Summary
The hepatitis C virus (HCV) is a major public health problem affecting over 170 million people worldwide. In Australia an estimated 157,000 people have HCV and are at risk of serious disease, and 16,000 new infections occur each year. Treating HCV-related disease is expensive, and this healthcare burden is projected to grow significantly in coming years. Almost all new HCV infections in Australia occur among injecting drug users (IDUs), and despite our world-leading prevention programs, the viru ....The hepatitis C virus (HCV) is a major public health problem affecting over 170 million people worldwide. In Australia an estimated 157,000 people have HCV and are at risk of serious disease, and 16,000 new infections occur each year. Treating HCV-related disease is expensive, and this healthcare burden is projected to grow significantly in coming years. Almost all new HCV infections in Australia occur among injecting drug users (IDUs), and despite our world-leading prevention programs, the virus is spreading. Consensus is emerging that the best hope for control of HCV and related disease lies in a vaccine; our research will lay much of the groundwork for its development. The applicants' research to date shows that IDUs are being infected with HCV more frequently than previously assumed, that many carry multiple strains, and that dominant strains vary rapidly in individuals over time. These results reinforce the view that our prevention methods will not reduce infection rates and that current anti-viral treatments are not the solution. Nevertheless, we also found that some IDUs remain free of HCV infection despite risky behaviour with infected associates; intensive study of the immune functioning of these persistently non-infected individuals holds promise for vaccine development. In our proposed research, a collaboration of leading Australian epidemiologists, virologists and immunologists, we will recruit 210 young IDUs and follow them regularly for two years. Recruits will describe their social networks and nominate IDUs with whom they inject, provide blood samples and be interviewed about their behaviour at 3-month intervals. Individuals with recent and resolved HCV infection, change of dominant strain and lack of infection despite risky behaviour will be identified and their blood analysed for genetic factors that may be linked to immune protection. The outcomes will be crucial to the development and trialling of a vaccine against HCV.Read moreRead less

Summary
My research program aims to better understand the causes of cancer and factors that influence outcomes after cancer diagnosis. It employs classical and innovative cancer epidemiology and includes large-scale studies of cancer incidence, survival and risk factors in people with immune dysfunction. It also includes studies of lymphoid malignancies and ‘cancer of unknown primary’ origin.

Better Data To Inform Interventions To Reduce The Risk Of Stillbirth In Australia

Funding Amount

Summary
Stillbirth is a devastating experience for parents and families. Paucity of high quality data on causes and contributing factors is a major barrier to the development of research priorities and interventions to prevent stillbirths and improve the quality of care. This research will be a connected body of work that aims to better describe the epidemiology of stillbirth in Australia, contribute to the classification of stillbirths and determine the needs of parents in relation to autopsy consent.
Understanding Causes Of The Rising Incidence Of Thyroid Cancer – What Can Mutations In The BRAF Oncogene Tell Us About Causes And Diagnostic Pathways For Thyroid Cancer?

Funding Amount

Summary
The occurrence of thyroid cancer has increased rapidly over the last 25 years but the cause is unknown. The increase may reflect ‘over-diagnosis’ of less harmful cancers or greater exposure to causes of this cancer. Evidence suggests that a gene mutation (BRAF) in thyroid cancers is important in understanding the drivers of the increase. This study will examine the increase in thyroid cancer by investigating causes and diagnostic pathways considering the presence or absence of BRAF mutations.
Methylation As A Risk And Prognostic Factor For Breast Cancer

Funding Amount

Summary
DNA methylation is a process playing critical roles throughout life by altering the expression of genes. This study aims to investigate the potential use of methylation as marker of risk and early diagnosis of breast cancer in women with no clinical evidence of disease and marker of prognosis and response to treatment in breast cancer cases.
