosis (PCM), caused by the dimorphic fungus Paracoccidioides brasiliensis (Pb), is the most prevalent systemic mycosis in Latin America. There are few reports in the literature about the disease damages during pregnancy and the consequences to the fetuses and breeding. This study evaluated the implications of PCM during pregnancy on offspring and mothers in Wistar rats. Groups of rats were submitted to systemic Pb infection, by intraperitoneal infusion, and mated 30 days after the infection date. Immediately after birth, rats and neonates were sacrificed to obtain organs for standard histological examination, morphometric analysis, fungi recovery by plating (CFU) and dosing of anti-Pb antibodies by ELISA. There were no stillbirths or miscarriages, however, the fetuses from infected pregnant rats had lower body and organ weight but the fertility rate was 100%. The largest number of CFU was recovered from the organ of pregnant rats, the pathological examination revealed more severe infection in the same group, further on the largest number of granulomas and fungal field. It can be concluded that the PCM was more severe in the group of pregnant rats, with implications to the weight of offspring. PMID:27049707

    Full Text Available Background: Asymptomatic bacteriuria is the significant presence of bacteria in the urine of an individual without symptoms. In pregnancy, the apparent reduction in immunity of pregnant women tends to encourage the growth of pathogens. Aim: This study was carried out to determine the prevalence of asymptomatic bacteriuria in pregnant women attending a primary health centre in Benin City, Nigeria. Materials and Methods: A total of 1,228 pregnant women were recruited for this study. All subjects were clinically identified to have no signs and symptoms of UTI. Clean catch midstream urine sample was collected from each patient into sterile universal container. The urine samples were examined microscopically and by cultural method. Identification of isolates was by standard microbiological technique. Result: A total of 556 (45.3% were positive for significant bacteriuria. There was a significant difference in the prevalence of asymptomatic bacteriuria with respect to age (P < 0.0001. Trimester did not show any significant difference (P = 0.2006 in the prevalence of asymptomatic bacteriuria. Escherichia coli was the most predominant organism followed closely by Staphylococcus aureus. Ciprofloxacin, Ceftriaxone and Augmentin were found to be the most effective antibiotics against the urinary isolates. Conclusion: Asymptomatic bacteriuria is not uncommon among antenatal patients in the population studied. Routine urine cultural test should be carried out on all antenatal patients in order to identify any unsuspecting infection.

    2015-10-01

    As use of imaging in the evaluation of pregnant and lactating patients continues to increase, misperceptions of radiation and safety risks have proliferated, which has led to often unwarranted concerns among patients and clinicians. When radiologic examinations are appropriately used, the benefits derived from the information gained usually outweigh the risks. This review describes appropriateness and safety issues, estimated doses for imaging examinations that use iodizing radiation (ie, radiography, computed tomography, nuclear scintigraphy, and fluoroscopically guided interventional radiology), radiation risks to the mother and conceptus during various stages of pregnancy, and use of iodinated or gadolinium-based contrast agents and radiotracers in pregnant and lactating women. Maternal radiation risk must be weighed with the potential consequences of missing a life-threatening diagnosis such as pulmonary embolus. Fetal risks (ie, spontaneous abortion, teratogenesis, or carcinogenesis) vary with gestational age and imaging modality and should be considered in the context of the potential benefit of medically necessary diagnostic imaging. When feasible and medically indicated, modalities that do not use ionizing radiation (eg, magnetic resonance imaging) are preferred in pregnant and lactating patients. Radiologists should strive to minimize risks of radiation to the mother and fetus, counsel patients effectively, and promote a realistic understanding of risks related to imaging during pregnancy and lactation.

  1. Craving and Withdrawal Symptoms During Smoking Cessation: Comparison of Pregnant and Non-Pregnant Smokers.

    2016-04-01

    Although pregnant smokers are aware of the negative peri- and postnatal health consequences of smoking, the cessation rate in pregnancy is low, raising the question of why pregnant smokers have difficulty quitting. Reasons might be that pregnant smokers experience more intense craving and withdrawal symptoms than non-pregnant smokers. We compared craving and withdrawal in 306 pregnant smokers versus 93 non-pregnant women using data from two smoking cessation trials. Complete data were analyzed using pre-quit and post-quit (2 weeks after quit date) craving and withdrawal measured by the 12-item French Tobacco Craving Questionnaire (FTCQ-12) and French Minnesota Nicotine Withdrawal Scale (FMNWS). Pregnant smokers started smoking and smoked regularly earlier and succeeded far less at quitting smoking by week 2 than the general population of smokers (11% versus 43%). Post-quit date FTCQ-12 general score was higher in pregnant smokers compared to comparison groups, and was driven by elevated emotionality and expectancy. FMNWS decreased significantly less among pregnant smokers than among non-pregnant smokers. Insufficient reduction of craving and withdrawal symptoms in response to a quit attempt may partially explain why pregnant smokers may have more difficulty quitting than non-pregnant smokers. Because this was a historical comparison, findings are preliminary; however, they might foster further investigation of differences in craving and withdrawal symptoms in pregnant versus non-pregnant smokers.

    BACKGROUND: Pregnant women were suspected to be at particular risk when H1N1pnd09 influenza became pandemic in 2009. Our primary objective was to compare the immune responses conferred by MF59®-adjuvanted vaccine (Focetria®) in H1N1pnd09-naïve pregnant and non-pregnant women. The secondary aims...... women after gestational week 20: (1) 7.5 µg H1N1pnd09 antigen with MF59-adjuvant (Pa7.5 µg); (2) 3.75 µg antigen half MF59-adjuvanted (Pa3.75 µg); (3) 15 µg antigen unadjuvanted (P15 µg); and in non-pregnant women receiving (4) 7.5 µg antigen full adjuvanted (NPa7.5 µg). Blood samples were collected......-pregnant (NPa7.5 µg) groups (OR = 0.49 [0.13-1.85], p = 0.29). CONCLUSION: Our study suggests the immune response to the 7.5 µg MF59-adjuvanted Focetria® H1N1pnd09 vaccine in pregnant women may be diminished compared with non-pregnant women.

    Document and analyze Ecuador's experience using active community case-finding for uptake of pregnant and postpartum women in Ecuador. A cross-sectional descriptive study was conducted of information obtained on active community case-finding of pregnant and postpartum women in the catchment areas of 200 primary care facilities of Ecuador's Ministry of Public Health. Visits were made to 460 451 homes in 20 provinces; 15 622 pregnant women and 4 014 postpartum women were identified. Of the pregnant women, 89% (13 875) had had at least one prenatal check-up, while 70% of postpartum women (4 014) had had at least one post-delivery or post-caesarean check-up. Potential risk was identified in 29% of pregnant women (4 601). Orellana and Sucumbíos provinces had the lowest percentages of pregnant women with at least one prenatal check-up and the lowest percentages of postpartum women with at least one postpartum checkup. A total of 3 951 brigades were formed at the national level for this activity. Active community case-finding was valuable in identifying pregnant and postpartum women who had not been captured by the health system, especially to detect their risk status, in addition to the advantages of participatory uptake, especially with support from universities with health majors. Low coverage for postpartum check-ups underscores the importance of learning why women do not receive this care. Similar experiences need to be systematized to improve the process.

    Identify health-worker barriers that keep pregnant women who receive prenatal care from being screened for syphilis (Los Andes Health Network, Bolivia). Semi-structured interviews were done with 46 health care providers and 249 clinical health records of pregnant women were analyzed in eight public health facilities in the Los Andes network. Health-worker barriers to syphilis screening in pregnant women included lack of time by personnel to raise awareness of the benefit of syphilis screening; some mentioned that syphilis tests should only be done in facilities that attend deliveries and have a laboratory; lack of communication between clinicians and laboratory personnel; and problems with provision of supplies and reagents. The clinical record review found that only 55.4% contained syphilis laboratory results and only 37.4% of perinatal clinical histories had records of laboratory results. The interviews found that providers believe that syphilis screening is done in 100% of pregnant women receiving prenatal care. Syphilis screening is not being done according to Bolivia's strategy for the elimination of congenital syphilis, and is not done on more than half of pregnant women in prenatal care with perinatal clinical history records. This is not perceived by health professionals and can become a barrier to syphilis screening in pregnant women.

    Full Text Available Aim: Carbamazepine (CBZ is an anticonvulsant medication that can produce congenital anomalies. This study aimed to assess protective role of aqueous jujube extract (JE on CBZ induced congenital anomalies in mice fetuses. Methods:One hundred pregnant Balb/c mice were divided into 8 experimental (E and 2 control (C groups equally. The groups (E1, E5, E6 and (E2, E7, E8 received 50 and 100 mg/kg of CBZ, respectively IP, from GD 0 to GD15. Besides, groups (E5, E7 and (E6, E8 in addition to CBZ, were treated with 200 and 400 mg/kg JE, respectively from ten days prior to gestation, till GD15. The groups E3 and E4 received only 200 and 400 mg/kg of JE respectively. The control groups (C1, C2 received normal saline and tween-20 in turn. On GD18 dams cesarianed and their fetuses assessed for skeletal anomalies by using Alizarin red-alcian blue staining. Results:CBZ induced various anomalies such as; limb defects, craniofacial malformations and etc in mice fetuses. However, these anomalies significantly decreased in groups which were co-administered with CBZ and JE. Conclusion: Co-administration of JE and CBZ significantly decrease teratogenicity of CBZ. Therefore, JE may play a protective role against those properties of CBZ inducing teratogenicity

    2014-01-01

    Multiple-input multiple-output (MIMO) systems can increase the spectral efficiency in wireless communications. However, the interference becomes the major drawback that leads to high computational complexity at both transmitter and receiver. In particular, the complexity of MIMO receivers can be prohibitively high. As an efficient mathematical tool to devise low complexity approaches that mitigate the interference in MIMO systems, lattice reduction (LR) has been widely studied and employed over the last decade. The co-authors of this book are world's leading experts on MIMO receivers, and here they share the key findings of their research over years. They detail a range of key techniques for receiver design as multiple transmitted and received signals are available. The authors first introduce the principle of signal detection and the LR in mathematical aspects. They then move on to discuss the use of LR in low complexity MIMO receiver design with respect to different aspects, including uncoded MIMO detection...

  12. Use of a Th1 Stimulator Adjuvant for Vaccination against Neospora caninum Infection in the Pregnant Mouse Model

    Directory of Open Access Journals (Sweden)

    Denis Grandgirard

    2013-03-01

    Full Text Available Vertical transmission from an infected cow to its fetus accounts for the vast majority of new Neospora caninum infections in cattle. A vaccine composed of a chimeric antigen named recNcMIC3-1-R, based on predicted immunogenic domains of the two microneme proteins NcMIC1 and NcMIC3, the rhoptry protein NcROP2, and emulsified in saponin adjuvants, significantly reduced the cerebral infection in non-pregnant BALB/c mice. Protection was associated with a mixed Th1/Th2-type cytokine response. However, the same vaccine formulation elicited a Th2-type immune response in pregnant mice and did not prevent vertical transmission or disease, neither in dams nor in offspring mice. In this study, an alternative vaccine formulation containing recNcMIC3-1-R emulsified in Freund’s incomplete adjuvant, a stimulator of the cellular immunity, was investigated. No protection against vertical transmission and cerebral infection in the pregnant mice and a very limited protective effect in the non-pregnant mice were observed. The vaccine induced a Th1-type immune response characterized by high IgG2a titres and strong IFN-γ expression, which appeared detrimental to pregnancy.

    This pilot study examined the effectiveness of an Aquatic Exercise Program (AEP) provided by an occupational therapist for pregnant women on hospitalized bed rest. Researchers conducted a retrospective analysis of medical records of hospitalized pregnant women comparing those who attended an AEP (n = 19) to a control group who received no AEP (n = 12). Statistical tests were used to assess evidence of differences in length of gestation as well as blood pressure and amniotic fluid index (AFI) at discharge. Women who received an AEP had increased AFI and length of gestation compared to the control group. This study supports the use of an AEP as an intervention for pregnant women on prescribed bed rest. Further research is recommended to validate these findings with a larger sample.

    Sugammadex has been shown to decrease the efficiency of progesterone-containing oral contraceptive drugs which possess a steroid structure. The aim of the present study was to evaluate the effects of sugammadex on progesterone levels in pregnant rats as well as on the physiological course of the pregnancy. Animal experiment. This study was approved by the Selçuk University Ethical Committee for Experimental Animal Research. Pregnant Winster Albino rats (n=26) were divided into three groups and administered with various intravenous injections on the 7(th) day of pregnancy. The control group (Group K, n=6) received 1.5 mL serum physiologic, the sugammadex group (Group S, n=10) received 30 mg/kg sugammadex and the sugammadex + rocuronium group (Group SR, n=10) received 30 mg/kg sugammadex and 3.5 mg/kg rocuronium. Progesterone levels were measured and the offspring were monitored for morphologic status. Mean progesterone levels were 94.16±15.54 ng/mL in Group K, 87.86±12.48 ng/mL in Group S, and 94.53±16.10 ng/mL in Group SR (p>0.05). No stillbirth or miscarriage was observed in the rats. The mean number of offspring was 6.8±1.47 in Group K, 6.5±1.35 in Group S, and 6.4±1.17 in Group SR. The offspring appeared macroscopically normal. Sugammadex does not appear to affect the progesterone levels in pregnant rats in the first trimester and the clinical course. Successful completion of pregnancy and the absence of stillbirth or miscarriage will guide future studies about the use of sugammadex, particularly in the first trimester of the pregnancy.

    Sentinel lymph node biopsy (SLNB) is currently not recommended in pregnant patients with breast cancer due to radiation concerns. Twelve pregnant patients with breast cancer received low-dose (10 MBq on average) lymphoscintigraphy using {sup 99m}Tc human serum albumin nanocolloids. The sentinel lymph node (SLN) was identified in all patients. Of the 12 patients, 10 had pathologically negative SLN. One patient had micrometastasis in one of four SLN. One patient had metastasis in the SLN and underwent axillary clearance. From the 12 pregnancies, 11 healthy babies were born with no malformations and normal weight. One baby, whose mother underwent lymphatic mapping during the 26th week of gestation, was operated on at the age of 3 months for a ventricular septal defect and at 43 months was in good health. This malformation was suspected at the morphological US examination during week 21, well before lymphoscintigraphy, and was confirmed a posteriori by a different observer based on videotaped material. No overt axillary recurrence appeared in the patients with negative SLNs after a median follow-up of 32 months. Our experience supports the safety of SLNB in pregnant patients with breast cancer, when performed with a low-dose lymphoscintigraphic technique. (orig.)

    Micronutrients or trace elements are minerals essential for growth and development of the body human. To analyze changes in normal pregnancy and during preeclampsia, serum iron and its main proteins: ferritin and soluble transferrin receptors. This is a prospective study of case- control study of 56 pregnant women and 30 non-pregnant women selected as controls. Pregnant women received a quarterly dosing paramètres. The same assays were performed once in controls. The comparative assay of various parameters in normal pregnancy and in control women showed a significant decrease in serum iron from 1 to the third quarter, a slight decline in reserves ferritin in 1st and 2nd quarter increases and becomes significant in the third quarter and an increase of soluble receptors trasferrine during pregnancy, which becomes significant in the third quarter. We noted a disturbance of these parameters in preeclampsia. Iron is essential for fetal development. His involvement in several maternal- fetal complications is not to dismantle .

    Fifty years ago, when a woman became pregnant, she was expected to stop working. Today, however, most women who work are the primary, sole, or co-breadwinner for their families, and their earnings during pregnancy are often essential to their families' economic well-being. Medical data about working during pregnancy are sparse but generally show that both low-risk and high-risk women can tolerate work-related duties well, although some work accommodations (eg, providing a chair for sitting, allowing snacks, or modifying the work schedule) may be necessary. However, some employers refuse to accommodate pregnant women who need adjustments. This can result in a woman being forced to make the choice between working without accommodations and losing her income and health insurance or even her job. Prenatal care providers can play an important role by implementing changes in their own practice, shaping public policy, and conducting research to increase protections for pregnant women and to ensure that they receive medically recommended accommodations while continuing to earn income for their growing families.

    Bacterial products are thought to induce labor by stimulating the production of pro-inflammatory cytokines and prostaglandins in gestational tissues, leading to the onset of preterm parturition. Progesterone withdrawal is a prerequisite of parturition in many species. Yet a role for progesterone in the mechanisms responsible for preterm parturition, in the setting of infection, is unclear. The current studies were conducted to determine if a fall in serum progesterone concentrations occurs before the onset of bacterial product-induced preterm parturition in animals. Accordingly, pregnant mice at day 15 (70% gestation) were injected i.p. with Escherichia coli lipopolysaccharide (LPS; 50 microg/mouse) and timed-pregnant rabbits were inoculated transcervically with a suspension of E. coli to cause an ascending intrauterine infection. Control animals in both groups received equal volumes of sterile phosphate-buffered saline (PBS) solution. Blood specimens were collected at regular intervals and serum progesterone levels were determined by RIA. Within 14 h of LPS administration, mice delivered their pups. The median concentrations of serum progesterone were significantly lower at 1 h, 4 h, 10 h, and at the onset of preterm parturition (11-12 h) after LPS injection, compared to that in animals given PBS. Similarly, E. coli-inoculated rabbits delivered 1-2 days posttranscervical inoculation and demonstrated 60% decrease in serum progesterone within 12-24 h of inoculation compared to those given PBS. Parturition in both control groups occurred at term, following typical progesterone withdrawal. It is concluded that LPS administration to pregnant mice and ascending intrauterine infection in pregnant rabbits is associated with a dramatic fall in serum progesterone concentrations prior to the onset of parturition.

    A differentiated administration of calcium antagonists in preoperative preparation of pregnant patients with hypertension enabled the conversion of circulatory system state to "normal pregnancy range": a conversion of hypokinetic (including the HES solution infusion) and hyperkinetic types of haemodynamics to eukinetic one, with the decrease of total peripheral resistance and myocardium need for oxygen, autonomous nervous system state to physiological sympathicotonia. Evidence shows that continued intra-operative treatment including tranexamic acid enables to maintain those results during the surgery. In postoperational period, the clinical manifestations of SIRS in patients who has received the mentioned therapy were marked less then in control group, and the newborns have a higher Apgar score.

    To compare vaginal colonization by genital micoplasmas in pregnant and non pregnant women and to determine the association between pregnancy and colonization by these microorganisms, samples of exocervix an endocervix from pregnant (n = 80) and non pregnant (n = 65) women, from two health centers of Maracaibo, Zulia State, Venezuela were processed. The Mycoplasma-Lyo kit (bioMérieux laboratories) was used for the culture and identification of genital micoplasmas. In pregnant women, prevalences of 10% for M. hominis and 26.25% for Ureaplasma spp. were found; 35.38% for M. hominis and 20% for Ureaplasma spp. in non-pregnant, were obtained. Among the pregnant, Ureaplasma spp. was the most frequently isolated micoplasma, in symptomatic and asymptomatic; while in the non pregnant group, M. hominis was more common among the symptomatic patients; only one case (1.54%) was an asymptomatic carrier of Ureaplasma spp. The highest positivity percentages were obtained in primigravidas (48.71%) and during the second gestational trimester (34.21%). No statistically significant differences were found between vaginal colonization by genital micoplasmas according to age, number of pregnancy and gestational trimester; but they were found between the presented symptomatology and vaginal colonization by genital micoplasmas. Genital micoplasmas were isolated from gravid women at approximately the same recovery rate as in non-pregnant women; being M. hominis the most frequently isolated in non-pregnant women and Ureaplasma spp. in the pregnant group.

    Ultrasonography is frequently used to diagnose acute appendicitis in women of reproductive age, but its diagnostic value in pregnant patients remains unclear. This study sought to compare the diagnostic performance of ultrasound in pregnant and young nonpregnant women with suspected acute appendicitis. The database of a single tertiary medical center was reviewed for all women of reproductive age who underwent appendectomy either during pregnancy (2000-2014) or in the nonpregnant state (2004-2007) following ultrasound evaluation. The performance of ultrasound in terms of predicting the final pathologic diagnosis was compared between the pregnant and non pregnant groups using receiver operating characteristic curve analysis. Of 586 young women treated for appendicitis during the study periods (92 pregnant, 494 non-pregnant), 200 underwent preoperative ultrasound [67 pregnant, and 133 nonpregnant young women]. The pregnant and nonpregnant groups were comparable in age and presenting symptoms. There was no significant difference in the predictive performance of ultrasound between the two groups (AUC 0.76 and 0.73 respectively, p = 0.78) or within the pregnant group, by trimester [first (n = 23), AUC 0.73; second (n = 32), AUC 0.67; third (n = 12), AUC 0.86; p = 0.4]. Ultrasound had a positive predictive value of 0.94 in the pregnant group and 0.91 in the nonpregnant group; corresponding negative predictive values were 0.40 and 0.43. There appears to be no difference in the ability of ultrasound to predict the diagnosis of acute appendicitis between pregnant women and nonpregnant women of reproductive age. Therefore, similar preoperative imaging algorithms may be used in both patient populations. Copyright © 2016 IJS Publishing Group Ltd. Published by Elsevier Ltd. All rights reserved.

    The vascular addressins mucosal addressin cell adhesion molecule-1, P-selectin and ICAM-1 permit alpha(4)beta(7)-integrin-expressing DC, especially those of the myeloid lineage (CD11c(+)CD11b(+) DC), to access the pregnant mouse uterus. Injection of blocking monoclonal antibodies against mucosal addressin cell adhesion molecule-1 in P-selectin(-/-) mice or experimental approaches with beta7-integrin(-/-) or ICAM-1(-/-) mice revealed that limited access or absence of CD11c(+)CD11b(+) DC at the maternal/fetal interface negatively affects the frequency, size and functional properties of uterine NK (uNK) cells. Adoptive transfer of DC obtained from WT mice into beta7-integrin(-/-) mice abrogates these effects and emphasizes the importance of DC in uNK cell differentiation. Interestingly, those implantation sites lacking CD11c(+)CD11b(+) DC are characterized by decreased IL-15 and IL-12 mRNA and/or protein levels. Chronic administration of IL-15 in these mice gives rise to uNK cell numbers and size comparable to those of WT mice, whereas additional injection of IL-12 positively affects the IFN-gamma expression of uNK cells. Real-time RT-PCR and protein arrays performed with isolated uterine DC underline the role of DC as a source of IL-15 and IL-12 in the pregnant mouse uterus.

    To investigate the effects of the maternal caffeine consumption during pregnancy to adult male testis mice offspring. Twenty pregnant mice were divided into control group (c) and caffeine group (cf). dams received daily saline or 20 mg/kg of caffeine subcutaneously. Male offspring were monitored daily until 13th week. The testis were used to evaluate both the proliferation (pcna) and apoptosis (bax); leptin receptor (ob-r); aromatase; follicle stimulating hormone (fshr), luteinizing hormone (lhr) and androgen receptors (ar); steroidogenic acute regulatory protein (star); vascular endothelial growth factor (vegf) and estrogen receptors (erα and erβ) by western blotting. Serum concentrations of testosterone, estradiol and leptin were measured. There was a significant reduction in food intake and the body mass gain (pcaffeine. The serum testosterone levels in the cf offspring were 90% lower than in the c offspring (p=0.04). Maternal caffeine consumption has a role and alters the testis of the offspring in adulthood.

    Full Text Available A convincing number of epidemiological studies have reported on the exposure to and consequences of organophosphorus compounds (OPCs in pregnant women. However, there is still a knowledge gap and paucity of systematic literature from animal studies. This study was undertaken with the hypothesis that short-duration sublethal exposure to OPCs can produce maternal and fetal lethal effects as chronic exposure. This study examineses the teratogenicity and embryotoxicity of paraoxon (POX in mice at a dose that is non-lethal to non-pregnant mothers. Pregnant mice were injected intraperitoneally (i.p. with paraoxon (50 nmol/mouse on the 4th and 5th days of gestation, and the effect of the treatment was assessed on day 18 of gestation. This dose was fatal to pregnant mice in 21% of instances as compared to non-pregnant animals in which 0% mortality was detected, even after daily injection of a similar dose for five days. Significant inhibition of red blood cell acetylcholinesterase (RBC-AChE was observed in pregnant mice as compared to non-pregnant ones; however, no apparent neuronal effect was detected. Of note were fetal weight decrement, pregnancy termination, intrauterine growth retardation and maternal death. We concluded that exposure to even a non-toxic dose might be critical for pregnant mothers, the pregnancy as well as fetuses. In addition, even exposure of short duration can be detrimental and capable of producing profound and fatal effects.

    The physiology and anatomy of pregnant women change during pregnancy. Pregnancy is an anatomically and physiologically amended process experienced by women and as a result of these changes, sexual life of pregnant women alters during pregnancy. We aimed to compare sexual functions of pregnant and non-pregnant women. Sexually active 246 pregnant women were included into this cross-sectional controlled study. A total of 210 non-pregnant women were served as control. Both groups were compared in terms of age, gestational age, presence of urinary incontinence, body mass index, and obstetrical history. Sexual functions of the women were evaluated with Female Sexual Function Index (FSFI). Data were analyzed using chi-square, Mann-Whitney U, Fisher's Exact, Shapiro Wilk, Kruskal Wallis and Dunnett's tests where appropriate. The Pvalues < .05 were considered statistically significant. Mean age in both groups were comparable (P = .053). Median total FSFI scores in the pregnant women were significantly lower than those non-pregnant (18.9 vs. 22.7; P < .05). Additionally, the subgroup analyses of the FSFI scores were found that, total FSFI score is significantly lower in the pregnant group compared to non-pregnant group (P < .05). Furthermore, rate of sexual dysfunction in pregnant women was significantly higher than those non-pregnant women (91.08% vs. 67.61%, P = .0001). However, in pregnant women, no meaningful difference in rate of sexual dysfunction was found according to the trimesters (P = .632). Moreover, gravidity and parity exhibited negative impacts on the sexual functions. But number of abortions did not affect sexual function. These data demonstrate that pregnancy significantly diminishes sexual function in women. We believe that, couples need to be counseled regarding the impact of pregnancy on sexual functions.

    Syphilis is a preventable cause of foetal loss and congenital disease. Although the VDRL test is an integral part of routine antenatal care in India, little is known about the disease burden in pregnancy in India. Therefore, we carried out a study to determine the prevalence of VDRL positivity and syphilis among pregnant women in Vellore and to audit the management and outcome of VDRL-positive pregnancies. A retrospective review of case records. Only 0.98% of pregnant women were positive by the VDRL test. However, foetal loss occurred in 16 (32%) of the 50 seropositive women; 15 of these did not receive antenatal care. Seventeen of the 34 seropositive multiparous women had had previous foetal losses. Only 16 women had received penicillin. Although the seroprevalence of syphilis in pregnancy is low, it is an unrecognized cause of foetal loss in Vellore. An audit of the testing and management of VDRL positivity in pregnancy provides valuable information on the quality of antenatal care in an area.

    The present study was undertaken to investigate the pharmacokinetics of metronidazole in pregnant patients with bacterial vaginosis. Twenty patients received metronidazole (Flagyl ®, Pfizer, 235 East 42nd Street, NY, NY 10017) oral dose 500 mg twice a day for 3 consecutive days. Pharmacokinetic analyses of metronidazole were performed after a single oral dose on the morning of day 4. Although absolute estimates of metronidazole total body exposure were highest in women during early term pregnancy, weight-corrected estimates of exposure maximum plasma drug concentration (C(max)) and the area under the plasma concentration-versus-time curve (AUC(0-12)), along with apparent oral clearance and distribution volume, were not significantly different between women at early, middle, and late stages of pregnancy and were in the range of reported values for nonpregnant patients receiving a similar dose. The pharmacokinetic profile of metronidazole did not change at the different time points assessed during pregnancy.

    2015-01-01

    This book demonstrates how to design a wideband receiver operating in current mode, in which the noise and non-linearity are reduced, implemented in a low cost single chip, using standard CMOS technology.  The authors present a solution to remove the transimpedance amplifier (TIA) block and connect directly the mixer’s output to a passive second-order continuous-time Σ∆ analog to digital converter (ADC), which operates in current-mode. These techniques enable the reduction of area, power consumption, and cost in modern CMOS receivers.

    1984-01-01

    The incidence of bacterial colonization and risk of infection associated with the use of continuous insulin infusion pump (CIIP) was examined in 11 pregnant diabetic patients. All patients received instruction on specific aspects of CIIP and needle insertion technique according to the protocol used in our institution. A total of 220 cultures was performed on the subcutaneous needle and connective tubing. There was no clinical evidence of infection. In conclusion, the risk of infectious cutaneous complications in the pregnant diabetic patient using CIIP is not increased over the nonpregnant diabetic population.

    To investigate the prevalence of human papillomavirus (HPV) in cervical samples of pregnant and non-pregnant women in South-Brazil. A prospective study of 91 pregnant and 92 non-pregnant women with no previous history of cervical dysplasia or cancer was carried out. Cervical samples for HPV testing and cytology were collected in each trimester of pregnancy and in the puerperium for pregnant women and at matched intervals for the non-pregnant women. All samples were analyzed through PCR with consensus primers GP5+/GP6+. Genotyping was performed using specific primers. To control for confounding factors, the analysis of multivariate logistic regression was applied. The measure of odds ratio (OR) and the 95 % confidence interval (95 % CI) were used. The level of statistical significance was set at 5 % (P ≤ 0.05). HPV DNA was detected in 23/91 (25.3 %) cervical samples from the pregnant women and in 12/92 (13 %) cervical samples from non-pregnant women (P = 0.035). There was a significant association among cervical HPV infection and young age, number of lifetime sexual partners, and the presence of abnormal cervical cytology. HPV16 and HPV18 were the viral types more frequently detected. Out of the 23 HPV-positive pregnant women, 17 (73.9 %) had normal cervical cytology. Our results suggest a higher prevalence of HPV infection in pregnant vs. non-pregnant women. This finding may be related to the relative immunosuppression observed in pregnant women, outlining the importance of the appropriate monitoring of the viral infection in this specific population.

    Bisphenol A is a chemical that is present in a number of products and types of food packaging. Prenatal exposure to bisphenol A may cause behavioural changes in young children. The aim of this study was to investigate exposure to bisphenol A in pregnant Australian women as a surrogate of neonatal exposure. First morning void urine samples were collected from 26 pregnant women at around week 38 of gestation. Bisphenol A was detectable in 85% of the samples analysed. The median concentration in this group of women was 2.41μg/L with a range of bisphenol A concentrations, as did women with a pre-pregnancy BMI of bisphenol A exposure in Australia and reveals that pregnant women have measured biological concentrations of urinary bisphenol A similar to those reported for pregnant women in other developed countries. Given the potential impacts of prenatal bisphenol A exposure, further research in this area is warranted.

