RESUMEN
Introduction: Canada promulgated mandatory front-of-pack labelling (FOPL) regulations in 2022, requiring pre-packaged foods meeting and/or exceeding recommended thresholds for nutrients-of-concern (i.e., saturated fat, sodium, sugars) to display a "high-in" nutrition symbol. However, there is limited evidence on how Canadian FOPL (CAN-FOPL) regulations compare to other FOPL systems and dietary guidelines. Therefore, the objectives of the study were to examine the diet quality of Canadians using the CAN-FOPL dietary index system and its alignment with other FOPL systems and dietary guidelines. Methods: Nationally representative dietary data from the 2015 Canadian Community Health Survey-Nutrition survey (n = 13,495) was assigned dietary index scores that underpin CAN-FOPL, Diabetes Canada Clinical Practice (DCCP) Guidelines, Nutri-score, Dietary Approaches to Stop Hypertension (DASH) and Canada's Food Guide (Healthy Eating Food Index-2019 [HEFI-2019]). Diet quality was examined by assessing linear trends of nutrient intakes across quintile groups of CAN-FOPL dietary index scores. The alignment of CAN-FOPL dietary index system compared with other dietary index systems, with HEFI as the reference standard, was examined using Pearson's correlations and к statistics. Results: The mean [95% CI] dietary index scores (range: 0-100) for CAN-FOPL, DCCP, Nutri-score, DASH, and HEFI-2019 were 73.0 [72.8, 73.2], 64.2 [64.0, 64.3], 54.9 [54.7, 55.1], 51.7 [51.4, 51.9], and 54.3 [54.1, 54.6], respectively. Moving from the "least healthy" to the "most healthy" quintile in the CAN-FOPL dietary index system, intakes of protein, fiber, vitamin A, vitamin C, and potassium increased, while intakes of energy, saturated fat, total and free sugars, and sodium decreased. CAN-FOPL showed moderate association with DCCP (r = 0.545, p < 0.001), Nutri-score (r = 0.444, p < 0.001), and HEFI-2019 (r = 0.401, p < 0.001), but poor association with DASH (r = 0.242, p < 0.001). Slight to fair agreement was seen between quintile combinations of CAN-FOPL and all dietary index scores (к = 0.05-0.38). Discussion: Our findings show that CAN-FOPL rates the dietary quality of Canadian adults to be healthier than other systems. The disagreement between CAN-FOPL with other systems suggest a need to provide additional guidance to help Canadians select and consume 'healthier' options among foods that would not display a front-of-pack nutrition symbol.

BACKGROUND & AIMS: Mixed oil intravenous lipid emulsion (MO ILE) that contains 30% soybean oil (SO), 30% medium chain triglycerides, 25% olive oil and 15% fish oil can benefit hospitalized patients receiving parenteral nutrition (PN) but there are very few studies on its long-term use. Our goal was to evaluate the clinical outcomes of adults receiving home PN (HPN) with MO versus those receiving SO ILE over a 2-year period. METHOD: This is a retrospective analysis of data collected prospectively from a cohort of patients recorded in the Canadian HPN Registry over a 2-year period. HPN patients from academic programs across Canada were entered in the Registry according to a validated protocol. For this study, demographic, nutritional, laboratory and clinical data were extracted from January 1st 2015, when MO lipid emulsion became available in Canada, to July 24th 2019. Clinical data for each patient included: number of hospitalizations, number of hospitalizations related to HPN and number of hospitalization days related to HPN, over a year; incidence of line sepsis per 1000 catheter days and mortality. Data are presented as median (1st, 3rd quartile) for continuous variables and frequency (percentage) for categorical variables. Comparisons between groups were performed using two sample t-test or Wilcoxon Rank Sum tests for continuous variables and Chi-square tests or Fisher's exact tests for categorical variables. Univariate and multiple linear regressions were also carried out. Statistical significance is set at a p-value <0.05. RESULTS: A total of 120 patients were included (MO n = 68, SO n = 52). Significant differences at baseline between the two groups were a higher use of Hickman line (62.12% vs 42%, p = 0.038) and more western Canada based hospital care with MO (75% vs 42.31%, p = 0.0002). The MO group had significantly more hospitalizations (p = 0.001), more hospitalizations related to HPN (p = 0.012) and more hospitalization days related to HPN (p = 0.016) per patient per year compared to SO patients. There was no significant difference between groups for line sepsis per 1000 catheter days (MO: 0.05 (0.0, 1.0) vs SO: 0.0 (0.0, 0.22), p = 0.053) or mortality. All other variables, including biochemical variables, were similar between groups. In a multiple regression analysis, the following factors were significantly associated with a greater number of hospitalizations per patient per year: use of MO, high blood glucose from the last recorded value and having died by the end of the study period. CONCLUSION: This 2-year prospective cohort study suggests an increased risk of hospitalization in HPN patients receiving MO lipid emulsion. The long-term effect of using MO lipid emulsion in HPN patients should be further evaluated using a large randomized controlled trial. THE STUDY WAS REGISTERED IN CLINICALTRIALS.GOV: (NCT02299466).

