RESUMO

Introducción: en el hipotiroidismo subclínico pueden aparecer síntomas depresivos y su presencia suele facilitar la instauración de un tratamiento de reemplazo; sin embargo, estudios recientes no han encontrado una asociación entre ambos. Por otra parte, la función tiroidea puede verse afectada por disruptores endocrinos y, algunos de ellos, como los cloratos, pueden encontrarse en el agua que bebemos. Objetivos: conocer si el tipo de consumo de agua puede influir en la aparición de síntomas depresivos en pacientes con hipotiroidismo subclínico. Métodos: participaron 96 mujeres con hipotiroidismo subclínico, sin tratamiento tiroideo, de un área de salud de España. Estudiamos, entre otras variables, la presencia de síntomas depresivos, el tipo de consumo de agua (grifo/embotellada o manantial) y el nivel de cloratos en el agua del grifo. Resultados: el 41,7 % (40) de las mujeres presentaban síntomas depresivos y estos se relacionaban con el consumo de agua del grifo (p = 0,001), resultando este un predictor confiable (OR: 27,79; p = 0,007). El nivel de cloratos en el agua del grifo era de 250 µg/L, valor situado en el límite máximo permitido por la ley. Conclusiones: en mujeres con hipotiroidismo subclínico, la exposición crónica a cloratos en el agua, en niveles autorizados por la ley, podría favorecer la inhibición del transporte de yodo y la aparición de síntomas depresivos. Sería interesante comprobar esta hipótesis, así como su posible efecto sobre otros perfiles poblacionales.(AU)


Introduction: depressive symptoms may develop in subclinical hypothyroidism and their presence usually facilitates recognition and the establishment of replacement treatment; however, recent studies have found no association between the two. Besides, thyroid function can be affected by endocrine disruptors and some of them, such as chlorates, can be found in the water we drink. Objectives: to know if the type of water consumed may influence the development of depressive symptoms in patients with subclinical hypothyroidism. Methods: 96 women with subclinical hypothyroidism, without thyroid treatment, were enrolled. We studied, among other variables, the presence of depressive symptoms, type of water consumption (tap, bottled or spring) and the level of chlorates in the tap water. Results: 41.7 % (40) of women presented depressive symptoms and these were related to the consumption of tap water (p = 0.001), resulting in a reliable predictor (OR, 27.79; p = 0.007). Chlorate level in the tap water was 250 μg/L, a value within the maximum limit allowed by law. Conclusions: chronic exposure to chlorates in water, in women with subclinical hypo-thyroidism, at levels authorized by law, could favor the inhibition of iodine transport and the appearance of depressive symptoms. It would be interesting to test this hypothesis as well as its possible effect on other population profiles.(AU)

RESUMO

The food industry is constantly attempting to develop better products that will have a positive effect on health. Feiraco® and Clesa®, expressed their intention to create novel products using UNICLA® milk as a matrix to develop functional foods. In this respect, ß-cyclodextrin (ß-CD) at 1% was able to reduce the cholesterol concentration in Feiraco-UNICLA® milk products by around 87-85%. Products were fortified with omega-3 from fish oil with α- and ß-CD acting as carriers. It was possible to add around 50% of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) Recommended Dietary Allowances (RDA), with a high diet proportion of fibre and similar organoleptic properties to commercial omega-3 products. 80% of a sensory panel found our formulations satisfactory. The final product was stable, and the bioaccessibilty of the fatty acids added to the milk was around 74%. These results as a whole satisfy the aid of Feiraco® and Clesa® to develop improved products.

