Students' Perception of Educational Environment of Medical Colleges in Bangladesh

Background: Students' perceptions of their educational environment are a useful basis for modifying and improving the quality of educational environment. Educational environment is one of the most important factors determining the success of an effective curriculum. The quality of educational environment has been identified to be crucial for effective learning. Identifying the weakness of educational environment and understanding how students perceive the environment will help the institute to facilitate learning and to achieve better learning outcome. Objective: To explore students' perceptions of their educational environment and to find out gender differences in perception. Methods: It was a cross sectional descriptive study. Dundee Ready Education Environment Measure (DREEM) inventory was administered to 1903 medical students (studying in 3rd, 4th and 5th year MBBS course) in 15 medical colleges of Bangladesh adopting purposive sampling. Results: The total mean score for all students was found positive (110/200). Students' perceptions of learning was positive (28/48), perceptions of teachers was moving in right direction (24/44), students academic self perception was positive (19.5/32). Students' perceptions of atmosphere was expressed as many issues need to change (24/48) and social self perceptions was not a nice place (14/28). Female students’ perceptions were significantly higher than male students. Conclusion: Remedial measure should be needed in the subscales of students’ perceptions of atmosphere and social self perceptions for further improvement. Findings from this study may give guideline to curricular planner and faculties/administrators of medical college for further improvement of educational environment.

The evaluation between vitamin D level and pelvic organ prolapse in post-menopausal women

Background: Vitamin D is important for skeletal integrity and optimal muscle function. The high incidence and prevalence of vitamin D deficiency and pelvic organ prolapse have been found in postmenopausal women, raising the question of whether the entities are related. The aim of the study was to evaluation between vitamin D level and pelvic organ prolapse in post-menopausal women. Methods: This case control study has been designed and conducted in the Department of Obstetrics and Gynecology, BSMMU to investigate the level of vitamin D in patients with and without pelvic organ prolapse to explore the association of vitamin D with pelvic organ prolapse. After taking informed written consent the serum vitamin D level of all participants was measured by CMIA technology with flexible assay protocols at Biochemistry and Molecular Biology department of the same institute. Statistical analysis of the results was obtained by using window-based computer software devised with Statistical Packages for Social Sciences (SPSS-24). Results: The study population was divided into two groups, a case group (n=74) consisting of patients with pelvic organ prolapse and a control group (n=74) comprising of women without pelvic organ prolapse. A total 148 participants of 52 years or older attending the out or inpatient department were enrolled in the study. Mean±SD level of Vitamin D in the case group was 13.96±5.18 ng/ml and in the control, group was 21.08±5.77 ng/ml respectively. The difference was statistically significant (p<0.05). Moreover, the vitamin D levels were inversely proportionate with the severity of pelvic organ prolapse. Conclusions: Vitamin D deficiency may be an important systemic factor associated with pelvic organ prolapse. Measuring vitamin D levels in postmenopausal women and replenishing deficiencies may also be important for the pelvic floor

Influence of multiple showering on quality of buffalo semen during hot-humid season

Objectives: This experiment was conducted on buffaloes to see effect of showering on maintaining good quality of buffalo semen in hot season. Materials and methods: This study was conducted on 6(six) indigenous buffalo bulls in hot summer of March and April 2017. The effect of multiple showering vs single shower alone on fresh and equilibrated semen quality was observed. The buffalos were divided into similar two groups (according to age and weight) and housed in half-walled openshed with adequate spacing and the feeding management being identical. The bulls in the control group were allowed to a single shower at 10.00 am and experimental bulls were allowed to four showers at 07.00, 10.00, 13.00 and 16.00. Temperature and humidity were recorded during this time. The average temperature was around 35°C along with 72% relative humidity. The quality of experimental bulls semen was evaluated in terms of volume, live sperm, sperm concentration, sperm motility, motion parameters and morphology for normal and abnormal sperm. For this analysis Computer Assisted Semen Analysis (CASA) system was used. Results: Between experimental group and control group semen quality differs significantly for volume (2.04±0.13 mL; 2.53±0.27 mL) (P [J Adv Vet Anim Res 2018; 5(1.000): 12-18
