Quebec French Translation, Cultural Adaptation, and Validation of the Singing Voice Handicap Index-10 Questionnaire for Singers with Dysphonia.

Objectives/hypothesis: Dysphonia is a common voice disorder that can significantly impact a person's life; it requires a collaborative evaluation by both speech-language pathologists and otolaryngologists that takes the patient's perspective into account. The aim of this study was to translate and culturally adapt the Singing Voice Handicap Index questionnaire (SVHI-10), a reliable patient-reported outcome evaluation tool for dysphonia, for the Quebec French population. The result is the Singing Voice Handicap Index-10-QC (SVHI-10-QC).

Response to intranasal probiotic supplementation in refractory CRS is associated with modulation of non-type 2 inflammation and epithelial regeneration.

Justification: We have previously documented that in individuals with chronic rhinosinusitis (CRS) refractory to surgery, intranasal application of live , a probiotic bacterium, improves sinus-specific symptoms, SNOT-22, and mucosal aspect on endoscopy, accompanied by a reduction in sinus pathogens and an increase in protective bacteria. The present work explores the molecular mechanisms underpinning these observations using transcriptomics of the sinus mucosa.

Method: Epithelial brushings collected prospectively as a sub-study of the clinical trial were used to probe epithelial responses to microbiome supplementation using a hypothesis-free bioinformatic analysis of gene expression analysis.