RESUMO

Introducción: el síndrome metabólico de las mujeres posmenopáusicas puede mejorar con una alimentación saludable. Objetivos: evaluar si una intervención alimentaria con productos lácteos enriquecidos en selenio y ácidos grasos poliinsaturados omega-3 aumenta los niveles de selenio y mejora los factores de riesgo cardiovascular en las mujeres posmenopáusicas con síndrome metabólico. Material y métodos: ensayo clínico aleatorizado, triple ciego y controlado, realizado en atención primaria. Captación: abril 2018, 46 mujeres posmenopáusicas con síndrome metabólico consumidoras habituales de lácteos. Aleatorización: 23 en el grupo de control y 23 en el grupo experimental. Intervención: consumo durante 3 meses de lácteos enriquecidos naturalmente con selenio y ácidos grasos poliinsaturados omega-3 (leche, yogur y queso fresco). Controles: consumo de lácteos convencionales. Variable principal: selenio en plasma; secundarias: criterios del síndrome metabólico. Número de registro 2018/256, Comité de Ética Galicia. Resultados: finalizaron 23 mujeres en el grupo de control y 21 en el grupo de intervención. Aumentó el selenio en el grupo de intervención (7,2 µg/L, IC del 95 %: 3,7/10,8) frente al grupo de control (-4,5 µg/L, IC del 95 %: -8/-1) (p < 0,001) y disminuyó el colesterol unido a lipoproteínas de muy baja densidad (-2,3 mg/dl, IC del 95 %: -5,6/1) respecto al grupo de control (1,9 mg/dl, IC del 95 %: -0,7/4,5) (p = 0,043). Las mujeres del grupo experimental mejoraron respecto a su medición basal en perímetro de cintura (p = 0,010), índice de masa corporal (p = 0,047) y colesterol unido a lipoproteínas de alta densidad (p < 0,001). Conclusiones: una intervención con lácteos enriquecidos naturalmente con selenio y omega-3 en mujeres posmenopáusicas con síndrome metabólico puede mejorar los niveles de selenio en plasma y de colesterol unido a lipoproteínas de muy baja densidad.

Introduction: metabolic syndrome in postmenopausal women can improve with a healthy diet. Objectives: to evaluate whether a dietary intervention with dairy products naturally enriched with selenium and omega-3 polyunsaturated fatty acids increases selenium plasma levels and improves cardiovascular risk factors in postmenopausal women with metabolic syndrome. Material and methods: a randomized, triple-blind, controlled clinical trial carried out in GP surgeries. Recruitment: April 2018, 46 postmenopausal women with metabolic syndrome who were frequent dairy consumers. Randomization: 23 in control group and 23 in experimental group. Intervention: consumption of dairy products naturally enriched with selenium and omega-3 polyunsaturated fatty acids (milk, yogurt, fresh cheese) for three months. Controls took conventional dairy. Primary endpoint: plasma selenium levels; secondary endpoints: metabolic syndrome criteria. Registration number 2018/256, Galicia Ethics Committee. Results: in all, 23 women in the control group and 21 in the intervention group completed the trial. Selenium increased in the intervention group (7.2 µg/L, 95 % CI, 3.7/10.8) compared to the control group (-4.5 µg/L, 95 % CI, -8/-1) (p < 0.001) and very low-density lipoprotein cholesterol decreased (-2.3 mg/dL, 95 % CI, -5.6/1) compared to the control group (1.9 mg/dL, 95 % CI, -0.7/4.5) (p = 0.043). Waist circumference (p = 0.010), body mass index (p = 0.047) and high-density lipoprotein cholesterol (p < 0.001) in the experimental group improved in comparison to baseline measurements. Conclusions: an intervention with dairy products naturally enriched with selenium and omega-3 in a sample of postmenopausal women with metabolic syndrome can improve plasma selenium levels and very low-density lipoprotein cholesterol.

RESUMO

The effect of two sources of Se, selenized yeast (Se-Y) and sodium selenite, added to total mixed rations (TMR) fed to cows on Se milk content and distribution in milk components was studied on three farms for 6 weeks. The maximal increase in milk Se was attained with Se-Y supplemented at 0.3 microg g(-1). The effect was immediate, with an increase of 9 microg L(-1) being observed after only 5 days, and remained steady until the last sample at day 40 of Se supplementation. Se distribution in milk components was constant, 53.6, 42.6, and 9.3% in whey, casein, and fat, respectively, and was unaffected by the form of supplementation. The effect of the level of Se-Y supplementation on milk Se was studied on two farms. Increasing dietary Se-Y from 0 to 0.5 microg g(-1) elevated milk Se content from 20 to 39 microg L(-1). Se-enriched cow's milk at different levels can be produced by varying dietary Se supplementation in the form of selenized yeast.
