Authors:
Deirdre J Murphy

Best Pract Res Clin Obstet Gynaecol 2019 Feb 10. Epub 2019 Feb 10.

Trinity College, University of Dublin, Ireland. Electronic address:

Women undergo operative vaginal delivery (OVD) as an alternative to caesarean section when complications arise in the second stage of labour. The perinatal mortality associated with OVD is very low, and most of the perinatal morbidity is minor. However, when serious adverse events occur, such as traumatic birth injury, shoulder dystocia, cerebral palsy and perinatal death, there are medico-legal implications. Read More

Evidence in support of the International Association of Diabetes in Pregnancy study groups' criteria for diagnosing gestational diabetes mellitus worldwide in 2019.

Am J Obstet Gynecol 2019 Jan 22. Epub 2019 Jan 22.

Mater Health and Mater Research, University of Queensland, Queensland, Australia.

Gestational diabetes mellitus, the most frequent medical complication of pregnancy, affects 5-6% of women in the United States with the use of the currently predominant Carpenter-Coustan criteria, which still represent the preferred approach of the American College of Obstetricians and Gynecologists. Alternative criteria proposed by the International Association of Diabetes in Pregnancy Study Groups would likely increase gestational diabetes mellitus prevalence to 15-20%, because of both a 1-step testing policy and the requirement for only 1 elevated glucose value for diagnosis. Increasing gestational diabetes mellitus prevalence relates to older maternal age and the increasing prevalence of overweight and obesity. Read More

The impact of extending the second stage of labor to prevent primary cesarean delivery on maternal and neonatal outcomes.

Am J Obstet Gynecol 2019 Feb 25;220(2):191.e1-191.e7. Epub 2018 Oct 25.

Department of Obstetrics and Gynecology, Rambam Health Care Campus, Haifa, Israel; Bruce Rappaport Faculty of Medicine, Technion-Israel Institute of Technology, Haifa, Israel. Electronic address:

Background: A low rate of primary cesarean delivery is expected to reduce some of the major complications that are associated with a repeat cesarean delivery, such as uterine rupture, adhesive placental disorders, hysterectomy, and even maternal death. Since 2014, and in alignment with the American College of Obstetricians and Gynecologists and the Society for Maternal-Fetal Medicine, we changed our approach to labor dystocia, defined as abnormal progression of labor, by allowing a longer duration of the second stage of labor.

Objective: To examine the effect of prolonging the second stage of labor on the rate of cesarean delivery, and maternal and neonatal outcomes. Read More

Early screening for gestational diabetes mellitus is not associated with improved pregnancy outcomes: an observational study including 9795 women.

Diabetes Metab 2018 Nov 28. Epub 2018 Nov 28.

Paris 13 university, Sorbonne Paris Cité, AP-HP, Jean-Verdier hospital, department of obstetrics and gynecology, Bondy, France.

Aims: In addition to screening for hyperglycaemia during pregnancy after 24 weeks of gestation (WG), the current guidelines also suggest screening in early pregnancy and referring women with early gestational diabetes mellitus (eGDM) or overt diabetes (OD) for immediate care. Our aim was to evaluate this strategy.

Methods: This study evaluated, at our hospital (2012-2016), whether the incidence of a predefined composite outcome (preeclampsia, large-for-gestational-age infant, shoulder dystocia) and secondary outcomes was different when women were screened only after 22WG ('late screening only') or before 22WG and treated for eGDM or OD if present, with repeat screening after 22WG if absent ('early ± late screening').

Outcomes associated with trial of labor after cesarean in women with one versus two prior cesarean deliveries after a change in clinical practice guidelines in an academic hospital.

J Matern Fetal Neonatal Med 2019 Feb 6:1-6. Epub 2019 Feb 6.

a Department of Obstetrics and Gynecology, Division of Maternal Fetal Medicine , Baylor College of Medicine , Houston , TX , USA.

Objective: In 2010, the American College of Obstetricians & Gynecologists (ACOG) published a new clinical practice guideline on trial of labor after cesarean (TOLAC) that was considered less restrictive. It allowed for offering TOLAC to women with two prior cesarean deliveries, even without a prior vaginal delivery, and for labor induction. As a result, our hospital, a public tertiary care academic center, updated our TOLAC practice guideline to reflect ACOG's new recommendations. Read More

Foetal Macrosomia and Foetal-Maternal Outcomes at Birth.

