Objectives: To assess the hearing benefits of cochlear implantation and its daily usage in children with single-sided deafness (SSD). We compared the results of children with congenital/perinatal deafness and those with acquired deafness and evaluated the impact of age at implantation on performance.
Design: There were 99 children with SSD in the study, all of whom had more than 14 months of experience with a cochlear implant (CI); 58 had congenital/perinatal SSD, while 41 had acquired SSD. The hearing benefit of the CI was measured with age-appropriate speech discrimination in noise tests and localization tests. Daily processor usage was obtained from parent interviews and datalogging.
Results: For speech discrimination in noise, children with congenital/perinatal SSD demonstrated advantages of binaural redundancy and head shadow, while children with acquired SSD additionally benefited from the binaural squelch effect. Significant improvements in sound localization following a cochlear implantation were observed in both groups, with the benefit being slightly greater in the acquired SSD group. The mean daily processor usage was 10.3 h/day as reported by parents, compared with 7.5 h/day as recorded by datalogging, with no significant difference between the groups. There was no significant correlation between age at implantation and the benefits of head shadow, redundancy, and squelch, or in improvements in localization or daily processor usage.
Conclusions: Cochlear implantation is an effective treatment for children with both congenital and acquired SSD.

Objectives: Alterations in auditory evoked potential (AEP) parameters have been associated with sensory memory deficits and may serve as biomarkers for cognitive decline. This systematic review and meta-analysis aimed to evaluate the effectiveness of AEPs in the early detection of Alzheimer disease (AD).
Design: The systematic review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 guidelines. A comprehensive search was performed across five electronic databases (EMBASE, Scopus, Cochrane Library, Web of Science, PubMed, and CINAHL) from their inception until August 2024, without restrictions on date or language. The methodological quality of evidence was assessed using the Crew Critical Appraisal Tool. Data were extracted on the latency and amplitude of five AEP components, including auditory P50 gating, mismatch negativity, and late-latency responses (N100, N200, P300), comparing patients with AD to age-matched control peers.
Results: Out of 437 publications, 54 articles were selected for review, with most rated as having high methodological quality. The analysis revealed a significantly larger P50 gating amplitude ( p < 0.001) in patients with AD. Furthermore, patients with AD demonstrated significantly prolonged latencies and reduced amplitudes for N100, N200, and P300 components ( p ≤ 0.001) compared with controls. Among all AEPs, P300 latency exhibited the largest effect size. Funnel plot analysis and Egger's regression test showed no evidence of publication bias.
Conclusions: Our findings support the clinical utility of AEPs in early AD detection, with the P300 response identified as the most accurate electrophysiological measure for distinguishing patients with AD from the control group. These results highlight the value of incorporating AEPs into clinical assessment protocols to enhance early-stage AD diagnosis and monitoring, thereby facilitating timely interventions and the development of personalized treatment strategies.
目的：听觉诱发电位（AEP）参数的改变与感觉记忆缺陷有关，并可能作为认知能力下降的生物标志物。本系统综述和荟萃分析旨在评估AEPs在阿尔茨海默病（AD）早期检测中的有效性。设计：系统评价按照2020年系统评价和荟萃分析指南的首选报告项目进行。在五个电子数据库（EMBASE、Scopus、Cochrane Library、Web of Science、PubMed和CINAHL）中进行了全面的检索，从它们成立到2024年8月，没有日期和语言的限制。使用船员关键评估工具评估证据的方法学质量。提取5个AEP分量的潜伏期和振幅数据，包括听觉P50门控、错配阴性和晚潜伏期反应（N100、N200、P300），并将AD患者与年龄匹配的对照组进行比较。结果：在437篇出版物中，54篇文章被选中进行审查，其中大多数被评为具有高方法学质量。分析显示，AD患者的P50门控振幅显著增大（p < 0.001）。此外，与对照组相比，AD患者表现出显著延长的潜伏期和降低的N100、N200和P300成分的振幅（p≤0.001）。在所有aep中，P300潜伏期表现出最大的效应量。漏斗图分析和Egger回归检验未发现发表偏倚的证据。结论：我们的研究结果支持aep在早期AD检测中的临床应用，P300反应被认为是区分AD患者与对照组最准确的电生理指标。这些结果突出了将AEPs纳入临床评估方案以加强早期AD诊断和监测的价值，从而促进及时干预和制定个性化治疗策略。

