Formation of left-handed helices by C2'-fluorinated nucleic acids under physiological salt conditions.

Recent findings in cell biology have rekindled interest in Z-DNA, the left-handed helical form of DNA. We report here that two minimally modified nucleosides, 2'F-araC and 2'F-riboG, induce the formation of the Z-form under low ionic strength. We show that oligomers entirely made of these two nucleosides exclusively produce left-handed duplexes that bind to the Zα domain of ADAR1. The effect of the two nucleotides is so dramatic that Z-form duplexes are the only species observed in 10 mM sodium phosphate buffer and neutral pH, and no B-form is observed at any temperature. Hence, in contrast to other studies reporting formation of Z/B-form equilibria by a preference for purine glycosidic angles in syn, our NMR and computational work revealed that sequential 2'F…H2N and intramolecular 3'H…N3' interactions stabilize the left-handed helix. The equilibrium between B- and Z- forms is slow in the 19F NMR time scale (≥ms), and each conformation exhibited unprecedented chemical shift differences in the 19F signals. This observation led to a reliable estimation of the relative population of B and Z species and enabled us to monitor B-Z transitions under different conditions. The unique features of 2'F-modified DNA should thus be a valuable addition to existing techniques for specific detection of new Z-binding proteins and ligands.

Failure in HiRes Ultra Series Recall Devices Does Not Necessarily Lead to Decrement in Performance.

OBJECTIVE: To understand the impact on speech perception for patients experiencing Advanced Bionics V1 series Ultra and Ultra 3D cochlear implant failure. STUDY DESIGN: Retrospective cohort study. SETTING: Tertiary academic center. PATIENTS: Adult patients implanted with V1 series devices. INTERVENTIONS: Device integrity and speech perception testing. MAIN OUTCOME MEASURES: consonant-nucleus-consonant and AzBio in quiet speech recognition scores. RESULTS: At our institution, 116 V1 series cochlear implants were placed in 114 patients. Thirteen devices in prelingual patients were excluded, leaving 103 (89%) for final analysis. Forty-eight (46.6%) devices were considered as failed using the company provided EFI analysis tool. There were 36 (65.5%) of the remaining 55 devices that consistently tested within normal range; the remainder lost to follow-up with unknown status. Among the 48 device failures, 29 were revised and 19 patients were not revised. Among those not revised, 11 self-opted for observation (57.9%). Observed patients, despite impedance changes meeting failure criteria, had no subjective or objective changes in speech perception. Sentence testing scores for failure patients who elected observation (82.9 ± 11.4%) were significantly higher at failure compared with those opting for revision (55 ± 22.8%, p = 0.006). For those undergoing revision surgery, significant improvement in post-activation scores was noted as compared with time of failure with a mean improvement of 12.9% (p = 0.002, n = 24) for consonant-nucleus-consonant word scores and 17.2% (p = 0.001, n = 19) for AzBio in quiet scores. CONCLUSIONS: Proactive monitoring using EFI identifies a higher rate of Ultra Series V1 device failure than previously reported. However, about 20% of these patients may not have subjective change in hearing or objective decline in test scores and could be observed. Should performance worsen, reimplantation provides significant improvement in speech recognition.

Evaluation of Social Determinants of Health on Dysphagia Care Pathways at a Tertiary Care Facility.

