RESUMO
OBJECTIVES: To explore the factors influencing the uptake of cochlear implants in adults, determine the impact of each factor, and to conceptualize the journey to implantation from a multistakeholder perspective. DESIGN: Concept mapping was used to integrate input from multiple stakeholders, each with their own experience and expertise. This mixed participatory method collects qualitative and quantitative data collection and enables further quantitative analysis. There were two participant cohorts: clients (cochlear implant recipients, candidates, and family members) and professionals (cochlear implant audiologists, ear, nose, and throat surgeons, administration staff, managers. and manufacturer representatives). A total of 93 people participated in the study: client cohort (n = 60, M age = 66.60 years) and professional cohort (n = 33, M age = 45.24 years). Participants brainstormed statements in response to the question "What influences people's decision to get/not get a cochlear implant?" They subsequently grouped the statements and named each group. They rated each statement as to its impact on the decision and prioritized the need for each to be changed/improved using a five-point Likert scale. Multidimensional scaling was used to produce a visual representation of the ideas and their relationship in the form of concepts. Further analysis was conducted to determine the differences between the cohorts, subcohorts, and concepts. RESULTS: One hundred ten unique statements were generated and grouped into six concepts which either directly affected the client or their environment. These concepts were: external influences (awareness and attitude of non-implant professionals about uptake, cost, logistics, the referral pathway, public awareness); uncertainties, beliefs, and fears (fears, negative effect of word of mouth, unsuccessful previous ear surgery, cosmetics of the device, misunderstanding of how a cochlear implant functions, eligibility for an implant and outcomes after implantation); health problems (mental and physical health); hearing difficulties (social, emotional, and communication impacts of hearing loss, severity of hearing loss, benefit from and experience with hearing aids); implant professionals (implant team's attitude, knowledge and relationship with clients, quality of overall service); and goals and support (clients 'hearing desires and goals, motivation, positive impact of word of mouth, family support, having a cochlear implant mentor. The six concepts fell into two overarching domains: the client-driven domain with four concepts and the external domain with two concepts. The mean rating of concepts in terms of impact on a client's decision to get an implant ranged from 2.24 (external influences, the main barrier) to 4.45 (goals and support, the main driver). Ratings significantly differed between the client and professional cohorts. CONCLUSIONS: This study increases our understanding of the factors, which influence a client's decision choose a cochlear implant as a hearing treatment. It also provides new information on the influence of the other stakeholders on the client journey. The magnitude of the generated statements in the client-driven domain highlights the pivotal role of individualized care in clinical settings in influencing a client's decision and the need for the professionals to understand a client's needs and expectations. A client's persistent hearing difficulties, goals, and support network were identified as drivers to the uptake of cochlear implants. However, the barriers identified highlight the need for a collaborative multi- and interdisciplinary approach to raise awareness in and educate non-implant hearing professionals about the cochlear implant process, as well as providing information to empower clients to make educated decisions and consider a cochlear implant as a hearing management option.

BACKGROUND: Globally, about 50 million people were living with dementia in 2015, with this number projected to triple by 2050. With no cure or effective treatment currently insight, it is vital that factors are identified which will help prevent or delay both age-related and pathological cognitive decline and dementia. Observational data have suggested that hearing loss is a potentially modifiable risk factor for dementia, but no conclusive evidence from randomised controlled trials is currently available. METHODS: The HearCog trial is a 24-month, randomised, controlled clinical trial aimed at determining whether a hearing loss intervention can delay or arrest the cognitive decline. We will randomise 180 older adults with hearing loss and mild cognitive impairment to a hearing aid or control group to determine if the fitting of hearing aids decreases the 12-month rate of cognitive decline compared with the control group. In addition, we will also determine if the expected clinical gains achieved after 12 months can be sustained over an additional 12 months and if losses experienced through the non-correction of hearing loss can be reversed with the fitting of hearing aids after 12 months. DISCUSSION: The trial will also explore the cost-effectiveness of the intervention compared to the control arm and the impact of hearing aids on anxiety, depression, physical health and quality of life. The results of this trial will clarify whether the systematic correction of hearing loss benefits cognition in older adults at risk of cognitive decline. We anticipate that our findings will have implications for clinical practice and health policy development.