J Pregnancy 2018 8;2018:4790136. Epub 2018 Aug 8.

Department of Obstetrics and Gynecology, Sundsvall County Hospital, Sundsvall 85186, Sweden.

To investigate how macrosomia affects foetal-maternal birth outcomes, we conducted a retrospective cohort study of singleton pregnant women who gave birth at gestational age ≥37+0 weeks. The patients were divided into three groups according to birth weight: "macrosomia" group, ≥4500 g, n=285; "upper-normal" group, 3500-4499 g, n=593; and "normal" group, 2500-3499 g, n=495. Foetal-maternal and delivery outcomes were compared among the three groups after adjustment for confounders. Read More

Shoulder dystocia and range of head-body delivery interval (HBDI): The association between prolonged HBDI and neonatal outcomes: Protocol for a systematic review.

Eur J Obstet Gynecol Reprod Biol 2018 Oct 11;229:82-87. Epub 2018 Aug 11.

Centre for Midwifery, Child and Family Health, Faculty of Health, University of Technology Sydney, Sydney, NSW, Australia.

Objective: Shoulder dystocia (SD) is an obstetric emergency which if not carefully diagnosed and managed, can contribute to lifelong neonatal morbidities. Despite current guidelines on the definition of SD (impaction of the fetal shoulder behind the maternal symphysis pubis and need for ancillary manoeuvres or head-body delivery interval (HBDI) >60 s) its accurate diagnosis requires clinical expertise as well as overall consideration of feto-maternal condition. Based on the literature available, our study aims to determine (1) the range of HBDI as an indicator of SD and (2) the neonatal complications occurring following prolonged HBDI in normal or SD-complicated births.

Metformin for women who are overweight or obese during pregnancy for improving maternal and infant outcomes.

Cochrane Database Syst Rev 2018 Jul 24;7:CD010564. Epub 2018 Jul 24.

School of Paediatrics and Reproductive Health, Discipline of Obstetrics and Gynaecology, The University of Adelaide, Women's and Children's Hospital, 72 King William Road, Adelaide, South Australia, Australia, 5006.

Background: There has been considerable interest in providing antenatal dietary and lifestyle advice for women with obesity or who are overweight during pregnancy, as a strategy to limit gestational weight gain and improve maternal and infant health. However, such antenatal interventions appear to have a modest effect on gestational weight gain and other clinical pregnancy and birth outcomes and additional strategies are required.Metformin is an oral insulin-sensitising medication that acts to decrease blood glucose concentrations.

Clinical features of a fatal shoulder dystocia: The hypovolemic shock hypothesis.

Med Hypotheses 2018 Sep 6;118:139-141. Epub 2018 Jul 6.

Gynecologic and Obstetric Department, Nuovo Ospedale delle Apuane, Via Enrico Mattei 21, Massa Carrara, Italy.

Shoulder dystocia is a rare but severe obstetric complication associated with an increased risk of brachial plexus palsies, fractures of the clavicle and humerus, hypoxic-ischemic encephalopathy and, rarely, neonatal death. Here we describe a fatal case of shoulder dystocia in a term newborn, although labor was uneventful, fetal heart rate tracing was normal until the delivery of the head and the head-to-body delivery interval (HBDI) occurred within 5 min. Full resuscitation was performed for 35 min without success. Read More

Large-for-Gestational-Age Neonates in Type 1 Diabetes and Pregnancy: Contribution of Factors Beyond Hyperglycemia.

Diabetes Care 2018 08;41(8):1821-1828

Department of Diabetes, Endocrinology & Metabolism and the Northern Clinical School, Faculty of Medicine and Health, The University of Sydney, Royal North Shore Hospital, St Leonards, Sydney, New South Wales, Australia.

Despite significant reductions in serious adverse perinatal outcomes for women with type 1 diabetes in pregnancy, the opposite effect has been observed for fetal overgrowth and associated complications, such as neonatal hypoglycemia, shoulder dystocia, and admission to the neonatal intensive care unit. In addition, infants born large for gestational age (LGA) have an increased lifetime risk of obesity, diabetes, and chronic disease. Although exposure to hyperglycemia plays an important role, women who seemingly achieve adequate glycemic control in pregnancy continue to experience a greater risk of excess fetal growth, leading to LGA neonates and macrosomia.
