NEFPAT Plus: A Valid and Reliable Tool for Assessing the Nutrition Environment in Food Pantries. JOURNAL OF NUTRITION EDUCATION AND BEHAVIOR 2024:S1499-4046(24)00028-9. [PMID: 38520424 DOI: 10.1016/j.jneb.2024.02.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/22/2023] [Revised: 01/23/2024] [Accepted: 02/21/2024] [Indexed: 03/25/2024]
Abstract
OBJECTIVE To develop a consumer nutrition environment assessment tool to assess policy, systems, and environmental initiatives that are implemented in food pantries, which incorporates recent national guidance, and evaluate its validity and reliability. SETTING Illinois, US. DESIGN This study had 4 phases: (1) tool revision, (2) pilot testing, (3) content validity assessment, and (4) interrater and test-retest reliability assessment. The original Nutrition Environment Food Pantry Assessment Tool (NEFPAT) was revised to incorporate evidence from updated guidelines and evidence. The NEFPAT+ was pilot-tested by 9 professionals at 5 food pantries. After revisions, 18 experts rated the content validity. Interrater and test-retest reliability was based on 2-4 professionals completing independent evaluations at 21 food pantries twice, 1 month apart. ANALYSIS Content validity indices and intraclass correlation (ICC) coefficients for reliability estimates were compared with established thresholds. RESULTS The NEFPAT+ was rated content valid by 94% of experts. The ICC for NEFPAT+ scores indicated excellent interrater reliability (ICC, 0.96; 99% confidence interval, 0.75-0.97) and good test-retest reliability (ICC: 0.80; 99% confidence interval, 0.60-0.92). CONCLUSIONS Evidence supports the content validity, interrater reliability, and test-retest reliability of the NEFPAT+. Future studies can assess how NEFPAT+ scores relate to intervention outcomes and dietary behaviors.

Policy, Systems, and Environmental Changes in Child Nutrition Programs: A Systematic Literature Review. Adv Nutr 2024; 15:100116. [PMID: 37716534 PMCID: PMC10700153 DOI: 10.1016/j.advnut.2023.09.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2022] [Revised: 09/06/2023] [Accepted: 09/13/2023] [Indexed: 09/18/2023] Open
Abstract
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. This systematic review aims to determine the quality and breadth of available evidence of the effectiveness of PSE strategies on the consumption and waste of fruits, vegetables, milk, and water in the NSLP. The inclusion criteria required studies to occur in a United States K-12 school setting, data collection after 2012, report consumption and waste findings for fruit, vegetable, milk, or water, and be an original research article. Articles included in the review are restricted to positive or neutral quality. Thirty studies are included, policy level (n = 4), systems level (n = 8), environmental level (n = 10), and multi-category (n = 8). Results from positively rated policy-level studies suggest that recess before lunch may increase milk consumption, whereas removing flavored milk may decrease consumption. System-level studies of offering vegetables first in isolation of other meal components and offering spiced vegetables compared with traditional preparations may increase vegetable consumption, and locally procuring produce may increase fruit and vegetable consumption. Environmental-level studies such as water promotion strategies such as placing cups near drinking fountains may increase water consumption. Improving the convenience, attractiveness, and palatability of fruits and vegetables may increase consumption. Future PSE research in child nutrition programs should incorporate implementation aides and metrics into their study designs to allow a better understanding of how to sustain interventions from the perspective of school nutrition professionals.

Distribution of fresh foods in food pantries: challenges and opportunities in Illinois during the COVID-19 pandemic. BMC Public Health 2023; 23:1307. [PMID: 37420188 PMCID: PMC10327385 DOI: 10.1186/s12889-023-16215-4] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2023] [Accepted: 06/29/2023] [Indexed: 07/09/2023] Open
Abstract
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. The objective of the current study was to understand barriers and facilitators to distributing nutritious, fresh foods in food pantries across Illinois during the COVID-19 pandemic. METHODS Forty-nine pantry representatives participated in focus groups in October 2021. A codebook was created based on relevant literature, stakeholder interests, and an initial review of the recordings. Transcripts of each group were coded and analyzed using a basic interpretive approach. RESULTS Pantries distribution of fresh foods was impacted by community partners, food bank policies and practices, and the quality of the donated fresh foods. Physical constraints of pantries limit fresh food storage capacity. The COVID-19 pandemic magnified stressors in the charitable food system which highlighted how community partners might improve fresh food distribution. CONCLUSION Focus groups with food pantry representatives across Illinois provided key insights that can inform future efforts to facilitate fresh food distribution in the charitable food system. Future studies should evaluate the effects of the suggested initiatives and changes at the food pantry, food bank, and policy levels.