    Full Text Available Background: A number of studies on reproduction have mentioned Origanum Vulgare extract’s ability to reduce mortality rates and improve fertility rates. However, other studies have suggested that it is possible to use Origanum Vulgare extract to induce abortion. The aim of this study was to investigate the effect of different doses of Origanum Vulgare on embryo survival and macroscopic abnormalities in mice.Methods: In this study, 24 mice Balb/c female weighting approximately 25-30 g were divided into 4 groups. Origanum Vulgare extract was prepared; different concentrations (2.5, 12.5, and 25 mg in 0.25 ml distilled water were administered, by oral gavage, to three experimental groups of mice between day 6 (starting gastrulation until day 15 of pregnancy (end of organogenesis. The control group consisted of six mice that received 0.25 ml of distilled water daily. On day 16 of study, pregnant mice were anesthetized by chloroform and fetuses were removed and stained with Alcian Blue, Alizarin Red s and microwave irradiation. Morphological and skeletal abnormalities were investigated by light and stereomicroscopes.Results: The results of this study showed that high doses of the Origanum Vulgare extract significantly decreased the mean number of embryos (100.5, P>0.05, mean number of live embryos (70.5, P>0.05 in each mouse and resulted in significant reduction in mean weight(11848 mg, P>0.05 and crown-rump length(11.90.23 mm, P>0.05 and the overall size of fetuses compared to control group, whereas there was no significant difference between the groups receiving low dose of Origanum Vulgare extract with control group. In addition, under the effect of the Origanum Vulgare extract the subcutaneous bleeding seemed (20.1, P>0.05 significantly more frequent compared to the control group. Conclusion: Origanum Vulgare extract did not have any positive effect on fetal development; and high dosages led to an increased incidence rate of

    Healthy, normotensive human pregnancies are associated with striking increases in both plasma volume and vascular sympathetic nerve activity (SNA). In non-pregnant humans, volume regulatory factors including plasma osmolality, vasopressin and the renin-angiotensin-aldosterone system have important modulatory effects on control of sympathetic outflow. We hypothesized that pregnancy would be associated with changes in the relationships between SNA (measured as muscle SNA) and volume regulating factors, including plasma osmolality, plasma renin activity and arginine vasopressin (AVP). We studied 46 healthy, normotensive young women (23 pregnant and 23 non-pregnant). We measured SNA, arterial pressure, plasma osmolality, plasma renin activity, AVP and other volume regulatory factors in resting, semi-recumbent posture. Pregnant women had significantly higher resting SNA (38 ± 12 vs. non-pregnant: 23 ± 6 bursts/minute), lower osmolality and higher plasma renin activity and aldosterone (all P pregnant] vs. 5.17 ± 2.03 [pregnant], P > 0.05). However, regression analysis detected a significant relationship between individual values for SNA and AVP in pregnant (r = 0.71, P pregnant women (r = 0.04). No relationships were found for other variables. These data suggest that the link between AVP release and resting SNA becomes stronger in pregnancy, which may contribute importantly to blood pressure regulation in healthy women during pregnancy.

    Full Text Available Properly selected and prescribed physical activity during pregnancy has a favorable effects on the health of pregnant women and the fetus, and is excellent preparation for childbirth. Absolute and relative contraindications to exercise during pregnancy are well defined, as well as the warning signs to terminate exercise while pregnant. Knowledge of these is essential for physically active pregnant women and exercise professionals that work with pregnant women. Pregnant women should be moderately physically active every day of the week for at least 30 minutes. The term moderate is thoroughly and clearly defined in the guidelines. Resistance exercises during pregnancy are safe but it is advised to use light loads and a large number of repetitions (e.g. 15-20 repetitions. Strength exercises for the pelvic floor muscles deserves a special place during pregnancy. Appropriate forms of physical activity for pregnant women are walking and jogging, swimming and aquatic exercise, cycling, Pilates and yoga, aerobics, fitness and cross-country skiing. Certain forms of physical activity need special adjustments (alpine skiing, ice skating and rollerblading, racket sports, team ball games, horseback riding and scuba diving.

Preeclampsia is characterized by disturbed placentation, suppression of aldosterone and avid renal sodium retention with hypertension. It was hypothesized...... that preeclampsia is associated with low prostasin expression in placenta and spillover of prostasin into urine across the defect glomerular barrier. METHODS: This hypothesis was addressed in a cross-sectional design with 20 healthy pregnant women and 20 women with new onset of preeclampsia (hypertension and 1......+ for protein on urine dipstick). Blood and urine samples were obtained in relation to delivery and placental biopsies were taken immediately after delivery (control = 39 and preeclampsia 40 weeks).

    Full Text Available The objective of this descriptive, cross-sectional, quantitative study was to examine self-care practices developed by pregnant women in a prenatal outpatient clinic. Ninety-nine pregnant women participated. The survey was conducted in a public outpatient clinic in Minas Gerais. A questionnaire was administered. The responses were analyzed using descriptive statistics. The results indicated greater self-care in relation to consumption of toxic substances (alcohol and drugs, hygiene, rest and nutrition. Others, such as physical exercise, wearing sunscreen and breast care were not deemed as priorities by the participants. Most reported receiving self-care guidance from health professionals, especially physicians and nurses. Defining the nature of the theme could contribute to the reorganization of health services, in order to provide better strategies for delivering quality care to pregnant women, especially the development of educational practices. doi: 10.5216/ree.v16i4.21779.

    Cadmium toxicity to the cornea of pregnant rats was studied using the electron microscope and x-ray microanalyzer. In in-vivo experiments, severe corneal edema occurred in pregnant dams that received intraperitoneal injections of cadmium sulphate for 4 days during gestation, but not in nonpregnant rats. Prominent swelling of mitochondria and the occurrence of intra- and intercellular vacuoles in the corneal endothelium were observed only in pregnant dams. In in-vitro experiments, electron-dense deposits consisting of cadmium-oxine complexes were preferentially found in swollen mitochondria of the endothelial cells. Cadmium peaks were obtained from these deposits with x-ray microanalysis. These data suggest that the corneal edema observed after administration of cadmium may imply the disturbance of pump function and barrier function of the corneal endothelium due to the primary toxic effects of this metal on mitochondria.

    Introduction Fragile X syndrome (FXS) is the leading cause of inherited intellectual and developmental disability. Policy development relating to carrier screening programmes for FXS requires input from large studies examining not only test uptake but also psychosocial aspects. This study will compare carrier screening in pregnant and non-pregnant populations, examining informed decision-making, psychosocial issues and health economics. Methods and Analysis Pregnant and non-pregnant women are being recruited from general practices and obstetric services. Women receive study information either in person or through clinic mail outs. Women are provided pretest counselling by a genetic counsellor and make a decision about testing in their own time. Data are being collected from two questionnaires: one completed at the time of making the decision about testing and the second 1 month later. Additional data are gathered through qualitative interviews conducted at several time points with a subset of participating women, including all women with a positive test result, and with staff from recruiting clinics. A minimum sample size of 500 women/group has been calculated to give us 88% power to detect a 10% difference in test uptake and 87% power to detect a 10% difference in informed choice between the pregnant and non-pregnant groups. Questionnaire data will be analysed using descriptive statistics and multivariate logistic regression models. Interview data will be thematically analysed. Willingness-to-pay and cost effectiveness analyses will also be performed. Recruitment started in July 2009 and data collection will be completed by December 2013. Ethics and Dissemination Ethics approval has been granted by the Universities of Melbourne and Western Australia and by recruiting clinics, where required. Results will be reported in peer-reviewed publications, conference presentations and through a website http://www.fragilexscreening.net.au. The results of this study will

    The microcirculation is responsible for distribution of blood within tissues, delivery of oxygen and other nutrients, and regulation of blood pressure. The objective of this study was to compare the sublingual microcirculation of pregnant participants to that of comparable non-pregnant volunteers. Two groups of participants were recruited: a group of pregnant, non-laboring women with singleton pregnancies at term gestation and a control group of age-comparable non-pregnant volunteers. A sidestream dark field imaging device was applied to the sublingual mucosal surface obtaining a steady image for at least 20 s duration, in five visual fields. The resultant five video clips per participant were analyzed blindly and at random to prevent coupling between images. The mean microvascular flow index values for each group were compared using a paired t-test. Thirty-seven participants were recruited (19 pregnant, 18 non-pregnant); a single pregnant participant was withdrawn because of technical issues. Baseline characteristics were similar with the exception of weight and body mass index. The mean microvascular flow index was significantly higher in the pregnant group 2.7 ± 0.2 compared to the non-pregnant group 2.5 ± 0.3 (P = 0.021), while the perfused vessel density and proportion of perfused vessels were not significantly different (P = 0.707 and 0.403, respectively). The microvascular flow index of pregnant women is higher than a comparable non-pregnant group, which appears to correlate with the physiological changes of pregnancy. Copyright © 2013 Elsevier Ltd.

    Full Text Available Purpose: This descriptive study was conducted to determine the factors associated with genital hygiene behaviours in pregnant and non-pregnant women.Method and material: Seventy pregnant women and 70 non-pregnant women, aged between 25 and 45 years, who were in the third trimester of pregnancy and presented to the Gynecology and Obstetrics Clinic at the Faculty of Medicine in Konya Province, Turkey, were included in the study. The data were gathered using a questionnaire with 26 questions designed by the researcher using the Genital Hygiene Behavior Inventory (GHBI.Results: There was no significant difference between the GHBI scores of the pregnant and non-pregnant women (p>0.05. Therefore, both groups were combined, and it was aimed to discover the factors associated with genital hygiene behaviours more effectively. A positive correlation between the GHBI scores and the monthly income was found, whereas there was a negative correlation between the GHBI scores and age, marriage age, number of pregnancies, and birth (p<0.05. There was a significant difference between the GHBI scores and the educational status of the women and their husbands, the employment status of the women and the perceived income status (p<0.05. A statistically significant difference was found between the groups in terms of GHBI scores and the women’s pain and/or bleeding experience during sexual intercourse, vaginal douching, and training on the hygiene of the genital area (p<0.05.Conclusion: There was no significant difference in genital hygiene behaviours between the pregnant and non-pregnant women. This may be attributed to the fact that the genital hygiene practices of women who did not have sufficient knowledge of genital hygiene before they became pregnant did not change during pregnancy. Therefore, we suggest that midwives provide both pregnant and non-pregnant women with training on genital hygiene.

    Objectives This study explored nutrition knowledge of pregnant women, and how it correlated with participant characteristics, their main sources of information and changes to their diet since becoming pregnant. Methods Pregnant women residing in Australia accessing pregnancy forums on the internet were invited to complete a web-based questionnaire on general nutrition and pregnancy-specific nutrition guidelines. Results Of the 165 eligible questionnaire responses, 114 were complete and included in the analysis. Pregnancy nutrition knowledge was associated with education (r s = 0.21, p pregnant women achieved nutrition knowledge scores over 80 %. Few women received nutrition advice during their pregnancy, of which most were advised by their doctor. Dietary changes adopted since becoming pregnant included consuming more fruit, vegetables, dairy and high fibre foods. Conclusions for Practice Pregnant women in this study had limited knowledge of the dietary guidelines for healthy eating during pregnancy. Furthermore, nutrition counselling in maternity care appears to be infrequent. One approach to optimising maternal diets and subsequently preventing adverse health outcomes is to enhance their knowledge of the pregnancy nutrition guidelines through the provision of nutritional counselling. Furthermore, research exploring the access and use of nutrition resources, and nutrition advice provided to pregnant women is recommended to understand how knowledge impacts on dietary behaviour.

    Policies to promote smoking cessation among Medicaid-insured pregnant women have the potential to assist a significant proportion of pregnant smokers. In 2010, Kansas Medicaid began covering smoking cessation counseling for pregnant smokers. Our aim was to evaluate the use of smoking cessation benefits provided to pregnant women as a result of the Kansas Medicaid policy change that provided reimbursement for physician-provided smoking cessation counseling. We examined Kansas Medicaid claims data to estimate rates of delivery of smoking cessation treatment to Medicaid-insured pregnant women in Kansas from fiscal year 2010 through 2013. We analyzed the number of pregnant women who received physician-provided smoking cessation counseling indicated by procedure billing codes (ie, G0436 and G0437) and medication (ie, nicotine replacement therapy, bupropion, or varenicline) located in outpatient managed care encounter and fee-for-service claims data. We estimated the number of Medicaid-insured pregnant smokers using the national smoking prevalence (14%) in this population and the number of live births reported in Kansas. Annually from 2010 to 2013, approximately 27.2%-31.6% of pregnant smokers had claims for nicotine replacement therapy, bupropion, or varenicline. Excluding claims for bupropion, a medication commonly prescribed to treat depression, claims ranged from 9.3% to 11.1%. Following implementation of Medicaid coverage for smoking cessation counseling, less than 1% of estimated smokers had claims for counseling. This low claims rate suggests that simply changing policy is not sufficient to ensure use of newly implemented benefits, and that there probably remain critical gaps in smoking cessation treatment. This study evaluates the use of Medicaid reimbursement for smoking cessation counseling among low-income pregnant women in Kansas. We describe the Medicaid claims rates of physician-provided smoking cessation counseling for pregnant women, an evidence-based and

    After reports of microcephaly and other adverse pregnancy outcomes in infants of mothers infected with Zika virus during pregnancy, CDC issued a travel alert on January 15, 2016, advising pregnant women to consider postponing travel to areas with active transmission of Zika virus. On January 19, CDC released interim guidelines for U.S. health care providers caring for pregnant women with travel to an affected area, and an update was released on February 5. As of February 17, CDC had received reports of nine pregnant travelers with laboratory-confirmed Zika virus disease; 10 additional reports of Zika virus disease among pregnant women are currently under investigation. No Zika virus-related hospitalizations or deaths among pregnant women were reported. Pregnancy outcomes among the nine confirmed cases included two early pregnancy losses, two elective terminations, and three live births (two apparently healthy infants and one infant with severe microcephaly); two pregnancies (approximately 18 weeks' and 34 weeks' gestation) are continuing without known complications. Confirmed cases of Zika virus infection were reported among women who had traveled to one or more of the following nine areas with ongoing local transmission of Zika virus: American Samoa, Brazil, El Salvador, Guatemala, Haiti, Honduras, Mexico, Puerto Rico, and Samoa. This report summarizes findings from the nine women with confirmed Zika virus infection during pregnancy, including case reports for four women with various clinical outcomes. U.S. health care providers caring for pregnant women with possible Zika virus exposure during pregnancy should follow CDC guidelines for patient evaluation and management. Zika virus disease is a nationally notifiable condition. CDC has developed a voluntary registry to collect information about U.S. pregnant women with confirmed Zika virus infection and their infants. Information about the registry is in preparation and will be available on the CDC website.

    We sought to describe the impact of pica, the craving for and intentional ingestion of substances not defined as food, as a risk factor for lead poisoning in New York City (NYC) pregnant women. In order to describe pregnant women with elevated blood lead levels (BLLs) who report pica, NYC health department data from 491 cases of lead-poisoned pregnant women from January 2001 to June 2009 were reviewed. Descriptive frequencies were obtained for women reporting pica. Data were compared between women reporting and not reporting pica. In NYC, of the 43 (9%) lead-poisoned pregnant women reporting pica, 42 (97.7%) were immigrants and 28 (64.6%) had consumed soil. Compared to lead-poisoned pregnant women not reporting pica, women reporting pica had higher peak BLLs (29.5 vs. 23.8 μg/dL, P = 0.0001), were more likely to have had a BLL ≥ 45 μg/dL (OR = 3.3, 95% CI, 1.25, 8.68) and receive chelation (OR = 10.88, 95% CI, 1.49, 79.25), more likely to have emigrated from Mexico (OR = 3.05, 95% CI, 1.38–6.72), and less likely to have completed high school (OR = indeterminate; 0 vs. 34%; P = 0.003). Among NYC lead-poisoned pregnant women, pica was associated with higher peak BLLs. Providers in NYC, and possibly other urban settings, should be vigilant and question pregnant women, especially immigrants, about pica and strongly consider testing this at-risk population for lead poisoning.

    Full Text Available Abstract Background It is known that amino acid oxidation is increased in tumor-bearing rat muscles and that leucine is an important ketogenic amino acid that provides energy to the skeletal muscle. Methods To evaluate the effects of a leucine supplemented diet on the intestinal absorption alterations produced by Walker 256, growing pregnant rats were distributed into six groups. Three pregnant groups received a normal protein diet (18% protein: pregnant (N, tumor-bearing (WN, pair-fed rats (Np. Three other pregnant groups were fed a diet supplemented with 3% leucine (15% protein plus 3% leucine: leucine (L, tumor-bearing (WL and pair-fed with leucine (Lp. Non pregnant rats (C, which received a normal protein diet, were used as a control group. After 20 days, the animals were submitted to intestinal perfusion to measure leucine, methionine and glucose absorption. Results Tumor-bearing pregnant rats showed impairment in food intake, body weight gain and muscle protein content, which were less accentuated in WL than in WN rats. These metabolic changes led to reduction in both fetal and tumor development. Leucine absorption slightly increased in WN group. In spite of having a significant decrease in leucine and methionine absorption compared to L, the WL group has shown a higher absorption rate of methionine than WN group, probably due to the ingestion of the leucine supplemented diet inducing this amino acid uptake. Glucose absorption was reduced in both tumor-bearing groups. Conclusions Leucine supplementation during pregnancy in tumor-bearing rats promoted high leucine absorption, increasing the availability of the amino acid for neoplasic cells and, mainly, for fetus and host utilization. This may have contributed to the better preservation of body weight gain, food intake and muscle protein observed in the supplemented rats in relation to the non-supplemented ones.

    CDC has updated its interim guidance for U.S. health care providers caring for pregnant women with possible Zika virus exposure, to include the emerging data indicating that Zika virus RNA can be detected for prolonged periods in some pregnant women. To increase the proportion of pregnant women with Zika virus infection who receive a definitive diagnosis, CDC recommends expanding real-time reverse transcription-polymerase chain reaction (rRT-PCR) testing. Possible exposures to Zika virus include travel to or residence in an area with active Zika virus transmission, or sex* with a partner who has traveled to or resides in an area with active Zika virus transmission without using condoms or other barrier methods to prevent infection.(†) Testing recommendations for pregnant women with possible Zika virus exposure who report clinical illness consistent with Zika virus disease(§) (symptomatic pregnant women) are the same, regardless of their level of exposure (i.e., women with ongoing risk for possible exposure, including residence in or frequent travel to an area with active Zika virus transmission, as well as women living in areas without Zika virus transmission who travel to an area with active Zika virus transmission, or have unprotected sex with a partner who traveled to or resides in an area with active Zika virus transmission). Symptomatic pregnant women who are evaluated possible Zika virus exposure who do not report clinical illness consistent with Zika virus disease (asymptomatic pregnant women) differ based on the circumstances of possible exposure. For asymptomatic pregnant women who live in areas without active Zika virus transmission and who are evaluated possible exposure, rRT-PCR testing should be performed. If the rRT-PCR result is negative, a Zika virus IgM antibody test should be performed 2-12 weeks after the exposure. Asymptomatic pregnant women who do not live in an area with active Zika virus transmission, who are first evaluated 2-12 weeks

    Pregnancy is a crisis in the human life cycle as an important turning point in aspects of anatomical, physiological and psychosocial changes. An unhappy pregnanus could influence the fetal growth and development and sense of maternal competence as well as bonding with the fetus which profoundly affect the nurture of the infant after delivery. The authors'purposes were to study happiness and related factors in pregnant women having antenatal care at King Chulalongkorn Memorial Hospital. Four hundred and thirty-eight pregnant women from the antenatal clinic at King Chulalongkorn Memorial Hospital were randomly selected to complete a set of questionnaires that consisted of personal information, pregnant information, The Oxford Happiness Questionnaire (OHQ), The Maudsley Personality Inventory (MPI) and The Marital Satisfaction Scale (MSS). Prevalence of happiness level was classified by descriptive analysis. Unpaired t-test, ANOVA and Pearson's Product Moment Correlation analyzed related factors to happiness in pregnant woman. Also Stepwise Multiple Regression Analysis was used to define predictive factors for happiness in pregnant women. The sample had a high level of happiness of 57.3%. Significant related factors to happiness were age between 31-35 years, high education level, high individual and family income, having saving deposition, no drug abuse, improved marital relationship, no conflict with relatives, extrovert and stable personality types and no concerns about post-partum body image. Four predictive factors for happiness in pregnant women were extrovert personality, stable personality, high family income and improved marital relationship. Level of happiness in pregnant women could be predicted by type of personality, family income and marital relationship.

    We have investigated effects of micro- and kappa-opioid agonists and antagonists on plasma oxytocin levels and noradrenaline content in the supraoptic nucleus (SON) and paraventricular nucleus (PVN) of 20-day pregnant rats. beta-Endorphin, oxytocin, estrogen and progesterone profiles in late pregnant and parturient rats were also sought. Stage of estrous cycle was monitored by vaginal smear, and pro-estrous animals were left overnight with male. In the first set of experiments, pregnant rats were monitored and decapitated on days 20 and 21 and after the delivery of second pup. In the second set, 20-day pregnant rats were intracerebroventricularly infused with morphine (50 microg/10 microl), U50,488H (kappa-agonist; 50 microg/10 microl), clocinnamox (micro-antagonist; 50 microg/10 microl) and norbinaltorphimine (kappa-antagonist; 50 microg/10 microl). Controls received saline alone. Serum estrogen and progesterone levels were measured by enzyme immunoassay, and plasma oxytocin and beta-endorphin by radioimmunoassay. Noradrenaline and its metabolite (3,4-dihydroxyphenylglycol) were determined in micropunched hypothalamic nuclei by HPLC-ECD. In parturient rats, oxytocin levels were increased (p oxytocin levels (p oxytocin secretion. We suggest that noradrenaline may mediate the inhibitory effects of micro-opioids on oxytocin release. Our findings have also shown that kappa-opioid receptors are not involved in modulation of oxytocin neurons in late pregnant rats. Copyright 2004 S. Karger AG, Basel

    To compare the prevalences and patterns of intimate partner violence between HIV-positive and HIV-negative pregnant women receiving prenatal care at a tertiary hospital in South East Nigeria A comparative cross-sectional study of HIV-positive and HIV-negative pregnant women was done. Statistical analysis was by descriptive and inferential statistics at 95% level of confidence A total of 220 pregnant women studied. These were equally divided between HIV-positive women (cases) and HIV-negative women (controls). Cases did not differ significantly from controls with respect to age, parity, tribe, religion, marital status, monthly family income. HIV positive respondents experienced physical violence in the course of the index pregnancy six times more than controls; sexual violence about 4 times more than controls and were 12 times more likely to be denied sex by their partner compared to controls. Threat of being hurt, deprivation of financial support and denial of communication were the commonest forms of intimate partner violence among HIV-positive pregnant women and these also occurred significantly more among HIV positive women than the controls. HIV-positive status predisposes pregnant women to increased intimate partner violence more of emotional nature further underlying the enormity of social rejection suffered as a result of HIV infection. Intimate partner violence screening should form part of their routine antenatal care

    Full Text Available Women in substance abuse programs have high rates of smoking. Pregnancy represents a unique opportunity for intervention, but few data exist to guide tailoring of effective interventions. In this study, 44 pregnant and 47 nonpregnant opioid-dependent women enrolled in comprehensive substance abuse treatment received a 6-week smoking cessation intervention based on the 5A's counseling model. The number of daily cigarettes decreased by 49% for pregnant patients and 32% for nonpregnant patients at the 3-month followup. Length of time in substance abuse treatment did not correlate with smoking cessation or reduction for either group. Factors predicting reduction of cigarette smoking differed for pregnant versus nonpregnant patients. For pregnant patients, lower levels of nicotine use prior to intervention and self-reported cigarette cravings predicted successful reduction in smoking. For nonpregnant patients, lower affiliative attachment to cigarettes, reliance on cigarettes for cognitive enhancement, and greater sense of control predicted more successful outcomes.

  17. Digital Receiver Phase Meter

    2008-01-01

    The software of a commercially available digital radio receiver has been modified to make the receiver function as a two-channel low-noise phase meter. This phase meter is a prototype in the continuing development of a phase meter for a system in which radiofrequency (RF) signals in the two channels would be outputs of a spaceborne heterodyne laser interferometer for detecting gravitational waves. The frequencies of the signals could include a common Doppler-shift component of as much as 15 MHz. The phase meter is required to measure the relative phases of the signals in the two channels at a sampling rate of 10 Hz at a root power spectral density digital receiver. The input RF signal is first fed to the input terminal of an analog-to-digital converter (ADC). To prevent aliasing errors in the ADC, the sampling rate must be at least twice the input signal frequency. The sampling rate of the ADC is governed by a sampling clock, which also drives a digital local oscillator (DLO), which is a direct digital frequency synthesizer. The DLO produces samples of sine and cosine signals at a programmed tuning frequency. The sine and cosine samples are mixed with (that is, multiplied by) the samples from the ADC, then low-pass filtered to obtain in-phase (I) and quadrature (Q) signal components. A digital signal processor (DSP) computes the ratio between the Q and I components, computes the phase of the RF signal (relative to that of the DLO signal) as the arctangent of this ratio, and then averages successive such phase values over a time interval specified by the user.

    To investigate the impact of family members and health care providers on the use of folic acid supplements in pregnant women, and to provide basic data for improving the effectiveness of folic acid intervention. A cross-sectional study was conducted in hospitals and households from June to September in 2009. Face-to-face anonymous questionnaires were distributed to 2094 women, who were pregnant at least three months or postpartum in one year, in two counties of Gansu Province. The awareness rate of folic acid was in 62.2% of 2094 pregnant women, and 25.4% of them have taken folic acid. Higher knowledge about folic acid of family members (OR = 0.268, 95% CI 0.208 - 0.346), agreed with taking folic acid by family members (OR = 0.103, 95% CI 0.031 -0.338), and urging pregnant women to take folic acid by family members (OR = 0.147, 95% CI 0.115 - 0.190) were significant predictors for having folic acid taken by pregnant women. Propagating knowledge related to folic acid (OR = 0.252, 95% CI 0.197 - 0.323) and directing pregnant women to use folic acid (OR = 0.168, 95% CI 0.096 - 0.296) by health care providers were also the important predictors for folic acid intake. Family members and health care providers play an important role in affecting the use of folic acid among pregnant women. In order to improve the effectiveness of intervention with folic acid, family members of pregnant women and health care providers should be included into the target population to receive an intensive propaganda campaign on folic acid education to improve the use of folic acid in pregnant women extensively.

    The objective of this study was to provide specific characteristics of injuries and crash characteristics for pregnant occupants from the National Automotive Sampling System/Crashworthiness Data System (NASS/CDS) database for pregnant women as a group, broken down by trimester, and compared to non-pregnant women. Using all NASS/CDS cases collected between the years 2000 and 2012 with at least one pregnant occupant, the entire pregnant data set included 321,820 vehicles, 324,535 occupants, and 640,804 injuries. The pregnant occupant data were compared to the characteristics of NASS/CDS cases for 14,719,533 non-pregnant females 13-44 years old in vehicle crashes from 2000 to 2012. Sixty five percent of pregnant women were located in the front left seat position and roughly the same percentage of pregnant women was wearing a lap and shoulder belt. The average change in velocity was 11.6 mph for pregnant women and over 50% of crashes for pregnant women were frontal collisions. From these collisions, less than seven percent of pregnant women sustained MAIS 2+ injuries. Minor differences between the pregnant and non-pregnant occupants were identified in the body region and source of injuries sustained. However, the data indicated no large differences in injury or crash characteristics based on trimester of pregnancy. Moreover, the risk of an MAIS 2+ level injury for pregnant occupants is similar to the risk of injury for non-pregnant occupants based on the total vehicle change in velocity. Overall this study provides useful data for researchers to focus future efforts in pregnant occupant research. Additionally, this study reinforces that more detailed and complete data on pregnant crashes needs to be collected to understand the risk for pregnant occupants.

    Full Text Available Severe malaria, including cerebral malaria (CM and placental malaria (PM, have been recognized to have many of the features of uncontrolled inflammation. We recently showed that in mice genetic susceptibility to the lethal inflammatory autoimmune disease, systemic lupus erythematosus (SLE, conferred resistance to CM. Protection appeared to be mediated by immune mechanisms that allowed SLE-prone mice, prior to the onset of overt SLE symptoms, to better control their inflammatory response to Plasmodium infection. Here we extend these findings to ask does SLE susceptibility have 1 a cost to reproductive fitness and/or 2 an effect on PM in mice? The rates of conception for WT and SLE susceptible (SLE(s mice were similar as were the number and viability of fetuses in pregnant WT and SLE(s mice indicating that SLE susceptibility does not have a reproductive cost. We found that Plasmodium chabaudi AS (Pc infection disrupted early stages of pregnancy before the placenta was completely formed resulting in massive decidual necrosis 8 days after conception. Pc-infected pregnant SLE(s mice had significantly more fetuses (∼1.8 fold but SLE did not significantly affect fetal viability in infected animals. This was despite the fact that Pc-infected pregnant SLE(s mice had more severe symptoms of malaria as compared to Pc-infected pregnant WT mice. Thus, although SLE susceptibility was not protective in PM in mice it also did not have a negative impact on reproductive fitness.

    Since 2004, the American College of Obstetricians and Gynecologists (ACOG) and the Advisory Committee on Immunization Practices (ACIP) have recommended that pregnant women receive the seasonal influenza vaccine, regardless of pregnancy trimester, because of their increased risk for severe complications from influenza. However, the uptake of the influenza vaccine by pregnant women has been low. During the 2009-2010 influenza season, pregnant women were identified as a priority population to receive the influenza A (H1N1) 2009 (2009 H1N1) monovalent vaccine in addition to the seasonal influenza vaccine. In this issue, we highlight information from the 10 states that collected data using the survey administered by the Pregnancy Risk Assessment and Monitoring System (PRAMS) about seasonal vaccine coverage among women with recent live births and reasons for those who chose not to get vaccinated. The combined estimates from PRAMS of influenza vaccination coverage for the 2009-2010 season, which included data from October 2009 to March 2010, from 10 states were 50.7% for seasonal and 46.6% for 2009 H1N1 vaccine among women with recent live births. Among women who did not get vaccinated, reasons varied from worries about the safety of the vaccines for self and baby to not normally getting the vaccination. Further evaluation is needed on ways to increase influenza vaccination among pregnant women, effectively communicate the risk of influenza illness during pregnancy, and address women's concerns about influenza vaccination safety during pregnancy.

