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
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
A Randomised Controlled Trial Of Enhanced Parenting Capacity To Improve Developmental Outcomes In Preterm Infants

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? How can I ensure I get enough iodine? This project will develop new methods for evaluating the effects of nutrients and to pass that information on to health practitioners so that Australian mothers will be in no doubt about the best diet for them and their chil ....Good nutrition is a vital element in a healthy start to life.

Summary
Influenza is a serious illness for young babies. Currently there are no vaccines that can be given to babies under 6 months of age to protect them from infection. This study aims to determine whether influenza vaccine given in pregnancy can prevent infection in babies up to 6 months of age.
Immunomodulatory Effects Of Omega-3 Polyunsaturated Fatty Acids : Role In Allergy Prevention In Infancy

Summary
The dramatic increase in asthma and allergic disease over the last 20-30 years has highlighted the urgent need to identify associated environmental changes that may also be logical targets for disease prevention. Although this is likely to be multifactorial, one significant change during this period has been a progressive decline in the intake of dietary anti-inflammatory n-3 polyunsaturated fats (PUFA) in Western diets, with a corresponding increase in n-6 PUFA fatty acids. We recently showed f ....The dramatic increase in asthma and allergic disease over the last 20-30 years has highlighted the urgent need to identify associated environmental changes that may also be logical targets for disease prevention. Although this is likely to be multifactorial, one significant change during this period has been a progressive decline in the intake of dietary anti-inflammatory n-3 polyunsaturated fats (PUFA) in Western diets, with a corresponding increase in n-6 PUFA fatty acids. We recently showed for the first time that n-3 PUFA may have more significant effects in very early life before immune responses are fully established. We confirmed that maternal fish oil supplementation (n-40) resulted in significantly higher n-3 PUFA levels in newborns (compared to those with no supplements, n-43), and this was related to reduced immune responses to allergens (such as house dust mite, cat and egg). These observations suggest that n-3 PUFA can modify early immune development. Although this previous study was designed to assess immune outcomes (rather than clinical outcomes) we collected preliminary clinical data for the purposes of this application. We observed a consistent trend for less allergic symptoms and sensitisation in the supplementation group. These observations clearly warrant this proposed study to confirm these clinical effects, and to assess the mechanisms of action in considerably more detail. In this proposed study we will compare the effects of fish oil (n-165) or placebo (n-165) in early infancy (from 0-6 months of age). This much larger population will allow us to determine if increasing dietary n-3 PUFA is a way of reducing the chance of allergy in families where there is a high genetic risk. Approximately 40% of infants in Australia will go on to develop asthma or allergies. Strategies such as this that reduce the risk (even slightly) or the severity of disease expression could have enormous impact in this global context at relatively little cost.Read moreRead less

Summary
Problems around birth are common and can have long-term implications, including into adulthood. Our goal is to improve health outcomes for all newborn babies and their families by determining factors that enhance outcome and assessing the benefits and consequences of new treatments for mothers and babies. We are world leaders in this field and are dedicated to training the next generation of health professionals in the care of newborn babies, in Australia and the rest of the world.
DHA For The Improvement Of Neurodevelopmental Outcome In Preterm Infants: The DINO Trial

Summary
The incidence of neurological problems that occur in children born prematurely is higher than for those born at term. The earlier that a baby is born, the greater chance it has of having some developmental delay and general inability to cope at school. This has implications for the child, the families and the health system. One of the many dietary factors implicated in the development of neural abilities in premature infants is an omega-3 fatty acid called DHA.

The earlier that a baby is born, the greater chance it has of having some developmental delay and general inability to cope at school. This has implications for the child, the families and the health system. One of the many dietary factors implicated in the development of neural abilities in premature infants is an omega-3 fatty acid called DHA. This compound is present in breast milk and most preterm formulas and is found in high concentrations in the brain and retina. In the last third of pregnancy the developing baby would normally accumulate DHA at a rapid rate. So it seems reasonable to assume that a baby outside the mother, that is born premature, would also need to accumulate DHA at this same rate. The problem is that none of the milks currently given to premature infants have DHA in high enough concentration to supply this amount of DHA to the baby. For example, breast milk and preterm formulas contain only a third of the DHA required. In order to provide this amount for the premature infant, breast milk containing DHA at about 1% of the total fat is required. Fortunately the level of DHA in breast milk can be increased to this level by supplementing the mothers diet with fish or olis like tuna oil. This study hopes to show that premature babies who receive DHA in amounts similar to that supplied in the womb will develop better than babies who receive low amounts of DHA.Read moreRead less
