Summary
For people with type 2 diabetes (T2DM) it is essential that blood glucose levels are managed well to reduce the risk of developing complications. Physical activity is essential for maintaining glucose levels because it helps make the muscles use glucose more effectively. In particular, being active through strength training not only improves blood glucose levels, but can be very effective for maintaining good physical functioning, which is known to be reduced by having T2DM.

Physical activity is essential for maintaining glucose levels because it helps make the muscles use glucose more effectively. In particular, being active through strength training not only improves blood glucose levels, but can be very effective for maintaining good physical functioning, which is known to be reduced by having T2DM. This study builds on our earlier research which demonstrated significantly improved blood glucose levels from a strength training program for older adults with T2DM. The strength training program is to be administered nationally in a research to practice trial (Lift for Life); however, the original research found that those who did not complete the program as it was intended (ie, poor adherence) did not show significant improvements in blood glucose levels. Furthermore, maintenance of strength training exercises after completion of the program was poor and resulted in return of blood glucose levels back to pre-starting levels. In people without diabetes, we have collected pilot data that shows that the use of behavioural strategies based on behavioural theories whereby each person's motivations and barriers are taken into consideration is more effective than the traditional one-treatment-fits-all approach. This study will evaluate the effectiveness of using behavioural strategies for improving adherence and maintenance to the Lift for Life strength training program (Enhanced L4L) for older adults with T2DM compared with the Standard L4L program. It will also follow-up participants 6 months later to determine the extent to which the changes in behaviour can be maintained. The study will provide information that will assist in the design, delivery and uptake of programs to improve treatment strategies in older adults with T2DM through the maintenance of healthier behaviours and lifestyles.Read moreRead less

Summary
Cardiovascular disease is the leading cause of death in Australian women, but is less likely among women who are active. Because women are less active than men, and women with young children are the least active of all, we developed a program to increase postnatal women's physical activity. Women in the pilot study reported high program satisfaction and more physical activity, because the program focused on them (not their kids) and helped them prioritise time for physical activity.

Summary
Glaucoma is a common cause of loss of vision worldwide but we are unable to predict which people are at high risk of blindness. We aim to discover the genetic risk factors for glaucoma. We will use cutting edge genetic technology to assess the whole genome in thousands of patients with glaucoma. We hope to identify important new glaucoma genes, which could lead to the development of diagnostic tests and treatments which will provide the most cost-efficient ways to prevent glaucoma blindness.

Summary
The normal function of the body is maintained by naturally occurring compounds. Some for example affect the heart, fine tuning it to make it beat faster or slower, or beat with greater or less force when required in different situations in health and disease. We were the first to show just recently that a small protein which occurs naturally in the body, called urotensin-II can affect the way the heart beats. We showed that extremely tiny amounts increase the force of the heart beat. Our finding ....The normal function of the body is maintained by naturally occurring compounds. Some for example affect the heart, fine tuning it to make it beat faster or slower, or beat with greater or less force when required in different situations in health and disease. We were the first to show just recently that a small protein which occurs naturally in the body, called urotensin-II can affect the way the heart beats. We showed that extremely tiny amounts increase the force of the heart beat. Our findings indicate that urotensin-II is the most potent heart stimulator identified to date. In patients with heart failure, short term stimulation of heart contraction is beneficial, supplying the heart and other organs with vital oxygen and nutrients. However, in the long term excessive stimulation causes worsening of the patients condition. Very little is currently known about the way in which urotensin-II alters heart function. The goal of our study is to understand the mechanism involved in urotensin-II mediated effects on the heart. This will involve identifying the location of urotensin-II and its receptors in the heart, and determining what signalling changes occur after the interaction of urotensin-II with its receptors. Urotensin-II must first be cleaved from a larger drug. We will determine where in the heart this cleavage occurs and whether the process is crucial to the ability of urotensin-II to stimulate contraction of the heart. Since stimulators of heart contraction are detrimental to patients with heart failure in the long term, we will determine whether these patients have more urotensin-II in their blood than patients who do not have heart failure. If the levels of urotensin-II are higher in heart failure patients, it may indicate a need to interfere with the interaction of urotensin-II with its receptors.Read moreRead less

Summary
There have been few specific studies of the health of women in mid-life. In mid-life, mental health impairment and health problems associated with biological and social transitions (e.g. menopause) are major concerns. National estimates indicate that between 15% and 20% of women in the mid-life age range have experienced a mental illness in the past year.

