Maternal hemoglobin A1c and left ventricular hypertrophy in infants of mothers with pre-gestational diabetes.

Objective: Maternal hemoglobin A1c (HbA1c) has been suggested to be a predictor of left ventricular hypertrophy (LVH) in the offspring of mothers with pre-gestational diabetes mellitus, although there is little data supporting this contention. We aimed to assess the relationship between maternal HbA1c and postnatal LVH.

Methods: We performed a retrospective cohort study of infants born to mothers with pre-gestational diabetes mellitus from 2015 to 2021 at our institution.

One-food versus 4-food elimination diet for pediatric eosinophilic esophagitis: A multisite randomized trial.

Background: A 6-food elimination diet in pediatric eosinophilic esophagitis (EoE) is difficult to implement and may negatively affect quality of life (QoL). Less restrictive elimination diets may balance QoL and efficacy.

Objective: We performed a multisite, randomized comparative efficacy trial of a 1-food (milk) elimination diet (1FED) versus 4-food (milk, egg, wheat, soy) elimination diet (4FED) in pediatric EoE.

Exploring the relationship between child temperament, maternal psychiatric symptoms, family environment and infant feeding.

Objectives: Infant temperament is assumed to be primarily innate. However, newer research suggests that maternal affection impacts ratings of temperament and environmental factors, including feeding method, can also influence infant temperament. This study investigates child temperament and its relationships with maternal psychiatric symptoms, environmental variables and feeding method longitudinally in a cohort of children followed from 6 to 72 months.

Racial/Ethnic Differences in the Age-Varying Association Between Adherence to 8-5-2-1-0 Guidelines in Adolescents with High BMI.

Purpose: To examine the association between adherence to sleep, dietary, screen time, and physical activity (PA) (8-5-2-1-0) guidelines and risk of high body mass index (BMI ≥ 85 percentile) among U.S. adolescents and to assess for racial inequities and age-varying effects in these associations.

Maternal immune cell gene expression associates with maternal gut microbiome, milk composition and infant gut microbiome.

Background: Pre-pregnancy overweight and obesity promote deleterious health impacts on both mothers during pregnancy and the offspring. Significant changes in the maternal peripheral blood mononuclear cells (PBMCs) gene expression due to obesity are well-known. However, the impact of pre-pregnancy overweight on immune cell gene expression during pregnancy and its association with maternal and infant outcomes is not well explored.

Unraveling Protein-Metabolite Interactions in Precision Nutrition: A Case Study of Blueberry-Derived Metabolites Using Advanced Computational Methods.

Metabolomics, the study of small-molecule metabolites within biological systems, has become a potent instrument for understanding cellular processes. Despite its profound insights into health, disease, and drug development, identifying the protein partners for metabolites, especially dietary phytochemicals, remains challenging. In the present study, we introduced an innovative in silico, structure-based target prediction approach to efficiently predict protein targets for metabolites.

Childhood cardiometabolic risk factors associated with the perinatal environment of the maternal-paternal-child triad.

Introduction: Clustering of cardiometabolic risk factors in childhood significantly increases the risk of atherosclerotic cardiovascular disease later in life. Identification of modifiable parental factors that contribute to offspring cardiometabolic health is critical for the prevention of disease. The objective was to identify factors associated with child cardiometabolic risk factors at age 5 years.

Novel odd-chain cyclopropane fatty acids: detection in a mammalian lipidome and uptake by hepatosplanchnic tissues.

Microbe-produced molecules (xenometabolites) found in foods or produced by gut microbiota are increasingly implicated in microbe-microbe and microbe-host communication. Xenolipids, in particular, are a class of metabolites for which the full catalog remains to be elaborated in mammalian systems. We and others have observed that cis-3,4-methylene-heptanoylcarnitine is a lipid derivative that is one of the most abundant medium-chain acylcarnitines in human blood, hypothesized to be a product of incomplete β-oxidation of one or more "odd-chain" long-chain cyclopropane fatty acids (CpFAs).

Human quad liver-on-chip system as a tool toward bridging the gap between animals and humans regarding toxicology and pharmacology of a cannabidiol-rich cannabis extract.

Cannabidiol (CBD) is a major phytocannabinoid from . It is currently widely available and widely used in the USA, but despite its rapid progress to market, the pharmacology and toxicology of both CBD and cannabidiol-rich cannabis extracts (CRCE) remain largely unknown. The goals of this study were to investigate the potential of a novel human microphysiological system to emulate CRCE-induced hepatotoxicity and pharmacological properties demonstrated in animal models.

Western Diet Modifies Platelet Activation Profiles in Male Mice.

The correlation between obesity and cardiovascular disease has long been understood, yet scant investigations endeavored to determine the impact of an obesogenic diet on platelet activation or function. As platelets drive clot formation, the terminus of cardiovascular events, we aimed to elucidate the longitudinal effect of an obesogenic diet on platelet phenotype by assessing markers of platelet activation using flow cytometry. Male, weanling mice were fed either a Western diet (30% kcal sucrose, 40% kcal fat, 8.

