Summary
Diabetics commonly suffer from gastrointestinal symptoms such as bloating and nausea. We have preliminary evidence that interstitial cells of Cajal (ICC), which are essential for normal gut motility, are particularly vunerable to damage in diabetes. The goal of this study is to determine how the loss of ICC in diabetes leads to delayed gastric emptying. Our overall aim is to identify potential therapeutic targets for improved treatment of diabetes-related gastrointestinal motility disorders.

Summary
Cell coupling through gap junctions is said to play an important role in regulating blood flow and blood pressure. However data obtained from mice, in which specific gap junctions are deleted, may be compromised by compensatory changes in other junctions. We have validated a new method for rapidly and reversibly altering gap junctions in adult mice with oral sugar. This technique will enable us to directly determine whether interference with cell coupling affects blood flow and blood pressure.
Myoendothelial Gap Junctions: Their Composition And Role In Vasodilator Responses Attributed To EDHF

Summary
Cardiovascular disease, including coronary heart disease and stroke, continues to be the major cause of death in Australia and hypertension is a significant risk factor. The endothelium, which lines blood vessels of all sizes, is critical to the control of blood flow to the organs of the body. Endothelial cells release factors which can cause blood vessels to constrict or to relax, thus decreasing or increasing blood flow, respectively. Under normal conditions, the endothelium is more important ....Cardiovascular disease, including coronary heart disease and stroke, continues to be the major cause of death in Australia and hypertension is a significant risk factor. The endothelium, which lines blood vessels of all sizes, is critical to the control of blood flow to the organs of the body. Endothelial cells release factors which can cause blood vessels to constrict or to relax, thus decreasing or increasing blood flow, respectively. Under normal conditions, the endothelium is more important as a source of relaxing factors, while under hypertensive conditions, the balance is shifted in favour of the release of constricting factors. Thus, restoration of the vasodilatory function of the endothelium is seen as an important new therapeutic target in the treatment of vascular disorders. Present data suggests that the action of one of the major endothelial derived vasodilatory factors, the so-called endothelium-derived hyperpolarizing factor, EDHF, requires the presence of particular structures within the vascular wall, but little is known about the molecules of which they are comprised. We have identified two unique situations, during development and during hypertension, when these structures are present in vessels in which they are absent in normal adults. We will use gene microarrays to identify the specific molecules involved in these structures and use physiological studies to test the role of these proteins and structures in vasodilatory responses. The results of these studies may identify new targets for therapeutic intervention to restore the action of EDHF in hypertension.Read moreRead less
Improving Outcomes For People With Cancer: Consultation Skills Training With Oncologists

Summary
Each year approximately 30,000 Australians die from cancer and 65,000 new cancers are diagnosed. Despite much research for a cure for cancer, the incidence and mortality from cancer has not changed. New treatments now cause people with cancer to live longer with the disease, so we now need to focus on efforts to optimise the quality of life of these people. Although the emotional burden on patients and families is recognized, there is a sense that this is an inevitable by-product of the disease ....Each year approximately 30,000 Australians die from cancer and 65,000 new cancers are diagnosed. Despite much research for a cure for cancer, the incidence and mortality from cancer has not changed. New treatments now cause people with cancer to live longer with the disease, so we now need to focus on efforts to optimise the quality of life of these people. Although the emotional burden on patients and families is recognized, there is a sense that this is an inevitable by-product of the disease and its management in existing clinical systems. However, this does not need to be the case. There is now ample evidence that the way that doctors interact with their patients can effect the accuracy of diagnosis and prognosis, as well as patients' satisfaction, adherence with treatment instructions and quality of life after being diagnosed with cancer. Both patient advocate groups and clinicians have called for further training for doctors to effectively manage psychosocial aspects of cancer care, however, despite this support, there have been few opportunities for such training in Australia. We have developed an innovative consultation-skills program for oncologists. So that the effectiveness of the project can be evaluated, it will be implemented as a randomised controlled trial with oncologists from major Australian cancer clinics being randomly allocated to an intervention or control group. The training program will be delivered by videoconferencing, to overcome many of the barriers that have impeded busy clinicians from participating in previous training programs. This is the first international study to use videoconferencing between remote locations for this type of consultation skills training. A variety of measures will be used to evaluate the impact of the training, including patients' quality of life, anxiety, depression and perceived needs, and oncologists' burn-out.Read moreRead less
Communication Of Genetic Information In Families: A Randomised Controlled Trial Of A Genetic Counselling Intervention.

Summary
The amount of genetic testing information available to Australians has exploded as a result of the human genome project. Our multi-disciplinary team will investigate the most acceptable and feasible way for important genetic information to be transmitted in families. This study will be a world first trial of a genetic counselling intervention which aims to help patients and health professionals communicate life-changing information in families where there is a serious genetic condition.

The condition disturbs thinking and problem solving. Ultimately, these problems manifest in impaired verbal communication. Communication problems following traumatic brain injury can make critical relationships-such as father, husband, and employee-impossible to sustain. Those affected are socially inappropriate and uncomfortable to be around, which causes a lifetime of lost friendships, unemployability, and social isolation. Minimisation of these lifelong effects is of the utmost importance to the health of those affected, and is critical to reducing the economic burden of the condition. Two approaches have been shown to improve the communication of those with traumatic brain injury. Training in social skills is helpful, as is training partners to deal with difficult communication behaviours. However, to date, no research has concurrently studied these two approaches to rehabilitation. Consequently, it is unknown whether best results are achieved with either one of the two methods, or both. The present project uses a clinical trials approach in an innovative evaluation of three methods of treating those with traumatic brain injury compared with a control group. The trial involves the conceptual advances of including cost effectiveness of treatment as an outcome measure, and inclusion of advanced methods to measure the intricacies of verbal communication. The multidisciplinary team of Chief Investigators has international track records in the requisite disciplines for the study of traumatic brain injury and its rehabilitation.Read moreRead less

Best practice treatments for chronic stuttering in adulthood and late adolescence stop or reduce stuttering with a systematic process of speech restructuring. However, speech restructuring treatment for chronic stuttering is specialised and resource intensive. Probably half of Australians with chronic stuttering cannot access such specialised treatment services because of distance and lifestyle factors, and because clinicians do not have the resources to provide the treatment. These problems present a research challenge. The present project aims to meet this challenge by developing an innovative treatment model for adults who stutter based on telehealth. This treatment model will make the treatment accessible to all rural and urban dwelling patients with chronic stuttering, and will make the treatment deliverable by every clinician. The research will have significant impact for many end users.Read moreRead less