OBJECTIVES: The financial burden of treatment for oral squamous cell carcinoma in Australia has never been reported, and there is a paucity of international data. Here, we report the direct costs of treatment of surgically resectable oral cancer in a tertiary public hospital in Australia over a 15-year period. MATERIALS AND METHODS: Pathology department records, records of hospital attendance and hospital finance department records were interrogated to determine the direct costs of inpatient and outpatient treatment. Costs were adjusted using the total health price index so that all costs were equivalent to costings for the 2016/2017 financial year. RESULTS: A total of 113 cases were identified as suitable for inclusion. Complete inpatient and outpatient hospital attendance and costing data for treatment and subsequent 2-year follow-up was available for 29 cases. The average total cost over the 2-year period was $92 958AUD (median $102 722, range $11 662-$181 512). On average, 92.8% of costs were incurred in the first year post-diagnosis. Inpatient costs, outpatient costs and total costs increased with increasing pathological cancer stage. Both 1- and 2-year post-diagnosis overall cost for patients with Stage 4 oral cavity cancer were more than two times greater than for patients with Stage 1 oral cancer. CONCLUSION: It is well documented that patients diagnosed at an earlier stage will have better survival outcomes, and it is assumed that the economic burden of their treatment will be less. We have shown that there is a direct correlation between cancer stage and cancer treatment cost. The findings provide clear economic support for oral cancer screening initiatives to detect earlier stage cancers, and the need to investigate novel techniques and technologies to detect oral squamous cell carcinoma early and reduce recurrence and mortality rates.

OBJECTIVE: To identify which preoperative patient characteristics influence sequential bilateral cochlear implantation performance and to create a statistical model that predicts benefit. DESIGN: Multicentre retrospective cohort study. SETTING: All patients were operated in four academic teaching hospitals in Perth, Australia, and followed up by audiologists of the Ear Science Institute Australia. PARTICIPANTS: A total of 92 postlingually deafened adult patients who had undergone sequential cochlear implantations between 19 June 1990 and 14 March 2016 were included. Patients were excluded if the 12-month follow-up consonant-nucleus-consonant (CNC) phoneme score was missing. MAIN OUTCOME MEASURE: The effect of 18 preoperative factors on the CNC phoneme score in quiet (at 65 dB SPL) with the second cochlear implant (CI2) one year after implantation. RESULTS: Two factors were positively correlated to speech understanding with CI2: Wearing a hearing aid (HA) before receiving CI2 (r = 0.46, P = 0.00) and the maximum CNC phoneme score with the first CI (CI1) (r = 0.21, P = 0.05). Two factors were negatively correlated: the length of hearing loss before CI2 in the second implanted ear (r = -0.25, P = 0.02) and preoperative pure tone average (PTA) (0.5, 1, 2 kHz) before CI2 in the second implanted ear (r = -0.27, P = 0.01). The following model could be created: predicted CNC phoneme score with CI2 (%) = 16 + (44 * HA use before CI2 (yes)) - (0.22 * length of hearing loss before CI2 (years)) + (0.23 * CNC phoneme score with CI1 (%)). Because the effect of HA use before implantation played such a major role, we also created a model after exclusion of the HA factor: Predicted CNC phoneme score with CI2 (%) = 82 - (0.17 * length of hearing loss before CI2 (years)) - (0.27 * PTA in second implanted ear before CI2 (0.5, 1, 2 kHz)) + (0.20 * CNC phoneme score with CI1 (%)). CONCLUSION: Advanced age or a long interval between implantations does not necessarily lead to poor CI2 results. Patients who are successful HA users before CI2, who have a low PTA before CI2, a high CNC phoneme score with CI1 and a limited length of hearing loss before CI2, are likely to be successful CI2 recipients.

