RESUMO
PURPOSE: To propose an instrument for assessing speech recognition in the presence of competing noise. To define its application strategy for use in clinical practice. To obtain evidence of criterion validity and present reference values. METHODS: The study was conducted in three stages: Organization of the material comprising the Word-with-Noise Test (Stage 1); Definition of the instrument's application strategy (Stage 2); Investigation of criterion validity and definition of reference values for the test (Stage 3) through the evaluation of 50 normal-hearing adult subjects and 12 subjects with hearing loss. RESULTS: The Word-with-Noise Test consists of lists of monosyllabic and disyllabic words and speech spectrum noise (Stage 1). The application strategy for the test was defined as the determination of the Speech Recognition Threshold with a fixed noise level at 55 dBHL (Stage 2). Regarding criterion validity, the instrument demonstrated adequate ability to distinguish between normal-hearing subjects and subjects with hearing loss (Stage 3). Reference values for the test were established as cut-off points expressed in terms of signal-to-noise ratio: 1.47 dB for the monosyllabic stimulus and -2.02 dB for the disyllabic stimulus. Conclusion: The Word-with-Noise Test proved to be quick to administer and interpret, making it a useful tool in audiological clinical practice. Furthermore, it showed satisfactory evidence of criterion validity, with established reference values.

PURPOSE: To analyze the effects of auditory stimulation on heart rate variability (HRV) indices in healthy individuals with normal hearing and with hearing loss, regardless of type and/or grade, by means of a systematic review. RESEARCH STRATEGIES: This is a systematic review with a meta-analysis that addresses the following question: in healthy individuals with normal hearing and/or with hearing loss, what are the effects of auditory stimulation on HRV indices in comparison to silence? We consulted the Cochrane Library, Embase, LILACS, PubMed, Web of Science, and Scopus databases and the gray literature (Google Scholar, OpenGrey, and ProQuest). SELECTION CRITERIA: There were no restrictions as to period or language of publication. DATA ANALYSIS: We identified 451 records, an additional 261 in the gray literature, and five studies in a search through the references, resulting in a total of 717 records, with 171 duplicate records. After screening the titles and abstracts of 546 studies, we excluded 490 and considered 56 studies in full to assess their eligibility. RESULTS: Nine of these studies were included in the systematic review, eight of which were suitable for the meta-analysis. CONCLUSION: It is suggested that auditory stimulation may influence the RMSSD, pNN50, SDNN, RRTri and SD2 indices of HRV in healthy adults with normal hearing.

OBJECTIVES: Research focusing on changes in the clinical practice of audiological diagnosis has become increasingly necessary, particularly in pediatric audiology. The pursuit of accurate and reliable examinations has intensified given the importance of early detection and intervention in cases of childhood hearing loss. Thus, this study aims to investigate the correlation between electrophysiological auditory thresholds, as obtained through frequency-specific auditory brainstem responses with two distinct chirp stimuli (narrow-band CE-Chirp Level Specific and narrow-band iChirp), in children with hearing impairments. In addition, this research set out to correlate these thresholds with behavioral responses while simultaneously comparing the examination durations relative to the type of stimuli and the degree of hearing loss. DESIGN: A cohort of 20 children (aged 6 months to 12 years) with varying degrees of hearing impairment (ranging from mild to profound) were recruited. The participants underwent bilateral measurement of their electrophysiological thresholds via auditory brainstem responses across different frequencies (500, 1000, 2000, and 4000 Hz), and the timeframe for determining these thresholds was carefully recorded. Subsequently, behavioral thresholds were ascertained using pure-tone audiometry or visual reinforcement audiometry based on the child's age. The data collected was subsequently analyzed using Pearson and Spearman correlation coefficients. To compare examination times, the Student t test and the Kruskal-Wallis test were used. RESULTS: There was a pronounced correlation between the thresholds obtained through both narrow-band chirp stimuli. Moreover, a