Partnering with organisations beyond academia through strategic collaboration for research and mobilisation in immigrant/ethnic-minority communities.

Community-engaged research needs involving community organisations as partners in research. Often, however, considerations regarding developing a meaningful partnership with community organisations are not highlighted. Researchers need to identify the most appropriate organisation with which to engage and their capacity to be involved. Researchers tend to involve organisations based on their connection to potential participants, which relationship often ends after achieving this objective. Further, the partner organisation may not have the capacity to contribute meaningfully to the research process. As such, it is the researchers' responsibility to build capacity within their partner organisations to encourage more sustainable and meaningful community-engaged research. Organisations pertinent to immigrant/ethnic-minority communities fall into three sectors: public, private and non-profit. While public and private sectors play an important role in addressing issues among immigrant/ethnic-minority communities, their contribution as research partners may be limited. Involving the non-profit sector, which tends to be more accessible and utilitarian and includes both grassroots associations (GAs) and immigrant service providing organisations (ISPOs), is more likely to result in mutually beneficial research partnerships and enhanced community engagement. GAs tend to be deeply rooted within, and thus are often truly representative of, the community. As they may not fully understand their importance from a researcher's perspective, nor have time for research, capacity-building activities are required to address these limitations. Additionally, ISPOs may have a different understanding of research and research priorities. Understanding the difference in perspectives and needs of these organisations, building trust and creating capacity building opportunities are important steps for researchers to consider towards building durable partnerships.

The 21-Year Trend of Stroke Incidence in a General Japanese Population: Results from the Takashima Stroke Registry, 1990-2010.

INTRODUCTION: Since the 1960s, the stroke morality rate in Japan has declined significantly. Although several risk factors for stroke have become more evident due to increasingly Westernized lifestyle, there have been no population-based registry data on recent time trends in stroke incidence in Japan. The purpose of this study is to determine these trends in stroke incidence using a population-based registry. METHODS: Data were obtained from the Takashima Stroke Registry, which covers approximately 50,000 residents in Takashima City, Japan. The age- and sex-standardized stroke incidence rate was estimated using the direct method. Average annual relative changes of stroke incidence were estimated using Poisson regression models. RESULTS: We identified a total of 2,371 patients with first-ever stroke during the period 1990-2010. Crude incidence rates of total stroke (per 100,000 person-years) were 225 in the early period (1990-2001) and 187 in the late period (2002-2010), and the mean age at onset of stroke increased from 71.9 years in the early period to 74.8 years in the late period. Age- and sex-standardized incidence rates of stroke (per 100,000 person-years) decreased from 327 in the early part of this study period and 206 in the later period. During the 21-year period, age- and sex-standardized average annual relative reduction in stroke incidence was statistically significant (-3.7% per year). When stratified into early and late periods, the adjusted annual relative reduction in stroke incidence was observed during the early period (-2.1% per year), and there were no significant changes during the late period. CONCLUSIONS: In this population-based registry, there was a significant reduction in incidence of stroke from 1990 to 2010. Although the speed of reduction in stroke incidence appears to have slowed down after 2000, continuous public health measures are required to provide further protection against stroke.

Assessing the Relationship Between High-sensitivity C-reactive Protein and Kidney Function Employing Mendelian Randomization in the Japanese Community-based J-MICC Study.

BACKGROUND: Inflammation is thought to be a risk factor for kidney disease. However, whether inflammatory status is either a cause or an outcome of chronic kidney disease remains controversial. We aimed to investigate the causal relationship between high-sensitivity C-reactive protein (hs-CRP) and estimated glomerular filtration rate (eGFR) using Mendelian randomization (MR) approaches. METHODS: A total of 10,521 participants of the Japan Multi-institutional Collaborative Cohort Study was analyzed in this study. We used two-sample MR approaches (the inverse-variance weighted (IVW), the weighted median (WM), and the MR-Egger method) to estimate the effect of genetically determined hs-CRP on kidney function. We selected four and three hs-CRP associated single nucleotide polymorphisms (SNPs) as two instrumental variables (IV): IVCRP and IVAsian, based on SNPs previously identified in European and Asian populations. IVCRP and IVAsian explained 3.4% and 3.9% of the variation in hs-CRP, respectively. RESULTS: Using the IVCRP, genetically determined hs-CRP was not significantly associated with eGFR in the IVW and the WM methods (estimate per 1 unit increase in ln(hs-CRP), 0.000; 95% confidence interval [CI], -0.019 to 0.020 and -0.003; 95% CI, -0.019 to 0.014, respectively). For IVAsian, we found similar results using the IVW and the WM methods (estimate, 0.005; 95% CI, -0.020 to 0.010 and -0.004; 95% CI, -0.020 to 0.012, respectively). The MR-Egger method also showed no causal relationships between hs-CRP and eGFR (IVCRP: -0.008; 95% CI, -0.058 to 0.042; IVAsian: 0.001; 95% CI, -0.036 to 0.036). CONCLUSION: Our two-sample MR analyses with different IVs did not support a causal effect of hs-CRP on eGFR.

