Quality of Life in Children with Hearing Impairment: Systematic Review and Meta-analysis

The Validity and Reliability of the Turkish Version of Preschool Hearing Environments and Reflection on Quality of Life Questionnaire

PURPOSE

The purpose of this study was to assess preschool children's hearing-related quality of life and to introduce the scale, originally titled "Preschool Hearing Environments and Reflections on Quality of Life Questionnaire" (Preschool HEAR-QL), to the literature through Turkish adaption, validity, and reliability analyses.

METHOD

Our study included 210 children aged 2-6 years: 110 with hearing loss (56 cochlear implant users and 54 hearing aid users) and 100 with normal hearing. Demographic data were collected and then the Preschool HEAR-QL, which was translated into Turkish, was administered twice at 15-day intervals. Confirmatory factor analysis was used to determine whether the factor structure found in the original scale development study was confirmed in our sample (construct validity). Cronbach's alpha, intraclass correlation scores, and the test-retest method were used to assess the scale's reliability as the findings were analyzed using paired samples t tests.

RESULTS

The children with hearing loss had lower scores than their normal-hearing peers, and the difference was significant in the subdomains of behavior and attention, hearing environments, and communication. The subscale of the Preschool Period Listening Environments and their Reflections on Quality of Life Scale consists of 23 items, and Cronbach's alpha value was found as 0.922 in the first application and 0.926 in the second application (high reliability). In the model established for validity analysis, χ2/df = 2.156, root-mean-square error of approximation = 0.074, standard root-mean-square residual = 0.078, goodness-of-fit index = 0.830, adjusted goodness-of-fit index = 0.789, comparative fit index = 0.895, and Tucker-Lewis index = 0.881 (good model fit). In terms of test-retest reliability, the correlation between the two measurements was 0.837, and there was no statistical difference between the test-retest scores (p = .15).

CONCLUSION

The Turkish version of the Preschool HEAR-QL scale was proven to be a valid and reliable scale for assessing the hearing-related quality of life of children aged 2-6 years.

Bullying, Peer Victimization, and Quality of Life in Pediatric Hearing Loss Patients: A Pilot Study

OBJECTIVE

The primary objective of this pilot study is to describe the impacts of bullying and peer victimization (BPV) in children with hearing loss.

STUDY DESIGN

Prospective clinical survey study.

METHODS

This pilot study enrolled children between 8 and 18 years who were administered validated surveys at an outpatient clinic between July 2020 and March 2022. Surveys included health-related quality of life questionnaires (PedsQL and EQ-5D-Y), along with bullying and peer victimization questionnaires ("My Life in School" and the multidimensional peer victimization scale). Responses were scored with multivariate analysis. Clinical histories and active ICD-10 codes were also collected.

RESULTS

About 105 patients were recruited with a mean age of 13.1 years (SD = 3.15) and hearing loss (n = 30) among the top otolaryngological diagnoses. When surveying patients with hearing loss, 50.0% (n = 15) actively used a hearing aid device. Children (ages 8-12 years) with hearing loss reported a significantly lower psychosocial health-related quality of life than their peers without hearing loss (P = .007), though this was not the case for adolescents (ages 13-18 years) with hearing loss (P = .099). These trends did not change significantly before or after students resumed in-person classes. Children who wore hearing aids did not report a different BPV level than their peers.

CONCLUSION

In this small sample of school-aged children, any hearing loss, even with mild severity, was associated with diminished health-related quality of life; however, this was unrelated to hearing aid use. Wearing a hearing aid did not appear to be linked to higher bullying and peer victimization rates. Along with further studies on BPV with larger sample sizes, the findings in this study may help physicians counsel parents and children on the psychosocial aspects of hearing loss treatment and guide care decisions.

Impact of Hearing Loss on Social Participation in Children: A Scoping Review

Social participation can be defined as involvement in activities that provide a platform to interact with society and others. Untreated hearing loss effects communication skills, academic achievements, and peer-group interaction. Since a typical body structure and body functioning are essential to demonstrate day to day activities. Altogether these factors can influence the social participation in children with HL. The aim of this study is to systematically review the impact of hearing loss on social participation in children.A literature search was carried out to obtain studies exploring social participation among children with HL. Two authors independently searched four electronic databases, PubMed, Scopus, Embase, and Web of Science. The search strategy was designed by using six main terms 'social participation', 'social engagement', 'social interaction', 'hearing loss', 'hearing impairment', 'hearing disorder', and Boolean operators 'AND', 'OR' were used to make the search strings. The current review included four studies after meeting the eligibility criteria. Findings showed that social participation is affected in children with HL. Reduced hearing ability is one of the factors of reduced social participation in children. Children using hearing aids or cochlear implants, participate more frequently in social activities. The findings of this review suggest that HL is associated with reduced social participation. However, using hearing aids and cochlear implants followed by auditory verbal therapy has significant improvement in social participation. Future studies need to investigate whether early rehabilitation can increase social participation in children.

Hearing Loss: Genetic Testing, Current Advances and the Situation in Latin America

Congenital hearing loss is the most common birth defect, estimated to affect 2-3 in every 1000 births, with ~50-60% of those related to genetic causes. Technological advances enabled the identification of hundreds of genes related to hearing loss (HL), with important implications for patients, their families, and the community. Despite these advances, in Latin America, the population with hearing loss remains underdiagnosed, with most studies focusing on a single locus encompassing the GJB2/GJB6 genes. Here we discuss how current and emerging genetic knowledge has the potential to alter the approach to diagnosis and management of hearing loss, which is the current situation in Latin America, and the barriers that still need to be overcome.

Fatigue and Quality of Life in Children with Hearing Loss or Obstructive Sleep Apnea

OBJECTIVE

To investigate the fatigue levels of children with hearing loss (HL) and obstructive sleep apnea (OSA), hypothesizing that the fatigue experienced by children with HL is under-recognized.

STUDY DESIGN

Cross-sectional survey.

METHODS

We identified children aged 2-18 with HL, OSA, sleep-disordered breathing (SDB), and controls from a pediatric otolaryngology clinic and sleep center. Children and/or parents completed the Pediatric Quality of Life Inventory Multidimensional Fatigue Scale (PedsQL MFS), Hearing Environments And Reflection on Quality of Life (HEAR-QL), and OSA-18.

RESULTS

Responses of 50 children with HL, 79 with OSA, and 18 with SDB were compared with those of 49 recruited controls (RC) and literature controls (LC). Children with HL or OSA had higher fatigue than controls in the PedsQL MFS self-reported (HL 65.4, OSA 54.7, RC 71.8, LC 80.5, p < 0.001) and parent-reported (HL 64.6, OSA 59.3, RC 75.2, LC 89.6, p < 0.001). Children with HL had Cognitive Fatigue similar to that of children with OSA (self 60.4 vs. 49.5, p = 0.170; parent 56.0 vs. 56.7, p = 0.998), though with decreased Sleep/Rest Fatigue (self 67.8 vs. 56.3, p = 0.033; parent 69.8 vs. 57.5, p = 0.001). Children with HL or OSA had lower disease-related quality of life (QOL) than controls in the HEAR-QL and OSA-18, respectively. Stratification with disease severity revealed no differences in fatigue.

CONCLUSION

Children with HL or OSA experience higher fatigue and lower QOL than controls. Similar Cognitive Fatigue in both groups suggests under-recognized fatigue in children with HL.

Use of Socioeconomic Demographic Data in Studies on Pediatric Unilateral Hearing Loss: A Scoping Review

OBJECTIVES

Social determinants of health (SDOH) (healthcare access and quality, education access and quality, socioeconomic status, social and cultural context, neighborhood and built environment) ( Healthy People 2030 ) have been shown to impact a wide range of health-related outcomes and access to care. Given the medical and nonmedical costs associated with children with unilateral hearing loss (UHL), the varied insurance coverage for hearing healthcare services, and the differences in hearing aid utilization rates between children of different sociodemographic classes, the sociodemographic information of children with UHL enrolled in research studies should be collected to ensure the generalizability of hearing healthcare interventions. Therefore, the objective of this scoping review is to assess the reporting of SDOH data for participants in studies of pediatric UHL and its comparison to population trends.

DESIGN

Two searches of published literature were conducted by a qualified medical librarian. Two reviewers then evaluated all candidate articles. Study inclusion parameters were from 2010 to present, peer-reviewed studies with prospective study design, and participant population including children (age 0 to 18 years old) with UHL.

RESULTS

Two literature searches using PubMed Medline and Embase found 442 and 3058 studies each for review. After abstract and paper review, 87 studies were included in final qualitative review, with 22 of these studies reporting race distribution of participants, 15 reporting insurance status or family income, and 12 reporting the maternal education level.

CONCLUSIONS

Sociodemographic data are not commonly reported in research studies of children with UHL. In reported samples, research participants are more likely to have private insurance and higher family income compared with overall population distribution. These demographic biases may affect the generalizability of study results to all children with UHL. Further evaluation is warranted to evaluate whether participant recruitment affects outcomes that reflect the overall population.

