RESUMEN
INTRODUCTION: Immigrants are among the most vulnerable population groups in North America; they face multidimensional hurdles to obtain proper healthcare. Such barriers result in increased risk of developing acute and chronic conditions. Subsequently a great deal of burden is placed on the healthcare system. Community navigator programs are designed to provide culturally sensitive guidance to vulnerable populations in order to overcome barriers to accessing healthcare. Navigators are healthcare workers who support patients to obtain appropriate healthcare. This scoping review systematically searches and summarizes the literature on community navigators to help immigrant and ethnic minority groups in Canada and the United States overcome barriers to healthcare. METHODS: We systematically searched electronic databases for primary articles and grey literature. Study selection was performed following the preferred reporting items for systematic reviews and meta-analyses (PRISMA) statement. Articles were selected based on four criteria: (1) the study population was comprised of immigrants or ethnic minorities living in Canada or the United States; (2) study outcomes were related to chronic disease management or primary care access; (3) the study reported effects of community navigator intervention; (4) the study was published in English. Relevant information from the articles was extracted and reported in the review. RESULT: Only one study was found in the literature that focused on navigators for immigrants in Canada. In contrast, 29 articles were found that reported navigator intervention programs for immigrant minorities in the United States. In these studies navigators trained and guided members of several ethnic communities for chronic disease prevention and management, to undertake cancer screening as well as accessing primary healthcare. The studies reported substantial improvement in the immigrant and ethnic minority health outcomes in the United States. The single Canadian study also reported positive outcome of navigators among immigrant women. CONCLUSION: Navigator interventions have not been fully explored in Canada, where as, there have been many studies in the United States and these demonstrated significant improvements in immigrant health outcomes. With many immigrants arriving in Canada each year, community navigators may provide a solution to reduce the existing healthcare barriers and support better health outcomes for new comers.

INTRODUCTION: High-quality clinical trials are needed to establish the efficacy and safety of novel therapies for acute kidney injury (AKI) prevention. In this consensus workshop, we identified patient and caregiver priorities for recruitment, intervention delivery, and outcomes of a clinical trial of cilastatin to prevent nephrotoxic AKI. METHODS: We included adults with lived experience of AKI, chronic kidney disease, or risk factors for AKI (e.g., critical care hospitalization), and their caregivers. Using a modified nominal group technique approach, we conducted a series of hybrid in-person/virtual discussions covering 3 clinical trial topic areas: (1) consent and recruitment; (2) intervention delivery; and (3) trial outcomes. Participants voted on their top preferences in each topic area, and discussion transcripts were analyzed inductively using conventional content analysis. RESULTS: Thirteen individuals (11 patients, 2 caregivers) participated in the workshop. For consent and recruitment, participants prioritized technology enabled pre-screening and involvement of family members in the consent process. For intervention delivery, participants prioritized measures to facilitate ease of intervention administration and return visits. For trial outcomes, participants identified kidney-related and other clinical outcomes (e.g., AKI, chronic kidney disease, cardiovascular events) as top priorities. Analysis of transcripts provided insight into care team and family involvement in trial-related decisions, implications of allocation to a placebo arm, and impact of participants' experiences of AKI and critical illness. CONCLUSION: Findings from our workshop will directly inform development of a clinical trial protocol of cilastatin for nephrotoxic AKI prevention and can assist others in patient-centered approaches to AKI trial design.
RESUMEN
BACKGROUND AND AIMS: Malnutrition is a modifiable risk factor for morbidity and mortality in cirrhosis. Nutrition risk screening is recommended in cirrhosis nutrition guidelines, but is not routinely completed in practice. The patient-generated subjective global assessment short form (PG-SGA SF) is a patient-completed screen that has potential to be a substitute for more time and resource intensive nutrition screens. The aim of this cross-sectional study was to compare the PG-SGA SF and three other patient-completed screens against the nutrition assessment reference method in cirrhosis, the Royal Free Hospital subjective global assessment (RFH-SGA). We also explored whether being classified "at-risk" on a nutritional screening tool was associated with clinical outcomes of unplanned hospitalization or death. METHODS: Patients completed four nutrition screening tools with or without support from a caregiver. The RFH-SGA was carried out by a blinded registered dietitian. The four screening tools were compared against the RFH-SGA to calculate sensitivity, specificity, and positive and negative predictive value. RESULTS: A total of 121 patients were included. The PG-SGA SF screened the highest number of patients positive for malnutrition risk (52%), was the most accurate, and had the highest sensitivity. Being at risk for malnutrition on the PG-SGA SF was associated with a higher risk of unplanned hospitalization (unadjusted sHR 2.78 (95% CI 1.3-5.9), p = 0.009). CONCLUSIONS: The PG-SGA SF identifies malnutrition risk at similar or superior rates to other patient-generated screening tools in patients with cirrhosis. Our findings support its potential as a patient completed solution for identifying malnutrition risk in cirrhosis.

