Background: This paper describes the impact of the Eat Smart School Nutrition Program, the food service component of the Child and Adolescent Trial for Cardiovascular Health (CATCH), on the percentage of calories from total fat and saturated fat and the sodium content of school breakfasts.
Methods: Fifty-nine of the 96 CATCH schools offered breakfast. We collected 5 consecutive days of school breakfast menu, recipe, and vendor product information at three periods to assess the nutrient content of the school menus as offered.
Results: At baseline (Fall 1991), intervention school breakfasts provided 28% of calories from total fat and control schools 30%. Decreases occurred over time in both groups, but no significant differences were attributable to the intervention (adjusted mean difference = -0.4; P = 0.77). Saturated fat exceeded the Eat Smart goal at baseline in all schools and by follow-up (Spring 1994), the reduction in mean percentage of calories from saturated fat was greater in intervention than in control schools (adjusted mean difference = -1.6%; P = 0.052). Sodium goals were not achieved. Mean calorie levels were maintained at or above Eat Smart goals throughout the study in both groups. Differences over time in other dietary variables (percentage of calories from protein and carbohydrate and mean levels of protein, carbohydrate, calcium, iron, vitamin A value, vitamin C, total sugars, and dietary fiber) were not statistically significant between groups. No significant reductions in student participation in the School Breakfast Program (SBP) occurred.
Conclusions: The Eat Smart food service intervention improved school breakfast composition, but not significantly more so than in control schools. Fat and saturated fat in school breakfasts were lowered while maintaining calories, other essential nutrient levels, and student participation in the SBP. Secular trends and also the possibility that control schools were affected by the Eat Smart intervention may account for these findings.

Adoptive transfer of genetically or nanoparticle-engineered macrophages represents a promising cell therapy modality for treatment of solid tumor. However, the therapeutic efficacy is suboptimal without achieving a complete tumor regression, and the underlying mechanism remains elusive. Here, we discover a subpopulation of cancer cells with upregulated CD133 and programmed death-ligand 1 in mouse melanoma, resistant to the phagocytosis by the transferred macrophages.

Purpose: To evaluate the efficacy of Your Move, a multisession blended learning sexual health education program for females aged 14-19 years.
Methods: This group randomized controlled trial included a sample of 104 groups comprised of 808 females aged 14-19 years. After completing the baseline survey, small groups of 4-16 participants were randomized, stratified by 6 regions, to receive Your Move (n = 58 groups, 412 participants) or an attention control program called Eat Smart (n = 46 groups, 396 participants).

Background/objectives: Improved global data allow for a new understanding of what impact the food we produce, eat and dispose of has on the environment, human health and Nature's resources. The overall goal is to guide decision-makers and individuals by providing in-depth knowledge about the effects of their dietary preferences on human and environmental health.
Methods: The method is to investigate ways to reduce environmental degradation and to secure healthy food supplies in an urbanizing world, and to quantify the options.

Background: Individuals with higher weight (overweight or obesity) may experience social stigma due to their weight. Weight stigma can be internalized with adverse health effects. Internalized weight stigma is relevant across different weight categories, but no validated weight-neutral measure of internalized weight bias currently exists in Norway.
