background: hypocalcemia is a well-recognized complication after total thyroidectomy. hypovitaminosis d may have additional effect in the development of hypocalcemia. this study aimed to determine the effect of total thyroidectomy on postoperative serum calcium in patients with and without hypovitaminosis d. methods: this prospective study was performed on patients who underwent total thyroidec...

BACKGROUND Hypovitaminosis D, a condition that is highly prevalent in older adults aged 65 years and above, is associated with brain changes and dementia. Given the rapidly accumulating and complex contribution of the literature in the field of vitamin D and cognition, clear guidance is needed for researchers and clinicians. METHODS International experts met at an invitational summit on 'Vita...

There have been methodological problems for studying hypovitaminosis D and K in the elderly. First, studies were done either by evaluating food intake or measuring their circulating levels, but rarely by both in Japan. In this paper, vitamin D and K intakes and their circulating levels were simultaneously determined. Second issue is whether hypovitaminosis D and K are independent of general mal...

BACKGROUND The aim of this study is to evaluate vitamin D levels in children with latent and active TB compared to healthy controls of the same age and ethnical background. METHODS A multicenter observational study has been conducted in three tertiary care paediatric centres: Anna Meyer Children's University Hospital, Florence, Italy; Evelina London Children's Hospital, London, United Kingdom...

While it is true that many traditional cardiovascular risk factors are amenable to intervention in chronic kidney disease (CKD), the results of intervention may not be as efficacious as those obtained in the general population. Thus, there may also be a unique milieu established in CKD, which causes excess cardiovascular disease (CVD) burden by mechanisms that are as yet not fully recognized. R...

The role of hypovitaminosis D as a possible risk factor for multiple sclerosis is reviewed. First, it is emphasized that hypovitaminosis D could be only one of the risk factors for multiple sclerosis and that numerous other environmental and genetic risk factors appear to interact and combine to trigger the disease. Secondly, the classical physiological notions about vitamin D have recently bee...

Vitamin D plays a pivotal role in calcium metabolism and bone mineralization. Sufficient vitamin levels are important for the health functionality of musculoskeletal system. Hypovitaminosis is phenomenon affecting orthopedic patients worldwide. This study researched whether most two different cities countries had hypovitaminosis D, there was correlation between sunshine hours serum levels, alon...

BACKGROUND Hypovitaminosis D has been frequently reported after renal transplantation, but the impact of obesity and other factors in the reduction of vitamin D levels is not well established. We aimed to evaluate risk factors contributing to hypovitaminosis D among nondiabetic renal transplant recipients (RTR) with serum creatinine <2.0 mg/dL, at least 6 months after transplantation. METHODS...
