Children with Staphylococcus aureus bacteremia (SAB) generally presented with nonsevere signs and symptoms in sharp contrast to reports of adults with SAB. Despite incomplete adherence to current management guidelines, children with SAB did not experience mortality or relapse. Molecular characteristics of strains responsible for SAB in children were not significantly different than those described in adults. Improved outcomes in pediatric SAB compared with adults may most likely be attributed to less severe comorbidities in children.

The healing of bacterial biofilm-infected wounds is a complex process, and the construction of emerging therapeutic modalities that regulate the microenvironment to magnify therapeutic effects and reduce biotoxicity is still highly challenging. Herein, an engineered microneedle (MN) patch is reported to mediate the efficient delivery of black phosphorus nanosheets (BP NSs) and copper peroxide nanodots (CP NDs) for dual nanodynamic sterilization and methicillin-resistant staphylococcus aureus (MRSA)-infected wound healing. Results demonstrate that the system can eliminate biofilm, reduce cytotoxicity, promote angiogenesis and tissue regeneration by the multiple advantages of chemodynamic therapy (CDT), enhanced photodynamic therapy (PDT), and improved degradation process from BP NSs to phosphate for promoting cell proliferation.

In dental implant surgery, infection is identified as the primary factor contributing to the failure of bone grafts. There is an urgent need to develop bone graft materials possessing antibacterial characteristics to facilitate bone regeneration. Magnesium phosphate bone cement (MPC) is highly desirable for bone regeneration due to its favorable biocompatibility, plasticity, and osteogenic capabilities.

Ceftobiprole was recently approved by the United States (US) Food and Drug Administration (FDA) for the treatment of adult patients with bacteremia, including right-side endocarditis, acute bacterial skin and skin structure infections, and community-acquired bacterial pneumonia in adults and pediatrics. Ceftobiprole is an advanced-generation cephalosporin approved in many countries for the treatment of adults with community-acquired pneumonia and hospital-acquired pneumonia, excluding ventilator-associated pneumonia. We evaluated the activities of ceftobiprole and comparators against methicillin-resistant (MRSA) and multidrug-resistant (MDR) clinical isolates.

The presented research introduces a new method to identify drug-resistant bacteria rapidly with high accuracy using artificial intelligence combined with Multi-angle Dynamic Light Scattering (MDLS) signals and Raman scattering signals. The main research focus is to distinguish methicillin-resistant (MRSA) and methicillin-sensitive (MSSA). First, a microfluidic platform was developed embedded with optical fibers to acquire the MDLS signals of bacteria and Raman scattering signals obtained by using a Raman spectrometer.
