Women who discover they are pregnant after exposure to a drug and pregnant women who have a condition that requires continued treatment during pregnancy are told to balance the benefits and risks of the exposure to justify continuation of treatment, discontinuation of treatment or, possibly, pregnancy termination. However, there are limited data available to inform decision-making. The Merck Pregnancy Registry Program is a company-run pregnancy registry whose objective is to acquire and analyse information on drug exposures and pregnancy outcomes to better describe the safety profile of Merck products used during pregnancy. Information is collected from women and healthcare providers who call to report drug exposure during pregnancy. Prospective pregnancies are followed up to outcome and data are collected via questionnaires, telephone calls and a review of medical records. Reports are classified as prospective (information received prior to knowledge of pregnancy outcome) or retrospective (received after the outcome is known). Congenital anomaly reports are assessed for timing of exposure, maternal age and medical history, biological plausibility and concomitant medication exposures. Rates of pregnancy outcomes and birth defects in the prospective cohort are computed and confidence intervals are calculated to reflect the strength of the finding based on the sample size. Rates of pregnancy outcomes in the Pregnancy Registry are compared with the rates of pregnancy outcomes in the general US population and, if available, in subpopulations with the relevant disease states. The limitations of post-marketing surveillance are well known as voluntary reporting of individuals and healthcare professionals is known to be subject to various types of bias. Small sample size is another major limitation. However, the strength of the registry lies in its ability to gather pregnancy outcome reports early in the life of a product and to recognise and analyse unusual birth defects

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

2010-01-01

Background Time-to-pregnancy (TTP) has never been studied in an African setting and there are no data on the rates of adverse pregnancy outcomes in South Africa. The study objectives were to measure TTP and the rates of adverse pregnancy outcomes in South Africa, and to determine the reliability of the questionnaire tool. Methods The study was cross-sectional and applied systematic stratified sampling to obtain a representative sample of reproductive age women for a South African population. Data on socio-demographic, work, health and reproductive variables were collected on 1121 women using a standardized questionnaire. A small number (n = 73) of randomly selected questionnaires was repeated to determine reliability of the questionnaire. Data was described using simple summary statistics while Kappa and intra-class correlation statistics were calculated for reliability. Results Of the 1121 women, 47 (4.2%) had never been pregnant. Mean gravidity was 2.3 while mean parity was 2.0 There were a total of 2467 pregnancies; most (87%) resulted in live births, 9.5% in spontaneous abortion and 2.2% in still births. The proportion of planned pregnancies was 39% and the median TTP was 6 months. The reliability of the questionnaire for TTP data was good; 63% for all participants and 97% when censored at 14 months. Overall reliability of reporting adverse pregnancy outcomes was very high, ranging from 90 - 98% for most outcomes. Conclusion This is the first comprehensive population-based reproductive health study in South Africa, to describe the biologic fertility of the population, and provides rates for planned pregnancies and adverse pregnancy outcomes. The reliability of the study questionnaire was substantial, with most outcomes within 70 - 100% reliability index. The study provides important public information for health practitioners and researchers in reproductive health. It also highlights the need for public health intervention programmes and epidemiological

Introduction Pregnancy anxiety is an important psychosocial risk factor that may be more strongly associated with adverse birth outcomes than other measures of stress. Better understanding of the upstream predictors and causes of pregnancy anxiety could help to identify high-risk women for adverse maternal and infant outcomes. The objective of the present study was to measure the associations between five past pregnancy outcomes (live preterm birth (PTB), live term birth, miscarriage at <20 weeks, stillbirth at ≥20 weeks, and elective abortion) and pregnancy anxiety at three trimesters in a subsequent pregnancy. Methods Analyses were conducted using data from the 3D Cohort Study, a Canadian birth cohort. Data on maternal demographic characteristics and pregnancy history for each known previous pregnancy were collected via interviewer-administered questionnaires at study entry. Pregnancy anxiety for the index study pregnancy was measured prospectively by self-administered questionnaire following three prenatal study visits. Results Of 2366 participants in the 3D Study, 1505 had at least one previous pregnancy. In linear regression analyses with adjustment for confounding variables, prior live term birth was associated with lower pregnancy anxiety in all three trimesters, whereas prior miscarriage was significantly associated with higher pregnancy anxiety in the first trimester. Prior stillbirth was associated with greater pregnancy anxiety in the third trimester. Prior elective abortion was significantly associated with higher pregnancy anxiety scores in the first and second trimesters, with an association of similar magnitude observed in the third trimester. Discussion Our findings suggest that the outcomes of previous pregnancies should be incorporated, along with demographic and psychosocial characteristics, into conceptual models framing pregnancy anxiety.

The aim of this study was to report outcome of subsequent pregnancy after early-onset preeclampsia in first pregnancy, and to evaluate potential risk factors for recurrence of preeclampsia and preterm delivery. Reproductive follow-up data were obtained for women with a history of early-onset preeclampsia, resulting in delivery before 34 weeks of gestation at the University Medical Center Utrecht, The Netherlands, between July 1993 and September 2002. The relative contributions of demographic data, outcome variables of first pregnancy, and common thrombophilias to the recurrence risk of preeclampsia and preterm delivery in subsequent pregnancy, were estimated by Cox proportional hazard models. Subsequent pregnancy outcome data were available for 120 women. Overall, preeclampsia reoccurred in the second pregnancy in 30 women (25%). However, 6 women delivered before 34 weeks of gestation (5%), 20 women between 34 and 37 weeks of gestation (17%), and 94 women after 37 weeks of gestation (78%). Forty-one women (34%) had an uneventful pregnancy. Recurrence rates for preeclampsia or preterm delivery were not related to severity of first pregnancy complications, including delivery before 28 weeks of gestation, occurrence of hemolysis, elevated liver enzymes, and low platelet count syndrome, small-for-gestational age infants, and to hereditary or acquired thrombophilias. Chronic hypertension was related to a higher recurrence risk of preeclampsia in the second pregnancy (hazard ratio 2.1, 95% CI 1.0-4.4), and smoking was related to a higher recurrence risk of preterm birth (hazard ratio 2.4, 95% CI 1.1-5.6). Outcomes of subsequent pregnancy after first pregnancy with early-onset preeclampsia is generally favorable.

To analyze the maternal and obstetric outcomes of patients with Alport syndrome. We describe the pregnancy course of 8 pregnancies of three family members with the autosomal dominant (the rarest) form of Alport syndrome. We also analyzed 10 previously reported pregnancies with other Alport mutations in order to explore risk factors for unfavorable obstetric outcomes and maternal renal deterioration. In 13 pregnancies (72 %), renal function did not deteriorate permanently. All of these women had pre-pregnancy mild chronic kidney disease (CKD stage G1). In all of them, only a transient increase in proteinuria was recorded and in one case there was a transient decrease in the estimated glomerular filtration rate. In four other pregnancies (22 %), renal function deteriorated following pregnancy. All of them were complicated with pre-eclampsia. One woman had pre-pregnancy CKD-G2A3 and chronic hypertension. Two women had CKD-G1A3 of whom one had pre-pregnancy proteinuria near the nephrotic range. In the fourth case, renal function deterioration was reported without information on the exact pre-pregnancy renal function. In the last case, CKD-G2 was reported after pregnancy without information on CKD stage prior to pregnancy. Severe proteinuria did not imply a permanent renal function deterioration if it developed during pregnancy. Ten pregnancies ended with preterm birth (56 %). Two stillbirths were reported (11 %); however, only one was attributed to maternal health deterioration. Data regarding pregnancy outcomes in Alport syndrome is limited. The outcome seems favorable when pre-pregnancy kidney function is normal or near normal and when chronic hypertension/pre-eclampsia is absent.

Appropriate counseling and treatment for women with multiple sclerosis (MS) who may become pregnant requires an understanding of the effects of exposure to disease-modifying therapies (DMTs) during pregnancy. Current reports and studies are limited in their usefulness, mostly by small sample size. Branded glatiramer acetate (GA) is a DMT approved for the treatment of relapsing forms of MS. For more than 2 decades, it has been shown to be efficacious and to have a favorable safety profile. The Teva Pharmaceutical Industries Ltd global pharmacovigilance database comprises data from more than 7000 pregnancies, during which women with MS were exposed to treatment with branded GA. We analyzed data from Teva's global pharmacovigilance database. Pregnancy outcomes for patients treated with branded GA were compared with reference rates of abnormal pregnancy outcomes reported in two large registries representing the general population. Pregnancies exposed to branded GA were not at higher risk for congenital anomalies than what is expected in the general population. These data provide evidence that branded GA exposure during pregnancy seems safe, without teratogenic effect.

Pregnant women and their developing fetuses are vulnerable to multiple environmental insults, including exposure to aflatoxin, a mycotoxin that may contaminate as much as 25% of the world food supply. We reviewed and integrated findings from studies of aflatoxin exposure during pregnancy and evaluated potential links to adverse pregnancy outcomes. We identified 27 studies (10 human cross-sectional studies and 17 animal studies) assessing the relationship between aflatoxin exposure and adverse birth outcomes or anemia. Findings suggest that aflatoxin exposure during pregnancy may impair fetal growth. Only one human study investigated aflatoxin exposure and prematurity, and no studies investigated its relationship with pregnancy loss, but animal studies suggest aflatoxin exposure may increase risk for prematurity and pregnancy loss. The fetus could be affected by maternal aflatoxin exposure through direct toxicity as well as indirect toxicity, via maternal systemic inflammation, impaired placental growth, or elevation of placental cytokines. The cytotoxic and systemic effects of aflatoxin could plausibly mediate maternal anemia, intrauterine growth restriction, fetal loss, and preterm birth. Given the widespread exposure to this toxin in developing countries, longitudinal studies in pregnant women are needed to provide stronger evidence for the role of aflatoxin in adverse pregnancy outcomes, and to explore biological mechanisms. Potential pathways for intervention to reduce aflatoxin exposure are urgently needed, and this might reduce the global burden of stillbirth, preterm birth, and low birthweight. PMID:28500823

Pregnancy outcomes in women with spinal muscular atrophy: A review.

PubMed

Abati, Elena; Corti, Stefania

2018-05-15

Spinal muscular atrophy (SMA) is an autosomal recessive disease characterized by muscle weakness and atrophy resulting from progressive degeneration and loss of the anterior horn cells in the spinal cord and brain stem nuclei. The onset of weakness ranges from prenatal age to young adulthood. Thus, many female patients reach fertile age and may consider getting pregnant. However, only little information is available about outcomes and complications of pregnancy in women with SMA. In this review, we compared different studies on the subject, then we analyzed outcomes in the different stages of the pregnancy (preconceptional period, embryonal period, fetal period, delivery and post partum), with a special focus on maternal and fetal complications, prematurity, mode of delivery, anesthesiological risk, respiratory function and influence of pregnancy on the disease course. This is the first review focused exclusively on pregnancy in women affected by SMA. Our aim is to help clinicians who wish to understand the risks connected with pregnancy in SMA patients and to manage pregnancy course and delivery in an evidence-based and patient-oriented manner.

We examined the effects of home-based walking on sedentary Japanese women's pregnancy outcomes and mood. A randomized controlled trial was conducted, involving 118 women aged 22-36 years. Participants were randomly assigned to walking intervention (n = 60) or control (n = 58) groups. The walking group was instructed to walk briskly for 30 min, three times weekly from 30 weeks' gestation until delivery. Both groups counted their daily steps using pedometers. Pregnancy and delivery outcomes were assessed, participants completed the Profile of Mood States, and we used the intention-to-treat principle. Groups showed no differences regarding pregnancy or delivery outcomes. The walking group exhibited decreased scores on the depression-dejection and confusion subscales of the Profile of Mood States. Five of the 54 women in the intervention group who remained in the study (9.2%) completed 100% of the prescribed walking program; 32 (59.3%) women completed 80% or more. Unsupervised walking improves sedentary pregnant women's mood, indicating that regular walking during pregnancy should be promoted in this group. © 2016 John Wiley & Sons Australia, Ltd.

Aims To examine the relationship between personality, pregnancy and birth outcomes in adolescents Background Personality has been shown to be a strong predictor of many health outcomes. Adolescents who become pregnant have worse birth outcomes than adults. Design Cross-sectional study using data from the National Longitudinal Study of Adolescent Health (baseline, 1994-1995; follow-up, 2007-2008). Methods The study sample was 6529 girls, 820 of whom reported on pregnancy outcomes for a teenage birth. Personality data was taken from the Mini International Personality Item Pool personality tool, which measures the five-factor personality traits of neuroticism, conscientiousness, intellect/imagination, extraversion and agreeableness. Logistic regression was used to predict teen pregnancy and linear regression was used to predict birth weight and gestational age with adjustment for confounders and stratification by race. Results Agreeableness and intellect/imagination were associated with a reduced likelihood of becoming pregnant as an adolescent, while neuroticism, conscientiousness and extraversion were all associated with an increased likelihood of becoming pregnant. Higher neuroticism was associated with lower birth weight and gestational age among Black girls, but not non-Black. Conscientiousness was associated with lower gestational age among non-Black girls. No relationships were found with extraversion or agreeableness and birth outcomes. Receiving late or no prenatal care was associated with higher intellect/imagination. Conclusions Personality is understudied with respect to pregnancy and birth outcomes compared with other health outcomes. Such research could help professionals and clinicians design and target programs that best fit the characteristics of the population most likely to need them, such as those with high neuroticism.

Pregnancy complications elevate risk of associated adverse medical, socioenvironmental, and behavioral outcomes in children. These are likely to have a substantial impact on neuropsychological functioning and mental health across the child's lifespan. Thus, an understanding of the complex relationships between pregnancy complications and neuropsychological outcomes is critical for both practitioners and researchers. This review summarizes prevalent pregnancy complications and the associated psychological and neuropsychological findings, highlighting methodological challenges that have restricted investigations of these outcomes and identifying opportune areas for future study.

Pregnancy Outcomes Related to Mycophenolate Exposure in Female Kidney Transplant Recipients.

In 2012, the U.S. Food and Drug Administration issued guidelines advising kidney transplant recipients (KTRs) to discontinue mycophenolate (MPA) in preparation for pregnancy. Little is known about how this guidance has affected pregnancy and graft outcomes. The purpose of this retrospective cohort study was to investigate any association between the discontinuation of MPA and KTR pregnancy and graft outcomes. Data from the National Transplantation Pregnancy Registry included 382 cases in which KTRs managed on MPA became pregnant. Overall, 22 variables, including the time in which a KTR discontinued MPA, were assessed across four end points: miscarriages, birth defects, and 2- and 5-year postpartum graft loss. Birth defects and miscarriages were similar among KTRs who discontinued MPA >6 and <6 weeks prior to pregnancy and during the first trimester. In contrast, discontinuing MPA during the second trimester or later significantly increased the risk of miscarriages (odds ratio [OR] 9.35, 95% confidence interval [CI] 4.31-20.00, p < 0.001) and birth defects (OR 6.06, 95% CI 1.96-18.87, p = 0.002). Discontinuing MPA <6 weeks prior to pregnancy was associated with an increased risk of 5-year graft loss. For the fetus, there is value to discontinuing MPA anytime prior to the second trimester. Adhering to current guidelines does not negatively affect graft survival. © Copyright 2016 The American Society of Transplantation and the American Society of Transplant Surgeons.

To assess the risk of adverse pregnancy outcomes in subsequent pregnancies among women treated with methotrexate for ectopic pregnancy. In a retrospective single-center study, data were assessed for women treated with methotrexate for ectopic pregnancy at Asaf Harofe Medical Center, Zerifin, Israel, between May 2004 and May 2014. Overall, 226 women were treated with methotrexate for ectopic pregnancy and subsequently conceived. The median time from treatment to conception was 10 months (range 1-120 months), and 127 women conceived within 12 months of treatment. Except for early missed abortion-which affected 23 (10.2%) pregnancies-adverse pregnancy outcomes such as fetal malformations were rare. The frequency of early abortion was lowest for women who conceived within 6 months of treatment with methotrexate (3/93, 3.2%), increased between 6 and 23 months (15/83, 18.1%), and remained high thereafter (7/50, 14.0%; P=0.006). The frequency of fetal malformation in a subsequent pregnancy was low among women treated with methotrexate for ectopic pregnancy. The frequency of early missed abortion was lowest during the first 6 months after treatment with methotrexate. © 2017 International Federation of Gynecology and Obstetrics.

To elucidate the impact of unicornuate uteri on pregnancy outcomes as evidenced by historical and contemporary studies. Publications related to unicornuate uterus were identified through MEDLINE and other bibliographic databases. Literature review in an academic research environment. Premenopausal women with confirmed unicornuate uterus based on surgical or radiological evidence who were undergoing gynecologic and obstetrical care. None. Rates of ectopic pregnancy, miscarriage, preterm delivery, intrauterine fetal demise, and live birth. Our review revealed 20 studies of varying size and design that had commented on pregnancy outcomes in unicornuate uteri. These studies ranged in date from 1953 to 2006 and from a sample size of one to 55 patients. In total, we examined 290 women with unicornuate uterus reported in the literature. Of those patients, 175 conceived, to carry a total of 468 pregnancies. Incidence data in the literature reveal that unicornuate uterus occurs in 1:4020 women in the general population; the anomaly, however, is significantly more common in infertile women, as in women with repeated poor outcomes. Our review revealed rates of 2.7% ectopic pregnancy, 24.3% first trimester abortion,9.7% second trimester abortion, 20.1% preterm delivery, 3.8% intrauterine fetal demise, and 51.5%live birth [corrected]. Unicornuate uterus is a Mullerian anomaly with prognostic implications for poorer outcomes during pregnancy. The rates of adverse outcomes have likely been historically overestimated. Although it is unclear whether interventions before conception or early in pregnancy such as resection of the rudimentary horn and prophylactic cervical cerclage decidedly improve obstetrical outcomes, current practice suggests that such interventions may be helpful. Women presenting with a history of this anomaly should be considered high-risk obstetrical patients.

Plasma 25-hydroxyvitamin D (P-25OHD) concentrations may affect pregnancy outcomes. To elucidate this further, we studied the effects of pre-conception P-25OHD concentrations on chances for pregnancy as well as the effects of P-25OHD during pregnancy on the risk of miscarriage, birth weight and length, Apgar score and head circumference. Moreover, we studied whether pregnancy and breastfeeding patterns affect maternal P-25OHD concentrations. A total of 153 healthy Caucasian women with pregnancy plans were followed with measurements performed before pregnancy, at pregnancy weeks 11±2, 22±1 and 35±2 as well as 15±7, 129±12 and 280±15 days postpartum. Furthermore, 75 non-pregnant, age-matched women were followed in parallel as controls. The 203 women were aged 29 (25-35) years. At baseline, median P-25OHD was 59 nmol/l. Of these women, 31% had P-25OHD <50 nmol/l, whereas 12% had levels above 80 nmol/l. Within ∼6 months after inclusion, 63% conceived. P-25OHD was not associated with chances of conceiving or overall risk of miscarriage. However, women with a miscarriage in their second trimester (n=3) had lower P-25OHD concentrations at measurements performed in the first trimester compared with women without a miscarriage (P=0.03). P-25OHD before or during pregnancy was not associated with gestational length or infant parameters. Adjustments for possible confounders did not change the result. During pregnancy, P-25OHD changed significant over time, but similar changes occurred within the control group, indicating no effect of pregnancy per se (P=0.59). Overall, P-25OHD did not differ according to length of breastfeeding at 2 weeks, and 4 and 9 months postpartum, although women breastfeeding for >9 months had lower P-25OHD levels at the last visit compared with the controls. P-25OHD concentrations did not affect fertility or pregnancy outcomes, although low P-25OHD may be associated with an increased risk of late miscarriage.

Maternal obesity has been shown to affect reproductive function and pregnancy outcomes following in vitro fertilization. More recently, studies have demonstrated lower live birth rates after single blastocyst transfer (SBT) in patients who are overweight or obese. However, the impact of morbid obesity on pregnancy outcomes after SBT has not been well elucidated. The present study aimed to determine whether morbid obesity has a detrimental impact on pregnancy outcomes after SBT in a North American population. A retrospective, cohort study including 520 nulliparous and multiparous women undergoing top-quality SBT between August 2010 and March 2014 at a University Health Centre in North America was conducted. Primary outcomes included: miscarriage rate, clinical pregnancy rate, and live birth rate. Subjects were divided into different BMI categories (kg/m 2 ), including <20, 20-24.9, 25.0-29.9, 30-40, and 40 or more. The miscarriage rate per pregnancy for each group, respectively, was 36, 64, 59, 61, and 50% (p = 0.16); the clinical pregnancy (per patient) rate per group was 36, 52, 38, 26, and 10% (p = 0.009); and the live birth rate (per patient) per group was 35, 50, 38, 26 and 10% (p = 0.03). Morbid obesity is a strong and independent predictor of poor pregnancy outcomes in patients undergoing top-quality SBT.

Studies on pregnancy intentions and their consequences have yielded mixed results. Here, we comprehensively analyzed the maternal characteristics, health behaviors before and during pregnancy, as well as pregnancy and birth outcomes, across three different pregnancy planning status in 861 women participating in an ongoing Asian mother-offspring cohort study. At 26-28 weeks' gestation, the women's intention and enthusiasm toward their pregnancy were used to classify their pregnancy into planned or unplanned, and unplanned pregnancy was further subdivided into mistimed or unintended. Data on maternal characteristics, health behaviors, and pregnancy outcomes up to that stage were recorded. After delivery, birth outcomes of the offspring were recorded. Linear and logistic regression analyses were performed. Overall, 56 % had a planned pregnancy, 39 % mistimed, and 5 % unintended. Compared to women who planned their pregnancy, women with mistimed pregnancy had higher body mass index and were more likely to have cigarette smoke exposure and less likely to have folic acid supplementation. At 26-28 weeks' gestation, unintended pregnancy was associated with increased anxiety. Neonates of mistimed pregnancy had shorter birth length compared to those of planned pregnancy, even after adjustment for maternal baseline demographics. These findings suggest that mothers who did not plan their pregnancy had less desirable characteristics or health behaviors before and during pregnancy and poorer pregnancy and birth outcomes. Shorter birth length in mistimed pregnancy may be attributed to maternal behaviors before or in the early stages of pregnancy, therefore highlighting the importance of preconception health promotion and screening for women of child-bearing age.

At 26-28 weeks’ gestation, the women’s intention and enthusiasm towards their pregnancy were used to classify their pregnancy into planned or unplanned, and unplanned pregnancy was further subdivided into mistimed or unintended. Data on maternal characteristics, health behaviors, and pregnancy outcomes up to that stage, were recorded. After delivery, birth outcomes of the offspring were recorded. Linear and logistic regression analyses were performed. Overall, 56% had a planned pregnancy, 39% mistimed, and 5% unintended. Compared to women who planned their pregnancy, women with mistimed pregnancy had higher body mass index, and were more likely to have cigarette smoke exposure and less likely to have folic acid supplementation. At 26-28 weeks’ gestation, unintended pregnancy was associated with increased anxiety. Neonates of mistimed pregnancy had shorter birth length compared to those of planned pregnancy, even after adjustment for maternal baseline demographics. These findings suggest that mothers who did not plan their pregnancy had less desirable characteristics or health behaviors before and during pregnancy, and poorer pregnancy and birth outcomes. Shorter birth length in mistimed pregnancy may be attributed to maternal behaviors before or in the early stages of pregnancy, therefore highlighting the importance of preconception health promotion and screening for women of child-bearing age.

To evaluate the obstetric and perinatal outcomes evolution of triplet pregnancies. A prospective observational study was conducted in triplet pregnancies delivered over 16 years in a tertiary obstetric center with differentiated perinatal support. Evaluation of demographic factors, obstetric complications, gestational age at delivery, mode of delivery, birth weight and immediate newborn outcome were done over a 16 years period. A global characterization of the sample was performed considering the listed parameters. Variables were categorized in three groups according to year of occurrence: 1996-2000, 2001-2006, 2007-2011, and all parameters were compared. Of the 33 triplets included, 72.7% resulted from induced pregnancies. All except one patient received prenatal corticosteroids and five received tocolytics. All women delivered prenatally and no significant differences were seen in the mean gestational age at delivery or birth weight towards time. There were three intrauterine fetal deaths. Neonatal immediate outcomes were not significantly different over the years. Despite remarkable progresses in perinatal and neonatal cares, no noticeable impact in triplet gestations' outcomes was seen, sustaining that triplets should be avoided due to their great risk of prematurity and neonatal morbidities, either by limiting the numbers of embryos transferred or by fetal reduction.

Elevated lipid levels during late pregnancy are associated with complications and adverse outcome for both mother and newborn. However, it is inconclusive whether a disturbed lipid profile during early pregnancy has similar negative associations. Our objective was to investigate whether nonfasting maternal total cholesterol and triglyceride levels during early pregnancy are associated with six major adverse pregnancy outcomes. Data were derived from the Amsterdam Born Children and Their Development (ABCD) cohort study. Random blood samples of nonfasting total cholesterol and triglyceride levels were determined during early gestation (median = 13, interquartile range = 12-14 wk). Outcome measures were pregnancy-induced hypertension (PIH), preeclampsia, preterm birth, small/large for gestational age (SGA/LGA), and child loss. Only nondiabetic women with singleton deliveries were included; the baseline sample consisted of 4008 women. Analysis for PIH and preeclampsia were performed in nulliparous women only (n = 2037). Mean (sd) triglyceride and total cholesterol levels were 1.33 (0.55) and 4.98 (0.87) mmol/liter, respectively. The incidence of pregnancy complications and perinatal outcomes were as follows: PIH, 4.9%; preeclampsia, 3.7%; preterm birth, 5.3%; SGA, 9.3%; LGA, 9.3%; and child loss, 1.4%. After adjustments, every unit increase in triglycerides was linearly associated with an increased risk of PIH [odds ratio (OR) = 1.60, P = 0.021], preeclampsia (OR = 1.69, P = 0.018), LGA (OR = 1.48, P < 0.001), and induced preterm delivery (OR = 1.69, P = 0.006). No associations were found for SGA or child loss. Total cholesterol was not associated with any of the outcome measures. Elevated maternal triglyceride levels measured during early pregnancy are associated with pregnancy complications and adverse pregnancy outcomes. These results suggest that future lifestyle programs in women of reproductive age with a focus on lowering triglyceride levels (i.e. diet, weight

The successful development of chemotherapy enabled a fertilitysparing treatment for patients with trophoblastic neoplasia. After disease remission, the outcome of a subsequent pregnancy becomes a great concern for these women. To analyze existing studies in the literature that describe the reproductive outcomes of patients with trophoblastic neoplasia treated with chemotherapy. Systematic review was performed searching for articles on Medline/ Pubmed, Lilacs and Cochrane Library databases, using the terms "gestational trophoblastic disease" and "pregnancy outcome". A total of 18 articles were included. No evidence of decreased fertility after chemotherapy for trophoblastic neoplasia was observed. The abortion rates in patients who conceived within 6 months after chemotherapy was higher compared to those who waited longer. Some studies showed increased rates of stillbirth and repeat hydatidiform moles. Only one work showed increased congenital abnormalities. The pregnancies conceived after chemotherapy for trophoblastic neoplasia should be followed with clinical surveillance due to higher rates of some pregnancy complications. However, studies in the literature provide reassuring data about reproductive outcomes of these patients.

As conflicting data exist concerning the safety of induction of labor (IoL) in women with previous single lower segment cesarean section (CS), we aimed to assess pregnancy outcome following IoL in such patient population. All singleton pregnancies with previous single CS which underwent IoL during 2008-2012 were included (study group). Their pregnancy outcome was compared to those pregnancies with previous single CS that admitted with spontaneous onset of labor (control group). Overall, 1898 pregnancies were eligible, of them, 259 underwent IoL, and 1639 were admitted with spontaneous onset of labor. Parity, gestational age at delivery and birthweight were similar. Women in the study group were more likely to undergo CS mainly due to labor dystocia (8.1 versus 3.7%, p < 0.01). The rate of CS due to non-reassuring fetal heart rate was similar. No difference was found in the rate of uterine rupture/dehiscence. Short-term neonatal outcome was similar between the groups. On multivariable logistic regression analysis, IoL was not independently associated with uterine rupture (OR 1.33, 95% C.I 0.46-3.84, p = 0.59). Our data suggest that IoL in women with one previous low segment CS neither increases the risk of uterine rupture nor adversely affects immediate neonatal outcome.

Bipolar Disorder in Pregnancy: A Review of Pregnancy Outcomes.

Women with bipolar disorder may benefit from continuation of their medications during pregnancy, but there may be risks to the fetus associated with some of these medications. This article examines the evidence relating to the effect of bipolar disorder and pharmacologic treatments for bipolar disorder on pregnancy outcomes. MEDLINE, CINAHL, ProQuest Dissertation & Theses, and the Cochrane Database of Systematic Reviews were searched for English-language studies published between 2000 and 2017, excluding case reports and integrative reviews. Twenty articles that met inclusion criteria were included in this review. Women with bipolar disorder have a higher risk for pregnancy complications and congenital abnormalities than do women without bipolar disorder. In addition, illness relapse can occur if psychotropic medications are discontinued. There are limited data to recommend discontinuing lithium, lamotrigine, or carbamazepine during pregnancy. Valproic acid is not recommended during pregnancy due to increased odds of neural tube defects associated with its use. Atypical antipsychotics are used more frequently during pregnancy, with mixed evidence regarding an association between these agents and congenital malformations or preterm birth. The knowledge of benefits and risks of bipolar disorder and its treatment can help women and health care providers make individualized decisions. Prenatal care providers can discuss the evidence about safety of medications used to treat bipolar disorder with women in collaboration with their mental health care providers. In addition, women being treated for bipolar disorder require close monitoring for depressive and manic/hypomanic episodes that impact pregnancy outcomes. © 2017 by the American College of Nurse-Midwives.

To examine the relationship between asthmatic pregnancies and selected maternal and neonatal outcomes in a representative cohort. A retrospective cohort study was conducted at the Aga Khan University Hospital during the year 2004. A random selection was made of 65 asthmatic and 63 non-asthmatic singleton births. The neonatal outcomes studied were birth weight, premature birth and Apgar scores at 1 and 5 minutes. The maternal outcomes studied were number of hospital admissions, and number of documented UTI during the studied pregnancy and past history of abortions and stillbirths. The mean age of asthmatics and nonasthmatics were 28.0 +/- 4.9 years and 27.7 +/- 3.6 years respectively. The average parity among asthmatic women was 2.97 while that in controls was 2.57 (p < 0.137). Neonates born to asthmatic mothers had shorter mean gestational age with increased risk of premature birth and lower Apgar scores. Asthmatic mothers had a greater risk of abortions and low birth weight babies. They also had higher rates of UTIs and hospital admissions. Asthmatic pregnancies are more likely to result in abortion, premature delivery and low birth weight babies. The asthmatic pregnancies were also linked with higher rates of maternal UTI. Thcrefore a more vigilant monitoring is required in asthmatic pregnancies.

Background: More and more infertile patients have accepted the assisted reproductive technique (ART) therapy. Concerns have been raised over an increased risk of adverse maternal outcomes in ART populations as compared with natural conception (NC). Objective: The aim was to improve the ART in clinicial work and to reduce the incidence of pregnancy complications in ART group according to analyzing the reasons of high incidence of pregnancy complications in ART group, comparing the incidence of pregnancy complications in different controlled ovarian hyperstimulation (COH) programs and evaluating the effects of ART which attribute to adverse pregnancy outcomes. Materials and Methods: In this prospective population-based cohort study,3216 pregnant women with gestational age ≤12 weeks, regular antenatal examination,and ultrasound identification of intrauterine pregnancy were enrolled from January 2010 to June 2013. According to having ART history, the participantswere divided into two groups: ART group (contains fresh embryo transfer group or frozen-thawed embryo transfer group) and NC group. We compared the incidence of pregnancy complications between different groups and evaluated the factors which could affect the occurrence of these complications. Results: When compared to NC group, significantly increased rates of gestational diabetes mellitus (GDM) (p<0.01), preeclampsia (PE) (p<0.01) and intrahepatic cholestasis of pregnancy (ICP) (p˂0.01) were observed in ART group. There was no significant difference in the incidence of birth defect between the two groups (p=0.07). Multiple pregnancies and Gonadotropin (Gn) were risk factors in GDM, PE, and ICP. The exogenous progesterone treatment had no effect on GDM, PE or ICP. Conclusion: ART increases the risk of adverse maternal complications such as GDM, PE and ICP. The dosages of Gn should be reduced to an extent and the number of embryo implantation should be controlled. Exogenous progesterone treatment is safe

To assess the present status of resident duty hours in obstetrics and gynecology, identify existing policies concerning work schedules during pregnancy, and evaluate pregnancy outcome in female house officers. A questionnaire-based study was administered to residents taking the 2001 Council on Residency Education in Obstetrics and Gynecology examination. More than 90% of the residents reported that their institution had a maternity leave policy. The leave was usually 4-8 weeks long and was paid. Nearly 95% of residents reported that they had to take over the work of residents on maternity leave. Most women residents worked more than 80 hours weekly throughout pregnancy, and few took time off before delivery. Most pregnancies occurred during the fourth year of training and did not seem to be adversely affected by the long work hours. This study, performed before the institution of the new Accreditation Council for Graduate Medical Education resident duty hour policies, demonstrated that, although women house officers continued to work more than 80 hours per week during pregnancy, most had a good pregnancy outcome. Nevertheless, there was a higher frequency of preterm labor, preeclampsia, and fetal growth restriction in female residents than in spouses or partners of male residents.

Urinary tract infections (UTIs) during pregnancy are among the commonest health problems world wide, specially in developing countries, including Egypt. It has several adverse outcomes not only on the mother but also on the fetus as well.. The aim of this study is to determine the incidence of UTIs during pregnancy, study the main risk factors associated with such infections and find the impact of these infections on some pregnancy outcomes namely the gestational age and birth weight. A follow-up study on 249 pregnant women attending the ante natal care clinic at Zagazig university hospital. They were recruited over a period from 1st of September to 30th of or November, 2005. The outcome could be recorded for 201 of them. Data were collected through a pretested questionnaire, repeated urine analyses and recording of outcome of pregnancy. The study revealed that the incidence of UTIs during pregnancy was 31.3%. The commonest organisms were Klebsiella and E-coli. Several socio-demographic characteristics were found significantly associated with UTIs, age being 30 years and more, illiterates and low educational level, low socio-economic level and those with unsatisfactory personal hygiene and those using underwear clothes other than cotton. Significant associations with UTIs were also found in multigravidae 4th and more, those having more than one child and those who previously suffered UTIs. The only predicting variable with UTIs was low socio-economic level. The study revealed that the probability of delivering premature infants and low birth weights was significantly higher among those who experienced UTIs during pregnancy. Multivariate analysis revealed that UTI was one of the main contributors to pre-mature deliveries. Urinary tract infections with pregnancy still constitute a big problem with high incidence. It has a great impact on pregnancy outcome mainly pre-mature labor. So, the study recommends health education about personal hygiene, repeated urine

Restless legs syndrome (RLS) is a commonly occurring neurologic disorder that affects up to one third of women during pregnancy. RLS has been associated with increased sympathetic tone in the nonpregnant population. We examined whether a RLS surrogate is associated with a higher prevalence of pregnancy and neonatal outcomes. Data were analyzed from a cross-sectional survey of 1000 women interviewed soon after delivery by using an RLS surrogate question. Women were asked how frequently (0 = none, 1 = rarely [<1 time/week], 2 = sometimes [1-2 times/week], 3 = frequently [3-4 times/week], and 4 = always [5-7 times/week]) they had "experienced jumpy or jerky leg movements" in the last 3 months of pregnancy. Clinical charts were reviewed to obtain relevant demographic and clinical data, including the presence of gestational hypertensive disorders and neonatal outcomes at birth. Subjects who "always" experienced RLS were compared with subjects experiencing symptoms less frequently or not at all with respect to prevalence of gestational hypertensive disorder. The mean ([SD]) age, prepregnancy body mass index (BMI), and BMI at delivery were 29.0 (6.1) years, 26.1 (6.2) kg/m(2), and 32.0 (6.3) kg/m(2), respectively. The overall prevalence of the RLS surrogate (jumpy or jerky leg movements) was 35.5% with the following distribution on a Likert scale: score 1 = 6.4%; score 2 = 10.2%; score 3 = 8.1%; and score 4 = 10.8%. Chronic hypertension was present in 2.1%, pregnancy-induced hypertension in 9.5%, and preeclampsia in 4.5% of respondents. Subjects who reported "always" having sensations of jumpy or jerky legs were more likely to have gestational hypertensive disorders compared with those who reported less frequent occurrence of the symptoms. Adjusted odds ratios were 3.74 (95% CI, 1.31-10.72; P = 0.014) for chronic hypertension; 1.26 (95% CI, 0.65-2.46; P = 0.487) for pregnancy-induced hypertension; and 2.15 (95% CI, 0.97-4.75; P = 0.060) for preeclampsia.

Because subclinical hypothyroidism (thyroid-stimulating hormone [TSH] > 4.5 IU/mL) is associated with adverse pregnancy outcome, including early pregnancy loss, TSH is recommended to be titrated to ≤2.5 mIU/L in levothyroxine-treated women before pregnancy. The purpose of this study was to determine whether borderline-subclinical hypothyroidism (borderline-SCH; 2.5 < TSH ≤ 4.5 IU/mL) affects the outcome of subsequent pregnancies in women with unexplained recurrent pregnancy loss (uRPL). After workup for antinuclear antibody (ANA), anti-phospholipid syndrome, thrombophilia, uterine abnormalities, hormone disorders, and/or chromosomal abnormalities, 317 women with a history of uRPL were enrolled. The women were classified into two groups: borderline-SCH, and euthyroidism (0.3 ≤ TSH ≤ 2.5 IU/mL). All women had normal serum free thyroxine (T4) and did not receive levothyroxine before or during the subsequent pregnancy. There were no significant differences in age, number of previous pregnancy losses, number of live births, or body mass index between the borderline-SCH (n = 56) and the euthyroid (n = 261) groups, but the rate of ANA positivity differed significantly (53.6% vs 33.7%, respectively; P = 0.005). The subsequent pregnancy rate did not differ between the two groups (55.4%, 31/56 vs 51.3%, 134/261, respectively). The pregnancy loss rate (<22 weeks of gestation) tended to be higher in the borderline-SCH than the euthyroid group (29.0%, 9/31 vs 17.9%, 24/134), although not significantly so (P = 0.16). Although some subset of uRPL is though to be due to as-yet-unidentified cause(s), borderline-SCH is unlikely to be involved in uRPL. © 2017 Japan Society of Obstetrics and Gynecology.

Major malformation risk, pregnancy outcomes, and neurodevelopmental outcomes associated with metformin use during pregnancy.

PubMed

Andrade, Chittaranjan

2016-04-01

There are several reasons why metformin treatment may be considered for women in neuropsychiatric practice. These include prevention or attenuation of antipsychotic-associated weight gain, prevention or treatment of gestational diabetes mellitus (GDM), treatment of type 2 diabetes mellitus, and improvement of conception chances and pregnancy outcomes in the presence of polycystic ovarian disease (PCOD). This article examines the benefits and risks associated with metformin use during pregnancy. The available data suggest that metformin exposure during the first trimester is not associated with major congenital malformations; that metformin reduces the risk of early pregnancy loss, preeclampsia, preterm delivery, and GDM in women with PCOD; that metformin is associated with at least comparable benefits relative to insulin treatment in women with mild GDM; and that neurodevelopmental outcomes at age 1.5-2.5 years are comparable after gestational exposure to metformin and insulin. Whereas study designs were not always ideal and sample sizes were mostly small to modest, the study findings are more encouraging than discouraging and can guide shared decision-making in women who are receiving or may need metformin during pregnancy. © Copyright 2016 Physicians Postgraduate Press, Inc.

To compare the obstetric outcomes between pregnant women affected by beta-thalassemia trait and normal controls. A retrospective cohort study was conducted on singleton pregnant women complicated by beta-thalassemia trait and normal controls, randomly selected with the controls-to-case ratio of 2:1. All were low-risk pregnancies without underlying medical diseases and fetal anomalies. The pregnancies undergoing invasive prenatal diagnosis were excluded. A total of 597 pregnant women with beta-thalassemia trait and 1194 controls were recruited. Baseline characteristics and maternal outcomes in the two groups were similar, except that hemoglobin levels were slightly lower in the study group. The prevalence of small for gestational age and preterm birth tended to be higher in the study group but not reached the significant levels but the rate of low birth weight was significantly higher in the study group (relative risk 1.25; 95 % CI 1.00-1.57). Additionally, abortion rate was also significantly higher in the study group (relative risk 3.25; 95 % CI 1.35-7.80). Beta-thalassemia trait could minimally, but significantly, increase risk of low birth weight but did not increase rates of maternal adverse outcomes.

Quadruplet pregnancy: contemporary management and outcome.

Quadruplets are occurring more frequently as assisted-reproduction techniques improve fertility in couples previously unable to conceive. Ten quadruplet pregnancies cared for in one perinatal practice over 5 years had excellent outcome. The mean gestational age at delivery was 32.5 weeks, compared with approximately 30 weeks in the literature. There were no perinatal deaths and no long-term morbidity. Our patients were compared with a series of 57 consecutive patients with quadruplet pregnancies monitored by a home monitoring system. Parity of 1 or more appeared to improve outcome. Pregnancy-induced hypertension occurred in nine of our pregnancies and necessitated delivery in seven instances. Fetal distress was responsible for two deliveries and uncontrollable preterm labor for only one. Key points in our management protocol include prophylactic use of low-dose aspirin, home contraction monitoring, use of terbutaline pump tocolysis, and bed rest at home starting at 16 weeks.

To evaluate the prevalence of chronic endometritis (CE) in women with recurrent pregnancy loss (RPL) and compare pregnancy outcomes in women with and without CE. Case-control observational study. Academic fertility practice. Women with two or more pregnancy losses. Hematoxylin and eosin (H & E) staining was performed on all endometrial biopsies and plasma cells were identified by morphology. Immunohistochemical (IHC) staining for CD138 was later applied to all tissue samples. Charts were reviewed to evaluate the outcome of the next clinical intrauterine pregnancy. Miscarriage rate and live birth rate. A total of 107 women met inclusion criteria. The use of CD138 IHC staining resulted in a significantly higher prevalence of CE compared with the use of H & E staining and morphological assessment alone (56% [60/107] vs. 13% [14/107]). The 51 women with untreated CE were compared with the 45 women without CE by CD138 staining. Among those women with a subsequent pregnancy, the live birth rate in the next clinical intrauterine pregnancy after endometrial evaluation was 67.6% (23/34) in women with untreated CE and 87.1% (27/31) in women without CE. Age, body mass index (BMI), results of RPL evaluation, and number of prior losses were not significantly different between the two groups. CD138 IHC staining of endometrial biopsies in women with RPL provides increased sensitivity when screening for CE compared with H & E staining and morphological assessment alone. Untreated CE may contribute to poor pregnancy outcomes and deserves further investigation in a larger cohort. Copyright © 2015 American Society for Reproductive Medicine. Published by Elsevier Inc.

Maternal obesity has long been correlated with an increased risk of chronic hypertension and diabetes prior to pregnancy and adverse pregnancy outcomes including preeclampsia, gestational diabetes, fetal macrosomia, Cesarean deliveries, postpartum endometritis and a prolonged hospital stay To determine the effect of maternal pre-pregnancy obesity on pregnancy outcomes Methods: One hundred and twenty two women were recruited in the study. The patients were allocated into two groups, group 1 obese patients (68) BMI 30 or more and group 2 non obese patients (54) BMI between 19.8-24.9. About two - third of the study group were having mild obesity, moderate obesity comprised about 28% and about 4% only was morbidly obese. Hypertensive disorders were nine folds more among obese women (R.R 4.74). Obese pregnant women were significantly more prone to have gestational diabetes (R.R 6.35). Even anemia was significantly more amongst Obese women when compared to non obese ones (29/68, R.R 3.84). Ante partum hemorrhage had significantly more in obese women (R.R 3.14). There was no increased risk for PROM (R.R 0.71). Moreover The macrosomic babies were extremely commoner among obese (R.R 9.1). Pre-pregnancy obesity is a risk factor for gestational diabetes, preeclampsia, labor induction, cesarean section for fetal distress, and wound infection. They should be considered as high risk and counseled accordingly.

Low birth weight due to preterm delivery or intrauterine growth restriction (IUGR) is the strongest factor contributing to prenatal, neonatal, and postnatal mortality. Maternal-fetal attachment plays a significant role in maternal and fetal health. Health practices performed by the mother during pregnancy constitute one of the factors that may affect neonatal outcomes. The present study was conducted to identify the relationship between maternal-fetal attachment and health practices during pregnancy with neonatal outcomes. This cross-sectional study was conducted on 315 pregnant women with a gestational age of 33-41 weeks who presented to hospitals in Sirjan (Iran) between December 2014 and February 2015. The data collection tools used included the Health Practices in Pregnancy Questionnaire and the Maternal Fetal Attachment Scale. Data were analyzed using IBM-SPSS version 20, focusing on the Pearson product-moment correlation and the logistic regression model. Statistical significance was set to p<0.05. The mean score of maternal-fetal attachment was 60.34, and the mean score of health practices was 123.57. The mean birth weight of the neonates was 3052.38 g. Health practices (p<0.05, r=0.11) and maternal-fetal attachment (p<0.01, r=0.23) were positively and significantly correlated with neonatal outcomes. A significant positive relationship was also observed between maternal-fetal attachment and neonatal outcomes. No significant relationships were observed between health practices during pregnancy and neonatal outcomes. Maternal-fetal attachment and health practices during pregnancy are positively and significantly correlated with neonatal outcomes.

