Abstract
INTRODUCTION: Cochlear implantation is an increasingly common procedure in the treatment of severe to profound sensorineural hearing loss (SNHL) in children and adults. It is often performed as a day-case procedure. The major drive towards day-case surgery has been from a logistical, economical and societal perspective, but we also speculate that the patient's quality of life (QoL) is at least equal to inpatient surgery if not increased as a result of rapid discharge and rehabilitation. Even though cochlear implantation seems well suited to a day-case approach and this even seems to be common practice in some countries, evidence is scarce and of low quality to guide us towards the preferred treatment option.
METHODS AND ANALYSIS: A single-centre, non-blinded, randomised, controlled trial was designed to (primarily) investigate the effect on general QoL of day-case cochlear implantation compared to inpatient cochlear implantation and (secondarily) the effect of both methods on (subjective) hearing improvement, disease-specific QoL, tinnitus, vertigo and cost-effectiveness. 30 adult patients with severe to profound bilateral postlingual SNHL who are eligible for unilateral cochlear implantation will be randomly assigned to either the day-case or inpatient treatment group. The outcome measures will be assessed using auditory evaluations, questionnaires (preoperatively, at 1-week, 3-week, 3-month and 1-year follow-up) and costs diaries (weekly during the first month postoperatively, after which once in a month until 1-year follow-up). Preoperative and postoperative outcomes will be compared. The difference in costs and benefit will be represented using the incremental cost utility/effectiveness ratio. The analyses will be carried out on an intention-to-treat basis.
ETHICS AND DISSEMINATION: This research protocol was approved by the Institutional Review Board of the UMC Utrecht (NL45590.041.13; V.5, November 2015). The trial results will be disseminated through peer-reviewed medical journals and presented at scientific conferences.

Time-Varying Distortions of Binaural Information by Bilateral Hearing Aids: Effects of Nonlinear Frequency Compression.
Trends Hear. 2016 Oct 3;20:
Authors: Brown AD, Rodriguez FA, Portnuff CD, Goupell MJ, Tollin DJ
Abstract
In patients with bilateral hearing loss, the use of two hearing aids (HAs) offers the potential to restore the benefits of binaural hearing, including sound source localization and segregation. However, existing evidence suggests that bilateral HA users' access to binaural information, namely interaural time and level differences (ITDs and ILDs), can be compromised by device processing. Our objective was to characterize the nature and magnitude of binaural distortions caused by modern digital behind-the-ear HAs using a variety of stimuli and HA program settings. Of particular interest was a common frequency-lowering algorithm known as nonlinear frequency compression, which has not previously been assessed for its effects on binaural information. A binaural beamforming algorithm was also assessed. Wide dynamic range compression was enabled in all programs. HAs were placed on a binaural manikin, and stimuli were presented from an arc of loudspeakers inside an anechoic chamber. Stimuli were broadband noise bursts, 10-Hz sinusoidally amplitude-modulated noise bursts, or consonant-vowel-consonant speech tokens. Binaural information was analyzed in terms of ITDs, ILDs, and interaural coherence, both for whole stimuli and in a time-varying sense (i.e., within a running temporal window) across four different frequency bands (1, 2, 4, and 6 kHz). Key findings were: (a) Nonlinear frequency compression caused distortions of high-frequency envelope ITDs and significantly reduced interaural coherence. (b) For modulated stimuli, all programs caused time-varying distortion of ILDs. (c) HAs altered the relationship between ITDs and ILDs, introducing large ITD-ILD conflicts in some cases. Potential perceptual consequences of measured distortions are discussed.

A tool for assessing case history and feedback skills in audiology students working with simulated patients.
Int J Audiol. 2016 Dec;55(12):765-774
Authors: Hughes J, Wilson WJ, MacBean N, Hill AE
Abstract
OBJECTIVE: To develop a tool for assessing audiology students taking a case history and giving feedback with simulated patients (SP).
DESIGN: Single observation, single group design.
STUDY SAMPLE: Twenty-four first-year audiology students, five simulated patients, two clinical educators, and three evaluators.
RESULTS: The Audiology Simulated Patient Interview Rating Scale (ASPIRS) was developed consisting of six items assessing specific clinical skills, non-verbal communication, verbal communication, interpersonal skills, interviewing skills, and professional practice skills. These items are applied once for taking a case history and again for giving feedback. The ASPIRS showed very high internal consistency (α = 0.91-0.97; mean inter-item r = 0.64-0.85) and fair-to-moderate agreement between evaluators (29.2-54.2% exact and 79.2-100% near agreement; κweighted up to 0.60). It also showed fair-to-moderate absolute agreement amongst evaluators for single evaluator scores (intraclass correlation coefficient [ICC] r = 0.35-0.59) and substantial consistency of agreement amongst evaluators for three-evaluator averaged scores (ICC r = 0.62-0.81). Factor analysis showed the ASPIRS' 12 items fell into two components, one containing all feedback items and one containing all case history items.
CONCLUSION: The ASPIRS shows promise as the first published tool for assessing audiology students taking a case history and giving feedback with an SP.

Collaboration, trouble and repair in multiparty interactions involving couples with dementia or aphasia.
Int J Speech Lang Pathol. 2016 Oct 4;:1-11
Authors: Samuelsson C, HydéN LC
Abstract
PURPOSE: The aim of the present study was to identify problems with communication with persons with aphasia and persons with dementia in a collaborative interview setting with their significant others. In particular, to compare interactional practices used in order to resolve problems caused by specific symptoms.
METHOD: Five persons with aphasia and five persons with dementia and their spouses participated in the study. Interviews were carried out couple by couple, and the interviews had a task-oriented character. The interviews were video and audio recorded. All interviews were transcribed. From the transcriptions categorisations according to previous literature were made.
RESULT: The results demonstrated that repair sequences were frequent in interaction involving people with aphasia (PWA), and even more so in interaction involving persons with dementia (PWD). In general, it was the PWA/PWD that initiated the repair sequence more often than the spouse, thus keeping the general rule of a preference for self-initiated repair compared to other-initiated repair.
CONCLUSION: The active involvement of the conversational partners in trouble solving sequences in interaction with PWA/PWD demonstrated in the present study indicates that the interactional style of the conversational partner to PWA/PWD important. This implies that conversation partner training programmes would be useful both for PWA and for PWD.
