Artificial Neural Network for Predicting Iodine Deficiency in the First Trimester of Pregnancy in Healthy Women
2020
Iodine deficiency in Spain is a persisting public health problem and the prescription of potassium iodide is recommended during pregnancy. The purpose of this study was to develop an Artificial Neural Network (ANN) to predict the risk factors of iodine deficiency during pregnancy, and compare the results obtained with a logistic regression model. Two hundred forty-four healthy pregnant women were included in a descriptive and prospective study in their first trimester of pregnancy. The women enrolled were asked specifically about their use of supplements containing potassium iodide, iron, folic acid and/or multivitamins during pregnancy. The consumption of iodine-rich foods was assessed thr…
Relationship between Thyroid Status during the First Trimester of Pregnancy and Neonatal Well-Being
2021
Iodine is an essential micronutrient for the synthesis of thyroid hormones. The proper functioning of the thyroid axis is essential for the normal development of the nervous system, especially in the first trimester of gestation. The aim of the present study was to analyze the perinatal outcomes, anthropometry, and APGAR test scores of newborns and to relate them to maternal thyroid status. A total of 190 newborns participated in the study. No correlation was found between thyroid stimulating hormone (TSH) and maternal ioduria values in the first trimester of gestation with the weight or length of the newborn, or the APGAR score at one minute after birth. However, we found significant diffe…
Joda deficīts grūtniecēm teritoriālā griezumā un tā ietekme uz intelektuālo attīstību bērniem Latvijā
2015
Latvijā ilgstoši pastāv joda deficīts, kas ir bīstams sabiedrības veselībai un intelektuālajai attīstībai. Pat neliels joda deficīts grūtniecības periodā izraisa bērna IQ pazemināšanos, līdz ar to vēlāk arī iespējamu valsts IKP per capita samazināšanos. Uzdevumi: izvērtēt joda pietiekamību Latvijas grūtniecēm reģionālā griezumā, sakarības ar saistītiem faktoriem, kā arī censties identificēt sakarību starp joda koncentrāciju urīnā (JU) skolēniem un atzīmēm valsts eksāmenos. Visos Latvijas reģionos grūtniecēm konstatēts joda deficīts (mediānā JU 64.5-89.9 µg/g Cr). Starp grūtnieču JU un jodu saturošu vitamīnu lietošanu statistiski ticama sakarība atrasta tikai Zemgalē, bet ar jodsāls lietošan…
2021 European Thyroid Association Guidelines for the Management of Iodine-Based Contrast Media-Induced Thyroid Dysfunction
2021
Given the fact that a large number of radiological examinations using iodine-based contrast media (ICM) are performed in everyday practice, clinicians should be aware of potential ICM-induced thyroid dysfunction (TD). ICM can induce hyperthyroidism (Hyper) or hypothyroidism (Hypo) due to supraphysiological concentrations of iodine in the contrast solution. The prevalence of ICM-induced TD varies from 1 to 15%. ICM-induced Hyper is predominantly found in regions with iodine deficiency and in patients with underlying nodular goiter or latent Graves’ disease. Patients at risk for ICM-induced Hypo include those with autoimmune thyroiditis, living in areas with sufficient iodine supply. Most cas…
Iodine Deficiency in Latvia: Current Status and Need for National Recommendations
2017
Abstract In the absence of a mandatory salt iodisation programme, two nationwide cross-sectional cluster surveys revealed persisting iodine deficiency among Latvian schoolchildren during the spring season and a noteworthy iodine deficiency in pregnant women in Latvia; these deficiencies warrant intervention. The consequences of mild-to-moderate iodine deficiency during pregnancy and lactation can adversely affect foetal brain development. Data from a Latvian population survey revealed the consumption of approximately 100 μg of iodine per day through foods and iodised salt. Therefore, strategies to increase the consumption of iodine-containing products should be implemented, particularly for…
Milk as an Essential Source of Iodine in Latvian Population
2017
Abstract Milk and dairy products are studied as alternative iodine sources, because salt iodisation is controversial due to high salt consumption leading to cardiovascular diseases. However, the iodine concentration in milk markedly varies. This study evaluated the iodine concentration in cow’s milk available in the Latvian market. Iodine and fat concentration was analysed with a spectrophotometer “Varian Cary 50” based ISO 2446:2008 in 20 milk samples. Data from the Central Statistical Bureau and survey among pregnant women were used to analyse milk product consumption and its impact on iodine status. Average iodine concentration in milk samples was 457.6 (179.6) μg/L, winter samples had a…
Neonatal screening for congenital hypothyroidism in an Italian Centre: a 5-years real-life retrospective study
2021
Abstract Introduction Congenital hypothyroidism is an endocrine disease with a significant incidence in the general population (1:2000–1:3000 newborns in Italy) and a different geographical distribution, partially explained by endemic iodine deficiency, genetic traits and autoimmune thyroid diseases. Objectives Aims of this study are: to evaluate the incidence of positive neonatal blood spot screening for CH in western Sicily, identified by the screening centre of the Children Hospital “G. Di Cristina”, ARNAS, Palermo; to evaluate the impact of a lower TSH cutoff in the neonatal blood spot screening for CH. Materials and methods The TSH threshold of the neonatal screening was established as…
Ensuring Effective Prevention of Iodine Deficiency Disorders
2016
To access publisher's full text version of this article click on the hyperlink at the bottom of the page Programs initiated to prevent iodine deficiency disorders (IDD) may not remain effective due to changes in government policies, commercial factors, and human behavior that may affect the efficacy of IDD prevention programs in unpredictable directions. Monitoring and outcome studies are needed to optimize the effectiveness of IDD prevention. Although the need for monitoring is compelling, the current reality in Europe is less than optimal. Regular and systematic monitoring surveys have only been established in a few countries, and comparability across the studies is hampered by the lack o…
Standardized Map of Iodine Status in Europe
2020
Background: Knowledge about the population's iodine status is important, because it allows adjustment of iodine supply and prevention of iodine deficiency. The validity and comparability of iodine-related population studies can be improved by standardization, which was one of the goals of the EUthyroid project. The aim of this study was to establish the first standardized map of iodine status in Europe by using standardized urinary iodine concentration (UIC) data. Materials and Methods: We established a gold-standard laboratory in Helsinki measuring UIC by inductively coupled plasma mass spectrometry. A total of 40 studies from 23 European countries provided 75 urine samples covering the wh…
Iodine deficiency during pregnancy: a national cross-sectional survey in Latvia
2015
AbstractObjectiveLow iodine intake during pregnancy may cause thyroid dysfunction, which results in inadequate fetal brain development. In the absence of a universal salt iodization programme, we conducted a nationwide survey of iodine deficiency in pregnant women in Latvia.DesignA countrywide twenty-cluster survey, with at least twenty women per cluster. Participants completed a questionnaire on dietary habits concerning iodine intake (n 739). Thyroid function (thyroid-stimulating hormone, free thyroxine and thyroperoxidase antibodies) was measured (n 550). Urinary iodine was measured using the ammonium persulfate method (n 696).SettingThe survey was performed in all regions of Latvia duri…
