Obesity (OB) and type-2 diabetes (T2D) are chronic endocrine-metabolic diseases, associated to insulin-resistance (IR), that represent capital health problems. Fortunately, both pathologies are, at least, partially reversible by dietary interventions, but the potential metabolic, molecular, cellular factors and mechanisms that might be involved in the total/partial reversion of OB/IR/T2D by dietary interventions are poorly known. Thus, in this work, we aimed evaluate the impac...

Emerging evidence indicates that the cellular machinery controlling the splicing process (spliceosome) is altered in several tumour types, leading to oncogenic splicing events associated with tumour progression and aggressiveness. However, whether this molecular phenomenon also occurs in thyroid cancer has not been yet explored. Therefore, our main aim was to explore the potential dysregulation of the expression of relevant spliceosome components and splicing factors in clinic...

Emerging evidence indicates that the cellular machineries controlling gene expression mechanisms and genomic stability are altered in several endocrine-related cancers (ERCs), leading to some oncogenic events associated with tumour progression/aggressiveness. However, whether this phenomenon also occurs in thyroid cancer has not been yet explored. Therefore, this study was focused on: 1) investigating the potential alteration in the levels of components of the molecular machin...

Spindle cell oncocytoma (SCO) is a rare entity with just 18 cases reported in the literature. It was first described in 2002 and was codified as a separate diagnostic entity in the 2007 WHO classification of brain tumours. SCO is a nonadenomatous sellar neoplasm with rich vascularization and intra and supra-sellar infiltration. Usual clinical presentation consists of headache, visual field defects and pan-hypopituitarism. The preoperative diagnosis is difficult due to a lack o...

Introduction: Pheochromocytomas (PHEO) and paragangliomas (PGL) are rare catecholamine-secreting tumors. Some authors proposed that there is a positive linear relationship between tumor size and measurements of metanephrines and an absence of association with catecholamine levels.Objectives: To review and characterize patients diagnosed with PHEO and PGL in Garcia de Orta Hospital. To determine the relationship between tumor size and measurements of urin...

GH deficiency (GHD) in adults is characterized by a tendency towards fat mass gain and may predispose to type 2 diabetes mellitus.GH replacement (GHR) is associated with impaired insulin sensitivity shortly after starting therapy, reflected by increased fasting glucose and insulin levels. Available evidence suggests that concerns regarding glucose intolerance in patients receiving long-term GHR have not been substantiated. However, several environmental and lifestyle-related f...

Introduction: Flash glucose monitoring expansion to an increasing number of patients with type 1 diabetes, coupled with its increased accuracy and ease of use, has increased available data on glycemic control in this population and allows detection of improvement areas in diabetes education and treatment.Objective: To analyze main parameters standardized by ATTD consensus (2019) in our population of patients with type 1 diabetes using flash glucose monit...

Introduction: Subclinical hypothyroidism (SCHT) in pregnancy has been associated with adverse obstetric and perinatal outcomes. However, few studies have investigated the evolution of postpartum thyroid function in women first diagnosed with SCHT in pregnancy (gestational SCHT).Objective: To determine the evolution of thyroid function (TF) and the clinical and biochemical factors related to the long-term persistence of hypothyroidism (HT) in women with g...

Objective: Owing to their remarkable stability in the serum, microRNAs are being investigated as circulating cancer biomarkers. Several studies have explored their plasma or serum levels in thyroid cancer in order to differentiate benign from malignant nodules preoperatively. However, very few studies have explored the role of microRNAs to detect recurrent disease during postoperative follow-up and none of them used high through-put technologies. Recombinant human TSH (rhTSH) ...
