Summary
Aboriginal children in the Top End of Australia have high rates of hospital admission for diarrhoea and malnutrition. We have discovered that underlying small intestinal damage in these children is an important contributor to the high complication rates and longer lengths of stay in hospital compared to non-Aboriginal children.

We have discovered that underlying small intestinal damage in these children is an important contributor to the high complication rates and longer lengths of stay in hospital compared to non-Aboriginal children. This research proposes to continue our work on small intestinal damage by using two non-invasive tests of gut function, namely a sugar absorption test and novel breath test. The sugar permeability test involves the children drinking a solution of the two sugars lactulose and rhamnose, and measuring their absorption into the blood 90 minutes later using a sophisticated measuring instrument called HPLC, which can measure minuscule amounts of sugars and is set up at Royal Darwin Hospital. The breath test involves children drinking another sugar solution with a special non-radioactive marker called a stable isotope of carbon, and measuring changes in the amount of this marker in carbon dioxide from the breath at timed periods after drinking the sugar solution. The breath is analysed in Adelaide using another sophisticated instrument. These tests are being used to measure abnormal sugar absorption due to intestinal damage, which is particularly common in Aboriginal children during the weaning period of 4-18 months. Our hypothesis is that treatment with 'healthy germs' (probiotics) like those in certain yoghourts will colonise the gut, stimulate immunity and reduce the presence of 'nasty germs' (pathogenic bacteria) in the intestines of Aboriginal children which contribute to the need for their hospitalisation with diarrhoea and malnutrition. If this hypothesis is correct, then this research will provide the best kind of evidence for reducing the need for hospital treatment by treating all cases of diarrhoea with these probiotics and possibly even decreasing the gut damage of children in the weaning period by including probiotics in their dietsRead moreRead less

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

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

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

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.

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.

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.

Summary
Currently, premature infants are born without the normal immune defenses of infants born at the correct time because the protective factors that normally pass from the mother to the baby during the last few months of pregnancy have not had time to do so. In addition the tiny premature infants are at risk because they need the expertise of intensive care and are therefore separated from their parents and their parents' organisms which healthy term infants normally pick up from the birth canal and ....Currently, premature infants are born without the normal immune defenses of infants born at the correct time because the protective factors that normally pass from the mother to the baby during the last few months of pregnancy have not had time to do so. In addition the tiny premature infants are at risk because they need the expertise of intensive care and are therefore separated from their parents and their parents' organisms which healthy term infants normally pick up from the birth canal and their parents skin. The infants commonly develop infections from organisms living on their skin surfaces or inside their lungs, stomach or bowels. The babies are living in a hospital environment which they need to survive, but they may pick up particularly unhealthy organisms (pathogens) that produce toxins, which are difficult to treat even with antibiotics. These infections are so severe that one-fifth of the babies die, even in Australia where facilities for premature infants are excellent. Two recent studies overseas have shown that giving premature babies special preparations of certain probiotic organisms decreases the chance of babie developing infections. Probiotics are organisms that have health benefits. Probiotics tighten the spaces between cells to stop bacteria getting into the body, produce substances that kill other bacteria and promote the production of immunoglobulin A by the baby's own cells. Immunoglobulin A is a substance that lines the bowel wall and protects the baby from invasion by bacteria. This study will offer this probiotic product to very premature babies in a trial to see if it produces additional benefits for our babies in Victoria. Around five hundred babies will be given the product and five hundred will be given the placebo ( a harmless inert product which will look just like the real probiotic). Currently 23% of our babies get the serious infections and this study is powerful enough to see if we can reduce the number by one third.Read moreRead less