    To assess the adequacy of prenatal care and perinatal outcomes for uninsured pregnant women at two primary care centres in Canada. We conducted a retrospective case comparison study of uninsured women presenting for prenatal care between 2004 and 2007 (n = 71). Control subjects (n = 72) were chosen from provincially insured women presenting for prenatal care during the same period. A modified Kotelchuck Index was used to assess adequacy of care. Frequency of routine prenatal testing (blood tests, ultrasound, cervical swabs, Pap testing, and genetic screening) was compared. Perinatal outcomes assessed included gestational age and birth weight. Uninsured pregnant women presented for initial care 13.6 weeks later than insured women (at 25.6 weeks vs. 12.0 weeks, P care providers (6.6 vs. 10.7, P = 0.05). Using a modified Kotelchuck Adequacy of Prenatal Care Utilization Index, uninsured women were more likely to be categorized as receiving "inadequate care" (uninsured 61.9% vs. insured 11.7%, P care of uninsured pregnant women in Canada. Women in this category presented late for prenatal care, were less likely to have adequate screening tests, and were more likely to receive "inadequate care" as defined by the modified Kotelchuck Index. This information may be valuable in helping to plan programs to improve access to timely and adequate medical care for uninsured pregnant women.

    This work uses cartography as a method for mapping the trajectory of primary healthcare provided to pregnant women. The scope of the study comprises 9 Basic Healthcare Units located in the city of Juazeiro do Norte in the State of Ceará. In all, fifteen women in the 37th to 39th week of pregnancy were selected. Interviews were conducted with these women during the period from January to June 2010. The cartographic findings were depicted in stages in the flowchart, which exposed lacunas in prenatal healthcare, such as the low number of oncotic cytology exams conducted and the lack of educational counseling. Nevertheless, in the interviews, a significant number of pregnant women expressed satisfaction with the prenatal care provided. The good relationships developed between the healthcare professionals and the pregnant women were the main reason that led them to continue the treatment. This fact reinforces the importance of dialogue between these two actors for the success of prenatal healthcare.

    2008-01-01

    Disasters are natural or man-made life-altering events that require preplanning to save lives. Pregnant women are a particularly vulnerable population in such events, because they have special physical and psychosocial needs. Preparations made for labor and birth might have to be drastically altered in the event of an emergency, especially if a woman is separated from her familiar healthcare providers and facilities. The issue of breastfeeding also must be considered in disaster planning for pregnant women, along with occurrences such as food shortages and outbreak of illnesses caused by overcrowding of displaced persons. Recent events such as hurricane Katrina have demonstrated that maternal/child nurses need to become more aware of disaster planning and help to empower pregnant women with knowledge of how to handle their special needs in times of crisis.

    Pregnancy is principally a phenomenon of maternal adaptation to the increasing demands of the growing foetus. Pregnancy causes many visible and invisible changes in human body and it represents one of the best example of selective adaptation in terms of respiratory physiology. To evaluate the changes in dynamic pulmonary function tests in all three trimesters of pregnancy and compare the results between normal pregnant women (case group) and normal non-pregnant women (control group) and also to compare the results of the study with other studies, 50 subjects were selected and divided into two groups, non-pregnant women (n = 20, mean age = 26.5 +/- 2.69 years) and normal pregnant women of all three trimesters (n = 30, mean age = 24.84 +/- 3.00 years). Pulmonary function tests were done by medspiror. Significant decrease in all the parameters of pulmonary function tests like forced vital capacity, forced expiratory volume in one second, peak expiratory flow rate, maximum ventilation volume, were noticed in all trimesters of normal pregnant women as compared to normal non-pregnant women. The data suggest that there is alteration in pulmonary function tests in pregnant women. Continuous Monitoring of pulmonary function tests may prove to be of great value in maternal healthcare as cases of restriction and obstruction in lungs during pregnancy can be identified early and its deterioration can be prevented by proper management.

Average concentration of carnitine in the sera of fifty pregnant women was about 25/83 umol/I: First trimester-30.96 umol/I. Second trimester-29.11 umol/I. Third trimester-25.11 umol/I. concentration of cholesterol and triglyceride in the above-mentioned group was the following: Cholesterol: 258.84 mg/dl triglyceride: 267.02 mg/dl. The above values show that the carnitine level in sera of pregnant women decreases significantly and this decrease is tolerated well by pregnant women. According to our results, the serum carnitine concentration in pregnant women gradually decreases as gestation proceeds. So that the end of this period, is half of its concentration before conception. During pregnancy, there was an inverse correlation between carnitine level and that of cholesterol and triglycerides. Decrease in carnitine concentration and increase in cholesterol and triglyceride levels may be due to the following factors: 1 Increase in FFA oxidation in pregnancy. 2 Hormones. 3 Dilution of the blood. 4 Decrease in Fe storage in pregnant women.

    Pseudomembranous colitis in association with pregnancy has not been well described in English literature. Recent studies show a drastic increase in the incidence and severity of Pseudomembranous colitis in pregnant women, who were once thought to be at low risk. We report here a case of Pseudomembranous colitis in a young healthy immunocompetent pregnant lady. An early suspicion of this entity with the characteristic appearance of pseudomembranes on colonoscopy and histology confirmed the diagnosis enabling prompt treatment and complete recovery without any serious consequences.

    Full Text Available Cystic Fibrosis (CF is a multisystem disease predominantly affecting the airways and predisposing patients to recurrent infections with various multidrug resistant organisms. Mycobacterium tuberculosis (MTB infection is rarely seen, but considered a potential pathogen in CF patients. We report a 26 year old pregnant CF patient on Ivacaftor who was admitted with symptoms suggestive of tuberculosis. Three years prior to the current admission, she had completed four drug anti- MTB therapy for pulmonary tuberculosis and was considered cured as her sputum cultures after six months of treatment were negative. Genotype analysis revealed the current MTB strain to be different from the strain causing the previous infection. After receiving first line anti-tuberculous regimen for nine months, the patient's condition markedly improved culminating in an uneventful pregnancy and delivery. To our knowledge, this is the only reported case of reinfection tuberculosis in a CF patient.

    Zidovudine (AZT) is the main therapeutic agent against HIV vertical transmission and is routinely administered to seropositive pregnant women and their newborns. Toxicity after chronic administration as well as citogenetic effects following developmental AZT exposure has been reported. Furthermore, recent animal data indicate alterations of several behavioral endpoints during the entire lifespan of mice and rats after developmental AZT exposure. In this study, we investigated specific central nervous system (CNS) effects of AZT administration during pregnancy on the offspring. CD-1 mouse females were administered twice daily from day 10 of pregnancy until delivery with either AZT (160 mg/kg) or saline (0.9% NaCl). On PND, 60 male offsprings received an intraperitoneal injection of the D1 receptor agonist 2,3,4,5-tetra-hydro-7,8-diol-1-phenyl-(1H)-3-benzazepine (SKF 38393) (0, 3, and 10 mg/kg), and spontaneous behavior was assessed in an automated activity chamber for 40 min. At variance from what observed in control mice that displayed excessive grooming when administered the higher dose of the D1 agonist, SKF 38393 failed to increase duration of grooming in AZT-treated mice. These data suggest that the D1 receptorial dopaminergic subsystem might be hyporesponsive in mice prenatally exposed to AZT.

    The objective of this study was to evaluate the effect on litter size of 2 analgesics used perioperatively during mouse embryo transfer surgery. Day 2.5 pseudopregnant CD1 mice (n = 96) were divided equally into 2 analgesic treatment groups and a saline control group. Each mouse received a single, subcutaneous dose of buprenorphine hydrochloride (0.1 mg/kg), flunixin meglumine (2.5 mg/kg), or saline immediately after induction of anesthesia with 2.5% isoflurane. Each mouse then was prepared for aseptic surgery. Blastocysts had previously been collected from C57BL/6NCrl female mice that were synchronized and superovulated by using pregnant mare serum gonadotropin and human chorionic gonadotropin and mated with C57BL/6NTac male mice 3.5 d before collection. Viable blastocysts were pooled, and 8 were selected arbitrarily and transplanted into the right uterine horn of each pseudopregnant CD1 mouse. Mice were monitored throughout pregnancy, and the number of pups at birth was documented. No statistically significant difference was found between the 3 groups. These results indicate that perioperative analgesic treatment with buprenorphine or flunixin in the CD1 mouse undergoing embryo transfer is not associated with increased embryonic loss.

    During childhood, residents of areas with stable transmission of Plasmodium falciparum parasites acquire substantial protective immunity to malaria, and adults therefore rarely experience clinical disease episodes. However, susceptibility to infection reappears in pregnant women, particularly...... primigravidae. This is due to appearance of antigenic parasite variants that are restricted to pregnancy. Variant-specific immunity also governs pregnancy-associated recrudescence of Plasmodium berghei infection in pregnant mice. Pregnancy-related changes in the plasma cytokine levels of mice with immunity...

    The negative health consequences of tobacco use are well documented. Some research finds women receiving abortions are at increased risk of subsequent tobacco use. This literature has methodological problems, most importantly, inappropriate comparison groups. This study uses data from the Turnaway Study, a longitudinal study of women who all sought, but did not all receive, abortions at 30 facilities across the United States. Participants included women presenting just before an abortion facility's gestational age limit who received abortions (Near Limit Abortion Group, n = 452), just after the gestational limit who were denied abortions (Turnaways, n = 231), and who received first trimester abortions (First Trimester Abortion Group, n = 273). This study examined the association between receiving versus being denied an abortion and subsequent tobacco use over 2-years. Trajectories of tobacco use over 2 years were compared using multivariate mixed effects regression. Women receiving abortion maintained their level of tobacco use over 2 years. Women denied abortion initially had lower levels of tobacco use than women receiving abortion, but increased their tobacco use from 1 week through 12-18 months post-abortion seeking and then decreased their use by 2 years post-abortion seeking. Baseline parity modified these associations. Receiving an abortion was not associated with an increase in tobacco use over time. Overall, women who carry unwanted pregnancies to term appear to demonstrate similar cessation and resumption patterns to other pregnant women.

  1. Severe Renal Hemorrhage in a Pregnant Woman Complicated with Antiphospholipid Syndrome: A Case Report

    2011-01-01

    Full Text Available Antiphospholipid syndrome is a systemic autoimmune disease with thrombotic tendency. Consensus guidelines for pregnancy with antiphospholipid syndrome recommend low-dose aspirin combined with unfractionated or low-molecular-weight heparin because antiphospholipid syndrome causes habitual abortion. We report a 36-year-old pregnant woman diagnosed with antiphospholipid syndrome receiving anticoagulation treatment. The patient developed left abdominal pain and gross hematuria at week 20 of pregnancy. An initial diagnosis of left ureteral calculus was made. Subsequently abdominal-pelvic computed tomography was required for diagnosis because of the appearance of severe contralateral pain. Computed tomography revealed serious renal hemorrhage, and ureteral stent placement and pain control by patient-controlled analgesia were required. After treatment, continuance of pregnancy was possible and vaginal delivery was performed safely. This is the first case report of serious renal hemorrhage in a pregnant woman with antiphospholipid syndrome receiving anticoagulation treatment and is an instructive case for urological and obstetrical practitioners.

    Full Text Available Objectives: To measure the prevalence and risk factors associated with iron supplementation among pregnant women in the municipality of Rio Grande, Southern Brazil. Methods: All mothers living in this municipality who had children in 2007 were surveyed for demographic, socioeconomic and health care received during pregnancy and childbirth. The statistical analysis consisted of Poisson regression with robust adjustment of variance, and the measure of effect was prevalence ratio (PR. Results: Among the 2,557 mothers interviewed (99% of total, 59% were supplemented with iron during pregnancy period. After adjusting for various confounding factors, a higher PR to iron supplementation was observed among teenagers, women with black skin color, primigravidae, who had six or more antenatal visits, who performed prenatal care in public sector and received vitamin during pregnancy. Conclusion: There is a clear need to increase the iron supplementation coverage of all pregnant women, especially among those currently considered with low gestational risk.

    The aim of the study was to estimate the seroprevalence and risk factors of toxoplasmosis in pregnant women in the department of Annaba, Algeria. We performed a cross-sectional study with analytical purposes. The study was collaboration between the laboratory of Parasitology-Mycology, Faculty of Medicine of Annaba and Parasite Biology Department at the Pasteur Institute of Algeria. A total of 1028 pregnant women who underwent prenatal diagnosis/visit were included over a period of 4 years from January 2006 to December 2009. Immunoglobulin G and M were assayed, using the microparticle enzyme method. The avidity test was used to determine the date of contamination according to age of pregnancy. Search for the parasite was made by inoculation of the placenta and cord blood in white mice. The study compared mother-to-child serological profiles using Western Blot (WB) IgG and IgM. Direct (not well-cooked meat) and indirect (presence of cat, gardening) indicators were recorded to search for parasite exposure. Seroprevalence was 47.8 % (95 % CI: 44.8 to 51.0) and the rate of active toxoplasmosis was 1.1 % (95 % CI 0.6 to 1.8). According to their immune status, this was the first serology for 41 % (CI95 %: 38.0-44.0) of women; 12 % (CI95 %: 10.5-14.6) of primiparous women had only one serology test during their entire pregnancy. Major risk factors were consumption of poorly-cooked meat and exposure to cats. Toxoplasmosis during pregnancy is a serious issue and an effective prevention program is needed.

This figure decreased when compared to the previous year at 26.90 per 1,000 live births. There are several factors influencing the reduction in infant mortality, among others, the availability of various facilities or accessibility factors and health services from skilled medical personnel and the willingness of people to change the traditional life to the norm of modern life in the field of health .this study  aims to explore how families with Mandailing culture care for pregnant mother in in term of nutritional support. Informants in this study are mandailing  Natal community. This study found that If there are health workers or health care in they place, pregnant mother will come to check  their condition and their nutritional status at health workers during childbirth although later they are more happy assisted by traditional birth attendants or village shaman, it can reduce the complications or problems that  the pregnant women who will ultimately reduce maternal mortality and infant mortality rate. Mandailing Natal society is a society that is not closed to new information, the community here is relatively easy in receiving information or a new thing, it's just that sometimes less precise methods of delivery that makes people not obey the things delivered. To improve community health status Mandailing Natal especially pregnant mother and childbirth it is advisable: That the government is aggressively disseminating health programs so that the public is more familiar with the health programs in a way reproduce health workers, especially midwives who will assist communities in improving the health of pregnant mothers especially in term of their nutrition and health services in Mandailing Natal to be more proactive in providing community especially related  information to the

  10. Knowledge of newborn healthcare among pregnant women: basis for promotional and educational programs on breastfeeding

    Directory of Open Access Journals (Sweden)

    Hugo Issler

    2001-01-01

    Full Text Available CONTEXT: Promotional and educational programs relating to breastfeeding are important for reversing the decline in this practice. Most programs are centered exclusively on breastfeeding, although general knowledge about newborn healthcare may be important, especially among pregnant women. OBJECTIVE: To study pregnant women's knowledge about general healthcare of newborns, including breastfeeding aspects. TYPE OF STUDY: Cross-sectional. SETTING: Prof. Samuel Barnsley Pessoa Health School Center, Faculty of Medicine, Universidade de São Paulo, Brazil. PARTICIPANTS: All pregnant women who were registered in the prenatal care program during six consecutive months. MAIN MEASUREMENTS: Aspects of the current gestation, previous gestations and childbirths, knowledge of the general aspects of newborn healthcare and of breastfeeding practices. RESULTS: The results show that only a little over half of the pregnant women had received any information on newborn healthcare. Misinformation was clearly present regarding proper care of the umbilical stump and the nature of jaundice, and worst regarding how to treat oral thrush and jaundice, and about vaccination. In relation to breastfeeding, even though almost all the pregnant women declared their intention to breastfeed, less than half had a concrete response regarding how long to do it for. The low rates obtained in the topics dealing with the duration, nursing intervals and the attitude to be taken towards hypogalactia show unfamiliarity with the breastfeeding technique. The "weak milk" belief, the misinformation about contraceptive methods during breastfeeding and the cost of artificial formulas also have a negative impact on this practice. CONCLUSIONS: Pregnant women's knowledge of newborn healthcare is low, as much in the aspects of general care as in relation to the practice of breastfeeding. These findings must be taken into consideration in educative programs promoting breastfeeding.

    Handler, A; Rosenberg, D; Johnson, T; Raube, K; Kelley, M A

    1997-09-01

    This study describes the use of a Medicaid managed care list to prospectively recruit into a research project pregnant women receiving care from a variety of providers. A list of women enrolled in Medicaid managed care was used to recruit pregnant African-American and Latina women into a study of prenatal care satisfaction. Due to privacy concerns, the researchers were not able to directly access names from the list. Instead, a managed care contract agency sent recruitment letters to 1009 pregnant African-American and Latina Medicaid recipients. Response rates by ethnicity and several other key variables are calculated. The biases associated with this method of recruiting pregnant women from a variety of providers are discussed. Thirty-five percent of the women contacted returned consent forms and agreed to have researchers approach them; the response rate for African-American women was 43% and for Latinas was 29% (p providers. While the use of a prospectively generated list of pregnant Medicaid recipients to recruit low-income pregnant women into a research study may be associated with some selection bias, the potential cost savings, decreased effort, and diminished recall bias may make their use a feasible sampling alternative, particularly when the researcher desires to recruit women seeking care from a variety of provider arrangements.

    For the first time, a population approach was used to describe abacavir (ABC) pharmacokinetics in HIV-infected pregnant and nonpregnant women. A total of 266 samples from 150 women were obtained. No covariate effect (from age, body weight, pregnancy, or gestational age) on ABC pharmacokinetics was found. Thus, it seems unnecessary to adapt the ABC dosing regimen during pregnancy.

  13. Who is telling pregnant women about listeriosis?

    Science.gov (United States)

    Smith, Mary Anne E; MacLaurin, Tanya L

    2011-01-01

    During pregnancy, a woman's immune system is compromised and she is at an increased risk of infection and illness. In particular, the risk of contracting foodborne listeriosis is 20 times greater for pregnant women than for other women of reproductive age. Considering the negative effects of listeriosis on the developing fetus and that more than 380,000 babies were born in Canada in 2010, listeriosis is an important public health concern. And yet, in Canada, it is not clear who is responsible for educating pregnant women on the importance of safe food handling and the avoidance of high-risk foods. Not all women attend prenatal education classes and the circle of care during pregnancy is highly variable. Physicians, however, are very often included in the care circle and may represent a consistent, reliable and trustworthy source of food safety information. At present, only one province has prenatal records that prompt physicians to counsel pregnant women on food safety issues, though all include some assessment of nutrition, diet or supplement use. Improving provincial and territorial prenatal records may be one important way of helping to ensure that critical food safety information is reaching pregnant Canadians.

  14. Scorpion envenomation symptoms in pregnant women

    2007-01-01

    Full Text Available Scorpion envenomation is common in many countries; however, its effects on pregnancy are still unclear. In the present paper, we described the effects of scorpion envenomation on pregnant patients. A retrospective study was carried out considering the clinical and laboratory exams of patients admitted to the emergency room of Habib Bourguiba Hospital, Sfax, Tunisia, from 1990 to 2004. Variability of these clinical and laboratory profiles according to maternal age, gestational age and number of previous parities was also discussed. Among 167 scorpion-envenomed women, age ranged from 17 to 42 years, 7.18% were pregnant. These presented symptoms similar to those of non-pregnant women envenomed by scorpions. Two pregnant patients developed intense pelvic pain and one manifested vaginal bleeding. Although the studied parameters showed non-significant differences, we could conclude that scorpion envenomation may lead to abnormal uterine contraction probably causing preterm delivery. Maternal disturbances induced by scorpion envenomation may influence the fetus development. The effects were more severe in the second trimester of pregnancy.

    Full Text Available In this article the results of a study of psychological readiness of pregnant women to parenthood are presented. Psychological readiness is defined as a structure consisting of three components: the cognitive, emotional, and behavioral, which is consistent with the single theory of psychological processes L. M. Vekkera. It was found that the main component that determines the high level of psychological readiness for motherhood is a cognitive component. The content of the cognitive component includes an understanding of the child as a value. Some results of the research of value orientations of pregnant women in the structure of psychological readiness for parenthood. To identify the value system of pregnant women, the method of “Value Orientations” by M. Rokich was applied. The analysis of empirical data was performed using factor analysis and U criterion of Mann-Whitney. Respondents were distributed into two age groups: first group of 21-25 years (56 persons, second group of 26-30 years (44 persons. All women are nulliparous. The younger age group of pregnant women is characterized by values that are directed at the outside world. Emotional component dominates in the structure of psychological readiness for motherhood. Values of women in the second group are aimed at children. Cognitive and behavioral components dominate in the structure of their psychological readiness for motherhood. Knowledge of the structure of psychological readiness of women to parenthood will help to diagnose disorders of maternal behavior, to design methods of its correction and prevention.

    Despite some studies indicating that thyroid antibody positivity during pregnancy has been associated with adverse pregnancy outcomes, evidence regarding the effects of levothyroxine (LT4) treatment of euthyroid/subclinical hypothyroid pregnant women with autoimmune thyroid disease on pregnancy outcome is limited. We aimed to assess whether pregnant women with autoimmune thyroid disease, but without overt thyroid dysfunction are affected by higher rates of adverse pregnancy outcomes. In addition, we aimed to explore whether LT4 treatment improves the pregnancy outcome of affected women. A prospective study was carried out on pregnant women from the first trimester to delivery. The study was conducted among pregnant women receiving prenatal care in centers under coverage of Shahid Beheshti University of Medical Sciences. Of a total of 1746 pregnant women, screened for thyroid dysfunction, 1028 euthyroid TPOAb-negative (TPOAb(-)) and 131 thyroid peroxidase antibody-positive (TPOAb(+)) women without overt thyroid dysfunction entered the second phase of the study. TPOAb(+) women were randomly divided into two groups: group A (n = 65), treated with LT4 and group B (n = 66), received no treatment. The 1028 TPOAb(-) women (group C) served as a normal population control group. Primary outcomes were preterm delivery and miscarriage and secondary outcomes included placenta abruption, still birth, neonatal admission and neonatal TSH levels. Groups B and C displayed a lower rate of preterm deliveries compared with group A (RR = 0.30, 95% CI: 0.1-0.85, P = 0.0229) and (RR = 0.23, shows the percentages of women with TSH values 95% CI: 0.14-0.40, P women who are positive for TPOAb. © 2017 European Society of Endocrinology.

    Full Text Available Background: Our understanding of pathogenesis of periodontal disease has changed remarkably over a few decades. Rather than being confined to periodontium, periodontal disease may have a wide ranging systemic effects. It is now recognized that it shares most of the common risk factors for diabetes, coronary heart disease preterm low birth weight, miscarriage or early pregnancy loss and preeclampsia. Materials and Methods: The study group comprised of 400 women (200 pregnant women and 200 non-pregnant with an age range of 18-40 years. Maternal demographic and medical data were collected. Periodontal examinations included: Oral hygiene index (OHI-S, gingival index (GI, pocket probing depth and clinical attachment loss (CAL. Results: The results were analyzed using test of proportion when OHI-S was compared in pregnant women with that of non-pregnant individuals, there was no significant difference in good oral hygiene group (P = 0.187, Z = 1.32. When the GI index was evaluated, a definite statistical difference was noted in mild, moderate and severe gingivitis (P - 0.000, Z = 0.365; P - 0.00, Z = 4.17; P - 0.000, Z = 0.75. CAL index revealed a statistical difference was observed healthy periodontium, mild, moderate and severe periodontitis in both pregnant and non-pregnant women (P = −0.000, Z = 3.65; P - 0.000, Z = 5.83; P - 0.001, Z - 3.24; P - 0.000, Z - 6.47. Conclusion: The present study conducted supports the hypothesis that there is a definite correlation between the pregnant women and poor oral hygiene (gingivitis and periodontitis as compared with the non-pregnant controls.

    Full Text Available Sleep problems are common complaints among pregnant women. This study was designed to compare subjective sleep problems in non-pregnancy condition, healthy and preeclamptic pregnancy as a major complication of pregnancy. We hypothesized that some sleep problems are more prevalent in females with preeclampsia.In this cross-sectional study, 102 women with preeclampsia, 106 healthy pregnant women in the third trimester and 103 healthy non-pregnant women were selected through random sampling. Age and parity were matched in the three groups. We used Global sleep assessment questionnaire (GSAQ to check the subjective sleep problems, and then we performed statistical analysis using Analysis of variance (ANOVA and Pearson Chi-square tests.Our findings revealed significant differences in initial insomnia (p = 0.034, fragmented sleep (p = 0.022, snoring (p<0.001, non-idiopathic insomnia (p = 0.045 and sadness and anxiety (p = 0.001 between the three groups. Some sleep problems were more common in preeclampctic compared to healthy pregnant women including initial insomnia, fragmented sleep, snoring, sleep apnea and non-idiopathic insomnia. Moreover, the subjects with preeclampsia revealed more fragmented sleep, snoring, sadness and anxiety and lack of getting enough sleep due to other activities compared to non-pregnant women.Different kinds of sleep problems can occur in subjects with preeclampsia in comparison with the non-pregnant and healthy pregnant subjects. Sleep problems should be evaluated during pregnancy, particularly in pregnant women with preeclampsia, and suitable treatment should be provided for any specific sleep problem.

    Full Text Available Objective(sCarbamazepine (CBZ is an antiepileptic drug that is used widely for the treatment of epileptic seizures. Neural tube defects (NTDs, growth retardation, and nail hypoplasia are the most common features of teratogenic effects of this drug. The purpose of this study was to examine the effect of vitamin B6 on the developmental toxicity of CBZ on mice.Materials and MethodsSixty BALB/c pregnant mice were divided into four experimental and two control groups. Two experimental groups received daily intraperitoneal injection (IP of 30 mg/kg (I or 60 mg/kg (II of CBZ on gestational days (GD 6 to 15. Two other experimental groups received daily IP injection of 30 mg/kg (III or 60 mg/kg (IV of CBZ with 10 mg/kg/day vitamin B6 by gavage 10 days prior to gestation and on GD 6 to 15. Two control groups received normal saline or Tween 20. Dams underwent Cesarean section on GD 18 and embryos were harvested. External/macroscopic observation of fetuses was done by stereomicroscope and external examination for malformations was recorded. Data analyzed by ANOVA and X2 test using SPSS software.ResultsThe mean weight and crown-rump of the fetuses in both CBZ-treated experimental groups were significantly reduced compared with those of the control groups. Various malformations were detected such as brachygnathia, eye malformations, NTDs, vertebral deformity, brachydactyly and growth retardation. Vitamin B6 treatment significantly reduced various CBZ-induced malformations.ConclusionThis study showed that vitamin B6 has a preventive effect on the developmental toxicity of CBZ in mice that can be pursued further for clinical research.

    Intrauterine growth retardation (IUGR) occurs in 3% to 7% of all pregnancies. Recent human studies have indicated that neurodevelopmental disabilities, learning disorders, memory impairment, and mood disturbance are common in IUGR offspring. However, the interactions between IUGR and neurodevelopmental disorders are unclear because of the wide range of causes of IUGR, such as maternal malnutrition, placental insufficiency, pregnancy toxemia, and fetal malformations. Meanwhile, many studies have shown that moderate food restriction enhances spatial learning and improves mood disturbance in adult humans and animals. To date, the effects of maternal moderate food restriction on fetal brain remain largely unknown. In this study, we hypothesized that IUGR would be caused by even moderate food restriction in pregnant females and that the offspring would have neurodevelopmental disabilities. Mid-pregnant mice received moderate food restriction through the early lactation period. The offspring were tested for aspects of physical development, behavior, and neurodevelopment. The results showed that moderate maternal food restriction induced IUGR. Offspring had low birth weight and delayed development of physical and coordinated movement. Moreover, IUGR offspring exhibited mental disabilities such as anxiety and poor cognitive function. In particular, male offspring exhibited significantly impaired cognitive function at 3 weeks of age. These results suggested that a restricted maternal diet could be a risk factor for developmental disability in IUGR offspring and that male offspring might be especially susceptible.

    pityriasis rosea, for intrauterine fetal death. All miscarrying women reportedly revealed an aggressive course of widespread eruption and severe constitutional symptoms; all of them had HHV-6 DNA in the plasma, placenta, skin lesions, and fetal tissues, whereas HHV-7 DNA was detected in the plasma and skin lesions in 3 out of 8 (37.5%) miscarrying women. HHV-6 DNA was found only in the plasma of 2 out of 31 women (6.45%) with normal pregnancy, whereas HHV-7 DNA was detected in the plasma of 3 (9.45%) and in the skin lesions of 2 women (6.45%) with normal pregnancy. The total abortion rate in women who developed pityriasis rosea during their pregnancy (13%) does not differ from that observed in the general population. Nevertheless, it is markedly higher in cases affected during the first 15 gestational weeks (57%) (4,5). Surprisingly, this devastating impact of pityriasis rosea on the outcome of pregnancy is almost completely unknown not only to the public but also to many members of the medical community. It is also largely unknown that, particularly during the first 15 gestational weeks, all pregnant women should avoid any contact with patients known to have pityriasis rosea. Since we have received a considerable number of requests for consultation with pregnant women with pityriasis rosea over the last few years, our group has compiled suggestions approaching the affected patients: 1. If an eruption suggestive for pityriasis rosea occurs in a pregnant woman, the following factors should be excluded: a. Exposure to drugs prior to the development of the rash (biologic agents, captopril, clonidine, hydrochlorothiazide, atenolol, lamotrigine, nortriptyline, barbiturates, metronidazole, terbinafine, omeprazole, non-steroidal anti-inflammatory drugs, and isotretinoin), which are capable of inducing a pityriasis rosea-like eruption (6) and b. Disorders included in the differential diagnosis (syphilis and infections due to parvovirus, herpes virus, cytomegalovirus, and Epstein

    The effect of splenectomy (SPLX) and total-body irradiation (TBI) (50-200 rad) on virgin and pregnant mouse hemopoiesis was studied, using peripheral blood hemogram values and femoral marrow hemopoietic progenitor cell activity (i.e., CFUlt. slash/sub E/, BFU/sub E/, and GM-CFC). The SPLX-maternal red cell counts and hematocrit values were lower than those of SPLX-virgin mice, reflecting the anemia of pregnancy. But the white cell counts of both SPLX-virgin and SPLX-day-14.5 pregnant mice were significantly higher (P<0.005) than normal-virgin mice. Both nonirradiated and day-4 irradiated SPLX-maternal marrow Ep-independent and Ep-dependent CFU/sub E/ were higher than the nonirradiated and day-4 irradiated SPLX-virgin values (respectively, for each TBI dose studied). On the other hand, nonirradiated and day-4 irradiated SPLX-maternal GM-CFC were lower than the nonirradiated and day-4 irradiated SPLX-virgin GM-CFC values. The data demonstrate the potential of the SPLX-maternal femoral marrow to respond to the stress of low-dose TBI with effective compensatory erythropoiesis, possibly at the expense of granulopoiesis.