Involving im/migrant community members for knowledge co-creation: the greater the desired involvement, the greater the need for capacity building.

Researchers need to observe complex problems from various angles and contexts to create workable, effective and sustainable solutions. For complex societal problems, including health and socioeconomic disparities, cross-sectoral collaborative research is crucial. It allows for meaningful interaction between various actors around a particular real-world problem through a process of mutual learning. This collaboration builds a sustainable, trust-based partnership among the stakeholders and allows for a thorough understanding of the problem through a solution-oriented lens. While the created knowledge benefits the community, the community is generally less involved in the research process. Often, community members are engaged to collect data or for consultancy and knowledge dissemination; however, they are not involved in the actual research process, for example, developing a research question and using research tools such as conducting focus groups, analysis and interpretation. To be involved on these levels, there is a need for building community capacity for research. However, due to a lack of funds, resources and interest in building capacity on the part of both researchers and the community, deeper and meaningful involvement of community members in research becomes less viable. In this article, we reflect on how we have designed our programme of research-from involving community members at different levels of the research process to building capacity with them. We describe the activities community members participated in based on their needs and capacity. Capacity-building strategies for each level of involvement with the community members are also outlined.

Meaningful and deep community engagement efforts for pragmatic research and beyond: engaging with an immigrant/racialised community on equitable access to care.

Primary healthcare access is one of the crucial factors that ensures the health and well-being of a population. Immigrant/racialised communities encounter a myriad of barriers to accessing primary healthcare. As global migration continues to grow, the development and practice of effective strategies for research and policy regarding primary care access are warranted. Many studies have attempted to identify the barriers to primary care access and recommend solutions. However, top-down approaches where the researchers and policy-makers 'prescribe' solutions are more common than community-engaged approaches where community members and researchers work hand-in-hand in community-engaged research to identify the problems, codevelop solutions and recommend policy changes. In this article, we reflect on a comprehensive community-engaged research approach that we undertook to identify the barriers to equitable primary care access among a South Asian (Bangladeshi) immigrant community in Canada. This article summarised the experience of our programme of research and describes our understanding of community-engaged research among an immigrant/racialised community that meaningfully interacts with the community. In employing the principles of community-based participatory research, integrated knowledge translation and human centred design, we reflect on the comprehensive community-engaged research approach we undertook. We believe that our reflections can be useful to academics while conducting community-engaged research on relevant issues across other immigrant/racialised communities.

Advancing bibliometric assessment of research productivity: an analysis of US Departments of Family Medicine.

INTRODUCTION Measurement of family medicine research productivity has lacked the replicable methodology needed to document progress. AIM In this study, we compared three methods: (1) faculty-to-publications; (2) publications-to-faculty; and (3) department-reported publications. METHODS In this cross-sectional analysis, publications in peer-reviewed, indexed journals for faculty in 13 US family medicine departments in 2015 were assessed. In the faculty-to-publications method, department websites to identify faculty and Web of Science to identify publications were used. For the publications-to-faculty method, PubMed's author affiliation field were used to identify publications, which were linked to faculty members. In the department-reported method, chairs provided lists of faculty and their publications. For each method, descriptive statistics to compare faculty and publication counts were calculated. RESULTS Overall, 750 faculty members with 1052 unique publications, using all three methods combined as the reference standard, were identified. The department-reported method revealed 878 publications (84%), compared to 616 (59%) for the faculty-to-publications method and 412 (39%) for the publication-to-faculty method. Across all departments, 32% of faculty had any publications, and the mean number of publications per faculty was 1.4 (mean of 4.4 per faculty among those who had published). Assistant Professors, Associate Professors, Professors and Chairs accounted for 92% of all publications. DISCUSSION Online searches capture a fraction of publications, but also capture publications missed through self-report. The ideal methodology includes all three. Tracking publications is important for quantifying the return on our discipline's research investment.

