Summary
This project is developing a factor to enhance organ maturation and repair that may provide a new therapy for premature babies and fetuses with birth defects. This exciting new finding allows for the development of treatments of underdeveloped organs, in particular the lungs of premature and growth restricted babies. We are also trialing this factor in unborn babies with defects to the kidneys and lungs of which there is currently no cure.
Innate Immunity And Neonatal Infections In Preterm Infants

Summary
In Australia, over 20,000 babies are born prematurely every year. Over 430 of these babies will die in the neonatal period, while another 15,000 will suffer neonatal and/or lifelong morbidity. Forty seven percent of these neonatal deaths will be due to neonatal infections. This research aims to prevent such devastating loss through characterising aberrant innate immune responses associated with the development of neonatal infection and identifying factors that lead to this outcome.
Optimising Non-invasive Ventilation At Birth For Preterm Infants

Summary
Infants born very premature require respiratory support at birth to make the transition to newborn life. As these infants are very immature and prone to injury, modern respiratory care strategies utilise the least invasive approaches mainly applied using a facemask. However, we have discovered that the larynx is closed at birth and thereby prevents air from entering the lung. This application is focussed on optimising the efficiency of facemask ventilation at birth and stimulating breathing.

Summary
Exposure of babies to infection or inflammation before birth is common and is associated with preterm delivery and illness in newborns. The biggest problem for these babies is lung disease due to inflammation of the lungs before birth and/or in response to lung injury after birth. There is no treatment for the underlying inflammation and no way to prevent or treat the lung disease that it causes. This project will investigate a new stem-cell based treatment for lung inflammation that may prevent ....Exposure of babies to infection or inflammation before birth is common and is associated with preterm delivery and illness in newborns.

The exposure of infants to adverse events both before and after birth can cause death or permanent disability (eg cerebral palsy) for the infant. Our primary research objective is to minimize the impact and improve outcomes for infants exposed to adverse events before and/or after birth. We will use a multi-disciplinary approach that aims to understand the science and to develop new treatments, thereby representing true “bench to bedside” research.
Asking QUestions About Alcohol In Pregnancy (AQUA): Longitudinal Cohort Study Of The Effects Of Low And Moderate Doses Of Alcohol Exposure On The Fetus

Summary
National alcohol guidelines advise women to have no alcohol in pregnancy. However, many find they are unexpectedly pregnant and have been drinking, leading to considerable anxiety. While evidence is clear that heavy drinking is bad for the unborn baby, no-one knows for sure if low or even moderate levels of alcohol in pregnancy are harmful. We will study this important public health problem, following a group of pregnant women through their pregnancy and until their child is two years.
Does Caffeine Affect The Development Of The Very Immature Brain: Dose Response Relationship?

Summary
Premature birth is a major health problem worldwide. Preterm babies often develop apnoea of prematurity (AOP), which is commonly treated with caffeine. Trials indicate that preterm babies treated with low dose caffeine have less neurodevelopmental disabilities at 18 months. Higher doses of caffeine are often needed to reduce AOP but the risk of this is unknown. We will study the short and long-term effects of increasing doses of caffeine on the developing brain in a long-gestation species.

Summary
In the lung, gas exchange takes place in small terminal airsacs called alveoli. The internal surface of the alveoli are lined with 2 types of specialist cells, the type-I and type-II cells. Both cells are essential for the normal functioning of the lung; type-I cells provide a thin barrier for the gas exchange, whereas type-II cells produce the surface-active material, surfactant. In order to survive after birth, the lungs of the newborn must have appropriate numbers of each of these cell types. ....In the lung, gas exchange takes place in small terminal airsacs called alveoli. The internal surface of the alveoli are lined with 2 types of specialist cells, the type-I and type-II cells. Both cells are essential for the normal functioning of the lung; type-I cells provide a thin barrier for the gas exchange, whereas type-II cells produce the surface-active material, surfactant. In order to survive after birth, the lungs of the newborn must have appropriate numbers of each of these cell types. However, babies that are born very prematurely have few, if any, mature cells as most are non-specialised cells that possess none of the characteristics of mature type-I and type-II cells. Therefore, the lungs of very preterm babies have low levels of surfactant, are prone to injury and infection and are not efficient in the exchange of oxygen and carbon dioxide. As such, these infants are at high risk of developing chronic lung disease which is a serious debilitating disease that has long term health implications. We believe that the non-specialised cells are more prone to injury and cell death than mature cells which makes the very premature infant more susceptible to the development of chronic lung disease. As the survival and respiratory health of these infants depends upon most type-I and type-II cells maturing after birth, it is critical to understand the factors that regulate their maturation. This information will allow the development of treatments that can enhance the maturation of these cell types. This application is focused towards understanding the factors that control maturation of type-I and type-II cells, as well as the role of the non-specialised cells in the development of chronic lung disease in babies that are born very prematurely.Read moreRead less
