Abstract
The significant global burden of colorectal cancer accentuates disparities in access to preventive healthcare in most low- and middle-income countries (LMICs) as well as large sections of underserved populations within high-income countries. The barriers to colorectal cancer screening in economically transitioning Latin America are multiple. At the same time, immigration from these countries to the USA continues to increase. This case highlights the delays in diagnosis experienced by a recent immigrant from a country with no established colorectal cancer screening program, to an immigrant population in the USA with similar poor screening coverage. We discuss common challenges faced by Latinos in their home countries and the USA, as well as strategies that could be implemented to improve screening coverage in US immigrant populations.

Abstract
BACKGROUND AND AIMS The prevalence of inflammatory bowel disease (IBD) is increasing globally. In this context, identifying risk factors for severe disease is important. We examined how race/ethnicity and immigration status influence IBD manifestations, treatments, and outcomes in a diverse, tertiary-care safety-net hospital. METHODS We conducted a single-center retrospective review of all IBD inpatients and outpatients treated from 1997-2017. Using logistic regression modeling, we compared disease onset, treatment, and outcomes by race (White, Black, Hispanic, or Asian) and immigration status (US-born vs foreign-born). RESULTS A total of 577 patients were identified, of which 29.8% were White, 27.4% were Hispanic, 21.7% were Black, and 13.0% were Asian. Compared to Whites, Asians were more likely to be male (odds ratio [OR] 2.63, 95% confidence interval [CI]: 1.45, 5.00), whereas Blacks were more likely to be diagnosed with Crohn's disease (OR 1.75, 95% CI: 1.10, 2.77) and more likely to undergo IBD-related intestinal resection (OR 2.49, 95% CI: 1.40, 4.50). Compared to US-born patients, foreign-born patients were more likely to be diagnosed with ulcerative colitis (OR 1.77, 95% CI: 1.04, 3.02). They were also less likely to be diagnosed before 16 years of age (OR 0.19, 95% CI: 0.08, 0.41), to have undergone intestinal resections (OR 0.39, 95% CI: 0.19, 0.83), to have received biologics (OR 0.43, 95% CI: 0.25, 0.76), or to have had dermatologic manifestations (OR 0.12, 95% CI: 0.03, 0.41). CONCLUSION IBD phenotype varies by race, although foreign-born patients of all races show evidence of later-onset and milder disease. These findings may aid in disease prognostication and clinical management and, furthermore, may provide insight into intrinsic and environmental influences on IBD pathogenesis.

Vitamin D and Chronic Diseases among First-Generation Immigrants: A Large-Scale Study Using Canadian Health Measures Survey (CHMS) Data. Nutrients 2022; 14:nu14091760. [PMID: 35565728 PMCID: PMC9099619 DOI: 10.3390/nu14091760] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2022] [Revised: 04/13/2022] [Accepted: 04/18/2022] [Indexed: 02/04/2023] Open
Abstract
Background: Nearly 22% of the Canadian population are first-generation immigrants. We investigated immigrants’ health status and health deterioration over time in terms of the prevalence of chronic diseases (CDs) and their relationship to vitD status. Methods: We used cycles three (2012–2013) and four (2014–2015) of the Canadian Health Measures Survey. These data contained unique health information and direct physical/blood measures, including serum 25-hydroxyvitamin D (S-25(OH)D). Indicators of health status and deterioration were the prevalence of CDs diagnosed by healthcare professionals, self-reported general and mental health, and CD-related biomarkers. Results: The data (n = 11,579) included immigrants from more than 153 countries. Immigrants were healthier than non-immigrants for most health status measures. The prevalence of CDs was higher among those who migrated to Canada aged ≥ 18 years. A longer time in Canada after immigration was associated with a higher risk for CDs. The mean S-25(OH)D was lower among immigrants, higher among patients with CDs, and inversely associated with glycated hemoglobin, total cholesterol/high-density lipoprotein ratio, immunoglobulin E, serum ferritin, and blood hemoglobin. After adjusting for covariates, no association was found between S-25(OH)D and the prevalence of CDs. Conclusions: Lower levels of accumulated S-25(OH)D among immigrants may impact their health profile in terms of CD-related biomarkers, which partially explains immigrants’ health deterioration over time. We recommend further longitudinal research to investigate immigrants’ vitD and health deterioration.

Abstract
BACKGROUND Colorectal cancer (CRC) is the second most common cause of cancer death in Canada. Immigrants in Ontario, Canada's most populous province, are known to have lower rates of CRC screening, but differences in stage of CRC diagnosis are not known. METHODS We utilized linked administrative databases to compare early (stage I-II) versus late (stage III-IV) stage of CRC diagnosis for immigrants versus long-term residents among patients diagnosed in Ontario between 2012 and 2017 (n = 37,717) and examined the association of immigration-related, sociodemographic, and healthcare-related factors with stage. RESULTS Almost 45% of those with CRC were diagnosed at a late stage. Immigrants were slightly more likely to be diagnosed at a late stage than their long-term resident counterparts [Adjusted relative risks (ARRs) 1.06 (95% CI 1.02-1.10)], but after adjusting for age and sex, this difference was no longer significant. In fully adjusted models, we observed a higher likelihood of late-stage diagnosis for people with the fewest co-morbidities (ARR 0.86 [95% CI 0.83-0.89]) and those with no visits to primary care (versus a high level of continuity of care) [ARR 1.07 (95% CI 1.03-1.12)]. CONCLUSION Immigrants were not more likely to have a late-stage CRC diagnosis after adjusting for relevant factors, but access to primary care and healthcare contact was significantly associated with diagnostic stage. IMPACT Attachment to a primary care provider who provides regular preventive care may play a role in more favorable stage at diagnosis for CRC and thus should be a healthcare system priority.

