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

Full Text Available Objective: Pregnancy brings about significant changes in respiratory function, as evidenced by alterations in lung volumes and capacities, which are attributable to the mechanical impediment caused by the growing foetus. This study was undertaken in order to identify changes in respiratory function during normal pregnancy and to determine whether such changes are more pronounced in twin pregnancy than in singleton pregnancy. Methods: Respiratory function was assessed in 50 women with twin pregnancies and in 50 women with singleton pregnancies (during the third trimester in both groups, as well as in 50 non-pregnant women. We measured the following pulmonary function test parameters: FVC; FEV1; PEF rate; FEV1/FVC ratio; FEF25-75%; and maximal voluntary ventilation. Results: All respiratory parameters except the FEV1/FVC ratio were found to be lower in the pregnant women than in the non-pregnant women. We found no significant differences between women with twin pregnancies and those with singleton pregnancies, in terms of respiratory function. Conclusions: Despite its higher physiological demands, twin pregnancy does not appear to impair respiratory function to any greater degree than does singleton pregnancy.

Among babies born by ART, do singleton survivors of a vanishing twin have lower birth weight than other singletons? Vanishing twin syndrome (VTS) was associated with lower birth weight among ART singletons; a sibship analysis indicated that the association was not confounded by maternal characteristics that remain stable between deliveries. Previous studies indicate that ART singletons with VTS have increased risk of adverse pregnancy outcomes, compared with other ART singletons. The potential contribution of unmeasured maternal background characteristics has been unclear. This was a Norwegian population-based registry study, including 17 368 mothers with 20 410 ART singleton deliveries between January 1984 and December 2013. The study population included 17 291 ART singletons without VTS, 638 ART singletons with VTS and 2418 ART singletons with uncertain vanishing twin status. We estimated differences in birth weight and gestational age comparing ART singletons with VTS first to all ART singletons without VTS, and subsequently to their ART siblings without VTS, using random- and fixed-effects linear regression, respectively. The corresponding comparisons for the associations with preterm birth and small for gestational age (SGA) were conducted using random-and fixed-effects logistic regression. The sibling analysis of preterm birth included 587 discordant siblings, while the sibling analysis of SGA included 674 discordant siblings. ART singletons with VTS had lower birth weight when compared to all ART singletons without VTS, with an adjusted mean difference (95% CI) of -116 g (-165, -67). When we compared ART singletons with VTS to their ART singletons sibling without VTS, the adjusted mean difference was -112 g (-209, -15). ART singletons with VTS also had increased risk of being born SGA, with an adjusted odds ratio (OR) (95% CI) of 1.48 (1.07, 2.03) compared to all ART singletons without VTS, and 2.79 (1.12, 6.91) in the sibship analyses.

To enlist the complications with nuchal cord in singleton term pregnancies and to determine maternal and fetal outcome in singleton term pregnancies. Design: Descriptive study. Place and duration of study: The study was carried out at Gynaecology and Obstetric department Combined Military Hospital Quetta from Nov 2007 to May 2008. Patients and methods: One hundred women irrespective of parity with healthy, singleton term pregnancy and cephalic presentation, labouring or not labouring, were selected from outpatient department. A total of 41 patients were booked with Doppler ultrasound done in antenatal period. Other 59 were poorly booked and diagnosed with cord around neck by clinical criteria e.g. high head at term, fetal distress, meconium discharge, slow progress in labour leading to prolonged labour. All patients signed well informed written proforma regarding study and its outcome. Vigilant feto maternal monitoring was done during labour. All events during labour were mentioned in proformas which were attached with patients case notes. Data was interperated in term of frequency and percentages. Results: Complications with cord around neck found were still birth 3%, fetal distress 15%, intrauterine death 1%. Prolonged labour was seen in 14%, Meconium discharge in 5%, and high presenting part was found in 11% of cases. Maternal outcome were elective caesarean section in 6%, emergency caesarean-section in 32%, spontaneous vaginal delivery in 54% and instrumental vaginal delivery in 8% of the cases. Different fetal outcomes seen were intrauterine death, stillbirth in 1%, and 3% patients respectively. Regarding neonatal outcome, 31% stayed in neonatal intensive care unit (NICU) for less than 48 hours, 69% stayed in NICU for more than 48 hours out of which 4% had early neonatal deaths (ENND). Fifty nine percent patients detected and suspected during labour were with, high head, slow progress in labour, decreased fetal movements, intra partum fetal distress, meconium

Twin pregnancy is associated with more pregnancy complications and poorer pregnancy outcome than singleton pregnancy. Hence periodic review is necessary to improve on the pregnancy outcome. To determine the incidence and compare pregnancy complications and obstetric outcomes of twin pregnancies and singleton pregnancies. The twin pregnancies (study group) that were delivered at Nnamdi Azikiwe University Teaching Hospital (NAUTH), Nnewi, South-East Nigeria from 1st February 2005 to 31st January 2010 were compared with singleton deliveries (control group) that occurred in the same hospital during the same period. A total of 3351 deliveries were conducted during the study period, of which 113 were twin deliveries, giving an incidence of 1:29.6 deliveries. Only 100 case files could be retrieved for analysis. The mean parities for the twins and singletons were 2.7 ± 2.33 weeks and 1.96 ± 1.87 weeks whereas the mean gestational age at delivery for twin and singleton deliveries were 34 ± 5.2 weeks and 38.7 ± 2.4 weeks respectively (P < 0.05). The mean birth weights were 3.14 ± 0.73 kg and 2.3 ± 1.0 kg for singletons and twins respectively (P < 0.05). Hypertensive disorders of pregnancy, cord prolapse, malpresentation, premature rupture of membranes, low Apgar scores, cesarean section rate, and perinatal death were significantly higher in twin pregnancies than in singleton. The incidence of twin pregnancy over the study period was high and was significantly associated with more pregnancy complications and poorer obstetric outcomes. Close antenatal and intrapartum care are needed in order to improve outcome and decrease complications.

Cervical cerclage is a well-known surgical procedure carried out during pregnancy. It involves positioning of a suture (stitch) around the neck of the womb (cervix), aiming to give mechanical support to the cervix and thereby reduce risk of preterm birth. The effectiveness and safety of this procedure remains controversial. This is an update of a review last published in 2012. To assess whether the use of cervical stitch in singleton pregnancy at high risk of pregnancy loss based on woman's history and/or ultrasound finding of 'short cervix' and/or physical exam improves subsequent obstetric care and fetal outcome. We searched Cochrane Pregnancy and Childbirth's Trials Register (30 June 2016) and reference lists of identified studies. We included all randomised trials of cervical suturing in singleton pregnancies. Cervical stitch was carried out when the pregnancy was considered to be of sufficiently high risk due to a woman's history, a finding of short cervix on ultrasound or other indication determined by physical exam. We included any study that compared cerclage with either no treatment or any alternative intervention. We planned to include cluster-randomised studies but not cross-over trials. We excluded quasi-randomised studies. We included studies reported in abstract form only. Three review authors independently assessed trials for inclusion. Two review authors independently assessed risk of bias and extracted data. We resolved discrepancies by discussion. Data were checked for accuracy. The quality of the evidence was assessed using the GRADE approach. This updated review includes a total of 15 trials (3490 women); three trials were added for this update (152 women). Cerclage versus no cerclageOverall, cerclage probably leads to a reduced risk of perinatal death when compared with no cerclage, although the confidence interval (CI) crosses the line of no effect (RR 0.82, 95% CI 0.65 to 1.04; 10 studies, 2927 women; moderate quality evidence).

To assess the impact of glycemic control in gestational on neonatal weight and metabolic complications of twin and singleton pregnancies. An observational, retrospective study to monitor 120 twin and 240 singleton pregnancies in women with GDM. Maternal glycemic parameters during pregnancy (oral glucose tolerance test results, treatment, insulinization rate, mean HbA1c in the third trimester), and neonatal complications and weight were recorded. A higher infant birth weight ratio (IBWR 1.02±0.12 vs. 0.88±0.12, P<.001) and a lower rate of newborns small for gestational age (severe SGA 2.5% vs. 8.3%, P=.012) were seen after singleton pregnancies as compared to twin pregnancies. The rates of newborns large for gestational age (LGA 12.6% vs. 12.5%, P=.989); macrosomic (6.7% vs. 7.5%, P=.777); or small for gestational age (SGA 6.7% vs. 10.8%, P=.175) were similar in both groups. Neonates from twin pregnancies had a higher risk of hypoglycemia (adjusted OR 4.71; 1.38-16.07, P=.013) and polycythemia (adjusted OR 10.05; 1.82-55.42, P=0.008). A linear relationship was seen between third trimester HbA1c levels and IBWR in singleton (r=.199, P=.003), but not in twin pregnancies (r=0.049, P=0.610). Risk of severe SGA, hypoglycemia, and polycythemia was significantly higher in twin pregnancies of women with GDM. Neonatal weight outcomes and metabolic complications in twin pregnancies of women with GDM were not related to glycemic control. Moreover, in our study population, fasting glucose at diagnosis and mean HbA1c in the third trimester showed a linear relationship with higher birth weights in singleton, but not in twin pregnancies.

The ovarian hyperstimulation syndrome is the combination of increased ovarian volume, due to the presence of multiple cysts and vascular hyperpermeability, with subsequent hypovolemia and hemoconcentration. We report a case of spontaneous syndrome in a singleton pregnancy. This was a spontaneous pregnancy with 12 weeks of gestational age. The pregnancy was uneventful until 11 weeks of gestational age. After that, the pregnant woman complained of progressive abdominal distention associated with abdominal discomfort. She did not report other symptoms. In the first trimester, a routine ultrasonography showed enlarged ovaries, multiples cysts and ascites. Upon admission, the patient was hemodynamically stable, her serum β-hCG was 24,487mIU/mL, thyroid-stimulating hormone was 2.2µUI/mL and free T4 was 1.8ng/dL. All results were within normal parameters. However, levels of estradiol were high (10,562pg/mL). During hospitalization, she received albumin, furosemide and prophylactic dose of enoxaparin. The patient was discharged on the sixth hospital day. RESUMO A síndrome de hiperestimulação ovariana é a combinação do aumento dos ovários, devido à presença de múltiplos cistos e de hiperpermeabilidade vascular, com subsequente hipovolemia e hemoconcentração. Relata-se um caso de síndrome espontânea em uma gestação única. Trata-se de gravidez espontânea com 12 semanas de idade gestacional. A gravidez ocorreu sem intercorrências até 11 semanas de idade gestacional. Após, a gestante passou a se queixar de distensão abdominal progressiva, associada com desconforto abdominal. A paciente não relatava outros sintomas. A ultrassonografia de rotina no primeiro trimestre mostrou ovários aumentados com múltiplos cistos e ascite. No momento da internação, a paciente apresentava-se hemodinamicamente estável, com β-hCG sérico de 24.487mUI/mL, hormônio estimulante da tireoide de 2,2µUI/m e T4 livre de 1,8ng/dL, ou seja, valores dentro dos par

To determine the difference in costs between singleton and twin pregnancies after IVF treatment from pregnancy to 6 weeks after delivery from a health care perspective. Retrospective cost analysis. IVF department at the University Medical Center Nijmegen, The Netherlands. A representative sample of singleton and twin pregnancies after IVF treatment between 1995 and 2001 at the University Medical Center Nijmegen. IVF with or without intracytoplasmic sperm injection and with or without cryopreservation. Medical costs per singleton and twin pregnancy after IVF. In patients pregnant with twins, the incidence of hospital antenatal care, complicated vaginal deliveries, and cesarean sections was higher and was associated with more frequent and longer maternal and neonatal hospital admissions. Maternal and neonatal hospital admissions were the major cost drivers. The medical cost per twin pregnancy was found to be more than five times higher than per singleton pregnancy, 13,469 and 2,550, respectively. The medical cost per twin pregnancy was more than 10,000 higher than per singleton pregnancy. A reduction in the number of twin pregnancies by elective single ET will save substantial amounts of money. This money might be used for the additional IVF cycles that will probably be needed to achieve similar success rates between single ET and two-embryo transfer.

To develop a Canadian consensus document on maternal screening for fetal aneuploidy (e.g., Down syndrome and trisomy 18) in singleton pregnancies. Pregnancy screening for fetal aneuploidy started in the mid 1960s, using maternal age as the screening test. New developments in maternal serum and ultrasound screening have made it possible to offer all pregnant patients a non-invasive screening test to assess their risk of having a fetus with aneuploidy to determine whether invasive prenatal diagnostic testing is necessary. This document reviews the options available for non-invasive screening and makes recommendations for Canadian patients and health care workers. To offer non-invasive screening for fetal aneuploidy (trisomy 13, 18, 21) to all pregnant women. Invasive prenatal diagnosis would be offered to women who screen above a set risk cut-off level on non-invasive screening or to pregnant women whose personal, obstetrical, or family history places them at increased risk. Currently available non-invasive screening options include maternal age combined with one of the following: (1) first trimester screening (nuchal translucency, maternal age, and maternal serum biochemical markers), (2) second trimester serum screening (maternal age and maternal serum biochemical markers), or (3) 2-step integrated screening, which includes first and second trimester serum screening with or without nuchal translucency (integrated prenatal screen, serum integrated prenatal screening, contingent, and sequential). These options are reviewed, and recommendations are made. Studies published between 1982 and 2009 were retrieved through searches of PubMed or Medline and CINAHL and the Cochrane Library, using appropriate controlled vocabulary and key words (aneuploidy, Down syndrome, trisomy, prenatal screening, genetic health risk, genetic health surveillance, prenatal diagnosis). Results were restricted to systematic reviews, randomized controlled trials, and relevant observational

To study maternal and perinatal outcomes after physical examination-indicated cerclage in both singleton and twin pregnancies and evaluate the possible risk factors associated. Retrospective review of all women undergoing physical examination-indicated cerclage at the Hospital Vall d'Hebro, Barcelona from January 2009 to December 2012 after being diagnosed with cervical incompetence and risk of premature birth. During the study period, 60 cases of women diagnosed with cervical incompetence who were carrying live and morphologically-normal fetuses (53 singleton and 7 twin pregnancies), and who had an imminent risk of premature birth were evaluated. Mean gestational age until birth was 35 weeks in singleton and 32 weeks in twin pregnancies. Four cases (7.5%) of immature births and one case (2.0%) of neonatal death were recorded in singleton pregnancies. No cases of immature births or neonatal deaths were recorded in twin pregnancies. Diagnostic amniocentesis was performed IN all cases to rule out possible chorioamnionitis. Physical examination-indicated cerclage for cervical incompetence in women at risk for immature or preterm birth demonstrates good perinatal prognosis without increasing maternal morbidity in either singleton or twin pregnancies. The increase in gestation time in our study may also have been due to the fact that patients with subclinical chorioamnionitis were excluded by diagnostic amniocentesis.

Singleton pregnancy after assisted reproductive technology (ART) has been associated with higher risks of adverse pregnancy outcome than naturally conceived singleton pregnancy. This study was to elucidate whether the ART procedure is responsible for abnormal pregnancy outcome comparing those after ART and non-ART in infertile patients. We compare the singleton pregnancy outcome of infertile patients in our university hospital between 2000 and 2008 following ART (351 pregnancies) and non-ART (213 pregnancies) procedures. Pregnancy outcome parameters were incidence of pregnancy induced hypertension, placenta previa, placental abruption, cesarean delivery, preterm birth, very preterm birth, stillbirth, low birth weight and very low birth weight. Most of the pregnancy outcome parameters were not significantly different between the ART group and the non-ART group. Only placenta previa was significantly higher in the ART group than in the non-ART group (odds ratio 4.0; 95 % CI 1.2-13.7). ART procedure may itself be a risk factor for the development of placenta previa. Some of the abnormal perinatal outcomes that had been previously attributed to ART, however, may be due to the baseline characteristics of infertile patients.

Several studies have reported increasing trends in preterm birth in developed countries, mainly attributable to an increase in medically indicated preterm births. Our aim was to describe trends in preterm birth among singleton and multiple pregnancies in the Netherlands. Prospective cohort study. Nationwide study. We studied 1,451,246 pregnant women from 2000 to 2007. We assessed trends in preterm birth. We subdivided preterm birth into spontaneous preterm birth after premature prelabour rupture of membranes (pPROM), medically indicated preterm birth and spontaneous preterm birth without pPROM. We performed analyses separately for singletons and multiples. The primary outcome was preterm birth, defined as birth before 37 weeks of gestation, with very preterm birth (birth was 7.7% and the risk of very preterm birth was 1.3%. In singleton pregnancies, the preterm birth risk decreased significantly from 6.4% to 6.0% (P birth without pPROM (3.6-3.1%, P birth risk increased significantly (47.3-47.7%, P = 0.047), mainly as a result of medically indicated preterm birth, which increased from 15.0% to 17.9% (P birth risk in singleton pregnancies decreased significantly over the years. The trend of increasing preterm birth risk reported in other countries was only observed in (medically indicated) preterm birth in multiple pregnancies. © 2011 The Authors BJOG An International Journal of Obstetrics and Gynaecology © 2011 RCOG.

The association between infection and inflammatory response in singleton preterm birth (PTB) is well established, yet, less is known about PTB in twins. We aimed to compare the placental component and pregnancy outcome in pregnancies complicated with PTB of singletons vs. twin deliveries. We hypothesized that due to different underlying mechanisms, placental inflammatory lesions will be more prevalent in placentas derived from singleton pregnancies than twins. Labor characteristics, neonatal outcome and placental histopathology reports of spontaneous PTB at 24-33 6 / 7 weeks, from 1/2008-12/2015, were reviewed. were compared between dichorionic-diamniotic twin deliveries (twins group) and singleton deliveries (singleton group) matched for gestational age. Excluded from the study medically indicated deliveries, due to preeclampsia or fetal growth restriction, and monochorionic twins. Placental lesions were classified to maternal vascular supply lesions, fetal vascular supply lesions, and maternal (MIR) and fetal (FIR) inflammatory responses. Composite neonatal outcome was defined as one or more of early complications: respiratory distress, necrotizing enterocolitis, sepsis, blood transfusion, ventilation, seizures, intra-ventricular hemorrhage, hypoglycemia, phototherapy, or death. The twins group (n=72) was characterized by higher maternal BMI (p=0.009), and higher rates of assisted reproductive techniques (56.2% vs. 17.8%, pPTBs are characterized by higher rate of inflammatory and malperfusion lesions. The lack of these findings in twins PTBs suggests different factors that participate in the development of preterm birth in twins, such as over-distension of the uterus and up regulation of oxytocin receptors.

Information about the recurrence of spontaneous preterm birth in subsequent twin/singleton pregnancies is scattered. To quantify the risk of recurrence of spontaneous preterm birth in different subtypes of subsequent pregnancies. An electronic literature search in OVID MEDLINE and EMBASE, complemented by PubMed, to find recent studies. Studies comparing the risk of spontaneous preterm birth after a previous preterm and previous term pregnancy. The absolute risk of recurrence with a 95% confidence interval and the absolute risk of preterm birth after a term delivery were calculated. Data from studies were pooled using the Mantel-Haenszel method. We detected 13 relevant studies. The risk of recurrence of preterm birth was significantly increased in all preterm pregnancy subtypes, compared with their term counterparts. Women pregnant with twins after a previous preterm singleton had the highest absolute risk of recurrence (57.0%, 95% CI 51.9-61.9%), and after a previous term singleton their absolute risk was 25% (95% CI 24.3-26.5%). Women pregnant with a singleton after a previous preterm twin pregnancy have an absolute recurrence risk of 10% (95% CI 8.2-12.3%), whereas a singleton pregnancy after delivering a previous twin up to term yields a low absolute risk of only 1.3% (95% CI 0.8-2.2). Women pregnant with a singleton after a previous preterm singleton have an absolute recurrence risk of 20% (95% CI 19.9-20.6). The risk of recurrence of preterm birth is influenced by the singleton/twin order in both pregnancies, and varies between 10% for a singleton after previous preterm twins to 57% for twins after a previous preterm singleton. © 2014 Royal College of Obstetricians and Gynaecologists.

To evaluate perinatal outcomes in singleton and twin pregnancies with pathologically confirmed velamentous cord insertion without vasa previa. This retrospective case-control study included all nonanomalous singleton and twin pregnancies with pathologically confirmed velamentous cord insertion delivered in a single institution between January 1, 2005, and July 1, 2015, and having an ultrasound examination by maternal-fetal medicine. For each case, the next 2 consecutive deliveries matched for gestational age at delivery ± 1 week and, in twins, amnionicity and chorionicity served as controls. Primary outcomes included surgical delivery for a nonreassuring intrapartum fetal heart rate tracing, umbilical arterial cord pH of less than 7.2, 5-minute Apgar score of less than 7, birth weight below the 10th percentile, neonatal intensive care unit admission, fetal or neonatal death, and cord avulsion necessitating manual placental extraction. Outcomes were available for 53 singletons with 103 matched controls and 33 twin pregnancies with 65 matched controls. In singletons, velamentous cord insertion was associated with cord pH of less than 7.2 (odds ratio [OR] 3.5; 95% confidence interval [CI], 1.1-11.2; P = .039), 5-minute Apgar score of less than 7 (OR, 5.3; 95% CI, 0.99-28.1; P = .045), and cord avulsion requiring manual placental extraction (7.5% versus 0%; P = .012). Associations were suggested with increased surgical delivery for a nonreassuring intrapartum fetal heart rate tracing (OR, 2.4; 95% CI, 0.9-6.9; P = .14), birth weight below the 10th percentile (OR, 2.1; 95% CI, 0.8-5.9; P = .21), and fetal or neonatal death (3.8% versus 0%; P = .11). Velamentous cord insertions were also associated with placental abruption in singletons (7.5% versus 0%; P = .013). Among twins, velamentous cord insertion was associated with fetal or neonatal death (9.1% versus 0%; P = .036). Isolated confirmed velamentous cord insertion is associated

Full Text Available Background/Aim. Preterm birth is the leading cause of neonatal mortality. Periventricular hemorrhage-intraventricular hemorrhage (PVH-IVH remains a significant cause of both morbidity and mortality in infants prematurely born. The aim of the study was to evaluate the perinatal outcome regarding IVH of premature babies according to the mode of delivery. Methods. A total of 126 women in preterm singleton pregnancies with vertex presentation and 126 neonates weighted from 750 g to 1,500 g at birth were enrolled. The outcomes of 64 neonates born vaginally were compared to 62 neonates born by cesarean section. Results. There was no significant difference in the incidence of IVH among both groups. Conclusion. Our data is consistent with the hypothesis that the mode of delivery does not influence IVH and consenquently perinatal outcome in preterm neonates.

To evaluate whether home cervical ripening is safe and results in shorter hospital stay. This was a retrospective cohort study of women with singleton pregnancies having induction of labor for postmaturity at a single center between January 2007 and June 2010. Women were offered home cervical ripening with 1 mg dinoprostone gel if they were nulliparous, had uncomplicated singleton pregnancies, and the indication for induction was postmaturity. Nine hundred seven of 1,536 (59.1%) nulliparous women having induction of labor for postmaturity were eligible for home cervical ripening. The median number of hours at home was 11.76 hours (range 0-24.82 hours). There were no cases of birth outside of the hospital, uterine rupture, or significant neonatal morbidity or neonatal death related to home cervical ripening. Eighty-five (5.5%) women who underwent hospital cervical ripening because of maternal preference or social issues formed a hospital cervical ripening comparison group. There was no significant difference in the total number of hours before delivery spent in the hospital between the two groups (26.25; 95% confidence interval [CI] 25.27-27.23 in home cervical ripening group compared with 24.28; 95% CI 22.5-26.0 in the hospital group; P=.26). Clinical outcomes are comparable in nulliparous women who receive a single dose of dinoprostone gel for home cervical ripening compared with those who undergo hospital cervical ripening. However, preadmission home cervical ripening with 1 mg dinoprostone does not decrease the number of hours women spend in the hospital. II.

Doppler sonography of the uterine artery (UA) is done to monitor pregnancies, because the detected flow patterns are useful to draw inferences about possible disorders of trophoblast invasion. Increased resistance in the UA is associated with an increased risk of preeclampsia and/or intrauterine growth restriction (IUGR) and perinatal mortality. In the absence of standardized figures, the normal ranges of the various available reference curves sometimes differ quite substantially from one another. The causes for this are differences in the flow patterns of the UA depending on the position of the pulsed Doppler gates as well as branching of the UA. Because of the discrepancies between the different reference curves and the practical problems this poses for guideline recommendations, we thought it would be useful to create our own reference curves for Doppler measurements of the UA obtained from a singleton cohort under standardized conditions. This retrospective cohort study was carried out in the Department of Obstetrics of the Charité - Universitätsmedizin Berlin, the Department for Obstetrics and Prenatal Medicine of the University Hospital Halle (Saale) and the Center for Prenatal Diagnostics and Human Genetics Kurfürstendamm 199. Available datasets from the three study locations were identified and reference curves were generated using the LMS method. Measured values were correlated with age of gestation, and a cubic model and Box-Cox power transformation (L), the median (M) and the coefficient of variation (S) were used to smooth the curves. 103 720 Doppler examinations of the UA carried out in singleton pregnancies from the 11th week of gestation (10 + 1 GW) were analyzed. The mean pulsatility index (Mean PI) showed a continuous decline over the course of pregnancy, dropping to a plateau of around 0.84 between the 23rd and 27th GW, after which it decreased again. Age of gestation, placental position, position of pulsed Doppler gates and branching of

To compare outcomes for women undergoing two in vitro fertilization (IVF) pregnancies with singletons and women undergoing one IVF twin pregnancy. The concept of single-embryo transfer in IVF has reduced the risks of both maternal and neonatal complications, but there is still a discussion of whether or not twins are a desired outcome of IVF. Registry study. Not applicable. All reported twins after IVF with double-embryo transfer (n = 1,982) and their mothers (n = 991) and all mothers (n = 921) who gave birth to two IVF singletons (n = 1,842). None. Maternal and neonatal outcomes including severe neonatal morbidity. Preterm birth, very preterm birth, low birth weight, very low birth weight, and small for gestational age were dramatically increased for IVF twins compared with two IVF singletons with the same mother, with adjusted odds ratios from 4 to 16. Significantly higher rates of respiratory complications, sepsis, and jaundice were detected among the IVF twins. Significantly higher rates of preeclampsia, preterm premature rupture of the membranes, and cesarean section were observed for IVF twin pregnancies. The neonatal and maternal outcomes were dramatically better for women undergoing two IVF singleton pregnancies compared with one IVF twin pregnancy after double-embryo transfer. These results support single-embryo transfer to minimize the risks associated with twin pregnancies. Copyright © 2013 American Society for Reproductive Medicine. Published by Elsevier Inc.

Does mode of conception [spontaneous/after infertility treatment (IT)], type of pregnancy (singleton/twin) and parent gender have an effect on anxiety and depression levels and trajectories during pregnancy and the post-partum period? Conception after IT was associated with a transitory increase in anxiety during the perinatal period for parents of singletons, while for IT parents of twins higher levels of psychopathological symptoms tended to persist during pregnancy and the post-partum period. Most previous studies have shown that successful IT is not associated with poor psychological well-being during pregnancy and the post-partum period, but there is also some evidence for heightened pregnancy-related anxiety, lower self-esteem and lower self-efficacy. Parents of twins experience increased postnatal anxiety and depression. This prospective longitudinal study assessed 267 couples (N = 534) at each trimester of pregnancy, after childbirth and at 3 months post-partum. The sample comprised 36 couples who had conceived after IT (19 twin pairs and 17 singletons) and 231 couples who had conceived spontaneously (SC; 28 twin pairs and 203 singletons). Couples were recruited at four public hospitals in Portugal, and self-report measures of anxiety and depression symptoms were administered. IT parents reported higher anxiety after childbirth than parents who SC, regardless of pregnancy type. IT parents of twins showed higher anxiety at mid-pregnancy, as well as higher anxiety and depression at 3 months post-partum than IT parents of singletons. Among IT mothers, those who had twins exhibited higher depression after childbirth than those who had singletons. Differences according to mode of conception, pregnancy type and parents gender over time were also noted. During pregnancy, IT parents of twins showed no significant change in depression scores, while the other groups depression scores statistically significantly decreased over time.

Objective: To compare the difference in risks of obstetric complications of singleton pregnancy between women with hyperandrogenic polycystic ovary syndrome (PCOS) and women with normoandrogenic PCOS. Methods: Prospective cohort study. This study was a secondary analysis of data collected during a multicenter randomized controlled clinical trial. Women who got clinical singleton pregnancy were grouped according to whether they were diagnosed with hyperandrogenism at baseline. There were 118 women with hyperandrogenism and 366 women without hyperandrogenism. The incidences of obstetric complications and birth weight were compared between the two groups. Results: Women with hyperandrogenic PCOS had a significantly higher risk of preterm delivery than women with normoandrogenic PCOS [12.7% (15/118) versus 3.6% (13/366); OR= 3.94, 95% CI: 1.82-8.56]. After adjustment of age, duration of infertility, body mass index, and fresh or frozen embryo transfer group, hyperandrogenism was still associated with an increased risk of preterm delivery ( OR= 3.67, 95% CI: 1.67-8.07). Compared with women with normoandrogenic PCOS, women with hyperandrogenic PCOS had similar risks of pregnancy loss, gestational diabetes mellitus, pre-eclampsia, placenta previa, and postpartum hemorrhage (all P> 0.05). Birth weight as well as the risks of being small for gestational age and large for gestational age were also comparable between the two groups (all P> 0.05). Conclusion: In women with PCOS and singleton pregnancy, those with preconceptional hyperandrogenism have a higher risk of preterm delivery than those without hyperandrogenism.

The purpose of this study was to establish reference charts of fetal biometric parameters measured by 2-dimensional sonography in a large Brazilian population. A cross-sectional retrospective study was conducted including 31,476 low-risk singleton pregnancies between 18 and 38 weeks' gestation. The following fetal parameters were measured: biparietal diameter, head circumference, abdominal circumference, femur length, and estimated fetal weight. To assess the correlation between the fetal biometric parameters and gestational age, polynomial regression models were created, with adjustments made by the determination coefficient (R(2)). The means ± SDs of the biparietal diameter, head circumference, abdominal circumference, femur length, and estimated fetal weight measurements at 18 and 38 weeks were 4.2 ± 2.34 and 9.1 ± 4.0 cm, 15.3 ± 7.56 and 32.3 ± 11.75 cm, 13.3 ± 10.42 and 33.4 ± 20.06 cm, 2.8 ± 2.17 and 7.2 ± 3.58 cm, and 256.34 ± 34.03 and 3169.55 ± 416.93 g, respectively. Strong correlations were observed between all fetal biometric parameters and gestational age, best represented by second-degree equations, with R(2) values of 0.95, 0.96, 0.95, 0.95, and 0.95 for biparietal diameter, head circumference, abdominal circumference, femur length, and estimated fetal weight. Fetal biometric parameters were determined for a large Brazilian population, and they may serve as reference values in cases with a high risk of intrauterine growth disorders. © 2014 by the American Institute of Ultrasound in Medicine.

The prevalence of asymptomatic bacteriuria (ASB) in pregnancy is 2-10% and is associated with both maternal and neonatal adverse outcomes as pyelonephritis and preterm delivery. Antibiotic treatment is reported to decrease these adverse outcomes although the existing evidence is of poor quality. We plan a combined screen and treat study in women with a singleton pregnancy. We will screen women between 16 and 22 weeks of gestation for ASB using the urine dipslide technique. The dipslide is considered positive when colony concentration ≥105 colony forming units (CFU)/mL of a single microorganism or two different colonies but one ≥105 CFU/mL is found, or when Group B Streptococcus bacteriuria is found in any colony concentration. Women with a positive dipslide will be randomly allocated to receive nitrofurantoin or placebo 100 mg twice a day for 5 consecutive days (double blind). Primary outcomes of this trial are maternal pyelonephritis and/or preterm delivery before 34 weeks. Secondary outcomes are neonatal and maternal morbidity, neonatal weight, time to delivery, preterm delivery rate before 32 and 37 weeks, days of admission in neonatal intensive care unit, maternal admission days and costs. This trial will provide evidence for the benefit and cost-effectiveness of dipslide screening for ASB among low risk women at 16-22 weeks of pregnancy and subsequent nitrofurantoin treatment. Dutch trial registry: NTR-3068.

Observational studies have reported varying results about the association of velamentous cord insertion (VCI) with adverse pregnancy outcomes. To evaluate the risk of preterm delivery among singleton pregnancies complicated by VCI. Various databases were searched for English-language articles published up to February, 28, 2017, using keywords including VCI; abnormal placentation; abnormal cord insertions; adverse perinatal outcomes; and preterm birth. Outcome measures included preterm delivery; pre-eclampsia; cesarean delivery; fetal demise in utero (FDIU); and small for gestational age (SGA). Only studies involving VCI were included in the meta-analysis. Analyses were performed using RevMan version 5.3.5 (The Nordic Cochrane Centre, Copenhagen, Denmark). There were six studies included in the analysis. The VCI and control groups comprised 16 295 and 1 366 485 women, respectively. An increased incidence of preterm delivery was found for the VCI group compared with the control group (11.8% vs 7.0%; adjusted odds ratio [aOR] 1.95, 95% confidence interval [CI] 1.85-2.04). A diagnosis of VCI was also associated with cesarean delivery (aOR 1.17, 95% CI 1.12-1.23), SGA (aOR 1.93, 95% CI 1.83-2.04), and FDIU (aOR 3.96, 95% CI 3.21-4.89). The presence of VCI was associated with adverse pregnancy outcomes. © 2018 International Federation of Gynecology and Obstetrics.

Abstract Introduction: Maternal smoking during pregnancy has been associated with an increased risk for psychiatric morbidity. We further studied this with Finnish siblings to control for genetic/familial factors. Methods: From the Finnish Medical Birth Register, sibling pairs were selected as the first two children born 1987–1995 to the same mother (n = 150 168 pairs), along with information on maternal smoking (no smoking/smoking). Information on the children’s psychiatric diagnoses related to outpatient care visits (1998–2013) and inpatient care (1987–2013), and the mothers’ psychiatric morbidity (1969–2013) was derived from the Finnish Hospital Discharge Register. The first pair analysis compared siblings of mothers who only smoked in the first pregnancy (Quitters, 4.7%) and mothers who smoked in both pregnancies (Smokers, 9.6%); the second analysis included mothers who smoked only in the second pregnancy (Starters, 3.3%) and mothers who did not smoke in either pregnancy (Nonsmokers, 77.5%). Smoking information was missing for 5.0% of pairs. Psychiatric morbidity of the siblings and mother was included in the statistical analyses. Results: The risk of psychiatric diagnoses was significantly lower for the second child of quitters (adjusted OR 0.77, 95% CI 0.72–0.83) compared to the risk among smokers. A higher risk for psychiatric diagnoses was found for the second child of starters (1.39, 1.30–1.49) compared to the risk among nonsmokers. The effect of smoking was more robust for externalizing diagnoses. Conclusions: Maternal smoking was independently associated with a higher risk for psychiatric morbidity in children, even when controlling thoroughly for genetic and familial factors. Implications: Maternal smoking during pregnancy has an independent effect on the risk of psychiatric morbidity in children, even after controlling for non-measurable genetic/familial factors by using a sibling pair design. The effect of maternal smoking was robust
Full Text Available Uterine anomalies involving a double uterus, double cervix, also known as didelphys uterus, and complete septate vagina are rarely seen and have an associated fertility problem. However, artificial reproductive technology with embryo transfers can help solve this fertility challenge. Conception in the uterus in just one side is commonly seen for embryos, which are always transferred through the usually used (dilated vagina. We here present a patient with the above uterine anomaly who conceived with the aid of in vitro fertilization and embryo transfer to both uterine cavities under general anesthesia, which resulted in successful double singleton pregnancies with one fetus in each uterus. With intensive prenatal care, the pregnancy course for each fetus was rather uneventful. Although both fetuses were in cephalic presentation, cesarean section was performed at the 39th week of gestation with good outcomes in order to preclude anticipated difficulties if the baby had been delivered through the rarely dilated vagina. However, order of birth between the two fetuses was a crucial decision during the operation.
Full Text Available The aim of the study was to compare the single pregnancy and neonate outcome after fresh and frozen-thawed embryo transfer in the in vitro fertilization programme (IVF. The study focused on clinical and laboratory factors affecting the abnormal placentation, especially placenta praevia, in patients conceiving in the IVF programme. The results confirm that neonates born after frozen-thawed embryo transfer had significantly higher mean birth weight than after fresh embryo transfer (ET. Moreover, the birth weight distribution in singletons was found to shift towards “large for gestation” (LGA after frozen-thawed ET. On the other hand, the pregnancies after fresh ET were characterized by a higher incidence of placenta praevia and 3rd trimester bleeding. Placenta praevia was more common in IVF patients with fresh ET in a stimulated cycle than in patients with ET in a spontaneous cycle. It occurred more frequently in patients with transfer of 2 embryos. From this point of view, single ET and ET in a spontaneous cycle should be encouraged in good prognosis patients in the future with more than two good quality embryos developed. An important issue arose of how the ovarian hormonal stimulation relates to abnormal placentation and if the serum hormone levels interfere with in the IVF treatment results.

To evaluate benefits and harms of food intake during labor. Electronic databases such as MEDLINE and ClinicalTrials.gov were searched from their inception until October 2016. We included randomized trials comparing a policy of less-restrictive food intake with a policy of more restrictive food intake during labor. The primary outcome was the mean duration of labor. Meta-analysis was performed using the random-effects model of DerSimonian and Laird to produce summary treatment effects in terms of either a relative risk or a mean difference with 95% confidence interval (CI). Ten trials, including 3,982 laboring women, were included. All the studies involved laboring singletons considered at low risk because they had no obstetric or medical complications that would increase the likelihood of cesarean delivery. In three studies, women were allowed to select from a low-residue diet throughout the course of labor. One study had honey date syrup as the allowed food intake. Five studies had carbohydrate drinks as food intake in labor. The last one was the only trial that allowed unrestrictive food intake. In the included studies, all women in the intervention group were allowed the assigned food intake until delivery, whereas women in a control group were allowed only ice chips, water, or sips of water until delivery. A policy of less-restrictive food intake was associated with a significantly shorter duration of labor (mean difference -16 minutes, 95% CI -25 to -7). No other benefits or harms in obstetric or neonatal outcome were noticed. Regurgitation during general anesthesia and Mendelson syndrome did not occur in either group. Women with low-risk singleton pregnancies who were allowed to eat more freely during labor had a shorter duration of labor. A policy of less-restrictive food intake during labor did not influence other obstetric or neonatal outcomes nor did it increase the incidence of vomiting. Operative delivery rates were similar.

