Objective: To simulate the effect of child-friendly (CF) adaptations of the National Cancer Institute's Automated Self-Administered 24-Hour Dietary Recall (ASA24) on estimates of nutrient intake.
Method: One hundred twenty children, 8-13 years old, entered their previous day's intake using the ASA24 and completed an interviewer-administered recall using the Nutrition Data System for Research (NDSR). Based on a hypothesis that proposed adaptations to the ASA24 will not significantly affect mean nutrient estimates, ASA24 data were manipulated postadministration to simulate a CF version in which 2 categories of data collection were removed: (1) foods not likely to be consumed by children (45%) based on previous analyses of national dietary data and (2) food detail questions (probes) to which children are unlikely to know the answers (46%), based on our experience.
Results: Mean estimates of select nutrients between the beta version of ASA24 and the simulated CF recall showed no significant differences, indicating that the food and probe elimination did not significantly affect results. However, a comparison of total sugar and vitamin C assessments between the original ASA24, the CF version, and NDSR showed that the daily nutrient totals for both nutrients were significantly higher in the self-administered methods (both ASA24 and CF version) than in NDSR (interviewer-administered), which warrants a review of different methods for obtaining information about foods that are sources of these nutrients.
Conclusion: The simulation of CF adaptations showed that it is feasible to implement, thereby reducing CF response burden without significantly affecting the results.

Estimating Total-Tract Digestibility of Nutrients and Their Contribution to Digestible Energy Supplies in Equine Diets.

Our objectives were to use a quantitative literature review to explore dietary and feed factors influencing apparent total-tract digestibility of dry matter (DMD), crude protein (CPD), neutral detergent fiber (NDFD), ether extract (EED), non-structural carbohydrates (NSCD), non-fiber carbohydrates (NFCD), and residual organic matter (rOMD) in equine diets, and to assess their contributions to digestible energy (DE) supplies. Data from 54 studies were modeled using linear mixed-effect regressions, with publication as a random effect to account for study variability. For each nutrient, five models were derived with explanatory variables including: dry matter intake (DMI; % BW/day) and DM (% as-fed), and dietary components (CP, organic matter, EE, NDF, acid detergent fiber, NSC, starch, and NFC as % of DM), and feed types (forage, non-forage fiber, legumes, cereal, and oil proportions).

Freeze-drying fresh vegetables and fruits may not only prevent post-harvest losses but also provide a concentrated source of nutrients and phytochemicals. This study focused on the phenolic composition of different freeze-dried products derived from horticultural crop remains (HCRs) in the vegetable and fruit production chain. These products may be considered as a potential health-promoting solution for preventing post-harvest fruit spoiling and losses.

Background/objectives: The DNA methylation of neonatal cord blood can be used to accurately estimate gestational age. This is known as epigenetic gestational age. The greater the difference between epigenetic and chronological gestational age, the greater the association with an inappropriate perinatal fetal environment and development.
