CD70 CAR T cells secreting an anti-CD33/anti-CD3 dual targeting antibody overcome antigen heterogeneity in AML.

CD70 has emerged as a promising target in acute myeloid leukemia (AML), and we have previously demonstrated the potency of an optimized CD70-targeted ligand-based CAR. However, here, we identify in vivo CD70 antigen escape as a limitation of single antigen targeting. Combination targeting of CD70 and CD33 may overcome AML antigen heterogeneity.

Transcription factor TCF1 binds to RORγt and orchestrates a regulatory network that determines homeostatic Th17 cell state.

T helper (Th) 17 cells encompass a spectrum of cell states, including cells that maintain homeostatic tissue functions and pro-inflammatory cells that can drive autoimmune tissue damage. Identifying regulators that determine Th17 cell states can identify ways to control tissue inflammation and restore homeostasis. Here, we found that interleukin (IL)-23, a cytokine critical for inducing pro-inflammatory Th17 cells, decreased transcription factor T cell factor 1 (TCF1) expression.

Update to the Neonatal Early-Onset Sepsis Calculator Utilizing a Contemporary Cohort.

Background And Objectives: The Kaiser Permanente Neonatal Early-Onset Sepsis (EOS) Calculator has been an effective tool for risk stratification to safely reduce newborn antibiotic exposure. The calculator was derived from data on infants born between 1993 and 2007. Since that time, US obstetric practice has adopted universal antepartum screening for group B Streptococcus and intrapartum antibiotic prophylaxis guidance has changed.

Burnout is not associated with trainee performance on the Vascular Surgery In-Training Exam.

Objective: The Vascular Surgery In-Training Examination (VSITE) is a yearly exam evaluating vascular trainees' knowledge base. Although multiple studies have evaluated variables associated with exam outcomes, few have incorporated training program-specific metrics. The purpose of this study is to evaluate the impact of the learning environment and burnout on VSITE performance.
