ABSTRACT
PURPOSE: The purpose of this study was to evaluate the methodological quality of radiomics-based studies for noninvasive, preoperative prediction of Kirsten rat sarcoma (KRAS) mutations in patients with colorectal cancer; furthermore, we systematically evaluate the diagnostic accuracy of predicting models. METHODS: We systematically searched PubMed, Embase, Cochrane Library and Web of Science databases up to 20 April 2022 for eligible studies. The methodological quality of included studies was assessed using the Quality Assessment of Diagnostic Accuracy Studies 2 (QUADAS-2) and Radiomics Quality Score (RQS) tools. A meta-analysis of studies on the prediction of KRAS status in colorectal cancer patients was performed. RESULT: Twenty-nine studies were identified in the systematic review, including three studies on the prediction of KRAS status in colorectal cancer liver metastases. All studies had an average RQS score of 9.55 (26.5% of the total score), ranging from 3 to 17. Most studies demonstrated a low or unclear risk of bias in the domains of QUADAS-2. Nineteen studies were included in the meta-analysis, mostly imaged with magnetic resonance imaging (MRI), followed by computed tomography (CT), positron emission tomography-CT (PET/CT). With pooled sensitivity, specificity and area under the curve (AUC) of the training cohorts were 0.80(95% confidence interval(CI), 0.75-0.84), 0.80(95% CI, 0.74-0.85) and 0.87(95% CI, 0.84-0.90),respectively. The pooled sensitivity, specificity, and AUC for the validation cohorts (13 studies) were 0.78(95% CI, 0.71-0.84), 0.84(95% CI, 0.74-0.90), and 0.86(95% CI, 0.83-0.89), respectively. CONCLUSION: Radiomics is a potential noninvasive technology that has a moderate preoperative diagnosis and prediction effect on KRAS mutations. However, it has not been implemented as a clinical decision-making tool. Future researchers should pay more attention to the methodological quality of the study and further externally validate the model using multicenter datasets.

Purpose: The purpose of this study was to evaluate the diagnostic accuracy of artificial intelligence (AI) models with magnetic resonance imaging(MRI) in predicting pathological complete response(pCR) to neoadjuvant chemoradiotherapy (nCRT) in patients with rectal cancer. Furthermore, assessed the methodological quality of the models. Methods: We searched PubMed, Embase, Cochrane Library, and Web of science for studies published before 21 June 2022, without any language restrictions. The Quality Assessment of Diagnostic Accuracy Studies 2 (QUADAS-2) and Radiomics Quality Score (RQS) tools were used to assess the methodological quality of the included studies. We calculated pooled sensitivity and specificity using random-effects models, I2 values were used to measure heterogeneity, and subgroup analyses to explore potential sources of heterogeneity. Results: We selected 21 papers for inclusion in the meta-analysis from 1562 retrieved publications, with a total of 1873 people in the validation groups. The meta-analysis showed that AI models based on MRI predicted pCR to nCRT in patients with rectal cancer: a pooled area under the curve (AUC) 0.91 (95% CI, 0.88-0.93), sensitivity of 0.82(95% CI,0.71-0.90), pooled specificity 0.86(95% CI,0.80-0.91). In the subgroup analysis, the pooled AUC of the deep learning(DL) model was 0.97, the pooled AUC of the radiomics model was 0.85; the pooled AUC of the combined model with clinical factors was 0.92, and the pooled AUC of the radiomics model alone was 0.87. The mean RQS score of the included studies was 10.95, accounting for 30.4% of the total score. Conclusions: Radiomics is a promising noninvasive method with high value in predicting pathological response to nCRT in patients with rectal cancer. DL models have higher predictive accuracy than radiomics models, and combined models incorporating clinical factors have higher diagnostic accuracy than radiomics models alone. In the future, prospective, large-scale, multicenter investigations using radiomics approaches will strengthen the diagnostic power of pCR.

