A humanitarian medical delegation of senior physicians and medical students has begun operating in Kenya as part of the “Humanitarian Elective,” an initiative focused on supporting local healthcare teams while providing participants with immersive clinical experience in resource-limited settings. Through hands-on work in emergency and pediatric medicine, students are learning to navigate medical crises, healthcare inequality, cultural differences, and severe shortages of equipment and infrastructure. Organizers hope the program will help shape a new generation of globally minded physicians and establish humanitarian medicine as a natural part of medical training.

A new machine-learning approach for prostate-specific membrane antigen (PSMA) treatment of metastatic castration-resistant prostate cancer (mCRPC) could estimate radiation dose to tumors and healthy organs before therapy begins. Using data already available from pre-therapy PET/CT scans, this novel prediction tool could help personalize treatment plans, improve patient selection, and reduce toxicity risk. This research was presented at the Society of Nuclear Medicine and Molecular Imaging 2026 Annual Meeting.

In a review published in Immunity & Inflammation, Prof. Chen-Yu Zhang from the State Key Laboratory of Pharmaceutical Biotechnology at Nanjing University has synthesized two decades of progress in extracellular RNA biology. Their article, titled “EV-encapsulated extracellular microRNAs as orchestrators of systemic communication in immunity and inflammation,” traces the remarkable evolution of circulating microRNAs (miRNAs) from stable biomarkers in biofluids to active orchestrators of long-range immune regulation and inter-organ crosstalk. The review positions EV-encapsulated miRNAs as a sophisticated “molecular postal system” and “hidden language” that coordinates systemic communication in metabolism, tissue repair, and immune homeostasis.

Wastewater treatment protects rivers, cities, and public health, but it also carries a hidden climate cost. 

Vasken Dilsizian, MD, FSNMMI, MASNC, FACC, FAHA, professor of radiology and medicine at the University of Maryland School of Medicine in Baltimore, has been honored with two important distinctions at the Society of Nuclear Medicine and Molecular Imaging (SNMMI) 2026 Annual Meeting.
