概括
准确的皮肤颜色表征对于各种研究队伍至关重要. 目前的方法,包括主观的尺度和种族类别,不能充分反映更深的皮肤色调,可能会扭曲医疗器械开发的结果.
科学领域:
- 生物医学工程 生物医学工程
- 医疗器械开发 医疗器械开发
- 健康 公平 卫生 公平
背景情况:
- 脉冲氧计表现差异存在于肤色较深的人群中.
- 研究队伍中不充分的多样性,特别是关于皮肤色素的多样性,有助于这些绩效差距.
- 需要标准化和公平的方法来表征皮肤色素,以确保具有代表性的研究.
研究的目的:
- 评估常见皮肤色素测量方法的可靠性和可比性.
- 为了比较不同解剖部位的皮肤色素表征发现.
- 证明种族类别 (例如,美国国家卫生研究院 (NIH)) 不能准确预测皮肤颜色.
主要方法:
- 采用了三个主观方法:感知Fitzpatrick (pFP),蒙克皮肤色 (MST) 和Von Luschan (VL).
- 使用了两个客观方法:Konica Minolta CM-700d光谱相仪和Delfin皮肤颜色捕捉 (DSCC) 色素计用于个别类型角度 (ITA).
- 在789名成年参与者中评估了多个测量点,计算了操作员可感知性和方法可重现性的 ΔE.
主要成果:
- 蒙克皮肤色调 (MST) 尺度表现出最广泛的亮度范围; ·卢尚 (VL) 的相邻类别是最难辨别的.
- 使用ITA<-30°来定义"黑色"皮肤,14%的参与者被归类为黑色皮肤,而pFP为26%,MST为16%.
- 使用"黑人或非裔美国人"自我识别"黑色"皮肤导致23%的分类,而ITA<-50°分类仅为7%.
结论:
- 常见的皮肤颜色表征方法,包括主观尺度和种族,具有显著的局限性.
- 对同一队列应用的不同方法产生了不同的结果,有些人高估了多样性.
- 目前用于定义"黑色"皮肤的ITA值不够敏感,导致代表性不足.

Pigmentation
2.3K
The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...

Skin Cancer

Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...
