Multimodal integration of blood RNA and ctDNA reflects response to immunotherapy in metastatic urothelial cancer.
JCI Insight
January 2025
Medical Oncology Department, Research Institute for Medical Innovation, Radboud University Medical Center, Nijmegen, Netherlands.
Background: Previously, we demonstrated that changes in circulating tumor DNA (ctDNA) are promising biomarkers for early response prediction (ERP) to immune checkpoint inhibitors (ICI) in metastatic urothelial cancer (mUC). In this study, we investigated the value of whole blood immunotranscriptomics for ERP-ICI and integrated both biomarkers into a multimodal model to boost accuracy.
Methods: Blood samples of 93 patients were collected at baseline and after 2-6 weeks of ICI for ctDNA (N=88) and immunotranscriptome (N=79) analyses.
Urinary DNA Methylation Test for Bladder Cancer Diagnosis.
JAMA Oncol
January 2025
Department of Urology, Seoul National University Hospital, Seoul, Republic of Korea.
Importance: An accurate noninvasive biomarker test is needed for the early diagnosis of bladder cancer.
Objective: To evaluate the performance of a urinary DNA methylation test (PENK methylation) and compare its diagnostic accuracy with that of the nuclear matrix protein 22 (NMP22) test or urine cytology test.
Design, Setting, And Participants: In this prospective multicenter study at 10 sites in the Republic of Korea, individuals 40 years and older with hematuria undergoing cystoscopy within 3 months between March 11, 2022, and May 30, 2024, participated.
Targeted inhibition of PqsR in Pseudomonas aeruginosa PAO1 quorum-sensing network by chalcones as promising antibacterial compounds.
Mol Biol Rep
January 2025
Department of Pharmaceutical Control, School of Pharmacy, Mashhad University of Medical Sciences, Mashhad, Iran.
Background: Pseudomonas aeruginosa's inherent and adapted resistance makes this pathogen a serious problem for antimicrobial treatments. Furthermore, its biofilm formation ability is the most critical armor against antimicrobial therapy, and the virulence factors, on the other hand, contribute to fatal infection and other recalcitrant phenotypic characteristics. These capabilities are harmonized through cell-cell communication called Quorum Sensing (QS), which results in gene expression regulation via three major interconnected circuits: las, rhl, and pqs system.

J Endocrinol Invest
January 2025
Department of Medical Area, Section of Metabolic Diseases and Diabetes, University Hospital of Pisa, Via Paradisa, 2, Pisa, 56124, Italy.
Purpose: Women with gestational diabetes (GDM) have increased risk of hypertensive disorders in pregnancy (HDP). However, knowledge remains limited for women with high-risk metabolic profiles, regardless of GDM diagnosis. This study aimed to evaluate the prevalence of HDP among women at high risk for GDM, while simultaneously identifying potential predictive clinical risk factors of HDP.

Epstein-Barr virus (EBV)-related hemophagocytic lymphohistiocytosis (EBV-HLH) and infectious mononucleosis (IM) are characterized by fever, hepatomegaly, and splenomegaly, but HLH has a 50% lethality rate. Therefore, this study aimed to compare the laboratory findings in differentiating EBV-HLH children from IM children who have fever, hepatomegaly, or splenomegaly. A total of 131 IM patients and 29 EBV-HLH pediatric patients with fever, hepatomegaly, or splenomegaly were enrolled in our study.
