E-learning modules to enhance student nurses' perceptions of older people: a single group pre-post quasi-experimental study.

OBJECTIVES: To examine whether e-learning activities on cognitive impairment (CI), continence and mobility (CM) and understanding and communication (UC) improve student nurses' knowledge and attitudes in the care of older adults. METHODS: A quasi-experimental single group pre-post-test design was used. We included 299 undergraduate nursing students for the CI module, 304 for the CM module, and 313 for the UC module. We administered knowledge quizzes, Likert scales, and a feedback survey to measure student nurses' knowledge, ageist beliefs, and feedback on the modules respectively. RESULTS: Participants demonstrated significantly more knowledge and reduced ageist attitudes following the e-learning activities. CONCLUSIONS: Findings suggest that e-learning activities on cognitive impairment, continence and mobility, and understanding and communication improve knowledge and reduce ageist attitudes among nursing students.

Unaltered hepatic wound healing response in male rats with ancestral liver injury.

The possibility that ancestral environmental exposure could result in adaptive inherited effects in mammals has been long debated. Numerous rodent models of transgenerational responses to various environmental factors have been published but due to technical, operational and resource burden, most still await independent confirmation. A previous study reported multigenerational epigenetic adaptation of the hepatic wound healing response upon exposure to the hepatotoxicant carbon tetrachloride (CCl4) in male rats. Here, we comprehensively investigate the transgenerational effects by repeating the original CCl4 multigenerational study with increased power, pedigree tracing, F2 dose-response and suitable randomization schemes. Detailed pathology evaluations do not support adaptive phenotypic suppression of the hepatic wound healing response or a greater fitness of F2 animals with ancestral liver injury exposure. However, transcriptomic analyses identified genes whose expression correlates with ancestral liver injury, although the biological relevance of this apparent transgenerational transmission at the molecular level remains to be determined. This work overall highlights the need for independent evaluation of transgenerational epigenetic inheritance paradigms in mammals.

Improving practicing nurses' knowledge of the cognitive impairment, continence, and mobility needs of older people.

OBJECTIVES: To test if two e-learning modules - one on cognitive impairment, and one on continence and mobility - in older people would improve the knowledge of nurse members from the Canadian Gerontological Nurses Association and College of Licensed Practical Nurses of Alberta. METHODS: A pre-post-test design was used to test 88 nurses' knowledge of cognitive impairment and 105 nurses' knowledge of continence and mobility and their perceptions of how the modules contributed to their learning. RESULTS: There was a statistically significant increase in practicing nurses' knowledge about cognitive impairment (0.68 increase), continence (2.30 increase), and its relationship to mobility. Nurses' self-report on the feedback survey demonstrated increases in knowledge, confidence, and perceptions about older people. CONCLUSION: These results suggest the modules have strong potential to enhance practicing nurses' knowledge about cognitive impairment, continence, and mobility.

Improving practicing nurses' knowledge and perceptions of older people: a quasi-experimental study.

OBJECTIVES: This study aimed to determine if an e-learning module about understanding and communicating with older people can improve practicing nurses' ageist perceptions about older people. METHODS: We used a quasi-experimental pre-post-test design. Participants completed a 13-item Ambivalent Ageism Scale before and after completing the Understanding and Communicating with Older People e-learning module as well as a Likert-style feedback survey with the option for written feedback on an open-ended question. RESULTS: Pre-post-test comparisons indicated a statistically significant decrease in ageist attitudes and self-reported increases in knowledge and confidence in working with older people. Qualitative analysis of written feedback revealed that most participants felt the module enhanced their understanding of older people. CONCLUSIONS: The e-learning activity has the potential to improve practicing nurses' knowledge and perceptions about working with older people and is likely to be associated with better patient-level outcomes.

Short report: Vaccine attitudes in the age of COVID-19 for a population of children with mitochondrial disease.

