The constant need to listen attentively leads to heightened frustration, fatigue, and decreased concentration. According to research, high-frequency hearing loss could have negative implications on speech perception and make it even harder to communicate. In this study, the focus is on patients with DFNA9 as it is one of the most common forms of non-syndromic high-frequency hearing loss. These patients carry the p.Pro51Ser variant in the COCH gene, which leads to progressive decline of hearing and vestibular function. Despite various cross-sectional studies on the natural progression of hearing levels, speech perception in silence and noisy surroundings is largely unexplored in this group of patients.</p><p><strong>Method: </strong>For the longitudinal analysis of speech perception, 101 heterozygous carriers of the p.Pro51Ser variant in the COCH gene were enrolled. In addition, a control group composed of individuals with normal hearing, who matched the patients with DFNA9 in the study in terms of age and sex, was recruited.

Differences between carriers and control participants seem evident in the third decade of life and become more pronounced in the decades that follow. The SPIN displayed a similar trend, varying from -5 dB SNR in the youngest age-group, to no speech-in-noise thresholds in patients above the age of 60 years. In contrast, the matched group exhibited a SRT range from -5.5 to -3.25 dB SNR for males, and from -6.23 to -4.58 dB SNR for females from the second/third to the seventh decade.

Previous studies have identified Cometin - also known as Meteorin-like - to be neuroprotective and beneficial for metabolic disorders. The aim of our study was to investigate the effects of different concentrations of recombinant human Cometin (hCometin) on SGN in regard to neuroprotection and neurite outgrowth and to evaluate its neurite guidance potential using a neurite outgrowth chamber.</p><p><strong>Methods: </strong>hCometin was initially tested in two separate dosing experiments: 5, 10, and 15 μg/mL (medium dose group) and 10, 25, and 50 μg/mL (high dose group).

The number, morphology, and neurite length of SGN treated with hCometin were compared to untreated (negative control, NC) and brain-derived neurotrophic factor treated (BDNF, 50 ng/mL) (positive control, PC) cells. Subsequently, to investigate a potential effect on neurite guidance, 10 μg/mL hCometin was delivered via osmotic pumps to neonatal murine spiral ganglion explants (SGE) cultured in a neurite outgrowth chamber to experimentally mimic the scala tympani and the Rosenthal's canal.

The medium dose concentrations significantly increased the number of monopolar neurons compared to NC, and 10 and 15 μg/mL hCometin increased the number of neurons with a physiological bipolar morphology to an even greater extent than BDNF. For neurite length, 5 and 10 μg/mL hCometin had the greatest effect, which was comparable with the BDNF-PC.

While this general lag in skill development was no longer observed in the lower grades of elementary school, the upper-grade school children presented lower scores than their hearing peers, although only those pertaining to everyday and social life skills were statistically significant. Accordingly, the average scores were distributed in an inverted V shape among age groups.</p><p><strong>Conclusion: </strong>These results suggest that children who receive CIs at a later age develop their social skills later than their peers with normal hearing in preschool, catch up to their peers in the 1st to 3rd grades, and then lag in the 4th to 6th grades. Accordingly, acquiring age-appropriate social skills in the upper grades remains a challenge for children who obtained CIs at the age of approximately 3, suggesting the need for intervention programs for school-age children even when they do not show significant language acquisition delays.</p>","PeriodicalId":55432,"journal":{"name":"Audiology and Neuro-Otology","volume":" ","pages":"282-293"},"PeriodicalIF":1.6,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143030104","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
