Chronic obstructive pulmonary disease refers to a group of lung diseases that block airflow and make breathing difficult, which is most commonly caused by tobacco smoke, with a number of other factors like dust, air pollution and genetic disorders. The inflammatory responses are triggered in the lung of COPD patients along with narrowing of the airways which makes breathing difficult. Emphysema, chronic bronchitis and chronic obstructive airways disease are the common conditions that make up COPD. The symptoms are frequent chest infections including cough, shortness of breath, exerbation and others. COPD is a preventable and treatable disease characterized by airflow limitation that is not fully reversible. Smoking cessation and medication help managing chronic obstructive pulmonary disease.
Review articles are the summary of current state of understanding on a particular research topic.
Review article comes in the form of systematic reviews and literature reviews and are a form of secondary literature. Systematic reviews determine an objective list of criteria, and find all previously published original research papers that meet the criteria. They then compare the results presented in these papers. Literature reviews, by contrast, provide a summary of what the authors believe are the best and most relevant prior publications.
The concept of review article is separate from the concept of peer-reviewed literature. It is possible for a review to be peer-reviewed, and it is possible for a review to be non-peer-reviewed.
