ABSTRACT
BACKGROUND: We assessed feasibility and safety of laparoscopic sigmoidectomy for complicated fistulizing diverticular disease in a tertiary care colorectal center. METHODS: A single-center retrospective study of patients undergoing sigmoidectomy for fistulizing diverticular disease between 2011 and 2021 was realized. Primary outcomes were rates of conversion to open surgery and severe postoperative morbidity at 30 days. Secondary outcomes included rates of postoperative bladder leaks on cystogram. RESULTS: Among the 104 patients, 32.7% had previous laparotomy. Laparoscopy was the initial approach in 103 (99.0%), with 6 (5.8%) conversions to laparotomy. Clavien-Dindo grade ≥ III complication rate at 30 days was 10.6%, including two (1.9%) anastomotic leaks. The median postoperative length of stay was 4.0 days. Seven (6.7%) patients underwent reoperation, six (5.8%) were readmitted, and one (0.9%) died within 30 days. Twelve (11.5%) ileostomies were created initially, and two (1.9%) were created following anastomotic leaks. At last follow-up, 101 (97.1%) patients were stoma-free. Urgent surgeries had a higher rate of severe postoperative complications. Among colovesical fistula patients (n = 73), postoperative cystograms were performed in 56.2%, identifying two out of the three bladder leaks detected on closed suction drains. No differences in postoperative outcomes occurred between groups with and without postoperative cystograms, including Foley catheter removal within seven days (73.2% vs. 90.6%, p = 0.08). CONCLUSIONS: Laparoscopic surgery for complicated fistulizing diverticulitis showed low rates of severe complications, conversions to open surgery and permanent stomas in high-volume colorectal center.

Indigenous populations have remained resilient in maintaining their unique culture and values, despite facing centuries of colonial oppression. With many discriminatory policies continuing to disempower Indigenous peoples, First Nations communities have been reported to experience a higher level of cardiovascular disease (CVD)-related mortality, compared to that in the general population. Many of the risk factors contributing to the burden of CVD have been attributed to the impact of colonization and the ongoing dismissal of Indigenous knowledge. Despite Indigenous peoples recognizing the value of addressing their mental, physical, spiritual, and emotional well-being in balanced totality, current health services focus predominantly on the promotion of Western biomedicine. To begin to move toward reconciliation, a better understanding of how Indigenous health is defined within different cultural worldviews is needed. The objective of this scoping review was to explore the various Western and/or Indigenous strategies used for the prevention of CVD and the management of heart health and wellness in Indigenous communities in Canada. In this review, a total of 3316 articles were identified, and only 21 articles met the eligibility criteria. Three major themes emerged, as follows: (i) valuing of the emotional domain of health through cultural safety; (ii) community is at the core of empowering health outcomes; and (iii) bridging of cultures through partnership and mutual learning. Most studies recognized the importance of community engagement to develop heart health strategies that integrate traditional languages and cultures. However, to move toward the delivery of culturally safe care, health systems need to rebuild their relationship with Indigenous peoples.
Les populations autochtones ont toujours fait preuve de résilience dans le maintien de leurs cultures et de leurs valeurs uniques, malgré des siècles d'oppression coloniale. En raison des nombreuses politiques discriminatoires qui continuent de priver les peuples autochtones de certains pouvoirs, on rapporte que les communautés des Premières Nations ont un taux de mortalité liée aux maladies cardiovasculaires (MCV) supérieur à celui observé dans la population générale. De nombreux facteurs de risque qui contribuent au fardeau des MCV ont été attribués aux répercussions de la colonisation et au rejet continu du savoir autochtone. Malgré le fait que les peuples autochtones reconnaissent l'avantage de prendre soin de leur bien-être mental, physique, spirituel et émotionnel dans une intégralité équilibrée, les services de santé actuels sont essentiellement axés sur la promotion de la biomédecine occidentale. Afin de commencer à nous diriger vers la réconciliation, nous devons mieux comprendre la façon dont les peuples autochtones définissent la santé au sein de différentes visions culturelles du monde. L'objectif de cette étude de portée était d'explorer les diverses stratégies occidentales ou autochtones de prévention des MCV et de prise en charge de la santé et du bien-être cardiaques chez les communautés autochtones du Canada. Dans le cadre de cette étude, 3 316 articles ont été recensés, et seulement 21 d'entre eux répondaient aux critères de sélection. Trois principaux thèmes ont été dégagés, soit : (i) la sécurité culturelle permet de mettre en avant l'importance du domaine émotionnel de la santé; (ii) la communauté est au centre de l'autonomie en matière de devenir de la santé; et (iii) le lien entre les cultures doit se faire au moyen de partenariats et d'apprentissages mutuels. La plupart des études reconnaissaient l'importance de l'engagement communautaire pour mettre au point des stratégies relatives à la santé du cÅur qui intègrent les langues et les cultures traditionnelles. Toutefois, afin de passer à la prestation de soins respectueux des cultures, les systèmes de santé doivent reconstruire leur relation avec les peuples autochtones.