OBJECTIVES: Olive oil (OO)-based intravenous lipid emulsion (IVLE) may have biological advantages for nutrition and inflammation status compared with soybean oil (SO)-based IVLE. We aimed to compare prealbumin levels during infusion of OO- or SO-based IVLE in patients receiving parenteral nutrition in the acute-care setting. METHODS: In this prospective, noninferiority, double blind randomized controlled efficacy trial, patients received either OO-based or SO-based IVLE after providing consent. Biochemical and nutrition parameters were collected at baseline and at 7 to 10 d after initiation of parenteral nutrition. Results are expressed as means (standard deviations). RESULTS: A total of 210 patients completed the study: 102 patients in the SO-based IVLE group and 108 patients in the OO-based IVLE group. Both groups had a significant increase in prealbumin levels from baseline (SO: 0.10 [0.06] versus 0.15 [0.08] g/L; P < 0.0001; OO: 0.11 [0.06] versus 0.16 [0.08] g/L; P < 0.0001), but mean changes between groups were not different (P = 0.53). OO-based IVLE was noninferior to SO-based IVLE in maintaining or increasing serum prealbumin levels, with 20% as the noninferiority margin at follow-up (least square geometric mean ratio [95% CI], 1.10 [0.83,1.47]; P = 0.50). There was a significant improvement in C-reactive protein levels from baseline within each group (SO: 83.24 [69.72] versus 53.4 [59.78] mg/dL; P < 0.0001; OO: 85.13 [68.14] versus 58.75 [60.11] mg/dL; P = 0.004), but mean changes between the groups were not different (P = 0.836). Mortality, length of stay, and infection rates were not different for both groups. CONCLUSIONS: In this study, OO-based IVLE was not inferior to SO-based IVLE in maintaining or increasing the prealbumin level. The improvement of C-reactive protein levels and other clinical outcomes were not different for both groups.

AIMS: To evaluate the impact of the integration of onsite diabetes education teams in primary care on processes of care indicators according to practice guidelines. METHODS: Teams of nurse and dietitian educators delivered individualized self-management education counseling in 11 Ontario primary care sites. Of the 771 adult patients with HbA1c ≥7% who were recruited in a prospective cohort study, 487 patients attended appointments with the education teams, while the remaining 284 patients did not (usual care group). Baseline demographic, clinical information, and patient care processes (diabetes medical visit, HbA1c test, lipid profile, estimated glomerular filtration rate, and albumin-to-creatinine ratio, measuring blood pressure, performing foot exams, provision of flu vaccine, and referral for dilated retinal exam) were collected from patient charts one year before (pre period) and after (post period) the integration began. A multi-level random effects model was used to analyze the effect of group and period on whether the process indicators were met based on practice guidelines. RESULTS: Compared to the usual care group, patients seen by the education teams had significant improvements on indicators for semi-annual medical visit and annual foot exam. No significant improvements were found for other process of care indicators. CONCLUSIONS: Onsite education teams in primary care settings can potentially improve diabetes management as shown in two process of care indicators: medical visits and foot exams. The results support the benefits of having education teams in primary care settings to increase adherence to practice guidelines.

