Continuation versus discontinuation of intravenous oxytocin in the active phase of labour.

This is a protocol for a Cochrane Review (intervention). The objectives are as follows: To assess the effects of discontinuing intravenous oxytocin stimulation in pregnant women during the active phase of induced or augmented labour.

Data integrity of 14 randomised controlled trials.

Background: A review of the literature on iron treatments for iron-deficient anaemia in pregnancy indicated duplication of baseline and outcome tables in two separate randomised controlled trials (RCTs) that share only a single author.

Aim: To assess the integrity of randomised clinical trials from Dr A.M.

The carbon footprint of different modes of birth in the UK and the Netherlands: An exploratory study using life cycle assessment.

Objective: To compare the carbon footprint of caesarean and vaginal birth.

Design: Life cycle assessment (LCA).

Setting: Tertiary maternity units and home births in the UK and the Netherlands.

Checklist to assess Trustworthiness in RAndomised Controlled Trials (TRACT checklist): concept proposal and pilot.

Objectives: To propose a checklist that can be used to assess trustworthiness of randomized controlled trials (RCTs).

Design: A screening tool was developed using the four-stage approach proposed by Moher et al. This included defining the scope, reviewing the evidence base, suggesting a list of items from piloting, and holding a consensus meeting.

Feasibility of a RCT of techniques for managing an impacted fetal head during emergency caesarean section: the MIDAS scoping study.

Background: Second-stage caesarean sections, of which there are around 34,000 per year in the UK, have greater maternal and perinatal morbidity than those in the first stage. The fetal head is often deeply impacted in the maternal pelvis, and extraction can be difficult. Numerous techniques are reported, but the superiority of one over another is contentious and there is no national guidance.

Induction of labour at or near term for suspected fetal macrosomia.

Background: Women with a suspected large-for-dates fetus or a fetus with suspected macrosomia (birthweight greater than 4000 g) are at risk of operative birth or caesarean section. The baby is also at increased risk of shoulder dystocia and trauma, in particular fractures and brachial plexus injury. Induction of labour may reduce these risks by decreasing the birthweight, but may also lead to longer labours and an increased risk of caesarean section.

Pregnancy outcomes and vaccine effectiveness during the period of omicron as the variant of concern, INTERCOVID-2022: a multinational, observational study.

Background: In 2021, we showed an increased risk associated with COVID-19 in pregnancy. Since then, the SARS-CoV-2 virus has undergone genetic mutations. We aimed to examine the effects on maternal and perinatal outcomes of COVID-19 during pregnancy, and evaluate vaccine effectiveness, when omicron (B.

Recruitment of pregnant women to randomised trials of COVID 19 treatments, and pharmaceutical treatments received outside such trials: A research article.

Objectives: To document how many pregnant women with COVID-19 reported in the literature had participated in randomised trials, what treatments they received outside such trials and compare the latter with evidence-based treatment recommendations.

Study Design: A systematic review of observational studies.

Methods: Two clinical trial registries were searched to identify COVID-19 trials open to pregnant women.

Perinatal and 2-year neurodevelopmental outcome in late preterm fetal compromise: the TRUFFLE 2 randomised trial protocol.

Introduction: Following the detection of fetal growth restriction, there is no consensus about the criteria that should trigger delivery in the late preterm period. The consequences of inappropriate early or late delivery are potentially important yet practice varies widely around the world, with abnormal findings from fetal heart rate monitoring invariably leading to delivery. Indices derived from fetal cerebral Doppler examination may guide such decisions although there are few studies in this area.

Impacted fetal head during second stage Caesarean birth: A prospective observational study.

Objective: To determine the incidence of, and complication rates from, impacted fetal head at full dilatation Caesarean birth in the UK, and record what techniques were used.

Design: Prospective observational study using the UK Obstetric Surveillance System (UKOSS).

Setting: 159 (82%) of the 194 UK hospitals with obstetric units.

COVID-19 and pregnancy: A comparison of case reports, case series and registry studies.

