ABSTRACT

OBJECTIVE: Electronic scooter (eScooter) popularity has soared, despite public concerns around injury risk. We aimed to explore the burden of injury from eScooters presenting to Tasmania's major trauma centre during the first 6 months of the Hobart eScooter trial. METHODS: We screened all ED presentations and interhospital transfers from 11 December 2021 to 26 June 2022 to identify eScooter-associated injury. All injuries were coded using the Abbreviated Injury Scale and an Injury Severity Score (ISS) was computed for each presentation. Data were entered into the Tasmanian Trauma Registry and then exported into standard statistical software for descriptive analysis. RESULTS: There were 135 eScooter presentations to the ED and 31 were admitted. Patients were mostly young (median age 27 years) with an even sex distribution. Injuries were mostly minor (median ISS of 2) with injuries to soft tissues and the head and neck predominating. Approximately, one-third required operative interventions, but none required intensive care. Injured patients were less likely to have been wearing protective gear (36% helmet wearing) and alcohol intoxication was common (41% overall, 71% admitted patients). CONCLUSION: Overall, our 6-month prospective dataset shows that the Hobart eScooter trial has been associated with few major injuries.

ABSTRACT

Stage III-IV non-small cell lung cancer (NSCLC) is a devastating disease characterized by a poor prognosis. NSCLC tumors carry genetic mutations, which can lead to the expression of altered protein sequences. Peptides originating from mutated proteins and bound to MHC molecules on the tumor cell surface are referred to as neoantigens, as they are tumor-specific and not expressed in normal cells. Due to their tumor specificity, neoantigens have a strong potential to induce an anti-tumor immune response and have been investigated for development of personalized therapeutic cancer vaccines. The current study describes the development of a clinical grade neoantigen vaccine formulation (FRAME-001) intended as immunotherapy in advanced NSCLC in combination with the immune checkpoint inhibitor pembrolizumab. The detection of aberrant tumor-specific transcripts as well as an algorithm to select immunogenic neoantigen peptides are described. Subsequently, selected neoantigen peptides were synthesized with a high throughput synthesis platform and aseptically formulated under good manufacturing practice (GMP) conditions into four aqueous peptides mixtures that each contained six neoantigen peptides. A validated stability-indicating analytical method was developed in which we considered the personalized nature of the formulation. An extensive stability study performed either at -25 °C or -80 °C showed that the formulation was stable for up to 32 weeks. The formulation was mixed with the vaccine adjuvant Montanide ISA 51 VG, which yielded the final vaccine emulsion. The stability of the vaccine emulsion was demonstrated using microscopic examination, differential light scattering, and the water-drop test. The presented data show that FRAME-001 is a feasible personalized vaccine formulation for the treatment of stage III-IV NSCLC. The presented data may give guidance in the development of novel personalized therapeutic vaccines since this formulation strategy could be used for any cancer indication.

ABSTRACT

Country-specific food composition data are needed for gluten-free (GF) food products to assess nutritional adequacy and diet quality. This research aimed to develop a comprehensive GF food composition database for key GF foods consumed in Canada. Average nutrient data from 167 products were estimated from Nutrition Fact Panel labels and the commercial ingredient list, using an iterative and systematic approach. The database reports mean values for energy and 29 nutrients per 100 g for 33 GF commercial grain-based foods. Nutrient values were evaluated with Health Canada's nutrient content claims per standard reference serving. On average, GF products were, at minimum, a source of thiamin (73%), riboflavin (70%), niacin (58%), iron (58%), fibre (55%), magnesium (48%), folate (36%), zinc (19%), and calcium (15%). Most GF products were low in saturated fat (85%) and cholesterol (64%) but only 15% were low in total fat and 6% were free of sugar. Micronutrient enrichment and the use of nutrient-dense whole grain flours, legume flours, oil seed husks, and functional fibre ingredients varied within and between categories and brands but appeared to contribute to nutrient content. This database provides a new tool to enhance GF diet assessment in individuals or populations in Canada.

ABSTRACT

To determine the food sources of energy and 13 core nutrients, 89 diet recalls were analyzed from an explanatory mixed-methods pilot study with adults following a gluten-free diet (GFD) for any reason. Nonconsecutive dietary recalls were collected through a web-based, Automated Self-Administered 24-Hour (ASA24®-Canada-2016) Tool. Mean nutrient intakes were compared with Dietary Reference Intakes. Food items (excluding supplements) were extracted and categorized according to the Bureau of Nutritional Sciences Food Group Codes. Percentages of total dietary intakes from food sources were ranked. Grain products were the highest ranked contributor of energy (21.4%), carbohydrate (30.3%), fibre (29.1%), and iron (35.3%). Breakfast cereals, hot cereals, yeast breads, and mixed grain dishes (mainly rice or pasta-based) were the most important nutrient contributors for grains, despite most (64.3%) commercial cereals and breads being unenriched. Legumes and seeds were not frequently consumed. Nutrient density in the GFD could be improved with more emphasis on gluten-free (GF) whole grains, legumes, seeds, and enriched breads and cereals. More research is needed on the nutrient composition of GF foods to identify food sources of folate, other B vitamins, zinc and magnesium-nutrients of concern for those requiring a GFD.