Hypercholesterolemia and Lifetime Risk of Coronary Heart Disease in the General Japanese Population: Results from the Suita Cohort Study.

AIM: Lifetime risk (LTR) is a measure of disease burden, which presents the probability of occurrence of a specific disease in the remaining lifetime of a group of people for a given index age. This measure is useful for presenting the risk dynamics of a disease at the population level, which constitutes important public health information toward prevention. To date, there have been no studies investigating the LTR for coronary heart diseases (CHDs) in relation to hypercholesterolemia in Asian populations. Therefore, we estimated the LTR of CHDs according to serum low-density lipoprotein cholesterol (LDL-C). METHODS: The participants included in this study were 2,559 men and 2,848 women, enrolled in the Suita Cohort Study of urban residents followed up from 1989 to 2007 for a total of 69,823 person-years. We estimated the sex- and index-age-specific LTR for the first CHD event among participants with or without hypercholesterolemia (LDL-C ≥ 160 mg/dL), accounting for the competing risk for mortality. RESULTS: For men with hypercholesterolemia, the LTR was 47.2% (95% confidence interval [CI]: 29.3-65.1%) and 44.5% (95% CI: 21.4-68.5%) for those aged 45 and 75, respectively. The LTRs of women with hypercholesterolemia were also higher than of those without hypercholesterolemia. However, their LTRs were lower for all index ages compared to men. These results did not differ for hypercholesterolemia defined by non-high-density lipoprotein cholesterol. CONCLUSIONS: The presence of hypercholesterolemia increases the LTR for CHDs in the Japanese population, especially in men. This estimate can be used in preventive knowledge translation efforts at the population level.

Genome-Wide Association Study of Renal Function Traits: Results from the Japan Multi-Institutional Collaborative Cohort Study.

BACKGROUND: Chronic kidney disease (CKD) is a rapidly growing, worldwide public health problem. Recent advances in genome-wide-association studies (GWAS) revealed several genetic loci associated with renal function traits worldwide. METHODS: We investigated the association of genetic factors with the levels of serum creatinine (SCr) and the estimated glomerular filtration rate (eGFR) in Japanese population-based cohorts analyzing the GWAS imputed data with 11,221 subjects and 12,617,569 variants, and replicated the findings with the 148,829 hospital-based Japanese subjects. RESULTS: In the discovery phase, 28 variants within 4 loci (chromosome [chr] 2 with 8 variants including rs3770636 in the LDL receptor related protein 2 gene locus, on chr 5 with 2 variants including rs270184, chr 17 with 15 variants including rs3785837 in the BCAS3 gene locus, and chr 18 with 3 variants including rs74183647 in the nuclear factor of -activated T-cells 1 gene locus) reached the suggestive level of p < 1 × 10-6 in association with eGFR and SCr, and 2 variants on chr 4 (including rs78351985 in the microsomal triglyceride transfer protein gene locus) fulfilled the suggestive level in association with the risk of CKD. In the replication phase, 25 variants within 3 loci (chr 2 with 7 variants, chr 17 with 15 variants and chr 18 with 3 variants) in association with eGFR and SCr, and 2 variants on chr 4 associated with the risk of CKD became nominally statistically significant after Bonferroni correction, among which 15 variants on chr 17 and 3 variants on chr 18 reached genome-wide significance of p < 5 × 10-8 in the combined study meta-analysis. The associations of the loci on chr 2 and 18 with eGFR and SCr as well as that on chr 4 with CKD risk have not been previously reported in the Japanese and East Asian populations. CONCLUSION: Although the present GWAS of renal function traits included the largest sample of Japanese participants to date, we did not identify novel loci for renal traits. However, we identified the novel associations of the genetic loci on chr 2, 4, and 18 with renal function traits in the Japanese population, suggesting these are transethnic loci. Further investigations of these associations are expected to further validate our findings for the potential establishment of personalized prevention of renal disease in the Japanese and East Asian populations.

Sociodemographic Correlates of Clinical Laboratory Test Expenditures in a Major Canadian City.

