It will also examine rural residents' perceptions of their mental health needs and their access and utilisation of health services. The study will be conducted in 3 rural Area Health Services in NSW (Greater Western,Hunter New England and North Coast) comprising 70% of the rural population of NSW. These health regions encompass rural, remote and coastal NSW. We aim to conduct the mail and telephone survey on adults residing in 4000 households across the 3 regions. Unique aspects of the study include: i) Examination of a diverse range of rural communities which will provide the opportunity to investigate the influence and interaction of specific community characteristics on mental health. These community factors will include social and economic factors, severity of rural environmental stress (eg drought), and the levels of access to health and other services. ii) Focus on the household and its members so as to examine the mental health needs of family groups in rural communities. This cross-sectional study will form the baseline for a longitudinal study investigating the changes experienced by rural families over time and the impact of such change on mental health outcomes.Read moreRead less
The Role Of Oxygen Sensing In The Regulation Of Trophoblast Invasion

Summary
Normal fetal development requires the placenta to successfully invade the mother's uterus so that the baby can be appropriately nourished. It is well known that a failure of normal placental development is associated with two major complications of pregnancy: pre-eclampsia and intrauterine growth restriction. This study is designed to discover whether placental cells have special oxygen sensing mechanisms that help them home in to areas where there is high oxygen.

The proposed online system will provide medical advice and diagnosis, consumer health care information services, support groups, information and distance education for those working in the health care as well as the community and assistance in the operational and medical decision-making process. Less expensive health care personnel should be able to use the system with little training in remote and rural areas. This project will generate knowledge about the practicality of low cost but highly effective e-health system. It will be easier to disseminate health care information and health evaluation processes to patients, doctors, nurses and other health care workers. It will also be possible to obtain information about image resolution, suitable compression algorithms and compression levels for different diseases pathologies.Read moreRead less
Evaluation Of Internet-based, Cognitive Behaviour Therapy For The Treatment Of Anxiety Disorders In Adolescents

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

A number of key nutritional factors including calcium and dietary protein intake are known to be important in the development of osteoporosis. This proposal will test the hypothesis that human bone cells express a protein which senses calcium and amino acids, the calcium-sensing receptor, and thereby respond to nuritional signals arising from the presence of calcium ions and amino acids in plasma. Furthermore, we propose that by promoting osteoblast proliferation, maturation and survival, the calcium sensing receptor acts as the key molecular mechanism by which dietary calcium and protein promotes bone formation.These studies have potential to explain relationships between bpne resorptive activity, which raises local calcium concentrations, and bone formation activity and the coupling of bone forming and resorbing activity. These studies have the potential to explain the positive effects of calcium and protein intake on bone mass and may also shed light on the regulation of the coupling between osteoblastic and osteoclastic activityRead moreRead less

Establishing the reliability of diagnosis and other related assessments, and identifying which functions can confidently be carried out via video conferencing, is one step towards extending the availability of this service to rural and remote communities. Access to accurate diagnosis and assessment of cognitive impairment is an important step in the management of dementia, Alzheimer's disease and other associated disorders. High level expertise, such as that offered by a specialist Memory Disorder Clinic, is particularly important if there is uncertainty about the diagnosis, or if the prescription of cholinesterase inhibitors and associated medications are being considered. It was estimated that in 2005 there were 52,000 people diagnosed with dementia in Australia and by 2050 there will be an additional 175,000 cases each year. For the vast number of people who will be affected by dementia, early detection and intervention will play an important role in their healthy ageing experience. Access to accurate diagnosis and advice as a function of detection and intervention is often not as freely available to people in rural areas. The experience of travelling long distances for assessment can be detrimental to the emotional well being of people who may have dementia. Access to geriatrician services in a local rural area is an important element to maintaining their sense of well being. Geriatricians are not commonly available in rural areas which means current access to specialist diagnosis and assessment is either a missed opportunity or involves extensive travel. Internationally, there are many individuals living in remote regions with no access to geriatrician services, or reliable cognitive assessment. This study will inform similar experiments in other cultural settings.Read moreRead less

Summary
Parkinson's Disease affects a person's ability to speak clearly. Speech pathologists can provide effective treatment for this speech disorder. Access to a speech pathologist, however, is difficult for many people with Parkinson's Disease due to their physical difficulties and the limited availability of speech pathology services in rural areas. This study demonstrates the use of telerehabilitation to deliver speech treatment to people with Parkinson's Disease in their own homes via the Internet.
Does Remote Ischemic Preconditioning Induce Protective Mitochondrial Function In Congenital Heart Defect Repair Surgery?

Summary
The body's own protective mechanism against injury due to reduced blood flow (ischemic preconditioning) has been studied for over 2 decades, yet the clinical benefits have not been realised until recently . We have previously shown that this innate protection can be induced without drugs in children having heart surgery. We will extend these findings to determine the mechanism of protection, develop a method to monitor this in blood cells and see if this is related to post-operative outcomes.
