The effects of auditory stimulation on heart rate variability in healthy individuals with normal hearing and with hearing loss: a systematic review and meta-analysis.

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.

How should hyperbilirubinemia be considered in the definition of the hearing screening protocol for neonates at risk? / Como a hiperbilirrubinemia deve ser considerada na definição do protocolo da triagem auditiva para neonatos de risco?

PURPOSE: To analyze hyperbilirubinemia as an indicator for the definition of risk protocol in newborn hearing screening (NHS) and in auditory monitoring in full-term and preterm neonates. METHODS: This is an observational, cross-sectional and retrospective study. A total of 554 children born in a public maternity hospital were included and divided into two groups: (G1) with 373 full-terms neonates; (G2) with 181 preterm neonates. Data were collected from the participant's medical records to obtain information regarding the result of the NHS, performed by recording the automated auditory brainstem response (AABR), birth conditions, clinical characteristics, interventions performed, and results of the first test of total bilirubin (TB) and indirect bilirubin (IB) as well as the peak of TB and IB. A descriptive statistical analysis of the results was performed, and the level of significance adopted was 5%. RESULTS: On the NHS test, quotes of retest referral rates were smaller in G1 when compared to G2. There was no significant difference between the groups regarding type of delivery, gender, presence of Rh and ABO incompatibility, G6PD enzyme deficiency, and performance of phototherapy. TB and IB levels at the first exam and at peak time did not differ between neonates with "pass" and "fail" results on the NHS test in both groups. CONCLUSION: Bilirubin levels in the neonatal period below the recommended values for indication of exchange transfusion are not directly related to the "fail" result on the NHS tests in term and preterm neonates.

OBJETIVO: Analisar a hiperbilirrubinemia como indicador para a realização do protocolo de risco na triagem auditiva neonatal (TAN) e no monitoramento auditivo em neonatos a termo e prematuros. MÉTODO: Trata-se de um estudo observacional, transversal e retrospectivo. Foram incluídas 554 crianças nascidas em uma maternidade pública, subdivididas em dois grupos: (G1) com 373 recém-nascidos a termo; (G2) com 181 neonatos prematuros. Os dados foram coletados nos prontuários dos participantes, a fim de se obter informações referentes ao resultado da TAN realizada por meio do registro do Potencial Evocado Auditivo de Tronco Encefálico, às condições de nascimento, características clínicas, intervenções realizadas, resultados do primeiro exame de bilirrubina total (BT) e bilirrubina indireta (BI) e do pico de BT e BI. Realizou-se análise estatística descritiva e inferencial dos dados, com adoção do nível de significância de 5%. RESULTADOS: No teste da TAN, foram observadas taxas de encaminhamento para reteste inferiores no G1 em relação ao G2. Não houve diferença entre os grupos quanto à ocorrência do tipo de parto, sexo, presença de incompatibilidade sanguínea Rh e ABO, deficiência de enzima G6PD e realização de fototerapia. Em relação aos níveis de BT e BI no primeiro exame e no momento do pico, não houve diferenças entre os neonatos com resultado "passa" e "falha" na TAN-teste nos dois grupos. CONCLUSÃO: Os níveis de bilirrubina no período neonatal abaixo dos valores recomendados para indicação de exsanguineotransfusão não estão diretamente relacionados ao resultado "falha" na TAN em neonatos a termo e prematuros.

From research to clinical practice: An analysis of 226 Hz-probe tone tympanometry to identify otitis media with effusion in children.

