Bacterial infections of the central nervous system, especially acute infections such as bacterial meningitis require immediate, invariably empiric antibiotic therapy due to the widespread emergence of resistance among bacterial species. Nosocomial infections by Pseudomonas aeruginosa have been described with an increasing trend towards multidrug resistance. P. aeruginosa isolates n = 53 (66%) isolated from the cerebrospinal fluid (CSF) were used for this study. Antibiotic resistance in 53 P. aeruginosa clinical isolates from 80 CSF samples were evaluated. Of these, n = 42 (80%) of the isolates showed multidrug resistance to more than eight antibiotics and n = 17 (32%) isolates were found to be imipenem resistant P. aeruginosa (IMPR-Pa). Genotypical examination by ERIC based PCR revealed minor genetic variations. Polymicrobial infections are common in the CSF samples. However, high prevalence of P. aeruginosa as an opportunistic pathogen has been developing with increased resistance to antimicrobial agents and thus becoming a significant threat.

Objective: Rheumatoid arthritis (RA) is an autoimmune condition that causes severe joint deformities and impaired functionality, affecting the well-being and daily life of individuals. Consequently, there is a pressing demand for identifying viable therapeutic targets for treating RA. This study aimed to explore the molecular mechanisms of osteoclast differentiation in PBMC from patients with RA through transcriptome sequencing and bioinformatics analysis.

Alzheimer's disease (AD) is an irreversible neurodegenerative disorder that poses a significant risk to human health and well-being. The high cost and invasiveness of neuroimaging and cerebrospinal fluid (CSF) analysis underscores the necessity for accessible early screening via blood samples. In this study, we developed an ultrasound-based strategy for emergent macroscopic that enhances the acoustic response enrichment of specific proteins by introducing functionalized microspheres.

Background: Trilaciclib is a transient cyclin-dependent kinase 4/6 (CDK4/6) inhibitor that reduces the incidence of chemotherapy-induced myelosuppression (CIM). In this pooled analysis, we evaluated the multilineage myeloprotection, antitumor efficacy, and safety of trilaciclib treatment in patients with extensive-stage small-cell lung cancer (ES-SCLC). Moreover, myeloprotection effect in 1 L, 2 L/3 L population and effect by risk category were explored.

Objective: Ventricular shunt insertion is a common procedure in pediatric neurosurgical practice. In many areas of medicine there is a push toward rationalization of healthcare resources and a reduction in low-value tests or procedures. The intraoperative sampling of CSF at the time of shunt insertion is one traditional aspect of care that has not been rigorously evaluated.

Introduction: We evaluated the diagnostic performance of two commercial plasma p-tau217 immunoassays compared to cerebrospinal fluid (CSF) testing and neuropathology.
Methods: One hundred and seventy plasma samples from the University of British Columbia Hospital Clinic for Alzheimer's (AD) and Related Disorders were analyzed for p-tau217 using Fujirebio and ALZpath assays. Decision points were determined using CSF testing and autopsy findings as the standard.
