Calcitonin Screening in Nodular Thyroid Disease: Is There a Definitive Answer?

Introduction: Calcitonin (Ctn) is a hormone secreted by thyroid "C" cells and is considered an excellent marker for medullary thyroid carcinoma (MTC). However, the use of Ctn to screen patients with nodular thyroid disease (NTD) remains controversial.

Objective: The aim of this work was to define the frequency of hypercalcitoninemia among NTD patients followed at a tertiary referral hospital.

Influence of body mass index in anti-Müllerian hormone levels in 951 non-polycystic ovarian syndrome women followed at a reproductive medicine unit.

Purpose: Anti-Müllerian hormone (AMH) is a useful marker of ovarian reserve. Obesity/overweight are increasing and may affect the reproductive health. Previous studies regarding the effect of body mass index (BMI) on AMH levels are discordant.

N-terminal probrain natriuretic peptide as a biomarker of cardioembolic stroke.

Background: and purpose N-terminal probrain natriuretic peptide, which is mainly produced by the heart, is increased in acute stroke. We aimed to determine if N-terminal probrain natriuretic peptide could be a biomarker for ischemic stroke with a cardioembolic cause.

Methods: Consecutive sample of acute stroke patients admitted to a Stroke Unit.