OBJECTIVES: The increasing cost of clinical laboratory testing is a challenge in our health care system. This study aims to calculate the annual clinical laboratory test costs attributed to patients in a major Canadian city and to correlate them to their sociodemographic variables. METHODS: Retrospective cohort study involving patients who received clinical chemistry, hematology, and microbiology tests in 2011 in Calgary, Canada (n = 610,409). Test volumes were obtained from a laboratory informatics database. Total expenditures per patient were calculated using estimated test costs and then combined with the 2011 Canadian Census Household Survey results to infer sociodemographic correlates. RESULTS: While more women received laboratory testing (58.4%), men had slightly higher testing costs per capita. Except for Chinese, visible minority and Aboriginal populations had higher testing costs. There was an inverse correlation between testing cost and household income, and accordingly, higher costs were found in those without postsecondary education and the unemployed. Furthermore, hotspot mapping revealed the geographical distribution of patient test costs within the city. CONCLUSIONS: There is variation in testing costs for patients among different sociodemographic variables.

Diabetes and lifetime risk of coronary heart disease.

INTRODUCTION: Epidemiological estimate lifetime risk (LTR) is a measure that expresses the probability of disease in the remaining lifetime for individuals of a specific index age. These estimates can be useful for general audience targeted knowledge translation activities against diabetes. There are only a few reports on lifetime of impact of diabetes on coronary heart disease (CHD) events. METHODS: The Suita Study, a cohort study of cardiovascular diseases (CVD), was established in 1989. We included all participants who were CVD free at baseline. Age (in years) was used as the time scale. Age-specific incidence rates were calculated with person-year method within ten-year bands. We estimated the sex and index-age specific LTR of first-ever CHD with taking the competing risk of death into account. RESULTS: We followed 5559 participants without CHD history during 1989-2007 for 71,745.4 person-years. At age 40 years the competing risk of death adjusted LTR for all CHD were 16.61% for men without diabetes and 21.06% for men with diabetes. Therefore the LTD for CHD was higher by 4.45% for men with diabetes compared to men without. The competing risk adjusted LTR of CHD at 40 years of aged women was 9.18% for without diabetes and 14.21% for with diabetes. This increased LTR of CHD for diabetic patients were observed among both men and women across all index ages. CONCLUSION: In this urban community based population we observed that diabetes has significant effect on the residual LTR of CHD among both men and women of middle age. This easy understandable knowledge can be used as important indexes to assist public health education and planning.

Risk of stroke and heart failure attributable to atrial fibrillation in middle-aged and elderly people: Results from a five-year prospective cohort study of Japanese community dwellers.

BACKGROUND: The relative and absolute risks of stroke and heart failure attributable to atrial fibrillation (AF) have not been sufficiently examined. METHODS: A prospective study of 23,731 community-dwelling Japanese individuals was conducted. Participants were divided into two groups based on the presence or absence of prevalent AF (n = 338 and n = 23,393, respectively). Excess events (EE) due to AF and relative risks (RRs) determined using the non-AF group as the reference for incident stroke and heart failure were estimated using Poisson regression stratified by age groups (middle-aged: 40-69 years old; elderly: 70 years of age or older) after adjustment for sex and age. RESULTS: There were 611 cases of stroke and 98 cases of heart failure during the observation period (131,088 person-years). AF contributed to a higher risk of stroke both in middle-aged individuals (EE 10.4 per 1000 person-years; RR 4.88; 95% confidence interval [CI], 2.88-8.29) and elderly individuals (EE 18.3 per 1000 person-years; RR 3.05; 95% CI, 2.05-4.54). AF also contributed to a higher risk of heart failure in middle-aged individuals (EE 3.7 per 1000 person-years; RR 8.18; 95% CI, 2.41-27.8) and elderly individuals (EE 15.4 per 1000 person-years; RR 7.82; 95% CI, 4.11-14.9). Results obtained from multivariate-adjusted analysis were similar (stroke: EE 8.9 per 1000 person-years; RR 4.40; 95% CI, 2.57-7.55 in middle-aged and EE 17.4 per 1000 person-years; RR 2.97; 95% CI, 1.99-4.43 in elderly individuals; heart failure: EE 3.1 per 1000 person-years; RR 7.22; 95% CI, 2.06-25.3 in middle-aged and EE 14.1 per 1000 person-years; RR 7.41; 95% CI, 3.86-14.2 in elderly individuals). CONCLUSIONS: AF increased the risk of stroke by the same magnitude as that reported previously in Western countries. AF increased the RR of heart failure more than that in Western populations.

Diabetes and lifetime risk of stroke and subtypes in an urban middle-aged population.