ABSTRACT
Objectives: When diagnosing Coronavirus disease 2019(COVID-19), radiologists cannot make an accurate judgments because the image characteristics of COVID-19 and other pneumonia are similar. As machine learning advances, artificial intelligence(AI) models show promise in diagnosing COVID-19 and other pneumonias. We performed a systematic review and meta-analysis to assess the diagnostic accuracy and methodological quality of the models. Methods: We searched PubMed, Cochrane Library, Web of Science, and Embase, preprints from medRxiv and bioRxiv to locate studies published before December 2021, with no language restrictions. And a quality assessment (QUADAS-2), Radiomics Quality Score (RQS) tools and CLAIM checklist were used to assess the quality of each study. We used random-effects models to calculate pooled sensitivity and specificity, I2 values to assess heterogeneity, and Deeks' test to assess publication bias. Results: We screened 32 studies from the 2001 retrieved articles for inclusion in the meta-analysis. We included 6737 participants in the test or validation group. The meta-analysis revealed that AI models based on chest imaging distinguishes COVID-19 from other pneumonias: pooled area under the curve (AUC) 0.96 (95 % CI, 0.94-0.98), sensitivity 0.92 (95 % CI, 0.88-0.94), pooled specificity 0.91 (95 % CI, 0.87-0.93). The average RQS score of 13 studies using radiomics was 7.8, accounting for 22 % of the total score. The 19 studies using deep learning methods had an average CLAIM score of 20, slightly less than half (48.24 %) the ideal score of 42.00. Conclusions: The AI model for chest imaging could well diagnose COVID-19 and other pneumonias. However, it has not been implemented as a clinical decision-making tool. Future researchers should pay more attention to the quality of research methodology and further improve the generalizability of the developed predictive models.
ABSTRACT
BACKGROUND: Biomarkers have played an important role in the treatment and management of patients with congenital heart disease (CHD). The 100 most frequently cited articles addressing the possible role of biomarkers assessment in treatment and outcomes in patients with CHD were reviewed. METHODS: The Web of Science Core Collection database was selected as the database for this selection of publications. CiteSpace 5.7.R1 and VOSviewer 1.6.9 were used to analyze the information. RESULTS: A total of 877 articles referencing cardiac biomarkers and CHD were identified in the search period January 1980-June 2020. After screening, the top 100 most cited articles were finally determined. These articles were published in 56 journals, of which the Pediatric Cardiology published the most articles (n=8). Countries collaboration involved a total of 10 countries, and the visualized map indicated the USA had the strongest collaboration network. Related topics of future research will still focus on prevention, general condition evaluation, surgical prognosis evaluation, and application of natriuretic peptide in CHD. CONCLUSIONS: We conducted an insight to acquainting characteristics of highly cited publications of biomarkers in CHD and highlighting the research subjects, global research trends, and network collaboration between countries. Related topics of frontiers will focus on: (I) the application of natriuretic peptide, (II) the diagnostic and prognostic value of genes and their related transcriptional translation agents, (III) the use of biomarkers to evaluate and predict the postoperative injury caused by extracorporeal circulation, (IV) and the application of other biomarkers (such as oxidative stress, homocysteine, and thrombosis) to assess and predict damage circumstance.

BACKGROUND: To analyze the characteristics, related risk factors, and prognosis of lymph node metastasis (Number [No.] 5 and No.6) in the group of adenocarcinoma of esophagogastric junction (AEG). METHODS: The patients with Siewert II AEG who underwent total gastrectomy and D2 lymph node dissection from September 2015 to December 2018 in Lanzhou University Second Hospital were enrolled in this study. The pathological features of the postoperative specimens were analyzed (sex, age, maximum diameter, location, depth of invasion, degree of differentiation, neurological and vascular invasion, etc), and the lymph node metastasis rate of No.5, No.6 groups were calculated. The analysis was performed by IBM SPSS statistical software. The risk factors associated with lymph node metastasis in No.5 and No.6 groups were analyzed. Survival analysis was performed by Kaplan-M method, and survival rate was estimated, Log-rank test was used for comparison, and the difference was statistically significant at Pâ<â.05. RESULTS: There were 142 cases of Siewert type II AEG with the positive rate of No.5 lymph nodes being 10.81% (8/74), and the positive rate of No.6 lymph nodes was 8.33% (11/132). No.5 and No.6 lymph nodes metastasis were not associated with gender, age, tumor maximum diameter, location (cardiac left/cardiac right) (Pâ>â.05), and were associated with invasion depth, differentiation degree, nerve and vascular invasion (Pâ<â.05). In the No.5 lymph node-positive group, the 3-year Overall Survival (OS) was 25.0%, and the No.5 lymph node-negative group had a 5-year OS of 57.8%, which was statistically different (Pâ<â.05). The 3-year OS was 18.2% in No.6 node-positive group and 53.8% in No.6 node-negative group, and the difference was statistically significant (Pâ<â.05). CONCLUSION: For Siewert type II AEG, the lymph node metastasis rate was higher in No.5 and No.6 groups when the tumor invaded all layers of gastric wall and was poorly differentiated complicated with vascular nerve invasion, and the lymph node metastasis rate was lower at 3âyears, which may be more appropriate for total gastrectomy +D2 lymph node dissection.

