RESUMO

Rescorla (2000, 2001) interpreted his compound test results to show that both common and individual error terms regulate associative change such that the element of a conditioned compound with the greater prediction error undergoes greater associative change than the one with the smaller prediction error. However, it has recently been suggested that uncertainty, not prediction error, is the primary determinant of associative change in people (Spicer et al., 2020, 2022). The current experiments use the compound test in a continuous outcome allergist task to assess the role of uncertainty in associative change, using two different manipulations of uncertainty: outcome uncertainty (where participants are uncertain of the level of the outcome on a particular trial) and causal uncertainty (where participants are uncertain of the contribution of the cue to the level of the outcome). We replicate Rescorla's compound test results in the case of both associative gains (Experiment 1) and associative losses (Experiment 3) and then provide evidence for greater change to more uncertain cues in the case of associative gains (Experiments 2 and 4), but not associative losses (Experiments 3 and 5). We discuss the findings in terms of the notion of theory protection advanced by Spicer et al., and other ways of thinking about the compound test procedure, such as that proposed by Holmes et al. (2019). (PsycInfo Database Record (c) 2024 APA, all rights reserved).

RESUMO

OBJECTIVE: Nontuberculous mycobacteria (NTM) are environmentally acquired opportunistic pathogens that can cause recalcitrant lung disease. Prior reports have demonstrated links between shower use and infections, yet the aerosolization of NTM from showerheads, as well as the humidity levels that may modulate NTM aerosolization from showerheads is less studied. The objective of the current study was to investigate the role of humidity in NTM aerosolization among showers in homes located in a geographic area with high lung disease incidence, Hawai'i, and test whether deployment of a dehumidifier in well-ventilated bathrooms reduce NTM exposure. RESULTS: Across two sampling events and five showers, existing NTM showerhead biofilms along with shower air were sampled at three points: pre-shower, post-shower, and post-dehumidification. In each of the sampling events, respiratory relevant NTM species were identified from shower biofilms, which were also detected in aerosolized shower air after showering events, but not after the shower was dehumidified and bathrooms vented. While sample size was small, these data suggest running a shower is a possible source of NTM aerosolization and using a commercial household dehumidifier in conjunction with opening bathroom doors and windows may be simple, cost-effective interventions to reduce environmental NTM exposures.

RESUMO

To date, there are no efficacious translational solutions for end-stage urinary bladder dysfunction. Current surgical strategies, including urinary diversion and bladder augmentation enterocystoplasty (BAE), utilize autologous intestinal segments (e.g. ileum) to increase bladder capacity to protect renal function. Considered the standard of care, BAE is fraught with numerous short- and long-term clinical complications. Previous clinical trials employing tissue engineering approaches for bladder tissue regeneration have also been unable to translate bench-top findings into clinical practice. Major obstacles still persist that need to be overcome in order to advance tissue-engineered products into the clinical arena. These include scaffold/bladder incongruencies, the acquisition and utility of appropriate cells for anatomic and physiologic tissue recapitulation, and the choice of an appropriate animal model for testing. In this study, we demonstrate that the elastomeric, bladder biomechanocompatible poly(1,8-octamethylene-citrate-co-octanol) (PRS; synthetic) scaffold coseeded with autologous bone marrow-derived mesenchymal stem cells and CD34+ hematopoietic stem/progenitor cells support robust long-term, functional bladder tissue regeneration within the context of a clinically relevant baboon bladder augmentation model simulating bladder trauma. Partially cystectomized baboons were independently augmented with either autologous ileum or stem-cell-seeded small-intestinal submucosa (SIS; a commercially available biological scaffold) or PRS grafts. Stem-cell synergism promoted functional trilayer bladder tissue regeneration, including whole-graft neurovascularization, in both cell-seeded grafts. However, PRS-augmented animals demonstrated fewer clinical complications and more advantageous tissue characterization metrics compared to ileum and SIS-augmented animals. Two-year study data demonstrate that PRS/stem-cell-seeded grafts drive bladder tissue regeneration and are a suitable alternative to BAE.

