Prenatal polycyclic aromatic hydrocarbons exposure and child growth and adiposity: A longitudinal study.

Background: Exposure to polycyclic aromatic hydrocarbons (PAHs) during childhood has been associated with altered growth and adiposity in children. The effects of prenatal exposure to PAHs on developmental programming of growth and adiposity are still unknown.

Objective: To study the association of prenatal exposure to PAHs with early childhood growth and adiposity measures.

Localized inflammation in dengue vaccine-induced skin rash is not associated with continuous presence of dengue virus genome.

Vaccination with the tetravalent live attenuated dengue virus (DENV) vaccines TV003 and TV005 causes a mild, relatively localized erythematous maculopapular skin rash in most dengue-naïve vaccinees. Human challenge model DENV strains, DENV2Δ30 and DENV3Δ30, trigger a confluent skin rash over most of the body in most unvaccinated participants. To determine the etiology of these rashes we performed in situ hybridization for DENV genome and assessed cellular infiltration by hematoxylin/eosin staining in skin biopsies from humans infected with live attenuated dengue vaccine DENV2Δ30 or DENV3Δ30 challenge strains.

Engineered myeloid precursors differentiate into osteoclasts and resorb heterotopic ossification in mice.

Introduction: Heterotopic ossification (HO) occurs following orthopedic trauma, spinal cord injuries, brain trauma and limb amputations. Once symptomatic, HO causes pain, limited mobility and decreased quality of life. Current treatments are limited and have significant complications with high recurrence rates, underscoring the need for improved therapeutic interventions.

The California collaborative network to promote data driven care and improve outcomes in early psychosis (EPI-CAL) project: rationale, background, design and methodology.

Background: A prolonged first episode of psychosis (FEP) without adequate treatment is a predictor of poor clinical, functional, and health outcomes and significant economic burden. Team-based "coordinated specialty care" (CSC) for early psychosis (EP) has established effectiveness in promoting clinical and functional recovery. However, California's CSC program implementation has been unsystematic and could benefit from standardizing its processes and data collection infrastructure.

Temporal and geographic variability of bisphenol levels in humans: A systematic review and meta-analysis of international biomonitoring data.

Introduction: Bisphenols are endocrine-disrupting chemicals known to contribute to chronic disease across the lifespan. With increased awareness of their health effects, changes in regulation and health behaviors have contributed to reductions in urinary bisphenol A (BPA) levels in the United States, Canada, and Europe. However, global trends in bisphenols outside these regions, especially bisphenol S (BPS) exposure, have been less studied.

Cell mediated reactions create TGF-β delivery limitations in engineered cartilage.

During native cartilage development, endogenous TGF-β activity is tightly regulated by cell-mediated chemical reactions in the extracellular milieu (e.g., matrix and receptor binding), providing spatiotemporal control in a manner that is localized and short acting.

Beyond the Spectrum: Subtype-Specific Molecular Insights into Autism Spectrum Disorder Via Multimodal Data Integration.

Some toddlers with autism spectrum disorder (ASD) have mild social symptoms and developmental improvement in skills, but for others, symptoms and abilities are moderately or even severely affected. Those with profound autism have the most severe social, language, and cognitive symptoms and are at the greatest risk of having a poor developmental outcome. The little that is known about the underlying biology of this important profound autism subtype, points clearly to embryonic dysregulation of proliferation, differentiation and neurogenesis.

Early Childhood Routines and Adolescent Health & Well-Being: Associations From a US Urban Cohort of Children With Socioeconomic Disadvantage.

Purpose: To investigate longitudinal associations between the presence of early childhood routines- predictable and repeatable functional practices that promote healthy growth, development, and relationships - and adolescent health outcomes.

Design: Secondary data analysis.

Setting: 20 large U.

Commensal consortia decolonize Enterobacteriaceae via ecological control.

