Increased Prevalence of Skeletal Anomalies on Ultrasound Evaluation of Buprenorphine-Exposed Human Fetuses.

Objectives: In this study, buprenorphine was the primary source of maternal opioid exposure at the time of initial prenatal evaluation. Current recommendations advise that level II ultrasounds be performed in patients with substance use disorders. For some patients, distance, transportation, and costs associated with obtaining ultrasounds from a specialist pose significant barriers.

A root nodule microbiome sequencing data set from red alder (Alnus rubra Bong.).

There have been frequent reports of more than one strain of the nitrogen-fixing symbiont, Frankia, in the same root nodule of plants in the genus Alnus, but quantitative assessments of their relative contributions have not been made to date. Neither has the diversity of other microbes, having potential functional roles in symbiosis, been systematically evaluated. Alnus rubra root nodule microbiota were studied using Illumina short read sequencing and kmer-based read classification.

Pathobiont-driven antibody sialylation through IL-10 undermines vaccination.

The pathobiont Staphylococcus aureus (Sa) induces nonprotective antibody imprints that underlie ineffective staphylococcal vaccination. However, the mechanism by which Sa modifies antibody activity is not clear. Herein, we demonstrate that IL-10 is the decisive factor that abrogates antibody protection in mice.

A Longitudinal Pediatric Residency Climate Justice Curriculum.

Graduate medical education programs must prepare physicians to adapt their care for patients whose health equity and outcomes are being threatened by climate change. This article presents the implementation of a longitudinal climate justice curriculum within a pediatrics residency program. To measure the self-reported changes in attitudes and intentions for change in behavior after implementation of a climate justice curriculum.

A 2-year calorie restriction intervention reduces glycomic biological age biomarkers.

Background/objective: In a subset of participants from the CALERIE Phase 2 study we evaluated the effects of 2y of ~25% Calorie Restriction (CR) diet on IgG N-glycosylation (GlycAge), plasma and complement C3 N-glycome as markers of aging and inflammaging.

Methods: Plasma samples from 26 participants in the CR group who completed the CALERIE2 trial and were deemed adherent to the intervention (~>10 % CR at 12 mo) were obtained from the NIA AgingResearchBiobank. Glycomic investigations using UPLC or LC-MS analyses were conducted on samples from baseline (BL), mid-intervention (12 mo) and post-intervention (24 mo), and changes resulting from the 2y CR intervention were examined.
