Summary
National drug surveys and surveillance systems have detected sharp increases in the use of 'psychostimulant' drugs such as the amphetamines, ecstasy and cocaine. The level of harms associated with excessive use of these drugs, such as mental health problems and drug dependence, has also increased, as has the use of these drugs via injection. These increases in the prevalence of use and related harms have also been detected internationally. Previous research on psychostimulant drugs, in Australia ....National drug surveys and surveillance systems have detected sharp increases in the use of 'psychostimulant' drugs such as the amphetamines, ecstasy and cocaine. The level of harms associated with excessive use of these drugs, such as mental health problems and drug dependence, has also increased, as has the use of these drugs via injection. These increases in the prevalence of use and related harms have also been detected internationally. Previous research on psychostimulant drugs, in Australia and overseas, has suggested that using these drugs in particular ways might be associated with a greater chance of contracting HIV and other blood-borne viruses such as hepatitis C (eg through sharing needles and syringes or other equipment associated with injecting drugs); sexually transmitted infections and other sexual health problems (eg through engaging in unsafe sex); and of being involved in violent incidents. Despite this previous research, however, little is known about the specific social and cultural contexts associated with psychostimulant-related harms, and this has stymied the development of appropriate responses to prevent such harms occurring. This research project will provide a greater understanding of the individual, social and cultural factors associated with pychostimulant-related harm through an innovative combination and integration of anthropological and epidemiological research methods known as 'ethno-epidemiology'. In order to access a range of psychostimulant-using contexts, research will focus on three sites: street-based drug users in Sydney, club drug users in Melbourne, and home-based recreational drug users in Perth. These groups have been chosen because they have high prevalences of psychostimulant use. The research project will provide important data that will inform future interventions, improve multidisciplinary models for drug research, and build Australia's capacity to conduct cutting-edge public health research.Read moreRead less
Understanding The Barriers To Improved Access, Engagement And Retention Of Methamphetamine Users In Health Services

Summary
Drug surveys show widespread use of methamphetamine. Its regular use, particularly via injection, is associated with a range of serious harms, including drug dependence, psychosis, viral infection and violence. In order to improve access, engagement and retention of methamphetamine injectors in drug treatment and other health services, and thereby reduce these harms, further research is urgently needed to better understand their healthcare needs and the existing barriers to service utilisation.
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. Findings will be used for risk prediction models ....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.

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.
Modelling Of Clinic And Ambulatory Blood Pressure On Cardiovascular Risk And Outcomes

Funding Amount
$133,957.00
Summary
Whilst ambulatory blood pressure monitoring data has been shown to be a good predictor of cardiovascular events, there remains controversy as to its utility in clinical practice. This project will use data from existing population and clinical cohort studies to examine the role of ambulatory blood pressure in risk assessment and hypertension management in Australia and around the globe. The findings are likely to have a major impact on clinical guidelines for hypertension management.

Funding Amount
$470,136.00
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.
Young Onset Colorectal Cancer: Genetics Pathology And Environment

Funding Amount
$439,180.00
Summary
There has been a steady increase since 2002, in the age-standardised incidence of CRC in males under 45 years in Australia, contrasting with the stabilisation in incidence of CRC in males of age 45 years and over. Persons under 50 years are not routinely screened unless they have a significant family history of CRC. Young-onset rectal cancer is associated with late presentations and with a higher mortality. This proposal will address the possible risk factors for young-onset CRC.
