Every year >64,000 osteoporotic fractures occur, which is one every 8.1 minutes and women are three times as likely to have the disease than men. The Bone and Calcium Research Group at the University of Western Australia, has been monitoring a cohort of elderly women for since 1998. This study is called the Calcium Intake Fracture Outcome Study or CAIFOS. 1,500 women were recruited to study whether a daily calcium supplement for 5 years helps to prevent fractures compared to a diet without a supplement. Each year the study participants are reviewed and asked whether or not they have broken any bones and have other measurements to monitor their bone and cardiovascular health and cognitive function. The subjects will end the treatment phase in 2003 and they will find out the results of the study. More than 93% are interested in being followed for a further 5 years, where they will be contacted every 6 months and asked questions about their general health including information on fracture, hospital visits and changes in medication use. The subjects will have a clinic visits at 2 and 5 years post treatment. With the ongoing collection of adverse event data and metabolic and environmental data from the first phase of the study, we will be able to examine the metabolic and environmental factors that influence musculoskeletal, cardiovascular and mental health. This is important to determine how we can prevent disease to maintain the quality of life and independence in the elderly, a growing segment of the population.Read moreRead less
Neurocognitive Studies Of Reward Sensitivity In Opiate Addiction And Its Influence On Addiction-related Behaviour

Funding Amount
$258,275.00
Summary
Drug abuse is the greatest single preventable risk factor for physical illness and death in Australians . Our understanding of the neural and cognitive mechanisms that contribute to the transition from drug use to addiction is not yet complete. The current proposal investigates cognitive control dysfunction, most notably the impulsivity for reward seen in drug addiction that is known to predict the transition from drug use to addiction and relapse during treatment.
Investigating Cortical Plasticity And Connectivity In People With Chronic Low Back Pain And Controls Using Combined TMS_EEG

Summary
Little is known about the factors that predispose the development of chronic low back pain or what changes underpin effective treatment. Brain changes, thought to reflect adaptive processes are associated with chronic pain, but the extent of their contribution to CLBP is unknown. By measuring the adaptability of brain changes in people with CLBP I will determine if they differ from healthy controls in a way that predisposes them to develop chronic pain and is related to treatment response.
ASPREE- NEURO; Aspirin And Cerebral Microhaemorrhages

Summary
Cerebral Microhaemorrhages (CMH) are tiny areas of blood vessel breakdown commonly found on brain MRIs in the elderly. Their clinical significance is not clear- prior studies have linked them to use of blood thinning medications, cognitive decline and risk of stroke. This randomised controlled trial will determine whether low dose aspirin increases the number of CMH on brain MRI in the healthy elderly after 1 and 3 years, and whether the number and location of CMH affects cognitive function.
Characterising The Effect Of Methamphetamine And Alcohol On Driving Behaviour And Performance

Funding Amount

Summary
Methamphetamine and alcohol are commonly detected among drivers involved in road trauma, but it is currently unclear how these substances contribute to an increased crash risk. This series of studies will (1) look at associations between drug use and attitudes and behaviours towards dangerous driving in people who use these drugs. It will also test the effect of combined alcohol and methamphetamine on (2) more complex thinking patterns and behaviours, and (3) objective driving performance.
Diet Exercise And ARmodafinil For Obstructive Sleep Apnea (OSA) Patients Who Cannot Use Standard Treatments. (DEAR)

Funding Amount

Summary
Obstructive sleep apnea (OSA) affects over 3.5 million Australians and is associated with marked daytime sleepiness and decreased concentration. It is also a common health complication of obesity. Many people are unable to use standard treatments for OSA in the form of a mouth splint or mask worn at night. This study will look at treating the daytime sleepiness with a stimulant medication, Armodafinil, whilst reducing OSA severity gradually with diet and lifestyle modification.

Summary
In 1991, an Australian group found that schizophrenia patients have a reduced brain response to deviant sounds in a repeating pattern of identical sounds. Deviant sounds produce a brain electrical response known as mismatch negativity which is generated by the auditory cortex in the brain's temporal lobes and by adjacent areas in the frontal lobes. A smaller mismatch negativity in patients has since been replicated in laboratories in the US, Europe and Australia.

Deviant sounds produce a brain electrical response known as mismatch negativity which is generated by the auditory cortex in the brain's temporal lobes and by adjacent areas in the frontal lobes. A smaller mismatch negativity in patients has since been replicated in laboratories in the US, Europe and Australia. The importance of this finding is that it had not been previously recognised that patients have low level auditory problems that could potentially have a profound impact on higher level functions. Finnish researchers have gone on to show in healthy individuals that mismatch negativity can reveal important features about how well the auditory system works, e.g., for the brain to respond to a deviant sound, it must have a memory of what happened in the past. Mismatch negativity provides a measure of the integrity of these memory functions. But it also provides an index of how well the auditory system discriminates different aspects of sound, pitch, loudness, and temporal features, such as duration. There are hints in our data and from US researchers that processing of the temporal features of sounds is particularly impaired in schizophrenia. We have also recently discovered that first-degree relatives of patients may have a similar deficit. The aim of this project is to use mismatch negativity to probe what is wrong with the auditory system in schizophrenia and those at risk (first degree relatives). Is it the areas of the brain primarily involved in sound perception (the temporal lobes) that are faulty or is the problem in the frontal lobes? Is it the case that processing of temporal features are particularly compromised and if so, is this a biological marker for schizophrenia. Answers to these questions will greatly enhance our understanding of the nature of the brain dysfunction in schizophrenia.Read moreRead less
Reference Values For Spirometry, Lung Volumes, Diffusing Capacity, And Fractional Exhaled Nitric Oxide In First Nations Australians

Summary
Reference values in lung function tests allow respiratory doctors to accurately interpret results in order to effectively diagnose, treat and manage respiratory disease. Currently, reference values do not exist for First Nations adults. I will recruit 600 healthy First Nations adults from communities in Queensland and the Northern Territory for several lung function tests. Data collected will be submitted to the Global Lung Function Initiative to be incorporated into future guidelines.