To evaluate perinatal outcomes in women sent home with a diagnosis of false labor at term and assess the time interval to return for delivery. This was a prospective observational cohort study of women at 37 0/7 to 41 6/7 weeks of gestation without pre-existing medical complications who presented to our hospital-based triage unit with symptoms of labor and underwent a standardized evaluation. Women diagnosed as having false labor with a live singleton fetus in cephalic presentation without a prior cesarean delivery and sent home were compared with a group of similar women diagnosed to be in spontaneous labor. Women with hypertension, diabetes, and known fetal malformations were excluded. Using a perinatal composite outcome of respiratory insufficiency, intraventricular hemorrhage, culture-proven sepsis, Apgar score 3 or less at 5 minutes, phototherapy, and perinatal death, we tested the noninferiority of being sent home compared with being admitted for labor. The relationship of cervical dilatation to the time interval from discharge home to delivery was also analyzed. Between October 2012 and March 2016, a total of 3,949 women met inclusion criteria and were diagnosed with false labor, discharged, and returned to deliver, whereas 2,592 similar women were admitted in early labor. The mean interval from discharge to return was 4.9 days. Cesarean delivery rates were not different between the study groups-11% for both (P=.69), and the perinatal composite outcome rates were not significantly different between those sent home and those admitted-3.2% compared with 3.1% (P=.79). Women with more advanced cervical dilatation at discharge returned and delivered significantly earlier than those with less dilatation regardless of parity. Discharge with false labor at term after a standardized assessment in a triage unit was not associated with increased rates of adverse perinatal composite outcomes or cesarean delivery. The time interval to return for delivery was

Hyperreactio luteinalis is an unusual condition in which, during pregnancy, both ovaries are enlarged by multiple theca lutein cysts that produce a high level of testosterone. Several weeks postpartum, the cysts resolve and testosterone level returns to normal. Two case studies are presented in which mothers with gestational ovarian theca lutein cysts experienced delayed lactogenesis II. The elevated testosterone at the time of birth suppressed milk production. Once the testosterone level dropped to approximately 300 ng/dL, milk production began. After the initial delay, both mothers breastfed their infants without supplementation.

We know little about the relationship between the macroeconomy and birth outcomes, in part due to the methodological challenge of distinguishing effects of economic conditions on fetal health from effects of economic conditions on selection into live birth. We examined associations between state-level unemployment rates in the first 2 trimesters of pregnancy and adverse birth outcomes, using natality data on singleton live births in the United States during 1990-2013. We used fixed-effect logistic regression models and accounted for selection by adjusting for state-level unemployment before conception and maternal characteristics associated with both selection and birth outcomes. We also tested whether associations between macroeconomic conditions and birth outcomes differed during and after (compared with before) the Great Recession (2007-2009). Each 1-percentage-point increase in the first-trimester unemployment rate was associated with a 5% increase in odds of preterm birth, while second-trimester unemployment was associated with a 3% decrease in preterm birth odds. During the Great Recession, however, first-trimester unemployment was associated with a 16% increase in odds of preterm birth. These findings increase our understanding of the effects of the Great Recession on health and add to growing literature suggesting that macro-level social and economic factors contribute to perinatal health. © The Author(s) 2017.

To study the success rate, predictors for success, and pregnancy outcomes after external cephalic version. Historical cohort study. Regional hospital, Hong Kong. All women who had singleton term breech pregnancies at term and opted for external cephalic version during 2001 and 2009. Their demographic data, clinical and ultrasound findings, procedure details, complications, and delivery outcomes were analysed. Predictive factors for successful external cephalic version. A total of 209 external cephalic versions were performed during the 9-year period. The success rate was 63% (75% for multiparous and 53% for nulliparous women). There was no significant complication. On univariate analysis, predictors of successful external cephalic version were: multiparity, unengaged presenting part, higher amniotic fluid index (≥ 10 cm), thin abdominal wall, low uterine tone, and easily palpable fetal head (subjective assessment by practitioners before external cephalic version). On multivariate analysis, only multiparity, non-engagement of the fetal buttock and thin maternal abdomen were associated with successful external cephalic version. In all, 69% of those who had successful external cephalic version succeeded in the first roll (Pexternal cephalic versions had vaginal deliveries (93% in multiparous and 69% in nulliparous women). Uptake rate of external cephalic version was studied in the latter part of the study period (2006-2009). Whilst 735 women were eligible for external cephalic version, 131 women chose to have the procedure resulting in an uptake rate of 18%. External cephalic version was effective in reducing breech presentations at term and corresponding caesarean section rates, but the uptake rate was low. Further work should address the barriers to the low acceptance of external cephalic version. The results of this study could encourage women to opt for external cephalic version.

A woman's behaviors during pregnancy can have a significant influence on her baby's healthy development. Women who smoke or drink alcohol during pregnancy, go without prenatal care or suffer from poor nutrition are more likely to experience complications during pregnancy or childbirth, and their babies are at increased risk for developing a number…

Pregnancy-induced hypertension (PIH) has been associated with a decreased risk of infant mortality in small for gestational age (SGA) preterm infants. To evaluate the influence of PIH on mortality and major neonatal morbidities in singleton preterm SGA infants, in the presence and absence of acute pregnancy complications. Population-based observational study of singleton SGA infants, born at 24 to 32 weeks gestation in the period 1995-2010 (n = 2139). Multivariable logistic regression analyses were used to assess the independent effect of PIH on mortality and neonatal morbidities. Acute pregnancy complications comprised premature labor, premature rupture of membranes >6 h, antepartum hemorrhage and clinical chorioamnionitis. In the absence of pregnancy complications, the odds ratio (95% confidence interval) for mortality (0.77; 0.50-1.16), survival without severe neurological morbidity (1.14; 0.79-1.65) and survival without bronchopulmonary dysplasia (BPD) (0.85; 0.59-1.21) were similar in the PIH versus no-PIH groups. In the presence of pregnancy complications, mortality (0.76; 0.40-1.44), survival without severe neurological morbidity (1.16; 0.64-2.12) and survival without BPD (1.04; 0.58-1.86) were also similar in the PIH versus no-PIH groups. PIH was not associated with improved outcome in preterm SGA infants, both in the presence and absence of acute pregnancy complications.

To determine whether gestational diabetes mellitus (GDM) is an independent risk factor for postpartum urinary incontinence in singleton pregnancies. A longitudinal cohort study. A single tertiary-care hospital in Taiwan. Pregnant women with term deliveries between 2002 and 2007 (n = 6653) were consecutively recruited. Logistic regression models were fitted based on generalised estimating equation methods to derive odds ratios for occurrences of type-specific urinary incontinence in the third trimester and at four time-points over 2 years during the postpartum period. Evaluation of whether GDM is an independent risk factor for postpartum urinary incontinence. The full model analysis revealed that GDM was an independent risk factor for all type-specific urinary incontinence (odds ratio [95% confidence interval]: 1.97 [1.56-2.51], 3.11 [2.18-4.43] and 2.73 [1.70-4.40] for stress, urge and mixed incontinence, respectively]. Compared with women without GDM, women with GDM tended to exhibit more severe symptoms of stress incontinence for up to 2 years postpartum, whereas for urge or mixed incontinence, more severe symptoms were found only for 6 months postpartum. Evaluation of quality of life using the Incontinence Impact Questionnaire 7 suggested that women with GDM requiring insulin treatment had a higher likelihood of functional impairment than women with GDM requiring conservative treatment only or women without GDM (P risk factor for postpartum urinary incontinence and had a significant impact on quality of life. Women with GDM should be provided with timely consultation and support once urinary incontinence occurs. © 2012 The Authors BJOG An International Journal of Obstetrics and Gynaecology © 2012 RCOG.

The group theoretical structure underlying physics in anti de Sitter (AdS) spacetime is intrinsically different with respect to the flat case, due to the presence of special ultra-short representations, named singletons, that do not admit a flat space limit. The purpose of this collaboration is to exploit this feature in the study of string and brane dynamics in AdS spacetime, in particular while trying to establish a connection between String Theory in AdS backgrounds (in the tensionless limit) and Higher-Spin Gauge Theory.

To determine fetal growth in low risk pregnancies at the beginning of the third trimester and to assess the relative importance of fetal gender and maternal parity. Dutch primary care midwifery practice. Retrospective cohort study on 3641 singleton pregnancies seen at a primary care midwifery center in the Netherlands. Parameters used for analysis were fetal abdominal circumference (AC), fetal head circumference (HC), gestational age, fetal gender and maternal parity. Regression analysis was applied to describe variation in AC and HC with gestational age. Means and standard deviations in the present population were compared with commonly used reference charts. Multiple regression analysis was applied to examine whether gender and parity should be taken into account. The fetal AC and HC increased significantly between the 27th and the 33rd week of pregnancy (AC r2=0.3652, Pgender was a significant determinant for both AC (PParity contributed significantly to AC only but the difference was small (beta=0.00464). At the beginning of the third trimester, fetal size is associated with fetal gender and, to a lesser extent, with parity. Some fetal growth charts (e.g., Chitty et al.) are more suitable for the low-risk population in the Netherlands than others.

To investigate whether assisted reproductive technology (ART) increases the risk of fetal chromosomal abnormalities. A total of 2034 singleton pregnant women were included in this retrospective study. They were divided into ART (574 fetuses) and control groups (1460 fetuses conceived naturally). All pregnant women received screening according to the Fetal Medicine Foundation, London 2004 Kypros H. Nicolaides guidelines at 11-13+6 weeks of gestation. Accordingly, women with value at risk of chromosomal abnormalities >1:250 underwent chorionic villus sampling or amniocentesis. Mean body mass index was 22.83 ± 3.27 versus 21.29 ± 2.81 kg/m(2) in the ART and control groups, respectively (P fetal chromosomal abnormalities. Additionally, fetus size in the ART group was bigger than that in the natural conception group. © 2015 Japan Society of Obstetrics and Gynecology.

The objective of this study was to evaluate the underlying causes of neonatal mortality (NNM) in midwife-attended home births and compare them to hospital births attended by a midwife or a physician in the United States (US). A retrospective cohort study of the Centers for Disease Control (CDC) linked birth/infant death data set (linked files) for 2008 through 2012 of singleton, term (≥37 weeks) births and normal newborn weights (≥2500 grams). Midwife-attended home births had the highest rate of neonatal deaths [122/95,657 neonatal mortality (NNM) 12.75/10,000; relative risk (RR): 3.6, 95% confidence interval (CI) 3-4.4], followed by hospital physician births (8695/14,447,355 NNM 6.02/10,000; RR: 1.7 95% CI 1.6-1.9) and hospital midwife births (480/1,363,199 NNM 3.52/10,000 RR: 1). Among midwife-assisted home births, underlying causes attributed to labor and delivery caused 39.3% (48/122) of neonatal deaths (RR: 13.4; 95% CI 9-19.9) followed by 29.5% due to congenital anomalies (RR: 2.5; 95% CI 1.8-3.6), and 12.3% due to infections (RR: 4.5; 95% CI 2.5-8.1). There are significantly increased risks of neonatal deaths among midwife-attended home births associated with three underlying causes: labor and delivery issues, infections, and fetal malformations. This analysis of the causes of neonatal death in planned home birth shows that it is consistently riskier for newborns to deliver at home than at the hospital. Physicians, midwives, and other health care providers have a professional responsibility to share information about the clinical benefits and risks of clinical management.

Full Text Available There is limited evidence to support the use of customised centile charts to identify those at risk of stillbirth and infant death at term. We sought to determine birth weight thresholds at which mortality and morbidity increased and the predictive ability of noncustomised (accounting for gestational age and sex and partially customised centiles (additionally accounting for maternal height and parity to identify fetuses at risk.This is a population-based linkage study of 979,912 term singleton pregnancies in Scotland, United Kingdom, between 1992 and 2010. The main exposures were noncustomised and partially customised birth weight centiles. The primary outcomes were infant death, stillbirth, overall mortality (infant and stillbirth, Apgar score <7 at 5 min, and admission to the neonatal unit. Optimal thresholds that predicted outcomes for both non- and partially customised birth weight centiles were calculated. Prediction of mortality between non- and partially customised birth weight centiles was compared using area under the receiver operator characteristic curve (AUROC and net reclassification index (NRI.Birth weight ≤25th centile was associated with higher risk for all mortality and morbidity outcomes. For stillbirth, low Apgar score, and neonatal unit admission, risk also increased from the 85th centile. Similar patterns and magnitude of associations were observed for both non- and partially customised birth weight centiles. Partially customised birth weight centiles did not improve the discrimination of mortality (AUROC 0.61 [95%CI 0.60, 0.62] compared with noncustomised birth weight centiles (AUROC 0.62 [95%CI 0.60, 0.63] and slightly underperformed in reclassifying pregnancies to different risk categories for both fatal and non-fatal adverse outcomes (NRI -0.027 [95% CI -0.039, -0.016], p < 0.001.

Full Text Available Healthy behaviors in pregnant women have a major effect on pregnancy outcomes; however, only few studies have explored the relationship of multiple psychosocial factors with healthy lifestyles during pregnancy. The objective of this study was to investigate whether the five psychosocial factors of anxiety, stress, depression, marital dissatisfaction, and social support are associated with six domains of healthy lifestyles in pregnant women, including nutrition, physical activity, health responsibility, stress management, interpersonal relationships, and self-actualization. In this cross-sectional study, 445 pregnant women from the obstetrics clinics of the teaching hospitals of Babol University of Medical Sciences were included. The subjects answered six questionnaires, including the Health-Promoting Lifestyle Profile, Beck Depression Inventory, Prenatal Distress Questionnaire, State-Trait Anxiety Inventory, Social Support Questionnaire, and Marital Satisfaction Scale. We developed a series of simple linear regression models based on each subscale of lifestyle (nutrition, physical activity, health responsibility, stress management, interpersonal relationships, and self-actualization as the dependent variables and the five psychological variables (anxiety, stress, depression, marital dissatisfaction, and social support as the independent variables. State and trait anxieties were the strongest negative predictors of all aspects of a healthy lifestyle. Furthermore, depression was negatively associated with all of the six subscales of a healthy lifestyle. Pregnancy-specific stress was the only negative predictor of stress management and self-actualization.

Are there differences in preconception cardiovascular function between women who have a viable pregnancy and those who have a first trimester miscarriage? Preconception cardiovascular function of central haemodynamics and arterial function are similar between women who have a viable pregnancy and those who have a first trimester miscarriage. Miscarriages have been associated with increased long-term cardiovascular disease risk, and arterial and cardiovascular dysfunction has been hypothesised as the common link. It is not known if these risks are present prior to pregnancy or are a reflection of poor arterial and haemodynamic adaptation to pregnancy. This prospective longitudinal preconception cohort study was conducted over 18 months. In total, 367 participants were recruited pre-pregnancy, from which 197 pregnancies were recorded; 39 of these pregnancies ended in first trimester miscarriage. Complete longitudinal data were available for 172 pregnancies (140 viable pregnancies, 32 first trimester miscarriages) from pre-pregnancy to 6 weeks gestation. This was a single site study based at a maternity hospital in London. Healthy women were recruited prior to natural conception and followed up once they became pregnant. All underwent haemodynamic [cardiac output (CO), peripheral vascular resistance (PVR)] and arterial function [aortic augmentation index (AIx) and pulse wave velocity (PWV)] testing prior to pregnancy and at 6 weeks gestation, using non-invasive devices (gas re-breathing method, Innocor® and an occilometric device, Vicorder®). Cross-sectional measurements at pre-pregnancy and 6 weeks gestation and a longitudinal analysis of changes were compared between women who had a subsequent viable pregnancy, and those who had a subsequent first trimester miscarriage. There were no differences between women destined to have a healthy ongoing pregnancy compared to those who miscarried, in terms of baseline cardiovascular function, assessed by CO, PVR, PWV or AIx

Full Text Available ABSTRACT Purpose: To investigate subfoveal choroidal thickness (SFCT in patients with pre-eclampsia using enhanced depth imaging optical coherence tomography (EDI-OCT. Methods: A sample of 73 pregnant women was studied over 28 weeks of gestation. The sample was divided into two groups: one comprising pre-eclamptic pregnant women (n=32, and the other comprising healthy pregnant women (n=41. The SFCT was determined for all patients using EDI-OCT during pregnancy and at the third month of the postpartum period. Results: The SFCTs in pre-eclamptic pregnant women were 351.97 ± 22.44 and 332.28 ± 20.32 µm during the pregnancy and postpartum periods (p<0.001, respectively, whereas these values in healthy pregnant women were 389.73 ± 49.64 and 329.78 ± 22.36 µm (p<0.001, respectively. During pregnancy SFCT in pre-eclamptic pregnant women was significantly thinner than that in healthy pregnant women (p<0.001. However, there was no statistically significant difference during the postpartum period (p=0.623. Conclusions: The results suggest that SFCT is significantly decreased in pre-eclamptic pregnant women than in healthy pregnant women, despite no statistically significant difference in SFCT existing between the groups during the postpartum period.

The use of nevirapine in HIV-infected pregnant women is discouraged due to its potential to cause hepatotoxicity. There is limited information available on the toxicity in non-HIV infected newborn exposed to this drug during pregnancy. The aim of the study is to determine the extent of hepatotoxicity in the newborn exposed to nevirapine and HIV during pregnancy. A cross-sectional, observational, multicenter study was conducted on a cohort of healthy infants born to HIV-infected mothers, in whom the first determination of alanine aminotransferase (ALT), before 6weeks of age, was collected. Patients were allocated to 2groups according to exposure to nevirapine during pregnancy. Hepatotoxicity was rated according to the AIDS Table for Grading the Severity of Adult and Pediatric Adverse Events (DAIDS). This study included 160newborns from 159pregnancies (88exposed to nevirapine-based regimens and 71 exposed to protease inhibitors-based therapies). No cases of hepatotoxicity were observed according to the DAIDS Table for Grading. Two cases of ALT above normal values (2.8%; 95%CI: 0.3-9.8%) were observed in patients not exposed to nevirapine, and one case (1.1%; 95%CI: 0.0-6.1%) in the group exposed to nevirapine (P=.585). The lack of differences between groups suggests that highly active antiretroviral treatment regimens including nevirapine administered during pregnancy do not involve a higher risk of liver disease compared to other treatment combinations.

Watchful waiting or induction of labour--a matter of informed choice: identification, analysis and critical appraisal of decision aids and patient information regarding care options for women with uncomplicated singleton late and post term pregnancies: a review.
Berger, Bettina; Schwarz, Christiane; Heusser, Peter
Decision-making during pregnancy regarding different options of care can be difficult, particularly when risks of intervention versus no intervention for mother and baby are unclear. Unbiased information and support for decision making may be beneficial in these situations. The management of normal pregnancies at and beyond term is an example of such a situation. In order to determine the need to develop an evidence-based decision aid this paper searches, analyses and appraises patient decision aids and patient information leaflets regarding care options in cases of late term and post-term pregnancies, including complementary and alternative medicine (CAM). A literature search was carried out in a variety of lay and medical databases. written information related to uncomplicated singleton pregnancies and targeted at lay people. Analysis and appraisal of included material by means of quality criteria was set up based on the International Patient Decision Aid Standards accounting for evidence-basing of CAM options. Inclusion of two decision aids and eleven leaflets from four decision aids and sixteen leaflets. One decision aid met the quality criteria almost completely, the other one only insufficiently despite providing some helpful information. Only one leaflet is of good quality, but cannot substitute a decision aid. There is an urgent need for the design of an evidence-based decision aid of good quality for late-term or post-term pregnancy, particularly in German language.

To analyse the factors associated with the level of adherence to a Mediterranean dietary pattern in healthy Spanish women before pregnancy. A prospective series of 1175 women. An FFQ validated in Spanish populations served to collect dietary data. The Mediterranean Diet Adherence Index was used to assess the level of adherence to a Mediterranean diet pattern. Polytomic regression was performed to identify the associated factors. Catchment area of Virgen de las Nieves University Hospital, Andalusia, Spain. The women were invited to participate in the study at the 20th-22nd gestational week. The selection criteria were: Spanish nationality, 18 years of age or older, singleton pregnancy and absence of health problems that required modifying the diet or physical activity. An inverse relationship was found between women's age and level of adherence to a Mediterranean diet pattern, with a clear dose-response association: a younger age entailed worse adherence (P smoking and sedentary lifestyle had a positive relationship with low adherence, giving OR = 5·36 (95 % 1·91, 15·07) for women who smoked >20 cigarettes/d and OR = 2·07 (95 % CI 1·34, 3·17) for sedentary women. Higher age, higher educational level, and higher social class of the women were associated with a higher level of adherence to the Mediterranean diet (P smoking and lack of exercise were associated with low adherence to a Mediterranean diet.
Singletons exist, as particles and as local fields, only in 3+2 de Sitter space. Their kinematical properties make them natural candidates for constituents of massless fields, and perhaps for quarks. It is interesting to find out how to describe this type of compositeness in flat space. A theory of interacting singleton fields in de Sitter space is now available, and in this paper we study the flat-space limit of the Green's functions of that theory. The flat-space limit is an autonomous theory of Green's functions, but is not an operator field theory. The three-point function is calculated and its flat-space limit is found to reveal glimpses of a physical interpretation. Causal and spectral properties are in accord with the tenets of axiomatic field theory. The theory is a generalization of local field theory, in which photons appear as composite objects although the physical S matrix is the same as in conventional QED

Full Text Available Pregnancy induces drastic biological changes systemically, and has a beneficial effect on some autoimmune conditions such as rheumatoid arthritis (RA. However, specific systemic changes that occur as a result of pregnancy have not been thoroughly examined in healthy women or women with RA. The goal of this study was to identify genes with expression patterns associated with pregnancy, compared to pre-pregnancy as baseline and determine whether those associations are modified by presence of RA.In our RNA sequencing (RNA-seq dataset from 5 healthy women and 20 women with RA, normalized expression levels of 4,710 genes were significantly associated with pregnancy status (pre-pregnancy, first, second and third trimesters over time, irrespective of presence of RA (False Discovery Rate (FDR-adjusted p value<0.05. These genes were enriched in pathways spanning multiple systems, as would be expected during pregnancy. A subset of these genes (n = 256 showed greater than two-fold change in expression during pregnancy compared to baseline levels, with distinct temporal trends through pregnancy. Another 98 genes involved in various biological processes including immune regulation exhibited expression patterns that were differentially associated with pregnancy in the presence or absence of RA.Our findings support the hypothesis that the maternal immune system plays an active role during pregnancy, and also provide insight into other systemic changes that occur in the maternal transcriptome during pregnancy compared to the pre-pregnancy state. Only a small proportion of genes modulated by pregnancy were influenced by presence of RA in our data.
Full Text Available Changes in maternal innate immunity during healthy human pregnancy are not well understood. Whether basal immune status in vivo is largely unaffected by pregnancy, is constitutively biased towards an inflammatory phenotype (transiently enhancing host defense or exhibits anti-inflammatory bias (reducing potential responsiveness to the fetus is unclear. Here, in a longitudinal study of healthy women who gave birth to healthy infants following uncomplicated pregnancies within the Canadian Healthy Infant Longitudinal Development (CHILD cohort, we test the hypothesis that a progressively altered bias in resting innate immune status develops. Women were examined during pregnancy and again, one and/or three years postpartum. Most pro-inflammatory cytokine expression, including CCL2, CXCL10, IL-18 and TNFα, was reduced in vivo during pregnancy (20-57%, p<0.0001. Anti-inflammatory biomarkers (sTNF-RI, sTNF-RII, and IL-1Ra were elevated by ~50-100% (p<0.0001. Systemic IL-10 levels were unaltered during vs. post-pregnancy. Kinetic studies demonstrate that while decreased pro-inflammatory biomarker expression (CCL2, CXCL10, IL-18, and TNFα was constant, anti-inflammatory expression increased progressively with increasing gestational age (p<0.0001. We conclude that healthy resting maternal immune status is characterized by an increasingly pronounced bias towards a systemic anti-inflammatory innate phenotype during the last two trimesters of pregnancy. This is resolved by one year postpartum in the absence of repeat pregnancy. The findings provide enhanced understanding of immunological changes that occur in vivo during healthy human pregnancy.

Cervical length screening by transvaginal sonography (TVS) has been shown to be a good predictive test for spontaneous preterm birth (PTB) in symptomatic singleton pregnancy with threatened preterm labor (PTL). The aim of this review and meta-analysis of individual participant data was to evaluate the effect of knowledge of the TVS cervical length (CL) in preventing PTB in singleton pregnancies presenting with threatened PTL. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register and the Cochrane Complementary Medicine Field's Trials Register (May 2016) and reference lists of retrieved studies. Selection criteria included randomized controlled trials of singleton gestations with threatened PTL randomized to management based mainly on CL screening (intervention group), or CL screening with no knowledge of results or no CL screening (control group). Participants included women with singleton gestations at 23 + 0 to 36 + 6 weeks with threatened PTL. We contacted corresponding authors of included trials to request access to the data and perform a meta-analysis of individual participant data. Data provided by the investigators were merged into a master database constructed specifically for the review. The primary outcome was PTB DE PARTO PREMATURO: REVISIÓN SISTEMÁTICA Y METAANÁLISIS DE ENSAYOS CONTROLADOS ALEATORIZADOS HACIENDO USO DE LOS DATOS INDIVIDUALES DE LAS PACIENTES: RESUMEN OBJETIVO: El cribado mediante la longitud cervical obtenida con ecografía transvaginal (ETV) ha demostrado ser una buena prueba para la predicción del parto pretérmino espontáneo (PPTE) en embarazos con feto único sintomáticos debido a la amenaza de parto pretérmino (PPT).

Rodent models suggest that some folate-resistant NTDs can be prevented by inositol (myoinositol and chiroinositol supplementation prior to pregnancy. Should folic acid be combined with myoinositol periconceptional supplementation to reduce the overall risk of NTDs even in humans? Hereafter, we discuss the results from the PONTI study that strongly support both the effectiveness and safety of myoinositol periconceptional supplementation in preventing human NTDs. We further report on the largest case series of pregnancies treated with myoinositol and folic acid. At our institution, a sequential study during 12 years involved mothers at risk of fetal NTDs, and 29 babies from 27 pregnancies were born after periconceptional combined myoinositol and folic acid supplementation. No case of NTDs was observed, despite the high recurrence risk in the mothers. Taken together, those data suggest that periconceptional folic acid plus myoinositol can reduce both the occurrence and recurrence risks of NTDs in a greater number of cases than folic acid alone.

Previous studies have found associations between individual healthy behaviors and reduced risk of gestational diabetes mellitus (GDM); however, the association of composite healthy lifestyle during pregnancy with GDM has not been examined. Participants in the Omega Study (n = 3,005), a pregnancy cohort study conducted in Washington State (1996-2008), reported information on diet, physical activity, smoking, and stress during early pregnancy. Lifestyle components were dichotomized into healthy/unhealthy and then combined into a total lifestyle score (range, 0-4). Regression models were used to determine relative risk of GDM (n = 140 cases) in relation to healthy lifestyle. Twenty percent of participants had a healthy diet, 66% were physically active, 95% were nonsmokers, and 55% had low stress. Each 1-point increase in lifestyle score was associated with a 21% lower risk of GDM (95% confidence interval: 0.65, 0.96) after adjustment for age, race, and nulliparity. Adjustment for prepregnancy body mass index, prepregnancy physical activity, and prepregnancy smoking attenuated the associations slightly. Associations were similar in normal-weight and overweight/obese women. In this study, a composite measure of healthy lifestyle during early pregnancy was associated with substantially lower GDM risk. Public health messaging and interventions promoting multiple aspects of a healthy lifestyle during early pregnancy should be considered for GDM prevention. © The Author(s) 2017.

Full Text Available Background: Worldwide there is a high prevalence of 25-hydroxyvitamin D (25OHD deficiency and has been associated with adverse outcomes during pregnancy. Objective: This is a nested, case–control study in a longitudinal cohort to compare the serum 25OHD levels and other biomarkers throughout pregnancy in a group of 20 preeclamptic women and 61 healthy pregnant women. An additional group of 29 healthy non-pregnant women were also studied during the two phases of the menstrual cycle. Results: Mean 25OHD levels in non-pregnant women were 31.9 ng/mL and 34.9 ng/mL during follicular and luteal phase, respectively (P < 0.01. Mean serum 25OHD levels in healthy pregnant women were 26.5, 30.1 and 31.9 ng/mL, at first, second and third trimester, respectively (P < 0.001. The first trimester levels of 25OHD were lower than those of healthy non-pregnant women (P < 0.001, showing a significant recovery at third trimester. In the group of healthy pregnant women, the 25OHD levels were 25.7 ng/mL and 27.2 ng/mL at 3 and 6 months postpartum, respectively; both values were lower than those observed in the non-pregnant women (P < 0.001. In preeclamptic women, 25OHD serum levels were similar to those of healthy pregnant women; nevertheless, they remained almost unchanged throughout pregnancy. Conclusion: There were no significant differences between healthy and preeclamptic pregnant women in terms of 25OHD levels throughout the pregnancy. Serum 25OHD levels in non-pregnant women were higher during luteal phase compared with follicular phase. The 25OHD levels of non-pregnant women tended to be higher than those of pregnant women.

To examine the impact of pre-pregnancy obesity on adverse outcomes in twin compared to singleton pregnancies. Dichorionic twin gestations with maternal body mass index >30 were matched to three singleton controls. Both obese groups were matched (1:3) with non-obese controls. Rates of preeclampsia, gestational diabetes, cesarean section, and preterm birth were compared. One hundred eighty-nine dichorionic twin pregnancies in obese mothers were matched to 567 twin pregnancies in non-obese mothers, and to 567 singleton pregnancies in obese mothers. The latter were matched to 1701 non-obese mothers with singletons. Preeclampsia was more common in obese mothers with both twins and singletons (odds ratio (OR) 3.95, 95% confidence interval (CI) 2.18-7.16 and OR 6.53, 95% CI 3.75-11.4, respectively) as was gestational diabetes (OR 4.35, 95% CI 2.18-8.69; OR 5.53 95% CI 3.60-8.50). Obese mothers with singletons were more likely to deliver abdominally, but the cesarean rates were obesity independent in twins. Obese mothers were more likely to deliver at Obesity-attributable adverse outcomes are lower in twins compared to singletons. Obesity increases the risk of preterm birth regardless of plurality.

Full Text Available Background: Multiple pregnancies occur more frequently in assisted reproductive technology (ART compared to normal conception (NC. It is known that the risk of congenital malformations in a multiple pregnancy are higher than single pregnancy. The aim of this study is to compare congenital malformations in singleton infants conceived by ART to singleton infants conceived naturally. Materials and Methods: In this historical cohort study, we performed a historical cohort study of major congenital malformations (MCM in 820 singleton births from January 2012 to December 2014. The data for this analysis were derived from Tehran’s ART linked data file. The risk of congenital malformations was compared in 164 ART infants and 656 NC infants. We performed multiple logistic regression analyses for the independent association of ART on each outcome. Results: We found 40 infants with MCM 29 (4.4% NC infants and 14 (8.3% ART infants. In comparison with NC infants, ART infants had a significant 2-fold increased risk of MCM (P=0.046. After adjusting individually for maternal age, infant gender, prior stillbirth, mother’s history of spontaneous abortion, and type of delivery, we did not find any difference in risk. In this study the majority (95.1% of all infants were normal but 4.9% of infants had at least one MCM. We found a difference in risk of MCMs between in vitro fertilization (IVF and intracytoplasmic sperm injection (ICSI. We excluded the possible role of genotype and other unknown factors in causing more malformations in ART infants. Conclusion: This study reported a higher risk of MCMs in ART singleton infants than in NC singleton infants. Congenital heart disease, developmental dysplasia of the hip (DDH, and urogenital malformations were the most reported major malformations in singleton ART infants according to organ and system classification.

In 2004, Human Reproduction published a debate series focusing on the rising tide of multiple pregnancy associated with IVF. The premise of the primary report in that debate was that by considering IVF outcomes differently-by focusing on healthy singleton birth at term rather than clinical pregnancy, the standard currency at that time-the necessary shift toward reduced numbers of embryos transferred might be accelerated. The choice of end-point in that debate-Birth Emphasizing a Successful Singleton at Term (BESST)-was not an effort to 'dumb down' the complex equation linking risks and benefits. That balance is a dynamic and various mix of issues that clinicians discuss with patients on a daily basis. And BESST was certainly not proposed as a new primary outcome for application to other treatment modalities in reproductive medicine, such as ovulation induction. It was simply a responsible and brave call for change in the accelerating and competitive world of IVF. © The Author 2015.

Full Text Available The aim of the present study was to evaluate the levels of pro-insulin and pro-insulin/ insulin ratio (PIR in pregnant with normal glucose tolerance (NGT, pregnant with gestational diabetes mellitus (GDM and women after delivery with GDM history. Normal pregnancy is characterized by progressive insulin resistance, which is physiologically compensated by an increase in insulin secretion. The higher secretion of the insulin precursor pro-insulin has been associated with β-cell dysfunction. A total of 102 pregnant women between 24-28 gestational weeks (53 GDM pregnant, 49 with NGT and 22 postpartum with GDM history, as assessed by a 2h oral glucose tolerance test, were included in the study. Fasting plasma insulin and pro-insulin (PI concentrations at the basal state were measured in all women. The ratio pro-insulin/insulin was calculated. BMI was significantly higher in GDM pregnant compared to NGT weight-matched group (30.56 ± 6.9 vs. 30.56 ± 6.9; p < 0, 011 and compared to the levels after delivery (30.56 ± 6.9vs. 27.9 ± 6, 27; p < 0, 001. Significant differences in the levels of PI between NGT and GDM pregnant (3.94 ± 2.78 vs. 7.59 ± 5.27; p = 0.006, between GDM and postpartum women (7.59 ± 5.27 vs. 4.46 ± 1.14; p = 0.022 were established. No signifi cant difference in the level of PIR between two pregnant groups was observed.

Full Text Available Maternal nutrition during pregnancy and lactation influences the growth and potential development of the fetus and contributes to the maturity of a healthy baby.The lack of sufficient calories, of macro- and micronutrients, can lead to deficiencies in building materials for the development and growth of the fetus: moreover there is growing evidence that the maternal nutritional status can alter the epigenetic state of the fetal genome, therefore alterations in nutrition during crucial periods of fetal development may result in developmental adaptations that permanently change the physiology, the metabolism of the offspring, and, as a consequence, predispose these individuals to diseases as adults.In this review we collected indications for the recommended intake of calories and nutrients for a healthy diet during pregnancy and lactation, also analyzing some nutritional choices that may increase the risk of nutritional deficiencies and the way to prevent them.Pregnancy-related dietary changes should begin prior to conception, with appropriate modifications throughout pregnancy and lactation, and appropriate supplementation of vitamins and minerals.

Infant birth weight has increased in Ireland in recent years along with levels of childhood overweight and obesity. The present article reviews the current literature on maternal glycaemia and the role of the dietary glycaemic index (GI) and its impact on pregnancy outcomes. It is known that maternal weight and weight gain significantly influence infant birth weight. Fetal macrosomia (birth weight >4000 g) is associated with an increased risk of perinatal trauma to both mother and infant. Furthermore, macrosomic infants have greater risk of being obese in childhood, adolescence and adulthood compared to normal-sized infants. There is evidence that there is a direct relationship between maternal blood glucose levels during pregnancy and fetal growth and size at birth, even when maternal blood glucose levels are within their normal range. Thus, maintaining blood glucose concentrations within normal parameters during pregnancy may reduce the incidence of fetal macrosomia. Maternal diet, and particularly its carbohydrate (CHO) type and content, influences maternal blood glucose concentrations. However, different CHO foods produce different glycaemic responses. The GI was conceived by Jenkins in 1981 as a method for assessing the glycaemic responses of different CHO. Data from clinical studies in healthy pregnant women have documented that consuming a low-GI diet during pregnancy reduces peaks in postprandial glucose levels and normalises infant birth weight. Pregnancy is a physiological condition where the GI may be of particular relevance as glucose is the primary fuel for fetal growth.
Full Text Available Abdominal pregnancy is a rare form of ectopic pregnancy with very high morbidity and mortality for both the mother and the fetus. Diagnosis and management can pose some difficulties especially in low resource centres. High index of suspicious is vital in making prompt diagnosis in such situations. A young lady of 30 years presented with 2nd gravida at 31 wks pregnancy with pain in the whole abdomen having loose motion admitted in Dept of Obs and Gynae BSMMU. She was diagnosed as a case of 31 wks pregnancy with gastroenteritis. She was treated conservatively according to advice of gastroenterologist and was discharged after improvement. Patient was readmitted again with pervaginal watery discharge. Decision for cesarean section was taken because of transverse lie, fetal growth restriction with severe oligohydramnios. After opening the abdomen, abdominal pregnancy was diagnosed. Following delivery of the baby significant bleeding started which was secured with ligature. Placenta was kept in situ. Mother and baby were discharged healthy on fourteenth postoperative day.

Poor maternal diet in pregnancy can influence fetal growth and development. We tested the hypothesis that poor maternal diet quality during pregnancy would increase neonatal adiposity (percent fat mass (%FM)) at birth by increasing the fat mass (FM) component of neonatal body composition. Our analysis was conducted using a prebirth observational cohort of 1079 mother-offspring pairs. Pregnancy diet was assessed via repeated Automated Self-Administered 24-h dietary recalls, from which Healthy Eating Index-2010 (HEI-2010) scores were calculated for each mother. HEI-2010 was dichotomized into scores of ⩽57 and >57, with low scores representing poorer diet quality. Neonatal %FM was assessed within 72 h after birth with air displacement plethysmography. Using univariate and multivariate linear models, we analyzed the relationship between maternal diet quality and neonatal %FM, FM, and fat-free mass (FFM) while adjusting for prepregnancy body mass index (BMI), physical activity, maternal age, smoking, energy intake, preeclampsia, hypertension, infant sex and gestational age. Total HEI-2010 score ranged between 18.2 and 89.5 (mean: 54.2, s.d.: 13.6). An HEI-2010 score of ⩽57 was significantly associated with higher neonatal %FM (β=0.58, 95% confidence interval (CI) 0.07-1.1, Pdiet quality during pregnancy increases neonatal adiposity independent of maternal prepregnancy BMI and total caloric intake. This further implicates maternal diet as a potentially important exposure for fetal adiposity.

