  • A semi-empirical risk panel to monitor epidemics

    Open AccessAida Perramon-Malavez, Aida Perramon‐Malavez et al.ARTICLEFrontiers in Public Health2024

    Introduction Bronchiolitis, mostly caused by Respiratory Syncytial Virus (RSV), and influenza among other respiratory infections, lead to seasonal saturation at healthcare centers in temperate areas. There is no gold standard to characterize the stages of epidemics, nor the risk of respiratory infections growing. We aimed to define a set of indicators to assess the risk level of respiratory viral epidemics, based on both incidence and their short…

  • Mathematical modeling of Sars-CoV-2 variant substitutions in European countries

    Open AccessVíctor López de Rioja, Aida Perramon-Malavez et al.ARTICLEFrontiers in Public Health2024

    Background Countries across Europe have faced similar evolutions of SARS-CoV-2 variants of concern, including the Alpha, Delta, and Omicron variants. Materials and methods We used data from GISAID and applied a robust, automated mathematical substitution model to study the dynamics of COVID-19 variants in Europe over a period of more than 2 years, from late 2020 to early 2023. This model identifies variant substitution patterns and distinguishes …

  • Transmissibility, hospitalization, and intensive care admissions due to omicron compared to delta variants of Sars-CoV-2 in Catalonia

    Open AccessMartí Català, Ermengol Coma et al.ARTICLEFrontiers in Public Health2022

    Purpose: We aim to compare the severity of infections between omicron and delta variants in 609,352 SARS-CoV-2 positive cases using local hospitalization, vaccination, and variants data from the Catalan Health Care System (which covers around 7. 8 million people). Methods: We performed a substitution model to establish the increase in transmissibility of omicron using variant screening data from primary care practices (PCP) and hospital admission…

  • Risk Diagrams Based on Primary Care Electronic Medical Records and Linked Real-Time PCR Data to Monitor Local Covid-19 Outbreaks During the Summer 2020

    Open AccessMartí Català, Ermengol Coma et al.ARTICLEFrontiers in Public Health2021

    Monitoring transmission is a prerequisite for containing COVID-19. We report on effective potential growth (EPG) as a novel measure for the early identification of local outbreaks based on primary care electronic medical records (EMR) and PCR-confirmed cases. Secondly, we studied whether increasing EPG precedes local hospital and intensive care (ICU) admissions and mortality. Population-based cohort including all Catalan citizens' PCR tests, hosp…

  • Monitoring and Analysis of Covid-19 Pandemic

    Open AccessMartí Català, Miquel Marchena et al.ARTICLEFrontiers in Public Health2021

    The current worldwide pandemic produced by coronavirus disease 2019 (COVID-19) has changed the paradigm of mathematical epidemiology due to the high number of unknowns of this new disease. Thus, the empirical approach has emerged as a robust tool to analyze the actual situation carried by the countries and also allows us to predict the incoming scenarios. In this paper, we propose three empirical indexes to estimate the state of the pandemic. The…

  • Secaba-Rank, herramienta online para analizar y evaluar bibliotecas

    Open AccessPedro Lázaro-Rodríguez, Javier López Gijón et al.ARTICLEEl Profesional de la Informacion2018References: 3

    Secaba-Rank is an online tool that includes Secaba-Rank Universitarias and Secaba-Rank Publicas, which can be used to evaluate both Spanish university libraries and public reading networks. Using a systemic approach, the methodology makes use of second level indicators focused on efficiency. This methodology facilitates the benchmarking of libraries to find models of good practice in order to improve. Secaba-Rank is an essential tool for decision…

  • Agregación de índices bibliométricos para evaluar la producción científica de los investigadores

    Open AccessFrancisco Herrera, Enrique Herrera-Viedma et al.ARTICLEEl Profesional de la Informacion2009Cited by: 2

    In this paper we show that the aggregation of bibliometric indices is an appropriate way to evaluate scientific production of researchers because it allows us to develop much more precise new bibliometric indices that combine the advantages of each index that is aggregated
