Thalassemia poses a major public health concern in Bangladesh with a high prevalence of carriers. However, there is a substantial knowledge gap regarding its epidemiology, clinical aspects, and treatment outcomes. Despite its high prevalence, there is a notable lack of awareness regarding thalassemia in the Bangladeshi population. The absence of precisely validated data impedes a comprehensive understanding of this disease. Premarital thalassemia screening is reportedly a successful strategy for countries such as Saudi Arabia and Iran and has also been proposed for Bangladesh. Mandatory screening coupled with genetic counseling is promising for reducing the prevalence of thalassemia by identifying carriers and providing relevant health education. However, sociocultural barriers, challenges, financial constraints, and health risks associated with prenatal diagnosis and abortion could hinder the success of such programs. Positive outcomes from other countries underscore the effectiveness of such programs in reducing thalassemia incidence. The early identification of carriers and genetic counseling can significantly reduce the burden of thalassemia. Additionally, the strain on the healthcare system would be eased, and the quality of life of thalassemia patients would be improved. In conclusion, based on evidence mandatory premarital screening with genetic counseling could be an effective measure to reduce the prevalence of thalassemia in Bangladesh. Leveraging positive attitudes, adopting successful international models, and addressing existing challenges are crucial for the successful implementation of programs that contribute to the overall health and well-being of the country's population.

Background: Dengue is a major public health concern in Bangladesh. This study aimed to assess the perceptions and practices of community members in Dhaka regarding community engagement and social participation for dengue prevention. Methods: A cross‐sectional online survey was conducted in Dhaka City from May 2022 to December 2022. The respondents were randomly selected. The association between community participation and prevention practices was tested using the χ2 test. Results: The findings of this study indicate that the majority of participants (92%) believed that community effort would be relied upon in the event of a dengue outbreak. Environmental cleaning campaigns were the preferred approach, and religious leaders viewed them positively. This study also revealed significant variations in knowledge levels, with those involved in community efforts and mass gatherings demonstrating greater knowledge. This study sheds light on the demographic factors that influence dengue knowledge and provides valuable insights into the development of targeted public health interventions. Conclusion: The study revealed negative perceptions and limited participation in dengue prevention among participants, with the majority demonstrating a poor understanding of preventive measures. While some showed positive attitudes towards community engagement, significant disparities existed in participation, highlighting the need for targeted educational campaigns and enhanced community mobilization efforts. Moreover, the importance of multisectoral collaboration is emphasized, underscoring the need for coordinated efforts among health departments, NGOs, religious institutions, and community leaders to effectively combat dengue transmission. Recommendations include ongoing educational initiatives, targeted interventions to promote community involvement, and fostering collaboration across sectors to strengthen dengue prevention efforts and to safeguard public health.

• Interleukin (IL)-4 and IL-6 levels along with erythrocyte sedimentation rate (ESR); neutrophil count; and the levels of ferritin, C-reactive protein (CRP), and D-dimer were significantly increased however, interferon (IFN)-γ levels were significantly reduced in patients with severe coronavirus disease 2019 (COVID-19) compared with those in patients with mild and/or moderate COVID-19. • The white blood cell (WBC), lymphocyte, eosinophil, and platelet counts are significantly reduced in patients with severe COVID-19 in comparison with those in patients with mild and moderate COVID-19 symptoms. • The neutrophil-to-lymphocyte ratio (NLR), IL-6-to-lymphocyte ratio, platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR), and ferritin-to-ESR ratio are also significantly higher in patients with severe COVID-19 than in those with mild and/or moderate COVID-19. • The reduced level of IFN-γ is attributed to a less fatality toll in Bangladesh. The manifestation of coronavirus disease 2019 (COVID-19) severity and mortality has been associated with dysregulation of the immune response, often influenced by racial disparities and conferred by changes in hematologic and immunologic parameters. These biological and hematologic parameters as well as cytokine profiles were investigated in a cohort of 61 COVID-19-positive patients (categorized into mild, moderate, and severe groups) from Bangladesh using standard analytical methods. The data reported that the interleukin (IL)-4 and IL-6 levels were significantly increased, whereas the levels of interferon (IFN)-γ were significantly reduced in patients with severe COVID-19 (p < 0.05) compared with those in patients with mild and/or moderate COVID-19. The extent of erythrocyte sedimentation rate (ESR); neutrophil count; and levels of ferritin, C-reactive protein (CRP), and D-dimer (p < 0.05) were found to be significantly increased, whereas the white blood cell (WBC), lymphocyte, eosinophil, and platelet counts (p < 0.05) were observed to be significantly reduced in patients with severe COVID-19 compared with those in the patients in other 2 groups. Our study exhibited a significantly higher IL-6-to-lymphocyte ratio in patients with severe COVID-19 than in those with mild and moderate COVID-19. The calculated neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR), and ferritin-to-ESR ratio were significantly increased in patients with severe COVID-19. The increase in the IL-4 and IL-6 levels along with CRP and D-dimer levels may envisage a hyperinflammatory environment and immune dysregulation, which contribute to prolonged viral persistence, leading to severe disease. However, the reduced level of IFN-γ can be attributed to a less fatality toll in Bangladesh compared with that in the rest of the world. [ABSTRACT FROM AUTHOR]