To summarize and evaluate the efficacy and safety of Shenmai Injection in the treatment of viral myocarditis, shock, pulmonary heart disease, coronary heart disease, neutropenia and tumor chemotherapy, so as to provide supportive evidences for clinical rational use of Shenmai Injection. By searching literatures about studies on the systematic reviews on Shenmai Injection in treatment of viral myocarditis, shock, pulmonary heart disease, coronary heart disease, neutropenia and tumor chemotherapy from the main Chinese and English databases. Primary efficacy and safety outcome measures were selected for comparative analysis and summary, and the appraisal tool of AMSTAR 2 was used to evaluate the included studies.A total of 36 systematic reviews(published from 2005 to 2020) were included, involving viral myocarditis, shock, pulmonary heart disease, malignant tumor and coronary heart disease. The number of cases included in each type of the above diseases was 3 840, 2 484, 12 702, 28 036 and 27 082, respectively. The comparison results showed that, Shenmai Injection combined with conventional/western medicine treatment groups had better efficacy than conventional/western medicine groups alone in the prevention and treatment of the above five diseases. The main adverse reactions of Shenmai Injection reported in the included studies were facial flushing, rash, palpitation, etc., but the incidence was low and the general symptoms were mild, so no special treatment was needed. Therefore, the application of Shenmai Injection on the basis of conventional treatment or western medicine treatment had better prevention and treatment efficacy of the diseases. It was suggested that more multi-center and larger sample-size randomized controlled trials should be carried out in the future, and the relevant reporting standards should be strictly followed in systematic reviews, so as to improve the scientificity and transparency of the study.

Qingkailing Injection is one of the most commonly used traditional Chinese medicine injections with significant clinical application for the treatment of multiple diseases. This study aims to analyze the systematic reviews( SRs) of Qingkailing Injection,in order to provide reference for the clinical application of Qingkailing Injection and the development of relevant clinical practice guidelines. We searched CNKI,CBM,Wanfang,VIP,Pub Med,Cochrane Library and EMbase to collect SRs from the time of database establishment to August 2020. The eligible SRs were included according to the inclusion and exclusion criteria. AMSTAR 2 was used to assess the methodological quality. The diseases,drugs in combinations and results were extracted and analyzed. A total of 24 SRs were selected,including 10 for the treatment of acute cerebrovascular diseases,9 for respiratory infections,2 for viral hepatitis,1 for chronic obstructive pulmonary disease,and two for the adverse effects of Qingkailing Injection. Only three entries of AMSTAR 2 item were fully reported by over 70%,and the rest were reported by less than 70%,with no report about item 2,3 and 10. Twenty-nine outcome indicators were correlated with the included SRs,of which three mostly frequent outcomes were effectiveness,adverse reaction,and neurological deficit scores,showing a good efficacy of Qingkailing Injection. The common severe adverse reaction was anaphylaxis,and mild adverse reactions were skin and mucous membrane reactions. The most frequently combined drug was antibiotics,mainly Penicillin and Penicillin+Pioneeromycin. The existing evidences showed that the methodological quality of SRs of Qingkailing Injection needed to be improved and Qingkailing Injection had an obvious efficacy. However,the selection of outcome indicators for clinical trials and SRs shall be standardized,and the reporting of basic information,such as drug combination,shall be strengthened to provide more powerful clinical services.

