This quasi-experimental study investigated the effect of an antibiotic cycling policy based on time-series analysis of epidemiologic data, which identified antimicrobial drugs and time periods for restriction. Cyclical restrictions of amoxicillin/clavulanic acid, piperacillin/tazobactam, and clarithromycin were undertaken over a 2-year period in the intervention hospital. We used segmented regression analysis to compare the effect on the incidence of healthcare-associated Clostridioides difficile infection (HA-CDI), healthcare-associated methicillin-resistant Staphylococcus aureus (HA-MRSA), and new extended-spectrum β-lactamase (ESBL) isolates and on changes in resistance patterns of the HA-MRSA and ESBL organisms between the intervention and control hospitals. HA-CDI incidence did not change. HA-MRSA incidence increased significantly in the intervention hospital. The resistance of new ESBL isolates to amoxicillin/clavulanic acid and piperacillin/tazobactam decreased significantly in the intervention hospital; however, resistance to piperacillin/tazobactam increased after a return to the standard policy. The results question the value of antibiotic cycling to antibiotic stewardship.

Cefixime (CFX) is a potent antibiotic against gram-positive and gram-negative bacteria that resists degradation and typical removal procedures. This research aimed to synthesize a modified AgCuFeO@GO nanoparticle electrode with anchored MnO for removing CFX by three-dimensional electrochemical oxidation. The physical and chemical characteristics of the nanocomposite were evaluated using various techniques, including FESEM, XRD, EDS-mapping, FTIR, BET, VSM, and TGA.

In this study, we synthesized two nanocomposites, cross-linked PVA/HKUST and PVA/ZIF-67, by integrating metal-organic frameworks (MOFs) into electrospun polyvinyl alcohol (PVA). Several characterization techniques including FTIR, XRD, ICP, SEM, TGA, UV-Vis, zeta potential, and N adsorption-desorption were employed. The adsorption performance of the composites for cefixime (CFX) removal was assessed under varying conditions such as MOF content, contact time, pH, initial CFX concentration, and temperature.

The increasing antibiotic resistance in Pseudomonas aeruginosa, responsible for both community-acquired and hospital-acquired infections, is of global significance. The primary mechanisms contributing to resistance development in P.aeruginosa include the increased activity of efflux pumps, decreased permeability of outer membrane porins and the production of carbapenemases.