BACKGROUND: Children with developmental disabilities are vulnerable to morbidity associated with COVID-19. AIMS: To understand attitudes toward routine childhood vaccinations versus the COVID-19 vaccine in a population of families affected by mitochondrial disease (MtD), a form of developmental disability. METHODS AND PROCEDURES: An online survey was administered via several advocacy groups for children with MtD. OUTCOMES AND RESULT: Eighty-six percent of families reported being up to date with the childhood vaccine schedule and seventy percent reported that their affected child receives the annual flu shot. However, only fifty percent reported that the benefits of the COVID-19 vaccine outweighed the risk for their affected child. One quarter of families expressed concern that their child may become sick or deteriorate after the COVID-19 vaccine. In comparison to other routine childhood vaccines, families expressed less confidence in the COVID-19 vaccine. CONCLUSIONS AND IMPLICATIONS: Families affected by this population of developmental disabilities are more comfortable with the vaccines included in the routine childhood immunization schedule than with the newly introduced COVID-19 vaccine, even despite this group's vulnerability.

Wearable multimodal sensors for the detection of behavioral and psychological symptoms of dementia using personalized machine learning models.

Introduction: Behavioral and psychological symptoms of dementia (BPSD) signal distress or unmet needs and present a risk to people with dementia and their caregivers. Variability in the expression of these symptoms is a barrier to the performance of digital biomarkers. The aim of this study was to use wearable multimodal sensors to develop personalized machine learning models capable of detecting individual patterns of BPSD. Methods: Older adults with dementia and BPSD (n = 17) on a dementia care unit wore a wristband during waking hours for up to 8 weeks. The wristband captured motion (accelerometer) and physiological indicators (blood volume pulse, electrodermal activity, and skin temperature). Agitation or aggression events were tracked, and research staff reviewed videos to precisely annotate the sensor data. Personalized machine learning models were developed using 1-minute intervals and classifying the presence of behavioral symptoms, and behavioral symptoms by type (motor agitation, verbal aggression, or physical aggression). Results: Behavioral events were rare, representing 3.4% of the total data. Personalized models classified behavioral symptoms with a median area under the receiver operating curve (AUC) of 0.87 (range 0.64-0.95). The relative importance of the different sensor features to the predictive models varied both by individual and behavior type. Discussion: Patterns of sensor data associated with BPSD are highly individualized, and future studies of the digital phenotyping of these behaviors would benefit from personalization.

Beyond instrumental support: Mobile application use by family caregivers of persons living with dementia.

In recent years, there has been a rapid increase in technology use in dementia caregiving, particularly the use of mobile applications (apps) which are highly accessible, cost-effective and intuitive. Yet, little is known about the experiences of family caregivers of persons living with dementia who use apps to support caregiving activities. This is of particular concern given that limited understandings of the user experience in designing technology have often led to end-users experiencing barriers in technology adoption and use. Using a qualitative descriptive approach, the purpose of the study was to explore the experiences of family caregivers of persons living with dementia on using apps in their caregiving roles. A purposive sample of five family caregivers in Ontario, Canada participated in two interviews each, with the second interview informed by photo-elicitation methods. Thematic analysis of the collected data revealed a central overarching theme, Connecting to support through apps in my, your and our lives, which explicated how apps played an important role in the lives of the caregiver, the care recipient and both together as a dyad. Three core themes also emerged: Adapting apps to meet individual needs of the dyad, Minimising the impact of the condition on the person and the family and Determining the effectiveness of apps. The findings highlighted that the value of apps extends beyond their mere functionality and their ability to help with care provision as they are also able to promote richer interpersonal connections, enhance personhood and sustain family routines. This research advances our understanding of the impact of app use in caregiving and provides direction for future research, policy, education, practice and app development.

Implementing Gentle Persuasive Approaches dementia education for staff on in-patient medicine units: A program evaluation.

Older adults with dementia, when hospitalised, frequently experience responsive behaviours. Staff struggle to manage responsive behaviours without specific education. We aimed to enhance staff knowledge and confidence with care for older adults with dementia and responsive behaviours on medicine units at a Canadian hospital. An online dementia education program was disseminated to staff as part of a broader quality improvement project. Gentle Persuasive Approaches (GPA) encourages staff to reframe responsive behaviours as self-protective expressions of unmet needs and learn to assess their meaning. Participants completed online quantitative and qualitative measures of self-efficacy, competence and knowledge in dementia care at three times: immediate pre-, immediate post- and six to eight weeks post-GPA eLearning. Immediately post-GPA, participants showed significant increases relative to baseline in dementia care self-efficacy, competence and knowledge. Self-efficacy scores increased further eight weeks post-GPA. Before GPA, few participants described dementia-specific strategies for de-escalating a patient's agitation. Eight weeks post-GPA, participants described application of tailored, person-centred, non-pharmacological interventions and successful application of GPA strategies. GPA eLearning strengthened staff preparedness to interact with older adults experiencing responsive behaviours, thus enhancing their care.

