Aim: To analyze the influence of bariatric surgery over serum lipids in patients with morbid obesity after 1 year of surgery.Methods: Retrospective study of 88 patients before and after 1 year of bariatric surgery (65 by pass and 23 sleeve). We collected data about age, sex, other diseases, anthropometric measures and biochemical parameters: glucose, uric acid, total cholesterol (TC), HDL-C, LDL-C, triglycerides (TG), VLDL and non-HDL-C, homocistein and ...

Introduction: Somatostatin (SST) is a widely distributed polypeptide that modulates the endocrine and exocrine secretion, cellular proliferation and differentiation, and apoptosis via G protein-linked receptors. Our previous studies showed high SSTR expression in adrenocortical carcinoma (ACC), aldosterone producing adenoma (APA) and in cortisol producing adenoma (CPA). Only very few information are available about the effectiveness of SST analogs in adrenal tumors.<p clas...

Estrogens play a protective role on the peripheral vascular endothelium in both females and males, however, no studies have reported on the effects of estrogens on male coronary arterial reactivity. We investigated the effects of estrogen therapy on coronary and endothelial function in a group of male to female transsexuals (M-to-F).Eight M-to-F transsexuals (group A), receiving oral estrogen therapy for 72 months were studied in comparison with 23 age-m...

Overweight and obese subjects often suffer from hypoglycaemic symptoms due to hyperinsulinemia. This increases subjects’ need to eat excessive amount of food enriched in sugar causing rebound hyperglycaemia which in turn stimulates endogenous insulin release perpetuating a vicious circle that limits weight loss under diet restriction programme. Two previous studies showed that administration of Glucose RapidSpray™ (GRS) in quantity of ~ 0.5 g increases blood glucose ...

Background: Diabetes is an important risk factor for major adverse cardiovascular events (MACE). Although the increased risk for MACE is well known, the impact on the in-hospital outcomes remains incompletely understood. Our aim was to evaluate the interrelation between diabetes and MACE in a central hospital in the North of Portugal between 2009 and 2015.Methods: We evaluated retrospectively the hospitalizations due to MACE including stroke or transient...

Objectives: To evaluate changes in gonadotrophins, total (TT) and free (FT) testosterone, SHBG, insulin and c-peptide levels during weight lost after bariatric surgery.Material and methods: Seven (n=7) patients submitted to bariatric surgery for treatment of severe obesity were followed-up over time. Before surgery mean age was 32,857 (19-56) years old, mean weight was 170,571 kg (± 37,362) and mean BMI was 58,824 kg per m2(± 14,...

Small fish are excellent experimental models to screen endocrine-disrupting compounds, but current fish-based assays to detect endocrine disruption have not been standardized yet, meaning that there is not consensus on endpoints and biomarkers to be measured. Moreover, exposure conditions may vary depending on the species used as the experimental model or the endocrine pathway evaluated. Another drawback is the fact that most methods to detect endocrine disruption rely on the ...

Aim: The aim of this study was to evaluate the association between thyroid function in Graves’ disease (GD) with high-sensitivity C-reactive protein (hs-CRP), lipid profile, homocysteine, folate, vitamin B12 and insulin resistance.Methods: We performed a cross-sectional of 104 patients with recently diagnosed GD. All participants were in the first cycle of treatment with methimazole. We collected demographic information, body mass indexes (BMI), lab...

Introduction: Obese patients are at an increased risk of develop nonalcoholic fatty liver disease. Evidence supports that bariatric surgery might have an important impact on hepatic profile in obese adults. Literature suggests that bariatric surgery in adolescents might decrease the prevalence of some comorbidities, but information about its impact on liver profile and steatosis and fibrosis risk remains scarce.Aim: To evaluate the impact of bariatric su...

Introduction: Obesity is a complex multifactorial disease and its prevalence in pediatric age has increased. Obesity prejudices the individual metabolic profile due to the adipotoxicity involved in this condition. Bariatric surgery improves the weight of obese patients along with metabolic comorbidities, being today one of the most effective treatments for obesity. Time of exposure to adipotoxicity appears to be an important risk factor for the development of metabolic complic...
