    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.

    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 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.

    The purpose of this study was to evaluate the contribution of amnioreduction to the management of singleton pregnancies that are complicated by symptomatic polyhydramnios. Retrospective review of all singleton pregnancies that received at least 1 amnioreduction for polyhydramnios from 2000-2012 at a single obstetric unit that provides a statewide service. The indications, procedural techniques, and pregnancy outcomes were evaluated. One hundred thirty-eight women with polyhydramnios (maximal vertical pocket [MVP], ≥8 cm) had 271 amnioreduction procedures during the study period. The median gestation at the first drain was 31.4 weeks (interquartile range, 28.4-34 weeks) and a median of 1 procedure (interquartile range, 1-2 procedures) was performed per pregnancy. Sixty-three women (45.6%) required >1 amnioreduction. The median volume removed per pregnancy was 2100 mL (interquartile range, 1500-4260 mL). The median duration from the first amnioreduction until delivery was 26 days (interquartile range, 15-52.5 days). There was no significant association between gestation at delivery and the volume per procedure or total volume that was removed. Earlier gestation at first drain was associated positively with earlier gestations at delivery. In 4.1% of amnioreduction procedures (11/271 procedures), there was an unplanned preterm birth within 48 hours. The median gestation at delivery was 36.4 weeks (interquartile range, 34-38 weeks). The final diagnoses were gastrointestinal malformations (21%), idiopathic polyhydramnios (20.3%), chromosomal anomaly (15.2%), syndromic condition (13.7%), and neurologic condition (8%). Amnioreduction has a useful role in the management of polyhydramnios in singleton pregnancies. Complications are uncommon, and delivery typically occurs near term. Copyright © 2014 Elsevier Inc.

    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.

    To establish sonographic reference ranges of the normal fetal thymus size between 17 and 38 weeks of gestational age (GA). The study was conducted between April 1 and December 31, 2013. Low-risk singleton pregnancies without obstetrical and medical complications at the GAs between 17 and 38 weeks were recruited for thymus measurement. The fetal thymus was identified on transabdominal sonography at the three-vessel view. Maximal transverse diameter, perimeter, and thymus/thoracic ratio were measured. The best-fit models in predicting thymic dimensions as a function of GA and biparietal diameter (BPD) were determined using regression analysis, and percentile charts for predicting thymic dimensions were constructed. A total of 296 singleton pregnancies were recruited in this study. Maximal transverse diameter, perimeter, and thymus/thoracic ratio increased throughout pregnancy. The regression equation for maximal transverse diameter of the thymus as a function of GA was as follows: Predicted mean thymus diameter (mm) = -25.904 + 2.476 × GA - 0.019 × GA 2 (r = 0.915; p thymus diameter (mm) = 1.428 + 0.044 × GA (r = 0.017; p < 0.001). Sonographic reference ranges of the normal fetal thymic dimensions between 17 and 38 weeks of GA have been established. © 2016 Wiley Periodicals, Inc.

    The umbilical coiling index (UCI) is a measure of the number of coils in the umbilical cord in relation to its length. Hypercoiled cords with a UCI of >0.3 coils/cm have been associated with adverse fetal and neonatal outcomes. The primary aim is to determine the accuracy of UCI measured on second trimester ultrasound in predicting UCI at birth. The secondary outcome is to investigate the association between hypercoiling of the umbilical cord on prenatal ultrasound and adverse maternal, fetal and neonatal outcomes. This was a prospective cohort study of uncomplicated singleton pregnancies. Seventy two patients were included in the study. UCI was measured in the second trimester ultrasound, and compared to UCI measured postnatally. Outcomes of patients with hypercoiled cords on ultrasound were compared to outcomes of patients with normocoiled cords. Our results failed to show a strong correlation between the UCI determined with ultrasound, and the UCI determined with examination of the umbilical cord after delivery. We also did not demonstrate that measurement of the UCI on second trimester ultrasound is able to predict adverse maternal, fetal or neonatal outcomes. This study suggests that measurement of the umbilical coiling index should not be part of routine second trimester sonography in patients with uncomplicated singleton pregnancies, with no other medical or surgical comorbidities.

    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.

    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 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

    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.

    To document the ambulatory arterial stiffness index (AASI) during pregnancy compared to three months after delivery in singleton and twin pregnancies. Descriptive study with a follow-up design. University hospital in Eastern Finland. 43 childbearing women; 32 with singleton and 11 with twin pregnancies. Ambulatory blood pressure measurements were conducted using a digital ambulatory blood pressure system. AASI was calculated as 1 minus the regression slope of diastolic on systolic blood pressures obtained from 24-hour monitoring. Arterial stiffness measured by AASI. In normotensive pregnant women, the 95th percentiles of AASI were 0.40 in singleton and 0.46 in twin pregnancies, respectively, implying arterial normality and high elasticity. There were no differences in AASI values between singleton and twin pregnancies and no changes were observed postpartum. After delivery, but not during pregnancy, AASI correlated negatively with nocturnal systolic and diastolic blood pressure reduction (dipping) (r=-0.536, p=0.001; r=-0.674, ptwin pregnancies had no detectable effects on AASI. However, pregnancy appeared to overcome the negative effects of low high-density lipoproteins, unfavorable dipping status and advanced maternal age on arterial stiffness, but not the effect caused by maternal body mass index. © 2011 The Authors Acta Obstetricia et Gynecologica Scandinavica© 2011 Nordic Federation of Societies of Obstetrics and Gynecology.

    The purpose of this study was to document cost that is associated with multiple births vs singleton births in the United States. This was a retrospective cohort study that used a claims database. Women 19-45 years old with live-born infants from 2005-2010 were identified. Infant deliveries were identified by International Classification of Diseases, 9th Revision, Clinical Modification diagnosis codes. The cost entailed all payment made by insurers and patients. For mothers, the cost included expenses from 27 weeks before delivery to 1 month after delivery. For infants, the cost contained all expenses until their first birthday. Adjusted cost was estimated by generalized linear models after adjustment for the potential confounding variables with a gamma distribution and a log link. The analysis included 437,924 eligible deliveries. Of them, 97.02% were singletons; 2.85% were twins, and 0.13% was triplets or more. Women with multiple pregnancies had higher systemic and localized comorbidities compared with women with singleton pregnancies (P < .0001). Twins and triplets or more were more likely to have stayed in a neonatal intensive care unit than were singletons (P < .0001). On average, adjusted total all-cause health care cost was $21,458 (95% confidence interval [CI], $21,302-21,614) per delivery with singletons, $104,831 (95% CI, $103,402-106,280) with twins, and $407,199 (95% CI, $384,984-430,695) with triplets or more. Pregnancies with the delivery of twins cost approximately 5 times as much when compared with singleton pregnancies; pregnancies with delivery of triplets or more cost nearly 20 times as much.

    The purpose of this study is to investigate whether abnormal hCG trends occur at a higher incidence among women conceiving singleton pregnancies following transfer of multiple (two or more) embryos (MET), as compared to those having a single embryo transfer (SET). Retrospective cohort study was performed of women who conceived singleton pregnancies following fresh or frozen autologous IVF/ICSI cycles with day 3 or day 5 embryo transfers between 2007 and 2014 at a single academic medical center. Cycles resulting in one gestational sac on ultrasound followed by singleton live birth beyond 24 weeks of gestation were included. Logistic regression models adjusted a priori for patient age at oocyte retrieval and day of embryo transfer were used to estimate the Odds Ratio of having an abnormal hCG rise (defined as a rise or hCG rises between the first and second measurements, compared to 2.7% (n = 17) of patients undergoing SET (OR 2.16, 95% CI 1.26-3.71). Among patients with initially abnormal hCG rises who had a third level checked (89%), three-quarters had normal hCG rises between the second and third measurements. Patients who deliver singletons following MET were more likely to have suboptimal initial hCG rises, potentially due to transient implantation of other non-viable embryo(s). While useful for counseling, these findings should not change standard management of abnormal hCG rises following IVF. The third hCG measurements may clarify pregnancy prognosis.

    Full Text Available Hyperreactio Luteinalis (HL is a benign self-limited pregnancy-related condition characterized by bilateral ovarian enlargement with multiple theca lutein cysts. It is commonly associated with gestational trophoblastic diseases and multiple pregnancy. We report a rare case of HL discovered accidentally during cesarean section (CS of a spontaneously conceived normal singleton pregnancy. CS was performed due to fetal malpresentation and previously scarred uterus, and delivered a healthy male neonate. Expectant management was performed to permit conservation of both ovaries without unnecessary surgical intervention. The condition resolved within 6 weeks postpartum without adding morbidity to the patient.

    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 compare levels of β-hCG and estradiol collected during the first trimester in singleton and twin pregnancies following assisted reproduction technologies (ART). We prospectively evaluated 50 singleton and 47 dichorionic twin pregnancies that eventually ended in live births. Patients were recruited from a single ART center with standard treatment protocols followed by fresh embryo transfers. Hormone measurements were performed within a narrow gestational age range and analyzed in a single laboratory thus minimizing inter- and intra-assay variability. We measured serum β-hCG at 13 days after embryo transfer as well as samples of β-hCG and estradiol at 8-9 weeks+6 days. No significant differences existed between singletons and twins in respect to demographic and cycle characteristics. β-hCG and estradiol were all significantly higher in twins (PhCG and estradiol in twins, pointing to the potential role of these placental hormones in early support of a twin pregnancy.

    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.

    Phenylketonuria (PKU) is the autosomal recessive deficiency of phenylalanine hydroxylase resulting in the accumulation of phenylalanine (Phe) in blood and in the brain. Phe restriction in a patient's diet is determined depending on the amount of Phe intake which allows for stable blood Phe levels within the therapeutic range of 120-360µmol/L. In clinical practice the empirical determination of Phe tolerance relies on frequent assessment of blood Phe concentrations in relation to Phe intake from food records. Untreated maternal PKU may lead to maternal PKU syndrome in offspring. The objective of the study was to compare Phe tolerance during the course of singleton and multiple pregnancies of PKU patients. Case subjects and methods: The cases reviewed included three sets of classical PKU-affected Polish women on a low-phenylalanine diet during the course of singleton and twin pregnancies and their PKU-unaffected newborns. All the patients were under regular supervision of a metabolic dietitian to stabilize blood Phe levels and determine Phe tolerance. Data on pregnancy weight gain, the gestational age when the diet initiated, the percent of Phe assessments 360 µmol/L, as well as offspring birth measurements were analyzed. The total increase in Phe tolerance and its pattern during the course of singleton and twin pregnancies differed remarkably in each patient. Three PKU women (Q383X/R408W, EX3DEL/EX3DEL, R281L/R408W) increased their Phe tolerance in singleton and twin pregnancies by 579%/468%, 674%/261%, and 427%/236%, respectively. During the last 10 weeks of singleton and twin pregnancy Phe tolerance showed an increase by 62%/149%, 33%/64%, and 37%/40%, respectively. The analysis of predictors for Phe tolerance showed that an individual's weight gain and the fetal weight gain as estimated from liveborn birth-weight data had no predictive capacity. Individual Phe tolerance in singleton pregnancies of PKU patients does not predict tolerance in twin pregnancy

    Full Text Available Abstract Background The increasing prevalence of obesity in young women is a major public health concern. These trends have a major impact on pregnancy outcomes in these women, which have been documented by several researchers. In a population based cohort study, using routinely collected data, this paper examines the effect of increasing Body Mass Index (BMI on pregnancy outcomes in nulliparous women delivering singleton babies. Methods This was a retrospective cohort study, based on all nulliparous women delivering singleton babies in Aberdeen between 1976 and 2005. Women were categorized into five groups – underweight (BMI 2, normal (BMI 20 – 24.9 Kg/m2 overweight (BMI 25 – 29.9 Kg/m2, obese (BMI 30 – 34.9 Kg/m2 and morbidly obese (BMI > 35 Kg/m2. Obstetric and perinatal outcomes were compared by univariate and multivariate analyses. Results In comparison with women of BMI 20 – 24.9, morbidly obese women faced the highest risk of pre-eclampsia {OR 7.2 (95% CI 4.7, 11.2} and underweight women the lowest {OR 0.6 (95% CI 0.5, 0.7}. Induced labour was highest in the morbidly obese {OR 1.8 (95% CI 1.3, 2.5} and lowest in underweight women {OR 0.8 (95% CI 0.8, 0.9}. Emergency Caesarean section rates were highest in the morbidly obese {OR 2.8 (95% CI 2.0, 3.9}, and comparable in women with normal and low BMI. Obese women were more likely to have postpartum haemorrhage {OR 1.5 (95% CI 1.3, 1.7} and preterm delivery ( 4,000 g was in the morbidly obese {OR 2.1 (95% CI 1.3, 3.2} and the lowest in underweight women {OR 0.5 (95% CI 0.4, 0.6}. Conclusion Increasing BMI is associated with increased incidence of pre-eclampsia, gestational hypertension, macrosomia, induction of labour and caesarean delivery; while underweight women had better pregnancy outcomes than women with normal BMI.

    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.

    Full Text Available Summary A retrospective study from November 2004 to May 2012, conducted at the Obstetric Clinic of Hospital das Clínicas, Faculdade de Medicina, Universidade de São Paulo (HC-FMUSP, which included 92 singleton pregnancies with prenatal diagnosis of trisomy of chromosome 21 (T21, 18, 13 (T13/18 and monosomy X (45X, with diagnosis performed until the 26th week of pregnancy. The aim of the study was to describe the frequency and to investigate predictors of spontaneous fetal death (FD. Diagnosis (T21, n=36; T13/18, n=25; 45X, n=31 was made at a mean gestational age of 18.3±3.7 weeks, through chorionic villus biopsy (n=22,24%, amniocentesis (n=66, 72% and cordocentesis (n=4, 4%. Major malformations were present in 45 (49%; with hydrops in 32 (35% fetuses, more frequently in 45X [n=24/31, 77% vs. T21 (n=6/36, 17% and T13/18 (n=2/25, 8%, p<0.001]. Specialized fetal echocardiography was performed in 60% (55/92. Of these, 60% (33/55 showed changes in heart morphology and/or function. Fetuses with T13/18 had a higher incidence of cardiac anomalies [60 vs. 25% (T21 and 29% (45X, p= 0.01]. FD occurred in 55 (60% gestations, being more frequent in 45X [n=26/31, 84% vs. T21 (n=13/36, 36% and T13/18 (n=16/25, 64%, p<0.01]. Stepwise analysis showed a correlation between hydrops and death in fetuses with T21 (LR= 4.29; 95CI=1.9-8.0, p<0.0001. In fetuses with 45X, the presence of echocardiographic abnormalities was associated with lower risk of FD (LR= 0.56; 95CI=0.27- 0.85, p=0.005. No predictive factors were identified in the T13/18 group. Intra- uterine lethality of aneuploid fetuses is high. Occurrence of hydrops increases risk of FD in pregnancies with T21. In pregnancies with 45X, the occurrence of echocardiographic changes reduces this risk.

    To characterise maternal demographics and ascertain whether clinically important differences exist in the intrapartum and neonatal outcomes associated with assisted reproductive technology (ART). A retrospective study was undertaken between January 2007 and December 2013 of all singleton pregnancies conceived via ART at a major tertiary unit in Brisbane, Australia. Intrapartum outcomes were mode of delivery and indication for emergency caesarean. Neonatal outcomes investigated were gestation at delivery, birth weight, Apgar scores, acidosis at birth, respiratory distress, need for resuscitation, admission to neonatal intensive care and stillbirth. There were 4733 (7.4%) ART and 59 277 (92.6%) spontaneous conception pregnancies. Women who conceived using ART were less likely to have a spontaneous vaginal delivery (odds ratio (OR) 0.60, 95% CI 0.57-0.64) and were more likely to require operative or assisted birth: elective caesarean (adjusted OR (aOR) 1.31, 95% CI 1.22-1.40), emergency caesarean (aOR 1.19, 95% CI 1.09-1.28), or instrumental delivery (aOR 1.45, 95% CI 1.32-1.58). Neonates who were conceived using ART were less likely to be born at term (aOR 0.64, 95% CI 0.58-0.71) and have lower birth weights. No differences were observed in rates of respiratory distress, admission to the neonatal intensive care unit, or stillbirth between the ART and spontaneous conception cohorts. The odds of neonatal acidosis (OR 0.71, 95% CI0.63-0.81) were lower in the ART cohort. Although higher rates of operative deliveries were seen for women who conceive using ART, neonatal outcomes were generally no different between the two cohorts. © 2017 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

    To determine whether there are any increases in pregnancy-related complications and adverse pregnancy outcomes in singleton pregnancies after assisted reproductive technology (ART) compared with those conceived naturally. Meta-analysis. University-affiliated teaching hospital. Singleton pregnancies conceived with ART and naturally. PubMed, Google Scholar, Cochrane Libraries and Chinese database were searched through March 2015 to identify studies that met pre-stated inclusion criteria. Either a fixed- or a random-effects model was used to calculate the overall combined risk estimates. Subgroup analysis was performed to explore potential heterogeneity moderators. Pregnancy-related complications and adverse pregnancy outcomes. Fifty cohort studies comprising 161,370 ART and 2,280,241 spontaneously conceived singleton pregnancies were identified. The ART singleton pregnancies had a significantly increased risk of pregnancy-induced hypertension (relative risk [RR] 1.30, 95% confidence interval [CI] 1.04-1.62; I(2) = 79%), gestational diabetes mellitus (RR 1.31, 95% CI 1.13-1.53; I(2) = 6%), placenta previa (RR 3.71, 95% CI 2.67-5.16; I(2) = 72%), placental abruption (RR 1.83, 95% CI 1.49-2.24; I(2) = 22%), antepartum hemorrhage (RR 2.11, 95% CI 1.86-2.38; I(2) = 47%), postpartum hemorrhage (RR 1.29, 95% CI 1.06-1.57; I(2) = 65%), polyhydramnios (RR 1.74, 95% CI 1.24-2.45; I(2) = 0%), oligohydramnios (RR 2.14, 95% CI 1.53-3.01; I(2) = 0%), cesarean sections (RR 1.58, 95% CI 1.48-1.70; I(2) = 92%), preterm birth (RR 1.71, 95% CI 1.59-1.83; I(2)=80%), very preterm birth (RR 2.12, 95% CI 1.73-2.59; I(2) = 90%), low birth weight (RR 1.61, 95% CI 1.49-1.75; I(2) = 80%), very low birth weight (RR 2.12, 95% CI 1.84-2.43; I(2) = 67%), small for gestational age (RR 1.35, 95% CI 1.20-1.52; I(2) = 82%), perinatal mortality (RR 1.64, 95% CI 1.41-1.90; I(2)=45%), and congenital malformation (RR 1.37, 95% CI 1.29-1.45; I(2)=41%).

    To compare first trimester 2D conventional and 3D power Doppler angiography measures in twins and singletons following assisted reproduction. We prospectively evaluated 50 singleton and 47 twin pregnancies that eventually ended in live births. Patients were recruited from a single assisted reproductive technology (ART) center with standard treatment protocols. Obstetric ultrasound was performed at 8-9 weeks +6 days. Intervillous flow, uteroplacental circulation and uterine artery pulsatility (PI) and resistance index (RI) using two-dimensional (2D) ultrasound examination were evaluated. Using three-dimensional (3D) power Doppler angiography, placental volume and the 3D power Doppler indices from the intervillous and uteroplacental circulation were calculated. Demographic and cycle characteristics were similar in mothers of singletons and twins. Placental volume was significantly (1.6-fold) larger in twins. Vascular density and blood perfusion in the intervillous space were lower in twins. The comparison of the other parameters did not show significant differences between singletons and twins. The data confirm the larger placental volume in twins, denoting a probable higher production of placental hormones that would support an early twin pregnancy. The lower vascular density and blood perfusion in the intervillous space in twins may also confer a reproductive advantage to them.

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

    To answer the questions: Are perinatal reproductive hormone profiles different in case of a twin compared with a singleton pregnancy? Are reproductive endocrine profiles of twin girls influenced by their male co-twin and vice versa? Prospective cohort study from January 2004 to October 2009. Not applicable. A total of 204 mothers of twins and 248 singleton control subjects, aged >18 years, pregnant with a twin or singleton and no endocrine disease or malignancy. Blood samples were collected at mid-gestation from the mother and at delivery from the mothers and the umbilical cords. Estrogens, androgens, sex hormone-binding globulin, progesterone, and gonadotropins were measured. Hormonal profiles were compared between singletons and twins, different types of twins, and opposite-sex and same-sex twins. Estrogen and progesterone concentrations were higher in mothers of twins compared with singletons, but twin babies had lower estrogen and progesterone concentrations at birth. Opposite-sex twin girls did not have higher androgens in cord blood compared with same-sex twin girls. Boys of an opposite-sex twin had lower luteinizing hormone concentrations compared with dizygotic twin boys with a brother as a co-twin. Children from a twin are not overexposed to sex steroids at the time of birth, despite higher concentrations in their mothers, and girls from opposite sex twins do not show androgenic influences from their male co-twin. The female co-twin may influence the hypothalamic-pituitary-testicular axis of her brother via central inhibition. Copyright © 2015 American Society for Reproductive Medicine.

  1. Velamentous Cord Insertion in a Singleton Pregnancy: An Obscure Cause of Emergency Cesarean—A Case Report

    Directory of Open Access Journals (Sweden)

    Juliana Rocha

    2012-01-01

    Full Text Available Approximately 2% of low-risk pregnant women still require an emergency Cesarean section after the onset of labor. Because it is likely that half of these cases are associated with placental and umbilical cord abnormalities, it is thought that prenatal detection of such abnormalities would reduce the number of emergency cesarean sections in low-risk women. Velamentous cord insertion is an abnormal cord insertion in which the umbilical vessels diverge as they traverse between the amnion and chorion before reaching the placenta. With a reported incidence of 1% in singleton pregnancies, it has been associated with several obstetric complications. This condition has been diagnosed by ultrasonography with a sensitivity of 67% and specificity of 100% in the second trimester. The present case highlights the importance of the systematic assessment of the placental cord insertion site at routine obstetric ultrasound and the potential of identifying pregnancies with velamentous insertion and, therefore, those at risk for obstetric complications.

    The aim of our study was to assess associations between smoking behavior before and during pregnancy and selected adverse birth outcomes. This study is based on the Murmansk County Birth Registry (MCBR). Our study includes women who delivered a singleton pregnancy after 37 weeks of gestation (N = 44,486). Smoking information was self-reported and assessed at the first antenatal visit during pregnancy. We adjusted for potential confounders using logistic regression. The highest proportion of infants with low values of birth weight, birth length, head circumference, ponderal index and of the Apgar score at 5 min was observed for women who smoked both before and during pregnancy. We observed a dose-response relationship between the number of cigarettes smoked per day during pregnancy and the odds of the aforementioned adverse birth outcomes; neither were there significant differences in their occurrences among non-smokers and those who smoked before but not during pregnancy. Moreover, smoking reduction during pregnancy relative to its pre-gestation level did not influence the odds of the adverse birth outcomes. Our findings emphasize a continued need for action against tobacco smoking during pregnancy.

    To compare and confirm the impact of prepregnancy body mass index on pregnancy outcome in women with a singleton conceived by assisted reproductive technology and spontaneously conceived pregnancy. A sample of 165 and 247 pregnant women with and without assisted reproductive technology were retrospectively recruited from electronic medical charts of C hospital. There were significant differences between the two groups for maternal age, paternal age, length of marriage, prepregnancy body mass index, parity, spontaneous abortion experience, and preterm delivery. A prepregnancy body mass index of ≥25 was associated with higher risk for maternal and neonatal complication in the assisted reproductive technology group. The results indicate that a higher prepregnancy body mass index is associated with increased risks for adverse pregnancy outcomes for women using assisted reproductive technology. So these women need appropriate care to compensate for the risk.

    To study the effects on the fetus of variations in maternal glucose tolerance, a 25 g rapid intravenous glucose tolerance test was performed at or about 32 weeks gestation in 917 randomly selected nondiabetic women with singleton pregnancies. The results were withheld from the patients and their obstetricians and paediatricians, and no treatment or advice was offered. Fasting plasma glucose and indices of glucose disposal (including a new index which we have termed "summed glucose") were distributed unimodally, with no evidence of a separate pathological group towards the diabetic end of the distributions. Significant associations were found between maternal glucose metabolism and various measures of neonatal nutrition and morbidity, including the incidence of congenital malformations and morbidity related to asphyxia, suggesting that variations within the normal range in maternal glucose metabolism can influence growth and development in the fetus. These relationships were continuous throughout the range of maternal glucose tolerance and were not of predictive value in individual cases.

    Full Text Available Abstract Background 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. Methods/Design 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. Discussion 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.

    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

    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 39(th) 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. Copyright © 2015. Published by Elsevier Taiwan.

    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.

    The purpose of this paper was to examine the obstetric and neonatal outcomes of preterm singleton pregnancies complicated by placental abruption following preterm premature rupture of membranes (p-PROM) compared with those without p-PROM. We reviewed the obstetric records of 95 singleton deliveries complicated by placental abruption at 22–36 weeks' gestation. The incidence of placental abruption in singleton pregnancies with p-PROM was 4.7%, and the crude odds ratio of placental abruption for women following p-PROM was 6.50 (P < 0.01). Of the 95 cases of placental abruption in preterm singleton deliveries, 64 cases (67.4%) occurred without p-PROM and 31 cases (32.6%) occurred following p-PROM. The incidence of histological chorioamnionitis stage III in the patients following p-PROM was significantly higher than that in the patients without p-PROM (P = 0.02). The rate of emergency Cesarean deliveries associated with nonreassuring fetal status (NRFS) in the patients following p-PROM was significantly lower than that in the patients without p-PROM. However, there were no significant differences in the maternal and neonatal outcomes between the patients with and without p-PROM. Although p-PROM may be one of important risk factors for placental abruption associated with chorioamnionitis, it may not influence the perinatal outcomes in preterm placental abruption.

Academic infertility clinic. One hundred sixty patients acupuncture 25 minutes before and after ET. Subjects completed a McGill Pain Questionnaire regarding their clinical symptoms during ET. Clinical PR and clinical symptoms during ET. While the overall clinical PR was 51.25%, there was no significant difference between the arms of the study (true = 45.3% vs. sham = 52.7%); 33.1% of the patients had ultrasound-documented singleton pregnancy, and 15% of patients had twin gestations, while one patient in the true arm had a triplet gestation. There were significant differences in the subjective, affective, and total pain experience between both arms. The subjects in the true arm described their acupuncture session as being more "tiring" and "fearful" and experienced more "achiness" compared with their sham counterparts. There was no statistically significant difference in the clinical or chemical PRs between both groups. Patients undergoing true acupuncture had differing sensory experiences compared with patients in the sham arm. There were no significant adverse effects observed during the study, suggesting that acupuncture is safe for women undergoing ET. Copyright © 2011 American Society for Reproductive Medicine.

    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.

    Maternal overweight and obesity are associated with increased risks of birth-asphyxia-related outcomes, but the mechanisms are unclear. If a change of exposure (i.e., maternal body mass index [BMI]) over time influences risks, this would be consistent with a causal relationship between maternal BMI and offspring risks. Our objective was to investigate associations between changes in maternal BMI between consecutive pregnancies and risks of birth-asphyxia-related outcomes in the second offspring born at term. This study was a prospective population-based cohort study that included 526,435 second-born term (≥37 wk) infants of mothers with two consecutive live singleton term births in Sweden between January 1992 and December 2012. We estimated associations between the difference in maternal BMI between the first and second pregnancy and risks of low Apgar score (0-6) at 5 min, neonatal seizures, and meconium aspiration in the second-born offspring. Odds ratios (ORs) were adjusted for BMI at first pregnancy, maternal height, maternal age at second delivery, smoking, education, mother´s country of birth, inter-pregnancy interval, and year of second delivery. Analyses were also stratified by BMI (neonatal seizures, and meconium aspiration increased with inter-pregnancy weight gain. Compared with offspring of mothers with stable weight (BMI change of -1 to neonatal seizures and meconium aspiration were 1.42 (95% CI 1.00-2.02) and 1.78 (95% CI 1.19-2.68), respectively. The increased risk of neonatal seizures related to weight gain appeared to be restricted to mothers with BMI neonatal resuscitation efforts. Risks of birth-asphyxia-related outcomes increased with maternal weight gain between pregnancies. Preventing weight gain before and in between pregnancies may improve neonatal health.

