Solution Overview
Problem
Current methods lack effective strategies for diagnosing, preventing, and mitigating biofilms formed by Pseudomonas aeruginosa, which are highly resistant to antibiotics and contribute to various infections.
Innovation Solution
The use of NMR-based metabolomics to identify and detect metabolites in joint fluid, specifically targeting the lysine degradation pathway, to prevent bacterial biofilm accumulation and treat joint infections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional diagnostic methods are used for joint infections, then the diagnosis process is simple, but the detection precision and effectiveness are insufficient
Solution Approach 1:
The patent replaces conventional mechanical/culturing-based diagnostic methods with NMR-based metabolomics. This substitution enables non-invasive, high-precision detection of metabolic markers (such as succinate, acetate, and other metabolites) in joint fluid, allowing early and accurate diagnosis of periprosthetic joint infections without requiring extensive bacterial culturing or complex procedural interventions.
Solution Approach 2:
The patent utilizes changes in metabolic parameters (metabolite concentrations, ratios, and profiles) as diagnostic markers. By monitoring changes in specific metabolites (e.g., succinate/acetate ratio, glutarate levels) in joint fluid, the system transforms physical-chemical parameters into diagnostic information, enabling precise detection of infection states and biofilm formation without complex mechanical procedures.
2Reliability
If antibiotic treatment is applied to treat joint infections, then the treatment effectiveness is limited, but the resistance and recurrence increase
Solution Approach 1:
The patent converts the harmful biofilm structure, which normally provides antibiotic resistance, into a diagnostic target. By detecting specific metabolites (such as succinate, acetate, and glutarate) that are produced during biofilm formation, the system identifies infection states that would otherwise be resistant to conventional antibiotics, enabling targeted interventions that overcome biofilm-related resistance mechanisms.
Solution Approach 2:
The patent monitors changes in metabolic parameters (metabolite concentrations and ratios) to assess treatment response and guide therapeutic adjustments. By tracking dynamic changes in metabolite profiles during treatment, the system can detect emerging resistance patterns and adjust antibiotic regimens or add adjunctive therapies to overcome biofilm formation and persistent infections.
3Object-affected harmful factors
If biofilm formation is allowed to occur, then the bacterial protection is enhanced, but the infection severity and recurrence increase
Solution Approach 1:
The patent enables preliminary detection of biofilm formation through metabolite analysis in joint fluid before the infection fully develops or becomes severe. By identifying metabolic signatures of biofilm formation (such as specific metabolite ratios and profiles), the system allows early intervention to prevent biofilm establishment, thereby avoiding the severe infections and recurrences that would result from allowing biofilm formation to proceed.
Solution Approach 2:
The patent implements feedback mechanisms by continuously monitoring metabolite changes in joint fluid to assess biofilm formation status and treatment effectiveness. This feedback loop allows real-time adjustment of therapeutic strategies to prevent or reverse biofilm formation, preventing the progression to severe infections while adapting to the dynamic nature of biofilm development and host response.
