Objectives: To determine the habits and lifestyle of the morbidly obese before and after bariatric surgery.Material and methods: Transversal study of two groups of morbidly obese patients attending the Endocrinology Unit of Puerta del Mar, Cádiz: one group before and the other after bariatric surgery. Clinical and analytical data of the patients was collected: socio-demographic and lifestyle characteristics, Bulit-R Questionnaire (Bulimia), BIS (imp...

Cellular reprogramming describes the process where a fully differentiated, specialized cell type is induced to transform into a different cell. Cell reprogramming techniques can become powerful tools for modelling diseases, drug testing and for personalized cellular therapy. The adrenal cortex is the primary site of steroid synthesis. Adrenal insufficiency, which can be life threatening, is caused by a number of adrenal disorders, and lifelong management of these patients with...

Introduction: Activation of the hypothalamic–pituitary–adrenal axis is critical for adaptation to stress and serious illness. The imbalance between anti-inflammatory activity of cortisol and proinflammatory activity of the androgens, dehydroepiandrosterone (DHEA) and dihydroepiandrosterone sulfate (DHEAS) can be an important predictor factor of mortality in sepsis.Material and methods: Patients diagnosed of severe sepsis or septic shock admitte...

The G protein-coupled receptor (GPCR) kinase 2, GRK2, is a ubiquitous serine/threonine protein kinase that is able to phosphorylate and desensitize the active form of several GPCR. Compelling, as yet limited, evidence from in vitro studies have suggested a potential role of GRK2 in mediating desensitization of Gpr54, the canonical receptor for kisspeptins that is abundantly expressed in GnRH neurons. Yet, although kisspeptins have been universally recognized as essent...

Background: Previous studies of association between maternal thyroid autoimmunity and adverse pregnancy outcomes have produced inconsistent results.Objective: To examine whether thyroid autoimmunity detected at first trimester screening is predictive of a range of adverse obstetric and fetal outcomes.Patients and methods: We studied 438 women with singleton pregnancies who underwent first trimester screening test between June and J...

Introduction: Hypoaldosteronism (HA), a cause of hypovolemic hyponatremia (HN) with urinary(U) sodium(Na) loss, is often underdiagnosed. We studied 28 patients with an episode of HA-induced moderate/severe hyponatremia.Methods: Retrospective 2012–2015. In all patients, Nadir(N) serum(S) Na <130 mmol/l (corrected for total proteins and glycemia), low internal yugular venous pressure, low ocular pressure. Addison’s Disease ruled (ACTH, cortis...

Aims: There are few data comparing oxidative stress markers in CSII versus MDI/G We compared after randomization CSII (Continuous subcutaneous insulin infusion) vs MDI/G therapy (multiple doses of insulin with glargine) in DM1 people previously optimized at MDI/G being the primary objective assessment of metabolic control and oxidative stress.Assess oxidative stress and metabolic control in patients with type 1 diabetes (T1D) after randomization in CSII ...

Introduction: Hereditary phaeochromocytoma (PCC) and paraganglioma (PGL) account for 30–35% of cases and have some clinically relevant peculiarities.Material and methods: Retrospective, unicentric cohort study that included all genotyped patients (n=36, 27 with PCC and 9 with PGL) diagnosed at Hospital Clínico San Carlos (Madrid) between 1984 and 2013; 33% were germline mutation carriers (25% pseudohypoxic [PH] phenotype, 75% MAP-kinas...

Introduction: Hereditary Medullary Thyroid Cancer (MTC) accounts for 20–30% of cases and has some clinically relevant peculiarities.Material and methods: Retrospective, unicentric cohort study that included all genotyped patients with MTC (n=48) diagnosed at Hospital Clínico San Carlos (Madrid) between 1984–2013; 42% were germline mutation carriers (45% moderate risk (category MOD), 45% high risk (category H), 10% highest risk (ca...

Introduction: ESE guidelines state a risk for overcorrection of serum sodium levels (SNa) with vaptans. We present the results of our protocol for initiation of tolvaptan(TV) therapy in SIADH.Methods: Retrospective (2011–15). 86 patients with SIADH-induced mild/moderate hyponatremia received TV:7.5 mg day 1, ad-libitum liquids, no other Na-raising therapies. Conventional hospitalization (CH):66/86, day hospital (DH):20/86. Glycemia-corrected SNa det...
