The authors investigated whether red blood cell distribution width (RDW) was associated with the development of cardiovasculardisease (CVD) events and mortality in a community cohort in Taiwan. The influence of anemia on the association was also assessed. RDW levels were measured in 3,226 participants aged 35 years or older who reported no CVD or cancer at baseline in 1990. During a median follow-up period of 15.9 years (1990-2007), 358 participants experienced stroke and/or coronary heart disease, and 810 participants died. The multivariate-adjusted hazard ratio for subjects in the highest RDW quartile as compared with the lowest quartile was 1.46 for both all-cause mortality (95% confidence interval: 1.17, 1.81) and non-CVD mortality (95% confidence interval: 1.13, 1.88) (P for trend < 0.01 for both) but was not significant for CVD morbidity and mortality. Further analyses showed that in comparison with participants with low RDW and no anemia, persons with high RDW but no anemia had elevated risks of all-cause mortality and non-CVD mortality. The authors conclude that elevated RDW values are associated with increased risk of mortality but not the development of CVD in the general population. RDW may precede anemia in predicting the risk of non-CVD death.

OBJECTIVE
We prospectively assessed the age- and sex-specific incidence and relative risk of malignant neoplasm of the pancreas in Taiwan’s diabetic population.
RESEARCH DESIGN AND METHODS
A total of 615,532 diabetic patients and 614,871 age- and sex-matched control subjects were linked to inpatient claims (2000–2006) to identify the admissions for malignant neoplasm of the pancreas (ICD-9: 157). The Cox proportional hazards regression model was used to estimate the age- and sex-specific relative risk of pancreatic neoplasm.
RESULTS
Compared with the control group, the diabetic patients had a significantly increased risk of pancreatic cancer (hazard ratio [HR] 1.54 [95% CI 1.39–1.71]). The higher and significant age-specific HRs were observed in diabetic men (1.91) and women (1.80) aged 45–65 years.
CONCLUSIONS
Middle-aged diabetic men and women were associated with the most increased risk of malignant neoplasm of the pancreas.
