Summary
There is substantial epidemiological evidence that formula fed infants are more susceptible than breast fed infants to auto-immune diseases later in life. However direct evidence is lacking and the mechanism is not understood. We aim to provide direct experimental evidence to test the hypothesis that maternal milk regulates infant immune responses by providing the factors that modulates antigen presentation and priming in the neonatal gut.

However direct evidence is lacking and the mechanism is not understood. We aim to provide direct experimental evidence to test the hypothesis that maternal milk regulates infant immune responses by providing the factors that modulates antigen presentation and priming in the neonatal gut. The significance of the study lies in the absence of these regulatory factors in infant formula. The results will allow more fully informed decisions regarding breast feeding, and may lead to the development of infant formula that modulate immune responses in a manner analogous to natural maternal milk.Read moreRead less
Transcriptional Regulation Of Gene Expression: Dietary Sialic Acid Interaction In Brain Cognitive Development

Summary
In 2004, 8.2% of Australian live births were preterm with poor long-term cognitive outcomes. Sialic acid (SA), a key component of both human milk oligosaccharides and neural tissues, plays a role in neuronal development. This study will examine the mechanisms of how dietary SA or active learning interacts with genes during brain development. It will benefit the neonatal care of all children, particularly those born premature and ultimately, the quality of life of many Australians.

Summary
Sub-optimal nutrition during critical periods of brain growth has persistent effects on the human brain. Premature infants are especially vulnerable because brain growth reaches its peak at 26 weeks gestation and remains high throughout the first year of life. Those fed human milk in the first month after birth have been shown to have a significant intellectual advantage compared with infants fed standard infant formulas. While the n-3 fatty acids such as DHA are thought to be important, other c ....Sub-optimal nutrition during critical periods of brain growth has persistent effects on the human brain. Premature infants are especially vulnerable because brain growth reaches its peak at 26 weeks gestation and remains high throughout the first year of life. Those fed human milk in the first month after birth have been shown to have a significant intellectual advantage compared with infants fed standard infant formulas. While the n-3 fatty acids such as DHA are thought to be important, other components of human milk may be of greater significance for brain growth. Our interest is in a sugar compound called sialic acid. It occurs in remarkably large amounts in human milk (up to 1g-L) but is present in only small quantities in infant formulas. Sialic acid is an important structural and functional component of brain cells. It is directly involved in nerve cell transmission, memory formation and cell-to-cell communication. During peak brain growth, young infants, especially pre-term ones, are unlikely to be able to synthesise sufficient sialic acid to meet their needs. At these times, they rely on human milk and infant formulas to supply the necessary building blocks. If their diet is a poor source of sialic acid, however, there may be lasting consequences for intellectual development. This research project addresses several questions. 1. Does oral sialic acid supplementation over the first few weeks of life increase both brain sialic acid levels as well as learning behaviour? 2. Is there any dose-response relationship - is more better? 3. Does supplementation influence the expression of genes encoding key enzymes in the brain? 4. Does dietary supplementation affect the activity of the liver enzyme involved in synthesis of sialic acid? If our findings can be extrapolated to human infants, they will have implications for the etiology of all types of cognitive and behavioural defects in children, including learning difficulties and attention deficit disorder.Read moreRead less
We are an international team committed to clinical trials to improve survival without disability in newborn babies. We plan a randomised trial to confirm if bovine lactoferrin, an inexpensive dairy protein, reduces death or major morbidity and increases total breast milk intake in 1,500 very low birthweight babies in neonatal intensive care units
Best Fed: Implementing Evidence Based Clinical Practice Guidelines To Improve Breast Milk Use And The Feeding Management Of Infants Born

Summary
Breast milk is the best food for babies born prematurely. There are challenges for women in providing breast milk and challenges for clinicians in managing the feeds of preterm babies, including when to start feeds and how quickly to progress. Sometimes research evidence doesn’t translate into practice and in this project I will support clinicians to implement the best evidence so that more preterm babies are receiving breast milk on discharge home.
A Randomised Controlled Trial Of Enhanced Parenting Capacity To Improve Developmental Outcomes In Preterm Infants

Funding Amount

Summary
In Australia there are 2, 600 very preterm survivors each year. 50% will have education/behavioural difficulties and 10% major disability. We aim to optimise the development of infants born very preterm through a tailored Positive Parenting Program. We predict reductions in child behavioural and emotional problems at 2 years corrected age.
Good nutrition is a vital element in a healthy start to life. Determining the correct foods to ensure that pregnant women meet both their needs as well as those of their new baby can be very confusing. Do I need to take iron supplements?

Docosahexaenoic Acid For The Reduction Of Bronchopulomonary Dysplasia In Preterm Infants Born At Less Than 29 Weeks Gestational Age: A Randomised Controlled Trial

Summary
A major challenge in the care of very preterm babies, is dealing with the fact that the baby has very immature lungs. They are prone to an inflammatory condition known as BPD (broncho-pulmonary dysplasia) that prevents an infant from breathing, much like asthma in older children. This can result in poor health outcomes for life. Our study will test the effect of the omega 3 fat known as DHA in reducing this inflammation in the lung and result in better outcomes for the baby.
