Introduction: Calcitriol-mediated hypercalcemia is one of the most common paraneoplastic syndromes associated with lymphoma.Aim: Evaluate clinical and biochemical manifestations as well on the management of hypercalcemia in patients with lymphoma.Materials and methods: Prospective analysis of patients with lymphoma who developed hypercalcemia during September-2011 and January-2016.Results: Two hundred and six...

Introduction: Classically, risk stratification in papillary thyroid carcinoma (PTC) assigned the same magnitude of risk to all patients with regional lymph node involvement (N1 disease). However, specific lymph node characteristics (such as size, number, extension, etc.) will allow individualizing treatment and follow-up. One-Step Nucleic Acid Amplification (OSNA) measures the number of copies of mRNA of cytokeratin 19 (CK19) as a marker of lymph node metastasis. Thus, copy nu...

Introduction: Diabetes Mellitus (DM) and prediabetic states (pre-DM) are well known risk factors for stroke. Admission blood glucose level and its control during hospital stay, help predicting arterial recanalization after thrombolysis and middle and long term prognosis. We analysed recurrence, mortality and nosocomial infectious complications in DM, pre-DM and patients without previous or newly diagnosed DM or pre-DM.Methods: Descriptive analysis in con...

Introduction: 25-hydroxyvitamin D (25(OH)D3) deficiency has been associated with diabetes and obesity. However, the mechanisms underlying these relationships are not completely understood. Vitamin D receptor (VDR) is expressed in adipose tissue; it has been reported a higher expression in obese patients than in lean subjects, suggesting a differential vitamin D dynamics in adipose tissue according to the obesity degree. In addition, 1, 25-dihydroxyvitamin D3 (1,25(OH)2D3) is a...

GLP-1 is a gut hormones with insulinotropic effects. GLP-1 is expressed at the hypothalamus having regulatory functions in food intake and neuroendocrine corticoadrenal axis (HPA). Energy balance and HPA have deep influence in the gonadal function of mammals. Exendin-4 (Ex4) is a potent agonist for the GLP-1 receptor.Objectives: To evaluate the effects of native GLP-1 (7–36)-NH2(GLP-1) and Ex4 in the function of the reproductive system in adulthood ...

Introduction: Alterations in foetal growth lead to neonatal health risks and favour metabolic diseases during adult life. Therefore, the study of birth weight determination and its modifications is crucial for metabolic diseases prevention. Placental growth is a key factor in foetal growth. It has been suggested that insulin and the IGF system play an important role in foetal growth and placental development and function. Although, insulin and IGFs in the umbilical cord blood ...

Introduction: Hyponatremia is the most common electrolyte imbalance among hospitalised patients. Syndrome of inappropriate antidiuretic hormone secretion (SIADH) is considered the most frequent etiology on patients with euvolemic hiponatremia. Conventional treatment includes water restriction and salt tablets with limited efficacy and very slow onset of action in certain patients.Material and methods: Systematic sampling of all SIADH patients treated wit...

Background: Recent studies have shown that the incidence of differentiated thyroid cancer (DTC) is increasing.Objective: Evaluate the incidence of DCT in a center of the south of Spain for the last 15 years and analyse the clinical and morphological factors related to DTC.Methods: We reviewed the series of patients undergoing thyroid surgery at our hospital over a 15-year period and identified patients with DTC. Patients were divid...

Background: Most thyroid specific genes are transcriptionally regulated by TSH-TSHR signalling and T4-driven negative feedback of TSH secretion at the pituitary. However, local autoregulation of transcription has been described from IGF-IGFR, follicular thyroglobulin, or iodine. We aimed to investigate the TSH dependency of thyroid transcriptional regulation in the Dehal1 knockout, devoid of iodide-recycling capacity from iodotyrosines.Methods: ...

Background: Pancreatic Cancer (PC) is uncommon; however, it is one of the most deadly cancer types of all. New-onset diabetes (NOD) is associated with a higher risk of pancreatic cancer than general population, particularly if late-onset. An association between new-onset diabetes and increased mortality in patients with pancreatic cancer has been suggested but clinical relevant differences between those individuals with new-onset diabetes and those without are not well establi...
