Summary
Peritoneal dialysis (PD) is a form of home dialysis that is both substantially cheaper and associated with better early survival than standard hospital-based haemodialysis. Its use in Australia has been severely limited by poor outcomes compared to the rest of the world. This international study aims to identify “real world” PD centre practices that will lead to better outcomes for Australian patients, greater uptake of home dialysis and health savings of tens of millions of dollars annually.
A Prospective Study Of The Influence Of Health-related Lifestyle Factors On DNA Methylation

Summary
It is known that DNA methylation can lead to disease. We aim to discover what causes DNA methylation to change. This could open the way for new methods of prevention and treatment of many diseases. We will study 1200 people to assess how the methylation of their DNA is influenced by changes in their smoking habits, alcohol consumption, vitamin intake, body size, blood sugar and cholesterol levels. We want to know whether these changes lead to undesirable (or desirable) changes in DNA methylation

It will assess the prevalence of OSA in a well characterised cohort (the Raine Cohort), representative of the population of young adults in Western Australia. It will define the clinical picture and risk factors associated with abnormal breathing during sleep and will use the extensive longitudinal data collected from 18 weeks gestation until 23 years of age to quantify early life developmental and environmental pr ....This project will characterise Obstructive Sleep Apnoea (OSA) in early adulthood.

Summary
The Fremantle Diabetes Study Phases I and II continue to make important contributions to our understanding of the natural history of diabetes and will be a major focus of the research supported by present application. Studies of malaria and severe bacterial infections in Papua New Guinean children that have regularly contributed to changes in national and regional treatment protocols will also continue under the supervision of the applicant.
We will investigate whether there are particular patterns of DNA methylation in people who develop gastric cancer. This could provide a means of identifying people at high risk of developing the disease, which may assist with early detection. This would be expected to markedly improve survival. If we can identify lifestyle factors associated with gastric cancer methylation there may be opportunities for prevention of the disease.
Infections, Inflammatory Markers And Prostate Cancer Risk

Summary
Prostate cancer is the leading cancer for Australian men but apart from getting older and having a family history of prostate cancer we do not know what causes it and nothing can be done to prevent it. This project follows up recent suggestions that some prostate cancer might be due to infections by bacteria and viruses. We will look for evidence of infection in blood samples and prostate tissue that we have collected from men with prostate cancer and from controls without prostate cancer.

This proposal aim to follow up evidence from a number of studies that genetic and non-genetic markers of hormonal action in different periods of a man's life are associated with prostate cancer risk using a collection of three large, independent epidemiologic studies on prostate cancer named the Prostate Cancer Program.

A principal objective is to collect exposure data on acne and digit ratio, and genotype cases and controls across the studies of the Prostate Cancer Program for common genetic variants in 4 candidate genes in the hormonal pathway. The established risk factors for prostate cancer are only age, race and family history. We anticipate that this project will cast light on the role of hormones in prostate cancer and that we will identify new markers of risk of prostate cancer and markers of disease aggressiveness. These outcomes will help us identifying men who are at risk for prostate cancer to target screening and surveillance, and plan prevention strategies. Furthermore, they will also form the basis for research on treatment targets.Read moreRead less

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

This project forms the central component of a larger set of studies which investigate competing psychiatric, immunological and infective models of the causes of a number of chronic fatigue syndromes, including post-infective fatigue.

The study takes place in western NSW where certain viral illnesses (Glandular Fever, Ross River Virus) and a non-viral infection (QF) are common and have been associated with prolonged fatigue states. The study follows patients from laboratory-documented infections with appropriate infective, immunological and psychological measures throughout the course of their acute illness, the early recovery period and for the next 12 months. These patients are compared with people who present to their doctor with other forms of medically-unexplained fatigue. Very few previous studies have used an appropriate prospective design and followed patients with documented illness from the onset through to the development of specific forms of chronic fatigue. Further, the study is unique in terms of the range of viral and non-viral agents being investigated. It relies on the combined psychiatric, immunological and infective disease expertise of a group of researchers with an international reputation for the successful completion of such multidisciplinary projects. The initial phase of the study has demonstrated that the research team has the capacity to complete this project. Initial results have already demonstrated the potential roles of psychological and immunological factors in causing some cases of prolonged fatigue. Further, the initial results indicate that two key symptom sets (fatigue, psychological distress) can be adequately measured during the recovery phase and are predicted by differing psychological factors. The study will result in the identification of different psychiatric risk factors to chronic fatigue, assist development of clear diagnostic guidelines for post-infective fatigue and guide relevant aetiological and treatment research.Read moreRead less
