Variables influencing executive functioning in preschool hearing-impaired children implanted within 24 months of age: an observational cohort study

A Virtual Reality Platform for Evaluating Deficits in Executive Functions in Deaf and Hard of Hearing Children-Relation to Daily Function and to Quality of Life

Background: Childhood hearing loss is a common chronic condition that may have a broad impact on children's communication and motor and cognitive development, resulting in functional challenges and decreased quality of life (QoL). Objectives: This pilot study aimed to compare executive functions (EFs) as expressed in daily life and QoL between deaf and hard-of-hearing (D/HH) children and children with typical hearing. Furthermore, we examined the relationship between EFs and QoL in D/HH children. Methods: The participants were 76 children aged 7-11 yr: 38 D/HH and 38 with typical hearing. Parents completed the Behavior Rating Inventory of Executive Function (BRIEF) and Pediatric Quality of Life Inventory (PedsQL), while the child performed a shopping task in the virtual action planning supermarket (VAP-S) to reflect the use of EFs in daily activity. Results: D/HH children showed significantly poorer EFs (as measured by BRIEF and VAP-S) and reduced QoL. Difficulties in EFs were correlated with lower QoL. BRIEF scores were significant predictors of QoL domains. Conclusions: Difficulties in EFs may characterize children with D/HH and reduce their QoL. Therefore, EFs should be screened and treated. VAP-S and BRIEF are feasible tools for evaluating EFs that reflect children's challenges due to EF difficulties in real-life contexts.

An Evaluation of Language Development and Working Memory in Children with Hearing Loss

BACKGROUND

 Children with hearing loss (HL) have difficulty in performing the complex functions of language, especially in noisy environments. Cognitive processes such as working memory and short-term memory are effective on individual differences in language skills in children with HL.

PURPOSE

 The present study aimed to evaluate the vocabulary and syntax skills in language development areas and working memory of children with HL and to compare these results with those of their peers with normal hearing (NH).

RESEARCH DESIGN

 In this study, a causal-comparative research model was used to measure vocabulary and syntax skills, which are among the working memory and language development skills of children with NH and those with HL.

STUDY SAMPLE

 A total of 88 children, 44 children with HL aged 60 to 107 (months) and age- and gender-matched 44 children with NH, were included in the study.

INTERVENTION

 Evaluation was made in two sessions of 20 minutes for each participant.

DATA COLLECTION AND ANALYSIS

 The language development and working memory of 44 children with HL and 44 children with NH were evaluated and the two groups were compared with each other. The Working Memory Scale (WMS) was used to evaluate the working memory of the participants and three subtests (vocabulary, sentence repetition, and sentence comprehension) of the Test of Language Development-Primary Fourth Edition: Turkish Version (TOLD-P:4) were used to evaluate language development. SPSS 23.0 program was used in the analysis of the data.

RESULTS

 Children with HL obtained lower scores than their peers with NH in all three TOLD-P subtests. Children with HL obtained significantly lower scores in WMS verbal memory and general WMS scores compared with NH children. A positive correlation was found between WMS Verbal Memory Scores and TOLD-P sentence comprehension and sentence repetition scores. WMS Visual Memory Scores predicted the group with HL and all TOLD-P scores and Verbal Memory Scores predicted the group with NH.

CONCLUSION

 Working memory skills are the predictor of language comprehension, reasoning, learning, literacy skills, and language development. Thus, including working memory skills as well as language skills in the education programs of children with HL contributes to the children's development.

Emotional abilities in preadolescents and adolescents with long-term cochlear implant use

OBJECTIVES

Emotional abilities (EAs) are particularly important during preadolescence/adolescence, two challenging periods characterized by significant biological, physical, and cognitive changes. The present study attempted to a holistic EA approach in preadolescents/adolescents with cochlear implants (CI) and typical hearing (TH), considering various aspects such as perception, cognitive facilitation, comprehension, and management of emotions. A secondary aim was to identify significant demographic and audiological factors of EA development.

METHODS

CI/TH groups were matched for chronological age, nonverbal IQ, gender, economic income, and maternal level of education. Each group consisted of 43 participants (age range 10-18 years). EAs were evaluated by using the multi-trait/method IE-ACCME test. Auditory-linguistic assessments included participants' lexical skills and Matrix performance as well.

RESULTS

EA performance for perception and cognitive facilitation did not show any statistically significant CI/TH group differences (p > 0.05). Significant CI/TH differences emerged for emotion comprehension and management: CI group performed significantly worse in understanding emotional blends (t = 2.56, p = 0.014) but better in personal emotion management (t = -2.01, p = 0.048). For the CI group, gender showed statistically significant effects on cognitive facilitation in sensations, with males performing better than females (U = 129, p = 0.018). TH preadolescents showed significantly lower scores in understanding emotional changes in comparison to TH adolescents (U = 125.5, p = 0.01). Emotional blends understanding showed a weak negative correlation with Matrix performance (r = - 0.38, p = 0.013) and a moderate positive correlation with lexical skills (r = 0.40, p = 0.008). Relationships management showed various significant correlations: weak negative correlations with age at CI (r = - 0.38, p = 0.011) and Matrix performance (r = - 0.36, p = 0.016) as well as weak positive correlations with nonverbal-IQ (r = 0.38, p = 0.013) and positive moderate correlations with lexical skills (r = 0.49, p < 0.001).

