The National School Lunch Program (NSLP) provides healthy food to millions of children annually. To promote increased lunch consumption, policy, systems, and environmental (PSE) change strategies are being implemented in child nutrition programs. An evaluation of the current evidence supporting PSE interventions in school nutrition programs is needed to facilitate evidence-based practices across the nation for programs.

Background: The charitable food system distributes free food to clients across the U.S., but many nutrition and health-focused efforts encounter barriers to success, which were exacerbated during the COVID-19 pandemic.

Objective: Efforts to improve the nutritional quality and health promotion in the charitable food system have been undertaken. Though methods exist to track these efforts in terms of food banks' inventory, there are not research-tested tools to assess, monitor and influence policy, systems and environmental (PSE) changes. The study objective was to develop and evaluate a novel assessment tool that could be used to evaluate a food bank's efforts to improve the promotion of health and nutritious foods.

Objective: To evaluate the influence of the Growing Together Illinois fresh produce donation program and understand factors that affect produce distribution at participating food pantries.

Methods: In this intervention at 17 Illinois food pantries, Master Gardeners supported food donation gardens, and Supplemental Nutrition Assistance Program Education provided educational and environmental interventions to increase selection and use of fresh produce. This mixed-methods pre-post study assessed pantry characteristics and program impact via Nutrition Environment Food Pantry Assessment Tool evaluations, interview feedback from pantry staff, and structured pantry observations.

Objective: The objective of the current study was to evaluate the impact of the Market to MyPlate (M2MP) program on participants' reported farmers' market (FM) attitudes and shopping behaviours, frequency of serving vegetables to their families, food resource management behaviours and food security. A secondary objective was to identify facilitators and barriers to shopping at FM and food waste reduction techniques used by low-income families.

Design: The current study used a mixed methods evaluation embedded within a cluster randomised trial of the M2MP intervention.

Background: Eggs are an affordable food providing many shortfall nutrients with the potential to improve cognitive health. We assessed the relationship between whole egg consumption and cognitive functioning among a US nationally representative sample of older adults.

Methods: Individual-level data (2816 adults, aged ≥ 60 years) were obtained from the National Health and Nutrition Examination Survey (NHANES) 2011-2012 and 2013-2014 waves.

Objective: The main objective of this study was to evaluate the impact of the Market to MyPlate (M2MP) program on fruit and vegetable consumption and cooking behaviours. Secondary objectives were to examine factors that affected participant retention and program completion, and analyse program feedback provided by participants.

Design: This study conducted a mixed methods evaluation embedded within a cluster randomised controlled trial of the M2MP intervention.

Background: Improving children's fruit and vegetable (FV) preferences may be important as preferences can predict FV consumption. The purpose of this study was to evaluate FV preferences over time, with repeated experience, as part of the Fresh Fruit and Vegetable Program (FFVP).

Methods: Fruits (F; N = 28) and vegetables (V; N = 29) were distributed twice a week, over 35 weeks, at a participating FFVP school (N = 236 students, 12 teachers, K-2nd grade).

Professional development has been identified as a critical component for school nutrition professionals (SNPs) to successfully implement school meal standards in the United States. However, training needs may vary based on different factors. This study examined (1) the topics of highest priority for SNPs; (2) preferred learning methods; (3) where and when trainings should be conducted; and (4) whether responses differ according to important factors including position type, school locale (urban vs.

Whole-genome mapping technologies have been developed as a complementary tool to provide scaffolds for genome assembly and structural variation analysis (1,2). We recently introduced a novel DNA labeling strategy based on a CRISPR-Cas9 genome editing system, which can target any 20bp sequences. The labeling strategy is specifically useful in targeting repetitive sequences, and sequences not accessible to other labeling methods.

Background: Telomeric DNA is typically comprised of G-rich tandem repeat motifs and maintained by telomerase (Greider CW, Blackburn EH; Cell 51:887-898; 1987). In eukaryotes lacking telomerase, a variety of DNA repair and DNA recombination based pathways for telomere maintenance have evolved in organisms normally dependent upon telomerase for telomere elongation (Webb CJ, Wu Y, Zakian VA; Cold Spring Harb Perspect Biol 5:a012666; 2013); collectively called Alternative Lengthening of Telomeres (ALT) pathways. By measuring (TTAGGG) n tract lengths from the same large DNA molecules that were optically mapped, we simultaneously analyzed telomere length dynamics and subtelomere-linked structural changes at a large number of specific subtelomeric loci in the ALT-positive cell lines U2OS, SK-MEL-2 and Saos-2.

Nudge interventions are widely used to promote health in schools, yet implementation metrics are seldom used to understand intervention outcomes. A multi-component intervention consisting of cafeteria decorations, creative names, social norming taste tests, and flavor station components was implemented in three rural elementary school cafeterias by school nutrition services (SNS) and extension staff. Selection and consumption of fruits and vegetables at lunch were measured through monthly plate waste assessments over eight months ( = 1255 trays).

Sequences encoding Olduvai protein domains (formerly DUF1220) show the greatest human lineage-specific increase in copy number of any coding region in the genome and have been associated, in a dosage-dependent manner, with brain size, cognitive aptitude, autism, and schizophrenia. Tandem intragenic duplications of a three-domain block, termed the Olduvai triplet, in four genes in the chromosomal 1q21.1-0.

There is a need to disseminate evidence-based childhood obesity prevention interventions on a broader scale to reduce obesity-related disparities among underserved children. The purpose of this study was to test the comparative effectiveness of an evidence-based obesity prevention intervention, Hip-Hop to Health (HH), delivered through Expanded Food and Nutrition Education Program (EFNEP) and the Supplemental Nutrition Assistance Program-Education (SNAP-Ed) versus the standard curriculum delivered by the programs (Standard Nutrition Education (NE)). A nonequivalent control group design was delivered to compare the effectiveness of HH to NE on weight gain prevention and health behavior outcomes at EFNEP and SNAP-Ed sites.

Article Synopsis
  • Large structural variants (SVs) in the human genome are typically hard to detect with standard sequencing methods, but long-range genome analysis techniques like optical mapping can effectively identify SVs greater than 2 kb in one go.
  • In a study involving 154 individuals from the 1000 Genomes Project, researchers found that large SV patterns closely match the patterns of single nucleotide variations across 86% of the genome, while about 2% show significant structural complexity.
  • The study also revealed previously uncharacterized regions of the genome, including segmental duplications and areas near chromosomes' ends, identifying roughly 60 Mb of unique genomic content missing from the current reference genome, emphasizing the need for diverse population haplotypes to accurately

Objective: To develop and evaluate a nutrition environment assessment tool to assess the consumer nutrition environment and use of recommended practices in food pantries.

Methods: The Nutrition Environment Food Pantry Assessment Tool (NEFPAT) was developed based on a literature review and guidance from professionals working with food pantries. The tool was pilot-tested at 9 food pantries, an expert panel assessed content validity, and interrater reliability was evaluated by pairs in 3 pantries.
