An initial trial to women at high risk of pre-eclampsia suggest that vitamin C and vitmin E supplements may decrease both reduce the risk of developing hypertension in pregnancy and the risk of the infant being born small for dates. These encouraging results need assessment in the Australian population. This study assesses the value of women taking vitamin C and vitamin E supplements during the antenatal period to decrease the risk of developing hypertension during pregnancy and poor fetal growth. Such an easy and inexpensive therapy, if effective, would be an important advance.Read moreRead less
It has become increasingly evident that damage to the genetic material in cells (DNA) is a fundamental initiating cause of cancer and accelerated ageing. Furthermore it has been shown recently that moderate deficiencies of certain vitamins and minerals can cause damage to DNA at a level that is observed for carcinogenic doses of radiation and toxic chemicals. In addition studies have shown that supplementation with certain vitamins resulted in a reduction of damage to DNA.

Furthermore it has been shown recently that moderate deficiencies of certain vitamins and minerals can cause damage to DNA at a level that is observed for carcinogenic doses of radiation and toxic chemicals. In addition studies have shown that supplementation with certain vitamins resulted in a reduction of damage to DNA. The aims of this research is to determine whether daily intake of a pill containing certain vitamins and minerals causes a reduction in DNA damage in blood cells. The expected ultimate outcome is a cancer prevention strategy based on reducing the risk of damage to DNA.Read moreRead less

Summary
Stroke is one of the most important causes of death and long-term disability in developed countries. Hardening of the arteries (atherosclerosis) is the major cause of stroke and heart attacks. High blood pressure, high blood concentrations of cholesterol, cigarette smoking and diabetes accelerate the formation of atherosclerosis, but they do not account for all strokes and heart attacks caused by atherosclerosis. There is now increasing evidence that high blood concentrations of homocysteine, a ....Stroke is one of the most important causes of death and long-term disability in developed countries. Hardening of the arteries (atherosclerosis) is the major cause of stroke and heart attacks. High blood pressure, high blood concentrations of cholesterol, cigarette smoking and diabetes accelerate the formation of atherosclerosis, but they do not account for all strokes and heart attacks caused by atherosclerosis. There is now increasing evidence that high blood concentrations of homocysteine, a normal protein in the blood, are another major causal risk factor for atherosclerosis (and stroke and heart attacks). Furthermore, blood concentrations of homocysteine can be lowered by about one quarter with simple, safe and inexpensive multivitamin therapy (folic acid, vitamin B12, and vitamin B6). However, despite the potentially massive public health benefits of such a strategy, it remains to be demonstrated in properly designed clinical trials that lowering homocysteine levels in the blood actually prevents stroke and heart attack. The VITATOPS trial is the only ongoing randomised, double-blind, placebo-controlled trial in the world which aims to determine whether multivitamin therapy (folic acid 2 mg, vitamin B12 0.5 mg, and vitamin B6 25 mg) prevents recurrent stroke and heart attacks in patients who have suffered a recent stroke.Read moreRead less

Summary
The VITAmins To Prevent Stroke (VITATOPS) trial is the only ongoing randomised, double-blind, placebo-controlled trial in the world which aims to determine whether multivitamin therapy (folic acid 2 mg, vitamin B12 0.5 mg, and vitamin B6 25 mg) prevents recurrent stroke and heart attacks in patients who have suffered a recent stroke. To date more than 7,500 patients have been randomised. Ongoing support is requested to complete the follow-up of 8,000 patients by middle of 2009.

Summary
The proposed study emanates from a large ongoing epidemiological study on falls and fractures in the elderly (the FREE study). Falls and fractures are major problems in the elderly. This is the genesis for the FREEDOM (Falls Risk Epidemiology: Effect of vitamin D on skeletal Outcomes and other Measures) intervention study. The FREEDOM study will evaluate the effect of a public health strategy to reduce falls and fractures in older people living in residential care (namely appropriate sun light e ....The proposed study emanates from a large ongoing epidemiological study on falls and fractures in the elderly (the FREE study). Falls and fractures are major problems in the elderly. This is the genesis for the FREEDOM (Falls Risk Epidemiology: Effect of vitamin D on skeletal Outcomes and other Measures) intervention study. The FREEDOM study will evaluate the effect of a public health strategy to reduce falls and fractures in older people living in residential care (namely appropriate sun light exposure and calcium supplementation) in a randomised trial. The primary endpoints of this study will be reduction in falls and change in vitamin D levels. Other endpoints will be change in motor function, mood, bone turnover and fracture incidence. The proposed public health strategy to be examined is readily transferable to routine practice and would have very good feasibility for easy implementation and are generally applicable to the residential care setting, where the study will be conducted. Moreover the proposed approach would be low in cost and does not depend on other health system input. Potentially large numbers of people would benefit from the better understanding of simple methods of securing improved vitamin D status.Read moreRead less
