OXPLUS  (Oxford Placental Ultrasound STUDY)

Who can participate? Pregnant women aged 18 years or above who are in the first few months of pregnancy and attending their routine 11-14-week (‘first trimester’) ultrasound scan at the John Radcliffe Hospital, Women’s Centre, Oxford.  

Summary: The aim of this study is to establish if a new piece of computer software — called the ‘OxNNet toolkit’ — can predict which babies will not grow as well as they should using information gained from a 3D ultrasound scan about the size of the placenta and its blood flow, together with other known risk factors.

PURE (Pregnancy Ultrasound ResourcE)

Who can participate? Any pregnant women, over 18 years old at their ultrasound appointments.

Summary: We are working to create automatic ultrasound systems requiring minimal control by a health professional so that the scan machine will automatically identify and take measurements of babies. In order to do so, we are asking volunteers for their permission to have their scan images recorded, and for the sonographer to track her/his eye-movements while the scan is being performed. This study will benefit women living in disadvantaged areas where there is a lack of skilled ultrasound operators, meaning scans are not available as part of routine clinical care.

PURFECT (Perception Ultrasound for Reassuring Fetal Echo Clinical Trainees)

Who can participate? Pregnant women who attend for their anomaly ultrasound appointment (18+0 – 20+6wks).

Summary: We are working to develop ultrasound assistive software (PURFECT) to aid sonographers in gaining the best possible images and measurements when scanning a baby. It is hoped that this tool will reassure newly qualified sonographers and also support more experienced sonographers to scan more efficiently.

We are asking volunteers to have an extra scan which is recorded, to enable sonographers to use the assistive software. Sonographers are being asked to scan using this new tool which will provide visual guidance during the examination. It will also record where sonographers are looking on the screen while performing the scan. The sonographers are then asked for feedback as to how useful they found it.

CAIFE (Clinical Artificial Intelligence Fetal Echocardiography)

Who can participate? Pregnant women (aged 18 years or above), attending an ultrasound scan and/or fetal cardiology appointment in the Obstetric Ultrasound Department at the collaborating hospitals.

Summary: We are working to create an ultrasound systems which can recognise the difference between a healthy and unhealthy fetal heart using machine learning. Detection of congenial heart defects during pregnancy allows early diagnosis and planning for treatment post-delivery.

INSIGHT (Investigating hormones triggering the onset of sustained lactation)

Who can participate? Pregnant women intending to breastfeed in Oxfordshire area. 

Summary: Hormones such as prolactin and progesterone play a major role in the breastfeeding process and trigger the onset of milk production within the first few days after childbirth. However, the hormone levels required to stimulate milk production are unknown. At LRF OCEHL we are running this vital study to develop normal ranges for milk producing hormones. This study will help us understand why some breastfeeding mothers have delayed milk production or produce limited quantities of milk. View the INSIGHT Study leaflet.

Giant PANDA (Pregnancy ANtihypertensive Drugs)

Who can participate? Pregnant women between 11+0 – 34+6 weeks, over 18 years old with a diagnosis of pregnancy hypertension (Chronic/pregnancy induced hypertension/Pre-eclampsia).Clinicians’ decision to initiate antihypertensive medication. 

Women who have a contraindication to either Labetalol or Nifedipine and are already taking both medications are excluded from participating in this study. 

Summary: The aim of this study is to evaluate the effect of different antihypertensive drugs in women with chronic/gestational hypertension or pre-eclampsia on maternal and fetal/neonatal outcomes. The primary objective is to evaluate if treatment with nifedipine (calcium channel blocker), compare to labetalol (mixed alpha/beta blocker) in women with pregnancy hypertension, reduces severe maternal hypertension without increasing fetal or neonate adverse events.

MRC Study (for understanding and predicting pre-eclampsia)

Who can participate? Pregnant women both with and without pre-eclampsia and also non pregnant women.

Summary: The purpose of the study is to find out more about what causes pre-eclampsia and how to predict it. We compare the results of certain tests on blood, urine and placental samples from pregnant women with pre-eclampsia and those without. We also study blood and urine from non pregnant, healthy women.

Intervention or expectant management for early onset selective fetal growth restriction in monochorionic twin pregnancy

Who can participate? Women who are currently pregnant (16-23 weeks) with a monochorionic (identical sharing one placenta) twin pregnancy complicated by sFGR/sIUGR (one of the babies is smaller) or have had a sFGR/sIUGR affected monochorionic twin pregnancy in the last 3 years to take part in this study.

Summary: The UK has approximately 11,000 twin pregnancies per year with a third of these sharing a placenta (MC twins). MC twin pregnancy presents extra risks to both the mother and the babies, with some babies dying during pregnancy or shortly after birth. Often this is due to a complication called selective Fetal Growth Restriction (sFGR), where one twin is smaller than the other. This study aims to gain a better understanding of the outcomes for sFGR in MC twin pregnancies managed in a variety of ways.

RaDaR (Kidney disease and pregnancy)

Who can participate? Women with chronic kidney disease who have, or have had, a pregnancy.

Summary: The National Registry of Rare Kidney Diseases (RaDaR) is a research initiative by UK kidney specialist (the Renal Association and the UK Renal Registry). It is designed to gather information from patients with rare kidney disease and in particular women with chronic kidney disease (CKD). The group aims to look into how women with CKD cope with pregnancy and what can be done to improve care.

Pre-eclampsia Study

Study of placental particle shedding and the maternal inflammatory response in pre-eclampsia

Who can participate? Women with pre-eclampsia and women without pre-eclampsia.

Summary: The Purpose of the study is to find out more about what causes and how to predict pre-eclampsia. We need to compare the results of certain tests on blood and placental samples from pregnant women with pre-eclampsia with those of women without pre-eclampsia.

SMA (Spinal Muscular Atrophy Study)

The aim of this population-based research study on newborn genetic screening for spinal muscular atrophy (SMA) is to evaluate the uptake and feasibility in the UK.

Who can participate? We are inviting women who are more than 18 weeks pregnant, or have given birth in the last 28 days, to be part of this study with their newborn babies.

Summary: Our newborn screening study aims to make it possible to detect SMA within days of birth, before symptoms develop, so that any affected newborn can receive diagnosis and treatment at the earliest possible opportunity. SMA is not currently screened for as part of the newborn screening programme. This screening test can be done on the blood spot that is already being taken as part of the standard newborn screening programme. This means no extra blood samples will be needed.