Hearing Impairment and School Engagement Outcomes in US Children

Importance

Ensuring appropriate school engagement for deaf or hard of hearing (DHH) children in the US is important for improving their long-term outcomes as they grow into adults.

Objective

To examine the associations between hearing loss (HL), its sequelae (speech and/or language disorders, behavioral and/or conduct problems, and neuropsychiatric and/or learning disorders), and various school engagement measures among school-aged children in the US.

Design, Setting, and Participants

This cross-sectional study combined data from the nationally representative 2016-2021 National Survey of Children's Health. A total of 155 178 randomly selected children (weighted, approximately 49 340 700 children) aged 6 to 17 years with a parent or caregiver who responded to an address-based survey by mail or online were included. All analyses were weighted to account for the probability of selection and nonresponse and to reflect population-based estimates representative of all noninstitutionalized school-aged US children and adolescents residing in housing units.

Main Outcomes and Measures

Diverse school engagement measures, including extracurricular participation in sports, clubs, paid work, volunteer work, and organized lessons, as well as educational performance variables, including missed school days, not caring about doing well in school, not doing required homework, grade repetition, and parent or guardian contacted by school.

Results

Of the estimated 49 340 700 children aged 6 to 17 years (41.1% aged 6-10 years; 51.1% male; 54.7% without underrepresented minority status), an estimated 1.4% (95% CI, 1.2%-1.5%) were reported by their parent or guardian to have deafness or hearing problems. Having DHH status was associated with significantly worse outcomes on 8 of 10 school engagement measures (eg, participation in sports: adjusted odds ratio [AOR], 0.75 [95% CI, 0.60-0.93]; missed school days: AOR, 2.98 [95% CI, 2.21-4.00]), even after adjustment for age, sex, underrepresented minority status, highest educational level of parent or guardian, federal poverty level of the household, and primary language in the household. Moreover, although subgroup analyses of DHH children with and without HL sequelae revealed significant differences (speech and/or language disorder: AOR, 5.83 [95% CI, 4.31-7.89]; behavioral and/or conduct problem: AOR, 2.75 [95% CI, 2.10-3.60]; neuropsychiatric and/or learning disorder: AOR, 3.06 [95% CI, 2.39-3.91]), HL sequelae only partially mediated the associations between these disparities.

Conclusions and Relevance

In this cross-sectional study, DHH status itself may have been the primary factor directly associated with school engagement disparities. These findings suggest the need for greater emphasis on educational accommodations and support for hearing status itself, independent of the presence or absence of HL sequelae.

Circulating IL-17 reduces the risk of cisplatin-induced hearing loss in children: a bidirectional two-sample Mendelian randomization study

Studies have reported that cytokines and their related signaling pathways play a role in inner ear diseases. In clinical practice, approximately 50% of pediatric cancer patients experience irreversible hearing loss after cisplatin treatment. However, currently, there is a lack of systematic research on the causal relationship between circulating cytokines and cisplatin-induced hearing loss in children. Genetic variant data for 41 circulating cytokines were obtained from a meta-analysis of genome-wide association studies (GWAS) among 8293 individuals of Finnish descent. The GWAS data for Cisplatin-induced hearing loss in children were derived from a multicenter cohort of European pediatric cancer patients and survivors (N = 390), including both cases with hearing loss after cisplatin chemotherapy and controls without hearing loss. Multiple methods were employed for bidirectional Mendelian randomization (MR) estimation. Bonferroni correction was applied to adjust the original P-values, followed by a series of sensitivity analyses. In the directional Mendelian randomization (MR) analysis, it was found that IL-17 was significantly associated with a reduced risk of Cisplatin-induced hearing loss in children (OR: 0.18, CI: 0.06-0.48, P < 0.001, FDR = 0.041). In the reverse MR analysis, there were some nominal causal relationships of Cisplatin-induced hearing loss in children with certain cytokines [M-CSF: (OR: 1.04, CI: 1.01-1.08, P = 0.010, FDR = 0.41); IL-2RA: (OR: 1.03, CI: 1.00-1.05, P = 0.044, FDR = 0.447); MIP-1β: (OR: 1.02, CI: 1.00-1.04, P = 0.041, FDR = 0.447)]. leave-one-out analysis demonstrated that only M-CSF exhibited stability. These findings reveal a causal relationship between IL-17 and cisplatin-induced hearing loss in children. Further research is needed to determine the potential protective mechanisms of IL-17 in cisplatin-induced ototoxicity.

Health-related quality of life and associated developmental domains of children provided early with cochlear implants

OBJECTIVES

Quality of life plays an important place in the psychosocial development of children with Cochlear Implants (CI). We assesd health-related quality of life (HRQoL) in children with CI and in hearing children and determined relationships between HRQoL and other developmental characteristics (social-emotional development, Theory of Mind (ToM), spoken language skills).

METHODS

A longitudinal study was conducted including children with CI and hearing children. We used instruments that are widely employed and have been validated for research. At time 1 social-emotional development, ToM and spoken language skills were assessed.HRQoL was assessed using the generic KINDL questionnaire, as was social-emotional development, 2.5 years later (time 2).

RESULTS

No significant difference was seen in HRQoL between hearing children and children with CI. We show that the age of detection, the age of hearing care, and the start of early intervention are not related to HRQoL of children with CI, but relationships with some domains of social-emotional development are evident.

CONCLUSIONS

This study highlights the importance of targeted intervention not only to improve spoken language skills at preschool age, but also strengthen social-emotional and social-cognitive competences.

Development of mental health and psychosocial support (MHPSS) guidelines for deaf and hard of hearing children in the Gaza Strip

Deaf and hard of hearing children in the Gaza Strip may be at risk of mental health conditions and psychological distress, as a result of social exclusion and limited accessible communication. This article presents the process and research methods used to develop guidelines for schools in the Gaza Strip on mental health and psychosocial support for deaf and hard of hearing children. The process was guided by the GIN-McMaster guideline development checklist across four steps: (1) priority settings; (2) searching for evidence; (3) developing recommendations; (4) evaluation. Priority setting was spearheaded by local and international researchers, and a local steering committee comprised of deaf and hard of hearing representatives, school administration and staff, mental health specialists, family members and government officials. In searching for evidence, and in order to generate evidence-based recommendations for the guidelines, we utilised a scoping review of global mental health support for deaf and hard of hearing children and qualitative research with deaf and hard of hearing children and adults, families and teachers. Two pilot studies were conducted in mainstream and specialist educational settings as way of evaluation. The scoping review and qualitative research identified various content for the guidelines, including the importance of information on disability and deafness, promoting social inclusion and self-esteem, and accessible learning environments. The pilot studies demonstrated feasibility and acceptability among teachers and deaf and hard of hearing children, although teachers need sufficient support and resources to implement. Now finalised, the guidelines are being distributed to schools in the Gaza Strip to support the mental health and wellbeing of deaf and hard of hearing children.

Communication, academic and social outcomes of childhood cancer survivors with hearing loss: A systematic review

Many children treated for cancer are at risk of hearing loss. However, little is known about how hearing loss impacts their communication, academic and social outcomes. To examine the impact, this systematic review aimed to synthesise and appraise quantitative and qualitative studies reporting on (i) participants with hearing loss treated with platinum-based chemotherapy or cranial radiotherapy during childhood; and (ii) speech, language, academic performance, or social participation findings. Systematic database searches yielded 23 relevant articles that were analysed using narrative synthesis. Difficulties were reported for some but not all communication, academic and social aspects; however, a quality assessment using Grading of Recommendations Assessment, Development and Evaluation (GRADE) revealed low to very low certainty in the findings. Future research should aim to increase the quality of the research evidence and explore how multidisciplinary services can provide evidence-based support for childhood cancer survivors with competing hearing, communication, and social difficulties.

First results of the Strengths and Difficulties Questionnaire, applied as a screening tool for psychosocial difficulties in pediatric audiology

PURPOSE

Despite major improvements in rehabilitation possibilities, children with sensorineural hearing loss are at risk for psychosocial difficulties. These difficulties can impact their educational and career achievements and may be two to three times more common in children with hearing loss compared to those with normal hearing. Early identification of psychosocial difficulties can be facilitated using the Strengths and Difficulties Questionnaire (SDQ) and may improve outcomes and quality of life. We implemented the SDQ into the clinical follow-up of children with hearing loss in a tertiary referral hospital. With this, prevalence and severity of difficulties in specific psychosocial domains and several predictors were investigated.

METHODS

A retrospective, cross-sectional investigation was performed of the following factors in association with the SDQ results: type of hearing device, type and degree of hearing loss, speech perception in quiet and in noise, and type of schooling.

RESULTS

Between June 2020 and January 2022, parents of 312 children (age 4-18) completed the SDQ. An additional 113 child-reports were completed. The response rate of the parents was 69%. Problems with peer relationships and prosocial behavior were the most affected areas with clinically elevated scores in 22% of the children. Psychosocial difficulties were distributed similarly across types of hearing device, nature and degrees of hearing loss, and educational settings. Better speech perception in quiet was significantly associated with fewer parent-reported conduct problems.

