This randomised placebo-controlled trial aimed to determine the effect of 16-weeks cholecalciferol supplementation on calcium-phosphate homeostasis and bone mineral density (BMD) in overweight and obese adults. Fifty-four vitamin D-deficient (25OHD<50 nmol/L), overweight and obese adults (mean age
Plasma FGF-23 concentrations and its relationship with calcium-phosphate homeostasis were evaluated in 48 perimenopausal obese women and in 29 nonobese controls. Serum parathyroid hormone, 25-hydroxyvitamin D(3), CTX1, osteocalcin, total calcium, phosphorus, creatinine, and plasma intact FGF-23
OBJECTIVE
To evaluate, during the first postoperative year in obese pre-menopausal women, the effects of laparoscopic gastric banding on calcium and vitamin D metabolism, the potential modifications of bone mineral content and bone mineral density, and the risk of development of secondary
Jejuno-ileostomy was performed in eight women because of severe alimentary obesity. Their calcium phosphate and bone metabolism was studied an average of 31 months post-operatively. This revealed secondary intestinal hyperparathyroidism due to an artificial malabsorption syndrome. While most of the
Immunoassay interference is most often found for Prolactin measurement. Only few data exist on immunoassay interference for other hormones.A 36 years old obese female subject (BMI 31 kg/m2) regularly attended our endocrine unit for type 2 diabetes therapy. BACKGROUND
Observational studies in obese adults have found abnormal urinary metabolic indices that predispose to nephrolithiasis. Few studies have been performed in severely obese adolescents.
OBJECTIVE
To assess urinary stone risk factors in severely obese adolescents and in those undergoing 2
The prevalence and incidence of urinary stone disease have been reported to be associated with body weight and body mass index (BMI). The aim of the study was to determine the difference in stone components among different BMI groups in patients with urolithiasis. Between Dec 2005 and Jan 2008, 907
JFD (N-isoleucyl-4-methyl-1,1-cyclopropyl-1-(4-chlorine)phenyl-2-amylamine·HCl) is a novel investigational anti-obesity drug without obvious cardiotoxicity. The objective of this study was to characterize the key physicochemical properties of JFD, including solution-state characterization
OBJECTIVE
The roles of vitamin D and parathyroid hormone (PTH) are discussed controversially in obesity, and studies of these hormones in obese children are limited. Therefore, we studied the relationships between PTH, 1,25-dihydroxy-vitamin D (1,25-OH Vit D), 25-hydroxy-vitamin D (25-OH Vit D),
BACKGROUND
Yucatán ranks first in the prevalence of urinary calculi (UL), and above the national average of obesity (OB). The aim of the study was to determine whether there is an association between obesity and metabolic disorders (MD) in patients with UL.
METHODS
In a case-control design, 197
OBJECTIVE
Several studies have reported that obese patients have a higher risk of nephrolithiasis. The purpose of this study is to investigate the effect of overweight (OW) and obesity on stone composition, type of treatment, and urine composition.
METHODS
With Institutional Review Board approval,
We explored the effects of insulin on mineral homeostasis in five lean and six moderately obese nondiabetic premenopausal women. Serum and urine minerals were measured before and during the steady-state phase of a euglycemic insulin clamp. Each subject participated in two insulin clamp studies on
Consecutive patients, between 18 and 54 years, suffering from morbid obesity (greater than or equal to 60 per cent overweight) are being randomized to either gastroplasty a.m. Gomez or to a very-low-calorie diet (341 kcal, 1.43 MJ) based on a high-value protein powder with an admixture of calcium,
BACKGROUND
The prevalence of vitamin D insufficiency and secondary hyperparathyroidism is high among morbidly obese subjects. Further, low serum levels of 25-hydroxyvitamin D (25 [OH]D) and magnesium have been associated with increased risk of the metabolic syndrome (MS), and recently, a possible
OBJECTIVE
To investigate whether osteoporosis occurs after surgical treatment for obesity.
METHODS
A cross-sectional study of five groups of subjects who had undergone surgical treatment for obesity: five pre-menopausal women; 13 post-menopausal women; seven post-menopausal women taking oestrogen
