Cannabinoids Used for Medical Purposes in Children and Adolescents: A Systematic Review and Meta-Analysis.

Importance: Cannabinoids are increasingly used for medical purposes in children. Evidence of the safety of cannabinoids in this context is sparse, creating a need for reliable information to close this knowledge gap. Objective: To study the adverse event profile of cannabinoids used for medical purposes in children and adolescents. Data Sources: For this systematic review and meta-analysis, MEDLINE, Embase, PsycINFO, and the Cochrane Library were searched for randomized clinical trials published from database inception to March 1, 2024, for subject terms and keywords focused on cannabis and children and adolescents. Search results were restricted to human studies in French or English. Study Selection: Two reviewers independently performed the title, abstract, and full-text review, data extraction, and quality assessment. Included studies enrolled at least 1 individual 18 years or younger, had a natural or pharmaceutical cannabinoid used as an intervention to manage any medical condition, and had an active comparator or placebo. Data Extraction and Synthesis: Two reviewers performed data extraction and quality assessment independently. The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guideline and PRISMA-S guideline were used. Data were pooled using a random-effects model. Main Outcomes and Measures: The primary outcome was the incidence of withdrawals, withdrawals due to adverse events, overall adverse events, and serious adverse events in the cannabinoid and control arms. Secondary outcomes were the incidence of specific serious adverse events and adverse events based on organ system involvement. Results: Of 39 175 citations, 23 RCTs with 3612 participants were included (635 [17.6%] female and 2071 [57.3%] male; data not available from 2 trials); 11 trials (47.8%) included children and adolescents only, and the other 12 trials (52.2%) included children, adolescents, and adults. Interventions included purified cannabidiol (11 [47.8%]), nabilone (4 [17.4%]), tetrahydrocannabinol (3 [13.0%]), cannabis herbal extract (3 [13.0%]), and dexanabinol (2 [8.7%]). The most common indications were epilepsy (9 [39.1%]) and chemotherapy-induced nausea and vomiting (7 [30.4%]). Compared with the control, cannabinoids were associated with an overall increased risk of adverse events (risk ratio [RR], 1.09; 95% CI, 1.02-1.16; I2 = 54%; 12 trials), withdrawals due to adverse events (RR, 3.07; 95% CI, 1.73-5.43; I2 = 0%; 14 trials), and serious adverse events (RR, 1.81; 95% CI, 1.21-2.71; I2 = 59%; 11 trials). Cannabinoid-associated adverse events with higher RRs were diarrhea (RR, 1.82; 95% CI, 1.30-2.54; I2 = 35%; 10 trials), increased serum levels of aspartate aminotransferase (RR, 5.69; 95% CI, 1.74-18.64; I2 = 0%; 5 trials) and alanine aminotransferase (RR, 5.67; 95% CI, 2.23-14.39; I2 = 0%; 6 trials), and somnolence (RR, 2.28; 95% CI, 1.83-2.85; I2 = 8%; 14 trials). Conclusions and Relevance: In this systematic review and meta-analysis, cannabinoids used for medical purposes in children and adolescents in RCTs were associated with an increased risk of adverse events. The findings suggest that long-term safety studies, including those exploring cannabinoid-related drug interactions and tools that improve adverse event reporting, are needed.

Exploring the ability of ChatGPT to create quality patient education resources about kidney transplant.

BACKGROUND: Chat Generative Pre-trained Transformer (ChatGPT) is a language model that may have the potential to revolutionize health care. The study purpose was to test whether ChatGPT could be used to create educational brochures about kidney transplant tailored for three target audiences: caregivers, teens and children. METHODS: Using a list of 25 educational topics, standardized prompts were employed to ensure content consistency in ChatGPT generation. An expert panel assessed the accuracy of the content by rating agreement on a Likert scale (1 = <25 % agreement; and 5 = 100 % agreement). The understandability, actionability and readability of the brochures were assessed using the Patient Education Materials Assessment Tool for printable materials (PEMAT-P) and standard readability scales. A caregiver and patient reviewed and provided written feedback. RESULTS: We found mean understandability scores of 69 %, 66 %, and 73 % for caregiver, teen, and child brochures respectively, with 90.7 % of the ChatGPT generated brochures scoring 40 % on the actionability scale. Generated caregiver and teen materials achieved readability levels of grades 9-14, while child-specific brochures achieved readability levels of grades 6-11. Brochures were formatted appropriately but lacked depth. CONCLUSION: ChatGPT demonstrates potential for rapidly generating patient education materials; however, challenges remain in ensuring content specificity. We share the lessons learned to assist other healthcare providers with using this technology.

Video Education and Behavior Contract to Improve Outcomes After Renal Transplantation (VECTOR): A Randomized Controlled Trial.