Risk mitigation behaviors to prevent infection in the mitochondrial disease community during the COVID-19 pandemic.

BACKGROUND: A challenge during the COVID-19 pandemic has been widespread adherence to risk-reducing behaviors. Individuals with mitochondrial disease (MtD) are special population with an increased risk of morbidity associated with infection. PURPOSE: To measure risk mitigation behaviors (RMBs) in families affected by MtD and identify factors that may influence these behaviors. METHODS: An online questionnaire was distributed in April and June 2020. Individuals with MtD or their caregivers completed the survey. RESULTS: We received 529 eligible responses with n = 312 completing all questions for our multivariate regression model. The most common RMBs were increased hand washing (96%), social distancing (94%), and avoiding public gatherings (93%). Higher numbers of recent healthcare visits (b = 0.62, p < 0.05) and expressed fear of the MtD patient contracting COVID-19 (b = 0.92, p < 0.05) were associated with more RMBs. Living in a rural community (b = -0.99,p < 0.05) and a history of COVID-19 testing (b = -2.14,p < 0.01) were associated with fewer RMBs. CONCLUSIONS: Our results suggest that during the COVID-19 pandemic, families affected by MtD have near universal adherence to basic RMBs. This may be motivated by fear of the severe morbidity associated with infection in MtD. Patients with frequent healthcare visits may be sicker and therefore take more precautions. Living in a rural community may also impact these behaviors. People who practice fewer RMBs may be more likely to seek testing. Our findings may generalize to other chronic diseases.

Dementia and sexuality in long-term care: Incompatible bedfellows?

Despite the recognized benefits of sexual expression and its importance in the lives of people living with dementia, research demonstrates that there are multiple barriers to its positive expression (e.g., expression that is pleasurable and free of coercion, discrimination, and violence) in RLTC homes. These barriers constitute a form of discrimination based on age and ability, and violate the rights of persons living with dementia to dignity, autonomy, and participation in everyday life and society. Drawing on a human rights approach to dementia and sexual expression, we explored the experiences of diverse professionals, family members, and persons living with dementia with explicit attention to the ways in which macro-level dynamics are influencing the support, or lack thereof, for sexual expression at the micro level. Focus groups and in-depth interviews were conducted with 27 participants, and the collected data were analyzed thematically. While all participants acknowledged that intimacy and sexual expression of persons living with dementia should be supported, rarely is such expression supported in practice. Micro-level factors included negative attitudes of professionals toward sexual expression by persons living with dementia, their discomfort with facilitating intimacy and sexual expression in the context of their professional roles, their anxieties regarding potential negative reactions from family members, and concerns about sanctions for failing to prevent abuse. In our analysis, we importantly trace these micro-level factors to macro-level factors. The latter include the cultural stigma associated with dementia, ageism, ableism, and erotophobia, all of which are reproduced in, and reinforced by, professionals' education, as well as legal and professional standards that exclusively focus on managing and safeguarding residents from abuse. Our analysis demonstrates a complexity that has enormous potential to inform future research that is critically needed for the development of educational initiatives and to promote policy changes in this area.

Awakening Canadians to ageism: a study protocol.

