Introduction: Brain-derived neurotrophic factor (BDNF) is a protein that has been linked to several cardiovascular risk factors and bone status. Stress and corticosteroid exposure can affect BDNF levels, although this has never been studied in Cushing’s syndrome (CS). The aims of this study were to establish if BDNF levels were reduced in CS and to check possible associations to cardiovascular risk factors and bone status.Methods: 52 patients (18 ac...

Background: Pregnancy may adversely affect the progression of diabetic retinopathy and can have serious implications for the pregnant women.Aim: To asses the impact of pregnancy on the progression of diabetic retinopathy in women with type 1 and type 2 diabetes mellitus and to identify risk factors for the progression of retinopathy during pregnancy.Methods: 306 diabetic women, 229 (75.4%) with type 1 and 77 (23.9%) with type 2 di...

Introduction: Paragangliomas/pheochromocytomas present frequently with vague symptomatology which makes its diagnosis difficult and challenging. Cuantification of fractionated metanephrines and fractionated catecholamines in 24 h urine sample are used for diagnosis. There are situationes that can produce false positive results such as stress, drugs or smoking that must be taken into account.Patients and methods: Retrospective study on the requests made f...

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...

Introduction: Vitamin D deficiency and insufficiency is highly prevalent even in young people. Vitamin D status has been linked to the BMI and insulin resistance.Aim: Determine 25(OH)D concentrations in adolescents before and after nutritional intervention program (NIP) and its relationship to BMI and metabolic syndrome (MS).Methods: We selected 256 secondary school students (127 males) aged between 12 and 16 years from Granada (Sp...

Background: Previous studies have suggested that serum thyroglobulin (Tg) levels at the time of 131I remnant ablation just after thyroidectomy, could be a prognostic tumor marker in differentiated thyroid cancer (DTC).Objective: The aim of this study was to evaluate if serum preablation Tg in the earliest postoperative period could be useful for predicting persistence or recurrence of disease.Methods: This study was a retrospective...

Background: The most common type of thyroid cancer is the well-differentiated thyroid carcinoma (DTC) and that includes papillary (PTC) and follicular carcinoma (FTC). The PTC would represent 50–90% and the FTC over 15–30%. Within the PTC, the most frequent is the classical variant (over 80%), followed by follicular variant (10%) and the rest of variants (<10%). Furthermore, there are differences between PTC and FTC in age at diagnosis, local extension, multicent...

Quality of life is impaired in patients who have suffered Cushing’s syndrome (CS).Aim: Evaluate QoL with the new questionnaire CushingQoL in Spanish patients in a clinical practice setting and compare it with a generic QoL questionnaire, EuroQoL-5 Dimensions (5D) and its Visual Analogue Scale (VAS).Patients and methods: Forty-three patients with CS (38 pituitary-dependent, 28 cured) were approached during their regular endocri...

The Hypoparathyroidism Symptom Diary (HypoPT-SD) was developed for the daily assessment of key symptoms and impact of HypoPT as reported by patients with chronic HypoPT and includes 13-items: a 7-item Symptom subscale, 4-item Impact subscale, and single-item anxiety and depression scores. The current analysis was undertaken to confirm test-retest reliability and construct validity of HypoPT SD Symptom subscale scores using data collected during two open-label, single-arm studi...

Androgen signalling plays a central role in the regulation of male reproduction. Androgens act predominantly by activating the classical intracellular androgen receptor (AR). In addition, alternative pathways may account for rapid effects of androgens via cytoplasmic or membrane-localized androgen receptor − ZIP9. In the testis, the main source of androgens, in particular testosterone, are Leydig cells. The proper synthesis of testosterone depends on the structural condi...
