COPD Exacerbations, Air Pollutant Fluctuations, and Individual-Level Factors in the Pandemic Era

International Journal of COPD, Journal Year: 2025, Volume and Issue: Volume 20, P. 735 - 751

Pandemic-era associations between air pollutant exposures and exacerbations of chronic obstructive pulmonary disease (COPD) are under-explored. Given the considerable observed pandemic-era fluctuations, these were investigated along with possible individual-level risk factors. Participants spirometry-confirmed COPD from Canadian Cohort Obstructive Lung Disease (CanCOLD) included, data collected before ("pre-pandemic") during ("pandemic") COVID-19 pandemic. Nitrogen dioxide (NO2), fine particulate matter (PM2.5), ground-level ozone (O3), total oxidant (Ox) weather obtained national databases. Associations each "symptom-based" (increased dyspnea or sputum volume/purulence ≥48hrs) "event-based" ("symptom-based" plus requiring antibiotics, corticosteroids, unscheduled healthcare use) estimated in separate models. Generalized estimating equations (GEE) models reported as rate ratios (RRs) per interquartile range (IQR) increment concentration 95% confidence intervals (95% CIs). NO2, PM2.5, Ox (NO2+O3) concentrations (but not O3) fell significantly In 673 participants both symptom-based event-based exacerbation rates likewise higher pre-pandemic period. During period, was positively associated (RR: 1.21 [1.08,1.36]). pandemic (1.46 [1.13,1.89]) (1.43 [1.00,2.05]) exacerbations.

Chronic dyspnea, a distressing symptom in patients with complex chronic conditions, is linked to higher risks of mortality. This study aimed identify nursing interventions that could improve self-management for patients, thereby enhancing control over dyspnea. The findings intend guide care strategies promote among this population.

Designing a Socially Assistive Robot to Assist Older Patients with Chronic Obstructive Pulmonary Disease in Managing Indoor Air Quality

Applied Sciences, Journal Year: 2024, Volume and Issue: 14(13), P. 5647 - 5647

Published: June 28, 2024

Chronic obstructive pulmonary disease (COPD) stems from airflow blockage and lung damage, indoor air pollution exacerbates COPD, underscoring the necessity for proactive management. Older COPD patients, prone to respiratory heat-related issues, require crucial assistance, yet their reduced awareness necessitates ongoing education identify enhance quality. To tackle this challenge, we developed a socially assistive robot (SAR) integrating IoT quality sensors guide patients in improving (IAQ). This study evaluated IAQ enhancement among older using technology, uncovering significant reduction ‘poor alerts’ with clear linear trend. Although ‘good remained consistent, machine learning models predicted improved post-alerts. Consistent alerts serve as motivating factor maintain standards. However, barriers SAR utilization, such psychological operational hurdles, need be addressed future research endeavors.