Development and evaluation of the Food Bank Health and Nutrition Assessment. Public Health Nutr 2023; 26:1-10. [PMID: 36710006 PMCID: PMC10131141 DOI: 10.1017/s1368980023000204] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2022] [Revised: 12/09/2022] [Accepted: 01/02/2023] [Indexed: 01/31/2023]
Abstract
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. DESIGN The study had five phases: (1) initial development; (2) iterative review and revisions; (3) pilot testing; (4) content validity assessment and (5) inter-rater and test-retest assessment. The Food Bank Health and Nutrition Assessment (FB-HANA) was drafted after reviewing existing policies, nutrition-focused charitable food systems guidance and similar tools for food pantries. SETTING Midwestern United States. PARTICIPANTS Eleven food banks. RESULTS Stakeholders and pilot testers provided initial feedback to refine the FB-HANA's flow, ease of completion and collection of contextual information. External experts rated the FB-HANA and each of the eight objectives as content valid. A set of two assessments completed by twenty-six community-based professionals, employed by Extension and fourteen food bank staff across eleven food banks, supported moderate to excellent inter-rater and test-retest reliability for the FB-HANA overall and each of its objectives. CONCLUSIONS Evidence suggests that the FB-HANA can be used by either food bank or community-based professionals, such as Extension staff, to provide a perspective on ways food banks promote health and nutrition through PSE approaches.

Nutrition Environment at Food Pantries Improves After Fresh Produce Donation Program. JOURNAL OF NUTRITION EDUCATION AND BEHAVIOR 2022; 54:432-441. [PMID: 35534101 DOI: 10.1016/j.jneb.2021.09.005] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/20/2021] [Revised: 09/11/2021] [Accepted: 09/16/2021] [Indexed: 06/14/2023]
Abstract
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. RESULTS Pantries experienced significant increases from preintervention to postintervention in providing various types of produce, marketing and nudging healthful products, providing additional resources, and total Nutrition Environment Food Pantry Assessment Tool scores. Participants had positive feedback about the program and educational interventions and reported the weekly timing of donations mitigated potential storage and spoilage issues. CONCLUSIONS AND IMPLICATIONS Future research could focus on approaches to increase fresh produce in food pantries while supporting clients via nutrition and cooking education.

Abstract
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. Cognitive assessments included the Consortium to Establish a Registry for Alzheimer's Disease Word List Learning Test (CERAD-WL), Word List Recall Test (CERAD-DR), Animal Fluency Test (AF) and Digit Symbol Substitution Test (DSST). A composite cognitive z-score was constructed based on the individual tests to represent one's overall cognitive functioning. Multiple linear and logistic regressions were performed to examine the effect of whole egg consumption on cognitive functioning, adjusting for individual characteristics and survey design. RESULTS Approximately 57% of older adults consumed whole eggs, with an average daily intake of 34 g of whole egg equivalent among consumers. The average z-scores of the CERAD-WL, CERAD-DR, AF and DSST tests were -0.08, 0.23, 0.37 and 0.42, respectively, and the overall composite cognitive z-score was 0.24 among older adults. Regression analyses found that neither whole egg consumption status, nor daily intake quantity was associated with cognitive test scores. CONCLUSIONS No association was found between whole egg consumption and cognitive functioning among US older adults. Study limitations included cross-sectional study design and measurement errors. Future studies with longitudinal or experimental design are warranted to examine the possible link between egg consumption and cognition in older adults.

Abstract
OBJECTIVE To assess changes in food pantries' consumer nutrition environment (CNE) after the provision of technical assistance. DESIGN Pre-post study with 2 phases. SETTING Staff completed observational assessments using the Nutrition Environment Food Pantry Assessment Tool (NEFPAT) at food pantries in an initial pilot phase. Then, staff conducted NEFPAT observations at pantries in Illinois statewide. PARTICIPANTS In the pilot phase, 6 staff assessed 28 pantries. In the statewide phase, 35 staff assessed 119 pantries. INTERVENTION After completing an initial NEFPAT at each pantry, technical assistance was provided by staff to support changes in the pantries' CNE before another NEFPAT observation was completed. MAIN OUTCOME MEASURE Changes in the CNE, as assessed with the NEFPAT, when comparing preassessment and postassessment. ANALYSIS Score differences were evaluated with paired t tests. RESULTS In the pilot phase, among 23 pantries with preassessment and postassessment data, 2 objectives on the NEFPAT observation increased significantly. In the statewide phase, among 66 pantries with preassessment and postassessment data, most NEFPAT objectives and the overall NEFPAT score (22.12 ± 8.16 vs 28.20 ± 7.14, P < 0.001) significantly increased. CONCLUSIONS AND IMPLICATIONS Technical assistance provided by Supplemental Nutrition Assistance Program Education implementing staff were related to improvements in the CNE of food pantries in Illinois. Future work should evaluate the association of these CNE changes with changes in behavior among pantry patrons.

