INTRODUÇÃO: A misofonia é caracterizada pela aversão a sons bem seletivos, que provocam uma forte reação emocional. Foi proposto que a misofonia, assim como o zumbido, esteja associada à hiperconectividade entre os sistemas auditivo e límbico. Indivíduos com zumbido de incômodo significativo podem apresentar comprometimento da atenção seletiva, o que ainda não foi demonstrado no caso da misofonia. OBJETIVO: caracterizar uma amostra de indivíduos com misofonia e compará-la com dois grupos controle, um com zumbido (sem misofonia) e outro assintomático (sem zumbido e sem misofonia). METODOLOGIA: Foram avaliados 40 sujeitos normo-ouvintes, sendo 10 com misofonia (grupo misofonia - GM), 10 com zumbido (sem misofonia) (grupo controle zumbido - GCZ) e 20 sem zumbido e sem misofonia (grupo controle assintomático - GCA). Foi realizada anamnese geral em todos os grupos e anamnese específica apenas para o GM. Nos três grupos, foi aplicado o Teste de Identificação de Sentenças Dicóticas em três situações. Na primeira, foi realizado o exame padrão. Em seguida, foi aplicado incluindo mensagem competitiva, uma com som de mastigação (exame mastigação), e outra com white noise (exame white noise). RESULTADOS: A amostra do GM apontou que os primeiros sintomas da misofonia foram percebidos ainda na infância ou adolescência (média 11,5 anos). O grau de incômodo variou de 6 a 10 na escala visual analógica e, dentre os 10 participantes do GM, nove (90%) responderam que a misofonia atrapalha, sempre ou às vezes, a vida social e profissional. No teste de Identificação de Sentenças Dicóticas, foi observado que no exame mastigação, as médias da porcentagem de acertos diferem entre os grupos GM e GCA (valor-p = 0,027) e entre os grupos GM e GCZ (valor-p = 0,002), sendo menor em ambos os casos no GM. Para os exames padrão e white noise, não há diferença entre as médias da porcentagem de acertos nos três grupos (valores-p >= 0,452). CONCLUSÃO: os participantes do GM apresentaram menor porcentagem de acertos no Teste de Identificação de Sentenças Dicóticas na situação de apresentação de um ruído distraidor (exame mastigação) em relação ao mesmo teste aplicado em situação padrão ou white noise, sugerindo que indivíduos com misofonia podem apresentar alteração da atenção seletiva quando expostos a sons que desencadeiam esta condição / INTRODUCTION: Misophonia is characterized by the aversion to very selective sounds, which evoke a strong emotional reaction. It has been proposed that misophonia, as well as tinnitus, is associated with hyperconnectivity between the auditory and limbic systems. Individuals with bothersome tinnitus may have selective attention impairment, but it has not been demonstrated in case of misophonia yet. OBJECTIVE: to characterize a sample of misophonic subjects and compare it to two control groups, one with tinnitus individuals (without misophonia) and the other one with asymptomatic individuals (without misophonia and without tinnitus), regarding self-perception of the condition and selective attention. METHODOLOGY: we had evaluated 40 normal hearing participants: 10 with misophonia (GM), 10 with tinnitus (without misophonia) (GCZ) and 20 without tinnitus and without misophonia (GCA). General questionnare was applied in all of three groups and specific misophonia questionnaire was applied only in GM. In order to evaluate the selective attention, it was applied the Dichotic Sentence Identification (DSI) Test in three situations: In the first one, it was applied the original test. Then, the test was applied in two other situations including two competitive sounds, one with chewing sound (chewing test), and the other one with white noise sound (white noise test). RESULTS: The GM sample indicated that the onset of misophonia occurred in childhood or adolescence (mean 11.5 years). According to the visual analog scale, the discomfort with misophonia ranged from 5 to 10, and nine (90%) participants answered that misophonia always or sometimes limits their social and professional interactions. In the chewing test, it was observed that the average of correct responses differed between GM and GCA groups (pvalue = 0.027) and between GM and GCZ groups (p-value = 0.002), in both cases it was lower in GM. In the original and white noise tests, no difference was observed between the averages of correct responses in the three groups (p-values >= 0.452). CONCLUSION: The GM participants had a lower percentage of correct responses in the chewing test, suggesting that individuals with misophonia may have selective attention impairment when they are exposed to sounds that trigger the condition

