TGF-β1 (transforming growth factor β1) was considered to play a critical role in the forming of hypertrophic scars. Smad, as a kind of signal downstream mediators, can modulate the functions of TGF-β1. Smad7 can regulate TGF-β1/Smad pathway and present negative feedbacks, which prevents fibrosis mediated by TGF-β1. ⋯ Enhanced degradation of Smad7 protein in the fibroblasts of hypertrophic scars was prevented by proteasome inhibitors MG132 / MG115. Furthermore, it was found that TGF-β1 stimulation increased Smad7 protein expression after silencing Smurf2 gene in hypertrophic scar fibroblasts, and enhanced Smad7 degradation was prevented in hypertrophic scar fibroblasts after Smurf2 was silenced. It was implied that ubiquitin degradation mediated by Smurf2 might contribute to decreased Smad7 protein levels following TGF-β1 stimulation in the fibroblasts of hypertrophic scars.

As compared to younger adults, older people have a greater risk of domestic accidents, such as burns, and their prognosis is worsened by a diminished physiological ability to face a thermal trauma. The in-hospital mortality is adversely affected by old age and burn size, whereas less is known about the long-term-survival in elderly patients who survive a burn injury. The aim of this study was to investigate if elderly burn patients after discharge from a Swedish National Burn Centre have a shorter remaining life compared to the national population, by using calculated remaining Life Expectancy (rLE). ⋯ We found that the long-time survival of elderly patients after burns is shorter than that of a national control, the magnitude of which is quantitatively important. The current study does not support that burn related factors account for this effect and the reason should therefore be sought in other factors, such as e.g., co-morbidity or psychosocial issues.

Nursing is an embodiment of knowledge, clinical work, and interpersonal communication. Effective nursing care has a distinct influence on the overall satisfaction and experience of the patient. Communication is said to be indispensable in the delivery of quality healthcare. Effective communication between nurses and patients has proven to yield better results with pain control and improved psychological status of patients. ⋯ Due to the subjective nature of pain, the current study highlights the need for increased communication for an effective assessment and management of pain among patients with burns. It is, therefore, imperative that nurses be well trained in communication with an emphasis on patient-centered communication.

In some cases, the tongue and oesophagus tissues are damaged by the corrosive burn. Surgical interventions may cause scar formation, and severe burns treatment methods are limited. This study aims to investigate bromelain, a phytotherapeutic product, on the corrosive burn as a non-surgical option and as an adjunctive therapy, insofar as the treatment of corrosive wounds is not limited only to the treatment of oxidative stress and inflammatory reactions. ⋯ Bromelain administration decreased oxidant and inflammatory parameters and increased antioxidant levels in NaOH-induced corrosive burns. Thus, we concluded that bromelain may protect the tongue and oesophagus tissues with its anti-inflammatory and antioxidant effects.