    Fetal fibronectin is an extracellular matrix glycoprotein that is produced by amniocytes and cytotrophoblasts and has been shown to predict spontaneous preterm birth. The aim of this systematic review and metaanalysis of randomized clinical trials was to evaluate the effect of the use of fetal fibronectin in the prevention of preterm birth in singleton pregnancies with threatened preterm labor. The research was conducted with the use of MEDLINE, EMBASE, Web of Sciences, Scopus, ClinicalTrial.gov, OVID, and Cochrane Library as electronic databases from the inception of each database to February 2016. Selection criteria included randomized clinical trials of singleton gestations with threatened preterm labor that were assigned randomly to management based on fetal fibronectin results (ie, intervention group) or not (ie, comparison group). Types of participants included women with singleton gestations at 23 0/7 to 34 6/7 weeks with threatened preterm labor. Studies that included management that was also based on the use of sonographic cervical length were excluded. The primary outcome was preterm birth at birth at control group. No differences were found in the number of women who delivered within 7 days (12.8% vs 14.5%; relative risk, 0.76; 95% confidence interval, 0.47-1.21), in the mean of gestational age at delivery (mean difference, 0.20 week; 95% confidence interval, -0.26 to 0.67), in the rate of maternal hospitalization (27.4% vs 26.9%; relative risk, 1.07; 95% confidence interval, 0.80-1.44), in the use of tocolysis (25.3% vs 28.2%; relative risk, 0.97; 95% confidence interval, 0.75-1.24), antenatal steroids (29.2% vs 29.2%; relative risk, 1.05; 95% confidence interval, 0.79-1.39), in the mean time in the triage unit (mean difference, 0.60 hour; 95% confidence interval, -0.03 to 1.23) and in neonatal outcomes that included respiratory distress syndrome (1.3% vs 1.5%; relative risk, 0.91; 95% confidence interval, 0.06-14.06), and admission to the neonatal

    Spontaneous preterm birth is a major cause of perinatal morbidity and mortality. It is unclear if a cervical pessary can reduce the risk of spontaneous preterm delivery. To test whether in asymptomatic women with singleton pregnancies and no prior spontaneous preterm birth but with short cervical length on transvaginal ultrasound, use of a cervical pessary would reduce the rate of spontaneous preterm birth at less than 34 weeks of gestation. Parallel-group, nonblinded, randomized clinical trial conducted from March 1, 2016, to May 25, 2017, at a single center in Italy. Asymptomatic women with singleton gestations, no previous spontaneous preterm births, and cervical lengths of 25 mm or less at 18 weeks 0 days to 23 weeks 6 days of gestation were eligible. Patients were randomized 1:1 to receive either cervical pessary (n = 150) or no pessary (n = 150). The pessary was removed between 37 weeks 0 days and 37 weeks 6 days of gestation or earlier if clinically indicated. The control group received standard care. For cervical length of 20 mm or shorter, women in both groups were prescribed vaginal progesterone, 200 mg/d, until 36 weeks 6 days of gestation. No bed rest or activity restriction was recommended. The primary end point was spontaneous preterm birth at less than 34 weeks of gestation. Secondary outcomes were adverse events. Among 300 women who were randomized (mean age, 29 [SD, 6.3] years; mean gestational age, 22 [SD, 1.3] weeks), 100% completed the trial. The primary end point occurred in 11 women (7.3%) in the pessary group and 23 women (15.3%) in the control group (between-group difference, -8.0% [95% CI, -15.7% to -0.4]; relative risk, 0.48 [95% CI, 0.24-0.95]). During follow-up, the pessary group had a higher rate of increased or new vaginal discharge (86.7% vs 46.0%; between-group difference, +40.7% [95% CI, +30.1%-+50.3%]; relative risk, 1.88 [95% CI, 1.57-2.27]).

    Full Text Available Abstract Background Women with a short cervical length in mid-trimester pregnancy have a higher risk of preterm birth and therefore a higher rate of neonatal mortality and morbidity. Progesterone can potentially decrease the number of preterm births and lower neonatal mortality and morbidity. Previous studies showed good results of progesterone in women with either a history of preterm birth or a short cervix. However, it is unknown whether screening for a short cervix and subsequent treatment in mid trimester pregnancy is effective in low risk women. Methods/Design We plan a combined screen and treat study among women with a singleton pregnancy without a previous preterm birth. In these women, we will measure cervical length at the standard anomaly scan performed between 18 and 22 weeks. Women with cervical length ≤ 30 mm at two independent measurements will be randomly allocated to receive either vaginal progesterone tablets or placebo between 22 and 34 weeks. The primary outcome of this trial is adverse neonatal condition, defined as a composite outcome of neonatal mortality and severe morbidity. Secondary outcomes are time to delivery, preterm birth rate before 32, 34 and 37 weeks, days of admission in neonatal intensive care unit, maternal morbidity, maternal admission days for preterm labour and costs. We will assess growth, physical condition and neurodevelopmental outcome of the children at two years of age. Discussion This study will provide evidence for the usefulness and cost-effectiveness of screening for short cervical length at the 18-22 weeks and subsequent progesterone treatment among low risk women.

    To evaluate clinical outcomes of women with singleton pregnancies that underwent intra-amniotic dye instillation (amniodye test) following equivocal diagnosis of prelabor rupture of membranes (PROM). Records of 34 pregnant women who underwent amniodye test for equivocal PROM were reviewed. Comparisons of characteristics, amniotic fluid (AF) cultures, AF interleukin (IL)-6 concentrations, and placenta pathology results between women who tested positive and those who tested negative were performed. A sub-analysis of women who were amniodye test-negative was also performed. (1) Commonest indication for amniodye test was a typical history of PROM with positive conventional tests and persistently normal AF volume, (2) amniodye test-positive women had a shorter procedure-to-delivery interval (p = 0.008), and a greater proportion of histologic acute chorioamnionitis (p = 0.04) and funisitis (p = 0.01) than amniodye-negative women, and (3) in addition to similarities to women with amniodye-positive test, amniodye test-negative women who delivered <34 weeks, had a greater proportion of women with risk for preterm birth (p = 0.04), than their counterparts who delivered between 34 0/7 and 36 6/7 weeks. Equivocal diagnosis of PPROM should warrant an amniodye test to avoid iatrogenic intervention in women with intact amniotic membranes. AF analysis should be performed in amniodye test-negative women.

    To explore obstetric and perinatal outcomes in singleton pregnancies occurring as a result of fresh and thawed frozen embryo transfer using anonymized Human Fertilisation and Embryology Authority data. Retrospective cohort study. Not applicable. Singleton births after IVF/intracytoplasmic sperm injection cycles in the United Kingdom (1991-2011). A total of 112,432 cycles (95,911 fresh and 16,521 frozen) were analyzed using multivariate logistic regression to explore associations between type of embryo transferred (frozen vs. fresh) and obstetric and perinatal outcomes. Relative risks (RRs) and their 99.5% confidence intervals (CIs) were calculated using Stata 14 MP, adjusting for potential confounders. Birth weight. The adjusted RR (99.5% CI) of low birth weight [0.73 (0.66-0.80)] and very low birth weight [0.78 (0.63-0.96)] were all lower after frozen embryo transfer; however, RR of having a high birth weight baby was higher [1.64 (1.53-1.76)]. There was no difference in RR of preterm birth [0.96 (0.88-1.03)], very preterm birth [0.86 (0.70-1.05)], and congenital anomalies [0.86 (0.73-1.01)]. The findings of low birth and very low birth weight after thawed frozen embryo transfer are consistent with the literature and provide reassurance regarding the outcome of pregnancies after frozen embryo transfers. However, they highlight the possibility of high birth weight in these babies. Because these results are based on observational data, further evidence from randomized, controlled trials is needed before elective cryopreservation of all embryos is practiced in preference to the current practice of transfer of fresh embryos.

    Twin pregnancies are at increased risk for perinatal morbidity and death because of many factors that include a high incidence of preterm delivery. Compared with singleton pregnancies, overall perinatal risk of death is higher in twin pregnancies; however, for the preterm period, the perinatal mortality rate has been reported to be lower in twins. The purpose of this study was to compare perinatal mortality rates in relation to gestational age at birth between singleton and twin pregnancies, taking into account socioeconomic status, fetal sex, and parity. We studied perinatal mortality rates according to gestational age at birth in 1,502,120 singletons pregnancies and 51,658 twin pregnancies without congenital malformations who were delivered between 2002 and 2010 after 28 weeks of gestation. Data were collected from the nationwide Netherlands Perinatal Registry. Overall the perinatal mortality rate in twin pregnancies (6.6/1000 infants) was higher than in singleton pregnancies (4.1/1000 infants). However, in the preterm period, the perinatal mortality rate in twin pregnancies was substantially lower than in singleton pregnancies (10.4 per 1000 infants as compared with 34.5 per 1000 infants, respectively) for infants who were born at <37 weeks of gestation; this held especially for antepartum deaths. After 39 weeks of gestation, the perinatal mortality rate was higher in twin pregnancies. Differences in parity, fetal sex, and socioeconomic status did not explain the observed differences in outcome. Overall the perinatal mortality rate was higher in twin pregnancies than in singleton pregnancies, which is most likely caused by the high preterm birth rate in twins and not by a higher mortality rate for gestation, apart from term pregnancies. During the preterm period, the antepartum mortality rate was much lower in twin pregnancies than in singleton pregnancies. We suggest that this might be partially due to a closer monitoring of twin pregnancies, which indirectly

    Full Text Available The impact of obesity on the outcome of assisted reproduction treatments is debatable. Several studies show that obese women have worse outcomes after undergoing fertility treatment. The researches show a worse response to ovulation induction. In the ovarian stimulation stage these women produce fewer follicles. Fertilization rates are poorer and the embryo quality is lower in young women suffering from obesity. According to some studies, pregnancy rates are lower in obese women and there is an increased risk of early pregnancy loss. Weight loss increases the chance of spontaneous ovulation and conception in women that suffer from overweight and obesity.The aim of this study is to describe the different influencing factors related to body mass index in pregnancy rate achieved by artificial insemination in our population.The results of this study show significant results in patients with higher body mass index was positively associated with duration of infertility, lower levels of luteinizing hormone and intrauterine artificial insemination indication increased .It appears more frequently, but without significant result, anovulation and unexplained cause of infertility among obese women, longer cycles, fewer antral follicles and get fewer mature follicles. The average of pregnancy rates was 12.6% but it did not differ significantly among the body mass index categories.

    This study investigated the occurrence of peritoneal fluid in women undergoing intrauterine insemination (IUI) and its correlation with the stage of pelvic endometriosis and its influence on pregnancy outcomes. A retrospective case-control design was used to recruit 272 infertile women with pelvic endometriosis. The treatment protocol consisted of controlled ovarian hyperstimulation with downregulation and gonadotropin for IUI treatment following ultrasound and laparoscopic intervention. The amount and color of the peritoneal fluid were determined during laparoscopy. The mean amount of peritoneal fluid with pelvic endometriosis that was detected using transvaginal ultrasound was ~ 15.1 mL. Women whose cycles contained more peritoneal fluid had significantly lower pregnancy rates (17.2% and 31.3%, respectively). The total clinical pregnancy rate was not significantly different between the two groups with reddish and yellowish peritoneal fluid who had pelvic endometriosis. Pelvic endometriosis and peritoneal fluid, detected through vaginal ultrasound, have negative effects on the pregnancy outcome of IUI treatment. Copyright © 2013. Published by Elsevier B.V.

    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).

    The objective of this study was to explore women's expectations and experiences of undergoing second trimester abortion. This is a cross-sectional study using a screening questionnaire and semi-structured interviews for data collection. Thirty-one women filled out the questionnaire and 23 of them were later interviewed. The questionnaires were analyzed by descriptive statistics. The interviews were recorded, transcribed verbatim and analyzed with qualitative content analysis. Indications for the abortion were fetal malformation or unintended pregnancy. The women expressed similar feelings and these were irrespective for the reason for having an abortion. Both physical and mental pain was experienced during the abortion process and described by the women. Taking the mifepristone-pill was experienced as especially emotionally difficult for many participants. Professional support from the staff together with support from the partner, a friend or relative helped in transforming the worries related to something unknown to feelings of coping with a new and hard experience. Prior to the abortion most women stated that they did not want to view the fetus but women who chose to view the fetus described this as a way of confronting the reality and an opportunity to say farewell to the pregnancy/fetus. The analysis of the interview transcripts revealed five themes mirroring the women's experiences, thoughts and feelings related to the abortion. The decision to undergo second trimester abortion sometimes exposes women to strong and conflicting emotions which are irrespective for the reason for having an abortion. Despite this women do not regret their decision to terminate the pregnancy. This analysis shows that their rational thinking outweighs their emotionally difficult feelings. It is important for the attending staff to be responsive to the needs of each individual woman whatever the indication is for the abortion.

    The objective of this study was to assess the frequency of urinary tract infection (UTI) with urine samples obtained via catheterization among women undergoing cesarean delivery at term pregnancy. A cross-sectional study involving 159 women in whom cesarean delivery was conducted at term pregnancy after a regular follow-up from first to third trimester. For screening and diagnosis of UTI during antenatal period, the authors used dipstick test and microscopic urinalysis, and urine culture was used in the presence of symptomatic UTI unresponsive to initial antibiotic therapy. A urine sample was obtained immediately after insertion of Foley catheter for urine dipstick test, microscopic urinalysis, and culture during cesarean delivery. Obstetric and UTI data were recorded. Of 159 pregnant women, 95 (59.8%) did not develop UTI during antenatal care. There was no patient with symptomatic UTI at the admission for cesarean delivery. The authors found UTI with urine dipstick and microscopic urinalysis in 12 patients and of them, four patients had no history of UTI, and all the remaining eight patients had asymptomatic UTI during antenatal follow-up. UTI according to urine culture was encountered in three patients, two of them had one episode of UTI, and one had two episodes of UTI during antenatal follow-up. After regular antenatal follow-up screening with urine dipstick, microscopic urinalysis, and counseling of pregnant women regarding UTIs, the frequency of bacteriuria decreases considerably during cesarean delivery.

    Full Text Available Objective. To evaluate the ethics of performing research in the field of maternal-fetal medicine involving women undergoing pregnancy termination. Methods. We identified published pharmacological studies performed during elective pregnancy termination. In addition, a questionnaire was administered to investigate whether this research would be acceptable to professionals performing research in the field of maternal-fetal pharmacology. Results. The majority of participants believe that this form of research is necessary to furthering our understanding of drug use in pregnancy. Twenty studies were identified in women undergoing a pregnancy termination where exogenous drug was administered and drug measurement conducted during an abortion. The majority of studies were completed by international groups and not in North America or Western Europe. Conclusions. While a majority of respondents to the survey felt that, although research in women undergoing a pregnancy termination is ethically acceptable, 40% stated that it is not likely to be approved by institutional review boards of most North American medical institutions.

    In-vitro fertilization is a known risk factor for ectopic pregnancies. We sought to establish the risk factors for ectopic pregnancy in GnRH antagonist cycles examining patient and stimulation parameters with an emphasis on ovulation trigger. We conducted a retrospective, cohort study of 343 patients undergoing 380 assisted reproductive technology (ART) cycles with the GnRH antagonist protocol and achieving a clinical pregnancy from November 2010 through December 2015. Significant risk factors for ectopic pregnancy in the univariate analysis included prior Cesarean section (CS), endometriosis, mechanical factor infertility, longer stimulation, elevated estradiol and progesterone levels, GnRH agonist trigger, higher number of oocytes aspirated, and insemination technique. Independent risk factors for ectopic pregnancy in the multivariate analysis included GnRH agonist trigger, higher number of oocytes aspirated, insemination technique, and prior Cesarean section. Excessive ovarian response, IVF (as opposed to ICSI), prior Cesarean section and GnRH agonist trigger were found to be independent risk factors for ectopic pregnancy. Caution should be exercised before incorporating the GnRH agonist trigger for indications other than preventing OHSS. When excessive ovarian response leads to utilization of GnRH agonist trigger, strategies for preventing ectopic pregnancy, such as a freeze all policy or blastocyst transfer, should be considered. Further studies should elucidate whether adjusting the luteal support can reduce the ectopic pregnancy risk.

    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.

    Full Text Available Abstract Background Chlamydia trachomatis infection (CTI is the most frequent sexual transmitted disease (STI in Switzerland but its prevalence in undocumented migrants is unknown. We aimed to compare CTI prevalence among undocumented migrants undergoing termination of pregnancy (ToP to the prevalence among women with residency permit. Methods This prospective cohort study included all pregnant, undocumented women presenting from March 2005 to October 2006 to the University hospital for ToP. The control group consisted of a systematic sample of pregnant women with legal residency permit coming to the same hospital during the same time period for ToP Results One hundred seventy five undocumented women and 208 women with residency permit (controls were included in the study. Mean ages were 28.0 y (SD 5.5 and 28.2 y (SD 7.5, respectively (p = 0.77. Undocumented women came primarily from Latin-America (78%. Frequently, they lacked contraception (23%, controls 15%, OR 1.8, 95% CI 1.04;2.9. Thirteen percent of undocumented migrants were found to have CTI (compared to 4.4% of controls; OR 3.2, 95% CI 1.4;7.3. Conclusion This population of undocumented, pregnant migrants consisted primarily of young, Latino-American women. Compared to control women, undocumented migrants showed higher prevalence rates of genital CTI, which indicates that health professionals should consider systematic screening for STI in this population. There is a need to design programs providing better access to treatment and education and to increase migrants' awareness of the importance of contraception and transmission of STI.

    Objective: To discuss the nursing care for patients with placenta previa,who receive uterine arterial catheterization and embolization in the second trimester of pregnancy. Methods: By using superselective catheterization with Seldinger technique, bilateral uterine artery angiography and embolization were performed in 16 patients with placenta previa in the second trimester of pregnancy. Two to four hours after the procedure, rivanol intra-amniotic injection was employed to induce the abortion. Close perioperative observation and careful nursing were carried out. Results: The fetus with its subsidiary tissue was delivered in a mean time of 4.5 hours after the operation in 15 cases. No postpartum hemorrhage occurred. Induced abortion failed in one case with 26 weeks pregnancy because of a scar uterus and cervical dystocia. Hysterotomy was performed 6 days later, blood loss during the operation was about 100 ml. No nursing care related complications occurred in all 16 patients. Conclusion: Uterine arterial embolization is very helpful in making the induced abortion for the treatment of bleeding placenta previa in the second trimester of pregnancy. Strengthening of perioperative care can improve successful rate of interventional therapy and prevent the occurrence of complication. (authors)

    Laparoscopic surgery is well accepted as a safe technique when performed on a third trimester pregnant woman. The aim is to describe the anaesthetic management of a group of patients undergoing this type of surgery. An analysis was made of records of 6 patients in their third trimester of pregnancy and who underwent urgent laparoscopic surgery from 2011 to 2013. The study included 6 patients, with a diagnosis of acute cholecystitis in 4 of them. The other 2 patients had acute appendicitis, both of who presented threatened preterm labour. The most frequent indications for laparoscopic surgery during the last trimester of birth were found to be acute cholecystitis and acute appendicitis.

    This study is part of a longitudinal cohort undertaken in both women and men to describe live birth outcome after undergoing assisted reproductive technology (ART) treatment in a clinical setting. Another objective was to follow women and men living with children from other alternatives after ART, such as adoption. A total of 439 (80.5%) women and 423 (77.6%) men were included in the baseline cohort (2005-2007). Live birth rate after ART was 24.8% at baseline. Up to 5 years later (2010-2011) the same participants were sent individual postal questionnaires (n = 439). Overall, 278 (63.3%) women and 183 (41.7%) men filled in and returned the questionnaire at follow up. The majority of women (91.7%) and men (93.4%) were living with children. A total of 225 (80.9%) women had a live birth at follow up. Of these, almost three of four (71.6%) had a live birth after ART and more than one of four (28.0%) after spontaneous pregnancies or both. Of these, 52 (26.1%) women had a subsequent live birth after successful ART and 26 (32.9%) women after unsuccessful ART. Nineteen (6.8%) women and 13 (7.1%) men had a child after adoption. Almost one of five (19.1%) women had no live birth at follow up. The majority of women and men were living with children, resulting from a live birth after ART, spontaneous pregnancy and/or adoption up to 5 years later. However, almost one of five had no live birth at follow up. © 2017 The Authors.

    To review and compare pregnancy outcomes of patients undergoing history-indicated, ultrasound-indicated, or rescue cerclage. Case series with internal comparison. A regional obstetric unit in Hong Kong. Women undergoing cervical cerclage at Kwong Wah Hospital between 1 January 2001 and 31 December 2011. Cervical cerclage. Pregnancy outcomes including miscarriage, gestational age at delivery, birth weight, and duration of pregnancy prolongation. Overall, 47 patients were included. Nine (19.1%) pregnancies resulted in miscarriage. The median gestational age at delivery was 35.7 weeks. Among the 23 patients who had history-indicated cerclage, only four (17.4%) had three or more previous second-trimester miscarriages or preterm deliveries. Among the 15 patients who had ultrasound-indicated cerclage, preoperative cervical length of ≤1.5 cm was associated with shorter prolongation of pregnancy, compared with that of >1.5 cm (median, 12.1 vs 18.4 weeks; P=0.009). Among the nine women who had rescue cerclage, those who underwent the procedure before 20 weeks of gestation delivered earlier than those underwent cerclage later (median, 22.5 vs 34.1 weeks; P=0.048). Patients eligible for the Royal College of Obstetricians and Gynaecologists-recommended history-indicated cerclage remain few. The majority of patients may benefit from serial ultrasound monitoring of cervical length with or without ultrasound-indicated cerclage.

    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.

    The purpose of this study was to examine the effects of psychosocial interventions on the mental health, pregnancy rates, and marital function of infertile couples undergoing in vitro fertilization (IVF), as determined through RCT studies. Using the electronic databases PubMed, EMBase, Cochrane Library, CINAHL, PsycInfo, and CAJ, a systematic literature search was conducted in July 2015. MeSH terms, key words, and free words such as "infertility," "fertilization in vitro," "psychotherapy," "intervention," "anxiety," "depression," and "marital satisfaction" were used to identify all potential studies. The quality of the studies that were included was assessed using the risk of bias assessment tool developed by the Cochrane Back Review Group. Descriptive analysis was adopted to synthesize the results. A total of 20 randomized controlled trials were included in this review. There were reports of positive effects on the anxiety levels, pregnancy rates, or marital function of infertile couples in six studies that adopted different psychosocial approaches, including mind body intervention (Eastern body-mind-spirit, Integrative body-mind-spirit, and Mind/body intervention), cognitive behavioral therapy, group psychotherapy, and harp therapy. However, there were methodological or practical issues related to measurement points and attrition rates in these studies. None of these interventions were found to be efficacious in relieving the depression or stress of individuals or couples undergoing IVF treatment. None of the included studies tackled or measured the mental health status of the couples during the most stressful time of waiting for the pregnancy results of their treatment. A complex intervention, based on sound evidence, should be developed targeting both females and males of infertile couples undergoing IVF treatment, particularly during the stressful period of waiting for the results of the pregnancy test result and after failed cycles.

    To evaluate how varicocele repair (VR) impacts pregnancy (PRs) and live birth rates in infertile couples undergoing assisted reproduction wherein the male partner has oligospermia or azoospermia and a history of varicocele. Systematic review and meta-analysis. Not applicable. Azoospermic and oligospermic males with varicoceles and in couples undergoing assisted reproductive technology (ART) with IUI, IVF, or testicular sperm extraction (TESE) with IVF and intracytoplasmic sperm injection (ICSI). Measurement of PRs, live birth, and sperm extraction rates. Odds ratios for the impact of VR on PRs, live birth, and sperm extraction rates for couples undergoing ART. Seven articles involving a total of 1,241 patients were included. Meta-analysis showed that VR improved live birth rates for the oligospermic (odds ratio [OR] = 1.699) and combined oligospermic/azoospermic groups (OR = 1.761). Pregnancy rates were higher in the azoospermic group (OR = 2.336) and combined oligospermic/azoospermic groups (OR = 1.760). Live birth rates were higher for patients undergoing IUI after VR (OR = 8.360). Sperm retrieval rates were higher in persistently azoospermic men after VR (OR = 2.509). Oligospermic and azoospermic patients with clinical varicocele who undergo VR experience improved live birth rates and PRs with IVF or IVF/ICSI. For persistently azoospermic men after VR requiring TESE for IVF/ICSI, VR improves sperm retrieval rates. Therefore, VR should be considered to have substantial benefits for couples with a clinical varicocele even if oligospermia or azoospermia persists after repair and ART is required.

    Poor ovarian response (POR) often means low success rates after in vitro fertilisation (IVF). We aim to study the impact of a low-dose growth hormone (GH) supplementation in pregnancy rates in poor responders in a prospective, self-controlled study of 64 poor responders to previous IVF cycles, who failed to achieve pregnancy and were supplemented with low-doses of GH in a subsequent cycle using the same gonadotropin dose and protocol. Our primary endpoint was the clinical pregnancy rate (CPR), considering secondary endpoints, the number of retrieved oocytes, embryos, embryo quality and the proportion of cycles with embryo transfer. CPR in the GH group was 34.4%. Significant differences were observed for the GH group both in the number of top quality embryos (0.64 ± 0.88 versus 1.03 ± 1.17, p < 0.05) and cryopreserved embryos (0.3 ± 0.81 versus 0.85 ± 1.49, p < 0.05). This is, to our knowledge, the first clinical trial to use a low dose of GH as a supplement for IVF in POR patients. Despite this low dose, we achieved excellent success rates in patients with a very poor prognosis, at a reasonable cost and without side effects, which makes this a safe and cost-effective alternative.

    Use of organophosphate flame retardants (PFRs) has increased over the past decade following the phase out of some brominated flame retardants, leading to increased human exposure. We recently reported that increasing maternal PFR exposure is associated with poorer pregnancy outcomes among women from a fertility clinic. Because a small epidemiologic study previously reported an inverse association between male PFR exposures and sperm motility, we sought to examine associations of paternal urinary concentrations of PFR metabolites and their partner's pregnancy outcomes. This analysis included 201 couples enrolled in the Environment and Reproductive Health (EARTH) prospective cohort study (2005-2015) who provided one or two urine samples per IVF cycle. In both the male and female partner, we measured five urinary PFR metabolites [bis(1,3-dichloro-2-propyl) phosphate (BDCIPP), diphenyl phosphate (DPHP), isopropylphenyl phenyl phosphate (ip-PPP), tert-butylphenyl phenyl phosphate (tb-PPP) and bis(1-chloro-2-propyl) phosphate (BCIPP)] using negative electrospray ionization liquid chromatography tandem mass spectrometry (LC-MS/MS). The sum of the molar concentrations of the urinary PFR metabolites was calculated. We used multivariable generalized linear mixed models to evaluate the association of urinary concentrations of paternal PFR metabolites with IVF outcomes, accounting for multiple in vitro fertilization (IVF) cycles per couple. Models were adjusted for year of IVF treatment cycle, primary infertility diagnosis, and maternal urinary PFR metabolites as well as paternal and maternal age, body mass index, and race/ethnicity. Detection rates were high for paternal urinary concentrations of BDCIPP (84%), DPHP (87%) and ip-PPP (76%) but low for tb-PPP (12%) and zero for BCIPP (0%). We observed a significant 12% decline in the proportion of fertilized oocytes from the first to second quartile of male urinary ΣPFR and a 47% decline in the number of best quality embryos

    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

    To evaluate the potential of maternal serum using a disintegrin and metalloprotease 12 (ADAM12) as a marker for Trisomy 21 in Chinese pregnant women. Serum samples were collected and stored from women having a viable singleton pregnancy undergoing first trimester screening for Trisomy 21 between 2006 and 2007. Serum concentration of ADAM12 was measured using an automated time-solved immuno-fluorometric assay from 608 stored serum samples (601 Euploidy and 7 Trisomy 21). Regression analysis was used to determine the expected median in Euploidy pregnancies after adjusting for pregnancy characteristics. The level of ADAM12 MoM was compared between Trisomy 21 and Euploidy pregnancies. Expected median levels in Chinese were compared to that published for Caucasians and Afro-Caribbeans. In Euploidy pregnancies, the concentration of ADAM12 increased with CRL and decreased with maternal weight. The expected median level of ADAM12 in Chinese was significantly lower than Caucasian and Afro-Caribbeans (F=14.2, ppregnancy-associated plasma protein A MoMs (r=0.46; ppregnancies was not significantly different from that in Euploidy pregnancies (z=0.18; p=0.88). ADAM12 concentrations in Chinese are lower than those of Caucasians and Afro-Carribeans; that ADAM12 MoM levels in Euploidy and Trisomy 21 pregnancies were not statistically different.

    To determine whether frozen-thawed blastocyst transfer pregnancy rates (PR) are lower in African-American compared with white women. Retrospective review of frozen blastocyst cycles. University-based assisted reproductive technology (ART) program. All patients who underwent a frozen blastocyst transfer between 2003 and 2008. None. Live birth rate. One hundred sixty-nine patients underwent transfer of a frozen-thawed blastocyst. African-American women had a higher incidence of leiomyoma (40% vs. 10%) and tubal and uterine factor infertility. There was no difference in the live birth rate for African-American patients (28.0%) compared with white patients (30.2%). Of the patients who underwent a frozen-thawed blastocyst transfer, 58% (n=98) had their fresh, autologous IVF cycle, which produced the cryopreserved blastocyst, at Walter Reed Medical Center. A higher peak serum E2 level was noted in African-American patients (5,355 pg/mL) compared with white patients (4,541 pg/mL). During the fresh cycle, the live birth rates between African-American and white patients were significantly different at 16.7% versus 39.7%, respectively. Live birth rates after frozen blastocyst transfer are not different between African-American and white women despite a fourfold higher incidence of leiomyomas in African-American women.

