  • 利用自动病变检测规划立体定向脑电图:可行性回顾性研究

    本回顾性横断面研究评估了将深度学习的难治性癫痫患儿的结构性磁共振成像(MRI)纳入到规划立体定向脑电图(SEEG)植入的可行性和潜在益处。本研究旨在评估自动病变检测与 SEEG 检测出癫痫发作起始区(SOZ)之间的共定位程度。将神经网络分类器应用于基于皮层 MRI 数据的三个队列:① 对 34 例局灶性皮质发育不良(FCD)患者的神经网络进行学习、训练和交叉验证;② 对 20 名健康儿童对照者进行特异性评估;③ 对 34 例患儿纳入 SEEG 植入计划的可行性进行了评价。SEEG 电极触点的坐标与分类器预测的病变进行核验。临床神经生理学家鉴定癫痫发作起源和易激惹区的 SEEG 电极触点位置。若 SOZ 坐标点和分类器预测的病变之间的距离<10 mm 则被认为是共定位的。影像学诊断病灶的分类敏感度为 74%(25/34)。对照组中未检测到异常(特异性=100%)。在 34 例 SEEG 植入患者中,21 例有局灶性皮层 SOZ,其中 8 例经病理证实为 FCD。分类器正确地检测了这 8 例 FCD 患者中的 7 例(86%)。组织病理学存在异质性的局灶性皮层病变患者中,62% 的患者分类器输出结果与 SOZ 之间存在共定位。3 例患者中,电临床提示为局灶性癫痫,SEEG 上无 SOZ 定位点,但在这些患者中,分类器识别了尚未植入的额外异常点。自动病变检测与 SEEG 之间的共定位存在高度的一致性。 我们已经建立了一个框架,将基于深度学习的 MRI 自动病变检测纳入到 SEEG 植入计划。我们的发现支持了对自动 MRI 分析的前瞻性评估,以规划最佳电极植入轨迹方案。

  • Influence of Drug Repercussion by Pediatric Hospital Inpatients on Nursing Work

    ObjectiveTo explore the appropriate intervention measures to reduce the influence of drug repercussion by pediatric hospital inpatients on nursing work. MethodBetween March 1st and 28th, 2014, statistical analysis on the characteristics of pediatric drug-return by drug repercussion questionnaires was carried out. ResultsEach drug repercussion took much time of the nurses (median of 5.00 minutes per time). The frequency of drug repercussion in the internal medicine department was more than that in the surgical department; the most drug repercussions were found in the respiratory medicine department, reaching 26.84%. The main category of drug repercussion was aerosolized medication (39.32%). The drug repercussion mainly resulted from lack of patients' education and doctor-related administration, which had a proportion of 31.44% and 27.19%, respectively. ConclusionsThe wards which have more drug repercussions should be under the supervision according to the analysis of drug repercussion. Meanwhile, improving patients' education and training of medical staff can reduce the pediatric hospital inpatients' drug repercussion and also may reduce the bad effects on nursing work.

  • Analysis of registered industry-sponsored clinical trials of pediatric drugs in China

    ObjectiveTo review the characteristics of registered industry-sponsored clinical trials of pediatric drugs and vaccines in China and to provide references for promoting the development of new pediatric drugs. MethodsWe searched ClinicalTrials.gov and the Chinese Clinical Trial Registry for completed registered industry-sponsored clinical trials of pediatric drugs and vaccines from the database inception to September 11, 2022. Data including the date the trial was first posted, product type (drug or vaccine), sample size, and other information to describe the general characteristics of pediatric clinical trials were collected. The studies were divided into 2 phases based on the trial posted date, 2005―2010 and 2011―2022, reflecting the enactment of pediatric drug clinical trial policies in recent years. The quality of trial registration and the main characteristics of interventional trials in the 2 phases were then compared. Exploring the results attached to industry and non-industry sponsored clinical trials. ResultsData for 145 trials were collected, and the largest proportion (63.4%) involved vaccines. Randomized control trial (RCT) was the study type with the highest percentage (68.3%). The average report completion rate for registered interventional trials was 81.0%. Compared with 2005―2010, the percentage of average report completions, pediatric drug clinical studies, multicenter, RCTs, and double-blinded registered trials increased in 2011―2022. The proportion of positive outcomes in pediatric clinical trials sponsored by industries was higher than those sponsored by non-industry. ConclusionThe majority of completed pediatric clinical trials sponsored by industries are for vaccines, in line with the promotion of pediatric policies. The quality of trial registration has improved, but not significantly, and some characteristics of trial design have changed. The proportion of positive outcomes in pediatric clinical trials sponsored by industries is higher. And further promotion of pediatric clinical trials is needed.

