Article Abstract

Frequent and continuous determination of battery internal resistance by a simple current-interrupt method enables the visualisation of cell behaviour through the creation of resistance "maps", showing changes in resistance as a function of both capacity and cycle number. This new approach is applied here for the investigation of cell failure in the lithium-sulfur system with Li electrode excesses optimised towards practically relevant specifications.

Introduction: Tinea pedis is a common disease that affects up to 70% of adults during a lifetime. Most cases are caused by Trichophyton species. Worldwide, terbinafine resistance among dermatophytes is rising, which is concerning as terbinafine is the first-line treatment.

Objectives: To develop a novel risk score (RS) model to predict the probability of progression to castration-resistant prostate cancer (PCa) (CRPC) after intensity-modulated radiation therapy (IMRT) for patients with high- and very high-risk PCa according to the National Comprehensive Cancer Network (NCCN) risk classification, since accurate prediction of the clinical outcome of definitive radiation therapy for patients with high- and very high-risk PCa remains challenging due to its heterogeneity.

Materials And Methods: We conducted a retrospective review of 600 patients with high- and very high-risk PCa treated with IMRT at our institution. They were randomly divided into discovery (n = 300) and validation (n = 300) cohorts.

Background: Chimeric antigen receptor T-cell (CAR-T) therapy has transformed the treatment landscape for relapsed or refractory non-Hodgkin lymphoma, achieving a 5-year overall survival rate of 40-50%. However, relapse remains a major challenge, especially due to CD19-negative clones. Epcoritamab, a bispecific antibody targeting CD20 and CD3, offers a potential solution for post-CAR-T relapse; however, clinical data in this setting remain limited, particularly in Japan.

Antimicrobial resistance is an urgent public health threat, and despite significant consumption of antimicrobials in pregnancy, there remain opportunities for improvement of their use in the obstetric population. Improvement in antimicrobial utilization can be streamlined by assessing baseline characteristics, utilization of diagnostic testing, awareness of peripartum protocols, and recognition of penicillin allergies. In a single healthcare system including 8 obstetric hospitals, an administrative review identified 199 different regimens used among 8,528 patients based on American College of Obstetrician and Gynecologists (ACOG) guidelines.

Background: Ulcerative colitis (UC) is a gastrointestinal inflammatory condition with an unclear etiology. Recent findings suggest that metabolites play a pivotal role in promoting intestinal health. We have previously observed a significant enrichment in colonic branched-chain amino acids (BCAAs) in resistant mice to colitis suggesting the potential role of these metabolites in UC development.