While children with appendicitis often have excellent clinical outcomes, some develop life-threatening complications including sepsis and organ dysfunction requiring pediatric intensive care unit (PICU) support. Our study applied a metabolomics and inflammatory protein mediator (IPM) profiling approach to determine the bio-profiles of children who developed severe appendicitis compared with those that did not. We performed a prospective case-control study of children aged 0-17 years with a diagnosis of appendicitis. Cases had severe disease resulting in PICU admission. Primary controls had moderate appendicitis (perforation without PICU); secondary controls had mild appendicitis (non-perforated). Serum samples were analyzed using Proton Nuclear Magnetic Resonance (1H NMR) Spectroscopy and Gas Chromatography-Mass Spectrometry (GC-MS); IPM analysis was performed using plasma bead-based multiplex profiling. Comparisons were made using multivariate data statistical analysis. Fifty-three children were included (15 severe, 38 non-severe). Separation between severe and moderate appendicitis demonstrated excellent sensitivity and specificity (100%, 88%; 14 compounds), separation between severe and mild appendicitis also showed excellent sensitivity and specificity (91%, 90%; 16 compounds). Biomarker patterns derived from metabolomics and IPM profiling are capable of distinguishing children with severe appendicitis from those with less severe disease. These findings provide an important first step towards developing non-invasive diagnostic tools for clinicians in early identification of children who are at a high risk of developing severe appendicitis.
RESUMEN
Background: Malnutrition is associated with adverse clinical outcomes in patients with inflammatory bowel disease (IBD), however, malnutrition screening is not routinely performed. This study aimed to identify the prevalence of malnutrition in patients with IBD and compare the accuracy of patient completed screens to a gold-standard malnutrition assessment tool: the dietitian-completed subjective global assessment (SGA). Methods: This cross-sectional study was conducted at 2 hospitals and 2 ambulatory care clinics in Alberta, Canada. Patients with IBD completed 4 malnutrition screening tools: abridged patient-generated SGA (abPG-SGA), Malnutrition Universal Screening Tool (MUST), Canadian Nutrition Screening Tool (CNST), and Saskatchewan IBD-nutrition risk (SaskIBD-NR). Risk of malnutrition was calculated for each tool and differences were compared between IBD subtype and body mass index (BMI) categories. Sensitivity and specificity, negative and positive predictive values (NPV and PPV), and area under the receiver operating characteristic curve (AUC) were calculated compared to SGA. Results: Patients with Crohn's disease (n = 149) and ulcerative colitis (n = 96) participated in this study. Overall prevalence of malnutrition using SGA was 23% and malnutrition risk for CNST, abPG-SGA, SaskIBD-NR, and MUST was 37%, 36%, 36%, and 27%, respectively. Overall, the abPG-SGA had the highest sensitivity (83%), PPV (53%), and NPV (94%), and largest AUC (0.837) compared to SGA. For patients with a BMI ≥25 kg/m2, sensitivity and PPV of the abPG-SGA decreased to 73% and 41%, respectively, with a AUC of 0.841. Conclusions: Malnutrition is prevalent in patients with IBD and using malnutrition risk screening tools such as the abPG-SGA may be useful to identify patients who would benefit from further assessment.
RESUMEN
This study examined associations between dietary intake and gut and systemic inflammation assessed by fecal calprotectin ≤ or > 100 µg/mg (FCP), C-reactive protein ≤ or > 5 mg/L (CRP) and serum cytokine profiles in Crohn's disease (CD) patients in clinical remission. A 3-month observational study was conducted at the University of Calgary in Calgary, Alberta, Canada between 2016 and 2018 in 66 outpatients with CD in clinical remission. FCP was obtained from stool samples at baseline and 3-months and serum CRP and serum cytokines were assessed at 3-months only (n = 41). Dietary intakes were collected using 3-day food records at baseline and 3-months and categorized as: PREDIMED Mediterranean diet scores (pMDS) total and individual components, the dietary inflammatory index (DII), food groups, and common micro- and macro-nutrients. Statistical models were developed to identify relationships between dietary factors and FCP, CRP and cytokine levels. Daily intake of leafy green vegetables was associated with FCP ≤ 100 µg/mg (p < 0.05). Increasing omega 6:3 ratio was associated with CRP ≤ 5 mg/L (p = 0.02). Different cytokines were significantly associated with various dietary variables. Future studies in patients with greater disease activity should be undertaken to explore these relationships.

