Introduction: Type 2 diabetes mellitus is a conformational disease (CD), characterised by deposition (fibrils and cytotoxic oligomers) of the human islet amyloid peptide (hIAPP). CDs have devastating effects on the sufferers and their caregivers, as well as a tremendous economic impact on families and the health system. Novel molecule candidates targeting self-assembled amyloidogenic proteins represent a potential therapeutic approach for CDs.Methods/des...

Introduction: The global patterns of aberrant DNA methylation in thyroid cancer are not known. In this study, we have used DNA methylation arrays to determine, for the first time, the genome-wide promoter methylation status of different subtypes of thyroid tumors.Material and methods: We analyzed a cohort of 54 snap frozen thyroid samples (thirteen papillary tumors, six follicular, eleven anaplastic, twenty medullar and four normal tissue samples). Also ...

Introduction:Type 2 Diabetes (T2DM) almost doubles the risk of comorbid depression, with lifetime prevalence up to 29%. It is important to recognize and treat depression in T2DM because its association with hyperglycemia, increased diabetic complications and poor quality of life (QoL) is well established. However, currently available medical therapy for depression is effective in reducing depressive symptoms, but does not consistently improves HbA1c levels. Aims:Determine the ...

Introduction: Melanocortin-4 receptor (MC4R) is a G-protein-coupled receptor expressed in regions of the hypothalamus regulating appetite and energy expenditure. Extensive evidence from genetic and biological studies show that MC4R is a key player in the homeostatic regulation of body weight. MC4R loss of function (LoF) variants are the most common cause of monogenic obesity. We have identified 13 heterozygous MC4R variants in patients with obesity at our academic Obesity Cent...

Background: The indication of ablation with I131 in low-risk DTC is controversial. The exact dose needed for thyroid remnant ablation is still a matter of debate in low-risk DTC patients. However, low dose has been found to be equally effective as high dose in terms of recurrence rate in recent studies. Taking this into account the current trend is to administer lower doses, although some studies describe a higher rate of retreatment.Aims: 1. To examine ...

Introduction: The parathyroid gland is made up of principal cells and oxyphilic cells, surrounded by stroma, whose main component is adipose tissue, which accounts for 25% of the content of the parathyroid in adults. In parathyroid adenomas, prominent parathyroid cellularity can be observed, with a very marked decrease in the stroma. Parathyroid lipoadenoma is a rare variant of parathyroid adenoma, characterized by hyperfunctioning parathyroid cells in an abundant fatty stroma...

Introduction: Insulinomas are pancreatic neuroendocrine tumors (PNET), characterized by insulin hypersecretion syndrome with the development of hypoglycemia. The incidence of the tumor is 3-10 cases per million inhabitants. The average age of onset is 40-50 years old, being more frequent in women. Case Reports: We present a clinical case of a patient with CREST syndrome and difficult-to-control hypoglycemia. Female patient, 81 years old, with a history o...

Background: Autonomic hyperfunctioning thyroid nodules account for approximately 5% to 10% of all thyroid nodules. Compared with non-toxic nodules, hot nodules are traditionally believed to have an exceptionally low malignancy rate, and this has led to recommendations not to perform fine-needle aspiration (FNA) on these lesions, regardless of their size. However, recent studies have questioned the presumed low risk of malignancy in hot nodules, suggesting that the incidence of...

Objective: The carbohydrate metabolism dysfunctions are common in critical ill patients with diabetes or stress hyperglycaemia and the correct management of them has an important prognostic value. Despite its limitations, capillary glucose (CG) was collected more than arterial glucose (gold standard) because of its good correlation. However, the usefulness of intermittent intersticial glucose monitoring (IGM) in keeping blood glucose within target range in critical ill patient...

Introduction: In Spain, the specialist in endocrinology and nutrition is the reference in the care of patients with diabetes mellitus. In the year 2022, access to these specialists has been facilitated in the south of Gran Canaria. The aim of the study is to determine how this has influenced the management of type 2 diabetes (T2D).Methods: We included those patients with T2D assessed by the Endocrinology service in 2022 in which two analyses were perform...