BACKGROUND: Making fun of growing older is considered socially acceptable, yet ageist humour reinforces negative stereotypes that growing old is linked with physical and mental deterioration, dependence, and less social value. Such stereotypes and discrimination affect the wellbeing of older people, the largest demographic of Canadians. While ageism extends throughout professions and social institutions, we expect nurses-the largest and most trusted group of healthcare professionals-to provide non-ageist care to older people. Unfortunately, nurses working with older people often embrace ageist beliefs and nursing education programs do not address sufficient anti-ageism content despite gerontological nursing standards and competencies. METHODS: To raise awareness of ageism in Canada, this quasi-experimental study will be supported by partnerships between older Canadians, advocacy organizations, and academic gerontological experts which will serve as an advisory group. The study, guided by social learning theory, will unfold in two parts. In Phase 1, we will use student nurses as a test case to determine if negative stereotypes and ageist perceptions can be addressed through three innovative e-learning activities. The activities employ gamification, videos, and simulations to: (1) provide accurate general information about older people, (2) model management of responsive behaviours in older people with cognitive impairment, and (3) dispel negative stereotypes about older people as dependent and incontinent. In Phase 2, the test case findings will be shared with the advisory group to develop a range of knowledge mobilization strategies to dispel ageism among healthcare professionals and the public. We will implement key short term strategies. DISCUSSION: Findings will generate knowledge on the effectiveness of the e-learning activities in improving student nurses' perceptions about older people. The e-learning learning activities will help student nurses acquire much-needed gerontological knowledge and skills. The strength of this project is in its plan to engage a wide array of stakeholders who will mobilize the phase I findings and advocate for positive perspectives and accurate knowledge about aging-older Canadians, partner organizations (Canadian Gerontological Nurses Association, CanAge, AgeWell), and gerontological experts.

Quilting emergent advanced practice nursing educator identity: an arts-informed approach.

OBJECTIVES: Arts-informed pedagogy in the graduate nursing classroom is used to support the integration of theory with advanced practice nursing (APN) competencies (Canadian Nurses Association, 2008, 2019). METHODS: Using the patterns of knowing (Carper, 1978; Chinn & Kramer, 2018), Iwasiw & Goldenberg's curriculum development model (2015) and practice development (McCormack, Manley, & Titchen, 2013), two course professors facilitated the delivery of an innovative arts-informed approach in a nursing graduate program, the Quilt. RESULTS: The Quilt was meant to invite graduate students to critically reflect and create a visual depiction of their emergent identities as advanced practice nurse educators (APNEs). As three graduate student authors, we reflect on our experiences engaging with arts-informed pedagogy to explore the features of the collective APNE identity. The design and delivery of the Quilt is described. CONCLUSIONS: Finally, we discuss the lessons learned, and the value of arts-informed pedagogy to support the meaningful integration of theory amongst graduate nursing students becoming APNEs.

A Recombinant Protein SARS-CoV-2 Candidate Vaccine Elicits High-titer Neutralizing Antibodies in Macaques.

Background: Vaccines that generate robust and long-lived protective immunity against SARS-CoV-2 infection are urgently required. Methods: We assessed the potential of vaccine candidates based on the SARS-CoV-2 spike in cynomolgus macaques (M. fascicularis) by examining their ability to generate spike binding antibodies with neutralizing activity. Antigens were derived from two distinct regions of the spike S1 subunit, either the N-terminal domain or an extended C-terminal domain containing the receptor-binding domain and were fused to the human IgG1 Fc domain. Three groups of 2 animals each were immunized with either antigen, alone or in combination. The development of antibody responses was evaluated through 20 weeks post-immunization. Results: A robust IgG response to the spike protein was detected as early as 2 weeks after immunization with either protein and maintained for over 20 weeks. Sera from animals immunized with antigens derived from the RBD were able to prevent binding of soluble spike proteins to the ACE2 receptor, shown by in vitro binding assays, while sera from animals immunized with the N-terminal domain alone lacked this activity. Crucially, sera from animals immunized with the extended receptor binding domain but not the N-terminal domain had potent neutralizing activity against SARS-CoV-2 pseudotyped virus, with titers in excess of 10,000, greatly exceeding that typically found in convalescent humans. Neutralizing activity persisted for more than 20 weeks. Conclusions: These data support the utility of spike subunit-based antigens as a vaccine for use in humans.

Exploring Undergraduate Nursing Students' Experiences of Engaging With a Dialectical Behavior Therapy-Skills Group Intervention: Findings of a Thematic Analysis.

