Summary
Female sexual dysfunction (FSD) is frequently reported with selective serotonin reuptake inhibitor (SSRI) therapy and venlafaxine, these being the most common antidepressants used by Australian women. We have shown that testosterone therapy significantly improves sexual function in women with FSD. However SSRI-users have been excluded from these past studies.

Vascular Dementia (VaD) is the second most common cause of dementia after Alzheimer's disease. In fact, it may be a preventable cause of dementia. Yet it has been relatively neglected by researchers until the last decade, which has seen an upsurge of interest in this disorder. There is no consensus on the criteria for dementia.

In fact, it may be a preventable cause of dementia. Yet it has been relatively neglected by researchers until the last decade, which has seen an upsurge of interest in this disorder. There is no consensus on the criteria for dementia. The profile of early cognitive impairment due to vascular factors is still poorly understood, and the longitudinal course of VaD as defined by modern criteria has not been studied. There have been few studies of the progressive changes in MRI in patients with cerebrovascular disease. The overlap of VaD and Alzheimer's disease (AD) remains a problem for taxonomists and clinicians. One approach to the study of VaD is to examine a high risk group of subjects longitudinally to determine the early features, the risk factors and progressive changes. With this in mind, we began studying a cohort of stroke patients who are at high risk of VaD, in 1997-1999, and are following them longitudinally. The follow-up is now in its third year, and three neuropsychological assessments and two MRI-MRS scans have been performed. We propose to extend the follow-up to 5 years, with repeat neuropsychiatric, neuropsychological and MRI-MRS investigations, and wherever possible to necropsy, to determine the nature of vascular pathology that underlies cognitive impairment. Our cohort of stroke patients is arguably the most comprehensively assessed such cohorts internationally, and presents an excellent opportunity for a long-term follow-up study.Read moreRead less
Identification Of Heterogeneity In Vasodilator Function In Human And Rat Resistance Vessels: Potential Drug Targets?

Summary
The balance between the ways that blood vessels decrease in size (constrict) and increase in size (dilate) determine how blood vessels normally function. There are many differences in the ways that blood vessels control this balance in different parts of the body. Such differences are altered in vascular diseases, such as hypertension and diabetes, which are prevalent in obesity, such that constriction generally outweighs dilation. However, what these differences are and how they occur are not w ....The balance between the ways that blood vessels decrease in size (constrict) and increase in size (dilate) determine how blood vessels normally function. There are many differences in the ways that blood vessels control this balance in different parts of the body. Such differences are altered in vascular diseases, such as hypertension and diabetes, which are prevalent in obesity, such that constriction generally outweighs dilation. However, what these differences are and how they occur are not well understood. While current drugs for treating vascular disease either reduce vessel constriction or increase dilation, they are not specific for individual arteries; a situation that would allow us to control vascular diseases in a very specific manner. Recently, we have described differences between the ways that individual vessels are controlled. These changes relate to differences in the way that different vessels dilate. AIMS - To further understand normal blood vessel function and the changes that occur in blood vessels in cardiovascular disease, with a focus on the ways that blood vessels dilate in normal states and in obesity-related diseases, such as in hypertension and diabetes. - The eventual aim is to identify the specific ways that arteries function, so that artery-specific drug targets can be identified to treat disease-related changes in cardiovascular disease in a very specific manner. EXPECTED OUTCOMES This project will contribute to understanding blood vessel function in health and disease. The expected eventual outcome is the identification of the mechanisms that underlie the function of different arteries in different parts of the body, so that specific individual vessel function can be targeted to treat vascular disease. Additionally, this work will also verify the relevance of the diet-induced obesity animal model, in terms of the characteristics and causes of human obesity and related cardiovascular disease.Read moreRead less
A Trial Of A Multidisciplinary, Group Based Intervention To Meet The Needs Of Men With Prostate Cancer

Summary
This study will test an innovative approach to meeting the physical and psychosocial needs of men with early stage prostate cancer using a randomised controlled trial. This novel approach involves a combination of individual and group-based consultations which encourages peer-to-peer support, promotes self-care and enhances appropriate multidisciplinary referrals and communication. It provides a new model of care for patients with chronic diseases that can be translated into clinical practice.
The Role Of Snoring Vibrations In The Pathogenesis Of Early Carotid Artery Atherosclerosis

Summary
Habitual snoring is a very common problem in the adult population, with a prevalence of between 20-40%. Increasingly it is now recognised that snoring may be an independent risk factor for the development of stroke. In this proposal, we will explore the hypothesis that chronic snoring transmits a pressure wave through the tissues of the neck to the carotid artery which may damage the artery wall and subsequently lead to stroke. This may lead to new strategies to treat habitual snoring.

Summary
Obsessive-compulsive disorder (OCD) is a psychiatric disorder that affects up to 3% of the general population. People with the disorder experience unpleasant intrusive thoughts that they find distressing and have a strong urge to perform particular behaviours. Fears about fire and burglary are common and excessive checking of electrical appliances and locks can take many hours a day. Checkers represent one of the largest OCD sub-groups.

People with the disorder experience unpleasant intrusive thoughts that they find distressing and have a strong urge to perform particular behaviours. Fears about fire and burglary are common and excessive checking of electrical appliances and locks can take many hours a day. Checkers represent one of the largest OCD sub-groups. Because of the time-consuming nature of the condition, social and occupational functioning is often severely restricted. Many sufferers will also experience extreme social isolation and depression. The World Health Organisation ranks this disorder as 20th among all causes of burden of disease. The development of effective interventions could substantially reduce the economic and social burden of this disabling anxiety disorder. The aim of this project is: (1) to compare the therapeutic efficacy of a new treatment approach (Danger Ideation Reduction Therapy) with that of Exposure and Response Prevention (ERP); It is hypothesised that: (1) subjects who receive 12 sessions of DIRT will show greater post-treatment and follow-up reductions in symptomatology than subjects who receive ERP.Read moreRead less