RESUMO

INTRODUCTION/BACKGROUND: Enhanced Recovery After Surgery (ERAS) is a fundamental shift in perioperative care that has consistently demonstrated an improved outcome for a wide variety of surgeries in adults but has only limited evidence in the pediatric population. OBJECTIVE: We aimed to assess the success with and barriers to implementation of ERAS in a prospective, multi-center study on patients undergoing complex lower urinary tract reconstruction. STUDY DESIGN: Centers were directed to implement an ERAS protocol using a multidisciplinary team and quality improvement methodologies. Providers completed pre- and post-pilot surveys. An audit committee met after enrolling the first 5 patients at each center. Pilot-phase outcomes included enrollment of ≥2 patients in the first 6 months of enrollment, completion of 90 days of follow-up, identification of barriers to implementation, and protocol adherence. RESULTS: A total of 40 patients were enrolled across 8 centers. The median age at surgery was 10.3 years (IQR 6.4-12.5). Sixty five percent had a diagnosis of myelomeningocele, and 33 % had a ventriculoperitoneal shunt. A bladder augmentation was performed in 70 %, Mitrofanoff appendicovesicostomy in 52 %, Monti ileovesicostomy in 15 %, and antegrade continence enema channel in 38 %. The most commonly perceived barriers to implementation on the pre-pilot survey were "difficulty initiating and maintaining compliance with care pathway" in 51 % followed by a "lack of time, money, or clinical resources" in 36 %. The pre-pilot study experience, implementation, and pilot-phase outcomes are provided in the Table. All primary and secondary outcomes were achieved. DISCUSSION: The findings of the present study were similar to several small comparative studies with regard to the importance of a multidisciplinary team, strong leadership, and continuous audit for successful implementation of ERAS. Similar barriers were also encountered to other studies, which primarily related to a lack of administrative support, leadership, and buy-in from other services. The limitations of the present study included a relatively small heterogeneous cohort and absence of a comparative group, which will be addressed in the larger exploratory phase of the trial. The findings may also not be generaziable due to the need for sustainable processes that were unique to each center as well as an absence of adequate volume or resources at smaller centers. CONCLUSIONS: ERAS was successfully implemented for complex lower urinary tract reconstruction across 8 centers through a multidisciplinary team, structured approach based on the local context, and focus on a continuous audit.

RESUMO

Nontuberculous mycobacteria (NTM) are environmentally acquired opportunistic pathogens that cause chronic lung disease in susceptible individuals. While presumed to be ubiquitous in built and natural environments, NTM environmental studies are limited. While environmental sampling campaigns have been performed in geographic areas of high NTM disease burden, NTM species diversity is less defined among areas of lower disease burden like Colorado. In Colorado, metals such as molybdenum have been correlated with increased risk for NTM infection, yet environmental NTM species diversity has not yet been widely studied. Based on prior regression modeling, three areas of predicted high, moderate, and low NTM risk were identified for environmental sampling in Colorado. Ice, plumbing biofilms, and sink tap water samples were collected from publicly accessible freshwater sources. All samples were microbiologically cultured and NTM were identified using partial rpoB gene sequencing. From these samples, areas of moderate risk were more likely to be NTM positive. NTM recovery from ice was more common than recovery from plumbing biofilms or tap water. Overall, nine different NTM species were identified, including clinically important Mycobacterium chelonae. MinION technology was used to whole genome sequence and compare mutational differences between six M. chelonae genomes, representing three environmental isolates from this study and three other M. chelonae isolates from other sources. Drug resistance genes and prophages were common findings among environmentally derived M. chelonae, promoting the need for expanded environmental sampling campaigns to improve our current understanding of NTM species abundance while opening new avenues for improved targeted drug therapies.