Circumpolar regions, and the nations within which they reside, have recently gained international attention because of shared and pressing public policy issues such as climate change, resource development, endangered wildlife and sovereignty disputes. In a call for national and circumpolar action on shared areas of concern, the Arctic states health ministers recently met and signed a declaration that identified shared priorities for international cooperation. Among the areas for collaboration raised, the declaration highlighted the importance of enhancing intercultural understanding, promoting culturally appropriate health care delivery and strengthening circumpolar collaboration in culturally appropriate health care delivery. This paper responds to the opportunity for further study to fully understand indigenous values and contexts, and presents these as they may apply to a framework that will support international comparisons and systems improvements within circumpolar regions. We explored the value base of indigenous peoples and provide considerations on how these values might interface with national values, health systems values and value bases between indigenous nations particularly in the context of health system policy-making that is inevitably shared between indigenous communities and jurisdictional or federal governments. Through a mixed methods nominal consensus process, nine values were identified and described: humanity, cultural responsiveness, teaching, nourishment, community voice, kinship, respect, holism and empowerment.

Traffic-light labelling has been proposed as a public health intervention to improve the dietary intakes of consumers. OBJECTIVES: to model the potential impact of avoiding foods with red traffic lights on the label on the energy, total fat, saturated fat, sodium, and sugars intakes of Canadian adults. METHODS: Canadian adults aged 19 and older (n = 19,915) who responded to the Canadian Community Health Survey (CCHS), Cycle 2.2. The nutrient levels in foods consumed by Canadians in CCHS were profiled using the United Kingdom's criteria for traffic light labelling. Whenever possible, foods assigned a red traffic light for one or more of the profiled nutrients were replaced with a similar food currently sold in Canada, with nutrient levels not assigned any red traffic lights. Average intakes of calories, total fat, saturated fat, sodium, and sugars under the traffic light scenario were compared with actual intakes of calories and these nutrients (baseline) reported in CCHS. RESULTS: Under the traffic light scenario, Canadian's intake of energy, total fat, saturated fat, and sodium were significantly reduced compared to baseline; sugars intakes were not significantly reduced. Calorie intake was reduced by 5%, total fat 13%, saturated fat 14%, and sodium 6%. CONCLUSION: Governments and policy makers should consider the adoption of traffic light labelling as a population level intervention to improve dietary intakes and chronic disease risk.

BACKGROUND: The causes of stunting are complex but likely include prenatal effects, inadequate postnatal nutrient intake, and recurrent infections. Low-birth-weight (LBW) infants are at high risk of stunting. More than 25% of live births in low- and middle-income countries are at full term with low birth weight (FT-LBW). Evidence on the efficacy of specific interventions to enhance growth in this vulnerable group remains scant. OBJECTIVE: We investigated the independent and combined effects of a directed use of a water-based hand sanitizer (HS) and a mineral- and vitamin-enhanced micronutrient powder (MNP) (22 minerals and vitamins) to prevent infections and improve nutrient intake to reduce stunting in FT-LBW infants. DESIGN: The study was a prospective 2 × 2 factorial, cluster-randomized trial in 467 FT-LBW infants during 2 periods: from 0 to 5 mo postpartum (0-180 d postpartum) and from 6 to 12 mo postpartum (181-360 d postpartum) with the use of 48 clusters. All groups received the same general nutrition, health, and hygiene education (NHHE) at enrollment and throughout the 12 mo. Group assignments initially included the following 2 groups: no HS (control) group or HS from 0 to 5 mo postpartum. These assignments were followed by further divisions into the following 4 groups from 6 to 12 mo postpartum: 1) no HS and no MNP (control), 2) HS only, 3) MNP only, and 4) HS and MNP. RESULTS: When delivered in combination with NHHE, the use of an HS showed no additional benefit in reducing indicators of infection in the first or second half of infancy or the likelihood of stunting at 12 mo postpartum. FT-LBW infants who received the MNP (with or without the HS) were significantly less likely to be stunted at 12 mo than were controls (OR: 0.35; 95% CI: 0.15, 0.84; P = 0.017). CONCLUSIONS: The use of a mineral- and vitamin-enhanced MNP significantly reduced stunting in FT-LBW infants in this high-risk setting. The use of a water-based HS did not have an additive effect. This trial was registered at clinicaltrials.gov as NCT01455636.

