Systematic Review and Meta-Analysis of Diagnostic Accuracy of miRNAs in Patients with Pancreatic Cancer

Background. It is reported that miRNAs are aberrantly expressed in patients with pancreatic cancer. However, the diagnostic value of miRNAs in pancreatic cancer remains controversial. The meta-analysis was to access diagnostic accuracy of miRNAs in pancreatic cancer. Methods. PubMed, Scopus, Web of Science, Chinese National Knowledge Infrastructure (CNKI), WANFANG Data, China Biomedical Literature Database (CBM), and VIP databases were retrieved up to June 30, 2016, to collect articles concerning the diagnosis of miRNAs in pancreatic cancer. The methodological quality of each study was assessed by the Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2). This meta-analysis was conducted using RevMan5.0, MetaDiSc 1.4, and Stata 12.0 software. Results. There are 40 articles including 109 studies. The pooled SEN was 0.81 (95% CI, 0.80–0.82), the pooled SPE was 0.78 (95% CI, 0.77–0.79), the pooled +LR was 3.32 (95% CI, 2.92–3.80), the pooled −LR was 0.27 (95% CI, 0.24–0.31), the pooled DOR was 14.56 (95% CI, 11.55–18.34), and pooled AUC was 0.86 (95% CI, 0.84–0.88). Discussion. This meta-analysis demonstrated that miRNA makes a significant impact in the pancreatic cancer diagnosis with a high SEN and SPE, particularly using multiple miRNAs.

Background: CD44 has recently been reported as a biomarker for pancreatic cancer. However, the predictive value of CD44 in pancreatic cancer remains controversial. Therefore, we performed this meta-analysis to evaluate the association between the expression of CD44 and clinicopathological features, and the outcome of pancreatic cancer patients. Materials and method: A comprehensive literature search was performed using PubMed, Embase, and Chinese National Knowledge Infrastructure. The statistical analysis was conducted using Stata software. Results: A total of nine studies including 583 cases were included in this meta-analysis. The meta-analysis indicated that CD44 overexpression was associated with poor five-year overall survival rate (OR 0.52; 95% CI 0.30, 0.91; P = 0.02), more lymph node invasion (OR 3.14 (positive vs. negative); 95% CI 1.47, 6.73; P = 0.003), more advanced T stage (OR 2.4 (T3,4 vs. T1,2); 95% CI 1.28, 4.52; P = 0.007), and more advanced TNM stage (OR 4.53 (III~IV vs. I~II); 95% CI 1.46, 14.08; P = 0.01). However, CD44 overexpression was not associated with other clinicopathological features, such as tumor size, differentiation, and distance metastasis. Conclusions: The current evidence suggests that CD44 is an efficient prognostic factor in pancreatic cancer.

OBJECTIVE: To conduct a systematic review of the literature and assess the effect of PM2.5 (particulate matter with diameter <2.5 μm) exposure on lung function in adults with asthma.METHODS: We searched all literature published between 1 January 2010 and 26 March 2019 in the EMBASE, PubMed, Cochrane Central Library, Chinese National Knowledge Infrastructure (CNKI), Wanfang and Chinese Biomedical Literature (CBM) databases. The studies were assessed for analytic methods, risk of bias and results of statistical analysis.RESULTS: The selected studies all had a low or moderate risk of bias. Overall, PM2.5 exposure was positively associated with a decrease in forced expiratory volume in 1 sec (FEV1)/forced vital capacity (FVC) in adults with asthma (standardised mean difference 0.20, 95% CI 0.02–0.38; P = 0.03).CONCLUSION: We observed a negative correlation between PM2.5 exposure and FEV1/FVC in patients with asthma. Our meta-analysis provides evidence suggesting that PM2.5 is a risk factor for acute asthma exacerbation in adults.

