Can laboratory HIV and infectious syphilis data inform future pre-exposure prophylaxis use in women in Ontario, Canada?

OBJECTIVES: Infectious syphilis has been proposed as an indication for HIV pre-exposure prophylaxis (PrEP) in women. We explored how many women experienced HIV seroconversion after being diagnosed with syphilis in Ontario between 20 April 2010 and 31 December 2021. METHODS: Through deterministic linkage of laboratory data at the Public Health Ontario laboratory, which conducts the vast majority of syphilis and HIV testing in Ontario, we quantified the number of females with positive syphilis diagnoses who subsequently exhibited HIV seroconversion between April 2010 and December 2021. New HIV cases were identified by diagnostic serology or HIV viral load test result of ≥20 copies/mL at least 60 days after the positive syphilis test. We report aggregate numbers of women with new laboratory evidence of HIV infection after their first positive syphilis test. RESULTS: Among 7957 women with positive syphilis tests during the study period, 6554 (82.4%) had linkable HIV serology tests and 133 (1.7%) ever tested HIV positive. With further linkage to viral load data, the number of women who ever had laboratory evidence of HIV infection increased to 184 (2.3%). However, when restricting to women whose first positive HIV test or HIV viral load occurred after their first positive syphilis test, this number decreased to 34 (0.4%). The median (IQR) time between the positive syphilis test and the first laboratory evidence of HIV was 551 (IQR=226-1159) days. CONCLUSION: Although it is clinically appropriate to recommend HIV PrEP to women with syphilis, Ontario surveillance data suggest that the population-level impact of this strategy on the HIV epidemic in Ontario would have been modest during this 11-year period. Future studies should explore additional ways of prioritising women for PrEP.

Understanding the perspective of community co-educators on community-based service learning: a qualitative analysis.

Background: Community-based service learning (CBSL) is a core component of the Canadian medical education system. However, the unique role of community partner organizations (CPOs) in supporting CBSL remains unclear. This qualitative study evaluates the perspective of CPOs as co-educators in the undergraduate medical curriculum. Methods: We conducted eight semi-structured, one-on-one interviews with CPOs at a medical school in Toronto, Ontario between 2020-2021. Interviews were conducted following a pre-determined interview guide and then recorded, de-identified, and transcribed. Three reviewers independently performed an inductive thematic analysis of codes followed by a group review of discrepancies. Results: Five main findings were identified: 1) CPOs share a common interest in serving as co-educators; 2) considerable heterogeneity in the understanding of co-education exists; 3) there is an opportunity for increased partnerships between CPOs and faculty; 4) the role of co-educators is limited by curriculum structure; and 5) co-educators facilitate unique teachings of social determinants of health otherwise not available through traditional didactic teaching. Conclusions: There is an emerging, unique role for community co-educators in the undergraduate medical curriculum, supported by interest from CPOs. Its emphasis may contribute to future cohorts of medical students capable of understanding and addressing the needs of the populations they serve.

Contexte: L'apprentissage par le service communautaire (APSC) est une composante essentielle du système d'éducation médicale canadien. Cependant, le rôle unique des organismes communautaires partenaires (OCP) dans le soutien de l'APSC n'est toujours pas clair. Cette étude qualitative évalue le point de vue des OCP en tant que co-éducateurs dans le programme d'études médicales de premier cycle. Méthodes: Nous avons mené huit entrevues individuelles semi-structurées avec des OCP d'une faculté de médecine de Toronto, en Ontario, entre 2020 et 2021. Les entrevues ont été menées en suivant un guide d'entrevue prédéterminé, puis enregistrées, dépersonnalisées et transcrites. Trois examinateurs ont effectué indépendamment une analyse thématique inductive des codes, suivie d'un examen collectif des divergences. Résultats: Cinq conclusions principales ont été identifiées : 1) les OCP ont un intérêt commun à agir en tant que co-éducateurs; 2) il existe une grande hétérogénéité dans la compréhension de la co-éducation; 3) il est possible d'accroître les partenariats entre les OCP et le corps professoral; 4) le rôle des co-éducateurs est limité par la structure du curriculum médical et 5) les co-éducateurs facilitent des opportunités d'apprentissage uniques sur les déterminants sociaux de la santé qui ne sont pas disponibles dans le cadre de l'enseignement didactique traditionnel. Conclusions: Les co-éducateurs communautaires jouent un rôle novateur et unique dans le programme d'études médicales de premier cycle, soutenu par l'intérêt des OCP. L'accent mis sur ce rôle peut contribuer à former de futures cohortes d'étudiants en médecine capables de comprendre et de répondre aux besoins des populations qu'ils servent.

Indigenous Food Systems Changes and Resiliency: Protocol for a Scoping Review.

