ABSTRACT Objective The objective of our study is to evaluate the clinical outcomes and safety of radiofrequency thermal ablation (RFA) for benign thyroid nodules (BTNs) over a 1-year follow-up. Subjects and methods This is a monocentric retrospective study. Forty-eight patients with solid, non-functioning BTNs were treated by RFA using a 17G internally cooled electrode. We categorized thyroid nodules as small (≤ 12 mL), medium (12 to 30 mL), or large (over 30 mL). BTNs volume reduction, thyroid function, cosmetic and compressive score changes and side effect evaluation at 6 and 12 months were evaluated. Results BTN volume decreased significantly from baseline to 6 (mean percentage decrease of BTN volume was 66.8 ± 13.6%, p < 0.001). At 12 months, the mean percentage reduction of BTN volume compared to six months was 13.7 ± 17.1% (p < 0.001). At 6-month, symptom score had improved significantly (p < 0.001) while it does not change significantly between 6 and 12 months. In particular, symptom score improved significantly in the medium (p < 0.001) and large (p < 0.01) subgroups. Cosmetic score improved significantly between baseline and 6 months (p < 0.001) and between 6 and 12 months (p < 0.01). In all the subgroups, cosmetic score improved significantly between baseline and 6 months, while between 6 and 12 months it improved significantly only in the large group (p < 0.05). RFA was well tolerated. Only one patient experienced permanent right paramedian vocal cord palsy. Conclusions A single RFA treatment was effective in reducing BTNs volume, in particular small and medium nodules. Cosmetic score improved in all treated BTNs while symptom score only got better in the medium and large BTNs.

Aim: This study aims to describe the adherence to the Mediterranean diet (MD), using the KIDMED questionnaire, in a sample of Catalonian adolescents and to assess the association between the MD adherence and socio-economic and lifestyle behaviours. Material and methods: Data are part of a multi-centre longitudinal study designed for the reduction of risk factors of eating and weight-related problems in adolescents. Here, a cross-sectional analysis was performed with the baseline data, academic period 2010-11. The participants were 1,502 adolescents recruited from 11 schools from the province of Barcelona. Results and conclusions: The results showed a higher level of MD adherence when parents had higher educational level, and when adolescents reported a low level of screen-time, and high weekly physical activity.

Objetivo: el objetivo del artículo consiste en describir, mediante el cuestionario KIDMED, la adherencia a la dieta mediterránea (DM) de una muestra de adolescentes catalanes y la asociación entre los niveles de adherencia a la DM y determinadas conductas relacionadas con el estilo de vida y los factores socioeconómicos. Material y métodos: los datos forman parte de un estudio longitudinal multicéntrico diseñado para evaluar los factores de riesgo relacionados con los problemas de la alimentación y el peso. En este trabajo se analizan, en un corte transversal, los datos de la línea base recogidos en el periodo académico 2010-11. Los participantes fueron 1.502 adolescentes reclutados en 11 escuelas de la provincia de Barcelona. Resultados y conclusiones: los resultados indican un elevado nivel de adherencia a la DM cuando los padres tienen un nivel educativo alto y cuando los adolescentes presentan un bajo consumo de tiempo de pantalla y un nivel elevado de actividad física semanal.
