Summary
Both depression and osteoporosis are common, debilitating and expensive diseases and there is research to suggest that these conditions are related. This study will examine a potential common mechanism, inflammation, which may underlie both diseases. It will focus on circulating proteins which are associated with both depression and fragility fractures, and examine the role they play in both disorders.

Summary
Severe depression is characterised by slowing of mental and motor abilities. Previous research by our group indicates the role of small frontal and basal brain regions in the regulation of these abilities. This research will extend our previous studies by providing new information detailing the underlying physiology of behavioural and structural abnormalities in patients with severe depression. Emerging research by our group and others suggest that some types of severe depression in later life a ....Severe depression is characterised by slowing of mental and motor abilities. Previous research by our group indicates the role of small frontal and basal brain regions in the regulation of these abilities. This research will extend our previous studies by providing new information detailing the underlying physiology of behavioural and structural abnormalities in patients with severe depression. Emerging research by our group and others suggest that some types of severe depression in later life are due to undetected forms of cerebrovascular disease. If we are able to demonstrate that the key features of severe depression of this type (psychomotor, attentional, memory and executive disturbance and global disability) are related to such brain changes this may lead to a major breakthrough in the prevention and treatment of these disorders. A new type of brain imaging technology called 'functional Magnetic Resonance Imaging' (fMRI) permits simultaneous investigation of the structure and function of small areas of the brain. As the technique does not use radiation and can be performed while the patient is completing mental tasks, it can be used in repeated experiments. Consequently, it permits description of brain changes (areas of activation) that occur during specific mental tasks. Therefore, if we are now able to use this technique to extend our previous clinical and imaging studies we will be able to test whether some forms of late-life depression are due to undetected brain changes.Read moreRead less

Summary
Over the past 20 years, studies have highlighted the possible roles of stressful life events and distress, possibly mediated by social support and personality, in causing or speeding up the development of breast cancer. This possibility is of strong concern to consumers. To date, there have been few well designed, prospective studies of this issue. Furthermore, no previous studies have specifically targeted women at increased risk because of their family history.

This possibility is of strong concern to consumers. To date, there have been few well designed, prospective studies of this issue. Furthermore, no previous studies have specifically targeted women at increased risk because of their family history. Over the past 7 years, it has become possible to identify 2 breast cancer genes (BRCA1 and BRCA2). Female carriers of mutations in these genes with a strong family history have an estimated lifetime risk of between 35% and 85%. The Kathleen Cuningham Consortium for Research into Familial Breast Cancer (KConFab) was established 7 years ago to coordinate the collection of genetic, epidemiological and clinical data in Australian families with a dominantly inherited predisposition to breast cancer. Due to the high rate of breast cancer diagnoses in this group, and the systematic recruitment of large numbers of high risk women by KConFab, there is a unique and temporary opportunity to conduct a rigorous study to resolve this question, with sufficient numbers involved. The study is a world first, and will provide the best data to date in this area. If the study demonstrates a relationship between psychosocial factors and the development of breast cancer in women from high risk breast cancer families, subsequent identification of vulnerable individuals and the implementation of appropriate interventions may have a real impact on reducing morbidity and mortality in this population. Furthermore, the results may have implications for all women in reducing breast cancer incidence.Read moreRead less

To date there has been little prospective assessment of psychosocial factors in the development of breast cancer. Furthermore, no research in this area has specifically targeted women at increased risk because of their family history, nor explored whether the impact of psychosocial factors systematically varies according to genetic mutation status. Over the past 5 years it has become possible to isolate two breast cancer genes (BRCA1 and BRCA2). Female carriers of mutations in these susceptibility genes have an estimated lifetime risk of breast cancer of between 37% and 85%. The Kathleen Cuningham Consortium for Research into Familial Breast Cancer (KConFab) was established four years ago to co-ordinate the collection of genetic, epidemiological and clinical data in Australian families with a dominantly inherited predisposition to breast cancer. The systematic recruitment of large numbers of high risk women by KConFab provides a unique and temporary opportunity to address questions concerning psychosocial predictors of disease development in a prospective design with sufficient power, due to the higher rates of breast and ovarian cancer events in this population. We will also be able to explore interactions with genetic mutation status. The study will be a world first, and provide the most rigorous data to date in this area. If this study demonstrates a relationship between psychosocial factors and the development of breast cancer in women from high risk families, subsequent identification of vulnerable individuals and the implementation of appropriate interventions may have a real impact on reducing morbidity and mortality in this population. Furthermore, the results may have implications for all women in reducing breast cancer incidence.Read moreRead less