Pregnancy may precipitate acute episodes of thrombotic thrombocytopenic purpura (TTP), but pregnancy outcomes in women who have recovered from acquired TTP are not well documented. We analyzed pregnancy outcomes following recovery from TTP associated with acquired, severe ADAMTS13 deficiency (ADAMTS13 activity <10%) in women enrolled in the Oklahoma TTP-HUS Registry from 1995 to 2012. We also systematically searched for published reports on outcomes of pregnancies following recovery from TTP associated with acquired, severe ADAMTS13 deficiency. Ten women in the Oklahoma Registry had 16 subsequent pregnancies from 1999 to 2013. Two women had recurrent TTP, which occurred 9 and 29 days postpartum. Five of 16 pregnancies (31%, 95% confidence interval, 11%-59%) in 3 women were complicated by preeclampsia, a frequency greater than US population estimates (2.1%-3.2%). Thirteen (81%) pregnancies resulted in normal children. The literature search identified 382 articles. Only 6 articles reported pregnancies in women who had recovered from TTP associated with acquired, severe ADAMTS13 deficiency, describing 10 pregnancies in 8 women. TTP recurred in 6 pregnancies. Conclusions: With prospective complete follow-up, recurrent TTP complicating subsequent pregnancies in Oklahoma patients is uncommon, but the occurrence of preeclampsia may be increased. Most pregnancies following recovery from TTP in Oklahoma patients result in normal children. PMID:24398329

To describe the antenatal complications, mode of delivery and outcome of pregnancy in women with spina bifida. Case series of women known to have attended the spina bifida clinic at the Royal Children's Hospital. Medical records, postal questionnaire and telephone interview were utilized to collect data on the effect of pregnancy on the health of women and the effect of spina bifida on pregnancy outcome. Of 207 women born between 1945 and 1975, 23 reported having a pregnancy, and 17 who had completed pregnancies agreed to participate. The 17 women had a total of 29 pregnancies, with 23 pregnancies progressing to births. Fourteen of 17 women had antenatal admissions, with wheelchair-dependent women requiring more-frequent and longer admissions. Recurrent urinary infections in pregnancy occurred in women with a prior history of urinary infections; stomal problems occurred but were not serious; mobility was reduced for two women during pregnancy, with full recovery afterwards; and preexisting pressure sores worsened during pregnancy. Vaginal deliveries occurred in one in five pregnancies of women who were wheelchair dependent and in ten of eighteen pregnancies in independently mobile women, including seven of eight pregnancies of independently mobile women without ileal conduits. Cesarean sections were accompanied by postoperative complications in 10 women. Women with spina bifida who become pregnant generally have a positive outcome, with relatively low complication rates.

We analyzed data from the 2006-2007 Canadian Maternity Experiences Survey, comprising a cross-sectional representative sample of 6,421 childbearing women. Multiple logistic regression assessed the association between adverse outcomes and three indicators of partner disengagement: (1) partner did not want the pregnancy, (2) partner argued more than usual in the year prior to the baby's birth, and (3) partner was absent at the delivery. Of all respondents, 3.8% had partners who did not want the pregnancy, 16.1% argued more than usual with their partner in the past year, and 7.6% had partners who were absent at the delivery. Women whose partner did not want the pregnancy were more likely to report intimate partner violence (IPV) (adjusted odds ratio [AOR] 3.55; 95% confidence interval [95% CI] 2.36-5.14), elevated depressive symptoms in the extended postpartum period (AOR 2.56, 95% CI 1.70-3.83), and nonroutine child healthcare visits after birth (AOR 1.54, 95% CI 1.13-2.11). Women whose partner argued more in the past year had higher odds of IPV (AOR 4.82, 95% CI 3.69-6.30), elevated depressive symptoms in the extended postpartum period (AOR 3.63; 95% CI 2.84-4.64), and nonroutine child healthcare visits (AOR 1.49, 95% CI 1.26-1.77), after adjustment for potential confounders. Partner disengagement is common and is associated with adverse maternal and infant outcomes. Affected women may benefit from special assistance during pregnancy and after delivery.

Background  It is unclear how adherence to the Institute of Medicine's (IOM) guidelines for weight gain affects pregnancy outcomes. Objective  We investigated how weight gain outside the IOM's recommendations affects the risks of adverse pregnancy outcomes. Study Design  We performed a secondary analysis of a prospective cohort study including singleton, nonanomalous fetuses. The risks of small for gestational age (SGA), macrosomia, preeclampsia, cesarean delivery, gestational diabetes, or preterm birth were calculated for patients who gained weight below or above the IOM's recommendations based on body mass index category. A time-to-event analysis was performed to account for gestational age at delivery. A Cox proportional model was fit to estimate hazard ratios accounting for possible confounders. Results  Women who gained weight below recommendations were 2.5 times more likely to deliver SGA and twice as likely to deliver preterm. Normal-weight patients who gained below recommendations were 2.5 times more likely to deliver SGA and twice as likely to deliver preterm. Obese patients who gained inadequate weight were 2.5 times more likely to deliver SGA. Conclusion  Among normal-weight patients, adhering to IOM recommendations may prevent growth abnormalities and preterm delivery. Among obese patients, a minimum weight gain requirement may prevent SGA infants. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

The aim of this work was to evaluate the effects of extreme body mass index (BMI) on assisted reproductive treatment outcome and pregnancy outcome. This is a descriptive cohort study that evaluated 8,145 consecutive in-vitro fertilisation/intracytoplasmic sperm injection-embryo transfer (IVF/ICSI-ET) cycles in which BMI were known, from July 1997 to June 2005 in an inner London major fertility clinic. The data were collected prospectively and analysed retrospectively on women undergoing IVF/ICSI and ET. Patients' weight and height were established prior to treatment. IVF/ICSI treatment was then started using either a long or an antagonist protocol. Patients were divided into five groups: Group A (BMI < 19); Group B (BMI between 19 and 25.9); Group C (BMI between 26 and 30.9); Group D (BMI between 31 and 35.9); Group E (BMI > 36). The main outcomes measured were number of eggs collected, fertilisation rate, number of embryos available for transfer, pregnancy rate (PR), live-birth rate (LBR) and miscarriage rate (MR). The results showed no significant difference in the average number of days taking follicle stimulating hormone (FSH) for ovarian stimulation, the average amount of gonadotrophin used for stimulation, number of eggs collected and fertilisation rate. The pregnancy rate, miscarriage rate and the live-birth rate were not statistically different between all groups. However, in group E the miscarriage rate was significantly higher and the LBR was statistically lower compared with group B. We concluded that extreme BMI did not affect the super-ovulation outcome fertilisation rate and pregnancy rate. Women with a BMI > 35 had a higher miscarriage rate and hence a lower live-birth rate, but a reasonable pregnancy and live-birth rate can be achieved. For women with a BMI < 20 there was no difference in assisted reproduction treatment (ART) outcome and pregnancy outcome when compared with women with a normal BMI. This information should be used to advise patients

Data comparing pregnancy outcome in hyperthyroid women with euthyroid women are scarce. Hence, this study was carried out to assess the maternal and fetal outcome in pregnant women with hyperthyroidism to ascertain the effect of disease on pregnancy. This retrospective study was conducted over a period of 28 years. We compared the maternal and fetal outcomes of 208 hyperthyroid women with 403 healthy controls, between women with well-controlled and uncontrolled disease and amongst women diagnosed with hyperthyroidism before and during pregnancy. Maternal outcome: women with hyperthyroidism were at increased risk for preeclampsia (OR = 3.94), intrauterine growth restriction (OR = 2.16), spontaneous preterm labor (OR = 1.73), preterm birth (OR = 1.7), gestational diabetes mellitus (OR = 1.8), and cesarean delivery (OR = 1.47). Hyperthyroid women required induction of labor more frequently (OR = 3.61). Fetal outcome: newborns of hyperthyroid mothers had lower birth weight than normal ones (p = 0.0001). Women with uncontrolled disease had higher odds for still birth (OR = 8.42; 95% CI: 2.01-35.2) and lower birth weight (p = 0.0001). Obstetrical complications were higher in women with hyperthyroidism than normal women. Outcome was worsened by uncontrolled disease. Women with pregestational hyperthyroidism had better outcomes than those diagnosed with it during pregnancy. © 2014 S. Karger AG, Basel.

The use of antiandrogen drugs such as finasteride during pregnancy may carry the risk of birth defects, especially hypospadias. We report a 39-year-old woman, with 5 weeks unplanned pregnancy, the patient conceived while receiving daily dose of finasteride 2.5 mg for treatment of alopecia. The patient's partner was concurrently using finasteride for the same purpose. Ultrasound scans including detailed anatomy were normal throughout pregnancy and the fetal gender was detected to be male. The patient had her delivery at 38 +5 weeks' gestation, by elective cesarean section, a male infant with a weight of 3.58 kg and Apgar score of 9 and 10 at 1 and 5-min, respectively. The infant was healthy with no obvious dysmorphic features. In this case report, maternal use of finasteride in early pregnancy was not associated with external genitalia abnormalities of a male baby. Moreover, maternal exposure to the semen of partner who received finasteride did not adversely affect the short term neonatal outcomes. However, absence of apparent neonatal adverse effects in a single case report does not indicate safety of use. Population-based long term neonatal outcomes are yet to be established.

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

Potential confounding or effect modification by employment status is frequently overlooked in pregnancy outcome studies. To characterize how employed and non-employed women differ, we compared demographics, behaviors, and reproductive histories by maternal employment status for 8,343 mothers of control (non-malformed) infants in the National Birth Defects Prevention Study (1997-2007) and developed a multivariable model for employment status anytime during pregnancy and the 3 months before conception. Sixteen factors were independently associated with employment before or during pregnancy, including: maternal age, pre-pregnancy body mass index, pregnancy intention, periconceptional/first trimester smoking and alcohol consumption, and household income. Employment status was significantly associated with many common risk factors for adverse pregnancy outcomes. Pregnancy outcome studies should consider adjustment or stratification by employment status. In studies of occupational exposures, these differences may cause uncontrollable confounding if non-employed women are treated as unexposed instead of excluded from analysis. Am. J. Ind.

Lipids play an important role during pregnancy, and in this period major changes occur in lipoprotein metabolism. During the third trimester plasma cholesterol and triglyceride levels are substantially increased, returning to normal after delivery. Described associations between increased morbidity during pregnancy and excessive increases in plasma cholesterol and triglycerides. For this reason we have reviewed the relationship between lipid alterations, preeclampsia, gestational diabetes and preterm birth. The overall metabolic control can improve pregnancy outcomes, and the assessment of supraphysiological changes in lipid profile will classify pregnancy risk at a higher level, which would entail a stricter control.

2017-01-01

Research on the potential impact of air pollution on the human's health has increased rapidly in recent years. Several studies have suggested that exposure to air pollutants during period of pregnancy which is a crucial time point of mother-fetus development may have long-term and serious impact on adverse pregnancy outcomes. There is lack of review to evaluate the existed epidemiologic evidence on the associations between air pollutants and adverse pregnancy outcomes in China, so we conducted a review to explore the current epidemiological evidence on the effects of air pollutants to pregnancy outcomes and possible mechanisms during the pregnancy process. We used keywords to systematically search all the English and Chinese literatures on studies that were conducted in China. Exposure to air pollutants during pregnancy had shown there were harmful effects for different birth outcomes: preterm birth, low birth weight, stillbirth, birth defects, infertility, and macrosomia fetus. Results on the effects of air pollutants on adverse pregnancy outcomes are small and inconsistent because they vary in their design and methodology. The existed available evidence is compatible with either a small negative effect of air pollutants on pregnancy outcomes or with no effect; therefore, further studies are needed to confirm and quantify the possible associations and potential biologic mechanisms between air pollutants and pregnancy outcomes.

The aim of the study was to determine the fetal and neonatal outcomes of pregnancies conceived during the inactive phase of systemic lupus erythematosus (SLE). Fetal and neonatal outcomes in 75 pregnancies of 33 patients with SLE were analyzed. In 19 patients (57.6%) the SLE also had hematological autoimmune presentations prior to gestation, such as anemia, thrombopenia, garnulocytopenia, and antiphospholipid antibody and/or lupus anticoagulant (APA). Out of 75 pregnancies, 19 elective terminations were carried out because the disease was active or for non-medical reasons. The adverse fetal outcomes of those 56 pregnancies which occurred during the inactive phase were compared with those of the control patients. In SLE, the rates of spontaneous abortions (46.4%) and newborns with low (< 2500 gr) birthweight (36.7%) were found to increase roughly three times that of the controls and the perinatal fetal loss (16.7%) also increased significantly as compared with the control group (28.5 per thousand). APA noted at any time before pregnancy increased the low birthweight rate (75%) six fold and the perinatal loss (33.3%) more than ten fold but did not affect the rate of spontaneous abortions. Any kind of hemocytopenias without APA, noted before pregnancy did not worsen the fetal outcome in SLE. Neonatal lupus was diagnosed in 2 out of the 30 newborns. Our results suggest that among the hematologic manifestations of SLE presenting before pregnancy, APA can predict the high risks of low birthweight and perinatal fetal loss as opposed to hemocytopenias.

Does Exercise During Pregnancy Affect Placental Weight?: A Randomized Clinical Trial.

Placental weight (PW) is a measure commonly used to summarize growth and aspects of placental function. In a normal pregnancy, it is reasonable to assume that PW is related to aspects of the functional capacity of the placenta. The placenta, as the site for all maternal-fetal oxygen and nutrient exchange, influences birth weight and is thus central to a successful pregnancy outcome. PW is the most common way to characterize placental growth, which relates to placental function. With physical exercise becoming an integral part of life for many women, the question of whether exercise during pregnancy has an adverse effect on the growing fetus is very important. The aim was to examine the influence of an aerobic exercise program throughout pregnancy on PW among healthy pregnant women. A randomized control trial was used (registration trial number: NCT02420288). Women were randomized into an exercise group (EG; n = 33) or a control group (CG; n = 32) that received standard care. The EG trained 3 days/week (55-60 min/session) from gestational Weeks 9-11 until Weeks 38-39. The 85 training sessions involved aerobic, muscular and pelvic floor strength, and flexibility exercises. PW and other pregnancy outcomes were measured. There was high attendance to the exercise program, and no differences in the PW at delivery were observed between study groups (CG = 493.2 ± 119.6 g vs. EG = 495.4 ± 150 g, p = .95). A regular, supervised exercise program throughout pregnancy does not affect the PW in healthy pregnant women.

Gaucher disease (GD) may worsen during pregnancy, leading to the discussion of continuing treatment during pregnancy. We examined fetal outcomes of pregnancies reported in the Gaucher Outcome Survey, an international GD-specific registry established in 2010. A total of 453 pregnancies were reported. Most pregnancies (336/453, 74.2%) were in women who did not receive GD-specific treatment during pregnancy, while enzyme replacement therapy (ERT) was received during 117/453 (25.8%) pregnancies. No pregnancies exposed to substrate reduction therapy were reported. The percentage of normal outcomes (live birth delivered at term with no congenital abnormalities) was similar in untreated and treated pregnancies (92.9% vs. 91.4%). The percentage of spontaneous abortions in untreated pregnancies was 3.6% (95% CI, 1.9%- 6.2%) compared with 6.9% (95% CI, 3.0%-13.1%) in treated pregnancies (p=0.1866). In women who received velaglucerase alfa <1month prior to conception and/or during pregnancy, 34/36 (94.4%) pregnancies had normal outcomes and 2 (5.6%) ended in spontaneous abortion. Normal outcomes were observed in the 20 pregnancies with velaglucerase alfa exposure starting <1month prior to conception and continuing through all trimesters. These observations, in addition to information in the literature, suggest that continuation of ERT during pregnancy may be appropriate for GD patients.

Administrative claims and electronic health records are valuable resources for evaluating pharmaceutical effects during pregnancy. However, direct measures of gestational age are generally not available. Establishing a reliable approach to infer the duration and outcome of a pregnancy could improve pharmacovigilance activities. We developed and applied an algorithm to define pregnancy episodes in four observational databases: three US-based claims databases: Truven MarketScan® Commercial Claims and Encounters (CCAE), Truven MarketScan® Multi-state Medicaid (MDCD), and the Optum ClinFormatics® (Optum) database and one non-US database, the United Kingdom (UK) based Clinical Practice Research Datalink (CPRD). Pregnancy outcomes were classified as live births, stillbirths, abortions and ectopic pregnancies. Start dates were estimated using a derived hierarchy of available pregnancy markers, including records such as last menstrual period and nuchal ultrasound dates. Validation included clinical adjudication of 700 electronic Optum and CPRD pregnancy episode profiles to assess the operating characteristics of the algorithm, and a comparison of the algorithm’s Optum pregnancy start estimates to starts based on dates of assisted conception procedures. Distributions of pregnancy outcome types were similar across all four data sources and pregnancy episode lengths found were as expected for all outcomes, excepting term lengths in episodes that used amenorrhea and urine pregnancy tests for start estimation. Validation survey results found highest agreement between reviewer chosen and algorithm operating characteristics for questions assessing pregnancy status and accuracy of outcome category with 99–100% agreement for Optum and CPRD. Outcome date agreement within seven days in either direction ranged from 95–100%, while start date agreement within seven days in either direction ranged from 90–97%. In Optum validation sensitivity analysis, a total of 73% of

We sought to describe the prevalence, sociodemographic features, and antenatal/peripartum outcomes of multiple sclerosis (MS) in pregnancy. A retrospective cohort study was performed using deliveries in California from 2001 to 2009. Cases of MS as well as other morbidities were identified via ICD-9-CM code. Logistic regression was performed to adjust for potential confounders. About 1185 out of 4,424,049 deliveries were complicated by MS. MS prevalence increased with maternal age, with Caucasians comprising a higher proportion of MS subjects. MS subjects were older and more likely to have private insurance. Women with MS were more likely to have preexisting medical conditions such as asthma, chronic hypertension, thyroid disease, or cardiac disease. However, no significant antepartum and peripartum morbidities were found to be increased in patients with MS. Urinary tract infection, cesarean delivery, and induction of labor were slightly increased in MS patients. MS is a rare condition which is more likely to affect older Caucasian women of higher socioeconomic status and is associated with several preexisting medical conditions. MS, however, does not appear to pose significant increases in adverse pregnancy outcome. This suggests that pregnant patients with MS may likely experience an uneventful pregnancy.

Introduction: Patients with threatened miscarriage associated with adverse pregnancy outcomes because of associated pregnancy and labor complications. Objectives: To evaluate the effect of threatened miscarriage on early and late pregnancy outcome. Methods: A retrospective case–controlled study was performed on 89 women with threatened miscarriage (study group) at Maternity and Children Hospital Buraidah, KSA from January 2010 to December 2010. They were matched for age and parity to 45 cases (control group) attending route antenatal clinic at the same time. Data recorded included, demographic characteristics and detailed pregnancy outcome and ultrasound finding including gestational age, cardiac activity and subchorionic hematoma. Results: The overall adverse pregnancy outcome was significantly higher in the studied cases compared to the control group (p=015).The miscarriage rate was significantly higher in study group compared to the controls group, (16.9%vs 2.2%, p=0000). Preterm delivery, babies with low birth weight and premature rupture of membranes were significantly higher in the miscarriage group compared to the controls group, (15.7% vs 2.2%, p=0.001), (15.7% vs 2.2%), p=0.001) and (6.7%) vs 4.45), p=0.016). There were no significant differences in other pregnancy outcomes. Conclusion: threatened miscarriage is associated with increased incidence of adverse pregnancy outcome. The risk is specially increased in premature rupture of the membranes, preterm delivery and neonatal birth weight. PMID:23678307

Pregnancy outcome after use of cranberry in pregnancy – the Norwegian mother and child cohort study

PubMed Central

2013-01-01

Background Cranberry is one of the most commonly used herbs during pregnancy. The herb has been used traditionally against urinary tract infections. No studies are found that specifically address the risk of malformations after use of cranberry during pregnancy. The aim of the study was to investigate the safety of cranberry use during pregnancy, including any effects on congenital malformations and selected pregnancy outcomes. Methods The study is based on data from The Norwegian Mother and Child Cohort Study including more than 100,000 pregnancies from 1999 to 2008. Information on use of cranberry and socio-demographic factors was retrieved from three self-administered questionnaires completed by the women in pregnancy weeks 17 and 30, and 6 months after birth. Information on pregnancy outcomes was retrieved from the Medical Birth Registry of Norway. Results Among the 68,522 women in the study, 919 (1.3%) women had used cranberry while pregnant. We did not detect any increased risk of congenital malformations after use of cranberry. Furthermore, the use of cranberry was also not associated with increased risk for stillbirth/neonatal death, low birth weight, small for gestational age, preterm birth, low Apgar score (<7), neonatal infections or maternal vaginal bleeding in early pregnancy. Although an association was found between use of cranberry in late pregnancy and vaginal bleeding after pregnancy week 17, further sub-analyses of more severe bleeding outcomes did not support a significant risk. Conclusions The findings of this study, revealing no increased risk of malformations nor any of the following pregnancy outcomes; stillbirth/neonatal death, preterm delivery, low birth weight, small for gestational age, low Apgar score and neonatal infections are reassuring. However, maternal vaginal bleeding should be investigated further before any firm conclusion can be drawn. Treatment guidelines on asymptomatic bacteriuria in pregnancy recommend antimicrobial

Trials on diet and physical activity in pregnancy report on various outcomes. We aimed to assess the variations in outcomes reported and their quality in trials on lifestyle interventions in pregnancy. We searched major databases without language restrictions for randomized controlled trials on diet and physical activity-based interventions in pregnancy up to March 2015. Two independent reviewers undertook study selection and data extraction. We estimated the percentage of papers reporting 'critically important' and 'important' outcomes. We defined the quality of reporting as a proportion using a six-item questionnaire. Regression analysis was used to identify factors affecting this quality. Sixty-six randomized controlled trials were published in 78 papers (66 main, 12 secondary). Gestational diabetes (57.6%, 38/66), preterm birth (48.5%, 32/66) and cesarian section (60.6%, 40/66), were the commonly reported 'critically important' outcomes. Gestational weight gain (84.5%, 56/66) and birth weight (87.9%, 58/66) were reported in most papers, although not considered critically important. The median quality of reporting was 0.60 (interquartile range 0.25, 0.83) for a maximum score of one. Study and journal characteristics did not affect quality. Many studies on lifestyle interventions in pregnancy do not report critically important outcomes, highlighting the need for core outcome set development. © 2017 Japan Society of Obstetrics and Gynecology.

NTP Monograph: Developmental Effects and Pregnancy Outcomes Associated With Cancer Chemotherapy Use During Pregnancy.

PubMed

2013-05-01

The National Toxicology Program (NTP) Office of Health Assessment and Translation (OHAT) conducted an evaluation of the developmental effects and pregnancy outcomes associated with cancer chemotherapy use during pregnancy in humans. The final NTP monograph was completed in May 2013 (available at http:// ntp.niehs.nih.gov/go/36495). The incidence of cancer during pregnancy has been reported to occur from 17 to 100 per 100,000 pregnant women. Chemotherapy is a common treatment for cancer; however, most chemotherapy agents are classified as known or suspected human teratogens. Cancer chemotherapy use during pregnancy was selected for evaluation by the NTP because of the: (1) paucity of comprehensive reviews on the pregnancy outcomes following cancer chemotherapy use during pregnancy in humans, including the integration of the developmental animal toxicology literature with the observational studies in humans, and (2) growing public interest in the developmental effects of chemotherapy on offspring exposed to cancer chemotherapy during gestation due to the expected incidence of cancer diagnosed during pregnancy as women delay pregnancy to later ages. Of the approximately 110 cancer chemotherapeutic agents currently in use, the NTP monograph includes data on 56 agents used during 1,261 pregnancies for which pregnancy outcomes were documented. Overall, the NTP evaluation found that treatment with chemotherapy for cancer appeared to be associated with: (1) a higher rate of major malformations following exposure during the first trimester compared to exposure in the second and/or third trimester; (2) an increase the rate of stillbirth following exposure in the second and/ or third trimester; abnormally low levels of amniotic fluid (primarily attributable to Trastuzumab); and (3), also data are insufficient, impaired fetal growth and myelosuppression. Treatment with chemotherapy for cancer during pregnancy did not appear to increase spontaneous preterm birth, or impair

Objectives: A cross-sectional study was conducted to evaluate the knowledge and practiced behaviors of gynecologists regarding oral health care during pregnancy and the association of periodontal disease with adverse pregnancy outcomes. Materials and Methods: A questionnaire consisting of 16 questions was designed and pilot tested. One hundred and fifty gynecologists practicing in the private sector of United Arab Emirates (UAE) were approached to voluntarily participate and fill up the questionnaire during February–March 2014. Data retrieved were entered into Excel database and analyzed using SPSS. Results: Of the 150 gynecologists approached, 108 filled the questionnaire, yielding a response rate of 72%. The majority (95.4%) acknowledged a connection between oral health and pregnancy and 75.9% agreed that periodontal disease can affect the outcome of pregnancy. Moreover, most of the gynecologists (85.2%) advised their pregnant patients to visit the dentist during pregnancy. Almost three-quarter of the participants (73%) regarded dental radiographs to be unsafe during pregnancy and more than half (59.3%) considered administration of local anesthesia to be unsafe during pregnancy. Conclusion: The present study demonstrated that gynecologists have a relatively high degree of knowledge with respect to the relationship of periodontal disease to pregnancy outcome. However, there clearly exist misconceptions regarding the provision of dental treatment during pregnancy. To provide better oral health care, more knowledge needs to be made available to the pregnant women and the medical community, and misconceptions regarding the types of dental treatments during pregnancy should be clarified.

Body composition changes in pregnancy: measurement, predictors and outcomes

PubMed Central

Widen, EM; Gallagher, D

2014-01-01

Prevalence of overweight and obesity has risen in the United States over the past few decades. Concurrent with this rise in obesity has been an increase in pregravid body mass index and gestational weight gain affecting maternal body composition changes in pregnancy. During pregnancy, many of the assumptions inherent in body composition estimation are violated, particularly the hydration of fat-free mass, and available methods are unable to disentangle maternal composition from fetus and supporting tissues; therefore, estimates of maternal body composition during pregnancy are prone to error. Here we review commonly used and available methods for assessing body composition changes in pregnancy, including: (1) anthropometry, (2) total body water, (3) densitometry, (4) imaging, (5) dual-energy X-ray absorptiometry, (6) bioelectrical impedance and (7) ultrasound. Several of these methods can measure regional changes in adipose tissue; however, most of these methods provide only whole-body estimates of fat and fat-free mass. Consideration is given to factors that may influence changes in maternal body composition, as well as long-term maternal and offspring outcomes. Finally, we provide recommendations for future research in this area. PMID:24667754

To investigate whether antinuclear autoantibodies (ANA) could be related to the outcome of the successive pregnancy in women with unexplained recurrent miscarriage (uRM). Circulating ANA were measured by indirect immunofluorescence in 86 women with uRM before pregnancy, repeated in the first trimester of the successive gestation and correlated with pregnancy outcome. Forty-one women were ANA- and 45 were ANA+ before pregnancy. No relation was found between pre-pregnancy ANA status and the outcome of the successive pregnancy. However, when these women were monitored at 7th week during their pregnancy for ANA, of the 22 ANA+ women who remained ANA+ seven miscarriages (31.8%) were observed, whereas all of the 23 ANA+ women who became ANA- had pregnancies ongoing beyond the 20th week without miscarriage. ANA status could have a role in uRM. Disappearance of ANA in early pregnancy could have a favorable prognostic value in the successive pregnancy. © 2016 John Wiley & Sons A/S.

Megaw, Lauren, E-mail: lauren.megaw@ed.ac.uk

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 onmore » 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

To determine if persistent ovarian masses in pregnancy are associated with increased adverse outcomes. This is a retrospective cohort of 126 pregnant women with a persistent ovarian mass measuring 5 cm or greater who delivered at two university hospitals between 2001 and 2009. Maternal outcomes included gestational age (GA) at diagnosis, delivery and surgery as well as miscarriage, preterm birth (PTB), ovarian torsion and hospital admission for pain. Neonatal outcomes included birth weight, respiratory distress syndrome (RDS), intra-ventricular hemorrhage (IVH), death and sepsis. A total of 1225 ovarian masses were identified (4.9%) in 24,868 patients. A persistent ovarian mass was found in 0.7%. Average GA at diagnosis was 17.8 weeks. Miscarriage rate was 3.3%. Average GA at delivery was 37.9 weeks. Of the patients, 8.5% had ovarian torsion, 10.3% had admission for pain and 9.3% had PTBs. The mean cesarean delivery rate was 46.3%. The average neonatal weight was 3273 g. There was one neonatal death in this cohort. The rate of RDS was 2.8%, IVH 0.9% and neonatal sepsis 1.9%. The most common surgical pathologic diagnosis was dermoids (37.6%). No overt malignancies were seen. A persistent ovarian mass in pregnancy does not confer an increased risk of adverse pregnancy outcomes.

To determine fertility and pregnancy outcome in women with systemic sclerosis (SSc; scleroderma) who had disease onset before age 45 years. All living women with scleroderma who had first been evaluated at the University of Pittsburgh Scleroderma Clinic after January 1, 1972 were sent a detailed self-administered questionnaire in 1986 specifically concerning pregnancy outcomes and infertility. This group was compared with 2 race- and age-matched control groups, one comprising women with rheumatoid arthritis (RA) and one comprising healthy neighborhood women identified by random-digit dialing. We determined the number, history, treatment, and outcome of women who either had never been pregnant or had attempted to become pregnant unsuccessfully for more than 1 year. We also obtained data regarding pregnancy outcomes, including the frequency of miscarriage, premature births, small full-term infants, perinatal deaths, and births of live healthy infants. The study group comprised 214 women with SSc, 167 with RA, and 105 neighborhood controls. There were no significant differences in the overall rates of miscarriage, premature births, small full-term births, or neonatal deaths between the 3 groups. Women with SSc were more likely than those without SSc to have adverse outcomes of pregnancy after the onset of their rheumatic disease, particularly premature births (also seen in RA women after disease onset) and small full-term infants. Although a significantly greater number of women with SSc had never been pregnant, there were no significant differences in the frequency of never having been pregnant or of infertility in the 3 groups after adjustment for contributing factors. This study indicates that women with SSc have acceptable pregnancy outcomes compared with those of women with other rheumatic disease and healthy neighborhood controls. Infertility was not a frequent problem. We believe that there are no excessive pregnancy risks to women with SSc or their infants

Are women with endometriosis who conceive with IVF at increased risk of preterm birth? Women with endometriosis who conceive with IVF do not face an increased risk of preterm birth. The eutopic endometrium of women with endometriosis has been repeatedly shown to present molecular and cellular alterations. On this basis, it has been hypothesized that pregnancy outcome may be altered in affected women. However, to date, available evidence from epidemiological studies is scanty and conflicting. Data tended to be partly consistent only for an increased risk of preterm birth and placenta previa. Retrospective matched case-control study of women achieving an IVF singleton pregnancy progressing beyond 12 weeks' gestation. Women achieving IVF singleton pregnancies that progressed beyond 12 weeks' gestation at two infertility units were reviewed. Cases were women with a history of surgery for endometriosis and/or with a sonographic diagnosis of the disease at the time of the IVF cycle. Controls were women without current or past evidence of endometriosis who were matched to cases by age (± 6 months), type of cycle (fresh or frozen cycle) and study period. Male factor and unexplained infertility were the most common diagnoses in the control group. Two hundred and thirty-nine women with endometriosis and 239 controls were selected. The main outcome of the study was the rate of preterm birth (birth < 37 weeks' gestation) regardless of the cause. Secondary analyses were performed for the most common obstetrical complications. The rate of preterm birth was similar in the two study groups (14% and 14%, respectively, p = 0.89). The rate of live birth and the incidence of hypertensive disorders, gestational diabetes, small and large for gestational age newborns and neonatal problems also did not differ. In contrast, placenta previa was more common in women with endometriosis than controls (6% versus 1%, respectively; p = 0.006): The adjusted odds ratio was 4.8 (95

Motorized traffic is an important source of both air pollution and community noise. While there is growing evidence for an adverse effect of ambient air pollution on reproductive health, little is known about the association between traffic noise and pregnancy outcomes. We evaluated the impact of residential noise exposure on small size for gestational age, preterm birth, term birth weight, and low birth weight at term in a population-based cohort study, for which we previously reported associations between air pollution and pregnancy outcomes. We also evaluated potential confounding of air pollution effects by noise and vice versa. Linked administrative health data sets were used to identify 68,238 singleton births (1999-2002) in Vancouver, British Columbia, Canada, with complete covariate data (sex, ethnicity, parity, birth month and year, income, and education) and maternal residential history. We estimated exposure to noise with a deterministic model (CadnaA) and exposure to air pollution using temporally adjusted land-use regression models and inverse distance weighting of stationary monitors for the entire pregnancy. Noise exposure was negatively associated with term birth weight (mean difference = -19 [95% confidence interval = -23 to -15] g per 6 dB(A)). In joint air pollution-noise models, associations between noise and term birth weight remained largely unchanged, whereas associations decreased for all air pollutants. Traffic may affect birth weight through exposure to both air pollution and noise.

Evidence that influenza vaccination during pregnancy is safe and effective at preventing influenza disease in women and their children through the first months of life is increasing. Several reports of reduced risk of adverse outcomes associated with influenza vaccination have generated interest in its potential for improving pregnancy outcome. Gavi, the Vaccine Alliance, estimates maternal influenza immunization programs in low-income countries would have a relatively modest impact on mortality compared to other new or under-utilized vaccines, however the impact would be substantially greater if reported vaccine effects on improved pregnancy outcomes were accurate. Here, we examine the available evidence and methodological issues bearing on the relationship between influenza vaccination and pregnancy outcome, particularly preterm birth and fetal growth restriction, and summarize research needs. Evidence for absence of harm associated with vaccination at a point in time is not symmetric with evidence of benefit, given the scenario in which vaccination reduces risk of influenza disease and, in turn, risk of adverse pregnancy outcome. The empirical evidence for vaccination preventing influenza in pregnant women is strong, but the evidence that influenza itself causes adverse pregnancy outcomes is inconsistent and limited in quality. Studies of vaccination and pregnancy outcome have produced mixed evidence of potential benefit but are limited in terms of influenza disease assessment and control of confounding, and their analytic methods often fail to fully address the longitudinal nature of pregnancy and influenza prevalence. We recommend making full use of results of randomized trials, re-analysis of existing observational studies to account for confounding and time-related factors, and quantitative assessment of the potential benefits of vaccination in improving pregnancy outcome, all of which should be informed by the collective engagement of experts in influenza

Objective To characterize the pregnancy outcomes of women Operation Enduring Freedom/Operation Iraqi Freedom (OEF/OIF) Veterans including prevalence of preterm delivery, low birth weight, and macrosomia, and to highlight methodological limitations that can impact findings. Methods A retrospective cohort study was conducted starting in 2014 analyzing data from the 2009 to 2011 National Health Study for a New Generation of US Veterans, which sampled Veterans deployed and not deployed to OIF/OEF. All pregnancies resulting in a live birth were included, and categorized as occurring among non-deployers, before deployment, during deployment, or after deployment. Outcomes included preterm birth, low birth weight, and macrosomia. The association of deployment with selected outcomes was estimated using separate general estimating equations to account for lack of outcome independence among women contributing multiple pregnancies. Adjustment variables included maternal age at outcome, and race/ethnicity. Results There were 2276 live births (191 preterm births, 153 low birth weight infants, and 272 macrosomic infants). Compared with pregnancies before deployment, pregnancies among non-deployers and those after deployment appeared to have greater risk of preterm birth [non-deployers: odds ratio (OR) = 2.16, 95 % confidence interval (CI) 1.25, 3.72; after deployment: OR = 1.90, 95 % CI 0.90, 4.02]. A similar pattern was observed for low birth weight. No association of deployment with macrosomia was detected. Discussion Compared with non-deployers, those who eventually deploy appear to have better pregnancy outcomes prior to deployment, but this advantage is no longer apparent after deployment. Non-deployers may not be an appropriate reference group to study the putative health impacts of deployment on pregnancy outcomes.

Early pregnancy azathioprine use and pregnancy outcomes.

PubMed

Cleary, Brian J; Källén, Bengt

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

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

To provide an integrated review of the literature of potential explanations for better than expected pregnancy outcomes in Mexican immigrants, focusing on socioeconomics, social support, desirability of pregnancy, nutrition, substance use, religion, acculturation, and prenatal care. Computerized searches of MEDLINE and CINAHL databases, as well as reference lists from published articles on low birth weight and prematurity in immigrants and acculturation in immigrants from January 1989 to December 2002. Search terms were Mexican immigrant women, childbearing, and pregnancy outcome, and only English-language articles were reviewed. Literature was selected from refereed publications in the areas of nursing, medicine, public health, family, and sociology. Data were extracted using keywords pertinent to pregnancy outcome in Mexican immigrants. Despite having many of the risk factors for poor pregnancy outcomes, Mexican immigrants have superior birth outcomes when compared to U.S.-born women. Social support, familism, healthy diet, limited use of cigarettes and alcohol, and religion may play a role in improved outcomes. The superior outcomes diminish with the process of acculturation as the individual adapts to her new culture. Low birth weight and prematurity are public health concerns in the United States. Through further study of the factors that lead to superior birth outcomes among Mexican immigrant women, rates of low birth weight and prematurity in the United States may be reduced.

Considering specific physiology changes during gestation and thinking of pregnancy as a "critical window", classification of pregnant women at early pregnancy can be considered as crucial. The paper demonstrates the use of a method based on an approach from intelligent data mining, cluster analysis. Cluster analysis method is a statistical method which makes possible to group individuals based on sets of identifying variables. The method was chosen in order to determine possibility for classification of pregnant women at early pregnancy to analyze unknown correlations between different variables so that the certain outcomes could be predicted. 222 pregnant women from two general obstetric offices' were recruited. The main orient was set on characteristics of these pregnant women: their age, pre-pregnancy body mass index (BMI) and haemoglobin value. Cluster analysis gained a 94.1% classification accuracy rate with three branch- es or groups of pregnant women showing statistically significant correlations with pregnancy outcomes. The results are showing that pregnant women both of older age and higher pre-pregnancy BMI have a significantly higher incidence of delivering baby of higher birth weight but they gain significantly less weight during pregnancy. Their babies are also longer, and these women have significantly higher probability for complications during pregnancy (gestosis) and higher probability of induced or caesarean delivery. We can conclude that the cluster analysis method can appropriately classify pregnant women at early pregnancy to predict certain outcomes.

Childbearing employees are well served by the occupational health nurse who promotes optimal preconceptual and pregnancy health practices, uses community resources, and maintains current knowledge about high risk pregnancy prevention and care. These broad goals of care can lead to decreased absenteeism, healthier and happier employees, and more positive outcomes of pregnancy. For employees with high risk pregnancies, the role of the occupational health nurse includes, but is not limited to, facilitating awareness with the employer, making suggestions for adjusting working conditions, making frequent assessments of the employee's needs, and communicating with prenatal health care providers. Occupational health nurses should never underestimate their role and potential influence on the mother, and on her significant other, for a positive outcome of her pregnancy.

Mast cell-mediated and associated disorders in pregnancy: a risky game with an uncertain outcome?

During pregnancy, the maternal organism is under the influence of tremendous endocrine as well as immunological changes as an adaptation to the implanted and developing fetus. In most cases, the maternal adaptations to pregnancy ensure both, the protection against harmful pathogens and the tolerance toward the growing semi-allogeneic fetus. However, under certain circumstances the unique hormonal milieu during pregnancy is causative of a shift into an unfavorable direction. Of particular importance are cellular disorders previous to pregnancy that involve cell types known for their susceptibility to hormones. One interesting cell type is the mast cell (MC), one of the key figures in allergic disorders. While physiological numbers of MCs were shown to positively influence pregnancy outcome, at least in mouse models, uncontrolled augmentations in quantity, and/or activation can lead to pregnancy complications. Women that have the desire of getting pregnant and been diagnosed with MC mediated disorders such as urticaria and mastocytosis or chronic inflammatory diseases in which MCs are involved, including atopic dermatitis, asthma, or psoriasis, may benefit from specialized medical assistance to ensure a positive pregnancy outcome. In the present review, we address the course of pregnancy in women affected by MC mediated or associated disorders.

To evaluate the complications and outcome of pregnancy in women with polycystic ovary disease (PCOD). The course and outcome of 47 singleton pregnancies in women with well-documented PCOD were compared with those in 100 healthy controls. Women with PCOD had a significantly higher body mass index as compared to the control group (P < .05); however, the proportion of lean versus obese subjects in the two groups was similar. The incidence of an abnormal glucose challenge test, gestational diabetes mellitus and pregnancy-induced hypertension was significantly increased in pregnant women with PCOD (P < .05). When lean PCOD subjects were compared with lean control subjects, the difference in the incidence of the above complications was still significant (P < .05). The incidence of pregnancy complications was similar when obese PCOD subjects were compared with obese controls. Women with PCOD were at increased risk of gestational diabetes and pregnancy-induced hypertension, and this risk appeared to be independent of body mass index.

Pregnancy after bariatric surgery (BS) has an increased risk for small-for-gestational-age infants (SGA), shorter length of gestation, and probably perinatal mortality. The aim of this study was to investigate if biliopancreatic diversion could impair pregnancy outcomes in comparison to other bariatric surgery procedures. We conducted a cohort retrospective single-center study in 65 women before and after BS. Thirty-one pregnancies occurred before BS, while 109 after BS, amongst which n = 51 after biliopancreatic diversion (BPD) and n = 58 after non-malabsorptive procedures. The pregnancy outcomes after BS in comparison with those before BS resulted less affected by diabetes, hypertensive disorders, macrosomia, and large-for-gestational-age (LGA), but more complicated by preterm births (14.5 versus 4.0%) and low birth weight (LBW) infants (28.9 versus 0%). Moreover, mean birth weight resulted lower after BS than before BS (p < 0.001). In pregnancies after BPD in comparison to those before BS, the LBW rate (42.5%) resulted a drastic increase (p < 0.001), and mean birth weight (p < 0.001) and mean birth weight centile (p < 0.001) were lower after BPD. When pregnancy outcomes after BPD were compared with those after non-malabsorptive procedures, the rate of congenital anomalies, preterm births, LBW, and SGA resulted an increase (p = 0.002, 0.008, 0.032, and < 0.001, respectively). BPD drastically reduced diabetes, hypertensive disorders, macrosomia, and LGA; however, it was associated with the poorest pregnancy outcomes in comparison to those observed after other BS procedures. On the basis of the present study, we recommend a cautious multidisciplinary selection of severely obese patients for BPD during the fertile age.

Pregnancy outcomes are affected by many different factors. One of the influential factors on pregnancy outcomes is the male partner as an important person to mother's wellbeing. The aim of the present study was to investigate the effects of male partner's role including socioeconomic support, emotional support, accompanying pregnant women during prenatal care visits (PNC) and labor, and the level of pregnant women's satisfaction from their partners' support and involvement during pregnancy on pregnancy outcomes. Two hundred first gravid pregnant women with mean age of 23.2 ± 4.3 were studied. Primary outcomes were total maternal and neonatal adverse outcome (TMNAO), total maternal adverse end result (TMAE), and total neonatal adverse outcome (TNAO), regardless of the type of outcomes. Preterm labor and delivery; premature rupture of membrane (PROM) and preterm premature rupture of membrane (PPROM); preeclampsia and eclampsia; placental abruption; chorioamnionitis; stillbirth; meconium passage; maternal death; postpartum hemorrhage; poor progression labor; abnormal vaginal bleeding in third trimester of pregnancy; low birth weight and neonatal need for CPR or intubation, neonatal anomaly, NICU admission, and neonatal mortality were also analyzed as subgroup outcomes. 127 (63.5%) participants showed a kind of total maternal and neonatal adverse outcome (TMNAO), 72 (36%) deliveries resulted in a kind of neonatal adverse outcome (TNAO), and 104 (52%) of participants had a kind of maternal adverse end result (TMAE). Iranian fathers showed a significantly higher rate of TMNAO than Afghan fathers did (82 versus 69%, Odd ratio: 2.9, 95% CI 1.0-7.8, P: 0.01). Mother's nationality showed the same result (82 versus 64%, Odd ratio: 2.6, 95% CI 0.9-6.8, P: 0.03). Iranian fathers showed a significantly higher rate of TMAE than Afghan fathers did (79 versus 58%, Odd ratio: 2.7, 95% CI 1.1-6.3, P: 0.01). Mother's nationality showed the same result (78 versus 60%, Odd ratio: 2

Objective. To examine pregnancy and birth outcomes among women with idiopathic thrombocytopenic purpura (ITP) or chronic ITP (cITP) diagnosed before or during pregnancy. Methods. A linkage of mothers and babies within a large US health insurance database that combines enrollment data, pharmacy claims, and medical claims was carried out to identify pregnancies in women with ITP or cITP. Outcomes included preterm birth, elective and spontaneous loss, and major congenital anomalies. Results. Results suggest that women diagnosed with ITP or cITP prior to their estimated date of conception may be at higher risk for stillbirth, fetal loss, and premature delivery. Among 446 pregnancies in women with ITP, 346 resulted in live births. Women with cITP experienced more adverse outcomes than those with a pregnancy-related diagnosis of ITP. Although 7.8% of all live births had major congenital anomalies, the majority were isolated heart defects. Among deliveries in women with cITP, 15.2% of live births were preterm. Conclusions. The results of this study provide further evidence that cause and duration of maternal ITP are important determinants of the outcomes of pregnancy. PMID:27092275

Different etiologies for recurrent pregnancy loss have been identified, among them are: anatomical, endocrine, genetic, chromosomal and thrombophilia pathologies. To assess medical and obstetric characteristics, and pregnancy outcomes, among women with uterine abnormalities and recurrent pregnancy loss (RPL). This study also aims to assess the impact of uterine anatomic surgical correction on pregnancy outcomes. A retrospective case control study of 313 patients with two or more consecutive pregnancy losses followed by a subsequent (index) pregnancy. Anatomic abnormalities were detected in 80 patients. All patients were evaluated and treated in the RPL clinic at Soroka University Medical Center. Out of 80 patients with uterine anatomic abnormalities, 19 underwent surgical correction, 32 did not and 29 had no clear record of surgical intervention, and thus were excluded from this study. Women with anatomic abnormalities had a higher rate of previous cesarean section (18.8% vs. 8.6%, P=0.022), tended to have a lower number of previous live births (1.05 vs. 1.37, P=0.07), and a higher rate of preterm delivery (22.9% vs. 10%, P=0.037). Using multivariate logistic regression analysis, anatomic abnormality was identified as an independent risk factor for RPL in patients with previous cesarean section after controlling for place of residence, positive genetic/autoimmune/endocrine workup, and fertility problems (OR 7.22; 95% CI 1.17-44.54, P=0.03). Women suffering from anatomic abnormalities tended to have a higher rate of pregnancy loss compared to those without anatomic abnormalities (40% vs. 30.9%, P=0.2). The difference in pregnancy loss rate among women who underwent surgical correction compared to those who did not was not statistically significant. In patients with previous cesarean section, uterine abnormality is an independent risk factor for pregnancy loss. Surgical correction of uterine abnormalities among RPL patients might have the potential to improve live

Folic acid: influence on the outcome of pregnancy.

Scholl, T O; Johnson, W G

The periconceptional use of folic acid-containing supplements reduces the first occurrence, as well as the recurrence, of neural tube defects. Women of populations in which adverse pregnancy outcomes are prevalent often consume diets that contain a low density of vitamins and minerals, including folate. Folate intake may need to be sustained after complete closure of the neural tube to decrease the risk of other poor pregnancy outcomes. A central feature of embryonic and fetal development is widespread cell division; folate is central because of its role in nucleic acid synthesis. During gestation, marginal folate nutriture can impair cellular growth and replication in the fetus or placenta. Folate deficiency can occur because dietary folate intake is low or because the metabolic requirement for folate is increased by a particular genetic defect or defects. During pregnancy, low concentrations of dietary and circulating folate are associated with increased risks of preterm delivery, infant low birth weight, and fetal growth retardation. A metabolic effect of folate deficiency is an elevation of blood homocysteine. Likewise, the presence of maternal homocysteine concentrations have been associated both with increased habitual spontaneous abortion and pregnancy complications (eg, placental abruption and preeclampsia), which increase the risk of poor pregnancy outcome and of decreased birth weight and gestation duration.