RESUMO

Democratizing genomic data science, including bioinformatics, can diversify the STEM workforce and may, in turn, bring new perspectives into the space sciences. In this respect, the development of education and research programs that bridge genome science with "place" and world-views specific to a given region are valuable for Indigenous students and educators. Through a multi-institutional collaboration, we developed an ongoing education program and model that includes Illumina and Oxford Nanopore sequencing, free bioinformatic platforms, and teacher training workshops to address our research and education goals through a place-based science education lens. High school students and researchers cultivated, sequenced, assembled, and annotated the genomes of 13 bacteria from Mars analog sites with cultural relevance, 10 of which were novel species. Students, teachers, and community members assisted with the discovery of new, potentially chemolithotrophic bacteria relevant to astrobiology. This joint education-research program also led to the discovery of species from Mars analog sites capable of producing N-acyl homoserine lactones, which are quorum-sensing molecules used in bacterial communication. Whole genome sequencing was completed in high school classrooms, and connected students to funded space research, increased research output, and provided culturally relevant, place-based science education, with participants naming three novel species described here. Students at St. Andrew's School (Honolulu, Hawai'i) proposed the name Bradyrhizobium prioritasuperba for the type strain, BL16AT, of the new species (DSM 112479T = NCTC 14602T). The nonprofit organization Kauluakalana proposed the name Brenneria ulupoensis for the type strain, K61T, of the new species (DSM 116657T = LMG = 33184T), and Hawai'i Baptist Academy students proposed the name Paraflavitalea speifideiaquila for the type strain, BL16ET, of the new species (DSM 112478T = NCTC 14603T).

RESUMO

BACKGROUND: Aspirin exacerbated respiratory disease (AERD) in patients who have had sinus surgery remains a management challenge. Aspirin desensitization and biologics are additional treatment options. It remains unclear if patients require a more comprehensive surgery prior to implementing such additional therapies. The purpose of this study was to quantify prior surgery completeness in AERD patients at a tertiary rhinology practice. METHODS: Paranasal sinus CT scans were reviewed by four academic rhinologists to assess surgery completeness. Using a published CT grading system, each sinus was graded on the completeness of surgery and middle turbinate reduction. A score out of 14 was calculated for each patient (7 per side). RESULTS: Sixty-one patients with AERD out of 141 available were included. Mean inter-rater agreement across all sinuses was moderate (k = 0.42). The mean completeness score was 6.7/14. The following procedures were rated as complete (means): uncinectomy (L: 84%, R: 82%, k = 0.44), maxillary (L: 83%, R: 77%, k = 0.32), middle turbinate reduction (L: 45%, R: 46%, k = 0.31), anterior ethmoid (L: 35%, R: 39%, k = 0.51), sphenoid (L: 36%, R: 35%, k = 0.4), posterior ethmoid (L: 30%, R: 30%, k = 0.48), frontal (L: 22%, R: 21%, k = 0.46). CONCLUSION: Prior surgery in AERD patients were mostly deemed incomplete. Uncinectomy and maxillary antrostomy are the most common procedures previously performed. It remains toe seen whether this would be considered 'adequate' surgery or more 'complete' surgery is required to achieve greater disease control.

RESUMO

As environmental opportunistic pathogens, nontuberculous mycobacteria (NTM) can cause severe and difficult to treat pulmonary disease. In the United States, Hawai'i has the highest prevalence of infection. Rapid growing mycobacteria (RGM) such as Mycobacterium abscessus and M. porcinum and the slow growing mycobacteria (SGM) including M. intracellulare subspecies chimaera are common environmental NTM species and subspecies in Hawai'i. Although iron acquisition is an essential process of many microorganisms, iron acquisition via siderophores among the NTM is not well-characterized. In this study, we apply genomic and microbiological methodologies to better understand iron acquisition via siderophores for environmental and respiratory isolates of M. abscessus, M. porcinum, and M. intracellulare subspecies chimaera from Hawai'i. Siderophore synthesis and transport genes, including mycobactin (mbt), mmpL/S, and esx-3 were compared among 47 reference isolates, 29 respiratory isolates, and 23 environmental Hawai'i isolates. Among all reference isolates examined, respiratory isolates showed significantly more siderophore pertinent genes compared to environmental isolates. Among the Hawai'i isolates, RGM M. abscessus and M. porcinum had significantly less esx-3 and mbt genes compared to SGM M. chimaera when stratified by growth classification. However, no significant differences were observed between the species when grown on low iron culture agar or siderophore production by the chrome azurol S (CAS) assay in vitro. These results indicate the complex mechanisms involved in iron sequestration and siderophore activity among diverse NTM species.