substantial correlation was found between electrophysiological and behavioral thresholds at 1000, 2000, and 4000 Hz, especially when compared with pure-tone audiometry. The mean differences between the electrophysiological and behavioral thresholds were below 6 dB nHL, and the exam duration was relatively consistent across both devices, averaging 47.63 (±19.41) min for the narrow-band CE-Chirp Level Specific and 52.42 (±26) min for the narrow-band iChirp. Notably, variations in exam duration did not relate to varying degrees of hearing loss when using the narrow-band CE-Chirp Level Specific. Nevertheless, the narrow-band iChirp indicated significantly shorter durations in instances of profound degree measurements, demonstrating a statistically significant difference. CONCLUSIONS: The narrow-band CE-Chirp Level Specific and narrow-band iChirp stimuli provided similar estimates of electrophysiological auditory thresholds in children with hearing impairments, giving accurate estimations of behavioral thresholds. The time it took to complete the assessment is comparable between both stimuli. For the narrow-band iChirp, the degree of hearing loss was shown to impact the testing time, and children with profound hearing loss underwent faster exams. Ultimately, this study exhibits significant clinical implications as it reveals that the narrow-band CE-Chirp Level Specific and narrow-band iChirp stimuli could be remarkably promising for clinically exploring electrophysiological thresholds in children with hearing impairments.

Hearing loss is a heterogeneous disorder. Identification of causative mutations is demanding due to genetic heterogeneity. In this study, we investigated the genetic cause of sensorineural hearing loss in patients with severe/profound deafness. After the exclusion of GJB2-GJB6 mutations, we performed whole exome sequencing in 32 unrelated Argentinean families. Mutations were detected in 16 known deafness genes in 20 patients: ACTG1, ADGRV1 (GPR98), CDH23, COL4A3, COL4A5, DFNA5 (GSDDE), EYA4, LARS2, LOXHD1, MITF, MYO6, MYO7A, TECTA, TMPRSS3, USH2A and WSF1. Notably, 11 variants affecting 9 different non-GJB2 genes resulted novel: c.12829C > T, p.(Arg4277*) in ADGRV1; c.337del, p.(Asp109*) and c.3352del, p.(Gly1118Alafs*7) in CDH23; c.3500G > A, p.(Gly1167Glu) in COL4A3; c.1183C > T, p.(Pro395Ser) and c.1759C > T, p.(Pro587Ser) in COL4A5; c.580 + 2 T > C in EYA4; c.1481dup, p.(Leu495Profs*31) in LARS2; c.1939 T > C, p.(Phe647Leu), in MYO6; c.733C > T, p.(Gln245*) in MYO7A and c.242C > G, p.(Ser81*) in TMPRSS3 genes. To predict the effect of these variants, novel protein modeling and protein stability analysis were employed. These results highlight the value of whole exome sequencing to identify candidate variants, as well as bioinformatic strategies to infer their pathogenicity.

RESUMO Objetivo Verificar a correlação das diferentes médias tonais (tritonal, quadritonal e octonal) com o Índice Percentual de Reconhecimento de Fala e com a desvantagem auditiva. Métodos Participaram do estudo 56 sujeitos, distribuídos em dois grupos, com configuração audiométrica descendente: Grupo 1 (G1) - 28 sujeitos com média tritonal igual ou inferior a 25 dBNA e Grupo 2 (G2) - 28 sujeitos com média tritonal pior que 25 dBNA (G2), sendo pareados quanto ao gênero e idade (p= 0,544). Todos foram submetidos à audiometria tonal liminar, Índice Percentual de Reconhecimento de Fala (IPRF) com lista monossilábica de palavras gravadas, medidas de imitância acústica e ao questionário Hearing Handicap Inventory for Adults. A análise de correlação foi realizada entre as médias de três frequências (M3), de quatro frequências (M4) e de oito frequências (M8) com o IPRF e com a desvantagem auditiva, utilizando o teste de correlação de Spearman, sendo o nível de significância considerado <0,05 (5%). Resultados Evidenciou-se correlação estatisticamente significativa do IPRF com a M8, para o G1, e do IPRF com M4 e M8, para o G2. Observou-se tendência à significância, tanto para o G1, como para o G2, em relação à M8, quando correlacionada com a desvantagem auditiva, demonstrando que analisar as oito frequências do audiograma (frequências mais agudas que 4000 Hz) parece possibilitar maior compreensão em relação à desvantagem auditiva do paciente. Conclusão Houve correlação estatisticamente significativa do IPRF com a M8, nos dois grupos, denotando uma redução no desempenho do IPRF, com o aumento da média, considerando as oito frequências. A M8 refletiu melhor a desvantagem auditiva causada pela perda auditiva, no G1.
