ABSTRACT
Objective:To study the outcomes and post-discharge follow-up of neonatal tracheotomy in neonatal intensive care unit(NICU).Methods:This study included patients who were admitted to NICU in Beijing Children′s Hospital from January, 2016 to August, 2021, and less than 28 days or 44 weeks(corrected age)on admission, and required tracheotomy.The patients were divided into tracheotomy group and the non-tracheotomy group (the parents signed to refuse the tracheotomy) according to whether perform tracheotomy.Demographic data, general hospitalization information, diagnosis, indications for tracheotomy, follow-up outcomes at 3/6/12 months of age after discharge of patients were collected and analyzed.Results:Totally 26 patients were included in this study, 14 cases in tracheotomy group and 12 cases in non-tracheotomy group.The average gestational age was(37.7±3.80)weeks and(38.99±1.83)weeks, and birth weight was(2 823.57±948.89)g and (3 320.83±378.76)g, respectively.There were no significant differences in sex, gestational age, birth weight, age on admission, weight on admission, age at diagnosis, ratio of endotracheal intubation for respiratory support on admission between two groups( P>0.05). The commonest indications of tracheotomy group were bilateral vocal cord paralysis(50.0%) and congenital anomaly/defect of throat/larynx(21.4%), and the commonest indications of non-tracheotomy group were bilateral vocal cord paralysis(50.0%) and vocal cord/subglottic mass(25.0%), and there was no significant difference between two groups( P>0.05). The rate of discharge-against-medical order of tracheotomy and non-tracheotomy group was 7.14% and 66.67%( P=0.003), respectively.The total follow-up rate of tracheotomy and non-tracheotomy group was 88.9% and 38.9%, while the follow-up rates at 3 months, 6 months, and 12 months were 100.0% vs. 50.0%, 83.3% vs. 41.7%, and 81.8% vs. 25.0%, respectively, whose differences were statistically significant(all P<0.05). In the 14 cases of tracheotomy group, 3 cases died, 4 cases successfully removed the tracheal cannula, 5 cases did not remove the tracheal cannula, and 2 cases were lost. Conclusion:Bilateral vocal cord paralysis is the commonest indication of neonatal tracheotomy.Parents′ compliance in the tracheotomy group is significantly higher than that in non-tracheotomy group.To give caring skill training for parents of neonates with tracheotomy before discharge is beneficial for improving the overall prognosis of children.
ABSTRACT
Accurate and applicable reference intervals can provide important information for disease diagnosis, efficacy evaluation, and health monitoring. Age-dependent trends exist for many clinical laboratory indicators, and the interpretation of such indicators should consider the effect of age carefully. However, age-specific reference intervals have certain limitations in clinical application. Continuous reference intervals can not only help accurate interpretation of laboratory test results, but also provide a baseline value for dynamic monitoring of their changing trends. Based on the researches on pediatric reference intervals from our team, this paper introduces different algorithms for establishing continuous reference intervals, and their applicable conditions and implementation steps. The aim of this paper is to provide methodological guidance for the establishment of continuous reference intervals, so as to improve the quality of laboratory reports and the accuracy of clinical diagnosis in China.
ABSTRACT
Objective:To analyze the public demands for information about congenital birth defects in “Baidu zhidao” based on word frequency retrieval.Methods:Based on discussion between obstetrics and gynecology experts and epidemiological experts, the key words related to congenital birth defects were determined and the search strategy was formulated. Python 2.7 was used for web crawler search. Questions related to congenital birth defects were obtained on the “Baidu zhidao” platform, and then the R 4.0.2 software was used to process the data, complete the semantic analysis of keywords and statistical analysis of word frequency, and draw word cloud graph and polar chart to describe the key results.Results:A total of 16668 non-repetitive questions were retrieved from “Baidu zhidao” platform, and the frequency of semantic words was 15 371. Among them, 35.02% were the names and symptoms of congenital birth defects. In addition, the frequency of congenital heart disease was the highest (26.09%). The results of subject analysis of key words of birth defects showed that the average word frequency of diagnosis and treatment semantic words (49.55) was significantly higher than that of etiology and prevention semantic words (12.47). In addition, the key words of examination, cause, treatment, development and heredity were more frequently used in the semantic words related to the seven types of systemic malformations.Conclusion:The public in China has a high demand for information on congenital birth defect related diseases, and their causes, prevention and treatment, especially congenital heart disease.
ABSTRACT
Objective: To evaluate the applications and problems of statistical methods for articles published in《Chinese Circulation Journal》. Methods: We reviewed the statistical methods for original articles published in《Chinese Circulation Journal》in 2010, 2011 and 2015; general status with problems was analyzed and the situations were compared among different years. Results: A total of 404 articles were enrolled, statistical hypothesis testing was performed in 366 of them, 32 had descriptive statistics only and 6 articles were meta-analysis. The most frequently used statistical methods were student'st-test (57.4%), followed by chi-squared analysis (56.7%), analysis of variance (35.2%) and regression analysis (23.0%). The main statistical problems in Methods included in described method un-matched to really used method and insufifcient or wrong description. The proportion of insufifcient or wrong description in 2010 and 2011 was 36.6% (71/194), while in 2015 was 26.2% (55/210),P=0.02. The major wrong application of statistical approach was ignoring design with improper method and using unsatisifed precondition for speciifc analysis. The proportion of improper statistical method application in 2010 and 2011 was 19.1% (33/173), in 2015 was 19.7% (38/193),P=0.88. Conclusion: The quality of statistics was improved in 2015 than 2010 and 2011 for articles published in《Chinese Circulation Journal》; while there were still problems at certain degree, enhanced statistical review should be conducted in medical journals.
ABSTRACT
The pediatric reference intervals in clinical laboratory play an important role in diagnosis of illness,therapeutic monitoring,prediction of prognosis and health evaluation.Compared with establishing reference interval for adults,there are more challenges to establish pediatric reference intervals.Therefore,the procedure and key technologies of direct method and indirect method are stated based on the characteristics of children population and pediatric,by which to define,transfer and validate pediatric reference intervals.This study will provide systematically methodological ideas for clinical laboratories to establish pediatric reference intervals.
