Introduction: The menstrual cycle involves a sequence of structural, functional, and hormonal changes in the reproductive system. This is linked and controlled by cyclical fluctuations in the levels of FSH, LH, estrogen, and progesterone. Because of these cyclical fluctuations, there might also be associated cyclical changes of magnesium and systemic arterial blood pressures during the menstrual cycle. Purpose: To assess the changes in serum magnesium level and systemic arterial blood pressures during the menstrual cycle in young reproductive women. Methodology: the sample population is 40 apparently healthy young reproductive-aged 18- 25years female students from the University of Medicine, Magway participated in this study. Systemic arterial blood pressures were measured by indirect method. The serum magnesium level was measured by spectrophotometry. These measurements were done in the early follicular phase (EF), the peri-ovulatory phase (PO), and the mid-luteal phase (ML) of the menstrual cycle. The serum magnesium levels were significantly (p <0.001) lower, and the systolic blood pressures were significantly higher (p <0.05) in the PO than the EF and the ML. In the EF, there was a significant negative correlation between serum magnesium level and diastolic blood pressure (r= -0.374, p <0.05) and mean arterial pressure (r = -0.354, p < 0.05) but no significant correlation with systolic blood pressure. In the PO, there was no significant correlation between serum magnesium level and systemic arterial blood pressures. In the ML, there was significant negative correlation between serum magnesium level and systolic blood pressure (r = -0.651, p <0.001), diastolic blood pressure (r = -0.607, p <0.001), and mean arterial pressure (r = -0.661, p <0.001). Conclusion: The study concludes that serum magnesium level has a negative effect on blood pressure changes and the blood pressure-lowering effect of magnesium. These changes are related to the fluctuation of estrogen levels during the menstrual cycle.

Introduction: In modern medical education, with its transformational changes, teacher-centered learning is transformed into student-centered learning. This shift has escalated so fast with momentum, and its value in teaching and learning has been evaluated in many ways. In the current scenario, problem-based learning (PBL) is a well-recognized effective method of teaching and learning. The credit goes to McMaster University in Hamilton, Ontario, Canada, for the establishment of PBL. In Malaysia, many medical schools have applied this method in their curriculum, one of which is University Malaysia, Sarawak (UNIMAS), which has also adopted PBL in its undergraduate curriculum since 1996. Purpose: The aim of this study is to determine the students’ acceptance of PBL and its positive and negative impact on their learning. Methodology: It was a cross-sectional study conducted to determine the acceptance of the students of PBL. The study population is selected using convenience sampling of 140 out of 148 pre-clinical year-2 students who were exposed to the PBL method, the focus group discussion (FGD) was conducted based on pre-framed questions to know the impact of PBL on the students’ learning. Results: Results showed that the respondents had the satisfaction and accepted PBL. Sixty students from 6 PBL groups were involved in FGD. Feedback from FGD revealed their difficulties with the conduction of 1st session of PBL, for instance, problems in searching resources, new learning environments and peers from different regions. There were positive responses spelled by the subjects that the PBL has improved their communication skills, critical thinking, and self-esteem. Conclusion: Overall the PBL has proved beneficial evidenced a positive impact on the learning process of medical students.Keywords