Sub-optimal adherence to immunosuppressant medications reduces graft survival for kidney transplant recipients and adherence-enhancing interventions are resource and time intensive. We performed a multi-center randomized controlled trial to investigate the impact of an electronically delivered intervention on adherence. Of 203 adult kidney transplant recipients who received a de novo kidney transplant n = 173 agreed to participate (intent-to-treat population) and were randomized to the intervention (video education plus behavior contract n = 91) or the control (standard education, n = 82). No significant differences were found between the groups for medication adherence measured by the Basel Assessment of Adherence to Immunosuppressive Medications Scale, intrapatient variability in tacrolimus levels, time in therapeutic range for any immunosuppressant, knowledge, self-efficacy, QOL, or hospitalizations. Among a subgroup of 64 participants randomized to the intervention group who completed a post-intervention questionnaire, two-thirds (67%, n = 43) reported watching at least 80% of the videos and 58% (n = 37) completed the electronic goal setting exercise and adherence contract. An autonomous goal setting exercise and electronic behavioural contract added to standard of care did not improve any outcomes. Our findings reiterate that nonadherence in transplantation is a difficult multifactorial problem that simple solutions will not solve. Trial registration number NCT03540121.

Removing barriers to accessing medical cannabis for paediatric patients.

Medical cannabis (MC) may offer therapeutic benefits for children with complex neurological conditions and chronic diseases. In Canada, parents, and caregivers frequently report encountering barriers when accessing MC for their children. These include negative preconceived notions about risks and benefits, challenges connecting with a knowledgeable healthcare provider (HCP), the high cost of MC products, and navigating MC product shortages. In this manuscript, we explore several of these barriers and provide recommendations to decision-makers to enable a family-centered and evidence-based approach to MC medicine and research for children.

Electronic health record-enabled routine assessment of medication adherence after solid organ transplantation: the time is now.

Medication nonadherence after solid organ transplantation is recognized as an important impediment to long-term graft survival. Yet, assessment of adherence is often not part of routine care. In this Personal Viewpoint, we call for the transplant community to consider implementing a systematic process to screen and assess medication adherence. We believe acceptable tools are available to support integrating adherence assessments into the electronic health record. Creating a standard assessment can be done efficiently and cost-effectively if we come together as a community. More importantly, such monitoring can improve outcomes and strengthen provider-patient relationships. We further discuss the practical challenges and potential rebuttals to our position.

Updates in Kidney Transplantation From the 2022 Banff-Canadian Society of Transplantation Joint Meeting: Conference Report.

Purpose of the Conference: The 2022 Banff-Canadian Society of Transplantation Meeting in Banff, Alberta, brought together transplant professionals to review new developments across various aspects of solid organ transplantation (SOT) in Canada. Sources of Information: Presentations included consensus recommendations from expert-led forums; experiences with new procedures and legislation; reports from public health data repositories; original clinical and laboratory research; and industry updates regarding novel technologies. Speakers referenced articles and reports published in peer-reviewed journals and online, and unpublished data and preliminary findings. Methods: All authors attended presentations in-person or virtually. Recordings of select presentations were available for later review. Summaries emphasize concepts indicated by speakers as new and clinically relevant. Key Findings: The COVID-19 pandemic disproportionately affected solid organ transplant recipients (SOTRs), who experience worse outcomes of COVID-19 infection than the general population. Vaccinations demonstrate an attenuated immunological response in SOTRs yet provide meaningful protection. Monoclonal antibodies are effective for both passive immunization and treatment of COVID-19 in SOTRs. Infection control protocols have driven the development of virtual methods for clinical research, such as using home blood draws and virtual follow-up to evaluate vaccine efficacy in SOTRs; and patient care delivery, such as employing telerehabilitation post transplant. Access to living kidney donation is limited by various disincentives experienced by potential donors, which may be overcome by more efficient evaluations including a One-Day Living Kidney Donor Assessment Clinic. The International Donation and Transplantation Legislative and Policy Forum provided a means of establishing consensus guidance for organ donation and transplantation (ODT) program policy to standardize delivery across jurisdictions. The implementation of a deemed consent model for organ and tissue donation in Nova Scotia may provide insight as to whether this model indeed improves access to organs. Canada's Indigenous population experiences unique barriers to transplantation, prompting efforts for more inclusive ODT policy-making. The Pan-Canadian ODT Data and Performance Reporting System Project has defined performance quality indicators, of which iTransplant and other point-of-care software solutions may facilitate collection; however, these endeavors ultimately require information technology infrastructure that exceeds the capabilities of the existing Canadian Organ Replacement Register and Canadian Transplant Registry. Pig-to-human xenotransplantation requires genetic modification of pigs and xenoantibody testing in recipients but may yet prove viable. Serum cell-free DNA, urine biomarkers, and genetic markers offer an alternative to routine biopsy for identifying subclinical rejection. Modified perfusion temperatures and perfusion solutions with hydrogen sulfide donor compounds may improve organ preservation. Molecular compatibility tools provide another means of improving SOTR outcomes, and the Genome Canada Transplant Consortium has been examining important considerations of their implementation. Limitations: We were unable to capture all presentations and topics at the meeting due to the sizable quantity and variety. Topics ultimately excluded from this summary include those in pathology including Banff Classification updates; those unique to extra-renal SOT; as well as numerous abstract and poster presentations, allied health provider forums, and business meetings. A portion of the material was presented by speakers prior to peer-review or publication. Implications: The various conference presentations summarized in this report identify methods by which individual clinicians and provincial ODT programs may improve access, delivery, and quality of SOT care in Canada, while additionally identifying gaps in the literature that investigators are encouraged to pursue.

