Five year mortality in an RCT of a lung cancer biomarker to select people for low dose CT screening.

The role of biomarkers in risk-based early detection of lung cancer may enable screening to become cost effective and widely accessible. EarlyCDT-Lung is an example of such a blood-based autoantibody biomarker which may improve accessibility to Low dose Computed Tomography (LDCT) screening for those at highest risk. We randomized 12 208 individuals aged 50-75 at high risk of developing lung cancer to either the test or to standard clinical care.

Factors and Outcomes Associated With Using Scratch-Cooked, Organic, and Locally Grown Foods in School Meals in California.

Background: Incorporating scratch-cooked, organic, and locally grown foods into school meal programs can enhance meal quality and support local food systems.

Methods: 430 California school food authorities were surveyed to (1) evaluate their use of scratch-cooked, organic, and locally grown foods in their programs; (2) identify demographic and operational characteristics related to this use; and (3) analyze the relationship between serving more of these foods and perceived barriers to student meal participation. Poisson and logistic regression models, adjusted for SFAs' demographic characteristics, were used.

Infant diet quality index predicts nutrients of concern and ultra-processed food intake in low-income children in the United States.

Background: Diet quality during infancy can influence nutrient intake and ultra-processed foods (UPFs) consumption throughout later childhood.

Objectives: This study investigated the predictive validity of Infant Diet Quality Index (IDQI) scores from 0 to 1 y of age and consumption of select nutrients and UPFs at different time points in low-income children aged 2-5 y.

Methods: Dietary surveys and 24-h dietary recalls collected between ages 0 and 12 months from 2613 Special Supplemental Women, Infants, and Children Infant Toddler Feeding Practices Study-2 participants were used to assess infant diet quality by final IDQI score ranging from 0 (nonadherence to dietary guidelines) to 1 (complete adherence to guidelines).

Longer WIC Participation Is Associated With Higher Diet Quality and Consumption of WIC-Eligible Foods Among Children 2-5 Years Old.

Background: Few studies have evaluated trends in diet quality across early childhood, including the extent to which foods and beverages available in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) Food Package contribute to children's diets.

Objective: The objective of this study was to examine the following across ages 2 through 5 years: (1) trends in Healthy Eating Index-2020 (HEI-2020) total and component scores; (2) differences in mean HEI-2020 scores by WIC participation duration; and (3) contributions of the top 5 foods or beverages to HEI-2020 component scores by WIC duration.

Design: This was a secondary analysis of a nationally representative sample of the WIC Infant and Toddler Feeding Practices Study-2 conducted between 2013 and 2019.

The impact of a water promotion and access intervention on elementary school students in the presence of food insecurity.

Objective: School-based interventions encouraging children to replace sugar-sweetened beverages with water show promise for reducing child overweight. However, students with child food insecurity (CFI) may not respond to nutrition interventions like children who are food-secure.

Design: The Water First cluster-randomised trial found that school water access and promotion prevented child overweight and increased water intake.

Deriving and validating a risk prediction model for long COVID: a population-based, retrospective cohort study in Scotland.

Objectives: Using electronic health records, we derived and internally validated a prediction model to estimate risk factors for long COVID and predict individual risk of developing long COVID.

Design: Population-based, retrospective cohort study.

Setting: Scotland.

Looking to the past: Investigating 10-year place histories as a determinant of home food environments in the Healthy Communities Study.

Emerging research suggests there is a need to consider the importance of place histories in studying neighborhood effects. Guided by a life course of place framework, the objective of this study is to investigate the relationship between two place history exposures and three contemporary home food environment outcomes. Exposures included 10-year neighborhood socioeconomic status (SES) histories and multi-year nutrition community programming and policy (CPP) histories.

Perceptions and Experiences of Universal School Meals in California: Qualitative Insights From School Food Authorities on Participation, Stigma, and Operational Benefits and Challenges.

Background: Universal school meals (USM) aim to eliminate barriers to school meal access by providing free meals to all students regardless of family income. During the COVID-19 pandemic, US Department of Agriculture waivers allowed schools nationwide to offer meals free of charge to all students. Although USM have demonstrated positive effects on student health and participation, limited research has focused on the perspectives of the foodservice directors (FSDs) who manage them.