BACKGROUND: Indigenous food systems (IFS) consider the complex relationships and connections between land, animals, plants, water, and people. These food systems may differ between regions, Indigenous cultures, and history; however, given the similar colonial histories and policies influencing Indigenous groups in Canada, the United States, Australia, and Aotearoa (New Zealand), the IFS changes and responses in these regions may follow similar trends. Climate change and pollution continue to impact the environment in catastrophic ways, and this, in turn, impacts IFS. However, to date, there has been no review of the literature on IFS, how they are changing, and how communities are responding to these changes. OBJECTIVE: In this scoping review, we will summarize primary research in Canada, the United States, Australia, and Aotearoa related to IFS addressing the following questions: (1) What changes are IFS experiencing in the context of climate change and pollution? (2) What actions have been taken in response to IFS changes? (3) What are the characteristics of IFS research in peer-reviewed academic literature? METHODS: We will use the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines for scoping reviews and the Joanna Briggs Institute reviewer's manual to inform the review process. MEDLINE, SCOPUS, International Bibliography of the Social Sciences, Sociological Abstracts, and the Bibliography of Native North Americans are the databases included in this review search. All screening and extraction have been supported by Covidence software (Veritas Health Innovation) with 2 independent reviewers conducting the abstract and full-text screening. We will map concepts and themes related to the research questions to contribute to the understanding of IFS within the academic literature and provide a narrative review of the outcomes. RESULTS: The electronic database searches for this review were conducted in May 2021. Screening and full-text review were initially completed in the winter of 2022. We are currently in the process of compiling results and aim to share findings in 2023. CONCLUSIONS: This review will provide valuable insight into current IFS needs by summarizing the peer-reviewed literature on how IFS are changing because of climate change and pollution and how communities are responding to these changes. The results of this review will be shared with Indigenous communities, through academic publications, community conversations, and conference presentations.

Advocacy in community-based service learning: perspectives of community partner organizations.

Background: Health advocacy is a core competency for physicians, which can be developed through community-based service-learning (CBSL). This exploratory study investigated the experiences of community partner organizations (CPOs) participating in CBSL in the context of health advocacy. Methods: A qualitative study was conducted. Nine CPOs at a medical school participated in interviews on topics pertaining to CBSL and health advocacy. Interviews were recorded, transcribed, and coded. Major themes were identified. Results: CPOs perceived a positive impact from CBSL through student activities and connecting with the medical community. There was no unifying definition of health advocacy. Advocacy activities varied depending on the individual's role (i.e., CPO, physician, and student), which encompassed providing patient care or services, raising awareness of healthcare issues, and influencing policy changes. CPOs had different perceptions of their role in CBSL from facilitating service-learning opportunities to teaching students in CBSL, while a few desired to be involved in curriculum development. Conclusion: This study provides further insight into health advocacy from the lens of CPOs, which may inform changes to health advocacy training and the CanMEDS Health Advocate Role to better align with the values of community organizations. Engaging CPOs in the broader medical education system may improve health advocacy training and ensure a positive bidirectional impact.

Contexte: La promotion de la santé est une compétence fondamentale pour les médecins, qui peux être développée dans le cadre de l'apprentissage par le service communautaire (ASC). Cette étude exploratoire examine les expériences des organismes communautaires partenaires (OCP) participant à l'ASC en ce qui concerne le volet promotion de la santé. Méthodes: Dans le cadre d'une étude qualitative, neuf OCP d'une faculté de médecine ont participé à des entretiens sur des sujets liés à l'ASC et à la promotion de la santé. Les entretiens ont été enregistrés, transcrits et codés, et les thèmes principaux en ont été extraits. Résultats: Les OCP ont perçu un effet positif de l'ASC, notamment par le biais des activités étudiantes et des liens établis avec la communauté médicale. Nous n'avons pas relevé de définition commune de la promotion de la santé. Les activités s'y rapportant varient selon le rôle de la personne (OCP, médecin ou étudiant) et comprennent la prestation de soins ou de services aux patients, la sensibilisation aux enjeux de santé et la promotion de changements d'orientations politiques. Les divers OCP avaient des perceptions différentes de leur rôle dans l'ASC, allant d'offrir des activités d'apprentissages aux étudiants en ASC, au désir de participer à l'élaboration des programmes d'études. Conclusion: Cette étude permet de mieux saisir le point de vue des OCP sur la promotion de la santé. Elle peut ainsi éclairer les révisions du rôle CanMEDS de promoteur de la santé et de la formation en la matière de façon à les aligner davantage sur les valeurs des organismes communautaires. L'intégration des OCP à la formation médicale au sens large pourrait contribuer à améliorer le volet promotion de la santé de cette dernière et profiter aux partenaires de part et d'autre.
