Introduction: Most of pheochromocytomas (PCC) and paragangliomas (PGL) are sporadic. However, up to 40% of them have an inherited origin due to germline mutations in at least 15 known PCC/PGL genes, being the VHL and SDHx genes the ones most frequently affected. The fumarate hydratase (FH) is a Kreb’s cycle enzyme encoded by the FH gene.Its inactivating mutations increase intracellular levels of fumarate, leading to tissular pseudohypoxia and transcription of genes involv...

Introduction: Fine needle aspiration biopsy (FNAB) is the mainstay diagnostic procedure for evaluation of thyroid nodules, but it doesn’t permit to distinguish between benign and malignant follicular lesions (category IV in the Bethesda Cytopathology System). Some reports have suggested an association between increased serum levels of TSH and thyroid cancer. However, the specific relationship between TSH and malignancy has been scarcely studied in follicu...

Introduction: Achieving glycemic goals remains a challenge for many people with T1D despite recent technological advances. Integrated systems and closed loops pumps have shown significant improvements in glycemic control in clinical studies as well as in real life conditions.Objective: Assess the performance of the systems Tandem Control-IQ and DIABELOOP in people with T1D comparing the glucosa readings before and after having the device for 14 days....
