Abstract
This study aimed to provide a comprehensive understanding of the influence of hearing loss on social participation in older adults and including its facilitators and barriers. Following the rigorous methodological framework of scoping studies, nine multidisciplinary databases were searched with 44 keywords. Published mainly in the last decade, 41 studies using primarily a quantitative cross-sectional design were selected. Older adults with hearing loss have been found to have difficulty maintaining relationships and social activities. While social support and engaged-coping strategies were major facilitators of social participation, barriers included greater hearing loss, communication difficulties, comorbidities and reduced mental health. To better promote the social participation of older adults, early detection of hearing loss, holistic assessment, and interprofessional collaboration must be considered. Future research is necessary to better address the stigma related to hearing loss in older adults and challenges of early detection, and to propose innovative solutions to develop interprofessional collaboration.

Abstract
PURPOSE Hearing loss has become a significant public health concern because of its association with physical health, cognition, and emotional well-being. Age-related hearing loss is the third leading cause of global years lived with disability after lower back pain and migraine. Among other sensory disorders, hearing loss is ranked first. To help mitigate these health concerns, access to affordable hearing health care across rural and urban communities will be necessary. METHOD For this study, the needs of rural communities and their residents with hearing loss were explored. Individual interviews and focus group discussions with 26 adults with hearing loss, 14 friends and family of those with hearing loss, and 25 community members who worked and lived in rural communities were conducted. RESULTS Collectively, four themes emerged from qualitative analysis of the comments from all three groups, including Communication and Other Related Hearing Loss Issues, Social and Emotional Issues, Dealing with Hearing Loss, and Addressing Hearing Loss in the Community. Factors associated with the themes were mapped onto the Meikirch Model of Health to determine potential areas of intervention within the individual, society, and environment components of the model. CONCLUSION Future care mitigating health concerns for adults with hearing loss living in rural communities will involve interprofessional collaboration and increased access to hearing health care.

Abstract
PURPOSE Access and affordability of hearing health care varies depending on residency and individual financial means. Those living in rural areas have limited health care resources and experience higher levels of poverty compared to those living in urban regions. The purpose of this study was to determine the feasibility of interprofessional collaboration among physicians and audiologists and pharmacists and audiologists to improve access and affordability of hearing health care in rural communities. METHOD Sixteen family physicians and medicine residents and 15 community pharmacists participated in the study. Physicians and residents completed an online survey to assess education regarding hearing health care and their understanding of hearing loss intervention. They also participated in small virtual focus group discussions. Pharmacists participated in virtual discussions based on guided questions. RESULTS The discussions with both physicians and pharmacists highlighted the need for more education, resources, and awareness of the negative impact of hearing loss on overall quality of life. Comments from these discussions were placed within the socio-ecological model of health behavior to increase understanding of hearing health behavior. CONCLUSIONS Increased collaboration among medical professionals has the potential to improve access to hearing health care for those living in audiologically underserved regions of the country. Further research will identify how to increase effective and sustainable hearing health care resources in rural communities.

ASK1 is a novel molecular target for preventing aminoglycoside-induced hair cell death. J Mol Med (Berl) 2022; 100:797-813. [PMID: 35471608 PMCID: PMC9110505 DOI: 10.1007/s00109-022-02188-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2021] [Revised: 02/07/2022] [Accepted: 03/03/2022] [Indexed: 10/31/2022]
Abstract
Aminoglycoside antibiotics are lifesaving medicines, crucial for the treatment of chronic or drug resistant infections. However, aminoglycosides are toxic to the sensory hair cells in the inner ear. As a result, aminoglycoside-treated individuals can develop permanent hearing loss and vestibular impairment. There is considerable evidence that reactive oxygen species (ROS) production and the subsequent phosphorylation of c-Jun N-terminal kinase (JNK) and P38 mitogen-activated protein kinase (P38) drives apoptosis in aminoglycoside-treated hair cells. However, treatment strategies that directly inhibit ROS, JNK, or P38 are limited by the importance of these molecules for normal cellular function. Alternatively, the upstream regulator apoptosis signal-regulating kinase 1 (ASK1/MAP3K5) is a key mediator of ROS-induced JNK and P38 activation under pathologic but not homeostatic conditions. We investigated ASK1 as a mediator of drug-induced hair cell death using cochlear explants from Ask1 knockout mice, demonstrating that Ask1 deficiency attenuates neomycin-induced hair cell death. We then evaluated pharmacological inhibition of ASK1 with GS-444217 as a potential otoprotective therapy. GS-444217 significantly attenuated hair cell death in neomycin-treated explants but did not impact aminoglycoside efficacy against P. aeruginosa in the broth dilution test. Overall, we provide significant pre-clinical evidence that ASK1 inhibition represents a novel strategy for preventing aminoglycoside ototoxicity. KEY MESSAGES: • ASK1 is an upstream, redox-sensitive regulator of P38 and JNK, which are known mediators of hair cell death. • Ask1 knockout does not affect hair cell development in vivo, but significantly reduces aminoglycoside-induced hair cell death in vitro. • A small-molecule inhibitor of ASK1 attenuates neomycin-induced hair cell death, and does not impact antibiotic efficacy in vitro. • ASK1 may be a novel molecular target for preventing aminoglycoside-induced hearing loss.