CONCLUSION

The results of the present study suggest that children with hearing loss may be at risk of experiencing challenges with social interactions and attachment in social contexts. Using the SDQ in clinical follow-up may improve the chances for early psychological assessment and intervention. In addition, the study found that children's mental health may be impacted by their communication abilities.

Language and health-related quality of life outcomes of children early-detected with unilateral and mild bilateral hearing loss

Introduction

We aimed to describe the language and health-related quality of life (HRQoL) outcomes of children early-identified with unilateral or mild bilateral permanent hearing loss. This was a cross-sectional community-based study of children with mild bilateral or unilateral permanent hearing loss (including unilateral auditory neuropathy spectrum disorder (ANSD)), drawn from a population-based databank in Victoria, Australia.

Methods

Enrolment in this databank is independent of early intervention and amplification approaches. Language and caregiver-reported HRQoL outcomes are described by type and degree of loss at three timepoints across child development: at age 2 years (n = 255), 5-7 years (n = 173) and 9-12 years (n = 45).

Results

Across all age groups, average language outcomes were poorer than population normative scores by between a half to two thirds of a standard deviation. Children with mild bilateral hearing loss demonstrated poorer average language outcomes than children with unilateral hearing loss, particularly at younger ages. Children with unilateral ANSD showed language outcomes comparable to their peers with unilateral profound hearing loss. Children had poorer HRQoL psychosocial scores compared to physical scores, without obvious patterns of outcomes linked to degree or type of hearing loss.

Discussion

This study demonstrates children with early-identified unilateral or mild bilateral hearing loss have average language and HRQoL outcomes poorer than population normative expectations from an early age. These outcomes are observed at later ages across childhood. These findings provide a contemporary description of language and quality of life outcomes for children identified but not targeted by universal newborn hearing screening and raise questions of how to provide better support for these populations of children and their families.

Cochlear Implantation and Educational and Quality-of-Life Outcomes in Adolescence

Importance

Cochlear implants (CIs) have been shown to be effective in improving auditory skills and speech and language development. However, less is known about the long-term outcomes of CIs on educational functioning or quality of life.

Objective

To evaluate long-term educational outcomes and quality of life in adolescents over 13 years postimplantation.

Design, Setting, and Participants

This longitudinal cohort study included 188 children with bilateral severe to profound hearing loss with CIs from the Childhood Development After Cochlear Implantation (CDaCI) study from hospital-based CI programs; a cohort of 340 children with severe to profound hearing loss without CIs from a nationally representative survey (National Longitudinal Transition Study-2; NLTS-2), and results from the literature of comparable children without CIs.

Exposure(s)

Cochlear implantation (early and late).

Main Outcomes and Measures

Adolescent performance on measures of academic achievement (Woodcock Johnson), language (Comprehensive Assessment of Spoken Language), and quality of life (Pediatric Quality of Life Inventory, Youth Quality of Life Instrument-Deaf and Hard of Hearing).

Results

The CDaCI cohort included 188 children, 136 of whom completed the wave 3 postimplantation follow-up visits (77 [55%] female) with CIs; mean [SD] age was 11.47 [1.27] years. The NLTS-2 cohort included 340 children (50% female) with severe to profound hearing loss without CIs. Children with CIs had better academic performance compared with children without CIs with similar levels of hearing loss. The largest benefits were seen for children who received implants early (prior to age 18 months), who performed at or above age and gender norms for language and academic achievement. Similarly, adolescents with CIs reported better quality of life on the Pediatric Quality of Life Inventory compared with children without CIs. On a condition-specific measure (Youth Quality of Life Instrument-Deaf and Hard of Hearing), children who received implants early scored higher across all 3 domains than comparisons without CIs.

Conclusions and Relevance

To our knowledge, this is the first study to evaluate long-term educational outcomes and quality of life in adolescents using CIs. This longitudinal cohort study showed better outcomes of CIs in terms of language, academic performance, and quality of life. While the greatest benefits were observed for children who received implants before age 18 months, benefits were also noted for children who received implants later, providing evidence that children with severe to profound hearing loss with CIs can achieve at or above expected levels compared with hearing peers.

Parent Awareness and Perceived Barriers Regarding Hearing Impairment among School Age Children in Taif Region of Saudi Arabia

Background

Hearing impairment (HI) is the most common global disabling condition. It is a considerable public health condition in childhood that is associated with long-term socio-emotional-academic, and communication difficulties. The current study explored the knowledge and awareness of HI among school-age children and its related factor in Taif, Saudi Arabia.

Materials and Methods

A cross-sectional study was done on 268 Saudi school-age children in the population of the Taif region of Saudi Arabia. A predesigned questionnaire was used to collect their demographic data, consanguinity, education level, and academic performance.

Results

About 45.9% of parents had good awareness related to hearing loss and its impact on children's life. Only 19% (n = 51) of parents reported that their children encountered language problems in communicating with others. When we assessed the relationship between this language problem and academic performance, it was found that children with language problems had below-average academic performance (P < 0.001).

Conclusion

The study showed that parents' awareness about children's hearing was not that satisfactory, and there was a considerable amount of difficulties faced by the children in their personal and social life due to these hearing problems. It is imperative to create awareness among the public regarding various modifiable risk factors of HI by conducting health awareness campaigns.

Communication, inclusion and psychological wellbeing among deaf and hard of hearing children: A qualitative study in the Gaza Strip

Deaf and hard of hearing children are at risk of exclusion from community life and education, which may increase their risk of mental health conditions. This study explores the experience of deaf and hard of hearing children in the Gaza Strip, with particular focus on the factors that contribute to psychological wellbeing and distress. In-depth interviews were conducted with 17 deaf and hard of hearing children, 10 caregivers of deaf and hard of hearing children and eight teachers of deaf and hard of hearing children in mainstream and special schools, across the Gaza Strip. Further, three focus group discussions were held with deaf and hard of hearing adults and disability leaders, mental health specialists and other teachers of deaf and hard of hearing children. Data collection was completed in August 2020. Key themes identified in the analysis included lack of accessible communication, community exclusion, negative attitudes towards hearing impairment and deafness and the impact on deaf and hard of hearing children's sense of self, and limited family knowledge on hearing impairment and deafness. Further findings focused on strategies to improve the inclusion of deaf and hard of hearing children and how to promote wellbeing. In conclusion, participants in this study believed that deaf and hard of hearing children in the Gaza Strip are at increased risk of mental health conditions. Changes are needed across community and government structures, including education systems, to promote the inclusion of deaf and hard of hearing children and to support their psychological wellbeing. Recommendations from the findings include increasing efforts to improve awareness and reduce stigma, providing better access to sign language for deaf and hard of hearing children, and offering training for teachers of deaf and hard of hearing children, especially in mainstream environments.

Translation and Validation of the Hearing Environments and Reflection on Quality of Life (HEAR-QL) Questionnaire for Children and Adolescents in Arabic

Background There are numerous quality-of-life (QoL) assessment tools available; however, only a few are designed specifically for children with chronic conditions. Among these assessment tools are the Hearing Environments and Reflection on QoL questionnaires for children (HEAR-QL26, HEAR-Q28) developed by Washington University. Unfortunately, there are no other tools that assess hearing loss, and none of them are in Arabic. This paper aims to adapt the HEAR-QL to Arabic and provide an accessible method of measuring the QoL of children with hearing loss in our Arabic-speaking populations. Methodology An independent medical translator translated the HEAR-QL26 and HEAR-QL28 into Arabic. The translations were then examined by two bilingual, native Arabic-speaking otolaryngologists who modified the inadequate questions. Back-translation of the Arabic version into English was subsequently performed by an independent translator. Intra-rater reliability was tested for each of HEAR-QL26 and HEAR-QL28 using 10 participants for each survey, where the participants answered the surveys twice with a period of two weeks between them. A pilot study was conducted which had a total of 40 participants divided equally between the two surveys where each group had an equal number of hearing participants and participants with hearing loss. Results Both HEAR-QL26 and HEAR-QL28 were validated with an overall intra-rater reliability of 88.85% and 87.86% respectively. In the pilot study, the HEAR-QL26 participants with normal hearing scored a median of 2437.5, while the participants with hearing loss scored a median of 1837.5 (p = 0.001). Moreover, HEAR-QL28 participants had a median score of 2725 among participants with normal hearing and 1725 for participants with hearing loss (p = 0.001). Conclusion HEAR-QL is a well-established QoL in children with hearing loss. The validated Arabic adaptation can now be used to measure deafness in Arabic-speaking children.

