ABSTRACT
Objective:To test the reliability and validity of the Chinese version of cyberbullying inventory for college students(CICS-CV)in the context of Chinese culture and make preliminary application.Methods:A total of 1 528 college students completed the CICS-CV, and 208 students completed CICS-CV after six months.Trait anger subscale of state-trait anger expression inventory-2, and Buss-Perry aggressive qusetionnaire were used as the criterion of cyberbullying aggression, and depression anxiety stress scales were used as the criterion for cyberbullying victimization to test its validity. Item analysis, exploratory factor analysis, reliability test, calibration validity test and corss-lag analysis were conducted by SPSS 24.0 software, and confirmatory factor analysis was conducted by Mplus 8.3.Results:The results of exploratory factor analysis showed that two factors were obtained named as cyberbullying aggression and cyberbullying victimization, and the factor loadings were 0.59-0.82, 0.59-0.80.Confirmatory factor analysis showed that the fitting index of the double factor model was fitting well ( χ2/ df=2.61, CFI=0.90, TLI=0.89, RMSEA=0.04, SRMR=0.05). The internal consistency coefficient of the two subscales were 0.88, 0.89, and test-retest reliability were both 0.97. There was a significant positive correlation between cyberbullying aggression(victimization) and the criterions( r=0.23-0.42, all P<0.05). Cross-lag analysis of moral disengagement and cyberbullying aggression showed that the first measurement of moral disengagement significantly predicted the second measurement of cyberbullying aggression( β=0.16, t=2.16, P<0.05). Conclusion:The CICS-CV has good reliability and validity, which can be used as an effective tool for evaluating college students' cyberbullying in China.
ABSTRACT
Objective:To analyze the early postoperative mortality and long-term reoperation of ASO and to explore the surgical risk and the reasons of long-term reoperation.Methods:The clinical data and follow-up data of ASO children undergoing surgery in Shanghai Children Medical Center from January 2010 to December 2020 were analyzed retrospectively. Four groups were divided into transposition of the great vessels(TGA/IVS) , transposition of the great vessels with ventricular septal defect(TGA/VSD) , Taussig-bing anomaly(TBA) , and two stage ASO(Ⅱ-ASO) groups. χ2 test was used to analyze the early mortality and long-term reoperation rates of ASO in different groups. Results:A total of 861 ASO patients were included in this study and 108 died early(12.5%, 108/861) . Seven hundred and fifty three cases were followed up and 102 cases were lost(13.5%, 102/753) . The median follow-up time was 7.23 years and the quartile interval was 4.74-9.37 years old. Sixty six patients(10.1%, 66/651) underwent long-term reoperation. Four patients(6%, 4/66) died after reoperation. In 241 cases of TGA/IVS, 24 cases(10%) were performed reoperation. In 256 cases of TGA/VSD, 23 cases(9%) had reoperation. In 126 cases of TBA, 18 cases(14.3%) for reoperation. And in 28 cases of Ⅱ-ASO only 1 case(3.6%) had reoperation. Among all the reoperation cases, there were 36 cases(2 deaths) for pulmonary angioplasty, 2 cases for pulmonary stenting, 10 cases for right ventricular outflow tract obstruction(RVOTO) repair, 2 cases for aortic valvularplasty, 5 cases for aortic valve replacement(2 deaths), 4 cases for aortic anastomotic stenosis repair, 3 cases for left ventricular outflow tract obstruction(LVOTO) repair, 2 cases for VSD residual shunt repair and 2 cases for coarctation of the aorta(CoA) correction.Conclusion:The early mortality rate of ASO surgery is still higher than that of developed countries. Long-term follow-up after ASO surgery should focus on right ventricular outflow tract stenosis and aortic valve insufficiency.