OBJECTIVES: Limited research exists evaluating the impact of social determinants of health in influencing care pathways for patients with dysphagia. A better understanding of whether these determinants correlate to altered care and resource utilization is essential as it relates to patient outcomes. STUDY DESIGN: Retrospective chart review. METHODS: All adult patients seen at a tertiary midwestern hospital were screened for ICD codes of dysphagia diagnoses from 2009 to 2019. Demographic information was collected from these patients with dysphagia including sex, race, ethnicity, and insurance status. Subgroup analysis was performed to assess referral pattern rates and types of diagnostic interventions ordered (none, videofluoroscopic swallow study, esophagram, and esophagogastroduodenoscopy). RESULTS: A total of 31,858 patients with dysphagia were seen at our institution during the study period, with a majority being female (56.36%), Caucasian (79.83%), and publicly insured (63.16%), at a median age of 60.35 years. There were no significant care delivery pattern differences based on geography/zip code analyses. African American patients were significantly more likely to have imaging or interventions performed (odds ratio [OR] 1.463, p = 0.005). Patients with public insurance also had higher rates of diagnostic study utilization (OR 1.53, p = 0.01). Only 3% of all patients with dysphagia were seen by laryngologists. CONCLUSION: No significant differences were seen in dysphagia evaluation modalities based on zip code analyses surrounding this tertiary care facility. African American patients and those with public insurance had significantly higher utilization of subsequent testing and intervention for dysphagia care. Further studies are necessary to delineate causes and outcome differences for these measurable differences in dysphagia care pathways. LEVEL OF EVIDENCE: 4 Laryngoscope, 134:1139-1146, 2024.

Establishment of novel immortalized middle ear cell lines as models for otitis media.

Objective: Otitis media (OM) is among the most frequently diagnosed pediatric diseases in the US. Despite the significant public health burden of OM and the contribution research in culture models has made to understanding its pathobiology, a singular immortalized human middle ear epithelial (MEE) cell line exists (HMEEC-1, adult-derived). We previously developed MEE cultures from pediatric patients with non-inflamed MEE (PCI), recurrent OM (ROM), or OM with effusion (OME) and demonstrated differences in their baseline inflammatory cytokine expression and response to stimulation with an OM-relevant pathogen lysate and cytokines. Herein, we sought to immortalize these cultures and assess retention of their phenotypes. Methods: MEE cultures were immortalized via lentivirus encoding temperature-sensitive SV40 T antigen. Immortalized MEE lines and HMEEC-1 grown in monolayer were stimulated with non-typeable Haemophilus influenzae (NTHi) lysate. Gene expression (TNFA, IL1B, IL6, IL8, MUC5AC, and MUC5B) was assessed by qPCR. Results: Similar to parental cultures, baseline cytokine expressions were higher in pediatric OM lines than in HMEEC-1 and PCI, and HMEEC-1 cells were less responsive to stimulation than pediatric lines. Conclusion: Immortalized MEE lines retained the inflammatory expression and responsiveness of their tissues of origin and differences between non-OM versus OM and pediatric versus adult cultures, supporting their value as novel in vitro culture models for OM.

Factors associated with delayed referral and hearing rehabilitation for congenital sensorineural hearing loss.

OBJECTIVES: To identify the impact of social determinants of health and clinical status on referral and intervention for congenital sensorineural hearing loss. STUDY DESIGN: Retrospective chart review of children with confirmed sensorineural or mixed hearing loss between 2013 and 2021 at a single academic medical institution. METHODS: Referral rates and timing for hearing rehabilitation, rates and timing of completed evaluation, and rate and timing of amplification were recorded. Patient demographics included gestational age, race, ethnicity, sex, hearing loss severity, and CMV status. RESULTS: There were 216 children with confirmed sensorineural or mixed hearing loss, of which 77 had a unilateral hearing loss and 89 a severe or profound hearing loss. Delayed referral for hearing aid evaluation was noted in premature patients (median 375 days premature, median 147 term; p < 0.01) and publicly insured patients (median 215 days, median 123 private; p = 0.04). Delayed time to hearing aid fitting was noted for non-white patients (median 325 days, median 203 white patients; p < 0.01), publicly insured patients (median 309 days, median 212 private insurance; p < 0.02), and premature patients (median 462 days, median 224 term; p = 0.03). White patients were more likely to be referred for cochlear implant (p = 0.03).Privately insured patients and patients with a positive CMV test were more likely to be referred for cochlear implant evaluation, be seen in the cochlear implant clinic, and undergo implantation (p < 0.05). Non-white patients had a delay in cochlear implantation referral (median 928 days, median 398 days white patients; p = 0.05). Prolonged interval between evaluation in cochlear implant clinic to implantation was noted for privately insured patients (median 125 days; median 78 days publicly insured; p = 0.05). CONCLUSIONS: Sociodemographic factors were significantly associated with hearing amplification referral rates and time until amplification for children with identified congenital sensorineural hearing loss. For cochlear implantation, insurance type, CMV status were significantly associated with rate and timing of cochlear implant pathway.

