Prevalence of presbycusis in an otologically normal population

Characteristics of Otologic Disease Among Patients With Primary Ciliary Dyskinesia

Importance

Otologic disease is common among people with primary ciliary dyskinesia (PCD), yet little is known about its spectrum and severity.

Objective

To characterize otologic disease among participants with PCD using data from the Ear-Nose-Throat Prospective International Cohort.

Design, Setting, and Participants

This cross-sectional analysis of baseline cohort data from February 2020 through July 2022 included participants from 12 specialized centers in 10 countries. Children and adults with PCD diagnoses; routine ear, nose, and throat examinations; and completed symptom questionnaires at the same visit or within 2 weeks were prospectively included.

Exposures

Potential risk factors associated with increased risk of ear disease.

Main Outcomes and Measures

The prevalence and characteristics of patient-reported otologic symptoms and findings from otologic examinations, including potential factors associated with increased risk of ear inflammation and hearing impairment.

Results

A total of 397 individuals were eligible to participate in this study (median [range] age, 15.2 [0.2-72.4] years; 186 (47%) female). Of the included participants, 204 (51%) reported ear pain, 110 (28%) reported ear discharge, and 183 (46%) reported hearing problems. Adults reported ear pain and hearing problems more frequently when compared with children. Otitis media with effusion-usually bilateral-was the most common otoscopic finding among 121 of 384 (32%) participants. Retracted tympanic membrane and tympanic sclerosis were more commonly seen among adults. Tympanometry was performed for 216 participants and showed pathologic type B results for 114 (53%). Audiometry was performed for 273 participants and showed hearing impairment in at least 1 ear, most commonly mild. Season of visit was the strongest risk factor for problems associated with ear inflammation (autumn vs spring: odds ratio, 2.40; 95% CI, 1.51-3.81) and age 30 years and older for hearing impairment (41-50 years vs ≤10 years: odds ratio, 3.33; 95% CI, 1.12-9.91).

Conclusion and Relevance

In this cross-sectional study, many people with PCD experienced ear problems, yet frequency varied, highlighting disease expression differences and possible clinical phenotypes. Understanding differences in otologic disease expression and progression during lifetime may inform clinical decisions about follow-up and medical care. Multidisciplinary PCD management should be recommended, including regular otologic assessments for all ages, even without specific complaints.

Does cognitive impairment precede self-reported poor hearing? Results from the English longitudinal study of ageing

OBJECTIVE

To investigate whether cognitive impairment precedes self-reported poor hearing in adults aged 50 and older over a 14-year period.

DESIGN

Biennial longitudinal study.

STUDY SAMPLE

The data came from the English Longitudinal Study of Ageing carried out in England between 2002 and 2016, with 11,391 individuals aged 50 years and older. For this study, ELSA participants who had a positive perception of hearing at the beginning of the analysis in 2002 (n = 8,895) were eligible. The dependent variable was self-reported poor hearing, and the exposure measure was cognitive impairment. The analyses were performed using Generalised Estimation Equations and adjusted for gender, age, educational level, household wealth, smoking, alcohol consumption, depressive symptoms, ADL/IADL disability, physical activity level, diabetes, and cardiovascular disease.

RESULTS

The results showed 33% increased odds of self-reported poor hearing in individuals with cognitive impairment. In the fully adjusted model, individuals who presented cognitive impairment in the previous wave had, over time, 10% increased odds (95% CI: 1.02; 1.19) of presenting self-reported poor hearing.

CONCLUSIONS

The exposure to cognitive impairment was associated with a subsequent self-reported poor hearing. These data represent important tools for improving cognitive and hearing impairment diagnosis and treatment.

Self-Reported Hearing Loss and Associated Factors in Older Adults at a Memory Clinic

Purpose The prevalence of dementia has increased in recent years and, along with hearing loss, can negatively impact the health of older adults. The purpose of this retrospective cross-sectional study was to establish self-reported hearing loss and associated factors in older adults at a memory clinic. Method Researchers conducted a retrospective cross-sectional study on factors associated with self-reported hearing loss (i.e., lifestyle, general health, cognition, functional capacity). Data were taken from medical records of older adults (≥ 60 years old) who received care between 2017 and 2018 at a memory clinic located at the Southern Santa Catarina University in Brazil. Analysis included the Pearson chi-squared test and logistic regression, estimation of the crude and adjusted odds ratios (OR), with respective confidence intervals of 95%. Results Researchers analyzed the medical records of 257 older adults and verified a prevalence of 13.2% of these adults with self-reported hearing loss. There was a higher prevalence of the outcome (i.e., self-reported hearing loss) in older adults who reported tinnitus (35.2%), those with mild cognitive impairment (14.7%), and those who were sedentary (19.2%). After adjustment for confusion factors, tinnitus (OR = 4.63; p = .019) and sedentarism (OR = 2.89; p = .029) were still associated with the outcome. Conclusions Tinnitus and sedentarism were associated with hearing loss in older adults receiving care at a memory clinic. As a public health issue, presbycusis needs to be included in the health planning and health promotion agendas, with effective control, prevention, and treatment measures.

Ageing and multisensory integration: A review of the evidence, and a computational perspective

The processing of multisensory signals is crucial for effective interaction with the environment, but our ability to perform this vital function changes as we age. In the first part of this review, we summarise existing research into the effects of healthy ageing on multisensory integration. We note that age differences vary substantially with the paradigms and stimuli used: older adults often receive at least as much benefit (to both accuracy and response times) as younger controls from congruent multisensory stimuli, but are also consistently more negatively impacted by the presence of intersensory conflict. In the second part, we outline a normative Bayesian framework that provides a principled and computationally informed perspective on the key ingredients involved in multisensory perception, and how these are affected by ageing. Applying this framework to the existing literature, we conclude that changes to sensory reliability, prior expectations (together with attentional control), and decisional strategies all contribute to the age differences observed. However, we find no compelling evidence of any age-related changes to the basic inference mechanisms involved in multisensory perception.
