Background and objectives: The finding of a thyroid nodule is a very common occurrence in clinical practice. Management of thyroid nodules requires a multidisciplinary approach that may be eased by a high-resolution thyroid nodule clinic. We report our clinical experience and outcomes in a high-resolution thyroid nodule clinic.Patients and methods: All patients referred to Virgen de la Victoria Hospital (Málaga) from 2005 to 2007 were evaluated foll...

Up to now there are few studies about differential proteomics in thyroid. Our group has developed a method for standard human primary thyroid culture maintaining the phenotype through passages. Thus, we believe of great interest the search for biomarkers in these cultures by 2D-PAGE coupled to MALDI-TOF/TOF-MS.Aims: i) To standardize the conditions for sample extraction and controls. ii) To compare and identify the differential proteomic pattern between ...

Background: CLDN14 gene encodes a protein involved in regulation of paracellular permeability or ion transport at epithelial tight junctions as in the nephron. C allele of the rs219780 SNP of CLDN14 gene has been associated with high levels of PTH and with low bone mineral density (BMD) in women. Our aim is to study the relationship between rs219780 SNP of CLDN14 and fractures, renal lithiasis and bone mineral density in patients with primary hyperparathyr...

Objectives: Our aim is to assess the cardiovascular risk factors that are already present at the time of diagnosing new-onset type 2 diabetes mellitus (DM).Materials and methods: This was an observational study. From each patient the following data were retrospective collected between January 2008 and September 2009: age, sex, DM in the family, smoking, HbA1c, hypertension (HTA) and dyslipidemia, microangiopathy and macroangiopathy, lipids and medical tr...

Introduction: Pituitary adenomas are the most common cause of sellar masses from the third decade on, accounting for up to 10 percent of all intracraneal neoplasms.Objective: To review pituitary adenomas diagnosed in Burgos.Patients and methods: It was a retrospective study in which we reviewed a total of 90 pituitary adenomas detected in Burgos from 1983 to our days.Results: About 65% were macroadenomas and ...

Nowadays, though highly improved, the efficiency of human assisted reproduction protocols remains affected by a decrease in embryo yields after IVF. The aim of the current study was to evaluate a possible relationship between poor embryos and the functionality of follicles stimulated to grow with exogenous gonadotrophins, using a monovular species (sheep) as a model. In ewes, follicles can ovulate from ≥6 mm in unstimulated cycles, but from ≥4 mm in FSH treatments....

Introduction: Gestational diabetes mellitus (GDM) is associated with an increase of maternal-fetal complications. Continuous glucose monitoring system (CGMS) detects parameters of glycemic variability through which it could be predicted the appearance of maternal-fetal complications.Methods: Women with GDM at 26–32 gestational weeks were allocated a 6-day CGM system (IproTM2) right after diagnosis in an observational prospective study. It...

Introduction: Gestational diabetes mellitus (GDM) is associated with an increase of maternal-fetal complications. Continuous glucose monitoring system (CGMS) detects postprandial hyperglycemia and hypoglycemia during 24h.Methods: Women with GDM in gestational weeks 26–32 were allocated a CGMS (IproTM2) after diagnosis in an observational prospective study. It was analysed: Mean glucose and standard deviation, area under the curve (AUC) wi...

Introduction: Diabetes mellitus is associated with an increased risk of osteoporotic fractures, which leads to an increased risk of disability and frailty.Aims: To assess the prevalence of frailty in type 2 diabetes and to analyze the relationship with bone mineral density (BMD) and Trabecular Bone Score (TBS), fracture risk and prevalent fractures.Methods: We carried out a cross-sectional study of 75 diabetic patients (65±7 y...

Background: Metformin is one of the first line drugs used to treat type 2 diabetes mellitus, even though there are still many gaps on how exactly metformin works. This is due to many years of research using various concentrations of metformin and also, not considering the conditional effect that glucose can have in its action.Objectives: Study the effect of different concentrations of metformin and glucose in cell culture.Methods: ...