Objectives: Although the benefits of hearing devices in children with bilateral hearing loss are well established, evidence in unilateral hearing loss (UHL) remains limited. This study aimed to (i) examine whether device fitting influences the relationship between linguistic input and communication outcomes (language and functional listening) in young children with UHL, and (ii) assess whether consistency of device use affects this relationship.
Design: A longitudinal study included 43 device-fitted and 61 non-fitted children with UHL at 12 mo (mean worse-ear hearing level: 80.9 versus 86.7 dB HL), and a subset of 26 and 15, respectively, at 3 yrs. Linguistic input (adult word count [AWC], conversational turn count [CTC]), nonlinguistic input, and child vocalizations were measured using Language ENvironment Analysis. Language was assessed with the Australian English Developmental Vocabulary Inventory at 12 mo, Peabody Picture Vocabulary Test and Preschool Language Scales at 3 yrs, and child vocalization count at both ages. Functional listening was assessed using the Parent Evaluation on Aural/Oral Performance (PEACH) questionnaire. Linear regression examined whether device fitting influenced the associations between linguistic input and communication outcomes. Similar regression analyses were completed in fitted children to assess the influence of consistency of device use on the relationship between linguistic input and communication outcomes.
Results: Linguistic and nonlinguistic input did not differ by device status. In cross-sectional analyses, better language abilities were found in children with higher CTC at both 12 mo and 3 yrs. Better functional listening abilities were found in children with higher CTC at 12 mo. A similar but not significant trend existed at 3 yrs. Associations between outcomes (except child vocalization count) and AWC were all nonsignificant. The nature of the association between AWC or CTC and communication outcomes did not vary between the fitted and not-fitted children in any of these analyses. Likewise, consistency of device use did not influence the association between linguistic input and communication outcomes. In longitudinal analyses, CTC increased with age similarly in both groups, however, no associations were evident between early linguistic input and later communication outcomes.
Conclusion: Similar to children with bilateral hearing loss, better communication outcomes in children with UHL are associated with increased two-way conversations with caregivers. There was no evidence that device fitting or consistency in device use affected this association. Outcomes underscore the importance of interactive communication between caregivers and children, regardless of fitting status.
目的：虽然听力设备对双侧听力损失儿童的益处已经得到了很好的证实，但单侧听力损失（UHL）的证据仍然有限。本研究旨在(i)检查设备适配是否会影响UHL幼儿语言输入和沟通结果（语言和功能性听力）之间的关系，以及（ii）评估设备使用的一致性是否会影响这种关系。设计：一项纵向研究包括43名安装设备和61名未安装设备的儿童，12个月时患有UHL（平均听力水平较差：80.9对86.7 dB HL）， 3年时分别为26和15名。使用语言环境分析测量语言输入（成人字数、会话回合数）、非语言输入和儿童发声。12个月时使用澳大利亚英语发展词汇量表进行语言评估，3岁时使用皮博迪图片词汇测试和学前语言量表进行语言评估，以及两个年龄段的儿童发声计数。采用家长听力/口语表现评估问卷（PEACH）对功能性听力进行评估。线性回归检验了设备拟合是否影响语言输入和交流结果之间的关联。在适合的儿童中完成了类似的回归分析，以评估设备使用一致性对语言输入和交流结果之间关系的影响。结果：语言和非语言输入不受设备状态的影响。在横断面分析中，在12个月和3岁时，发现CTC较高的儿童有更好的语言能力。在12个月时，CTC较高的儿童的功能性听力能力较好。在3岁时，存在类似但不显著的趋势。结果（儿童发声计数除外）与AWC之间的关联均不显著。在这些分析中，AWC或CTC与沟通结果之间的关联性质在适合和不适合的儿童之间没有变化。同样，设备使用的一致性并不影响语言输入和交流结果之间的关联。在纵向分析中，CTC随年龄的增长在两组中相似，然而，早期语言输入和后来的交流结果之间没有明显的联系。结论：与双侧听力损失儿童类似，UHL儿童更好的沟通结果与与照顾者增加的双向对话有关。没有证据表明器械安装或器械使用的一致性会影响这种关联。结果强调了照顾者和儿童之间互动沟通的重要性，无论其适合状态如何。