This prospective cohort study was conducted in eighteen Canadian hospitals with the aim of examining factors associated with nutritional decline in medical and surgical patients. Nutritional decline was defined based on subjective global assessment (SGA) performed at admission and discharge. Data were collected on demographics, medical information, food intake and patients' satisfaction with nutrition care and meals during hospitalisation; 424 long-stay (≥7 d) patients were included; 38% of them had surgery; 51% were malnourished at admission (SGA B or C); 37% had in-hospital changes in SGA; 19·6% deteriorated (14·6% from SGA A to B/C and 5% from SGA B to C); 17·4% improved (10·6% from SGA B to A, 6·8% from SGA C to B/A); and 63·0 % patients were stable (34·4% were SGA A, 21·3% SGA B, 7·3% SGA C). One SGA C patient had weight loss ≥5%, likely due to fluid loss and was designated as stable. A subset of 364 patients with admission SGA A and B was included in the multiple logistic regression models to determine factors associated with nutritional decline. After controlling for SGA at admission and the presence of a surgical procedure, lower admission BMI, cancer, two or more diagnostic categories, new in-hospital infection, reduced food intake, dissatisfaction with food quality and illness affecting food intake were factors significantly associated with nutritional decline in medical patients. For surgical patients, only male sex was associated with nutritional decline. Factors associated with nutritional decline are different in medical and surgical patients. Identifying these factors may assist nutritional care.

UNLABELLED: In nonalcoholic fatty liver disease, hepatic gene expression and fatty acid (FA) composition have been reported independently, but a comprehensive gene expression profiling in relation to FA composition is lacking. The aim was to assess this relationship. In a cross-sectional study, hepatic gene expression (Illumina Microarray) was first compared among 20 patients with simple steatosis (SS), 19 with nonalcoholic steatohepatitis (NASH), and 24 healthy controls. The FA composition in hepatic total lipids was compared between SS and NASH, and associations between gene expression and FAs were examined. Gene expression differed mainly between healthy controls and patients (SS and NASH), including genes related to unsaturated FA metabolism. Twenty-two genes were differentially expressed between NASH and SS; most of them correlated with disease severity and related more to cancer progression than to lipid metabolism. Biologically active long-chain polyunsaturated FAs (PUFAs; eicosapentaenoic acid + docosahexaenoic acid, arachidonic acid) in hepatic total lipids were lower in NASH than in SS. This may be related to overexpression of FADS1, FADS2, and PNPLA3. The degree and direction of correlations between PUFAs and gene expression were different among SS and NASH, which may suggest that low PUFA content in NASH modulates gene expression in a different way compared with SS or, alternatively, that gene expression influences PUFA content differently depending on disease severity (SS versus NASH). CONCLUSION: Well-defined subjects with either healthy liver, SS, or NASH showed distinct hepatic gene expression profiles including genes involved in unsaturated FA metabolism. In patients with NASH, hepatic PUFAs were lower and associations with gene expression were different compared to SS.

