To analyse in a cohort of healthy subjects and in a group of morbidly obese patients, we studied the association amongst 25(OH) D and plasma concentrations of adipocytokines, inflammatory cytokines and insulin resistance. We also aimed to determine whether vitamin D-deficient patients showed a greater inflammatory profile. In the observational study that the authors conducted, plasma concentrations...
Small cell carcinomas may occur in the thyroid gland. Infrequently, they are primary tumors, and have been interpreted as variants of medullary thyroid carcinoma.

An example of a small cell carcinoma metastatic to the thyroid is presented...
The aim of this study was to investigate the GH-IGF-I axis in healthy adults and its relationship to obesity. We studied 268 subjects: 134 men and 134 women, and determined anthropometric and body composition variables. Serum total IGF-I was measured by radioimmunoassay, serum free IGF-I concentrations by enzyme linked immunosorbant assay and serum IGFBP3 concentrations by radioimmunoassay. In men,...
