PHILADELPHIA, October 8, 2021 (Newswire.com) - Dr. Karan Goswami of the Rothman Orthopaedic Institute at Thomas Jefferson University has received the prestigious Eastern Orthopaedic Association's Parvizi Musculoskeletal Infection Award for his paper entitled "Fracture-associated Microbiome and Persistent Nonunion: Next-Generation Sequencing Reveals." This award is given to a Resident or Fellow with one of the top papers presented at the EOA's Annual Meeting.
"Infected nonunion is a major problem," says Dr. Javad Parvizi, Orthopaedic Surgeon and Director of Clinical Research at the Rothman Institute. "Patients suffer long periods of disability and loss of function, and even stand to lose a limb. It also imparts an immense economic burden on the society. Dr. Goswami and colleagues should be congratulated for investigating this important issue. Their findings are sobering and lend support to the role of the microbiome contributing to these infections."
Dr. Goswami's paper, a prospective multicenter study, estimated the microbial contribution to fracture nonunion using next-generation DNA sequencing (NGS) techniques including 16S rRNA gene profiling. Results indicated that NGS detection of pathogens was significantly correlated with persistent nonunion (X2=6.1; p=0.048). NGS was positive in 77% more cases of non-union than traditional culture. Differences in microbial composition between patient outcome groups were also assessed. The study found that increased bacterial diversity was associated with compromised patient outcomes (R2=0.17; p<0.001).
"The fracture-associated microbiome detected using NGS appears to be a significant risk factor for persistent nonunion," says Dr. Goswami. "20 microbial species were especially predictive of poorer outcome within our interim analysis."
The research was funded by MicroGen Diagnostics and NGS testing was performed by MicroGen Diagnostics.