Abstract
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). Preference ratings using 3-point Likert scale were analyzed over 35 weeks. RESULTS For 57 FVs rated for preference, ratings revealed that F had higher frequency of children choosing "I like it" than for V (78% F; 38.2% V; p < .05) and liking distribution was different between F and V (p < .001). Significant relations were found between liking and: (1) grade (r = -0.02, p = .02), and (2) time (r = -0.09, p < .001). Models indicated that V served (β = -0.40), timepoint (β = -0.07), and grade level (β = -0.02) accounted for significant variance for preference ratings (R2 = 0.17, p < .001), indicating that preference ratings declined over time. CONCLUSIONS Fruits were preferred over vegetables. Overall preference ratings were negatively impacted by time, grade level, and vegetables served. Being exposed one time to a variety of FVs did not improve ratings for vegetables.

Customized optical mapping by CRISPR-Cas9 mediated DNA labeling with multiple sgRNAs. Nucleic Acids Res 2021; 49:e8. [PMID: 33231685 PMCID: PMC7826249 DOI: 10.1093/nar/gkaa1088] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2020] [Revised: 10/16/2020] [Accepted: 10/27/2020] [Indexed: 01/01/2023] Open
Abstract
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. In this report, we present customized mapping strategies that extend the applications of CRISPR-Cas9 DNA labeling. We first design a CRISPR-Cas9 labeling strategy to interrogate and differentiate the single allele differences in NGG protospacer adjacent motifs (PAM sequence). Combined with sequence motif labeling, we can pinpoint the single-base differences in highly conserved sequences. In the second strategy, we design mapping patterns across a genome by selecting sets of specific single-guide RNAs (sgRNAs) for labeling multiple loci of a genomic region or a whole genome. By developing and optimizing a single tube synthesis of multiple sgRNAs, we demonstrate the utility of CRISPR-Cas9 mapping with 162 sgRNAs targeting the 2Mb Haemophilus influenzae chromosome. These CRISPR-Cas9 mapping approaches could be particularly useful for applications in defining long-distance haplotypes and pinpointing the breakpoints in large structural variants in complex genomes and microbial mixtures.

Training Preferences of School Food Service Staff Vary by Role in the School Nutrition Program. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 18:E50. [PMID: 33374767 PMCID: PMC7795387 DOI: 10.3390/ijerph18010050] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 10/31/2020] [Revised: 12/19/2020] [Accepted: 12/21/2020] [Indexed: 06/12/2023]
Abstract
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. rural), or job experience. Participants completed surveys that included questions on demographics and preferences for learning methods and training topics (n = 492). Descriptive statistics characterized survey responses. Chi square tests assessed differences in learning method and training topic preferences by participant role, locale, and job experience; Cramer's V assessed the strength of association for each chi square result. Qualitative responses to open-ended questions were analyzed using an inductive thematic analysis method. Nearly all training topic preferences were significantly different (p < 0.001 using Bonferroni method) when stratified by role. Significant differences were also observed for school locale and years of experience, but to a lesser degree. There was less variation in learning method preferences across staff role. Qualitative results (n = 93) identified three key themes related to training needs: role-specific trainings, innovative learning methods, and geographic access. The combination of quantitative and qualitative analysis indicate that professional development for SNPs should mostly be conducted in-person, be easily accessible, and include hands-on activities. Further, training should be tailored by job role and address situational barriers unique to the geographic area.

