Summary
People with cystic fibrosis (CF) produce thick mucus that is not cleared normally from the lungs. This retained mucus often becomes infected, which progressively damages the lungs. Various physical therapies which may help clear secretions are being used in CF. These include several types of devices which provide positive pressure to the airways. However, it is not known to what extent these devices, or other interventions such as manual chest physiotherapy and exercise, enhance mucus clearance. ....People with cystic fibrosis (CF) produce thick mucus that is not cleared normally from the lungs. This retained mucus often becomes infected, which progressively damages the lungs. Various physical therapies which may help clear secretions are being used in CF. These include several types of devices which provide positive pressure to the airways. However, it is not known to what extent these devices, or other interventions such as manual chest physiotherapy and exercise, enhance mucus clearance. As a result, it is not currently possible to scientifically prescribe intervention(s) to enhance mucus clearance in CF. This is partly because much of the research that has been performed in this area has been poorly-designed or has used inaccurate measures. Also, recent research has shown that these therapies may have significant effects beside their effect on mucus clearance. For instance, bacterial infection and the exchange of oxygen and carbon dioxide between the blood supply and air in the lung may all be affected by these interventions. Notably, the extent of benefit or detriment seen in these parameters does not always correlate with the effect on mucus clearance. We therefore believe a series of experiments is necessary to provide evidence upon which the scientific selection of mucus clearance therapies may be based. We have developed a new technique which allows clearance of mucus from the airways to be objectively measured in three-dimensions (3D). We intend to use the 3D technique to examine the effects of three different positive pressure devices, exercise, and manual chest physiotherapy on mucus clearance. Based on the outcomes of this research, we intend to compare the most appropriate therapy to performing no mucus clearance therapy in a short term trial. This trial will assess changes in the following: bacterial infection, mucus plugging in the airways, how well the lungs move air and exchange oxygen and carbon dioxide, and the patient's quality of life.Read moreRead less
The Diagnosis Of Obstructive Sleep Apnea In Primary Care

Summary
The gold standard method for diagnosis of sleep apnea is the overnight sleep study. These tests are expensive, have long waiting lists and are hard to access outside larger cities. We aim to determine if general practitioners can combine information from questionnaires and a simple home diagnostic test, to confirm or rule out sleep apnea. The results of this study will eventually lead to more accessible and efficient diagnosis and treatment of this common condition.

Summary
Patients with chronic respiratory disease have limited exercise capacity, which severely impairs their quality of life. The mechanisms responsible for this impairment may relate to their lung disease, or to the long-term effects that inactivity has on the cardiovascular and musculoskeletal systems. Pulmonary rehabilitation programs involving whole-body exercise are now widely used as an addition to standard medical therapy as a way of decreasing symptoms and optimising function.

The mechanisms responsible for this impairment may relate to their lung disease, or to the long-term effects that inactivity has on the cardiovascular and musculoskeletal systems. Pulmonary rehabilitation programs involving whole-body exercise are now widely used as an addition to standard medical therapy as a way of decreasing symptoms and optimising function. While these generalised, broad-based programs result in modest improvements in peripheral muscle function, cardiovascular function, functional exercise capacity and quality of life, it is now apparent they have little or no effect on respiratory muscle function, which is also greatly impaired in COPD. The aims of this study are to answer two longstanding questions that are fundamental to rehabilitation programs in patients with COPD (i) does a program of specific respiratory muscle training alone improve whole-body exercise capacity, dyspnoea, and-or quality of life? and (ii) does the addition of a program of specific respiratory muscle training to a standard whole-body exercise rehabilitation program result in improvemed exercise capacity, dyspnoea and-or quality of life to a greater degree than a program of whole-body exercise training alone? The study is of importance to patients with COPD by investigating the mechanisms underlying the improvement in exercise capacity following a rehabilitation program and the role of respiratory muscle training in such a program. By more accurately defining the mechanisms of exercise limitation we may be able to maximise the benefits obtained during a rehabilitation program, including improved work capacity, reduction in the degree of breathlessness and improved quality of life.Read moreRead less

Summary
COPD is Australia's most burdensome respiratory disease with over 200,000 new cases diagnosed each year. Shortness of breath is a cardinal feature of this disease.This project will examine the mechanisms of this symptom in patients with chronic lung disease. Four studies will be completed in total, each exploring different factors that may contribute to shortness of breath observed in patients. This research is likely to lead to improved management of this distressing condition into the future.
