Thinking and Enacting the Patient Medical Home Under Pandemic Conditions: A Qualitative Study From Primary Care in Alberta, Canada.

BACKGROUND: The COVID-19 (C19) pandemic shocked primary care systems around the world. Those systems responded by supporting patients in the community, and acute care facilities in crisis. In Canada, the Patient Medical Home (PMH) is a widely adopted care model that aims to operationalize the tenets and principles of Primary Health Care (PHC) as developed since the Alma-Ata Declaration. This paper describes how personnel working in and with Primary Care Networks (PCNs) in Alberta, Canada deployed the PMH model and its underlying PHC principles to frame and respond to the C19 shock. METHODS: Using purposive and snowball sampling techniques, we interviewed 57 participants who worked in public health and primary care, including community-based family physicians. We used interpretive description to analyze the interviews. RESULTS: PCN staff and physicians described how the PMH model was foundational to normal operations, and how C19 responses were framed by the patient-centric, team-delivered, and continuous care principles the model shares with PHC. Specifically, participants described ensuring access to care, addressing the social determinants of health, being patient centered, and redeploying and expanding PHC teams to accomplish these goals. DISCUSSION: Delivering PHC through the PMH allowed physicians and allied health staff to deliver patient-centered, team-based, holistic bio-medical services to Albertans. In tailoring services to meet the specific social and health needs of the populations served by each PCN, healthcare providers were able to ensure relevant support remained available and accessible.

Laboratory and In situ Selenium Bioaccumulation Assessment in the Benthic Macroinvertebrates Hyalella azteca and Chironomus dilutus.

Selenium (Se) bioaccumulation and toxicity in aquatic vertebrates have been thoroughly investigated. Limited information is available on Se bioaccumulation at the base of aquatic food webs. In this study, we evaluated Se bioaccumulation in two benthic macroinvertebrates (BMI), Hyalella azteca and Chironomus dilutus raised in the laboratory and caged in-situ to a Canadian boreal lake e (i.e., McClean Lake) that receives continuous low-level inputs of Se (< 1 µg/L) from a uranium mill. Additional Se bioaccumulation assays were conducted in the laboratory with these BMI to (i) confirm field results, (ii) compare Se bioaccumulation in lab-read and native H. azteca populations and (iii) identify the major Se exposure pathway (surface water, top 1 cm and top 2-3 cm sediment layers) leading to Se bioaccumulation in H. azteca. Field and laboratory studies indicated overall comparable Se bioaccumulation and trophic transfer factors (TTFs) in co-exposed H. azteca (whole-body Se 0.9-3.1 µg/g d.w; TTFs 0.6-6.3) and C. dilutus (whole-body Se at 0.7-3.2 µg Se/g d.w.; TTFs 0.7-3.4). Native and lab-reared H. azteca populations exposed to sediment and periphyton from McClean Lake exhibited similar Se uptake and bioaccumulation (NLR, p = 0.003; 4.1 ± 0.8 µg Se/g d.w), demonstrating that lab-reared organisms are good surrogates to assess on-site Se bioaccumulation potential. The greater Se concentrations in H. azteca exposed to the top 1-3 cm sediment layer relative to waterborne exposure, corroborates the importance of the sediment-detrital pathway leading to greater Se bioaccumulation potential to higher trophic levels via BMI.

Understanding Suicide from an Indigenous Cultural Lens: Insights from Elders in Canada.

In this study, Indigenous Elders in Canada were interviewed to explore their conceptualizations of death and dying, particularly in relation to suicide. Through reflexive thematic analysis, three key themes were developed: Indigenous conceptions of death and dying, Christian influences on views of suicide, and indirect suicide. The theme of Indigenous conceptualizations of death and dying included the subthemes of spirituality and life after death, highlighting the importance of spiritual beliefs in Indigenous culture and knowledge systems. The impact of Christian influences on views of suicide was also explored, with participants discussing the complex nature of the relationship between Christianity and Indigenous peoples. Finally, the theme of indirect suicide was analyzed, referring to deaths resulting from behaviors that do not necessarily fit within the conventional definition of suicide. Overall, this study highlights the importance of honoring Indigenous cultural knowledge in research related to suicide prevention in Indigenous communities.

Incorporating First Nations, Inuit and Métis Traditional Healing Spaces within a Hospital Context: A Place-Based Study of Three Unique Spaces within Canada's Oldest and Largest Mental Health Hospital.