This systematic review of the literature reveals which pre-operative factors affect sequential cochlear implantation outcomes in adults. The findings can help health care prof-essionals provide evidence-based advice on the expected benefits from a second cochlear implant (CI). We searched PubMed, EMBASE, and the Cochrane database from November 1977 to August 26, 2017, using the terms "sequential cochlear implantation"; the most frequently cited predictors for unilateral cochlear implantation performance and other potential predictors for sequential implantation outcome; and "speech perception," "localization" as well as synonyms of all of the above. Ten studies were included. The effects of age, duration of hearing loss, time between implantations, preoperative hearing, etiology of hearing loss, hearing aid use and duration of follow-up on sequential cochlear implantation performance were studied. The literature has shown that duration of deafness, age at onset of deafness, etiology of hearing loss, and preoperative speech perception score are (inversely) related to unilateral cochlear implantation outcome in adults. One would expect that these factors would also affect sequential bilateral implantation outcome. However, the best available evidence to date shows that advanced age, a long duration of deafness, or a long interval between implantations should not be considered negative factors when considering sequential bilateral cochlear implantation.
RESUMO
OBJECTIVE: Examine the accuracy of automated audiometry in a clinically heterogeneous population of adults using the KUDUwave automated audiometer. DESIGN: Prospective accuracy study. Manual audiometry was performed in a sound-treated room and automated audiometry was not conducted in a sound-treated environment. STUDY SAMPLE: 42 consecutively recruited participants from a tertiary otolaryngology department in Western Australia. RESULTS: Absolute mean differences ranged between 5.12-9.68 dB (air-conduction) and 8.26-15 dB (bone-conduction). A total of 86.5% of manual and automated 4FAs were within 10 dB (i.e. ±5 dB); 94.8% were within 15 dB. However, there were significant (p < 0.05) differences between automated and manual audiometry at 250, 500, 1000, and 2000 Hz (air-conduction) and 500 and 1000 Hz (bone-conduction). The effect of age (≥55 years) on accuracy (p = 0.014) was not significant on linear regression (p > 0.05; R(2) =( ) 0.11). The presence of a hearing loss (better ear ≥26 dB) did not significantly affect accuracy (p = 0.604; air-conduction), (p = 0.218; bone-conduction). CONCLUSIONS: This study provides clinical validation of automated audiometry using the KUDUwave in a clinically heterogeneous population, without the use of a sound-treated environment. Whilst threshold variations were statistically significant, future research is needed to ascertain the clinical significance of such variation.

OBJECTIVE: A Phase II trial was conducted to determine if nasal disinfection with a commercial Good Manufacturing Practice-manufactured 0.5% povidone-iodine nasal spray (Nasodine®) may be a useful adjunct in the management of COVID-19 by reducing viral shedding and prevention of transmission of SARS-CoV-2. The aim was to confirm the results from a human single-dose pilot study by assessing repeated and frequent doses on nasal shedding of SARS-CoV-2 from adult subjects with confirmed COVID-19. METHODS: A multicenter, randomized, double-blinded, placebo-controlled Phase II clinical trial involving adults with early COVID-19 symptoms. Baseline nasal swabs were collected to quantify pretreatment SARS-CoV-2 nasal viral load, followed by Nasodine treatment eight times daily over 3 calendar days. Daily nasal swabs were collected post-dose to assess the impact of treatment on nasal viral load, measured by log10 TCID50 in quantitative culture. RESULTS: Nasodine subjects exhibited significantly improved reduction in viral load (log10 TCID50) on Days 2-4 compared to placebo recipients (p = 0.028), rate of nasal clearance of viable virus (p = 0.032), and complete (100%) nasal and throat clearance of the virus by Day 5. No difference was seen in antigen shedding as measured by time transition from Rapid Antigen Test (RAT) positivity to RAT negativity. CONCLUSION: A total of 20 doses of Nasodine® nasal spray administered over 2.5 days significantly reduced the titers of viable SARS-CoV-2 virus in the nasal passages of COVID-19 subjects. This is the first study demonstrating the efficacy of a tolerable intranasal formulation of povidone-iodine on viral shedding in COVID-19 subjects. Nasal disinfection may diminish viral transmission to others. LEVEL OF EVIDENCE: 2 Laryngoscope, 134:3947-3952, 2024.

