Summary
Cancer is still the commonest disease causing death in chilhood. Childhood neuroblastoma is a cancer of the nerve tissue which presents usually as a widely spread malignancy, which responds poorly to conventional therapy, indicating the need for novel treatment approaches. Vitamin A derivatives, or retinoids, given in addition to conventional therapy improves the cure rate for children with advanced neuroblastoma to 50%. We have shown that one likely mechanism of retinoid resistance is a deficie ....Cancer is still the commonest disease causing death in chilhood. Childhood neuroblastoma is a cancer of the nerve tissue which presents usually as a widely spread malignancy, which responds poorly to conventional therapy, indicating the need for novel treatment approaches. Vitamin A derivatives, or retinoids, given in addition to conventional therapy improves the cure rate for children with advanced neuroblastoma to 50%. We have shown that one likely mechanism of retinoid resistance is a deficiency of retinoic acid receptor beta, which is a necessary factor in the neuroblastoma cell for converting the retinoid anti-cancer signal into an irreversible cellular change. In this project we will define why some neuroblastoma cells express low levels of this protein and test new retinoid therapies.Read moreRead less

Summary
Obesity is a serious public health problem in Australia. The rate of obesity appears to be rising. Currently 19-23% of children and adolescents are overweight or obese. Adolescence is a critical period for the development of obesity in both males and females. It is a time when new dietary habits, likely to promote fatness, are adopted and physical activity declines. Understanding the factors that drive these behaviours is essential for effective prevention of obesity and related diseases. In 199 ....Obesity is a serious public health problem in Australia. The rate of obesity appears to be rising. Currently 19-23% of children and adolescents are overweight or obese. Adolescence is a critical period for the development of obesity in both males and females. It is a time when new dietary habits, likely to promote fatness, are adopted and physical activity declines. Understanding the factors that drive these behaviours is essential for effective prevention of obesity and related diseases. In 1996-7, our research group studied a group of over 400 children who were aged 7-8 years, were living in western Sydney and were born at Nepean Hospital. In our new study, we plan to re-study this group of children, now in early adolescence. This will allow us to assess the family and environmental factors influencing physical activity and eating behaviour at the beginning of adolescence. The aims of our study are to: Measure changes during early adolescence in eating and physical activity behaviours that are likely to increase obesity risk Measure anthropometric and biochemical markers for future risk of type 2 diabetes and cardiovascular disease in both adolescents and their parents Identify factors in the family environment that influence changes in food intake and physical activity in early adolescence The study will be done in two phases, 18 months apart. The measurements will be done in the study centre at Nepean Hospital in western Sydney. We will measure the height, weight and skinfold thickness of the adolescents and, if possible, their parents. We will also ask the young people and their parents to complete questionnaires about the family food and activity environment and their level of physical activity and food intake. In addition, the adolescents will wear a light-weight activity monitor for 3 days ( to measure the level of activity), blood pressure will be measured and cholesterol and blood sugar levels checked.Read moreRead less

Summary
Type 1 diabetes is one of the most common chronic diseases of childhood. The burden of disease on the individual, their family and the community is enormous. The goal of this fellowship is to utilise evidence-based research to inform health policy and enhance the care of young people with diabetes. The proposal addresses patterns of disease in Australia, environmental triggers for diabetes, and care of the young person with diabetes through implementation of national evidence based clinical care ....Type 1 diabetes is one of the most common chronic diseases of childhood.

The goal of this fellowship is to utilise evidence-based research to inform health policy and enhance the care of young people with diabetes.
