Rice seeds biofortification using biogenic iron oxide nanoparticles synthesized by using Glycyrrhiza glabra: a study on growth and yield improvement.

Iron, a crucial micronutrient, is an integral element of biotic vitality. The scarcity of iron in the soil creates agronomic challenges and has a detrimental impact on crop vigour and chlorophyll formation. Utilizing iron oxide nanoparticles (IONPs) via nanopriming emerges as an innovative method to enhance agricultural efficiency and crop health. The objective of this study was to synthesize biogenic IONPs from Glycyrrhiza glabra (G. glabra) plant extract using green chemistry and to evaluate their nanopriming effects on rice seed iron levels and growth. The synthesized IONPs were analyzed using UV-Vis spectroscopy, Fourier-transform infrared spectroscopy (FTIR), Scanning electron microscope (SEM), Transmission electron microscopy (TEM), and Energy-dispersive X-ray (EDX) techniques. The UV-Vis peak at 280 nm revealed the formation of IONPs. SEM and TEM showed that the nanoparticles were spherical and had an average diameter of 23.8 nm. Nanopriming resulted in a substantial enhancement in growth, as seen by a 9.25% and 22.8% increase in shoot lengths for the 50 ppm and 100 ppm treatments, respectively. The yield metrics showed a positive correlation with the concentrations of IONPs. The 1000-grain weight and spike length observed a maximum increase of 193.75% and 97.73%, respectively, at the highest concentration of IONPs. The study indicates that G. glabra synthesized IONPs as a nanopriming agent significantly increased rice seeds' growth and iron content. This suggests that there is a relationship between the dosage of IONPs and their potential for improving agricultural biofortification.

Child Care Feeding Programs Associated With Food Security and Health for Young Children From Families With Low Incomes.

BACKGROUND: The Child and Adult Care Food Program is the primary national program that enables child-care settings to provide healthy meals for children. Associations between Child and Adult Care Food Program participation and child health and development and health care utilization are understudied. OBJECTIVE: To assess associations between children's health, development, health care utilization and food security by meal source (child-care-provided vs parent-provided) among children from low-income families with a child care subsidy attending child-care in settings likely eligible to participate in Child and Adult Care Food Programs. DESIGN: The study used repeat cross-sectional surveys (new sample at successive time points) conducted year-round. PARTICIPANTS AND SETTING: Primary caregivers of 3,084 young children accessing emergency departments or primary care in Baltimore, MD; Boston, MA; Little Rock, AR; Minneapolis, MN; and Philadelphia, PA, were interviewed between 2010 and 2020. The sample was limited to children aged 13 to 48 months, receiving a child care subsidy and attending child-care centers or family child-care homes ≥20 hours per week. MAIN OUTCOME MEASURES: Outcomes included household and child food security; child health, growth, and developmental risk; and admission to the hospital on the day of the emergency department visit. STATISTICAL ANALYSES: Meal source and participant characteristics were analyzed using χ2 tests; associations of outcomes with parent-provided meals were analyzed with adjusted logistic regression. RESULTS: The majority of children had child-care-provided meals (87.2% child-care-provided vs 12.8% parent-provided). Compared with children with parent-provided meals, children with child-care-provided meals had lower adjusted odds of living in a food-insecure household (adjusted odds ratio 0.70, 95% CI 0.55 to 0.88), being in fair or poor health (adjusted odds ratio 0.61, 95% CI 0.46 to 0.81), or hospital admission from the emergency department (adjusted odds ratio 0.59, 95% CI 0.41 to 0.83), with no differences in growth or developmental risk. CONCLUSIONS: Compared with meals provided from home, child-care-provided meals likely supported by the Child and Adult Care Food Program are related to food security, early childhood health, and reduced hospital admissions from an emergency department among low-income families with young children.

Trends in Food Insecurity and SNAP Participation among Immigrant Families U.S.-Born Young Children.

Immigrant families are known to be at higher risk of food insecurity compared to non-immigrant families. Documented immigrants in the U.S. <5 years are ineligible for the Supplemental Nutrition Assistance Program (SNAP). Immigration enforcement, anti-immigrant rhetoric, and policies negatively targeting immigrants have increased in recent years. Anecdotal reports suggest immigrant families forgo assistance, even if eligible, related to fear of deportation or future ineligibility for citizenship. In the period of January 2007-June 2018, 37,570 caregivers of young children (ages 0-4) were interviewed in emergency rooms and primary care clinics in Boston, Baltimore, Philadelphia, Minneapolis, and Little Rock. Food insecurity was measured using the U.S. Department of Agriculture's Food Security Survey Module. Overall, 21.4% of mothers were immigrants, including 3.8% in the U.S. <5 years ("<5 years") and 17.64% ≥ 5 years ("5+ years"). SNAP participation among <5 years families increased in the period of 2007-2017 to 43% and declined in the first half of 2018 to 34.8%. For 5+ years families, SNAP participation increased to 44.7% in 2017 and decreased to 42.7% in 2018. SNAP decreases occurred concurrently with rising child food insecurity. Employment increased 2016-2018 among U.S.-born families and was stable among immigrant families. After steady increases in the prior 10 years, SNAP participation decreased in all immigrant families in 2018, but most markedly in more recent immigrants, while employment rates were unchanged.
