Single‐Cell and Spatial Analysis Reveal the Differences Between Left‐Sided and Right‐Sided Colorectal Cancer

Cell Proliferation, EarlyView.
Single‐cell and spatial analysis revealed distinct CRC microenvironments by tumour laterality. Right‐sided tumours showed enhanced germinal centre B cells, CXCL13+ T cells, and organized TLS‐immune crosstalk via CCL19/21‐CCR7, suggesting better immunotherapy response.

Prepackaged Low‐Residue Diet “Clear‐Through” Reduces the Required Volume of Polyethylene Glycol Solution for Colonoscopy Preparation: An Exploratory Randomized Controlled Study

DEN Open, Volume 7, Issue 1, April 2027.
ABSTRACT Objectives Large volumes of polyethylene glycol (PEG) solution reduce patient acceptance of colonoscopy. A prepackaged low‐residue diet (PLRD; Clear‐Through) may improve bowel cleansing and allow further PEG reduction. This exploratory randomized study evaluated whether PLRD permits decreased PEG with ascorbic acid (PEG‐Asc) volume while ...
