Summary
Bronchiectasis research has significantly increased over 20 years, with the US leading publications. Future studies may focus on causes of decreased respiratory function in bronchiectasis.
Area of Science:
- Pulmonology and Respiratory Medicine
- Bibliometrics and Scientometrics
Background:
- Bronchiectasis, a condition of chronic cough and bronchial dilation, has transitioned from rare to common.
- Extensive research exists, necessitating analysis of its dynamics and trends.
Purpose of the Study:
- To conduct a bibliometric and visualization analysis of global research on bronchiectasis.
- To identify research hotspots, collaboration patterns, and developmental trajectories.
Main Methods:
- Bibliometric analysis of 6,331 articles published between 2005-2024 from Web of Science Core Collection.
- Visualization using R-Bibliometric and VOSviewer for keyword co-occurrence, co-citation, and country/institution collaboration.
Main Results:
- A consistent increase in bronchiectasis research output over the past two decades.
- The United States led in publications and citations, with key terms including 'cystic fibrosis', 'COPD', 'CT', 'asthma', 'children', 'primary ciliary dyskinesia', 'exacerbation', 'Pseudomonas aeruginosa', and 'interstitial lung disease'.
- Co-citation analysis highlighted research on the Bronchiectasis Severity Index and clinical guidelines.
Conclusions:
- Bronchiectasis research is rapidly expanding.
- Future research may concentrate on the underlying causes of reduced respiratory function.
- This study provides a comprehensive overview of bronchiectasis research trends for future studies.

COPD is defined as a heterogeneous lung condition marked by persistent respiratory symptoms such as dyspnea, cough, and sputum production, caused by abnormalities in the airways that cause airflow obstruction.
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...

Endoscopy is a non-surgical medical technique used to examine a person's internal organs and vessels. This lesson will focus on two types of endoscopic studies: bronchoscopy and thoracoscopy.
Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...

Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...

Respiratory disorders encompass a range of conditions with varying levels of severity. Asthma, marked by chronic airway inflammation and hypersensitivity, is one such condition. It can lead to airway obstruction due to factors like bronchial spasms, mucosal edema, increased mucus secretion, or epithelial damage. Asthma triggers are diverse, ranging from allergens to emotional upset, and treatment focuses on both immediate relief through bronchodilators and long-term inflammation suppression.

The human bronchi and bronchial tree play a crucial role in the respiratory system, facilitating the exchange of oxygen and carbon dioxide. Let's delve into the intricate structure and functions of these respiratory components.
The trachea, commonly known as the windpipe, is a tube that connects the larynx (voice box) to the bronchi. At a point called the carina, it bifurcates into two primary bronchi. The right primary bronchus is wider, shorter, and more vertical than the left primary...