ABSTRACT
Objective:To study the changes of stenotic segment trachea diameter, trachea length and carina angle before and after slide tracheoplasty.Methods:From January 2010 to January 2018, 77 children with congenital tracheal stenosis(female=36) with complete clinical data accepted slide tracheoplasty in Shanghai Children's Medical Center were selected as the observation group. The diameter of stenosis segment, the length of stenosis segment, the full length of trachea and carina angle were measured by CT image, and the ratio of stenosis segment length to full trachea length was calculated. A group of children with normal trachea morphology and the same sample number, and they had no significant difference in age, height and weight were selected as the control group.Results:The median operative age of 77 children in the observation group was 1.3(1.1, 1.9)years old, the height was 76.0(72.0, 83.0)cm, and the weight was 9.0(7.9, 10.8)kg. The age, height and weight of 77 children in the control group were 1.5(1.0, 2.0) years old and 78.0(71.0, 85.0) cm, 9.2(7.9, 11.0) kg respectively. After slide tracheoplasty, the diameter of trachea in the stenotic segment of children increased from 2.7 mm to 4.4 mm, which was increased by 63.0%( P<0.001), but still smaller than that of children in the control group(6.1 mm). The average length of trachea was shortened by 0.7 cm( P<0.001), and there was no significant difference between the total length of trachea(5.4 cm) and the total length of trachea(5.5 cm). The postoperative carina angle decreased by 27.9°( P<0.001), there was no significant difference in postoperative carina angle between the observation group(93.0°) and the control group(90.7°). Conclusion:The diameter of reconstructed trachea in children with CTS is significantly increased, the length and carina angle of trachea become smaller after slide tracheoplasty. The morphology of trachea is more similar to children in the control group.
ABSTRACT
Objective:To summarize the morphological characteristics and clinical experience of pulmonary artery sling(PAS) combined with anomalous bronchial branching, and provide new considerations for surgically treating PAS.Methods:A retrospective review of surgical experience of all patients with anomalous bronchial branching from January 2012 to December 2018 at Shanghai Children's Medical Center was conducted. There are 4 types according to the morphology of anomalous bronchial branching: tracheal bronchus, bronchial trifurcation, bridging bronchus, tracheal bronchus combined with bronchial trifurcation. The proportion of patients with anomalous bronchial branching combined with PAS was counted. The rate of tracheoplasty for four types was determined. We measured the interbronchial and subcarinal/subpseudocarinal angles before and after tracheoplasty.Results:140 patients were included in our study. The tracheal diameter of 11(21%, 11/53) patients with tracheal bronchus and 4(9%, 4/44) patients with bronchial trifurcation was normal. Among these patients, 125 patients had congenital tracheal stenosis(CTS). 115 patients underwent tracheoplasty. The rate of tracheoplasty of bridging bronchus was higher than tracheal bronchus(100% vs. 60%, P=0.000). One-stage surgery was performed in 76(61%) patients who had PAS. The interbronchial and subcarinal/subpseudocarinal angles were significantly reduced postoperatively( P=0.000). Conclusion:It is difficult to explain merely with vascular compression in patients with PAS with CTS and anomalous bronchial branching. One-stage slide tracheoplasty is currently the optimal option.
ABSTRACT
Objective:Explore a predictive model for predicting postoperative hospital mortality in children with congenital heart disease.Methods:We retrospectively analyzed the characteristics of all children with congenital heart disease from January 1, 2006 to December 31, 2017 at Shanghai Children's Medical Center. Each procedure was assigned a complexity score based on Aristotle Score. In-hospital death prediction models including a procedure complexity score and patient-level risk factors were constructed using logistic regression analysis and machine learning methods. The predictive values of the models were tested by C-index. Results:A total of 24 693 patients underwent CHD operations were include in the study, there were 585 (2.4%) in-hospital deaths. In-hospital mortality for each procedure varies between 0 to 77.8%, with 32 procedures with 0 death record. The prediction model constructed using logistic regression found that in addition to the complexity score, other risk factors included age, height, operation history, echocardiography characteristics as well as certain laboratory test results (mainly coagulation factors) were significantly correlated with in-hospital death. Receiver operating curve analysis showed that prediction with only the complexity score resulted in an AUC of 0.654 (95% CI: 0.628-0, 681, P<0.01) while model containing patient-level risk factors had significant higher prediction value with AUC of 0.886 (95% CI: 0.868-0.904, P<0.01). Training with machine learning method resulted in a final prediction model with high prediction value ( AUC 0.889, with a sensitivity value for death prediction of 0.817). The key risk factors in machine learning model are in general agree with the logistic regression model however with subtle differences. Conclusion:Through combination of procedure complexity score with pre-operative patient-level factors, predictive model constructed using regression or machine learning method had high accuracy in in-hospital mortality prediction.
