Maternal and neonatal outcomes in triplet gestations by trial of labor versus planned cesarean delivery*

Objective: To determine the rate of vaginal delivery after vaginal trial of labor (TOL) among women with triplet gestations.

Study design: This is a retrospective cohort study of all women delivering a viable triplet gestation between 2005 and 2016. The primary outcome was rate of vaginal delivery among all women attempting vaginal delivery. Secondary outcomes included factors associated with undergoing triplet TOL, and maternal and neonatal complications by planned delivery approach.

Results: Of the 83 eligible women, 21 (25.3%) underwent TOL. A majority of these (57.1, 95% confidence interval 36.5–75.5%) achieved a vaginal delivery of all three triplets. Women who underwent TOL were more likely to be multiparous or to have spontaneous preterm labor. There were no differences in adverse maternal or neonatal outcomes by planned delivery approach.

Conclusions: The rate of vaginal delivery among women with triplet gestations is higher in this institution than in reported literature, without increased morbidity.     

Maternal and neonatal hyponatremia during labor: a case series

Background: Hyponatremia during labor and delivery may result in severe maternal and neonatal sequelae. Our aim was to describe the direct effect of hyponatremia in labor on pregnancy outcome.

Methods: A case series of parturients diagnosed with hyponatremia during labor and their neonates. Clinical presentation, laboratory workup, and maternal and neonatal outcomes are presented.

Results: Four parturients and their corresponding six neonates were diagnosed with hyponatremia. Of these, two cases were caused by water intoxication and two were preeclampsia induced. While two were identified due to maternal or neonatal symptoms, two were diagnosed by routine laboratory testing. In all cases, low maternal sodium resulted in similarly low neonatal sodium. Neonatal symptoms included respiratory distress syndrome (RDS), lethargy, and jaundice.

Conclusion: Psychogenic drinking during labor and preeclampsia may predispose to maternal hyponatremia, resulting in neonatal hyponatremia. Early recognition and treatment can prevent further maternal deterioration and adverse neonatal sequelae.     

Neonatal intensive care unit admission and maternal postpartum depression

Objective: This study aimed to examine the impact of newborns’ Neonatal Intensive Care Unit (NICU) admittance on maternal postpartum depression.

Background: Prior research on the parental psychological impacts of a NICU admittance typically includes a hospital sample of parents following birth, so the causality of NICU admittance and maternal depressive symptomatology is unclear.

Methods: 127 women across 38 counties in a South Central US state participated in online surveys in their third trimester and approximately six weeks post-birth in 2016. Pre- and post-birth assessments of depression were measured with the Center for Epidemiologic Studies Depression Scale (CES-D). NICU admittance was asked in the post-birth survey. t-Tests and multivariable regression analyses were used to determine predictors of NICU admittance and postnatal depressive symptomatology.

Results: Findings indicate that prenatal depression does not differ significantly between mothers by NICU admission status, but NICU admission is a significant predictor of postpartum depressive symptomatology.

Conclusions: Having a newborn admitted to the NICU is a risk factor for maternal postpartum depression. These findings have implications for practice; screening mothers in the NICU for depression as a target for intervention has the potential to improve maternal well-being, which in turn should enhance subsequent infant developmental outcomes.     

Strategies for the prediction of late preeclampsia

Objectives: To evaluate different strategies for the prediction of late preeclampsia.

Methods: A retrospective study was undertaken. A predictive model including maternal parameters (maternal age, maternal BMI, maternal history of preeclampsia or intrauterine growth restriction (PE/IUGR) or maternal chronic disease, and maternal arterial pressure) and mean pulsatility index (PI) of uterine Doppler was created. It was evaluated as an independent model in each trimester, considering 11–13.6 weeks, 20–22.6 weeks and 32–33.6 weeks consequently, and as an integrated model.

Results: In the group of late preeclampsia, patients were more obese and had higher incidence of chronic hypertension. Uterine artery pulsatility index (UtA PI) and mean blood pressure were increased in all three trimesters. When evaluating all three models independently, third trimester model performed better than the other two with a sensitivity of 79% and specificity of 82%. The area under the receiver-operating characteristic (ROC) curve (AUC) was 0.86. The integration of all three determinations did not improve third trimester’s model.

