Environmental Exposures, Chronic Sinusitis, and Olfaction in People With Cystic Fibrosis

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Environmental air pollutants may contribute to chronic rhinosinusitis (CRS), but their relationship with upper airway disease in people with cystic fibrosis (CF) remains poorly understood. This study evaluated associations between long‐term ambient air pollutant exposure and CRS severity and olfactory dysfunction in adults with CF ...

Olfactory Function in Cystic Fibrosis: Outcome Measures, Olfactory Dysfunction Prevalence and the Impact of Management—A Systematic Review and Meta‐Analysis

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Olfactory dysfunction (OD) is an increasingly recognized but under‐investigated comorbidity of cystic fibrosis (CF). Its prevalence, assessment methods, and response to CF‐directed treatment, including highly effective modulator therapy (HEMT) remains incompletely characterized.

The Mixed Neutrophilic–Eosinophilic Endotype of CRSwNP Blunts Postsurgical Improvement as Determined by the Completeness of Surgery Index

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background The Completeness of Surgery Index (CoSI) is a novel metric for assessing surgical quality in chronic rhinosinusitis with nasal polyps (CRSwNP). Structured histopathology (SHP) is helpful for characterizing drivers of inflammation. Integrating these two tools to identify patients at higher risk for surgically recalcitrant disease has