Abstract
OBJECTIVES To evaluate the association between immigration status and all-cause mortality in different disease cohorts, and the impact of loss to follow-up on the observed associations. DESIGN Population-based retrospective cohort study using linked administrative health data in Ontario, Canada. SETTING We followed adults with a first-ever diagnosis of ischaemic stroke, cancer or schizophrenia between 2002 and 2013 from index event to death, loss to follow-up, or end of follow-up in 2018. PRIMARY AND SECONDARY OUTCOME MEASURES Our outcomes of interest were all-cause mortality and loss to follow-up. For each disease cohort, we calculated adjusted HRs of death in immigrants compared with long-term residents, adjusting for demographic characteristics and comorbidities, with and without censoring for those who were lost to follow-up. We calculated the ratio of two the HRs and the respective CL using bootstrapping methods. RESULTS Immigrants were more likely to be lost to follow-up than long-term residents in all disease cohorts. Not accounting for this loss to follow-up overestimated the magnitude of the association between immigration status and mortality in those with ischaemic stroke (HR of death before vs after accounting for censoring: 0.78 vs 0.83, ratio=0.95; 95% CL 0.93 to 0.97), cancer (0.74 vs 0.78, ratio=0.96; 0.95 to 0.96), and schizophrenia (0.54 vs 0.56, ratio=0.97; 0.96 to 0.98). CONCLUSIONS Immigrants to Canada have a survival advantage that varies by the disease studied. The magnitude of this advantage is modestly overestimated by not accounting for the higher loss to follow-up in immigrants.

Abstract
BACKGROUND AND OBJECTIVES To evaluate the association between immigration status and stroke incidence. METHODS We conducted a retrospective cohort study of 8 million adults (15% immigrants) residing in Ontario, Canada, on January 1, 2003, with no history of stroke or TIA. Participants were followed up until March 31, 2018, to identify incident stroke or TIA, defined as hospitalization or emergency room visit. We calculated adjusted hazard ratios (HRs) of stroke or TIA in immigrants compared to long-term residents using cause-specific hazard models, adjusting for demographics and comorbid conditions. We evaluated whether the association varied by age, stroke type, or country of origin of immigrants. RESULTS During 109 million person-years of follow-up, we observed 235,336 incident stroke or TIA events. Compared to long-term residents, immigrants had a lower rate of stroke or TIA (10.9 vs 23.4 per 10,000 person-years, HR 0.67, 95% confidence interval [CI] 0.66-0.68). This was true across all age groups and stroke types, with an HR in immigrants vs long-term residents for ischemic stroke of 0.71 (95% CI 0.69-0.72), for intracerebral hemorrhage of 0.89 (95% CI 0.85-0.93), for subarachnoid hemorrhage of 0.85 (95% CI 0.81-0.91), and for TIA of 0.53 (95% CI 0.51-0.54). The magnitude of the reduction in stroke risk associated with immigration status was less pronounced in immigrants from the Caribbean (HR 0.95, 95% CI 0.91-1.00), Latin America (HR 0.85, 95% CI 0.82-0.91), and Africa (HR 0.80, 95% CI 0.74-0.85) than in those from other world regions. DISCUSSION Immigrants have a lower rate of stroke or TIA than long-term residents with variation by age, stroke type, and country of origin. This knowledge may be useful for developing targeted primary stroke prevention strategies.

Abstract
Gastric cancer is the 5th most common malignancy worldwide, representing ~5–10% of all new cancer cases. Although its incidence is declining, it is estimated that 1 in 98 Canadians will develop gastric cancer in their lifetime. The epidemiology and distribution of gastric cancer throughout Canada, however, remains poorly understood. A retrospective analysis of demographic data across Canada between 1992 and 2010 was performed using 2 population-based cancer registries. The incidence of gastric cancer was examined at the levels of provinces, cities, and postal codes. In addition, 43,955 patients were diagnosed with gastric cancer in Canada between 1992 and 2010; 66% were male and the average age of diagnosis was 68.4 years. The age-adjusted incidence rate was 5.07 cases per 100,000 individuals per year. The incidence decreased over the study period by 30%. High incidence rates were identified in rural areas of Newfoundland and Labrador, New Brunswick, and Quebec. Our study found a significant association between gastric cancer incidence rates and lower socioeconomic status, as well as Hispanic ethnicity. This is the first study to provide a comprehensive analysis of the incidence of gastric carcinoma in Canada, identifying high-risk populations that may benefit from increased primary and secondary prevention.

