Immune Stress-induced Tumor Mutation Burden and Neoantigen Expression in 4T1 Mammary Cancer Cells: A Potential Mechanism for Long-term Survival in Patients Treated With Immune Checkpoint Inhibitors.

Background/aim: The Kaplan-Meier curves for patients treated with immune checkpoint inhibitors (ICIs) display a small group of potentially-cured patients with long-term survival, creating a 'kangaroo-tail' shape of the survival curve. However, the mechanistic basis of this phenomenon and what occurs in patients whose cancer is resistant to ICIs remain unclear. The present study aimed to answer these questions.

Current Approaches to Optimize Donor Heart for Transplantation.

Heart transplantation remains a critical therapy for patients with end-stage heart failure, offering incremental survival and improved quality of life. One of the key components behind the success of heart transplantation is the condition and preservation of the donor heart. In this review, we provide a comprehensive overview of ischemic reperfusion injury, risk factors associated with primary graft dysfunction, current use of various preservation solutions for organ procurement and recent advancements in donor heart procurement technologies.

Utilization and regional disparities of radiotherapy in cancer treatment in Japan: a longitudinal study using NDB open data.

The National Database of Health Insurance Claims and Specific Health Checkups of Japan (NDB) is a database that stores anonymized information on medical receipts and health checkups in Japan. The NDB Open Data is a publicly accessible summary table of the NDB database. To reveal annual trends and regional disparities in radiotherapy utilization in Japan, we analyzed the NDB Open Data tables for a 9-year period from 2014 to 2022.

Unfractionated heparin monitoring by anti-factor Xa versus activated partial thromboplastin time strategies during venoarterial extracorporeal life support.

Introduction: No clear guidelines exist for unfractionated heparin (UFH) monitoring in adult patients on veno-arterial extracorporeal life support (VA-ECLS) for refractory cardiogenic shock. In this study, we sought to compare outcomes between anti-factor Xa (FXa) and activated partial thromboplastin time (aPTT) strategies for UFH monitoring during VA-ECLS.

Methods: This is a single-center, retrospective review of VA-ECLS patients who received UFH in the cardiothoracic intensive care unit between July 2019 and November 2023.

Antifungal Treatment for Japanese Patients with Chronic Pulmonary Aspergillosis.

Introduction: Despite the ongoing efforts to refine treatment durations and methods for patients with chronic pulmonary aspergillosis, the clinical use of antifungal agents remains unclear. This study aimed to describe the treatment practices, trajectories, and prognoses of newly diagnosed patients with chronic pulmonary aspergillosis.

Methods: Data from a longitudinal database from hospitals in Japan was used.
