Filter by: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.
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.
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.
