Introduction: Urban air pollution (UAP) is a major threat to child and adolescent health. Children are more vulnerable to its effects, being associated with higher morbidity and mortality due to acute and chronic diseases, especially respiratory ones. A study is performed on the relationship between UAP and the rate of hospital admissions due to acute respiratory diseases. Patients and methods: An ecological study was conducted on young people under 19 years-old in the city of Murcia, who had visited hospital emergency departments due to respiratory diseases (ICD-9) during 2015. A logistic regression was performed on the risk of hospital admission that included consultations in relation to the average daily levels of environmental pollutants (NO2, O3, PM10, SO2) obtained from the Air Quality Surveillance and Control network of the Region of Murcia. Other control variables, such as gender, age, average daily ambient temperature, and season of the year. Results: A total of 12,354 (56% boys and 44% girls) children consulted in the emergency department for respiratory disease. Of those, 3.5% were admitted, with a mean age of 2.54 (95% CI; 2.16−2.91) years. The Odds Ratio (OR) of hospital admission for respiratory diseases: NO2 1.02 (95% CI; 1.01–1.04; P

Resumen: Introducción: La contaminación atmosférica urbana es una amenaza principal para la salud infantojuvenil. Los niños son más vulnerables a sus efectos asociando mayor morbimortalidad de enfermedades agudas y crónicas, especialmente respiratorias. Pretendemos estudiar los efectos de la contaminación atmosférica urbana en la tasa de ingresos hospitalarios por causa aguda respiratoria. Pacientes y métodos: Estudio ecológico durante 2015 de las visitas con patología respiratoria (CIE-9) de urgencias hospitalarias en menores de 17 años en el municipio de la ciudad de Murcia. Regresión logística para el riesgo de ingreso hospitalario entre las consultas en relación con los niveles promedios diarios de contaminantes ambientales (NO2, O3, PM10, SO2) obtenidas de la Red de Vigilancia y Control de la Calidad del Aire de la Región de Murcia. Otras variables de control: sexo, edad, temperatura ambiental media diaria, y estación del año. Resultados: Un total de 12354 niños consultaron en urgencias por patología respiratoria, 56% niños y 44% niñas. Ingresaron el 3,5%, con edad media de 2,54 (IC95% 2,16-2,91) años. Para el riesgo de ingreso hospitalario por enfermedades respiratorias: NO2 1,02 (IC95% 1,01-1,04; p

CF-COVID19-Spain Registry Group., [Background] Given the high incidence of confirmed infection by SARS-CoV-2 and mortality by COVID-19 in the Spanish population, its impact was analysed among persons with Cystic Fibrosis (CF) as a group at risk of a worse evolution. The possible causes of the incidence observed in them are explained and how CF Units have faced this health challenge is detailed., [Methods] Retrospective descriptive observational study, for which a Spanish CF Patients with Confirmed COVID-19 Registry is created, requesting information on number of people affected between 8 March–16 May 2020 and their clinical-demographic characteristics from the CF Units participating in the European Cystic Fibrosis Society Patient Registry (ECFSPR). The accumulated incidence is calculated, compared with that of the general population. Additionally, a survey (CF-COVID19-Spain) is carried out on prevention of SARS-CoV-2 infection, workings of CF Units and possible reasons for the incidence observed., [Results] COVID-19 was diagnosed in eight CF patients, one of whom had received a lung transplant. The accumulated incidence was 32/10000 in CF patients and 49/10000 in the general population. General death rate was 5.85/10000 while no CF patients included in the ECFSPR died. The characteristics of those affected and the results of the survey are described., [Conclusions] Despite being considered a disease at high risk of severe COVID-19, the low incidence and mortality in CF patients in Spain contrasts with the figures for the general population. The possible factors that would explain such findings are discussed, with the help of the results of the CF-COVID19-Spain survey.
