We compared SWE with vibration-controlled transient elastography (VCTE) using American Gastroenterological Association (AGA) and European Association for the Study of the Liver (EASL) algorithms. Approach &amp; Results: Patients with MASLD who underwent both VCTE and SWE during the same session between 2019 and 2025 were included. Risk stratification was performed using AGA- and EASL-based two-step approaches. The primary endpoint was liver-related events (LRE). Among 2,817 patients, the AGA-SWE algorithm classified 2,196, 140, and 481 patients as low-, intermediate-, and high-risk, respectively. Using the AGA-SWE algorithm, both intermediate- and high-risk groups showed increased risks of LREs compared with the low-risk group (subdistribution hazard ratio [sHR] 7.60 and 9.86, respectively). The EASL-SWE algorithm also stratified LRE risk relative to the low-risk group, with higher sHRs observed for the intermediate-low, intermediate-high, and high-risk groups (sHR 2.99, 10.83, and 18.87, respectively). The integrated time-dependent area under the curve through 60 months was 0.770 (95% confidence interval [CI]: 0.709, 0.827) and 0.775 (95% CI: 0.712, 0.835) for AGA-SWE and AGA-VCTE, respectively, and 0.804 (95% CI: 0.753, 0.849) and 0.805 (95% CI: 0.750, 0.852) for EASL-SWE and EASL-VCTE, respectively, with no significant differences between SWE and VCTE in either algorithm. No significant net reclassification improvement was observed between SWE- and VCTE-based AGA algorithms.

The RNA-binding protein hnRNPK is critical for hepatic homeostasis, but its role in chronic fibrosis remains undefined. This study investigated hnRNPK-mediated splicing dysregulation in liver fibrosis and its therapeutic potential. Approach &amp; Results: We mapped hepatocellular hnRNPK expression across a broad spectrum of human and murine fibrotic etiologies. Mechanistic insights were obtained by integrating snRNA-seq, hepatocyte-specific alternative splicing profiling, untargeted and spatial metabolomics, and 3D mitochondrial reconstruction using AT-SEM. We identified reduced hepatocellular hnRNPK abundance as a conserved hallmark of liver fibrosis across distinct pathogenic insults, including MASH, ALD, HBV, and DILI.
