Unnecessary Scans Lead to Unnecessary Re-scans: Evaluating Clinical Management of Low and Intermediate Risk Pediatric Traumatic Brain Injuries.

Background: The Pediatric Emergency Care Applied Research Network (PECARN) guidelines provide an algorithm to select patients with mild head trauma at highest risk for clinically important traumatic brain injury (ciTBI) in whom computed tomography (CT) would facilitate management. Failure to follow PECARN criteria exposes children to unnecessary radiation and contributes to increasing hospital costs, length of stay, and parental anxiety. We sought to evaluate the subsequent allocation of resources to low and intermediate risk group patients who underwent an initial Head CT - which was not indicated by PECARN guidelines but which identified cranial or intracranial injury.

Adaptive gene loss in the common bean pan-genome during range expansion and domestication.

The common bean (Phaseolus vulgaris L.) is a crucial legume crop and an ideal evolutionary model to study adaptive diversity in wild and domesticated populations. Here, we present a common bean pan-genome based on five high-quality genomes and whole-genome reads representing 339 genotypes.

Natural selection drives emergent genetic homogeneity in a century-scale experiment with barley.

Direct observation is central to our understanding of adaptation, but evolution is rarely documented in a large, multicellular organism for more than a few generations. In this study, we observed evolution across a century-scale competition experiment, barley composite cross II (CCII). CCII was founded in 1929 in Davis, California, with thousands of genotypes, but we found that natural selection has massively reduced genetic diversity, leading to a single lineage constituting most of the population by generation 50.

UDP-glucosyltransferase HvUGT13248 confers type II resistance to Fusarium graminearum in barley.

Fusarium head blight (FHB) of barley (Hordeum vulgare) causes yield losses and accumulation of trichothecene mycotoxins (e.g. deoxynivalenol [DON]) in grains.