RESUMO

Nontuberculous mycobacteria (NTM) are ubiquitous environmental opportunistic pathogens that can cause chronic lung disease. Within the United States, Hawai'i has the highest incidence of NTM lung disease, though the precise reasons are yet to be fully elucidated. One possibility is the high prevalence of NTM in the Hawai'i environment acting as a potential reservoir for opportunistic NTM infections. Through our previous initiatives to collect and characterize NTM in Hawai'i, community scientists of Hawai'i have collected thousands of environmental samples for sequencing. Here, these community scientists were invited for the first time into a high school lab in O'ahu for a genomic sequencing workshop, where participants sequenced four of the collected isolate genomic samples using the Oxford Nanopore Technologies MinION sequencer. Participants generated high quality long read data that when combined with short read Illumina data yielded complete bacterial genomic assemblies suitable for in-depth analysis. The gene annotation analysis identified a suite of genes that might help NTM thrive in the Hawai'i environment. Further, we found evidence of co-occurring methylobacteria, revealed from the sequencing data, suggesting that in some cases methylobacteria and NTM may coexist in the same niche, challenging previously accepted paradigms. The sequencing efforts presented here generated novel insights regarding the potential survival strategies and microbial interactions of NTM in the geographic hot spot of Hawai'i. We highlight the contributions of community scientists and present an activity that can be reimplemented as a workshop or classroom activity by other research groups to engage their local communities.

RESUMO

Objective: To understand the factors contributing to gender disparities in the research productivity of Canadian academic otolaryngologist-head and neck surgeons. Methods: Publicly available sources including departmental websites, SCOPUS, and the Royal College of Physicians and Surgeons of Canada were accessed between February and April 2022 to analyze gender differences in the academic productivity of otolaryngologist-head and neck surgeons across Canada. Gender differences in research productivity metrics, including h-index, i10-index, publication number, and number of first and senior authorships were assessed. Demographic data, including gender, institution, years in practice, and leadership roles were assessed for correlation with increased research productivity. Subgroup analyses were used to evaluate gender differences in productivity metrics, and univariable and multivariable regression analyses were used to evaluate predictors of research productivity. Results: Data were collected for 316 academic otolaryngologists (252 men, 64 women, P < .001). Men had significantly more years of publishing [mean (standard deviation, SD), 15.64 (9.45) vs 12.44 (8.28), P = .014], higher h-indices [12.22 (11.47) vs 7.33 (5.36), P < .001], i10-indices [22.61 (37.88) vs 8.17 (9.14), P > .001], publication numbers [46.63 (65.18) vs 19.59 (23.40), P < .001], and first [8.18 (9.95) vs 4.89 (6.18), P = .001] and senior authorships [12.98 (22.72) vs 3.83 (6.89), P < .001]. Gender differences were most pronounced in head and neck oncology, pediatrics, and the late career stage. Gender disparities in productivity were absent in the early career stage. Multivariate analysis identified only the number publications and number of senior author publications as being significantly influenced by gender. Conclusion: Canadian female otolaryngologist-head and neck surgeons appear to have equivalent research productivity to their male counterparts in the early career stage. This mirrors the recent findings in the United States, and demonstrates progress compared to earlier studies that found women to have lower research productivity in the early career stage.

