Antifibrotic treatment adherence, efficacy and outcomes for patients with idiopathic pulmonary fibrosis in Spain: a real-world evidence study.

Background: Idiopathic pulmonary fibrosis (IPF) is a rare disorder associated with increased mortality and morbidity. There are currently two drugs approved for IPF but their safety and efficacy profile in real-world settings in Spain is not well understood.

Methods: An observational, multicentre, prospective study was carried out among patients with IPF who started treatment with pirfenidone or nintedanib from 2015 to 2021.

Persistent Respiratory Failure and Re-Admission in Patients with Chronic Obstructive Pulmonary Disease Following Hospitalization for COVID-19.

Background: Chronic obstructive pulmonary disease (COPD) has been associated with worse clinical evolution/survival during a hospitalization for SARS-CoV2 (COVID-19). The objective of this study was to learn the situation of these patients at discharge as well as the risk of re-admission/mortality in the following 12 months.

Methods: We carried out a subanalysis of the RECOVID registry.

Prospective study to evaluate quality of life in amyotrophic lateral sclerosis.

Amyotrophic lateral sclerosis (ALS) is a neurodegenerative rare disease characterized by symptoms and signs in the upper and lower motor neurons, leading to progressive neuro-degeneration and muscle atrophy. Our objective was to analyse the quality of life (QoL) in patients with ALS and compare with general population and with patients with cancer. Prospective study from consecutive ALS patients in one center.

Spike protein of SARS-CoV-2 Omicron variant: An study evaluating spike interactions and immune evasion.

Background: The fundamentals of the infectivity and immune evasion of the SARS-CoV-2 Omicron variant are not yet fully understood. Here, we carried out an study analyzing the spike protein, the protein electrostatic potential, and the potential immune evasion.

Methods: The analysis was based on the structure of the spike protein from two SARS-CoV-2 variants, the original Wuhan and the Botswana (Omicron).

A Comparative Study between Spanish and British SARS-CoV-2 Variants.

The study of the interaction between the SARS-CoV-2 spike protein and the angiotensin-converting enzyme 2 (ACE2) receptor is key to understanding binding affinity and stability. In the present report, we sought to investigate the differences between two already sequenced genome variants (Spanish and British) of SARS-CoV-2. In silico model evaluating the homology, identity and similarity in the genome sequence and the structure and alignment of the predictive spike by computational docking methods.

Effectiveness of aprepitant in post-acute COVID19 syndrome.

This is the first case of a patient taking aprepitant for a post-acute COVID-19 syndrome. This case may encourage researchers to look for the evidence for the efficacy and safety of a neurokinin 1 receptor antagonist in this frequent syndrome.

Lung Function, Radiological Findings and Biomarkers of Fibrogenesis in a Cohort of COVID-19 Patients Six Months After Hospital Discharge.

Introduction: Impairment in pulmonary function tests and radiological abnormalities are a major concern in COVID-19 survivors. Our aim is to evaluate functional respiratory parameters, changes in chest CT, and correlation with peripheral blood biomarkers involved in lung fibrosis at two and six months after SARS-CoV-2 pneumonia.

Methods: COVID-FIBROTIC (clinicaltrials.

Evaluation of lung parenchyma, blood vessels, and peripheral blood lymphocytes as a potential source of acute phase reactants in patients with COPD.

Previous studies have shown that the arterial wall is a potential source of inflammatory markers in COPD. Here, we sought to compare the expression of acute phase reactants (APRs) in COPD patients and controls both at the local (pulmonary arteries and lung parenchyma) and systemic (peripheral blood leukocytes and plasma) compartments. Consecutive patients undergoing elective surgery for suspected primary lung cancer were eligible for the study.

Causes of Pulmonary Fibrosis in the Elderly.

Idiopathic pulmonary fibrosis (IPF) is the most common and most lethal type of idiopathic interstitial pneumonia. It is a chronic, aging-associated lung disease characterized by fibrotic foci and inflammatory infiltrates, with no cure and very limited therapeutic options. Although its etiology is unknown, several pathogenic pathways have been described that could explain this process, involving aging, environmental factors, genomic instability, loss of proteostasis, telomere attrition, epigenetic changes, mitochondrial dysfunction, cell senescence, and altered intercellular communication.

