Summary
Musculoskeletal conditions affect over 6 million Australians and research has shown that genetic background strongly influences development of these disorders. This project will identify genes that have a role in controlling bone and joint architecture. Identification of these genes will assist in the development of treatments targeting bone disorders and allow screening for these genes to provide an opportunity for people to take preventative action to improve bone and joint health.
Effect Of Bisphosphonates On Bone Architecture And Glucose Metabolism In Men With Prostate Cancer Receiving Androgen Deprivation Therapy: A Randomised Controlled Trial

Summary
Androgen deprivation therapy (ADT) is a type of hormonal treatment which is effective for prostate cancer treatment. However, ADT may cause bone fragility, weight gain, diabetes and heart disease. We will examine the effects of a bone strengthening treatment on bone structure and glucose metabolism in men receiving ADT. This trial should help in better define the risk benefit ratio of ADT, and therefore provide treating doctors with better guidance as to when and how to use this therapy.
Menopause is one of the important risk factors for bone loss, structural decay and bone fragility. We aim to quantify the biochemical, microstructural and biomechanical basis of loss of bone strength during and after menopause. A cohort of 324 pairs of female-female twins aged 25 to 75 years old will be followed up for up to 9 years. Defining the structural basis of bone fragility provides a rational means to identifying women at risk for fracture.
Fractures And Bisphosphonates: Reviving Osteoporosis Treatment Uptake By Identifying The Genetic, Material, And Microstructural Risk Factors Of Atypical Femur Fractures.

Summary
Atypical femoral fractures (AFF) are uncommon, but catastrophic, complications of antiresorptive osteoporosis treatments including bisphosphonates. We will identify patients at risk of AFF by determining changes in their bone structure and quality, and identifying genes that increase the risk of these fractures. In this way, cheap and effective antiresorptive treatments can be targeted to patients at the lowest risk of AFF and alternative treatments to those at highest risk.
Optimising Bone Regeneration Using Advanced Design And Fabrication Technologies

Summary
The aging population has produced a rapidly increasing demand for synthetic implants that can regenerate lost or diseased bone. This project will produce an implant that represents a viable alternative to bone autografts and allografts with broad applications for the repair of large or challenging bone defects. Such an achievement will have significant healthcare benefits by reducing patient morbidity and recovery time, and improving long-term outcomes.
In men, oestrogen may be important for strong bones and maintaining a healthy weight. Men with prostate cancer are given medical castration treatment to decrease testosterone, because testosterone is required for prostate cancer growth. Because oestrogen is derived from testosterone, they also have very low oestrogen levels. We want to conduct a trial in these men to find out whether giving back oestrogen will prevent bone loss and weight gain, among other health benefits.
Determining The Contribution Of Orexin Receptor Subtypes To Sleep Architecture

Summary
Sleep is an essential process that follows a regular pattern every night. The brain orexin system is a promising new target for sleep-inducing drugs; however it is not clear how best to manipulate this system to reproduce the cycles of sleep necessary to receive all the benefits sleep has to offer. This project will elucidate the contribution of the different components of the orexin system to the characteristics of sleep. This will facilitate the development of better treatments for insomnia.
Monitoring Bone Loss And Response To Therapy Through Bone Material And Structural Composition

Summary
Millions of scripts are filled for treatment of osteoporosis. However, there is no way of knowing if these drugs are right for these individuals, if it improves bone strength or are actually doing harm. Bone density measurement is of limited value. We have developed a new analysis method that measures changes in bone structure that tell us if the treatment is or is not working so alternative treatment can be used. The aim of this study is to test this new method.
