Biodegradable
polymers are largely employed in the biomedical field,
ranging from tissue regeneration to drug/vaccine delivery. The biodegradable
polymers are highly biocompatible and possess negligible toxicity.
In addition, biomaterial-based vaccines possess adjuvant properties,
thereby enhancing immune responses. This Review introduces the use
of different biodegradable polymers and their degradation mechanism.
Different kinds of vaccines, as well as the interaction between the
carriers with the immune system, then are highlighted. Natural and
synthetic biodegradable micro-/nanoplatforms, hydrogels, and scaffolds
for local or targeted and controlled vaccine release are subsequently
discussed.
Background: Familiarity with and management of drugs side-effects are among nurses’ main educational needs with respect to pharmacological care in psychiatry departments. This study aimed to determine the effects of psychoactive drugs education through mobile phone and group discussion on nursing students’ attitude, satisfaction, and learning.Methods: This interventional study was done in Shiraz University of Medical Sciences in 2018. The participants included 40 nursing students passing the mental health apprenticeship in their 6 th educational semester. The 32 students with inclusion criteria were randomly divided into two groups each containing 16 subjects. The first group underwent the educational intervention through group discussion within the first two weeks of apprenticeship. The second group, on the other hand, received the educational intervention through mobile phones over the second two weeks of the course. The students’ learning, attitude, and satisfaction were assessed before and two weeks after the intervention and were compared two groups. After all, the data were entered into the SPSS statistical software, version 16 and were analyzed using descriptive and inferential (paired and independent t-test) statistics. P<0.05 was considered to be statistically significant.Results: The results showed a significant difference in the two groups’ rate of learning before and after the intervention (p=0.00). However, no significant difference was found between the two groups in this regard (p=0.158). The results also revealed a significant difference in the two groups’ satisfaction with the instruction method before and after the intervention. A significant difference was also observed between the two groups in this regard (p=0.043). Finally, the results indicated that the students in the mobile phone group developed a significantly more positive attitude after the intervention compared to baseline (p=0.038).Conclusions: The study results demonstrated that mobile teaching methods could be effective in students’ learning, satisfaction, and attitude. Thus, further studies are recommended to be conducted on other medical and nursing apprenticeships, so that such methods can be used in clinical education in case of obtaining similar results.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