Background: Selection, outcome and publication biases are well described in case reports and case series but may be less of a problem early in the appearance of a new disease when all cases might appear to be worth publishing.

Objective: To use a prospectively collected database of primary sources to compare the reporting of COVID-19 in pregnancy in case reports, case series and in registries over the first 8 months of the pandemic.

Study Design: MEDLINE, Embase and Maternity and Infant Care databases were searched from 22 March to 5 November 2020, to create a curated list of primary sources.

Routine ultrasound for fetal assessment before 24 weeks' gestation.

Background: Ultrasound examination of pregnancy before 24 weeks gestation may lead to more accurate dating and earlier diagnosis of pathology, but may also give false reassurance. It can be used to monitor development or diagnose conditions of an unborn baby. This review compares the effect of routine or universal, ultrasound examination, performed before 24 completed weeks' gestation, with selective or no ultrasound examination.

Preeclampsia and COVID-19: results from the INTERCOVID prospective longitudinal study.

Background: It is unclear whether the suggested link between COVID-19 during pregnancy and preeclampsia is an independent association or if these are caused by common risk factors.

Objective: This study aimed to quantify any independent association between COVID-19 during pregnancy and preeclampsia and to determine the effect of these variables on maternal and neonatal morbidity and mortality.

Study Design: This was a large, longitudinal, prospective, unmatched diagnosed and not-diagnosed observational study assessing the effect of COVID-19 during pregnancy on mothers and neonates.

Concerns about Data Integrity of 22 Randomized Controlled Trials in Women's Health.

Objective: During a review on postpartum hemorrhage, we identified randomized controlled trials (RCTs) of one author conducted at the same time and place for the same condition, with large differences in baseline characteristics. We assessed the data integrity of the RCTs of this author.

Study Design: We undertook a focused analysis of the data integrity of all RCTs published by Dr.

An investigation of seven other publications by the first author of a retracted paper due to doubts about data integrity.

Background: In 2019, a randomized controlled trial (RCT) authored by Dr. Ismail was retracted due to concerns about data integrity. Since there are no policies in place to investigate other publications of authors of retracted studies, we investigated Dr.

Fetal umbilical artery Doppler as a tool for universal third trimester screening: A systematic review and meta-analysis of diagnostic test accuracy.

The objective of this study was to investigate the accuracy of universal third trimester umbilical artery (UA) Doppler to predict adverse pregnancy outcome at term. We searched Medline, EMBASE, the Cochrane library and ClinicalTrials.gov from inception to October 2020 and we also analyzed previously unpublished data from a prospective cohort study of nulliparous women, the Pregnancy Outcome Prediction (POP) study.

Evaluating the influence of progesterone concentration and time of exposure on in vitro endometrial decidualisation.

This study aimed to evaluate the influence of progesterone (concentration and time of exposure) on endometrial decidualisation using an in vitro model cell line: Human Endometrial Stromal Cells (HESCs). HESCs exposed to progesterone (1 and 10 μM) had higher percentages of decidualised cells and higher expression of the decidual marker (Insulin Like Growth Factor Binding Protein 1 (IGFBP1)) compared with those exposed to (0.1 μM).

Universal late pregnancy ultrasound screening to predict adverse outcomes in nulliparous women: a systematic review and cost-effectiveness analysis.

Background: Currently, pregnant women are screened using ultrasound to perform gestational aging, typically at around 12 weeks' gestation, and around the middle of pregnancy. Ultrasound scans thereafter are performed for clinical indications only.

Objectives: We sought to assess the case for offering universal late pregnancy ultrasound to all nulliparous women in the UK.

Haemostatic and thrombo-embolic complications in pregnant women with COVID-19: a systematic review and critical analysis.

Background: As pregnancy is a physiological prothrombotic state, pregnant women may be at increased risk of developing coagulopathic and/or thromboembolic complications associated with COVID-19.

Methods: Two biomedical databases were searched between September 2019 and June 2020 for case reports and series of pregnant women with a diagnosis of COVID-19 based either on a positive swab or high clinical suspicion where no swab had been performed. Additional registry cases known to the authors were included.
