Summary
Anxiety and depressive disorders account for 58% of the burden of mental disorders, or 7.5% of the burden of human disease. Internet treatments for the individual disorders are effective but require careful diagnosis. We intend to develop and prove the effectiveness of a transdiagnostic Internet treatment program that will be easily used by primary care clinicians. We will disseminate and evaluate the developed and proven program to general practitioners and psychologists.

Recent international research is focused on identifying mechanisms underlying effective treatments of PTSD, in an attempt to understand both the processes that maintain PTSD, and to help target more precise interventions to prevent chronic PTSD, a disabling condition that creates an enormous economic burden on health and compensation systems. This project will be the first study to identify the neural mechanisms underlying effective exposure-based treatment of PTSD. Exposure-based treatments are the current treatments of choice for PTSD, with several studies showing them to be highly effective in treating PTSD. Yet, the mechanisms and agents of change underlying this effective treatment remain unknown. Exploring the neural networks associated with effective treatment and symptom change will help identify and elucidate the mechanisms underlying exposure treatment. This has critical clinical implications, enabling insight into biological mechanisms underlying PTSD, more precise identification of populations that are less responsive to standard exposure-based treatments, and eventually will lead to better targeted and more effective treatment of chronic PTSD.Read moreRead less

Current trends suggest that the national cost of medical treatment of reflux will become unaffordable unless new management or preventative strategies can be developed. Presently, surgery is the only treatment which can cure reflux. Laparoscopic fundoplication has recently become an acceptable, low morbidity keyhole surgical treatment for this problem. However, research is essential to develop a procedure which optimizes the outcome for patients undergoing surgical management of reflux, and minimizes the risk of complications. This may provide a better alternative to long term management with acid suppressing medication, and could eventually achieve long term savings to the nation's health budget. Since 1994 research conducted at the Royal Adelaide Hospital has evaluated a range of different key hole operations aimed at improving the outcome for patients undergoing surgery for gastro-oesophageal reflux. Over 100 patients have been entered into each of the following clinical trials: total fundoplication with or without division of the short gastric vessels, total versus anterior partial fundoplication and posterior or anterior hiatal repair. Further trials will compare a lesser degree of anterior partial fundoplication with total fundoplication. A common research protocol has been developed and applied to all of these trials. This involves the use of double blind randomised methodology, with independent follow-up obtained by an independent investigator. These trials will determine the best surgical technique for the surgical correction of reflux, and this should lead to a more widely accepted surgical alternative to existing non-operative strategies for pathological reflux.Read moreRead less

Summary
Anxiety disorders affect around 5-10% of adolescents and are associated with a range of adverse consequences if left untreated. The majority of young people with anxiety disorders do not seek nor receive treatment. This may be due partly to the perceived stigma of attending a mental health clinic and logistic problems of attending therapy. A challenge is to identify ways in which treatment can be made more accessible to adolescents in need, particularly those in rural and remote areas.

The majority of young people with anxiety disorders do not seek nor receive treatment. This may be due partly to the perceived stigma of attending a mental health clinic and logistic problems of attending therapy. A challenge is to identify ways in which treatment can be made more accessible to adolescents in need, particularly those in rural and remote areas. Contrary to original beliefs, evidence shows that the internet can be used to deliver effective psychological therapies for a range of mental health problems, including anxiety disorders. So far this research has focused on adults, but adolescents may be in a particularly strong position to benefit from these forms of therapy, being experienced users of internet resources. This research investigates the effectiveness of internet-based cognitive-behaviour therapy (CBT) in the treatment for anxiety disorders in adolescents. Recently we have piloted CBT for anxious children that combines clinic and internet therapy, with half the therapy sessions in the clinic and half over the internet. Pilot data show that clinic + internet therapy produced significant reductions in anxiety and is almost as effective full clinic-based therapy. The proposed research builds on our pilot work by evaluating the effectiveness of a more extensive internet-based therapy in which all sessions are completed using the internet and with an older age group. The research also examines the factors that predict which young people will respond most positively to the intervention so that the treatment can be matched to those most likely to benefit from it in the future. The aim is to develop an effective internet-based treatment for adolescents with anxiety disorders that is easily accessed and suitable for use in rural and remote populations, requiring minimal face-to-face therapist contact.Read moreRead less

The current management of stroke patients is inadequate in improving patients' walking ability to a level that promotes independence in the community, as it does not address the impairments at the physiological level necessary to implement significant change. A relatively new approach to walking following stroke is the use of treadmill walking. However, this form of training does not address the weakness following stroke. Therefore we propose to demonstrate the efficacy of a relatively new modality 'treadmill training with power training', at higher intensity over a greater number of sessions than would be received currently with 'usual care' or treadmill training only. To ensure that persons continue to maintain the level of improvement from an intensive exercise program, we will also implement a behavioural change for long-term maintenance of exercise behaviour in a less supervised environment. A randomized, single-blinded, control trial will be used. Subjects will be randomly allocated to 'treadmill training + power training', 'treadmill training', or usual care (i.e. control). Subjects in the two training groups will also receive 'usual care'. Subjects in the treadmill and treadmill + power training groups will attend training sessions for 10 weeks, with 3 sessions per week. Subjects will then be provided with a home exercise package to continue with their exercises. The findings from this study are critical in identifying whether, by addressing the 3 major impairments following stroke at doses which are known to produce physiological change in other frail populations, the stroke patient can achieve independence in walking and walk sufficient distances, both of which are important to the stroke patient.Read moreRead less

