Summary
Being born too early is a leading cause of perinatal death and morbidity. This trial seeks to determine whether screening for and treating candidiasis in pregnancy reduces the risk of this serious health problem. The trial will discover whether a simple treatment in pregnancy can reduce preterm birth. If positive, the results will be relevant to the management of every pregnancy.

Summary
Poor growth before birth or intrauterine growth restriction (IUGR), as indicated by being light, short or thin for stage of pregnancy, greatly increases the risk of illness and death before and after birth and in infancy. IUGR has increased risks of asphyxia, poor glucose control, hypothermia, respiratory difficulties, neurological problems and poor immune function, many of which persist. IUGR is one of the most common clinical problems in obstetrics and neonatology, with ~6% of infants born IUG ....Poor growth before birth or intrauterine growth restriction (IUGR), as indicated by being light, short or thin for stage of pregnancy, greatly increases the risk of illness and death before and after birth and in infancy. IUGR has increased risks of asphyxia, poor glucose control, hypothermia, respiratory difficulties, neurological problems and poor immune function, many of which persist. IUGR is one of the most common clinical problems in obstetrics and neonatology, with ~6% of infants born IUGR in Australia in non-Aboriginal communities and between 7 to 17% in Aboriginal communities. Despite these adverse consequences for health of the individual throughout life, we do not currently have any effective therapies to treat IUGR. Small infants are mostly a result of an inadequate supply of oxygen and nutrients before birth, due to an impaired capacity of the mother to acquire these for the placenta to deliver them to the growing fetus or due to poor functioning of the placenta itself. This intrauterine malnutrition not only slows growth, but impairs the development of a range of body functions leading to the increased risk of illness and death in IUGR. Therapies to be used before birth to treat IUGR need to either restore supply of oxygen and nutrients or to promote growth and functional development. We have discovered that administration of a major growth promoting hormone, insulin-like growth factor-I (IGF-I), to the IUGR fetus, which has low levels of IGF-I, increases its growth. This project will therefore determine if directly giving this hormone in the IUGR fetus will restore development as well as growth before birth, improving function and hence survival and health after birth. If successful, the first effective approach to the antenatal treatment of IUGR will have been identified and would provide the essential knowledge for the design of a range of therapies to best restore the abundance of IGF within the IUGR fetus to improve perinatal and later outcomes.Read moreRead less
Inter-hospital Variations In Outcomes Of Very Preterm Infants Admitted To Neonatal Intensive Care Units

Summary
Most babies who are born very preterm (less than 32 weeks' gestation; ie more than 2 months early) are admitted to a neonatal intensive care unit (NICU). These babies stay in hospital for 2 to 4 months and need lots of care (using vast amounts of the available health resources). When compared to babies born at term, these very preterm babies are much more likely to die or to suffer from a range of poor outcomes that impact on their long-term development and quality of life.

These babies stay in hospital for 2 to 4 months and need lots of care (using vast amounts of the available health resources). When compared to babies born at term, these very preterm babies are much more likely to die or to suffer from a range of poor outcomes that impact on their long-term development and quality of life. The Australian and New Zealand Neonatal Network (ANZNN) is a collaboration of clinical staff in all 29 NICUs in the region, whose aim is to improve the care of high-risk newborn infants and their families in Australia and New Zealand through collaborative audit and research. This audit has reported considerable differences in the rates of death and poor outcomes between NICUs. Other networks have reported similar variations. Variations in outcomes could be due to 1) differences in the way the diagnosis is made in each unit, 2) differences in how small or ill the babies are when admitted, or 3) different quality of care in each NICU. We need to take account of the first two possibilities before we can compare NICUs fairly and allow them to work towards achieving the best outcomes for very premature babies. To do this, our project will use advanced statistical techniques to look at the risk factors associated with death and poor outcome in very preterm babies. We will then be able to 'predict' outcomes and see if the differences between NICUs are real or not. If the variation between units is explained by differences in clinical practices, then this has enormous potential for quality improvement within the NICUs and through the development of new policy guidelines for clinical practice. The statistical models developed during this project will be useful for clinicians in other health areas and in other countries.Read moreRead less
Generating And Applying Clinical Research To Improve The Outcomes Of Neonatal Intensive Care

Summary
Birth is a complex process and sometimes babies require help to make the transition to independent life. Professor Peter Davis is conducting research into how best to support this transition. This involves helping the lungs to work efficiently and supporting the changes in circulation of the blood to the brain and to the rest of the body. His work aims to quickly identify babies who need help and then provide better treatments to make sure they have the best chance of a healthy life.
Optimising Early Respiratory Support For Preterm Infants: The HIPSTER Trial

Funding Amount
$696,791.00
Summary
Premature babies who need breathing support are often given ‘nasal continuous positive airway pressure’ (NCPAP) via large nasal prongs. It works well but is uncomfortable. A newer, popular support is ‘high flow’ (HF) which uses smaller nose prongs and may be more comfortable, but HF has not been well studied. The HIPSTER trial will compare these systems in 750 premature babies, at random half will have NCPAP, half will have HF. We will assess whether babies do equally well with each system.
Respiratory failure at birth is a major cause of death and disease in newborn infants. At birth the airways must be cleared of liquid to allow the inhalation of air, but, little is known about the process of lung aeration, because it has not been possible to observe or measure it. We have developed imaging and analytical techniques to observed and measure lung aeration. We will determine ventilation procedures that promote uniform lung aeration and minimise lung injury in ventilated infants.

Summary
Preterm babies are often slower to reach developmental milestones than term babies. Extremely preterm babies spend a long time developing in the neonatal unit, which is suboptimal to the womb. Evidence suggests that open neonatal units are bright and loud and single rooms may be better for neonatal development. However, a recent study found poorer neurodevelopment with single rooms. This study aims to improve outcomes in single rooms through the application of a sound and language intervention.
Defining Regional Lung Mechanics To Improve Lung Protective Ventilation Strategies In Newborn Infants

Summary
Over 3000 newly born infants require mechanical ventilation in Australia every year. The majority are very premature infants. About 30% of ventilated infants develop serious ventilator induced lung injury. Minimising such lung injury with improved techniques of ventilation which can protect the lung from injury will reduce the considerable short and long term health burden of this population.
