Researchers at the Icahn School of Medicine at Mount Sinai and their collaborators have developed a new technology to track beneficial bacteria after fecal microbiota transplants (FMT). The approach provides a detailed view of how donor microbes take hold and persist in the patients’ gut—not only which bacteria successfully colonized but how they change over time. These insights may guide the design of safer and more effective microbiome-based therapies. The study was published in the October 22 online issue of Nature Microbiology [DOI: https://doi.org/10.1038/s41564-025-02164-8].
A new paper in Rheumatology finds that retired UK male professional football players who reported foot or ankle injuries during their careers were more likely to develop osteoarthritis in retirement. Retired players treated routinely with cortisone injections for their injuries were even more likely to report osteoarthritis.