The aim of this study was to determine the maternal serum endoglin concentration in pregnancies with intrauterine growth restriction (IUGR) in the presence or absence of preeclampsia and to compare the results with preeclamptic pregnant women with appropriate-for-gestational-age weight infants and with healthy pregnant controls. The study was performed on 52 normotensive pregnant patients with pregnancy complicated by isolated IUGR, 33 patients with preeclampsia complicated by IUGR and 33 preeclamptic patients with appropriate-for-gestational-age weight infants. The control group consisted of 54 healthy normotensive pregnant patients with singleton uncomplicated pregnancies. The maternal serum endoglin concentrations were determined using a sandwich enzyme-linked immunosorbent assay assay. Our study revealed increased levels of endoglin in the serum of women with normotensive pregnancy complicated by isolated IUGR, and in both groups of preeclamptic patients with and without IUGR. The levels of endoglin were the highest in pregnancy complicated by fetal intrauterine growth restriction (IUGR) in the course of preeclampsia. The mean values were 12.2 ± 4.3 ng/ml in the IUGR group, 14.1 ± 3.6 ng/ml in preeclamptic patients with normal intrauterine fetal growth, 15.1 ± 3.2 ng/ml in preeclamptic pregnant women with IUGR and 10.6 ± 3.7 ng/ml in the healthy controls. We also found positive correlations between serum endoglin levels and systolic and diastolic blood pressure and inverse correlations between maternal endoglin and infant birth weight. Our results suggest that increased endoglin concentration may be at least responsible for the pathogenesis of preeclampsia and/or intrauterine fetal growth restriction. It seems that the pathomechanism underlying the development of preeclampsia and isolated IUGR is similar, but that their beginning or intensity may be different in these two pregnancy complications. The positive correlation between endoglin and

Full Text Available Abstract Background Pregnancy is an ideal time to encourage healthy lifestyles as most women access health services and are more receptive to health messages; however few effective interventions exist. The aim of this research was to deliver a low-intensity, dietitian-led behavior change workshop at a Maternity Hospital to influence behaviors with demonstrated health outcomes. Methods Workshop effectiveness was evaluated using an RCT; ‘usual care’ women (n = 182 received a nutrition resource at their first antenatal visit and 'intervention' women also attended a one-hour ‘Healthy Start to Pregnancy’ workshop (n = 178. Dietary intake, physical activity levels, gestational weight gain knowledge, smoking cessation, and intention to breastfeed were assessed at service-entry and 12 weeks later. Intention-to-treat (ITT and per-protocol (PP analyses examined change over time between groups. Results Approximately half (48.3% the intervention women attended the workshop and overall response rate at time 2 was 67.2%. Significantly more women in the intervention met pregnancy fruit guidelines at time 2 (+4.3%, p = 0.011 and had a clinically-relevant increase in physical activity (+27 minutes/week compared with women who only received the resource (ITT. Women who attended the workshop increased their consumption of serves of fruit (+0.4 serves/day, p = 0.004, vegetables (+0.4 serves/day, p = 0.006, met fruit guidelines (+11.9%, p , had a higher diet quality score (p = 0.027 and clinically-relevant increases in physical activity (+21.3 minutes/week compared with those who only received the resource (PP. Conclusions The Healthy Start to Pregnancy workshop attendance facilitates improvements in important health behaviors. Service changes and accessibility issues are required to assist women's workshop attendance to allow more women to benefit from the workshop’s effects.

Consistent evidence of an influence of maternal dietary intake during pregnancy on infant body size and composition in human populations is lacking, despite robust evidence in animal models. We sought to evaluate the influence of maternal macronutrient intake and balance during pregnancy on neonatal body size and composition, including fat mass and fat-free mass. The analysis was conducted among 1040 mother-offspring pairs enrolled in the prospective prebirth observational cohort: the Healthy Start Study. Diet during pregnancy was collected using repeated 24-hour dietary recalls (up to 8). Direct measures of body composition were obtained using air displacement plethysmography. The National Cancer Institute measurement error model was used to estimate usual dietary intake during pregnancy. Multivariable partition (nonisocaloric) and nutrient density (isocaloric) linear regression models were used to test the associations between maternal dietary intake and neonatal body composition. The median macronutrient composition during pregnancy was 32.2% from fat, 15.0% from protein, and 47.8% from carbohydrates. In the partition multivariate regression model, individual macronutrient intake values were not associated with birthweight or fat-free mass, but were associated with fat mass. Respectively, 418 kJ increases in total fat, saturated fat, unsaturated fat, and total carbohydrates were associated with 4.2-g (P = .03), 11.1-g (P = .003), 5.9-g (P = .04), and 2.9-g (P = .02) increases in neonatal fat mass, independent of prepregnancy body mass index. In the nutrient density multivariate regression model, macronutrient balance was not associated with fat mass, fat-free mass, or birthweight after adjustment for prepregnancy body mass index. Neonatal adiposity, but not birthweight, is independently associated with increased maternal intake of total fat, saturated fat, unsaturated fat, and total carbohydrates, but not protein, suggesting that most forms of increased

Nutrition, physical activity and lifestyle in pregnancy influence maternal and child health. The "Healthy start - Young Family Network" supported by the German Government with the national action plan IN FORM developed recommendations on nutrition in pregnancy. Folic acid supplements (400 µg/day) should be started before pregnancy and continue for at least the first trimester. Iodine rich foods and salt and an iodine supplement (100-150 µg/day) are recommended. Long-chain omega-3 fatty acids should be provided with ≥ 1 weekly portion of oily sea fish, or a DHA-supplement if regular fish consumption is avoided. Vitamin D supplementation is advisable unless there is regular exposure to sunlight. Iron supplements should be used based on medical history and blood testing. Vegetarian diets with nutritional supplements can provide adequate nutrition, but counselling is recommended. In contrast, a vegan diet is inadequate and requires additional micronutrient supplementation. For risk reduction of listeriosis and toxoplasmosis, raw animal foods, soft cheeses and packed fresh salads should be avoided; fresh fruit, vegetables and salad should be washed well and consumed promptly. Pregnant women should remain physically active and perform sports with moderate intensity. They should avoid alcohol, active and passive smoking. Up to 3 daily cups of coffee are considered harmless, but energy drinks should be avoided. Childhood allergy is not reduced by avoiding certain foods in pregnancy whereas oily sea fish is recommended. Health care professions should lead parents to health-promoting lifestyles. Subjects of part 1 of the article are practice recommendations on nutrition, on energy needs, micronutrient needs and body weight/weight gain in pregnancy. © Georg Thieme Verlag KG Stuttgart · New York.

The course and outcome of 47 singleton pregnancies in women with well-documented PCOD were compared with those in 100 healthy controls. Women with PCOD had a significantly higher body mass index as compared to the control group (P PCOD (P PCOD subjects were compared with lean control subjects, the difference in the incidence of the above complications was still significant (P PCOD subjects were compared with obese controls. Women with PCOD were at increased risk of gestational diabetes and pregnancy-induced hypertension, and this risk appeared to be independent of body mass index.

This study aims to aid in the development of more effective healthy eating intervention strategies for pregnant women by understanding the relationship between healthy eating intention and actual eating behaviour. Specifically, the study explored whether Theory of Planned Behaviour (TPB) constructs [attitude, subjective-norm, perceived-behavioural-control (PBC)] and additional psychosocial variables (perceived stress, health value and self-identity as a healthy eater) are useful in explaining variance in women's 1) intentions to consume a healthy diet during pregnancy and 2) food consumption behaviour (e.g. adherence to food group recommendations) during pregnancy. A cross-sectional sample of 455 Australian pregnant women completed a TPB questionnaire as part of a larger comprehensive web-based nutrition questionnaire. Women's perceived stress, health value and self-identity as a healthy eater were also measured. Dietary intake was assessed using six-items based on the 2013 Australian Dietary Guidelines. Hierarchical multiple linear regression models were estimated (significance level healthy eating intention scores and 12% of the variance in adherence to food group recommendations. TPB constructs explained 66% of the total variance in healthy eating intention. Significant predictors of stronger healthy eating intention were greater PBC and subjective norm, followed by positive attitude and stronger self-identity as a healthy eater. Conversely, TPB constructs collectively explained only 3.4% of total variance in adherence to food group recommendations. These findings reveal that the TPB framework explains considerable variance in healthy eating intention during pregnancy, but explains little variance in actual food consumption behaviour. Further research is required to understand this weak relationship between healthy eating intention and behaviour during pregnancy. Alternative behavioural frameworks, particularly those that account for the automatic nature of most

The persistence of early and closely spaced pregnancies in Northern Nigeria contributes to maternal and child morbidity and mortality. A technical working group to WHO recommended that following a birth, a woman should space her next pregnancy by at least 24 months, and following a miscarriage or abortion, a woman space her next pregnancy by at least six months. UNICEF, UNFPA and WHO also recommend that a woman delay her first pregnancy until 18. These recommendations comprise the concept of Healthy Timing and Spacing of Pregnancy. The Extending Service Delivery Project (ESD) partnered with the Federation of Muslim Women Association of Nigeria and religious leaders to educate communities about the benefits of using family planning to practice HTSP in five local government areas. Informal discussions with 148 women and 28 men found high recall of the HTSP recommendations and favorable attitudes toward spacing and family planning although many remain concerned about the side effects of contraceptive methods.
Full Text Available We are presenting a case report of triplet pregnancy in a 25 years old lady, in whom single fetal reduction was done at 10 weeks. At 29 weeks, ultrasonography showed fetal demise of second twin. Conservative management was done, after evaluating the status of second twin. Maternal and fetal monitoring was done with PT INR, Ultrasound Doppler weekly till 33 weeks when an emergency cesarean was done due to preterm labour pains. A healthy baby of 1.8 kg was born along with a macerated IUD of 500 gms. Mother and baby are healthy on follow up till date. Hence conservative management should be followed in single fetus demise in twin pregnancy with proper monitoring.

To compare perinatal outcomes, maternal outcomes, and interventions in labour by planned place of birth at the start of care in labour for women with low risk pregnancies. Prospective cohort study. England: all NHS trusts providing intrapartum care at home, all freestanding midwifery units, all alongside midwifery units (midwife led units on a hospital site with an obstetric unit), and a stratified random sample of obstetric units. 64,538 eligible women with a singleton, term (≥37 weeks gestation), and "booked" pregnancy who gave birth between April 2008 and April 2010. Planned caesarean sections and caesarean sections before the onset of labour and unplanned home births were excluded. A composite primary outcome of perinatal mortality and intrapartum related neonatal morbidities (stillbirth after start of care in labour, early neonatal death, neonatal encephalopathy, meconium aspiration syndrome, brachial plexus injury, fractured humerus, or fractured clavicle) was used to compare outcomes by planned place of birth at the start of care in labour (at home, freestanding midwifery units, alongside midwifery units, and obstetric units). There were 250 primary outcome events and an overall weighted incidence of 4.3 per 1000 births (95% CI 3.3 to 5.5). Overall, there were no significant differences in the adjusted odds of the primary outcome for any of the non-obstetric unit settings compared with obstetric units. For nulliparous women, the odds of the primary outcome were higher for planned home births (adjusted odds ratio 1.75, 95% CI 1.07 to 2.86) but not for either midwifery unit setting. For multiparous women, there were no significant differences in the incidence of the primary outcome by planned place of birth. Interventions during labour were substantially lower in all non-obstetric unit settings. Transfers from non-obstetric unit settings were more frequent for nulliparous women (36% to 45%) than for multiparous women (9% to 13%). The results support a policy

We tested under which conditions a colour singleton of which an observer is unaware captures attention. To prevent visual awareness of the colour singleton, we used backward masking. We find that a masked colour singleton cue captures attention if it matches the observer's goal to search for target colours but not if it is task-irrelevant. This is also reflected in event-related potentials to the visible target: the masked goal-matching cue elicits an attentional potential (N2pc) in a target search task. By contrast, a non-matching but equally strong masked colour singleton cue failed to elicit a capture effect and an N2pc. Results are discussed with regard to currently pertaining conceptions of attentional capture by colour singletons. Copyright 2010 Elsevier Ltd. All rights reserved.

It is the position of the Academy of Nutrition and Dietetics that women of childbearing age should adopt a lifestyle optimizing health and reducing risk of birth defects, suboptimal fetal development, and chronic health problems in both mother and child.Components leading to healthy pregnancy outcome include healthy pre-pregnancy weight, appropriate weight gain and physical activity during pregnancy, consumption of a wide variety of foods, appropriate vitamin and mineral supplementation, avoidance of alcohol and other harmful substances, and safe food handling. Nutrition assessment needs to encompass changes in anthropometric,biochemical, and clinical indicators throughout pregnancy. Pregnant women should gain weight according to the 2009 Institute of Medicine Guidelines. Energy needs are no higher than the Estimated Energy Requirement for nonpregnant women until the second trimester; thereafter, the extra energy need per day is 340 kcal and 452 kcal in the second and third trimesters,respectively. Using the 2010 Dietary Guidelines for Americans, registered dietitian nutritionists and dietetics technicians, registered,can help pregnant women select a food plan based on age, physical activity, trimester, weight gain, and other considerations.Women are encouraged to participate in at least 150 minutes of moderate-intensity aerobic activity spread throughout the week or 30 minutes of moderately intense exercise on most days of the week.When good food choices are made, food consumption to meet extra energy needs and the increased absorption and efficiency of nutrient utilization that occurs in pregnancy are generally adequate to meet most nutrient needs. However, vitamin and mineral supplementation may be important in vulnerable cases including food insecurity; alcohol, tobacco, or other substance dependency; anemia; strict vegetarian (vegan) diet; or poor eating habits. Multiple strategies are needed to support healthy lifestyles for all women, from preconception

to explore gestational weight gain in healthy women in relation to pre-pregnancy Body Mass Index, diet and physical activity. a cross-sectional survey was conducted among 455 healthy pregnant women of all gestational ages receiving antenatal care from an independent midwife in the Netherlands. Weight gain was assessed using the Institute of Medicine (IOM) guidelines and classified as below, within, or above the guidelines. A multinomial regression analysis was performed with weight gain classifications as the dependent variable (within IOM-guidelines as reference). Independent variables were pre-pregnancy Body Mass Index, diet (broken down into consumption of vegetables, fruit and fish) and physical activity (motivation to engage in physical activity, pre-pregnancy physical activity and decline in physical activity during pregnancy). Covariates were age, gestational age, parity, ethnicity, family income, education, perceived sleep deprivation, satisfaction with pre-pregnancy weight, estimated prepregnancy body mass index, smoking, having a weight gain goal and having received weight gain advice from the midwife. forty-two per cent of the women surveyed gained weight within the guidelines. Fourteen per cent of the women gained weight below the guidelines and 44 per cent gained weight above the guidelines. Weight gain within the guidelines, compared to both above and below the guidelines, was not associated with pre-pregnancy Body Mass Index nor with diet. A decline in physical activity was associated with weight gain above the guidelines (OR 0.54, 95 per cent CI 0.33-0.89). Weight gain below the guidelines was seen more often in women who perceived a greater sleep deprivation (OR 1.20, 95 per cent CI 1.02-1.41). Weight gain above the guidelines was seen less often in Caucasian women in comparison to non-Caucasian women (OR 0.22, 95 per cent CI 0.08-0.56) and with women who did not stop smoking during pregnancy (OR 0.49, 95 per cent CI 0.25-0.95). a decline in

Between 2009 and 2012 there were 26 epilepsy-related deaths in the UK of women who were pregnant or in the first post-partum year. The number of pregnancy-related deaths in women with epilepsy (WWE) has been increasing. Expert assessment suggests that most epilepsy-related deaths in pregnancy were preventable and attributable to poor seizure control. While prevention of seizures during pregnancy is important, a balance must be struck between seizure control and the teratogenic potential of antiepileptic drugs (AEDs). A range of professional guidance on the management of epilepsy in pregnancy has previously been issued, but little attention has been paid to how optimal care can be delivered to WWE by a range of healthcare professionals. We summarise the findings of a multidisciplinary meeting with representation from a wide group of professional bodies. This focussed on the implementation of optimal pregnancy epilepsy care aiming to reduce mortality of epilepsy in mothers and reduce morbidity in babies exposed to AEDs in utero. We identify in particular -What stage to intervene - Golden Moments of opportunities for improving outcomes -Which Key Groups have a role in making change -When - 2020 vision of what these improvements aim to achieve. -How to monitor the success in this field We believe that the service improvement ideas developed for the UK may provide a template for similar initiatives in other countries.

During the postpartum visit, health care providers address issues with short- and long-term implications for maternal and child health. Women with Medicaid insurance are less likely to return for a postpartum visit compared with women with private insurance. Behavioral economics acknowledges that people do not make exclusively rational choices, rather immediate gratification, cognitive and psychological biases, and social norms influence decision making. Drawing on insights from decision science, behavioral economists have examined how these biases can be modulated through carefully designed interventions. We have developed a Web-based tool, Healthy Beyond Pregnancy, that incorporates empirically derived concepts of behavioral economics to improve adherence rates to the postpartum visit. The primary objectives of this pilot study were to (1) refine and assess the usability of Healthy Beyond Pregnancy and (2) assess the feasibility of a randomized controlled trial (RCT) of the intervention. We used a multistep process and multidisciplinary team of maternal-fetal medicine physicians, a behavioral economist, and researchers with expertise in behavioral interventions to design Healthy Beyond Pregnancy. We assessed the usability of the program with the Post-Study System Usability Questionnaire (PSSUQ), a validated 7-point scale, and semistructured interviews with postpartum women. We then conducted a feasibility trial to determine the proportion of eligible women who were willing to participate in an RCT of Healthy Beyond Pregnancy and the proportion of women willing to complete the Web-based program. Exploratory outcomes of the pilot trial included attendance at the postpartum visit, uptake of long-acting reversible contraception, and uptake of any contraception. The median PSSUQ score for Healthy Beyond Pregnancy was 6.5 (interquartile range: 6.1-7) demonstrating high usability. Semistructured interviews (n=10) provided in-depth comments about users' experience and

Full Text Available Maternal immune tolerance of the fetus is indispensible for a healthy pregnancy outcome. Nowhere is this immune tolerance more important than at the fetal-maternal interface – the decidua, the site of implantation and placentation. Indeed, many lines of evidence suggest an immunological origin to the common pregnancy-related disorder, preeclampsia. Within the innate immune system, decidual NK cells and antigen presenting cells (including dendritic cells and macrophages make up a large proportion of the decidual leukocyte population, and are thought to modulate vascular remodeling and trophoblast invasion. On the other hand, within the adaptive immune system, Foxp3+ regulatory T (Treg cells are crucial for ensuring immune tolerance towards the semi-allogeneic fetus. Additionally, another population of CD4+HLA-G+ suppressor T cells has also been identified as a potential player in the maintenance of immune tolerance. More recently, studies are beginning to unravel the potential interactions between the innate and the adaptive immune system within the decidua, that are required to maintain a healthy pregnancy. In this review, we discuss the recent advances exploring the complex crosstalk between the innate and the adaptive immune system during human pregnancy.

People perform better in visual search when the target feature repeats across trials (intertrial feature priming [IFP]). Here, we investigated whether repetition of a feature singleton's color modulates stimulus-driven shifts of spatial attention by presenting a probe stimulus immediately after each singleton display. The task alternated every two trials between a probe discrimination task and a singleton search task. We measured both stimulus-driven spatial attention (via the distance between the probe and singleton) and IFP (via repetition of the singleton's color). Color repetition facilitated search performance (IFP effect) when the set size was small. When the probe appeared at the singleton's location, performance was better than at the opposite location (stimulus-driven attention effect). The magnitude of this attention effect increased with the singleton's set size (which increases its saliency) but did not depend on whether the singleton's color repeated across trials, even when the previous singleton had been attended as a search target. Thus, our findings show that repetition of a salient singleton's color affects performance when the singleton is task relevant and voluntarily attended (as in search trials). However, color repetition does not affect performance when the singleton becomes irrelevant to the current task, even though the singleton does capture attention (as in probe trials). Therefore, color repetition per se does not make a singleton more salient for stimulus-driven attention. Rather, we suggest that IFP requires voluntary selection of color singletons in each consecutive trial.

Objective: To study the variations and influencing factors of serum triglycerides and cholesterol levels during pregnancy and postpartum. Methods: A retrospective study was performed among 5 020 healthy singleton (95.10%, 4 774/5 020) and twin (4.90%, 246/5 020) women who had delivery in Women's Hospital, Zhejiang University School of Medicine from January 2011 to December 2016. Serum triglycerides and cholesterol levels during pregnancy and postpartum of all the cases were collected. Both singleton and twin pregnant women were divided into advanced age and appropriate age groups, and then data of serum sample were assigned to 3 groups according to the gestation weeks, which were second trimester pregnancy (24-28 gestation weeks) , third trimester pregnancy (32-41 gestation weeks) and postpartum (within 72 hours after delivery) . The serum triglycerides and cholesterol levels in each groups were compared. Results: (1) Serum triglycerides and cholesterol levels during the second trimester pregnancy, third trimester pregnancy and postpartum were higher than levels of non-pregnancy in both singleton and twin groups (all Ppregnancy group were higher than those of second trimester pregnancy group in both advanced age and appropriate aged women regardless singleton or twin pregnancy (all Ppregnancy were as follows: in appropriate aged singleton group, the triglycerides levels were 1.07-4.13 and 1.52-7.21 mmol/L, and the cholesterol levels were 2.77-12.11 and 4.44-9.36 mmol/L. In advanced aged singleton group, the triglycerides levels were 1.28-4.61 and 1.70-7.80 mmol/L, and the cholesterol levels were 4.35-8.40 and 4.46-9.35 mmol/L; in appropriate aged twin group, the triglycerides levels were 1.39-7.16 and 1.90-9.29 mmol/L, and the cholesterol levels were 4.99-12.16 and 4.52-10.07 mmol/L; in advanced aged twin group, the triglycerides levels were 1.61-5.32 and 1.94-9.29 mmol/L, and the cholesterol levels were 5.24-8.10 and 4.53-8.86 mmol/L.

To describe and evaluate recruitment techniques used to enroll 152 healthy pregnant women fewer than 15 weeks gestation into a prospective study of environmental chemical exposure during pregnancy. Posters, a website, online and print advertising, recruitment emails, media coverage, recruitment from clinic waiting rooms, networking within the pregnancy community and presenting a study booth at baby "trade shows" were used to advertise the study. Participants had to meet a strict set of eligibility criteria, and were asked to donate two-second-trimester blood samples, complete two questionnaires, have samples of air, dust, lint and tap water collected from their homes, and donate a cord blood sample at delivery. Over 17 months, 171 women enrolled (49% of initial contacts, and 99% of all eligible women) and 152 women completed the study (89% retention). Total recruitment costs were approximately $400 Cdn per final participant. Posters, study booth presentations and online advertising generated the most inquiries about the study. Word of mouth, referral from another study and direct email were the most cost-effective strategies. Not surprisingly, the recruited study population was less ethnically diverse, more affluent and more educated than the background population of pregnant women in Vancouver. A combination of passive and active recruitment techniques were successful for recruiting healthy women in roughly the first trimester of pregnancy (<15 weeks gestation). While a convenience sample of women is suitable for our study questions, additional strategies may be required to recruit a more representative pregnant population in future studies.

Maternal distress is a public health concern. Assessment of emotional wellbeing is not integrated in Dutch antenatal care. Midwives need to understand the influencing factors in order to identify women who are more vulnerable to experience maternal distress. To examine levels of maternal distress during pregnancy and to determine the relationship between maternal distress and aetiological factors. A cross-sectional study including 458 Dutch-speaking women with uncomplicated pregnancies during all trimesters of pregnancy. Data were collected with questionnaires between 10 September and 6 November 2012. Demographic characteristics and personal details were obtained. Maternal distress was measured with the Edinburgh Depression Scale (EDS), State-Trait Anxiety Inventory (STAI), and Pregnancy-Related Anxiety Questionnaire (PRAQ). Behaviour was measured with Coping Operations Preference Enquiry-Easy (COPE-Easy). Descriptive statistics and multiple linear regression analysis were used. Just over 20 percent of the women in our sample (21.8%) had a heightened score on one or more of the EDS, STAI or PRAQ.

Poor diet quality is common among low-income, overweight, African-American mothers, placing them at high risk for adverse pregnancy outcomes. We sought to better understand the contextual factors that may influence low-income African-American mothers' diet quality during pregnancy. In 2011, we conducted semi-structured interviews with 21 overweight/obese, pregnant African Americans in Philadelphia, PA, all of whom received Medicaid and were eligible for the Special Supplemental Nutrition Program for Women, Infants, and Children. Two readers independently coded the interview transcripts to identify recurrent themes. We identified 10 themes around motivators and barriers to healthy eating in pregnancy. Mothers believed that consuming healthy foods, like fruits and vegetables, would lead to healthy babies and limit the physical discomforts of pregnancy. However, more often than not, mothers chose foods that were high in fats and sugars because of taste, cost, and convenience. In addition, mothers had several misconceptions about the definition of healthy (eg, "juice is good for baby"), which led to overconsumption. Many mothers feared they might "starve" their babies if they did not get enough to eat, promoting persistent snacking and larger portions. Living in multigenerational households and sharing resources also limited the mothers' control over food choices and made consuming healthy foods especially difficult. Despite the good intentions of low-income African-American mothers to improve diet quality during pregnancy, multiple factors worked together as barriers to healthy eating. Interventions that emphasize tasty and affordable healthy food substitutes, address misconceptions, and counsel mothers about true energy needs in pregnancy may improve low-income, African-American, overweight/obese mothers' diet quality.

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

This study assessed if upright cycling is preferable to semi-recumbent cycling during pregnancy. Healthy women with low risk singleton pregnancies were tested at 34-38 weeks gestation. They cycled for 12 min, either semi-recumbent (45 degrees, n = 27) or upright (n = 23), at 135-145 beats min(-1). When semi-recumbent, minute ventilation was greater (pposture-independent. All increased with exercise (p0.05). Small post-exercise fetal heart rate increases (by 8 beats min(-1), ppostures (n = 11 in each sub-group), with no adverse changes. Fetal heart rate accelerations and uterine activity (n = 11 in each sub-group) were not influenced by posture or exercise. (1) Neither posture had a distinct advantage. (2) Both postures were safe for short duration cycling. (3) The same target maternal heart rates are suitable for both postures because they resulted in similar oxygen consumptions and fetal heart rates.

A high infant birthweight is associated with future risk of a range of adverse health consequences. This study sought to determine whether maternal "junk food" diet (energy-dense, nutrient-poor) predicts high birthweight in first-time mothers in southwest Sydney, Australia. A community-based longitudinal study was conducted with a total of 368 first-time mothers and their newborns. Information about maternal "junk food" diet, including high consumption of soft drink, fast food, and/or processed meat and chips, and self-reported prepregnant weight and height of first-time mothers was collected by a face-to-face interview with mothers between 24 and 34 weeks of pregnancy. Birthweight was measured in hospital and reported by the mother, together with gestational age, when the baby was 6 months old. Logistic regression modeling was used to determine the factors predicting birthweight greater than 4.0 kg. Eleven percent of newborns weighed more than 4.0 kg (12% boys, 9% girls). Compared with mothers who had a "junk food" diet, mothers who had not consumed "junk food" during pregnancy were significantly less likely to have a newborn weighing more than 4.0 kg, with adjusted odds ratio (AOR) 0.36, 95 percent confidence interval (CI) 0.14-0.91, p = 0.03, after adjusting for maternal weight status and gestational age. Compared with healthy and underweight mothers, overweight or obese mothers were more likely to have a newborn weighing more than 4.0 kg (AOR overweight 3.03, 95% CI 1.35-6.80; obese 3.79, 95% CI 1.41-10.25) after allowing for "junk food" diet and gestational age. Maternal "junk food" diet during pregnancy and prepregnant overweight and obesity were independent predictors of high infant birthweight. Early childhood obesity interventions should consider addressing these factors. © 2013, Copyright the Authors Journal compilation © 2013, Wiley Periodicals, Inc.

Previous research has revealed that people can suppress salient stimuli that might otherwise capture visual attention. The present study tests between 3 possible mechanisms of visual suppression. According to first-order feature suppression models , items are suppressed on the basis of simple feature values. According to second-order feature suppression models , items are suppressed on the basis of local discontinuities within a given feature dimension. According to global-salience suppression models , items are suppressed on the basis of their dimension-independent salience levels. The current study distinguished among these models by varying the predictability of the singleton color value. If items are suppressed by virtue of salience alone, then it should not matter whether the singleton color is predictable. However, evidence from probe processing and eye movements indicated that suppression is possible only when the color values are predictable. Moreover, the ability to suppress salient items developed gradually as participants gained experience with the feature that defined the salient distractor. These results are consistent with first-order feature suppression models, and are inconsistent with the other models of suppression. In other words, people primarily suppress salient distractors on the basis of their simple features and not on the basis of salience per se.

Full Text Available Abstract Background The haematological profile of the pregnant woman has an impact on the outcome of the pregnancy. Published guidelines indicate acceptable levels for haematological indices in pregnancy but they are population specific. Indicators of haemoglobin concentration are the most commonly utilized of the indices. These published international norms are used across populations, however, there is no evidence confirming their applicability to a population such as the Jamaican pregnant woman. This study was therefore undertaken with the intent of documenting the haematological profile of pregnant primigravid Jamaican women and comparing these to the established norms to determine whether the norms apply or whether there was a need to establish local norms. Methods This was a longitudinal study done on a cohort of 157 healthy primigravid women ages 15 to 25 and without anaemia, and who were recruited from the antenatal clinic of the University Hospital of the West Indies, Kingston, Jamaica. The haemoglobin concentration, packed cell volume, mean cell volume, mean cell haemoglobin, mean cell haemoglobin concentration, white blood cell count, red blood cell count and platelet count were measured on samples of blood obtained from each consenting participant during each of the three trimesters. The results were analysed using SPSS for windows (Version 11 and the data expressed as means ± S.D. Means were compared using the student's paired t-test. Comparison was then made with the international norms as recommended by the United States Center for Disease Control (1989. Ethical approval for this study was obtained from the University Hospital of the West Indies/University of the West Indies Ethics Committee. Results The results showed changes by trimester in all measured variables. For most of the indices the changes achieved levels of significance across trimesters. These changes were however in keeping with the expected physiological response

Placenta previa has been associated with adverse birth outcomes, but its association with congenital malformations is inconclusive. We examined the association between placenta previa and major congenital malformations among singleton births in Finland. We performed a retrospective population register-based study on all singletons born at or after 22+0 weeks of gestation in Finland during 2000 to 2010. We linked three national health registers: the Finnish Medical Birth Register, the Hospital Discharge Register, and the Register of Congenital Malformations, and examined several demographic and clinical characteristics among women with and without placenta previa, in association with major congenital malformations. We estimated adjusted odds ratios and 95% confidence intervals using multivariable logistic regression models. The prevalence of placenta previa was estimated as 2.65 per 1000 singleton births in Finland (95% confidence interval, 2.53-2.79). Overall, 6.2% of women with placenta previa delivered a singleton infant with a major congenital malformation, compared with 3.8% of unaffected women (p ≤ 0.001). Placenta previa was positively associated with almost 1.6-fold increased risk of major congenital malformations in the offspring, after controlling for maternal age, parity, fetal sex, smoking, socio-economic status, chorionic villus biopsy, In vitro fertilization, pre-existing diabetes, depression, preeclampsia, and prior caesarean section (adjusted odds ratio = 1.55; 95% confidence interval, 1.27-1.90). Using a large population-based study, we found that placenta previa was weakly, but significantly associated with an increased risk of major congenital malformations in singleton births. Future studies should examine the association between placenta previa and individual types of congenital malformations, specifically in high-risk pregnancies. © 2015 Wiley Periodicals, Inc.

Is there a difference in birthweight distribution in ART singletons born after IVF culture in two different culture media? There is no effect of culture media on both crude and adjusted birthweight distributions in ART singletons from nulliparous mothers. Studies on human ART singletons have reported a difference in birthweight in singletons following IVF culture in different culture media. However, other studies comparing different culture media have not shown any significant differences in birthweight. This study was a retrospective comparison of birthweights in IVF/ICSI singletons conceived after fresh embryo transfer following embryo culture in Cook or Medicult medium and in a national cohort of naturally conceived singletons in nulliparous women. The study compares four independent groups consisting of singletons in nulliparous women from Cook-d2: 2-day culture in Cook medium at Rigshospitalet (n = 974), Medicult-d2: 2-day culture in Medicult EmbryoAssist medium at Rigshospitalet (n = 147), Medicult-d3: 3-day culture in Medicult EmbryoAssist medium with and without added GM-CSF (n = 204), and DK: pregnancies from the Danish birth registry (n = 106842). The study compares the birthweights of singletons from nulliparous women in the four independent groups mentioned above; Cook-d2: Medicult-d2: Medicult-d3: and DK. In addition, distributions of large and small for gestational age infants were compared between the groups and a multiple linear regression analysis was used to determine which factors determined birthweight. We found no significant difference in the crude birthweight distributions between singletons born after culture in Cook-d2 or Medicult-groups. Singleton girls from the Cook-d2 group weighed 3302 ± 28 g, versus 3252 ± 76 in the Medicult-d2 group (difference 50 g; P = 0.547). Singleton boys from the Cook-d2 group weighed 3430 ± 27 g, versus 3354 ± 56 in the Medicult-d2 group (difference 76 g; P = 0.279). In the background population, mean

Full Text Available Abstract Background Magnetocardiography enables the precise determination of fetal cardiac time intervals (CTI as early as the second trimester of pregnancy. It has been shown that fetal CTI change in course of gestation. The aim of this work was to investigate the dependency of fetal CTI on gestational age, gender and postnatal biometric data in a substantial sample of subjects during normal pregnancy. Methods A total of 230 fetal magnetocardiograms were obtained in 47 healthy fetuses between the 15th and 42nd week of gestation. In each recording, after subtraction of the maternal cardiac artifact and the identification of fetal beats, fetal PQRST courses were signal averaged. On the basis of therein detected wave onsets and ends, the following CTI were determined: P wave, PR interval, PQ interval, QRS complex, ST segment, T wave, QT and QTc interval. Using regression analysis, the dependency of the CTI were examined with respect to gestational age, gender and postnatal biometric data. Results Atrioventricular conduction and ventricular depolarization times could be determined dependably whereas the T wave was often difficult to detect. Linear and nonlinear regression analysis established strong dependency on age for the P wave and QRS complex (r2 = 0.67, p r2 = 0.66, p r2 = 0.21, p r2 = 0.13, p st week onward (p Conclusion We conclude that 1 from approximately the 18th week to term, fetal CTI which quantify depolarization times can be reliably determined using magnetocardiography, 2 the P wave and QRS complex duration show a high dependency on age which to a large part reflects fetal growth and 3 fetal gender plays a role in QRS complex duration in the third trimester. Fetal development is thus in part reflected in the CTI and may be useful in the identification of intrauterine growth retardation.

We developed and tested in a cluster RCT a theory-driven group-based intervention for obese pregnant women. It was designed to support women to moderate weight gain during pregnancy and reduce BMI one year after birth, in addition to targeting secondary health and wellbeing outcomes. In line with MRC guidance on developing and evaluating complex interventions in health, we conducted a process evaluation alongside the trial. This paper describes the development of the process evaluation framework. This cluster RCT recruited 598 pregnant women. Women in the intervention group were invited to attend a weekly weight-management group. Following a review of relevant literature, we developed a process evaluation framework which outlined key process indicators that we wanted to address and how we would measure these. Central to the process evaluation was to understand the mechanism of effect of the intervention. We utilised a logic-modelling approach to describe the intervention which helped us focus on what potential mediators of intervention effect to measure, and how. The resulting process evaluation framework was designed to address 9 core elements; context, reach, exposure, recruitment, fidelity, recruitment, retention, contamination and theory-testing. These were assessed using a variety of qualitative and quantitative approaches. The logic model explained the processes by which intervention components bring about change in target outcomes through various mediators and theoretical pathways including self-efficacy, social support, self-regulation and motivation. Process evaluation is a key element in assessing the effect of any RCT. We developed a process evaluation framework and logic model, and the results of analyses using these will offer insights into why the intervention is or is not effective. Copyright © 2014.

Birth outcomes tend to be better among Hispanics than among other ethnic groups, even when matched for poverty and education, and foreign-born Latinas compared to their US-born counterparts. These patterns suggest that sociocultural factors exhibited by recent immigrants have the potential to protect birth outcomes against the instability of minority and low socioeconomic status. To discover potential sociocultural factors, a pilot qualitative study was carried out in Tucson, Arizona, with 18 Hispanic mothers. The two most prevalent factors reported were (1) a healthy diet prepared at home from minimally processed ingredients, and (2) constant and comprehensive social support. When comparing responses related to diet by interview language preference, a proxy for acculturation, there was very little difference between participants who interviewed in Spanish and those who interviewed in English. This result may be explained by greater maternal social support and higher education levels among those who interviewed in English.

Few women report being advised on GWG, physical activity (PA, and nutrition, yet the majority of health care providers report discussing these topics with patients. We evaluated whether various Canadian maternal health care providers can identify appropriate GWG targets for patients with obesity and determine if providers report counseling on GWG, physical activity, and nutrition. Methods: A valid and reliable e-survey was created using SurveyMonkey software and distributed by the Society of Obstetricians and Gynaecologists of Canada listserve. A total of 174 health care providers finished the survey. Respondents self-identified as general practitioners, obstetricians, maternal-fetal medicine specialists, midwives, or registered nurses. Results: GWG recommendations between disciplines for all body mass index categories were similar and fell within Health Canada/Institute of Medicine (IOM guidelines. Of those who answered this question, 110/160 (68.8% were able to correctly identify the maximum IOM GWG recommended for patients with obesity, yet midwives tended to recommend 0.5–1 kg more GWG (P = 0.05. PA counseling during pregnancy differed between disciplines (P < 0.01, as did nutrition counseling during pregnancy (P < 0.05. Conclusion: In
Full Text Available Abstract Background Pregnancy is accompanied by several hemodynamic, biochemical and hematological changes which revert to normal values after labor. The mean values of these parameters have been reported for developed countries, but not for Mexican women. Furthermore, labor constitutes a stress situation, in which these factors may be altered. It is known that serologic increase of heat shock protein (Hsp 70 is associated with abnormal pregnancies, presenting very low level in normal pregnant women. Nevertheless, there are no studies where these measurements are compared in healthy pregnant women at their third trimester of pregnancy (3TP and the active labor phase (ActLP. Methods Seventy five healthy Mexican pregnant women were included. Hemodynamic, biochemical and hematological parameters were obtained in all cases, and serum Hsp70 levels were measured in a sample of 15 women at 3TP and at ActLP. Results Significant differences were found in most analysis performed and in Hsp70 concentration at 3TP as compared to ActLP, however all were within normal range in both conditions, supporting that only in pathological pregnancies Hsp70 is drastically increased. Conclusion Results obtained indicate that 3TP and ActLP have clinical similarities in normal pregnancies, therefore if abnormalities are found during 3TP, precautions should be taken before ActLP.

