Abstract
Rationale: Bronchiectasis is an airway inflammatory disease that is frequently associated with chronic rhinosinusitis (CRS). An eosinophilic endotype of bronchiectasis has recently been described, but detailed testing to differentiate eosinophilic bronchiectasis from asthma has not been performed. Objectives: This prospective observational study aimed to test the hypotheses that bronchiectasis with CRS is enriched for the eosinophilic phenotype in comparison with bronchiectasis alone and that the eosinophilic bronchiectasis phenotype exists as a separate entity from bronchiectasis associated with asthma. Methods: People with idiopathic or postinfectious bronchiectasis were assessed for concomitant CRS. We excluded people with asthma or primary ciliary dyskinesia and smokers. We assessed sputum and blood cell counts, nasal NO and fractional excreted NO, methacholine reactivity, skin allergy testing and total and specific immunoglobulin (Ig) E, cytokines in the sputum and serum, and the microbiome in the sputum and nasopharynx. Results: A total of 22 people with CRS (BE + CRS) and 17 without CRS (BE - CRS) were included. Sex, age, Reiff score, and bronchiectasis severity were similar. Median sputum eosinophil percentages were 0% (IQR, 0-1.5%) in BE - CRS and 3% (1-12%) in BE + CRS (P = 0.012). Blood eosinophil counts were predictive of sputum eosinophilia (counts ⩾3%; area under the receiver operating characteristic curve, 0.68; 95% confidence interval, 0.50-0.85). Inclusion of CRS improved the prediction of sputum eosinophilia by blood eosinophil counts (area under the receiver operating characteristic curve, 0.79; 95% confidence interval, 0.65-0.94). Methacholine tests were negative in 85.7% of patients in the BE - CRS group and 85.2% of patients in the BE + CRS group (P > 0.99). Specific IgE and skin testing were similar between the groups, but total IgE levels were increased in people with increased sputum eosinophils. Microbiome analysis demonstrated distinct microbiota in nasopharyngeal and airway samples in the BE + CRS and BE - CRS groups, without significant differences between groups. However, interactome analysis revealed altered interactomes in individuals with high sputum eosinophil counts and CRS. Conclusions: Bronchiectasis with CRS is associated with an eosinophilic airway inflammation that is distinct from asthma.

Abstract
OBJECTIVE Rhinitis medicamentosa poses a therapeutic challenge for both patients and physicians. Treatment strategies vary, starting with avoidance of decongestants, followed by medications or surgical intervention. This study aimed to compare two treatment strategies for this condition. METHODS A review was conducted of patients diagnosed with rhinitis medicamentosa from 2013 to 2021, who were managed conservatively with medications or surgically by inferior turbinate reduction. RESULTS Forty-seven patients were included: 21 patients were treated conservatively and 26 underwent turbinate reduction. Following surgical therapy, the frequency of using decongestants was significantly reduced (p < 0.001), with a significant improvement in Sino-Nasal Outcome Test-22 scores (p < 0.001). The conservative treatment group was significantly older with more co-morbidities. Following medical therapy, the conservative treatment group had a significant decrease in the frequency of decongestant use, but there was no significant improvement in their Sino-Nasal Outcome Test-22 scores. CONCLUSION Compared to conservative treatment, inferior turbinate reduction for rhinitis medicamentosa resulted in reduced decongestant use and improved quality of life.

Abstract
The association of bronchiectasis with chronic rhinosinusitis (CRS) has been reported. However, apart from primary ciliary dyskinesia (PCD) and cystic fibrosis (CF), predisposing conditions have not been established. We aimed to define clinical and laboratory features that differentiate patients with bronchiectasis with upper airway symptoms (UASs) and without PCD from patients without UASs. We reviewed charts of adults with bronchiectasis, excluding CF and PCD. UASs were defined as nasal discharge most days of the year, sinusitis or nasal polyps. Laboratory data included IgG, total IgE, blood eosinophils, sputum bacteriology and lung function. A radiologist blinded to UAS presence scored bronchiectasis (Reiff score) and sino-nasal pathology (Lund–Mackay score). Of 197 patients, for the 70 (35%) with UASs, symptoms started earlier (34±25 versus 46±24 years; p=0.001), disease duration was longer (median 24 versus 12 years; p=0.027), exacerbations were more frequent (median 3 versus 2 per year; p=0.14), and peripheral blood eosinophil (median 230 versus 200 μL−1; p=0.015) and total IgE (median 100 versus 42 IU·mL−1; p=0.085) levels were higher. The sinus computed tomography score was independently associated with exacerbations, with 1 point on the Lund–Mackay score associated with a 1.03-fold increase in the number of exacerbations per year (95% CI 1.0–1.05; p=0.004). These findings may implicate a higher disease burden in patients with UASs. We hypothesise that UASs precede and may in some cases lead to the development of bronchiectasis. Involvement of the upper airway in patients with bronchiectasis is associated with an early age of onset and allergic featureshttp://ow.ly/1BuK30gWDrN

Abstract
Activity of heparanase is implicated strongly in dissemination of metastatic tumor cells and cells of the immune system. In addition, heparanase enhances the phosphorylation of selected signaling molecules, including SRC and EGFR, in a manner that requires secretion but not enzymatic activity of heparanase and is mediated by its C-terminal domain. Clinically, heparanase staining is associated with larger tumors and increased EGFR phosphorylation in head and neck carcinoma. We hypothesized that signal transducer and activator of transcription (STAT) proteins mediate the protumorigenic function of heparanase downstream of the EGFR. We provide evidence that heparanase enhances the phosphorylation of STAT3 and STAT5b but not STAT5a. Moreover, enhanced proliferation of heparanase transfected cells was attenuated by STAT3 and STAT5b siRNA, but not STAT5a or STAT1 siRNA. Clinically, STAT3 phosphorylation was associated with head and neck cancer progression, EGFR phosphorylation, and heparanase expression and cellular localization. Notably, cytoplasmic rather than nuclear phospho-STAT3 correlated with increased tumor size (T-stage; p = 0.007), number of metastatic neck lymph nodes (p = 0.05), and reduced survival of patients (p = 0.04).
