RU-486 or mifepristone is best known as an antiprogestin and an abortifacient, but it has broad medical applicability. The drug is also a potent blocker of corticosteroid receptors, and it has shown promise in the treatment of breast cancer, inoperable meningioma, and cushing's disease. Cushing's is a model for the symptomatology of aging which may involve enhanced response to corticosteroid. RU-486 has reversed the osteoporosis, thinning of skin, muscle atrophy, obesity, adult onset diabetes, depression, hypertension, and immunosuppression associated with this disease. RU-486 may be of value in aiding cervical dilation, lactation, and the treatment of endometriosis. In addition, breast, bowel, kidney tumors, hepatomas, endometrial cancer, and fibrosarcomas can show corticosteroid dependency, suggesting that RU-486 may have clinical value against inoperable tumors. In a preliminary 1987 phase I study, in estrogen-positive, chemotherapy-refractory breast cancer patients in Montpelier, France, Ru-486 produced objective tumor regression (6 of 22) that was prolonged (3 months) in 4 patients. Clinical relief of bone pain was observed in 7 of 23 patients with a decline in carcinoembryonic antigen (CEA) tumor makers in 8 patients. Growing in vitro data also show that RU-486 can directly inhibit breast cancer cell proliferation. RU-486 has application for HIV infection, based on data that there is a serum factor in AIDS patients that enhances corticosteroid lympholysis. IN addition, the immune restorative action of RU-486 suggests that it could counteract the immunosuppression seen in aging, in cancer, or in viral or stress-related disease, which has recently focused clinical attention on its potential in the treatment of senile dementia and depression. Scientific conferences and workshops are needed to alert scientists, physicians, and the public to the potential medical benefits of this drug.

To assess the changes of calcium metabolism and osteopathy in patients with diabetes. Serum Ca, P, AKP, PTH, CT, plasma fasting blood glucose (FBG) and HbA1 as well as X-ray film of the lumbar spine were measured in 30 diabetes patients; 11 were IDDM and 19 were NIDDM as compared to controls matched for age and sex. There were no significant differences in Ca, P, and CT values in serum between the IDDM and NIDDM patients and controls, whereas the serum levels of PTH and AKP were significant increased in IDDM patients. The incidence of osteoporosis which was shown by X-ray film in NIDDM patients was higher than in those of controls. No correlation between PTH value and osteoporosis or clinical control of diabetes was observed.

The degree of diabetic osteopenia and serum vitamin D metabolite levels were measured in 14 type 1 (insulin-dependent) and 168 type 2 (non-insulin-dependent) diabetic patients. Based on six indices obtained by microdensitometry, we found the bone mass in 28.6% of type 1 and 26.2% of type 2 diabetic patients to be decreased and in 14.3% and 11.9%, respectively, the decrease was severe. Our method of analysis of bone mass has shown that diabetic osteopenia differs from typical osteoporosis in character. In addition, serum 24,25-dihydroxyvitamin D was significantly decreased both in type 1 and in type 2 diabetes (p less than 0.01), but 1,25-dihydroxyvitamin D was significantly decreased only in type 1 diabetes (p less than 0.01) compared to the controls, being lower than that in type 2 diabetes (p less than 0.05). On the other hand, 25-hydroxyvitamin D was similar to that of the controls, in both types of diabetes.

Drug treatment in patients who feel well but have an elevated risk of disease and premature death is steadily increasing. This kind of treatment is qualitatively different from the ordinary practice where patients visit a doctor because of symptoms or complaints. In recent decades, great confidence has evolved in this kind of risk intervention. Antihypertensive treatment is one example and risk intervention with drugs is also used in cases of hypercholesterolemia, type 2 diabetes and osteoporosis. The effect of this effort on public health has not been as great as expected. This kind of treatment has emerged gradually and without debating the principles. The author wants to start a debate about what kind of treatment we are experiencing. Is it quasi-treatment based on the premises of the technology? Should we think again about this kind of practice? The author suggests subjects for further debate, including the use of precise language, better co-operation with the persons at risk and further research.