Full Text Available Abstract Background Eating a diet that is high in fat and sugar and having a sedentary lifestyle during pregnancy is understood to increase the risk of excessive gestational weight gain and obesity following the birth of the baby. However, there are no clinical guidelines in the UK on what is considered to be appropriate gestational weight gain. Indeed, clinical recommendations discourage the routine re-weighing of pregnant women, stating instead that women should be advised regarding their diet and activity levels, in order to prevent excessive weight gain. Pregnancy is seen as a time when many women may have an increased motivation to improve their lifestyle behaviours for the benefit of the fetus. However, it is evident that many women have difficulty in both maintaining a healthy balanced diet and remaining active through pregnancy. It would seem that midwives may be ideally placed to assist women to make and maintain healthier lifestyle choices during pregnancy. Methods/design This study will look at the feasibility and acceptability of a newly devised intervention programme called 'Eat Well Keep Active'. Participants will complete a questionnaire prior to the programme to obtain baseline data on food frequency, physical activity and to gauge their perception of personal ability to improve/maintain healthy lifestyle. The programme comprises client centred techniques; motivational interviewing and goal setting delivered early in pregnancy (12-16 weeks with the aim of supporting a healthy well balanced diet and either continuing or commencing appropriate levels of physical activity.

Full Text Available BACKGROUND: Pregnancy induces physiological adaptations that may involve, or contribute to, alterations in the genomic landscape. Pregnancy also increases the nutritional demand for choline, an essential nutrient that can modulate epigenomic and transcriptomic readouts secondary to its role as a methyl donor. Nevertheless, the interplay between human pregnancy, choline and the human genome is largely unexplored. METHODOLOGY/PRINCIPAL FINDINGS: As part of a controlled feeding study, we assessed the influence of pregnancy and choline intake on maternal genomic markers. Healthy third trimester pregnant (n = 26, wk 26-29 gestation and nonpregnant (n = 21 women were randomized to choline intakes of 480 mg/day, approximating the Adequate Intake level, or 930 mg/day for 12-weeks. Blood leukocytes were acquired at study week 0 and study week 12 for microarray, DNA damage and global DNA/histone methylation measurements. A main effect of pregnancy that was independent of choline intake was detected on several of the maternal leukocyte genomic markers. Compared to nonpregnant women, third trimester pregnant women exhibited higher (P<0.05 transcript abundance of defense response genes associated with the innate immune system including pattern recognition molecules, neutrophil granule proteins and oxidases, complement proteins, cytokines and chemokines. Pregnant women also exhibited higher (P<0.001 levels of DNA damage in blood leukocytes, a genomic marker of oxidative stress. No effect of choline intake was detected on the maternal leukocyte genomic markers with the exception of histone 3 lysine 4 di-methylation which was lower among pregnant women in the 930 versus 480 mg/d choline intake group. CONCLUSIONS: Pregnancy induces transcriptional activation of the peripheral innate immune system and increases oxidative DNA damage among healthy third trimester pregnant women.

Does the type of in vitro culture medium or the duration of in vitro culture influence singleton birthweight after IVF/ICSI treatment? In a comparison of two culture media, neither the medium nor the duration of culture (Day 3 versus Day 5 blastocyst transfer) had any effect on mean singleton birthweight. Previous studies indicated that in vitro culture of human embryos may affect birthweight of live born singletons. Both the type of culture medium and the duration of culture may be implicated. However, these studies are small and report conflicting results. A large retrospective analysis was performed including all singleton live births after transferring fresh Day 3 or Day 5 embryos. IVF and ICSI cycles performed between April 2004 and December 2009 at a tertiary care centre were included for analysis. A total of 2098 singleton live births resulting from singleton pregnancies were included for analysis. Two different sequential embryo culture media were concurrently used in an alternating way: Medicult (n = 1388) and Vitrolife (n = 710). Maternal age, maternal and paternal BMI, maternal parity, maternal smoking, main cause of infertility, cycle rank, stimulation protocol, method of fertilization (IVF or ICSI), time in culture and number of embryos transferred were taken into account. Embryo transfers were performed either on Day 3 (n = 1234) or on Day 5 (n = 864). Singleton birthweight was the primary outcome parameter. Gestational age and gender of the newborn were accounted for in the multiple regression analysis. No significant differences in mean singleton birthweight were observed between the two culture media: Medicult 3222 g (±15 SE) and Vitrolife 3251 g (±21 SE) (P = 0.264). The mean singleton birthweight was not different between Day 3 embryo transfers (3219 ± 16 g) and Day 5 blastocyst transfers (3250 ± 19 g; P = 0.209). Multiple regression analysis controlling for potential maternal, paternal, treatment and newborn confounders confirmed the non

To estimate the gestational age and birth weight centiles of babies delivered normally, without any obstetric intervention, in women with uncomplicated singleton pregnancies establishing spontaneous onset of labour. Consecutive women with uncomplicated singleton pregnancies, attending the Academic Obstetrics and Gynecology Unit of the Teaching Hospital Mahamodara Galle, Sri Lanka, with confirmed dates and establishing spontaneous onset of labor and delivering vaginally between gestational age of 34 - 41 weeks, without any obstetric intervention , during the period September 2013 to February 2014 were studied. The gestational age at spontaneous onset of labor and vaginal delivery and the birth weights of the babies were recorded. There were 3294 consecutive deliveries during this period, and of them 1602 (48.6%) met the inclusion criteria. Median gestational age at delivery was 275 days (range 238-291 days, IQR 269 to 280 days) and the median birth weight was 3000 g (range1700g - 4350g; IQR 2750-3250g). The 10th, 50th and 90th birth weight centiles of the babies delivered at a gestational age of 275 days were approximately 2570g, 3050g and 3550g respectively. The median gestational age among women with uncomplicated singleton pregnancies who established spontaneous onset of labor and delivered vaginally, without any obstetric intervention, was approximately five days shorter than the traditionally accepted 280 days. At a gestational age of 275 days, the mean birth weight was approximately 3038g and the 50th centile of the birth weight of the babies delivered was approximately 3050g.

Iatrogenic twinning has become the main side-effect assisted reproduction treatment. We have evaluated the evidence for additional care that assisted-reproduction twins may require compared with spontaneous twins. Misacarriages are increased in women with tubal problems and after specific treatments. Assisted-reproduction twin pregnancies complicated by a vanishing twin after 8 weeks have an increased risk of preterm delivery and of low and very low birthweight compared with singleton assisted-reproduction pregnancies. Monozygotic twin pregnancies occur at a higher rate after assisted reproduction treatment and are associated with a higher risk of perinatal complications. The incidence of placenta praevia and vasa praevia is increased in assisted-reproduction twin pregnancies. Large cohort studies do not indicate a higher rate of fetal congenital malformations in assisted-reproduction twins. Overall, assisted-reproduction twins in healthy women assisted-reproduction twins is only increased in women with a pre-existing medical condition such as hypertensive disorders and diabetes and most of these risks can be avoided with single-embryo transfer. Following the birth of the first IVF baby, rumours started to spread in both the medical literature and the media about the long-term health effects for children born following assisted reproduction treatment. However, after more than 30 years, the most common complications associated with IVF treatment remain indirect and technical such as the failure of treatment and ovarian hyperstimulation. Iatrogenic twinning has become the main side-effect of assisted reproduction treatment and the increasing number of twin pregnancies, in particular in older women, has generated numerous debates on the need for additional healthcare provision. In this review, we have evaluated the evidence for additional care that assisted-conception twin pregnancies may require compared with spontaneous twin pregnancies. Twin pregnancies are

Many complications of pregnancy and delivery are associated with umbilical cord length. It is important to examine the variation in length, in order to identify normal and abnormal conditions. Moreover, the factors influencing cord growth and development are not precisely known. The main objectives were to provide updated reference charts for umbilical cord length in singleton pregnancies and to evaluate potential factors affecting cord length. Birth register data of 47,284 singleton pregnant women delivering in Kuopio University Hospital, Finland was collected prospectively. Gender-specific centile charts for cord length from 22 to 44 gestational weeks were obtained using generalized additive models for location, scale, and shape (GAMLSS). Gestational, fetal, and maternal factors were studied for their potential influence on cord length with single variable analysis and stepwise multiple linear regression analysis. Cord length increased according to gestational age, while the growth decelerated post-term. Birth weight, placental weight, pregravid maternal body mass index, parity, and maternal age correlated to cord length. Gestational diabetes and previous miscarriages were associated with longer cords, while female gender and placental abruption were associated with shorter cords. Girls had shorter cords throughout gestation although there was substantial variation in length in both genders. Cord length associated significantly with birth weight, placental weight, and gestational age. Significantly shorter cords were found in women with placental abruption. This important finding requires further investigation. Copyright © 2014 Elsevier Ltd. All rights reserved.

Preservation of fertility is a major concern for premenopausal women after diagnosis of cervical cancer. Successful surrogate pregnancy after treatment for cervical cancer has very rarely been reported. In the present report, a case of successful surrogate pregnancy after radical hysterectomy, lymphadenectomy and ovarian transposition for cervical cancer, followed by radiation therapy, is presented. After stimulation of the transposed ovaries using the short gonadotrophin-releasing hormone (GnRH) analogue protocol, four oocytes were retrieved transabdominally from the genetic mother. IVF followed and two embryos were transferred to the surrogate mother, leading to an uneventful singleton pregnancy, and ultimately normal vaginal delivery of a healthy female infant at term. The unique aspect in this case is the long-lasting favourable outcome for both genetic mother and child, observed during 8.5 years of follow-up, the longest follow-up period reported to date in such cases.

Improved maternal nutrition and glycaemic control before and during pregnancy are thought to benefit the health of the mother, with consequent benefits for infant body composition and later obesity risk. Maternal insulin resistance and glycaemia around conception and in early pregnancy may be key determinants of maternal physiology and placental function, affecting fetal nutrient supply and maternal-feto-placental communications throughout gestation, with implications for later postnatal health. This double-blind randomised controlled trial will recruit up to 1800 women, aged 18-38 years, who are planning a pregnancy in the United Kingdom (UK), Singapore and New Zealand, with a view to studying 600 pregnancies. The primary outcome is maternal glucose tolerance at 28 weeks' gestation following an oral glucose tolerance test. Secondary outcomes include metabolic, molecular and health-related outcomes in the mother and offspring, notably infant body composition. Participants will be randomly allocated to receive a twice-daily control nutritional drink, enriched with standard micronutrients, or a twice-daily intervention nutritional drink enriched with additional micronutrients, myo-inositol and probiotics, both demonstrated previously to assist in maintaining healthy glucose metabolism during pregnancy. Myo-inositol is a nutrient that enhances cellular glucose uptake. The additional micronutrients seek to address deficiencies of some B-group vitamins and vitamin D that are both common during pregnancy and that have been associated with maternal dysglycaemia, epigenetic changes and greater offspring adiposity. Women who conceive within a year of starting the nutritional drinks will be followed through pregnancy and studied with their infants at six time points during the first year of life. Blood, urine/stool, hair and cheek swabs will be collected from the mothers for genetic, epigenetic, hormone, nutrient and metabolite measurements, and assessments of the mother

Maternal stress during pregnancy is associated with birth outcomes, including birthweight. Exposure to natural disasters during pregnancy provides a model to study these relationships. However, few studies assess both stress and diet, which might have interactive effects. Furthermore, most are conducted in high-income countries. Patterns might differ in low- and middle-income countries (LMICs). To study relationships between stress and diet during pregnancy, and infant birthweight, following a natural disaster in a lower-middle income country. In 2015, the island nation of Vanuatu suffered a Category 5 cyclone. Three months later, the authors assessed hardship due to the cyclone, distress, and dietary diversity among 900 women, including 187 pregnant women. Of these, 70 had birth records available. Multivariate linear regression was used to analyse relationships between cyclone exposure and infant birthweight among this sub-sample. Neither hardship nor dietary diversity predicted birthweight. Distress was a robust predictor, explaining 8.5% of variance (p = 0.012). There were no interactive relationships between distress and other exposure variables. Maternal distress following a natural disaster has important implications for maternal and child health. In LMICs, low birthweight remains a pressing public health concern. Distress during pregnancy might represent one underlying risk factor.

Previous work on attentional capture has shown the attentional system to be quite flexible in the stimulus properties it can be set to respond to. Several different attentional "modes" have been identified. Feature search mode allows attention to be set for specific features of a target (e.g., red). Singleton detection mode sets attention to respond to any discrepant item ("singleton") in the display. Relational search sets attention for the relative properties of the target in relation to the distractors (e.g., redder, larger). Recently, a new attentional mode was proposed that sets attention to respond to any singleton within a particular feature dimension (e.g., colour; Folk & Anderson, 2010). We tested this proposal against the predictions of previously established attentional modes. In a spatial cueing paradigm, participants searched for a colour target that was randomly either red or green. The nature of the attentional control setting was probed by presenting an irrelevant singleton cue prior to the target display and assessing whether it attracted attention. In all experiments, the cues were red, green, blue, or a white stimulus rapidly rotated (motion cue). The results of three experiments support the existence of a "colour singleton set," finding that all colour cues captured attention strongly, while motion cues captured attention only weakly or not at all. Notably, we also found that capture by motion cues in search for colour targets was moderated by their frequency; rare motion cues captured attention (weakly), while frequent motion cues did not.

The cesarean section rate (CSR) has been a main concern worldwide. The present study aimed to investigate the CSR in Beijing, China, and to analyze the related factors of CS delivery. An observational study was conducted in 15 medical centers in Beijing using a systemic cluster sampling method. In total, 15,194 pregnancies were enrolled in the study between June 20, 2013 and November 30, 2013. Independent t-tests and Pearson's Chi-square test were used to examine differences between two groups, and related factors of the CSR were examined by multivariable logistic regression. The CSR was 41.9% (4471/10,671) in singleton primiparae. Women who were more than 35 years old had a 7.4-fold increased risk of CS delivery compared with women level. Neonates weighing 3000-3499 g had the lowest CSR (36.2%). Neonates weighing levels, residence, education level, and singleton fetal birth weight are all factors that might significantly affect the CSR.

From early pregnancy, maternal hemodynamic profile begins to change. The absence of these changes leads to increased risk of complication during the gestation. Aim of this study is to understand in early pregnancy the behaviour of total vascular resistances (TVR) as a sign of maternal cardiovascular adaptation to pregnancy. A cross section study was conducted. We followed 160 healthy women with singleton pregnancy during the first trimester of gestation. We evaluated cardiac output (CO) and TVR at 7, 9 and 11 weeks of gestation. We obtained the following haemodynamic measurements with the USCOM system, a non invasive method: heart rate (HR), systolic and diastolic blood pressure (SBP, DBP), CO and TVR. 160 healthy pregnant women were selected, 8 patients, were excluded for a bad signal. Absolute values of the haemodynamic measures are shown in Fig. 1. 41 patients underwent spontaneous embryonic demise. This last group of patients showed in 54% (group A) TVR values within the normal limits (TVR1200) and CO values below the normal adaptation to pregnancy. Table 1 shows hemodynamic measures for the group A and group B; we found differences in term of CO, TVR and PAS between the two groups. Elevated TVR might indicate an abnormal vascular adaptation already in first weeks of pregnancy. Moreover, in women who undergo to abortion, elevated TVR could be use to distinguish genetic or environmental causes of miscarriage. Copyright © 2013. Published by Elsevier B.V.

To quantify the association between a combination of healthy lifestyle factors before pregnancy (healthy body weight, healthy diet, regular exercise, and not smoking) and the risk of gestational diabetes. Prospective cohort study. Nurses' Health Study II, United States. 20,136 singleton live births in 14,437 women without chronic disease. Self reported incident gestational diabetes diagnosed by a physician, validated by medical records in a previous study. Incident first time gestational diabetes was reported in 823 pregnancies. Each lifestyle factor measured was independently and significantly associated with risk of gestational diabetes. The combination of three low risk factors (non-smoker, ≥ 150 minutes a week of moderate to vigorous physical activity, and healthy eating (top two fifths of Alternate Healthy Eating Index-2010 adherence score)) was associated with a 41% lower risk of gestational diabetes compared with all other pregnancies (relative risk 0.59, 95% confidence interval 0.48 to 0.71). Addition of body mass index (BMI) diabetes compared with all other pregnancies (relative risk 0.48, 0.38 to 0.61). Compared with pregnancies in women who did not meet any of the low risk lifestyle factors, those meeting all four criteria had an 83% lower risk of gestational diabetes (relative risk 0.17, 0.12 to 0.25). The population attributable risk percentage of the four risk factors in combination (smoking, inactivity, overweight, and poor diet) was 47.5% (95% confidence interval 35.6% to 56.6%). A similar population attributable risk percentage (49.2%) was observed when the distributions of the four low risk factors from the US National Health and Nutrition Examination Survey (2007-10) data were applied to the calculation. Adherence to a low risk lifestyle before pregnancy is associated with a low risk of gestational diabetes and could be an effective strategy for the prevention of gestational diabetes. © Zhang et al 2014.

To determine the normal reference values for antithrombin (AT) activity, platelet count (Plt), hemoglobin concentration (Hb), and hematocrit value (Ht) immediately before vaginal delivery among healthy pregnant women with singleton pregnancies and to determine association of these blood parameters with fetal growth. A complete blood count was performed and the AT activity was examined in 300 consecutive women admitted to hospital at > or = gestational week 36 for labor pains and/or the rupture of fetal membranes. All the women were normotensive and had singleton pregnancies, and none of the women had proteinuria, a weekly weight gain > or = 0.5 kg, or other specific complications upon admission. All the women attempted a vaginal delivery. The medians (5th-95th percentile) were 90% (71-110%) for AT activity, 234x10(9)/L (150-337x10(9)/L) for Plt, 11.0 g/dL (9.5-12.8 g/dL) for Hb, and 34.0% (30.4-38.6%) for Ht. Women with an Hb value of > or = the median (11.0 g/dL) gave birth to significantly smaller infants than their counterparts. A considerable number of healthy women exhibit a reduced AT activity and/or platelet count immediately before delivery. Hemoconcentration evidenced by a raised Hb value adversely effects on infant growth. Our data may be helpful when considering the normal ranges of these blood parameters for healthy parturient women.

Radioimmunologic technique of double antibodies was used for the determination of alphafetoprotein (AFP) concentrations in blood serum samples from 223 healthy, pregnant women with single pregnancies and in amniotic fluid samples from 43 donors. The gestational age during samples collection was 10 to 25 weeks. The AFP preparation for the test was supplied by the International Agency of Cancer Research, anti-AFP antibodies produced by Behringwerke and personally produced rabbit antiglobulin antibodies. The results of the AFP determinations in the blood and amniotic fluid samples were presented in tables in form of medians. The serum AFP concentrations overranging the double medians value were met in 8.5%, overranging the triple medians - in 2.6%. Repeat determinations decreased the number of false positive results for about 50%. The results permit to issue a conclusion that the used technique is fully applicable for scan examinations in prenatal diagnosis of fetal nervous system malformations.
Full Text Available Decidual CD8+ (dCD8 T cells have been proposed to play important roles in immune protection against the invading pathogens and in tolerance toward the growing semi-allogeneic fetus during early pregnancy. However, their phenotypic and functional characteristics remain poorly defined. Here, we performed the first analysis of the transcriptional and alternative splicing (AS signatures for human first-trimester dCD8 T cells using high-throughput mRNA sequencing. Our data revealed that dCD8 T cells have distinct transcriptional and AS landscapes when compared with their autologous peripheral blood CD8+ (pCD8 T counterparts. Furthermore, human dCD8 T cells were observed to contain CD8-Treg and effector-memory T-cell subsets, and display enhanced functionality in terms of degranulation and cytokine production on a per-cell basis. Additionally, we have identified the novel splice junctions that use a high ratio of the non-canonical splicing motif GC-AG and found that AS is not a major contributor to the gene expression-level changes between paired pCD8 and dCD8 T cells. Together, our findings not only provide a comprehensive framework of the transcriptional and AS landscapes but also reveal the functional feature of human dCD8 T cells, which are of great importance in understanding the biology of these cells and the physiology of human healthy pregnancy.

We compute the commutators of the regularized quantum stress-tensor of singleton theories formulated on the boundary of a (p + 2)-dimensional anti de Sitter space (AdS p+2 ). (These are superconformal field theories on S p x S 1 ). We find that the algebra is not closed except in the case of AdS 3 . It does contain, however, the finite dimensional AdS p+2 algebra SO(p + 1,2). We also find divergent, field dependent as well as field independent Schwinger terms (i.e. the central extensions), which, however, do not lead to anomalies in the algebra of the AdS charges. We also give a simple derivation of the two-point functions for bosonic and fermionic singletons. (author). 15 refs

In visual search, an irrelevant colour singleton captures attention when the colour of the distractor changes across trials (e.g., from red to green), but not when the colour remains constant (Becker, 2007). The present study shows that intertrial changes of the distractor colour also modulate oculomotor capture: an irrelevant colour singleton distractor was only selected more frequently than the inconspicuous nontargets (1) when its features had switched (compared to the previous trial), or (2) when the distractor had been presented at the same position as the target on the previous trial. These results throw doubt on the notion that colour distractors capture attention and the eyes because of their high feature contrast, which is available at an earlier point in time than information about specific feature values. Instead, attention and eye movements are apparently controlled by a system that operates on feature-specific information, and gauges the informativity of nominally irrelevant features.

Twins constitute a valuable resource for genetic studies of asthma. However, critics argue that twins are 'special' in terms of prenatal environment and upbringing and therefore nonrepresentative. In respect to asthma a small range of studies report differential morbidity in twins compared...... with singletons. We review some of the possible explanations for these findings and conclude that results from twin studies of asthma can be extrapolated to the general population....
Full Text Available Pregnancy after the 40th week of gestation is often a great dilemma for obstetrician in diagnostic, therapeutic and in psychological terms as well. The aim of this study was to confirm the phenomenon of placental insufficiency in pregnancy after the 40th gestation week, the modality of delivery and perinatal outcome.The study comprised 3405 deliveries in a period of one year, 391 of which were terminated after the end of the 40th gestation week, including healthy pregnant women with singleton pregnancies. Control group included healthy pregnant women delivered between the 37th and 40th gestation week.The incidence of deliveries after the 40th week of gestation is 11.48%. Non-stress test was reactive in 99.65% of women in the study group. At the same time, CST (constriction– stress test was assessed as negative in 78.67% of cases. The pathological CST was found in only 1.33% of cases. Doppler ultrasound measurements showed the increased resistance in umbilical artery flow in 3% of cases. Vacuum extraction was used for 16.62%of deliveries in the study group, and 8.73% of deliveries in the control group (χ2=23.24;p<0.001. In the study group, Caesarean section was performed in 14.58% of cases, and in control group in 9.07% (χ2=11.09; p<0.001.Placental insufficiency induced by duration of pregnancy is a rear phenomenon in uncompromised pregnancy. There was no significant difference in the morbidity and mortality rates between the study and control group.

Do in vitro fertilization (IVF) multiples generate higher hospital costs than IVF singletons, from birth up to age 5? Hospital costs from birth up to age 5 were significantly higher among IVF/ICSI multiple children compared with IVF/ICSI singletons; however, when excluding the costs incurred during the birth admission period, hospital costs of multiples and singletons were comparable. Concern has risen over the long-term outcome of children born after IVF. The increased incidence of multiple births in IVF as a result of double-embryo transfer predisposes children to a poorer neonatal outcome such as preterm birth and low birthweight. As a consequence, IVF multiples require more medical care. Costs and consequences of poorer neonatal outcomes in multiples may also exist later in life. All 5497 children born from IVF in 2003-2005, whose parents received IVF or ICSI treatment in one of five participating Dutch IVF centers, served as a basis for a retrospective cohort study. Based on gestational age, birthweight, Apgar and congenital malformation, children were assigned to one of three risk strata (low-, moderate- or high-risk). To enhance the efficiency of the data collection, 816 multiples and 584 singletons were selected for 5-year follow-up based on stratified (risk) sampling. Parental informed consent was received of 322 multiples and 293 singletons. Individual-level hospital resource use data (hospitalization, outpatient visits and medical procedures) were retrieved from hospital information systems and patient charts for 302 multiples and 278 singletons. The risk of hospitalization (OR 4.9, 95% CI 3.3-7.0), outpatient visits (OR 2.6, 95% CI 1.8-3.6) and medical procedures (OR 1.7, 95% CI 1.2-2.2) was higher for multiples compared with singletons. The average hospital costs amounted to €10 018 and €2093 during the birth admission period (P IVF/ICSI multiples compared with IVF/ICSI singletons.

Non-invasive hemodynamic monitoring has the potential to be a valuable clinical tool for the screening and management of hypertensive disorders of pregnancy. The objective of this study was to validate the clinical utility of the non-invasive cardiac output monitoring (NICOM) system in pregnant women. Twenty healthy pregnant women with a singleton pregnancy at 22 to 26 weeks' gestation were enrolled in this study. Measures of heart rate, stroke volume, and cardiac output were obtained through NICOM and compared with Doppler echocardiography. NICOM significantly overestimated measures of both stroke volume and cardiac output compared with Doppler echocardiography (95 ± 4 vs. 73 ± 4 mL, P gold standard for the measurement of cardiac output in the setting of pregnancy. However, once normal values have been established, NICOM has the potential to be a useful clinical tool for monitoring maternal hemodynamics in pregnant women. Further investigation regarding the validity of NICOM is required in larger populations of healthy and hypertensive pregnant women to determine whether this device is appropriate for maternal hemodynamic assessment during pregnancy.

To develop and validate a prognostic model for prediction of spontaneous preterm birth. Prospective cohort study using data of the nationwide perinatal registry in The Netherlands. We studied 1,524,058 singleton pregnancies between 1999 and 2007. We developed a multiple logistic regression model to estimate the risk of spontaneous preterm birth based on maternal and pregnancy characteristics. We used bootstrapping techniques to internally validate our model. Discrimination (AUC), accuracy (Brier score) and calibration (calibration graphs and Hosmer-Lemeshow C-statistic) were used to assess the model's predictive performance. Our primary outcome measure was spontaneous preterm birth at model included 13 variables for predicting preterm birth. The predicted probabilities ranged from 0.01 to 0.71 (IQR 0.02-0.04). The model had an area under the receiver operator characteristic curve (AUC) of 0.63 (95% CI 0.63-0.63), the Brier score was 0.04 (95% CI 0.04-0.04) and the Hosmer Lemeshow C-statistic was significant (pvalues of predicted probability. The positive predictive value was 26% (95% CI 20-33%) for the 0.4 probability cut-off point. The model's discrimination was fair and it had modest calibration. Previous preterm birth, drug abuse and vaginal bleeding in the first half of pregnancy were the most important predictors for spontaneous preterm birth. Although not applicable in clinical practice yet, this model is a next step towards early prediction of spontaneous preterm birth that enables caregivers to start preventive therapy in women at higher risk.

To investigate gestational and postural changes in diameter and blood flow in the proximal deep leg veins during pregnancy. A longitudinal, prospective observational study. The ultrasound department of a teaching maternity hospital. Twenty-four healthy women with uncomplicated singleton pregnancies. Real-time and duplex Doppler ultrasound assessments of the vessel diameter, flow velocity and respiratory flow fluctuation in the proximal deep leg veins of women serially measured from the first trimester of pregnancy to six weeks postnatally. The effects of increasing gestation and the adoption of the left lateral position on the above parameters. An increase in vessel diameter and a fall in flow velocity with increasing gestation was observed. However, no change in venous flow variation was observed. Delivery had reverse effects. Flow velocity was slower in the left than right legs, but on adoption of the left lateral position an increase in flow velocity and venous flow variation was observed in both legs during pregnancy. These data are consistent with the observed increase in incidence and pattern of deep venous thrombosis in pregnancy and may aid interpretation of duplex Doppler ultrasound examinations for deep venous thrombosis in pregnancy. Postural changes should be part of this evaluation. The gravid uterus may not be the sole cause for postural changes in deep venous flow velocity.

Preterm prelabor rupture of membranes occurs in 3% of all pregnancies. Neonatal benefit is seen in uninfected women who do not deliver immediately after preterm prelabor rupture of membranes. The purpose of this study was to evaluate whether the administration of progestogens in singleton pregnancies prolongs pregnancy after preterm prelabor rupture of membranes. Searches were performed in MEDLINE, OVID, Scopus, EMBASE, ClinicalTrials.gov, and the Cochrane Central Register of Controlled Trials with the use of a combination of keywords and text words related to "progesterone," "progestogen," "prematurity," and "preterm premature rupture of membranes" from the inception of the databases until January 2018. We included all randomized controlled trials of singleton gestations after preterm prelabor rupture of membranes that were randomized to either progestogens or control (either placebo or no treatment). Exclusion criteria were trials that included women who had contraindications to expectant management after preterm prelabor rupture of membranes (ie, chorioamnionitis, severe preeclampsia, and nonreassuring fetal status) and trials on multiple gestations. We planned to include all progestogens, including but not limited to 17-α hydroxyprogesterone caproate, and natural progesterone. The primary outcome was latency from randomization to delivery. Metaanalysis was performed with the use of the random effects model of DerSimonian and Laird to produce relative risk with 95% confidence interval. Analysis was performed for each mode of progestogen administration separately. Six randomized controlled trials (n=545 participants) were included. Four of the included trials assessed the efficacy of 17-α hydroxyprogesterone caproate; 1 trial assessed rectal progestogen, and 1 trial had 3 arms that compared 17-α hydroxyprogesterone caproate, rectal progestogen, and placebo. The mean gestational age at time randomization was 26.9 weeks in the 17-α hydroxyprogesterone caproate

BACKGROUND Hematopoietic growth factors (HGFs) are mostly used as supportive measures to reduce infectious complications associated with neutropenia. Over the past decade, the use of HGFs became a common method for mobilizing human CD34+ stem cells, either for autologous or allogeneic transplantation. However, since their introduction the long-term safety of the procedure has become a major focus of discussion and research. Most information refers to healthy normal donors and data concerning pregnant and lactating women are scarce. The clinical question, which is the core of this review, is whether stem cell donation, preceded by administration of granulocyte-colony stimulating factor (G-CSF) for mobilization, is a safe procedure for pregnant donors. METHODS Literature searches were performed in Pubmed for English language articles published before the end of May 2012, focusing on G-CSF administration during pregnancy, lactation and hematopoietic stem cell donation. Searches included animal and human studies. RESULTS Data from animals (n = 15 studies) and women (n = 46 studies) indicate that G-CSF crosses the placenta, stimulates fetal granulopoiesis, improves neonatal survival mostly for very immature infants, promotes trophoblast growth and placental metabolism and has an anti-abortive role. Granulocyte macrophage-CSF is a key cytokine in the maternal immune tolerance towards the implanted embryo and exerts protective long-term programming effects to preimplantation embryos. The available data suggest that probably CSFs should not be administered during the time of most active organogenesis (first trimester), except perhaps for the first week during which implantation takes place. Provided CSF is administered during the second and third trimesters, it appears to be safe, and pregnant women receiving the CSF treatment can become hematopoietic stem cell donors. There are also risks related to the anesthesia, which is required for the bone marrow aspiration. During

To analyze the associations between pregnancy-related anxiety and the prevalence of subthreshold autism trait (SAT) in preschool children. Baseline data came from the Ma'anshan Birth Cohort Study, a part of the China-Anhui Birth Cohort Study (C-ABCS). All the participants were enrolled among pregnant women who received prenatal health care in 4 municipal medical centers during Oct. 2008 to Oct. 2010. A total of 5 084 pregnant women were recruited at the beginning and 4 669 singleton live births were included until childbirth. The situation about pregnancy-specific anxiety during trimester and third trimester of women were evaluated by Pregnancy-specific Anxiety Questionnaire (PAQ). Between April 2014 and April 2015, the cohort was followed up again, and the Clancy Autism Behavior Scale (CABRS) filled out by parents was used for telling the SAT children from the healthy children among 3 663 preschool children. Univariate and binary regression model was used to estimate associations between the pregnancy-related anxiety during trimester and third trimester and the subthreshold autism trait in children. During the pregnancy, the detected rates of women with pregnancy-specific anxiety in trimester and the third trimester were 25.5%(935/3 663), 13.9%(501/3 592) respectively, and the detected rate of maternal pregnancy-specific anxiety in both periods was 7.7%(278/3 592). There were 290 positive children with SAT and the detection rate was 7.9%. After controlling possible confounding factors including children's genders, place of residence, supplement folic acid during pregnancy, preterm birth, exposure to second-hand smoke during pregnancy, the father (mother) cultural levels, the father (mother) nature of work and family income, the results of multinomial logistic regression analysis showed that maternal pregnancy-specific anxiety in trimester was the risk factor for SAT in preschool children (OR=1.51, 95% CI: 1.11-2.04), and there was no association between maternal

Routine exercise should be recommended to healthy pregnant women after consultation with an obstetric provider. Even pregnant women who have not been exercising regularly can gradually increase their exercise during pregnancy. Regular exercise during pregnancy promotes overall wellness and helps maintain appropriate gestational weight gain and appropriate fetal weight gain. Exercise in pregnancy may also reduce hypertensive disorders of pregnancy and gestational diabetes, and may be associated with shorter first stage of labor and decreased risk for cesarean section. Exercise in pregnancy is safe for pregnant women and their fetuses and can have multiple health benefits. Copyright © 2017 Elsevier Inc. All rights reserved.

The incidence of twin gestation has increased markedly over the past decades, mostly because of increased use of assisted reproductive technologies. Twin pregnancies are at increased risk of preterm delivery (i.e. birth before 37 weeks of gestation). Multiple gestations therefore account for 2...... sequelae such as abnormal neurophysiological development in early childhood and underachievement in school. Several treatment modalities have been proposed in singleton high-risk pregnancies. The mechanism of initiating labour may, however, be different in singleton and twin gestations. Therefore......, it is mandatory to evaluate the proposed treatments in randomised trials of multiple gestations. In this chapter, we describe the results of trials to prevent preterm delivery in twin pregnancies....

To explore the effect of hospital's characteristics in the proportion of obstetric interventions (OI) performed in singleton fullterm births (SFTB) in Catalonia (2010-2014), while incentives were employed to reduce C-sections. Data about SFTB assisted at 42 public hospitals were extracted from the dataset of hospital discharges. Hospitals were classified according to the level of complexity, the volume of births attended, and the adoption of a non-medicalized delivery (NMD) strategy. The annual average change in the percentage for OI was calculated based on Poisson regression models. The rate of OI (35% of all SFTB) including C-sections (20.6%) remained stable through the period. Hospitals attending less complex cases had a lower average of OI, while hospitals attending lower volumes had the highest average. Higher levels of complexity increased the use of C-sections (+4% yearly) and forceps (+16%). The adoption of the NMD strategy decreased the rate of C-sections. The proportion of OI, including C-sections, remained stable in spite of public incentives to reduce them. The adoption of the NMD strategy could help in decreasing the rate of OI. To reduce the OI rate, new strategies should be launched as the development of low-risk pregnancies units, alignment of incentives and hospital payment, increased value of incentives and encouragement of a cultural shift towards non-medicalized births.

Sub-Saharan Africa has the world's highest under-5 and neonatal mortality rates as well as the highest naturally occurring twin rates. Twin pregnancies carry high risk for children and mothers. Under-5 mortality has declined in sub-Saharan Africa over the last decades. It is unknown whether twins have shared in this reduction. We pooled data from 90 Demographic and Health Surveys for 30 sub-Saharan Africa countries on births reported between 1995 and 2014. We used information on 1 685 110 singleton and 56 597 twin livebirths to compute trends in mortality rates for singletons and twins. We examined whether the twin-singleton rate ratio can be attributed to biological, socioeconomic, care-related factors, or birth size, and estimated the mortality burden among sub-Saharan African twins. Under-5 mortality among twins has declined from 327·7 (95% CI 312·0-343·5) per 1000 livebirths in 1995-2001 to 213·0 (196·7-229·2) in 2009-14. This decline of 35·0% was much less steep than the 50·6% reduction among singletons (from 128·6 [95% CI 126·4-130·8] per 1000 livebirths in 1995-2001 to 63·5 [61·6-65·3] in 2009-14). Twins account for an increasing share of under-5 deaths in sub-Saharan Africa: currently 10·7% of under-5 mortality and 15·1% of neonatal mortality. We estimated that about 315 000 twins (uncertainty interval 289 000-343 000) die in sub-Saharan African each year. Excess twin mortality cannot be explained by common risk factors for under-5 mortality, including birthweight. The difference with singletons was especially stark for neonatal mortality (rate ratio 5·0, 95% CI 4·5-5·6). 51·7% of women pregnant with twins reported receiving medical assistance at birth. The fate of twins in sub-Saharan Africa is lagging behind that of singletons. An alarming one-fifth of twins in the region dies before age 5 years, three times the mortality rate among singletons. Twins account for a substantial and growing share of under-5 and neonatal

We analyse the spectrum of the eleven dimensional supermembrane quantized in AdS 4 xS 7 background. The classical membrane lives at the boundary of AdS 4 which is S 2 xS 1 , and has OSp(8,4) symmetry. We find that the spectrum contains, in addition to the N=8 supersymmetric (massive) singletons (which may possibly be the ultimate preons), also massless states of all higher integer and half-integer spin. These states fill the irreducible representations of OSp(8,4) with highest spin s max =2,4,6,... The s max =2 multiplet corresponds to the states of the de Wit-Nicolai's N=8 gauged supergravity in four dimensions. (author). 24 refs

DOI: 10.1111\\/j.1471-0528.2011.03245.x. Objective Obstetric cholestasis (OC) is a liver disorder characterised by pruritus and elevated serum bile acids (SBA) that affects one in 200 pregnant women. It is associated with adverse perinatal outcomes such as premature delivery and stillbirth. Mild OC is defined as SBA levels of 10-39 mumol\\/l, and severe OC is defined by levels >40 mumol\\/l. SBA levels in normal pregnancy have not been investigated. We aimed to establish reference values for SBA in healthy pregnant women across different trimesters of pregnancy. Design Cross-sectional analysis of SBA levels. Setting A large tertiary referral university teaching maternity hospital. Population Healthy pregnant women with a singleton pregnancy and a body mass index (BMI) < 40, excluding women with significant alcohol intake, history of liver disease, prior cholecystectomy and OC. Methods Cross-sectional analysis of SBA levels at 12, 20, 28 and 36 weeks of gestation, and on days 1-3 postpartum. Main outcome measures SBA levels in mumol\\/l. Results A total of 219 women attending for antenatal care were recruited, and SBA levels were assayed at 12, 20, 28 and 36 weeks of gestation, and up to 72 hours postpartum (n = 44-49 cases at each stage). The majority were white European women, with a median age of 30 years (range 17-46 years) and median BMI of 25 (range 18-38). Values of SBA ranged from 0.3 to 9.8 mumol\\/l in 216 women, with only three measurements outside this range. There were no significant changes throughout pregnancy. Conclusions SBA values in uncomplicated pregnancies are consistent, regardless of gestation, and are not elevated in pregnancy. The current reference values for the diagnosis of OC appear to be appropriate.

