ABSTRACT

INTRODUCTION: The purpose of this study was to investigate the relationship between ultra-processed food (UPF) consumption and (i) symptomatic disease and (ii) intestinal inflammation among adults with inflammatory bowel disease (IBD). METHODS: We identified participants (Crohn's disease [CD] and ulcerative colitis [UC]) from the Manitoba Living with IBD study. Active disease was defined using the IBD Symptom Inventory (score >14 for CD; >13 for UC); fecal calprotectin was measured for intestinal inflammation (>250 µg/g). Diet data were collected using the Harvard Food Frequency Questionnaire. UPF consumption was determined by the NOVA classification system. Percentage of energy consumption from UPFs was calculated and divided into 3 tertiles (T1 = low; T3 = high). Multiple linear regression analysis was used for active disease and inflammation predicted by UPF consumption. RESULTS: Among 135 participants (65% with CD), mean number of episodes of active disease (14.2 vs 6.21) and active inflammation (1.6 vs 0.6) was significantly higher among participants with UC in T3 compared with T1 of UPF consumption ( P < 0.05). When adjusting for age, sex, disease type, and duration, number of episodes of active disease was lower in T1 compared with T3 (ß = -7.11, P = 0.02); similarly, number of episodes of intestinal inflammation was lower in T1 (ß = -0.95, P = 0.03). No significant differences were observed among participants with CD. DISCUSSION: UPF consumption may be a predictor of active symptomatic disease and inflammation among participants with UC. Reducing UPF consumption is a dietary strategy that can be suggested for minimizing symptoms and inflammation among people living with IBD.

ABSTRACT

BACKGROUND: Among women of reproductive age with inflammatory bowel disease (IBD), we aimed to assess the relationship of hormonal contraceptives (HCs) with IBD-related symptoms, and intestinal inflammation. METHODS: A nested cohort of women in the longitudinal Manitoba Living with IBD Study, ages 18 to 49, were followed for 1 year, with bi-weekly online surveys. This included a validated measure of disease activity; IBD Symptom Inventory (IBDSI), and stool samples obtained at 3 time-points for assessment of fecal calprotectin (FCAL). Use of HC included oral and vaginal intrauterine devices. Logistic regression analysis was used to assess the association between HC and IBD-related symptoms (IBDSI>14 for Crohn disease, >13 for ulcerative colitis), or inflammation (FCAL>250 ug/g) at any measurement point in the study. RESULTS: Of 71 women, 17 (24%) reported taking HC in the 1 year period. Adjusting for age, disease type, disease duration, and smoking status, the odds of having increased IBD-related symptoms (IBDSI) during the year were lower for women using HC compared with women not using HC [adjusted odds ratio 0.16, 95% CI, 0.02-0.90]. Conversely, women using HC were more likely to have inflammation during the year [adjusted odds ratio 5.7, 95% CI, 1.23-43.6]. CONCLUSIONS: HC use among women with IBD was associated with a lower likelihood of IBD-related symptoms but a higher likelihood of experiencing intestinal inflammation (FCAL>250 ug/g) over 1 year. Further work is needed to examine this dichotomous result, potentially examining aspects such as duration of HC use, and the types of HC.

ABSTRACT

BACKGROUND: In this matched case-control longitudinal study among people living with inflammatory bowel disease (IBD), we investigated beliefs about what triggers a flare. METHODS: Adults with confirmed IBD and active disease within 2 years were enrolled in the Manitoba Living with IBD Study and followed biweekly with online surveys for 1 year. The 7-point IBD Symptom Change Indicator was used for participant identification of a flare. Flare cases were matched to non-flare controls by sex and disease type. Members of each matched pair completed supplementary information on diet changes and psychological functioning in the previous 2 weeks and provided stool samples to assess fecal calprotectin (FCAL). RESULTS: Of 128 enrolled participants, 95 matched flare/non-flare pairs were created. Those reporting a flare were more likely to have elevated FCAL (51% vs 34% among non-flares, P = 0.043). Although 61% of study participants believed at baseline that a food may trigger flares, and 25% of those in a flare believed that a food may have triggered their current flare, there was no difference in consumption of assessed foods between flares and non-flares in the previous 2 weeks. Patients with flares were more likely to be having difficulties in emotional state than controls (40% vs 18%, P = 0.001) and more likely to be stressed or worried (64% vs 33%, P = 0.001). CONCLUSION: Although a majority of individuals with IBD believe that specific foods trigger their disease flares, this was not supported by the current findings. Recent psychological functioning was associated with self-reported IBD flare.

