Objectives: Image-guided thermal-ablation (LTA; RFA) are well established therapy options in selected BTN. PMWT is a mini-invasive technique recently applied in thyroid disease; aim of this work is investigate its effectiveness as treatment in BTN.Methods: From May 2021, 45 patients (30 F, 15 M, Aged 37-90, Mean 55,8) with BTN symptomatic/in growing, refusing/non eligible to surgery were enrolled. Inclusion criteria: nodule diameter ≥ 2 cm, mainly ...

Background: Calcifediol (25(OH)D3), the major circulating form and the direct precursor of the biologically active form of vitamin D, has been identified as an agonist ligand for vitamin D receptor (VDR) with anti-proliferative effects and gene regulatory function despite having a lower receptor affinity respect than the biologically active form of vitamin D3. In fact, recent studies have suggested that 25(OH)D3 can regulate gene expression by ...

Background: Multiple endocrine neoplasia of type 1 (MEN1) is a rare heritable endocrine tumor syndrome that results from biallelic inactivation of the MEN1 gene and the loss of menin protein, that was characterized by a susceptibility to the development of multiple endocrine neoplasms within a single patient. The MEN1 gene screening is helpful in the clinical practice for early genetic diagnosis. Unfortunately, the lack of genotype-phenotype correlation doesn’t allow to f...

Objective: Thermal ablations (TA) are gaining ground as alternative options to conventional therapies for symptomatic benign thyroid nodules. Little is known on the impact of nodule biology on the outcomes of TA. The aim of our study was evaluating the baseline immunocytochemistry profile of thyroid nodules that are poorly responsive to TA, in order to identify potential predictors of treatment response.Methods: we retrospectively selected by propensity ...

Monogenic diabetes is estimated to account for 1-2% of all diabetes cases diagnosed before the age of 45. It is caused by mutations in genes encoding for beta cell development, function and regulation. We present three cases of monogenic diabetes in pregnancy.Case 1: Age 30, Para 3, White ethnicity. This individual was screened for a GCK mutation at 18 weeks gestation (third pregnancy) on the basis of family history. She required metformin and insulin to...

Background: Alstrom syndrome (AS; OMIM#203800) is a rare (<1:100.000) autosomal recessive monogenic ciliopathy and it is caused by mutations in ALMS1 (chromosome 2p13), which function is still unknown. AS is characterized by multisystemic fibrosis, cone-rod retinal dystrophy leading to blindness, hearing loss, obesity, type 2 diabetes mellitus (T2DM), dilated cardiomyopathy, and progressive hepatic and renal failure. Most patients present neurological issue on developmenta...

In the framework of close interactions between the immune and neuroendocrine systems, Growth Hormone (GH) has been proposed to exert significant effects on the immune system, but there is not yet a consensus about GH immunomodulatory properties. These studies investigated the immune and anti-infectious response of dwarf Ghrh−/− mice presenting a severe deficiency of the GHRH/GH/IGF-1 axis. In basal conditions, thymic parameters and T-cell respon...

Aims/objectives: Obesity and prediabetes are risk factors for developing T2D. 5–10% weight-loss can reduce risk of developing T2D by >50%. The 3-year part of this phase 3 trial investigated effects of liraglutide 3.0 mg, as adjunct to diet+exercise, in delaying onset of T2D over 3 years, body-weight and cardiometabolic risk factors in adults with obesity or overweight with comorbidities, and diagnosed with prediabetes at screening.Methods: Indiv...

Growth hormone deficiency (GHD) has become increasingly recognized as a cause of metabolic syndrome, characterized by altered body composition and adverse cardiovascular risk. The effects of other pituitary hormone deficiencies or their replacement therapies on the metabolic profile in this clinical setting are still largely unclear. In this study, we aimed to evaluating the effects of replacement therapies of central hypoadrenalism and hypothyroidism on body composition in a ...

Background: Endothelial dysfunction leads to cardiovascular complications in type 2 diabetes mellitus (T2DM), through a reduction of nitric oxide (NO)-mediated relaxation. Phosphodiesterase-5 inhibitors (PDE5i) have hemodynamic effects, improving NO levels.Aim: To investigate if long term, chronic treatment with the PDE5i Vardenafil improves systemic endothelial function in men with T2DM.Methods: A longitudinal, prospective, invest...