OBJECTIVES: Despite mandatory fortification of milk and margarine, most Canadians have inadequate vitamin D intake and consequently poor vitamin D status, especially in the winter. Increasing vitamin D fortification is one possible strategy to address this inadequacy. The purpose of our study was to examine the modelled effect of increased vitamin D fortification on the prevalence of inadequacy and the percentage of intakes greater than the Tolerable Upper Intake Level (UL) using different fortification scenarios. METHODS: Dietary intakes (24-h recall) from the 2004 Canadian Community Health Survey 2.2 (n=34,381) were used to model increased vitamin D levels in milk and the addition of vitamin D to cheese and yogurt at various levels to meet label claims of an "excellent source" based on the recommended dietary intakes. The Software for Intake Distribution Evaluation was used to estimate the prevalence of inadequacy and intakes >UL. RESULTS: Fortification of milk, yogurt and cheese at 6.75 µg (270 IU)/serving led to more than doubling of vitamin D intakes across all sex/age groups and a drop in the prevalence of dietary inadequacy from >80% to <50% in all groups. Furthermore, no intakes approached the UL under any fortification scenario in any sex/age group. CONCLUSION: There is a pressing need to improve vitamin D status among Canadians. Increasing vitamin D fortification of dairy products, consistent with their positioning in Canada's Food Guide, can lead to increased intake without a risk of excess. This is a population-wide public health strategy that should be given consideration in Canada.

BACKGROUND: There is evidence to suggest that delivery of diabetes self-management support by diabetes educators in primary care may improve patient care processes and patient clinical outcomes; however, the evaluation of such a model in primary care is nonexistent in Canada. This article describes the design for the evaluation of the implementation of Mobile Diabetes Education Teams (MDETs) in primary care settings in Canada. METHODS/DESIGN: This study will use a non-blinded, cluster-randomized controlled trial stepped wedge design to evaluate the Mobile Diabetes Education Teams' intervention in improving patient clinical and care process outcomes. A total of 1,200 patient charts at participating primary care sites will be reviewed for data extraction. Eligible patients will be those aged ≥18, who have type 2 diabetes and a hemoglobin A1c (HbA1c) of ≥8%. Clusters (that is, primary care sites) will be randomized to the intervention and control group using a block randomization procedure within practice size as the blocking factor. A stepped wedge design will be used to sequentially roll out the intervention so that all clusters eventually receive the intervention. The time at which each cluster begins the intervention is randomized to one of the four roll out periods (0, 6, 12, and 18 months). Clusters that are randomized into the intervention later will act as the control for those receiving the intervention earlier. The primary outcome measure will be the difference in the proportion of patients who achieve the recommended HbA1c target of ≤7% between intervention and control groups. Qualitative work (in-depth interviews with primary care physicians, MDET educators and patients; and MDET educators' field notes and debriefing sessions) will be undertaken to assess the implementation process and effectiveness of the MDET intervention. TRIAL REGISTRATION: ClinicalTrials.gov NCT01553266.

OBJECTIVE: To explore physicians' knowledge of and attitudes toward hyperbaric oxygen therapy (HBOT) in order to better understand current diabetic foot ulcer management practices and to determine potential barriers to HBOT use. DESIGN: A 24-item questionnaire. SETTING: Primary Care Today conference in Toronto, Ont, in May of 2006. PARTICIPANTS: Physician attendees, 313 of whom completed the survey. MAIN OUTCOME MEASURES: Self-reported knowledge of and attitudes toward HBOT. RESULTS: Less than 10% of respondents had a good knowledge of HBOT, but 57% had a good attitude toward HBOT. Knowledge of and attitude toward HBOT were positively correlated (P < .0001). Good knowledge of HBOT was associated with sex (P = .0334), age younger than 40 years (P = .0803), years in medical practice (P = .0646), patient requests for HBOT referrals (P = .0127), and having previously referred patients for HBOT (P < .001). Twenty years or more in medical practice (P = .0593) and receiving patient requests for HBOT (P = .0394) were multivariate predictors of having good knowledge of HBOT. Good attitude toward HBOT was associated with age younger than 40 years (P = .0613) and having previously referred patients for HBOT (P = .0013). Multivariate analysis showed that male physicians (P = .0026) received more patient requests for HBOT (P < .0001), had good knowledge (P = .0129) and a good attitude (P = .0488), and were more likely to refer patients for HBOT. CONCLUSION: Primary care physicians have underdeveloped knowledge of HBOT, but their generally positive attitudes toward its use suggest that they might be receptive to educational interventions. Educating both physicians and patients about HBOT, specifically its cost-effectiveness, might encourage future use.
