Abstract Background COVID-19 can course with respiratory and extrapulmonary disease. SARS-CoV-2 RNA is detected in samples but also blood, stool urine. Severe characterized by a dysregulated host response to this virus. We studied whether viral RNAemia or load plasma associated severe response. Methods A total of 250 patients were recruited (50 outpatients, 100 hospitalized ward critically ill). Viral detection quantification was performed using droplet digital PCR, targeting the N1 N2...

Non-alcoholic fatty liver disease (NAFLD) is characterised by an excess of hepatic fat that can progress to steatohepatitis, fibrosis, cirrhosis and hepatocarcinoma. The imbalance between lipid uptake/lipogenesis oxidation/secretion in the a major feature NAFLD. Given lack non-invasive reliable methods for diagnosis non-alcoholic steatohepatitis (NASH), it important find serum markers are capable discriminating or defining patients with this stage NASH. Blood samples were obtained from 152...

Background: Intensive care unit-acquired pneumonia (ICU-AP) is a severe complication in patients admitted to the ICU. Lymphocytopenia marker of poor prognosis with community-acquired pneumonia, but its impact on ICU-AP unknown. We aimed evaluate whether lymphocytopenia an independent risk factor for mortality non-immunocompromised ICU-AP. Methods: Prospective observational cohort study from six ICUs 800-bed tertiary teaching hospital (2005 2016). Results: Of 473 included, 277 (59%) had...

Community-acquired pneumonia (CAP) is a frequent cause of death worldwide. As recently described, CAP shows different biological endotypes. Improving characterization these endotypes needed to optimize individualized treatment this disease. The potential value the leukogram assist prognosis in severe has not been previously addressed.A cohort 710 patients with admitted intensive care units (ICUs) at Hospital Mataró and Parc Taulí Sabadell was retrospectively analyzed. Patients were split...

Abstract Background Stratification of the severity infection is currently based on Sequential Organ Failure Assessment (SOFA) score, which difficult to calculate outside ICU. Biomarkers could help stratify in surgical patients. Methods Levels ten biomarkers indicating endothelial dysfunction, 22 emergency granulopoiesis, and six denoting neutrophil degranulation were compared three groups patients first 12 h after diagnosis at Spanish hospitals. Results There 100 with infection, 95 sepsis 57...

Abstract Background Despite growing interest in treatment strategies that limit oxygen exposure ICU patients, no studies have compared conservative with standard postsurgical patients sepsis/septic shock, although there are indications it may improve outcomes. It has been proven high partial pressure of arterial blood (PaO 2 ) reduces the rate surgical-wound infections and mortality under major surgery. The aim this study is to examine whether PaO associated risk death adult shock after...

Introduction Prevalence and mortality of the acute respiratory distress syndrome (ARDS) in intensive care units (ICU) are unacceptably high. There is scarce literature on post-operative sepsis-induced ARDS despite that sepsis major surgery conditions associated with ARDS. We aimed to examine impact 60-day mortality. Methods performed a secondary analysis prospective observational study 454 patients who underwent admitted into single ICU. Patients were stratified two groups depending whether...

Diagnosing septic shock promptly is essential but challenging, especially due to its clinical similarity non-septic shock. Extracellular vesicle-derived miRNAs may serve as biomarkers distinguish from shock, providing a more accurate diagnostic tool for postsurgical patients. This study aims identify extracellular miRNA signatures that differentiate in patients, potentially improving accuracy and decision-making. A multicentre, prospective was conducted on profiles Two cohorts were recruited...

Despite the high mortality and economic burden associated with acute respiratory distress syndrome (ARDS), role of chest radiograph (CXR) in ARDS diagnosis prognosis remains uncertain. The purpose this study is to elucidate clinical characteristics that distinguish patients from those without ARDS, especially where CXRs are indicative ARDS. Secondary analysis a prospective observational 454 postoperative septic under mechanical ventilation (MV). Patients were stratified two groups depending...

Following the SEPSIS-3 consensus, detection of organ failure as assessed by SOFA (Sequential Organ Failure Assessment) score, is mandatory to detect sepsis. Calculating outside Intensive Care Unit (ICU) challenging. The alternative in this scenario, quick SOFA, very specific but less sensible. Biomarkers could help presence secondary infection either ICU and non-ICU settings.We evaluated ability four biomarkers (C-Reactive protein (CRP), lactate, mid-regional proadrenomedullin (MR-proADM)...

Antigen tests or polymerase chain reaction (PCR) amplification are currently COVID-19 diagnostic tools. However, developing complementary diagnosis tools is mandatory. Thus, we performed a plasma cytokine array in patients to identify novel biomarkers. A discovery–validation study two independent prospective cohorts was performed. The discovery cohort included 136 and non-COVID-19 recruited consecutively from 24 March 11 April 2020. Forty-five cytokines’ quantification by the MAGPIX system...
