Summary
I believe I can describe a new subtype of lung cancer, which has never been classified by the World Health Organization. This has been previously mis-classified or simply ignored. My hypothesis is that this is a distinct disease by virtue of patterns of genetic abnormalities as well as features visible under the microscope. I also believe it is one of the most aggressive cancers and needs new treatments.
False Positives In The Diagnosis Of Sexually Transmitted Chlamydia Trachomatis Infection In Children

Summary
Chlamydia trachomatis causes sexually transmitted infections, and also the eye disease trachoma. The detection of Chlamydia in urine sample from a child can be seen as evidence for sexual abuse. We will assess the potential impacts of three mechanisms that could conceivably lead to urogenital Chlamydia diagnosis in a child in the absence of sexual abuse: contamination of the urogenital site with ocula Chlamydia, contamination of urine samples after collection, and diagnostic test malfunction.

Summary
There are substantial risks of inadequate pain assessment and management in persons with cognitive impairment and particularly in those with communication problems. Undetected or under-treated pain can have serious adverse effects on frail older adults including poorer cognitive performance, increased levels of depression, anxiety and disruptive behaviours, a reduced quality of life and higher levels of functional disability. These adverse effects contribute to greater demands for daily nursing ....There are substantial risks of inadequate pain assessment and management in persons with cognitive impairment and particularly in those with communication problems. Undetected or under-treated pain can have serious adverse effects on frail older adults including poorer cognitive performance, increased levels of depression, anxiety and disruptive behaviours, a reduced quality of life and higher levels of functional disability. These adverse effects contribute to greater demands for daily nursing care and a corresponding increase in health care costs. The present proposal aims to develop more sensitive, reliable and valid questionnaire and non-verbal measures of pain in older adults with cognitive impairment and particularly in those with verbal communication problems. By completion, the present studies should provide much needed information on the reliability and validity of several different types of verbal and non-verbal indicators of possible pain. This research should lead to improved pain assessment and management for the growing segment of the population who suffer from pain and impaired cognitive function.Read moreRead less
GENETIC FACTORS AND REGIONAL BRAIN ATROPHY IN THE DIAGNOSIS OF DEMENTIA WITH LEWY BODIES

Summary
The number of people with dementia is increasing in Australia as people live longer. Dementia sometimes has a genetic basis and identification of such cases has improved our understanding of the events leading to the destruction of the brain tissue. In the vast majority of people, the degenerative changes were previously thought to be as a result of Alzheimer's disease. However, our recent research, funded by the NHMRC, confirms international findings showing more than 25% of people with dementi ....The number of people with dementia is increasing in Australia as people live longer. Dementia sometimes has a genetic basis and identification of such cases has improved our understanding of the events leading to the destruction of the brain tissue. In the vast majority of people, the degenerative changes were previously thought to be as a result of Alzheimer's disease. However, our recent research, funded by the NHMRC, confirms international findings showing more than 25% of people with dementia have a different disease called Dementia with Lewy bodies or DLB. Of course identifying these patients occurs at death when the cells in the brain can be examined for Lewy bodies. We now know that the brain degeneration differs significantly in patients with this disease. However, it is still not possible to identify DLB in life with any certainty. This project aims to develop objective methods to clinically differentiate dementia patients. We will seek out families in which genetic influences may underly the disease and determine whether these factors differ from those found in other dementing illnesses. Also, our preliminary studies have observed volume loss in a particular brain region in pathologically confirmed DLB patients. We wish to do further measurements to determine if tissue loss in this region can clinically differentiate DLB patients. In addition, we will determine the reasons for the tissue loss by careful pathological studies.Read moreRead less
Biocompatible Gadolinium-free Contrast Agents For Molecular Targeted MR Imaging

Summary
Building on the biomedical engineering of USPIOs, this project expects to generate new probing tools for non-invasive molecular imaging and affect subsequent clinical imaging through earlier and more accurate diagnosis of diseases. The project will allow the delivery of new knowledge in the emerging field of nanomedicine with high clinical translation potentials.
Rapid, Point Of Care Diagnostic Tests To Differentiate HA Subtypes In Patients Samples

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

Predicting the diagnostic performance of individuals and organisations. This project aims to address diagnostic error in advanced technology systems, by providing a mechanism to assess and improve individual diagnosticians’ performance. Organisations that rely on their employees’ diagnostic skills rarely assess them once the operators become qualified, so there is no basis for interventions that might prevent diagnostic errors affecting thousands. This research tests a new method of assessing diagnostic skills based on how skilled operators respond to cues. This project will test how employees’ diagnostic skills change and whether this change corresponds to measures of organisational performance. This research is expected to provide organisations with a tool to pre-empt diagnostic errors that could minimise costs to the economy.Read moreRead less
Predicting Obstructive Sleep Apnoea Using 3D Craniofacial Photography

Funding Amount

Summary
Sleep Apnoea is a common medical condition associated with snoring and collapse of the throat during sleep. Diagnosis of sleep apnoea involves an overnight sleep study in a specialised laboratory, which is expensive and time consuming. It is possible that sleep apnea could be diagnosed from a 3-dimensional photograph of the face. This study will define the relationships between sleep apnea and 3D face photographs in 956 young adults and 1,200 of their parents, and 3,000 sleep clinic patients.

Summary
Pregnancy associated diabetes is a significant complication of pregnancy that has adverse health effects for both mother and baby. We have developed a multivariate algorithm to identify women during their first trimester of pregnancy who will subsequently develop gestational diabetes. The test requires further clinical validation to develop a commercial product and to implement it into clinical practice.
