Received: October 17, 2018; Published: November 22, 2018 Abstract since the pathogenesis of several chronic diseases have been attributed to low concentrations of this vitamin. The present study Vitamin B12 and Vitamin D insufficiency has been observed worldwide at all stages of life. It is a major public health problem, throws light on the causal association of Vitamin B12 to cardiovascular disorders. Several evidences suggested that vitamin D has an effect in cardiovascular diseases thereby reducing the risk. It may happen in case of gene regulation and gene expression the vitamin D receptors in various cells helps in regulation of blood pressure (through renin-angiotensin system), and henceforth modulating the cell growth and proliferation which includes vascular smooth muscle cells and cardiomyocytes functioning. The present review article is based on identifying correct mechanisms and relationships between Vitamin D and such diseases that could be important in future understanding in patient and healthcare policies. There is some reported literature about the causative association between disease (CAD). Numerous retrospective and prospective studies have revealed a consistent, independent relationship of mild hyper- Vitamin B12 deficiency and homocysteinemia, or its role in the development of atherosclerosis and other groups of Coronary artery homocysteinemia with cardiovascular disease and all-cause mortality. -

Chronic administration of high doses of oral L-Carnitine in patients with severely compromised renal function or in ESRD patients on dialysis may result in accumulation of the potentially toxic metabolites, trimethylamine (TMA) and trimethylamine-N-oxide (TMAO), since these metabolites are normally excreted in the urine. Mecobalamin Should be given with caution in patients suffering from folate deficiency. The following warnings and precautions suggested with parent form – vitamin B12 The treatment of vitamin B12 deficiency can unmask the symptoms of polycythemia vera. Megaloblastic anemia is sometimes corrected by treatment with vitamin B12. But this can have very serious side effects. Don’t attempt vitamin B12 therapy without close supervision by healthcare provider. Do not take vitamin B12 if Leber’s disease, a hereditary eye disease. -
Guidelines on Food Fortification with Micronutrients
GUIDELINES ON FOOD FORTIFICATION FORTIFICATION FOOD ON GUIDELINES Interest in micronutrient malnutrition has increased greatly over the last few MICRONUTRIENTS WITH years. One of the main reasons is the realization that micronutrient malnutrition contributes substantially to the global burden of disease. Furthermore, although micronutrient malnutrition is more frequent and severe in the developing world and among disadvantaged populations, it also represents a public health problem in some industrialized countries. Measures to correct micronutrient deficiencies aim at ensuring consumption of a balanced diet that is adequate in every nutrient. Unfortunately, this is far from being achieved everywhere since it requires universal access to adequate food and appropriate dietary habits. Food fortification has the dual advantage of being able to deliver nutrients to large segments of the population without requiring radical changes in food consumption patterns. Drawing on several recent high quality publications and programme experience on the subject, information on food fortification has been critically analysed and then translated into scientifically sound guidelines for application in the field. The main purpose of these guidelines is to assist countries in the design and implementation of appropriate food fortification programmes. They are intended to be a resource for governments and agencies that are currently implementing or considering food fortification, and a source of information for scientists, technologists and the food industry. The guidelines are written from a nutrition and public health perspective, to provide practical guidance on how food fortification should be implemented, monitored and evaluated. They are primarily intended for nutrition-related public health programme managers, but should also be useful to all those working to control micronutrient malnutrition, including the food industry. -
Effects of Vitamin D Deficiency on the Improvement of Metabolic Disorders
www.nature.com/scientificreports OPEN Efects of vitamin D defciency on the improvement of metabolic disorders in obese mice after vertical sleeve gastrectomy Jie Zhang1,2,7, Min Feng3,7, Lisha Pan4,7, Feng Wang1,3, Pengfei Wu4, Yang You4, Meiyun Hua4, Tianci Zhang4, Zheng Wang5, Liang Zong6*, Yuanping Han4* & Wenxian Guan1,3* Vertical sleeve gastrectomy (VSG) is one of the most commonly performed clinical bariatric surgeries for the remission of obesity and diabetes. Its efects include weight loss, improved insulin resistance, and the improvement of hepatic steatosis. Epidemiologic studies demonstrated that vitamin D defciency (VDD) is associated with many diseases, including obesity. To explore the role of vitamin D in metabolic disorders for patients with obesity after VSG. We established a murine model of diet- induced obesity + VDD, and we performed VSGs to investigate VDD’s efects on the improvement of metabolic disorders present in post-VSG obese mice. We observed that in HFD mice, the concentration of VitD3 is four fold of HFD + VDD one. In the post-VSG obese mice, VDD attenuated the improvements of hepatic steatosis, insulin resistance, intestinal infammation and permeability, the maintenance of weight loss, the reduction of fat loss, and the restoration of intestinal fora that were weakened. Our results suggest that in post-VSG obese mice, maintaining a normal level of vitamin D plays an important role in maintaining the improvement of metabolic disorders. Obesity and its related comorbidities afect 2.1 billion people worldwide1. In last decade, bariatric surgery has emerged as an efective treatment for obese individuals because of its sustained ability to reduce body weight 2–4. -

