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.

Psychologically Informed Practice in Audiological Rehabilitation: Audiologist Perceived Barriers, Facilitators, and Preparedness.

OBJECTIVES: Psychological factors, such as mental illness, mental health, attitudes, emotions, and coping styles, are known to impact the success of audiological rehabilitation. However, evidence suggests that audiologists are not sufficiently addressing client psychological factors. Psychologically informed practice, implemented in other healthcare professions, is a framework that guides clinicians in addressing both the physical and psychological factors of a condition throughout rehabilitation. Psychologically informed practice may also be an appropriate framework to improve client outcomes in audiology. The objectives of this study were (1) to determine the barriers and facilitators to audiologists addressing client mental health, psychological symptoms, emotions, and feelings, and (2) to determine audiologists' preparedness and willingness to implement aspects of psychologically informed practice in audiological rehabilitation. DESIGN: A cross-sectional survey was conducted with a convenience sample of 118 Australian clinical audiologists (83.1%, n = 98 female) working in adult audiological rehabilitation. RESULTS: Most participants (91.5%) reported at least one barrier to discussing mental health with clients, with the most common being insufficient knowledge and skills in mental health (39.8%). Applying the COM-B model of behavior change, audiologists reported that factors related to motivation were primarily facilitators, and factors related to opportunity (e.g., lack of time) and capabilities (e.g., insufficient knowledge) were barriers to discussing client mental health. Many participants (83.1%) reported willingness to incorporate a clear protocol, including when and how to refer to psychological services, within audiological rehabilitation. CONCLUSIONS: Audiologists were generally motivated to incorporate psychologically informed practice into audiological rehabilitation; however, lack of knowledge and organizational barriers would need to be overcome. The insights gained in this study provide a foundation for developing a viable approach to psychologically informed practice, which may ultimately encourage audiologists to engage in person-centered care more actively.

The CAZyome of Phytophthora spp.: a comprehensive analysis of the gene complement coding for carbohydrate-active enzymes in species of the genus Phytophthora.

BACKGROUND: Enzymes involved in carbohydrate metabolism include Carbohydrate esterases (CE), Glycoside hydrolases (GH), Glycosyl transferases (GT), and Polysaccharide lyases (PL), commonly referred to as carbohydrate-active enzymes (CAZymes). The CE, GH, and PL superfamilies are also known as cell wall degrading enzymes (CWDE) due to their role in the disintegration of the plant cell wall by bacterial and fungal pathogens. In Phytophthora infestans, penetration of the plant cells occurs through a specialized hyphal structure called appressorium; however, it is likely that members of the genus Phytophthora also use CWDE for invasive growth because hyphal forces are below the level of tensile strength exhibited by the plant cell wall. Because information regarding the frequency and distribution of CAZyme coding genes in Phytophthora is currently unknown, we have scanned the genomes of P. infestans, P. sojae, and P. ramorum for the presence of CAZyme-coding genes using a homology-based approach and compared the gene collinearity in the three genomes. In addition, we have tested the expression of several genes coding for CE in cultures grown in vitro. RESULTS: We have found that P. infestans, P. sojae and P. ramorum contain a total of 435, 379, and 310 CAZy homologs; in each genome, most homologs belong to the GH superfamily. Most GH and PL homologs code for enzymes that hydrolyze substances present in the pectin layer forming the middle lamella of the plant cells. In addition, a significant number of CE homologs catalyzing the deacetylation of compounds characteristic of the plant cell cuticle were found. In general, a high degree of gene location conservation was observed, as indicated by the presence of sequential orthologous pairs in the three genomes. Such collinearity was frequently observed among members of the GH superfamily. On the other hand, the CE and PL superfamilies showed less collinearity for some of their putative members. Quantitative PCR experiments revealed that all genes are expressed in P. infestans when this pathogen grown in vitro. However, the levels of expression vary considerably and are lower than the expression levels observed for the constitutive control. CONCLUSIONS: In conclusion, we have identified a highly complex set of CAZy homologs in the genomes of P. infestans, P. sojae, and P. ramorum, a significant number of which could play roles critical for pathogenicity, by participating in the degradation of the plant cell wall.