ABSTRACT

BACKGROUND: The gluten-free diet (GFD) involves the elimination of wheat and related grains. Wheat is a key fortification vehicle for nutrients such as iron and B vitamins. While there is growing evidence of low nutrients intake and poor diet quality amongst people following long-term GFD, few studies have used a dietary pattern approach to analyse top food sources of nutrients in today's complex food environment. Thus, the purpose of this study was to identify food sources of energy and nutrients from previously collected diet records of adults following a GFD. METHODS: Three, 3-day food records were collected from 35 participants in a lifestyle intervention study (n = 240 records). All food items were categorised according to the Bureau of Nutritional Sciences Food Group Codes. Percentages of total dietary intakes from food groups were ranked. RESULTS: Mean intakes of dietary fibre, calcium and iron (females) were lower than recommended, with half the sample consuming below the recommended proportion of energy as carbohydrate. Meat, poultry and fish were the top source of energy (19.5%) in the diet. Gluten-free (GF) grain products were the top source of carbohydrate, fibre and iron and second greatest source of energy. Amongst grains, breakfast/hot cereals, yeast breads, and mixed grain dishes were the greatest nutrient contributors, despite most commercial cereals and breads (65%) being unenriched. Legumes were not frequently consumed. CONCLUSIONS: GF grains were the top food source of carbohydrate, fibre and iron, despite few brands being enriched or fortified. It is a challenge to assess and monitor nutrient intakes on GFD due to the lack of nutrient composition data for B vitamins and minerals (other than iron). Dietary planning guidance for the appropriate replacement of nutrients provided by wheat is warranted.

ABSTRACT

Concerns about the nutritional and sensory qualities of gluten-free (GF) products has generated interest in the evaluation of novel gluten-free ingredients. Folate content is of particular interest due to limited sources of enriched folic acid in a GF diet as well as lack of nutrient composition data in novel flours. The aim of this study was to determine the total folate content and chemical composition of GF flours commercially available in Canada. A tri-enzyme method was used to extract folate from the flour samples, and a microbiological assay was used to measure the total folate contents. The chemical compositions of the GF flours were determined according to standard Association of Official Agricultural Chemists (AOAC) International methods. Compared to all-purpose flour, 265 ± 6.9 µg/100 (dry-weight basis), chickpea flour registered the highest folate content 451 ± 10.8 µg/100 (dry-weight basis) followed by quinoa flour, 174 ± 12.4 µg/ 100 g folate (dry-weight basis). Fonio, had a total starch content of ~77% but was not a source of folate. Flaxseed, chickpea, chia and coconut flours had the highest reported protein contents (mean value: 21.3 ± 1.3%) whereas flaxseed (~42%), and chia (~35%), had the highest lipid content. These findings may inform the selection of gluten-replacement flours with acceptable nutritional properties.

ABSTRACT

OBJECTIVE: Demand for global health (GH) training and experiences among emergency medicine trainees is unknown. The primary objective of the Trainee Interest in Global Health Training (TIGHT) study was to quantify the number of trainees interested in completing a rotation in a resource-limited environment within a low- or middle-income country during their specialty training. METHODS: A cross-sectional study of trainees in seven specialty training programmes was conducted between August and October 2018. Data were collected using a voluntary, anonymous, self-reporting, web-based survey. This study describes the results of a planned sub-group analysis of ACEM trainees. RESULTS: There were 203 respondents among 2525 ACEM trainees. Although only a small number (36/198, 18.2%) had undertaken a GH experience as a specialty trainee, 85.6% (167/195) were keen to do so. The vast majority of respondents (179/194, 87.1%) were interested or very interested in having their GH experience accredited for training, but 68.9% (133/193) reported that accessing a suitable placement was a barrier. More than 79% (147/186) expressed interest in undertaking an integrated GH training or fellowship programme as an adjunct to specialty training. CONCLUSIONS: Notwithstanding the limitations of a self-reporting survey with a sub-optimal response rate, there is significant demand for GH training and experiences among ACEM trainees. These findings should inform the development of safe and effective global emergency care training pathways, underpinned by mutually beneficial, international partnerships with educational and development objectives.