Conclusion: Prediction of late preeclampsia at third trimester seems to be possible if maternal characteristics, blood pressure and UtA Doppler are included.     

Neuropathological complications associated with hypertensive disorders of pregnancy

Objective: Hypertensive disorders in pregnancy particularly severe preeclampsia and eclampsia result in significant maternal and neonatal morbidity and mortality. Many of these misfunctions can aggravate some of the neuropathological complications of hypertensive disorders during pregnancy.

Method: In this review article, we described some of the neuropathological complications associated with hypertensive disorders of pregnancy.

Results and conclusion: It is explained how the possible mechanism of neuropathological events triggers some of the complications associated with hypertensive disorders of pregnancy.

Conclusion: A strong plea is made for the early detection of high blood pressure, its immediate control with rapid acting anti-hypertensive agents if necessary and timeous delivery of fetus as the exact pathogenesis of preeclampsia remains unknown.     

Evaluation of late adolescent pregnancies: Is late adolescence a risk factor for preterm labor?

Study objective: We evaluated effect of late adolescence during pregnancy and its confounding factors on neonatal and maternal results.

Objective: The aim of the present study is to evaluate the effect of late adolescence on maternal, perinatal outcomes and preterm labor.

Methods: This retrospective study was carried out on 172 late adolescents and 160 adult women who delivered in a tertiary center. The demographic features, obstetrical and neonatal properties of the patients were analyzed.

Results: Marital status, education levels, preeclampsia–eclampsia, gestational diabetes mellitus (GDM), urinary tract infections during pregnancy, intrauterine growth restriction, bleeding in last trimester, postpartum hemorrhage, perinatal mortality incidence, and mode of delivery for both groups were similar. Regular antenatal follow up and hemoglobin levels during admission to hospital were low in late adolescents. Anemia during pregnancy, preterm labor incidence was high for late adolescents compared with adults. When a logistic regression analysis was made for preterm labor, lack of antenatal follow up, urinary tract infection during pregnancy and history of still birth was risk factors for preterm labor rather than age.

Conclusion: We assume that regular antenatal follow up can reduce preterm labor among late adolescents.     

Amniocentesis compared with antenatal corticosteroids prior to early term scheduled cesarean delivery

Objective: There are a variety of maternal or fetal conditions that require late preterm or early term delivery. In cases where early delivery is indicated, optimal management is not always clear. Historically, obstetricians used amniocentesis to document fetal lung maturity, but recently, many have transitioned to administration of antenatal corticosteroids (ACS). The objective of this study was to compare neonatal outcomes between women undergoing amniocentesis or receiving ACS prior to scheduled cesarean delivery (CD) less than 39 weeks.

Methods: This was a retrospective cohort study of women undergoing scheduled CD by one maternal-fetal medicine practice between 36 and 38 6/7 weeks, from 2005 to 2017. We identified women who underwent amniocentesis or received ACS within 2 weeks prior to delivery. Neonatal outcomes were compared between the two groups, with the primary outcome being neonatal intensive care unit (NICU) admission.

Results: A total of 502 women were included, of whom 313 (62.4%) underwent amniocentesis and 189 (37.6%) received ACS. Overall, 55 (11.0%) of neonates were admitted to the NICU. NICU admission was not significantly different between groups (11.8 versus 9.5%, p=.46). This held true after adjusting for gestational age and other differences in baseline characteristics. There were no significant differences between groups for all other neonatal outcomes, including NICU admission for respiratory indications, respiratory support, neonatal greater than maternal length of stay, low Apgar scores, and neonatal death. Rates of hypoglycemia were low and not significantly different between groups (2.2% in the amniocentesis group versus 0.5% in the ACS group, p=.27). Diabetes was the only covariate significantly associated with NICU admission (aOR 3.19, 95% CI 1.35, 7.54).

Conclusions: In women undergoing scheduled CD between 36 and 38 6/7 weeks, administration of ACS is associated with similar neonatal outcomes compared to amniocentesis. This supports the current notion that outcomes are similar with ACS compared to amniocentesis for late preterm and early term deliveries.

