Aim: Describing bariatric surgery (BS) interventions in our center in the last five years, complications and effectiviness in weight loss and resolution of comorbities.Methodology: Prospective descriptive study on a cohort of people who underwent BS surgery at Virgen Macarena University Hospital, a tertiary hospital of the Public Health System of Andalusia, between January 2018 and May 2023. Patients who underwent revision surgery with a first previous s...

Aim: Illustrating a case series of two patients with levothyroxine malabsorption and suboptimal control of the thyroid profile who experienced a significant improvement after switching to liquid levothyroxine.Material and Methods: Case saries of two patients who were attended in monographic thyroid pathology consultations at Virgen Macarena University Hospital.Results: Case 1: a 46-year-old female patient who had multinodular goitr...

Introduction: Sarcoidosis is a rare systemic disease where clusters of immune cells form granulomas in various organs of the body. Its prevalence ranges from 1-40 per 100,000 people in Europe. Neurological involvement of the disease occurs in 5-10% of cases, with the hypothalamus-pituitary gland being one of the most commonly affected structures.Clinical Case: A 36-year-old male with a history of hypertension, obesity, asthma and OSAS. He went to the eme...

Background: It is well established that life-long follow-up is required for patients with hereditary pheochromocytomas and paragangliomas (PPGLs), due to the potential of developing recurrent disease. However, whether follow-up of patients with sporadic PPGLs is necessary, remains unclear.Aims: To examine the prevalence and predictors of recurrent disease in patients with sporadic PPGLs.Materials and method: This multicenter study included retrospective ...

Pheochromocytomas and paragangliomas (PPGL) are commonly benign catecholamine-producing neuroendocrine tumors (NETs); however, up to 25 % of patients develop distant metastases or aggressive behavior. The current classification of PPGL comprises pseudohypoxia-profile, MAPK-pathway alteration, and Wnt-pathway dysregulation clusters according to their genomic characterization. However, to date, there are no biomarkers to help stratify patients based on their prognosis. Alternati...

Pheochromocytomas and paragangliomas (PPGLs) are rare neuroendocrine neoplasms (NENs) that arise in the adrenal medulla and paraganglia, respectively. As occurs in the rest of NENs, PPGLs commonly present a high density of somatostatin receptors (SSTs) on their membrane. However, unlike in most NENs, somatostatin analogues (SSAs) do not represent a suitable therapeutic target in PPGLs, and the mechanisms underlying this mismatch are still unclear. In this study, we aim to iden...

Pheochromocytomas and paragangliomas (PPGL) are infrequent neuroendocrine neoplasms, which develop metastases or aggressive behaviour in 25 % patients. They can be classified into three clusters according to their molecular features; nevertheless, these differences may not stratify patients according to their prognosis. The dysregulation of the splicing process has emerged as a novel feature shared by most cancers, which is associated with an aggressive phenotype in several tu...

Introduction: Detransition is the act of stopping or reversing a gender medical, social or surgical transition. The study’s purpose was to describe our experience with a group of transsexual people in detransition phase.Material and methods: A cohort of 204 people with gender incongruence attending the Identity Gender Unit Hospital Clinico of Valladolid from January 2014 to December 2022 was studied. Seven of those participants detransitioned and we...

Dysregulation of the splicing machinery is emerging as a novel cancer hallmark due to its association with multiple dysfunctions in tumor cells. An inappropriate function of the components of this machinery (spliceosome) could be primarily linked with the generation of tumor-associated aberrant splicing variants. In line with this, we have previously reported that overexpression of aberrantly spliced variants of somatostatin receptor 5 (sst5TMD4) and ghrelin (In1-ghrelin) is d...

: Hepatic steatosis is a common obesity-associated pathology characterized by the accumulation of fat within the liver, which can progress to liver fibrosis, cirrhosis and ultimately lead to hepatocellular carcinoma. Remarkably, obesity and cancer course with a profound dysregulation of the genetic expression patterns and, particularly, with the aberrant expression of splicing variants that could contribute to the aggressiveness and comorbidities of these pathologies. Since th...
