Summary
In this population-based study we will generate evidence, both environmental and genetic, for defining fracture risk in Australian men and women. This will help identify individuals likely to sustain fragility fractures so that suitable therapies can be recommended. The data will be useful for developing prognostic models in both a clinical setting and for genetic screening programmes.
Osteoporotic Fracture-Mortality Association And The Effect Of Anti-osteoporosis Treatment: A Multinational Study

$84,800.00
Summary
Osteoporosis burden is due primarily to osteoporotic fractures resulting in economic and public health burden, increased disability, further fracture risk and more importantly early death. However, it remains under-treated although treatment reduces the number of fractures and may reduce early death. This study aims to understand which types of fractures result in early death and for which age groups and whether osteoporosis treatment does or does not reduce early death.
International Orthopaedic Multicenter Study In Fracture Care (INORMUS)

Summary
INORMUS is a global multi-centre prospective cohort study in 40,000 patients with musculoskeletal trauma (e.g. fractures or dislocations) to determine the incidence of major trauma complications (i.e. mortality, re-operations, and infections) and to examine a number of factors that may predict early complications. This study will allow us to address fundamental questions for the millions of adults worldwide who experience trauma annually and will have immense public health implications.
The study is the largest fracture care study will provide precise and accurate estimates of outcome in the early post injury period and enable determination of modifiable factors predicting major outcomes In NSW, the study results will identify limitations of the present compulsory third party (CTP) insurance scheme and help create a more efficient insurance scheme. This proposal involves an elite collaboration of researchers from Canada, Australia and South Asia.
Long Term Supplementation With Retinyl Palmitate (Vitamin A) And The Risk Of Bone Fractures: A Population Based Study.

Summary
Osteoporosis is a major health problem in Australia and other western industrialised countries where populations are increasingly ageing. In Australia, the number of hip fractures is expected to increase by 36% between 1996 and 2006, owing to the rise in elderly aged 85 years and over. This is in contrast to projections in Europe and North America, where the number of hip fractures are expected to double by 2026 and then stabilise.

In Australia, the number of hip fractures is expected to increase by 36% between 1996 and 2006, owing to the rise in elderly aged 85 years and over. This is in contrast to projections in Europe and North America, where the number of hip fractures are expected to double by 2026 and then stabilise. Clarification of the role of vitamin A in bone health is pertinent, given that the popularity of supplement use has increased markedly in western industrialised countries over the past two decades. Around 37% of the adult population in Australia is thought to take a supplement regularly and figures range from 28% to 54% of adults in the US, with women and adults aged over 49 years being more likely to use supplements. Furthermore, the fortification of food with minerals and vitamins is increasing. For all of these reasons, is it imperative that the role of vitamin A in inducing fractures be clarified. Results from this study will contribute to knowledge about the safety of retinol and beta carotene supplements in relation to bone health, which is especially relevant to people at risk of osteoporosis, and people who take vitamin A supplements. We will also be able to clarify the upper levels of dietary retinol, beta carotene and vitamin A intake beyond which fracture risk increases. Because of the age range of subjects in our study, our results should be applicable to the whole population, not only the elderly or post menopausal. The results of our study will be useful to agencies such as Food Standards Australia and New Zealand which regulates our food supply.Read moreRead less
Predicting The Individual Risk Of Prostate Cancer In Australian Men

Summary
Prostate cancer is a major cause of disability and death in Australian men. A number of factors, particularly age and family history, influence the risk of prostate cancer but, in contrast to breast cancer, we don't know what is the risk of developing prostate cancer over a period of time for a man with a specific set of risk factors. In fact, while a number of statistical models have been developed that use a woman's risk factor profile to estimate her risk of breast cancer, none is currently a ....Prostate cancer is a major cause of disability and death in Australian men. A number of factors, particularly age and family history, influence the risk of prostate cancer but, in contrast to breast cancer, we don't know what is the risk of developing prostate cancer over a period of time for a man with a specific set of risk factors. In fact, while a number of statistical models have been developed that use a woman's risk factor profile to estimate her risk of breast cancer, none is currently available for prostate cancer. We will apply standard statistical methods to existing data from the Australian Risk Factors for Prostate Cancer study and from the Australian Institute of Health and Welfare to develop a prostate cancer risk prediction model. We will test how factor like age, detailed family history, diet, baldness status and possibly previous PSA tests and prostate biopsies predict the risk. After developing the model, we will test the accuracy of the predictions in three ways. First, using existing data from the Australian Prostate Cancer Family Study, we will see whether the number of cases in a group of men is close to the number predicted by the model (calibration). Second, to test whether the model discriminate well men who develop prostate cancer from those who do not, we will collect family trees in a sample from the Melbourne Collaborative Cohort Study. We will use these data also to estimate the optimal cut point: men above this level of risk will be considered at high risk. Third, we will apply the model to existing data from the Dutch Prostate Cancer Family Study (DPCFS) to test whether the optimal cut point identify high-risk men and to validate the model in a non-Australian population. Finally, we will prepare a computer package that health professionals will use as decision-making tool in different scenarios including individual cancer risk assessment, design of prevention trials and targeting prevention programs to high-risk men.Read moreRead less

Summary
Studies investigating thousands of genetic markers have revolutionised our understanding of genes involved in cancer, and shown that a single gene can be associated with multiple cancers. We will conduct the largest ever study to find new genes for endometrial cancer, the most common gynaecological cancer. Our unique approach will examine >11million markers across the genome, some specifically in regions known to be important for other cancers.

Summary
Oesophageal cancer is a rapidly fatal disease which is becoming more common in Australia, the United States and other industrialised nations. This study will examine the mechanisms leading to the development of oesophageal cancer and aims to measure the effects of genes and environment on the burden of cancer. Ultimately, this research will help target persons at highest risk so that screening, prevention and surveillance efforts can be directed more effectively.
Obesity, Pre-diabetes And Future Risk Of Diabetes: Maximising The Evidence, Minimising The Cost

Summary
The overarching aim of this proposal is to reliably determine how best to identify people at high risk of developing future diabetes. We will do this by using information on biological and behavioural risk factors that was collected on nearly 200,000 people many years ago and who were subsequently followed up to see who developed diabetes. This information will be used to create a risk prediction tool for spotting individuals most at risk of developing diabetes at some point in the future.