OBJECTIVES: (1) To calculate the sensitivity and specificity of tympanometry with a 226 Hz probe to identify middle ear condition in children; (2) To propose the intersection range of static compliance and tympanometric peak pressure values obtained in ears with and without middle ear effusion. METHODS: 224 children's ears without middle ear alteration, with a mean age of 1 year and 4 months (GI), and 56 children's ears with middle ear effusion (GII), with a mean age of two years, were analyzed. For analysis, the static compliance and tympanometric peak pressure values obtained in the tympanometry with a 226 Hz probe were considered. RESULTS: In the group with no alteration, the Mann Whitney Test showed no significant difference between the sexes for the static compliance (p = 0.085) and tympanometric peak pressure (p = 0.782). No difference was seen, either, for compliance (p = 0.079) and pressure (p = 0.678) values, according to age. When applying the optimal criterion of the ROC curve, the cutoff value obtained was ≤0.26 ml for static compliance (sensitivity= 83.9 %; specificity= 86.6 %) and ≤-56 daPa for peak pressure (sensitivity= 82.1 %; specificity= 84.8 %). When comparing the values obtained for the two groups, it is noted that the data overlap, that is, they create an inconclusive intersection range between the normal middle ear and the altered one. CONCLUSION: The tympanometry cut-off with greater sensitivity and specificity was, respectively, 83.9 and 86.6 % for static compliance and 82.1 and 84.8 % for tympanometric peak pressure. The ranges from 0.16 to 0.43 ml for static compliance and from -109 to 25 daPa for tympanometric peak pressure do not allow defining the presence or absence of alteration in the middle ear, in children aged 6 to 36 months.

PURPOSE: To evaluate the usability and satisfaction of users with the interface of the 'Agente Escuta' application, in addition to identifying problems and possibilities for improvement. METHODS: Descriptive exploratory translational study, characterized by a usability test with a quantitative and qualitative approach, subdivided into three stages: (I) prior evaluation of usability by 10 judges, including students, primary care professionals, professors and researchers in Information Technology and Speech Therapy; (II) evaluation of the application by the target audience, that is, community health agents from six municipalities in Rio Grande do Norte; (III) evaluation of the satisfaction of the agents who used the application in their work routine. The System Usability Scale and the Net Promoter Score were used, in addition to a qualitative evaluation of the opinions. RESULTS: Usability was rated as excellent by judges, regardless of category. In the evaluation by community health agents, usability was considered good and there was no effect of the city of origin. It was found that the perception of the judges and the target audience were different, with a lower score for the participants in the second stage. However, most would give positive publicity to the product. The heuristic with the highest score was ease of memorization and participants in the third stage were interested in continuing to use the tool in practice, even after the end of the study. CONCLUSION: The Agente Escuta prototype showed good usability and satisfaction and aspects that could be improved in future solutions were identified.

Wideband absorbance for the assessment of pressure equalizing tubes patency in children.

OBJECTIVES: To analyze the feasibility of using wideband absorbance to verify the patency of pressure equalizing tubes (PETs) in clinical practice and to present the response pattern of this measure for ears with patent PET. METHODS: This observational case-control type study evaluated 48 ears of 30 children with severe or profound hearing loss, aged 10-44 months, of both sexes. The subjects were subdivided into two groups: 24 ears with Sheppard type PET (experimental group - EG) and 24 ears with normal middle ear (control group - CG), paired with the EG, according to age, sex, and ear evaluated. To obtain the wideband absorbance, a Middle-Ear Power Analyzer, version 5.0 (Mimosa Acoustics), was used, and absorbance values for pure tone and chirp stimuli were analyzed. RESULTS: There was no influence of ear (right or left) on the measurements obtained. The EG showed higher absorbance values at low frequencies. Although the two stimuli made it possible to identify the difference in acoustic transfer function between the groups studied, compared to pure tone, the chirp stimulus allowed identification of differences in a higher number of frequencies. CONCLUSIONS: Ears with a patent PET present an acoustic transfer pattern that differs from that obtained for normal middle ears, with a higher absorbance at low frequencies. Both pure tone and chirp stimuli can be used to identify such differences, nevertheless, the use of chirp stimulus is recommended, since it allows differentiation over a wider frequency range.