Impacts of Socioeconomic Status on Dentoalveolar Trauma.

INTRODUCTION: Children sustain dentoalveolar trauma and lose teeth at the same rate regardless of socioeconomic status; however, debate surrounds these rates in adults. It is known socioeconomic status plays a major role in access and treatment in health care. This study aims to clarify the role of socioeconomic status as a risk factor for dentoalveolar trauma in adults. METHODS: A single center retrospective chart review took place from January 2011 through December 2020 for patients requiring oral maxillofacial surgery consultation in the emergency department, due to either dentoalveolar trauma (Group 1) or other dental condition (Group 2). Demographic information including age, sex, race, marital status, employment status, and type of insurance were collected. Odds ratios were calculated by chi-square analysis with significance set at P < 0.05. RESULTS: Over the course of 10 years, 247 patients (53% female) required an oral maxillofacial surgery consultation, with 65 (26%) sustaining dentoalveolar trauma. Within this group, there were significantly more subjects who were Black, single, insured with Medicaid, unemployed, and 18 - 39 years old. In the nontraumatic control group, there were significantly more subjects who were White, married, insured with Medicare, and 40 - 59 years old. CONCLUSIONS: Among those seen in the emergency department requiring an oral maxillofacial surgery consultation, those with dentoalveolar trauma have an increased likelihood of being single, Black, insured with Medicaid, unemployed, and 18 - 39 years old. Further research is needed to determine causality and the most critical/influential socioeconomic status factor in sustaining dentoalveolar trauma. Identifying these factors can assist in developing future community-based prevention and educational programs.

The Demographics of Menière's Disease: Selection Bias or Differential Susceptibility?

OBJECTIVE: To clarify whether the reported lack of racial and ethnic diversity among Menière's disease (MD) patients is representative of selection bias or disease susceptibility. STUDY DESIGN: Retrospective medical record review and population-level analyses. SETTING: Tertiary referral center. PATIENTS: Cohort of 1091 patients diagnosed with MD by the tertiary otology service. MAIN OUTCOME MEASURE: Demographic and population-level characteristics (age, sex, race, insurance status, ZIP code, median income, education level) compared with local, regional, health system, and otolaryngology clinic demographics. RESULTS: Patients seen for MD were significantly older than those seen throughout the otolaryngology clinic (median, 65.0 versus 58.8 yr) or health system (65.0 versus 50.8 yr). A majority of patients with MD were of White race (92%), compared with 2.7% Black race and 0.5% Asian. Using population-level data, median income and having medical insurance were significantly correlated with care for MD. A disproportionate rate of care for MD was seen in ZIP codes outside urban areas as compared with other otologic and otolaryngologic conditions seen in the same clinic. CONCLUSION: Patients with MD are of older age, more likely to be of White race, and disproportionately from rural locales. The demographic profile of patients diagnosed with MD by tertiary otology is better explained by differential susceptibility to MD than by selection bias.

Demographic differences in the treatment of unilateral vocal fold paralysis.

