Filter by:The goal of this clinical trial is to learn about the different dose regimens of the efficacy of oral steroids in the acute tinnitus population. Participants will receive different appropriate dosages of prednisone tablets and oral Ginkgo Biloba tablets.
This study investigates a newly developed test, The CochSyn test that can quantify cochlear synaptopathy (CS) (a new type of sensorineural hearing loss (SNHL)) earlier than the current golden standard pure-tone audiogram.This newly developed test is based on auditory evoked brain potentials. A hardware prototype (the Cochsyn test prototype) was developed to use the Cochsyn test in clinical practice. Additionally a CS-based sound-processing algorithm (CoNNear) that is designed to improve speech intelligibility in subjects that are identified to have CS, will be investigated in this study.
Prospective, non-randomized, open-label study to evaluate the safety and efficacy of the iotaSOFT Insertion System when used to assist electrode array insertion during cochlear implant surgery in a pediatric population.
The goal of this National Registry is to is to collect information from patients with rare kidney diseases, so that it that can be used for research. The purpose of this research is to: - Develop Clinical Guidelines for specific rare kidney diseases. These are written recommendations on how to diagnose and treat a medical condition. - Audit treatments and outcomes. An audit makes checks to see if what should be done is being done and asks if it could be done better. - Further the development of future treatments. Participants will be invited to participate on clinical trials and other studies. The registry has the capacity to feedback relevant information to patients and in conjunction with Patient Knows Best (Home - Patients Know Best), allows patients to provide information themselves, including their own reported quality of life and outcome measures.
Children who are deaf or hard-of-hearing (D/HH) are at risk of speech and language delays, which can be mitigated through early identification and intervention. Identifying hearing loss (HL) during preschool is crucial, but the most effective hearing screening method for preschoolers remains uncertain. The purpose of this study is to learn whether, compared to the gold-standard two-stage Pure-tone audiometry (PTA) + otoacoustic emissions (OAE) screening (TS-PO), single-stage OAE (SS-O) screening alone is not inferior at identifying hearing loss when performed in a community-based preschool setting. This study holds the potential to improve early hearing loss detection and intervention among D/HH children, reducing the likelihood of speech and language delays. A diverse group of 28,000 preschool-age children across community-based preschool centers will be recruited. The intervention involves all subjects undergoing both PTA and OAE screening, with the order determined through randomization. Children who show potential hearing issues based on screening results or teacher concerns will receive further testing to determine the final hearing outcome. Group allocation will be post-hoc, based on their screening results. In addition to the primary objective, the study will compare other hearing screening measures and outcomes between the two methods (TS-PO and SS-O). This approach aims to reflect the real-life effectiveness of hearing screening in a diverse population. Ultimately, the study seeks to provide insights into an optimal hearing screening method that could prevent speech and language delays among D/HH children.
Sensorineural hearing loss (SNHL) is among the most prevalent chronic conditions in aging and has a profoundly negative effect on speech comprehension, leading to increased social isolation, reduced quality of life, and increased risk for the development of dementia in older adulthood. Typical audiological tests and interventions, which focus on measuring and restoring audibility, do not explain the full range of cognitive difficulties that adults with hearing loss experience in speech comprehension. For example, adults with SNHL have to work disproportionally harder to decode acoustically degraded speech. That additional effort is thought to diminish shared executive and attentional resources for higher-level language processes, impacting subsequent comprehension and memory, even when speech is completely intelligible. This phenomenon has been referred to as listening effort (LE). There is a growing understanding that these cognitive factors are a critical and often "hidden effect" of hearing loss. At the same time, the effects of LE on the neural mechanisms of language processing and memory in SNHL are currently not well understood. In order to develop evidence-based assessments and interventions to improve comprehension and memory in SNHL, it is critical that we elucidate the cognitive and neural mechanisms of LE and its consequences for speech comprehension. In this project, we adopt a multi-method approach, combining methods from clinical audiology, psycholinguistics, and cognitive neuroscience to address this gap of knowledge. Specifically, we adopt a novel and innovative method of co-registering pupillometry (a reliable physiological measure of LE) and language-related event-related brain potential (ERP) measures during real-time speech processing to characterize the effects of clear speech (i.e., a listener-oriented speaking style that is spontaneously adopted to improve intelligibility when speakers are aware of a perception difficulty on behalf of the listener) on high-level language processes (e.g., semantic retrieval, syntactic integration) and subsequent speech memory in older adults with SNHL. This innovative work addresses a time-sensitive gap in the literature regarding the identification of objective and reliable markers of specific neurocognitive processes impacted by speech clarity and LE in age-related SNHL.
Steroids are used widely for the treatment of Sensorineural hearing loss worldwide. The difficulty lies with efficient delivery of the drug into the cochlea, which is already a sealed chamber with limited blood supply that too with an end Artery. We intend to extrapolate its effects by combining it with Platelet rich plasma. intra-tympanic delivery is achieved with injection via tympanic membrane and its absorption via round window is hastened by posture maintenance for about half an hour. PRP is an autologous biologic fluid which has excellent safety profile and is already in use by various specialties.
The study will follow a cohort of CI-candidates becoming CI-user, till two years postoperative. A through-out assessment of both their audiological and vestibular status will be carried out at multiple fixed timepoints over 2 years, evaluating both subjective (patients reported) and objective outcomes over time. For the audiological part of the study both pure-tone and speech audiometry results will be held against the patient perceived benefit of the treatment as assessed by the questionnaires NCIQ and SSQ-12. The vestibular part of the study will evaluate the function of the SCCs and the sacculus. This is will be put in concert with functional tests of the vestibular system, and the patient perceived outcome measure DHI. Correlations between vestibular and audiological performances will be examined. A collection of specific hypotheses will be tested by predefined statistical methods.
The cochlear implant provides good auditory performance despite high inter-individual variability, but performance in noise remains limited. Modification of the coding strategies could improve these performances. A better characterization of the remaining neuronal population by looking for the charge integration efficiency (which depends on the duration and the amplitude of the electrical pulse) would allow an optimization of the settings by adapting either the duration or the amplitude of the pulse according to the quality of the remaining neuronal population.
Individuals with Auditory Neuropathy Spectrum Disorders (ANSD) represent 1-10% of adults with hearing loss. These individuals have little or no benefit from current hearing aids because ANSD is a continuum of hearing impairments due to synaptic or neural dysfunction in the peripheral and central parts of the auditory pathways, which impairs temporal information processing without necessarily affecting auditory sensitivity. There is a need to find ad-hoc denoising methods, based on the expert knowledge of audiologists, to improve the noise comprehension performance of these patients. Implemented denoising methods, based on artificial intelligence, will also greatly benefit more standard hearing loss cases.