Deaf and hard-of-hearing children and adolescents' mental health, Quality of Life and communication

Mental health problems and lower Quality of Life (QoL) are more common in deaf and hard-of-hearing - (D)HH - children than in typically hearing (TH) children. Communication has been repeatedly linked to both mental health and QoL. The aims of this study were to compare mental health and QoL between signing deaf and hard-of-hearing (DHH), hard-of-hearing (HH) and TH children and to study associations between mental health/QoL and severity of hearing loss and communication. 106 children and adolescents (mean age 11;8; SD = 3.42), 59 of them DHH and 47 HH, and their parents reported child mental health and QoL outcomes. Parents also provided information about their children's communication, hearing loss and education while their children's cognitive ability was assessed. Although (D)HH and their parents rated their mental health similar to their TH peers, about twice as many (D)HH children rated themselves in the clinical range. However, (D)HH children rated their QoL as similar to their TH peers, while their parents rated it significantly lower. Associations between communicative competence, parent-reported mental health and QoL were found, whereas severity of hearing loss based on parent-report had no significant association with either mental health or QoL. These results are in line with other studies and emphasise the need to follow up on (D)HH children's mental health, QoL and communication.

Hearing outcomes in children with pneumococcal meningitis in the PCV13 era

INTRODUCTION

Streptococcus pneumoniae, is associated with the highest incidence of post-meningitic SNHL. The exact impact of 13-valent pneumococcal conjugate vaccine (PCV) on pediatric SNHL from pneumococcal meningitis is unknown. We aimed to identify clinical factors associated with post-meningitic SNHL (pmSNHL) from pneumococcal meningitis and describe its rates based on three time periods: pre-PCV, PCV-7 and PCV13 eras.

METHODS

A retrospective case-control study was performed for patients 18 years and younger diagnosed with pneumococcal meningitis from January 1, 2010 to December 31, 2020 at Children's Hospital Colorado. Demographic and clinical risk factors between those with or without SNHL were compared. Detailed hearing outcomes of those with resulting SNHL are described.

RESULTS

23 patients with CSF cultures or Meningitis/Encephalitis Panel positive for pneumococcal meningitis were identified. Twenty patients both survived the infection and had audiologic evaluation. Six patients had pmSNHL, with 50 % affected bilaterally. The rate of pmSNHL from S. pneumoniae in the PCV-13 era at our institution was similar to historical rates from the pre-PCV and PCV-7 eras. Similar proportions of patients with pmSNHL completed PCV vaccination (66.7 %) compared to those without (71.4 %). Non-PCV-13 serotypes were responsible 83 % of patients with pmSNHL versus 57 % of patients without pmSNHL.

CONCLUSIONS

Despite high rates of PCV-13 uptake in our cohort, pmSNHL was still common, severe, and commonly associated with non-PCV-13 serotypes. Non-PCV-13 serotypes may be contributing to the persistently high rate of post-meningitic SNHL and the severity of SNHL. Newer pneumococcal conjugate vaccines with expanded serotypes may help mitigate the SNHL associated with pneumococcal meningitis.

Pediatric cochlear implant explantation and reimplantation over a 32-year period

OBJECTIVES

Cochlear implantation is indicated for pediatric patients with bilateral severe to profound sensorineural hearing loss. The literature reports large variability in cochlear implant (CI) device survival and rates of explantation and reimplantation. This retrospective chart review summarizes CI survival and rates of explantation and reimplantation in pediatric CI recipients at a Canadian tertiary pediatric hospital over 32 years.

METHODS

A retrospective chart review of all pediatric patients who received a Cochlear Corporation® CI between April 1988 and June 2020 was undertaken. Rates of explantation/reimplantation were collected and categorized based on device type and reason for failure (medical, device, and inconclusive failure). Device survival analysis based on implant model was also completed utilizing Kaplan-Meier curves.

RESULTS

512 CIs were implanted over the 32-year period by four surgeons (77.1%, 18.16%, 4.49%, and 0.20%, respectively). Patient age ranged from seven months to 20.4 years. The overall explantation and reimplantation rate was 3.32% (17/512 implants), with seven as a result of device failure (1.37%), nine events of medical failure (1.76%), and one inconclusive failure (0.20%). Cumulative CI survival rates at 5, 10, 15, and 20 years were 98.15%, 96.33%, 95.53%, and 94.39%.

CONCLUSION

The overall institutional CI failure, explantation, and reimplantation rates are lower than the average reported rates in the literature.

Validity, Discriminative Ability, and Reliability of the Turkish Hearing-Related Quality of Life Questionnaire for Children and Adolescents

PURPOSE

The aim of this study was to translate the versions of the Hearing Environments and Reflection on Quality of Life (HEAR-QL) into Turkish and investigate the validity and reliability of the Turkish 26-item HEAR-QL (HEAR-QL-26) for children and Turkish 28-item HEAR-QL (HEAR-QL-28) for adolescents.

METHOD

The protocol included translation into Turkish and linguistic adaptation. The HEAR-QL-26 and HEAR-QL-28, respectively, were administered to 249 children (130 with hearing loss, 119 without hearing loss) and 249 adolescents (140 with hearing loss, 109 without hearing loss) between the ages of 8 and 18 years. To determine the internal consistency (reliability) of the Turkish HEAR-QL scale, Cronbach's alpha coefficient (α) was calculated for the subcategories and the total score. We measured the construct validity of the Turkish HEAR-QL-26 and HEAR-QL-28 using Pearson r correlation coefficients comparing the Turkish HEAR-QL and the Turkish Child and Adolescent Quality of Life Scale (PedsQL).

RESULTS

The reliability for both children and adolescents (Cronbach's alpha = .973 for HEAR-QL-26 and .977 for HEAR-QL-28) was high, and test-retest reliability showed strong to excellent correlations (intraclass correlation coefficient = .980 and .979, respectively) for the total scores. In terms of known-group validity, the total HEAR-QL mean scores were lower for participants with hearing loss than for children/adolescents with normal hearing (p < .05). Confirmatory factor analysis showed that the number of original items was sufficient in the Turkish version. Both HEAR-QL versions provided a higher area under the curve (AUC = .984 and .972, respectively) than the PedsQL (AUC = .773 and .581, respectively).

CONCLUSION

The Turkish versions of the HEAR-QL-26 child and HEAR-QL-28 adolescent questionnaires are sensitive, reliable, and valid measurement tools to evaluate the hearing-related quality of life in children and adolescents aged between 8 and 18 years.

Prevalence and impact of combined vision and hearing (dual sensory) impairment: A scoping review

Hearing and vision impairments are common globally. They are often considered separately in research, and in planning and delivering services. However, they can occur concurrently, termed dual sensory impairment (DSI). The prevalence and impact of hearing and vision impairment have been well-examined, but there has been much less consideration of DSI. The aim of this scoping review was to determine the nature and extent of the evidence on prevalence and impact of DSI. Three databases were searched: MEDLINE, Embase and Global Health (April 2022). We included primary studies and systematic reviews reporting the prevalence or impact of DSI. No limits were placed on age, publication dates, or country. Only studies where the full text was available in English were included. Two reviewers independently screened titles, abstract, full texts. Data were charted by two reviewers independently using a pre-piloted form. The review identified 183 reports of 153 unique primary studies and 14 review articles. Most evidence came from high-income countries (86% of reports). Prevalence varied across reports, as did age groups of participants and definitions used. The prevalence of DSI increased with age. Impact was examined across three broad groups of outcomes-psychosocial, participation, and physical health. There was a strong trend towards poorer outcomes for people with DSI across all categories compared to people with one or neither impairment, including activities of daily living (worse for people with DSI in 78% of reports) and depression (68%). This scoping review highlights that DSI is a relatively common condition with substantial impact, particularly among older adults. There is a gap in evidence from low and middle-income countries. There is a pressing need for a consensus position on the definition(s) of DSI and standardisation of reporting age groups to enable reliable estimates to be ascertained and compared and responsive services developed.

Subjective Fatigue in Children With Unaided and Aided Unilateral Hearing Loss

OBJECTIVES

Fatigue is frequently observed in children with chronic diseases and can affect the quality of life (QoL). However, research in children with unilateral hearing loss (UHL) is scarce. Subsequently, no studies investigated the effects of hearing aids on fatigue in children. This study investigates subjective fatigue and hearing-related QoL in children with UHL. Furthermore, it evaluates the influence of hearing aids, subject-specific factors, and respondent-type on subjective fatigue.

STUDY DESIGN

A cross-sectional study was conducted from June 2020 until September 2020 at the department of otorhinolaryngology in a tertiary referral center.

METHODS

The primary outcome was the difference in subjective fatigue and hearing-related QoL between children with unaided UHL, aided UHL, and normal hearing. Subjective fatigue and hearing-related QoL were measured using the Pediatric Quality of Life Inventory™ Multidimensional Fatigue Scale (PedsQL™-MFS) and Hearing Environments and Reflection on Quality of Life (HEAR-QL™) questionnaires.

