Summary
Multiple Sclerosis (MS) is a severely debilitating neurodegenerative disease, affecting over 16,000 Australians. There is a need to examine which factors drive the progression of this disease. We examine the role of two viral infections on MS activity. It has the potential to contribute to antiviral interventions that might prevent relapses and-or decrease the clinical progression of this debilitating disease.

Summary
Chronic diseases such as coronary heart disease, breast cancer, prostate cancer and non-insulin dependent diabetes are responsible for a significant burden of ill-health in society. Studies of familial aggregation are important in determining the relative magnitude of genetic and lifestyle-environment factors associated with chronic diseases, and in identifying individuals and families at high risk, even in the absence of conventional risk factors. The findings have implications for health promo ....Chronic diseases such as coronary heart disease, breast cancer, prostate cancer and non-insulin dependent diabetes are responsible for a significant burden of ill-health in society. Studies of familial aggregation are important in determining the relative magnitude of genetic and lifestyle-environment factors associated with chronic diseases, and in identifying individuals and families at high risk, even in the absence of conventional risk factors. The findings have implications for health promotion in the general population and disease prevention in those identified to be at high risk. An outstanding characteristics of these studies is that many participants had an event at some unknown time before the entry. This project aims at adapting current methods to properly account for events before entry and to provide estimates of familial aggregation between parents, between children and between parents and children in the same model. Furthermore, it provides freely available software for proper familial analyses which have not had any feasible numerical methods (or software). In addition, it provides estimates of familial aggregation of coronary heart disease in Busselton families which has longer follow-up than most other studies. This project is very cost effective as the Busselton Health Study consists of a series of cross-sectional surveys since 1968 and currently has hospital morbidity and death follow-up from medical record linkage until the end of 1997.Read moreRead less
Incidence And Outcome Of Stroke In Rural South Australia

Summary
We propose to undertake a population-based study of the incidence, management and outcome of stroke (survival, disability, recurrent stroke) in geographically defined segments of rural South Australia and compare these with equivalent data, collected during the same period in a defined sector of metropolitan Adelaide. It is hard to over-state the value of this information for planning health services of many kinds for the next decade.
The Real And Changing Atherothrombotic Disease Burden And Secondary Prevention

Summary
Absolute numbers of Australians with diseased narrowed blood vessels in the heart, brain or leg are increasing, dominating health priorities and expenditure. By linking Department of Health datasets, without identifying individual's, trends in hospital admissions, prescription of chronic protective medications and the cost consequences to the health system among and across conditions will be determined. The findings will provide quality measures of hospital care and inform quality improvement
Risk Factors For Gastro-oesophageal Reflux Disease And Barretts Oesophagus In A Prospective Cohort Study

Summary
Heartburn caused by acid reflux is a common problem in Australia. In 2003, drugs used to treat disorders caused by acid problems, such as heartburn, cost the PBS more than $500 million. Heartburn probably causes a disease of the oesophagus called Barrett's oesophagus, which in turn is a cause of cancer of the oesophagus. The aim of this study is to identify risk factors for heartburn and Barrett's oesophagus, so that we can find ways to prevent them occurring.
Anogenital Human Papillomavirus Infection And Its Outcomes In Men

Summary
Anal human papillomavirus (HPV) infection is common in homosexual men. Low risk types cause anal warts and high risk types of HPV cause anal cancer. This study will determine incidence and risk factors for HPV infection in a cohort of young homosexual men, the association of anal warts treatment with HIV risk, and the specific association of HPV subtypes with anal cancer. The findings of this research will help delineate the potential benefits of HPV vaccination in this population.
Low-yield Cigarettes And Diminution Of Small Airways Lung Function In Long-term Smokers

Summary
The modern cigarette has been designed to produce low yields of tar when the tobacco in the cigarette is burnt. The tar contains human carcinogens, and monitoring and regulating yields of tar has long been part of the comprehensive tobacco control strategy in Australia. This focus on tar has given an implicit endorsement of the low-yield cigarette as a safer cigarette. Recently, however, controversy has emerged about whether smoking low-yield cigarettes has reduced the harm done by smoking.

The tar contains human carcinogens, and monitoring and regulating yields of tar has long been part of the comprehensive tobacco control strategy in Australia. This focus on tar has given an implicit endorsement of the low-yield cigarette as a safer cigarette. Recently, however, controversy has emerged about whether smoking low-yield cigarettes has reduced the harm done by smoking. The concern is that adenocarcinoma of the lung, a type of lung cancer that is most common in the small peripheral airways, has increased in frequency. This could be because the low-yield cigarette, with reduced yields of nicotine as well as tar, is smoked more intensely by smokers to compensate for the low nicotine. By smoking more intensely, we mean taking larger and more frequent puffs, inhaling the smoke deeply into the lungs, and holding the breath before expiring. This method of smoking would result in more tar particles being deposited in the peripheries of the lung where adenocarcinoma is most common. Because cigarette smoking has been linked also with other structural changes in the small airways of the lung, resulting in obstruction of airflow, we will test whether smoking low-yield cigarettes is associated with greater obstruction of the small airways than is smoking higher-yield cigarettes. To test whether the mechanism is the method of smoking, we will carefully describe and quantify each subject's pattern of smoking including the deposition of smoke-like Technegas particles in the peripheral lung.Read moreRead less

Summary
Wildfires have become more frequent and severe the world over and the health impacts of the associated air pollution is a major gap in the current evidence. Working with lead agencies in air quality regulation, public health and fire management I will examine and compare the health effects of air pollution from deliberate burns, bushfires, wood heaters and other sources of air pollution. The research will focus on respiratory and heart disease to inform public health and individual patient care.
