RESUMO
BACKGROUND: Teachers constantly strive to obtain reliable and appropriate teaching and assessment methods to maximize the learning experience. This study aimed to introduce combined modified team-based learning and open-book exams (TBL/OBEs) as learning and assessment strategies in clinical biochemistry for medical students and assess students' perceptions. METHODS: Second-year medical students enrolled in the clinical biochemistry course were included in this study and subjected to TBL/OBE assessment. The assessment included two parts: the open-book format for half of the questions and the closed-book format for the other as a control. Upon completing the combined TBL/OBE session, the students were required to complete a structured survey to evaluate their perception of the experience. The data were gathered and analyzed. Data were presented as mean±standard error of the mean (SEM), and a p-value ≤0.05 was considered statistically significant. RESULTS: A total of 358 students completed the TBL/OBE and closed-book exam (CBE) and responded to the survey. Of these students, 76% preferred the OBE, and 84% thought it was a suitable learning method. On the one hand, the mean difficulty of the OBE format was 92.7±1.5 SEM, while, for the CBE, the mean difficulty was 88.7±1.9 SEM (p=0.015). On the other hand, the mean discrimination factor for OBE was 0.26±0.04 and, for the CBE, 0.41±0.04 SEM (p=0.0016). Males found the OBE questions easier (p=0.025) and less stressful (p=0.01). CONCLUSION: A combined model of modified TBL and OBE is a successful learning and assessment strategy in clinical biochemistry for medical students.
RESUMO
Background Gastroesophageal reflux disease (GERD) is one of the most common gastrointestinal tract diseases. Although there is a strong association between smoking and GERD, it is poorly understood until now. Electronic cigarettes (E-cigarettes) are widely used nowadays. So, our study aimed to investigate the prevalence of GERD among all Jeddah university students and its relation to E-cigarette smoking. Methodology A cross-sectional study was conducted among university students of all specialties in Jeddah, Saudi Arabia, using an online questionnaire to collect data distributed in a Google Form (Google LLC, Mountain View, California, United States) from August to November 2022. Results This study included 397 students, 36.5% of whom were from 18 to 20 years old, and the majority were females (69.3%). Of the participants, 43.8% were non-smokers, 13.1% were ex-smokers, and 43.1% currently smoked; of the last, 13.6% smoked tobacco cigarettes, 17.6% smoked hookah, and 35% were current E-cigarette smokers. The study found that among the participants, 19.9% had GERD based on the GerdQ, with females having a significantly higher percentage of GERD. A weak association was found between the prevalence of GERD and smoking cigarettes (p=0.49), hookah (p=0.988 ), and E-cigarettes (p=0.788 ) but this could be attributed to the high BMI. Conclusion E-cigarette smoking is more prevalent among university students in Jeddah than traditional cigarettes or hookah. However, there was no statistically significant link between E-cigarette smoking and GERD. High BMI could be a superadded factor.
