Gender representation in leadership & research: a 13-year review of the Annual Canadian Society of Otolaryngology Meetings

BACKGROUND

The gender disparity in surgical disciplines, specifically in speakers across North American medical and surgical specialty conferences, has been highlighted in recent literature. Improving gender diversity at society meetings and panels may provide many benefits. Our aim was to determine the state of gender diversity amongst presenters and speakers at the annual Canadian Society of Otolaryngology-Head and Neck Surgery (CSO) meetings.

METHODS

Scientific programs for the CSO annual meetings from 2008 to 2020 were obtained from the national society website. Participant name, role, gender, location, and subspecialty topic were recorded for all roles other than poster presenter. Gender (male or female) was determined using an online search. The total number of opportunity spots and proportion of women was then calculated. Gender differences were analyzed using chi-square test and logistic regression with odds ratios. Four categories were analyzed: Society Leadership, Invited Speaker Opportunities, Workshop Composition (male-only panels or "manels", female-only panels, or with at least one female speaker), and Oral Paper Presenters (first authors).

RESULTS

There were 1874 leadership opportunity spots from 2008 to 2020, of which 18.6% were filled by women. Among elected leadership positions in the society, only 92 unique women filled 738 leadership opportunity spots. 13.2% of workshop chairs, 20.8% of panelists and 22.7% of paper session chairs were female. There was an overall increase in the proportion of leadership positions held by women, from 13.9% of leadership spots in 2008 to 30.1% in 2020. Of the 368 workshops, 61.1% were led by men only, 36.4% by at least 1 female surgeon, and 2.5% by women only. "Manels" have comprised at least 37.5% of workshops each year.

CONCLUSIONS

The proportion of women in speaking roles at the annual CSO meetings has generally increased over time, particularly among panelists, leading to fewer male-only speaking panels. However, there has been a slower rate of growth in the proportion of unique women in speaker roles. There remains an opportunity to increase gender/sex diversity at the major Canadian otolaryngology meeting.

Gender differences in publication rates at Canadian Society of Otolaryngology-Head and Neck Surgery annual meetings: an 11-year analysis

BACKGROUND

Evaluating gender differences in publication rates after conference presentations is an avenue to assess women's contributions to academic medicine. The objective of this study was to assess gender differences in publication rates, time to publication, and subspeciality of publication of abstracts presented at Canadian otolaryngology conferences over an 11-year period.

METHODS

Cross-sectional data was obtained from online conference schedules of annual Canadian Society of Otolaryngology-Head and Neck Surgery national meetings between 2009 and 2020. A total of 2111 abstract titles were searched in MedLine via PubMed. Gender of the first and senior author, publication status of presented work, and subspeciality of publication were extracted.

RESULTS

Of 2111 scientific abstracts presented between 2009 and 2020, female first and senior authors accounted for 29.0% and 12.8% of published abstracts, respectively. There was a significant difference in the publication rate of senior authors by gender (p < 0.01). Male senior authors had a 9.70% higher rate of publication compared to female senior authors. Posters with a female first author were 33.0% (OR: 0.67; 95% CI 0.49-0.91) less likely to be published compared to posters with a male first author. Similarly, posters with a female senior author were 34.0% (OR: 0.66; 95% CI 0.45-0.96) less likely to be published. There was a significant difference in discipline of publication by gender of the senior author (p < 0.001). Male senior authors were more likely to supervise projects in otology while female senior authors were more likely to supervise projects in education and pediatrics. The time to publication and impact factor of the journal of publication did not differ by gender.

CONCLUSION

Gender disparities exist in the publication rates of first and senior authors at Canadian otolaryngology meetings. Female senior authors have significantly lower publication rates compared to their male colleagues and differences exist in publication rates after poster presentations. Investigation of gender gaps in academic medicine, research productivity, and publications is essential for development of a diverse, equitable, and inclusive workforce in otolaryngology.

Scoping Review: Research Training During Medical School

Fostering skills in research is important for medical schools. This scoping review examined undergraduate curricular structures devoted to research training and their outcomes. For the sixty papers meeting inclusion criteria, descriptive statistics and a thematic analysis were conducted. Forty (67%) articles described US programs, with 30 (50%) being mandatory. Timing of research training was variable across included studies with the majority (58%) describing embedded longitudinal curricula. Reported benefits included enhanced knowledge, improved research and writing skills, clarity around career plans, and mentoring relationships. There are many curricular structures for undergraduate research training, but no high-quality evidence to support particular designs.

The efficacy of diluted topical povidone-iodine rinses in the management of recalcitrant chronic rhinosinusitis: a prospective cohort study

PURPOSE

Recalcitrant chronic rhinosinusitis is a persistent inflammatory condition of the sinonasal mucosa despite adequate medical therapy and sinus surgery. This study aimed to demonstrate the effectiveness and safety of dilute povidone-iodine (PVP-I) sinonasal rinses as an adjunctive therapy.