RESUMO
BACKGROUND: The baby boomer population will become high users of the health-care system in coming years. Self-report of hearing loss at a primary health-care visit may offer timely referrals to audiological services, but there has been no population-based study of self-reported hearing loss in the baby boomer generation. PURPOSE: To determine the clinical value and audiometric correspondence of self-reported hearing loss as a screening tool for the baby boomer population. RESEARCH DESIGN: A population-based study, Busselton Healthy Ageing Study (BHAS), surveying baby boomers born between 1946 and 1964 from the shire of Busselton, Western Australia. STUDY SAMPLE: A randomized sample of noninstitutionalized baby-boomers listed on the electoral roll (n = 6690) and resident in the shire are eligible to participate. This study reports on data from the first 1004 attendees (53.5% female) with a mean age of 56.23 (SD = 5.43). DATA COLLECTION AND ANALYSIS: Data from a self-report question on hearing loss and diagnostic pure tone audiometry was utilized for this study. Analysis included screening performance measures of self-report compared to audiometric cut-offs, receiver operator curve (ROC) to determine optimal level, analysis of variance to compare hearing status to self-report, and binary logistic regression to determine best audiometric predictors. RESULTS: Of the sample, 16% self-reported hearing loss (72.1% males). Logistic regression indicated 4000 Hz as the most important individual frequency related to self-report while the four-frequency average (500, 1000, 2000, and 4000 Hz) >25 dB in the worse ear was the most significant averaged cutoff with 68% sensitivity and 87% specificity. Of those who self-reported a hearing loss, 80% had either a four-frequency average hearing loss >25 dB in the worse ear or a high-frequency average (4000 and 8000 Hz) hearing loss greater than 35 dB in the worse ear. CONCLUSIONS: Baby boomer adults who self-report hearing impairment on direct inquiry are most likely to have a hearing loss. A simple question at a primary health care visit may facilitate a timely referral for audiological services in a baby boomer adult, who may be more amenable to rehabilitation.

BACKGROUND: This study aimed to describe available evidence of cochlear implantation delivery arrangements in adults and the outcomes by which these service models are measured. METHODS: Scoping review of English language, primary studies conducted on adults (≥18 years) with ten or more subjects, published between January 2000 and June 2022, which assessed the effects of delivery arrangements of cochlear implantation were included. MEDLINE, EMBASE, CINAHL Plus, AMED, PsycINFO, LILACS, KoreaMed, IndMed, Cochrane CRCT, ISRCTN registry, WHO ICTRP and Web of Science were systematically searched. Included studies had to have a method section explicitly measure at least one of the Cochrane Effective Practice and Organization of Care (EPOC) outcome category. Criteria for systematic reviews and delivery arrangement category based on EPOC taxonomy was included in data extraction. Data was narratively synthesized based on EPOC categories. RESULTS: A total of 8135 abstracts were screened after exclusion of duplicates, of these 357 studies fulfilled the inclusion criteria. Around 40% of the studies investigated how care is delivered, focusing on quality and safety systems. New care pathways to coordinate care and the use of information and communication technology were emerging areas. There was little evidence on continuity, coordination and integration of care, how the workforce is managed, where care is provided and changes in the healthcare environment. The main outcome measure for various delivery arrangements were the health status and performance in a test. CONCLUSION: A substantial body of evidence exists about safety and efficacy of cochlear implantation in adults, predominantly focused on surgical aspects and this area is rapidly growing. There is a lack of evidence on aspects of care delivery that may have more impact on patients' experience such as continuity, coordination and integration of care and should be a focus of future research. This would lead to a better understanding of how patient's view CI experience, associated costs and the value of different care models.

BACKGROUND AND OBJECTIVES: Studies reporting an association between hearing loss and depression in older adults are conflicting and warrant a systematic review and meta-analysis of the evidence. RESEARCH DESIGN AND METHODS: A search of academic databases (e.g., MEDLINE) and gray literature (e.g., OpenGrey) identified relevant articles published up to July 17, 2018. Cross-sectional or cohort designs were included. Outcome effects were computed as odds ratios (ORs) and pooled using random-effects meta-analysis (PROSPERO: CRD42018084494). RESULTS: A total of 147,148 participants from 35 studies met inclusion criteria. Twenty-four studies were cross-sectional and 11 were cohort designs. Overall, hearing loss was associated with statistically significantly greater odds of depression in older adults (OR = 1.47, 95% confidence interval [CI] = 1.31-1.65). When studies were stratified by design, hearing loss was associated with greater odds of depression in cross-sectional studies (OR = 1.54, 95% CI = 1.31-1.80) and cohort studies (OR = 1.39, 95% CI = 1.16 - 1.67), and there was no difference between cross-sectional or cohort effect estimates (Q = 0.64, p = .42). There was no effect of moderator variables (i.e., hearing aid use) on the association between hearing loss and depression, but these findings must be interpreted with caution. There was no presence of publication bias but certainty in the estimation of the overall effect was classified as "low." DISCUSSION AND IMPLICATIONS: Older adults may experience increased odds of depression associated with hearing loss, and this association may not be influenced by study or participant characteristics.