Objectifs de la conférence: En 2022, le congrès annuel de la Société canadienne de transplantation qui s'est tenu à Banff (Alberta) a réuni des professionnels de la transplantation qui se sont penchés sur les nouveaux développements dans divers aspects de la transplantation d'organes solides (TOS) au Canada. Sources: Les présentations portaient notamment sur : les recommandations consensuelles issues de forums dirigés par des experts; l'expérience avec les nouvelles procédures et lois; des rapports provenant de dépôts de données de santé publique; des recherches cliniques et des recherches de laboratoire originales; et les mises à jour du secteur sur les nouvelles technologies. Les intervenants ont fait référence à des articles et rapports publiés en ligne et dans des revues évaluées par les pairs, ainsi qu'à des données non publiées et des conclusions préliminaires. Méthodologie: Tous les auteurs ont assisté aux présentations en personne ou virtuellement. Les enregistrements de certaines présentations étaient disponibles pour visionnement ultérieur. Les résumés mettent l'accent sur les concepts jugés comme nouveaux et cliniquement pertinents par les intervenants. Principaux résultats: La pandémie de COVID-19 a affecté les receveurs d'une transplantation d'organe solide (RTOS) de manière disproportionnée; ces derniers ayant suivi une évolution plus défavorable que la population générale à la suite d'une infection à la COVID-19. La vaccination, bien qu'elle offre une protection significative, montre une réponse immunologique plus faible chez les RTOS. Les anticorps monoclonaux sont efficaces à la fois pour l'immunization passive et le traitement de la COVID-19 chez les RTOS. Les protocoles de contrôle des infections ont mené au développement de méthodes virtuelles pour la recherche clinique (p. ex. prélèvements sanguins à domicile, suivi virtuel pour évaluer l'efficacité du vaccin chez les RTOS) et la prestation de soins aux patients (p. ex. rééducation à distance) après la transplantation. L'accès au don de rein vivant est limité par divers facteurs dissuasifs pour les donneurs potentiels, mais ces obstacles peuvent être surmontés par des évaluations plus efficaces, notamment par une clinique d'un jour pour évaluer la candidature des donneurs vivants de rein. Le Forum législatif et politique international sur le don et la transplantation a fourni un moyen d'établir des lignes directrices consensuelles pour la politique du program de dons d'organes et de transplantation (DOT), dans l'objectif de normaliser la prestation d'une juridiction à l'autre. La mise en œuvre en Nouvelle-Écosse du consentement présumé pour le don d'organes et de tissus pourrait aider à déterminer si un tel modèle améliore effectivement l'accès aux organes. Les populations autochtones du Canada sont confrontées à des obstacles uniques en matière de transplantation, ce qui encourage les efforts visant l'élaboration de politiques plus inclusives en matière de DOT. Le Projet de système pancanadien de données et de mesure de la performance pour les DOT a défini des indicateurs de performance, dont iTransplant et d'autres solutions logicielles pour les points de soins, qui peuvent faciliter la collecte des données; ces derniers nécessitent toutefois une infrastructure informatique qui dépasse les capacités du Registre canadien des insuffisances et des transplantations d'organes et du Registre canadien de transplantation. La xénogreffe de porc à humain requiert une modification génétique des porcs et le dépistage de xénoanticorps chez les receveurs, mais elle peut encore s'avérer viable. L'ADN acellulaire sérique, les biomarqueurs urinaires et les marqueurs génétiques offrent une alternative à la biopsie de routine pour identifier les rejets subcliniques. Des températures de perfusion modifiées et des solutions de perfusion contenant des composés générateurs de sulfure d'hydrogène peuvent améliorer la conservation des organes. Les outils de compatibilité moléculaire offrent un autre moyen d'améliorer les résultats des RTOS, et le Genome Canada Transplant Consortium a examiné les aspects importants à prendre en considération pour leur mise en œuvre. Limites: Nous n'avons pas été en mesure d'assister à toutes les présentations en raison du grand nombre et de la grande diversité des sujets abordés. Les sujets exclus de ce résumé incluent la pathologie, notamment les mises à jour de la classification Banff; les sujets propres à la TOS extrarénale; ainsi que de nombreux résumés et présentations d'affiches, forums de prestataires de soins de santé alliés et réunions d'affaires. Une partie du matériel présenté l'a été avant l'examen par les pairs ou la publication. Conclusion: Les présentations du congrès qui sont résumées dans le présent rapport identifient les méthodes que les programs provinciaux de DOT et les cliniciens pourraient employer pour améliorer l'accès, la prestation et la qualité des soins en TOS au Canada, et soulignent des lacunes dans la littérature que les chercheurs sont encouragés à creuser.

The development of a Cannabis Knowledge Assessment Tool (CKAT).

