ABSTRACT
BACKGROUND: The COVID-19 pandemic has posed a huge challenge to healthcare systems and their personnel worldwide. The study of the impact of SARS-CoV-2 infection among healthcare workers (HCW), through prevalence studies, will let us know viral expansion, individuals at most risk and the most exposed areas in healthcare organizations. The aim of this study is to gauge the impact of SARS-CoV-2 pandemic in our hospital workforce and identify groups and areas at increased risk. METHODS AND FINDINGS: This is a cross-sectional and incidence study carried out on healthcare workers based on molecular and serological diagnosis of SARS-CoV-2 infection. Of the 3013 HCW invited to participate, 2439 (80.9%) were recruited, including 674 (22.4%) who had previously consulted at the Occupational Health Service (OHS) for confirmed exposure and/or presenting symptoms suggestive of COVID-19. A total of 411 (16.9%) and 264 (10.8%) healthcare workers were SARS-CoV-2 IgG and rRT-PCR positive, respectively. The cumulative prevalence considering all studies (IgG positive HCW and/or rRT-PCR positive detection) was 485 (19.9%). SARS-CoV-2 IgG-positive patients in whom the virus was not detected were 221 (9.1%); up to 151 of them (68.3%) did not report any compatible symptoms nor consult at the OHS for this reason. Men became more infected than women (25% vs 18.5%, p = 0.0009), including when data were also classified by age. COVID-19 cumulative prevalence among the HCW assigned to medical departments was higher (25.2%) than others, as well as among medical staff (25.4%) compared with other professional categories (p<0.01). CONCLUSIONS: The global impact of the COVID-19 pandemic on HCW of our centre has been 19.9%. Doctors and medical services personnel have had the highest prevalence of SARS-CoV-2 infection, but many of them have not presented compatible symptoms. This emphasizes the performance of continuous surveillance methods of the most exposed health personnel and not only based on the appearance of symptoms.

Objetivos: el parvovirus B19 es uno de los agentes biológicos a tener en cuenta como riesgo a evaluar durante el embarazo de las trabajadoras del área pediátrica del hospital. Su infección durante el embarazo puede tener graves consecuencias para el feto y el riesgo de exposición al mismo es mayor en los puestos de trabajo en contacto con niños. El objetivo principal es conocer el estado inmunitario frente al parvovirus B19 entre los trabajadores del área pediátrica del HUF. El objetivo secundario es mejorar la protección de las trabajadoras embarazadas. Material y Método: se realizó un estudio de seroprevalencia de IgG frente al parvovirus B19 durante el primer trimestre del 2017. Resultados: el 80% de los trabajadores estudiados presentan IgG positiva. Conclusiones: esta prevalencia es mayor que en otras poblaciones de adultos estudiadas. Los estudios de prevalencia existentes son insuficientes, y deben establecerse recomendaciones para la protección de la maternidad en el área de la urgencia pediátrica del hospital
Objectives: parvovirus B19 is one of the biological agents to take into account as risk to assess during the pregnancy of the workers of the pediatric area of the hospital. Its infection during pregnancy can have serious consequences for the fetus and the risk of exposure to it is greater in jobs in contact with children. The main objective is to know the immune status of parvovirus B19 among HUF pediatric health workers. Secondary objective: to improve the protection of pregnant workers. Material and Method: a seroprevalence study of IgG against parvovirus B19 was carried out during the first quarter of 2017. Results: eighty percent of studied workers have positive IgG. Conclusions: this prevalence is higher than in other populations of adults. Existing prevalence studies are insufficient, and should be established

Antecedentes: En anatomía patológica, existen variedad de agentes químicos que deben ser controlados. Por su potencial cancerígeno destacan el Formaldehído (CH2 O), Xileno y los Compuestos Orgánicos Volátiles (COVs). Objetivo: Valorar la eficacia del uso de purificadores mediante la fotocatalización y los sistemas de friocongelación, para el control de los niveles de exposición a CH2 O, Xileno y COVs. Objetivo Secundario: Comparar mediciones de Formaldehído con otros 3 hospitales de la Comunidad de Madrid. Metodología: Se realizaron 26 mediciones ambientales en Anatomía Patológica del Hospital Universitario de Fuenlabrada (HUF), en febrero del año 2017 y en marzo del mismo año, posterior a la instalación de los purificadores y sistemas de friocongelación, en las áreas de laboratorio y sala de tallado. Se valora Xileno y COVs con el método PID (detector de fotoionización, PID por sus siglas en inglés, PhotoIonization Detector) y de CH2 O a través de un Sistema de Detección de Gas. Como criterio para valorar la exposición a COVs se tomó como gas de referencia el isobutileno con un VLA-EC de 100 ppm. Para el Xileno se compararon los resultados con el VLA-EC 100 ppm y para el CH2 O con el VLA-EC de 0,3 ppm, establecidos en la guía de «Límites de Exposición Profesional para Agentes Químicos» del Instituto Nacional de Seguridad e Higiene en el Trabajo. Resultados: Los niveles de exposición previos no superaban los valores límites. Se observó que tras la implantación de las medidas preventivas colectivas estos valores disminuyeron, obteniéndose resultados estadísticamente significativos: COVs (p= 0.0002; IC 95% 2.393- 5.506), Xileno (p= 0.0002; IC 95% 1.021- 2.359) y CH2 O (p= 0.0004; IC 95% 0.210-0.350). Conclusiones: El sistema integral de friocongelación y purificación mediante fotocatalización optimizan el control de la exposición a dichos agentes químicos, anulando las fuentes de emisión
Background: In anatomical pathology, there are a variety of chemical agents that must be controlled due to their carcinogenic potential, such as formaldehyde (CH2 O), Xylene and Volatile Organic Compounds (VOCs). Objective: To evaluate the effectiveness use of purifiers by photocatalysis and freezing systems for the control of exposure levels to CH2 O, Xylene and VOCs. Secondary Objective: To compare the Formaldehyde measurements among other 3 hospitals in the Community of Madrid. Methodology: 26 environmental assessments were performed in the Anatomical Pathology Department at the Hospital Universitario de Fuenlabrada (HUF, Madrid), in February 2017 and in March of the same year, after installing the purifiers and the freezing systems in the laboratory and room carved areas. Xylene and VOCs are evaluated using the PID method (Photo-Ionization Detector) and CH2 O through a Gas Detection System. As a criterion for assessing exposure to VOCs, isobutylene was used as a reference gas with a VLA-EC of 100 ppm. For Xylene the results were compared with the VLA-EC 100 ppm and for the CH2 O with the VLA-EC of 0.3 ppm, established in the guide of "Occupational Exposure Limits for Chemical Agents" from the National Institute of Occupational Safety and Health. Results: Previous exposure levels did not exceed the limit values. It was observed that these values decreased after the implementation of collective preventive measures, obtaining statistically significant results: VOCs (p = 0,0002, 95% CI 2,393-5,506), Xylene (P = 0,0002, 95% CI 1,021-2,359) and CH2 O (p = 0,0004, 95% CI 0,210-0,350). Conclusions: The integrated system of freeze-thawing and photocatalytic purification optimize the exposure control to these chemical agents, canceling emission sources
