The actual nutrition and vitamin provision in 14-17-year-old schoolchildren in Oryol and the Oryol Region were studied within the framework of the working programme. Sanitary recommendations for vitamin prophylaxis were developed. Evidence is provided for the biomedical efficiency of vitamin prophylaxis.
Crohn's disease is frequently associated with nutritional deficiencies, often a result of disease activity and poor oral intake. This study investigated the adequacy of dietary intake, based on the Canadian Dietary Reference Intake, in ambulatory patients with Crohn's disease and a normal body mass index (BMI; calculated as kg/m(2)). This was a cross-sectional study of 74 patients with mean age of 35.7+/-1.4 years and BMI of 23.05+/-0.45. All patients completed a 7-day food record and a diary for the Crohn's Disease Activity Index. Mean Crohn's Disease Activity Index was 138.99+/-11.38. Energy and protein intakes were within the recommended levels of intake, but total carbohydrates, fat, and saturated fat intake exceeded the recommended levels of
Adjuvant Nutritional Intervention in Cancer (ANICA) was a clinical study carried out in Denmark in the 1990s with 32 typical patients with breast cancer, aged 32-81 yr and classified high risk because of tumor spread to the lymph nodes. The patients received standard therapy for their breast cancer, but got from the start additionally an adjuvant therapy in form of a cocktail consisting of vitamin C (2,850 mg/day), vitamin E (2,500 IU/day), beta-carotene (32.5 IU/day), selenium (Se; 387 micrograms/day), various other vitamins and essential trace elements, essential fatty acids (1.2 g gamma-linolenic acid/day and 3.5 g omega-3 PUFAs/day), and coenzyme Q10 (CoQ10, 90 mg/day). The protocol was later changed, with reduction of the Se intake and more coenzyme Q10 than when the study was started. The average survival of high-risk breast patients in the study was 50% after 5 yr, whereas for low-risk breast cancer patients (without metastases in the axilla when treatment was started), the average survival was 90% after ten years. The main investigator died, and the final report from the ANICA study was therefore never written. However, the published preliminary results from the trial were very promising; it seems, therefore, important to follow-up this study.
Cataractous-opacification of the lens is one of the leading causes of blindness in India. The situation can be managed by surgical removal of the cataractous lens. Various pharmacological strategies have been proposed for the prevention and treatment of cataract. Information on possible benefits of putative anticataract agents comes from a variety of approaches, ranging from laboratory experiments, both in vitro and in vivo , to epidemiological studies in patients. This review deals with the various mechanisms, and possible pharmacological interventions for the prevention of cataract. The article also reviews research on potential anticataractous agents, including aldose reductase inhibitors, glutathione boosters, antiglycating agents, vitamins and various drugs from indigenous sources.
Energy expenditure, physical and mental capacity for work, ascorbic acid excretion, basic foodstuff supply were investigated in 7-9-year-old pupils from boarding schools. Specific features of the alimentary state of the children were used as a basis for working out hygienic recommendations to improve children's diets and health.
The data on of alimentary risk factors of osteoporosis have been observed. The frequency of decreased bone mineral density, vitamin and calcium diet content and sufficiency with vitamins evaluated by means of blood serum level determination among patients suffering from chronic diseases (of cardiovascular system, gastrointestinal tract, osteopenia and osteoporosis).
The aim of the study was to assess the relationships between individual-level dietary intakes of antioxidant vitamins C, E and beta-carotene with all-cause and cause-specific mortality in three Central and Eastern European (CEE) populations.
Data from the Health, Alcohol and Psychosocial factors in Eastern Europe cohort study were used. At the baseline survey, between 2002 and 2005, 28,945 men and women aged 45-69 years were examined in Novosibirsk (Russia), Krakow (Poland) and seven Czech towns. Deaths in the cohorts were identified through mortality registers. Cox regression was used to estimate the association between vitamin consumption and all-cause, cardiovascular (CVD) disease and cancer mortality.
In multivariable-adjusted analyses, there were no clear inverse associations between antioxidant vitamin intakes and mortality, although in some groups, several hazard ratios (HRs) were significant. For example, in men, compared with the lowest quintile of vitamin C intake, all-cause mortality in the third and fourth quintiles was lower by 28 % (HR 0.72; 95 % CI 0.61-0.85) and by 20 % (HR 0.80; 95 % CI 0.68-0.95), respectively. CVD mortality was lower by 35 % (HR 0.65; 95 % CI 0.50-0.84) and by 23 % (HR 0.77; 95 % CI 0.59-0.99) in third and fourth quintile of vitamin C intake, respectively. In women, the third and fourth quintiles of dietary intake of vitamin E were associated with reduced risk of all-cause death by 33 % (HR 0.67; 95 % CI 0.53-0.84) and by 23 % (HR 0.77; 95 % CI 0.61-0.97), respectively. Consumption of vitamin C, vitamin E and beta-carotene was not related to CVD mortality in women and to cancer mortality in either gender.
This large prospective cohort study in CEE populations with low prevalence of vitamin supplementation did not find a strong, dose-response evidence for protective effects of antioxidant vitamin intake.

The timing and frequency of periconceptional multivitamin use may be related to the risk of preeclampsia. Women in the Danish National Birth Cohort (1997-2003) reported multivitamin or folate-only supplement use during a 12-week periconceptional period (from 4 weeks prior to 8 weeks after the last menstrual period). Preeclampsia cases were identified by using International Classification of Diseases, Tenth Revision, codes. Cox regression was used to estimate the association of frequency (weeks of use) and timing (preconception and postconception) of use with preeclampsia risk. Overall, there were 668 cases of preeclampsia (2.3%), and 18,551 women (65%) reported periconceptional multivitamin use. After adjustment, regular use (12 of 12 weeks) was related to a reduced risk of preeclampsia among normal-weight women. Compared with nonusers with a body mass index of 22 kg/m(2), regular multivitamin users with the same body mass index had a 20% reduced risk of preeclampisa (hazard ratio = 0.78, 95% confidence interval: 0.60, 0.99). In addition, regular use in the postconception period only was associated with reduced risk, a relation that also appeared to be limited to women with a body mass index of