Single-molecule analysis of subtelomeres and telomeres in Alternative Lengthening of Telomeres (ALT) cells. BMC Genomics 2020; 21:485. [PMID: 32669102 PMCID: PMC7364475 DOI: 10.1186/s12864-020-06901-7] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2020] [Accepted: 07/08/2020] [Indexed: 02/03/2023] Open
Abstract
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. RESULTS Our results revealed loci-specific ALT telomere features. For example, while each subtelomere included examples of single molecules with terminal (TTAGGG) n tracts as well as examples of recombinant telomeric single molecules, the ratio of these molecules was subtelomere-specific, ranging from 33:1 (19p) to 1:25 (19q) in U2OS. The Saos-2 cell line shows a similar percentage of recombinant telomeres. The frequency of recombinant subtelomeres of SK-MEL-2 (11%) is about half that of U2OS and Saos-2 (24 and 19% respectively). Terminal (TTAGGG) n tract lengths and heterogeneity levels, the frequencies of telomere signal-free ends, and the frequency and size of retained internal telomere-like sequences (ITSs) at recombinant telomere fusion junctions all varied according to the specific subtelomere involved in a particular cell line. Very large linear extrachromosomal telomere repeat (ECTR) DNA molecules were found in all three cell lines; these are in principle capable of templating synthesis of new long telomere tracts via break-induced repair (BIR) long-tract DNA synthesis mechanisms and contributing to the very long telomere tract length and heterogeneity characteristic of ALT cells. Many of longest telomere tracts (both end-telomeres and linear ECTRs) displayed punctate CRISPR/Cas9-dependent (TTAGGG) n labeling patterns indicative of interspersion of stretches of non-canonical telomere repeats. CONCLUSION Identifying individual subtelomeres and characterizing linked telomere (TTAGGG) n tract lengths and structural changes using our new single-molecule methodologies reveals the structural consequences of telomere damage, repair and recombination mechanisms in human ALT cells in unprecedented molecular detail and significant differences in different ALT-positive cell lines.

The Driver of Extreme Human-Specific Olduvai Repeat Expansion Remains Highly Active in the Human Genome. Genetics 2020; 214:179-191.

Abstract
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 NBPF genes in the chromosomal 1q21.1-0.2 region, are primarily responsible for the striking human-specific copy number increase. Interestingly, most of the Olduvai triplets are adjacent to, and transcriptionally coregulated with, three human-specific NOTCH2NL genes that have been shown to promote cortical neurogenesis. Until now, the underlying genomic events that drove the Olduvai hyperamplification in humans have remained unexplained. Here, we show that the presence or absence of an alternative first exon of the Olduvai triplet perfectly discriminates between amplified (58/58) and unamplified (0/12) triplets. We provide sequence and breakpoint analyses that suggest the alternative exon was produced by an nonallelic homologous recombination-based mechanism involving the duplicative transposition of an existing Olduvai exon found in the CON3 domain, which typically occurs at the C-terminal end of NBPF genes. We also provide suggestive in vitro evidence that the alternative exon may promote instability through a putative G-quadraplex (pG4)-based mechanism. Lastly, we use single-molecule optical mapping to characterize the intragenic structural variation observed in NBPF genes in 154 unrelated individuals and 52 related individuals from 16 families and show that the presence of pG4-containing Olduvai triplets is strongly correlated with high levels of Olduvai copy number variation. These results suggest that the same driver of genomic instability that allowed the evolutionarily recent, rapid, and extreme human-specific Olduvai expansion remains highly active in the human genome.

Abstract
Background Escherichia coli C forms more robust biofilms than other laboratory strains. Biofilm formation and cell aggregation under a high shear force depend on temperature and salt concentrations. It is the last of five E. coli strains (C, K12, B, W, Crooks) designated as safe for laboratory purposes whose genome has not been sequenced. Results Here we present the complete genomic sequence of this strain in which we utilized both long-read PacBio-based sequencing and high resolution optical mapping to confirm a large inversion in comparison to the other laboratory strains. Notably, DNA sequence comparison revealed the absence of several genes thought to be involved in biofilm formation, including antigen 43, waaSBOJYZUL for lipopolysaccharide (LPS) synthesis, and cpsB for curli synthesis. The first main difference we identified that likely affects biofilm formation is the presence of an IS3-like insertion sequence in front of the carbon storage regulator csrA gene. This insertion is located 86 bp upstream of the csrA start codon inside the − 35 region of P4 promoter and blocks the transcription from the sigma32 and sigma70 promoters P1-P3 located further upstream. The second is the presence of an IS5/IS1182 in front of the csgD gene. And finally, E. coli C encodes an additional sigma70 subunit driven by the same IS3-like insertion sequence. Promoter analyses using GFP gene fusions provided insights into understanding this regulatory pathway in E. coli. Conclusions Biofilms are crucial for bacterial survival, adaptation, and dissemination in natural, industrial, and medical environments. Most laboratory strains of E. coli grown for decades in vitro have evolved and lost their ability to form biofilm, while environmental isolates that can cause infections and diseases are not safe to work with. Here, we show that the historic laboratory strain of E. coli C produces a robust biofilm and can be used as a model organism for multicellular bacterial research. Furthermore, we ascertained the full genomic sequence of this classic strain, which provides for a base level of characterization and makes it useful for many biofilm-based applications.

