Objective To explore the use of ChatGPT (Chat Generative Pre-trained Transformer) in pediatric diagnosis, treatment and doctor-patient communication, evaluate the professionalism and accuracy of the medical advice provided, and assess its ability to provide psychological support. Methods The knowledge databases of ChatGPT 3.5 and 4.0 versions as of April 2023 were selected. A total of 30 diagnosis and treatment questions and 10 doctor-patient communication questions regarding the pediatric urinary system were submitted to ChatGPT versions 3.5 and 4.0, and the answers to ChatGPT were evaluated. Results The answers to the 40 questions answered by ChatGPT versions 3.5 and 4.0 all reached the qualified level. The answers to 30 diagnostic and treatment questions in ChatGPT 4.0 version were superior to those in ChatGPT 3.5 version (P=0.024). There was no statistically significant difference in the answers to the 10 doctor-patient communication questions answered by ChatGPT 3.5 and 4.0 versions (P=0.727). For prevention, single symptom, and disease diagnosis and treatment questions, ChatGPT’s answer scores were relatively high. For questions related to the diagnosis and treatment of complex medical conditions, ChatGPT’s answer scores were relatively low. Conclusion ChatGPT has certain value in assisting pediatric diagnosis, treatment and doctor-patient communication, but the medical advice provided by ChatGPT cannot completely replace the professional judgment and personal care of doctors.
Objective To evaluate the diagnosis value of purified protein derivative (PPD) antibody tests in childhood tuberculosis. Methods We reviewed 126 cases of hospitalization children tested body fluid PPD antibody by Enzyme-Linked Immunosorbent Assay (ELISA). Twenty-two them were diagnosed with tuberculosis. We determined the sensitivity, specificity, diagnostic likelihood ratio, positive prognostic value, negative prognostic value, post-test probability, respectively. Results The following accuracy statistics for the PPD body liquid antibody tests in this study: sensitivity, 45.45%; specificity, 91.35%; diagnostic likelihood ratio positive, 5.25; diagnostic likelihood ratio negative, 0.597; positive predictive value, 52.63%; negative predictive value, 88.79% and post-test probability, 48.09% in 15% of prevalence. Conclusion This study shows that body fluid PPD tests have limited value for diagnosis of tuberculosis in pediatric tuberculosis. Clinic physicians should be wary of the positive results of body fluid PPD antibody tests. The value of diagnosis is related to prevalence of tuberculosis in the specific hospital.
Objective To determine the extent of off-label drug use in Pediatric Wards of West China Second University Hospital in 2010 and analyze its risk factors, so as to provide baseline data for getting acquainted with the extent of off-label drug use in pediatrics in China, and for making policies of off-label drug use. Methods The proportionate stratified random sampling was conducted to select medical advice and discharge medication for hospitalized children in Pediatric Wards in 2010. According to drug instructions, the off-label drug use of prescriptions of all selected children was analyzed in the following aspects, the category of off-label drug use, age, category of drugs and wards. In addition, a logistic regression was done that modeled the odds of receiving an off-label prescription as a function of the following possible risk factors: age, sex and the rank of doctors. Results The total 749 children were selected, and 14 374 prescriptions involving 385 drugs were analyzed. The rate of off-label drug use was 98.00%, 78.96% and 88.05% in children, prescriptions and drug categories, respectively. The main categories of off-label drug use were no pediatric information (29.41%), indication (18.35%), dosage (17.61%) and dosage range (±20%) (13.52%). The top 2 age groups of off-label drug use were adolescents (83.56%) and children (80.58%). The top 4 drugs of off-label use were those for alimentary tract and metabolism (82.28%), anti-infectives for systemic use (75.06%), blood and blood forming organs (79.27%) and respiratory (58.27%). The top 2 wards of off-label drug use were Pediatric Hematology (88.27%) and Neonates (79.12%). In hospital, children, adolescents and male patients had higher risk factors of off-label drug use, and doctors with senior rank prescribed more off-label prescriptions than those with intermediate rank. Conclusion The off-label drug use in Pediatric Wards is common in West China Second University Hospital. On the one hand, drug instructions lack the pediatric information, and, on the other hand, it’s badly in need of developing relevant legislations, regulations or guidelines to regulate off-label drug use, in order to avoid doctor’s professional risks and ensure the safety of pediatric drug use.
