Introduction: The association of fasting glucose (FG) in early pregnancy (EP) with adverse outcomes for the mother and her offspring is well known, although the best cut-offs for diagnosis of Gestational Diabetes (GD) are not consensual.Objetive: Evaluate the impact of FG in EP in the management of pregnant women and obstetric and fetal outcomes.Methods: Retrospective cohort of pregnant women with GD diagnosed before 24 weeks of ge...

Introduction: Due to the growing prevalence of obesity, more women are overweight in early pregnancy, leading to adverse neonatal and obstetric outcomes.Objective: To evaluate the influence of maternal prepregnancy body mass index (BMI) on blood glucose levels at diagnosis of gestational diabetes (GD), obstetric and neonatal outcomes.Methods: Retrospective observational study including women with GD and singleton pregnancy, with fo...

Introduction: Abnormal glucose metabolism (AGM) is the most common extra-pulmonary comorbidity in people with cystic fibrosis (CF) and has a high negative impact on the underlying disease. Elevated postprandial glucose level is usually the first manifestation, which is traditionally detected by 75-gram oral glucose tolerance test (OGTT). The aim of this study was to evaluate glycemic pattern during continuous glucose monitoring (CGM) in patients with impaired glucose metabolis...

Introduction: The American Diabetes Association guideline states that the long-term use of metformin may be associated with biochemical vitamin B12 (B12) deficiency and periodic measurement should be considered, although isolated serum B12 measurement has low sensitivity and specificity. Homocysteine (Hcy) and methylmalonic acid (MMA) are more sensitive biomarkers, the latter being more specific.Objectives: To estimate B12 deficiency in type 2 diabetics ...

Introduction: Non-functioning pituitary adenomas are relatively common. A large number of these tumors are asintomathic pituitary microadenomas, that are increasingly detected because of sensitive imaging techniques improves. Those tumors that require treatment are generally macroadenomas and come to medical attention because of mass effect (visual field defects, headache, …) and/or hypopituitarism.Objective: To assess non-functioning pituitary ade...

Introduction: Diamond-Blackfan anemia (DBA) is a severe congenital erythroid aplastic anemia with autosomal dominant inheritance. It is a rare disease (incidence 1/150000) and usually is discovered during the 2 first years after birth. Treatment includes steroids, blood transfusions and bone-marrow transplantation.Case report: A 31 year-old woman with DBA had received multiple treatments including transfusion support since birth. Consequently, she had de...

Introduction: Pituitary adenomas are considered to be benign tumors that are diagnosed by its sympthoms (secondary to compression or hormonal secretion) or incidentally in an imaging technique performed because of another reason. ‘Silent’ somatotrophinomas are very rare. This type of adenoma is typically large and despite it presents with mild or no acromegalic features it usually develops hormone secretion.A case report: A 29-year-old spanish ...

Primary aldosteronism is the most common form of secondary hypertension. Somatic mutations in KCNJ5, ATP1A1, ATP2B3 and CACNA1D have been described in 50% of aldosterone producing adenomas (APA). To identify genetic alterations in new genes, we performed whole exome sequencing in 23 patients with APA negative for recurrent mutations in known driver genes. A low number of somatic variations were identified per patient, ranging from 1 to 22. N...

Introduction and Objectives: The incidence of thyroid cancer has increased worldwide. This increase has been attributed to more diagnosed papillary thyroid microcarcinomas. The purpose of this study was to analyse the growing trend of first appointments in our Thyroid Cancer Unit, namely patients with papillary microcarcinomas.Methods: We performed a retrospective study based on the patients diagnosed with thyroid cancer between 1960 and 2016. We divided...

The cAMP signaling pathway plays a major role in the pathogenesis of cortisol-producing adrenocortical adenomas (CPA). In adrenocortical cells cAMP induces dramatic changes in cell morphology accompanied by actin cytoskeleton rearrangements that precede steroidogenesis, the causal relationship between these events being still undefined. In this study we investigated cAMP effects on cytoskeleton rearrangements and steroidogenic response in mouse (Y1) and human adrenocortical tu...
