Methodological Reflections of a Student- and Community-based Partnership on Operationalizing a Community-based Participatory Research Model: Recommendations for Building, Securing, and Sustaining Partnerships.

BACKGROUND: Community-based participatory research (CBPR) is an approach that values community expertise and ownership in creating knowledge. This approach's success is challenged by inherent cultural imbalances, making it difficult to sustain partnerships and build from what has been learned from a project as it develops. As student researchers and community members, we reflected on the challenges in CBPR and gave guidance to future novice researchers pursuing CBPR. OBJECTIVES: From the application of an initial CBPR model as a framework to our partnership, we propose empirical avenues to continuously adapt the CBPR approach. METHODS: A CBPR partnership between McGill's Family Medicine Graduate Student Society and Share the Warmth, a community-based organization aiming to fight poverty and hunger, was formed to collaboratively assess a music program offered in a socioeconomically disadvantaged community. The partnership process was based on a model that we conceptualized in three phases of our framework: building, securing, and sustaining. We reflect on the facilitators and challenges of this project and propose solutions to overcome identified barriers within the context of our partnership. RESULTS: We highlight the importance of integrating student partners in the community, reevaluating formal research agreements, and coordinating the transition of new partners in this adaptive CBPR model. We argue that this systematic and reflexive process has made the model especially useful as a framework for student and community partnerships. CONCLUSIONS: We propose adaptive components to the CBPR model. Our recommendations could help other partnerships cultivate CBPR to be more applicable in community health research.

Description of organizational and clinician characteristics of primary dementia care in Canada: a multi-method study.

BACKGROUND: Organizational and clinician characteristics are important considerations for the implementation of evidence-based recommendations into primary care practice. The introduction of Canadian dementia practice guidelines and Alzheimer strategies offers a unique context to study which of the organizational and clinician characteristics align with good quality care in primary care practices. METHODS: To evaluate the quality of dementia care, we carried out a retrospective chart review in randomly selected patients with a diagnosis of dementia and who had a visit during a 9-month period in 33 primary care practices. We collected data on indicators that were based on existing Canadian evidence-based recommendations to measure a quality of dementia care score. In addition, four questionnaires were administered: two questionnaires to evaluate the organizational characteristics of the practices (dementia-specific and general organization) and two to evaluate the clinician characteristics (one for family physicians and one for nurses). Primary care practices were stratified into tertiles based on their average quality of dementia care score (low, moderate, high). The differences between the groups organizational and clinician questionnaires scores were analyzed descriptively and visually. RESULTS: The mean overall scores for each questionnaire were higher in the high quality of dementia care group. When looking at the breakdown of the overall score into each characteristic, the high-quality group had a higher average score for the dementia-specific organizational characteristics of "access to and coordination with home and community services", "financial support", "training", "coordination and continuity within the practice", and "caregiver support and involvement". The characteristic "Leadership" showed a higher average score for the moderate and high-quality groups than the low-quality group. In both clinician questionnaires, the high group scored better in "attitudes towards the Alzheimer's plan" than the other two groups. CONCLUSIONS: These results suggest that investing in organizational characteristics specifically aimed at dementia care is a promising avenue to improve quality of dementia care in primary care. These results may be useful to enhance the implementation of evidence-based practices and improve the quality of dementia care.

The association between the level of institutional support for dementia care in primary care practices and the quality of dementia primary care: A retrospective chart review.

INTRODUCTION: Institutional support, encompassing financial and training support, as well as interdisciplinary teams, may be important for the quality of dementia primary care for persons living with dementia. The aim of this study was to measure the association between the level of institutional support provided to primary care practices and the quality of dementia care. METHODS: This was a cross-sectional chart review in 33 Canadian primary care practices to measure the quality of dementia primary care using a quality of follow-up score. The score was based on the assessment of 10 indicators. Practices were chosen using a purposeful sampling method with varying levels of institutional support for dementia primary care (e.g., financial support, training, interdisciplinary team). A linear mixed-effect model was used to measure the association between the level of institutional support and the quality of dementia care. RESULTS: There was a significant association between the level of institutional support and the quality of dementia care (mean difference = 23.5, 95% confidence interval: 16.4, 30.6). DISCUSSION: Providing more institutional support for primary care practices could be a promising avenue to improve the care of persons living with dementia.

Hospital-at-Home Interventions vs In-Hospital Stay for Patients With Chronic Disease Who Present to the Emergency Department: A Systematic Review and Meta-analysis.

