Summary
This research will develop a spatial simulation model to predict the spread of pandemic influenza within Australia. The resulting software program will be readily usable by disease managers, both during and prior to an outbreak, to predict the effect of various containment measures on the size, rate and location of disease spread, through a city, state or the nation.

The resulting software program will be readily usable by disease managers, both during and prior to an outbreak, to predict the effect of various containment measures on the size, rate and location of disease spread, through a city, state or the nation. Deployed in _real time� after an outbreak has started in Australia, it will be used to predict infection spread and the containment effect of a range of interventions. The model would use data obtained during initial stages of the outbreak to refine the model, so allowing accuracy in daily spread prediction; similar use of spatial models occurred during the 2001 Foot and Mouth Disease (FMD) outbreak in the UK. In a pre-pandemic period the simulation model will be available to predict the containment effect of a range of response measures, such as travel restrictions, workplace and school closures, vaccination and antiviral usage. Specifically, this project will apply the simulation model to determine optimal use of limited resources such as the _when and where� targeting of antiviral drugs and initial supplies of vaccine.Read moreRead less

Summary
The aim of this study is to help us prepare for a pandemic of influenza by comparing how effective the various available control strategies are at reducing transmission of the disease. The available control interventions include: reducing the number of close contacts we make with others, isolating cases after they are diagnosed, closing schools, quarantining households, quarantining individuals who are known to have been exposed to a case, and using antiviral drugs treat and protect people at ri ....The aim of this study is to help us prepare for a pandemic of influenza by comparing how effective the various available control strategies are at reducing transmission of the disease. The available control interventions include: reducing the number of close contacts we make with others, isolating cases after they are diagnosed, closing schools, quarantining households, quarantining individuals who are known to have been exposed to a case, and using antiviral drugs treat and protect people at risk of being infected. We will compare these control measures by taking due account of the ability and resources available for these interventions, and with regard to the need to maintain essential services. The comparisons will be made using mathematical models that describe the transmission of the infection. All available data and advice from experts will be used to ensure that realistic models are used for the comparisons. We will also use the models to determine the best use of the limited antiviral drugs available, until a vaccine becomes available. We will consider how the control strategy should be changed if a strain develops that is resistant to the antiviral drugs. In addition, we will determine what data need to be collected during the early stages of a pandemic to help us to determine the best use of the antiviral drugs, the best use of a new vaccine and to check on the development of resistance to the antiviral drugs.Read moreRead less
Modelling The Biology And Transmission Of Influenza Virus - Learning From 1918-19 And Other Outbreaks

Summary
In preparing for a future pandemic of influenza, it is important to learn as much as possible from what happened in the past, particularly from the devastating pandemic of 1918-19. This project will collate detailed information about the spread of influenza in past outbreaks and create a publicly accessible data-base.

This project will collate detailed information about the spread of influenza in past outbreaks and create a publicly accessible data-base. Mathematical methods will be used to analyse historic and contemporary data, so as to provide better understanding of the spread of influenza, and of the likely effects of social and medical measures for its control. An important theme of the project is to consolidate our knowledge about how past exposure to non-pandemic influenza could provide short-lived protection against any new pandemic, and to explore the implications of this for prevention today. Another theme is to explore the severity of influenza during pandemics, and to identify social and medical factors that might reduce the dose of virus transmitted, or otherwise reduce the severity of infection. The insights from the modeling will also help to identify gaps in knowledge and understanding about the basic biology of influenza, stimulate new research to fill those gaps, and thus offer the prospect of more effective vaccines and treatments for the future control of influenza.Read moreRead less

ENGAGE will do this through the integration of very large datasets already available from a substantial number of large and well-characterised samples. The resulting ENGAGE resource will represent a research investment >€100M (>AU$160M) and provide unprecedented power to discover disease and trait susceptibility genes. QIMR will contribute 12,000 twins for ENGAGE joint analyses and provide analytical expertise in the analysis of disease and genetic data related to lifestyle and metabolic traits, with particular emphasis on cardiovascular disease, type 2 diabetes and migraine risk factors. Our laboratory will also perform vital further genetic studies to establish the causal relationship between the genetic variants concerned and the traits of interest. Most importantly, our direct participation will allow the translation of these findings into the Australian population and clinical arena.Read moreRead less

Apathy is the state of loss of motivation and emotional withdrawal that occurs in a high proportion of patients with Alzheimer’s disease. These patients require more management and support, given their reliance on others to schedule their activities and initiate behaviours even when they are still capable of performing the activities. In spite of the high frequency of apathy in dementia and the high potential of negative effects on patients and caregivers, little is known about the cause of this phenomenon, its potential influence upon the long-term progression of Alzheimer’s disease, and on its impact upon caregivers’ emotional well-being. The main aim of our proposal is to examine the mechanism, clinical relevance and impact of apathy in Alzheimer’s disease. More specifically, we will determine whether apathy predicts more severe depression, increasing motor problems, and a faster progression of cognitive and functional problems. Using state-of-the-art neuroimaging techniques we will examine the association between apathy and abnormalities in specific brain regions. Finally, we will examine whether caregivers of patients with apathy have relatively more severe emotional problems, a higher care giving burden and poor quality of life.Read moreRead less