Objective: To determine the impact of patient demographics and social determinants of health on treatment pathways for unilateral vocal fold paralysis (UVFP) at a tertiary laryngology clinic. Study design: Retrospective medical record review. Methods: Patient demographics (age, gender, race, ethnicity, and insurance status) were extracted for adults diagnosed with UVFP between 2009 and 2019. Odds ratios for the associations between sociodemographic factors and UVFP treatment pathways were determined by chi-square analyses. Results: A total of 1490 UVFP diagnoses were identified during the study period with the majority being female (58%), White (85%), non-Hispanic (97%), and publicly insured (54%). Five treatment pathways were identified: observation, injection laryngoplasty, voice therapy, laryngeal framework surgery/thyroplasty, and reinnervation surgery. There were 538 patients who underwent observation, 512 injection laryngoplasty, 366 voice therapy, 136 thyroplasty, and 26 laryngeal reinnervation surgery. Males were more likely to undergo injection laryngoplasty than females (OR 1.32; CI 1.08-1.61), whereas females were more likely to undergo voice therapy (OR 1.39; CI 1.09-1.76). Patients with public insurance (OR 1.48; CI 1.03-2.14) and Hispanics (OR 2.60; CI 1.18-5.72) were more likely to undergo thyroplasty. Patients who underwent reinnervation surgery were younger than those in other treatment pathways (median: 39.1 years vs. 50.7-56.1 years). Conclusions: Gender, ethnicity, and insurance status were significantly associated with specific UVFP treatment pathways. Patients with public insurance were more likely to undergo surgical intervention than voice therapy. This data overall supports differences in care pathway utilization for UVFP based on social determinants of health. Level of evidence: Level IV.

Standardization of Outcome Measures for Intratympanic Steroid Treatment for Idiopathic Sudden Sensorineural Hearing Loss.

OBJECTIVE: To identify variability in reported hearing outcomes for intratympanic (IT) steroid treatment of idiopathic sudden sensorineural hearing loss (ISSNHL) by comparing outcomes using the American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) guideline with other published criteria. STUDY DESIGN: Retrospective chart review. SETTING: Tertiary otology practice. PATIENTS: Patients with ISSNHL treated with IT steroid between April 2003 and December 2020. INTERVENTIONS: IT steroid injection and audiometric evaluation. MAIN OUTCOME MEASURES: 1) Rates of full, partial, or no recovery using the AAO-HNS guideline versus other reported criteria, and 2) correlation analyses of demographic and clinical variables with response to IT steroid. RESULTS: Using AAO-HNS reporting criteria, full recovery of the pure-tone average was noted in 25.68% of patients. Applying eight other published outcomes criteria to this patient cohort classified full recovery in 14.87 to 40.54% of patients. Similarly, AAO-HNS criteria classified "no recovery" in 51.35% of our patients, whereas applying the other reported criteria showed an average rate of 62.16% no recovery and as high as 82.43% of patients without recovery. Younger age ( p = 0.003; effect size, 0.924) and IT injection within a week of onset ( p < 0.001; effect size, 1.099) positively correlated with full recovery. There was no impact of prior or concurrent oral steroids, or number of steroid injections on outcome. CONCLUSION: Great variability exists in the literature for assessment of IT steroid outcomes in ISSNHL. Standard reporting of outcomes as per the AAO-HNS SSNHL guideline is recommended to consistently characterize IT steroid efficacy and allow comparison across studies.

Medial orbital wall decompression: Demographics influencing surgical follow-up and complications: Impacts on follow-up and complications.

OBJECTIVE: Identify the impact of demographics and social determinants of health on surgical follow-up and complications after medial orbital wall decompression (MOWD) secondary to thyroid associated orbitopathy (TAO). METHODS: Demographics and social determinants of health (age, sex, race, insurance status) for 46 patients undergoing MOWD secondary to TAO were correlated with post-operative compliance and surgical complications by chi-square analyses. RESULTS: Among 46 patients, 23 were compliant with follow-up. There was no statistically significant difference between compliance and non-compliance based on age (60.25 vs 56.4, p = .41), sex (71.9 % female vs 85.7 % female, p = .31), race (65.6 % white vs 71.4 % white, p = .70) or insurance status (59.4 % private vs 42.9 % private, p = .30). Complications were noted in 50 % of patients of which sinus infection was most common (47.8 % of complications) and epistaxis rare (4.3 % of complications). No correlation was noted between development of complications and compliance (p = .20). Likewise, age, race and insurance status did not correlate with complications. CONCLUSION: For patients undergoing MOWD, no correlations with compliance or complication rate were noted with age, sex, race, or insurance status. A larger cohort may be indicated to identify such patterns. The overall complication rate was 50 % and the increased number of visits may have economic impact. KEY POINTS: This study provides a unique chance to assess demographic correlates of compliance and complication while controlling for surgeon preference. There was no association between sociodemographics and compliance or complications.