Brief rationale: The objective of this study was to compare neonatal outcomes between women undergoing amniocentesis or receiving antenatal corticosteroids (ACS) prior to scheduled cesarean delivery (CD) less than 39 weeks. We found that in women undergoing scheduled cesarean delivery between 36 and 38 6/7 weeks, administration of antenatal corticosteroids is associated with similar neonatal outcomes compared to amniocentesis.     

The importance of proteinuria in preeclampsia and its predictive role in maternal and neonatal outcomes

Objective: To evaluate impact of 24-h proteinuria level in preeclampsia on maternal/perinatal outcomes.

Methods: Singleton pregnancies with preeclampsia delivered after 24 weeks of gestation were included. Patients were divided into mild (0.3 to <2 g) (n=72), severe (2 to <5 g) (n=30), and massive (≥5 g) (n=24) proteinuria groups, and cut-off values of 24-h proteinuria for composite adverse maternal and neonatal outcomes were calculated.

Results: Twenty-four hour proteinuria level cut-offs for composite adverse outcomes were 3275 mg (72.2% sensitivity, 85.6% specificity) and 2395 mg (72.7% sensitivity, 78% specificity) respectively.

Conclusion: Severe and massive proteinuria were related to poor maternal, perinatal, and neonatal outcomes.     

Stress and anxiety among mothers of premature infants in a Malaysian neonatal intensive care unit

Objective: This study aims to determine maternal stress and anxiety as perceived by mothers whose premature infants were admitted to the neonatal intensive care unit (NICU) and to identify maternal stress and its relationship with maternal and infant characteristics and anxiety.

Background: Vulnerable premature infants commonly require special care in the NICUs. In most cases, prolonged hospitalization results in stress and anxiety for the mothers.

Methods: A non-probability convenience survey was used in a public hospital, with 180 mothers completing the 26-item Perceived Stress Scale (PSS) and a 40-item State-Trait Anxiety Inventory (STAI).

Results: 56.5% of mothers had high levels of stress, 85.5% of mothers had a high level of state-anxiety and 67.8% of mothers had a high level of trait-anxiety. The stress experienced by these mothers had a significant relationship with anxiety, and was found to be associated with state and trait anxiety levels, but not with maternal and infant characteristics.

Conclusion: Mothers in this setting revealed high levels of stress and anxiety during their premature infants’ NICU admission. An immediate interventional programme focusing on relieving mothers’ anxiety and stress is needed to prevent maternal stress and anxiety at an early stage.     

Haptotherapy as a new intervention for treating fear of childbirth: a randomized controlled trial

Objective: To evaluate the effect of haptotherapy on severe fear of childbirth in pregnant women.

Design: Randomized controlled trial.

Setting: Community midwifery practices and a teaching hospital in the Netherlands.

Population or Sample: Primi- and multigravida, suffering from severe fear of childbirth (N?=?134).

Methods: Haptotherapy, psycho-education via Internet and care as usual were randomly assigned at 20–24?weeks of gestation and the effects were compared at 36?weeks of gestation and 6?weeks and 6?months postpartum. Repeated measurements ANOVA were carried out on the basis of intention to treat. Since there were crossovers from psycho-education via Internet and care as usual to haptotherapy, the analysis was repeated according to the as treated principle.

Main outcome measures: Fear of childbirth score at the Wijma Delivery Expectancy/Experience Questionnaire.

Results: In the intention to treat analysis, only the haptotherapy group showed a significant decrease of fear of childbirth, F(2,99)?=?3.321, p?=?.040. In the as treated analysis, the haptotherapy group showed a greater reduction in fear of childbirth than the other two groups, F(3,83)?=?6.717, p?<?.001.

Conclusion: Haptotherapy appears to be more effective in reducing fear of childbirth than psycho-education via Internet and care as usual.     

Evaluation of fetal serum thiol/disulphide homeostasis in deliveries complicated by nuchal cord

Aim: To investigate the serum thiol/disulphide homeostasis in deliveries complicated by nuchal cord (NC) and to compare the results with healthy deliveries (without NC).

Methods: This prospective controlled study included 48 pregnant women complicated by NC and 48 similar gestational aged healthy pregnant women during labor. Fetal umbilical cord serum samples were collected during labor and the thiol/disulphide homeostasis was measured by using an automated assay method. The patients were followed up until end of the delivery and perinatal outcomes were recorded.

