ABSTRACT

OBJECTIVES: Understanding the strengths and weaknesses of chatbots as a source of patient information is critical for providers in the rising artificial intelligence landscape. This study is the first to quantitatively analyze and compare four of the most used chatbots available regarding treatments of common pathologies in rhinology. METHODS: The treatment of epistaxis, chronic sinusitis, sinus infection, allergic rhinitis, allergies, and nasal polyps was asked to chatbots ChatGPT, ChatGPT Plus, Google Bard, and Microsoft Bing in May 2023. Individual responses were analyzed by reviewers for readability, quality, understandability, and actionability using validated scoring metrics. Accuracy and comprehensiveness were evaluated for each response by two experts in rhinology. RESULTS: ChatGPT, Plus, Bard, and Bing had FRE readability scores of 33.17, 35.93, 46.50, and 46.32, respectively, indicating higher readability for Bard and Bing compared to ChatGPT (p = 0.003, p = 0.008) and Plus (p = 0.025, p = 0.048). ChatGPT, Plus, and Bard had mean DISCERN quality scores of 20.42, 20.89, and 20.61, respectively, which was higher than the score for Bing of 16.97 (p < 0.001). For understandability, ChatGPT and Bing had PEMAT scores of 76.67 and 66.61, respectively, which were lower than both Plus at 92.00 (p < 0.001, p < 0.001) and Bard at 92.67 (p < 0.001, p < 0.001). ChatGPT Plus had an accuracy score of 4.39 which was higher than ChatGPT (3.97, p = 0.118), Bard (3.72, p = 0.002), and Bing (3.19, p < 0.001). CONCLUSION: On aggregate of the tested domains, our results suggest ChatGPT Plus and Google Bard are currently the most patient-friendly chatbots for the treatment of common pathologies in rhinology.

ABSTRACT

BACKGROUND: Chronic rhinosinusitis (CRS) is common in people with cystic fibrosis (PwCF). Rhinologic symptom prioritization and areas that influence CRS treatment choices, including pursuing endoscopic sinus surgery (ESS), remain understudied. METHODS: Adult PwCF + CRS were enrolled at eight centers into a prospective, observational study (2019-2023). Participants were administered the 22-SinoNasal Outcome Test (SNOT-22) survey and a modified SNOT-22 instrument examining symptom importance. We determined importance rankings for individual symptoms and SNOT-22 symptom importance subdomains in two sets of subgroups-those pursuing ESS versus continuing medical management (CMT), and those on elexacaftor/tezacaftor/ivacaftor (ETI) versus not on ETI. RESULTS: Among 69 participants, the highest priorities were nasal congestion (n = 48, 69.6% important), post-nasal discharge (32, 46.4%), facial pain (29, 43.3%), waking up tired (27, 39.1%), and fatigue (26, 37.7%). Those electing surgery (n = 23) prioritized sleep and psychological dysfunction symptoms compared to those pursuing CMT (n = 49) (sleep median score = 19.0 [interquartile range: 12.0, 25.0] vs. 4.5 [0.0, 12.8]; p < 0.0001; psychological = 17.0 [7.0, 26.0] vs. 7.0 [0.0, 15.8]; p = 0.002). ETI users had comparable SNOT-22 total symptom importance scores to non-ETI users (p = 0.14). Non-ETI users (n = 34) showed a trend toward prioritizing sleep symptoms compared to ETI users (n = 35) (13.0 [2.8, 22.3] vs. 6.0 [2.0, 17.0]; p = 0.055). CONCLUSIONS: Nasal congestion and post-nasal discharge were top priorities reported by PwCF + CRS. Those electing surgery prioritized sleep and psychological symptoms, highlighting their importance in pre-operative discussions. Non-ETI users' prioritization of sleep improvement may highlight their unique disease impact and therapeutic needs; however, additional investigation is required.

