ABSTRACT
Objective:To explore the influence of different mental status (evaluated by Likert scale) on the first success rate, image artifacts and examination time of cone beam CT (CBCT) in infants and young children.Methods:Prospective analysis of children aged 1-6 years (98 cases) who underwent CBCT examination, before the examination, the children were scored in seven aspects: activity, adaptability, attention, mood, gender, age and parents′ attitude, and the total score was calculated, The total score was used as the test variable, and the success rate of the first examination, the artifact of the image and whether the examination time was longer than 2 minutes were used as the state variable. Using SPSS 16.0 to draw the ROC curve, the area under curve (AUC), significance, maximum Yoden′s index and their corresponding diagnostic (evaluation) critical values were obtained.Results:The success rate of the first examination was 78.6%(77/98), the AUC was 0.949 ± 0.025, the significance P < 0.05, the maximum Yoden′s index was 0.766, the corresponding critical value of diagnosis (evaluation) was 15; the artifact-free rate was 67.3%(66/98), the AUC was 0.873±0.038, the significance P < 0.05, the maximum Yoden′s index was 0.549, and the corresponding critical value of diagnosis (evaluation) was 15; the proportion of examination time in 2 minutes was 80.6%(79/98), the AUC was 0.854 ± 0.039, the significant P < 0.05, the maximum Yoden′s index was 0.614, and the corresponding critical value of diagnosis (evaluation) was 14. Conclusions:The Likert scale scoring method based on Thomas′s temperament analysis theory has certain application value in the psychological evaluation of children before cone-beam CT examination. For children whose total score is greater than or equal to 14, sedation or psychological counseling should be carried out before examination in order to effectively improve the success rate of examination and reduce the occurrence rate of artifacts in images, further more to reduce radiation dosage and increase the examination circulation of CBCT in children.
ABSTRACT
Objective@#To discuss the success rate and image quality in pediatric patients who used chloral hydrate before their cone beam computed tomography exam.@*Methods@#1752 patients aged 1 to 6 were selected for this retrospective study. They were divided into sedated group (219 cases) and non-sedated group (1 533 cases). The success rate and image quality were compared between two groups.@*Results@#The sedated group had a higher success rate to non-sedated group: 99.5%(218/219) vs. 90.4% (1 386/1 533). The motion artifact in sedated group was lower than non- sedated group with I degree: 4.8% (15/314) vs. 20.1%(327/1 630) and II degree: 0.3%(1/314) vs. 12.2%(199/1 630).@*Conclusion@#Giving chloral hydrate to pediatric patients before their CBCT exam would improve both success rate and image quality, and reduce unnecessary radiation expose.

ABSTRACT
PURPOSE: This study aimed to evaluate the effect of delayed lactogenesis II on early milk volume in mothers expressing milk for their preterm infants. METHODS: 142 mothers with preterm infants participated in a longitudinal cohort study, the milk volumes over 14 days postpartum between mothers with delayed lactogenesis II (≥ 72 hours) and mothers with non-delayed lactogenesis II(< 72 hours) were compared using Wilcoxon's rank sum tests. RESULTS: The prevalence of delayed lactogenesis II among mothers of preterm infants was 36.0% (36/100). There existed negative correlations between the onset of lactogenesis II and the daily milk volumes(r(s) = −0.525~−0.354, p = .002 ~ p < .001). The milk volumes in every 24-hour of the 14 days postpartum in delayed group were significantly less than that in non-delayed group (p = .002 ~ p < .001). After controlling for the covariates, pregnancy-induced hypertension syndrome, delayed expression initiation, shorter daily sleeping time were found to be the risk factors for delayed lactogenesis II. CONCLUSION: Delayed lactogenesis II was associated with lower milk volume in early postpartum period. Women who were at risk for delayed lactogenesis II need targeted interventions and additional support during pregnancy and postpartum.

Objective To explore the milk production and its regularity in mothers with preterm infants hospitalized in NICU during periods of mother-infant separation,and to analyze the associating factors.Methods Totally 122 mothers with preterm infants hospitalized in NICU were recruited from February to December,2017.Continuous measurements of daily breast milk production were performed.The maternal lactation related comprehensive questionnaire and Edinburgh Postnatal Depression Scale (EPDS) were used.The Pearson correlation analysis and multiple linear regression analysis were conducted using the Statistical Analysis Systems (version 9.2).Results The milk volumes for the first 14 days postpartum showed a trend of rising among mothers.The mean milk volume on day 14 postpartum was (535.43±256.97) ml.The mean initiation time of lactogenesis stage Ⅱ was (68.23±26.42) h.The correlation coefficient of lactation between day 4 and day 14 was 0.707 0(P＜0.01).The multiple linear regression analysis revealed that the pregnancy induced hypertension syndrome,initiation time of lactogenesis stage Ⅱ,EPDS score,gestational age,maternal age were the influencing factors of milk volume for mothers during periods of mother-infant separation.Conclusion The milk volume of mothers with preterm infants was relatively lower compared with mothers with full-term infants during the early stage postpartum,and the onset of lactogenesis stage Ⅱ was later.In clinical nursing work,healthcare providers should pay special attention to mothers with older maternal age,smaller gestational age,pregnancy induced hypertension syndrome,higher EPDS score,and later initiation time of lactogenesis stage Ⅱ.