PURPOSE: This study examined the central auditory processing (CAP) assessment results of adults between 45 and 85 years of age with probable pre-clinical Alzheimer's disease - i.e., individuals with subjective memory complaints (SMCs) as compared to those who were not reporting significant levels of memory complaints (non-SMCs). It was hypothesized that the SMC group would perform significantly poorer on tests of central auditory skills compared to participants with non-SMCs (control group). METHODS: A total of 95 participants were recruited from the larger Western Australia Memory Study and were classified as SMCs (N = 61; 20 males and 41 females, mean age 71.47 ±7.18 years) and non-SMCs (N = 34; 10 males, 24 females, mean age 68.85 ±7.69 years). All participants completed a peripheral hearing assessment, a CAP assessment battery including Dichotic Digits, Duration Pattern Test, Dichotic Sentence Identification, Synthetic Sentence Identification with Ipsilateral Competing Message (SSI-ICM) and the Quick-Speech-in-Noise, and a cognitive screening assessment. RESULTS: The SMCs group performed significantly poorer than the control group on SSI-ICM -10 and -20 dB signal-to-noise conditions. No significant differences were found between the two groups on the peripheral hearing threshold measurements and other CAP assessments. CONCLUSIONS: The results suggest that individuals with SMCs perform poorly on specific CAP assessments in comparison to the controls. The poor CAP in SMC individuals may result in a higher cost to their finite pool of cognitive resources. The CAP results provide yet another biomarker that supports the hypothesis that SMCs may be a primary indication of neuropathological changes in the brain. Longitudinal follow up of individuals with SMCs, and decreased CAP abilities should inform whether this group is at higher risk of developing dementia as compared to non-SMCs and those SMC individuals without CAP difficulties.
RESUMO
INTRODUCTION: A number of studies have reported an association between peripheral hearing impairment, central auditory processing and Alzheimer's disease (AD) and its preclinical stages. Both peripheral hearing impairment and central auditory processing disorders are observed many years prior to the clinical manifestation of AD symptoms, hence, providing a long window of opportunity to investigate potential interventions against neurodegenerative processes. This paper outlines the protocol for a systematic review of studies examining the central auditory processing functions in AD and its preclinical stages, investigated through behavioural (clinical assessments that require active participation) central auditory processing tests. METHODS AND ANALYSIS: We will use the keywords and Medical Subject Heading terms to search the following electronic databases: MEDLINE, PsychINFO, PubMed, Scopus, EMBASE and CINAHL Plus. Studies including assessments of central auditory function in adults diagnosed with dementia, AD and its preclinical stages that were published before 8 May 2019 will be reviewed. This review protocol will be reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols guidelines. Data analysis and search results will be reported in the full review. This manuscript has designed the protocols for a systematic review that will identify the behavioural clinical central auditory processing measures that are sensitive to the changes in auditory function in adults with AD and its preclinical stages. Such assessments may subsequently help to design studies to examine the potential impact of hearing and communication rehabilitation of individuals at risk of AD. ETHICS AND DISSEMINATION: Ethical approval is not required as this manuscript only reports the protocols for conducting a systematic review as primary data will only be reviewed and not be collected. The results of this systematic review will be disseminated through publication and in scientific conferences. PROSPERO REGISTRATION NUMBER: CRD42017078272.

OBJECTIVES: To explore the prognostic and discriminatory ability of the AJCC 8th Edition Oral Cavity cancer staging in a non-North American population, and compare it to the previously used AJCC 7th Edition. MATERIALS AND METHODS: Retrospective chart review was performed at a tertiary referral Otolaryngology, Head Neck and Skull Base Department in Australia, from June 2002 to June 2017. Oral cavity squamous cell carcinoma cases were staged according to AJCC 8th Edition, which was compared to AJCC 7th Edition staging, for disease-free survival (DFS) and overall survival (OS). DFS and OS were analysed using Kaplan-Meier curves. RESULTS: There were 118 patients treated for OSCC, with an average age of 61â¯years, 63% were male. Overall survival grouped by stage demonstrated statistically significant discrimination between cancer stages using both the AJCC 7th and AJCC 8th Editions. AJCC 7th Edition did not discriminate between stages for DFS. Conversely, AJCC 8th Edition did statistically significantly discriminate for DFS (pâ¯=â¯0.0002). The DFS for both Stage 4a and 4b was significantly worse than cases in Stage 1. AJCC 8th Edition T stage was statistically significantly related to DFS (pâ¯=â¯0.0199), while the AJCC 7th Edition T stage was not. CONCLUSION: The AJCC Cancer Staging Manual 8th Edition includes both the depth of primary tumour invasion and extracapsular extension of lymph node metastases. The AJCC 8th Edition OSCC staging system showed improved disease-free survival discrimination between overall stages and between T categories, while AJCC 7th Edition did not.