ABSTRACT

BACKGROUND: It is unclear whether chronic rhinosinusitis (CRS) endotypes show a differential response to endoscopic sinus surgery (ESS). We explored patient mucous inflammatory cytokine expression and associations with patient-reported and clinically measured post-operative outcome measures. METHODS: Patients with CRS were prospectively recruited between 2016 and 2021 into a national multicenter, observational study. Mucus was collected from the olfactory cleft preoperatively and evaluated for 26 biomarkers using cluster analysis. Patient-reported outcome measures included the 22-item Sino-Nasal Outcome Test (SNOT-22) and Questionnaire of Olfactory Dysfunction (QOD). Additional clinical measures of disease severity included threshold, discrimination, and identification (TDI) scores using "Sniffin' Sticks" testing and Lund-Kennedy endoscopic score (LKES). RESULTS: A total of 115 patients were clustered into type 2 inflammatory, non-type 2 inflammatory, noninflammatory, and two indeterminate clusters based on individual protein levels. Overall, the type 2 inflammatory cluster was found to have the highest mean improvement in both SNOT-22 (-28.3 [standard deviation, ±16.2]) and TDI (6.5 [standard deviation, ±7.9]) scores 6 months after ESS. However, on average, all endotype clusters demonstrated improvement in all outcome measures after ESS without statistically significant between-group differences in SNOT-22 (p = 0.738), QOD (p = 0.306), TDI (p = 0.358), or LKES (p = 0.514) measures. CONCLUSIONS: All CRS endotype clusters responded favorably to surgery and showed improvements in patient-reported and objective outcome measures. Thus, ESS should be considered a more generalized CRS therapy, and benefits appear to not be limited to specific endotypes.

ABSTRACT

Allergic rhinitis (AR) is associated with increased sleep disturbances in adults and children. Pathogenesis is multifactorial, with nasal obstruction playing a large role. Intranasal corticosteroids, antihistamines, leukotriene inhibitors, and allergen immunotherapy have been demonstrated to relieve self-reported symptoms of sleep impairment. Given the high prevalence of sleep impairment in AR, providers should consider evaluating any patient with AR for sleep disturbances and sleep-disordered breathing.

ABSTRACT

Cichlid fishes are an important model system in evolutionary biology, primarily because of their exceptional diversity. However, while some cichlid assemblages, such as the ones of the African Great Lakes, have received considerable attention, others are not well studied, including many riverine species. Here, we focus on the Australoheros autrani species group and first report a new record of Australoheros in the upper Paranaíba River drainage, extending the known distribution range of this genus. Through Bayesian inference and maximum likelihood phylogenetic analyses of the mitochondrial cytochrome b gene of these specimens as well as available sequences, we assigned the newly discovered population to Australoheros barbosae. We corroborate the monophyly of the A. autrani species group and the presence of three species in the upper/middle Paraíba do Sul River basin as well as molecular diagnostic characters for each. Finally, we provide evidence for a recent expansion of A. barbosae. Supplementary Information: The online version contains supplementary material available at 10.1007/s10228-022-00888-9.

ABSTRACT

BACKGROUND: The association of gustatory dysfunction (GD) with quality of life (QOL) and cognition in older adults is understudied. Our objective was to study the prevalence of GD in the community and explore impacts and associated factors. METHODS: A prospective, multi-institutional, pre-corona virus disease (COVID) cohort of adults aged 50 years and older had smell and taste testing using "Sniffin' Sticks" (TDI) and "Taste Strips." The impact of GD on mood, QOL, and social interaction was assessed through visual analog scales. Subjects completed the Questionnaire of Olfactory Disorders, Patient Health Questionnaire 9, Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment, and the DeJong scale of loneliness. RESULTS: A total of 48 patients, average age of 54.7 years, were enrolled. Thirty-two percent experienced GD on taste strips, and 62% experienced olfactory dysfunction (OD) on TDI. Almost 30% (29.5%) had both GD and OD. GD and OD correlated with worsened cognitive function on MMSE (r = 0.392 and 0.05, p = 0.018 and 0.003). Subjects with both GD and OD had worse MMSE than either alone (p = 0.003). Dry mouth and difficult chewing correlated with GD (r = -0.37 and -0.31, p = 0.10 and 0.37). Self-reported GD and OD were correlated (r = 0.46, p = 0.001), as were psychophysical GD and OD (r = 0.394, p = 0.008). GD did not correlate with other metrics. CONCLUSION: Thirty-two percent of subjects experienced GD on psychophysical testing, yet most are unaware without impacts on daily life. However, GD correlates with worsened cognitive function. Taste testing may play a role in screening of neurocognitive decline, and multisensory dysfunction may indicate of worsened cognitive states.