Impact of Demographics and Clinical Features on Initial Treatment Pathway for Vestibular Schwannoma.

OBJECTIVE: To identify demographic and clinical features impacting initial treatment pathway for vestibular schwannoma. STUDY DESIGN: Retrospective chart review. SETTING: Tertiary care academic medical center. PATIENTS: Patients diagnosed with vestibular schwannoma between 2009 and 2019. INTERVENTIONS: Observation, stereotactic radiosurgery, or microsurgical resection. MAIN OUTCOME MEASURES: χ 2 Test, one-way analysis of variance, and multivariate logistic regression were used to correlate demographic and clinical factors with initial treatment pathway for 197 newly diagnosed vestibular schwannoma patients. RESULTS: Among 197 patients, 93 (47%) were initially treated with observation, 60 (30%) with stereotactic radiation (Gamma Knife) and 44 (22%) with surgical resection. Age univariately had no statistically significant impact on initial pathway, but those undergoing surgery trended toward a younger demographic (49.1 yr [surgery] versus 57.2 yr [observation] versus 59.0 yr [Gamma Knife]). Men were more likely to be initially observed than women ( p = 0.04). Patients initially observed were more likely to have a lower Koos classification ( p < 0.001) and have better tumor-ear hearing ( p = 0.03). Only 34.4% of patients living outside the local geographic region were initially observed compared with 53.0% living locally ( p = 0.055). Surgeon correlated with initial treatment ( p = 0.04) but did not maintain significance when adjusting for hearing level or tumor size. A multiple linear regression model found age, maximum tumor diameter, and Koos class to correlate with initial treatment pathway ( p < 0.0001, r2 = 0.42). CONCLUSION: Initial treatment pathway for newly diagnosed vestibular schwannoma is impacted by demographic factors such as age, sex, and geographic proximity to the medical center. Clinical features including hearing level and tumor size also correlated with initial treatment modality.

Can Electrocochleography Help Preserve Hearing After Cochlear Implantation With Full Electrode Insertion?

OBJECTIVES: To evaluate the utility of intracochlear electrocochleography (ECochG) monitoring during cochlear implant (CI) surgery on postoperative hearing preservation. STUDY DESIGN: Prospective, randomized clinical trial. SETTING: Ten high-volume, tertiary care CI centers. PATIENTS: Adult patients with sensorineural hearing loss meeting the CI criteria who selected an Advanced Bionics CI. METHODS: Patients were randomized to CI surgery either with audible ECochG monitoring available to the surgeon during electrode insertion or without ECochG monitoring. Hearing preservation was determined by comparing preoperative unaided low-frequency (125-, 250-, and 500-Hz) pure-tone average (LF-PTA) to postoperative LF-PTA at CI activation. Pre- and post-CI computed tomography was used to determine electrode scalar location and electrode translocation. RESULTS: Eighty-five adult CI candidates were enrolled. The mean (standard deviation [SD]) unaided preoperative LF-PTA across the sample was 54 (17) dB HL. For the whole sample, hearing preservation was "good" (i.e., LF-PTA change 0-15 dB) in 34.5%, "fair" (i.e., LF-PTA change >15-29 dB) in 22.5%, and "poor" (i.e., LF-PTA change ≥30 dB) in 43%. For patients randomized to ECochG "on," mean (SD) LF-PTA change was 27 (20) dB compared with 27 (23) dB for patients randomized to ECochG "off" ( p = 0.89). Seven percent of patients, all of whom were randomized to ECochG off, showed electrode translocation from the scala tympani into the scala vestibuli. CONCLUSIONS: Although intracochlear ECochG during CI surgery has important prognostic utility, our data did not show significantly better hearing preservation in patients randomized to ECochG "on" compared with ECochG "off."