Percepção dos pais sobre hipersensibilidade auditiva de crianças com sinais clínicos de risco para o Transtorno do Espectro do Autismo / Parents' perception of auditory hypersensitivity in children with clinical signs of risk for Autism Spectrum Disorder

Resumo Objetivo Averiguar a ocorrência e o tipo de hipersensibilidade auditiva em crianças com sinais clínicos de Transtorno do Espectro do Autismo por meio do relato dos pais no contexto da pandemia da COVID-19. Método Trata-se de um estudo transversal e descritivo, composto por pais de 11 crianças com sinais clínicos de risco para Transtorno do Espectro do Autismo. As crianças eram de ambos os sexos, com média de 44,8 meses de idade. Os pais responderam, por meio de contato telefônico, a um questionário, previamente validado, sobre comportamentos de hipersensibilidade auditiva de seus filhos. Foi considerado como sinalizador de hipersensibilidade a pontuação igual ou superior a oito pontos no escore geral. Resultados 63,6% das crianças apresentaram resultado indicativo de hipersensibilidade e 54,5% obtiveram pontuação máxima nas questões relacionadas à irritabilidade a sons específicos. Os sons citados como geradores de irritabilidade foram: palmas, fogos, gritos, ferramentas de construção, canto e toque de celular. Conclusão Constatou-se ocorrência de hipersensibilidade auditiva, especialmente relacionada à irritabilidade, o que sugere relação com o sistema límbico e, portanto, pode remeter à misofonia. Assim, torna-se importante a equipe multidisciplinar atentar-se à ocorrência e a características de hipersensibilidade dessa população, a fim de maximizar condições favoráveis à reabilitação.

Abstract Objective To investigate the occurrence and type of auditory hypersensitivity in children with clinical signs of Autism Spectrum Disorder through parents' reports in the context of the COVID-19 pandemic. Method This is a cross-sectional and descriptive study, composed of parents of 11 children with clinical signs of risk for Autism Spectrum Disorder. The children were of both sexes, with a mean age of 44.8 months. Parents answered a previously validated questionnaire about their children's auditory hypersensitivity behaviors by telephone. A score equal to or greater than eight points in the general score was considered as a sign of hypersensitivity. Results 63.6% of the children presented results indicative of hypersensitivity and 54.5% obtained maximum scores on questions related to irritability to specific sounds. The sounds cited as generating irritability were: clapping, fireworks, shouting, construction tools, singing and cell phone ringtones. Conclusion Auditory hypersensitivity was observed, especially related to irritability, which suggests a relationship with the limbic system and, therefore, may refer to misophonia. Thus, it is important for the multidisciplinary team to pay attention to the occurrence and characteristics of hypersensitivity in this population, in order to maximize favorable conditions for rehabilitation.

Virtual audiometer: technology integrated to teaching. / Audiômetro virtual: tecnologia integrada ao ensino.

PURPOSE: To elaborate a virtual tool, with didactic purposes, that allows the integration of technology to the teaching of Pure Tone Audiometry (PTA) and speech audiometry. METHODS: The Interacoustics AD229b audiometer was used as a physical model to achieve the virtual tool. The Visual Basic 6 programming language was used, so that the colors, characters, and functions were similar to the real audiometer. In addition, the possibility of simulating the patient's response was added, as well as of recording the hearing thresholds in a virtual audiogram. For speech audiometry, the possibility of adjusting the VU meter and recording the number of correct and incorrect answers were implemented. RESULTS: The developed tool was able to reproduce frequencies from 125 Hz to 8000 Hz, in intensities ranging from -10 to 110 dB, being possible to use different stimulus, as well as clinical masking by air and bone conduction. The microphone button can be used to facilitate the teaching of speech audiometry. CONCLUSION: The virtual version of the audiometer is similar to the model equipment, making the integration of technology into teaching feasible, with exemplify the PTA and speech audiometry.

Além disso, acrescentou-se a possibilidade de simular a resposta do paciente, como também de registrar os limiares auditivos em um audiograma virtualizado. Para a logoaudiometria, implementou-se a possibilidade de ajuste do "VU meter" e o registro da quantidade de acertos e erros no exame. RESULTADOS: A ferramenta desenvolvida mostrou-se capaz de reproduzir as frequências de 125 a 8000 Hz, em intensidades que variam de -10 a 110 dB, sendo possível empregar diferentes formas de apresentação do estímulo, assim como o mascaramento clínico por condução aérea e óssea. A ativação da função "microfone" pode ser aplicada para facilitar o ensino da logoaudiometria. CONCLUSÃO: A versão virtualizada do audiômetro mostrou-se semelhante ao equipamento modelo, tornando factível a integração da tecnologia ao ensino, com exemplificação da ATL e da logoaudiometria.