This study aimed to analyze the methodological quality of systematic reviews of Shuxuening Injection and evaluate the efficacy and adverse reactions of Shuxuening Injection in the treatment of different diseases,in order to provide supportive evidence for clinical practice. Three Chinese databases and three English databases were retrieved to identify systematic reviews and Meta-analysis on the efficacy and safety of Shuxuening Injection in the treatment of diseases. The AMSTAR 2( a measurement tool to assess systematic reviews 2) tool was used to evaluate the methodological quality of the included systematic reviews,and tables were created to present the results of Meta-analyses. Twenty-four systematic reviews were included,all with very low methodological quality. Among the 16 AMSTAR-2 items,only 5 items had a compliance rate greater than 60. 0%,and 8 items had a compliance rate less than 50. 0%. For patients with cerebral infarction,Shuxuening Injection combined with conventional treatment was more effective than conventional treatment alone in terms of clinical efficiency and neurological deficit improvement. For patients with angina pectoris,Shuxuening Injection was superior to Danshen/Compound Danshen Injection in terms of the total effective rate of angina pectoris and total effective rate of ECG. The efficacy of Shuxuening Injection combined with conventional treatment is significantly better than conventional treatment.Shuxuening Injection( alone or combined with conventional treatments) was better than conventional treatments for cerebral hemorrhage,ischemic cerebrovascular disease,chronic pulmonary heart disease,vertigo and sudden deafness. Shuxuening Injection had better efficacy and lower incidence of adverse reactions,but the methodological quality of included systematic reviews was low. The results of this study still need to be verified by high-quality systematic reviews.

BACKGROUND: As single-cell sequencing technology has been gradually introduced, it is essential to characterize global collaboration networks and map development trends over the past 20 years. OBJECTIVE: The aim of this paper was to illustrate collaboration in the field of single-cell sequencing methods and explore key topics and future directions. METHODS: Bibliometric analyses were conducted with CiteSpace and VOSviewer software on publications prior to November 2019 from the Web of Science Core Collection about single-cell sequencing methods. RESULTS: Ultimately, we identified 2489 records, which were published in 495 journals by 14,202 authors from 1970 institutes in 61 countries. There was a noticeable increase in publications in 2014. The United States and high-income countries in Europe contributed to most of the records included. Harvard University, Stanford University, Karolinska Institutes, Peking University, and the University of Washington were the biggest nodes in every cluster of the collaboration network, and SA Teichmann, JC Marioni, A Regev, and FC Tang were the top-producing authors. Keywords co-occurrence analysis suggested applications in immunology as a developing research trend. CONCLUSIONS: We concluded that the global collaboration network was unformed and that high-income countries contributed more to the rapidly growth of publications of single-cell sequencing technology. Furthermore, the application in immunology might be the next research hotspot and developmental direction.

