Background: Anemia during pregnancy may be associated with poor infant outcomes, although its consequences may vary based on etiology and timing.

Objectives: We examined the associations between anemia and anemia-related biomarkers during pregnancy and infant outcomes [birthweight, gestational age at birth, birthweight-for-gestational age percentile, and infant hemoglobin (Hb) at 6 wk of age] in Nagpur, Eastern Maharashtra, India.

Methods: We conducted a prospective cohort study of 200 pregnant women.

Markers of Environmental Enteric Dysfunction are Associated with Poor Growth and Developmental Outcomes among Young Children in Lusaka, Zambia.

Objective: To examine cross-sectional relationships between biomarkers of environmental enteric dysfunction (EED), an acquired subclinical condition of the small intestine, and anthropometric and developmental outcomes among children in Lusaka, Zambia.

Study Design: Serum samples were collected from 240 children aged 27 to 35 months enrolled in a cluster-randomized trial assessing the effects of growth charts and small-quantity lipid-based nutrient supplements on linear growth. Samples were analyzed using the 11-plex Micronutrient and EED Assessment Tool, which incorporates 2 biomarkers of EED, namely intestinal fatty acid-binding protein (I-FABP), a marker of epithelial damage, and soluble CD14 (sCD14), a marker of microbial translocation.

Predictors of Stunting and Pathway Analysis for Linear Growth among Children Aged Two to Three Years after a Trial of Small-Quantity Lipid-Based Nutrient Supplements and Home-Installed Growth Charts in Three Districts in Zambia.

Background: Globally, 148 million children aged <5 y are stunted, with risk factors varying by context. Our "Impact of Growth Charts and Nutritional Supplements on Child Growth in Zambia" (ZamCharts) trial observed persistently high rates of stunting in all treatment groups after 18-mo of intervention with monthly distributions of small-quantity lipid-based nutrient supplements (SQ-LNS) and/or installation of a wall-mounted growth chart in children's homes.

Objectives: We sought to identify determinants of stunting and height-for-age z-score in children aged 27-36 mo who participated in the ZamCharts endline survey (n = 1911).

This scoping review aims to synthesise the evidence of the impairments and disabilities in SA countries. This review followed Arksey and O'Malley's methodological framework.

Effects of Vitamin D-3 Supplementation During Pregnancy and Lactation on Maternal and Infant Biomarkers of Environmental Enteric Dysfunction, Systemic Inflammation, and Growth: A Secondary Analysis of a Randomized Controlled Trial.

Background: Environmental enteric dysfunction (EED) is an acquired, subclinical state of intestinal inflammation common in children and adults in low-income and middle-income countries. Although vitamin D-3 supplementation has purported anti-inflammatory properties, its ability to ameliorate biomarkers of EED remains unclear.

Objectives: This study aimed to examine the effects of maternal vitamin D-3 supplementation during pregnancy and lactation on biomarkers of EED, systemic inflammation, and growth in women living with HIV and their infants in Dar es Salaam, Tanzania.

Simple Methodology to Score Micropattern Quality and Effectiveness.

Micropatterns (MPs) are widely used as a powerful tool to control cell morphology and phenotype. However, methods for determining the effectiveness of how well cells are controlled by the shape of MPs have been inconsistently used and studies rarely report on this topic, indicating lack of standardization. We introduce an evaluation score that quantitatively assesses the MP fabrication quality and effectiveness, which can be broadly used in conjunction with all currently available MP design types.

The impact of home-installed growth charts and small-quantity lipid-based nutrient supplements (SQ-LNS) on child growth in Zambia: a four-arm parallel open-label cluster randomised controlled trial.

Background: Childhood stunting remains common in many low-income settings and is associated with increased morbidity and mortality, as well as impaired child development.

Methods: The main objective of the study was to assess whether home-installed growth charts as well as small-quantity lipid-based nutrient supplements (SQ-LNS) can reduce growth faltering among infants. All caregivers of infants between 2 and 10 months of age at baseline, and at least 6 months old at the beginning of the interventions, in 282 randomly selected enumeration areas in Choma, Mansa and Lusaka districts in Zambia were invited to participate in the study.

Visualizing Black Telephone Users: Technological Whiteness and Racial Exclusion in Bell System Advertising.

This study considers the broad implications of white technological modernity as a mode of symbolic and systemic exclusion. The visual absence of Black telephone users in mass-market advertising-and the struggle to make them visible-underscores the exclusionary power of technological whiteness and its lasting effects on conceptions of Black technology users, communities, and innovation. In the first half of the twentieth century, American Telephone and Telegraph (AT&T) tirelessly promoted its national telephone network as a model of technological progress and universal service, but this vision did not include African Americans.