ABSTRACT Introduction: Melatonin is generated as a product of normal circadian rhythm and is also is thought to play an important role in maintaining bone mineral density (BMD) by reducing chronic inflammation. Postmenopausal women are at an elevated risk of BMD loss due to declining estrogen and a natural decrease in melatonin synthesis with increasing age. Endogenous melatonin production is largely influenced by exposure to external light cues, but recent research has indicated that serum melatonin may be increased by the consumption of melatonin-rich foods. The purpose of this study was to quantify dietary-derived melatonin and examine its effects on inflammation, BMD, and sleep in a sample of postmenopausal women. Methods: Cross-sectional analysis of data from the National Health and Nutrition Examination Survey (NHANES) was conducted to examine differences in melatonin consumption, BMD, and sleep in postmenopausal women with chronic and low-level inflammation indicated by level of C-reactive protein (CRP). Data from the years 2005-2010 was included in this study. -

VITAMIN DEFICIENCIES in RELATION to the EYE* by MEKKI EL SHEIKH Sudan VITAMINS Are Essential Constituents Present in Minute Amounts in Natural Foods
Br J Ophthalmol: first published as 10.1136/bjo.44.7.406 on 1 July 1960. Downloaded from Brit. J. Ophthal. (1960) 44, 406. VITAMIN DEFICIENCIES IN RELATION TO THE EYE* BY MEKKI EL SHEIKH Sudan VITAMINS are essential constituents present in minute amounts in natural foods. If these constituents are removed or deficient such foods are unable to support nutrition and symptoms of deficiency or actual disease develop. Although vitamins are unconnected with energy and protein supplies, yet they are necessary for complete normal metabolism. They are, however, not invariably present in the diet under all circumstances. Childhood and periods of growth, heavy work, childbirth, and lactation all demand the supply of more vitamins, and under these conditions signs of deficiency may be present, although the average intake is not altered. The criteria for the fairly accurate diagnosis of vitamin deficiencies are evidence of deficiency, presence of signs and symptoms, and improvement on supplying the deficient vitamin. It is easy to discover signs and symptoms of vitamin deficiencies, but it is not easy to tell that this or that vitamin is actually deficient in the diet of a certain individual, unless one is able to assess the exact daily intake of food, a process which is neither simple nor practical. Another way of approach is the assessment of the vitamin content in the blood or the measurement of the course of dark adaptation which demon- strates a real deficiency of vitamin A (Adler, 1953). Both tests entail more or less tedious laboratory work which is not easy in a provincial hospital. -

A more sensitive method of screening for vitamin B12 defi- vided on page 993. ciency is measurement of serum methylmalonic acid and homocysteine levels, which are increased early in vitamin B12 deficiency. Use of the Schilling test for detection of pernicious anemia has been supplanted for the most part by serologic testing for pari- etal cell and intrinsic factor antibodies. Contrary to prevailing medical practice, studies show that supplementation with oral vitamin B12 is a safe and effective treatment for the B12 deficiency state. Even when intrinsic factor is not present to aid in the absorp- tion of vitamin B12 (pernicious anemia) or in other diseases that affect the usual absorption sites in the terminal ileum, oral therapy remains effective.

It is a fat-soluble vitamin present in many foods. It can be endogenously produced by ultraviolet rays from sunlight when the skin is exposed to initiate vitamin D synthesis. However, since vitamin D is biologically inert when obtained from sun exposure or diet, it must first be activated in human beings before functioning. The kidney and the liver play here a crucial role by hydroxylation of vitamin D to 25-hydroxyvitamin D in the liver and to 1,25-dihydroxyvitamin D in the kidney. In the past decades, it has been proven that vitamin D deficiency is involved in many diseases. Due to vitamin D’s central role in the musculoskeletal system and consequently the strong negative impact on bone health in cases of vitamin D deficiency, our aim was to underline its importance in bone physiology by summarizing recent findings on the correlation of vitamin D status and rickets, osteomalacia, osteopenia, primary and secondary osteoporosis as well as sarcopenia and musculoskeletal pain. -