Evaluation of clinical variables according to follow-up times in COPD: results from ON-SINT cohort.

: COPD is a chronic disease traditionally associated with increased symptoms as lung function deteriorates. Follow-up times in previous cohort studies were limited to a few years. Interestingly, newer longer observational studies show a more comprehensive picture on disease progression over time.

Occupational and Biomass Exposure in Chronic Obstructive Pulmonary Disease: Results of a Cross-Sectional Analysis of the On-Sint Study.

Background: Although tobacco smoke is the main risk factor for chronic obstructive pulmonary disease (COPD), other inhaled toxics have also been associated with the disease. The present study analyzes data from exposure to these substances in a cohort of patients with COPD and assesses their impact on the clinical presentation of the disease.

Methods: This is a cross-sectional analysis of the Clinical presentation, diagnosis and course of chronic obstructive pulmonary disease (On-Sint) study.

Cigarette Smoke Decreases the Maturation of Lung Myeloid Dendritic Cells.

Background: Conflicting data exist on the role of pulmonary dendritic cells (DCs) and their maturation in patients with chronic obstructive pulmonary disease (COPD). Herein, we investigated whether disease severity and smoking status could affect the distribution and maturation of DCs in lung tissues of patients undergoing elective pneumectomy or lobectomy for suspected primary lung cancer.

Materials And Methods: A total of 75 consecutive patients were included.

Implications of the inflammatory response for the identification of biomarkers of chronic obstructive pulmonary disease.

Chronic obstructive pulmonary disease (COPD) is characterized by both local and systemic inflammation. Because inflammation plays a critical role in the development, course and severity of COPD, inflammatory markers have the potential to improve the current diagnostic and prognostic approaches. Local inflammation in COPD is characterized by an infiltration of inflammatory cells, with an increased expression of cytokines, chemokines, enzymes, growth factors and adhesion molecules.

Evaluation of the visit frequency and the use of questionnaires and indices for COPD: a national survey from the On-Sint study.

Introduction: Despite widespread recommendations to use standardized questionnaires and multidimensional indices for the assessment of patients with chronic obstructive pulmonary disease (COPD), few data are available on the application of these tools in clinical practice. This study evaluates the attitude of physicians participating in the On-Sint cohort toward the use of health status questionnaires and multidimensional indices, as well as toward the frequency of visits and spirometry in primary care and specialized care.

Methods: During the constitution of the On-Sint cohort, the participating physicians were surveyed about their clinical practice.

Evaluation of the COPD Assessment Test and GOLD patient types: a cross-sectional analysis.

Background: The COPD Assessment Test (CAT) has been recently developed to quantify COPD impact in routine practice. However, no relationship with other measures in the Global Initiative for Obstructive Lung Disease (GOLD) strategy has been evaluated. The present study aimed to evaluate the relationship of the CAT with other GOLD multidimensional axes, patient types, and the number of comorbidities.

Factors associated with inadequate diagnosis of COPD: On-Sint cohort analysis.

Background: The purpose of this study was to evaluate the frequency of inadequate diagnosis and factors predictive of this in patients with chronic obstructive pulmonary disease (COPD) participating in the On-Sint study.

Methods: The On-Sint cohort was recruited for a multicenter observational study in which 356 physicians (71.6% from primary care) included adult patients who had been diagnosed with COPD.

Patient-reported outcomes and considerations in the management of COPD: focus on aclidinium.

Chronic obstructive pulmonary disease (COPD) is a complex heterogeneous disease, in which several factors combine to give the final clinical expression. Both early and more recent studies have shown that forced expiratory volume in one second (FEV1), despite being an extremely important parameter to predict the progression of the disease, is a poor surrogate marker for symptoms perception. Accordingly, patient-reported outcomes (PROs) have gained popularity as a measure of the impact of treatment from the patients' perspective, since they represent the individuals' perception of their health status, beyond any physiological limitations.
