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.
Long-term Effects Of Very Low Energy Diet Versus Conventional Diet On Adiposity, Lean Body Mass, Muscle Strength And Bone Density In Obese Adults, And Mechanisms Promoting Changes

Summary
Very low energy diets (VLEDs) are increasingly used to treat obesity. Of concern is the fact that VLEDs induce adaptive responses that can inhibit loss of – and promote regain of – fatness (particularly belly fat) while decreasing lean body mass, muscle strength and bone density. This project will therefore determine whether VLEDs could have negative effects on body composition that increase the risk of metabolic disease, sarcopenia or osteoporosis, and if so, what are the mechanisms involved.
Femoroacetabular impingement (FAI) is a common cause of hip pain characterised by extra bone formation at the hip, called a cam-deformity. FAI is thought to create hip joint damage and osteoarthritis. Our 5 year longitudinal study of people with FAI in two (Melbourne and Brisbane) sites will investigate whether factors (such as cam-deformity size, hip contact force, muscle strength and joint range) can predict hip joint damage (measured with magnetic resonance imaging) over two years.
BRAIN Training Trial: Balance, Resistance, Or INterval Training Trial: A Randomised Controlled Trial Of Three Exercise Modalities In Mild Cognitive Impairment

Summary
About 10% of older adults have mild changes in memory or thinking (Mild Cognitive Impairment, or MCI) which don’t interfere with daily life, but increase the risk of dementia. Exercise may improve thinking abilities, but the best kind of exercise is not clear. We will randomise 530 older adults with MCI in Australia, Canada, and Israel to weight lifting, high intensity aerobic training or toning exercises for 12 months to see which prescription is best for brain health and overall function.
Functional Electrical Stimulation Assisted Cycling (eStimCycle):A Novel Intervention To Improve Outcomes In The Critically Ill

Summary
The legacy of critical illness leaves millions of survivors worldwide with long lasting deficits in physical and brain function as well as anxiety, depression and post-traumatic stress disorder. Early rehabilitation may prevent or minimise these effects. This study evaluates the effectiveness of functional electrical stimulation of muscles with assisted in-bed cycling (eStimCycle) on muscle bulk, strength, physical and brain function at hospital discharge, 6 and 12 months.
Identification Of Novel PTH Anabolic Targets In Osteoblasts

Summary
Osteoporosis is a major disease affecting Australians. Whilst there are a number of drugs available that will reduce bone loss, there are few drugs available that build new bone, and little is known of the action of these drugs. New targets have been identified that modulate bone formation, and this project aims to validate these in appropriate models and determine their mechanism of action.
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.
Determining The Influences Of Cell Stress And Heat Shock Factor-1 Action In Osteoclast Formation And Pathological Bone Loss.

Summary
Cancer and rheumatoid arthritis cause painful bone destruction. This occurs due to increased numbers of bone destroying cells called osteoclasts. We found stress responses in bone cells can increase osteoclast numbers by activating proteins inside the bone cells that encourage osteoclasts to form. We will thus study whether cell stress blocking drugs might stop bone loss. As arthritis and cancer both cause stress responses, this work could identify a new way that such diseases affect bone.
Sclerostin: A Key Regulator Of Bone Mineralisation And Bone Catabolism

Summary
The regulation of bone mass is critical for many areas of human disease including osteoporosis, osteoarthritis, inflammatory bone loss conditions, e.g. rheumatoid arthritis, cancers of bone and problems relating to orthopaedic prosthesis failure. The osteocyte, the most abundant bone cell, plays a central role in normal bone biology and is likely key to these diseases. Sclerostin is one osteocyte product that may be a key to understanding how boneÍs mass and composition is controlled locally.
Furin: Carving-up Vital Substrates For Bone Remodelling And Homeostasis

Funding Amount

Summary
Osteoporosis, or porous bone, is a disease characterized by low bone mass and structural deterioration of bone tissue, leading to bone fragility and an increased susceptibility to fractures. It is caused by an imbalance between the cells that are constantly reabsorbing and reforming bone. The proposed project will address furin as a novel regulator of bone remodelling.
