There is an accumulating amount of evidence that the metabolic adaptations to endurance exercise that result in increased intramuscular triglyceride (IMTG) stores and IMTG oxidation during exercise, also exert a protective effect on muscle insulin sensitivity. This seems to be a contradiction (known as the athlete's paradox) as large IMTG stores in sedentary and obese individuals coexist with high levels of fatty acid (FA) metabolites (specifically long-chain acylCoA, DAG and ...

We know that non-severe hypoglycaemia (SH) should be treated with the immediate intake of 15–20 g of oral glucose, there are no data according to our knowledge in the current literature for the dose of glucose that is necessary to inject in SH. We have analysed retrospectively the treatment of pre hospital SHs as reported after an emergency call for intervention. Our primary objective was to know the dose of the given glucose and our secondary objective was to know the fa...

Evidence has accumulated about the involvement of the CRF system in the regulation of energy balance. The effects of CRF are mediated by two receptors: CRFR1 and CRFR2. The role of the CRFR1 in the regulation of energy balance is not well defined. To address this issue, adult male CRFR1 KO mice and WT littermates were given low fat (LFD) or high-fat (HFD) diets for 4 months. Under LFD no differences between genotypes were seen on body weight (BW) and caloric intake. KO mice ha...

Background: Medullary thyroid carcinoma (MTC) is a neuroendocrine tumor derived from the parafollicular C-cells of the thyroid gland. Mutations in the gene encoding the Rearranged during Transfection (RET) tyrosine kinase, play a vital role in the development of MTCs. In patients with distant metastases, only targeted therapy can prolong survival. Tyrosine kinase inhibitors (TKIs) block tyrosine kinases such as RET and thereby inhibit tumor proliferation. However, it is diffic...

Background: Primary hyperparathyroidism (pHPT) is a common disease in a routine endocrinology praxis, but the biggest challenge is a localization of the adenoma and the further correct management of the disease. First FCPCT was reported in 2014 as the additional method of diagnosis of pHPT and in some centers has been already used as a first line diagnostic modality. However, FCPCT is still lacking in the European or International guidelines for the diagnosis of pHPT.<p cl...

Rationale: The Aldosterone:Renin ratio (ARR) is commonly used for patients fulfilling screening criteria for primary hyperaldosteronism (PA), followed by confirmatory testing. Reference intervals for interpretation of the ARR vary in accordance with local population and assay 1. While ARR provides high sensitivity for PA, this is compromised by low specificity, further compounded by medication interference. However, additional variables may improve the specificity of ARR as a ...

Background: The 3-year part of this trial investigated the effect of liraglutide 3.0 mg, as an adjunct to diet+exercise, in delaying onset of T2D (primary endpoint) in adults with prediabetes and obesity (BMI ≥30 kg/m2) or overweight (≥27 kg/m2) with comorbidities.Methods: Participants were randomised 2:1 to once-daily subcutaneous liraglutide 3.0 mg or placebo plus 500 kcal/day deficit diet and 150...

Introduction: Dysregulation of glucocorticoid (GC) metabolism is implicated in the pathogenesis of non-alcoholic fatty liver disease (NAFLD). The only available treatment for NAFLD is weight loss and the gold standard diagnostic test is liver biopsy, which is invasive and resource intensive. NAFLD ranges from simple steatosis, to inflammation (steatohepatitis/NASH), fibrosis and cirrhosis. It may be regarded as the hepatic manifestation of the metabolic syndrome and is strongl...

Introduction: Dysregulated glucocorticoid (GC) metabolism has been implicated in the pathogenesis of non-alcoholic fatty liver disease (NAFLD). NAFLD extends from simple steatosis, to inflammation (steatohepatitis/NASH), fibrosis and consequent cirrhosis. It is often regarded as the hepatic manifestation of the metabolic syndrome and is independently associated with increased liver and cardiovascular mortality. Changes in GC metabolism have thus far been described in small num...
