Review Meta AnalysisAntioxidant supplements for prevention of mortality in healthy participants and patients with various diseases.
Animal and physiological research as well as observational studies suggest that antioxidant supplements may improve survival. ⋯ We found no evidence to support antioxidant supplements for primary or secondary prevention. Vitamin A, beta-carotene, and vitamin E may increase mortality. Future randomised trials could evaluate the potential effects of vitamin C and selenium for primary and secondary prevention. Such trials should be closely monitored for potential harmful effects. Antioxidant supplements need to be considered medicinal products and should undergo sufficient evaluation before marketing.

Case Reports Comparative Study
Regional differences in mortality in Greece (1984-2004): the case of Thrace.
Mortality differences at national level can generate hypothesis on possible causal association that could be further investigated. The aim of the present study was to identify regions with high mortality rates in Greece. ⋯ Thrace is the region with the highest mortality rate in Greece. Further research is needed to assess the contribution of each possible risk factor to the increased mortality rate of Thrace which could have important public health implications.

To identify predictive factors for 2-year mortality in frail elderly patients after acute hospitalisation, and from these to derive and validate a Mortality Risk Index (MRI). A prospective cohort of elderly patients was set up in nine teaching hospitals. This cohort was randomly split up into a derivation cohort (DC) of 870 subjects and a validation cohort (VC) of 436 subjects. ⋯ The area under the ROC curve for overall score was statistically the same in the DC (0.72) as in the VC (0.71). The proposed MRI appears as a simple and easy-to-use tool developed from relevant geriatric variables. Its accuracy is good and the validation procedure gives a good stability of results.

The population of the UK is growing at the fastest rate since the 1960s, increasing on average by 0.5 per cent each year. The fastest growing age group is those aged 85 years and older, who now represent just over 2 per cent of the population, compared to just over 1 per cent in 1982. In 2007, continued increase in the population over state pension age meant for the first time this sub-group of the population exceeded the number aged under 16. ⋯ This is the second in a series of annual reports on the population of the UK, providing an overview of the latest statistics on the population, and focussing on a specific theme. This year's theme is the ageing population, with different topics to be covered in future years. The report highlights the work being taken forward as part of the National Statistics Centre for Demography (NSCD) work programme to understand the social and demographic impacts of an ageing society.
