Summary
AIMS This study will assess how melanoma is diagnosed in Queensland, and if improvements can be made. It will assess if skin screening gives earlier diagnosis of some melanomas, and also if it leads to the diagnosis of some thin melanomas which would not progress if left alone. SIGNIFICANCE Melanoma is the most common invasive cancer in Queensland, with some 1,963 people diagnosed annually with the disease. The outlook for these patients varies dramatically with the depth of invasion of melanoma ....AIMS This study will assess how melanoma is diagnosed in Queensland, and if improvements can be made. It will assess if skin screening gives earlier diagnosis of some melanomas, and also if it leads to the diagnosis of some thin melanomas which would not progress if left alone. SIGNIFICANCE Melanoma is the most common invasive cancer in Queensland, with some 1,963 people diagnosed annually with the disease. The outlook for these patients varies dramatically with the depth of invasion of melanoma. Melanoma diagnosed and treated when very thin has an excellent long-term outcome, whereas the outcome for deeply invasive melanoma is much less favourable. Improvements to diagnosis are currently our best hope of reducing deaths and serious distress from this disease. This will be the largest study in the world of the process of diagnosis of melanoma: information on how melanoma presents, and the time between presentation and diagnosis will be compared between thin and deeply invasive melanoma. Results may indicate areas for improvement in education or health services. The use of screening, either by individuals themselves or by health professionals, has the potential to achieve early diagnosis. However, there is currently no good information on whether screening is actually effective. This study will assess the impact of self-screening and doctor screening on the depth of invasion of melanoma at presentation, and ultimately on the likelihood of dying from melanoma. The study will also assess the potential impact of screening on the over-diagnosis of lesions which while labeled as melanoma, may in fact be biologically non-progressive. This is an important issue of current concern internationally. This study will be one of only two studies in the world currently addressing this issue. This project is directly relevant to the early detection and optimum management of the most common invasive cancer in Queensland, and will have relevance internationally.Read moreRead less
Epidemiology Of Middle-age BHR: A Prospective Study From Childhood To Middle Age
Funder

Funding Amount
$593,840.00
Summary
Increased airway reactivity (BHR) in middle-age increases the risk of chronic respiratory diseases (CRDs) in old age, which are recognised as a major public health problem. Knowledge on the causes of these conditions is currently limited. This project will improve our understanding of the childhood and adult causes of increased reactivity of the airways in middle-age. Such knowledge will help in identifying preventive strategies for middle age BHR and thereby CRDs in old age.
Comprehensive Assessment Of Genetic And Environmental Risk Factors For Melanoma: A Population-based Family Study
Funder

Funding Amount
$150,679.00
Summary
Excessive sunlight can cause melanoma, a serious type of skin cancer. However, there are other factors including a person's genetic make-up that are thought to put some people at higher risk. Many 'healthy' people have small changes in their genes that might make them more likely to develop melanoma. We need to know more about these genetic factors. Our study will investigate how particular small genetic changes influence a person's likelihood of developing melanoma.
Reducing The Injury And Disease Burden Attributable To Alcohol: Methodological, Aetiological And Intervention Studies.
Funder

Funding Amount
$408,412.00
Summary
The research examines the influence of individual, social and environmental factors on drinking behaviour, and seeks to determine the effectiveness of strategies to prevent alcohol-related harm, with a particular focus on youth drinking. A series of studies is proposed, examining the validity of methods for measuring drinking behaviour; social and environmental factors, and interventions. The findings will have relevance to reducing the burden of alcohol-related injury and disease in Australia.
Assessing The Impact Of Climate Change On The Transmission Of Mosquito-borne Diseases In Australia

Funding Amount
$346,689.00
Summary
Global climate change has potentially serious effects on the transmission of mosquito-borne diseases (MBDs). Bayesian spatiotemporal models will be developed to explore the underlying mechanisms of the current distribution of MBDs and to forecast future changes in pattern of these diseases. The model will be useful in examining where and when MBDs are likely to occur and how the future MBDs control strategies and prevention efforts need to be applied and strengthened in Australia.
What Do Australians Think About Privacy And Participation In Epidemiological Research?

Funding Amount
$443,015.00
Summary
There is very little research available, in Australia or internationally, about what the general public considers privacy to be; or how important privacy protection is in the context of high and low risk epidemiological studies. We also know little about what affects willingness to participate in epidemiological research. Our research will provide an evidence base, and develop resources for the legislature, the NHMRC, ethics committees and researchers.

Fracture, the ultimate consequence of osteoporosis is associated with significant morbidity, mortality and economic costs. The Dubbo Osteoporosis Epidemiology Study, starting in 1989, with over 2000 women and men, is one of the longest running epidemiological studies in osteoporosis worldwide. It has been at the forefront of epidemiological advances in osteoporosis. It has identified osteoporotic fracture risks including low bone density and bone loss, muscle weakness and postural instability, as well as the extent of the problem in men, and the significant costs, ill-heath and mortality associated with fracture. Despite the clarification of risk factors over the past decade, there are significant gaps in knowledge about osteoporosis, particularly in the accurate prediction of fracture risk and in identification of factors related to fracture-associated mortality and survival post fracture. Although bone density is one of the best predictors of fracture risk, it incompletely discriminates between those who will fracture from those who will not. Although a number of clinical risk factors, and other measures of bone strength, such as quantitative ultrasound and geometry, have been shown to be independent predictors of fracture risk, it is not clear that these measures can be integrated with BMD to improve fracture prediction. The aim of the current study, is to develop and validate models using bone density, other measures of bone strength and clinical parameters that will more accurately predict fracture risk and mortality following fracture in older men and women. The more precise identification of those at high risk of fracture and at risk for poor outcomes following fracture will provide a rational basis for the development of more cost effective interventions for prevention of fracture and its associated morbidity and mortality.Read moreRead less