ABSTRACT

BACKGROUND: Flare is a poorly defined term used by patients and clinicians to indicate inflammatory bowel disease (IBD) status. This study aimed to evaluate the validity of a single-item 7-point flare indicator relative to other measures of disease flare. METHODS: The longitudinal Manitoba Living with IBD Study followed persons with IBD for 1 year; they completed biweekly online surveys and provided 3 stool samples. Disease flare on a single-item flare indicator with 7 possible responses developed for the study was defined by report of symptoms as "moderately" or "much" worse. The flare indicator was evaluated against 5 measures of disease activity: fecal calprotectin score (FCAL), a 2-point disease status indicator, a 4-point flare certainty indicator, the IBD Symptom Index short form (SIBDSI), and the short form IBD Questionnaire (SIBDQ). Participants in a flare, based on the 7-point measure, were matched to a nonflaring participant, and a stool sample was collected. RESULTS: Of the 155 IBD participants, almost half (n = 74) experienced a flare. Of those who flared, 97.0% endorsed active IBD on the 2-point indicator (controls 42.5%; P < .001); 91.9% endorsed active IBD on the 4-point certainty indicator (controls 32.9%; P < .001); 90.5% endorsed active disease on the SIBDSI (controls 34.2%; P < .001); and 48.5% had an elevated FCAL (controls 34.3%; P < .05). The mean SIBDQ was lower for the flare group compared with controls (43.9 [SD 11.1] vs 58.3 [SD 8.5]; P < .001), indicating worse disease. CONCLUSIONS: The 7-point flare indicator robustly identified symptomatic flares. This patient self-report indicator reflected meaningful changes in more complex clinical indices and had only weak concordance with the presence of inflammation.

ABSTRACT

BACKGROUND: We aimed to examine whether an association exists between diet quality, based on the Prospective Urban Rural Epidemiology (PURE) Healthy Diet Score (HDS), and active inflammatory bowel disease (IBD). METHODS: Participants were drawn from the Manitoba Living With IBD Study cohort. The Harvard Food Frequency Questionnaire (FFQ) was used to calculate the HDS at two time points: baseline and 1-year follow-up. Using generalized estimating equations (GEE) logistic regression, we assessed the association between the HDS and (1) the IBD Symptom Inventory (IBDSI); (2) intestinal inflammation, measured by fecal calprotectin (FCAL); and (3) self-reported IBD flares. RESULTS: There were 294 completed FFQs among 153 people. Of these, 100% had completed data about an IBD flare, 98% had FCAL measurements, and 96% had completed IBDSI scores. On a HDS scoring method of 0-8, the odds of FCAL >250 mcg/g were lower for participants with a HDS of 4 vs 0-3 (adjusted odds ratio [OR], 0.38; 95% CI, 0.19-0.77). When applying a second HDS scoring method (8-40), the odds of having an IBD flare were 3.6 times greater with a HDS between 21 and 24 compared with an HDS ≤20 (adjusted OR, 3.63; 95% CI, 1.03-12.78). CONCLUSIONS: We found that active inflammation was less likely among those with a moderate HDS , whereas symptomatic IBD flares were more likely. People may choose to consume a moderate amount of healthy foods such as fruits and vegetables, even knowing that those foods may cause a symptomatic flare.

