Article Abstract
Neural changes underly hyperresponsiveness in asthma and other airway diseases. Afferent sensory nerves, nerves within the brainstem, and efferent parasympathetic nerves all contribute to airway hyperresponsiveness. Inflammation plays a critical role in these nerve changes. Chronic inflammation and pre-natal exposures lead to increased airway innervation and structural changes. Acute inflammation leads to shifts in neurotransmitter expression of afferent nerves and dysfunction of M muscarinic receptors on efferent nerve endings. Eosinophils and macrophages drive these changes through release of inflammatory mediators. Novel tools, including optogenetics, two photon microscopy, and optical clearing and whole mount microscopy, allow for improved studies of the structure and function of airway nerves and airway hyperresponsiveness.

Background: Induced sputum cell count is crucial for assessing airway inflammatory phenotypes. This study investigated how aspirin-induced bronchospasm affects sputum cell counts in patients with nonsteroidal anti-inflammatory drug-exacerbated respiratory disease (N-ERD), comparing systemic versus local aspirin administration.
Methods: Seventy-eight patients with N-ERD and 39 with aspirin-tolerant asthma (ATA) participated.

Background: Allergic rhinitis (AR) is an increasingly prominent global public health issue, where air pollution significantly contributes to its rising incidence. Although numerous studies have explored the link between air pollution and AR pathogenesis, comprehensive summaries are still limited.
Objective: This study performs a bibliometric analysis to identify research hotspots and emerging trends, offering insights into AR prevention and management.

Plastics, particularly polystyrene (PS), are extensively used worldwide, especially in disposable packaging, which contributes to environmental pollution by generating microplastic particles. Herein, we investigated the pulmonary toxic effects of PS microplastics, focusing on airway inflammation and immune response. PS microplastic (50 nm to 1 μm) exposure was more likely to cause a severe pulmonary inflammatory response, particularly with smaller particle sizes.

Background: This study aimed to evaluate the impact of asthma severity on biventricular cardiac functions using tissue Doppler imaging (TDI), two-dimensional speckle tracking echocardiography (2D-STE), and three-dimensional speckle tracking echocardiography (3D-STE).
Methods: Sixty-three children with asthma, aged between 5 and 16 years, were enrolled in the study along with 63 matched controls. All participants underwent cardiac assessments, including TDI, 2D-STE, 3D-STE, conventional echocardiography, and pulmonary function testing with spirometry.
