Lower respiratory tract infections (LRTI) are the most frequent infectious complication in patients admitted to intensive care unit (ICU). We aim report clinical characteristics of ICU-admitted due nosocomial LRTI and describe their microbiology outcomes.A prospective observational study was conducted 13 countries over two continents from 9th May 2016 until 16th August 2019. Characteristics outcomes ventilator-associated pneumonia (VAP), tracheobronchitis (VAT), ICU hospital-acquired...

Latin American countries deeply affected, there is a lack of data in this regard. This study aims to identify clinical characteristics, in-hospital outcomes, factors associated with ICU admission due COVID-19. Furthermore, describe functional status patients at hospital discharge after acute episode Material methods was prospective, multicenter, multinational observational...

Abstract Around one-third of patients diagnosed with COVID-19 develop a severe illness that requires admission to the Intensive Care Unit (ICU). In clinical practice, clinicians have learned admitted ICU due frequently ventilator-associated lower respiratory tract infections (VA-LRTI). This study aims describe characteristics, factors associated VA-LRTI, and its impact on outcomes in COVID-19. was multicentre, observational cohort conducted ten countries Latin America Europe. We included...

Up to 30% of patients admitted hospitals with invasive pneumococcal disease (IPD) experience major adverse cardiovascular event (MACE) including new/worsening heart failure, arrhythmia, and/or myocardial infarction. Streptococcus pneumoniae (Spn) is the most frequently isolated bacterial pathogen among community-acquired pneumonia (CAP) and only etiological agent linked independently MACE. Nevertheless, no clinical data exist identifying which serotypes Spn are principally responsible for...

Patients with community-acquired pneumonia (CAP) admitted to the intensive care unit (ICU) have high mortality rates during acute infection and up ten years thereafter. Recommendations from international CAP guidelines include macrolide-based treatment. However, there is no data on long-term outcomes of this recommendation. Therefore, we aimed determine impact therapy in population.Registered patients MIMIC-IV database 16 or older ICU due were included. Multivariate analysis, targeted...

Background: Nosocomial lower respiratory tract infections (nLRTIs) are associated with unfavorable clinical outcomes and significant healthcare costs. nLRTIs include hospital-acquired pneumonia (HAP), ventilator-associated (VAP), other ICU-acquired phenotypes. While risk factors for mortality in these critical to guide preventive strategies, it remains unclear whether they vary based on their requirement of invasive mechanical ventilation (IMV) at any point during the hospitalization....

Abstract Background Nosocomial low respiratory infections (nLRTIs) represent a significant complication prevalent among patients who require admission to the intensive care unit (ICU). Gram-negative microorganisms are related nLRTIs, such as ventilator-associated pneumonia (VAP), tracheobronchitis (VAT), ICU-acquired (ICU-HAP), and hospital-acquired (HAP). Pseudomonas aeruginosa (PA) is frequently identified nLRTIs; however, not all with nLRTI may antipseudomonal treatment this clear in...

Abstract Background Microorganisms causing healthcare-associated infections are usually difficult to treat Gram-negative bacteria, making the empiric antibiotic selection challenging. Pseudomonas aeruginosa (PA) is a microorganism associated with hospital-acquired infections, and its rate of antimicrobial resistance has increased in last ten years. However, international prevalence P. ICU-Related Respiratory Infections (ICU-RRI) unknown. This study aims bridge this gap literature using...

Purpose Streptococcus pneumoniae (Spn ) is the primary bacterial cause of lower respiratory tract infections (LRTI) globally, particularly impacting older adults and children. While Spn colonization in children linked to LRTI, its prevalence, consequences with comorbidities remain uncertain. This study aims provide novel data that regard. Methods prospective outpatient chronic diseases was conducted Colombia. Data on demographics, vaccination, clinical history collected a RedCap database....

<title>Abstract</title> Rationale: Ventilator-associated pneumonia (VAP) is a common complication in patients under invasive mechanical ventilation (IMV), yet its underlying mechanisms remain poorly understood. This study investigated the lung microbiome, inflammatory response, and metabolism undergoing IMV to identify factors that may predispose them developing VAP. Objectives: To investigate how changes microbiome composition, metabolic profiles develop Methods: Patients requiring for at...

Abstract Background Inflammatory responses contribute to tissue damage in COVID-19 and community-acquired pneumonia (CAP). Although predictive values of different inflammatory biomarkers have been reported both, similarities differences profiles between these conditions remain uncertain. Therefore, we aimed determine the CAP, their association with clinical outcomes. Methods We report a prospective observational cohort study; conducted reference hospital Latin America.