RESUMO

BACKGROUND: Remission, defined as absence of symptoms and objective markers of disease, is emerging as the penultimate goal in the management of several chronic diseases. The concept of remission, well-established in Rheumatology as well as Gastroenterology, is currently emerging in Respiratory Medicine for asthma. It is interesting to consider whether the disease remission concept might successfully be applied to Otolaryngology-Head and Neck Surgery in the management of chronic rhinosinusitis with nasal polyposis (CRSwNP). OBJECTIVE: The purpose of this letter is to explore the evidence supporting the concept of remission under continued medical therapy in chronic rhinosinusitis with nasal polyposis. METHODS: The authors reviewed the literature and summarized studies in chronic rhinosinusitis with nasal polyposis evaluating for evidence of clinical, biochemical, and endoscopic remission. RESULTS: Findings of the studies revealed that endoscopic sinus surgery with continued medical therapy achieved remission in approximately 50% of all patients. CRSwNP patients after primary endoscopic sinus surgery were able to achieve remission in 72% of instances, however this drops to 42% for patients having revision sinus surgery. For CRSwNP patients with co-morbidities such as asthma and aspirin exacerbated respiratory disease, remission rate drops to 23% and 23.5%, respectively compared to non-asthmatic CRSwNP patients who present a remission rate under continued medical therapy of 60%. CONCLUSION: Remission of symptoms and evidence of disease under medical therapy is indeed a concept achievable in patients with CRSwNP, as demonstrated by studies in the literature. Various co-morbidities, notably asthma, apparently influence rate of remission. Better defining this outcome through consensus-based definitions will allow for the development of strategies in CRSwNP care that can help affected patients attain complete relief from clinical, biochemical, and endoscopic markers of CRS with judicious use of medication and surgery. Future efforts will attempt to improve on these outcomes by achieving symptomatic and endoscopic control of disease following cessation of therapy, potentially paving the way towards clinical remission or a 'cure' in CRS.

RESUMO

BACKGROUND: The Canadian landscape of racial diversity in academic OHNS programs is currently unknown, as to date Canadian medical organizing bodies have refrained from collecting race-based data. However, new policy guidelines by the Canadian Medical Association support the collection of data that may be used to support equity, diversity and inclusion programs. This study aims to describe the representation of visible minorities amongst academic OHNS departments and divisions in Canada at various levels of academic seniority. METHODS: An online survey was distributed to members of the 13 academic OHNS department in Canada in 2022. The survey collected demographic data as well as each participant's self-reported race and gender. The primary outcome was the comparison of the racial demographics of Canadian academic OHNS programs to Canadian census data. Secondary outcome measures assessed how demographics varied based on academic position and gender. Simple descriptive statistics were tabulated for all demographic variables. Chi-square goodness of fit analysis was used to compare survey results to anticipated demographics based on 2016 Canadian census data. RESULTS: Of 545 surveys distributed, 224 surveys were completed (response rate of 41%); 67.9% or respondents were male and 32.1% were female. Of these respondents, 71 were residents, 26 lecturers, 54 assistant professors, 39 associate professors, and 34 full professors. There was significantly greater minority representation amongst residents (47.9%), assistant professors (39.6%), and lecturers (40.7%) compared to the Canadian population (25.3%) p < 0.001. Results also showed that there were significantly fewer female lecturers (25.9%, p = 0.01), assistant professors (31.5%, p = 0.006), and full professors (2.9%, p < 0.001) compared to an assumed even proportion of men and women in the population. CONCLUSIONS: Academic OHNS programs in Canada are more racially diverse than the Canadian population. However, women continue to be under-represented in more senior positions, especially women who are visible minorities. Further investigation into the systemic factors that may contribute to this disparity is needed as well as effective ways to promote diversity amongst academic OHNS departments at all levels of academic seniority.

