RESUMO

Introduction: There is no agreement on the procedures to be used for diagnosis and treatment of gestational thyroid dysfunction. Controversy still exists on the normal range of thyroid-stimulating hormone (TSH) levels and use of gestational hypothyroidism (GH) screening. The aim of this study was to assess diagnosis and treatment of thyroid dysfunction during pregnancy in a group of Spanish hospitals. Study design: This was a retrospective, multicenter study in pregnant females with GH attending Spanish healthcare centers from March 2013 to July 2014. Variables analyzed included diagnosis criteria for GH (availability of universal screening for gestational thyroid disorders and TSH reference values (RVs) by trimester of pregnancy): risk factors for GH, iodine intake from food or supplementation, gestational age (at diagnosis/treatment) and l-thyroxine treatment. Results: Fourteen centers participated in the study. Universal screening was performed in only half of the centers, and only 14% had their own TSH RVs. Overall, 257 pregnant women were enrolled, 53.7% with hypothyroidism (HT) diagnosed before pregnancy (pre-GH) and 46.3% with HT diagnosed during pregnancy (intra-GH). A comparison of intra-GH and pre-GH women showed that intra-GH women made their first visit later (59.7% vs. 75.4% respectively before week 12, p = 0.007) and had more frequently high TSH levels (>2.5 μIU/ml) during the first trimester (94.4% vs. 67.0% respectively, p < 0.001). Conclusions: Our results suggest that GH may be underdiagnosed or inadequately diagnosed in most healthcare centers. These findings suggest the need of improving the current practice in Spain


Introducción: Los procedimientos a seguir para el diagnóstico y tratamiento de la disfunción tiroidea en la gestación no están del todo consensuados. Aún se discute el rango de normalidad de los valores de la hormona estimulante del tiroides (TSH) y el uso de screening para detectar hipotiroidismo gestacional (HG). El objetivo de este estudio es evaluar la forma de diagnóstico y tratamiento de la disfunción tiroidea durante la gestación en un grupo de hospitales de España. Diseño del estudio: Estudio retrospectivo, multicéntrico en mujeres embarazadas con HG atendidas en instituciones sanitarias españolas entre marzo de 2013 y julio de 2014. Las variables analizadas incluyeron criterios diagnósticos de HG (disponibilidad de screening universal para trastornos tiroideos gestacionales y valores de referencia de TSH según el trimestre gestacional); factores de riesgo de HG, ingesta de yodo mediante alimentos o suplementos, edad gestacional (al diagnóstico/tratamiento) y tratamiento con L-tiroxina. Resultados: Participaron un total de 14 centros. Únicamente la mitad de los centros empleaba el screening universal, y solo el 14% tenía valores de referencia de TSH propios. Se incluyeron un total de 257 embarazadas, 53,7% con diagnóstico de hipotiroidismo previo al embarazo (pre-HG) y 46,3% con hipotiroidismo diagnosticado durante el embarazo (intra-HG). Comparando los casos de pre-HG e intra-HG, las mujeres con intra-HG realizaban la primera visita más tarde (antes de la semana 12; 59,7% vs. 75,4% respectivamente, p = 0,007) y tenían más frecuentemente valores elevados de TSH (> 2,5 μUI/ml) durante el primer trimestre (94,4% vs. 67,0% respectivamente, p < 0,001). Conclusiones: Nuestros resultados sugieren que el HG puede estar infradiagnosticado o diagnosticado indebidamente en la mayoría de los centros sanitarios. Estos hallazgos sugieren la necesidad de mejorar la práctica actual en España

RESUMO

Aunque la nutrición de yodo en España ha mejorado en los últimos años, el problema no está resuelto del todo. Es preciso que las Instituciones sanitarias establezcan medidas para garantizar que la nutrición de yodo de toda la población sea la adecuada, especialmente entre los colectivos de mayor riesgo (niños y adolescentes, mujeres en edad fértil, mujeres embarazadas y madres lactantes). Debe aconsejarse un bajo consumo de sal, pero que esta sea yodada. También es imprescindible que las agencias de control alimentario establezcan un control efectivo sobre una adecuada yodación de la sal. En las futuras encuestas de salud debería incluirse indicadores sobre la nutrición de yodo. El estudio EUthyroid y la Declaración de Cracovia sobre la nutrición de yodo brindan una oportunidad para establecer un plan paneuropeo para la prevención de la deficiencia de yodo que debería ser considerada y aprovechada por las autoridades sanitarias