Abstract
Hearing loss in adults is a significant public health problem throughout the world. Undiagnosed and untreated hearing loss causes a measurable impact on health and social, occupational, and emotional well-being of those affected. In spite of a wide array of health care resources to identify and manage hearing loss, there exist vast disparities in outcomes, as well as access to and utilization of hearing healthcare. Hearing rehabilitation outcomes may vary widely among different populations and there is a pressing need to understand, in a broader sense, the factors that influence equitable outcomes, access, and utilization. These factors can be categorized according to the widely accepted framework of social determinants of health, which is defined by the World Health Organization as "the conditions in which people are born, grow, work, live, and age." According to Healthy People 2030, these determinants can be broken into the following domains: healthcare access and quality, education access and quality, social and community context, economic stability, and neighborhood and built environment. This article defines these domains and examines the published research and the gaps in research of each of these domains, as it pertains to hearing health and healthcare. Herein, we review foundational sources on the social determinants of health and hearing-related research focused on the topic. Further consideration is given to how these factors can be evaluated in a systematic fashion and be incorporated into translational research and hearing health care.

Abstract
Hearing loss is a global public health problem with high prevalence and profound impacts on health. Cochlear implantation (CI) is a well-established evidence-based treatment for hearing loss; however, there are significant disparities in utilization, access, and clinical outcomes among different populations. While variations in CI outcomes are influenced by innate biological differences, a wide array of social, environmental, and economic factors significantly impact optimal outcomes. These differences in hearing health are rooted in inequities of health-related socioeconomic resources. To define disparities and advance equity in CI, there is a pressing need to understand and target these social factors that influence equitable outcomes, access, and utilization. These factors can be categorized according to the widely accepted framework of social determinants of health, which include the following domains: healthcare access/quality, education access/quality, social and community context, economic stability, and neighborhood and physical environment. This article defines these domains in the context of CI and examines the published research and the gaps in research of each of these domains. Further consideration is given to how these factors can influence equity in CI and how to incorporate this information in the evaluation and management of patients receiving cochlear implants.

Abstract
For social animals that communicate acoustically, hearing loss and social isolation are factors that independently influence social behavior. In human subjects, hearing loss may also contribute to objective and subjective measures of social isolation. Although the behavioral relationship between hearing loss and social isolation is evident, there is little understanding of their interdependence at the level of neural systems. Separate lines of research have shown that social isolation and hearing loss independently target the serotonergic system in the rodent brain. These two factors affect both presynaptic and postsynaptic measures of serotonergic anatomy and function, highlighting the sensitivity of serotonergic pathways to both types of insult. The effects of deficits in both acoustic and social inputs are seen not only within the auditory system, but also in other brain regions, suggesting relatively extensive effects of these deficits on serotonergic regulatory systems. Serotonin plays a much-studied role in depression and anxiety, and may also influence several aspects of auditory cognition, including auditory attention and understanding speech in challenging listening conditions. These commonalities suggest that serotonergic pathways are worthy of further exploration as potential intervening mechanisms between the related conditions of hearing loss and social isolation, and the affective and cognitive dysfunctions that follow.

Abstract
Many drugs on the World Health Organization's list of critical medicines are ototoxic, destroying sensory hair cells within the ear. These drugs preserve life, but patients can experience side effects including permanent hearing loss and vestibular dysfunction. Aminoglycoside ototoxicity was first recognised 80 years ago. However, no preventative treatments have been developed. In order to develop such treatments, we must identify the factors driving hair cell death. In vivo, studies of cell death are typically conducted using mouse models. However, a robust model of aminoglycoside ototoxicity does not exist. Previous studies testing aminoglycoside delivery via intraperitoneal or subcutaneous injection have produced variable ototoxic effects in the mouse. As a result, surgical drug delivery to the rodent ear is often used to achieve ototoxicity. However, this technique does not accurately model clinical practice. In the clinic, aminoglycosides are administered to humans intravenously (i.v.). However, repeated i.v. delivery has not been reported in the mouse. This study evaluated whether repeated i.v. administration of amikacin or tobramycin would induce hearing loss. Daily i.v. injections over a two-week period were well tolerated and transient low frequency hearing loss was observed in the aminoglycoside treatment groups. However, the hearing changes observed did not mimic the high frequency patterns of hearing loss observed in humans. Our results indicate that the i.v. delivery of tobramycin or amikacin is not an effective technique for inducing ototoxicity in mice. This result is consistent with previously published reports indicating that the mouse cochlea is resistant to systemically delivered aminoglycoside ototoxicity.

Abstract
Although self-management interventions can improve symptoms and disease among older adults, there is a dearth of literature on how self-management behaviors may improve factors related to the older adults' physical function. To fill this gap in the literature, we describe the patient-directed self-management goals in nursing visits that relate to physical function as part of a multi-component program. We analyze the self-management goals and outcomes of 367 low- income older adults with functional limitations who participated in the CAPABLE program: a program to reduce the health effects of impaired physical function in low-income older adults. We focus on the following self-management goals that participants chose with the nurses: pain management, depressive symptoms, incontinence, fall prevention, and communication with healthcare providers. The majority of participants chose pain (50%) or fall prevention (51%) as goals and partially or fully met their goals. Improvements across these areas may lead to improved physical function.
