Introduction and Objectives: Preperitoneal fat is an ectopic visceral adipose tissue with a significant proinflammatory metabolic impact. The objective of this study is to measure preperitoneal fat by nutritional ultrasound at discharge, 3 months and 6 months in a cohort of patients who required admission to the Intensive Care Unit (ICU) due to severe COVID-19 pneumonia, and to analyze the differences based on the presence or not of previous DM.Material ...

Background: Type III gastric neuroendocrine neoplasms (g-NEN) are usually lesions of higher grade and often associated with loco-regional and distant metastases. Guidelines recommend partial or total gastrectomy with local lymph node resection. Data for less-extensive resections are limited.Aim: To assess whether advanced endoscopic excision [Endoscopic Mucosal Resection (EMR) or Endoscopic Submucosal Dissection (ESD)] or localized surgical approach (wed...

Introduction: Breast cancer is, by far, the most frequent cancer among women. Local and systemic factors have been shown to drive growth in breast cancer cells. There is increasing evidence that hormone ghrelin, known for the growth hormone releasing effect and food intake modulator, may also influence cancer growth. Ghrelin has been shown to be produced by some tumor cells, including breast cancer cells.Objective: To analyze ghrelin expression in correl...

Introduction: The prevalence of transsexuality in Europe is uncertain in absence of epidemiological studies, so it’s difficult to implement public healthcare strategies.Aim: To describe healthcare demand evolution in a gender identity clinical service in our country.Methods: Our center is a public university hospital placed in Valencia (Spain). It is a reference center on gender dysphoria from two provinces (Valencia and Caste...

Introduction: Paraneoplastic Cushing’ syndrome (CS) represents 5–10% of all CS and has a severe prognosis due to severe metabolic imbalance, denutrition, associated infections, and progression of tumoural underlying pathology.A 67 years old woman presented with mental confusion, progressive weight loss, severe oedema and kypokalaemia, without typical features of Cushing or hyperpigmentation. Investigations revealed paraneoplastic Cushing’s...

Introduction: The main indications for the somatostatin analogues (SST-A) are acromegalies and/or neuroendocrine tumors. They can increase fecal fats, which could lead to the loss of fat soluble vitamins. There are few published studies showing the effects of the long-term use.Methods: Retrospective study of patients with SST-A indicated from our endocrinology department in the last 10 years. We analysed indications and different epidemiological, clinica...

Introduction: Ghrelin, a peptide hormone produced in the stomach, stimulates secretion of growth hormone and regulates appetite and energy homeostasis. Various other effects attributed to ghrelin may contribute to many aspects of cancer development and progression.Material and Methods: Using polyclonal antibody immunohistochemistry, we assessed (by intensity scoring) the immunolocalization of ghrelin in 70 tissue samples, and described particularities wi...

KNDy neurons, which co-express kisspeptins, neurokinin B (NKB) and dynorphin (Dyn), play a key role in the tonic control of gonadotropin secretion by modulating the GnRH release. The assumed KNDy model proposes that NKB and Dyn (as stimulatory and inhibitory signals, respectively) auto-regulate the secretion of kisspeptins onto GnRH neurons. However, some aspects of this paradigm remain poorly defined. In this context, the aims of this work were to characterize i) the putative...

Introduction: Increased capacity for glucocorticoid regeneration in subcutaneous adipose tissue (SAT) by 11β-hydroxysteroid dehydrogenase-1 (11HSD1) is associated with obesity and associated risk factors. We hypothesised that down-regulation of SAT 11HSD1 and/or glucocorticoid receptor-α (GRα) may explain differences in body fat distribution and metabolic risk between black and white women. The study aimed to compare the expression of 11HSD1 and glucocorticoid r...

Background: Low thyroid hormone concentrations in the first few weeks of life in preterm infants may be linked with poor neurodevelopment. We conducted a multi-centred randomised controlled trial of thyroxine (T4) supplementation in babies born under 28-weeks’ gestation (TIPIT study). A post hoc subgroup analysis was undertaken to examine brain growth and development.Methods: Seventy-eight infants received T4 supplementation an...