Persistent colonization and outgrowth of potentially pathogenic organisms in the intestine can result from long-term antibiotic use or inflammatory conditions, and may perpetuate dysregulated immunity and tissue damage. Gram-negative Enterobacteriaceae gut pathobionts are particularly recalcitrant to conventional antibiotic treatment, although an emerging body of evidence suggests that manipulation of the commensal microbiota may be a practical alternative therapeutic strategy. Here we isolated and down-selected commensal bacterial consortia from stool samples from healthy humans that could strongly and specifically suppress intestinal Enterobacteriaceae.

Movement pattern definitions for resistance training behavior measurement in diabetes.

Type 2 diabetes can result in debilitating vascular complications, and resistance training (RT) is an effective therapy for improving cardiovascular outcomes. However, only 10-30% of adults meet the public health guidance for RT. While current RT guidelines focus on targeting major muscle groups, guidance specific to simplified movement categorization may augment understanding of RT programming and improve uptake and outcomes.

Magneto-Responsive Chiral Optical Materials: Flow-Induced Twisting of Cellulose Nanocrystals in Patterned Magnetic Fields.

Magnetic fields have been used to uniformly align the lyotropic chiral nematic (cholesteric) liquid crystalline (LC) phase of biopolymers to a global orientation and optical appearance. Here, we demonstrate that, in contrast, weak and patterned magnetic field gradients can create a complex optical appearance with the variable spatial local organization of needle-like magnetically decorated cellulose nanocrystals. The formation of optically patterned thin films with left- and right-handed chiral and achiral regions is observed and related to local magnetic gradient-driven vortices during LC suspension flow.

Point-of-Care Cardiac Troponin I Assay Evaluation in New Zealand White Rabbits (Oryctolagus cuniculus).

Cardiac troponin I (cTnI) is a cardiac-specific biomarker, used for the detection of myocardial injury. While rabbits develop naturally occurring cardiovascular disease, they are also an animal model for human disease; thus, rapid detection of cTnI has implications for both veterinary and human medicine. The objective of this study was to validate and establish a reference interval for a point-of-care (POC) cTnI assay in New Zealand White rabbits.

The glycolytic reaction PGAM unexpectedly restrains Th17 pathogenicity and Th17-dependent autoimmunity.

Glucose metabolism is a critical regulator of T cell function, largely thought to support their activation and effector differentiation. Here, we investigate the relevance of individual glycolytic reactions in determining the pathogenicity of T helper 17 (Th17) cells using single-cell RNA-seq and Compass, an algorithm we previously developed for estimating metabolic flux from single-cell transcriptomes. Surprisingly, Compass predicted that the metabolic shunt between 3-phosphoglycerate (3PG) and 2-phosphoglycerate (2PG) is inversely correlated with pathogenicity in these cells, whereas both its upstream and downstream reactions were positively correlated.

Fetal Right Heart Strain in Systemic Right Ventricles and Impact on Post-surgical Outcomes.

Patients with hypoplastic left heart syndrome (HLHS) and its variants rely on the right ventricle (RV) to provide cardiac output. Diminished RV systolic function has been associated with poor clinical outcomes in this population. Echocardiographic strain has emerged as a useful method to quantify RV deformation.

Physical performance and plasma metabolic profile as potential prognostic factors in metastatic lung cancer patients.

Background: Low physical performance is associated with higher mortality rate in multiple pathological conditions. Here, we aimed to determine whether body composition and physical performance could be prognostic factors in non-small cell lung cancer (NSCLC) patients. Moreover, we performed an exploratory approach to determine whether plasma samples from NSCLC patients could directly affect metabolic and structural phenotypes in primary muscle cells.

Trajectories of Housing Insecurity From Infancy to Adolescence and Adolescent Health Outcomes.

Background And Objectives: Housing insecurity is associated with adverse effects on child growth and development cross-sectionally; less is known about its cumulative, long-term effects. This study describes longitudinal experiences of housing insecurity during childhood from infancy (age 1 year) to adolescence (age 15 years) and examines their associations with adolescent health outcomes.

Methods: Using data from the Future of Families and Child Wellbeing Study, we created a composite measure of housing insecurity using 5 indicators (eg, skipping a rent or mortgage payment, eviction) for participants at ages 1, 3, 5, 9, and 15 years.
