Summary
Our research aims to optimise protection for infants and children against serious infectious diseases causing death and disability, such as whooping cough, influenza and meningococcal disease. We will establish the safety and effectiveness of vaccines to improve protection against these infections. Our community research will determine the best ways to improve uptake of immunisation in children and in pregnant women to provide the best protection for infants and mothers.

Summary
Addressing the diabetes epidemic in the Indigenous Australian population requires early intervention. Early life is critical for long term risk of chronic disease but little is known regarding effective interventions, particularly for follow-up of children after a pregnancy complicated by diabetes. The project examines growth, body composition, and risk of developmental issues in children of mothers with and without diabetes in pregnancy, exploring risk factors for later chronic disease.
Previous research has shown that SIDS victims have a number of subtle abnormalities that set them apart from the normal population. These include the occurrence of upper airway obstruction in sleep, a reduced ability to awaken from sleep and abnormalities of the automatic control of heart rate and blood pressure in sleep. These body functions are controlled by a component of the brain called the autonomic nervous system which controls the heart and other internal functions by means of nerves cal ....Previous research has shown that SIDS victims have a number of subtle abnormalities that set them apart from the normal population. These include the occurrence of upper airway obstruction in sleep, a reduced ability to awaken from sleep and abnormalities of the automatic control of heart rate and blood pressure in sleep. These body functions are controlled by a component of the brain called the autonomic nervous system which controls the heart and other internal functions by means of nerves called the parasymmpathetic and sympathetic systems. The purpose of this project is to undertake studies of the autonomic system in normal infants and in those infants who are considered to be at risk for SIDS. As SIDS occurs almost exclusively in sleep it is important to study the infant?s heart rate and blood pressure responses to various challenges whilst asleep. All infants (both controls and subjects) enrolled in the protocol will therefore undergo overnight sleep studies during which their automatic responses to a variety of stimuli will be measured. Once we have established the normal response to these stimuli we can then compare them to the results of the at risk group. If, as we anticipate, there is a difference between our at risk group and the normal controls in automatic function then we will measure some of the stress hormones in the body which reflect the function of the autonomic nervous system. If there is a difference in the levels of these hormones between the normal and the at risk groups which correlates with the expected subtle abnormalities in function we may be able to devise an accessible and quantifiable measure for those infants at risk of SIDSRead moreRead less
Factor V Leiden Mutation: A Contributory Factor For Cerebral Palsy?

Summary
Cerebral palsy is the commonest physical disability in childhood. It has a major impact on individuals and families. In a significant proportion of cases, the cause is unknown so further research is essential to define the reasons for this condition, and thereby develop preventative strategies. Two mutations have been identified that predispose carriers to develop blood clots (called thrombosis). These mutations are the Factor V Leiden mutation and the coagulation gene for prothrombin (also know ....Cerebral palsy is the commonest physical disability in childhood. It has a major impact on individuals and families. In a significant proportion of cases, the cause is unknown so further research is essential to define the reasons for this condition, and thereby develop preventative strategies. Two mutations have been identified that predispose carriers to develop blood clots (called thrombosis). These mutations are the Factor V Leiden mutation and the coagulation gene for prothrombin (also known as the G20210A mutation). If blood clots form in, or travel to the brain (embolism), they can obstruct the blood supply causing damage that may result in cerebral palsy in young children. Our research will investigate both mothers of children with cerebral palsy, and the children themselves. The study of the mothers will determine whether those that are carriers of these mutations are at an increased risk of having children with cerebral palsy. Factors that may precipitate the development of blood clots, such as smoking during pregnancy, will be investigated. The children with cerebral palsy will be studied to determine whether they carry the mutations, and if so, whether they have brain scan evidence of previous blood clots. Children will be tested for the mutation using the blood spot taken routinely early in life. These blood spots are stored on cards (Guthrie cards) and are available for research following parental consent. The mothers will be tested for the mutation by using a saliva sample and will also be interviewed to obtain details of their pregnancies. As a result of this project, useful information will be provided for families and health care providers. It will be established whether these mutations play a role in the genesis of cerebral palsy. In addition, data about possible factors which may increase the risk in carrier mothers, such as smoking, will be provided.Read moreRead less