Globally and historically, Indigenous healthcare is efficacious, being rooted in Traditional Healing (TH) practices derived from cosmology and place-based knowledge and practiced on the land. Across Turtle Island, processes of environmental dispossession and colonial oppression have replaced TH practices with a colonial, hospital-based system found to cause added harm to Indigenous Peoples. Growing Indigenous health inequities are compounded by a mental health crisis, which begs reform of healthcare institutions. The implementation of Indigenous knowledge systems in hospital environments has been validated as a critical source of healing for Indigenous patients and communities, prompting many hospitals in Canada to create Traditional Healing Spaces (THSs). After ten years, however, there has been no evaluation of the effectiveness of THSs in Canadian hospitals in supporting healing among Indigenous Peoples. In this paper, our team describes THSs within the Center for Addiction and Mental Health (CAMH), Canada's oldest and largest mental health hospital. Analyses of 22 interviews with hospital staff and physicians describe CAMH's THSs, including what they look like, how they are used, and by whom. The results emphasize the importance of designating spaces with and for Indigenous patients, and they highlight the wholistic benefits of land-based treatment for both clients and staff alike. Transforming hospital spaces by implementing and valuing Indigenous knowledge sparks curiosity, increases education, affirms the efficacy of traditional healing treatments as a standard of care, and enhances the capacity of leaders to support reconciliation efforts.

Identification of nectar sources foraged by female mosquitoes in Canada.

For many mosquito species, the females must obtain vertebrate blood to complete a gonotrophic cycle. These blood meals are frequently supplemented by feeding on sugary plant nectar, which sustains energy reserves needed for flight, mating, and overall fitness. Our understanding of mosquito nectar foraging behaviors is mostly limited to laboratory experiments and direct field observations, with little research into natural mosquito-host plant relationships done in North America. In this study, we collected nectar-fed female mosquitoes over a 2-year period in Manitoba, Canada, and amplified a fragment of the chloroplast rbcL gene to identify the plant species fed upon. We found that mosquitoes foraged from diverse plant families (e.g., grasses, trees, ornamentals, and legumes), but preferred certain species, most notably soybean and Kentucky blue grass. Moreover, there appeared to be some associations between plant feeding preferences and mosquito species, date of collection, landscape, and geographical region. Overall, this study implemented DNA barcoding to identify nectar sources forage by mosquitoes in the Canadian Prairies.

Exploring the Use of Persuasive System Design Principles to Enhance Medication Incident Reporting and Learning Systems: Scoping Reviews and Persuasive Design Assessment.

BACKGROUND: Medication incidents (MIs) causing harm to patients have far-reaching consequences for patients, pharmacists, public health, business practice, and governance policy. Medication Incident Reporting and Learning Systems (MIRLS) have been implemented to mitigate such incidents and promote continuous quality improvement in community pharmacies in Canada. They aim to collect and analyze MIs for the implementation of incident preventive strategies to increase safety in community pharmacy practice. However, this goal remains inhibited owing to the persistent barriers that pharmacies face when using these systems. OBJECTIVE: This study aims to investigate the harms caused by medication incidents and technological barriers to reporting and identify opportunities to incorporate persuasive design strategies in MIRLS to motivate reporting. METHODS: We conducted 2 scoping reviews to provide insights on the relationship between medication errors and patient harm and the information system-based barriers militating against reporting. Seven databases were searched in each scoping review, including PubMed, Public Health Database, ProQuest, Scopus, ACM Library, Global Health, and Google Scholar. Next, we analyzed one of the most widely used MIRLS in Canada using the Persuasive System Design (PSD) taxonomy-a framework for analyzing, designing, and evaluating persuasive systems. This framework applies behavioral theories from social psychology in the design of technology-based systems to motivate behavior change. Independent assessors familiar with MIRLS reported the degree of persuasion built into the system using the 4 categories of PSD strategies: primary task, dialogue, social, and credibility support. RESULTS: Overall, 17 articles were included in the first scoping review, and 1 article was included in the second scoping review. In the first review, significant or serious harm was the most frequent harm (11/17, 65%), followed by death or fatal harm (7/17, 41%). In the second review, the authors found that iterative design could improve the usability of an MIRLS; however, data security and validation of reports remained an issue to be addressed. Regarding the MIRLS that we assessed, participants considered most of the primary task, dialogue, and credibility support strategies in the PSD taxonomy as important and useful; however, they were not comfortable with some of the social strategies such as cooperation. We found that the assessed system supported a number of persuasive strategies from the PSD taxonomy; however, we identified additional strategies such as tunneling, simulation, suggestion, praise, reward, reminder, authority, and verifiability that could further enhance the perceived persuasiveness and value of the system. CONCLUSIONS: MIRLS, equipped with persuasive features, can become powerful motivational tools to promote safer medication practices in community pharmacies. They have the potential to highlight the value of MI reporting and increase the readiness of pharmacists to report incidents. The proposed persuasive design guidelines can help system developers and community pharmacy managers realize more effective MIRLS.

