STEMI-OP in-hospital mortality prediction algorithms: Frailty-integrated machine learning in older patients undergoing primary PCI.

Despite advances in medical care, older patients with ST-elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI) currently face high in-hospital mortality rates. Traditional prognostic models, primarily developed in Caucasian populations with fewer older participants and using classical statistical approaches, may not perform well in Southeast Asian settings. This study explores the need for artificial intelligence-based risk assessment models-the STEMI-OP algorithms-designed explicitly for STEMI patients aged 60 and older following primary PCI in Vietnam.

Fabrication of 3-Dimensional-Printed Bilayered Scaffold Carboxymethyl Chitosan/Oxidized Xanthan Gum, Biphasic Calcium Phosphate for Osteochondral Regeneration.

Cartilage tissue regeneration remains challenging due to the tissue's poor self-healing capacity, attributed to its hypocellular and avascular nature, which limits nutrient delivery to the defect site and complicates healing. Traditional methods often utilize the subchondral tissue layer to improve nutrient exchange through its vascular network, although these approaches have limitations. To address these issues, 3-dimensional (3D) printing has been employed to create the bilayered scaffold that mimics the complex structure of osteochondral tissue.