Sleep duration and disorders in pregnancy: implications for glucose metabolism and pregnancy outcomes

PubMed Central

O’Keeffe, M; St-Onge, M-P

2013-01-01

Humans have an innate requirement for sleep that is intrinsically governed by circadian and endocrine systems. More recently, reduced sleep duration has gained significant attention for its possible contribution to metabolic dysfunction. Significant evidence suggests that reduced sleep duration may elevate the risk for impaired glucose functioning, insulin resistance and type 2 diabetes. However, to date, few studies have determined the implications of reduced sleep duration with regard to glucose control during pregnancy. With the high prevalence of overweight and obesity in women of reproductive age, the occurrence of gestational diabetes mellitus (GDM) is increasing. GDM results in elevated risk of maternal and fetal complications, as well as increased risk of type 2 diabetes postpartum. Infants born to women with GDM also carry a life-long risk of obesity and type 2 diabetes. The impact of reduced sleep on glucose management during pregnancy has not yet been fully assessed and a paucity of literature currently exits. Herein, we review the association between reduced sleep and impaired carbohydrate metabolism and propose how reduced sleep during pregnancy may result in further dysfunction of the carbohydrate axis. A particular focus will be given to sleep-disordered breathing, as well as GDM-complicated pregnancies. Putative mechanisms of action by which reduced sleep may adversely affect maternal and infant outcomes are also discussed. Finally, we will outline important research questions that need to be addressed. PMID:22945608

During pregnancy, fetal growth causes an increase in the total number of rapidly dividing cells, which leads to increased requirements for folate. Inadequate folate intake leads to a decrease in serum folate concentration, resulting in a decrease in erythrocyte folate concentration, a rise in homocysteine concentration, and megaloblastic changes in the bone marrow and other tissues with rapidly dividing cells To assess the effectiveness of oral folic acid supplementation alone or with other micronutrients versus no folic acid (placebo or same micronutrients but no folic acid) during pregnancy on haematological and biochemical parameters during pregnancy and on pregnancy outcomes. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (31 December 2012) and we contacted major organisations working in micronutrient supplementation, including UNICEF Nutrition Section, World Health Organization (WHO) Maternal and Reproductive Health, WHO Nutrition Division, and National Center on Birth defects and Developmnetal Disabilities, US Centers for Disease Control and Prevention (CDC). All randomised, cluster-randomised and cross-over controlled trials evaluating supplementation of folic acid alone or with other micronutrients versus no folic acid (placebo or same micronutrients but no folic acid) in pregnancy. Two review authors independently assessed trials for inclusion, assessed risk of bias and extracted data. Data were checked for accuracy. Thirty-one trials involving 17,771 women are included in this review. This review found that folic acid supplementation has no impact on pregnancy outcomes such as preterm birth (risk ratio (RR) 1.01, 95% confidence interval (CI) 0.73 to 1.38; three studies, 2959 participants), and stillbirths/neonatal deaths (RR 1.33, 95% CI 0.96 to 1.85; three studies, 3110 participants). However, improvements were seen in the mean birthweight (mean difference (MD) 135.75, 95% CI 47.85 to 223.68). On the other hand, the review

The study was designed to assess the views and knowledge of healthcare providers in general medicine and other specialties on the association between oral health and pregnancy outcomes. Two hundred and fifty physicians practicing in northern Jordan hospitals and healthcare centers were asked to complete a questionnaire. Completed questionnaires with the answers were returned completed by 197 participants (response rate was 79%). The majority of the physicians (81%) agreed that pregnancy increases the tendency to have gingival inflammation. However, 88% of doctors advised delay dental treatment until after pregnancy. Only half (54%) thought that tooth and gums problem can affect the outcomes of pregnancy. Moreover, approximately 50% agreed with the possible association between oral health and pregnancy outcomes. Altogether, 52% agreed with the statement 'a tooth for a baby' and 57% believed that calcium will be drawn by the developing baby. If asked to advise patient to visit dentist during pregnancy, 50% said they would do so. Moreover, the majority (68%) did not advise women planning to become pregnant to include a periodontal evaluation as part of their prenatal care. About 32% felt that periodontal disease can be treated safely during pregnancy with a procedure called scaling and root planning. Reading the information in a book, magazine or pamphlet was useful and reliable information about preterm births and periodontal disease. Physicians do not routinely advise their patient to seek dental care during pregnancy. General practitioners were less informed about oral health practices on pregnant women. Issues on training need to be addressed. A public health campaign is required to educate healthcare providers to encourage pregnant women on the need for a regular dental check-up during and prior to attempting pregnancy. There is a need to educate healthcare personnel further about oral health and pregnancy outcomes.

OBJECTIVE To estimate whether elevations of complement C3a early in pregnancy are predictive of the subsequent development of adverse pregnancy outcomes. METHODS A plasma sample was obtained from each enrolled pregnant woman before 20 weeks of gestation. The cohort (n=1,002) was evaluated for the development of adverse pregnancy outcomes defined as hypertensive diseases of pregnancy (gestational hypertension or preeclampsia), preterm birth (before 37 weeks of gestation), premature rupture of the membranes, pregnancy loss (during the embryonic and fetal period), intrauterine growth restriction, and the composite outcome of any adverse outcome. RESULTS One or more adverse pregnancy outcomes occurred in 211 (21%) of the cohort. The mean levels (ng/mL) of C3a in early pregnancy were significantly (P=<.001) higher among women with one or more adverse outcomes (858±435) compared with women with an uncomplicated pregnancy (741±407). Adjusted for parity and prepregnancy body mass index, women with levels of C3a in the upper quartile in early pregnancy were three times more likely to have an adverse outcome later in pregnancy compared with women in the lowest quartile (95% confidence interval, 1.8–4.8; P<.001). The link between early elevated C3a levels and adverse pregnancy outcomes was driven primarily by individual significant (P<.05) associations of C3a with hypertensive diseases of pregnancy, preterm birth, and premature rupture of the membranes. CONCLUSION Elevated C3a as early as the first trimester of pregnancy is an independent predictive factor for adverse pregnancy outcomes, suggesting that complement-related inflammatory events in pregnancy contribute to the subsequent development of poor outcomes at later stages of pregnancy.

We evaluated the potential and the validity of the Quebec Pregnancy Cohort (QPC) as a research tool in perinatal pharmacoepidemiology. The QPC was built by linking four administrative databases: RAMQ (medical and pharmaceutical data), Med-Echo (hospitalizations), ISQ (births/deaths), and MELS (Ministry of Education data). A self-administered questionnaire was sent to a random sample of women to collect lifestyle information. The QPC includes data on all pregnancies of women covered by the Quebec provincial prescription drug insurance between 1998 and 2008. Date of entry in the QPC is the first day of pregnancy, and women are followed during and after pregnancy; children are followed after birth up until 2009. The prevalence of prescribed medications before, during and after pregnancy was compared between time-window. Pregnancy outcomes were also estimated among pregnancies ending with a live born infant. The QPC included 289,688 pregnancies of 186,165 women. Among them, 167,398 ended with a delivery representing 19.4% of all deliveries occurring in the Province of Quebec between 1998-2009. The total frequency of abortions was 35.9% in the QPC comparable to the 36.4% observed in the Province of Quebec. The prevalence of prescribed medication use was 74.6%, 59.0%, and 79.6% before, during and after pregnancy, respectively. Although there was a statistically significant decrease in the proportion of use once the pregnancy was diagnosed (p<.01), post-pregnancy prescribed medication use returned above the pre-pregnancy level. The prevalence of pregnancy outcomes found in the QPC were similar to those observed in the Province of Quebec. The QPC is an excellent tool for the study of the risk and benefit of drug use during the perinatal period. This cohort has the advantage of including a validated date of beginning of pregnancy giving the possibility of assigning the exact gestational age at the time of maternal exposure.

Isotretinoin, a teratogen, is widely used to treat cystic acne. Although the risks of pregnancy during isotretinoin therapy are well recognized, there are doubts about the level of adherence with the pregnancy prevention program in Canada. Our objective was to evaluate the effectiveness of the Canadian pregnancy prevention program in 4 provinces: British Columbia, Saskatchewan, Manitoba and Ontario. Using administrative data, we identified 4 historical cohorts of female users of isotretinoin (aged 12-48 yr) for the period 1996 to 2011. We defined pregnancy using International Statistical Classification of Diseases and billing codes. One definition included only cases with documented pregnancy outcomes (high-specificity definition); the other definition also included individuals recorded as receiving prenatal care (high-sensitivity definition). We studied new courses of isotretinoin and detected pregnancies in 2 time windows: during isotretinoin treatment only and up to 42 weeks after treatment. Live births were followed for 1 year to identify congenital malformations. A total of 59 271 female patients received 102 308 courses of isotretinoin. Between 24.3% and 32.9% of participants received prescriptions for oral contraceptives while they were taking isotretinoin, compared with 28.3% to 35.9% in the 12 months before isotretinoin was started. According to the high-specificity definition of pregnancy, there were 186 pregnancies during isotretinoin treatment (3.1/1000 isotretinoin users), compared with 367 (6.2/1000 users) according to the high-sensitivity definition. By 42 weeks after treatment, there were 1473 pregnancies (24.9/1000 users), according to the high-specificity definition. Of these, 1331 (90.4%) terminated spontaneously or were terminated by medical intervention. Among the 118 live births were 11 (9.3%) cases of congenital malformation. Pregnancy rates during isotretinoin treatment remained constant between 1996 and 2011. Adherence to the isotretinoin

To report the obstetrical outcomes in patients with twin pregnancies who underwent an emergency/physical exam-indicated cerclage and to compare them to patients with singleton pregnancies undergoing the same procedure. Patients who underwent emergency/physical exam-indicated cerclage in the second trimester in one maternal-fetal medicine practice from July 1997 to March 2012 were reviewed. We defined an emergency/physical exam-indicated cerclage as any cerclage placed in a patient with a dilated cervix on examination or membranes visible at the external cervical os on speculum examination. We compared outcomes between patients with singleton and twin pregnancies using non-parametric testing. There were 43 patients (12 twin and 31 singleton pregnancies) who underwent emergency/physical exam-indicated cerclage placement. The median gestational age at cerclage placement, cervical dilation, maternal age, and cerclage type were similar between the groups. Comparing twins to singletons, the median time from cerclage placement to delivery was similar (92 vs. 106 days, p=0.330), as was the median gestational age at delivery (33.5 vs. 35.0 weeks, p=0.244). The likelihood of delivery at >32 weeks (75.0% vs. 71.0%, p>0.999) and the likelihood of neonatal survival to discharge (83.3% vs. 83.9%, p>0.999) were also similar. Emergency/physical exam-indicated cerclage in twin pregnancies can be associated with favorable outcomes, including a high likelihood of delivery at >32 weeks and a high likelihood of survival. Their outcomes appear similar to singleton pregnancies. Cerclage should be considered an option for patients with twin pregnancies and a dilated cervix in the second trimester.

This is a descriptive and cross-sectional study aiming to determine the factors affecting sexual life in pregnant women. The study was carried out in 238 women in Malatya, Turkey. It was found that 61.4% regarded coitus as a risk during pregnancy, 31.9% did not have any knowledge about this matter. In 81.5% sexual life was affected during pregnancy. The mean frequency of intercourse was 2.02 +/- 0.7/week before pregnancy and decreased to 1.51 +/- 0.6/week during pregnancy. The reasons for this decline are: exhaustion and fatigue (64.3%); waning of sexual desire (55.9%); harmful to the fetus (49.2%); causing abortions in early pregnancy (45%), and inducing preterm labor (34%). There was a significant relationship between changes in sexual life during pregnancy and the duration of marriage (chi2=10.8, p<0.05), education level (chi2=18.1, p<0.05), parity (chi2=11.1, p<0.05), and gravidity (chi2=6.8, p<0.05). The variables such as age, employment status, and number of abortions did not affect sexual life during pregnancy. Copyright 2004 S. Karger AG, Basel

To examine risk factors, treatment, and outcomes for nausea/vomiting (N/V) and heartburn during pregnancy. We included 2731 women from a prospective cohort study of gallbladder disease in pregnancy. Subjects completed questionnaires at enrollment, early third trimester, and 4-6 weeks postpartum. We used logistic regression to examine independent predictors of upper gastrointestinal symptoms. Ninety-five percent of pregnant women experienced either heartburn and/or N/V. Independent predictors for heartburn included prepregnancy heartburn (OR 5.28, 95% CI 3.78-7.37), multigravidity, prepregnancy body mass index, and pregnancy weight gain. Independent predictors for N/V included prepregnancy N/V (OR 2.25, 95% CI 1.52-3.31), other digestive problems prepregnancy, younger age, single gestation, and carrying a female fetus. 11% of women with N/V and 47% of women with heartburn used pharmacologic therapy. Infants born to women with heartburn had significantly higher birth weights (p = 0.03), but gestational age at delivery was not significantly different. N/V was not associated with birth weight or gestational age at delivery. 19.7% of women with heartburn during pregnancy reported postpartum heartburn. Heartburn and N/V are common pregnancy symptoms, particularly among women with a history of such symptoms. Neither condition appears to adversely affect the outcome of pregnancy. Pregnancy-related heartburn predisposes to early postpartum heartburn.

We performed a retrospective cohort study of 3530 women treated for cervical intraepithelial neoplasia (CIN) in Helsinki University Central Hospital, Finland, to investigate whether CIN treatment itself affects pregnancy incidence and outcome. We estimated the incidence of live births, miscarriages, extrauterine pregnancies, molar pregnancies, and termination of pregnancies (TOPs) before and after CIN treatment using nationwide registers. Women were followed up until death, emigration, sterilization, or the end of 2004. The comparison of incidence of pregnancy outcomes before and after the treatment was estimated by calculating hazard ratios (HRs) with conditional Poisson regression. After 76,162 woman-years of follow-up, the incidence of any pregnancy remained constant over CIN-treatment, HR 1.02 and 95% confidence interval (CI) 0.97–1.08, but the incidence of the first pregnancy was significantly elevated after treatment, HR 1.13, and 95% CI 1.03–1.23. The incidence of live births was significantly elevated after treatment, HR 1.08 and 95% CI 1.01–1.15. Incidence of miscarriages, TOPs, extrauterine pregnancies, and molar pregnancies was not elevated. TOPs was significantly increased in the first pregnancy, HR 1.40, 95% CI 1.15–1.72 and after treatment by the loop electrosurgical excision procedure (LEEP), HR 1.36, 95% CI 1.15–1.60. CIN treatment did not reduce pregnancy incidence and women had more live births after than before CIN treatment. TOPs was more common in the first pregnancy or after treatment by LEEP. We encourage research on the psychosocial consequences of CIN treatment also in other countries and settings. PMID:25146172

Background: Trace elements and specially minerals are critical for the development of fetus. Many minerals are transferred to the fetus for fetal stores in the latter part of the pregnancy. It has been shown that various trace elements such as Zinc, Iron, Calcium and Magnesium are metabolically interrelated and there is alteration in their concentration during pregnancy. Beyond pregnancy is associated with increased demand of all the nutrients and deficiency of any of these could affect pregnancy, delivery and outcome of pregnancy. Aim: To study the levels of trace elements namely zinc, iron, magnesium and calcium in maternal and umbilical cord blood and their association with pregnancy outcome. Methods: Sixty pregnant women in Zabol, Iran were selected from those who had registered their names for the prenatal care and who had followed up till the 3rd trimester of pregnancy ending in child birth. Biochemical parameters analyzed with help of the biochemical laboratory. Data were analyzed by SPSS software. Results: The mean biochemical profile such, serum calcium, magnesium, zinc and iron in the pregnant women were as follow: in the 1st trimester 8.3, 1.9, 74.9 and 74.4 µg/dl respectively; in the 2nd trimester 8.5, 1.9, 73.1 and 79.3 µg/dl, respectively; in the 3rd trimester 8.6, 1.9, 68.4, and 82.2 µg/dl, respectively. In the umbilical cord blood, the mean serum calcium, magnesium, zinc and iron were 8.5, 1.9, 84.1, and 89.8 µg/dl, respectively. The mean serum calcium and magnesium during the three trimesters of pregnancy were not significantly different from that in the umbilical cord blood, while the mean serum zinc and iron in the umbilical cord blood were significantly different (p<0.05) in the three trimester of pregnancy. The mean birth weight of neonates was 3.1 kg and 12% of neonates showed low birth weight. Our findings showed that, except magnesium, the profile of other biochemical variables, namely, calcium, zinc and iron in the umbilical cord blood

To investigate the severe adverse pregnancy outcomes in pregnancies with placenta previa and prior cesarean delivery and its risk factors. This retrospective casecontrol study reviewed all pregnancies with placenta previa and prior cesarean delivery delivered by repeat cesarean section in our institution between January 2005 and June 2015,and investigated the incidence of severe adverse pregnancy outcome. A composite of severe adverse pregnancy outcomes (including transfusion of 10 units or more red blood cells,maternal ICU admission,unanticipated injuries,repeat operation,hysterectomy,and maternal death) and other maternal and neonatal outcomes were described. Univariate and multivariable logistic regression analysis were used to quantify the effects of risk factors on severe adverse pregnancy outcomes. There were 478 women with placenta previa and prior cesarean delivery in our hospital over the last decade. The average age of them was 32.5±4.8 years old,most women were beyond 30 years old,the average gravidity and parity were 4 and 1,131 cases (27.4%) had severe adverse pregnancy outcomes. Transfusion of 10 units or more red blood cells happened in 75 cases (15.7%,75/478); 44 cases (9.2%,44/478) necessitated maternal ICU admission; unanticipated bladder injury occurred in 11 cases,but non ureter or bowel injury happened; All 4 repeat operations were due to delayed hemorrhage after conservative management during cesarean delivery,and an emergent hysterectomy was performed for all of the 4 cases. Hysterectomy (107 cases,22.4%) was the most common severe adverse pregnancy outcome. Among all 311 morbidly adherent placenta cases finally confirmed by pathological or surgical findings or both,only 172 (55.3%) were suspected before delivery. Multivariable logistic regression analysis showed that the risk of severe adverse pregnancy outcomes was significantly increased by pernicious placenta previa (i.e. anterior placenta overlying the prior cesarean scar),suspicion of

The present study aims to determine the association of periodontal disease (identified early in pregnancy) and adverse pregnancy outcomes in a North Indian population.   A total of 340 primigravida women, aged 20-35 years with single live pregnancy were recruited at 14-20 weeks period of gestation from the antenatal clinic. These women had undergone periodontal examination at time of recruitment. The pregnancy outcomes were recorded. Out of 340 primigravida women, 147 (43.23%) women had gingivitis and 61 (17.94%) women had periodontitis. Periodontitis was found to be significantly associated with pre-eclampsia, intrauterine growth restriction, preterm delivery, and low birthweight with odds ratios (95% confidence interval) of 7.48 (2.72-22.42), 3.35 (1.20-9.55), 2.72 (1.30-5.68) and 3.03 (1.53-5.97), respectively. The study shows a significant association between periodontitis (but not with gingivitis) and adverse pregnancy outcomes. Maternal periodontitis is associated with an increased risk of pre-eclampsia, intrauterine growth restriction, preterm delivery and low birthweight infants. © 2012 The Authors.

To evaluate pregnancy outcomes in women with liver cirrhosis, portal hypertension, or esophageal varices. We analyzed a retrospective cohort of 2,284,218 pregnancies in 2005-2009 recorded in the California Birth Registry database. Utilizing ICD-9 codes we analyzed the following outcomes for liver cirrhosis, portal hypertension, or esophageal varices in pregnancy: preeclampsia (PET), preterm delivery (PTD; <37 weeks), cesarean section, low birth weight (LBW; <2500 g), small for gestational age (SGA; <10th percentile), neonatal death (NND), and postpartum hemorrhage (PPH). Cirrhosis in pregnancy conferred an increased risk of PET, PTD, CS in multiparous women, LBW, and NND. Portal hypertension in pregnancy was associated with PTD, LBW, NND, and PPH. Non-bleeding esophageal varices in pregnancy were not associated with the outcomes assessed in a statistically significant manner. One case of bleeding esophageal varices was observed, resulting in PTD with a LBW infant. There were three cases of concomitant portal hypertension or concomitant esophageal varices with cirrhosis in pregnancy. Pregnancy in women with concomitant liver cirrhosis, portal hypertension, or esophageal varices can be successful. However, pregnancy outcomes are worse and may warrant closer antenatal monitoring and patient counseling. Cirrhosis in pregnancy with concomitant portal hypertension or esophageal varices is rare.

To examine the effect of obesity on maternal and neonatal outcomes in women diagnosed with gestational diabetes mellitus (GDM) and managed with diet only, glyburide, or insulin. Women with singleton gestations enrolled for outpatient services diagnosed with GDM and without history of pregnancy-related hypertension at enrollment or in a prior pregnancy were identified in a database. Women with GDM controlled by diet only (n = 3918), glyburide (n = 873), or insulin without prior exposure to oral hypoglycemic agents (n = 2229) were included. Pregnancy outcomes were compared for obese versus nonobese women within each treatment group and also compared across treatment groups within the obese and nonobese populations. Within each treatment group, obesity was associated with higher rates of cesarean delivery, pregnancy-related hypertension, macrosomia, and hyperbilirubinemia (all p < 0.05). Higher rates of pregnancy-related hypertension and hyperbilirubinemia were observed in women receiving glyburide. Obesity adversely affects pregnancy outcome in women with GDM. Higher rates of pregnancy-related hypertension and hyperbilirubinemia were observed in pregnant women receiving glyburide. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

In India, the prevalence of low birth weight is high in women with a low body mass index (BMI), suggesting that underweight women are not capable of providing adequate energy and protein for fetal growth. Furthermore, as pregnancy progresses, there is increased need to provide methyl groups for methylation reactions associated with the synthesis of new proteins and, unlike normal-BMI American women, low-BMI Indian women are unable to increase methionine transmethylation and remethylation rates as pregnancy progresses from trimester 1 to 3. This also negatively influences birth weight. The aim was to determine the effect of dietary supplementation with energy and protein from 12 ± 1 wk of gestation to time of delivery compared with no supplement on pregnancy outcomes, protein kinetics, and the fluxes of the methyl group donors serine and glycine. Protein kinetics and serine and glycine fluxes were measured by using standard stable isotope tracer methods in the fasting and postprandial states in 24 pregnant women aged 22.9 ± 0.7 y with low BMIs [BMI (in kg/m(2)) ≤18.5] at 12 ± 1 wk (trimester 1) and 30 ± 1 wk (trimester 3) of gestation. After the first measurement, subjects were randomly assigned to either receive the supplement (300 kcal/d, 15 g protein/d) or no supplement. Supplementation had no significant effect on any variable of pregnancy outcome, and except for fasting state decreases in leucine flux (125 ± 7.14 compared with 113 ± 5.06 μmol ⋅ kg(-1) ⋅ h(-1); P = 0.04) and nonoxidative disposal (110 ± 6.97 compared with 101 ± 3.69 μmol ⋅ kg(-1) ⋅ h(-1); P = 0.02) from trimesters 1 to 3, it had no effect on any other leucine kinetic variable or urea, glycine, and serine fluxes. We conclude that in Indian women with a low BMI, supplementation with energy and protein from week 12 of pregnancy to time of delivery does not improve pregnancy outcome, whole-body protein kinetics, or serine and glycine fluxes. © 2016 American Society for Nutrition.

Background Violence against pregnant women is an increasing public health concern particularly in low- and middle-income countries. The purpose of this study was to measure the association between intimate partner violence (IPV) during pregnancy and the risk of adverse birth outcomes. Methods Prospective cohort study of 1276 pregnant women in Dong Anh district, Vietnam. Women with gestational age less than 24 weeks were enrolled and interviewed. Repeated interviews were performed at 30–34 weeks gestation to assess experience of IPV during pregnancy and again 48 hours post-delivery to assess the birth outcome including birth weight and gestational age at delivery. Results There was a statistically significant association between exposure to physical violence during pregnancy and preterm birth (PTB) or low birth weight (LBW). After adjustment for age, education, occupation, body mass index (BMI), haemoglobin level, previous adverse pregnancy outcomes, the pregnant women who were exposed to physical violence during pregnancy were five times more likely to have PTB (AOR = 5.5; 95%CI: 2.1–14.1) and were nearly six times more likely to give birth to a child of LBW (AOR = 5.7; 95%CI: 2.2–14.9) as compared to those who were not exposed to physical violence. Conclusion Exposure to IPV during pregnancy increases the risk of PTB and LBW. Case-finding for violence in relation to antenatal care may help protect pregnant women and improve pregnancy outcomes.

Presently, the matter of pregnancy outcomes of patients with pregnancy related AKI (PR-AKI) were disputed. Thus, we conducted a meta-analysis to evaluate the impact of PR-AKI on pregnancy outcomes. We systematically searched MEDLINE, Embase, VIP, CNKI and Wanfang Databases for cohort or case-control studies in women with PR-AKI and those without AKI as a control group to assess the influence of PR-AKI on pregnancy outcomes and kidney outcome. Reduction of odd ratio (OR) was calculated by a random-effects model. One thousand one hundred fifty two articles were systematically reviewed, of those 11 studies were included, providing data of 845 pregnancies in 834 women with PR-AKI and 5387 pregnancies in 5334 women without AKI. In terms of maternal outcomes, women with PR-AKI had a greater likelihood of cesarean delivery (OR, 1.49; 95% confidence interval [CI], 1.37 to 1.61), hemorrhage (1.26; 1.02 to 1.56), HELLP syndrome (1.86; 1.41 to 2.46), placental abruption (3.13; 1.96 to 5.02), DIC (3.41; 2.00 to 5.84), maternal death (4.50; 2.73 to 7.43), but had a lower risk of eclampsia (0.53; 0.34 to 0.83). Women with PR-AKI also had a longer stay in ICU (weighted mean difference, 2.13 day [95% CI 1.43 to 2.83 day]) compared with those without PR-AKI. As for fetal outcomes, higher incidence of stillbirth/perinatal death (3.39, 2.76 to 4.18), lower mean gestational age at delivery (-0.70 week [95% CI -1.21 to -0.19 week]) and lower birth weight (-740 g [95% CI -1180 to 310 g]) were observed in women with PR-AKI. The occurrence of kidney outcome, defined as ESRD requiring dialysis, in women with PR-AKI was 2.4% (95% CI 1.3% to 4.2%). PR-AKI remains a grave complication and has been associated with increased maternal and fetal mortality.

Observed adverse effects of antiretroviral therapy (ART) on the lipid profile could be of significance in pregnancy. This systematic review aims to summarize studies that investigated the association between HIV, ART and serum lipids during pregnancy and adverse pregnancy outcomes. A systematic search was conducted in five electronic databases to obtain articles that measured serum lipid concentrations or the incidence of dyslipidaemia in HIV-infected pregnant women. Included articles were assessed for quality according to the Cochrane Risk of Bias Tool. The extracted data was analysed through descriptive analysis. Of the 1264 articles screened, 17 articles were included in this review; eleven reported the incidence of dyslipidaemia, and twelve on maternal serum lipid concentrations under the influence of HIV-infection and ART. No articles reported pregnancy outcomes in relation to serum lipids. Articles were of acceptable quality, but heterogenic in methods and study design. Lipid levels in HIV-infected women increased 1.5-3 fold over the trimesters of pregnancy, and remained within the physiological reference range. The percentage of women with dyslipidaemia was variable between the studies [0-88.9%] and highest in the groups on first generation protease inhibitors and for women on ART at conception. This systematic review observed physiologic concentrations of serum lipids for HIV-infected women receiving ART during pregnancy. Serum lipids were increased in users of first generation protease inhibitors and for those on treatment at conception. There was no information available about pregnancy outcomes. Future studies are needed which include HIV-uninfected control groups, control for potential confounders, and overcome limitations associated with included studies.

Purpose We evaluated the potential and the validity of the Quebec Pregnancy Cohort (QPC) as a research tool in perinatal pharmacoepidemiology. Methods The QPC was built by linking four administrative databases: RAMQ (medical and pharmaceutical data), Med-Echo (hospitalizations), ISQ (births/deaths), and MELS (Ministry of Education data). A self-administered questionnaire was sent to a random sample of women to collect lifestyle information. The QPC includes data on all pregnancies of women covered by the Quebec provincial prescription drug insurance between 1998 and 2008. Date of entry in the QPC is the first day of pregnancy, and women are followed during and after pregnancy; children are followed after birth up until 2009. The prevalence of prescribed medications before, during and after pregnancy was compared between time-window. Pregnancy outcomes were also estimated among pregnancies ending with a live born infant. Results The QPC included 289,688 pregnancies of 186,165 women. Among them, 167,398 ended with a delivery representing 19.4% of all deliveries occurring in the Province of Quebec between 1998–2009. The total frequency of abortions was 35.9% in the QPC comparable to the 36.4% observed in the Province of Quebec. The prevalence of prescribed medication use was 74.6%, 59.0%, and 79.6% before, during and after pregnancy, respectively. Although there was a statistically significant decrease in the proportion of use once the pregnancy was diagnosed (p<.01), post-pregnancy prescribed medication use returned above the pre-pregnancy level. The prevalence of pregnancy outcomes found in the QPC were similar to those observed in the Province of Quebec. Conclusion The QPC is an excellent tool for the study of the risk and benefit of drug use during the perinatal period. This cohort has the advantage of including a validated date of beginning of pregnancy giving the possibility of assigning the exact gestational age at the time of maternal exposure. PMID:24705674

To identify risk factors associated with velamentous cord insertion (VCI) and to evaluate the association between adverse pregnancy outcomes and VCI in singleton pregnancies. The total population of women (n=26,849) with singleton pregnancies delivered in Kuopio University Hospital during the study period between 2000 and 2011 was reviewed. Risk factors and the risk of adverse pregnancy outcomes (admission to a neonatal unit, fetal death, preterm delivery, low birth weight (LBW< 2500 g), the infant being small for its gestation age (SGA), low Apgar scores (<7) at 1 and 5 min and fetal venous pH<7.15) were evaluated separately among women with and without VCI by means of logistic regression analyses. The incidence of VCI among women with singleton pregnancies was 2.4% (n=633 of 26,849). Independent risk factors for VCI were nulliparity, obesity, fertility problems, placenta previa and maternal smoking. VCI was associated with a 1.38-, 2.01-, 3.93- and 1.39-fold increased risk of admission to a neonatal unit, preterm delivery (<37 gestation weeks), LBW and SGA, respectively compared to pregnancies involving normal cord insertion. Of the women with VCI, 15.3% underwent non-elective cesarean section compared to 8.3% (p ≤ 0.001) of women without VCI. The results suggest that the incidence of VCI increases along with an increase in fertility problems and maternal obesity. VCI is a moderate risk condition increasing the risks of prematurity and impaired fetal growth. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

The incidence of Bell's palsy (BP) is elevated in the late phases of pregnancy. Controversy exists as to whether pregnancy is a risk factor for worse outcomes in BP, and whether such outcomes are the result of factors intrinsic to pregnancy or the tendency to withhold medical therapy in this cohort. Long-term facial function outcomes in cases of pregnancy-associated BP (PABP) were compared against outcomes in cases affecting nonpregnant adult women of child-bearing age by a blinded expert using the electronic clinician-graded facial function scale (eFACE) facial grading system. Fifty-one pregnancy-associated cases and 58 nonpregnancy-associated cases were included. Among patients who received early corticosteroid therapy, significantly worse static, synkinesis, and composite facial function eFACE scores were demonstrated among cases of PABP compared to nonpregnancy-associated cases (static median = 86 vs. 92.5, P = 0.005; synkinesis median = 79 vs. 86, P = 0.007; composite median = 78 vs. 84, P = 0.023). Among those not treated with corticosteroids, significantly worse dynamic and composite facial function eFACE scores were demonstrated in cases of PABP compared to those for nonpregnancy-associated cases (dynamic median = 74 vs. 92.5, P = 0.038; composite median = 73 vs. 86.5, P = 0.038). A trend toward improved outcomes was demonstrated within both groups for those treated with corticosteroids compared to those who were not. In comparison to cases unrelated to pregnancy, late-term PABP is associated with worse long-term outcomes to a degree that cannot solely be explained by differences in medical therapy. 4.

To identify key factors implicated in adverse perinatal outcome in monochorionic twin pregnancies complicated by selective fetal growth restriction. This is a retrospective cohort study conducted in a single tertiary referral centre included all monochorionic diamniotic (MCDA) twin pregnancies complicated by selective fetal growth restriction (sFGR). The presence of co-existing twin to twin transfusion syndrome (TTTS) was noted. Fetal biometry and Doppler indices, including the umbilical artery (UA) and ductus venosus (DV), were recorded at the time of diagnosis. The type of sFGR was diagnosed according to the pattern of end-diastolic flow (EDF) in the UA of the smaller twin. DV pulsatility indices were converted to z-scores and estimated fetal weight (EFW) values to centiles, to correct for gestational age (GA). Cox proportional hazards model was used to examine for independent predictors of adverse perinatal outcome. Adverse perinatal outcome was defined according to survival and included both intra-uterine fetal demise and neonatal death of the FGR twin. We analysed 104 pregnancies complicated by sFGR. Sixty-six (63.5%) were diagnosed with type I and 38 (36.5%) with type II at initial presentation. Pregnancies complicated by type II sFGR were diagnosed (median GA 19.6 weeks' vs 21.5 weeks, p=0.012) and delivered (median GA 30.4 weeks' vs 32.57 weeks; p=0.055) earlier and are associated with increased risk of adverse perinatal outcomes (intrauterine demise of the smaller twin 19.7% vs 10.6%, p=0.001), when compared to type I sFGR. Twin pregnancies complicated by sFGR, whether type I or II, resulting in intrauterine demise have a significantly earlier onset of diagnosis (p<0.001), earlier GA at delivery (p<0.05), higher DV pulsatility index (p<0.05), and lower birth weight (BW) centile of the smaller twin (p<0.01) when compared to pregnancies resulting in livebirth. Co-existing TTTS had no significant impact on the perinatal outcome of pregnancies diagnosed with

Vedolizumab is a gut-selective immunoglobulin G 1 monoclonal antibody to α 4 β 7 integrin for the treatment of Crohn's disease (CD) and ulcerative colitis (UC). Prospective clinical studies of vedolizumab in pregnancy have not been conducted; therefore, existing safety data of vedolizumab in pregnancy were examined. To assess pregnancy outcomes in females and partners of males who received vedolizumab. All pregnancy data collected during the clinical programme (from 14 May 2007 to 27 June 2013) and in the post-marketing setting (to 19 November 2015) were analysed. Across six studies, there were 27 pregnancies in female participants and 19 pregnancies in partners of male participants. Among 24 vedolizumab-treated females (23 with CD/UC, one healthy volunteer), there were 11 live births, five elective terminations, four spontaneous abortions and four undocumented outcomes. A congenital corpus callosum agenesis anomaly was reported in one live birth from a healthy volunteer with extensive obstetric history exposed to single-dose vedolizumab 79 days before estimated conception. Of 19 pregnancies in partners of male participants, there were 11 live births, two spontaneous abortions, three elective terminations and three undocumented outcomes. Post-marketing reports recorded 81 pregnancies, resulting in four live births, 11 spontaneous abortions and 66 pregnancies that were on-going or reported undocumented outcomes. Initial analysis, limited by sample size and follow-up, identified no new safety concerns for pregnancy outcomes in females directly or indirectly exposed to vedolizumab. However, vedolizumab should be used during pregnancy only if the benefits to the mother outweigh the risks to the mother/unborn child. © 2017 John Wiley & Sons Ltd.

Intrauterine hematomas are a common pregnancy complication. The literature lacks studies about outcomes based on hematoma localization. Thus, we aimed to compare pregnancies complicated by an intraplacental hematoma to cases with a retroplacental hematoma and to a control group. In a retrospective case-control study, 32 women with an intraplacental hematoma, 199 women with a retroplacental hematoma, and a control group consisting of 113 age-matched women with no signs of placental abnormalities were included. Main outcome measures were pregnancy complications. Second-trimester miscarriage was most common in the intraplacental hematoma group (9.4%), followed by women with a retroplacental hematoma (4.2%), and controls (0%; p = 0.007). The intraplacental hematoma group revealed the highest rates for placental insufficiency, intrauterine growth retardation, premature preterm rupture of membranes, preterm labor, preterm delivery <37 weeks, and early preterm delivery <34 weeks (p < 0.05), followed by the retroplacental hematoma group. When tested in multivariate models, intraplacental hematomas were independent predictors for placental insufficiency (ß = 4.19, p < 0.001) and intrauterine growth restriction (ß = 1.44, p = 0.035). Intrauterine fetal deaths occurred only in women with a retroplacental hematoma (p = 0.042). Intra- and retroplacental hematomas have different risk profiles for the affected pregnancy and act as independent risk factors.

Pregnancy and Neonatal Diabetes Outcomes in Remote Australia (PANDORA) study

PubMed Central

2013-01-01

Background Diabetes in pregnancy carries an increased risk of adverse pregnancy outcomes for both the mother and foetus, but it also provides an excellent early opportunity for intervention in the life course for both mother and baby. In the context of the escalating epidemic of chronic diseases among Indigenous Australians, it is vital that this risk is reduced as early as possible in the life course of the individual. The aims of the PANDORA Study are to: (i) accurately assess rates of diabetes in pregnancy in the Northern Territory (NT) of Australia, where 38% of babies are born to Indigenous mothers; (ii) assess demographic, clinical, biochemical, anthropometric, socioeconomic and early life development factors that may contribute to key maternal and neonatal birth outcomes associated with diabetes in pregnancy; and (iii) monitor relevant post-partum clinical outcomes for both the mothers and their babies. Methods/Design Eligible participants are all NT women with diabetes in pregnancy aged 16 years and over. Information collected includes: standard antenatal clinical information, diagnosis and management of diabetes in pregnancy, socio-economic status, standard clinical birth information (delivery, gestational age, birth weight, adverse antenatal and birth outcomes). Cord blood is collected at the time of delivery and detailed neonatal anthropometric measurements performed within 72 hours of birth. Information will also be collected regarding maternal post-partum glucose tolerance and cardio-metabolic risk factor status, breastfeeding and growth of the baby up to 2 years post-partum in the first instance. Discussion This study will accurately document rates and outcomes of diabetes in pregnancy in the NT of Australia, including the high-risk Indigenous Australian population. The results of this study should contribute to policy and clinical guidelines with the goal of reducing the future risk of obesity and diabetes in both mothers and their offspring. PMID

The aim of the study was to assess the rate, determinants, and outcomes of repeat pregnancies in women with HIV infection. Data from a national study of pregnant women with HIV infection were used. Main outcomes were preterm delivery, low birth weight, CD4 cell count and HIV plasma viral load. The rate of repeat pregnancy among 3007 women was 16.2%. Women with a repeat pregnancy were on average younger than those with a single pregnancy (median age 30 vs. 33 years, respectively), more recently diagnosed with HIV infection (median time since diagnosis 25 vs. 51 months, respectively), and more frequently of foreign origin [odds ratio (OR) 1.36; 95% confidence interval (CI) 1.10-1.68], diagnosed with HIV infection in the current pregnancy (OR: 1.69; 95% CI: 1.35-2.11), and at their first pregnancy (OR: 1.33; 95% CI: 1.06-1.66). In women with sequential pregnancies, compared with the first pregnancy, several outcomes showed a significant improvement in the second pregnancy, with a higher rate of antiretroviral treatment at conception (39.0 vs. 65.4%, respectively), better median maternal weight at the start of pregnancy (60 vs. 61 kg, respectively), a higher rate of end-of-pregnancy undetectable HIV RNA (60.7 vs. 71.6%, respectively), a higher median birth weight (2815 vs. 2885 g, respectively), lower rates of preterm delivery (23.0 vs. 17.7%, respectively) and of low birth weight (23.4 vs. 15.4%, respectively), and a higher median CD4 cell count (+47 cells/μL), with almost no clinical progression to Centers for Disease Control and Prevention stage C (CDC-C) HIV disease (0.3%). The second pregnancy was significantly more likely to end in voluntary termination than the first pregnancy (11.4 vs. 6.1%, respectively). Younger and foreign women were more likely to have a repeat pregnancy; in women with sequential pregnancies, the second pregnancy was characterized by a significant improvement in several outcomes, suggesting that women with HIV infection who desire multiple

The purpose of this study was to investigate the relationship of selected characteristics of the paternal work environment and occupational history to the incidence of complications in pregnancy, complications in labor and anomalies in birth outcomes. The literature suggested that male exposure to teratogenic hazards in the form of radiation and chemical compounds, primarily in the form of solvents, has been implicated in reproductive disorders and malformed offspring in animals. Similarly, some recent research suggests that the exposure of male workers to such hazards on their job may have consequences for their spouses and children. Based on these experimental researchmore » studies and analyses of persons working in high risk occupations, a broader study of the potential contribution of paternal work environment variables to the success of pregnancy and birth outcomes seemed warranted. Based upon the literature review, a model was proposed for predicting complications in pregnancy, complications in labor and birth outcome (normal birth, low birth weight, congenital malformations and fetal death). From the 1980 National Natality Survey and the 1980 National Fetal Mortality Survey, four sub-samples of married couples, with both husband and wife employed, were selected on the basis of one of the four birth outcomes. The model called for controlling a range of maternal intrinsic and extrinsic health and behavioral variables known to be related to birth outcomes. Multiple logistic regression procedures were used to analyze the effects of father's exposure to radiation and solvents on the job, to complications in pregnancy and labor, and to birth outcome, while controlling for maternal variables. The results indicated that none of the paternal variables were predictors of complications in labor. Further, there was no clear pattern of results, though father's degree of exposure to solvents, and exposures to radiation did reach significance in some analyses.« less

Preventing fetal alcohol spectrum disorders (FASDs) requires detection of in-pregnancy maternal risk drinking. The widely used T-ACE screen has been applied in various ways, although the impact of those different uses on effectiveness is uncertain. We examined relations among different T-ACE scoring criteria, maternal drinking, and child outcome. Self-reported across-pregnancy maternal drinking was assessed in 75 African-American women. The different T-ACE criteria used varied the level of drinking that defined tolerance (two or three drinks) and the total T-ACE score cut-points (two or three). Receiver operator curves and regression analysis assessed the significance of relations. Increasing the total T-ACE score cut-point to 3 almost doubled specificity in detecting risk drinking whereas maintaining adequate sensitivity, equivalent to that in the original report, and identified substantially more neurobehavioral deficits in children. Redefining tolerance at three drinks did not improve T-ACE effectiveness in predicting outcomes. This study is among the first to show the ability of an in-pregnancy T-ACE assessment to predict child neurodevelopmental outcome. In addition, increasing the total T-ACE score criterion (from 2 to 3) improved identification of non-drinking mothers and unaffected children with little loss in detection of drinkers and affected children. Efficient in-pregnancy screens for risk drinking afford greater opportunities for intervention that could prevent/limit FASDs. Published by Elsevier Inc.

We sought to explore the clinical variables associated with the loss of rubella immunity during pregnancy and to determine if these changes are linked to obstetrical complications. This is a case-control study in which women were identified whose rubella antibody titers were equivocal or non-immune and compared to those who had retained immunity. Two hundred and eighty-five cases were identified and compared to the same number of controls using Student's t test, Mann-Whitney U-test or Fisher's exact test. Univariate and multivariate logistic regressions were employed. Subjects with diminished immunity were more likely to have public insurance and higher gravidity with a trend toward increased tobacco use. Diminished rubella immunity was not associated with adverse obstetrical outcomes, including preterm birth and pre-eclampsia and is likely not a risk factor for these pregnancy outcomes. While no adverse pregnancy outcomes were associated with a loss of rubella immunity, women with greater number of pregnancies appear to lose their immunity to rubella. This relationship needs to be explored further and if proven, revaccination prior to pregnancy may need to be addressed.

Background & Objectives : We report 17 years outcome of subsequent pregnancies of women with severe Mitral Stenosis (MS) who underwent Mitral Balloon Valvuloplasty (MBV) during pregnancy and the follow up of the children born of such pregnancies. Methods: Twenty three pregnant patients suffering from severe MS (NYHA-New York Heart Association class III/IV) who underwent MBV by Inoue balloon catheter technique during second trimester were enrolled. The study was performed between January 1992 and December 2008 at King Faisal Specialist Hospital & Research Centre, Riyadh, Saudi Arabia, during which time, details about the obstetric outcome and childhood development were recorded. Mean follow up period was 10± 5.5 years (range 1-17 years). Results: MBV was successful in all patients with improvement in their NYHA class to I/II. All patients were followed until term and had uneventful course after MBV. Twenty two (95.6%) patients delivered 23 babies including a twin birth. These children exhibited normal growth and development according to their age. Nineteen patients had further pregnancies and gave birth to 38 live & healthy babies with one still birth and no unfavorable maternal outcome. Of these, 97.4% were singleton pregnancies while 2.6% were twin pregnancies. Spontaneous abortions were recorded in 21.5% and there was one still birth (2.5%) and one ectopic pregnancy (2.5%). Conclusion : Mitral Balloon Valvuloplasty is a safe and useful procedure during pregnancy, with no short or long term adverse affects on the mothers and their obstetric future. The children born of subsequent pregnancies exhibited normal physical and mental development. PMID:24639837

To find out the outcome of a cohort of women with pregnancy of unknown location presenting to a tertiary care hospital. The prospective study was conducted from January to December, 2011, at Early Pregnancy Assessment Unit, King Faisal Military Hospital, Khamis Mushait, Saudi Arabia. Data was collected for women with early pregnancy or with history of amenorrhoea, bleeding or pain. These women were investigated with serum beta-human chorionic gonadotrophin levels twice weekly and transvaginal ultrasonography weekly. Expectant management was done for failing pregnancy of unknown location while medical or surgical management was considered for persistent pregnancy of unknown location and ectopic pregnancy. During study period, 7215 patients were admitted, and, of them, 2212(30.6%) were patients with early pregnancy. Meeting the inclusion criteria were 183(2.53%) patients who formed the study sample. There were 131(71.6%) patients presenting with amenorrhoea, 90(49.2%) had bleeding and 93(50.8%) presented with pain. Outcome of 100(54.6%) patients was failing pregnancy of unknown location, 58(31.7%) had intrauterine pregnancy, 14(7.7%) converted to ectopic pregnancy, while 11(6%) had persistent pregnancy of unknown location. All patients with persistent pregnancy of unknown location and 5(36%) patients with ectopic pregnancy were medically treated. Five (36%) patients having ectopic pregnancy were managed surgically. Management of choice for asymptomatic patients having pregnancy of unknown location is expectant management. Most of the patients suspected to have Most of the patients with persistent pregnancy of unknown location and ectopic pregnancy can be managed medically.