Screening for lung cancer with computed tomography: protocol for systematic reviews for the Canadian Task Force on Preventive Health Care.

PURPOSE: Lung cancer is the leading cause of cancer deaths in Canada, and because early cancers are often asymptomatic screening aims to prevent mortality by detecting cancer earlier when treatment is more likely to be curative. These reviews will inform updated recommendations by the Canadian Task Force on Preventive Health Care on screening for lung cancer. METHODS: We will update the review on the benefits and harms of screening with CT conducted for the task force in 2015 and perform de novo reviews on the comparative effects between (i) trial-based selection criteria and use of risk prediction models and (ii) trial-based nodule classification and different nodule classification systems and on patients' values and preferences. We will search Medline, Embase, and Cochrane Central (for questions on benefits and harms from 2015; comparative effects from 2012) and Medline, Scopus, and EconLit (for values and preferences from 2012) via peer-reviewed search strategies, clinical trial registries, and the reference lists of included studies and reviews. Two reviewers will screen all citations (including those in the previous review) and base inclusion decisions on consensus or arbitration by another reviewer. For benefits (i.e., all-cause and cancer-specific mortality and health-related quality of life) and harms (i.e., overdiagnosis, false positives, incidental findings, psychosocial harms from screening, and major complications and mortality from invasive procedures as a result of screening), we will include studies of adults in whom lung cancer is not suspected. We will include randomized controlled trials comparing CT screening with no screening or alternative screening modalities (e.g., chest radiography) or strategies (e.g., CT using different screening intervals, classification systems, and/or patient selection via risk models or biomarkers); non-randomized studies, including modeling studies, will be included for the comparative effects between trial-based and other selection criteria or nodule classification methods. For harms (except overdiagnosis) we will also include non-randomized and uncontrolled studies. For values and preferences, the study design may be any quantitative design that either directly or indirectly measures outcome preferences on outcomes pertaining to lung cancer screening. We will only include studies conducted in Very High Human Development Countries and having full texts in English or French. Data will be extracted by one reviewer with verification by another, with the exception of result data on mortality and cancer incidence (for calculating overdiagnosis) where duplicate extraction will occur. If two or more studies report on the same comparison and it is deemed suitable, we will pool continuous data using a mean difference or standardized mean difference, as applicable, and binary data using relative risks and a DerSimonian and Laird model unless events are rare (< 1%) where we will pool odds ratios using Peto's method or (if zero events) the reciprocal of the opposite treatment arm size correction. For pooling proportions, we will apply suitable transformation (logit or arcsine) depending on the proportions of events. If meta-analysis is not undertaken we will synthesize the data descriptively, considering clinical and methodological differences. For each outcome, two reviewers will independently assess within- and across-study risk of bias and rate the certainty of the evidence using GRADE (Grading of Recommendations Assessment, Development, and Evaluation), and reach consensus. DISCUSSION: Since 2015, additional trials and longer follow-ups or additional data (e.g., harms, specific patient populations) from previously published trials have been published that will improve our understanding of the benefits and harms of screening. The systematic review of values and preferences will allow fulsome insights that will inform the balance of benefits and harms. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42022378858.

Defining "Essential Digital Health for the Underserved".

The World Health Organization envisions achieving "Health for All," to strive for equitable access to important health information and services to attain wellness (WHO 2023a). The COVID-19 pandemic reshaped the Canadian health system toward increasing digital health services, which improved access for some but underserved others. Integrating digital health into holistic health services delivery deserves careful consideration. This paper introduces the concept of "essential digital health for the underserved," by first defining the terms "digital health," "essential" and "underserved." Then, we share a summary of a discussion at a May 2023 conference with stakeholders, including patients, caregivers, health professionals, health policy makers, private sectors and health researchers. A series of papers follow to explore how digital health can help chart a responsible course for the future of essential digital health in Canada. In this post-pandemic era - with a health human resources shortage through attrition and retirement, an increased health service demand from patients and a greater strain on our recovering economy - innovative solutions need to be implemented to strengthen our Canadian health system.