    To determine whether different treatment approaches of ectopic pregnancy (EP), particularly unilateral salpingectomy and methotrexate, affect its recurrence rate in patients undergoing in vitro fertilization (IVF). A retrospective cohort study (Canadian Task Force classification II-2). An academic medical center. Patients with a history of a previous EP who achieved pregnancy after IVF cycles between January 2004 and August 2015 were included. The recurrence rate of EP was compared between patients who underwent different treatment approaches for a previous EP. IVF. A total of 594 patients were included. Seventeen patients had a recurrence of EP (2.9%). Patients with a history of ≥2 EPs were associated with a significantly higher recurrence rate of EP than those with 1 previous EP (8.5% vs. 1.8%; p = .01; odds ratio [OR] = 2.2; 95% confidence interval [CI], 1.2-4.4). Patients who underwent unilateral salpingectomy (n = 245) had a comparable recurrence rate of EP after IVF with those who received methotrexate (n = 283) (3.6% vs. 2.8%; p = .5; OR = 1.3; 95% CI, 0.4-3.4). This OR remained unchanged after adjusting for patient's age, number of previous EPs, number of transferred embryos, and peak estradiol level during stimulation (adjusted OR = 1.4; 95% CI, 0.5-3.8). None of the patients who underwent bilateral salpingectomy (n = 45) or salpingostomy (n = 21) had a recurrence of EP after IVF. The recurrence rate of EP significantly correlates with the number of previous EPs. Treatment of EP with methotrexate has a comparable recurrence rate of EP after IVF with unilateral salpingectomy. Therefore, the risk of recurrence should not be a reason to favor salpingectomy over methotrexate in this population. Copyright © 2017 AAGL. Published by Elsevier Inc. All rights reserved.

    2016-03-01

    To investigate pregnancy outcome for fetuses with nuchal translucency (NT) ≥3.5 mm but normal karyotype in the Stockholm (Sweden) area. A retrospective population-based cohort study. From 2006 to 2012, fetal NT was measured in 55123 singleton pregnancies. There were 341 pregnancies with NT thickness ≥3.5 mm; 139 had a normal karyotype, 164 had an abnormal karyotype and 38 were removed from the study. Pregnancy outcome was defined as adverse (termination of pregnancy [TOP], miscarriage [MC], intrauterine fetal death [IUFD], or delivery of a child with structural defects or genetic disorders), or favourable (delivery of a child without any structural defects or genetic disorders diagnosed before discharge). Of the 139 high NT pregnancies with normal karyotype, 110 (79.2%) resulted in live births, one (0.7%) IUFD, 23 (16.5%) TOP and five (3.6%) MC. The risk of an adverse pregnancy outcome increased with increasing NT. Structural fetal defects were found in 28 (19.5%) of pregnancies undergoing second trimester ultrasound screening, of which seven resulted in live births and 21 were terminated. The most common structural defect was cardiac defects. Adverse pregnancy outcome increased with increasing NT, even with normal karyotype, however, the prognosis is good if the second trimester ultrasound screening is normal. © The Author(s) 2015.

    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.

  7. Capture by colour: evidence for dimension-specific singleton capture.

    Harris, Anthony M; Becker, Stefanie I; Remington, Roger W

    2015-10-01

    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.

    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...... and second singleton delivery in Denmark from 1978 to 2007 (n=536,419). The exposures and endpoints were preterm delivery, preeclampsia, fetal growth, placental abruption, and stillbirth after 20 weeks of gestation. We used chi and t test to compare differences between incidences on first and second...... 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...

    To evaluate differences in distribution of estimated fetal weight (EFW) and birth weight (BW) of ongoing fetuses and neonates of the same gestational age. Reference curves for EFW (Hadlock BPD-HC-AC-FL formula, N = 1191) and BW (N = 1036) in singleton pregnancies from 24 +0 to 40 +6 gestational weeks were calculated. Multiple pregnancies, fetuses with major or multiple abnormalities or syndromes and iatrogenic preterm deliveries due to preeclampsia or abnormal fetal Doppler were excluded. The standardized residuals for EFW and BW were calculated and compared. EFW and BW can be accurately described by quadratic equations (R 2  = 0.944 and 0.807, respectively). The distribution of standardized residuals for BW using the EFW formula was negative from 28 +0 to 35 +6 weeks. The 50th and 5th centiles of BW were lower than those of EFW throughout prematurity, and they converged at approximately 38 gestational weeks. The 5th centile for BW was 30% lower than the 5th centile for EFW at 27 weeks, 27.5% lower at 30 weeks and 19.4% at 34 weeks. Preterm infants have lower BW distribution compared to the expected EFW of ongoing pregnancies of the same gestational age, supporting the concept of hidden intrauterine morbidity for a proportion of these infants.

    This study determined the effects of cotinine concentrations in follicular fluid (FF) and seminal plasma (SP) on the pregnancy outcome of couples using assisted reproductive techniques (ARTs). This study was conducted as a case-control study. A total of 217 couples were included in the study. Among these couples, there were nonsmokers (66 women and 40 men), passive smokers (106 women and 54 men), and active smokers (45 women and 123 men). Demographic and smoking data were collected by questionnaire at the onset of treatment. FF and SP samples were obtained from the couples on the day of oocyte retrieval. The cotinine concentrations in the FF and SP of nonsmokers were significantly lower than they were in the other groups (P = 0.001). The difference in cotinine concentrations detected in FF between women with positive pregnancy test results and women with negative pregnancy test results was statistically insignificant. It was also determined that the percentage of clinical pregnancy was lower in nonsmoker women than in passive smoker or smoker women (P > 0.05). Although we found there was no significant difference in the pregnancy outcome between nonsmoker and passive smoker or smoker women, smoking cessation should be an integral part of ARTs.

    To compare demographic characteristics and maternal, fetal, neonatal, and pregnancy outcomes of term macrosomic infants of obese and non-obese mothers. A sample of 1996 singleton, term deliveries was drawn from the All Our Babies Cohort, a prospective, community-based pregnancy cohort. Maternal self-reported socio-demographic and anthropometric information was linked to the clinical data on pregnancy and birth events abstracted from electronic health records. Demographic, obstetrical characteristics and maternal, fetal, neonatal, and pregnancy outcomes of macrosomic infants in obese, overweight, and normal weight women were compared. Multinomial regression analysis assessed the risk factors of macrosomia in primiparous and multiparous women stratified by maternal pre-pregnancy BMI, controlling for confounding variables. Macrosomia affected 10% of pregnancies in the study. Mothers whose infants were macrosomic were more likely to be Caucasian, obese, have had previous deliveries, undergo induction of labour and delivery by emergency C-section, particularly for labour abnormalities. Macrosomic infants were more likely to be delivered postdates, have meconium stained liquor and require resuscitation at birth. There were no significant differences in birth and neonatal outcomes of macrosomic pregnancies between obese, overweight and normal weight women. Pre-pregnancy BMI and gestational age at delivery were risk factors for macrosomia in all women. Ethnicity and history of delivery of a macrosomic infant were additional independent risk factors in multiparas. Obesity in pregnancy increases the risk of delivery of a macrosomic infant in both primiparous and multiparous women. The maternal, fetal and neonatal outcomes of macrosomic pregnancies are similar in obese and normal weight women.

    Implantation failure is the most important cause of recurrent in vitro fertilisation (IVF)/intra cytoplasmic sperm injection (ICSI) failure. It has been reported that endometrial injury using a biopsy catheter resulted in a higher pregnancy rate in following cycle of treatment. The local endometrial trauma increases the implantation rate through the release of chemical mediators such as histamine and growth factor. To evaluate the influence of endometrial biopsy on increasing implantation rate in patients with recurrent implantation failures. In a randomised control trial study, 115 women each with at least two implantation failures were randomly assigned to two groups. In the case group, endometrial biopsy was obtained from patients in the luteal phase of previous cycle, and implantation and clinical pregnancy rates were compared with those of patients in the control group. The implantation rate was determined as 10.9% in the biopsy group compared to 3.38% in the controls. The clinical pregnancy rate was significantly higher in the case group than in controls (27.1% and 8.9% respectively). The results suggest that pregnancy outcome increases through IVF or ICSI after endometrial biopsy.

    To evaluate the predictive capacity for pregnancy of the progesterone level on the day of administering human chorionic gonadotropin, in women submitted to assisted reproductive techniques. An observational study with 914 women submitted to assisted reproductive techniques from August 2014 to June 2016. Total pregnancy rate was 34.58%; in that, the pregnancy rate in women 38 years was, respectively, 42.3%, 38.7% and 16.1% (p<0.001). For embryo transfer in the same cycle, and progesterone of 1.3ng/dL, sensitivity was 4.78%, specificity, 84.18%, accuracy, 56.72%, positive likelihood ratio of 0.3019, and negative likelihood ratio of 1.1312, with receiver operating characteristic curve of 0.46 (95%CI: 0.42-0.49). The progesterone level on the day of administering human chorionic gonadotropin of 1.3ng/dL differs from that empirically adopted at the study site (1.7ng/dL), and has a better predictive capacity for pregnancy in the patients studied. However, the low sensitivity of this examination raises questions about its real importance.

    BACKGROUND Recent systematic reviews of adjuvant acupuncture for IVF have pooled heterogeneous trials, without examining variables that might explain the heterogeneity. The aims of our meta-analysis were to quantify the overall pooled effects of adjuvant acupuncture on IVF clinical pregnancy success rates, and evaluate whether study design-, treatment- and population-related factors influence effect estimates. METHODS We included randomized controlled trials that compared needle acupuncture administered within 1 day of embryo transfer, versus sham acupuncture or no adjuvant treatment. Our primary outcome was clinical pregnancy rates. We obtained from all investigators additional methodological details and outcome data not included in their original publications. We analysed sham-controlled and no adjuvant treatment-controlled trials separately, but since there were no large or significant differences between these two subsets, we pooled all trials for subgroup analyses. We prespecified 11 subgroup variables (5 clinical and 6 methodological) to investigate sources of heterogeneity, using single covariate meta-regressions. RESULTS Sixteen trials (4021 participants) were included in the meta-analyses. There was no statistically significant difference between acupuncture and controls when combining all trials [risk ratio (RR) 1.12, 95% confidence interval (CI), 0.96–1.31; I2 = 68%; 16 trials; 4021 participants], or when restricting to sham-controlled (RR 1.02, 0.83–1.26; I2 = 66%; 7 trials; 2044 participants) or no adjuvant treatment-controlled trials (RR 1.22, 0.97–1.52; I2 = 67%; 9 trials; 1977 participants). The type of control used did not significantly explain the statistical heterogeneity (interaction P = 0.27). Baseline pregnancy rate, measured as the observed rate of clinical pregnancy in the control group of each trial, was a statistically significant effect modifier (interaction P acupuncture across all trials (adjusted R2 = 93%; I2 residual = 9

    Animal experiments suggest that ingestion of pesticide mixtures at environmentally relevant concentrations decreases the number of live-born offspring. Whether the same is true in humans is unknown. To examine the association of preconception intake of pesticide residues in fruits and vegetables (FVs) with outcomes of infertility treatment with assisted reproductive technologies (ART). This analysis included 325 women who completed a diet assessment and subsequently underwent 541 ART cycles in the Environment and Reproductive Health (EARTH) prospective cohort study (2007-2016) at a fertility center at a teaching hospital. We categorized FVs as having high or low pesticide residues using a validated method based on surveillance data from the US Department of Agriculture. Cluster-weighted generalized estimating equations were used to analyze associations of high- and low-pesticide residue FV intake with ART outcomes. Adjusted probabilities of clinical pregnancy and live birth per treatment cycle. In the 325 participants (mean [SD] age, 35.1 [4.0] y; body mass index, 24.1 [4.3]), mean (SD) intakes of high- and low-pesticide residue FVs were 1.7 (1.0) and 2.8 (1.6) servings/d, respectively. Greater intake of high-pesticide residue FVs was associated with a lower probability of clinical pregnancy and live birth. Compared with women in the lowest quartile of high-pesticide FV intake (women in the highest quartile (≥2.3 servings/d) had 18% (95% CI, 5%-30%) lower probability of clinical pregnancy and 26% (95% CI, 13%-37%) lower probability of live birth. Intake of low-pesticide residue FVs was not significantly related to ART outcomes. Higher consumption of high-pesticide residue FVs was associated with lower probabilities of pregnancy and live birth following infertility treatment with ART. These data suggest that dietary pesticide exposure within the range of typical human exposure may be associated with adverse reproductive consequences.

    The aim of this study was to determine the effect of music therapy on the anxiety levels and pregnancy rates of women who underwent in vitro fertilization-embryo transfer. This prospective randomized controlled trial was conducted with 186 infertile women who presented to the In Vitro Fertilization Unit at the American Hospital in Turkey between April 2015 and April 2016. The infertile women who met the inclusion criteria were assigned to the music therapy group or the standard therapy group through block randomization. The study data were collected using the Personal Information Form, and State-Trait Anxiety Inventory. Early treatment success was determined by serum beta human chorionic gonadotrophin levels seven or ten days after the luteal day zero. For the analysis, descriptive statistics, chi-square test, Fisher's exact test, independent sample t-test were used. After the embryo transfer, the mean state anxiety scores decreased in both groups, and the mean trait anxiety score decreased in the music therapy group; however, the difference was not statistically significant (p>0.05). Clinical pregnancy rates did not differ between the music (48.3%) and standard (46.4%) therapy groups. After the two sessions of music therapy, state and trait anxiety levels decreased and pregnancy rates increased, but the difference was not significant. Therefore, larger sample sizes and more sessions are needed to evaluate whether music therapy has an effect on clinical outcomes. Copyright © 2017 Elsevier Inc. All rights reserved.

    This study was undertaken to compare success rates of vaginal birth after cesarean (VBAC) delivery, and uterine rupture as well as maternal/perinatal outcomes between women with preterm and term pregnancies undergoing trial of labor (TOL), and to compare maternal and neonatal morbidities in those women with preterm pregnancies undergoing a TOL versus repeat cesarean delivery without labor (RCD). Prospective 4-year observational study of women with a singleton gestation and a prior cesarean delivery at 19 academic centers. Clinical characteristics, maternal complications and VBAC delivery success for those with a preterm (24(0)-36(6) weeks) TOL, preterm RCD and term TOL (> or = 37 weeks) were analyzed. Among 3119 preterm pregnancies with prior cesarean delivery, 2338 (75%) underwent a TOL. 15,331 women undergoing TOL at term were also analyzed as a control group. TOL success rates for preterm and term pregnancies were similar (72.8% vs 73.3%, P = .64). Rates of uterine rupture (0.34% vs 0.74%, P = .03) and dehiscence (0.26% vs 0.67%, P = .02) were lower in preterm compared with term TOL. Thromboembolic disease, coagulopathy and transfusion were more common in women undergoing a preterm TOL than those at term. Among women undergoing a preterm TOL, rates of uterine dehiscence, coagulopathy, transfusion, and endometritis were similar to those having a preterm RCD. After controlling for gestational age at delivery and race, neonatal outcomes such as Neonatal Intensive Care Unit (NICU) admission, intraventricular hemorrhage, sepsis, and ventilatory support were similar in both groups except for a higher rate of respiratory distress syndrome in those delivered after a TOL. The likelihood of VBAC success after TOL in preterm pregnancies is comparable to term gestations, with a lower risk of uterine rupture. Perinatal outcomes are similar with preterm TOL and RCD. TOL should be considered as an option for women undergoing preterm delivery with a history of prior cesarean

    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 determine the rates of pregnancy complications following in vitro fertilization in comparison with those in a matched control group. A total of 13,543 deliveries at the Department of Obstetrics and Gynecology, University of Szeged, between January 1, 1995 and February 28, 2002 were subjected to retrospective analysis The 230 (1.7%) pregnancies following IVF-ET were evaluated and matched with spontaneous pregnancies concerning age, parity, gravidity, and previous obstetric outcome. Demographic and selected maternal characteristics, pregnancy and labor complications, and neonatal outcome were compared in the two groups The pregnancy complication rate was partly significantly higher among the singleton IVF-ET pregnancies. The obstetric risk was elevated, though not significantly concerning twin pregnancies. IVF-ET presents an additional obstetric risk. The neonatal outcome displays a significant difference only concerning an increased premature birth rate of singleton pregnancies. Triplet IVF-ET pregnancies involve a much higher risk of both pregnancy complications and neonatal outcome.

    Preterm birth, a leading cause of neonatal death, is more common in multiple births and thus there has being an increasing call for reducing multiple births in ART. However, few studies have compared risk factors for preterm births amongst ART and non-ART singleton birth mothers. A population-based study of 393,450 mothers, including 12,105 (3.1%) ART mothers, with singleton gestations born between 2007 and 2009 in 5 of the 8 jurisdictions in Australia. Univariable and multivariable logistic regression models were conducted to evaluate socio-demographic, medical and pregnancy factors associated with preterm births in contrasting ART and non-ART mothers. Ten percent of singleton births to ART mothers were preterm compared to 6.8% for non-ART mothers (P disadvantaged (12.4% in the lowest quintile vs 20.7%), less likely to be smokers (3.8% vs 19.4%), more likely to be first time mothers (primiparous 62.4% vs 40.5%), had more preexisting hypertension and complications during pregnancy. Irrespective of the mode of conception, preexisting medical and pregnancy complications of hypertension, diabetes and antepartum hemorrhages were consistently associated with preterm birth. In contrast, socio-demographic variables, namely young and old maternal age (34), socioeconomic disadvantage (most disadvantaged quintile Odds Ratio (OR) 0.95, 95% Confidence Interval (CI): 0.77-1.17), smoking (OR 1.12, 95%CI: 0.79-1.61) and priminarity (OR 1.19, 95% CI: 1.05-1.35, AOR not significant) shown to be associated with elevated risk of preterm birth for non-ART mothers were not demonstrated for ART mothers, even after adjusting for potential confounders. Nonetheless, in multivariable analysis, the association between ART and the elevated risk for singleton preterm birth persisted after controlling for all included confounding medical, pregnancy and socio-economic factors (AOR 1.51, 95% CI: 1.42-1.61). Preterm birth rate is approximately one-and-a-half-fold higher in ART mothers than non

    Full Text Available Introduction. Aim of the study was to find the effect of various prognostic factors in cases of unexplained infertility undergoing controlled ovarian stimulation (COS with intrauterine insemination (IUI. Methods. 146 cases of unexplained infertility were included. A maximum of 3 cycles of IUI were done with clomiphene citrate/HMG. Ovulation trigger was given when the largest follicle diameter was >18 mm, and IUI was planned 36 hours later. Luteal phase support was given for 15 days, urine pregnancy test was done on day 15, ultrasonography was done at 7 weeks, and pregnancy was followed up till delivery. Results. A total of 146 couples have undergone 239 cycles of IUI out of which 27 had UPT positive after 15 days. 14.8% had 1st-trimester abortion while 3.7% were ectopic. 86.3% were singleton pregnancies and 13.6% were twins. CPR was 11.29% per cycle and 18.4% per couple; LBR was 9.2% per cycle. Apart from duration of stimulation (p=0.037 and number of treatment cycles (p=0.045, no other factors had significant prognostic value. Conclusion. For unexplained infertility, IUI can be done to provide patients with the time that they need before moving on to IVF while providing a respectable chance of pregnancy.

    To compare maternal and perinatal outcomes after emergency cerclage with those after elective cerclage. In a retrospective review, data were assessed from women with a viable singleton pregnancy who underwent elective or emergency cerclage for cervical insufficiency at the Tongji Hospital, Wuhan, China, between January 2010 and July 2015. Subgroup analyses based on cervical length (CL; ≤15, 15-25, and 25-30 mm) were also conducted among women undergoing emergency cerclage. In total, 68 women underwent elective cerclage and 53 underwent emergency cerclage. The suture-to-delivery interval was significantly longer in the elective group (19.17 ± 5.86 weeks) than in the emergency group (11.29 ± 7.27 weeks; Ppregnancy length at delivery, frequency of Apgar score below 7 at 5 minutes (live births only), or birth weight (live births only). An inverse trend in the degree of CL shortening with pregnancy outcomes was observed; women with a CL of 25-30 mm had the best outcomes. Pregnancy outcomes were similar after emergency and elective cerclage. There was an inverse trend in the degree of CL shortening with pregnancy outcomes in the emergency cerclage group, with better outcomes observed for women with longer CL. © 2017 International Federation of Gynecology and Obstetrics.

  4. Mortality among twins and singletons in sub-Saharan Africa between 1995 and 2014: a pooled analysis of data from 90 Demographic and Health Surveys in 30 countries.

    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

    Research on cognitive and behavioural development of children born after assisted conception is inconsistent. This prospective study aimed to explore underlying causal relationships between ovarian stimulation, in-vitro procedures, subfertility components and child cognition and behaviour. Participants were singletons born to subfertile couples after ovarian stimulation IVF (n = 63), modified natural cycle IVF (n = 53), natural conception (n = 79) and singletons born to fertile couples (reference group) (n = 98). At 4 years, cognition (Kaufmann-ABC-II; total IQ) and behaviour (Child Behavior Checklist; total problem T-score) were assessed. Causal inference search algorithms and structural equation modelling was applied to unravel causal mechanisms. Most children had typical cognitive and behavioural scores. No underlying causal effect was found between ovarian stimulation and the in-vitro procedure and outcome. Direct negative causal effects were found between severity of subfertility (time to pregnancy) and cognition and presence of subfertility and behaviour. Maternal age and maternal education acted as confounders. The study concludes that no causal effects were found between ovarian stimulation or in-vitro procedures and cognition and behaviour in childrenaged 4 years born to subfertile couples. Subfertility, especially severe subfertility, however, was associated with worse cognition and behaviour. Copyright © 2016 Reproductive Healthcare Ltd. Published by Elsevier Ltd.

    A strong correlation between blastocyst morphology and implantation has been shown by many studies. The consequences and effects of assisted reproductive techniques on children's short and long-term health have always been a source of discussion. The obstetric and perinatal outcome of singletons according to blastocyst morphology has rarely been evaluated. The aim of this observational study is to determine whether a relationship exists between blastocyst morphology and obstetric and perinatal outcomes. A total of 799 singleton clinical pregnancies were analysed after transfer of a single fresh blastocyst on day 5 between 2006 and 2013. Blastocysts were divided into four groups based on their morphology on day 5: group 1 = good morphology blastocysts; group 2 = fair morphology blastocysts; group 3 = poor morphology blastocysts and group 4 = early (B1/B2) blastocysts. Obstetric and perinatal outcomes were compared between the four groups. After adjustment for some confounding variables, main obstetric and perinatal outcomes after transfer of blastocysts with poor morphological characteristics were not associated with increased adverse obstetric and perinatal events. Sex ratio was significantly higher in group 1 compared with groups 2, 3 and 4, and in Group 2 compared with Group 3 (P < 0.001) even after adjustment (P < 0.05).

    Intra-abdominal adhesions may result in an increased risk of major complications in case of a repeated cesarean section, such as bladder and bowel injury, hemorrhage, infection, and hysterectomy. In an attempt to predict intra-abdominal adhesions before a repeated cesarean delivery, we suggest the use of a novel technique employing a simple and feasible ultrasound imaging technique. The study included pregnant women who underwent one or more cesarean deliveries in their obstetric history and were evaluated during the third trimester of the ongoing pregnancy. In order to diagnose intra-abdominal adhesions, we used a sonographic sliding sign of the uterus under the inner part of the fascia of the abdominal muscles, and considered women 1) at high risk for severe adhesions in the absence of sonographic uterine sliding; or 2) at a low risk for severe adhesions in the presence of an obvious or moderate uterine sliding. A comparison between sonographic findings and intra-abdominal adhesions as evaluated by the surgeons during surgery was performed. We examined 63 patients with one or more previous cesarean delivery. Out of these 63 patients, 59 had completed the study and underwent repeated cesarean section at our Institution. In 16 out of the19 cases assigned to the high risk for severe adhesions group, the suspicion was confirmed at surgery, with a sensitivity of 76.2%. In addition, the suspicion for low risk for adhesions was confirmed in 35 out of 40 patients, with a specificity of 92.1%. The inter and intra-observer correlation using Cohen's Kappa (k) coefficient were 0.52 and 0.77 respectively. Our data show that a simple sonographic sign might predict both high and low risk for intra-abdominal adhesions in patients who underwent previous cesarean delivery. This technique may aid clinical decisions regarding repeated cesarean section approach. This article is protected by copyright. All rights reserved.

  9. Comparison of pain, cortisol levels, and psychological distress in women undergoing surgical termination of pregnancy under local anaesthesia versus intravenous sedation

    2007-06-01

    Full Text Available Abstract Background The weight of evidence suggests that women who freely choose to terminate a pregnancy are unlikely to experience significant mental health risks, however some studies have documented psychological distress in the form of posttraumatic stress disorder and depression in the aftermath of termination. Choice of anaesthetic has been suggested as a determinant of outcome. This study compared the effects of local anaesthesia and intravenous sedation, administered for elective surgical termination, on outcomes of pain, cortisol, and psychological distress. Methods 155 women were recruited from a private abortion clinic and state hospital (mean age: 25.4 ± 6.1 years and assessed on various symptom domains, using both clinician-administered interviews and self-report measures just prior to termination, immediately post-procedure, and at 1 month and 3 months post-procedure. Morning salivary cortisol assays were collected prior to anaesthesia and termination. Results The group who received local anaesthetic demonstrated higher baseline cortisol levels (mean = 4.7 vs 0.2, more dissociative symptoms immediately post-termination (mean = 14.7 vs 7.3, and higher levels of pain before (mean = 4.9 vs 3.0 and during the procedure (mean = 8.0 vs 4.4. However, in the longer-term (1 and 3 months, there were no significant differences in pain, psychological outcomes (PTSD, depression, self-esteem, state anxiety, or disability between the groups. More than 65% of the variance in PTSD symptoms at 3 months could be explained by baseline PTSD symptom severity and disability, and post-termination dissociative symptoms. Of interest was the finding that pre-procedural cortisol levels were positively correlated with PTSD symptoms at both 1 and 3 months. Conclusion High rates of PTSD characterise women who have undergone surgical abortions (almost one fifth of the sample meet criteria for PTSD, with women who receive local anaesthetic experiencing more

    To establish leukocyte count and differential percentiles in healthy singleton term laboring women during spontaneous normal vaginal labor following an uncomplicated pregnancy. An analysis of the records of all women (n = 762) who delivered at our delivery ward during a 2-month period was performed. After exclusion for cesarean delivery, induction of labor, pregnancy complications, preterm labor, multiple pregnancy, fever on admission, and lack of full blood count on admission, 365 parturient women during the 1st stage of labor were included in the final analysis. The total and differential leukocyte counts were determined by standard procedure by an automated cell counter. The leukocyte count range on admission to the delivery ward during the 1st stage of labor in healthy parturient women was between 4.4 × and 21.7 × 10(3)/µl and the 99th percentile limit was 20.06 × 10(3)/µl. The total leukocyte count was not influenced by cervical dilatation, ruptured membranes, or the presence and regularity of uterine contractions. An observed leukocyte count within the 99th percentile limit (20.06 × 10(3)/µl) in an otherwise normal parturient woman is reassuring in the absence of other clinical evidence. © 2014 S.

The database of spatio-temporal image correlation (cardio-STIC) was assessed to obtain the volume data sets for offline analysis. The volume data sets acquired at 16 to 38 weeks were measured for the thymus transverse diameter (TD) and the thymus/thoracic (TT) ratio at the three-vessel view. The measured values were regressed to identify the best-fitted model. A total of 622 volumes were successfully measured and the reference ranges of TD and TT ratio were established. Although TT was relatively constant or increased minimally with gestational age (GA), TD was significantly increased with gestational age. The predicted mean TD (mm) =  -31.206 + 2.854 × GA - 0.028 × GA 2 (r = 0.891; P thymus-associated conditions. For clinical purposes, we recommend measurements of the TD rather than TT ratio or perimeter because of its reproducibility and simplicity. © 2017 by the American Institute of Ultrasound in Medicine.

  13. Prevention of preterm delivery in twin pregnancy

    Rode, Line; Tabor, Ann

    2014-01-01

    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....

    Full Text Available Increased peripheral blood-activated NK cell counts are associated with increased risk of miscarriage and failed in vitro fertilization treatment. However, assessment of activated peripheral NK cells in normal and pathological pregnancies beyond implantation and early miscarriage has not been described. Total CD69 expressing NK cells counts were measured by flow cytometry in healthy women with singleton pregnancies, including 45 at 11+6–13+6 weeks’ gestation, 46 at 20+0–22+4 weeks, and 42 at 31+6–33+5 weeks. The number of peripheral blood NK cells decreased, whereas the percentage of activated CD69 expressing NK cells increased from the first to the third trimester of pregnancy. This study shows the course of peripheral blood NK cells and activated CD69 expressing NK cells in uncomplicated nulliparous singleton pregnancies. This is a first step in understanding their implication in pathological pregnancies.

    Maternal undernutrition around the time of conception is associated with an increased risk of insulin resistance in adulthood. We determined the effect of maternal undernutrition in the periconceptional period (PCUN, i.e., 60 days prior to 6 days after conception) and the preimplantation period (PIUN, i.e., 0-6 days after conception) on mRNA expression and protein abundance of key insulin-signaling molecules as well as the global microRNA expression in quadriceps muscle of singleton and twin fetal sheep in late gestation. In singleton fetuses, exposure to PCUN resulted in lower protein abundance of PIK3CB (P < 0.01), PRKCZ (P < 0.05), and pPRKCZ (Thr410) (P < 0.05) in skeletal muscle compared to controls. In PIUN singletons, there was a higher protein abundance of IRS1 (P < 0.05), PDPK1 (P < 0.05), and SLC2A4 (P < 0.05) compared to controls. In twins, PCUN resulted in higher protein abundance of IRS1 (P < 0.05), AKT2 (P < 0.05), PDPK1 (P < 0.05), and PRKCZ (P < 0.001), while PIUN also resulted in higher protein abundance of IRS1 (P < 0.05), PRKCZ (P < 0.001), and SLC2A4 (P < 0.05) in fetal muscle compared to controls. There were specific patterns of the types and direction of changes in the expression of 22 microRNAs in skeletal muscle after exposure to PCUN or PIUN and clear differences in these patterns between singleton and twin pregnancies. These findings provide evidence that maternal undernutrition around the time of conception induces changes in the expression of microRNAs, which may play a role in altering the abundance of the key insulin-signaling molecules in skeletal muscle and in the association between PCUN undernutrition and insulin resistance in adult life.

