Relación entre el volumen espiratorio máximo en un segundo, el índice BODE y la calidad de vida percibida por el paciente de enfermedad pulmonar obstructiva crónica / Relation between maximum expiratory volume in one section, BODE index and quality of life perceived by the chronic obstructive pulmonary disease patient

Objetivo: Evaluar la correlación existente entre la calidad de vida percibida por los pacientes y dos parámetros objetivos de gravedad: a) la gravedad de la obstrucción por el volumen espiratorio máximo en el primer segundo (FEV1), y b) el índice BODE (Body Mass Index, Airflow Obstruction, Dyspnea and Exercice Capacity). Material y métodos: Estudio observacional descriptivo de corte transversal, realizado en 40 pacientes diagnosticados de la enfermedad pulmonar obstructiva crónica (EPOC) y clasificados según la escala GOLD (Global initiative for chronic obstructive lung disease) en moderados o graves, a los que se entrevistó mediante el cuestionario respiratorio de St. George (SGRQ). Se calculó el índice BODE, previa medición de los parámetros que lo componen. También se recogieron datos antropométricos y demográficos de los pacientes. Resultados: De los 40 pacientes del estudio, 38 eran varones (95%), con una edad media ± desviación estándar (DE) de 76,15 ± 5,82 años. Las medias ± DE obtenidas en referencia a la variable subjetiva del cuestionario SGRQ fueron de 33,58 ± 18,14. En referencia a los datos conseguidos de las variables objetivas, obtuvimos del FEV1 una media ± DE de 49,05 ± 15,731, y del índice BODE de 2,33 ± 1,8 y de sus parámetros integrantes: test de los 6 minutos, 440 ± 87,9; escala Medical Research Council, 1,4 ± 0,6; índice de masa corporal, 28,16 ± 4,4. Según los valores obtenidos observamos la existencia de correlación entre SGRQ y el índice BODE, al igual que entre la actividad, como subescala de la SGRQ y el índice BODE. Conclusiones: El resultado del índice BODE se correlaciona débilmente con los resultados de la SGRQ de forma conjunta, por lo que un elevado índice BODE afecta negativamente a la calidad de vida de los pacientes con EPOC moderados o graves (AU)

Objective: To measure the correlation between perceived quality of life and two objective severity parameters: forced expiratory volume in one second (FEV1) and body mass, airflow obstruction, dyspnea and exercise capacity (BODE) index. Material and methods: Observational descriptive cross-sectional study involving 40 Chronic Obstruction Pulmonary Disease (COPD) patients. They were classified using the Global Initiative for Chronic Obstructive Lung Disease (GOLD) classification system into moderate or severe. The Saint George Respiratory Questionnaire (SGRQ) was carried out by interview and the BODE value was analyzed after measurement of the parameters included in it. Anthropometry and demography data were also collected. Results: A study including 40 patients, 38 of them men 38 (95%), with mean age 76.15 ± 5.82 was performed. The means obtained for the subjective variable of the SGRQ was 33.58 ± 18.14. Regarding the data obtained for the objective variables, the FEV1 had a mean of 49.05 ± 15.731, and the BODE index showed 2.33 ± 1.8. The parameters making it up were: 6-minute exercise test 440 ± 87.9, mean MRC score: 1.4 ± 0.6, and body mass index (BMI) 28.16 ± 4.4. According to the values obtained, we observed the existence of a correlation between SGRO and the BODE index and between the activity, and subscale of the SGRO and BODE index. Conclusions: The BODE index are weakly correlative with the results of the SGRO combined. High index BODE negatively affects the perceived quality of life of moderate/severe COPD patients (AU)

Estudio de prevalencia de la deficiencia de yodo en una población escolarizada de 6 años / Prevalence study of iodine deficiency in a 6-year-old school population

Introducción: El yodo es un oligoelemento cuyo déficit provoca diferentes complicaciones agrupadas bajo el nombre de trastornos por déficit de yodo. La ingesta de alimentos ricos en yodo es la única vía de administración del mismo. Se considera déficit leve de yodo una yoduria inferior a 100μg/l; aumentando la posibilidad de trastornos por déficit de yodo. Objetivo: Determinar la prevalencia de déficit de yodo en los niños de 6 años de la provincia de Lleida. Métodos: Estudio trasversal de selección aleatoria, en niños escolarizados en la provincia de Lleida. Tras la aceptación, se cumplimentó un cuestionario y se realizó un análisis de orina para determinar el nivel de yodo. Resultados: Inclusión de 328 niños (5 sin muestra de orina), 46,8% varones, 54,27% en escuelas públicas, 17,2% inmigrantes y 40,95% utilizaba el comedor escolar. El 62,42% comía pescado 2 o más veces a la semana, sal yodada el 60,98% y el 90,65% leche diariamente. La yoduria media se situó en 234,4μg/l (DT=133,7). El déficit de yodo fue establecido al 9,29% (6,12–12,45%) de la muestra, relacionándose significativamente con el tipo de centro (concertado o público), origen del niño, sal yodada, consumo de pescado y leche. Conclusiones: La prevalencia de déficit leve de yodo en Lleida es inferior a la de estudios parecidos anteriores, mostrando unos buenos parámetros nutricionales. El déficit de yodo es superior en niños inmigrantes, aunque se presentan modificaciones nutricionales que pueden establecer mejoras superiores a la de la población autóctona (AU)

Introduction: Iodine is a dietary element, a deficiency of which leads to complications grouped with the name Iodine Deficiency Disorders (IDD). The intake of foods rich in iodine is the only route of iodine administration. Iodine is considered to deficient when its concentration is less than 100μg/L in urine, thus increasing the possibility of IDD. Aim: To determine the prevalence of iodine deficiency in 6-year-old school children in the region of Lleida. Methods: A randomised cross-sectional study of 6-year-old school children in the area of Lleida was selected. After the acceptance, a questionnaire had to be filled in and a urine sample was collected to determine the urinary iodine. Results: A total of 328 subjects were included (5 without urine sample), 46.8% boys, 54.27% in public schools, 17.2% immigrants and 40.95% had lunch at school. The majority (62.42%) ate fish twice or more a week, 60.98% used iodised salt and 90.65% drank milk daily. The iodine mean was 234.4μg/l (SD=133.7). Only 9.29% (6.12–12.45%) had iodine deficiency which was associated to the type of school the children attended (private or public), immigrant origin, iodised salt, fish and milk nutrition. Conclusions: The prevalence of iodine deficiency in Lleida is lower than in previous publications, shown by the good nutrition parameters. The shortage of iodine is higher in immigrant boys, although better nutrition measures could be taken to improve their situation (AU)