The prevalence of anemia during pregnancy and its correlates vary by trimester and hemoglobin assessment method in Eastern Maharashtra, India.

Approximately half of pregnant women in India are anemic, representing over 7.5 million women. Few studies have assessed the relationship between multiple micronutrient deficiencies and anemia during pregnancy or the trajectory of hemoglobin (Hb) during pregnancy in low-resource settings.

SuperAnimal pretrained pose estimation models for behavioral analysis.

Quantification of behavior is critical in diverse applications from neuroscience, veterinary medicine to animal conservation. A common key step for behavioral analysis is first extracting relevant keypoints on animals, known as pose estimation. However, reliable inference of poses currently requires domain knowledge and manual labeling effort to build supervised models.

The Full Value of Vaccine Assessments Concept-Current Opportunities and Recommendations.

For vaccine development and adoption decisions, the 'Full Value of Vaccine Assessment' (FVVA) framework has been proposed by the WHO to expand the range of evidence available to support the prioritization of candidate vaccines for investment and eventual uptake by low- and middle-income countries. Recent applications of the FVVA framework have already shown benefits. Building on the success of these applications, we see important new opportunities to maximize the future utility of FVVAs to country and global stakeholders and provide a proof-of-concept for analyses in other areas of disease control and prevention.

Effects of Zinc Supplementation on Metabolomic Profiles in Tanzanian Infants: A Randomized Trial.

Background: Provision of zinc supplementation to young children has been associated with reduced infectious morbidity and better growth outcomes. However, the metabolic pathways underlying these outcomes are unclear, and metabolomic data from humans undergoing zinc supplementation, particularly infants, are generally lacking.

Objectives: This study aimed to examine the effect of zinc supplementation on metabolic profiles in Tanzanian infants aged 6 wk and 6 mo.

Greenhouse gas emissions from soils in corn-based cropping systems.

Crop rotation is a management practice with high greenhouse gas (GHG) mitigating potential that is often neglected due to economic influences. Three long-term rotation studies in Wisconsin were selected to assess the potential opportunities for mitigating GHG emissions by comparing the temporal and spatial variability of N O, CO , and CH emissions in continuous corn (CC) (Zea mays L.), corn-soybean (CS) [Glycine max (L.

Therapeutic Modulation of Cell Morphology and Phenotype of Diseased Human Cells towards a Healthier Cell State Using Lignin.

Despite lignin's global abundance and its use in biomedical studies, our understanding of how lignin regulates disease through modulation of cell morphology and associated phenotype of human cells is unknown. We combined an automated high-throughput image cell segmentation technique for quantitatively measuring a panel of cell shape descriptors, droplet digital Polymerase Chain Reaction for absolute quantification of gene expression and multivariate data analyses to determine whether lignin could therapeutically modulate the cell morphology and phenotype of inflamed, degenerating diseased human cells (osteoarthritic (OA) chondrocytes) towards a healthier cell morphology and phenotype. Lignin dose-dependently modified all aspects of cell morphology and ameliorated the diseased shape of OA chondrocytes by inducing a less fibroblastic healthier cell shape, which correlated with the downregulation of collagen 1A2 (COL1A2, a major fibrosis-inducing gene), upregulation of collagen 2A1 (COL2A1, a healthy extracellular matrix-inducing gene) and downregulation of interleukin-6 (IL-6, a chronic inflammatory cytokine).

The Full Value of Vaccine Assessments (FVVA): a framework for assessing and communicating the value of vaccines for investment and introduction decision-making.

Background: Several economic obstacles can deter the development and use of vaccines. This can lead to limited product options for some diseases, delays in new product development, and inequitable access to vaccines. Although seemingly distinct, these obstacles are actually interrelated and therefore need to be addressed through a single over-arching strategy encompassing all stakeholders.

Structural basis of mRNA binding by the human FERRY Rab5 effector complex.

The pentameric FERRY Rab5 effector complex is a molecular link between mRNA and early endosomes in mRNA intracellular distribution. Here, we determine the cryo-EM structure of human FERRY. It reveals a unique clamp-like architecture that bears no resemblance to any known structure of Rab effectors.

Video-driven simulation of lower limb mechanical loading during aquatic exercises.

Understanding the mechanical demands of an exercise on the musculoskeletal system is crucial to prescribe effective training or therapeutic interventions. Yet, that knowledge is currently limited in water, mostly because of the difficulty in evaluating external resistance. Here I reconcile recent advances in 3D markerless pose and mesh estimation, biomechanical simulations, and hydrodynamic modeling, to predict lower limb mechanical loading during aquatic exercises.
