Inflammation plays a key role in cancer development. As an important modulator of inflammation, the role of diet should be explored. The purpose of this study was to determine the association between diets with a higher inflammatory potential, as measured by the Dietary Inflammatory Index (DII®), and cancer development in a cohort of rural post-menopausal women. Dietary intake from a randomized controlled trial cohort of rural, post-menopausal women in Nebraska was used to compute energy-adjusted DII (E-DIITM) scores at baseline and four years later (visit 9). A linear mixed model analysis and multivariate logistic regression evaluated the association between E-DII scores (baseline, visit 9, change score) and cancer status. Of 1977 eligible participants, those who developed cancer (n = 91, 4.6%) had a significantly larger, pro-inflammatory change in E-DII scores (Non-cancer: Δ 0.19 ± 1.43 vs. Cancer: Δ 0.55 ± 1.43, p = 0.02). After adjustment, odds of cancer development were over 20% higher in those with a larger change (more pro-inflammatory) in E-DII scores than those with smaller E-DII changes (OR = 1.21, 95% CI [1.02, 1.42], p = 0.02). Shifting to a more pro-inflammatory diet pattern over four years was associated with increased odds of cancer development, but not with E-DII at baseline or visit 9 alone.

Background/Objectives: Refeeding syndrome (RFS) is challenging to prevent and manage in hospitalized patients receiving enteral nutrition (EN). Nebraska Medicine implemented an Electronic Medical Record (EMR) Refeeding Risk Order Set (RROS) to standardize prevention measures, including structured electrolyte monitoring, thiamine supplementation, and conservative EN initiation. This study evaluated whether RROS implementation reduced RFS occurrence or severity and assessed its operational impact. Methods: In this retrospective cohort study, adults receiving EN before and after RROS implementation were compared. Primary outcomes were RFS occurrence and severity; secondary outcomes included EN initiation and advancement rates, electrolyte trends, lab frequency, and electrolyte repletion. Results: RFS occurrence did not differ significantly between groups (92.3% vs. 91.3%, p = 0.694), nor did severity (p = 0.535). The post-RROS group received more electrolyte boluses on EN Day 0 (p = 0.027) and had a lower EN starting rate (15.7 vs. 18.3 mL/h, p = 0.045). Conclusions: Although the RROS did not reduce RFS occurrence or severity, integrating American Society for Parenteral and Enteral Nutrition (ASPEN)-based guidance into the EMR was highly feasible and adopted immediately. Automating electrolyte monitoring, micronutrient supplementation, and conservative feeding initiation reduces the risk of errors and promotes consistent care. These benefits improve workflow efficiency and support providers during high census periods, limited staffing, or when experience varies. Future research should explore combining EMR tools with predictive analytics to optimize early risk identification and individualized management.
