    Abstract This study evaluated the nutritional, economic, and environmental impacts of a Meatless Monday (MM) National School Lunch Program (NSLP) in a large urban US school district. After averaging the nutrient content of entrees across the week and comparing changes relative to recommendations, there were no pre-post differences >15%. Monday entrees offered post-MM required considerably less water to produce (−51%) and were associated with fewer greenhouse gas emissions (−74%). The MM program had little impact on entrée cost (−2.5%). Further research is needed to determine how MM program goals can be achieved within the NSLP context.

    Abstract Chemotherapy often generates intratumoral senescent cancer cells that strongly modify the tumor microenvironment, favoring immunosuppression and tumor growth. We discovered, through an unbiased proteomics screen, that the immune checkpoint inhibitor programmed cell death 1 ligand 2 (PD-L2) is highly upregulated upon induction of senescence in different types of cancer cells. PD-L2 is not required for cells to undergo senescence, but it is critical for senescent cells to evade the immune system and persist intratumorally. Indeed, after chemotherapy, PD-L2-deficient senescent cancer cells are rapidly eliminated and tumors do not produce the senescence-associated chemokines CXCL1 and CXCL2. Accordingly, PD-L2-deficient pancreatic tumors fail to recruit myeloid-derived suppressor cells and undergo regression driven by CD8 T cells after chemotherapy. Finally, antibody-mediated blockade of PD-L2 strongly synergizes with chemotherapy causing remission of mammary tumors in mice. The combination of chemotherapy with anti-PD-L2 provides a therapeutic strategy that exploits vulnerabilities arising from therapy-induced senescence.

    Abstract Background: Lung disease after tuberculous confers significant morbidity. However, the determinants of persistent lung damage in TB are not well established. We investigated associations between TB-associated radiologic changes and sociodemographic factors, surrogates of bacillary burden, and blood inflammatory markers at initiation of therapy and after 1 month.
    Research question: What are the predictors of radiologic severity at the end of TB treatment for TB?
    Study design and methods: We collected data from patients treated for drug-sensitive pulmonary TB at our center over a 5.5-year period. We recorded age, sex, ethnicity, smoking status, symptom duration, sputum smear grade, time to culture positivity, and blood results (C-reactive protein and neutrophil count) at baseline and after 1 month of treatment. Chest radiographs obtained at baseline, 2 months, and end of treatment were assessed independently by two radiologists and scored using a validated system. Relationships between predictor variables and radiologic outcomes were assessed using linear or binary logistic regression.
    Results: We assessed 154 individuals with a mean age of 37 years, 63% of whom were men. In a multivariate analysis, baseline radiologic severity correlated with sputum smear grade (P = 0.003) and neutrophil count (P < 0.001). At end of treatment, only the 1-month neutrophil count was associated significantly with overall radiologic severity in the multivariate analysis (r = 0.34; P = 0.003) and remained significant after controlling for baseline radiologic scores. The 1-month neutrophil count also was the only independent correlate of volume loss and pleural thickening at the end of treatment and was significantly higher in patients with persistent cavitation or effusion vs those without.
    Interpretation: Persistent neutrophilic inflammation after 1 month of TB therapy is associated with poor radiologic outcome, suggesting a target for interventions to minimize lung disease after tuberculous.

    Abstract Objective: To determine predictors of fluid milk waste in a Breakfast in the Classroom School Breakfast Program.
    Design: Cross-sectional with 3 repeated measures/classroom.
    Setting: Elementary schools in a medium-sized, low-income, urban school district.
    Participants: Twenty third- through fourth-grade classrooms across 6 schools.
    Main outcomes: Dependent variables include percentage of total and served milk wasted. Independent variables included observed daily menu offerings, program factors, and teacher and student behavior.
    Analysis: Descriptive statistics were used to characterize variables across classrooms and schools. Multilevel mixed-effects models were used to test associations between predictors and outcomes of interest. P ≤ .05 was considered statistically significant.
    Results: Total milk waste increased 12% when juice was offered and 3% for each additional carton of unserved milk. Teacher encouragement to take and/or consume breakfast was associated with a 5% and 9% increase in total and served milk waste, respectively. When students were engaged in other activities in addition to eating breakfast, total milk waste decreased 10%.
    Conclusions and implications: Beverage offerings were predictive of greater total milk waste. Teacher and student behavior also appeared to influence milk consumption. Findings suggest that specific changes to School Breakfast Program implementation policies and practices could have an important role in waste mitigation.