Background Complications in early pregnancy, such as threatened or actual miscarriage is a common occurrence resulting in many women presenting to the emergency department (ED). Early pregnancy service delivery models described in the literature vary in terms of approach, setting and outcomes. Our objective was to determine outcomes of women who presented to an Australian regional ED with diagnoses consistent with early pregnancy complications following the implementation of an early pregnancy assessment service (EPAS) and early pregnancy assessment protocol (EPAP) in July 2011. Methods A descriptive, comparative (6 months before and after) study was undertaken. Data were extracted from the hospital ED information system and medical healthcare records. Outcome measures included: time to see a clinician, ED length of stay, admission rate, re-presentation rate, hospital admission and types of pathology tests ordered. Results Over the 12 -month period, 584 ED presentations were made to the ED with complications of early pregnancy (268 PRE and 316 POST EPAS–EPAP). Outcomes that improved statistically and clinically following implementation included: time to see a clinician (decreased by 6 min from 35 to 29 min), admission rate (decreased 6% from 14.5% to 8.5%), increase in β-human chorionic gonadotrophin ordering by 10% (up to 80% POST), increase in ultrasound (USS) performed by 10% (up to 73% POST) and increase in pain score documentation by 23% (up to 36% POST). Conclusions The results indicate that patient and service delivery improvements can be achieved following the implementation of targeted service delivery models such as EPAS and EPAP in the ED.

In pregnant women, antiphospholipid syndrome (APS) is associated with an increased risk of preeclampsia, fetal intrauterine growth restriction, and other complications related to uteroplacental insufficiency. In the last two decades, several studies were performed to identify the predictive role of some parameters in relation to obstetric outcome in APS patients. Among these, the uterine velocimetry Doppler is the most studied. It provides a non-invasive method for the study of uteroplacental blood flow, being able to detect a condition of impaired placental perfusion, due to the presence of circulating antiphospholipid antibodies (aPL). To date, the uterine artery Doppler velocimetry resulted to be a useful tool to identify APS pregnancies at higher risk of adverse pregnancy outcome. False-positive IgM for toxoplasmosis, others, rubella, cytomegalovirus, herpes viruses (TORCH) complex is associated to a worse pregnancy outcome because it reflects a dysregulation of the immune system which may amplify placental autoimmune damage. Moreover low levels of complement components are related to an increased incidence of obstetrical complications, suggesting that placental deposition of immune complexes and activation of complement cascade may contribute to placental failure APS related. The abnormal uterine Doppler velocimetry, false-positive TORCH IgM and low levels of complement components can be considered prognostic indexes of poor pregnancy outcome in APS.

Bacterial invasion in subgingival sites especially of gram-negative organisms are initiators for periodontal diseases. The periodontal pathogens with persistent inflammation lead to destruction of periodontium. In recent years, periodontal diseases have been associated with a number of systemic diseases such as rheumatoid arthritis, cardiovascular-disease, diabetes mellitus, chronic respiratory diseases and adverse pregnancy outcomes including pre-term low-birth weight (PLBW) and pre-eclampsia. The factors like low socio-economic status, mother's age, race, multiple births, tobacco and drug-abuse may be found to increase risk of adverse pregnancy outcome. However, the same are less correlated with PLBW cases. Even the invasion of both aerobic and anerobic may lead to inflammation of gastrointestinal tract and vagina hence contributing to PLBW. The biological mechanism involved between PLBW and Maternal periodontitis is the translocation of chemical mediators of inflammation. Pre-eclampsia is one of the commonest cause of both maternal and fetal morbidity as it is characterized by hypertension and hyperprotenuria. Improving periodontal health before or during pregnancy may prevent or reduce the occurrences of these adverse pregnancy outcomes and, therefore, reduce the maternal and perinatal morbidity and mortality. Hence, this article is an attempt to review the relationship between periodontal condition and altered pregnancy outcome.

Bipolar disorder in pregnancy and childbirth: a systematic review of outcomes.

Rusner, Marie; Berg, Marie; Begley, Cecily

Bipolar Disorder (BD) is a mental disorder usually diagnosed between 18 and 30 years of age; this coincides with the period when many women experience pregnancy and childbirth. As specific problems have been reported in pregnancy and childbirth when the mother has BD, a systematic review was carried out to summarise the outcomes of pregnancy and childbirth, in mother and child, when the mother has BD diagnosed before pregnancy. An a priori protocol was designed and a systematic search conducted in PubMed, CINAHL, Scopus, PsycINFO and Cochrane databases in March 2015. Studies of all designs were included if they involved women with a diagnosis of bipolar disorder prior to pregnancy, who were pregnant and/or followed up to one year postpartum. All stages of inclusion, quality assessment and data extraction were done by two people. All maternal or infant outcomes were examined, and narrative synthesis was used for most outcomes. Meta-analysis was used to achieve a combined prevalence for some outcomes and, where possible, case and control groups were combined and compared. The search identified 2809 papers. After screening and quality assessement (using the EPHPP and AMSTAR tools), nine papers were included. Adverse pregnancy outcomes such as gestational hypertension and antepartum haemorrhage occur more frequently in women with BD. They also have increased rates of induction of labour and caesarean section, and have an increased risk of mood disorders in the postnatal period. Women with BD are more likely to have babies that are severely small for gestational age (<2nd-3rd percentile), and it appears that those women not being treated with mood stabilisers in pregnancy might not have an increased risk of having a baby with congenital abnormalities. Due to heterogeneity of data, particularly the use of differing definitions of bipolar disorder, narrative synthesis was used for most outcomes, rather than a meta-analysis. It is evident that adverse outcomes are more

The National Smallpox Vaccine in Pregnancy Registry (NSVIPR) actively follows women inadvertently vaccinated with smallpox vaccine during or shortly before pregnancy to evaluate their reproductive health outcomes. Approximately 65% of NSVIPR participants also inadvertently received Anthrax Vaccine Adsorbed (AVA) while pregnant, providing a ready opportunity to evaluate pregnancy and infant health outcomes among these women. AVA-exposed pregnancies were ascertained using NSVIPR and electronic healthcare data. Rates of pregnancy loss and infant health outcomes, including major birth defects, were compared between AVA-exposed and AVA-unexposed pregnancies. Analyses included AVA-exposed and AVA-unexposed pregnant women who also received smallpox vaccine 28 days prior to or during pregnancy. Rates of adverse outcomes among the AVA-exposed group were similar to or lower than expected when compared with published reference rates and the AVA-unexposed population. The findings provide reassurance of the safety of AVA when inadvertently received by a relatively young and healthy population during pregnancy. Copyright © 2015 Elsevier Ltd. All rights reserved.

Objective: To evaluate the frequency of fetomaternal outcome of pregnancy with Mitral stenosis admitted in Civil Hospital Karachi. Methods: It was a two years descriptive study done in the Department of Obstetrics and Gynaecology Civil Hospital Karachi. All pregnant women with a known or newly diagnosed Mitral stenosis on echocardiography were included in the study. History was taken regarding age, parity, gestational age (calculated by ultrasound) and complaints. Mode of delivery and Maternal mortality noted. Foetal outcome was analyzed by birth weight and Apgar score. Results: A total of 101 patients meeting the inclusion criteria were enrolled in the study. The ages of the women ranged between 20-29 years (69%) and 81% were multigravidas. Vaginal delivery occurred in 67 (66.3%) women and 78.3% were term pregnancies. Preterm deliveries were 21.8% and 27.7% newborns were low birth weight. APGAR score <7 was found in 14.9% of neonates and 9 babies had intrauterine death. Low ejection fraction<55% was diagnosed in 20(13.9%) women and Maternal mortality was found in two cases. Conclusion: Heart disease in pregnancy is associated with significant morbidity, it should be carefully managed in a tertiary care hospital to obtain optimum maternal and foetal outcome.

Maternal employment during pregnancy and birth outcomes: evidence from Danish siblings.

PubMed

Wüst, Miriam

2015-06-01

I use Danish survey and administrative data to examine the impact of maternal employment during pregnancy on birth outcomes. As healthier mothers are more likely to work and health shocks to mothers may impact employment and birth outcomes, I combine two strategies: First, I control extensively for time-varying factors that may correlate with employment and birth outcomes, such as pre-pregnancy family income and maternal occupation, pregnancy-related health shocks, maternal sick listing, and health behaviors (smoking and alcohol consumption). Second, to account for remaining time-invariant heterogeneity between mothers, I compare outcomes of mothers' consecutive children. Mothers who work during the first pregnancy trimester have a lower risk of preterm birth. I find no effect on the probability of having a baby of small size for gestational age. To rule out that health selection of mothers between pregnancies drives the results, I focus on mothers whose change in employment status is likely not to be driven by underlying health (mothers who are students in one of their pregnancies and mothers with closely spaced births). Given generous welfare benefits and strict workplace regulations in Denmark, my findings support a residual explanation, namely, that exclusion from employment may stress mothers in countries with high-female employment rates.

To examine the prevalence of snoring during pregnancy and its effects on key pregnancy outcomes. Pregnant women were consecutively recruited in their first trimester. Habitual snoring was screened by using a questionnaire in the 1st and 3rd trimester, respectively. According to the time of snoring, participants were divided into pregnancy onset snorers, chronic snorers and non-snorers. Logistic regressions were performed to examine the associations between snoring and pregnancy outcomes. Of 3 079 pregnant women, 16.6% were habitual snorers, with 11.7% were pregnancy onset snorers and 4.9% were chronic snorers. After adjusting for potential confounders, chronic snorers were independently associated with gestational diabetes mellitus (GDM) (RR 1.66, 95%CI 1.09-2.53). Both pregnancy onset and chronic snorers were independently associated with placental adhesion (RR 1.96, 95%CI 1.17-3.27, and RR 2.33, 95%CI 1.22-4.46, respectively). Pregnancy onset snorers were at higher risk of caesarean delivery (RR 1.37, 95%CI 1.09-1.73) and having macrosomia (RR 1.54, 95%CI 1.05-2.27) and large for gestational age (LGA) (RR 1.71, 95%CI 1.31-2.24) infants. In addition, being overweight or obese before pregnancy plays an important role in mediating snoring and adverse pregnancy outcomes. Maternal snoring may increase the risk of adverse pregnancy outcomes, and being overweight or obese before pregnancy with snoring is remarkable for researchers. Further studies are still needed to confirm our results.

Status epilepticus (SE) in pregnancy carries significant risk to both mother and fetus. There is limited literature available on SE occurring in pregnancy world-over, with majority being from obstetric centers. All women who developed SE related to pregnancy (gestation, labor, or puerperium) between January 2000 and December 2016 were included in the study. Data were collected from our SE registry, maintained, and archived in the institute. The variables influencing the maternal and fetal outcome were compared using Student's t-test for continuous variables and Fisher's exact test for discrete variables. During the 16-year study period, a total of 348 SE events were recorded in 294 patients. Among these, there were 138 women, of which 17 had SE related to pregnancy. The etiology of SE was remote symptomatic in two and acute symptomatic in 15 patients. The various causes detected after initial evaluation for acute symptomatic SE were eclampsia (n=4), posterior reversible encephalopathy syndrome due to various causes other than eclampsia (n=6), cortical venous thrombosis (n=3), subarachnoid hemorrhage (n=1), and NMDA receptor antibody-mediated encephalitis (n=1).13 of 17 women with SE (76%) had good outcome. Majority of the fetuses had good outcomes, i.e., Category 1 (n=9, 57%). Duration of intensive care unit stay (p=0.029) and Status Epilepticus Severity Score (p=0.0324) at admission, were found to be significantly associated with poor outcomes. In any patient presenting with SE occurring in pregnancy, though eclampsia is presumed to be the most common overall cause; it is relevant to consider other etiologies such as posterior reversible encephalopathy syndrome, cortical venous thrombosis, and autoimmune encephalitis especially in cases presenting with refractory SE. Posterior reversible encephalopathy may occur in pregnancy due to diverse etiologies other than eclampsia. Copyright © 2017 Elsevier Inc. All rights reserved.

Factors affecting retention of early pregnancy in dairy cattle.

Potential factors affecting retention of pregnancy during weeks 5-9 of gestation were studied in dairy cows and heifers (N = 211) on two farms. Cows were examined by ultrasonography for presence of a viable embryo, and sizes of the corpus luteum (CL) and of follicles > or = 5mm were recorded. Blood samples were taken at each examination and assayed for progesterone and estradiol. Overall pregnancy loss was 11.4%. Cows with two CL did not have greater concentrations of progesterone than cows with one CL and they retained fewer pregnancies (P < 0.01; 73% versus 91%). Pregnancy retention was associated positively with concentrations of progesterone and estradiol during week 5 (P < 0.05). Embryos that were lost apparently died before CL regression. Retention of pregnancy declined in cows with high body condition and as age of the cow increased. Pregnancy retention was lower in cows bred to one of four frequently-used service sires (P < 0.05). Days postpartum, milk production, parity, service number, inseminator, synchronization of estrus, diameter of follicles and size of CL did not affect pregnancy retention. In conclusion, retention of pregnancy during placentation varied with concentrations of progesterone and estradiol, age of cow, body condition and service sire.

The authors sought to determine whether pregnancies in adolescents following an abortion of pregnancy is associated with an elevated risk for adverse perinatal outcomes. In a cohort study of all adolescent (younger than 18 years) deliveries over a 4-year period at 1 institution, we compared nulliparous women with a history of a prior abortion (cases) to those without a spontaneous loss or abortion of pregnancy (referent) for adverse perinatal outcomes, including preterm birth and fetal growth restriction. Of the 654 included nulliparous adolescent deliveries, 102 (16%) had an abortion before the index pregnancy. Compared with the referent group, adolescents with a history of a abortion were older (17.8 ± 0.8 vs 16.7 ± 1.2 years, P = .0001), enrolled earlier for prenatal care (14.4 ± 5.6 vs 17.2 ± 7.6 weeks, P = .0004), along with a higher incidence of African American race (95% vs 88%, P = .05). The groups did not differ with respect to other maternal demographics. Perinatal outcomes, including spontaneous preterm birth, abnormal placentation, birth weight, and gestational age at delivery, did not differ between the 2 groups. Compared with adolescent women who had just delivered and did not have a prior abortion, women who had just delivered and had a previous abortion were more likely to be older at the age of their first pregnancy and more likely to initiate early prenatal care. Thus, having a prior abortion may improve the health of a pregnancy though adverse outcomes do not differ between the 2 groups.

Background Infants in utero during the terrorist attacks of September 11, 2001 may have been negatively affected by maternal stress. Studies to date have produced contradictory results. Methods Data for this retrospective cohort study were obtained from the Department of Defense Birth and Infant Health Registry and included up to 164,743 infants born to active-duty military families. Infants were considered exposed if they were in utero on September 11, 2001, while the referent group included infants gestating in the same period in the preceding and following year (2000 and 2002). We investigated the association of this acute stress during pregnancy with the infant health outcomes of male:female sex ratio, birth defects, preterm birth, and growth deficiencies in utero and in infancy. Results No difference in sex ratio was observed between infants in utero in the first trimester of pregnancy on September 11, 2001 and infants in the referent population. Examination of the relationship between first-trimester exposure and birth defects also revealed no significant associations. In adjusted multivariable models, neither preterm birth nor growth deficiencies were significantly associated with the maternal exposure to the stress of September 11 during pregnancy. Conclusion The findings from this large population-based study suggest that women who were pregnant during the terrorist attacks of September 11, 2001 had no increased risk of adverse infant health outcomes.

Our aims were to assess the frequency of false-positive IgM antibodies for cytomegalovirus in pregnant women with autoimmune diseases and in healthy women (controls) and to determine their relationship with pregnancy outcome. Data from 133 pregnancies in 118 patients with autoimmune diseases and from 222 pregnancies in 198 controls were assessed. When positive IgM for cytomegalovirus was detected, IgG avidity, cytomegalovirus isolation and polymerase chain reaction for CMV-DNA in maternal urine and amniotic fluid samples were performed in order to identify primary infection or false positivity. A statistically significantly higher rate of false-positive IgM was found in pregnancies with autoimmune diseases (16.5%) in comparison with controls (0.9%). A worse pregnancy outcome was observed among patients with autoimmune disease and false cytomegalovirus IgM in comparison with those without false positivity: earlier week of delivery (p = 0.017), lower neonatal birth weight (p = 0.0004) and neonatal birth weight percentile (p = 0.002), higher rate of intrauterine growth restriction (p = 0.02) and babies weighing less than 2000 g (p = 0.025) were encountered. The presence of false cytomegalovirus IgM in patients with autoimmune diseases could be used as a novel prognostic index of poor pregnancy outcome: it may reflect a non-specific activation of the immune system that could negatively affect pregnancy outcome.

To investigate the incidence of adverse pregnancy outcomes in couples with an unexplained Recurrent Pregnancy Loss (RPL) history, a retrospective cohort study was conducted between 2014 and 2015. The study group (A) included couples with an unexplained RPL, and the control group (B) was composed of couples who attended the Low-Risk Antenatal Unit during the same period. On the other hand, 53 couples were included in the study group (A) and on the other hand, 65 in the control group (B). Women with previous unexplained recurrent pregnancies loss had a significantly increased risk of gestational diabetes with 12 cases (22.6%) in the study group and 3 cases (4.6%) in the control (OR: 6.048; 95% CI: 1.607-22.762; p = 0.007). A slight increase in the risk of preterm delivery and hepatic cholestasis was observed in the study group (6 cases, 11.3%, in study group and 1 case, 1.5% in the controls (OR: 8.170; 95% CI: 0.951-70.158; p = 0.0555). Women with a history of RPL delivered more frequently by caesarean section (OR: 3.252; 95% CI: 1.460-7.241; p = 0.0039). Women with a history of RPL were at an increased risk for adverse pregnancy outcomes, mainly gestational diabetes. Therefore, a closer surveillance during the antenatal period is recommended in this group of patients.

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.

Objective Whether areas affected by Q fever during a large outbreak (2008–2010) had higher rates of adverse pregnancy outcomes than areas not affected by Q fever. Design Nationwide registry-based ecological study. Setting Pregnant women in areas affected and not affected by Q fever in the Netherlands, 2003–2004 and 2008–2010. Participants Index group (N=58 737): pregnant women in 307 areas with more than two Q fever notifications. Reference group (N=310 635): pregnant women in 921 areas without Q fever notifications. As a baseline, pregnant women in index and reference areas in the years 2003–2004 were also included in the reference group to estimate the effect of Q fever in 2008–2010, and not the already existing differences before the outbreak. Main outcome measures Preterm delivery, small for gestational age, perinatal mortality. Results In 2008–2010, there was no association between residing in a Q fever-affected area and both preterm delivery (adjusted OR 1.01 (95% CI 0.94 to 1.08)), and perinatal mortality (adjusted OR 0.87 (95% CI 0.72 to 1.05)). In contrast, we found a weak significant association between residing in a Q fever-affected area in 2008–2010 and small for gestational age (adjusted OR 1.06 (95% CI 1.01 to 1.12)), with a population-attributable fraction of 0.70% (95% CI 0.07% to 1.34%). We observed no dose–response relation for this outcome with increasing Q fever notifications, and we did not find a stronger association for women who were in their first trimester of pregnancy during the months of high human Q fever incidence. Conclusions This study found a weak association between residing in a Q fever-affected area and the pregnancy outcome small for gestational age. Early detection of infection would require mass screening of pregnant women; this does not seem to be justified considering these results, and the uncertainties about its efficacy and the adverse effects of antibiotic treatment.

Illegal drug abuse causes significant health problems with consequences to the mother and the neonate, and an economic burden to the health system. The present study aimed to investigate pregnancy and perinatal outcome in women using illegal drugs prior to and during pregnancy. A retrospective cohort study comparing pregnancy and neonatal outcomes of drug addicted women to the outcomes of other Jewish women. The study population includes all women who gave birth between the years 1989-2008 at the Soroka University Medical Center. From a total of 106,000 deliveries, 119 women were known to be drug addicted. No significant differences were found between the groups regarding maternal age and origin, but more women in the addicted group smoked, and tacked prenatal care. More women in the addicted group had obstetrics complications such as: recurrent abortions, placenta previa, pLacental abruption and preterm labor. Illegal drug abuse was significantly associated with adverse perinatal outcomes such as low birth weight, congenital anomalies, peripartum death and prolonged hospitalizations. Illegal drug abuse is an independent risk factor for adverse obstetric and perinatal outcomes. This study investigated a significant problem that may be underestimated in our population. The higher incidence of pLacental abruption, placenta previa, preterm tabor and low birth weight could be a sign for placentaL insult. Illegal drug abuse is an independent risk factor for adverse perinatal outcomes and causes an economic burden. Further national studies are needed to characterize the problem, and to develop appropriate intervention programs.

Exposure to arsenic has a number of known detrimental health effects but impact on pregnancy outcomes is not as widely recognized. This narrative review examines existing epidemiological evidence investigating the association between arsenic exposure via drinking water and adverse pregnancy outcomes. We reviewed published epidemiological studies from around the world on impact of chronic arsenic exposure on spontaneous abortion, stillbirth, neonatal death, post neonatal death, low birth weight and preterm baby. Plausible mechanisms of arsenic toxicity causing adverse pregnancy outcomes were also determined through literature review. There is convincing evidence to support the association between high inorganic arsenic exposure (>50 ppb) and spontaneous abortion, stillbirth and low birth weight. Limitations of certain studies include study design, small sample size, recall constraints and exposure assessment. There needs to be further research investigating the dose metered impact of arsenic exposure on pregnancy outcomes. Further research on impact of low-moderate arsenic concentration exposure on pregnancy outcomes will allow for appropriate public health policy recommendations.

Reports of pregnancy in liver transplantation (LT) patients have largely favorable outcomes. Concerns remain with regards to maternal and graft risk, optimal immunosuppression (IS), and fetal outcomes. We review all post-LT pregnancies at our center with regard to the outcomes and safety for the patient, graft, and fetus. A total of 117 conceptions occurred in 79 patients. Median age at conception was 29 years. Maternal complications included graft loss (2%), acute cellular rejection (ACR; 15%), pre-eclampsia/eclampsia (15%), gestational diabetes (7%), and bacterial sepsis (5%). ACR was significantly more common in those women who conceived within 12 months of LT (P = 0.001). The live birth rate was 73%. Prematurity occurred in 26 (31%) neonates, and 24 (29%) neonates were of low or very low birth weight. IS choice (cyclosporine versus tacrolimus) had no significant effect on pregnancy outcomes and complications. No congenital abnormalities occurred, and only 1 child born at 24 weeks had delayed developmental milestones. In conclusion, pregnancy following LT has a favorable outcome in the majority, but severe maternal risks remain. Patients should be counseled with regard to the above information so informed decisions can be made, and pregnancy must be considered high risk with regular monitoring by transplant clinicians and specialist obstetricians. © 2015 American Association for the Study of Liver Diseases.

Pregnancy associated with aplastic anemia (AA) is a rare and heterogeneous disorder. We aimed to identify and evaluate the maternal and pregnant outcomes of pregnancy-associated severe AA treated with supportive care. A 25-year retrospective study was conducted at in a single center between 1990 and 2014 with pregnancy associated severe AA. In addition, relevant published cases of antenatally diagnosed pregnancy-associated severe AA after 1990 were identified by PubMed. The main goal was to determine the impact of various risk factors on maternal and fetal outcomes. 15 women with 18 pregnancies were enrolled. With addition of the published reports in literature, a total of 36 cases were included for reference review. Univariate analysis showed that low platelet counts (<2.0 × 10 9 /L), bone marrow hypocellularity (<25%), and late diagnosis during pregnancy were predictors of poor maternal outcomes (P < 0.05). The complication rate of pregnancy outcomes was 53.3%, including preterm delivery, small gestational age (SGA), preterm premature ruptured of membranes (PPROM) and preeclampsia. This study identified the risk factors of mortality and morbidity in pregnant women with severe AA, as well as the obstetrical complications associated with neonatal outcome. Copyright © 2017.

Although most infections with the rubella virus result in relatively minor sequelae, rubella infection in early pregnancy may lead to severe adverse outcomes for the fetus. First recognized in 1941, congenital rubella syndrome (CRS) can manifest with a diverse range of symptoms, including congenital cataracts, glaucoma, and cardiac defects, as well as hearing and intellectual disability. The gestational age of the fetus at the time of the maternal rubella infection impacts the probability and severity of outcomes, with infection in early pregnancy increasing the risks of spontaneous termination (miscarriage), fetal death (stillbirth), birth defects, and reduced survival for live-born infants. Rubella vaccination continues to change the epidemiology of rubella and CRS globally, but no models currently exist to evaluate the economic benefits of rubella management. This systematic review provides an overall assessment of the weight of the evidence for the outcomes associated with rubella infections in the first 20 weeks of pregnancy. We identified, evaluated, and graded 31 studies (all from developed countries) that reported on the pregnancy outcomes of at least 30 maternal rubella infections. We used the available evidence to estimate the increased risks of spontaneous termination, fetal death, infant death, and CRS as a function of the timing of rubella infection in pregnancy and decisions about induced termination. These data support the characterization of the disability-adjusted life years for outcomes associated with rubella infection in pregnancy. We find significant impacts associated with maternal rubella infections in early pregnancy, which economic analyses will miss if they only focus on live births of CRS cases. Our estimates of fetal loss from increased induced terminations due to maternal rubella infections provide context that may help to explain the relatively low numbers of observed CRS cases per year despite potentially large burdens of disease.

To estimate the efficacy of iron supplementation in anemic pregnant women on the basis of occurrence of pregnancy complications and birth outcomes. Comparison of the occurrence of medically recorded pregnancy complications and birth outcomes in pregnant women affected with medically recorded iron deficiency anemia and iron supplementation who had malformed fetuses/newborns (cases) and who delivered healthy babies (controls) in the population-based Hungarian Case-Control Surveillance System of Congenital Abnormalities. Of 22,843 cases with congenital abnormalities, 3242 (14.2%), while of 38,151 controls, 6358 (16.7%) had mothers with anemia. There was no higher rate of preterm births and low birth weight in the newborns of anemic pregnant women supplemented by iron. However, anemic pregnant women without iron treatment had a significantly shorter gestational age at delivery with a somewhat higher rate of preterm births but these adverse birth outcomes were prevented with iron supplementation. The rate of total and some congenital abnormalities was lower than expected and explained mainly by the healthier lifestyle and folic acid supplements. The secondary findings of the study showed a higher risk of constipation-related hemorrhoids and hypotension in anemic pregnant women with iron supplementation. A higher rate of preterm birth was found in anemic pregnant women without iron treatment but this adverse birth outcome was prevented with iron supplementation. There was no higher rate of congenital abnormalities in the offspring of anemic pregnant women supplemented with iron and/or folic acid supplements. Copyright © 2011 Elsevier Inc.

To examine the association between interpregnancy interval and maternal-neonate health when matching women to their successive pregnancies to control for differences in maternal risk factors and compare these results with traditional unmatched designs. We conducted a retrospective cohort study of 38,178 women with three or more deliveries (two or greater interpregnancy intervals) between 2000 and 2015 in British Columbia, Canada. We examined interpregnancy interval (0-5, 6-11, 12-17, 18-23 [reference], 24-59, and 60 months or greater) in relation to neonatal outcomes (preterm birth [less than 37 weeks of gestation], small-for-gestational-age birth [less than the 10th centile], use of neonatal intensive care, low birth weight [less than 2,500 g]) and maternal outcomes (gestational diabetes, beginning the subsequent pregnancy obese [body mass index 30 or greater], and preeclampsia-eclampsia). We used conditional logistic regression to compare interpregnancy intervals within the same mother and unconditional (unmatched) logistic regression to enable comparison with prior research. Analyses using the traditional unmatched design showed significantly increased risks associated with short interpregnancy intervals (eg, there were 232 preterm births [12.8%] in 0-5 months compared with 501 [8.2%] in the 18-23 months reference group; adjusted odds ratio [OR] for preterm birth 1.53, 95% confidence interval [CI] 1.35-1.73). However, these risks were eliminated in within-woman matched analyses (adjusted OR for preterm birth 0.85, 95% CI 0.71-1.02). Matched results indicated that short interpregnancy intervals were significantly associated with increased risk of gestational diabetes (adjusted OR 1.35, 95% CI 1.02-1.80 for 0-5 months) and beginning the subsequent pregnancy obese (adjusted OR 1.61, 95% CI 1.05-2.45 for 0-5 months and adjusted OR 1.43, 95% CI 1.10-1.87 for 6-11 months).

The issue of travel to developing countries during pregnancy has not been sufficiently studied. The aim of this study is to investigate the rate, course, and outcome of pregnancies in women who traveled to developing countries while pregnant, or became pregnant during such travel. Women visiting two major travel clinics in Israel for consultation within the years 2004 to 2009, who were pregnant or declared an intention of becoming pregnant during travel were contacted. This was followed by a telephone interview by an obstetrician with those women who were actually pregnant. Background characteristics, morbidity during travel, and pregnancy course and outcome were collected. Overall 52,430 travelers' records had been screened. Of these, we identified 49 women who were pregnant during their trip, but 3 declined participation. Of the remaining 46 women, 33 were pregnant at departure, and 13 conceived during travel. The incidence of pregnancy during travel was thus 0.93/1000 travelers. Thirty-three women traveled to East Asia, 8 to South and Central America, 5 to Africa. More than two thirds of women received pretravel vaccinations. Adherence to the World Health Organization recommendations regarding food and drink was high (87%) and travelers' diarrhea occurred in only 11% of women. Five of 22 women traveling to malarious areas had taken antimalarial prophylaxis. Six women required medical therapy during travel. Pregnancy outcome was not different from the normal population except for an unusually low rate of preterm delivery. In this cohort, travel to developing countries was not associated with adverse pregnancy outcome. Larger studies are needed to support these findings. © 2012 International Society of Travel Medicine.

Women with antiphospholipid antibodies (aPL) such as lupus anticoagulant, anticardiolipin antibodies, and anti-β(2) glycoprotein-1 antibodies are at high risk of late pregnancy complications, such as severe pre-eclampsia, placental insufficiency, and fetal loss. It has been observed that aPL consists of a heterogeneous group of antibodies targeting several phospholipid-binding plasma proteins, including also anti-prothrombin (anti-PT), anti-protein S (anti-PS), and anti-protein C (anti-PC) antibodies. Their potential role in late pregnancy complications is not known. The aim of this work was to investigate the association between those autoantibodies and histories for adverse pregnancy outcome. Anti-PT, anti-PS, and anti-PC antibodies were evaluated in 163 patients with previous severe pre-eclampsia, fetal death, and/or placental abruption and in as many women with previous uneventful pregnancies, negative for aPL. The prevalence of anti-PT antibodies was higher in cases than in controls (OR, 95% CI: 10.92, 4.52-26.38). The highest prevalence was observed in subjects with fetal death. Anti-PT antibodies appear to be associated with adverse pregnancy outcome, irrespectively of aPL. © 2011 John Wiley & Sons A/S.

Sexual desire and frequency of sexual relationships during pregnancy remains challenging. This study aimed to assess factors that affect women's sexual functioning during pregnancy. This was a cross sectional study carried out at prenatal care clinics of public health services in Iran. An author-designed structured questionnaire including items on socio-demographic characteristics, obstetric history, the current pregnancy, and women's sexual functioning during pregnancy was used to collect data. The generalized linear model was performed in order to find out factors that affect women's sexual functioning during pregnancy. In all, 518 pregnant women participated in the study. The mean age of participants was 26.4 years (SD = 4.7). Overall 309 women (59.7%) scored less than mean on sexual functioning. The results obtained from generalized linear model demonstrated that that lower education, unwanted pregnancy, earlier stage of pregnancy, older age, and longer duration of marriage were the most important factors contributing to disturbed sexual functioning among couples. The findings suggest that sexual function during pregnancy might be disturbed due to several factors. Indeed issues on sexual relationship should be included as part of prenatal care and reproductive health programs for every woman.

Adverse Pregnancy Outcomes after Abnormal First Trimester Screening for Aneuploidy

Women with abnormal first trimester screening but with a normal karyotype are at risk for adverse pregnancy outcomes. A nuchal translucency >3.5mm is associated with an increased risk of subsequent pregnancy loss, fetal infection, fetal heart abnormalities and other structural abnormalities. Abnormal first trimester analytes are also associated with adverse pregnancy outcomes but the predictive value is less impressive. As a single marker, PAPP-A <1st%ile has a good predictive value for subsequent fetal growth restriction. Women with PAPP-A<5th%ile should undergo subsequent risk assessment with routine MSAFP screening with the possible addition of uterine artery PI assessment in the midtrimester. PMID:20638576

WHO recently recommended efavirenz (EFV) use for HIV infection through pregnancy, breastfeeding and childbearing age. However the use of EFV during pregnancy remains of concern and not all national guidelines reflect WHO advice. Few data are available concerning pregnancy outcomes. The objective of our study was to evaluate pregnancy outcomes in a cohort of women who conceived on EFV. A retrospective, multicenter cohort study was conducted in Pointe Noire, Republic of Congo (September 2005- June 2012). The following adverse pregnancy outcomes were considered: births defects, low birth weight, premature delivery, stillbirth and abortion, stratified by antiretroviral exposure at the time of conception. During the study period, 188 women conceived on antiretrovirals: 35 (18.6%) on EFV-based regimens and 153 (81.4%) on nevirapine-based regimens. Adverse pregnancy outcomes were observed in 17/35 (48.6%, 95% CI 33.0-64.4%) women in the EFV group and in 43/153 (28.1%, 95% CI 21.6-35.7%) in the non-EFV group (p=0.019). No birth defect was observed in either group. An increased incidence of adverse pregnancy outcomes was observed in the EFV group. As WHO is promoting a widespread use of EFV also for women in childbearing age, our study emphasizes the importance of launching large prospective cohort studies investigating pregnancy outcomes in exposed women.

Despite scientific advances in the field of physical problems during pregnancy, the effect of mental problems on the health of pregnant women is still an important issue that needs further research. To determine the association of symptoms of stress, anxiety and depression during pregnancy and there effect on the pregnancy outcome. This was a descriptive correlational study. The population included 200 pregnant women of the urban and rural health centers affiliated with Babol University of Medical Sciences. There were 100 each in second and third trimester. Convenience multi stage cluster sampling was performed. Data collection was received through the Hospital Anxiety Depression Scale (HADS), Pregnancy Distress Questionnaire (PDQ), and Perceived Stress Scale (PSS-14) questionnaires. The correlation results showed a significant difference between variables of depression, stress, and anxiety with birth weight, birth height and head circumference and infants' APGAR score (p<0.05). Multiple regression analysis showed that interpersonal relationships on prediction of infant weight (B=-0.324), anxiety on prediction of infant height (B=-0.197), stress on prediction of head circumference (B=-0.350) and depression on prediction of APGAR score (B=-0.323) are effective (p<0.001). The findings emphasize the need to identify women with depression, anxiety and stress in pregnancy, and scheduling to avoid adverse consequences of the pregnancy outcome.

While association between endometriosis and infertility is well established, there are few studies about the impact of endometriosis on adverse pregnancy outcomes. The aim of this study was to determine the effect of endometriosis on obstetric outcomes and whether the severity of the disease had an influence on these. We performed a retrospective study to investigate the obstetric outcomes of a population of 1204 subfertile women, including 258 with endometriosis, who obtained, thanks to assisted reproduction technology, a singleton pregnancy evolving beyond embryonic stage. Two analyzes were performed. The first compared women with endometriosis to women with other causes of infertility. The second observed adverse pregnancy outcomes according to AFS-R stages of endometriosis. The overall rate of live birth children was 95.8%. In case of endometriosis, there was a significant increase of the incidence of preterm delivery, especially before 32 weeks amenorrhea (6.2% vs 3.1% in the group "without endometriosis", P = 0.03), antenatal bleeding (5.3% vs 2.2%, P = 0.01) and placenta previa (4.9% vs 0.9%, P < 0.0001). The incidence of gestational diabetes was significantly decreased (0.4% vs 2.7%, P = 0.04). There was no correlation between endometriosis and cesarean section or preeclampsia, or between the AFS-R stage and adverse pregnancy outcomes. Endometriosis is a factor of obstetrical risk, independently of the infertility it causes. The AFS-R score does not seem to be representative of obstetric outcomes beyond first trimester of pregnancy for women with endometriosis. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

Psychoneuroimmunology in Pregnancy: Immune Pathways Linking Stress with Maternal Health, Adverse Birth Outcomes, and Fetal Development

PubMed Central

Christian, Lisa M.

2011-01-01

It is well-established that psychological stress promotes immune dysregulation in nonpregnant humans and animals. Stress promotes inflammation, impairs antibody responses to vaccination, slows wound healing, and suppresses cell-mediated immune function. Importantly, the immune system changes substantially to support healthy pregnancy, with attenuation of inflammatory responses and impairment of cell-mediated immunity. This adaptation is postulated to protect the fetus from rejection by the maternal immune system. Thus, stress-induced immune dysregulation during pregnancy has unique implications for both maternal and fetal health, particularly preterm birth. However, very limited research has examined stress-immune relationships in pregnancy. The application of psychoneuroimmunology research models to the perinatal period holds great promise for elucidating biological pathways by which stress may affect adverse pregnancy outcomes, maternal health, and fetal development.

Although the definition of a short interbirth interval has been inconsistent in the literature, Healthy People 2020 recommends that women wait at least 18 months after a live birth before attempting their next pregnancy. In the United States, approximately 33% of pregnancies are conceived within 18 months of a previous birth. Pregnancies that result from short interbirth intervals can pose serious risks. The objective of this study was to determine the association between interbirth interval and understudied pregnancy complications and outcomes, including small for gestational age (SGA) infants, premature rupture of membranes (PROM), preterm PROM (PPROM), placenta previa, and gestational diabetes, using Pregnancy Risk Assessment and Monitoring System data from Mississippi and Tennessee. This study collected self-reported information from 2212 women on interbirth interval (≤18 months, ie, short; 19-35 months, ie, intermediate; and ≥36 months, ie, long; referent), PPROM, placenta previa, and gestational diabetes. SGA and PROM data were obtained from birth certificates. Logistic regression was used to calculate odds ratios (ORs) and 95% CIs. After adjustment, there were no strong associations between interbirth interval and PPROM, gestational diabetes, or SGA infants. However, women with shorter intervals had increased odds of PROM (short: OR, 3.54; 95% CI, 1.22-10.23 and intermediate: OR, 4.09; 95% CI, 1.28-13.03) and placenta previa (short: OR, 2.58; 95% CI, 1.10-6.05 and intermediate: OR, 1.69; 95% CI, 0.94-3.05). The study's findings provide further support for encouraging women to space their pregnancies appropriately. Moreover, findings underscore the need to provide women with family planning services so that closely spaced pregnancies and unintended pregnancies can be avoided. Additional studies of the role of interbirth interval on these understudied pregnancy complications and outcomes are warranted. © 2018 by the American College of Nurse-Midwives.

Atypical HUS (aHUS) is a disorder most commonly caused by inherited defects of the alternative pathway of complement, or the proteins that regulate this pathway, and life-threatening episodes of aHUS can be provoked by pregnancy. We retrospectively and prospectively investigated 27 maternal and fetal pregnancy outcomes in 14 women with aHUS from the Vienna Thrombotic Microangiopathy Cohort. Seven pregnancies (26%) were complicated by pregnancy-associated aHUS (p-aHUS), of which three appeared to be provoked by infection, bleeding, and curettage, and three individuals were considered to have preeclampsia/HELLP syndrome before the definitive diagnosis of p-aHUS was made. Mutations in genes that encode the complement alternative pathway proteins or the molecules that regulate this pathway were detected in 71% of the women, with no relationship to pregnancy outcome. Twenty-one pregnancies (78%) resulted in a live birth, two preterm infants were stillborn, and four pregnancies resulted in early spontaneous abortions. Although short-term renal outcome was good in most women, long-term renal outcome was poor; among the 14 women, four had CKD stage 1-4, five had received a renal allograft, and three were dialysis-dependent at study end. We prospectively followed nine pregnancies of four women and treated six of these pregnancies with prophylactic plasma infusions (one pregnancy resulted in p-aHUS, one intrauterine fetal death occurred, and seven pregancies were uneventful). Our study emphasizes the frequency of successful pregnancies in women with aHUS. Close monitoring of such pregnancies for episodes of thrombotic microangiopathy is essential but, the best strategy to prevent these episodes remains unclear.

BACKGROUND The aim was to evaluate the impact of early pregnancy events and complications as predictors of adverse obstetric outcome. METHODS We conducted a literature review on the impact of first trimester complications in previous and index pregnancies using Medline and Cochrane databases covering the period 1980-2008. RESULTS Clinically relevant associations of adverse outcome in the subsequent pregnancy with an odds ratio (OR) > 2.0 after complications in a previous pregnancy are the risk of perinatal death after a single previous miscarriage, the risk of very preterm delivery (VPTD) after two or more miscarriages, the risk of placenta praevia, premature preterm rupture of membranes, VPTD and low birthweight (LBW) after recurrent miscarriage and the risk of VPTD after two or more termination of pregnancy. Clinically relevant associations of adverse obstetric outcome in the ongoing pregnancy with an OR > 2.0 after complications in the index pregnancy are the risk of LBW and very low birthweight (VLBW) after a threatened miscarriage, the risk of pregnancy-induced hypertension, pre-eclampsia, placental abruption, preterm delivery (PTD), small for gestational age and low 5-min Apgar score after detection of an intrauterine haematoma, the risk of VPTD and intrauterine growth restriction after a crown-rump length discrepancy, the risk of VPTD, LBW and VLBW after a vanishing twin phenomenon and the risk of PTD, LBW and low 5-min Apgar score in a pregnancy complicated by severe hyperemesis gravidarum. CONCLUSIONS Data from our literature review indicate, by finding significant associations, that specific early pregnancy events and complications are predictors for subsequent adverse obstetric and perinatal outcome. Though, some of these associations are based on limited or small uncontrolled studies. Larger population-based controlled studies are needed to confirm these findings. Nevertheless, identification of these risks will improve obstetric care.

To evaluate pregnancy and neonatal outcomes among deaf women using population-based vital records data in Washington State from 1987 to 2012. We performed a retrospective cohort study using the Washington State birth and fetal death records linked to state hospital discharge records to identify women with diagnosis codes for deafness indicated at their delivery hospitalization and compared them with randomly selected women without these codes. Pregnancy conditions and outcomes evaluated included gestational diabetes, preeclampsia, placental abruption, labor induction, and cesarean delivery. Neonatal outcomes evaluated included preterm gestational age (less than 28, 28 to less than 37 weeks) at delivery and low birth weight. We also assessed length of maternal and neonatal delivery hospitalization. We performed Poisson regression to estimate relative risks (RRs) and 95% CIs for each outcome, adjusting for birth year, maternal age, and parity. Most adverse pregnancy and neonatal outcomes were similar for deaf and comparison women. Among women who underwent vaginal delivery, deaf women were more than twofold (RR 2.15, 95% CI 1.43-3.22) more likely to have a delivery hospitalization of 4 or more days (6.0% compared with 2.8%). We found a modestly increased risk of cesarean delivery (RR 1.15, 95% CI 1.01-1.30), with 29.9% of deaf compared with 25.6% of nondeaf women having a cesarean delivery. Deaf women are not at increased risk of the majority of adverse pregnancy and neonatal outcomes. Obstetric care providers may use our findings in counseling this special population of prenatal patients.

Maternal HIV infection alters the immune balance in the mother and fetus; implications for pregnancy outcome and infant health.

With the rapid roll-out of combination antiretroviral therapy to prevent mother-to-child transmission of HIV, there is an annual increase in the number of uninfected infants born to HIV-infected women. Although the introduction of combination antiretroviral therapy has vastly improved pregnancy outcome and the health of infants born to HIV-infected women, concerns remain regarding the impact the maternal HIV infection on the pregnancy outcome and the health of HIV-exposed uninfected infants. Maternal HIV infection is associated with negative pregnancy outcomes such as low birth weight. In addition, an increased susceptibility to infections is reported in HIV-exposed uninfected infants compared with infants born to uninfected women. Studies have shown that HIV-exposure affects the maternal/fetal unit, with increase of proinflammatory cytokine produced by placental cells, as well as altered infant immune responses. These changes could provide the underlying conditions for negative pregnancy outcomes and facilitate mother-to-child transmission of HIV in the infant. Further studies are required to understand the underlying mechanisms and investigate whether these altered infant immune responses persist and have clinical consequences beyond childhood. HIV infection in pregnant women is associated with altered immune responses in HIV-infected women and their offspring with clinical consequences for pregnancy outcome and the HIV-exposed uninfected infant. Further studies are required to address the origin and long-term consequences of prenatal HIV-exposure and subsequent immune activation for infant health.

Antenatal care (ANC) has been shown to influence infant and maternal outcomes. WHO recommends 4 ANC visits for uncomplicated pregnancies. However, pregnant women in Ghana are required to attend 8-13 antenatal visits. We investigated the association of ANC attendance with adverse pregnancy outcomes (defined as low infant birth weight, stillbirth, preterm delivery or small for gestational age). A quantitative cross-sectional study was conducted on 629 women, age 19-48 years who presented for delivery at two selected public hospitals and 16 traditional birth attendants from July to November 2011. Socio-demographic and antenatal information were collected using a structured questionnaire. ANC attendance, medical and obstetric/gynecological history were abstracted from maternal antenatal records. Data were analyzed using Chi square and logistic regression. Twenty-two percent of the women experienced an adverse outcome. Eleven percent of the women attended <4 ANC visits. In an unadjusted model, these women had an increased likelihood of experiencing an adverse outcome (OR 2.27; 95% CI 1.30-3.94; p = 0.0038). High parity (>5 children) was also associated with adverse birth outcomes. Women screened for syphilis or use of insecticide-treated bed nets had a 40 and 36% (p = 0.0447 and p = 0.0293) reduced likelihood of experiencing an adverse pregnancy outcome respectively. After adjusting for confounders, attending <4 antenatal visits was associated with adverse pregnancy outcome compared with ≥4 ANC visits (Adjusted OR 2.55; 95% CI 1.16-5.63; p = 0.0202). Attending <4 antenatal visits and high parity were associated with adverse pregnancy outcomes for uncomplicated pregnancies.