Abstract
OBJECTIVE To identify participant characteristics and study methodology that influenced the completion of a 15-month community-based longitudinal study evaluating the impact of the Supplemental Nutrition Assistance Program Education and Expanded Food and Nutrition Education Program. DESIGN Observational longitudinal 15-month study across 12 data collection timepoints. Sociodemographic characteristics were collected with a paper-based survey at baseline. SETTING Five counties across central and southern Illinois. PARTICIPANTS Women, aged 18 to 65 years (n = 297), recruited at sites likely to serve families eligible for the Supplemental Nutrition Assistance Program Education and Expanded Food and Nutrition Education Program (housing departments, child care centers, etc). MAIN OUTCOME MEASURES Predictors of participant attrition during the study duration. ANALYSIS Cox proportional hazard models. RESULTS Ninety-seven participants were retained across the full study. In unadjusted models, greater income and education levels were significantly related to lower attrition; however, this relationship did not persist in a multivariate model. When adjusted for other characteristics, larger household size was the only measured variable significantly related to greater odds of attrition (odds ratio = 1.09; 95% confidence interval = 1.02, 1.17). CONCLUSIONS AND IMPLICATIONS Several characteristics predicting attrition in other settings were not significant in this study. Future attrition analyses that evaluate social support, transportation capacity, and type of phone in longitudinal nutrition education studies are warranted.

Abstract
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. One hundred and fifty-three caregiver-child dyads (n = 103 in the HH group; n = 50 in the NE group) participated in the study. HH is an evidence-based dietary and physical activity intervention for low-income preschool children. The NE curriculum provided lessons for children that are consistent with the Dietary Guidelines for Americans 2010. Data were collected on demographics, anthropometrics, and behavioral variables for parent-child dyads at baseline and postintervention. Mixed model methods with random effects for site and participant were utilized. No differences in child or caregiver diet, physical activity, or screen time by group were found. No between-group differences in child BMI z-score were found; however, caregivers in the HH group lost significantly more weight than those in the NE group. Results from this trial can inform future dissemination efforts of evidenced-based programs for underserved families.

Abstract
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. After revisions, the NEFPAT was used in 27 pantries. RESULTS Pilot tests indicated positive appraisal for the NEFPAT and recommendations were addressed. The NEFPAT's 6 objectives and the overall tool were rated as content valid by experts, with an average section rating of 3.85 ± 0.10. Intraclass correlation coefficients for interrater reliability were >0.90. CONCLUSIONS AND IMPLICATIONS The NEFPAT is content valid with high interrater reliability. It provides baseline data that could be valuable for interventions within the nutrition environment of food pantries.

Abstract
Abstract
Background
Pregnancy associated breast cancer (PABC) is defined as breast cancer (BC) diagnosed during the gestational period (GP) or in the first year postpartum (PP). Despite its infrequent occurrence, the incidence of PABC appears to be rising due to the increasing propensity for women to delay childbirth. We have established the first combined prospective and retrospective registry study of PABC in Ireland to examine specific clinicopathological characteristics, treatments and maternal outcomes. We present the retrospective findings to date.
Methods
We performed a retrospective multicentre observational study of patients (pts) with PABC treated in the eight Irish cancer centres from August 2001 to March 2017. Data extracted included information on pt demographics, tumour biology, staging, treatment administered and maternal outcomes. Standard biostatistical methods were used for analysis.
Results
111 PABC patients were identified. Sixty pts (54%) were diagnosed during the GP and 51 (46%) within 1 year PP. Median age at diagnosis was 36 years (yrs). Table 1 illustrates baseline characteristics. Two thirds of pts were node positive and a similar proportion had grade 3 pathology. Seventy pts (63%) were estrogen receptor (ER) positive, 36 (32%) HER2 positive, 25 (22%) triple negative. Twenty-two pts (20%) were metastatic at presentation. Seven pts (6%) had a known BRCA 1/2 mutation. The median OS (overall survival) and DFS (disease free survival) for the entire cohort was 107.4 and 94.2 months respectively (resp). There was no survival difference between those diagnosed during the GP versus PP. 5 yr DFS and OS was 68.6% and 69.2% resp. This compares unfavourably to results reported by the National Cancer Registry of Ireland in a similar age-matched BC population between 2000-2012 where the 5 yr OS was 86.5%. Variables in our study associated with poorer outcomes included younger age, tumour size, node positivity and lack of estrogen expression.