    2013-01-01

    OBJECTIVE The objective of the study was to examine the impact of chronic hypertension and pregestational diabetes on pregnancy outcomes. STUDY DESIGN This was a retrospective cohort study of 532,088 women undergoing singleton births in California in 2006. Women were categorized into chronic hypertension, pregestational diabetes, both, or neither. Pregnancy outcomes were compared using the χ2 test and multivariable logistic regression to control for potential confounders. RESULTS We identified differences in perinatal outcomes between the groups. The rate of preterm birth in women with both conditions was 35.5% versus 25.5% in women with chronic hypertension versus 19.4% in women with pregestational diabetes (P < .001). The rate of small for gestational age was 18.2% in women with both versus 18.3% in women with chronic hypertension versus 9.7% in women with pre-gestational diabetes (P <.001). CONCLUSION The impact of having both chronic hypertension and pregestational diabetes in pregnancy varies, depending on the outcome examined. Although some had an additive effect (eg, stillbirth), others did not (eg, preeclampsia). PMID:22892187

    2016-06-25

    To evaluate the prevalence of macrosomia in Beijing in 2013 and identify its risk factors. Retrospective six months analysis of 14 188 full-term singleton pregnant women from 15 hospitals with different levels in Beijing in 2013. Each participant's demographic data and medical information were collected individually by questionnaires. Multiple logistic regression analysis was used to examine the associations between variables and the risk of macrosomia. (1)The total prevalence of macrosomia was 7.069% (1 003/14 188) in Beijing in 2013. (2)The prevalence varied between the 15 hospitals, the lowest was 5.36% (89/1 659), while the highest reached 8.80%(46/523). Furthermore, the incidence of macrosomia was 1.284 times (95% CI: 1.114- 1.480, P=0.001) higher in the second graded hospitals than that in the tertiary hospitals. (3) Multiple logistic regression analyses showed that risk factors for macrosomia were maternal height≥160 cm (adjusted OR=1.875, 95% CI: 1.559- 2.256), pre-pregnant body mass index (p-BMI) ≥24.0 kg/m(2) (24.0- 27.9 kg/m(2): adjusted OR=1.696, 95% CI: 1.426- 2.018; p-BMI≥28.0 kg/m(2): adjusted OR=2.393, 95% CI: 1.831- 3.127), gestational weight gain (GWG) ≥15.9 kg (adjusted OR=2.462, 95% CI: 2.125- 2.853), gravidity>1 (adjusted OR=1.408, 95% CI: 1.224- 1.620), gestational weeks≥40 (adjusted OR=2.007, 95%CI: 1.745-2.308) and gestational diabetes mellitus (adjusted OR=1.522, 95%CI: 1.298-1.784). GWG≥15.9 kg, p-BMI≥28.0 kg/m(2) and gestational weeks≥40 were three risk factors that had the strongest associations with macrosomia (all Pmacrosomia in hospitals with different levels is obvious different. Gestational weeks, p-BMI and GWG are three main controllable risk factors for macrosomia, thus should receive more attentions.

    Our aim was to assess the long-term outcomes of infants born out of a pregnancy complicated by unexplained polyhydramnios. We retrospectively analysed a cohort of 173 singleton pregnancies with polyhydramnios. There were 24 singletons with unexplained polyhydramnios, defined as polyhydramnios where prenatal testing was negative. Infants were examined by a paediatrician at a median age of 12 months (range 12-64 months). Of the 24 infants, 19 (79%) had a normal outcome. West syndrome, polyuria and pulmonary stenosis were diagnosed in three children during follow up, while there were two perinatal deaths. Paediatric follow up of children born out of pregnancies complicated by unexplained polyhydramnios should be carried out systematically.

    Preterm twins have a higher morbidity rate of patent ductus arteriosus (PDA) than do singletons. However, the effect of multiple births on maturation of the ductus arteriosus (DA) has not been reported. Because intimal thickening (IT) is required for DA anatomical closure, we examined IT development in the DA of preterm twins and singletons. Sheep DA tissues obtained from preterm fetuses were subjected to elastica van Gieson staining to evaluate IT. The total IT score in each DA was the sum of the IT scores obtained from six evenly divided parts of the DA, which was positively correlated with gestational ages in singletons. Total IT scores were smaller in preterm twins than in singletons, although no difference in gestational age, birth weight, or gender ratio was observed. These data suggest that IT development of the DA is attenuated in sheep preterm twins, which may affect the higher morbidity of PDA.

    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.

    To examine the long term effects of low birth weight on academic achievements in twins and singletons and to determine whether the academic achievement of twins in early adulthood is inferior to that of singletons. Cohort study. Taiwanese nationwide register of academic outcome. A cohort of 218 972 singletons and 1687 twins born in Taiwan, 1983-5. College attendance and test scores in the college joint entrance examinations. After adjustment for birth weight, gestational age, birth order, and sex and the sociodemographic characteristics of the parents, twins were found to have significantly lower mean test scores than singletons in Chinese, mathematics, and natural science, as well as a 2.2% lower probability of attending college. Low birthweight twins had an 8.5% lower probability of college attendance than normal weight twins, while low birthweight singletons had only a 3.2% lower probability. The negative effects of low birth weight on the test scores in English and mathematics were substantially greater for twins than for singletons. The twin pair analysis showed that the association between birth weight and academic achievement scores, which existed for opposite sex twin pairs, was not discernible for same sex twin pairs, indicating that birth weight might partly reflect other underlying genetic variations. These data support the proposition that twins perform less well academically than singletons. Low birth weight has a negative association with subsequent academic achievement in early adulthood, with the effect being stronger for twins than for singletons. The association between birth weight and academic performance might be partly attributable to genetic factors.

    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).

    To study the efficacy and safety of preoperative intravenous tranexamic acid to reduce blood loss during and after elective lower-segment cesarean delivery. A single-blind, randomized placebo-controlled study was undertaken of women undergoing elective lower-segment cesarean delivery of a full-term singleton pregnancy at a center in Cairo, Egypt, between November 2013 and November 2014. Patients were randomly assigned (1:1) using computer-generated random numbers to receive either 1g tranexamic acid or 5% glucose 15 minutes before surgery. Preoperative and postoperative complete blood count, hematocrit values, and maternal weight were used to calculate the estimated blood loss (EBL) during cesarean, which was the primary outcome. Analyses included women who received their assigned treatment, whose surgery was 90 minutes or less, and who completed follow-up. Analyses included 100 women in each group. Mean EBL was significantly higher in the placebo group (700.3 ± 143.9 mL) than in the tranexamic acid group (459.4 ±7 5.4 mL; Pcesarean delivery.

    Objective: To assess whether light reflection rheography testing is affected by the changes that occur in the deep venous system of the lower limb in pregnancy and the puerperium. Methods: Twenty five women with a singleton pregnancy were recruited to undergo duplex Doppler ultrasound examinations of the common femoral vein to measure the vessel diameter and the blood flow velocity. Light reflection rheography testing was subsequently performed and the rate of venous emptying in the lower limb calculated. Serial measurements using both techniques were made at 15, 28, 36 weeks, and term gestation and at 2 days and 6 weeks postpartum. Results: Duplex Doppler ultrasound confirmed that there is progressive dilatation of the deep venous system in pregnancy, which reaches a maximum at term and reverses after delivery. There is an accompanying reduction in blood flow velocity, which reaches a nadir at term and increases after delivery. The rate of venous emptying as measured by light reflection rheography decreases with increasing gestation, but did not fall to a level consistent with venous occlusion by a deep venous thrombosis. Conclusions: Light reflection rheography has been shown to provide reliable results in pregnancy and the puerperium. Therefore, it is a potential tool for screening for deep venous thrombosis in this population.

    We investigated the association of human chorionic gonadotrophin (hCG) concentrations on a fixed day in very early pregnancy with development of hyperemesis gravidarum. This retrospective cohort study included 3107 singleton and 1265 twin pregnancies after in vitro fertilization treated at Department of Reproductive Medicine, Rikshospitalet, Oslo University Hospital, Norway in the period 1996-2013. Maternal serum hCG concentrations was measured on day 12 after embryo transfer. Information about development of hyperemesis gravidarum was obtained by individual linkage to the Medical Birth Registry of Norway. We studied hCG concentrations in very early pregnancy according to development of hyperemesis gravidarum, in singleton and twin pregnancies separately. We estimated the odds ratios for hyperemesis gravidarum with 95% confidence intervals according to quartiles of hCG concentrations. In twin pregnancies as compared to singleton pregnancies, we found higher mean maternal hCG concentrations (219 IU/L versus 130 IU/L, phyperemesis gravidarum (2.7% versus 1.4%, p=0.002 chi-squared test). However, both in singleton and in twin pregnancies, we found no significant difference in mean hCG concentrations between women who developed hyperemesis gravidarum and women who did not (Singletons: 122 IU/L versus 130 IU/L, p=0.504. Twins: 234 IU/L versus 219 IU/L, p=0.417 Student's t-test). We found no significant differences in odds ratios for developing hyperemesis gravidarum according to quartiles of hCG concentrations. We found no association of maternal hCG concentrations on a fixed day in early pregnancy with development of hyperemesis gravidarum. Copyright © 2017 Elsevier B.V. All rights reserved.

    Full Text Available The aim of this study was two-fold: to investigate the association of Assisted Reproductive Technology (ART and small newborn size, using standardized measures; and to examine within strata of fresh and cryopreserved embryos transfer, whether this association is influenced by parental infertility diagnoses. We used a population-based retrospective cohort from Michigan (2000-2009, Florida and Massachusetts (2000-2010. Our sample included 28,946 ART singletons conceived with non-donor oocytes and 4,263,846 non-ART singletons.Regression models were used to examine the association of ART and newborn size, measured as small for gestational age (SGA and birth-weight-z-score, among four mutually exclusive infertility groups: female infertility only, male infertility only, combined female and male infertility, and unexplained infertility, stratified by fresh and cryopreserved embryos transfer.We found increased SGA odds among ART singletons from fresh embryos transfer compared with non-ART singletons, with little difference by infertility source [adjusted odds-ratio for SGA among female infertility only: 1.18 (95% CI 1.10, 1.26, male infertility only: 1.20 (95% CI 1.10, 1.32, male and female infertility: 1.18 (95% CI 1.06, 1.31 and unexplained infertility: 1.24 (95% CI 1.10, 1.38]. Conversely, ART singletons, born following cryopreserved embryos transfer, had lower SGA odds compared with non-ART singletons, with mild variation by infertility source [adjusted odds-ratio for SGA among female infertility only: 0.56 (95% CI 0.45, 0.71, male infertility only: 0.64 (95% CI 0.47, 0.86, male and female infertility: 0.52 (95% CI 0.36, 0.77 and unexplained infertility: 0.71 (95% CI 0.47, 1.06]. Birth-weight-z-score was significantly lower for ART singletons born following fresh embryos transfer than non-ART singletons, regardless of infertility diagnoses.

    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.

    We describe a rare case of complete hydatidiform mole with twin live fetus (CHMTF) confirmed by histopathology, flow cytometry and polymerase chain reaction techniques. No malformations were observed, fetal karyotype was normal and β-human chorionic gonadotropin levels were high (>100,000 IU/ml). The patient was informed of the risks and decided to continue with the pregnancy, but at week 15, she had to undergo hysterectomy due to uterine rupture. She subsequently developed persistent trophoblastic disease (PTD) with pulmonary metastases that required treatment with polychemotherapy. Patients with CHMTF should be informed of all known risks, including the considerable risk of PTD, which is similar to or, even higher than that associated with a singleton complete mole. The risk does not appear to be increased by continuing the pregnancy. Because so few series have been published, there is a lack of evidence-based clinical management guidelines. To our knowledge, this is the first report of uterine rupture in CHMTF. © 2013 S. Karger AG, Basel.

    2010-01-01

    BACKGROUND: Exercise in pregnancy is recommended in many countries, and swimming is considered by many to be an ideal activity for pregnant women. Disinfection by-products in swimming pool water may, however, be associated with adverse effects on various reproductive outcomes. We examined...... the association between swimming in pregnancy and preterm and postterm birth, fetal growth measures, small-for-gestational-age, and congenital malformations. METHODS: We used self-reported exercise data (swimming, bicycling, or no exercise) that were prospectively collected twice during pregnancy for 74......,486 singleton pregnancies. Recruitment to The Danish National Birth Cohort took place 1996-2002. Using Cox, linear and logistic regression analyses, depending on the outcome, we compared swimmers with physically inactive pregnant women; to separate a possible swimming effect from an effect of exercise...

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).

    2017-01-01

    In 2014, in the United States, nearly 7% of newborns were twins. Congenital heart defects (CHDs) are more frequent in both monozygotic and dizygotic twins than in singletons. Still, the longer-term prognosis for CHD twins is unknown. Here we assess the mortality pattern for CHD twins up to age 36...... years and compare it with that for non-CHD twins, non-CHD co-twins, and CHD singletons. We identified all twins and a 5% random sample of all singletons born in Denmark from 1977 to 2009 by linking Danish national population and health registers. CHD cases were defined as subjects having a primary...... inpatient diagnosis of CHD (excluding preterm ductus) within the first year of life, and mortality was assessed through 2013. Among 63,362 live-born twin individuals, a total of 373 twins (0.59%) had a CHD diagnosis, whereas the corresponding numbers for singletons were 383 of 98,647 (0.39%). During...

    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.

    OBJECTIVE: To estimate the difference between levels of the two biochemical markers pregnancy-associated plasma protein-A (PAPP-A) and maternal serum free β-human chorionic gonadotropin (free β-hCG) in twin pregnancies relative to singleton pregnancies and establish an improved screening procedure...... for chromosomal abnormalities such as trisomy 21 in twin pregnancies. METHODS: 4843 unaffected and 47 trisomy 21-affected twin pregnancies were included in the study. Chorionicity-specific medians were generated for PAPP-A and free β-hCG from gestational ages 8 to 14 weeks. Multiple of the median values for each...... show a gestational age-specific increase relative to singleton medians. Allowing for gestation and chorionicity, twin pregnancies affected with trisomy 21 had higher levels of free β-hCG and lower levels of PAPP-A. Adding biochemistry into the risk assessment using a fixed risk cut-off of 1 in 100...

  17. Endocrinology of recurrent pregnancy loss.

    Science.gov (United States)

    Arredondo, Francisco; Noble, Luis S

    2006-02-01

    Following implantation, the maintenance of the pregnancy is dependent on a multitude of endocrinological events that will eventually aid in the successful growth and development of the fetus. Although the great majority of pregnant women have no pre-existing endocrine abnormalities, a small number of women can have certain endocrine alterations that could potentially lead to recurrent pregnancy losses. It is estimated that approximately 8 to 12% of all pregnancy losses are the result of endocrine factors. During the preimplantation period, the uterus undergoes important developmental changes stimulated by estrogen, and more importantly, progesterone. Progesterone is essential for the successful implantation and maintenance of pregnancy. Therefore, disorders related to inadequate progesterone secretion by the corpus luteum are likely to affect the outcome of the pregnancy. Luteal phase deficiency, hyperprolactinemia, and polycystic ovarian syndrome are some examples. Several other endocrinological abnormalities such as thyroid disease, hypoparathyroidism, uncontrolled diabetes, and decreased ovarian reserve have been implicated as etiologic factors for recurrent pregnancy loss.

    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 examine impact of cesarean delivery in first pregnancy on neonatal mortality and morbidity in second pregnancy. Retrospective cohort study using 1995-2002 US birth registration data. Neonatal mortality and morbidity in second pregnancy of cesarean deliveries in the first pregnancy were compared with vaginal deliveries in the first pregnancy. A total of 9,643,175 singleton second births were eligible in the analysis after excluding those with unknown delivery method (1,801,339 with a previous cesarean delivery and 7,841,836 with a previous vaginal delivery). Compared with vaginal delivery group, infants born to mothers with a previous cesarean delivery had increased risks of assisted ventilation (OR=1.47, 95% CI 1.46, 1.49), low Apgar's score (OR=1.14, 95% CI 1.12, 1.17), seizure (OR=1.36, 95% CI 1.27, 1.45), fetal distress (OR=1.46, 95% CI 1.44, 1.47), and asphyxia-related neonatal death (OR=1.40, 95% CI 1.29, 1.52). The association between mode of delivery in first pregnancy and neonatal outcomes in second pregnancy remained the same after excluding women with chronic health problems or adverse birth history and adjusting for potential confounding factors.

    Does cervical conization add an additional risk of preterm birth (PTB) in assisted reproduction technology (ART) singleton and twin pregnancies? Cervical conization doubles the risk of preterm and very PTB in ART twin pregnancies. ART and cervical conization are both risk factors for PTB. In this national population-based controlled cohort study, we included all ART singletons and twin deliveries from 1995 to 2009 in Denmark by cross-linkage of maternal and child data from the National IVF register and the Medical Birth register. Furthermore, control groups of naturally conceived (NC) singletons and twins were extracted. Cervical diagnoses were obtained from the Danish Pathology register. Cervical conization included both cold knife cone and LEEP (loop electrosurgical excision procedure) but not cervical biopsies. The main outcomes measures were PTB (PTB ≤ 37 + 0 gestational weeks), very preterm birth (VPTB ≤ 32 + 0 gestational weeks) and preterm premature rupture of membranes (PPROM). In all 16 923 ART singletons and 4829 ART twin deliveries were included. A random sample of NC singletons, 2-fold the size of the ART singleton group matched by date and year of birth (n = 33 835) and all NC twin deliveries (n = 15 112), was also extracted. Multiple logistic regression analyses were performed to adjust for the following confounders: maternal age, parity, year of child birth and sex of child. Cervical morbidity (dysplasia and conization) was more often observed in ART pregnancies (6.2% of ART singletons and 5.4% ART twins) than in NC pregnancies (4.2% for NC singletons and 4.5% for NC twins), both for singletons and twins. In ART singleton deliveries, the PTB rate was 13.1 versus 8.2% in women with and without conization, respectively, with an adjusted odds ratio (aOR) of 1.56 [95% confidence interval (CI) 1.21-2.01]. In ART twin deliveries, the prevalence of PTB was 58.2 versus 41.3% in women with and without conization, respectively, with an aOR 1.94 (95% CI 1

    2012-10-01

    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.

  4. Conformal Maxwell Theory as a Singleton Field Theory on $ADS_{5}$, IIB Three Branes and Duality

    CERN Document Server

    Ferrara, Sergio

    1998-01-01

    We examine the boundary conditions associated with extended supersymmetric Maxwell theory in 5-dimensional anti-De Sitter space. Excitations on the boundary are identical to those of ordinary 4-dimensional conformal invariant super electrodynammics. Extrapolations of these excitations give rise to a 5-dimensional topological gauge theory of the singleton type. The possibility of a connection of this phenomenon to the world volume theory of 3-branes in IIB string theory is discussed.

    This study was carried out to evaluate the perinatal outcomes of pregnancy with pregestational diabetes mellitus complicated by polyhydramnios. This was a retrospective study of singleton pregnancies, with an antepartum diagnosis of polyhydramnios, seen at the maternal fetal medicine department of Mater Mothers' Hospital, a tertiary-level facility. All pregnancies in women with pregestational diabetes with a singleton pregnancy beyond 24 weeks of gestation, from 1996 to 2006, were reviewed (n = 314), and pregnancies complicated by polyhydramnios were identified (n = 59). Pregnancy outcomes of women whose pregnancy was complicated with polyhydramnios were compared to those without this complication. The incidence of polyhydramnios in the study population was 18.8%. Women with polyhydramnios had increased hemoglobin A1c (HbA1c) levels throughout the pregnancy, and the difference was significant during the prepregnancy period and in the third trimester (P = 0.003 and P = 0.025, respectively). Significantly more mothers in the polyhydramnios group delivered preterm (54.2% vs. 33.3%, P = 0.004), the majority of which were iatrogenic preterm deliveries (44.1%). More pregnancies with polyhydramnios were delivered by Cesarean section (83.0% vs. 62%; P = 0.006), with the majority being performed electively in both groups (79.6% and 70.3%, respectively). Regardless, there were no significant differences in perinatal mortality rates, congenital abnormality rates, the incidences of low Apgar score, acidemia, hypoglycemia requiring intravenous therapy, phototherapy and ventilatory needs between the babies of the two groups. Pregestational diabetic pregnancy with polyhydramnios is associated with poor diabetic control. Despite this, there is no significant increase in adverse perinatal outcome in these pregnancies, apart from a higher iatrogenic preterm birth rate. (c) 2010 ISUOG.

    This paper proposes noisy speech recognition using hierarchical singleton-type recurrent neural fuzzy networks (HSRNFNs). The proposed HSRNFN is a hierarchical connection of two singleton-type recurrent neural fuzzy networks (SRNFNs), where one is used for noise filtering and the other for recognition. The SRNFN is constructed by recurrent fuzzy if-then rules with fuzzy singletons in the consequences, and their recurrent properties make them suitable for processing speech patterns with temporal characteristics. In n words recognition, n SRNFNs are created for modeling n words, where each SRNFN receives the current frame feature and predicts the next one of its modeling word. The prediction error of each SRNFN is used as recognition criterion. In filtering, one SRNFN is created, and each SRNFN recognizer is connected to the same SRNFN filter, which filters noisy speech patterns in the feature domain before feeding them to the SRNFN recognizer. Experiments with Mandarin word recognition under different types of noise are performed. Other recognizers, including multilayer perceptron (MLP), time-delay neural networks (TDNNs), and hidden Markov models (HMMs), are also tested and compared. These experiments and comparisons demonstrate good results with HSRNFN for noisy speech recognition tasks.

  7. The Singleton case: enforcing medical treatment to put a person to death.

    In October 2003 the Supreme Court of the United States allowed Arkansas officials to force Charles Laverne Singleton, a schizophrenic prisoner convicted of murder, to take drugs that would render him sane enough to be executed. On January 6 2004 he was killed by lethal injection, raising many ethical questions. By reference to the Singleton case, this article will analyse in both moral and legal terms the controversial justifications of the enforced medical treatment of death-row inmates. Starting with a description of the Singleton case, I will highlight the prima facie reasons for which this case is problematic and merits attention. Next, I will consider the justification of punishment in Western society and, in that context, the evolution of the notion of insanity in the assessment of criminal responsibility during the past two centuries, both in the US and the UK. In doing so, I will take into account the moral justification used to enforce treatment, looking at the conflict between the prisoner's right to treatment and his right to refuse medication where not justified by outcomes that can be reasonably expected to be positive for the individual. Finally, in contrast with some retributivist arguments in favour of enforced treatment to enable execution, I will propose a possible alternative, necessary if we are to consistently uphold the notion of autonomy.

    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.

    To study how reproductive risks and perinatal outcomes are associated with postpartum depression treated in specialised healthcare defined according to the International Classification of Diseases (ICD)-10 codes, separately among women with and without a history of depression. A retrospective population-based case-control study. Data gathered from three national health registers for the years 2002-2010. All singleton births (n=511 422) in Finland. Prevalence of postpartum depression and the risk factors associated with it. In total, 0.3% (1438 of 511 422) of women experienced postpartum depression, the prevalence being 0.1% (431 of 511 422) in women without and 5.3% (1007 of 18 888) in women with a history of depression. After adjustment for possible covariates, a history of depression was found to be the strongest risk factor for postpartum depression. Other strong predisposing factors for postpartum depression were fear of childbirth, caesarean birth, nulliparity and major congenital anomaly. Specifically, among the 30% of women with postpartum depression but without a history of depression, postpartum depression was shown to be associated with fear of childbirth (adjusted OR (aOR 2.71, 95% CI 1.98 to 3.71), caesarean birth (aOR 1.38, 95% CI 1.08 to 1.77), preterm birth (aOR 1.65, 95% CI 1.08 to 2.56) and major congenital anomaly (aOR 1.67, 95% CI 1.15 to 2.42), compared with women with no postpartum depression and no history of depression. A history of depression was found to be the most important predisposing factor of postpartum depression. Women without previous episodes of depression were at an increased risk of postpartum depression if adverse events occurred during the course of pregnancy, especially if they showed physician-diagnosed fear of childbirth.

    To assess the association of fertility treatment and subfertility with offspring intelligence, attention, and executive functions in 5-year-old singletons. Follow-up study. Denmark 2003-2008. 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 Objectives. This study aims to evaluate perinatal outcomes such as gestational age at delivery and live birth rate in singleton and twin gestation with or without fetal reduction. Method. A retrospective analysis was done on patients which were divided into reduced and unreduced groups on the basis of order of reduction of one or more fetuses between 6 and 13 weeks of gestation. Patients records were studied to note gestational age at delivery/abortion, birth weight, and neonatal outcome. Result. The cohort included a total of 292 patients: 102 singletons and 190 twins. 52 pregnancies were reduced in singleton cohort and 68 were reduced in twin cohort. No statistical difference was observed in live birth rate, gestational age at delivery, and birth weight and significant higher incidence of IUGR was observed in reduced and unreduced twin gestation. In singleton pregnancies however preterm delivery rate increased with fetal reduction. Conclusion. Although reduction does not reduce the live birth rate, it does reduce gestation age of delivery and birth weight of newborn. This effect is more apparent when multiple gestation is reduced to singleton.

    The placenta is responsible for the exchange of nutrients and for preventing harmful compounds from entering the fetal circulation. With increasing industrialization, exposures to commercial and toxic metals become a concern for both pregnant women and those planning a pregnancy. The understanding of transport mechanisms and pharmacokinetics for most inorganic elements is incomplete and limited to normal term deliveries. To obtain novel data on 46 inorganic elements in placentae from two high-risk obstetric populations, women carrying multiples and adolescents carrying singletons, evaluating differences, if present, and identifying predictors of placental content. Placental tissue was collected from adolescents carrying singletons and adults carrying multiples. Elemental content was analyzed using inductively coupled plasma-mass spectrometry (ICP-MS). Multivariate regression and factor analyses were used. With the exception of Au and Pt, almost all placentae contained quantifiable concentrations of each element analyzed. All placentae contained the essential elements Ca, Fe, Mg, Se and Zn, which clustered together onto the same factor. Most elements were higher in placentae from women carrying multiples. Differences in placental content disappeared after adjusting for maternal age. Rare earth elements (REEs) clustered together and remained higher in the multiples even after adjusting for maternal age. Human placentae contain a wide range of elements, including REEs. Ranges differed considerably between cohorts. Elements with similar chemical properties, like REEs or nutritionally essential elements, clustered together. Maternal age, and therefore longer environmental exposure, was significantly associated with elevated element concentrations in the placenta. Placental concentrations of several metals that are known to be nutritionally essential (e.g., Fe, Ca, Mg, and Zn) did not differ significantly between cohorts, suggesting tight regulation, whereas

  5. Universal cervical length screening for singleton pregnancies with no history of preterm delivery, or the inverse of the Pareto principle.

    Science.gov (United States)

    2017-06-01

    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.

    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.

    2016-12-01

    Full Text Available Introduction: Other than cesarean delivery, assisted vaginal delivery is an alternative procedure for delivery in emergency obstetrics. Presently, vacuum delivery has gained more popularity than forceps for operative/ assisted vaginal delivery, when and where indicated, with success as well as lesser neonatal and maternal complications. This study was done to estimate the short term maternal and fetal morbidity/mortality due to vacuum assisted vaginal delivery. Methods:  A prospective observational study was conducted at Lumbini Medical College Teaching Hospital from January 2015 to May 2016. One hundred and four pregnant women who had successful vacuum assisted vaginal deliveries were enrolled. Fetal and maternal outcome were assessed. Results: One hundred and four successful vacuum deliveries (2.9% were conducted among 3457 deliveries during our study period. Sixty seven (64.4% were primigravida and most (n=59, 56.7% parturients were of age group 20-30 years. The commonest (n=65, 62.5% indication for vacuum application was prolonged second stage of labor. The maternal morbidity variables were: 6.7% (n=7 had genital tract injury, 3.8% (n=4 had primary post-partum hemorrhage, 3.8% (n=4 had urinary retention, 2.8% (n=3 needed blood transfusion. Among neonatal morbidity indicators, 19.2% (n=20 neonates had birth asphyxia, 4.8% (n=5 neonates had cephalohematoma, 0.96% (n=1 had brachial plexus injury. There was one early neonatal death due to meconium aspiration syndrome. Conclusion: A successful vacuum assisted delivery can be achieved with lesser maternal and neonatal morbidity with timely assessment of labor, skilled operator, and availability of neonatal team.

