Incremento de infecciones respiratorias agudas graves en niños durante la última etapa de la pandemia COVID-19 / Increase in severe acute respiratory infections in children during the last phase of the COVID-19 pandemic

Objetivo. La pandemia COVID-19 ha causado una variación en la circulación de otros patógenos respiratorios. Nuestro objetivo fue analizar la epidemiología de las infecciones respiratorias agudas graves (IRAG) en niños durante 3 años de pandemia COVID-19, en comparación con un período previo de la misma dimensión temporal. Pacientes y métodos. Estudio observacional, realizado en un hospital terciario de España, que analizó la frecuencia y características de pacientes ingresados por IRAG en la Unidad de Cuidados Intensivos Pediátricos (UCIP) durante la pandemia COVID-19 (1 marzo-2020 a 28 de febrero-2023), en relación a un período pre-pandemia (1 marzo-2017 a 29 febrero-2020). Resultados. Se incluyeron 268 pacientes (59,6% varones). La mediana de edad fue 9,6 meses (RIQ 1,7 – 37). En el período pre-pandemia hubo 126 ingresos con una media de 42 admisiones/año. Durante la pandemia se produjeron 142 ingresos, observándose una reducción significativa de admisiones en el primer año (12 ingresos/año), en contraste con 82 ingresos durante el tercer año, que representó un incremento del 95% respecto a la media de admisiones/año en pre-pandemia. Además, en el último año se evidenció un incremento de coinfecciones virales en relación al período prepandemia (54,9% vs 39,7%; p=0,032). No hubo diferencias en días de hospitalización, ni estancia en UCIP. Conclusiones. Durante el último año, coincidiendo con bajas tasas de hospitalización por COVID en España, observamos un notable incremento de ingresos en la UCIP por IRAG por otras causas. Probablemente, el período prolongado de baja exposición a patógenos por las medidas adoptadas durante la pandemia, ha provocado una disminución de la inmunidad poblacional con un repunte de infecciones respiratorias.

Objective. The COVID-19 pandemic has caused a variation in the circulation of respiratory pathogens. Our aim was to analyze the epidemiology of severe acute respiratory infections (SARI) in children during 3 years of the COVID-19 pandemic, in comparison with a previous period. Patients and Methods. An observational study was conducted in a tertiary hospital in Spain, which analyzed the frequency and characteristics of patients admitted for SARI in the Pediatric Intensive Care Unit (PICU) during the COVID-19 pandemic (1 March 2020 to 28 February 2023), compared to pre-pandemic period (1 March 2017 to 29 February 2020). Results. A total of 268 patients were included (59.6% males). The median age was 9.6 months (IQR 1.7 – 37). In the pre-pandemic period, there were 126 admissions with an average of 42 admissions/year. During the pandemic, there were 142 admissions, observing a significant reduction in admissions in the first year (12 admissions/year), in contrast to 82 admissions during the third year, which represented an increase of 95% compared to the average of admissions/year in pre-pandemic. In addition, in the last year there was evidence of an increase in viral coinfections in relation to pre-pandemic period (54.9% vs 39.7%; p=0.032). There were no differences in length of hospital stay or PICU stay. Conclusions. During the last year, coinciding with low rates of hospitalization for COVID in Spain, we observed a notable increase in admissions to the PICU for SARI. Probably, the prolonged period of low exposure to pathogens due to the measures adopted during the pandemic might have caused a decrease in population immunity with a rise in severe respiratory infections.

Differences in incidence and survival to childhood cancer between rural and urban areas in Castilla y León, Spain (2003-2014): A Strobe-compliant study.

The aim of this study is to describe childhood cancer incidence and survival in Castilla y León (Spain) for the period 2003 to 2014 and to explore differences between rural and urban areas.We made a cohort study in the childhood population of our region for the period of years referred before. Age-adjusted incidence rates to the world standard population (ASRw) were calculated by direct method, and their comparisons were made using incidence rate rations. Survival proportions were calculated by Kaplan-Meier method and their comparisons with log-rank test. The median childhood population less than 15 years old was 296,776 children. A total of 615 cases were recorded from the population-based Childhood Cancer Registry, including all malignant and benign tumors of the central nervous system.Age-standardized incidence rates for all cancers were 176.6 per million. Leukemia incidence rates were highest in rural areas (51.08/million) than in urban areas (33.65/million; P = .018), and by age groups; these differences only remained at age 0 to 4 years with higher rural leukemia incidence (67.13/million) than in urban areas (39.32/million; P = .05). There were no statistically significant differences between rural and urban areas for lymphomas, central nervous system, and all other malignant solid tumors grouped. The 5-year overall survival rate for all patients was 84%, similar to other developed countries, with greater survival in rural areas (88%) compared with urban areas (80%; P = .033). The analysis by tumor groups showed a greater survival rate in rural areas for all the groups, although these differences only reached statistical significance in the group of leukemias, with a survival rate of 90% for rural areas compared with 76% for urban areas (P = .01). Analyzing survival rate by age groups in leukemias only significant survival differences at 10 to 14 years were encountered.We found a higher incidence of leukemia in girls, mainly in rural areas, and also a better survival rate in children diagnosed with leukemia belonging to this population area. Future studies that analyze these facts in similar populations can help us clarify what genetic, epigenetic and environmental factors influence our population and are responsible for these findings.
