Introduction: Immune tumor microenvironment plays a key role in tumors’ growth and metastatic spread, while its role in the heterogeneous field of neuroendocrine neoplasms (NENs) remains unclear. There is evidence that tumor progression in NENs is promoted by an immunosuppressed microenvironment created by a plethora of infiltrating immune cells. Changes in circulating leukocyte and peripheral blood mononuclear cell (PBMC) subpopulations can mirror the local alteration of...

Introduction: Low-grade incomplete post-dexamethasone cortisol suppression in patients with adrenal incidentalomas, recently redefined as possible autonomous cortisol secretion (pACS), has been associated with increased cardiovascular events and mortality. However, prospective studies documenting cardiac abnormalities in these patients are lacking.Methods: In the context of ERGO trial NIH (NCT02611258), between July 2016 and September 2017, 71 consecutiv...

Introduction: Adrenal insufficiency requires life-long glucocorticoid replacement. Conventional therapies fail to mimic endogenous cortisol circadian rhythm. Clock genes are essential components of the molecular machinery controlling organ’s circadian function and are influenced by glucocorticoids. However, clock genes expression has never been investigated in patients with adrenal insufficiency (AI).Aim: To evaluate the effect of the timing of gluc...

Background: Cyclic GMP-phosphodiesterase type 5(PDE5) inhibition was shown to counteract maladaptive cardiac changes triggered by diabetes in some, but not all studies.Objective: To assess sex differences in cardiac remodeling after PDE5 inhibition in patients with diabetic cardiomyopathy.Methods: 20-week, double-blind, randomized, placebo-controlled trial (NCT01803828). 220 men and women (45-80 years) with long-duration (>3 ye...