    To construct reference charts and equations of fetal biometry for singleton pregnant women in Shaanxi, China. This was a cross-sectional study involving 6,832 singleton pregnant women. One set of fetal ultrasonographic measurement data between the 16th to 41st gestational weeks (GW) was randomly selected from each pregnant woman, and biparietal diameter (BPD), abdominal circumference (AC), and femur length (FL) were recorded. Mean and standard deviation (SD) of BPD, AC, and FL were fitted by polynomial. Centile = Mean + Z(alpha) x SD was used to calculate centiles. Differences in the 50th centile of BPD, AC, and FL between Hong Kong, Korean, Italian and Shaanxi fetuses were compared. Mean of BPD, AC, and FL were well-fitted by quadratic polynomial, SD of BPD, AC and FL were fitted by linear regression. Equations for estimating mean and SD for BPD, AC, and FL from GW were obtained. Centiles for BPD,AC, and FL were calculated. From the 21st GW, the differences in BPD,AC, and FL between Hong Kong, Korean, Italian, and Shaanxi fetuses became larger. Fetal biometry reference charts and equations for estimating fetal size and GW could be used in obstetrics practice and research in Shaanxi, China.

  12. Ectopic pregnancy.

    Science.gov (United States)

    Randall, S

    1986-12-01

    This discussion of ectopic pregnancy covers mortality, definition, etiology, diagnosis and management, and contraception. In the 1979-81 "Report on Confidential Enquiries into Maternal Deaths in England and Wales," ectopic pregnancy accounted for 11.4% of all maternal deaths. Avoidable factors were found in 64% of deaths from ectopic pregnancy, the most common being delay in diagnosis and operative intervention. Ectopic pregnancy is the implantation of the conceptus outside the uterus or in an abnormal location within the uterus. Tubal gestation invariably has a multifactorial etiology and occurs owing to delay in the transport of the fertilized ovum. Table 1 lists causes. Salpingitis is the main cause of tubal pregnancy and now is considered to be due primarily to chlamydia. The consequences of tubal surgery, for whatever reason, and hormonal treatment also are major etiological factors. Every woman of reproductive age, especially if she has 1 or more etiological factors in her past history, who presents with a history of a missed period and irregular vaginal bleeding or abdominal pain, must be considered to have an ectopic pregnancy until proved otherwise. Diagnosis still is essentially a clinical one. In difficult cases use should be made of radioimmunoassay of beta hCG, ultrasonic scanning, and laparoscopy. In 25% of cases, a correct diagnosis was made only at laparotomy. Culdocentesis and endometrial biopsy are of limited use. In cases of ruptured ectopic pregnancy with circulatory collapse, immediate operative intervention is essential. In regard to contraception, the combined oral contraceptive (OC), in suppressing ovulation and thickening the cervical mucus, has a protective effect. Method failure does not increase the incidence of extrauterline pregnancy above normal. The progestagen-only pill is associated with a small increase in the risk of an initial and recurrent ectopic pregnancy. It does not suppress ovulation and may affect tubal motility, but it

  14. Abdominal Cerclage in Twin Pregnancy after Radical Surgical Conization

    Directory of Open Access Journals (Sweden)

    Ioannis Kyvernitakis

    2014-01-01

    Full Text Available Radical and repeated cone biopsies are associated with a high risk of spontaneous preterm birth. A 30-year-old gravida 1 presented with a spontaneous dichorionic twin pregnancy. She had a history of two radical surgical conizations. By speculum examination, no cervical tissue was detected. A history-indicated transabdominal cervicoisthmic cerclage was performed at 12 + 4/7 gestational weeks because of assumed cervicoisthmic insufficiency. The pregnancy continued until 34 + 3/7 weeks when the patient developed preeclampsia indicating Cesarean delivery. Transabdominal cerclage in twin pregnancy has rarely been described, but it may be considered in case of extreme cervical shortening after radical cervical surgery, as it would in singleton pregnancy.

    To generate reference ranges for bioelectrical impedance indices throughout pregnancy and to investigate whether a relationship exists between these indices and the neonatal birth weight. Pregnant women with a singleton gestation, gestational age lower than 12 weeks, and absence of medical diseases before pregnancy were enrolled. Patients with pregnancy complications, such as hypertensive disorders, diabetes, and antiphospholipides syndrome were excluded. Antrophometric maternal parameters and bioelectrical impedance measurements were performed during the first, second, third trimester of pregnancy, at delivery and 60 days after delivery. Height(2)/resistance (cm(2)/Omega) and height(2)/reactance (cm(2)/Omega) were utilized to estimate the total and extracellular body water amounts, respectively. Spearman rank correlations and cox proportional hazard modelling were used for statistical purposes. 169 patients completed all measurements. Total and extracellular water amounts significantly increase as pregnancy advances and return to the pre-pregnancy values within 60 days after delivery. After adjustment for gestational age at delivery, fetal sex, and smoking habits, height(2)/resistance at 25 weeks (hazard=1.04, 95% confidence interval (CI) 1.02-1.06, Pweight. We have provided reference ranges for bioimpedance analysis during pregnancy, an easy, fast and non invasive method to estimate the body water composition during pregnancy. Bioelectrical impedance indices during the second trimester of pregnancy are independently related to the birth weight.

  16. Intrauterine shelves in pregnancy: sonographic observations.

    Science.gov (United States)

    Brown, D L; Felker, R E; Emerson, D S

    1989-10-01

    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.

    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.

  19. Managing epilepsy in pregnancy.

    Science.gov (United States)

    Thomas, Sanjeev V

    2011-01-01

    There are close to one and half million women with epilepsy (WWE) in reproductive age group in India. WWE have several unique gender-specific problems in the biological and social domains. Women experience more social stigma from epilepsy and have more difficulty with education and employment. They have more difficulty to get married and sustain successful family life. Reproductive hormones like estrogen and progesterone have opposing effect on seizure threshold. WWE have increased risk of infertility. About 10% of their babies may have major congenital malformations. Most of the adverse biological outcomes for WWE are related to adverse effects of antiepileptic drugs (AEDs). Traditional AEDs like phenobarbitone and sodium valproate are probably associated with increased risk of fetal malformations or other adverse fetal outcomes. Polytherapy and use of high dose of any AED is associated with higher risk fetal complications. It is very important that all WWE have a preconception evaluation done by a neurologist, when the need to continue AEDs or possibility of reducing AED load could be assessed. All WWE need to take folic acid 5 mg daily during preconception period and pregnancy. They should undergo a detailed screening for fetal malformations between 12 and 18 weeks of pregnancy. The neurologist, gynecologist, imageologist and pediatrician need to work as a team while managing pregnancy in WWE. It is important to reassure WWE and their relatives that pregnancy is safe in WWE and their children are healthy in more than 90% instances.

    2006-01-01

    After the confirmation of an intact interstitial pregnancy through sonographic diagnosis and laparoscopy, systemic and local methotrexate therapy is a well established conservative treatment to preserve the uterus. The parameters of successful treatment are the course of serum hCG value and sonographic changes. In this case series we describe sonographic monitoring under methotrexate (MTX) application and the residual sonographic findings after completing therapy. Three consecutive patients (two singleton and one twin pregnancy) with intact interstitial pregnancies were diagnosed and treated with MTX between 2000 and 2004. During the treatment we recorded the hCG values, maximum size of the interstitial lesion, vitality of the pregnancy, and vascularization. In all patients the sonographic diagnosis of an interstitial pregnancy was confirmed by laparoscopy. Following systemic MTX therapy, the hCG values normalised within 8 weeks in the singleton pregnancies and in 10 weeks in the twin pregnancy. During conservative therapy vascularization in the lesion withered continuously. The size of the primary myometrial lesion decreased at a slow rate and part of the lesion persisted in all three patients. Despite decreasing hCG levels, residual sonographic patterns of an interstitial ectopic pregnancy persist in the uterine wall.

    To evaluate maternal and fetal outcomes among women with hyperemesis gravidarum (HG). In a university hospital and a research and training hospital, a retrospective cohort study was conducted among women with singleton deliveries between 2003 and 2011. Maternal outcomes evaluated included gestational diabetes, pregnancy-induced hypertension, cesarean delivery. Neonatal outcomes also determined were 5-min Apgar score of less than 7, low birth weight, small for gestational age (SGA), preterm delivery, fetal sex, and stillbirth. There were no statistical differences in the mean of age, parity, the number of artificial pregnancy, and smoking between two groups. Infants from HG pregnancies manifested similar birth weight (3,121.5 ± 595.4 vs. 3,164 ± 664.5 g) and gestational age (38.1 ± 2.3 vs. 38.1 ± 2.6 weeks), relative to infants from the control group (p = 0.67 and 0.91, respectively). In addition, no statistical significant differences were found in the rates of SGA birth, preterm birth, gestational diabetes, pregnancy-induced hypertension, and adverse fetal outcome between two groups (p > 0.05). Cesarean delivery rates were similar in two groups (31.9% in hyperemesis group vs. 27% in control group, p = 0.49). Comparing the gender of the newborn baby and Apgar scores less than 7 at 5 min, there were no statistically significant differences between two groups (p = 0.16 and 0.42, respectively). Hyperemesis gravidarum is not associated with adverse pregnancy outcomes.

    Gustaf Rejnö

    Full Text Available BACKGROUND: Asthma is one of the most common chronic diseases, and prevalence, severity and medication may have an effect on pregnancy. We examined maternal asthma, asthma severity and control in relation to pregnancy complications, labour characteristics and perinatal outcomes. METHODS: We retrieved data on all singleton births from July 1, 2006 to December 31, 2009, and prescribed drugs and physician-diagnosed asthma on the same women from multiple Swedish registers. The associations were estimated with logistic regression. RESULTS: In total, 266 045 women gave birth to 284 214 singletons during the study period. Maternal asthma was noted in 26 586 (9.4% pregnancies. There was an association between maternal asthma and increased risks of pregnancy complications including preeclampsia or eclampsia (adjusted OR 1.15; 95% CI 1.06-1.24 and premature contractions (adj OR 1.52; 95% CI 1.29-1.80. There was also a significant association between maternal asthma and emergency caesarean section (adj OR 1.29; 95% CI 1.23-1.34, low birth weight, and small for gestational age (adj OR 1.23; 95% CI 1.13-1.33. The risk of adverse outcomes such as low birth weight increased with increasing asthma severity. For women with uncontrolled compared to those with controlled asthma the results for adverse outcomes were inconsistent displaying both increased and decreased OR for some outcomes. CONCLUSION: Maternal asthma is associated with a number of serious pregnancy complications and adverse perinatal outcomes. Some complications are even more likely with increased asthma severity. With greater awareness and proper management, outcomes would most likely improve.

  10. Excess Mortality in Patients Diagnosed With Hypothyroidism: A Nationwide Cohort Study of Singletons and Twins

    Science.gov (United States)

    Thvilum, Marianne; Brandt, Frans; Almind, Dorthe; Christensen, Kaare; Brix, Thomas Heiberg

    2013-01-01

    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.

    Short, J D; Slusher, I L

    1994-01-01

    Kentucky has the fourth highest percentage of infants born to teenage mothers in the US. Risk factors for adolescent pregnancy are poor academic performance, family history of adolescent pregnancy, absence of one or both biological parents in the home, troubled family relationships, family violence, history of substance abuse, and poor self-concept. Pregnancy adds new developmental requirements to the continual developmental crisis of adolescence. Some of these developmental requirements are dealing with pregnancy and birth of a child and peer and family reactions and relationships. Pregnant teens are at high risk for anemia, preeclampsia, preterm delivery, and low birth weight infants. The health care team must assess the abilities, needs, practices, and priorities of teens. Nurses should promote health and positive health practices in teens. They should focus on prevention of adolescent pregnancy and on meeting the needs of pregnant teens. Adolescent pregnancy interventions include education and adolescent-centered special programs. Peer groups, role playing, videos, and computer games are individualized and effective education techniques for teens. Formal adolescent pregnancy prevention programs are abstinence education, knowledge-based programs, and clinic-focused or school-based programs. A combination of approaches is more effective than using just one approach. Adolescent pregnancy prevention interventions should promote the value of education, discourage substance abuse, and provide counseling for victims of child abuse. Pregnant teens should receive prenatal care as soon as possible. One health care agency should combine physical care, psychosocial support, and education for teens. Kentucky schools help pregnant teens continue their education and help them obtain information and support for care for themselves and their babies. Nurses can be effective at reducing the number of unwanted teen pregnancies.

    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

    This study examined maternal and neonatal outcomes that are associated with pancreatitis in pregnancy, in particular preeclampsia. We conducted a retrospective cohort study of all singleton nonanomalous pregnancies in California from 2005-2008 with an identification of all cases of pancreatitis. Outcomes of interest included preeclampsia, intrauterine fetal death, preterm delivery, and neonatal or infant death. Univariate and multivariable analyses were then conducted to examine the association of pancreatitis in pregnancy and maternal characteristics and fetal outcomes. Our cohort of 2,039,870 pregnant women included 342 women (0.017%) with pancreatitis. Pancreatitis in pregnancy was not associated significantly with neonatal or infant death.

    Adolescent pregnancy, although on the decline, represents a significant public health concern. Often adolescents present late to prenatal care, either from lack of knowledge, fear of consequences, limited access, stigma, or all of the above. Although multifaceted, there are many risks both to mother and child that are increased in adolescent pregnancy. Many are unintended and are at risk for repeat adolescent pregnancy, especially within the first 2 years. Risks include but are not limited to: low birth weight, preterm delivery, stillbirth, and preeclampsia, as well as feelings of social isolation, delayed or neglected educational goals, and maternal depression.

    To examine the effect of pregnancy history on the risk of stillbirth. In a population-based cross-sectional study, data were reviewed from all women aged at least 20 years with singleton pregnancies in Finland between 2000 and 2010. The primary outcome-stillbirth-was defined as fetal death after 22 gestational weeks or death of a fetus weighing at least 500 g. Among 604 047 singleton pregnancies, the prevalence of stillbirth was 3.17 per 1000 deliveries. Prevalence was lowest for multiparous women without previous pregnancy loss after adjusting for major pregnancy complications associated with stillbirth (placenta previa, placental abruption, and pre-eclampsia) and other confounders. Relative to these women, stillbirth prevalence was higher among multiparous women with previous spontaneous abortion and/or stillbirth (adjusted odds ratio [aOR] 1.20, 95% confidence interval [CI] 1.05-1.36), nulliparous women with no previous pregnancy loss (aOR 1.23, 95% CI 1.10-1.38), and nulliparous women with prior spontaneous abortion (aOR 1.43, 95% CI 1.18-1.74). Previous pregnancy loss was found to be an independent risk factor for stillbirth, irrespective of the number of prior deliveries. © 2017 International Federation of Gynecology and Obstetrics.

    Full Text Available CONTEXT AND OBJECTIVE: As the rates of cesarean births have increased, the type of cesarean anesthesia has gained importance. Here, we aimed to compare the effects of general and spinal anesthesia on maternal and fetal outcomes in term singleton cases undergoing elective cesarean section.DESIGN AND SETTING: Prospective randomized controlled clinical trial in a tertiary-level public hospital.METHODS: Our study was conducted on 100 patients who underwent cesarean section due to elective indications. The patients were randomly divided into general anesthesia (n = 50 and spinal anesthesia (n = 50 groups. The maternal pre and postoperative hematological results, intra and postoperative hemodynamic parameters and perinatal results were compared between the groups.RESULTS: Mean bowel sounds (P = 0.036 and gas discharge time (P = 0.049 were significantly greater and 24th hour hemoglobin difference values (P = 0.001 were higher in the general anesthesia group. The mean hematocrit and hemoglobin values at the 24th hour (P = 0.004 and P < 0.001, respectively, urine volume at the first postoperative hour (P < 0.001 and median Apgar score at the first minute (P < 0.0005 were significantly higher, and the time that elapsed until the first requirement for analgesia was significantly longer (P = 0.042, in the spinal anesthesia group.CONCLUSION: In elective cases, spinal anesthesia is superior to general anesthesia in terms of postoperative comfort. In pregnancies with a risk of fetal distress, it would be appropriate to prefer spinal anesthesia by taking the first minute Apgar score into account.

    To compare the incidence of gestational diabetes mellitus (GDM) between pregnancies conceived spontaneously and pregnancies conceived following assisted reproductive technology (ART). This cross-sectional study evaluated the medical records of 215 women who conceived spontaneously and 145 women who conceived following ART from September 2011 to October 2012. Exclusion criteria were: polycystic ovary syndrome, maternal age ≥40 years, family history of diabetes in first-degree relatives, pre-pregnancy diabetes, glucose intolerance treated with hypoglycaemic agent (e.g. metformin), history of GDM, history of stillbirth, recurrent miscarriage, history of baby with birth weight ≥4kg (macrosomia), parity >3, Cushing syndrome, congenital adrenal hyperplasia and hypothyroidism. For better comparison of the incidence of GDM, the ART group was further subdivided into: (i) an in-vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) group (n=95); and (ii) an intrauterine insemination (IUI) group (n=50). The diagnosis of GDM was based on the criteria of the American Diabetes Association. The incidence of GDM was significantly higher in the IVF/ICSI and IUI groups (43% and 26%, respectively) compared with the spontaneous pregnancy group (10%). Age, pre-pregnancy body mass index (BMI) and weight gain in pregnancy were similar among women with GDM in all three groups. In addition, the incidence of pregnancy-induced hypertension was significantly higher in the IVF/ICSI group (21%) compared with the spontaneous pregnancy group (7%). Logistic regression analysis demonstrated four strong risk factors for GDM: age, BMI, mode of ART and progesterone use during pregnancy. This study indicated that the risk of GDM is two-fold higher in women with singleton pregnancies conceived following ART compared with women who conceived spontaneously. In addition, progesterone use during pregnancy was found to be an important risk factor for GDM. This subject requires further study

    The purpose of this study was to use a fixed reference to study movement (displacement) of the cervical internal os from the second to the third trimester in singletons and twins. The rationale was to gain insight into anatomic changes associated with cervical shortening. For each patient, 2 transperineal scans were performed 12 weeks apart (20 and 32 weeks). The internal os and symphysis pubis were visualized in the same field of view. Image registration techniques were used to align the 2 scans using the symphysis as a fixed reference. Total displacement, anterior displacement, and inferior displacement of the internal os were measured. Displacements were correlated with cervical shortening. Bland-Altman plots and interobserver intraclass correlation coefficients were calculated. A total of 42 healthy participants were studied: 28 with singletons and 14 with twins. The mean ± SD values for total displacement were 2.1 ± 1.2 and 2.0 ± 1.2 cm for singletons and twins, respectively (P = .75). The direction of displacement was significantly different. The mean anterior displacement was 1.1 cm greater for singletons than for twins (95% confidence interval, 0.29-2.0 cm, P = .01). Mean inferior displacement was 1.3 cm greater for twins than for singletons (95% confidence interval, 2.2-0.1 cm; P = .03). Only inferior displacement correlated with cervical shortening (P < .001; R(2) = 0.74). For every 2.2 cm of inferior displacement, the cervix shortened 1.0 cm. Assessments of reliability showed good agreement between 2 observers. The anatomic position of the internal cervical os depends on gestational age and fetal number. Cervical shortening correlated most strongly with inferior displacement.

    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.

    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.

    Placental GH is thought to be responsible for the rise in maternal IGF-I during pregnancy and is considered to be important for fetal growth. In this prospective longitudinal study of healthy pregnant women, we investigated determinants of placental GH in maternal serum. Serum was obtained from 455...... women with normal singleton pregnancies at approximately 19 and 28 wk gestation. Serum placental GH concentrations were measured by a highly specific immunoradiometric assay, and fetal size was measured by ultrasound. Data on birth weight, gender, prepregnancy body mass index (BMI), parity, and smoking...... habits were obtained from medical records. Serum placental GH concentrations were detectable in serum from all women as early as 14 wk gestation and increased during pregnancy in all individuals (P GH levels at second examination were found to be higher in women carrying female fetuses...

  16. Prenatal screening and diagnosis of aneuploidy in multiple pregnancies.

    Science.gov (United States)

    Gagnon, Alain; Audibert, Francois

    2014-02-01

    Prenatal screening for aneuploidy has changed significantly over the last 30 years, from being age-based to maternal serum and ultrasound based techniques. Multiple pregnancies present particular challenges with regards to screening as serum-based screening techniques are influenced by all feti while ultrasound-based techniques can be fetus specific. Tests currently available tend to not perform as well in multiple compared to singleton pregnancies. Considerations must be given to these variations when discussing and performing screening for aneuploidy in this situation. Prenatal invasive diagnosis techniques in multiple pregnancies bring their own challenges from a technical and counselling point of view, in particular with regards to sampling error, mapping and assignment of results and management of abnormal results. This review addresses these particular challenges and provides information to facilitate care. Copyright © 2013 Elsevier Ltd. All rights reserved.

    The objective of the study was to evaluate the ongoing risk of intrauterine fetal demise (IUFD) in nonanomalous pregnancies affected by polyhydramnios. We analyzed a retrospective cohort of all singleton, nonanomalous births in California between 2005 and 2008 as recorded in a statewide birth certificate registry. We included all births between 24+0 and 41+6 weeks' gestational age, excluding multiple gestations, major congenital anomalies, and pregnancies affected by oligohydramnios. Polyhydramnios was identified by International Classification of Diseases, ninth revision, codes. χ(2) tests were used to compare the dichotomous outcomes, and multivariable logistic regression analyses were then performed to control for potential confounders. We analyzed the data for pregnancies affected and unaffected by polyhydramnios. The IUFD risk was expressed as a rate per 10,000. The risk of IUFD in pregnancies affected by polyhydramnios was greater at every gestational age compared with unaffected pregnancies. The IUFD risk in pregnancies affected by polyhydramnios was more than 7 times higher than unaffected pregnancies at 37 weeks at a rate of 18.0 (95% confidence interval [CI], 9.0-32.6) vs 2.4 (95% CI, 2.0-2.5) and was 11-fold higher by 40 weeks' gestational age at a rate of 66.3 (95% CI, 10.8-68.6) vs 6.0 (95% CI, 5.1-6.3) in unaffected pregnancies. When adjusted for multiple confounding variables, the presence of polyhydramnios remained associated with an increased odds of IUFD in nonanomalous singleton pregnancies, with an adjusted odds ratio of 5.5 (95% CI, 4.1-7.6). Ongoing risk of IUFD is greater in low-risk pregnancies affected by polyhydramnios at all gestational ages compared with unaffected pregnancies with the greatest increase in risk at term. Although further study is needed to explore the underlying etiology of polyhydramnios in these cases, the identification of polyhydramnios alone may warrant increased antenatal surveillance.

    2015-07-01

    Is the risk of hypertensive disorders in pregnancies conceived following specific assisted reproductive technology (ART) procedures different from the risk in spontaneously conceived (SC) pregnancies? ART pregnancies had a higher risk of hypertensive disorders, in particular following cryopreservation, with the highest risk seen in twin pregnancies following frozen-thawed cycles. The risk of hypertensive disorders is higher in ART pregnancies than in SC pregnancies. The increased risk may be partly explained by multiple pregnancies and underlying infertility, but a contribution from specific ART procedures has not been excluded. Population-based cohort study, including sibling design with nationwide data from health registers in Sweden, Denmark and Norway. All registered ART pregnancies and a sample of SC pregnancies with gestational age ≥22 weeks from 1988 to 2007 were included. ART singleton pregnancies (n = 47 088) were compared with SC singleton pregnancies (n = 268 599), matched on parity and birth year. ART twin pregnancies (n = 10 918) were compared with SC twin pregnancies (46 674). We used logistic regression to estimate adjusted odds ratios and risk differences for hypertensive disorders in pregnancies following IVF, ICSI and fresh or frozen-thawed cycles. We also compared fresh and frozen-thawed cycles within mothers who had conceived following both procedures using conditional logistic regression (sibling analysis). Hypertensive disorders were reported in 5.9% of ART singleton and 12.6% of ART twin pregnancies. Comparing singleton pregnancies, the risk of hypertensive disorders was higher after all ART procedures. The highest risk in singleton pregnancies was seen after frozen-thawed cycles [risk 7.0%, risk difference 1.8%, 95% confidence interval (CI) 1.2-2.8]. Comparing twin pregnancies, the risk was higher after frozen-thawed cycles (risk 19.6%, risk difference 5.1%, 95% CI 3.0-7.1), but not after fresh cycles. In siblings, the risk was higher

    To determine factors associated with perception of pregnancy risk using a conceptual framework based on a review of the relevant literature and the psychometric model of risk perception. A correlational study. Ambulatory care and antepartum units of two tertiary hospitals and selected obstetricians' offices and prenatal classes in Winnipeg, Canada. A convenience sample of nulliparous women in their third trimester with a singleton pregnancy. Between December 2009 and January 2011, the following questionnaires were completed by 159 nulliparous women: the Perception of Pregnancy Risk Questionnaire, the Pregnancy-related Anxiety scale, Knowledge of Maternal Age-related Risks of Childbearing Questionnaire, the SF-12v2 Health Status Survey, the Multidimensional Health Locus of Control, and the Prenatal Scoring Form. Pearson's r correlations and stepwise multivariable linear regression analyses were conducted to achieve the research objectives. Of the eight proposed factors in the conceptual framework, five factors were significant predictors of perception of pregnancy risk, including pregnancy-related anxiety, maternal age, medical risk, perceived internal control, and gestational age, accounting for 47% to 49% of the variance in risk perception. An interaction between the pregnancy-related anxiety score and maternal age was found. These results contribute to the literature on perception of pregnancy risk by identifying a new predictor (gestational age), supporting the role of previously known factors in the state of pregnancy, and proposing pregnancy-related anxiety as a pregnancy dread factor in risk perception theories. This knowledge may have implications for developing more effective risk communication models. © 2013 AWHONN, the Association of Women's Health, Obstetric and Neonatal Nurses.

    We examined the clinical characteristics and obstetric outcomes in adolescent pregnancies in Japanese women. The present study was a retrospective investigation of all primiparous Japanese women with singleton pregnancies who gave birth at ≥22 weeks' gestation aged ≤18 years old (adolescent pregnancy, n = 325) and aged 28-30 years old (n = 2029) at Japanese Red Cross, Katsushika Maternity Hospital between 2002 and 2016. The frequencies of smoking, economic problems, an unmarried single status at delivery and the start of prenatal care in the first trimester in the adolescent pregnancy group were significantly higher than in the control group (p < .01). The incidences of Chlamydia trachomatis, Condyloma acuminatum, and mental disorders in the adolescent pregnancy group were significantly higher than in the control group (p < .01). Pregnancy in adolescence was not related to adverse obstetric outcomes except preterm delivery (p = .02). Adolescent pregnancy was not associated with adverse obstetric outcomes; however, adequate social, economic, and mental support is needed for adolescent pregnant women.

    Breastfeeding significantly benefits mothers and infants. We aimed to identify the determinants of its successful initiation. A retrospective study of 1893 mothers delivering healthy term singletons at a Swiss university hospital from 1/2008 to 3/2009 determined the associations between multiple breastfeeding and early postpartum parameters by univariate and multiple regression analysis. Multiparity was associated with nursing exclusively at the breast at discharge (Ppacifier use (P<0.05). Among obese mothers, nursing exclusively at the breast at discharge was less frequent, and use of all feeding aids more frequent, than among normal-weight women (both P<0.001). Neuraxial anesthesia was associated with use of maltodextrin and bottle (both P<0.05) compared to no anesthesia. Delayed first skin-to-skin contact and rooming-in for <24 h/day were each associated with maltodextrin and cup (P<0.05). Nursing exclusively at the breast at discharge was less frequent (P<0.001), and bottle use more frequent (P<0.05), in women with sore nipples than in those without. Obesity is a potent inhibitor of breastfeeding initiation. Delivery without anesthesia by a multiparous normal-weight mother, followed by immediate skin-to-skin contact, rooming-in for 24 h/day, and dedicated nipple care, provides the best conditions for successful early postpartum breastfeeding without the need for feeding aids or nutritional supplements

    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.

A retrospective study of institutional data on the mode of delivery and neonatal outcome. The study included two cohorts: 1998-1999 (n = 7437) and 2004-2005 (n = 8505), since the institutional cesarean section rate increased sharply between these cohorts and has remained stable after the latter study period. The caesarean section rate almost doubled from 6.8 to 11.3 % (p cesarean section rate from a low to a moderate does not improve the short-term neonatal outcome in term singleton pregnancies. On the contrary neonatal intensive care unit admissions increased with increasing caesarean section rate. Furthermore it is possible to achieve good neonatal outcome with a low cesarean section rate.

    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

    To evaluate whether vanishing twin (VT) pregnancies achieved by in vitro fertilization and intracytoplasmic sperm injection (IVF-ICSI) had a more adverse perinatal outcome than those after natural conception. Longitudinal, retrospective cohort study. Tertiary university hospital. Three hundred and six (78 after IVF-ICSI and 228 after natural conception) VT pregnancies over a 22-year period, with VT cases matched to primarily singleton controls. None. Obstetric and neonatal outcome data. The incidence of VT was statistically significantly higher after natural conception (18.2% of twins) than after IVF-ICSI (12.6% of twins). The odds of VT in pregnancies complicated with pregestational or gestational diabetes were disproportionally higher in IVF-ICSI cases than in spontaneously conceived VT pregnancies (adjusted odds ratio [AOR]: 0.80 vs. 3.10 and 1.00 vs. 1.07, respectively). Previous induced abortion (AOR 1.34) or second-trimester fetal loss (AOR 3.3) increased the risk of VT pregnancies after spontaneous conception. Gestational diabetes mellitus in both the previous (AOR 5.41) and the present (AOR 2.3) pregnancy as well as chronic maternal diseases (AOR 3.5) and placentation anomalies all represented independent risk factors for VT after IVF-ICSI. Vanishing twin pregnancies had a lower prevalence and a worse perinatal outcome after IVF-ICSI as compared with those of their spontaneously conceived counterparts.

