Abstract
Introduction Background: hypovitaminosis D has a prevalence of 50,4% in older persons. This population has grown globally in an impressive way during the last 20 years. In addition, the deficiency of vitamin D (< 30 ng/ml) could raise the risk of mortality in this population. Objectives: to know whether vitamin D levels less than 30 ng/ml have an impact on mortality for overall causes, cardiovascular causes, cancer or injuries (falls) in a follow-up period of nine years in elderly subjects. Methods: a retrospective longitudinal study with nine years period of observation; 418 elderly subjects were followed, and they were recruited in 2004 to participate in a study about vitamin D supplementation and muscle strength. Results: vitamin D levels below 30 ng/dl increase by almost three times the probability of dying (OR = 2.77, IC = 1.81-3.85), while the same level of vitamin D is associated with a double risk of dying from cardiovascular causes (OR = 1.78, CI = 1.21-2.09) in the unadjusted model. For cancer mortality and falls, no significant results were obtained. Vitamin D would not act as a protective factor against mortality. Conclusions: vitamin D levels less than 30 ng/ml could be a risk factor for general mortality.

Abstract
BACKGROUND Elderly persons are at elevated risk of vitamin D deficiency, which is involved in various health problems. However, its relation with age-related macular degeneration (AMD) is debated. OBJECTIVES We investigated factors associated with plasma 25-hydroxyvitamin D [25(OH)D] deficiency and the associations between plasma 25(OH)D concentrations and AMD in elderly subjects. METHODS Antioxydants, Lipides Essentiels, Nutrition et maladies OculaiRes (ALIENOR) is a population-based study on eye diseases performed in elderly residents of Bordeaux, France. Plasma 25(OH)D concentrations were assessed from blood samples and categorized as <25 nmol/L (deficiency), 25-49 nmol/L (insufficiency), or ≥50 nmol/L (sufficiency). AMD was classified as: no AMD, early AMD, and late AMD. Associations between baseline characteristics and plasma 25(OH)D status were examined with multinomial logistic regression analysis. Associations between AMD and plasma 25(OH)D status were estimated using generalized estimating equation logistic regressions. RESULTS Six hundred ninety-seven subjects with complete data were included. The prevalence of plasma 25(OH)D deficiency and insufficiency were 27.3% and 55.9%, respectively. In multivariate analysis, 25(OH)D deficiency was significantly associated with older age (P = 0.0007), females (P = 0.0007), absence of physical activity (P = 0.01), absence of vitamin D supplementation (P < 0.0001), higher plasma total cholesterol (P = 0.007), use of fibrates (P < 0.0001), lower alcohol consumption (P = 0.02), and season of blood sampling (P < 0.0001). After adjustment for these covariates and dietary omega-3 polyunsaturated fatty acid intake, smoking, and body mass index, no significant associations were found between early AMD and 25(OH)D insufficiency or deficiency (OR: 0.71, P = 0.12; OR: 0.73, P = 0.23, respectively) or with late AMD (OR: 1.04, P = 0.93; OR: 0.74, P = 0.59, respectively). CONCLUSION These findings underline the very high prevalence of plasma 25(OH)D deficiency in this elderly population but do not support a specific role for vitamin D in AMD.

Abstract
OBJECTIVES the possible therapeutic role of vitamin D in different kind of diseases explains the growing interest in this vitamin due to its pleiotropic effects. This short report shows preliminary results of prevalence of hypovitaminosis D in a group of patients and proposes a oral supplement therapy effective in correcting hypovitaminosis in a short time, without side effects. METHODS 243 patients (aged 26-93; 67 males) were enrolled at this study. We evaluated plasma levels of 25-hydroxyvitamin D [25(OH)D] with the following cut-off values: <10 ng/ml or <0-25 nmol/L (deficient), 10-30 ng/ml or 25-75 nmol/L 30-50 (insufficient) and > 30 ng/ml or > 50 nmol/L (normal). The first 73 patients with hypovitaminosis D received at baseline 25,000 IU (Cholecalciferol) per os twice a month (Tp.A). The next patients (Tp.B) at baseline received a loading dose of 50,000 IU once a week for 8 weeks, followed by a maintenance dose of 25,000 IU twice a month. RESULTS hypovitaminosis D is a widespread condition (i.e., 82.3%) not only in elderly (75.6% of 75 patients aged <65 yrs and 86.5% of 168 subjects aged >65 yrs). Preliminary results at 6 months show that Tp.B is more effective in correcting hypovitaminosis D (baseline 14.4 ± 5.3 ng/ml; 24 wk 43.3 ± 14.7 ng/ml; p<0.0001). CONCLUSION hypovitaminosis D is an important public health problem. We believe it is important to quickly achieve normal Vit. D plasma values in order to produce pleiotropic effects.

Abstract
Health care–associated and hospital-acquired infections are two entities associated with increased morbidity and mortality. They are highly costly and constitute a great burden to the health care system. Vitamin D deficiency (< 20 ng/ml) is prevalent and may be a key contributor to both acute and chronic ill health. Vitamin D deficiency is associated with decreased innate immunity and increased risk for infections. Vitamin D can positively influence a wide variety of microbial infections.
Herein we discuss hospital-acquired infections, such as pneumonia, bacteremias, urinary tract and surgical site infections, and the potential role vitamin D may play in ameliorating them. We also discuss how vitamin D might positively influence these infections and help contain health care costs. Pending further studies, we think it is prudent to check vitamin D status at hospital admission and to take immediate steps to address existing insufficient 25-hydroxyvitamin D levels.

Abstract
AIM Vitamin D deficiency is a global health issue associated with increased health-care costs, and could play a role in the pathogenesis and management of inflammatory bowel disease. Prior studies show a high prevalence of vitamin D deficiency in veterans with inflammatory bowel disease. We aimed to examine the outcome differences in patients with inflammatory bowel disease, comparing treatment with ergocalciferol to cholecalciferol. METHODS A retrospective review of electronic medical records of patients with inflammatory bowel disease at a Veterans Affairs Medical Facility in the Southeastern United States was carried out. Those with at least one serum 25(OH) vitamin D level were included. Initial and follow-up vitamin D values were recorded. The type of vitamin D supplementation, whether cholecalciferol or ergocalciferol, was documented. Costs in the year after measurement of vitamin D were divided into separate inpatient and outpatient categories. RESULTS Veterans (n = 108) with ulcerative colitis or Crohn's disease and an available 25(OH) vitamin D level were studied. There were differences in follow-up vitamin D levels; those who received weekly ergocalciferol had higher subsequent levels than those who received cholecalciferol, especially at a second follow up, although differences did not achieve statistical significance. However, those who received vitamin D3 were less likely to use laboratory, pharmacy, radiology and fee-based services, and had lower laboratory and pharmacy costs. CONCLUSIONS Our data suggest that cholecalciferol replacement might improve outcomes to a greater extent than ergocalciferol, and might be better in limiting health-care costs and expenses in patients with inflammatory bowel disease.
