AI Article Synopsis
- Peripheral airway disease plays a key role in asthma, affecting symptoms, airway responsiveness, and the risk of exacerbations and inflammation.
- Advanced technology now enables routine measurement of peripheral airway function, providing a fuller understanding of asthma severity beyond just symptoms.
- Tools like oscillometry and nitrogen washout are valuable for monitoring treatment responses and assessing future risk, with a push for more physiological research to improve asthma care.
Article Abstract
Disease of the peripheral (or small) airways is fundamental in asthma, being closely related to symptoms (or lack of control of them), airway hyperresponsiveness, spirometric abnormalities, risk of loss of control, or exacerbations and inflammation. Current technology now allows routine measurement of peripheral airway function. Having a working concept of peripheral airways disease in asthma is arguably very useful to clinicians and beneficial to patients because it allows a more comprehensive assessment of asthma severity (rather than just symptoms alone, which is the norm), tracking of progress or deterioration, and assessing response to treatment. Oscillometry is a sensitive way to monitor the peripheral airways, whereas multiple breath nitrogen washout parameters are excellent measures of future risk. In the longer term, physiologic measurements will be crucial in research to define causes and find new disease-modifying treatments.

The Characteristics of the Concavity of Descending Limb of Maximal Expiratory Flow-Volume Curves Generated by Spirometry.
Lung
January 2025
National Clinical Research Center for Respiratory Disease, State Key Laboratory of Respiratory Disease, Guangzhou Institute of Respiratory Health, the First Affiliated Hospital of Guangzhou Medical University, Guangzhou, Guangdong, China.
Purpose: This study examined the concavity (angle β, central and peripheral concavity) of the descending limb of the maximal expiratory flow-volume (MEFV) curves to reflect various ventilatory defects, including obstructive, restrictive, or mixed patterns.
Methods: We conducted a cross-sectional study collecting spirometry data from a healthcare center and a tertiary hospital between 2017 and 2022, with additional raw flow-volume curve data from primary healthcare institutions in 2023. We analyzed differences in concavity between spirometric patterns.
Neuroimmune signalling pathways in chronic rhinosinusitis with nasal polyps.
Curr Opin Allergy Clin Immunol
February 2025
Specialist Allergy and Clinical Immunology, Rhinology Section, Royal National ENT and Eastman Dental Hospitals, University College London Hospitals NHS Foundation Trust, London, UK.
Purpose Of Review: To evaluate the role of neuroimmune signalling pathways in the pathogenesis of chronic rhinosinusitis with nasal polyps (CRSwNP).
Recent Findings: The sinonasal mucosa is densely infiltrated by immune cells and neuronal structures that share an intimate spatial relationship within tissue compartments. Together, such neuroimmune units play a critical role in airway defence and homeostatic function.
Polysomnographic Phenotype of Positional Obstructive Sleep Apnea.
J Rhinol
November 2024
Department of Otorhinolaryngology-Head and Neck Surgery, Kangbuk Samsung Hospital, Sungkyunkwan University School of Medicine, Seoul, Republic of Korea.
Background And Objectives: Obstructive sleep apnea (OSA) is a prevalent sleep disorder characterized by recurrent upper airway obstruction, leading to disrupted sleep and various health complications. Positional OSA (POSA) refers to patients whose OSA severity is significantly influenced by body position, especially when lying supine. This study aimed to evaluate the polysomnographic characteristics of POSA and non-positional OSA (non-POSA) and to assess their clinical implications.

Background: There are important inter-relationships between miRNAs and metabolites: alterations in miRNA expression can be induced by various metabolic stimuli, and miRNAs play a regulatory role in numerous cellular processes, impacting metabolism. While both specific miRNAs and metabolites have been identified for their role in childhood asthma, there has been no global assessment of the combined effect of miRNAs and the metabolome in childhood asthma.
Methods: We performed miRNAome-metabolome-wide association studies ('miR-metabo-WAS') in two childhood cohorts of asthma to evaluate the contemporaneous and persistent miRNA-metabolite associations: 1) Genetic Epidemiology of Asthma in Costa Rica Study (GACRS) (N = 1121); 2) the Childhood Asthma Management Program (CAMP) (N = 312 and N = 454).
Experimental Full-volume Airway Approximation for Assessing Breath-dependent Regional Aerosol Deposition.
Device
December 2024
Department of Chemical and Biomolecular Engineering, University of Delaware, Newark, DE 19716.
Modeling aerosol dynamics in the airways is challenging, and most modern personalized tools consider only a single inhalation maneuver through less than 10% of the total lung volume. Here, we present an modeling pipeline to produce a device that preserves patient-specific upper airways while approximating deeper airways, capable of achieving total lung volumes over 7 liters. The modular system, called TIDAL, includes tunable inhalation and exhalation breathing capabilities with resting flow rates up to 30 liters per minute.
