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.
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.
Objective To evaluate the cost-effectiveness of chemotherapy in children with newly diagnosed Hodgkin lymphoma at low-, intermediate-, and high-risk. Methods From the perspective of health system, a decision-tree model was designed for cost-effectiveness analysis. The chemotherapy regimens of low-risk group included OEPA (vincristine, etoposide, prednisone, doxorubicin), AV-PC (doxorubicin, vincristine, prednisone, cyclophosphamide), and ABVD (doxorubicin, bleomycin, vincristine, dacarbazine); intermediate-risk group included OEPA, ABVE-PC (doxorubicin, bleomycin, vincristine, etoposide, prednisone, cyclophosphamide) and ABVD; high-risk group included OEPA, ABVE-PC, ABVD and BEACOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, prednisone). The effectiveness and cost parameters were derived from the event-free survival rate reported in the literature, the drug linked reference price in Sichuan province, and treatment price of medical institutions. Univariate and probabilistic sensitivity analysis were performed to explore the impact of uncertainty. Results In the low-risk group, compared with AV-PC, the incremental cost-effectiveness ratios (ICER) of OEPA and ABVD were 80 700 yuan and 108 799 yuan, respectively. In the intermediate-risk group, compared with OEPA, the ICER of ABVE-PC and ABVD were −17 737 yuan and −4 701 yuan respectively. In the high-risk group, compared with ABVE-PC, the ICER of OEPA, ABVD and BEACOPP were 149 262, 472 090 and 64 652 yuan, respectively. Univariate sensitivity analysis showed that in low-risk group, the most influential factors were cost of OEPA and cost of ABVD; in moderate-risk group were cost of ABVE-PC and cost of OEPA; in the high-risk group were cost of OEPA, cost of ABVD, and cost of BEACOPP, respectively. The results of probabilistic sensitivity analysis are basically consistent with those of the main analysis. Conclusion If China's per capita gross domestic product in 2023 (89 358 yuan) was used as the willingness-to-pay (WTP) threshold, OEPA in the low-risk group, OEPA in the intermediate-risk group and BEACOPP in the high-risk group are cost-effective.
Objective To explore the interference of recent use of antibiotics in the sensitivities of different methods for the detection of Helicobacter pylori (Hp) in children. Methods From June 2015 to December 2017, children who were highly suspected of Hp infection and required gastroscopy were divided into the antibiotic group and the control group according to the recent use of antibiotics, with 200 cases in each group. The use of antibiotics of children in the antibiotic group was analyzed. The children in the two groups completed five methods of Hp detection, including rapid urease test (RUT), 13C-urea breath test (13C-UBT), pathological Warthin-Starry staining, colloidal gold method for measuring Hp immunoglobulin M (IgM) antibody, and enzyme linked immunosorbent assay method for measuring Hp stool antigen (HpSA). Comparative analyses of data were done. Results The positive rate of RUT was 36.5% in the antibiotic group and 75.0% in the control group (P<0.05). The positive rate and value of13C-UBT were 59.0% and 13.6±4.7 in the antibiotic group, and 78.0% and 41.7±6.6 in the control group (P<0.05). The positive rate of pathological biopsy was 48.0% in the antibiotic group and 68.0% in the control group (P<0.05), and L-forms were found in 80.9% of the Hp-positive specimens in the antibiotic group. The positive rate of IgM antibody was 54.5% in the antibiotic group and 65.5% in the control group (P<0.05). The positive rate of HpSA was 38.0% in the antibiotic group and 69.0% in the control group (P<0.05). In the antibiotic group, only 12.5% of the children used antibiotics for eradication of Hp and 87.5% for non Hp eradication. Conclusions Under the interference of antibiotics use, the sensitivity of 13C-UBT is the highest among the five methods for Hp detection, and the sensitivities of RUT and HpSA are very low. For children who could not cooperate with 13C-UBT, the sensitivity of IgM detection is relatively high. For children who need gastroscopy, prolonged chromogenic time for RUT and multi-point pathological biopsy can reduce misdiagnosis.
With the development of surgical technology and the need of clinical, transesophageal echocardiography is more and more favored by clinicians. Although the transesophageal echocardiography has developed more than 20 years, yet it has not been widely used in operation at present in domestic. In addition, its application in surgery of children is more rare. It has been confirmed that intraoperative use of transesophageal echocardiography has good safety and wide range of application. We will summarize indications, complications, and the progress of the current technology from the scope of transesophageal echocardiography in pediatric surgery.