BACKGROUND: The coronavirus disease 2019 (COVID-19) has caused a worldwide pandemic, and traditional Chinese medicine (TCM) has played an important role in response. We aimed to analyze the published literature on TCM for COVID-19, and provide reference for later research. METHODS: This study searched the CBM, CNKI, PubMed, and EMBASE from its establishment to March 11, 2020. VOSviewer 1.6.11 and gCLUTO 2.0 software were used to visually analyze the included studies. RESULTS: A total of 309 studies were included, including 61 journals, 1441 authors, 277 institutions, and 27 provinces. Research collaborations among regions were among those close in geographical distance. The collaborations of institutions and authors were more likely to be restricted to the same region. Among the authors with frequency greater than two (65 authors), only 19 authors had connection with others. More than 70% (358/491) of keywords were only presented once, and 20 keywords were shown more than 10 times. Five research topics were identified: Data mining method based analysis on the medication law of Chinese medicine in prevention and management of COVID-19; exploration of active compounds of Chinese medicine for COVID-19 treatment based on network pharmacology and molecular docking; expert consensus and interpretation of COVID-19 treatment; research on the etiology and pathogenesis of COVID-19; and clinical research of TCM for COVID-19 treatment. CONCLUSION: The research hotspots were scattered, and the collaboration between authors and institutions needed to be further strengthened. To improve the quality and efficiency of research output, the integration of scientific research and resources, as well as scientific collaboration are needed.
ABSTRACT
OBJECTIVES: Relevant guidelines and consensuses for COVID-19 contain recommendations aimed at optimising the management in paediatric wards. The goal of this study was to determine the quality of those recommendations and provide suggestions to hospital managers for the adjustment of existing hospital prevention and control strategies, and also to offer recommendations for further research. DESIGN: A rapid review of the guidelines and consensuses for the management in paediatric wards facing COVID-19. METHODS: PubMed, EMBASE, the Cochrane Library, UpToDate, China National Knowledge Infrastructure, the Wanfang database and relevant websites such as medlive.cn, dxy.cn, the National Health and Health Commission and the China Center for Disease Control and Prevention were systematically searched through late May 2020. The Appraisal of Guidelines for Research and Evaluation II (AGREE II) tool was then used to assess the quality of the selected articles and summarise the relevant evidence concerning management in paediatric wards. RESULTS: A total of 35 articles were included, composed of 3 consensus guidelines, 25 expert consensuses and 7 expert opinions. Of the 35 papers, 24 were from China, 2 from the USA, 1 from Spain, 1 from Brazil, 1 from Saudi Arabia and 6 from multinational cooperative studies. Scores for the six domains of the AGREE II tool (scope and purpose, stakeholder involvement, rigour of development, clarity of presentation, applicability and editorial independence) were 98.57%, 53.57%, 17.92%, 69.62%, 26.96% and 50.35%, respectively. Recommendations for nosocomial infection and control, human resource management as well as management of paediatric patients and their families were summarised. CONCLUSIONS: Due to the outbreak of COVID-19, the quality of rapid guidelines and consensuses for the management in paediatric wards affected by COVID-19 is unsatisfactory. In the future, it will be necessary to develop more high-quality guidelines or consensuses for the management in paediatric wards to deal with nosocomial outbreaks in order to fully prepare for emergency medical and health problems.

Coronavirus disease 2019(COVID-19) is a newly emerged and highly contagious respiratory disease. Traditional Chinese medicine(TCM) has both systematism theory knowledge and clinical practical value in the prevention and treatment of COVID-19. Therefore, it was particularly important to examine the effect of TCM in the prevention and treatment of COVID-19. The patents of TCM might reflect the latest progression of scientific research. We aimed to provide reference for the prevention and treatment of COVID-19 by extracting and analyzing the TCM patents from the Patent Information Sharing Platform of COVID-19. The antiviral TCM patents were screened and exported from the Patent Information Sharing Platform. VOSviewer 1.6.14 was used to visualize and analyze the network of TCM in these patents. There were total 292 TCM patents, including 52 patents for etiological treatment and 240 patents for symptomatic treatment. Thirty-two provinces and 1 076 inventors were involved, mainly from Beijing, Guangdong and Jiangsu. Overall, there were 356 TCMs, 71 single prescriptions, and 221 compound prescriptions. The patents for treatment of coronavirus mainly focused on the treatment of coronavirus, while the patents for symptomatic treatment mainly focuses on the improvement of respiratory symptoms, such as fever and cough. There were 14 highly frequently used TCMs, including Glycyrrhizae Radix et Rhizoma, Scutellariae Radix, Lonicerae Japonicae Flos, Forsythiae Fructus, Isatidis Radix, Astragali Radix, Menthae Haplocalycis Herba, Gypsum Fibrosum, Houttuyniae Herba, Isatidis Folium, Rhei Radix et Rhizoma, Gardeniae Fructus, Platycodonis Radix, Armeniacae Semen Amarum. The analyzed results of the TCM patents from the patent information sharing platform of COVID-19 were consistent with the Guideline of Diagnosis and Treatment of COVID-19(7th edition), and the combination of TCM in each cluster may also provide future directions for drug compatibility.

