- 重新定义新生儿VA充足度和不足度的门.
- 评估母亲VA状态对新生儿VA状态的预测价值.
主要方法:
- 在中国重庆1901年对母亲和新生儿进行的截面研究.
- 评估VA营养状况通过血清VA水平和饮食VA摄入量 (到出生第三个三个月).
- 对新生儿血清VA水平与母亲VA水平以及已确定的成人VA值的分析.
主要成果:
- 根据饮食摄入量和血清水平,母亲和新生儿的VAD率分别为27.09%和23.36%.
- 88.8%的新生儿的血清VA水平低于成人VAD值 (<0.70μmol/L),但所有人都在临床上健康.
- 新生儿VA水平与母亲VA水平呈正相关性,新生儿与母亲VA营养充足时,估计适度值为≥0.489μmol/L.
结论:

01:30Vitamins
2.7K
Vitamins, derived from the Latin word for life, are essential organic substances required in small quantities for optimal growth and overall well-being. Unlike other organic nutrients, vitamins don't act as sources of energy or building materials but rather facilitate these nutrients' utilization by the body. Vitamins are predominantly coenzymes, assisting enzymes in specific chemical actions, like the oxidation of glucose for energy involving B vitamins. Most vitamins are not produced...

2.0K
Parenteral Nutrition (PN) delivers essential nutrients directly into the bloodstream, bypassing the digestive system. It is commonly used for individuals with severe digestive disorders or conditions that prevent normal nutrient absorption.
PN can be administered through two primary routes:
1. Central Parenteral Nutrition (CPN):
CPN involves delivering a high concentration of nutrients through a large vein. This is typically achieved using a Peripherally Inserted Central Catheter (PICC) or,...

975
Understanding the physiological differences in the pediatric population is crucial for effective pharmacotherapy. Neonates, infants, and children exhibit significant variations in gastric pH, gastric emptying time, intestinal transit time, and biliary function. These variations profoundly affect oral drug absorption, necessitating a nuanced approach to pediatric dosing.Neonates present with a unique physiological profile, having a gastric pH greater than 4 and faster and more irregular gastric...

01:28Development of the Oral Microbiota
73
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,...