Importance: Hospitalizations are costly and may lead to adverse events; hospital-at-home interventions could be a substitute for in-hospital stays, particularly for patients with chronic diseases who use health services more than other patients. Despite showing promising results, heterogeneity in past systematic reviews remains high. Objective: To systematically review and assess the association between patient outcomes and hospital-at-home interventions as a substitute for in-hospital stay for community-dwelling patients with a chronic disease who present to the emergency department and are offered at least 1 home visit from a nurse and/or physician. Data Sources: Databases were searched from date of inception to March 4, 2019. The databases were Ovid MEDLINE, Ovid Embase, Ovid PsycINFO, CINAHL, Health Technology Assessment, the Cochrane Library, OVID Allied and Complementary Medicine Database, the World Health Organization International Clinical Trials Registry Platform, and ClinicalTrials.gov. Study Selection: Randomized clinical trials in which the experimental group received hospital-at-home interventions and the control group received the usual in-hospital care. Patients were 18 years or older with a chronic disease who presented to the emergency department and received home visits from a nurse or physician. Data Extraction and Synthesis: Risk of bias was assessed, and a meta-analysis was conducted for outcomes that were reported by at least 2 studies using comparable measures. Risk ratios (RRs) were reported for binary outcomes and mean differences for continuous outcomes. Narrative synthesis was performed for other outcomes. Main Outcomes and Measures: Outcomes of interest were patient outcomes, which included mortality, long-term care admission, readmission, length of treatment, out-of-pocket costs, depression and anxiety, quality of life, patient satisfaction, caregiver stress, cognitive status, nutrition, morbidity due to hospitalization, functional status, and neurological deficits. Results: Nine studies were included, providing data on 959 participants (median age, 71.0 years [interquartile range, 70.0-79.9 years]; 613 men [63.9%]; 346 women [36.1%]). Mortality did not differ between the hospital-at-home and the in-hospital care groups (RR, 0.84; 95% CI, 0.61-1.15; I2 = 0%). Risk of readmission was lower (RR, 0.74; 95% CI, 0.57-0.95; I2 = 31%) and length of treatment was longer in the hospital-at-home group than in the in-hospital group (mean difference, 5.45 days; 95% CI, 1.91-8.97 days; I2 = 87%). In addition, the hospital-at-home group had a lower risk of long-term care admission than the in-hospital care group (RR, 0.16; 95% CI, 0.03-0.74; I2 = 0%). Patients who received hospital-at-home interventions had lower depression and anxiety than those who remained in-hospital, but there was no difference in functional status. Other patient outcomes showed mixed results. Conclusions and Relevance: The results of this systematic review and meta-analysis suggest that hospital-at-home interventions represent a viable substitute to an in-hospital stay for patients with chronic diseases who present to the emergency department and who have at least 1 visit from a nurse or physician. Although the heterogeneity of the findings remained high for some outcomes, particularly for length of treatment, the heterogeneity of this study was comparable to that of past reviews and further explored.

Identifying and Classifying Tools for Health Policy Ethics Review: A Systematic Search and Review.

Ethical review and analysis of health policy may help to ensure policies address the needs of society and align with relevant values and principles. Indeed, researchers and bioethicists have recognized the need for ethical frameworks specifically for public health applications. The objective of this research was to compile structured tools for ethical review of (drafted or existing) health policy and to analyze these tools for their scope and philosophical underpinnings. A systematic search and review of academic and grey literature was conducted to compile existing tools designed for health policy ethics review. The search yielded 13 health policy ethical review tools. Qualitative content analysis revealed that all of the tools were influenced by multiple ethical values and that a majority were influenced by more than one ethical theory. The most common values were non-maleficence and beneficence (92.3%). The most common influencing ethical theory was the Principles Approach (92.3%). The structure of the tools demonstrates a heterogeneity of methodology designs to approach policy ethics review. This research offers a unique contribution to the bioethics field that provides a useful resource and understanding of the current ethical review tools for health policy.

Sex differences in the management of persons with dementia following a subnational primary care policy intervention.

