Skin trauma is a global public health issue, and chronic wound healing is complex. Its care faces problems such as long cycles and poor outcomes. In recent years, research on novel wound dressings and nursing methods has gradually increased, but there is still a lack of systematic summary of nanomaterials dressings for repairing chronic skin wounds. This article reviews the application and nursing effects of nanomaterials dressings in chronic wound repair, explores their potential, and looks forward to the research directions of chronic wound prevention, science popularization, and service system construction, providing a reference for the clinical application of nanomaterials.
During the coronavirus disease 2019 (COVID-19) epidemics, universities take responsibility for the health of their students and epidemic control. Our urgent recommendation focuses on four key questions of emergency management in universities following rigorous evidence-based approaches and provides timely suggestions to university managers, academic faculties and student affairs managers. We recommend universities during the COVID-19 epidemics should: 1) suspend offline lectures; 2) provide proper health education on the disease; 3) encourage face masks, however oppose using N95 masks on the campus; 4) encourage hand hygiene and provide sanitizing products on the campus.