Although iodine nutrition in Spain has improved in recent years, the problem is not completely resolved. It is necessary that health institutions establish measures to ensure an adequate iodine nutrition of the population, especially among the highest risk groups (children and adolescents, women of childbearing age, pregnant women and nursing mothers). A low salt intake should be advised, but it should be iodized. It is also imperative that food control agencies establish effective control over adequate iodization of salt. Indicators on iodine nutrition should be included in future health surveys. The EUthyroid study and the Krakow Declaration on iodine nutrition provide an opportunity to set up a pan-European plan for the prevention of iodine deficiency that should be considered and used by health authorities

RESUMO

PURPOSE: The prevalence of postoperative hypoparathyroidism has been studied in registries and in surgical series with highly variable and imprecise results. However, the frequency of this hormonal deficiency in the clinical practice of endocrinologists is not known with accuracy. We aimed to assess the prevalence and risk factors of hypoparathyroidism in patients undergoing total thyroidectomy in Spain. METHODS: We designed a retrospective, multicentre and nation-wide protocol including all patients with total thyroidectomy who were seen in the endocrinology clinic of the participant centers from January to March 2018. Prevalence of hypoparathyroidism was evaluated at discharge of surgery, 3-6 months after surgery, 12 months after surgery and at last visit. Twenty hospitals participated in the study. RESULTS: Of 1792 patients undergoing total thyroidectomy, 866 (48.3%) developed postoperative hypoparathyroidism at discharge of surgery. Most of them recover parathyroid function over time. Prevalence of hypoparathyroidism at 3-6 months, 12 months and at last visit was 22.9%, 16.7% and 14.5%, respectively. The risk of developing definitive hypoparathyroidism was related to the presence of parathyroid tissue at histology, lymph node dissection, and two-stage thyroidectomy. Patients with thyroid cancer, with higher postoperative calcium levels and treated by expert surgical teams exhibited lower risk of developing permanent hypoparathyroidism. CONCLUSIONS: Although most patients with postsurgical hypoparathyroidism recover parathyroid function, the prevalence of permanent disease in clinical practice is non negligible (14.5%). Postoperative calcium, extent and timing of surgery, the presence of cancer, expert surgical team, and parathyroid tissue at histology are predictors of permanent hypoparathyroidism.

RESUMO

BACKGROUND: Specific data is needed to safely expand bariatric surgery and to preserve good surgical outcomes in response to the non-stop increase in obesity prevalence worldwide. OBJECTIVE: The aims of this study are to provide an overview of the baseline characteristics, type of surgery, and 30-day postoperative morbidity and mortality in patients undergoing bariatric surgery in Spanish public hospitals, and evaluate changes throughout the 2000-2014 period. MATERIAL AND METHODS: This is a descriptive study using data from the RICIBA, a computerized multicenter and multidisciplinary registry created by the Obesity Group of the Endocrinology and Nutrition Spanish Society. Three periods according to the date of surgery were created: January 2000 to December 2004 (G1), January 2005 to December 2009 (G2), and January 2010 to December 2014 (G3). RESULTS: Data from 3843 patients were available (44.8 ± 10.5 years, a 3:1 female-to-male ratio, 46.9 ± 8.2 kg/m(2)). Throughout the 15-year period assessed, candidate patients for bariatric surgery were progressively older and less obese, with an increase in associated comorbidities and in the prevalence of men. The global trend also showed a progressive decrease in Roux-en-Y gastric bypass, the most performed bariatric procedure (75.1 % in G1, 69.3 % in G2, and 42.6 % in G3; p < 0.001), associated with a parallel increase in sleeve gastrectomy (0.8 % in G1, 18.1 % in G2, and 39.6 % in G3; p < 0.001). An overall mortality rate of 0.3 % was reported. CONCLUSIONS: Data from Spain is similar to data observed worldwide. Information recorded in the National Registries like RICIBA is necessary in order to safely expand bariatric surgery in response to increasing demand.
