Pancreatic Cancer Following Incident Diabetes in African Americans and Latinos: The Multiethnic Cohort.

ABSTRACT: Background:Diabetes has been proposed to be a risk factor for and a consequence of pancreatic cancer (PC). The relationship between recent-onset diabetes and PC is not well understood, and data in minorities are sparse. We examined the relationships between recent-onset diabetes and PC incidence in African Americans and Latinos in the Multiethnic Cohort. Methods:A total of 48 995 African Americans and Latinos without prior diabetes and cancer at baseline (1993-1996) were included in the study. Questionnaires, Medicare data, and California hospital discharge files were used to identify new diabetes diagnoses. Cox regressions were used to calculate hazard ratios (HRs) and 95% confidence intervals (CIs) for cancer associated with diabetes and with diabetes duration. Results:A total of 15 833 (32.3%) participants developed diabetes between baseline and 2013. A total of 408 incident PC cases were identified during follow-up. Diabetes was associated with PC (HRage75 = 2.39, 95% CI = 1.91 to 2.98). Individuals with recent-onset diabetes (within three or fewer years of PC diagnosis) had a greater risk compared with those with long-term diabetes across all ages. The HRage75 for recent-onset diabetes was 4.08 (95% CI = 2.76 to 6.03) in Latinos and 3.38 (95% CI = 2.30 to 4.98) in African Americans. Conclusions:Diabetes was associated with a more than twofold higher risk of PC in African Americans and Latinos, but recent-onset diabetes was associated with a 2.3-fold greater increase in risk of PC than long-standing diabetes. Our findings support the hypothesis that recent-onset diabetes is a manifestation of PC and that long-standing diabetes is a risk factor for this malignancy.

Project description:Purpose:Diabetes self-management education and support (DSME/S) is an effective strategy to improve health outcomes. However, little is known about the impact of formal DSME/S on psychological distress among minority populations. The study purposes were to 1) explore the impact of a culturally tailored DSME/S intervention on psychological distress and diabetes-related outcomes among African-American and Hispanic/Latino participants and 2) examine differences across groups in self-care, self-efficacy, diabetes knowledge, and psychological distress. Methods:Using a pre- and post-test research design, baseline and post-test assessments were conducted at weeks 1 and 7 of the intervention, respectively. Statistical analyses included descriptive statistics for demographic variables and four outcomes (self-care, self-efficacy, knowledge, and psychological distress score), general linear regression analysis of the post-test outcomes, and the Spearman correlation between psychological distress score and the outcomes. Results:Compared to African-American participants (n = 122), Hispanic/Latino participants (n = 137) were significantly younger and less educated. The two groups were comparable in sex, income, and health status. Significant pre- to post-test improvements were seen in each group for self-care, self-efficacy, and psychological distress. Diabetes knowledge had moderate improvement. Hispanics/Latinos had significantly greater post-test self-efficacy and self-care scores compared to African Americans. For both African-American and Hispanic/Latino participants, lower psychological distress scores were generally associated with greater self-efficacy and self-care. Psychological distress scores were not significantly associated with knowledge in African-Amerian or Hispanic/Latino participants. For African Americans only, better health status was significantly associated with less psychological distress. Conclusion:DSME/S programs have the potential to improve psychological health among African Americans and Hispanics/Latinos, which can lead to better diabetes outcomes.

Project description:Novel biomarkers that more accurately reflect kidney function and predict future CKD are needed. The human metabolome is the product of multiple physiologic or pathophysiologic processes and may provide novel insight into disease etiology and progression. This study investigated whether estimated kidney function would be associated with multiple metabolites and whether selected metabolomic factors would be independent risk factors for incident CKD.In total, 1921 African Americans free of CKD with a median of 19.6 years follow-up among the Atherosclerosis Risk in Communities Study were included. A total of 204 serum metabolites quantified by untargeted gas chromatography-mass spectrometry and liquid chromatography-mass spectrometry was analyzed by both linear regression for the cross-sectional associations with eGFR (specified by the Chronic Kidney Disease Epidemiology Collaboration equation) and Cox proportional hazards model for the longitudinal associations with incident CKD.Forty named and 34 unnamed metabolites were found to be associated with eGFR specified by the Chronic Kidney Disease Epidemiology Collaboration equation with creatine and 3-indoxyl sulfate showing the strongest positive (2.8 ml/min per 1.73 m(2) per +1 SD; 95% confidence interval, 2.1 to 3.5) and negative association (-14.2 ml/min per 1.73 m(2) per +1 SD; 95% confidence interval, -17.0 to -11.3), respectively. Two hundred four incident CKD events with a median follow-up time of 19.6 years were included in the survival analyses. Higher levels of 5-oxoproline (hazard ratio, 0.70; 95% confidence interval, 0.60 to 0.82) and 1,5-anhydroglucitol (hazard ratio, 0.68; 95% confidence interval, 0.58 to 0.80) were significantly related to lower risk of incident CKD, and the associations did not appreciably change when mutually adjusted.These data identify a large number of metabolites associated with kidney function as well as two metabolites that are candidate risk factors for CKD and may provide new insights into CKD biomarker identification.
