Article Abstract

Background: Histotripsy is a novel, non-invasive, non-ionizing, and non-thermal ablation technique that disrupts tumors using acoustic cavitation. We report the first use of Histotripsy as bridging therapy prior to liver transplant for hepatocellular carcinoma (HCC) treated with histotripsy.

Case Presentation: A 59-year-old woman presented with Metabolic-Associated Steatotic Liver Disease (MASLD) cirrhosis (labMELD = 14), hepatic encephalopathy, and a single 2 cm OPTN V lesion in the left lateral segment consistent with HCC. The patient underwent histotripsy treatment of the lesion as bridging therapy before receiving liver transplantation. Histopathology analysis of the explanted liver showed total necrosis of the treated area, with no residual viable tissue tumor.

Conclusion: This case demonstrates the potential utility of histotripsy as an effective bridging therapy for patients with combined cirrhosis and hepatocellular carcinoma (HCC) awaiting liver transplantation, with complete tumor necrosis on explant pathology demonstrating its therapeutic efficacy.

Post-recurrence Survival After Liver Transplantation for Hepatocellular Carcinoma.

Transplantation

September 2025

General Surgery and Liver Transplantation Unit, Fondazione IRCCS Istituto Nazionale Tumori, Milan, Italy.

Background: Mortality after liver transplantation (LT) for hepatocellular carcinoma (HCC) is mainly driven by HCC recurrence. We sought to determine whether post-recurrence survival (PRS) has improved during the last 2 decades.

Methods: Using the Scientific Registry of Transplant Recipients, we included all patients who underwent LT for HCC between 2003 and 2020 and experienced HCC recurrence.

Discovery of Potential GPRC5D Inhibitors through Virtual Screening and Molecular Dynamics Simulations.

ChemistryOpen

September 2025

Bone Marrow Transplantation Center, the First Affiliated Hospital, Zhejiang University School of Medicine, Hangzhou, Zhejiang, 310003, China.

G protein-coupled receptor family C, group 5, member D (GPRC5D), a member of the G protein-coupled receptor (GPCR) family, has recently emerged as a promising target for immunotherapy in hematologic malignancies, particularly multiple myeloma. However, no systematic virtual screening studies have been conducted to identify small-molecule inhibitors targeting GPRC5D. To address this gap, a multistep computational screening strategy is developed that integrates Protein-Ligand Affinity prediction NETwork (PLANET), a GPU-accelerated version of AutoDock Vina (Vina-GPU), molecular mechanics/generalized born surface area (MM/GBSA), and an online tool for Absorption, Distribution, Metabolism, Excretion, and Toxicity (ADMET) property prediction (admetSAR 3.

Home parenteral nutrition (HPN) is a life-sustaining therapy traditionally used as a bridge to enteral autonomy or intestinal transplantation. Increasingly, it is used for intractable feeding intolerance (IFI), which can occur near the end of life (EOL) in children with severe neurological impairment (SNI). In these cases, HPN use differs from its historical role and requires tailored outpatient planning.

Secondary mitral regurgitation (SMR) remains a prevalent and challenging complication in patients with heart failure (HF), associated with poor prognosis despite optimal guideline-directed medical therapy (GDMT) and cardiac resynchronization therapy. Current American and European guidelines recommend GDMT as first-line therapy, with transcatheter edge-to-edge repair (TEER) reserved for severe symptomatic SMR patients who remain refractory. However, both guidelines preceded the reporting of pivotal randomized controlled trials (RESHAPE-HF2, MATTERHORN, and EFFORT) and emerging evidence in new clinical scenarios.

The interaction between the skin microbiome and antimicrobial peptides within the epidermal immune microenvironment: Bridging insights into atopic dermatitis.

Allergol Int

September 2025

Atopy (Allergy) Research Center, Juntendo University Graduate School of Medicine, Tokyo, Japan; Faculty of International Liberal Arts, Juntendo University, Tokyo, Japan. Electronic address:

The epidermal immune microenvironment is a multifaceted system in which the interplay between the skin microbiome and antimicrobial peptides plays a pivotal role in sustaining skin homeostasis and preventing dysbiosis. Disruption of these interactions can lead to inflammatory skin conditions such as atopic dermatitis. This review aims to explore the complex mechanisms by which antimicrobial peptides and the skin microbiome communicate within the epidermal immune microenvironment, emphasizing causal dynamics and the dual role of antimicrobial peptides.
