Abstract Background: Circular RNAs (circRNAs) are new stars in the network of noncoding RNAs and are regarded as key control factors in numerous tumours. The purpose of our study was to evaluate the clinical, prognostic and diagnostic role of circRNAs in colorectal cancer. The quality of all the articles were assessed by the Newcastle‐Ottawa Scale. Methods: An online search in electronic databases, including the PubMed, Cochrane Library and Web of Science online databases, was conducted to identify as many relevant papers as possible. Nineteen relevant studies were enrolled in this meta-analysis, with seven on diagnosis, eight on prognosis and 11 on clinicopathological features. Results: For the diagnostic value of circRNAs, the pooled results showed that the area under the curve (AUC) was 0.82 for identifying patients with colorectal cancer, with a sensitivity of 83% and a specificity of 72%. In terms of prognosis, carcinogenic circRNAs have a negative effect on overall survival (OS: HR = 2.29, 95% CI: 1.50-3.52), and increases in tumour suppressor circRNA expression are associated with longer survival (OS: HR = 0.37, 95% CI: 0.22-0.64). And the elevated expression of oncogenic circRNAs is associated with poor clinical features while tumor suppressor circRNAs are the complete opposite. Conclusions: These results suggest that circRNAs may be a potential biomarker for the diagnosis and prognosis of colorectal cancer.

This systematic review and meta-analysis aimed to investigate the efficacy of fluorescence-based methods, visual inspections, and photographic visual examinations in initial caries detection. A literature search was undertaken in the PubMed and Cochrane databases. Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guidelines were followed, and eligible articles published from 1 January 2009 to 30 October 2019 were included if they met the following criteria: they (1) assessed the accuracy of methods of detecting initial tooth caries lesions on occlusal, proximal, or smooth surfaces in both primary and permanent teeth (in clinical); (2) used a reference standard; (3) reported data regarding the sample size, prevalence of initial tooth caries, and accuracy of the methods. Data collection and extraction, quality assessment, and data analysis were conducted according to Cochrane standards Quality Assessment of Diagnostic Accuracy Studies-2. Statistical analyses were performed using Review Manager 5.3 and STATA 14.0. A total of 12 eligible articles were included in the meta-analysis. The results showed that the sensitivity and specificity of fluorescence-based methods were 80% and 80%, respectively; visual inspection was measured at 80% and 75%, respectively; photographic visual examination was measured at 67% and 79%, respectively. We found that the visual method and the fluorescence method were reliable for laboratory use to detect early-stage caries with equivalent accuracy.

Objective: To evaluate the diagnostic value of optical coherence tomography angiography (OCTA) in detecting the choroidal neovascularization (CNV) in agerelated macular degeneration (AMD). Methods: A systematic review and meta-analysis was performed by searching Pubmed, Science Direct, Embase and Web of Science. The pooled sensitivity and specificity with 95% confidence intervals (CIs), area under the summary receiver operator characteristic curve (sROC), and the total accurate classification rate were used to evaluate OCTA’ diagnostic value of CNV in AMD patients. Results: Seven studies involving 517 eyes were included in the analysis. The mean age of subjects in each study ranged from 58.5 years to 81.7 years. Fluorescein angiography was applied as the gold standard in five studies. There were 350 eyes diagnosed with CNV, OCTA detected 301 eyes correctly, while among the 167 eyes without CNV, OCTA identified 150 correctly. The total accurate classification rate was 87.23%. The Spearman's rank correlation coefficient was 0.5, indicating that there was no significant threshold effect in the current study (S=8, p=0.103). The pooled sensitivity and pooled specificity were 0.89 (95%CI: 0.82,0.94) and 0.96 (95%CI: 0.85,1.00) respectively. The area under sROC was up to 0.911. Conclusion: The specificity of OCTA for the detection of CNV in AMD patients is extremely high, however, the sensitivity still needs to be improved. In general, the metaanalysis revealed that OCTA had a high diagnostic value for the detection of CNV in AMD patients.
