Interaction study of the effects of environmental exposure and gene polymorphisms of inflammatory and immune-active factors on chronic obstructive pulmonary disease.

Background: Chronic obstructive pulmonary disease (COPD) is a heterogeneous disease, influenced by both environmental and genetic factors. Single nucleotide polymorphism (SNP) in the human genome may influence the risk of developing COPD and the response to treatment. We assessed the effects of gene polymorphism of inflammatory and immune-active factors and gene-environment interaction on risk of COPD in middle-aged and older Chinese individuals.

Background: Chronic obstructive pulmonary disease (COPD) is a chronic and progressive lung disease. Disulfidptosis-related genes (DRGs) may be involved in the pathogenesis of COPD. From the perspective of predictive, preventive, and personalized medicine (PPPM), clarifying the role of disulfidptosis in the development of COPD could provide a opportunity for primary prediction, targeted prevention, and personalized treatment of the disease.

Background: Pathobiology of asthma and chronic obstructive pulmonary disease (COPD) is associated with changes among respiratory epithelium structure and function. Increased levels of PM from urban particulate matter (UPM) are correlated with enlarged rate of asthma and COPD morbidity as well as acute disease exacerbation. It has been suggested that pre-existing pulmonary obstructive diseases predispose epithelium for different biological response than in healthy airways.

Department of Diagnostic and Interventional Radiology, University Hospital of Heidelberg, Heidelberg, Germany.
Objectives: We hypothesized that semiquantitative visual scoring of lung MRI is suitable for GOLD-grade specific characterization of parenchymal and airway disease in COPD and that MRI scores correlate with quantitative CT (QCT) and pulmonary function test (PFT) parameters.
Methods: Five hundred ninety-eight subjects from the COSYCONET study (median age = 67 (60-72)) at risk for COPD or with GOLD1-4 underwent PFT, same-day paired inspiratory/expiratory CT, and structural and contrast-enhanced MRI. QCT assessed total lung volume (TLV), emphysema, and air trapping by parametric response mapping (PRM, PRM) and airway disease by wall percentage (WP).
GLITTRE-ADL TESTS IN THREE LAPS AS AN ALTERNATIVE TO THE FIVE LAPS TEST.

Allied Health Professorial Unit, Sydney Local Health District, Sydney, New South Wales, Australia; Faculty of Health Sciences, University of Sydney, Sydney, New South Wales, Australia.
Background: The Glittre-ADL test is a comprehensive test to evaluate functional capacity in patients with chronic obstructive pulmonary disease (COPD).
Aim: The primary aim was to validate the Glittre-ADL test with and without the backpack performed in three laps as an alternative of five laps in people with COPD.
Methods: Forty-eight participants with mild to severe COPD (mean±SD age: 71±7 years; FEV: 46 ± 17 %predicted) were recruited and performed two six-minute walk tests (visit 1); two Glittre-ADL tests with backpack (visit 2), and the Glittre-ADL test with and without the backpack, in random order (visit 3).