Results: Fetal umbilical cord native thiol, total thiol, and disulphide levels as well as disulphide/native thiol and disulphide/total thiol ratios are impaired in labor with the presence of NC. There were no statistically significant differences in terms of maternal and gestational age at delivery and maternal number of gravida and parity, fetal gender, fifth Apgar scores <7, mode of delivery and fetal birth weight between groups. The group of patients with NC had higher emergency C/S numbers indicated for fetal distress and lower first Apgar scores <7. There were no neonatal intensive care unit admissions among these babies.

Conclusions: Maternal serum thiol/disulphide homeostasis reflect transient effects of NC during labor regardless of labor type. Vaginal delivery can be safely and successfully performed in pregnancies complicated with NC.     

The influence of maternal life stressors on breastfeeding outcomes: a US population-based study

Objective: The purpose of this study was to examine the contribution of maternal financial, emotional, traumatic, and partner-associated stressors on breastfeeding initiation and duration.

Methods: Data (216,756 records) from the Pregnancy Risk Assessment Monitoring System surveys were used in the analysis. Logistic regressions were conducted to estimate the magnitude and direction of associations between maternal stressors occurring in the 12 months prior to infant birth and both breastfeeding initiation and duration up to 4 weeks infant age.

Results: A substantial proportion of mothers (42%) reported having experienced one or two major stressors during the 12 months prior to the birth of their infant. Mothers who reported at least one major life stressor in the year before their baby was born were less likely to initiate breastfeeding and more likely to cease by 4 weeks infant age. Emotional and traumatic stressors were found to have the greatest impact on breastfeeding outcomes.

Conclusions: Findings support the design and implementation of screening protocols for major maternal life stressors during regularly scheduled prenatal and newborn visits. Screening for at-risk mothers may lead to more targeted anticipatory guidance and referral with positive effects on breastfeeding outcomes and overall well-being of the mothers and their families.     

Postpartum maternal adipokines and infant weight for length at 1 year in women with gestational diabetes

Background: Maternal, cord blood and childhood adipokines have been associated with childhood obesity. We investigated whether postpartum maternal adipokines are associated with increased weight at 1 year of age in children of women with gestational diabetes (GDM).

Methods: Plasma leptin and adiponectin concentrations were measured in 160 women at approximately 12 weeks following pregnancy with GDM and compared with infant weight for length z-score at 1 year of age after adjustment for maternal and infant demographic variables.

Results: No association was demonstrated between maternal postpartum leptin and adiponectin concentrations and infant weight for length z-score at 1 year of age.     

Maternal periodontal disease and adverse perinatal outcomes: is there an association? A hospital-based case-control study

Objectives: The association between maternal periodontal disease and adverse perinatal outcomes although extensively studied remains unclear. The aim of this study was to evaluate, by a case-control study, conducted in three hospitals the association between preterm birth and/or low birth weight (PTB/LBW) and clinical parameters of maternal periodontal disease.

Material and methods: Postpartum women who gave birth to a newborn PTB/LBW (case group), and postpartum women who had babies at full term with normal weight (control group) were included, in 1:2 ratio. Data were collected through medical records, interview, and periodontal clinical parameters. Bivariate analysis was performed to assess the PTB/LBW proportion relative to independent variables and multiple logistic regression analysis to assess the association between adverse perinatal outcomes and independent variables.

Results: The sample consisted of 148 cases and 296 controls. By the 148 postpartum women with PTB/LBW in case group, 126 (87.5%) had preterm birth, and 75 (50.7%) had PTB and LBW. The periodontal status and generalized periodontitis presence were not associated with any adverse pregnancy outcomes. Having made four or more prenatal visits was a protective factor for all outcomes. The history of previous PTB/LBW was a risk factor for new cases of PTB and PTB and/or LBW. The presence of systemic disease was associated with preterm and low birth weight (PTLBW). Preeclampsia and cesarean delivery were associated with all outcomes.

Conclusions: The clinical parameters of maternal periodontitis were not considered as a risk factor for the studied adverse perinatal outcomes.