Ageing constitutes a risk factor for magnesium deficit. Primary magnesium deficit originates from two aetiological mechanisms: deficiency and depletion. Primary magnesium deficiency is due to insufficient magnesium intake. Dietary amounts of magnesium are marginal in the whole population whatever the age. Nutritional deficiencies are more pronounced in institutionalized than in free-living ageing groups. Primary magnesium depletion is due to dysregulation of factors controlling magnesium status: intestinal magnesium hypoabsorption, reduced magnesium bone uptake and mobilization, sometimes urinary leakage, hyperadrenoglucocorticism by decreased adaptability to stress, insulin resistance and adrenergic hyporeceptivity. Secondary magnesium deficit in ageing largely results from various pathologies and treatments common to elderly persons, i.e., non-insulin dependent diabetes mellitus and use of hypermagnesuric diuretics. Magnesium deficit may participate in the clinical pattern of ageing, particularly in neuromuscular, cardiovascular and renal symptomatologies. The consequences of hyperadrenoglucocorticism-the simplest marker of which is non-response to the dexamethasone suppression test-may include immunosuppression, muscle atrophy, centralization of fat mass, osteoporosis, hyperglycaemia, hyperlipidaemia, atherosclerosis, and disturbances of mood and mental performance through accelerated hippocampal ageing particularly. It seems very important to point out that magnesium deficit and stress aggravate each other in a true 'pathogenic vicious circle', particularly in the stressful state of ageing. The importance of magnesium deficit in the aetiologies of insulin resistance, and the adrenergic, osseous, oncogenic, immune and oxidant disturbances of ageing is still uncertain. Oral physiological magnesium supplementation (5 mg Mg/kg/d) is the best diagnostic tool for establishing the importance of magnesium deficiency. Too few open and double blind studies on the effects of the treatment of magnesium deficiency and of magnesium depletion in geriatric populations have been done. Further study is necessary to assess the true place of magnesium deficit in the pathophysiology of ageing.

Nutrition and food science have each enhanced the development of an abundant, nutritious, safe food supply. A healthy diet should contain all of the required nutrients and sufficient calories to balance energy expenditure and provide for growth and maintenance throughout the life cycle. Importantly, dietary factors are associated with 5 of the 10 leading causes of death, including coronary heart disease, certain types of cancer, stroke, noninsulin dependent diabetes mellitus and atherosclerosis. National health care expenditures for 1990 totaled $666 billion of which 30% are related to inappropriate diet. Identification of external factors that contribute to premature death would aid preventive efforts, improve the quality of life, and reduce health care costs. Even though genetic predisposition increases susceptible people's risk for many of these chronic diseases, these conditions may be diminished or prevented by improvements in the American diet. Each stage of the life cycle has specific nutrient needs. Throughout infancy, childhood and adolescence nutrients are required to meet the growth processes as well as cognitive function. During pregnancy nutrients are required for both mother and developing infant needs. Adult nutrition focuses on tissue maintenance, nutrient and energy needs, and disease prevention. As the population of elderly increase in number and greater age, nutritional needs must be met to minimize certain disease states and assure the quality of life. Nutrition associated health risks have been identified for coronary heart disease, cancer and diabetes mellitus. Recommendations for each includes a decrease in dietary fat, awareness of caloric intake and enhancement of nutrient density including an increase in fruit and vegetables. These recommendations also impact obesity and diminish the compounding of other disease states affected by excessive body weight. Calcium intake at early ages affects development of bone density and manifestation of osteoporosis. Current gaps in knowledge are also identified that could improve health. Numerous nutrients are being examined for their regulation of specific gene expressions and in the processes of transcription and translation. To offer food products with greater nutrient density or improved functional health ingredients, modification of existing foods is needed to assure an improved diet. Policies to improve health require integration of nutrition needs with economic growth and development, agriculture and food production, processing, marketing, health care and education, and includes changing life styles and food choices. Increased research support is required to achieve national health goals with emphasis on nutrition and food sciences. Education methods must be improved to better inform consumers, to encourage food producers and manufactures to produce healthier foods, to assure training of future professionals and to provide legislators with the basis to make informed decisions. Recommendations to CFERR are identified. Improved quality and availability of nutritious foods will result in a healthier, more productive population. A decrease in the occurrence and duration of chronic disease should diminish the cost of health care and allow these resources to further benefit the nation. International concerns about undernutrition include 780 million people who are malnourished, lacking sufficient food to meet their basic nutritional needs for protein and energy, and 2 billion people who subsist on diets lacking essential nutrients needed for growth, development and physiological maintenance. National concerns about undernutrition exist based on incomplete data identified by indices of hunger and characterized by an increased demand for food assistance for women, children and the elderly. Major health problems in the US impacted by diet and nutrition include coronary heart disease, atherosclerosis, some types of cancer, non-insulin dependent diabetes mellitus, hypert