STUDY BACKGROUND: Nursing students often have high levels of stress leading to negative consequences for academic performance and overall well-being. Novel strategies are needed to help students manage stress. PURPOSE: To explore students' experiences with an evidence-based intervention-Dialectical Behavior Therapy-Skills Group (DBT-SG). METHODS: We conducted a mixed-methods study to pilot test a DBT-SG intervention, modified for use with undergraduate nursing students. Qualitative data collected as part of this study included focus groups and written responses on a study questionnaire. Thematic analysis of these data was undertaken to explore how students experienced the intervention. The results of this analysis are reported here. RESULTS: Five themes were uncovered: experiencing stress and de-stressing, feeling accepted and validated, acquiring skills, shifting perspectives, and enhanced well-being. CONCLUSIONS: Our findings suggest that by engaging with DBT-SG, nursing students felt accepted and validated, acquired a variety of skills to cope with stress, as well as developed new perspectives, such as the value of practicing self-care, which contributed to enhanced well-being. Future research could build on these results by further exploring how to best create accepting and validating learning environments where students are encouraged to develop interpersonal relationship skills and enact self-care to further support their well-being and professional development.

Behaviour assessment tools in long-term care homes in Canada: a survey.

OBJECTIVE: Many people living in long-term care homes (LTCH) experience changes in behaviour termed the behavioural and psychological symptoms of dementia (BPSD). The valid and reliable assessment of BPSD is essential to guide treatment and monitor the effect of interventions. The aim of this study was to identify behavioural assessment tools implemented in LTCH and factors that impact on their use in clinical care. METHODS: We completed an online mixed-design survey of 300 randomly selected Canadian LTCH between September and November 2018. Respondents were asked to report tools used, reasons for use, methods of administration, training/supports available, confidence in use and challenges faced. Survey results were summarized descriptively and the correlation between implementation supports and confidence examined. Free-text responses were analysed qualitatively. RESULTS: Of 300 LTCH invited to participate, 103 completed the survey. Homes reported using a mean 2.2 ± 1.1 (range 0-7) different tools. The two most commonly used tools were the Dementia Observation System (DOS) and Cohen-Mansfield Agitation Inventory (CMAI). Overall confidence in most aspects of tool use was reported to be high, with workload identified as the greatest challenge. Training and supports correlated with confidence in tool use. Qualitative findings indicate tools provide valuable data to understand behaviours, facilitate team communication, target interventions and track outcomes. CONCLUSIONS: Behavioural assessment tools, in particular a direct observation tool, are widely used in clinical care in Canadian LTCH. Education, enhanced resources, leadership support and applications of technology represent opportunities to improve their use.

Low investment non-pharmacological approaches implemented for older people experiencing responsive behaviours of dementia.

INTRODUCTION: The acute care setting is not ideal for older people with dementia; responsive behaviours may be triggered when care is delivered within a strange environment by staff with limited knowledge of life history and personal preferences. Responsive behaviours (e.g., yelling, hitting, restlessness) are used by older people with dementia to communicate their needs and concerns. It is unknown whether non-pharmacological approaches used by nurses support the development of a meaningful interpersonal relationship between nurses and older people with dementia. AIMS: The aims of this study were to explore: (a) the types of low investment non-pharmacological approaches (e.g., music, social activities) used by nurses caring for older people experiencing responsive behaviours of dementia in acute medical settings and (b) the factors that influence the decisions of these nurses to implement these approaches. METHODS: We present a qualitative secondary analysis of data from a primary study using Thorne's interpretive description approach. Interviews were conducted with 11 nurses and four allied health professionals from acute medical settings in Canada. A qualitative secondary data analytic approach was used, specifically analytic expansion, and experiential thematic analysis. FINDINGS: egardless of the educational preparation of nurses, the decision to use specific types of low investment non-pharmacological approaches were influenced by the perfunctory development of the interpersonal relationships in acute care hospitals. The factors that led nurses to use limited approaches (e.g., turning on the TV and providing a newspaper) were lack of dementia care education and attending to other acutely ill clients. CONCLUSIONS: This study revealed that nurses in acute medical settings require greater practice growth to deliver relational care which is crucial to supporting older people with dementia. Nurses need education and knowledge translation support to use creative low investment non-pharmacological approaches with the intent on upholding the quality of life older people with dementia.

"A recombinant protein SARS-CoV-2 candidate vaccine elicits high-titer neutralizing antibodies in macaques."