Contralateral Masking in the Measurement of Auditory Brainstem Responses with Air-Conducted Tone Burst Stimuli in Individuals with Unilateral Hearing Loss.

BACKGROUND: Contralateral noise masking is an important aspect of auditory brainstem response (ABR) measurements. PURPOSE: The primary aim of this study is to determine how contralateral white noise (WN) masking influences the amplitude and the latency of V wave generated during ABR measurements, using tone burst (TB), in adult ears with normal hearing (NH). The secondary aim of this study is to ascertain the need of contralateral masking in ABR measurements with the TB stimuli using a 3A insertion earphone, and to propose the applicability of WN masking in unilateral sensorineural hearing loss (USNHL). RESEARCH DESIGN: It is a cross-sectional observational and descriptive study. STUDY SAMPLE: Experiment 1: Thirty individuals, without any otologic, psychological, or neurological dysfunction, were selected. Experiment 2: Fifteen individuals with previous audiological diagnoses of severe and profound USNHL were considered. INTERVENTION: The study involves ABR TB at specific frequencies of 0.5, 1, 2, and 4 kHz. DATA COLLECTION AND ANALYSIS: Experiment 1: The evaluation was performed at the fixed intensity of 80 dB nHL (decibel normalized hearing level) on the tested ear, followed by the application of simultaneous masking to the nontested ear, intensity ranged from 0 to 80 dB. Experiment 2: ABR threshold measurements were first performed on the ear with hearing loss (HL) at the frequencies of 1, 2, and 4 kHz. The results were subsequently confirmed using contralateral masking. RESULTS: Experiment 1: At any given frequency, there were no statistically significant differences in the amplitude and latency of V wave with increase in the intensities of WN masking. Experiment 2: Cross-hearing was observed at least once in all frequencies analyzed through the occurrence of V wave. CONCLUSION: In conclusion, the contralateral WN masking at the maximum intensity of 80 dB does not affect the amplitude and latency of V wave of the ABR TB at 1, 2, and 4 kHz. Contralateral masking for the ABR TB presented using 3A insertion earphones is necessary at 1, 2, and 4 kHz in individuals with severe or profound degrees of USNHL and at intensities of 15, 20, and 10 dB above the ABR threshold of the nontested ear.

ABSTRACT Purpose To elaborate a virtual tool, with didactic purposes, that allows the integration of technology to the teaching of Pure Tone Audiometry (PTA) and speech audiometry. Methods The Interacoustics AD229b audiometer was used as a physical model to achieve the virtual tool. The Visual Basic 6 programming language was used, so that the colors, characters, and functions were similar to the real audiometer. In addition, the possibility of simulating the patient's response was added, as well as of recording the hearing thresholds in a virtual audiogram. For speech audiometry, the possibility of adjusting the VU meter and recording the number of correct and incorrect answers were implemented. Results The developed tool was able to reproduce frequencies from 125 Hz to 8000 Hz, in intensities ranging from -10 to 110 dB, being possible to use different stimulus, as well as clinical masking by air and bone conduction. The microphone button can be used to facilitate the teaching of speech audiometry. Conclusion The virtual version of the audiometer is similar to the model equipment, making the integration of technology into teaching feasible, with exemplify the PTA and speech audiometry.

Nursing training program in children's hearing health: a proposal for interactive tele-education.

