Prenatal Diagnosis of Congenital Heart Disease in Liveborn Infants in the New England Region.

Prenatal diagnosis of congenital heart disease requiring early cardiac catheterization or surgical intervention enables optimal delivery planning for appropriate postnatal cardiovascular intervention and care. This allows for improved morbidity and mortality. Prior national data reported prenatal diagnosis rates of 32% for congenital heart disease requiring intervention in infants in the first 6 months of life in the New England region.

Variable impacts of land-based climate mitigation on habitat area for vertebrate diversity.

Pathways to achieving net zero carbon emissions commonly involve deploying reforestation, afforestation, and bioenergy crops across millions of hectares of land. It is often assumed that by helping to mitigate climate change, these strategies indirectly benefit biodiversity. Here, we modeled the climate and habitat requirements of 14,234 vertebrate species and show that the impact of these strategies on species' habitat area tends not to arise through climate mitigation, but rather through habitat conversion.

Chemical signals and social structures strengthen sexual isolation in Drosophila pseudoobscura.

Species that coexist in hybrid zones sexually isolate through reproductive character displacement, a mechanism that favours divergence between species. In Drosophila, behavioural and physiological traits discourage heterospecific mating between species. Recently, social network analysis revealed flies produce strain-specific and species-specific social structures.

Baseline Drug Clearance Predicts Outcomes in Children With Inflammatory Bowel Disease Treated With Vedolizumab: Results From the VedoKids Prospective Multicentre Study.

Background: The pharmacokinetics of biologic agents can differ between children and adults with inflammatory bowel disease (IBD), often necessitating modified paediatric dosing strategies.

Aims: To define the exposure-response relationship of vedolizumab in the paediatric IBD VedoKids cohort including the effect of baseline clearance on deep biochemical remission (normal C-reactive protein [CRP]/erythrocyte sedimentation rate [ESR] and steroid-free remission) at 30 weeks, and to use population pharmacokinetic models to find the best matches between adult and paediatric pharmacokinetic profiles.

Methods: We sought a pharmacokinetic model on 312 serum vedolizumab concentrations from 129 children, assisted by a published adult model as a Bayesian prior.
