Anemia is an etiologically heterogeneous condition affecting over half of preschool-aged children in South Asia. An urgent need exists to elucidate context-specific causes of anemia to effectively address this issue.

This study investigated national trends and stability in the prevalence of child anemia and associated risk factors from 2013 to 2016 in Nepal.

Same-season national surveys were administered in 2013, 2014, and 2016 in 63 sites across 21 districts, selected using multistage random sampling, representing the mountains, hills, and Tarai (plains). Among consenting households with children aged 6-59 mo, a random sample of capillary blood was selected each year for anemia assessment using an Hb 201+ hemoglobinometer, with
=835, 807, and 881 children assessed, respectively. Prevalence of child anemia, defined as hemoglobin <11.0g/dL with adjustment for altitude, was estimated each year and disaggregated by region and child age. Prevalence ratios were estimated using log-binomial regression mo, and improving maternal and child health.
Anemia affects more than half of Nepalese children aged 6-59 mo. Although prevalence varies year to year, the stability of observed risk factors suggests the need to focus on reducing gastrointestinal infection, promoting adequate household sanitation, and improving maternal and child health.Responsive feeding (RF) involves reciprocal nurturing feeding practices between the caregiver and the child that encourage the child to develop preferences for healthy foods and beverages and to eat autonomously. In this commentary, we summarize RF-related findings from a recent US National Academies of Sciences, Engineering, and Medicine (National Academies) consensus study report examining consistency in infant and young child feeding (IYCF) recommendations in guidelines from high-income countries, and we discuss implications for future IYCF guidelines. Although existing guidelines included generally consistent messages about several RF behaviors, such as the importance of encouraging self-feeding and self-regulation in infants and toddlers, they generally did not present the recommendations as part of a cohesive RF interdisciplinary framework. Moving forward, evidence-based RF recommendations should be routinely incorporated and identified in dietary guidance for IYCF based on a consensus definition of RF grounded in sound responsive parenting and feeding frameworks. We recommend replicating the National Academies' scoping review in low- and middle- income countries and mixed-methods implementation science research to improve our understanding of how best to disseminate and implement RF-related recommendations across settings (e.g., home and early care and education centers), taking the social determinants of health into account.
Evidence documenting whether diet quality, particularly dietary fatty acids, is associated with preterm birth (PTB) is limited.

The aim was to measure associations between dietary fatty acid intake prior to pregnancy, specifically n-3 (ɷ-3) PUFAs and odds of PTB in US women and determine if associations differed by prepregnancy BMI.

We designed a secondary analysis of dietary intake in nulliparous women enrolled in a longitudinal cohort (NCT01322529). Participants completed an FFQ, modified to assess detailed PUFA intake, during the 3 mo preceding pregnancy. Inclusion in this analytic cohort required total energy intake within 2 SDs of the group mean. Prepregnancy BMI was categorized as underweight, normal, overweight, or obese. The primary exposure was estimated intake of EPA and DHA (combined EPA+DHA), in the context of a recommended intake of 250 mg. 2-APV in vitro The primary outcome was PTB (<37 wk). Adjusted regression models controlled for maternal factors relevant to PTB and evaluated associations with PUFAictors of adverse pregnancy outcomes, dietary intake of combined EPA+DHA was considerably lower than recommended. Associations between intake of these recommended n-3 fatty acids and risk of PTB differ by maternal BMI.
α-Tocopherol (αT) is essential for fetal development. One study has shown that the human placenta preferentially transfers the natural stereoisomer,
-αT. But prenatal supplements generally contain synthetic αT (S-αT).

We aimed to determine if umbilical cord plasma is enriched for
-αT in racially diverse neonates from both uncomplicated and complicated pregnancies and if cord
-αT enrichment is impacted by maternal αT stereoisomer profile.

We measured αT and αT stereoisomers in plasma from a randomly selected subset of 66 predominantly black and Hispanic maternal-fetal pairs from the Camden Study involving control (
=28) and complicated pregnancies (
=38). We collected maternal plasma at study entry (week 16 gestation; w16) and week 28 gestation (w28) and cord plasma at birth.

-αT was the predominant stereoisomer in all maternal and cord plasma samples, but S-αT stereoisomers were found in most samples and comprised a high percentage of αT in some maternal-neonate pairs. Cord plasma had a higher.
The proportion of RRR-αT was higher in cord compared with maternal plasma in both uncomplicated and complicated pregnancies. Our data suggest that maternal S-αT raises cord S-αT and decreases the proportion of RRR-αT in the neonatal circulation. Because the bioactivities of RRR-αT and S-αT differ, this warrants future research to determine the importance of our observations to neonatal αT status.[This corrects the article DOI 10.1063/5.0030534.].Coronary in-stent restenosis and late stent thrombosis are the two major inadequacies of vascular stents that limit its long-term efficacy. Although restenosis has been successfully inhibited through the use of the current clinical drug-eluting stent which releases antiproliferative drugs, problems of late-stent thrombosis remain a concern due to polymer hypersensitivity and delayed re-endothelialization. Thus, the field of coronary stenting demands devices having enhanced compatibility and effectiveness to endothelial cells. Nanotechnology allows for efficient modulation of surface roughness, chemistry, feature size, and drug/biologics loading, to attain the desired biological response. Hence, surface topographical modification at the nanoscale is a plausible strategy to improve stent performance by utilizing novel design schemes that incorporate nanofeatures via the use of nanostructures, particles, or fibers, with or without the use of drugs/biologics. The main intent of this review is to deliberate on the impact of nanotechnology approaches for stent design and development and the recent advancements in this field on vascular stent performance.