RESULTS

Along with 36 aided children with UHL, 34 unaided and 36 normal-hearing children were included. Child reports revealed significantly more cognitive fatigue in children with aided UHL than children with normal hearing (median difference 12.5, P = .013). Parents reported more fatigue in children with UHL compared to normal-hearing siblings. Especially children with aided UHL seemed at increased risk for fatigue. Children with UHL scored lower on hearing-related QoL than children with normal hearing. No apparent differences were found in fatigue and QoL between children with unaided and aided UHL.

CONCLUSION

Children with unaided and even aided UHL seem to experience more subjective fatigue and lower hearing-related QoL than children with normal hearing. Prospective longitudinal studies are required to investigate the influence of hearing aids on fatigue and QoL in individual patients.

Impact of the Visual Performance Reinforcement Technique on Oral Hygiene Knowledge and Practices, Gingival Health, and Plaque Control in Hearing- and Speech-Impaired Adolescents: A Randomized Controlled Trial

This study aimed to evaluate the impact of oral health education (OHE), incorporating a novel pre-validated visual performance reinforcement (VPR) technique and sign language, on gingival health, plaque control, and oral hygiene knowledge and practices in 12 to 15-year-old hearing- and speech-impaired adolescents. A double-blinded randomized controlled trial was conducted in a government school for deaf children in Belagavi, Karnataka, India. A total of 80 adolescents, aged 12-15 years, were randomly assigned, using a computer-generated table of random numbers, into two groups: Group A receiving the VPR technique (n = 40), and Group B receiving sign language (n = 40). A specially designed pre-validated closed-ended questionnaire was administered to both groups, followed by clinical examination to obtain the gingival and plaque index, before intervention and at a 16-week follow-up period. Group A showed a significant increase in the knowledge gained when compared to Group B. Similarly, a significant improvement in oral hygiene practices was also observed in Group A. However, at the 16-week follow-up, there were no statistically significant differences in gingival and plaque scores between the groups. OHE using the VPR technique can be as effective and satisfactory as sign language in the reduction of gingival and plaque scores and in the improvement of knowledge and its application in oral hygiene maintenance among hearing- and speech-impaired adolescents.

Discrimination and Deaf Adolescents' Subjective Well-Being: The Role of Deaf Identity

This study tested the influence of Deaf identity (cognitive identification and affective identification) on the association between perceived deaf discrimination and subjective well-being among Chinese adolescents who are deaf and hard-of-hearing (DHH), based on the rejection-identification model. Questionnaires on perceived deaf discrimination, subjective well-being, Deaf identity, and demographic information were completed by 246 DHH students (15-23 years old) from special residential schools in China. The results indicated that: (1) higher level of perceived deaf discrimination was significantly associated with lower level of subjective well-being (direct effect = -0.24, 95% confidence interval [CI] = [-0.37, -0.12], p < .001); (2) there was a significant indirect effect of perceived deaf discrimination on subjective well-being via cognitive identification (indirect effect = -0.07, 95% CI = [-0.12, -0.01], p < .05); and (3) positive affective identification due to increased cognitive identification with Deaf community may help counteract the negative impact of perceived deaf discrimination on subjective well-being (indirect effect = 0.06, 95% CI = [0.03, 0.10], p < .001). These findings further support the notion that the different components of group identification should be examined separately.

Hearing-related quality of life assessment of pediatric cochlear implant users with inner ear malformations

OBJECTIVES

To assess the quality of life (QoL) in child and adolescent cochlear implant users with inner ear malformations (IEM) and to compare their outcomes to their cochlear implant using peers with normal inner ear structures.

METHODS

The present sample consisted of 100 children (45 with IEM, 55 without IEM) and 100 adolescents (46 with IEM, 54 without IEM). The following QoL questionnaires were used to assess the hearing-related QoL: The Hearing Environments and Reflection on Quality of Life 26 (HEAR-QL-26 for children between 7 and 12 years of age) and HEAR-QL-28 (for adolescents between 13 and 18 years of age). Both questionnaires were based on a 5-points Likert scale from 0 to 4, with higher scores indicating a better perception of QoL. The scores were converted to percentage values (never = 100, almost never = 75, sometimes = 50, often = 25, almost always = 0).

RESULTS

For the patients with IEM, mean scores from the HEAR-QL-26 and HEAR-QL-28 were 50.4 (SD = 18.9) and 54.5 (SD = 19.6), respectively. For the patients without IEM, mean scores from the HEAR-QL-26 and HEAR-QL-28 were 72.7 (SD = 18.0) and 65.0 (SD = 19.1), respectively. For both child and adolescent subgroups, statistically significant differences were observed between QoL scores from patients with and without IEM (p < 0.001). There were no statistically significant effects of the malformation type on the QoL findings (p ≥ 0.05).

CONCLUSION

Child and adolescent cochlear implant users with IEM had significantly lower scores on validated HEAR-QL versions in comparison to their implanted peers without IEM.

Impact of unilateral hearing loss in early development

PURPOSE OF REVIEW

The purpose of this review is to provide an update on current literature as it relates to the impact of unilateral hearing loss for the pediatric population.

RECENT FINDINGS

Current studies further corroborate past research findings which reveal the potential consequences of unilateral hearing loss on spatial hearing, language, and neurocognitive functioning. Deficits among children with unilateral hearing loss may parallel those seen in children with bilateral hearing loss, further challenging historic views that hearing in one ear in childhood is sufficient for normal development. The potential deficiencies seen in children with unilateral hearing loss can be subtler than those seen with bilateral hearing loss, but may nonetheless also impact school performance, patient fatigue, parental stress, and quality of life. Early interventions within a sensitive period of development of the central auditory system may circumvent potential barriers in cognitive, academic, and psychosocial development.

SUMMARY

This review synthesizes the latest research on the impact of unilateral hearing loss in childhood and the role for possible interventions. The summarized information may serve to support the development of new guidelines for the evaluation and treatment of children with unilateral hearing loss.

Accessing hearing-health services for deaf and hard-of-hearing children during the COVID-19 pandemic: Parent and child perspectives

To describe hearing-health service use, especially use of telehealth, during the early stages of the COVID-19 pandemic in deaf/hard-of-hearing children. In 2020, the Victorian Childhood Hearing Longitudinal Databank surveyed 497 (61.6%) families of deaf/hard-of-hearing children aged 0.4-19.6 years, with 449 (90.3%) providing quantitative data and 336 (67.6%) providing free-text comments about COVID-19's impact on service use and access. We summarised quantitative data using descriptive statistics and analysed free-text responses using inductive and deductive reasoning. Of the 1152 services families used during the pandemic, 711 (62%) were accessed via telehealth. Parents reported several challenges and facilitators of service access during the pandemic, particularly regarding telehealth. Parents reported that their child found telehealth appointments more difficult (347/665, 52.1%) and of worse quality (363/649, 55.9%) compared to in-person. These difficulties were more evident in pre-school than school-age children. Consideration of these factors when implementing telehealth practice beyond the pandemic would improve family experiences, ensuring quality of care.

Mobile health school screening and telemedicine referral to improve access to specialty care in rural Alaska: a cluster- randomised controlled trial

BACKGROUND

School-based programmes, including hearing screening, provide essential preventive services for rural children. However, minimal evidence on screening methodologies, loss to follow-up, and scarcity of specialists for subsequent care compound rural health disparities. We hypothesised telemedicine specialty referral would improve time to follow-up for school hearing screening compared with standard primary care referral.

METHODS

In this cluster-randomised controlled trial conducted in 15 rural Alaskan communities, USA, we randomised communities to telemedicine specialty referral (intervention) or standard primary care referral (control) for school hearing screening. All children (K-12; aged 4-21 years) enrolled in Bering Straight School District were eligible. Community randomisation occurred within four strata using location and school size. Participants were masked to group allocation until screening day, and assessors were masked throughout data collection. Screening occurred annually, and children who screened positive for possible hearing loss or ear disease were monitored for 9 months from the screening date for follow-up. Primary outcome was the time to follow-up after a positive hearing screen; analysis was by intention to treat. The trial was registered with ClinicalTrials.gov, NCT03309553.

FINDINGS

We recruited participants between Oct 10, 2017, and March 28, 2019. 15 communities were randomised: eight (750 children) to telemedicine referral and seven (731 children) to primary care referral. 790 (53·3%) of 1481 children screened positive in at least one study year: 391 (52∤1%) in the telemedicine referral communities and 399 (50∤4%) in the primary care referral communities. Of children referred, 268 (68·5%) in the telemedicine referral communities and 128 (32·1%) in primary care referral communities received follow-up within 9 months. Among children who received follow-up, mean time to follow-up was 41·5 days (SD 55·7) in the telemedicine referral communities and 92·0 days (75·8) in the primary care referral communities (adjusted event-time ratio 17·6 [95% CI 6·8-45·3] for all referred children). There were no adverse events.

INTERPRETATION

Telemedicine specialty referral significantly improved the time to follow-up after hearing screening in Alaska. Telemedicine might apply to other preventive school-based services to improve access to specialty care for rural children.

