  • Diagnosis value of microRNA-1 for acute myocardial infarction: A meta-analysis

    ObjectiveTo systematically evaluate the clinical value of miRNA-1 in the diagnosis of acute myocardial infarction (AMI) patients.MethodsWe searched PubMed, EMbase, Cochrane Library, CNKI, Wangfang, VIP, etc databases to identify literature about miRNA-1 in the diagnosis of AMI. Quality of the included literature was assessed by (quality assessment for diagnostic accuracy studies-2, QUADAS-2). The indices of pooled sensitivity (Sen), specificity (Spe), positivity likelihood ratio (PLR), negative likelihood ratio (NLR), diagnosis odds ratio (DOR), and the area under the summary receiver operating characteristic (SROC) curve were pooled using MetaDisc 1.4 software.ResultsA total of 12 articles were included. According to the different populations of miRNA-1 to be tested, subgroup analysis of healthy people (7 articles) and non-AMI disease groups (5 articles) was conducted. The results showed that AMI compared with healthy people, the pooled Sen was 0.78 with 95%CI 0.73 to 0.82, Spe was 0.88 with 95%CI 0.83 to 0.91 of miRNA-1 in the diagnosis of AMI. AUC of SROC curve was 0.911 2. Comparison of AMI and non-AMI patients, the pooled Sen was 0.59 with 95%CI 0.54 to 0.64, Spe was 0.74 with 95%CI 0.68 to 0.79 of miRNA-1 in the diagnosis of AMI. AUC of SROC curve was 0.743 2.ConclusionMiRNA-1 has a certain value in the diagnosis of AMI. It has an advantage in identifying AMI and patients with other systemic diseases, and can be combined with other biomarkers to diagnose AMI.

  • Pulse Oximetry Screening for Congenital Heart Disease in Asymptomatic Children:A Systematic Review and Meta-Analysis

    Objective To investigate the accuracy of pulse oximetry screening for congenital heart disease (CHD) in asymptomatic children. Methods We electronically searched VIP database,CNKI database,CBMdisc,Wanfandatabase,PubMed,Excerpta Medica Database (EMBASE) and the Cochrane Library from the time of database establishment to February 2013 to identify literatures regarding pulse oximetry screening for CHD in asymptomatic children. Data extraction was performed by two researchers independently. Quality of the included literatures was evaluated with qualityassessment for diagnostic accuracy studies (QUADAS). Meta-analysis was performed using RevMan 5.1.1. ResultsTwelve studies were included in this study with a total of 137 582 newborns. Fourteen QUADAS criteria were fulfilled by all the 12 studies. Among the 12 studies,only the studies with positive test results received verification using a gold standardtest,and the execution of the gold standard test was described in sufficient detail only in 1 study. There were 10 studies in which the gold standard test results were interpreted with knowledge of the diagnostic test results. Meta-analysis showed that pooled sensitivity and specificity of pulse oximetry test for the diagnosis of CHD were 22% with 95% CI (19%,25%) and 99% (99%,99%) respectively. Pooled positive likelihood ratio (LR+) and negative likelihood ratio (LR-) were 157.30 with 95% CI (11.80,2 096.95) and 0.61 with 95% CI (0.46,0.82) respectively. Pooled diagnostic odds ratio was 398.25 (34.5,4 596.81). The area under summary receiver operating characteristic (SROC) curve was 0.809,and Q index was 0.744. Conclusion Pulse oximetry is a lowly sensitive and highly specific diagnostic method for children with CHD,and is helpful for early diagnosis of CHD.

  • Percutaneous closure of patent ductus arteriosus guided by transthoracic echocardiography or angiography: A systematic review and meta-analysis

    ObjectiveTo compare the efficacy of percutaneous closure guided by transthoracic echocardiography or angiography in the treatment of patent ductus arteriosus (PDA).MethodsLiterature databases such as CNKI, VIP, Wanfang Database, PubMed, Cochrane Library were searched for collecting published literatures on percutaneous closure for PDA guided by transthoracic echocardiography and angiography, retrieval time limit was up to April 2019. Two evaluators independently screened the literature, extracted the data and evaluated the quality according to inclusion and exclusion criteria. The collected data were analyzed by RevMan 5.3 software.ResultsEight studies were included finally, with a total sample size of 681 cases. Meta-analysis showed that there was no statistical difference in the operative success rate between the echocardiography group and the angiography group (RR=0.99, 95%CI 0.97- 1.01, P=0.40). Postoperative complications were less in the echocardiography group than those in the angiography group (RR=0.26, 95%CI 0.11-0.59, P=0.001).The operation time (P<0.000 01), amount of intraoperative radiation (P<0.000 01), exposure time (P<0.000 01), hospitalization days (P<0.000 01) and hospitalization costs (P<0.000 01) in the echocardiography group were less or shorter than those in the angiography group, and the difference was statistically different.ConclusionCompared with angiography-guided, transthoracic echocardiography-guided percutaneous closure for PDA is a safe and effective method with less trauma, lower cost, and can replace angiography as one of the guiding methods for PDA.
