Dynamic Trajectories of Left Ventricular Ejection Fraction in Heart Failure
Josep Lupón,Giovana Gavidia-Bovadilla,Elena Ferrer,Marta de Antonio,Alexandre Perera-Lluna,Jorge López-Ayerbe,Mar Domingo,Julio Núñez,Elisabet Zamora,Pedro Moliner,Patricia Díaz-Ruata,Javier Santesmases,Antoni Bayes-Genis +12 more
TL;DR: LVEF trajectories vary in HF depending on a number of disease modifiers, but an inverted U-shaped pattern with lower LVEF at both ends of the distribution emerged, which was associated with higher mortality.
Journal ArticleDOI
eRah: A Computational Tool Integrating Spectral Deconvolution and Alignment with Quantification and Identification of Metabolites in GC/MS-Based Metabolomics
Xavier Domingo-Almenara,Jesus Brezmes,Maria Vinaixa,Sara Samino,Noelia Ramírez,Marta Ramon-Krauel,Carles Lerin,Marta Díaz,Lourdes Ibáñez,Xavier Correig,Alexandre Perera-Lluna,Oscar Yanes +11 more
TL;DR: The automated capabilities of eRah are demonstrated by the analysis of GC-time-of-flight (TOF) MS data from plasma samples of adolescents with hyperinsulinaemic androgen excess and healthy controls, and the quantitative results are compared to centWave, the peak-picking algorithm implemented in the widely used XCMS package, MetAlign, and ChromaTOF software.
Journal ArticleDOI
Applying learning analytics to students' interaction in business simulation games. The usefulness of learning analytics to know what students really learn
TL;DR: The usefulness of learning analytics tools are revealed to gain a more wide and holistic view of the learning process of students, discovering new aspects that affect students’ learning results.
Journal ArticleDOI
FELLA: an R package to enrich metabolomics data.
Sergio Picart-Armada,Sergio Picart-Armada,Francesc Fernandez-Albert,Francesc Fernandez-Albert,Maria Vinaixa,Oscar Yanes,Alexandre Perera-Lluna,Alexandre Perera-Lluna +7 more
TL;DR: The R package FELLA is introduced, an R package to perform a network-based enrichment of a list of affected metabolites, based on a knowledge graph representation of the KEGG database that focuses on interpretability.
Journal ArticleDOI
Heart Failure With Preserved Ejection Fraction Infrequently Evolves Toward a Reduced Phenotype in Long-Term Survivors.
Josep Lupón,Giovana Gavidia-Bovadilla,Elena Ferrer,Marta de Antonio,Alexandre Perera-Lluna,Alexandre Perera-Lluna,Jorge López-Ayerbe,Mar Domingo,Julio Núñez,Julio Núñez,Elisabet Zamora,Pedro Moliner,Evelyn Santiago-Vacas,Javier Santesmases,Antoni Bayes-Genis +14 more
TL;DR: LVEF remained ≥50% in the majority of patients with HFpEF for 11 years and no significant relationship was found between LVEF dynamics in the immediate preceding period and mortality.