We present a case of a 29-year-old woman, with a history of ectopic pregnancy, which required left salpingectomy, and with a tortuous and impermeable right fallopian tube, compatible with hydrosalpinx. As hydrosalpinx itself can compromise a future pregnancy, treatment with Essure was proposed before passing to medically assisted procreation techniques. Five months after placement of Essure in the right fallopian tube, an in vitro fertilisation cycle was successfully completed and the woman had a singleton pregnancy and vaginal delivery without intercurrences.

Certain perfluoroalkyl and polyfluoroalkyl substances (PFAS) are widespread, persistent environmental contaminants. Prenatal PFAS exposure has been associated with lower birth weight; however, impacts on body composition and factors responsible for this association are unknown. We aimed to estimate associations between maternal PFAS concentrations and offspring weight and adiposity at birth, and secondarily to estimate associations between PFAS concentrations and maternal glucose and lipids, and to evaluate the potential for these nutrients to mediate associations between PFAS and neonatal outcomes. Within the Healthy Start prospective cohort, concentrations of 11 PFAS, fasting glucose, and lipids were measured in maternal mid-pregnancy serum (n=628). Infant body composition was measured using air displacement plethysmography. Associations between PFAS and birth weight and adiposity, and between PFAS and maternal glucose and lipids, were estimated via linear regression. Associations were decomposed into direct and indirect effects. Five PFAS were detectable in >50% of participants. Maternal perfluorooctanoate (PFOA) and perfluorononanoate (PFNA) concentrations were inversely associated with birth weight. Adiposity at birth was approximately 10% lower in the highest categories of PFOA, PFNA, and perfluorohexane sulfonate (PFHxS) compared to the lowest categories. PFOA, PFNA, perfluorodecanoate (PFDeA), and PFHxS were inversely associated with maternal glucose. Up to 11.6% of the effect of PFAS on neonatal adiposity was mediated by maternal glucose concentrations. Perfluorooctane sulfonate (PFOS) was not significantly associated with any outcomes studied. Follow-up of offspring will determine the potential long-term consequences of lower weight and adiposity at birth associated with prenatal PFAS exposure. https://doi.org/10.1289/EHP641.

Twin pregnancies are at increased risk for adverse outcomes and are associated with greater gestational weight gain compared to singleton pregnancies. Studies that disentangle the relationship between gestational duration, weight gain and adverse outcomes are needed to inform weight gain guidelines. We created charts of the mean, standard deviation and select percentiles of maternal weight gain-for-gestational age in twin pregnancies and compared them to singleton curves. We abstracted serial prenatal weight measurements of women delivering uncomplicated twin pregnancies at Magee-Womens Hospital (Pittsburgh, PA, 1998-2013) and merged them with the hospital's perinatal database. Hierarchical linear regression was used to express pregnancy weight gain as a smoothed function of gestational age according to pre-pregnancy BMI category. Charts of week- and day-specific values for the mean, standard deviation, and percentiles of maternal weight gain were created. Prenatal weight measurements (median: 11 [interquartile range: 9, 13] per woman) were available for 1109 women (573 normal weight, 287 overweight, and 249 obese). The slope of weight gain was most pronounced in normal weight women and flattened with increasing pre-pregnancy BMI (e.g. 50th percentiles of 6.8, 5.7, and 3.6 kg at 20 weeks and 19.8, 18.1, and 14.4 at 37 weeks in normal weight, overweight, and obese women, respectively). Weight gain patterns in twins diverged from singletons after 17-19 weeks. Our charts provide a tool for the classification of maternal weight gain in twin pregnancies. Future work is needed to identify the range of weight gain associated with optimal pregnancy health outcomes. © 2018 John Wiley & Sons Ltd.

The language development of twins tends to lag behind in comparison to that of singletons. The purpose of this study was to compare expressive and receptive language skills of 3- to 12-year-old twins with singletons. Secondly, correlations between language differences between twins and singletons and age were investigated. Twenty-four twins with a mean age of 5.1 years participated in the study. The control group consisted of 24 singletons who were matched for gender and age. Language development was investigated using the Clinical Evaluation of Language Fundamentals. Twins scored significantly lower for expressive and receptive language skills compared to singletons. Even when excluding preterm-born children, twins still scored significantly lower for expressive language skills. There was no correlation between age and language differences between twins and their matched singletons. Twins score lower for expressive and receptive language skills compared to singletons, and preterm birth cannot be regarded as the main cause for the language delay. The language delay in twins is rather mild but does not seem to decrease with increasing age. © 2016 S. Karger AG, Basel.

Introduction It has been established that underweight women with low gestational weight gain (GWG) are at a higher risk of having Small for Gestational Age (SGA) newborns. However, the association remains poorly studied in Middle Eastern societies exhibiting different ethnic groups, genetic predisposing factors along with differences in nutritional food intake during pregnancy. The aim of this study is to assess the risk of having a SGA newborn among underweight and normal weight BMI women while studying the role of GWG in this association. Methods This is a retrospective cross-sectional study of 62,351 singleton pregnancies from the National Collaborative Perinatal Neonatal Network between 2001 and 2009 from 27 hospitals across Lebanon. Women who had underweight and normal pre-pregnancy BMI were included. Results A total of 8.6% newborns were SGA and 6.6% of women were underweight. Among women with normal and underweight pre-pregnancy BMI, 8.6 and 12.4% had SGA births respectively. Overall, the adjusted OR of having SGA newborns was significantly higher among underweight women (OR = 1.448; 95%CI = 1.287-1.630) compared to normal pre-pregnancy BMI. Below normal weight gain significantly increased the odds of SGA for both normal and underweight pre-pregnancy BMI women, with adjusted ORs of 1.535 (95% CI = 1.418-1.661) and 1.970 (95%CI = 1.515-2.560) respectively. Discussion Higher risks of SGA newborns in underweight and normal BMI women with low GWG were observed. In addition, normal weight gain couldn't protect underweight women of having risk for SGA newborns. Hence, all pregnant women should be encouraged to maintain healthy BMI before pregnancy and attain adequate GWG.

Background Despite documented health benefits for mother and baby, physical activity (PA)-level tends to decline in pregnancy. Overweight/obese and physically inactive women are two selected groups at increased risk of pregnancy complications. Thus, efficient strategies to maintain or increase PA-level in pregnancy and the postpartum period, especially among these women, are warranted. This secondary analysis examined the effect of a prenatal lifestyle-intervention on PA-level in late pregnancy and the first year postpartum, with subanalysis on initially physically active versus inactive and normal-weight versus overweight/obese women. Method The Norwegian Fit for Delivery (NFFD) randomized controlled trial included healthy primiparous women with singleton pregnancies and body mass index (BMI) ≥19 kg/m2 assigned to an intervention group, n = 303 (twice weekly group-exercises and dietary counseling) or a control group, n = 303 (standard prenatal care). The International Physical Activity Questionnaire short-form was used to assess PA-levels at inclusion (mean gestational week (GW) 16), GW 36, and six and 12 months postpartum. Results At GW 36, a positive intervention-effect with a significant between-group difference in total PA-level compared to time of inclusion was found for the total group (530 MET-min/week, p = 0.001) and the subgroups of normal-weight (533 MET-min/week, p = 0.003) and initially active women (717 MET-min/week, ppregnancy among women entering pregnancy normal-weight or physically active, thereby preventing the downward trend typically seen during pregnancy. Intervention-effect among overweight/obese and physically inactive women was, however, dependent on exercise-adherence. Long-term intervention-effect was not observed in the postpartum period.

Recent studies comparing cognitive abilities between contemporary twins and singletons in developed countries have suggested that twin deficits in cognitive abilities no longer exist. We examined cognitive abilities in a sample of twins and singletons born recently in Nigeria to determine whether recent findings can be replicated in developing countries. Our sample consisted of 413 pairs of twins and 280 singletons collected from over 45 public schools in Abuja and its neighboring states in Nigeria. The ages of twins and singletons ranged from 9 to 20 years with a mean (SD) of 14.6 years (2.2 years) for twins and 16.1 years (1.8 years) for singletons. Zygosity of the same-sex twins was determined by analysis of 16 deoxyribonucleic acid markers. We asked participants to complete a questionnaire booklet that included Standard Progressive Matrices-Plus Version (SPM+), Mill-Hill Vocabulary Scale (MHV), Family Assets Questionnaire, and demographic questions. The data were corrected for sex and age and then analyzed using maximum likelihood model-fitting analysis. Although twins and singletons were comparable in family social class indicators, singletons did better than twins across all the tests (d = 0.10 to 0.35). The average of d for SPM+ total [0.32; equivalent to 4.8 Intelligence Quotient (IQ) points] and d for MHV (0.24; equivalent to 3.6 IQ points) was 0.28 (equivalent to 4.2 IQ points), similar to the twin-singleton gap found in old cohorts in developed countries. We speculate that malnutrition, poor health, and educational systems in Nigeria may explain the persistence of twin deficits in cognitive abilities found in our sample.

The present study was aimed to test the association between asymptomatic bacteriuria during pregnancy, among patients in whom antibiotic treatment was recommended, and perinatal outcome. Our study was also designed to characterize common bacteria and risk factors associated with asymptomatic bacteriuria during pregnancy. A retrospective population-based study comparing all singleton pregnancies of women with and asymptomatic bacteriuria was conducted. Patients with urinary tract infection were excluded from the analysis. Multiple logistic regression model was used to control for confounders. Out of 199,093 deliveries, 2.5% (n = 4890) were in patients with asymptomatic bacteriuria. E. coli was the most common pathogen associated with asymptomatic bacteriuria, representing 78.6% of the cultures with specified growth. Patients with asymptomatic bacteriuria were more likely to deliver preterm (PTD, 13.3%vs. 7.6%, odd ratio (OR) = 1.9, 95% confidence interval CI 1.7-2.0; P Asymptomatic bacteriuria was independently associated with PTD (adjusted OR = 1.6; 95% CI 1.5-1.7; P treatments, hypertensive disorders, recurrent abortions, diabetes mellitus, intrauterine growth restriction, polyhydramnion and oligohydramnion, premature rupture of membranes and labour induction, in a multivariable analysis with backwards elimination. Perinatal mortality rates (1.5%vs. 1.4%; P = 0.707) as well as low 5 min Apgar scores (0.8%vs. 0.6%; P = 0.065) were comparable between the groups. Asymptomatic bacteriuria is an independent risk factor for preterm delivery.
Full Text Available The interpretation of identity compatibility effects associated with irrelevant items outside the nominal focus of attention has fueled much of the debate over early versus late selection and perceptual load theory. However, compatibility effects have also played a role in the debate over the extent to which the involuntary allocation of spatial attention (i.e., attentional capture is completely stimulus-driven or whether it is contingent on top-down control settings. For example, in the context of the additional singleton paradigm, irrelevant color singletons have been found to produce not only an overall cost in search performance but also significant compatibility effects. This combination of search costs and compatibility effects has been taken as evidence that spatial attention is indeed allocated in a bottom-up fashion to the salient but irrelevant singletons. However, it is possible that compatibility effects in the additional singleton paradigm reflect parallel processing of identity associated with low perceptual load rather than an involuntary shift of spatial attention. In the present experiments, manipulations of load were incorporated into the traditional additional singleton paradigm. Under low load conditions, both search costs and compatibility effects were obtained, replicating previous studies. Under high load conditions, search costs were still present, but compatibility effects were eliminated. This dissociation suggests that the costs associated with irrelevant singletons may reflect filtering processes rather than the allocation of spatial attention.

Increased utilization of in vitro fertilization (IVF) to treat infertility has resulted in a growing twin birthrate. Despite early childhood risks, twins have fewer psychosocial problems in middle childhood than singleton children. This study proposes that parents' conformity expectations for children have differential effects on parent-child relationships for twin and singleton children, which indirectly explains twins' more optimum psychosocial adjustment. Parental conformity expectations, parent-child relationship satisfaction, and children's emotional, behavioral, and attention problems were assessed in a sample of 288 6- to 12-year-old IVF-conceived twins and singletons. Overall, parents of twins had higher expectations for child conformity to parent rules than singleton parents. Path models demonstrate that twin status and parental expectations for child conformity interact to influence parent-child relationships, and this interaction indirectly accounted for differences in twins' and singletons' psychosocial adjustment. Findings suggest parenting constructs have differential influences on the association between twin status and parent-child relationships. Parenting research, predominantly conducted with singletons, should be reexamined before applying existing research to twin children and their families. (c) 2015 APA, all rights reserved).

Full Text Available Background. In conditions with appropriate iodine intake, thyroid gland adapts to changes during pregnancy without any consequences. Fetal need for thyroid hormones in the first trimester is directly connected with transplacental transport of thyroid hormones. Fetal synthesis of thyroid hormones depends on availability of iodine in the feto-placental unit. Hypo- and hyperthyroidism during pregnancy are risk factors for pregnant woman and for normal development of fetus and child.Conclusions. Pregnant women with appropriately treated thyroid diseases have the same outcome of pregnancy as healthy women, and neuroendocrinological development of children is not impaired. If the disease is unrecognized or untreated, complications of pregnancy and delivery occur more frequently. Therefore, timely recognition and treatment of the diseases with appropriate drugs during pregnancy and, also, after delivery is very important.

Objective: To analyze the status of gestational weight gain (GWG) among Chinese mothers who gave singleton and full-term births, and to look at optimal GWG ranges. Methods: In 2013, using the multi-stage stratified and population proportional cluster sampling method, we investigated 8 323 mother-child pairs at their 0-24 months postpartum from 55 counties (cities/districts) of 30 provinces (except Tibet) in mainland China. Questionnaire was used to collect data on body weight before pregnancy and delivery, diseases during gestation, hemorrhage or not at postpartum, child birth weight and length, and other information about pregnant outcomes. We measured mother's body weight and height, and child's body weight and length. Based on 'Chinese Adult Body Weight Standard', we divided mothers into four groups according to their body weight before pregnancy: low weight (BMImothers and children, and according to P25-P75 of GWG among mothers who had good pregnant outcomes and good anthropometry, and whose children had good anthropometry. The status of GWG was assessed by the new optimal ranges. Results: P50 (P25-P75) of GWG among the 8 323 mothers was 15.0 (10.0-19.0) kg. According to the proposed optimal GWG ranges of IOM, the proportions of inadequate, optimal and excessive GWG accounted for 27.2% (2 263 mothers), 36.2% (3 016 mothers) and 36.6% (3 044 mothers). The optimal GWG ranges for low weight, normal weight, overweight and obesity were 11.5-18.0, 10.0-15.0, 8.0-14.0 and 5.0-11.5 kg. Based on these optimal GWG ranges established in this study, the rates of inadequate, optimal and excessive GWG were 15.7% (1 303 mothers), 45.0% (3 744 mothers) and 39.3% (3 276 mothers), and these rates were significantly different from that defined by the IOM standards (χ2=345.36, Pmothers is 15.0 kg, which is at a relatively higher level. This study suggests the optimal GWG ranges for Chinese women who give singleton and full-term babies, which appears lower than IOM's.

OBJECTIVE: To clarify the obstetric consequences in a second pregnancy after a first singleton pregnancy complicated by spontaneous preterm delivery or preeclampsia and stratified by the variation in fetal growth. METHODS: In a registry-based cohort study, we identified women having a first...... pregnancies. RESULTS: Compared with a spontaneous first delivery at term, a delivery between 32 and 36 weeks of gestation increased the risk of preterm delivery in the second pregnancy from 2.7% to 14.7% (odds ratio [OR] 6.12, 95% confidence interval [CI] 5.84-6.42) and the risk of preeclampsia from 1.1% to 1.......8% (OR 1.60, 95% CI 1.41-1.81); a delivery before 28 weeks increased the risk of a second preterm delivery to 26.0% (OR 13.1, 95% CI 10.8-15.9) and a second pregnancy with preeclampsia to 3.2% (OR 2.96, 95% CI 1.80-4.88). A first delivery in preeclamptic women between 32 and 36 weeks, compared...

Most studies on birth settings investigate the association between planned place of birth at the start of labor and birth outcomes and intervention rates. To optimize maternity care it also is important to pay attention to the entire process of pregnancy and childbirth. This study explores the association between the initial preferred place of birth and model of care, and the course of pregnancy and labor in low-risk nulliparous women in the Netherlands. As part of a Dutch prospective cohort study (2007-2011), we compared medical indications during pregnancy and birth outcomes of 576 women who initially preferred a home birth (n = 226), a midwife-led hospital birth (n = 168) or an obstetrician-led hospital birth (n = 182). Data were obtained by a questionnaire before 20 weeks of gestation and by medical records. Analyses were performed according to the initial preferred place of birth. Low-risk nulliparous women who preferred a home birth with midwife-led care were less likely to be diagnosed with a medical indication during pregnancy compared to women who preferred a birth with obstetrician-led care (OR 0.41 95% CI 0.25-0.66). Preferring a birth with midwife-led care - both at home and in hospital - was associated with lower odds of induced labor (OR 0.51 95% CI 0.28-0.95 respectively OR 0.42 95% CI 0.21-0.85) and epidural analgesia (OR 0.32 95% CI 0.18-0.56 respectively OR 0.34 95% CI 0.19-0.62) compared to preferring a birth with obstetrician-led care. In addition, women who preferred a home birth were less likely to experience augmentation of labor (OR 0.54 95% CI 0.32-0.93) and narcotic analgesia (OR 0.41 95% CI 0.21-0.79) compared to women who preferred a birth with obstetrician-led care. We observed no significant association between preferred place of birth and mode of birth. Nulliparous women who initially preferred a home birth were less likely to be diagnosed with a medical indication during pregnancy. Women who initially preferred a birth

Overweight, obesity and excess gestational weight gain (GWG) are associated with negative health outcomes for mother and child in pregnancy and across the life course. Interventions promoting GWG within guidelines report mixed results. Most are time and cost intensive, which limits scalability. Mobile technologies (mHealth) offer low cost, ready access and individually-tailored support. We aim to test the feasibility of an mHealth intervention promoting healthy nutrition, physical activity and GWG in women who begin pregnancy overweight or obese. txt4two is a parallel randomised control trial pilot recruiting women with a singleton, live gestation between 10(+0) and 17(+6) weeks at the first hospital antenatal clinic visit. Inclusion criteria are pre-pregnancy BMI > 25 kg/m(2) and mobile phone ownership. One hundred consenting women will be randomised to intervention or control groups at a 1:1 ratio. All participants will receive standard antenatal care. In addition, the txt4two intervention will be delivered from baseline to 36 weeks gestation and consists of a tailored suite of theoretically-grounded, evidence-based intervention strategies focusing on healthy nutrition, physical activity and GWG. This includes: mobile phone interactive text messages promoting positive health behaviours, goal setting and self-monitoring; video messages; an information website; and a private moderated Facebook® chat forum. The primary outcome is the feasibility of the intervention. Secondary outcomes include GWG and participants' knowledge and behaviour regarding diet and physical activity during pregnancy. Findings will inform the development of larger-scale mHealth programmes to improve the delivery of healthy pregnancy nutrition, physical activity and GWG, that could be widely translated and disseminated.

Full Text Available Visual search is easier after observing some distractors in advance; it is as if the previewed distractors were excluded from the search. This effect is referred to as the preview benefit, and a memory template that visually marks the old locations of the distractors is thought to help in prioritizing the locations of newly presented items. One remaining question is whether the presence of a conspicuous item during the sequential shift of attention within the new items reduces this preview benefit. To address this issue, we combined the above preview search and a conventional visual search paradigm using a singleton distractor and examined whether the search performance was affected by the presence of the singleton. The results showed that the slope of reaction time as a function of set size became steeper in the presence of a singleton, indicating that the singleton distractor reduced the preview benefit. Furthermore, this degradation effect was positively correlated with the degree of conventional attentional capture to a singleton measured in a separate experiment with simultaneous search. These findings suggest that the mechanism of visual marking shares common attentional resources with the search process.

To document the prevalence of cannabis use in a large sample of British women studied during pregnancy, to determine the association between cannabis use and social and lifestyle factors and assess any independent effects on pregnancy outcome. Self-completed questionnaire on use of cannabis before and during pregnancy. Over 12,000 women expecting singletons at 18 to 20 weeks of gestation who were enrolled in the Avon Longitudinal Study of Pregnancy and Childhood. Any association with the use of cannabis before and during pregnancy with pregnancy outcome was examined, taking into account potentially confounding factors including maternal social background and other substance use during pregnancy. Late fetal and perinatal death, special care admission of the newborn infant, birthweight, birth length and head circumference. Five percent of mothers reported smoking cannabis before and/or during pregnancy; they were younger, of lower parity, better educated and more likely to use alcohol, cigarettes, coffee, tea and hard drugs. Cannabis use during pregnancy was unrelated to risk of perinatal death or need for special care, but, the babies of women who used cannabis at least once per week before and throughout pregnancy were 216 g lighter than those of non-users, had significantly shorter birth lengths and smaller head circumferences. After adjustment for confounding factors, the association between cannabis use and birthweight failed to be statistically significant (P = 0.056) and was clearly non-linear: the adjusted mean birthweights for babies of women using cannabis at least once per week before and throughout pregnancy were 90 g lighter than the offspring of other women. No significant adjusted effects were seen for birth length and head circumference. The results of this study suggest that the use of cannabis during pregnancy was not associated with increased risk of perinatal mortality or morbidity in this sample. However, frequent and regular use of cannabis

Increased medically assisted reproduction (MAR) use to treat infertility has resulted in a growing twin birth rate. Little is known about parent-child relationships for twin relative to singleton children in middle childhood. This study fills this gap by examining parent-child relationships in 57 families with eighty 6- to 12-year-old MAR twin and singleton children using observational data (warm and supportive communication, control, and hostility). Nested ANCOVAs indicate that while mothers exhibit similar interactional behaviors toward twins and singletons, fathers have less optimum behaviors toward twins relative to singletons. Twins displayed less engaged behavior with mothers and fathers relative to singletons. Given the vitality of parent-child relationships for family and child adjustment, future studies should examine determinants and outcomes of twin-singleton relationship differences to bolster twins' and their families' functioning. © 2016 Family Process Institute.

Over the past decade, demand for fertility treatments has increased as a result of delaying time to first pregnancy and growing awareness and acceptance of available treatment options. Despite increasing demand, health authorities often view infertility as a low health priority and consequently limit access to treatments by rationing and limiting funds. To assess the long-term economic benefits attributed to in vitro fertilization (IVF)-conceived children, we developed a health investment model to evaluate whether state-funded IVF programmes in the UK represent sound fiscal policies. Based on the average investment cost to conceive an IVF singleton, we describe the present value of net taxes derived from gross taxes paid minus direct government transfers received (e.g. education, health, pension) over the lifetime of the child. To establish the present value of investing in IVF, we have discounted all costs from benefits (i.e. lifetime taxes paid) using UK Treasury department rates based on a singleton delivery with similar characteristics for education, earnings, health and life expectancy to a naturally conceived child. The lifetime discounted value of net taxes from an IVF-conceived child with mother aged 35 is pound 109,939 compared with pound 122,127 for a naturally conceived child. The lifetime undiscounted net tax contribution for the IVF-conceived child and naturally conceived child are pound 603,000 and pound 616,000, respectively. An investment of pound 12,931 to achieve an IVF singleton is actually worth 8.5-times this amount to the UK Treasury in discounted future tax revenue. The analysis underscores that costs to the health sector are actually investments when a broader government perspective is considered over a longer period of time.

BACKGROUND: Hall (Embryologic development and monozygotic twinning. Acta Geneticae Medicae et Gemellologiae, Vol. 45, 1996, pp. 53-57) hypothesized that chromosomal aberrations can lead to monozygotic (MZ) twinning. However, twinning and chromosomal aberrations increase prenatal mortality and could...... reduce the prevalence of chromosomal aberrations in live-born twins. We compared prevalence proportion ratios (PPR) of chromosomal aberrations and trisomy 21 (T21) in live-born twins versus singletons born in Denmark during 1968-2009. METHODS: We linked the Danish Twin Registry and a 5% random sample...... of all singletons to the Danish Cytogenetic Central Register and calculated PPR adjusted for maternal age for MZ, dizygotic (DZ), and all twins versus singletons. Zygosity was based on questionnaires or genetic markers. RESULTS: No overall difference in risk of chromosomal aberrations or T21 in twins...

compare rates of marriage and divorce in a sample of 35,975 twins and 81,803 singletons born 1940-1964. Cox-regressions are used in order to control for potential confounders. We find that compared with singletons twins have significantly lower marriage rates: (males: 15-19 years: Hazard Ratio (HR) = 0...... twins compared with singletons (HR=0.87, 95%CI: 0.83-0.90). These differences offset each other, thus 57% of both populations remain in their first marriage until censoring. The interpretation may be that since twins have a partner from birth, they do not have the same need for marriage as singletons...

Objective. To establish the percentile charts of birth weights for gestational age and sex within the Cameroonian population. Methods. A review of medical records of infants born between January 2007 and December 2011 at the maternities of two hospitals in Cameroon, Central Africa. Multiple pregnancies, births of HIV infected women, stillbirths, and births with major fetal malformations were excluded. The smooth curves of birth weight for gestational age and sex were created using the Gamlss package under R.3.0.1 software. Results. The birth weights of 12837 live birth singleton infants born to HIV negative women between 28 and 42 weeks of gestation were analyzed to construct the birth weight curves for gestational age and sex. The smoothed percentile curves of birth weights for gestational age and sex of Cameroonian infants have demonstrated an increasing slope until 40 weeks and then a plateau. There was a varied difference of distribution in birth weights for gestational age between Cameroonian, Botswanan, American, and French infants. Conclusion. We established the reference curves of birth weights for gestational age and sex for Cameroonians. The difference in birth weight curves noted between Cameroonian, Botswanan, American, and French infants suggests the importance of establishing the regional birth weight norms.

The weight of the placenta is a crude but useful proxy for its function in vivo. Accordingly extremes of placental weight are associated with adverse pregnancy outcomes while even normal variations in placental size may impact lifelong health. Centile charts of placental weight for gestational age and gender are used to identify placental weight extremes but none report the effect of parity. Thus the objective was to produce gender and gestational age specific centile charts for placental weight in nulliparous and multiparous women. Data was extracted from the Aberdeen Maternity and Neonatal Databank for all women delivering singleton babies in Aberdeen city and district after 24 weeks gestation. Gestational age specific centile charts for placental weight by gender and parity grouping (n = 88,649 deliveries over a 30 year period) were constructed using the LMS method after exclusion of outliers (0.63% of deliveries meeting study inclusion criteria). Tables and figures are presented for placental weight centiles according to gestational age, gender and parity grouping. Tables are additionally presented for the birth weight to placental weight ratio by gender. Placental weight and the fetal:placental weight ratio were higher in male versus female deliveries. Placental weight was greater in multiparous compared with nulliparous women. We present strong evidence that both gender and parity grouping influence placental weight centiles. The differences at any given gestational age are small and the effects of parity are greater overall than those of gender. In contrast the birth weight to placental weight ratio differs by gender only. These UK population specific centile charts may be useful in studies investigating the role of the placenta in mediating pregnancy outcome and lifelong health. Copyright © 2012 Elsevier Ltd.

To establish reference values for flow-mediated dilatation (FMD) and brachial artery diameter (BAD) in pregnancy and to provide insight into the physiological and pathological course of endothelial adaptation throughout human singleton pregnancy. A meta-analysis was performed following a systematic review of current literature on FMD, as a derivative for endothelial function, and BAD, throughout uncomplicated and complicated pregnancy. PubMed (NCBI) and EMBASE (Ovid) electronic databases were used for the literature search, which was performed from inception to 9 June 2016. To allow judgment of changes in comparison with the non-pregnant state, studies were required to report both non-pregnant mean reference of FMD (matched control group, prepregnancy or postpartum measurement) and mean FMD at a predetermined and reported gestational age. Pooled mean differences between the reference and pregnant FMD values were calculated for predefined intervals of gestational age. Fourteen studies that enrolled 1231 participants met the inclusion criteria. Publication dates ranged from 1999 to 2014. In uncomplicated pregnancy, FMD was increased in the second and third trimesters. Between 15 and 21 weeks of gestation, absolute FMD increased the most, by a mean (95% CI) of 1.89% (0.25-3.53%). This was a relative increase of 22.5% (3.0-42.0%) compared with the non-pregnant reference. BAD increased progressively, in a steady manner, by the second trimester but not significantly in the first half of the second trimester. We could not discern differences in FMD and BAD between complicated and uncomplicated pregnancies at 29-35 weeks' gestation, reported in the three studies that met our inclusion criteria. Despite the increase in FMD and BAD throughout gestation, both reference curves were characterized by wide 95% CIs. During healthy pregnancy, endothelium-dependent vasodilatation and BAD increase. Women with a complicated pregnancy had FMD values within the lower range when
Full Text Available Pregnancy is a period when woman’s body undergoes a lot of changes in her hormonal balance, lymphatic system, musculoskeletal system and cardiovascular system. As a result of disorders in defense mechanisms, a significant amount of liquid accumulates in spaces between tissues. A clinical manifestation of this condition is swelling located around ankles and lower legs. Sedentary lifestyle, unhealthy eating habits, excessive weight and pregnancy are also well known causes of lymphatic swelling. Comprehensive anti-swelling therapy that is used in treating lymphatic swelling in pregnant patients includes: patients’ education, manual lymphatic drainage, kinesitherapy, multilayer bandaging, skin care, drainage positions and kinesiotaping. Dissertation’s objective: Dissertation’s objective is to evaluate implementation of manual lymphatic drainage and anti-swelling kinesiotaping in pregnant woman with lymphatic swelling of lower legs. Research methods: Research methods were collected basing on: interview with a patient, medical documentation analysis and physical examination conduced before and after therapy. Research was conducted between 34th and 36th week of pregnancy. Case study: 38 year old patient in her fourth singleton pregnancy. Two prior pregnancies in 2009 and 2010 were delivered with C-section and one missed abortion in 2015 occurred. During this pregnancy patient gained over 30kg. She was diagnosed with lymphatic swelling of metatarsus, lower legs and ankles in 34th week of pregnancy. Lymphatic drainage of lower limbs and anti-swelling kinesiotaping was implemented. Results: After two weeks of therapy decrease in swelling was observed in left lower limb: in metatarsus by 8cm, in ankles by 9cm and in lower legs by 6cm. In right lower limb swelling decreased accordingly by 7cm, 10cm and 5cm. Conclusion: Anti-swelling lymphatic drainage, kinesiotherapy and kinesiotaping are effective physiotherapy methods used in treating lymphedema

Transient osteoporosis of pregnancy (TOP) is a rare yet perhaps under-reported condition that has affected otherwise healthy pregnancies throughout the world. The condition presents suddenly in the third trimester of a usually uneventful pregnancy and progressively immobilizes the mother. Radiographic studies detect drastic loss of bone mass, elevated rates of turnover in the bone, and oedema in the affected portion. Weakness of the bone can lead to fractures during delivery and other complications for the mother. Then, within weeks of labour, symptoms and radiological findings resolve. Aetiology is currently unknown, although neural, vascular, haematological, endocrine, nutrient-deficiency, and other etiologies have been proposed. Several treatments have also been explored, including simple bed rest, steroids, bisphosphonates, calcitonin, induced termination of pregnancy, and surgical intervention. The orthopedist plays an essential role in monitoring the condition (and potential complications) as well as ensuring satisfactory outcomes for both the mother and newborn.

To compare the characteristics of preterm premature rupture of membranes (PPROM) between twin and singleton pregnancies. This was a retrospective study of all women with twin and singleton pregnancies admitted with PPROM between 24-34 weeks of gestation. Overall 698 women with PPROM were eligible for the study: 101 (14.5%) twins and 597 (85.5%) singletons. Twins presented with PPROM at a more advanced gestational age compared with singletons (29.1 ± 2.7 vs. 28.5 ± 2.8 weeks, p = 0.03). The latency period was shorter in twins compared with singletons, especially for women presenting after 28 weeks of gestation (5.0 ± 0.8 vs. 7.0 ± 0.4 days, p = 0.01). Women with twins were more likely to deliver within 48 h (OR: 2.7; 95%CI: 1.7-4.2) and were less likely to deliver within 2-7 days (OR: 0.5; 95%CI: 0.3-0.9) following PPROM. The rate of clinical chorioamnionitis or placental abruption following PPROM was lower in twins compared with singletons (15.8% vs. 26.0%, p = 0.03). PPROM in twin pregnancies tends to occur at a more advanced gestational age, is associated with a shorter latency period and is less likely to be complicated by chorioamnionitis or placental abruption compared with singletons. This information may be useful for counseling and management decisions in cases of PPROM in women with twins.

To study glucose profiles of gestational diabetes (GDM) patients with 72 h of continuous glucose monitoring (CGM) either before (GDM1) or after (GDM2) dietary counseling, comparing them with nondiabetic (NDM) controls. We performed CGM on 22 GDM patients; 11 before and 11 after dietary counseling and compared them to 11 healthy controls. Several physiological and clinical characteristics of the glucose profiles were compared across the groups, including comparisons for pooled 24-h measures and hourly median values, summary measures representing glucose exposure (area under the median curves) and variability (amplitude, standard deviation, interquartile range), and time points related to meals. Most women (81.8%) in the GDM groups had fasting glucose 0.05). Both GDM groups spent more time with glucose levels above 140mg/dL when compared with the NDM group. No differences among the groups were found for: pooled measurements and hourly comparisons, exposure, nocturnal, fasting, between lunch and dinner and before meals, as well as after lunch (P>0.05 for all). The main differences between the mild GDM1 group and healthy controls were related to glucose variability and excursions above 140mg/dL, while glucose exposure was similar. Glucose levels after breakfast and dinner also discerned the GDM1 group. Dietary counseling was able to keep glucose levels to those of healthy patients. © 2016 European Society of Endocrinology.

The occurrence of multiple births has been recognized as a risk factor for child maltreatment. However, few population-based studies have examined the relationship between multiple births and child maltreatment. This study aimed to evaluate the degree of risk of child maltreatment among singletons and multiple births in Japan and to identify factors associated with increased risk. Using population-based data, we analyzed the database of records on child maltreatment and medical checkups for infants aged 1.5 years filed at Nishinomiya City Public Health Center between April 2007 and March 2011. To protect personal information, the data were transferred to anonymized electronic files for analysis. After adjusting by logistic regression for each associated factor and gestation number, multiples themselves were not associated with the risk of child maltreatment. However, compared with singletons, multiples had a significantly higher rate of risk factors for child maltreatment, including low birth weight and neural abnormality. Moreover, compared with mothers of singleton, mothers of twins had a significantly higher rate of poor health, which is a risk factor of child maltreatment. Multiples were not associated with the risk of child maltreatment. However, compared with singletons, multiples and their mothers had a significantly higher rate of risk factors of child maltreatment.

Full Text Available The aim of this study was to screen neurodevelopmental impairment of preterm twins born at less than 34 weeks of gestation, compare them with the outcome of preterm singletons, and to determine potential neonatal factors adversely related to motor and cognitive outcome. Twins of 25-34 weeks gestation were included in the study. In total, 46 twins were matched with 46 singletons and were followed prospectively to 24 months corrected age. Obstetrical and neonatal data were recorded. All infants were assessed using the Bayley Scales of Infant and Toddler Development III For all morbidities, a significant difference could not be demonstrated. At 24 month follow up there was no significant difference in the cognitive outcome for the twins compared to singletons [98.6 (± 10.4 vs 97.8 (± 9.7, respectively]. There was also no significant difference in the motor outcome for the twins compared to singletons [94.8 (± 12.4 vs 98.1 (± 9.6., respectively]. For the twins, we found a link between pre-eclampsia and abnormal cognitive (p = 0.012 and motor (p = 0.030 results. With the number of twins steadily increasing, close developmental monitoring and probably early intervention services are needed to determine future directions for research.

Twins have inconsistently shown poorer outcomes than singletons. Although a high proportion of twins are born very preterm, data are sparse on the long-term outcomes in very preterm twins. The objective of this study was to compare mortality and neurodevelopmental outcomes of very preterm singletons and twins and to study outcomes in relation to factors specific to twins. Birth cohort study Etude Epidemiologique sur les Petits Ages Gestationnels (EPIPAGE). Nine regions in France. All very preterm live births occurring from 22 to 32 weeks of gestation in all maternity wards of nine French regions in 1997 (n=2773). Neurodevelopmental status, including cerebral palsy, and a cognitive assessment with the Kaufman Assessment Battery for Children, with scores on the Mental Processing Composite (MPC) scale, was available for 1732 and 1473 children at 5 years of age, respectively. Among live births, twins had higher hospital mortality than singletons (adjusted (a)OR: 1.4 (95% CI 1.1 to 1.9)). Among survivors, there was no crude difference at 5 years between twins and singletons in the prevalence of cerebral palsy (8.0% vs 9.1%, respectively), MPC <70 (9.5% vs 11.1%) and mean MPC (94.6 vs 94.4). However, after adjustment for sex, gestational age, intrauterine growth restriction and social factors, twins were more likely to have lower MPC scores (mean difference: -2.4 (95% CI-4.8 to 0.01)). Live born twins had a higher risk of mortality when birth weight discordance was present (aOR:2.9 (95% CI 1.7 to 4.8)), but there were no differences in long-term outcomes. Compared with very preterm singletons, twins had higher mortality, no difference with respect to severe deficiencies, but slightly lower MPC scores at 5 years.

In the present study, we examined whether a peripheral size-singleton distractor that matches the target-distractor size relation can capture attention and disrupt central target identification. Three experiments consistently showed that a size singleton that matches the target-distractor size relation cannot capture attention when it appears outside of the attentional window, even though the same size singleton produces a cuing effect. In addition, a color singleton that matches the target color, instead of a size singleton that matches the target-distractor size relation, captures attention when it is outside of the attentional window. Thus, a size-relation-matched distractor is much weaker than a color-matched distractor in capturing attention and cannot capture attention when the distractor appears outside of the attentional window.