ABSTRACT

The strict nature of a gluten-free diet (GFD) poses a challenge for patient adherence and for clinicians to provide comprehensive client-centered care. Evidence on the relationship between nutrition knowledge, food skills, dietary management, and adherence can guide healthcare professionals counseling patients following this diet. In this explanatory pilot study, a province-wide survey (phase I) with 68 community-dwelling Nova Scotians following a GFD was conducted to investigate relationships between personal, social, and health care factors and dietary adherence using a mixed-methods approach. A sub-sample of 19 survey respondents were interviewed (phase II) to explore contextual experiences related to GFD knowledge, food skills, dietary management, and adherence using a food literacy lens. Here, we report findings from phase I, in which 37 participants with self-reported celiac disease (CD) and 31 participants reporting non-celiac reasons for wheat restriction (NCWR) completed a detailed 41-item online questionnaire. Self-reported data combined for both CD and NCWR respondents showed 76% perceived their health status as good to excellent. Most (62%) reported not receiving GFD advice from a health professional. Respondents with higher frequency of intentional consumption of gluten were more likely to have fewer correct answers to a food label quiz (ρ = -0.44; P = .0002). Most participants (75%) made at least one error in identifying gluten-free and gluten-containing foods, which may lead to unintentional gluten consumption and/or unnecessarily restricting safe foods. Findings from this exploratory study suggest patients may lack adequate referrals and support within the health care system and the community, adding to individual challenges of GFD adherence.

ABSTRACT

BACKGROUND: Caribou (Rangifer tarandus) is the top dietary source of iron and several micronutrients necessary for red blood cell production (erythropoiesis) in the contemporary diet of Inuit adults across Canada. Many caribou populations across the circumpolar north, however, have experienced dramatic declines in recent decades. Restricted access to caribou may negatively impact the nutrition and health of Inuit communities. METHODS: We used data from the Inuit Health Survey, a cross-sectional survey of 2550 Inuit adults in thirty-six communities across northern Canada (conducted in 2007-2008) to examine the relationship between caribou consumption, hemoglobin (Hb), and blood biomarkers of nutrient intake and contaminant exposure. Multivariable linear regression was used to investigate the potential public health impact of a theoretical restriction in caribou consumption, by estimating the response of Hb concentrations (and the attendant change in anemia prevalence), to theoretical changes in caribou consumption (with and without substitution of caribou with other country food meat). RESULTS: Mean (95% CI) daily caribou meat consumption differed by an order of magnitude 4.3 (3.9-4.7), 51.1 (48.5-53.8), and 236.7 (224.7-248.7) grams/day between tertiles of caribou consumption. Mean (95% CI) hemoglobin levels increased from 129.1 (128.1-130.2) g/L to 132.5 (131.3-133.7) g/L between the highest and lowest tertiles of caribou consumption. In multivariable regression analyses, average daily caribou meat consumption was positively associated (P< 0.001) with hemoglobin levels. This relationship translated into approximately 4 g/L hemoglobin increase in participants in the third tertile of caribou consumption. The overall prevalence of anemia observed in the study population was 26.5% (24.5 - 28.3%) and a modelled restriction in caribou consumption (i.e. caribou = 0) increased the overall prevalence of anemia by approximately 6%. The maximum negative effect of caribou restrictions was related to a complete restriction on caribou consumption, coupled with the substitution of caribou with other country food meat (35.4% prevalence). CONCLUSIONS: Given the importance of caribou to Inuit culture, health and wellbeing, and the high price of healthful market foods in remote northern communities, strategies to promote the sustainable harvest of country foods are urgently required to ensure the health and nutrition security of the Inuit, in the context of rapidly changing Arctic environments and ecosystems.

ABSTRACT

BACKGROUND: A strict gluten-free (GF) diet is required for the management of celiac disease (CD). The nutritional adequacy of this diet has been questioned due to the elimination of wheat, an important vehicle for micronutrient fortification and source of fibre. While novel and/or reformulated packaged GF products have rapidly entered the marketplace, providing alternatives to wheat-based staples, it is unknown whether these new products are nutritionally comparable. METHODS: From a database of 3,851 foods collected across 21 grocery stores in Eastern Canada, we compared the nutrient content of 398 unique GF items with 445 gluten-containing (GC) equivalents. Wilcoxon rank tests were conducted on listed nutrient content (g, mg, µg) per 100 g of product and the nutrient contribution of iron, folate and fibre were evaluated using Health Canada's nutrient claim regulations. RESULTS: GF staples (cereals, breads, flours, pastas) contained 1.3 times more fat and less iron (by 55%), folate (by 44%) and protein (by 36%), than GC counterparts (P < 0.0001). On average, GF pastas had only 37% of the fibre in GC pastas (P < 0.0001). Notably, GF and GC flours were equivalent in nutrient content. Despite GF and GC flours having similar nutritional content, the vast majority of the processed GF foods fell short in key nutrients. DISCUSSION: Packaged GF foods in Canada are generally less nutritious than their GC counterparts, suggesting that GF diets should not be promoted to those who do not require it. The use of nutrient-dense GF flours in homemade foods may improve nutrient intakes on the GF diet.

