How Do School Salad Bars Impact Elementary School Students' Dietary Quality and Energy Intake at Lunch? A Randomized Controlled Plate Waste Investigation.

Children's dietary quality is suboptimal, increasing the risk of numerous chronic illnesses. Salad bars (SBs) have potential to enhance children's nutritional intake within the National School Lunch Program (NSLP); yet, empirical support is lacking. To address this gap, we evaluated the impact of school salad bars on dietary quality and energy intake at lunch.

Fecal Hemoglobin Levels in Prior Negative Screening and Detection of Colorectal Neoplasia: A Dose-Response Meta-Analysis.

Background And Aims: Prior studies have shown that individuals with fecal hemoglobin (f-Hb) concentrations just below the positivity cutoff have an increased colorectal cancer risk compared with those with no or low f-Hb. Understanding the dose-response association between f-Hb in a prior screening round and the detection of colorectal neoplasia is crucial for tailoring risk-based screening recommendations.

Methods: We searched the literature to identify studies reporting the association between f-Hb in prior screening round and colorectal neoplasia detection in an average-risk population.

Harm-to-Benefit Ratio of Fecal Immunochemical Test-Based Screening for Colorectal Cancer Given Prior Fecal Hemoglobin Concentrations.

Background And Aims: This study aimed to provide evidence on the harm-to-benefit ratio of fecal immunochemical test (FIT)-based colorectal cancer (CRC) screening by previous fecal hemoglobin (f-Hb) concentrations, as reflected in the number needed to screen (NNS) and number needed to scope (NNSc).

Methods: Participants in up to 4 FIT screening rounds of the Dutch CRC screening program were included. The main outcomes of this study were the NNS and NNSc to detect 1 CRC and/or advanced neoplasia (AN) in screening rounds 2, 3, or 4, conditional on previous f-Hb concentrations.

Modelling the impact of bias in fecal immunochemical testing on long-term outcomes of colorectal cancer screening.

Background: As the impact of unmanaged bias (i.e. systematic source of inaccuracy) in fecal immunochemical test (FIT) analytical performance on long-term colorectal cancer (CRC) outcomes is unknown, we assessed the impact bias in FIT performance in an ongoing FIT-based CRC screening program.