AIMS: Lifetime risk (LTR) is defined as the cumulative probability of developing a disease in one's remaining lifetime from a given index age. The impact of diabetes on the LTR of stroke events in Asians, where stroke incidence is higher than for Westerners, has not been estimated yet. These estimates can be useful for diabetes knowledge translation activities. METHODS: All participants who were stroke-free at baseline in the Suita Study, a cohort study of cardiovascular diseases in Japan, were included in the study sample. Age, in years, was used as the time-scale. Age-specific incidence rates were calculated using the person-years method within five-year bands. We estimated the sex- and index-age-specific LTR of first-ever stroke accounting for the competing risk of death. RESULTS: In this cohort study, we followed 5515 participants from 1989 to 2007 for 71,374.23 person-years. At age 40, the LTRs, adjusted for competing risk of death, for all strokes were 15.98% for men without diabetes and 26.64% for men with diabetes. The LTR for stroke was 10.66% higher for men with diabetes than men without diabetes. For women of same index age, the LTR of stroke was 17.29% and 30.72% with diabetes and without diabetes, respectively. The difference in LTR between persons with diabetes and without diabetes was 13.43%. This increased LTR of strokes for persons with diabetes was observed among both men and women across all index ages. Similar results were observed for cerebral infarction stroke subtype. CONCLUSIONS: In this urban community-based population we observed that diabetes has a significant effect on the residual LTR of stroke for both men and women of middle age. This knowledge can be used to inform public health education and planning.

Lifetime risk of diabetes among First Nations and non-First Nations people.

BACKGROUND: Lifetime risk is a relatively straightforward measure used to communicate disease burden, representing the cumulative risk of an outcome during the remainder of an individual's life starting from a disease-free index age. We estimated the lifetime risk of diabetes among men and women in both First Nations and non-First Nations populations using a cohort of adults in a single Canadian province. METHODS: We used a population-based cohort consisting of Alberta residents from 1997 to 2008 who were free of diabetes at cohort entry to estimate the lifetime risk of diabetes among First Nations and non-First Nations people. We calculated age-specific incidence rates with the person-year method in 5-year bands. We estimated the sex- and index-age-specific lifetime risk of incident diabetes, after adjusting for the competing risk of death. RESULTS: The cohort included 70 631 First Nations and 2 732 214 non-First Nations people aged 18 years or older. The lifetime risk of diabetes at 20 years of age was 75.6% among men and 87.3% among women in the First Nations group, as compared with 55.6% among men and 46.5% among women in the non-First Nations group. The risk was higher among First Nations people than among non-First Nations people for all index ages and for both sexes. Among non-First Nations people, men had a higher lifetime risk of diabetes than women across all index ages. In contrast, among First Nations people, women had a higher lifetime risk than men across all index ages. INTERPRETATION: About 8 in 10 First Nations people and about 5 in 10 non-First Nations people of young age will develop diabetes in their remaining lifetime. These population-based estimates may help health care planners and decision-makers set priorities and increase public awareness and interest in the prevention of diabetes.

Hospice care in Calgary: Survey of family physicians on their knowledge, experience, and attitudes.

OBJECTIVE: To explore Calgary family physicians' knowledge about hospices, their attitudes toward the referral process, and their understanding of barriers to referral for hospice care. DESIGN: Surveys were mailed to 400 randomly selected participants. The survey contained 18 questions related to hospice care, physician experience, attitudes, and perceived barriers to making a hospice referral. SETTING: Calgary, Alta. PARTICIPANTS: Family physicians. MAIN OUTCOME MEASURES: Survey responses were analyzed quantitatively using the (2) goodness-of-fit test, Kruskal-Wallis tests, and logistic regression analyses to examine univariate associations. Qualitative analysis of open-ended questions was done by content analysis and thematic coding. RESULTS: In total, 104 surveys were mailed back. Family physicians agreed that palliative care in a hospice setting can greatly improve quality of life for patients, but only 2 of 6 knowledge questions about hospice care were answered correctly by most. Family physicians with special areas of interest or subspecialties were more likely to feel well-informed about hospice referrals (P = .017), indicated a higher comfort level discussing hospice and palliative care (P = .030), and were less likely to defer discussing it with patients (P = .023). Physicians with a special interest in palliative medicine were more likely to correctly answer the knowledge questions (P < .034) and to be familiar with the referral process (P < .001), patient eligibility (P < .001), and the palliative home care program (P = .003). Qualitative analysis revealed support for palliative home care and consultation services but concerns about caregiver coping and family issues. Concerns about disengagement of family physicians and uncertainty about the referral process are obstacles to referral. CONCLUSION: While Calgary family physicians are appreciative of hospice care, there are knowledge gaps. It is important to engage family physicians in the referral process.