BACKGROUND: Misconceptions about the health risks of cannabis remain prevalent, indicating the need to improve public health messaging and determine the effectiveness of educational programming. Our objective was to develop a standardized questionnaire to measure knowledge about cannabis in the context of cannabis legalization. METHODS: A Cannabis Knowledge Assessment Tool (CKAT) was created using the Delphi method. A purposive sample of healthcare professionals, policymakers, academics, patients, and students served as the content and development experts. Principal component analysis from the codes identified from open-ended feedback guided the item development. Upon completion, the CKAT was administered as a pre- and post-test in four schools (7th and 9th Grade) in Canada. The data were analysed to determine whether knowledge scores changed after participating in a cannabis education program. RESULTS: Twenty-four experts initially participated in the Delphi process and 18 (75% retention) continued throughout. Principal component analysis identified 3 domains: 1) effects of cannabis on the individual, 2) general information about cannabis, and 3) cannabis harm reduction. The final questionnaire consisted of 16 multiple-true-false questions (64 items) and received a Flesch-Kincaid Grade Level of 6.3, and a SMOG index score of 7.6. The CKAT was completed by 132 students; seventy-three 7th grade and fifty-nine 9th grade students. The baseline mean CKAT score was 46.2 (SD:5.5), which increased to 50.7 (SD:4.6) after the cannabis educational program (p<0.05). CONCLUSIONS: A novel tool to measure knowledge of cannabis was developed and piloted in 7th grade and 9th grade students. Future studies are required to test usability and validity of the CKAT in other contexts.

A scoping review of pediatric transplant education.

BACKGROUND: Education is crucial for pediatric patients and caregivers throughout the transplant continuum, yet data are lacking around which interventions are effective and in what circumstances. METHODS: We undertook a scoping review with the objectives of (a) describing the types, effects, and outcomes of patient-focused educational interventions before and after pediatric transplant and (b) understanding the educational experiences of patients and caregivers. Five scientific databases were explored for relevant literature using the JBI methodology. Educational interventions published in English, targeting pediatric solid organ transplant patients (0-25 years) and their caregivers were included. Relevant data from eligible articles (n = 27) were extracted and summarized. RESULTS: Eighteen articles describing 17 educational interventions were identified for objective A, and nine articles qualitatively assessing patient or parental learning needs were identified for objective B. Most interventions were directed toward teenage patients and their caregivers post kidney transplant, primarily focusing on medication self-management and adherence, or providing general information on transplant using multicomponent delivery formats. Most interventions achieved statistically significant improvements in knowledge (n = 8/9) and patients or caregivers expressed satisfaction with the intervention (n = 7/7) but health-related outcomes such as medication adherence (n = 2/6) or behavior change (n = 1/3) rarely achieved statistically significant results. In objective B, patients and caregivers described the transplant process as overwhelming, but indicated that social supports and education helped them cope. Participants consistently wanted more information than they received. CONCLUSION: Caregivers and pediatric patients value transplant education, but high-quality studies are limited. Since education is a fundamental part of the transplant process, future research in this area should be prioritized.

Medical cannabis in schools: A qualitative study on the experiences of clinicians.

Objectives: Guidance is lacking for medical cannabis use in Canadian schools in both legislation and approach; the impact of ambiguous policy on patient care is unknown. A qualitative study was undertaken to explore the experiences of clinicians who care for school-aged children who take medical cannabis. Methods: Semi-structured interviews were recorded and transcribed verbatim. Qualitative content analysis performed using the Dedoose qualitative software ascribed meaning units and codes, which were further consolidated into categories and subcategories. Results: Thirteen physicians were interviewed virtually, representing seven provinces in Canada. The physicians provided care for between five and hundreds of school-aged children who took medical cannabis. The most common indications were refractory seizure disorders and autism. The interviews provided rich descriptions on perceptions of medical cannabis in schools, and in general. Five overarching categories were identified across both domains including variability, challenges (subcategories: lack of knowledge, stigma, lack of policy, and pragmatic challenges), potential solutions (subcategories: treat it like other medications, communication, education, and family support), positive experiences and improvements over time. Conclusion: In Canada, cannabis-based medicine use in schools still faces important challenges. Effective education, communication, family support and policy refinements that allow cannabis to be treated like other prescription medications are recommended to improve the status quo. These findings will guide the C4T Medical Cannabis in Schools Working Group's future priorities and initiatives.

Medical cannabis in schools: The experiences of caregivers.

Objectives: Implementing medical cannabis (MC) into a child's daily routine can be challenging and there is a lack of guidance for its therapeutic use in schools in Canada. Our objective was to learn about the experiences of caregivers of school-aged children who require MC. Methods: Qualitative description was used and caregivers were interviewed about MC in schools and in general. The transcripts were entered into Dedoose software for qualitative analysis and content analysis was performed. Sentences and statements were ascribed line by line into meaning units and labelled with codes, and organized according to categories and subcategories. Results: Twelve caregivers of school-aged children who take MC participated. The most common reasons for treatment were drug-resistant epilepsy (DRE), autism, or other developmental disorders. Approximately half of the participants' children (n = 6) took MC during the school day and most (5/6) perceived their experiences to be positive or neutral but reported a lack of knowledge about MC. While data saturation was not reached regarding MC in schools, rich dialogues were garnered about MC in general and three categories were identified: challenges (subcategories stigma, finding an authorizer, cost, dosing, and supply); parents as advocates (subcategories required knowledge, attitudes, skills, and sources of information); and caregiver relief for positive outcomes. Conclusions: Caregivers demonstrate remarkable tenacity despite the many challenges associated with MC use. Education and practice change are needed to ensure that children using MC can benefit from or continue to experience its positive outcomes within the school environment and beyond.

