With increasing antibiotic resistance in gram-negative bacteria, including those causing Shigellosis, evidence of safety and pharmacokinetics data on new oral antibiotics is crucial. We aimed to investigate the safety and pharmacokinetic properties of an oral carbapenem, tebipenem pivoxil, along with it's ability to produce desired results in childhood shigellosis. This randomized pilot clinical trial was conducted at Dhaka Hospital, icddr,b in 2022 between May and September.

Background: Bubble continuous positive airway pressure (bCPAP) is a low-cost, non-invasive respiratory support therapy for children with respiratory distress, but its effectiveness is dependent on the context. We aimed to understand contextual factors influencing bCPAP implementation for children aged 1-59 months in low-income and middle-income countries (LMICs) and to develop a theory explaining how these factors influence implementation outcomes.

Methods: In this realist review, we generated an initial programme theory comprising candidate context-mechanism-outcome configurations (CMOCs) via review of key references and team discussion.

A 7-month-old girl had been suffering from progressively deteriorating pneumonia despite getting multiple courses of broad-spectrum antibiotics as well as anti-fungal drugs for adequate duration. To find out the cause behind this deterioration, the patient underwent thorough clinical and relevant laboratory evaluation including chest radiology & imaging, screening for primary immune deficiency disorders (PID), cystic fibrosis, tuberculosis, invasive fungal pneumonia, congenital heart disease, covid pneumonia, TORCH etc. but failed to solve the mystery.

Background: Among diarrheal children, injudicious use of antibiotics is a major public health concern particularly in low- and middle-income countries. There are evidence-based guidelines by the World Health Organization (WHO) to prescribe antibiotics for bloody diarrhea in children. There is a scarcity of published data regarding the judicious use of antibiotics for bloody diarrhea in children.

Background: Air pollution exposure poses significant health risks for the general population, but particularly for women with acute and chronic respiratory conditions. Given the increasing global burden of air pollution-related illnesses, understanding these biomarkers is crucial for developing targeted interventions and improving respiratory health outcomes in vulnerable populations. In this systematic review, we aimed to determine potential dysregulated respiratory inflammatory blood biomarker candidates in adult female patients who experience varying levels and sources of inhaled pollutant exposure.

Article Synopsis
  • The study investigates the differences in lactate levels between diarrheal patients suffering from septic shock and hypovolemic shock after they receive their first fluid resuscitation.
  • Septic shock and hypovolemic shock both lead to low blood pressure and organ dysfunction, but they have different underlying causes, necessitating accurate diagnosis.
  • Conducted over 19 months at Dhaka Hospital, the research involved critically ill adults, measuring lactate levels using StatStrip Lactate meters to potentially improve bedside testing and diagnosis for these serious conditions.

Sepsis is the leading cause of child death globally with low- and middle-income countries (LMICs) bearing a disproportionate burden of pediatric sepsis deaths. Limited diagnostic and critical care capacity and health worker shortages contribute to delayed recognition of advanced sepsis (severe sepsis, septic shock, and/or multiple organ dysfunction) in LMICs. The aims of this study were to 1) assess the feasibility of a wearable device for physiologic monitoring of septic children in a LMIC setting and 2) develop machine learning models that utilize readily available wearable and clinical data to predict advanced sepsis in children.

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) 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.

Article Synopsis
  • About 12% of diarrhoeal cases last 7-13 days, termed prolonged diarrhoea, which is linked to the majority of diarrhoeal deaths in young children.
  • The study evaluated young children (2-23 months) with acute (<7 days) and prolonged (≥7-13 days) diarrhoea using data from a large trial conducted across seven countries in Asia and sub-Saharan Africa between 2017 and 2019.
  • Findings showed that prolonged diarrhoea was associated with factors like younger age, larger family size, maternal illiteracy, moderate underweight, and the presence of certain pathogens, with significant implications for children's health outcomes at a 90-day follow-up.

Background: Sepsis is a leading cause of paediatric mortality worldwide, disproportionately affecting children in low- and middle-income countries. The impacts of climate change on the burden and outcomes of sepsis in low- and middle-income countries, particularly in paediatric populations, remain poorly understood. We aimed to assess the associations between climate variables (temperature and precipitation) and paediatric sepsis incidence and mortality in Bangladesh, one of the countries most affected by climate change.

Background: Global influenza-associated acute respiratory infections contribute to 3-5 million severe illnesses requiring hospitalization annually, with 90% of hospitalizations occurring among children < 5 years in developing countries. In Bangladesh, the inadequate availability of nationally representative, robust estimates of influenza-associated hospitalizations limits allocation of resources for prevention and control measures.

Methods: This study used data from the hospital-based influenza surveillance (HBIS) system in Bangladesh from 2010 to 2019 and healthcare utilization surveys to determine hospital utilization patterns in the catchment area.

Article Synopsis
  • The study evaluates the implementation of a standardized register developed by Bangladesh’s National Newborn Health and IMCI program, aimed at improving care for newborns and children under five in hospitals.
  • Implementation research was conducted in two district and two sub-district hospitals in Kushtia and Dinajpur from November 2022 to January 2023, focusing on usability, acceptability, adoption, fidelity, and utility of the register.
  • Results showed good usability (73) and acceptability (82) scores among healthcare providers, with high adoption rates (96%) for children's admissions; however, fidelity was lower for certain data elements, notably investigations completed (24%).