ABSTRACT

BACKGROUND: Productivity loss and activity limitations due to chronic rhinosinusitis (CRS) are known to contribute to the significant economic and personal burden of disease. The purpose of this study was to assess productivity and activity impairment before and after endoscopic sinus surgery (ESS) for medically refractory CRS. METHODS: This investigation was a prospective, multi-institutional, observational cohort study. Patients diagnosed with medically refractory CRS completed the Work Productivity and Activity Impairment-Specific Health Problem (WPAI-SHP) questionnaire before surgery and approximately 6 months after the procedure. Factors associated with minimal clinical important differences (MCIDs) for productivity and activity impairment were identified. RESULTS: A total of 279 study participants were screened for inclusion, of whom 176 (63.1%) with postoperative follow-up were included in the final cohort. Preoperative productivity and activity impairment were observed in 63.2% and 69.8% of the patients, respectively. Among these patients, postoperative improvement equaling at least 1 MCID was reported in both productivity (76.1%) and activity (76.4%) impairments. Multivariate regression identified sphenoidotomy (odds ratio [OR], 4.18; 95% confidence interval [CI], 1.03-17.02) as the only factor associated with increased likelihood of productivity improvement, whereas septoplasty during ESS (OR, 8.45; 95% CI, 2.33-30.68) and migraine (OR, 0.35; 95% CI, 0.12-0.96) were associated with differential odds of activity improvement. CONCLUSION: CRS is associated with a substantial burden on productivity and activity that significantly improves after treatment with ESS. These data may facilitate improved patient counseling and shared decision-making regarding surgical management for CRS.

ABSTRACT

BACKGROUND: Primary immunodeficiency disorders (PIDDs) may be a risk factor for development of recurrent acute rhinosinusitis (RARS). There are currently no clear guidelines for the timing and methodology of PIDD testing in patients with RARS. The aim of this scoping review is to identify and analyze existing literature on this topic. METHODS: A scoping review was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR) guidelines. Articles addressing recurrent acute sinusitis and immunodeficiencies were collected from PubMed, Web of Science, and the Cumulative Index to Nursing and Allied Health Literature (CINAHL) and systematically evaluated for eligibility by two reviewers. RESULTS: Of the 209 unique articles identified, 11 met criteria for review and analysis. Articles consisted of historical cohort, case-control, and cross-sectional studies, in addition to case series and nonsystematic reviews. The majority (10) recommended immunodeficiency testing, consisting of general immunologic screening (3), quantitative immunoglobulins (6), and postvaccination antibody titers (5). There was an emphasis on immunoglobulin G (IgG) subclass testing (6). Of the eight articles providing timing recommendations, the majority recommended testing after recurrent infections or diagnosis (6); however, criteria for diagnosis of RARS and populations targeted by recommendations varied greatly by article. CONCLUSION: Current literature on RARS emphasizes immunoglobulin quantification and postvaccination antibody titers to evaluate for PIDD after diagnosis, but recommendations are limited by wide-ranging populations of interest and inconsistent definitions. This scoping review identified a lack of evidence-based articles specific to diagnostic workup for PIDD in patients with RARS, and additional research with standardized definitions and focus on RARS is necessary to guide clinical practice.

