Background: Airway obstruction is a characteristic spirometric finding in asthma but the clinical significance of other abnormal spirometric patterns is less well described. We aimed to explore pre- and post-bronchodilator (BD) prevalences and clinical characteristics of preserved ratio impaired spirometry (PRISm), dysanapsis and airflow obstruction with low forced expiratory volume in 1 s (FEV) in children diagnosed with asthma.
Methods: We extracted specialist care data (clinical and spirometry) from the Swedish National Airway Register (n=3301, age 5-17 years).

Division of Pulmonary and Allergy, Department of Internal Medicine, Konkuk University Hospital, School of Medicine, Konkuk University, Seoul, Korea.
Background: Little is known about the transition to frequent exacerbators in stabilized patients with chronic obstructive pulmonary disease (COPD).
Methods: This study utilized data obtained from the Korean COPD subgroup study cohort (KOCOSS), including 511 patients with infrequent exacerbations. The outcome for these groups was progression to frequent exacerbators.

Department of Respiratory Medicine, Beijing Ditan Hospital, Capital Medical University, Beijing, People's Republic of China.
Introduction: The advent of highly active antiretroviral therapy (HAART) has changed infection by human immunodeficiency virus (HIV) from an acute disease to a manageable chronic condition; however, pulmonary complications continue to affect patient quality of life. The goal of this research was to examine the link between CD4+ levels, viral load, and respiratory function in patients infected with HIV.
Methods: Patients were grouped as HIV-infected and non-infected (1:2 ratio).
Int J Chron Obstruct Pulmon Dis
September 2025
Department of Pulmonary and Critical Care Medicine, The First People's Hospital of Yunnan Province, The Affiliated Hospital of Kunming University of Science and Technology, Kunming, Yunnan, People's Republic of China.
Purpose: Small airway dysfunction (SAD) is a key early marker of chronic obstructive pulmonary disease (COPD) development. While many studies have examined the link between SAD and early COPD, the epidemiology of SAD in high-risk COPD populations remains understudied.
Patients And Methods: This cross-sectional study utilized a multi-stage randomized cluster sampling method and recruited 11,095 adult residents aged ≥20 years from different elevations in Yunnan Province, China.

Introduction: This study aimed to evaluate the association between short-term ozone exposure and anxiety and depressive symptoms in a nationally representative Chinese population and to explore the mediating role of lung function.
Methods: This study included 42,234 Chinese adults from the China Pulmonary Health Study, conducted from 2012 to 2015. Ozone and other meteorological exposures were matched to participants' residential addresses based on latitude and longitude coordinates.
