Strategies to improve enrollment in The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC): examining high coverage states and leveraging successful COVID-19 pandemic adjustments

The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) is an essential program in the USA providing food benefits and nutritional and breast-feeding support to low-income pregnant or postpartum women, infants and children at nutritional risk. Despite similarities amongst federal regulations shared across WIC programs at the state level, important differences in the operations, policies and technologies between states exist. Nationally, nearly half of women, infants and children who were eligible to receive WIC benefits in 2018 were not participating in the program. In this paper, we evaluate common practices exhibited by states with the highest and lowest WIC coverage rates to identify strategies that may improve enrollment and retention rates in regions with low WIC coverage rates. We use WIC as a case study for identifying strategies that can be broadly applied to improve utilisation of similar food assistance programs globally, particularly those benefiting low-income women and children. The four strategies discussed here include utilising data to check adjunctive eligibility and reach eligible non-participants, increasing public awareness of WIC through outreach and referral efforts, implementing a centralised smartphone app and linking personal electronic benefits and streamlining the use of technologies for online applications, participant portals and remote communication. In most states, the COVID-19 pandemic and the federal waivers issued in response have offered the opportunity to promptly implement some of these strategies, particularly with regard to remote communication capabilities. With proper resources and implementation, these strategies can improve utilisation of WIC and similar programs globally.

Programming of human monocytes by the uteroplacental environment

During human pregnancy, monocytes recruited to the uterus (decidua) are modified to promote immune defense and semiallogeneic pregnancy. The purpose of this study was to identify decidual factors involved in programming of monocytes into decidual macrophages by comparing the surface and secretory phenotypes of resting and interferon- gamma (IFN-gamma)-activated monocytes, unfractionated decidual cells, purified term decidual macrophages, and monocyte-derived macrophages. Surface markers for antigen presentation (HLA-DR, CD86), a membrane-bound cytokine interleukin (IL)-15, leukocyte immunoglobulin-like receptors (LILRB1, LILRB2), and secreted anti-inflammatory cytokines (transforming growth factor [TGF]-beta1 and IL-10) were assessed. The results demonstrate that differentiated, activated monocytes closely resemble but are not identical to decidual macrophages. In addition to differential IFN-gamma responsiveness, decidual macrophages were smaller than monocyte-derived macrophages and produced IL-10, which monocyte-derived macrophages did not. Only the unfractionated decidual cells secreted TGF-beta1. These results suggest that activation, differentiation, and decidual signals cooperate to program monocytes into the decidual macrophage phenotype.