ABSTRACT
@#Objective To analyze the outcomes of complicated congenital heart diseases (CCHD) patients accepting multiple (>2) re-sternotomy operations. Methods We retrospectively analyzed the clinical data of 146 patients undergoing multiple cardiac re-sternotomy operations between 2015 and 2019 in our center. There were 95 males and 51 females with an age of 4.3 (3.1-6.8) years and a weight of 15.3 (13.4-19.0) kg at last operation. Results The top three cardiac malformations were pulmonary atresia (n=51, 34.9%), double outflow of right ventricle (n=36, 24.7%) and functional single ventricle (n=36, 24.7%). A total of 457 sternotomy procedures were performed, with 129 (88.3%) patients undergoing three times of operations and 17 (11.7%) patients undergoing more than three times. Fifty-two (35.6%) patients received bi-ventricular repair, 63 (43.1%) patients received Fontan-type procedures, and 31 (21.2%) patients underwent palliative procedures. Ten (6.8%) patients experienced major accidents during sternotomy, including 7 (4.8%) patients of urgent femoral artery and venous bypass. Eleven (7.5%) patients died with 10 (6.8%) deaths before discharge. The follow-up time was 20.0 (5.8-40.1) months, and 1 patient died during the follow-up. The number of operations was an independent risk factor for the death after operation. Conclusion Series operations of Fontan in functional single ventricle, repeated stenosis of pulmonary artery or conduit of right ventricular outflow tract post bi-ventricular repair are the major causes for the reoperation. Multiple operations are a huge challenge for CCHD treatment, which should be avoided.
ABSTRACT
@#To evaluate the surgical strategy and follow-up for pulmonary atresia with intact ventricular septum (PA/IVS) in our heart center. Methods From January 2008 to December 2018, 151 patients with PA/IVS were divided into two groups: a one-stage surgery group (26 patients), including 17 males and 9 females at an average age of 14.7±13.2 months, and a staged surgery group (125 patients) including 72 males and 53 females at an average age of 6.4±6.3 months. The clinical effectiveness of the two groups were analyzed. Results All patients were followed up for 1-11 years. Eighteen patients died and 19 patients were lost to follow-up. The 1-year, 5-year and 10-year survival rate was 90.2%, 87.0%, and 85.2%, respectively. Two patients died in the one-stage surgery group. Twelve patients died after initial surgery, and 4 patients died after final operation in the staged surgery group. The Z value of tricuspid valve (P=0.013) and severe right ventricular dysplasia (P=0.025) were the risk factors of postoperative death in the patients with PA/IVS. Furthermore, 58 patients completed final operation, and the total number of the final operation (including one-stage radical surgery) accounted for 55.6% (84/151). Five patients accepted the re-operation intervention in the medium-term follow-up. The rest of the patients recovered well. Only 2 patients were classified as grade Ⅲ in cardiac function, and the rest patients were classified as gradeⅠ-Ⅱ. Conclusion According to the degree of right ventricular hypoplasia, the age at operation and the presence or absence of coronary artery malformation, the individualized surgical strategy could significantly improve the success rate of PA/IVS, and early completion of right ventricular decompression operation is conducive to improve the chance for biventricular repair.
ABSTRACT
Objective Ebstein anomaly is a rare type of tricuspid malformation. The present surgical methods to resolve this anomaly include tricuspid valvuloplasty, palliative surgery, and tricuspid valve replacement. The purpose of this study was to evaluate the short- and midterm outcomes of different surgical treatments among children with Ebstein anomaly. Methods This was a retrospective study of 136 Ebstein anomaly patients undergoing surgery at our institution from January, 2006 to August, 2015. This cohort included 118 patients receiving tricuspid valvuloplasty, 14 patients receiving palliative surgery and 4 patients receiving tricuspid valve replacement. Results There were two in-hospital deaths and one delayed death 6 months after bidirectional cavopulmonary shunt during a second-stage operation; thus, the mortality rate was 2.2% (3/136). The follow-up variables included echocardiography, chest radiography, oxygen saturation, and cardiac function. After a mean follow-up duration of 35.8 ± 16.5 months (range: 6-98 months), all survivors had no indications for reoperation; the oxygen saturation following radical surgery and palliative surgery was 95 to 100% and 85 to 95%, respectively. Most of the patients exhibited an improved New York Heart Association (NYHA) functional class from III or IV preoperatively to I or II at follow-up; only two patients who underwent the Fontan procedure continued to exhibit NYHA functional class III. In most patients, tricuspid regurgitation (TR) degree decreased from moderate or severe preoperatively to mild or moderate at follow-up and only six patients continued to exhibit severe TR at follow-up. Conclusions Individualization of surgical methods based on different indications, including age, associated malformations, tricuspid anatomy, cardiac function, and intraoperative status, could effectively improve the outcomes of Ebstein anomaly patients.

