MATERIALS & METHODS: An indirect in vitro coculture model of injured airway epithelium explant with MSCs was developed. LC-MS/MS analysis was performed to determine factors secreted by MSCs and their involvement in epithelium repair was evaluated by histopathological assessment.
RESULTS: The identification of 54 of MSC proteins of which 44 of them were secretory/extracellular proteins. 43 of the secreted proteins were found to be involved in accelerating airway epithelium repair by stimulating the migratory, proliferative and differentiation abilities of the endogenous repair mechanisms. MSC-secreted proteins also initiated epithelial-mesenchymal transition process during early repair.
CONCLUSION: MSC-secreted factors accelerated airway epithelial repair by stimulating the endogenous reparative and regenerative ability of lung cells.
Methods: A retrospective study was conducted among patients with hyperthyroidism who received RAI therapy at Nuclear Medicine Clinic, Hospital Universiti Sains Malaysia (HUSM), Kelantan. Data regarding patients' demographics, gender, aetiology of hyperthyroidism, presence of autoantibodies, dose of RAI used and usage of antithyroid drug post RAI therapy were included in the analysis.
Results: Of a total of 167 screened patients, 137 subjects were eligible for this study. The incidence of hypothyroidism within one year of RAI therapy was 32.9%. Women were found to be less likely to develop hypothyroidism post RAI therapy (adjusted odds ratio, 0.406; 95% confidence interval: 0.181-0.908; p = 0.028). The usage of antithyroid drug post RAI was significantly associated with a lower incidence of hypothyroidism post RAI therapy (adjusted odds ratio, 0.188; 95% confidence interval: 0.081-0.438; p<0.001).
Conclusion: This study showed a high incidence of hypothyroidism within one-year post RAI therapy. Gender and usage of antithyroid drug post RAI therapy are significantly associated with the development of hypothyroidism.
Methods: A qualitative phenomenological study was conducted on a group of Universiti Sains Malaysia medical students who had finished the Community and Family Case Study (CFCS) program. Data were gathered through focused group discussions and student reflective journals. Participants were sampled using the maximal variation technique of purposive sampling. Three steps of thematic analysis using the Atlasti software were employed to identify categories, subthemes, and themes.
Results: Personal, role, social, and research identities were generated that contribute to the PID of medical students through the CFCS program. The results indicate that the CFCS program nurtured personal identity through the development of professional skills, soft skills, and personal values. Pertaining to role identity, this is related to patient care in terms of primary care and interprofessional awareness. Pertaining to social identity, the obvious feature was community awareness related to culture, society, and politics. A positive outcome of the CFCS program was found to be its fostering of research skills, which is related to the use of epidemiology and research methods.
Conclusion: The findings indicate that the CFCS program promotes PID among medical students. The current data highlight and provide insights into the importance of integrating CBE into medical curricula to prepare future doctors for their entry into the profession.
