队列研究 

Study design:

Cohort study 

研究目的:

(1)建立极/超早产儿甲状腺激素的正常参考值。 收集< 32 周的正常呼吸或湿肺的早产儿,描绘其生长曲线,并随访其神经发育情况,取生长曲线与同性别同胎龄标准生长曲线相平行,且神经发育正常的那部分早产儿,建立甲状腺功能的正常参考值。 (2) 评价甲状腺激素与 EUGR 和 BPD 及其严重程度的关系。 建立极/超早产儿队列,评价THOP 与 EUGR 和 BPD 及其严重程度的关系。  

Objectives of Study:

(1) To establish the normal reference value of thyroid hormone in extremely/very preterm infants. Data from preterm infants < 32 weeks with normal breathing or wet lungs were collected, describing their growth curves, and following up their neurodevelopment. Data from preterm infants whose neurodevelopment was normal and whose growth curves were parallel to the standard growth curves for the same sex and gestational age were collected to establish the normal reference value of thyroid function for preterm infants. (2) To evaluate the relationship between thyroid hormone and EUGR, BPD, and BPD's severity. Establishing an extremely/very preterm infant cohort to assess the relationship between THOP and EUGR, BPD, and BPD's severity.

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC:

数据采集:本次临床试验数据收集均按照注册时的方案执行。根据临床研究伦理委员会的国际和中国规范,所有数据收集需要征得监护人的同意,并受该伦理委员会的监督。纳入新生儿的实际监护人将被口头告知本次研究的实际情况,并签署知情同意书。在后续的数据收集中,数据收集人确保只收集那些同意参与本次研究的新生儿的资料。 数据管理:1)研究开始前:制定科学完善的研究方案,制定 SOP,合格研究者选择,参与人员的培训。2)研究进行中:有序规范的开展,定期内部自查和外部监督管理,各个协作者间有效沟通。 研究结束后:正确的数据分析,恰当的结果解读。得到的数据需要安全匿名保存。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

Data collection: The data collection of this clinical trial was carried out in accordance with the registration protocol. According to the international and Chinese norms of the Clinical Research Ethics Committee, all data collection requires the consent of the guardian and is supervised by the Ethics Committee. The actual guardian of the included newborn will be orally informed of the actual situation of this study and will sign an informed consent form. In subsequent data collection, the data collector ensured that data were collected only from newborns who had consented to participate in the study. Data management: 1) Before the start of the study: formulate a scientific and perfect research plan, develop SOP, select qualified researchers, and train participants. 2) The research is in progress: orderly and standardized development, regular internal self-examination and external supervision and management, and effective communication among various collaborators. After the study: Proper data analysis, and proper interpretation of the results. The resulting data needs to be kept securely and anonymously.