Water First School Water Promotion and Access Intervention: A Cost Analysis Study.

Background: Adequate water intake is associated with improved cognitive and physical performance, prevention of dental caries, and overweight and obesity. However, access to free drinking water in schools remains inadequate. Water First, a school-based intervention promoting water consumption, was shown effective in preventing overweight, yet its costs have not been quantified.

Household Food Insecurity Is Associated with Parental Perceptions of and Student Participation in School Meals.

Background/objectives: School meals are an important source of nutrition for children and have been found to help mitigate food insecurity. This study evaluated the association between food insecurity and school meal participation and whether parental perceptions about school meals differ by food security status.

Methods: In May 2022, 1110 Californian parents of K-12 students shared their perceptions about school meals, including meal quality, healthiness, stigma, and benefits, as well as their child's participation in school meals, in an online survey.

Child and Adult Care Food Program: Family Childcare Home Providers' Perceptions of Impacts of Increased Meal and Snack Reimbursement Rates during the COVID-19 Pandemic.

The U.S. Child and Adult Care Food Program (CACFP) provides tiered reimbursements for healthy foods for children at participating family childcare homes (FCCH).

Perceived Influence of a State-Level Universal Free School Meal Policy on Households With Varying Income Levels: An Analysis of Parental Perspectives.

Background: In the United States, a means-tested approach is often used to provide free or reduced-price meals (FRPM) to students from lower-income households. However, federal income thresholds do not account for regional cost of living variations. Thus, many ineligible households may be at risk for food insecurity.

The Addis Ababa toxicology curriculum project: educational needs assessment for the toxicology modules of an emergency medicine training program.

Background: The Toronto Addis Ababa Academic Collaboration in Emergency Medicine (TAAAC-EM) is a bi-institutional partnership between the University of Toronto (UofT) and Addis Ababa University (AAU) focused on addressing the need for emergency medicine (EM) postgraduate training and care in Ethiopia. Toxicology is a key competency in EM. EM physicians are often the first and sole clinicians to identify and treat patients presenting with a wide range of intoxications.

Background: The integration of smart technologies, including wearables and voice-activated devices, is increasingly recognized for enhancing the independence and well-being of older adults. However, the long-term dynamics of their use and the coadaptation process with older adults remain poorly understood. This scoping review explores how interactions between older adults and smart technologies evolve over time to improve both user experience and technology utility.

Transitioning sleeping position detection in late pregnancy using computer vision from controlled to real-world settings: an observational study.

Sleeping on the back after 28 weeks of pregnancy has recently been associated with giving birth to a small-for-gestational-age infant and late stillbirth, but whether a causal relationship exists is currently unknown and difficult to study prospectively. This study was conducted to build a computer vision model that can automatically detect sleeping position in pregnancy under real-world conditions. Real-world overnight video recordings were collected from an ongoing, Canada-wide, prospective, four-night, home sleep apnea study and controlled-setting video recordings were used from a previous study.

Rationale and Design of SCOT-HEART 2 Trial: CT Angiography for the Prevention of Myocardial Infarction.

Coronary artery disease continues to be the leading cause of death globally. Identifying patients who are at risk of coronary artery disease remains a public health priority. At present, the focus of cardiovascular disease prevention relies heavily on probabilistic risk scoring despite no randomized controlled trials demonstrating their efficacy.

Evaluating the Association of the Increase in the WIC Cash Value Benefit on the Diversity of MyPlate Fruits and Vegetables Redeemed and Consumed By Children in Low-Income Households.

Background: Fruits and vegetables (FV) are a critical source of nutrients, yet children in the United States are not meeting the Dietary Guidelines for Americans (DGA). The monthly FV cash value benefit (CVB) included in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC)'s food package to support child FV intake (FVI) received a substantial increase for economic relief during the COVID-19 pandemic.

Objectives: To evaluate how an expansion of the monthly WIC CVB to purchase FV for WIC children ages 1-4 y is associated with diversity in FV redeemed, and how changes in redeemed FV are related to FVI.
