Aim: To evaluate the prevalence and incidence of type 2 diabetes in patients with nonfunctioning adrenal incidentalomas (NFAI) and autonomous cortisol secretion (ACS) coming from a cohort of adrenal incidentalomas consecutively evaluated in a tertiary hospital in a predefined period (2013-2020).Methods: In this retrospective study, adrenal incidentalomas ≥1cm with ACS and NFAI were included. ACS was defined by a post-dexamethasone suppression test ...

Molecular mechanisms involved in lactotrophs cell proliferation that led to prolactinoma development are not fully understood. Cyclin-dependant kinase (CDK) p27Kip1 is a key cell cycle regulator, and it is regulated by Menin. The transgenic mice model MEN1+/-, as the p27 -/- knock-out mice, develop pituitary adenomas and other neuroendocrine tumours. Menin can also interfere with phosphorylated AKT (pAKT) function, known for i...

Introduction: Hyponatremia is the most frequent electrolyte disorder in hospitalised patients. Our aim was to determine the incidence, mean hospital stay, readmission rate and mortality rate among patients with acute heart failure (HF) and hyponatremia.Methods: Retrospective analysis of data collected from the minimum data set (MDS) of Spanish National health System during 2005–2012 from discharged patients of Internal Medicine with HF and hyponatre...

Introduction: Obesity is a chronic condition with great morbidity, mortality and significant economic and psychosocial impact. Bariatric surgery has proven to be an effective therapy for sustained weight loss and has allowed a reduction in medical comorbidity and an improvement in self-esteem and life quality. However, recent evidence reports an increase in eating and substance-related disorders that are diagnosed in the postoperative period worsening the prognosis.<p clas...

Background: Evidence has shown that the use of high doses of statins is associated with lower levels of LDL cholesterol and a decrease in cardiovascular events. Likewise, the use of high doses of statins may increase the risk of myopathy, elevation of liver enzymes, renal failure and cognitive alterations. We conducted a systematic review with a meta-analysis of all RCTs investigating the impact of atorvastatin and ezetimibe therapy on levels of LDL cholesterol vs high doses o...

It is known that the synthesis and release of pituitary GH is controlled by complex neuroendocrine mechanisms that involve several neuropeptides, such as GHRH, SST, PACAP, TRH, GnRH, Ghrelin, among other regulators. Previous reports indicate that, during vertebrate evolution, the potency and efficacy of these secretagogues may vary and play differential effects upon GH regulation. In this work we aimed to study, in vitro, the capacity of these peptides to control the ...

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: ...

Background: The goals of acromegaly treatment are to achieve long-term biochemical control, control tumor size and decrease the risk of developing systemic comorbidities. Moreover, from the patient’s perspective, symptoms and QoL are critical parameters of disease control and should be assessed routinely. To aid in the global clinical management of acromegaly, a holistic clinical decision support tool, the Acromegaly Disease Activity Tool (ACRODAT®) was developed.</p...

Introduction: Maturity onset diabetes mellitus of the young (MODY) is a form of monogenic diabetes characterized by pancreatic B-cell dysfunction. The most common subtypes are caused by mutations in the genes encoding glucokinase (GCK) and hepatocyte nuclear factor (HNF1a, HNF4a), although unidentified genes are also involved. Regulatory factor X6 (RFX6) is a transcription factor gene which has an important biological role in B-cell formation and function. Biallelic mutations ...

Background: Islet transplantation is an established treatment for type 1 diabetes mellitus. However, many recipients do not achieve independence from exogenous insulin since up to 50–70% of islets are lost post-transplant. An important factor determining transplant success is graft vascularisation. The epidermal growth factor receptor (EGFR) is a key pro-survival and proliferation factor. Here, we investigate for the first time if EGFR overexpression in pancreatic islets ...