INTRODUCTION: Assessing needs before developing continuing medical education/continuing professional development (CME/CPD) programs is a crucial step in the education process. A previous systematic literature review described a lack of objective evaluation for learning needs assessments in primary care physicians. This scoping review updates the literature on uses of objective evaluations to assess physicians' unperceived learning needs in CME/CPD. Identifying and understanding these approaches can inform the development of educational programs that are relevant to clinical practice and patient care. The study objectives were to (1) scope the literature since the last systematic review published in 1999; (2) conduct a comprehensive search for studies and reports that explore innovative tools and approaches to identify physicians' unperceived learning needs; (3) summarize, compare, and classify the identified approaches; and (4) map any gaps in the literature to identify future areas of research. METHODS: A scoping review was used to "map" the literature on current knowledge regarding approaches to unperceived needs assessment using conceptual frameworks for planning and assessing CME/CPD activities. RESULTS: Two prominent gaps were identified: (1) performance-based assessment strategies are highly recommended in nonresearch articles yet have low levels of implementation in published studies and (2) analysis of secondary data through patient input or environmental scanning is emphasized in grey literature implementation strategies more so than in peer-reviewed theoretical and research articles. DISCUSSION: Future evaluations should continue to incorporate multiple strategies and focus on making unperceived needs assessments actionable by describing strategies for resource management.

BACKGROUND AND AIMS: Crohn's disease [CD] is associated with alterations in gut microbial composition and function. The present controlled-intervention study investigated the relationship between patterns of dietary intake and baseline gut microbiota in CD patients in remission and examined the effects of a dietary intervention in patients consuming a non-diversified diet [NDD]. METHODS: Forty outpatients with quiescent CD were recruited in Calgary, Alberta, Canada. Based on 3-day food records, patients consuming a lower plant-based and higher red and processed meat-based diet were assigned to the NDD group [nâ =â 15] and received a 12-week structured dietary intervention; all other patients were assigned to the diversified diet [DD] control group [nâ =â 25] and received conventional management. Faecal microbiota composition, short chain fatty acids [SCFAs] and calprotectin were measured. RESULTS: At baseline the NDD and DD groups had a different faecal microbial beta-diversity [pâ =â 0.003, permutational multivariate analysis of variance]. The NDD group had lower Faecalibacterium and higher Escherichia/Shigella relative abundances compared to the DD group [3.3â ±â 5.4% vs. 8.5â ±â 10.6%; 6.9â ±â 12.2% vs. 1.6â ±â 4.4%; pâ ≤â 0.03, analysis of covariance]. These two genera showed a strong negative correlation [rs = -0.60, qâ =â 0.0002]. Faecal butyrate showed a positive correlation with Faecalibacterium [rs = 0.52, qâ =â 0.002], and an inhibitory relationship with Escherichia/Shigella abundance [four-parameter sigmoidal model, R = -0.83; rs = -0.44, qâ =â 0.01], respectively. After the 12 weeks of dietary intervention, no difference in microbial beta-diversity between the two groups was observed [pâ =â 0.43]. The NDD group demonstrated an increase in Faecalibacterium [pâ <â 0.05, generalized estimated equation model], and resembled the DD group at the end of the intervention [pâ =â 0.84, t-test with permutation]. We did not find an association of diet with faecal SCFAs or calprotectin. CONCLUSIONS: Dietary patterns are associated with specific gut microbial compositions in CD patients in remission. A diet intervention in patients consuming a NDD modifies gut microbial composition to resemble that seen in patients consuming a DD. These results show that diet is important in shaping the microbial dysbiosis signature in CD towards a balanced community.

