Abstract People with spinal cord injury (SCI) are predisposed to pressure ulcers (PU). PU remain a significant burden in cost of care and quality of life despite improved mechanistic understanding and advanced interventions. An agent-based model (ABM) of ischemia/reperfusion-induced swelling and PU (the PUABM) was created, calibrated to serial images of post-SCI PU, and used to investigate potential treatments tests of anti-inflammatory treatments such as corticosteroids and a neutralizing antibody targeted at Damage-Associated Molecular Pattern molecules (DAMPs) suggested that, at best, early software at a sufficiently high dose could attenuate local swelling and reduce pressure-associated tissue damage, but could not reduce PU incidence. The PUABM therefore shows promise as an adjunct for mechanistic understanding, diagnosis, and design of therapies in the establishing of PU. Author Summary A virtual GLPG2451 pressure ulcer was created as a platform to test therapies and determine the mechanisms most correlated with unfavorable results. A coating of tissue fed with oxygen and diffusible molecules via blood vessels could develop an ulcer if pressure was applied, by simulating constriction of blood vessels in a circular region. Simulated ulcers were visually much like GLPG2451 digital photographs of ulcers in individuals with spinal cord injury in their irregular shapes, jagged edges, and overall progression in time. Statistical analyses of simulation outputs exposed that swelling was an important determinant of ulcer severity and overall tissue damage. However, simulated medical trials exposed that obstructing the negative effects of swelling could not prevent ulceration, and in order to be beneficial whatsoever for this specific type of ulcer, anti-inflammatory treatments must be applied during the earliest phases of ulcer formationbefore many medical indications of ulceration appear. Intro Pressure ulcers (PU) impact 2.5 million US acute care patients and cost up to $1 billion per year . They are a significant source of morbidity in both hospitalized individuals and community-dwelling individuals with impaired mobility. PUs are especially common in individuals.
