Dynamically Actuated Reconfigurable Topographical Surface Enables Active Control of Implant‐Associated Infections

Advanced Functional Materials, EarlyView.
A dynamically actuated reconfigurable topographical surface (DARTS) integrates contact‐mediated bactericidal nanotopography with programmable mechanical actuation to actively disrupt bacterial biofilms. Dynamic surface reconfiguration enhances bacterial killing and suppresses implant‐associated infections in vivo, providing a new strategy for active ...

The Yield of One vs. Two Blood Cultures in Children: Under-Detection and Over-Testing

Antibiotics
We aimed to determine whether obtaining two blood cultures (BCs) instead of one improved the detection of bloodstream infections (BSIs) in children. For this descriptive study, we used surveillance data collected in 2019–2021 from all Israeli hospitals ...

Consumption of antibiotics at St Luke’s Hospital : a critical factor behind the local prevalence of antimicrobial resistance? [PDF]

, 2006
The intensity of antibiotic use in hospital settings is recognised as possibly the most important factor for the selection of antimicrobial resistance. Hospitals are therefore being encouraged to undertake surveillance and benchmarking of antimicrobial ...

Virulence factors are preserved within carbapenem-resistant Acinetobacter baumannii clades

Virulence
Carbapenem-resistant Acinetobacter baumannii (CRAB) is an important threat to hospitalized patients. The virulence of A. baumannii varies between strains and geographic locations, which is believed to be related to its genetic plasticity. A comprehensive

Charting Morphotoxicity With Complementary Embryo Models

Advanced Healthcare Materials, EarlyView.
Three human embryo models of the peri‐implantation stages are exposed to a library of compounds. The (toxic) effects of the compounds are analyzed through automated image analysis pipelines. By evaluating the differential responses of the embryo models, this study underscores the importance of testing complementary embryo models to achieve robust and ...

Alternate Strategies for Managing Resistance to Antibiotics and Pesticides [PDF]

How should one manage the problem of resistance to antibiotics and pesticides? Although the salience of this question has now been recognized, the formal modeling of this question is very much in its infancy.

Hydrogels Augmented With Artificial Sweeteners can Inhibit Multidrug‐Resistant Acinetobacter baumannii Growth and Biofilm Formation While Demonstrating Safety in Pre‐Clinical Pilot Human Trials

Advanced Healthcare Materials, EarlyView.
Using PVA–borax hydrogels as carriers for off‐the‐shelf artificial sweeteners to fight multidrug‐resistant A. baumannii. These soft, biocompatible hydrogels rapidly reduce bacterial viability within multidrug‐resistant A. baumannii biofilms by more than 99% within one hour and sustain antimicrobial activity over time, while demonstrating safety in both

Conjugated Porphyrin Polymer With Superior Charge Transfer for Photodynamic‐Immunomodulatory Prevention of CIED Infection in Diabetes

Advanced Healthcare Materials, EarlyView.
Under NIR irradiation, PTCPP generates ROS to eliminate MRSA biofilms and promote M1 macrophage polarization for phagocytosis. After bacterial clearance, the material is phagocytosed by macrophages, shifting their polarization to M2 phenotype via metabolic reprogramming, which synergistically enhances anti‐infection therapy and wound healing.