OBJECTIVE: To verify the effectiveness of a nursing training program in the area of children's hearing health using interactive tele-education. METHODS: Interrupted time series with non-random control group pre-test/ post-test. A cohort of 41 nurses, with no previous formal training in hearing health. A "Children's Hearing Health" Cybertutor was employed. The effectiveness of the nursing training was verified by comparing pre- versus post-training performance and by analyzing responses to an evaluation questionnaire. RESULTS: Following training, the performance was significantly better in all domains assessed and in the total score. The evaluation questionnaire demonstrated that the Cybertutor was well accepted and the performance revealed in the pre-training phase demonstrated the need for children´s hearing health training. CONCLUSION: The effectiveness of the nursing training program in the area of Children's Hearing Health using interactive tele-education could be proven, since there was an improvement in performance in all domains evaluated.

Unilateral and asymmetric hearing loss in childhood. / Perda auditiva unilateral e assimétrica na infância.

PURPOSE: To describe unilateral and bilateral asymmetric sensorineural hearing loss in children and its etiological, audiological and demographic characteristics. METHODS: Retrospective cross-sectional study developed in the Seção de Implante Coclear of Hospital de Reabilitação de Anomalias Craniofaciais, through the analysis of medical records. RESULTS: Data from 1152 patients were analyzed: 424 (37%) adolescents, adults or elderly, and 728 (63%) children, of whom 691 (95%) had bilateral symmetrical hearing loss, and 37 (5%) had unilateral hearing loss (n=10) or bilateral asymmetric (n=27) sensorineural hearing loss. The mean age at diagnosis of unilateral sensorineural hearing loss was 33.58±21.69 months, and for asymmetric bilateral it was 33.12±21.69 months, with a prevalence of 1.4% and 3.7%, respectively. The highest risk indicator for hearing loss for both groups was the family history of permanent deafness, which began in childhood. The majority of the relatives of children with unilateral sensorineural hearing loss presented the highest low socioeconomic classification (50%), while children with bilateral asymmetric sensorineural hearing loss were also be subdivided into upper (37%) and lower (37%). CONCLUSION: We observed a greater occurrence of asymmetric bilateral sensorineural hearing loss compared to unilateral hearing loss, as well as the hereditary risk indicator, with a predominance of the deep ear and female preponderance in both groups. Although neonatal hearing screening provides early identification of unilateral sensorineural hearing loss, the age at the audiological diagnosis is still above the recommended level. In addition, the majority of the children's family members presented a low level of income.

OBJETIVO: Descrever a perda auditiva sensorioneural unilateral e bilateral assimétrica em crianças quanto às características etiológicas, audiológicas e demográficas. MÉTODO: Estudo retrospectivo transversal, desenvolvido na Seção de Implante Coclear do Hospital de Reabilitação de Anomalias Craniofaciais, por meio da análise de prontuários. RESULTADOS: Foram analisados os dados de 1152 pacientes, sendo 424 (37%) adolescentes, adultos ou idosos e 728 (63%) crianças, dentre as quais, 691 (95%) apresentavam perda auditiva bilateral simétrica e 37 (5%) perda auditiva sensorioneural unilateral (n=10) ou bilateral assimétrica (n=27). A idade média ao diagnóstico na perda auditiva sensorioneural unilateral foi de 33,58±21,69 meses e na bilateral assimétrica de 33,12±21,69 meses, com prevalência de 1,4% e 3,7%, respectivamente. O indicador de risco para a deficiência auditiva de maior ocorrência para ambos os grupos foi o de antecedente familiar. A maioria dos familiares das crianças com perda auditiva sensorioneural unilateral apresentaram a classificação socioeconômica baixa superior (50%), enquanto que as crianças com perda auditiva sensorioneural bilateral assimétrica se subdividiram igualmente em baixa superior (37%) e média inferior (37%). CONCLUSÃO: Houve uma maior prevalência da perda auditiva sensorioneural bilateral assimétrica em relação à unilateral, bem como do indicador de risco de hereditariedade, com predomínio do grau profundo na pior orelha e preponderância do sexo feminino, em ambos os grupos. Apesar de a triagem auditiva neonatal propiciar a identificação precoce da perda auditiva sensorioneural unilateral, a idade no diagnóstico audiológico ainda se encontra acima do recomendado. Adicionalmente, a maioria dos familiares das crianças apresentou nível de rendimento baixo.
