Rebalancing of mitochondrial homeostasis through an NAD+ – SIRT1 pathway preserves intestinal barrier function in severe malnutrition
Abstract Background The intestine of children with severe malnutrition (SM) shows structural and functional changes that are linked to increased infection and mortality. SM dysregulates the tryptophan-kynurenine pathway, which may…

Minimally invasive post-mortem intestinal tissue sampling in malnourished and acutely ill children is feasible and informative
Abstract Background Intestinal disorders such as environmental enteric dysfunction (EED) are prevalent in low- and middle-income countries (LMICs) and important contributors to childhood undernutrition and mortality. Autopsies are rarely…

The role of albumin and the extracellular matrix on the pathophysiology of oedema formation in severe malnutrition.
Background While fluid flows in a steady state from plasma, through interstitium, and into the lymph compartment, altered fluid distribution and oedema can result from abnormal Starling's forces, increased endothelial…
