Summary
Giant cell arteritis (GCA) is the most common form of vasculitis in people over 50 years of age. If untreated it can cause catastrophic complications including blindness, though this can be prevented if treated early. Although there is clear evidence for a role of genetic factors in GCA, these have been little studied. We have established an Australian-led International consortium, with clinical, basic science and statistical expertise to thoroughly investigate this devastating disease.
STudy Of Risk Assessment To Reduce Complications In Patients Following Noncardiac SurgerY (STRATIFY)

Summary
Cardiac problems account for many complications in patients undergoing major non-cardiac surgery, and even apparently minor cardiac damage is a marker of high risk for subsequent adverse events. Unfortunately, while money and effort is expended on identifying patients at risk, the appropriate response to this risk is quite unclear. The performance of bypass surgery or balloon angioplasty in order to treat the underlying coronary disease of at-risk patients is used in other situations, and reduce ....Cardiac problems account for many complications in patients undergoing major non-cardiac surgery, and even apparently minor cardiac damage is a marker of high risk for subsequent adverse events. Unfortunately, while money and effort is expended on identifying patients at risk, the appropriate response to this risk is quite unclear. The performance of bypass surgery or balloon angioplasty in order to treat the underlying coronary disease of at-risk patients is used in other situations, and reduces longterm risk. However, in many patients undergoing major noncardiac surgery, this approach may be inappropriately aggressive, as these patients are often elderly, have other diseases that make heart operations more difficult and risky than usual, and in any case may have a reduced life expectancy from the disease necessitating the operation. As the most critical issue is to ensure that patients undergo their surgery uneventfully, an alternative is the use of intensive medical therapy to protect the heart. This multicentre study, based at Brisbane hospitals that perform large numbers of major operations, will follow up patients for complications, and outcome (including quality of life) will be assessed six months after the operation. We will address two important questions about the efficacy and cost of risk reduction strategies. First, in patients at higher levels of risk and with a positive stress test, could a combination of medical therapy designed to protect the heart be as effective as current approaches, which include the performance of bypass surgery or coronary balloon angioplasty? Second, in patients identified as being at some risk - but low risk - are drugs sufficiently effective to avoid the need for further testing to quantify risk? As the population continues to age, the numbers of at risk patients undergoing major surgery will increase, and answers to these questions will provide important information to guide their management.Read moreRead less
Understanding Changes In The Mammalian Prenylome Induced By Statins And Prenyltransferase Inhibitors

Summary
Prenylation, the covalent attachment of isoprenoid lipids to proteins, is widespread in mammalian cells. Essential for a protein's normal function, it contributes to the progression of cancer and inflammation. We have developed a novel technology to identify all prenylated proteins in the cell. Aided by this method, we will analyse the effect of statins and anti-cancer drugs on protein prenylation. This will provide guidance in identifying a more effective clinical use for them.
