Walking in two worlds with type 2 diabetes: a scoping review of prevention and management practices incorporating traditional indigenous approaches.

Type 2 diabetes is a complex chronic disease rapidly increasing among young people and disproportionately impacting Indigenous youth. Treatment programs are often inadequate for this population as they lack cultural relevance. A scoping review was conducted to explore traditional Indigenous approaches for diabetes prevention and management, to inform a program aimed at supporting Indigenous youth and families with type 2 diabetes. We seek to answer the following question: "Which traditional medicines and practices have been incorporated into intervention or prevention strategies for Indigenous people living with diabetes?" Search was done June 2021 using Ovid Medline, ESBCO and ProQuest databases. Terms included wellbeing, intervention, diabetes, and traditional approaches. Of the 2138 titles screened, 34 met inclusion criteria. Three studies integrated traditional Indigenous approaches into Western-based intervention programming. Content included traditional food and nutrition programs, gardening programs, Elder knowledge sharing, story telling, talking circles, feasting, prayer, traditional dancing, hunting, and school-based wellness curricula. Many were wholistic, co-created with community, Indigenous-led and held in accessible community spaces. The heterogeneity in approaches reflects the diversity of Indigenous nations and communities. This review identifies important elements to include in culturally relevant programs to address diabetes-related wellness.

Impact of a screen, triage and treat program for identifying chronic disease risk in Indigenous children.

BACKGROUND: The First Nations Community Based Screening to Improve Kidney Health and Prevent Dialysis project was a point-of-care screening program in rural and remote First Nations communities in Manitoba that aimed to identify and treat hypertension, diabetes and chronic kidney disease. The program identified chronic disease in 20% of children screened. We aimed to characterize clinical screening practices before and after intervention in children aged 10-17 years old and compare outcomes with those who did not receive the intervention. METHODS: This observational, prospective cohort study started with community engagement and followed the principles of ownership, control, access and possession (OCAP). We linked participant data to administrative data at the Manitoba Centre for Health Policy to assess rates of primary care and nephrology visits, disease-modifying medication prescriptions and laboratory testing (i.e., glycosylated hemoglobin [HbA1c], estimated glomerural filtration rate [eGFR] and urine albumin- or protein-to-creatinine ratio). We analyzed the differences in proportions in the 18 months before and after the intervention. We also conducted a 1:2 propensity score matching analysis to compare outcomes of children who were screened with those who were not. RESULTS: We included 324 of 353 children from the screening program (43.8% male; median age 12.3 yr) in this study. After the intervention, laboratory testing increased by 5.8% (95% confidence interval [CI] 1.1% to 10.1%) for HbA1c, by 9.9% (95% CI 4.2% to 15.5%) for eGFR and by 6.2% (95% CI 2.3% to 10.0%) for the urine albumin- or protein-to-creatinine ratio. We observed significant improvements in laboratory testing in screened patients in the group who were part of the program, compared with matched controls. INTERPRETATION: Chronic disease surveillance and care increased significantly in children after the implementation of a point-of-care screening program in rural and remote First Nation communities. Interventions such as active surveillance programs have the potential to improve the chronic disease care being provided to First Nations children.

A Holistic Approach to Risk for Early Kidney Injury in Indigenous Youth With Type 2 Diabetes: A Proof of Concept Paper From the iCARE Cohort.

