Summary
Intrauterine growth restriction (IUGR) is a serious complication of pregnancy and occurs when fetal growth is abnormal, resulting in a fetus that is smaller than it should be for its given gestational age. IUGR babies are at much greater risk of many short and long-term adverse outcomes. This study investigates the role that adverse cardiovascular development plays in the progression of lung, heart and brain disease in preterm IUGR newborns.
Does Maladaptive Remodelling Of The Heart And Vasculature In Response To Preterm Birth Lead To Long-term Cardiovascular Risk?

Summary
Being born prematurely is linked to the development of high blood pressure (a major risk factor for cardiovascular disease) later in life. In this project we will examine whether injury to the cells lining the cardiovascular system and/or structural changes in the wall of the arteries and the heart, as a result of being born early, lead to an elevation in blood pressure and heart dysfunction in adulthood.
Understanding The Causes Of Childhood Congenital Anomalies Of The Kidney And Urinary Tract

Summary
Congenital anomalies of the kidney and urinary tract (CAKUT) is a common cause of renal failure in children. The majority of patients with CAKUT do not know the underlying cause of their renal anomalies. In this proposal we will characterise the developmental events that are perturbed in three mouse models of CAKUT and identify the causal gene responsible in each mouse model. We will translate this information to the clinic by screening patients with CAKUT for mutations in these newly identified ....Congenital anomalies of the kidney and urinary tract (CAKUT) is a common cause of renal failure in children.

Being Born Small Is Not Good For The Heart:early Detection Of Cardiovascular Risk

Summary
Intra uterine growth restriction(IUGR) is linked to adult onset of cardiovascular disease. However, little is known about the mechanism(s) which underlie this link or which babies are most at risk. This study aims to assess cardiovascular function in infants and children who were growth restricted. Early identification of cardiovascular dysfunction may aid in new opportunities for monitoring and therapeutic targets to ultimately reduce later onset of cardiovascular morbidity in this population.
Understanding White Matter Injury In Term-born Children With Cerebral Palsy

Funding Amount
$193,863.00
Summary
The type of brain injury in cerebral palsy varies. In some children the brain develops abnormally in early pregnancy; others have a stroke or suffer from lack of oxygen around the time of birth. Little is known about the group of children born at term who have damage to the brain’s white matter, a pattern more typical of premature birth. This project will explore brain imaging, potential risk factors, and clinical outcomes for these children to identify possible causes and prevention pathways.
Developmental Changes In Cerebral Oxygenation After Term And Preterm Birth

Summary
Approximately 10% of all births are preterm and the numbers of infants surviving are increasing. We have previously found that infants born preterm have lower blood pressure over the first 6 months after term equivalent age than infants born at term. We will use new technology to examine how preterm birth affects brain oxygenation and how this is altered with gestational age, sleep states and sleeping position, to provide insights into their increased risk for SIDS.
Mechanisms Contributing To Long-term Neuronal Loss After Hypoxia-ischemia In The Premature Neonate Brain.

Funding Amount
$432,535.00
Summary
A lack of oxygen (hypoxia) and blood flow to the brain (ischemia) around the time of birth can cause brain injury that perists into adulthood. The burdens on financial, educational and healthcare resources are enormous. We will improve our understanding of what parts of the brain are injured and the mechanisms contributing to on-going brain injury after hypoxia-ischemia.This is important to devise treatments and to provide a healthy start to life for neonates.
Executive Dysfunction And Brain Development In Very Preterm 13-year-olds - A Longitudinal MRI Study.

Summary
An area of concern for very preterm children is executive function (i.e. skills used for problem solving), which is related to educational problems, behavioural issues and social difficulties. In very preterm children this study will 1) determine if executive function problems remain stable, worsen, or improve with age; 2) look for markers for these problems from infant brain scans; and 3) examine how executive function difficulties are related to brain re-organisation.

Summary
Approximately 4 out of every 1000 babies suffer severe perinatal asphyxia (a period of a shortage of oxygen) during the birth process which carries with it a high risk of brain damage or death. Those babies surviving with a severe disability cost Australia $500,000,000 per annum in lifelong costs. With currently available methods, the presence of asphyxia is difficult to detect and hence prevention is often not possible.

Those babies surviving with a severe disability cost Australia $500,000,000 per annum in lifelong costs. With currently available methods, the presence of asphyxia is difficult to detect and hence prevention is often not possible. At present, there are no effective medications to treat asphyxia-related brain damage in babies. This study brings together a multi-disciplinary team driven by the clinical need to develop suitable strategies for neuroprotection in the developing brain. We will investigate the neuroprotective properties of the clinically relevant factor of acidosis and determine how acidosis influences neuroprotectant drugs. In the future, it is envisaged that this study will lead to rationally-based clinical trials aimed at improving neurodevelopmental outcomes for babies who suffer asphyxia and for infants who are victims of near-drowning or head trauma.Read moreRead less
