Summary
This multi-factorial project will extend the follow-up of 4 large, established groups of people who have experienced significant exposure to asbestos, silica or diesel, either through their jobs, or environmentally. Mesothelioma, lung cancer and prostate cancer are common among these groups. The study will provide important information on the effects of different levels of exposure to these three cancer-causing agents, as well as their effects on chronic respiratory diseases such as asbestosis, ....This multi-factorial project will extend the follow-up of 4 large, established groups of people who have experienced significant exposure to asbestos, silica or diesel, either through their jobs, or environmentally. Mesothelioma, lung cancer and prostate cancer are common among these groups. The study will provide important information on the effects of different levels of exposure to these three cancer-causing agents, as well as their effects on chronic respiratory diseases such as asbestosis, silicosis, asthma and tuberculosis. Ways in which these diseases may be prevented through the diet and other lifestyle habits (including smoking, alcohol consumption and exercise), will be closely examined. This study will also help to identify the genes which may place some people at a higher risk than others.Read moreRead less
Interplay Of Genetic And Environmental Factors On Age-related Cataract Development

$217,519.00
Summary
We aim to investigate factors influencing the development of age-related cataract, using data collected from two population-based studies of older persons: the Blue Mountains Eye Study and the Beaver Dam Eye Study (USA). We will assess genetic susceptibility to the two common forms of age-related cataract, replicated in two Asian samples, and determine how genetic and environmental factors jointly contribute to the development of cataract in some older persons.
I am an epidemiologist, primarily interested in the study and quantitative assessment of the environment-health relationship. Specifically, my current research focuses on development of innovative methods to assess the impact of ecosystem change (eg, clim
Gene-environment Interactions In The Aetiology Of Myopia

Summary
The rapid rise in the prevalence of shortsightedness poses a major public health challenge. The Sydney Myopia Study has collected a large database on environmental risk factors, and has documented a major protective effect of children spending more time outdoors. Other studies suggest that myopia has a major genetic component. This study will collect DNA samples from over 4000 participants in the Sydney Myopia Study, and through genome-wide scanning, will look for gene-environment interactions.
The cornea is essential for vision. Corneal blindness affects all ages, and is often irreversible. Infection of the cornea is a significant cause of corneal blindness. Despite the development of wide-spectrum antibiotics, corneal infections are on the rise. The aim of this project is to provide up-to-date information on the range of bacteria causing corneal infections, their antibiotic sensitivities, and antibiotic prescribing patterns by the ophthalmic profession.
Epidemiological And Molecular Risk Factors For Diabetic Retinopathy Blindness.

Summary
Diabetic retinopathy (DR) is the leading cause of blindness in working age adults, affecting 30% of Australians with diabetes. Patients at most risk of blindness are the focus of this project. We aim to (1) investigate why some people are more likely to develop blinding DR by looking at genetic difference between diabetic patients with and without DR; and, (2) help to understand why Indigenous Australians are so over represented in this subset of diabetic patients going blind from DR.
Genome-wide Association Study (GWAS) For Juvenile-onset Myopia And Its Component Measures To Identify Molecular Pathways To Prevent Myopia

Funding Amount
$495,364.00
Summary
We will examine 2,000 young adults from the Western Australian Raine Cohort at the Lions Eye Institute / University of Western Australia. Ocular data will be collected relating to myopia (short-sightedness) and will be combined with extensive previous childhood and genetic research data collected on the Cohort, to investigate the genetic and environmental factors predisposing to myopia. This will assist in understanding the factors leading to myopia.
The Relationship Between Airborne Particle Exposure, Incident Respiratory Symptoms And Decline In Lung Function

Summary
Air pollution has been consistently identified as the environmental health problem of greatest concern to the general public in Australia. Yet hard evidence of adverse health effects from air pollution in Australian cities and towns is limited to date. It has been estimated that high levels of particles in urban air could be responsible for as many as 2,400 deaths nationally, costing approximately $4,300 million each year. This study will follow two groups of young Melbourne adults recruited som ....Air pollution has been consistently identified as the environmental health problem of greatest concern to the general public in Australia. Yet hard evidence of adverse health effects from air pollution in Australian cities and towns is limited to date. It has been estimated that high levels of particles in urban air could be responsible for as many as 2,400 deaths nationally, costing approximately $4,300 million each year. This study will follow two groups of young Melbourne adults recruited some years ago for studies of respiratory health. They will be a sent a questionnaire by mail and invited back to our laboratory for breathing tests. We will obtain routinely collected air quality data and measure fine particles < 2.5 thousandths of a mm in outdoor air. A subgroup of 100 subjects will also participate in some measurements of indoor air pollution. The analysis will look for relationships between particles in the air, new symptoms and changes in lung function over time. Comparisons will also made with other centres doing a very similar study in Europe. Reviews commissioned by the National Environment Protection Council have highlighted the lack of Australian data to assist in setting standards for particulate air pollution. The proposed study would provide some of the necessary local data and assist in the development of new health based environmental protection measures for fine particles. Once these measures have been implemented, we would expect to see an improvement in the respiratory health of the Australian population.Read moreRead less