    Full Text Available Abstract Background Stress during fetal life increases the risk of affective and immune disorders later in life. The altered peripheral immune response caused by prenatal stress may impact on brain function by the modification of local inflammation. In this study we have explored whether prenatal stress results in alterations in the immune response in the hippocampus of female mice during adult life. Methods Pregnant C57BL/6 mice were subjected three times/day during 45 minutes to restraint stress from gestational Day 12 to delivery. Control non-stressed pregnant mice remained undisturbed. At four months of age, non-stressed and prenatally stressed females were ovariectomized. Fifteen days after surgery, mice received an i.p. injection of vehicle or of 5 mg/kg of lipopolysaccharide (LPS. Mice were sacrificed 20 hours later by decapitation and the brains were removed. Levels of interleukin-1β (IL1β, interleukin-6 (IL-6, tumor necrosis factor α (TNF-α, interferon γ-inducible protein 10 (IP10, and toll-like receptor 4 mRNA were assessed in the hippocampus by quantitative real-time polymerase chain reaction. Iba1 immunoreactivity was assessed by immunocytochemistry. Statistical significance was determined by one-way or two-way analysis of variance. Results Prenatal stress, per se, increased IL1β mRNA levels in the hippocampus, increased the total number of Iba1-immunoreactive microglial cells and increased the proportion of microglial cells with large somas and retracted cellular processes. In addition, prenatally stressed and non-stressed animals showed different responses to peripheral inflammation induced by systemic administration of LPS. LPS induced a significant increase in mRNA levels of IL-6, TNF-α and IP10 in the hippocampus of prenatally stressed mice but not of non-stressed animals. In addition, after LPS treatment, prenatally stressed animals showed a higher proportion of Iba1-immunoreactive cells in the hippocampus with

    Full Text Available BACKGROUND: Pregnant women are a target group for receipt of influenza vaccine because there appears to be an elevated mortality and morbidity rate associated with influenza virus infection in pregnant women. The goal of this study is to determine the factors affecting the decisions of pregnant women in Turkey to be vaccinated or not for 2009 H1N1 influenza. METHODOLOGY: We enrolled 314 of 522 (60.2% pregnant women who attended to the antenatal clinics of the Medical Faculty of Kahramanmaras Sutcuimam University's Department of Gynecology and Obstetrics between December 23, 2009, and February 1, 2010. We developed a 48-question survey which was completed in a face-to-face interview at the clinic with each pregnant woman. PRINCIPAL FINDINGS: Of the 314 pregnant women, 27.4% were in the first trimester, 33.8% were in the second trimester, and 38.8% were in the third trimester. Twenty-eight pregnant women (8.9% got vaccinated. Of all the women interviewed, 68.5% stated that they were comfortable with their decisions about the vaccine, 7.3% stated they were not comfortable, and 24.2% stated that they were hesitant about their decisions. The probability of receiving the 2009 H1N1 vaccine was 3.46 times higher among working women than housewives, 1.85 times higher among women who have a child than those who do not, and 1.29 times higher among women with a high-school education or higher than those with only a secondary-school education and below. Correct knowledge about the minimal risks associated with receipt of influenza vaccine were associated with a significant increase in the probability of receiving the 2009 H1N1 vaccine. CONCLUSIONS/SIGNIFICANCE: The number of pregnant women in the study group who received the 2009 H1N1 vaccine was very low (8.9% and two-thirds of them stated that they were comfortable with their decisions concerning the vaccine. Our results may have implications for public health measures to increase the currently low

    Full Text Available Abstract Background When toxoplasmosis is acquired during pregnancy, it can be transmitted to the fetus causing severe lesions in the first two gestational trimesters. This study analyzed the main factors associated with the preventive behavior for toxoplasmosis among pregnant adolescents in the city of Fortaleza in northeast Brazil. Methods It is a cross-sectional study conducted from March 2009 to November 2010, with a sample of 320 pregnant adolescents, ages ranging from 12 to 19 years old, receiving prenatal care in the Public Health Care System. Bivariate and multivariate logistic regression model analyses were used to identify the association between preventive behavior for toxoplasmosis, and the independent variables and 95% confidence interval. Results We observed that 16.3% of the pregnant adolescents showed preventive behavior for toxoplasmosis. The factors positively associated to the preventive behavior for toxoplasmosis were: age group between 12 and 14 years old (OR = 2.75; 95%CI 1.23-6.12 and more than two prenatal consultations (OR = 2.19; 95%CI 1.17-4.09. Conclusions Noteworthy is the importance of a serologic follow-up for pregnant adolescents with clearer and more precise information about risk factors and the importance of adopting preventive behaviors. Thus, it is necessary to establish educational measures for handling food and raising kittens during prenatal care.

    Full Text Available Abstract Background Midwives and obstetricians are the key providers of care during pregnancy and postpartum. Information about the consultations with a general practitioner (GP during this period is generally lacking. The aim of this study is to compare consultation rates, diagnoses and GP management of pregnant women with those of non-pregnant women. Methods Data were retrieved from the Netherlands Information Network of General Practice (LINH, a nationally representative register. This register holds longitudinal data on consultations, prescriptions and the referrals of all patients listed at 84 practices in the Netherlands in 2007–2009, including 15,123 pregnant women and 102,564 non-pregnant women in the same age-range (15 to 45 years. We compared consultation rates (including all contacts with the practice, diagnoses (ICPC-1 coded, medication prescriptions (coded according to the Anatomical Therapeutic Chemical classification system, and rate and type of referrals from the start of the pregnancy until six weeks postpartum (336 days. Results Pregnant women contacted their GP on average 3.6 times, compared to 2.2 times for non-pregnant women. The most frequently recorded diagnoses for pregnant women were ‘pregnancy’ and ‘cystitis/urinary infection’, and ‘cystitis/urinary infection’ and ‘general disease not otherwise specified’ for non-pregnant women. The mean number of prescribed medications was lower in pregnant women (2.1 against 4.4. For pregnant women, the most frequent referral indication concerned obstetric care, for non-pregnant women this concerned physiotherapy. Conclusions GP consultation rates in pregnancy and postpartum shows that GPs are important providers of care for pregnant women. Therefore, the involvement of GPs in collaborative care during pregnancy and postpartum should be reinforced.

However, concerns about mercury contamination of seafood and its potential harm to the developing fetus have created uncertainty about seafood consumption for pregnant women. We compared fish and shellfish consumption patterns, as well as their predictors, among pregnant and non-pregnant women of childbearing age in the US. Methods: Data from 1,260 pregnant and 5,848 non-pregnant women aged 16–49 years from the 1999 to 2006 National Health and Nutrition Examination Survey (NHANES were analyzed. Frequency and type of seafood consumed and adjusted associations of multiple characteristics with seafood consumption were estimated for pregnant and non-pregnant women, separately. Time trends were also examined. Results: There were no significant differences in the prevalence of fish or shellfish consumption, separately or combined, between pregnant and non-pregnant women using either the 30-day questionnaire or the Day 1, 24-h recall. Seafood consumption was associated with higher age, income, and education among pregnant and non-pregnant women, and among fish consumers these groups were more likely to consume ≥3 servings in the past 30 days. Tuna and shrimp were the most frequently reported fish and shellfish, respectively, among both pregnant and non-pregnant women. We observed no significant time trends. Conclusion: There were no differences in seafood consumption between pregnant and non-pregnant women, and the factors related to seafood consumption were similar for both groups. Our data suggest that many women consume less than the recommended two servings of seafood a week.

    Providing needed dental treatment, managing oral infection, and controlling pain are essential functions of dentists for helping patients maintain overall health during pregnancy. Medications commonly required for dental care consist of local anesthetics and associated vasoconstrictors, centrally and peripherally acting analgesics, sedative and anxiolytic agents, and antibiotics. Therapeutic drugs routinely used in dental practice are selected because of their known safety and effectiveness. However, for a pregnant patient requiring dental care, the agents routinely prescribed should be reevaluated for potential risks to the mother and/or fetus. The decision to administer a specific drug requires that the benefits outweigh the potential risks of the drug therapy. This article reviews and updates the recommendations for using dental therapeutic agents, thereby enabling general practitioners to select the safest drugs when treating pregnant dental patients.

    The effect of iron supplementation alone or in combination with ascorbic acid as a preventive and or corrective measure against anemia were tested using pregnant women seeking pre-natal consultation at various health centers in Greater Manila Area. One tablet containing 65 mg iron alone or in combination with ascorbic acid per day during a supplementation period which varied from 16.5 to 17.8 weeks maintained initial hemoglobin and hematocrit levels in non-anemic women. Three tablets of the same iron preparation (total of 195 mg iron) daily resulted in significant increases in hemoglobin and hematocrit in anemic women. Ascorbic acid had no apparent beneficial effect. Considering the positive response to iron treatment, it is recommended that a nationwide program of iron supplementation of pregnant Filipinos be undertaken.

The other 51 women, the second group, had lived more than five years in Lubin-Polkowice and worked in the local non-ferrous metal plants. They were particularly endangered by their exposure to copper, zinc, and lead concentrations. Pregnancy was normal in all cases. Maternal blood, umbilical cord blood, placenta homogenate, and amniotic fluid were examined by techniques of atom-absorption spectrometry. The metals tested were conspicuously absorbed by placental tissue, but no danger to the pregnant women could be established.

    A demographic and obstetric profile of pregnant mothers attending antenatal clinics in kelantan over period of one year was determined by a retrospective study of 10,032 registered pregnant mothers. The prevalence of risk factors related to the age of the mother, parity, weight, haemoglobin level, bad obstetric history and pregnancy related diseases were determined. Prevalence of teenage pregnancy and primigravida accounted for 4.3 and 17.2 percent respectively. Nearly 3.9 percent of the mothers weighed less than 40 kg and 44.5 percent of mothers were found to be anaemic (Hb less than 11g/d) at the first antenatal visit. Only 3.2 percent of the mothers did not have any designated risk factor. Previous bad obstetric history and pregnancy related disease accounted for 17.1 and 3.5 percent of mothers respectively.

    ABSTRACT Background: Women’s empowerment programs during pregnancy focus primarily on increasing women’s health goals and psychological empowerment has been considered important in most issues related to pregnant mothers’ mental health. Using path analysis, this study aims to examine the direct and indirect components of psychological empowerment of pregnant mothers. Methods: This model-testing study was conducted in Gorgan, northwest of Iran during three months in spring of 2015. Through random cluster sampling, a total number of 160 pregnant women were selected from 10 urban medical centers and clinics as primary centers. We used Spritzer’s Psychological empowerment scale. Suitable sampling based on Nunally and Bernstein was followed in the model. The relationships between the dependent variables were then examined by means of path analysis using Amos 18. Results: The psychological empowerment of pregnant mothers (PEPW) model is impacted by individual factors, such as marriage age and employment, including some subjectively rated factors such as marital satisfaction and experience of violence. The PEPW model was deemed appropriate as optimum conditions indicators of goodness of fit; low index of χ2/df shows little difference between the conceptual model and observed data, while RMSEA value indicated the goodness of fit. Other indicators such as CMIN=0.957, CMIN/DF=0.957, P-CLOSE=0.418, χ2=0.957 and probability level=0.328 the fact that the model is ideal. The mothers’ employment had the highest coefficient in the PEPW path model .731 (0.443, 0.965) bootstrap confidence intervals by 95%, and with a p-value of less than 0.05. Conclusions: The mothers’ employment is the most important factor in psychological empowerment, but it cannot be addressed quickly. Programming to increase marital satisfaction followed by a decrease in family violence and prevention of early marriage are necessary for promotion of psychological empowerment during pregnancy.

    Full Text Available Fear of childbirth (FOC is an important psychological problem that is studied worldwide because it affects the well-being of pregnant women. However, in Russia, this problem does not receive adequate attention among researchers. The purpose of the present study was to investigate the conditionality of fear of childbirth (FOC in pregnant women by external and internal factors, which we assumed were the reasons for this fear. As external factors, we considered socio-demographic indicators (e.g., age, marital status, level of education, housing, and the attitude of relatives towards pregnancy as well as indicators of gynecological history (e.g., the term of pregnancy, the outcome of previous pregnancies, and pregnancy complications. As internal (psychological factors of the fear of childbirth, we considered personal anxiety as well as general inclination towards and negative consequences of different fears (20 types of fears and phobias were examined. The study was conducted with a Russian sample of 76 women at different stages of pregnancy and with different socio-demographic indicators and gynecological histories. The analysis of the results showed the absence of significant differences between women who were pregnant with FOC and those without this fear in terms of the external factors considered in this study. According to the study’s data, a general inclination of women to fear is associated with fear of childbirth. However, the findings for the women with FOC did not indicate significant positive correlations between the level of this fear and exposure to any of the 20 types of fear and phobias measured in the study. Furthermore, the results did not detect relationships between the FOC level and women’s personal anxiety. The results allow us to conclude that FOC is a separate phenomenon that is not dependent on other phobias and fears. Fear of childbirth has a subjective and highly individual genesis. It is not a direct consequence of

    Pain of lumbosacral segment of the vertebral column and the pelvis concerns about 45% of all pregnant women. The change of the body posture during pregnancy is the result of gravity centre relocation, which affects the musculosceletal system. Development of the joint, ligament and myofascial dysfunctions, as well as the pain in the lumbosacral segment and the pelvis, are the most common reasons of spine pain. The aim of this review is to present the current state of knowledge about lumbar spine pain in pregnant women with special focus on the pain connected with muscular, joint and ligament disorders. Pregnancy is a serious burden for the female osteo-skeletal system. Lumbar pain with different location and intensification is the negative consequence of the position changes during pregnancy. Pharmacotherapy could be useful only in cases of intensive low back pain, with possible application of small spectrum of drugs that are safe during pregnancy. Physical therapy including manual therapy exercises, massage and techniques of local anesthesia are alternative methods in case of low back pain in pregnant women.

    A pregnant healthcare worker (HCW) may be at risk of occupational exposure to pathogens associated with increased maternal morbidity and mortality as well as perinatal complications. In this article, we review recent literature on infectious diseases commonly encountered in the healthcare setting and of highest concern for a pregnant HCW, focusing on prevention and management of exposures. Pregnancy does not seem to be an independent risk factor for occupationally acquired infectious diseases. Vaccination and standard precautions continue to be the most effective means of preventing transmission to HCWs. Pandemic 2009 influenza A (H1N1) is associated with increased risk of fetal death, highlighting the importance of influenza vaccination. A recent meta-analysis highlights the safety of influenza vaccination during pregnancy. New treatments for hepatitis C have not been studied in pregnancy but pose an important area for research and advancement. Cytomegalovirus immunoglobulin may play a role in postexposure prophylaxis but recent results are inconclusive. Primary prevention with vaccination and use of appropriate infection control precautions is imperative for prevention of occupationally acquired infectious diseases. Pregnant HCWs with occupational exposure to communicable diseases should be evaluated immediately for appropriate postexposure prophylaxis and followed for development of active infection.

    This study on birth control methods used, and HIV infection protection of the HIV infected pregnant women in the obstetrics-gynecology department of Chonburi Hospital from 1 January 1990 to 31 December 1993 revealed that there were 27 HIV infected women with less than 24 weeks gestational age, using birth control methods as such 12 women (44.44%) had tubal resection after abortion, 8 women (29.62%) oral contraceptive pills, 5 women (15.51%) injectable contraception, and 2 women (7.40%) norplants. The 106 HIV infected women with more than 24 weeks gestational age were allowed to deliver. The birth control methods were as follows: 19 women (17.92%) tubal resection, 38 women (35.84%) oral contraceptive pills, 49 women (46.22%) injectable contraception. They were all encouraged to use a condom while having sexual intercourse. Only 40 women of this group are still seen in the follow-up clinic and all are found to be healthy, the birth control is effective and HIV infection is in the early stage. The new born babies were not allowed to be breast fed and were followed-up periodically to 18 months old. Twenty five babies received HIV blood test; 7 babies (28%) were found to be HIV infected. The birth control and HIV infection protection used in this study demonstrate no adverse effects on the disease, and the unexpected problems of these women, as well as the health personnel concerned are reduced both economically and socially. This study provides the guidelines of good care for HIV infected pregnant women.

    Aim: To compare pregnant and non-pregnant females for vitamin D level and periodontal status and to determine if there is any association between the periodontal health and hypovitaminosis D in pregnant women. Materials and Methods: A cross-sectional study was conducted in Jhelum, Pakistan. Participants were pregnant females at ~ 12 weeks of gestation (n = 36) and non-pregnant (n = 35) females selected from the same locality. Periodontal parameters such as probing depth, bleeding on probing, and attachment loss were recorded. Serum samples were taken to measure blood indices and vitamin D levels. Chi-square test and Odds ratio were applied to determine the association between hypovitaminosis D and periodontal status. Results: Vitamin D deficiency was common in the pregnant group compared to non-pregnant (P < 0.001). Blood indices (hemoglobin, hematocrit, mean corpuscular volume) were significantly lower among the pregnant compared to the non-pregnant group (P < 0.001). However, there was no significant difference between the two groups for probing depth and attachment loss. Conclusions: Pregnant women were more deficient in Vitamin D than non-pregnant women. However, no association between low vitamin D levels and periodontal disease was seen in the studied population. PMID:27382540

    Full Text Available The aim of this sstudy was to evaluate the liver glycogen storage in pregnant rats presenting neonatal streptozotocin-induced diabetes and to establish a relation with glycemia and insulin levels. Wistar rats were divided in to two groups: 1 Mild Diabetes (STZ - received streptozotocin (glycemia from 120 to 300 mg/dL, 2 Control - received vehicle (glycemia below 120 mg/dL. At days 0, 7, 14 and 21 of the pregnancy, body weight and glycemia were evaluated. At day 21 of the pregnancy, the rats were anesthetized for blood and liver collection so as to determine insulin and liver glycogen, which showed no changes in the STZ group as compared to the controls. In the STZ group, maternal weight gain were lower as compared to those in the control group. Significantly increased glycemia was observed at days 0 and 14 of the pregnancy in the STZ group. Therefore, neonatally induced diabetes in the rats did not cause metabolic changes that impaired insulin and liver glycogen relation in these rats.

    Aims Adiponectin is an adipokine that has anti-diabetic, anti-atherogenic, anti-inflammatory and angiogenic properties. This hormone has been implicated in both the physiological adaptation to normal pregnancy and obstetrical complications. The aims of this study were to determine normal maternal plasma concentrations of adiponectin throughout gestation and to explore the relationships between plasma adiponectin concentration, pregnancy, and maternal overweight. Study design A cross-sectional study was designed to include normal pregnant women (normal weight and overweight; 11–42 weeks of gestation), and non-pregnant women. Plasma adiponectin concentration was determined by immunoassay. Non-parametric statistics were used for analysis. Results (1) Adiponectin was detectable in the plasma of all patients; (2) there was no significant difference in the median adiponectin concentrations between pregnant and non-pregnant women; (3) plasma adiponectin concentrations were negatively correlated with gestational age only among normal weight pregnant women; and (4) overweight patients had significantly lower adiponectin concentrations than normal weight women. Conclusion Consistent with the increased insulin resistance and weight gain that occur in pregnancy, adiponectin concentrations were negatively correlated with gestational age. The results of this study and the nomogram herein presented can serve as the basis to explore the relationship between adiponectin and pregnancy complications and facilitate the clinical use of this important adipokine. Condensation Plasma adiponectin concentrations decrease with advancing gestational age only in nonobese women. PMID:17919116

    1. The disposition of stiripentol labelled with 14C and 3H on two positions has been studied in the pregnant and non-pregnant female rat after p.o. administration of a 200 mg/kg dose. 2. For both labelled species radioactivity was eliminated mainly in the faeces (69% within 72 h). Urinary excretion was rather low (22% within 72 h). No significant difference was found between the disposition of the two labelled species. 3. For both labelled species concentrations of radioactivity reached a plateau in the plasma and tissues between 1 and 6 h after administration. The liver, fat, mammary gland and adrenal gland were the most extensively-labelled organs. The affinity for the mammary gland was significantly greater in pregnant rats and for the adrenal gland was significantly greater in the non-pregnant rats. The fact that the concentration in the placenta was higher than in the foetus demonstrated that this membrane acts as a barrier for the penetration of the drug in the amniotic fluid. 4. Chromatographic analysis of the faeces and urine showed that an important portion of the dose remained unabsorbed through the gastrointestinal tract. The absorbed fraction undergoes an extensive first-pass metabolism involving mainly the oxidative cleavage of the methylenedioxy ring. Comparison with the results of other work conducted on the non-pregnant rat demonstrated that pregnancy did not affect the disposition and metabolic process.

    Protein turnover was studied in nine non-pregnant (NP) women, eight pregnant (P) and two gestational diabetic (GDM) women. Whole body protein turnover, synthesis and catabolism rates were measured using a single oral dose of /sup 15/N-glycine followed by measurement of enrichment of urinary ammonia. Urinary 3-methylhistidine (3MH) excretion was measured for three consecutive days, including the day of the protein turnover study. Whole body protein turnover and synthesis rates did not differ between the P and NP women, although the synthesis rates tended to be higher in the P group. Gestational diabetic women appeared to have considerably higher rates of both turnover and synthesis. Pregnant women excreted significantly more urinary 3MH than did non-pregnant women. GDM women appeared to have lower 3MH excretion than the P women. Correlation between 3MH excretion and protein turnover rates was nearly significant (p = .06) in the NP women, but was poorly correlated (p = .43) in the P women, suggesting that muscles may be a less important site of whole body protein turnover in pregnancy than in the non-pregnant state.

    The study was conducted to examine effects of a selective copper(I) chelator, neocuproine on the spontaneous or oxytocin-induced contractions in isolated ovariectomized non-pregnant rat, pregnant rat and pregnant human uterus. Uterus activity was evaluated in tissues obtained from bilaterally ovariectomized non-pregnant rats on the 21st day of the operation (n = 24), pregnant rats on the 19-21st day of gestation (n = 24) and women undergoing caesarean section at 38-42 weeks of pregnancy (n = 15). Neocuproine (100 microM) significantly suppressed the amplitude and frequency of the spontaneous contractions in the ovariectomized non-pregnant rat uterus while this agent facilitated the frequency of the spontaneous or oxytocin-induced contractions in the pregnant rat and human uterus without altering the amplitude of these contractions. At high concentration of 200 microM, neocuproine could enhance the amplitude of the contractions in the pregnant uterus. These effects were blocked by a purinergic receptor antagonist, suramin (100 microM) and did not occur following the administration of neocuproine-copper(I) complex or copper(II) chelator cuprizone. alpha, beta-methylene ATP increased the amplitude and frequency of contractions in the pregnant uterus, but not affected the contractions in the ovariectomized non-pregnant rat uterus, and neocuproine potentiated this facilitation effect. However, the suppressive effect of neocuproine on the ovariectomized non-pregnant rat uterus increased in the presence of alpha,beta-methylene ATP. Beta-adrenoceptor blocker, propranolol or nitric oxide synthase inhibitor, L-nitroarginine did not affect the responses to neocuproine. These findings suggest that neocuproine can affect the uterus contractile activity by modulation purinergic excitatory responses and that copper(I)-sensitive mechanisms may play a role in this effect.

    Full Text Available OBJECTIVE: To quantify the collagen fibers in the lacrimal gland of female mice with hyperprolactinemia. METHODS: Forty adult female mice were randomly divided into two groups with 20 animals each: nonpregnant control (CTR1, control group, 0.2 mL of saline solution and nonpregnant experimental (HPRL1, experimental group, 200 µg/day metoclopramide. Treatments lasted for 50 consecutive days. On day 50, 10 females from each group (control and experimental were euthanized in the proestrus phase; then, the blood was collected and the lacrimal glands were removed. Thereafter, the remaining females were placed with the mates and continued to receive treatment with saline solution or metoclopramide. On the 6th post-coital day, 10 pregnant females from the control group (CTR2 and 10 pregnant females from the experimental group (HPRL2 were euthanized, after which blood was collected and the lacrimal glands removed. The lacrimal glands were processed for morphological analyses and collagen quantification, and prolactin and sex steroid levels were measured in the blood samples. Data were statistically analyzed using an unpaired Student t test (p<0.05. RESULTS: Morphological analysis revealed greater structural tissue disorganization of the lacrimal glands in the metoclopramide-treated groups. The total collagen content was significantly higher in the HPRL1 group than in the CTR1 group (p<0.05, whereas the difference between the CTR2 and HPRL2 groups was not significant. CONCLUSION: Our data suggest an impairment in the functioning of the lacrimal gland as a consequence of increased prolactin levels and decreased serum levels of estrogen and progesterone.

    Full Text Available Background: Anemia during pregnancy is a global public health challenge facing the world today. Prevalence of anemia in pregnancy in all the age groups is higher in India as compared to other developing countries. Objective: This study is aimed at determining the magnitude and to explore the socio-demographic and other correlates of anemia among pregnant women. Methodology: This descriptive study with cross-sectional design was conducted in a tertiary care hospital. Pregnant who were attending antenatal clinic for a period of one year were comprised the study material. Correlation between variables was analyzed using the chi-square and odd ratio. Results: Three hundred and thirty eight pregnant women were registered for the present study, whose age ranged from 16 to 45 years with a mean age of 26.08 years. Majority (81.95% participants were found to be anemic. It was observed that anemia was more prevalent in pregnant women age groups i.e. 25-29 years and 30+years i.e. 86.67% and 86.21% respectively. Anemia was 82.92% in women were belonging to Hindu and others religion and 82.24% in women having vegetarian diet. Maximum prevalence (83.93% of anemia was observed in women who were booked for antenatal care in the 3rd trimester of pregnancy. The prevalence of anemia is higher (>85% in women having parity two or more, but this association was not statistically significant. Very few (6.21% were found to be severely anemic as compared to women who were moderately anemic (43.19%. Multiple logistic regression analysis of these factors showed that possibility of anemia is less in women who belong to rural area and it is highly significant. Analysis further showed significant association between anemia and type of diet and other factors like women having parity 1 and 4. Conclusion: The prevalence of anemia amongst the pregnant participants was very high. The socio-demographic and obstetrics factors were found to be associated with anemia. To prevent

    The objective of this study was to investigate the effects of integrated yoga on the quality of life and interpersonal relationships in normal pregnant women. One hundred and two pregnant women between 18 and 20 weeks of gestation who met the inclusion criteria were recruited from the obstetric units in Bangalore and were randomly assigned to two groups of yoga (n = 51) and control (n = 51). Women with medical conditions that could potentially lead to pregnancy complications and those with abnormal fetal parameters were excluded. The yoga group received integrated yoga while control group received standard antenatal exercises, both for 1-h three times a week from 20th to 36th week of gestation. Pre and post assessments were done using WHOQOL-100 and FIRO-B questionnaires. Of the six domains of WHOQOL-100, between groups analysis showed significant improvements in the yoga group compared to the control in the physical (P = 0.001), psychological (P FIRO-B, the yoga group showed significant improvements in 'Expressed Inclusion' (P = 0.02) and 'Wanted Control' (P = 0.009) domains compared to the control group. The integrated yoga is an efficacious means of improving the quality of life of pregnant women and enhancing certain aspects of their interpersonal relationships.

    Full Text Available Hypertensive disorders in pregnancy remain important problem of modern obstetrics, their frequency being 2-8% with no tendency of decreasing. To identify pregnant women with high risk and to conduct preventive treatment is very important for the practitioner. The aim of the study was to develop and justify differential management of pregnants depending on the risk of preeclampsia. 131 pregnant women in I trimester were tested to determine the risk of hypertensive disorders. Prediction model allows to identify pregnant women with risk of hypertensive disorders according to the results of testing thrombophilia genes (presence of 455G → A polymorphism in the gene for fibrinogen β and 4G/5G in gene of plasminogen activator inhibitor - type 1, the level of antibodies to β2 glycoprotein-1, the level of D-dimer and the value of atherogenicity coefficient. Pregnant women with high risk of hypertensive disorders, received prophylactic treatment complex. This complex included antiplatelet therapy, correction of hyperho¬mo¬cysteinemia and hypercholesterolemia levels. Etio-pathogenic concept of prediction and prevention of pre-eclampsia associated with thrombophilia was proposed. The proposed scheme of preventive treatment allowed to normalize blood clotting parameters, lipid metabolism, to reduce the number of thrombophilia markers. The necessity of early and long-term administration of prophylactic complex was proved. This management prevents endothelial damage and deve¬lopment of pathological range of pre-eclampsia. The results of prophylactic treatment were the reduction of preeclampsia cases by 6,5 times (p < 0.05, number of complicated deliveries by 3 times (p <0.05, number of preterm birth by 6,57 times (p <0.05, cases of growth retardation by 9,8 times (p = 0.003, increase of newborns’ weight by 1,24 times (p = 0.02.

    Our aim was to identify social and familial characteristics in the pregnant adolescents. We conducted a cross-sectional survey in 74 pregnant adolescents referred to the Mexican Institute of Social Security's (IMSS) Vicente Guerrero Regional General Hospital High-Risk Module in Acapulco, Guerrero, Mexico from September to November, 2003. An opinion-descriptive questionnaire was formulated by a Committee of Experts and was applied to pregnant adolescents. Variables studied included personal data, obstetrics, and family characteristics. With regard to personal characteristics, average participant age was 17 years, 21 (28%) participants had a high-school academic level, 66 (89%) entertained an interest in continuing their academic studies, 49 (66%) were married, 66 (89%)were homemakers, 35 (47%) mentioned that the reason they got pregnant was to get married, while (36%) got married to leave their original home situation, 54 (73%) accepted the pregnancy, and 71 (96%) of participants reported feelings of responsibility with regard to caring for their infants. Obstetrical characteristics included sexual activity beginning at an average age of 15 years, 63 (85%) of participants' mothers had a pregnancy during adolescence, and 63 (85%) received information on contraceptives but 51 (69%) did not use these. Family characteristics showed 48 cases (65%) had parents who were married, 58 (62%) of participants lived with their spouses' family, 26 (35%) reported more confidence with their mothers, and 68 (92%) had support from their spouse during the pregnancy. It is essential to develop and organize a strategy to improve integral care for pregnant adolescents individually, in the family, and socially that includes active participation in the health education process, needs identification, and deciding on the best choices.