ABSTRACT

Catfishes of the genus Trichomycterus comprise the most diverse fish group in mountain river basins crossing the Atlantic Forest of south-eastern Brazil, with a great concentration of species in the Rio Paraíba do Sul basin. The present study is directed to the T. nigroauratus group, endemic to the Rio Paraíba do Sul basin, comprising species commonly found associated with bottom leaf litter. Field studies revealed two sympatric, distinct colour morphs, one comprising small specimens with a black longitudinal stripe over a pale brown ground colour on the flank and another comprising a single larger specimen with small dark browns spots scattered over a pale-yellow ground colour. These specimens were found in the upper Rio Paraitinga drainage, an area disjunct from the area inhabited by the other species of the group. We performed coalescent single-locus analyses for species delimitation using a cytochrome b fragment (1088 bp) for specimens from eight localities, including sequences taken from specimens exhibiting different colouration morphs and topotypes of all the three nominal species of the T. nigroauratus group. The analyses supported the two colouration morphs as belonging to a single species that is herein described. It is distinguished from other congeners by its unique colour pattern, dorsal and anal fins fin more posteriorly placed, and by the morphology of the opercle, metapterygoid and pelvic bone. The Maximum Likelihood analysis indicated the new species as sister to a clade containing all other congeners of the group, which is corroborated by osteological data. The occurrence of different lineages in neighbouring areas of the upper Rio Paraíba do Sul basin is interpreted as a possible vestige of a past complex paleogeographical scenario during the Cenozoic. The present record of striking ontogenetic colouration change, revealed only after checking DNA sequences of individuals exhibiting different colouration phenotypes, again highlights the importance of combining morphological and molecular data in taxonomical studies.

ABSTRACT

OBJECTIVE: Journal clubs are a fundamental part of medical training that allow residents and faculty to critically analyze literature, keep up-to-date with new advancements, and implement evidence-based medicine. The aim of this study was to describe one otolaryngology residency program's efforts towards reformatting its journal club, evaluate how well the re-designed format enabled participants to achieve journal club goals compared to the prior format, and assess faculty and resident qualitative perceptions of both formats. DESIGN: An 11-question survey was sent to all department faculty and residents to obtain feedback regarding the original journal club format. The results of this initial survey were then used to redesign the journal club format, which consisted of 3 rotating session types: evidence-based, deep-dive, and landmark. A 6-month pilot program using the redesigned format was implemented, and surveys were sent at the halfway mark and at the conclusion of the pilot to evaluate the effectiveness of these format changes. SETTING: A single academic center with an otolaryngology residency program PARTICIPANTS: : Residents and faculty in the department of otolaryngology RESULTS: Compared to the original format, the 6-month pilot demonstrated a more consistent attainment of journal club goals and a near-unanimous preference for the new format. This preference was consistent among both faculty (90.9%) and residents (89%). All respondents agreed that the intended goals of journal club were more frequently met under the revamped format, and statistically significant differences in approval rate were observed in the specific areas of critically assessing the literature, highlighting new findings, and translating forefront knowledge. The overall time required to prepare for sessions was lower for faculty, and higher for residents. CONCLUSIONS: The findings from this study help to support programmatic efforts towards redesigning journal clubs with the goals of improving participant satisfaction and educational benefit. With the paucity of data in the literature evaluating journal club format overhauls, this study provides compelling evidence for programs to perform similar assessments and consider redesigns if warranted.

ABSTRACT

BACKGROUND: Alcohol hypersensitivity (AH), an exacerbation of respiratory symptoms in response to alcohol consumption, is common in aspirin-exacerbated respiratory disease and other forms of chronic rhinosinusitis (CRS). We speculated that these reactions relate to the activation of innate immune cells including basophils and, in particular, platelet-adherent basophils by polyphenolic compounds contained within eliciting alcoholic beverages. OBJECTIVE: We investigated the absolute numbers of these cells in patients with AH and the ability of relevant polyphenolic compounds to cause cellular activation. METHODS: Data were collected from 412 consecutive adults presenting to a tertiary care sinonasal clinic in whom the presence of AH was elicited. The CRS phenotype was determined and results from complete blood cell count and differential were analyzed. A subset of patients was invited to donate blood samples that were used to explore the ability of relevant compounds associated with alcohol consumption to activate platelet-nonadherent and platelet-adherent basophils. Activation was quantified by flow cytometry as up-regulated expression of CD63 and as secretion of lipid metabolites. RESULTS: Of the 412 patients enrolled, 69 (16.7%) endorsed having AH. Significantly higher platelet counts were seen in patients reporting AH. Red wine extract and several polyphenolic compounds produced basophil activation and this was primarily observed among platelet-adherent basophils. Platelet activation was further established as the release of thromboxane B2. CONCLUSION: The presence of AH is associated with significantly higher platelet levels and compounds present in alcoholic beverages can directly mediate both their activation and the activation of platelet-adherent basophils.

