Boruta Algorithm–Guided Antibiotic Selection in Antibiotic-Loaded Bone Cement for Diabetic Foot Ulcers: Microbiota and Susceptibility Analysis
Summary: A new study explores how machine learning can improve antibiotic choices in treating diabetic foot ulcer infections (DFIs) with antibiotic-loaded bone cement. By analyzing wound microbiota and using the Boruta algorithm, researchers identified antibiotics most effective against common pathogens and highlighted the role of patient age in guiding therapy.
Key Highlights:
- Study approach: Exudates from DFI wounds were cultured for bacterial identification and antibiotic susceptibility testing. The Boruta algorithm was applied to evaluate antibiotic effectiveness.
- Microbiota profile: Gram-positive organisms dominated, with Staphylococcus aureus frequently isolated.
- Antibiotic options: Gentamicin and tobramycin emerged as effective for gram-negative bacteria, while moxifloxacin, ampicillin, and quinupristin-dalfopristin showed strong performance against gram-positive isolates.
- Influence of age: Patient age significantly affected cumulative bacterial sensitivity, suggesting the need for age-aware antibiotic protocols.
- Clinical implications: Tailoring antibiotic selection to both pathogen profiles and patient demographics may improve DFI outcomes and reduce resistance risks.