Conclusions
PABC patients may have a poorer outcome. Our study reported higher rates of triple negative and HER2 positive breast cancer which are associated with more aggressive biology. Prospective evaluation of clinicopathological features, pharmacokinetics of treatments selected and maternal and fetal outcomes is imperative in this distinct pt group.

Abstract
OBJECTIVE To examine Internet access and interest in receiving nutrition education via social media applications among low-income adults participating in the Supplemental Nutrition Assistance Program Education (SNAP-Ed). METHODS A cross-sectional survey was distributed during 25 SNAP-Ed classes throughout the 16 southernmost counties of Illinois. RESULTS From 188 responses, the majority of participants had Internet access (76%). Among participants aged 18-32 years (n = 51), 92% owned a smartphone with Internet access and 57% indicated that they would use online nutrition education, with most interest in e-mail (41%), Facebook (40%), and text messaging (35%). There was little interest in using blogs, Vine, Twitter, Tumblr, and Pinterest. Overall, 49% of middle-aged adults aged 33-64 years and 87% of seniors aged ≥65 years reported they would not use online nutrition education. CONCLUSIONS AND IMPLICATIONS Results indicated similar Internet accessibility in southern Illinois among low-income populations compared with national rural rates. Interest in using online nutrition education varied among SNAP-Ed participants according to age. Young adults appeared to be the most captive audience regarding online nutrition education. Results may be useful to agencies implementing SNAP-Ed to supplement current curriculum with online nutrition education for audiences aged ≤32 years.

Abstract
We have developed a novel method that enables global subtelomere and haplotype-resolved analysis of telomere lengths at the single-molecule level. An in vitro CRISPR/Cas9 RNA-directed nickase system directs the specific labeling of human (TTAGGG)n DNA tracts in genomes that have also been barcoded using a separate nickase enzyme that recognizes a 7-bp motif genome-wide. High-throughput imaging and analysis of large DNA single molecules from genomes labeled in this fashion using a nanochannel array system permits mapping through subtelomere repeat element (SRE) regions to unique chromosomal DNA while simultaneously measuring the (TTAGGG)n tract length at the end of each large telomere-terminal DNA segment. The methodology also permits subtelomere and haplotype-resolved analyses of SRE organization and variation, providing a window into the population dynamics and potential functions of these complex and structurally variant telomere-adjacent DNA regions. At its current stage of development, the assay can be used to identify and characterize telomere length distributions of 30–35 discrete telomeres simultaneously and accurately. The assay's utility is demonstrated using early versus late passage and senescent human diploid fibroblasts, documenting the anticipated telomere attrition on a global telomere-by-telomere basis as well as identifying subtelomere-specific biases for critically short telomeres. Similarly, we present the first global single-telomere-resolved analyses of two cancer cell lines.

Abstract
OBJECTIVE The US Department of Agriculture Fresh Fruit and Vegetable Program (FFVP) allows schools to increase fruit and vegetable (FV) exposure by distributing FV as snacks. The objective of this study was to compare kindergarten through second (K-2nd)-graders who were exposed or not to FFVP for preferences and identification. DESIGN, SETTING, PARTICIPANTS The FV Preference Survey for K-2nd-graders contained 12 fruits and 12 vegetables, a 3-Likert scale (liked it, okay, don't like it), and an I don't know option. Data were collected from K-2nd-graders at 2 elementary schools near Chicago, IL (n = 435, FFVP school, n = 235 with 12 teachers; non-FFVP school, n = 200 with 10 teachers). MAIN OUTCOME MEASURE(S) Mean preference scores. ANALYSIS Chi-square, Mann-Whitney U, and multiple linear regression analyses compared school data (P < .05). RESULTS There were significant differences in mean preference scores, with higher fruit scores at the FFVP school (1.8 ± 0.6) than at the non-FFVP school (1.7 ± 0.6). In contrast, there was a higher vegetable score for the non-FFVP school (1.3 ± 0.9) than for the FFVP school (1.2 ± 0.9). The school variable had weak impact on fruit ranking (multivariate coefficient = 0.01; P < .05). For fruits and vegetables and combined, there were fewer I don't know responses in the FFVP (χ2 = 149.080; P < .01). CONCLUSIONS AND IMPLICATIONS At the FFVP school, fewer I don't know responses suggested better FV identification. Non-FFVP students had higher vegetable preferences than did FFVP students. Tasting a variety of FV may help with identifying FV, but more research is needed to determine the impact on preferences.

