Summary
Osteoporosis is a largely preventable disease yet 1 in 10 Australians have osteoporosis. Every year >64,000 osteoporotic fractures occur, which is one every 8.1 minutes and women are three times as likely to have the disease than men. The Bone and Calcium Research Group at the University of Western Australia, is studying how to prevent osteoporosis in elderly women. This study is called the Calcium Intake Fracture Outcome Study or CAIFOS.

Every year >64,000 osteoporotic fractures occur, which is one every 8.1 minutes and women are three times as likely to have the disease than men. The Bone and Calcium Research Group at the University of Western Australia, is studying how to prevent osteoporosis in elderly women. This study is called the Calcium Intake Fracture Outcome Study or CAIFOS. During 1998, 1,500 women were recruited to study whether a daily calcium supplement for 5 years helps to prevent fractures compared to a diet without a supplement. To do this only half of the women were given calcium supplements and the other half were given matched placebo tablets. Each year the study participants are reviewed and asked whether or not they have broken any bones and have other measurements to monitor their bone health and overall health. The subjects are entering their last year of treatment and will finish the study during 2003. At this appointment all subjects will undergo the same series of measurements that they had at the beginning of the study to determine whether or not they have fractured any bones, improved their bone mass and overall health during the treatment stage. The main outcome of the study is to determine whether calcium is useful as a supplement to prevent osteoporotic fracture in elderly women. If this study finds that fewer women fractured in the calcium treated group compared to the non treated group, given that both groups were similar to begin with, we can say that supplementation with calcium prevents fractures. Thus, public health messages about preventing osteoporosis will be able to direct the community to take supplements to prevent a disease that creates pain and disability in later life. The advantage of this study is that it is studying other aspects of these women health, so we can determine whether the calcium is safe to use and improves people's quality of life.Read moreRead less
Good nutrition is a vital element in a healthy start to life. Determining the correct foods to ensure that pregnant women meet both their needs as well as those of their new baby can be very confusing. Do I need to take iron supplements? How can I ensure I get enough iodine?

Healing Pressure Ulcers: Efficacy And Cost Effectiveness Of Nutrition Interventions In The Treatment Of Pressure Ulcers And Chronic Wounds

Summary
It makes sense that good nutrition should help with healing of pressure ulcers, yet there is little evidence of what type of diet or nutritional supplements, if any, can assist in pressure ulcer healing. This research program will investigate the value of different types of diets and nutritional supplements in the healing of pressure ulcers, in comparison with other forms of treatment and whether this is a cost effective approach.
Omega 3 Fats To Reduce The Incidence Of Prematurity: The ORIP Trial

Summary
The most significant perinatal problem in the world today is early preterm birth with its consequent threat to life and life-long health in survivors. Fish oils have been suggested to overcome this problem. Encouraging results have been obtained from small trials that need substantiation in a large well designed trial. The ORIP trial, involving approximately 5510 women, will provide a definitive answer to the question of whether maternal fish oils supplementation reduces early preterm birth.
Testing The Effect Of Long-chain Omega-3 Polyunsaturated Fatty Acids On Cognitive Ageing In The Elderly

Summary
The ageing profile of our population holds challenges for society, with some of the major impact due to loss of independence and quality of life in older people, arising from decline in cognitive functioning. Evidence suggests a benefit of Omega-3 fatty acids on cognitive functioning in older people but claims that Omega-3 slows cognitive decline have not been adequately tested. This study tests the effect of Omega-3 supplementation on cognition in healthy older people, over an 18-month period.
Does N-3 LCPUFA Supplementation During Pregnancy Improve The Intelligence Quotient Of Children At School Age?

Summary
Pregnant women in Australia are being inundated by advertisements from health food companies and health organisations to increase their intake of fish oil to ensure that their babies will maximise their chance of achieving a high IQ. Our study will provide the first solid evidence to test whether these claims are true. This will help us frame nutritional guidelines in pregnant women.
Many dietary recommendations are inconsistent and based on inadequate research based on 1970s technologies. As a result, the current recommendations are almost impossible to meet from foods, without nutritional supplements. Using state-of-the-art technology, this research aims to redefine the nutritional requirements omega-3 long chain polyunsaturated fatty acids, iron and iodine, as well as the correct balance of energy producing macronutrients in the diet of mothers and their children.
Pharmacological Effects Of Oral L-citrulline And Tetrahydrobiopterin In Patients With Peripheral Artery Disease

Summary
Citrulline, named after citrullus vulgaris, the watermelon, is a precursor of arginine. Arginine is converted to protective nitric oxide (NO), which is decreased in cardiovascular diseases (CVD). Although arginine supplementation can increase NO availability and improve vascular function it is hampered by a low availability. In contrast, Citrulline is highly available and converted to Arginine. Therefore, this project will explore the therapeutic effects of Citrulline in patients with CVD.
Long-term Follow-up Of Children Born Preterm Who Received High Dose DHA: The DINO Trial Follow-up.

Summary
Children born prematurely are more likely to need help at school and to repeat a grade. One of the factors that may be responsible for the poor development of children who were premature may be the lack of an omega-3 fatty acid, called DHA. We have done a study in which feeds of premature infants were supplemented with DHA at a level equivalent to what a baby would recieve in the womb. We now want to see if these children have improved development at school age.