RESUMO

OBJECTIVE: To analyze gender differences in authorship of North American (Canadian and American) and international published otolaryngology-head and neck surgery (OHNS) clinical practice guidelines (CPG) over a 17-year period. METHODS: Clinical practice guidelines published between 2005 and 2022 were identified through the Canadian Agency for Drugs and Technology in Health (CADTH) search strategy in MEDLINE and EMBASE. Studies were included if they were original studies, published in the English language, and encompassed Canadian, American, or international OHNS clinical practice guidelines. RESULTS: A total of 145 guidelines were identified, encompassing 661 female authors (27.4%) and 1756 male authors (72.7%). Among OHNS authors, women and men accounted for 21.2% and 78.8% of authors, respectively. Women who were involved in guideline authorship were 31.0% less likely to be an otolaryngologist compared to men. There were no gender differences across first or senior author and by subspeciality. Female otolaryngologist representation was the greatest in rhinology (28.3%) and pediatrics (26.7%). American guidelines had the greatest proportion of female authors per guideline (34.1%) and the greatest number of unique female authors (33.2%). CONCLUSION: Despite the increasing representation of women in OHNS, gender gaps exist with regards to authorship within clinical practice guidelines. Greater gender diversity and transparency is required within guideline authorship to help achieve equitable gender representation and the development of balanced guidelines with a variety of viewpoints.

RESUMO

INTRODUCTION: Ureteral stents facilitate recovery and avoid external drains in pediatric ureteral reconstruction. Extraction strings avoid the need for a secondary cystoscopy and anesthetic. Due to concerns regarding febrile UTIs in children with extraction strings, we retrospectively assessed the relative risk of UTI in children with extraction strings. OBJECTIVE: Our hypothesis was that stents with extraction strings do not increase the risk of UTI after pediatric ureteral reconstruction. METHODS: Records of all children undergoing pyeloplasty and ureteroureterostomy (UU) from 2014 to 2021 were reviewed. The incidences of UTI, fever, and hospitalization were recorded. RESULTS: 245 patients mean age 6.4 years (163M:82F) underwent pyeloplasty (n = 221) or UU (n = 24). 42% (n = 103) received prophylaxis. Of these, 15% developed UTI versus 5% of those not receiving prophylaxis (p < 0.05). 42 females had prior history of UTI, compared to 20 males (p < 0.05). 49 patients had an extraction string. Stents with extraction strings were removed on average 0.6 months post-op while others underwent cystoscopic removal on average 1.26 months post-op (p < 0.05). 9 (18.4%) required hospitalization for febrile UTI while the stent with extraction string was in place, while only 13 (6.6%) of those without extraction string did (p < 0.02). Of the 9 children with a febrile UTI in the extraction string group, 6 had history of prior UTI (46.1%), compared to only 3 (8.3%) without a prior UTI (p < 0.05). With no prior UTI, there was no difference in UTI risk between those with (3, 8.3%) and without (8, 6.4%) extraction string (p = 0.71). Females with prior UTI and extraction string were more likely to develop UTI than those with prior UTI and no extraction string (p = 0.01). There were not enough males with history of UTI to analyze alone. There were 5 (10%) stent dislodgements in the extraction string group, 2 required further intervention with cystoscopy or percutaneous drainage. DISCUSSION: Extraction strings provide the assurance of drainage while avoiding the need for a second general anesthetic procedure. There is not an increased risk of UTI with extraction string in those without prior history of UTI, but we no longer routinely leave extraction strings if there is history of UTI. CONCLUSION: Children, particularly females, with prior history of UTI have a significantly increased risk of febrile UTIs associated with the use of extraction strings. Prophylaxis does not seem to reduce this risk. Patients with no prior UTI had no higher risk of UTI with extraction string use for pyeloplasty or UU.

RESUMO

PURPOSE: To describe the construction of a novel intraocular snare and evaluate its effectiveness in intraocular foreign body (IOFB) removal. METHOD: This is a retrospective consecutive case series. Five patients underwent pars plana vitrectomy and IOFB removal using the intraocular snare constructed from modified flute needle. RESULTS: All IOFBs were successfully engaged and removed with the snare on the first attempt. Three of the 5 cases (60%) enjoyed good visual outcome (0.4-1.0) postoperatively. No complication related to the use of the snare was encountered in this case series. CONCLUSION: Intraocular foreign body snare is simple, safe, and effective in IOFB removal.

