Association between early echocardiography screening of low systemic blood flow and intraventricular hemorrhage in preterm infants: a multicenter cohort study.

OBJECTIVE: To determine whether early echocardiography screening of low systemic blood flow reduces intraventricular hemorrhage in preterm infants. STUDY DESIGN: Prospective multicenter study in preterm infants below 33 weeks of gestational age at nine neonatal units. Five units performed early echocardiography screening for low systemic blood flow and guided clinical management (exposure group) and 4 units did not (control group). Our main outcome was ≥grade II intraventricular hemorrhage or death within the first 7 days of life. The main analysis used the inverse probability of treatment weighting. RESULTS: Three hundred and thirty-two preterm infants (131 in the exposure group and 201 in the control group) were included. Exposure to early echocardiography screening was associated with a significant reduction in ≥grade II intraventricular hemorrhage or early death [odds ratio 0.285 (95% CI: 0.133-0.611); p = 0.001]. CONCLUSIONS: Early echocardiography screening for low systemic blood flow may reduce the incidence of intraventricular hemorrhage in preterm infants.

Infecciones periamigdalinas en el área de salud de León los años previos a la pandemia, durante la misma y posterior a ella. Estudio de un periodo de 6 años / Trend of peritonsillar infections in the León Health Area in the years before, during and after the pandemic. Study of a 6-year period

Introducción y objetivo: La COVID-19 ha tenido diversas consecuencias para el sistema sanitario de salud. Centrándonos en nuestro Servicio de Otorrinolaringología, hemos observado un descenso en la aparición de infecciones periamigdalinas (IPA). El objetivo de este estudio es evaluar aspectos epidemiológicos de las IPA a lo largo de un período de 6 años. Método: Estudio descriptivo retrospectivo y longitudinal con datos obtenidos del registro hospitalario informatizado de León durante un período de 6 años. Resultados: Un total de 327 pacientes fueron incluidos, prepandemia 201 (61.47%), en pandemia 64 (19.54%) y postpandemia 62 (18.96%), con una disminución de 48.58% en la incidencia de IPA. Discusión: Encontramos resultados similares a los analizados en otras series sobre la incidencia de los abscesos periamigdalinos durante la pandemia, sin embargo, tenemos una mayor estancia media hospitalaria en los ingresos por dicha patología. Conclusiones: La pandemia ha repercutido y cambiado la forma de atender ciertas patologías. En nuestro caso, en lo referente a los abscesos periamigdalinos observamos un claro descenso. (AU)

Introduction and objective: COVID-19 has had various consequences for the health care system. Focusing on our ENT Service, we have observed a decrease in the occurrence of peritonsillar infections (PTI). The aim of this study is to evaluate epidemiological aspects of PTIs over a 6-year period. Method: Retrospective and longitudinal descriptive study with data obtained from the computerized hospital registry of León over a 6-year period. Results: A total of 327 patients were included, pre-pandemic 201 (61.47%), pandemic 64 (19.54%) and post-pandemic 62 (18.96%), with a decrease of 48.58% in the incidence of IPA. Discussion: We found similar results to those analyzed in other series about the incidence of peritonsillar abscesses during the pandemic, however, we have a longer mean hospital stay in admissions for this pathology. Conclusions: The pandemic has affected and changed the way we look at certain conditions. In our case, when looking at peritonsillar abscesses we have observed a clear decrease. (AU)