Pregnancy is an immune challenge to the maternal immune system. The effects of pregnancy on maternal immunity and particularly on memory T cells during and after pregnancy are not fully known. This observational study aims to show the short term and the long term effects of pregnancy on the constitution, size and activation status of peripheral human memory T-lymphocyte populations. Effector memory (EM) and central memory (CM) T-lymphocytes were analyzed using flow cytometry of peripheral blood from 14 nulligravid, 12 primigravid and 15 parous women that were on average 18 months postpartum. The short term effects were shown by the significantly higher CD4+ EM cell and activated CD4+ memory cell proportions in primigravid women compared to nulligravid women. The persistent effects found in this study were the significantly higher proportions of CD4+ EM, CD4+ CM and activated memory T cells in parous women compared to nulligravid women. In contrast to CD4+ cells, activation status of CD8+ memory cells did not differ between the groups. This study shows that pregnancy persistently affects the pre-pregnancy CD4+ memory cell pool in human peripheral blood. During pregnancy, CD4+ T-lymphocytes might differentiate into EM cells followed by persistent higher proportions of CD4+ CM and EM cells postpartum. The persistent effects of pregnancy on memory T cells found in this study support the hypothesis that memory T cells are generated during pregnancy and that these cells could be involved in the lower complication risks in multiparous pregnancies in humans.

The costs of poor birth outcomes to the United States in both human and fiscal terms are large and a continuing concern. Louisiana has among the worst birth outcomes in our nation, which include preterm and low birth weight births, and maternal and infant mortality. In response to these poor birth outcomes, the Louisiana Department of Health and Hospitals is implementing a statewide, multi-faceted Birth Outcomes Initiative at the level of the secretary. The Birth Outcomes Initiative aims to adopt evidence-based and best practices along the continuum of care for women and infants. Of particular importance is ending all non-medically indicated deliveries prior to 39 weeks, administration of the hormone 17-hydroxyprogesterone to eligible women for prematurity prevention, optimal behavioral health counseling and referral for reproductive aged women, and ensuring optimal health for women between pregnancies. Opportunities exist to improve outcomes for primary care and obstetrical providers. Louisiana is the first state to aim at improving birth outcomes with interventions before, during, and after pregnancy.

Community violence is associated with health-compromising behaviors (HCBs) and adverse general health and pregnancy outcomes. It is unknown whether these effects persist after adjusting for health behaviors. Retrospective cohort study of 36,637 pregnancies, 2005-2009, using birth certificate/hospital discharge databases. Community violence rate = (nonaccidental injuries/total injuries) × 100%. ZIP codes were categorized into levels (CVL) by quartiles (lowest, 1, to highest, 4). Outcomes included HCBs (tobacco, alcohol, or drugs), fetal death, preterm birth, and infant small-for-gestational-age (SGA). Covariates included HCBs and maternal characteristics. The CVL median (interquartile range) was 5.5% (3.8%-8.8%). As CVL increased, rates of HCBs (8% vs 13% vs 14% vs 16%), fetal death (4 vs 5 vs 6 vs 8/1000 pregnancies), preterm birth (8% vs 9% vs 11% vs 13%), and infant SGA (8% vs 10% vs 13% vs 16%) increased. The odds of preterm birth (CVL1 = 1.00 [reference] vs CVL2 = 1.00 [0.88-1.14] vs CVL3 = 1.10 [0.96-1.26] vs CVL4 = 1.25 [1.09-1.42]) and infant SGA (CVL2 = 1.03 [0.93-1.17] vs CVL3 = 1.15 [1.01-1.30] vs CVL4 = 1.21 [1.07-1.38]) increased, after controlling for HCB. CVL is associated with fetal death, preterm birth, and infant SGA, independent of HCB. These findings may support the role of violence-reduction programs in improving pregnancy health behaviors and outcomes.

Screening and treatment of sexually transmitted infections (STIs) in pregnancy represents an overlooked opportunity to improve the health outcomes of women and infants worldwide. Although Chlamydia trachomatis is the most common treatable bacterial STI, few countries have routine pregnancy screening and treatment programs. We reviewed the current literature surrounding Chlamydia trachomatis in pregnancy, particularly focusing on countries in sub-Saharan Africa and Asia. We discuss possible chlamydial adverse pregnancy and infant health outcomes (miscarriage, stillbirth, ectopic pregnancy, preterm birth, neonatal conjunctivitis, neonatal pneumonia, and other potential effects including HIV perinatal transmission) and review studies of chlamydial screening and treatment in pregnancy, while simultaneously highlighting research from resource-limited countries in sub-Saharan Africa and Asia.

Philadelphia-negative myeloproliferative neoplasms (MPNs) greatly increase the risk of maternal and fetal complications during pregnancy. Currently, international agreements regarding the management of these women are lacking. Our study aimed to assess the current management and outcomes of MPN pregnancies in a French cohort. We retrospectively analyzed 27 pregnancies in women with MPNs that were associated with a specific mutation. Nineteen pregnancies in nine women with essential thrombocythemia and eight pregnancies in five women with polycythemia vera were identified. Our study showed 70% live births, but only 30% uneventful pregnancies. Fetal complications were mainly early spontaneous abortions (22%), fetal growth restriction (15%), and premature delivery (15%). Maternal issues were divided between thrombosis (15%) and hemorrhages (11%). High rates of preeclampsia and hemolysis, elevated liver enzymes, and low platelet count syndrome (15%) were reported. Uterine artery Doppler was performed in 70% pregnancies. Abnormal Doppler results were found in 43% pregnancies. Pregnancies with high platelet counts and packed cell volume remaining static or increasing ended with fetal death and utero-placental dysfunction. According to expert consensus, most of the pregnancies (67%) could be stratified in the high risk group and had a bad obstetrical outcome, with 50% standard-risk pregnancies versus 22% high-risk pregnancies that were uneventful. Higher risk pregnancies were prescribed heparin and/or interferon α in 72%. The prognosis of these pregnancies remains very bad and may be improved by a more effective collaboration between specialists as well as a therapeutic intensification including heparin and interferon α.

To observe the changes of electrocardiogram (ECG) and pregnancy outcome of the late pregnancy women. Late pregnancy women were divided into two groups by age: over 35 group and under 35 group. The incidence of abnormal electrocardiogram was recorded when the patients were subjected to routine ECG examination. Then the pregnancy, delivery outcome and if there's low birth weight newborn were recorded later. The incidence of abnormal ECG in over 35 group was significantly higher than that in under 35 group (P < 0.05). And the incidence of ST segment changes, arrhythmia in the group of former was higher than that in the group of latter (P < 0.05). Among the different type of arrhythmia, the incidence of sinus bradycardia and ventricular premature beat in the group of former were higher than those in the group of latter (P < 0.05). But the incidence of sinus tachycardia in the former group was obviously lower than that in the latter group (P < 0.05). The incidence of pregnancy loss in over 35 with abnormal ECG group was significantly higher than that in under 35 with normal or abnormal ECG groups (P < 0.05). The incidence of premature birth in over 35 with abnormal ECG group was significantly higher than that in over 35 with normal ECG group (P < 0.05). The incidence of low body weight in over 35 with abnormal ECG group was significantly higher than that in under 35 with normal ECG group (P < 0.05). The late pregnancy women with the age of over 35 are more likely to have ECG abnormalities, such as arrhythmia, myocardial ischemia and so on. The older pregnant women with abnormal ECG easily suffer from pregnancy losing, premature birth and having a low birth weight baby.

The effects of exposure to marijuana in utero on fetal development are not clear. Given that the recent legislation on cannabis in the US is likely to result in increased use, there is a need to assess the effects of prenatal cannabis exposure on fetal development and pregnancy outcomes. The objective of this review is to assess the effects of prenatal exposure to cannabis on pregnancy outcomes (including maternal and child outcomes). Major databases will be searched from inception to the latest issue, with the aim of identifying studies that reported the effects of prenatal exposure to cannabis on fetal development and pregnancy outcomes. Two investigators will independently review all titles and abstracts to identify potential articles. Discrepancies will be resolved by repeated review, discussion and consensus. Study quality assessment will be undertaken, using standard protocols. To qualify for inclusion, studies must report at least one maternal or neonatal outcome post partum. Cross-sectional, case-control, cohort and randomised controlled trials published in English will be included. In order to rule out the effects of other drugs that may affect fetal development and pregnancy outcomes, studies will only be included if they report outcomes of prenatal exposure to cannabis while excluding other illicit substances. Data from eligible studies will be extracted, and data analysis will include a systematic review and critical appraisal of evidence, and meta-analysis if data permit. Meta-analysis will be conducted if three or more studies report comparable statistics on the same outcome. The review which will result from this protocol has not already been conducted. Preparation of the review will follow the procedures stated in this protocol, and will adhere to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Ethical approval of data will not be required since the review will use data that are already available in the

To study the factors associated with an adverse pregnancy outcome in women with systemic lupus erythematosus (SLE). SLE women from LUMINA of Hispanic, African American and Caucasian ethnicity were studied. Adverse pregnancy outcome was a miscarriage or abortion (<20 weeks), a stillbirth (> or = 20) and/or a moderate to severe preterm-baby (<34 weeks); good outcome was either a mild preterm-baby (> or = 34 weeks) or a full-term baby [C-section or vaginal delivery (38-42 weeks)]. Pregnancies occurring after SLE diagnosis (TD) were included; pregnancy outcome was the unit of analyses. The relationship between selected variables and pregnancy outcomes was examined by univariable and multivariable analyses. Adverse outcomes occurred in 63.7% of 102 pregnancies. In the univariable analyses, Texan Hispanic and African American ethnicities, fewer years of education, higher number of ACR criteria, renal involvement, glucocorticoid exposure and the maximum dose of glucocorticoids used prior to the pregnancy outcome were associated with an adverse pregnancy outcome. Renal involvement was independently associated with an adverse pregnancy outcome [Odds ratio (OR)=5.219 (95% Confidence Interval (CI) 1.416-19.239, p=0.0131] as were the maximum dose of glucocorticoids used prior to the pregnancy outcome (OR=1.028; CI:1.002-1.054; p=0.0315) and fewer years of education (OR=1.204; CI:1.006-1.472; p=0.0437). Ethnicity was not retained in the multivariable model. Renal involvement, the maximum dose of glucocorticoids used prior to pregnancy and fewer years of education were associated with adverse pregnancy outcomes. These data have implications for the management of women with lupus planning to become pregnant.

OBJECTIVE To determine whether prior spontaneous (SAB) or induced (IAB) abortions, or the inter-pregnancy interval are associated with subsequent adverse pregnancy outcomes in nulliparous women. METHODS We performed a secondary analysis of data collected from nulliparous women enrolled in a completed trial of vitamins C and E or placebo for preeclampsia prevention. Adjusted odds ratios for maternal and fetal outcomes were determined for nulliparous women with prior SABs and IABs as compared to primigravid participants. RESULTS Compared with primigravidas, women with one prior SAB were at increased risk for perinatal death (OR 1.5; 95% CI 1.1–2.3) in subsequent pregnancies. Two or more SABs were associated with an increased risk for spontaneous preterm birth (OR 2.6, 95% CI 1.7–4.0), preterm PROM (OR 2.9, 95% CI 1.6–5.3) and perinatal death (OR 2.8, 95% CI 1.5–5.3). Women with one previous IAB had higher rates of spontaneous preterm birth (OR 1.4, 95% CI 1.0–1.9) and preterm PROM (OR 2.0, 95% CI 1.4–3.0). An inter-pregnancy interval less than 6 months after SAB was not associated with adverse outcomes. CONCLUSION Nulliparous women with a history of SAB or IAB, especially multiple SABs, are at increased risk for adverse pregnancy outcomes. PMID:24347257

To compare pregnancy outcome and placental pathology in pregnancies complicated by fetal growth restriction (FGR) with and without preeclampsia. Labor, fetal/neonatal outcome, and placental pathology parameters from neonates with a birth weight below the 10 th percentile (FGR), born between 24 and 42 weeks of gestation, were reviewed. Results were compared between pregnancies complicated with preeclampsia (hypertensive FGR [H-FGR]) to those without preeclampsia (normotensive FGR [N-FGR]). Composite neonatal outcome, defined as 1 or more of early complication (respiratory distress, necrotizing enterocolitis, sepsis, transfusion, ventilation, seizure, hypoxic-ischemic encephalopathy, phototherapy, or death), Apgar score ≤ 7 at 5 minutes, and days of hospitalization, were compared between the groups. Placental lesions, classified as lesions related to maternal vascular supply, lesions consistent with fetal thrombo-occlusive disease and inflammatory lesions, maternal inflammatory response, and fetal inflammatory response, were also compared. Women in the H-FGR group (n = 72) were older, with higher body mass index (BMI) and higher rate of preterm labor (<34 weeks) than in the N-FGR group (n = 270), P < .001 for all. Composite neonatal outcome was worse in the H-FGR than in the N-FGR group, 50% versus 15.5%, P < .001. Higher rate of maternal placental vascular lesions was detected in H-FGR compared with N-FGR, 82% versus 57.7%, P < .001. Using a stepwise logistic regression model, maternal BMI (1.13 odds ratio [OR], confidence interval [CI] 1.035-1.227, P = .006) and neonatal birth weight (0.996 OR, CI 0.995-0.998, P < .001) were independently associated with worse neonatal outcome. Worse neonatal outcome and more maternal placental vascular lesions in pregnancy complicated by FGR with preeclampsia versus FGR without preeclampsia suggest different pathophysiology in these entities. © The Author(s) 2014.

Stroke occurring during pregnancy and the postnatal period is a rare but potentially catastrophic event. The aim of this study was to examine the incidence and outcomes of pregnancies complicated by maternal stroke in a single centre. This is a prospective study of over 35,000 consecutive pregnancies over a four-year period at the National Maternity Hospital in Dublin from 2004 to 2008; in addition we also retrospectively examined all cases of maternal mortality at our institution over a 50-year period from 1959 to 2009. We prospectively identified eight cases of strokes complicating pregnancy and the postnatal period giving an overall incidence of 22.34 per 100,000 pregnancies or 24.74 per 100,000 deliveries. There were no stroke-related mortalities during that time. Retrospective analysis of maternal mortality revealed 102 maternal deaths over a 50-year period, 19 (18.6%) of which were due to cerebrovascular accidents. In conclusion, strokes complicating pregnancy and the puerperium remain a rare event and though there appears to be evidence that the incidence is increasing, the associated maternal mortality appears to be falling.

Threatened abortion is the most common complication in the first half of pregnancy. Most of these pregnancies continue to term with or without treatment. Spontaneous abortion occurs in less than 30% of these women. Threatened abortion had been shown to be associated with increased incidence of antepartum haemorrhage, preterm labour and intra uterine growth retardation. This study was to asses the outcome of threatened abortion following treatment. This prospective study was carried out in Dhulikhel Hospital - Kathmandu University Hospital from January 2009 till May 2010. Total 70 cases of threatened abortion were selected, managed with complete bed rest till 48 hrs of cessation of bleeding, folic acid supplementation, uterine sedative, and hormonal treatment till 28 weeks of gestation. Ultrasonogram was performed for diagnosis and to detect the presence of subchorionic hematoma. Patients were followed up until spontaneous abortion or up to delivery of the fetus. The measures used for the analysis were maternal age, parity, gestational age at the time of presentation, previous abortions, presence of subchorionic hematoma, complete abortion, continuation of pregnancy, antepartum hemorrhage, intrauterine growth retardation and intrauterine death of fetus. Out of 70 cases subchorionic haematoma was found in 30 (42.9%) cases. There were 12 (17.1%) patients who spontaneously aborted after diagnosis of threatened abortion during hospital stay, 5 (7.1%) aborted on subsequent visits while 53 (75.8%) continued pregnancy till term. Among those who continued pregnancy intrauterine growth retardation was seen in 7 (13.2%), antepartum hemorrhage in 4 (7.5%), preterm premature rupture of membrane in 3 (5.66%) and IUD in 3 (5.66%). Spontaneous abortion was found more in cases with subchorionic hematoma of size more than 20 cm2. In cases of threatened abortion with or without the presence of subchorionic hematoma, prognostic outcome is better following treatment with bed rest

Although there is increasing evidence to suggest an association between periodontal disease and adverse pregnancy outcomes, the issue remains controversial. This study tested the hypothesis that periodontal disease is a risk indicator for preterm delivery of low-birthweight infants. The study sample comprised 443 pregnant women with a mean (± standard deviation) age of 24.13 (±5.30) years. At first visit, maternal oral health status was assessed by the measurement of probing pocket depth and clinical attachment loss, and periodontal status was graded as absent, mild, moderate or severe. An association was sought between pregnancy outcomes and maternal periodontal status. While controlling for other factors, significant associations were found between pregnancy outcomes and maternal periodontal index scores. This study provides further evidence that periodontal disease is a risk indicator for adverse pregnancy outcomes. © 2016 FDI World Dental Federation.

Objective It is unclear whether the stimulated state of the ovaries as part of ART results in an increased vulnerability to the effects of methotrexate. The objective of this study was to assess ovarian reserve following methotrexate treatment for ectopic pregnancy or pregnancy of unknown location after ART. Design Retrospective cohort study. Setting Large ART practice. Patients Methotrexate or surgery following ART. Interventions None. Main Outcome Measures Follicle stimulating hormone (FSH), antral follicle count (AFC), and oocyte yield were compared between subjects treated with methotrexate and surgery. Secondary outcomes were clinical pregnancy and live birth. Results There were 153 patients in the methotrexate group and 36 patients in the surgery group. Neither group demonstrated differences in ovarian reserve or oocyte yield comparing before and after treatment values. The change in ovarian reserve and oocyte yield after treatment were similar between the two groups. The number of doses of methotrexate was not correlated with changes in ovarian reserve, indicating no dose-dependent effect. Time between treatment and repeat ART was not correlated with outcomes. Live birth in subsequent cycles was similar in the two groups. Conclusions Ovarian reserve and subsequent ART cycle outcomes were reassuring following methotrexate and surgical management of ectopic pregnancy. An adverse impact of methotrexate was not detected in this large fertility cohort as has been previously described. PMID:24269042

Type 1 diabetes mellitus in pregnant women is associated with an increased risk of congenital malformations, obstetric complications, neonatal morbidity, and mortality. Our aim was to evaluate which factors from the first trimester of pregnancy have a significant impact on the pregnancy outcomes of women with type 1 diabetes. We included 94 pregnant women with type 1 diabetes in this study. In these patients, we analyzed the influence of several diabetes-related parameters on the pregnancy outcome. We compared the parameters between two cohorts: those with successful pregnancies and those with adverse pregnancy outcomes, defined as spontaneous abortion or congenital malformations. The influence of several factors on the pregnancy outcome was assessed using multivariate and univariate logistic regressions. The prevalence of adverse pregnancy outcomes was 28.7%, and was associated with poorer glycemic control (p <0.001), lower frequency of daily self-monitoring tests (p <0.001), smoking status (p <0.001), alcohol consumption (p <0.001), increased prevalence of chronic complications of diabetes, and the presence of ketosis. However, the adverse outcomes were not significantly associated with age, duration of diabetes, presence of thyroid disease, or body mass index. Furthermore, planned pregnancy was found to be a significant protective factor (odds ratio, 0.15; p <0.001). These results indicate that by carefully planning the pregnancy, ensuring optimal glycemic control, and eliminating habitual risk factors, the fetal risk in pregnancies among women with type 1 diabetes may decrease to a value similar to that noted in women without diabetes.

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

The Impact of Uterine Radiation on Subsequent Fertility and Pregnancy Outcomes

2014-01-01

Future fertility is of paramount importance to younger cancer survivors. Advances in assisted reproductive technology mean that young women treated with radiation involving the uterus may require clinical guidance regarding whether to attempt a pregnancy themselves. We performed a review of the literature regarding radiation involving uterus (total body irradiation (TBI) and pelvic radiation), fertility, and pregnancy outcomes to come up with a recommendation for our patients. Limited evidence suggests lower fecundity and an increased incidence of pregnancy complications after uterine radiation. Higher radiation doses and direct uterine radiation both significantly increase the risk of an adverse pregnancy outcome. Uterine radiation doses of <4 Gy do not appear to impair uterine function. Adult TBI data (usually 12 Gy) suggest pregnancy is possible but with lower fecundity and more complications. Although there is no clear data indicating the dose of radiation to the uterus, above which a pregnancy would not be sustainable, we suggest patients receiving >45 Gy during adulthood and >25 Gy in childhood be counselled to avoid attempting pregnancy. There is preliminary evidence that menopausal hormone therapy and a combination of pentoxifylline and tocopherol may improve uterine function following irradiation. PMID:25165706

Approximately 10% of women engage in resistance training during pregnancy; however there is limited research on this activity. The purpose of this study was to examine associations between resistance training and adverse outcomes. Women completed an online survey and recalled their exercise habits during each trimester of their most recent pregnancy within the previous 5 years. Women also reported pregnancy and birth outcomes. Participants were then categorized into 3 groups based on leisure-time exercise: 1) Resistance + aerobic training (RTAE), 2) Aerobic exercise only (AE), and 3) no exercise (NE). 284 women completed the survey. Women in the RTAE group resistance trained on average 2.9 days/ week for 27.3 minutes/session. The prevalences of hypertensive disorders (HD) and gestational diabetes mellitus (GDM) were significantly lower in the RTAE group when compared with the grouping of AE + NE women. Prepregnancy body mass index (BMI) was the strongest factor related to both GDM and HD. There was no difference in the risk of preterm labor, mode of delivery, or gestational age at delivery by exercise status. Our results suggest that women can safely engage in aerobic exercise and resistance training for muscular endurance 3 days/week for 30 minutes throughout gestation.

Vitamin D deficiency is common during pregnancy and higher in Hispanic as compared with non-Hispanic white women. However, the association between vitamin D deficiency and adverse pregnancy outcomes remains unclear and may vary across ethnic groups, in part because of genetic variation in the metabolism of vitamin D. Few studies have included Hispanic women. Therefore, we investigated this association among 237 participants in the Behaviors Affecting Baby and You Study, a randomised trial of an exercise intervention among ethnically diverse prenatal care patients in Massachusetts. Baseline serum 25-hydroxyvitamin D (25(OH)D) was measured at 15·2 (sd 4·7) weeks’ gestation. Information on adverse pregnancy outcomes was abstracted from medical records. Mean 25(OH)D was 30·4 (sd 12·0) ng/ml; 53·2 % of participants had insufficient (<30 ng/ml) and 20·7 % had deficient (<20 ng/ml) 25(OH)D levels. After adjusting for month of blood draw, gestational age at blood draw, gestational age at delivery, age, BMI and Hispanic ethnicity, women with insufficient and deficient vitamin D had infants with birth weights 139·74 (se 69·16) g (P=0·045) and 175·52 (se 89·45) g (P=0·051) lower compared with women with sufficient vitamin D levels (≥30 ng/ml). Each 1 ng/ml increase in 25(OH)D was associated with an increased risk for gestational diabetes mellitus among Hispanic women only (relative risk 1·07; 95 % CI 1·03, 1·11) in multivariable analysis. We did not observe statistically significant associations between maternal vitamin D status and other pregnancy outcomes. Our findings provide further support for an adverse impact of vitamin D deficiency on birth weight in Hispanic women. PMID:26507186

The mechanisms involved in bleeding in cases of placenta previa (PP) and the effect on pregnancy outcome is unclear. We aimed to compare pregnancy outcome and placental histopathology in pregnancies complicated with symptomatic (bleeding) vs. non-symptomatic PP, and to study the effects of the co-existence of histopathological retro-placental hemorrhage (RPH) in cases of symptomatic PP on neonatal and maternal outcomes. Labor and maternal characteristics, neonatal outcome and placental histopathology lesions of pregnancies with PP, delivered between 24 and 42weeks, during 2009-2015, were reviewed. Results were compared between PP who had elective cesarean delivery (CD) (previa group) and PP with bleeding necessitating emergent CD (symptomatic previa group). Placental lesions were classified to lesions consistent with maternal malperfusion or fetal thrombo-occlusive disease (vascular and villous changes), and inflammatory lesions. Compared to the previa group (n=63), the symptomatic previa group (n=74) was characterized by older patients (p<0.001), higher rate of smokers (p=0.005), thrombophilia (p=0.038), and preterm deliveries (p<0.001). Placentas within the symptomatic previa group were smaller, with higher rates of weight<10th% (p=0.02), RPH (p<0.001) and villous changes related to maternal malperfusion (p=0.023). As compared to symptomatic PP without RPH, co-existence of RPH was associated with higher rate of adverse neonatal outcome (p<0.001) and maternal blood transfusion (p=0.02). On multivariate regression analysis, composite adverse neonatal outcome was found to be dependent on coexisting RPH (OR=2.8, 95%CI 1.2-11.7, p=0.03), and low gestational age (OR=3.1, 95%CI 1.6-4.9, p=0.02). Symptomatic placenta previa is associated with increased placental malperfusion lesions suggesting an association of maternal malperfusion with abnormal placental separation. The coexisting finding of RPH with symptomatic placenta previa can be seen as a marker for more

To review flight regulations and gestational complications associated with air travel in pregnant passengers, flight attendants, and aviators. A literature search was undertaken on the relationship of air travel and spontaneous pregnancy losses, intrauterine fetal demise (IUFD), birth weight<10th percentile, preterm delivery, and neonatal intensive care unit admissions. The literature search identified 128 abstracts, of which 9 evaluated air travel and pregnancy outcomes. The risk of a pregnancy loss (spontaneous abortion or IUFD) was greater in flight attendants than controls (odds ratio [OR]: 1.62, 95% confidence interval [CI]: 1.29, 2.04). The risk of preterm birth<37 weeks was greater in passengers than controls (OR: 1.44, 95% CI: 1.07, 1.93). However, the risk of preeclampsia (OR: 0.86, 95% CI: 0.58, 1.27), neonatal intensive care unit admissions (OR: 1.19, 95% CI: 0.78, 1.82), or birth weight<10th percentile (OR: 1.25, 95% CI: 0.62, 2.48) was not increased. Flight attendants did not have an increased risk of preterm birth compared to controls (OR: 1.37, 95% CI: 0.85, 2.22) or delivering infants with birth weight<10th percentile (OR: 1.57, 95% CI: 0.68, 3.74). The risks of spontaneous abortions and other adverse pregnancy outcomes have been poorly studied in a limited number of investigations. An analysis of the available information suggests a greater risk of spontaneous abortions or IUFD in flight attendants, and a greater risk of preterm birth<37 weeks in air passengers. However, the literature on which these findings are based is generally not of high methodologic quality.

Adverse pregnancy outcomes entail a large health burden for the mother and offspring; a part of it might be avoided by better understanding the role of environmental factors in their etiology. Our aims were to review the assessment tools to characterize fecundity troubles and pregnancy-related outcomes in human populations and their sensitivity to environmental factors. For each outcome, we reviewed the possible study designs, main sources of bias, and their suggested cures. In terms of study design, for most pregnancy outcomes, cohorts with recruitment early during or even before pregnancy allow efficient characterization of pregnancy-related events, time-varying confounders, and in utero exposures that may impact birth outcomes and child health. Studies on congenital anomalies require specific designs, assessment of anomalies in medical pregnancy terminations, and, for congenital anomalies diagnosed postnatally, follow-up during several months after birth. Statistical analyses should take into account environmental exposures during the relevant time windows; survival models are an appropriate approach for fecundity, fetal loss, and gestational duration/preterm delivery. Analysis of gestational duration could distinguish pregnancies according to delivery induction (and possibly pregnancy-related conditions). In conclusion, careful design and analysis are required to better characterize environmental effects on human reproduction. PMID:24363355

To investigate the risk of adverse pregnancy outcomes among adolescents in 29 countries. Secondary analysis using facility-based cross-sectional data of the World Health Organization Multicountry Survey on Maternal and Newborn Health. Twenty-nine countries in Africa, Latin America, Asia and the Middle East. Women admitted for delivery in 359 health facilities during 2-4 months between 2010 and 2011. Multilevel logistic regression models were used to estimate the association between young maternal age and adverse pregnancy outcomes. Risk of adverse pregnancy outcomes among adolescent mothers. A total of 124 446 mothers aged ≤24 years and their infants were analysed. Compared with mothers aged 20-24 years, adolescent mothers aged 10-19 years had higher risks of eclampsia, puerperal endometritis, systemic infections, low birthweight, preterm delivery and severe neonatal conditions. The increased risk of intra-hospital early neonatal death among infants born to adolescent mothers was reduced and statistically insignificant after adjustment for gestational age and birthweight, in addition to maternal characteristics, mode of delivery and congenital malformation. The coverage of prophylactic uterotonics, prophylactic antibiotics for caesarean section and antenatal corticosteroids for preterm delivery at 26-34 weeks was significantly lower among adolescent mothers. Adolescent pregnancy was associated with higher risks of adverse pregnancy outcomes. Pregnancy prevention strategies and the improvement of healthcare interventions are crucial to reduce adverse pregnancy outcomes among adolescent women in low- and middle-income countries. © 2014 RCOG The World Health Organization retains copyright and all other rights in the manuscript of this article as submitted for publication.

Mood stabilizers in pregnancy and child developmental outcomes: A systematic review.

Research suggests that maintaining treatment during pregnancy for women with bipolar affective disorder reduces the risk of relapse. However, one of the key questions for women and clinicians during pregnancy is whether there are implications of exposure to mood stabilizers for longer term child development. Despite these concerns, there are few recent systematic reviews comparing the impact on child developmental outcomes for individual mood-stabilizing agents to inform clinical decisions. To examine the strengths and limitations of the existing data on child developmental outcomes following prenatal exposure to mood stabilizers and to explore whether there are any differences between agents for detrimental effects on child development. Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, a rigorous systematic search was carried out of four electronic databases from their respective years of inception to September 2016 to identify studies which examined the effects of mood stabilizers including sodium valproate, carbamazepine, lamotrigine, lithium and second-generation antipsychotics on child developmental outcomes. We identified 15 studies for critical review. Of these, 10 examined antiepileptic drugs, 2 studied lithium and 3 studied second-generation antipsychotics. The most consistent finding was a dose-response relationship for valproate with higher doses associated with poorer global cognitive abilities compared to other antiepileptic drugs. The limited data available for lithium found no adverse neurodevelopmental outcomes. The limited second-generation antipsychotic studies included a report of a transient early neurodevelopmental delay which resolved by 12 months of age. This review found higher neurodevelopmental risk with valproate. While the existing data on lithium and second-generation antipsychotics are reassuring, these data are both limited and lower quality, indicating that further research is required. The

The maternal microbiome is recognized as a key determinant of a range of important maternal and child health outcomes, and together with perinatal factors influences the infant microbiome. This manuscript provides a summary review of research investigating: (1) the role of the maternal microbiome in pregnancy outcomes known to adversely influence neonatal and infant health, including preterm birth, cardiometabolic complications of pregnancy such as preeclampsia and gestational diabetes, and excessive gestational weight gain; (2) factors with an established link to adverse pregnancy outcomes that are known to influence the composition of the maternal microbiome; and (3) strategies for promoting a healthy maternal microbiome, recognizing that much more research is needed in this area.

To describe the degree of perceived fertility control and associated likelihood of unintended pregnancy and poor pregnancy outcomes among women who report intimate partner violence. Cross-sectional cohort study design. Five domestic violence shelters and one district attorney's office in a large urban metropolis in the United States. A total of 282 women who reported intimate partner violence and reached out for the first time to a shelter or district attorney's office for assistance. This 7-year prospective longitudinal study began in 2011. Participants in the overarching study are being interviewed every 4 months. During the 32-month interview period, participants responded to a one-time, investigator-developed, fertility control questionnaire in addition to the ongoing repeated measures. Almost one third (29%) of the participants reported at least one unintended pregnancy attributed to their abusers' refusal to use birth control, and 14.3% of the participants reported at least one unintended pregnancy as a result of their abusers' refusal to allow them to use birth control. Participants were 28 times more likely to have abuse-induced miscarriages if their pregnancies resulted because their abusers did not use birth control (OR = 28.70, p < .05). Finally, participants were 8 times more likely to report premature births if they were abused because of their use of birth control (OR = 8.340, p < .05). Women in abusive relationships reported compromised fertility control associated with abuse and increased risk for unintended pregnancy as well as the adverse pregnancy outcomes of premature birth and miscarriage.

Objective The relationship between pregnancy outcomes and fetal gender is well reported from different areas in the world, but not from Africa. In this study, we try to understand whether the recorded phenomenon of association of adverse pregnancy outcomes with a male fetus applies to our population. Materials and methods A total of 29,140 patient records from 2009 and 2010 were retrieved from Aljalaa Maternity Hospital, Tripoli, Libya. Analysis was carried out to find the correlation between fetal gender and different pregnancy outcomes. Results A male fetus was associated with an increased incidence of gestational diabetes mellitus (odds risk 1.4), preterm delivery (6.7% for males, 5.5% for females, odds risk 1.24), cesarean section (23.9% for males, 20% for females, odds risk 1.25), and instrumental vaginal delivery (4.4% for males, 3.1% for females, odds risk 1.48), p<0.005. Preeclampsia was more frequent among preterm females and postterm males, p<0.005. It was also more frequent in male-bearing primigravids, p<0.01. Conclusion We confirm the existence of an adverse effect of a male fetus on pregnancy and labor in our population. We recommend further research to understand the mechanisms and clinical implications of this phenomenon. PMID:23308081

The aim of this study is to analyze the effect of 100 mg/d regular oral intake of aspirin during pregnancy on high-risk pregnancy-induced hypertension syndrome patients. We consecutively selected 98 cases high-risk pregnancy-induced hypertension syndrome patients. After obtaining the informed consent of the patients, we randomly divided the patients into aspirin group (50 cases) and placebo group (48 cases). The oral intake of aspirin lasted from the final diagnosis of pregnancy to antepartum time, and was taken before sleep. The bleeding index was closely detected and we stop taking aspirin when necessary. The comparison of clinical outcome showed that the incidents of pregnancy-induced hypertension syndrome, pre-eclampsia and eclampsia of aspirin group were significantly lower than that of the placebo group (p<0.05). Comparing the complications of fetus perinatal period, the difference was not statistically significant (p>0.05). 100 mg/d regular oral intake of aspirin during pregnancy is safe, effective and worthy of generalization to high-risk pregnancy-induced hypertension syndrome patients.

Stroke occurring during pregnancy and the postnatal period is a rare but potentially catastrophic event. The aim of this study was to examine the incidence and outcomes of pregnancies complicated by maternal stroke in a single centre. This is a prospective study of over 35,000 consecutive pregnancies over a four-year period at the National Maternity Hospital in Dublin from 2004 to 2008; in addition we also retrospectively examined all cases of maternal mortality at our institution over a 50-year period from 1959 to 2009. We prospectively identified eight cases of strokes complicating pregnancy and the postnatal period giving an overall incidence of 22.34 per 100,000 pregnancies or 24.74 per 100,000 deliveries. There were no stroke-related mortalities during that time. Retrospective analysis of maternal mortality revealed 102 maternal deaths over a 50-year period, 19 (18.6%) of which were due to cerebrovascular accidents. In conclusion, strokes complicating pregnancy and the puerperium remain a rare event and though there appears to be evidence that the incidence is increasing, the associated maternal mortality appears to be falling.

Women, work and pregnancy outcome.

In developing countries, 1/3 of infants are born weighing less than 2500 grams. A study conducted in Ethiopia among women consuming about 1600 kcal/day, those who were very physically active during pregnancy bore smaller babies, and gained less weight during pregnancy, than those who were not so active. Average birth weight was 3068 grams for the 1st group, 3270 grams for the less active. The active group of women gained an average of 6.5 kilograms, and the less active 9.2 kilograms. Women who did not engage in heavy work during pregnancy, although they were undernourished, apparently did not bear growth-retarded babies. Indirect evidence for the effect of physical activity on pregnancy outcome comes from studies conducted in Taiwan, and the Gambia. These studies, and others from Malawi, Burkina Faso, and Kenya have shown that women's energy expenditures vary greatly with the agricultural season. Daily housekeeping tasks, however, also consume a lot of women's energy. Technologies that allow women to reduce energy expenditure can have beneficial effects, if they do not simultaneously reduce their incomes. For instance, programs improving water or fuel availability, or reducing fuel needs, reduce women's energy expenditures. Food processing mills can help too if women have access to them, and are thus not in danger of being displaced from their jobs and losing necessary income. Examples of technology improving women's tasks are pedal drying machines for nice in Bangladesh, using a greater and pressing machine to prepare gari in Ghana; but growing thicker rice stalks in Indonesia displaced women workers and reduced income.

Objective The aim of this study was to examine the mutual effect of pre-pregnancy body mass index (BMI), waist circumference (WC) and gestational weight gain (GWG) on obesity-related adverse pregnancy outcomes. Methods This birth cohort study was conducted in three Streets in Changsha, China, including a total of 976 mother-child pairs. All data was collected within 15 days after deliveries from a self-administered questionnaire, maternal health manual and perinatal health care information system. Multivariate logistic regression models were conducted to estimate the effects of maternal pre-pregnancy BMI, WC and GWG on obesity-related adverse pregnancy outcomes including gestational diabetes mellitus (GDM), primary cesarean section (P-CS), large for gestational age (LGA) and composite outcome (one or more adverse pregnancy outcomes) Results After controlling for all confounders, both maternal pre-pregnancy overweight/obesity and central adiposity contributed to increased risks of GDM [ORs 95% CIs = 2.19 (1.02–4.76) and 2.26 (1.11–4.60), respectively], P-CS [ORs 95% CIs = 1.66 (1.05–2.65) and 1.71 (1.11–2.63), respectively], LGA [ORs 95% CIs = 1.93 (1.07–3.50) and 2.14 (1.21–3.75), respectively] and composite outcome [ORs 95% CIs = 1.82 (1.15–2.87) and 1.98 (1.30–3.01), respectively] compared with mothers with normal pre-pregnancy weight and normal WC. Excessive GWG was found to be associated with an increased risk of LGA [OR 95% CI = 1.74 (1.05–2.89)], but was not significantly related to higher risks of GDM, P-CS and composite outcome [ORs 95% CIs = 0.90 (0.47–1.72), 1.08 (0.77–1.52), and 1.30 (0.94–1.79), respectively]. In terms of the joint effect of maternal pregestational BMI and WC on obesity-related composite outcome, mothers with both pre-pregnancy overweight and central adiposity had the highest risk of composite outcome [OR 95% CI = 3.96 (2.40–6.54)], compared with mothers without pre-pregnancy overweight or central adiposity

Low levels of maternal serum pregnancy associated plasma protein-A (PAPP-A) have been linked to chromosome anomalies such as trisomy 21, 13 and 18, triploidy and sex chromosome aneuploidy. Low levels of PAPP-A have also been implicated in spontaneous miscarriage. The purpose of this study was to evaluate whether low levels of first trimester PAPP-A are predictive of other adverse pregnancy outcomes. The study included patients with singleton pregnancies who underwent combined first trimester screening using nuchal translucency (NT) and maternal serum free beta-human chorionic gonadotrophin (free beta-hCG) and PAPP-A at 10-13 weeks' gestation. Patients with chromosome aberrations or fetal anomalies were excluded. Serum marker levels were expressed as gestational age-specific multiples of the median (MoMs). The incidences of various adverse pregnancy outcomes (spontaneous preterm labor, fetal growth restriction (FGR), proteinuric and non-proteinuric pregnancy induced hypertension (PIH), intrauterine fetal demise, oligohydramnios, spontaneous miscarriage and placental abruption) were evaluated, according to maternal PAPP-A MoM levels. Of the 1622 patients in the study, pregnancy complications were observed in 184 (11.3%). Patients with PAPP-A < or =0.25 MoM had significantly higher rates of FGR (RR = 3.12), proteinuric PIH (RR = 6.09), spontaneous miscarriage (RR = 8.76). No statistically significant differences were noted for other adverse outcomes evaluated Women with PAPP-A < or =0.50 MoM also had significantly higher rates of FGR (RR = 3.30) and spontaneous miscarriage (RR = 3.78). We conclude that decreased levels of first trimester maternal serum PAPP-A are predictive not only of chromosome anomalies but also of adverse pregnancy outcome.

The present study was conducted with the aim to find out the effect of threatened abortion in the current pregnancy on the subsequent perinatal outcome and follow the growth pattern of the fetuses of such complicated pregnancies. The study group consisted of 55 women with threatened abortion and 55 women with normal pregnancies formed the control group. Most of the patients presented at 6-12 weeks' gestation. The fetal growth was monitored by both clinical as well as ultrasound (USG) parameters. The mean growth rates were almost identical throughout gestation. The mean values of each parameter of the study group were found lying with 95% confidence limit values of their control group. The apparent increased incidence of low lying placenta in early pregnancy probably contributed to threatened abortion. There was no significant difference in preterm delivery, low birth-weight and overall perinatal outcome.

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

Recurrent pregnancy loss (RPL) is defined by two or more failed clinical pregnancies. Three to four percent of the couples with RPL have chromosomal aberrations (CA) in at least one partner. The parent's structural chromosomal abnormalities may cause an unbalanced karyotype in the conceptus which could lead to implantation failure, early or late pregnancy loss, or delivery of a child with severe physical and/or mental disabilities. To compare live birth rates of couples with CA to couples with normal karyotypes and to investigate medical and obstetric characteristics and pregnancy outcomes of couples with CA and RPL who attend an RPL clinic at a tertiary hospital. A retrospective cohort study, including 349 patients with two or more consecutive pregnancy losses. The study group consisted of 52 patients with CA, and the control group consisted of 297 couples with normal karyotype. All patients were evaluated and treated in the RPL clinic at Soroka University Medical Center and had at least one subsequent spontaneous pregnancy. The demographic and clinical characteristics were not found to be statistically different between the two groups. The group of carriers of CA had 28/52 (53.8%) live births in their index pregnancy vs. the normal 202/297 (68%) (P=0.067, CI 95%) in the control group. No statistically significant etiology was found between the study group and the control group. A statistically significant difference in live birth rates was found when comparing the total amount of pregnancies [index pregnancy (IP)+post index pregnancy (PIP)] between the study group and the control group (54.16% vs. 67.82%, respectively, P=0.0328). Patients with RPL and CA who have spontaneous pregnancies, have a good prognosis (63.4%) of a successful pregnancy with at least one of the pregnancies (index or post index) resulting in a live birth.

Previous studies have reported mortality rates of up to 56% associated with pregnancy in pulmonary arterial hypertension (PAH) but the management of this disease has changed considerably in recent years. We compiled a multinational, prospective registry to examine the contemporary outcome of pregnancies in patients with PAH. During a 3-yr period, the 13 participating centres reported 26 pregnancies. Three (12%) females died and one (4%) developed right heart failure requiring urgent heart-lung transplantation. There were eight abortions; two spontaneous and six induced. 16 (62%) pregnancies were successful, i.e. the females delivered healthy babies without complications. These females had well controlled PAH (pulmonary vascular resistance (PVR) 500 ± 352 dyn·s·cm(-5)); eight of them were long-term responders to calcium channel blockers. In contrast, the females who died or required transplantation had poorly controlled PAH (PVR 1,667 ± 209 dyn·s·cm(-5)). Pregnancy remains associated with a substantial mortality rate in PAH. However, our results indicate that the outcome of pregnancy in PAH has improved, at least when PAH is well controlled, and particularly in long-term responders to calcium channel blockers. These data must be confirmed by larger series before the general recommendation to avoid pregnancy in all patients with PAH is reconsidered.

With the increasing prevalence of chronic kidney disease (CKD) worldwide, the number of pregnant women with various degrees of renal dysfunction is expected to increase. There is a bidirectional relation between CKD and pregnancy in which renal dysfunction negatively affects pregnancy outcomes, and the pregnancy can have a deleterious impact on various aspects of kidney disease. It has been shown that even mild renal dysfunction can increase considerably the risk of adverse maternal and fetal outcomes. Moreover, data suggest that a history of recovery from acute kidney injury is associated with adverse pregnancy outcomes. In addition to kidney dysfunction, maternal hypertension and proteinuria predispose women to negative outcomes and are important factors to consider in preconception counseling and the process of risk stratification. In this review, we provide an overview of the physiologic renal changes during pregnancy as well as available data regarding CKD and pregnancy outcomes. We also highlight the important management strategies in women with certain selected renal conditions that are seen commonly during the childbearing years. We call for future research on underexplored areas such as the concept of renal functional reserve to develop a potential clinical tool for prognostication and risk stratification of women at higher risk for complications during pregnancy.

Oral contraceptives (OC) and pregnancy are known to have an influence on the risk of onset of rheumatoid arthritis (RA). Pregnancy itself has beneficial effects on the activity of the disease, with relapses post partum. It is not known, however, whether OC and pregnancies influence the ultimate outcome of RA. To explore whether OC use and pregnancies influence the 12 year outcome in RA as measured by radiological damage and disability. In a prospective inception cohort of 132 female patients with recent RA according to the 1987 American College of Rheumatology criteria-a cohort initially gathered to study the association between hormonal factors and the onset of RA-outcome was assessed in a follow up after 12 years. The outcome was evaluated in 112 (85%) women by the radiological damage of hands and feet as measured with the Sharp score modification van der Heijde (SHS), the damage of the large joints measured with the Larsen score (LS) of large joints (0-60), and the disability measured with the Health Assessment Questionnaire (HAQ). The median values of each outcome variable were calculated for several subgroups of patients stratified for OC use and pregnancies before and after onset of the disease and the tertiles of the total number of months of OC use and of pregnancies. The association of OC use and pregnancies before and after onset of the disease with the outcome variables was calculated using Spearman's rank correlation (r(s)). The combined influence of OC use and pregnancies on the SHS, LS, and HAQ at 12 years was estimated using ordinal polytomous logistic regression. The median values of the SHS, LS, and HAQ showed a trend towards less radiological joint damage and less disability in women with long term OC use and multiple pregnancies. This difference, however, was not significant, except for the HAQ score in women with three or more pregnancies in life. There was no association between pregnancies, however defined, and any parameter of RA outcome

In this study, we aimed to determine the provincial population-based seroprevalence in pregnant women and to further explore the association of maternal CMV infection status and adverse pregnancy/neonatal/growth outcomes in Jiangsu, China. In this case-control study, the sera from 527 pregnant women with adverse pregnancy/neonatal outcomes and 496 mothers of healthy infants in Jiangsu Province, collected at gestation age of 15-20 weeks, were tested for anti-CMV IgG, IgM and IgG avidity. Adverse pregnancy/neonatal outcomes were identified based on pregnancy/neonatal outcomes. The overall seroprevalence of anti-CMV IgG was 98.7%, with 99.4% and 98.0% in the case and control groups, respectively (P = 0.039). The prevalence of anti-CMV IgG+/IgM+, was higher in the case group than that in the control group (3.8% vs. 1.6%, P = 0.033). Anti-CMV IgG avidity assay showed that none in the control group were primarily infected, but five (0.9%) in the case group underwent primary infection (P = 0.084); all five infants of these women presented severe adverse neonatal/growth outcomes. Exact logistic regression analysis showed that anti-CMV IgG+/IgM+ was associated with adverse pregnancy/neonatal/growth outcomes (aOR = 2.44, 95% CI 1.01-6.48, P = 0.047). Maternal low education level and prior abnormal pregnancies also were risk factors for adverse pregnancy/neonatal outcomes. In populations with very high prevalence of latent CMV infection, active maternal CMV infection during pregnancy might be a risk factor for adverse pregnancy/neonatal outcomes.

