Periprosthetic joint infection (PJI) is a devastating complication of joint replacement surgery. A new study in the Journal of Sport and Health Science discovers that musclin, a hormone released by muscles during exercise, directly binds to macrophages. This interaction rewires cellular metabolism, significantly boosting the macrophages' ability to clear dead cells (efferocytosis). This process effectively resolves inflammation, reduces bacterial burden, and promotes tissue repair, offering a promising "exercise-mimetic" therapeutic strategy for managing implant-associated infections.

A research team in Japan has developed an efficient and minimally invasive cancer detection device that uses high-performance zinc oxide nanowires to selectively capture extracellular vesicles (EVs) from bodily fluids. Using this device, researchers successfully captured cancer-related EVs from the blood serum of ovarian cancer patients.

A novel study among Indigenous communities in Canada utilizing sharing circles as the primary method of qualitative data collection shows that heart health is shaped by emotional, spiritual, social, and systemic factors, with trauma strongly influencing how care is accessed and trusted. Results of the study appear in CJC Open, published by Elsevier, as the journal’s first arts-based report. This novel format provides an authentic visual narrative that reflects the depth of community experiences and perspectives.
