Background: Chronic obstructive pulmonary disease (COPD) remains a major public health problem. It is the fourth leading cause of chronic morbidity and mortality in the United States, and is projected to rank fifth in 2020 in burden of disease caused worldwide. Objective: To research the epidemiology of COPD in the population of Bac Giang city and finding out the risk factors of COPD. Subjects and method: Cross-sectional survey of general population sample of 2,104 men and women with the age \ufffd?0 years in 30 wards of 11 communes of Bac Giang city. Data on respiratory symptoms, diseases, and risk factors were collected. Lung function tests were performed with Spiroanalyzer snoo, Japan. Results and conclusions: The incidence of COPD was 2.3%; in men 3.0% and in women 1.7%. The incidence of simple chronic bronchitis was 6.4%. People who smoked had higher rate of COPD than the others (OR = 2.8). The incidence of smoking in COPD was 55.9%. The three most important risk factors of COPD was the age \ufffd?0; smoking >15 pack/year and medical history of asthma.

Background: Bronchoscopy is an essential technique for diagnosis of some lung diseases by taking samples for histological and cytological tests. Objective: To assess the role of transbronchial lung biopsy procedure in diagnosis some parenchymal pulmonary diseases. Subjects and method: A retrospective study conducted in 50 patients with diffuse and localized lung diseases, who were admitted to the Department of Respiratory in Bach Mai Hospital, from January 2003 to December 2005. Results: Transbronchial lung biopsy confirmed the diagnosis in 30 of 50 (60%) cases; with localized malignant lesions (12%), diffuse lung disease (16%), tuberculosis (28%), and cystic fibrosis (4%). Following transbronchial lung biopsy, two patients had pneumothorax (1 patient had chest tube drainage) and five patients had hemoptysis but no of them required further treatment. Conclusions: Transbronchial lung biopsy offer good diagnostic accuracy and low complication rate.

Background:
To assess the alterations in exacerbation rates, other clinical outcomes, and to identify persistent challenges in the management of chronic obstructive pulmonary disease (COPD) in Vietnamese COPD management units (CMUs).
Methods:
A multi-center, prospective cohort study was conducted on COPD within the CMUs of three study sites. The primary endpoint was exacerbation frequency. Data on demographic and clinical characteristics were collected at the initiation of the study. Participants were followed for 12 to 15 months after enrollment.
Results:
Throughout the follow-up period, a decrease was noted in the prevalence of patients requiring hospitalization (from 42.3% to 34.4%) and intensive care unit/emergency department admissions (from 5.7% to 0.6%). The annual rates of exacerbation and hospitalization were 0.75±0.89 and 0.56±0.70, respectively. Factors such as symptom severity, degree of airflow obstruction, and body mass index were associated with increased exacerbation frequency and elevated annual exacerbation rates. Our findings underscore the complexities and obstacles encountered in managing COPD during the coronavirus disease 2019 (COVID-19) pandemic, including the rise in smoking prevalence, inadequate testing rates, and non-compliance with established treatment guidelines.
Conclusion
Our study elucidates the challenges and difficulties in managing COPD amidst the COVID-19 pandemic, highlighting issues such as increased smoking rates, insufficient testing, and deviations from established therapeutic guidelines. These insights lay the groundwork for future intervention strategies and policy enhancements.
