Randomized Controlled Trial Clinical TrialDietary change in an intervention trial of wheat bran fiber and colorectal adenoma recurrence.
The objectives of this study were to determine whether participants in the Wheat Bran Fiber (WBF) trial exhibited changes in diet over time, and whether these changes were differential by assigned treatment group. ⋯ Although differential dietary intake was not appreciable in the WBF trial, participants exhibited longitudinal changes. Future intervention studies should carefully monitor dietary changes during the trial with multiple dietary assessment tools to assess potential secular and treatment-related diet changes.

Comparative StudyRacial disparity in pregnancy-related mortality following a live birth outcome.
African-American women have a 2- to 4-fold increased risk of pregnancy-related death compared with Caucasian women. We conducted this study to determine if differences in a combination of socioeconomic and medical risk factors may explain this racial disparity in pregnancy-related death. ⋯ Our analysis confirms that there is a strong association between race and pregnancy-related death, even after adjusting for potential predictors and confounders.