GOALS: The goal of this study was to develop a multi-disciplinary consensus of nutrition care priorities for implementation in an IBD nutrition center of excellence (COE). BACKGROUND: The role for nutrition care in inflammatory bowel disease is broad and encompasses multiple domains. Gaps exist in the published literature around best nutrition care practices in inflammatory bowel disease and highlight the need for an evidence based approach acceptable to patients, and generalizable to a wide inflammatory bowel disease population. STUDY: Twelve health leaders in inflammatory bowel disease care attended a 1-day retreat. Two focus groups were completed using traditional focus group methodology for the first half of the retreat and a World Café method for the second half. Data analysis included review of analytic memos and conceptual analysis completed at the time of discussion, theme identification and team consensus for conceptual development. RESULTS: Three primary themes were identified as the main pillars of a COE in an IBD nutrition center of excellence. These include: a) excellence in clinical care, b) novel discovery and research, and c) knowledge translation to patients and practitioners. The key initial steps identified in this study included standardizing malnutrition screening and support while creating an environment where nutrition therapy is included as a standard of care, developing and examining the effectiveness of novel diet therapies, and translating knowledge to build capacity among care providers and patients. CONCLUSIONS: Using a 1-day retreat to identify a future direction for a center focused on nutrition excellence and align our coalition towards common goals was a successful strategy to develop consensus and identify nutrition care priorities for action.
RESUMEN
The primary objective of this study was to explore the macro- and micro-nutrient intakes and dietary patterns of patients with Crohn's disease (CD). Secondary objectives were to (a) compare the micronutrient intakes of CD patients with a representative sample of individuals, (b) describe the macro- and micronutrient intakes of male and female CD patients, and (c) describe Mediterranean diet scores (P-MDS) of male and female CD patients in remission that were recruited from an inflammatory bowel disease (IBD) clinic in Calgary, AB. Consecutive patients with ileal and/or colonic CD in endoscopic remission were recruited for participation in this cross-sectional study. Sixty-seven patients were enrolled with a mean age of 45, and a Body Mass Index (BMI) ≥ 25. Compared with the representative sample, patients with CD had similar energy, protein, carbohydrate, and total fat intake. However, polyunsaturated fats (PUFA), omega-6 and 3, and monounsaturated fats (MUFA) were lower in CD patients and dietary fiber intake was higher (p < 0.05). Vitamins C, D, thiamin, niacin, magnesium, phosphorus, zinc, and potassium were all significantly lower in all CD patients when compared to the representative sample (p < 0.05). Few patients with CD met the P-MDS criteria and overall scores were low (mean 4.5, Standard Deviation (SD) = 1.1 in males and 4.7, SD = 1.8 in females). The CD patients in this study had suboptimal dietary intakes and patterns and these data may be used to inform future dietary interventions in this population to improve intake.

