RESUMO

BACKGROUND: Antiphospholipid antibody syndrome (APS) is a systemic, autoimmune, prothrombotic disease characterized by persistent antiphospholipid antibodies, thrombosis, recurrent abortion, complications during pregnancy, and occasionally thrombocytopenia. At present, there is no consensus on the treatment of this disease. Long-term anticoagulation is recommended in most cases in patients with thrombotic APS. This study aimed to evaluate whether aspirin combined with low-molecular-weight heparin (LMWH) can improve the live birth rate in antiphospholipid syndrome and its correlation with D-dimer. METHODS: The data were retrieved from the WanFang Data, CBM, VIP, CNKI, the Cochrane Library, PubMed, EMBASE, OVID, and Web of Science databases. We collected data on randomized controlled trials of aspirin combined with LMWH in the treatment of pregnant women with APS. The "Risk of Bias Assessment" tool and the "Jadad Scale" provided by the Cochrane Collaboration were used to evaluate the risk of bias and quality of the collected literature. The risk ratio (RR) and its 95% confidence interval (CI) were determined using Statase-64 software. RESULTS: In this study, a total of 11 studies were included, comprising a total of 2101 patients. The live birth rate in pregnant women with APS was higher on administration of aspirin combined with LMWH than with aspirin alone (RR = 1.29, 95% CI = 1.22-1.35, P < .001). d-dimer concentration in plasma predicted the live birth rate, which was higher below the baseline than above it (RR = 1.16, 95% CI = 1.09-1.23, P < .001). The subgroup analysis of the live birth rate was carried out based on the course of treatment, and the results were consistent with the overall results. Begg funnel plot test revealed no publication bias. Sensitivity analysis showed that deleting any study did not affect the results. CONCLUSION: Aspirin combined with LMWH for APS may improve live birth rate, and detection of d-dimer levels in APS pregnant women may predict pregnancy complications and guide the use of anticoagulants.

RESUMO

BACKGROUND: ATPase family, AAA+ domain containing 2 (ATAD2) is also known as AAA+ nuclear coregulator cancer-associated protein or PRO2000. ATAD2 has been reported as a prognostic factor in different cancer types, but the association between ATAD2 high expression and survival is still unclear. Thereby, this meta-analysis was performed to evaluate the prognostic value of ATAD2 high expression in human cancers. METHODS: All of the studies included were retrieved from PubMed, EMBASE, and Cochrane Library electronic databases. The clinical outcomes were evaluated by calculating hazard ratio (HR) with their 95% confidence interval (CI). RESULTS: Thirteen studies including 2689 patients were eligible for this analysis. The pooled results showed that ATAD2 over-expression was significantly associated with shorter overall survival (OS) (HR = 2.32, 95% CI = 1.77-3.02), as well as shorter recurrence-free survival (RFS), disease-free survival (DFS), and disease-specific survival (DSS) (HR = 1.83, 95% CI = 1.51-2.23) among human cancers. Subgroup analyses for OS were implemented in terms of region, tumor type, and sample size and the results were coincident with overall pooled results. Begg funnel plot and Egger test showed the presence of publication bias for OS. Sensitivity analysis indicated that both results were not affected for removing any study. CONCLUSION: ATAD2 would be likely to act as a prognostic biomarker for the patients of different cancer types and provide a guide on clinical treatment. Prospective clinical studies are needed to support these findings.

RESUMO

BACKGROUND: Programmed cell death ligand 1 (PD-L1) overexpression has been reported to be associated with poor prognosis in several human cancers. However, studies on the prognostic value of PD-L1 expression in ovarian carcinoma (OC) remain controversial. This meta-analysis aimed to evaluate comprehensively the prognostic value of PD-L1 in OC. METHODS: Electronic databases, including PubMed, EMBASE, and the Cochrane Library, were searched up until March 28, 2018. Hazard ratio (HR), along with 95% confidence interval (CI), was used to analyze the included outcomes. RESULTS: A total of 10 studies with 1179 OC patients were included in this meta-analysis. There was no significant correlation between PD-L1 expression and overall survival (OS) (HR 1.23, 95% CI 0.85-1.79) and progression-free survival (PFS) (HR 0.88, 95% CI 0.52-1.47) of OC patients. However, the subgroup analysis suggested that positive PD-L1 expression was significantly associated with poor OS (HR 1.66, 95% CI 1.08-2.55) and PFS (HR 2.17, 95% CI 1.31-3.61) among OC patients from Asian countries. Increased PD-L1 expression was also a favorable factor for OS (HR 0.73, 95% CI 0.53-0.99) and PFS (HR 0.58, 95% CI 0.45-0.75) in OC patients from non-Asian regions. No evidence of publication bias was detected by the Egger linear regression test and Begg funnel plot. Sensitivity analyses suggested that the results of this meta-analysis were robust. CONCLUSIONS: The results indicated that PD-L1 expression may be a negative predictor for prognosis of OC patients from Asian countries, and a good predictor for favorable prognosis of OC patients from non-Asian countries. PD-L1 expression has potential to be a prognostic biomarker to guide clinicians for the selection of individuals who may get clinical benefit from anti-PD-1/PD-L1 immunotherapy. Prospective clinical studies are needed to support these findings.