    Despite the increasing prevalence of pregravid obesity, systematic evaluation of the association of maternal obesity with fetal growth trajectories is lacking. To characterize differences in fetal growth trajectories between obese and nonobese pregnant women, and to identify the timing of any observed differences. The Eunice Kennedy Shriver National Institute of Child Health and Human Development Fetal Growth Studies-Singletons study enrolled cohorts of pregnant women at 12 US health care institutions. Obese women (with prepregnancy body mass index > 30) and nonobese women (prepregnancy body mass indexes, 19-29.9) without major chronic diseases were recruited between 8 weeks and 0 days' gestation and 13 weeks and 6 days' gestation. A mixed longitudinal randomization scheme randomized participants into 1 of 4 schedules for 2-dimensional and 3-dimensional ultrasonograms to capture weekly fetal growth data throughout the remainder of their pregnancies. On each ultrasonogram, fetal humerus length, femur length, biparietal diameter, head circumference, and abdominal circumference were measured. Fetal growth curves were estimated using linear mixed models with cubic splines. Median differences in the fetal measures at each gestational week of the obese and nonobese participants were examined using the likelihood ratio and Wald tests after adjustment for maternal characteristics. The study enrolled 468 obese and 2334 nonobese women between 8 weeks and 0 days' gestation and 13 weeks and 6 days' gestation. After a priori exclusion criteria, 443 obese and 2320 nonobese women composed the final cohort. Commencing at 21 weeks' gestation, femur length and humerus length were significantly longer for fetuses of obese woman than those of nonobese women. Differences persisted in obese and nonobese groups through 38 weeks' gestation (median femur length, 71.0 vs 70.2 mm; P = .01; median humerus length, 62.2 vs 61.6 mm; P = .03). Averaged across gestation, head circumference

  13. Vitamin D deficiency in early pregnancy.

    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.

  7. Adolescent pregnancy.

    Science.gov (United States)

    1991-04-01

    Adolescent pregnancy poses health risks to both mother and child. For example, females 15 years old are more likely to die from pregnancy complications than older women. Adolescents often have poor eating habits, smoke, drink alcohol, and take drugs all of which can contribute to premature or prolonged labor. Further, these actions coupled with not seeking prenatal care during the 1st 3 months of pregnancy (70% of pregnant teenagers do not do so) increase the odds of having a low birth weight baby. These babies often have immature organ systems and problems regulating body temperature and blood sugar levels. They often are mentally retarded. Finally their mortality risk is significantly higher than that of normal weight babies. Teenage pregnancy often results in the mother dropping out of school thereby lacking job skills. Her income is 50% lower than that of women who wait to have their 1st child in their 20s. Even if a teenage mother weds, the couple most likely will divorce. Teenagers encounter much misinformation about sexuality at the same time that their sexual urge increases greatly. They often experiment with sex, sometimes under peer pressure, without using contraception resulting in unwanted pregnancies. Supportive and loving parents and/or an adult with whom they are comfortable can help them sort through their feelings and the confusion about sex. Parents should foster candid and open discussion about sex, sexually transmitted diseases, pregnancy, and contraception. It is important that teenagers know the difference between effective and ineffective contraceptives. They also need to discuss the advantages, disadvantages, and health risk of contraceptives with a physician or family planning counselor. County health departments, community family planning clinics, and family physicians all can help parents and/or adolescents learn more about responsible sexual behavior.

    Preterm birth is the leading cause of neonatal death and handicap in survivors. Although twins are found in 1.5% of pregnancies they account for about 25% of preterm births. Randomized controlled trials in singleton pregnancies reported that the prophylactic use of progestogens, cervical cerclage and cervical pessary reduce significantly the rate of early preterm birth. In twin pregnancies, progestogens and cervical cerclage have been shown to be ineffective in reducing preterm birth. The objective of this study was to test the hypothesis that the insertion of a cervical pessary in twin pregnancies would reduce the rate of spontaneous early preterm birth. This was a multicenter, randomized controlled trial in unselected twin pregnancies of cervical pessary placement from 20(+0)-24(+6) weeks' gestation until elective removal or delivery vs. expectant management. Primary outcome was spontaneous birth control groups in rates of spontaneous birth birth. Copyright © 2016 Elsevier Inc. All rights reserved.

    We reviewed the occurrence of prematurity, low birth weight, multiple gestations, frequency of stillbirths and maternity care-associated variables including hospital stay and hospital charges of women conceiving using assisted reproductive technology (ART) or artificial insemination (AI) compared with women with a history of infertility who conceived naturally, and all other naturally conceived pregnancies in California at non-federal hospitals between 2009 and 2011. At a single center, infants born after ART/AI were compared with infants provided care in the normal nursery. Publically available inpatient data sets from the California Office of Statewide Health Planning and Development for years 2009-2011 using data from all California non-federal hospitals were used to determine the impact of ART on a variety of pregnancy-related outcomes and infant characteristics. Infant data from a single center was used to determine hospital charges for infants delivered over an 18-month period to compare the hospital and physician charges indexed to similar charges for infants admitted to the 'normal' newborn nursery. Among ART/AI pregnancies, there was a 4-5-fold increase in stillbirths, compared with a 2-3-fold increase among women with infertility compared with other naturally conceiving women. ART/AI pregnancies underwent more cesarean sections (fourfold), and a near fourfold increase in the rate of preterm deliveries. Multiple gestations were increased 24-27-fold compared with naturally conceived pregnancies. Maternal hospital stay and hospital charges were increased among those undergoing ART/AI. Infant charges were increased multi-fold for singletons, twins and triplets delivered after ART/AI compared with naturally conceived infants. Multiple births, preterm births and a higher overall rate of fetal anomalies were found in California after ART/AI for 2009-2011.

    Is endometrial thickness measured prior to embryo transfer associated with placenta praevia? Following IVF, the risk of placenta praevia is increased 4-fold in women with an endometrial thickness of >12 mm compared with women with an endometrial thickness of women who had 4537 singleton assisted reproduction technology (ART) births occurring between January 2006 and June 2012 with no loss to follow-up. The primary outcome measure was the diagnosis of placenta praevia, made by the treating obstetrician on a transvaginal ultrasound in the third trimester. Women who had singleton births following single embryo transfer performed at Monash IVF in Melbourne, Australia were included. Of the 4537 cycles leading to a singleton ART birth, 2951 were stimulated cycles with fresh embryo transfers; 355 were hormone replacement therapy frozen embryo transfers and 1231 were natural cycles with frozen embryo transfers. The dataset was analysed using binary logistic general estimating equations to calculate odds ratios for placenta praevia adjusted (aOR) for known confounders. The study groups did not differ significantly in age, BMI and aetiologies of infertility prior to IVF treatment. When compared with stimulated cycles, placenta praevia was less common in women undergoing natural cycles with frozen embryo transfers (OR 0.44, 95% confidence interval (CI) 0.27-0.70, P women with an endometrial thickness of women with an endometrial thickness of 9-12 mm had an aOR of 2.02 (95% CI 1.12-3.65, P = 0.02) and women with an endometrial thickness >12 mm had an aOR of 3.74 (95% CI 1.90-7.34, P women with no previous births. The study is retrospective in nature, not all confounders may have been accounted for and details on previous intrauterine surgery, a known risk factor, were not available. In addition, ultrasound assessments were carried out by several highly trained operators measuring the endometrial thickness, the main independent variable, in a two-dimensional plane and some

    Objective  The objective of this study was to identify clinical factors predictive of appendicitis in pregnant women and associated obstetric outcomes. Study Design  We performed a single-center, retrospective cohort study of pregnant women who underwent magnetic resonance imaging for suspected appendicitis from 2007 to 2012. Rates and odds of appendicitis based on presenting signs and symptoms were estimated. We also estimated rates and odds of adverse obstetric outcomes among women with a diagnosis of appendicitis. Results  Of 171 pregnant women evaluated, 14 (8.2%) had pathology-confirmed appendicitis. White blood cell (WBC) count on admission was moderately predictive of appendicitis (area under the receiver operating characteristic curve, 0.74). A WBC count > 18,000 made the diagnosis of appendicitis more than 10 times more likely (adjusted odds ratio, 10.51; 95% confidence interval, 1.67-43.1). Of 127 women with complete pregnancy follow-up, women with appendicitis had a higher rate of pregnancy loss appendicitis. Appendicitis diagnosed in the first trimester was associated with increased risk of pregnancy loss  18,000 on admission is significantly associated with appendicitis in pregnant women undergoing evaluation for appendicitis. Appendicitis during the first trimester of pregnancy is associated with previable pregnancy loss. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

    Several modalities are currently utilized for diagnosis and therapy, by appropriate application of x-rays. In diagnostic radiology, interventional radiology, radiotherapy, interventional cardiology, nuclear medicine and other specialties radiation protection of a pregnant woman as a patient, as well as a member of the operating personnel, is of outmost importance. Based on radiation risk, the termination of pregnancy is not justified if foetal doses are below 100 mGy. For foetal doses between 100 and 500 mGy, a decision is reached on a case by case basis. In Diagnostic Radiology, when a pregnant patient takes an abdomen CT, then an estimation of the foetus' dose is necessary. However, it is extremely rare for the dose to be high enough to justify an abortion. Radiographs of the chest and extremities can be done at any period of pregnancy, provided that the equipment is functioning properly. Usually, the radiation risk is lower than the risk of not undergoing a radiological examination. Radiation exposure in uterus from diagnostic radiological examinations is unlikely to result in any deleterious effect on the child, but the possibility of a radiation-induced effect can not be entirely ruled out. The effects of exposure to radiation on the foetus depend on the time of exposure, the date of conception and the absorbed dose. Finally, a pregnant worker can continue working in an x-ray department, as long as there is reasonable assurance that the foetal dose can be kept below 1 mGy during the pregnancy. Nuclear Medicine diagnostic examinations using short-lived radionuclides can be used for pregnant patient. Irradiation of the foetus results from placental transfer and distribution of radiopharmaceuticals in the foetal tissues, as well as from external irradiation from radioactivity in the mother's organ and tissues. As a rule, a pregnant patient should not undergo therapy with radionuclide, unless it is crucial for her life. In Radiotherapy, the patient, treating

    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.

    Singleton-Merten syndrome (SMS) is an autosomal-dominant multi-system disorder characterized by dental dysplasia, aortic calcification, skeletal abnormalities, glaucoma, psoriasis, and other conditions. Despite an apparent autosomal-dominant pattern of inheritance, the genetic background of SMS and information about its phenotypic heterogeneity remain unknown. Recently, we found a family affected by glaucoma, aortic calcification, and skeletal abnormalities. Unlike subjects with classic SMS, affected individuals showed normal dentition, suggesting atypical SMS. To identify genetic causes of the disease, we performed exome sequencing in this family and identified a variant (c.1118A>C [p.Glu373Ala]) of DDX58, whose protein product is also known as RIG-I. Further analysis of DDX58 in 100 individuals with congenital glaucoma identified another variant (c.803G>T [p.Cys268Phe]) in a family who harbored neither dental anomalies nor aortic calcification but who suffered from glaucoma and skeletal abnormalities. Cys268 and Glu373 residues of DDX58 belong to ATP-binding motifs I and II, respectively, and these residues are predicted to be located closer to the ADP and RNA molecules than other nonpathogenic missense variants by protein structure analysis. Functional assays revealed that DDX58 alterations confer constitutive activation and thus lead to increased interferon (IFN) activity and IFN-stimulated gene expression. In addition, when we transduced primary human trabecular meshwork cells with c.803G>T (p.Cys268Phe) and c.1118A>C (p.Glu373Ala) mutants, cytopathic effects and a significant decrease in cell number were observed. Taken together, our results demonstrate that DDX58 mutations cause atypical SMS manifesting with variable expression of glaucoma, aortic calcification, and skeletal abnormalities without dental anomalies.

    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.

    Objective To examine how pre-pregnancy body mass index (BMI), parity, and pregnancy-related weight changes are associated with long-term risk of degenerative musculoskeletal conditions. Methods A total of 79,687 mothers with singleton births from the Danish National Birth Cohort were included....... Information on height and weight prior to pregnancy and 6 months postpartum as well as gestational weight gain (GWG) was obtained from telephone interviews, while parity was derived from the Danish Medical Birth Registry. Diagnoses of musculoskeletal conditions, including osteoarthritis, disc disorders, low...... of musculoskeletal conditions increased with both increasing pre-pregnancy BMI and increasing parity. Compared to normal-weight first-time mothers, the highest risk was seen in obese women with >2 births (HR 1.61 [95% confidence interval 1.41–1.83]). GWG of 10–15 kg was associated with the lowest risk...

    The literature presents conflicting results on the epigenetic effect of in vitro fertilization (IVF) on the short-term and mid-term growth of children. These contradictory results may be related to the use of heterogeneous methodologies and non-longitudinal data. The goal of this study was to compare the body mass index (BMI) of children conceived via IVF and spontaneous conception (SC) children, using longitudinal data from birth to 5 years. This study compared 118 singleton children born after in vitro fertilization, with or without intracytoplasmic sperm injection (ICSI), selected from a pre-existing single-center cohort to 320 SC children from the same geographic area. BMI and its evolution were analyzed using the mixed-effect model during three periods: before standing acquisition (from birth to 1 year of age), during standing acquisition, and the following period from 2 to 5 years of age. BMI means were not significantly different between groups regardless of the period, when adjusting for confounding factors related to parents, pregnancy, and children's characteristics and lifestyle. Nevertheless, during the standing acquisition period, children born after IVF-ICSI presented a less significant decrease in BMI (P<0.05). In addition, for each period we identified influencing factors (maternal BMI, level of wealth indicator) associated with BMI. In the study population, the suspected epigenetic influence of IVF reported in the literature was not observed for BMI from birth to 5 years of age. Further investigations need to be conducted to determine if the suspected influence of IVF on adiposity could be expressed through other parameters. Copyright © 2017 Elsevier Masson SAS.

    To identify risk factors for fear of childbirth (FOC) according to parity and socioeconomic status, and to evaluate associations between FOC and adverse perinatal outcomes. A cohort study. The Finnish Medical Birth Register. All 788 317 singleton births during 1997-2010 in Finland. Fear of childbirth was defined according to the International Classification of Diseases code O99.80, and its associations with several risk factors and perinatal outcomes were analysed by multivariable logistic regression. Prevalence of, risk factors for and outcomes of FOC. Fear of childbirth was experienced by 2.5% of nulliparous women and 4.5% of multiparous women. The strongest risk factors for FOC in nulliparous women were depression [adjusted odds ratio (aOR), 6.35; 95% confidence interval (CI), 5.25-7.68], advanced maternal age (aOR, 3.78; 95% CI, 3.23-4.42) and high or unspecified socioeconomic status. In multiparous women, the strongest risk factors for FOC were depression (aOR, 5.47; 95% CI, 4.67-6.41), previous caesarean section (CS) (aOR, 3.02; 95% CI, 2.93-3.11) and high or unspecified socioeconomic status. Among both nulliparous and multiparous women, FOC was associated with higher rates of CS (3.3-fold and 4.5-fold higher, respectively) and a lower incidence of low birthweight (depression are predisposing factors for FOC regardless of parity. Among multiparous women, a previous CS increases vulnerability to FOC. FOC is associated with increased rates of CS, but does not adversely affect other pregnancy outcomes. © 2014 Royal College of Obstetricians and Gynaecologists.

    Macrosomia, defined as a birthweight at least 4000 g, is a public health problem because of its adverse influences on maternal and neonatal outcomes. Studies show that there is an increasing prevalence of macrosomia births in developing countries. However, information on the epidemiology of macrosomia is limited in China. This study aimed to determine the prevalence and geographic variability of macrosomia in China and risk factors that can be targeted for intervention. A hospital-based, cross-sectional survey was conducted in 14 provinces in China, covering a wide range of geographic areas. The medical records of 101,723 singleton term infants born in 39 hospitals during 2011 were reviewed. Multiple logistic regression analysis was used to examine the associations between demographic characteristics and the risk of macrosomia. The total prevalence of macrosomia was 7.3%. The prevalence varied between provinces, ranging from 4.1% to 13.4%. The prevalence of macrosomia in northern China (8.5%) was significantly higher than that in southern China (5.6%). Logistic regression analyses showed that risk of macrosomia was positively associated with maternal age, pre-pregnant body mass index (BMI), gravidity, parity, maternal height, gestational weight gain (GWG), gestational diabetes mellitus (GDM), and male fetal sex. Maternal BMI, gestational week, and GWG were the three risk factors most strongly associated with macrosomia. The prevalence of macrosomia varied dramatically between different areas of China. High pre-pregnancy BMI and GWG represent main modifiable risk factors for macrosomia and need more attention from health care providers. © 2014 John Wiley & Sons Ltd.

    The International Commission of Radiology recommends a pregnancy screening test to all female patients of childbearing age who will undergo a radiological study. Radiation is known to be teratogenic and its effect is cumulative. The teratogenic potential starts at doses close to those used during these procedures. The prevalence of positive pregnancy tests in patients undergoing electrophysiological studies and/or catheter ablation in our midst is unknown. To evaluate the prevalence of positive pregnancy tests in female patients referred for electrophysiological study and/or radiofrequency ablation. Cross-sectional study analyzing 2,966 patients undergoing electrophysiological study and/or catheter ablation, from June 1997 to February 2013, in the Institute of Cardiology of Rio Grande do Sul. A total of 1490 procedures were performed in women, of whom 769 were of childbearing age. All patients were screened with a pregnancy test on the day before the procedure. Three patients tested positive, and were therefore unable to undergo the procedure. The prevalence observed was 3.9 cases per 1,000 women of childbearing age. Because of their safety and low cost, pregnancy screening tests are indicated for all women of childbearing age undergoing radiological studies, since the degree of ionizing radiation needed for these procedures is very close to the threshold for teratogenicity, especially in the first trimester, when the signs of pregnancy are not evident.

    There are geographic variations in fetal outcomes of adolescent pregnancies because of socio-economic differences between regions and countries. The aim of our study was to determine adverse fetal outcomes associated with adolescent pregnancies in Cameroon. A cross-sectional study to compare the outcomes of 268 singleton, adolescent pregnancies with 832 controls, delivered in four referral hospitals in Yaounde (Cameroon), between November 2004 and April 2005. The adverse fetal outcomes related to adolescent pregnancies were low birth weight (growth retardation were not significantly higher among adolescents. Adverse maternal outcome associated with adolescent pregnancies were eclampsia (OR, 3.18; CI, 1.21-8.32), preeclampsia (OR, 1.99; CI, 1.24-3.15), perineal tear (OR, 1.45; CI, 1.06-1.99) and episiotomy (OR, 1.82; CI, 1.20-2.73). Caesarean delivery, instrumental delivery and premature rupture of membranes were not significantly associated with adolescent pregnancy. Maternal factors associated with adverse fetal outcome in adolescents were maternal age, number of prenatal visits Cameroon. Improving compliance with prenatal care could significantly reduce the frequency of adverse fetal outcomes in adolescent populations in Cameroon.

    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 compare perioperative and pregnancy outcome between women undergoing laparoscopic appendectomy and those undergoing open appendectomy during pregnancy for presumed acute appendicitis. A retrospective cohort study of all women undergoing appendectomy during pregnancy in a tertiary referral medical center from 2000 to 2009. Outcome was compared between those undergoing laparoscopic appendectomy and those undergoing open appendectomy. Overall, 83,510 deliveries occurred during the study period, 85 (0.10%) were eligible for the study group. Of these, 26 (31%) had a laparoscopic appendectomy and 59 (69%) had an open appendectomy. No significant difference was found in the general, delivery and neonatal outcome characteristics between the two groups. There was a significant difference in the mean gestational age at surgery between laparoscopic appendectomy and the open appendectomy groups (14.6 versus 19.3 weeks respectively, p = 0.009). Post-operative complications (fever >38.0 °C or the presence of uterine contractions) rate was higher in the open appendectomy compared to the laparoscopic appendectomy group (25.5% versus 3.8%, respectively, p = 0.009). Laparoscopic appendectomy appears to be a safe procedure for presumed acute appendicitis during pregnancy with less post-operative complications as compared to open appendectomy.

    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 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

    The incidence of pregnancy in patients with chronic kidney disease (CKD) undergoing hemodialysis is rare. Forpregnant patients with CKD undergoing regular hemodialysis, the effects of renal disease on the fetus should be noted and require specific strategies. A 30-year-old woman had no menstruation for 4 months. Abdominal ultrasound showed single fetus within 16 weeks of pregnancy. She had previously been in regular hemodialysis twice a week since 2015, then the frequency of hemodialysis was increased to thrice a week for 4 hours/dialysis. During pregnancy, she was given erythropoiesis stimulating agent, controlled protein nutrition (0.6-1.5g/kg/day) and routine pregnancy controls to an obstetrician. After 31-32 weeks gestation, thebaby was born alive with low birth weight (1800g). Maintaining pregnancy in women with regular hemodialysis is still challenging and difficult. Prolonged/intensive dialysis during pregnancy results in longer gestational periods, higher fetal weights, and a higher likelihood of survival. Based on a dialysis guideline for pregnancy in CKD, hemodialysis is performed at least 20 hours/week to maintain pre-dialysis of BUN≤50mg/dl hemoglobin should be at least 10-11g/dL. We reported a case of pregnancy in dialysis CKD patient undergoing hemodialysis thricea week (4 hours/dialysis). The baby was born alive with low birth weight (1800 g).

Serum 25(OH)D concentrations were measured at 11-14 weeks' gestation in 229 singleton pregnancies using liquid chromatography-tandem mass spectrometry. The median serum 25(OH)D concentration was 10.8 ng/mL and 45.9% of women had severe vitamin D deficiency with concentrations of vitamin D deficiency was observed in early pregnancy which was related to dress code, use of multi-vitamins and season at sampling. Low 25(OH)D levels were not related with adverse pregnancy outcomes. Women with severe vitamin D deficiency were more likely to deliver vaginally.

    OBJECTIVE: The objective of this study is to investigate the effect of maternal obesity on fetal size in first- and second-trimester pregnancies and to determine duration of pregnancy as estimated by a variety of methods. METHODS: Between 2006 and 2011, a cohort study included (n = 9055) singleton...... pregnancies that resulted in live birth at Holbaek Hospital in Denmark. This study recorded first- and second-trimester fetal measurements and maternal anthropometry. Characteristics considered included mother's age, parity, height, body mass index (BMI), smoking habits, and sex of child. The correlation...... between BMI and duration of pregnancy was analyzed by time-to-event analysis and accounted for medical intervention by censoring while correlation of BMI on fetal size was evaluated by multiple regression analysis. RESULTS: Adjusting for maternal and fetal characteristics, BMI was associated...

    Background Previous studies of air pollution and birth outcomes have not evaluated whether complicated pregnancies might be susceptible to the adverse effects of air pollution. We hypothesized that trimester mean pollutant concentrations would be associated with fetal growth restriction, with larger risks among complicated pregnancies. Methods We used a multiyear linked birth certificate and maternal/newborn hospital discharge dataset of singleton, term births to mothers residing in New Jersey at the time of birth, who were White (non-Hispanic), African American (non-Hispanic), or Hispanic. We defined very small for gestational age (VSGA) as a fetal growth ratio pregnancy complications. Results We found significantly increased risk of SGA associated with 1st and 3rd trimester PM2.5, and increased risk of VSGA associated with 1st, 2nd, and 3rd trimester NO2 concentrations. Pregnancies complicated by placental abruption and premature rupture of the membrane had ~2-5 fold greater excess risks of SGA/VSGA than pregnancies not complicated by these conditions, although these estimates were not statistically significant. Conclusions These findings suggest that ambient air pollution, perhaps specifically traffic emissions during early and late pregnancy and/or factors associated with residence near a roadway during pregnancy, may affect fetal growth. Further, pregnancy complications may increase susceptibility to these effects in late pregnancy. PMID:19359274

  3. Maternal weight and body composition in the first trimester of pregnancy.

    2012-02-01

    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.

  4. Smoking during pregnancy and hyperactivity-inattention in the offspring

    Obel, Carsten; Linnet, Karen Markussen; Henriksen, Tine Brink

    2009-01-01

    BACKGROUND: Prenatal exposure to smoking has been associated with Attention Deficit Hyperactivity Disorder (ADHD) in a number of epidemiological studies. However, mothers with the ADHD phenotype may 'treat' their problem by smoking and therefore be more likely to smoke even in a society where...... smoking is not acceptable. This will cause genetic confounding if ADHD has a heritable component, especially in populations with low prevalence rates of smoking since this reason for smoking is expected to be proportionally more frequent in a population with few 'normal' smokers. We compared...... the association in cohorts with different smoking frequencies. METHODS: A total of 20 936 women with singleton pregnancies were identified within three population-based pregnancy cohorts in Northern Finland (1985-1986) and in Denmark (1984-1987 and 1989-1991). We collected self-reported data on their pre...

    Pregnancy in a woman with Systemic Lupus Erythematosus (SLE) can be complicated by both lupus activity and pregnancy mishaps. The majority of recent studies demonstrate an increase in lupus activity during pregnancy, perhaps exacerbated by hormonal shifts required to maintain pregnancy. Increased lupus activity, in turn, prompts an elevated risk for poor pregnancy outcomes, including stillbirth, preterm birth, low birth weight, and preeclamspsia. Fortunately, the majority of pregnancies in wo...

    1987-01-01

    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.

    The disease burden related to mental disorders and metabolic syndrome is growing in low-and middle-income countries (LMIC). The Colombo Twin and Singleton Study (COTASS) is a population-based sample of twins and singletons in Colombo, Sri Lanka. Here we present prevalence estimates for metabolic syndrome (metS) and mental disorders from a follow-up (COTASS-2) of the original study (COTASS-1), which was a mental health survey. In COTASS-2, participants completed structured interviews, anthropometric measures and provided fasting blood and urine samples. Depressive disorder, depressive symptoms, anxiety symptoms, post-traumatic stress disorder (PTSD) and hazardous alcohol use were ascertained with structured psychiatric screens (Composite International Diagnostic Interview (CIDI), Beck Depression Inventory (BDI-II), Generalised Anxiety Disorder Questionnaire (GAD-7), PTSD Checklist - Civilian Version (PCL-C), and Alcohol Use Disorders Identification Test (AUDIT)). We defined metS according to the International Diabetes Federation (IDF) criteria and the revised National Cholesterol Education Programme Adult Treatment Panel (NCEP ATP III) criteria. We estimated the prevalence of psychiatric disorders and metS and metS components, and associations with gender, education and age. Two thousand nine hundred thirty-four twins and 1035 singletons were followed up from COTASS-1 (83.4 and 61.8% participation rate, respectively). Prevalence estimates for depressive disorder (CIDI), depressive symptoms (BDI ≥ 16), anxiety symptoms (GAD-7 ≥ 10) and PTSD (PCL-C DSM criteria) were 3.8, 5.9, 3.6, and 4.5% respectively for twins and 3.9, 9.8, 5.1 and 5.4% for singletons. 28.1 and 30.9% of male twins and singletons respectively reported hazardous alcohol use. Approximately one third met the metS criteria (IDF: 27.4% twins, 44.6% singletons; NCEP ATP III: 30.6% twins, 48.6% singletons). The most prevalent components were central obesity (59.2% twins, 71.2% singletons) and

    2017-05-01

    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.

    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.

    Breast tissues undergo extensive physiologic changes during pregnancy, which may affect breast carcinogenesis. Gestational hypertension, preeclampsia/eclampsia, gestational diabetes, pregnancy weight gain, and nausea and vomiting (N&V) during pregnancy may be indicative of altered hormonal and metabolic profiles and could impact breast cancer risk. Here, we examined associations between these characteristics of a woman's pregnancy and her subsequent breast cancer risk. Participants were parous women that were recruited to a population-based case-control study (Western New York Exposures and Breast Cancer Study). Cases (n = 960), aged 35-79 years, had incident, primary, histologically confirmed breast cancer. Controls (n = 1,852) were randomly selected from motor vehicle records (pregnancy experiences. Multivariable-adjusted logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (CIs). N&V during pregnancy was inversely associated with breast cancer risk. Relative to those who never experienced N&V, ever experiencing N&V was associated with decreased risk (OR 0.69, 95% CI 0.56-0.84) as were increased N&V severity (p trend pregnancies (p trend pregnancies. Associations were stronger for more recent pregnancies (breast cancer subtype including estrogen receptor and HER2 expression status. Other pregnancy characteristics examined were not associated with risk. We observed strong inverse associations between pregnancy N&V and breast cancer risk. Replication of these findings and exploration of underlying mechanisms could provide important insight into breast cancer etiology and prevention.

