Paragangliomas (PGLs) and pheochromocytomas (PCCs) are rare tumors that arise from the neuroendocrine tissue along the paravertebral axis with the ability to secrete cathecolamines. Up to 33% of these tumors may be hereditary either alone or as a component of a multiple tumor syndrome. Germline SDHA mutations are relatively frequent (7.6%) in patients with genetically unexplained PGL, even in the absence of familial or clinical indications for inherited PGL....

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...

Background: the treatment of individuals with type 1 diabetes (T1D) has significantly evolved in recent years. Therefore, with the aim of achieving glycaemic targets to prevent or slow down the progression of the disease and its complications, hybrid closed-loop systems (AID) have been developed. These systems integrate three components: a continuous real-time glucose monitor, a control algorithm and an insulin pump. The objective of this study is to analyse the glycaemic and ...