METHODS

Prospective cohort study. Twenty-nine recalcitrant CRS patients with endoscopic evidence of ongoing inflammation and purulent discharge were prescribed 0.08% diluted PVP-I rinses. Changes to endoscopic modified Lund-Kennedy (MLK) scores at 7 weeks post-PVP-I rinsing served as the primary outcome measure.

RESULTS

The median MLK-discharge score significantly decreased in all patients by 1.50 points post-PVP-I rinsing (p value < 0.01). The total MLK score significantly decreased in all patients by 1.50 points (p value = 0.01). Up to a 17% reduction in serum inflammatory markers was measured post-PVP-I rinsing. Sinonasal culture revealed a shift from moderate-heavy growth to lighter bacterial growth overall. Subjective SNOT-22 scores significantly improved overall by ≥ 1 minimal clinically important difference (MCID > 12; baseline median = 33; follow-up median = 20; p value < 0.01; n = 22). TSH levels increased non-significantly within normal ranges (baseline median = 1.59 mU/L; follow-up median = 1.92 mU/L; p = 0.10; n = 15). Mucociliary clearance time increased non-significantly within normal ranges (baseline median = 9 min; follow-up median = 10 min; p value = 0.53; n = 17). Olfactory Sniffin'16 scores non-significantly decreased within age-related normal ranges (baseline median = 14; follow-up median = 13; p value = 0.72; n = 18).

CONCLUSION

A dilute 0.08% PVP-I sinonasal rinse as an ancillary therapy in recalcitrant CRS significantly reduces signs of infection alongside notable symptom improvement, without affecting thyroid function, mucociliary clearance or olfaction.

A Clinical Classification Scheme for Tracheobronchomegaly (Mounier-Kuhn Syndrome)

INTRODUCTION

Tracheobronchomegaly (Mounier-Kuhn Syndrome) is a rare disease characterized by tracheal enlargement and associated loss of elastic fibers in the trachea and main bronchi.

MATERIALS

MEDLINE, Index Medicus, and other databases were searched with pre-defined criteria to identify cases of tracheobronchomegaly (TBM). Two new cases of TBM were also identified from the Provincial Medical Genetics Program of British Columbia.

RESULTS

We identified 166 publications describing 365 occurrences of TBM. We observed that affected individuals could be grouped into subgroups according to clinical features. Type 1A (105 individuals) consists of infants who developed TBM after having undergone fetoscopic tracheal occlusion, and Type 1B patients (24 individuals) are infants and children who developed TBM after prolonged intubation. Type 2 individuals developed TBM following recurrent pulmonary infections (2A) (14 individuals) or pulmonary fibrosis (2B) (10 individuals). Type 3 represents TBM with evidence of extra-pulmonary elastolysis (18 individuals), and Type 4 denotes the development of TBM with no clear predisposing factors (196 individuals). Both of our patients had TBM and evidence of extra-pulmonary elastolysis. As well, one patient had a mildly dilated aortic root, which is a previously unreported co-occurrence.

CONCLUSION

We introduce a novel classification scheme, which may sort patients into etiologically distinct groups, furthering our understanding of its pathogenesis and potentially, prevention or therapy. We also hypothesize that TBM and generalized elastolysis may have etiological commonalities, suggesting a need for further study.

Endothelin-1 promotes osteoprogenitor proliferation and differentiation in fetal rat calvarial cell cultures

Endothelin-1 (ET-1), a peptide produced by vascular endothelial cells, has been suggested to be one of the signaling factors between vascular and osteoblastic cells during bone growth and remodeling. The osteoinductive effects of ET-1 were tested on fetal rat calvaria which have the ability to form bone nodules in culture. ET-1 (10(-10) to 10(-6) M) dose-dependently increased cell proliferation. The effect of ET-1 (10(-8) M) on proliferation was greater than that of dexamethasone (Dex; 10(-8) M). ET-1 also increased the number of bone nodules by 146% over untreated cells, which coincided with a 3.1-fold increase in alkaline phosphatase activity. Limiting dilution assays showed that ET-1 treatment increased the number of osteoprogenitors (CFU-AP and CFU-OB) beyond what would be expected by a proliferative effect alone, indicating that ET-1 also stimulated osteoblast differentiation. Osteocalcin mRNA expression was upregulated as shown by Northern blot analysis. Using cDNA microarray analysis, ET-1 treatment resulted in an expression profile that included an upregulation of 163 genes and expressed sequence tags. Simultaneous addition of ET-1 and Dex to the medium further increased the number of bone nodules and alkaline phosphatase activity over either treatment alone. Our results show that ET-1 promotes both osteoblastic proliferation and differentiation and that the effects of ET-1 and Dex on differentiation are cooperative.