  9. Spontaneous Heterotopic Pregnancy: Dual Case Report and Review of Literature

    2016-01-01

    Full Text Available Introduction. Heterotopic pregnancy is a rare complication usually seen in populations at risk for ectopic pregnancy or those undergoing fertility treatments. It is a potentially dangerous condition occurring in only 1 in 30,000 spontaneous pregnancies. With the advent of Assisted Reproduction Techniques (ART and ovulation induction, the overall incidence of heterotopic pregnancy has risen to approximately 1 in 3,900 pregnancies. Other risk factors include a history of pelvic inflammatory disease (PID, tubal damage, pelvic surgery, uterine Mullerian abnormalities, and prior tubal surgery. Heterotopic pregnancy is a potentially fatal condition, rarely occurring in natural conception cycles. Most commonly, heterotopic pregnancy is diagnosed at the time of rupture when surgical management is required. Case. This paper represents two cases of heterotopic pregnancies as well as a literature review. Conclusion. Heterotopic pregnancy should be suspected in patients with an adnexal mass, even in the absence of risk factors. Clinicians must be alert to the fact that confirming an intrauterine pregnancy clinically or by ultrasound does not exclude the coexistence of an ectopic pregnancy. A high index of suspicion in women is needed for early and timely diagnosis, and management with laparotomy or laparoscopy can result in a favorable and successful obstetrical outcome.

    To assess the effect of the combination of gestational diabetes mellitus (GDM) and pre-gravid obesity ('diabesity') in singleton gestations. We compared perinatal outcomes of singleton gestations in mothers with GDM and pre-gravid obesity, with GDM but with normal pre-gravid BMI, and obese mothers without GDM. We compared diabesity mothers (n = 1525, 24.4% of mothers with GDM, 9.9% of all obese women) to mothers with GDM but with normal BMI (n = 4704, 75.6% of mothers with GDM) and to obese mothers without GDM (n = 13,937, 90.1% of all obese mothers). Obesity, with and without GDM, increased the odds of having chronic hypertension whereas preeclampsia appears to be influenced by obesity only, as were the risk of births at 4000 g, low 5-min Apgar scores and NICU admissions. Obesity (without diabetes) is more frequently associated with adverse perinatal outcomes than diabesity or GDM in non-obese mothers. A campaign to decrease pre-gravid obesity should have at least the same priority as any campaign to control GDM.

    Summary Background To compare maternal and neonatal outcomes of term macrosomic and adequate for gestational age (AGA) pregnancies. Material/Methods A retrospective analysis was performed on all term singleton macrosomic (birth weight ≥4000 g) and AGA (birth weight >10th percentile and shoulder dystocia, neonatal hypoglycemia, and had longer hospitalization period (both in vaginal and cesarean deliveries). Specifically, the odds ratio (OR) relative to AGA pregnancies for each macrosomic category (4000–4250 g, 4250–4500 g and ≥4500 g) of shoulder dystocia was 2.37, 2.24, 7.61, respectively, and for neonatal hypoglycemia 4.24, 4.41, 4.15, respectively. The risk of post partum hemorrhage was statistically increased when birth weight was >4500 g (OR=5.23) but not for birth weight between 4000–4500 g. No differences were found in the rates of extensive perineal lacerations between AGA and the different macrosomic groups. Conclusions Macrosomia is associated with increased rate of cesarean section, shoulder dystocia, neonatal hypoglycemia, and longer hospitalization, but not associated with excessive perineal tears. Increased risk of PPH was found in the >4500g group. PMID:22936200

    2011-04-01

    Full Text Available Abstract Background Gestational Diabetes (GDM is one of the most common complications of pregnancies affecting around 7% of women. This clinical condition is associated with an increased risk of developing fetal macrosomia and is related to a higher incidence of caesarean section in comparison to the general population. Strong evidence indicating the best management between induction of labour at term and expectant monitoring are missing. Methods/Design Pregnant women with singleton pregnancy in vertex presentation previously diagnosed with gestational diabetes will be asked to participate in a multicenter open-label randomized controlled trial between 38+0 and 39+0 gestational weeks. Women will be recruited in the third trimester in the Outpatient clinic or in the Day Assessment Unit according to local protocols. Women who opt to take part will be randomized according to induction of labour or expectant management for spontaneous delivery. Patients allocated to the induction group will be admitted to the obstetric ward and offered induction of labour via use of prostaglandins, Foley catheter or oxytocin (depending on clinical conditions. Women assigned to the expectant arm will be sent to their domicile where they will be followed up until delivery, through maternal and fetal wellbeing monitoring twice weekly. The primary study outcome is the Caesarean section (C-section rate, whilst secondary measurement4s are maternal and neonatal outcomes. A total sample of 1760 women (880 each arm will be recruited to identify a relative difference between the two arms equal to 20% in favour of induction, with concerns to C-section rate. Data will be collected until mothers and newborns discharge from the hospital. Analysis of the outcome measures will be carried out by intention to treat. Discussion The present trial will provide evidence as to whether or not, in women affected by gestational diabetes, induction of labour between 38+0 and 39+0 weeks is an

    It is not fully known whether maternal prehypertension is associated with increased risk of adverse fetal outcomes, and it is debated whether increases in blood pressure during pregnancy influence adverse fetal outcomes. We performed a population-based cohort study in nonhypertensive women with term (≥37 weeks) singleton births (n=157 446). Using normotensive (diastolic blood pressure [DBP] risks of a small-for-gestational-age (SGA) birth or stillbirth. We further estimated whether an increase in DBP from early to late pregnancy affected these risks. We found that 11% of the study population had prehypertension in late pregnancy. Prehypertension was associated with increased risks of both SGA birth and stillbirth; adjusted odds ratios (95% confidence intervals) were 1.69 (1.51-1.90) and 1.70 (1.16-2.49), respectively. Risks of SGA birth in term pregnancy increased by 2.0% (95% confidence intervals 1.5-2.8) per each mm Hg rise in DBP from early to late pregnancy, whereas risk of stillbirth was not affected by rise in DBP during pregnancy. We conclude that prehypertension in late pregnancy is associated with increased risks of SGA birth and stillbirth. Risk of SGA birth was also affected by rise in DBT during pregnancy. Our findings provide new insight to the relationship between maternal blood pressure and fetal well-being and suggest that impaired maternal perfusion of the placenta contribute to SGA birth and stillbirth. © 2016 American Heart Association, Inc.

    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.

    Multiple pregnancy is a major complication of IVF and is associated with increased maternal, fetal and neonatal morbidity. Elective single embryo transfer (eSET) during IVF, rather than the more standard transfer of two embryos (double embryo transfer or DET), has been shown to significantly reduce the multiple pregnancy rate associated with IVF, while maintaining acceptable pregnancy rates. Couples undergoing IVF in 2008 who met good prognostic criteria had eSET performed. Pregnancy and twinning rates were compared with those for similar couples in 2007 who had DET. Couples unsuccessful with a fresh cycle of treatment had subsequent frozen embryo transfer cycles with DET. The cumulative pregnancy rate was similar for each group. However there were no multiple pregnancies in the eSET group, compared to 4 twins of 5 pregnancies in the DET group. 96% of eligible couples agreed to eSET. ESET is successful in and acceptable to good prognosis Irish couples undergoing IVF.

    We present the management of a case of failed medical and surgical management of second trimester pregnancy loss due to pregnancy in a non-communicating rudimentary horn. A 16-week intrauterine fetal death singleton pregnancy was referred to us after failed medical and surgical termination of pregnancy. Ultrasound confirmed the diagnosis and showed minimal blood clots and fluid in the pouch of Douglas. Laparoscopy showed a soft, enlarged right uterine horn not communicating with the cervix and containing the pregnancy, and a left uterine horn communicating with the cervix and showing a posterior wall perforation. The procedure was converted to laparotomy, and the right uterine horn and adjacent tube were excised. The patient made an uneventful recovery and was discharged after 3 days. Pregnancy in a non-communicating horn is rare and usually presents with serious complications. Any case of failed medical termination of pregnancy after repeated doses of misoprostol should be carefully assessed to exclude the possibility of uterine anomalies (especially in a primigravida), before proceeding with dilatation and evacuation to minimise the risk of complications.

    Birth size curves are needed for clinical and epidemiological purposes. We constructed birth weight (BW), length (BL), and head circumference (BHC) references, assessed effects of twinness and parity, and defined cut-off points for small, appropriate, and large for gestational age. Birth register data of all 753,036 infants born in 1996-2008 in Finland were cleaned to create references reflecting optimal intrauterine growth. The final data included 533,666 singletons and 15,033 twins (median gestation weeks (gws) 40.0 and 37.1, respectively, 41.6% primiparous). Sex-specific BW, BL, and BHC references were constructed from 23 to 43 gws separately for singletons and twins born to primiparous or multiparous mothers. GAMLSS method was used for modelling. In singletons from 36 gws onwards, increased BW and BL were observed in comparison to previous reference from 1979-1983. Twins diverged from singletons from 30 gws onwards. At 37.0 gws, mean BW was 400 g lower and mean BL 1.2 cm shorter than in singletons. From 30 gws onwards, birth size was larger in infants of multiparous than primiparous mothers. Population-based birth size references are available for the evaluation of birth size. Accounting for plurality and parity improves the accuracy of birth size evaluation.

  18. Liver disease in pregnancy

    Full Text Available Deranged liver function tests are encountered in 3% of pregnancies. The potential causes are classified as those unique to and those just incidental to pregnancy. Pregnancy-related diseases are the most frequent causes of liver dysfunction during pregnancy and exhibit a trimester-specific occurrence during pregnancy. Differentiation of liver dysfunction as that related to and just incidental to pregnancy is the key to management, especially when liver dysfunction is encountered after 28 weeks of pregnancy. It can be judged from the fact that delivery remains the cornerstone of management of pregnancy-related diseases except hyperemesis gravidarum. This is an overview of the causes of liver dysfunction during pregnancy; an update on the underlying mechanisms of their occurrence, especially liver diseases unique to pregnancy; and a methodological approach to their diagnosis and management.

    A survival-time regression model for gestational age at delivery with pre-eclampsia (PE) in singleton pregnancy, using maternal demographic characteristics and medical history, was reported previously. The objective of this study was to extend this model to dichorionic (DC) and monochorionic (MC) twin pregnancy. The study population included 1789 DC and 430 MC twin pregnancies and 93 297 singleton pregnancies. A survival-time model for gestational age at delivery with PE was developed from variables of maternal characteristics and medical history. The risk of PE with delivery pregnancies was determined and compared with that in singleton pregnancies. In singleton pregnancies comprising women of Caucasian racial origin, mean weight of 69 kg at 12 weeks' gestation, mean height of 164 cm, nulliparous, with spontaneous conception, no family history of PE and no history of diabetes mellitus, systemic lupus erythematosus or antiphospholipid syndrome, the mean of the Gaussian distribution of gestational age at delivery with PE was 55 weeks. In DC twins with PE, mean gestational age at delivery was shifted to the left by 8.2 (95% CI, 7.2-9.1) weeks and in MC twins it was shifted to the left by 10.0 (95% CI, 8.5-11.4) weeks. The risk of delivery with PE occurring at, or before, a specified gestational age is given by the area under the fitted distribution curve. For a reference population with the above characteristics, the estimated risk of PE history has been developed for estimation of patient-specific risks for PE in DC and MC twin pregnancy. Such estimation of the a-priori risk for PE is an essential first step in the use of Bayes' theorem to combine maternal factors with biomarkers for the continuing development of more effective methods of screening for the disease.

    2015-07-01

    It has recently emerged that carrying a male fetus is associated with poorer maternal β-cell function in pregnancy and an increased risk of gestational diabetes mellitus (GDM). β-cell dysfunction is the central pathophysiologic defect underlying both GDM and subsequent postpartum progression to type 2 diabetes mellitus (T2DM). This was a retrospective cohort study that aimed to determine whether fetal sex influences the natural history of maternal risk of diabetes after delivery and in a subsequent pregnancy. The study was conducted using population-based administrative databases in Ontario, Canada. All women with a singleton live-birth first pregnancy between April 2000 and March 2010 (n = 642 987) were included. Fetal sex was the exposure of interest (313 280 delivered a girl; 329 707 delivered a boy). Development of T2DM or a second pregnancy were the main outcome measures. Glucose tolerance in each pregnancy was classified as either GDM or non-GDM. The population was followed for a median of 3.8 years. Carrying a boy yielded a higher risk of GDM in both the first pregnancy (odds ratio [OR] =1.03; 95% confidence interval [CI], 1.0002-1.054) and second pregnancy (OR =1.04, 95% CI, 1.01-1.08). For women with GDM in the first pregnancy, the likelihood of developing T2DM before a second pregnancy was higher if they delivered a girl (OR = 1.07; 95% CI, 1.01-1.12). Recurrence of GDM was not affected by fetal sex (P = .7). However, among women with a non-GDM first pregnancy while carrying a girl, having a boy in their second pregnancy predicted an increased risk of GDM (OR = 1.07, 95% CI, 1.01-1.14). Fetal sex is a previously unrecognized factor that is associated with maternal diabetic risk both after delivery and in a subsequent pregnancy.

    To assess the perinatal outcome of teenage pregnancy in a large cohort and to determine risk factors for low birth weight (LBW) in teenage pregnancy. All singleton first deliveries to mothers of age 16-24 years between 1990 and 1997 were included. The deliveries were subdivided into three maternal age groups (16-17 and 18-19 compared to 20-24 years) and parameters of perinatal outcomes were compared. To adjust for potential confounding effects on the association between young maternal age and birth weight, logistic regression analysis was performed for LBW with maternal ethnicity, pregnancy-induced hypertension, lack of prenatal care and malformations of the newborn. Among a total of 11 496 patients, 600 (5.2%) were 16-17 years old, 2097 (18.2%) were 18-19 years old and the remaining 8799 (76.6%) were 20-24 years old. Bedouin ethnicity and lack of prenatal care were common in the youngest mothers. Rates of preterm delivery were 14.2%, 9.8% and 8.8% in the three age groups, respectively (p pregnancy-induced hypertension, operative delivery and Cesarean delivery were not significantly different among the three age groups. A multivariate analysis on LBW was performed to assess the unique contribution of young maternal age, adjusted for potential confounders. Adjusted ORs for LBW were 1.25 (95% CI 1.00-1.56) for maternal age pregnancy-induced hypertension, 1.55 (95% CI 1.30-1.84) for lack of prenatal care and 4.09 (95% CI 3.2-5.2) for malformations. Teenage pregnancy was found to be associated with adverse outcome such as LBW, preterm delivery, small for gestational age and malformations. The risk for LBW was affected mainly by demographic factors (maternal ethnicity, lack of prenatal care) and medical factors (pregnancy-induced hypertension, malformations).

    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

    Full Text Available Background Sleep disorder is one of the most common complaints of pregnancy that can lead to maternal and fetal complications. Objectives The main purpose of this study is to investigate the correlation between sleep disorders of pregnancy and abortion. Methods This study is conducted using a case-control method on 218 women in the age range of 18 - 35 years old with singleton-pregnancy passing their first or second pregnancy in Ahvaz, Iran. Continuous sampling was conducted on the basis of characteristics of the research unit. The case group (n = 109 included women hospitalized because of an abortion, and the control group (n = 109 consists of pregnant women above 22 weeks, who were referred to healthcare centers to get pregnancy cares. The data collection was done using a demographic questionnaire and pittsburgh sleep quality index (PSQI. Data analysis was performed using SPSS-22 and t-test for quantitative variables and Chi-Square for qualitative variables. Results Obtained results from the study showed that there is a significant relationship between abortion and sleep duration (P = 0.000, subjective sleep quality (P = 0.000, sleep latency (P = 0.000, habitual sleep efficiency (P = 0.000, sleep disturbances (P = 0.000, daytime dysfunction (P = 0.000, and total valued of sleep disorder (P = 0.000. However, the correlation was insignificant in case of use of sleeping medication (P = 0.233. Conclusions According to the obtained results, there is a significant correlation between sleep disorder and abortion. Therefore, training sleep health and suitable consultations during pregnancy would be effective in field of preventing abortion and with the aim of achieving to safe pregnancy.

    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 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.

    This study aimed to ascertain the frequency of polyhydramnios in singleton pregnancies, to determine the associated risk factors, and assess the adverse maternal and perinatal outcomes. A retrospective cohort study of all singleton pregnancies complicated with polyhydramnios after 28 weeks of gestation was carried out in Nizwa Hospital's Obstetrics & Gynecology Department, Oman, from January 2002 to December 2007. Of 25,979 pregnant women reviewed, 477 were found to have polyhydramnios. The control group consisted of 900 pregnant women. Cases of polyhydramnios were diagnosed as mild, moderate, or severe based on their highest amniotic fluid index. Cases were compared with controls in terms of demographic data; prevalence of diabetes, macrosomia, or Caesarean deliveries; frequency of fetal anomalies, and perinatal mortality rate. Polyhydramnios was diagnosed in 1.8% of pregnancies. It was mild in 382 (80%), moderate in 84 (17.6%), and severe in 12 (2.4%). A total of 72 (15.3 %) cases of polyhydramnios were complicated by diabetes (gestational or established diabetes mellitus) as compared to 10% of the control group and 39 (8.1%) neonates had congenital anomalies. Polyhydramnios was associated with advanced maternal age; 58 (12.2%) of subjects were over 40 years old. The perinatal mortality rate with polyhydramnios was 42 per 1,000 births compared to 14 per 1000 births in the control group. These data demonstrate that polyhydramnios is associated with an increased risk of adverse perinatal outcomes, and there is a significant positive relation with maternal age, diabetes, fetal anomalies, and fetal macrosomia.

    The visual system is able to detect targets according to a variety of criteria, such as by categorical (letter vs digit) or featural attributes (color). These criteria are often used interchangeably in rapid serial visual presentation (RSVP) studies but little is known about how rapidly they are processed. The aim of this work was to compare the time course of attentional selection and memory encoding for different types of target criteria. We conducted two experiments where participants reported one or two targets (T1, T2) presented in lateral RSVP streams. Targets were marked either by being a singleton color (red letter among black letters), being categorically distinct (digits among letters) or non-singleton color (target color letter among heterogeneously colored letters). Using event related potential (ERPs) associated with attention and memory encoding (the N2pc and the P3 respectively), we compared the relative latency of these two processing stages for these three kinds of targets. In addition to these ERP measures, we obtained convergent behavioral measures for attention and memory encoding by presenting two targets in immediate sequence and comparing their relative accuracy and proportion of temporal order errors. Both behavioral and EEG measures revealed that singleton color targets were attended much more quickly than either non-singleton color or categorical targets, and there was very little difference between attention latencies to non-singleton color and categorical targets. There was however a difference in the speed of memory encoding for non-singleton color and category latencies in both behavioral and EEG measures, which shows that encoding latency differences do not always mirror attention latency differences.

    To study the possible associations between advanced maternal age and risk of selected adverse pregnancy outcomes. The study used a nationwide cohort of 369,516 singleton pregnancies in Denmark followed from 11-14 weeks of gestation to delivery or termination of pregnancy. Pregnant women aged 35 years or older were divided into two advanced maternal age groups, 35-39 years and 40 years or older, and compared with pregnant women aged 20-34 years. Adverse pregnancy outcomes were chromosomal abnormalities, congenital malformations, miscarriage, stillbirth, and birth before 34 weeks of gestation. Multivariable logistic regression analyses were performed to investigate associations between advanced maternal age and adverse pregnancy outcomes. Furthermore, a risk prediction model for a composite adverse pregnancy outcome was made with prespecified predicting factors. Among the pregnant women aged 40 years or older, 10.82% experienced one or more of the selected adverse pregnancy outcomes compared with 5.46% of pregnant women aged 20-34 years (odds ratio [OR] 2.02, 99.8% CI 1.78-2.29). When pregnant women 40 years or older were compared with women aged 20-34 years, they had a higher risk of chromosomal abnormalities (3.83% vs 0.56%, OR 7.44 [CI 5.93-9.34]), miscarriage (1.68% vs 0.42%, OR 3.10 [CI 2.19-4.38]), and birth before 34 weeks of gestation (2.01% vs 1.21%, OR 1.66 [CI 1.23-2.24]), but no increased risk of congenital malformations and stillbirth. The risk prediction chart showed that advanced maternal age, use of assisted reproductive technology, nulliparous pregnancy, smoking during pregnancy, and obesity increased the absolute predictive risk of an adverse pregnancy outcome. Women older than 40 years have a higher risk of chromosomal abnormalities, miscarriage, and birth before 34 weeks of gestation than younger women and should be monitored accordingly. No increased risk was observed for stillbirth and other congenital malformations. Several factors increase the

    Children born with non-optimal birth characteristics - that is, are small for gestational age and/or preterm - have an increased risk for several long-term effects such as neurological sequelae and chronic disease. The purpose of this study was to examine whether twins exhibited a different outcome, compared with singletons, in terms of hospitalization during adolescence and early adulthood, and to what extent differences remain when considering the divergence in birth characteristics between singletons and twins. Persons born between 1973 and 1983 in Sweden and surviving until age 13 were included and followed until the end of 2006. Data on birth characteristics, parental socio-demographic factors, and hospitalizations were collected from national registers. Adjusting for parental socio-demographic factors, twins had a higher risk of being hospitalized than singletons (odds ratio, OR = 1.17, 95% confidence interval, CI = 1.10-1.25) and more often due to 'Congenital anomalies' (OR = 1.18, 95% CI = 1.06-1.28), 'Infections' (OR = 1.14; 95% CI = 1.08-1.20), 'External causes of illness' (OR = 1.10, 95% CI = 1.06-1.15), and 'Diseases of the nervous system' (OR = 1.18, 95% CI = 1.10-1.26). Stratifying for birth characteristics, this difference diminishes, and for some diagnoses non-optimal twins seem to do slightly better than non-optimal singletons. Thus, twins with non-optimal birth characteristics had a lower risk of hospitalization than non-optimal singletons on, for example, 'Congenital anomalies' and 'Diseases of the nervous system' (OR = 0.86, 95% CI = 0.77-0.96; OR = 0.88, 95% CI = 0.81-0.97, respectively) and Total (any) hospitalization (OR = 0.87, 95% CI = 0.83-0.92). Among those with optimal birth characteristics, twins had an increased hospitalization due to 'External causes of illness' (OR = 1.07, 95% CI = 1.02-1.13) compared with optimal singletons. Twins have higher hospitalization rates than singletons. In stratifying for birth characteristics, this

We report the cases of four pregnant women with cirrhosis treated in the gastroenterology and obstetrics-gynecology departments of the Lome Campus University Teaching Hospital between 2013 and 2015. The women's mean age was 32 years. Three were in the first trimester of pregnancy. Almost all had signs of advanced cirrhosis, including ascites (50%), lower-limb edema (75%), and jaundice (25%). All (100%) had liver failure and anemia. Cirrhosis was due to hepatitis virus B infection for 3 women. All had singleton pregnancies. Two mothers died; fetal outcome included one fetal loss and one stillbirth. This study shows the high risk associated with the combination of pregnancy and cirrhosis. Prognosis is poor for both mother and fetus.

    The combined effects of preterm delivery, small-for-gestational-age offspring, hypertensive disorders of pregnancy, placental abruption and stillbirth on early maternal death from cardiovascular causes have not previously been described in a large cohort. We investigated the effects of pregnancy...... complications on early maternal death in a registry-based retrospective cohort study of 782 287 women with a first singleton delivery in Denmark 1978-2007, followed for a median of 14.8 years (range 0.25-30.2) accruing 11.6 million person-years. We employed Cox proportional hazard models of early death from...... cardiovascular and non-cardiovascular causes following preterm delivery, small-for-gestational-age offspring and hypertensive disorders of pregnancy. We found that preterm delivery and small-for-gestational-age were both associated with subsequent death of mothers from cardiovascular and non...

    First-trimester screening for fetal aneuploidy using nuchal translucency (NT), pregnancy-associated plasma protein A, free or total beta-hCG, and maternal age constitutes a very effective screening test for fetal Down syndrome. We describe a case in which a patient presented at 14 weeks' gestation with an acute abdomen 1 week after first-trimester screening (including NT measurement) performed elsewhere, which was negative for trisomies 21 and 18. Sonographic examination revealed an interstitial pregnancy with a singleton fetus with present cardiac activity, which had not been noted 1 week earlier at the time of earlier transabdominal NT measurement. This case indicates that successful acquisition of a NT measurement during first-trimester screening for fetal aneuploidy does not negate the rare possibility of an unusual ectopic pregnancy. 2008 Wiley Periodicals, Inc.

    Maternal obesity is a major cause of obstetric morbidity and mortality. With surgical procedures to facilitate weight loss becoming more widely available and demanded and increasing number of women becoming pregnant after undergoing bariatric surgery, it is important and timely to consider the outcome of pregnancy following bariatric surgery. This paper aims to synthesize the current evidence regarding pregnancy outcomes after bariatric surgery. It concludes that bariatric surgery appears to have positive effects on fertility and reduces the risk of gestational diabetes and preeclampsia. Moreover, there appears to be a reduced incidence of fetal macrosomia post-bariatric procedure, although there remains uncertainty about the increased rates of small-for-gestational age and intrauterine growth restricted infants, as well as premature rupture of membranes in this group. A number of case reports highlight that pregnancy following bariatric surgery is not without complications and it must be managed as high risk by the multidisciplinary team.

    Objective The objective of this paper is to compare adverse pregnancy outcomes between normal pregnancies and pregnancies with systemic lupus erythematosus (SLE), particularly focusing on uncomplicated SLE with remission. Methods A retrospective cohort study was conducted by accessing the Maternal-Fetal Medicine (MFM) Unit database and the full medical records of the women. The records of singleton pregnancies with SLE and no underlying disease were assigned as the study group and their medical records were reviewed. The low-risk pregnancies were randomly selected as the controls. The adverse pregnancy outcomes were compared between the control group vs women with SLE, control group vs uncomplicated SLE, and between the subgroups within the study group. Results Of 28,003 births during the study period, 1400 controls and 140 pregnancies with SLE were compared. The rates of fetal loss, preterm birth, small-for-date, low birth weight and preeclampsia were significantly higher in the study groups with a relative risk of 5.6 (95% CI: 2.9-10.9), 3.2 (95% CI: 2.5-4.1), 3.5 (95% CI: 2.4-4.9), 4.2 (95% CI: 3.4-5.3) and 2.9 (95% CI: 1.9-4.4), respectively. The increased rates of most adverse outcomes were still noted even in the cases of uncomplicated SLE. Among women with SLE, lupus nephritis, chronic hypertension, antiphospholipid syndrome, active disease at the onset of pregnancies, and proteinuria were significantly associated with such outcomes. Conclusions Pregnancies with SLE, even in uncomplicated cases with remission, increase the risk of poor pregnancy outcomes. The presence of lupus nephritis, chronic hypertension, antiphospholipid syndrome, active disease at the onset of pregnancies, and proteinuria were significantly associated with such outcomes.

    Since the Austrian propagation bill of July 1, 1992, was passed into law, Austrian physicians are committed to offer psychological counseling to women before performing assisted reproductive techniques, unless refused by the patient. The acceptance of psychotherapeutic counseling (PSITCO) and its influence on pregnancy rate were carefully reviewed. The study comprised 1156 consecutive patients (mean age, 33.3 years) and 1736 in vitro fertilization (IVF) cycles. In a consent form for follicle puncture, the patients were interviewed about PSITCO as follows. Several methods of psychological support during IVF-embryo transfer treatment were offered to patients especially psychotherapy, hypnotherapy, and relaxation and physical perception exercises. Forty-two and three-tenths percent of patients rejected PSITCO, 17.8% had already received PSITCO, and 10.4% were willing to undergo PSITCO. The acceptance of PSITCO had no relevance on pregnancy rate. The cumulative calculation of pregnancy rates showed that up to 56.4% of women who had undergone PSITCO conceived. In patients who were planning to undergo PSITCO, the pregnancy rate was 41.9%. Concerning the cumulative pregnancy rate, this study showed that patients who accepted or underwent PSITCO had a higher pregnancy rate than those who did not avail themselves of this possibility. These results should encourage sterility specialists to consider psychological therapy as an essential aspect of IVF. Solely a written declaration of the patient stating his/her awareness of the possibility to undergo PSITCO is, in our opinion, insufficient.

    Maternal obesity influences a number of metabolic factors that can affect the course of pregnancy. Among these factors, leptin plays an important role in energy metabolism and fetal development during pregnancy. Our objective was to estimate the influence of maternal overweight/obesity on variation in the maternal serum leptin profile during pregnancy. In a prospective cohort of 143 adult gravidas with singleton pregnancies presenting for general prenatal care, we measured serum leptin levels at 6-10, 10-14, 16-20, 22-26, and 32-36 weeks' gestation. The longitudinal effects of maternal prepregnancy BMI, categorized as nonoverweight (≤ 26.0 kg/m(2)) and overweight/obese (>26.0 kg/m(2)), on serum leptin concentration were analyzed using linear mixed models. Overweight/obese women had significantly higher serum leptin concentrations than their nonoverweight counterparts throughout pregnancy (P influence leptin concentrations in overweight/obese women compared to normal-weight women during pregnancy. Such factors may contribute to differences in the intrauterine environment and its influence on pregnancy outcomes in the two groups.