Age-related hearing loss (ARHL), presbycusis, is a chronic health condition that affects approximately one-third of the world's population. The peripheral and central hearing alterations associated with age-related hearing loss have a profound impact on perception of verbal and non-verbal auditory stimuli. The high prevalence of hearing loss in the older adults corresponds to the increased frequency of dementia in this population. Therefore, researchers have focused their attention on age-related central effects that occur independent of the peripheral hearing loss as well as central effects of peripheral hearing loss and its association with cognitive decline and dementia. Here we review the current evidence for the age-related changes of the peripheral and central auditory system and the relationship between hearing loss and pathological cognitive decline and dementia. Furthermore, there is a paucity of evidence on the relationship between ARHL and established biomarkers of Alzheimer's disease, as the most common cause of dementia. Such studies are critical to be able to consider any causal relationship between dementia and ARHL. While this narrative review will examine the pathophysiological alterations in both the peripheral and central auditory system and its clinical implications, the question remains unanswered whether hearing loss causes cognitive impairment or vice versa.
RESUMO
This systematic review and meta-analysis examined the efficacy of auditory training and cognitive training to improve cognitive function in adults with hearing loss. A literature search of academic databases (e.g., MEDLINE, Scopus) and gray literature (e.g., OpenGrey) identified relevant articles published up to January 25, 2018. Randomized controlled trials (RCTs) or repeated measures designs were included. Outcome effects were computed as Hedge's g and pooled using random-effects meta-analysis (PROSPERO: CRD42017076680). Nine studies, five auditory training, and four cognitive training met the inclusion criteria. Following auditory training, the pooled effect was small and statistically significant for both working memory ( g = 0.21; 95% CI [0.05, 0.36]) and overall cognition ( g = 0.19; 95% CI [0.07, 0.31]). Following cognitive training, the pooled effect for working memory was small and statistically significant ( g = 0.34; 95% CI [0.16, 0.53]), and the pooled effect for overall cognition was large and significant ( g = 1.03; 95% CI [0.41, 1.66]). However, this was dependent on the classification of training approach. Sensitivity analyses revealed no statistical difference between the effectiveness of auditory and cognitive training for improving cognition upon removal of a study that used a combined auditory-cognitive approach, which showed a very large effect. Overall certainty in the estimation of effect was "low" for auditory training and "very low" for cognitive training. High-quality RCTs are needed to determine which training stimuli will provide optimal conditions to improve cognition in adults with hearing loss.

Purpose: This review examined (a) the current evidence from studies on teleaudiology applications for rehabilitation of adults with hearing impairment with hearing aids and (b) whether it is sufficient to support the translation into routine clinical practice. Method: A search strategy and eligibility criteria were utilized to include articles specifically related to hearing aid fitting and follow-up procedures that are involved in consultations for the rehabilitation of adults, where the service was provided by the clinician by teleaudiology. A search using key words and Medical Subject Headings (MeSH) was conducted on the main electronic databases that index health-related studies. The included studies were assessed using validated evaluation tools for methodological quality, level of evidence, and grade recommendations for application into practice. Results: Fourteen studies were identified as being within the scope of this review. The evaluation tools showed that none of these studies demonstrated either a strong methodological quality or high level of evidence. Analysis of evidence identified 19 activities, which were classified into service outcomes categories of feasibility, barriers, efficiency, quality, and effectiveness. Recommendations could be made regarding the (a) feasibility, (b) barriers, and (c) efficiency of teleaudiology for the rehabilitation of hearing loss with hearing aids. Conclusion: This review provides up-to-date evidence for teleaudiology hearing aid services in new and experienced hearing aid users in different practice settings. Findings direct future research priorities to strengthen evidence-based practice. There is a need for further studies of many aspects of teleaudiology services for rehabilitation with hearing aids to support their implementation into clinical practice.

