Subacute THYROiditis Related to SARS-CoV-2 VAccine and Covid-19 (THYROVAC Study): A Multicenter Nationwide Study.

Context: The aims of the study are to compare characteristics of subacute thyroiditis (SAT) related to different etiologies, and to identify predictors of recurrence of SAT and incident hypothyroidism.

Methods: This nationwide, multicenter, retrospective cohort study included 53 endocrinology centers in Turkey. The study participants were divided into either COVID-19-related SAT (Cov-SAT), SARS-CoV-2 vaccine-related SAT (Vac-SAT), or control SAT (Cont-SAT) groups.

Iodine status of pregnant women in iodine-sufficient regions: A tertiary care unit experience.

Background: The recommended urinary iodine concentration (UIC) levels in the overall adult population is 100-199 μg/L whereas 150-249 μg/L in pregnant women.

Objectives: The objective is to determine the prevalence and severity of iodine deficiency in pregnant women in Amasya, which is located in the Western Black Sea region in Turkey, where sufficient iodine levels were achieved in the normal population.

Methods: In this single-center study, we retrospectively searched hospital patient records and identified pregnant women who were assessed for iodine levels between January 2019 and January 2021.

Factors affecting recurrence in subacute granulomatous thyroiditis.

Objective: This study aimed to evaluate the factors affecting recurrence in subacute granulomatous thyroiditis (SAT).

Methods: A total of 137 patients with SAT were enrolled in the study; 98 (71.5%) were women and 39 (28.

Identifying Clinical Characteristics of Hypoparathyroidism in Turkey: HIPOPARATURK-NET Study.

Hypoparathyroidism is an orphan disease with ill-defined epidemiology that is subject to geographic variability. We conducted this study to assess the demographics, etiologic distribution, treatment patterns and complication frequency of patients with chronic hypoparathyroidism in Turkey. This is a retrospective, cross-sectional database study, with collaboration of 30 endocrinology centers located in 20 cities across seven geographical regions of Turkey.

Free triiodothyronine to free thyroxine ratio in the differential diagnosis of thyrotoxicosis and hyperthyroidism: A retrospective study.

Background: Thyroid ultrasound, thyroid scintigraphy and radioactive iodine uptake (RAIU) tests are helpful in the differential diagnosis of thyrotoxicosis and hyperthyroidism. In the setting where these techniques are unavailable or unusable more accessible, and cheaper techniques would be helpful.

Aims: We evaluated the capability of free triiodothyronine to free thyroxine ratio (FT3/FT4) to differentiate Graves' Disease (GD) and destructive thyroiditis (DT).