BACKGROUND: Multiple gastrointestinal stromal tumors (MGISTs) are a very rare type of gastrointestinal stromal tumor (GIST) and are usually observed in syndrome. AIM: The paper aimed to describe the clinical and oncological features of MGISTs and to offer evidence for the diagnosis and treatment. METHODS: Data of consecutive patients with MGISTs who were diagnosed at Peking University People's Hospital (PKUPH) from 2008 to 2019 were retrospectively evaluated. Further, a literature search was conducted by retrieving data from PubMed, EMBASE, and the Cochrane library databases from inception up to November 30, 2019. RESULTS: In all, 12 patients were diagnosed with MGISTs at PKUPH, and 43 published records were ultimately included following the literature review. Combined analysis of the whole individual patient data showed that female (59.30%), young (14.45%), and syndromic GIST (63.95%) patients comprised a large proportion of the total patient population. Tumors were mainly located in the small intestine (58.92%), and both CD117 and CD34 were generally positive. After a mean 78.32-mo follow-up, the estimated median overall survival duration (11.5 years) was similar to single GISTs, but recurrence-free survival was relatively poorer. CONCLUSION: The clinical and oncological features are potentially different between MGISTs and single GIST. Further studies are needed to explore appropriate surgical approach and adjuvant therapy.

BACKGROUND: As a significantly important part of clinical practice, the professional nursing process can be advanced in many ways. Despite the fact that case reports are regarded to be of a lower quality grade in the hierarchy of evidence, one of the principles of evidence-based medicine is that decision-making should be based on a systematic summary of evidence. However, the evidence on the reporting characteristics of case reports in the nursing field is deficient. AIM: To use the CARE guidelines to assess reporting quality and factors influencing the quality of case reports in the nursing field. METHODS: Nursing science citation indexed (SCI-indexed) journals were identified from the professional website. Each of the identified journals was searched on their website for articles published before December 2017. Twenty-one sub-items on the CARE checklist were recorded as "YES", "PARTLY", or "NO" according to information reported by the included studies. The responses were assigned corresponding scores of 1, 0.5, and 0, respectively. The overall score was the sum of the 21 sub-items and was defined as "high" (more than 15), "medium" (10.5 to 14.5), and "low" (less than 10). The means, standard deviations, odds ratios (OR), and the associated 95% confidence interval (CI) were determined using Stata 12.0 software. RESULTS: Ultimately, 184 case reports from 16 SCI-indexed journals were identified, with overall scores ranging from 6.5 to 18 (mean = 13.6 ± 2.3). Of the included case reports, 10.3% were regarded low-quality, 52.7% were considered middle-quality, and 37% were regarded high-quality. There were statistical differences in the mean overall scores of the included case reports with funding versus those without funding (14.2 ± 1.7 vs 13.6 ± 2.4, respectively; P = 0.4456) and journal impact factor < 1.8 versus impact factor ≥ 1.8 (13.3 ± 2.3 vs 13.6 ± 2.4, respectively; P = 0.4977). Five items from the CARE guidelines, 5a (Patient), 6 (Clinical findings), 8c (Diagnostic reasoning), 9 (Therapeutic intervention), and 11d (The main take-away lessons) were well-reported (Reporting rate more than 90%) in most of the included case reports. However, only three items, 2 (Keywords, OR = 0.42, 95%CI: 0.19-0.92, P = 0.03), 4 (Introduction, OR = 0.35, 95%CI: 0.15-0.83, P = 0.017), and 11b (The relevant medical literature, OR = 0.19, 95%CI: 0.06-0.56, P = 0.003) were considered better-reported after the CARE guidelines published in 2013. CONCLUSION: The reporting quality of case reports in the nursing field apparently has not improved since the publication of the CARE guidelines.
ABSTRACT
BACKGROUND: To analyze the collaboration and reporting quality of the systematic reviews of social welfare in the Campbell collaboration online library. METHODS: The Campbell collaboration online library was searched for systematic reviews of social welfare and the basic information extracted in order to assess the reporting quality of systematic reviews using a MOOSE checklist. BICOMS-2 and UCINET software were used to produce the social network, and Comprehensive Meta Analysis (Version 2) and STATA 13.0 were used to analyze the related data. RESULTS: Fifty-seven systematic reviews of social welfare were included. Twenty-eight items of the included social welfare systematic reviews were rated as complete (≥70%). There were significant differences between ≤2013 and ≥ 2014 in five items. These differences were as follows: research published by one organization or more than one organization in one item, more than three authors or less than four authors in two items, and one country or more than one country in six items. It's completed about researches with more than one organization, three authors or more than one country. Some items were found to have a low reporting rate of studies published before 2014, by one organization, with less than four authors or one country, respectively. The social network of authors and organizations showed good collaboration. CONCLUSIONS: Some items could be further improved with regard to the rate of reporting systematic reviews of social welfare in the Campbell collaboration online library. This could improve the overall quality of social welfare systematic reviews.