  • An attention-guided network for bilateral ventricular segmentation in pediatric echocardiography

    Accurate segmentation of pediatric echocardiograms is a challenging task, because significant heart-size changes with age and faster heart rate lead to more blurred boundaries on cardiac ultrasound images compared with adults. To address these problems, a dual decoder network model combining channel attention and scale attention is proposed in this paper. Firstly, an attention-guided decoder with deep supervision strategy is used to obtain attention maps for the ventricular regions. Then, the generated ventricular attention is fed back to multiple layers of the network through skip connections to adjust the feature weights generated by the encoder and highlight the left and right ventricular areas. Finally, a scale attention module and a channel attention module are utilized to enhance the edge features of the left and right ventricles. The experimental results demonstrate that the proposed method in this paper achieves an average Dice coefficient of 90.63% in acquired bilateral ventricular segmentation dataset, which is better than some conventional and state-of-the-art methods in the field of medical image segmentation. More importantly, the method has a more accurate effect in segmenting the edge of the ventricle. The results of this paper can provide a new solution for pediatric echocardiographic bilateral ventricular segmentation and subsequent auxiliary diagnosis of congenital heart disease.

  • Robustness assessment of pediatrics meta-analysis using fragility index

    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.

  • Survey on Off-Label Drug Use in Pediatric Outpatients of West China Second University Hospital in 2010

    Objective To determine the extent of off-label drug use in pediatric outpatients of West China Second University Hospital in 2010, and to analyze its possible risk factors, so as to provide baseline data for getting acquainted with the extent of off-label drug use in pediatrics in China and developing policy of off-label drug use. Methods The stratified random sampling was conducted to select prescriptions of children aged 0 to 18 years in pediatric outpatients of the West China Second University Hospital in 2010. According to drug instructions, 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. In addition, an analysis was conducted to check the relationship between off-label use and following possible risk factors: age, sex, essential medicines and over-the-counter drugs. Results A total of 2 640 prescriptions with 8 588 medical advices involving 329 drugs were extracted and analyzed, with incidence rates of off-label drug use accounting for 76.59%, 40.88% and 83.89%, respectively. The main categories of off-label drug use were no pediatric information (35.57%), indication (25.44%), and dosage (25.31%). The top 2 age groups with highest incidence rate of off-label drug were neonates (54.35%) and adolescents (49.64%). The top 4 drugs with highest incidence rate of off-label drug were respiratory system medicines (48.12%), Chinese patent medicines (48.12%), digestive and metabolic system medicines (33.36%), and systemic anti-infectives (16.27%). The off-label use risks in all age groups in the hospital were indifferent, and the essential medicines and prescription medicines were likely to present higher risks of drug off-label. Conclusion Off-label drug use in pediatric outpatients is common with growth trend in pediatric outpatients of the West China Second University Hospital. On the one hand, drug instructions lack pediatric information, and on the other hand, it’s badly in need of developing relevant legislation, regulations or guidelines to regulate off-label drug use, providing more evidence by conducting clinical trials on pediatric drugs, encouraging the development and production of the applicable drugs and dosage forms for children, and establishing the children essential medicine list, so as to avoid doctor’s professional risk and ensure the safety of pediatric drug use.

  • Reporting Quality of Systematic Reviews and Meta-analyses Published in Chinese Pediatric Journals: A Retrospective Study

    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.