Clinical perspectives on nasopharyngeal morphology in humans.

The nasopharynx is an integral component of the upper aerodigestive tract, whose morphologic features share an intimate relationship with a vast array of clinical, functional, and quality of life conditions related to contemporary humans. Its composite architecture and central location amidst the nasal cavity, pharyngotympanic tube, palate, and skull base bears implications for basic physiologic functions including breathing, vocalization, and alimentation. Over the course of evolution, morphological modifications of nasopharyngeal anatomy have occurred in genus Homo which serve to distinguish the human upper aerodigestive tract from that of other mammals. Understanding of these adaptive changes from both a comparative anatomy and clinical perspective offers insight into the unique blueprint which underpins many clinical pathologies currently encountered by anthropologists, scientists, and otorhinolaryngologists alike. This discussion intends to familiarize readers with the fundamental role that nasopharyngeal morphology plays in upper aerodigestive tract conditions, with consideration of its newfound clinical relevance in the era of the COVID-19 pandemic.

Duration of effectiveness of coblation for recurrent epistaxis in hereditary hemorrhagic telangiectasia.

INTRODUCTION: Hereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant disease leading to recurrent epistaxis, telangiectasias, and/or visceral arteriovenous malformations. Multiple treatment methods, including both pharmacologic and surgical, are described to be effective in managing symptomatic HHT. Few report the duration of symptom improvement for each of these treatment methods. This study aims to analyze the duration of effectiveness of coblation treatment for recurrent epistaxis in those with HHT. METHODS: Retrospective single-center chart review was completed for patients diagnosed with HHT who underwent coblation treatment by the same otolaryngologist from December 2009 to November 2021. Demographic information was collected along with whether local Bevacizumab was used during each treatment. Months between treatment coblation sessions was used as a surrogate for duration of treatment effectiveness. Descriptive statistics were used for analysis alongside quantitative statistical analysis. RESULTS: Over the course of 12 years, 57 patients (24 female, 42.11%) with HHT underwent a total number of 150 coblation treatments. The average age at initial coblation was 59 years (29-88) with an average follow-up time of 5 years (1-12 years). Of the 150 coblations, 30 treatments (20%) included bevacizumab injections into the nasal cavity. The average duration of treatment effectiveness across all 150 treatment sessions was 24.5 months (1-87 months). Of the 26 patients (46%) that underwent multiple coblation treatments, the overall average duration of coblation effectiveness was 16.4 months (1-72 mos). When Bevacizumab was utilized, the average duration of effectiveness was 18.3 months (3-62 mos), while the average duration of effectiveness for treatments without Bevacizumab was 15.7 months (1-87 mos, p > 0.251). Further, there was no correlation between duration of treatment effectiveness and age, sex, and race; yet,there was a significant negative correlation between the use of tobacco and duration of coblation effectiveness (p = 0.0202). CONCLUSIONS: Coblation is an effective treatment option for the management of epistaxis in patients with HHT with duration of benefit lasting approximately 2 years. The use of Bevacizumab did not add to the duration of treatment benefit. Further, the duration of benefit was negatively impacted by smoking history.

Analysis of socioeconomic factors in laryngology clinic utilization for treatment of dysphonia.

