Dexamethasone Delivery via Amphiphilic, Low‐swelling Hydrogels Treats Postoperative Inflammation in Cervical Spine Applications

Advanced Healthcare Materials, Volume 14, Issue 7, March 14, 2025.
DexaPatch, an implantable, low‐swelling amphiphilic hydrogel system containing dexamethasone‐PLGA microparticles, is developed and characterized for sustained local steroid release to reduce postoperative inflammation in tight surgical spaces. DexaPatch significantly reduces postoperative edema and fibrosis in a rabbit model of anterior spinal surgery,

Biomimetic Glycosaminoglycan‐Analog Hydrogel for Improved Embolization of Aneurysms: Environment‐Selective Swelling

Advanced Healthcare Materials, EarlyView.
Biomimetic glycosaminoglycan analog hydrogels exhibit suitable and robust mechanical properties, as well as hemocompatibility and biocompatibility, making them ideal for the embolization of intracranial aneurysms. Notably, the hydrogel's environment‐selective swelling properties enable complete blockage of the aneurysm cavity while preventing ...

Pyrophosphate‐Containing Calcium Phosphates Negatively Impact Heterotopic Bone Quality

Advanced Healthcare Materials, EarlyView.
The role of calcium pyrophosphate (Ca‐PP) in heterotopic bone formation and material degradation is investigated using calcium phosphate (CaP) compositions with varying Ca‐PP content. Results show that Ca‐PP does not impede heterotopic bone formation, minimally affects CaP degradation at non‐osseous sites, and increases phagocytosis.
