Privileging place: reflections on involving people with dementia in recidency

Although attention is paid to involving people with dementia as collaborators in research, the issue of place – where involvement actually occurs – has been neglected. This is significant because we know from the academic literature that places can adversely affect social relations and a person’s ability to participate as equal partners. This paper privileges place and documents our experiences of running residencies in the English Lake District with people with dementia – Houston, Gardiner and Wallace all have some form of dementia. In doing so we provide a model to reference for involving people with dementia in research and knowledge production, while simultaneously strengthening the evidence base for the residency as a method for participatory research. People with dementia participated in two residencies to co-produce a touring exhibition and educational resource as part of a research dissemination project. We found that by privileging place a more equitable, productive, healthier, and respectful way of involving people with dementia as collaborators in research dissemination could be realised. The project has wider implications for the involvement of people with dementia in not only research, but also public consultations, service evaluations, and policy-related work

Increasing Passersby Engagement with Public Large Interactive Displays: A Study of Proxemics and Conation

The definitive version was published in the Proceedings of the 2018 International Conference on Human Factors on Computing Systems on the ACM Digital Library at https://dx.doi.org/10.1145/3279778.3279789Prior research has shown that large interactive displays de- ployed in public spaces are often underutilized, or even un- noticed, phenomena connected to ‘interaction’ and ‘display blindness’, respectively. To better understand how designers can mitigate these issues, we conducted a field experiment that compared how different visual cues impacted engagement with a public display. The deployed interfaces were designed to progressively reveal more information about the display and entice interaction through the use of visual content designed to evoke direct or indirect conation (the mental faculty related to purpose or will to perform an action), and different ani- mation triggers (random or proxemic). Our results show that random triggers were more effective than proxemic triggers at overcoming display and interaction blindness. Our study of conation – the first we are aware of – found that “conceptual” visuals designed to evoke indirect conation were also useful in attracting people’s attention.Natural Sciences and Engineering Research Council of Canad

Impact of Interprofessional Student Teams at a Remote Area Medical Event in Rural Appalachia

Introduction: Education in interprofessional collaboration is vital to expand healthcare access, especially in areas of higher disparity. To address this need, interprofessional faculty collaborators incorporated undergraduate and graduate health profession students into teams at an annual Remote Area Medical event in rural Appalachia between 2017 and 2020. Purpose: This article evaluates the impact of an interprofessional student teams model on both patient care experience and students’ interprofessional collaboration attitudes and behaviors. Methods: Student volunteers completed pre- and post-event surveys containing questions about demographics, open-ended questions, and questions from two instruments: the Student Perceptions of Interprofessional Clinical Education-Revised Instrument, Version 2 (SPICE-R2) and the Interprofessional Collaborative Competency Attainment Scale-Revised (ICCAS-R). Quantitative data were analyzed statistically; qualitative data thematically. Tally forms collected patient care interventions that were compared to regional health disparities. Two years of survey data and four years of intervention data were analyzed. Results: There was an increase (p \u3c 0.001) in the post-event survey SPICE-R2 factors (teamwork, healthcare outcomes, and roles and responsibilities) in 2020 but not in 2019. ICCAS-R mean post-event composite scores increased (p \u3c 0.05) in both 2019 and 2020. Qualitative coding of open-ended responses revealed interprofessional competency themes and provided event feedback. Over 5,900 health-disparity-focused interventions were completed between 2017 and 2020. Implications: Students participating in interprofessional teams demonstrate changes in attitudes towards the interprofessional approach to care, an improved ability to collaborate interprofessionally, and a positive impact on patient care interventions. The findings allow educators to understand how experiential interprofessional education influences students’ interprofessional attitudes and beliefs while benefitting patient care

A Match Made in Heaven: Exploring Views of Medicine Students, Pharmacy Interns and Facilitators in an Interprofessional Medicines Pilot Study

Purpose: To date, few interprofessional education initiatives have included just medicine and pharmacy learners. This research sought to explore learners’ and facilitators’ views of an interprofessional education medicines pilot study involving medical students and pharmacy interns. Methods: Qualitative feedback was gathered from the participating learners and a facilitator focus group was undertaken. Results: Medical student and pharmacy intern learners reported enjoying taking part and found the simulation and overall initiative to be authentic. They described learning most about each other’s roles and responsibilities and about teamwork, collaborative management, and collaboration. Some logistical improvements were suggested. The facilitators judged that the topic of medicines, with medical and pharmacy learners taking part, to be a match made in heaven. Conclusions: Medical student and pharmacy intern learners found the medicines topic and discipline grouping facilitated their learning. Some topics and groups of disciplines are ideally matched for IPE and such a nexus should be capitalised upon

Targeting liver myofibroblasts: a novel approach in anti-fibrogenic therapy

Chronic liver disease results in a liver-scarring response termed fibrosis. Excessive scarring leads to cirrhosis, which is associated with high morbidity and mortality. The only treatment for liver cirrhosis is liver transplantation; therefore, much attention has been directed toward therapies that will slow or reverse fibrosis. Although anti-fibrogenic therapies have been shown to be effective in experimental animal models, licensed therapies have yet to emerge. A potential problem for any anti-fibrogenic therapy in the liver is the existence of the body’s major drug metabolising cell (the hepatocyte) adjacent to the primary fibrosis-causing cell, the myofibroblast. This article reviews the development of a human recombinant single-chain antibody (scAb) that binds to the surface of myofibroblasts. This antibody binds specifically to myofibroblasts in fibrotic mouse livers. When conjugated with a compound that stimulates myofibroblast apoptosis, the antibody directs the specific apoptosis of myofibroblasts with greater specificity and efficacy than the free compound. The antibody also reduces the adverse effect of liver macrophage apoptosis and—in contrast to the free compound—reversed fibrosis in the sustained injury model used. These data suggest that specifically stimulating the apoptosis of liver myofibroblasts using a targeting antibody has potential in the treatment of liver fibrosis

SKS Splitting Beneath Mount St. Helens: Constraints on Subslab Mantle Entrainment

Observations of seismic anisotropy can provide direct constraints on the character of mantleflow in subduction zones, critical for our broader understanding of subduction dynamics. Here wepresent over 750 new SKS splitting measurements in the vicinity of Mount St. Helens in the Cascadiasubduction zone using a combination of stations from the iMUSH broadband array and Cascades VolcanoObservatory network. This provides the highest density of splitting measurements yet available inCascadia, acting as a focused“telescope”for seismic anisotropy in the subduction zone. We retrieve spatiallyconsistent splitting parameters (mean fast directionΦ: 74°, mean delay time∂t: 1.0 s) with the azimuthaloccurrence of nulls in agreement with the fast direction of splitting. When averaged across the array, a90° periodicity in splitting parameters as a function of back azimuth is revealed, which has not beenrecovered previously with single‐station observations. The periodicity is characterized by a sawtooth patterninΦwith a clearly defined 45° trend. We present new equations that reproduce this behavior based uponknown systematic errors when calculating shear wave splitting from data with realistic seismic noise.The corrected results suggest a single layer of anisotropy with an ENE‐WSW fast axis parallel to the motionof the subducting Juan de Fuca plate; in agreement with predictions for entrained subslab mantleflow. Thesplitting pattern is consistent with that seen throughout Cascadia, suggesting that entrainment of theunderlying asthenosphere with the subducting slab is coherent and widespread.The broadband seismic component of the iMUSH project was supported by National Science Foundation grants EAR‐1144568, EAR‐1144351, EAR‐1460291, and EAR‐1444275.
