High-flow nasal cannula oxygen therapy for the treatment of acute respiratory failure secondary to SARS-CoV-2 pneumonia out of ICU.

Introduction And Objectives: High-flow nasal cannula oxygen therapy (HFNC) has been successfully used for the treatment of acute hypoxaemic respiratory failure (AHRF) secondary to SARS-CoV-2 pneumonia and being effective in reducing progression to invasive mechanical ventilation. The objective of this study was to assess the usefulness of HFNC on a hospital ward for the treatment of AHRF secondary to SARS-CoV-2 pneumonia and its impact on the need for intensive care unit (ICU) admission and endotracheal intubation. Other objectives include identifying potential physiological parameters and/or biomarkers for predicting treatment failure and assessing the clinical course and survival.

Short- and long-term prognosis of patients with community-acquired Legionella or pneumococcal pneumonia diagnosed by urinary antigen testing.

Objectives: To analyze the differences in short- and long-term prognosis and the predictors of survival between patients with community-acquired Legionella and Streptococcus pneumoniae pneumonia, diagnosed early by urinary antigen testing (UAT).

Methods: Prospective multicenter study conducted in immunocompetent patients hospitalized with community-acquired Legionella or pneumococcal pneumonia (L-CAP or P-CAP) between 2002-2020. All cases were diagnosed based on positive UAT.

Validation of IDSA/ATS Guidelines for ICU Admission in Adults Over 80 Years Old With Community-Acquired Pneumonia.

Introduction: The 2007 IDSA/ATS guidelines for community-acquired pneumonia (CAP) recommended intensive care unit (ICU) admission for adults meeting severe CAP criteria. We aimed to validate the accuracy of IDSA/ATS criteria in patients≥80 years old (very elderly patients, VEP) with CAP.

Methods: Prospective cohort study of VEP with CAP admitted to three Spanish hospitals between 1996 and 2019.

WITHDRAWN: Validation of IDSA/ATS Guidelines for ICU Admission in Adults Over 80 Years Old With Community-acquired Pneumonia.

Estimating the risk of bacteraemia in hospitalised patients with pneumococcal pneumonia.

Objective: To construct a prediction model for bacteraemia in patients with pneumococcal community-acquired pneumonia (P-CAP) based on variables easily obtained at hospital admission.

Methods: This prospective observational multicentre derivation-validation study was conducted in patients hospitalised with P-CAP between 2000 and 2020. All cases were diagnosed based on positive urinary antigen tests in the emergency department and had blood cultures taken on admission.

Evolution of serotypes in bacteremic pneumococcal adult pneumonia in the period 2001-2014, after introduction of the pneumococcal conjugate vaccine in bizkaia (spain).

The introduction of pneumococcal conjugate vaccines (PCV7 and PCV13) in children has led to a change in the pattern of pneumococcal serotypes causing pneumococcal disease in adults. The aim of this study is to analyze the distribution of pneumococcal serotypes in adults with bacteremic pneumococcal community-acquired pneumonia (BPP) after the introduction of PCVs in childhood, and the impact of age and comorbidity on this distribution. We conducted an observational study of all adults hospitalized with BPP between 2001 and 2014, in two tertiary hospitals.

Streptococcus pneumoniae antigen in urine: diagnostic usefulness and impact on outcome of bacteraemic pneumococcal pneumonia in a large series of adult patients.

Background And Objective: Urinary pneumococcal antigen detection provides good results in the diagnosis of pneumococcal pneumonia but has rarely been used in bacteraemic pneumococcal pneumonia and it is not known whether it is associated with outcome in this type of pneumonia. Our objectives were to assess the usefulness of an immunochromatographic technique for detecting the pneumococcal antigen in urine in a large prospective study of patients with bacteraemic pneumococcal pneumonia and explore any potential association with outcomes.

Methods: This study, carried out over 8 years, included all adult immunocompetent patients admitted for bacteraemic pneumococcal pneumonia.

Factors associated with hospital admission for exacerbation of chronic obstructive pulmonary disease.

Introduction: Exacerbations of Chronic Obstructive Pulmonary Disease (COPD) that require hospital admission have a major impact on the progression of disease and generate high health costs.

Method: A multi-center, cross-sectional, observational, study was conducted with the aim to identify factors associated with hospital admission in patients with COPD. We obtained data of socio-demographic and anthropometric characteristics, quality of life, respiratory symptoms, anxiety and depression, physical activity and pulmonary function tests.

Escherichia coli: an unknown and infrequent cause of community acquired pneumonia.

Our aim was to describe the incidence, clinical characteristics and outcome of community acquired pneumonia (CAP) caused by Escherichia coli through the analysis of a cohort of patients with this condition. This study includes all the patients who were admitted to our hospitals because of CAP caused by E. coli, diagnosed with highly reliable microbiological techniques, such as blood culture, bronchoscopic protected specimen brush (PSB) or transthoracic needle aspiration (TNA).
