Inhibitors of cyclin-dependent kinases 4/6 (CDK4/6) block cell cycle progression and are commonly used for treatment of several forms of cancer. Due to their anti-proliferative mode of action, we hypothesized ...

Blood neutrophil counts are associated with exacerbation frequency and mortality in COPD

mer, 01/07/2020 - 02:00
Identifying patients with COPD at increased risk of poor outcomes is challenging due to disease heterogeneity. Potential biomarkers need to be readily available in real-life clinical practice. Blood eosinophil...

Transcriptomic profiling reveals disease-specific characteristics of epithelial cells in idiopathic pulmonary fibrosis

mar, 30/06/2020 - 02:00
Idiopathic pulmonary fibrosis (IPF) is an incurable disease characterized by progressive lung fibrosis ultimately resulting in respiratory failure and death. Recurrent micro-injuries to the alveolar epithelium...

Acute exacerbations of COPD versus IPF in patients with combined pulmonary fibrosis and emphysema

mar, 30/06/2020 - 02:00
Patients with combined pulmonary fibrosis and emphysema (CPFE) may develop acute exacerbations of IPF (AE-IPF) or COPD (AE-COPD). The incidence and the characteristics of exacerbations in patients with CPFE (e...

Impact of coronavirus disease 2019 on pulmonary function in early convalescence phase

lun, 29/06/2020 - 02:00
This study investigated the influence of Coronavirus Disease 2019 (COVID-19) on lung function in early convalescence phase.

Cardiac biomarkers of prognostic importance in chronic obstructive pulmonary disease

ven, 26/06/2020 - 02:00
Ischemic heart disease is common in COPD and associated with worse prognosis. This study aimed to investigate the presence and prognostic impact of biomarkers of myocardial injury and ischemia among individual...

Shp2 positively regulates cigarette smoke-induced epithelial mesenchymal transition by mediating MMP-9 production

ven, 26/06/2020 - 02:00
Cigarette smoke (CS) is a major risk factor for the development of lung cancer and chronic obstructive pulmonary disease (COPD). Epithelial-mesenchymal transition (EMT) commonly coexists in lung cancer and COP...

Host DNA released by NETosis in neutrophils exposed to seasonal H1N1 and highly pathogenic H5N1 influenza viruses

mar, 23/06/2020 - 02:00
Neutrophil is of the most abundant number in human immune system. During acute influenza virus infection, neutrophils are already active in the early phase of inflammation - a time in which clinical biopsy or ...

Adoption of a dedicated multidisciplinary team is associated with improved survival in acute pulmonary embolism

lun, 22/06/2020 - 02:00
Acute pulmonary embolism remains a significant cause of mortality and morbidity worldwide. Benefit of recently developed multidisciplinary PE response teams (PERT) with higher utilization of advanced therapies...

Improving the evaluation of COPD exacerbation treatment effects by accounting for early treatment discontinuations: a post-hoc analysis of randomized clinical trials

lun, 22/06/2020 - 02:00
Chronic obstructive pulmonary disease (COPD) clinical trials aimed at evaluating treatment effects on exacerbations often suffer from early discontinuations of randomized treatment. Treatment discontinuations ...

Predictive factors of severe coronavirus disease 2019 in previously healthy young adults: a single-center, retrospective study

lun, 22/06/2020 - 02:00
Several previously healthy young adults have developed Coronavirus Disease 2019 (COVID-19), and a few of them progressed to the severe stage. However, the factors are not yet determined.
