Paraganglioma (PGL) are rare neuroendocrine tumors with an estimated prevalence of 1:6500, with cardiac PGL being even rarer. Although most PGL are benign, approximately 15–35% of PGLs have metastatic disease, with few effective treatment options. Novel therapeutic indications, such as 177Lu-DOTA-TATE for patients with PGL, has been investigated in several clinical trials. A 66-year-old woman was referred to Cardiology in 2011 due to an incidentaloma adjacent to the right...

Background: Children who were born small for gestational age (SGA) and who do not have adequate catch-up growth until 4 years old have indication for treatment with recombinant human growth hormone (rhGH). The metabolic consequences of this treatment are relatively unknown. Objective: To evaluate the effect of rhGH treatment on insulin sensitivity and lipid profile.Materials and methods: A retrospective observational study of child...

Introduction: Current guidelines recommend a single prolactin sampling for the diagnosis of hyperprolactinaemia. Nonetheless, in some patients, prolactin levels may normalize in a subsequent sampling or if prolactin is collected through a venous catheter some time after puncture. We aimed to assess the percentage of patients in which prolactin remained elevated in repeated sampling and to determine the best prolactin cutoff associated with persistent hyperprolactinaemia.<p...

IntroductionSimultaneous pancreas-kidney transplantation (PKT) has a beneficial effect on the evolution of chronic complications in type 1 diabetic (T1D) patients with terminal chronic kidney disease (CKD). However, the CKD-mineral and bone disorder (CKD-MBD) remains a frequent complication. There are a few studies addressing the long-term evolution of bone mineral density (BMD) in these patients.AimTo charac...

Introduction: Primary adrenal insufficiency (PAI) is a rare but severe and potentially life-threatening condition. There are no studies characterizing portuguese patients with PAI.Aims: To characterize the clinical presentation, diagnostic workup, treatment and follow-up of patients with confirmed PAI.Methods: A multicentre retrospective study of PAI patients followed in 12 portuguese hospitals.Results: We in...

Introduction: Bariatric surgery is associated with improvement and often resolution of type 2 diabetes mellitus (T2DM). Our aim was to compare the effects of gastric banding (GB) and gastric bypass (GBP) in glucose homeostasis in obese patients with T2DM.Methods: From 1995 to 2011, 83 diabetic patients underwent bariatric surgery at our hospital: 37 underwent GB (73% females, mean age 48.3±9.2) and 46 underwent GBP (82.6% females, mean age ...

Introduction: Continuous glucose monitoring systems (CGM) have revolutionized the monitoring of diabetes, allowing real-time measurement of interstitial glucose levels. Although these devices are suitable for patients on insulin therapy, they are not yet routinely used in an inpatient setting. The difficulty observed in the glycemic control of hospitalized patients under intensive insulin therapy led to the development of a protocol to study the application of CGM in these pat...

Introduction: In 2020, a group of experts proposed to change the term “non-alcoholic fatty liver disease” (NAFLD) to “metabolic-associated fatty liver disease” (MAFLD), which includes hepatic steatosis (HS) (using imaging or analytical scores) associated with overweight or obesity, type 2 diabetes (T2D), or the presence of two other metabolic disorders.Objectives: Analyse the impact of bariatric surgery on MAFLD.<p class="abstext"...

Wearable physical activity monitors are growing in popularity as they provide the opportunity for self-monitoring, real time data collection and data sharing for cardiovascular and sports medicine. However, there are discussions about the accuracy of their energy expenditure estimate. This study examined and compared basal metabolic rate through indirect calorimetry and through wrist-worn devices and bioimpedance. The group consisted of 30 healthy male individuals, professiona...

The recombinant human interferon α-2a (rhIFN α-2a) is a cytokine with antiviral, antiproliferative and immunomodulatory properties, indicated for the treatment of hepatitis B and C and leukemias. The rhIFN α-2a consists of a 165–166 amino acids with molecular mass of 19.5 kDa. The aim of this work was to develop and validate the reversed-phase (RP-LC) and size-exclusion (SE-LC) liquid chromatography methods for the physico-chemical characterization of rhIFN...
