Background: Globally, 10% of pregnant women and 13% of postpartum women experience mental disorders. In Bangladesh, nearly 50% of mothers face common mental disorders, but mental health services and trained professionals to serve their needs are scarce. To address this, the government of Bangladesh's Non-Communicable Disease Control program initiated "Wellbeing Centers," telemental health services in selected public hospitals.

The present work describes the synthesis of WO-BiVO-nanoflakes heterostructure (NFHs) by a single step hydrothermal method. The analysis of crystalline phases and structural behavior deduced the formation of good crystal quality WO-BiVONFHs. Under microscopic observation, the as-prepared WO-BiVOdisplayed uniform and conspicuous nanoflakes like structures.

The photovoltaic performance of inverted perovskite solar cells (PSCs) relies on effectively managing the interface between the hole extraction layer and the light-absorbing perovskite layer. In this study, we have synthesised (4-(3,6-bis(methylthio)-9H-carbazol-9-yl)butyl)phosphonic acid (MeS-4PACz), which forms a self-assembled monolayer (SAM) on the fluorine-doped tin oxide (FTO) electrode. The molecule's methylthio substituents generate a favourable interfacial dipole moment and interact with the perovskite layer.

Article Synopsis
  • This study investigates the perceptions and practices of healthcare providers regarding delayed cord clamping (DCC) in Bangladesh, highlighting benefits and challenges of the procedure.
  • Healthcare providers generally support DCC, suggesting clamping should occur between one to three minutes post-delivery, influenced by international research and training.
  • Observations revealed inconsistency in clamping practices, with immediate clamping in caesarean sections and a lack of standard guidelines, compounded by cultural influences and resource constraints.

Article Synopsis
  • - The text discusses the issue of microplastics (MPs), particularly polyvinyl chloride (PVC), which contaminate rivers and oceans and threaten human health, highlighting the need for effective detection methods.
  • - A two-step hydrothermal process was used to synthesize porous NiMoO nanotubes (NTs) from MoO nanorods (NRs), ensuring effective detection of PVC MPs due to their structural and hydrophobic properties.
  • - The electrochemical detection of PVC MPs using the porous NiMoO NTs demonstrated effective sensitivity and performance, indicated by a low limit of detection (LOD) and strong sensing response at low concentrations.

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: Areca nut (AN) and AN products (ANPs) are commonly used as psychoactive substances with marked dependence potential. Scant information exists on the Indian mental health professionals' (MHPs) knowledge of AN-ANPs, attitude toward AN-ANP use/users, and behavior regarding their clients' AN-ANP use. To address this gap, a survey was undertaken to assess MHPs' knowledge, attitudes, and behavioral responses toward AN-ANP use and addiction.

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.

Background: The coronavirus disease 2019 (COVID-19) had a profound impact worldwide. In Bangladesh, the official number of deaths for COVID-19 was around 29 000. However, many countries including Bangladesh experienced substantial underreporting of COVID-19 deaths due to lack of complete national civil registration system.

Background: Cystic echinococcosis mainly affects the liver and lungs, in which the larvae from the microvascular wall in the liver pass to the lungs and then to the blood circulation and settle in any tissue or organ.

Objectives: The objective of this study was to report the unusual location of hydatid cysts in infected patients in Sulaimaniyah City, Iraq.

Patients And Methods: This retrospective case series study enrolled 13 patients.

Article Synopsis
  • The hypothalamus in mammals regulates key survival and reproductive functions and has distinct interconnected sub-regions whose spatial organization is still not fully understood.
  • One hypothesis is that the structural connectivity of these sub-regions allows for efficient functioning by placing well-connected areas closer together, minimizing the distance for axonal signals.
  • Research using data from the Allen Mouse Brain Connectivity Atlas shows that while the overall distances between these sub-regions aren't minimized, factoring in connectivity reveals that the hypothalamus is highly efficient, ranking in the top 94th percentile for neural efficiency compared to random configurations.

Metal-organic frameworks (MOFs) have emerged as promising materials for triboelectric nanogenerators (TENGs), but the effects of ligand choice on triboelectric charge remain underexplored. Hence, this paper demonstrates the effect of single, binary, and ternary ligands on TENG performance of cobalt/cerium-based (Co─Ce) bimetallic MOFs utilizing 2-methylimidazole (2Melm), terephthalic acid (BDC), and benzene tricarboxylic acid (BTC) as ligands. The detailed structural characterization revealed that varying ligand chemistries led to distinct MOF features affecting TENG performance.

The intermediate filament (IF) protein vimentin is associated with many diseases with phenotypes of enhanced cellular migration and aggressive invasion through the extracellular matrix (ECM) of tissues, but vimentin's role in in-vivo cell migration is still largely unclear. Vimentin is important for proper cellular adhesion and force generation, which are critical to cell migration; yet the vimentin cytoskeleton also hinders the ability of cells to squeeze through small pores in ECM, resisting migration. To identify the role of vimentin in collective cell migration, we generate spheroids of wide-type and vimentin-null mouse embryonic fibroblasts (mEFs) and embed them in a 3D collagen matrix.

Article Synopsis
  • 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.