OBJECTIVE: To evaluate the association between patient socioeconomic and demographic factors and tertiary care utilization for dysphonia in a localized metropolitan area of the American Midwest. METHODS: Multivariate regression analysis was used to correlate patient demographics and population level data (e.g., age, gender, race, insurance, median income, education level) with tertiary laryngology utilization for dysphonia care at our institution between 2000 and 2019. Initial analyses characterized tertiary laryngology utilization rates for all regional ZIP codes and correlated these data with census information for household income and education. Dysphonia patient demographics were compared among populations cared for in our entire academic Otolaryngology department, our health system, and the regional population. RESULTS: Among 1,365,021 patients in our health system, there were 7066 tertiary laryngology visits with a diagnosis of dysphonia. Dysphonia patients as compared to the overall health system were older (62.0 vs. 50.8 years), more likely to be female (63.7 vs. 50.2%) and more likely to have insurance (98.4 vs. 87.5%, all p < .001). Patient and population-level factors including insurance status, education, and black race showed positive correlation with laryngology utilization while median income did not. CONCLUSIONS AND RELEVANCE: Insurance status, education level, and race correlated with utilization of tertiary laryngology services for the evaluation of dysphonia in our community, while median income did not. Black patients utilized tertiary laryngology care at higher rates compared to departmental and regional population utilization data. These results underscore important demographic and disease-specific factors that may affect utilization of subspecialty care in Otolaryngology. LEVEL OF EVIDENCE: IV.

The impact of social determinants of health and clinical comorbidities on post-tympanotomy tube otorrhea.

OBJECTIVES: To measure the impact of social determinants of health and clinical comorbidities on the incidence of post-tympanotomy tube otorrhea (PTTO). METHODS: Retrospective observational cohort study. All children between the ages of 0 and 17 having tympanotomy tube placement between 2009 and 2019. Between group comparisons entailed the calculation of odds ratios (OR) with 95% confidence intervals and associated p-values. RESULTS: Among 12,757 patients who underwent myringotomy and tube placement, 2217 (17.4%) presented with PTTO within 1 year. Race and sex did not correlate with the development of PTTO. Non-Hispanic ethnicity had a negative association with PTTO (OR: 0.80 (0.70-0.91), p < .0001). Insurance status correlated with incidence of PTTO with a higher rate noted among those with public insurance (OR: 1.12 (1.02-1.23), p = .02) and a lower rate among those with private insurance (OR: 0.84 (0.77-0.92), p < .0001). Craniofacial abnormalities had the strongest positive correlation with PTTO, particularly, cleft lip and/or cleft palate (OR>2.24, p < .0001). Immunodeficiency had similar impact on PTTO (OR: 2.38 (1.46-3.91), p < .0001). Asthma and prematurity did not significantly correlate with occurrence of PTTO. CONCLUSION: Higher rates of PTTO correlated strongest with clinical factors; particularly craniofacial abnormalities and immunodeficiency. Social determinants, including private insurance and non-Hispanic ethnicity, were associated with lower rates of PTTO. Race and sex did not show significant correlations.

Abnormal hearing patterns are not associated with endothelium-dependent vasodilation and carotid intima-media thickness: The Framingham Heart Study.

INTRODUCTION: Prior data suggest associations between hearing loss, cardiovascular (CV) risk factors, and CV disease. Whether specific hearing loss patterns, including a strial pattern associated with inner ear vascular disease, are associated with systemic endothelial dysfunction and carotid intima-media thickness (IMT) remains unclear. METHODS: We evaluated participants without prevalent CVD in the Framingham Offspring Study who underwent formal audiogram testing and brachial and carotid artery ultrasounds. Audiograms were categorized as normal or as belonging to one of four abnormal patterns: cochlear-conductive, low-sloping, sensorineural, or strial. Endothelial function as measured by brachial artery flow-mediated dilation (FMDmm and FMD%). Internal and common intima-media thicknesses (icIMT and ccIMT, respectively) were compared between audiogram patterns. RESULTS: We studied 1672 participants (mean age 59 years, 57.6% women). The prevalence of each hearing pattern was as follows: 43.7% normal; 20.3% cochlear-conductive; 20.3% sensorineural; 7.7% low-sloping; and 8.0% strial. Strial pattern hearing loss was nearly twice as prevalent (p = 0.001) in those in the highest quartile of ccIMT and nearly 50% higher in those in the highest icIMT quartile (p = 0.04). There were no statistically significant differences between the prevalence of the strial pattern comparing the lowest quartiles of FMDmm and FMD% with the upper three quartiles. Age- and sex-adjusted linear regression models did not show significant associations between the vascular measures and hearing patterns. CONCLUSION: Abnormal hearing patterns were not significantly associated with impaired brachial FMD and increased carotid IMT after adjusting for age and sex effects, which may reflect age and sex-related distributional differences based on hearing loss pattern.

