The cartilage-conduction hearing aid (CC-HA) is a new hearing device that is suitable for use in patients with conductive hearing loss. It has been 5 years since the introduction of the CC-HA. Although the number of users has increased, the CC-HA is not yet widely known. This study examines the effects of CC-HA on patients with conductive hearing loss and investigates factors that affect the willingness to use the device by comparing purchasers and non-purchasers of CC-HA in patients with unilateral conductive hearing loss. Eight patients had bilateral conductive hearing loss, and 35 had unilateral conductive hearing loss. Each patient underwent sound field tests and speech audiometry, and the effects of the CC-HA were compared with those of conventional bone conduction hearing aids (BC-HA). In patients with bilateral conductive hearing loss, the CC-HA was non-inferior to BC-HA. The CC-HA improved the hearing thresholds and speech recognition in patients with unilateral conductive hearing loss. Moreover, in patients with unilateral conductive hearing loss, experiencing the effect of wearing the CC-HA under conditions such as putting noise in the better ear could affect patients' willingness to use the CC-HA.

University of Virginia School of Nursing, Charlottesville, Virginia.
Background: Persons with disabilities are at higher risk of experiencing intimate partner violence (IPV) during the perinatal period than persons without disabilities. Although screening for IPV during the perinatal period is recommended by many organizations, little is known about screening rates for IPV by disability status.
Methods: Our objective was to compare rates of IPV screening during the perinatal period among persons with and without disabilities in the United States.
Background: Noise-induced hearing loss (NIHL) in children is a growing public health concern due to increased exposure to high noise levels in various environments. Early intervention is crucial to prevent long-term developmental and social impacts. This study evaluates the effectiveness of earmuffs as a protective intervention in managing NIHL in children.

Background: Noise sources in paediatric dental offices include machinery and children's cries and screams. Although the presence of occupational noise-induced hearing loss (ONIHL) among dental operators is established, preventive measures such as ear protection devices (EPDs) are not frequently employed as prophylactic intervention. The primary aim of this study was to quantitatively assess the noise levels in paediatric dental clinics and to qualitatively evaluate the operators' perception of noise with and without the use of EPDs.

Background: With the aging of the population, the deterioration of visual and auditory functions amongst the elderly has attracted much attention. Age-related hearing loss (ARHL) and age-related macular degeneration (AMD) are common eye and ear diseases that seriously affect the quality of life of elderly population.
Methods: This study utilised a whole cohort sampling method, with a total of 713 participants aged 50 years and older in the community from June 2022 to October 2023, resulting in the inclusion of 620 participants.