<p><strong>Objectives: </strong>Adults with bilateral late-onset hearing loss are at risk for depression and altered cognitive performance. We were interested in whether an improvement in hearing after cochlear implantation (CI) was associated with changes in depression and cognitive performance and whether these changes were related. We hypothesized that 12 mo after CI, hearing ability (speech recognition and subjective hearing) and cognitive performance would improve, and depression would decrease compared with pre-CI status. Furthermore, we hypothesized a negative association between changes in depression and changes in cognition, such that subjects with a higher reduction in depression would show a higher improvement in cognition. We also investigated whether changes in hearing, depression, and cognition differed between younger (<60 yr old) and older CI users (≥60 yr old).</p><p><strong>Design: </strong>This cohort study took place at two tertiary referral centers.

Our inclusion criteria comprised an onset of hearing loss in adulthood (over 18 yr), severe to profound symmetrical bilateral sensorineural hearing loss, and an indication for CI (first CI). Exclusion criteria comprised retro-cochlear hearing loss, psychosis, below-average intelligence, visual impairment, and medical diagnoses with potential effects on cognition (such as neurodegenerative diseases). Twelve months after CI, the study population had decreased to 41 participants. The younger group (n = 20) was between 25 and 59 yr old, and the older group (n = 21) was between 60 and 75 yr old.

<p><strong>Objectives: </strong>Recent expansion of cochlear implant (CI) indications by Medicare to include patients with better preoperative speech recognition and by the United States Food and Drug Administration to include patients with single-sided deafness and asymmetric hearing loss has increased the number of patients who are candidates for a CI. This expansion has the potential to raise the demand for audiological services related to CI, including preoperative determination of CI candidacy and postoperative programming and evaluation of performance. In this study, we evaluated ways that audiological care facilitates or impedes access to care for adult CI candidates and recipients in CI programs across the United States. Such information will help determine if audiologists will be able to meet an increased demand for services resulting from these recent expansions in CI candidacy.</p><p><strong>Design: </strong>An electronic survey containing a total of 48 questions presented in either multiple choice or rank order format was distributed electronically and promoted on social media to audiologists working with adult CI candidates or recipients. Responses were collected from November 29, 2023, to January 16, 2024. The survey included questions regarding pre- and postoperative CI care provided to adults. Of these 48 questions, 21 were related to CI access and included appointment availability and wait times, appointment schedules and duration, procedures used to triage the need for follow-up care, and provision of telehealth.

<p><strong>Objectives: </strong>This study aimed to (1) assess the effects of residual hearing in the acoustic hearing (AH) ear on speech perception outcomes with ongoing unilateral cochlear implant (CI) use in children and (2) investigate factors related to hearing history that might affect these outcomes. Children with single-sided deafness (SSD) were compared to peers with hearing loss (HL) in the AH ear contralateral to their CI.</p><p><strong>Design: </strong>In total, 185 children who received a unilateral CI after limited durations of severe to profound HL {median (interquartile range [IQR]) = 1.9 (1.0 to 2.9) years} were included in this study. Of these, 43 (23.2%) had SSD and 142 (76.8%) used a contralateral hearing aid for mild to moderately-severe HL (PTA median [IQR] = 48.8 [42.5 to 63.8] dB HL, n = 39 [21.1%]) or severe to profound HL (PTA median [IQR] = 80.0 [72.1 to 85.5] dB HL, n = 103 [55.7%]) (bimodal device users). Median [IQR] age at implantation was 5.3 [3.1 to 10.6] years. Speech perception was measured in quiet (n = 182 children, average of 2.8 test sessions/child) and in co-located speech-weighted noise (+10 dB SNR) (n = 109 children, average of 2.0 test sessions/child) using word recognition tests. Spatial release of masking was measured to assess spatial separation benefits (n = 78 children, average of 1.6 tests/child).</p><p><strong>Results: </strong>Speech perception in the AH ear was better in children with SSD than bimodal device users in quiet ( p < 0.001), but group differences were smaller in noise, reflecting significantly reduced scores in the SSD group in noise compared to quiet ( p < 0.001, mean [SD] difference = 27.3 [2.6] rationalized arcsine units [RAU]). Speech perception scores when using the CI-alone were similar between the three groups in quiet and noise ( p > 0.05). In quiet, speech perception was asymmetric with better scores for the AH ear for children with SSD (mean [SD] = 30.7 [29.1] RAU) and for the CI ear for bimodal device users (mean [±SD] = -5.25 [±21.7] RAU for mild to moderately-severe and -27.2 [±30.9] RAU for severe to profound HL), and the bilateral benefit was the smallest for children with SSD ( p < 0.01). In noise, however, these group differences were only significant between children with SSD and those with a severe to profound HL in the AH ear ( p = 0.02 for interaural asymmetry, p = 0.03 for bilateral benefit). In addition, asymmetry toward the AH ear decreased and bilateral benefit increased in quiet with shorter durations of deprivation ( p < 0.01) and longer CI experience ( p = 0.01), but these predictors had no effect in noise. Last, aural preference, measured by spatial release of masking, was consistent with interaural asymmetry in speech perception in quiet ( p = 0.01).