    Vaccination of pregnant women is recommended for some infectious diseases in order to protect both women and offspring through high titres of maternal IgG antibodies. Less is known on the triggering of cellular immune responses by vaccines administered during pregnancy. In an ongoing study on maternal pertussis vaccination (2012-2014) 18 pregnant women were vaccinated with a tetanus-diphtheria-acellular pertussis (Tdap) containing vaccine (Boostrix®) during the third pregnancy trimester. Sixteen age-matched nonpregnant women received the same vaccine in the same time period. A blood sample was taken at the moment of, but before vaccination and one month and one year after vaccination. Anti-Pertussis Toxin (PT), filamentous hemagglutinin (FHA), pertactin (Prn), tetanus toxin (TT) and diphtheria toxin (DT) antibodies were measured by ELISA. Cellular immune responses were analyzed using a diluted whole blood assay, measuring proliferation, and cytokine release in response to vaccine antigens PT, FHA, TT, and to pokeweed mitogen (PWM) as polyclonal stimulus. Antibody levels to all five vaccine components increased significantly and to the same extent after vaccination in pregnant and nonpregnant women. One year after vaccination, antibody titres had decreased particularly to PT, but they were still significantly higher to all antigens than before vaccination. In contrast, proliferative and IFN-γ responses were increased to TT, PT, and FHA in nonpregnant women one month after vaccination, whereas in pregnant women only TT specific T cell responses were increased and to a lesser extent than in the control group. One year after vaccination, cellular responses equaled the baseline levels detected prior to vaccination in both groups. In conclusion, a Tdap vaccination can increase vaccine specific IgG antibodies to the same extent in pregnant and in nonpregnant women, whereas the stimulation of vaccine specific Th1 type cellular immune responses with this acellular vaccine

    Full Text Available The use of sulfadoxine-pyrimethamine (SP as an intermittent preventive treatment (IPT against malaria during pregnancy has become a policy in most sub-Sahara African countries and crucially depends on the efficacy of SP. This study sets out to evaluate the effectiveness of the SP given to the pregnant women in some selected health facilities in the Central Region of Ghana to prevent maternal malaria in pregnant women. A total of 543 pregnant women recruited from 7 selected health centres in Central Region of Ghana participated in the study. Parasite density of Plasmodium falciparum was determined from peripheral blood of the pregnant women using microscopy. High performance liquid chromatography (HPLC and dissolution tester were used to determine the quality of the SP. Malaria infection was recorded in 11.2% of pregnant women who had a history of SP consumption. SP failed the dissolution test. Pregnant women who did not receive IPT-SP were 44%. Low haemoglobin level was recorded in 73.5% of the pregnant women. The results indicated that SP was substandard. IPT-SP is ineffective in preventing malaria infection.

    Objective:To study the Tei index in preeclampsia pregnant women and its correlation with the degree of endothelial injury and hypertension.Methods: A total of 98 preeclampsia pregnant women who were treated in our hospital between May 2014 and July 2016 were divided into mild preeclampsia group (n=62) and severe preeclampsia group (n=36), and 50 normal pregnant women who received antenatal care in our hospital during the same period were selected as normal control group. Ultrasound Tei index as well as the levels of serum endothelial injury indexes and hypertension-related indexes were compared among three groups of pregnant women, and the correlation of Tei index with endothelial injury and hypertension level in preeclampsia pregnant women was further evacuated.Results: Tei index levels in mild preeclampsia group and severe preeclampsia group were higher than that in normal control group, and the Tei index level in severe preeclampsia group was higher than that in mild preeclampsia group. Serum VEGF contents in mild preeclampsia group and severe preeclampsia group were lower than that in the normal control group while sFlt-1, MMP-1 and PAR-1 contents were higher than those in normal control group, 24 h SBP, 24 h DBP, dSBP, dDBP, nSBP and nDBP levels were higher than those in normal control group, and the changes in above indexes in severe preeclampsia group were higher than those in mild preeclampsia group. The Pearson test showed that the Tei index level in preeclampsia pregnant women was directly correlated with endothelial injury and hypertension level.Conclusion: Tei index increases in preeclampsia pregnant women, and its level is directly correlated with endothelial injury and hypertension level.

    Objective: To explore the correlation among the pre-pregnant body mass index (BMI), gestational weight gain (GWG) and umbilical cord blood C peptide, and to investigate the influence of maternal weight management on the incidence of baby long-term metabolic syndrome. Methods: During May to Aug.2015, 485 pregnant women in Zhejiang Taizhou first people's hospital and Taizhou Huangyan maternal &child care service centre were selected in random and divided into four groups according to pre-pregnant BMI: low body mass, normal body mass, over body mass and obese group, and also divided into two groups for getting gestational diabetes mellitus (GDM) or not. According to the gestational weight gain (GWG), all the cases were divided into two groups: above the Institute Of Medicine (IMO) 2009 recommendations or not. According to the outcome, the GDM group which had received weight control treatment, was divided into successful treat group or not. At last, we tested the umbilical cord blood C peptide and birth weight of each newborn and compared the difference in all subgroups. The correlation between the umbilical cord blood C peptide and birth weight were analysed. Results: (1) In the pre-pregnant BMI groups, there were significant differences of incidence of GDM (P0.05). (2) Newborn birth weight and the umbilical cord blood C peptide were positively correlated (r=0.673, PUmbilical cord blood C peptide showed the correlation in all subgroups for different pre-pregnant BMI, GDM or not, overweight or not (Pumbilical cord blood C peptide, the GDM mostly (β=0.58), pre-pregnant BMI secondly (β: 0.36, 0.38) , and GWG weakly (β=0.17). (5) By stratification analysis, in GDM group, low body mass was negatively correlated with umbilical cord blood C peptide (Pumbilical cord blood C peptide (Pumbilical cord blood C peptide. Suitable maternal weight control especially pre-pregnant body mass index control will lower the baby long-term metabolic syndrome incidence.

    Differential preoperative preparation of pregnant women with gestosis, by using calcium antagonists is an effective preventive measure against a circulatory hyperdynamic response to transportation to the operating suite. In pregnant women who had all hemodynamic types at baseline, the eukinetic type achieved during the preparation is retained. The patients with gestosis who did not receive calcium antagonists were found to have a circulatory hyperdynamic response with increased myocardial oxygen uptake (during surgery in particular). The use of calcium antagonists, ketonal, tranexamic acid, and hydroxyethyl starch-130/04 solution in the anesthetic appliance promoted the preservation of eukinetic hemodynamics in all those operated on, without increasing myocardial oxygen demands. The better reaction of the circulatory system and myocardial oxygen demands to surgical injury (the second mediatory wave of the systemic inflammatory response syndrome) correlated with higher neonatal Apgar scores in this category of puerperas with gestosis.

    BACKGROUND: Zinc (Zn) has been shown to greatly influence brain development. Zn supplements may reduce injury to cell membranes of the thyroid gland due to iodine deficiency. OBJECTIVE: To establish an iodine deficiency rat model using low-iodine food, which was supplemented with compound Zn and Zn gluconate, to observe the effects of Zn on brain development, as well as pituitary gland and thyroid gland function in iodine-deficient rats. DESIGN, TIME AND SETTING: Randomized grouping study of neural development was performed in the central laboratory of Shandong Institute for Prevention and Treatment of Endemic Disease from 1998 to 1999. MATERIALS: A total of 270 Wistar, female rats, one month after weaning, were used in this study, including 150 pregnant and 120 neonatal rats. Rats were randomly divided into six groups: normal control, model, iodine, compound Zn, iodine and compound Zn, and zinc gluconate. Each group contained 25 pregnant rats and 20 nenoatal rats. METHODS: The pregnant rats and 20 neonatal rats, and well as the normal group, were fed standard chow and allowed free access to tap water (containing 5 μ g/L iodine and 1 mg/L Zn). The remaining five groups were fed low-iodine chow. However, the model group received distilled water, the iodine group received potassium-iodide distilled water (containing 300 μ g/L iodine), the compound Zn group received distilled water and intragastrically administrated 10 mL/kg compound Zn solution, once per day, the iodine and compound Zn group received distilled water with 300 p g/L iodine and intragastrically administrated 10 mL/kg compound Zn solution, once per day. All treatments lasted 90 days. MAIN OUTCOME MEASURES: All pregnant rats were sacrificed on the day 21 of pregnancy. Body mass, number and rate of fetal absorption, as well as fetal death and malformation, were determined. Thyroid and pituitary gland weights were measured, as well as serum levels of thyroid hormone, gonadotropin, and sex hormones. In the

    Abstract Secondhand smoke (SHS) exposure has negative effects on maternal and infant health. SHS exposure among pregnant women in Argentina and Uruguay has not been previously described, nor has the proportion of those who have received screening and advice to avoid SHS during prenatal care. Women who attended one of 21 clusters of publicly-funded prenatal care clinics were interviewed regarding SHS exposure during pregnancy at their delivery hospitalization during 2011–2012. Analyses were conducted using SURVEYFREQ procedure in SAS version 9.3 to account for prenatal clinic clusters. Of 3,427 pregnant women, 43.4 % had a partner who smoked, 52.3 % lived with household members who smoked cigarettes, and 34.4 % had no or partial smoke-free home rule. Of 528 pregnant women who worked outside of the home, 21.6 % reported past month SHS exposure at work and 38.1 % reported no or partial smoke-free work policy. Overall, 35.9 % of women were exposed to SHS at home or work. In at least one prenatal care visit, 67.2 % of women were screened for SHS exposure, and 56.6 % received advice to avoid SHS. Also, 52.6 % of women always avoided SHS for their unborn baby's health. In summary, a third of pregnant women attending publicly-funded prenatal clinics were exposed to SHS, and only half of pregnant women always avoided SHS for their unborn baby's health. Provider screening and advice rates can be improved in these prenatal care settings, as all pregnant women should be screened and advised of the harms of SHS and how to avoid it. PMID:25427876

    The comparison of the prevalence of malaria in pregnant and non pregnant women living in Dakar has interested 1819 women among whom 950 pregnant and 869 non pregnant. For all the examined women, the global plasmoidic index was 2.6% and the gametocytic index 0.1%. Plasmodium falciparum was the only observed species. According to the obtained results, pregnant women, with a plasmoidic index of 4.5% are more often parasited than the non pregnant women, only affected in a proportion of 0.5% Whatever the age, the number of previous pregnancy, the place of residence, the duration of the stay in Dakar may be, the pregnant women are always more often parasited than the non pregnant women and the registered differences are statistically significant. That situation could come from a greater receptivity of the pregnant women what is admitted by some authors. But a more important proportion of natives from rural area was observed among the pregnant women, from where a difference in the exposure to the risk of impaludation between the two groups that could explain the registered results. The global plasmoidic index of 2.6% obtained in the examined women, reflects well the present situation of the malaria endemy in Dakar, a weak hypo-endemic area.

    Full Text Available OBJECTIVES: To determine the prevalence and correlates of syphilis among pregnant women in rural areas of South China. METHODS: Point-of-care syphilis testing was provided at 71 health facilities in less developed, rural areas of Guangdong Province. Positive samples were confirmed at a local referral center by toluidine red unheated serum tests (TRUST and Treponema pallidum particle agglutination (TPPA tests. RESULTS: Altogether 27,150 pregnant women in rural Guangdong were screened for syphilis. 106 (0.39% syphilis cases were diagnosed, of which 78 (73.6% received treatment for syphilis. Multivariate analysis revealed that older pregnant women (31-35 years old, aOR 2.7, 95% CI 0.99-7.32; older than 35 years old, aOR 5.9, 95% CI 2.13-16.34 and those with a history of adverse pregnant outcomes (aOR 3.64, 95% CI 2.30-5.76 were more likely to be infected with syphilis. CONCLUSIONS: A high prevalence of syphilis exists among pregnant women living in rural areas of South China. Enhanced integration of syphilis screening with other routine women's health services (OB GYN, family planning may be useful for controlling China's syphilis epidemic.

    Full Text Available Background: Human immunodeficiency virus (HIV prevalence is high among rural dwellers and pregnant women. Aims: This study aims to determine the prevalence of HIV and anemia among pregnant women attending antenatal clinic in rural community of Okada, Edo State, Nigeria. Patients and Methods: Anticoagulated blood and sera samples were obtained from 480 women consisting of 292 pregnant and 188 non-pregnant women. Antibodies to HIV were detected in the sera samples and hemoglobin concentration of the anticoagulated blood specimens were determined using standard techniques. Anemia was defined as hemoglobin concentration <11g/dl for pregnant women and <12g/dl for non-pregnant women. Results: Pregnancy was not a risk factor for acquiring HIV infection (pregnant vs. non-pregnant: 10.2% vs. 13.8%; OR=0.713, 95% CI=0.407, 1.259, P = 0.247. The prevalence of HIV was significantly (P = 0.005 and P = 0.025 higher in the age group 10-20 years and 21 - 30 years among pregnant and non-pregnant women respectively. Pregnancy was a risk factor for acquiring anemia (OR=1.717, 95% CI=1.179, 2.500, P = 0.006. Only the age of pregnant women significantly (P = 0.004 affected the prevalence of anemia inversely. Conclusion: The prevalence of HIV and anemia among pregnant women were 10.2% and 49.3% respectively. Pregnancy was associated with anemia. Interventions by appropriate agencies are advocated to reduce associated sequelae.

    The hypotensive effect of adrenomedullin, a potent vasodilator peptide, was examined in conscious pregnant (6, 13 and 20 days of pregnancy) and non-pregnant rats. The intravenous administration of adrenomedullin (0.01-3.0 nmol/kg) produced a dose-dependent depressor response in pregnant and non-pregnant rats. At low doses (0.01-0.1 nmol/kg), the maximum decrease in blood pressure was significantly higher in pregnant rats (20 days pregnant) than in non-pregnant rats. At high doses, no significant difference was observed between the two groups. Furthermore, the administration of adrenomedullin did not significantly affect the basal mean blood pressure (MBP) at any dose when compared to the non-pregnant group at 6 and 13 days of pregnancy. In the ovariectomized rats, the depressor responses in 17beta-estradiol-treated, progesterone-treated and 17beta-estradiol+progesterone-treated rats were not significantly different from that in the control rats, suggesting that the augmented effect on the depressor response to adrenomedullin in pregnant rats may not be due to hormonal changes during pregnancy. The adrenomedullin receptor mRNA level of the descending thoracic aorta was significantly higher in the late-pregnancy rats (20 days of pregnancy). However, the levels did not show any difference between the early-pregnant rats (6 and 13 days of pregnancy) and the non-pregnant rats. These findings suggested that the changes in the depressor response to adrenomedullin which occur at term in pregnant rats may be mediated by changes of adrenomedullin receptor gene expression rather than by sex hormones.

    Full Text Available BACKGROUND: Pregnant women were suspected to be at particular risk when H1N1pnd09 influenza became pandemic in 2009. Our primary objective was to compare the immune responses conferred by MF59®-adjuvanted vaccine (Focetria® in H1N1pnd09-naïve pregnant and non-pregnant women. The secondary aims were to compare influences of dose and adjuvant on the immune response. METHODS: The study was nested in the Copenhagen Prospective Studies on Asthma in Childhood (COPSAC2010 pregnancy cohort in 2009-2010 and conducted as a single-blinded block-randomised [1∶1∶1] controlled clinical trial in pregnant women after gestational week 20: (1 7.5 µg H1N1pnd09 antigen with MF59-adjuvant (Pa7.5 µg; (2 3.75 µg antigen half MF59-adjuvanted (Pa3.75 µg; (3 15 µg antigen unadjuvanted (P15 µg; and in non-pregnant women receiving (4 7.5 µg antigen full adjuvanted (NPa7.5 µg. Blood samples were collected at baseline, 3 weeks, 3 and 10 months after vaccination, adverse events were recorded prospectively. RESULTS: 58 pregnant women were allocated to Pa7.5 µg and 149 non-pregnant women were recruited to NPa7.5 µg. The sero-conversion rate was significantly increased in non-pregnant (NPa7.5 µg compared with pregnant (Pa7.5 µg women (OR = 2.48 [1.03-5.95], p = 0.04 and geometric mean titers trended towards being higher, but this difference was not statistically significant (ratio 1.27 [0.85-1.93], p = 0.23. The significant titer increase rate showed no difference between pregnant (Pa7.5 µg and non-pregnant (NPa7.5 µg groups (OR = 0.49 [0.13-1.85], p = 0.29. CONCLUSION: Our study suggests the immune response to the 7.5 µg MF59-adjuvanted Focetria® H1N1pnd09 vaccine in pregnant women may be diminished compared with non-pregnant women.

    Background Diazinon is an organophosphate that is broadly used as a pesticide to control insects and environmental pollutions. This toxic material is absorbed via inhalation, contact, or digestion and affects different tissues. Objectives This research was a histomorphometric and immunohistochemical study of the fetal liver of mice after exposure to Diazinon. Materials and Methods Twenty-five pregnant BALB/c mice (25 - 30 gr) were divided into five equal groups in the animal lab of Baqiyatallah University of Medical Sciences, Tehran, Iran. The normal group was without any intervention, and two sham groups received an emulsifier as 0.52 and 5.2 μL/volume (5000 cc in desiccator) and two experimental groups received Diazinon 1.3 and 13μL/volume from the seventh to eighteenth days of pregnancy every other day via forty minutes of inhalation. The pregnant mice were killed on the eighteenth day of gestation and their fetuses were removed and evaluated for fetal growth and liver development. Five fixed fetuses were dehydrated through a series of graded ethanol, embedded in paraffin wax and their whole bodies were sectioned sagittally and stained via the hematoxylin-eosin method. Quantitative computer-assisted morphometric studies were done on the fetal liver tissues occupied by hepatocytes, blood islands, liver sinusoids, and apoptosis. Results The mean crown-rump of the fetuses and their mean weight were increased in the experimental group as compared to the sham and normal groups, but the differences were not significant. The mean percentage of the hepatocyte area significantly increased in the experimental group as compared to the sham and control groups (P < 0.0001). However, the mean sinusoid area significantly decreased in the experimental group as compared to the sham and control groups. The mean percentage of the area occupied by apoptotic hepatocytes in the experimental group - 13 μL /volume (8.6143 ± 1.00945) and 1.3 μL /volume (6.1091 ± 0

    Full Text Available During perinatal life, sex steroids, such as estradiol, have marked effects on the development and function of the nervous system. Environmental estrogens or xenoestrogens are man-made chemicals, which animal and human population encounter in the environment and which are able to disrupt the functioning of the endocrine system. Scientific interest in the effects of exposure to xenoestrogens has focused more on fertility and reproductive behaviors, while the effects on cognitive behaviors have received less attention. Therefore, the present study explored whether the organochlorine insecticide Methoxychlor (MXC, with known xenoestrogens properties, administered during the perinatal period (from gestational day 11 to postnatal day 8 to pregnant-lactating females, at an environmentally relevant dose (20µg/kg (body weight/day, would also affect learning and memory functions depending on the hippocampus of male and female offspring mice in adulthood. When tested in adulthood, MXC perinatal exposure led to an increase in anxiety-like behavior and in short-term spatial working memory in both sexes. Emotional learning was also assessed using a contextual fear paradigm and MXC treated male and female mice showed an enhanced freezing behavior compared to controls. These results were correlated with an increased survival of adult generated cells in the adult hippocampus. In conclusion, our results show that perinatal exposure to an environmentally relevant dose of MXC has an organizational effect on hippocampus-dependent memory and emotional behaviors.

    2012-06-01

    Full Text Available Abstract Background Particulate air pollution has been linked to an increased risk of cardiovascular disease and cancer. Animal studies have shown that inhalation of air particulates induces mutations in the male germline. Expanded simple tandem repeat (ESTR loci in mice are sensitive markers of mutagenic effects on male germ cells resulting from environmental exposures; however, female germ cells have received little attention. Oocytes may be vulnerable during stages of active cell division (e.g., during fetal development. Accordingly, an increase in germline ESTR mutations in female mice prenatally exposed to radiation has previously been reported. Here we investigate the effects of nanoparticles on the female germline. Since pulmonary exposure to nanosized titanium dioxide (nanoTiO2 produces a long-lasting inflammatory response in mice, it was chosen for the present study. Findings Pregnant C57BL/6 mice were exposed by whole-body inhalation to the nanoTiO2 UV-Titan L181 (~42.4 mg UV-Titan/m3 or filtered clean air on gestation days (GD 8–18. Female C57BL/6 F1 offspring were raised to maturity and mated with unexposed CBA males. The F2 descendents were collected and ESTR germline mutation rates in this generation were estimated from full pedigrees (mother, father, offspring of F1 female mice (192 UV-Titan-exposed F2 offspring and 164 F2 controls. ESTR mutation rates of 0.029 (maternal allele and 0.047 (paternal allele in UV-Titan-exposed F2 offspring were not statistically different from those of F2 controls: 0.037 (maternal allele and 0.061 (paternal allele. Conclusions We found no evidence for increased ESTR mutation rates in F1 females exposed in utero to UV-Titan nanoparticles from GD8-18 relative to control females.

    During the 2009–2010 A/H1N1 influenza pandemic, pregnant women infected with the virus experienced excess morbidity and mortality when compared with other groups. Once a vaccine was available, pregnant women were a priority group for vaccination. Only a few studies have reported on the uptake of 2009 A/H1N1 influenza vaccine among pregnant women during the pandemic and none were from Asia. The purpose of this study was to examine factors associated with 2009 A/H1N1 influenza vaccine uptake among pregnant women in Hong Kong. Using a multi-center, cross-sectional design, we recruited 549 postpartum women from four post-natal wards in Hong Kong over a 4-month period during the second wave of the A/H1N1 influenza pandemic in the winter and spring of 2010. Only 6.2% (n = 34) of participants had received the 2009 A/H1N1 influenza vaccine and 4.9% (n = 27) had received the seasonal influenza vaccine. The most common reasons for not receiving the 2009 A/H1N1 vaccine were fear of causing harm to themselves or their fetus. A high knowledge level (OR = 19.06; 95% CI 5.55, 65.48), more positive attitudes (OR = 3.52; 95% CI 1.37, 9.07), and having a family member who had the 2009 A/H1N1 influenza vaccine (OR = 7.69; 95% CI 2.92, 20.19) were independently and positively associated with vaccination. Study results show an unacceptably low uptake of the pandemic A/H1N1 influenza vaccine among pregnant women in Hong Kong. Interventions to increase influenza vaccine knowledge and uptake among this group should be a priority for future pandemic planning and seasonal vaccination campaigns.

    Pregnant women and their newborns are at increased risk for influenza-related complications; the latter also have an increased risk for pertussis-related complications. In Germany, seasonal influenza vaccination is recommended for pregnant women since 2010. A dose of pertussis-containing vaccine has been recommended since 2004 for women of childbearing age if they have not been vaccinated within the past 10 years. We conducted a nationwide cross-sectional survey among pregnant women in February/March 2013 to assess knowledge, attitudes, and practices related to influenza vaccination during pregnancy and to identify factors associated with their pertussis vaccination status. In total, 1025 pregnant women participated and provided information through a self-administered questionnaire. Of these, 23.2% were vaccinated against seasonal influenza during the 2012/13 season; 15.9% during their pregnancy. Major reasons for being unvaccinated (n=686 respondents) were lack of confidence in the vaccine (60.4%) and the perception that vaccination was not necessary (40.3%). Influenza vaccination during pregnancy was independently associated with having received influenza vaccine in the previous season, having received a recommendation from a physician, a high level of vaccine-related knowledge and of perceived disease severity. In contrast, knowledge of the recommendation for regular hand-washing to prevent influenza and the perception that vaccine-related side effects were likely to occur or likely to be severe were negatively associated with vaccine uptake. Receipt of a pertussis vaccine in the past 10 years was reported by 22.5% of participants. Pertussis vaccine uptake was independently associated with living in the Eastern federal states and receiving seasonal influenza vaccination annually, while a migration background was associated with a lower uptake. To enhance vaccine uptake in pregnant women and women of childbearing age, special efforts must be undertaken to improve

    Fetal glucocorticoids have an important role in the pre-partum maturation of physiological systems essential for neonatal survival such as glucogenesis. Consequently, in clinical practice, synthetic glucocorticoids, like dexamethasone, are given routinely to pregnant women threatened with pre-term delivery to improve the viability of their infants. However, little is known about the effects of maternal dexamethasone treatment on the glucogenic capacity of either the fetus or mother. This study investigated the effects of dexamethasone treatment using a clinically relevant dose and regime on glycogen deposition and the activities of glucose-6-phosphatase (G6Pase) and phosphoenolpyruvate carboxykinase (PEPCK) in the liver and kidney of pregnant ewes and their fetuses, and of non-pregnant ewes. Dexamethasone administration increased the glycogen content of both the fetal and adult liver within 36 h of beginning treatment. It also increased G6Pase activity in the liver and kidney of the fetuses but not of their mothers or the non-pregnant ewes. Neither hepatic nor renal PEPCK activity was affected by dexamethasone in any group of animals. These changes in glycogen content and G6Pase activity were accompanied by rises in the plasma glucose and insulin concentrations and by a fall in the plasma cortisol level in the fetus and both groups of adult animals. In addition, dexamethasone treatment raised fetal plasma tri-iodothyronine (T(3)) concentrations and reduced maternal levels of plasma T(3) and thyroxine, but had no effect on thyroid hormone concentrations in the non-pregnant ewes. These findings show that maternal dexamethasone treatment increases the glucogenic capacity of both the mother and fetus and has major implications for glucose availability both before and after birth.

    Gestational diabetes mellitus (GDM) is a risk factor for the development of type II diabetes and it causes maternal and child morbidity. Screening for diabetic retinopathy (DR) is important because patients who develop DR have no symptoms until macular edema and/or proliferative diabetic retinopathy (PDR) are already present. The aim of this study was to determine the early retinal findings of GDM. This study was conducted in a tertiary research center. We conducted a prospective cross-sectional study with 3 groups: Group 1 consisted of 36 pregnant women with GDM, Group 2 consisted of 24 healthy pregnant women, and Group 3 consisted of 38 healthy non-pregnant women of reproductive age. Spectralis optical coherence tomography (OCT) was used for the assessment. Macular, choroid, and retinal nerve fiber layer (RNFL) thicknesses were evaluated in patients with GDM and comparisons were made among pregnant women with GDM, healthy pregnant women, and healthy non-pregnant women for these parameters. The nasal part of the RNFL was significantly thinner in the GDM group than in the healthy pregnant group. None of the patients had retinopathy or macular edema at the time of examination. Decreased nasal part of RNFL thickness may be the first retinal change in patients with GDM. Our study suggests that OCT should be performed for the patients with GDM for detection of early retinal changes associated with GDM.

    Full Text Available Abstract Background The function of the hypothalamic-pituitary-adrenal (HPA axis is known to be altered during pregnancy, but it has not been tested with a natural stressor. Methods A group of pregnant women (n = 10 were tested towards the end of pregnancy (mean 36.8 ± 2.5 weeks gestation and about 8 weeks postpartum (mean 7.8 ± 1.5 weeks, together with a matched control group, with a one minute cold hand stressor test. Saliva samples were collected before and 10 and 20 minutes after the test, and stored for later radioimmunoassay of cortisol. Results The control group showed a highly significant response to the test. The pregnant group showed no response, and the postpartum group a variable but non significant one Conclusions This shows that the HPA axis becomes hypofunctional to a natural stressor at the end of pregnancy. It is suggested that one possible evolutionary function for this is to protect the fetus from the stress responses of the mother.

    Acute kidney injury (AKI) is costly and is associated with increased mortality and morbidity. An understanding of the renal physiologic changes that occur during pregnancy is essential for proper evaluation, diagnosis, and management of AKI. As in the general population, AKI can occur from prerenal, intrinsic, and post-renal causes. Major causes of pre-renal azotemia include hyperemesis gravidarum and uterine hemorrhage in the setting of placental abruption. Intrinsic etiologies include infections from acute pyelonephritis and septic abortion, bilateral cortical necrosis, and acute tubular necrosis. Particular attention should be paid to specific conditions that lead to AKI during the second and third trimesters, such as preeclampsia, HELLP syndrome, acute fatty liver of pregnancy, and TTP-HUS. For each of these disorders, delivery of the fetus is the recommended therapeutic option, with additional therapies indicated for each specific disease entity. An understanding of the various etiologies of AKI in the pregnant patient is key to the appropriate clinical management, prevention of adverse maternal outcomes, and safe delivery of the fetus. In pregnant women with pre-existing kidney disease, the degree of renal dysfunction is the major determining factor of pregnancy outcomes, which may further be complicated by a prior history of hypertension.

    Most pregnant smokers report abruptly reducing their cigarettes per day (CPD) by ~50% after learning of pregnancy and making further smaller reductions over the remainder of their pregnancy. Laboratory and naturalistic studies with non-pregnant smokers have found that these types of reductions often lead to changes in smoking topography (i.e., changes in smoking intensity to maintain a desired blood-nicotine level). If pregnant women smoke more intensely, they may expose themselves and their offspring to similar levels of toxicants despite reporting reductions in CPD. Pregnant and non-pregnant female smokers (n = 20 and 89, respectively) participated. At the experimental session, after biochemical confirmation of acute abstinence, participants smoked one usual brand cigarette ad lib through a Borgwaldt CReSS Desktop Smoking Topography device. Carbon monoxide (CO) and measures of nicotine withdrawal, craving, and reinforcement derived from smoking were also collected. The two groups did not differ on demographic or smoking characteristics at screening, except nicotine metabolism rate, which as expected, was faster in pregnant smokers. Analyses suggest that none of the smoking topography parameters differed between pregnant and non-pregnant smokers, although pregnant smokers had a significantly smaller CO boost. Both groups reported similar levels of relief of withdrawal and craving after smoking, but other subjective effects suggest that pregnant smokers find smoking less reinforcing than non-pregnant smokers. Pregnant smokers do not smoke cigarettes differently than non-pregnant women, but appear to find smoking comparatively less pleasurable. This is the first study to assess smoking topography in pregnant women. Pregnant women appear to be at increased risk for smoking cigarettes with more intensity because of (1) their tendency to make significant abrupt reductions in the number of cigarettes they smoke each day after learning of pregnancy and (2) an increase in

    Physiologic changes in the cardiac, respiratory, and renal systems in pregnancy likely impact ventilatory control. Though obstructive sleep apnea and snoring are common in the pregnant population, the predisposition to central respiratory events during sleep and the prevalence of such events is less well studied. The aim of this study was to assess the presence of central apneas during sleep in pregnant women and non-pregnant controls suspected of sleep disordered breathing. Twenty-five pregnant women referred for polysomnography for sleep disordered breathing were compared with non-pregnant controls matched for age, body mass index, gender, and apnea hypopnea index (AHI). Central apnea index was defined as the number of central apneas per hour of sleep, and mixed apnea index was defined as the number of mixed apneas per hour of sleep. Sixty-four percent of pregnant women had a respiratory disturbance index >5 events per hour of sleep. Mean body mass index was 44.1 ± 6.9 kg/m(2) pregnant compared to 44.0 ± 7.3 kg/m(2) in controls. The total number of central apneas observed during sleep in the pregnant group consisted of two central apneas in one patient, and of 98 central apneas in 11 patients in the control group (p = 0.05). Median central apnea index was low in both groups (pregnant 0, interquartile range (IQR) 0, 0 vs. non-pregnant 0, IQR 0, 0.2, p = 0.04). Mixed apnea index was similarly low in both groups. Despite some physiologic changes of pregnancy that impact ventilatory control, the prevalence of central sleep apnea was low in our sample of overweight pregnant women with sleep-disordered breathing.