Objectives. This systematic review aims to critically evaluate the efficacy of manual acupuncture for optic atrophy. Eight English and Chinese databases, including Cochrane Library, EMbase, PubMed, Chinese National Knowledge Infrastructure (CNKI), Wanfang Database, China Science and Technology Journal Database (VIP), and Chinese Biomedical Literature Database (CBM), as well as ongoing trials registered with the WHO International Clinical Trials Registry Platform, were searched to identify eligible randomized controlled trials (RCTs) studying manual acupuncture for optic atrophy compared to medication alone. The quality of evidence was assessed using Cochrane Collaboration’s risk of bias tool. Meta-analysis was performed using Review Manager version 5.3. Nine studies were identified and included for meta-analysis. The meta-analysis showed significant differences in favor of manual acupuncture or manual acupuncture plus medication compared with medication alone in the following outcome measures: visual acuity (MD = 0.18, 95% CI [0.17, 0.20], P < 0.00001), mean sensitivity of visual field (MD = 2.11, 95% CI [1.90, 2.32], P < 0.00001), the latent period of P-VEP100 (MD = -6.80, 95% CI [-8.94, -4.66], P < 0.00001), the total effectiveness (264 eyes) (OR = 3.22, 95% CI [1.88, 5.51], P<0.0001), and the total effectiveness (344 participants) (OR = 4.29, 95% CI [2.56, 7.19], P < 0.00001). Despite statistical advantages of manual acupuncture in the literature, due to serious methodological flaws in study design, it cannot be concluded that manual acupuncture is more effective than medicine alone. It is essential that a properly controlled clinical trial is designed and controls are established to exclude placebo effects.

Abstract Background The importance of breastfeeding for maternal and child health has become an international consensus. However, it has been found that lactation-related nipple problems are common and there are some important factors affecting the effectiveness of breastfeeding. Multiple studies recommended the laid-back breastfeeding, but the researches are on various levels of quality and the results are controversial.Methods We systematically searched the following twelve databases: Cochrane Library, EMBASE, Medline, Ovid, PubMed, Web of Science, CINAHL, Scopus, SinoMed, Chinese National Knowledge Infrastructure (CNKI), WanFang, and VIP from inception to January 28,2020. All studies reporting the laid-back breastfeeding or biological nurturing were considered, regardless of they are randomized controlled trials. Two trained investigators independently evaluated the quality of the included the articles and screened the data. All the data were analyzed separately using Review Manager Version 5.3 and STATA/SE Version 15.1. Results A total of 12 studies involving 1,936 groups of postpartum women and their newborns were included. The results of meta-analysis showed that nipple trauma (RR = 0.47; 95% CI 0.29,0.75; p < 0.002), nipple pain (RR = 0.25; 95% CI 0.20,0.32; p < 0.00001), the correct posture of latching (RR = 1.22; 95% CI 1.11,1.33; p < 0.00001)and position comfort (ES = 0.01; 95%CI -0.28,0.30; p = 0.006) of experimental group were all better than control group, and the differences were statistically significant ( p < 0.05), which indicates that the laid-back position has a positive effect on maternal breastfeeding. Conclusion Laid-back position has significant advantages in decreasing the incidence of nipple trauma and nipple pain compared with traditional breastfeeding postures, and it appears that laid-back position is conducive to the correct posture of latching. However, current evidence does not show different breastfeeding outcomes in the two groups of position comfort. Laid-back position is helpful to solve lactation-related nipple problems and it can be used as a recommended position for breastfeeding.

Background. Emerging studies have explored the association between the famine exposure during early life and the risk of the metabolic syndrome, and the results remain controversial. This meta-analysis was performed to summarize the famine effects on the prevalence of metabolic syndrome (MetS) in adulthood. Materials and Methods. We searched the PubMed, Web of Science, Embase, ScienceDirect, and Chinese National Knowledge Infrastructure for relevant studies up to December 2019. Pooled odd ratios (ORs) with 95% confidence intervals (CIs) were used to estimate the effect exposure to famine on MetS using a random-effects model, and the I2 was used to evaluate the heterogeneity. Results. The analyses included 39 studies from 10 articles with a total of 81504 participants. Fourteen studies from 10 articles for fetal famine exposure, 20 studies from 7 articles for childhood famine exposure, and 5 studies from 3 articles for adolescence/adult famine exposure were included in this meta-analysis. Compared with a nonexposed group, famine exposure significantly increased the risk of MetS for early life famine exposure (OR=1.27, 95% CI: 1.18-1.38), fetal famine exposure (OR=1.27, 95% CI: 1.14-1.43), and childhood famine exposure (OR=1.29, 95% CI: 1.16-1.44). Subgroup analyses showed that the result was consistent regardless of the study designs, definitions of MetS, and causes of famine, with or without adjustment for age, smoking, drinking, and physical activity. Conclusions. This meta-analysis suggests that exposure to famine during early life may increase the risk of MetS in adulthood.

