The proper dietary calcium intake and calcium supplementation, when indicated, are important factors in the acquisition of peak bone mass during youth and in the prevention of fractures in old age. In addition to its deposition in bone, calcium confers an increase in its resistance and exhibits important activities in different enzymatic pathways in the body (e.g., neural, hormonal, muscle-rela...

This study assessed the effect of calcium supplementation towards the change in serum calcium, phosphorus and magnesium level. We carried out a randomized controlled trial of calcium supplementation in 113 postmenopausal women for 24 months period study. Subjects were randomly assigned into two groups. Subjects in Calcium Supplemented Group (CSG) were to take calcium supplement (1200 mg/day) wh...

Long-term vitamin D and calcium supplementation is effective in reducing nonvertebral fractures in elderly people. Increased bone fragility caused by secondary hyperparathyroidism (sHPT) and impaired balance are known risk factors for hip fractures. The hypothesis is that short-term therapy with calcium and vitamin D may improve body sway as well as sHPT more effectively than calcium monotherap...

An oral calcium bolus (Bovikalc, Boehringer Ingelheim Vetmedica) supplying calcium to dairy cows in the form of calcium chloride and calcium sulfate was evaluated to determine the effect on calcium homeostasis immediately after calving. Cows in the treatment group received one bolus immediately after calving and a second bolus 12 hours later. Control cows received no calcium supplementation. Bl...

BACKGROUND Calcium supplementation has been proposed after bilateral thyroid surgery, either to all patients or to those with biochemical hypocalcaemia. It has also been suggested that supplementation aids parathyroid recovery and prevents permanent hypoparathyroidism. This single-centre study investigated the feasibility of a restrictive management of post-thyroidectomy hypocalcaemia. METHOD...

OBJECTIVE To determine if the intraoperative rapid parathyroid hormone (PTH) assay can be used to accurately predict postoperative calcium levels following total or completion thyroidectomy. DESIGN A prospective study. SETTING Tertiary care referral center. PATIENTS One hundred four patients following a total or completion thyroidectomy.Intervention Intraoperative rapid plasma PTH levels ...

An increasing prevalence of calcium and/or vitamin D deficiency in the general population (especially, but not only, in elderly subjects) has been emphasized in recent epidemiologic studies. These deficiencies could be responsible for accelerated bone loss mediated by secondary hyperpara-thyroidism and increased bone turnover and could explain the dramatic increase of the incidence of osteoporo...

BACKGROUND It is undetermined whether calcium supplementation has an effect on obesity or body composition in postmenopausal women. The purpose of the study is to detect the effect of calcium supplementation on indices of obesity and body composition. METHODS This is a secondary analysis of data from a population-based, double-blind, placebo-controlled, randomized trial designed to determine ...
