Introduction: In patients with type 1 diabetes, exercise has not consistently been shown to improve glycemic control, as measured using HbA1c levels. Participation in competitive sports may even worsen glycaemic control. Free radicals and oxidative stress markers are known to increase during acute exercise in parallel to decreased circulating antioxidant concentrations. We aimed to analyze the effects of chronic and acute exercise on circulating HbA1c and fructosamine levels.<...

Introduction: The aim of our study was to evaluate the causes of thyrotoxicosis detected during pregnancy as well as to determine the prevalence of thyroid nodular disease (TND) in our population and which factors are associated with this condition.Methods: We performed a retrospective review of 1,760 patients between April 2014 and September 2017 remitted from the gynecology department due to thyroid dysfunction detected in the 9th week of pr...

Introduction: An increased risk of thyroid disease (TD) has been described in patients with type 1 diabetes (DM1) with respect to the general population. The objective is to establish the incidence and characterize the differences in patients who develop TD in relation to the debut of DM1 (previous, concurrent or a posteriori).Materials and methods: Retrospective study of 1126 patients followed up in Endocrinology consultations in Navarra. Three types of...

Women with positive thyroid autoimmunity are considered at risk of developing hypothyroidism in pregnancy, so monitoring thyroid function is recommended.Objective: To assess the risk of gestational hypothyroidism in pregnant women with autoimmune thyroid disease and normal thyrotropin (TSH) at the beginning of pregnancy.Methods: Retrospective review of data from pregnant women attended between April 2016 and October 2019. Women wit...

Introduction: Hypothyroidism during pregnancy has been asociated with adverse maternal and neonatal outcomes. During pregnancy, maternal levothyroxine (LT4) dose requirements increase. The aim of this study is to determine the increase of LT4 doses during pregnancy in pregestational hypothyroid women.Methods: We included 76 hypothyroid pregnant women. We analyzed analytical and clinical characteristics of these patients, as well as the increase of LT4 re...
