Revolutionary 3D treatment for diabetes
Researchers at Queen's University Belfast have designed a new bandage treatment, known as a scaffold, to treat diabetic foot ulcers, which is cost-effective while improving patient outcomes.
Produced by 3D bioprinting, the scaffolds slowly release antibiotics over a four-week period to effectively treat the wound.
Diabetes, a lifelong condition that causes a person's blood sugar level to become too high, is among the top ten causes of deaths worldwide.
Diabetic foot ulcer (DFU), is a serious complication of diabetes, affecting approximately 25% of diabetic patients. When identified, over 50% are already infected and over 70% of cases result in lower limb amputation.

Cavity-causing microbes can form crawling superorganisms
A cross-kingdom partnership between bacteria and fungi can result in the two joining to form a "superorganism" with unusual strength and resilience. Found in the saliva of toddlers with severe childhood tooth decay, these assemblages can effectively colonize teeth. They were stickier, more resistant to antimicrobials, and more difficult to remove from teeth than either the bacteria or the fungi alone, according to the research team, led by University of Pennsylvania School of Dental Medicine scientists.