BACKGROUND: Indigenous youth with type 2 diabetes (T2D) are disproportionately affected by early onset albuminuria and are at high risk of kidney failure in early adulthood. Traditional biological approaches have failed to fully explain the renal morbidity seen in this population. The improving renal Complications in Adolescents with type 2 diabetes through REsearch cohort (iCARE) study was therefore designed in collaboration with patients, to more holistically evaluate risk factors for renal morbidity. We hypothesize that both biological factors and mental health influence renal outcomes, mediated via inflammatory pathways. OBJECTIVE: The objective of this study was to evaluate the iCARE analytic framework which evaluates relationships between biological factors, mental health, inflammation, and albuminuria utilizing a structural equation modeling (SEM) approach. METHODS: The first 187 youth with T2D (10-25 years) from the Manitoba iCARE cohort are presented here to evaluate our theoretical and analytic framework. An SEM was chosen to evaluate the statistical significance of proposed associations. The primary outcome was a nonorthostatic urine albumin:creatinine ratio ≥2 mg/mmol. Main exposures (ie, latent factors) included psychological health (distress, perceived stress, positive mental health and resilience), hypertension (24 hour monitored), and inflammatory markers (C-reactive protein [CRP], erythrocyte sedimentation rate [ESR], fibrinogen). Hemoglobin A1c (HbA1c) and duration of diabetes were covariates. RESULTS: Within the initial cohort (median age = 15 years, duration of diabetes = 2.3 years, 66.8% female), 30.5% (n = 57) had nonorthostatic albuminuria (ALB), and the majority of ALB was persistent (confirmed in 2/3 samples over a 6-month period; n = 47). Youth with ALB had higher HbA1c (10.9% vs 8.9%; P < .001), more hypertension (94.2% vs 78·2%; P = .02), longer duration of diabetes (3.4 vs 2.4 years; P = .01), higher distress (9.2 vs 7.3; P = .02), and stress scores (28.7 vs 26.4; P = .03), and elevated inflammatory markers (CRP: 4.9 vs 3.1 mg/L; P = .01, fibrinogen: 3.7 vs 3.3 µmol/L; P = .02). Factors directly associated with ALB in the SEM were hypertension (0.28; P = .001), inflammation (0.41; P < .001), and HbA1c (0.50; P < .001). Psychological health was independently associated with inflammation (-0.20; P < .001) but not directly associated with ALB. CONCLUSIONS: Albuminuria is highly prevalent in Indigenous youth with T2D. This preliminary analysis supports a theoretical framework linking glycemic control, hypertension, and inflammation, potentially mediated by psychological factors with albuminuria. These data support the need for more holistic models of evaluation and care for youth with T2D and multifactorial interventions to prevent complications.

CONTEXTE: L'albuminurie à déclenchement précoce affecte de façon disproportionnelle les jeunes autochtones atteints de diabète de type 2 (T2D). Ces derniers présentent également un risque plus élevé d'insuffisance rénale au début de l'âge adulte. Les approches biologiques traditionnelles n'ont pas été en mesure d'expliquer entièrement la morbidité rénale observée dans cette population. Ainsi, l'étude de cohorte iCARE (improving renal Complications in Adolescents with type 2 diabetes through REsearch) a été conçue en collaboration avec les patients pour évaluer de façon plus globale les facteurs de risque de morbidité rénale. Nous posons l'hypothèse que les résultats rénaux sont influencés à la fois par la santé mentale du patient et des facteurs biologiques, avec médiation par les voies inflammatoires. OBJECTIF: Évaluer le cadre d'analyse iCARE qui examine les liens entre les facteurs biologiques, la santé mentale, l'inflammation et l'albuminurie à l'aide d'une approche de modélisation par équation structurelle (SEM). MÉTHODOLOGIE: Les 187 premiers jeunes autochtones atteints de T2D (âgés de 10 à 25 ans) de la cohorte manitobaine iCARE sont présentés ici pour évaluer notre cadre théorique et analytique. Une SEM a été choisie pour évaluer la pertinence statistique des associations suggérées. Le résultat principal était un rapport urinaire albumine/créatinine non orthostatique d'au moins 2 mg/mmol. Les principaux risques (c.-à-d. les facteurs latents) comprenaient la santé mentale (détresse, stress perçu, bien-être mental et résilience), l'hypertension (suivie sur 24 heures) et les taux de marqueurs inflammatoires (CRP, ESR, fibrinogène). L'hémoglobine A1c (HbA1c) et la période depuis l'apparition du diabète constituaient les covariables. RÉSULTATS: Les sujets retenus (66,8 % de sujets féminins) avaient 15 ans d'âge médian et étaient diabétiques depuis 2,3 ans. Dans cette cohorte, 30,5 % (n = 57) présentaient une albuminurie non orthostatique (confirmée dans 2/3 des échantillons sur une période de six mois) qui s'est avérée persistante dans la majorité des cas (n = 47). Les jeunes souffrant d'albuminurie présentaient des taux plus élevés d'HbA1c (10,9 c. 8,9 %; P < ,001), davantage d'hypertension (94,2 c. 78,2 %; P = ,02), étaient diabétiques depuis plus longtemps (3,4 c. 2,4 ans; P = ,01), vivaient davantage de détresse (9,2 c. 7,3; P = ,02), et présentaient des scores pour le stress (28,7 c. 26,4; P = ,03) et des taux de marqueurs inflammatoires plus élevés (CRP : 4,9 c. 3,1 mg/L; P = ,01, fibrinogène : 3,7 c. 3,3 µmol/L; P = ,02). Avec la SEM, les facteurs directement associés à l'albuminurie étaient l'hypertension (0,28; P = ,001), l'inflammation (0,41; P < ,001) et l'HbA1c (0,50; P < ,001). La santé psychologique a été associée à l'inflammation de manière indépendante (−0,20; P < ,001), mais n'a pas été directement associée à l'albuminurie. CONCLUSION: L'albuminurie est très répandue chez les jeunes autochtones atteints de T2D. Cette analyze préliminaire vient étayer un cadre théorique qui établit un lien entre l'albuminurie et le contrôle de la glycémie, l'hypertension et l'inflammation; lien potentiellement médié par des facteurs psychologiques. Ces données appuient la nécessité d'avoir des modèles plus holistiques d'évaluation et de prise en charge des jeunes atteints de T2D, et des interventions multifactorielles visant à prévenir les complications.