Abstract
The rate of cancer screening is generally increasing in the US. In Minnesota, the statewide average rate of screening for colorectal cancer (CRC) is 73%. However, screening completion is relatively low among Somali men; overall, only 27% of Somali immigrants have been screened for CRC. Factors contributing to this disparity have not been well researched. The purpose of this pilot study was to employ focus group methodology to describe and advance understanding of the barriers and enablers associated with CRC screening among Somali men ages 50-74 in Minnesota. Three focus groups were conducted among 27 Somali men in Minnesota. A 9-question, semi-structured interview guide was used. The sessions were audio recorded, transcribed verbatim, and checked for accuracy by research staff prior to data analysis. Three research team members utilized the constant comparative method and NVivo to conduct data analysis. Five barriers to CRC screening emerged from the analyses: (1) lack of knowledge, (2) emotional barriers, (3) acculturation, (4) accountability, and (5) fatalistic beliefs. In addition, two factors enabling CRC screening and prevention emerged: the need for tailored interventions and preventive lifestyle behaviors. The insights gained from this research will assist in developing health promotion and education-focused interventions that encourage Somali immigrants in Minnesota and beyond to seek early detection screening for CRC.Abbreviations: CRC: Colorectal Cancer; FIT: Fecal Immunochemical Test; FOBT: Fecal Occult Blood Test; FQHC: Federally Qualified Health Center; PA: Project Assistant; PI: Principal Investigator.

BACKGROUND Several social determinants of health have been examined in relation to colorectal cancer incidence, stage at diagnosis, and survival including income, education, neighborhood disadvantage, immigration status, social support, and social network. Colorectal cancer incidence rates are positively associated with income and other measures of socioeconomic status. In contrast, low socioeconomic status tends to be associated with poorer survival. METHODS The present review is based upon bibliographic searches in PubMed and CINAHL and relevant search terms. Articles published in English from 1970 through April 1, 2019 were identified using the following MeSH search terms and Boolean algebra commands: colorectal cancer AND (incidence OR stage OR mortality) AND (social determinants OR neighborhood disadvantage OR racial discrimination OR immigration OR social support). RESULTS This review indicates that poverty, lack of education, immigration status, lack of social support, and social isolation play important roles in colorectal cancer stage at diagnosis and survival. CONCLUSIONS To address social determinants of colorectal cancer, effective interventions are needed that account for the social contexts in which patients live.

Abstract
The present study was conducted to determine the prognostic significance of I655V SNP (rs1136201) is a genetic one in HER-2 oncoprotein in cases of colorectal cancer (CRC). We conducted a case-control study analysing 83 subjects (naïve primary CRC cases) who underwent CRC biopsy/colectomy and included 57 healthy control subjects. Analysis of HER-2 polymorphism was done by PCR-RFLP technique. The mean age was found to be 55.9 years; median age was 56 years and mode age was 54 years with a range of 43 (30-73). Males constitute 63 (75.9%) and females constitute 20 (24.1%) of patient population. According to gradewise distribution, 12 (14.45%) patients were of Grade I, 53 (63.85%) of Grade II, and 18 (21.68%) were of Grade III. We found out that out of 83 patients, 52 (62.65%) were of homozygous wild type (A/A; Ile/Ile); 27 (32.53%) were of heterozygous type (A/G; Ile/Val) and 4 (4.81%) were of homozygous mutant type (G/G; Val/Val). Allelic frequency of Ile (A) was found out to be 0.79 and that of Val (G) is 0.21 and were not significantly different from the healthy control population. Fischer's exact p value obtained was 0.86.

Rates of Prevalent Colorectal Cancer Occurrence in Persons 75 Years of Age and Older: A Population-Based National Study. Dig Dis Sci 2018; 63:1929-1936.

Abstract
BACKGROUND/AIMS There is a lack of studies describing the epidemiology of colorectal cancer (CRC) in patients aged 75 years and older (elderly). Current guidelines recommend against routine screening colonoscopies in this population. We sought to describe the epidemiology of CRC in the elderly, utilizing a large, population-based database as this may impact screening guidelines in this population. METHODS Utilizing a commercial database (Explorys Inc, Cleveland, OH), we identified a cohort of patients with a first-ever diagnosis of CRC between 2012 and 2017 based on the Systematized Nomenclature of Medicine-Clinical Terms. We calculated the rate of first-ever CRC occurrence in the elderly, described age, race, and gender-based rates of new CRC diagnoses, and identified associated conditions for new CRC in the elderly. RESULTS The rate of first-ever CRC in the elderly (aged 75 and above) was 102.6/100,000 persons. The rate of new CRC was higher in males than females and in African Americans than Caucasians and Asians. There was a higher prevalence of right than left colon cancer. The rate of new CRC was higher in elderly with certain comorbidities. CONCLUSION The rate of new CRC diagnosis in the elderly was substantially greater compared to the overall population. Screening would be justified especially if a patient's life expectancy warrants it particularly if the patient has specific associated conditions that increase the risk for CRC.