French adaptation and validation of the Speech, Spatial and Qualities of Hearing scale for Parents (SSQ-P) and for Children (SSQ-Ch)

OBJECTIVES

Hearing loss can seriously impact children's daily life. This study aims to translate and validate the French versions of the hearing performance questionnaires, SSQ-Parent (for 5-18 years old children), and SSQ-Children (for 11-18 years old children).

DESIGN

This controlled prospective trial was conducted between April and October 2020. The forward-backward translation method was used, and a test-retest procedure was carried out on a case and a control population. Cases had at least 30 dBHL hearing loss.

STUDY SAMPLE

54 cases (mean age 10.4 years old) and 32 controls (mean age 12.5 years old) answered the SSQ-Parent. 35 cases (mean age 13.1 years old) and 35 controls (mean age 14.3 years old) answered the SSQ-Children.

RESULTS

Spearman's correlation coefficients between global scores of the test and re-test were 0.91 (p < 0.001) for SSQ-Parent, and 0.89 (p < 0.001) for SSQ-Children. Both tests were discriminant (respectively, global score 57.8 vs 92 p < 0.001, 61.2 vs 92.6 p < 0.001), and internally consistent (Cronbach's alpha 0.94 and 0.97). Items-global score correlation was satisfactory. ROC curves showed high area under curve for the SSQ-Children (0.990), and SSQ-Parent (0.988).

CONCLUSION

The SSQ-Parent and SSQ-Children revealed excellent statistical properties, and can be used for the evaluation of hearing performance of children.

French adaptation and validation of parents' evaluation of aural/oral performance of children (PEACH) scale in children

OBJECTIVE

Hearing loss can seriously impact children's quality of life. Disease-specific questionnaires are required to optimise medical care. This study aims to translate, adapt and validate the French version of the PEACH score for the auditory performance of children.

DESIGN

This is a controlled, prospective study, conducted between April and October 2020. The translation was conducted using a forward-backward technique, and statistical validation was conducted with a test and re-test, on a patient population and a control population.

STUDY SAMPLE

Patients were included if they were 1-11 years old, and had at least 30 dB hearing loss in one ear. The mean age was 6 years for the 39 patients and 3.9 years for the 34 controls.

RESULTS

Reproducibility, measured by Spearman's coefficient between global scores of the test and re-test was 0.78 (p < 0.001). The test was internally consistent (Cronbach's alpha was 0.89) and item per item construct validity was satisfactory. The ROC curve showed a moderate area under the curve (0.74 p < 0.001) with 67% sensitivity and 73% specificity.

CONCLUSIONS

The French PEACH had good statistical properties, although a brief 13-item questionnaire, and can be used for evaluation of the disease-specific quality of life for young children with hearing loss.

Virally Mediated Connexin 26 Expression in Postnatal Scala Media Significantly and Transiently Preserves Hearing in Connexin 30 Null Mice

Non-sensory cells in the sensory epithelium of the cochlea are connected extensively by gap junctions. Functionally null mutations in GJB6 (encoding Cx30) cause hearing loss in humans. In this study, we injected AAV1-CB7-Gjb2 into the scala media between P0-2 in the cochlea of Gjb6^−/− mice. The injection increased Cx26 expression and significantly preserved auditory functions. However, the hearing preservation gradually declined and essentially disappeared 3 months after the injections. In contrast, the morphological preservation was still significant at 3 months post-injection. We found that the expression of Cx26, at both the mRNA and protein levels, showed substantial decreases during the 3-month period. Curiously, treatments by injecting AAV1-CB7-Gjb6 with the identical approach failed to yield any hearing preservation. Our results demonstrated the first successful cochlear gene therapy treatment in mouse models by virally expressing a companion gene of Gjb6.

Early onset adult deafness in the Rhodesian Ridgeback dog is associated with an in-frame deletion in the EPS8L2 gene

Domestic dogs exhibit diverse types of both congenital and non-congenital hearing losses. Rhodesian Ridgebacks can suffer from a progressive hearing loss in the early stage of their life, a condition known as early onset adult deafness (EOAD), where they lose their hearing ability within 1–2 years after birth. In order to investigate the genetic basis of this hereditary hearing disorder, we performed a genome-wide association study (GWAS) by using a sample of 23 affected and 162 control Rhodesian Ridgebacks. We identified a genomic region on canine chromosome 18 (CFA18) that is strongly associated with EOAD, and our subsequent targeted Sanger sequencing analysis identified a 12-bp inframe deletion in EPS8L2 (CFA18:25,868,739–25,868,751 in the UMICH_Zoey_3.1/canFam5 reference genome build). Additional genotyping confirmed a strong association between the 12-bp deletion and EOAD, where all affected dogs were homozygous for the deletion, while none of the control dogs was a deletion homozygote. A segregation pattern of this deletion in a 2-generation nuclear family indicated an autosomal recessive mode of inheritance. Since EPS8L2 plays a critical role in the maintenance and integrity of the inner ear hair cells in humans and other mammals, the inframe deletion found in this study represents a strong candidate causal mutation for EOAD in Rhodesian Ridgebacks. Genetic and clinical similarities between childhood deafness in humans and EOAD in Rhodesian Ridgebacks emphasizes the potential value of this dog breed in translational research in hereditary hearing disorders.

Functional Reorganization of the Central Auditory System in Children with Single-Sided Deafness: A Protocol Using fNIRS

In children, single-sided deafness (SSD) affects the development of linguistic and social skills and can impede educational progress. These difficulties may relate to cortical changes that occur following SSD, such as reduced inter-hemispheric functional asymmetry and maladaptive brain plasticity. To investigate these neuronal changes and their evolution in children, a non-invasive technique is required that is little affected by motion artifacts. Here, we present a research protocol that uses functional near-infrared spectroscopy (fNIRS) to evaluate the reorganization of cortical auditory asymmetry in children with SSD; it also examines how the cortical changes relate to auditory and language skills. The protocol is designed for children whose SSD has not been treated, because hearing restoration can alter both brain reorganization and behavioral performance. We propose a single-center, cross-sectional study that includes 30 children with SSD (congenital or acquired moderate-to-profound deafness) and 30 children with normal hearing (NH), all aged 5–16 years. The children undergo fNIRS during monaural and binaural stimulation, and the pattern of cortical activity is analyzed using measures of the peak amplitude and area under the curve for both oxy- and deoxyhemoglobin. These cortical measures can be compared between the two groups of children, and analyses can be run to determine whether they relate to binaural hearing (speech-in-noise and sound localization), speech perception and production, and quality of life (QoL). The results could be of relevance for developing individualized rehabilitation programs for SSD, which could reduce patients’ difficulties and prevent long-term neurofunctional and clinical consequences.

Prevalence of hearing screening failures in low-risk childhood cancer survivors

BACKGROUND

We sought to estimate the frequency of hearing screening failures in pediatric cancer survivors at low risk for hearing loss and evaluate the feasibility of administering screenings in this population.

PROCEDURE

Survivors in the St. Louis Children's Hospital Late Effects Clinic were recruited. Eligibility included (a) diagnosis of a pediatric cancer treated without platinum chemotherapy or cranial radiation, (b) at least 6 months from completion of therapy, (c) between the ages of 7 and 18 years, (d) cognitively/behaviorally able to participate, and (e) English speaking. Behavioral hearing screenings from 1000 to 8000 Hz were performed by trained personnel using a calibrated audiometer. A failed screen was defined by a participant not responding to two or more of the three screening attempts for at least one frequency in at least one ear.

RESULTS

One hundred nine patients met eligibility criteria with 78 enrolled (71.5%). Diagnoses included leukemia (57.7%), sarcoma (11.5%), Wilms tumor (14.1%), lymphoma (12.8%), and other solid tumors (3.9%). The median age was 13.2 years (Q1-Q3: 9.6-15.4) and the median time from treatment completion was 3.7 years (Q1-Q3: 2.3-7.4). Eighteen patients (23%) failed the hearing screen (95% CI: 14%-34%). No demographic or treatment-related variables were significantly correlated to screening failure. Six screen failures (33%) underwent formal audiology assessments, with three demonstrating unilateral hearing loss: two conductive and one sensorineural.

CONCLUSIONS

A significant fraction of pediatric cancer survivors at low risk for hearing loss failed hearing screening. Broader use of hearing screening should be considered.

Discriminant Validity of the Parent-Proxy Preschool HEAR-QL

OBJECTIVE

The parent-proxy Preschool HEAR-QL (Hearing Environments And Reflections on Quality of Life) is a quality of life (QOL) measure for 2 to 6-year-old children with hearing loss (HL). We compared Preschool HEAR-QL scores for children with HL and children with normal hearing (NH) to examine the measure's discriminant validity.

STUDY DESIGN

Cross-sectional study.

SETTING

Three tertiary care pediatric otolaryngology clinics.

PATIENTS

Two hundred forty-eight parents of children 2 to 6 years old with NH or HL participated.

INTERVENTIONS

None.