Objective. Our aim was to assess the efficacy and safety of acupuncture for OSA patients with various severities of the disorder. Methods. Eight databases including PubMed, Cochrane Library, EMBASE, Web of Science, China National Knowledge Infrastructure (CNKI), Chongqing VIP (CQVIP), Wanfang Data, and Chinese Biomedical Literature Database (CBM) were comprehensively searched till July 2019. Randomized controlled trials (RCTs) testing acupuncture in the treatment of OSA were eligible for inclusion. Studies were selected for inclusion, and data were extracted by two authors independently. The Cochrane Collaboration’s Risk of Bias Assessment Tool and RevMan software (version 5.3) were used to evaluate the quality of studies and conduct statistical analysis. Results. Nine RCTs with 584 participants were included. The trials covered acupuncture and electropuncture. Acupuncture caused clinically significant reductions in AHI (MD: -6.18; 95% CI: -9.58 to -2.78; Z=3.56, P=0.0004) as well as in ESS (MD: -2.84; 95% CI: -4.80 to -0.16, Z=2.09, P=0.04). AHI was reduced more in the subgroup analysis of moderate OSA patients (MD: -9.44; 95% CI: -12.44 to -6.45; Z=6.18, P<0.00001) and severe OSA patients (MD: -10.09; 95% CI: -12.47 to -7.71; Z=8.31, P<0.00001). ESS was also reduced more in the subgroup analysis of moderate OSA patients (MD: -2.40; 95% CI: -3.63 to -1.17; Z=3.83, P=0.0001) and severe OSA patients (MD: -4.64; 95% CI: -5.35 to -3.92; Z=12.72, P<0.00001). Besides, acupuncture had a beneficial effect on LSaO2 (MD: 5.29; 95% CI: 2.61 to 7.97; Z=3.86, P=0.0001). The outcome of AHI and LSaO2 yielded consistent results after sensitivity analysis, but the direction of the outcome of ESS was reversed. And the quality of evidence was mainly low to very low. Conclusions. Acupuncture therapy is effective for OSA patients in reducing AHI and ESS and in improving the LSaO2 of various severities, especially in moderate and severe OSA patients. High-quality trials are urgently needed.

Abstract Objective The objective of this study was to evaluate the effect of empowerment education on depression level and laboratory indicators of patients treated with hemodialysis. Methods We searched databases including Cochrane Library, Web of Science, Embase, PubMed, Chinese Biomedical Literature Database (CBM), Chinese Academic Journals Full-text Database (CNKI), VIP, and Wanfang. We included all the researches about the application of empowerment education in patients treated with hemodialysis. We used RevMan 5.3 to analyze the data after assessing the quality of researches. Results We included 10 studies eventually. The results of meta-analysis showed that the self-efficacy [MD = 1.10, 95% confidence interval (CI; 0.71, 1.48), P < 0.01], depression [MD = -6.94, 95% CI (-8.53, -5.34), P < 0.01], serum creatinine [Scr; MD = -116.46, 95% CI (-171.90, -61.03), P < 0.01], albumin [Alb; MD = 2.93, 95% CI (2.00, 3.86), P < 0.01], and blood urea nitrogen [BUN; MD = -0.95, 95% CI (-1.89, -0.01), P = 0.05] in the empowerment education group had significantly statistical difference compared with those in the usual education group. However, there was no significant difference in hemoglobin [Hb; MD = 3.03, 95% CI (-0.64, 6.70), P = 0.11] between two groups. Conclusions Empowerment education can improve the self-efficacy in patients treated with hemodialysis, relieve depression, and improve Scr, Alb, and BUN. However, there is no significant improvement in Hb; it needs further exploration in clinical practice.