BACKGROUND: The influence of sex and gender on the risk of dementia, its clinical presentation and progression is increasingly being recognized. However, current dementia strategies have not explicitly considered sex and gender differences in the management of dementia to ensure equitable care. The objective of this study was to examine the moderating effect of sex on the quality of care following the implementation of the Quebec Alzheimer Plan (QAP). METHODS: We conducted a secondary analysis of the evaluation of the QAP consisting of a retrospective chart review of 945 independent, randomly-selected patient charts of males and females 75+ years old with dementia and a visit to one of 13 participating Family Medicine Groups before (October 2011-July 2013) and after (October 2014 - July 2015). The quality of dementia care score, based on Canadian and international recommendations and consensus guidelines, consisted of documented assessments in 10 domains. We used a mixed linear regression model to measure the interaction between sex and the implementation of the QAP on the quality of dementia care score, adjusting for age and number of medications. RESULTS: We found that improvements in the quality of dementia care following the QAP were larger for men than women (mean difference = 4.97; 95%CI: 0.08, 9.85). We found that men had a larger improvement in four indicators (driving assessments, dementia medication management, Alzheimer Society referrals, and functional status evaluation), while women had a smaller improvement in three (home care needs, behavioural and psychological symptoms of dementia, and weight). Men were prescribed fewer anticholinergics post-QAP, while women were prescribed more. Cognitive testing improved in men but decreased for women following the QAP; the opposite was observed for caregiver needs. CONCLUSION: While the overall quality of care improved after the implementation of the QAP, this study reveals differences in dementia management between men and women. While we identified areas of inequalities in the care received, it is unclear whether this represents inequities in access to care and health outcomes. Future research should focus on better understanding sex and gender-specific needs in dementia to bridge this gap and better inform dementia strategies.

Towards a Patient-Centred Regulation of Gamete Donation in Canada.

Commercial gamete donation in Canada is prohibited by the Assisted Human Reproduction Act. However, the Act permits gamete recipients to reimburse donors for donation-related expenses. Until recently, the types of expenses that were eligible and the process for reimbursing donors were not specified. In 2016, Health Canada announced its intent to develop regulations that would regulate gamete donor reimbursement; it released the proposed policy in 2017. As a result of consultations with Canadian lawmakers, physicians, and patients, debates surrounding commercial gamete donation are being revisited. Considering the ethical implications of gamete donation payment arrangements, a patient-centred care framework is useful going forward in the regulation of this practice. Patient-centred values of communication, respecting relational autonomy, and respecting patient interests should guide decisions regarding regulation of gamete donation arrangements in Canada.

Cardiac actin changes in the actomyosin interface have different effects on myosin duty ratio.

Hypertrophic cardiomyopathy (HCM) is an inherited cardiovascular disease (CD) that commonly causes an increased size of cardiomyocytes in the left ventricle. The proteins myosin and actin interact in the myocardium to produce contraction through the actomyosin ATPase cycle. The duty ratio (r) of myosin is the proportion of the actomyosin ATPase cycle that myosin is bound to actin and does work. A common hypothesis is that HCM mutations increase contraction in cardiac sarcomeres; however, the available data are not clear on this connection. Based on previous work with human α-cardiac actin (ACTC), we hypothesize that HCM-linked ACTC variants with alterations near the myosin binding site have an increased r, producing more force. Myosin duty ratios using human ACTC variant proteins were calculated with myosin ATPase activity and in-vitro motility data. We found no consistent changes in the duty ratio of the ACTC variants, suggesting that other factors are involved in the development of HCM when ACTC variants are present.

Potential role of ferric hemoglobin in MS pathogenesis: Effects of oxidative stress and extracellular methemoglobin or its degradation products on myelin components.

There is a well-documented relationship between cerebral vasculature and multiple sclerosis (MS) lesions: abnormal accumulations of iron have been found in the walls of the dilated veins in cerebral MS plaques. The source of this iron is unknown, but could be related to the recognized phenomenon of capillary and venous hemorrhages leading to blood extravasation. In turn, hemorrhaging leading to hemolysis results in extracellular release of hemoglobin, a reactive molecule that could induce local oxidative stress, inflammation, and tissue damage. Our previous studies with a reduced form of hemoglobin (oxyHb) have demonstrated its ability to cause extensive lipid and protein oxidation in vitro, which would result in membrane destabilization. Here, we investigated in further detail the mechanism by which the more abundant oxidized form of extracellular hemoglobin (metHb), and dissociated hemin, cause direct oxidative damage to myelin components, specifically membrane-mimetic lipid vesicles and myelin basic protein (MBP), a highly-abundant protein in the CNS. Oxidation of lipids was assessed by the formation of conjugated diene/triene and malondialdehyde, and oxidation of MBP was demonstrated by the bityrosine formation and by the change in protein mass. Our results show that metHb causes oxidative damage to MBP and myelin lipids, partly by transferring its hemin moiety to protein and lipid, but mostly as an intact protein possibly via formation of a ferryl radical. These results elucidating the mechanism of extracellular hemoglobin-induced oxidative damage to myelin components support the need for further research into vascular pathology in MS pathogenesis, to gain insight into the role of iron deposits and/or in stimulation of different comorbidities associated with the disease.
