Filter by:Randomized double blind placebo controlled trial of vitamin D supplements, with or without calcium supplementation, versus placebo in reduction of recurrences in BPPV.
Obesity is likely to be the disease of the 21th century. The growth of obesity is worldwide, a pandemic, and has increased globally in the last 30 years. Developed countries were more affected, but developing countries have increasingly contributed to this epidemic as they continue to modernize. The national and global burden of obesity, with its public health and financial implications, is projected to increase markedly in the next two decades. the study aimed to assess the effect of Vit D supplementation on preventing altered levels of calcium, Vit D, and parathormone after laparoscopic sleeve gastrectomy.
This randomised trial will investigate the effect of calcium supplementation on bone and calcium metabolism in women during acute load carriage exercise. This study will test the hypothesis that calcium supplementation before load carriage exercise will attenuate the decline in serum ionised calcium and increase in parathyroid hormone and bone resorption.
The investigators aimed to evaluate the relationship between LUTS and vitamin D with uroflowmetry parameters in female patients. They found no relation between vitamin D levels and LUTS in respect to uroflowmetry. However, in low vitamin D patients, Ca is related with urologic problems. The investigators believe that there is a need for studies emphasizing serum Ca levels in addition to vitamin D levels in patients with LUTS.
In the present study, the severity of recurrent laryngeal nerve injury (RLNI) and hypocalcemia (H) will be followed-up and the probable interrelation between them will be proposed considering the clinical situation of patients, e.g. improvement in hypocalcemia also make a positive effect on voice? (any objective sign? Ca? PTH?), return of voice is parallel with the improvement in hypocalcemia? Postoperative calcium (Ca), parathyroid hormone (PTH), regular vocal cord evaluations by ear-nose-throat (ENT) exams, deterioration-stability-improvement of clinical symptoms regarding both Ca metabolism and vocal cord function will be noted at regular intervals (postoperative day 1-3-first, weekly control/first month, monthly/first 6-month, 3-monthly/6-12 months) at outpatient controls. Serum Ca, PTH, ENT evaluation of vocal cords-noted.
The purpose of this study is to demonstrate that the intestinal absorption of calcium from a newly developed calcium carbonate-vitamin D3 chewable tablet formulation increases the amount of calcium excreted in urine and decreases parathyroid hormone (PTH) in serum as compared to baseline.
The purpose of this study is to determine whether eating Kellogg's Nutri-Grain cereal bars will increase calcium intake in healthy adult women.
This study is to determine the amount of vitamin D required for a very low birth weight infant to reach vitamin D sufficiency and achieve optimal calcium health and bone growth.