Objective To avoid complications associated with the complete Senning procedures and to assist right-heart hemodynamics, this study was undertaken to assess the risks and benefits of the double-switch operation using a hemi-Mustard atrial switch procedure and the bidirectional Glenn operation for congenitally corrected transposition of the great arteries. we fa-vor a modified atrial switch procedure. Methods Between January 2014 and March 2016, anatomic repair was achieved in 26 patients. A hemi-Mustard procedure was the atrial switch procedure for 26. 9％(7/26). The Rastelli-atrial switch procedure was performed in 5 patients( RAS) and the arterial-atrial switch procedure was performed in 2 patients( AAS) . Results There was no in-hospital death after anatomic repair. There were no late deaths in a median follow-up of 7-21 months. Glenn opera-tion complications were uncommon limited to the perioperative period, atrial baffle-related reoperations or sinus node dysfunc-tion had not been observed. Tricuspid regurgitation decreased to mild for 1 case and mild to moderate for 6 cases. Right ventri-cle-pulmonary artery conduit longevity was significantly improved. Conclusion We recentely describe an experience with the double-switch operation using a modified atrial switch procedure with favorable earlyterm results. The risks of the hemi-mustard and bidirectional Glenn operation are minimal and are limited to a well-defined patient subset. The benefits include reduced baffle-and sinus node-related complications, technical simplicity and inspiring results.
ABSTRACT
Objective To explore risk factors of cardiac surgery in neonates with low body weight.Methods Retrospective analysis was made in neonates weighing less than 3 kg at surgery(n =192;group 1) and 3 to 6 kg(n =517;group 2),who had undergone open cardiac repairs from January 2006 to December 2015 at our institution.Patients were grouped according to the primary procedure performed and analyzed according to their weight at the time of surgical intervention.Patients were also analyzed according to preoperative risk scores.Univariate versus multivariate risk analysis was performed.Results Hospital early mortality in group 1 was 25.0％ (n =48) versus 14.5 ％ (n =75) in group 2 (P =0.001).Compared with group 2,neonates in group 1 had a significantly higher mortality for simple arterial switch procedure.Lower body weight remained strongly associated with mortality risk after stratifying the population by preoperative risk scores category levels 2.Within group 1,age,weight at surgery,preoperative risk score and type of procedure were not associated with significant differences in early mortality.Cardio-pulmonary bypass time,aortic cross-clamp time and the presence of a surgical complication were independent risk factors for early mortality in group 1.Conclusion Among neonates weighing less than 3.0kg who underwent open cardiac surgery,perioperative hemodynamic status,reflected by bypass time,cross-clamp time,and surgical complications,strongly influenced early mortality.In contrast,low body weight itself was not associated with early mortality.
ABSTRACT
<p><b>OBJECTIVE</b>To retrospectively analyze the experience of one-stage surgical correction for children with congenital heart diseases and tracheal stenosis and further to clear the principle of treatment for these patients.</p><p><b>METHODS</b>From January 2006 to June 2013, 48 patients with congenital heart diseases and tracheal stenosis underwent surgical correction. There were 36 male and 12 female patients. The mean age at operation was (23 ± 27)months (range: 3-72 months) and the mean weight was (12 ± 8) kg (range: 3.4-46.0 kg). The underlying diagnoses were pulmonary sling in 33 patients, double aortic arch in 3, tetrology of Fallot in 6, ventricular septal defect in 4, double outlet right ventricle in 1, and pulmonary atresia in 1 patient. Among them, short tracheal stenosis was present in 15, long tracheal stenosis in 25 and bridging bronchus in 8 patients. Repairs with autogenous tracheal tissue were performed in 6, and end-to-end anastomosis in 11 and slide tracheoplasty in 31 patients. Two patients had granulation tissue growing in the airway postoperatively and were re-operated by autogenous rib tissue. All of patients were followed up after operation 1, 3, 6, 12 months and if the patient had symptoms that should be examined by bronchoscopy. The patients should be examined by CT post-operation one year.</p><p><b>RESULTS</b>There were 7 deaths in all 48 cases and the early mortality was 14.6%. Two deaths were not related to tracheal stenosis, and other 5 were associated with long segment tracheal stenosis. Forty-one patients were followed for 2 months to 6 years, and no patients required re-operations. Clinical symptoms of tracheal stenosis disappeared and the results of CT scan were satisfied.</p><p><b>CONCLUSIONS</b>One stage surgical repair of the patients with congenital heart diseases and tracheal stenosis have a good effect. Slide tracheoplasty is the effective surgical method for long segment tracheal stenosis. Postoperative granulation tissue growing in the airway is the leading cause of death.</p>