Care and services partnership in Quebec birthing centres: myth or reality?

CONTEXT: Working with women to best meet their needs has always been central to midwifery in Quebec, Canada. The creation of birthing centres at the end of the 1990s consolidated this desire to prioritize women's involvement in perinatal care and was intended to encourage the establishment of a care and services partnership between care providers and users. The aim of this pilot study is to evaluate the perceptions of clients, midwives and birth assistants of the way in which women are involved in partnership working in Quebec birthing centres. METHODS: A single qualitative case and pilot study was conducted with midwives (n = 5), birth assistants (n = 4), a manager (n = 1), clients (n = 5) and members of the users' committee (n = 2) at a birthing centre in Quebec, Canada in July and August 2023. The partnership was evaluated using the dimensions of a validated CADICEE questionnaire. RESULTS: The women and professionals stressed that the relationship was established in a climate of trust. The caregivers also attached importance to autonomy, information sharing and decision-making, adaptation to context, empathy and recognition of the couple's expertise. The women confirmed that they establish a relationship of trust with the professionals when the latter show empathy and that they adapt the follow-up to their knowledge and life context. Key factors in establishing this kind of care relationship are the time given, a de-medicalized environment, the comprehensive care received, and professionals who are well-informed about the partnership. In addition, the birthing centre has a users' committee that can put forward ideas but has no decision-making powers. CONCLUSIONS: Both the women and the professionals at the birthing centre appear to be working in partnership. However, at the organizational level, the women are not involved in decision-making. A study of all birthing centres in Quebec would provide a more comprehensive picture of the situation.

Enhancing nursing education for Indigenous students: Indigenous nursing students' insights and strategies.

BACKGROUND: Indigenous nursing students contended with far-reaching challenges during the pandemic that significantly altered their experiences of nursing education. These experiences are poorly understood by nursing educators and strategies for Indigenous nursing student success rarely involve the insights of current Indigenous nursing students. AIM: The aim of this article is to offer Indigenous-student derived recommendations regarding strategies for improving their experiences and success within nursing education during the pandemic and beyond. DESIGN AND METHODS: This qualitative study employed an Indigenous methodology including land-based learning, ceremony, and sharing circles. PARTICIPANTS AND SETTING: Indigenous nursing students (n = 17) from a Western Canadian school of nursing participated in one of three sharing circles. RESULTS: Indigenous nursing students recommended institutional and program adaptations along with increases to cultural safety for enhancing their experience in nursing education. Institutional and program strategies included: decreasing course loads and class sizes; an Indigenous-specific cohort; a transition program after course failure; increasing academic supports such as additional clinical skills and academic writing practice. Recommendations for increasing cultural safety included: mandatory and recurrent cultural safety training for faculty, staff and students; differential learning and evaluation strategies; and increased inclusion of Indigenous ceremonies and practices. CONCLUSION: The findings of this study provide insights that can help guide curriculum development, pedagogical approaches, and policy development to improve nursing education for Indigenous students.

Exploring Perceptions of Biologic Therapies: A Qualitative Study Among Canadians Living with Severe Asthma.

INTRODUCTION: Biologic therapies have demonstrated benefits for individuals with severe asthma, including reduced daily symptoms and severe exacerbations. However, data describing patient perspectives on these treatments are limited. This study sought to understand the preferences and priorities of Canadians with severe asthma in the context of novel biologic treatment options. METHODS: Semi-structured, qualitative interviews were conducted among Canadians with severe asthma from July to August 2022. Purposeful sampling included individuals with and without biologic therapy experience. All participants described daily life with severe asthma, experiences and priorities related to asthma treatment and their impressions of biologics. Reflexive thematic analysis was used to explore patterns in the data. RESULTS: Among 18 individuals included, 10 were currently taking or had prior experience with biologic treatment for asthma. Those who had never been treated with biologics were unfamiliar with them, considering treatment, or believed that they may not be eligible. Four themes were developed to convey the perspectives of participants on biologics: (1) life-changing benefits, but not for all; (2) navigating barriers to being prescribed and remaining adherent to biologic treatments; (3) treatment administration preferences are not only about convenience; (4) concerns about safety and the unknown as a source of treatment hesitancy. CONCLUSIONS: Findings suggest that the clinical benefits of biologics align with patient perceptions of achieving good asthma control. However, treatment gaps persist among individuals who do not experience a meaningful improvement in their asthma symptoms and those who face barriers accessing biologics. People with severe asthma attributed importance to greater availability of at-home treatment options, improved access to financial support to cover treatment costs and support to address safety concerns. This research provides insight into patient-based treatment priorities and preferences for biologics, which may help inform decision-making related to emerging therapies for severe asthma.

