Summary
Infection with streptococcus is responsible for causing more than 500,000 deaths each year, the majority of which are due to rheumatic fever and rheumatic heart disease, which contributes to cardiovascular disease. Our research is aimed at the development of a vaccine to prevent heart disease and involves targeting multiple molecules present on the bacterial surface. We will use a novel vaccine delivery system developed in the laboratory, which will enable the vaccine to be delivered nasally.

Summary
We will examine the practical feasibility, ethical and public acceptability, and likely cost effectiveness of a number of different ways of reducing tobacco smoking and the harm caused by smoking in Australia. These policy options will include: (1) more restrictive policies towards tobacco products (such as prohibiting tobacco smoking and creating a government monopoly on the manufacture and supply of tobacco); (2) encouraging smokers to switch from smoking cigarettes to less harmful ways of usi ....We will examine the practical feasibility, ethical and public acceptability, and likely cost effectiveness of a number of different ways of reducing tobacco smoking and the harm caused by smoking in Australia. These policy options will include: (1) more restrictive policies towards tobacco products (such as prohibiting tobacco smoking and creating a government monopoly on the manufacture and supply of tobacco); (2) encouraging smokers to switch from smoking cigarettes to less harmful ways of using nicotine, such as using nicotine patches or gum ; (3) using new biotechnologies to improve smokers chances of quitting (e.g. genetic screening of smokers to select the most effective way of helping them to stop smoking and vaccinating ex-smokers against the effects of nicotine); and (4) new biotechnologies that may prevent nonsmokers from beginning to smoke (e.g. vaccinating nonsmokers against the effects of nicotine) or reduce the chances of their developing tobacco-related diseases (e.g. screening the population for genes that predict an increased susceptibility to nicotine dependence and tobacco-related diseases). The project will provide important information that will assist government in formulating policies to reduce the rate of cigarette smoking in the Australian population below current levels.Read moreRead less

Chronic diseases such as heart disease, stroke and diabetes contribute greatly to the burden of disease in Australian society. Prevention of these conditions is a high priority for the health system. There is increasing evidence for the effectiveness of interventions to prevent chronic disease in those at high risk.

Prevention of these conditions is a high priority for the health system. There is increasing evidence for the effectiveness of interventions to prevent chronic disease in those at high risk. However the feasibility of intervening through general practice and other existing services has not been demonstrated. We have previously conducted research on a structured approach to helping patients with risk factors for chronic disease (such as smoking, poor nutrition, hazardous alcohol consumption and physical inactivity) including both cardiovascular disease and diabetes in general practice. This study aims to evaluate the impact of recalling patients to general practice for a visit to assess their risk of chronic disease and to help them to lower their risk by changes to smoking, diet, alcohol consumption and physical activity behaviours. Practices in the intervention group will receive training, practice visits, resources, and referral pathways to enable them to invite eligible patients to attend the practice for an assessment and management of their risk factors. This will include provision of education materials, support for behaviour change, referral to diet education and physical activity program and follow up. The feasibility of this type of vascular disease prevention intervention for high-risk patients has not been trialled previously in Australia. The findings of this research will help to inform Australian and State health policy especially the preventive care initiatives recently announced by the Council of Australian Governments. It will also inform practice leading to better guidelines for general practice preventive care, better support for general practice to provide preventive care for patients at risk of chronic disease and better support for patients to reduce their risk of chronic disease by changing their behaviour.Read moreRead less

These diseases are caused by infection with the larval stages of tapeworm parasites which have a worldwide distribution and cause substantial human morbidity and mortality. The parasites are transmitted to humans from animals. Methods for control of transmission of infection currently rely on public education and anthelmintic treatment of animals. These measures are often ineffective and there is an urgent need for new tools to help control transmission of these important diseases. Previous research has shown that the animal hosts of these parasites can be protected from infection by vaccination. Prevention of infection in the parasites' animal hosts has the effect of breaking the parasite life cycle and indirectly removes the source of infection for humans. This project will further develop an existing vaccine against hydatid disease, will develop a new vaccine against cysticercosis and will participate in initial international parasite control campaigns based on application of these vaccines.Read moreRead less
FAST-Australia: A Phase II Study Of Family History Screening For Chronic Disease Prevention In Primary Care.

Summary
Risk of developing certain cancers, heart disease and diabetes is increased by having an affected family member. People found to be at risk can be offered ways to prevent or detect these diseases early through lifestyle advice or disease screening. This project will develop and evaluate a family history questionnaire in preparation for a trial of family history screening and its impact on disease prevention.
An International Randomised Trial Of Low-dose Aspirin To Prevent Recurrent Venous Thromboembolism (INSPIRE)
Funder

Funding Amount
$1,989,986.00
Summary
Patients who develop venous blood clots or pulmonary embolism, without an underyling cause, are at very high risk of recurrence once anticoagulant treatment (warfarin) is discontinued. The international INSPIRE trial is assessing whether low-dose aspirin treatment (a simple and cheap alternative to warfarin) is effective and safe in preventing further blood clots. If proven effective, aspirin could potentially prevent thousands of patients worldwide from experiencing such events.

These patients are at very high risk of recurrence once treatment with warfarin is discontinued. Warfarin treatment is very effective to prevent recurrence but is inconvenient because it has to be very closely monitored with blood tests and also causes serious bleeding complications in a significant number of patients. There are currently no other treatments available to prevent recurrent thrombosis. Low-dose aspirin treatment offers a simple, inexpensive, and widely practicable alternative to warfarin but has not yet been proven to be effective for preventing recurrent thrombosis. This study will investigate the effectiveness and safety of aspirin to prevent recurrence in patients with unprovoked deep vein thrombosis or pulmonary embolism who have completed standard anticoagulation with heparin and warfarin. If proven to be effective, aspirin could potentially prevent thousands of patients from experiencing recurrent venous thromboembolism or fatal pulmonary embolism worldwide and also save millions of dollars in health care costs each year.Read moreRead less

Summary
Coronary heart disease is a leading cause of mortality, morbidity and medical costs in Australia. During the 1950's and 1960's, rates of coronary disease increased rapidly, then in the late 1960's they started to decline. This decrease has continued steadily for 30 years.

During the 1950's and 1960's, rates of coronary disease increased rapidly, then in the late 1960's they started to decline. This decrease has continued steadily for 30 years. While some other westernised countries have had this same experience, in Eastern Europe and in many developing countries coronary disease is increasing. There is a huge amount of evidence from experimental studies in animal and human subjects and population studies in many countries that the major determinants of coronary disease are high blood pressure, cigarette smoking and high cholesterol (and other lipids) as well as dietary factors, obesity and physical inactivity. Recently several large multicentre studies have found unexpectedly weaker associations between heart risk factors and disease rates. It is hypothesised that this is due to inappropriate analyses in which data from populations at different stages of the coronary epidemic have been combined. The aim of this study is to develop improved statistical methodology to help understand recent findings from large scale studies, such as the World Health Organization's MONICA Project, the US ARIC study and the Seven Countries study. It will provide new theoretical results and statistical software for their implementation. From a public health perspective the most important outcome will be clarification of recent apparently anomalous findings about the importance of established risk factors and effective treatments in reducing coronary disease at the population level.Read moreRead less
