Epidemiología del derrame pleural paraneumónico en la infancia durante la implementación de la vacuna antineumocócica conjugada de 13 serotipos / Epidemiology of pediatric parapneumonic pleural effusion during 13-valent pneumococcal conjugate vaccine implementation

Introducción: La incidencia del derrame pleural paraneumónico, incluyendo el empiema, ha sufrido variaciones en las últimas décadas, que se han relacionado con la implantación de distintos tipos de vacuna antineumocócica conjugada. Métodos: Se han revisado retrospectivamente los datos de los 10 hospitales públicos de la provincia de Alicante (España), que abarcan una población de 279.000 niños menores de 15 años, entre 2010 y 2018. Se desglosaron los derrames menores de 10mm (DP−) y los de 10mm o más (DP+). Resultados: Se han analizado 366 episodios de derrame pleural paraneumónico, 178 DP− (48,6%) y 188 DP+ (51,4%), con una mediana de edad de 4 años (rango intercuartílico: 2-7 años) y una evidente estacionalidad con máximo en invierno y mínimo en verano. Se identificó al agente etiológico por cultivo en 34 pacientes (9,3%), destacando Streptococcus pneumoniae (24 pacientes) seguido por Streptococcus pyogenes (7 pacientes). El serotipo de S. pneumoniae más frecuente fue el 19A (6 pacientes) y se han identificado 3 fallos vacunales. La tasa anual media de incidencia fue de 14,3 casos por 100.000 menores de 15 años (7,0 para DP− y 7,3 para DP+), sin cambios significativos a lo largo del tiempo, aunque sí se apreciaron diferencias marcadas de la incidencia entre los distintos departamentos sanitarios. Conclusiones: No hemos encontrado variaciones temporales en la incidencia del derrame paraneumónico pese a la implementación de la vacuna antineumocócica conjugada de 13 serotipos. Es destacable la variabilidad de la incidencia entre departamentos vecinos sin motivo aparente.(AU)

Introduction: The reported incidence of parapneumonic pleural effusion, including empyema, has shown fluctuations in the last decades. It has been related to the implementation of different types of conjugate pneumococcal vaccines. Methods: We have retrospectively reviewed data from all 10 public hospitals in Alicante Province (Spain) covering a population of 279,000 children under 15 years of age, between 2010 and 2018. Effusions less than 10mm (PE−) and those of 10mm or more (PE+) were separated. Results: A total of 366 episodes of parapneumonic pleural effusion have been analyzed, 178 PE− (48.6%) and 188 PE+ (51.4%), with a median age of 4 years (interquartile range: 2-7 years) and marked seasonality with the maximum in winter and the minimum in summer. A culture proven bacterial agent was identified in 34 patients (9.3%), mainly Streptococcus pneumoniae (24 patients) followed by Streptococcus pyogenes (7 patients). The most frequent S. pneumoniae serotype was 19A (6 patients) and 3 vaccine failures were observed. The mean annual incidence rate was 14.3 cases per 100,000 children under 15 years of age (7.0 for PE− and 7.3 for PE+). No significant changes were observed in incidence over time, but noticeable differences in incidence were observed in different health departments. Conclusions: We have not found temporal variations in incidence of parapneumonic effusion despite the implementation of the 13-valent pneumococcal conjugate vaccine. The unexplained disparity in incidence between close departments is noteworthy.(AU)

Nutrition competencies for undergraduate medical education: Results of an international interdisciplinary consensus.

BACKGROUND: The gap between the nutrition education provided to medical students and the nutrition competencies and attitudes needed for physicians to provide adequate nutrition care is a global concern. There is no universally accepted benchmark on nutrition competencies for doctors. The objective of this study was to establish, by expert consensus, the objectives of undergraduate nutrition medial education, the nutrition core competencies, and strategies for curriculum development in medical nutrition education. METHODS: We administered a Delphi survey to systematically gather the opinion of a panel of Latin American experts in nutrition. The survey questionnaire was constructed considering scientific literature by using a 5-point Likert scale. Consensus was defined as >70% agreement on the importance of an item (Likert scale 4 and 5). RESULTS: A four-round Delphi survey was conducted for this research. In the second, third, and fourth rounds, we validated a total of 130 competencies by consensus, which were distributed into four different thematic areas: (1) basic nutrition concepts, (2) public nutrition and nutrition prevention throughout the life cycle, (3) nutrition status and disease, and (4) nutrition care process. CONCLUSION: The curricula for general physician education in medical school must include health promotion, prevention, and treatment of diseases related to nutrition. This goal can be reached by integrating ≤130 competencies into four different fundamental areas.
