概括
与健康同龄人相比,患有状细胞疾病 (SCD) 的儿童表现出身体组成的改变,体重和身高较低,但总体质较高. 早期干预对于治疗儿科SCD患者生长衰竭至关重要.
科学领域:
- 儿科血液学 儿科血液学
- 身体组成分析 身体成分分析
- 状细胞疾病研究研究
背景情况:
- 发育不良是儿科状细胞病 (SCD) 的常见并发症.
- 在SCD患者中,可能会发生改变组织区的生长和发展.
研究的目的:
- 为了分析埃及儿科SCD患者的身体组成.
- 使用双能X射线吸收计 (DEXA) 进行全面的,非侵入性的评估.
主要方法:
- 招募了40名患有SCD的儿童 (≤18岁) 和40名年龄/性别匹配的健康对照.
- 从患者记录中收集人口统计,临床和实验室数据.
- 使用MedixDR-全身DEXA系统评估身体组成.
主要成果:
- SCD患者的体重和身高Z分数显著降低 (p < .001).
- 在SCD患者中,总体肌肉质量显著增加 (p = .006).
- 总体脂肪百分比较低,但没有统计学意义 (p = .09). 骨矿物质密度,基础代谢率和脂肪组织分布是可比的.
结论:

01:07Scanning Electron Microscopy
5.1K
A scanning electron microscope (SEM) is used to study the surface features of a sample by using an electron beam that scans the sample surface in a two-dimensional manner. Typically, areas between ~1 centimeter to 5 micrometers in width can be imaged. SEM can be used to image bacteria, viruses, tissues as well as larger samples like insects. Conventional SEM gives a magnification ranging from 20X to 30,000X and spatial resolution of 50 to 100 nanometers.
