Ultrasound Evaluation of the Cervix to Predict Failed Labor Induction.

Rev Bras Ginecol Obstet 2019 Aug 26;41(8):476-484. Epub 2019 Aug 26.

Department of Obstetrics and Gynecology, Faculdade de Medicina do ABC, Santo André, SP, Brazil.

Objective:  Labor induction does not always result in vaginal delivery, and can expose both the mother and the fetus to the risks inherent to the induction procedure or a possible cesarean section. Transvaginal sonography (TVS) of the cervix is a useful tool to predict prematurity; in the present study, this tool was used to evaluate postterm induction.

Methods:  We evaluated the ultrasound characteristics of the cervix (cervical length, cervical funneling, internal os dilation, the presence or absence of the cervical gland area [CGA], and the morphological changes of the cervix as a result of applying fundal pressure) before the onset of labor induction among women with postterm pregnancy to identify the possible predictors of failed labor induction.

Maternal Dietary Glycemic and Insulinemic Indexes Are Not Associated with Birth Outcomes or Childhood Adiposity at 5 Years of Age in an Irish Cohort Study.

J Nutr 2019 06;149(6):1037-1046

HRB Centre for Diet and Health Research, School of Public Health, Physiotherapy, and Sports Science, University College Dublin, Belfield, Dublin, Republic of Ireland.

Background: High maternal dietary glycemic index (GI) and glycemic load (GL) may be associated with adverse offspring birth and postnatal adiposity outcomes through metabolic programming, but the evidence thus far, mainly from studies conducted in high-risk pregnant populations, has been inconclusive. No study has examined the influence of maternal insulin demand [measured by food insulinemic index (II) and insulinemic load (IL)] on offspring outcomes.

Objectives: We investigated associations between maternal GI, GL, II, and IL and offspring birth outcomes and postnatal adiposity in a general pregnant population. Read More

Timing induction of labour at 41 or 42 weeks? A closer look at time frames of comparison: A review.

Midwifery 2018 Nov 11;66:111-118. Epub 2018 Aug 11.

Department of Obstetrics and Gynaecology, Amsterdam UMC, University of Amsterdam, Meibergdreef 9, Amsterdam, The Netherlands.

Background: Postterm pregnancy is associated with increased perinatal risk. The WHO defines postterm pregnancy as a pregnancy at or beyond 42 weeks + 0 days, though currently labour is induced at 41 weeks in many settings. Guidelines on timing of labour induction are frequently based on the Cochrane systematic review 'Induction of labour for improving birth outcomes for women at or beyond term' in which is concluded that a policy of induction of labour is associated with fewer adverse perinatal outcome and fewer Caesarean sections.

Surge of immune cell formation at birth differs by mode of delivery and infant characteristics-A population-based cohort study.

PLoS One 2017 14;12(9):e0184748. Epub 2017 Sep 14.

Division of Pediatrics, Department of Clinical Science, Intervention and Technology, Karolinska Institutet, Stockholm, Sweden.

Background: Birth by cesarean section is associated with increased risks of immune disorders. We tested whether establishment of immune function at birth relates to mode of delivery, taking other maternal and infant characteristics into account.

Methods And Findings: Using a prospectively collected database, we retrieved information on maternal and infant characteristics of 6,014 singleton infants delivered from February to April 2014 in Stockholm, Sweden, with gestational age ≥35 weeks, Apgar scores ≥7, and without congenital malformations or any neonatal morbidity.

Validation of maternal reported pregnancy and birth characteristics against the Medical Birth Registry of Norway.

PLoS One 2017 4;12(8):e0181794. Epub 2017 Aug 4.

Dept. of Clinical Science, University of Bergen, Bergen, Norway.

Studies using mothers' self-reported information on birth and pregnancy characteristics are common, but the validity of such data is uncertain. We evaluated questionnaire data from the RHINE III study on reproductive health provided by 715 mothers from Bergen, Norway, about their 1629 births between 1967 and 2010, using the Medical Birth Registry of Norway (MBRN) as gold standard. Validity of dichotomous variables (gender, preterm birth [<37 weeks' gestation], postterm birth [>42 weeks' gestation], induction of labour, forceps delivery, vacuum delivery, caesarean section, were assessed by sensitivity, specificity, positive and negative predictive values (PPV and NPV) and Cohen's kappa.

A mouse model of antepartum stillbirth.

Am J Obstet Gynecol 2017 10 12;217(4):443.e1-443.e11. Epub 2017 Jun 12.

Mouse Imaging Centre, The Hospital for Sick Children, Toronto, Ontario, Canada; Department of Physiology and Experimental Medicine, The Hospital for Sick Children, Toronto, Ontario, Canada; Department of Medical Biophysics, University of Toronto, Toronto, Ontario, Canada; Department of Obstetrics and Gynecology, University of Toronto, Toronto, Ontario, Canada. Electronic address:

Background: Many stillbirths of normally formed fetuses in the third trimester could be prevented via delivery if reliable means to anticipate this outcome existed. However, because the etiology of these stillbirths is often unexplained and although the underlying mechanism is presumed to be hypoxia from placental insufficiency, the placentas often appear normal on histopathological examination. Gestational age is a risk factor for antepartum stillbirth, with a rapid rise in stillbirth rates after 40 weeks' gestation. Read More

Unlabelled: This review presents the up-to-date information from published resources on the issue of Posterm pregnancy (Medline, Cochrane Database, ACOG, RCOG, SOGC) and complements the presented guidelines. The most of resources are using the term "postterm pregnancy" for pregnancy reaching or exceeding 42+0 weeks and days of gestation, while late pregnancy is defined as a period in between 41+0 and 41+6.The exact determination of gestational age is necessary for exact diagnosis and appropriate management of late and postterm pregnancy, because these pregnancies have increased risk of perinatal morbidity and mortality.

Study protocol of SWEPIS a Swedish multicentre register based randomised controlled trial to compare induction of labour at 41 completed gestational weeks versus expectant management and induction at 42 completed gestational weeks.

BMC Pregnancy Childbirth 2016 Mar 7;16:49. Epub 2016 Mar 7.

Gothenburg University, Perinatal centre, Department of Obstetrics and Gynecology, Institute of Clinical Sciences, Sahlgrenska Academy, Sahlgrenska University Hospital, East, S-416 85, Gothenburg, Sweden.

Background: Observational data shows that postterm pregnancy (≥42 gestational weeks, GW) and late term pregnancy (≥41 GW), as compared to term pregnancy, is associated with an increased risk for adverse outcome for the mother and infant. Standard care in many countries is induction of labour at 42 GW. There is insufficient scientific support that induction of labour at 41 GW, as compared with expectant management and induction at 42 GW will reduce perinatal mortality and morbidity without an increase in operative deliveries, negative delivery experiences or higher costs.
