Age Related Hearing Loss

This study aims to assess the effectiveness of a Community Health Worker (CHW) delivered hearing loss intervention program (HEARS) for older adults in Maryland in collaboration with community organizations.

Phase 2a: Multiple Ascending Dose (MAD) in male and female patients with hearing loss: The study will be conducted according to a randomised, placebo-controlled, double-blind design. A total of 24 patients, otherwise healthy, aged up to 75 years old, with mild to moderate hearing loss will be included. Two cohorts of 12 male or female patients (no ratio is required) will receive two different flat doses (low dose and high dose) ofDX243 or placebo for 29 days using SC administration. In each cohort of 12 patients, 4 will be randomised to placebo and 8 to DX243, so at the end of Phase 2a, 8 patients will have received placebo, 8 the low dose and 8 the high dose of DX243. The primary objective is to evaluate the safety and tolerability of DX243 administered subcutaneously after repeated doses. The secondary objectives are to detect preliminary signal of efficacy, using speech in noise tests, tonal and vocal audiometry, as well as tinnitus and quality of life.

This study aims to develop a predictive model for age-related hearing loss (ARHL) based on multi-source risk factors and artificial intelligence techniques. A retrospective analysis will be conducted on 1,000 cases with 15-year longitudinal clinical data, including audiological assessments and noise exposure history. Machine learning algorithms will be employed to construct a predictive model for hearing loss progression. Additionally, a prospective cohort of 100 community-dwelling elderly individuals will be enrolled. Blood samples will be collected for low-abundance targeted proteomics analysis to screen for biomarkers associated with cognitive impairment. This study will establish an early risk identification tool for ARHL and propose strategies for the screening and prevention of dementia in individuals with hearing impairment, thereby providing evidence-based support for early intervention in auditory and cognitive health in the elderly.

Against the backdrop of global population aging, age-related hearing loss (ARHL) has reached epidemic proportions and is increasingly recognized as an independent risk factor for cognitive decline and other major neurodegenerative diseases. This study aims to systematically develop an integrated framework for the early warning, precise assessment, and intervention management of ARHL. Using a national multicenter design, the project will establish a prospective cohort of more than 3,000 older adults. We will integrate multimodal data including audiological tests, cognitive function assessments, and blood biomarkers, and employ artificial intelligence and unsupervised machine learning methods to address critical bottlenecks in the field: the unclear mechanistic link between ARHL and cognitive decline, and the lack of validated predictive tools. Specifically, this study will: (1) develop data-driven clinical classification criteria for ARHL; (2) create a personalized "Hearing Health Clock" predictive model; (3) identify minimally invasive blood biomarkers for early detection of cognitive impairment; and (4) formulate a multidimensional early dementia screening program suitable for community-wide implementation. The findings will provide scientific evidence and practical tools for the prevention and control of hearing and cognitive health risks in older adults in China.

This study compares the hearing improvement effects of domestic hearing aids and imported hearing aids in 80 patients with moderate to severe and severe age-related hearing loss. Patients will be randomly assigned to either the experimental group (domestic hearing aids) or the control group (imported hearing aids) and will undergo a 30-minute trial. Pure Tone Average (PTA) and Speech Recognition Threshold (SRT) will be measured both before and after the trial. The improvements in PTA and SRT will be calculated.The market prices of the hearing aids and the degree of hearing improvement in decibels will be recorded. These data will be used to conduct a comprehensive cost-effectiveness analysis. After the trial, the International Outcome Inventory for Hearing Aids (IOI-HA) and the Abbreviated Profile of Hearing Aid Benefit (APHAB) will be used to assess the benefits of the hearing aids.

The purpose of this study is to explore the safety and efficacy of TJ0113 capsules in patients with age-related hearing loss.

Objectives To assess the feasibility and acceptability of using a home-based, social robot-assisted intervention (SRAI) for older adults with hearing loss (HL), and to examine the preliminary effects of SRAI on improving physical activity, loneliness, communication, and health-related quality of life in this population. Hypothesis to be tested SRAI is feasible for implementation at home and acceptable to participants. Upon completing the 10-week intervention and the 1-month follow-up, the intervention group (IG) will report significantly greater improvements in measured outcomes. These findings will support subsequent investigations in a larger-scale randomized controlled trial (RCT). Design and subjects A two-arm, single-blinded, pilot RCT with individual semi-structured interviews. Chinese adults aged 65 years or older, with mild-to-moderate HL with a pure-tone average of 20-50 dB across octave frequencies 0.5 to 4kHz in both ears. Study instruments This study will feature a 2 kg, 30 cm tall and 20 cm wide, Cantonese-speaking humanoid social robot named KaKa. Interventions Each IG participant will receive SRAI at home for 10 weeks. This will include auditory rehabilitation and 60 min/day, 3 days/week of varied multicomponent physical activity following the World Health Organization's evidence-based recommendations. The control group will engage in physical activity at the same intensity level and frequency as the IG without a robot. Main outcome measures Physical activity levels. Data analysis Descriptive statistics, an independent sample t-test or chi square test, generalized estimating equation and thematic analysis will be used. Expected results Participants could benefit from incorporating tailored intervention for physical activity with auditory rehabilitation.

Background: Deafness is one of the nine potentially modifiable risk factors for dementia simulated by the Lancet dementia Prevention, intervention and Care Committee in 2017. Some studies have found that the risk factors of dementia in deafness system, with the increase of the degree of deafness, the risk of cognitive decline increases, while after long-term wear of hearing aids, the deterioration of immediate and delayed memory is less, and the possibility of cognitive decline slows down. Therefore, it is necessary for us to improve the auditory ability of patients with deafness through auditory intervention, so as to slow down its effect on dementia and reduce the incidence of dementia. At present, auditory intervention methods include hearing aid wearing and cochlear implant. However, there are few studies on cognitive function of presbycusis patients in China, and there is no research on how many years of auditory intervention can effectively slow down the incidence of dementia in presbycusis patients with MCI. Therefore, we intend to conduct a prospective cohort study on the changes of cognitive function of presbycusis under hearing aid intervention.