ObjectiveTo carry out a retrospective study of the reporting quality and current situation of the systematic reviews (SRs)/meta-analyses (MAs) in pediatric field in China, as well as compliance with the PRISMA and MOOSE guidelines. MethodsSeven core Chinese pediatric journals were hand-searched. Two reviewers extracted data independently using predesigned data extraction form, crosschecked data, and discussed to solve discrepancy. The PRISMA and MOOSE guidelines were used to assess the reporting quality respectively, and subgroup analysis was conducted by different total cites and different published time. SPSS 22.0 was used to for statistical analysis. Percentage was used to describe categorical data and Chi-square test was used to compare the difference among groups. ResultsA total of 157 SRs/MA were included. The proportion of SRs/MA related to interventions was the biggest (61.1%, 96 SRs/MA). (1) The coincidence rate of SRs/MA related to interventions in the PRISMA checklist was better:the coincidence rate of twenty entries was above 50%; (2) The coincidence rate of observational SRs/MA in the MOOSE guidelines was not so good:the coincidence rate of 15 entries was less than 50%, even some of them were less than 20%. There were no significant difference between different total cites (≤5 vs. > 5) in PRISMA and MOOSE guidelines. (3) The coincidence rate of SRs/MA related to interventions had been improved to some extent in most of items after the PRISMA guidelines published, and the differences were statistically significant respectively in No. 8, 19, 20, and 23 (P≤0.05). ConclusionsThe number of SRs/MA published in the pediatric journals in China is increasing generally, the coincidence rate of SRs/MAs related to interventions have been obviously improved after the PRISMA guidelines published, and it's better than the coincidence rate of observational SRs/MAs in MOOSE guidelines. In a word, we should pay more attention to the quality of SRs/MAs, but not just the number.
Abstract： Objective To analyze the manifestation, treatment，outcome and potentially predisposing risk factors of perioperative thromboembolism after cavo-pulmonary connection, and to assess the effects of our prophylactic antithrombotic strategy. Methods Clinical data of 264 cases of bidirectional Glenn and 224 cases of total cavopulmonary connection （TCPC） operations undertaken from September 2005 to December 2010 in Fu wai hospital were retrospectively analyzed. Perioperative thromboembolic complications occurred in 9 patients. 5 of them were after bidirectional Glenn, 4 were after TCPC. Most of the 9 patients had at least one thrombi-related risk factor. The routine prophylactic antithrombotic therapy after these operations were intravenous infusion of heparin 10 U/（kg·h） initially, followed with oral aspirin 1-3 mg/（kg·d）. Results Thromboembolic events occurred within 7 days after the operation in 6 cases, appeared 2 to 4 weeks after the surgery in 3 cases. All 9 patients received anticoagulation with heparin. One patient also undertook take-down operation. 3 （33%） patients died, accounting for 33% （1/3）, and 18% （2/11） of the early deaths after bidirectional Glenn and TCPC operations. Clinical symptoms improved or disappeared in the remaining 6 patients. Conclusion The mortality of perioperative thromboembolic complications after cavo-pulmonary connection is high, consisting of the important cause of early deaths after these procedures. Our prophylactic anticoagulation strategy proved to be effective, though some thrombi-relatedrisk factors still need to be avoided.
ObjectiveTo analyze the perdictive value of Screening Tool for the Assessment of Malnutrition in Pediatrics (STAMP) for malnutrition or postoperative complications in children with critical congenital heart disease (CHD).MethodsA total of 875 children with critical CHD who were hospitalized in West China Hospital, Sichuan University form August 2019 to February 2021, including 442 males and 433 females with a median age of 30 (12, 48) months, were assessed by STAMP in Health Information System. Clinical data of postoperative complications were collected.Results(1) Based on World Health Organization Z-score as gold standard, 24.5% had malnutrition risk, and 34.3% were diagnosed with malnutrition. According to STAMP, the children were with medium malnutrition risk of 37.9% and high malnutrition risk of 62.1%. There was a statistical difference of incidence rate of malnutrition and detection rate of STAMP malnutrition risk in gender, age, ICU stay or length of mechanical ventilation (P<0.05); (2) with the optimal cut-off point of 5.5 in STAMP for malnutrition, the sensitivity, specificity, positive predictive value, negative predictive value and area under the curve (AUC) were 68.3%, 84.3%, 48.1%, 88.3% and 0.82, respectively; (3) 12.0% of the children were with postoperative complications; (4) with the optimal cut-off point of 5.5 in STAMP for postoperative complications, the sensitivity, specificity, positive predictive value, negative predictive value and AUC were 83.8%, 73.1%, 18.8%, 99.1% and 0.85, respectively.ConclusionChildren with critical CHD have a higher incidence of malnutrition risk and postoperative complications. STAMP has a good perdictive value for malnutrition or postoperative complications, however, the sensitivity and specificity of STAMP are affected by the gold standard or the cut-off point.
Objective To investigate the effect of quality control circle in reducing ventilator-associated pneumonia in Pediatric Intensive Care Unit (PICU). Methods A total of 1 249 child patients who underwent mechanical ventilation between January and December 2013 were chosen as the control group, and they accepted routine management. Another 1 208 child patients treated between January and December 2014 were selected as the observation group, and quality control circle was adopted. The compliance of ventilator care bundles, the duration of mechanical ventilation, the length of PICU stay and the incidence of ventilator-associated pneumonia were compared between the two groups. Results Compared with the control group, compliance of ventilator care bundles was higher in the observation group (P<0.01), the duration of mechanical ventilation was shorter [(6.9±2.4) daysvs. (4.6±2.2) days], the length of PICU stay was shorter [(9.2±3.1) daysvs. (7.7±2.4) days], and the incidence of ventilator-associated pneumonia was lower (22.4‰vs. 9.1‰) (P<0.05). Conclusion Application of quality control circle can significantly promote the compliance of ventilator care bundles, and decrease the duration of mechanical ventilation, the length of PICU stay and the incidence of ventilator-associated pneumonia.