MAIN OUTCOME MEASURE

The Preschool HEAR-QL has five domains: Behavior and Attention, Hearing Environments, New Social Situations, Social Interactions, and Communications. Scores range from 0 to 100; higher scores indicate higher QOL. Scores for children with NH and with HL were compared using analysis of variance (ANOVA) and area under the receiver operating characteristic (AUROC) curves.

RESULTS

Total HEAR-QL mean (SD) scores were higher for children with NH compared to children with HL (75.7 [10.5] vs. 67.5 [15.5], p < 0.001). Scores were not significantly different between children with unilateral and bilateral HL. Children 2 to 4 years old received lower Communications-domain scores than children 4 to 6 years old across all children (63.7 [25.4] vs. 74.1 [24.3], p = 0.01) and within the HL cohort (61.3 [25.1] vs. 72.6 [25.3]; p = 0.009). The Hearing Environments domain displayed excellent discrimination (AUROC = 0.858); other domains showed little to no discrimination.

CONCLUSIONS

The Hearing Environments-domain of the Preschool HEAR-QL differentiated between children with and without HL. Children with NH had higher scores than children with HL on both Total HEAR-QL and Hearing Environment-domain scores.

Barriers to access and utilization of healthcare by children with neurological impairments and disability in low-and middle-income countries: a systematic review

Background: Neurological impairments (NI) and disability are common among older children in low-and middle-income countries (LMICs). We conducted a systematic review to examine the barriers limiting access and utilization of biomedical and rehabilitative care by children and adolescents with NI in LMICs.

Methods: We searched PubMed, Latin America and Caribbean Health Sciences Literature, Global Index Medicus, and Google Scholar for studies published between 01/01/1990 and 14/11/2019 to identify relevant studies. We included all studies reporting on barriers limiting access and utilization of preventive, curative, and rehabilitative care for children aged 0-19 years with NI in five domains: epilepsy, and cognitive, auditory, visual, and motor function impairment. Data from primary studies were synthesized using both qualitative and quantitative approaches.

Results: Our literature searches identified 3,258 reports of which 20 were included in the final analysis. Fifteen studies (75.0%) originated from diverse settings in sub-Saharan Africa (SSA). Factors limiting access and utilization of healthcare services in >50% of the studies were: financial constraints (N=17, 85.0%), geographical and physical inaccessibility (N=14, 70.0%), inadequate healthcare resources (N=14, 70.0%), prohibitive culture and beliefs (N=12, 60.0%), and inadequate education/awareness (N=11, 55.0%). Factors reported in <50% of the studies included competing domestic roles (N=4, 20%) and a lack of confidentiality for personal information (N=2, 10.0%). Very few reports were identified from outside Africa preventing a statistical analysis by continent and economic level.

Conclusions: Financial constraints, geographic and physical inaccessibility, and inadequate healthcare resources were the most common barriers limiting access and utilization of healthcare services by children with NI in LMICs.

Social communication and quality of life in children using hearing aids

OBJECTIVES

This study compared the parent-reported structural language and social communication skills-measured with the Children's Communication Checklist-2 (CCC-2)-and health-related quality of life (HR-QOL)-measured with the Pediatric Quality of Life Inventory (PedsQL)-of children who use hearing aids (HAs) and their typical-hearing (TH) peers.

DESIGN

The participants were 88 children (age range of 5; 6 to 13; 1 (years; months)) and their parents: 45 children with bilateral moderate to severe hearing loss using HAs who had no additional disabilities and 43 children with typical hearing. The groups were matched based on chronological age, gender, nonverbal IQ, and parental education level. The parents completed questionnaires related to their children's communication skills, including subdomains structural language and social communication, and HR-QOL.

RESULTS

The HA group had significantly poorer overall communication skills than the TH group (r = 0.49). The children in the HA group scored significantly lower than the TH group on both structural language (r = 0.37) and social communication (r = 0.41). Half of the children in the HA group had overall communication scores that either indicated concern or required further investigation according to the instrument's manual. In terms of psychosocial functioning, which was measured as HR-QOL, the subdomain school functioning was the main driver of the difference between groups, with the HA group being at least twice as likely (OR = 2.52) as the TH group to have poor HR-QOL in the school domain. Better parent-reported social communication was associated with better parent-reported psychosocial functioning in the children using HAs-even when background variables were taken into account.

CONCLUSION

The results suggest that traditional assessments and interventions targeting structural aspects of language may overlook social communication difficulties in children with HAs, even those with no additional disabilities. As school functioning stood out as the most problematic domain for children with HAs, efforts to improve the well-being of these children should focus on this area.

Hearing rehabilitation of children and adolescents with unilateral hearing loss

PURPOSE

To describe the audiological characteristics and the type of intervention chosen on unilateral hearing loss cases in children and adolescents as well as to analyze correlations between the degree of hearing loss, the indication and the use of electronic devices.

METHODS

Observational, descriptive and retrospective study, carried out with information of 34 medical records from children and adolescents with unilateral hearing loss, assessed by two auditory rehabilitation services of medium complexity, throughout 2016 to 2019. Descriptive and Inferential statistical analysis were performed with the data.

RESULTS

A predominance of profound sensorineural unilateral hearing loss in the right ear, of pre-lingual character, with 20.6% of malformations. The most adopted intervention was the hearing aid indication, although its use is low, regardless of the degree of the hearing loss. An association was found between the degree of the hearing loss and the healthcare professionals in indicating the use of the devices.

CONCLUSION

The indication of hearing aids is the most frequent and this decision is influenced by the degree of the hearing loss, in which the devices are mostly indicated for mild to severe losses, with bigger divergence of conduct for profound hearing losses.

Italian Version of the YQOL-DHH Questionnaire: Translation and Cross-cultural Adaptation

Objective

To translate and cross-culturally adapt into Italian the YQOL-DHH (Youth Quality of Life Instrument–Deaf and Hard of Hearing Module), an instrument to evaluate the health-related quality of life in young deaf people. It could be useful for professionals, teachers, and parents to take care of deaf adolescents’ needs.

Study Design

Forward-backward translation, cross-cultural adaptation, and cognitive debriefing.

Setting

The cognitive debriefing was performed online with professionals and during clinical practice with deaf adolescents.

Methods

A methodological study was conducted according to the guidelines provided by the development team. The study consisted of a forward-backward translation and a cross-cultural adaptation. After the original authors’ confirmation, a cognitive debriefing was conducted with 30 professionals who work with deaf young people and with 10 deaf adolescents aged 11 to 18 years.

Results

For the linguistic translation and cross-cultural adaptation, some variations to the original instrument were made to obtain equivalence, such as the expression “deaf or hard of hearing” translated only with the Italian word “sordo.” During the cognitive debriefing, the clarity and comprehensibility of the items were reported by professionals and deaf adolescents. Eventually, the authors approved the final version.

Conclusion

The YQOL-DHH was translated and culturally adapted into Italian. The translated items were pertinent to the Italian culture and equivalent to the original ones. A validation study is suggested to make the instrument feasible for use in different clinical or educational contexts. In addition, to guarantee accessibility and autonomy for young deaf signers, Italian Sign Language translation of the questionnaire is suggested.

Therapeutic effects of stem cells in different body systems, a novel method that is yet to gain trust: A comprehensive review

Stem cell therapy has been used to treat several types of diseases, and it is expected that its therapeutic uses shall increase as novel lines of evidence begin to appear. Furthermore, stem cells have the potential to make new tissues and organs. Thus, some scientists propose that organ transplantation will significantly rely on stem cell technology and organogenesis in the future. Stem cells and its robust potential to differentiate into specific types of cells and regenerate tissues and body organs, have been investigated by numerous clinician scientists and researchers for their therapeutic effects. Degenerative diseases in different organs have been the main target of stem cell therapy. Neurodegenerative diseases such as Alzheimer's, musculoskeletal diseases such as osteoarthritis, congenital cardiovascular diseases, and blood cell diseases such as leukemia are among the health conditions that have benefited from stem cell therapy advancements. One of the most challenging parts of the process of incorporating stem cells into clinical practice is controlling their division and differentiation potentials. Sometimes, their potential for  uncontrolled growth will make these cells tumorigenic. Another caveat in this process is the ability to control the differentiation process. While stem cells can easily differentiate into a wide variety of cells,  a paracrine effect controlled activity, being in an appropriate medium will cause abnormal differentiation leading to treatment failure. In this review, we aim to provide an overview of the therapeutic effects of stem cells in diseases of various organ systems. In order to advance this new treatment to its full potential, researchers should focus on establishing methods to control the differentiation process, while policymakers should take an active role in providing adequate facilities and equipment for these projects. Large population clinical trials are a necessary tool that will help build trust in this method. Moreover, improving social awareness about the advantages and adverse effects of stem cell therapy is required to develop a rational demand in the society, and consequently, healthcare systems should consider established stem cell-based therapeutic methods in their treatment algorithms.

