BACKGROUND The effects of vitamin D supplementation in healthy prepubertal children on physiologic outcomes have not been investigated. OBJECTIVE The objective was to evaluate the effects of supplementation with 1000 IU vitamin D(3)/d on calcium absorption. DESIGN In a double-blind, placebo-controlled trial, we randomly assigned 64 children to 1000 IU vitamin D(3)/d (n = 32) or placebo (n =...

BACKGROUND Calcium supplementation may prevent high blood pressure through a number of mechanisms and may help to prevent preterm labour. OBJECTIVES The objective of this review was to assess the effects of calcium supplementation during pregnancy on hypertensive disorders of pregnancy and related maternal and child adverse outcomes. SEARCH STRATEGY We searched the Cochrane Pregnancy and Ch...

Rickets is typically due to nutritional cause, namely vitamin D and calcium deficiency worldwide. When there suboptimal response conventional supplementation, alternative causes have be sought. We report a rare case of D-dependent rickets (VDDR) who presented with rachitic features but normal total 25-hydroxyvitamin 25(OH)D level. Conventional inactive supplementation was ineffective high dose ...

1 Interpretative Summary: Effect of oral calcium supplementation on early lactation health 1 and milk yield in commercial dairy herds. By Oetzel and Miller, page 000. Low blood 2 calcium often occurs in older cows around calving and impairs subsequent health and milk yield. 3 Second lactation or greater cows in 2 commercial dairies with effective milk fever prevention 4 were divided into contro...

BACKGROUND Postoperative hypoparathyroidism is the most common complication after total thyroidectomy, owing to unintentional injury or decreased blood flow to the parathyroid glands. Prediction of postoperative hypoparathyroidism would be helpful for surgeons to manage postoperative hypocalcemia. In this study, we scored the discoloration of the parathyroid glands using a new parathyroid scori...

Objective This study sought to investigate the effects of vitamin D supplementation and aquatic exercise on pulmonary function in postmenopausal women. Materials and methods This prospective and controlled study included 104 women (62 ± 6.5 years) divided into three groups: a control group lacking vitamin D and calcium supplementation which remained sedentary (CG; n = 17); a control group rec...

BACKGROUND Evidence suggests that increased maternal calcium intake during pregnancy may result in lower offspring blood pressure, prompting calls for more robust data in this field, particularly in settings of habitually low calcium intake. OBJECTIVE The objective was to investigate the effect of maternal calcium supplementation on blood pressure in offspring by recruiting children born afte...

ANIMALS 12 healthy adult dogs. PROCEDURE Canned dog food was fed to dogs for ...

OBJECTIVE The aim of this study was to evaluate the use of prophylactic oral calcium after total thyroidectomy in the prevention of symptomatic hypocalcemia, and to develop a rational strategy of oral calcium supplementation following this type of surgery. SUBJECTS AND METHODS Prospective study including 47 patients undergoing total thyroidectomy from January 2007 to February 2012. The patien...
