Deep Phenotyping of Peripheral Blood Cells and Circulating Factors in Metabolic Diseases

The goal of this cross-sectional observational study is to to perform a thorough characterization of the quantitative and qualitative differences in peripheral blood cells, and circulating factors (proteins, metabolites, lipids, extracellular vesicles) in different stages of several metabolic diseases (diabetes, obesity, non-alcoholic fatty liver disease) that share common pathophysiological mechanisms and in comparison with adult healthy controls. The main question\[s\] it aims to answer are: * Which are the quantitative (number and concentration) and qualtitative (characteristics, functional assays) differences in platelets in patients with metabolic diseases vs subjects without metabolic diseases * Which are the quantitative (number and concentration) and qualtitative (characteristics, functional assays) differences in leucocytes or circulating molecules in patients with metabolic diseases vs subjects without metabolic diseases
