New perspectives on counselling in audiological habilitation/rehabilitation

Conversations about mental illness and health in adult audiological rehabilitation

OBJECTIVE

To understand the nature of mental health discussions in audiological rehabilitation, specifically, the types of conversations, when and how they are initiated, and the participant factors associated with discussing mental health.

DESIGN

A cross-sectional descriptive survey including quantitative (multiple choice) and qualitative (free-text) questions regarding mental health discussions between audiologists and clients.

STUDY SAMPLE

A convenience sample of 118 Australian audiologists working in adult audiological rehabilitation.

RESULTS

The majority of participants (95.8%) reported having engaged in discussions with clients about mental illness and health at some point throughout their career. The frequency of these discussions varied across participants: 7% rarely discuss, 50% discuss occasionally, 30% discuss with about half their clients and 13% have discussions with most clients. Many participants (85.6%) reported that clients would initiate these conversations, most often via disclosing the impacts of hearing loss on clients' lives.

CONCLUSIONS

Most audiologists will encounter clients with mental health concerns, and many will engage in conversations about psychological symptoms, therefore, training audiologists to recognise and address verbal and non-verbal cues regarding mental health may help to promote person-centred care and potentially improve outcomes.

Guidelines for Best Practice in the Audiological Management of Adults with Severe and Profound Hearing Loss

Individuals with severe to profound hearing loss are likely to present with complex listening needs that require evidence-based solutions. This document is intended to inform the practice of hearing care professionals who are involved in the audiological management of adults with a severe to profound degree of hearing loss and will highlight the special considerations and practices required to optimize outcomes for these individuals.

Parent-of-Origin-Effect rough endosperm Mutants in Maize

Parent-of-origin-effect loci have non-Mendelian inheritance in which phenotypes are determined by either the maternal or paternal allele alone. In angiosperms, parent-of-origin effects can be caused by loci required for gametophyte development or by imprinted genes needed for seed development. Few parent-of-origin-effect loci have been identified in maize (Zea mays) even though there are a large number of imprinted genes known from transcriptomics. We screened rough endosperm (rgh) mutants for parent-of-origin effects using reciprocal crosses with inbred parents. Six maternal rough endosperm (mre) and three paternal rough endosperm (pre) mutants were identified with three mre loci mapped. When inherited from the female parent, mre/+ seeds reduce grain fill with a rough, etched, or pitted endosperm surface. Pollen transmission of pre mutants results in rgh endosperm as well as embryo lethality. Eight of the mutants had significant distortion from the expected one-to-one ratio for parent-of-origin effects. Linked markers for mre1, mre2, and mre3 indicated that the mutant alleles have no bias in transmission. Histological analysis of mre1, mre2, mre3, and pre*-949 showed altered timing of starch grain accumulation and basal endosperm transfer cell layer (BETL) development. The mre1 locus delays BETL and starchy endosperm development, while mre2 and pre*-949 cause ectopic starchy endosperm differentiation. We conclude that many parent-of-origin effects in maize have incomplete penetrance of kernel phenotypes and that there is a large diversity of endosperm developmental roles for parent-of-origin-effect loci.
