There are about 10460 clinical studies being (or have been) conducted in Australia. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
The purpose of this trial is to study the effects of a medication already widely used to treat cardiovascular disease and diabetes, in reducing the progression of myeloma.
The purpose of this study is to examine gene expression profiles by DNA microarray in patients who are responders and non-responders to interferon and ribavirin treatment for hepatitis C virus (HCV). Genes involved in inflammation and fibrosis and mediators of the Th-1 lymphocyte response will be looked for. It is hoped that genetic targets for future more effective and less toxic treatments will be identified.
The purpose of this study is to examine the effect of GB virus C (GBV-C) on the natural history of chronic hepatitis C virus (HCV) infection in subjects co-infected with HIV and HCV. The other aspect of the study is to assess the effect of GBV-C on the severity of liver disease due to chronic hepatitis C in subjects co-infected with HIV and HCV. This will be done by determining the point prevalence of co-infection retrospectively then following that cohort prospectively. In addition, further individuals will be recruited in a prospective manner.
We aim to investigate the effectiveness and safety of nitrous oxide (N2O) in anaesthesia. Hypothesis In patients undergoing anaesthesia for major surgery, avoidance of N2O will reduce hospital length of stay when compared with otherwise identically managed surgical patients receiving N2O as a component of their anaesthesia.
Test the hypothesis that the implementation of real-time, computer-prompted algorithms in the first half hour of trauma management will result in a measurable reduction in management errors associated with the reception and resuscitation of major trauma patients. Demonstrate that a reduction in management errors will translate into a reduction in morbidity and mortality.
Gastro-oesophageal reflux (GOR) has been found to be prevalent in children with cystic fibrosis (CF)and may further worsen lung damage via reflex bronchospasm or pulmonary aspiration. Chest physiotherapy may result in increased episodes of GOR as demonstrated in children. Lung transplantation may worsen pre-existing GOR. This study will determine the prevalence, severity and significance of symptomatic and silent GOR in adults with CF before and after lung transplant using 24hr oesophageal pH monitoring, a valid symptom questionnaire, quality of life questionnaires and gastric emptying studies. This study will identify the extent of GOR in a large adult CF population and the impact on lung function and quality of life together with the effects of medical and physiotherapy treatment on gastro-oesophageal function.
This study looks at the iontophoresis of urotensin II in chronic liver disease patients.
This study is looking at the detection of vasoactive peptides in portal hypertension.
This clinical trial will determine if postoperative patients who have postoperative pain, which has been refractory to morphine administration, will have improved pain relief following a bolus administration of ketamine as compared with an ongoing morphine dosing regimen
The inferior vena cava (IVC) is a large vein that enters the bottom part of the heart. Venous blood from the lower portion of the body drains into the IVC. The IVC then returns blood back to the heart. An IVC filter is placed to help prevent the blood clots moving from the legs to the heart or lung. The idea behind using a filter in the IVC is to capture potential fatal pulmonary emboli at an anatomical location where they may pose less risk for the patient. Early filters, 1960's and 70's were, remained in the vein permanently. More recently, temporary or retrievable filters have been developed and are being widely used. Complications have been demonstrated with long-term placement of IVC filters. In a randomised study it was found that that patients with IVC filter placement had greater than three times the incidence of recurrent deep vein thrombosis (DVT) compared to their control population at two years. Blockage of the vein, recurrent pulmonary emboli, filter penetration and filter fragmentation have all been described. With the advent of retrievable filters (filters that can be place temporarily and then removed at a later date) there has been renewed popularity for placement of temporary filters. To our knowledge, no one has yet to follow the population of intended temporary IVC filters, who undergo failed retrieval, and consequently end up with a permanent IVC filter. We plan to prospectively enrol 40 Alfred patients who have undergone a temporary IVC filter placement and subsequently have had failed IVC filter retrieval. Our aim is to evaluate the long term outcomes for patients with failed IVC retrieval. Specifically we will determine the risk, due to failed filter retrieval, of: - IVC stenosis - IVC occlusion - Development of DVT and - analyse the clinical outcomes (symptoms), their prevalence and their distribution Patients will receive routine care and their data will be analysed annually as collected. The follow-up period is indefinite and will be at the discretion of the treating doctor.
