Insights

Diarrhoea temporarily impacts growth in young Bangladeshi children. However, children recover from non-bloody diarrhoea, suggesting long-term nutritional status is unlikely to improve through diarrhoea control alone.

Area of Science:

  • Child Health
  • Nutritional Science
  • Pediatrics

Background:

  • Diarrhoea is a significant health concern for children in developing countries.
  • Understanding the long-term impact of diarrhoea on child growth is crucial for public health interventions.

Purpose of the Study:

  • To examine the relationship between diarrhoea history and growth in rural Bangladeshi children aged 6-35 months.
  • To determine if growth deficits following diarrhoea are transient or persistent.

Main Methods:

  • Analysis of 1772 3-month intervals of child growth data.
  • Comparison of weight gain and linear growth in intervals with and without diarrhoea.
  • Assessment of catch-up growth following non-bloody diarrhoea episodes.

Main Results:

  • Children experienced lower weight gain and linear growth during intervals with diarrhoea.
  • Deficits in weight and height gain were not apparent a few weeks after non-bloody diarrhoea episodes.
  • Catch-up growth was observed after non-bloody diarrhoeas.

Conclusions:

  • The impact of diarrhoea on child growth appears to be transient.
  • Efforts focused solely on diarrhoea control may not significantly improve long-term nutritional status in this population.
  • Further research into other factors affecting child nutrition is warranted.

Fungal Phylum Microsporidia

Microsporidia are a group of obligate intracellular fungi that were initially classified as protists but were later reclassified based on phylogenetic, molecular, and structural evidence linking them to the Chytridiomycota. These unicellular, non-motile organisms are highly specialized parasites that infect a wide range of animal hosts, including humans. They have evolved extensive genomic and metabolic reductions, making them highly dependent on their hosts for survival.Morphology and Genomic...

Development of Human Microbiota

The human microbiota begins developing at birth and undergoes continual change as we age. Infancy marks a critical period of microbial sensitivity, offering a “window of opportunity” during which beneficial microbes help mature the immune system. By age three, children typically develop a more stable and diverse microbial community. Newborns acquire microbes from their immediate environment; vaginal delivery favors maternal vaginal microbes, while cesarean births favor microbes from the skin...
Cholera01:25

Cholera

Cholera is an acute gastrointestinal disease caused by the Gram-negative bacterium Vibrio cholerae. It is transmitted primarily via the fecal-oral route through the ingestion of contaminated water or food.Vibrio cholerae is a motile, Gram-negative bacterium of the family Vibrionaceae, primarily associated with waterborne outbreaks in areas with inadequate sanitation. Although over 200 serogroups of V. cholerae exist, only O1 and O139 are responsible for epidemic cholera. The O1 serogroup,...
