Summary
Anaesthesia and major surgery in patients with coexisting important medical problems present a major challenge to health professionals to avoid and minimise life threatening complications of such surgery. Accurate prediction of which patients are likely to fare badly, and therefore need more intensive peri-operative care and supervision, and knowing definitively whether epidural techniques really do improve the outcome of surgery are issues of central importance in the practice of anaesthesia.

Accurate prediction of which patients are likely to fare badly, and therefore need more intensive peri-operative care and supervision, and knowing definitively whether epidural techniques really do improve the outcome of surgery are issues of central importance in the practice of anaesthesia. Providing clear answers to both questions requires careful analysis of large amounts of data in which systematic and random errors have been minimised. Databases from well-designed and supervised clinical trials represent an invaluable resource in this regard because they have been compiled through the rigorous application of unambiguous definitions and protocols during the process of recording, coding and entering the information. By bringing together the resources and expertise of the MASTER Trial group and the Collaborative Overview of Randomised of Trials of Regional Anaesthesia (CORTRA), both of which are major international projects led from the Australasian region, we have a unique opportunity to provide exceptionally robust answers to some of the most challenging issues in anaesthesia. The combined study of two large international databases will provide a more precise quantitative analysis of the components of preoperative risk and their relationship to life threatening post operative complications, and the possible role of epidural and spinal anaesthesia in minimising risk by reducing the frequency of these complications.Read moreRead less

Summary
This application aims to confirm our preliminary identification of the first candidate gene as a risk factor for developing venous leg ulceration. Since patients with venous leg ulcers experience pain and psychological consequences including anger and depression, all of which impact negatively on quality of life, active prevention of ulceration will have significant lifestyle and financial benefits.

Since patients with venous leg ulcers experience pain and psychological consequences including anger and depression, all of which impact negatively on quality of life, active prevention of ulceration will have significant lifestyle and financial benefits. Venous leg ulcers occur in patients who have venous disease, in particular in patients with previous deep vein thrombosis. However, not all patients with a deep vein thrombosis or other forms of venous disease will go on to develop a venous ulcer. Our preliminary results show that patients with a venous ulcer have a greater frequency of this gene than healthy controls without venous ulcers, and suggest that patients with the candidate gene have a greater risk of developing venous ulceration. In this study we aim to determine whether the gene itself contributes to ulcer susceptibility or whether it is just a marker of that susceptibility. We can do this by assessing related genes and the levels of the protein produced by this gene. In this study we also aim to assess whether patients with a proven deep vein thrombosis are more likely to develop venous ulceration if they have the candidate gene. These studies have the potential to lead to the development of a diagnostic screening test for use in patients with venous disease, to assess the likelihood of developing leg ulceration. This will enable more active treatment to prevent leg ulceration. If this gene contributes to ulcer susceptibility new specific treatments may be developed for ulcer management and prevention.Read moreRead less
