    Pregnant Greek Women May Have a Higher Prevalence of Iodine Deficiency than the General Greek Population.
    Eur Thyroid J 2017 Feb 28;6(1):26-30. Epub 2016 Sep 28.
    Division of Endocrinology, University Medical School, University Hospital, Rion-Patras, Greece.
    Background: Adequate dietary iodine consumption, predicted via the urinary iodine concentration (UIC), is necessary for normal thyroid function and for the neurodevelopment of fetuses and neonates. The general population of Greece is considered to be iodine sufficient, but our preliminary findings suggest that Greek pregnant women are at risk of iodine deficiency.

    Objective: Our aim was to estimate the thyroid function and UIC in a representative population of pregnant Greek women. Read More

    In 1994 international organizations: WHO,UNICEF and ICCIDD indicated salt - Natrium Chloride as a main carrier of iodine in the prophilaxis systems in the iodine deficient areas over the world. Following this recommendation 24 European countries introduced the model of iodine prophylaxis based on the salt iodization. However in 7 European countries only - among them in Poland - salt iodization is mandatory -as the most effective model on the population level. Read More

    Thyroglobulin level at week 16 of pregnancy is superior to urinary iodine concentration in revealing preconceptual and first trimester iodine supply.

    Division of Endocrinology, Department of Medicine, Faculty of Medicine, University of Debrecen, Debrecen, Hungary.
    Pregnant women are prone to iodine deficiency due to the increased need for iodine during gestation. Progress has recently occurred in establishing serum thyroglobulin (Tg) as an iodine status biomarker, but there is no accepted reference range for iodine sufficiency during pregnancy. An observational study was conducted in 164 pregnant women. Read More

    Consumption of Fish Is Not Associated with Risk of Differentiated Thyroid Carcinoma in the European Prospective Investigation into Cancer and Nutrition (EPIC) Study.
