A 3 months randomized, placebo-controlled study on the effect of toothpaste fortified with vitamin B12 on vitamin B12 status markers and related metabolic markers. The primary outcome vari...
This study was designed to determine whether elderly residents of long term care facilitated who had been taking proton pump inhibitors (PPI) for more than 12 months were more likely to ha...
There is a high prevalence of vitamin D deficiency in Switzerland. In indoor-athletes as well as wheelchair users, vitamin D deficiency occurs even more often. It is well established that ...
In the present study the design of the vitamin B12 absorption test, CobaSorb, is further optimised. We investigate which test – measurement of holotranscobalamin or cobalamins – could ...
Breastfed infants living in a northern location (41 degrees N) are at high risk of vitamin D deficiency during winter. This trial is designed to determine how much supplemental vitamin D b...
Treatment of vitamin D deficiency in adults requires adequate diagnosis based on the rigorous definition of the disease. Recently, it has been reported that assessment criteria for vitamin D deficienc...
Vitamin D is well known for its role in bone health and immune regulation, playing a role in cell differentiation, proliferation, and apoptosis. Vitamin D deficiency also has been associated with vari...
Vitamin D deficiency rickets is characterized by mineralization impairment in bone and cartilage of children caused by vitamin D deficiency in the body due to limited sunlight exposure and vitamin D i...
Elderly people living in long term care institutions are particularly at risk of vitamin B deficiency. The prevalence of vitamin B deficiency was 34.9% among the 1996 institutionalized elderly residen...
The risk of vitamin D deficiency varies with the season. The frequency of vitamin D deficiency in migraine patients and its association with migraine are unclear.
A glycoprotein secreted by the cells of the GASTRIC GLANDS that is required for the absorption of VITAMIN B 12 (cyanocobalamin). Deficiency of intrinsic factor leads to VITAMIN B 12 DEFICIENCY and ANEMIA, PERNICIOUS.
A nutritional condition produced by a deficiency of VITAMIN E in the diet, characterized by posterior column and spinocerebellar tract abnormalities, areflexia, ophthalmoplegia, and disturbances of gait, proprioception, and vibration. In premature infants vitamin E deficiency is associated with hemolytic anemia, thrombocytosis, edema, intraventricular hemorrhage, and increasing risk of retrolental fibroplasia and bronchopulmonary dysplasia. An apparent inborn error of vitamin E metabolism, named familial isolated vitamin E deficiency, has recently been identified. (Cecil Textbook of Medicine, 19th ed, p1181)
A nutritional condition produced by a deficiency of VITAMIN D in the diet, insufficient production of vitamin D in the skin, inadequate absorption of vitamin D from the diet, or abnormal conversion of vitamin D to its bioactive metabolites. It is manifested clinically as RICKETS in children and OSTEOMALACIA in adults. (From Cecil Textbook of Medicine, 19th ed, p1406)
A nutritional condition produced by a deficiency of VITAMIN A in the diet, characterized by NIGHT BLINDNESS and other ocular manifestations such as dryness of the conjunctiva and later of the cornea (XEROPHTHALMIA). Vitamin A deficiency is a very common problem worldwide, particularly in developing countries as a consequence of famine or shortages of vitamin A-rich foods. In the United States it is found among the urban poor, the elderly, alcoholics, and patients with malabsorption. (From Cecil Textbook of Medicine, 19th ed, p1179)
A nutritional condition produced by a deficiency of VITAMIN B 12 in the diet, characterized by megaloblastic anemia. Since vitamin B 12 is not present in plants, humans have obtained their supply from animal products, from multivitamin supplements in the form of pills, and as additives to food preparations. A wide variety of neuropsychiatric abnormalities is also seen in vitamin B 12 deficiency and appears to be due to an undefined defect involving myelin synthesis.
