Premature babies often need assistance to breathe but this can injure the lung and lead to abnormal lung development and long-term lung disease. We have recently identified 3 factors that we believe are fundamental to initiating this abnormal lung development. We will demonstrate that these 3 factors mediate abnormal lung development following lung injury at birth. This information can then be used to reduce the incidence and severity of chronic lung disease of the newborn.
Preterm birth, a birth before the 37th week of pregnancy occurs for fewer than 8% of mothers but is associated with two-thirds of all fetal deaths and deaths of liveborn infants in the first month after birth. In the late 1990s those deaths are concentrated among very preterm births i.e. births before the 32nd week of pregnancy. Infants born very preterm are very likely to need neonatal intensive care, quite likely to have had major respiratory, infectious or other problems after birth, and to n ....Preterm birth, a birth before the 37th week of pregnancy occurs for fewer than 8% of mothers but is associated with two-thirds of all fetal deaths and deaths of liveborn infants in the first month after birth. In the late 1990s those deaths are concentrated among very preterm births i.e. births before the 32nd week of pregnancy. Infants born very preterm are very likely to need neonatal intensive care, quite likely to have had major respiratory, infectious or other problems after birth, and to need readmission to hospital in the first year after birth. Surviving infants are more likely to have major impairments, minor impairments, and school difficulties than infants born at term. There is a substantial impact on families, health services and society of very preterm birth.There has been no reduction in the proportion of births which are preterm, or very preterm in the last 20 years, though advances in treatment and care have markedly improved the survival of preterm and very preterm infants. This study will investigate the role of previous pregnancies which did not result in births (miscarriages and terminations), together with other procedures such as D and C (dilatation and curettage), in subsequent preterm birth. As these previous pregnancy losses are all fairly common experiences any associated risk is important and this particular factor has not been studied in this way before. There is preliminary evidence that they may be associated with preterm birth and the study will be able to measure the associations while taking into account all the other known risk factors. Other possible risk factors such as experiencing violence in pregnancy or social factors acting at a neighbourhood level will also be included. If it is found that previous pregnancy losses are independently associated with preterm birth it will be possible to develop and test preventive strategies.Read moreRead less
Improving Respiratory Transition And Outcomes Of Newborn Infants

Summary
Effective mask ventilation is the most important intervention at birth that can reduce mortality and disability in term and preterm infants. I will develop strategies to help clinicians improve their resuscitation skills. I will also study new ways to better support babies’ transition after birth, to improve their short and long term outcomes. The results of this research will change the way newly born babies are cared for around the world.

Summary
Significant advances in medical care have increased survival of the tiniest and most premature babies. Those who have benefited from modern medicine are now in their mid-20s. We know they have more problems in childhood and adolescence compared with those born full term. However, we know little about their health problems in adulthood. This study will inform us of adult health problems in this vulnerable group and provide vital information about the best care for this increasing group of adults.
This research investigates the factors regulating the transition of the lung from the fluid filled organ in fetal life to the air filled organ required at birth. Many preterm babies fail this transition and in order to survive, their lungs often require mechanical ventilation, which has been suggested to cause lung injury. Using synchrotron generated X-rays, we can determine how particular resuscitation techniques are able to reduce this injury and promote aeration at birth.
Protecting Newborn Brains Via Innovative Monitoring Technology

Summary
This project aims to develop innovative brain monitoring technology which could help minimise brain damage in newborn babies with brain injuries, thereby delivering a healthier start to life. Such novel technology may automatically analyse babies’ brain activity and deliver instant detection of critical abnormalities, which could enable more effective treatment of brain injuries. Babies with reduced oxygen or blood supply to the brain and premature babies could benefit from such innovations.
Molecular Mechanisms Regulating Spontaneous Onset Of Human Labour

Summary
The single most important complication contributing to poor pregnancy and neonatal outcome is premature birth. If we are to provide the best possible start to life, improve perinatal health and reduce the risk of developing adult disease . A better understanding of labour is requisite to improving health care delivery during pregnancy and outcomes for both mother and baby. This reserach project will investigate the how labour-associated events are reguluated by nuclear proteins.

Reproductive biologists still cannot explain the molecular mechanisms that govern human birth. This lack of knowledge prevents the development of better moitoring and treament of complications of labour and delivery.

If we are to provide the best possible start to life and improve newborn health care delivery then we must: (1) better understand what triggers labour; (2) determine whether there are biomarkers that we can use to identify women at risk of early birth; and (3) identify new ways to delay birth. This is the overall objective of this research project. In particular, this project focuses on how the multiple events needed to achieve a successful outcome to pregnancy are coordinated at the time of birth.Read moreRead less
