[Comment] Colonoscopy, Cancer Prevention, and the New Arithmetic of Benefit
Colonoscopy has long been hailed as the gold‑standard for colorectal cancer screening, with observational studies suggesting it cuts incidence and mortality by at least 50%. The 13‑year follow‑up of the NordICC randomised trial, however, shows a modest 18% reduction in cancer incidence and a 30% drop in mortality, prompting a reassessment of its population‑level impact. The commentary by Aasma Shaukat argues that these findings demand a new arithmetic for weighing colonoscopy against other preventive tools. It also highlights how adherence rates shape real‑world outcomes.
Special Packaging Enables Effective Mitochondrial Delivery
Researchers have engineered "mito‑capsules" by wrapping donor mitochondria in erythrocyte‑derived plasma membranes, a technique that markedly improves delivery and integration into recipient cells.