ABSTRACT

Data has indicated that gluten-free (GF) foods are more expensive and have lower nutritional value than their gluten-containing (GC) counterparts. The aim of the present study was to compare the cost and nutrient content between GF and GC staple foods and determine whether the number and price of GF staple foods differed based on type of store or location within Winnipeg, Canada. Twelve grocery stores (2 chain stores/quadrant;1 local store/quadrant) in the four quadrants (northwest, northeast, southwest, southeast) of Winnipeg were visited to identify GF staple products (bread, flour, cereal, pasta) along with a GC comparator. A total of 819 GF products along with GC comparators were identified. The median cost of GF products ($1.50/100 g) was 131 % greater than that of GC ($0.65/100 g) (p < 0.0001). The greatest difference in cost was between GF and GC flour, with the least difference occurring between GF and GC cereal. GF products were 58, 36 and 100 % lower in iron, protein and saturated fat (p < 0.0001) than their GC comparators, respectively. The number of GF staple products was 370 % higher (p < 0.007) at chain stores than at local stores, whereas store location did not significantly affect the number of GF products available. The greatest difference in number of different GF foods based on store type was for cereals, with the least being for flours. These results confirm that GF staple foods are more expensive and have lower nutritional value (mainly due to lower iron and protein content) compared to GC foods.

ABSTRACT

OBJECTIVE: The microbiome contributes to the pathogenesis of inflammatory bowel disease (IBD) but the relative contribution of different lifestyle and environmental factors to the compositional variability of the gut microbiota is unclear. DESIGN: Here, we rank the size effect of disease activity, medications, diet and geographic location of the faecal microbiota composition (16S rRNA gene sequencing) in patients with Crohn's disease (CD; n=303), ulcerative colitis (UC; n = 228) and controls (n=161), followed longitudinally (at three time points with 16 weeks intervals). RESULTS: Reduced microbiota diversity but increased variability was confirmed in CD and UC compared with controls. Significant compositional differences between diseases, particularly CD, and controls were evident. Longitudinal analyses revealed reduced temporal microbiota stability in IBD, particularly in patients with changes in disease activity. Machine learning separated disease from controls, and active from inactive disease, when consecutive time points were modelled. Geographic location accounted for most of the microbiota variance, second to the presence or absence of CD, followed by history of surgical resection, alcohol consumption and UC diagnosis, medications and diet with most (90.3%) of the compositional variance stochastic or unexplained. CONCLUSION: The popular concept of precision medicine and rational design of any therapeutic manipulation of the microbiota will have to contend not only with the heterogeneity of the host response, but also with widely differing lifestyles and with much variance still unaccounted for.

ABSTRACT

BACKGROUND: We aimed to investigate (1) the stability of inflammatory aspects of diet over 1 year among persons with inflammatory bowel disease (IBD) and (2) the impact of change in diet on changes in inflammation and IBD symptoms over 1 year. METHODS: Participants were recruited to the Manitoba Living with IBD Study and completed the Harvard Food Frequency Questionnaire (FFQ). The Dietary Inflammatory Index (DII) and the Empirical Dietary Inflammatory Index (EDII) were used to calculate the inflammatory potential of the diet. Inflammation was measured by fecal calprotectin (≥250 µg/g). Symptoms were measured by the IBD Symptom Inventory (IBDSI). All measures were obtained at baseline and 1 year. Dietary Inflammatory Index and Empirical Dietary Inflammatory Index scores >0 and <0 reflect pro- and anti-inflammatory diet, respectively. Variance components analyses were used to describe diet stability. Associations between changes in diet and changes in active inflammation and symptoms were assessed using ordinal logistic regression and multilevel linear regression modeling. RESULTS: One hundred thirty-five participants (66% CD) were included. Approximately one third of the variance in EDII (36%) and DII (33%) scores was explained by changes in diet over time. Each unit increase in the change in EDII (baseline to follow-up) was associated with a greater odds of FCAL, indicating active inflammation (>250 µg/g; odds ratio, 3.1; 95% confidence interval [CI], 1.02-9.93; P = 0.04) and with a rise in IBDSI of 6.7 (95% CI, 1.0-12.4; P = 0.022; theoretical IBDSI range, 0-81). There was no association between changes in DII and changes in FCAL or IBDSI. CONCLUSION: The EDII, but not the DII, may have utility to identify the inflammatory potential of diet. This inflammatory potential can contribute to inflammation and/or disease symptoms in persons with IBD.

