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
Two hundred million people are infected with the Hepatitis C virus. There is no vaccine and the rate at which new strains of the virus arise enable it to evade the human immune system. This study aims to decipher how new viral strains are generated and transmitted, thereby enabling the development of new vaccines.

Summary
Each year about 12,000 Australians of working age survive a stroke. These younger survivors have responsibility for generating an income or providing care for families and state that their main objective is to return to work for financial reasons and to help rebuild confidence and independence. This observational 3 year study will determine thefactors are associated with returning to work, improving the wellbeing of thousands of stroke survivors and their families using multivariate regression.
Injecting Drug Users: Social Networks And Molecular Epidemiology Of The Hepatitis C Virus

Summary
The hepatitis C virus (HCV) continues to spread among injecting drug users (IDUs) in Australia at a very high rate, despite success in preventing the spread of HIV in the same groups; the complete reasons for this remain unclear. There is an urgent need for the HCV epidemic among IDUs to be contained. To do so, we must better understand the ways in which it is spreading among IDUs.

There is an urgent need for the HCV epidemic among IDUs to be contained. To do so, we must better understand the ways in which it is spreading among IDUs. Much is known about risk behaviours of individual IDUs and how they contribute to HCV transmission; much less is known about how these behaviours are modified by the influence of the IDUs peer group, especially their immediate and intimate social networks. Despite its importance in influencing attitudes and behaviours, and therefore HCV transmission, this has never been studied in Australia, nor, in relation to HCV, in the world. We hope that by studying social and risk networks of IDUs we shall discover new ways in which control of the HCV epidemic can be achieved in Australia. We intend to do this among two groups of young IDUs, one of Vietnamese ethnicity, located in the one suburb of Melbourne. By using field techniques for gathering information (ethnography), and sophisticated analytic techniques to understand how these networks are formed and influence behaviours, we hope to be able to identify interventions which work at the level of the social group rather than the individual in bringing about the behaviour change necessary to prevent HCV transmission. To ensure that the risk networks we describe are as influential as they appear, and to discover more about the variability of HCV, we will also be investigating the relationship between the various strains of HCV in members of the IDU networks, particularly as another measure of the connectedness of networks and network members. This will be done using sophisticated genetic analysis of the HCV obtained from network members by blood test.Read moreRead less
Adverse Outcomes Following Cataract Surgery In Western Australia: A Population Study Using Record Linkage

Summary
Cataract is a major cause of correctable visual loss with surgery the only treatment available. Cataract surgery is now one of the most commonly performed operations. With the ageing population, the number of operations is set to double within the next 12 years in Western Australia, from 10,000 procedures a year currently. Although surgery is successful in most cases, complications do occur.

Cataract surgery is now one of the most commonly performed operations. With the ageing population, the number of operations is set to double within the next 12 years in Western Australia, from 10,000 procedures a year currently. Although surgery is successful in most cases, complications do occur. Endophthalmitis (infection of internal structures of the eye), incomplete cataract removal, detachment of the retina and corneal decompensation (opacity of the clear front of the eye) are four major complications of cataract surgery. These complications may cause blindness and are expensive to treat. We propose to investigate these serious, potentially blinding, complications of cataract surgery by measuring how often these complications occur and to examine if changes in surgical technique over the past 20 years have resulted in better outcomes. We will also evaluate risk factors for endophthalmitis; and determine the quality of life and economic costs of endophthalmitis after cataract surgery. Our study findings will enable us to better inform eye surgeons, the general community, health policy makers and the scientific community about the cost versus safety of different forms of cataract surgery. Unless effective strategies can be found to reduce the rate of complications, the personal and community burden of these devastating complications will only increase as the number of operations continues to increase.Read moreRead less
Blue Mountains Cohort Study: Incidence Of Eye Disease, Hearing Loss And Other Health Outcomes

Summary
The proposed study aims to determine the cumulative 10-year incidence and progression of the major eye diseases that threaten vision in older Australians, including age-related maculopathy, cataract, glaucoma and diabetic retinopathy. The cumulative 5-year incidence of age-related hearing loss and prevalence of loss of smell will also be determined. The study will assess risk factors and associations with these diseases, using information collected at the baseline, 5-year and 10-year examination ....The proposed study aims to determine the cumulative 10-year incidence and progression of the major eye diseases that threaten vision in older Australians, including age-related maculopathy, cataract, glaucoma and diabetic retinopathy. The cumulative 5-year incidence of age-related hearing loss and prevalence of loss of smell will also be determined. The study will assess risk factors and associations with these diseases, using information collected at the baseline, 5-year and 10-year examinations on medical history, ocular factors, vascular disease, smoking, diet, plus environmental and blood factors. The study aims to assess the impact of these sensory impairments on measures of dependence, quality of life, general health, age-related cognitive impairment, depression and on mortality. The study will be conducted in Katoomba on the cohort of residents from two postcode areas who originally attended the Blue Mountains Eye Study during the period 1992-4. Examinations will commence by May, 2002 and be completed by April, 2004. We hope to examine 2,032 of the original cohort of 3,654 people. This project will build on the data already collected by the Blue Mountains Eye Study, one of the most successful community surveys conducted in Australia. The 10-year follow-up period will provide increased statistical power and precision to assess the role of possible risk factors for eye disease already identified by the earlier baseline and 5-year studies of this population. The hearing component of the study will provide the first longitudinal data on hearing loss from a large older Australian population.Read moreRead less
