Summary
The failure of bone prostheses is becoming a major health problem. More than 26,000 hip, and an equal number of knee, replacements were performed in Australia in 2002 with the number increasing between 5%-10% each year for the previous 10 years. Disturbingly, the incidence of revision hip surgery in Australia is now more than 15%, meaning that, despite the impressive success of joint replacement surgery, a significant number of arthroplasties fail. It is becoming more common for young, active in ....The failure of bone prostheses is becoming a major health problem. More than 26,000 hip, and an equal number of knee, replacements were performed in Australia in 2002 with the number increasing between 5%-10% each year for the previous 10 years. Disturbingly, the incidence of revision hip surgery in Australia is now more than 15%, meaning that, despite the impressive success of joint replacement surgery, a significant number of arthroplasties fail. It is becoming more common for young, active individuals to receive joint replacement surgery to improve their quality of life. This, combined with increasing life expectancy, and the known higher rate of failure of joint replacements in younger patients, means that the morbidity of a failed replacement, and the mobidity and associated mortality of revision surgery, will become an increasingly important health issue, with a major impact upon health budgets. The overwhelming majority of hip and knee prostheses have metal or ceramic on polyethylene bearing surfaces. It is now apparent that most implants fail due to bone loss around them leading to loosening, and evidence is accumulating that polyethylene wear particles are a major contributing factor to this process. It is therefore vital that we obtain better understanding of the causes of implant failure in order to extend the life of these implants and this project is designed to do so.Read moreRead less
Patterns, Pathways And Price Of Developing Disparities In Cardiovascular And Respiratory Health By Age 11-12 Years: The Longitudinal Study Of Australian Children

Summary
Cardiovascular and lower respiratory diseases are leading causes of death, show marked social gradients, and have origins in early life. We will measure cardiorespiratory health at age 11-12 years in the national Longitudinal Study of Australian Children. Combined with rich existing psychosocial and health data spanning the entire first decade, we will explore early-life mechanisms underlying emerging patterns of social disparity and their potentially-avoidable cost – evidence that is essential ....Cardiovascular and lower respiratory diseases are leading causes of death, show marked social gradients, and have origins in early life.

Combined with rich existing psychosocial and health data spanning the entire first decade, we will explore early-life mechanisms underlying emerging patterns of social disparity and their potentially-avoidable cost – evidence that is essential to develop new intervention strategies.Read moreRead less