Impact of Oral Health Educational Interventions on Oral Hygiene Status of Children with Hearing Loss: A Randomized Controlled Trial

Introduction

Oral health is considered as one of the essential components of the overall health of every individual. Maintaining oral health is a gradual process that requires commitment. Children who require special care such as hearing impairment experience difficulty in maintaining oral health primarily due to communication difficulties. This study is aimed at using different interventions to evaluate the improvement of oral hygiene in hearing impaired children.

Materials and Methods

Fifty-nine children were recruited in this study that were allocated randomly into each group with twenty children as follows: group 1: pictorial, group 2: video, and group 3: control. Mean plaque and gingival scores were noted before and after the use of different interventions. Oral hygiene was categorized as “excellent,” “good,” and “fair.” Gingival health was categorized as “healthy,” “mild gingivitis,” and “moderate gingivitis.”

Results

Thirty-four children (57.6%) were from 12-13 years of age bracket, and 25 (42.4%) belonged to 14-16 years of age. Regarding gender, there were 37 (62.7%) males and 22 (37.3%) females. About comparison of mean gingival and plaque scores before and after interventions in each group, a significant difference was found in group 1 (p < 0.001) and group 2 (p < 0.001), as compared to group 3 where the difference in scores was not significant (p > 0.05).

Conclusion

Maintaining oral health requires the compliance of individuals to perform different methods of preventive dentistry, such as tooth brushing and use of dental floss. The use of different oral hygiene educational interventions such as pictorial and video methods have been proven and useful for hearing impaired children in improving oral health.

Predicting Quality of Life and Behavior and Emotion from Functional Auditory and Pragmatic Language Abilities in 9-Year-Old Deaf and Hard-of-Hearing Children

Children who are deaf or hard of hearing (DHH) are likely to exhibit difficulties in development of psychosocial skills, pragmatic language skills, and use of hearing for social communication in real-world environments. Some evidence suggests that pragmatic language use affects peer-relationships and school engagement in these children. However, no studies have investigated the influence of functional auditory performance and use of language and speech in real-world environments on children's behavior and emotion, and on their health-related quality of life. This study explored the relationship in DHH children at 9 years of age. Data from 144 participants of the Longitudinal Outcomes of Children with Hearing Impairment study were analyzed. Parent reports were obtained on quality of life, behavior and emotion, pragmatic language skills, and auditory functional performance of children in real life. Children's spoken language abilities and speech intelligibility were assessed by research speech pathologists. On average, performance of children in all domains was within the range of typically developing peers. There were significant associations among functional auditory performance, use of speech and language skills, psychosocial skills, and quality of life. Multiple linear regression analyses revealed that better auditory functional performance and pragmatic language skills, rather than structural language abilities, were associated with better psychosocial abilities and quality of life. The novel findings highlight the importance of targeted intervention for improving functional hearing skills and social communication abilities in DHH children, and emphasize the importance of collaborative approaches among medical, audiology, allied health, and educational professionals to identify those at risk so that timely referral and intervention can be implemented for improving psychosocial health and well-being in DHH children.

Cost-Effectiveness of Screening Preschool Children for Hearing Loss in Australia

OBJECTIVES

While all newborns in Australia are tested for congenital hearing loss through universal newborn hearing screening programs, some children will acquire hearing loss in their first five years of life. Delayed diagnosed or undiagnosed hearing loss in children can have substantial immediate- and long-term consequences. It can significantly reduce school readiness, language and communication development, social and emotional development, and mental health. It can also compromise lifetime educational achievements and employment opportunities and future economic contribution to society through lost productivity. The need for a universal hearing screening program for children entering their first year of primary school has been noted in two separate Australian Government hearing inquiries in the last decade. Sound Scouts is a hearing screening application (app) that tests for hearing loss in children using a tablet or mobile device, supervised by parents at home. It tests for sensorineural or permanent conductive hearing loss and central auditory processing disorder in children. In 2018 the Australian Government funded the roll-out of Sound Scouts to allow up to 600,000 children to test their hearing using Sound Scouts. This study estimated the cost-effectiveness of screening 5-year-old children for hearing loss using Sound Scouts at home, compared with no screening.

DESIGN

A decision-analytic model was developed to estimate the incremental costs and quality-adjusted life years (QALYs) of administering Sound Scouts over a 20-year time horizon. Testing accuracy was based on comparing Sound Scouts test results to clinical test results while other parameters were based on published data. Costs were estimated from the perspective of the Australian health care system. Univariate and probabilistic sensitivity analyses were undertaken.

RESULTS

Sound Scouts is estimated to result in an average incremental cost of A$61.02 and an average incremental increase in QALYs of 0.01. This resulted in an incremental cost-effectiveness ratio of A$5392 per QALY gained, which is likely to be considered cost-effective by Australian decision makers. Screening with Sound Scouts was found to have a 96.2 per cent probability of being cost-effective using a threshold of A$60,000 per QALY gained.

CONCLUSIONS

Using Sound Scouts to screen five-year-old children for hearing loss (at home) is likely to be cost-effective. Screening children using Sound Scouts will result in early identification and intervention in childhood hearing loss, thereby reducing early childhood disadvantage through cumulative gains in quality of life, education, and economic outcomes over their lifetime.

Newborn Hearing Screening and Intervention in Children with Unilateral Hearing Impairment: Clinical Practices in Three Nordic Countries

Studies have limitedly considered children with early-identified unilateral hearing impairment (UHI), and clinical practices regarding screening, diagnostics and habilitation in this group are rarely documented. In this study, routines for newborns with UHI from screening to diagnostics and habilitation were explored in Norway, Sweden and Finland. An online survey was sent to hospitals responsible for the hearing diagnostics of children requesting information about their practices regarding congenital UHI. Responses covered 95% of the children born in the three included countries. The results revealed large variations in ways of organising healthcare and in clinical decisions regarding hearing screening, diagnostics and habilitation of children with congenital UHI. Finally, implications for policy making and research are also discussed.

Quality of life of children treated for unilateral hearing loss: a systematic review and meta-analysis

OBJECTIVE

To evaluate the treatments' consequences for unilateral hearing loss in children.

DESIGN

Systematic review and meta-analysis (CRD42018109417). The MEDLINE, CENTRAL, ISRCTN and ClinicalTrials databases were searched between September 2018 and May 2019. Articles were screened and data were collected independently by two authors following the Cochrane and Preferred Reporting Items for Systematic review and Meta-Analysis guidelines. The risk of bias was evaluated using the Cochrane tool, the Newcastle-Ottawa Scale, the National Institute of Health, USA tool and considering the risk of confounding. In the studies with the lowest risk of bias, a meta-analysis was conducted.

INTERVENTIONS

Validated hearing rehabilitation devices.

PATIENTS

6-15 years old children with moderate to profound unilateral hearing loss.

MAIN OUTCOME MEASURES

The primary study outcome was children's quality of life. Academic performances were studied as an additional outcome.

RESULTS

731 unique articles were identified from the primary search. Of these, 18 articles met the Population, Intervention, Control, Outcomes and Study design selection criteria. In the eight studies with the lowest risk of bias, two meta-analysis were conducted. There was not enough data on academic results to conduct a meta-analysis. In 73 children included in a fixed effect meta-analysis (two studies), no effect of treatment could be shown (g=-0.20, p=0.39). In 61 children included in a random-effect meta-analysis (six studies), a strong positive effect of hearing treatment on quality of life was demonstrated (g=1.32, p<0.05).

CONCLUSIONS

The treatment of unilateral hearing loss seems to improve children's quality of life. Further research is needed to identify the most effective treatment and its corresponding indications.

A systematic scoping review of early interventions for parents of deaf infants

Background

Over 90% of the 50,000 deaf children in the UK have hearing parents, many of whom were not expecting a deaf child and may require specialist support. Deaf children can experience poorer long-term outcomes than hearing children across a range of domains. After early detection by the Universal Newborn Hearing Screening Programme, parents in the UK receive support from Qualified Teachers of the Deaf and audiologists but resources are tight and intervention support can vary by locality. There are challenges faced due to a lack of clarity around what specific parenting support interventions are most helpful.

Methods

The aim of this research was to complete a systematic scoping review of the evidence to identify early support interventions for parents of deaf infants. From 5577 identified records, 54 met inclusion criteria. Two reviewers screened papers through three rounds before completing data extraction and quality assessment.

Results

Identified parent support interventions included both group and individual sessions in various settings (including online). They were led by a range of professionals and targeted various outcomes. Internationally there were only five randomised controlled trials. Other designs included non-randomised comparison groups, pre / post and other designs e.g. longitudinal, qualitative and case studies. Quality assessment showed few high quality studies with most having some concerns over risk of bias.

Conclusion

Interventions commonly focused on infant language and communication followed by parental knowledge and skills; parent wellbeing and empowerment; and parent/child relationship. There were no interventions that focused specifically on parent support to understand or nurture child socio-emotional development despite this being a well-established area of poor outcome for deaf children. There were few UK studies and research generally was not of high quality. Many studies were not recent and so not in the context of recent healthcare advances. Further research in this area is urgently needed to help develop evidence based early interventions.
