Background: Traditional paradigms of care recommend close audiology follow-up and regular speech perception outcomes assessment indefinitely for cochlear implant (CI) recipients after device activation. However, there is scant published data on actual compliance with this paradigm in clinical practice.
Methods: A multi-center cochlear implant database was queried to identify follow-up rates after cochlear implantation. Follow-up rates where speech perception outcomes assessment occurred at 1-, 3-, 6-, 12-, 18-, and 24-months post-activation were determined by tabulating observed follow-up divided by expected follow-up (O/E ratio) expressed as a percentage. To determine all-cause audiology follow-up rates (with or without testing speech perception outcomes assessment), the database patients from two participating centers (one private practice and one academic center) were similarly analyzed using electronic health record (EHR) data to calculate O/E rates where audiology follow-up occurred for any reason.
Results: O/E follow-up rates where speech perception outcomes assessment occurred was 42, 40, 31, 29, 5, and 22% for 1-, 3-, 6-, 12-, 18-, and 24-months post-activation, respectively (n = 2,554). All-cause audiology follow-up rates (with or without speech perception outcomes assessment) using EHR-confirmed data from two individual centers were 97, 94, 81, 66, 41, and 35% at 1-, 3-, 6-, 12-, 18-, and 24-months post-activation visits, respectively (n = 118).
Conclusions: Compliance with audiology follow-up and speech perception outcomes assessment is generally low and decreases significantly as time post-activation increases. Future paradigms of care for CI should be designed recognizing the significant attrition that occurs with CI follow-up.

Background: Cochlear implants (CIs) have the potential to facilitate auditory restoration in deaf children and contribute to the maturation of the auditory cortex. The type of CI may impact hearing rehabilitation in children with CI. We aimed to study central auditory processing activation patterns during speech perception in Mandarin-speaking pediatric CI recipients with different device characteristics.

Previous research suggests that emotional prosody perception is impaired in neurodegenerative diseases like Alzheimer's disease (AD) and primary progressive aphasia (PPA). However, no previous research has investigated emotional prosody perception in these diseases under non-ideal listening conditions. We recruited 18 patients with AD, and 31 with PPA (nine logopenic (lvPPA); 11 nonfluent/agrammatic (nfvPPA) and 11 semantic (svPPA)), together with 24 healthy age-matched individuals.

Background: Theories highlight the important role of chronic stress in remodeling HPA-axis responsivity under stress. The Perceived Stress Scale (PSS) is one of the most widely used measures of enduring stress perceptions, and no previous studies have evaluated whether greater perceptions of stress on the PSS are associated with cortisol hypo- or hyperactivity responses to the Trier Social Stress Test (TSST).
Objective: To examine if high perceived stress over the past month, as measured by the PSS, alters cortisol and subjective acute stress reactivity to the TSST in healthy young adults.
Sensory representations and pupil-indexed listening effort provide complementary contributions to multi-talker speech intelligibility.

Multi-talker speech intelligibility requires successful separation of the target speech from background speech. Successful speech segregation relies on bottom-up neural coding fidelity of sensory information and top-down effortful listening. Here, we studied the interaction between temporal processing measured using Envelope Following Responses (EFRs) to amplitude modulated tones, and pupil-indexed listening effort, as it related to performance on the Quick Speech-in-Noise (QuickSIN) test in normal-hearing adults.

Background/objectives: Adult hearing-impaired patients qualifying for cochlear implants typically exhibit less than 60% sentence recognition under the best hearing aid conditions, either in quiet or noisy environments, with speech and noise presented through a single speaker. This study examines the influence of deep neural network-based (DNN-based) noise reduction on cochlear implant evaluation.
Methods: Speech perception was assessed using AzBio sentences in both quiet and noisy conditions (multi-talker babble) at 5 and 10 dB signal-to-noise ratios (SNRs) through one loudspeaker.
