Summary
Breast cancer is the most common cancer in Australian women and there have been a number of recent events which have raised public concern that occupational exposures are contributing to the increasing occurrence of this cancer. In this study, we will investigate occupational causes of breast cancer, particularly shift work, industrial solvent use and combustion products. We will compare occupations of 1000 women with breast cancer and 2000 women without cancer.

A principal objective is to collect exposure data on acne and digit ratio, and genotype cases and controls across the studies of the Prostate Cancer Program for common genetic variants in 4 candidate genes in the hormonal pathway. The established risk factors for prostate cancer are only age, race and family history. We anticipate that this project will cast light on the role of hormones in prostate cancer and that we will identify new markers of risk of prostate cancer and markers of disease aggressiveness. These outcomes will help us identifying men who are at risk for prostate cancer to target screening and surveillance, and plan prevention strategies. Furthermore, they will also form the basis for research on treatment targets.Read moreRead less

Summary
Glaucoma is a common cause of loss of vision worldwide but we are unable to predict which people are at high risk of blindness. We aim to discover the genetic risk factors for glaucoma. We will use cutting edge genetic technology to assess the whole genome in thousands of patients with glaucoma. We hope to identify important new glaucoma genes, which could lead to the development of diagnostic tests and treatments which will provide the most cost-efficient ways to prevent glaucoma blindness.

Summary
Breast density is a well established risk factor for breast cancer, and has been shown to be reversibly influenced by hormone exposures in adult life. As one of the important roles of sex hormones during puberty is mammary cell proliferation, it is plausible that exposures at this earlier life stage might have a sustained influence on breast tissue composition and density, and subsequent breast cancer risk. This project aims to increase our understanding of the influence of sex hormones in adole ....Breast density is a well established risk factor for breast cancer, and has been shown to be reversibly influenced by hormone exposures in adult life. As one of the important roles of sex hormones during puberty is mammary cell proliferation, it is plausible that exposures at this earlier life stage might have a sustained influence on breast tissue composition and density, and subsequent breast cancer risk. This project aims to increase our understanding of the influence of sex hormones in adolescence on breast cancer risk by testing the hypothesis that exposure to large doses of sex hormones during adolescence has long-term effects on mammographic density. This will be done by comparing the mammographic densities of women who were treated with high doses of estrogen for tall stature during adolescence with women who were similarly assessed for tall stature but not treated. No previous study in humans has examined the long-term effects on breast tissue of high dose estrogen exposure at this early life stage. This is not surprising, given the difficulty in finding a suitable exposed population. This cohort of women, assessed or treated for tall stature, provides us with a unique opportunity to examine these influences. This research will add to our understanding of the influence of sex hormones in adolescence on mammographic density and breast cancer risk. If hormonal factors in adolescence are shown to influence mammographic density, this may lead to new avenues for breast cancer prevention efforts that are targeted much earlier in life. This information may lead to new research directions examining adolescent hormonal exposures (both endogenous and exogenous) and their influence on breast tissue.Read moreRead less
Evaluation Of An Instrument For Management Of Behavioural And Psychological Symptoms Of Dementia.

Summary
Behavioural and Psychological Symptoms of Dementia (BPSD) distress the patient and others. The behaviours, and not the underlying causes, are often treated with antipsychotics, despite side effects and low efficacy. An assessment instrument for care staff to determine and address causes of BPSD will be implemented. We predict training will reduce inappropriate prescribing and other reasons for distress. Where medication is required, detailed information will assist more targeted prescribing.
TELEPHONE COUNSELLING FOR MAINTENANCE OF PHYSICAL ACTIVITY, WEIGHT LOSS And GLYCAEMIC CONTROL IN TYPE 2 DIABETES

Summary
Regular exercise, a healthy diet and weight loss are key to managing type 2 diabetes, yet these are major challenges for most people with diabetes. This study will evaluate the impact of a telephone counselling program to assist people with type 2 diabetes to exercise, eat a healthy diet and lose weight, with the goal of helping them to sustain these changes over the long-term. It is expected that these lifestyle changes will also result in improved blood glucose control and quality of life.

Over the past 9 years our team has conducted a follow-up study of a large group of 111 Australian children and adolescents with autism. The young people have continued to have very high levels of emotional and behavioural disturbance and generally do not improve. Parents of children with autism are under significant amounts of stress; reporting high levels of disturbed family functioning and mental health problems. Although there is no cure, children benefit most when early help is provided (under 5 years). There are several promising interventions based on intensive behaviour and educational management, for example requiring 40 hours per week of therapist contact over 2 years. Such programs are costly and impractical as widely available treatment options. Training parents to understand and manage their child also shows promise. This study will evaluate the effectiveness of a parent skills training and education treatment program compared to supportive therapy, and to generally available community services. The therapists will follow a treatment manual that will ensure a consistent and replicable approach. The progress of the children with autism and their families will be reassessed immediately after treatment, and at 1 and 2 years post-treatment in order to ascertain immediate and long-term effects of the treatment. If treatment proves to be of use, we will have established a defined, cost efficient, practical and effective model of early treatment that can be easily taught to professionals and widely disseminated throughout early childhood services.Read moreRead less

Summary
For people with type 2 diabetes (T2DM) it is essential that blood glucose levels are managed well to reduce the risk of developing complications. Physical activity is essential for maintaining glucose levels because it helps make the muscles use glucose more effectively. In particular, being active through strength training not only improves blood glucose levels, but can be very effective for maintaining good physical functioning, which is known to be reduced by having T2DM. This study builds on ....For people with type 2 diabetes (T2DM) it is essential that blood glucose levels are managed well to reduce the risk of developing complications. Physical activity is essential for maintaining glucose levels because it helps make the muscles use glucose more effectively. In particular, being active through strength training not only improves blood glucose levels, but can be very effective for maintaining good physical functioning, which is known to be reduced by having T2DM. This study builds on our earlier research which demonstrated significantly improved blood glucose levels from a strength training program for older adults with T2DM. The strength training program is to be administered nationally in a research to practice trial (Lift for Life); however, the original research found that those who did not complete the program as it was intended (ie, poor adherence) did not show significant improvements in blood glucose levels. Furthermore, maintenance of strength training exercises after completion of the program was poor and resulted in return of blood glucose levels back to pre-starting levels. In people without diabetes, we have collected pilot data that shows that the use of behavioural strategies based on behavioural theories whereby each person's motivations and barriers are taken into consideration is more effective than the traditional one-treatment-fits-all approach. This study will evaluate the effectiveness of using behavioural strategies for improving adherence and maintenance to the Lift for Life strength training program (Enhanced L4L) for older adults with T2DM compared with the Standard L4L program. It will also follow-up participants 6 months later to determine the extent to which the changes in behaviour can be maintained. The study will provide information that will assist in the design, delivery and uptake of programs to improve treatment strategies in older adults with T2DM through the maintenance of healthier behaviours and lifestyles.Read moreRead less

Summary
We will use ocular motor technology to investigate motor dysfunction in autism and Asperger's disorder, to advance our understanding of the neurobiological bases of these disorders. This will help clarify whether neural networks are differentially disrupted in these disorders, as our previous clinical research suggests. This dissociation and the subsequent development of an ocular motor clincal screen may improve diagnosis, and potentially treatment, of these devastating conditions.
