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

Coffin Bay (South Australia) is experiencing worsening environmental conditions despite its major economic and ecological importance. Research is needed to understand the cause of this decline, particularly in light of a recent bacterial outbreak that impacted the aquaculture industry. This multidisciplinary project aims to deliver world-leading scientific advice based on novel field techniques and innovative models of this complex inverse estuary system and its surrounding catchment. The new understanding of the sources, fluxes and fate of nutrients within the bay and the surrounding catchment, arising from this project, is expected to benefit management decision-making and establish a new standard in estuarine water quality investigation.Read moreRead less
Coverage with Evidence Development: Application to pharmaceutical reimbursement decisions. Some new medicines produce only a small improvement in health but have considerable costs. When these medicines are trialled on only small numbers of people, uncertainty results about the value of the medicine, which can create problems for decision makers. Funding medicines where there is uncertainty may lead to harm when medicines are later found to be unsafe, or waste millions of dollars when they are ....Coverage with Evidence Development: Application to pharmaceutical reimbursement decisions. Some new medicines produce only a small improvement in health but have considerable costs. When these medicines are trialled on only small numbers of people, uncertainty results about the value of the medicine, which can create problems for decision makers. Funding medicines where there is uncertainty may lead to harm when medicines are later found to be unsafe, or waste millions of dollars when they are overpriced relative to effectiveness. Not funding medicines may disadvantage patients in whom the medicines are effective. Methods to enable access to medicines while reducing uncertainty will offer significant benefit to patients, clinicians and taxpayers. Read moreRead less

Improving water quality modelling by better understanding solute transport. Poor stream water quality is a critical problem in Australia and globally. Stream water quality depends directly on pathways and time taken for water to transport pollutants through catchments. Predicting these pathways is highly challenging and currently requires specialised data. This project aims to better model the movement of water from rainfall to streams, enable greatly improved use of water quality data routinely ....Improving water quality modelling by better understanding solute transport. Poor stream water quality is a critical problem in Australia and globally. Stream water quality depends directly on pathways and time taken for water to transport pollutants through catchments. Predicting these pathways is highly challenging and currently requires specialised data. This project aims to better model the movement of water from rainfall to streams, enable greatly improved use of water quality data routinely collected in Australia's catchments and thereby better predict water quality behaviour. Proposed field studies aim to support this development. The outcomes sought are improved planning and management of water quality in our rivers, lakes and estuaries, improved health of these water bodies and improved water supplies.Read moreRead less
Health Impacts Of Sleep Apnea In Australian Men- A Longitudinal Population Study.
Funder
National Health and Medical Research Council
Funding Amount
$312,056.00
Summary
Obstructive sleep apnea (OSA) is very common, seen in 60-70% of men over 40 years old. OSA is linked to a number of serious conditions, e.g. heart disease and diabetes. However, we don't know which men are at risk of long term complications from OSA. Our aim is to follow-up men from a community sample of 1000 men who had sleep studies in 2010 to help identify who is at risk of poor health from OSA.

Funding Amount
$295,135.00
Summary
This collaboration involves the SA Health Department and community partners in analyses of local data from a 10-year biomedical cohort to (i) identify features of residential areas that are related to the metabolic syndrome and (ii) assess the mechanism by which area features influence metabolic syndrome through effects on behavioural and psychosocial mediators. The knowledge generated will inform policy intervention via urban planning and public health actions to support healthful lifestyles.
Funding our future: perceptions of the value of financial planning advice. This project will examine how perceptions of the value of financial planning advice are formed over time. If this is understood then both government and the industry can develop better strategies to encourage those who can benefit from financial advice to recognise and gain value from the service.
