[All Roads Lead to Rome: Results of Non-Invasive Respiratory Therapies Applied in a Tertiary-Care Hospital Without an Intermediate Care Unit During the COVID-19 Pandemic].

Introduction: Non-invasive respiratory therapies (NRT) were widely used in the first wave of the COVID-19 pandemic in different settings, depending on availability. The objective of our study was to present 90-day survival and associated factors in patients treated with NRT in a tertiary hospital without an Intermediate Respiratory Care Unit. The secondary objective was to compare the outcomes of the different therapies.

Influence of Comorbidities on the Survival of COPD Patients According to Phenotypes.

Background: Chronic obstructive pulmonary disease (COPD) usually occurs alongside other conditions. Few studies on comorbidities have taken into account the phenotypes of COPD patients. The objective of this study is to evaluate the prevalence of comorbidities included in the Charlson index and their influence on the survival of patients with COPD, taking phenotypes into account.

Gender Differences in Original Archivos de Bronconeumología Publications, 2001-2018.

Introduction: Gender inequality exists in scientific publications. The aim of this study was to determine changing patterns in gender differences and factors associated with the positioning of authors' names in original articles published in Archivos de Bronconeumología (AB).

Methods: We performed a bibliometric study of articles published in AB between 2001 and 2018.

Differences in the Outcome of Patients with COPD according to Body Mass Index.

Background: In chronic obstructive pulmonary disease (COPD), the "obesity paradox" is a phenomenon without a clear cause. The objective is to analyze the complications of COPD patients according to their body mass index (BMI).

Methods: An observational study with a six-year prospective follow-up of 273 COPD patients who attended a spirometry test in 2011.

Influence of Pneumonia on the Survival of Patients with COPD.