To estimate the cost of preeclampsia from the national health payer's perspective using secondary data from the SCOPE study (Screening for Pregnancy End Points). SCOPE is an international observational prospective study of healthy nulliparous women with singleton pregnancies. Using data from the Irish cohort recruited between November 2008 and February 2011, all women with preeclampsia and a 10% random sample of women without preeclampsia were selected. Additional health service use data were extracted from the consenting participants' medical records for maternity services which were not included in SCOPE. Unit costs were based on estimates from 3 existing Irish studies. Costs were extrapolated to a national level using a prevalence rate of 5% to 7% among nulliparous pregnancies. Within the cohort of 1774 women, 68 developed preeclampsia (3.8%) and 171 women were randomly selected as controls. Women with preeclampsia used higher levels of maternity services. The average cost of a pregnancy complicated by preeclampsia was €5243 per case compared with €2452 per case for an uncomplicated pregnancy. The national cost of preeclampsia is between €6.5 and €9.1 million per annum based on the 5% to 7% prevalence rate. Postpartum care was the largest contributor to these costs (€4.9-€6.9 million), followed by antepartum care (€0.9-€1.3 million) and peripartum care (€0.6-€0.7 million). Women with preeclampsia generate significantly higher maternity costs than women without preeclampsia. These cost estimates will allow policy-makers to efficiently allocate resources for this pregnancy-specific condition. Moreover, these estimates are useful for future research assessing the cost-effectiveness of preeclampsia screening and treatment. © 2017 American Heart Association, Inc.

To evaluate the implementation of a complex intervention in the antenatal healthcare field in 14 Dutch municipalities. The intervention consisted of the implementation of a systematic scorecard-based risk assessment in pregnancy, subsequent patient-tailored care pathways, and consultations of professionals from different medical and social disciplines. Saunders's seven-step method was used for the development of a programme implementation monitoring plan, with specific attention to the setting and context of the programme. Data were triangulated from multiple sources, and prespecified criteria were applied to examine the evidence for implementation. Six out of 11 municipalities (54%) met the implementation criteria for the entire risk assessment programme, whereas three municipalities (27%) met the criteria if the three components of implementation were analysed separately. A process evaluation of implementation of a complex intervention is possible. The results can be used to improve understanding of the associations between specific programme elements and programme outcomes on effectiveness of the intervention. Additionally, the results are important for formative purposes to assess how future implementation of antenatal risk assessment can be improved in comparable contexts. Copyright © 2017.

Full Text Available Small for gestational age (SGA infants comprise up to 50% of all stillbirths and a minority are detected before birth. We aimed to develop and validate early pregnancy predictive models for SGA infants.5628 participants from SCOPE, a prospective study of nulliparous pregnant women, were interviewed at 15 ± 1 weeks' gestation. Fetal anthropometry, uterine and umbilical Doppler studies were performed at 20 ± 1 weeks'. The cohort was divided into training (n = 3735 and validation datasets (n = 1871. All-SGA (birthweight 12 months to conceive, university student, cigarette smoking, proteinuria, daily vigorous exercise and diastolic blood pressure ≥ 80. Recreational walking ≥ 4 times weekly, rhesus negative blood group and increasing random glucose were protective. AUC for clinical risk factors was 0.63. Fetal abdominal or head circumference z scores <10(th centile and increasing uterine artery Doppler resistance at 20 ± 1 weeks' were associated with increased risk. Addition of these parameters increased the AUC to 0.69. Clinical predictors of Normotensive and Hypertensive-SGA were sub-groups of All-SGA predictors and were quite different. The combined clinical and ultrasound AUC for Normotensive and Hypertensive-SGA were 0.69 and 0.82 respectively.Predictors for SGA of relevance to clinical practice were identified. The identity and predictive potential differed in normotensive women and those who developed hypertension.

Are women with endometriosis who conceive with IVF at increased risk of preterm birth? Women with endometriosis who conceive with IVF do not face an increased risk of preterm birth. The eutopic endometrium of women with endometriosis has been repeatedly shown to present molecular and cellular alterations. On this basis, it has been hypothesized that pregnancy outcome may be altered in affected women. However, to date, available evidence from epidemiological studies is scanty and conflicting. Data tended to be partly consistent only for an increased risk of preterm birth and placenta previa. Retrospective matched case-control study of women achieving an IVF singleton pregnancy progressing beyond 12 weeks' gestation. Women achieving IVF singleton pregnancies that progressed beyond 12 weeks' gestation at two infertility units were reviewed. Cases were women with a history of surgery for endometriosis and/or with a sonographic diagnosis of the disease at the time of the IVF cycle. Controls were women without current or past evidence of endometriosis who were matched to cases by age (± 6 months), type of cycle (fresh or frozen cycle) and study period. Male factor and unexplained infertility were the most common diagnoses in the control group. Two hundred and thirty-nine women with endometriosis and 239 controls were selected. The main outcome of the study was the rate of preterm birth (birth IVF pregnancies only, and specific data from properly designed studies are required to support any inference for natural pregnancies. The results of our study suggest that women with endometriosis conceiving with IVF can be reassured regarding the risk of preterm birth. The observed association with placenta previa requires further investigation and may open a new avenue of research. No external funding was used for this study.

During pregnancy, iron needs to increase substantially to support fetoplacental development and maternal adaptation to pregnancy. To meet these iron requirements, both dietary iron absorption and the mobilization of iron from stores increase, a mechanism that is in large part dependent on the iron-regulatory hormone hepcidin. In healthy human pregnancies, maternal hepcidin concentrations are suppressed in the second and third trimesters, thereby facilitating an increased supply of iron into the circulation. The mechanism of maternal hepcidin suppression in pregnancy is unknown, but hepcidin regulation by the known stimuli (i.e., iron, erythropoietic activity, and inflammation) appears to be preserved during pregnancy. Inappropriately increased maternal hepcidin during pregnancy can compromise the iron availability for placental transfer and impair the efficacy of iron supplementation. The role of fetal hepcidin in the regulation of placental iron transfer still remains to be characterized. This review summarizes the current understanding and addresses the gaps in knowledge about gestational changes in hematologic and iron variables and regulatory aspects of maternal, fetal, and placental iron homeostasis. © 2017 American Society for Nutrition.

Many hot subdwarf B stars (sdBs) are in close binaries, and the favored formation channels for subdwarfs rely on mass transfer in a binary system to strip a core He-burning star of its envelope. However, these channels cannot account for sdBs that have been observed in long-period binaries nor the narrow mass distribution of isolated (or 'singleton') sdBs. We propose a new formation channel involving the merger of a helium white dwarf and a low-mass, hydrogen-burning star, which addresses these issues. Hierarchical triples whose inner binaries merge and form sdBs by this process could explain the observed long-period subdwarf+main-sequence binaries. This process would also naturally explain the observed slow rotational speeds of singleton sdBs. We also briefly discuss the implications of this formation channel for extreme horizontal branch morphology in globular clusters and the UV upturn in elliptical galaxies.

Previous studies have shown that a sudden color change is typically less salient in capturing attention than the onset of a new object. Von Mühlenen, Rempel, and Enns (Psychological Science 16: 979-986, 2005) showed that a color change can capture attention as effectively as the onset of a new object given that it occurs during a period of temporal calm, where no other display changes happen. The current study presents a series of experiments that further investigate the conditions under which a change in color captures attention, by disentangling the change signal from the onset of a singleton. The results show that the item changing color receives attentional priority irrespective of whether this change goes along with the appearance of a singleton or not.

To illustrate the use of regression and logistic regression models to investigate changes over time in size of babies particularly in relation to social deprivation, age of the mother and smoking. Mean birthweight has been found to be increasing in many countries in recent years, but there are still a group of babies who are born with low birthweights. Population-based retrospective cohort study. Multiple linear regression and logistic regression models are used to analyse data on term 'singleton births' from Scottish hospitals between 1994-2003. Mothers who smoke are shown to give birth to lighter babies on average, a difference of approximately 0.57 Standard deviations lower (95% confidence interval. 0.55-0.58) when adjusted for sex and parity. These mothers are also more likely to have babies that are low birthweight (odds ratio 3.46, 95% confidence interval 3.30-3.63) compared with non-smokers. Low birthweight is 30% more likely where the mother lives in the most deprived areas compared with the least deprived, (odds ratio 1.30, 95% confidence interval 1.21-1.40). Smoking during pregnancy is shown to have a detrimental effect on the size of infants at birth. This effect explains some, though not all, of the observed socioeconomic birthweight. It also explains much of the observed birthweight differences by the age of the mother. Identifying mothers at greater risk of having a low birthweight baby as important implications for the care and advice this group receives. © 2012 Blackwell Publishing Ltd.

The aim was to determine the difference in intelligence between singletons and twins in young adulthood. Data from the Medical Birth Register of Norway were linked with register data from the Norwegian National Conscript Service. The study base consisted of data on the 445,463 males who were born alive in either single or twin births in Norway during 1967-1984 and who were examined at the time of the mandatory military conscription (age 18-20). Within this study base, there were data on 1,653 sibships of full brothers that included at least one man born in single birth and at least one man born in twin birth (4,307 persons, including 2,378 twins and 1,929 singletons). The intelligence scores of the singletons were 11% (95% confidence interval [CI]: 9-14%) of a standard deviation higher than those of the twins, after adjustment for birth year, birth order, parental ages at delivery, parental education levels, and other factors. The adjusted within-family difference was also 11% (95 % CI: 6-16%) of a standard deviation, indicating that unmeasured factors shared by siblings (e.g., maternal body height) have not influenced the estimate in important ways. When gestational age at birth was added to the model, the estimate for the difference in intelligence score was approximately the same. Including birth weight in the model strongly reduced the estimate. In conclusion, twins born in Norway during 1967-1984 had slightly lower intelligence in early adulthood compared with the singletons.

Full Text Available Despite documented health benefits for mother and baby, physical activity (PA-level tends to decline in pregnancy. Overweight/obese and physically inactive women are two selected groups at increased risk of pregnancy complications. Thus, efficient strategies to maintain or increase PA-level in pregnancy and the postpartum period, especially among these women, are warranted. This secondary analysis examined the effect of a prenatal lifestyle-intervention on PA-level in late pregnancy and the first year postpartum, with subanalysis on initially physically active versus inactive and normal-weight versus overweight/obese women.The Norwegian Fit for Delivery (NFFD randomized controlled trial included healthy primiparous women with singleton pregnancies and body mass index (BMI ≥19 kg/m2 assigned to an intervention group, n = 303 (twice weekly group-exercises and dietary counseling or a control group, n = 303 (standard prenatal care.

Postpartum depression is associated with negative physical and mental health outcomes for both the mother and infant. This study examines the relationship between a mother and/or her partner's pregnancy intentions and reported post-partum depressive symptoms (PPDs). Using Louisiana pregnancy risk assessment monitoring system, 2000-2003, a secondary cross-sectional analysis was conducted on 5549 mothers, stratified by race, who delivered a singleton, live birth and whose infant was still alive at the time of the survey. Bivariate and multivariable logistic regressions were conducted, taking into account the complex survey design. In multivariable models, unwanted pregnancies were associated with severe PPDs (aOR 1.76, 95 % CI 1.23-2.53). Furthermore, the association between husbands/partners' who did not want or care about the pregnancy and mild PPDs remained for White women (aOR 1.32, 95 % CI 1.02-1.69); while among Black women, neither parent's pregnancy intention were associated with mild or severe PPDs. This study supports existing research demonstrating the association between pregnancy intention and PPDs. This study contributes to the limited information on the role that partner pregnancy intention plays on maternal mental health outcomes, however further discussion is needed on the impact of this role across races. Findings can be used in programs aiming to reduce adverse mental health outcomes among high-risk mothers.

A cohort of 1782 children sampled from the Danish National Birth Cohort. The children were tested with a neuropsychological battery at age five. In addition to tests of intelligence, attention and executive functions, the follow up included extensive information on important covariates. The analyses were conducted using multiple linear regression and adjusted for parental educational level, maternal intelligence, age, parity, body mass index, smoking in pregnancy, alcohol consumption in pregnancy and child gender, child age, and examiner. Wechsler Preschool and Primary Scale of Intelligence-Revised, the Test of Everyday Attention for Children at Five, and the Behavior Rating Inventory of Executive Functions scores. A consistent pattern of nonsignificantly lower scores were only observed for intelligence and executive functions in children born after fertility treatment or by subfertile parents when the results were unadjusted for maternal intelligence and parental educational level. When adjusted for these and other covariates, there were no significant mean differences in intelligence (mean difference -2.8, 95% CI -7.8, 2.2), overall attention (-0.1, 95% CI -0.6, 0.3), or parent-rated executive functions (-0.1, 95% CI -3.0, 2.9) between children born after spontaneous conception and children born to parents conceiving after fertility treatment. Similarly, there were no significant mean differences in intelligence (mean difference 0.6, 95% CI -2.2, 3.4), overall attention (0.1, 95% CI -0.2, 0.4), or parent-rated executive functions (1.0, 95% CI -1.8, 3.7) between children born after spontaneous conception and children born to subfertile parents waiting more than 12 months before conceiving naturally. This study suggests that parental subfertility and fertility treatment are

Full Text Available Objective: To investigate the incidence and etiology of pregnancy complications associated with thrombophilic factors. Methods: Fifty-four patients with complicated pregnancy and 40 healthy pregnant subjects were included the study. Factor V Leiden (FVL mutation, protein S, protein C, anti-thrombin deficiency levels were investigated. Results: Of the 54 patients with complicated pregnancy, 29 had preeclampsia, 18 had intra uterine growth retardation, and 7 had intrauterine fetal loss. The most common defect was FVL mutation. FVL mutations in patient group and the control group were 27.2% and 10%, respectively, which were statistically significant. The protein S, protein C, and anti-thrombin deficiencies were found higher in the patient group compared to control (p>0.05 for each. Conclusion: FVL mutation was found higher in patient group compared to the control group, Protein C deficiency and anti-thrombin deficiency were related to preeclampsia but not other pregnancy complications. Clinicians should take into account the thrombophilia in complicated pregnancy, especially preeclampsia. J Clin Exp Invest 2013; 4 (4: 497-502

Full Text Available Abstract Background The appropriateness of an individual's intra uterine growth is now considered an important determinant of both short and long term outcomes, yet currently used measures have several shortcomings. This study demonstrates a method of assessing appropriateness of intrauterine growth based on the estimation of each individual's optimal newborn dimensions from routinely available perinatal data. Appropriateness of growth can then be inferred from the ratio of the value of the observed dimension to that of the optimal dimension. Methods Fractional polynomial regression models including terms for non-pathological determinants of fetal size (gestational duration, fetal gender and maternal height, age and parity were used to predict birth weight, birth length and head circumference from a population without any major risk factors for sub-optimal intra-uterine growth. This population was selected from a total population of all singleton, Caucasian births in Western Australia 1998–2002. Births were excluded if the pregnancy was exposed to factors known to influence fetal growth pathologically. The values predicted by these models were treated as the optimal values, given infant gender, gestational age, maternal height, parity, and age. Results The selected sample (N = 62,746 comprised 60.5% of the total Caucasian singleton birth cohort. Equations are presented that predict optimal birth weight, birth length and head circumference given gestational duration, fetal gender, maternal height, age and parity. The best fitting models explained 40.5% of variance for birth weight, 32.2% for birth length, and 25.2% for head circumference at birth. Conclusion Proportion of optimal birth weight (length or head circumference provides a method of assessing appropriateness of intrauterine growth that is less dependent on the health of the reference population or the quality of their morphometric data than is percentile position on a birth weight

Objective: This study explored the association between air pollution exposure and birth weight by using the multilevel linear model, after controlling related meteorological factors and individual differences of both mothers and babies. Methods: Women of childbearing age who were pregnant in Xi'an from 2010 to 2013, were selected as objects of this study. Multistage random sampling method was used to select 4 631 subjects followed by a self-designed questionnaire survey. Data related to quality of air and meteorology were gathered from routine monitoring system. Gestational age and date of birth, together with the average levels of air pollution were calculated for each trimester on each mother, and then the impact of air pollution on birth weight was assessed. A multilevel linear model was employed to investigate the association between the levels of exposure to air pollution by birth weight. Confounding factors were under control. We established three models in this study: Model 1 which involving the variable of air pollution exposure. Model 2 was adjusted for variables in Model 1 plus some other individual differences of both mother and baby. Model 3 was adjusted for variables in Model 2 plus meteorological factors. Results: There were significant differences seen in birth weight within the subgroups of gender, gestational age, mother's reproductive age, maternal education, residential areas and family incomes ( P 0.05). Data from Model 3 indicated that a decrease of 13.3 g(10.9 g in Model 2) and 6.6 g (5.9 g in Model 2) in birth weight that were associated with an increase of 10 μg/m(3) in the average level of NO(2) and PM(10) during the second trimester; A decrease of 13.7 g (9.8 g in Model 2) in birth weight was associated with an increase of 10 μg/m(3) in the average level of NO(2) during the third trimester. Conclusion: After controlling for meteorological factors, the levels of exposure to NO(2) and PM(10) during the second trimester and NO(2) during the third trimester were negatively associated with birth weight.
Ultrasound measurement of cervical length in the general population enables the identification of women at risk for spontaneous preterm delivery. Vaginal progesterone is effective in reducing the risk of preterm delivery in this population. This screening associated with treatment by vaginal progesterone is cost-effective. Universal screening of cervical length can therefore be considered justified. Nonetheless, this screening will not appreciably reduce the preterm birth prevalence: in France or UK, where the preterm delivery rate is around 7.4%, this strategy would make it possible to reduce it only to 7.0%. This small benefit must be set against the considerable effort required in terms of screening ultrasound scans. Universal ultrasound screening of cervical length is the inverse of Pareto's principle: a small benefit against a considerable effort. © 2016 Royal College of Obstetricians and Gynaecologists.
Full Text Available In the current study, we tested whether a masked and, thus, invisible singleton-cue captures atten-tion in a stimulus-driven manner or in a top-down contingent manner. The manual RT (Reaction Time capture effect with the invisible singleton--cue decreased substantially when a match between the singleton-cue and the top-down controlled set of searched-for target features was also decreased. By contrast, with the PCN (Posterior Contralateral Negativity, an electrophysiological measure of the capture of visuospatial attention by the invisible singleton-cue, no significant decrement was observed. Taken together, the results support the assumption that an invisible singleton-cue can capture attention in a stimulus-driven manner, and that different delays in the deallocation of attention (i.e., attention is deallocated more efficiently from acue that does not match the top-down controlled set than from a cue that does match the same set account for the weaker manual RT capture effect with a set- -nonmatching invisible singleton-cue.

Twenty-five shelves of tissue, all having a free edge within the uterine cavity, were identified by sonography in 24 singleton pregnancies. In no case did the shelf attach to the fetus or restrict fetal motion. The fetus was sonographically normal in 23 pregnancies, and no fetus developed amniotic-band syndrome. One fetus had anencephaly, probably unrelated to amniotic-band syndrome. Although these shelves may be due to synechiae, only eight (32%) of the patients had a history of dilatation and curettage or cesarean delivery, which predispose the patient to formation of synechiae. This experience suggests that when a shelf of tissue with a free edge is present within the pregnant uterus, there should be no concern for the development of amniotic-band syndrome as long as a complete sonographic survey of the fetus reveals no abnormalities.

To examine the relationship between asthmatic pregnancies and selected maternal and neonatal outcomes in a representative cohort. A retrospective cohort study was conducted at the Aga Khan University Hospital during the year 2004. A random selection was made of 65 asthmatic and 63 non-asthmatic singleton births. The neonatal outcomes studied were birth weight, premature birth and Apgar scores at 1 and 5 minutes. The maternal outcomes studied were number of hospital admissions, and number of documented UTI during the studied pregnancy and past history of abortions and stillbirths. The mean age of asthmatics and nonasthmatics were 28.0 +/- 4.9 years and 27.7 +/- 3.6 years respectively. The average parity among asthmatic women was 2.97 while that in controls was 2.57 (p UTIs and hospital admissions. Asthmatic pregnancies are more likely to result in abortion, premature delivery and low birth weight babies. The asthmatic pregnancies were also linked with higher rates of maternal UTI. Thcrefore a more vigilant monitoring is required in asthmatic pregnancies.

A computer spreadsheet was developed to predict the economic impact of a management decision to use B-mode ultrasonographic ovine pregnancy diagnosis. The spreadsheet design and spreadsheet cell formulas are provided. The program used the partial farm budget technique to calculate net return (NR) or cash flow changes that resulted from the decision to use ultrasonography. Using the program, either simple pregnancy diagnosis or pregnancy diagnosis with the ability to determine singleton or multiple pregnancies may be compared with no flock ultrasonographic pregnancy diagnosis. A wide range of user-selected regional variables are used to calculate the cash flow changes associated with the ultrasonography decisions. A variable may be altered through a range of values to conduct a sensitivity analysis of predicted NR. Example sensitivity analyses are included for flock conception rate, veterinary ultrasound fee, and the price of corn. Variables that influence the number of cull animals and the cost of ultrasonography have the greatest impact on predicted NR. Because the determination of singleton or multiple pregnancies is more time consuming, its economic practicality in comparison with simple pregnancy diagnosis is questionable. The value of feed saved by identifying and separately feeding ewes with singleton pregnancies is not offset by the increased ultrasonography cost.
Full Text Available Introduction Autoimmune hepatitis (AIH is a disease of unknown etiology. In pregnancy, it may have mild clinical course as well as can lead to liver failure, or exacerbation of clinical symptoms. In pregnant women the severity of symptoms is often observed between the second and third trimester, and in the puerperium. The disease is marked by enhanced activity of Th lymphocytes, which hepatocytes recognize as foreign antigens. This results in interleukin production activating B lymphocytes, and the production of specific antibodies attacking and destroying the hepatocytes. Case report A 35-year old patient, CII PII, 7 Hbd, with autoimmune hepatitis reported for a check-up. Her first pregnancy was 18 years ago, without history of underlying disease, carried to term without complications. The woman gave birth to a baby-son weighing 3,280g, 10 points Apgar. The delivery was spontaneous and uneventful. The patient got pregnant after an 18-year break. When she twice-tested positively for pregnancy, the treatment with azathioprine was switched to prednisolone. Over the pregnancy the patient was hospitalized 4 times, in 25, 29, 35, and 37 week of gestation due to a threat of preterm delivery, and pregnancy-related cholestasis associated with AIH. In 37 week of gestation, delivery was induced, and she gave birth to a healthy male, weighing 2,650 g, body height of 49 cm, 10 points Apgar scale. The liver function improved and stabilized after the delivery. Treatment with prednisolone has been continued, and the patient’s condition is still controlled. Pregnant patients with autoimmune hepatitis often experience exacerbation of the disease, especially in the third trimester, and in the postpartum period. This case shows that with proper care it is possible to continue and terminate pregnancy safely for the mother and her newly born baby.

The management of both male and female patients with inflammatory bowel disease (IBD) who wish to have a baby is challenging. For women, the most important factor to bear in mind is that the outcome of pregnancy is largely influenced by disease activity at the time of conception. Women with quiescent disease are likely to have an uncomplicated pregnancy with the delivery of a healthy baby, whereas women with active disease are more likely to have complications such as spontaneous abortions, miscarriages, stillbirths, and exacerbation of the disease. This is more true of patients with Crohn's disease than of patients with ulcerative colitis. Although the safety of medications used during pregnancy is an important issue, the impact of the medications used to treat IBD is less important in comparison to disease activity itself. 5-Aminosalicylic acid (5-ASA) products appear to be safe during pregnancy; corticosteroids are probably safe; 6-mercaptopurine and azathioprine should be used with caution; and methotrexate is contraindicated. There are inadequate data on the use of infliximab during pregnancy. In regard to men with IBD, the disease itself does not seem to have any negative impact on fertility. However, there is controversy about the effects of using 6-mercaptopurine and azathioprine prior to and during fertilization. In view of possible adverse pregnancy outcomes, it would be prudent to withhold 6-mercaptopurine and azathioprine therapy in men with IBD for 3 months prior to conception, when feasible. Most IBD medications should be continued before, during, and after pregnancy, with careful attention to the known cautions and exceptions. If IBD in a pregnant patient is in remission, the prognosis for pregnancy is the same as if she did not have IBD. Active disease should therefore be treated aggressively and remission accomplished before pregnancy is attempted. Similarly, a woman who unexpectedly becomes pregnant while her IBD is active should be treated

Although population-based studies indicate that on average, women gain 1-2kg between pregnancies, women with obesity often attribute its development to childbearing. There is little contemporary data available regarding how commonly this occurs, particularly in women of different body mass index (BMI) categories. The aim of this study was to examine inter-pregnancy weight changes among women at a tertiary obstetric hospital in Melbourne, Australia. This was a retrospective review of data from the Birthing Outcomes System electronic record of 19,617 women aged 20 years or older, who delivered at least two consecutive singleton infants at ≥37 weeks' gestation at Mercy Hospital for Women between December 1994 and December 2015. A logistic regression model was used to assess the relationship between gain of ≥4kg/m 2 between pregnancies and maternal BMI category in the first pregnancy, adjusting for covariates of maternal age, inter-pregnancy interval, and socioeconomic status. Gain of ≥4kg/m 2 between the first two pregnancies occurred in 7.5% of normal weight women, 10.5% of overweight women, and 13.4% of women with obesity. One in five women who were normal weight in their first pregnancy increased to overweight or obese BMI categories in their second pregnancy. Substantial weight gain in relation to pregnancy affects a considerable proportion of women. Since inter-pregnancy weight gain is associated with several complications in the next pregnancy and longer term, avoiding excessive weight gain during and between pregnancies may prevent adverse health consequences in mothers and offspring.

It is unanimously recognized that the maternal nutritional status at the pregnancy onset influence both short-term and long-term health of the mother and offspring. Among several nutrients, LCPUFA, particularly from the omega-3 family, are of utmost importance. This study was carried out to determine fatty acids profile of maternal erythrocyte membranes in early pregnancy and to identify potential determinants impacting on this status. A cohort of 122 healthy women with a singleton pregnancy was included. Fatty acids were analyzed using gas chromatography. Because of the lack of cutoff values, reference ranges were used to determine fatty acids categories. Of concern, our data revealed low monounsaturated and long-chain omega-3 fatty acid status in most participants. More than 75% of Belgian pregnant women exhibited Pal, AO and EPA levels as well as IOM3 values below the laboratory reference ranges. Higher DHA concentrations and IOM3 values were found among foreign-nationality participants, non-smokers and physically active women. With regard to dietary factors, omega-3 supplements and diet seem to be complementary since DHA from supplements (but not from diet) and EPA from diet (but not from supplements) were found to be associated with higher concentrations of DHA and EPA, respectively. Our study presents evidence demonstrating that the fatty acid status of most early pregnant women is far from being optimal based on the admitted general reference values. Clinicians should be advice to carefully evaluate and improve this status to guarantee the best possible outcome for both the mother and the baby.

This study was carried out to assess the platelet count in asymptomatic pregnant women at the time of delivery in local population. Six hundred and eighteen healthy pregnant women and 100 aged matched non-pregnant healthy women were randomly selected for the study and their platelet counts were estimated. Out of total 618 pregnant women at the time of delivery, 34 (5.5%) were having platelet count < 150x109/L and only 4 (0.65%) less than 100x109/L. All the thrombocytopaenic women were asymptomatic. About 5% of healthy women at term pregnancy are likely to have mild thrombocytopenia without suffering from any untoward clinical consequences. (author)

In non-pregnant individuals, a strong positive association of sodium intake with blood pressure has been established, but the relationship between sodium intake and blood pressure in human pregnancy remains obscure up to date. The aim of this prospective observational cohort study was to assess the relationship between urinary sodium excretion (as a measure for intake) and blood pressure from the early second trimester onwards throughout pregnancy. The study group consisted of 667 low-risk women with singleton pregnancies, of whom 350 were nulliparous and 317 parous. Blood pressure was measured in a standardised fashion at predetermined intervals from the first antenatal visit prior to 16 weeks gestation until delivery. Urinary sodium excretion was measured in 24-h urine collections on at least four occasions between 16 and 38 weeks gestation. Main outcome measures were the coefficients of correlation between changes in urinary sodium output and changes in blood pressure during six different gestational epochs. No significant correlations were found between changes in urinary sodium output and changes in blood pressure. Correlation coefficients were alike for nulliparous and parous women and for different gestational intervals. Prior to 32 weeks gestation, no differences were observed in sodium excretion between women who remained normotensive and those who developed gestational hypertension. These results suggest that changes in sodium intake are not associated with blood pressure changes in low-risk pregnant women. Blood pressure increases as observed in the second half of normotensive and hypertensive pregnancies are unlikely to be caused by changes in renal sodium handling.

To study whether placental weight in the first pregnancy is associated with preeclampsia in the second pregnancy. In this population-based study, we included all women with two consecutive singleton pregnancies reported to the Medical Birth Registry of Norway during 1999-2012 (n=186 859). Placental weight in the first pregnancy was calculated as z-scores, and the distribution was divided into five groups of equal size (quintiles). We estimated crude and adjusted odds ratios with 95% confidence intervals for preeclampsia in the second pregnancy according to quintiles of placental weight z-scores in the first pregnancy. The 3rd quintile was used as the reference group. Among women without preeclampsia in the first pregnancy, 1.4% (2507/177 149) developed preeclampsia in the second pregnancy. In these women, the risk for preeclampsia in the second pregnancy was associated with placental weight in the first pregnancy in both lowest (crude odds ratio (cOR) 1.30, 95% confidence interval (CI); 1.14-1.47) and highest quintile (cOR 1.20, 95% CI; 1.06-1.36). The risk associated with the highest quintile of placental weight was confined to term preeclampsia. Among women with preeclampsia in the first pregnancy, 15.7% (1522/9710) developed recurrent preeclampsia, and the risk for recurrent preeclampsia was associated with placental weight in lowest quintile in the first pregnancy (cOR 1.30, 95% CI; 1.10-1.55). Adjustment for interval between pregnancies, maternal diabetes, age, and smoking in the first pregnancy did not alter these estimates notably. Placental weight in the first pregnancy might help to identify women who could be at risk for developing preeclampsia in a second pregnancy. Copyright © 2017 The Authors. Published by Elsevier B.V.

Cardiac hypertrophy occurs during pregnancy as a consequence of both volume overload and hormonal changes. Both pregnancy- and exercise-induced cardiac hypertrophy are generally thought to be similar and physiological. Despite the fact that there are shared transcriptional responses in both forms of cardiac adaptation, pregnancy results in a distinct signature of gene expression in the heart. In some cases, however, pregnancy can induce adverse cardiac events in previously healthy women without any known cardiovascular disease. Peripartum cardiomyopathy is the leading cause of non-obstetric mortality during pregnancy. To understand how pregnancy can cause heart disease, it is first important to understand cardiac adaptation during normal pregnancy. This review provides an overview of the cardiac consequences of pregnancy, including haemodynamic, functional, structural, and morphological adaptations, as well as molecular phenotypes. In addition, this review describes the signalling pathways responsible for pregnancy-induced cardiac hypertrophy and angiogenesis. We also compare and contrast cardiac adaptation in response to disease, exercise, and pregnancy. The comparisons of these settings of cardiac hypertrophy provide insight into pregnancy-associated cardiac adaptation. PMID:24448313

Recently, an increasing interest has been addressed to the acid-base imbalance in the pathogenesis of diabetes while we are not aware of any study among patients affected by gestational diabetes mellitus (GDM). Therefore, the purpose of present study was to reveal the potential relation between dietary acid load (DAL) and glycemic indices, lipid profiles and GDM odds ratio among Iranian pregnant women with GDM. This case-control study (hospital-based setting) was performed in singleton fetus pregnant women; healthy (n = 263) and GDM (n = 200), aged 22-44 years, and between weeks 5-28 of pregnancy. Three-day 24-h dietary records were applied to determine usual intakes of women. The tertiles of protein to potassium ratio (Pr/K) and potential renal acid load (PRAL) were calculated and used for statistical analyses. Across tertiles of both DAL scores, fasting blood sugar, HbA1C, total cholesterol and LDL-C increased significantly. Diastolic blood pressure of participants significantly increased only across the tertiles of Pr/K ratio. Participants in the highest tertile of Pr/K and PRAL had more than 7 (OR = 7.60; 95% CI: 3.43-16.84) and 9 times (OR = 9.27; 95% CI: 4.00-21.46) increased odds of gestational diabetes mellitus, respectively. Women with higher scores of DAL were more likely to have gestational diabetes mellitus during pregnancy. Copyright © 2017. Published by Elsevier Ltd.

The cause of recurrent pregnancy loss often remains unknown. Possibly, pathophysiological pathways are shared with other pregnancy complications. All women with secondary recurrent pregnancy loss (SRPL) visiting Leiden University Medical Center (January 2000-2015) were included in this retrospective cohort to assess whether women with SRPL have a more complicated first pregnancy compared with control women. SRPL was defined as three or more consecutive pregnancy losses before 22 weeks of gestation, with a previous birth. The control group consisted of all Dutch nullipara delivering a singleton (January 2000-2015). Information was obtained from the Dutch Perinatal Registry. Outcomes were preeclampsia, preterm birth, post-term birth, intrauterine growth restriction, breach position, induction of labor, cesarean section, congenital abnormalities, perinatal death and severe hemorrhage in the first ongoing pregnancy. Subgroup analyses were performed for women with idiopathic SRPL and for women ≤35 years. In all, 172 women with SRPL and 1 196 178 control women were included. Women with SRPL were older and had a higher body mass index; 29.7 years vs. 28.8 years and 25.1 kg/m 2 vs. 24.1 kg/m 2 , respectively. Women with SRPL more often had a post-term birth (OR 1.86, 95% CI 1.10-3.17) and more perinatal deaths occurred in women with SRPL compared with the control group (OR 5.03, 95% CI 2.48-10.2). Similar results were found in both subgroup analyses. The first ongoing pregnancy of women with (idiopathic) SRPL is more often complicated by post-term birth and perinatal death. Revealing possible links between SRPL and these pregnancy complications might lead to a better understanding of underlying pathophysiology. © 2017 Nordic Federation of Societies of Obstetrics and Gynecology.

Is PGD associated with the risk of adverse perinatal outcomes such as pre-term birth (PTB) and low birth weight (LBW)? There was no increase in the risk of adverse perinatal outcomes of PTB, and LBW following PGD compared with autologous IVF. Pregnancies resulting from ART are associated with a higher risk of pregnancy complications compared with spontaneously conceived pregnancies. The possible reason of adverse obstetric outcomes following ART has been attributed to the underlying infertility itself and embryo specific epigenetic modifications due to the IVF techniques. It is of interest whether interventions such as embryo biopsy as performed in PGD affect perinatal outcomes. Anonymous data were obtained from the Human Fertilization and Embryology Authority (HFEA), the statutory regulator of ART in the UK. The HFEA has collected data prospectively on all ART performed in the UK since 1991. Data from 1996 to 2011 involving a total of 88 010 singleton live births were analysed including 87 571 following autologous stimulated IVF ± ICSI and 439 following PGD cycles. Data on all women undergoing either a stimulated fresh IVF ± ICSI treatment cycle or a PGD cycle during the period from 1996 to 2011 were analysed to compare perinatal outcomes of PTB and LBW among singleton live births. Logistic regression analysis was performed adjusting for female age category, year of treatment, previous IVF cycles, infertility diagnosis, number of oocytes retrieved, whether IVF or ICSI was used and day of embryo transfer. There was no increase in the risk of PTB and LBW following PGD versus autologous stimulated IVF ± ICSI treatment, unadjusted odds of PTB (odds ratio (OR) 0.68, 95% CI: 0.46-0.99) and LBW (OR 0.56, 95% CI: 0.37-0.85). After adjusting for the potential confounders, there was again no increase in the risk of the adverse perinatal outcomes following PGD: PTB (adjusted odds ratio (aOR) 0.66, 95% CI: 0.45-0.98) and LBW (aOR 0.58, 95% CI: 0.38-0.88).

In fuzzy modeling, the inputs of the simulated systems can receive both crisp values and non-Singleton. Computational complexity of fuzzy inference with fuzzy non-Singleton inputs corresponds to an exponential. This paper describes a new method of inference, based on the theorem of decomposition of a multidimensional fuzzy implication and a fuzzy truth value. This method is considered for fuzzy inputs and has a polynomial complexity, which makes it possible to use it for modeling large-dimensional MISO-structure systems.

Although pregnancy concentrations of some phenols have been associated with infant size at birth, there is limited data on the effect of preconception exposure. We aimed to examine paternal and maternal preconception and maternal prenatal urinary phenol concentrations in relation to birth weight and head circumference. We evaluated 346 singletons born to 346 mothers and 184 fathers (184 couples) from a prospective preconception cohort of subfertile couples from the Environment and Reproductive Health (EARTH) Study in Boston, USA. We used multiple urine samples collected before the index pregnancy in both men and women to estimate mean preconception urinary benzophenone-3, triclosan, butylparaben, propylparaben, methylparaben, or ethylparaben concentrations. We also estimated mean maternal prenatal urinary phenol concentrations by averaging trimester-specific urine samples. Birth weight and head circumference were abstracted from delivery records. We estimated the association of natural log-phenol concentrations with birth outcomes using multivariable linear regression models, adjusting for known confounders. In adjusted models, each log-unit increase in paternal preconception benzophenone-3 concentration was associated with a 137 g increase in birth weight (95% CI: 60, 214). Additional adjustment for prenatal benzophenone-3 concentration strengthened this association. None of the maternal preconception phenol concentrations were associated with birth weight. However, maternal prenatal triclosan concentrations were associated with a 38 g decrease in birth weight (95% CI: -76, 0). Few associations were observed between phenols and head circumference except for a decrease of 0.27 cm (95% CI: -54, 0) in relation to maternal preconception methylparaben concentration. Although our findings should be interpreted in light of inherent study limitations, these results suggest potential evidence of associations between some paternal or maternal phenol concentrations and

Parenting twins is typically portrayed as more stressful than is parenting single children and, therefore, more of a strain on the marital relationship. With this in mind, the present study examined the contribution of infant characteristics and mother's internal resources (attachment style) and external resources (maternal and paternal grandmothers' perceived support) to their marital adaptation during the first month following delivery, comparing mothers of twins (n = 88) with mothers of singletons (n = 82). The findings indicate that both internal and external resources contribute to the marital adaptation of the two groups, even beyond the contribution of specific circumstances. Thus, it seems that the birth of twins and the birth of a single child are normative life events that have more in common than previously acknowledged. The implications for the focus of social work interventions, particularly in the case of the birth of twins, are discussed.

Background: Although hypothyroidism is associated with increased morbidity, an association with increased mortality is still debated. Our objective was to investigate, at a nationwide level, whether a diagnosis of hypothyroidism influences mortality. Methods: In an observational cohort study from January 1, 1978 until December 31, 2008 using record-linkage data from nationwide Danish health registers, 3587 singletons and 682 twins diagnosed with hypothyroidism were identified. Hypothyroid individuals were matched 1:4 with nonhypothyroid controls with respect to age and gender and followed over a mean period of 5.6 years (range 0–30 years). The hazard ratio (HR) for mortality was calculated using Cox regression analyses. Comorbidity was evaluated using the Charlson score (CS). Results: In singletons with hypothyroidism, the mortality risk was increased (HR 1.52; 95% confidence interval [CI]: 1.41–1.65). Although the effect attenuated, hypothyroidism remained associated with increased mortality when evaluating subjects with a CS = 0 (HR 1.23; 95% CI: 1.05–1.44). In twin pairs discordant for hypothyroidism, the hypothyroid twin had excess mortality compared with the corresponding euthyroid cotwin (HR 1.40; 95% CI 0.95–2.05). However, after stratifying for zygosity, hypothyroidism was associated with excess mortality in dizygotic twin pairs (HR 1.61; 95% CI 1.00–2.58), whereas the association attenuated in monozygotic pairs (HR 1.06; 95% CI 0.55–2.05). Conclusions: Hypothyroidism is associated with an excess mortality of around 50%, which to some degree is explained by comorbidity. In addition, the finding of an association between hypothyroidism and mortality within disease discordant dizygotic but not monozygotic twin pairs indicates that the association between hypothyroidism and mortality is also influenced by genetic confounding.

