A prospective, single-blind, multicentre, randomised clinical trial to evaluate the clinical impact and resource implications of the high-sensitvity troponin assay in the care of patients presenting with suspected ACS. The study will enroll 2000 patients presenting to an emergency department with clinical features in whom the treating physician seeks to measure serum troponin level. The study will be run across 5 metropolitan public hospitals in Adelaide, South Australia. Patients will be randomised to either the 4th generation or 5th generation troponin reporting system. Information will be collected on presenting chest pain characteristics. Clinical outcomes (death, new/re-MI, bleeding, stroke, revascularisation) including quality of life will be sought in-hospital and at 30 days, 6-months and 12-months and cost effectiveness will be measured at 12-months.

There is a well established association between rheumatoid arthritis (RA) and bronchiectasis. It has been observed that patients who suffer RA are between 10 and 30 times more likely to develop bronchiectasis. The aetiology of this association is unknown. Mannose-binding lectin (MBL) is a component of the immune system which is active in fighting infection. It is thought that a deficiency in MBL may predispose individuals to infection especially if there is coexisting immunodeficiency. This study seeks to find an association between MBL deficiency and the development of bronchiectasis in patients with RA as a means to providing insight into the association between the two diseases.

The aim of this study is to measure the release of PLA2 enzymes during elective coronary stenting in patients with coronary artery disease and to compare this release with known characteristics of the patient and their current treatment.

Not being able to breath enough overnight is a major problem for an increasing number of Australians with obesity. Obesity hypoventilation syndrome, as this problem is known, is now the major reason for complex, overnight breathing support in Australia. This potentially fatal disease can be managed using two different strategies; a cheaper, simpler option available to more people or a more expensive approach that requires specialised services. The more complex approach may not be better if fewer people are able to take advantage of it. In this twelve month study, people with obesity hypoventilation syndrome will be randomised (like flipping a coin) to receive either the simple or the complex way of managing the disease. The primary question we are looking to answer is whether the more complex approach is really better than the simpler one. Specifically, the study will determine which treatment is better for patients in terms of quality of life, blood test results and and how easily they can get out and about. The study will also help establish which of these approaches is more cost-effective for the community.

Retention of weight gained during pregnancy contributes to overweight and obesity and subsequent chronic disease risk, with the associated personal, financial and public health burdens. Women who are overweight or obese at beginning of pregnancy are more likely to gain excess weight and retain this weight after pregnancy. Women who do not lose weight by 6 months postpartum are more likely to be overweight or obese over the long term. Approximately one third of women who deliver at the MMH are overweight or obese at the beginning of pregnancy. A 2008 MMH Nutrition and Dietetic audit demonstrated that, of the 102 women surveyed, 50% of the women who were overweight, 75% of women who were obese and 100% of women who were morbidly obese gained in excess of their recommended weight gain range for pregnancy. Our MMH patients are at very high risk of retaining weight after pregnancy and developing associated chronic diseases, thus implementation of weight management interventions is urgently required. Limited data exist regarding the most effective methods of supporting weight loss after pregnancy. However, diet and exercise, with behavioural change and support are known to be important elements to be included in any program. Usual models of weight loss care (e.g. multiple group/clinic attendances) are not as appropriate in this population group due to childrearing demands. Our research aim is to develop, implement and evaluate an innovative postpartum weight management program that includes evidence-based behaviour change strategies to support postpartum weight management that is delivered in a format suitable for MMH postnatal (PN) patients.

The aim of this study is to assess the effect of elective coronary stenting procedures on the release of enzymes (PLA2) found in the wall of the coronary artery, and how this release relates to the characteristics of the artery wall as assessed by novel invasive imaging tools

The literature suggests that a carbohydrate rich beverage before surgery positively affects postoperative recovery and improves subjective patient wellbeing. The positive effect of carbohydrate rich oral fluid intake on perioperative urine output and fluid and electrolyte balance has also been shown. Although the metabolic and electrolyte advantages of using a carbohydrate rich preoperative beverage have been demonstrated, there is less information about whether these advantages translate into improved postoperative clinical outcomes, such as whether preloading with a carbohydrate drink reduces hospital length of stay. The current study has been designed to establish the efficacy of preoperative carbohydrate drink in shortening time to discharge in a prospective randomised clinical trial for gastroenterology patients undergoing elective bowel surgery.

Women with a healthy lifestyle during their pregnancy have healthier pregnancies and healthier babies. Their long term health is also improved, resulting in a better quality of life for them and their family, as well as lower health system costs with fewer doctor and hospital visits required. Currently, we do not know the best way to support women to make lifestyle changes to ensure they have the healthiest start to their pregnancy. This study is looking at how effective a workshop that is delivered early in pregnancy, that covers important diet, exercise, and smoking cessation advice, support and referrals, is to improve the health of pregnant women attending a large maternity hospital in South East Queensland.

The overall aim of this study is to examine whether or not a web-based intervention employing a cognitive-behavioural therapy approach, can reduce the risk of suicidal ideation (SI) in young people who have presented to the school counselor for help. Secondary aims are to examine whether or not the intervention can increase coping and problem solving skills and help-seeking (these are measured as a means of understanding the underlying mechanisms that may lead to a reduction in risk). We will also assess the acceptability of the intervention, treatment adherence, how long people remain on the website and whether or not the intervention causes undue distress. Hypotheses The primary hypotheses are that the intervention will: 1. Reduce SI among participants Secondary hypotheses are that the intervention will: 2. Reduce symptoms of depression, anxiety and hopelessness 3. Increase help-seeking 4. Improve coping and problem solving skills 5. Participants will find the receipt of this intervention acceptable, and 6. The intervention will not cause undue distress.

A study to assess the effectiveness of oral tranexamic acid to placebo in reducing the amount of blood loss from lower gastrointestinal bleeding, and to reduce the amount of blood needed to be transfused.