ABSTRACT

BACKGROUND: Viral infections, especially those caused by rhinovirus, are the most common cause of asthma exacerbations. Previous studies have argued that impaired innate antiviral immunity and, as a consequence, more severe infections contribute to these exacerbations. OBJECTIVE: These studies explored the innate immune response in the upper airway of volunteers with allergic rhinitis and asthma in comparison to healthy controls and interrogated how these differences corresponded to severity of infection. METHODS: Volunteers with allergic rhinitis, those with asthma, and those who are healthy were inoculated with rhinovirus A16 and monitored for clinical symptoms. Tissue and nasal wash samples were evaluated for antiviral signature and viral load. RESULTS: Both subjects with allergic rhinitis and asthma were found to have more severe cold symptoms. Subjects with asthma had worsened asthma control and increased bronchial hyperreactivity in the setting of higher fractional exhaled breath nitric oxide and blood eosinophils. These studies confirmed reduced expression of interferons and virus-specific pattern recognition receptors in both cohorts with atopy. Nevertheless, despite this defect in innate immunity, volunteers with allergic rhinitis/asthma had reduced rhinovirus concentrations in comparison to the controls. CONCLUSION: These results confirm that the presence of an allergic inflammatory disorder of the airway is associated with reduced innate immune responsive to rhinovirus infection. Despite this, these volunteers with allergy have reduced viral loads, arguing for the presence of a compensatory mechanism to clear the infection.

ABSTRACT

OBJECTIVE: The Food and Drug Administration and the National Institutes of Health (NIH) have asserted that diverse demographic representation in clinical trials is essential. In light of these federal guidelines, the objective of this study is to assess the racial, ethnic, and gender demographics of patients enrolled in clinical trials registered with the NIH that evaluate chronic rhinosinusitis with nasal polyposis (CRSwNP) relative to the demographics of the US population. STUDY DESIGN: Cross-sectional study. SETTING: Not applicable. METHODS: ClinicalTrials.gov was queried to identify all prospective clinical trials for CRSwNP. Individual study and pooled data were compared with national US census data. RESULTS: Eighteen studies were included comprising 4125 patients and evaluating dupilumab, mepolizumab, omalizumab, fluticasone/OptiNose, MediHoney, mometasone, and SINUVA. Women constituted 42.7% of clinical trial participants. Of the 4125 participants, 69.6% identified as White, 6.6% as Black, 20.8% as Asian, 0.1% as Pacific Islander, 0.4% as American Indian, 8.0% as Hispanic, and 2.4% as other. The racial, ethnic, and gender composition of the pooled study population differs significantly from national US census data, with underrepresentation of Black, Hispanic, Pacific Island, and American Indian individuals, as well as females (P < .05). CONCLUSION: The racial, ethnic, and gender demographics of patients enrolled in CRSwNP clinical trials registered with the NIH differ significantly from the demographics of the US population, despite federal guidelines advising demographically representative participation. Proactive efforts to enroll participants that better represent anticipated treatment populations should be emphasized by researchers, institutions, and editorial boards.

ABSTRACT

Posttreatment imaging evaluation of sinuses encompasses a wide gamut of procedures, ranging from endoscopic procedures for sinonasal inflammatory diseases to markedly radical surgeries for malignant neoplasms (with or without reconstructions), as well as providing access for surgeries involving the anterior and central skull base. Advances in both techniques and devices have expanded the use of endoscopic approaches in managing both benign and malignant lesions, in addition to being the primary surgical method for treating all medically refractive sinonasal inflammatory disorders. Familiarity with the complex anatomy in the sinonasal region and knowledge of the various procedures is indispensable in interpreting these imaging studies.

