Introduction: Hearing loss (HL) is considered a potentially modifiable risk factor for dementia. We aimed to examine the relationship between HL and incident dementia diagnosis in a province-wide population-based cohort study with matched controls. Methods: Administrative healthcare databases were linked to generate a cohort of patients who were aged ≥40 years at their first claimed hearing amplification devices (HAD) between April 2007 and March 2016 through the Assistive Devices Program (ADP) (257,285 with claims and 1,005,010 controls). The main outcome was incident dementia diagnosis, ascertained using validated algorithms. Dementia incidence was compared between cases and controls using Cox regression. Patient, disease, and other risk factors were examined. Results: Dementia incidence rates (per 1,000 person-years) were 19.51 (95% confidence interval [CI]: 19.26–19.77) and 14.15 (95% CI: 14.04–14.26) for the ADP claimants and matched controls, respectively. In adjusted analyses, risk of dementia was higher in ADP claimants compared with controls (hazard ratio [HR]: 1.10 [95% CI: 1.09–1.12, p < 0.001]). Subgroup analyses showed a dose-response gradient, with risk of dementia higher among patients with bilateral HADs (HR: 1.12 [95% CI: 1.10–1.14, p < 0.001]), and an exposure-response gradient, with increasing risk over time from April 2007-March 2010 (HR: 1.03 [95% CI: 1.01–1.06, p = 0.014]), April 2010-March 2013 (HR: 1.12 [95% CI: 1.09–1.15, p < 0.001]), and April 2013-March 2016 (HR: 1.19 [95% CI: 1.16–1.23, p < 0.001]). Conclusion: In this population-based study, adults with HL had an increased risk of being diagnosed with dementia. Given the implications of HL on dementia risk, understanding the effect of hearing interventions merits further investigation. [ABSTRACT FROM AUTHOR]

Background: The advancement of Otolaryngology—Head and Neck Surgery (OHNS) as a specialty relies on excellence in research. The Journal of Otolaryngology-Head and Neck Surgery is an open access, peer-reviewed journal publishing on all aspects and subspecialities of OHNS. It is the official journal of the Canadian Society of Otolaryngology—Head and Neck Surgery. This study aims to analyze bibliometric trends in authorships and institutional contributions within the Journal of Otolaryngology-Head and Neck Surgery over a 9-year period. Methods: All research articles published online in the journal were analyzed from 2013 to the end of 2021. The professional designation of all authors was recorded along with the article type, article category, institutional affiliations and international collaborations. Cochran–Armitage trend tests were used to assess the change in proportion over time between years and groups. Results: Of the 603 articles, 20 were excluded as they represented correspondence or corrections, or author identity could not be determined. 583 articles with 3409 total authors were included. Number of first authors with a Doctor of Medicine (MD) degree decreased from 90.2 to 85.3% (P = 0.165). Sub-group analysis of non-MD first authors demonstrated a significant increase in medical students as first authors from 1.6 to 11.8% (P = 0.008). Senior author degree demonstrated a significant increase in MD degree from 96.7 to 98.5% (P = 0.002). Analysis of article categories demonstrated a significant decrease in education and head and neck surgery related articles from 8.2 to 2.9% (P = 0.032) and 44.3 to 29.4% (P = 0.028) respectively. Pediatric otolaryngology articles increased significantly from 0 to 5.9% (P < 0.0001). Systematic and scoping reviews significantly increased, from 3.3 to 10.3% (P = 0.015) and original research significantly decreased from 83.6 to 82.4% (P < 0.0001). There was a significant decrease in Canadian/international collaborations from 14.3 to 4.7% (P = 0.037). There was a significant increase in international first and senior authors, from 23.0 to 36.8% (P = 0.008) and 19.7 to 38.2% (P = 0.002) respectively. Conclusion: The landscape of the journal is evolving with increased representation of non-MDs and international authors along with content that reflects higher level of scientific evidence. Future studies should characterize trends in other Otolaryngology journals to understand the research trajectory within the field. [ABSTRACT FROM AUTHOR]
