The Voice-related Experiences of Nonbinary Individuals (VENI) is the only published questionnaire exclusively for nonbinary clients. This questionnaire consists of 17 items that gain insight into the client's self-perception of voice and voice-related concerns. According to Shefcik and Tsai (2023), the VENI's content validity is good to excellent. This study evaluated the measure's reliability through internal consistency and test-retest reliability analyses and created impact ratings to support interpretation of scores.</p><p><strong>Study design: </strong>This study utilized an online survey-based design with test-retest administration. The initial survey was administered to evaluate internal consistency and create severity scores. The retest survey was administered 3-5 weeks after the initial survey to evaluate test-retest reliability.</p><p><strong>Methods: </strong>Fifty-five nonbinary participants with a desire to modify their voice and who were not receiving gender-affirming communication services completed the first survey. Respondents completed the VENI and self-reported the degree that their voice adversely impacts their daily life. Internal Consistency Coefficient (ICC) and item total correlations (ITC) were used to evaluate internal consistency. Thirty participants from the initial survey retook the VENI after 3-5 weeks. Intraclass correlation coefficient (ICCC), Pearson's r, and standard error of measurement (SEM) were used to evaluate test-retest reliability.</p><p><strong>Results: </strong>ICC was α = 0.85 and ITCs ranged between r = 0.11 and 0.72. Severity scores were created through standard deviations from the mean, resulting in five classifications from \"mild\" to \"severe.\" Comparison of VENI scores between test and retest resulted in Pearson's r = 0.89, P =< 0.001, SEM = 3.03, and the ICCC for the measure was 0.88.</p><p><strong>Conclusion: </strong>The VENI has good internal consistency and strong test-retest reliability. Clients' VENI scores can be interpreted using the SEM and impact rating classifications derived from the sample analyzed in this study.

The Anti-IgLON5 disease is under-recongnized in the field of otolaryngology. Therefore, the aim of this systematic review is to summarize the current literature on airway management in Anti-IgLON5 disease, a potentially life-threatening condition, and present two cases that highlight the critical importance of early recognition and intervention for laryngeal symptoms. A comprehensive search of PubMed/MEDLINE for studies related to Anti-IgLON5 and respiratory complications was conducted, focusing on articles published before September 13, 2024. Cases involving airway presentation and management were included. The literature review included 16 articles yielded 28 patients, revealing that 78.5% required tracheotomy due to respiratory failure or laryngeal symptoms. Dysphagia and obstructive sleep apnea were the most common presenting symptoms of the disease. Bilateral vocal cord (VC) paralysis was observed in 67% of cases, though it often developed later in the disease course. The two case reports align with these findings, illustrating that early tracheotomy may be necessary to prevent sudden death, even in patients with initial VC mobility. Anti-IgLON5 disease can lead to severe airway compromise, necessitating early intervention. Regular otolaryngological evaluation and polysomnography are critical in managing these patients, and tracheotomy should be considered a key preventive measure against respiratory failure. Awareness of IgLON5 antibodies as a differential diagnosis in patients presenting with unexplained laryngeal symptoms is essential for timely intervention.</p>","PeriodicalId":49954,"journal":{"name":"Journal of Voice","volume":" ","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143765603","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