ABSTRACT

BACKGROUND: The Questionnaire of Olfactory Disorders-Negative Statements (QOD-NS) is a 17-item instrument measuring olfactory-specific quality of life (QOL). However, in clinical research patients can be overwhelmed with multiple questionnaires. We recently developed the 7-item brief QOD-NS (B-QOD). Our objective was to evaluate the psychometric properties of the B-QOD in both the development (D) sample, and in a separate replication (R) sample. METHODS: Testing on D (n = 203) and R (n = 281) samples included initial exploratory factor analysis (EFA), followed by internal reliability, information loss, and confirmatory factor analysis (CFA). Finally, incremental predictive utility analysis (IPUA) was performed by correlating the B-QOD with the 22-item Sino-Nasal Outcome Test (SNOT-22) survey. RESULTS: EFAs of both D and R demonstrated an underlying single-factor structure (eigenvalue = 4.17 and 3.57, respectively) with comparable loading factors (R > 0.30 for both). B-QOD also had good internal reliability in both D and R (Cronbach's alpha = 0.88 and 0.83, respectively). Also, there is minimal information loss with B-QOD compared to QOD-NS in both D and R (R = 0.98 and 0.96, respectively). CFA indicates that the B-QOD single-factor model has good overall fit as measured by the Comparative Fit Index (CFI) and the Standardized Root Mean Squared Residuals (SRMSR) in the D and R samples (CFI = 0.99 and 0.97; SRMSR = 0.035 and 0.053). IPUA shows that the QOD-NS offers no additional predictive benefit of SNOT-22 scores when compared with B-QOD. CONCLUSION: The 7-item B-QOD captures a structurally coherent and reliable single dimension, with minimal information loss and excellent external predictive utility when compared to the QOD-NS.

ABSTRACT

BACKGROUND: Multiple hypotheses are evolving that suggest several, potentially overlapping etiologies for olfactory dysfunction (OD) in chronic rhinosinusitis (CRS). Understanding inflammatory cytokine profiles of the olfactory cleft (OC) and their association with olfactory function is foundational for future clinical care and research. METHODS: This cross-sectional, case-control study evaluates associations among OC mucus inflammatory proteins, psychophysical olfactory testing, and computed tomography (CT) analysis of the OC and sinuses. Normative reference intervals were determined for each protein and odds ratios (ORs) were used to compare proportions of altered expression between CRS without nasal polyposis (CRSsNP) and CRS without nasal polyposis (CRSwNP). RESULTS: Case subjects with CRS (n = 151) and controls (n = 74) were evaluated. A majority of OC proteins tested were found within detectable ranges for cases and controls. The CRS cohort had significantly higher concentrations for 23 of 26 proteins. CRS cases with abnormal levels of C-C motif chemokine ligand 2 (CCL2), CCL3, interleukin 5 (IL5), IL10, and IL13 associated with greater olfactory deficits. The prevalence of elevated IL5 and IL13 in anosmic patients was 64.6% and 62.5%, respectively (p < 0.004). CRS cases with the highest odds of elevated expression in CRSwNP were IL5 (OR = 10.83) and IL13 (OR = 8.36). However, both IL5 and IL13 were still elevated in approximately 14% of CRSsNP patients. The highest magnitude of correlation between the total percent of OC opacification was found to be with IL5 (r = 0.543; p < 0.001), whereas other moderate correlations were noted with immunoglobulin E (IgE), IL10, and IL13. CONCLUSION: This study confirmed that OC inflammatory proteins vary both by disease phenotype and in their association with OD. Type 2 inflammatory mediators are increased in CRS, especially within the CRSwNP group. However, a substantial proportion of CRSsNP also express type 2 inflammatory mediators. Further research is necessary to understand the complex roles OC mucous inflammatory proteins might play in defining endotype and in impacting CRS-related OD. ©2021 ARSAAOA, LLC.