GABAB receptors play an important role in regulation of neuronal excitability and stability of neural microcircuits. It is well known that dysregulation of slow GABAergic signalisation can lead to many pathological conditions (epilepsy, anxiety etc.). Current research indicates that the imbalance in the inhibitory transfer, caused by changes in the expression of GABABR in the auditory system could play an important role in the progression of tinnitus. The goal of the present thesis was to determine the distribution of the GABAB receptor and its auxiliary subunit KCTD12 in the mouse auditory cortex and the dorsal cochlear nucleus (DCN). Furthermore, a change in GABAB receptor localization in the DCN was observed in mice exposed to an acoustic stress. The GABAB receptor was expressed across the entire auditory cortex, both on the body and on the neuronal fibres. On the contrary, KCTD12 was found only in a particular subgroup of neurons that includes VIP (vasoactive intestinal peptide) and cholecystokinin positive interneurons., GABABR and KCTD12 protein were found in all layers and in all studied cells types (fusiform, cartwheel and stellate) of the DCN. Acoustic trauma of the WT mice resulted in GABAB receptor internalization specifically in fusiform cells that are the main projection neurons of the...

Aim of the study: To evaluate the influence of high frequency hearing loss (>8000 Hz) on distortion product otoacoustic emissions registered in the frequency range from 0,5 to 8 kHz. Material and methods: 280 ears with tinnitus and normal hearing (0.25–8 kHz) divided into 3 groups depending on the degree of high frequency hearing loss: group A – hearing threshold up to 20 dB for 10, 12.5, 14 and 16 kHz (68 ears); group B – hearing threshold 25–40 dB HLfor at least one of four EHfs (93 ears); group C – hearing threshold above 40 dB HL for at least one of four EHFs (119 ears). For each group mean audiogram and DP-gram were obtained and statistical analysis was used for comparison across these groups. Results: Mean DPOAE values in group C were significantly lower in comparison with group A for the frequency range 2–8 kHz, and in comparison with group B were significantly lower for the frequency range 4–8 kHz. Conclusions: High frequency hearing loss (above 8 kHz) has a relevant influence on distortion product otoacoustic emissions registered at frequencies below 8 kHz in tinnitus patients. The greater is hearing loss above 8 kHz, the lower is DPOAE value below 8 kHz.

Background: Internet-based cognitive behavioral therapy (ICBT) for tinnitus is an evidence-based intervention. The components of ICBT for tinnitus have, however, not been dismantled and thus the effectiveness of the different therapeutic components is unknown. It is, furthermore, not known if heterogeneous tinnitus subgroups respond differently to ICBT. Aims: This dismantling study aimed to explore the contribution of applied relaxation within ICBT for reducing tinnitus distress and comorbidities associated with tinnitus. A secondary aim was to assess whether outcomes varied for three tinnitus subgroups, namely those with significant tinnitus severity, those with low tinnitus severity, and those with significant depression. Methods: A parallel randomized controlled trial design (n = 126) was used to compare audiologist-guided applied relaxation with the full ICBT intervention. Recruitment was online and via the intervention platform. Assessments were completed at four-time points including a 2-month follow-up period. The primary outcome was tinnitus severity as measured by the Tinnitus Functional Index. Secondary outcomes were included for anxiety, depression, insomnia, negative tinnitus cognitions, health-related quality of life, hearing disability, and hyperacusis. Treatment engagement variables including the number of logins, number of modules opened, and the number of messages sent. Both an intention-to-treat analysis and completer's only analysis were undertaken. Results: Engagement was low which compromised results as the full intervention was undertaken by few participants. Both the ICBT and applied relaxation resulted in large reduction of tinnitus severity (within-group effect sizes d = 0.87 and 0.68, respectively for completers only analysis), which were maintained, or further improved at follow-up. These reductions in tinnitus distress were greater for the ICBT group, with a small effect size differences (between-group d = 0.15 in favor of ICBT for completers only analysis). Tinnitus distress decreased the most at post-intervention for those with significant depression at baseline. Both ICBT and applied relaxation contributed to significant reductions on most secondary outcome measures, with no group differences, except for a greater reduction of hyperacusis in the ICBT group. Conclusion: Due to poor compliance partly attributed to the COVID-19 pandemic results were compromised. Further studies employing strategies to improve compliance and engagement are required. The intervention's effectiveness increased with initial level of tinnitus distress; those with the highest scores at intake experienced the most substantial changes on the outcome measures. This may suggest tailoring of interventions according to tinnitus severity. Larger samples are needed to confirm this.