Aim Maternal obesity is associated with complications and adverse outcomes during the labor and delivery process. In pregnant women with a healthy body weight, maternal physical activity during pregnancy is associated with better obstetric outcomes; however, the effect of maternal physical activity during pregnancy on obstetric outcomes in obese women is not known. The purpose of the study was to determine the influence of self-reported physical activity levels on obstetric outcomes in pregnant obese women. Methods A retrospective chart review was performed on 48 active obese women and 48 inactive obese women (N=96) who received prenatal care and delivered at the medical center during the past five years. Obstetric and neonatal outcomes were compared between the active and inactive groups. Results Obese women who were active during pregnancy spent less total time in labor (13.4 hours vs. 19.2 hours, p=0.048) and were less likely to request an epidural (92% vs. 100%, p=0.04). When stratified by parity, active multiparous women spent significantly less total time in labor compared to inactive multiparous (6.2 hours vs. 16.7 hours, p=0.018). There were no statistical differences between groups in rates of cesarean deliveries or neonatal outcomes. Conclusion Maternal physical activity during pregnancy appears to improve obstetric outcomes in obese women, and this improvement may be more pronounced among multiparous women. Our finding is of particular importance as pregnant obese women are at higher risk for adverse and delivery outcomes. PMID:26564274

Malnutrition and weight loss are common features of patients with inflammatory bowel disease (IBD). To explore the impact of inadequate gestational weight gain (GWG) on adverse outcomes among IBD mothers in the prospective US pregnancy in Inflammatory Bowel Disease and Neonatal Outcomes (PIANO) cohort. The PIANO cohort comprises 559 and 363 pregnant mothers with Crohn's disease (CD) and ulcerative colitis (UC), respectively, enrolled between 2006 and 2014. The mothers were followed during and after pregnancy to ascertain medication, measurement of disease activity and complications during pregnancy and at delivery. Inadequate GWG was based on US Institute of Medicine recommendations. The associations between inadequate GWG and adverse pregnancy outcomes in maternal IBD were analyzed, adjusted for diabetes, hypertension, smoking, maternal age, education, and disease activity. Maternal CD and UC with inadequate GWG had a 2.5-fold increased risk of preterm birth (OR 2.5, CI 1.3, 4.9 and OR 2.5, CI 1.2, 5.6). Furthermore, an increased risk of intrauterine growth restriction and a trend for small for gestational age were demonstrated in CD but not in UC (OR 3.3, CI 1.1, 10.0, OR 4.5, CI 0.8, 24.3, p = 0.08). Flares increased risk of inadequate GWG (OR 1.6, CI 1.2, 2.3, p = 0.002) but did not change the associations between inadequate GWG and adverse pregnancy outcomes in our models. The US PIANO cohort demonstrated that inadequate GWG was a strong independent predictor of adverse pregnancy outcomes in IBD mothers.

Chronic arsenic exposure is a public health concern in many parts of the world, with elevated concentrations in groundwater posing a threat to millions of people. Arsenic is associated with various cancers and an array of chronic diseases; however, the relationship with adverse pregnancy outcomes and child mortality is less established. We evaluated associations between individual-level prenatal arsenic exposure with adverse pregnancy outcomes and child mortality in a pregnancy study among 498 women nested in a larger population-based cohort in rural Bangladesh. Creatinine-adjusted urinary total arsenic concentration, a comprehensive measure of exposure from water, food, and air sources, reflective of the prenatal period was available for participants. Self-reported pregnancy outcomes (livebirth, stillbirth, spontaneous/elective abortion) were ascertained. Generalized estimating equations, accounting for multiple pregnancies of participants, were used to estimate odds ratios and 95% confidence intervals in relation to adverse pregnancy outcomes. Vital status of livebirths was subsequently ascertained through November 2015. Cox proportional hazards models were used to estimate hazard ratios and 95% confidence intervals in relation to child mortality. We observed a significant association between prenatal arsenic exposure and the risk of stillbirth (greater than median; adjusted OR = 2.50; 95% CI = 1.04, 6.01). We also observed elevated risk of child mortality (greater than median; adjusted HR = 1.92; 95% CI = 0.78, 4.68) in relation to prenatal arsenic exposure. Prospective studies should continue to evaluate prenatal and early life health effects of arsenic exposure and arsenic remediation strategies for women of child-bearing age.

The association of uterine leiomyoma and pregnancy is increasing due to the tendency of couples to delay first pregnancy after age 30. The risk of uterine fibroids is greater with advancing age of the woman. To evaluate the impact of fibroids on the incidence of complications during pregnancy, labor and delivery. We observed 65 pregnant patients with uterine fibroids and 165 pregnant patients without fibroids. Follow-up ultrasound was performed at weeks 20 to 24, 30 to 32 and 36 to 40. We analyzed the following variables: threatened abortion, pregnancy loss, preterm birth, premature rupture of membranes, abnormal fetal presentation, mode of termination of pregnancy, uterine atony, postpartum hemorrhage and perinatal outcome. The frequency of threatened abortion, risk of pregnancy loss in the second trimester, preterm births, premature rupture of membranes and abnormal fetal presentation was significantly higher in patients with uterine fibroids compared to patients without fibroids. It was not demonstrated that fibroids grow during follow-up even, there was a trend toward reduction in size as pregnancy progressed and until its completion. No significant differences in the frequency of cesarean section between groups (52.3 vs. 47.9%, RR 1.09; 95% CI 0.82-1.45, p = 0.646). Uterine atony was more frequent in patients with fibroids than in patients without fibroids (12.3 vs 4.2%, RR = 2.9, 95% CI 1.2-7.6, p = 0.036). There were no differences in perinatal outcomes between the groups. Uterine fibroids increase the risk of complications during pregnancy and childbirth. Could not be demonstrated an increased risk of caesarean section.

Sleep disorders in pregnancy

Sleep complaints are a common occurrence in pregnancy that are in part due to pregnancy-associated anatomic and physiological changes but may also be due to pathological causes. In the non-pregnant population, sleep deprivation has been associated with physical and cognitive issues; poor sleep may even be associated with adverse maternal outcomes. Maternal obesity, one of the most prevalent risk factors in obstetric practices, together with physiologic changes of pregnancy predispose to the development of sleep disordered breathing. Symptoms of sleep disordered breathing have also been associated with poor maternal outcomes. Management options of restless legs syndrome and narcolepsy pose a challenge in pregnancy; benefits of therapy need to be weighed against the potential harm to the fetus. This article briefly reviews the normal changes in pregnancy affecting sleep, gives an overview of certain sleep disorders occurring in pregnancy, and suggests management options specific for this population.

Pilot study to analyse the efficacy and embryo morphology using a new human embryo culture medium (GM501) versus the conventional used medium (ISM1). Over a four-month period, all patients at the Leuven Institute of Fertility and Embryology (LIFE) were -randomly allocated to have their embryos cultured in either the standard sequential culture medium ISM1 (control) or in a new universal medium (GM501) (study group). Primary outcome parameters were clinical pregnancy and live birth rate. The secondary outcome parameter was the correlation of embryo fragmentation rate with pregnancy outcome. We did not observe any differences between the ISM1 control group and GM501 study group with regard to fertilization, pregnancy, implantation rates, ongoing pregnancy, and babies born. The number of embryos with a minimal fragmentation rate (less than 30%) was significantly higher in the GM501 study group. Although a significant higher embryo fragmentation rate was seen in In vitro culture of embryos in GM501, pregnancy outcome results were comparable to those of embryos cultured in ISM1. According to our results the value of embryo morphological criteria as a parameter for pregnancy outcome should be examined and discussed again.

The effect of high ambient temperature (34 degrees C) on the function of the female reproductive system, on embryonic development and on outcome of pregnancy, was investigated in heat-exposed sham-operated (Sh) and pinealectomized (Px) golden hamsters maintained under short photoperiod. Plasma prolactin levels were reduced in both heat-exposed groups (ShH and PxH) but pituitary prolactin was increased in the pinealectomized groups irrespective of ambient temperature (21 or 34 degrees C). Pituitary weights and LH contents were not affected in any test group. Heat exposure brought about a reduction in the number of corpora lutea and of pups born, the latter being more drastically reduced in absence of the pineal; the depressant effect of heat on ovarian weight was evident only in the pinealectomized animals. Progesterone levels were not affected in any test group and pregnancy was not prolonged, thus, it would seem that pregnant hamsters adapt themselves well to heat. Moreover, high ambient temperature promoted a rise in pineal. HIOMT activity and boosted cortisol levels in presence of the pineal gland only, which, together with the above findings, shows that the pineal can provide protection for pregnant hamsters against adverse effects of high ambient temperature.

Objectives Mounting evidence from clinic and convenience samples suggests that stress is an important predictor of adverse obstetric outcomes. Using a proposed theoretical framework, this review identified and synthesized the population-based literature on the measurement of stress prior to and during pregnancy in relation to obstetric outcomes. Methods Population-based, peer-reviewed empirical articles that examined stress prior to or during pregnancy in relation to obstetric outcomes were identified in the PubMed and PsycInfo databases. Articles were evaluated to determine the domain(s) of stress (environmental, psychological, and/or biological), period(s) of stress (preconception and/or pregnancy), and strength of the association between stress and obstetric outcomes. Results Thirteen studies were evaluated. The identified studies were all conducted in developed countries. The majority of studies examined stress only during pregnancy (n=10); three examined stress during both the preconception and pregnancy periods (n=3). Most studies examined the environmental domain (e.g., life events) only (n=9), two studies examined the psychological domain only, and two studies examined both. No study incorporated a biological measure of stress. Environmental stressors before and during pregnancy were associated with worse obstetric outcomes, although some conflicting findings exist. Conclusions Few population-based studies have examined stress before or during pregnancy in relation to obstetric outcomes. Although considerable variation exists in the measurement of stress across studies, environmental stress increased the risk for poor obstetric outcomes. Additional work using a lifecourse approach is needed to fill the existing gaps in the literature and to develop a more comprehensive understanding of the mechanisms by which stress impacts obstetric outcomes.

To compare obstetric outcomes in women using illegal drugs with women who smoke cigarettes. Retrospective cohort study. Aberdeen, UK. All deliveries in Aberdeen in women using illegal drugs and women who smoked cigarettes during 1997-2007. The women who used illegal drugs were identified from a database of affected pregnant women in Aberdeen. The Aberdeen Maternity and Neonatal Databank was used to identify women who smoke cigarettes and to obtain pregnancy outcome information. Sociodemographic characteristics, maternal and perinatal outcomes were compared using chi-squared test, independent sample t-test and logistic regression analysis. Preterm delivery, low birthweight (standardized birthweight score <-2) and admission to the neonatal unit. Of the 561 illegal drug users, 96% were also cigarette smokers. Compared with women who smoke cigarettes with no reported illegal drug use, they were significantly more likely to have a preterm delivery [adjusted odds ratio (aOR) 1.6 (95% confidence interval (CI) 1.3-2.1)], low birthweight baby [aOR 1.9 (95%CI 1.4-2.6)], baby admitted to the neonatal unit [aOR 13.3 (95%CI 10.9-16.3)], deep vein thrombosis [aOR (95%CI 8.8-50.8)] and antepartum hemorrhage [aOR (95%CI 1.2-2.1)]. They were less likely to be at the extremes of age, or to develop pregnancy-induced hypertension [aOR 0.3 (95%CI 0.2-0.4)]. Illegal drug use in pregnancy appears to increase the risk of adverse outcomes, over and above that related to cigarette smoking, but appears to be associated with lower prevalence of gestational hypertension. © 2013 The Authors © 2013 Nordic Federation of Societies of Obstetrics and Gynecology.

Objective The objective of this study was to describe pregnancy outcomes, including cervical insufficiency and preterm birth, in the subsequent pregnancy following an intrapartum cervical laceration. Study Design Retrospective cohort of women with their first two consecutive singleton pregnancies carried to ≥ 200/7 weeks' gestation within a tertiary health care system from 2002 to 2012. Cervical laceration cases were identified by ICD9 codes and included if suture repair was required. Results In this study, 55 women were confirmed to have a cervical laceration in the first delivery; 43 lacerations after vaginal delivery (VD) and 12 after cesarean delivery (CD). The median gestational age of the first delivery was 400/7 weeks and the median birth weight 3,545 g; these did not differ between VD and CD. In the second pregnancy, 2 of 55 women (4.6%) had a prophylactic cerclage placed; 1 carried to term and the other delivered at 356/7 weeks. In total, four women (9.3%) delivered the second pregnancy < 37 weeks: three had a prior term VD and one had a prior 34 weeks VD. There was only one case of recurrent cervical laceration, occurring in the setting of vaginal deliveries. Conclusion Obstetric cervical lacerations are uncommon. Complications in the following pregnancy were low, despite lack of additional prophylactic cerclage use. PMID:27621953

Women taking antidepressant or anti-anxiety medications during early pregnancy have high risks of non-live pregnancy outcomes, although the contribution of the underlying illnesses to these risks remains unclear. We examined the impacts of antenatal depression and anxiety and of commonly prescribed treatments on the risks of non-live pregnancy outcomes. We identified all pregnancies and their outcome (live birth, perinatal death, miscarriage or termination) among women aged 15-45 years between 1990 and 2009 from a large primary care database in the United Kingdom. Women were grouped according to whether they had no history of depression and anxiety, a diagnosis of such illness prior to pregnancy, illness during pregnancy and illness during pregnancy with use of medication (stratified by medication type). Multinomial logistic regression models were used to compare risks of non-live outcomes among these groups, adjusting for major socio-demographic and lifestyle characteristics. Among 512,574 pregnancies in 331,414 women, those with antenatal drug exposure showed the greatest increased risks for all non-live pregnancy outcomes, relative to those with no history of depression or anxiety, although women with prior (but not currently medicated) illness also showed modest increased risks. Compared with un-medicated antenatal morbidity, there was weak evidence of an excess risk in women taking tricyclic antidepressants, and stronger evidence for other medications. Women with depression or anxiety have higher risks of miscarriage, perinatal death and decisions to terminate a pregnancy if prescribed psychotropic medication during early pregnancy than if not. Although underlying disease severity could also play a role, avoiding or reducing use of these drugs during early pregnancy may be advisable.

Reviews find a likely adverse effect of air pollution on perinatal outcomes, but variation of findings hinders the ability to incorporate the research into policy. The International Collaboration on Air Pollution and Pregnancy Outcomes (ICAPPO) was formed to better understand relationships between air pollution and adverse birth outcomes through standardized parallel analyses in datasets from different countries. A planning group with 10 members from 6 countries was formed to coordinate the project. Collaboration participants have datasets with air pollution values and birth outcomes. Eighteen research groups with data for approximately 20 locations in Asia, Australia, Europe, North America, and South America are participating, with most participating in an initial pilot study. Datasets generally cover the 1990s. Number of births is generally in the hundreds of thousands, but ranges from around 1,000 to about one million. Almost all participants have some measure of particulate matter, and most have ozone, nitrogen dioxide, sulfur dioxide and carbon monoxide. Strong enthusiasm for participating and a geographically-diverse range of participants should lead to understanding uncertainties about the role of air pollution in perinatal outcomes and provide decision-makers with better tools to account for pregnancy outcomes in air pollution policies.

Human immunodeficiency virus (HIV) infection is likely to have untoward effects on pregnancy and its outcome. This study assessed the impact of maternal HIV infection on pregnancy outcomes in a tertiary centre in Calabar, Nigeria. This retrospective study analysed delivery records of 258 HIV-positive and 257 HIV-negative women for pregnancy and delivery complications. Maternal and fetal outcomes of HIV-positive pregnancies were compared with those of HIV-negative controls. Adverse pregnancy outcomes significantly associated with HIV status were: anaemia: 33 (8.1%) vs. 8 (3.1%) in controls; puerperal sepsis: 18 (7%) vs. 2 (0.8%); and low birth weight: 56 (21.7%) vs. 37 (14.4%). Caesarean delivery was higher among HIV-positive women than controls: 96 (37.2%) vs. 58 (22.6%). Preterm births were higher in those HIV cohorts who did not receive antiretroviral therapy (ART): 13 (16.9%) vs. 7 (3.9%). HIV-positive status increased adverse birth outcome of pregnancy. ART appeared to reduce the risk of preterm births in HIV-positive cohorts. © The Author(s) 2015.

To examine the association between the information health professionals report providing parents about sex chromosome anomalies (SCAs) and the outcomes of affected pregnancies. Telephone interviews were conducted with health professionals who disclosed the prenatal diagnosis of an SCA to parents. The statements they reported providing to parents about the condition were coded as positive, neutral or negative. Outcomes of the pregnancies were obtained from medical records. Six of the 23 pregnancies were terminated. Health professionals reported giving parents of these six cases a greater amount of negative information about an SCA than did the health professionals reporting on the information given to the parents who continued with their pregnancies. Health professionals reported giving a similar amount of positive and neutral information to both groups of parents. The results of this pilot study suggest that there is a positive association between the amount of negative information parents are given initially about a sex chromosome anomaly and the decision to terminate the affected pregnancy. This study is limited by its small sample size and reliance on health professionals' self-reports of information provided to parents. Larger, prospective studies in which consultations are tape-recorded and linked to parents' subsequent decision making and adjustment are needed. Copyright 2003 John Wiley & Sons, Ltd.

Given the detrimental influence of maternal overweight and obesity on reproductive and pregnancy outcomes for the mother and child, it is the position of the American Dietetic Association and the American Society for Nutrition that all overweight and obese women of reproductive age should receive counseling on the roles of diet and physical activity in reproductive health prior to pregnancy,during pregnancy, and in the inter conceptional period, in order to ameliorate these adverse outcomes. The effect of maternal nutritional status prior to pregnancy on reproduction and pregnancy outcomes is of great public health importance. Obesity in the United States and worldwide has grown to epidemic proportions, with an estimated 33% of US women classified as obese. This position paper has two objectives: (a) to help nutrition professionals become aware of the risks and possible complications of overweight and obesity for fertility,the course of pregnancy, birth outcomes, and short- and long-term maternal and child health outcomes;and (b) related to the commitment to research by the American Dietetic Association and the American Society for Nutrition, to identify the gaps in research to improve our knowledge of the risks and complications associated with being overweight and obese before and during pregnancy.Only with an increased knowledge of these risks and complications can health care professionals develop effective strategies that can be implemented before and during pregnancy as well as during the inter conceptional period to ameliorate adverse outcomes.

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; P<0.001). There was no difference between the elective and emergency groups in mean pregnancy 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.

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

To compare pregnancy outcomes of two consecutive pregnancies in a cohort of women with recurrent pregnancy loss (RPL), in order to determine the long-term prognosis of women with RPL managed in a dedicated RPL clinic. A retrospective cohort study including 262 patients with two or more consecutive pregnancy losses followed by two subsequent pregnancies--index pregnancy (IP) and post-index pregnancy (PIP). All patients were evaluated and treated in the RPL clinic in the Soroka University Medical Center. Comparing IP with PIP, no significant difference in perinatal outcome was observed. The perinatal outcome remained encouraging with approximately 73% birth rate (73.7% versus 72.5%; p=0.83). Only 11% of the women with RPL continued to experience pregnancy losses for two subsequent pregnancies. In a multivariate logistic regression analysis, number of miscarriages pre-Index was the only factor independently associated with birth in the PIP. There is no significant difference between IP and PIP regarding perinatal outcome. Appropriate management in the RPL clinic conferred a significant beneficial effect on long-term pregnancy outcome of a cohort of women with RPL.

Recurrent pregnancy loss is a frequently occurring human infertility-related disease affecting ~1% of women. It has been estimated that the cause remains unexplained in >50% cases which strongly suggests that genetic factors may contribute towards the phenotype. Concerning its molecular aetiology numerous studies have had limited success in identifying the disease's genetic causes. This might have been due to the fact that hundreds of genes are involved in each physiological step necessary for guaranteeing reproductive success in mammals. In such scenario, next generation sequencing provides a potentially interesting tool for research into recurrent pregnancy loss causative mutations. The present study involved whole-exome sequencing and an innovative bioinformatics analysis, for the first time, in 49 unrelated women affected by recurrent pregnancy loss. We identified 27 coding variants (22 genes) potentially related to the phenotype (41% of patients). The affected genes, which were enriched by potentially deleterious sequence variants, belonged to distinct molecular cascades playing key roles in implantation/pregnancy biology. Using a quantum chemical approach method we established that mutations in MMP-10 and FGA proteins led to substantial energetic modifications suggesting an impact on their functions and/or stability. The next generation sequencing and bioinformatics approaches presented here represent an efficient way to find mutations, having potentially moderate/strong functional effects, associated with recurrent pregnancy loss aetiology. We consider that some of these variants (and genes) represent probable future biomarkers for recurrent pregnancy loss.

Aim of the study: Pilot study to analyse the efficacy and embryo morphology using a new human embryo culture medium (GM501) versus the conventional used medium (ISM1). Methods: Over a four-month period, all patients at the Leuven Institute of Fertility and Embryology (LIFE) were randomly allocated to have their embryos cultured in either the standard sequential culture medium ISM1 (control) or in a new universal medium (GM501) (study group). Primary outcome parameters were clinical pregnancy and live birth rate. The secondary outcome parameter was the correlation of embryo fragmentation rate with pregnancy outcome. Results: We did not observe any differences between the ISM1 control group and GM501 study group with regard to fertilization, pregnancy, implantation rates, ongoing pregnancy, and babies born. The number of embryos with a minimal fragmentation rate (less than 30%) was significantly higher in the GM501 study group. Conclusion: Although a significant higher embryo fragmentation rate was seen in In vitro culture of embryos in GM501, pregnancy outcome results were comparable to those of embryos cultured in ISM1. According to our results the value of embryo morphological criteria as a parameter for pregnancy outcome should be examined and discussed again. PMID:25009716

To evaluate whether the freeze-all strategy affects in vitro fertilization (IVF) outcomes in poor ovarian responders following the Bologna criteria. We performed a retrospective cohort study conducted between January 2012 and December 2016. A total of 433 poor responders (per the Bologna criteria) fulfilled the inclusion/exclusion criteria and were included in the study, with 277 patients included in the fresh group and 156 in the freeze-all group. All patients were submitted to controlled ovarian stimulation (COS) with a gonadotropin-releasing hormone antagonist protocol and cleavage-stage embryo transfer (ET). The main outcome measure was ongoing pregnancy rate. Secondary outcomes included implantation and clinical pregnancy rates. The freeze-all strategy was implemented when the progesterone serum level was >1.5 ng/mL on the trigger day, when the endometrium was <7 mm on the trigger day, or as a patient preference. Patients with previous failed fresh embryo transfer were also submitted to fresh or freeze-all strategy considering the indications mentioned above. The patients' mean age in the freeze-all group was 39.5±3.6 years, while that of patients in the fresh group was 39.7±3.8 years (P=0.54). The mean number of embryos transferred (nET) was 1.53±0.6 and 1.60±0.6 (P=0.12) in the freeze-all and fresh groups, respectively. Ongoing pregnancy rates did not significantly differ between the freeze-all and fresh groups (9.6% versus 10.1%, respectively; Relative Risk [RR]: 0.95; 95% CI: 0.52-1.73), nor did the clinical pregnancy rates (14.1% versus 13.7%, respectively; RR: 1.03; 95% CI: 0.63-1.76). Implantation rates were 9.6% and 9.8% (P=0.82) in the freeze-all and fresh groups, respectively. The logistic regression analysis (including age, antral follicle count [AFC], the number of retrieved oocytes, the number of mature oocytes, nET, and fresh versus freeze-all strategy) indicated that age (P<0.001) and the nET (P=0.039) were the only independent variables

Borderline ovarian tumors (BOTs) represent a type of epithelial tumors having a biologic intermediate behavior between clearly malignant and straight benign tumors. Most of BOTs interest women during fertile age, for which it is necessary to consider a fertility sparing surgery. To evaluate the clinical aspects and pregnancy rate of women affected by borderline ovarian tumors who have undergone fertility sparing surgery. A study of 22 patients affected by BOTs who have been treated with a fertility sparing surgery was conducted between January 2005 and October 2011 at Sant'Andrea Hospital, "Sapienza" University of Rome. The patients' characteristics analyzed were: age, histological type, tumor size, adnexal surgery, pre-operative serum CA-125, diagnostic circumstances, number of patients who became pregnant and number of overall pregnancies. Among the 22 patients treated with a fertility sparing surgery, only sixteen wanted to get pregnant. Eleven patents out of 16 accomplished it. The pregnancy rate was 68.7%. Fertility sparing surgery can be considered a safe procedure for young women affected by borderline ovarian tumors.

To determine how psychosocial factors affect the association between a history of abuse and postpartum depression (PPD). Women at four urban hospitals in Utah were enrolled ≤ 48 h of delivering a live-born infant. At enrollment, pregravid history of physical or sexual abuse was obtained via self-report. Psychosocial covariates such as pregnancy stressors and depression were also collected. Pregnancy stressors were categorized using "stressor" questions from the Pregnancy Risk Assessment Monitoring System. The primary outcome measure, a pre-specified Edinburgh Postnatal Depression Scale score of ≥ 12 was obtained 6-8 weeks postpartum. Among the 1,038 women studied, psychosocial risk factors were common: abuse history 11.7%, pregnancy stressors-financial 49.1%, emotional 35.0%, partner-associated 19.8%, and traumatic 10.3% and depression history 16.7%. While abuse was associated with a +PPD screen in a preliminary model [aOR 2.05 (1.28, 3.26)], adding psychosocial covariates reduced the unadjusted association of abuse and PPD [aOR 1.12 (0.66, 1.91)]. After adjustment, PPD was associated with depression history [aOR 2.85 (1.90, 4.28)], prepregnancy BMI [aOR 1.04 (1.01, 1.07)] multiple stressors [3 categories aOR 4.35 (2.00, 9.46)]; 4 categories [aOR 6.36 (2.07, 19.49)] and sum of stressors * history of abuse [aOR 1.50 (0.92, 2.46)]. Interestingly only women with a moderate number of stressors were sensitive to an abuse history. Abuse and pregnancy stressors are common and interact to influence the likelihood of screening positive for PPD.

Patent foramen ovale (PFO)-related stroke is increasingly recognized as an important etiology of ischemic embolic stroke-accounting for up to 50% of strokes previously considered 'cryptogenic' or with an unknown mechanism. As a 'back door to the brain,' PFO can allow venous clots to enter arterial circulation via interatrial right-to-left shunting, potentially resulting in ischemic stroke. We observe that clinically, PFO-related stroke affects women of childbearing age, and that pregnancy-owing to major changes in hemocoagulative, hormonal, and cardiovascular parameters-can enhance stroke risks. However, no systematic study has been performed and little is known regarding complications, pregnancy outcomes and treatment for PFO-related stroke during pregnancy. To identify and characterize the complications and clinical outcomes related to PFOs during pregnancy, we performed a literature review and analysis from all reported cases of pregnancy with PFO-related complications in the medical literature from 1970 to 2015. We find that during pregnancy and post-partum, PFO is associated with complications affecting multiple organs, including the brain, heart and lung. The three principal complications reported are stroke, pulmonary emboli and myocardial infarction. In contrast to other pregnancy-related stroke etiologies, which peak during later pregnancy and postpartum, PFO-related stroke peaks during early pregnancy (first and second trimester-60%), and most patients had good neurological outcome (77%). In patients with PFO with recurrent stroke during pregnancy, additional key factors include high-risk PFO morphology (atrial septal aneurysm), larger right-to-left shunt, multiple gestation and concurrent hypercoagulability. Compared to strokes of other etiologies during pregnancy, most PFO stroke patients experienced uneventful delivery (93%) of healthy babies with a good clinical outcome. We conclude with recommended clinical treatment strategies for pregnant patients

The vaginal microflora of a healthy asymptomatic woman consists of a wide variety of anaerobic and aerobic bacterial genera and species dominated by the facultative, microaerophilic, anaerobic genus Lactobacillus. The activity of Lactobacillus is essential to protect women from genital infections and to maintain the natural healthy balance of the vaginal flora. Increasing evidence associates abnormalities in vaginal flora during pregnancy with preterm labor and delivery with potential neonatal sequelae due to prematurity and poor perinatal outcome. Although this phenomenon is relatively common, even in populations of women at low risk for adverse events, the pathogenetic mechanism that leads to complications in pregnancy is still poorly understood. This review summarizes the current knowledge and uncertainties in defining alterations of vaginal flora in non-pregnant adult women and during pregnancy, and, in particular, investigates the issue of bacterial vaginosis and aerobic vaginitis. This could help specialists to identify women amenable to treatment during pregnancy leading to the possibility to reduce the preterm birth rate, preterm premature rupture of membranes, chorioamnionitis, neonatal, puerperal and maternal-fetal infectious diseases. Vaginal ecosystem study with the detection of pathogens is a key instrument in the prevention of preterm delivery, pPROM, chorioamnionitis, neonatal, puerperal and maternal-fetal infections.

Identification of risk factors for adverse obstetrical outcomes after appendectomy and cholecystectomy during pregnancy is necessary for evidence-based risk reduction and adequate patient counseling. To identify risk factors for adverse obstetrical outcomes after appendectomy and cholecystectomy during pregnancy and stratify the risk of such outcomes. A cohort study was conducted using the Nationwide Inpatient Sample, a nationally representative sample of patients discharged from community hospitals in the United States, from January 1, 2003, to December 31, 2012. Multivariable analysis of risk factors for adverse obstetric outcomes was performed for 19 926 women undergoing appendectomy or cholecystectomy during pregnancy and a scoring system for such risk factors was developed. Data analysis was conducted from January 1, 2015, to July 31, 2016. A composite measure including 7 adverse obstetrical outcomes throughout pregnancy and occurring before hospital discharge. Of the 19 926 women (mean [SD] age, 26 [6] years) in the study, 1018 adverse obstetrical events were recorded in 953 pregnant women (4.8%). The 3 most frequent adverse events were preterm delivery (360 [35.4%]), preterm labor without preterm delivery (269 [26.4%]), and miscarriage (262 [25.7%]). The risk factors associated most strongly with an adverse obstetrical outcome included cervical incompetence (adjusted odds ratio, 24.29; 95% CI, 7.48-78.81), preterm labor during current pregnancy (adjusted odds ratio, 18.34; 95% CI, 4.95-67.96), vaginitis or vulvovaginitis (adjusted odds ratio, 5.17; 95% CI, 2.19-12.23), and sepsis (adjusted odds ratio, 3.39; 95% CI, 2.08-5.51). A scoring system based on statistically significant variables classified the study sample into 3 risk groups corresponding to predicted probabilities of adverse obstetrical outcomes of 2.5% (≤4 points), 8.2% (5-8 points), and 21.8% (≥9 points). Approximately 5% of women experience adverse obstetrical outcomes after appendectomy

To assess the outcomes and risk factors of adolescent pregnancies in 2 major hospitals in Malaysia. We conducted a case-control study of pregnant girls aged 10 through 19 years. The controls were women aged 20 through 35 years who did not become pregnant in their adolescence. Cases and controls were matched for parity and place of delivery. Data were collected from questionnaires and the hospitals' medical records. The study included 102 cases and 102 controls. There were significant associations between adolescent pregnancy and low education level, low socioeconomic status, being raised by a single parent, not engaging in extracurricular school activities, engaging in unsupervised activities with peers after school, and substance abuse (P<0.05 for all); being anemic, being unsure of the expected delivery date, and having few antenatal visits and a late delivery booking; and low Apgar scores and perinatal complications. Adolescent pregnancies are high-risk pregnancies. Better sexual health strategies are required to address the associated complications.

Pregnancy associated cardiovascular pathologies have a significant impact on outcome for mother and child. Bioimpedance cardiography may provide additional outcome-relevant information early in pregnancy and may also be used as a predictive instrument for pregnancy-associated diseases. We performed a prospective longitudinal cohort trial in an outpatient setting and included 242 pregnant women. Cardiac output and concomitant hemodynamic data were recorded from 11(th)-13(th) week of gestation every 5(th) week as well as at two occasions post partum employing bioimpedance cardiography. Cardiac output increased during pregnancy and peaked early in the third trimester. A higher heart rate and a decreased systemic vascular resistance were accountable for the observed changes. Women who had a pregnancy-associated disease during a previous pregnancy or developed hypertension or preeclampsia had a significantly increased cardiac output early in pregnancy. Furthermore, an effect of cardiac output on birthweight was found in healthy pregnancies and could be confirmed with multiple linear regression analysis. Cardiovascular adaptation during pregnancy is characterized by distinct pattern described herein. These may be altered in women at risk for preeclampsia or reduced birthweigth. The assessment of cardiac parameters by bioimpedance cardiography could be performed at low costs without additional risks.

Epidemiological studies have found that maternal exposure to disinfection by-products (DBPs) may lead to adverse pregnancy outcomes although the findings tend to be inconsistent. The objective of this study was to systematically review the evidence in associated with drinking water DBP exposure in relation to adverse pregnancy outcomes. Peer-reviewed articles were identified using electronic databases searched for studies published in the English language. Studies selected for review were evaluated for exposure assessment, confounders, and analyses risks of bias in the selection, outcomes assessment, and attrition. A comprehensive search and screening yielded a total of 32 studies, of which 12 (38%) reported a statistical association between maternal exposure to DBPs and adverse pregnancy outcomes. A maternal exposure to trihalomethanes (THMs) shows an increased risk of small for gestational age (SGA) and slightly increased risk of pregnancy loss. Risks of bias were low among the studies included in the review. Evidence on association relating to adverse pregnancy outcomes to DBP exposure is still less significant. There is a need for future robust research in this field, with the use of urinary trichloroacetic acid (TCAA) biomarkers as a direct exposure assessment method for this field.

Lack of trace elements during pregnancy is detrimental to maternal and fetal health. Our aim is to study the changes in trace element levels in Chinese pregnant women and their association with adverse pregnancy outcomes. 1568 cases of Chinese pregnant women in remote areas were collected for a prospective cohort study. Serum copper, zinc, calcium and iron levels were measured at pre-pregnancy, 1st trimester (7w-12w), 2nd trimester (24w-28w) and 3rd trimester (35w-40w). (1) Serum copper levels was significantly higher after pregnancy than before, calcium and iron levels decreased, but zinc levels did not change significantly. (2) Copper and zinc deficiency in pregnant women was not a common finding, but lack of iron and calcium was frequently encountered; iron deficiency was especially common in the 3rd trimester (42.27%). (3) Serum zinc and iron levels in patients who either had a miscarriage or a preterm delivery were significantly lower than in the control group (p < 0.05). In patients with premature rupture of membranes, serum zinc levels were significantly lower (p < 0.05). In patients with intrauterine growth restriction (IUGR), serum copper, zinc, calcium and iron were significantly lower (p < 0.05). Trace elements is closely associated with fetal growth and development during pregnancy. Deficiency can lead to adverse pregnancy outcomes. Therefore, we should have a reasonable diet, replenish trace elements, therefore reducing the occurrence of adverse pregnancy outcomes.

Children, at least 2 years of age, underwent an assessment of neurologic, motor and cognitive development using standardised psychometric tests and the parents completed a behavioural questionnaire. A composite outcome termed neurodevelopmental impairment including cerebral palsy (GMFCS II-V), cognitive and/or motor test score of <70, bilateral blindness or bilateral deafness requiring amplification. A total of 131 monochorionic pregnancies were treated with selective feticide at the Leiden University Medical Centre. Overall survival rate was 88/131 (67%). Long-term outcome was assessed in 74/88 (84%). Neurodevelopmental impairment was detected in 5/74 [6.8%, 95% confidence interval (CI), 1.1-12.5] of survivors. Overall adverse outcome, including perinatal mortality or neurodevelopmental impairment was 48/131 (36.6%). In multivariate analysis, parental educational level was associated with cognitive test scores (regression coefficient B 3.9, 95% CI 1.8-6.0). Behavioural problems were reported in 10/69 (14.5%). Adverse long-term outcome in survivor twins of complicated monochorionic pregnancies treated with selective feticide appears to be more prevalent than in the general population. Cognitive test scores were associated with parental educational level. Neurodevelopmental impairment after selective feticide was detected in 5/74 (6.8%, 95% CI 1.1-12.5) of survivors. © 2015 Royal College of Obstetricians and Gynaecologists.

Women who have experienced childhood trauma may be at risk for postpartum depression, increasing the likelihood of negative outcomes among their children. Predictive pathways from maternal childhood trauma to child outcomes, as mediated by postpartum depression, require investigation. A longitudinal sample of South African women (N=150) was followed through pregnancy and postpartum. Measures included maternal trauma history reported during pregnancy; postpartum depression through six months; and maternal-infant bonding, infant development, and infant physical growth at one year. Structural equation models tested postpartum depression as a mediator between maternal experiences of childhood trauma and children's outcomes. A subset of women (N=33) also participated in a lab-based emotional Stroop paradigm, and their responses to fearful stimuli at six weeks were explored as a potential mechanism linking maternal childhood trauma, postpartum depression, and child outcomes. Women with childhood trauma experienced greater depressive symptoms through six months postpartum, which then predicted negative child outcomes at one year. Mediating effects of postpartum depression were significant, and persisted for maternal-infant bonding and infant growth after controlling for covariates and antenatal distress. Maternal avoidance of fearful stimuli emerged as a potential affective mechanism. Limitations included modest sample size, self-report measures, and unmeasured potential confounders. Findings suggest a mediating role of postpartum depression in the intergenerational transmission of negative outcomes. Perinatal interventions that address maternal trauma histories and depression, as well as underlying affective mechanisms, may help interrupt cycles of disadvantage, particularly in high-trauma settings such as South Africa.

Methotrexate (MTX) is a known teratogenic drug used off-label in the treatment of ectopic pregnancies (EP). As MTX polyglutamated derivatives remains into the cells during several weeks, it is recommended to avoid conception during 3 to 6 months following MTX therapy. We report the follow-up of pregnancies after preconceptional exposure to MTX for EP. Prospective cases of pregnancy occurring within 3 months after MTX injection for an EP recorded in the Terappel database were analyzed. Data were obtained on 52 pregnant women. The median age of patients was 28 (18-38), and the median gestational age at inclusion was 7 weeks after last menstrual period (3-22). The time between the last MTX injection and conception ranged from 12 days to 13 weeks and the total MTX dose was between 40 to 210mg. Out of 45 pregnancies with known outcome, there were 39 live births (87%), 3 spontaneous abortions (6.7%) occurring 63 to 94 days after MTX administration, 2 elective terminations, and 1 medical termination after premature rupture of membranes, oligohydramnios and arthrogryposis (48mg of MTX 9 and 8 weeks before conception). Two additional cases of major malformations were observed among 40 examinable babies or fetuses: tetralogy of Fallot (MTX 6 weeks before conception), and cerebral ventriculomegaly with normal karyotype (50mg of MTX 9 to 13 weeks before conception). The resulting rate of major malformations was 7.5% (95% CI: 1.6-20.4). Although this prospective study shows a major malformation rate higher than expected in the general population, the observed malformations are not consistent with the typical pattern of methotrexate embryopathy. However, the case of tetralogy of Fallot is reminiscent of previously published cases with MTX exposure during early pregnancy. Owing to the small sample size, more powerful studies are needed to confirm or refute these findings. Copyright © 2016 Société française de pharmacologie et de thérapeutique. Published by Elsevier

Periodontitis in Pregnant Baboons: Systemic Inflammation and Adaptive Immune Responses and Pregnancy Outcomes in a Baboon Model

Chronic periodontal infections have been suggested to contribute to the risk of adverse pregnancy outcomes. This study describes the relationship of patterns of systemic inflammatory mediators and IgG antibody to 20 oral bacteria in pregnant female baboons (Papio anubis) coupled with clinical features of ligature-induced periodontitis, as risk indicators for adverse pregnancy outcomes. Animals showing a preterm delivery and/or low birth weight newborns, as well as those pregnancies resulting in spontaneous abortion, stillbirth, or fetal demise were tabulated as adverse pregnancy outcomes. A significantly greater frequency of the periodontitis group neonates had a low birth weight (18.1%; p=0.008) and decreased gestational age (9.8%). Spontaneous abortion/stillbirth/fetal demise were increased in the periodontitis (8.7%) versus the control group (3.8%) (p=0.054). The baseline oral clinical presentation of the experimental animals did not relate to the adverse pregnancy outcomes. Animals with the greatest extent/severity of periodontitis progression during the initial ½ of gestation (ie. to mid-pregnancy) had the greatest risk for adverse pregnancy outcomes. Baseline biological parameters indicating historical responses of the animals to periodontal challenge demonstrated individual variation in selected mediators, some of which became more differential during ligature-induced periodontitis. The relationship of clinical parameters to systemic inflammatory responses was consistent with a temporal contribution to adverse pregnancy outcomes in a subset of the animals. These results support a link between periodontitis and adverse pregnancy outcomes in the baboons and provide a prospective experimental model for delineating the biologic parameters that contribute to a causal relationship between chronic oral infections and birth events.

Teriflunomide, indicated for the treatment of relapsing-remitting multiple sclerosis, is contraindicated in pregnancy based on signs of developmental toxicity in the offspring of rats and rabbits; developmental toxicity has also been observed in preclinical studies of other disease-modifying therapies. Despite the requirement to use reliable contraception in clinical trials evaluating the safety and efficacy of teriflunomide, a number of pregnancies have been reported. This work reports pregnancy outcomes in teriflunomide clinical trials. Pregnancy outcomes were evaluated in a retrospective analysis of the global pharmacovigilance database. The following information was collected from the pharmacovigilance database or individual patient files: treatment allocation, pregnancy outcome, teriflunomide exposure, and use of the accelerated elimination procedure. At data cut-off, 83 pregnancies were reported in female patients and 22 pregnancies were documented in partners of male patients. All newborns were healthy and did not have any structural or functional abnormalities at birth. Available data do not indicate any teratogenic signals in patients treated with teriflunomide.

OBJECTIVES--To study the age of the start of the fall (critical age) in fecundity; the probability of a pregnancy leading to a healthy baby taking into account the age of the woman; and, combining these results, to determine the age dependent probability of getting a healthy baby. DESIGN--Cohort study of all women who had entered a donor insemination programme. SETTING--Two fertility clinics serving a large part of The Netherlands. SUBJECTS--Of 1637 women attending for artificial insemination 751 fulfilled the selection criteria, being married to an azoospermic husband and nulliparous and never having received donor insemination before. MAIN OUTCOME MEASURES--The number of cycles before pregnancy (a positive pregnancy test result) or stopping treatment; and result of the pregnancy (successful outcome). RESULTS--Of the 751 women, 555 became pregnant and 461 had healthy babies. The fall in fecundity was estimated to start at around 31 years (critical age); after 12 cycles the probability of pregnancy in a woman aged greater than 31 was 0.54 compared with 0.74 in a woman aged 20.31. After 24 cycles this difference had decreased (probability of conception 0.75 in women greater than 31 and 0.85 in women 20.31). The probability of having a healthy baby also decreased--by 3.5% a year after the age of 30. Combining both these age effects, the chance of a woman aged 35 having a healthy baby was about half that of a woman aged 25. CONCLUSION--After the age of 31 the probability of conception falls rapidly, but this can be partly compensated for by continuing insemination for more cycles. In addition, the probability of an adverse pregnancy outcome starts to increase at about the same age. PMID:2059713

Background We assessed the association between perfluorooctanoic acid (PFOA) and pregnancy outcome in an area with elevated exposure to PFOA from drinking water contaminated by chemical plant releases. Methods Serum PFOA was measured and reproductive and residential histories were obtained in 2005 – 2006. We estimated serum PFOA levels at the time of pregnancy for 11,737 pregnancies occurring between 1990 and 2006 based on historical information on PFOA releases, environmental distribution, pharmacokinetic modeling, and residential histories. We assessed the association between PFOA and the odds of miscarriage, stillbirth, preeclampsia, preterm birth, term low birthweight, and birth defects controlling for calendar time, age, parity, education, and smoking. PFOA exposure was evaluated as a continuous measure (with and without log-transformation) and in quintiles, combining the lowest two quintiles (<6.8 ng/mL) as the referent. Results Measures of association between PFOA and miscarriage, preterm birth, term low birthweight, and birth defects were close to the null. Odds of stillbirth were elevated in the 4th quintile only. For preeclampsia, the odds ratio was 1.13 (95% confidence interval = 1.00 – 1.28) for an interquartile shift in log-transformed PFOA, and the odds ratios were 1.1 – 1.2 across the upper three quintiles of exposure. Conclusions In this large, population-based study in a region with markedly elevated PFOA exposure, we found no associations between estimated serum PFOA levels and adverse pregnancy outcomes other than possibly preeclampsia. Conclusions are tempered by inherent limitations in exposure reconstruction and self-reported pregnancy outcome information. PMID:22370857

To determine the etiology and outcome of Acute Renal Failure (ARF) in pregnancy. A case series. Nephrology Department of the Jinnah Postgraduate Medical Centre, Karachi, from August 2007 to July 2008. Pregnant women who were healthy previously and had developed ARF, diagnosed on oliguria (urine output <400 ml/day) and mounting azotemia (serum creatinine > 2 mg%) were included in the study. Percutaneous renal biopsy was performed for delayed recovery, i.e. after three weeks. Patients were followed up for a period of 6 months. Percentages were calculated for qualitative variables i.e. causes of ARF, mortality, morbidity and outcome in form of complete recovery, partial recovery, demise and non-recovery. A total of 43 patients with pregnancy-related ARF were included in the study. The puerperal group comprised 36 patients (83.7%). Haemorrhage was the etiology for ARF in 25 (58.1%), antepartum haemorrhage APH in 8 (18.6%) and postpartum haemorrhage PPH in 16 (37.2%) of patients. In 12 (27.9%), puerperal sepsis was the etiological factor, while 4 (9.3%) patients had DIC on presentation. Pre-eclampsia, eclampsia and HELLP syndrome accounted for 5 (11.6%). While 1 (2.3%) was diagnosed with hemolytic uremic syndrome and another one was diagnosed as ARF secondary to hypotension produced by hyperemesis gravidarum. Renal biopsy was performed in 31 patients showing that 10 had acute cortical necrosis and 21 had acute tubular necrosis. Maternal mortality was 16.2% (n=7). Of the 36 (83.7%) surviving patients, 18 (41.4%) had complete recovery of renal function; 12 (27.9%) had partial recovery; and 6 (13.9%) required chronic dialysis. Pregnancy-related ARF was associated with poor outcome. Antepartum and postpartum haemorrhage were the most common cause of ARF in pregnancy.

