Summary
Many diseases that effect the respiratory system have their primary effect on the lungs and airway themselves but in some conditions, such as obstructive sleep apnea (OSA) and asthma, increased breathing load can induce periods of low blood oxygen which could further contribute to morbidity in these diseases. OSA is a disorder associated with snoring. Patients experience periods of sleep fragmentation and oxygen deprivation due to obstruction of the floppy portion of the upper airway (pharynx) d ....Many diseases that effect the respiratory system have their primary effect on the lungs and airway themselves but in some conditions, such as obstructive sleep apnea (OSA) and asthma, increased breathing load can induce periods of low blood oxygen which could further contribute to morbidity in these diseases. OSA is a disorder associated with snoring. Patients experience periods of sleep fragmentation and oxygen deprivation due to obstruction of the floppy portion of the upper airway (pharynx) during sleep. It affects 4% of men and 2% of women and causes excessive daytime sleepiness leading to increased risk of accidents, high blood pressure and premature cardiovascular disease. Asthma produces airway inflamation and narrowing and affects a wide range of people. Both OSA and asthma are associated with episodes of impaired breathing and reduced levels of oxygen in the blood. Low levels of oxygen in the blood (hypoxia) is well known to impair functioning of the central nervous system. We have recently found that hypoxia blunts sensations of increased breathing load in healthy people and in asthmatics. Hypoxia might therefore contribute to worsening of attacks in these diseases. This study aims to investigate how changes in blood oxygen levels affect brain processing of respiratory signals, how this translates to perception of sensations and the physiological adaptations that people make to cope with increased breathing load. We will also investigate whether the inhibitory effects of hypoxia on central nervous system function extend to other vital protective respiratory reflexes such as cough, awakening from sleep to increased breathing load and upper airway reflexes that are important for maintaining an open airway.Read moreRead less

Residential care for the future will need to meet expanding demands for aged care in a manner which responds to more discerning older people including those from non-English speaking backgrounds and Aboriginal and Torres Strait Islanders with expected increases in the number of services required. To do so design processes must incorporate the needs of those involved in residential care yet meet the requirements of statutory authorities standards for health care provision. This research will provide a comprehensive picture of the issues that impact on the design process and the effect on residential care facilities ability to provide residents and workers with the highest possible quality of life. It will inform accreditation and certification standards.Read moreRead less
Boosting brain plasticity and motor function in older adults. Ageing is associated with a pronounced decline in many motor, cognitive, and other brain functions, but the cause remains elusive. This project will examine the mechanisms that contribute to a decline in brain plasticity and motor function in the elderly. Using novel brain stimulation techniques, the project aims to develop an optimal approach to boost plasticity in the ageing brain and improve motor function.

Ageing is associated with a pronounced decline in many motor, cognitive, and other brain functions, but the cause remains elusive. This project will examine the mechanisms that contribute to a decline in brain plasticity and motor function in the elderly. Using novel brain stimulation techniques, the project aims to develop an optimal approach to boost plasticity in the ageing brain and improve motor function. A better understanding of changes in brain function and plasticity with advancing age is expected to help to optimise the design of preventative programs aimed at rejuvenating motor and cognitive function in the elderly.Read moreRead less
Australian art exhibitions 1968-2009: a generation of cultural transformation. The years 1968 to 2009 witnessed a transformation in the way Australians saw the art of their country. This project investigates the impact of increased funding (government and private) and new scholarship on the curating of art exhibitions, and traces the reconfiguration of Australia’s art history that took place in exhibitions during this period.

A national framework for managing malignant plastics in museum collections. This collaborative project between three universities, four museums and an art gallery aims to discover how to predict and increase the lifespan of malignant plastics or polymers by studying their identification, deterioration and conservation. 5 to 80% of museum collections, composed of growing numbers of plastic or polymer-based materials, need better preservation. Conservators do not have much expertise in preserving plastics, which are contemporary and have a relatively short life expectancy. This project intends to provide museums with a model for prioritising and effectively allocating resources to preserve a vulnerable group of collections for future generations.Read moreRead less

Simulation training has been adopted widely in aerospace, nuclear power and the military, but simulation in medicine has a relatively short history. This research will drive Australia to the forefront of the medical simulation industry. Effective management and treatment of patients is a priority in health care. Medical resources are required to ensure that staff are trained efficiently and effectively on critical medical procedures. The high growth of claims for medical accidents and the accompanying rise in medical insurance adds to the impetus for major hospitals to demonstrate they are using advanced methods for training. The community will benefit from better-trained medical staff, and a better standard of healthcare. Read moreRead less

These are often experienced by young people, frequently as a consequence of intoxication or drinking in unsafe settings. Little work has been undertaken in Australia to systematically examined alcohol-related injuries (ARIs). This study will examine ARIs, identify the frequency with which such problems present to a local hospital, record the nature of the injuries, details of the person sustaining it, and the drinking location. Characteristics of drinking locations and drinking settings, in particular licensed premises, will be examined to determine their association with ARIs. Then an intervention will be undertaken in conjunction with local police, to address the conditions of the drinking environment with the aim of reducing ARIs and other alcohol-related problems stemming from licensed premises. The intervention will form part of a randomised controlled trial where licensed premises, identified through monthly police data as hot spots, receive either an intervention or act as a control. In the following month, controls receive the intervention (a cross-over design). The intervention was established in 1998 by Gold Coast police and involves police, fire and liquor licensing officers undertaking an on-site inspection and taking prescribed actions. It is hypothesised that this action should result in a decreased level of ARIs being generated from premises which receive the intervention, compared to those that do not. This is an intersectoral, collaborative project aimed at improving community safety through a concerted effort by police, health and the licensees.Read moreRead less
