Background: Malnutrition in critically ill adults in the intensive care unit (ICU) is associated with a significantly elevated risk of mortality. Adequate nutrition therapy is crucial to optimise outcomes. Currently, there is a paucity of such data in Latin America. Our aims were to characterise current clinical nutrition practices in the ICU setting in Latin America and evaluate whether current practices meet caloric and protein requirements in critically ill patients receiving nutrition therapy. Methods: We conducted a cross-sectional, retrospective, observational study in eight Latin American countries (Argentina, Brazil, Chile, Colombia, Ecuador, Mexico, Panama, and Peru). Eligible patients were critically ill adults hospitalised in the ICU and receiving enteral nutrition (EN) and/or parenteral nutrition (PN) on the Screening Day and the previous day (day −1). Caloric and protein balance on day -1, nutritional status, and prescribed nutrition therapy were recorded. Multivariable logistic regression analysis was performed to identify independent predictors of reaching daily caloric and protein targets. Results: The analysis included 1053 patients from 116 hospitals. Evaluation of nutritional status showed that 74.1% of patients had suspected/moderate or severe malnutrition according to the Subjective Global Assessment. Prescribed nutrition therapy included EN alone (79.9%), PN alone (9.4%), and EN + PN (10.7%). Caloric intake met >90% of the daily target in 59.7% of patients on day -1; a caloric deficit was present in 40.3%, with a mean (±SD) daily caloric deficit of -688.8 ± 455.2 kcal. Multivariable logistic regression analysis showed that combined administration of EN + PN was associated with a statistically significant increase in the probability of meeting >90% of daily caloric and protein targets compared with EN alone (odds ratio, 1.56; 95% confidence interval, 1.02-2.39; p = 0.038). Conclusions: In the ICU setting in Latin America, malnutrition was highly prevalent and caloric intake failed to meet targeted energy delivery in 40% of critically ill adults receiving nutrition therapy. Supplemental administration of PN was associated with improved energy and protein delivery; however, PN use was low. Collectively, these findings suggest an opportunity for more effective utilisation of supplemental PN in critically ill adults who fail to receive adequate nutrition from EN alone.

Objetivo El objetivo de este estudio fue evaluar el patrón de consumo de bebidas energizantes en una muestra de estudiantes de dos colegios públicos y dos privados de Bogotá.Método Se realizó un estudio transversal. Se incluyeron 671 escolares de 10 a 20 años. Se analizaron las medidas antropométricas y la encuesta de frecuencia de consumo de alimentos a través de un cuestionario autoaplicado.Resultados El 80% tenía IMC normal, 12,4% de sobrepeso, 3,6% de obesidad. No hay asociación entre el IMC y el consumo de bebidas energéticas (p=0,514). El consumo de bebidas energéticas por parte de los estudiantes se asocia con el ejercicio físico (p=0,01) y el consumo de bebidas alcohólicas (p=0,000).Conclusiones El consumo de bebidas energizantes está asociado con el ejercicio físico y el consumo de alcohol. Los hallazgos demuestran la importancia de establecer campañas educativas destinadas a informar sobre los peligros de ingerir estas bebidas e incluso el mezclarlas con alcohol etílico.
