The effectiveness of community-based interprofessional education for undergraduate medical and health promotion students.

BACKGROUND: Community-based interprofessional education (CBIPE) has been proven effective in enhancing the interprofessional competencies of medical and health professional students. However, there is a lack of evaluation on the impact of experiential CBIPE among undergraduate medical and health promotion students in Thailand. Therefore, the objective of this study is to assess the influence of CBIPE learning on the collaborative competencies of these students. METHODS: A one-group pre-posttest design in 193 (152 medical students and 41 health promotion) students were involved in the CBIPE program, later divided into 12 groups. Data was collected by direct observations of mentors using the Interprofessional Collaborative Competencies Attainment Survey (ICCAS). The Wilcoxon matched-pairs signed-rank test was conducted to evaluate the effectiveness of the CBIPE program. RESULTS: A total of 175 (90.67%) completed ICCAS and satisfaction questions before and after the CBIPE program. The mean age of respondents was 20.29 ± 1.63 years; 60.57% were women and 39.43% were men. The results showed a significant increase in collaborative competencies before and after the 2-week course. Gender-stratified analysis showed an improvement after CBIPE training for all subscales in women, while the communication, collaboration, conflict management, and functioning team skills segment score was significantly higher in the post-assessment among men. CONCLUSION: The implementation of CBIPE learning was successful in enhancing collaborative competencies among both medical and health promotion students. These findings will provide valuable insights for the design and improvement of CBIPE learning programs in other universities.

A novel method to derive amniotic fluid stem cells for therapeutic purposes.

BACKGROUND: Human amniotic fluid stem (hAFS) cells have become an attractive stem cell source for medical therapy due to both their ability to propagate as stem cells and the lack of ethical debate that comes with the use of embryonic stem cells. Although techniques to derive stem cells from amniotic fluid are available, the techniques have limitations for clinical uses, including a requirement of long periods of time for stem cell production, population heterogeneity and xeno-contamination from using animal antibody-coated magnetic beads. Herein we describe a novel isolation method that fits for hAFS derivation for cell-based therapy. METHODS AND RESULTS: With our method, single hAFS cells generate colonies in a primary culture of amniotic fluid cells. Individual hAFS colonies are then expanded by subculturing in order to make a clonal hAFS cell line. This method allows derivation of a substantial amount of a pure stem cell population within a short period of time. Indeed, 108 cells from a clonal hAFS line can be derived in two weeks using our method, while previous techniques require two months. The resultant hAFS cells show a 2-5 times greater proliferative ability than with previous techniques and a population doubling time of 0.8 days. The hAFS cells exhibit typical hAFS cell characteristics including the ability to differentiate into adipogenic-, osteogenic- and neurogenic lineages, expression of specific stem cell markers including Oct4, SSEA4, CD29, CD44, CD73, CD90, CD105 and CD133, and maintenance of a normal karyotype over long culture periods. CONCLUSIONS: We have created a novel hAFS cell derivation method that can produce a vast amount of high quality stem cells within a short period of time. Our technique makes possibility for providing autogenic fetal stem cells and allogeneic cells for future cell-based therapy.
