Summary
Babies born prematurely are more likely to experience problems as a result of being born early with males doing worse than females. The mechanisms causing this difference are unknown. The control of blood flow in the placenta and fetus is essential for normal growth and development. This project will investigate the influence of duration of pregnancy, gender, and exposure to antenatal steroids on pathways that control blood flow in the placenta and the newborn in babies born after prematurely.
Metabolism And Neurotoxicity Of Hemin And Hemin-derived Iron

Summary
Stroke is a leading cause of death and disability in industrialised countries. Much of the brain damage that follows a hemorrhagic stroke is attributable to the presence of free iron which mediates oxidative stress in brain cells. This iron originates from hemin, which in turn is derived from the hemoglobin in extravasated blood cells. The fact that iron is freed from hemin in the post-stroke period makes it an attractive therapeutic target. However, remarkably little is known about the metaboli ....Stroke is a leading cause of death and disability in industrialised countries. Much of the brain damage that follows a hemorrhagic stroke is attributable to the presence of free iron which mediates oxidative stress in brain cells. This iron originates from hemin, which in turn is derived from the hemoglobin in extravasated blood cells. The fact that iron is freed from hemin in the post-stroke period makes it an attractive therapeutic target. However, remarkably little is known about the metabolism of hemin by the different types of brain cells. The present project investigates the metabolism and neurotoxicity of hemin in brain cells and will examine the capacity of potential therapeutic agents to protect brain cells from hemin toxicity. The data obtained from this project will advance our understanding of the uptake and metabolism of hemin by the four main types of brain cell, and the factors that are likely to be involved in the neurotoxicity of hemin-derived iron following hemorrhagic stroke. The study will also provide data concerning the relative effectiveness of potential therapeutic agents, and information concerning the cell types, time points and aspects of hemin metabolism that are most effectively targeted by these agents. Such advances will guide the development of therapeutic approaches that are directed at minimising the brain damage which results from hemin-derived iron in humans.Read moreRead less

Summary
The Global Burden of Disease project, a WHO-World Bank-Harvard collaboration, presented an unprecedented picture of global health across the developed and developing world, providing much-needed information for planning health services. Health was measured at the population level, and combined the number of life years lost due to death and disablement to give a total amount of life lost per disorder. One surprise of the project was the importance of mental disorders, accounting for 43% of life y ....The Global Burden of Disease project, a WHO-World Bank-Harvard collaboration, presented an unprecedented picture of global health across the developed and developing world, providing much-needed information for planning health services. Health was measured at the population level, and combined the number of life years lost due to death and disablement to give a total amount of life lost per disorder. One surprise of the project was the importance of mental disorders, accounting for 43% of life years lost due to disability in countries like Australia. Service planning to reduce this burden requires knowledge of cost-effective treatments.This project will trial a method used for combining burden and cost-effectiveness data to design an essential package of services to address the treatment shortfall in mental disorders. This research will assist in our understanding of why burden due to mental disorders persists, and the extent to which current treatment knowledge is able to address this burden within existing budgetary constraints. This will be achieved by: 1) detailing the costs and population outcome of current services in Australia for mental disorders, to determine which disorders are currently adequately treated and which disorders require further intervention, 2) calculating the costs and outcome of best practice interventions from clinical practice guidelines, to understand the extent to which current treatment knowledge can reduce burden due to mental disorders, 3) examining the equity consequences of such a package of ideal interventions, with the understanding that the treatment endpoint is not the same for all disorders. This is a secondary analysis, representing a method for translating existing cost and outcome data for individual treatments into their costs and consequences for health planning at the population level.Read moreRead less
Balance disorders are very common, but particularly in those conditions that involve the brain 'balance centres' are often difficult for doctors to diagnose. When diseases are difficult to diagnose, then recommending helpful treatment is particularly challenging. We will use a group of specialized tests to better understand these balance conditions in order to help patients receive accurate diagnoses and therefore, better treatment.