BACKGROUND: N-of-1 trial is a desired and appropriate approach to assessing the efficacy and safety of traditional Chinese medicine (TCM) interventions. There have been an increasing number of N-of-1 trials for TCM published. However, a lack of preferred reporting guidance led in the general poor reporting quality of these trials. Due to the unique characteristics of TCM, the working group developed this CONSORT Extension for reporting N-of-1 Trials for Traditional Chinese Medicine (CENT for TCM) to assist TCM researchers in reporting N-of-1 trials for TCM. METHODS: We registered CENT for TCM at the EQUATOR (Enhancing the QUAlity and Transparency Of health Research) Network (available at equator-network.org). The development was a comprehensive process through collection of the initial reporting items, two-round scientific Delphi consensus survey with 17 panelists, revision and formation of the final reporting checklist. RESULTS: The checklist includes 25 items within six domains, eight items in which were extended and elaborated on the items of the CENT 2015 checklist. Explanation of the items were listed adequately considering the nature of TCM, introducing the concept of TCM syndrome differentiation and TCM interventions. CONCLUSIONS: CENT for TCM can be used to assess the completeness of the reporting of N-of-1 trials for TCM. The working group expect that CENT for TCM could be a practical tool to enhance the comprehensiveness and transparency of the design, implementation and reporting of N-of-1 trials for TCM.

To systematically review clinical practice guidelines (CPGs) on diabetes foot and assess the consistency of recommendations, quality of CPGs and to present an evidence-map for explicating research trends and gaps. We performed a literature search on PubMed, Embase, and Web of Science, guideline databases and websites of diabetes society to include the diabetic CPGs. The basic information, recommendations for the diabetic foot, methodological quality and reporting quality of diabetic CPGs were exacted by the Excel. Four researchers evaluated the methodological and reporting quality of diabetic foot CPGs by AGREE II instrument and RIGHT checklist. R3.5.1 software was used to create all bubble plots. A total of 22 diabetic CPGs were included, eight CPGs were from different professional diabetes societies. Recommendations on diabetic foot complications involve Diabetic foot ulcer (DFU), Charcot neuropathy (CN) and Osteomyelitis (OM). Eight DFU diagnostic systems presented in 22 CPGs. According to the recommendations of diabetic CPGs, the treatment of DFU can be summarized in four major items; six recommendations on CN diagnosis and six recommendations on treatment of CN were consistent among studies. However, there were inconsistencies in three OM diagnosis recommendations and four OM treatment recommendations. Some recommendations in CPGs were not very specific and clear, and hence they were not reliable for OM diagnosis and treatment. Once these inconsistencies are resolved, validated, accurate and effective diagnosis and treatment of diabetes foot will lead to reduced costs and adverse complications. The results of this review add to our knowledge and promote the development of trustworthy CPGs on diabetes.

