  • Examining the effects of an Educational Person-centered Intervention on Compensatory Strategies (EPICS) in older adults living with frailty: A mixed-methods pilot trial

    by Véronique Provencher, Monia D’aMours, Hélène Carbonneau, Mélanie Levasseur, Valérie Poulin, Johanne Filiatrault, Natasa Obradovic, Louise Drouin, Dominique Giroux

    This study aimed to explore effects of a two-session Educational Person-centered Intervention on Compensatory Strategies (EPICS) designed to increase knowledge of strategies, reduce barriers, and improve accomplishment of meaningful leisure activities (MLA) and well-being in older adults living with frailty. Using a double-blind concurrent mixed-methods design, 36 community-dwelling older adults were assigned to the experimental (EPICS) or control (friendly visits) group through a covariate adaptive randomization. Questionnaires were administered prior to the intervention and ± two months post-intervention. Individual semi-structured interviews conducted at the end of the study furthered the authors’ understanding of the effects of the intervention. Quantitative analysis revealed significant increase in knowledge of compensatory strategies and reduction of barriers for the experimental group only. Qualitative analysis (purposive sample, n = 8) showed enhanced well-being and self-activation. Discussions about barriers to accomplishment may be sufficient to trigger self-activation in someolder adults living with frailty to improve participation in MLA and well-being.

    Mobile Videoconferencing for Occupational Therapists’ Assessments of Patients’ Home Environments Prior to Hospital Discharge: Mixed Methods Feasibility and Comparative Study

    by Karine Latulippe, Dominique Giroux, Manon Guay, Dahlia Kairy, Claude Vincent, Katia Boivin, Ernesto Morales, Natasa Obradovic, Véronique Provencher

    Background: Occupational therapists who work in hospitals need to assess patients’ home environment in preparation for hospital discharge in order to provide recommendations (eg, technical aids) to support their independence and safety. Home visits increase performance in everyday activities and decrease the risk of falls; however, in some countries, home visits are rarely made prior to hospital discharge due to the cost and time involved. In most cases, occupational therapists rely on an interview with the patient or a caregiver to assess the home. The use of videoconferencing to assess patients’ home environments could be an innovative solution to allow better and more appropriate recommendations. Objective: The aim of this study was (1) to explore the added value of using mobile videoconferencing compared with standard procedure only and (2) to document the clinical feasibility of using mobile videoconferencing to assess patients’ home environments. Methods: Occupational therapists assessed home environments using, first, the standard procedure (interview), and then, videoconferencing (with the help of a family caregiver located in patients’ homes, using an electronic tablet). We used a concurrent mixed methods design. The occupational therapist's responsiveness to telehealth, time spent on assessment, patient’s occupational performance and satisfaction, and major events influencing the variables were collected as quantitative data. The perceptions of occupational therapists and family caregivers regarding the added value of using this method and the nature of changes made to recommendations as a result of the videoconference (if any) were collected as qualitative data, using questionnaires and semistructured interviews. Results: Eight triads (6 occupational therapists, 8 patients, and 8 caregivers) participated. The use of mobile videoconferencing generally led occupational therapists to modify the initial intervention plan (produced after the standard interview). Occupational therapists and caregivers perceived benefits in using mobile videoconferencing (eg, the ability to provide real-time comments or feedback), and they also perceived disadvantages (eg, videoconferencing requires additional time and greater availability of caregivers). Some occupational therapists believed that mobile videoconferencing added value to assessments, while others did not. Conclusions: The use of mobile videoconferencing in the context of hospital discharge planning has raised questions of clinical feasibility. Although mobile videoconferencing provides multiple benefits to hospital discharge, including more appropriate occupational therapist recommendations, time constraints made it more difficult to perceive the added value. However, with smartphone use, interdisciplinary team involvement, and patient participation in the videoconference visit, mobile videoconferencing can become an asset to hospital discharge planning.

    Understanding the Benefits, Challenges, and the Role of Pet Ownership in the Daily Lives of Community-Dwelling Older Adults: A Case Study

    by Nataša Obradović, Émilie Lagueux, Karine Latulippe, Véronique Provencher

    Human–animal interactions may positively impact the health and well-being of older adults. Considering about one third of community-dwelling older adults report owning a pet, better understanding the benefits, challenges, and the role of pet ownership may help support the relationships between older adults and their pets. This case study aims to better understand the role of pet ownership in the daily lives of older adults and explore the benefits and the challenges of owning a pet for this population. Interviews were conducted with Violet, a 77-year-old dog owner and her healthcare provider. Qualitative data were analyzed by two evaluators and validated by the participants. Both participants agree that the benefits outweigh the challenges for both the older adult and her pet. The benefits and challenges were the following: Violet, taking care of her dog (Jack), (1) could provide Violet with a sense of safety and positively influence her mood; (2) may introduce a slight fall risk; (3) includes financial costs to consider. Ensuring Jack’s well-being is important for Violet and her dog benefits from Violet’s continual presence and care. The findings suggest that improving the fit between characteristics of the owner and their pet may support the meaningful role of pet ownership within the context of aging-in-place.

    Mobile Videoconferencing for Occupational Therapists’ Assessments of Patients’ Home Environments Prior to Hospital Discharge: Mixed Methods Feasibility and Comparative Study (Preprint)

    Analysis of Globodera rostochiensis effectors reveals conserved functions of SPRYSEC proteins in suppressing and eliciting plant immune responses

    by Shawkat Ali, Maxime Magne, Shiyan Chen, Natasa Obradovic, Lubna Jamshaid, Xiaohong Wang, Guy Bélair, Peter Moffett

    Potato cyst nematodes (PCNs), including Globodera rostochiensis (Woll.), are important pests of potato. Plant parasitic nematodes produce multiple effector proteins, secreted from their stylets, to successfully infect their hosts. These include proteins delivered to the apoplast and to the host cytoplasm. A number of effectors from G. rostochiensis predicted to be delivered to the host cytoplasm have been identified, including several belonging to the secreted SPRY domain (SPRYSEC) family. SPRYSEC proteins are unique to members of the genera Globodera and have been implicated in both the induction and the repression of host defense responses. We have tested the properties of six different G. rostochiensis SPRYSEC proteins by expressing them in Nicotiana benthamiana and N. tabacum. We have found that all SPRYSEC proteins tested are able to suppress defense responses induced by NB-LRR proteins as well as cell death induced by elicitors, suggesting that defense repression is a common characteristic of members of this effector protein family. At the same time, GrSPRYSEC-15 elicited a defense response in N. tabacum, and tobacco was found to be resistant to a virus expressing GrSPRYSEC-15. These results suggest that SPRYSEC proteins may possess characteristics that allow them to be recognized by the plant immune system.