ABSTRACT Purpose To verify the correlation of different tonal means (tritonal, quadritonal and octanol) with the Percentage Index of Speech Recognition and with hearing disadvantage. Methods 56 subjects participated in the study, distributed into two groups, with descendant audiometric configuration: Subjects with tritonal average equal to or less than 25 dB HL(G1) and subjects with a tritone average worse than 25 dB HL(G2), being matched for sex and age (p=0.544). All were safe by Threshold Tone Audiometry, Speech Recognition Percentage Index (IPRF) with a list of keywords, Acoustic I Measures and the Elearing Handicap Inventory for Adults. The correlation analysis was performed between the averages, of three frequencies (M3), of four frequencies (M4) and of eight frequencies (M8) with the IPRF and with auditory disadvantage, using the Spearman correlation test, the significance level being considered <0.05 (5%). Results There was a statistically significant correlation of the IPRF with M8 , for G1, and the IPRF with M4 and M8, for G2. There was a tendency towards significance, both for G1 and G2, in relation to M8 when correlated with hearing impairment, demonstrating that analyzing the eight frequencies of the audiogram (frequencies higher than 4000 Hz) seems to allow a greater understanding of the patient's hearing handicap. Conclusion There was a statistically significant correlation between the IPRF and M8, in both groups, denoting a reduction in the performance of the IPRF, with an increase in the mean, considering the eight frequencies. M8 better reflected the hearing disadvantage caused by the hearing loss in G1.

Congenital hypothyroidism (CH) is an endocrine disease commonly found in newborns and is related to the absence or reduction of thyroid hormones (THs), which are essential for development since intrauterine life. Children with CH can develop hearing problems as THs are crucial for the auditory pathway's development and maturation. Sensory deprivations, especially in hearing disorders at early ages of development, can impair language skills, literacy, and behavioral, cognitive, social, and psychosocial development. In this review we describe clinical and molecular aspects linking CH and hearing loss.

El Discurso Narrativo (DN) es una unidad lingüística compleja utilizada en ciertos contextos y que refleja la organización del pensamiento. La evidencia científica muestra que la población sorda, usuaria de ayudas auditivas, presenta dificultades en los diferentes niveles del lenguaje, tanto expresivos como comprensivos, incluida la habilidad para narrar. Además, existe evidencia de que la intervención terapéutica ayudaría a mejorar su rendimiento. Sin embargo, los datos disponibles sobre las características y abordaje del DN en esta población son escasos. El objetivo del estudio es evaluar un programa piloto para trabajar habilidades narrativas en niños chilenos usuarios de ayudas auditivas. Se estudiaron 22 niños con un promedio de edad de 6,5 años, adaptados con audífonos y/o implante coclear. Se aplicó a este grupo de niños una evaluación inicial del DN utilizando el instrumento Evaluación del Discurso Narrativo (EDNA), obteniéndose la Etapa y Desempeño narrativo de cada niño. Luego, se creó y aplicó individualmente un programa de estimulación del discurso narrativo de 12 sesiones una vez por semana. Finalmente, se repitió la evaluación al final del programa. Se encontraron diferencias significativas entre los resultados obtenidos previo y posterior a la implementación del programa de estimulación. En relación con la Etapa del DN, antes de la intervención el 45,5% de los niños no estructuraba, lo cual se redujo a un 9.1% en la evaluación final. En cuanto al Desempeño, previo a la intervención el 72,7% de los niños presentaba un "déficit narrativo", lo cual se redujo a un 18,2% posterior a la aplicación del programa.