    This research aimed to develop an initial understanding of the stressors, stress responses, and personal resources that impact African American women during pregnancy, potentially leading to preterm birth. Guided by the ecological model, a prospective, mixed-methods, complementarity design was used with 11 pregnant women and 8 of their significant others. Our integrated analysis of quantitative and qualitative data revealed 2 types of stress responses: high stress responses (7 women) and low stress responses (4 women). Patterns of stress responses were seen in psychological stress and cervical remodeling (attenuation or cervical length). All women in the high stress responses group had high depression and/or low psychological well-being and abnormal cervical remodeling at one or both data collection times. All but 1 woman had at least 3 sources of stress (racial, neighborhood, financial, or network). In contrast, 3 of the 4 women in the low stress responses group had only 2 sources of stress (racial, neighborhood, financial, or network) and 1 had none; these women also reported higher perceived support. The findings demonstrate the importance of periodically assessing stress in African American women during pregnancy, particularly related to their support network as well as the positive supports they receive.

    Intimate partner violence (IPV) during pregnancy is a major public health issue with significant implications for maternal mental health. Less studied is the association between IPV during pregnancy and suicidal ideation. This study reports the prevalence and correlates of suicidal ideation among low-income pregnant women receiving prenatal care at a university obstetrical clinic from February 2009 to March 2010. We performed a cross-sectional analysis of 166 women surveyed between 24 and 28 weeks of gestation using the Edinburgh Postnatal Depression Scale (EPDS) and the Abuse Assessment Screen (AAS). Multiple logistic regression identified factors associated with antenatal suicidal ideation. The prevalence of suicidal ideation was 22.89 %. In the fully adjusted model, antenatal depressive symptomatology (OR = 17.04; 95 % CI 2.10-38.27) and experiencing IPV (OR = 9.37; 95 % CI 3.41-25.75) were significantly associated with an increased risk of antenatal suicidal ideation. The prevalence of antenatal suicidal ideation in the current study was higher than other population-based samples though this sample was predominantly single, low-income, and 19 % experienced IPV during pregnancy. Given the strong association of antenatal suicidal ideation, depressive symptomatology, and IPV, health care providers are urged to identify those women at risk so that antenatal care can be tailored to best support optimal maternal and neonatal outcomes.

    To estimate the number of pregnant and parenting teens currently incarcerated and to assess the correctional health care and social services provided to this target population, we surveyed 430 juvenile detention and long-term correctional facilities in the United States that incarcerate adolescent girls. Of these, 261 (61%) institutions responded and are included in the analysis. Of these facilities, 68% estimated that they were holding 1 to 5 pregnant adolescents on a given day, with a reported yearly (September 1991 to September 1992) census of 2,000 pregnant teenagers and 1,200 teenaged mothers. Nearly half of the facilities (45%) continue to incarcerate after it is determined that a youth is pregnant. Of those institutions that incarcerate pregnant adolescents, 31% provide no prenatal services and 70% provide no parenting classes. Of these facilities, 60% reported at least 1 obstetric complication in their pregnant population. A substantial number of pregnant and parenting adolescents are in custody in the United States. General community standards of health and social services for pregnant and parenting teenagers are not being met by the institutions that incarcerate them.

    2008-06-01

    Full Text Available Abstract Background In rats, oral oleoyl-estrone (OE decreases food intake and body lipid content. The aim of this study was to determine whether OE treatment affects the energy metabolism of pregnant rats and eventually, of their pups; i.e. changes in normal growth patterns and the onset of obesity after weaning. Methods Pregnant Wistar rats were treated with daily intragastric gavages of OE in 0.2 ml sunflower oil from days 11 to 21 of pregnancy (i.e. 10 nmol oleoyl-estrone/g/day. Control animals received only the vehicle. Plasma and hormone metabolites were determined together with variations in cellularity of adipose tissue. Results Treatment decreased food intake and lowered weight gain during late pregnancy, mainly because of reduced adipose tissue accumulation in different sites. OE-treated pregnant rats' metabolic pattern after delivery was similar to that of controls. Neonates from OE-treated rats weighed the same as those from controls. They also maintained the same growth rate up to weaning, but pups from OE-treated rats slowed their growth rate afterwards, despite only limited differences in metabolite concentrations. Conclusion The OE influences on pup growth can be partially buffered by maternal lipid mobilization during the second half of pregnancy. This maternal metabolic "imprinting" may condition the eventual accumulation of adipose tissue after weaning, and its effects can affect the regulation of body weight up to adulthood.

    The management of pregnant women with acute promyelocytic leukemia (APL) is a challenge with limited evidence-based information available. We are reporting a series of 14 consecutive pregnant women with APL who were registered in the PETHEMA Data Centre between 1996 and 2012. APL was diagnosed during early pregnancy in five women, late pregnancy in seven, and two additional patients after delivery in an extremely poor clinical condition (pulmonary and cerebral hemorrhage). Eleven of the 12 patients eligible for induction therapy with all-trans retinoic acid and idarubicin achieved complete remission (CR 92 %) and are still in the first CR. All early pregnancies ended in abortion (four induced and one spontaneous), with four of them achieving CR. Eight of nine women in late pregnancy delivered a healthy infant (six cesarean section and two vaginal delivery). All eight babies developed normally. Our results confirm a high cure rate for pregnant women with APL who received all-trans retinoic acid and idarubicin for induction therapy, and an excellent outcome for babies when the disease is diagnosed during late pregnancy.

    Use of diagnostic imaging studies for evaluation of pregnant patients with medical conditions not related to pregnancy poses a persistent and recurring dilemma. Although a theoretical risk of carcinogenesis exists, there are no known risks for development of congenital malformations or mental retardation in a fetus exposed to ionizing radiation at the levels typically used for diagnostic imaging. An understanding of the effects of ionizing radiation on the fetus at different gestational stages and the estimated exposure dose received by the fetus from various imaging modalities facilitates appropriate choices for diagnostic imaging of pregnant patients with nonobstetric conditions. Other aspects of imaging besides radiation (ie, contrast agents) also carry potential for fetal injury and must be taken into consideration. Imaging algorithms based on a review of the current literature have been developed for specific nonobstetric conditions: pulmonary embolism, acute appendicitis, urolithiasis, biliary disease, and trauma. Imaging modalities that do not use ionizing radiation (ie, ultrasonography and magnetic resonance imaging) are preferred for pregnant patients. If ionizing radiation is used, one must adhere to the principle of using a dose that is as low as reasonably achievable after a discussion of risks versus benefits with the patient.

    To critically determine the relevance of Venereal Diseases Research Laboratories (VDRL) investigation as a routine serological screening for syphilis among pregnant women who receive antenatal care at the University of Nigeria Teaching Hospital (UNTH). A retrospective chart review of result of serological test for syphilis among pregnant women during a five year period (1st January, 1997 to 31st December 2001) was undertaken. A total of 7469 women booked. 7175 had routine serological test. 294 of the booked women failed to submit themselves for screening. The prevalence rate of syphilis in this study was 0.125%. VDRL seroreactivity had in previous studies in this center declined from 3.06% to 1.30%. It further declined to 0.98% in this study. The results strongly show a continuing very low prevalence rate of syphilis in Enugu. Nevertheless, we support continued screening of pregnant women inspite of this low prevalence rate, since this will eradicated the effects of undiagnosed and untreated syphilis.

    Anemia in pregnancy is highly prevalent among antenatal clinic attendees in Enugu, Nigeria despite the practice of routine iron supplementation in pregnancy. The major problem with iron supplementation in pregnancy is compliance, and this may be a potential driver to the persistent high prevalence of anemia in this population. To find out the compliance rate and determinants of compliance to iron supplementation among pregnant women in Enugu, southeastern Nigeria. This was a questionnaire-based cross-sectional study of eligible pregnant women receiving antenatal care at the University of Nigeria Teaching Hospital (UNTH), Ituku/Ozalla, Enugu, Nigeria between April 1, 2012 and January 31, 2013. The knowledge of iron supplementation was 76.3% ( n = 302), however, the compliance rate was 65.9% ( n = 261). Tertiary level of education and high social class were factors significantly associated with compliance to iron supplementation after adjusting for other factors in the binary logistic regression analysis ( P compliance to iron supplementation included gastrointestinal side effects of iron supplements (41.7%), non-affordability of iron supplements (28.3%), and forgetfulness (15.0%) among the antenatal mothers. The compliance rate of 65.9% for iron supplementation by pregnant mothers in Enugu can further be improved by providing the drug free of charge in the short term and improvement in education and socioeconomic class of the populace in the long run.

    In hypertensive pregnant women, the protein-to-creatinine (P/C) ratio is well correlated with 24-h proteinuria and a P/C ratio of 0.27 (g/gCr) is used to reflect significant proteinuria (>0.3 g/day). The aim of this study was to obtain data on normotensive pregnant women, which have so far been lacking. The study population consisted of 74 pregnant women who met the following criteria: (i) ≥22 gestational weeks; (ii) a positive result (≥1+) on dipstick test; (iii) a positive result (>0.27) for P/C ratio; and (iv) 24-h urine test performed within 2 days of the P/C ratio. The correlation between the P/C ratio and 24-h proteinuria, the incidence rates of significant proteinuria according to P/C ratios, and appropriate threshold of the P/C ratio to rule in significant proteinuria were determined using the appropriate statistical methods. The P/C ratio was moderately correlated with the 24-h proteinuria, with a correlation coefficient of 0.64 (95% confidence interval, 0.487-0.76). The area under the receiver-operator curve was 0.76 (95% confidence interval, 0.66-0.87); however, no clear shoulder was identifiable. The incidence rates of significant proteinuria according to P/C ratios of 0.27-0.49, 0.50-0.74, 0.75-0.99, and >1 were 41, 66, 100, and 100%, respectively, indicating that all normotensive pregnant women with a P/C ratio > 0.75 had significant proteinuria. Normotensive pregnant women showed a significant correlation between the P/C ratio and 24-h urine protein level. All normotensive pregnant women with a P/C ratio > 0.75 had significant proteinuria, suggesting that a P/C ratio > 0.75 may be the 'rule-in' threshold of significant proteinuria in this population. © 2016 Japan Society of Obstetrics and Gynecology.

    A female cancer survivor, having suffered malignant lymphoma during childhood and received radio- and chemotherapy, became pregnant. Her uterus was extremely small and in the 22nd week of gestation, acute uterine contractions occurred, leading to preterm delivery and resulting in the death of the infant. Pelvic irradiation in childhood was considered to have caused a small uterus and thus brought on preterm delivery. The younger the patient, the more vulnerable the uterus is to irradiation. The exposure dose to the uterus in pediatric cancer patients should therefore be reduced, especially in younger patients. The cooperation of pediatric cancer specialists and obstetricians is necessary to preserve the future fertility of female cancer survivors.

    This was a substudy of 60 Chlamydia trachomatis-infected women from a larger study of pregnant women in Lima, Peru. Participants were encouraged to bring their partners in for concurrent patient-partner treatment. The alternative partner treatment was expedited partner therapy. Partner treatment uptake was 91.7%. Twenty-one partners (38.2%) received treatment through concurrent patient-partner treatment, and 34 (61.8%) through expedited partner therapy. Living with the partner was significantly associated with having the partner treated (P=0.0028).

  19. HIGH-EFFICIENCY INFRARED RECEIVER

    Full Text Available Recent research and development show promising use of high-performance solid-state receivers of the electromagnetic radiation. These receivers are based on the low-barrier Schottky diodes. The approach to the design of the receivers on the basis of delta-doped low-barrier Schottky diodes with beam leads without bias is especially actively developing because for uncooled receivers of the microwave radiation these diodes have virtually no competition. The purpose of this work is to improve the main parameters and characteristics that determine the practical relevance of the receivers of mid-infrared electromagnetic radiation at the operating room temperature by modifying the electrodes configuration of the diode and optimizing the distance between them. Proposed original design solution of the integrated receiver of mid-infrared radiation on the basis of the low-barrier Schottky diodes with beam leads allows to effectively adjust its main parameters and characteristics. Simulation of the electromagnetic characteristics of the proposed receiver by using the software package HFSS with the basic algorithm of a finite element method which implemented to calculate the behavior of electromagnetic fields on an arbitrary geometry with a predetermined material properties have shown that when the inner parts of the electrodes of the low-barrier Schottky diode is performed in the concentric elliptical convex-concave shape, it can be reduce the reflection losses to -57.75 dB and the standing wave ratio to 1.003 while increasing the directivity up to 23 at a wavelength of 6.09 μm. At this time, the rounded radii of the inner parts of the anode and cathode electrodes are equal 212 nm and 318 nm respectively and the gap setting between them is 106 nm. These parameters will improve the efficiency of the developed infrared optical-promising and electronic equipment for various purposes intended for work in the mid-infrared wavelength range.

    Objective To examine and follow up cervical cytology of pregnant and postpartum women and study their cytopathologic characteristics, so as to determine screening and managing programs for abnormal cervical cytology.Methods Totally 5296 patients in pregnancy and postpartum, in which 3729 by computer-assisted cytology test and 1567 by liquid-based monolayers cytology test, were examined and diagnosed by the Bethesda System made in 2001. Those proven epithelial abnormalities patients were followed up until the lesions regressed to normal. The remaining patients,who exhibited persistent abnormalities or progression, were given further examinations.Results The positive rate of cervical cytological test was 8.72% (462/5296), including squamous carcinoma (SCA) 1case (0.02%), high grade squamous intraepithelial lesion (HSIL) 34 cases (0.64%), low grade squamous intraepithelial lesion (LSIL) 145 cases (2.74%), atypical glandular cells (AGC) 5 cases (0.09%), atypical squamous cells cannot exclude HSIL (ASC-H) 14 cases (0.26%), atypical squamous cells of undetermined significance (ASC-US) 263 cases (4.97%). The 419 proven cytological abnormality cases were followed up successfully. The total transnegative rate in three months was 73.74% (309/419), in which 303 cases (72.32%) persisted normal status for more than six months after regression. And the transnegative rate of ASC-US, ASC-H, AGC, LSIL, and HSIL were 79.56%, 64.29%, 100%,72.14% and 44.12%, respectively. Forty-six cases received biopsy directed by colposcopy. The distribution of coincidence of cytopathologic and histopathologic diagnosis was: SCA 1 case (100%), HSIL 10 cases (76.92%), LSIL 13 cases (65%), ASC-H 2 cases (50%), ASC-US 3 cases (37.50%), total 29 cases (63.04%).Conclusions We should cast more attention to screening cervix lesions in pregnant and postpartum women. Their cytopathologic characteristics are liable to make the clinician give a false positive diagnosis. So we propose to follow up them closely

    Micronutrient deficiencies are prevalent among Zimbabweans with serious health and social implications. Due to a lack of a national micronutrient food fortification policy, the Zimbabwe Ministry of Health and Child Care established a policy for the prevention of maternal micronutrient deficiencies, which centres on pregnant women receiving daily iron and folic acid (IFA) at their first antenatal care visit and throughout pregnancy. Despite these efforts, utilization of IFA supplementation in pregnancy in Zimbabwe is low. This study aimed to understand the experiences and knowledge of IFA supplementation among pregnant women and healthcare workers in Harare, Zimbabwe, and the influence of health-service and social environments on utilization. Semi-structured in-depth interviews were conducted in Shona and English, with pregnant women (n = 24) and healthcare workers (n = 14) providing direct antenatal care services to pregnant women in two high-density community clinics. Data were analysed thematically using NVivo 10. Influences on utilization were at the individual and structural environmental levels. Reasons for low utilization of IFA supplementation included forgetting to take IFA, side effects, misconceptions about IFA, limited access to nutrition information, delayed entry or non-uptake of antenatal care and social norms of pregnant women for IFA supplementation. Utilization was enhanced by knowledge of risks and benefits of supplementation, fear of negative health complications with non-utilization, family support and healthcare worker recommendation for supplementation. Study findings can inform approaches to strengthen micronutrient supplementation utilization to improve the micronutrient status of pregnant women to decrease maternal mortality and improve overall maternal and child health in Zimbabwe. © 2016 John Wiley & Sons Ltd. © 2016 John Wiley & Sons Ltd.

    To examine the relationship of the constructs from the family and school environments and protective individual characteristics to health risk behaviors among pregnant adolescents who smoke. Inner-city adolescents (N = 53), aged 14-19 years, who were participating in a smoking cessation intervention program, completed self-report demographic, social, and behavioral questionnaires. Independent variables included family connectedness, school connectedness, and individual characteristics of religiosity, self-esteem, and grade-point average. Three areas of health risk behavior were dependent variables: delinquent behavior, substance, and precocious sexual behavior. Positive self-esteem served as a protectivefactorfor alcohol use. In contrast to past studies, school connectedness was a risk, not a protective, factor for substance abuse. Neither school nor family connectedness were protective against delinquent or precocious sexual behavior.

    Combined exposure to stressors and chemicals may result in synergistic effects. The effects of prenatal exposure to the organic solvent toluene resemble those observed in offspring of gestationally stressed dams, a possible common mechanism being transfer of stress-/toluene-induced increments...... of corticosteroids from the maternal to the foetal compartment. Pregnant rats were subjected to either 1500 ppm toluene 6 hr/day and/or a schedule of "Chronic mild stress" during the last two weeks of gestation. Exposure to toluene was associated with reduced birth weight and lower maternal weight gain, the latter...... being enhanced by maternal stress. A depressant effect of toluene on maternal corticosterone was observed, hence the study does not provide immediate evidence that transfer of elevated levels of corticosterone from the maternal to the foetal compartment mediates the effects of prenatal exposure...

  4. Obstetricians and the rights of pregnant women.

    Minkoff, Howard; Paltrow, Lynn M

    2007-05-01

    At times, obstetricians are called upon to assist pregnant women in making clinical choices between options that may selectively disadvantage either the mother or the fetus. If a mother chooses a therapeutic course that disadvantages the fetus the physician may feel distressed. In this paper we argue that the choices made by mothers are almost always in the interests of the fetus, and supported by physicians. When there is disagreement it is often due to poor communication. While acknowledging that the rare circumstances in which the physician and patient wish to pursue different clinical paths can be stressful for the provider, we explain why obstetricians should accept the judgment of their patient in all instances. Finally, we will maintain that positing a choice between maternal and fetal interests is, in fact, creating a false choice, in as much as options are presented as being exclusive, when in fact that is not the case.

    A growing body of evidence suggests that physical activity during pregnancy can reduce risk of pregnancy complications. However, factors influencing activity in pregnant Hispanic women, who have high rates of sedentary activity as compared to non-Hispanic whites, are not well characterized. To assess patterns and correlates of physical activity among 1355 participants in Proyecto Buena Salud, a prospective cohort of pregnant Hispanic women in Massachusetts from 2006 to 2011. Analyses were conducted in 2012. Pre-, early-, mid-, and late-pregnancy physical activity were assessed using the Pregnancy Physical Activity Questionnaire. Women reported the frequency and duration of household/caregiving, occupational, sports/exercise, and transportation activities and were classified according to compliance with American College of Obstetricians and Gynecologists guidelines for physical activity. Household/caregiving activity was the primary mode of pregnancy activity ranging from 56% to 60% of total activity while sports/exercise contributed the least (<10%). Compared to nulliparous women, women with two or more children were 85% less likely to become inactive at any time during pregnancy (OR=0.15, 95% CI=0.04, 0.56, p-trend <0.01). Women with one or more children increased their total physical activity on average 9.73±2.04 MET-hours/week and 12.04±2.39 MET-hours/week, respectively, with the onset of pregnancy (p<0.01). Those with the highest levels of total physical activity prior to pregnancy were 87% less likely to become inactive with the onset of pregnancy than those who were inactive prior to pregnancy (OR=0.13, 95% CI= 0.05, 0.29). Findings can inform culturally appropriate interventions designed to reduce pregnancy complications through the promotion of physical activity during pregnancy.

    Full Text Available Objective: The purpose of the study was to assess the knowledge, attitudes, beliefs, and factors associated with the uptake of the influenza (flu vaccination in women within Saudi Arabia during their pregnancy period. Methods: A cross-sectional prospective survey was conducted on 1085 pregnant women at the antenatal clinic over a period of 6 weeks with the provision of influenza vaccination. The questionnaire collected demographic and other data; it included 12 questions on their general knowledge and assessed their attitude toward influenza vaccination, and their awareness of vaccine risk and the potential benefits during pregnancy. The knowledge score obtained was then calculated and compared. Results: A total of 998 patients took part in the questionnaire with a response rate of 92%. There was poor awareness that the flu vaccine is safe to administer during pregnancy (130, 13.1% and that all pregnant women should receive the flu vaccine (190, 19.1%. Pregnant women with flu vaccine knowledge score of ⩽5 (range 0–12 were significantly less likely to take the vaccine (OR 3.78, 95% CI 2.68–5.26, p < 0.001. There was a low uptake of the vaccine (178, 18.1% and only 29 (3.0% had previously been offered the flu vaccine by any doctor during their pregnancy. In addition, 255 (25.8% were against taking the flu vaccine during pregnancy. Conclusion: The knowledge and uptake of the influenza vaccine among Saudi pregnant women are low. One quarter was against the vaccine during pregnancy. Very few believed the flu vaccine to be safe during pregnancy. Rarely, physicians advise their clients to take flu vaccine.

  9. High uptake of HIV testing in pregnant women in Ontario, Canada.

    Directory of Open Access Journals (Sweden)

    Robert S Remis

    Full Text Available In 1999, Ontario implemented a policy to offer HIV counseling and testing to all pregnant women and undertook measures to increase HIV testing. We evaluated the effectiveness of the new policy by examining HIV test uptake, the number of HIV-infected women identified and, in 2002, the HIV rate in women not tested during prenatal care. We analyzed test uptake among women receiving prenatal care from 1999 to 2010. We examined HIV test uptake and HIV rate by year, age and health region. In an anonymous, unlinked study, we determined the HIV rate in pregnant women not tested. Prenatal HIV test uptake in Ontario increased dramatically, from 33% in the first quarter of 1999 to 96% in 2010. Test uptake was highest in younger women but increased in all age groups. All health regions improved and experienced similar test uptake in recent years. The HIV rate among pregnant women tested in 2010 was 0.13/1,000; in Toronto, the rate was 0.28 per 1,000. In the 2002 unlinked study, the HIV rate was 0.62/1,000 among women not tested in pregnancy compared to 0.31/1,000 among tested women. HIV incidence among women who tested more than once was 0.05/1,000 person-years. In response to the new policy in Ontario, prenatal HIV testing uptake improved dramatically among women in all age groups and health regions. A reminder to physicians who had not ordered a prenatal HIV test appeared to be very effective. In 2002, the HIV rate in women who were not tested was twice that of tested women: though 77% of pregnant women had been tested, only 63% of HIV-infected women were tested. HIV testing uptake was estimated at 98% in 2010.

  10. Chlamydia trachomatis infection in a sample of northern Brazilian pregnant women: prevalence and prenatal importance

    Directory of Open Access Journals (Sweden)

    Ana Paula B. de Borborema-Alfaia

    Full Text Available There are limited data regarding prevalence of Chlamydia trachomatis infection among northern Brazilian pregnant women. OBJECTIVE: The purpose of this study was to estimate the prevalence of chlamydial infection among pregnant women in their third trimester and to determine the repercussion of this infection on their offspring. METHODS: In the first phase of this study 100 pregnant women receiving prenatal care in a local public university hospital were examined to assess the prevalence of genital C. trachomatis infection by polymerase chain reaction technique. In the second phase, 88 pregnant women were prospectively evaluated for premature rupture of membranes, puerperal consequences associated with chlamydial infection, and neonates were checked for low-birth weight. RESULTS: The prevalence rate of chlamydial infection was 11%, and 72.7% of the positive participants were predominantly less than 30 years of age (p = 0.1319. A total of 36.4% of the participants had premature rupture of membranes (p = 0.9998. Neither low-birth weight infants nor preterm delivery were observed. A cohort of 16 newborn babies were followedup up to 60 days of life to ascertain outcome: 50% had respiratory symptoms. Neonates born to infected mothers had a higher risk to develop respiratory symptoms in the first 60 days of life. CONCLUSION: The scarcity of data about the effects of chlamydial infection on pregnancy and neonatal outcomes justified this study. Diagnosing and treating chlamydial infection during the third trimester of pregnancy may prevent neonate infection. Therefore, preventive screening should be seen as a priority for early detection of asymptomatic C. trachomatis infection as part of local public health strategies.

    Full Text Available Introduction: Pregnancy, considered as a vulnerable period, exposes women to many new problems. Dealing with new conditions and problems can affect mental health of pregnant women. Hence, the present study aimed to determine the effectiveness of a codified educational behavioral program on the mental health of pregnant women. Methods: In this quasiexperimental study, 61 pregnant women were selected via convinience sampling who were assigned into two experimental (n=31 and control (n=30 groups. The experimental group received 4 weekly sessions of an educational behavioral program in a health center in Ahvaz. The study participants completed General Health Questionnaire (GHQ before the treatment as the pretest and four weeks after the treatment as the posttest. The study data were analyzed via chi square test, paired t- test and independent t-test and significant level of the statistical tests was set less than 0.05. Results: The findings of the present study showed that mean score of mental health in the experimental group was significantly better than that of the control group in the post test (21.1± 3.9 vs. 30.1 ± 6.7. Moreover, the anxiety score (p=0.01, somatoform symptoms (p=0.01 and depression (p=0.02 were significantly better in the experimental group than  the control group in the post test, though the score of social dysfunction (p=0.16 did not demonstrate any improvements in this group. Conclusion: It is can be concluded that educational behavioral program, as a beneficial method of intervention, could be applied in order to improve the pregnant women’ mental health.

    A novel technique and structure that maximizes the extraction of information from reference pulses for UWB-TR receivers is introduced. The scheme efficiently processes an incoming signal to suppress different types of UWB as well as non-UWB interference prior to signal detection. Such a method and system adds a feedback loop mechanism to enhance the signal-to-noise ratio of reference pulses in a conventional TR receiver. Moreover, sampling the second order statistical function such as, for example, the autocorrelation function (ACF) of the received signal and matching it to the ACF samples of the original pulses for each transmitted bit provides a more robust UWB communications method and system in the presence of channel distortions.

    A description of the general design of both the block 3 and block 4 receiver-exciter controllers for the Deep Space Network (DSN) Mark IV-A System is presented along with the design approach. The controllers are designed to enable the receiver-exciter subsystem (RCV) to be configured, calibrated, initialized and operated from a central location via high level instructions. The RECs are designed to be operated under the control of the DMC subsystem. The instructions are in the form of standard subsystem blocks (SSBs) received via the local area network (LAN). The centralized control provided by RECs and other DSCC controllers in Mark IV-A is intended to reduce DSN operations costs from the Mark III era.

    Some pregnant women discontinue iron supplements consumption due to Gastrointestinal (GI) complications, whereas pregnancy induces the same complications physiologically. The aim of the present study was to assess GI complications of ferrous sulfate in pregnant women. This randomized, double-blind, placebo-controlled clinical trial was performed on 176 pregnant women referred to prenatal care clinic of Maryam Hospital from April 2011 to February 2012. Pregnant women with Hb ≥ 13.2 gr/dL at 13(th) - 18(th) weeks of gestation were selected based on the inclusion criteria and were randomly assigned to the ferrous sulfate and placebo groups. The ferrous sulfate group (n = 90) received a 50-mg ferrous sulfate tablet daily from the 20(th) week to the end of pregnancy and the placebo group (n = 89) received one placebo tablet in the same way. All participants were visited twice at 24(th) - 28(th) and 32(nd) - 36(th) weeks to assess the GI complications as well as Hb level to determine the Hb changes in two groups. Chi-square test, t-test and Kolmogorov-Smirnov test were used to analyze the data. P value of ferrous sulfate and placebo groups at 24(th) - 28(th) and 32(nd) - 36(th) weeks. Hemoglobin drop lower than 10.5 gr/dL at 24(th) - 28(th) weeks or lower than 11 g/dL at 32(nd) - 36(th) weeks was not observed in any cases. It can be concluded that GI complications in pregnant women using ferrous sulfate are mostly caused by physiologic changes of pregnancy rather than ferrous sulfate; therefore, it is not reasonable to stop using ferrous sulfate due to GI complications.

    Whole body autoradiograms of male, spayed and pregnant female mice after injection of (/sup 3/H) zearalenone showed a rapid excretion of radioactivity into the bile as well as the urine. Specific localization was found in oestrogen target organs as the uterus, interstitial cells of the testicle and the follicles of the ovary. Unlike natural oestrogens zearalenone and/or its metabolites were not found in the adrenal cortex and bronchi of the lungs. Detection of radioactivity in an increased amount of fluid in the pleural and peritoneal cavities suggests an additional site of action of zearalenone. In the pregnant mice used, radioactivity was found only in the foetuses of late pregnancy mainly in the kidney, bile and connective tissue.

Nine mixed breed bitches with mean age of 3 year-old were submitted to the same anesthetic procedure in two different moments: the first one envolving non-pregnant bitches and the second one 45 day pregnant bitches. All bitches received acepromazine (0,05mg kg-1 intravenously as premedication, propofol (5mg kg-1 by the same way and sevoflurane diluted in oxygen. The variables measured were: heart rate and respiratory rate, systolic, mean and diastolic blood pressure, rectal temperature, end-tidal carbon dioxide pressure, oxyhemoglobin saturation, pH, oxygen tension, carbon dioxide tension, bicarbonate and base excess. The parameters were evaluated before (M0 and 15 minutes after tranquilization (M1, 15 minutes after parameters stabilization of inhalation anesthesia (M2 and every 15 minutes during 60 minutes (M3, M4, M5, M6, except pH and blood gas values which were measured before tranquilization (M0, 15 minutes after parameters stabilization (M2 and at 60 minutes of anesthesia (M6. The heart rate increased in the pregnant bitch before and 15 minutes after tranquilization and there was blood pressure and rectal temperature decrease. The statistical evaluation used were Analysis of Variance and Tukey‘s test (P<0,05. These results allowed the conclusion that the anesthetic protocol didn’t change the variables measured, which can be employed safely in case of surgical and/or anesthetic procedure in 45 day pregnant bitches.