Teen pregnancy is a social problem not resolved in developing and some developed countries. Adolescent fecundity has become the most exact bio-demographic and health indicator of development. In developing countries that are expected to follow the sexual behaviour patterns of developed countries, without offering the levels of education and services for adolescents, the consequences will be adolescent fecundity and STI prevalence increase. The ignorance about sexuality and reproduction both in parents, teachers and adolescents increases the early initiation of coital relations and of unwanted pregnancies. Extreme poverty and being the son or daughter of an adolescent mother are risk factors of repeating the early pregnancy model. The application of predictive risk criteria in pregnant adolescents to facilitate the rational use of Health Services to diminish the maternal and perinatal mortality is discussed as well as the social factors associated with adolescent pregnancy as socioeconomic levels, structure - types and characteristics of the family, early leaving school, schooling after delivery, female employment, lack of sexual education, parental and family attitudes in different periods of adolescent pregnancy, adolescent decisions on pregnancy and children, unstable partner relationship and adoption as an option. Social consequences are analyzed as: incomplete education, more numerous families, difficulties in maternal role, abandonment by the partner, fewer possibilities of having a stable, qualified and well-paid job, greater difficulty in improving their socioeconomic level and less probability of social advancement, lack of protection of the recognition of the child. Finally, based on evidence, some measures that can reduce adverse consequences on adolescent mothers, fathers and their children are suggested. Copyright © 2012 S. Karger AG, Basel.

Pre-pregnancy weight and gestational weight gain (GWG) are important factors in both maternal and infant outcomes. Little information is available in relation to different levels of pre-pregnancy body mass index (BMI) and body weight gain on obstetric outcomes in Taiwan. This study investigated the associations between pregnancy complications with pre-pregnant BMI and GWG, in Taiwanese women. Data were extracted from a delivery room information bank on all women delivering singleton babies in a medical center. Eight hundred and sixty pregnant women were included. The collected variables included basic information, GWG, and pregnancy and neonatal outcomes. Pregnant women were categorized according to their pre-pregnant BMI and GWG to evaluate the impacts of pre-pregnant BMI and maternal weight gain on the risk of pregnancy complications. Univariate and multivariable logistic regression analyses were performed, and odds ratios were calculated. Pre-pregnancy BMI>=24 kg/m2 increased the risks of gestational diabetes mellitus, preeclampsia, and preterm labor. Preeclampsia and Cesarean delivery were positively associated with high weight gains (>18 kg), whereas a low birth weight and preterm labor were strongly associated with low weight gains (14 kg in women who were underweight and normal weight before pregnancy. An appropriate maternal BMI (18.5-24 kg/m2) at conception followed by a suitable gestational weight gain (10-14 kg) has substantial impact on the overall health of pregnant women and would lead to better obstetric management for Taiwanese women.

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

The fetal anomaly ultrasound only detects 65 to 81 % of the patients with congenital heart disease, making it the most common structural fetal anomaly of which a significant part is missed during prenatal life. Therefore, we need a reliable non-invasive diagnostic method which improves the predictive value for congenital heart diseases early in pregnancy. Fetal electrocardiography could be this desired diagnostic method. There are multiple technical challenges to overcome in the conduction of the fetal electrocardiogram. In addition, interpretation is difficult due to the organisation of the fetal circulation in utero. We want to establish the normal ranges and values of the fetal electrocardiogram parameters in healthy fetuses of 18 to 24 weeks of gestation. Women with an uneventful singleton pregnancy between 18 and 24 weeks of gestation are asked to participate in this prospective cohort study. A certified and experienced sonographist performs the fetal anomaly scan. Subsequently, a fetal electrocardiogram recording is performed using dedicated signal processing methods. Measurements are performed at two institutes. We will include 300 participants to determine the normal values and 95 % confidence intervals of the fetal electrocardiogram parameters in a healthy fetus. We will evaluate the fetal heart rate, segment intervals, normalised amplitude and the fetal heart axis. Three months postpartum, we will evaluate if a newborn is healthy through a questionnaire. Fetal electrocardiography could be a promising tool in the screening program for congenital heart diseases. The electrocardiogram is a depiction of the intimate relationship between the cardiac nerve conduction pathways and the structural morphology of the fetal heart, and therefore particularly suitable for the detection of secondary effects due to a congenital heart disease (hypotrophy, hypertrophy and conduction interruption).

Pregnancy is a complex state where changes in maternal physiology have evolved to favor the development and growth of the placenta and the fetus. These adaptations may affect preexisting disease or result in pregnancy-specific disorders. Similarly, variations in physiology may alter the pharmacokinetics or pharmacodynamics that determines drug dosing and effect. It follows that detailed pharmacologic information is required to adjust therapeutic treatment strategies during pregnancy. Understanding both pregnancy physiology and the gestation-specific pharmacology of different agents is necessary to achieve effective treatment and limit maternal and fetal risk. Unfortunately, most drug studies have excluded pregnant women based on often-mistaken concerns regarding fetal risk. Furthermore, over two-thirds of women receive prescription drugs while pregnant, with treatment and dosing strategies based on data from healthy male volunteers and non-pregnant women, and with little adjustment for the complex physiology of pregnancy and its unique disease states. This review will describe basic concepts in pharmacokinetics and their clinical relevance and highlight the variations in pregnancy that may impact the pharmacokinetic properties of medications.

Diabetes insipidus is an uncommon pathology; its incidence varies from two to six cases in 100,000 pregnancies. It has multiple etiologies and it is classified in central and neurogenic. Patients with diabetes insipidus generally show intense thirst, polyuria, neurologic symptoms and hypernatremia. It does not seem to alter the patient's fertility. Diabetes insipidus is usually associated with pre-eclampsia, HELLP syndrome, and fatty liver disease of pregnancy. This is a report of a case seen at the Hospital General de Cholula, in Puebla, Mexico. A 19 year-old female, with 37.2 weeks of pregnancy, had a history of Langerhans cell histiocytosis since she was four years. Patient was treated with intranasal desmopressin until 2005. She went to an obstetric evaluation; laboratory and cabinet studies were obtained. A healthy 1900 g female was obtained through vaginal delivery, with a 7/9 Apgar score. We should be familiarized with this uncommon pathology because of its association with several obstetric emergencies.

This paper is the first reported investigation of the role of non-temporal acoustic cues in the singleton-geminate contrast in Lebanese Arabic, alongside the more frequently reported temporal cues. The aim is to explore the extent to which singleton and geminate consonants show qualitative differences in a language where phonological length is prominent and where moraic structure governs segment timing and syllable weight. Twenty speakers (ten male, ten female) were recorded producing trochaic disyllables with medial singleton and geminate fricatives preceded by phonologically short and long vowels. The following acoustic measures were applied on the medial fricative and surrounding vowels: absolute duration; intensity; fundamental frequency; spectral peak and shape, dynamic amplitude, and voicing patterns of medial fricatives; and vowel quality and voice quality correlates of surrounding vowels. Discriminant analysis and receiver operating characteristics (ROC) curves were used to assess each acoustic cue's contribution to the singleton-geminate contrast. Classification rates of 89% and ROC curves with an area under the curve rate of 96% confirmed the major role played by temporal cues, with non-temporal cues contributing to the contrast but to a much lesser extent. These results confirm that the underlying contrast for gemination in Arabic is temporal, but highlight [+tense] (fortis) as a secondary feature.

Contemporary fetal growth standards are created by using theoretical properties (percentiles) of birth weight (for gestational age) distributions. The authors used a clinically relevant, outcome-based methodology to determine if separate fetal growth standards are required for singletons and twins. All singleton and twin livebirths between 36 and 42 weeks' gestation in the United States (1995-2002) were included, after exclusions for missing information and other factors (n = 17,811,922). A birth weight range was identified, at each gestational age, over which serious neonatal morbidity and neonatal mortality rates were lowest. Among singleton males at 40 weeks, serious neonatal morbidity/mortality rates were lowest between 3,012 g (95% confidence interval (CI): 3,008, 3,018) and 3,978 g (95% CI: 3,976, 3,980). The low end of this optimal birth weight range for females was 37 g (95% CI: 21, 53) less. The low optimal birth weight was 152 g (95% CI: 121, 183) less for twins compared with singletons. No differences were observed in low optimal birth weight by period (1999-2002 vs. 1995-1998), but small differences were observed for maternal education, race, parity, age, and smoking status. Patterns of birth weight-specific serious neonatal morbidity/neonatal mortality support the need for plurality-specific fetal growth standards.

Full Text Available BACKGROUND Pregnancy is a physiological status of a woman. Every organ is adapting in order to accept another human body. The main changes occur in the endocrine, immune, metabolic and vascular systems. The skin is no exception. Many skin changes during pregnancy are considered to be normal or physiological including striae gravidarum or melasma. These physiological skin changes are usually well tolerated by the pregnant woman. There is no balance between these systems, however, and abnormalities can appear. Immunologic status of the woman plays an important role in the manifestations exhibited in the skin. Alterations of the skin during pregnancy can be classified as physiologic skin changes, changes in pre-existing skin diseases and specific dermatoses of pregnancy. MATERIALS AND METHODS 200 pregnant women with skin manifestations attending Dermatology and Obstetric departments attached to Government General Hospital, Kurnool, were studied. 1. A detailed proforma was taken, which included: a. Detailed history including chief complaints related to skin. b. Onset in relation to duration of pregnancy. c. Complete general physical and systemic examination. d. Associated skin/medical disorders. 2. Investigations-CBP, CUE, RBS, LFT, HBsAg, VDRL, HIV 1 and 2 were done routinely. 3. KOH mount, saline mount and skin biopsy performed wherever required. Inclusion criteria- All pregnant women having skin lesions were included in the study irrespective of the duration of pregnancy and gravidity. Exclusion criteria- Pregnant women having any underlying medical diseases. All pregnant women attending antenatal OPD and those admitted into wards having symptoms related to skin and mucosa, at KIMS Hospital are studied. 1. Detailed history including chief complaints related to skin. 2. Onset in relation to duration of pregnancy. 3. Complete general physical and systemic examination. 4.

Common established causes include uterine anomalies, antiphospholipid syndrome, hormonal and metabolic disorders, and cytogenetic abnormalities. Other etiologies have been proposed but are still considered controversial, such as chronic endometritis, inherited thrombophilias, luteal phase deficiency, and high sperm DNA fragmentation levels. Over the years, evidence-based treatments such as surgical correction of uterine anomalies or aspirin and heparin for antiphospholipid syndrome have improved the outcomes for couples with recurrent pregnancy loss. However, almost half of the cases remain unexplained and are empirically treated using progesterone supplementation, anticoagulation, and/or immunomodulatory treatments. Regardless of the cause, the long-term prognosis of couples with recurrent pregnancy loss is good, and most eventually achieve a healthy live birth. However, multiple pregnancy losses can have a significant psychological toll on affected couples, and many efforts are being made to improve treatments and decrease the time needed to achieve a successful pregnancy. This article reviews the established and controversial etiologies, and the recommended therapeutic strategies, with a special focus on unexplained recurrent pregnancy losses and the empiric treatments used nowadays. It also discusses the current role of preimplantation genetic testing in the management of recurrent pregnancy

The aim of this study was to find the perinatal risk factors of intravenricular hemorrhage in twin neonates. A retrospective analysis of 203 twin pregnancies and deliveries between 2003 and 2009 was performed. Then data according birth state and neonatal complications in 406 twins were analyzed. Twin outcome was compared with the outcome of 105 singletons born at the same time and at the same gestational age as twins. Intraventricular hemorrhage was diagnosed in 116/406 (29%) of twins. IVH was found two times more often in the analyzed group than in singletons born at the same gestational age (29% vs. 18%, p = 0,03). In 96% I and II grade hemorrhage was diagnosed and in 4% III and IV grade hemorrhage in the Papille scale was found. 1) Intraventricular hemorrhage is found more often in twins than in singleton neonates born at the same gestational age. 2) IVH in twins correlate with preterm birth and low birth weight. IVH occur more often in twins with birth weight discordance and with too small maternal weight gain.

The special aim was to find out if the anticonvulsive therapy has any correlation with the occurrence of fetal malformations in the studied group of women. In 43.9% of pregnant women with epilepsy, methyl-phenobarbitone as an anticonvulsive drug was administered, while carbamazepine was applied in 13.6% cases. A combination of phenytoin and phenobarbitone was prescribed in 18.9% of cases. Primidone was the drug of choice in 8% cases and 5.3% of patients were treated with various combinations of anticonvulsive drugs. Hyperemesis, threatened spontaneous abortion and premature labor complicated significantly more pregnancies in patients with epilepsy than on controls. Pregnancies from the studied group were terminated by the cesarean section in significantly more cases (11.2%) than in the control group (5.4%). Newborns from mothers with epilepsy had a statistically lower birthweight (3173 +/- 575 g) than those born from healthy mothers (3376 +/- 510g). Fifteen newborns or 11.2% were born with congenital malformations, while among the control group of newborns only two were malformed. It is noticed that the newborns from mothers treated with phenitoin and phenobarbitone had dysmorphic anomalies of the face more frequently. The drugs mentioned above interfere with the metabolism of K vitamin and as a result of this interreaction, mothers and newborns can suffer from coagulation disorders. In conclusion it is important to mention that no anticonvulsant drug seems to be absolutely safe when used during pregnancy since each of them has a teratogenic effect on the fetus.

To study the relationship between maternal diet and infant anthropometric measurements in 56 women, aged 28 +/- 5.1 years, with singleton pregnancies. The overall quality of the diet (three 24-hour recalls), including supplementation, was evaluated at 34 +/- 1.3 weeks using a total mean adequacy ratio (TMAR) of 12 nutrients. Specific interviewing techniques were used to minimize social desirability bias. Anthropometric measurements of both parents and maternal lifestyle practices were also obtained. Infant weight, crown-heel length and head circumference were measured 14.6 +/- 4.4 days after birth. Stepwise multiple regression analysis revealed that maternal diet quality (TMAR) was significantly related to infant weight (r = .039, P = .036) and crown-heel length (r = .071, P = .007). Other significant predictors included gestational age, maternal height, sex, smoking and physical activity. Maternal diet was positively associated with infant weight and crown-heel length.

First, to assess if there are any differences in birth weight or gestational length in newborns from egg-donation pregnancies delivering singletons, originating from either fresh or frozen-thawed embryos when they were developed and delivered within the same mothers. Second, to determine if there are any clinical, phenotypic, or laboratory factors influencing this relationship, including the origin of the oocyte (same or different donor), the order of the children (first fresh or first frozen-thawed embryo transfer), the embryo freezing technique (vitrification or slow freezing), the in vitro embryo culture length, and the duration that embryos remained frozen. Retrospective cohorts study. University-affiliated infertility centers. A total of 360 women undergoing oocyte donation (OD), delivering (>28 weeks) at least two babies, each one from a single pregnancy, originating from at least one fresh and one frozen-thawed embryo transfer, controlling maternal and laboratory characteristics, to test the effect of embryo freezing on children size (n = 731). None. Birth weight, gestational age, weight percentile, being large for gestational age (LGA), small for gestational age (SGA), size out of normal range (ONR = LGA + SGA), and macrosomy. From fresh versus thawed embryos, respectively, mean birth weight of children was 3,183.7 g versus 3,226.4 g, gestational age was 272.1 days versus 268.8 days, and mean weight percentiles were 47.6 versus 50.1. The proportions and corresponding odds ratios (ORs) from fresh versus thawed embryos, respectively, were for LGA 13.6% versus 11.3% (OR 0.81), for SGA 9.4% versus 12.5% (OR 1.37), for ONR 23.1% versus 23.8% (OR 1.04), and for macrosomy 0.3% versus 0.8% (OR 3.1). After adjusting for clinically relevant variables, the ORs were for LGA 0.96, for SGA 1.40, for ONR 1.20, and for macrosomy not computable. None of the stated measures were significantly different. Also, independent analyses run on the origin of the oocytes

The causes and mechanisms related to preterm delivery and intrauterine growth restriction are poorly understood. Our objective was to assess the direct and indirect effects of psychosocial and biomedical factors on the duration of pregnancy and fetal growth. A self-administered questionnaire was distributed to pregnant women attending prenatal ultrasound clinics in nine hospitals in the Montérégie region in the province of Quebec, Canada, from November 1997 to May 1998. Prenatal questionnaires were linked with birth certificates. Theoretical models explaining pregnancy length and fetal growth were developed and tested, using path analysis. In order to reduce the number of variables from the questionnaire, a principal component analysis was performed, and the three most important new dimensions were retained as explanatory variables in the final models. Data were available for 1602 singleton pregnancies. The biophysical score, covering both maternal age and the pre-pregnancy body mass index, was the only variable statistically associated with pregnancy length. Smoking, obstetric history, maternal health and biophysical indices were direct predictors of fetal growth. Perceived stress, social support and self-esteem were not directly related to pregnancy outcomes, but were determinants of smoking and the above-mentioned biomedical variables. More studies are needed to identify the mechanisms by which adverse psychosocial factors are translated into adverse biological effects.

In Mexico, 20% of the annual births are presented in women younger than 20 years old. Pregnancy in adolescents puts at risk mother and child health. This risk is major while the woman is younger, especially when the social and economic conditions are not favorable, which is decisive in later psychosocial development. It has been pointed out that the youths with low education, with minor academic and laboral expectations, with low self-esteem and assertiveness, tend to begin early their active sexual life, to use less frequently contraceptives, and in the case of younger women, to be pregnant, with the risk of abortion because they cannot to make the best decision. It is important to take into account the social context and the special characteristics of the family to understand situation of adolescent at risk of pregnancy.

To describe patterns of leisure time physical activity during pregnancy in relation to pre-pregnancy leisure time physical activity, socio-demographic characteristics, fertility history, and lifestyle factors. 4,718 nulliparous with singleton pregnancy and intended spontaneous vaginal delivery were included in the study at gestational week 33 from May 2004 to July 2005. Information was provided by self-administered questionnaires. Leisure time physical activity was categorised into four categories: competitive sport, moderate-to-heavy, light or sedentary. In this population of nulliparous women, 4% participated in competitive sport, 25% in moderate-to-heavy activities, 66% in light activities, and 5% in sedentary activities in the year prior to pregnancy. Physical activity before pregnancy was statistically significantly associated with age, pre-pregnancy BMI, chronic diseases, number of years at school, and smoking habits. The proportion of women who took part in competitive sports, and moderate-to-heavy activities decreased over the three trimesters of pregnancy. The proportion of women with light physical activity was stable during pregnancy while the proportion of women with sedentary activity increased from 6% to 29%. During the third trimester women performing competitive sports or moderate-to-heavy activities before pregnancy continued to have a higher level of physical activity than women with light activities or sedentary activities before pregnancy. In general the intensity and time spent on exercise decreased during pregnancy. Women with the highest level of exercise prior to pregnancy continued to be the most active during pregnancy. Among women with sedentary activities before pregnancy one-fourth changed to light activity during pregnancy.

Women who drink light-to-moderately during pregnancy have been observed to have lower risk of unfavourable pregnancy outcomes than abstainers. This has been suggested to be a result of bias. In a pooled sample, including 193 747 live-born singletons from nine European cohorts, we examined...... alcohol. This decreased to 39% in 2000–2004, and 14% in 2005–2011. Before 2000, every additional drink was associated with reduced mean birth weight, whereas in 2005–2011, the mean birth weight increased with increasing intake. The period-specific associations between low-to-moderate drinking and birth...

To evaluate the advantages and disadvantages of being underweight before pregnancy. Cohort study of a large population-based dataset of singleton births was used to compare maternal and neonatal outcomes of pre-gravid underweight body mass index (BMI 4,000 g, less cesarean births and a lower incidence of gestational diabetes and hypertensive disorders. A tradeoff exists between the advantages of being lean before pregnancy in terms of less maternal morbidity in return for gaining a more advanced gestational age and higher birth weight. © 2016 S.

There is a direct link between healthy mothers and healthy infants. Exercise and appropriate nutrition are important contributors to maternal physical and psychological health. The benefits and potential risks of exercise during pregnancy have gained even more attention, with a number of studies having been published after the 2002 American College of Obstetrics and Gynecologists guidelines. A review of the literature was conducted by using PubMed, Scopus, and Embase to assess the literature regarding the benefits of exercise during pregnancy. The search revealed 219 publications, which the authors then narrowed to 125 publications. The purpose of this review is to briefly summarize the known benefits of exercise to the mother, fetus, and newborn. Copyright © 2012 American Academy of Physical Medicine and Rehabilitation.

Full Text Available Singleton-Merten syndrome (SMS is an autosomal dominant, multi-system innate immune disorder characterized by early and severe aortic and valvular calcification, dental and skeletal abnormalities, psoriasis, glaucoma, and other varying clinical findings. Recently we identified a specific gain-of-function mutation in IFIH1, interferon induced with helicase C domain 1, segregated with this disease. SMS disease without hallmark dental anomalies, termed atypical SMS, has recently been reported caused by variants in DDX58, DEXD/H-box helicase 58. IFIH1 and DDX58 encode retinoic acid-inducible gene I (RIG-I-like receptors family members melanoma differentiation-associated gene 5 and RIG-I, respectively. These cytosolic pattern recognition receptors function in viral RNA detection initiating an innate immune response through independent pathways that promote type I and type III interferon expression and proinflammatory cytokines. In this review, we focus on SMS as an innate immune disorder summarizing clinical features, molecular aspects of the pathogenetic pathway and discussing underlying mechanisms of the disease.

Pregnancy has both short-term effects and long-term consequences. For women who have an autoimmune disease and subsequently become pregnant, pregnancy can induce amelioration of the mother’s disease, such as in rheumatoid arthritis, while exacerbating or having no effect on other autoimmune diseases like systemic lupus erythematosus. That pregnancy also leaves a long-term legacy has recently become apparent by the discovery that bi-directional cell trafficking results in persistence of fetal cells in the mother and of maternal cells in her offspring for decades after birth. The long-term persistence of a small number of cells (or DNA) from a genetically disparate individual is referred to as microchimerism. While microchimerism is common in healthy individuals and is likely to have health benefits, microchimerism has been implicated in some autoimmune diseases such as systemic sclerosis. In this paper, we will first discuss short-term effects of pregnancy on women with autoimmune disease. Pregnancy-associated changes will be reviewed for selected autoimmune diseases including rheumatoid arthritis, systemic lupus erythematosus and autoimmune thyroid disease. The pregnancy-induced amelioration of rheumatoid arthritis presents a window of opportunity for insights into both immunological mechanisms of fetal-maternal tolerance and pathogenic mechanisms in autoimmunity. A mechanistic hypothesis for the pregnancy-induced amelioration of rheumatoid arthritis will be described. We will then discuss the legacy of maternal-fetal cell transfer from the perspective of autoimmune diseases. Fetal and maternal microchimerism will be reviewed with a focus on systemic sclerosis (scleroderma), autoimmune thyroid disease, neonatal lupus and type I diabetes mellitus. PMID:18716941

To develop effective health promotional and preventive prenatal programs, it is important to understand perceived barriers to leisure-time physical activity during pregnancy, including exercise and sport participation. The aims of the present study was 1) to assess the effect of prenatal lifestyle intervention on the perceived barrier to leisure-time physical activity during pregnancy and the first year after delivery and 2) identify the most important perceived barriers to leisure-time physical activity at multiple time points during and after pregnancy. This secondary analysis was part of the Norwegian Fit for Delivery study, a combined lifestyle intervention evaluated in a blinded, randomized controlled trial. Healthy, nulliparous women with singleton pregnancy of ≤20 gestational weeks, age ≥ 18 years and body mass index ≥19 kg/m 2 were recruited via healthcare clinics in southern Norway, including urban and rural settings. Participants were randomized to either twice-weekly supervised exercise sessions and nutritional counselling (n = 303) or standard prenatal care (n = 303). The principal analysis was based on the participants who completed the standardized questionnaire assessing their perceived barriers to leisure-time physical activity at inclusion (gestational week 16, n = 589) and following intervention (gestational week 36, n = 509), as well as six months (n = 470) and 12 months (n = 424) postpartum. Following intervention (gestation week 35.4 ± 1.0), a significant between-group difference in perceived barriers to leisure-time physical activity was found with respect to time constraints: "... I do not have the time" (intervention: 22 vs. control: 38, p = 0.030), mother-child safety concerns: "... afraid to harm the baby" (intervention: 8 vs. control: 25, p = 0.002) and self-efficacy: "... I do not believe/think that I can do it" (intervention: 3 vs. control: 10, p = 0.050). No positive effect was seen
Full Text Available Healthy diet in pregnancy should guarantee proper fetal growth and development, maintain (and promote maternal health and enable lactation. Nutritional counseling and interventions need to be an integral part of antenatal care and continue during pregnancy in order to reduce the risk of maternal, fetal and neonatal complications, as well as the short- and long-term adverse outcomes. Adverse pregnancy outcomes are more common in women who begin the gestation as undernourished or obese in comparison to pregnant women whose weight is within normal ranges. Increased nutritional and energy needs in pregnancy are met through numerous metabolic adaptations; pregnancy is successfully achieved within wide range of variations in energy supply and weight gain. However, if nutrient restriction exceeds the limits of adaptive responses, evidence indicates that fetus will develop the alternative metabolic competence that might emerge as a disease (type 2 diabetes, hypertension, coronary heart disease and stroke in adult life.

To describe the needs and evidence-based practice specific to care of the pregnant adolescent in Canada, including special populations. Healthy pregnancies for adolescent women in Canada, with culturally sensitive and age-appropriate care to ensure the best possible outcomes for these young women and their infants and young families, and to reduce repeat pregnancy rates. Published literature was retrieved through searches of PubMed and The Cochrane Library on May 23, 2012 using appropriate controlled vocabulary (e.g., Pregnancy in Adolescence) and key words (e.g., pregnancy, teen, youth). Results were restricted to systematic reviews, randomized control trials/controlled clinical trials, and observational studies. Results were limited to English or French language materials published in or after 1990. Searches were updated on a regular basis and incorporated in the guideline to July 6, 2013. Grey (unpublished) literature was identified through searching the websites of health technology assessment and health technology-related agencies, national and international medical specialty societies, and clinical practice guideline collections. The quality of evidence in this document was rated using the criteria described in the Report of the Canadian Task Force on Preventive Health Care (Table 1). BENEFITS/HARMS/COSTS: These guidelines are designed to help practitioners caring for adolescent women during pregnancy in Canada and allow them to take the best care of these young women in a manner appropriate for their age, cultural backgrounds, and risk profiles. 1. Health care providers should adapt their prenatal care for adolescents and offer multidisciplinary care that is easily accessible to the adolescent early in the pregnancy, recognizing that adolescents often present to care later than their adult counterparts. A model that provides an opportunity to address all of these needs at one site may be the preferred model of care for pregnant adolescents. (II-1A) 2. Health

The live, attenuated, tetravalent dengue vaccine (CYD-TDV) is licensed in several endemic countries and contraindicated during pregnancy. Inadvertent vaccination during pregnancy may occur during clinical trials that include women of childbearing age. The potential risk associated with dengue vaccination in pregnancy remains unknown. We describe pregnancy outcomes following inadvertent dengue vaccination in pregnancy from CYD-TDV trial data. Data were collected from trials conducted as part of the CYD-TDV clinical development. Women who received CYD-TDV or placebo during the pre-specified pregnancy risk window (from 30 days before the date of their last menstrual period to end of pregnancy) were considered as exposed; pregnancies occurring in non-risk periods during the trials were considered to be non-exposed. Pregnancy losses were defined as abortion (spontaneous or unspecified), death in utero, and stillbirth. 615 pregnancies were reported from 19 CYD-TDV trials: 404 in the CYD-TDV arm, and 211 in the placebo arm. Exposure could not be determined for 7 pregnancies (5, CYD-TDV; 2, placebo). In the CYD-TDV arm, 58 pregnancies were considered as exposed. Most of these (n = 47, 81%) had healthy live births; 6 (10.3%) had pregnancy losses; 3 underwent elective termination and 2 had unknown outcome. In the placebo group, 30 pregnancies were considered exposed. Most of these (n = 25, 83%) had healthy births; 4 (13.3%) had pregnancy losses; and 1 had elective termination. Among non-exposed pregnancies, most resulted in healthy live births; 23/341 (6.7%) in the CYD-TDV group and 17/179 (9.5%) in the placebo group had pregnancy losses. Most reported pregnancy losses were in women considered high-risk for adverse pregnancy outcome, primarily due to young age. In the small dataset assessed, no evidence of increased adverse pregnancy outcomes has been identified from inadvertent immunization of women in early pregnancy with CYD-TDV compared with the control group

Full Text Available Hormonal disorders are one of the main known causes of miscarriage and preterm birth in multiple pregnancies resulting from assisted reproductive technology (ART. Progesterone and the number of its receptors play an important role in the preservation and prolongation of pregnancy and it is the pressing issue of our time. The study of placentas, as the main site of synthesis of progesterone, has high informative potential and it is the most important diagnostic object, and information received by its research is essential for the full conclusion on the causes, mechanisms, close and long-term effects of multiple pregnancy pathology. Aim. The aim of our study was to investigate immunohistochemical features of placentas from women with dichorionic diamniotic twin pregnancies in spontaneous fertilization and after use of assisted reproductive technology (ART. Methods and results. According to this goal we examined 94 women, 44 of whom had multiple pregnancies due to ART, 42 with separate multiple pregnancy and 38 women with a singleton pregnancy. We carried out clinical and statistical analysis of the course of pregnancy and childbirth in the studied groups. During the study it was found that multiple pregnancies due to assisted reproduction belong to the high risk of gestation, at which premature births occur much more frequently than in singleton pregnancies. We were the first to carry out the immunohistochemical study of placentas in which the highest expression of progesterone receptors in the nuclei of cells of decidua (45% related to the parent structure of the placenta from women with multiple pregnancies caused by ART is found. It is also found that with increasing gestational age, there has been a significant decrease in the expression of the activity of progesterone receptors (from 45 to 2.5%, regardless of the method of conception and the number of fetuses. Conclusions. The results of the study point to the definitive link of structures of

BACKGROUND: Recent data suggest that the chance of successfully maintaining a pregnancy may be influenced by the sex of previously born children. We explored a possible relation between sex of the first-born infant and the risk of preterm birth in the second pregnancy. METHODS: Using data from...... the National Medical Birth Registries in Denmark 1980-2004 and Sweden 1980-2001, we selected all women whose first and second births were singleton and who had information on sex of first-born infant and gestational age for the second (Denmark, n = 393,686; Sweden, n = 603,282). Cox proportional hazards...... regression analysis was used to estimate the hazard ratio of preterm birth in the second pregnancy according to the sex of the first-born infant. RESULTS: Compared with women whose first baby was a girl, women with boys had an increased risk of preterm birth in a second pregnancy (hazard ratio = 1.10 [95...
OBJECTIVE: Previous studies on weight gain in pregnancy suggested that maternal weight on average increased by 0.5-2.0 kg in the first trimester of pregnancy. This study examined whether mean maternal weight or body composition changes in the first trimester of pregnancy. DESIGN: Prospective observational study. POPULATION: We studied 1,000 Caucasian women booking for antenatal care in the first trimester of pregnancy. SETTING: Large university teaching hospital. METHODS: Maternal height and weight were measured digitally in a standardized way and Body Mass Index (BMI) was calculated. Maternal body composition was measured using segmental multifrequency Bioelectrical Impedance Analysis (BIA). Sonographic examination confirmed the gestational age and a normal ongoing singleton pregnancy in all subjects. MAIN OUTCOME MEASURES: Maternal weight, maternal body composition. RESULTS: The mean BMI was 25.7 kg\\/m(2) and 19.0% of the women were in the obese category (> or =30.0 kg\\/m(2)). Cross-sectional analysis by gestational age showed that there was no change in mean maternal weight, BMI, total body water, fat mass, fat-free mass or bone mass before 14 weeks gestation. CONCLUSIONS: Contrary to previous reports, mean maternal weight and mean body composition values remain unchanged in the first trimester of pregnancy. This has implications for guidelines on maternal weight gain during pregnancy. We also recommend that calculation of BMI in pregnancy and gestational weight gain should be based on accurate early pregnancy measurements, and not on self-reported or prepregnancy measurements.

Twenty-eight twin pregnancies were monitored by serial ultrasonic cephalometry from 30 or 31 weeks' gestation. The rates of growth of the individual twins as determined by biparietal diameters were similar in 11 cases (39%) and divergent in 17 (61%). When the rates of growth were divergent, the lesser rate was always below the mean for singleton pregnancies, and the incidence of small-for-gestational-age babies was 18 of 34 (53%). It was apparent that the greater the difference in biparietal diameters within the 2 weeks preceding delivery, the higher the risk of a small-for-gestation-age baby being delivered. No comment could be made on the growth rate prior to 28 weeks except that at diagnosis there was little or no difference in biparietal diameters.
Full Text Available Progress in the fields of fetal cardiology and fetal surgery have been seen not only in singleton pregnancies but also in multiple pregnancies. Proper interpretation of prenatal echocardiography is critical to clinical decision making, family counseling and perinatal management for obstetricians, maternal fetal medicine specialists, neonatologists and pediatric cardiologists. Fetal echocardiography is one of the most challenging and time-consuming prenatal examinations to perform, especially in multiple gestations. Performing just the basic fetal exam in twin gestations may take an hour or more. Thus, it is not practical to perform this exam in all cases of multiple gestations. Therefore our review and recommendations are related to fetal echocardiography in twin gestation.

To determine the relationship between type of infant feeding and mental and psychomotor development at age 18 months. A follow-up study of children born to primigravidae living in Dundee and booked into antenatal clinics in the City of Dundee (Local Authority District) from 1 May 1985 to 30 April 1986. The study population was 846 first born singletons, of whom 592 attended for developmental assessment at age 18 months. The main outcome measures were the Bayley Scales of Infant Mental and Motor Development. Higher mental development was significantly related to breast feeding on discharge from hospital and according to the health visitors' notes at about 2 weeks after discharge after allowing for partner's social class, mother's education, height, alcohol and cigarette consumption; placental weight and the child's sex, birth weight and gestational age at birth. After adjustment for statistically significant variables, the difference in Bayley mental development index between breast and bottle fed infants was between 3.7 and 5.7 units depending on the source of feeding data. No differences were found for psychomotor development or behaviour. The study provides further evidence of a robust statistical association between type of feeding and child intelligence. However, the literature is replete with suggestions for potential confounding variables which offer alternative causal explanations. To unravel what is an important clinical and public health question, further research should concentrate on randomized trials of supplemented formula feeds for children of mothers opting for bottle feeding and on epidemiological studies designed to disentangle the relation between method of feeding, parental intelligence and social environment.

Children born at term with low birth weight (LBW) are regarded growth restricted and are at particular risk of adverse health outcomes requiring a high degree of parental participation in the day-to-day care. This study examined whether their increased risk of special health care needs compared to other children may influence mothers' opportunities for participation in the labor market at different times after delivery. Data from 32,938 participants in the population-based Norwegian Mother and Child Cohort Study with singleton children born at term in 2004-2006 were linked to national registers in order to investigate the mothers' employment status when their children were 1-3 years in 2007 and 4-6 years in 2010. Children weighing less than two standard deviations below the gender-specific mean were defined as LBW children. Although not significantly different from mothers of children in the normal weight range, mothers of LBW children had the overall highest level of non-employment when the children were 1-3 years. At child age 4-6 years on the other hand, LBW was associated with an increased risk of non-employment (RR 1.39: 95 % CI 1.11-1.75) also after adjustment for factors associated with employment in general. In accordance with employment trends in the general population, our findings show that while mothers of normal birth weight children re-enter the labor market as their children grow older, mothers of LBW children born at term participate to a lesser extent in paid employment and remain at levels similar to those of mothers with younger children.

Vasculitis is more often a disease of women beyond their reproductive years, leaving the challenges of pregnancy management difficult to study. Pregnancy complications, including pregnancy loss and preterm birth, are higher among women with all forms of vasculitis. It seems that controlling the disease before pregnancy may improve the chances of pregnancy success. Many medications used for vasculitis are considered low risk in pregnancy, including prednisone, colchicine, azathioprine, and tumor necrosis factor inhibitors. Cyclophosphamide, methotrexate, and mycophenolate mofetil should be avoided in pregnancy. Controlling disease with low-risk medications may allow women with vasculitis to have the pregnancies they desire. Copyright © 2017 Elsevier Inc. All rights reserved.

Outcome of pregnancy was reported by 99 patients who were cured of childhood Wilms' tumor at seven pediatric cancer centers during 1931 to 1979. These patients carried or sired 191 singleton pregnancies of at least 20 weeks in duration. Among the 114 pregnancies in women who had received abdominal radiotherapy for Wilms' tumor, an adverse outcome occurred in 34 (30%). There were 17 perinatal deaths (five in premature low-birth-weight infants) and 17 other low-birth-weight infants. Compared with white women in the United States, the irradiated women had an increased perinatal mortality rate (relative risk, 7.9) and an excess of low-birth-weight infants (relative risk, 4.0). In contrast, an adverse outcome was found in two (3%) of the 77 pregnancies in nonirradiated female patients with Wilms' tumor and wives of male patients. The high risk of adverse pregnancy outcome should be considered in the counseling and prenatal care of women who have received abdominal radiotherapy for Wilms' tumor

More women are entering pregnancy with pre-existing diabetes. Disease severity, glycaemic control, and predictors of pregnancy complications may differ by race/ethnicity or educational attainment, leading to differences in adverse pregnancy outcomes. We used linked New York City hospital record and birth certificate data for 6291 singleton births among women with pre-existing diabetes between 1995 and 2003. We defined maternal race/ethnicity as non-Hispanic white, non-Hispanic black, Hispanic, South Asian, and East Asian, and education level as 12 years. Our outcomes were pre-eclampsia, preterm birth (PTB) (pregnancy complications. Non-Hispanic black, Hispanic, and South Asian women with pre-existing diabetes may benefit from targeted interventions to improve pregnancy outcomes. © 2013 The Authors.

