Introduction: The prevalence of vitamin D deficiency is high, and yet still little recognized and treated. Cardiovascular diseases are the leading causes of morbidity and mortality worldwide and the emergence of evidence with the link suggesting an association between vitamin D deficiency and cardiovascular risk (CVR), it is pertinent to better understand this association.Objective: This study aimed to relate the levels of 25 (OH) D in obese patients wit...

Introduction: Familial chylomicronemia syndrome (FCS) is a rare inherited disorder of lipoprotein metabolism leading to severe hypertriglyceridemia and increased risk for acute pancreatitis. Mutations in the lipoprotein lipase (LPL) gene account for the majority of cases of monogenic chylomicronemia.Methods: We report the cases of two white males with a novel homozygous mutation in position 332 of the LPL gene.Res...

Introduction: Obesity has been associated with increased androgenicity in women, however there are conflicting data on this subject. Objectives: To determine whether any androgen is independently related to body mass index (BMI), waist-to-hip ratio (WHR) or age. To access if there is an association between elevated plasma androgen levels and the presence of either morbid obesity or metabolic syndrome (MS).Design and Methods: A total of 148 obese women we...

A positive association between thyrotropin (TSH) secretion and body-mass index (BMI) was previously reported. There are many studies concerning thyroid function in obesity, and some of them describe higher TSH levels in obese subjects.Evaluation of the hypothyroidism prevalence in a sample of obese women in their first obesity appointment at Hospital São João.Anthropometric variables and serum levels of TSH, free triiodot...

Introduction: Obesity is a heterogenous disorder. One of its subtypes that has been recently described is termed the metabolically healthy, but obese (MHO) individuals. Preliminary evidence suggests that this could be due to lower visceral fat levels and earlier onset of obesity.Objectives: To determine the prevalence of MHO in a sample of obese patients. To evaluate whether body mass index (BMI), waist circumference (WC) and waist-to-hip ratio (WHR) are...

Background: Bariatric surgery has been associated with a decrease in multiple obesity-related comorbidities including obstructive sleep apnoea syndrome (OSA). This study aims to access the OSA evolution in obese patients who underwent bariatric surgery.Methods: Retrospective longitudinal study of a population of obese patients who underwent bariatric surgery between January/2010 and July/2014 in our centre. Only patients who have undergone polysomnograph...

Introduction: The course of type 2 diabetes mellitus (DM) is insidious and, before its development, other glucose homeostasis abnormalities can be detected: impaired fasting glucose (IFG), impaired glucose tolerance (IGT) and elevation of HbA1c.Aims: To compare the prevalence of glucose homeostasis abnormalities in obese patients, using diagnostic criteria of American Diabetes Association (ADA) 2009, ADA 2010 and International Diabetes Federation (IDF) 2...

Introduction: Increased blood pressure (BP) above >115/75 mmHg presents an independent association with cardiovascular events. Although there is a clear benefit of bariatric surgery on BP of hypertensive patients, the impact in non-hypertensive patients remains largely unknown. Therefore, the aim of our work was to evaluate the impact of bariatric surgery on BP of non-hypertensive obese patients.Methods: We evaluated a cohort of 224 non-hypertensive ...