    Music has been used for medicinal purposes throughout history due to its variety of physiological, psychological and social effects. To identify the effects of prenatal music stimulation on the vital signs of pregnant women at full term, on the modification of fetal cardiac status during a fetal monitoring cardiotocograph, and on anthropometric measurements of newborns taken after birth. A randomized controlled trial was implemented. The four hundred and nine pregnant women coming for routine prenatal care were randomized in the third trimester to receive either music (n = 204) or no music (n = 205) during a fetal monitoring cardiotocograph. All of the pregnant women were evaluated by measuring fetal cardiac status (basal fetal heart rate and fetal reactivity), vital signs before and after a fetal monitoring cardiotocograph (maternal heart rate and systolic and diastolic blood pressure), and anthropometric measurements of the newborns were taken after birth (weight, height, head circumference and chest circumference). The strip charts showed a significantly increased basal fetal heart rate and higher fetal reactivity, with accelerations of fetal heart rate in pregnant women with music stimulation. After the fetal monitoring cardiotocograph, a statistically significant decrease in systolic blood pressure, diastolic blood pressure and heart rate in women receiving music stimulation was observed. Music can be used as a tool which improves the vital signs of pregnant women during the third trimester, and can influence the fetus by increasing fetal heart rate and fetal reactivity.

    The normal range of plasma brain natriuretic peptide (BNP) in pregnant women is still unclear. Moreover, pregnant women experience dynamic body weight changes and suffer from anemia, but effects on maternal BNP have not been investigated. This study aimed to reveal the normal plasma BNP range and examine the effects of physiological changes on BNP among pregnant women. Plasma BNP, hemoglobin, plasma creatinine and BMI were measured in 58 non-pregnant control women and in 773 normal pregnant women at late pregnancy, early postpartum and 1-month postpartum. Mean plasma BNP (in pg/mL) was 11.8 (95% confidence interval: 0-27.5) in non-pregnant women, 17.9 (0-44.7, pchange during pregnancy (p=0.001) and post-delivery creatinine (p=0.010) but negatively associated with body weight loss at delivery (pchanges, creatinine and hemoglobin levels; therefore, these factors should be considered when analysing cardiac function and the physiological implications of BNP levels in pregnant women.

    Full Text Available Objectives: The level of dental awareness of a pregnant woman affects the sanitary condition of her own teeth and the health of the child to be born. Poor oral health is considered to be a probable risk factor for the pre-term birth or low birth weight. The aim of this work was to assess the level of oral health knowledge that determines oral health condition of pregnant women in Poland. Material and Methods: Empirical data were obtained from the National Monitoring of Oral Health and Its Determinants, financed by the Ministry of Health. This socio-epidemiological study assessed oral health status and dental health awareness, which affects that status. Study subjects included 1380 pregnant women at the age ranging from 15 to 44, randomly-selected from urban and rural environments. Dental health status was recorded in the clinical examination sheets supplied by the World Health Organization, and the socio-medical data were recorded in the questionnaire interview sheets. Results: Almost 3/4 of the pregnant women evaluated their dental health as unsatisfactory or poor. Over 60% of the pregnant women rated their knowledge and practical skills concerning care of their own teeth and of the child to be born as limited, inadequate or none. Only 40% of the pregnant women provided right answers to the questions about dental issues. Conclusions: Low oral health awareness results in poor oral health status of the study subjects. A statistical pregnant woman has a total of 13 teeth showing the symptoms of tooth decay or caries. Over 70% of the pregnant women developed gingivitis or periodontitis. There is an urgent need in Poland to make the European principle of treating pregnant women as a dentally vulnerable group obligatory.

    Full Text Available Background: Thrombocytopaenia is a common haematologic abnormality during pregnancy. Pregnant women with thrombocytopenia have a higher risk of bleeding excessively during or after childbirth, particularly if they need to have a caesarean section or other surgical intervention during pregnancy, labour or in the puperium. The aim of this study was to determine the prevalence of gestational thrombocytopaenia among pregnant women reporting for antenatal care at tertiary health care centres in Lagos. Materials and Methods: Platelet count was analyzed in 274 consecutive pregnant women who gave informed consent and 70 non-pregnant female staff of the hospitals. Platelet count was performed on each sample using the Sysmex KN-21N automated haematology analyzer. The study design was cross-sectional, proportions were analyzed for statistical significance with the chi-square, and Odds ratio was also calculated. Thrombocytopaenia is classically defined as a platelet count of less than 150 × 10 [9] /L. [3],[4] Counts from 100 to 150 × 10 [9] /L are considered mildly depressed, 50 to 100 × 10 [9] /L are moderately depressed and less than 50 × 10 [9] /L are severely depressed. Results: Thirty-four (13.5% pregnant women were thrombocytopaenic compared with three (4.3% non-pregnant women. This was statistically significant; P = 0.03; Odds ratio: 3.5 (95% CI 1.03-11.82. Out of the 37 pregnant women who were thrombocytopaenic, most of them (78% had mild thrombocytopenia, only 6% had severe thrombocytopaenia. Conclusion: The prevalence of gestational thrombocytopaenia in this study was 13.5%. Although majority of the pregnant women had mild thrombocytopaenia, healthcare providers should screen all pregnant women routinely for thrombocytopaenia to avoid excessive bleeding during or after childbirth.

    Full Text Available Objective(sQuinazolinones are heterocyclic components (able to form cyclized compounds which have several medical effects such as anti-malarial, spasmolytic, anti-microbial, sedative, etc. They are also known for their fungicidal properties, inhibition of tyrosine-kinase and DNA repair enzyme poly (ADP-ribose polymerase (PARP and are also effective in treatment of cancer, diabetes, and parkinsonism complications.Materials and MethodsIn this study, for the first time different aspects of developmental effects of two new Quinazolinone components (QPPE and QEPE, on kidneys of BALB/c mice embryos were investigated. Pregnant BALB/c mice were divided into four groups of control (n=30, sham (n=30, experimental 1 (n=30 and experimental 2 (n=30. Control mice remained intact, sham and two experimental groups received 0.05% methyl cellulose and 100 mg/kg/body weight (most effective dose of QPPE and QEPE, intraperitoneally (IP, on day 10th of gestation. Kidneys were removed by c-sections, stained with H&E, PAS, trichrome, reticholin and jones staining. Some embryonic kidneys were prepared for measurements of level of alkaline phosphatase and TEM studies.ResultsLight and TEM microscopes, and level of enzyme surveys demonstrated that QPPE and QEPE are toxic components, creating protrusions at the surface of convoluted proximal tubules, protein casts, renal necrotic cells, pseudothyroidezation, mitochondria degeneration, hyperemia, glomeruli hypertrophy, widening of renal spaces, vacuolization, as well as decrease in the number of brush border villi and level of alkaline phosphatase. ConclusionBy being teratogens and toxins, these two new derivatives affected development of embryonic kidneys at histological, biochemical and intracellular levels; QEPE had more effects and convoluted proximal tubules were more sensitive than convoluted distal tubules.

    Full Text Available HIV counseling and testing (HCT is a critical gateway to treatment, care, and support services. For pregnant women, it is to access prevention of mother-to-child-transmission (PMTCT services. However, not much has been done to appraise this service from the perspective of the recipients in Nigeria. This study documents the appraisal of the HCT services received at the antenatal care (ANC services in three government hospitals in Ibadan, Nigeria, from the perspectives of pregnant women. Data were collected using focus group discussion guide among purposively selected 40 (21 primigravida and 19 multigravida pregnant women. Observation and inventory checklists were used to collect data on procedures and basic requirements of HCT. Content analysis was used to analyze the data. Participants were neither counseled nor given opportunity to voluntarily participate in HCT services as it was made compulsory before accessing ANC. Test results were reportedly handed over directly to participants without post-test counseling. Observation of HCT procedure showed that guidelines for counseling were not strictly adhered to. Inventory of facilities, staff, and materials revealed inadequate staffing, lack of a dedicated counseling room, and inadequate antiretroviral drugs and test kits. The HCT services as provided for pregnant women are fraught with procedural inadequacies. Training and supervision of health care workers as well as provision of resources are needed to address the situation.

    The aim of this study was to assess the adequacy of prenatal care for pregnant women with hypertension as compared to those at low risk. Adequate management of hypertension and associated factors were also investigated. A cross-sectional study was conducted with 1,947 women, 187 of whom with hypertension, in public prenatal care units in Rio de Janeiro, Brazil, in 2007-2008. Demographic and socioeconomic data, obstetric history, and information on adequacy of prenatal care were collected using interviews and prenatal care cards. Adequacy of management of hypertension was evaluated according to performance of health professionals and health services and women's individual characteristics. Chi-square and multivariate logistic regression were used to compare groups and identify factors associated with management of hypertension. Adequacy of prenatal care was 79% and did not differ between groups. Only 27% of pregnant women with hypertension received appropriate management, with poor professional performance. Hypertensive pregnant women with better prenatal care were those with previous neonatal deaths and/or stillbirths and those with 35 years of age and older. Despite adequate use of prenatal care, management of hypertension in pregnant women was inadequate.

    Objective:To investigate the accuracy of malaria diagnosis among pregnant women admitted in Medani Maternity Hospital, Central Sudan during June-October 2009 and to investigate the antimalarials prescribed in this setting. Methods:Socio-demographic characteristics and obstetrics history were gathered using pre-tested questionnaires. The finger prick blood samples were collected from pregnant women who admitted as malaria case after an initial microscopic test done by general microscopists for malaria diagnosis. The antimalarial treatment prescribed by treating doctor was inquired for. Results:Only 21 (8.6%) out of 243 pregnant women admitted as malaria case after an initial microscopic test done by general microscopists for malaria were found to have blood film positive. There was no significant difference in the specificity of the microscopy accuracy between those who have been investigated in the private and governmental sector, 15/193 (8.2%) vs. 6/60(10%), (P>0.05). Quinine infusion was the prescribed drug in this setting. Conclusions: There is a very poor specificity of malaria microscopy in pregnant women admitted to Madani Maternity Hospital. Quinine was the drug received. Malaria control programme should interfere urgently to change this situation.

    Full Text Available Urinary system stones can be classified according to size, location, X-ray characteristics, aetiology of formation, composition, and risk of recurrence. Especially urolithiasis during pregnancy is a diagnostic and therapeutic challenge. In most cases, it becomes symptomatic in the second or third trimester. Diagnostic options in pregnant women are limited due to the possible teratogenic, carcinogenic, and mutagenic risk of foetal radiation exposure. Clinical management of a pregnant urolithiasis patient is complex and demands close collaboration between patient, obstetrician and urologist. We would like to review current diagnosis and treatment modalities of stone disease of pregnant woman.

    Non-immune pregnant women are at risk of severe measles. As the measles vaccination is contraindicated during pregnancy, women should be vaccinated before conception or during the postpartum period. Nevertheless, measles serology is not recommended during pregnancy in France, and there are no data available concerning measles susceptibility and its associated risk factors among pregnant women. The socio-demographic determinants of measles seronegativity have been identified in a prospective cohort of 826 pregnant women in Paris, France. Measles seronegativity was 10.41% (95% CI 8.32-12.50). Women from higher socio-economic groups, born in France after 1980, were more frequently seronegative.

    We conducted a prospective naturalistic study of pregnant women with bipolar disorder (BD) to evaluate symptoms of BD across childbearing and assess whether pharmacotherapy reduced their severity. Assessments were scheduled at 20, 30, and 36 weeks' gestation and 2, 12, 26, and 52 weeks postpartum. Symptoms were assessed using the Structured Interview Guide for the Hamilton Depression Rating Scale-Atypical Depression Supplement (SIGH-ADS) and Mania Rating Scale (MRS). Pregnant women (N=152) with BD were evaluated; 88 women (58%) were treated and 64 untreated (42%) with psychotropic drugs during pregnancy. Among the 88 women treated, 23 (26%) discontinued their medication in the first trimester and the remaining 65 (74%) were exposed throughout pregnancy or in the second and third trimesters. More than two-thirds (73%) of the women who remained in the study took psychotropic agents postpartum. The mean scores on the SIGH-ADS were in the mild range of depressive symptoms in both the psychotropic-treated and untreated groups in both pregnancy and postpartum. The majority of women had no or few symptoms of mania. Of the pregnant women treated with psychotropic agents, 66% received a guideline-concordant drug, and 34% received either antidepressant monotherapy (for BD I) or mono- or polypharmacy with a variety of other agents. This sample of perinatal women with BD was characterized by mild residual symptoms of depression independent of pharmacotherapy, which poses a risk for recurrence and impaired parenting. The treatment of childbearing women with BD deserves urgent clinical and research attention to improve psychiatric outcomes. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Full Text Available Background: Previous studies have shown that morphine consumption during pregnancy may delay embryo development or cause abnormal nervous system function. Objective: The present study focused on the effect of maternal morphine consumption on development of placenta and blood corticosteron concentration in addictive pregnant mothers.Materials and Methods: 24 female rats, 170-200g weight, were used. The experimental groups after pregnancy received an oral dose of 0.05 mg/ml of morphine by tap water while the control group received only tap water. On 10th and 14th day of pregnancy, rats were anesthetized and placenta removed surgically, 1ml blood was collected from each pregnant mother from retro-orbital sinus, the concentration of blood corticosteron was determined by corticosteron Elisa kit after centrifugation. The fixed tissue was processed, sectioned and stained with hematoxylin and eosin. Placenta was studied microscopically according to the thickness of layers, area of blood cisterns, and the number of cells.Results: Comparing the plasma corticosteron concentration of the treatment and the control groups, not only a severe increase in the treatment group was detected, but also the thickness of maternal and embryonic portions of the placenta at day 10th and 14th of gestation was different significantly (p≤0.05. Furthermore, an increase in number of cells in maternal and embryonic portion of placenta and a decrease in blood cistern area were demonstrated in both the experimental and the control groups.Conclusion: The effects of morphine, including an increase in blood concentration of corticosteron, in dependent pregnant mothers were seen. Development of placenta in the experimental group was delayed.

    Marijuana is the most commonly used illicit substance in pregnancy. Little is known about how pregnant women who use marijuana obtain and understand information about perinatal marijuana use. We conducted a qualitative study among pregnant women who had used marijuana to understand their information-seeking patterns and perceptions of usefulness of available information about perinatal marijuana use. We conducted semistructured interviews with 26 pregnant women who were receiving prenatal care and who either disclosed marijuana use or had urine samples testing positive for marijuana. Interviews assessed women's sources of information about risks of perinatal marijuana use and perceptions regarding the usefulness of such information. Interview data were coded independently by two coders who iteratively refined the codes and reviewed transcripts for themes. Commonly reported sources of information about perinatal marijuana use included Internet searching and anecdotal experiences or advice from family or friends. Few women reported receiving helpful information from a health care provider or social worker. Women perceived a lack of evidence about harms of perinatal marijuana use, and reported being dissatisfied with the quality of information. Most women said they desired information about the effects of perinatal marijuana use on infant health. Women who used marijuana before or during pregnancy did not find available information about perinatal marijuana use to be useful, and sought more information pertaining to infant health and well-being. Efforts to reduce perinatal marijuana use should focus on addressing this need in both clinical and public health settings. Copyright © 2016 Jacobs Institute of Women's Health.

    Full Text Available Heterotopic grafting sites can be useful in producing oocytes for in vitro Fertilization, therefore, maximising the oocyte yield from the graft by gonadotrophin stimulation would be advantageous. The aim of this study was to investigate the number and quality of oocytes collected from heterotopic autografted ovary after Pregnant Mare Serum Gonadothropin (PMSG induction. Graft recipients were treated either with or without PMSG stimulation 48 hours prior to graft collection. Ovarian tissue from four weeks old mice (DDY strain were autotransplanted under the kidney capsule of the same ovariectomized mice and the oocytes were collected 21 days after autotransplantation. The results showed that the average number of oocytes collected from autografted ovaries without PMSG induction were 9.0. + 2.8 not significantly different with those received PMSG induction, 10.9 + 5.1. The percentage of matured and fertilized oocytes and the developed embryos from the autografted ovaries without PMSG induction were 52.4, 33.4, and 26.0%, respectively not significantly different with those received PMSG induction, 53.2, 35.1, and 29.9%, respectively. The number of oocytes and the capacity to matured, fertilized and developed were significantly lower (P < 0.05 compared to the superovulated nongrafted (control ovaries. In conclusion, PMSG induction on the graft recipients did not significantly increase oocytes yield from grafted heterotopic ovaries. The number and quality of oocytes produced from the autografted ovaries were lower than the superovulated nongrafted ovaries, but still can be used for in vitro embryo production after sequential in vitro maturation and fertilization.

    Recently, we showed that following pregnancy and 6 months of lactation, adolescents cease linear growth and have reduced fat and lean mass in rural Bangladesh. Here, we examined whether these changes varied by pregnancy outcomes such as fetal loss, low birthweight (LBW) and neonatal mortality. Anthropometric measurements were taken among 12-19-year-old primigravidae (n = 229) in early pregnancy and at 6 months post-partum. Never-pregnant adolescents (n = 456) matched on age and time since menarche were also measured at the same time. Change in anthropometry among pregnant vs. never-pregnant adolescents was compared by pregnancy outcome adjusting for confounders using mixed effects regression models. Pregnant girls, irrespective of birth outcome, did not gain in stature, while never-pregnant girls increased in height by 0.36 +/- 0.04 cm year(-1) (P Body mass index, mid-upper arm circumference (MUAC) and % body fat among pregnant adolescents whose infants survived the neonatal period had decreased at 6 months post-partum, whereas those who experienced a fetal loss or neonatal death did not change in any of the measurements. Consequently, the difference in change in ponderal size and body composition measures between pregnant and never-pregnant girls was higher among those whose neonates survived vs. those who experienced a fetal loss/neonatal death (BMI: -0.64 +/- 0.11 vs. 0.01 +/- 0.16 kg m(-2) year(-1); MUAC: -0.96 +/- 0.12 vs. -0.35 +/- 0.17 cm year(-1), both P pregnant girls regardless of birth outcome. Maternal weight loss and depletion of fat and lean mass at 6 months post-partum were more pronounced when the infants survived through the neonatal period.

A software-defined radio (SDR) implementation allows a single hardware element to function as either a conventional radio or as a GPS receiver, providing backup and redundancy for platforms such as the International Space Station (ISS) and high-value remote sensing platforms. The innovation's flexible SDR implementation reduces cost, weight, and power requirements. Scintillation hardening improves mission reliability and variability. In Phase I, CommLargo refactored an open-source GPS software package with Kalman filter-based tracking loops to improve performance during scintillation and also demonstrated improved navigation during a geomagnetic storm. In Phase II, the company generated a new field-programmable gate array (FPGA)-based GPS waveform to demonstrate on NASA's Space Communication and Navigation (SCaN) test bed.

    The luxury of PIP is gone and managing cash flow will become more important than ever before. The hospital industry has come a long way in the development of automated billing systems and related recordkeeping since PIP was first introduced. The performance of an operations review of the accounts receivable management system should improve the effectiveness and efficiency of operations and significantly improve cash flow.

  6. Diversity of MMSE MIMO Receivers

    Mehana, Ahmed Hesham

    2011-01-01

    In most MIMO systems, the family of waterfall error curves, calculated at different spectral efficiencies, are asymptotically parallel at high SNR. In other words, most MIMO systems exhibit a single diversity value for all {\\em fixed} rates. The MIMO MMSE receiver does not follow this pattern and exhibits a varying diversity in its family of error curves. This effect cannot be captured by DMT analysis, due to the fact that all fixed rates correspond to the same multiplexing gain, thus they cannot be differentiated within DMT analysis. This work analyzes this interesting behavior of the MMSE MIMO receiver and produces the MMSE MIMO diversity at each rate. The diversity of the quasi-static flat-fading MIMO channel consisting of any arbitrary number of transmit and receive antennas is fully characterized, showing that full spatial diversity is possible for all antenna configurations if and only if the rate is within a certain bound which is a function of the number of antennas. For other rate brackets, the avail...

  7. Orexin neurons receive glycinergic innervations.

    Directory of Open Access Journals (Sweden)

    Mari Hondo

    Full Text Available Glycine, a nonessential amino-acid that acts as an inhibitory neurotransmitter in the central nervous system, is currently used as a dietary supplement to improve the quality of sleep, but its mechanism of action is poorly understood. We confirmed the effects of glycine on sleep/wakefulness behavior in mice when administered peripherally. Glycine administration increased non-rapid eye movement (NREM sleep time and decreased the amount and mean episode duration of wakefulness when administered in the dark period. Since peripheral administration of glycine induced fragmentation of sleep/wakefulness states, which is a characteristic of orexin deficiency, we examined the effects of glycine on orexin neurons. The number of Fos-positive orexin neurons markedly decreased after intraperitoneal administration of glycine to mice. To examine whether glycine acts directly on orexin neurons, we examined the effects of glycine on orexin neurons by patch-clamp electrophysiology. Glycine directly induced hyperpolarization and cessation of firing of orexin neurons. These responses were inhibited by a specific glycine receptor antagonist, strychnine. Triple-labeling immunofluorescent analysis showed close apposition of glycine transporter 2 (GlyT2-immunoreactive glycinergic fibers onto orexin-immunoreactive neurons. Immunoelectron microscopic analysis revealed that GlyT2-immunoreactive terminals made symmetrical synaptic contacts with somata and dendrites of orexin neurons. Double-labeling immunoelectron microscopy demonstrated that glycine receptor alpha subunits were localized in the postsynaptic membrane of symmetrical inhibitory synapses on orexin neurons. Considering the importance of glycinergic regulation during REM sleep, our observations suggest that glycine injection might affect the activity of orexin neurons, and that glycinergic inhibition of orexin neurons might play a role in physiological sleep regulation.

    The management of acne vulgaris in the setting of pregnancy raises important clinical considerations regarding the efficacy and safety of acne treatments in this special patient population. Particular challenges include the absence of safety data, discrepancy in safety data between different safety rating systems, and lack of evidence-based recommendations for the treatment of acne during pregnancy. Nonetheless, many therapeutic options exist, and the treatment of acne in pregnant women can be safely and often effectively accomplished. For mild or moderate disease, patients can be treated with topical antimicrobial agents, anti-inflammatory agents, as well as glycolic and salicylic acid. Several topical agents, notably benzoyl peroxide, previously viewed as potentially dangerous are cited by many sources as being considered safe. When necessary, systemic therapies that can be safely added include penicillins, amoxicillin, cephalosporins, erythromycin, clindamycin, and tetracyclines or sulfonamides, depending on the stage of fetal development. Adjunct therapy may include phototherapy or laser treatments. Physicians should work with this often highly motivated, safety-conscious patient population to tailor an individualized treatment regimen. This treatment regimen will likely shift throughout the different stages of fetal development, as distinct safety considerations are raised prior to conception as well as during each of the trimesters of pregnancy. Important considerations regarding acne management in breast-feeding mothers is also discussed.

    Full Text Available OBJECTIVE: In this study we aim to characterize a sample of 85 pregnant crack addicts admitted for detoxification in a psychiatric inpatient unit. METHOD: Cross-sectional study. Sociodemographic, clinical, obstetric and lifestyle information were evaluated. RESULTS: Age of onset for crack use varied from 11 to 35 years (median = 21. Approximately 25% of the patients smoked more than 20 crack rocks in a typical day of use (median = 10; min-max = 1-100. Tobacco (89.4%, alcohol (63.5% and marijuana (51.8% were the drugs other than crack most currently used. Robbery was reported by 32 patients (41.2%, imprisonment experience by 21 (24.7%, trade of sex for money/drugs by 38 (44.7%, home desertion by 33 (38.8%; 15.3% were positive for HIV, 5.9% for HCV, 1.2% for HBV and 8.2% for syphilis. After discharge from the psychiatric unit, only 25% of the sample followed the proposed treatment in the chemical dependency outpatient service. CONCLUSION: Greater risky behaviors for STD, as well as high rates of maternal HIV and Syphilis were found. Moreover, the high rates of concurrent use of other drugs and involvement in illegal activities contribute to show their chaotic lifestyles. Prevention and intervention programs need to be developed to address the multifactorial nature of this problem.

    The hemoglobin concentrations during pregnancy in Filipinos belonging to the upper income group, who were prescribed 105 mg elemental iron daily, and who had acceptable levels of transferrin saturation, were examined in an attempt to define normal levels. The hemoglobin concentrations for each trimester followed a Gaussian distribution. The hemoglobin values equal to the mean minus one standard deviation were 11.4 gm/dl for the first trimester and 10.4 gm/dl for the second and third trimesters. Using these values as the lower limits of normal, in one group of pregnant women the prevalence of anemia during the last two trimesters was found lower than that obtained when WHO levels for normal were used. Groups of women with hemoglobin of 10.4 to 10.9 gm/dl (classified anemic by WHO criteria but normal in the present study) and those with 11.0 gm/dl and above could not be distinguished on the basis of their serum ferritin levels nor on the degree of decrease in their hemoglobin concentration during pregnancy. Many subjects in both groups, however, had serum ferritin levels less than 12 ng/ml which indicate poor iron stores. It might be desirable in future studies to determine the hemoglobin cut-off point that will delineate subjects who are both non-anemic and adequate in iron stores using serum ferritin levels as criterion for the latter.

    2012-01-01

    Pregnancy results in a lot of hormonal changes in the body and the eyes are no exception. These ocular changes could be physiologic, pathologic or a modification of a pre-existing condition. The aim of this study was to determine physiologic ocular changes that are associated with pregnancy in healthy Nigerian women. A total of 100 women were followed longitudinally through out the course of their pregnancy and 6 weeks postpartum. The women were recruited at 8 weeks of pregnancy at the anti-natal clinic in the Department of Obstetrics and Gynecology, University of Benin Teaching Hospital, Nigeria. The women were aged between 20 and 35 years. Tests carried out included visual acuity, ophthalmoscopy, retinoscopy, and tonometry. The tests were carried out in each of the three trimesters of pregnancy and 6 weeks postpartum. There was a fall in intraocular pressure across the trimesters and this was very significant (Pchanges associated with pregnancy are transient and most tend to resolve postpartum, with values returning to near pre-pregnant state.

    1993-09-01

    Logistic regressions were used to analyze consistency in decision making about adoption and parenting among 162 pregnant adolescents aged 12-23 years in a Crittenton Services facility. Eight hypotheses were generated about the determinants of adoption or parenting. For instance, external locus of control and lower self-esteem were expected to lower the odds of being consistent in planning for adoptions. Significant others' influence in support of adoption increases the odds of consistency. Residents have the opportunity to participate in small group educational efforts which emphasize adoption as a viable alternative and receive general counseling help in planning a realistic postpartum plan for parenting. Age, ethnicity, education, and reproductive history were considered background variables. Nowicki and Strickland's Control Scale for Children, Coopersmith's Self-Esteem Inventory, and McMaster's Family Assessment Device were used to measure social psychological variables. Social influence measures pertained to communication with and preference of the mother and the birth father. The dependent measures were the initial adoption plan and consistency with or switching of the initial adoption plan. The results reveal that equal numbers initially planned to adopt and to parent. Each group had similar background characteristics, with the exception that most adoption acceptors lived at home, and those who chose parenting were in the custody of a public agency. About 20% switched decisions over time. One teenager switched from parenting to adoption, and 32 (19.8%) switched from adoption to parenting. Of the 16 predictors, only social influence variables had clear significant effects. Mother's preference for adoption was the strongest influence on decision making. Only the birth father's preference strongly influenced the plan to adopt, by tripling the odds of consistency of adoption. Agreement between the mother and the birth father on adoption increased the odds of a

    When pregnant mice were given small doses of teratogens (cytosine arabinoside, mitomycin C, or busulfan) that did not induce anomalies of any other organs, a high incidence of carpal and tarsal bone anomalies still occurred. The carpal and tarsal bones may be used as a sensitive target for teratogenicity testing.

    This study described the nutritional status of 228 pregnant women and the influence of this on birth weight. This is a retrospective study, developed in a health center in the municipality of São Paulo, with data obtained from medical records. Linear regression analysis was carried out. An association was verified between the initial and final nutritional status (ppregnancy underweight was higher compared those who started overweight/obese (p=0.005). Weight gain was insufficient for 43.4% of the pregnant women with adequate initial weight and for 36.4% of all the pregnant women studied. However, 37.1% of those who began the pregnancy overweight/obese finished with excessive weight gain, a condition that ultimately affected almost a quarter of the pregnant women. Anemia and low birth weight were uncommon, however, in the linear regression analysis, birth weight was associated with weight gain (pnutritional care before and during pregnancy to promote maternal-infant health.

  18. Wireless fetal heart rate monitoring in inpatient full-term pregnant women: testing functionality and acceptability.

    Directory of Open Access Journals (Sweden)

    Adeline A Boatin

    Full Text Available We tested functionality and acceptability of a wireless fetal monitoring prototype technology in pregnant women in an inpatient labor unit in the United States. Women with full-term singleton pregnancies and no evidence of active labor were asked to wear the prototype technology for 30 minutes. We assessed functionality by evaluating the ability to successfully monitor the fetal heartbeat for 30 minutes, transmit this data to Cloud storage and view the data on a web portal. Three obstetricians also rated fetal cardiotocographs on ease of readability. We assessed acceptability by administering closed and open-ended questions on perceived utility and likeability to pregnant women and clinicians interacting with the prototype technology. Thirty-two women were enrolled, 28 of whom (87.5% successfully completed 30 minutes of fetal monitoring including transmission of cardiotocographs to the web portal. Four sessions though completed, were not successfully uploaded to the Cloud storage. Six non-study clinicians interacted with the prototype technology. The primary technical problem observed was a delay in data transmission between the prototype and the web portal, which ranged from 2 to 209 minutes. Delays were ascribed to Wi-Fi connectivity problems. Recorded cardiotocographs received a mean score of 4.2/5 (± 1.0 on ease of readability with an interclass correlation of 0.81(95%CI 0.45, 0.96. Both pregnant women and clinicians found the prototype technology likable (81.3% and 66.7% respectively, useful (96.9% and 66.7% respectively, and would either use it again or recommend its use to another pregnant woman (77.4% and 66.7% respectively. In this pilot study we found that this wireless fetal monitoring prototype technology has potential for use in a United States inpatient setting but would benefit from some technology changes. We found it to be acceptable to both pregnant women and clinicians. Further research is needed to assess feasibility of

    Infection with Clostridium difficile has been shown to have particularly poor outcomes for pregnant women, including an increased risk of death. The purpose of this study was to investigate the prevalence, genotypic distribution, and characterization of C. difficile strains isolated from pregnant women without diarrhea in China. As part of this study, 3.7% (37 out of 1009) of samples acquired from pregnant females tested positive for C. difficile. Of these positive samples, 27.0% (10) were toxigenic isolates containing both toxin A and toxin B genes (A+B+), 13.5% (5) of the variant strains contained the toxin B gene (A-B+) only, while the rest were non-toxigenic isolates (59.5%, 22 isolates). Among the non-pregnant women without diarrhea tested, 1.4% (9 of 651) contained toxigenic isolates (all of which were A+B+). Sixteen different sequence types (STs) were isolated during the course of this study. ST-37 (ribotype 017) and ST-54 (ribotype 012) were the most frequent toxigenic types observed in pregnant women. All strains showed susceptibility to the antibiotics metronidazole and vancomycin. The resistance rates of toxigenic C. difficile strains isolated from pregnant females to clindamycin, erythromycin, moxifloxacin, levofloxacin, and rifampicin were 20%, 46.7%, 13.6%, 46.7% and 13.3%, respectively. There was no significant difference between resistance rates of toxigenic and non-toxigenic strains with respect to their susceptibility to these antibiotics. However, when compared with the same data from non-pregnant women, toxigenic strains from pregnant women showed lower resistance rates to clindamycin (P < 0.05). Copyright © 2016 Elsevier Ltd.