Abstract
Accurate maps and DNA sequences for human subtelomere regions, along with detailed knowledge of subtelomere variation and long-range telomere-terminal haplotypes in individuals, are critical for understanding telomere function and its roles in human biology. Here, we use a highly automated whole genome mapping technology in nano-channel arrays to analyze large terminal human chromosome segments extending from chromosome-specific subtelomere sequences through subtelomeric repeat regions to terminal (TTAGGG)n repeat tracts. We establish detailed maps for subtelomere gap regions in the human reference sequence, detect many new large subtelomeric variants and demonstrate the feasibility of long-range haplotyping through segmentally duplicated subtelomere regions. These features make the method a uniquely valuable new tool for improving the quality of genome assemblies in complex DNA regions. Based on single molecule mapping of telomere-terminal DNA fragments, we provide proof of principle for a novel method to estimate telomere lengths linked to distinguishable telomeric haplotypes; this single-telomere genotyping method may ultimately enable delineation of human cis elements involved in telomere length regulation.

Abstract
Abstract
Catastrophic genomic alterations may drive aggressive cancer phenotypes. We describe a diagnostically challenging and rapidly fatal case of medullary thyroid carcinoma (MTC) occurring in a young, morbidly obese man presenting with diffuse bone marrow involvement and disseminated intravascular coagulation. Whole-exome (WES) and shallow whole-genome sequencing (sWGS) were carried out for the primary tumour, adjacent normal, bone marrow tissues, multiple metastases and blood samples derived from the patient. We identified three germline single nucleotide polymorphisms (SNPs) within the RET proto-oncogene that remained undetected using routine hospital genetic testing procedures. One variant (L769L) has been previously reported to be associated with aggressive MTC presentation yet remains untested for in the routine diagnosis of MTC. Supported by findings from both WES and sWGS, we report for the first time in thyroid cancer on the occurrence of a “chromothripsis-like pattern”, which involved shattering of chromosome 4 leading to complete abrogation of normal chromosomal function, along with dramatic widespread copy number aberrations across both primary tumour and bone marrow samples. Based on the somatic variants identified, we describe the evolutionary pathway of the case, showing that bone marrow metastasis occurred separately to other metastatic sites. The presence of disease-associated SNPs within the RET proto-oncogene supports their inclusion as part of routine genetic testing for MTC cases. The copy number aberrations and chromothripsis-like pattern affected a much broader range of genes than single mutations and may have led to the widespread chromosomal instability evident, possibly contributing to the rapid fatal course of the case. These results provide a rationale for the application of comprehensive genomic analysis of cancers presenting with unusual and aggressive phenotypes to facilitate more appropriate therapeutic options and diagnoses.

Abstract
OBJECTIVE To design a replicable training protocol for visual estimation of fruit and vegetable (FV) intake of kindergarten through second-grade students through digital photography of lunch trays that results in reliable data for FV served and consumed. METHODS Protocol development through literature and researcher input was followed by 3 laboratory-based trainings of 3 trainees. Lunchroom data collection sessions were done at 2 elementary schools for kindergarten through second-graders. Intraclass correlation coefficients (ICCs) were used. RESULTS By training 3, ICC was substantial for amount of FV served and consumed (0.86 and 0.95, respectively; P < .05). The ICC was moderate for percentage of fruits consumed (0.67; P = .06). In-school estimates for ICCs were all significant for amounts served at school 1 and percentage of FV consumed at both schools. CONCLUSIONS AND IMPLICATIONS The protocol resulted in reliable estimation of combined FV served and consumed using digital photography. The ability to estimate FV intake accurately will benefit intervention development and evaluation.

