Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The expectation is that successful intervention should keep the wound closed for at least 90 days. This study contends that visual inspection of wounds is insufficient to certify closure - a critical endpoint that drives treatment decisions. Considering that almost two-thirds of all chronic wounds are estimated to be biofilminfected6, and the observation that biofilm-infected wounds may be visually closed but functionally (barrier function) open, the significance of the proposed hypothesis is substantial.
The proposed study has the clear potential to lay a strong rationale that would potentially change the wound care paradigm by requiring that measurement of skin barrier function be the new endpoint to define wound closure. Reported recurrence rates for most chronic ulcer types remain extremely high, ranging from 40-79%4,5, 24%-57% for venous ulcers, and upward of 60% for diabetic ulcers supporting the importance of preventive efforts1,2. In that context it is of extraordinary significance to ask whether "defective closure" (visually closed with TEWL (Trans-Epidermal Water Loss) \>3x the value of intact skin; high TEWL) predicts poor post-closure outcome e.g. recurrence. These questions may only be meaningfully asked in a patient-based pilot and that is exactly the intent of Aim 2. Findings of the proposed pilot will inform a larger future trial.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
TEWL - Epiceram
Subjects will have the TEWL reading completed at the wound site and a control site (anatomically matched site on the patients contralateral side) at the second study visit. If the wound site reading is less than 3 times the value of the control site subjects
Epiceram Skin Barrier Function
Epiceram is a non-sterile, viscous, lipid-rich emulsion
TEWL - Vaseline Petroleum Jelly
Subjects will have the TEWL reading completed at the wound site and a control site (anatomically matched site on the patients contralateral side) at the second study visit. If the wound site reading is less than 3 times the value of the control site subjects
Vaseline Petroleum Jelly
A skin protectant used for temporarily protecting minor cuts, scraps, burns, and helps to protect and help relieve chapped or cracked skin and lips.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
2. Willing to comply with protocol instructions, including all study visits and study activities.
3. One of the following: Healed wound (within 10 days prior to consent/screening visit) that was previously a chronic wound of multiple etiologies and open for at least30 days, including:
i. Diabetic foot ulcers, Wagner grade 1-3 ii. Pressure ulcers, stage 2-3 iii. Venous leg ulcers, confirmed by venous duplex iv. Burn wounds
4. If candidate has a diabetic foot ulcer, ABI score measurement at Visit 1 must be between 0.7 and 1.2. If score is below or above, candidate will be considered a screen fail. Score can be gathered from EMR in previous 3 months to visit 1 if done as SOC or completed during visit 1.
Exclusion Criteria
2. Subjects with marked immunodeficiency (HIV/AIDS, organ transplant patients and cancer patients and patients with autoimmune disease on immunosuppressive medications).
3. Wounds closed or to be closed by flap or graft coverage - including stage 4pressure ulcers and Wagner grade 4 or 5 diabetic foot ulcers.
4. Prisoners
5. Patients with allergies to petrolatum
6. Patients who are currently enrolled in another research study which includes investigational treatment and/or medication
7. Patients with an HbA1c score greater than 10.0 at Visit 1, will be considered a screen fail. Score can be gathered from EMR in previous 12 months to visit 1 if done as SOC, or completed during visit 1.