Clinical relevance: The present study demonstrated no association between maternal periodontitis and PTB/LBW.     

Influence of perinatal inflammation on the neurodevelopmental outcome of premature infants

Objective: To evaluate the influence of perinatal inflammation on neurodevelopmental outcome of premature infants.

Study design: From a retrospective cohort study of women with preterm labor with intact membranes or preterm prelabor rupture of membranes (PPROM) with an amniocentesis to rule out intra-amniotic inflammation (IAI) and microbial invasion of the amniotic cavity (MIAC), we evaluated neurodevelopmental outcome of their infants born between 24.0 and 34.0 weeks gestation. Women with clinical chorioamnionitis at admission were excluded. Neurodevelopmental outcome was screened with the Ages & Stages Questionnaire (ASQ)-3. We analyzed the relationship between an altered ASQ-3 and antenatal, intra-partum and post-partum factors related to perinatal inflammation.

Result: Among 98 infants evaluated, 22% had an abnormal score. Amniotic fluid interleukin-6 levels and early-onset sepsis (EOS) were independent factors of an altered ASQ-3 with delivery <26.0 weeks being the strongest predictor.

Conclusions: In premature infants, the presence of IAI, delivery <26.0 weeks and EOS were found to be independent factors of an altered ASQ-3.     

Elevated maternal serum-free β-human chorionic gonadotropin (β-hCG) and reduced risk of spontaneous preterm delivery*

Objective: To evaluate the relationship between first and second trimester maternal serum-free β-hCG and the risk of spontaneous preterm delivery (PTD).

Study design: This was a case-control study of women evaluated and delivered at our institution from 2011 to 2015. Spontaneous PTD was defined as delivery before 37 weeks due to spontaneous preterm labor or premature rupture of membranes. Patient with multifetal gestation and those with medically indicated term or PTD were excluded.

Results: Of 877 women meeting the inclusion criteria, 173 delivered preterm and 704 delivered at term, and 8.1% had high free β-hCG in one or both trimesters. High maternal first and/or second trimester free β-hCG (≥95th percentile) was associated with lower rates of PTD. Thirty-two women with high free β-hCG in both first and second trimesters delivered at term. Gestational age at delivery and birth weights were lower in women who did not have high free β-hCG in any trimester. Low free β-hCG (≤5th percentile) in either trimester was not associated with an increased or decreased likelihood of PTD. Logistic regression demonstrated an independent association of high free β-hCG (≥95th percentile) with a reduced likelihood of PTD. Stratified analysis revealed a stronger impact of this association in women with no prior history of PTD.

Conclusions: High free β-hCG, in the absence of risk factors for medically indicated PTD, is associated with a reduced likelihood of spontaneous PTD and may represent a marker indicating lower risk.     

Early unexpected diagnosis of fetal life-limiting malformation; antenatal palliative care and parental decision

Introduction: Conjoined twins are an infrequent occurrence in obstetric practice. Live-conjoined twins on a late preterm triplet pregnancy is an even rarer event.

Objective: The objective of this study is to emphasize the critical importance of perinatal palliative care and non-directive parental counseling, informed decision making and respect for autonomy following full disclosure of findings, fetal life-limiting diagnosis, treatment alternatives, maternal–fetal potential complications, and most likely perinatal outcomes.

Methods: Early surprise prenatal diagnosis, comprehensive parental counseling, palliative care, and perinatal care of a set of conjoined twins and a singleton.

Results: Cesarean delivery of a set of conjoined twins and a singleton at 34 weeks’ gestation. Immediate neonatal death of the conjoined twins, intact survival, and discharge of the singleton. Review of the database on previously reported similar cases. It is very important to utilize simple and direct language for parents to understand the grave prognosis to the pregnancy. Care alternatives in view of the maternal physical risks and psychological impact of carrying a high order abnormal multiple pregnancy, along with the possible side effects on the singleton.     

Admissions for hypoglycaemia after 35 weeks of gestation: perinatal predictors of cost of stay

Background: Hypoglycaemia accounts for approximately one-tenth of term admissions to neonatal units can cause long-term neurodevelopmental impairment and is associated with the significant burden to the affected infants, families and the health system.

