Assembly and performance of a cholera RDT prototype that detects both and associated bacteriophage as a proxy for pathogen detection.

Cholera rapid diagnostic tests (RDTs) are vulnerable to virulent bacteriophage predation. We hypothesized that an enhanced cholera RDT that detects the common virulent bacteriophage ICP1 might serve as a proxy for pathogen detection. We previously developed a monoclonal antibody (mAb) to the ICP1 major capsid protein.

Phage predation, disease severity and pathogen genetic diversity in cholera patients.

Despite an increasingly detailed picture of the molecular mechanisms of phage-bacterial interactions, we lack an understanding of how these interactions evolve and impact disease within patients. Here we report a year-long, nation-wide study of diarrheal disease patients in Bangladesh. Among cholera patients, we quantified (prey) and its virulent phages (predators) using metagenomics and quantitative PCR, while accounting for antibiotic exposure using quantitative mass spectrometry.

Open-label, randomised controlled trial found that a green banana mixed rice suji diet was most effective for persistent diarrhoea in children in Bangladesh.

Aim: Persistent diarrhoea continues for at least 14 days and kills more children than acute diarrhoea. We assessed whether rice suji, green banana mixed rice suji or 75% rice suji improved persistent diarrhoea in young children.

Methods: This open-labelled randomised controlled trial was carried out between December 2017 and August 2019 at the Dhaka Hospital of icddr,b, Bangladesh, with 135 children aged 6-35 months with persistent diarrhoea.

Genome-wide association studies reveal distinct genetic correlates and increased heritability of antimicrobial resistance in under anaerobic conditions.

The antibiotic formulary is threatened by high rates of antimicrobial resistance (AMR) among enteropathogens. Enteric bacteria are exposed to anaerobic conditions within the gastrointestinal tract, yet little is known about how oxygen exposure influences AMR. The facultative anaerobe was chosen as a model to address this knowledge gap.

Protocol for validation of the Global Scales for Early Development (GSED) for children under 3 years of age in seven countries.

Introduction: Children's early development is affected by caregiving experiences, with lifelong health and well-being implications. Governments and civil societies need population-based measures to monitor children's early development and ensure that children receive the care needed to thrive. To this end, the WHO developed the Global Scales for Early Development (GSED) to measure children's early development up to 3 years of age.

Chronic Aflatoxin Exposure and Cognitive and Language Development in Young Children of Bangladesh: A Longitudinal Study.

Aflatoxin can cross the blood-brain barrier, damage brain tissues, and have the potential to harm the development of the human brain. Although dietary aflatoxin exposure is common in children, there is a paucity of data on aflatoxin exposure and child developmental outcomes. The child's cognitive, motor, and language functions were assessed using the Bayley Scales of Infant and Toddler Development-III or BSID-III at the same time points.

Perception and experience of clinicians and caregivers in treating childhood severe pneumonia and hypoxemia using bubble continuous positive airway pressure in Ethiopian tertiary and general hospitals.

Background: In low and middle-income countries (LMICs), severe pneumonia with hypoxemia is the leading cause of child deaths, even with the provision of WHO-recommended antibiotic therapy, oxygen therapy and other supportive care. Previous studies found positive outcomes from the use of bubble continuous positive airway pressure (bCPAP) for treating these children compared to the standard oxygen therapy. Due to lack of data on the perceptions and experiences of hospital health care workers and caregivers of children on the feasibility and acceptability of bCPAP in treating children with severe pneumonia and hypoxemia in real-life settings, we examined these issues in tertiary and general hospitals in Ethiopia.

The influence of demographic and meteorological factors on temporal patterns of rotavirus infection in Dhaka, Bangladesh.

To quantify the potential impact of rotavirus vaccines and identify strategies to improve vaccine performance in Bangladesh, a better understanding of the drivers of pre-vaccination rotavirus patterns is required. We developed and fitted mathematical models to 23 years (1990-2012) of weekly rotavirus surveillance data from Dhaka with and without incorporating long-term and seasonal variation in the birth rate and meteorological factors. We performed external model validation using data between 2013 and 2019 from the regions of Dhaka and Matlab.