Experiences of Hearing Loss and Audiological Rehabilitation for Older Adults With Comorbid Psychological Symptoms: A Qualitative Study.

Purpose There is a well-established relationship between hearing loss and psychological symptoms. To ensure audiological rehabilitation is provided appropriately for older adults with comorbid psychological symptoms, a greater understanding of their preferences and experiences is needed. This study sought to understand experiences of hearing loss and audiological rehabilitation from the perspective of older adults with comorbid psychological symptoms (e.g., depression, anxiety, psychosis). Design A qualitative study using in-depth semistructured interviews was conducted with older adults who had attended audiological rehabilitation within the last year and scored above established cutoffs on measures of depression, anxiety, and psychosis. A thematic analysis generated themes that related to participants' experiences of hearing loss and audiological rehabilitation. Results Participants included 14 older adults (eight men and six women) with an average age of 70.5 years (SD = 4.45, range: 64-80) who received hearing aids or a cochlear implant. Three major themes emerged from the analysis of participant interviews. "The cumulative impact of hearing loss and psychological symptoms" theme describes the two-way, additive relationship between hearing ability and psychological symptoms. "The experience of loss throughout hearing loss and audiological rehabilitation" captures subjective losses, the impact they have, and how participants cope with them. In contrast, "The experience of gain throughout hearing loss and audiological rehabilitation" describes the participants' reported gains, their related impacts, and coping strategies. Conclusions The experiences of participants revealed that the presence of comorbid psychological symptoms can influence the experience of hearing loss and audiological rehabilitation. These findings have implications for how audiological rehabilitation is provided to ensure optimal outcomes for adults with hearing loss and comorbid psychological symptoms.

Knowledge, Beliefs, and Practices of Australian Audiologists in Addressing the Mental Health Needs of Adults With Hearing Loss.

Purpose Emotional and mental health is essential to overall health, but there has been little research on how to approach emotional and mental health in the audiology setting. This study provides a preliminary investigation into the current knowledge, beliefs, and practices of Australian audiologists in addressing the emotional and mental health needs of adults with hearing loss. Method A 22-item survey using open- and closed-ended questions was completed by 95 Australian audiologists using a cross-sectional study design. Results Two thirds of audiologists described being underconfident and lacking the skills required to provide emotional support to people with hearing loss. Barriers to delivering emotional support included feeling out of their depth (56.6%), time/caseload pressures (55.3%), and the perception that the provision of emotional support was not within an audiologist's scope of practice (31.6%). Audiologists described a desire to refer clients to mental health professionals yet highlighted significant barriers, including not knowing who to refer to (54.7%), when to make a referral (49.3%), or how to make a referral (38.6%). Audiologists overwhelmingly (96%) indicated that they would like to develop their knowledge and skills associated with the provision of emotional and mental health support in the audiological setting. Conclusion Knowledge, skills, and time were identified as the key areas that require attention in order to allow audiologists to address the emotional and mental health needs of adults with hearing loss.

Maternal hematopoietic TNF, via milk chemokines, programs hippocampal development and memory.

Tumor necrosis factor α (TNF) is a proinflammatory cytokine with established roles in host defense and immune system organogenesis. We studied TNF function and found a previously unidentified physiological function that extends its effect beyond the host into the developing offspring. A partial or complete maternal TNF deficit, specifically in hematopoietic cells, resulted in reduced milk levels of the chemokines IP-10, MCP-1, MCP-3, MCP-5 and MIP-1ß, which in turn augmented offspring postnatal hippocampal proliferation, leading to improved adult spatial memory in mice. These effects were reproduced by the postpartum administration of a clinically used anti-TNF agent. Chemokines, fed to suckling pups of TNF-deficient mothers, restored both postnatal proliferation and spatial memory to normal levels. Our results identify a TNF-dependent 'lactrocrine' pathway that programs offspring hippocampal development and memory. The level of ambient TNF is known to be downregulated by physical activity, exercise and adaptive stress. We propose that the maternal TNF-milk chemokine pathway evolved to promote offspring adaptation to post-weaning environmental challenges and competition.
