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

Summary
Multi-drug resistance in bacteria is increasing at an alarming rate. We have diminishing therapeutic options, and there are few antibiotics in the drug development pipeline that offer much hope. It is therefore important that we look towards ways of further optimising the use of antibiotics that we currently have available. An important last line of defense drug, linezolid, has been available in Australia for less than 2 years and already resistance is occuring.

We have diminishing therapeutic options, and there are few antibiotics in the drug development pipeline that offer much hope. It is therefore important that we look towards ways of further optimising the use of antibiotics that we currently have available. An important last line of defense drug, linezolid, has been available in Australia for less than 2 years and already resistance is occuring. In addition, with broader use of this drug outside clinical trials, there has been an increasing concern over its toxicity to important blood cells. We seek to better understand the determinants of linezolid resistance and toxicity, so that novel dosing strategies may be developed to optimise its use (reduce toxicity and enhance efficacy) thereby extending the usefulness of this last line of defense antibiotic.Read moreRead less