In mid-life, mental health impairment and health problems associated with biological and social transitions (e.g. menopause) are major concerns. National estimates indicate that between 15% and 20% of women in the mid-life age range have experienced a mental illness in the past year. The proportion of women experiencing a combination of emotional and physical symptoms, frequently associated with the menopause, is likely to be somewhat higher. This proposal involves merging information collected initially from 1981 onwards, with data on the mother's mental and physical health, to be collected in this follow-up. Women in this study (8556) were enrolled at their first obstetrical visit and they have been followed up shortly after the birth, when the child was 6 months, 5 years and 14 years. On each occasion extensive information has been obtained on the mother's mental and physical health, as well as on the child's health and development. This study will examine the chronicity of the mother's mental health symptoms over a 21-year period, and assess the association between her early mental health, the child's health and her current health status. This is the only large Australian cohort study to have followed a sample of women for 21 years. It will permit us to understand more of how women's health changes over time and the factors associated with these changes. It will provide the first large-scale study of factors influencing women's health transition through the menopause.Read moreRead less

The mental health of young people is one such area. Based on data relating to youth suicide, substance abuse, cigarette smoking by females and behavioural or mental health problems in the young, there has been evidence of a marked increase in some important health problems faced by the young. Little is known about the causes of these problems and even less is known about the reasons for the increase. Based on the available evidence, 20-25% of young persons manifest a mental health problem. A second area of marked health deterioration concerns youth (and adult) obesity. Existing research points to the accumulation of cardiovascular risk factors associated with obesity from a very early age. Over 10% of youth are obese and a substantially higher proportion are overweight. There is evidence that the rate of obesity has been substantially increasing. Again little is known about the factors that contribute to obesity or the causes of the increase in the rates of obesity in the population. This proposal is for a 21-year follow-up of a sample of youth first enrolled when their mothers attended for their first obstetrical visit. Using a substantial body of existing data, we propose to examine the changes in levels of mental health and obesity and to identify the factors which contribute to these changes. This study involves the largest Australian cohort ever assembled for such research. The main questions asked in this study concern the impact of the mother's social and economic circumstances, her physical health and well-being, her use of addictive substances (including alcohol, cigarettes, illicit drugs) on the youth's health. We will also examine the association between early indicators of mental health and well-being and subsequent youth health and development.Read moreRead less

Summary
Childhood cancer presents a major life stressor for the entire family. Significant changes to the everyday lives of families, practically, socially and emotionally cause major disruption. There is evidence that this disruption results in isolation and poor communication between family members, anxiety, low self-esteem and school problems for siblings and anxiety, post-traumatic stress symptoms and risk of depression for parents.

Significant changes to the everyday lives of families, practically, socially and emotionally cause major disruption. There is evidence that this disruption results in isolation and poor communication between family members, anxiety, low self-esteem and school problems for siblings and anxiety, post-traumatic stress symptoms and risk of depression for parents. Providing ongoing support to these families is an essential part of care. The Royal Children's Hospital (RCH) Paediatric Oncology Service in Brisbane is the major tertiary paediatric referral centre for Queensland, northern New South Wales and the southwest Pacific. A multidisciplinary team of medical, nursing, and allied health professionals provides care and support to children with cancer, as well as their families. Each year around 100 newly diagnosed patients are cared for. Around 60% of the families cared for by the service live in regional and remote areas. There are a number of challenges which inhibit the equitable provision of specialist health services to these areas including availability of health care professionals and accessibility due to distance, time, cost and transport. For paediatric oncology families, opportunities to receive support are limited. One possible solution is the use of online support mechanisms, such as videotelephony, to facilitate the provision of much needed support to patients, parents, siblings and the family as a whole. The objective of this research is to see if videotelephony can be used to support regional and remote families of the Royal Children's Hospital Paediatric Oncology Service providing indizidualised communication, education, counselling and monitoring. This will present a new and innovative use of videophone technology as well as a new method for supporting regional and remote oncology patients and their families.Read moreRead less
