概括

伤口关闭后的高透皮水损失 (TEWL) 预测慢性伤口的复发. 测量TEWL治疗后可以通过识别患有重伤风险的患者来改善伤口管理.

科学领域:

皮肤病学皮肤病学
伤口治愈研究研究伤口治愈研究
生物标志物发现发现

背景情况:

慢性伤口是一个重大的临床挑战,高复发率会影响患者的生活质量.
目前的伤口关闭终点侧重于重新上皮化,可能会忽视关键的皮肤屏障功能恢复.

研究的目的:

评估皮肤间流失的水分 (TEWL) 作为慢性伤口关闭后复发的预测因素.
调查TEWL测量是否可以作为创伤愈合成功的可靠生物标志物.

主要方法:

一项前性观察试点研究,涉及72名患有慢性伤口 (例如压力,糖尿病) 的患者.
在关闭的伤口部位和相反的健康皮肤上进行了非侵入性的TEWL测量.
关闭后 (V0) 每两周记录一次测量,最多5次访问或直到复发,用后勤回归和千平方测试进行分析.

主要成果:

在12周内观察到39%的复发率.
在关闭后较高的TEWL得分和增加伤口复发的几率之间发现了显著的关联 (单变量OR:1.26,多变量OR:1.34).
一个TEWL切线值为24.1g·m−2·h−1预测了高准确度的复发 (AUC=0.967).

结论:

关闭后的TEWL是各种伤口类型中慢性伤口复发的重要和普遍预测因素.
这些发现表明,TEWL是可靠的伤口复发生物标志物,可能需要将其纳入作为关闭伤口的临床终点.
恢复皮肤屏障功能,以正常化的TEWL表示,可能是成功伤口愈合的关键,但目前被忽视的标准.

Inflammatory Response II: Inflammatory Exudate and Tissue Repair

Inflammatory Response II: Inflammatory Exudate and Tissue Repair

The immune system's inflammatory response destroys the invading pathogen, permitting the tissue to heal. The changes during the cellular and vascular stages allow exudate formation at the site of inflammation. The inflammatory exudate released from the wound has high protein content and a specific gravity above 1.020.
The typical wound exudate is odorless, transparent, straw-colored, thin, and watery. Exudate, however, can differ depending on the state of wound healing. Likewise, the...

Phases of Wound Repair

Phases of Wound Repair

Following injury, the integrity of the injured tissues must be reestablished. For example, in skin tissue, wound repair involves coordination among resident skin cells, blood mononuclear cells, extracellular matrix, growth factors, and cytokines to complete the healing cascade.
Formation of Blood Clot
In case of deep injuries, trauma to blood vessels results in blood loss. In the meantime, phospholipids released from the ruptured endothelial cellular membrane are converted into arachidonic...

Clinical Applications of Epidermal Stem Cells

Clinical Applications of Epidermal Stem Cells

Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own...
