In recent years, the application of magnetic nanoparticles as alternative catalysts to conventional Fenton processes has been investigated for the removal of emerging pollutants in wastewater. While this type of catalyst reduces the release of iron hydroxides with the treated effluent, it also presents certain disadvantages, such as slower reaction kinetics associated with the availability of iron and mass transfer limitations. To overcome these drawbacks, the functionalization of the nanocatalyst surface through the addition of coatings such as polyacrylic acid (PAA) and their immobilization on a mesoporous silica matrix (SBA15) can be factors that improve the dispersion and stability of the nanoparticles.

Article Synopsis
- The study investigates healthcare-associated (HCA) bacteremic urinary tract infections (BUTI), comparing community-onset (CO-HCA) and hospital-acquired (HA) cases, particularly focusing on multidrug resistance (MDR) and outcomes.
- Conducted as a multicenter cohort study, it involved adult patients with specific inclusion and exclusion criteria, looking at factors like mortality and treatment appropriateness.
- Results showed a high prevalence of MDR (61.2%) among patients, with CO-HCA-BUTI patients generally older and sicker than those with HA-BUTI; however, mortality rates were not influenced by infection acquisition site or MDR presence.
