概括

现在在美国推对新生儿进行克拉贝病 (KD) 查. 通过新生儿查进行早期检测,可以及时进行造血干细胞移植 (HSCT),改善婴儿KD的存活率.

科学领域:

遗传学和罕见疾病.
溶酶体储存障碍溶酶体储存障碍
新生儿查新生儿查

背景情况:

克拉贝病 (KD) 是一种罕见的,致命的自体逆性溶酶体疾病,由GALC基因变异引起,导致精神病积累和神经退行.
婴儿KD (IKD) 呈现于12个月,如果不治疗,会出现严重的症状和早期儿童死亡.
造血干细胞移植 (HSCT) 可以改善IKD的存活率,但最有效的是在早期进行时,在症状出现之前.

研究的目的:

强调新生儿对克拉贝病 (KD) 的查的重要性.
讨论GALC活动和心理水平在KD诊断中的作用.
强调需要为经历KD早期诊断和治疗决策的家庭提供支持系统.

主要方法:

针对KD的新生儿查使用了干血斑点中的低银糖胺酶 (GALC) 水平.
二级测试高精神病度提高了婴儿KD (IKD) 的查特异性.
最近,IKD被列入美国卫生和人类服务部长推的统一查小组.

主要成果:

新生儿查可以更早地诊断IKD,可能是在临床症状出现之前.
早期诊断有助于及时进行血造干细胞移植 (HSCT) 的干预.
查晚期KD表型的有效性仍然不确定.

结论:

实施强大的IKD新生儿查系统对于最大限度地提高治疗效益至关重要.
支持家庭快速做出关于HSCT的决定是必不可少的.
确保在诊断后迅速获得HSCT对于改善婴儿克拉贝病的结果至关重要.

Development of Human Microbiota

Development of Human Microbiota

The human microbiota begins developing at birth and undergoes continual change as we age. Infancy marks a critical period of microbial sensitivity, offering a “window of opportunity” during which beneficial microbes help mature the immune system. By age three, children typically develop a more stable and diverse microbial community. Newborns acquire microbes from their immediate environment; vaginal delivery favors maternal vaginal microbes, while cesarean births favor microbes from the skin...

Development of the Oral Microbiota

Development of the Oral Microbiota

The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...