  2. A Case of Live Birth after Uterine Reconstruction for Recurrent Cornual Ectopic Pregnancy following IVF Treatment

    Full Text Available We present a case of recurrent ruptured right cornual ectopic pregnancies conceived after IVF. Following the second episode, a sonohysterography was undertaken to identify possible areas of scar weakness that may rupture with uterine distension in a future pregnancy. The scan revealed asymmetrical muscle thickness in the cornual regions, the right (6 mm being thinner than the left (1.6 cm. Subsequently, an elective laparotomy was undertaken, and the cornua were reconstructed and thickened in several layers by bringing the laterally retracted myometrial fibres onto the reconstruction site. A sono-hysterography after surgery showed satisfactory (3-4 cm myometrial thickness all around. A further cycle of IVF resulted in a singleton pregnancy. Pelvic scans confirmed normal intrauterine pregnancy without any myometrial thinning. She was delivered by an uneventful elective caesarean section at term. We propose that, in those who intend to have further pregnancies after a cornual ectopic pregnancy, a sono-hysterography is possibly the best investigative tool to assess myometrial integrity. This case demonstrates that in women with areas of muscle weakness it is possible to successfully perform an interval elective reconstructive surgery on the uterus that can result in an uneventful pregnancy and birth.

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

    Polyhydramnios is a common complication of fetal malformations and has been described to have high risk of pregnancy complications such as prematurity and placental abruption. In a subgroup of women severe polyhydramnios may lead to maternal dyspnea or untreatable pain, and amnioreduction is the procedure indicated to relieve those symptoms. There is a lack of information concerning the increase in the risk for the pregnancy when the procedure is indicated. Therefore, this study sought to evaluate the risk of complications in pregnancies with severe polyhydramnios that needed amnioreduction in relation to the basal risk for the pregnancy of having polyhydramnios without the need for the procedure. Patients with singleton pregnancies and severe polyhydramnios followed in our fetal medicine center were evaluated retrospectively. Pregnancy complications (prematurity rate, fetal death, premature rupture of membranes, placental abruption and chorioamnionitis) were studied in the group of patients needing the procedure and their risk was compared to the risk of having a pregnancy with severe polyhydramnios but with no need for the procedure. One hundred and thirty-five patients were evaluated. Forty-four patients (32.6%) needed amnioreduction. There was no increase in the risk of having complications when the procedure was needed OR = 1.4 (CI 0.46-1.26). Amnioreduction performed to relieve maternal symptoms did not statistically increase the risk of pregnancy complications with severe polyhydramnios in single pregnancies.

    Animal studies demonstrate that several phthalates are embryofetotoxic and are associated with increased pregnancy loss and malformations. Results from human studies on phthalates and pregnancy loss are inconsistent. We examined pregnancy loss prospectively in relation to urinary phthalate metabolite concentrations among women undergoing medically assisted reproduction. We used data from 256 women conceiving 303 pregnancies recruited between 2004 and 2012 from the Massachusetts General Hospital Fertility Center. We quantified 11 phthalate metabolite concentrations and calculated the molar sum of four di(2-ethylhexyl) phthalate (DEHP) metabolites (ΣDEHP). We estimated risk ratios (RRs) and 95% confidence intervals for biochemical loss and total pregnancy loss (assisted reproduction.

  7. Cornual heterotopic pregnancy: contemporary management options.

    2000-05-01

    This review covers the clinical presentations, treatments, and outcomes of cornual heterotopic pregnancies reported in the literature. Infertile women with a history of ectopic pregnancy, tubal surgery, or disease are at increased risk for cornual heterotopic pregnancy when they undergo in vitro fertilization. Women who have undergone bilateral salpingectomy also seem to be predisposed to this condition when they undergo in vitro fertilization. We recommend that these patients be followed up closely after a successful in vitro fertilization cycle with monitoring of serum beta-human chorionic gonadotropin levels and serial transvaginal ultrasonography because of the high associated morbidity. Laparotomy remains the treatment of choice for rupture of a cornual heterotopic pregnancy. In the absence of cornual rupture, however, medical management is an option that eliminates the risk of surgery and anesthesia and results in outcomes similar to those associated with surgical treatment. Currently there is insufficient evidence to recommend any single treatment modality, and the decision should be based on such factors as clinical presentation, surgeon's expertise, side effects, overall cost, and the patient's preference.

    Women with high levels of physical exercise have an increased demand for oxygen and nutrients. Thus, in pregnancies of women with high levels of exercise, it is conceivable that the supply of oxygen and nutrients to the placenta is suboptimal, and growth could be impaired. The objective was to study the association of frequency of exercise during pregnancy with placental weight and placental to birthweight ratio. This was a prospective study of 80,515 singleton pregnancies in the Norwegian Mother and Child Cohort Study. Frequency of exercise was self-reported by a questionnaire at pregnancy weeks 17 and 30. Information on placental weight and birthweight was obtained by linkage to the Medical Birth Registry of Norway. Placental weight decreased with increasing frequency of exercise (tests for trend, P exercising ≥6 times weekly (difference, 18.8 g; 95% confidence interval, 12.0-25.5). Likewise, in nonexercisers in pregnancy week 30, crude mean placental weight was 684.9 g compared with 661.6 g in women exercising ≥6 times weekly (difference, 23.3 g; 95% confidence interval, 14.9-31.6). The largest difference in crude mean placental weight was seen between nonexercisers at both time points and women exercising ≥6 times weekly at both time points (difference, 31.7 g; 95% confidence interval, 19.2-44.2). Frequency of exercise was not associated with placental to birthweight ratio. We found decreasing placental weight with increasing frequency of exercise in pregnancy. The difference in placental weight between nonexercisers and women with exercising ≥6 times weekly was small and may have no clinical implications. Copyright © 2016 Elsevier Inc.

    2011-05-01

    To describe the characteristics of women who suffer from hyperemesis gravidarum, and explore the independent effect of hyperemesis gravidarum on pregnancy outcome. In The Netherlands Perinatal Registry, we used all data on singleton pregnancies of at least 24 weeks and 500 g without congenital anomalies in the years 2000-2006. We examined the characteristics of women who suffered from hyperemesis gravidarum and their children. Women who suffered from hyperemesis gravidarum were slightly younger; more often primiparous, of lower socio-economic status, of non-Western descent and substance abusers; had more often conceived through assisted reproduction techniques and more often had pre-existing hypertension, diabetes mellitus and psychiatric diseases than women who did not suffer from hyperemesis gravidarum. Also, their pregnancies were more often complicated by hypertension and diabetes and they more often carried a female fetus. Pregnancies complicated by hyperemesis gravidarum significantly more often had an adverse outcome (prematurity or birth weight below the 10th percentile). The increased risk of adverse pregnancy outcomes after hyperemesis gravidarum was largely explained by the differences in maternal characteristics (crude OR 1.22 (95% CI 1.10-1.36), adjusted OR was 1.07 (95% CI 0.95-1.19)). Hyperemesis gravidarum is associated with adverse pregnancy outcomes. This is largely explained by differences in maternal characteristics. Given the impact of the early environment on later health (which is independent of size at birth), studies that aim to assess the long-term consequences of hyperemesis gravidarum need to be given high priority.

    Polyhydramnios is present in approximately 2% of pregnancies and it has been associated with a variety of adverse pregnancy outcomes. The aim of our study was to evaluate the association between polyhydramnios and adverse pregnancy outcomes. This was a retrospective case control study of 288 singleton pregnancies delivered in the Rotunda Hospital, Dublin, between 2013 and 2014. Polyhydramnios was defined as: (i) amniotic fluid index (AFI) ≥ 25 cm; (ii) maximal vertical pocket (MVP) of ≥8 cm; and (iii) a gestational age-specific threshold for AFI. Demographic information, obstetric and neonatal outcomes were obtained by review of hospital databases. Exclusion criteria included gestational or pre-existing diabetes, multiple pregnancy, carrying a fetus with structural or chromosomal abnormalities, Rhesus factor isoimmunisation, and TORCH screen positive. Outcomes were compared with outcomes of those without polyhydramnios. A total of 8798 deliveries occurred during the study period. The frequency of polyhydramnios was 1.6%. One hundred and forty-four women were selected in each group. There was no significant difference in preterm deliveries, low birth weight, low Apgar score at one minute and five minutes and perinatal mortality. However, increase in caesarean delivery rate (43.1% vs 21.5%), number of fetal distresses (17.4% vs 6.9%) and number of neonatal intensive care unit (NICU) admissions (17.4% vs 4.9%) were observed in our study. In conclusion, idiopathic polyhydramnios is associated with specific adverse outcomes, such as higher rate of caesarean delivery, fetal distress and NICU admissions. Therefore, close surveillance of these pregnancies is required, especially near term. © 2017 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

    Pregnancy is a special physical period in reproductive age women, which has a beneficial influence on the course of certain autoimmune diseases. It has been recently suggested that the microbiome undergoes profound changes during pregnancy that are associated with host physiological and immunological adaptations. The maternal microbiome remodeling during pregnancy is an active response of the mother, possibly to alter immune system status and to facilitate metabolic and immunological adaptations, which are needed for a successful pregnancy. In this review, we attempt to discuss (i) the role of maternal microbiome in pregnancy outcomes known to adversely influence neonatal and infant health, including preterm birth, cardiometabolic complications of pregnancy, and gestational weight gain; (ii) the association of microbiome with autoimmunity, allergy diseases, and asthma during pregnancy; and (iii) the impact of helminth infection during pregnancy. © 2017 John Wiley & Sons A/S.

    Full Text Available Throughout pregnancy, the body undergoes a variety of physiologic changes. The cutaneous findings can be most noticeable and often worrisome to both physicians and patients. Obstetricians and dermatologists must be able to differentiate between changes that are benign and those that may be pathologic. Most physicians recognize benign changes that are commonly described in literature such as hyperpigmentation, melasma, striae gravidarum, and telogen effluvium; however, they may be unaware of changes that tend to be less frequently discussed. This comprehensive review provides a broad overview of the physiologic cutaneous changes that occur during pregnancy as described in the literature over the past 10 years.

    CONTEXT Adolescents’ desire for a pregnancy has been explored more among females than among males. A more comprehensive understanding of teenagers’ pregnancy desires is needed to inform pregnancy prevention efforts and to support couples as they undergo the transition to parenthood. METHODS In an observational cohort study conducted in 2007–2011 at clinics in Connecticut, data were collected from 296 couples (females aged 14–21 and their partners) who were expecting a baby. The degree to which each partner had wanted the pregnancy and partners’ perceptions of each other’s pregnancy desires were assessed. Multilevel regression models examined associations between pregnancy desire and individual, partner, family and community characteristics, and between desire and life and relationship satisfaction. RESULTS Forty-nine percent of females and 53% of males reported having wanted the pregnancy. Pregnancy desire scores were positively associated with being male, expecting a first baby, perceived partner desire and parental response to the pregnancy; scores were negatively associated with being in school, being employed and parental support. Females’ perceptions of their partners’ pregnancy desires were slightly more accurate than males’ (kappas, 0.36 and 0.28, respectively). Pregnancy desire was positively associated with both life and relationship satisfaction, particularly among males. CONCLUSIONS Adolescents’ pregnancy desires require further attention as a possible focus of pregnancy prevention efforts, and health care providers may want to ensure that young couples with unwanted pregnancies are offered additional psychological and social services as they transition to parenthood.

    International Nuclear Information System (INIS)

    2008-01-01

    Omental pregnancy is a rare form of ectopic pregnancy and can be seen primarily or secondary to a tubal pregnancy. A 25-yeal-old woman presented with abdominal distention with pain and anemia without vaginal bleeding. After a provisional diagnosis of ruptured ectopic pregnancy, laparotomy was performed. On surgical exploration, the bilateral tubes and ovaries were intact, however, an omental pregnancy was detected as the cause of hemoperitoneum. Partial omentectomy was performed. Although most cases are secondary, presented here is an additional case of primary omental pregnancy at 12 weeks according to Studdiford's criteria. Histological evidence of neovascularization into the supporting tissue confirmed our diagnosis. A primary omental pregnancy should always be considered as a possible explanation for severe hemoperitoneum in ectopic pregnancies presenting with acute abdomen and with intact adnexes on surgical exploration.

    Many physiological and anatomical changes of pregnancy affect the respiratory system. These changes often affect the presentation and management of the various respiratory illnesses in pregnancy. This article focuses on several important respiratory issues in pregnancy. The management of asthma, one of the most common chronic illnesses in pregnancy, remains largely unchanged compared to the nonpregnant state. Infectious respiratory illness, including pneumonia and tuberculosis, are similarly managed in pregnancy with antibiotics, although special attention may be needed for antibiotic choices with more pregnancy safety data. When mechanical ventilation is necessary, consideration should be given to the maternal hemodynamics of pregnancy and fetal oxygenation. Maintaining maternal oxygen saturation above 95% is recommended to sustain optimal fetal oxygenation. Cigarette smoking has known risks in pregnancy, and current practice guidelines recommend offering cognitive and pharmacologic interventions to pregnant women to assist in smoking cessation.

  7. Pregnancy and cardiovascular risk for women with Turner syndrome.

    Science.gov (United States)

    Bondy, Carolyn

    2014-07-01

    Most women with Turner syndrome (TS) are infertile due to primary ovarian failure. However, approximately 5% experience spontaneous pregnancy, and recently, more women with TS have used assisted reproductive technology with donated oocytes (ART-OD) to become pregnant. The first generation of Turner patients undergoing ART-OD demonstrated a high rate of fatal aortic dissection in late pregnancy or postpartum. More recent observations, particularly from Nordic countries, suggest a lesser risk of dissection, but confirm a high rate of pre-eclampsia in ART-OD pregnancies. This article reviews publications since 2000 concerning maternal outcomes for pregnancies in women with TS to determine if specific risk factors such as type of pregnancy, age, or presence of underlying congenital cardiovascular disease may identify women at special risk.

The relative risk for an imprinting phenotype such as Silver-Russell syndrome, Beckwith-Wiedemann syndrome, or Angelman syndrome is increased in the assisted reproduction population, but the actual risk for one of these phenotypes to occur in an assisted pregnancy is estimated to be low, at less than 1 in 5000.

    Preterm premature rupture of the membranes (PPROM) remains the leading cause of preterm deliveries and neonatal mortality and morbidity. The current cohort study sought to retrospectively examine perinatal outcomes in cases of PPROM < 34 weeks' gestation that were managed conservatively from 2010 to 2012 and to identify risk factors for short-term neonatal outcomes. Subjects were 510 pregnancies consisting of 114 twin and 396 singleton pregnancies. Clinical chorioamnionitis occurred in 17.8% of the pregnancies. Neonatal mortality was 7.4%, the rate of major neonatal conditions was 40%, and the rate of NICU admission was 72.9%. The latency period exceeded 48 h in 62.5% of the pregnancies and 7 days in 24.3% of the pregnancies. Twin pregnancies had a shorter latency period than singleton pregnancies (median of 2 days versus 4 days, p < 0.001). Pregnancies complicated with early vaginal bleeding had a higher neonatal mortality (13.95% vs. 6.36%, p = 0.013) and morbidity (51.16% vs. 38.32%, p = 0.024), fewer weeks of gestation at PPROM (p = 0.029). Multivariate logistic regression analysis revealed that weeks of gestation at PPROM (OR: 0.953, 95% CI: 0.939-0.966, p < 0.001) and a latency period (OR: 0.948, 95%CI: 0.926-0.970, p < 0.001) were associated with neonatal mortality or morbidity. A twin pregnancy (OR: 0.319, 95% CI: 0.17-0.6, p < 0.001) and weeks of gestation at PPROM (OR: 0.737, 95% CI: 0.66-0.822, p < 0.001) were associated with the latency period. Gestational age at PPROM, a twin pregnancy, and the latency period are associated with neonatal mortality and morbidity.

    At our medical center, female patients who have undergone bariatric surgery are advised to defer pregnancy for 2 years after surgery to avoid the following complications and their potential consequences for the fetus: inadequate gestational weight gain, inadequate postsurgical weight loss, hyperemesis gravidarum, nutritional deficiencies, gestational diabetes, and gestational hypertension. To examine the effect of time from surgery to conception on pregnancy course and outcomes in bariatric patients. University. We identified 73 pregnancies in 54 women who became pregnant after undergoing bariatric surgery. Surgery to conception interval was compared between pregnancies that were carried to delivery and 8 pregnancies that resulted in spontaneous abortion. Of 41 pregnancies that were carried to delivery, 26 occurred in women who had undergone surgery less than 2 years before conception, and 15 occurred in women who had undergone surgery greater than 2 years before conception. Gestational age at delivery, number of neonatal intensive care unit admissions, gestational weight gain, hyperemesis gravidarum, nutritional deficiencies, gestational diabetes, and gestational hypertension during pregnancy were compared for the 2 groups. Eight patients who had spontaneous abortion had a significantly shorter time from surgery to conception. There were no significant differences between our 2 groups in rates of preterm deliveries, neonatal intensive care unit admission, gestational weight gain, hyperemesis, nutritional deficiencies, gestational diabetes, or gestational hypertension. Becoming pregnant within the first 2 years after bariatric surgery appears to have no effect on pregnancy course and outcomes. Women who miscarried had a significantly lower mean surgery to conception interval. These results fail to show an increased rate of pregnancy complications during the first 2 years after bariatric surgery. Copyright © 2017 American Society for Bariatric Surgery. Published by

    It is evident that the incidence of teenage pregnancy has been increasing in the past decades and consequently poses significant problems on maternal and child health. The present study was aimed to compare obstetric and neonatal outcomes between teenage and non-teenage pregnancy. A retrospective cohort study was conducted to investigate 957 singleton pregnant women attending labor rooms in Naresuan University Hospital between October 2006 and September 2013 by comparing the pregnancy outcomes of 268 teenage pregnancy (woman age less than 20 years at the first time of antenatal care visit) with 689 non-teenage pregnancy (woman age 20 to 34 years). The obstetrics and neonatal complication was the main outcome of interest. The incidence of teenage pregnancy was 15.24% during seven years of study. As opposed to non-teenage mothers, complete attending antenatal care visit was less likely to be found among teenage mothers, 66.5% vs. 90.5% respectively (p teenage mothers (59.7% vs. 36.4%). The occurrence of cephalo-pelvic disproportion (CPD) seemed to be lower in teenage group as compared to non-teenage group, 14.5% vs. 26.4% (p teenage group, 3.8% vs. 8.4% (p = 0.016). The proportion of preterm birth was found to be higher in teenage pregnancy compared to non-teenage pregnancy (16.2% vs. 5.5%, p teenage pregnancy, 7.1% vs. 3.1% (p = 0.01). Even though obstetric complications were less likely to occur among teenage pregnancies, most of the neonatal untoward consequences were observed in mothers with younger ages. The finding suggests the need of appropriate health care services for teenage mothers as to monitor harmful complications to both mother and her child.

  8. Physiologic and Pharmacokinetic Changes in Pregnancy

    Directory of Open Access Journals (Sweden)

    Maged eCostantine

    2014-04-01

    Full Text Available Physiologic changes in pregnancy induce profound alterations to the pharmacokinetic properties of many medications. These changes affect distribution, absorption, metabolism, and excretion of drugs, and thus may impact their pharmacodynamic properties during pregnancy. Pregnant women undergo several adaptations in many organ systems. Some adaptations are secondary to hormonal changes in pregnancy, while others occur to support the gravid woman and her developing fetus. Some of the changes in maternal physiology during pregnancy include, for example, increased maternal fat and total body water, decreased plasma protein concentrations, especially albumin, increased maternal blood volume, cardiac output and blood flow to the kidneys and uteroplacental unit, and decreased blood pressure. The maternal blood volume expansion occurs at a larger proportion than the increase in red blood cell mass, which results in physiologic anemia and hemodilution. Other physiologic changes include increased tidal volume, partially compensated respiratory alkalosis, delayed gastric emptying and gastrointestinal motility, and altered activity of hepatic drug metabolizing enzymes. Understating these changes and their profound impact on the pharmacokinetic properties of drugs in pregnancy is essential to optimize maternal and fetal health.

    To estimate whether women who receive an immediate postabortion etonogestrel subdermal implant have higher discontinuation rates than women who undergo an interval insertion (insertion not associated with a recent pregnancy). This was a secondary analysis of the Contraceptive CHOICE Project. We compared 12-month continuation rates for the subdermal implant between women undergoing immediate postabortion placement and women who underwent an interval placement. Continuation rates were compared using Kaplan-Meier estimator of survival function and Cox proportional hazard models. Over the study period, 141 women received the implant immediately postabortion and 935 women underwent an interval placement. The 12-month continuation rates were similar: 81.5% among women undergoing immediate postabortion placement and 82.8% among women undergoing interval placement (P=.54). In the survival analysis, women who received an immediate postabortion implant were no more likely to discontinue their method than women who had an interval placement (adjusted hazard ratio 1.04, 95% confidence interval 0.68-1.60). The most common reason given for discontinuation was frequent or irregular bleeding, which was reported by 65.4% of women discontinuing in the immediate postabortion group and 56.7% in the interval group. Women who undergo immediate postabortion placement of the subdermal implant have high rates of continuation that are equivalent to women undergoing interval insertion. Immediate postabortion long-acting reversible contraceptives should be available to women undergoing induced abortion to decrease the risk of repeat unplanned pregnancy. II.

    Full Text Available Juvenile dermatomyositis has variable clinical presentations both in and outside of pregnancy. A literature review indicated that optimal maternal and fetal outcomes can be anticipated when the pregnancy is undertaken while the disease is in remission. Poorer outcomes are associated with flare-up of the disease in early pregnancy compared with exacerbation in the second or third trimester, when fetal prognosis is usually good. We present a case of JDM in pregnancy with disease exacerbation late in pregnancy and review of the relevant literature.

    QUESTION: A 26-year-old patient in our clinic, who was 18 weeks pregnant at the time, experienced acute abdominal pain and was diagnosed with appendicitis. The inflamed appendix was successfully removed. Is her pregnancy at risk? ANSWER: Appendicitis is not rare during pregnancy and is associated with increased reproductive risk. Women who have undergone appendectomy during pregnancy are at higher risk of fetal loss, especially in early pregnancy and with appendiceal perforation, and of premature contractions and labour. Despite the difficulty of diagnosing appendicitis during pregnancy, appendectomy should not be delayed. PMID:15318670

    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.

    Full Text Available We present two cases of carnitine deficiency in pregnancy. In our first case, systematic screening revealed L-carnitine deficiency in the first born of an asymptomatic mother. In the course of her second pregnancy, maternal carnitine levels showed a deficiency as well. In a second case, a mother known with carnitine deficiency under supplementation was followed throughout her pregnancy. Both pregnancies had an uneventful outcome. Because carnitine deficiency can have serious complications, supplementation with carnitine is advised. This supplementation should be continued throughout pregnancy according to plasma concentrations.

    To evaluate the association between first-trimester inter- and intrafetal size discrepancies and pregnancy outcome, among bichorionic-biamniotic twins conceived by IVF. A retrospective study design was used. Tertiary university-affiliated medical center. All women with a viable first-trimester bichorionic-biamniotic twin gestation, who conceived after IVF in 2007-2015. None. The association between fetal size differences and pregnancy outcome was analyzed. Intrafetal size discordance was defined as a difference between the actual gestational age calculated by ovum pickup (OPU) date and the evaluated gestational age by crown-rump length (CRL), for each twin. Intertwin size discrepancy was defined as a difference in CRL between the twins. The primary outcome was the number of live-born fetuses; the secondary outcome measures were gestational age at birth, birth weight percentile, and birth weight discordancy. A total of 277 women met the study criteria and were divided into three groups by outcome: 218 (78.7%) live-born twins, 41 (14.8%) live-born singleton, and 19 (6.5%) non-live-born pregnancy. Among the smaller than expected twin, the association of CRL-OPU differences with the primary outcome was significant for twin live-born delivery (-1.43 day), singleton live-born delivery (-4.12 days), and non-live-born pregnancy (-6.72 days). For the relatively larger twin, the association was significant for non-live-born pregnancy (-4.33 days) compared with any live-born delivery, either singleton (-0.95 days) or twin (-0.21 days). Among IVF conceived twin gestations, a CRL-OPU gap was associated with an increased risk of a negative pregnancy outcome. Copyright © 2017 American Society for Reproductive Medicine.

    A 200-patient cohort has been established so that longitudinal analysis can determine the likelihood of an individual in vitro fertilization (IVF) entrant achieving a viable uterine pregnancy or a live baby. After a minimum of 39 months of access to repeated treatment cycles, 24% have achieved at least one viable pregnancy by undergoing an average of 2.48 treatment cycles per cohort member. Life-table analysis shows that most of these pregnancies have occurred in the first year after entering the program. Many members have undergone only one or two treatment cycles. In the future, greater emphasis will need to be placed on factors which encourage couples to undergo additional cycles of treatment. This, as much as technical advances, may increase outcome figures.

    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 (obstetrical outcomes compared with ICSI pregnancies. Hence, blastomere biopsy for PGD does not seem to increase the risk for adverse perinatal outcome compared with ICSI pregnancies. Copyright © 2017 Reproductive Healthcare Ltd.

    Ectopic pregnancy is an important cause of maternal morbidity and mortality. Women who experience fragmented care may undergo unnecessary delays to diagnosis and treatment. Based on ectopic pregnancy cases observed in clinical practice that raised our concern about fragmentation of care, we designed an exploratory study to describe the number, characteristics, and outcomes of fragmented care among patients with ectopic pregnancy at one urban academic hospital. Chart review with descriptive statistics. Fragmented care was defined as a patient being evaluated at an outside facility for possible ectopic pregnancy and transferred, referred, or discharged before receiving care at the study institution. Of 191 women seen for possible or definite ectopic pregnancy during the study period, 42 (22 %) met the study definition of fragmented care. The study was under-powered to observe statistically significant differences across groups, but we found concerning, non-significant trends: patients with fragmented care were more likely to be Medicaid recipients (65.9 vs. 58.8 %) and to experience a complication (23.8 vs. 18.1 %) compared to those with non-fragmented care. Most patients (n = 37) received no identifiable treatment prior to transfer and arrived to the study hospital with no communication to the receiving hospital from the outside provider (n = 34). Nine patients (21 %) presented with ruptured ectopic pregnancies. The fragmentation we observed in our study may contribute to previously identified socio-economic disparities in ectopic pregnancy outcomes. If future research confirms these findings, health information exchanges and regional coordination of care may be important strategies for reducing maternal mortality.

    Ovarian endometriomas are classified as benign ovarian lesions. During pregnancy endometriomas may undergo major morphological changes which are referred to as 'decidualisation'. Decidualised ovarian endometrioma may resemble malignant ovarian tumours on ultrasound examination. The aim was to study variations in the morphology and size of ovarian endometriomas diagnosed on ultrasound during pregnancy. We searched our database to identify pregnant women who were diagnosed with ovarian endometriomas on ultrasound in order to study the effect of pregnancy on their morphological characteristics. In women who underwent serial scans during pregnancy we examined the changes in the size of endometriomas with advancing gestation. Twenty four patients with a total of 34 endometriomas were included in the analysis. All women were managed expectantly during pregnancy. On the first ultrasound scan 29/34 (85.3%, 95% CI 73.4 - 97.2) endometriomas appeared unilocular with fine internal echoes ('ground glass' contents) and they were poorly vascularised on Doppler examination. 1/34 (2.9% 95% CI 0.0 - 8.5) endometrioma was multilocular, with regular margins, 'ground glass' contents and it was also poorly vascularised. 4/34 (11.8%, 95% CI 1.0 - 22.6) had sonographic features suggestive of decidualisation such as thick and irregular inner wall, papillary projections and highly vascular on Doppler examination. The endometriomas showed a tendency to decrease in size during pregnancy. Pregnancy has a major effect on the size and morphological appearances of ovarian endometriomas. Rapid regression of decidualised endometriomas is a helpful feature which could be used to confirm their benign nature.

    Abdominal pregnancy is a rare entity, which has been classified as primary or secondary by Studiford criteria. A retrospective study, between January 1989 and December 1994, realized at Instituto Nacional de Perinatología, found 35,080 pregnancies, from which 149 happened to be ectopic, and 6 of them were abdominal. All patients belonged to a low income society class, age between 24 and 35 years, and average of gestations in 2.6. Gestational age varied from 15 weeks to 32.2 weeks having only one delivery at term with satisfactory postnatal evolution. One patient had a recurrent abdominal pregnancy, with genital Tb as a conditional factor. Time of hospitalization varied from 4 to 5 days, and no further patient complications were reported. Fetal loss was estimated in 83.4%. Abdominal pregnancy is often the sequence of a tubarian ectopic pregnancy an when present, it has a very high maternal mortality reported in world literature, not found in this study. The stated frequency of abdominal pregnancy is from 1 of each 3372, up to 1 in every 10,200 deliveries, reporting in the study 1 abdominal pregnancy in 5846 deliveries. The study had two characteristic entities one, the recurrence and two, the delivery at term of one newborn. Abdominal pregnancy accounts for 4% of all ectopic pregnancies. Clinical findings in abdominal pregnancies are pain, transvaginal bleeding and amenorrea, being the cardinal signs of ectopic pregnancy.

    Recent research has put the spotlight on two different aspects of pregnancy after bariatric surgery: safety of the mother and fetus, and the procedure's effectiveness in preventing the complications surrounding reproduction and pregnancy often seen in the obese woman. To evaluate the pregnancy outcome foLlowing bariatric surgery. Although there are severaL reports documenting poor perinatal outcomes and late surgical complications during pregnancies subsequent to bariatric surgery, systematic studies have generaLLy not proven such an association. Pregnancy after bariatric surgery appears to be safe, and in general perinatal outcome is better when compared to pregnancies of obese women. Providers should be familiar with potential complications related to postoperative pregnancies and be prepared to provide appropriate interventions such as nutritional supplementation and band adjustment when necessary.
