Vitamin and Mineral Supplements Have a Nutritionally Significant Impact on Micronutrient Intakes of Older Adults Attending Senior Centers

Older adults frequently report use of vitamin and mineral (VM) supplements, although the impact of supplements on dietary adequacy remains largely unknown. The purpose of the current study was to evaluate micronutrient intakes of older adults with emphasis on identifying nutrients most improved by VM supplements, nutrients most likely to remain inadequate, and nutrients most likely consumed in excess. Community-based volunteers were recruited from senior centers and completed a questionnaire querying demographic data, current health status, and VM supplement use. Participants (n = 263) were then contacted by telephone to complete two 24-hour diet recalls and confirm VM supplement use. Dietary adequacy was determined by comparing the ratio of mean dietary intake to the Dietary Reference Intakes (DRI). Dietary consumption was lowest for vitamins D and E, calcium, and magnesium. VM supplementation most improved intakes of vitamins E, D, B₆, folic acid, and calcium. Participants were most likely to exceed the Tolerable Upper Limit with supplementation of niacin, folic acid, and vitamin A.     

Carrier testing and prenatal diagnosis of haemophilia — utilisation and psychological consequences

Summary. Attitudes towards prenatal diagnosis, and abortion vary widely between different countries, religions, cultures and over time. Carrier testing and prenatal diagnosis (PD) of haemophilia have become an integrated part of the comprehensive care for haemophilia in Sweden as well as in many other countries. Almost all carriers are interested in carrier testing if they are aware of the possibility. With the development of PD by chorionic villus sampling in the first trimester, the method became acceptable for many carriers, and it has in Sweden actually had an effect on the incidence of haemophilia in the 1990s. The use of PD is more common among women who perceive haemophilia as a very serious disease and who have a positive attitude towards legal abortion. The main reason for carriers not to use PD was that they do not find haemophilia to be a sufficiently serious disorder to justify an abortion. Women and their spouses are under a great deal of psychological pressure in association with the PD procedure, and the psychological consequences of having to terminate a pregnancy are long-lasting. At follow-up, about 6 years after PD and abortion, these women, however, do not have more signs of psychological distress than women without PD experience. Nevertheless, they must be offered qualified assistance both before and after PD as well as adequate follow-up after an abortion to help them cope with the emotional strain they are under.     

Intravenous gammaglobulin treatment of chronic idiopathic thrombocytopenic purpura

High-dose intravenous gammaglobulin (IVIgG) was given to 12 children and adults with chronic idiopathic thrombocytopenic purpura (ITP) to avoid splenectomy or because they either failed to respond to or required maintenance with high doses of steroids and/or immunosuppressives. The average platelet count increase to initial therapy was 239,500/microliters (range 23,000-790,000). A concomitant IgG Fc receptor blockade, measured by IgG-sensitized 51Cr-labeled autologous erythrocytes, was seen in 11 of 11 patients tested, both splenectomized and not splenectomized, lasting 3-4 wk. Six or more months after treatment, 2 children are in remission, 2 children and 2 adults are stable requiring no therapy with platelet counts of approximately 50,000 and 30,000, respectively, 3 children require maintenance IVIgG therapy at 2-10-wk intervals, and 1 child and 2 adults have become refractory to further IVIgG. Splenectomy was not performed in 4 children. Two adults were able to discontinue daily prednisone. The 3 patients who became unresponsive to Swiss Red Cross gamma-globulin (IgSRK) therapy did so in conjunction with a markedly elevated platelet-associated IgG and IgM. Serum IgM increased an average of 103 mg/dl after the IVIgG infusions. No significant side effects were seen.
