Summary
A series of epidemiological studies have demonstrated that life expectancy and the risk of developing a range of adult diseases such as heart disease, diabetes mellitus and obesity, are related to weight and size at birth. It appears that genetic and environmental factors interact during pregnancy to determine the growth rate of the embryo and fetus and result in a permanent programming of the development of fetal organs and tissues which may result in the onset of disease in adult life. It is w ....A series of epidemiological studies have demonstrated that life expectancy and the risk of developing a range of adult diseases such as heart disease, diabetes mellitus and obesity, are related to weight and size at birth. It appears that genetic and environmental factors interact during pregnancy to determine the growth rate of the embryo and fetus and result in a permanent programming of the development of fetal organs and tissues which may result in the onset of disease in adult life. It is well established that babies born to mothers who develop diabetes in pregnancy are bigger at birth and are at greater risk of developing obesity in childhood. Paradoxically several major studies of human populations exposed to deprivation during pregnancy have shown that children born to mothers who experience undernutrition in pregnancy may also develop obesity in adult life. A new hormone has recently been identified which acts as a signal of fat mass and which plays a major role in the regulation of body weight and energy expenditure in the adult. We propose to define the role of this hormone before birth and to determine whether its production or action is altered by an increase or a decrease in fetal nutrition. In particular, we will investigate whether perturbations in the metabolic environment of the fetus program an increased production of this hormone or resistance to its actions after birth. These studies will increase our understanding of what adaptive changes before birth may relate to an increased likelihood of obesity after birth.Read moreRead less
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.

Summary
Progress in the care of the unborn baby, and thus optimisation of life-long health, will only come with a greater understanding of the fundamental processes that underlie pregnancy. My research is aimed at saving babies lives and reducing the long-term burdens (health, emotional and economic) of major perinatal conditions. I am uniquely placed to carry out this research, using the research tools I have developed to deliver real outcomes that will change clinical practice
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.
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
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.
Improving The Long-term Quality Of Life For Preterm Children

Summary
My vision is to improve the long-term quality of life of preterm children (<37 weeks’ gestation), with a specific focus on those born very preterm (VP; <32 weeks’ gestation). To achieve this goal my research has two broad and related aims: 1) Determine the neurological and socio-environmental mechanisms leading to impairments in preterm children; and 2) Develop and assess the efficacy of perinatal and early intervention programs for preterm children.

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
Each year approximately 24,000 Australian children are born too early. A new international study led by Western Australian researchers is studying the role that genetics play in preterm birth. This study will evaluate the genomes of 10,000 women of which 2,000 come from Western Australia. It is anticipated that this study will advance our knowledge about the genetic basis of preterm birth and assist in providing customised clinical care to those at highest risk.
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.
