The Effect of Perceived Tinnitus Disturbance on Hope.

Background: Although there are systematic reviews of the effects of tinnitus on quality of life, the relationship of tinnitus to hopefulness has not been examined.

Purpose: The purpose of this study was to determine the relationship between tinnitus distress and hope by comparing the severity of tinnitus to measures of hopefulness. This was done by comparing the Tinnitus Reaction Questionnaire (TRQ) to the following hope scales: the Herth Hope Scale (HHS) and the Herth Hope Index (HHI).

Effectiveness of Television Streaming on Hearing Aid User Performance and Satisfaction in Quiet and in Noise.

Purpose: The purpose of this study was to determine the effectiveness of television (TV) streaming on hearing aid user performance and satisfaction in quiet and in noise.

Method: Twenty experienced hearing aid users were evaluated in quiet and in noise (5 dB SNR) under three hearing aid conditions: hearing aids, streaming with hearing aid microphones attenuated by 6 dB, and streaming with hearing aid microphones muted. The audiovisual Connected Speech Test served as the signal, and the ipsilateral competing message from the Synthetic Sentence Identification-Ipsilateral Competing Message (SSI-ICM) served as the noise.

Effect of Hearing Aid Technology Level on New Hearing Aid Users.

Background: Hearing aid manufacturers offer several different levels of technology that vary in sophistication and cost. It would stand to reason that higher technology hearing aids would provide greater benefit in the daily life of the user; however, research does not support this assumption for all users. Recent research in experienced hearing aid users indicated noise acceptance and satisfaction for speech in a large group were significantly improved when using the premium devices and suggested noise acceptance may be useful when comparing hearing aid technology levels.

Effect of Hearing Aid Technology Level and Individual Characteristics on Listener Outcome Measures.

Purpose The purpose of the study was to determine the effect of hearing aid technology level on listener outcome measures. In addition, we aimed to determine if individual characteristics such as noise acceptance and the demands of the listening environment impacted performance and preference. Method A repeated-measures, single-blinded research design was utilized.

TGF-beta-dependent pathogenesis of mitral valve prolapse in a mouse model of Marfan syndrome.

Mitral valve prolapse (MVP) is a common human phenotype, yet little is known about the pathogenesis of this condition. MVP can occur in the context of genetic syndromes, including Marfan syndrome (MFS), an autosomal-dominant connective tissue disorder caused by mutations in fibrillin-1. Fibrillin-1 contributes to the regulated activation of the cytokine TGF-beta, and enhanced signaling is a consequence of fibrillin-1 deficiency.
