Summary
This proposal utilizes a newly invented process (multiplex tandem polymerase chain reaction, MT-PCR) to measure multiple (up to 100) genetic targets (eg RNA or DNA) in one sample. A range of different virus and bacterial genes can be detected, including those which make the influenza virus different (eg H1N1 or H5N1) and allow it to bypass vaccine immunity or resist drug therapy (due to neuraminidase inhibitor resistance). We will simultaneously target infections which are influenza-like (ILI) o ....This proposal utilizes a newly invented process (multiplex tandem polymerase chain reaction, MT-PCR) to measure multiple (up to 100) genetic targets (eg RNA or DNA) in one sample. A range of different virus and bacterial genes can be detected, including those which make the influenza virus different (eg H1N1 or H5N1) and allow it to bypass vaccine immunity or resist drug therapy (due to neuraminidase inhibitor resistance). We will simultaneously target infections which are influenza-like (ILI) or which might make influenza infection worse (eg staphylococcal pneumonia) as well as their resistance genes (eg MRSA). The test is rapid and automated and includes a specimen processing (DNA and RNA extraction) function that is being developed in parallel. We expect to be able to conduct high-throughput screening of multiple samples for a limited number of targets or conduct multiple tests on fewer specimens, simply by adjusting assay configuration. Measurement of the rise and fall in concentrations of influenza virus in infected persons will allow us to understand when they are no longer infectious to others, to predict when they are getting better or worse, and allow us to better understand the pattern of illness in people who are immunized against influenza or on drug therapy, or are in some other special category (eg immune compromise due to organ transplantation). While this will be able to be rolled out by our industry partners in the event of an influenza pandemic, it does not require an outbreak for successful development, and has value well beyond influenza diagnosis.Read moreRead less

Summary
A number of rapid, point-of-care tests are available for the detection of human and avian influenza types, but they vary greatly in sensitivity. In particular, these tests are based on current strains of H5 (avian) influenza, and may be unable to detect variant or pandemic strains, and negative results can give the false impression that patients do not have H5 influenza. We will develop rapid, point-of-care tests based on highly conserved parts of the virus, so that all H5 strains (current and f ....A number of rapid, point-of-care tests are available for the detection of human and avian influenza types, but they vary greatly in sensitivity. In particular, these tests are based on current strains of H5 (avian) influenza, and may be unable to detect variant or pandemic strains, and negative results can give the false impression that patients do not have H5 influenza. We will develop rapid, point-of-care tests based on highly conserved parts of the virus, so that all H5 strains (current and future) can be detected with equal sensitivity, along with the H1 and H3 strains that are currently found in man to provide a definitive diagnosis. These tests will be valuable in the identification and differentiation of pandemic influenza cases, allowing better use of public health resources, especially against a background of continuing standard (H1 and H3) influenza infections.Read moreRead less

The Australian Burden of Disease project quantifies the relative burden associated with each disease. New estimates are to be released this year will outline the magnitude of burden associated with dementia now and estimate that for the year 2023. Although the projections use the best data available, three improvements to the methodology would improve the accuracy of the dementia burden estimates. First, the dementia calculations currently use a “disability weight” metric derived from a Dutch study. This is problematic in that the weights do not reflect an Australian experience of dementia, nor do they reflect the preferences of people closely affected by the disease (e.g. carers). Second, the dementia estimates do not include cases of mild cognitive impairment (considered a precursor state of dementia). Hence the dementia estimates may not estimate the full impact of dementia in Australia. Finally, there is no evidence that the method used by the Burden of Disease study to account for the impact of disease comorbidity adequately deals with the comorbidity associated with dementia. Consequently, there is need to develop a new and comprehensive set of disability weights for dementia that are Australian-based, include all stages of dementia severity and account for comorbidity. The proposed project aims to develop a new set of empirically derived Australian-based disability weights for dementia. The project will entail three studies. The first study will generate empirically based case vignettes that describe a range of dementia case scenarios. These descriptions will then be used in rating exercises (Study 2) to develop new disability weights. The second study involves Australian health practitioners, carers and lay persons reading case vignettes and completing health valuation rating exercises to generate new disability weights for dementia. The third study uses the new disability weights to re-calculate the burden of disease estimates for dementia. The new estimates will be compared to those reported by the 2007 Australian Burden of Disease project. In knowing the accuracy of the estimates, policy makers can use the burden data for dementia with confidence when engaging in service planning for the future.Read moreRead less
Statistical Methods And Algorithms For Analysis Of High-throughput Genetics And Genomics Platforms

Summary
Through rapid advances in high-throughput -omics technologies, the number of phenotypes and the number of genotypes in gene mapping studies are or will be orders of magnitudes larger than in previous studies. Current algorithms and analysis methods have not kept up with the speed of data collection, nor has the training of qualified researchers. We will develop quantitative trait loci (fine) mapping analysis methods and bioinformatics algorithms and train (post)graduates in these research areas.