Full text: In this report there will be presented the effects of ionizing radiation at the fetus and the necessary radioprotection. The biological results on the fetus, caused by the irradiation, depend on the dose of ionizing radiation that it receives and the phase of its evolution. The imminent effects of the irradiation can cause the fetus death, abnormalities and mental retardation, which are the result of overdose. The effects are carcinogenesis and leukemia, which are relative to the acceptable irradiating dose at the fetus and accounts about 0,015 % per 1 mSv. The effects of ionizing radiation depend on the phase of the fetus evolution: 1 st phase (1 st - 2 nd week): presence of low danger; 2 nd phase (3 rd - 8 th week): for doses >100 mSv there is the possibility of dysplasia; 3 rd phase (8 th week - birth): this phase concerns the results with a percentage 0,015 % per 1 mSv. We always must follow some rules of radioprotection and especially at Classical radiation use of necessary protocols (low dose), at Nuclear Medicine use of the right radioisotope and the relative field of irradiation for the protection of the adjacent healthy tissues and at Radiotherapy extreme caution is required regarding the dose and the treatment. In any case, it is forbidden to end a pregnancy when the pregnant undergoes medical exams, in which the uterus is in the beam of irradiation. The radiographer must always discuss the possibility of pregnancy. (author)

Full Text Available Pregnancy gingivitis is an acute form of gingivitis that affects pregnant women, with a prevalence of 30%, possibly ranging up to 100%. Sometimes, pregnancy gingivitis shows a tendency toward a localized hyperplasia called gingival pyogenic granuloma. Pregnancy tumor is a benign gingival hyperplasia with the gingiva as the most commonly involved site, but rarely it involves almost the entire gingiva. A 22-year-old woman was referred to our clinic with a chief complaint of gingival swelling that had lasted for 2 days. The lesions progressed rapidly and extensively, and almost all the gingiva was involved a week later. Generalized erythema, edema, hyperplasia, a hemorrhagic tendency, and several typical hemangiomatous masses were noted. Pregnancy was denied by the patient at the first and second visits, but was confirmed 2 weeks after the primary visit. The patient was given oral hygiene instructions. She recovered well, and the mass gradually regressed and had disappeared completely at the end of 12 weeks of pregnancy, without recurrence. The gingival lesions were finally diagnosed as multiple gingival pregnancy tumors. The patient delivered a healthy infant. An extensive and rapid growth of gingival pregnancy tumors during the early first month of pregnancy is a rare occurrence that is not familiar to dentists, gynecologists, and obstetricians. Those practitioners engaged in oral medicine and periodontology, primary care obstetrics, and gynecology should be aware of such gingival lesions to avoid misdiagnosis and overtreatment.

To review the evidence and provide recommendations for the counselling and management of obese parturients. Outcomes evaluated include the impact of maternal obesity on the provision of antenatal and intrapartum care, maternal morbidity and mortality, and perinatal morbidity and mortality. Literature was retrieved through searches of Statistics Canada, Medline, and The Cochrane Library on the impact of obesity in pregnancy on antepartum and intrapartum care, maternal morbidity and mortality, obstetrical anaesthesia, and perinatal morbidity and mortality. Results were restricted to systematic reviews, randomized controlled trials/controlled clinical trials, and observational studies. There were no date or language restrictions. Searches were updated on a regular basis and incorporated in the guideline to April 2009. Grey (unpublished) literature was identified through searching the websites of health technology assessment and health technology assessment-related agencies, clinical practice guideline collections, clinical trial registries, and national and international medical specialty societies. The evidence obtained was reviewed and evaluated by the Maternal Fetal Medicine and Clinical Practice Obstetric Committees of the SOGC under the leadership of the principal authors, and recommendations were made according to guidelines developed by the Canadian Task Force on Preventive Health Care. Implementation of the recommendations in this guideline should increase recognition of the issues clinicians need to be aware of when managing obese women in pregnancy, improve communication and consultation amongst the obstetrical care team, and encourage federal and provincial agencies to educate Canadians about the values of entering pregnancy with as healthy a weight as possible. 1.

Background Maternal overweight and obesity is one of the most common high-risk obstetric conditions associated with adverse birth outcomes. Smaller studies have suggested that pre-pregnancy body mass index (BMI) is associated with postpartum weight retention. Objective The primary objective of this study was to examine the association between pre-pregnancy BMI status and maternal weight retention. Study design We conducted a population-based retrospective cohort study using Washington State birth certificate data from 2003-2013. We included women who had two sequential births during this time period, with the second birth occurring within 18-36 months of the first singleton delivery date. BMI before a women's first pregnancy ("pre-pregnancy BMI") was categorized as normal (18.5-24.9 kg/m 2 ) and overweight/obese (25-40 kg/m 2 ). Women were classified as having returned to first pre-pregnancy BMI if their BMI before their second pregnancy was no more than 1 kg/m 2 more compared to their BMI before their first pregnancy. Analyses were stratified by gestational weight gain during the first pregnancy (below, met, exceeded recommended gestational weight gain). Results A total of 49,132 mothers were included in the study. Among women who met their recommended gestational weight gain, compared to mothers with a normal BMI, obese/overweight mothers were less likely to return to their pre-pregnancy BMI (76.5 vs 72.3%; RR Obese/Overweight = 0.88; 95% CI: 0.85-0.92). A similar pattern was observed among women who exceeded their recommended gestational weight gain (62.6 vs 53.2%; RR Obese/Overweight = 0.79, 95% CI: 0.78-0.80). Conclusion Pre-pregnancy BMI in the overweight/obese range is associated with a decreased likelihood of returning to pre-pregnancy BMI. Further research to support women during and after their pregnancy to promote behavior changes that prevent excessive weight gain during pregnancy and weight retention after birth is needed.

Around the world, the incidence of multiple pregnancies reaches its peak in the Central African countries and often represents an increased risk of death for women and children because of higher rates of obstetrical complications and poor management skills in those countries. We sought to assess the association between twins and early neonatal mortality compared with singleton pregnancies. We also assessed the role of skilled birth attendant and mode of delivery on early neonatal mortality in twin pregnancies. We conducted a secondary analysis of individual level data from 60 nationally-representative Demographic and Health Surveys including 521 867 singleton and 14 312 twin births. We investigated the occurrence of deaths within the first week of life in twins compared to singletons and the effect of place and attendance at birth; also, the role of caesarean sections against vaginal births was examined, globally and after countries stratification per caesarean sections rates. A multi-level logistic regression was used accounting for homogeneity within country, and homogeneity within twin pairs. Early neonatal mortality among twins was significantly higher when compared to singleton neonates (adjusted odds ratio (aOR) 7.6; 95% confidence interval (CI) = 7.0-8.3) in these 60 countries. Early neonatal mortality was also higher among twins than singletons when adjusting for birth weight in a subgroup analysis of those countries with data on birth weight (n = 20; less than 20% of missing values) (aOR = 2.8; 95% CI = 2.2-3.5). For countries with high rates (>15%) of caesarean sections (CS), twins delivered vaginally in health facility had a statistically significant (aOR = 4.8; 95% CI = 2.4-9.4) increased risk of early neonatal mortality compared to twins delivered through caesarean sections. Home twin births without SBA was associated with increased mortality compared with delivering at home with SBA (aOR = 1.3; 95% CI = 1.0-1.8) and
Full Text Available Background: Pregnancy has a huge impact on the thyroid function in both healthy women and those that have thyroid dysfunction. The prevalence of thyroid dysfunction in pregnant women is relatively high. Objective: The objective of this review was to increase awareness and to provide a review on adverse effect of thyroid dysfunction including hyperthyroidism, hypothyroidism and thyroid autoimmune positivity on pregnancy outcomes. Materials and Methods: In this review, Medline, Embase and the Cochrane Library were searched with appropriate keywords for relevant English manuscript. We used a variety of studies, including randomized clinical trials, cohort (prospective and retrospective, case-control and case reports. Those studies on thyroid disorders among non-pregnant women and articles without adequate quality were excluded. Results: Overt hyperthyroidism and hypothyroidism has several adverse effects on pregnancy outcomes. Overt hyperthyroidism was associated with miscarriage, stillbirth, preterm delivery, intrauterine growth retardation, low birth weight, preeclampsia and fetal thyroid dysfunction. Overt hypothyroidism was associated with abortion, anemia, pregnancy-induced hypertension, preeclampsia, placental abruption, postpartum hemorrhage, premature birth, low birth weight, intrauterine fetal death, increased neonatal respiratory distress and infant neuro developmental dysfunction. However the adverse effect of subclinical hypothyroidism, and thyroid antibody positivity on pregnancy outcomes was not clear. While some studies demonstrated higher chance of placental abruption, preterm birth, miscarriage, gestational hypertension, fetal distress, severe preeclampsia and neonatal distress and diabetes in pregnant women with subclinical hypothyroidism or thyroid autoimmunity; the other ones have not reported these adverse effects. Conclusion: While the impacts of overt thyroid dysfunction on feto-maternal morbidities have been clearly

Obesity during pregnancy associate with maternal and perinatal risks that make the management of obesity, before and during pregnancy imperative. The best and most effective treatment of obesity in pregnancy is prevention. A healthy diet and regular exercise of pregnant woman is crucial for the normal development of pregnancy. Moreover every obese pregnant woman should be informed about the importance of calorie - intake regulation and weight reduction both before and after pregnancy. Additional therapeutic options are bariatric surgical procedures that a woman can have before pregnancy and anticoagulation therapy during pregnancy. This article attempts brief review on the current scientific knowledge that exists about the role of nutrition and physical activity in controlling the weight of obese pregnant women and its beneficial contribution to the health of both the mother and the newborn.

Full Text Available ABSTRACT: Introduction & Objective: Heterotopic pregnancy refers to the simultaneous occurrence of pregnancy intrauterine and outside of uterine corpus. It is most often manifested in women who have undergone artificial reproductive technology (ART but rarely occurs spontaneously. Heterotopic pregnancy still remains as a diagnostic and therapeutic challenge to practitioners. In this situation physicians should have high suspicion for diagnosis and intrauterine pregnancy protection. This study reported a case of ruptured spontaneous heterotopic pregnancy. Case: A 32 year-old woman with abdominal pain, nausea, vomiting and hypovolumic shock in 1386 referred to emergency department in Sanandaj hospital. She reported one previous cesarean section. On examination, the patient's abdomen was distended. She had generalized tenderness and rebound tenderness in abdomen. The ultrasonographic examination revealed large amount of fluid in pelvic and abdominal cavity with a large hematoma in right adnex but there was intrauterine pregnancy at 7 weeks with normal fetal heart activity. She underwent laparotomy for heterotopic pregnancy and ruptured tube with tubal pregnancy removed. Intrauterine pregnancy continued without problem and led to birth of a healthy female neonate. Conclusion: Physicians should be quite cautious of heterotopic pregnancy in woman at reproductive age. Any abnormality on physical examination or ultrasonography of a patient with intrauterine pregnancy and abdominal pain should heighten the clinician's suspicion for heterotopic pregnancy

Full Text Available Abstract Background The global obesity epidemic has led to increased attention on pregnancy, a period when women are at risk of gaining excessive weight. Excessive gestational weight gain is associated with numerous complications, for both mother and child. Though the problem is widespread, few studies have examined the effect of a lifestyle intervention in pregnancy designed to limit maternal weight gain. The Fit for Delivery study will explore the effectiveness of nutritional counseling coupled with exercise classes compared with standard prenatal care. The aims of the study are to examine the effect of the intervention on maternal weight gain, newborn birth weight, glucose regulation, complications of pregnancy and delivery, and maternal weight retention up to 12 months postpartum. Methods/design Fit for Delivery is a randomized controlled trial that will include 600 women expecting their first child. To be eligible, women must be 18 years of age or older, of less than 20 weeks gestational age, with a singleton pregnancy, and have a Body Mass Index (BMI ≥ 19 kg/m2. The women will be randomly allocated to either an intervention group or a control group. The control group will receive standard prenatal care. The intervention group will, in addition, receive nutritional counseling by phone, access to twice-weekly exercise sessions, and information on healthy eating and physical activity provided in pamphlets, evening meetings and an interactive website. Both groups will be monitored by weighing (including bioimpedance measurements of percent body fat, blood tests, self-report questionnaires and hospital record review. Discussion Weight gained in pregnancy affects the health of both the mother and her unborn child, and simple models for efficient intervention are in high demand. The Fit for Delivery intervention provides concrete advice on limiting energy intake and practical training in increasing physical activity. This lifestyle intervention

To determine whether fetuses affected by either chromosomal abnormalities or central nervous system (CNS) malformations are prone to complications during pregnancy and delivery. In this study, 320 singleton pregnancies with CNS malformations and 133 singleton pregnancies with chromosomal abnormaLities were compared with 149,112 singleton births without any known congenital anomalies. Exclusion criteria were: births with other congenital anomalies or malformations, pregnancies Lacking prenatal care and multiple pregnancies. Data was obtained using the computerized birth discharge records. The statistical analysis was performed with the SPSS package. There were no statistically significant differences in maternal age, ethnicity, uterine anomalies or parity. The ratio of general anesthesia was almost double in the study groups compared to the control group: 25% in the CNS malformation group (RR 2.617, CI 2.031-3.372) and 25.6% in the chromosomal abnormality group (RR 2.696, CI 1.825-3.982) and 11.3% in the control group (p malformation group, 20.3% in the chromosomal abnormaLity group and 12% in the control group. A logistic regression model that included previous CS, maLpresentation, non-reassuring fetal heart monitor (NRFHR) and presence of a malformation, concluded that the presence of a malformation was not an independent risk factor for CS. However, indirect causes, such as malpresentation (4.34 OR), were independently associated with the malformations. Fetuses affected by either CNS malformations or chromosomal abnormalities have a higher rate of pregnancy and delivery complications, including those which increase the risk of maternal morbidity and mortality.

Full Text Available Obesity is an emerging major health risk for women around the world. In this regard, little attention has been given to pregnancy, a moment of risk not only for major weight gain in these women, but also for macrosomia in their offspring. The objective of this study is to evaluate weight gain during pregnancy. Data pertains to a cohort of pregnant women attending general prenatal care clinics in six state capitals in Brazil, from 1991 to 1995. We studied women aged 20 years and over with singleton pregnancies and no diagnosis of diabetes outside pregnancy, enrolled at approximately 20 - 28 weeks of gestation. According to the Institute of Medicine criteria, 38% (95%CI: 36-40% of the women studied gained less and 29% (95%CI: 28-31% had more than the recommended total weight gain. These proportions vary according to pre-pregnancy nutritional status. Given the increasing epidemic of obesity, the high prevalence of overweight and obesity in Brazilian women prior to pregnancy, and the lack of achievement of recommended weight gain during pregnancy, more effective means of managing weight gain during pregnancy are necessary.

To compare the incidence of pregnancy-induced hypertension in patients with and without polycystic ovary disease (PCOD). We conducted a retrospective, case-control analysis of patients who achieved singleton pregnancies with human menopausal gonadotropin (hMG) therapy. Twenty-two PCOD patients were compared to 27 infertility patients without PCOD who were pregnant after hMG therapy. Non-PCOD patients received hMG for superovulation as part of superovulation/intrauterine insemination or in vitro fertilization/embryo transfer. PCOD patients were receiving hMG for simple ovulation induction. Pregnancy-induced hypertension was defined as late pregnancy blood pressure > 140/90 mm Hg on two readings six hours apart and return to normal blood pressure by four to six weeks postpartum. There were no differences between PCOD and non-PCOD patients with reference to age, body mass index, parity or other pregnancy-induced hypertension risk factors (i.e., chronic hypertension, diabetes or chronic renal disease). Pregnant PCOD patients had a much higher incidence of pregnancy-induced hypertension, 31.8% (7/22), versus non-PCOD patients, who only had a pregnancy-induced hypertension incidence of 3.7% (1/27) (P = .016, OR = 12.1, 95% CI = 1.3-566.8). PCOD patients are at very high risk of pregnancy-induced hypertension when pregnant after ovulation induction.

Objectives: To evaluate abortion and fetal congenital anomaly rates in women previously submitted to radioiodine therapy for differentiated thyroid carcinoma. Study design: A case-control study of 108 pregnant women, 48 cases whose pregnancies were evaluated after they had undergone radioiodine therapy for differentiated thyroid carcinoma, and the control group consisted of 60 healthy pregnant women. Results: Of a total of 66 pregnancies, 14 conceived within the first year, 51 one or more years after the last administration of 131 I, the medical record of one patient was not available. The interval between the last radioiodine therapy administration and conception ranged from 1 month to 10 years. There were a total of 4 miscarriages, 2 of them for unknown reasons. There was one case of congenital anomaly and two preterms birth. Nine women presented the following pregnancy events: placental insufficiency, hypertensive crisis, placental detachment, risk of miscarriage, preterm labour and four miscarriages. No statistical difference was observed between the studied and control groups. Conclusion: Radioiodine was followed by no significant increase in untoward effects in neither the pregnancy nor the offspring. (author)

Full Text Available Herpes simplex virus (HSV hepatitis by definition constitutes disseminated herpes simplex infection; it is rare, with only approximately 130 cases reported in the literature. Although HSV hepatitis typically occurs in immunocompromised hosts, pregnancy—especially the third trimester, has been identified as a risk factor for its development. This is likely because of the fact that humoral and cell-mediated immunity decrease throughout pregnancy and nadir in the third trimester with decreased T-cell counts and altered B/T lymphocyte ratios. Here, we report on a patient with HSV 2 hepatitis in a previously healthy 27-year-old woman in her 23rd week of pregnancy. She initially presented with nausea, vomiting, and abdominal pain and was found to have acute hepatocellular liver injury and a systemic inflammatory response syndrome. Broad-spectrum antibiotics and acyclovir were promptly initiated. Liver biopsy, serum DNA polymerase chain reaction (PCR as well as a labial ulcer culture and PCR were all positive for HSV 2. The patient recovered completely; however, her fetus did not survive. Review of the literature emphasizes that presentation with disseminated HSV infection typically occurs in the third trimester of pregnancy. This report emphasizes that abdominal pain combined with fever and hepatic dysfunction in pregnancy should prompt immediate consideration of the diagnosis of HSV hepatitis. Furthermore, given the high mortality rate and effective treatment, empiric treatment with acyclovir should be considered early in all potential cases.

Preimplantation genetic diagnosis (PGD) may pose risks to pregnancy outcome owing to the invasiveness of the biopsy procedure. This study compares outcome of singleton and twin clinical pregnancies conceived after fresh embryo transfers of PGD (n = 89) and matched intracytoplasmic sperm injection (ICSI) pregnancies (n = 166). The study was carried out in a single university affiliated centre. Because of the paucity of available data, a literature-based meta-analysis of studies comparing neonatal outcome of PGD and ICSI pregnancies was also conducted. In the retrospective cohort study, obstetric and neonatal outcome were available in 67 PGD and 118 ICSI pregnancies. Perinatal outcomes were comparable between PGD and ICSI pregnancies. Meta-analysis revealed similar outcomes, except for higher rate of low birth weight (<2500 g) neonates in ICSI twin pregnancies (RR 0.86, 95% CI 0.74 to 1.0). Mean birth weight, gestational age at birth, pre-term deliveries (<37 weeks) and malformations were all comparable. In this cohort study and subsequent meta-analysis, no association was found between PGD conceived pregnancies and risks of adverse neonatal or obstetrical outcomes compared with ICSI pregnancies.

Nearly half of US women begin pregnancy overweight or obese and more than half of overweight or obese pregnant women experience excessive gestational weight gain. Recent lifestyle intervention programmes have helped women avoid excessive weight gain during pregnancy, but helping women lose weight before pregnancy may be a more effective way to improve pregnancy outcomes. This study assessed women's attitudes towards pre-conception diet and weight management interventions. An anonymous survey was conducted in patients waiting in a health maintenance organization's obstetrics and primary care waiting rooms. It focused on attitudes towards participating in a pre-conception, lifestyle change programme. Eighty percent of the 126 women surveyed were pregnant or considering pregnancy within 5 years. Of the 126 respondents, 60 (48%) were overweight or obese. Of these, 96% rated healthy diet and healthy weight before pregnancy as very important or important and 77% favoured a healthy lifestyle programme (diet, weight management and physical activity) before becoming pregnant. Likewise, overweight or obese women reported being likely or highly likely to participate in specific intervention programme aspects such as keeping phone appointments (77%), using a programme website (70%) and keeping food and exercise records (63%). Survey results show that women in this population believe that adopting a healthy lifestyle and losing weight are important before pregnancy and that they are enthusiastic about programmes that will help them achieve those goals in preparation for pregnancy. © 2015 World Obesity.

Background: Season and vitamin D are indirect and direct correlates of ultraviolet (UV) radiation and are associated with pregnancy outcomes. Further to producing vitamin D, UV has positive effects on cardiovascular and immune health that may support a role for UV directly benefitting pregnancy. Objectives: To investigate the effects of UV exposure on pregnancy; specifically fetal growth, preterm birth and hypertensive complications. Methods: We conducted a systematic review of Medline, EMBASE, DoPHER, Global Health, ProQuest Public Health, AustHealth Informit, SCOPUS and Google Scholar to identify 537 citations, 8 of which are included in this review. This review was registered on PROSPERO and a. narrative synthesis is presented following PRISMA guidance. Results: All studies were observational and assessed at high risk of bias. Higher first trimester UV was associated with and improved fetal growth and increased hypertension in pregnancy. Interpretation is limited by study design and quality. Meta-analysis was precluded by the variety of outcomes and methods. Discussion: The low number of studies and risk of bias limit the validity of any conclusions. Environmental health methodological issues are discussed with consideration given to design and analytical improvements to further address this reproductive environmental health question. Conclusions: The evidence for UV having benefits for pregnancy hypertension and fetal growth is limited by the methodological approaches utilized. Future epidemiological efforts should focus on improving the methods of modeling and linking widely available environmental data to reproductive health outcomes. - Highlights: • Biologically plausible pathways support an association between ultraviolet radiation (UV) and pregnancy outcomes. • This study is the first systematic review of prevailing literature on the relationship between UV and singleton pregnancy outcomes. • It focuses on both substantive findings and the

The aim of this study was to assess the prevalence of female sexual dysfunction (FSD) during pregnancy in a sample of women from Egypt. This prospective cohort study was conducted among pregnant women who presented to the Obstetrics Outpatient Clinic - Suez Canal University Hospital for routine antenatal care between February 2012 and February 2013. The 451 women who completed the study attended during their first trimester with a singleton pregnancy and were in a stable relationship with their partners for the last 6 months. Sexual function was assessed using the Female Sexual Function Index (FSFI) questionnaire during the 4 weeks preceding pregnancy and then in each trimester during the antenatal visits. Prevalence of FSD during pregnancy was estimated to be 68.8%. According to the FSFI, scores of all domains and total score were significantly reduced during the whole period of pregnancy (average 22.5 ± 3.7) compared to the pre-conception period (30.5 ± 5.6). However, there was significant increase of all domains and total score during the second trimester (26.6 ± 3.9) in comparison to the first and third trimesters (22.4 ± 4.1 and 18.6 ± 3.8, respectively). Total FSFI score was found to be positively correlated to pre-conception total FSFI score. However, age, parity and duration of marriage were negatively correlated. FSD is a prevalent problem during pregnancy among Egyptian women. The magnitude of the problem is highest during the third trimester while the second trimester represents the peak of sexual function during pregnancy. © 2014 The Authors.

Immunological changes in and after a pregnancy may influence the onset of autoimmune diseases. An increased incidence of hyperthyroidism has been observed both in early pregnancy and postpartum, but it remains to be studied if the incidence of hypothyroidism varies in a similar way. Population-based cohort study using Danish nationwide registers. All women who gave birth to a singleton live-born child in Denmark from 1999 to 2008 (n = 403 958) were identified, and data on hospital diagnosis of hypothyroidism and redeemed prescriptions of thyroid hormone were extracted. The overall incidence rate (IR) of hypothyroidism during 1997-2010 and the IR in three-month intervals before, during and after the woman's first pregnancy in the study period were calculated and compared with the IR of hyperthyroidism. Altogether 5220 women were identified with onset of hypothyroidism from 1997 to 2010 (overall IR 92.3/100 000/year) and 1572 women developed hypothyroidism in the period from 2 years before to 2 years after birth of the first child in the study period. The incidence of hypothyroidism decreased during the pregnancy (incidence rate ratio (IRR) vs overall IR in the rest of the study period: first trimester: 0.89 (95% CI: 0.66-1.19), second trimester: 0.71 (0.52-0.97), third trimester: 0.29 (0.19-0.45)) and increased after birth with the highest level at 4-6 months postpartum (IRR 3.62 (2.85-4.60)). These are the first population-based data on the incidence of hypothyroidism in and around pregnancy. The incidence declined during pregnancy followed by a sharp increase postpartum. Notably, hypothyroidism as opposed to hyperthyroidism showed no early pregnancy increase. © 2016 European Society of Endocrinology.

Full Text Available A WOMAN OF REPRODUCTIVE AGE OFTEN HARBORS A SMALL NUMBER OF FOREIGN CELLS, REFERRED TO AS MICROCHIMERISM: a preexisting population of cells acquired during fetal life from her own mother, and newly acquired populations from her pregnancies. An intriguing question is whether the population of cells from her own mother can influence either maternal health during pregnancy and/or the next generation (grandchildren.Microchimerism from a woman's (i.e. proband's own mother (mother-of-the-proband, MP was studied in peripheral blood samples from women followed longitudinally during pregnancy who were confirmed to have uncomplicated obstetric outcomes. Women with preeclampsia were studied at the time of diagnosis and comparison made to women with healthy pregnancies matched for parity and gestational age. Participants and family members were HLA-genotyped for DRB1, DQA1, and DQB1 loci. An HLA polymorphism unique to the woman's mother was identified, and a panel of HLA-specific quantitative PCR assays was employed to identify and quantify microchimerism. Microchimerism from the MP was identified during normal, uncomplicated pregnancy, with a peak concentration in the third trimester. The likelihood of detection increased with advancing gestational age. For each advancing trimester, there was a 12.7-fold increase in the probability of detecting microchimerism relative to the prior trimester, 95% confidence intervals 3.2, 50.3, p<0.001. None of the women with preeclampsia, compared with 30% of matched healthy women, had microchimerism (p = 0.03.These results show that microchimerism from a woman's own mother is detectable in normal pregnancy and diminished in preeclampsia, supporting the previously unexplored hypothesis that MP microchimerism may be a marker reflecting healthy maternal adaptation to pregnancy.

Background. Lhermitte-Duclos disease or dysplastic gangliocytoma of the cerebellum is a rare disorder that can cause progressive mass effects to the structures occupying posterior fossa. Magnetic resonance imaging is a diagnostic modality of choice demonstrating characteristic non-enhancing gyriform pattern with the enlargement of cerebellar folia, hypointense on T1 and hyperintense on T2 weighted magnetic resonance images. Case report. The authors present a case of 37-year old woman with previously unknown Lhermitte-Duclos disease in the third trimester of pregnancy from the first signs of the disease to the first six months after delivery. Conclusions. More experience will be needed with this disease in pregnancy and post delivery period to recommend pregnancy for women with such condition. However, this case shows that a pregnant woman with Lhermitte-Duclos disease could reach full-term pregnancy and deliver a healthy child, without lifethreatening risk. (author)

Although the positive association between pre-pregnancy overweight and obesity with excessive gestational weight gain is well known, it is not clear how pre-pregnancy weight status is associated with gestational weight gain through maternal diet during pregnancy. This study aimed to examine the relationship between pre-pregnancy weight status and diet quality and maternal nutritional biomarkers during pregnancy. Our study included 795 U.S. pregnant women from the National Health and Nutrition Examination Survey, 2003-2012. Pre-pregnancy body mass index (BMI) was calculated based on self-reported pre-pregnancy weight and height. The cutoff points of pregnancy was assessed by the Healthy Eating Index (HEI)-2010 based on a 24-h recall. Multivariable logistic regressions were used to estimate the odds ratios (OR) and 95% confidence intervals (CI). For all pregnant women included in this study, the mean HEI-2010 (±standard error of the mean (SEM)) was 50.7 (±0.9). Women with obese pre-pregnancy BMI demonstrated significantly lower HEI-2010 compared to those with underweight and normal pre-pregnancy BMI, respectively. In an unadjusted model, women with pre-pregnancy obesity BMI had increased odds for being in the lowest tertile of HEI-2010 (33.4 ± 0.5) compared to those with underweight pre-pregnancy BMI (OR 5.0; 95% CI 2.2-11.4). The inverse association between pre-pregnancy overweight and obesity status and diet quality during pregnancy persisted even after we controlled for physical activity levels (adjusted OR (AOR) 3.8; 95% CI 1.2-11.7, AOR 5.4; 95% CI 2.0-14.5, respectively). Serum folate concentration (ng/mL) was significantly higher in underweight women compared to overweight women (23.4 ± 1.7 vs. 17.0 ± 0.8, p pregnancy weight status and diet quality and maternal nutritional biomarkers during pregnancy. Poor diet quality as measured by HEI-2010 was shown among overweight and obese women. Nutrition education and interventions need to be targeted to those

Two multigravidae aged 27 and 29 years, with previous uneventful pregnancies, second being psoriatic, reported at 24 and 28 weeks of pregnancies, with generalized pustular lesions. Laboratory findings, including serum calcium were normal. Ultrasonography showed normal fetal growth. Histopathology confirmed pustular psoriasis. Patients were put on cyclosporine 3 mg/ kg weight/ day after failure of an initial systemic steroid. Blood pressure, pulse, and fetal heart sounds were recorded every 12 hours, and ultrasonography and blood parameters, biweekly. Cyclosporine was tapered and stopped after delivery of two healthy babies at 38 weeks. We conclude that cyclosporine can be an option in the management of pustular psoriasis of pregnancy or psoriasis with pustulation in pregnancy.

Proteinuria and dilatation of the urinary tract are both relatively common in pregnancy, the latter with a spectrum of symptoms, from none to severe pain and infection. Proteinuria is a rare occurrence in acute obstructive nephropathy; it has been reported in pregnancy, where it may pose a challenging differential diagnosis with pre-eclampsia.The aim of the present study is to report on the incidence of proteinuria (≥ 0.3; ≥ 0.5 g/day) in association with symptomatic-severe urinary tract dilatation in pregnancy. Case series. Nephrological-Obstetric Unit dedicated to pregnancy and kidney diseases (January 2000-April 2011). database prospectively updated since the start of the Unit. Retrospective review of clinical charts identified as relevant on the database, by a nephrologist and an obstetrician. From January 2000 to April 2011, 262 pregnancies were referred. Urinary tract dilatation with or without infection was the main cause of referral in 26 cases (predominantly monolateral in 19 cases): 23 singletons, 1 lost to follow-up, 1 twin and 1 triplet. Patients were referred for urinary tract infection (15 cases) and/or renal pain (10 cases); 6 patients were treated by urologic interventions ("JJ" stenting). Among them, 11 singletons and 1 triple pregnancy developed proteinuria ≥ 0.3 g/day (46.1%). Proteinuria was ≥ 0.5 g/day in 6 singletons (23.1%). Proteinuria resolved after delivery in all cases. No patient developed hypertension; in none was an alternative cause of proteinuria evident. No significant demographic difference was observed in patients with renal dilatation who developed proteinuria versus those who did not. An association with the presence of "JJ" stenting was present (5/6 cases with proteinuria ≥ 0.5 g/day), which may reflect both severer obstruction and a role for vescico-ureteral reflux, induced by the stent. Symptomatic urinary tract dilatation may be associated with proteinuria in pregnancy. This association should be kept in mind in
Full Text Available Introduction. Recent epidemiological studies showed significantly higher incidence of perinatal complications in newborns and women after the use of assisted reproductive technologies (ART. Multiple pregnancies are more frequent after the use of ART. Singleton pregnancies following ART are more prone to preterm birth, low and very low birth weight (LBW and VLBW, small for gestational age (SGA and perinatal mortality. Objective. The aim of this study was to summarize the results of relevant articles and to evaluate whether the mode of conception is the determining factor for different pregnancy outcomes after assisted and natural conceptions. Methods. Eleven studies were included in this review. The following outcomes were observed: preterm and very preterm birth, SGA, LBW, VLBW, perinatal mortality, admission to neonatal intensive care unit (NICU, and Apgar score (As ≤7 at fifth minute. Qualitative analysis and quantitative assessment were performed. Results. For singletons, odds ratios were 1.794 (95% confidence interval 1.660-1.939 for preterm birth, 1.649 (1.301-2.089 for LBW, 1.265 (1.048-1.527 for SGA. Admission to NICU, As≤7 at fifth minute and perinatal mortality showed significantly different frequency after assisted conception. Summary of results for twin gestations showed no significant difference between ART and spontaneous conception for preterm birth (32-36 weeks, very preterm birth (<32 weeks, LBW and VLBW. Conclusion. Analyzed studies showed that infants from ART have significantly worse perinatal outcome compared with natural conception. More observational studies should be conducted in order to establish the exact mechanism leading to more frequent perinatal morbidity and mortality after the use of ART.

Pregnancy-induced hypertension (PIH) is mainly a vascular disease, probably caused by an imbalance between vasodilator and vasoconstrictor agents that results in generalized vasospasm and poor perfusion in many organs including the placenta. The current study was carried out on 55 women, fourty were pregnant and delivered by Elective Cesarean Section, 20 of them were normal healthy pregnant women with uncomplicated term singleton gestation and twenty with PIH. Fifteen were healthy non pregnant women (24-33 years old) served as control group. Active total serum ghrelin (pg/ml) and serum resistin (ng/ml) were measured using ELISA kits. At 25 weeks of gestational age, a highly significant decrease in ghrelin levels in the pregnant groups was detected compared to the non-pregnant group (p<0.0001). Comparing serum ghrelin levels between both pregnant groups showed that it was significantly higher in PIH pregnant women (p<0.05). However, serum resistin showed significant increase in pregnant women compared to the non pregnant. At time of delivery, ghrelin was found to be significantly higher in PIH patients (47.41±8.55 pg/ml) than in normal pregnant women (36.74±6.74 pg/ml). However no significant change was found in serum ghrelin and resistin concentrations in the umbilical cord blood between the previous 2 groups. A significant increase in the umbilical cord blood of ghrelin (41.82±6.30 pg/ml) was detected compared to maternal ghrelin (36.74±6.74 pg/ml) in normal pregnant women (p<0.05), but not in PIH pregnant women. However, a significant increase was detected in the umbilical cord blood of resistin in both normal and PIH pregnant groups compared to their corresponding maternal blood (p< 0.05). In normal pregnant women, serum ghrelin concentration was negatively correlated with both the systolic and diastolic blood pressure (systolic: p<0.05, diastolic: p<0.05). Furthermore, serum ghrelin concentration was also negatively correlated with the systolic blood

The theory of relational acoustic invariance claims that there are stable acoustic properties in speech signals that correspond to a phonological feature, and that the perception system utilizes these acoustic properties for stable perception of a phoneme. The present study examines whether such an invariance exists in native listeners' perception of Japanese singleton and geminate stops despite variability in speaking rate and word length, and whether this perception corresponds to production. Native Japanese listeners identified singleton and geminate stops in continua of 3- and 4-mora words spoken at different speaking rates. Results indicated that the perception boundary is well predicted by a linear function with two variables: durations of stop closure and the (C)V(C)CV portion (with the contrasting stops underlined) of the 3- and 4-mora words. In addition, these two variables were in a consistent relationship for both perception and production of words containing 2-4 moras. The results support the relational acoustic invariance theory. © 2015 S. Karger AG, Basel.

The aims of this study were to identify: (i) the proportion of women exceeding the caffeine intake guideline (>200 mg/day) during each trimester, accounting for point of pregnancy awareness; (ii) guideline adherence trajectories across pregnancy; (iii) maternal characteristics associated with trajectories; and (iv) association between adherence and growth restriction birth outcomes. Typical and maximal intake per consumption day for the first trimester (T1; pre- and post-pregnancy awareness), second (T2), and third trimester (T3) were recorded for a prospective cohort of pregnant Australian women with singleton births ( n = 1232). Birth outcomes were birth weight, small for gestational age, and head circumference. For each period, participants were classified as abstinent, within (≤200 mg), or in excess (>200 mg). Latent class growth analyses identified guideline adherence trajectories; regression analyses identified associations between adherence in each trimester and birth outcomes. The percentage of participants who reported caffeine use declined between T1 pre- and post-pregnancy awareness (89% to 68%), and increased in T2 and T3 (79% and 80%). Trajectories were: ' low consumption ' (22%): low probability of any use; ' within-guideline ' (70%): high probability of guideline adherence; and ' decreasing heavy use ' (8%): decreasing probability of excess use. The latter two groups were more likely to report alcohol and tobacco use, and less likely to report planning pregnancy and fertility problems. Exceeding the guideline T1 pre-pregnancy awareness was associated with lower birth weight after covariate control (b = -143.16, p = 0.011). Overall, high caffeine intake pre-pregnancy awareness occurs amongst a significant minority of women, and continued excess use post-pregnancy awareness is more common where pregnancy is unplanned. Excess caffeine consumption pre-pregnancy awareness may increase the risk for lower birth weight. Increasing awareness of the

To evaluate whether bone mineral density (BMD) changes in women engaged in active exercises during pregnancy would be different from non-exercising women. Consecutive patients with singleton pregnancies who were engaged in active exercise training during pregnancy were prospectively recruited over a period of 6 months. Quantitative USG measurements of the os calcis BMD were performed at 14-20 weeks and at 36-38 weeks. These patients were compared to a control cohort of non-exercising low-risk women. A total of 24 physically active women undergoing active physical training of over 10 h per week at 20 weeks gestation and beyond (mean 13.1 h, SD 3.3) were compared to 94 non-exercising low-risk women. A marginal fall in BMD of 0.015 g/cm(2) (SD 0.034) was demonstrable from early to late gestation in the exercising women, which was significantly lower than that of non-exercising women (0.041 g/cm(2); SD 0.042; p = 0.005). Logistic regression models confirmed that active exercises in pregnancy were significantly associated with the absence of or less BMD loss in pregnancy. In women actively engaged in physical training during pregnancy, the physiological fall in BMD during pregnancy was apparently less compared to those who did not regularly exercise.
Traditionally, the primary outcome of infertility trials has been a positive pregnancy test or a clinically recognized pregnancy. However, parents desire a healthy baby that grows up to be a healthy adult, rather than a positive pregnancy test. Too often results of infertility trials are lacking in crucial obstetric details. This is problematic because treatments for infertility have the capacity to increase the risk for a variety of adverse obstetric outcomes. This review will outline important obstetric variables that should be included when reporting infertility research. The rationale for including these data, precise definitions of the variables, and cost-effective strategies for obtaining these obstetric details will be highlighted.