Ageing constitutes a risk factor for magnesium deficit. Primary magnesium deficit originates from two etiological mechanisms: deficiency and depletion. Primary magnesium deficiency is due to insufficient magnesium intake. Dietary amounts of magnesium are marginal in the whole population whatever the age. Nutritional deficiencies are more pronounced in institutionalized than in free-living ageing groups. Primary magnesium depletion is due to dysregulation of factors controlling magnesium status: intestinal magnesium hypoabsorption, reduced magnesium bone uptake and mobilisation, sometimes urinary leakage, hyperadrenoglucocorticism by decreased adaptability to stress, insulin-resistance and adrenergic hyporeceptivity. Secondary magnesium deficit in ageing largely results from various pathologies and treatments common to elderly persons: i.e. non insulin dependent diabetes mellitus and use of hypermagnesuric diuretics. Magnesium deficit may participate in the clinical pattern of ageing: mainly neuromuscular, cardiovascular and renal symptomatologies. The consequences of hyperadrenoglucocorticism--whose non response to dexamethasone suppression test appears the simplest marker--may concern immunosuppression, muscle atrophy, centralization of fat mass, osteoporosis, hyperglycemia, hyperlipidemia, atherosclerosis, disturbances in mood and mental performances through accelerated hippocampal ageing particularly. Treatment of magnesium deficiency requires simple oral physiological magnesium supplementation. Treatment of the different types of magnesium depletion leads to a more or less specific control of pathophysiological disturbances of the required magnesium substrate. Open and double blind studies on the effects of the treatments of magnesium deficiency and of magnesium depletions in geriatic populations are too scarce. Further study is necessary to assess the accurate place of magnesium deficit in the physiopathology of ageing.

Several conditions have been described to cause osteoporosis, including diabetes mellitus. While the relationship between type 1 diabetes and osteopenia is well documented in the literature, data on the presence of this complication in type 2 diabetes have not been well established. We studied a population composed of 66 post-menopausal women with type 2 diabetes and a control population. We examined bone mineral density with the dual-energy X-ray absorptiometry (DXA) technique at the lumbar and femoral levels and, in a subgroup of patients, we also measured the levels of markers of bone remodelling. We found significantly higher levels of bone mineral density at the femoral (but not lumbar) level in the diabetic subjects compared with the control population in all the examined subregions, except Ward's triangle. Moreover, we found higher levels of some markers of bone resorption (urinary calcium and hydroxyproline, telopeptide) in the patients with diabetes, while urinary crosslinks were higher in the controls. On the basis of these results, we suggest that osteoporosis cannot be considered a complication of type 2 diabetes and that, from a metabolic point of view, bone resorption is greater in diabetic patients than in normal subjects, as suggested by the high levels of most of the markers of osteoclastic activity.

Preventive medicine consists of all efforts which delay the development of diseases (primary prevention), make early detection possible (secondary prevention) as well as rehabilitation of patients (tertiary prevention). The aim to reduce premature morbidity and mortality and increase life expectancy and quality of life. The authors summarize the secondary preventive interventions of asymptomatic individuals namely primary screening methods, with special regard to so-called "western diseases": hypertension, hyperlipidemia, colorectal cancer, neoplasms of breast, cervix, prostata, also considering type 2 diabetes and osteoporosis on the basis of the supporting evidence and the recommendation of certain national committees.

A probiotic is a viable microbial dietary supplement that beneficially affects the host through its effects in the intestinal tract. Probiotics are widely used to prepare fermented dairy products such as yogurt or freeze-dried cultures. In the future, they may also be found in fermented vegetables and meats. Several health-related effects associated with the intake of probiotics, including alleviation of lactose intolerance and immune enhancement, have been reported in human studies. Some evidence suggests a role for probiotics in reducing the risk of rotavirus-induced diarrhea and colon cancer. Prebiotics are nondigestible food ingredients that benefit the host by selectively stimulating the growth or activity of one or a limited number of bacteria in the colon. Work with prebiotics has been limited, and only studies involving the inulin-type fructans have generated sufficient data for thorough evaluation regarding their possible use as functional food ingredients. At present, claims about reduction of disease risk are only tentative and further research is needed. Among the claims are constipation relief, suppression of diarrhea, and reduction of the risks of osteoporosis, atherosclerotic cardiovascular disease associated with dyslipidemia and insulin resistance, obesity, and possibly type 2 diabetes. The combination of probiotics and prebiotics in a synbiotic has not been studied. This combination might improve the survival of the bacteria crossing the upper part of the gastrointestinal tract, thereby enhancing their effects in the large bowel. In addition, their effects might be additive or even synergistic.
