If a burn wound induces sustained systemic inflammation and subsequent hypermetabolism, which physiological consequence becomes a limiting factor in successful wound closure?

💡 Explanation

Systemic inflammation and hypermetabolism from a severe burn injury dramatically increase the body's demand for amino acids to support immune function and gluconeogenesis; therefore, depletion of circulating amino acid pools impairs collagen synthesis and wound repair, rather than accelerating keratinocyte differentiation because it cannot be sustained.

• Why does epidermal growth factor (EGF) promote keratinocyte proliferation during wound healing, rather than immediate collagen deposition?
• If a patient has a dysfunctional factor VIII, which consequence follows regarding blood coagulation?
• Why does carbohydrate fermentation increase in the large intestine when dietary fiber intake suddenly increases?
• If a patient exhibits severe muscle weakness and neurological dysfunction despite adequate protein intake, which cofactor-related deficiency is the MOST likely underlying cause?
• Why does aplastic anemia increase susceptibility to opportunistic infections more than iron deficiency anemia?
• If a viral infection triggers excessive production of IL-1β cytokine in lung tissue, which consequence follows regarding inflammation resolution?
