    Differences in vitamin D status between countries in young adults and the elderly. McKenna MJ. Am J Med. 1992 Jul;93(1):69-77. PMID: 1385673 PURPOSE: To compare vitamin D status between countries in young adults and in the elderly. MATERIALS AND METHODS: Reports on vitamin D status (as assessed by serum 25-hydroxyvitamin D) from 1971 to 1990 were reviewed. Studies were grouped according to geographic regions: North America (including Canada and the United States); Scandinavia (including Denmark, Finland, Norway, and Sweden); and Central and Western Europe (including Belgium, France, Germany, Ireland, The Netherlands, Switzerland, and the United Kingdom). RESULTS: Vitamin D status varies with the season in young adults and in the elderly, and is lower during the winter in Europe than in both North America and Scandinavia. Oral vitamin D intake is lower in Europe than in both North America and Scandinavia. Hypovitaminosis D and related abnormalities in bone chemistry are most common in elderly residents in Europe but are reported in all elderly populations. CONCLUSIONS: The vitamin D status in young adults and the elderly varies widely with the country of residence. Adequate exposure to summer sunlight is the essential means to ample supply, but oral intake augmented by both fortification and supplementation is necessary to maintain baseline stores. All countries should adopt a fortification policy. It seems likely that the elderly would benefit additionally from a daily supplement of 10 micrograms of vitamin D.

Small breakthroughs offer big hope of AIDS 'cure' - 0 views

  •  
    Small but significant breakthrough studies on people who have been able to overcome or control HIV were presented at a major world conference on ways to stem the three-decade-old disease. One study focused on a group of 12 patients in France who began treatment on antiretroviral drugs within 10 weeks of becoming infected with human immunodeficiency virus, but then stopped the therapy after nearly three years.

    Healthy elderly French women living at home have secondary hyperparathyroidism and high bone turnover in winter. EPIDOS Study Group. Chapuy MC, Schott AM, Garnero P, Hans D, Delmas PD, Meunier PJ. J Clin Endocrinol Metab. 1996 Mar;81(3):1129-33. PMID: 8772587 These results show that vitamin D status of a French aged population in good health and living at home depends mainly on lifestyle. Like institutionalized women, old women living at home exhibit clear evidence of senile hyperparathyroidism in the winter, secondary in part to a reduced 25OHD level and associated with biological signs of increased bone turnover. The maintenance of PTH within the normal range for healthy adults by vitamin D and calcium treatment might constitute an approach for the prevention of bone loss in the entire
