Antimicrobial stewardship: knowledge, attitudes and practices regarding antimicrobial use and resistance among non-healthcare students at the University of Zambia.

Background: Antimicrobial resistance (AMR) poses a significant threat to the world and could become humanity's next major challenge. This study assessed non-healthcare students' knowledge, attitude and practices (KAP) towards antimicrobial use (AMU) and AMR at the University of Zambia. Methods: This cross-sectional study was conducted among 443 non-healthcare students from August to October 2022 using a structured questionnaire. Data analysis was done using IBM SPSS version 24.0. Results: Of the 433 participants, 55.2%, 63.5% and 45% had moderate KAP scores regarding AMU and AMR. The prevalence of self-medication with antibiotics was 76.7%. Male participants were less likely to have good knowledge (OR = 0.524, 95% CI: 0.347-0.792) and positive attitudes (OR = 0.585, 95% CI: 0.364-0.940) towards AMU and AMR compared with females. Students who were studying Engineering and Mining were more likely to have good knowledge of AMR (OR = 1.891, 95% CI: 1.197-2.987) compared with those in Social Sciences. Those who were in their fourth and fifth years were more likely to have positive attitudes towards AMU and AMR (OR = 1.851, 95% CI: 1.147-2.986) compared with those who were in the first, second and third years. Finally, students who practised self-medication were less likely to have good self-reported practice towards AMR (OR = 0.442, 95% CI: 0.278-0.702) compared with those who did not. Conclusions: This study demonstrated that non-healthcare students had moderate KAP regarding AMU and AMR. All university students should be provided with education about AMU and AMR through free short courses, seminars, workshops, and AMR and antimicrobial stewardship awareness campaigns.

Synthesis and compatibility evaluation of versatile mesoporous silica nanoparticles with red blood cells: an overview.

Protean mesoporous silica nanoparticles (MSNs) are propitious candidates over decades for nanoscale drug delivery systems due to their unique characteristics, including (but not limited to) changeable pore size, mesoporosity, high drug loading capacity, and biodegradability. MSNs have been drawing considerable attention as competent, safer and effective drug delivery vehicles day by day by their towering mechanical, chemical and thermal characteristics. Straightforward and easy steps are involved in the synthesis of MSNs at a relatively cheaper cost. This review reports Stober's synthesis, the first proposed synthesis procedure to prepare micron-sized, spherical MSNs, followed by other modifications later on done by scientists. To ensure the safety and compatibility of MSNs with biological systems, the hemocompatibility evaluation of MSNs using human red blood cells (RBCs) is a widely welcomed exercise. Though our main vision of this overview is to emphasize more on the hemocompatibility of MSNs to RBCs, we also brief about the synthesis and widespread applications of multifaceted MSNs. The strike of different parameters of MSNs plays a crucial role concerning the hemolytic activity of MSNs, which also has been discussed here. The inference is derived by centering some feasible measures that can be adopted to cut down or stop the hemolytic activity of MSNs in the future.