Medical Cannabis in Canadian Schools: A Scoping Review of Existing Policies.

Objective: An increasing number of children and youth in Canada are taking medical cannabis for complex medical conditions. While they deserve safe and consistent access to pharmacotherapy throughout the day, administrative policies on cannabis use in schools are inconsistent. A scoping review identified policies and publications associated with medical cannabis in Canadian schools. Methods: Five databases (Scopus, PubMed, CINAHL, EMBASE, and Web of Science) were searched to identify scientific literature. Legislation in each province and territory and Ministry of Education webpages were reviewed for pertinent laws and policies regarding cannabis use in schools. Results: The scientific search resulted in 1289 articles. The five included articles pertain to implications for school nurses in the United States, which are not relevant to the Canadian context. A search of Ministry of Education websites identified only one policy with information regarding medical cannabis in schools (from Ontario). Federal legislation (the Cannabis Act) does not specifically address medical cannabis in schools, and there is a lack of consistency in terminology and clarity within provincial and territorial laws. All provinces and territories prohibit smoking and vaping of cannabis on school property and some provinces prohibit any method of cannabis consumption. Conclusions: In Canada, there is a lack of guidance for medical cannabis administration, storage, and disposal in schools, with some policies explicitly prohibiting this type of treatment. This shifts the burden to families to individually create plans school by school. A federally harmonized approach to supporting children who take cannabis for medical purposes ought to be explored.

Concerns, beliefs and attitudes of pharmacists and pharmacy students on cannabis use in Canada.

Background: Since cannabis has been legalized in Canada for medical and recreational use, there has been an increased demand on pharmacists for cannabis counselling. The objective of this study was to determine the concerns, beliefs and attitudes of Canadian pharmacists and pharmacy students towards using cannabis. Methods: An online survey was synthesized under 3 broad themes: concerns, beliefs and attitudes about cannabis, consisting of 27 questions capturing demographics and Likert scale responding to survey questions. We examined whether there were differences in responses by geographic location (i.e., Ontario, Quebec, Canada), sex or practice setting (i.e., community, hospital). Results: Across Canada, there were 654 survey respondents, with 399 in Ontario and 95 in Quebec. Approximately 24% indicated they had used cannabis since legalization, 69% indicated they believed cannabis should be available for medical and recreational use and 34% indicated their perceptions towards cannabis had become more positive since legalization. Relative to Quebec or the rest of Canada, respondents from Ontario were significantly more likely to be comfortable providing counselling to and answering questions of patients on the safety and efficacy of medical cannabis use. Examining sex differences across Canada, male respondents were more comfortable than female counselling patients on the safety and efficacy of medical cannabis. Conclusion: The current results reinforce the perceived need by pharmacists and pharmacy students for targeted education, and future research in cannabis education should consider potential gender differences in attitudes and beliefs surrounding cannabis therapy.

Ranking of Curricular Content by Pharmacy Students and Community Pharmacists.

A cross-sectional survey was conducted to determine the relative rankings of 17 key components in an undergraduate program. The degree of discrepancy between curricular content and that of student and pharmacist expectations was also of interest. An online questionnaire was emailed to both groups in one Canadian province. Respondents considered four questions related to the nature and adequacy of education they did receive (pharmacists) or should receive (students) and the relative importance of key topic areas (along 11-point scales). The response rate was 31.0 (students) and 10.8 percent (pharmacists). As expected, both students and pharmacists identified therapeutics and patient counselling as critical focal points for the program, while the importance of compounding was mixed. Most topics were deemed as best handled during the didactic program, with students seeing greater value in learning a larger portion of two skills (injection training and managerial duties) post-graduation. In conclusion, discrepancies were indeed found. For students, topics such as injection training and minor ailment prescribing were perceived as receiving too little attention, while communication, pharmaceutical sciences, and professionalism received too much attention. In a significant departure in perspective, pharmacists rated communication, ethical decision-making, and professionalism almost two points higher than did students.

A Mixed Methods Assessment of Home-Based Video Pretransplant Lung Education.

Introduction: Patients awaiting lung transplantation must learn new information to successfully navigate the transplant process. A supplemental video series was piloted to patients at home during the Covid-19 pandemic to improve pre-transplant education. Methods: A mixed methods study was undertaken to assess patient experiences with this method of education, confirm the ideal timing of the education, and identify gaps that require further attention. Semi-structured interviews were conducted with 17 one-on-one or dyadic (patients and caregivers) who viewed the video series at home. A third-party researcher (not involved in creation of the educational materials) conducted the interviews by phone, which were audio recorded and then transcribed verbatim. NVivo 12 Pro for Windows software was used to code the data and identify emerging themes. Results: Participants indicated that home-based videos were applicable, and informative and helpful (4.7 on 5-point Likert scale) and appreciated the advice and experiences of real patients. They were satisfied with their transplant education (4.2/5). While there were few aspects that the participants disliked about the videos, the interviews elicited outstanding questions about the transplant process (eg, logistical aspects of travel) and transplant concerns (eg, medications, expenses, and precautions in daily life). Conclusion: Patients being assessed or listed for lung transplant valued the novel electronic video education, and we will implement the home-based process into standard of care after the patient's initial visit with the transplant respirologist. Pre-transplant education will be tailored to help address the outstanding gaps identified in this program evaluation.