Narrative discourse is considered a linguistic unit that is used in a specific communicative context, being an indicator of thinking organization. Previous evidence shows how hearing aid users, have difficulties with different language skills, both expressive and comprehensive, including the ability to narrate. Additionally, there is evidence showing how therapeutic intervention would help to improve their narrative performance. However, the information available about the discursive skilland the effect ofstimulation programs on it in hearing impaired children is scarce. Accordingly, the present study aims to explore narrative performance in hearing impaired children users of hearing aids/cochlear implants, before and after a narrative speech stimulation program. Twenty-two children diagnosed with bilateral hearing loss users of hearing aids/cochlear implants with a mean age of 6.5 years were included. An initial assessment of the narrative skills was performed using Narrative Discourse Assessment (EDNA), which provided a narrative Stage and a Total score. A twelve-session stimulation program was developed and individually administered to children once a week. Finally, an assessment was performed after the program ended. In the initial assessment, 45.5% of children did not have a structured narrative speech, a percentage that was reduced to a 9.1% in the final evaluation. Statistically significant differences were observed on the EDNA scores when comparing initial and final assessments. The results obtained in the present investigation show how children who use hearing aids/cochlear implants improved significantly their narrative abilities after participating in a pilot narrative speech stimulation program.

Abstract Introduction Tinnitus is present in a large part of chronic health complaints, and it is considered a public health problem injurious to the individual's quality of life. Considering the increase of the world population associated with an increase of life expectancy, tinnitus remains a cause for medical concern, since during aging the occurrence of auditory impairments due to the deterioration of the peripheral auditory structures and central impairs the quality of life. Objective The aim of the present study was to analyze the applicability of real ear measurements for audiological intervention of tinnitus through specific evaluation, selection, verification and validation of the hearing aids combined with the sound generator. Methods Forty individuals of both genders with hearing loss and tinnitus complaints were deemed eligible to compose the sample. They were enrolled according to clinical symptoms and submitted to the following procedures: anamnesis and previous complaint history, high frequency audiometry, immittanciometry and acuphenometry with the research of psychoacoustic thresholds of pitch, loudness and minimum masking threshold, sound generator, in addition to the application of the Tinnitus Handicap Inventory and Visual Analog Scale tools. The entire sample was adapted with Siemens hearing aids and a sound generator, participated in a counseling session with support of digital material and evaluated in two situations: Initial Assessment (before the hearing aids and sound generator adaptation) and Final Assessment (6 months, after adaptation). The statistical analyzes were descriptive and inferential, adopted a significance level of 5% and the T-Paired Test and the Spearman Correlation test were performed. Results The results showed that there was a benefit with the use of hearing aids combined with a sound generator from the statistically significant values and strong correlations between the sound generator verification data regarding acuphenometry and the nuisance/severity questionnaires. Regarding the verification of the sound generator, it is important to highlight that the entire sample selected the effective acoustic stimulation based on the comfort levels, which was proved in the present study to be a sufficient intensity for positive prognosis, whereas the users' noises were found below the psychoacoustic thresholds of acuphenometry. Conclusion The present study concluded that the audiological intervention with any level of sound stimulus is enough to obtain a positive prognosis in the medium term. Data that specifies that the verification of sound generator was effective at the real ear measurements are important in the evaluation and intervention of the complaint. In addition, it points out that the greater the tinnitus perception, the greater its severity, and the greater the nuisance, the higher the psychoacoustics thresholds of frequency and the minimum threshold of masking.