ABSTRACT
Cardiovascular disease is a leading cause of death worldwide, with disproportionate impacts on Indigenous Peoples in Canada. In Spring 2022, a land-based learning program was piloted and evaluated as an Indigenous cultural safety training for professionals at a cardiac care centre and university in a large urban city. Baseline and endline surveys showed an increase in knowledge of Indigenous histories, cultures, and practices; increased reflection on positionality and intention to create change; and strengthened relationships with the land. Future work should explore the long-term effects of land-based cultural safety training on participant behaviours, and health outcomes for Indigenous Peoples.

Background: Indigenous people have displayed their strength through their holistic practices and spiritual connection to the land. Despite overcoming the impact of discriminatory and disempowering policies within Western institutions, Indigenous people continue to experience a higher risk of cardiovascular disease, compared to the general population. To move toward improving Indigenous health outcomes, researchers need to work in partnership with communities to develop heart health strategies centred on their experienced barriers and sources of healing. We conducted a community-based explorative study in Moosonee, Ontario to explore the local community's needs and priorities regarding heart health and wellness. Methods: A convenience sample of community members and healthcare professionals were invited to participate in a sharing circle. Qualitative data were analyzed using conventional content analysis and the Indigenous method of two-eyed seeing. Results: Eight community members and 5 healthcare professionals participated in the sharing circle. Four dominant themes were identified: (1) heart health is more than metrics; (2) honouring our traumas; (3) destigmatizing care through relationship building; and (4) innovative solutions start with community. With the history of mistreatment among Indigenous people, strength-based solutions involved rebuilding clinical relationships. To bring care closer to home, digital health tools were widely accepted, but the design of these tools needs to integrate both Western and Indigenous approaches to healing. Conclusions: Indigenous health upholds the physical, emotional, psychological, and spiritual needs of an individual as being of equal importance. To improve community heart health, strategies should start by strengthening broken bonds and bridging multiple worldviews of healing.
Contexte: Les peuples autochtones tirent une grande force de leurs pratiques holistiques et de leur lien spirituel avec le territoire, et même s'ils ont surmonté les répercussions des politiques discriminatoires et marginalisantes des institutions occidentales, ils présentent encore un risque de maladies cardiovasculaires supérieur à celui de la population générale. Afin d'aider à améliorer la santé cardiovasculaire des Autochtones, les chercheurs doivent travailler avec les communautés pour mettre en place des stratégies qui tiennent compte des obstacles en matière de soins de santé et des méthodes de guérison traditionnelles. Nous avons réalisé une étude exploratoire en milieu communautaire à Moosonee (Ontario) dans le but d'explorer les besoins et les priorités de la communauté locale en matière de santé cardiovasculaire et de bien-être. Méthodologie: Des membres de la communauté et des professionnels de la santé ont été invités à participer à un cercle de partage. Les données qualitatives ont été analysées au moyen d'une analyse classique et de la méthode autochtone dite à double perspective. Résultats: Huit membres de la communauté et cinq professionnels de la santé ont participé au cercle de partage. Quatre principaux thèmes ont été abordés : 1) la santé cardiovasculaire va au-delà de ce qui se mesure; 2) il faut tenir compte des traumatismes; 3) il faut déstigmatiser les soins en nouant des relations et 4) les solutions novatrices doivent reposer sur la participation de la communauté. En raison du passé de maltraitance envers les peuples autochtones, les solutions axées sur les forces devaient permettre de restaurer la confiance envers les soins cliniques. Les outils de santé numérique, bien adaptés aux besoins de la communauté, ont été largement acceptés, mais ils doivent intégrer les méthodes de soins occidentales et autochtones. Conclusions: Selon la vision autochtone, la santé repose en parts égales sur les aspects physiques, émotionnels, psychologiques et spirituels d'une personne. L'amélioration de la santé cardiovasculaire des membres de la communauté passe donc avant tout par des stratégies qui permettent de recréer les liens qui ont été brisés et qui intèrent plusieurs visions thérapeutiques.