Objective: Although tinnitus is one of the most commonly reported symptoms in the general population, patients with bothersome tinnitus are challenged by issues related to accessibility of care and intervention options that lack strong evidence to support their use. Therefore, creative ways of delivering evidence-based interventions are necessary. Internet-based cognitive behavioral therapy (ICBT) demonstrates potential as a means of delivering this support but is not currently available in the United States. This article discusses the adaptation of an ICBT intervention, originally used in Sweden, Germany, and the United Kingdom, for delivery in the United States. The aim of this study was to (a) modify the web platform's features to suit a U.S. population, (b) adapt its functionality to comply with regulatory aspects, and (c) evaluate the credibility and acceptability of the ICBT intervention from the perspective of health care professionals and patients with bothersome tinnitus. Materials/Method:Initially, the iTerapi ePlatform developed in Sweden was adopted for use in the United States. Functional adaptations followed to ensure that the platform's functional and security features complied with both institutional and governmental regulations and that it was suitable for a U.S. population. Following these adaptations, credibility and acceptance of the materials were evaluated by both health care professionals (n = 11) and patients with bothersome tinnitus (n = 8). Results:Software safety and compliance regulatory assessments were met. Health care professionals and patients reported favorable acceptance and satisfaction ratings regarding the content, suitability, presentation, usability, and exercises provided in the ICBT platform. Modifications to the features and functionality of the platform were made according to user feedback. Conclusions:Ensuring that the ePlatform employed the appropriate features and functionalities for the intended population was essential to developing the Internet-based interventions. The favorable user evaluations indicated that the intervention materials were appropriate for the tinnitus population in the United States.

An Internet-based tinnitus intervention for use in the USA can address barriers that weaken the provision of tinnitus-related services. Although such interventions exist, their suitability for this population was questioned. The aim of this study was to adapt an Internet-based cognitive behavioural therapy intervention (ICBT) for tinnitus to ensure its utility for a US population. The study objectives were to ensure the program’s accessibility in terms of readability, language, and cultural appropriateness. Methods: The intervention materials were redesigned and simplified to support use by a novel patient group. Readability Studio was used to evaluate reading levels using six different formula. Cultural and linguistic adaptions were identified by clinicians in the USA. Accessibility was further enhanced as the intervention materials were translated into Spanish. Results: Accessibility measures ensured all chapters had readability levels of between Grades 5-6. Cultural and linguistic adaptations were made in terms of content, vocabulary, and spelling. To improve patient engagement, adaptions were made to the interactive elements, goal setting and worksheets. Conclusion: Internet intervention materials were revised to adhere to best practice guidelines. Further studies should determine whether these changes improved self-efficacy, engagement, and aided motivation to complete the intervention.