Waitlisted and Transplant Patient Perspectives on Expanding Access to Deceased-Donor Kidney Transplant: A Qualitative Study.

Background: A concerning number of kidneys (eg, expanded donor criteria, extended criteria, or marginal kidneys) are discarded yearly while patients experience significant morbidity and mortality on the transplant waitlist. Novel solutions are needed to solve the shortage of kidneys available for transplant. Patient perceptions regarding the use of these less than ideal kidneys remain unexplored. Objective: To explore the perspectives of patients who have previously received a less than ideal kidney in the past and patients awaiting transplant who could potentially benefit from one. Design: Qualitative description study. Setting: 2 provinces in Canada participated (Saskatchewan and Manitoba). Patients: Patients with end-stage kidney disease who were awaiting kidney transplant and were either (a) aged 65 years and older, or (b) 55 years and older with other medical conditions (eg, diabetes). Methods: Criterion sampling was used to identify participants. Semi-structured, one-on-one interviews were conducted virtually, which explored perceived quality of life, perceptions of less than ideal kidneys, risk tolerance for accepting one, and educational needs to make such a choice. The interviews were transcribed verbatim and thematic analysis was used to analyze the data. Results: 15 interviews were conducted with usable data (n = 10 pretransplant; n = 5 posttransplant). Participants were a mean of 65.5 ± 8.8 years old. Four interrelated themes became prominent including (1) patient awareness and understanding of their situation or context, (2) a desire for information, (3) a desire for freedom from dialysis, and (4) trust. Subthemes of transparency, clarity, standardization, and autonomy were deemed important for participant education. The majority of pretransplant participants (n = 8/10) indicated that between 3 and 5 years off of dialysis would make the risk of accepting a less than ideal kidney feel worthwhile. Limitation: The study setting was limited to 2 Canadian provinces, which limits the generalizability. Furthermore, the participants were homogenous in demographics such as ethnicity. Conclusion: These findings indicate that patients are comfortable to accept a less than ideal kidney for transplant in situations where their autonomy is respected, they are provided clear, standardized, and transparent information, and when they trust their physician. These results will be used to inform the development of a new national registry for expanding access to deceased-donor kidney transplant. Trial Registration: Not registered.

Contexte: De nombreux reins sont rejetés chaque année (donneurs à critères élargis, critères étendus ou reins marginaux), alors que les patients qui attendent une greffe présentent une morbidité importante et un taux de mortalité élevé. De nouvelles solutions sont nécessaires pour contrer la pénurie de reins disponibles pour une transplantation. Les perceptions des patients quant à l'utilization de ces reins moins idéaux restent inexplorées. Objectif: Explorer les perceptions des patients ayant reçu un rein moins idéal dans le passé et des patients en attente d'une greffe qui pourraient potentiellement bénéficier d'un tel don. Conception: Étude qualitative et descriptive. Cadre: Deux provinces canadiennes (Saskatchewan et Manitoba). Participants: Des patients atteints d'insuffisance rénale terminale en attente d'une transplantation (a) âgés de 65 ans et plus ou (b) âgés de 55 ans et plus et présentant d'autres problèmes de santé (ex. diabète). Méthodologie: L'échantillonnage avec critères a été utilisé pour identifier les participants. Des entretiens individuels semi-structurés menés virtuellement ont exploré la qualité de vie perçue, la perception quant aux reins moins idéaux, la tolérance à l'égard des risques inhérents à l'acceptation d'un tel rein, et les besoins d'information pour faire ce choix. Les entrevues ont été transcrites intégralement et l'analyze des données a été réalisée par analyze thématique. Résultats: Quinze entrevues avec données utilisables ont été menées (n = 10 avant la greffe; n = 5 après la greffe). Les participants avaient en moyenne 65.5 ± 8.8 ans. Quatre thèmes interreliés ont été dégagés : (1) la sensibilisation et la compréhension des patients quant à leur situation ou au contexte; (2) le besoin d'information; (3) le besoin d'un congé de dialyze; et (4) la confiance envers le médecin. La transparence, la clarté, la normalization et l'autonomie ont été jugées comme des sous-thèmes importants de l'éducation des participants. Pour la majorité des participants en attente d'une greffe (n = 8/10), l'idée d'un congé de 3 à 5 ans de dialyze rendrait acceptables les risques associés à l'acceptation d'un rein moins idéal. Limites: Étude tenue dans deux provinces canadiennes, ce qui limite la généralisabilité des résultats. Homogénéité des participants sur le plan démographique, notamment en ce qui concerne l'origine ethnique. Conclusion: Les résultats indiquent que les patients seraient à l'aise d'accepter un rein moins idéal pour une greffe, pourvu que leur autonomie soit respectée, qu'ils reçoivent des informations claires, standardisées et transparentes, et qu'ils aient confiance en leur médecin. Ces résultats serviront à éclairer l'élaboration d'un nouveau registre national afin d'élargir l'accès à la transplantation de rein provenant de donneurs décédés. Enregistrement de l'essai: Non enregistré.

