Aim: Bone turnover markers (BTMs) predict more rapid rates of bone loss. However, most of these studies have been carried out in postmenopausal women. Few prospective studies have examined the degradation marker C-terminal telopeptide of type I collagen (CTX) and the bone formation marker N-aminoterminal propeptide of type I collagen (P1NP) measured during the menopausal transition to predict the subsequent bone loss.Methods: We performed a prospective c...

Background: There is a clear relationship between obesity and carbohydrate metabolism alterations (CMA), such as impaired glucose tolerance (IGT) and T2D. OGTT is used for the diagnosis of those alterations, but is not performed in case of normal fasting glucose values (NFG). Moreover, BMI underestimates the diagnosis of obesity and body composition alteration can be crucial to the development of abnormal carbohydrate metabolism. This study aimed to examine the discriminating ...

Obstructive sleep apnoea (OSA) is very common in severe obese patients and has been related to insulin resistance (IR) and hyperleptinemia, and these findings may have effects on food behavior and obesity complications. In order to explore this relationship and the role of sex we have studied 531 patients with morbid obesity (BMI 42.8+6.5 kg/m2). A full polysomnographic study and glucose, insulin and leptin measurements as well as air displacement plethysmography we...

Morbid obesity (MO) is often complicated by obstructive sleep apnoea (OSA), which in some cases is evaluated by pulsioximetry. This cross-sectional study was designed to investigate the prevalence of discordance between desaturation index (DI) and apnoea–hypopnoea index (AHI) and its effects on insulin resistance and secretion in MO patients candidate to bariatric surgery (n=496) in whom a full polysomnographic study was carried out. We identified 163 (33%) out o...
