Background/Aims: In adolescents, overweight and obesity are associated with an increased cardiovascular risk. The aim of this study was to determine the impact of a school-based nutritional education program (NEP) on lifestyle changes in Spanish adolescents. Methods: We selected 263 secondary school students (127 males) aged 12–16 years from Granada (Spain), who were followed up throughout 1 school year (2009–2010). At the beginning and end of the school year, data were gathered on the food consumption frequency, and anthropometric and biochemical profile. The NEP comprised a class on nutritional recommendations every 15 days, and administration of a daily breakfast of 275–350 kcal. Results: After the intervention, the prevalence of overweight and obesity decreased among both male and female students (p < 0.001) and there was also a global reduction in the prevalence of the metabolic syndrome (MS) from 32.2 to 19.7% (p < 0.001); in addition, body mass index was significantly decreased in normal weight, overweight and obesity groups (p = 0.001 and p = 0.02, respectively), and high-density-lipoprotein cholesterol and lean body mass was increased in all groups (p = 0.001). Conclusion: The NEP achieved a medium-term reduction in the prevalence of overweight and obesity and had a significant and positive effect on MS components in all groups.

Measurement of the carbon footprint at a regional hospitalBackground: Measuring the carbon footprint (CF) makes it possible to estimate the contribution of clinical activity to global warming. Aim: To measure the emitter components of CO2 equivalents (CO2e) at the Hospital Base, Puerto Montt (HBPM). Material and methods: Descriptive study with data collected retrospectively between January and December 2016 from the HBPM database. The data analyzes direct and indirect emissions as well as other indirect emissions beyond the organizational limits. Results: Of the 9,660.3 tons of CO2e emitted by the HBPM in 2016, 46% were derived from consumption of electricity, 29% derived from the generation of residues, and 10% from clinical gas consumption, of which Sevoflurane was the greatest contributor. Conclusions: Clinical gases are a significant source of CO2e emissions. Sevoflurane alone is in fourth place in CO2e emissions at the HBPM. Estimating the CF produced by HBPM is the first step in the discussion of measures to reduce the environmental impact of our activity. (Rev Med Chile 2018; 146: 1384-1389

Objetivos: evaluar la transferencia de adolescentes desde Cardiología Pediátrica (CP) a Cardiología de Adultos (CA) en el Hospital Dr. Hernán Henríquez de Temuco (HHHT), determinando si recibieron su primera atención en CA en la fecha requerida y si los controles se ajustaron al plazo indicado. Evaluar si la complejidad de la cardiopatía y ruralidad se asocian al cumplimiento en ambos objetivos, en los pacientes sin seguimiento adecuado. Material y Método: revisión de fichas de pacientes atendidos en CP del HHHT que, cumplida la edad requerida, fueron transferidos a CA, entre Octubre 2014-Julio de 2017. Resultados: De 53 pacientes transferidos de CP-CA, 12 (22.6%) tuvo traspaso no efectivo; de ellos, 6 presentaban complejidad moderada-alta (66,6%) y 3 eran rurales (25%). De 28 pacientes ingresados a CA, 14 (50%) tenían seguimiento inefectivo; de ellos 13 (92.6%) tenían cardiopatías de moderada-alta complejidad y 3 (21.5%) provenían de áreas rurales. Conclusiones: la transferencia de CP-CA fue inefectiva en 22.6% de los pacientes; la complejidad de la cardiopatía no se asoció al resultado de la transferencia en este grupo. En CA el seguimiento fue inefectivo en la mitad de los pacientes; de ellos, 92.8% tenían cardiopatías de moderada-alta complejidad, lo que fue estadísticamente significativo respecto de la complejidad en todos los pacientes traspasados. El domicilio no estuvo asociado a la pérdida de pacientes en la transferencia ni en el seguimiento. Estos hallazgos nos permitieron tomar medidas de mejoría en la transferencia y los controles en CA que esperamos mejoren los resultados futuros.
