Early childhood is a critical period for obesity prevention. This randomized controlled study evaluated the effectiveness of an educational intervention preventing obesity in preschool-age children. A nutritional education intervention, with a follow-up session one year later, was conducted with parents of children aged 3 to 4 years of public schools in the province of Málaga. The main outcome variable was the body mass index z-score (zBMI). The prevalence of overweight or obesity was the secondary outcome variable. The sample comprised 261 students (control group = 139). Initial BMI, weight, height-for-age and prevalence of overweight and obesity were similar for both groups. After the first year of the intervention, the zBMI of the intervention group decreased significantly from 0.23 to 0.10 (p = 0.002), and the subgroup of patients with baseline zBMI above the median decreased from 1 to 0.72 (p = 0.001), and in the second year from 1.01 to 0.73 (p = 0.002). The joint prevalence of overweight and obesity increased in the control group (12.2% to 20.1%; p = 0.027), while in the intervention group, there were no significant changes. This preschool educational intervention with parents improved their children’s BMI, especially those with a higher BMI for their age, and favored the prevention of overweight or obesity.
Aims: To evaluate the relationship between daily sensor scan rates and changes in HbA1c and hypoglycemia in children. Methods: We enrolled 145 paediatric T1D patients into a prospective, interventional study of the impact of the FreeStyle Libre 1 system on measures of glycemic control. Results: HbA1c was higher at lower scan rates, and decreased as the scan rate increased to 15–20 scans, after which it rose at higher scan rates. An analysis of the change in hypoglycemia, based on the number of daily sensor scans, showed there was a significant correlation between daily scan rates and hypoglycemia. Subjects with higher daily scan rates reduced all levels of hypoglycaemia. Conclusions: HbA1c is higher at lower scan rates, and decreases as scan rate increases. Reductions in hypoglycemia were evident in subjects with higher daily scan rates.
Introducción. La miotonía congénita es la forma más común de miotonía de causa genética y se produce por mutaciones en el gen CLCN1 . Puede heredarse de manera autosómica dominante o recesiva. Presentamos una serie de casos para actualizar su incidencia en nuestro medio, para describir su fenotipo en relación con el genotipo encontrado y, además, revisamos las mutaciones encontradas, entre las que aportamos una nueva alteración no descrita. Casos clínicos. Se revisaron las historias clínicas de pacientes con diagnóstico de miotonía congénita estudiados y seguidos en la consulta de neurología pediátrica en un hospital de tercer nivel entre los años 2015 y 2020. Se recogieron variables demográficas (edad y sexo), curso de la enfermedad (edad de inicio, síntomas y signos, tiempo transcurrido hasta el diagnóstico y evolución clínica), antecedentes familiares y evaluación de la respuesta al tratamiento. Se identificaron cinco casos con diagnóstico clínico de miotonía congénita (tres con enfermedad de Becker y dos con enfermedad de Thomsen). La incidencia en relación con el número de nacimientos la estimamos en 1:15.000 recién nacidos para los casos con fenotipo Becker y en 1:21.000 recién nacidos para los fenotipos Thomsen. Hallamos una mutación probablemente patogénica no descrita previamente ( CLCN1: c.824T>C). Conclusiones. La incidencia aproximada en nuestro medio fue superior a la previamente conocida y describimos una nueva mutación no descrita: c.824T>C, con predictores de patogenicidad, que se comportó como un fenotipo recesivo Becker, pero con inicio más temprano.