Pharmacokinetics of apixaban and tacrolimus or cyclosporine in kidney and lung transplant recipients.

Apixaban is frequently used off-label in transplant recipients. However, a potential drug interaction exists with the calcineurin inhibitors. We conducted an open-label drug-drug interaction study to determine the pharmacokinetics of apixaban in lung and kidney transplant recipients who were taking a calcineurin inhibitor. A single dose of apixaban 10 mg was administered orally to kidney and lung transplant recipients maintained on either tacrolimus or cyclosporine, and pharmacokinetic parameters were compared to a reference cohort of 12 healthy subjects who used the same apixaban dose and pharmacokinetic blood sampling. Fourteen participants were enrolled (n = 6 kidney, n = 8 lung), with 10 maintained on tacrolimus and four on cyclosporine. Data from 13 participants was usable. Participants were taking triple therapy immunosuppression and had a mean (SD) of 12 (3) medications. Participants receiving tacrolimus and cyclosporine had area under the plasma concentration-time curve from time zero to infinity (AUC0-inf ) geometric least square means (90% confidence interval [CI]) of 4312 (95% CI 3682, 5049) and 5388 (95% CI 3277, 8858), respectively. Compared to healthy subjects, the associated geometric mean ratios (GMRs) for apixaban maximum plasma concentration (Cmax ), AUC from time zero to the last quantifiable concentration (AUC0-tlast ) and AUC0-inf were 197% (95% CI 153, 295), 244% (95% CI 184, 323), and 224% (95% CI 170, 295) for transplant recipients on tacrolimus. The GMR (90% CI) Cmax , AUC0-tlast , and AUC0-inf of apixaban for patients on cyclosporine were 256% (95% CI 184, 358), 287% (95% CI 198, 415), and 280% (95% CI 195, 401). Kidney and lung transplant recipients receiving tacrolimus had higher apixaban exposure. A similar trend was noted for patients receiving cyclosporine, but additional patients are needed to confirm this interaction. Future studies are needed before apixaban can be safely recommended in this population, and the impact of dose staggering should be investigated. This study highlights the importance of pharmacokinetic studies in actual patient populations.

Cannabis for the Treatment of Attention Deficit Hyperactivity Disorder: A Report of 3 Cases.

Attention deficit hyperactivity disorder (ADHD) is a chronic neurobehavioral disorder that is highly prevalent in children and adults. An increasing number of patients with ADHD are self-medicating with cannabis, despite a lack of evidence on efficacy and safety. This case report describes 3 males (ages 18, 22, and 23) who have integrated cannabis into their treatment regimen with positive results. Semistructured interviews conducted with the patients describe subjective improvements in symptoms and on quality of life. Improvements on validated rating scales conducted post-cannabis initiation, compared to pre-cannabis initiation obtained from the medical chart, corroborated their personal accounts. Scores on the PHQ-9 (measuring depression) improved by 8-22 points (30-81%), and the SCARED (measuring anxiety) ranged from 0 to 27 points (up to 33%). Improvements on the CEER-9 scale (measuring regulation) ranged from 2 to 7 points (22-78%), and the 9-item SNAP scale (measuring inattention) showed improvements of 2-8 points (7-30%). Mild adverse events including short-term memory problems, dry mouth, and sleepiness were reported. Blood samples were also collected from the patients to determine the plasma concentrations of the cannabinoids and relevant metabolites before and after a cannabis administration. After cannabis use, the plasma levels for CBD and THC ranged from 0 to 15.29 ng/mL and 1.32 to 13.76 ng/mL, respectively. Cannabinoids, however, were not detected prior to dosing, suggesting that cannabis played a complimentary role in the therapeutic regimen of these 3 patients. Clinical trials are recommended to confirm the efficacy of cannabis in the treatment of ADHD.

Pharmacokinetics and Perceptions of Children and Young Adults Using Cannabis for Attention-Deficit/Hyperactivity Disorder and Oppositional Defiant Disorder: Protocol for a Mixed Methods Proof-of-Concept Study.

