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 Association Between Antibiotic Use and the Incidence of Third-Generation Cephalosporin-Resistance in Escherichia coli Bloodstream Infections: An Ecological Study

Antibiotics
Background/Objectives: The COVID-19 period was marked by changes in antibiotic use and in the incidence of bacterial infections. We examined the association between antibiotic use and the proportion of Escherichia coli bloodstream infections (BSI) that ...

Remote Activation of Wnt Signaling and Cell Proliferation by E‐Cadherin Magnetomechanical Stimulation

Advanced Functional Materials, EarlyView.
A pioneering magnetogenetic toolkit enables non‐invasive, precise spatiotemporal modulation of intracellular Wnt/β‐catenin signaling. Functionalized magnetic nanoparticles (MNPs@E/EC15) target cellular E‐cadherins to generate localized magnetomechanical forces under low‐intensity magnetic fields.

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 ...

Engineering Antigen Density on M13 Bacteriophage for Personalized Nanovaccine

Advanced Healthcare Materials, EarlyView.
Increasing antigen density on the phage capsid impacts phage uptake and antigen cross‐presentation by antigen‐presenting cells, leading to enhanced activation of antitumor CD8+ T cells in the draining lymph nodes. These activated CD8+ T cells subsequently recognize the antigen‐expressing tumors and mediate their specific cytotoxic killing, thereby ...

A Critical Call for Mechanistic Investigations of Metal‐Bacteria Interactions

Advanced Materials, EarlyView.
It is well established that the antibacterial properties of metals have tremendous importance for bioengineering applications. What is not as appreciated, however, is the reproducibility crisis in this field's vast literature. In this perspective, we highlight this reproducibility problem, discuss its sources, and suggest solutions towards focused ...

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

GaSex Nanoparticles Modulate Neutrophil Function and Mitigate NET‐Driven Osteogenic Impairment in Osteomyelitis Therapy

Advanced Materials, EarlyView.
Neutrophil extracellular traps (NETs) emerge as a critical repair‐limiting factor in osteomyelitis, driving osteoblast mitochondrial dysfunction and excessive PINK1/Parkin‐mediated mitophagy. Gallium–selenium nanoparticles (GaSex) scavenge reactive oxygen species, redirect neutrophils from NETosis toward bactericidal phagocytosis, eliminate methicillin‐
