Developing a faster way to identify biocontamination in the air of controlled environment rooms with HEPA filters: airborne particle counting.

Our aim was to assess whether airborne particle counting is an immediate indicator of biocontamination in controlled environment rooms with HEPA filters in a hospital. A prospective study was carried out in a tertiary care hospital between 2016 and 2018. The study was divided in two periods and the measurements were performed in different controlled environment rooms with HEPA filters. The Environmental Biosafety Criterion (EBC) was defined as the absence of fungal and bacterial contamination. In the training period, the area under the ROC curve (aROC) of airborne particle counting and EBC was calculated for each particle size as well as the cut-off points that optimize the combination of sensitivity and specificity in the association between them. aROC is created by plotting sensitivity against 1-specificity. In the testing period, the cut-off points previously selected were validated. 328 measurements were carried out in the training period and 301 in the testing period. In the training period, an association was found between airborne particle counting and EBC. An aROC = 0.760, 95% Confidence Interval (95% CI) 0.695-0.825 was observed for 0.3 µm particles; an aROC = 0.797 (95% CI 0.734-0.860) for 0.5 µm particles; and an aROC = 0.751 (95% CI 0.673-0.829) for 5 µm particles. The cut-off points that optimized the combination of sensitivity and specificity were 9.0 × 103 for 0.3 µm particles, 3.6 × 103 particles for 0.5 µm, and 3.2 × 102 particles for 5 µm. In the testing period, the previous cut-off points were validated. We conclude that airborne particle counting is a useful, immediate, and preliminary measure to identify the presence of biocontamination in controlled environment rooms with HEPA filters.

Descenso de la incidencia de la varicela en la Comunidad de Madrid tras la vacunación infantil universal. Años 2001-2015 / Decrease in the incidence of chickenpox in the Community of Madrid after universal childhood immunization. Years 2001-2015

Objetivo: La vacuna frente a la varicela se recomendó en la Comunidad de Madrid (CM) a los 15 meses de edad entre noviembre de 2006 y diciembre de 2013. El objetivo fue describir el impacto de la vacunación sobre la incidencia de la varicela en la CM durante el período 2001-2015. Diseño: Estudio descriptivo de los casos de varicela notificados a la Red de Médicos Centinela de la CM y de los casos registrados en el Conjunto Mínimo Básico de Datos al alta hospitalaria. Se calculó la incidencia de casos y de ingresos de varicela, total y específica por edad y sexo. Resultados: La incidencia fue un 94,0% menor en el período 2012-2013 que en el período 2001-2003. En el período 2014-2015 la incidencia fue un 61,8% superior que en el período 2012-2013. La incidencia más alta se apreció en los niños de 0-4 años excepto en el período 2010-2014, en el que fue superada por la del grupo de 5-9 años. La tendencia de los ingresos hospitalarios también fue decreciente, siendo el grupo de menores de un año el de mayor incidencia. Conclusiones: La recomendación de vacunar a los 15 meses de edad ha producido un importante descenso de la incidencia de casos y de ingresos por varicela en todos los grupos de edad, lo que es compatible con la efectividad de una dosis y su capacidad para producir inmunidad de grupo. La retirada de esta recomendación en 2014 y 2015 ha conllevado un incremento de la incidencia (AU)

Objective: Varicella vaccine was recommended in the Community of Madrid (CM) at 15 months of age between November 2006 and December 2013. The objective was to describe the impact of vaccination on the incidence of varicella in the CM during the period 2001-2015. Design: A descriptive study of cases of varicella reported to the Sentinel Physician Network of the CM and the cases recorded in the Minimum Basic Data Set at hospital discharge was carried out. Total incidence of cases and of hospital admissions were calculated, as well as specific incidence by age and sex. Results: The incidence was 94.0% lower between 2012 and 2013 than between 2001 and 2003. Between 2014 and 2015 the incidence was 61.8% higher than between 2012 and 2013. The highest incidence was observed in children aged 0 to 4 years except for 2010-2014, which was exceeded by the incidence in children aged 5 to 9. The trend in hospital admissions was also decreasing, with the highest incidence in children aged 0 to 1 year, followed by 1-4 years. Conclusions: There has been a significant decrease in the incidence of cases and of hospital admissions by varicella in all age groups after the recommendation to vaccinate at 15 months of age, which is compatible with the effectiveness of a dose and its ability to produce immunity group. The withdrawal of this recommendation between 2014 and 2015 has led to an increase in the incidence (AU)