For people with severe asthma, biologics are a treatment option that can be taken in addition to their regular medication. In this study, we asked 18 Canadians with severe asthma about how having severe asthma affects their lives, their current and previous asthma treatments, and their views on biologics. Ten people in this study were currently taking or had previously taken biologics for severe asthma. We found that biologics can be life changing. Also, people with severe asthma can find it difficult to get on and stay on biologics. They would like financial and educational support when considering biologics and prefer to take biologics at home, if possible. This study helps us understand the priorities and preferences related to biologics of patients with severe asthma.

Frequency and indication of non-musculoskeletal examinations: a cross-sectional survey of Quebec chiropractors.

BACKGROUND: Approximately 1% of low back pain is estimated to be caused by serious systemic diseases, including cancer, infection, or abdominal aortic dissection. This study aimed to determine the frequency of execution of non-MSK physical examination procedures among Quebec chiropractors and to identify the clinical context that prompts them to use these physical examination procedures. METHODS: Cross-sectional survey containing 44 questions administered to a random sample of Quebec chiropractors using a succession of online, postal and phone questionnaires. The 4-part survey questionnaire contained six demographic questions, 28 single-choice questions to determine the frequency of execution of non-MSK physical examination procedures, seven short clinical vignettes for which the respondents had to select the non-MSK examinations that would be required, and two questions inquiring about the proportion of new patients for which participants' felt non-MSK examinations were necessary and whether appropriate assessments were performed. The questionnaire was pilot tested, and feedback received integrated prior to administration. We conducted descriptive statistics, Pearson correlations, and an ANOVA. RESULTS: The survey was completed by 182 chiropractors (response rate: 36.4%). The most commonly non-musculoskeletal examination performed daily were blood pressure (12.1%) and cranial nerves (4.9%). The most common tests never performed were oxygen saturation (68.7%), cardiac auscultation (69.2%), tibio-brachial index (71.4%), breast (86.8%), rectal (96.7%), testicular (95.6%), and vaginal (99.9%) exams. Female chiropractors and Quebec University in Trois-Rivières graduates reported that a significantly higher proportion of their new patients required a non-musculoskeletal physical examination compared to male participants (37.2% vs 28.3%) or Canadian Memorial Chiropractic College graduates (33.9% vs 19.9%). Reason for not performing a physical examination included the belief that another healthcare professional was better positioned to perform and/or interpret the related tests (76.4%). CONCLUSIONS: Vital signs and cranial nerve examinations were the most frequency performed non-musculoskeletal examinations reported by chiropractors. Apart from the genitourinary exam almost never performed, most participants chose non-musculoskeletal examinations deemed appropriate for the patient's presentation.

Evaluation of the Canadian approved drug screening equipment cut-off levels for tetrahydrocannabinol (THC).

In 2018, Canada introduced roadside oral fluid (OF) screening devices, called Approved Drug Screening Equipment (ADSE), as an investigative tool in impaired driving investigations to detect tetrahydrocannabinol (THC), cocaine and/or methamphetamine in drivers. In this work, we compare the detection and concentration of THC in blood samples collected from suspected impaired drivers that tested positive at the roadside for THC on an ADSE. The two ADSEs that were utilized were the Dräger DrugTest® 5000 (DDT) and the Abbott SoToxa™ (SoToxa), both configured with a THC OF concentration cut-off concentration of 25 ng/mL. Blood samples were screened for cannabinoids using immunoassay and positive results were followed up by confirmation/quantitation of THC by ultra-performance liquid chromatography with tandem mass spectrometry (UPLC-MS-MS). A total of 230 cases were available where a blood sample was collected from a suspected impaired driver subsequent to a positive THC screen result on an ADSE. The blood samples were taken an average of 1.4 hours (range = 9 minutes to 3.2 hours) after the ADSE test. THC was confirmed in 98% of blood samples with concentrations across all samples ranging from not detected (cut = off 0.5 ng/mL) to greater than 20 ng/mL. Further, 90% of the blood samples had a THC concentration of 2.0 ng/mL (the lower per se limit in Canada) or greater. A positive ADSE test of a suspected impaired driver may predict that the driver has a detectable level of THC in their blood, and there is a high likelihood that the THC blood concentration is 2.0 ng/mL or higher. Hence, ADSE may be a useful tool for law enforcement and aid in the development of grounds to believe that a driver is operating a conveyance with a THC concentration exceeding Canadian per se limits.

