Background: The aim of the study was to evaluate the diagnostic accuracy of cervical elastography in predicting preterm delivery (PTD). Methods: We searched the PubMed, EMBASE, and Cochrane databases to identify relevant studies that applied ultrasound (US) elastography to assess cervical stiffness and predict PTD. All the studies were published before December 11, 2018, and only studies published in English were collected. The cervical length (CL) was considered a comparator, and the Quality Assessment of Diagnostic Accuracy Studies-2 (QUADAS-2) tool was applied to assess the quality of the included studies. Summary receiver operating characteristic (SROC) modeling was performed to evaluate the diagnostic performance of cervical elastography in predicting PTD. Subgroup analyses were also performed. Results: Seven studies, including 1488 pregnant women, were included in this meta-analysis. Cervical elastography showed a summary sensitivity of 0.84 [95% confidence interval (CI): 0.68, 0.93], a specificity of 0.82 (95% CI: 0.63, 0.93), a diagnostic odds ratio of 25 (95% CI: 7, 93), and an area under the curve (AUC) of SROC of 0.90 (95% CI: 0.87–0.93). CL measurement showed that the AUC of SROC was 0.60 (95% CI: 0.56–0.64). The results of subgroup analysis showed that the summary sensitivity and specificity were different in the QUADAS-2 score subgroups. Conclusion: Cervical elastography is a promising and reliable method to predict PTD. Cervical elastography showed better diagnostic performance to predict PTD than CL measurement.
ObjectiveAs a classical immunosuppressant, tacrolimus (TAC) has been widely used in organ transplantation therapy, but the general benefits of TAC for the treatment of IgA nephropathy (IgAN) remain uncertain. We conducted a meta-analysis to examine the effects of TAC combined with glucocorticoid on IgAN.MethodsWe searched the information databases PubMed/Medline, Embase, Science Citation Index, Chinese Biomedical Literature and the Chinese databases VIP, CNKI and Wan Fang for randomized controlled trials of TAC combined with glucocorticoid as a therapy for IgAN.ResultsTen relevant studies involving 472 patients were included in a meta-analysis. Overall, the TAC group showed a significant decrease in proteinuria compared with the control group (MD: −0.18 g/d, 95% CI: −0.32 to −0.04). No increased risk of adverse events was observed (OR: 0.93, 95% CI: 0.65 to 1.33). In general, the TAC group showed good tolerance.ConclusionEvidence to date clearly indicates that TAC combined with glucocorticoid is quite effective in reducing proteinuria and albuminuria in patients with IgAN. Moreover, we found that patients receiving TAC therapy did not show an increased risk of side effects compared with control group patients. TAC combined with glucocorticoid is a promising medication and merits further research.
Aim The application of laparoscopic catheterization technology in peritoneal dialysis (PD) patients has recently increased. However, the advantages and disadvantages of laparoscopic versus conventional open catheterization are still controversial. The aim of this meta-analysis is to assess complications of catheterization in PD patients and to provide a reference for the clinical choice of PD catheter placement technique. Methods We searched numerous databases, including Embase, PubMed, CNKI and the Cochrane Library, for published randomized controlled trials (RCTs). Results Eight relevant studies (n=646) were included in the meta-analysis. The pooled results showed a lower incidence of catheter migration (P: 0.03, OR: 0.42, 95% CI: 0.19 to 0.90) and malfunction (P: 0.008, OR: 0.41, 95% CI: 0.21 to 0.79) but a higher incidence of bleeding (P: 0.02, OR: 3.25, 95% CI: 1.18 to 8.97) with a laparoscopic approach than with a conventional approach. There was no significant difference in the incidence of obstruction (P: 0.24, OR: 0.32, 95% CI: 0.05 to 2.10), hernia (P: 0.20, OR: 0.38, 95% CI: 0.09 to 1.68), leakage (P: 0.23, OR: 0.69, 95% CI: 0.38 to 1.26), mechanical dysfunction (P: 0.90, OR: 0.96, 95% CI: 0.48 to 1.91), malfunction (P: 0.008, OR: 0.41, 95% CI: 0.21 to 0.79), perforation (P: 0.97, OR: 0.95, 95% CI: 0.06 to 15.42), peritonitis (P: 0.13, OR: 0.95, 95% CI: 0.42 to 1.12) or tunnel or exit-site infections (P: 0.49, OR: 0.95, 95% CI: 0.71 to 2.02). Conclusion Laparoscopic catheterization and conventional open catheter placement in PD patients have unique advantages, but laparoscopic catheterization may be superior to conventional open catheter placement. However, this conclusion needs to be confirmed with further large-sample-size, multi-centre, high-quality RCTs.

However, this conclusion needs to be confirmed with further large-sample-size, multi-centre, high-quality RCTs.