Objective: To define the prevalence, length and cost of admissions for hypoglycaemia in infants born at greater than 35 weeks gestation and to identify antenatal and perinatal predictors of those outcomes.

Materials and methods: This was a retrospective audit of infants admitted for hypoglycaemia between 1 January 2012 and 31 December 2015, in a level three neonatal intensive care unit at King’s College Hospital NHS Foundation Trust, London. The main outcome measures were the prevalence, length and cost of admissions for hypoglycaemia and antenatal and postnatal predictors of the length and cost of the stay.

Results: There were 474 admissions for hypoglycaemia (17.8% of total admissions). Their median (IQR) blood glucose on admission was 2.1 (1.7–2.4) mmol/l, gestation at delivery 38.1 (36.7–39.3) weeks, birthweight percentile 31.4 (5.4–68.9), their length of stay was 3.0 (2.0–5.0). Admissions equated to a total of 2107 hospital days. The total cost of the stay was 1,316,591 Great Britain pound. The antenatal factors associated with admission for hypoglycaemia were maternal hypertension (19.8%), maternal diabetes (24.5%), foetal growth restriction (FGR) (25.9%) and pathological intrapartum cardiotocograph (23.4%). In 13.7% of cases, there was no associated pregnancy complication. Multivariate logistic regression analysis demonstrated lower gestational age, z-score birthweight squared, exclusive breastfeeding and maternal prescribed nifedipine were independently associated with the length and cost of the stay.

Conclusion: Hypoglycaemia accounted for approximately one-fifth of admissions after 35-week gestation. Lower gestational age and admission blood glucose, low and high z-score birthweight, maternal nifedipine and exclusive breastfeeding are associated with longer duration of stay.     

Recurrence of extreme serum analytes in consecutive pregnancies and association with obstetrical outcomes*

Objective: To evaluate if presence of extreme maternal serum biochemical analytes recurs in consecutive pregnancies. We hypothesized that presence of >1 extreme analyte in prior pregnancy is associated with increased risk of adverse pregnancy outcome in subsequent pregnancy.

Methods: Retrospective cohort study of singleton pregnancies evaluated and delivered in 2 consecutive pregnancies (2011–2015). Adverse outcomes were defined as indicated preterm delivery before 37 completed weeks due to preeclampsia, fetal growth restriction or other complications.

Results: First and second trimester maternal serum analytes were assessed in 1434 patients in 2 consecutive pregnancies. The presence of >1 extreme serum analyte in prior pregnancy significantly increased likelihood of >1 extreme analyte in subsequent pregnancy. The likelihood increased as number of prior extreme markers increased. In patients with normal outcomes and 2 or more extreme serum analytes in prior pregnancy, there was an increased incidence of adverse pregnancy outcomes in subsequent pregnancy with relative risk (RR) of 5.42 [95% CI 1.6–18.3].

Conclusions: The presence of more than 1 extreme serum marker in one pregnancy increases likelihood of recurrence in subsequent pregnancies. Risk of adverse outcomes in subsequent pregnancy can be evaluated based on biochemistry results as well as prior pregnancy outcomes.     

Prevention of unintended pregnancies by using emergency contraception: the differences between levonorgestrel and ulipristal acetate. A theoretical model using data from a survey on the use of emergency contraception in Spain, 2017

Objective: To estimate the differences in unintended pregnancies avoided using either levonorgestrel (LNG) or ulipristal acetate (UPA) emergency contraception (EC).

Design: Cross-sectional study.

Setting: Survey carried out in Spain.

Participants: 1000 Spanish women reporting unprotected sex in 2017.

Main measurements: EC use, reasons for not using EC, calculation of the number of unintended pregnancies avoided.

Results: 39% of Spanish women having had unprotected sex used EC. 61% of those women did not use EC and 11% did not know the existence of this resource. In 2017 the use of EC prevented 101,271 unintended pregnancies. If instead of using LNG every woman had used UPA another 15,979 additional pregnancies could have been prevented.

Conclusions: If all Spanish women having unprotected sex used EC we could expect a significant decrease in the number of unintended pregnancies and abortions. Using UPA instead of LNG would have a greater impact on that reduction with the corresponding benefit for women and society as a whole.