Assessing the Influence of Patient Empowerment Gained Through Mental Health Apps on Patient Trust in the Health Care Provider and Patient Compliance With the Recommended Treatment: Cross-sectional Study.

BACKGROUND: In chronic mental illness, noncompliance with treatment significantly worsens the illness course and outcomes for patients. Considering that nearly 1 billion people worldwide experience mental health issues, including 1 of 5 Canadians in any given year, finding tools to lower noncompliance in these populations is critical for health care systems. A promising avenue is apps that make mental health services more accessible to patients. However, little is known regarding the impact of the empowerment gained from mental health apps on patient compliance with recommended treatment. OBJECTIVE: This study aimed to investigate the impact of patient empowerment gained through mental health apps on patient trust in the health care provider and patient compliance with the recommended treatment. METHODS: A cross-sectional web-based survey was conducted in Canada. Eligible participants were Canadian adults diagnosed with chronic mental health disorders who were using at least one of the following apps: Dialogue, MindBeacon, Deprexis, Ginger, Talkspace, BetterHelp, MindStrong, Mindshift, Bloom, Headspace, and Calm. A total of 347 valid questionnaires were collected and analyzed using partial least-squares structural equation modeling. Trust in the health care provider and patient compliance were measured with multiple-item scales adapted from existing scales. Patient empowerment was conceived and measured as a higher-order construct encompassing the following 2 dimensions: patient process and patient outcome. All the items contributing to the constructs in the model were measured with 7-point Likert scales. The reliability and validity of the measurement model were assessed, and the path coefficients of the structural model were estimated. RESULTS: The results clearly show that patient empowerment gained through mental health apps positively influenced patient trust in the health care provider (ß=.306; P<.001). Patient trust in the health care provider had a positive effect on patient compliance (ß=.725; P<.001). The direct relationship between patient empowerment and patient compliance was not significant (ß=.061, P=.23). Interestingly, the data highlight that the effect of patient empowerment on patient compliance was fully mediated by trust in the health care provider (ß=.222; P<.001). The results show that patient empowerment gained through the mental health app involves 2 dimensions: a process and an outcome. CONCLUSIONS: This study shows that for individuals living with mental health disorders, empowerment gained through mental health apps enhances trust in the health care provider. It reveals that patient empowerment impacts patient compliance but only through the full mediating effect of patient trust in the health care provider, indicating that patient trust is a critical variable to enhance patient compliance. Hence, our results confirm that health care systems could encourage the use of mental health apps to favor a climate that facilitates patients' trust in health care provider recommendations, possibly leading to better compliance with the recommended treatment.

What's the big IDEA? Incorporating inclusion, diversity, equity, and access (IDEA) in population health nutrition research and practice.

Historically, the constructs of inclusion, diversity, equity, and access (IDEA) have not been sufficiently considered or included in population health nutrition research and practice. Consequently, current nutrition assessment benchmarks and knowledge translation tools may not accurately or adequately reflect diversity in the Canadian population or produce meaningful dietary guidance. The purpose of this current opinion paper is to introduce the population health nutrition research and practice framework and explore the current application of IDEA within this framework. Recommendations are offered to incorporate the constructs of IDEA along the continuum of future nutrition research and services to improve population nutritional health.

Perspectives of Canadian health leaders on the relationship between medical assistance in dying and palliative and end-of-life care services: a qualitative study.

