Researchers found that a comprehensive care management program for chronic obstructive pulmonary disease (COPD) may not be safe or suitable for patients, as it led to excess mortality. In contrast, laxative-free colonography proved accurate in detecting most significant lesions and eliminated a major barrier to colon cancer screening. ...

Opioids effective in relieving severe shortness of breath in COPD patients

A Canadian study found opioids significantly improved the quality of life and relief from shortness of breath for advanced COPD patients. However, physicians were hesitant due to lack of guidance, fear of respiratory suppression, and concerns about censure. Innovative educational initiatives may help bridge this gap in care.

Inflammatory biomarkers improve the clinical prediction of mortality in COPD

A recent study found that adding inflammatory biomarkers improves the clinical prediction of mortality in patients with chronic obstructive pulmonary disease (COPD). The addition of a panel of selected biomarkers significantly improved the ability of clinical variables to predict mortality, with a C-statistic of 0.726.

Assessment of COPD exacerbation severity with the COPD Assessment Test

A new study found that the CAT questionnaire is a reliable tool for assessing COPD exacerbation severity, reflecting both exacerbation length and reduction in lung function. The CAT scores were also weakly related to systemic inflammatory markers and elevated in stable patients with a history of frequent exacerbations.

Dust storms affect subsequent emergency hospital admissions

A new study found that dust storms significantly increase the risk of hospital illnesses for respiratory illness, especially in patients with COPD. The study showed a 5% increase in risk 2 days after a dust storm episode, highlighting the need for timely warnings to avoid air pollution exposure.

Low vitamin D levels do not predict the risk of acute exacerbations of COPD

A large prospective cohort study found no relationship between baseline vitamin D levels and the frequency or timing of acute exacerbations of chronic obstructive pulmonary disease (COPD) in patients with severe COPD. Vitamin D supplementation is unlikely to have an effect on AECOPD risk in these patients.

NIPPV linked to increased hospital mortality rates in small group of patients

A small group of COPD patients who started with noninvasive positive-pressure ventilation (NIPPV) had significantly higher mortality rates when transitioned to invasive mechanical ventilation (IMV). NIPPV use increased nationwide, but this trend was associated with a higher risk of death in patients requiring subsequent IMV treatment.

4 physician organizations issue new clinical recommendations for diagnosing and treating COPD

The American College of Physicians, along with three other medical organizations, has released a joint clinical practice guideline for diagnosing and treating stable chronic obstructive pulmonary disease (COPD). The guidelines recommend obtaining spirometry to diagnose airflow obstruction in patients with respiratory symptoms, but not ...

Researchers identify mechanism underlying COPD disease persistence after smoking cessation

Cigarette smoke exposure fundamentally alters airway tissue in people with chronic obstructive pulmonary disease (COPD), leading to self-perpetuating fibrotic changes. The study reveals that cigarette smoke induces the production of pro-fibrotic cytokines and activates the NF-κB pathway, contributing to COPD persistence.