Objective To discuss the criteria of recipient selection，surgical approach，and complications and its theray by using of pediatric donation after cardiac death liver graft in adult recipient. Methods The clinical data of one case of pediatric donation after cardiac death liver to adult recipient was analyzed retrospectively and the literatures were reviewed. Results A 6-year-old girl pronounced brain death due to drowning and on the basis of cardiopulmonary criteria donated the organ．The liver graft weight was 598 g and the warm ischemic time was 10 min. The liver donor was transplanted to a 64-year-old woman，the graft to recipient weight ratio was 1.09%，the graft volume/estimated standard liver volume was 61.8%．The classic orthotopic liver transplantation without bypass was underwent，the postoperative recovery was smooth after the liver transplantation．The CT scan showed that the liver graft volume was 1 003cm3 on day 14 after operation．The patient was discharged on 45 d after orthotopic liver transplantation and the liver function was normal when followed-up 3 months after the operation. Conclusions Pediatric donation after cardiac death liver graft can be successfully utilized to adult recipient．Recipient selection and surgical approach should be decided by conditions of both donor and graft．
ObjectiveTo investigate the effect of delayed sternal closure (DSC) on sternal wound debridement after pediatric cardiac surgery. MethodsWe retrospectively analyzed clinical data of 491 pediatric patients underwent DSC in Guangdong General Hospital between June 2009 and June 2014. There were 333 males and 158 females with age of 1 day to 153.37 (5.68±17.24) months. The rate of sternal wound debridement between the DSC patients and the non-DSC patients was compared. ResultsA total of 454 pediatric patients with DSC initiated in the operation room. And 37 patients with DSC initiated in intensive care unit after emergency sternotomy. A total of 392 patients with delayed sternal closure were discharged. Eight patients gave up treatment for family reasons and 91 patients died. Patients with DSC had higher incidence of sternal wound debridement than the patients with non-DSC did (χ2=6.693, P=0.010). ConclusionDSC is an effective treatment for children with severe cardiac surgery, while it causes higher incidence of sternal wound debridement.
ObjectiveTo analyze the short- and long-term therapeutic effects of heart transplantation in children. MethodsA retrospective study was conducted on recipients and donors who underwent heart transplantation at the 7th People’s Hospital of Zhengzhou from May 2018 to August 2023, analyzing their clinical characteristics, surgical data, postoperative complications, and survival rates. ResultsA total of 22 children underwent heart transplantation, including 14 males and 8 females, with a median age of 13.5 (10.0, 15.0) years and a median weight of 41.9 (30.5, 55.4) kg. The primary diseases included: dilated cardiomyopathy in 16 patients, hypertrophic cardiomyopathy in 1 patient, myocardial dysplasia in 3 patients, right ventricular dysplasia in 1 patient, and congenital heart disease with abnormal coronary artery origin in 1 patient. The median age of the donors was 21.0 (13.0, 29.0) years, and the median weight was 50.5 (47.3, 75.0) kg. The blood types of the donors and recipients were the same, with type A in 10 patients, type B in 5 patients, type O in 5 patients, and type AB in 2 patients. Before transplantation, all children had a New York Heart Association cardiac function grade Ⅳ, with 1 patient assisted by intra-aortic balloon pump (IABP), 3 patients assisted by extracorporeal membrane oxygenation (ECMO), 2 patients assisted by continuous renal replacement therapy (CRRT), and 2 patients on mechanical ventilation. Nine patients met the criteria for emergency child status allocation, and the panel reactive antibody level in the patients was<10%. The median cold ischemic time of the donor heart was 355.0 (262.0, 395.5) min, the median aortic cross-clamping time was 45.0 (38.3, 51.3) min, the median mechanical ventilation time was 22.5 (16.8, 52.5) h, the median postoperative hospital stay was 29.5 (20.0, 43.0) d, and the median intensive care unit stay was 6.0 (5.0, 8.3) d. After surgery, 4 patients were assisted by ECMO, 2 patients by CRRT, and 7 patients developed complications, including lung fungal infection in 6 patients, liver and kidney dysfunction in 1 patient, local wound non-union and mediastinal infection in 1 patient, and multiple organ failure in 1 patient. Kaplan-Meier curve analysis showed that the survival rates of children after surgery were 91.3% at 1 year and 3 years; the survival rates of adult heart transplant recipients at our center were 86.7% and 73.8% at 1 year and 3 years, respectively, indicating that the survival rate of children with heart transplantation was higher than that of adult patients. ConclusionHeart transplantation is an effective treatment for end-stage heart failure in children, and the short- and long-term survival rates of children with heart transplantation are superior to those of adults. There are still many difficulties to be solved in pediatric heart transplantation, requiring joint efforts from society and the medical community.
