Objective: The determination of (a) iodine deficiency, and (b) the relation between the iodized salt consumption in the Isparta province of Turkey.
Methods: Five hundred students between 6-11 yr of age were evaluated. With a questionnaire, the subjects were asked whether they were using iodine-containing salt or not. After their body weight and height were measured, thyroid glands were examined with palpation, thyroid volumes were determined with ultrasonography (USG), and urinary iodine concentration was analyzed.
Results: The median urinary iodine concentration (UIC) of children was 7.00 microg/dl. This value reveals that Isparta is a region with mild iodine deficiency. The total goiter prevalence was 30.4% with palpation and 26% with USG. The goiter prevalence by ultrasonography was 14.2% for the urban and 36.2% for the rural areas. This difference was statistically significant (p<0.05). The rate of total iodized salt consumption was 68%, which was not a satisfactory level. The consumption of iodized salt in the urban areas was significantly higher than that in rural areas (74 vs 62%, p<0.05). The median UIC value was 10.00 microg/dl in urban areas compared to 5.00 microg/dl in rural areas.
Conclusions: Our results indicate that although Isparta is a region with mild iodine deficiency, goiter prevalence remains a serious problem.

Evaluation of dietary quality in patients with functional gastrointestinal symptoms: a Norwegian single centre study.

Background: Poor dietary quality has been described as a contributor to symptoms in subjects with functional gastrointestinal (GI) symptoms. Hitherto, the focus in dietary evaluation and treatment in this patient group has mainly been on avoiding individual nutrient deficiencies, and less attention has been given to the dietary pattern and the overall food quality. Hence, we aim to describe and evaluate the dietary quality in patients with functional GI symptoms.

The multielectron conversion electrochemistry of I/I/I enables high specific capacity and voltage in zinc-iodine batteries. Unfortunately, the I ions are thermodynamically unstable and are highly susceptible to hydrolysis. Current endeavors primarily focus on exploring interhalogen chemistry to activate the I/I couple.

Thyroid hormones (THs) require iodine for biosynthesis and play critical roles in brain development. Perchlorate is an environmental contaminant that reduces serum THs by blocking the uptake of iodine from the blood to the thyroid gland. Using a pregnant rodent model, we examined the impact of maternal exposure to perchlorate under conditions of dietary iodine deficiency (ID) on the brain and behavior of offspring.

Universal salt iodisation (USI) plays an essential role in the provision of iodine (I) to populations worldwide. Countries adopting USI programmes, adhering to strict criteria laid down by expert organisations such as the Iodine Global Network, are estimated to have reduced the prevalence of I deficiency by 75% (protecting 720 million individuals worldwide). Despite this success, doubts have been raised as to the desirability of continuing such programmes because of (a) the need to reduce salt intake for cardiovascular prevention and (b) the induction of thyroid autoimmunity.

An increasing number of studies highlight the critical role of both maternal and paternal nutrition and body weight before conception in shaping offspring health. Traditionally, research has focused on maternal factors, particularly in utero exposures, as key determinants of chronic disease development. However, emerging evidence underscores the significant influence of paternal preconception health on offspring metabolic outcomes.
