MicroRNAs (miRNAs) have a crucial role in regulating immune response against infectious diseases, showing changes early disease onset and before the detection of pathogen. Thus, we aimed to analyze plasma miRNA profile at COVID-19 identify miRNAs as prognostic biomarkers severity survival.Plasma miRNome 96 patients that developed asymptomatic/mild, moderate severe was sequenced together with group healthy controls. Plasma immune-related were also assessed. showed 200 significant...

This study aimed to investigate the association of baseline coagulation proteins with hospitalization variables in COVID-19 patients admitted ICU, as well system changes after one-year post-discharge, taking into account gender-specific bias profile. We conducted a prospective longitudinal on 49 ICU-admitted patients. Proteins were measured using Luminex 200™. The between protein levels and was carried out by generalized linear models adjusted most relevant covariates. At ICU admission,...

Abstract Background Information is lacking regarding long-term survival and predictive factors for mortality in patients with acute hypoxemic respiratory failure due to coronavirus disease 2019 (COVID-19) undergoing invasive mechanical ventilation. We aimed estimate 180-day of COVID-19 requiring ventilation, develop a model mortality. Methods Retrospective, multicentre, national cohort study between March 8 April 30, 2020 16 intensive care units (ICU) Spain. Participants were consecutive...

Background metabolic changes through SARS-CoV-2 infection has been reported but not fully comprehended. This dysregulation affects multiple organs during COVID-19 and its early detection can be used as a prognosis marker of severity. Therefore, we aimed to characterize cytokine profile at onset relationship with disease severity identify profiles predicting progression. Material Methods performed retrospective cross-sectional study in 123 patients which were stratified asymptomatic/mild,...

In recent years, medical practice has followed two different paradigms: evidence-based medicine (EBM) and values-based (VBM). There is an urgent need to promote education that strengthens the relationship between these paradigms. This work designed establish foundations for a continuing (CME) program aimed at encouraging dialogue EBM VBM by determining values relevant everyday activities. A quasi-experimental, observational, comparative, prospective qualitative study was conducted analyzing...

Background/Objectives: The COVID-19 pandemic resulted in 675 million cases and 6.9 deaths by 2022. Despite substantial declines case fatalities following widespread vaccination campaigns, the threat of future coronavirus outbreaks remains a concern. Current treatments for have been repurposed from existing therapies other infectious non-infectious diseases. Emerging evidence suggests role genetic factors both susceptibility to SARS-CoV-2 infection response treatment. However, comprehensive...

Background: Acute myocardial infarction (AMI) with no evidence of relevant stenosis the coronary artery, known as (MI) nonobstructive arteries (MINOCA), has a prevalence up to 14%. The various causes MINOCA lead damage myocardium, and there are marked differences in diagnoses, prognoses, treatments. Although number patients affected is considerable owing high acute syndrome (ACS), have received little attention result that some may not receive appropriate treatment. Awareness this disease...

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes virus-induced-senescence. There is an association between shorter telomere length (TL) in disease 2019 (COVID-19) patients and hospitalization, severity, or even death. However, it remains unknown whether virus-induced-senescence reversible. We aim to evaluate the dynamics of TL COVID-19 1 year after recovery from intensive care units (ICU). Longitudinal study enrolling 49 admitted ICU due (August 2020 April 2021). Relative...