Objectives: Although tinnitus is one of the most commonly-reported symptoms in the general population, patients with bothersome tinnitus are challenged by issues related accessibility of care, and intervention options that lack strong evidence to support their use. Therefore, creative ways of delivering evidence- based interventions are necessary. This presentation focuses on the adaptation of an Internet-based Cognitive Behavioral Therapy (ICBT) intervention, originally used in Sweden and in the UK, for individuals with tinnitus in the United States. Elements of the ICBT program requiring consideration included (a) adaptations to the platform’s features and functionalities, (b) translation into Spanish to extend the reach of the program (c) user acceptability and satisfaction of the program, (d) outcomes from a pilot trial from which it was hypothesized that patients would demonstrate a reduction in tinnitus distress and associated difficulties as measures using standardized self-reported outcome measures, and (e) discussion of the relative merits and appropriateness of the intervention. Design: The iTerapi platform developed in Sweden was adopted for use in the US. The platform required functional and security features modifications to confirm its compliance with both institutional and governmental regulations, and to ensure it was suitable for the US population. Acceptability and suitability of the materials were evaluated by both hearing healthcare professionals (n=11) andindividuals with tinnitus (n=8). A pilot study followed as adults with bothersome tinnitus completed the 8-week program (n=30). Results: Cultural adaptations included word substitutions, adapting counseling examples for a US population, and modifying the spelling of certain words. The materials were then translated into Spanish and cross-checked. Professional review ensured the suitability of the chapters. Literacy level analysis confirmed all chapters were within the guidelines to be below the 6th grade level for readability. Healthcare professionals and individuals with tinnitus reported favorable acceptance and satisfaction ratings regarding the content, suitability, presentation, usability and exercises provided in the ICBT platform. Preliminary analyses of pilot data indicated a reduction in tinnitus distress and associated difficulties (i.e., anxiety, depression, insomnia) and an improvement in quality of life. Conclusions: Ensuring that the ePlatform offers the appropriate features and functionalities for the intended population is an essential part of developing Internet-based intervention. The user evaluations and pilot trial outcomes indicated that clinical trials can be performed to assess the effectiveness of ICBT for tinnitus in the US.

Purpose: An Internet-based tinnitus intervention for use in the United States could improve the provision of tinnitus-related services. Although clinical trials of such interventions were completed in Europe, the United Kingdom, and Australia, their suitability for adults with tinnitus in the United States is yet to be established. The aim of this study was to improve the cultural and linguistic suitability, and lower the readability level, of an existing program for tinnitus to ensure its suitability for U.S. English- and Spanish-speaking populations. Method: Guidelines for adaptation were followed and involved four phases: (a) cultural adaptations, as interventions targeted at specific cultures have been shown to improve outcomes; (b) creating Spanish materials to improve access of the materials to the large Spanish-speaking population in the United States; (c) professional review of the materials for acceptability as an intervention tool for a U.S. population; and (d) literacy-level adjustments to make the content accessible to those with lower levels of health literacy skills. Results: Cultural adaptations were made by using word substitutions, changing examples, and modifying the spelling of certain words. The materials were then translated into Spanish and cross-checked. Professional review ensured suitability of the chapters. Literacy-level adjustments ensured all chapters were within the guidelines for readability grade levels below the sixth-grade level. Conclusions: The previously developed tinnitus materials were revised to adhere to best practice guidelines and ensure cultural suitability for adults with tinnitus in the United States. As it is also available in Spanish, members of the large Hispanic community also have access to the intervention in their first language. Further studies should determine whether these changes improve patients' self-efficacy, engagement, and motivation to complete the intervention.

Objective: The objective of this study was to improve the range of standardised tinnitus Spanish Patient-Reported Outcome Measures (PROMS) available by translating and ensuring cross-cultural adaptation of three English PROMs to Spanish. Design: The Tinnitus and Hearing Survey, Tinnitus Cognition Questionnaire, and Tinnitus Qualities Questionnaire were translated to Spanish using recently established good practice guidelines. Study sample: The translation process addressed 22 items included in six main steps specified in the guidelines. The translated PROMs were field tested on a sample of tinnitus patients who were recruited through convenience sampling using cognitive debriefing (n = 5) and pilot testing (n = 10) methods. Results: The translation process employed the required steps and provided specific details about the process and procedures. In addition, practical issues encountered while translating and adapting the questionnaires that may influence future translations were revealed. Conclusions: This is the first account of translating and adapting PROMs from one language to another using the good practice guidelines specific to hearing-related questionnaires. Following the rigorous procedures should ensure that the translated PROMs have linguistic and cultural equivalence to the original versions, although psychometric evaluation would remain necessary to confirm the functional equivalence.
