Background: Data from the telephone interview portion of the New York Farm Family Health and Hazard Surveillance were used to study self-reported hearing loss in New York farmers.
Methods: One thousand six hundred and twenty-two persons completed the hearing loss and noise exposure interview. Hearing loss was defined as at least some trouble hearing in one or both ears. Predictors of hearing loss were determined using logistic regression.
Results: Twenty-two percent of participants reported hearing loss. From the logistic regression, significant confounders are age (P = 0.0001), gender (P = 0.0001), being from a livestock farm (P = 0.012), and loss of consciousness due to head trauma (P = 0.04). Significant noise exposures are more hours of lifetime exposure to noisy farm equipment (P = 0.001) and having had a noisy non-farm job (with some hearing protection P = 0.002, without any hearing protection P = 0.0001).
Conclusions: Farm noise exposure is a serious risk to the hearing of this population. Although use of hearing protection should be encouraged, replacing and modifying farm equipment to decrease noise at the source should be the first priority.

Purpose: This study aimed to compare the self-perception of voice at different times and the influence of age, number of infections, underlying diseases, and occupational voice use among individuals with Coronavirus Disease 2019 (COVID-19), with or without a history of hospitalization.
Methods: Data were collected from adults and older adults with COVID-19, treated at a Brazilian Military Hospital between April 2020 and May 2023. The questionnaire was sent by email and a messaging application.
Learning About Classroom Accessibility From a Student-Instructor Partnership.

In this commentary, we, a recent Master of Public Health (MPH) graduate with hearing loss and a course instructor, share what we learned about classroom accessibility while participating in a semester-long qualitative research methods course offered during the COVID-19 pandemic. We complement our reflections on working together with findings from a student field project focused on the lived classroom experiences of graduate students with hearing loss. The field project revealed that students adapted to increased communication challenges in their learning environments without requesting official accommodations due to stigma and a desire to limit their burden on others.

Usher syndrome is a rare autosomal recessive genetic disorder that primarily affects both vision and hearing, manifesting as sensorineural hearing loss and progressive vision loss caused by retinitis pigmentosa. The pathogenesis of retinal degeneration in Usher syndrome is still largely unknown. In this study, a novel Ush2a knockout mouse model was successfully constructed using CRISPR/Cas9 technology.

The stimulation of HC regeneration through exogenous gene delivery represents an ideal therapeutic approach for restoring vestibular function. Overexpression of Atoh1, Pou4f3, and Gfi1 (collectively referred to as APG) has demonstrated efficacy in promoting HC regeneration in the cochlea.

Cochlear inner hair cells (IHCs) and outer hair cells (OHCs) require different transcription factors for their cell fate stabilization and survival, suggesting separate mechanisms are involved. Here, we found that the transcription factor Casz1 was crucial for early IHC fate consolidation and for OHC survival during mouse development. Loss of Casz1 resulted in transdifferentiation of IHCs into OHCs, without affecting OHC production.