BACKGROUND: Medical assistance in dying (MAiD) was legalized in Canada in 2016, but coordination of MAiD and palliative and end-of-life care (PEOLC) services remains underdeveloped. We sought to understand the perspectives of health leaders across Canada on the relationship between MAiD and PEOLC services and to identify opportunities for improved coordination. METHODS: In this quantitative study, we purposively sampled health leaders across Canada with expertise in MAiD, PEOLC, or both. We conducted semi-structured interviews between April 2021 and January 2022. Interview transcripts were coded independently by 2 researchers and reconciled to identify key themes using content analysis. We applied the PATH framework for Integrated Health Services to guide data collection and analysis. RESULTS: We conducted 36 interviews. Participants expressed diverse views about the optimal relationship between MAiD and PEOLC, and the desirability of integration, separation, or coordination of these services. We identified 11 themes to improve the relationship between the services across 4 PATH levels: client-centred services (e.g., educate public); health operations (e.g., cultivate compassionate and proactive leadership); health systems (e.g., conduct broad and inclusive consultation and planning); and intersectoral initiatives (e.g., provide standard practice guidelines across health care systems). INTERPRETATION: Health leaders recognized that cooperation between MAiD and PEOLC services is required for appropriate referrals, care coordination, and patient care. They identified the need for public and provider education, standardized practice guidelines, relationship-building, and leadership. Our findings have implications for MAiD and PEOLC policy development and clinical practice in Canada and other jurisdictions.

Genetic structure and population diversity of Phytophthora infestans strains in Pacific western Canada.

Late blight caused by Phytophthora infestans is an economically important disease of potato and tomato worldwide. In Canada, an increase in late blight incidence and severity coincided with changes in genetic composition of P. infestans. We monitored late blight incidence on tomato and potato in Pacific western and eastern Canada between 2019 and 2022, identified genotypes of P. infestans, and examined their population genetic diversity. We identified four major existing genotypes US11, US17, US8, and US23 as well as 25 new genotypes. The US11 genotype was dominant in Pacific western Canada, accounting for 59% of the total population. We discovered the US17 genotype for the first time in Canada. We revealed a higher incidence of late blight and quite diverse genotypes of P. infestans in Pacific western Canada than in eastern Canada. We found high genetic diversity of P. infestans population from Pacific western Canada, as evidenced by the high number of multilocus genotypes, high values of genetic diversity indices, and emergence of 25 new genotypes. Considering the number of disease incidence, the detection of diverse known genotypes, the emergence of novel genotypes, and the high number of isolates resistant to metalaxyl-m (95%) from Pacific western Canada, the region could play a role in establishing sexual recombination and diverse populations, which could ultimately pose challenges for late blight management. Therefore, continuous monitoring of P. infestans populations in Pacific western region and across Canada is warranted. KEY POINTS: • Genotypes of P. infestans in Pacific western were quite diverse than in eastern Canada. • We discovered US17 genotype for the first time in Canada and identified 26 novel genotypes. • Approximately 95% of P. infestans isolates were resistant to metalaxyl-m.

A scoping review of Indigenous community-specific physical activity measures developed with and for Indigenous Peoples in Canada, Australia, and New Zealand.

Historical factors including colonization and ongoing socioeconomic inequities impact Indigenous Peoples' ability to mitigate chronic disease risks such as achieving recommended physical activity (PA) levels. Reliably assessing, reflecting, and promoting PA participation among Indigenous Peoples may be impacted by a lack of culturally appropriate assessment methods and meaningful engagement with Indigenous communities throughout the research process. The objectives of this scoping review were to examine: (1) How PA research with Indigenous Peoples used community-specific PA measures developed with and/or for Indigenous Peoples in Canada, Australia, and New Zealand; and (2) How the studies utilized community-based participatory research (CBPR) principles to engage communities. A systematic search was conducted in four electronic databases (Web of Science, Medline, University of Saskatchewan Indigenous Portal, and ProQuest Dissertations and Theses Global). Thirty-one (n = 31) articles were identified and data extracted for narrative synthesis. Studies using community-specific PA measures have been increasing over time. Adapting questionnaires to traditional Indigenous activities such as cultural dances, ceremonies, and food-gathering activities were the most frequent adjustments undertaken to use community-specific measures. There are, however, gaps in research partnering with communities with only 6% of studies including all eight CBPR principles. Practical ways researchers can engage Indigenous communities and build capacity such as training and employing community members were highlighted. More needs to be done to facilitate community self-determination and develop long-term sustainable initiatives. Using culturally appropriate and relevant methodologies including partnering with Indigenous communities may help identification and implementation of culturally relevant and sustainable health-promoting initiatives.
