United States and European Union laws demand separate clinical studies in children as a condition for drugs' marketing approval. Justified by carefully framed pseudo-scientific wordings, more so the European Medicines Agency than the United States Food and Drug Administration, "Pediatric Drug Development" is probably the largest abuse in medical research in history. Preterm newborns are immature and vulnerable, but they grow.

Human tumors are diverse in their natural history and response to treatment, which in part results from genetic and transcriptomic heterogeneity. In clinical practice, single-site needle biopsies are used to sample this diversity, but cancer biomarkers may be confounded by spatiogenomic heterogeneity within individual tumors. Here we investigate clonally expressed genes as a solution to the sampling bias problem by analyzing multiregion whole-exome and RNA sequencing data for 450 tumor regions from 184 patients with lung adenocarcinoma in the TRACERx study.

This report presents findings from a group of UK-based researchers with expertise in the use of animal models for bone marrow ablation and reconstitution. The primary aim is to facilitate the implementation of the Three Rs (Replacement, Reduction and Refinement), with an emphasis on refinement. Bone marrow ablation and reconstitution procedures are performed for a number of different purposes and conducted predominantly in mice.

Background: Aspirin has proved its efficacy in reducing the rate of preeclampsia in singleton pregnancy, however, there is discrepancy about the efficient dosage that should be used. While some societies recommend daily 75-81mg, others recommend higher dosage (160mg). This discrepancy is due to the lack of randomized controlled studies that compare these two dosages.

Background: Infliximab and adalimumab are the only biologics thus far approved for paediatric patients with inflammatory bowel disease (IBD), so other biologics, such as vedolizumab, are prescribed off-label. Despite its frequent use, prospective data for vedolizumab treatment in children are available only for short-term induction outcomes. We aimed to evaluate the long-term efficacy and safety of maintenance therapy with vedolizumab in paediatric patients with IBD.