CONCLUSION

Cochlear implantation seems to show significant positive effects on emotional development in children, allowing them to achieve age appropriate EAs as they grow up and become preadolescents/adolescents. EA assessment in CI users may not only support monitorization of EA trajectory, but also early identification of any EA disorders, so that subjects with low EA profiles could be timely and properly intervened.

Feasibility and Effectiveness of Speech Intervention Implemented with a Virtual Reality System in Children with Developmental Language Disorders: A Pilot Randomized Control Trial

Language disorders are characterized by impairments in verbal expression/understanding, including difficulties with one or more language components. The Virtual Reality Rehabilitation System (VRRS) is a bioelectromedical device equipped with exercise sections aimed at improving cognitive and language deficits. It also increases patient motivation and engagement. The aim of our study was to test the feasibility and efficacy of VRRS intervention to improve speech therapy treatment for children with speech disorders. Thirty-two patients were enrolled in this study and randomly assigned to the experimental (EG) or control group (CG). The CG underwent conventional speech therapy, while EG underwent VRRS-implemented speech therapy. Both groups were evaluated before (T0) and after (T1) the intervention using the Language Assessment Test. The results showed improvements in both groups. However, the EG group showed greater improvement in various areas, including comprehension of total words, repetition, naming of body parts, naming of everyday objects, total naming, morphosyntactic accuracy, sentence construction, average length of utterance, and spontaneous word production. This study demonstrated that VRRS can be a valuable tool for implementing effective speech rehabilitation. Further studies are needed, as the use of VRRS is still in its early stages, requiring larger samples sizes and long-term follow-up.

Sociodemographic disparities in pediatric cochlear implantation outcomes: A systematic review

OBJECTIVES

To determine the impact of sociodemographic factors on post-operative performance outcomes among PCI recipients across the world.

METHODS

A qualitative systematic review of PubMed, Scopus, Web of Science, and Embase was undertaken for studies analyzing the association of sociodemographic factors with measures of PCI outcomes published before July 18, 2021. Study quality assessment tools from the National Institutes of Health (NIH) were used to assess for risk of bias.

RESULTS

Out of 887 unique abstracts initially retrieved, 45 papers were included in the final qualitative systematic review. Sociodemographic disparities in PCI outcomes from 4702 PCI recipients were studied in 19 countries, with 14 studies conducted in the United States of America, published within the years of 1999 to 2021. Parental education and socioeconomic status (e.g. income) were the most investigated disparities in PCI outcomes with 24 and 17 identified studies, respectively.

CONCLUSION

Socioeconomic status was a consistently reported determinant of PCI outcomes in the USA and elsewhere, and parental education, the most reported disparity, consistently impacted outcomes in countries outside the USA. This study is limited by our inability to perform a meta-analysis given the lack of standardization across measures of sociodemographic variables and assessment measures for PCI outcomes. Future studies should address the literature gap on racial and ethnic disparities among PCI outcomes and use standardized measures for sociodemographic variables and PCI outcomes to facilitate meta-analyses on the topic. Targeting the mechanisms of these disparities may mitigate the impact of the sociodemographic factors on PCI outcomes.

Differential At-Risk Pediatric Outcomes of Parental Sensitivity Based on Hearing Status

Purpose The aim of this study was to investigate the role of parental sensitivity in language and neurocognitive outcomes in children who are deaf and/or hard of hearing (DHH). Method Sixty-two parent-child dyads of children with normal hearing (NH) and 64 of children who are DHH (3-8 years) completed parent and child measures of inhibitory control/executive functioning and child measures of sentence comprehension and vocabulary. The dyads also participated in a video-recorded, free-play interaction that was coded for parental sensitivity. Results There was no evidence of associations between parental sensitivity and inhibitory control or receptive language in children with NH. In contrast, parental sensitivity was related to children's inhibitory control and all language measures in children who are DHH. Moreover, inhibitory control significantly mediated the association between parental sensitivity and child language on the Clinical Evaluation of Language Fundamentals-Fifth Edition Following Directions subscale (6-8 years)/Clinical Evaluation of Language Fundamentals Preschool-Second Edition Concepts and Following Directions subscale (3-5 years). Follow-up analyses comparing subgroups of children who used hearing aids (n = 29) or cochlear implants (CIs; n = 35) revealed similar correlational trends, with the exception that parental sensitivity showed little relation to inhibitory control in the group of CI users. Conclusions Parental sensitivity is associated with at-risk language outcomes and disturbances in inhibitory control in young children who are DHH. Compared to children with NH, children who are DHH may be more sensitive to parental behaviors and their effects on emerging inhibitory control and spoken language. Specifically, inhibitory control, when scaffolded by positive parental behaviors, may be critically important for robust language development in children who are DHH.

Early pediatric Cochlear implantation: An update

The criteria and candidacy for pediatric cochlear implantation (CI) has significantly transformed over the past few decades and continues to evolve with technological advancements, and recognition of benefit in more diverse populations. Prolonged auditory deprivation among patients with profound sensorineural hearing loss has been shown to cause widespread degeneration in the central auditory system. Thus, there is increasing evidence advocating for earlier implantation within a critical neuroplastic window. However, there is a lack of consensus on this optimal age of implantation. Historically, there were concerns regarding surgical feasibility and safety, anesthesia risk, and logistical considerations in very young infants <12 months. Recent literature has investigated surgical safety and anesthesia risk as well speech and language outcomes with early implantation, resulting in the long-awaited reduction in approved age by the FDA (<9 months for certain devices). This article reviews logistical considerations, surgical safety, anesthesia risk, and language developmental outcomes associated with early CI (<12 months).