Impact of Vitamin D Supplementation on Gross Motor Development of Healthy Term Infants: A Randomized Dose-Response Trial.

UNLABELLED: In addition to benefits for bone health, vitamin D is implicated in muscle function in children and adults. AIMS: To determine if vitamin D dosage positively correlated with gross motor development at 3 and 6 months of age. We hypothesized that higher doses would be associated with higher scores for gross motor skills. METHODS: A consecutive sample of 55 healthy, term, and breastfed infants from Montreal, Canada were recruited from a randomized trial of vitamin D supplementation between 2009 and 2012. Infants were randomized to 400 International Units (IU) (n = 19), 800 IU (n = 18) or 1,200 IU (n = 18) vitamin D3/day. Motor performance at 3 and 6 months was quantified by the Alberta Infant Motor Scale (AIMS). Plasma vitamin D3 metabolites were measured by tandem mass spectrometry. RESULTS: AIMS scores did not differ at 3 months. However, total AIMS scores and sitting subscores were significantly higher at 6 months in infants receiving 400 IU/day compared to 800 IU/day and 1,200 IU/day groups (p < .05). There were weak negative correlations with length and C-3 epimer of 25(OH)D. CONCLUSIONS: In contrast to our hypothesis, gross motor achievements were significantly higher in infants receiving 400 IU/day vitamin D. Our findings also support longer infants being slightly delayed.

Proposed trial: safety and efficacy of resveratrol for the treatment of non-alcoholic fatty liver disease (NAFLD) and associated insulin resistance in adolescents who are overweight or obese adolescents - rationale and protocol.

Non-alcoholic fatty liver (NAFL) disease (NAFLD) affects 30% of overweight adolescents and increases the risk of type 2 diabetes mellitus (T2D). Resveratrol is a naturally occurring compound with potential to reverse NAFL and its associated insulin resistance in adults. The use of resveratrol to reduce risk for T2D through its effect on NAFL has not been examined to date in youth. This paper provides a literature review and protocol for a 30 day proof of principle trial of resveratrol in a population of adolescents at risk for T2D. This randomized double-blind controlled trial is designed with the primary objective of evaluating a twice daily supplementation of 75 mg of resveratrol for safety and tolerability in overweight and obese adolescent subjects (13 to <18 years of age) with NAFL. Secondary objectives are to determine the effect size of the intervention on hepatic steatosis and whole body insulin sensitivity. Adolescents in the intervention arm (n = 10) will receive oral supplementation of resveratrol 75 mg twice daily (with breakfast and dinner) for a total daily dose of 150 mg for the duration of 30 days. The comparison group (n = 10) will receive a placebo twice daily for 30 days. Both cases and controls will receive a standardized lifestyle intervention program. Subjects in both groups will be followed for an additional 30 days post intervention for total study duration of approximately 60 days. Primary outcome measures include a primary side effect profile determined by participant interview, a side effect profile determined by serum biochemistry and vital signs. Secondary outcome measures include an oral glucose tolerance test, liver and cardiac fat content measured by magnetic resonance spectroscopy, anthropometric measures of overweight/obesity, inflammatory markers, and cardiac function and morphology measured with ultrasonography. Additional outcome measures include serum concentrations of resveratrol, compliance to protocol, physical activity, and nutritional assessment. This study will determine the safety and tolerability of resveratrol in an overweight adolescent population and inform the design of a larger randomized controlled trial.
