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

Summary
This study will provide a comprehensive description of secondary preventative activities for patients with ischaemic heart disease, with the aim of determining those factors that can most contribute to reducing the increased risk of further events which they experience, and thereby reducing the burden of this disease.

Behavioural and psychological symptoms of dementia have been consistently associated with increased patients’ distress, and are considered by caregivers as the most difficult symptoms to manage.

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

New antimalarial drugs are desperately needed. Protein synthesis in Plasmodium falciparum is a validated target for existing drugs and is a promising target for new drugs. This project brings together malaria biologists with chemists and computer scientists to explore this promising field. We will apply modern methods of drug target characterisation to find the most promising enzyme targets involved in protein synthesis and to identify inhibitors as leads for developing antimalarial therapies.

This project brings together malaria biologists with chemists and computer scientists to explore this promising field. We will apply modern methods of drug target characterisation to find the most promising enzyme targets involved in protein synthesis and to identify inhibitors as leads for developing antimalarial therapies. Australian researchers involved in this project will provide expertise in bioinformatic prioritisation of Plasmodium drug targets from the aminoacyl tRNA synthetase family of enzymes. We will use structural modelling and docking experiments to identify promising antimalarial inhibitors, and will optimise assays to assess the effects of these inhibitors. We will also apply modern molecular biology tools to validate these enzymes as anti-malarial drug targets.Read moreRead less

Summary
During the next three decades the number of persons older than 85 years will more than double, and the health care need of this burgeoning population are assuming greater importance. Recent studies suggest that the prevalence of dementia in Australia will increase from 172 000 cases in 2000 to 588 000 in 2050. This rapid increase in number of dementia cases will result in an increasing burden for caregivers, and in financial terms, for the working-age population.

Recent studies suggest that the prevalence of dementia in Australia will increase from 172 000 cases in 2000 to 588 000 in 2050. This rapid increase in number of dementia cases will result in an increasing burden for caregivers, and in financial terms, for the working-age population. One of the main clinical problems suffered by individuals of dementia is psychological and behavioural changes such as poor insight, irritability and apathy. These problems account for a large proportion of medical expenses, predict early institutionalization, and are associated with poor quality of life of caregivers. Unfortunately, little is known about the true frequency of problems of insight in dementia, about their impact upon caregivers, and about how to best diagnose the problems of loss of insight and judgment in this condition. Our study will examine the frequency and clinical correlates of poor insight and judgment in dementia, it will establish whether these problems predict other common behavioural problems of Alzheimer’s disease such as apathy and dangerous behaviours, and will demonstrate the reliability and validity of a specific instrument to measure insight and judgment in dementia. This will facilitate the early recognition and adequate treatment of behavioural problems in patients with dementia; it will improve patients’ quality of life, and will have a positive impact on both caregivers’ psychological well-being and on clinical practice.Read moreRead less

Summary
Palliative care is highly relevant to the care of people with chronic kidney disease (CKD). As the person’s kidneys fail, dialysis or transplant will be required to prolong life. Palliative care is another option should patients choose not to have treatment. The health care team plays an important role in offering and supporting this choice but the planned patient care pathway often does not include palliative care as an option until the patient’s prognosis is very poor.

As the person’s kidneys fail, dialysis or transplant will be required to prolong life. Palliative care is another option should patients choose not to have treatment. The health care team plays an important role in offering and supporting this choice but the planned patient care pathway often does not include palliative care as an option until the patient’s prognosis is very poor. Health professionals’ own beliefs, values and knowledge about palliative care, death and dying, impact upon their decision to offer and support a palliative care option. This research which will be conducted in Northern Tasmania and will explore how palliative care is currently integrated into the care of patients with CKD and the perceptions that health professionals have about palliative care that may influence their decision making. From this information the research team and participating staff will develop the foundational protocols, resources and education and support program needed to introduce a multidisciplinary care pathway that integrates palliative care for all CKD patients.Read moreRead less
