The purple line and its association with cervical dilatation in labour: A systematic review and meta-analysis.

Background: There is a growing body of evidence that the presence and length of the purple line could represent a non-invasive method of estimating and determining labour progress.

Objectives: The primary outcome was to provide a systematic review and meta-analysis on the association between the purple line length and cervical dilatation in active labour. The secondary outcome was to determine the association between the purple line length and the fetal head descent, and to calculate the pooled mean length of the purple line at a cervical dilatation of 3-4 cm and at a cervical dilatation of 9-10 cm.

Induction of labour for predicted macrosomia: study protocol for the 'Big Baby' randomised controlled trial.

Introduction: Large-for-gestational age (LGA) fetuses have an increased risk of shoulder dystocia. This can lead to adverse neonatal outcomes and death. Early induction of labour in women with a fetus suspected to be macrosomic may mitigate the risk of shoulder dystocia.

The Incidence of and Predictors for Severe Perineal Trauma and Intact Perineum in Women Having a Waterbirth in England: A Hospital-Based Study.

To determine the incidence of and predictors for obstetric anal sphincter injuries (OASIS) and intact perineum in women giving birth in the water and compare with the general obstetric population. Data were retrospectively collected for women who had singleton cephalic presentation vaginal births in the water and the general obstetric population between August 2007 and December 2017. We identified 1,007 women who had a waterbirth and 36,924 women from the general obstetric population.

The SaTH risk-assessment tool for the prediction of emergency cesarean section in women having induction of labor for all indications: a large-cohort based study.

Purpose: To develop a risk-assessment model for the prediction of emergency cesarean section (CS) in women having induction of labor (IOL).

Methods: This was an observational cohort study of women with IOL for any indication between 2007 and 2013. Women induced for stillbirths and with multiple pregnancies were excluded.

Reversed twin-to-twin transfusion syndrome following successful laser therapy.

We report a case of severe twin-to-twin transfusion syndrome (TTTS) in which fetoscopic laser ablation was successfully performed at 21 weeks' gestation. Despite successful resolution of signs on ultrasound examination after a period of 7 weeks, the donor developed polyhydramnios whereas the 'initial' recipient maintained normal liquor volume, features suggestive of 'reversed TTTS'. Two live babies were delivered at 31 weeks' gestation with good neonatal outcome.
