Handling venomous snakes poses a significant risk of envenomation. In the case of spitting cobras, additional precautions, like wearing face shields, are necessary to prevent ophthalmic envenomation. Although, the Monocled Cobra (Naja kaouthia) is not a true spitting cobra, however some spitting events has been reported from Northeastern India and Nepal but ocular envenomation is scarce.

The antimalarial quinolines pyronaridine and chloroquine both inhibit hemozoin crystallization, predominately produced by intra-erythrocytic trophozoite stage parasites. Pyronaridine extends activity to ring-stage chloroquine-sensitive parasites, in contrast to chloroquine. Here, we investigated chloroquine and pyronaridine hemozoin inhibition type correlated to stage-specific activity on chloroquine-resistant ring-stage artemisinin sensitive and resistant CamWT and CamWT-C580Y parasites.

Article Synopsis
  • The COVID-19 pandemic significantly disrupted maternal health care services in Bangladesh, with notable declines in service utilization across the country compared to the pre-pandemic period from 2017 to 2019.
  • The study analyzed data from January 2017 to December 2021 to assess the trends in first antenatal visits, institutional deliveries, and caesarean sections, revealing about a 30% overall decrease in these services during the pandemic.
  • Geographical disparities were evident, with the Chattogram and Rajshahi divisions showing the lowest rates of maternal health service utilization, especially in 2020 and 2021, indicating a pronounced impact of the pandemic on specific regions.

Background: Assessing maternal health care utilisation is imperative for the health of both mother and her child. Maternal education is an important determinant in subsequent maternal health care usage, according to research. There is a dearth of research on the causal relationship between maternal education and maternal health services as well as examining the performance of different propensity score methods for estimating absolute effects.

Background: The rapid advancement of digital technologies, particularly in big data analytics (BDA), artificial intelligence (AI), machine learning (ML), and deep learning (DL), is reshaping the global health care system, including in Bangladesh. The increased adoption of these technologies in health care delivery within Bangladesh has sparked their integration into health care and public health research, resulting in a noticeable surge in related studies. However, a critical gap exists, as there is a lack of comprehensive evidence regarding the research landscape; regulatory challenges; use cases; and the application and adoption of BDA, AI, ML, and DL in the health care system of Bangladesh.

Background: The coronavirus disease 2019 (COVID-19) pandemic disrupted essential health care services worldwide, including those related to immunisation. National data from Bangladesh shows that child immunisation may have been adversely affected by the pandemic but regional evidence is limited. We therefore aimed to explore the regional differences in the indirect effects of COVID-19 on child immunisation in Bangladesh.

Accurate labeling of specific layers in the human cerebral cortex is crucial for advancing our understanding of neurodevelopmental and neurodegenerative disorders. Building on recent advancements in ultra-high-resolution ex vivo MRI, we present a novel semi-supervised segmentation model capable of identifying supragranular and infragranular layers in ex vivo MRI with unprecedented precision. On a dataset consisting of 17 whole-hemisphere ex vivo scans at 120 $\mu $m, we propose a Multi-resolution U-Nets framework that integrates global and local structural information, achieving reliable segmentation maps of the entire hemisphere, with Dice scores over 0.

Background: Worldwide, a significant number of girls become mothers during adolescence. In Bangladesh, adolescent childbirth is highly prevalent and has adverse effects on children's health and undernutrition. We aimed to identify the relationship between the undernutrition of children and adolescent motherhood, the factors associated with adolescent mothers' age at first birth, and to examine the programmatic factors and gaps influencing children's undernutrition in Bangladesh.

Background: Smoke from biomass fuels used for cooking in traditional cookstoves contains a variety of health-damaging pollutants. Inhalation of these pollutants by pregnant women has been linked to abnormal foetal development and adverse pregnancy outcomes, including low birthweight (LBW). There is a dearth of data on environmental interventions that have the potential to reduce exposure to biomass fuel during pregnancy and improve birth outcomes.

  • Bangladesh faces high maternal mortality due to delivery complications, particularly in hard-to-reach areas with limited healthcare access, motivating a study to assess contributing factors among mothers in these regions.
  • Data collected from 1,290 mothers in 13 sub-districts revealed that 32% experienced complications during delivery, with prolonged labour pain and obstructive labour being the most common issues.
  • The study found that higher education, more antenatal care visits, and being a first-time mother increased the likelihood of complications, while unnecessary caesarean deliveries were prevalent at private facilities.

Background: Infection prevention and control (IPC) is a critical component of delivering safe, effective and high-quality healthcare services, and eliminating avoidable healthcare-associated infections (HAIs) in health facilities, predominantly in population-dense settings such as Bangladesh.

Aim: Our study aimed to assess the effect of an integrated intervention package in improving the IPC level of the health facilities in Bangladesh.

Methods: We conducted a pre-post intervention study in six district hospitals (DHs) and 13 Upazila Health Complexes (UHCs) in the six districts of Bangladesh.

G-protein-coupled receptors (GPCRs) contribute to numerous physiological processes via complex network mechanisms. While indirect signaling assays (Ca mobilization, cAMP production, and GTPS binding) have been useful in identifying and characterizing downstream signaling mechanisms of GPCRs, these methods lack measurements of direct binding affinities, kinetics, binding specificity, and selectivity that are important parameters in GPCR drug discovery. In comparison to existing direct methods that use radio- or fluorescent labels, label-free techniques can closely emulate the native interactions around binding partners.

Background And Aim: Diabetes mellitus is a chronic, multi-factorial metabolic disorder and also an important public health issue that requires multi-dimensional therapeutic strategies for effective control. Unani herbs have long been used to effectively mitigate diabetes through various mechanisms. In recent years, it has been speculated that the alteration of gut microbiome ecology is potentially one of the important mechanisms through which the Unani drugs exert hypoglycemic action.

Three-dimensional (3D) printing, medical imaging, and implant design have all advanced significantly in recent years, and these developments may change how modern craniomaxillofacial surgeons use patient data to create tailored treatments. Polyether-ether-ketone (PEEK) is often seen as an attractive option over metal biomaterials in medical uses, but a solid PEEK implant often leads to poor osseointegration and clinical failure. Therefore, the objective of this study is to demonstrate the quantitative assessment of a custom porous PEEK implant for cranial reconstruction and to evaluate its fitting accuracy.
