Endonucleases have recently widely used in molecular diagnostics. Here, we report a strategy to exploit the properties of Argonaute (Ago) proteins for molecular diagnostics by introducing an artificial nucleic acid circuit with Ago protein (ANCA) method. The ANCA is designed to perform a continuous autocatalytic reaction through cross-catalytic cleavage of the Ago protein, enabling one-step, amplification-free, and isothermal DNA detection. Using the ANCA method, carbapenemase-producing Klebsiella pneumoniae (CPKP) are successfully detected without DNA extraction and amplification steps. In addition, we demonstrate the detection of carbapenem-resistant bacteria in human urine and blood samples using the method. We also demonstrate the direct identification of CPKP swabbed from surfaces using the ANCA method in conjunction with a three-dimensional nanopillar structure. Finally, the ANCA method is applied to detect CPKP in rectal swab specimens from infected patients, achieving sensitivity and specificity of 100% and 100%, respectively. The developed method can contribute to simple, rapid and accurate diagnosis of CPKP, which can help prevent nosocomial infections.

Background And Objectives: Deucravacitinib, a first-in-class, oral, selective, allosteric tyrosine kinase 2 inhibitor, demonstrated efficacy across the primary endpoint and all key secondary endpoints in the phase 2 PAISLEY SLE trial in patients with active systemic lupus erythematosus (SLE). Here, we describe 2 phase 3 trials [POETYK SLE-1 (NCT05617677), POETYK SLE-2 (NCT05620407)] which will assess the efficacy and safety of deucravacitinib in patients with active SLE. These phase 3 trials have been designed to replicate the successful elements of the phase 2 trial, including its glucocorticoid-tapering strategy and disease activity adjudication.

Introduction: Anti-neutrophil cytoplasmic antibodies (ANCAs) have been reported in systemic lupus erythematosus (SLE). Their clinical significance remains unclear especially in the African populations. This study aimed to assess the prevalence, antigenic targets, and clinical correlations of ANCAs in SLE patients in a Tunisian (North African) cohort.

Objectives: This retrospective cohort study aimed to evaluate real-world data on the efficacy of rituximab (RTX) alone versus combined rituximab/cyclophosphamide (RTX/CYC) induction therapy, followed by RTX maintenance, compared with cyclophosphamide-azathioprine (CYC-AZA) therapy in ANCA-associated vasculitis (AAV).
Methods: Patients with new-onset or relapsing organ- or life-threatening AAV (granulomatosis with polyangiitis [GPA] n=97; microscopic polyangiitis [MPA], n=69) were followed over 24-months. Patients with previous RTX and/or CYC therapy were excluded.

Objective: To evaluate standardized incidence ratios (SIRs) of cancer in patients with antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV).
Methods: A systematic review and meta-analysis of studies from Medline, Embase, and Cochrane databases (inception to May 2025) was performed. Pooled SIRs were analyzed overall and by region, sex, age, AAV subtype, and cancer type.

Purpose: Acute bowel obstruction (ABO) is a common indication for emergency abdominal surgery, often performed on a severely dilated intestine with compromised barrier function. The recovery of bowel motility in this acute setting differs from elective surgery and remains insufficiently investigated. Yet, its understanding is crucial for improving perioperative care in surgical emergencies.