OBJECTIVES: It remains uncertain which catheter lock solution (CLS) to prevent catheter-related bloodstream infections (CRBSI) works best and is safest for patients. This study was performed to compare the efficacy of different CLSs for the prevention of CRBSI and ranked these CLSs for practical consideration. METHODS: The PubMed, Web of Science, Embase, and MEDLINE databases, earlier relevant meta-analyses, and the reference lists of included studies were searched. The primary outcome was CRBSI; secondary outcomes were catheter-related thrombosis and exit-site infections. A network meta-analysis was performed to estimate odds ratios (ORs) with 95% confidence intervals (CIs). RESULTS: A total of 52 randomized controlled trials involving 9099 patients and evaluating 13 CLSs (single and combinations) were included. With regard to the quality of the evidence, the risk of bias was typically low or unclear (45 out of 52 trials, 86.5%). In the network meta-analysis, saline (OR 8.44, 95% CI 2.19-32.46), gentamicin+citrate (OR 2.92, 95% CI 1.32-6.42), ethanol (OR 5.33, 95% CI 1.22-23.32), and cloxacillin+heparin (OR 2.07, 95% CI 1.19-5.49) were associated with a greater effect on CRBSI than heparin. CONCLUSIONS: This network meta-analysis showed that minocycline-ethylenediaminetetraacetic acid (EDTA) seemed to be the most effective for the prevention of CRBSI and exit-site infection, and cefotaxime+heparin seemed to be the most effective for catheter-related thrombosis.

AIM: To assess the methodological and reporting quality of paediatric clinical practice guidelines (CPGs) in National Guideline Clearinghouse (NGC) using the Appraisal of Guidelines for Research and Evaluation (AGREE) II instrument and Reporting Items for Practice Guidelines in Healthcare (RIGHT) standard. METHODS: We identified all published CPGs through the NGC, and search records were screened in duplicate for inclusion. Two researchers evaluated the methodological and reporting quality of paediatric CPGs using the AGREE II instrument and RIGHT standard. STATA version 12.0 and SPSS version 22.0 software were used to analyse the related data. RESULTS: A total of 50 paediatric CPGs were included. The scores for all six domains by AGREE II instrument were presented as follows: scope and purpose (85.6 ± 9.59), stakeholder involvement (69.15 ± 19.32), rigour of development (73.19 ± 17.18), clarity of presentation (78.51 ± 14.36), applicability (54.61 ± 22.63) and editorial independence (68.42 ± 13.06). In the seven domains of the RIGHT standard, the reporting rate of the recommendation domain was the lowest (52.86%).The highest reporting rate was the other information domain, which was 68%.There was a high correlation between reporting the completeness of CPGs using the AGREE II instrument and RIGHT standard (r = 0.77, P < 0.001). CONCLUSIONS: The paediatric CPGs from NGC have good quality. There was a high correlation in the completeness of reporting for paediatric CPGs using the AGREE II instrument and RIGHT standard. It could be concluded that the CPGs of good methodological quality have good reporting quality. Maybe the researcher should effectively combine the AGREE II instrument and RIGHT standard in the development process of CPGs.

As a new concept in clinical research,the real world research(RWR) has attracted the attention of researchers in the world with its unique advantages. This research mainly analyzed it through visual methods,the specific steps were as follows. Firstly,the Chinese Biomedical Literature Database,China National Knowledge Infrastructure,Wan Fang Database,Medline and EMbase were searched and RWS were included,414 articles in Chinese and 2 158 articles in English were included in this research after layer-bylayer screening; secondly,the main information was extracted and sorted by BICOMS 2 software and generated its co-occurrence matrix; the network relationship diagram was drawn by Net Draw software; the cluster analysis was carried out by using g CLUTO software;finally,this research results show that the numbers of domestic and foreign literatures have shown an overall growth trend,but compared with foreign countries,China's research on the real world started late,the overall strength of research was not as good as abroad;and the domestic and foreign research on the real world was uneven in the region,the research in China was mainly distributed in developed provinces and cities,such as Beijing,Guangdong,Shanghai,etc,and there was a lack of close cooperation between provinces and cities; the foreign research are mainly distributed in developed countries such as the United States,the United Kingdom,Germany,et al; the cooperation between countries was relatively close. And the hotspots and core directions of domestic and foreign research were also different. This research was intended to provide reference for the further research of Chinese researchers through the current description of the themes and capability of the real world research in the world.