RESUMO

OBJECTIVE: Despite increasing diversity in medical school entrants, disparities exist in academic leadership. This study sought to examine the proportion of women and visible minorities (VMs) among editorial board members (EBMs) of otolaryngology journals. METHODS: Two reviewers collected journal, editorial board, and editor-in-chief characteristics using journal mastheads or official websites. Gender and VM representation on editorial boards and factors associated with increased representation were investigated. RESULTS: Forty-one journals were explored, from January to April 2022. Of 2128 EBMs, 663 (31.3%) were VMs and 551 (25.9%) were women. Editor-in-chief roles were held by 12 (25%) VM individuals and 3 (6.2%) women. Gender differences in the distribution of editorial board positions were found (P < .001); women had higher representation as associate editors (24.5%, n = 551 vs 15.4, n = 1577%) and deputy/managing editors (2.2%, n = 551 vs 0.4%, n = 1577), while men were more represented as editor-in-chief (2.9%, n = 1577 vs 0.5%, n = 551). Similar VM representation existed between genders (31.0% male; 31.6% women) (P = .80). Journal impact factor quartile and gender were significantly correlated (P < .001); a higher proportion of women were represented in the first (27.0% vs 24.5%) and fourth (12.0% vs 4.9%) quartile. No significant factors were identified for higher women's editorial board representation. Larger editorial board size (P = .002) and Asian/South American journals (P = .003 to P < .001) had significantly higher representation of VMs. CONCLUSION: Women and VMs are underrepresented in high-ranking editorial positions. Diversity in editorial boards is needed to ensure fair and balanced journal reviews and equity within otolaryngology.

RESUMO

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.

RESUMO

INTRODUCTION: Children with an isolated fibrolipoma of filum terminale (IFFT) but otherwise normal spinal cord are often evaluated with video urodynamics (VUDS). VUDS interpretation is subjective and can be difficult in young children. These patients may undergo detethering surgery if there is concern for current or future symptomatic tethered cord. OBJECTIVE: We hypothesized that VUDS in children with IFFT would have limited clinical utility regarding decision for or against detethering surgery and VUDS interpretation would have poor interrater reliability. METHODS: Patients with IFFT who underwent VUDS for from 2009 to 2021 were retrospectively reviewed to evaluate clinical utility of VUDS. 6 pediatric urologists who were blinded to patient clinical characteristics reviewed the VUDS. Gwet's first order agreement coefficient (AC1) with 95% CI was used to assess interrater reliability. RESULTS: 47 patients (24F:23M) were identified. Median age at initial evaluation was 2.8yrs (IQR:1.5-6.8). 24 (51%) patients underwent detethering surgery (Table). VUDS at initial evaluation were interpreted by treating urologist as normal in 4 (8%), reassuring for normal in 39 (81%), or concerning for abnormal in 4 (9%). Based on neurosurgery clinic and operative notes for the 47 patients, VUDS made no change in management in 37 patients (79%), prompted detethering in 3 (6%), was given as reason for observation in 7 (15%), and was normal or reassuring for normal but not documented as a reason for observation in 16 (34%) (Table). Interrater reliability for VUDS interpretation had fair agreement (AC1 = 0.27) for overall categorization of VUDS and EMG interpretation (AC1 = 0.34). Moderate agreement was seen for detrusor overactivity interpretation (AC1 = 0.54) and bladder neck appearance (AC1 = 0.46). DISCUSSION: In our cohort, 90% of patients had a normal or reassuring for normal interpretation of VUDS. VUDS interpretation affected clinical course in a minority of patients. There was fair interrater reliability for overall VUDS interpretation and therefore clinical course regarding detethering surgery could vary depending upon interpreting urologist. This fair interrater variability appeared to be related to variability in EMG, bladder neck appearance, and detrusor overactivity interpretation. CONCLUSION: VUDS affected clinical management in about 20% of our cohort and supported the choice for observation in around 50% of patients. This suggests VUDS does have clinical utility in pediatric patients with IFFT. The overall VUDS interpretation had fair interrater reliability. This suggest VUDS interpretation has limitations in determining normal versus abnormal bladder function in children with IFFT. Neurosurgeons and urologists should be aware of VUDS limitations in this patient population.
