Stillbirth in term and late term gestations in Stockholm during a 20-year period, incidence and causes.

PLoS One 2021 25;16(5):e0251965. Epub 2021 May 25.

Department of Women´s and Children´s Health, Karolinska Institutet, Stockholm, Sweden.

Introduction: The incidence of stillbirth has decreased marginally or remained stable during the past decades in high income countries. A recent report has shown Stockholm to have a lower incidence of stillbirth at term than other parts of Sweden. The risk of antepartum stillbirth increases in late term and postterm pregnancies which is one of the factors contributing to the current discussion regarding the optimal time of induction of labor due to postterm pregnancy.

Integrated trajectories of the maternal metabolome, proteome, and immunome predict labor onset.

Sci Transl Med 2021 May;13(592)

Department of Surgery, Stanford University School of Medicine, Palo Alto, CA 94305, USA.

Estimating the time of delivery is of high clinical importance because pre- and postterm deviations are associated with complications for the mother and her offspring. However, current estimations are inaccurate. As pregnancy progresses toward labor, major transitions occur in fetomaternal immune, metabolic, and endocrine systems that culminate in birth. Read More

Efficacy and safety of oral misoprostol versus transvaginal balloon catheter for labor induction: An observational study within the SWEdish Postterm Induction Study (SWEPIS).

Acta Obstet Gynecol Scand 2021 Mar 25. Epub 2021 Mar 25.

Center of Perinatal Medicine and Health, Department of Obstetrics and Gynecology, Institute of Clinical Sciences, University of Gothenburg, Gothenburg, Sweden.

Introduction: Induction of labor is increasing. A common indication for induction of labor is late term and postterm pregnancy at 41 weeks or more. We aimed to evaluate if there are any differences regarding efficacy, safety, and women's childbirth experience between oral misoprostol and transvaginal balloon catheter for cervical ripening in women with a low-risk singleton pregnancy and induction of labor at 41 to 42 weeks of gestation.

PLoS Med 2021 01 21;18(1):e1003491. Epub 2021 Jan 21.

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

Background: Adverse birth outcomes are major causes of morbidity and mortality during childhood and associate with a higher risk of noncommunicable diseases in adult life. Maternal periconception and antenatal nutrition, mostly focusing on single nutrients or foods, has been shown to influence infant birth outcomes. However, evidence on whole diet that considers complex nutrient and food interaction is rare and conflicting. Read More

Objective: To develop models to predict vaginal delivery in low-risk, nulliparous women contemplating elective induction of labor or expectant management at 39 weeks of gestation.

Methods: We conducted a secondary analysis of a randomized controlled trial of planned elective induction of labor at 39 weeks of gestation compared with expectant management for low-risk nulliparous women. Two groups were included for this analysis: 1) women who were randomized to the induction of labor group and underwent elective induction at 39 0/7-39 4/7 weeks of gestation and 2) women who were randomized to the expectant management group who experienced spontaneous labor or medically indicated delivery (including postterm).

Agreement between antenatal gestational age by ultrasound and clinical records at birth: A prospective cohort in the Brazilian Amazon.

PLoS One 2020 14;15(7):e0236055. Epub 2020 Jul 14.

Department of Nutrition, School of Public Health, University of São Paulo, São Paulo, Brazil.

Obstet Gynecol Surv 2020 Jan;75(1):61-72

Assistant Professor, Third Department of Obstetrics and Gynaecology, Faculty of Medicine, Aristotle University of Thessaloniki, Thessaloniki, Greece.

Importance: Induction of labor (IOL) is a common obstetric intervention that stimulates the onset of labor using artificial methods.

Objective: The aim of this study was to summarize and compare recommendations from 4 national or international medical societies on the IOL.

Evidence Acquisition: A descriptive review was conducted of major published guidelines on IOL: the American College of Obstetricians and Gynecologists' "Induction of Labor" and "Management of Late-Term and Postterm Pregnancies," the guidelines of the Society of Obstetricians and Gynaecologists of Canada (SOGC) on "Induction of Labour," those of the National Institute for Health and Care Excellence (NICE) on "Inducing Labour," and the World Health Organization's (WHO's) "Recommendations for Induction of Labour" and "WHO Recommendations: Induction of Labour at or Beyond Term.

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.

General Movements and Outcome in Children with Birthweights ≤ 500 Grams at Age 5 to 6 Years.

Z Geburtshilfe Neonatol 2020 Apr 7;224(2):86-92. Epub 2019 Aug 7.

Paediatrics, Ludwig-Maximilians-Universität München, perinatal center Großhadern, München.

Background: The prognosis of long-term outcome in the delicate subgroup of preterm infants born with a birthweight ≤ 500 g is difficult. We wanted to determine whether general movements (GMs) correlate with outcome at 5 to 6 years of age in preterm children with birthweights ≤500 g.

Methods: GMs were assessed up to 20 weeks postterm age in a cohort of infants born consecutively in our unit between 1998 until 2003. Read More

Pregnancy after bariatric surgery and adverse perinatal outcomes: A systematic review and meta-analysis.

PLoS Med 2019 08 6;16(8):e1002866. Epub 2019 Aug 6.

Institute of Health & Society, Newcastle University, Newcastle upon Tyne, United Kingdom.

Background: Women who undergo bariatric surgery prior to pregnancy are less likely to experience comorbidities associated with obesity such as gestational diabetes and hypertension. However, bariatric surgery, particularly malabsorptive procedures, can make patients susceptible to deficiencies in nutrients that are essential for healthy fetal development. The objective of this systematic review and meta-analysis is to investigate the association between pregnancy after bariatric surgery and adverse perinatal outcomes. Read More
