Summary
Diseases like influenza, commonly called ‘the flu’, produce symptoms such as fever, headaches, lethargy and lack of appetite. What most people don’t realise is that it is not the influenza virus that produces these symptoms, but the body’s immune response to the influenza virus. This immune response comes about because the influenza virus stimulates cells to produce molecules called cytokines, and cytokines have many effects in the body, including causing fever and a lack of appetite. In severe ....Diseases like influenza, commonly called ‘the flu’, produce symptoms such as fever, headaches, lethargy and lack of appetite. What most people don’t realise is that it is not the influenza virus that produces these symptoms, but the body’s immune response to the influenza virus. This immune response comes about because the influenza virus stimulates cells to produce molecules called cytokines, and cytokines have many effects in the body, including causing fever and a lack of appetite. In severe infections like those caused by the influenza virus responsible for the pandemic of 1918, and during “bird ‘flu” (H5N1) infections, people die because the immune response becomes overwhelming. Cytokines produced during these sorts of responses are actually very harmful, even though in small amounts they help to kill the virus and cure the infection. Researchers working in this field have likened these severe responses to a “cytokine storm”. This project focusses on finding alternative therapies such as those used in Chinese medicine to prevent a cytokine storm happening, so that if an influenza pandemic occurs these treatments could be quickly made available to everyone. Examples are the Chinese herbs Angelica sinensis and Salvia miltiorrhiza. Recent laboratory studies in New York have shown that both of these herbs have potent cytokine effects, decreasing levels of an inflammatory cytokine known to be associated with death in both malaria and sepsis. Our study aims to closely examine the effects of these Chinese herbs, as well as other commercially available herbal extracts, and traditional combinations of herbs, to find synergies between them that could be used to treat severe influenza infections.Read moreRead less

IBS is the most common chronic medical disorder of the digestive tract with 10% prevalence in the Australian population. Characterised by abdominal pain and altered bowel habits, it significantly affects quality of life and has major socioeconomic implications. IBS is increasingly recognized as a complex multi-factorial condition with psychogenic, hormonal and immune components. It is poorly addressed by current pharmaceutical treatments. Medical treatment of IBS remains unsatisfactory, with incomplete benefits offered by a single drug approach. The multi-factorial nature of IBS renders it an ideal candidate for evaluation with a more complex mix of low dose agents offered by herbal medicine. Specifically, CHMs by their complex chemical nature have substantial potential in the treatment of IBS because of their range of physiological effects on both bowel function and the central nervous systems We will perform a clinical trial of 8 weeks to determine the effectiveness of a chemically standardised CHM preparation in 160 patients with constipation predominant IBS patients compared to an identical placebo (sham). This project builds on our previous studies that demonstrated an effectiveness of CHM for IBS superior to current interventions. We’ve validated methods to ensure chemical standardisation of herbal medicines; validated approaches to psychosocial assessment of cognitive and behavioural changes in IBS patients; and have validated physiological, mechanistic evaluation of the lower bowel in response to treatment. The significance of the current proposal lies in its ability to provide a standardised, multi-component CHM (8 herbs) for the comprehensive clinical evaluation of the efficacy and safety of this type of therapy for IBS, and to provide insight into the relevant mechanisms of action. This project draws together the unique skills and previous studies from the Centre for Complementary Medicine Research (UWS), and the Gastrointestinal Investigation Unit of RNSH, USYD. This innovative project is medically important because it addresses a common gastrointestinal disorder with high socioeconomic implications for which conventional western medicine has failed to produce a cure or adequate palliative treatment.Read moreRead less
Alternatives To Homologous Blood Transfusion - Development Of Evidence- Based Decision Aids.

Summary
Transfusion of donor blood is the traditional means of treating blood loss resulting from injury or during surgery. Donor blood is in short supply and in the past there have been episodes of contamination by viruses that have led to hepatitis and AIDS. Consequently there is much interest in a range of techniques designed to reduce the need for transfusion of donor blood. One of the most popular is transfusion of patients' own blood (autologous transfusion).

Donor blood is in short supply and in the past there have been episodes of contamination by viruses that have led to hepatitis and AIDS. Consequently there is much interest in a range of techniques designed to reduce the need for transfusion of donor blood. One of the most popular is transfusion of patients' own blood (autologous transfusion). Despite the popularity of some of these techniques their true value is not really proven. They may be capable of diminishing the need for a transfusion of donor blood, but the long-term effects of this are not clear. In addition the preparation of autologous blood is a burden for overworked blood banks, and autologous blood may itself be associated with its own problems. The main aims of this study are to carry out reviews of the best quality trials of the various alternatives to transfusion of donor blood and to carry out surveys to find out what patients and doctors think. In a third phase of the project we will use the information gathered in the first two phases to design decision aids. These are comprehensive structured summaries of the available evidence to enable patients and their physicians to collaborate in making informed decisions that are likely to lead to the best outcomes for patients. The products of the research will be a number of reviews of 'best evidence' that appear in the International Cochrane Library, available to health professionals around the world. In addition, the decision aids, if successful, will be made available in a form that can be used by all Australian patients who are facing surgery that is likely to require a blood transfusion.Read moreRead less

It could also lead to new drugs that can kill tumour cells more effectively by directly triggering the normal death switch of the cell.Read moreRead less
Combinatorial Therapeutics In High-risk Infant Acute Lymphoblastic Leukaemia

Summary
Modern therapies for children with leukaemia are curative in more than 90%. In contrast, survival for infants less than one year of age at the time of diagnosis is less than 50%. Better therapies are desperately needed. From laboratory testing we have discovered effective novel cancer drugs, which are not currently used for treatment of babies with leukaemia. We will evaluate novel drug combinations and test them in model systems, such that they can be fast-tracked to the clinic.
