This work is based on DFU patients, seeks to conduct a fully powered clinical study testing i) If DFU with a history of biofilm infection closes with deficient barrier function. ii) whether such functionally deficient wound closure, manifested as high TEWL, is associated with greater wound recurrence. The primary parent study will also address molecular mechanisms implicated in biofilm-induced loss of skin epithelial barrier integrity in DFU patients.