Study Objectives: To examine the association between sleep apnea and pregnancy outcomes in a large population-based cohort. Methods: Population-based cohort study using linked birth and hospital records was conducted in New South Wales, Australia. Participants were all women who gave birth from 2002 to 2012 (n = 636,227). Sleep apnea in the year before pregnancy or during pregnancy was identified from hospital records. Outcomes of interest were gestational diabetes, pregnancy hypertension, planned delivery, caesarean section, preterm birth, perinatal death, 5-minute Apgar score, admission to neonatal intensive care or special care nursery, and infant size for gestational age. Maternal outcomes were identified using a combination of hospital and birth records. Infant outcomes came from the birth record. Modified Poisson regression models were used to examine associations between sleep apnea and each outcome taking into account maternal age, country of birth, socioeconomic disadvantage, smoking, obesity, parity, pre-existing diabetes and hypertension. Results: Sleep apnea was significantly associated with pregnancy hypertension (adjusted RR 1.43; 95% CI 1.18–1.73), planned delivery (1.15; 1.07–1.23), preterm birth (1.50; 1.21–1.84), 5-minute Apgar < 7 (1.60; 1.07–2.38), admission to neonatal intensive care/special care nursery (1.26; 1.11–1.44), large-for-gestational-age infants (1.27; 1.04–1.55) but not with gestational diabetes (1.09; 0.82–1.46), caesarean section (1.06; 0.96–1.17), perinatal death (1.73; 0.92–3.25), or small-for-gestational-age infants (0.81; 0.61–1.08). Conclusions: Sleep apnea is associated with higher rates of obstetric complications and intervention, as well as preterm delivery. Future research should examine if these are independent of obstetric history. Citation: Bin YS, Cistulli PA, Ford JB.

Information on gestational surrogacy arrangement and outcomes is limited in Australia. This national population study investigates the epidemiology of gestational surrogacy arrangement in Australia: treatment procedures, pregnancy and birth outcomes. A retrospective study was conducted of 169 intended parents cycles and 388 gestational carrier cycles in Australia in 2004-2011. Demographics were compared between intended parents and gestational carrier cycles. Pregnancy and birth outcomes were compared by number of embryos transferred. Over half (54%) intended parents cycles were in women aged <35 years compared to 38% of gestational carrier cycles. About 77% of intended parents cycles were of nulliparous women compared to 29% of gestational carrier cycles. Of the 360 embryo transfer cycles, 91% had cryopreserved embryos transferred and 69% were single-embryo transfer (SET) cycles. The rates of clinical pregnancy and live delivery were 26% and 19%, respectively. There were no differences in rates of clinical pregnancy and live delivery between SET cycles (27% and 19%) and double-embryo transfer (DET) cycles (25% and 19%). Five of 22 deliveries following DET were twin deliveries compared to none of 48 deliveries following SET. There were 73 liveborn babies following gestational surrogacy treatment, including 9 liveborn twins. Of these, 22% (16) were preterm and 14% (10) were low birthweight. Preterm birth was 13% for liveborn babies following SET, lower than the 31% or liveborn babies following DET. To avoid adverse outcomes for both carriers and babies, SET should be advocated in all gestational surrogacy arrangements. © 2016 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

Maternal psychological distress during pregnancy is a potential risk factor for various birth complications. This study aimed to explore psychological factors associated with adverse birth outcomes. Symptoms of psychological distress, individual characteristics, and medical complications were assessed at two time points antenatally in 285 women from Australia and New Zealand; birth outcomes were assessed postpartum, between January 2014 and September 2015. Hierarchical multiple regression analyses were conducted to examine the relation of psychological distress to adverse birth outcomes. Medical complications during pregnancy, such as serious infections, placental problems and preeclampsia, and antenatal cannabis use, were the factors most strongly associated with adverse birth outcomes, accounting for 22 percent of the total variance (p < .001). Symptoms of depression and/or anxiety, low social support, and low sense of coherence were not associated with birth complications. In unadjusted analyses, self-reported diagnosis of anxiety disorder during pregnancy and an orientation toward a Regulator mothering style were associated with adverse birth outcomes; however, after controlling for medical complications, these were no longer associated. Our study results indicate that antenatal depressive and/or anxiety symptoms were not independently associated with adverse birth outcomes, a reassuring finding for women who are already psychologically vulnerable during pregnancy.

To characterise the obstetrical management and outcomes in a series of women with a history of Kawasaki disease (KD) in childhood. Retrospective case series. Tertiary healthcare setting in the USA. Women with a history of KD in childhood. Women completed a detailed health questionnaire and participated in research imaging studies as part of the San Diego Adult KD Collaborative Study. Obstetrical management, complications during pregnancy and delivery, and infant outcomes. Ten women with a history of KD in childhood carried a total of 21 pregnancies to term. There were no cardiovascular complications during labour and delivery despite important cardiovascular abnormalities in four of the ten subjects. Pregnancy was complicated by pre-eclampsia and the post-partum course was complicated by haemorrhage in one subject each. Two of the 21 progeny subsequently developed KD. Women with important cardiovascular sequelae from KD in childhood should be managed by a team that includes both a maternal-fetal medicine specialist and a cardiologist. Pre-pregnancy counselling should include delineation of the woman's current functional and structural cardiovascular status and appropriate adjustment of medications, but excellent outcomes are possible with appropriate care. Review of the English and Japanese literature on KD and pregnancy revealed the occurrence of myocardial infarction during pregnancy in women with missed KD and aneurysms that were not diagnosed until their acute event. Our study highlights the need for counselling with regard to the increased genetic risk of KD in offspring born to these mothers. © 2014 Royal College of Obstetricians and Gynaecologists.

Importance Identification of risk factors for adverse obstetrical outcomes after appendectomy and cholecystectomy during pregnancy is necessary for evidence-based risk reduction and adequate patient counseling. Objectives To identify risk factors for adverse obstetrical outcomes after appendectomy and cholecystectomy during pregnancy and stratify the risk of such outcomes. Design, Setting, and Participants A cohort study was conducted using the Nationwide Inpatient Sample, a nationally representative sample of patients discharged from community hospitals in the United States, from January 1, 2003, to December 31, 2012. Multivariable analysis of risk factors for adverse obstetric outcomes was performed for 19 926 women undergoing appendectomy or cholecystectomy during pregnancy and a scoring system for such risk factors was developed. Data analysis was conducted from January 1, 2015, to July 31, 2016. Main Outcomes and Measures A composite measure including 7 adverse obstetrical outcomes throughout pregnancy and occurring before hospital discharge. Results Of the 19 926 women (mean [SD] age, 26 [6] years) in the study, 1018 adverse obstetrical events were recorded in 953 pregnant women (4.8%). The 3 most frequent adverse events were preterm delivery (360 [35.4%]), preterm labor without preterm delivery (269 [26.4%]), and miscarriage (262 [25.7%]). The risk factors associated most strongly with an adverse obstetrical outcome included cervical incompetence (adjusted odds ratio, 24.29; 95% CI, 7.48-78.81), preterm labor during current pregnancy (adjusted odds ratio, 18.34; 95% CI, 4.95-67.96), vaginitis or vulvovaginitis (adjusted odds ratio, 5.17; 95% CI, 2.19-12.23), and sepsis (adjusted odds ratio, 3.39; 95% CI, 2.08-5.51). A scoring system based on statistically significant variables classified the study sample into 3 risk groups corresponding to predicted probabilities of adverse obstetrical outcomes of 2.5% (≤4 points), 8.2% (5-8 points), and 21.8% (≥9

2015-01-01

Background Anaemia in pregnancy is a major public health and economic problem worldwide, that contributes to both maternal and fetal morbidity and mortality. Objective The aim of the study was to calculate the prevalence of anaemia in early pregnancy in a cohort of ‘low risk’ women participating in a large international multicentre prospective study (n = 5 609), to identify the modifiable risk factors for anaemia in pregnancy in this cohort, and to compare the birth outcomes between pregnancies with and without anaemia in early gestation. Methods The study is an analysis of data that were collected prospectively during the Screening for Pregnancy Endpoints study. Anaemia was defined according to the World Health Organization’s definition of anaemia in pregnancy (haemoglobin < 11g/dL). Binary logistic regression with adjustment for potential confounders (country, maternal age, having a marital partner, ethnic origin, years of schooling, and having paid work) was the main method of analysis. Results The hallmark findings were the low prevalence of anaemia (2.2%), that having no marital partner was an independent risk factor for having anaemia (OR 1.34, 95% CI 1.01-1.78), and that there was no statistically significant effect of anaemia on adverse pregnancy outcomes (small for gestational age, pre-tem birth, mode of delivery, low birth weight, APGAR score < 7 at one and five minutes). Adverse pregnancy outcomes were however more common in those with anaemia than in those without. Conclusion In this low risk healthy pregnant population we found a low anaemia rate. The absence of a marital partner was a non-modifiable factor, albeit one which may reflect a variety of confounding factors, that should be considered for addition to anaemia’s conceptual framework of determinants. Although not statistically significant, clinically, a trend towards a higher risk of adverse pregnancy outcomes was observed in women that were anaemic in early pregnancy. PMID:25875012

Diet around conception and during pregnancy--effects on fetal and neonatal outcomes.

PubMed

Kind, Karen L; Moore, Vivienne M; Davies, Michael J

2006-05-01

Substrate supply to the fetus is a major regulator of prenatal growth. Maternal nutrition influences the availability of nutrients for transfer to the fetus. Animal experiments demonstrate that restriction of maternal protein or energy intake can retard fetal growth. Effects of maternal nutrition vary with the type and timing of the restriction and the species studied. Maternal undernutrition before conception and/or in early pregnancy can alter fetal physiology in late gestation, and influence postnatal function, often without measurable effects on birth size. In contrast, to date, observational and intervention studies in humans provide limited support for a major role of maternal nutrition in determining birth size, except where women are quite malnourished. However, recent studies report associations between newborn size and the balance of macronutrients in women's diets in Western settings. Associations between maternal dietary composition and adult blood pressure of the offspring are also reported in human populations. Most studies in women have focused on dietary content or supplementation during mid-late pregnancy. Further investigation of how maternal dietary composition, before conception and throughout pregnancy, affects fetal physiology and health of the baby will increase the understanding of how maternal diet and nutritional status influence fetal, neonatal and longer-term outcomes.

To assess differences in congenital anomalies, infant mortality, and obstetrical complications as well as risk factors associated with an adverse pregnancy outcome in women with type 1 (T1DM) and type 2 diabetes mellitus (T2DM). This observational study was performed at a university clinic and included a total of 200 singleton pregnancies between January 1995 and December 2006. Outcome measures comprise the prevalence of major congenital malformations, fetal losses, stillbirths, and neonatal deaths as well as the combined end point, adverse pregnancy outcome, and obstetrical complications. Despite changes in prevailing risk factors, the rate of congenital anomalies and embryonic as well as perinatal death was comparable in type 1 diabetic women over time as well as between women with T1DM and T2DM. Outcome measures and risk factor profile were similar in women with preconception and newly diagnosed T2DM. Glycemic control and increased body mass index (BMI) during the first trimester were the strongest predictors of an adverse pregnancy outcome. Hemoglobin A1c (HbA1c) was higher in T1DM than in T2DM but similar in women with T1DM over time. BMI was highest in women with T2DM, followed by T1DM women of the most recent time period. In addition to HbA1c, other risk factors, especially high BMI, strongly influence pregnancy outcome. The higher prevalence of these risk factors in T2DM might compensate for the better glycemic control, resulting in a pregnancy outcome comparable to that of T1DM. Pregnancy outcome in T1DM remained unchanged over time, possibly because of the missing amelioration of HbA1c levels and the increasing BMI.

Biomarkers for Adverse Pregnancy Outcomes in Rheumatic Diseases.

PubMed

Soh, May Ching; Nelson-Piercy, Catherine

2017-05-01

Pregnancy is a delicate balance of angiogenic factors. Adverse pregnancy outcomes in the form of placental insufficiency occur when antiangiogenic factors predominate, which manifests as maternal-placental syndrome (MPS). Women with rheumatic disease are at increased risk of MPS. Endothelial damage from circulating antiangiogenic factors and other inflammatory molecules in combination with preexisting maternal vascular risk factors is the likely underlying pathophysiological process for MPS. It is likely that these changes persist, and additional "insults" from ongoing inflammation, medications, and disease damage contribute to the development of accelerated cardiovascular disease seen in young women with rheumatic disease.

The objectives are to report the estimated prevalence of pregnancy complications and adverse pregnancy outcomes in a defined population of Alaska Native women and also examine factors contributing to an intensive and successful collaboration between a tribal health center and the Centers for Disease Control and Prevention. Investigators abstracted medical record data from a random sample of singleton deliveries to residents of the study region occurring between 1997 and 2005. We used descriptive statistics to estimate the prevalence and 95% confidence intervals of selected pregnancy complications and adverse pregnancy outcomes. Records were examined for 505 pregnancies ending in a singleton delivery to 469 women. Pregnancy complication rates were 5.9% (95% CI 4.0, 8.4) for gestational diabetes mellitus, 6.1% (95% CI 4.2, 8.6%) for maternal chronic hypertension and 11.5% (95% CI 8.8, 14.6) for pregnancy associated hypertension, and 22.9% (95% CI 19.2-26.5 %) for anemia. The cesarean section rate was 5.5% (95% CI 3.5, 7.5) and 3.8% (95% CI 2.3, 5.8) of newborns weighed >4,500 g. Few previous studies reported pregnancy outcomes among Alaska Native women in a specific geographic region of Alaska and regarding the health needs in this population. We highlight components of our collaboration that contributed to the success of the study. Studies focusing on special populations such as Alaska Native women are feasible and can provide important information on health indicators at the local level.

Atrazine (ATR) is a commonly used agricultural herbicide that has been the subject of epidemiologic studies assessing its relation to reproductive health problems. This review evaluates both the consistency and the quality of epidemiologic evidence testing the hypothesis that ATR exposure, at usually encountered levels, is a risk factor for birth defects, small for gestational age birth weight, prematurity, miscarriages, and problems of fetal growth and development. We followed the current methodological guidelines for systematic reviews by using two independent researchers to identify, retrieve, and evaluate the relevant epidemiologic literature on the relation of ATR to various adverse outcomes of birth and pregnancy. Each eligible paper was summarized with respect to its methods and results with particular attention to study design and exposure assessment, which have been cited as the main areas of weakness in ATR research. As a quantitative meta-analysis was not feasible, the study results were categorized qualitatively as positive, null, or mixed. The literature on ATR and pregnancy-related health outcomes is growing rapidly, but the quality of the data is poor with most papers using aggregate rather than individual-level information. Without good quality data, the results are difficult to assess; however, it is worth noting that none of the outcome categories demonstrated consistent positive associations across studies. Considering the poor quality of the data and the lack of robust findings across studies, conclusions about a causal link between ATR and adverse pregnancy outcomes are not warranted. PMID:24797711

Preliminary evidence for associations between second-trimester human chorionic gonadotropin and unconjugated oestriol levels with pregnancy outcome in Down syndrome pregnancies.

Fifty-six cases of Down syndrome were identified in a population of women who had undergone maternal serum triple marker screening [alpha-fetoprotein (AFP), human chorionic gonadotropin (hCG), and unconjugated oestriol (uE3) analyses]. These affected pregnancies represented all known cases present in the population of 34,368 women screened. Using a 1:270 mid-trimester Down syndrome risk to define the screen-positive group, 42 affected pregnancies were screen-positive (medians: AFP = 0.79 MOM, hCG = 2.13 MOM, uE3 = 0.62 MOM, age 34.6 years) and 14 pregnancies were screen-negative (medians: AFP = 0.82 MOM, hCG = 1.57 MOM, uE3 = 0.92 MOM, age 24.2 years). Four affected pregnancies were associated with in utero death and each of these cases was associated with relatively extreme values of AFP, hCG, and uE3, including the three highest levels of hCG in the entire series of Down syndrome pregnancies. Twenty-nine (15 screen-positive and 14 screen-negative) affected pregnancies resulted in liveborns. Down syndrome pregnancies had a significantly shorter gestational term than controls, and Down syndrome babies were also lighter than controls, even after adjustment for sex and gestational age. In affected pregnancies, a low uE3 level appeared to be associated with a greater chance of a small-for-gestational age baby. No correlations could be demonstrated between AFP or hCG levels and gestational age-adjusted term weight. Based on this small series, it would appear that uE3 may be particularly useful in detecting those Down syndrome cases associated with small-for-gestational age fetuses. A very high hCG value may indicate a higher probability of fetal death.

CenteringPregnancy is a client-centered model of group prenatal care that brings women together into small groups to receive care through assessment, education, and support. As Spanish-speaking CenteringPregnancy groups become more common, outcomes of Latinas who attend these groups must be assessed. The purpose of this retrospective cohort study was to compare pregnancy outcomes of Latina women who completed CenteringPregnancy in a public health clinic with women who completed individual care in the same clinic during the same time. Medical charts were reviewed retrospectively to examine differences in pregnancy outcomes and maternal factors in both prenatal care groups. Latina Spanish-speaking women who completed CenteringPregnancy were matched with Latina Spanish-speaking women who completed individual care within the same time frame. Logistic regression analysis was conducted to examine maternal and birth outcomes. A total of 487 patient charts were obtained for data collection (CenteringPregnancy n = 247, individual n = 240). No differences in low-birth-weight or preterm births were observed between the groups. Compared with women in individual care, women in CenteringPregnancy had higher odds of giving birth vaginally (adjusted odds ratio [aOR], 2.57; 95% confidence interval [CI], 1.23-5.36), attending prenatal care visits (aOR, 11.03; 95% CI, 4.53-26.83), attending postpartum care visits (aOR, 2.20; 95% CI, 1.20-4.05), and feeding their infants formula only (aOR, 6.07; 95% CI, 2.57-14.3). Women in CenteringPregnancy also had lower odds of gaining below the recommended amount of gestational weight (aOR, 0.41; 95% CI, 0.22-0.78). Women in CenteringPregnancy had higher health care utilization, but there were no differences in preterm birth or low birth weight. Randomized studies are needed to eliminate selection bias. © 2013 by the American College of Nurse-Midwives.

While increased rheumatic disease activity during pregnancy has been associated with adverse pregnancy outcomes, this activity is typically assessed by the physician. Little is known, however, about the association between patient-reported measures of disease activity and pregnancy outcomes. Univariate and multivariable regression models were used to assess the relationship between patient and physician-reported measures of disease activity and adverse pregnancy outcomes in 225 patients with lupus or rheumatoid arthritis (RA) enrolled in a prospective registry at a single academic center from 2008-2016. In women with RA, patient-reported disease activity is associated with preterm birth (OR 5.9 (1.5-23.9)), and gestational age (beta -1.5 weeks (-2.6, -0.4 weeks)). The physician assessment of disease activity also predicted preterm (OR 2.1 (1.2-3.5)), small for gestational age births (OR 1.8 (1.03-3.1), and gestational age in weeks (beta -0.6 weeks (-0.9, -0.02 weeks)). On the other hand, SLE patient-reported disease activity measures, including the HAQ, pain or global health measures, are not associated with adverse pregnancy outcomes. However, physician measures of SLE disease activity are associated with preterm birth (OR 2.9 (1.-6.3)), cesarean delivery (OR 2.3 (1.0-5.3)), and preeclampsia (OR 2.8 (1.3-6.3)). The results do not appear to be driven by lupus nephritis or antiphospholipid syndrome. For women with RA, patient-reported measures of disease activity may be useful adjuncts to physician-reported measures in identifying pregnancies at greater risk. In contrast, in SLE, no patient-reported measures were associated with adverse outcomes while physician measures of disease activity helped predict several adverse pregnancy outcomes.

Acute viral hepatitis is the most common cause of jaundice in pregnancy. Amongst hepatitis E bears a deadly combination with pregnancy, leading to loss of very young lives. There is almost no data available in this aspect documenting prevalence, profile and effect of jaundice on outcome of pregnancy in Bangladesh. This observational study was done to determine and analyze the frequency, cause and outcome of jaundice in pregnancy among the admitted patients in the feto-maternal medicine wing of Bangabandhu Sheikh Mujib Medical University, for a 2 years period from August 2009 to July 2011. Management was done in collaboration with the hepatologists, hematologists and intensive care unit specialist. Outcome was noted in terms of the mode of delivery, maternal complications, need of blood transfusion and fresh frozen plasma and maternal end result. Fetal outcome was assessed by birth weight, Apgar score, neonatal admission, and perinatal mortality. Prevalence of jaundice was found 2.5% among all high risk and 1.3% among all obstetric admissions. Hepatitis E was the commonest cause and responsible for 80.4% cases of jaundice and next was cholestatic jaundice. Almost half of the patients (43.4%) faced complications like post partum haemorrhage (15.3%), hepatic encephalopathy (10.8%), ante partum hemorrhage (6.5%). Preterm delivery was noted in 71.1% cases. Out of 46 patients with jaundice four (4) mothers died due to hepatic encephalopathy in hepatitis E group. Regarding perinatal outcome 55.8% were of low birth weight, 35.3% had low Apgar score and perinatal mortality was 6.4%.

Concentrations of urinary steroids are measured in anti-doping test programs to detect doping with endogenous steroids. These concentrations are combined into ratios and followed over time in the steroidal module of the Athlete Biological Passport (ABP). The most important ratio in the ABP is the testosterone/epitestosterone (T/E) ratio but this ratio is subject to intra-individual variations, especially large in women, which complicates interpretation. In addition, there are other factors affecting T/E. Pregnancy, for example, is known to affect the urinary excretion rate of epitestosterone and hence the T/E ratio. However, the extent of this variation and how pregnancy affect other ratios has not been fully evaluated. Here we have studied the urinary steroid profile, including 19-norandrosterone (19-NA), in 67 pregnant women and compared to postpartum. Epitestosterone was higher and, consequently, the T/E and 5αAdiol/E ratios were lower in the pregnant women. Androsterone/etiocholanolone (A/Etio) and 5αAdiol/5βAdiol, on the other hand, were higher in the first trimester as compared to postpartum (p<0.0001 and p=0.0396, respectively). There was no difference in A/T during pregnancy or after. 19-NA was present in 90.5% of the urine samples collected from pregnant women. In this study, we have shown that the steroid profile of the ABP is affected by pregnancy, and hence can cause atypical passport findings. These atypical findings would lead to unnecessary confirmation procedures, if the patterns of pregnancy are not recognized by the ABP management units. Copyright © 2018 John Wiley & Sons, Ltd.

To identify risk factors for adverse pregnancy outcome in women with inflammatory bowel disease (IBD) and to assess the effect of maternal pre-pregnancy weight and weight gain during pregnancy on pregnancy outcome. A retrospective, matched control study of all gravid women with IBD treated in a single tertiary center. Data were compared with healthy controls matched to by age, parity and pre-pregnancy BMI in a 3:1 ratio. Overall, 300 women were enrolled, 75 women in the study group (28 with ulcerative colitis and 47 with Crohn's disease) and 225 in the control group. The rates of preterm delivery and small for gestational age were higher in the study group (13.3 vs. 5.3% p = 0.02 and 6.7 vs. 0.9%, p = 0.004). The rate of cesarean section (36 vs. 19.1%; p = 0.002), NICU admission (10.7 vs. 4.0%, p = 0.03) and low 5-Min Apgar (4.0 vs. 0.4%, p = 0.02) were increased in the study group. Disease activity within 3 months of conception [OR 8.4 (1.3-16.3)] and maternal weight gain of less than 12 kg. [OR 3.6 (1.1-12.2)] were associated with adverse pregnancy outcome. Active disease at conception and inappropriate weight gain during pregnancy are associated with increased adverse pregnancy outcome in patients with IBD.

The Alberta Pregnancy Outcomes and Nutrition (APrON) study is an ongoing prospective cohort study that recruits pregnant women early in pregnancy and, as of 2012, is following up their infants to 3 years of age. It has currently enrolled approximately 5000 Canadians (2000 pregnant women, their offspring and many of their partners). The primary aims of the APrON study were to determine the relationships between maternal nutrient intake and status, before, during and after gestation, and (1) maternal mood; (2) birth and obstetric outcomes; and (3) infant neurodevelopment. We have collected comprehensive maternal nutrition, anthropometric, biological and mental health data at multiple points in the pregnancy and the post-partum period, as well as obstetrical, birth, health and neurodevelopmental outcomes of these pregnancies. The study continues to follow the infants through to 36 months of age. The current report describes the study design and methods, and findings of some pilot work. The APrON study is a significant resource with opportunities for collaboration. © 2012 John Wiley & Sons Ltd.

Offspring Outcomes in Studies of Antidepressant-Treated Pregnancies Depend on the Choice of Control Group.

PubMed

Andrade, Chittaranjan

Antenatal depression complicates 14%-23% of pregnancies; if the depression is left untreated, there is an increased risk of a wide range of adverse maternal and offspring outcomes. However, antidepressant use, and, more specifically, selective serotonin reuptake inhibitor (SSRI) use, has also been associated with adverse pregnancy outcomes. Regrettably, SSRIs have received bad press in this context even though the evidence linking them with the adverse outcomes has not disentangled depression effects from drug effects. The most important reason why depression and drug effects cannot be separated is that the evidence is derived mostly from retrospective observational studies and not from randomized controlled trials, which are necessary but which cannot be performed during pregnancy for ethical and practical reasons. In these observational studies, the control groups are formed from healthy women, depressed women, and/or propensity score-matched women who did not receive antidepressant drugs during pregnancy. A limitation of such control groups is that they cannot control for confounding arising from poorly measured, unmeasured, or unknown variables that influence the pregnancy outcomes being assessed. This article discusses problems involved in such research and illustrates how, when confounding is diminished by using sibling controls discordant for antidepressant exposure during pregnancy, the risks of adverse outcomes associated with antidepressant exposure diminish. However, a discordant sibling control group is associated with its own limitations, and these are also discussed. © Copyright 2017 Physicians Postgraduate Press, Inc.

Cardiovascular outcomes of pregnancy in Marfan's syndrome patients: A literature review.

Pregnancy in patients with Marfan's syndrome (MFS) carries an increased risk of cardiovascular complications, resulting in increased maternal and fetal mortality and morbidity. Literature on MFS pregnant patients is relatively sparse, and there has yet to be a concrete consensus on the management of this unique patient population. The purpose of our paper is to provide a literature review of case reports and studies on MFS during pregnancy (published between 2005 and 2015) and to explore cardiovascular outcomes of patients with MFS. Of the 852 women in our review, there were 1112 pregnancies, with an aortic dissection rate of 7.9% and mortality of 1.2%. Data demonstrated a trend that patients whose aortic diameter ≥40 mm had a greater rate of dissection than MFS patients whose aortic diameter <40 mm (Fisher's exact test, P = .0504). Fetal outcome included a 5.6% mortality rate and 41% of births were cesarean deliveries and of those reported, 75% secondary to cardiac emergencies. Patients with MFS, especially those whose initial aortic diameters ≥40 mm, planning a pregnancy or currently pregnant should be carefully counseled about the maternal and fetal risks throughout pregnancy. MFS patients whose aortic diameters ≥40 mm should be advised to ideally await pregnancy until prophylactic aortic surgery. As MFS varies in its phenotypic expression, each patient's risk of adverse cardiac events should be assessed individually through a joint Maternal Fetal Medicine and Cardiology Center. © 2017 Wiley Periodicals, Inc.

Brucellosis is a zoonosis with high morbidity in humans. This disease has gained interest recently due to its re-emergence and potential for weaponization. Pregnant women with this disease can develop severe complications. Its association with adverse obstetric outcomes is not clearly understood. The objective of this study was to describe the obstetric outcomes of brucellosis in pregnancy. Cases of pregnant women with active brucellosis seen at the Hospital Nacional Cayetano Heredia from 1970 to 2012 were reviewed. Diagnostic criteria were a positive agglutination test and/or positive blood/bone marrow culture. Presentation and outcomes data were collected. The Chi-square test was used for nominal variables. A p-value of <0.05 indicated significance. One hundred and one cases were included; 27.7% had a threatened abortion/preterm labor, 12.8% experienced spontaneous abortion, 13.9% preterm delivery, 8.1% fetal death, and 1.1% congenital malformations. There was one maternal death secondary to severe sepsis. After delivery, neonatal death occurred in 8.1%, low birth weight in 14.5%, and congenital brucellosis in 6.4%. The most common treatment was aminoglycosides plus rifampicin (42.2% of cases). Complication rates decreased if treatment was started within 2 weeks of presentation (p < 0.001). This is the largest series of brucellosis in pregnancy reported in the literature. Brucella presents adverse obstetric outcomes including fetal and maternal/neonatal death. Cases with unexplained spontaneous abortion should be investigated for brucellosis. Prompt treatment is paramount to decrease the devastating outcomes. Copyright © 2015. Published by Elsevier Ltd.

To investigate the effect of pre-pregnancy BMI on adverse maternal and neonatal outcomes in pregnancy women of northern China. We conducted a retrospective population-based cohort study of 5,047 singleton nulliparous pregnancies. The subjects were categorized into four groups by BMI-underweight (BMI < 18.5 kg/m(2)), normal (BMI 18.5-24 kg/m(2)), overweight (BMI 24-28 kg/m(2)) and obese (BMI ≥ 28 kg/m(2)). Logistic regression was used to adjust the potential confounder. Maternal and neonatal outcomes were evaluated with relative risks and 95% confidence intervals. 11.5, 63.4, 18.3, and 6.8% of the subjects were underweight, normal BMI, overweight and obese, respectively. Compared with women of normal BMI, the risk of the following outcomes was significantly increased in overweight and obese women and expressed as [adjusted RR (95% confidence interval)] respectively: pre-eclampsia [2.99 (2.21-4.06), 5.68 (3.97-8.11)]; gestational diabetes [2.49 (1.82-3.39), 4.35 (3.00-6.31)]; premature rupture of the membranes [1.64 (1.20-2.23), 1.73 (1.11-2.72)]; abruption placentae [1.84 (1.19-2.87), 2.79 (1.60-4.83)]; cesarian section [1.47 (1.27-1.70), 2.51 (1.97-3.20)]; postpartum hemorrhage [2.31 (1.51-3.54), 3.73 (2.37-5.04)]; perineal rupture [2.89 (1.44-5.81), 3.36 (1.55-7.30)]; large-for-gestational age [1.46 (1.02-2.08), 1.91 (1.17-3.10)]. However, anemia (2.54, 1.15-5.63), small-for-gestational age (1.67, 1.07-2.61) were significantly more common in the underweight group. The prevalence of overweight and obesity in women of northern China is much lower than in the Caucasian population or Chinese in Hong Kong. The increased maternal BMI is associated with many adverse pregnancy outcomes and its risk increases with the degree of obesity. Maternal underweight has a protective effect although increases the risk of having small-for-gestational age baby and anemia.

Pregnancy and alcohol use: evidence and recommendations for prenatal care.

PubMed

Bailey, Beth A; Sokol, Robert J

2008-06-01

Pregnancy alcohol consumption has been linked to poor birth outcomes and long-term developmental problems. Despite this, a significant number of women drink during pregnancy. Although most prenatal care providers are asking women about alcohol use, validated screening tools are infrequently employed. Research has demonstrated that currently available screening methods and intervention techniques are effective in identifying and reducing pregnancy drinking. Implementing universal screening and appropriate intervention for pregnancy alcohol use should be a priority for prenatal care providers, as these efforts could substantially improve pregnancy, birth, and longer term developmental outcomes for those affected.

The results of medical treatment for early pregnancy failure are conflicting. To determine whether gestational sac volume measurement as well as other variables can predict the success rate of medical treatment for early pregnancy failure. The study group comprised 81 women diagnosed with missed abortion or anembryonic pregnancy who consented to medical treatment. Demographic data were collected and beta-human chorionic gonadotropin level was documented. Crown-rump length and the sac volume were measured using transvaginal ultrasound. TVU was performed 12-24 hours after intravaginal administration of 800 micro g misoprostol. If the thickness of the uterine cavity was less than 30 mm, the women were discharged. If the sac was still intact or the thickness of the uterine cavity exceeded 30 mm, they were offered an additional dosage of intravaginal misoprostol or surgical uterine evacuation. Medical treatment successfully terminated 32 pregnancies (39.5%), 30 after one dose of misoprostol and 2 after two doses (group A); 49 underwent surgical evacuation (group B), 47 following one dose of misoprostol and 2 following two doses. There were no significant differences between the groups in age and gestational week. Gestational sac volume did not differ between groups A and B (10.03 and 11.98 ml respectively, P = 0.283). Parity (0.87 and 1.43, P = 0.015), previous pregnancies (2.38 and 2.88, P = 0.037), and betahCG concentration (6961 and 28,748 mlU, P = 0.013) differed significantly between the groups. Gestational sac volume is not a predictor of successful medical treatment for early pregnancy failure. Previous pregnancies and deliveries and higher betahCG concentration negatively affect the success rate of medical treatment.

Biomarkers used in studying air pollution exposure during pregnancy and perinatal outcomes: a review.

This review focuses on studies among pregnant women that used biomarkers to assess air pollution exposure, or to understand the mechanisms by which it affects perinatal outcomes. We searched PubMed and Google scholar databases to find articles. We found 29 articles, mostly consisting of cohort studies. Interpolation models were most frequently used to assess exposure. The most consistent positive association was between polycyclic aromatic hydrocarbon (PAH) exposure during entire pregnancy and cord blood PAH DNA adducts. Exposure to particulate matter (PM) and nitrogen dioxide (NO 2 ) showed consistent inverse associations with mitochondrial DNA (mtDNA) content, particularly in the third trimester of pregnancy. No single pollutant showed strong associations with all the biomarkers included in this review. C-reactive proteins (CRPs) and oxidative stress markers increased, whereas telomere length decreased with increasing air pollution exposure. Placental global DNA methylation and mtDNA methylation showed contrasting results with air pollution exposure, the mechanism behind which is unclear. Most studies except those on PAH DNA adducts and mtDNA content provided insufficient evidence for characterizing a critical exposure window. Further research using biomarkers is warranted to understand the relationship between air pollution and perinatal outcomes.

Home visits during pregnancy: consequences on pregnancy outcome, use of health services, and women's situations.

Blondel, B; Bréart, G

1995-08-01

This review of eight randomized controlled trials assessed two different types of home visits during pregnancy: (1) those offering social support to high-risk women; and (2) those providing medical care to women with complications. In both categories, pregnancy outcome was not improved when women received home visits. The summary odds ratio for preterm delivery (< 37 weeks) was 1.0 (95% CI: 0.8 to 1.1). Nor did the home visits decrease the rate of hospital admission for women with complications (mainly threatened preterm labor or toxemia); the corresponding summary odds ratio was 0.9 (95% CI: 0.7 to 1.2). Nevertheless in some trials home visits had positive effects on women (medical knowledge, support levels, health habits, and satisfaction). The randomized controlled trials provide little evidence that programs offering home visits are effective in improving either pregnancy outcome or the use of health services. A better integration of hospital and home services might allow a more rational use of health services for women with complications. In addition, we need to define more precisely the content of home visits providing social support. For this, further research is required on how emotional support, health education, and advice influence the health of women and infants and mother-child interactions.

reduction of physical activity (PA) during pregnancy is common but undesirable, as it is associated with negative outcomes, including excessive gestational weight gain. Our objective was to explore changes in five types of activity that occurred during pregnancy and the behavioural determinants of the reported changes in PA. we performed a secondary analysis of a cross sectional survey that was constructed using the ASE-Model - an approach to identifying the factors that drive behaviour change that focuses on Attitude, Social influence, and self-Efficacy. 455 healthy pregnant women of all gestational ages, receiving prenatal care from midwifery practices in the Netherlands. more than half of our respondents reported a reduction in their PA during pregnancy. The largest reduction occurred in sports and brief rigorous activities, but other types of PA were reduced as well. Reduction of PA was more likely in women who considered themselves as active before pregnancy, women who experienced pregnancy-related barriers, women who were advised to reduce their PA, and multiparous women. Fewer than 5% increased their PA. Motivation to engage in PA was positively associated with enjoying PA. all pregnant women should be informed about the positive effects of staying active and should be encouraged to engage in, or to continue, moderately intensive activities like walking, biking or swimming. Our findings concerning the predictors of PA reduction can be used to develop an evidence-based intervention aimed at encouraging healthy PA during pregnancy. Copyright © 2017 Elsevier Ltd.

To evaluate whether socioeconomic variables influence the management and outcomes of ectopic pregnancies. Retrospective cohort study (Canadian Task Force classification II-2). Hospitals in the United States participating in the Health Care Cost and Utilization Project. Women (n = 35 535) with a primary discharge diagnosis of ectopic pregnancy. Effect of socioeconomic factors and race/ethnicity on management and adverse outcomes of ectopic pregnancy. During the 9-year study, 35 535 ectopic pregnancies were identified. The development of hemoperitoneum in 8706 patients (24.50%) was the most common complication. Asian race was the sociodemographic variable most predictive of hemoperitoneum (odds ratio [OR], 1.41; 95% confidence interval [CI], 1.24-1.61; p < .01) and transfusion (OR, 1.62; 95% CI, 1.39-1.89; p < .01), and Medicare status was most influential on prolonged hospitalization (OR, 1.83; 95% CI, 1.36-2.47; p < .01). Major complications were not affected by socioeconomic factors. Laparotomy in 25 075 patients (70.6%) was the most common treatment option. Patients of Asian or Pacific Islander descent were least likely to be treated non-surgically (OR, 0.62; 95% CI, 0.51-0.76; p < .01), whereas Medicare recipients were most likely to be treated non-surgically (OR, 1.70; 95% CI, 1.32-2.18; p < .01). All non-white groups were less likely to undergo a laparoscopic approach. Major complications from ectopic pregnancy are not influenced by socioeconomic variables; however, less serious complications and management approaches are persistently affected.

To examine the relationship of police-reported intimate partner violence during pregnancy and adverse birth outcomes. We conducted a population-based, retrospective, cohort study in Seattle, Washington, using Seattle police data and Washington State birth certificate files from January 1995 through September 1999. Exposed subjects were women with an intimate partner violence incident reported to police during pregnancy and who subsequently had a singleton live birth or fetal death registered in the state of Washington. Unexposed subjects were randomly selected Seattle residents with a singleton live birth or fetal death in the same time period and who did not report an incident. The main outcome measures were low birth weight (LBW less than 2500 g), very LBW (VLBW less than 1500 g), preterm birth (20-36 weeks' gestation), very preterm birth (20-31 weeks), and neonatal death (before discharge). Women reporting any partner violence during pregnancy were significantly more likely to have a LBW infant (adjusted odds ratio [aOR] 1.70; 95% confidence interval [CI] 1.20, 2.40), a VLBW infant (aOR 2.54; 95% CI 1.32, 4.91), a preterm birth (aOR 1.61; 95% CI 1.14, 2.28), a very preterm birth (aOR 3.71; 95% CI 1.80, 7.63), and a neonatal death (aOR 3.49; 95% CI 1.43, 8.50). Police-reported partner violence during pregnancy is significantly associated with an increased risk of adverse birth outcomes. There is a critical need to identify pregnancy among women with reported incidents and to provide women health and social service information and referrals, particularly referrals to high-risk pregnancy programs.

Cytolytic recognition of CMV-infected syngeneic fetal guinea pig cells by maternal peripheral blood mononuclear cells (PBMC) was suppressed late in pregnancies of uninfected guinea pig breeders with less than 25% conceptus loss. A small subset of less successful uninfected pregnancies with greater than or equal to 50% fetal wastage exhibited only partial suppression of cytolytic activity against CMV-infected fetal cells. Primary CMV infection of dams extending into early pregnancy induced augmented cytolysis of CMV-infected fetal cells, but not MA104 NK cell targets, throughout gestation and resulted in 70% loss of conceptus. Decreased suppression of cytolytic activity against CMV-infected fetal cells in uninfected pregnancy was also associated with runting of newborn pups, which was not as severe as that observed in congenitally CMV-exposed or CMV-infected pups. Congenitally infected pups were affected more than their exposed but uninfected litter mates. Lack of suppression of cytolysis of CMV-infected syngeneic fetal cells, whether spontaneous or CMV-infection-induced, appears to be associated with poor pregnancy outcome.

Smoking and pregnancy.

Abel, E L

1984-01-01

Smoking during pregnancy is associated with many adverse outcomes, including fetal and neonatal death. These consequences are tragic in many ways, but perhaps the greatest tragedy is that they are preventable if the smoker ceases to smoke during pregnancy. Although in some instances the so-called constitutional hypothesis is difficult to disprove, the available evidence seems more than convincing that it is smoking itself, and not the smoker's unique constitution, that is responsible. Cessation from smoking is clearly advisable at any time, but more so during pregnancy when every cigarette affects both the smoker and her unborn child.

Impact of malaria during pregnancy on pregnancy outcomes in a Ugandan prospective cohort with intensive malaria screening and prompt treatment

PubMed Central

2013-01-01

Background Malaria in pregnancy (MiP) is a major public health problem in endemic areas of sub-Saharan Africa and has important consequences on birth outcome. Because MiP is a complex phenomenon and malaria epidemiology is rapidly changing, additional evidence is still required to understand how best to control malaria. This study followed a prospective cohort of pregnant women who had access to intensive malaria screening and prompt treatment to identify factors associated with increased risk of MiP and to analyse how various characteristics of MiP affect delivery outcomes. Methods Between October 2006 and May 2009, 1,218 pregnant women were enrolled in a prospective cohort. After an initial assessment, they were screened weekly for malaria. At delivery, blood smears were obtained from the mother, placenta, cord and newborn. Multivariate analyses were performed to analyse the association between mothers’ characteristics and malaria risk, as well as between MiP and birth outcome, length and weight at birth. This study is a secondary analysis of a trial registered with ClinicalTrials.gov, number NCT00495508. Results Overall, 288/1,069 (27%) mothers had 345 peripheral malaria infections. The risk of peripheral malaria was higher in mothers who were younger, infected with HIV, had less education, lived in rural areas or reported no bed net use, whereas the risk of placental infection was associated with more frequent malaria infections and with infection during late pregnancy. The risk of pre-term delivery and of miscarriage was increased in mothers infected with HIV, living in rural areas and with MiP occurring within two weeks of delivery. In adjusted analysis, birth weight but not length was reduced in babies of mothers exposed to MiP (−60g, 95%CI: -120 to 0 for at least one infection and -150 g, 95%CI: -280 to −20 for >1 infections). Conclusions In this study, the timing, parasitaemia level and number of peripherally-detected malaria infections, but not the

adjusted for weight gain, the increased efficiency is maintained throughout the pregnancy, with the improvement being greater in exercising women. Regular physical activity has been proven to result in marked benefits for mother and fetus. Maternal benefits include improved cardiovascular function, limited pregnancy weight gain, decreased musculoskeletal discomfort, reduced incidence of muscle cramps and lower limb oedema, mood stability, attenuation of gestational diabetes mellitus and gestational hypertension. Fetal benefits include decreased fat mass, improved stress tolerance, and advanced neurobehavioural maturation. In addition, few studies that have directly examined the effects of physical activity on labour and delivery indicate that, for women with normal pregnancies, physical activity is accompanied with shorter labour and decreased incidence of operative delivery. However, a substantial proportion of women stop exercising after they discover they are pregnant, and only few begin participating in exercise activities during pregnancy. The adoption or continuation of a sedentary lifestyle during pregnancy may contribute to the development of certain disorders such as hypertension, maternal and childhood obesity, gestational diabetes, dyspnoea, and pre-eclampsia. In view of the global epidemic of sedentary behaviour and obesity-related pathology, prenatal physical activity was shown to be useful for the prevention and treatment of these conditions. Further studies with larger sample sizes are required to confirm the association between physical activity and outcomes of labour and delivery.

The 2014 report by European Medicines Agency (EMA) restricted the use of thiocolchicoside for all reproductive-age women. In this study, we aim to expand the systematically-collected human data and discuss it within the frame provided by this report. We identified and evaluated the outcomes of 48 prospectively recorded pregnancies referred to Terafar (Teratology Information Service, Izmir, Turkey). Of 42 pregnancies with first-trimester exposure and known outcomes, 31 resulted in live births, four in miscarriage and seven ended with elective terminations. There were 26 normal outcomes, two major and three minor congenital malformations among the live births. Despite a number of limitations, our results and previous case series collectively strengthen the view that thiocolchicoside is unlikely to be a major teratogen. EMA's 2014 report should be revised to reflect this finding, while current restrictions on use should continue until more detailed safety information is available. Copyright © 2018 Elsevier Inc.

Several studies have demonstrated that fetal gender has a significant effect on the pregnancy outcomes and pregnancy-related complications. However, results differ as the race and population changes. The aim of our study was to test whether the recorded phenomenon of adverse pregnancy outcomes associated with a male fetus applies to women in northern China. This was a multi-centered, cross-sectional study. The study population included women who delivered babies in 25 different hospitals in 9 provinces in northern China, from 1 January 2011 to 31 December 2011. For our analysis, we selected 65 173 singleton birth deliveries at or after 28 weeks that occurred during the year 2011. Male fetal gender was associated with an increased incidence of preterm delivery (8.33% for males; 7.19% for females), gestational diabetes mellitus (4.58% for males; 4.26% for females), fetal macrosomia (9.41% versus 5.78%), lower Apgar score (2.05% versus 1.78%), perinatal death (0.92% versus 0.76%), placenta previa (0.95% versus 0.81%), increased cesarean section delivery (54.87% versus 52.31%) and operative delivery (1.34% versus 1.19%) (p < 0.05). However, female fetuses were associated with an increased risk of preeclampsia at an advanced gestational age (15.86% for males; 17.53% for females), fetal growth restriction (0.74% for males; 1.09% for females), malpresentation (3.6% for males; 4.31% for females), postpartum hemorrhage (2.92% for males; 3.19% for females) (p < 0.05). The recorded phenomenon of adverse pregnancy outcomes associated with a male fetus applies to our population regardless of some different results.

Uterine Fibroid Embolisation – Potential Impact on Fertility and Pregnancy Outcome

PubMed Central

David, M.; Kröncke, T.

2013-01-01

The current standard therapy to treat myomas in women wishing to have children consists of minimally invasive surgical myomectomy. Uterine artery embolisation (UAE) has also been discussed as another minimally invasive treatment option to treat myomas. This review evaluates the literature of the past 10 years on fibroid embolisation and its impact on fertility and pregnancy. Potential problems associated with UAE such as radiation exposure of the ovaries, impairment of ovarian function and the impact on pregnancy and child birth are discussed in detail. Previously published reports of at least 337 pregnancies after UAE were evaluated. The review concludes that UAE to treat myomas can only be recommended in women with fertility problems due to myomas who refuse surgery or women with an unacceptably high surgical risk, because the evaluated case reports and studies show that UAE significantly increases the risk of spontaneous abortion; there is also evidence of pathologically increased levels for other obstetric outcome parameters. There are still very few prospective studies which provide sufficient evidence for a definitive statement on the impact of UAE therapy on fertility rates and pregnancy outcomes. PMID:26633901

The aim of study was to compare some perinatal outcomes in mothers with type 1 diabetes mellitus (T1DM). All patients with T1DM delivered at the 1st Department of Obstetrics and Gynaecology of Faculty of Medicine, Comenius University in Bratislava from January 1st 2009 to December 31th 2015 were included to the study. Out of 118 diabetic mothers, 46.6 % had vasculopathy and 53. 4 % were without microvascular complications. In the vasculopathy group, significantly higher incidence rates of preeclampsia (49. 1 versus 19.1 %; p = 0.002) and caesarean section (89.1 versus 68.3 %; p = 0.017) were found. Neonatal morbidity and mortality rates were higher in vasculopathy group (but not statistically significantly). Preparation for pregnancy improves perinatal and neonatal results. Nevertheless, this preparation in our study group was received only in 9.3 %. Perinatal mortality was 25.4 per 1,000 total births. For pregnancy of diabetic women to become possible a qualified management must be provided. Good outcomes for both women and newborns are real when preparation for pregnancy and metabolic control before and during whole pregnancy are at adequate level (Tab. 3, Ref. 28).