Cochlear Implant Performance in Candidates With Moderate Hearing Loss Qualifying in Noise.

OBJECTIVE: To determine postcochlear implantation performance for patients qualifying on preimplant testing in noise. STUDY DESIGN: Retrospective chart review of cochlear implant recipients. MAIN OUTCOME MEASURE: Performance on word and sentence testing in the implanted ear and bimodal condition were compared between pre- and postimplantation time points. RESULTS: At 2-years postimplantation, CNC testing in quiet in the implanted ear improved from an average percent correct score of 14.0 ±â€Š12.1% to 54.9 ±â€Š14.8% (n = 20, p < 0.0001, d = 3.0) for those qualifying at +8, and from 23.4 ±â€Š15.6% to 55.5 ±â€Š19.4% (n = 28, p < 0.0001, d = 1.8) for those qualifying at +5. Likewise, AzBio in quiet in the implanted ear improved from an average % correct score of 19.9 ±â€Š16.0% to 75.1 ±â€Š11.8% (n = 20, p < 0.0001, d = 4.0) for those qualifying at +8, and from 46.2 ±â€Š21.7% to 74.1 ±â€Š21.3% (n = 27, p < 0.0001, d = 1.4) for those qualifying at +5. CNC and AzBio performance in quiet in the bimodal condition also improved with those qualifying at +8 and +5 having similar average scores at 2-years post activation. For those qualifying at +8, performance improved on CNC and AzBio in the implanted ear in 95% of patients and in the bimodal condition in 89% of patients. The proportion of patients improving on both tests for those qualifying at +5 at 2 years was 85% in the implanted ear, and 72% in the bimodal condition. CONCLUSION: The majority of patients qualifying for cochlear implantation with the addition of noise showed improved speech perception in quiet. These data provide useful counseling tools for patients considering cochlear implantation who do not meet traditional eligibility requirements when tested in quiet.

Socioeconomic Determinants of Tertiary Rhinology Care Utilization.

OBJECTIVE: The objective of this study was to determine the impact of patient demographics and socioeconomic factors on the utilization of tertiary rhinology care services in an upper Midwestern academic medical center. STUDY DESIGN: Retrospective review of electronic health records. SETTING: Academic medical center. METHODS: The electronic health record of our academic center was interrogated for the demographics and diagnosis of chronic rhinosinusitis (CRS) among adult patients seen by fellowship-trained rhinologists from 2000 to 2019. Patient characteristics (age, sex, race, insurance status) and population-level data (median income and education level) were compared with utilization of tertiary rhinology services for CRS. Utilization rates were calculated for each regional zip code and correlated with census data for median income and education. The association between determinants of health and tertiary rhinology utilization was assessed by multivariate regression analyses. RESULTS: A total of 8325 patients diagnosed with CRS used tertiary rhinology services. Patients were older (median, 58.9 years) and more likely to be female (57.6%), White (85%), and privately insured (60%) when compared with patients seen across our hospital system (P < .001). Adjusted analyses showed median income, education level, and White race to be independently correlated with tertiary care utilization. Private insurance alone was not an independent contributing factor to access. CONCLUSION: Utilization of tertiary rhinology services correlated with income, race, and education level. Private insurance was not an independent factor. These results highlight social differences in determinants of access to tertiary otolaryngologic care.
