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.

Chemotherapy combined with immune checkpoint inhibitors may overcome the detrimental effect of high neutrophil-to-lymphocyte ratio prior to treatment in esophageal cancer patients.

Introduction: Immune checkpoint inhibitors (ICIs) have emerged as a promising treatment option for esophageal cancer (EC). Although ICIs enable long-term survival in some patients, the efficacy of ICIs varies widely among patients. Therefore, predictive biomarkers are necessary for identifying patients who are most likely to benefit from ICIs to improve the efficacy of the treatment.

Rare forms of hypomyelination and delayed myelination.

Hypomyelination is defined by the evidence of an unchanged pattern of deficient myelination on two MRIs performed at least 6 months apart in a child older than 1 year. When the temporal criteria are not fulfilled, and the follow-up MRI shows a progression of the myelination even if still not adequate for age, hypomyelination is excluded and the pattern is instead consistent with delayed myelination. This can be mild and nonspecific in some cases, while in other cases there is a severe delay that in the first disease stages could be difficult to differentiate from hypomyelination.

Regional Collaboration for Heart Failure Patients Certified as Needing Support or Care in Long-Term Care Insurance System.

Background: Heart failure (HF) patients with complex care needs often experience exacerbations during the transitional phase as care providers and settings change. Regional collaboration aims to ensure continuity of care; however, its impact on vulnerable patients certified as needing support or care under the Japanese long-term care insurance (LTCI) system remains unclear.

Methods And Results: We implemented a regional collaborative program for HF patients involving 3 pillars of transitional care with general practitioners and nursing care facilities: (1) standardized health monitoring using a patient diary and identification of exacerbation warning signs; (2) standardized information sharing among care providers; and (3) standardized HF management manuals.
