Two Trials Comparing Conduction System Pacing and Biventricular Pacing
https://jamanetwork.com/journals/jamacardiology/fullarticle/2845804
Cardiac resynchronization therapy (CRT) with biventricular pacing (BiVP) remains a cornerstone treatment for patients with heart failure with reduced ejection fraction and left bundle-branch block (LBBB), supported by decades of randomized evidence demonstrating reductions in mortality and heart failure hospitalization. In parallel, conduction system pacing (CSP), most commonly delivered as left bundle-branch area pacing (LBBAP), has emerged as a physiologically appealing alternative, aiming to directly recruit the His-Purkinje system. Because early observational studies and small randomized trials reported superior electrical resynchronization and larger improvements in left ventricular ejection fraction (LVEF) with CSP than with BiVP, CSP is becoming increasingly popular for CRT in patients who have a strong indication for BiVP.

Biosimilar Competition in Oncology—Beyond Insurer Pressure
https://jamanetwork.com/journals/jama/fullarticle/2846348
The high price of drugs continues to be the focus of policy discussions, with attention often drawn to the importance of promoting price competition through the use of generic and biosimilar versions of branded reference products. As occurred with small-molecule drugs and generics after the passage of the Hatch-Waxman Act of 1984, the creation of a biosimilar approval pathway in the Affordable Care Act’s Biologics Price Competition and Innovation Act was intended to lower spending on biologic products after reference-product patents expire.

A Criticism of Modern Medicine
https://jamanetwork.com/journals/jama/fullarticle/2846423
A conscientious reviewer of the history of medicine would probably admit that within the last century, and largely within half that period, medical science and art have advanced with a speed incomparably greater than at any previous time. Philosophical speculation has given way to experimentation as medicine has kept pace with the advancement of science in general. It would be as ungracious as it is unjust to deny the great advance of medical knowledge along with the evolution of culture; and medicine can proudly boast of many conquests that deserve to be called marvelous.

ORCHESTRA Hits a Sour Note for Debulking in Metastatic Colorectal Cancer
https://jamanetwork.com/journals/jama/fullarticle/2846538
Colorectal cancer (CRC) remains one of the few solid tumors for which surgical intervention to remove limited metastatic disease has been associated with curative outcomes or improved overall survival. This has been demonstrated in liver-limited, lung-limited, and peritoneal-limited disease. Encouraging findings from hepatectomy in liver-limited disease led to extrapolation of resection to patients with multiple organ involvement in whom complete resection could be attained. Indeed, resection in patients with liver and lung metastases has been linked to favorable survival, as has resection in patients with peritoneal metastases with limited liver involvement. Although most patients undergoing curative resections have metastases recur, their median overall survival has typically been favorable compared with historic controls.

Clarifying the SOFA-2 Score
https://jamanetwork.com/journals/jama/fullarticle/2846536
To the Editor The SOFA-2 score is an important step toward improving the precision of organ dysfunction assessment in contemporary critical care. By redefining thresholds within its 6 organ domains using data-driven modeling, SOFA-2 enhances calibration and predictive performance in sepsis cohorts. However, its direct application to tropical infections such as dengue, scrub typhus, leptospirosis, and malaria warrants cautious interpretation. The physiological foundations of SOFA-2 are largely derived from bacterial sepsis, and certain domains, particularly hepatic and coagulation, may not fully capture the pathophysiological profiles seen in these infections.