<p><strong>Objectives: </strong>This study evaluated whether Coronavirus disease 2019 (COVID-19)-related decreases in device use and speech exposure in children with unilateral cochlear implants (CIs) persisted post-pandemic. It was hypothesized that CI use is lower in children with single-sided deafness (SSD) than in children using bimodal devices and that speech exposure has recovered to pre-pandemic levels.</p><p><strong>Design: </strong>Datalogs (n = 608) from children with unilateral CIs (n = 111) and good hearing in their non-implanted ear (unaided pure tone average <60 dB) were analyzed across the pre-pandemic, peri-pandemic (during the pandemic), and post-pandemic periods. Participants were separated into children with single-sided deafness using a CI (SSD-CI group, n = 70), and children using a CI and contralateral hearing aid (bimodal devices group, n = 41). They were further divided by age at the start of the pandemic (preschool-aged and school-aged). Datalogs were collected from October 1, 2013 to April 1, 2024, and included daily CI use, speech duration, and speech-in-noise sounds captured by the CI.</p><p><strong>Results: </strong>CI use was lower in the SSD-CI group (mean ± SD = 5.78 ± 3.06 hours/day) than in the bimodal devices group (7.24 ± 3.75 hours/day, p = 0.013). In addition, of 17 children lost to follow-up, 14 were in the SSD-CI group. Preschool-aged children showed a steeper increase in CI use over time from CI activation in the bimodal devices group (slope ± SE = 0.96 ± 0.14 hours/day per year) than the SSD-CI group (0.15 ± 0.19 hours/day per year, p < 0.001).

Objectives: Auditory processing underlies phonological representation and presents neural oscillation lateralization in the brain. Atypical lateralization in auditory processing has been widely accepted as associated with impaired reading skills in alphabetic languages. However, whether Chinese adults with a reading difficulty (RD) history present atypical lateralization in auditory processing similar to that in alphabetic languages remains unknown. The purpose of this study was to investigate whether Chinese adults with poor reading would show atypical lateralization of neural oscillations during auditory sampling.
Design: Thirty-two adults with self-reported RD history and 44 adults without RD history were screened using the Chinese Adult Reading History Questionnaire. Reading accuracy, phonological accuracy, and rapid automatized naming (RAN) were assessed in all the participants. Auditory steady-state responses modulated at 10 to 80 Hz were recorded during a 5.4-sec white noise. Time-frequency power and phase synchrony indices were used to measure induced oscillatory power and synchrony of beta and gamma oscillations related to phonemic processing.
Results: Adults with a RD history performed worse than adults without RD history in reading accuracy and phonological accuracy. Adults with a RD history showed atypical rightward lateralization in the gamma band oscillation, whereas the adults without a RD history showed leftward lateralization. Adults with a RD history also demostrated reduced left-hemisphere oscillatory power and weaker bilateral synchrony. Event-related spectral perturbation in the left hemisphere correlated with reading accuracy in adults with RD history, while left-hemisphere lateralization of event-related spectral perturbation correlated with phonological accuracy in adults without RD history. In adults with RD history, the inter-trial phase synchrony in the left hemisphere correlated with RAN, and inter-trial phase synchrony in the right hemisphere correlated with reading accuracy and RAN, respectively.
Conclusions: Adults with RD history demonstrated atypical rightward gamma band lateralization compared with adults without RD history, alongside reduced left-hemisphere oscillatory power and weaker bilateral synchrony. These neural patterns correlated with reading accuracy and phonological skills, supporting the hypothesis that auditory lateralization deficits underlie phonological processing challenges in Chinese, mirroring mechanisms observed in alphabetic languages.
