Introduction: HO1 is a new adipokine with a protective role against cellular stress and hypoxia1. MO presents with high low grade inflammation (LGI)2 and high circulating levels or adipose tissue expression of HO13. The effect of bariatric surgery on HO1 and its relationship with OSA and LGI has not yet been studied.Methods: We studied 66 MO patients before and 1 year after BS. All of them presented OSA without Continuous...

Introduction: Prader Willi syndrome (PWS) is the most common syndromic form of obesity, caused by the absence of expression of the paternally active gens on the long arm of chromosome 15.The 16p11.2 microdeletion has recently been recognized as a syndromic condition appearing to be a predisposing factor for overweight, being the second most common genetic cause of obesity. One possible causative gen- SH2B1- involving leptin and insulin signaling, has been identified, although ...

Introduction: Decreased bone formation has been proposed as a mechanism involved in the higher risk of fractures in diabetic patients. Some clinical studies have found that sclerostin (SCL, a negative regulator of bone formation) is increased in diabetic patients. However, there is no information about the relationship between SCL and new onset diabetes after transplantation (NODAT). The aim of our study is to evaluate serum SCL levels in a cohort of patients with liver transp...

Metabolic syndrome and obesity are principal causes of morbidity all over the world, particularly for their association to cardiovascular risk. There is now an obesity worldwide epidemic (Globesity). Amerindians are often living in countries and remote areas with unavailable sophisticated diagnoses methodologies. However, waist circumference is a reliable and easy to record parameter of visceral obesity and MS. Waist circumference normal values are not yet established in Ameri...

Introduction: Primary aldosteronism (PA) causes 15–25% of cases of drug-resistant hypertension (RBP). Adrenal vein sampling (AVS) is considered the gold standard for diagnosis of aldosterone aberrant secretion origin. The distinction between unilateral and bilateral disease dictates the targeted therapeutic approach, with surgery for aldosterone producing adenomas and medical therapy for patients with bilateral hyperplasia. As AVS is an invasive, not well standardized pr...

Background and aim: Obesity (Ob) is tightly associated with metabolic diseases such as type 2 diabetes (DT2) andinsulin resistance (IR). Furthermore, obesity has been identified as one of the primary causes of mood disorders (MDs) including depression. Several studies have demonstrated the link between Ob, adiposity, neuroinflammation and MDs. The Brain-Derived Neurotrophic Factor (BDNF) and its regulator, the non-coding RNA BDNF antisense RNA (BDNFas), play an import...

Background: Prader-Willi syndrome (PWS) is a genetic neurodevelopmental disorder characterized by marked hyperphagia and morbid obesity, together with hormone deficiencies, abnormal behaviour in relation to food (obsessive thinking, food foraging, stealing, etc.). Veins in patients with PWS are difficult to find due to obesity and probably to generalised hypotonia including venous tone. Since treating a patient with PWS often requires the acquisition of blood samples, an exper...

Development of type-2 diabetes (T2D) is critically affected by the loss of phenotypic flexibility. There is emerging evidence suggesting that, under adverse metabolic conditions, alternative mRNA splicing is markedly dysregulated at different levels. For this reason, we hypothesized that such dysregulation could contribute to loss of phenotypic flexibility. Consequently, we aimed to explore whether changes in the splicing machinery in peripheral blood mononuclear cells (PBMCs)...

Aim: Non-alcoholic fatty liver disease (NAFLD) and type 2 Diabetes (T2D) are common conditions that frequently co-exist. Studies have shown an increase likelihood of micro and macrovascular complications in this population, as well, as an increased risk of developing more severe forms of liver disease. The aim of this study was to identify diabetic complications in patients with both diseases and search for an association with liver stiffness assessed by Liver Elastography (LE...

Obesity, a multifactorial chronic endocrine-metabolic disease, represents one of the most serious and complex global health threats, as it is commonly associated with multiple and severe comorbidities (e.g. diabetes type-2). Indeed, as a source of severe metabolic-dysregulation, obesity alters physiological, homeostatic gene expression patters in multiple metabolic-tissues, including the central metabolic hub, i.e. the liver. However, the precise molecular mechanisms underlyin...