Various limitations hinder the timely and accurate diagnosis of appendicitis in pediatric patients. The present study aims to investigate the potential of metabolomics and cytokine profiling for improving the diagnosis of pediatric appendicitis. Serum and plasma samples were collected from pediatric patients for metabolic and inflammatory mediator analyses respectively. Targeted metabolic profiling was performed using Proton Nuclear Magnetic Resonance Spectroscopy and Flow Injection Analysis Mass Spectrometry/Mass Spectrometry and targeted cytokine/chemokine profiling was completed using a multiplex platform to compare children with and without appendicitis. Twenty-three children with appendicitis and 35 control children without appendicitis from the Alberta Sepsis Network pediatric cohorts were included. Metabolomic profiling revealed clear separation between the two groups with very good sensitivity (80%), specificity (97%), and AUROC (0.93 ± 0.05) values. Inflammatory mediator analysis also distinguished the two groups with high sensitivity (82%), specificity (100%), and AUROC (0.97 ± 0.02) values. A biopattern comprised of 9 metabolites and 7 inflammatory compounds was detected to be significant for the separation between appendicitis and control groups. Integration of these 16 significant compounds resulted in a combined metabolic and cytokine profile that also demonstrated strong separation between the two groups with 81% sensitivity, 100% specificity and AUROC value of 0.96 ± 0.03. The study demonstrated that metabolomics and cytokine mediator profiling is capable of distinguishing children with appendicitis from those without. These results suggest a potential new approach for improving the identification of appendicitis in children.

Multiplexed profiling approaches including various 'omics' platforms are becoming a new standard of biomarker development for disease diagnosis and prognosis. The present study applied an integrated metabolomics and cytokine profiling approach as a potential aid to the identification of pediatric appendicitis. Metabolic analysis using serum (n = 121) and urine (n = 102) samples, and cytokine analysis using plasma (n = 121) samples from children presenting to the Emergency Department with abdominal pain were performed. Comparisons between children with appendicitis vs. non-appendicitis abdominal pain, and with perforated vs. non-perforated appendicitis were made using multivariate statistics. Serum and urine biomarker patterns were statistically significantly different between groups. The combined serum metabolomics and inflammatory mediator model revealed clear separation between appendicitis and non-appendicitis abdominal pain (AUROC: 0.92 ± 0.03) as well as for perforated and non-perforated appendicitis (AUROC: 0.88 ± 0.05). Urine metabolic analysis also demonstrated distinction between the groups appendicitis and non-appendicitis abdominal pain (AUROC: 0.85 ± 0.04), and perforated and non-perforated appendicitis (AUROC: 0.98 ± 0.02). In children presenting to the Emergency Department with abdominal pain, metabolomics and inflammatory mediator profiling are capable of distinguishing children with appendicitis from those without. The approach also differentiates between severities of disease. These results provide an important first step towards a potential aid for improving appendicitis identification.

Knowledge translation is an essential and emerging arena in healthcare research. It is the process of aiding the application of research knowledge into clinical practice or policymaking. Individuals at all levels of the health care system, including patients, healthcare professionals, and policymakers, are affected by the gaps that exist between research evidence and practice; the process of knowledge translation plays a role in bridging these gaps and incorporating high-quality clinical research into decision-making. Cardiovascular disease (CVD) management is a crucial area of healthcare where information gaps are known to exist. Although Japan has one of the lowest risks and mortality rates from CVDs, an increasing trend of cardiovascular incidence and changes in the risk factor conditions have been observed in recent years. This article provides an overview of knowledge translation and its importance in the cardiovascular health of the Japanese population, and describes the key steps of a typical knowledge translation strategy.

BACKGROUND: Diabetes is one of the most challenging chronic health conditions in the current era. Diabetes-related foot problems need proper patient education, and social media could a play role to disseminate proper information. METHOD: A systematic search was performed on Facebook groups using the key words "diabetes foot care", "diabetes foot", "diabetes foot management" and "podiatric care". The search resulted in 57 groups and detailed activity information was collected from those groups. Usefulness of each relevant post was determined. Regression analysis was performed to explore the factors associated with the level of usefulness of diabetes foot care-related Facebook groups. RESULTS: Our search resulted in a total of 16 eligible diabetes foot care-related Facebook groups with a total of 103 eligible posts. The average number of group members for the selected groups were 265.75 with an interquartile range of 3.5-107.75. Of the total 103 timeline posts, 45.6% posts were categorized as useful, while the remaining posts were not useful. Top mentioned diabetes foot care practice was "Checking feet daily". Multivariable logistic regression analysis showed that the level of usefulness of diabetes foot care-related Facebook groups were significantly associated with the type of posts and no association was found with presence of "likes" and presence of comment. CONCLUSION: Facebook being a widely used social networking system, patient welfare organizations, doctors, nurses and podiatrists could use this platform to provide support to educating diabetes patients and their caregivers by disseminating useful and authentic knowledge and information related to diabetes foot care.