ABSTRACT
Background: The COVID-19 pandemic has reduced access to endomyocardial biopsy (EMB) rejection surveillance in heart transplant (HT) recipients. This study is the first in Canada to assess the role for noninvasive rejection surveillance in personalizing titration of immunosuppression and patient satisfaction post-HT. Methods: In this mixed-methods prospective cohort study, adult HT recipients more than 6 months from HT had their routine EMBs replaced by noninvasive rejection surveillance with gene expression profiling (GEP) and donor-derived cell-free DNA (dd-cfDNA) testing. Demographics, outcomes of noninvasive surveillance score, hospital admissions, patient satisfaction, and health status on the medical outcomes study 12-item short-form health survey (SF-12) were collected and analyzed, using t tests and χ2 tests. Thematic qualitative analysis was performed for open-ended responses. Results: Among 90 patients, 31 (33%) were enrolled. A total of 36 combined GEP/dd-cfDNA tests were performed; 22 (61%) had negative results for both, 10 (27%) had positive GEP/negative dd-cfDNA results, 4 (11%) had negative GEP/positive dd-cfDNA results, and 0 were positive on both. All patients with a positive dd-cfDNA result (range: 0.19%-0.81%) underwent EMB with no significant cellular or antibody-mediated rejection. A total of 15 cases (42%) had immunosuppression reduction, and this increased to 55% in patients with negative concordant testing. Overall, patients' reported satisfaction was 90%, and on thematic analysis they were more satisfied, with less anxiety, during the noninvasive testing experience. Conclusions: Noninvasive rejection surveillance was associated with the ability to lower immunosuppression, increase satisfaction, and reduce anxiety in HT recipients, minimizing exposure for patients and providers during a global pandemic.
Contexte: La pandémie de COVID-19 a réduit l'accès à la biopsie endomyocardique pour surveiller le risque de rejet après une greffe du cÅur. Cette étude est la première à être menée au Canada pour évaluer le rôle de la surveillance non invasive du risque de rejet en personnalisant le titrage de l'immunosuppression et la satisfaction du patient après la greffe cardiaque. Méthodologie: Dans le cadre de cette étude de cohorte prospective à méthodes mixtes, des adultes ayant reçu une greffe cardiaque depuis plus de six mois ont vu leurs biopsies endomyocardiques régulières remplacées par une surveillance non invasive du risque de rejet qui consiste à établir le profil de l'expression génique et à analyser l'ADN acellulaire dérivé du donneur. Les données démographiques, les résultats du score de surveillance non invasive, les admissions à l'hôpital, la satisfaction des patients et l'état de santé tirés du questionnaire SF-12 (questionnaire abrégé sur la santé comprenant 12 items) de l'étude sur les issues médicales ont été colligés et analysés au moyen des tests T et des tests χ2. Les réponses ouvertes ont fait l'objet d'une analyse qualitative thématique. Résultats: Parmi 90 patients, 31 (33 %) ont été recrutés. Au total, 36 tests combinés de profilages de l'expression génique et d'ADN acellulaire dérivé du donneur ont été réalisés; les résultats ont été négatifs pour les deux tests dans 22 cas (61 %), positifs pour le profilage de l'expression génique et négatifs pour l'ADN acellulaire dans 10 cas (27 %), négatifs pour le profilage de l'expression génique et positifs pour l'ADN acellulaire dans quatre cas (11 %) et aucun cas n'a donné de résultats positifs pour les deux types de tests. Tous les patients qui ont donné des résultats positifs à l'analyse de l'ADN acellulaire dérivé du donneur (fourchette : 0,19 % à 0,81 %) ont subi une biopsie endomyocardique n'ayant révélé aucun rejet cellulaire ou à médiation par anticorps important. Au total, 15 cas (42 %) affichaient une immunosuppression réduite, proportion qui a grimpé à 55 % chez les patients dont les tests de concordance ont donné des résultats négatifs. Dans l'ensemble, le niveau de satisfaction rapporté par les patients était de 90 % et, à l'analyse thématique, ils étaient plus satisfaits et moins anxieux pendant les tests non invasifs. Conclusions: La surveillance non invasive du risque de rejet a été associée à la capacité de diminuer l'immunosuppression, d'augmenter la satisfaction et de réduire l'anxiété chez les patients qui ont reçu une greffe cardiaque, en plus de réduire l'exposition des patients et du personnel médical dans le contexte d'une pandémie.