Resumo Introdução O zumbido está presente em grande parte das queixas crônicas de saúde, é considerado um problema de saúde pública, prejudicial à qualidade de vida do indivíduo. Considerando o aumento da população mundial associado ao aumento da expectativa de vida, a tendência é que o zumbido permaneça como um motivo de preocupação, uma vez que com a idade a ocorrência de prejuízos auditivos decorrentes da deterioração das estruturas auditivas periféricas e centrais ocasiona grande impacto negativo na qualidade de vida. Objetivo Analisar a aplicabilidade das medidas da orelha real para a intervenção audiológica do zumbido através de avaliação específica, seleção, verificação e validação do aparelho de amplificação sonora individual combinada ao gerador de som. Método Quarenta indivíduos de ambos os sexos com perda auditiva e queixa de zumbido foram considerados elegíveis para compor a amostra. Eles foram atendidos conforme a demanda clínica e submetidos aos seguintes procedimentos: anamnese e história pregressa da queixa, audiometria de alta frequência, imitanciometria e acufenometria com pesquisa dos limiares psicoacústicos de pitch, loudness e limiar mínimo de mascaramento, gerador de som, além da aplicação das ferramentas tinnitus handicap inventory e escala visual analógica. Toda a amostra recebeu aparelho de amplificação sonora individual e gerador de som, ambos da marca Siemens, participaram de uma sessão de aconselhamento com apoio de material digital e foram avaliados em duas situações: Avaliação inicial (antes da adaptação dos aparelhos de amplificação sonora individual e gerador de som) e Avaliação final (6 meses após a adaptação). As análises estatísticas foram descritivas e inferenciais, adotou-se um nível de significância de 5% com a realização do teste t pareado e o teste de correlação de Spearman. Resultados Os resultados mostraram que houve benefício com o uso de aparelho de amplificação sonora individual combinado ao gerador de som com base nos valores estatisticamente significantes e fortes correlações entre os dados da verificação do gerador de som em relação à acufenometria e os questionários de incômodo/gravidade. Em relação à verificação do gerador de som, é importante destacar que toda a amostra selecionou a estimulação acústica efetiva baseada nos níveis de conforto e no presente estudo demonstraram ser de intensidade suficiente para o prognóstico positivo, enquanto que os ruídos dos usuários estavam abaixo dos limiares psicoacústicos da acufenometria. Conclusão A intervenção audiológica com qualquer nível de estímulo sonoro é suficiente para obter um prognóstico positivo em médio prazo. Os dados que demonstram que a verificação do gerador de som foi efetiva nas medidas da orelha real são importantes na avaliação e intervenção da queixa. Além disso, mostram que quanto maior a percepção do zumbido, maior a sua gravidade; e quanto maior o incômodo, maiores os limiares de frequência psicoacústica e o limiar mínimo de mascaramento.

Objective: To develop a web-based application for a colour pattern memory recognition task as the secondary task of a dual-task paradigm and to compare the listening effort required by adolescents with hearing loss (HL) under two conditions (HA and HA + FM system), to adolescents with normal hearing (NH).Design: Cohort study. The participants underwent a dual-task paradigm, including the Hearing in Noise Test as the primary task and a colour memory task as the secondary task. A platform, PALETA, was developed to assess the secondary task.Study sample: In total, 31 adolescents were enrolled, of which 13 adolescents had HL and 18 adolescents had NH (mean age, 14 years).Results: Adolescents with NH scored significantly better on the secondary task compared to participants with HL using a HA. However, on analysing response time, no significant differences were observed among the groups.Conclusion: PALETA is proposed as a test procedure for the secondary task. The results revealed that the use of an FM system reduces the listening effort that adolescents with HL deploy to recognise speech in noise, and that listening effort data by number of correct responses is a way of investigating the benefits of using FM system.
