Improving the accuracy of reporting Ki-67 IHC by using an AI tool.

Ki-67 proliferative index (PI) scoring is measured by estimating the proportion of the number of active cell nuclei in hotspot regions within immunohistochemical (IHC) stained slides. It provides valuable information about the rate of proliferation in a tumour. Manual scoring of Ki-67 PI is laborious, time-consuming and often the victim of interobserver variability between pathologists.

Refined ELN 2024 risk stratification improves survival prognostication following venetoclax-based therapy in AML.

The European LeukemiaNet 2024 risk-stratification guidelines for patients with acute myeloid leukemia receiving hypomethylating agents combined with venetoclax were recently published. This analysis demonstrates reclassification and incorporation of new gene mutations in the present model can further improve and individualize prognostication.

Imposing vs finding unity.

The target article argues that embodied cognitive neuroscience converges on a mechanistic approach to explanation. We argue that it does not. Even some of the article's for embodied cognitive neuroscience are explicitly non- or anti-mechanistic.

Inflammation-induced epigenetic imprinting regulates intestinal stem cells.

It remains unknown whether and how intestinal stem cells (ISCs) adapt to inflammatory exposure and whether the adaptation leaves scars that will affect their subsequent regeneration. We investigated the consequences of inflammation on Lgr5 ISCs in well-defined clinically relevant models of acute gastrointestinal graft-versus-host disease (GI GVHD). Utilizing single-cell transcriptomics, as well as organoid, metabolic, epigenomic, and in vivo models, we found that Lgr5 ISCs undergo metabolic changes that lead to the accumulation of succinate, which reprograms their epigenome.
