The study focuses on patients admitted to hospital with cardiovascular diseases. The cardiovascular system includes the heart and blood vessels that carry blood around the body. Smoking is one of the major risk factors for cardiovascular disease and following diagnosis individuals continue to smoke. We aim to particularly focus on these individuals for intensive treatment via a smoking cessation program. A specially trained Registered Nurse will undertake motivational interviewing techniques that consider the person’s readiness to change smoking habits and promote lifestyle changes. For further support a cardiologist and psychologist will be available for consultation.

Research question: To determine whether the addition of positive expiratory pressure (PEP) improves uniformity of deposition of an inhaled aerosol in upright sitting in healthy participants. Methods: Inclusion criteria: greater than or equal to18 years of age, normal lung function. Participants will inhale a 4mL radioaerosol in two stategies in random order throughout the nebulisation period of 20 minutes: 1. Standard nebulisation period of 20 minutes, or 2. Nebulisation period of 20 minutes with the addition of a PEP device. After each nebulisation a gamma camera will perform a 20-minute deposition scan incorporating a transmission scan to outline the three-dimensional margin of the lung fields. This data will be reconstructed to determine the distribution of the deposited radioaerosol in the lungs. A 15% improvement in uniformity of deposition is the proposed minimum difference that would make further investigation of the PEP strategy worthwhile in patient populations. Significance of project: In many patient populations (eg, cystic fibrosis, HIV and bronchiectasis), the pattern of deposition of inhaled medication is poor and non-uniform. The ability to deliver a drug more uniformly to the lung using the addition of PEP may have a significant impact on treatment efficacy for people with lung disease. Data from healthy participants will aid interpretation of subsequent studies in patients.

The aim of the study is determine whether the administration of polyethylene glycol (Movicol) to post operative total hip and total knee replacement patients results in faster return to normal in the intervention group.

The primary objective is to evaluate the safety and efficacy of the Large Diameter Advanta V12 Covered Stent for treatment of native and recurrent aortic coarctation of the aorta in selected children and adolescents.

This study aims ot assess the effectiveness of ketamine as an pain reliever when administered into the nasal passages in doses that do not produce sedation or anaesthesia in a group of paediatric emergency department patients coming to hospital with moderate to severe pain. We hypothesise that ketamine will reduce pain effectively without significant sedation at the proposed dose. The data from this study will be used to calculate sample size and design a study comparing the effective dose of ketamine to other pain relivers currently administered by the nasal route to children.

Our national study aims to improve the management of acute exacerbations of bronchiectasis in children, a lung condition that is common in Indigenous people worldwide, and also occurs in non-Indigenous people. This study aims to discover whether treating acute exacerbations of bronchiectasis with oral antibiotics is effective at resolving the exacerbation more quickly than not treating with antibiotics. The results of this study will impact on national and international guidelines and substantially advance knowledge on exacerbations of childhood bronchiectasis.

Our national study aims to improve the management of bronchiectasis in children, a lung condition that is common in Indigenous people worldwide, and also occurs in non-Indigenous people. This study aims to discover whether treating respiratory exacerbations with one of two different oral antibiotics is more effective at resolving the exacerbation. The results of this study will impact on national and international guidelines and substantially advance knowledge on exacerbations of childhood bronchiectasis.

We aim to develop alternative treatments in patients refusing CPAP therapy. We hypothesize that 2 months of low-flow oxygen compared with room air, each delivered via nasal cannulae will improve sleep-disordered breathing, hypoxia during sleep, symptoms and maladaptive cardiovascular response in patients with OSA refusing CPAP treatment. Secondly, we hypothesize that patients with higher loop gain will derive a greater benefit (reduction in apnoea-hypopnoea index) from oxygen therapy.

This study aims to determine whether compression garments and self massage can prevent or reduce lymphoedema (fluid retention) following groin dissection for metaststic melanoma. Who is it for? You may be eligible to join this study if you are a male or female aged 18 years and over with confirmed metastatic melanoma. You should be able to attend regular follow-up appointments over a period of 2 years. Trial details. Participants in this trial will be randomly (by chance) allocated to one of two groups. Participants in one group will wear compression stockings 12 hours a day for 6 months and conduct daily self massage for a period of 6 months following post operative removal of drains. Participants in this group will receive 1:1 training in self massage over 3 half hour sessions. They will also receive education and training to ensure they (or their carer) are able to safely put on and remove the compression garment. Participants in the other group will be monitored via 3 monthly assessments. If lymphoedema arises, they will be offered comprehensive treatment (as is standard treatment). All participants will be assessed every 3 months to determine the incidence/severity of lymphoedema and quality of life, and whether this differs between groups.

Macular oedema that is secondary to central retinal vein occlusion (CRVO) has conventionally been treated with laser photocoagulation. The outcomes of this treatment show a slight improvement in visual acuity. Recently various therapeutic agents such as Triamcinolone, Pegaptanib, Bevacizumab and Ranibizumab have been injected intravitreally into the eye. Bevacizumab and Ranibizumab in particular have been shown to reduce macular oedema in the short term, however, repeated injections are required. The Central Vein Bypass Study, where a high intensity laser is used to create an anastomosis between the a retinal and a choroidal vein as a means of bypassing the obstruction to venous flow (L-CRA), is the only study to date that has addressed the causal pathology of macula oedema secondary to CRVO, rather than simply addressing the sequelae of the retinal venous obstruction. Patients who received the L-CRA had significantly improved visual acuity compared to the sham L-CRA treatment group. In this study patients will either be treated with the L-CRA or sham L-CRA. Both groups will receive monthly injections of Ranibizumab for 6 months. Patients will be assessed for a further 18 months, and may/may not receive further injections depending on whether the retreatment criteria have been met. The primary aim of the study is to show that L-CRA treated patients will require fewer Ranibizumab injections in the 12-24 month phase of the study compared to sham L-CRA treated patients. The use of Ranibizumab in the short term and the long term treatment effects of the L-CRA may prove to be an effective treatment for macular oedema that is secondary to CRVO. A recent study showed that 56% of patients had persistent macular oedema requiring an average of 5.9 injections in the 4th year. The study protocol has been amended to follow the two treatment groups bimonthly or once every four months for a further 24 months. Patients will be assessed according to the retreatment criteria for further injections. The extension study will provide long-term follow up data.
