    Background: emerging evidence links ambient air pollution with coronavirus 2019 (COVID-19) disease, an association that is methodologically challenging to investigate. Objectives: we examined the association between long-term ...
  • Determinants of early antibody responses to COVID-19 mRNA vaccines in a cohort of exposed and naïve healthcare workers
    Moncunill, Gemma; Aguilar, Ruth; Ribes, Marta; Ortega, Natalia; Rubio, Rocío; Molina, María José; Vidal, Marta; Barrios, Diana; Mitchell, Robert A.; Jiménez, Alfons; Castellana, Cristina; Rodó, Pau; Méndez, Susana; Llupià, Anna; Puyol, Laura; Rodrigo Melero, Natalia; Carolis, Carlo; Mayor, Alfredo; Izquierdo, Luis; Trilla, Antoni; Vilella, Anna; García-Basteiro, Alberto L.; Dobaño, Carlota (Elsevier, 2022)
    Background: Two doses of mRNA vaccination have shown >94% efficacy at preventing COVID-19 mostly in naïve adults, but it is not clear if the second dose is needed to maximize effectiveness in those previously exposed to ...
  • Individual blood concentrations of persistent organic pollutants and chemical elements, and COVID-19: A prospective cohort study in Barcelona
    Porta Serra, Miquel; Pumarega Rodríguez, José Antonio; Gasull Panadès, Magda; Aguilar, Ruth; Henríquez Hernández, Luis Alberto; Basagaña Flores, Xavier; Zumbado, Manuel; Villar García, Judit; Rius, Cristina; Mehta, Sneha; Vidal, Marta; Jiménez, Alfons; Campi, Laura; Lop Gros, Joan; Pérez Luzardo, Octavio L.; Dobaño, Carlota; Moncunill, Gemma (Elsevier, 2023)
    Background: There is wide, largely unexplained heterogeneity in immunological and clinical responses to SARS-CoV-2 infection. Numerous environmental chemicals, such as persistent organic pollutants (POPs) and chemical ...
  • Infection induced SARS-CoV-2 seroprevalence and heterogeneity of antibody responses in a general population cohort study in Catalonia Spain
    Karachaliou, Marianna; Moncunill, Gemma; Espinosa Díaz, Ana; Castaño Vinyals, Gemma; Jiménez, Alfons; Vidal, Marta; Santano, Rebeca; Barrios, Diana; Jiménez, Alfons; Puyol, Laura; Mayer, Leonie; Rubio, Rocío; O'Callaghan Gordo, Cristina; Fossati, Serena; Rivas, Ioar; Vrijheid, Martine; Izquierdo, Luis; Aguilar, Ruth; Basagaña Flores, Xavier; García Aymerich, Judith; Dobaño, Carlota; Kogevinas, Manolis (Nature Research, 2021)
    Sparse data exist on the complex natural immunity to SARS-CoV-2 at the population level. We applied a well-validated multiplex serology test in 5000 participants of a general population study in Catalonia in blood samples ...
  • Multiplex antibody analysis of IgM, IgA and IgG to SARS-CoV-2 in saliva and serum from infected children and their close contacts
    Dobaño, Carlota; Alonso, Selena; Vidal, Marta; Jiménez, Alfons; Rubio, Rocío; Santano, Rebeca; Barrios, Diana; Puyol, Laura; Baró, Bàrbara; Millat-Martínez, Pere; Ajanovic, Sara; Balanza, Núria; Arias, Sara; Rodrigo Melero, Natalia; Carolis, Carlo; Bassat, Quique; Izquierdo, Luis; Aguilar, Ruth; Moncunill, Gemma (Frontiers, 2022)
    COVID-19 affects children to a lesser extent than adults but they can still get infected and transmit SARS-CoV-2 to their contacts. Field deployable non-invasive sensitive diagnostic techniques are needed to evaluate the ...
  • Plasma MicroRNA profiling of Plasmodium falciparum biomass and association with severity of malaria disease
    Gupta, Himanshu; Rubio, Mercedes; Sitoe, Antonio; Varo, Rosauro; Cisteró, Pau; Madrid, Lola; Cuamba, Inocencia; Jiménez, Alfons; Martiáñez-Vendrell, Xavier; Barrios, Diana; Pantano Rubiño, Lorena, 1982-; Brimacombe, Allison; Bustamante Pineda, Mariona; Bassat, Quique; Mayor, Alfredo (Centers for Disease Control and Prevention, 2021)
    Severe malaria (SM) is a major public health problem in malaria-endemic countries. Sequestration of Plasmodium falciparum-infected erythrocytes in vital organs and the associated inflammation leads to organ dysfunction. ...
  • RBD-Based ELISA and luminex predict Anti-SARS-CoV-2 surrogate-neutralizing activity in two longitudinal cohorts of German and Spanish health care workers
    Aguilar, Ruth; Vidal, Marta; Rubio, Rocío; Jiménez, Alfons; Carolis, Carlo; Mayor, Alfredo; Izquierdo, Luis; Garcia Basteiro, Alberto L.; Moncunill, Gemma; Dobaño, Carlota; Gerhard, Markus (American Society for Microbiology, 2023)
    The ability of antibodies to neutralize severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is an important correlate of protection. For routine evaluation of protection, however, a simple and cost-efficient ...
  • SARS-CoV-2 infection, vaccination, and antibody response trajectories in adults: a cohort study in Catalonia
    Karachaliou, Marianna; Moncunill, Gemma; Espinosa Díaz, Ana; Castaño Vinyals, Gemma; Rubio, Rocío; Vidal, Marta; Jiménez, Alfons; Prados, Esther; Bañuls, Marc; Melero, Natalia Rodrigo; Izquierdo, Luis; Carolis, Carlo; Goldberg, Ximena; Aguilar, Ruth; García Aymerich, Judith; Kogevinas, Manolis; Dobaño, Carlota (BioMed Central, 2022)
    Background: Heterogeneity of the population in relation to infection, COVID-19 vaccination, and host characteristics is likely reflected in the underlying SARS-CoV-2 antibody responses. Methods: We measured IgM, IgA, and ...