Community partnerships in healthy eating and lifestyle promotion: A network analysis. Prev Med Rep 2017; 6:294-301. [PMID: 28417062 PMCID: PMC5390690 DOI: 10.1016/j.pmedr.2017.03.007] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2016] [Revised: 02/07/2017] [Accepted: 03/13/2017] [Indexed: 11/25/2022] Open
Abstract
Promoting healthy eating and lifestyles among populations with limited resources is a complex undertaking that often requires strong partnerships between various agencies. In local communities, these agencies are typically located in different areas, serve diverse subgroups, and operate distinct programs, limiting their communication and interactions with each other. This study assessed the network of agencies in local communities that promote healthy eating and lifestyles among populations with limited resources. Network surveys were administered in 2016 among 89 agencies located in 4 rural counties in Michigan that served limited-resource audiences. The agencies were categorized into 8 types: K-12 schools, early childhood centers, emergency food providers, health-related agencies, social resource centers, low-income/subsidized housing complexes, continuing education organizations, and others. Network analysis was conducted to examine 4 network structures-communication, funding, cooperation, and collaboration networks between agencies within each county. Agencies had a moderate level of cooperation, but were only loosely connected in the other 3 networks, indicated by low network density. Agencies in a network were decentralized rather than centralized around a few influential agencies, indicated by low centralization. There was evidence regarding homophily in a network, indicated by some significant correlations within agencies of the same type. Agencies connected in any one network were considerably more likely to be connected in all the other networks as well. In conclusion, promoting healthy eating and lifestyles among populations with limited resources warrants strong partnership between agencies in communities. Network analysis serves as a useful tool to evaluate community partnerships and facilitate coalition building.

Abstract
OBJECTIVES We assessed the network of agencies in local communities that promote healthy eating and lifestyles among populations with limited resources. METHODS Network surveys were administered among 159 Illinois agencies identified as serving limited-resource audiences categorized into 8 types: K-12 schools, early childhood centers, emergency food providers, health-related agencies, social resource centers, low-income/subsidized housing complexes, continuing education organizations, and others. Network analysis was conducted to examine 4 network structures - communications, funding, cooperation, and collaboration networks between agencies within each county/county cluster. RESULTS Agencies in a network were found to be loosely connected, indicated by low network density. Reporting accuracy might be of concern, indicated by low reciprocity. Agencies in a network are decentralized rather than centralized around a few influential agencies, indicated by low betweenness centrality. There is suggestive evidence regarding homophily in a network, indicated by some significant correlations within agencies of the same type. Agencies connected in one network are significantly more likely to be connected in all the other networks as well. CONCLUSIONS Promoting healthy eating and lifestyles among populations with limited resources warrants strong partnership across agencies in communities. Network analysis serves as a useful tool to evaluate community partnerships and facilitate coalition building..

Promotoras and the Semantic Gap Between Latino Community Health Researchers and Latino Communities. Health Promot Pract 2016; 18:444-453.

Abstract
Promotoras are identified as a unique group of community health workers adept at reducing health disparities. This qualitative study was conducted to better understand perceptions of the term promotora, broadly used in research but not well documented in everyday Latina vocabulary. Six focus groups to better understand perceptions of the term promotora were conducted with 36 Latina women living in three nonmetropolitan areas in Illinois. Results suggest that Latina participants in the study do not understand the meaning of "promotora" in the same way as it is used in the literature. Latina participants understood "promotoras" as referring to people who sell or deliver information, or organize events in the community that are not necessarily related to health events or community health work. Furthermore, they usually understood the term to refer to paid work rather than volunteering. Results underscore the importance of being sensitive to Latinas' perceptions of community health terminology by assessing their context, needs, and expectations. These findings call researchers' attention to the need to educate certain Latino communities about the concept of promotoras, with implications for the implementation and dissemination of promotora-led community health programs, as the semantic discrepancy could affect the recruitment of promotoras as well as community participation in the programs they deliver.

Accrual to Cancer Clinical Trial. IRISH MEDICAL JOURNAL 2016; 109:436. [PMID: 27834087] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Indexed: 06/06/2023]
Abstract
Accrual to cancer clinical trials (CCT) is imperative to safeguard continued improvement in cancer outcomes. A retrospective chart review was performed of patients (n=140) starting a new anti-cancer agent in a north Dublin cancer centre. This review was performed over a four-month period, beginning in November 2015. Only 29% (n=41) had a CCT option. The overall accrual rate to CCT was 5% (n=7), which is comparable to internationally reported figures. The main reasons for failure to recruit to CCT included the lack of a CCT option for cancer type (n=30, 23%), stage (n=25, 19%), and line of treatment (n=23, 17%). Over the last decade, the rate of accrual to CCTs has in fact doubled and the number of trials open to recruitment has tripled. Ongoing governmental and philanthropic support is necessary to continue this trend to further expand CCT patient options with a target accrual rate of 10%.