ABSTRACT

PURPOSE: Many patients with cancer are interested in complementary therapies, including strategies such as reduced carbohydrate diets. Guidelines regarding the use of these diets during cancer treatment are lacking; therefore, we aimed to explore the perceptions and practices of medical oncologists in Canada regarding low-sugar and ketogenic diets. METHOD: A cross-sectional, online multiple-choice survey was distributed to 206 Canadian medical oncologists. Questions explored frequency of patient interactions, oncologist perceptions of efficacy, advice given to patients, and concerns about side effects related to reduced carbohydrate diets. RESULTS: Responses were received from 57 medical oncologists in seven of thirteen provinces and territories, with an overall response rate of 28%. Forty-nine percent of respondents were asked at least weekly about a low-sugar diet, and 9% about the ketogenic diet. Eighty-five percent supported the use of a low-added sugar diet in patients with diabetes or hyperglycemia, while conversely 87% did not support the use of a ketogenic diet for any of their patients undergoing active cancer treatment. Respondents felt either that a ketogenic diet was not effective (31%) or that the effect on cancer outcomes was unknown (69%). Ninety-six percent of respondents had concerns about a ketogenic diet for patients receiving active cancer treatment. CONCLUSION: The role of reduced carbohydrate diets during cancer treatment is topical. Canadian oncologists are particularly reluctant to support a ketogenic diet for patients on active cancer treatment, with concerns about side effects and unknown efficacy. There may be a role for continuing medical education and institutional guidelines to inform these discussions with patients.

ABSTRACT

PURPOSE: The objectives of this study were (i) to describe ethnicity, tuition funding sources, and living arrangements during degree among Registered Dietitian (RD) and non-RD alumni of the University of Manitoba's undergraduate nutrition program and (ii) to describe barriers to obtaining an internship among those who did not become an RD. METHODS: A 31-item, self-administered, online questionnaire was distributed to nutrition graduates. Binary logistic regression was used to test for predictors of RD status (vs. non-RD). RESULTS: Of the 195 participants who completed the survey (37% response rate), 68% identified as an RD and 31% did not. White students had 3.8 times higher odds of being an RD (P < 0.001) compared with students of an ethnic minority. Those who had received a student loan (P = 0.033) or lived with their parents during their degree (P = 0.004) also had significantly lower odds of being an RD. The most common barrier for not completing the dietetic internship by non-RDs was that the application process was too stressful. CONCLUSIONS: Results from this study highlight the need for the dietetics field to address systemic barriers for students of ethnic minorities and low socioeconomic backgrounds, including barriers during the degree program and in the internship selection process.

ABSTRACT

Purpose: The study objectives were to (i) describe employment outcomes among Registered Dietitians (RDs) who graduated from the University of Manitoba, (ii) test for differences in employment outcomes according to graduation year, and (iii) compare preferred area of practice and geography prior to employment with past and current employment. Methods: Graduates of the Human Nutritional Sciences program (2006-2015) were invited to participate in an online survey. Data on respondent demographics, education, and employment outcomes were collected. Results: Overall, 133 (68%) respondents self-identified as RDs. RDs who had graduated between 2006 and 2011 were significantly more likely to secure employment within 6 months post-graduation compared with RDs that graduated between 2012 and 2015. Geographically, although 56% of RDs did not wish to gain experience in rural/remote communities upon graduating, 44% of these respondents reported working part- or full-time in a rural/remote location at some point during their career. Conclusion: Findings indicate that a substantial number of RDs in Manitoba are employed in a rural or remote location despite acknowledging that it is not a preferred location. Future research is needed to explore the views and experiences of new and established RDs toward rural or remote practice, including preparedness for practice.

