Summary
Multiple Sclerosis (MS) is a chronic autoimmune inflammatory disease of the brain and spinal cord that leads to various degrees of disability. The causes of MS are not yet known, and there is presently no cure. However, there is strong evidence that both an inherited susceptibility and environmental factors are important. This environmental case control study will be conducted in Tasmania and will run concurrent to a genetic project on MS which allows assessment of gene-environment interactions. ....Multiple Sclerosis (MS) is a chronic autoimmune inflammatory disease of the brain and spinal cord that leads to various degrees of disability. The causes of MS are not yet known, and there is presently no cure. However, there is strong evidence that both an inherited susceptibility and environmental factors are important. This environmental case control study will be conducted in Tasmania and will run concurrent to a genetic project on MS which allows assessment of gene-environment interactions. It focuses on infections, timing of childhood infections and long term sun exposure. It has been suggested that MS may be due to an immune disturbance following viral infection and that the timing of childhood infections may be initially important. Also, in Australia, there is a sevenfold increase in MS prevalence as one moves from Queensland to Tasmania. This latitudinal gradient might be due to ultra violet radiation, through an influence on immune function. Beside those main focuses, the study will include other environmental factors like chemicals, diet and vaccinations. Hopefully this project will contribute to a better understanding of the causes of MS, which are relevant for preventative strategies and devising optimal treatment.Read moreRead less

Building Australia's Capacity To Study Preventable Causes Of Common Diseases Through Epidemiological Research
Funder
National Health and Medical Research Council
Funding Amount
$2,500,000.00
Summary
This program of work will build Australia's capacity to study the preventable causes of common disease. Researchers will be trained to investigate the impact of genetic, environmental and lifestyle factors on disease in large samples of people. The diseases will include diabetes, cardiovascular disease, bone and joint conditions, some common cancers such as skin and prostate cancer, and diseases affecting the nervous system such as multiple sclerosis.
Preterm birth, a birth before the 37th week of pregnancy occurs for fewer than 8% of mothers but is associated with two-thirds of all fetal deaths and deaths of liveborn infants in the first month after birth. In the late 1990s those deaths are concentrated among very preterm births i.e. births before the 32nd week of pregnancy. Infants born very preterm are very likely to need neonatal intensive care, quite likely to have had major respiratory, infectious or other problems after birth, and to n ....Preterm birth, a birth before the 37th week of pregnancy occurs for fewer than 8% of mothers but is associated with two-thirds of all fetal deaths and deaths of liveborn infants in the first month after birth. In the late 1990s those deaths are concentrated among very preterm births i.e. births before the 32nd week of pregnancy. Infants born very preterm are very likely to need neonatal intensive care, quite likely to have had major respiratory, infectious or other problems after birth, and to need readmission to hospital in the first year after birth. Surviving infants are more likely to have major impairments, minor impairments, and school difficulties than infants born at term. There is a substantial impact on families, health services and society of very preterm birth.There has been no reduction in the proportion of births which are preterm, or very preterm in the last 20 years, though advances in treatment and care have markedly improved the survival of preterm and very preterm infants. This study will investigate the role of previous pregnancies which did not result in births (miscarriages and terminations), together with other procedures such as D and C (dilatation and curettage), in subsequent preterm birth. As these previous pregnancy losses are all fairly common experiences any associated risk is important and this particular factor has not been studied in this way before. There is preliminary evidence that they may be associated with preterm birth and the study will be able to measure the associations while taking into account all the other known risk factors. Other possible risk factors such as experiencing violence in pregnancy or social factors acting at a neighbourhood level will also be included. If it is found that previous pregnancy losses are independently associated with preterm birth it will be possible to develop and test preventive strategies.Read moreRead less
Trials To Prevent The Transmission And Complications Of Sexually Transmitted Infections, Including HIV

Funding Amount

Summary
Sexually transmitted infections (STIs) are important causes of illness in some sectors of the community. Even though they can be effectively prevented and treated, many health services do not give them priority. This research project will study ways in which general practitioners can better diagnose and treat STIs. We will carry out trials that compare new approaches to supporting doctors in this area, that involve a mixture of training, reminders and technical support as needed.
This study will follow up over 12,000 men aged 65-83 years who have previously completed a questionnaire about their medical, social, family and occupational history and lifestyle and have undergone a simple physical examination (height, weight, waist, girth at the hips and blood pressure). The first aim is to determine which of these factors predicts serious ill-health from heart disease, stroke and certain cancers in old age. In addition, we will test the hypothesis that risk factors for heart ....This study will follow up over 12,000 men aged 65-83 years who have previously completed a questionnaire about their medical, social, family and occupational history and lifestyle and have undergone a simple physical examination (height, weight, waist, girth at the hips and blood pressure). The first aim is to determine which of these factors predicts serious ill-health from heart disease, stroke and certain cancers in old age. In addition, we will test the hypothesis that risk factors for heart disease also predict the development of dementia because it seems that part of dementia in some patients is explained by their having suffered multiple small strokes. Finally, we will examine the relationship between development of dementia and previous major surgery as there is growing evidence that major surgical operations in older patients can be followed by confusion and impairment of thinking that may never recover fully. The overall aim is to discover preventable factors for several of the leading causes of ill-health in old age.Read moreRead less
Metabolic Syndrome, Inflammation And Non-alcoholic Fatty Liver Disease In Busselton

Summary
The metabolic syndrome is a clustering of obesity, insulin resistance, high cholesterol and high blood pressure. It could affect up to 30% of the population and often leads to diabetes and heart disease. Fatty liver disease is a chronic liver condition that often has no symptoms but can lead to serious liver damage. It could affect up to 25% of the population and is common even in people who drink very little alcohol. The rising prevalence of obesity in Australia suggests that the metabolic synd ....The metabolic syndrome is a clustering of obesity, insulin resistance, high cholesterol and high blood pressure. It could affect up to 30% of the population and often leads to diabetes and heart disease. Fatty liver disease is a chronic liver condition that often has no symptoms but can lead to serious liver damage. It could affect up to 25% of the population and is common even in people who drink very little alcohol. The rising prevalence of obesity in Australia suggests that the metabolic syndrome and fatty liver disease may be on the increase and therefore so too could diabetes and heart disease which already consume significant health resources. Using the unique health data collection of the Busselton Health Study in Western Australia, this project will help to determine how common these conditions are in Australia and lead to a better understanding of the nature and causes of these conditions including the possible role of chronic inflammation. This important information will be used to provide opportunities for better risk assessment, disease prevention, and earlier intervention.Read moreRead less
