Summary
It is essential to elucidate the underlying cause(s) of osteoarthritis because our current level of understanding of this condition has failed to produce effective treatments. Lesions in the bone under the cartilage (BMLs), seen using MRI, have strong potential value for the objective monitoring and management of OA. However, because the nature of BMLs is not well understood, the aim of this application is to perform a comprehensive study of BMLs in OA bone.
We will seek to address an important clinical problem in orthpaedics, namely the bone loss that commonly occurs around joint replacement prostheses. Termed peri-prosthetic osteolysis (PO), this bone loss can result in the loosening and ultimate failure and need for revision of the artificial joint components. PO is thought to be caused by the body's reaction to wear particles generated from the articulating surface of the prosthesis. However, it has not previously been possible to accurately exp ....We will seek to address an important clinical problem in orthpaedics, namely the bone loss that commonly occurs around joint replacement prostheses. Termed peri-prosthetic osteolysis (PO), this bone loss can result in the loosening and ultimate failure and need for revision of the artificial joint components. PO is thought to be caused by the body's reaction to wear particles generated from the articulating surface of the prosthesis. However, it has not previously been possible to accurately explore the relationship between prothesis wear and PO, or the progression of PO, because of a lack of techniques to image and measure the volume of PO around metal prosthesis components. We have developed a means to accurately and reproducibly measure the volume of bone loss, using CT, and will do so longitudinally in joint replacement patients to obtain the first information about the progression of PO. New computer based methods will be used concurrently to relate prosthesis wear and migration parameters to PO. Patients who come to surgery for replacement of failed prostheses will be investigated further by analysis of the tissues involved in the bone loss around prostheses. Basic science experiments will seek to understand the underlying causes of PO and the findings will be important in interpreting the clinical results. An animal model will be used to seek approaches to inhibiting the pathological response to wear particles. The significance of these studies is that they will lead to improved outcomes for joint replacement patients, increasing the interval to revision surgery, which is both extremely costly and brings an attendant morbidity and mortality.Read moreRead less

This project aims to investigate the sociological dimensions of antibiotics consumption by examining the views and experiences of clinicians, decision-makers, and members of the general population. The project expects to generate new knowledge about the social aspects of antibiotics use and consumer-provider interactions. Expected outcomes of this project include stronger consumer-provider collaborations about antibiotic use and a new evidence-base to guide policy decisions. This project should provide significant benefits for the national response to antimicrobial resistance, including enhanced public education and public policy.Read moreRead less
The Role Of Osteocytes In Particle Induced Osteolysis

Summary
Hip replacements often fail due to the loss of adjacent bone. Metal or polyethylene particles are produced as the prosthesis bearing surface wears but how do these particles lead to bone loss? Our work suggests involvement of osteocytes within the bone mineral, which are increasingly understood to drive bone physiology and pathology. We will explore the role of the osteocytes by examining their response to particles, which may identify a new target to prevent particle-induced bone loss.
Meals on Wheels: building towards a new social experiment for our times. This project contributes directly to the National Research Priority, promoting and maintaining good health: ageing well, ageing productively, through developing evidence-based knowledge on which to build future volunteer business models.

This project contributes directly to the National Research Priority, promoting and maintaining good health: ageing well, ageing productively, through developing evidence-based knowledge on which to build future volunteer business models. With the rapid ageing of the Australian population, it is imperative that volunteer-based organisations, such as Meals on Wheels, innovate to continue to deliver essential community services in a sustainable and cost-effective way. Meals on Wheels is integral within community care for frail, older people and those with disabilities, keeping people in their own homes and out of institutional care. Using national and international examples, the research has the potential to be adopted by the broad community services sector in Australia.Read moreRead less
Confronting everyday harms: preventing abuse of people with disability. The findings of the Disability Royal Commission necessitate new approaches to prevent violence, abuse, neglect and exploitation. Framed by recognition theory, this project proposes empirical research with young people with cognitive disability, using a new concept of ‘everyday harms’ in their paid relationships. The results will inform early responses to poor quality interactions in disability support. The strategic alliance ....Confronting everyday harms: preventing abuse of people with disability. The findings of the Disability Royal Commission necessitate new approaches to prevent violence, abuse, neglect and exploitation. Framed by recognition theory, this project proposes empirical research with young people with cognitive disability, using a new concept of ‘everyday harms’ in their paid relationships. The results will inform early responses to poor quality interactions in disability support. The strategic alliances with the government, industry and community partners will develop a practice framework to prevent everyday harms and the escalation to abuse, and to promote safety and wellbeing. The research has policy benefits for capacity-building in the sector to act on the rights and voices of people with disability. Read moreRead less

This project aims to research the use of performance and image-enhancing drugs (PIED), to understand the associated social practices and to assess what health information PIED injectors need. PIEDs use is increasing in Australia and is associated with serious health issues, including the transmission of blood-borne viruses, especially hepatitis C (HCV). Little is known about PIED injecting and the nation's harm reduction framework is unprepared to meet the problems it poses. This project expects to directly inform policy and practice, potentially averting an epidemic of HCV in this population, and aims to minimise HCV transmission among people who inject PIEDs.Read moreRead less

This Project aims to investigate drinking cultures among nurses and lawyers – two sizeable Australian workforces where heavy drinking is common. Addressing drinking cultures among social groups is an emerging strategy to complement population and individual level efforts to reduce alcohol-related harm. Alcohol use among workers has implications for health, safety and performance, yet researchers have paid little attention to occupational drinking cultures. Using rigorously collected qualitative and quantitative data, this Project expects to generate new knowledge on sociocultural practices and meanings of drinking in the groups, illuminate relations between drinking cultures and harms, and enable innovative intervention opportunities.