As there is presently no cure for knee arthritis, strategies that slow progression of the disease will reduce the personal and societal burden of arthritis. Most research has focussed on drug therapies, which are effective in reducing pain and disability but have side effects and are expensive. Insoles worn inside the shoes are a simple, cheap, self-administered intervention with the potential to slow disease progression in certain patients, in addition to managing symptoms. However, to date there has been little quality research investigating the effectiveness of insoles in knee arthritis. This study aims to see whether 12 months of wearing insoles can lead to improvements in knee pain and function and slow disease progression in 200 people with knee arthritis. It will use state-of-the-art technology, magnetic resonance imaging, to measure changes in the amount of knee cartilage. This research is timely and the findings will be of major significance as there is increasing world-wide attention on slowing progression of knee arthritis. Insoles are one of the few non-drug therapies with the potential to influence both symptoms and disease progression. If the results show that insoles are beneficial, then this research will: 1. Better inform clinical guidelines to firmly recommend insoles to manage knee arthritis 2. Provide the basis for developing education strategies for health care practitioners and patients about the benefits of insoles 3. Provide the impetus to make insoles more readily available directly to patients 4. Ultimately lead to better patient outcomesRead moreRead less

The main symptoms are breathlessness, usually during sleep or upon exercise, and fatigue. Recent research has identified that sleep apnoea, a condition that occurs in about 50% of subjects with heart failure, is likely to be responsible for these symptoms. Moreover, treatment specifically aimed at sleep apnoea, namely continuous positive airway pressure (CPAP) delived via a small electric pump and nasal mask worn during sleep, may also improve the symptoms of heart failure. The study will involve subjects with stable heart failure on optimal drug treatment who have evidence of obstructive sleep apnea on an overnight sleep study. Obstructive sleep apnoea (OSA) is a condition in which the throat intermittently narrows or blocks during sleep (often associated with snoring) causing cessation of airflow or apnoeas. Associated with the apnoeas are vigorous efforts by the chest muscles to breathe (creating negative vacuum-like pressures within the chest - and around the heart) at a time of falling oxygen levels. Previous research has suggested that these obstructive apnoeas are detrimental to the heart. Volunteers will be randomized to either a control or a CPAP treated group for a three month period. The control and CPAP groups will receive intensive advice about good eating and sleeping habits as weight gain and sleep loss are factors known to aggravate heart failure and obstructive sleep apnoea. In addition to the lifestyle advice, the CPAP group will also be treated with nasal CPAP. The variables which we will measure include severity of sleep apnoea, exercise capacity, heart function at rest and symptoms. Symptoms will be measured using 4 very detailed and validated questionnaires.Read moreRead less

Summary
We will conduct clinical trials to find an effective, simple and cheap oral alternative to injected penicillin for skin sores which could become the universal standard of care whether the patient is in Melbourne or Milingimbi. It would also likely be adopted by the World Health Organization as a standard of care for developing countries. This would lead directly to a reduced burden of skin sores and their complications. It would also open the way for studies to explore even simpler regimens.

Although most women and their babies do well, pre-eclampsia, defined as high blood pressure together with protein in the urine is a more serious problem. Severe pre-eclampsia is associated with 10-15% of maternal deaths. Fetal and newborn baby deaths are also increased. Mother and baby morbidity is high principally due to the associated complications in pregnancy, increased obstetric interventions, fetal growth restriction and preterm birth. As yet we have no safe and effective way of preventing this life threatening condition. Aggregation of platelets (involved in blood clotting) is known to be part of the disease and could lead to the disturbances in the circulation of the mother and the placenta. Antiplatelet agents, low dose aspirin in particular, might prevent or delay the development of pre-eclampsia. Some trials and a Cochrane systematic review of all trials (involving over 30,000 women) suggest that pre-eclampsia, preterm birth and perinatal death could be reduced. However, it is still not clear which women will benefit, when in pregnancy the treatment should start and what dose of aspirin is both effective and safe. This proposed individual patient data review in which data on all women who have been entered in trials is gathered from the original investigators, including missing information on potential harms. This proposal represents a good investment of resources to obtain the information needed by women and health professional to make decisions about the use of aspirin. International investigators from all the primary trials have already formed a collaboration to oversee the project: the Perinatal Antiplatelet Review of International Studies (PARIS) Collaboration Furthermore, working through an international collaboration will ensure the highest quality in data availability, as well endorsement and implementation of the results in practice.Read moreRead less
