Summary
Peritoneal dialysis (PD) is a form of home dialysis that is both substantially cheaper and associated with better early survival than standard hospital-based haemodialysis. Its use in Australia has been severely limited by poor outcomes compared to the rest of the world. This international study aims to identify “real world” PD centre practices that will lead to better outcomes for Australian patients, greater uptake of home dialysis and health savings of tens of millions of dollars annually.

Summary
Lung cancer is the third leading cause of death in Australia. People with lung cancer experience a complex mix of symptoms that can provoke significant distress and impair physical function. This study aims to develop and test a home based exercise and self-management support program to increase function and physical activity levels, reduce levels of depression and improve quality of life of people with lung cancer.
Deciphering Mechanisms Of Liver Allograft Tolerance

Summary
The liver has paradoxical properties: it is the site of effective immune responses to pathogens, but under some circumstances, it is known to induce harmless immune responses. Liver transplants are more readily accepted than other organ grafts in the absence of immunosuppressive drugs but little is known about the mechanisms that prevent an effective response. This proposal aims to unravel these mechanisms. This project will have important implications for transplantation studies.

Preterm birth is a major problem in our society, and has enormous consequences for parents and children. It also has a major impact on scarce financial resources. When women present in preterm labor, current therapies have only limited success in stopping contractions and postponing birth.

It also has a major impact on scarce financial resources. When women present in preterm labor, current therapies have only limited success in stopping contractions and postponing birth. They have not been shown to reduce the rates of the serious neonatal problems associated with prematurity. This project will be coordinated in Newcastle, N.S.W., and will involve major perinatal centres throughout Australia, along with overseas centres. It will test a new combination of drugs for their ability to postpone delivery in women presenting with preterm labour. It is postulated that the combination of drugs will be more effective than existing therapies. The drugs used in the trial are Nifedipine and Rofecoxib. Complications of prematurity include neonatal death, cerebral palsy, visual and hearing impairment, and chronic lung disease. These complications are most significant in extremely premature infants - in particular, those under 28 weeks gestation at the time of their delivery. For this reason, the study will focus only on women presenting in labour below 28 weeks. The ability to stop labour is important, but the main aim of any treatment for preterm labour is to reduce the rates of neonatal death and handicap. Babies born to women enrolled in this study will be followed for a period of one year after birth to assess their outcomes. It is our hypothesis that the combination of Rofecoxib and Nifedipine will result in lower rates of death and handicap in babies than Nifedipine alone. In addition, we will examine the rates of side effects in women receiving therapy. Currently used therapies, including intravenous ventolin, have high rates of maternal side effects. Nifedipine and Rofecoxib have both been shown to have low rates of maternal side effects.Read moreRead less

Summary
Each year approximately 8000 men in Australia and New Zealand develop prostate cancer which has not spread widely and which is amenable to attempted cure by surgery or radiation. Prostate cancer depends for its growth on the male hormone, testosterone, which circulates in the blood. As a result treatment which reduces testosterone level ('androgen deprivation' [AD] therapy) can produce shrinkage of prostate cancer.

Prostate cancer depends for its growth on the male hormone, testosterone, which circulates in the blood. As a result treatment which reduces testosterone level ('androgen deprivation' [AD] therapy) can produce shrinkage of prostate cancer. In fact AD has caused temporary but valued relief to millions of men with cancer of the prostate that has spread throughout the body for the last five decades, worldwide. It remains uncertain however whether AD administered before surgery or radiation will benefit any of the 8000 men each year who develop localised cancer by shrinking the cancer first. In 1996 a trial involving 800 men across Australia and New Zealand commenced under the auspices of the Trans-Tasman Radiation Oncology Group (TROG) to answer the questions: 1 - Does either 3 or 6 months AD prior to radiotherapy reduce the chances of recurrence of the cancer after radiotherapy? 2 - Does such therapy reduce the volume of tissue requiring radiotherapy and hence the chances of long term side effects after radiotherapy? This grant will support collection of follow-up information from the trial and hence answers to the questions asked.Read moreRead less
An International Clinical Trial To Evaluate New Therapies To Improve Survival Of Children With Relapsed Acute Lymphoblastic Leukaemia

Summary
Children who relapse with childhood leukaemia have only a 50% chance of being alive after 5 years. We will participate in a new international trial involving most European and all Australian and New Zealand childhood oncology centres, to test the effectiveness of promising new treatments and to perform biological studies which should enable doctors in future to pick the best treatment for each of these patients.

Human cytomegalovirus (HCMV) is a herpesvirus which infects a majority of the population. HCMV is a significant cause of serious, life-threatening disease in neonates and in people who are immunosuppressed. Transplant recipients such as bone marrow, kidney and heart transplant patients are particularly at risk of developing HCMV disease.

HCMV is a significant cause of serious, life-threatening disease in neonates and in people who are immunosuppressed. Transplant recipients such as bone marrow, kidney and heart transplant patients are particularly at risk of developing HCMV disease. Like other herpesviruses, after initial infection HCMV can establish a life-long latent infection. During latency, the virus remains dormant in the human body and no infectious virus is made. However, when conditions are right the virus can awaken (ie reactivate) from its latent state, producing new infectious virus and disease. It is in immunosuppressed individuals such as transplant patients that viral latency and reactivation are of most medical concern, yet viral latency remains very poorly understood. This project has three major components. Firstly, we aim to continue studies which are defining what viral genes are active (ie expressed) during latent infection. Identification of these genes and determination of how they function may have profound implications to our understanding of latency. Secondly, we will examine how human cells are affected when they become latently infected. A new and exciting technology called DNA microarray now makes it possible to examine the expression of many thousands of genes in a single experiment. For the first time, we will be able to determine how the cell changes during latency and reactivation. The study of viral and cellular gene expression during latency may contribute to the development of drugs which interfere with the viruses ability to become latent or reactivate. Thirdly, we have preliminary results which suggest that latent HCMV may actively avoid detection by the immune system. In this project we also aim to determine the mechanism by which the virus interferes with the expression of molecules which are an essential component of our immune system.Read moreRead less

It is in immunosuppressed individuals such as transplant patients that viral latency and reactivation are of most medical concern, yet viral latency remains very poorly understood. The overall aim of these studies is to provide a much better understanding of how CMV latency is established and maintained, with the ultimate goal of making advances for the design of anti-viral therapies to disrupt these processes. This project has three major components: Firstly, we aim to identify and characterise viral gene expression during the establishment of latency and these findings will have profound implications to our understanding of latency. Secondly, we will examine how human cells are affected when they become latently infected. A new and exciting technology called DNA microarray now makes it possible to examine the expression of many thousands of genes in a single experiment. For the first time, we will be able to determine how the cell changes during the establishment and maintenance phases of latency. Thirdly, we will apply microarray technologies to determine how human cell genes are altered in response to the expression of individual viral genes that are active during the latent phase of infection.Read moreRead less