Objective We aimed to determine the efficacy and complication of sevoflurane maintenance in children. Methods Trials were collected through electronic searches of MEDLINE, EBSCO, OVID, Springer, Foreign Journals Integration System, CNKI, and CMBdisk (from the date of building the database to April 2008). We also checked the bibliographies of retrieved articles. Results A total of 20 trials involving 1 592 patients were included. The Metaanalysis showed: ① Recovery time: sevoflurane was similar with propofol [WMD=0.22, 95%CI (–2.86, 3.30)], but slower than desflurane [WMD=5.01, 95%CI (2.87, 7.16)], and faster than isoflurane [WMD= –0.55, 95%CI (– 0.74, –0.37)]; ② Discharge time: sevoflurane was similar with propofol [WMD= –4.39, 95%CI (–10.02, 1.25)], desflurane[WMD=1.13, 95%CI (–3.25, 5.51)], and isoflurane [WMD= –8.17, 95%CI (–17.94, 1.60)]; ③ Postoperative agitation: sevoflurane was much more obvious than propofol [RR=5.53, 95%CI (2.99, 10.21)], but superior than desflurane [RR=0.55, 95%CI (0.35, 0.88)], and similar with isoflurane [RR=1.24, 95%CI (0.85, 1.800]; ④ Postoperative nausea and vomiting (PONV): sevoflurane was much more severe than propofol [RR=2.17, 95%CI (1.21, 3.90)], and no difference with desflurane [RR=0.88, 95%CI (0.61, 1.25)]; ⑤ Oculocardiac reflex: sevoflurane was less than propofol [RD= – 0.42, 95%CI (–0.56, –0.27)], and no difference with desflurane [RR=0.93, 95%CI (0.61, 1.41)]. Conclusion The limited current evidence shows no difference between sevoflurane and propofol in recovery time, while the effect of sevoflurane is faster than isoflurane and slower than desflurane. There are no differences among sevoflurane, desflurane, isoflurane, and propofol in discharge time. The incidence of postoperative agitation of sevoflurane is higher than that of propofol, but lower than that of other inhaled anesthetics. The incidence of PONV of sevoflurane is higher than that of propofol. The incidence of oculocardiac reflex of sevoflurane is lower than that of propofol and similar with that of desflurane.
ObjectiveTo evaluate the health economics indexes of day surgery mode and traditional specialist hospitalization mode, and to provide reference for the selection of different hospitalization mode of inguinal-type cryptorchidism in children.MethodsThe patients with unilateral cryptorchidism under 5 years old between January 2017 and January 2018 in Chongqing Children’s Hospital were selected in this study. According to different inpatient surgery modes, the included children were divided into day surgery group (day group) and special in-hospital surgery group (specialty group). The general data of patients, treatment indicators, incidence of complications, postoperative testicular atrophy rate, recurrence, nosocomial infection, hospitalization time, hospitalization cost, satisfaction of patients, and other health effect indicators between the two operation modes were compared. The treatment effect indexes and cost-effect ratio of the two modes were statistically analyzed.ResultsA total of 198 children were included, including 83 in the day group and 115 in the specialty group. The patients in both groups underwent orchiopexy by small inguinal dermatoglyph and scrotal incision. There was no statistically significant difference in the affected side, source area, postoperative complications, or nosocomial infection between the two groups (P>0.05). The patients in the specialty group were older than those in the day group [(27.60±11.04) vs. (20.88±9.48) months old; t=4.586, P<0.001]; the bed occupancy time [(118.60±10.80) vs. (23.95±5.90) h; t=72.353, P<0.001] and operation time [(0.45±0.15) vs. (0.38±0.12) h; t=2.946, P=0.004] in the specialty group were longer than those in the day group. The difference was statistically significant in hospitalization expenses between the two groups (χ2=155.374, P<0.001); 92.8% of the children in the day group spent less than 5 000 yuan, while 95.7% of the children in the specialty group spent more than 5 000 yuan. The American Society of Anesthesiologists scores in the specialty group were higher than those in the day group (χ2=44.870, P<0.001). The treatment effect indexes in the day group and the specialty group were 0.99 and 1.01, respectively, and the cost-effect ratios were 3 850 and 6 657, respectively. The economic benefit of the day group was better.ConclusionsThe cost-effectiveness of day surgery is better than that of specialized inpatient surgery. Therefore, this model can be recommended for children who meet the indications of day surgery.
ObjectiveTo evaluate the robustness of pediatrics clinical evidence-based evidence using fragility index and to explore the factors influencing fragility index. MethodsWe searched the PubMed, Embase, and Scopus databases to collect relevant literature on systematic reviews and meta-analyses in the field of pediatrics, and calculated the fragility index. The rank sum test was used to compare differences between groups with different outcome types, different levels of statistical significance, and different sample sizes. Spearman correlation analysis was used to explore the association between the fragility index and sample size, as well as the year of publication. ResultsA total of 152 systematic reviews, including 573 meta-analyses, were included, with a median fragility index of 6 (3, 10). Most meta-analyses chose the risk ratio (RR) as the effect measure (387/573, 67.5%), the Mantel-Haenszel method (412/573, 71.9%) as the synthesis method, and the fixed-effect model (300/573, 57.4%) as the assumed model. The Mann-Whitney test showed no statistically significant difference in the fragility index between meta-analyses with safety outcomes and those with efficacy outcomes (P=0.397), and no statistically significant difference between meta-analyses with significant results and those with non-significant results (P=0.520). The Kruskal-Wallis test found a statistically significant difference in sample size among groups with different fragility indices (P<0.001). Spearman correlation analysis found a positive correlation between the fragility index and sample size (ρ=0.39, P<0.001), but no statistically significant correlation with the year of publication (P=0.235). ConclusionThe fragility index of systematic review and meta-analysis published in pediatrics journals is generally low, and the robustness of the results is not high, so it is necessary to be cautious when making evidence-based decisions. Furthermore, the larger the sample size included in the meta-analysis, the higher the fragility index, and incorporating more trials and populations can facilitate the increase in the robustness of the meta-analysis results.