BACKGROUND: Despite the lack of evidence on the use of cannabis for the treatment of attention-deficit/hyperactivity disorder (ADHD), the growing perception that cannabis is safe has led more patients and caregivers to self-medicate. Some psychiatrists now authorize medicinal cannabis for patients with ADHD with features of oppositional defiant disorder (ODD) to curtail the unregulated (ie, self-medicated) use of recreational cannabis or to offer a therapeutic option to those who continue to experience symptoms after exhausting all other treatment options. OBJECTIVE: This protocol aims to explore the perceived effectiveness and pharmacokinetics of cannabis in youth and young adults, who are currently taking it as part of their treatment plan for ADHD with features of ODD, under the supervision of a psychiatrist. METHODS: Patients between the ages of 12 and 25 years with a diagnosis of ADHD and features of ODD, who are currently taking cannabis herbal extract (at a Δ9-tetrahydrocannabinol [THC]:cannabidiol [CBD] ratio of 1:20) as a treatment adjunct to stimulant pharmacotherapy will be recruited. A sample size of 10-20 individuals is estimated. The study interview will consist of (1) validated symptom rating scales (Swanson, Nolan, and Pelham-IV Questionnaire [SNAP-IV], 90-item; Patient Health Questionnaire, 9-item [PHQ-9]; and Screen for Child Anxiety Related Emotional Disorders [SCARED] tool to measure symptoms of ADHD and ODD, depression, and anxiety, respectively); (2) a semistructured interview to probe the experiences of using cannabis; and (3) a cannabis side effects survey. A cannabis product sample as well as 2 blood samples (a trough level and 2-hour postdose level) will be collected to measure plasma concentrations of cannabinoids and relevant metabolites (THC, CBD, 11-hydroxy-THC, 7-hydroxy-CBD, cannabichromene, and 11-nor-9-carboxy-THB) using liquid chromatography-tandem mass spectrometry (LC-MS/MS). Self-report rating scales (SNAP-IV, SCARED, and PHQ-9) will be scored in accordance with standard protocols and compared to retrospective scores obtained from the participant's chart. Demographic variables (age, weight, and race), symptom scores, and blood levels (peaks and troughs) of THC, CBD, cannabichromene (CBC), and metabolites will be summarized using descriptive statistics. Relationships between plasma concentrations and symptom scores will be determined using analysis of variance, and multiple regression analysis will be performed to determine associations between plasma concentrations and demographic variables (age, weight, and ethnicity). The qualitative data will be audio-recorded and transcribed and organized into themes. RESULTS: The protocol was approved by the Biomedical Research Ethics Board at the University of Saskatchewan (protocol #1726), and recruitment began in May 2021. CONCLUSIONS: This proof-of-concept study will explore the potential treatment effectiveness of medical cannabis in participants with ADHD and ODD through a mixed methods approach to inform future research in this area.

A Randomized Controlled Trial of a Pretransplant Educational Intervention in Kidney Patients.

Poor patient knowledge about transplantation is a significant problem following kidney transplant. A video-based educational intervention was developed to supplement standard education provided by transplant teams. METHODS: A multicenter randomized controlled trial tested the intervention delivered to patients undergoing assessment or waitlisted for kidney transplant. Adult participants were randomized to the control (standard education) or the intervention group, consisting of electronic access to the videos (or digital video disks if no internet) plus standard education. Differences between groups in changes in transplant knowledge (measured by the Kidney Transplant Understanding Tool), education satisfaction, self-efficacy, and quality of life (secondary outcomes) were evaluated by a preintervention and postintervention survey. Video viewing habits were tracked and described for patients in the intervention group. RESULTS: One hundred sixty-two patients were enrolled, with 132 completing both questionnaires (n = 64 intervention and n = 68 control), with similar enrollment from 3 Canadian sites. Video viewing statistics in the complete cases indicated that 78% (50/64) watched the videos, with 70% (45/64) viewing them electronically, while 8% (5/64) received digital video disks and self-reported participation. Baseline knowledge scores in the intent-to-treat population were 55.4 ± 6.5 and 55.7 ± 7.1 in the intervention and control, respectively. The mean knowledge change in the intervention (2.1 ± 3.6) was significantly higher than in the control group (0.8 ± 3.4, P < 0.02). In the per-protocol analysis (patients with objective evidence of watching at least 80% of the videos), the knowledge improvements were 3.4 ± 3.8. Video group participants reported higher satisfaction with education (P < 0.02) and expressed positive comments in open-ended feedback. CONCLUSIONS: Electronic video education in the pretransplant setting improved knowledge and satisfaction.

Establishing a baseline of interprofessional education perceptions in first year health science students.

Interprofessional education (IPE) is increasingly utilized to prepare students for their future careers in the health sciences as collaborative practitioners. Although it is considered an accreditation requirement in most health science disciplines, little is known about first year student's perceptions of IPE in Canada. In September of 2018, students from dentistry, kinesiology, medicine, nursing, nutrition, pharmacy, and physiotherapy in their first year of their professional program at the University of Saskatchewan were surveyed to obtain a baseline of perspectives and attitudes toward IPE. The survey consisted of an adaptation of the Readiness for Interprofessional Learning Scale (RIPLS) and additional questions to assess students' skills and interest in IPE. Descriptive and univariate statistics were used to determine associations with demographic variables. The response rate was 88% (n= 509). Health science students in all disciplines had positive perceptions of IPE, with overall mean RIPLS scores for domain 1 (teamwork and collaboration), 2 (professional identity), and 3 (roles and responsibilities) of 40.5/45, 33.3/40 and 6.3/10, respectively. Students in kinesiology had significantly lower RIPLS scores than other health science disciplines (p< .05). Female gender, and having a past degree, or previous experience with interprofessional collaboration through school or work were traits that were associated with statistically significantly higher RIPLS scores (p< .05).