BACKGROUND: Age-related hearing loss (ARHL) and depression are considered leading causes of disability in older adults. This cross-sectional study investigated the association between the severity of speech and high-frequency ARHL and depression, anxiety and stress in older adults. STUDY DESIGN: Cross-sectional study of a community-derived sample of adult volunteers. METHODS: A hearing assessment was completed by 151 participants (73 males and 78 females; Mâ¯=â¯64.44⯱â¯10.77 years). Based on their better-ear speech (0.5, 1, 2, & 4â¯kHz) and high-frequency (6 & 8â¯kHz) hearing thresholds, they were divided three groups: those with normal hearing; those with mild to moderate hearing loss; and those with moderately severe to profound hearing loss. All participants also completed the Depression, Anxiety and Stress Scale (DASS-21). RESULTS: A binomial logistic regression analysis revealed that the respective odds ratios (ORs) (95% confidence interval) of clinically significant depression, anxiety and stress for participants with a moderately severe to profound hearing loss across the speech frequency range were: 27.51 (3.25, 232.95), 5.89 (1.95, 17.73) and 5.64 (1.55, 20.48). Similarly, the respective ORs of clinically significant depression, anxiety and stress were 6.54 (0.75, 57.02), 6.21 (1.52, 25.33) and 5.32 (1.02, 27.75) for participants with moderately severe to profound hearing loss across high frequencies. The non-parametric Cuzik test revealed a statistically significant positive (pâ¯<â¯.05) trend of association between both better-ear speech and high-frequency hearing loss and DASS scores. CONCLUSION: The observed graded associations suggest that hearing loss is a causative factor for clinically significant depression, anxiety and stress symptoms.

BACKGROUND: A significant relationship between hearing loss and cognitive impairment has been previously reported. Overall, improvement in speech perception in quiet and quality of life has been observed after cochlear implantation. However, the impact of hearing loss treatment using cochlear implantation on cognitive functions is yet to be fully elucidated. OBJECTIVE: To investigate the impact of cochlear implantation on cognitive and psychological functions of older adults. STUDY DESIGN: Prospective patient-control study. PARTICIPANTS: A total of 39 participants took part in the study: 23 cochlear implant (CI) candidates (Mâ=â69.04â±â12.35âyr) and 16 CI recipients (Mâ=â61.75â±â15.62âyr). All participants completed an assessment of hearing (pure-tone thresholds and speech perception in quiet), and a computerised, nonverbal test battery of cognitive function assessment, as well as a depression, anxiety, and stress scale. RESULTS: Independent-sample t test scores for the changes between 0 and 12 months revealed that CI recipients performed significantly better on measures of simple reaction time, cognitive flexibility, paired-associate learning, working memory, and strategy use (pâ<â0.05) compared with implant candidates. Compared with the candidates, recipients also showed significantly lower stress scores (pâ<â0.05) after 1 year use of a CI. CONCLUSION: Our results indicate that even in participants with a long duration, severe to profound hearing loss, cochlear implantation has some impact on improving a number of cognitive functions. This finding warrants future longitudinal investigations with a large sample size to examine if the observed cognitive enhancement benefits are sustainable.

OBJECTIVE: To review the literature on techniques for creation of chronic tympanic membrane perforations (TMP) in animal models. Establishing such models in a laboratory setting will have value if they replicate many of the properties of the human clinical condition and can thus be used for investigation of novel grafting materials or other interventions. METHODS: A literature search of the PubMed database (1950-August 2014) was performed. The search included all English-language literature published attempts on chronic or delayed TMP in animal models. Studies of non English-language or acute TMP were excluded. RESULTS: Thirty-seven studies were identified. Various methods to create TMP in animals have been used including infolding technique, thermal injury, re-myringotomy, and topical agents including chemicals and growth factor receptor inhibitors. The most common type of animal utilized was chinchilla, followed by rat and guinea pig. Twenty three of the 37 studies reported success in achieving chronic TMP animal model while 14 studies solely delayed the healing of TMP. Numerous experimental limitations were identified including TMP patency duration of <8 weeks, lack of documentation of total number of animals attempted and absence of proof for chronicity with otoscopic and histologic evidence. CONCLUSION: The existing literature demonstrates the need for an ideal chronic TMP animal model to allow the development of new treatments and evaluate the risk of their clinical application. Various identified techniques seem promising, however, a need was identified for standardization of experimental design and evidence to address multiple limitations.