Sixty-four pregnant women receiving prenatal care underwent an oral glucose tolerance test at 20-24 weeks of gestation and an insulin release test. The GDM group included 34 pregnant women diagnosed with gestational impaired glucose tolerance or GDM, and the subjects with normal blood glucose were the control group. Insulin resistance and islet β-cell function changes were observed with the oral glucose tolerance test and insulin release test. The homeostatic model assessment-β levels in late pregnancy were higher than those in mid-pregnancy for both groups, and the primary time effect was statistically significant. The early insulin secretion index (ΔI(30)/ΔG(30)) values in mid- and late pregnancy were lower in the GDM group. The values of the area under the curve of blood glucose in mid- and late pregnancy were higher in the GDM group than those in the control group. Insulin resistance was higher in GDM patients than in normal pregnant women. Insulin resistance was aggravated, and β-cell's ability to compensate for the increased insulin resistance by modulating insulin secretion was aggravated, as gestational week increased in women with gestational diabetes and normal pregnant women. Insulin resistance in women with GDM is higher than in pregnant women with normal metabolism of glucose. © 2012 The Authors.

    To evaluate the macular, retinal nerve fiber layer (RNFL) and choroidal thickness alterations by using spectral-domain optical coherence tomography (SD-OCT) in preeclampsia and compare with healthy pregnant and healthy non-pregnant controls. The study population included healthy pregnant control group (n: 25), healthy non-pregnant control group (n: 26) and study group with preeclampsia (n: 27). Retinal thickness parameters were measured by SD-OCT. There was a statistically significant difference among all of the groups for choroidal thickness (p Choroidal thickness in preeclamptic women was significantly thinner than healthy pregnant women. The most thick choroid layer was detected in healthy pregnant group, and also the most thin choroidal thickness was detected in healthy non-pregnant group (p thickness were significantly thinner in preeclamptic study and healthy pregnant groups than healthy non-pregnant group (p thickness. Average of RNFL thickness was significantly thicker in healthy pregnant group than healthy non-pregnant group (p = 0.004). This study revealed that choroidal thickness measured using SD-OCT increased in women with preeclampsia and healthy pregnant women but the increase in choroidal thickness in preeclampsia was lower than the healthy pregnant controls. This lower rise in choroidal thickness can be generally attributed to the markedly increased systemic vascular vasospasm secondary to preeclampsia.

    Full Text Available Background and Objectives. Pregnancy triggers a wide range of changes in a woman’s body leading to various musculoskeletal dysfunctions. Most commonly reported musculoskeletal discomforts by pregnant women are low back pain and symphysis pubis pain. The culture and the environmental factors may influence the discomforts experienced by a pregnant woman. There is a dearth of literature in India, regarding the common musculoskeletal dysfunctions experienced by a pregnant woman, and hence this study. Method. A questionnaire to identify the musculoskeletal dysfunction was developed; content was validated and was translated to local languages through parallel back translation. 261 primiparous pregnant women participated in the study and filled the questionnaire in their native language. Results. Among the musculoskeletal dysfunctions reported by the pregnant women, 64.6% reported calf muscle cramps, 37.1% reported foot pain, and 33.7% experienced low back pain in their third trimester. In the second trimester, common musculoskeletal dysfunctions experienced by the women were that of calf pain (47.8%, low back pain (42%, and pelvic girdle pain (37%. Conclusion. Musculoskeletal dysfunctions and general discomforts very commonly affect the activities of daily living of pregnant women. Understanding the common discomforts during various trimesters of pregnancy will help to develop a comprehensive program for prevention and cure.

    Clinical research in the pregnant population allows for delivery of quality, evidence-based care in obstetrics. However, in recent years, the field of obstetrics has faced severe challenges in the recruitment of the pregnant population into clinical trials, a struggle also shared by several other medical disciplines. We candidly describe our failure to recruit a healthy population of overweight and obese pregnant women in their first trimester. We were then able to glean unsuccessful and successful recruitment approaches and improve our recruitment effort by autopsy of failed strategies and with guidance from a survey disseminated to improve our understanding of community feelings about participating in research while pregnant. These "lessons learned" taught us that active recruitment within this population is a necessity; that is, direct (face-to-face discussions at obstetric appointments) compared with indirect (flyers and general emails) modalities and that prenatal care provider support of the proposed research study is vital to a patient's willingness to participate. By implementation of "lessons learned," we describe how we successfully recruited a similar pregnant population 1 year later. The Clinical Trials related to our article are as follows: 1) Expecting Success: NCT01610752, https://clinicaltrials.gov/ct2/show/NCT01610752; 2) MomEE: NCT01954342, https://clinicaltrials.gov/ct2/show/NCT01954342; and 3) Participate While Pregnant Survey: NCT02699632, https://clinicaltrials.gov/ct2/show/NCT02699632.

    Full Text Available Introduction. Monitoring of the environmental differences in the mode of nutrition is especially important in pregnant women, for whom normal body weight gain is especially important for both the course of pregnancy and the normal development of the foetus, and is inseparably associated with rational nutrition. Objective. The objective of the study was evaluation of the mode of nutrition of pregnant women according to the place of residence. Materials and methods. The investigation comprised 704 women. Information was collected by means of an anonymous survey concerning place of residence, consumption of selected products and beverages, and taking folic acid and other vitamin and/or mineral dietary supplements. Results. In the urban environment, pregnant women more frequently consumed vegetables, milk and dairy products, sea fish and wholemeal cereal products, drank more liquids, as well as more fruit and/or vegetable juices, and more often used the supplementation with folic acid, even before becoming pregnant. No significant differences were found in the consumption of fruits, pulses, products which are the source of complete proteins, confectionery products and sweets, according to the place of residence. Conclusions. The diet of pregnant women from the rural environment compared to that of women from urban areas, was characterized by worse quality. It is necessary to carry out health education in the area of adequate nutrition among pregnant women, and those who plan pregnancy, directed primarily to all women from the rural environment.

    Full Text Available Asthma and gastroesophageal reflux disease (GERD are two common problems in pregnancy and they affect pregnancy in several ways. In this study, we aimed to evaluate GERD and asthma in pregnant women who referred for prenatal care visits. One-hundred and seventy three pregnant women with a complaint of dyspnea were included in the study. A questionnaire was filled and lung function tests were performed. All patients were visited by a respiratory specialist and questionnaires were evaluated by a gastroenterologist. Out of the total number of women studied, 37% were diagnosed to have asthma and 36.4% were non-asthmatics. Twenty six percent of the pregnant women who had symptoms and signs of asthma with normal spirometry were classified as probable to have asthma. GERD was diagnosed in 80.9% of the pregnant women, but it was not significantly higher in asthmatic or probable asthmatic women compared to non-asthmatic ones. However, severity of GERD was significantly higher in asthmatic pregnant women compared to the others. In conclusion, the prevalence of GERD was quite high in pregnant women, irrespective of the fact that they were asthmatic or non-asthmatic. Further studies evaluating women throughout pregnancy will inform us more about this relationship.

    Promoting healthy gestational weight gain (GWG) is important for preventing obstetric and perinatal morbidity, along with obesity in both mother and child. Provision of GWG guidelines by health professionals predicts women meeting GWG guidelines. Research concerning women's GWG information sources is limited. This study assessed pregnant women's sources of GWG information and how, where and which women seek GWG information. Consecutive women (n = 1032) received a mailed questionnaire after their first antenatal visit to a public maternity hospital in Melbourne, Australia. Recalled provision of GWG guidelines by doctors and midwives, recalled provided GWG goals, and the obtaining of GWG information and information sources were assessed. Participants (n = 368; 35.7% response) averaged 32.5 years of age and 20.8 weeks gestation, with 33.7% speaking a language other than English. One in ten women recalled receiving GWG guidelines from doctors or midwives, of which half were consistent with Institute of Medicine guidelines. More than half the women (55.4%) had actively sought GWG information. Nulliparous (OR 7.07, 95% CI = 3.91-12.81) and obese (OR 1.96, 95% CI = 1.05-3.65) women were more likely to seek information. Underweight (OR 0.29, 95% CI = 0.09-0.97) women and those working part time (OR 0.52, 95% CI = 0.28-0.97) were less likely to seek information. Most frequently reported GWG sources included the internet (82.7%), books (55.4%) and friends (51.5%). The single most important sources were identified as the internet (32.8%), general practitioners (16.9%) and books (14.9%). More than half of women were seeking GWG guidance and were more likely to consult non-clinician sources. The small numbers given GWG targets, and the dominance of non-clinical information sources, reinforces that an important opportunity to provide evidence based advice and guidance in the antenatal care setting is currently being missed.

    Instrument errors made negligible. For each integration interval, both delay and rate of change of delay initialized to small fraction of chip - for example, to order of 10 to the negative 7th power - thereby making feedback control and extraction of delay highly accurate and flexible. With appropriate selection of sampling rate relative to chip rate, commensurability errors reduced to extremely small levels. In Global Positioning System (GPS) receiver, pseudorandom code sequence generated by simple digital logic incorporating effects of time, delay, and rate of change of delay. Flexibility in starting time and sum interval very useful in aligning correlation interval with beginnings and endings of data bits.

    Full Text Available Introduction: Pregnancy can be associated with different psychological problems such as depression and anxiety. These problems are often neglected and left untreated. This study aimed to examine the effect of mindfulness-integrated cognitive behavior therapy on depression and anxiety among pregnant women. Methods: A convenient sample of 80 pregnant women were selected. Participants were randomly allocated to either the experimental or the control groups. Participants in the experimental group received mindfulness-integrated cognitive behavior therapy while women in the control group only received routine prenatal care services. A demographic questionnaire, the Edinburgh Postnatal Depression Scale, and the Beck Anxiety Inventory were used for data collection. Descriptive statistics measures such as frequency, mean, and standard deviation as well as the repeated-measures analysis of variance test were used for data analysis. Results: After the study intervention, the mean scores of anxiety and depression in the experimental group were significantly lower than the control group. Conclusion: Mindfulness-integrated cognitive behavior therapy can significantly alleviate pregnant women’s depression and anxiety. So implementation of this method alongside with other prenatal care services is recommended.

  18. Palatable meal anticipation in mice.

    Directory of Open Access Journals (Sweden)

    Cynthia T Hsu

    Full Text Available The ability to sense time and anticipate events is a critical skill in nature. Most efforts to understand the neural and molecular mechanisms of anticipatory behavior in rodents rely on daily restricted food access, which induces a robust increase of locomotor activity in anticipation of daily meal time. Interestingly, rats also show increased activity in anticipation of a daily palatable meal even when they have an ample food supply, suggesting a role for brain reward systems in anticipatory behavior, and providing an alternate model by which to study the neurobiology of anticipation in species, such as mice, that are less well adapted to "stuff and starve" feeding schedules. To extend this model to mice, and exploit molecular genetic resources available for that species, we tested the ability of wild-type mice to anticipate a daily palatable meal. We observed that mice with free access to regular chow and limited access to highly palatable snacks of chocolate or "Fruit Crunchies" avidly consumed the snack but did not show anticipatory locomotor activity as measured by running wheels or video-based behavioral analysis. However, male mice receiving a snack of high fat chow did show increased food bin entry prior to access time and a modest increase in activity in the two hours preceding the scheduled meal. Interestingly, female mice did not show anticipation of a daily high fat meal but did show increased activity at scheduled mealtime when that meal was withdrawn. These results indicate that anticipation of a scheduled food reward in mice is behavior, diet, and gender specific.

    In this study, we aimed to compare the Syrian refugees and resident Turkish pregnant population in terms of Toxoplasma seroprevalence. Data acquired from Kahramanmaraş Necip Fazıl City Hospital Department of Obstetrics and Gynecology between 2012 and 2013 were analyzed retrospectively. Results of 7201 Toxoplasma IgM tests and 4113 Toxoplasma IgG tests were evaluated. For 2012 and 2013 Toxoplasma IgM seropositivity was found in Syrian refugees 4.76% and 4.84% respectively in our study. In the same population Toxoplasma IgG seropositivity rates were 80% and 62.6%, respectively. Toxoplasma IgM seropositivity rates for the native peoples in Turkey in 2012 and 2013 was 1.96% and 2.34%, while in the same population Toxoplasma IgG seropositivity was detected 49.7% and 45.7% respectively. Toxoplasma IgM seropositivity was statistically higher in Syrian refugees for each year (p refugees was statistically higher (p refugees living in the region of Kahramanmaraş were statistically higher than the rates of local inhabitants, we consider that this condition should be taken into account in the follow-ups of Syrian pregnant refugees outnumbering in Kahramanmaraş and its vicinity.

    Maternal malnutrition is a worldwide public health problem affecting a high proportion of pregnant women. This study aimed to determine the magnitude and determinants of malnutrition among pregnant women in eastern Ethiopia. A cross-sectional study was conducted on 1731 pregnant women selected by a cluster random sampling method. Data on maternal anthropometry and other factors were gathered by trained data collectors. Mid-upper arm circumference malnutrition. Mixed-effect, multilevel logistic regression was used to control clustering effect. On average, 19.06% of subjects were malnourished, while 23.3% study participants were underweight (body mass index malnutrition was more than twofold higher in pregnant women with low (adjusted odds ratio = 2.47, 95% confidence interval = 1.41-4.34) and medium (adjusted odds ratio = 2.74, 95% confidence interval = 1.40-5.35) autonomy of household decision-making than those who had high level of autonomy in household decision-making. Husband illiteracy and not owning livestock were associated with increased risk of malnutrition. Women in the second and third trimester had a 66% and nearly twofold increased risk of malnutrition compared with their counterparts in the first trimester, respectively. Women who improved their eating habits had a 53% lower risk of malnutrition than those who did not. The risk of malnutrition was 39% lower in respondents who received prenatal dietary advice than in those who did not. Malnutrition affects at least one of every five pregnant women studied, calling for priority attention. Interventions that improve maternal involvement in household decision-making autonomy and provision of prenatal dietary advice are recommended. © 2014 John Wiley & Sons Ltd.

    Objectives Prenatal psychosocial stress has been associated with adverse pregnancy outcomes, even after controlling for known risk factors. This paper aims to evaluate correlates of high perceived stress among Hispanic women, a group with elevated rates of stress during pregnancy. Methods We conducted this analysis among 1426 pregnant Hispanic women using data from Proyecto Buena Salud, a prospective cohort study conducted in Western Massachusetts. Cohen’s Perceived Stress Scale (PSS-14) validated in English and Spanish was administered in early (mean=12.4 wks gestation), mid (mean=21.3 wks gestation) and late (mean=30.8 wks gestation) pregnancy at which time bilingual interviewers collected data on socio-demographic, acculturation, behavioral, and psychosocial factors. High perceived stress was defined as a PSS score>30. Results Young maternal age (odds ratio (OR) =0.6; 95% confidence interval (CI) 0.4-0.9 for 12 drinks/mo. vs. none) and smoking (OR=2.2; 95% CI 1.3-3.7 for >10 cigarettes/day vs. none) were associated with high perceived stress during early pregnancy. Furthermore, higher annual household income (OR=0.4; 95% CI 0.1-0.9 for >$30,000 vs. <$15,000), greater number of adults in the household (OR=1.8; 95% CI 1.1-3.0 for ≥3 vs. 1) and language preference (OR=0.6; 95% CI 0.4-0.9 for Spanish vs. English) were associated with high stress during mid-pregnancy. Likewise, annual household income was inversely associated with high stress during late pregnancy. Conclusion Our results have important implications for incorporation of routine screening for psychosocial stress during prenatal visits and implementation of psychosocial counseling services for women at high risk.

    This book discusses the trade-offs involved in designing direct RF digitization receivers for the radio frequency and digital signal processing domains.  A system-level framework is developed, quantifying the relevant impairments of the signal processing chain, through a comprehensive system-level analysis.  Special focus is given to noise analysis (thermal noise, quantization noise, saturation noise, signal-dependent noise), broadband non-linear distortion analysis, including the impact of the sampling strategy (low-pass, band-pass), analysis of time-interleaved ADC channel mismatches, sampling clock purity and digital channel selection. The system-level framework described is applied to the design of a cable multi-channel RF direct digitization receiver. An optimum RF signal conditioning, and some algorithms (automatic gain control loop, RF front-end amplitude equalization control loop) are used to relax the requirements of a 2.7GHz 11-bit ADC. A two-chip implementation is presented, using BiCMOS and 65nm...

    Full Text Available Background: Smoking is considered the most important preventable risk factor in relation to the development of complications during pregnancy and delivery. The aim of this study was to evaluate the effectiveness of an intensive 6-week gold standard programme (GSP on pregnant women in real life. Methods: This was a prospective cohort study based on data from a national Danish registry on smoking cessation interventions. The study population included 10,682 women of a fertile age. The pregnancy status of the study population was identified using the National Patient Registry. Results: The response rate to follow up was 76%. The continuous abstinence rate for both pregnant and non-pregnant smokers was 24–32%. The following prognostic factors for continuous abstinence were identified: programme format (individual/group, older age, heavy smoking, compliance with the programme, health professional recommendation, and being a disadvantaged smoker. Conclusions: The GSP seems to be as effective among pregnant smokers as among non-pregnant smoking women. Due to the relatively high effect and clinical significance, the GSP would be an attractive element in smoking cessation intervention among pregnant women.

    Full Text Available Background/aim: Ureaplasma urealyticum, a common commensal of the female lower genital tract, has been observed as an important opportunistic pathogen during pregnancy. The aims of this study were to determine the degree of cervical colonization with U. urealyticum in pregnant women with risk pregnancy and in pregnant women with normal term delivery and to evaluate the correlation between high-density cervical U. urealyticum colonization and premature rupture of membranes (PROM as well. Methods. This research was conducted on the samples comprising 130 hospitalized pregnant women with threatening preterm delivery and premature rupture of membranes. The control group consisted of 39 pregnant women with term delivery without PROM. In addition to standard bacteriological examination and performing direct immunofluorescence test to detect Chlamydia trachomatis, cervical swabs were also examined for the presence of U. urealyticum and Mycoplasma hominis by commercially available Mycofast Evolution 2 test (International Microbio, France. Results. The number of findings with isolated high-density U. urealyticum in the target group was 69 (53.08%, while in the control group was 14 (35.90%. Premature rupture of membranes (PROM occurred in 43 (33.08% examinees: 29 were pPROM, and 14 were PROM. The finding of U.urealyticum ≥104 was determined in 25 (58.14% pregnant women with rupture, 17 were pPROM, and 8 were PROM. There was statistically significant difference in the finding of high-density U. urealyticum between the pregnant women with PROM and the control group (χ² = 4.06, p < 0.05. U. urealyticum was predominant bacterial species found in 62.79% of isolates in the PROM cases, while in 32.56% it was isolated alone. Among the 49 pregnant women with preterm delivery, pPROM occurred in 29 (59.18% examinees, and in 70.83% of pregnant women with findings of high-density U. urealyticum pPROM was observed. Conclusion.

    Objective: To understand the current situations of urine iodine level and iodized salt usage of pregnant women, provide a scientific basis for carrying out iodine nutrition intervention among pregnant women. Methods: Five hundred pregnant women who received antenatal care in the hospital from March to May in 2010 for the first time were selected as study objects, national standard arsenic and cerium catalysis spectrophotometry was used to detect urine iodine, the usage of iodized salt was detected by a questionnaire. Results: The incidences of low iodine, appropriate iodine, and high iodine among the pregnant women were 21.6% , 51.2% , and 27. 2% , respectively. No pregnant women with excessive iodine exceeding human discomfort toleranc was found; the incidence of abnormal iodine level among the rural pregnant women with low educational level was significantly higher than that among the urban pregnant women with high educational level; the correct rate of usage of iodized salt among pregnant women was low. Conclusion: Iodine deficiency and excessive intake of iodine existed in the pregnant women in Hohhot, and the incidences were high.

    Adequate iodine is important during pregnancy to ensure optimal growth and development of the offspring. We validated an iodine-specific FFQ (I-FFQ) for use in Australian pregnant women. A forty-four-item I-FFQ was developed to assess iodine intake from food and was administered to 122 pregnant women at 28 weeks gestation. Iodine supplement use was captured separately at 28 weeks gestation. Correlation between iodine intake from food estimated using the I-FFQ and a 4 d weighed food record as well as correlation between total iodine intake and 24 h urinary iodine excretion (UIE), 24 h urinary iodine concentration (UIC), spot UIC and thyroid function were assessed at 28 weeks gestation. A moderate correlation between the two dietary methods was shown (r 0·349, Pwomen as receiving adequate (≥160 μg/d) or inadequate (women and can be used to screen women who are at risk of inadequate intake.

    Pregnant women have a significantly higher risk of HIV acquisition during gestation than their non-pregnant counterparts due to behavioral and biological factors. Acute seroconversion during gestation results in increased HIV mother-to-child transmission rates and has been identified as a major public health challenge. In order to address potential HIV seroconversion in our pregnant patients, we conducted a prospective cohort study to evaluate the acceptability of offering HIV testing to sexual partners of HIV-negative pregnant women receiving antenatal care at two hospitals in Porto Alegre, Brazil. Over a 14-month study period, HIV-negative pregnant women at two hospital-based clinic sites were encouraged to bring their stable sexual partner for HIV voluntary counseling and testing during prenatal care. Women were re-interviewed following delivery to measure success of the intervention. Of the 1223 HIV-negative pregnant women enrolled in the study, 663 (54%) of their male sexual partners received HIV testing during antenatal care and 4 (0.6%) were diagnosed with HIV infection. A total of 645 women were interviewed at the time of delivery, with 620 (97%) confirming that HIV testing was suggested to their partner. The most common reason provided by women as to why partners did not come for testing was work (69%) and lack of perceived risk (14%). Independent predictors of successful partner testing included being white (odds ratio [OR] 1.59, 95% confidence interval [CI] 1.18-2.12), married (OR 1.78, 95% CI 1.08-2.94), having an older age of sexual debut (OR 0.94, 95% CI 0.9-0.98), and being recruited at Hospital Conceiçao (OR 2.1, 95% CI 1.52-2.88). We conclude that HIV partner testing during prenatal care is acceptable, rendering this intervention attractive to public health programs targeting prevention of sexually transmitted infections.

    Cryogenic probes have significantly increased the sensitivity of NMR. Here, we present a compact EPR receiver design capable of cryogenic operation. Compared to room temperature operation, it reduces the noise by a factor of ≈2.5. We discuss in detail the design and analyze the resulting noise performance. At low microwave power, the input noise density closely follows the emission of a cooled 50Ω resistor over the whole measurement range from 20K up to room temperature. To minimize the influence of the microwave source noise, we use high microwave efficiency (≈1.1-1.7mTW(-1/2)) planar microresonators. Their efficient conversion of microwave power to magnetic field permits EPR measurements with very low power levels, typically ranging from a few μW down to fractions of nW.

    Full Text Available Objective: the aim of this research was to determine the prevalence of Helicobacter pylori infection on Chilean pregnant women and its relationship with the appearance and severity of hyperemesis and dyspepsia. Methods: quantitative study of prevalence in a transversal cut with variable analysis. The sample was taken from 274 Chilean pregnant women from the Bío Bío province through vein puncture between June and December, 2005. Pregnant women were informed of this study, interviewed and signed an informed consent. The samples were processed using ImmunoComb II Helicobacter pylori IgG kit. Statistical analysis was performed by means of the Statistical Package for Social Sciences (SPSS Program. Results: out of the total number of pregnant women, 68.6% showed infection by Helicobacter pylori. 79.6% of the total sample had symptoms of dyspepsia, and 72.5% of this group presented Helicobacter pylori infection. 12.4% showed pregnancy hyperemesis; among them, 79.4% were infected with Helicobacter pylori. 73.4% of the pregnant women that showed gastric discomfort during the first three months had Helicobacter pylori infection. 53.7% of them continued with gastric discomfort after the first three months; of those, 95.8% were infected. Helicobacter pylori infection was present only in 1.5% of pregnant women without gastric discomfort. Conclusion: both, gastric discomfort of pregnant women and the continuity of severe symptoms of dyspepsia and hyperemesis after the first three months of gestation are significantly correlated with Helicobacter pylori infection.

    The aim of the study was to assess the left ventricular (LV) synchronicity in pregnant women and to identify the main determinants of LV dyssynchrony in asymptomatic pregnant women. One hundred sixty-seven pregnant women consecutively and 48 age-matched nonpregnant controls were enrolled. For the assessment of LV systolic dyssynchrony, the standard deviation of the time from QRS onset to peak systolic (Tps-LV- standard deviation [SD]) velocity and the maximal difference of the time from QRS onset to peak systolic velocity (Tps-LV) from 12 segments at the apical views. For the LV diastolic dyssynchrony, the standard deviation of the time from QRS onset to peak diastolic (Tpe-LV-SD) velocity and the maximal difference of the time from QRS onset to peak diastolic velocity (Tpe-LV) were calculated. Both systolic and diastolic dyssynchrony indexes were significantly higher in pregnant women than in the normal controls (Tps-LV; Ppregnant women had a dyssynchrony index above the accepted value for LV dyssynchrony (>34.4 msec). There was a significant correlation between LV dyssynchrony indexes with, multiparty, multifetal pregnancies, systolic blood pressure in pregnant women with LV dyssynchrony. Additionally LV dyssynchrony was significantly associated with elevated E/e" and brain natriuretic peptide (BNP). Both systolic synchronicity and diastolic synchronicity were affected in pregnant women compared to nonpregnant women. LV dyssynchrony was significantly correlated with age, multiparity, and BNP level. Early detectable changes in systolic and diastolic synchrony may be present in pregnant women at higher risk of peripartum cardiomyopathy. © 2017, Wiley Periodicals, Inc.

    Carbon tetrachloride (CCl4) is well known to induce hepatotoxicity after being metabolized to trichloromethyl free radical ((.)CCl3) by CYP2E1. In the present study, the hepatotoxicity induced by a single oral dose (2,000 mg/kg) of CCl4 was compared between pregnant (gestation days (GD) 13 and 19) or postpartum (postpartum days (PPD) 1, 13 and 27) and non-pregnant rats. Hepatotoxicity in CCl4-treated pregnant rats evaluated by blood chemistry (alanine aminotransferase (ALT), aspartate aminotransferase (AST) and lactate dehydrogenase (LDH) activities) and histopathological finding (area of damaged hepatocytes) was minimal on GD19, being weaker than that in non-pregnant rats. CYP2E1 expression in non-treated pregnant rats decreased as pregnancy progressed and reached minimum level on GD19. Thus, the degree of CCl4-induced hepatotoxicity roughly corresponded to CYP2E1 levels during pregnancy. After delivery, hepatotoxicity in CCl4-treated lactating rats was maximal on PPD13, being stronger than that in non-pregnant rats, and then it decreased slightly on PPD27. The CYP2E1 level in the non-treated lactating rats tended to increase but remained at lower levels until PPD13 compared with that in non-pregnant rats. Thus, the degree of CCl4-induced hepatotoxicity did not correspond to CYP2E1 levels during lactation. This suggests that during lactation, there may be certain factors other than CYP2E1 expression responsible for the degree of CCl4-induced hepatotoxicity.

    The purpose of this study is to determine whether the score of the sense of coherence 13-item version (SOC-13) scale in the second trimester of pregnancy is associated with threatened premature birth. All the subjects gave their informed written consent before their participation in the study. A self-reported questionnaire survey was conducted on the pregnant women at approximately 18 weeks of pregnancy. The questionnaire consisted of items on demographic characteristics, perinatal abnormalities, stress perception scale (SPS), and SOC-13 scale. Approximately 30 weeks of pregnancy after the first survey, we surveyed whether any treatment had been provided for threatened premature birth during the course of the current pregnancy. The study period was from December 2007 to February 2010. One hundred and seventy-seven pregnant women participated in the study, but only the data from 151 pregnant women were analyzed. Forty-three (28.5%) pregnant women had threatened premature birth and received some treatment. Logistic regression analysis was carried out with threatened premature birth as the dependent variable and age, childbirth history, smoking habit, history of miscarriage or premature birth in previous pregnancies, SPS score, and SOC-13 scale score as the independent variables. It was shown that SOC-13 scale score affected threatened premature birth (p premature birth. This study suggests that the SOC-13 scale score in the second trimester of pregnancy could be of great value in clinical health care of pregnant women with a risk of threatened premature birth in the subsequent course of pregnancy.

    Administering intravenous antibiotics during labor to women at risk for transmitting Group B Streptococcus (GBS) can prevent infections in newborns. However, the impact of intrapartum antibiotic prophylaxis on mothers' microbial community composition is largely unknown. We compared vaginal microbial composition in pregnant women experiencing preterm birth at ≤ 32 weeks gestation that received intrapartum antibiotic prophylaxis with that in controls. Microbiota in vaginal swabs collected shortly before delivery from GBS positive women that received penicillin intravenously during labor or after premature rupture of membranes was compared to controls. Microbiota was analyzed by 16S rRNA sequencing using the PGM Ion Torrent to determine the effects of penicillin use during hospitalization and GBS status on its composition. Penicillin administration was associated with an altered vaginal microbial community composition characterized by increased microbial diversity. Lactobacillus sp. contributed only 13.1% of the total community in the women that received penicillin compared to 88.1% in the controls. Streptococcus sp. were present in higher abundance in GBS positive woman compared to controls, with 60% of the total vaginal microbiota in severe cases identified as Streptococcus sp. Vaginal communities of healthy pregnant women were dominated by Lactobacillus sp. and contained low diversity, while Group B Streptococcus positive women receiving intrapartum antibiotic prophylaxis had a modified vaginal microbiota composition with low abundance of Lactobacillus but higher microbial diversity.
