Many women who experience gestational diabetes (GDM), gestational hypertension (GHT), pre-eclampsia (PE), have a spontaneous preterm birth (sPTB) or have an offspring born small/large for gestational age (SGA/LGA) do not meet the criteria for high-risk pregnancies based upon certain maternal risk factors. The aim of this study was to assess the predictive ability of an untargeted platform of over 700 metabolites to predict the above pregnancy-related disorders in two cohorts.View publication

Hyperglycaemia and hypoglycaemia are common in preterm infants and have been associated with increased risk of mortality and morbidity. Interventions to reduce risk associated with these exposures are particularly challenging due to the infrequent measurement of blood glucose concentrations, with the potential of causing more harm instead of improving outcomes for these infants.
Continuous glucose monitoring (CGM) is widely used in adults and children with diabetes to improve glucose control, but has not been approved for use in neonates. The REACT trial aimed to evaluate the efficacy and safety of CGM in preterm infants requiring intensive care.
This international, open-label, randomised controlled trial was done in 13 neonatal intensive care units in the UK, Spain, and the Netherlands. Infants were randomly assigned (1:1) to real-time CGM or standard care (with masked CGM for comparison). The primary efficacy outcome was the proportion of time sensor glucose concentration was 2·6–10 mmol/L for the first week of life. Safety outcomes related to hypoglycaemia (glucose concentrations <2·6 mmol/L) in the first 7 days of life.
Between July 4, 2016, and Jan 27, 2019, 182 infants were enrolled, 180 of whom were randomly assigned (85 to real-time CGM, 95 to standard care). 70 infants in the real-time CGM intervention group and 85 in the standard care group had CGM data and were included in the primary analysis.
Compared with infants in the standard care group, infants managed using CGM had more time in the 2·6–10 mmol/L glucose concentration target range. More infants in the standard care group were exposed to at least one episode of sensor glucose concentration of less than 2·6 mmol/L for more than 1 h than those in the intervention group. There were no serious adverse events related to the use of the device or episodes of infection.
Real-time CGM can reduce exposure to prolonged or severe hyperglycaemia and hypoglycaemia. Further studies using CGM are required to determine optimal glucose targets, strategies to obtain them, and the potential effect on long-term health outcomes.View publication

Researchers found evidence to support the theory of the placenta as a ‘dumping ground’ for genetic defects, whereas the fetus corrects or avoids these errors. The findings provide a clear rationale for studying the association between genetic aberrations and birth outcomes, in order to better understand problems such as premature birth and stillbirth.

Delivering a large baby (usually defined as above 4Kg or 90th birth weight centile) has been associated with complications such shoulder dystocia – after the vaginal delivery of the head, the baby’s shoulder gets stuck behind the mother’s pubic bone. This could lead to the baby with fractured bones and lack of oxygen during the delivery. There may be then a potential need for emergency caesarean section and neonatal unit admission.
Predicting the delivery of a large baby can be difficult and there is currently no standard screening programme to predict these complications.
Screening more than 100,000 patients, Cambridge researchers found that offering a scan to all women at 36 weeks could increase the detection of delivering a large baby and the prediction was more effective for very large babies (above 4.5Kg). However, the screening could not identify shoulder dystocia to the same effect or enough evidence to predict which babies could have other complications.
More evidence is needed on the benefit of introducing another ultrasound for all women, to help identify any potential problems before labour as well as predict large babies.View publication

Women who don’t need pain relief during childbirth may have a key genetic variant that acts as a natural epidural. Supported by the NIHR Cambridge BRC, researchers investigated why some women experience different levels of pain during childbirth.
Women who did not require any pain relief during the birth of their first child took part in a study to understand their pain threshold. This included applying heat and pressure to their arms and putting their hands in icy water. They were then measured against a control group of women were who were given pain relief during childbirth.
They found the group the women who didn’t need any pain relief had a high pain threshold than those of the control group. Their genetic cold was then sequenced and found these women had a higher-than-expected prevalence of a rare variant of the gene KCNG4. This gene acts as a gate, controlling the electric signal that flows along our nerve cells. This could be the reason why these women did not require pain relief during childbirth.