Ventricular tachyarrhythmia and sudden cardiac death with domperidone use in Parkinson's disease.

AIM: Domperidone is preferentially used over other antiemetic agents to treat digestive symptoms in Parkinson's disease (PD). Concerns have been raised regarding an increased risk of ventricular tachyarrhythmia and sudden cardiac death (VT/SCD) associated with domperidone in the general population. However, the risk in PD is unknown. METHODS: We conducted a multicentre retrospective cohort study using administrative databases from seven Canadian provinces and the UK Clinical Practice Research Datalink. Using a nested case-control analysis, we estimated the rate ratios (RRs) of VT/SCD associated with domperidone use compared to no use in patients newly-diagnosed with PD. VT/SCD events were identified using administrative medical records and vital statistics with a manual review of all potential cases. Meta-analytic methods were used to estimate overall effects across sites. RESULTS: Among 214 962 patients with PD, 2907 cases of VT/SCD were identified during 886 581 person-years of follow-up (incidence rate 3.28 per 1000 persons per year). Current use of domperidone was associated with a non-statistically significant 22% increased risk of VT/SCD (RR 1.22; 95% CI 0.99-1.50) compared with no use. The risk was significantly elevated in those with a history of cardiovascular disease (RR 1.38; 95% CI 1.07-1.78), but not in those without (RR 1.21; 95% CI 0.81-1.81). Dose and duration of use did not affect the magnitude of the risk. CONCLUSION: Domperidone use may increase the risk of VT/SCD in patients with PD, particularly those with a history of cardiovascular disease. This risk may be underestimated because of imprecision in identifying VT/SCD events.

Impact of hypertension on the lifetime risk of coronary heart disease.

The lifetime risk estimate conveys the probability of disease in the remaining lifetime for an index age. These estimates may be useful for general audience-targeted knowledge translation activities against hypertension. There are only a few reports on the impact of hypertension on the lifetime risk of cardiovascular events. The Suita Study, a cohort study of urban residents, was established in 1989. We included all participants who were coronary heart disease (CHD) free at baseline. Age (in years) was used as the timescale. Age-specific incidence rates were calculated with the person-year method within 5-year bands. We estimated the sex- and index-age-specific lifetime risk of first-ever CHD, taking the competing risk of death into account. We followed 5834 participants from 1989 to 2007 for a total of 75 387.5 person-years. At age 45 years, the competing risk of death-adjusted lifetime risk for all CHD for men was 14.12% for normotensive men and 26.95% for hypertensive men. The competing risk of death-adjusted lifetime risk for all CHD at 45 years of age for women was 6.21% for normotensive women and 14.85% for hypertensive women. This increased lifetime risk of CHD for hypertensive patients was observed among both men and women across all index ages. Although the overall lifetime risk of CHD was lower than in the Western population, hypertension showed a significant effect on the residual lifetime risk of CHD among Japanese middle-aged men and women. This easy-to-understand knowledge may be used as an important index to assist public health education and planning.

Cardiovascular diseases among patients with schizophrenia.

The presence of comorbid physical illnesses especially, cardiovascular diseases (CVD) in schizophrenia is a growing area of concern in recent years. In order to reduce disease burden, to improve quality of life and to provide holistic care, it is important to know about the relationship between schizophrenia and CVD. The objective of this review is to explore the extent of CVD problems, relevant risk factors and potential measures for early diagnosis and prevention of CVD among patients with schizophrenia. Worldwide studies show that patients with schizophrenia have a higher mortality and lower life expectancy than the general population. CVD is the leading cause of increased mortality in schizophrenia. Common CVD risk factors in schizophrenia include metabolic syndrome, sedentary behaviour, tobacco smoking, effects of antipsychotics, long chain omega-3 fatty acid deficiency and shared genetics between CVD and schizophrenia. The potential methods for early detection and prevention of CVD in schizophrenia are also discussed. Though the patients with schizophrenia form a high risk group for CVD, consensus guidelines for early detection and prevention of CVD in schizophrenia are lacking. Comorbidity of CVD in schizophrenia needs more serious attention by clinicians and researchers.

What is the scope of improving immigrant and ethnic minority healthcare using community navigators: A systematic scoping review.

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.
