    Network-based approaches are becoming increasingly popular for drug discovery as they provide a systems-level overview of the mechanisms underlying disease pathophysiology. They have demonstrated significant early promise ...
  • A model of checkpoint behavior for applications that have I/O 

    León, Betzabeth; Méndez, Sandra; Franco, Daniel; Rexachs, Dolores; Luque, Emilio (Springer, 2022-04)
    Article
    Open Access
    Due to the increase and complexity of computer systems, reducing the overhead of fault tolerance techniques has become important in recent years. One technique in fault tolerance is checkpointing, which saves a snapshot ...
  • Pulmonary function and radiologic features in survivors of critical COVID-19: a 3-month prospective cohort

    Article
    Open Access
    BACKGROUND: More than 20% of hospitalized patients with COVID-19 demonstrate ARDS requiring ICU admission. The long-term respiratory sequelae in such patients remain unclear. RESEARCH QUESTION: What are the major long-term ...
  • ICU-Acquired Pneumonia Is Associated with Poor Health Post-COVID-19 Syndrome 

    Martin-Loeches, Ignacio; Motos, Anna; Menéndez, Rosario; Gabarrús, Albert; González, Jessica; Pérez-Arnal, Raquel; Garcia Gasulla, Dario (MDPI, 2021-12)
    Article
    Open Access
    Background. Some patients previously presenting with COVID-19 have been reported to develop persistent COVID-19 symptoms. While this information has been adequately recognised and extensively published with respect to ...
  • Impact of time to intubation on mortality and pulmonary sequelae in critically ill patients with COVID-19: a prospective cohort study 

    González Gutiérrez, Jessica; Benítez Iglesias, Iván D.; de Gonzalo Calvo, David; Torres Cortada, Gerard; Batlle, Jordi de; Gómez Falguera, Silvia; Moncusí Moix, Anna; Carmona, Paola; Santisteve, Sallya; Gort Paniello, Clara; Ferrer Roca, Ricard; Garcia Gasulla, Dario; Torres, Antoni; Barbé, Ferran; Monge Esqué, Aida; Zuil Moreno, María (Springer Nature, 2022-12)
    Article
    Open Access
    We evaluated whether the time between first respiratory support and intubation of patients receiving invasive mechanical ventilation (IMV) due to COVID-19 was associated with mortality or pulmonary sequelae. Materials and ...
  • Large scale prediction of sick leave duration with nonlinear survival analysis algorithms 

    Béjar Alonso, Javier; Pérez Arnal, Raquel Leandra; Vilalta, Armand; Álvarez Napagao, Sergio; García Gasulla, Dario (2022-07-15)
    Article
    Restricted access - publisher's policy
    The management of sick leaves is a critical task that public and private health systems carry out. This enables the good care of sick workers and guarantees a safe return to their jobs. Most health systems enforce regulations ...
