Pseudomonas aeruginosa (P. aeruginosa) is a common pathogen in hospital-acquired infection and readily able to form biofilms. Due its high antibiotic resistance, traditional antibacterial treatments exert limited effect on P. biofilm infections. It has been indicated that hyperoside inhibits PAO1 (PAO1) formation without affecting growth. Therefore, the current study examined quorum sensing (QS) system of presence hyperoside. Confocal laser scanning microscopy analysis demonstrated...

Abstract Background Teicoplanin has been widely used in patients with infections caused by Staphylococcus aureus, especially for critically ill patients. The pharmacokinetics (PK) of teicoplanin vary between individuals and within the same individual. We aim to establish a prediction model via combination machine learning population PK (PPK) support personalized medication decisions Methods A retrospective study was performed incorporating 33 variables, including PPK parameters (clearance...

Background Voriconazole (VCZ) is a first-line treatment drug for invasive fungal disease, with narrow therapeutic window and significant inter-individual variability. VCZ primarily metabolized by liver, which declines age. For elderly patients, physiological pathological factors lead to more pronounced fluctuations in plasma concentrations. Thus, it crucial establish model that accurately predicts concentration patients. Methods A retrospective study was performed incorporating 32 variables,...