To determine the contribution of drug use to maternal and perinatal complications, controlling for social confounders. This is a retrospective cohort study of 247 drug-using women and 741 controls over a 4-year period from 1997 to 2000. Cases were identified from the drug dependency register. Three controls for each woman with substance abuse were selected from the delivery suite records, with calliper matching by year of delivery (any control patient who delivered within 6 months before or after the date of delivery of a drug-using woman was considered as a potential match) and district of residence (post code). The primary outcomes of interest were preterm birth, abruption, pre-eclampsia, intrauterine growth restriction and low birth weight. There were statistically significantly more preterm births amongst drug-using women (relative risk (RR) 2.5, 95% confidence interval (CI) 1.6-3.8), with preterm births complicating 25% of births amongst drug users. The incidence of low birth weight was 30.8% amongst drug-using women compared to 8% in control women (RR 3.6, CI 2.4-5.4), and the incidence of growth restriction was 25%, significantly higher than the control group (RR 3.82, CI 2.4-6.1). The risk of abruption was also higher (RR 2.74, CI 1.1-7.0). Of note is the extremely low incidence of pre-eclampsia among drug users, even after controlling for the confounder effects of parity and smoking. Despite multidisciplinary co-ordinated antenatal care, women with substance abuse during pregnancy are at significant risk of adverse obstetric and perinatal outcome, controlling for social confounders. A limitation of the study is that the sample size was not large enough to clearly assess individual drugs. This is the first study to highlight low incidence of pre-eclampsia among drug users over and above the effect of smoking. Further research is needed to elucidate the underlying biological reason for the lack of pre-eclampsia in women with substance abuse during pregnancy

To determine the etiology, clinical features and outcome of fulminant hepatic failure in pregnancy. An observational hospital based study was conducted at Isra University hospital Hyderabad from 1st March 2009 to 28th February 2010. Total 1192 obstetric patients were admitted in obstetrics & gynaecology department during this period, of whom 52 were with Fulminant hepatic failure in pregnancy and were included in this study. A pre-designed structured proforma was used. All patients had clinical history and underwent a physical examination. Routine laboratory tests, liver function tests and viral serology were performed in all cases. All results were analyzed on statistical software SPSS version 11. Frequencies and percentages were calculated, the final outcome was recorded. Out of 52, 6 (11.5%) presented in the first trimester, 4 (7.6%) in the second trimester and 42 (80.7%) were in their 3rd trimester of pregnancy. Etiology of the disease was Hepatitis E in 28 (53.8%), Hepatitis B in 9 (17.3%), Hepatitis C in 7 (13.5%) HELLP syndrome in 7 (13.5%) and acute fatty liver of pregnancy in 1 (3.57%) case. Maternal mortality was 15 (28.8%) and foetal mortality was 40 (77%). Only 12 (23.1%) new born remained alive. Fulminant hepatic failure in pregnancy has very high foetal and maternal mortality which is mostly due to viral hepatitis E.

To determine whether or not a previous abortion has a deleterious effect on the outcome of a subsequent pregnancy, 6443 delivery records at Ramathibodi hospital between January and December 1982 were reviewed. The 2 study groups consisted of 143 women who had previously had an induced abortion and 315 women who had previously had a spontaneous abortion. Control groups were women having a 2nd child after a normal 1st pregnancy. The 1st study group had fewer women under 19 and over 35 and a lower educational level. Group 2 had more women with a pregnancy interval of less than 2 years. There was no difference between the study groups and the controls in premature rupture of fetal membranes, placenta previa, cesarean sections, manual removal of placenta, retained secundine, postpartum hemorrhage, low birth weight, Apgar score less than 6, congenital abnormalities, or perinatal mortality. The only difference between both study groups and the controls was that there was a higher percentage of assisted deliveries in both study groups. This finding is probably the result of the fact that these were 1st births and is totally unrelated to previous abortion.

Acute pancreatitis in pregnancy is a rare and dangerous disease. This study aimed to examine the etiology, treatment, and outcomes of pancreatitis in pregnancy. A total of 25 pregnant patients diagnosed with pancreatitis during the period of 1994 and 2014 was analyzed retrospectively. The pregnant patients were diagnosed with pancreatitis during a period of 21 years. Most (60%) of the patients were diagnosed with pancreatitis in the third trimester. The mean age of the patients at presentation was 25.7 years, with a mean gestational age of 24.4 weeks. Abdominal pain occurred in most patients and vomiting in one patient was associated hyperemesis gravidarum. The common cause of the disease was gallstone-related (56%), followed by alcohol-related (16%), post-ERCP (4%), hereditary (4%) and undetermined conditions (20%). The level of triglycerides was minimally high in three patients. ERCP and wire-guided sphincterotomy were performed in 6 (43%) of 14 patients with gallstone-related pancreatitis and elevated liver enzymes with no complications. Most (84%) of the patients underwent a full-term, vaginal delivery. There was no difference in either maternal or fetal outcomes after ERCP. Acute pancreatitis is rare in pregnancy, occurring most commonly in the third trimester, and gallstones are the most common cause. When laparoscopic cholecystectomy is not feasible and a common bile duct stone is highly suspected on imaging, endoscopic sphincterotomy or stenting may help to prevent recurrence and postpone cholecystectomy until after delivery.

To define the outcomes and risk predictors of fetal and maternal consequences of pregnancy in lupus nephritis (LN) patients. Maternal and fetal outcomes of pregnancy in 52 systemic lupus erythematosus (SLE) patients were observed. Patients were allocated into two groups according to the presence or absence of LN. LN patients were subject to a higher risk of fetal complications, including fetal loss (7/24, 29.2 %, P = 0.001), lower birth weight (2548.2 ± 540.8 vs. 2949.1 ± 592.6 g, P = 0.028) and a higher frequency of small for gestational age births (33.3 vs. 10.7 %, P = 0.002). Higher rates of lupus flares (83.3 vs. 21.4 %, P = 0.001) and increased LAI-P scores (0.65 ± 0.36 vs. 0.21 ± 0.27, P = 0.001) during pregnancy were observed in LN patients. Multivariate analysis showed that increased SLE activity (P = 0.02, OR 4.2, 95 % CI 1.2-14.5), renal damage (P = 0.001, OR 8.4, 95 % CI 2.2-31.8), hypocomplementemia (P = 0.05, OR 3.23, 95 % CI 1.0-10.7), hypoalbuminemia (P = 0.011, OR 5.62, 95 % CI 1.4-23.0) and hypertension (P = 0.021, OR 6.0, 95 % CI 1.5-24.2) during pregnancy were predictors of adverse fetal outcomes. Pregnancy in LN patients should be monitored before and during pregnancy because of poor fetal and maternal outcomes. Increased LAI-P scores, renal damage, hypocomplementemia, hypoalbuminemia and hypertension are predictors of adverse fetal outcomes for SLE patients.

Women are seriously subjected to psychiatric diseases during pregnancy and depression is the most prevailing one among these diseases. There is a relation between the social support and depression in pregnancy whose predisposing factors are genetic, psychological, biological, environmental, and hormonal. This study aimed to determine the frequency of depression symptoms, and its risk factors. Also it studied the correlation between social support and pregnancy depression. This research is a descriptive cross-sectional study. It was conducted on 266 pregnant women selected by simple random method from all pregnant women admitted at the Maternity Hospital of Trabzon, Turkey from May 21 to June 13, 2008. The data were collected with a questionnaire form, the Beck depression inventory (BDI), and the multidimensional scale of perceived social support (MSPSS). The mean BDI score of the pregnant women was 11.12 ± 6.65. According to the BDI, 46.2% of the pregnant women had no depression symptoms, 34.59% of them had mild, 13.91% had moderate, and 4.89% had severe level of depression symptoms. It was found that such factors as the educational level of the pregnant women and their husbands, having an undesired pregnancy, suffering from a chronic disease before pregnancy, presence of pregnancy-related problems, having a child with disability or having relatives whose children had disability, and smoking during pregnancy were the risk factors affecting the severity of the depression symptoms and these results were statistically significant (P < 0.05). On the other hand, the mean MSPSS score was 67.89 ± 14.26 and it was found that the pregnant women got the highest social support from their husbands. It was found that there was a significant correlation between BDI and MSPSS total score and its subscale scores (P < 0.05). According to this study, one-fifth of pregnant women were found to experience depressive symptoms, which require treatment during pregnancy, and the factors

Recent studies have shown that gingivitis and periodontal infection during pregnancy represent an independent risk factor for pre-term birth. However, little is known about the prevalence and correlates of dental attendance during pregnancy. During the first 3 days postpartum, an anonymous questionnaire was administered to 425 women in order to explore their dental condition and utilisation of dental health services during pregnancy, as well as their perceptions on the potential associations between dental care during pregnancy and pregnancy outcomes. Almost half of the respondents (46.8%) reported symptoms of gingivitis during their pregnancy. Pregnancy gingivitis was independently associated with non-Greek ethnicity (p=0.008), multiparity versus primiparity (p<0.005), lower economic class versus middle and upper classes (p=0.001), and the lack of routine primary dental care (p=0.005). Some 27.3% reported a visit to the dentist during their pregnancy. The majority (72.2%) believed that dental treatment during pregnancy might have a negative affect on pregnancy outcome. The presence of pregnancy gingivitis and the belief that dental treatment during pregnancy is safe were both independently associated with visiting a dentist during pregnancy (p<0.0005 for both). Despite the increased prevalence of dental problems among pregnant women, few women seek dental services in this population, which can be primarily attributed to women's erroneous beliefs regarding the safety of dental examination. Therefore, there is an imperative need to offer oral health education and develop preventive programs for women of reproductive age.

To investigate and analyze the perinatal outcomes of low birth weight (LBW) infants, thereby selecting the appropriate mode and suitable time of delivery to improve the adverse pregnancy outcomes. A retrospective analysis of 112,441 deliveries (from 39 hospitals of different levels in 14 provinces and autonomous regions in China throughout 2011) were performed in this study to further evaluate the modes of delivery and pregnancy outcomes of LBW infants. The rate of cesarean section, stillbirth, neonatal asphyxia and mortality of LBW were significantly higher than those of normal birth weight (NBW) infants (odds ratio, 1.24, 56.56, 57.27 and 10.40 times higher, respectively). Stratified analysis showed that adverse events were reduced with the increase in gestational weeks, especially at 34 to 36(+6) weeks. However, LBW infants still had higher risks of adverse events as compared with NBW infants. In particular, full-term LBW babies had a 23.81- and 26.06-fold higher risk of stillbirth and neonatal death as compared with term babies with NBW. In addition, the cesarean delivery rate was 1.24-fold higher for LBW babies than for NBW babies. With an increase in gestational age in LBW infants, the rate of cesarean section was also increased. The rates of stillbirth and neonatal mortality of full-term LBW infants who were delivered via cesarean section (0.5% and 1.0%, respectively) were significantly lower than in the vaginal-delivery group (5.2% and 6.9%, respectively). LBW is one of the causes of perinatal death and other adverse pregnancy outcomes and increases the rate of cesarean section. Individualized analysis according to gestational age and intrauterine fetal condition should be performed to extend the gestational age to at least 34 weeks before delivery, cesarean section is a relatively safe mode of delivery, but cannot completely eliminate complications. The key to improving mother and child outcomes is to strengthen pregnancy care and reduce low birth weight

This report presents national estimates of pregnancies and pregnancy rates according to women's age, race, and Hispanic origin, and by marital status, race, and Hispanic origin. Data are presented for 1976-96. Data from the National Survey of Family Growth (NSFG) are used to show information on sexual activity, contraceptive practices, and infertility, as well as women's reports of pregnancy intentions. Tables of pregnancy rates and the factors affecting pregnancy rates are presented and interpreted. Birth data are from the birth-registration system for all births registered in the United States and reported by State health departments to NCHS; abortion data are from The Alan Guttmacher Institute (AGI) and the National Center for Chronic Disease Prevention and Health Promotion, Centers for Disease Control and Prevention (CDC); and fetal loss data are from pregnancy history information collected in the NSFG. In 1996 an estimated 6.24 million pregnancies resulted in 3.89 million live births, 1.37 million induced abortions, and 0.98 million fetal losses. The pregnancy rate in 1996 was 104.7 pregnancies per 1,000 women aged 15-44 years, 9 percent lower than in 1990 (115.6), and the lowest recorded since 1976 (102.7). Since 1990 rates have dropped 8 percent for live births, 16 percent for induced abortions, and 4 percent for fetal losses. The teenage pregnancy rate has declined considerably in the 1990's, falling 15 percent from its 1991 high of 116.5 per 1,000 women aged 15-19 years to 98.7 in 1996. Among the factors accounting for this decline are decreased sexual activity, increases in condom use, and the adoption of the injectable and implant contraceptives.

Fluoroquinolones are avoided during pregnancy due to developmental toxicity in animals. The aim of this study was to assess the fetal risk after intrauterine fluoroquinolone exposure. We performed an observational study of a prospectively ascertained cohort of pregnant women exposed to a fluoroquinolone during the first trimester. Pregnancy outcomes were compared to those of a cohort exposed to neither fluoroquinolones nor teratogenic or fetotoxic drugs. The outcomes evaluated were major birth defects (structural abnormalities of medical, surgical, or cosmetic relevance), spontaneous abortion, and elective termination of pregnancy. Pregnancy outcomes of 949 women with fluoroquinolone treatment were compared with those of 3,796 nonexposed controls. Neither the rate of major birth defects (2.4%; adjusted odds ratio [ORadj], 0.91; 95% confidence interval [CI], 0.6 to 1.5) nor the risk of spontaneous abortion (adjusted hazard ratio [HRadj], 1.01; 95% CI, 0.8 to 1.3) was increased. However, there was a nonsignificant increase in major birth defects after exposure to moxifloxacin (6/93, 6.5%; crude odds ratio [ORcrude], 2.40; 95% CI, 0.8 to 5.6). Neither a critical exposure time window within the first trimester nor a specific pattern of birth defects was demonstrated for any of the fluoroquinolones. The rate of electively terminated pregnancies was increased among the fluoroquinolone-exposed women (HRadj, 1.32; 95% CI, 1.03 to 1.7). The gestational ages at delivery and birth weights did not differ between groups. Our study did not detect an increased risk of spontaneous abortion or major birth defects. These reassuring findings support the recommendation to allow fluoroquinolone use in early pregnancy in selected cases. After the use of moxifloxacin, a detailed fetal ultrasound examination should be considered. PMID:24841264

To estimate the incidence of first pregnancy in women living with perinatally acquired HIV (PHIV) in the United Kingdom and to compare pregnancy management and outcomes with age-matched women with behaviourally acquired HIV (BHIV). The National Study of HIV in Pregnancy and Childhood is a comprehensive, population-based surveillance study that collects demographic and clinical data on all pregnant women living with HIV, their children, and all HIV-infected children in the United Kingdom and Ireland. The incident rate ratio of first pregnancy was calculated for all women of reproductive age who had been reported to the National Study of HIV in Pregnancy and Childhood as vertically infected children. These women and their pregnancies were compared to age-matched pregnant women with BHIV. Of the 630 women with PHIV reported in the United Kingdom as children, 7% (45) went on to have at least one pregnancy, with 70 pregnancies reported. The incident rate ratio of first pregnancy was 13/1000 woman-years. The BHIV comparison group comprised 118 women (184 pregnancies). Women with PHIV were more likely to be on combined antiretroviral therapy at conception and have a lower baseline CD4 cell count (P < 0.01 for both). In adjusted analysis, PHIV and a low baseline CD4 cell count were risk factors for detectable viral load near delivery; older age at conception and being on combined antiretroviral therapy at conception reduced this risk. Women with PHIV in the United Kingdom have a low pregnancy incidence, but those who become pregnant are at risk of detectable viral load near delivery, reflecting their often complex clinical history, adherence, and drug resistance issues.

Are pregnancy and neonatal outcomes following letrozole use comparable with natural and HRT cycles in patients undergoing single frozen-thawed embryo transfer (FET)? Letrozole use was significantly associated with higher rates of clinical pregnancy, clinical pregnancy with fetal heart beat and live birth, and with a lower rate of miscarriage, compared with natural and HRT cycles. Letrozole is the most commonly used aromatase inhibitor for mild ovarian stimulation in ART. However, the effect of letrozole on pregnancy and neonatal outcomes in FET are not well known. A retrospective cohort study was conducted using data from the Japanese national ART registry between 2012 and 2013. A total of 110 722 single FET cycles with letrozole (n = 2409), natural (n = 41 470) or HRT cycles (n = 66 843) were included. The main outcomes were the rates of clinical pregnancy, clinical pregnancy with fetal heart beat, miscarriage and live birth. Adjusted odds ratios and relative risks (RRs) were calculated using a generalized estimating equation adjusting for correlations within clinics. The rates of clinical pregnancy, clinical pregnancy with fetal heart beat, and live birth were significantly higher, while the rate of miscarriage was significantly lower in the letrozole group compared with the natural and HRT groups. In blastocyst stage transfers, the adjusted RRs for clinical pregnancy with fetal heart beat of letrozole compared with natural and HRT cycles were 1.48 (95% CI: 1.41-1.55) and 1.62 (95% CI: 1.54-1.70), respectively. Similarly, the adjusted RRs of letrozole for miscarriage compared with natural and HRT cycles were 0.91 (95% CI: 0.88-0.93) and 0.84 (95% CI: 0.82-0.87), respectively. Neonatal outcomes were mostly similar in letrozole, natural and HRT cycles. Important limitations of this study included the lack of information concerning the reasons for selecting the specific FET method, parity, the number of previous ART failures, embryo quality and the dose and duration

Women with hyperglycaemia detected during pregnancy are at greater risk for adverse pregnancy outcomes. Data on hyperglycaemia in pregnancy in sub-Saharan Africa is scanty and varied depending on the populations studied and the methodologies used to define hyperglycaemia in pregnancy. With the recent 2013 World Health Organisation (WHO) diagnostic criteria and classification, there is yet no sufficient data on the prevalence of hyperglycaemia in sub-Saharan Africa. The objective was to determine the prevalence of Hyperglycaemia first detected during pregnancy and subsequent obstetric outcomes among patients attending antenatal care (ANC) at St. Francis Hospital Nsambya. A prospective cohort study. All women with no history of diabetes mellitus attending at or after 24 weeks gestation were eligible to participate in the study. Participants underwent a standard 75 g oral glucose tolerance test (OGTT) after an informed written consent. The primary outcome was diagnosis of hyperglycaemia. Enrolled participants were followed up to delivery to assess obstetric outcomes (secondary outcomes were birth weight, neonatal admission, maternal genital trauma, delivery mode, neonatal and maternal status at discharge). 251 women were screened between December 2013 and February 2014. The prevalence of hyperglycaemia first detected in pregnancy was 31.9%. We found 23.8 % of women with hyperglycaemia had no known risk factor. Macrosomia was the only obstetric outcome that was significantly associated with hyperglycaemia. The prevalence of hyperglycaemia first detected in pregnancy was high in the studied population. Clinicians, therefore, should become more vigilant to screen for the condition. Selective screening may miss 23.8% of pregnant women with hyperglycaemia. However the cost/benefit implications of screening strategy and the recent 2013 WHO diagnostic criteria need to be studied in our setting.

To identify risk factors for suboptimal IVF outcomes using insemination with donor spermatozoa and to define a lower threshold that may signal a conversion to fertilization by ICSI rather than insemination. Retrospective, age-matched, case-control study of women undergoing non-donor oocyte IVF cycles using either freshly ejaculated (N=138) or cryopreserved donor spermatozoa (N=69). Associations between method of fertilization, semen sample parameters, and pregnancy rates were analyzed. In vitro fertilization of oocytes with donor spermatozoa by insemination results in equivalent fertilization and pregnancy rates compared to those of freshly ejaculated spermatozoa from men with normal semen analyses when the post-processing motility is greater than or equal to 88%. IVF by insemination with donor spermatozoa when the post-processing motility is less than 88% is associated with a 5-fold reduction in pregnancy rates when compared to those of donor spermatozoa above this motility threshold. When the post-processing donor spermatozoa motility is low, fertilization by ICSI is associated with significantly higher pregnancy rates compared to those of insemination. While ICSI does not need to be categorically instituted when using donor spermatozoa in IVF, patients should be counseled that conversion from insemination to ICSI may be recommended based on low post-processing motility.

To investigate the associations among underweight body mass index (BMI), pregnancy, and obstetric outcomes among women using assisted reproductive technology (ART). Retrospective cohort study using national data and log binomial regression. Not applicable. Women undergoing IVF in the United States from 2008 to 2013. None. Pregnancy outcomes (intrauterine pregnancy, live birth rates) per transfer, miscarriage rate per pregnancy, and low birth weight and preterm delivery rates among singleton and twin pregnancies. For all fresh autologous in vitro fertilization (IVF) cycles in the United States from 2008 to 2013 (n = 494,097 cycles, n = 402,742 transfers, n = 180,855 pregnancies) reported to the national ART Surveillance System, compared with normal weight women, underweight women had a statistically significant decreased chance of intrauterine pregnancy (adjusted risk ratio [aRR] 0.97; 95% confidence interval [CI], 0.96-0.99) and live birth (aRR 0.95; 95% CI, 0.93-0.98) per transfer. Obese women also had a statistically decreased likelihood of both (aRR 0.94; 95% CI, 0.94-0.95; aRR 0.87; 95% CI, 0.86-0.88, respectively). Among cycles resulting in singleton pregnancy, both underweight and obese statuses were associated with increased risk of low birth weight (aRR 1.39; 95% CI, 1.25-1.54, aRR 1.26; 95% CI, 1.20-1.33, respectively) and preterm delivery (aRR 1.12; 95% CI, 1.01-1.23, aRR 1.42; 95% CI, 1.36-1.48, respectively). The association between underweight status and miscarriage was not statistically significant (aRR 1.04; 95% CI, 0.98-1.11). In contrast, obesity was associated with a statistically significantly increased miscarriage risk (aRR 1.23; 95% CI, 1.20-1.26). Among women undergoing IVF, prepregnancy BMI affects pregnancy and obstetric outcomes. Underweight status may have a limited impact on pregnancy and live-birth rates, but it is associated with increased preterm and low-birth-weight delivery risk. Obesity negatively impacts all ART and obstetric

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

This systematic review investigates associations between maternal pre-pregnancy/early-pregnancy anthropometrics (e.g. weight and body fat), anthropometric change and pregnancy outcomes in South Asian and White women. Twelve electronic literature databases, reference lists and citations of all included studies were searched. Observational studies published in the English language were included. Descriptive synthesis was used to summarize the evidence base. Twenty-two studies met the inclusion criteria (403,609 births [351,856 White and 51,753 South Asian]). Nine were prospective cohort studies, nine were retrospective cohort studies and two were cross-sectional studies. Results suggested that in South Asian women, maternal pre-pregnancy/early-pregnancy anthropometrics were associated with anthropometric change, birthweight, mode of delivery and gestational diabetes mellitus (GDM). Gestational anthropometric change was found to be associated with GDM. There was limited evidence to suggest that there may be associations between maternal pre-anthropometrics/early anthropometrics and hypertensive disorders, stillbirth, congenital anomalies, post-natal weight retention and post-natal impaired glucose tolerance. The evidence suggested a combined effect of pre-pregnancy/early-pregnancy anthropometrics and gestational anthropometric change on both GDM and post-natal weight retention. The increased risk of adverse pregnancy outcomes in South Asian women should be considered in guidelines for weight management before and during pregnancy. © 2018 The Authors.

The root extract of Salacia reticulata Wight (family: Celastraceae) is used in Sri Lanka by traditional practitioners as a herbal therapy for glycemic control even during pregnancy. It is recognized that some clinically used antidiabetic drugs have harmful effects on pregnancy but the effects of the S. reticulata root extract on reproductive outcome is unknown and deserves examination. We determined the effects of the S. reticulata root extract on the reproductive outcome of Wistar rats (250-260 g) when administered orally (10 g/kg) during early (days 1-7) and mid- (days 7-14) pregnancy. The root extract significantly (P<0.05) enhanced post-implantation losses (control vs treatment: early pregnancy, 4.7 2.4 vs 49.3 13%; mid-pregnancy, 4.7 2.4 vs 41.7 16.1%). Gestational length was unaltered but the pups born had a low birth weight (P<0.05) (early pregnancy, 6.8 0.1 vs 5.3 0.1 g; mid-pregnancy, 6.8 0.1 vs 5.0 0.1 g) and low birth index (P<0.05) (early pregnancy, 95.2 2.4 vs 50.7 12.9%; mid-pregnancy, 95.2 2.4 vs 58.3 16.1%), fetal survival ratio (P<0.05) (early pregnancy, 95.2 2.4 vs 50.7 12.9; mid-pregnancy, 95.2 2.4 vs 58.3 16.1), and viability index (P<0.05) (early pregnancy, 94.9 2.6 vs 49.5 12.5%; mid-pregnancy, 94.9 2.6 vs 57.1 16.1%). However, the root extract was non-teratogenic. We conclude that the S. reticulata root extract can be hazardous to successful pregnancy in women and should not be used in pregnancy complicated by diabetes.

Background While community health workers are being recognized as an integral work force with growing responsibilities, increased demands can potentially affect motivation and performance. The ubiquity of mobile phones, even in hard-to-reach communities, has facilitated the pursuit of novel approaches to support community health workers beyond traditional modes of supervision, job aids, in-service training, and material compensation. We tested whether supportive short message services (SMS) could improve reporting of pregnancies and pregnancy outcomes among community health workers (Health Surveillance Assistants, or HSAs) in Malawi. Methods and Findings We designed a set of one-way SMS that were sent to HSAs on a regular basis during a 12-month period. We tested the effectiveness of the cluster-randomized intervention in improving the complete documentation of a pregnancy. We defined complete documentation as a pregnancy for which a specific outcome was recorded. HSAs in the treatment group received motivational and data quality SMS. HSAs in the control group received only motivational SMS. During baseline and intervention periods, we matched reported pregnancies to reported outcomes to determine if reporting of matched pregnancies differed between groups and by period. The trial is registered as ISCTRN24785657. Conclusions Study results show that the mHealth intervention improved the documentation of matched pregnancies in both the treatment (OR 1.31, 95% CI: 1.10–1.55, p<0.01) and control (OR 1.46, 95% CI: 1.11–1.91, p = 0.01) groups relative to the baseline period, despite differences in SMS content between groups. The results should be interpreted with caution given that the study was underpowered. We did not find a statistically significant difference in matched pregnancy documentation between groups during the intervention period (OR 0.94, 95% CI: 0.63–1.38, p = 0.74). mHealth applications have the potential to improve the tracking and data quality of

The objective of this study was to investigate the associations among the mid-pregnancy glycated hemoglobin A1c (HbA1c) level, gestational diabetes (GDM), and risk of adverse pregnancy outcomes in women without overt diabetes and with positive 50-g, 1-h glucose challenge test (GCT) results (140 mg/dL or greater). This prospective study enrolled 1,989 pregnant Taiwanese women. A two-step approach, including a 50-g, 1-h GCT and 100-g, 3-h oral glucose tolerance test (OGTT), was employed for the diagnosis of GDM at weeks 23-32. The mid-pregnancy HbA1c level was measured at the time the OGTT was performed. A receiver operating characteristic (ROC) curve was used to determine the relationship between the mid-pregnancy HbA1c level and GDM. Multiple logistic regression models were implemented to assess the relationships between the mid-pregnancy HbA1c level and adverse pregnancy outcomes. An ROC curve demonstrated that the optimal mid-pregnancy HbA1c cut-off point to predict GDM, as diagnosed by the Carpenter-Coustan criteria using a two-step approach, was 5.7%. The area under the ROC curve of the mid-pregnancy HbA1c level for GDM was 0.70. Compared with the levels of 4.5-4.9%, higher mid-pregnancy HbA1c levels (5.0-5.4, 5.5-5.9, 6.0-6.4, 6.5-6.9, and >7.0%) were significantly associated with increased risks of gestational hypertension or preeclampsia, preterm delivery, admission to the neonatal intensive care unit, low birth weight, and macrosomia (the odds ratio [OR] ranges were 1.20-9.98, 1.31-5.16, 0.88-3.15, 0.89-4.10, and 2.22-27.86, respectively). The mid-pregnancy HbA1c level was associated with various adverse pregnancy outcomes in high-risk Taiwanese women. However, it lacked adequate sensitivity and specificity to replace the two-step approach in the diagnosis of GDM. The current study comprised a single-center prospective study; thus, additional, randomized control design studies are required.

Background and Objectives: There is conflicting data on the effect of HIV infection as well as antiretroviral therapy (ART) on pregnancy outcome. The objectives of this study were to compare pregnancy outcomes in women with and without HIV infection, and to evaluate the effect of HAART on pregnancy in HIV-infected women. Methods: This is a prospective case record analysis of 212 HIV-infected women delivering between 2002 and 2015, in a tertiary health care center in India. The pregnancy outcome in HIV-infected women was compared to 238 HIV-uninfected controls. Women received ART for prevention of mother to child transmission as per protocol which varied during the period of study. Effect of use of ART on preterm birth (PTB) and intrauterine growth restriction (IUGR) was analyzed. Results: HIV-infected women were more likely to have PTB, IUGR, and anemia (9.4%, 9.9%, 5.2%) compared to uninfected women (7.6%, 5%, 3.8%), this did not reach statistical significance (P-value = >0.05). The incidence of PIH, diabetes mellitus and intrahepatic cholestasis of pregnancy was similar in both groups. Mean birth weight was significantly lower in neonates of HIV-infected women (2593.60±499g) than HIV-uninfected women (2919±459g) [P-value=0.001]. neonatal intensive care unit admissions were also significantly higher in infants born to HIV-infected women (P-value=0.002). HIV-infected women on ART had decreased incidence of PTB and IUGR. Conclusion and Global Health Implications: Good antenatal care and multidisciplinary team approach can optimize pregnancy outcomes in HIV-infected women. PMID:28798896

Subclinical hypothyroidism (SCH) has been associated with increased risk of adverse pregnancy outcomes in some, but not all, studies. Uncertainty remains regarding the impact of levothyroxine (LT4) therapy on improving health outcomes in pregnant women with SCH. The objective of this study was to assess the potential benefits of LT4 therapy in pregnant women with SCH. The medical records were reviewed of pregnant women with SCH, defined as an elevated serum thyrotropin (TSH) of >2.5 mIU/L for the 1st trimester or >3 mIU/L for the 2nd and 3rd trimesters, but ≤10 mIU/L. Pregnant women were divided into two groups depending on whether they received LT4 (group A) or not (group B). Pregnancy loss and other pre-specified adverse outcomes were evaluated during follow-up. There were 82 women in group A and 284 in group B. Group A had a higher body mass index (p = 0.04) and a higher serum TSH level (p < 0.0001) compared with group B. Group A had fewer pregnancies lost (n = 5 [6.1%] vs. n = 25 [8.8%]; p = 0.12), low birth weight (LBW) offspring (1.3% vs. 10%; p < 0.001), and no neonates with a five-minute Apgar score ≤7 (0% vs. 7%; p < 0.001) compared with group B. Other pregnancy-related adverse outcomes were similar between the two groups. Inferences remained unchanged after considering different models to adjust for potential predictors of outcome. LT4 therapy is associated with a decreased risk of LBW and a low Apgar score among women with SCH. This association awaits confirmation in randomized trials before the widespread use of LT4 therapy in pregnant women with SCH.

Background Advanced maternal age (AMA; ≥35 years) is an increasing trend and is reported to be associated with various pregnancy complications. Objective To determine the risk of stillbirth and other adverse pregnancy outcomes in women of AMA. Search strategy Embase, Medline (Ovid), Cochrane Database of Systematic Reviews, ClinicalTrials.gov, LILACS and conference proceedings were searched from ≥2000. Selection criteria Cohort and case-control studies reporting data on one or more co-primary outcomes (stillbirth or fetal growth restriction (FGR)) and/or secondary outcomes in mothers ≥35 years and <35 years. Data collection and analysis The effect of age on pregnancy outcome was investigated by random effects meta-analysis and meta-regression. Stillbirth rates were correlated to rates of maternal diabetes, obesity, hypertension and use of assisted reproductive therapies (ART). Main results Out of 1940 identified titles; 63 cohort studies and 12 case-control studies were included in the meta-analysis. AMA increased the risk of stillbirth (OR 1.75, 95%CI 1.62 to 1.89) with a population attributable risk of 4.7%. Similar trends were seen for risks of FGR, neonatal death, NICU unit admission restriction and GDM. The relationship between AMA and stillbirth was not related to maternal morbidity or ART. Conclusions Stillbirth risk increases with increasing maternal age. This is not wholly explained by maternal co-morbidities and use of ART. We propose that placental dysfunction may mediate adverse pregnancy outcome in AMA. Further prospective studies are needed to directly test this hypothesis. PMID:29040334

Hyperthyroidism has important implications for pregnancy, affecting both mother and fetus. Appropriate maternal and fetal management iscritical to avoiding adverse pregnancy outcomes and requires a multidisciplinary approach. To describe maternal diagnosis and management of hyperthyroidism, across all stages of pregnancy. In addition, to review clinical signs of fetal thyroid dysfunction due to maternal Graves disease and discuss management considerations. Review of published articles on PubMed and guidelines by recognized governing organizations regarding the diagnostic and management considerations for hyperthyroidism in pregnancy, from preconception to the postpartum period. Diagnosis of maternal hyperthyroidism involves both clinical symptoms and laboratory findings. Antithyroid medications are the mainstay of therapy, with trimester-specific pregnancy goals. Hyperthyroidism due to Graves disease has important diagnostic and management considerations for the fetus and neonate. Hyperthyroidism in pregnancy affects mother, fetus, and neonate. Interpretation of thyroid tests and understanding the appropriate use of antithyroid drugs are fundamental. Proper education of physicians providing care to women with hyperthyroidism is essential and starts before pregnancy. Postpartum follow-up is an essential part of the care. A systematic approach to management will ensure optimal pregnancy outcomes.

To analyze the various factors in an in vitro fertilization and embryo transfer (IVF-ET) program which may affect the clinical pregnacy rate. A retrospective study was done on 559 IVF-ET cycles from 1992-Nov. 1995. The indication for treatment was bilateral tubal blockage. The chi 2 analysis of single factor variants with SPSS-PC + V3.0 was used for statistics. The overall clinical pregnancy rate in 559 cycles was 21.6%. The cause of tubal blockage due to tuberculoses consisted of 28.4%, and 34.9% of secondary sterility had the history of artificial abortion. The changes of environment, the different causes of tubal blockage, the history of previous intrauterine pregnancy did not affect the clinical pregnancy rate. When the number of embryos transferred increased to 5, the clinical pregnancy rate was highest 32.5%. The cumulative embryo score or embryo quality was related significantly with clinical pregnancy rate. The number and quality of embryos transferred are important factors affecting the clinical pregnancy rate. However, measures to prevent high-order multiple pregnancy and studies on the survival potential of embryos besides their morphology should be emphasized.

However, birth certificate data are ill equipped to reliably differentiate among small for gestational age, spontaneous preterm birth, and medically indicated preterm birth. We sought to utilize data from electronic medical records to determine whether residential segregation among Black women is associated with an increased risk of adverse pregnancy outcomes. The study population was composed of 4770 non-Hispanic Black women who delivered during the years 2009 through 2013 at a single urban medical center. Addresses were geocoded at the level of census tract, and this tract was used to determine the degree of residential segregation for an individual's neighborhood. Residential segregation was measured using the Gi* statistic, a z-score that measures the extent to which the neighborhood racial composition deviates from the composition of the larger surrounding area. The Gi* statistic z-scores were categorized as follows: low (z < 0), medium (z = 0-1.96), and high (z > 1.96). Adverse pregnancy outcomes included overall preterm birth, spontaneous preterm birth, medically indicated preterm birth, and small for gestational age. Hierarchical logistic regression models accounting for clustering by census tract and repeated births among mothers were used to estimate odds ratios of adverse pregnancy outcomes associated with segregation. In high segregation areas, the prevalence of overall preterm birth was significantly higher than that in low segregation areas (15.5% vs 10.7%, respectively; P < .001). Likewise, the prevalence of spontaneous preterm birth and medically indicated preterm birth were higher in high (9.5% and 6.0%) vs low (6.2% and 4.6%) segregation neighborhoods (P < .001 and P = .046, respectively). The associations of high segregation with overall preterm birth (odds

The aim of the article is to determine whether prior spontaneous abortion (SAB) or induced abortion (IAB), or the interpregnancy interval are associated with subsequent adverse pregnancy outcomes in nulliparous women. We performed a secondary analysis of data collected from nulliparous women enrolled in a completed trial of vitamins C and E or placebo for preeclampsia prevention. Adjusted odds ratios (ORs) for maternal and fetal outcomes were determined for nulliparous women with prior SABs and IABs as compared with primigravid participants. Compared with primigravidas, women with one prior SAB were at increased risk for perinatal death (adj. OR, 1.5; 95% CI, 1.1-2.3) in subsequent pregnancies. Two or more SABs were associated with an increased risk for spontaneous preterm birth (PTB) (adj. OR, 2.6, 95% CI, 1.7-4.0), preterm premature rupture of membranes (PROM) (adj. OR, 2.9; 95% CI, 1.6-5.3), and perinatal death (adj. OR, 2.8; 95% CI, 1.5-5.3). Women with one previous IAB had higher rates of spontaneous PTB (adj. OR, 1.4; 95% CI, 1.0-1.9) and preterm PROM (OR, 2.0; 95% CI, 1.4-3.0). An interpregnancy interval less than 6 months after SAB was not associated with adverse outcomes. Nulliparous women with a history of SAB or IAB, especially multiple SABs, are at increased risk for adverse pregnancy outcomes. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

Pregnancy in the setting of the uremic milieu of renal disease has a lower success rate than in the normal population and is a rare event. While intensified renal replacement therapy (RRT) during pregnancy can lead to improved outcomes, most studies have focused on nocturnal hemodialysis as the main RRT in pregnancy. Although thousands of patients use the home NxStage System One short daily hemodialysis (SDHD) machine in the United States, pregnancy outcomes with this therapy are unknown. The NxStage System One uses low-volume dialysate and hence small and middle molecule clearance may differ compared to conventional therapies and affect pregnancy outcomes. We report a case of a successful conception and pregnancy using the home NxStage system. The NxStage system may provide an alternative to the more routinely used NHD or standard SDHD therapies for women of childbearing age. PMID:26949554

Pregnancy is a complex period of human growth, development, and imprinting. Nutrition and metabolism play a crucial role for the health and well-being of both mother and fetus, as well as for the long-term health of the offspring. Nevertheless, several biological and physiological mechanisms related to nutritive requirements together with their transfer and utilization across the placenta are still poorly understood. In February 2009, the Child Health Foundation invited leading experts of this field to a workshop to critically review and discuss current knowledge, with the aim to highlight priorities for future research. This paper summarizes our main conclusions with regards to maternal preconceptional body mass index, gestational weight gain, placental and fetal requirements in relation to adverse pregnancy and long-term outcomes of the fetus (nutritional programming). We conclude that there is an urgent need to develop further human investigations aimed at better understanding of the basis of biochemical mechanisms and pathophysiological events related to maternal-fetal nutrition and offspring health. An improved knowledge would help to optimize nutritional recommendations for pregnancy.

Recent research emphasized the nutritional benefits of omega-3 long chain polyunsaturated fatty acids (LCPUFAs) during pregnancy. Based on a double-blind randomised controlled trial named "DHA to Optimize Mother and Infant Outcome" (DOMInO), we examined how omega 3 DHA supplementation during pregnancy may affect pregnancy related in-patient hospital costs. We conducted an econometric analysis based on ordinary least square and quantile regressions with bootstrapped standard errors. Using these approaches, we also examined whether smoking, drinking, maternal age and BMI could influence the effect of DHA supplementation during pregnancy on hospital costs. Our regressions showed that in-patient hospital costs could decrease by AUD92 (P<0.05) on average per singleton pregnancy when DHA supplements were consumed during pregnancy. Our regression results also showed that the cost savings to the Australian public hospital system could be between AUD15 - AUD51 million / year. Given that a simple intervention like DHA-rich fish-oil supplementation could generate savings to the public, it may be worthwhile from a policy perspective to encourage DHA supplementation among pregnant women.

Nuchal Translucency (NT) is the sonographic form of subcutaneous gathering of liquid behind the foetal neck in the first trimester of pregnancy. There is association of increased NT with chromosomal and non-chromosomal abnormalities. The purpose of this systemic review was to review the pregnancy outcome of abnormal nuchal translucency. The present systematic review was conducted by searching English language articles from sources such as International Medical Sciences, Medline, Web of science, Scopus, Google Scholar, PubMed, Index Copernicus, DOAJ, EBSCO-CINAHL. Persian articles were searched from Iranmedex and SID sources. Related key words were "outcome", "pregnancy", "abnormal", and "Nuchal Translucency" (NT). All, randomized, descriptive, analytic-descriptive, case control study conducted during 1997-2015 were included. Including duplicate articles, 95 related articles were found. After reviewing article titles, 30 unrelated article and abstracts were removed, and 65 articles were evaluated of which 30 articles were duplicate. Finally 22 articles were selected for final analysis. Exclusion criteria were, case studies and reports and quasi experimental designs. This evaluation has optioned negative relationship between nuchal translucency and pregnancy result. Rate of cardiac, chromosomal and other defects are correlated with increased NT≥2.5mm. Cardiac disease which were associated to the increased NT are heart murmur, systolic organic murmur, Atrial Septal Defect (ASD), Ventricular Septal Defect (VSD), tricuspid valve insufficiency and pulmonary valve insufficiency, Inferior Vena Cava (IVC) and Patent Ductus Arteriosus (PDA). The most common problems that related with increased NT were allergic symptoms. According to this systematic review, increased NT is associated with various foetal defects. To verify the presence of malformations, birth defect consultations with a perinatologist and additional tests are required.

The purpose of this study is to determine the adverse perinatal outcomes in uncomplicated late preterm pregnancies with borderline oligohydramnios. A total of 430 pregnant women with an uncomplicated singleton pregnancy at a gestational age of 34 + 0-36 + 6 weeks were included. Borderline oligohydramnios was defined as an amniotic fluid index (AFI) of 5.1-8 cm, which was measured using the four-quadrant technique. Adverse perinatal outcomes were compared between the borderline and normal AFI groups. Approximately 107 of the 430 pregnant women were borderline AFI, and 323 were normal AFI. The demographic and obstetric characteristics were similar in both groups. Delivery <37 weeks, cesarean delivery for non-reassuring fetal heart-rate testing, meconium-stained amniotic fluid, Apgar 5 min <7, transient tachypnea of the newborn, respiratory distress syndrome, neonatal intensive care unit, and hyperbilirubinemia were not statistically different between the groups (p = .054, p = .134, p = .749, p = 0.858, p = .703, p = .320, p = .185, and p = .996, respectively). Although gestational age was full-term, induction of labor rates were significantly higher in the borderline AFI group (p = .040). In addition, fetal renal artery pulsatility index pulsatility index (PI) was significantly lower in the borderline AFI group than in the normal AFI group (p = .014). Our results indicated that borderline AFI was not a risk for adverse perinatal outcomes in uncomplicated, late preterm pregnancies.

There is an increasing prevalence of women with congenital heart defects reaching childbearing age. In western countries women tend to give birth at a higher age compared to some decades ago. We evaluated the CARdiac disease in PREGnancy (CARPREG) and modified World Health Organization (mWHO) risk classifications for cardiac complications during pregnancies in women with congenital heart defects and analyzed the impact of age on risk of obstetric and fetal outcome. A single-center observational study of cardiac, obstetric, and neonatal complications with data from cardiac and obstetric records of pregnancies in women with congenital heart disease. Outcomes of 496 pregnancies in 232 women, including induced abortion, miscarriage, stillbirth, and live birth were analyzed regarding complications, maternal age, mode of delivery, and two risk classifications: CARPREG and mWHO. There were 28 induced abortions, 59 fetal loss, 409 deliveries with 412 neonates. Cardiac (14%), obstetric (14%), and neonatal (15%) complications were noted, including one maternal death and five stillbirths. The rate of cesarean section was 19%. Age above 35years was of borderline importance for cardiac complications (p=0.054) and was not a significant additional risk factor for obstetric or neonatal complications. Both risk classifications had moderate clinical utility, with area under the curve (AUC) 0.71 for CARPREG and 0.65 for mWHO on cardiac complications. Pregnancy complications in women with congenital heart disease are common but severe complications are rare. Advanced maternal age does not seem to affect complication rate. Existing risk classification systems are insufficient in predicting complications. Copyright © 2017 Elsevier B.V. All rights reserved.

This study investigates the effects of anticoagulant therapy on pregnancy outcomes in 204 patients with thrombophilia and previous poor obstetric outcomes. Patients with poor obstetric history (pre-eclampsia, intrauterine growth retardation, fetal death, placental abruption, recurrent pregnancy loss) and having hereditary thrombophilia were included in this study. Poor obstetric outcomes were observed more frequently in patients who had not taken anticogulant therapy compared with treated group. Live birth rate, gestational age at birth and Apgar scores were significantly higher in the treated group when compared with the untreated group. There were no significant differences in terms of birthweight, mode of delivery and admission rates to the neonatal intensive care unit (NICU). Low-molecular-weight heparin (LMWH) plus acetylsalicylic acid (ASA) had higher gestational age at birth, Apgar scores, live birth rate and a lower abortion rates when compared with controls; in contrast, no significant difference was observed in terms of birthweight, mode of delivery, obstetric complications and admission rates to NICU. There were no significant differences between control group and both LMWH only and ASA only groups in terms of gestational age at birth, Apgar scores, birthweight, mode of delivery, obstetric complications and admission rates to NICU. Only LMWH group had higher live birth rate as compared with control group. The use of only ASA did not seem to affect the perinatal complication rates and outcomes. In conclusion, anticoagulant therapy with both LMWH and ASA seems to provide better obstetric outcomes in pregnant women with thrombophilia and previous poor obstetric outcomes.