Vaccines that generate robust and long-lived protective immunity against SARS-CoV-2 infection are urgently required. We assessed the potential of vaccine candidates based on the SARS-CoV-2 spike in cynomolgus macaques (M. fascicularis) by examining their ability to generate spike binding antibodies with neutralizing activity. Antigens were derived from two distinct regions of the spike S1 subunit, either the N-terminal domain (NTD) or an extended C-terminal domain containing the receptor-binding domain (RBD) and were fused to the human IgG1 Fc domain. Three groups of 2 animals each were immunized with either antigen, alone or in combination. The development of antibody responses was evaluated through 20 weeks post-immunization.

Healthcare professionals' perceptions of P.I.E.C.E.S. education in supporting care delivery for older adults with responsive behaviours of dementia in acute care.

Introduction: In acute care settings persons with dementia often use responsive behaviours such as yelling and hitting as a meaningful mode of communication. Staff dementia care education programs such as P.I.E.C.E.S. may help to address these gaps in care. P.I.E.C.E.S. is a holistic clinical assessment framework that focuses on Physical, Intellectual, and Emotional health, Capabilities of an individual, and the living Environment of a person and the Social being.Aims: The aim of this interpretive descriptive study was to explore the perceptions of healthcare professionals of P.I.E.C.E.S. and recommendations to enhance its uptake.Methods: A total of 15 healthcare professionals from acute medical settings in a hospital in Ontario participated in face-to-face, semi-structured interviews. Experiential thematic and secondary data analyses were performed.Findings: P.I.E.C.E.S. had many positive perceived impacts such as promoting interdisciplinary collaboration. However, participants reported that it was challenging to sustain P.I.E.C.E.S. in practice which led to a tapering off of it approximately one year post-education. A barrier to applying P.I.E.C.E.S. was limited time.Conclusions: Findings indicate the need for educational reinforcements and sustainability strategies for dementia care programs in acute care settings. Organizations should implement regular interdisciplinary meetings to provide opportunities for staff to apply P.I.E.C.E.S.

Decreasing stress and supporting emotional well-being among senior nursing students: A pilot test of an evidence-based intervention.

BACKGROUND: Nursing students can experience stress related to their academic and practice experiences, which can have deleterious effects on physical and emotional well-being. OBJECTIVES: To pilot test an evidence-based intervention, Dialectical Behavior Therapy-Skills Group, designed to promote emotional well-being among nursing students. DESIGN: A single group, pre-posttest design, mixed-method approach. SETTING: A large university situated in a multicultural urban setting. PARTICIPANTS: Senior undergraduate nursing students (n = 31). METHODS: Students participated in an 8-week modified Dialectical Behavior Therapy-Skills Group (DBT-SG) intervention. Quantitative and qualitative data were collected to explore the interventions' feasibility, acceptability, and students' perceptions of its applicability to practice. Students also completed standardized outcome measures of psychological distress and emotional well-being pre- and post-intervention to evaluate preliminary effectiveness. RESULTS: Overall feedback was positive, with participants describing how skill modules helped them establish relationships and manage stress in clinical, academic, and personal settings. Significant reductions in stress and improvements in well-being were also reported. CONCLUSION: Results suggest that DBT-SG offers a promising approach for mitigating nursing students' stress by helping them acquire practice-relevant strengths and self-care strategies. Further research is required to examine the effectiveness of DBT-SG among other nursing student groups, as well as to explore optimal approaches to delivering this intervention in conjunction with nursing curricula.

Agitation Detection in People Living with Dementia using Multimodal Sensors.

People Living with Dementia (PLwD) often exhibit behavioral and psychological symptoms of dementia; with agitation being one of the most prevalent symptoms. Agitated behaviour in PLwD indicates distress and confusion and increases the risk to injury to both the patients and the caregivers. In this paper, we present the use of wearable devices to detect agitation in PLwD. We hypothesize that combining multi-modal sensor data can help in building better classifiers to identify agitation in PLwD in comparison to a single sensor. We present a unique study to collect motion and physiological data from PLwD. This multi-modal sensor data is subsequently used to build predictive models to detect agitation in PLwD. The results on Random Forest for 28 days of data from PLwD show a strong evidence to support our hypothesis and highlight the importance of using multi-modal sensor data for detecting agitation events amongst them.
