NEJM studies: tricuspid repair wins, MCED screening falls short, sepsis fluids equal, optogenetic vision gains
Start here
Four studies published by the NEJM on 8 October 2026, reviewed by NEJM Group experts a week later, span cardiology, cancer screening, critical care and gene therapy. Transcatheter edge-to-edge repair plus medication outperformed medication alone in 360 patients with symptomatic severe tricuspid regurgitation on 1-year and 3-year composite endpoints. Three rounds of multicancer early detection blood testing plus usual care did not reduce stage III/IV incidence of 12 preset cancers compared with usual care alone in adults aged 50 to 77. In emergency-department septic shock, restrictive fluids with early vasopressors matched high-volume fluids on 90-day days alive out of hospital. Optogenetic AAV therapy gave clinically meaningful light perception improvement in 6 of 10 blind retinitis pigmentosa patients.

A NEJM Group expert review covers studies from 8 October 2026. Transcatheter edge-to-edge repair plus medication beat medication alone in 360 patients with symptomatic severe tricuspid regurgitation on 1-year and 3-year composite endpoints; three rounds of MCED blood testing plus usual care did not reduce stage III/IV incidence of 12 preset cancers versus usual care alone in adults aged 50 to 77; restrictive fluids with early vasopressors matched high-volume fluids on 90-day days alive out of hospital in emergency septic shock; and optogenetic AAV therapy gave clinically meaningful light perception improvement in 6 of 10 blind retinitis pigmentosa patients.
