Obesity is growing fast worldwide. Although environmental factors play a major role, endocrine dysfunction may contribute to the weight gain. We report an invasive macroprolactinoma diagnosed in obesity setting. A 35-year-old male was referred to our endocrine outpatient department due to grade 2 obesity (IMC 38.4 Kg/m2). His weight was increasing since the beginning of his professional activity at the age of 20 due to a sedentary lifestyle. On physical examination he had an h...

Aim: Dose corrected for thyroid gland size is one of the methods used to determine radioactive iodine (RAI) activity for patients with Graves disease (GD). This study was aimed to investigate the real-world success rate of this method and the predictors of success after first treatment.Methods: This is a retrospective study of 80 patients with GD treated between 2014 and 2020 in a tertiary referral hospital in Almada, Portugal. The successful group was d...

Introduction: The best timing for PRRT (peptide receptor radionuclide therapy) in the case of pancreatic neuroendocrine tumors (panNETs) is still to define, as randomized prospective trials are lacking. Recent studies suggest that some systemic therapies can affect response to PRRT, favoring an earlier use of the latter.Objective: To determine the efficacy and toxicity of PRRT, comparing its results when used as a second line systemic therapy (a...

Background: Papillary thyroid cancer (PTC) is the most frequent type of well-differentiated thyroid cancer (WDTC) and frequently poses a management dilemma. Its indolent behavior associated with high long term survival support the trend towards a more conservative management approach. The authors present a case of isolated bone metastases as the form of presentation of papillary thyroid carcinoma. A 61-year-old man was admitted with complaints of lower back pain for the previo...

Introduction: Intrauterine growth is a biological process regulated by maternal, placental, and foetal endocrine signals. Birth weight is an indicator of the health of the newborn. Alterations in foetal growth lead to perinatal health risks and favour metabolic diseases during adult life. Therefore, the study of endocrine factors determining birth weight, such as ghrelin is an important issue. Ghrelin may exist as two molecular forms, desacyl ghrelin (DAG) and acyl ghrelin (AG...

Background: Residual C-peptide (CP) secretion has been associated with better glycemic control in patients with type 1 diabetes (T1D).Aim: To evaluate how residual fasting CP (fCP) secretion impacts glycemic control in T1D and to identify possible confounding factors.Methods: A retrospective analysis of adult patients with T1D followed in our department that had their fCP and glucose levels obtained on the same blood sample during ...

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...

Background: The use of Flash Glucose Monitoring (FGM) for the management of type 1 diabetes mellitus (T1D) is rapidly increasing.Aims: To assess the longitudinal evolution of glycated haemoglobin (HbA1c) and body mass index (BMI) with the use of FGM in patients with T1D; to determine predictive factors of benefit with the use of this technology.Materials and methods: Retrospective study of T1D patients, using FGM ≥6 months an...

Obesity is the single most significant risk factor for testosterone deficiency in men, with a reported prevalence up of 60% of male obesity secondary hypogonadism (MOSH). Several studies have shown that significant weight loss due to bariatric surgery have significant metabolic and endocrine improvement in obesity, however the results achieved with conventional diet and lifestyle change are poor and not able to reverse this condition. As an alternative to bariatric surgery, we...

Introduction: GH deficiency (GHD) in adults is associated with low serum levels of insulin-like growth factor 1 (IGF1) and a deteriorated cardio-metabolic profile. GH replacement therapy (GHRT) increases serum IGF1, an important mediator of the treatment response and safety marker of dose titration. The interindividual variation in treatment response is large and most likely influenced by genetic factors.Aim: The aim of this study was to test the hypothe...
