Purpose: To investigate the auditory behavior of patients with chronic renal failure (CRF) undergoing kidney transplantation.
Methods: Thirty patients were evaluated, 10 (33.33%) females and 20 (66.67%) males, aging from 13 to 26 years (average, 16.97 years; standard deviation, 3.60 years). Patients underwent the following procedures: anamnesis, otolaryngological examination, audiological evaluation (pure tone and high frequency), acoustic impedance measurements and central auditory processing evaluation. A control group was used to compare the high-frequency audiometry results.
Results: The following observations were made: absence of auditory complaints at the time of anamnesis; pure-tone audiometry was predominantly normal; patients presented lower hearing levels at the high-frequency audiometry, when compared to the control group, and as for the acoustic impedance measurements, curves of the type A were predominant; there was a change of the central auditory processing for 14 patients (46.67%) in the Staggered Spondaic Word Test (SSW); there was a significant difference between the age variable and the result of the pure-tone audiometry, that is, hearing sensitivity in thresholds from 250Hz to 8,000Hz decreased with advancing age; and the relation between the type of donor and the SSW test result was significant. Rates were higher when the patients had been transplanted from deceased donors compared to living donors.
Conclusion: There were no changes in conventional audiological and high-frequency evaluation, or in the central auditory processing. Professionals involved in the care of kidney transplantation recipients must be better informed about the care, prevention, and early identification of auditory disorders.

Mapping patterns of thought onto brain activity during movie-watching.

Movie-watching is a central aspect of our lives and an important paradigm for understanding the brain mechanisms behind cognition as it occurs in daily life. Contemporary views of ongoing thought argue that the ability to make sense of events in the 'here and now' depend on the neural processing of incoming sensory information by auditory and visual cortex, which are kept in check by systems in association cortex. However, we currently lack an understanding of how patterns of ongoing thoughts map onto the different brain systems when we watch a film, partly because methods of sampling experience disrupt the dynamics of brain activity and the experience of movie-watching.

Acute exercise is linked to memory improvement. Several mediators may influence the effect of exercise such as the type of exercise (aerobic exercise, muscle stretching). The primary aim was to analyze memory outcomes after a 20-min bout of aerobic exercise or muscle stretching.

Background: The early diagnosis of glottic laryngeal cancer is the key to successful treatment, and machine learning (ML) combined with narrow-band imaging (NBI) laryngoscopy provides a new idea for the early diagnosis of glottic laryngeal cancer.
Objective: To explore the clinical applicability of the diagnosis of early glottic cancer based on ML combined with NBI.
Material And Methods: A retrospective study was conducted on 200 patients diagnosed with laryngeal mass, and the general clinical characteristics and pathological results of the patients were collected.
The cochlear nuclear complex (CN), the starting point for all central auditory processing, encompasses a suite of neuronal cell types highly specialized for neural coding of acoustic signals. However, the molecular logic governing these specializations remains unknown. By combining single-nucleus RNA sequencing and Patch-seq analysis, we reveal a set of transcriptionally distinct cell populations encompassing all previously observed types and discover multiple hitherto unknown subtypes with anatomical and physiological identity.

Background: Auditory verbal hallucinations (AVHs) in schizophrenia (SCZ) are linked to brain network abnormalities. Resting-state fMRI studies often assume stable networks during scans, yet dynamic changes related to AVHs are not well understood.
Methods: We analyzed resting-state fMRI data from 60 SCZ patients with persistent AVHs (p-AVHs), 39 SCZ patients without AVHs (n-AVHs), and 59 healthy controls (HCs), matched for demographics.
