PEM Flashcards
PEM
most outstanding?
energy deficiency
Marasmus
severe wasting
slower onset / better adapt
Kwashiorkor
Edematous PEM
Generally w/o wasting
Protein deficiency (+ metabolic stress + MN deficiency/imbalance)
Rapid onset “mal-adaption”
pure caloric deficiency
starvation
cachexia
associated with inflammatory or neoplasm
not reversed by feeding alone
sarcopenia
subnormal amount of skeletal muslce w/o weight loss
% Global Underweight Stunted Wasted Malnutrition related deaths

Who is more at risk for marasmus and who is more at risk for kwashiorkor
marasmus - 0-12 mos
Kwash - 12-24 mos
Underweight =
> 2SD below median (50%)
<3rd% for age
Stunting =
Length for age
<2 Z score
< 3 Z score severe
Wasting
Weight relative to length % IBW 80-89 mild 75-79 moderate <75 severe
OR
BMI <18
severe <16
Fuel utilization during starvation - shifts?
glucose down
Ketones up
FA up
Marasmus response to starvation
decrease BMR - hypotention/hypothermia/bradycardia
Normal response to starvation - muscle - brain - liver - kidney
muscle - increased utilization of TGs/FAs - decreased protein degradation
brain - increased ketones
liver - gluconeogenesis
kidney - decreased urea production (by liver) and excretion
Normal response to starvation
endocrine
decreased insulin and thyroid
increased Epi and cortisol
