Our aim in this study was to identify how to improve diabetic retinopathy screening from the perspectives of people with type 2 diabetes and health-care professionals and to elicit their thoughts on initiatives to increase attendance.

Previous reviews have highlighted the efficacy of lifestyle diabetes prevention programs (DPPs) in decreasing type 2 diabetes (T2D) risk; however, the participating population is predominantly white. This is concerning as ethnically diverse populations are disproportionately affected by T2D. The objective of this scoping review was to 1) summarize existing tailored DPPs and 2) provide recommendations for future program implementation to improve access and reach for diverse populations.

The aim of the study was to compare cardiac and respiratory function at rest in participants with early-onset type 2 diabetes and a control group without diabetes, matched for age, sex, and body mass index (BMI).

Indigenous peoples in Canada are considered the highest risk populations for type 2 diabetes mellitus (T2DM). Quality improvement (QI) strategies may be considered effective interventions for improving T2DM health outcomes. The purpose of this study was to understand experiences associated with implementation of the SOAR QI program to improve prevention and management of T2DM.

Activating transcription factor 4 (ATF4) and mean amplitude of glycemic excursion (MAGE) have been implicated in the pathogenesis of osteoporosis (OP) and type 2 diabetes mellitus (T2DM). In this retrospective cohort study we assessed the predictive value of serum ATF4 and MAGE for occurrence of OP in patients with T2DM.

Women with gestational diabetes (GDM) are advised to undergo an oral glucose tolerance test (OGTT) within 6-months postpartum, owing to their elevated risk of developing pre-diabetes/diabetes. However, the optimal approach to glycemic surveillance in the years thereafter is unclear. We thus sought to compare OGTT and A1C for chronic monitoring of women with previous GDM.

In type 2 diabetes (T2D), formation of toxic protein aggregates named amyloid in pancreatic islets contributes to islet inflammation, and beta-cell dysfunction and death, by promoting IL-1beta production and activation of the Fas-mediated apoptotic pathway. Islet macrophages are the main source of amyloid-induced IL-1beta production. We examined the effects of amyloid formation on pro-inflammatory (M1) and anti-inflammatory (M2) islet macrophages.

Addressing the disproportionate rates of type 2 diabetes (T2D) among Indigenous peoples in Canada requires innovative, community-engaged efforts. Through a multi-phase study, our team of researchers, clinicians, Knowledge Keepers, people with Indigenous living experience, and community representatives is collaboratively developing strategies for promoting health and wellness among Indigenous youth with an aim to prevent T2D. The overall research purpose is to co-design culturally-informed, community-specific educational resources that support healthy living and T2D prevention among youth.

In 2022, the FDA approved the anti-CD3 immunotherapy teplizumab to delay symptomatic type 1 diabetes (T1D), although the mechanism involved remains unclear. Evidence shows some β cells escape death and instead undergo senescence during T1D. This study aimed to determine whether anti-CD3, which mitigates β-cell destruction by cytotoxic T cells, also impacts senescent β-cell accumulation during T1D.

Latent autoimmune diabetes of adults (LADA), characterized by gradual autoimmune destruction of beta cells that spans between type 1 and type 2 diabetes, currently lacks a comprehensive assessment for diabetes distress.

Endothelial dysfunction, central to the development of chronic diabetic complications, often manifests in the form of endothelial-to-mesenchymal transition (EndMT), where endothelial cells lose their endothelial properties and adopt mesenchymal-like phenotypes. miR-9 is a key regulator of glucose-induced EndMT in the retina and heart, however, the relation between high glucose and miR-9 suppression remains unclear. We hypothesized that despite playing a key role in EndMT in both organs, the regulatory linkage between high glucose and miR-9 inhibition differ between the retina and heart.

Patient decision aids (PtDAs) are evidence-based interventions designed to help patients make informed health decisions aligned with their values and preferences. The aim of this sub-analysis was to evaluate the effectiveness of PtDAs for adults facing diabetes-related screening, prevention, and treatment decisions.

Diabetes disproportionately affects Indigenous communities in Canada, with higher prevalence rates and severe complications. Historical trauma, socio-economic disparities, and inappropriate health-care practices compound these challenges. This case study examines the model of care of the Indigenous Diabetes Health Circle (IDHC) and its impact on Indigenous communities in Ontario. After obtaining internal ethical approval, a researcher immersed themselves within the IDHC for 6 months, observing frontline worker-client interactions and videos, and documenting the organization's culturally safe practices, utilizing ethnographic methods.

Regular physical activity (PA) benefits those with type 1 diabetes (T1D), yet many are below recommended activity levels. This study aimed to assess knowledge and barriers to PA in the T1D population using an online questionnaire.

In Canada, Indigenous (First Nation, Métis, and Inuit) children and youth are experiencing an epidemic of type 2 diabetes (T2D). Given the prevalence of pediatric T2D and its impact on Indigenous youth and their families, effective culture-based interventions are urgently needed to promote improved health outcomes. The purpose of this research project is to co-create culture-based T2D education interventions among youth. In this presentation, we describe the findings outlining the Knowledge Keepers and adult participants’ conceptions of hope with respect to health promotion and T2D prevention which are providing the foundation for co-developing education interventions.

Incretin receptor agonists, including GLP1, are used extensively to treat type 2 diabetes, and restore both insulin secretion and sensitivity. To explore how GLP1 agonism impacts islet β-cell Ca2+ dynamics in vivo, we engrafted islets expressing the calcium indicator GCaMP6f into the anterior eye chamber (ACE) of control, diet- or genetically-induced hyperglycemic mice. Following engraftment (21 weeks-post-surgery), islet Ca2+ was monitored by confocal imaging through the front of the eye in anesthetized animals at days 0, 1, and 7.

Diabetic cardiomyopathy (DCM) is a common complication of diabetes that can lead to heart failure. In this study, we investigated mechanisms through which cell death occurs in cultured H9c2 cardiomyoblasts treated with high glucose (25 mM). We examined the cardioprotective effects of the adiponectin receptor agonist, ALY688, and the mechanisms through which the protective effects are exerted, namely attenuation of inflammation and induction of autophagy. Western blot to detect caspase-3 showed a significant increase in cleaved caspase-3 levels following 24-hour treatment under high-glucose conditions compared to normal glucose, indicating activation of apoptosis in H9c2 cells.

Obesity-related heart disease is associated with metabolic remodeling and defective organelle function in the cardiomyocyte. Transcription factor EB (TFEB) is the bona fide regulator of lysosomal function. Fatty acid overload depletes TFEB, perturbing lysosomal function. We tested the hypothesis that a decline in cardiomyocyte TFEB during diet-induced obesity (DIO) remodels energy metabolism and triggers cardiac dysfunction. Wild type (TFEBfl/fl -/-) and cardiomyocyte TFEB knockout (TFEBfl/fl Cre/-) mice were fed low-fat (LF;10 kcal% from fat) or high-fat (HF; 60 kcal% from fat) diet for 20 weeks.
