Metallic wire expandable stents are increasingly used to alleviate tracheal obstruction due to malignancies. Patients usually tolerate these stents well and benefit from good to excellent palliation of their symptoms. Nevertheless, some miserable complications have also come to our notice. We report here an unfortunate case in whom severe bilateral main bronchial obstruction occurred immediately after the insertion of a Wall-stent over the tracheal stenosis.

Objective: In severe equine asthma, structural remodeling of the airways ultimately leads to bronchial wall thickening and airflow obstruction. Increased bronchial vascularization has been described in horses affected by the severe form of the disease, but whether it contributes to bronchial remodeling in milder forms of asthma remains to be determined. In a blinded, retrospective case-control study, we evaluated the presence of bronchial angiogenesis in horses with mild and moderate equine asthma (MEA) and its correlation to airway smooth muscle remodeling.

Chronic obstructive pulmonary disease (COPD) is characterized by chronic inflammation, airway obstruction, and lung damage, often triggered by cigarette smoke. Dysregulated autophagy and inflammation are key contributors to its progression. Although double-stranded RNA-binding protein Staufen homolog 1 (STAU1), a multifunctional protein primarily involved in mRNA transport and localization, is identified as a potential biomarker, its role in COPD pathogenesis remains unclear.

Objectives: We hypothesized that semiquantitative visual scoring of lung MRI is suitable for GOLD-grade specific characterization of parenchymal and airway disease in COPD and that MRI scores correlate with quantitative CT (QCT) and pulmonary function test (PFT) parameters.
Methods: Five hundred ninety-eight subjects from the COSYCONET study (median age = 67 (60-72)) at risk for COPD or with GOLD1-4 underwent PFT, same-day paired inspiratory/expiratory CT, and structural and contrast-enhanced MRI. QCT assessed total lung volume (TLV), emphysema, and air trapping by parametric response mapping (PRM, PRM) and airway disease by wall percentage (WP).

Background: Severe respiratory complications following kidney transplantation have been reported, yet remain poorly understood in the pediatric population. This study aimed to document respiratory disease in this population.
Methods: At annual follow-ups, patients completed a respiratory symptoms questionnaire and underwent pulmonary function tests (PFTs).

Mucins 5AC (MUC5AC) and 5B (MUC5B) are the major mucins providing the organizing framework for the airway's mucus gel. We retrieved bronchial mucosal biopsies and bronchial wash (BW) samples through bronchoscopy from patients with chronic obstructive pulmonary disease ( = 38), healthy never-smokers ( = 40), and smokers with normal lung function ( = 40). The expression of MUC5AC and MUC5B was assessed immunohistochemically.