ABSTRACT

BACKGROUND: There has been limited longitudinal research that has comprehensively evaluated possible factors in the exacerbation of inflammatory bowel disease (IBD) symptoms with or without associated inflammation. Evolving Web-based technologies facilitate frequent monitoring of patients' experiences and allow a fine-grained assessment of disease course. OBJECTIVE: We aimed to prospectively identify factors associated with symptom exacerbation and inflammation in IBD including psychological functioning, diet, health behaviors, and medication adherence. METHODS: Between June 2015 and May 2017, we enrolled adults with IBD, recruited from multiple sources, who had been symptomatically active at least once within the prior 2 years. They completed a Web-based survey every 2 weeks for 1 year and submitted a stool sample at baseline, 26 weeks, and 52 weeks. Any participant reporting a symptom exacerbation was matched to a control within the cohort, based on disease type, sex, age, and time of enrollment; both were sent a supplemental survey and stool collection kit. Biweekly surveys included validated measures of the disease course, psychological functioning, health comorbidities, and medication use. Intestinal inflammation was identified through fecal calprotectin (positive level >250 µg/g stool). RESULTS: There were 155 participants enrolled with confirmed IBD, 66.5% (103/155) with Crohn disease and 33.5% (52/155) with ulcerative colitis, of whom 98.7% (153/155) completed the study. Over the 1-year period, 47.7% (74/155) participants experienced a symptom exacerbation. The results of analyses on risk factors for symptom exacerbations are pending. CONCLUSIONS: We recruited and retained a longitudinal IBD cohort that will allow the determination of risk factors for symptom exacerbation with and without inflammation. This will increase understanding of symptom exacerbations among persons with IBD. INTERNATIONAL REGISTERED REPORT IDENTIFIER (IRRID): RR1-10.2196/11317.

ABSTRACT

BACKGROUND: A comprehensive study of what individuals with inflammatory bowel disease (IBD) are eating that encompasses food avoidance, dietary sugar consumption, and a comparison with the non-IBD Canadian population has not been documented. The aim was to analyze these interrelated dietary components. METHODS: Food avoidance and sugar intake data were collected from 319 patients with IBD enrolled in the University of Manitoba IBD Cohort Study. Diets of those with IBD (n = 256) were compared with a matched, non-IBD Canadian cohort using the nutrition questions obtained from the Canadian Health Measures Survey (CHMS). RESULTS: Food avoidance among IBD is prevalent for alcohol, popcorn, legumes, nuts, seeds, deep-fried food, and processed deli meat, with a higher prevalence among those with active IBD. Patients with active IBD also consumed significantly more portions of sports drinks and sweetened beverages compared with those with inactive disease. Compared with the non-IBD Canadian population, patients with IBD consume significantly less iron-rich food but more milk. CONCLUSIONS: Food avoidance is common among those with IBD but may be due more to personal preferences, while sugar-laden beverages may be displacing other foods higher in nutrients. The overall diet of patients with IBD differed from that of the non-IBD Canadian population, but deficiencies were observed in both groups. Considering malnutrition among persons living with IBD, nutrition education by trained dietitians as part of the IBD team is imperative to address food avoidance and overall balance nutrition as part of treating and preventing nutrition deficiencies.

