Application of magnetic resonance imaging-compatible incubator in cranial magnetic resonance imaging for neonates: a multicenter prospective randomized clinical trial / 中国当代儿科杂志

OBJECTIVE@#To study the safety and efficacy of magnetic resonance imaging (MRI)-compatible incubator in cranial MRI examination for neonates.@*METHODS@#A total of 120 neonates who were hospitalized in three hospitals and needed to undergo MRI examination were randomly divided into a control group and an experimental group, with 60 neonates in each group. The neonates in the experimental group were transferred with MRI-compatible incubator and underwent cranial MRI examination inside the MRI-compatible incubator, and those in the control group were transferred using a conventional neonatal transfer incubator and then underwent MRI examination outside the incubator. The two groups were compared in terms of the primary efficacy index (total examination time), secondary efficacy indices (times of examination, MRI completion rate on the first day of use), and safety indices (incidence rate of adverse events and vital signs).@*RESULTS@#There were no significant differences in total examination time, times of examination, and MRI completion rate on the first day of use between the two groups (@*CONCLUSIONS@#The use of MRI-compatible incubator does not significantly shorten the examination time of cranial MRI, but it does provide a relatively stable environment for examination with acceptable safety. There is a need for further studies with a larger population.

Early diagnostic value of the test of infant motor performance for preterm infants' abnormal motor development:A literature review / 中国实用儿科杂志

OBJECTIVE: To investigate the application of NBNA and TIMP in the follow-up of preterm infants,and to as⁃sess the value of them in early diagnosis of abnormal motor development of preterms. METHODS: Databases including Pubmed,Embase and Cochrane Library,China National knowledge internet,and Wanfang data were searched for studies about neuro-behavior or motor assessments with NBNA or TIMP. The methodological quality of the included studies was assessed with COSMIN checklist,then the predictive validity of NBNA and TIMP were compared. RESULTS: Ultimately,16 studies were included,5 of which were about the application of NBNA in follow-up of preterm infants. But many fac⁃tors might pose threat to methodological quality. As for TIMP,11 studies were included,9 of which showed that with a satisfying predictive validity(sensitivity:0.50 to 1.00;specificity:0.68 to 1.00)or moderate correlation(r:0.36 to 0.44)for the neurodevelopmental scores after half a year old. TIMP is helpful in making early diagnosis for neurodevelopmental disability. CONCLUSION: With satisfying predictive validity for long-term neurological development outcomes of the pre⁃term infants,TIMP is considered as an alternative method of assessing functional movements in preterms.
