BACKGROUND: The third-generation bio-intact parathyroid hormone (PTH) (1-84) assay was designed to overcome problems associated with the detection of C-terminal fragments by the second-generation intact PTH assay. The two assays have been compared primarily among dialysis populations. The present study evaluated the correlations and differences between these two PTH assays among patients with chronic kidney disease (CKD) stages 3 to 5 not yet on dialysis. METHODS: Blood samples were collected from 98 patients with CKD stages 3 to 5...

BACKGROUND: Inflammatory bowel disease (IBD) has been associated with increased risk of osteopenia and osteoporosis. Several risk factors contribute to this; however, studies evaluating their association have conflicting results. METHODS: We conducted a cross-sectional study with prospective enrollment of adult ulcerative colitis patients attending the Gastroenterology Department of Sawai Man Singh Hospital, Jaipur Rajasthan between June 2015 and December 2015. Demographic data including age, gender, body mass index (BMI), disease duration, type of disease, prior steroid use and vitamin D levels were recorded and compared with bone mineral density (BMD) using dual-energy X-ray absorptiometry (DEXA)...

Atherosclerosis is a pathological process underpinning many cardiovascular diseases; it is the main cause of global mortality. Atherosclerosis is characterized by an invasion of inflammatory cells, accumulation of lipids and the formation of fatty streaks (plaques) which subsequently allow accumulation of calcium and other minerals leading to a disturbance in the vascular endothelium and its regulatory role in arterial function. Vascular calcification is a different process, stringently regulated mainly by local factors, in which osteoblast-like cells accumulate in the muscular layer of arteries ultimately taking on the physiological appearance of bone...

The use of vitamins and minerals to prevent cancer as well as their supportive use in oncological patients is widespread and often occurs without the knowledge of the treating physician. Beyond general recommendations with regard to a balanced and healthy diet, no evidence exists supporting the use of vitamins and minerals in the prevention of cancer. Furthermore, the diet of oncological patients should contain vitamins and minerals of the same quantity as for healthy individuals. In particular, there is currently no rationale for a high-dosage administration of antioxidants...

Diabetes mellitus is known to adversely affect the bones and be associated with increased fracture risk. We examined whether eldecalcitol (ELD), an active vitamin D3 derivative, could inhibit the diabetic bone loss in streptozotocin-induced type I diabetic rats. ELD (10, 20, or 40 ng/kg), alfacalcidol (ALF; 25, 50, or 100 ng/kg), or vehicle was administered 5 times per week for 12 weeks from 1 week after diabetes induction. Normal control rats received the vehicle. Bone turnover markers, bone mineral density (BMD), and biomechanical strength of the lumbar spine and femur were measured, and bone histomorphometry was performed...

Low bone mineral density (BMD) is increasingly recognized as a common comorbid condition in ankylosing spondylitis (AS). As low BMD increases fracture risk, it is important to identify and treat low BMD in patients with AS who have been shown to be at increased risk for fractures above the population normal. Since low BMD occurs early in disease, we screen during the first year of diagnosis with dual energy x-ray absorptiometry (DXA). If patients are found to have osteoporosis by T-score of less than -2.5 or if their Z-score on DXA is more than two standard deviations below the mean, we initiate therapy with bisphosphonates in males and in females who are not planning any future pregnancies...

Micronutrient deficiencies contribute to many age-related disorders. One group at particular risk of micronutrient deficiencies is the elderly. Many elderly, such as the frail and those living in institutions, rely on ready meals of variable, often poor, nutritional quality for a significant part of their daily nutritional needs. New policies are needed to ensure that micronutrients (vitamins and minerals) and phytochemicals of known nutritional value are retained during the manufacture of ready meals. This together with increased awareness of the importance of micronutrients for health, and simple, clear labelling of the micronutrient content of ready meals would help in the choice of healthier products...

Background: Chronic kidney disease-mineral and bone disorder (CKD-MBD) has been implicated in vascular calcification pathogenesis. CKD-MBD results in alterations in the number and function of circulating endothelial progenitor cells (EPCs), physiological regulators of angiogenesis and vessel repair, commonly defined as proangiogenic progenitor cells (PACs) by the antigen pattern CD34+CD133+KDR+CD45- and putative EPCs by the pattern CD34+CD133-KDR+CD45-. These cells might acquire a calcifying phenotype in CKD-MBD, expressing mineralization biomarkers...
