Summary
Vasculitis is a life-threatening disease, and the current treatment for this condition is not satisfactory. This clinical trial aims to determine 1) if plasma exchange can lower mortality and the development of severe kidney failure due to this disease, and 2) if the use of lower doses of corticosteroids can lessen the infectious complications of treatment. This trial is part of a major international effort which will involve a total of 500 patients from Australia, UK, Europe, USA and NZ.
A Randomised Controlled Trial Examining Stability Of New Types Of Highly Porous Surfaced Acetabular Components In Total Hip Replacement

Summary
Numbers of total hip replacements are steadily increasing. The most common complication of hip replacement is late implant loosening, which can be predicted by early migration. We will examine early migration of a trabecular metal acetabular cup without screws, compared to a titanium fibre metal acetabular cup fixed with screws. Ideally, an acetabular cup would achieve a level of initial stability by press-fit alone without screws, as screws increase the risk of bone loss around the prosthesis.

Summary
Shortness of breath at the end-of-life is one of the most feared symptoms. Unlike most other symptoms, it worsens as death approaches. Despite the fact that more than 50,000 Australian will die an expected death in the next year, of whom the majority will have breathlessness toward the end-of-life, we know little about how best to treat this symptom.

Unlike most other symptoms, it worsens as death approaches. Despite the fact that more than 50,000 Australian will die an expected death in the next year, of whom the majority will have breathlessness toward the end-of-life, we know little about how best to treat this symptom. Oxygen is frequently introduced but we have not identified whether it is more effective than medical air, and, if it is more effective, which patients would most benefit from it. Because of this lack of evidence, oxygen is only funded in Australia in community settings for people who have severely low oxygen levels in their blood. Palliative oxygen is provided on a compassionate basis at times but this is on an ad hoc basis and does not ensure equitable access for people at the end of life who experience shortness of breath. This multi-centre study will compare oxygen and air, with neither the participant nor caring clinicians knowing which treatment they will receive. After careful explanation, volunteers who agree to participate will be asked to use the oxygen machine for at least 15 hours each day for 7 days and fill out a diary twice each day. Five centres across Australia are planning to enroll 240 participants in this study. Outcomes will include whether the sensation of breathlessness has improved, the overall quality of life while being treated, the ability to perform activities of daily living and any side effects experienced. This study is eagerly awaited by clinicians and health planners not only in Australia but in North America and Europe. This study will provide data in a long-standing international debate about the role of oxygen in people with relatively normal levels of oxygen in their blood who suffer from shortness of breath at the end-of-life.Read moreRead less
A Randomised Trial To Control Sexually Transmitted Infections In Remote Aboriginal Communities.

Summary
This project will trial strategies for attaining clinical best practice in sexual health with an overall objective of reducing the high rates of sexually transmitted infection in remote Aboriginal communities in central and northern Australia. The trial will take place in 21 communities of which seven will be randomly assigned in each of the three years of the trial. This trial will determine whether strengthening primary health services can reduce the level of these infections.
Radiostereometric Analysis Of The Effect Of A Large Articulation On Prosthetic Wear And Migration After Hip Replacement

Summary
At total hip replacement, there has been a recent trend to use prostheses with a larger ball and liner in the socket. This may decrease the risk of post-operative dislocation, but may also increase the amount of wear, leading to bone loss and loosening of prostheses, which may then require replacement. This project will use a special type of x-ray to determine whether wear and movement of these new prostheses is clinically acceptable, so that they can be used with confidence in patients.
Systematic Expansion Of The Clinical Evidence Base In Opioid Prescribing For Refractory Dyspnoea At The End Of Life

Summary
Morphine can relieve breathlessness in the palliative setting. But many important questions remain. What is the best dose, should the dose change over time, do different medications provide the same relief, and how common is dyspnoea in the general population? This three part project will extend our knowledge to answer these questions. Population data will provide critical background to plan best care for future palliative patients distressed by breathlessness.
The Role Of Arousal And Respiratory Control Factors In The Pathogenesis Of Obstructive Sleep Apnoea

Summary
Sleep apnoea (OSA) is a very common breathing disorder in sleep characterized by repetitive closure of the collapsible portion of the throat with serious effects on sleep quality and health. Basic causes of OSA are still largely unknown. We will investigate waking responses to breathing load and related respiratory control factors that we believe may be fundamental causes of OSA, and potentially explain many features of OSA including worsening in light sleep and with increasing age.

Patients with APD are a large population at high risk of health resource use, unnecessary medication use and emergency admission to hospital or residential care facilities. Although previous research has identified difficulties experienced by caregivers of the elderly in general, very little research has been undertaken with carers of patients with APD. The study will compare the usual practice of educating patients with APD who commence home oxygen therapy (HOT), and their carers, against a more detailed and individually targeted education program that increases the skills of patients and carers. This study has the potential to reduce hospital-residential care readmission, reduce carer distress, improve patient outcomes, reduce adverse effects of oxygen therapy and medication use, and minimize inappropriate presentation to tertiary care emergency departments.Read moreRead less

Obstructive sleep apnea (OSA) affects 4% of men and causes excessive daytime sleepiness leading to increased accidents, high blood pressure and premature cardiovascular disease e.g. heart attacks and strokes. OSA is characterized by repetitive obstructions of the floppy portion of the throat during sleep with adverse effects on oxygen levels and sleep quality.

OSA is characterized by repetitive obstructions of the floppy portion of the throat during sleep with adverse effects on oxygen levels and sleep quality. OSA is strongly associated with obesity and is 2-3 times more common in men than women. How obesity and male gender predispose to OSA is not known. We will investigate two factors that we believe are most likely involved in causing and explaining this gender difference in OSA. We will examine if breathing responses with brief awakening are sufficient to promote OSA patterns of breathing in snorers and if they are greater in male than female OSA patients. We have already shown that healthy men have greater breathing response to arousal compared to women. These brief arousals occur hundreds of times a night in OSA patients, and over-breathing on arousal may increase the probability of upper airway obstruction on falling back to sleep. We will also investigate why even healthy men show greater breathing responses compared to women. Men tend to accumulate fat centrally, particularly in the abdomen, whereas in women fat tends to be distributed more to the hips and thighs. This could be very important in OSA because downward pull exerted on the upper airway by the diaphragm is likely to be reduced in people with more abdominal obesity. This mechanisms has not yet been studied in humans. We will therefore investigate if increased forces placed on the diaphragm during sleep make the upper airway more prone to collapse. We will also investigate these effects during sleep onset, when there may well be important changes in diaphragm position as muscles relax.Read moreRead less
