Chronic cutaneous wounds are a major burden on patients, healthcare providers, and the US healthcare system. This study, carried out in part by the Wound Healing Society's Government Regulatory Committee, aimed to evaluate the current state of National Institutes of Health funding of cutaneous wound healing-related research projects. National Institutes of Health Research Portfolio Online Reporting Tools Expenditures & Results system was used to identify wound healing projects funded by the National Institutes of Health in the 2012 fiscal year. ⋯ New applications and pre-existing applications accounted for 39.6 and 55.0% of the awarded grants, respectively. Grants awarded to investigators affiliated with universities accounted for 68.1% of grants and 25.3% were to investigators in the private sector. This analysis of current National Institutes of Health funding may facilitate more transparency of National Institutes of Health-allocated research funds and serve as an impetus to procure additional support for the field of wound healing.

Burn wound progression is caused by many mechanisms including local tissue hypoperfusion, prolonged inflammation, free radical damage, apoptosis, and necrosis in burn wounds. Autophagy, a homeostatic process by which cells break down their own components, was found to protect against ischemic injury, inflammatory diseases, and apoptosis in some cases. We tested whether rapamycin, an autophagy inducer, could ameliorate burn wound progression and promote wound healing through autophagy enhancement. ⋯ The apoptotic rates in treated wounds were much lower than controls as determined by terminal deoxynucleotidyl transferase mediated nick end labeling assay. Finally, histomorphological analysis showed that burn wound progression in the treatment group was ameliorated. The time to wound reepithelialization was shorter in the treated wounds than controls 22.5 ± 1.4 days vs. 24.8 ± 1.3 days (mean ± standard deviation, p < 0.01).

Approximately 40% of burn patients develop scar contractures. It is unknown which scar contracture therapy best optimizes activities of daily living (ADL). The appropriateness of self-reported outcome tools in measuring anti-scar contracture therapies has not been assessed. ⋯ There is insufficient data on the dimensionality and responsiveness of existing scales to support their use for measuring ADL in burn patients. Existing scales do not comprehensively measure ADLs as an isolated parameter. A psychometrically valid, comprehensive self-reported burn contracture scale that measures ADLs among a diverse group of burn patients needs to be developed to optimize burn contracture treatments and develop new therapies.
