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.

Summary
This study is needed to determine whether a common clinical practice long-term antibiotic treatment for children following urinary tract infection (UTI) - is safe and effective in preventing further UTI and if so, whether all appropriate children are being treated. UTI will affect about 10% of Australian children by high school age (88,000 children per year). Because UTI may damage the kidneys, the management priority for children with UTI has been prevention of further infection.

UTI will affect about 10% of Australian children by high school age (88,000 children per year). Because UTI may damage the kidneys, the management priority for children with UTI has been prevention of further infection. Currently this means the identification of children thought to be most at risk of recurrent UTI by renal tract imaging. Those found to have reflux of urine from the bladder to the kidney (present in about 30% of those with UTI) are then placed on antibiotics fro 2-5 years. Unfortunately there has never been a properly designed trial to test whether antibiotics do really prevent UTI and if so, whether children with reflux are the appropriate and only group requiring treatment. Long term antibiotics may in fact do more harm than good because of side effects like skin, bowel and blood problems and because resistant bacteria may develop. The design of this study involves the random allocation of placebo or antibiotic (cotrimoxazole, the usual antibiotic given in this case) to about 800 children after their first symptomatic UTI. These children are treated and followed for one year to determine the rate of futher UTI in both groups. Any difference in outcome between the two groups of children will be because of the antibiotic treatment. This study may prove long-term antibiotics are ineffective and therefore should not be routinely used. In this case investigation of children to detect vesicoureteric reflux would serve little purpose and should be abandoned. Alternatively antibiotic treatment may be shown as effective treatment for preventing further UTI and in this case the study will clearly identify those children who will benefit.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.