ABSTRACT

BACKGROUND: Idiopathic capillary leak syndrome (Clarkson's Disease) is a rare angiopathy with a heterogenous phenotype that may present as distributive shock refractory to resuscitative management. OBJECTIVE: We report a case of idiopathic systemic capillary leak syndrome presenting as septic shock. METHODS: Structured case report and review of the literature. RESULTS: A 27-year old man admitted to our institution with coryzal symptoms rapidly deteriorated with presumed sepsis, leading to intensive care unit admission. Following further deterioration, Idiopathic systemic capillary leak syndrome was considered and intravenous immunoglobulin administered, resulting in rapid improvement in the patient's clinical status. CONCLUSIONS: Idiopathic systemic capillary leak syndrome is a rare and potentially life-threatening angiopathy that may present as, and should be considered in, refractory distributive shock. Administration of intravenous immunglobulin resulted in rapid recovery in this patient, and has been associated with positive outcomes in previous cases.

ABSTRACT

PURPOSE: University students may be at risk for food insecurity (FI) due to low income coupled with rising tuition, housing, and food costs. This study aimed to determine the prevalence of FI and potential correlates among students at a small, rural Canadian university. METHODS: Health Canada's 10-item household food security survey module (HFSSM) was adapted to assess food security status within the postsecondary student population. An additional 11 items measured food access and demographics. The validated, web-based survey was distributed by email and completed by 218 students (15.6% response rate). Participants were classified as food secure, moderately food insecure, or severely food insecure using the HFSSM Adult scale. RESULTS: An overall FI rate of 37.2% was observed. This included 25.7% moderately food insecure and 11.5% severely food insecure. Students in higher years of study and who lived off campus had higher rates of FI. CONCLUSIONS: FI appears to be a significant concern for university students and has potential health and academic implications. Further research is needed to clarify the determinants and extent of FI for postsecondary students and to develop strategies to mitigate the prevalence and effects of food insecurity in these young adults.

ABSTRACT

We investigated the price difference between gluten-free (GF) and gluten-containing (GC) foods available in rural Maritime stores. GF foods and comparable GC items were sampled through random visits to 21 grocery stores in nonurban areas of Nova Scotia, New Brunswick, and Prince Edward Island, Canada. Wilcoxon rank tests were conducted on price per 100 g of product, and on the price relative to iron content; 2226 GF foods (27.2% staple items, defined as breads, cereals, flours, and pastas) and 1625 GC foods were sampled, with an average ± SD of 66 ± 2.7 GF items per store in rural areas and 331 ± 12 in towns. The median price of GF items ($1.76/100 g) was more expensive than GC counterparts ($1.05/100 g) and iron density was approximately 50% less. GF staple foods were priced 5% higher in rural stores than in town stores. Although the variety of GF products available to consumers has improved, higher cost and lower nutrient density remain issues in nonurban Maritime regions. Dietitians working in nonurban areas should consider the relative high price, difficult access, and low iron density of key GF items, and work together with clients to find alternatives and enhance their food literacy.

ABSTRACT

OBJECTIVE: To identify correlates of hemoglobin (Hb) and anaemia unexplained by iron deficiency (UA) in Canadian Inuit adults. METHODS: A cross-sectional survey assessed diet, demographic information, anthropometry, fasting Hb, ferritin, soluble transferrin receptor (on a subset), high-sensitivity C-reactive protein (hs-CRP) in serum, red blood cell (RBC) fatty acid composition, blood lead, and antibodies to Helicobacter pylori in non-pregnant, Inuit adults (n = 2550), ≥18 years of age from randomly selected households in 36 Inuit communities in Inuvialuit Settlement Region, Nunavut Territory and Nunatsiavut of Northern Labrador, Canada. RESULTS: Hb concentrations were lower and UA prevalence higher in Inuit men after 50 years of age. Rate of anaemia was constant among Inuit women but changed from primarily iron deficiency anaemia pre-menopause, to primarily UA in post-menopause. Low education levels and hs-CRP were associated with increased risk of UA. For Inuit men, % RBC eicosapentaenoic acid (EPA) and elevated blood lead were also associated with increased risk of UA. Frequency of traditional food intake was positively associated with Hb. CONCLUSION: Age patterns and regional variation of anaemia suggest that ethnicity-related physiological differences cannot explain anaemia prevalence for Inuit. High RBC EPA status, inflammation and infections, and lower education levels may contribute to the prevalence of anaemia in this population, which is not related to iron status. Thus, traditional lifestyle may protect Inuit from nutritional anaemia but contribute to lower Hb through environmental exposures. The clinical significance of UA for older Inuit adults requires further investigation, as the prevalence represents a moderate public health problem.
