Abstract

Not Just Wasting: Malnutrition is well known in Malawi, including a severe form—kwashiorkor—in which children do not simply waste away, they also suffer edema, liver damage, skin ulceration, and anorexia. Smith et al. (p. 548 ; see the Perspective by Relman ) investigated the microbiota of pairs of twins in Malawian villages and found notable differences in the composition of the gut microbiota in children with kwashiorkor. In these children, a bacterial species related to Desulfovibrio , which has been associated with bowel disease and inflammation, was noticeable. When the fecal flora from either the healthy or the sick twin was transplanted into groups of germ-free mice, the mice that received the kwashiorkor sample started to lose weight, like their human counterpart.

  • Giving these mice a peanut-based ready-to-use therapeutic food led to a brief rise in weight and a return of their microbiota toward normal.

    “when the mice are fed a peanut-based, ‘ready-to-use’ therapeutic food, their weight transiently increases and their microbiota normalize115.”
  • When germ-free mice carrying a kwashiorkor-associated microbiota ate a standard Malawian diet of tomatoes and corn, they lost weight.

    “germ-free mice that have been colonized with a ‘kwashiorkor’ microbiota experience weight loss when they are fed a typical Malawian diet, which is based on tomatoes and corn.”
  • The gut microbiotas of twin pairs differing in kwashiorkor status are different.

    “Twins that are discordant for kwashiorkor have distinct microbiotas”
  • Several diet-induced host phenotypes are sufficiently mediated by changes in the gut microbiota.

    “For example, several diet-induced host phenotypes are sufficiently mediated by changes in the gut microbiota (85–88).”
  • The gut microbiota and microbiome help extract and metabolize dietary ingredients.

    “The microbiota/microbiome in turn plays an important role in extracting and metabolizing dietary ingredients9-14.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
