Although vitamins play a major role in health, and their deficiency may be linked to symptoms of optic-nerve dysfunction, the association between serum vitamin levels and glaucoma in humans remains controversial. In this study, articles in the PubMed, Web of Science, and EMBASE databases were searched up to 25March 2017. Nine studies on primary open-angle glaucoma (POAG), four studies on normal tension glaucoma (NTG), and six studies on exfoliative glaucoma (EXG) were retrieved. The combined results showed no differences in the levels of serum vitamin B₆ between POAG (p = 0...

BACKGROUND: Vitamin D is recognised to have multiple actions, including role in immune modulation. The prevalence and impact of vitamin D deficiency (VDD) in abdominal tuberculosis is unknown. METHODS: We report the prevalence and clinical impact of VDD in patients with abdominal tuberculosis. The patients were divided into two groups: VDD (<20 ng/ml) or vitamin D sufficient (VDS) (⩾20 ng/ml). Groups were compared for extent (abdominal alone or extra-abdominal also) of disease and pattern of involvement (intestinal, peritoneal or both) and inflammatory response [serum C-reactive protein (CRP)]...

Vitamin deficiencies are major forms of micronutrient deficiencies, and are associated with huge economic losses as well as severe physical and intellectual damages to humans. Much evidence has demonstrated that biofortification plays an important role in combating vitamin deficiencies due to its economical and effective delivery of nutrients to populations in need. Biofortification enables food plants to be enriched with vitamins through conventional breeding and/or biotechnology. Here, we focus on the progress in the manipulation of the vitamin metabolism, an essential part of biofortification, by the genetic modification or by the marker-assisted selection to understand mechanisms underlying metabolic improvement in food plants...

BACKGROUND: Crohn's disease (CD) frequently manifests in the second and third decades of life. Malnutrition and corticosteroid therapy may affect bone mineralization and delay bone growth. Our aim was to study bone mineral density and factors associated low bone mineral density (BMD) in pediatric CD. METHODS: A cross-sectional observational study in children with CD (aged 5 to <18 years) was done. Demographic and treatment details were noted. Vitamin D levels <20 ng/mL were considered as deficiency...

OBJECTIVE: To characterise German vitamin and mineral supplement users differentiated by their motives for supplement use. DESIGN: Data were obtained from the German National Nutrition Monitoring (2010/11) via two 24 h dietary recalls and a telephone interview. Motive-based subgroups of supplement users were identified by factor and cluster analysis. Sociodemographic, lifestyle, health and dietary characteristics and supplement use were examined. Differences were analysed using χ 2 tests, logistic and linear regression models...

It was with great interest I read the recent contribution by Christie-David and Gunton, 'Vitamin C deficiency and diabetes mellitus - easily missed?' [1], outlining their retrospective cohort study in 11 patients with poorly healing foot ulcers in the setting of diabetes mellitus. Their findings suggest previously unrecognized vitamin C deficiency may have been a contributing factor to the ulcers that were being treated in their clinic; a hypothesis supported by the healing reported to occur within 3 weeks of the commencement of vitamin C replacement [1]...

REVIEW
Angelo Azzi
Four tocopherols are available in nature and are absorbed with the diet, but only one RRR-α-tocopherol satisfies the criteria of being a vitamin. The biological activity of the different tocopherols studied in the rat by the resorption-gestation test has been inconsistently extrapolated to human beings where the tocopherols have no influence on a successful pregnancy. Diminution of RRR-α-tocopherol intake results in diseases characterized by ataxia, whose pathogenetic mechanism, despite vigorous claims, has not been clarified...

Introduction Vitamin D deficiency is associated with various diseases. Prevalent in Brazil, it can result from inadequate lifestyle habits. Objective To demonstrate that postmenopausal women with vitamin D deficiency have worse quality of health, expressed as worse quality of life, lower levels of physical activity, and worse nutritional profile. Methods Postmenopausal women answered questionnaires about physical activity and quality of life, provided a 24-hour food record, and had serum vitamin D levels measured...

Considering the well-known antioxidant properties of statins, it seems important to assess their impact on major markers of oxidative stress (superoxide anion radical, nitric oxide, and index of lipid peroxidation) to compare the antioxidative potentials of atorvastatin and simvastatin during the different degrees of hyperhomocysteinemia (HHcy) in rats. This study was conducted on adult male Wistar albino rats (n = 90; 4 weeks old; 100 ± 15 g body mass) in which HHcy was achieved by dietary manipulation...

Richard Hoffman
Micronutrient deficiencies contribute to many age-related disorders. One group at particular risk of micronutrient deficiencies is the elderly. Many elderly, such as the frail and those living in institutions, rely on ready meals of variable, often poor, nutritional quality for a significant part of their daily nutritional needs. New policies are needed to ensure that micronutrients (vitamins and minerals) and phytochemicals of known nutritional value are retained during the manufacture of ready meals. This together with increased awareness of the importance of micronutrients for health, and simple, clear labelling of the micronutrient content of ready meals would help in the choice of healthier products...