Jute (Corchorus sp.) is one of the most important sources of natural fibre, covering â¼80% of global bast fibre production1. Only Corchorus olitorius and Corchorus capsularis are commercially cultivated, though there are more than 100 Corchorus species2 in the Malvaceae family. Here we describe high-quality draft genomes of these two species and their comparisons at the functional genomics level to support tailor-designed breeding. The assemblies cover 91.6% and 82.2% of the estimated genome sizes for C. olitorius and C. capsularis, respectively. In total, 37,031 C. olitorius and 30,096 C. capsularis genes are identified, and most of the genes are validated by cDNA and RNA-seq data. Analyses of clustered gene families and gene collinearity show that jute underwent shared whole-genome duplication â¼18.66â million years (Myr) ago prior to speciation. RNA expression analysis from isolated fibre cells reveals the key regulatory and structural genes involved in fibre formation. This work expands our understanding of the molecular basis of fibre formation laying the foundation for the genetic improvement of jute.

To summarize information obtained from original research about barriers to access of primary healthcare by Canadian immigrants' and to identify research gaps. Electronic databases of primary research articles and grey literature were searched without restricting the time period. The preferred reporting items for systematic reviews and meta-analyses statement was followed for literature selection. Articles were selected based on three criteria: (a) the study population was Canadian legal immigrant(s), (b) the research was about the barriers to accessing primary healthcare in Canada, and (c) the article was written in English. Relevant information from the articles was extracted into tabular format and classified for thematic analysis. Identified barriers were grouped into five themes: cultural, communication, socio-economic status, healthcare system structure and immigrant knowledge. The barriers to accessing primary healthcare in each of these categories can provide insight and subsequent direction for changes needed to improve immigrant care and mitigate their deterioration in health status. The demographic and ethno-cultural distributions of the study populations across the provinces highlight the need to expand research to encompass more varied immigrant groups across more regions of Canada, including more research on male immigrants and immigrant seniors, and to increase research related to health care providers' perspectives on the barriers.

Over one billion Muslims worldwide fast during the month of Ramadan. Ramadan fasting brings about some changes in the daily lives of practicing Muslims, especially in their diet and sleep patterns, which are associated with the risk of cardiovascular diseases. Over the years, many original studies have made the effort to identify the possible impact of the Ramadan fast on cardiovascular diseases. This systematic review and meta-analysis is an attempt to present the summary of key findings from those articles and an appraisal of selected literature. A systematic search using keywords of ";Ramadan fasting" and ";cardiovascular diseases" was conducted in primary research article and gray-literature repositories, in combination with hand searching and snow balling. Fifteen studies were finally selected for data extraction on the outcomes of stroke, myocardial infarction, and congestive heart failure. The analysis revealed that the incidence of cardiovascular events during the Ramadan fast was similar to the nonfasting period. Ramadan fast is not associated with any change in incidence of acute cardiovascular disease.
RESUMEN
The Burkholderia cepacia complex (Bcc) is a collection of closely related, genetically distinct, ecologically diverse species known to cause life-threatening infections in cystic fibrosis (CF) patients. By virtue of a flexible genomic structure and diverse metabolic activity, Bcc bacteria employ a wide array of virulence factors for pathogenesis in CF patients and have developed resistance to most of the commonly used antibiotics. However, the mechanism of pathogenesis and antibiotic resistance is still not fully understood. This mini review discusses the established and potential virulence determinants of Bcc and some of the contemporary strategies including transcriptomics and proteomics used to identify these traits. We also propose the application of metabolic profiling, a cost-effective modern-day approach to achieve new insights.