The placenta is the interface between the mum and the fetus and supports the growth of the baby in the womb. Abnormal function of the placenta is associated with poor pregnancy outcome, including maternal and infant diseases and deaths. In turn, placental dysfunction could be due to viral infections, which are known to cause organ failure. We investigated whether viral infection of the placenta is associated with diseases of human pregnancy related to poor placental function, such as pre-eclampsia (hypertensive disorder in the mother) and fetal growth restriction (impaired growth of the fetus during pregnancy).
Using samples from more than 5,000 pregnancies and data available in the literature, we demonstrated that the presence of inherited human herpesvirus 6 (HHV-6) DNA in the feto-placental unit is associated with an increased risk of the mother to develop pre-eclampsia. The virus can be passed to the fetus and the placenta from both the mother and the father. Importantly, our study did not identify any other viral associations with the 2 studied conditions. HHV-6 was the only clear viral signal observed in a large number of placental samples from pathological and normal pregnancies.
Pre-eclampsia is a condition characterized by high maternal blood pressure and protein levels in the urine in the second half of pregnancy. It represents a major determinant of the global burden of disease. Although pre-eclamspia is known to be associated with poor development and function of the placenta, the causes of placental insufficiency are not fully understood. Identifying those will help us to understand and treat this condition, which affects 5-8% of all pregnant women and is responsible for over 75,000 maternal deaths and 500,000 fetal deaths worldwide every year. Our work demonstates that viral infection of the placenta is not a major cause of pre-eclampsia and that a small proportion of cases is likely to be due to the presence of HHV-6 in the feto-placental unit.View publication

This paper looks at somatic mutation (changes in the DNA) in healthy human tissue in the endometrium (womb lining) and provides insights into the earliest stages of uterine cancer development, which is the fourth most common cancer in women in the UK.
Many cells in the inner lining of the uterus carry ‘cancer-driving’ mutations that frequently arise early in life. Using whole-genome sequencing to better understand the genetic changes in healthy endometrial tissue, the researchers found that a high proportion of cells carry driver mutations, even though they appear completely normal under the microscope. Furthermore the team found that many of these driver mutations appear to have arisen early in life, in many cases during childhood.View publication

Fetal growth restriction (FGR) means that the fetus fails to grow according to its growth potential. The condition is a major cause of stillbirth, neonatal illness and death. Maternal risk factors and ultrasound measurements alone are not effective in screening for fetal growth restriction. Biomarkers in the pregnant woman’s blood could possibly improve screening for FGR.
Using serial maternal serum samples from the Pregnancy Outcome Prediction (POP) study, the research team identified metabolites that were predictive of FGR at term. These were used to calculate a ratio that clearly improves the prediction of FGR over currently known risk factors. They successfully validated the finding in plasma samples from a demographically different Born in Bradford (BiB) study.
Together with ultrasound measurements, the metabolite ratio could possibly be used to improve late pregnancy screening for fetal growth restriction. Screen-positive women could be offered enhanced monitoring and targeted induction of labour to prevent adverse effects associated with FGR.View publication

During pregnancy a complex interaction between the mother and the embryo/fetus takes part to secure placental provision of nutrients to the fetus. Human models of this interaction, involving so called trophoblast invasion, had not been established, making it difficult to study this process, that results in life threatening diseases when it goes wrong.
The laboratory of Aschley Moffett, who led this research, established a new organoid model for human trophoblast/placenta development. Our contribution was LC-MS/MS showing that this model faithfully produced pregnancy related hormones.
This organoid model will be transformative for studying human placental development and for investigating trophoblast interactions with the local and systemic maternal environment.View publication

Despite the relative ease with which breech presentation can be identified through ultrasound screening, the assessment of foetal presentation at term is often based on clinical examination only. Due to limitations in this approach, many women present in labour with an undiagnosed breech presentation, with increased risk of foetal morbidity and mortality. This study sought to determine the cost effectiveness of universal ultrasound scanning for breech presentation near term (36 weeks of gestational age [wkGA]) in nulliparous women.View publication
