Two Central Nervous System Tumors in One Catheter Lab: Time to Rethink Radiation Protection

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Very little research has been done on the possible effects that repeated, frequent, and low‐dose ionizing radiation exposure has on the long‐term health of interventional cardiologists. Aims Following the diagnosis in the same year of two central nervous system tumors in two operators working in the same catheter laboratory, we ...

Unveiling the health‐promoting potential of Sudanese sorghum landraces: A legacy rooted in Eastern Sudan, Kassala, and the Red Sea States

PLANTS, PEOPLE, PLANET, EarlyView.
Sorghum is a staple food for hundreds of millions of people in dry regions worldwide, and improving its nutritional quality is vital for global food and health security under climate change. In this study, we evaluated traditional Sudanese sorghum varieties grown in eastern deltas to better understand their natural health‐promoting properties. We found

Patient Dose Optimisation of Abdominopelvic Protocols During X‐Ray Imaging

Journal of Medical Radiation Sciences, Volume 73, Issue 2, Page 156-163, June 2026.
This study evaluates organ doses in abdominopelvic radiography for both erect and supine positions, addressing dose optimisation concerns in Ghana. Using CalDose X and thermoluminescence dosimeters, organ doses and image quality were analysed, revealing significant dose reductions with optimised exposure parameters (70 kVp, 10 mAs, 110 cm FDD).