    Abstract Objectives: To measure fluid milk waste in a US School Breakfast in the Classroom Program and estimate its nutritional, economic, and environmental effects.
    Methods: Fluid milk waste was directly measured on 60 elementary school classroom days in a medium-sized, urban district. The US Department of Agriculture nutrition database, district cost data, and carbon dioxide equivalent (CO
    Results: Of the total milk offered to School Breakfast Program participants, 45% was wasted. A considerably smaller portion of served milk was wasted (26%). The amount of milk wasted translated into 27% of vitamin D and 41% of calcium required of School Breakfast Program meals. The economic and environmental costs amounted to an estimated $274 782 (16% of the district's total annual School Breakfast Program food expenditures), 644 893 kilograms of CO
    Conclusions: These substantial effects of milk waste undermine the School Breakfast Program's capacity to ensure short- and long-term food security and federal food waste reduction targets. Interventions that reduce waste are urgently needed.

    Abstract Limited research has examined the rapid growth of farm to school (FTS) programs in the US. Qualitative interviews (n = 24) framed by Diffusion of Innovations theory were used to explore FTS program adoption and expansion in Massachusetts. Program compatibility and relative advantages related to academics, school meal participation, and child health motivated initial engagement. Active classroom integration, implementation simplification, and strong support networks aided program expansion. Leadership and sustainability plans, garden maintenance partnerships, and Community Eligibility Provision participation hold promise to help further program diffusion. Future research should focus on providing additional evidence for FTS aspects salient to adoption and expansion.

    Abstract Despite significant efforts to improve pancreatic ductal adenocarcinoma (PDAC) clinical outcomes, overall survival remains dismal. The poor response to current therapies is partly due to the existence of pancreatic cancer stem cells (PaCSCs), which are efficient drivers of PDAC tumorigenesis, metastasis and relapse. To find new therapeutic agents that could efficiently kill PaCSCs, we screened a chemical library of 680 compounds for candidate small molecules with anti-CSC activity, and identified two compounds of a specific chemical series with potent activity in vitro and in vivo against patient-derived xenograft (PDX) cultures. The anti-CSC mechanism of action of this specific chemical series was found to rely on induction of lysosomal membrane permeabilization (LMP), which is likely associated with the increased lysosomal mass observed in PaCSCs. Using the well characterized LMP-inducer siramesine as a tool molecule, we show elimination of the PaCSC population in mice implanted with tumors from two PDX models. Collectively, our approach identified lysosomal disruption as a promising anti-CSC therapeutic strategy for PDAC.

    Abstract Recent increases in consumer demand for local food have resulted in more opportunities for food to be purchased in close proximity to where it is produced. However, local markets can be challeng­ing retail outlets for farmers and not uniformly affordable and accessible to all consumers. Farmers market nutrition incentive (FMNI) and farm to school (F2S) programs are two community-based initiatives that support farmers while simultane­ously lessening the burden of local food access for lower income populations. In this study, we explore farmer perceptions, barriers to adoption, and impacts of FMNI and F2S programs. A survey was developed based on the Diffusion of Innova­tions theory to assess (1) the key factors that influ­ence adoption of FMNI and F2S programs; (2) farmer perceptions of the most significant barriers to program adoption; and (3) the influence of non-economic impacts on farmers’ motivation to participate in those programs. A total of 155 Mid-Atlantic fruit and vegetable farmers completed the survey. Participating farmers perceived FMNI and F2S as providing advantageous social impact and various economic opportunities. However, partici­pants and non-participants had differing perspec­tives on program complexity, compatibility with their business model, and the degree to which others have succeeded when participating. The most significant barriers relate to issues with prod­uct pricing, customer engagement, and logistics. Three-quarters of farmers ranked social/commu­nity impacts as most important to them. A deeper understanding of farmers’ involvement in FMNI and F2S programs will help address barriers and modify program components to increase econom­ic, social/community, and environmental impacts.
