BACKGROUND Calcifediol (25D) availability is crucial for calcitriol (1,25D) synthesis, but regulation of vitamin D hydroxylases is majorly responsible for 1,25D synthesis. The net efficiency of vitamin D hydroxylases might be informative. We assume that the ratio between calcitriol and calcifediol (25D/1,25D) serum concentrations could suggest the vitamin D hydroxylation efficiency. METHODS W...
According to new research in JAMA Internal Medicine, relatively high doses of vitamin D may increase the risk of falls. The study—designed to determine whether doses of vitamin D that achieved blood concentrations of 30 ng/mL improve strength and balance—comprised 200 men and women (age 70 and older) who were living at home with reasonably good cognition and mobility, but had a prior fall. More...
BACKGROUND Epicardial adipose tissue (EAT) is recognized as a useful indicator for type 2 diabetes mellitus (T2DM) and obesity. However, studies on the association between vitamin D status and EAT thickness in type 2 diabetes (T2D) are limited. In this study, we aimed to evaluate the association of vitamin D (Calcifediol) status and EAT thickness (EATT) in Chinese non-obese patients with T2D. M...
In this study, a dispersive liquid–liquid microextraction method using an extraction solvent lighter than water has been developed for the extraction and preconcentration of cholecalciferol and calcifediol from plasma samples followed by high performance liquid chromatography determination. Initially, acetonitrile and sodium chloride (NaCl) are added into the plasma as an extraction solvent and...
Introduction Secondary hyperparathyroidism (SHPT) and vitamin D deficiency are common at kidney transplantation and are associated with some early and late complications. This study was designed to evaluate whether paricalcitol was more effective than nutritional vitamin D for controlling SHPT in de novo kidney allograft recipients. Methods This was a 6-month, investigator-initiated, multicen...
