Similarities and differences between emphysema and chronic bronchitis, two conditions that fall under COPD

(Natural News) Chronic obstructive pulmonary disease (COPD) refers to a group of life-threatening diseases that severely affect the lungs, causing breathlessness, inflammation, airway obstruction and significant bronchial damage over time. Many of the chronic respiratory diseases classified under COPD are primarily caused by exposure to tobacco smoke, but they can also be exacerbated by factors such as air quality, existing cardiovascular...

CONCLUSION: Probable ACO is associated with WTC exposures. Further study of ACO is needed to understand the development of this and other environmentally or occupationally-related airway diseases, and how to prevent these in disasters like 9/11. PMID: 32930623 [PubMed - as supplied by publisher]

Authors: Lo Bello F, Hansbro PM, Donovan C, Coppolino I, Mumby S, Adcock IM, Caramori G Abstract INTRODUCTION: Chronic obstructive pulmonary disease (COPD) is a lung disease characterised by chronic bronchitis, emphysema, and remodelling. Its prevalence is increasing worldwide, however there are few effective therapies, and none of the treatments currently available prevent the progression of the disease or target all of the hallmark features. The development and progression of COPD is heterogeneous, which has hampered the development of new therapies. AREAS COVERED: In this review, we cover the emergence of th...

This study aimed to investigate the underdiagnosis of COPD and its determinants based on the Tunisian Burden of Obstructive Lung Disease study. We collected information on respiratory history symptoms and risk factors for COPD. Post-bronchodilator (Post-BD) FEV1/FVC

Lung cancer is a common malignancy worldwide, and risk factors include bronchitis, asthma, tuberculosis, smoking, and air pollution. These are also risk factors for spontaneous pneumothorax, a benign disease. We hypothesized that patients who experience a spontaneous pneumothorax have a greater risk to develop lung cancer, and designed a study to determine if this is so. We used the population-based Taiwan Health Insurance Research Database to perform a retrospective cohort study. The database includes more than 99% of the population of Taiwan. We established a 27,405-person pneumothorax cohort and a 109,620 person compar...

Authors: Lv X, Li K, Hu Z Abstract Chronic Obstructive Pulmonary Disease (COPD) is a classical chronic respiratory disease with the pathological changes involving the bronchi and alveoli. Many of the risk factors of COPD can induce autophagy in different kinds of cells in lung tissue including alveolar epithelial cells, broncho epithelial cells, and fibroblasts. Over-activation of autophagy may cause emphysema by inducing autophagic cell death. However, the bronchitis and fibrosis may be mainly caused by autophagic flux blocking. Thus, understanding the role of autophagy in the pathogenesis of COPD is importan...

ConclusionsThe study results suggest that the end ‐expiratory pressure fluctuation affects the body tidal volume. Compared with the bilevel positive airway pressure (PAP), the trilevel PAP provides additional respiratory support to the body during a respiratory difference in initial respiration and descent.

Conclusions and Implications of Key Findings: Adults with obstructive lung diseases preferred small inhaler devices that were portable, durable, perceived as easy to use, and fast in medication administration. Healthcare providers should give due consideration to the patient's device feature preferences when developing a treatment plan that prescribes an inhalation device.

Chronic obstructive pulmonary disease (COPD) is the integrated form of chronic obstructive bronchitis and pulmonary emphysema, characterized by persistent small airway inflammation and progressive irreversible airflow limitation. COPD is characterized by acute pulmonary exacerbations and associated accelerated lung function decline, hospitalization, readmission and an increased risk of mortality, leading to huge social-economic burdens. Recent evidence suggests ~50% of COPD acute exacerbations are connected with a range of respiratory viral infections. Nevertheless, respiratory viral infections have been linked to the seve...

This study assessed the relationship between self-reported physician-diagnosed epilepsy and COPD in a large representative sample of the U.S. adult population and explored possible mechanisms. METHODS: Cross-sectional National Health Interview Surveys for 2013, 2015, and 2017 were aggregated to compare the prevalence of COPD between U.S. respondents aged ≥18 years with a history of physician-diagnosed epilepsy (n = 1783) and without epilepsy (n = 93,126). We calculated prevalence of COPD by age-standardized adjustment and prevalence ratios of COPD overall adjusted for sociodemographic and risk factors, by...