ABSTRACT
INTRODUCTION: Heart failure (HF) symptoms improve through self-care, for which adherence remains low among patients despite the provision of education for these behaviours by clinical teams. Open Access Digital Community Promoting Self-Care, Peer Support and Health Literacy (ODYSSEE-vCHAT) combines automated digital counselling with social network support to improve mortality and morbidity, engagement with self-care materials, and health-related quality of life. METHODS AND ANALYSIS: Use of ODYSSEE-vCHAT via Internet-connected personal computer by 162 HF patients will be compared with a control condition over 22 months. The primary outcome is a composite index score of all-cause mortality, all-cause emergency department visits, and HF-related hospitalisation at trial completion. Secondary outcomes include individual components of the composite index, engagement with self-care materials, and patient-reported measures of physical and psychosocial well-being, disease management, health literacy, and substance use. Patients are recruited from tertiary care hospitals in Toronto, Canada and randomised on a 1:1 ratio to both arms of the trial. Online assessments occur at baseline (t=0), months 4, 8 and 12, and trial completion. Ordinal logistic regression analyses and generalised linear models will evaluate primary and secondary outcomes. ETHICS AND DISSEMINATION: The trial has been approved by the research ethics boards at the University Health Network (20-5960), Sunnybrook Hospital (5117), and Mount Sinai Hospital (21-022-E). Informed consent of eligible patients occurs in person or online. Findings will be shared with key stakeholders and the public. Results will allow for the preparation of a Canada-wide phase III trial to evaluate the efficacy of ODYSSEE-vCHAT in improving clinical outcomes and raising the standard of outpatient care. TRIAL REGISTRATION NUMBER: NCT04966104.

BACKGROUND: Given the context-specific nature of health research prioritization and the obligation to effectively allocate resources to initiatives that will achieve the greatest impact, evaluation of priority setting processes can refine and strengthen such exercises and their outcomes. However, guidance is needed on evaluation tools that can be applied to research priority setting. This paper describes the adaption and application of a conceptual framework to evaluate a research priority setting exercise operating within the public health sector in Ontario, Canada. METHODS: The Nine Common Themes of Good Practice checklist, described by Viergever et al. (Health Res Policy Syst 8:36, 2010) was used as the conceptual framework to evaluate the research priority setting process developed for the Locally Driven Collaborative Projects (LDCP) program in Ontario, Canada. Multiple data sources were used to inform the evaluation, including a review of selected priority setting approaches, surveys with priority setting participants, document review, and consultation with the program advisory committee. RESULTS: The evaluation assisted in identifying improvements to six elements of the LDCP priority setting process. The modifications were aimed at improving inclusiveness, information gathering practices, planning for project implementation, and evaluation. In addition, the findings identified that the timing of priority setting activities and level of control over the process were key factors that influenced the ability to effectively implement changes. CONCLUSIONS: The findings demonstrate the novel adaptation and application of the 'Nine Common Themes of Good Practice checklist' as a tool for evaluating a research priority setting exercise. The tool can guide the development of evaluation questions and enables the assessment of key constructs related to the design and delivery of a research priority setting process.

We have previously reported the synthesis of VP-128, a new 17beta-oestradiol (E(2))-linked platinum(II) hybrid with high affinity for oestrogen receptor alpha (ERalpha). In the present study, we have investigated the anti-tumour activity of VP-128 towards breast cancer cells in vitro and in vivo. We used human ERalpha-positive (MCF-7) and -negative (MDA-MB-468) cells as a model for treatment with increasing doses of VP-128, cisplatin or E(2) in vitro and for xenograft experiments in nude mice in vivo. Compared with cisplatin, VP-128 showed markedly improved in vitro and in vivo anti-tumour activity towards ERalpha-positive MCF-7 breast cancer cells, without increased systemic toxicity. In these caspase-3-deficient cells, treatment with VP-128 overcame weak cellular sensitivity to cisplatin in vitro and in vivo. In these cells, only the hybrid induced apoptosis in an ERalpha-dependent manner, inactivated both X-linked inhibitor of apoptosis protein and Akt, and induced selective nuclear accumulation of ERalpha and the expression of ER-regulated genes c-myc and tff1, which was blocked by ERalpha-specific antagonist ICI 282 780. In the case of ERalpha-negative MDA-MB-468 cells, VP-128, but not cisplatin, induced nuclear accumulation of apoptosis-inducing factor and inhibited c-myc expression. However, VP-128 did not show enhanced in vivo anti-tumour activity compared with cisplatin. These results reveal two different modes of action for VP-128 in ERalpha-positive and -negative breast cancer cells, and highlight the promising therapeutic value of this unique E(2)-platinum hybrid for selective targeting of hormone-dependent cancers.
