Purpose: The aim of this study was to evaluate the hemodynamic status of the thyroid in children with goiter after the use of iodinated dietary salt for 3 years in a region of endemic iodine deficiency.
Methods: Sixty-six children between 7 and 12 years of age were included in the study. Three groups were constituted according to sonographically measured thyroid volume and urinary iodine excretion levels. Group 1 included 11 children with thyroid volumes greater than the 97th percentile according to age and sex criteria suggested by the World Health Organization International Council for Control of Iodine Deficiency Disorders and urinary iodine level lower than 100 microg/l. Group 2 included 30 children with thyroid volumes greater than the 97th percentile and urinary iodine level equal to or higher than 100 microg/l. The control group included 25 children who had normal thyroid volume and urinary iodine level. All children were examined by thyroid duplex sonography. Peak systolic velocity (PSV) and resistance index (RI) were measured in the inferior thyroid artery bilaterally.
Results: PSV in group 1 was significantly higher than in group 2 and in the control group (P < 0.05 and P < 0.01, respectively). There was no significant difference between the PSV of group 2 and the control group. The RI in groups 1 and 2 was significantly lower than in the control group (P < 0.01 and P < 0.01, respectively). There was no significant difference between the RIs of group 1 and group 2.
Conclusions: These findings suggest an effect of iodination on thyroid hemodynamics before the size of the hyperplastic thyroid returned to normal, in keeping with normalization of the urinary iodine level.

Contrast-induced acute kidney injury is a common complication marked by reduced kidney function within 48 hours of contrast administration. The aim of this study was to evaluate renal function, anatomy, and molecular changes at 24 hours, 48 hours, and 72 hours post-iodinated contrast media (ICM) administration. This true-experimental study used a post-test-only control group design.

Background: Technological advancements and globalization have shifted dietary behaviours, contributing to increased chronic disease prevalence in Low- and Middle-Income Countries (LMICs) like India. Adolescents are particularly vulnerable due to these changes, which can impact their lifelong health. This study aimed to assess the nutritional status of adolescents in public schools in Chandigarh, India.

Objective: To assess whether individual diagnosis of low urinary iodine concentration (UIC) in pregnant women is associated with adverse maternal and neonatal outcomes.
Methods: Studies that compared pregnant women with UIC <150 μg/L and those with UIC 150-249 μg/L were systematically reviewed. MEDLINE, EMBASE, LILACS, and CENTRAL were our source databases.