ABSTRACT

BACKGROUND: The Subjective Global Assessment (SGA) is a validated nutrition assessment tool that is not commonly used to evaluate the nutritional status of patients admitted to the intensive care unit (ICU). OBJECTIVES: The aims of this study were to determine the prevalence of malnutrition in critically ill medical patients using the SGA and to determine whether the SGA was predictive of patient outcome. MATERIALS AND METHODS: A retrospective chart review was performed on 57 consecutive patients admitted to a single tertiary care medical ICU and requiring mechanical ventilation over a 6-month time period. All SGA assessments were performed by a single dietitian trained in this assessment technique. Multiple factors including patient demographics, severity of illness, length of mechanical ventilation, length of ICU stay, and mortality were abstracted from the charts. RESULTS: The prevalence of malnutrition on admission as assessed by the SGA was 35%. Severity of illness as determined by Acute Physiology and Chronic Health Evaluation II (APACHE II) score was not different between the SGA groups. Mortality rates were significantly higher in the moderately (45.5%) and severely malnourished (55.6%) groups than in the well-nourished group (10.8%; P = .004). CONCLUSION: Malnutrition on admission is common in critically ill medical patients. Malnutrition, as assessed by SGA at admission to ICU, is associated with increased mortality and thus can serve as a valuable prognostic tool in the assessment of critically ill patients. Given that that the SGA is a simple bedside assessment, it should be considered for routine use in assessing critically ill patients.

ABSTRACT

BACKGROUND: The aim of this study was to longitudinally study serum homocysteine levels in patients with Crohn's disease (CD) and ulcerative colitis (UC) in relation to disease activity and B vitamin status. METHODS: In all, 98 consecutive adult patients (age 25-55 years) with CD (n = 70) and UC (n = 28) were enrolled and assessed at three timepoints over 1 year. RESULTS: There were no significant differences in levels of homocysteine, B vitamins, or dietary intake by disease type, disease activity, or across visits. 13% of all inflammatory bowel disease (IBD) patients had elevated homocysteine at least once during the study. Nine patients with CD had fluctuating homocysteine levels during the study but these were inconsistent, ranging from within normal range to elevated levels in any individual. Six of these nine patients were persistently in remission. 30% of all IBD patients had vitamin B6 deficiency, 11% had vitamin B12 deficiency, and one patient (CD) had folate deficiency. All vitamins showed a significant correlation between intake and serum levels (B6; r = 0.46, P < 0.001, B12; r = 0.42, P < 0.001, and folate; r = 0.26, P = 0.008). There was an inverse relationship between serum homocysteine in the blood and serum vitamin B12 (r = -0.241, P = 0.017). CONCLUSIONS: Serum homocysteine was mostly normal in patients with IBD and changed minimally over time. There was no association between disease activity and elevation of serum homocysteine. 30% of patients have vitamin B6 deficiency but vitamin B6 is not associated with elevated homocysteine. The routine measurement of homocysteine is not warranted.

ABSTRACT

BACKGROUND: Malnutrition among inflammatory bowel disease (IBD) subjects is well documented in the literature and may arise from factors including inadequate dietary intake, malabsorption, and disease activity. The aims of this present study were to complete a comprehensive nutrition assessment of IBD subjects. METHODS: One hundred twenty-six consecutive adults with IBD completed anthropometric measures, 4-day food-record assessments, and biochemical markers of nutrition. RESULTS: A high prevalence of inadequate nutrient consumption was observed: vitamin E (63%), vitamin D (36%), vitamin A (26%), calcium (23%), folate (19%), iron (13%), and vitamin C (11%). Several biochemical deficiencies were also observed. The prevalence of subnormal serum levels was hemoglobin (40%), ferritin (39.2%), vitamin B(6) (29%), carotene (23.4%), vitamin B(12) (18.4%), vitamin D (17.6%), albumin (17.6%), and zinc (15.2%). Dietary intake was not correlated with serum levels in all instances; there was a highly significant correlation between diet and serum values of vitamin B(12), folate, and vitamin B(6) for all IBD subjects, independent of disease activity, and for vitamin D among all IBD subjects in remission. CONCLUSIONS: Subjects with IBD have a high rate of iron deficiency and anemia, which are most likely not secondary to diet. Supplementing with iron should be warranted only if a true iron deficiency exists. The routine evaluation of serum vitamin B(6) and vitamin D levels is recommended. Routine multivitamin supplementation is warranted in IBD in view of numerous dietary and biochemical deficiencies observed among adult IBD subjects.
