Summary
In 1990 we set up a long-term study of diet and health. The aim was to measure diet and other risk factors in healthy people in order to see how they might affect future development of cancer. To do this we recruited 41,500 people aged 40 to 69, measured what they ate and drank, and collected information on other aspects of lifestyle, medical history, and family history of common diseases. All had height and weight and blood pressure measured and gave a blood sample. People were selected so that ....In 1990 we set up a long-term study of diet and health. The aim was to measure diet and other risk factors in healthy people in order to see how they might affect future development of cancer. To do this we recruited 41,500 people aged 40 to 69, measured what they ate and drank, and collected information on other aspects of lifestyle, medical history, and family history of common diseases. All had height and weight and blood pressure measured and gave a blood sample. People were selected so that men and women and migrants from Italy and Greece would be included. In this way we could widen the range of dietary habits, other lifestyle factors and genetic variation (measured in DNA from blood). Since then participants have completed another questionnaire and instances of disease have been noted from self reports and from examining medical records. We want to analyse data from 700 men in the study who have developed prostate cancer (PC). First we will analyse data collected on all 17,000 men (collected when joining the study, and at follow up). Next we will use data from only the 700 men with PC and 1400 men who have not developed PC. This study will focus on measuring substances in the blood. We want to measure a range of fats, vitamins, antioxidants and phytoestrogens, as well as male sex hormones and related substances. In the DNA from the blood we plan to measure variations in genes that influence how male sex hormones and other growth factors important in the prostate are produced and used. We will then be able to estimate what affect these factors have on the risk of getting PC. We will also be able to see if any of them act together to make the risk of PC much higher in certain men. This work should identify what lifestyle factors could reduce the risk of PC. It should also identify what genetic variations are associated with increased risk of PC and thus identify a sub group of men who might benefit from early medical attention or from changes in lifestyle.Read moreRead less
Quantifying The Effectiveness Of Pertussis Vaccine In Older Adults

Summary
Pertussis is the most poorly controlled vaccine preventable disease in Australia. Childhood pertussis is a well-known public health problem but adult pertussis is also common and has a significant burden on the health system, especially in adults over 65 years. Pertussis vaccines for adults are currently not funded by our national immunisation program. This project will provide vital data to inform whether pertussis vaccination is cost-effective in older Australian adults.
Characterising The Muscarinic Receptor Deficit In Schizophrenia

Summary
Post-mortem examination of the brains of schizophrenia patients reveals a substantial loss of muscarinic receptors. This is likely to be clinically very important if it can also be confirmed in living patients. Having developed a new scanning technique that shows muscarinic receptors in the living brain, we will now scan patients with schizophrenia to see if they also show this receptor loss, and see how it affects them. This could open new doors to understanding and treating the disease.
Case-cohort Study Of The Association Between Pertussis Vaccination In Infancy And The Risk Of IgE-mediated Food Allergy.

Summary
Allergic diseases are one of the most important causes of chronic morbidity among children in Australia. This is a retrospective case-controlled trial, utilising data from the Australian immunisation register and cases of confirmed food allergy, to examine the role of vaccination in protection against food allergy. If a relationship between the type of vaccination and protection against allergy is found, this would have implications for allergy prevention and immunisation policy.
Improving Warfarin Management- Identifying Risk Factors For Bleeding And Improving Monitoring Mechanisms

Summary
Warfarin is a drug commonly used in the elderly to prevent blood clots. While a very effective drug, it is also a dangerous drug and should be closely monitored. While we know many of the reasons why problems occur, we do not know whether organisation of care, mental health or social issues such as community support influence how well warfarin is managed. These are important questions to answer, so that we can make significant inroads into preventing death and disability from warfarin.
