ABSTRACT
El objetivo de este trabajo fue investigar qué medidas se podrían tomar para aumentar los niveles generales de actividad física del alumnado de sexto de Educación Primaria durante los periodos de recreo escolar. Se implementó un programa específico desde el currículum de la asignatura de Educación Física y, después de haber finalizado la aplicación del citado programa, se comprobó los niveles de actividad física. También se realizó una observación pasados treinta días de su finalización, con el fin de comprobar en qué medida se modifican los hábitos de actividad física. El instrumento de recogida de datos fue el podómetro, que los participantes utilizaron durante los periodos de recreo escolar. El análisis de los resultados permite afirmar que la aplicación del programa específico objeto de estudio incide positivamente sobre el incremento del volumen de actividad física que realiza el alumnado en su tiempo libre y que, pasados treinta días desde su aplicación, el alumnado mantiene parte de incremento adquirido, modificando su hábito de actividad durante el recreo escolar
The objective of this work was to investigate what measures could be taken to increase the general levels of physical activity of students in sixth grade of Primary Education during the school breaks. A specific program was implemented from the curriculum of the subject of Physical Education and, after completing its application, physical activity levels were analyzed. In addition, an observation was conducted thirty days after its completion, in order to verify to what extent the habits of physical activity are modified. The instrument of data collection was the pedometer, which the participants used during the periods of school break. The analysis of the results allows affirming that the application of the specific program object of study affects positively on the increase of the volume of physical activity that the students do in their free time and that, after thirty days from its application, the students keep part of this increase acquired, which means a change in their activity habit during school breaks

It is important to know the spectrum of the microbial aetiology of prosthetic joint infections (PJIs) to guide empiric treatment and establish antimicrobial prophylaxis in joint replacements. There are no available data based on large contemporary patient cohorts. We sought to characterize the causative pathogens of PJIs and to evaluate trends in the microbial aetiology. We hypothesized that the frequency of antimicrobial-resistant organisms in PJIs has increased in the recent years. We performed a cohort study in 19 hospitals in Spain, from 2003 to 2012. For each 2-year period (2003-2004 to 2011-2012), the incidence of microorganisms causing PJIs and multidrug-resistant bacteria was assessed. Temporal trends over the study period were evaluated. We included 2524 consecutive adult patients with a diagnosis of PJI. A microbiological diagnosis was obtained for 2288 cases (90.6%). Staphylococci were the most common cause of infection (1492, 65.2%). However, a statistically significant rising linear trend was observed for the proportion of infections caused by Gram-negative bacilli, mainly due to the increase in the last 2-year period (25% in 2003-2004, 33.3% in 2011-2012; p 0.024 for trend). No particular species contributed disproportionally to this overall increase. The percentage of multidrug-resistant bacteria PJIs increased from 9.3% in 2003-2004 to 15.8% in 2011-2012 (p 0.008), mainly because of the significant rise in multidrug-resistant Gram-negative bacilli (from 5.3% in 2003-2004 to 8.2% in 2011-2012; p 0.032). The observed trends have important implications for the management of PJIs and prophylaxis in joint replacements.
