Background: Health care is shifting toward 5 proactive approaches: personalized, participatory, preventive, predictive, and precision-focused services (P5 medicine). This patient-centered care leverages technologies such as artificial intelligence (AI)-powered robots, which can personalize and enhance services for users with disabilities. These advancements are crucial given the World Health Organization's projection of a global shortage of up to 10 million health care workers by 2030.

Herein we report on an environmentally friendly and scalable production route for hollow silica spheres (HSSs). The process is based on close to 100% conversion of non-crystalline solid Si nanoparticles ( = 40 ± 9 nm) in mild alkaline solutions (pH ≤ 9.0) at ambient temperature.

Article Synopsis
  • * Porous silicon nanoparticles can effectively encapsulate APIs in an amorphous state, enhancing their dissolution rates compared to crystalline forms, and a new synthesis method using centrifugal Chemical Vapor Deposition (cCVD) has been developed to facilitate this process.
  • * Research showed that cCVD Si particles significantly increased dissolution rates for various model drugs, with additional improvements when drug–cyclodextrin complexes were loaded, suggesting effective strategies for enhancing drug bioavailability.

Background: Nursing students' learning during clinical practice is largely influenced by the quality of the guidance they receive from their nurse preceptors. Students that have attended placement in nursing home settings have called for more time with nurse preceptors and an opportunity for more help from the nurses for reflection and developing critical thinking skills. To strengthen students' guidance and assessment and enhance students' learning in the practice setting, it has also been recommended to improve the collaboration between faculties and nurse preceptors.