Infant Microbiota Communities and Human Milk Oligosaccharide Supplementation Independently and Synergistically Shape Metabolite Production and Immune Responses in Healthy Mice.

Background: Multiple studies have demonstrated associations between the early-life gut microbiome and incidence of inflammatory and autoimmune disease in childhood. Although microbial colonization is necessary for proper immune education, it is not well understood at a mechanistic level how specific communities of bacteria promote immune maturation or drive immune dysfunction in infancy.

Objectives: In this study, we aimed to assess whether infant microbial communities with different overall structures differentially influence immune and gastrointestinal development in healthy mice.

Assessing the acceptability of a culturally adapted group-based pediatric intervention, Kokajjiriri, for Marshallese mothers and infants to improve nutrition and prevent childhood obesity.

Background: Marshallese Pacific Islanders experience higher rates of obesity than other racial and/or ethnic communities. Despite the obesity rates experienced in this community, there are currently no childhood obesity prevention interventions designed for Marshallese Pacific Islanders in the United States. The purpose of this study is to assess the acceptability and feasibility of a culturally adapted group-based pediatric intervention, Kokajjiriri, with Marshallese mothers to improve nutrition and reduce childhood obesity.

Toward a science-based classification of processed foods to support meaningful research and effective health policies.

Processed foods have been part of the American diet for decades, with key roles in providing a safe, available, affordable, and nutritious food supply. The USDA Food Guides beginning in 1916 and the US Dietary Guidelines for Americans (DGA) since 1980 have included various types of commonly consumed processed foods (e.g.

Klotho enhances diastolic function in aged hearts through Sirt1-mediated pathways.

Aging leads to a progressive decline in cardiac function, increasing the risk of heart failure with preserved ejection fraction (HFpEF). This study elucidates the impact of α-Klotho, an anti-aging hormone, on cardiac diastolic dysfunction and explore its downstream mechanisms. Aged wild-type and heterozygous Klotho-deficient mice received daily injection of soluble α-Klotho (sKL) for 10 weeks, followed by a comprehensive assessment of heart function by echocardiography, intracardiac pressure catheter, exercise tolerance, and cardiac pathology.

Delivering Telegenetics Services: Review and Synthesis of Best Practices.

Before the COVID-19 public health emergency, few genetics providers used telehealth. As a response to this, many genetics providers began conducting telehealth care, referred to as telegenetics, usually with guidance from their institutions but without specific guidance related to the uniqueness of genetic services. The Telegenetics Workgroup of the National Coordinating Center for Regional Genetics Networks convened a panel of experts in the fields of telemedicine, genetics, and genomics to review the existing literature on telegenetics and synthesize best operating practices for medical geneticists, genetic counselors, and metabolic dietitians providing telegenetics services.

The rRNA epitranscriptome and myonuclear SNORD landscape in skeletal muscle fibers contributes to ribosome heterogeneity and is altered by a hypertrophic stimulus.

In cell biology, ribosomal RNA (rRNA) 2'-methyl (2'--Me) is the most prevalent posttranscriptional chemical modification contributing to ribosome heterogeneity. The modification involves a family of small nucleolar RNAs (snoRNAs) and is specified by box C/D snoRNAs (SNORDs). Given the importance of ribosome biogenesis for skeletal muscle growth, we asked if rRNA 2'--Me in nascent ribosomes synthesized in response to a growth stimulus is an unrecognized mode of ribosome heterogeneity in muscle.

A Systematic Review over the Effect of Early Infant Diet on Neurodevelopment: Insights from Neuroimaging.

The optimization of infant neuronal development through nutrition is an increasingly studied area. While human milk consumption during infancy is thought to give a slight cognitive advantage throughout early childhood in comparison to commercial formula, the biological underpinnings of this process are less well-known and debated in the literature. This systematic review seeks to quantitatively analyze whether early diet affects infant neurodevelopment as measured by various neuroimaging modalities and techniques.

Grape and grape derived products contain many bioactive phenolics which have a variety of impacts on health. Following oral ingestion, the phenolic compounds and their metabolites may be detectable in human urine. However, developing a reliable method for the analysis of phenolic compounds in urine is challenging.

and carbohydrate active enzymes contribute to the reduced fat deposition in pigs.

Pig gastrointestinal tracts harbor a heterogeneous and dynamic ecosystem populated with trillions of microbes, enhancing the ability of the host to harvest energy from dietary carbohydrates and contributing to host adipogenesis and fatness. However, the microbial community structure and related mechanisms responsible for the differences between the fatty phenotypes and the lean phenotypes of the pigs remained to be comprehensively elucidated. Herein, we first found significant differences in microbial composition and potential functional capacity among different gut locations in Jinhua pigs with distinct fatness phenotypes.

Benefits of calorie restriction in mice are mediated via energy imbalance, not absolute energy or protein intake.

Caloric restriction (CR) results in reduced energy and protein intake, raising questions about protein restriction's contribution to CR longevity benefits. We kept ad libitum (AL)-fed male C57BL/6J mice at 27°C (AL27) and pair-fed (PF) mice at 22°C (22(PF27)). The 22(PF27) group was fed to match AL27 while restricted for calories due to cold-induced metabolism.
