NCT ID: NCT06051968 Enrolling by invitation - Hearing Loss Clinical Trials

Effects of an Online Hearing Support for First-time Hearing Aid Users

Start date: September 18, 2023
Phase: N/A
Study type: Interventional

The goal of this randomised controlled trial is to test a online hearing support for first-time hearing aid users. The main questions it aims to answer are short- and long-term effects on the emotional and social consequences of hearing loss that the participants experience, use of communications strategies, experienced listening in complex sound environments and perceived effectiveness and satisfaction with hearing aids.

NCT ID: NCT05859568 Enrolling by invitation - Hearing Loss Clinical Trials

Baseline Performance and Fitting Parameters for Sonova Products

Start date: April 17, 2023
Phase: N/A
Study type: Interventional

The purpose of this study is to assess the effectiveness and optimization of various FDA approved products.

NCT ID: NCT05245799 Enrolling by invitation - Hearing Loss Clinical Trials

Hear Me Read 2021 Clinical Trial

Start date: March 25, 2022
Phase: N/A
Study type: Interventional

The purpose of this study is to evaluate if the effects of in-person speech-language therapy with a novel digital storybook intervention platform (Hear Me Read) improves vocabulary, speech and language, and literacy outcomes in young children who are deaf or hard of hearing compared with in-person therapy alone.

Motivational Interviewing in Hearing Aid Users

MI-HAT
Start date: March 16, 2021
Phase: N/A
Study type: Interventional

Hearing loss is one of the most common chronic disabilities in the older adult population and affects their quality of life. Hearing aid use can improve one's quality of life by increasing a person's ability to detect, differentiate and locate sound, and improve speech recognition. Several factors seem to reduce motivation to use a hearing aid. Fears of exclusion and shame due to hearing loss are major deterrents to hearing aid use. Motivational interviewing (MI) is a counselling style aimed at creating desire in patients to change their behavior. There have been pilot studies that suggest one-on-one MI can increase hearing aid use, but other pilot studies found the reverse hence the evidence is inconclusive. The effectiveness of group MI therapy is also being investigated in MI research. While results in group MI research are promising, studies investigating group MI have been limited to substance abuse.

Genetic Analyses of Nonsyndromic and Syndromic Deafness in Pakistan

Start date: March 16, 2000
Phase:
Study type: Observational

Objective: One objective of this study is to genetically map and identify mutated genes for human hereditary hearing loss. A second objective is to study the function of these genes in the auditory system using mouse models. Human hereditary hearing impairment is the result of abnormal ear development, abnormal ear function or both. Although the genes for numerous deafness loci have been mapped and identified, there are still many families segregating deafness as a monogenic trait but a mutant allele can t be ascribed to one of the currently reported deafness genes . In order to map and identify novel mutated genes associated with hearing loss in humans, we will continue to ascertain large families segregating syndromic and nonsyndromic deafness as a monogenic trait. Study population: This study will ascertain subjects from consanguineous Pakistani families segregating hearing loss consisting of both nonsyndromic and syndromic forms of deafness of genetic etiology. Since a majority of Pakistani marriages are between first cousins, this tends to bring together the same recessive mutations for hearing loss with multiple affected individuals within single family lines, which is an advantage for this genetic study. A few years ago we stopped ascertaining families in India. We continue to ascertain both affected and unaffected Pakistani family members from age 2 years and up. Adults provide informed consent both for themselves and their children who agree to participate in this study. We will ascertain both genders and all Pakistani races and ethnicities. Design: Subjects will be screened and consented by our collaborating Associate Investigator in Pakistan. After consenting, the subjects will undergo a history and physical, audiological assessment and testing, vestibular assessment and testing, and blood and urine analysis tests, along with a blood sample or buccal swab sample that will be used for genomic DNA extraction. Probands at the time of ascertainment are initially assumed to have a form of nonsyndromic deafness. Additional tests may be performed depending on the history or physical of the individual or after the deafness gene is identified. Data from functional studies in animal models may also point to other concomitant clinical features along with hearing loss. These additional tests may include: photographs or videotapes of a subject s body and face; eye and vision examinations for those with suspected or known eyesight problems related to their genetic hearing loss mutations, and EKGs and/or Echocardiograms for those with suspected or known heart problems related to their genetic hearing loss mutations. Urine and blood analyses may be requested for those individuals with genetic nephritic issues or infertility. For example, when a deaf female individual in a family is subsequently discovered to have Perrault syndrome, a recessive disorder characterized by hearing loss (usually the initial manifestation) and ovarian dysgenesis/primary amenorrhea, additional evaluations would then be conducted for a definitive diagnosis of Perrault syndrome. Such an evaluation would include a pelvic ultrasound scan and measurements of serum estrogen and gonadotropins. Similarly, in some of these families, hearing impaired males may be asked about their fertility since the possibility of male infertility in families segregating Perrault syndrome remains an open question. For genetic analyses, genomic DNA extracted from a blood sample or a buccal swab from affected and unaffected members of families segregating hereditary hearing loss will be genetically screened with polymorphic markers (STRs or SNPs) for linkage to the known deafness loci. The hearing phenotype of children (>2 years old), adolescent and adult subjects will be assigned on the basis of performance from audiological examinations. Genomic DNA from families where deafness is found to be unlinked to the known deafness loci will then be used in genome wide screens with approximately 950,000 SNP markers distributed across the entire human genome to identify novel deafness loci. Alternatively, DNA samples from affected and unaffected individuals will undergo whole exome sequencing (WES) or whole genome sequencing (WGS) with a focus on potentially pathogenic variants located only in chromosomal regions of markers genetically linked to deafness. Subsequently, novel deafness genes will be positionally identified and their functions studied. Outcome measures: Novel deafness loci and genes associated with hearing loss will be identified and will provide new insight into mechanisms required for sound transduction in humans. Data from this study is likely to be the basis of commercially available tests for early diagnosis and timely genetic counseling for at risk couples as well as the development of strategies to preserve hearing and prevent hearing loss.
