Summary
Children undergoing open heart surgery on a heart lung machine can experience serious side effects from the exposure to the artificial circulation during surgery and may have either prolonged need for life support in intensive care or even may suffer from long term complications. In this study we investigate the use of a new approach using nitric oxide, a anti-inflammatory gas, during surgery to reduce these side effects.

Summary
The primary aim of this project is to identify techniques for resuscitating premature babies that cause little or no damage to their lungs. We also want to identify factors that enhance the clearance of liquid from the lungs so air can easily enter to deliver oxygen and remove carbon dioxide at birth. About 1% of babies are born very prematurely and many develop respiratory distress syndrome (RDS). This is the major cause of illness and death in infants born at less than 32 weeks' gestation.

We also want to identify factors that enhance the clearance of liquid from the lungs so air can easily enter to deliver oxygen and remove carbon dioxide at birth. About 1% of babies are born very prematurely and many develop respiratory distress syndrome (RDS). This is the major cause of illness and death in infants born at less than 32 weeks' gestation. Most of the survivors required assisted ventilation during their first weeks of life. In 1995, 2381 premature infants were ventilated in Australia and New Zealand, requiring 36,407 days of ventilator care. Thus, this is a serious condition with a high financial and social cost. It is known that RDS is caused by damage to the very immature lung which starts an inflammatory reaction. We don't know what triggers the damage and inflammation but believe that the way babies are resuscitated may damage the lungs. Currently, babies are resuscitated with a resuscitation bag squeezed by hand, with 100% oxygen. There is no pressure to stop the lungs collapsing during expiration. As the volume of gas delivered with each breath is not measured, it is possible that the volumes are too large and damage the lungs. This project will investigate whether less damage occurs to the lungs of preterm lambs when resuscitation uses a modern neonatal ventilator where each inflation is limited to a known volume. A small distending pressure will be used to stop the lungs collapsing during expiration. We will also investigate factors that enhance the clearance of liquid from the lungs after the initiation of breathing. The failure to clear lung liquid greatly limits the ability of babies to breathe and exposes those parts of the lung that are cleared to a much greater risk of injury. The results of this study will be directly applicable to the treatment and care of prematurely born babies.Read moreRead less
Characterization Of Cellular Inflammatory Responses Underlying Acute Viral Bronchiolitis In Infants

Funding Amount
$583,224.00
Summary
This project seeks to characterize the inflammatory mechanisms triggered during severe respiratory virus infections that result in hospitalization of infants. These are associated with later development of asthma. We aim to identify new molecular targets for anti-inflammatory drug development, with the long term goals of improving treatment for acute disease, and prevention of subsequent asthma.
Can Pentoxifylline Improve Long-term Outcomes In Preterm Infants With Late-onset Sepsis Or Necrotizing Enterocolitis – A Pragmatic, Randomized, Controlled Trial
Funder

Funding Amount
$2,901,130.00
Summary
Very preterm infants are at high risk of death and disability. Brain injury is often the result of inflammation caused by infection or bowel disease. To date, there is no treatment to reduce the harmful effects of inflammation. Pentoxifylline reduces inflammation and is a promising, safe and inexpensive treatment option for preterm infants. This study will determine whether Pentoxifylline in addition to antibiotics improves survival without disability in preterm infants.
Contribution Of Systemic Inflammatory Response To Brain Injury In Growth Restricted Newborns

Funding Amount
$363,388.00
Summary
Growth restriction during pregnancy can damage the baby’s brain and result in poor outcomes such as learning and attention difficulties and cerebral palsy. Currently there is no treatment available to prevent brain injury in these babies. This study will explore the role of inflammation and brain injury in the growth restricted baby. We will also examine whether a readily available and safe anti-inflammatory treatment can reduce or prevent brain injury following growth restriction.
Early Origins Study Of Cystic Fibrosis-related Diabetes

Funding Amount
$128,188.00
Summary
Cystic Fibrosis is a genetic condition that causes recurrent lung infections and early death. Some patients also develop diabetes which causes a more rapid decline. Many young children with CF have “pre-diabetes” but guidelines do not recommend screening high glucose in this group. In order to intervene early, this study aims to determine if “pre-diabetes” in very young children with Cystic Fibrosis causes poorer growth, lung function or an increase in bacterial infections to.
Understanding And Improving Treatment Of Premature Infants To Improve Long Term Outcomes

Funding Amount
$638,517.00
Summary
The last 2 decades heralded many important advances in the care of preterm infants but important gaps in our knowledge remain. Studies undertaken in the preclinical and clinical settings during this Fellowship will enhance understanding of the complex nature of disease in preterm infants. Further, we will develop and evaluate new treatments that enhance growth and development of the premature baby to optimise their long term intellectual, physical, emotional and social outcomes.

The doubling in incidence of type 1 diabetes in children over the last 20 years may be explained by our modern environment, including excessive weight gain in pregnancy and early life, inadequate dietary omega- 3 fatty acids or vitamin D, or viral infections.

Funding Amount

Summary
Type 1 diabetes (T1D) is an autoimmune disorder that results in the destruction of the pancreatic beta cells. The overall aim of the CRE is to elucidate the gene-environment interactions and modifiable environmental exposures that are driving the development of islet autoimmunity and progression to T1D. The CRE will unify and add value to new and established collaborations with multi-disciplinary input from genomics, bioinformatics and systems biology into the investigation of T1D.

Summary
Why airway inflammation becomes chronic so early in life for people with cystic fibrosis (CF) is unclear. This project will use the latest techniques to characterise immune cells found in airways of infants with CF and model in the laboratory how immune cells react to the CF airway. We will challenge CF airway cells with different bugs that can infect the lung, then see if the responses by CF airway cells can change the normal response of immune cells, triggering chronic disease.
