Background: Dengue fever is a significant global health concern, particularly in tropical and subtropical regions, including Bangladesh. Hematocrit levels play a crucial role in monitoring plasma leakage and disease severity in Dengue patients. This study aims to observe the hematocrit levels and other hematological parameters among Dengue fever patients admitted to a tertiary care hospital. Methods: This cross-sectional observational study was conducted at Tairunnessa Memorial Medical College Hospital from March 2022 to August 2022. A total of 80 confirmed Dengue patients were included in the study. Daily hematocrit levels, hemoglobin levels, and white blood cell counts were recorded over a 10-day monitoring period. Data analysis included descriptive statistics to assess trends and variations in these hematological parameters. Result: The majority of participants (27.5%) belonged to the 18-27 years age group, with a nearly equal gender distribution (52.5% males, 47.5% females). Dengue fever with and without warning signs accounted for 93.75% of cases, while severe Dengue was observed in only 6-25% of cases. Fever was present in all patients, with headache (65%) and myalgia (47.5%) being the most common associated symptoms. The mean hematocrit level peaked on Day 3 (47.58±5.22%) before progressively declining, while hemoglobin levels followed a similar trend, peaking on Day 3 (16.02±1.92 g/dL) and reaching the lowest on Day 9 (12.82±1.42 g/dL). White blood cell counts declined until Day 4 (3333.52±24.11 per cu.mm) and then showed a gradual increase. Recovery was observed in 93.75% of cases, with a mortality rate of 1.25%. Conclusion: The study highlights the importance of monitoring hematocrit and other hematological parameters in Dengue fever patients for early detection of complications and effective management. While the majority of cases were Dengue fever with and without warning signs; the observed hematological trends underscore the need for vigilant monitoring to prevent severe outcomes. Further large-scale studies are warranted to strengthen clinical guidelines for Dengue management.

Background: Interactive teaching strategies have been shown to enhance student engagement and learning outcomes in medical education. However, the extent to which first-year medical students in Bangladesh perceive interactivity in lectures remains unclear. This study aimed to assess students’ perceptions of interactivity in General Embryology lecture classes. Objectives: To analyze the perceptions of Bangladeshi medical undergraduates regarding interactivity in the General Embryology lecture classes Methods: In this study two surveys were conducted on 232 undergraduates of two medical colleges of Bangladesh using a questionnaire designed by the researcher to analyze the perceptions of the undergraduates regarding how the lecturers try to make their General Embryology lectures ‘understandable and interesting’. Results: The survey results regarding the perceptions and views of the medical undergraduates show that out of the 55 questions regarding interactivity, the Embryology lectures scored three (3) or more out of four (4) in case of only two (2) of the questions. Two (2) or more was obtained in case of eighteen (18) questions only. Conclusions: These results broadly suggest lower levels of interactivity regarding General Embryology lecture classes in the eyes of Bangladeshi medical undergraduates.

This study involves the use of the histology of the mantle of a periwinkle species, Tympanotonus fuscatus, as a biomarker tool, to investigate and evaluate the ecological pollution status of two different water bodies, Bodo and Creek Road water-sides, in River State. The study involved the sampling of ten (10) feral table sized fish from two stations along the creeks of the experimental sites (Bodo and Creek Road water bodies), with similar specie, size and number from a reference site (ARAC – African Aqua-culture Centre). The test fish mantles were harvested from the fish caught from both experimental sites for histological evaluation, while the control mantles were harvested from fish harvested from ARAC. The percentage prevalence of histological alterations showed that fish from Bodo water-body had the worse outcome (25%), followed by Creek Road water-body (21.7%) and ARAC having the best outcome (6.6%). mantle histology has proven to be an explorable biomarker for evaluation of environmental status.
